Description

Technical Field

[0001] This utility model relates to the field of PCBA board bottom shell technology, and more specifically, to a fully automatic testing device for PCBA board bottom shells. Background Technology

[0002] PCBA boards are finished products after electronic components are mounted and soldered onto a printed circuit board (PCB). They are responsible for connecting and transmitting electronic signals, ensuring the normal operation of electronic devices. The bottom shell of the PCBA board, as part of its external structure, not only protects the internal electronic components from physical damage but also helps with heat dissipation and electromagnetic shielding, thereby ensuring the stability and reliability of electronic devices. To improve product quality, the bottom shell of the PCBA board needs to be inspected before leaving the factory.

[0003] A search revealed that Chinese Patent CN220583325U discloses a shell deformation detection device. This device features an electric telescopic rod. Activating a hydraulic cylinder drives the hydraulic rod to rise and fall, which in turn drives a connecting component. This component drives a first motor, which in turn drives the electric telescopic rod to rise and fall. Once adjusted to a suitable height, the electric telescopic rods on both sides extend and retract to clamp the shell. The first motor drives the electric telescopic rods to rotate, causing the clamped shell to rotate as well. A scanner detects the deformation of the shell clamped by the electric telescopic rods and uploads the data to a display, thus providing a comprehensive inspection of the shell and improving the device's practicality.

[0004] When the above-mentioned testing equipment is used to test the bottom shell of a PCBA board, it uses a scanner to test the bottom shell of the PCBA board held by an electric telescopic rod. However, during the test, the bottom shell of the PCBA board needs to be placed manually on one side of the electric telescopic rod, and only one bottom shell of the PCBA board can be tested at a time, resulting in low testing efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a fully automatic inspection device for PCBA board bottom shell, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic PCBA board bottom shell inspection device, comprising a base, a conveyor belt, and an inspection instrument body, wherein the conveyor belt is fixedly installed at the top of the base, the inspection instrument body is located at the top of the conveyor belt, a support frame is fixedly connected to the bottom of the inspection instrument body, and the support frame is fixedly installed at the top of the base, an adsorption component is provided between the support frame and the conveyor belt, the adsorption component includes a negative pressure fan, a multi-way air pipe, and three air inlets, the input end of the negative pressure fan is fixedly connected to the multi-way air pipe, the rear ends of the three air inlets are all fixedly connected to the multi-way air pipe, an adjustment component is provided on the negative pressure fan, the adjustment component includes a connecting frame, a first self-locking motor, a first rotating shaft, and a fixing plate, and the negative pressure fan is mounted on the fixing plate.

[0007] Furthermore, valves are movably installed on the rear side of each of the three air intake hoppers, and all three valves are fixedly installed on the multi-port air pipe.

[0008] As can be seen, in the above technical solution, when all three valves are opened, the adsorption range can be increased, making it easier to adsorb PCBA board bottom shells of different lengths.

[0009] Furthermore, the first self-locking motor is fixedly installed on the rear side of the connecting frame, and the output shaft end of the first self-locking motor is fixedly connected to the first rotating shaft, and the front end of the first rotating shaft is fixedly connected to the fixing plate.

[0010] Furthermore, a hydraulic cylinder is fixedly connected to the bottom end of the connecting frame, and the bottom end of the hydraulic cylinder is fixedly connected to the base.

[0011] It can be seen that the above technical solution is designed to facilitate the adjustment of the height of the PCBA board bottom shell.

[0012] Furthermore, a side plate is fixedly connected to one side of the support frame, and a guide assembly is provided on the side plate. The guide assembly includes a second self-locking motor, a second rotating shaft, and a guide plate.

[0013] Furthermore, the second self-locking motor is fixedly installed on the top of the side plate, and the output shaft end of the second self-locking motor is fixedly connected to the guide plate, and the bottom end of the second rotating shaft is fixedly connected to the guide plate.

[0014] It can be seen that the above technical solution is designed to facilitate the guidance of the bottom shell of the unqualified PCBA board.

[0015] Furthermore, a storage box is movably provided on the front side of the guide plate, and a limiting frame is movably provided at the bottom edge of the outer side of the storage box, and the limiting frame is fixedly installed at the top front edge of the base.

[0016] As can be seen, in the above technical solution, the storage box is finally moved upward and away from the limit frame, and multiple defective PCBA board bottom shells are taken out from the storage box.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses a conveyor belt to transport multiple PCBA board bottom shells. The main body of the detector automatically detects the PCBA board bottom shells. A negative pressure fan generates suction, causing the PCBA board bottom shells to adhere to the front side of the air inlet. The piston rod on the hydraulic cylinder extends, causing the PCBA board bottom shells to move upward. The first self-locking motor rotates the PCBA board bottom shells. The main body of the detector can perform comprehensive detection on the outer side of the PCBA board bottom shells. Similarly, the detector can detect another PCBA board bottom shell, and so on, resulting in high detection efficiency and good detection effect.

[0019] 2. This utility model uses a second self-locking motor to drive a second rotating shaft, which in turn drives a guide plate to rotate. The guide plate is tilted at the top of the conveyor belt, guiding defective PCBA board bottom shells and causing them to fall into the storage box. Similarly, the second self-locking motor reverses to drive the guide plate to rotate parallel to the edge of the conveyor belt, allowing qualified PCBA board bottom shells to pass through the guide plate normally. The structure is simple and easy to use. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1-5 This embodiment of a fully automatic PCBA board bottom shell testing device includes a base 1, a conveyor belt 2, and a testing instrument body 8. The conveyor belt 2 is fixedly installed on the top of the base 1, and the testing instrument body 8 is located on the top of the conveyor belt 2. A support frame 3 is fixedly connected to the bottom of the testing instrument body 8, and the support frame 3 is fixedly installed on the top of the base 1. An adsorption component 5 is provided between the support frame 3 and the conveyor belt 2. The adsorption component 5 includes a negative pressure fan 501, a multi-way air pipe 502, and three air inlets 503. The input end of the negative pressure fan 501 is fixedly connected to the multi-way air pipe 502, and the rear ends of the three air inlets 503 are all fixedly connected to the multi-way air pipe 502. An adjustment component 4 is provided on the negative pressure fan 501. The adjustment component 4 includes a connecting frame 402, a first self-locking motor 403, a first rotating shaft 404, and a fixing plate 405, and the negative pressure fan 501 is installed on the fixing plate 405.

[0029] Furthermore, valves 504 are movably installed on the rear side of each of the three air intake hoppers 503, and the three valves 504 are fixedly installed on the multi-port air pipe 502. The first self-locking motor 403 is fixedly installed on the rear side of the connecting frame 402, and the output shaft end of the first self-locking motor 403 is fixedly connected to the first rotating shaft 404. The front end of the first rotating shaft 404 is fixedly connected to the fixing plate 405. A hydraulic cylinder 401 is fixedly connected to the bottom end of the connecting frame 402, and the bottom end of the hydraulic cylinder 401 is fixedly connected to the base 1.

[0030] Furthermore, a side plate 6 is fixedly connected to one side of the support frame 3. A guide assembly 7 is provided on the side plate 6. The guide assembly 7 includes a second self-locking motor 701, a second rotating shaft 702, and a guide plate 703. The second self-locking motor 701 is fixedly installed on the top of the side plate 6, and the output shaft end of the second self-locking motor 701 is fixedly connected to the guide plate 703. The bottom end of the second rotating shaft 702 is fixedly connected to the guide plate 703. A storage box 10 is movably provided on the front side of the guide plate 703. A limit frame 9 is movably provided at the bottom edge of the outer side of the storage box 10, and the limit frame 9 is fixedly installed at the top front edge of the base 1.

[0031] When the main body 8 of the detector detects a defective PCBA board bottom shell, the second self-locking motor 701 drives the second rotating shaft 702 to rotate, thereby driving the guide plate 703 to rotate and causing the guide plate 703 to tilt at the top of the conveyor belt 2.

[0032] The usage method of this embodiment is as follows:

[0033] In operation, multiple PCBA board bottom shells are conveyed via conveyor belt 2. When one of the PCBA board bottom shells moves to the bottom of the detector body 8, the detector body 8 automatically detects the PCBA board bottom shell, starts the negative pressure fan 501, and generates suction, causing the PCBA board bottom shell to adhere to the front side of the air inlet hopper 503. Then, the hydraulic cylinder 401 and the first self-locking motor 403 are activated. The piston rod on the hydraulic cylinder 401 extends, driving the connecting frame 402 to move upward, thereby driving the PCBA board bottom shell upward. At the same time, the first self-locking motor 403 drives the first rotating shaft 404. The rotation causes the fixed plate 405 and the PCBA board bottom shell to rotate, allowing the main body 8 of the detector to perform a comprehensive inspection of the outer side of the PCBA board bottom shell. Similarly, the same process is used to inspect another PCBA board bottom shell, and so on, resulting in high inspection efficiency and good inspection results. When all three valves 504 are open, the adsorption range can be increased, making it convenient to adsorb PCBA board bottom shells of different lengths. It is worth noting that the main body 8 of the detector is an AOI detector, which uses a high-resolution camera to capture images of the PCBA board bottom shell and uses advanced image processing technology to identify and mark potential welding defects.
