It is a substrate used to connect and support electronic components, consisting of one or more layers of insulating and conductive materials. Through pre-designed conductive paths, the circuit board connects electronic components according to circuit principles, thereby realizing the functions of electronic devices. As a core component of electronic devices, its quality and reliability directly affect the performance and stability of the entire system. Therefore, strict static testing of circuit boards is required during production, maintenance, or research and development.

[0003] The shortcomings of the existing technology are as follows: The existing circuit board testing device requires manual placement of each circuit board on the device for testing, which is very inconvenient and inefficient. In addition, the existing testing device cannot fix the position of the circuit board during the testing process, which can easily lead to the circuit board shifting and affect the accuracy of the circuit board test results. Utility Model Content

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The circuit board static testing equipment that facilitates material loading involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] This utility model provides a static testing device for circuit boards that facilitates loading, such as... Figure 1 - Figure 4 As shown, the system includes a workbench 1, with two conveyors 2 equidistantly arranged on one side of the workbench 1 to move the circuit board. A loading / unloading assembly 3 for loading circuit boards is arranged between the two conveyors 2. A positioning assembly 4 for fixing the circuit board is fixedly installed on the top of the workbench 1. Four support rods 5 are fixedly installed in a rectangular array on the top of the loading / unloading assembly 3. A support plate 6 is fixedly installed on the top of the four support rods 5. A cylinder 7 is fixedly installed on the top of the support plate 6. The output end of the cylinder 7 passes through the support plate 6 and is fixedly connected to a test pin plate seat 9. The cylinder 7 pushes the test pin plate seat 9 to move up and down. A test mechanism 11 for static testing of the circuit board is fixedly connected to the bottom of the test pin plate seat 9. The test mechanism 11 performs static testing on the circuit board.

[0023] Further, such as Figure 2 As shown, the loading and unloading assembly 3 includes a carrier plate 32 movably connected between two conveyors 2. An adjustment groove 33 is provided in the middle of the carrier plate 32, and a top block 35 is movably installed in the inner cavity of the adjustment groove 33.

[0024] Further, such as Figure 3 As shown, the positioning component 4 includes a base 41 fixedly installed on the top of the worktable 1, and a limiting groove 43 is formed in the middle of the top of the base 41.

[0025] Further, such as Figure 2As shown, a motor 31 is fixedly installed on one side of the bottom end of the base 41, a push rod 34 is movably connected through one end of the carrier plate 32, a fastening nut 36 is threaded on the outer surface of the push rod 34, a connecting block 37 is fixedly connected to one side of the bottom end of the carrier plate 32, and a transmission rod 38 is fixedly connected to the output end of the motor 31.

[0026] Further, such as Figure 2 As shown, push rod 34 passes through one end of carrier plate 32 and is fixedly connected to one end of top block 35. Pushing push rod 34 adjusts the position of top block 35 in the inner cavity of adjustment groove 33. After the position of top block 35 is adjusted, rotate fastening nut 36 to fix the position of top block 35. Connecting block 37 is movably connected to the outer surface of transmission rod 38. Motor 31 causes transmission rod 38 to rotate. The rotation of transmission rod 38 drives connecting block 37 to move on its outer surface, causing carrier plate 32 to move and perform the circuit board loading operation.

[0027] Further, such as Figure 3 As shown, a limiting plate 42 is fixedly connected to the top of the base 41. The limiting plate 42 restricts the range of the circuit board. Both sides of the inner wall of the limiting plate 42 are fixedly connected to elastic clamps 44. When the circuit board enters the inner side of the limiting plate 42, the elastic clamps 44 make the circuit board automatically move to the correct position.

[0028] Further, such as Figure 4 As shown, the position and size of the carrier plate 32 are adapted to the position and size of the inner cavity of the limiting groove 43. The carrier plate 32 is movably connected to the inner cavity of the limiting groove 43. When the circuit board moves to the top of the carrier plate 32 through one of the conveyors 2, the motor 31 causes the transmission rod 38 to rotate, moving the carrier plate 32 into the inner cavity of the limiting groove 43. Then, the push rod 34 pushes the top block 35 to fix the position of the circuit board. After the test is completed, the motor 31 reverses, causing the carrier plate 32 to be removed from the inner cavity of the limiting groove 43 and returned to the initial position. Finally, the circuit board is removed by another conveyor 2 for the next process.

[0029] Further, such as Figure 1 As shown, a mounting bracket 8 is fixedly installed on the top of the support plate 6, and four guide posts 10 are fixedly installed in a rectangular array on the top of the test pin plate seat 9. The top of the guide posts 10 is fixedly connected to the bottom of the support plate 6.

[0030] The working principle of this utility model is as follows: First, the circuit board is placed directly on the conveyor 2 on one side. The conveyor 2 is started, and the circuit board is moved to the top of the carrier plate 32 by the movement of the conveyor 2. When the circuit board reaches the top of the carrier plate 32, the conveyor 2 stops rotating. Then, the motor 31 is started, which causes the transmission rod 38 to rotate. The rotation of the transmission rod 38 causes the connecting block 37 to move the carrier plate 32 into the inner cavity of the limiting groove 43. During the movement of the carrier plate 32, the circuit board is automatically moved to the accurate position by the elastic clamps 44 on both sides. When the carrier plate 32 is completely moved into the limiting groove 43... After entering the inner cavity, push rod 34 is pushed so that top block 35 fixes the circuit board inside the limiting plate 42. The position of push rod 34 is fixed by rotating fastening nut 36. After the circuit board is fixed inside the limiting plate 42, cylinder 7 is started. Cylinder 7 pushes test pin plate seat 9 up and down. The test mechanism 11 performs static testing on the circuit board. After the test is completed, motor 31 reverses so that carrier plate 32 returns to the initial position. Then conveyor 2 is started. The circuit board is moved by conveyor 2 on the other side so that the circuit board is moved to the next process, completing the automatic loading and unloading operation of the device.

[0031] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships.
