Description
Technical Field
[0001] This utility model relates to the technical field of circuit board testing, specifically to a circuit board testing equipment board feeding and receiving mechanism. Background Technology
[0002] In electronic product manufacturing, the output of circuit boards is increasing daily. Traditional manual inspection and loading / unloading methods are inefficient and cannot meet the demands of mass production. For example, manually placing circuit boards into a feeding device and then transporting them to the inspection station is time-consuming and labor-intensive, resulting in low production efficiency. Therefore, a circuit board testing equipment feeding and receiving mechanism is needed. Existing circuit board testing feeding and receiving mechanisms typically involve first placing the circuit board on a circuit board rack with slots for the circuit boards. One circuit board is placed inside each slot. During feeding, push rods push the circuit board onto a conveyor mechanism on the testing equipment, which then delivers it to the inspection station. After testing, the circuit board is conveyed to a receiving assembly, which also has a circuit board rack. The conveyor mechanism delivers the circuit board to the slot in the circuit board rack, where push rods push the circuit board into the rack, completing the receiving process. However, the above-mentioned common circuit board testing equipment feeding and receiving mechanism still has shortcomings: Traditional circuit board racks can only hold one circuit board in each slot before a push rod can be used to send the circuit board into the test conveyor mechanism, which greatly affects the efficiency of testing. Utility Model Content
[0003] The purpose of this utility model is to provide a board feeding and receiving mechanism for a circuit board testing device, so as to solve the problem mentioned in the background art that when feeding boards, the traditional circuit board rack can only hold one circuit board in the slot before the circuit board can be sent into the test conveying mechanism by the push rod, which greatly affects the testing efficiency.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a board feeding and receiving mechanism for a circuit board testing device, comprising a device body, a board feeding groove at one end of the device body, a board receiving groove at the other end of the device body, mounting slots inside both the board feeding groove and the board receiving groove, and hydraulic units installed inside both mounting slots, with a board feeding assembly fixedly connected to the output end of one hydraulic unit and a board receiving assembly fixedly connected to the output end of the other hydraulic unit, board frame assemblies provided on the surfaces of both the board feeding assembly and the board receiving assembly, and a board feeding drive mechanism provided at one end of the top of the device body.
[0005] Preferably, the plate feeding assembly includes a plate feeding support plate, and a first colored light, a second colored light, and a third colored light are sequentially installed at the center of the top of the plate feeding support plate. Four plate feeding positioning blocks are fixedly connected to the outer side of the surface of the plate feeding support plate, which is beneficial to control the extension and retraction of the driving plate by turning the colored lights on and off.
[0006] Preferably, the plate retracting assembly includes a plate retracting support plate, which is fixedly connected to the hydraulic unit, and four plate retracting positioning blocks are fixedly connected to the outer side of the plate retracting support plate.
[0007] Preferably, the board frame assembly includes a circuit board frame, and the circuit board frame has multiple inner board slots inside.
[0008] Preferably, the board feeding drive mechanism includes two board feeding slides, both of which are mounted on the equipment body. A drive assembly is fixedly installed at the connection between the two board feeding slides and the equipment body. A board feeding push plate is slidably connected between the two board feeding slides. A transmission rack is fixedly connected to the bottom of the board feeding push plate. Two electric push rods are fixedly installed at one end of the board feeding push plate. A drive plate is fixedly connected to the output end of each of the two electric push rods. A color sensor is provided on one side of the connection between the transmission rack and the board feeding push plate. This helps to reduce the number of times the board feeding circuit board frame needs to be replaced and can greatly improve the testing efficiency.
[0009] Preferably, the drive assembly includes a drive motor, which is fixedly mounted on the device body. A transmission gear is fixedly connected to the output end of the drive motor, and one side of the transmission gear meshes with one side of the transmission rack.
[0010] Compared with the prior art, the beneficial effects of this utility model are: the push rod part in the board feeding assembly is improved so that two circuit boards are placed inside one slot of the board feeding circuit board holder. The end of the board feeding push plate is provided with a retractable drive plate. The extension and retraction of the drive plate is controlled by the color of the colored light received by the color sensor. The drive plate is driven by the drive assembly to enter between two adjacent circuit boards. When it reaches the circuit board in front, the drive plate extends to send out the circuit board. Then it retracts through the colored light, resets, and extends again to send out the circuit board in the back. This reduces the number of times the board feeding circuit board holder needs to be replaced, which can greatly improve the efficiency of testing. Attached Figure Description

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0014] Please see Figure 1-4 This utility model provides a board feeding and receiving mechanism for a circuit board testing device, including a device body 1. One end of the device body 1 has a board feeding groove 2, and the other end of the device body 1 has a board receiving groove 3. Both the board feeding groove 2 and the board receiving groove 3 have mounting grooves inside. Hydraulic units 4 are installed inside both mounting grooves. The output end of one hydraulic unit 4 is fixedly connected to a board feeding assembly, and the output end of the other hydraulic unit 4 is fixedly connected to a board receiving assembly. Board frame assemblies are provided on the surfaces of both the board feeding assembly and the board receiving assembly. A board feeding drive mechanism is provided at one end of the top of the device body 1.
[0015] See Figure 2 , Figure 3 and Figure 4Furthermore, the plate feeding assembly includes a plate feeding support plate 5, with a first colored light 8, a second colored light 9, and a third colored light 10 sequentially installed at the center of the top of the plate feeding support plate 5. Four plate feeding positioning blocks 7 are fixedly connected to the outer surface of the plate feeding support plate 5. The plate receiving assembly includes a plate receiving support plate 6, which is fixedly connected to the hydraulic unit 4. Four plate receiving positioning blocks 21 are fixedly connected to the outer surface of the plate receiving support plate 6. The plate frame assembly includes a circuit board frame 11, with multiple inner plate slots 12 opened inside the circuit board frame 11. The plate feeding drive mechanism includes two plate feeding slides 13, both of which are installed on the equipment body 1. The two plate feeding slides 13 are connected to the equipment body. A drive assembly is fixedly installed at the connection of 1. A feeding push plate 16 is slidably connected between the two feeding slides 13. A transmission rack 17 is fixedly connected to the bottom of the feeding push plate 16. Two electric push rods 19 are fixedly installed at one end of the feeding push plate 16. A drive plate 20 is fixedly connected to the output end of each of the two electric push rods 19. A color sensor 18 is provided on one side of the connection between the transmission rack 17 and the feeding push plate 16. The drive assembly includes a drive motor 14. The drive motor 14 is fixedly installed on the equipment body 1. A transmission gear 15 is fixedly connected to the output end of the drive motor 14. One side of the transmission gear 15 meshes with one side of the transmission rack 17. In use, initially, the electric push rod 19 is in the retracted state, and the drive plate 20 is also in the retracted state. The drive motor 14 is activated, driving the transmission gear 15 to rotate. Therefore, the feeding push plate 16 moves horizontally inside the feeding slide 13. When feeding the circuit board, the feeding push plate 16 is positioned between two circuit boards. At this time, the feeding push plate 16 moves through the gap between the two circuit boards. After placing two circuit boards in the inner slot 12 of the circuit board holder 11, there is a certain gap between the two circuit boards. When placing the circuit boards, they are placed from both sides of the circuit board holder 11 to maintain the gap between the two circuit boards. The feeding push plate 16 moves to the second colored light 9. When the circuit is in position, the second colored light 9 lights up red. At this time, the color sensor 18 detects the red light, and the two electric push rods 19 drive the two drive boards 20 to extend. Then, the drive boards 20 contact the circuit board in front and send it out for testing. After the board delivery push plate 16 sends out the circuit board, the third colored light 10 lights up green. When the color sensor 18 receives the green light, the two electric push rods 19 reset, and the board delivery push plate 16 retracts. Then, the first colored light 8 lights up red, causing the two drive boards 20 to extend and send out another circuit board. After sending it out, the third colored light 10 lights up, causing the drive boards 20 to be in a retracted state to facilitate the use of the circuit boards below.
[0016] In this embodiment, the circuit board is first placed inside the inner board slot 12, with two circuit boards placed in each slot from both sides, allowing for movement between them. Then, the circuit board holder 11 with the circuit boards placed is placed between the four feeding positioning blocks 7. Simultaneously, a circuit board holder 11 is placed at the position of the receiving positioning block 21 for receiving the boards. A control module is already installed inside the equipment body 1. The hydraulic pump 4 inside the feeding slot 2 is initially in a retracted state. The slot opening of the inner board slot 12 corresponds to the conveying mechanism on the equipment body 1. After the circuit board is sent to the conveying mechanism by the feeding pusher 16, a test is performed to observe whether the circuit board exhibits warping or other issues. Then, the circuit board is conveyed by the conveying mechanism to the inner board slot 12 of the circuit board holder 11 inside the receiving slot 3. The receiving mechanism pushes the circuit board into the inner board slot 12. During feeding, after each layer of circuit boards is fed, the hydraulic pump 4 rises slightly, aligning the next inner board slot 12 with the conveying mechanism. The internal circuit board rack 11 can be configured with push rod parameters for the board receiving mechanism. When receiving the first circuit board at each layer, the circuit board can be sent to the other end of the inner board groove 12. When receiving the second circuit board, the push rod can reduce its movement distance, sending the second circuit board to one end of the inner board groove 12. This allows for the storage of two circuit boards. The two hydraulic actuators 4 operate synchronously, reducing the number of times the circuit board rack 11 needs to be replaced, thus significantly improving testing efficiency.
