Abstract

A reading device including an identification information reading device which reads the identification information, a holding device which holds an identification information application member, a moving device which moves the holding device relative to the identification information reading device, and a control device which controls operations of the identification information reading device, the holding device, and the moving device. The control device causes the holding device to move using the moving device such that at least a portion of the holding region in which the holding device holds the identification information application member is a reading region to move the identification information application member and is configured to perform a first reading process which carries out a reading process of the identification information using the identification information in a state in which holding of the identification information application member using the holding device is released.

Claims

1. A reading device which reads identification information of an identification information application member to which the identification information which indicates a kind of component to be mounted using a component mounting machine is applied, the device comprising:

an identification information reading device configured to read the identification information;

a holding device configured to hold the identification information application member;

a moving device configured to move the holding device relative to the identification information reading device; and

a control device configured to control operations of the identification information reading device, the holding device, and the moving device,

wherein the control device is configured to cause the identification information application member to move by moving the holding device with the moving device such that at least a portion of a holding region in which the holding device holds the identification information application member is in a reading region of the identification information reading device and to perform a first reading process of performing reading of the identification information using the identification information reading device in a state in which the identification information application member is released by the holding device, and

wherein the identification information application member is a wafer frame which holds a wafer and the holding device is a clamper that clamps the wafer frame.

2. The reading device according to claim 1,

wherein the control device is configured to move the holding device to a preset setting position with respect to the identification information reading device using the moving device, and to perform a second reading process of performing reading of the identification information using the identification information reading device in a state in which the holding device holds the identification information application member, and

wherein the control device is configured to perform the first reading process when the control device cannot read the identification information by using the second reading process.

3. The reading device according to claim 1,

wherein when the control device cannot read the identification information using the first reading process, the control device is configured to move the holding device with respect to the identification information reading device using the moving device in a state in which the holding device is in contact with an end surface of the identification information application member such that the holding region passes the reading region of the identification information reading device, and to perform a second reading process which reads the identification information using the identification information reading device.

4. The reading device according to claim 1,

wherein the control device is provided with a memory section which stores positional information of the holding device with respect to the identification information reading device when the identification information reading device is able to read the identification information, and

wherein, in a case in which the positional information is stored in the memory section in the first reading process, the control device drives the moving device to move the holding device based on the stored positional information.

5. A management system comprising:

multiple of the reading devices according to claim 1; and

a management device which is configured to communicate with the multiple reading devices,

wherein the management device is provided with a positional information memory section which stores positional information of a holding device with respect to an identification information reading device when at least one of the multiple reading devices is able to read identification information of a component, and

wherein, in a case in which the positional information is stored in the positional information memory section in the first reading process, each of the control devices of the multiple reading devices receives the stored positional information from the management device and drives each of the moving devices to move each of the holding devices based on the positional information.
