Description

Technical Field

[0001] The utility model relates to the technical field of fixtures, and particularly relates to a one-piece fixture for testing and socketing holes of a single-sided circuit board. Background Art

[0002] After the circuit board is manufactured, it needs to be tested and socketed. There is a fixture on the market that integrates the two functions of testing and socketing. This fixture integrates these two functions, effectively improving work efficiency, reducing operation steps, and lowering costs; and it also reduces the operating equipment and production costs.

[0003] However, this fixture can only process circuit boards of the same specification and cannot meet the processing requirements of circuit boards of different sizes, so its scope of use is limited. Therefore, there is an urgent need for a fixture that can meet the integrated processing of testing and socketing holes for circuit boards of different sizes. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a one-piece fixture for testing and socketing holes of a single-sided circuit board to solve the above deficiencies in the prior art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A one-piece fixture for testing and socketing holes of a single-sided circuit board includes a workbench. There are two positioning components arranged in a cross on the workbench. The positioning component includes an adjusting rod rotatably arranged in the workbench. A double-thread is arranged on the adjusting rod. Two opposite moving rods are threadedly connected to the double-thread. The moving rods are slidably connected to the workbench. A plurality of limiting rods slidably connected to the workbench are fixedly connected to each moving rod. The end of the adjusting rod is fixedly connected to a motor.

[0007] Further, a support plate is slidably connected to the limiting rod and a baffle is fixedly connected. A spring is fixedly arranged between the support plate and the baffle.

[0008] Further, it also includes a testing and socketing component. The testing and socketing component includes a lower fixture plate arranged on the workbench. Testing pins are arranged on the lower fixture plate. There is also a support frame arranged on the workbench. A cylinder is arranged on the support frame. The upper fixture plate is connected to the lower side of the cylinder.

[0009] Further, the testing pin includes a power connection rod connected to the lower fixture plate. A copper head is connected to the end of the power connection rod. A socketing rod is connected to the copper head.

[0010] Further, a socketing groove corresponding to the socketing rod is formed on the upper fixture plate.

[0011] Further, the width of the copper head is greater than the width of the socketing rod.

[0012] In the above technical solution, the beneficial effects of a one-sided circuit board test and hole-setting integrated fixture provided by the present utility model are as follows:

[0013] Through two positioning components arranged in a cross shape, the motor drives the adjusting rod to rotate. The bidirectional thread on the adjusting rod drives the two moving rods to move relatively or away from each other. The moving rods drive the limiting rods to move until the limiting rods abut against the circuit board. By repeating the above operations, abutment against the four side walls of the circuit board can be achieved, so that processing operations can be carried out on different circuit boards, greatly expanding the applicable range of the fixture.

[0014] It should be understood that the foregoing general description and the following detailed description are merely exemplary and explanatory and are not intended to limit the present disclosure.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0024] Please refer to Figures 1-4 , a one-sided circuit board test and hole-setting integrated jig, which includes a workbench 1. There are two positioning components arranged in a cross on the workbench 1. The positioning component includes an adjusting rod 21 rotatably arranged in the workbench 1. A double-thread is arranged on the adjusting rod 21. Two opposite moving rods 22 are threadedly connected to the double-thread. The moving rods 22 are slidably connected to the workbench 1. A plurality of limiting rods 23 slidably connected to the workbench 1 are fixedly connected to each of the moving rods 22. The end of the adjusting rod 21 is fixedly connected to a motor. During the positioning process of the two positioning components, they do not affect each other.

[0025] By providing two cross-shaped positioning components, the motor drives the adjusting rod 21 to rotate. The double-thread on the adjusting rod 21 drives the two moving rods 22 to move relatively or away from each other. The moving rods 22 drive the limiting rods 23 to move until the limiting rods 23 abut against the circuit board. Repeating the above operations can achieve the abutment of the circuit board on each side wall, so that different circuit boards can be processed, greatly expanding the applicable range of the jig.

[0026] Further, a support plate 3 is slidably connected to the limiting rod 23, and a baffle 32 is fixedly connected thereto. A spring 31 is fixedly arranged between the support plate 3 and the baffle 32. The support plate 3 is used to support the circuit board.

[0027] Further, it further includes a test and hole-setting component. The test and hole-setting component includes a lower jig plate 41 arranged on the workbench 1. Test pins 42 are arranged on the lower jig plate 41. A support frame is also arranged on the workbench 1. A cylinder is arranged on the support frame. The upper jig plate 43 is connected to the lower side of the cylinder.

[0028] During the processing, the cylinder drives the upper jig plate 43 to move towards the lower jig plate 41. The upper jig plate 43 abuts against the circuit board and drives the circuit board to move, so that the test pins 42 perform hole-setting and testing operations on the circuit board.

[0029] Further, the test pin 42 includes a power connection rod 51 connected to the lower jig plate 41. A copper head 52 is connected to the end of the power connection rod 51. A hole-setting rod 53 is connected to the copper head 52.

[0030] Furthermore, the upper metallurgical plate 43 is provided with a piercing groove 54 corresponding to the piercing rod 53. The piercing rod 53 extends into the piercing groove 54 after the piercing operation, so that the copper head 52 can detect the electrical performance of the circuit board.

[0031] Furthermore, the width of the copper head 52 is greater than the width of the hole rod 53 .

[0032] Working principle: Place the circuit board on the support plate 3, the motor drives the adjusting rod 21 to rotate, the bidirectional thread on the adjusting rod 21 drives the two moving rods 22 to move relative to or away from each other, and the moving rod 22 drives the limiting rod 23 to move until the limiting rod 23 abuts against the circuit board; repeat the above operation to achieve the abutment of the side walls of the circuit board, thereby completing the positioning of the circuit board; the cylinder drives the upper metallurgical plate 43 to move toward the lower metallurgical plate 41, the upper metallurgical plate 43 abuts against the circuit board and drives the circuit board to move, so that the test needle 42 performs hole-piercing and testing operations on the circuit board.

[0033] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
