Description

Technical Field

[0001] The present application relates to the technical field of circuit board testing equipment, and in particular to a two-station testing tool. Background Art

[0002] During the circuit board production process, the performance of the circuit boards needs to be tested. Typically, this is done using a multimeter. However, when testing large quantities of circuit boards, this approach is inefficient and can be labor-intensive. Consequently, specialized tooling has emerged for circuit board testing.

[0003] For example, patent application CN118150984A discloses a PCBA test fixture that primarily includes an upper platen and a carrier plate. The upper platen is mounted with test probes, while the carrier plate is used to hold the circuit board. The test probes are connected to a tester, and when the upper platen is moved, the test probes contact the circuit board, allowing for rapid testing of multiple points on the circuit board.

[0004] Although the relevant technology has improved the testing efficiency of circuit boards to a certain extent, the matching degree between the fixture and the staff is low, resulting in the staff's working state being unsaturated during the work process, and the efficiency of circuit board testing needs to be further improved. Utility Model Content

[0005] In order to further improve the efficiency of circuit board testing, this application provides a two-station testing tool.

[0006] The two-station test fixture provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, two sets of fixture bodies are set up on the machine, corresponding to the staff's two hands. During the circuit board testing process, the staff can work with both hands simultaneously, and the two sets of fixture bodies will simultaneously test the circuit board, thereby improving the efficiency of circuit board testing.

[0009] Optionally, the distance between the two fixture bodies is not less than 10 cm and not more than 30 cm.

[0010] By adopting the above technical solution, the distance between the two sets of jig bodies is controlled so that the jig bodies correspond to the arms of the staff, making it convenient for the staff to install the circuit board on the jig bodies.

[0011] Optionally, an adjustment component is provided between the jig body and the machine, and the adjustment component includes two adjustment plates corresponding to the jig body. The adjustment plates are slidably connected to the machine. The sliding adjustment plates can make the two adjustment plates move closer to or away from each other. The jig body is installed on the adjustment plates. The adjustment component also includes a drive component for driving the adjustment plates to move.

[0012] By adopting the above technical solution, the adjustment plate moves, which can drive the two sets of fixture bodies to move closer to or away from each other, so that the fixture can correspond to the arms of workers with different body shapes, thereby improving the applicability of the test tooling.

[0013] Optionally, the driving assembly includes a driving rod rotatably connected to the machine platform and two connecting blocks corresponding to the adjustment plates, the connecting blocks are fixedly connected to the adjustment plates, the driving rod is threadedly connected to the connecting blocks, and rotating the driving rod can drive the connecting blocks to move closer or farther away from each other.

[0014] By adopting the above technical solution, rotating the driving rod can drive the connecting blocks to move closer to or away from each other, and then drive the adjustment plates to move closer to or away from each other, thereby achieving adjustment of the position of the fixture body.

[0015] Optionally, the detection components are arranged in multiple groups at intervals along the horizontal direction.

[0016] By adopting the above technical solution, multiple groups of detection components enable the test tooling to be used by multiple workers to work simultaneously.

[0017] Optionally, a mounting groove is provided on a side surface of the machine platform that is perpendicular to the ground, and the mounting groove is used to place a tester for testing the circuit board.

[0018] By adopting the above technical solution, an installation slot is opened on the machine for placing the tester, which effectively utilizes the space inside the machine and reduces the space occupied by the entire test tooling.

[0019] Optionally, a handle is provided on the tester.

[0020] By adopting the above technical solution, a handle is provided on the tester to facilitate the staff to take the tester out of the installation slot for maintenance.

[0021] Optionally, a baffle is provided on the side of the tester close to the opening of the installation slot, and the baffle abuts against the side where the installation slot is located.

[0022] By adopting the above technical solution, the baffle is used to limit the tester, thereby reducing the situation where the tester as a whole sinks into the installation slot, making it inconvenient to take out the tester.

[0023] Optionally, universal wheels are provided under the machine.

[0024] By adopting the above technical solution, universal wheels are set under the machine to facilitate workers to move the test tooling.

[0025] Optionally, a tightening assembly is further provided on the machine platform, and the tightening assembly includes a threaded rod vertically arranged and threadedly connected to the machine platform.

[0026] By adopting the above technical solution, rotating the threaded rod can move the threaded rod in the vertical direction, so that the threaded rod is pressed against the ground, thereby improving the stability of the test fixture during use.

[0027] In summary, the present application includes the following beneficial technical effects: multiple sets of fixture bodies are set corresponding to the hands of the staff, so that the staff's hands can work synchronously, thereby improving the efficiency of circuit board testing.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a two-station testing tool.

[0034] Reference Figure 1 and Figure 2 The two-station test fixture includes a machine 1 and a detection component 2. The detection component 2 includes two sets of fixture bodies 21 arranged in a horizontal direction. During the circuit board testing process, the staff can work with both hands alternately or simultaneously, thereby improving the efficiency of the circuit board testing.

[0035] Reference Figure 1 and Figure 2The fixture body 21 includes a mounting frame 211, an upper pressing plate 212 vertically slidably connected to the mounting frame 211, and a carrier plate 213 fixedly connected to the mounting frame 211 and located below the upper pressing plate 212 for placing the circuit board. Test probes are mounted on the upper pressing plate 212 and electrically connected to a tester 4 capable of testing the circuit board, thereby enabling testing of the circuit board. A handle is attached to the upper pressing plate 212 to facilitate movement of the upper pressing plate 212.

[0036] Reference Figure 1 and Figure 2 The distance between the two fixture bodies 21 is not less than 10 cm and not more than 30 cm. The two fixture bodies 21 correspond to the arms of the staff, making it convenient for the staff to place the circuit board on the carrier 213.

[0037] Reference Figure 1 and Figure 2 An adjustment component 3 is provided below the mounting frame 211, and the adjustment component 3 is used to drive the fixture body 21 to slide along the direction of its own arrangement, thereby adjusting the distance between the two sets of fixture bodies 21. The position of the fixture body 21 can be adjusted according to the body shape of different workers.

[0038] Reference Figure 1 and Figure 2 The adjustment assembly 3 includes an adjustment plate 31 and a drive assembly 32. The adjustment plate 31 is slidably connected to the machine platform 1, and the fixture body 21 is mounted on the adjustment plate 31, realizing a sliding connection between the fixture body 21 and the machine platform 1. The drive assembly 32 is used to drive the adjustment plate 31 to move. The movement of the adjustment plate 31 can drive the movement of the fixture body 21 to achieve adjustment of the position of the fixture body 21.

[0039] Reference Figure 1 and Figure 2The drive assembly 32 includes a connecting block 322 and a drive rod 321. The drive rod 321 is positioned below the adjustment plate 31 along the sliding direction of the adjustment plate 31. Two connecting blocks 322 are provided, corresponding to the adjustment plate 31, and are welded to the bottom of the adjustment plate 31. A threaded hole is provided on the connecting block 322 at the position corresponding to the drive rod 321, through which the drive rod 321 is inserted. The drive rod 321 is provided with threads with opposite rotations at the positions corresponding to the two connecting blocks 322. Rotation of the drive rod 321 can drive the two connecting blocks 322 to move synchronously toward or away from each other, thereby increasing the speed of position adjustment of the fixture body 21. The drive assembly 32 also includes a driving member 323 for driving the drive rod 321 to rotate. In this embodiment, the driving member 323 is a servo motor. The housing of the servo motor is fixedly connected to the machine platform 1, and the output shaft of the servo motor is coaxially fixedly connected to the drive rod 321. Rotation of the output shaft of the servo motor can automatically rotate the drive rod 321, thereby adjusting the position of the adjustment plate 31.

[0040] Reference Figure 1 and Figure 2 , the detection components 2 can be arranged in multiple groups along the horizontal direction so that the equipment can be used by multiple workers to work simultaneously. In this embodiment, the detection components 2 are arranged in two groups.

[0041] Reference Figure 1 and Figure 3 A mounting groove 43 is provided on the side of the machine 1 perpendicular to the ground, and the tester 4 is installed in the mounting groove 43. The tester 4 can slide out from the opening of the mounting groove 43 to facilitate the staff to inspect and repair the tester 4. A handle 42 is welded to the tester 4 to facilitate the staff to push and pull the tester 4. A baffle 41 is welded on the side of the tester 4 close to the opening of the mounting groove 43. The baffle 41 abuts against the side wall of the mounting groove 43, thereby preventing the tester 4 from continuing to move into the mounting groove 43. At the same time, it can ensure that the side of the tester 4 is flush with the side of the mounting groove 43, making the equipment more beautiful.

[0042] Reference Figure 1 and Figure 3 , a universal wheel 5 is provided at the bottom of the machine 1 to facilitate the movement of the entire equipment. A tightening assembly 6 is provided on the bracket of the universal wheel 5, and the tightening assembly 6 includes a threaded rod 61 and an abutment plate 62. The threaded rod 61 is vertically arranged and threadedly connected to the frame of the universal wheel 5. The abutment plate 62 is a disc-shaped structure, and the abutment plate 62 is horizontally arranged. The abutment plate 62 is welded to the end of the threaded rod 61 close to the ground. Rotating the threaded rod 61 can move the threaded rod 61, and then the abutment plate is pressed against the ground to support and limit the machine 1. When the abutment plate 62 is spaced apart from the ground, the machine 1 can be moved by the universal wheel 5.

[0043] The implementation principle of the two-station test fixture in the embodiment of the present application is: the two sets of fixture bodies 21 are arranged at intervals, so that the staff can place the circuit boards on the two fixture bodies 21 synchronously or alternately, thereby improving the efficiency of circuit board testing.
