Description

Technical Field

[0001] This utility model relates to the field of circuit board testing technology, specifically to a circuit board testing clamping fixture. Background Technology

[0002] After the circuit board is manufactured, it needs to be tested. During testing, a clamping device is needed to hold and fix it in place to facilitate the testing of the circuit board.

[0003] For example, the circuit board clamp and testing device disclosed in the patent document with announcement number CN219715528U includes a base, two clamping structures and two driving components. The base forms a testing space for placing the circuit board to be tested. The clamping structure includes a main body and a pressing component. The two main bodies are respectively located on opposite sides of the testing space. One side of the main body is an abutment surface. The pressing component is rotatably connected to the main body, and the driving component is connected to the pressing component. The driving component presses the circuit board by driving the pressing component to rotate, thereby achieving the clamping of the circuit board.

[0004] Although existing circuit board clamps can clamp circuit boards by pressing with pressing parts, the position of the pressing parts is relatively fixed, so they can only clamp circuit boards of a single size and type. When clamping circuit boards of different sizes and types, different circuit board clamps need to be changed, resulting in low practicality of the circuit board clamps. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a circuit board inspection clamping fixture, which solves the technical problem that the existing circuit board inspection clamping fixture can only achieve the clamping of circuit boards of a single size.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] To address the technical problem that existing circuit board inspection clamping fixtures can only clamp circuit boards of a single size, this utility model provides a circuit board inspection clamping fixture that can clamp circuit boards of any type and size, thereby facilitating the inspection device to inspect the circuit boards.

[0035] like Figure 1 As shown, the circuit board inspection and clamping fixture provided in this embodiment of the present invention includes a base 10, two slide rails 20, two clamping frames 30, a limiting unit 40, and two driving units 50. The base 10 is provided with a clamping position 11 for placing a circuit board. The two slide rails 20 are respectively located on both sides of the clamping position 11. Both ends of the two clamping frames 30 are slidably connected to the two slide rails 20 and can clamp the two sides of the circuit board by sliding. The limiting unit 40 is slidably connected to the two clamping frames 30 and can clamp the other two sides of the circuit board by sliding. The two driving units 50 are respectively connected to the two clamping frames 30 and are used to drive the two clamping frames 30 to slide.

[0036] Specifically, the circuit board inspection and clamping fixture comprises a base 10, two slide rails 20, two clamping frames 30, a limiting unit 40, and two driving units 50. The base 10 has a clamping position 11, where the circuit board to be inspected can be placed. The two slide rails 20 are located on both sides of the clamping position 11, and the two clamping frames 30 are slidably connected to the two slide rails 20. The driving units 50 are connected to the two clamping frames 30 respectively. By driving the two slide rails 20 to move closer to each other and abut against the circuit board, one side of the circuit board can be clamped. The limiting unit 40 is slidably connected to the two clamping frames 30. After the clamping frames 30 clamp the circuit board, the limiting unit 40 slides towards the circuit board to clamp the other two sides of the circuit board. Thus, through the joint cooperation of the clamping frames and the limiting unit 40, the circuit board is clamped and fixed. By sliding the clamping frames and the limiting unit 40, the clamping fixture can clamp circuit boards of any size and type, improving the practicality of the clamping fixture.

[0037] Understandably, this clamping fixture is mainly used for clamping during the circuit board inspection process. It can also be used for clamping other plate-shaped parts similar to circuit boards. When it is applied to the clamping of other plate-shaped parts, its working principle is the same as that of clamping circuit boards.

[0038] In this embodiment, the base 10 is provided with a clamping platform 12, the clamping position 11 is provided on the clamping platform 12, and the two slide rails 20 are located on both sides of the clamping platform 12.

[0039] In one embodiment, a limiting plate 31 is provided on each of the two clamping frames 30 on opposite sides. The limiting plate 31 is located above the clamping position 11 and is used to limit the upper side of the circuit board. Specifically, the limiting plate 31 can limit the upper side of the circuit board, thereby stabilizing the circuit board.

[0040] In one embodiment, the limiting unit 40 includes a plurality of limiting plates 31 and a plurality of locking members 42. Each limiting plate 31 is slidably connected to two clamping frames 30, and the locking members 42 are threadedly connected to the limiting plates 31 for locking the limiting plates 31. Specifically, after the two clamping frames 30 clamp the upper and lower sides of the circuit board, each limiting plate 31 clamps the left and right sides of the circuit board by sliding, thereby stabilizing the circuit board.

[0041] In this embodiment, there are four limiting plates 31 and four locking pieces 42. Two limiting plates 31 are slidably connected to the two ends of one of the clamping frames 30, and the other two limiting plates 31 are slidably connected to the two ends of another clamping frame 30. The clamping frame 30 limits the upper and lower sides of the circuit board by abutting against the upper and lower sides of the circuit board. The four limiting plates 31 clamp the left and right sides of the circuit board and work together with the two clamping frames 30 to stabilize the circuit board.

[0042] Understandably, the drive unit 50 can be any drive component that can drive the clamping frame 30 to slide, such as a motor lead screw module or a hydraulic cylinder.

[0043] In one embodiment, the drive unit 50 includes a drive module 51 and a transmission frame 52. The transmission frame 52 is hinged to the clamping frame 30, and the drive module 51 is connected to the transmission frame 52 for driving the transmission frame 52 to rotate, thereby causing the clamping frame 30 to slide. Specifically, during the clamping of the circuit board, the drive module 51 drives the transmission frame 52 to rotate, causing the end of the transmission frame 52 hinged to the drive frame to move axially, converting the rotation of the transmission frame 52 into the movement of the drive frame, thus enabling more precise control of the drive frame.

[0044] Understandably, the transmission frame 52 can be a rod that is hinged to the drive frame at one end and slidably connected to the column at the other end. The drive module 51 can drive the drive frame by driving the rod to slide against the column.

[0045] In one embodiment, the transmission frame 52 includes a first hinge frame 521 and a second hinge frame 522. The base 10 is provided with a hinge seat 13. The first hinge frame 521 is hinged to the hinge seat 13. One end of the second hinge frame 522 is hinged to the first hinge frame 521, and the other end of the second hinge frame 522 is hinged to the clamping frame 30. The drive module 51 is connected to the first hinge frame 521 and is used to drive the first hinge frame 521 to rotate. Specifically, through the arrangement of the first hinge frame 521 and the second hinge frame 522, during the clamping of the circuit board, the drive module 51 drives the first hinge frame 521 to rotate. The first hinge frame 521 rotates around the hinge seat 13, thereby driving the second hinge frame 522 to rotate, causing the first hinge frame 521 and the second hinge frame 522 to unfold and close, thus driving the transmission frame.

[0046] In one embodiment, two sets of transmission frames 52 are provided, and the two sets of transmission frames 52 are respectively connected to both ends of the clamping frame 30. Specifically, the stable sliding of the drive frame is achieved by the synchronous driving of the two sets of transmission frames 52.

[0047] In one embodiment, to achieve synchronous driving of the two sets of transmission frames 52 and reduce the number of driving components, the driving module 51 includes a driving element 511, a rotating shaft 512, and a transmission rod 513. The base 10 is also provided with a rotating seat 14. The rotating shaft 512 is rotatably connected to the rotating seat 14. One end of the transmission rod 513 is hinged to the transmission frame 52, and the other end of the transmission rod 513 is eccentrically set to and hinged to the rotating shaft 512. The driving element 511 is connected to the rotating shaft 512 and is used to drive the rotating shaft 512 to rotate. Specifically, during the driving of the transmission frame 52, the driving element 511 drives the rotating shaft 512 to rotate. During the rotation of the rotating shaft 512, the transmission rod 513 hinged to it moves. Through the movement of the transmission rod 513, the rotation of the transmission frame 52 is realized, and finally the driving of the transmission frame is achieved.

[0048] In this embodiment, the transmission rod 513 is hinged to the first hinge frame 521 of the transmission frame 52. During the movement of the transmission rod 513, it drives the first hinge frame 521 to rotate, thereby ultimately driving the drive frame.

[0049] In one embodiment, the rotating shaft 512 is provided with an eccentric seat 5121, and the transmission rod 513 is hinged to the eccentric seat 5121. Specifically, the transmission rod 513 is hinged to the eccentric seat 5121 to achieve the eccentric setting of the transmission rod 513 and the hinge connection with the rotating shaft 512.

[0050] Understandably, the drive component 511 can be a motor or other drive component that can drive the rotating shaft 512 to rotate and is directly connected to the rotating shaft 512.

[0051] In one embodiment, the drive element 511 includes a cylinder fixed to the base 10. The piston rod of the cylinder is eccentrically positioned with respect to and hinged to the rotating shaft 512. Specifically, the cylinder drives the piston rod to extend and retract, thereby driving the rotating shaft 512 to reciprocate.

[0052] In one embodiment, the rotating shaft 512 is provided with a sliding seat 5122, and the sliding seat 5122 is provided with a sliding cavity 5123. The piston rod of the cylinder is provided with a sliding head 5111, which is slidably connected to the sliding cavity 5123. Specifically, the cylinder drives the piston rod to extend and retract, causing the sliding head 5111 of the piston rod to slide and rotate inside the sliding cavity 5123, thereby driving the rotating shaft 512 to rotate.

[0053] To better understand this utility model, the following is combined with... Figure 1 The technical solution of this utility model is described in detail as follows: Before the circuit board is inspected, the circuit board to be inspected is first placed on the clamping table 12. Then, the cylinder is started, which drives the rotating shaft 512 to rotate through the piston rod. During the rotation of the rotating shaft 512, the transmission rod 513 is driven to rotate. The rotating rod sequentially drives the first hinge frame 521 and the second hinge frame 522 to rotate, and finally drives the drive frame to slide towards the circuit board until it abuts against the upper and lower sides of the circuit board. Then, the limiting plate 31 is controlled to slide towards the circuit board, so that the limiting plate 31 abuts against the left and right sides of the circuit board. Then, the limiting plate 31 is locked by the locking member 42, and finally the circuit board is clamped. Through the sliding of the clamping frame 30 and the limiting unit 40, the clamping fixture can clamp circuit boards of any size and type, improving the practical performance of the clamping fixture.

[0054] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
