Description

Technical Field

[0001] The present invention relates to the field of test systems, in particular to a test re-judgment return line. Background Art

[0002] Defective products often occur during the production process of electronic equipment. These defective products are unqualified products that do not meet the standards or whose components do not meet the factory standards. Therefore, electronic equipment must undergo testing and inspection from the production process to the factory to ensure the quality of the products before leaving the factory.

[0003] In the existing production of electronic equipment, especially the testing of the external structure of the equipment, manual re-judgment is often required as the final result of the secondary re-judgment. Defective products after computer testing need to be moved off the production line for manual re-judgment. After the re-judgment is completed, they are continued to be manually transported to the subsequent work section. However, according to the standard output rate of daily production, the frequency of defective products is relatively low. Using manual real-time removal for re-judgment and sending qualified products back to the subsequent work section wastes manpower and has extremely low time utilization. How to solve this problem? We have specially designed the present invention for this purpose. Summary of the Invention

[0007] The re-judgment chamber is provided with a sensing device for prompting that the number of devices to be re-judged has reached a set threshold;

[0008] The reflux conveying device is used to automatically receive the re-inspected equipment to be re-inspected, and automatically transmit the re-inspected qualified equipment to the qualified product station.

[0009] In one embodiment, the conveying device includes a first conveying slide, one end of which is provided at the outlet end of the testing device, and the other end of which extends to the docking port of the re-testing warehouse.

[0010] In one embodiment, the conveying device further includes a second conveying slide, one end of which is provided at the outlet end of the testing device and the other end is connected to the qualified product station, and the outlet end is provided with a docking port of the conveying device.

[0011] In one embodiment, the docking port of the conveying device is provided with a gripper device, and the gripper device is connected to the testing device by signal and places the device into the first conveying slide or the second conveying slide according to the received instruction.

[0012] In one embodiment, the re-judgment chamber is provided with several storage areas for placing the devices to be re-judged, each of the storage areas is provided with a sensing device for sensing the devices to be re-judged, and the re-judgment chamber is also provided with a comparison module, and a threshold is set in the comparison module. When the threshold is equal to the total number of devices to be re-judged fed back by the sensing device, the comparison module sends a prompt signal.

[0013] In one embodiment, a manual re-judgment platform is provided between the re-judgment warehouse and the reflux conveying device, and lifting and conveying devices are provided at both ends of the storage area. The lifting and conveying devices include an entrance lifting and conveying device that automatically conveys the equipment to be re-judged at the docking port of the re-judgment warehouse to the storage area, and an exit lifting and conveying device that automatically conveys the equipment to be re-judged in the storage area to the manual re-judgment platform.

[0014] In one embodiment, a storage bin is provided at the rear end of the reflux conveying device, and the storage bin includes a qualified product bin and a defective product bin. The manual review station is provided with a control module, and the reflux conveying device is docked with the qualified product bin and the defective product bin respectively through instructions from the control module.

[0015] In one possible implementation manner, the reflux conveying device is a lifting conveying device, and the reflux conveying device conveys qualified equipment to the corresponding qualified product warehouse and conveys defective products to the defective product warehouse.

[0016] In one embodiment, the first conveying slide is a bidirectional belt conveyor, the qualified product warehouse and the first conveying slide are at the same horizontal plane, the equipment placed on the qualified product warehouse can be transported in the reverse direction through the first conveying slide, and the clamping device can place the equipment into the second conveying slide according to the instructions of the interaction between the conveying device and the testing device.

[0018] Compared with the prior art, the test and re-judgment return line of the present invention has the following beneficial effects:

[0019] 1. The present invention uses a conveying device to transfer devices that have been judged as defective by the testing device to a re-testing warehouse for re-testing. When the number of devices in the re-testing warehouse reaches a set threshold, a prompt is issued, prompting operators to take their positions and manually re-test the devices stored in the re-testing warehouse in turn to further screen out defective products. Devices that have been judged as qualified after manual re-testing are then re-transferred back to the qualified product station via a return conveyor. Compared with the existing technology, the present invention does not require manual real-time observation and removal of defective products. Operators performing re-testing only need to arrive at the location for re-testing after the re-testing warehouse issues a prompt, and then transfer the re-tested qualified products to the qualified product station for continued processing in the subsequent work section. This fully improves time utilization efficiency, reduces unnecessary time waste, and saves a lot of manpower.

[0020] 2. The conveyor device is equipped with a first conveyor slide and a second conveyor slide, so that the equipment tested by the testing device can be conveyed to different locations according to whether it is qualified.

[0022] 4. By setting up an entrance lifting and conveying device and an exit lifting and conveying device, the equipment that needs to be re-inspected can be automatically transported and placed and automatically transported out in sequence according to the set program;

[0023] 5. The reflux conveying device automatically transports defective and qualified products to the defective and qualified product bins in the storage bin according to the instructions of the control module, facilitating subsequent docking;

[0024] 6. The first conveyor slide and the qualified product bin are on the same horizontal plane, so that qualified products in the qualified product bin are transported through the first conveyor slide and transferred back to the second conveyor slide. The structure is simple and reduces the space occupied by redundant structures.

[0025] 7. All devices are electrically connected to the main control room and receive unified deployment from the main control room;

[0026] Therefore, the present invention has the characteristics of improving time utilization, saving a lot of manpower, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the purposes, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] Example:

[0034] Figures 1 to 2 An embodiment of a test, re-judgment and reflow line of the present invention is presented, comprising a test device 1, a conveying device 2, a re-judgment bin 3, a manual re-judgment station 9, a reflow conveying device 4 and a storage bin 10, through which the equipment 11 passes in sequence. After the test device 1 determines that the equipment 11 to be tested is unqualified, it is transported back and forth to the re-judgment bin 3 through the conveying device 2. When the number of equipment 11 in the re-judgment bin 3 reaches a set threshold, a reminder is issued, and the operator comes to the manual re-judgment station 9 for re-judgment. After the re-judgment is completed, the unqualified defective products are uniformly sent to the defective product placement area of the storage bin 10, and the qualified products that pass the re-judgment are sent to the qualified product station 5 to continue the subsequent stage. The equipment 11 in this scheme is mainly electronic equipment, and the test device 1, the conveying device 2, the re-judgment bin 3, the reflow conveying device 4 and the storage bin 10 are all electrically connected to the main control room.

[0035] In this solution, the conveying device 2 is connected between the testing device 1 and the re-inspection warehouse 3 to realize the automatic transmission of the equipment 11 to be re-inspected from the testing device 1 to the re-inspection warehouse 3; a sensing device is set in the re-inspection warehouse 3 to issue a prompt for manual re-inspection when the number of equipment 11 to be re-inspected reaches a set threshold; the reflux conveying device 4 is used to receive the equipment 11 that has been manually re-inspected, and to convey the equipment 11 that has passed the re-inspection to the qualified product station 5.

[0036] Among them, the conveying device 2 of this scheme includes a first conveying slide 21, one end of the first conveying slide 21 is set at the exit end of the test device 1, and the other end extends to the docking port of the re-inspection warehouse 3. The conveying device also includes a second conveying slide 22, one end of the second conveying slide 22 is set at the exit end of the test device 1, and the other end is connected to the qualified product station 5. The exit end is provided with a docking port of the conveying device 2, and the docking port of the conveying device 2 is provided with a clamping device 23. When the instruction given by the test device 1 is unqualified, the clamping device 23 puts the device 11 into the first conveying slide 21, and when the instruction given by the test device 1 is qualified, the clamping device 23 puts the device 11 into the second conveying slide 22; wherein, the second conveying slide 22 is connected to the sky line docking station, and is transmitted to the next process for qualified products through the sky line docking station equipment 11. The sky line docking station is the port of the qualified product station 5. In this solution, the first conveying slide 21 and the second conveying slide 22 can be belt lines or screw slides. When a screw slide is used, a tray for placing the device 11 should also be provided.

[0037] like Figure 3 As shown, in this solution, a plurality of storage areas 6 for placing the devices to be re-judged 11 are provided in the re-judgment warehouse 3, a manual re-judgment platform 9 is provided between the re-judgment warehouse 3 and the reflux conveying device 4, and lifting and conveying devices are provided at both ends of the storage area 6, including an entrance lifting and conveying device 7 for conveying the devices to be re-judged 11 at the connection port of the re-judgment warehouse 3 to the storage area 6, and an exit lifting and conveying device 8 for conveying the devices to be re-judged 11 in the storage area 6 to the manual re-judgment platform 9; wherein, in this solution, the storage area 6 is provided with ten layers, with two layers arranged side by side on each layer, and each storage area 6 is provided with a sensing device, and a comparison module is also provided in the re-judgment warehouse 3, and the comparison module is set with an upper limit threshold, such as the setting of the re-judgment threshold. The upper limit threshold of the number of devices 11 in the judgment warehouse 3 is 18 or 20. The main control room controls the entrance lifting and conveying device 7 to automatically transport the devices 11 to the storage area 6 in order from bottom to top and from one end to the other. When the total number of devices 11 sensed by the sensing device reaches 18 or 20, the set threshold is triggered, and the comparison module compares with the sensing device. When it is found that the set threshold is reached, a prompt is issued. For example, the operator can be called to the manual re-judgment station 9 to re-judgment the device 11 by connecting a buzzer device or feeding back to the main control room. During the re-judgment, the exit lifting and conveying device 8 is used to transport the devices 11 from the storage area 6 in order.

[0038] It should be noted that all devices that need to be transported in this solution can be transported by belt lines. As long as the front and rear devices are on the same horizontal line, transportation docking can be achieved. It should be emphasized that the storage area 6 is also composed of belt lines, and a section of belt line forms a storage area 6.

[0039] like Figure 3 and Figure 4As shown, a storage bin 10 is provided at the rear end of the reflux conveying device 4. The storage bin 10 has five layers, including a qualified product bin 101 on the top layer and a defective product bin 102 on the lower four layers. The reflux conveying device 4 is a lifting conveying device that can move up, down, left and right. The manual re-inspection platform 9 is provided with a control module. The reflux conveying device 4 is connected to the control module signal. After the operator obtains the result of the re-inspection of the equipment 11, the control module gives a qualified or defective instruction. The reflux conveying device 4 moves the equipment 11 up or down and sends it to the qualified product bin 101 or the defective product bin 102.

[0040] Preferably, in this solution, in order to further reduce the number of intermediate steps, a button can be set on the reflux conveying device 4 in this solution, that is, the qualified or unqualified product, and the reflux conveying device 4 can be directly controlled by the operator pressing the button.

[0041] The equipment 11 placed in the qualified product warehouse 101 needs to be transported to the skyline docking station. In this solution, in order to make the structure simpler and reduce space occupancy, the first conveying slide 21 is a bidirectional belt conveyor, so that the equipment 11 can be transported to the re-inspection warehouse 3 through the first conveying slide 21, and can also be transported back to the docking port of the conveying device from the storage warehouse 10 through the first conveying slide 21. The qualified product warehouse 101 and the first conveying slide 21 are at the same horizontal plane, so that the equipment 11 placed on the qualified product warehouse 101 is transported back to the clamping device 23 through the first conveying slide 21 and placed in the second conveying slide 22.

[0042] In actual application, the frequency of the device 11 in this solution from the outlet end of the testing device 1 to the docking port of the conveying device is one every 12 seconds, and the speed of transporting the device 11 back to the docking port of the conveying device from the qualified product warehouse 101 is between 3-4 seconds. When it is observed that the number of qualified devices 11 that have passed the re-inspection in the qualified product warehouse 101 is about to be full, the qualified devices 11 that have passed the re-inspection can be transported to the second conveying slide 22 during the 12-second interval when the device 11 test occurs by setting a button trigger connected to the main control room or setting a sensing device.

[0043] In this solution, the test device 1 is AFT, i.e., automatic performance test, the main control room is EMS system, i.e., manufacturing enterprise production process execution management system, and the conveying device is a transfer machine.

[0044] Specific working principle: The basic information of the equipment 11 that has passed the AFT test is uploaded to the MES system in real time through AFT. The MES system sends back a signal, and AFT interacts with the transfer machine to transmit the signal of whether the equipment 11 is qualified or not. When the equipment 11 is qualified, the clamping device 23 delivers the equipment 11 to the second conveying slide 22 on the transfer machine, so that the equipment 11 passes through the second conveying slide 22 to the sky line docking station; when the equipment 11 is defective, the clamping device 23 delivers the equipment 11 to the first conveying slide 21 on the transfer machine, so that the equipment 11 passes through the first conveying slide 21 to the re-judgment warehouse 3. Under the control of the MES system, the entrance lifting and conveying device 7 in the re-judgment warehouse 3 receives the equipment 11 and arranges them in sequence according to the distribution of the storage area 6. They are all conveyed by belt lines, so when the number of devices 11 in the re-inspection warehouse 3 reaches the set threshold, a prompt is issued to call the operator, and the exit lifting device moves up, down, left and right in order according to the arrangement of the storage area 6 to convey the devices 11 to the manual re-inspection platform 9 in sequence; if the device 11 is qualified in the re-inspection, the operator transfers the device 11 to the reflux conveying device 4 and activates the corresponding instruction button, and the reflux conveying device 4 moves up and sends the qualified products to the qualified product warehouse 101. If the device 11 is re-inspected as a defective product, the operator transfers the device 11 to the reflux conveying device 4 and activates the corresponding instruction button, and the reflux conveying device 4 moves up or down to send the defective products to the defective product warehouse 102 in sequence. When each layer is full, the reflux conveying device 4 automatically adjusts to the next layer for transmission.

[0045] When the qualified product warehouse 101 is about to be full, the device 11 is transported from the qualified product warehouse 101 to the first conveying slide 21, and is transported in the opposite direction to the docking port of the conveying device with the device 11 to be re-inspected. The clamping device 23 grabs the qualified products and transports them to the second conveying slide 22 to the sky line docking station.
