[0001] This utility model relates to the technical field of circuit board testing auxiliary devices, specifically a quick power connection device for circuit board testing. Background Technology

[0002] In today's electronic equipment manufacturing industry, circuit boards are the core components of various electronic devices. Their quality and performance directly affect the operational stability and reliability of the entire electronic device. Therefore, comprehensive and accurate testing of circuit boards has become an indispensable and important part of the production process. During circuit board testing, achieving rapid and stable power connection is a key prerequisite for ensuring the smooth progress of the test.

[0003] Currently, existing power connection devices for circuit board testing have many problems. Common power connection methods are cumbersome and have poor positioning accuracy when positioning circuit boards. Some devices use simple slots or brackets to place circuit boards, but in actual operation, it is difficult to quickly and accurately place the circuit board in the predetermined position, resulting in low power connection efficiency and seriously affecting the test progress. At the same time, due to inaccurate positioning, poor contact between the circuit board and the power connection contacts is prone to occur during the test, causing deviations or even errors in the test results. Therefore, this utility model proposes a quick power connection device for circuit board testing to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4 This utility model provides a technical solution: a quick power connection device for circuit board testing, including a test platform 1 and a controller 11, and further including: a drive component 2, disposed on the test platform 1, which adjusts the height of the wiring component 3 to ensure that the circuit board and the wiring component 3 can be electrically connected; the wiring component 3, disposed at the lower end of the drive component 2, which accurately contacts the test points on the circuit board to establish a stable and reliable electrical connection path, thereby transmitting the electrical signal required for testing to the circuit board; and a positioning component 4, disposed on the test platform 1, which quickly and accurately fixes the position of the circuit board to ensure that the circuit board does not shift or shake during the test.

[0020] Please see Figures 1 to 4 The drive assembly 2 mainly consists of a vertical guide frame 21 and a cylinder 22. The vertical guide frame 21 is detachably installed on the test platform 1. An extension plate is provided on one side of the vertical guide frame 21, and a cylinder 22 is mounted on one side of the extension plate. The output end of the cylinder 22 is connected to a fixed plate 23. The fixed plate 23 is connected through two guide posts 24. The wiring board 32 of the wiring assembly 3 is installed below the fixed plate 23. The lower port of the wiring board 32 has pins arranged according to a certain rule. Under the drive of the wiring board 32, these pins can accurately approach and contact the test points on the circuit board to complete the transmission of electrical signals.

[0021] Please see Figures 1 to 4The wiring assembly 3 also includes a positioning plate 31. The wiring plate 32 is detachably connected to the positioning plate 31 by bolts. The positioning plate 31 is fixedly connected to the bottom of the fixing plate 23 by a pin 33. The pin 33 passes through the pin hole of the positioning plate 31 and the pin hole at the corresponding position of the fixing plate 23 in sequence, thereby firmly assembling the positioning plate 31 under the fixing plate 23, ensuring the relative position stability of each component during the operation of the device, and ensuring the accuracy and reliability of the power connection operation.

[0022] Please see Figures 1 to 4 The positioning component 4 includes a positioning seat 41 mounted on the test platform 1. On both sides of the upper part of the positioning seat 41, there are outwardly protruding rectangular grooves 42. Two sets of first clamping plates 44 are installed within the rectangular grooves 42 at both ends. Each set of first clamping plates 44 is fixedly connected to the inner wall of the rectangular groove 42 by a first spring 43. When the circuit board is placed on the positioning seat 41, because the first clamping plates 44 are fixedly connected to the inner wall of the rectangular groove 42 by the first spring 43, the first spring 43 generates an elastic force. The operator only needs to roughly place the circuit board between the two sets of first clamping plates 44. The rebound force of the first spring 43 will push the first clamping plate 44 to move towards the circuit board, thereby quickly clamping and fixing the circuit board, reducing the time for manual precise alignment and improving positioning efficiency. The rectangular slots 42 at both ends are also provided with first guide rods 47. The first guide rods 47 pass through the first spring 43 and the first clamping plate 44 in sequence, providing guidance for the movement of the first clamping plate 44. Under the action of the first spring 43, the first clamping plate 44 moves along the first guide rods 47, ensuring the accuracy of its movement direction and preventing the first clamping plate 44 from deviating or shaking during the movement.

[0023] Please see Figures 1 to 4 A second clamping plate 45 is provided at both ends of the clamping cavity formed by the first clamping plate 44 at both ends. Each second clamping plate 45 is connected to the clamping cavity of the first clamping plate 44 by means of a second spring 46 and a second guide rod 48. The first clamping plate 44 can achieve initial positioning and clamping of the circuit board, but it may not be able to achieve precise fit for slight size differences or irregular edges of the circuit board. The setting of the second clamping plate 45 provides further fine adjustment. When the circuit board is placed into the positioning component 4, the second clamping plate 45 can automatically adjust its position and angle according to the specific shape and size of the edge of the circuit board under the action of the second spring 46, so as to fit the circuit board more tightly and achieve all-round, high-precision positioning of the circuit board.

[0024] Please see Figures 1 to 4Both the first clamping plate 44 and the second clamping plate 45 are equipped with rubber pads 49 on their clamping end faces. The surface of the circuit board is usually quite fragile. If the circuit board is clamped directly by the hard surface of the clamping plate during the test, scratches can easily be left on its surface, affecting the appearance and performance of the circuit board. Since the rubber pads 49 are soft, they can effectively buffer the contact force between the clamping plate and the circuit board, avoid mechanical damage to the surface of the circuit board by the clamping plate, and ensure the integrity and quality of the circuit board.

[0025] In use, the operator roughly places the circuit board to be tested between the two sets of first clamping plates 44. At this time, the first spring 43 undergoes elastic deformation due to the compression of the circuit board, and its rebound force pushes the first clamping plate 44 along the first guide rod 47 towards the circuit board, achieving initial clamping of the circuit board. After the first clamping plate 44 completes the initial positioning, for minor dimensional differences or irregular edges of the circuit board, the second clamping plate 45, under the action of the second spring 46, automatically adjusts its position and angle along the second guide rod 48 according to the specific shape and size of the circuit board edge, to fit the circuit board more tightly and achieve omnidirectional precision positioning of the circuit board. The controller 11 drives the cylinder 22 to work. The output end of cylinder 22 drives the fixed plate 23 to move up and down along the guide post 24, thereby flexibly adjusting the height of the wiring assembly 3, so that the pins at the lower port of the wiring board 32 are precisely close to the test points on the circuit board to establish an electrical connection. When the wiring board 32 moves to the appropriate position, the pins contact the test points on the circuit board, establishing a stable and reliable electrical connection path. The electrical signal required for the test is transmitted to the circuit board through the wiring board 32 and the pins, and the electrical performance test of the circuit board begins. After the test is completed, the controller 11 controls the cylinder 22 to work, so that the wiring assembly 3 rises back to the initial position, the pins separate from the circuit board, and the staff takes out the tested circuit board from the positioning assembly 4.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
