Technical Field
[0001] This utility model relates to the field of circuit board testing technology, specifically to a circuit board testing device that facilitates material discharge. Background Technology
[0002] In today's booming electronics manufacturing industry, circuit boards, as key basic components of various electronic devices, are being produced in increasing quantities every day, and the requirements for production efficiency and quality are becoming more and more stringent. As an important process to ensure product quality, the performance and ease of operation of the testing equipment directly affect the efficiency and cost of the entire production process.
[0003] After traditional circuit board testing equipment completes the testing, the circuit board is usually placed in the placement slot of the testing mold. Due to the high degree of fit between the placement slot and the circuit board, and the relatively small space of the placement slot, it is difficult for personnel to easily remove the circuit board from the placement slot by hand or simple tools during the unloading process. This problem makes the unloading operation cumbersome and time-consuming, and operators often need to spend a lot of time and energy to handle it, which greatly reduces the overall production efficiency. To address this, we propose a circuit board testing equipment that facilitates unloading. Utility Model Content
[0004] The purpose of this invention is to provide a circuit board testing device that facilitates material discharge, thus solving the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a circuit board testing device for convenient material discharge, comprising a testing platform and a testing pressure plate. A support frame is fixedly installed on the top of the testing platform, and a cylinder is fixedly installed on the top of the support frame. The testing pressure plate is fixedly installed on the output end of the cylinder. A testing mold is installed on the top of the testing platform. A placement groove is opened on the top of the testing mold. A cavity is opened inside the testing mold. A rod hole is opened between the bottom end of the inner wall of the placement groove and the top end of the inner wall of the cavity. A movable plate is slidably connected to the inner wall of the cavity. A push rod is fixedly installed on the top of the movable plate. The push rod moves through the rod hole. Push groove 1 and push groove 2 are respectively opened near the two sides of the movable plate. Push plate 1 and push plate 2 are slidably connected to push groove 1 and push plate 2 respectively. A pull rod is fixedly connected to the front of push plate 1 and push plate 2. A rod groove is opened between the front of the testing mold and the inner wall of the cavity. The pull rod moves through the rod groove.
[0006] Preferably, the opposite sides of the push plate one and the push plate two are both upward-sloping surfaces, and the push plate one and the push plate two are respectively matched with the push groove one and the push groove two. The top of the push rod is fixedly installed with a top pad. By setting the top pad, the push rod can avoid hard contact with the circuit board, reduce wear, and play a certain role in protecting the circuit board.
[0007] Preferably, there are several placement slots. The outer wall of the push rod near the four corners of the detection mold is surrounded by a spring. The spring is fixedly installed between the top of the moving plate and the top of the inner wall of the cavity. By setting the spring, when the moving plate is not under force, the moving plate can automatically move downward under the reset force of the spring.
[0008] Preferably, the front of the testing mold is slidably connected to a limiting frame, and the top of each of the two pull rods is provided with a limiting groove. By setting the limiting frame, the limiting frame can limit the two pull rods, so that the personnel do not need to pull the pull rods all the time, which facilitates the operation of the personnel and further reduces the difficulty of unloading.
[0009] Preferably, a slider is fixedly installed on the back of the limiting frame, and a groove is opened on the front of the detection mold. The slider is slidably connected to the groove. A limiting rod is fixedly installed on the inner wall of the groove. The limiting rod moves through the slider. A second spring is surrounded on the outer wall of the limiting rod. The second spring is fixedly installed between the bottom end of the slider and the bottom end of the inner wall of the groove. By setting the limiting rod, the slider and the second spring can be limited, ensuring the stability of the slider and the second spring under compression during use.
[0010] Preferably, a second magnetic block is fixedly installed at the top of the limiting frame, a fixing plate is fixedly installed on the front of the detection mold, and a first magnetic block is fixedly installed at the bottom of the fixing plate. The first magnetic block and the second magnetic block are magnetically connected. By setting the first magnetic block and the second magnetic block, the limiting frame can be attracted and fixed, thereby improving the stability of the limiting frame when it is not in use.
[0011] This invention provides a circuit board testing device with convenient material discharge. This convenient circuit board testing device has the following advantages:
[0012] (1) The circuit board testing equipment that facilitates material discharge can push out the tested circuit board from the placement slot through the push rod, which makes it easier for personnel to pick up and unload the material, improves work efficiency, and solves the problem that the existing circuit board has a high degree of fit with the placement slot in the mold and the placement slot space is relatively small, which makes it difficult for personnel to easily take out the circuit board from the placement slot by hand or simple tools during the unloading process. The unloading operation becomes cumbersome and time-consuming, which often requires operators to spend more time and energy to handle, greatly reducing the overall production efficiency.
[0013] (2) The circuit board testing equipment that facilitates material discharge can limit the two pull rods by setting a limit frame, so that the personnel do not need to pull the pull rods all the time, which is convenient for personnel to operate and further reduces the difficulty of material discharge. By setting magnetic block one and magnetic block two, the limit frame can be attached and fixed, thereby improving the stability of the limit frame when it is not in use and making it highly practical.

[0022] like Figure 1-4 As shown, this utility model provides a technical solution: a circuit board testing device for convenient material discharge, including a testing platform 1 and a testing pressure plate 3. A support frame 2 is fixedly installed on the top of the testing platform 1, and a cylinder 4 is fixedly installed on the top of the support frame 2. The testing pressure plate 3 is fixedly installed on the output end of the cylinder 4. A testing mold 5 is installed on the top of the testing platform 1. A placement groove 6 is opened on the top of the testing mold 5, and a cavity 8 is opened inside the testing mold 5. A rod hole 7 is opened between the bottom end of the inner wall of the placement groove 6 and the top end of the inner wall of the cavity 8. A movable plate 12 is slidably connected to the inner wall of the cavity 8. A push rod 9 is fixedly installed at the top of the movable plate 12. The push rod 9 moves through the rod hole 7. Push groove 14 and push groove 2 17 are respectively opened on the movable plate 12 near the two sides. Push plate 13 and push plate 2 16 are slidably connected in push groove 14 and push groove 2 17 respectively. Pull rods 15 are fixedly connected to the front of push plate 13 and push plate 2 16. A rod groove 26 is opened between the front of the detection mold 5 and the inner wall of the cavity 8. The pull rod 15 moves through the rod groove 26.
[0023] Among them, the detection pressure plate 3 is the disclosed technology in the announcement number CN222561726U, entitled "A Circuit Board Detection Equipment for Convenient Material Discharge", so it is not described or drawn in detail in this article and the accompanying drawings.
[0024] Furthermore, the opposite sides of push plate 13 and push plate 2 are both upward-sloping surfaces, and push plate 13 and push plate 2 are respectively matched with push groove 14 and push groove 2 17. The top rod 9 is fixedly installed with a top pad 11.
[0025] By setting the top pad 11, the top rod 9 can be prevented from making hard contact with the circuit board, reducing wear and providing a certain degree of protection for the circuit board.
[0026] Furthermore, there are several placement slots 6, and springs 10 are surrounded on the outer wall of the push rods 9 near the four corners of the detection mold 5. The springs 10 are fixedly installed between the top of the moving plate 12 and the top of the inner wall of the cavity 8.
[0027] By setting a spring 10, when the moving plate 12 is not under force, the moving plate 12 can automatically move downward under the reset force of the spring 10.
[0028] Furthermore, the front of the test mold 5 is slidably connected to a limit frame 18, and the top of each of the two pull rods 15 is provided with a limit groove 27;
[0029] By setting a limit frame 18, the limit frame 18 can limit the two pull rods 15, so that the personnel do not need to pull the pull rods 15 all the time, which makes the operation easier and further reduces the difficulty of unloading.
[0030] Furthermore, a slider 20 is fixedly installed on the back of the limiting frame 18, and a groove 19 is opened on the front of the detection mold 5. The slider 20 is slidably connected to the groove 19. A limiting rod 21 is fixedly installed on the inner wall of the groove 19. The limiting rod 21 moves through the slider 20. A spring 22 surrounds the outer wall of the limiting rod 21. The spring 22 is fixedly installed between the bottom end of the slider 20 and the bottom end of the inner wall of the groove 19.
[0031] The limiting rod 21 can limit the movement of the slider 20 and the second spring 22, ensuring the stability of the slider 20 and the second spring 22 during compression.
[0032] Furthermore, a second magnetic block 25 is fixedly installed at the top of the limiting frame 18, a fixing plate 23 is fixedly installed on the front of the detection mold 5, a first magnetic block 24 is fixedly installed at the bottom of the fixing plate 23, and the first magnetic block 24 is magnetically connected to the second magnetic block 25.
[0033] By setting magnetic block 1 24 and magnetic block 25, the limiting frame 18 can be adsorbed and fixed, thereby improving the stability of the limiting frame 18 when it is not in use.
[0034] Specifically, in the above technical solution, the circuit board testing equipment that facilitates material discharge, during use, involves activating cylinder 4 to move the testing platen 3 downwards, causing it to contact a set of circuit boards to be tested on the testing mold 5. This allows the testing platen 3 to perform the testing operation on the circuit boards. After a set of circuit boards has been tested, the two pull rods 15 can be pulled closer together. The two pull rods 15 respectively move push plate one 13 and push plate two 16 closer together. Push plate one 13 and push plate two 16 respectively move... Slot 14 and push slot 2 17 press the moving plate 12 upward, which in turn moves the push rod 9 upward. The push rod 9 then pushes the circuit board in the placement slot 6 upward through the top pad 11, causing the circuit board to detach from the placement slot 6. Then, the limiting frame 18 is pushed downward, causing the magnetic block 25 to detach from the magnetic block 1 24. Under the restoring force of the spring, the slider 20 moves the limiting frame 18 downward, so that both ends of the limiting frame 18 are inserted into the limiting slots 27 at the top of the two pull rods 15, thus limiting and fixing the two pull rods 15. Once the circuit board is ejected from the placement slot 6, the operator can release the two pull rods 15 and remove the circuit board, thus completing the unloading process. This structure allows the ejector rod 9 to push the tested circuit board out of the placement slot 6, facilitating unloading and improving work efficiency. It also addresses the problem that existing circuit boards have a high degree of fit with the placement slot 6 in the mold, and the space in the placement slot 6 is relatively small, making it difficult for operators to easily remove the circuit board from the placement slot 6 by hand or simple tools. This makes unloading cumbersome and time-consuming, requiring operators to spend considerable time and effort, significantly reducing overall production efficiency. By setting a limiting frame 18, the operator can limit the two pull rods 15, eliminating the need for continuous pulling and facilitating operation, further reducing the difficulty of unloading. Furthermore, by setting magnetic blocks 24 and 25, the limiting frame 18 can be attracted and fixed, improving its stability when not in use and enhancing its practicality.
