Description

Technical Field

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

[0002] Circuit boards are the basic structures in electronic devices used to connect and support electronic components. They enable electrical connections and signal transmission between electronic components through pre-designed conductive lines and insulating substrates. During the processing, testing, or repair of circuit boards, it is necessary to position and stabilize them to ensure that they do not shift or deform during the process.

[0003] Announcement No. CN221710151U discloses a circuit board clamp, which addresses the shortcomings of traditional circuit board clamp designs that only support standardized clamping and fixing of circuit boards of a single size. When faced with circuit boards of different sizes, the lack of flexible adjustment structure makes it impossible to stably clamp circuit boards of different sizes, resulting in poor overall compatibility. The clamp improves this by setting a longitudinal slide groove on the top of the worktable and configuring an adapter slider on the bottom of the clamping plate, allowing the clamping plate to be moved and adjusted along the slide groove. This expands the clamping range and improves the clamp's compatibility with circuit boards of multiple sizes.

[0004] However, the surfaces of the horizontal fixing plate and the clamping plate that contact the circuit board are both flat, which can only provide a good clamping effect for circuit boards with regular edges. For circuit boards with irregular contours or rounded transitions, the compatibility between the horizontal fixing plate and the clamping plate and the circuit board is poor and the contact is not stable enough, which affects the clamping effect of the circuit board and results in poor compatibility with complex board shapes. Therefore, a circuit board clamp is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a circuit board clamp with good compatibility. It solves the problem that existing circuit board clamps can only provide good clamping effect for circuit boards with regular edges. For circuit boards with irregular contours or arc transitions, the compatibility between the lateral fixing plate and the clamping plate and the contact surface of the circuit board is poor and the contact is not stable, which affects the clamping effect of the circuit board and results in poor compatibility with complex board shapes.

[0006] To achieve the aforementioned goal of good compatibility, this utility model provides the following technical solution: a circuit board clamp, including a base, a support plate rotatably connected to the surface of the base, two movable mounting plates provided on the surface of the support plate, an angle adjustment component provided between the base and the support plate, and a clamping structure provided on the movable mounting plate;

[0007] The clamping structure includes a support plate and a clamping plate fixedly mounted on the surface of the movable mounting plate. The support plate has a groove extending to the upper surface of the support plate. A spring is fixedly installed inside the groove. A connecting slider located in the groove is fixedly installed at one end of the spring. A clamping post is fixedly installed on the top of the connecting slider. A right-angle slot is opened on the surface of the clamping plate. A semi-circular locking strip is fixedly installed inside the right-angle slot. A locking assembly for fixing the clamping post is provided on the lower surface of the support plate. A driving assembly is provided between the support plate and the movable mounting plate.

[0008] Furthermore, the number of the sliding grooves is multiple and evenly distributed on the surface of the pallet, and the number of the clamping posts is adapted to the number of the sliding grooves.

[0009] Furthermore, a limiting slot is formed on each of the opposite surfaces inside the slide groove, and a limiting protrusion is fixedly installed on each of the opposite surfaces of the connecting slider, which engages with the limiting slot.

[0010] Furthermore, the surface of the clamping post is provided with two annular grooves.

[0011] Furthermore, the angle adjustment component includes a groove formed on the surface of the base, a crossbar slidably installed in the groove, two sleeves rotatably sleeved on the surface of the crossbar, a support rod fixedly installed on the surface of the sleeve, the end of the support rod away from the sleeve being rotatably connected to the lower surface of the support plate, and an adjusting threaded rod threadedly connected to the crossbar being rotatably installed in the groove.

[0012] Furthermore, guide grooves are provided on opposite sides of the interior surface of the groove, and the two ends of the crossbar are respectively located in the two guide grooves.

[0013] Furthermore, the locking assembly includes a locking threaded post fixedly installed on the lower surface of the tray and two connecting slide rods. A locking plate that is threadedly connected to the locking threaded post is slidably sleeved on the surface of the connecting slide rod. Corresponding rectangular holes are opened on the surface of the locking plate and the inner surface of the slide groove. A locking pull rod that passes through the rectangular hole and extends to the lower surface of the tray is fixedly installed on the surface of the connecting slide rod. The diameter of the end of the locking pull rod located on the lower surface of the tray is larger than the width of the rectangular hole. The distance between the locking plate and the opposite side surface of the tray is not less than five centimeters.

[0014] Furthermore, the drive assembly includes a first strip groove formed on the surface of the support plate and two second strip grooves. A lead screw is rotatably installed inside the first strip groove. Threaded sleeves that are threadedly connected to the lead screw are fixedly installed on the lower surfaces of both movable mounting plates. A limit slide rod is fixedly installed inside the second strip groove. Two sliding sleeves that are slidably sleeved with the limit slide rod are fixedly installed on the lower surfaces of both movable mounting plates.

[0015] Furthermore, the lead screw includes a right-hand threaded section and a left-hand threaded section, and the two threaded sleeves are respectively threadedly connected to the right-hand threaded section and the left-hand threaded section of the lead screw.

[0016] Compared with the prior art, the present invention provides a circuit board clamp with the following advantages:

[0017] This circuit board clamp features multiple grooves on the surface of the tray, with springs and clamping posts independently installed in each groove. This creates a multi-point elastic support structure on the tray surface. When clamping circuit boards with curved or irregular edges, each clamping post can stretch the springs and slide along the grooves according to the board's contour, allowing the surface of the clamping post to adaptively fit the edge shape of the circuit board. Combined with the annular grooves on the surface of the clamping posts, this further increases the clamping stability of the circuit board edges, effectively solving the problem of unstable contact in traditional planar clamping structures and improving the clamp's compatibility with complex board shapes.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] Please see Figure 1-6 In this embodiment, a circuit board clamp includes a base 1, a support plate 2 rotatably connected to the surface of the base 1, two movable mounting plates 3 on the surface of the support plate 2, an angle adjustment component 5 between the base 1 and the support plate 2, and a clamping structure 4 on the movable mounting plate 3.

[0027] The clamping structure includes a support plate 41 and a clamping plate 42 fixedly mounted on the surface of the movable mounting plate 3. The support plate 41 has a groove 43 extending to the upper surface of the support plate 41. A spring 44 is fixedly mounted inside the groove 43. A connecting slider 45 located in the groove 43 is fixedly mounted at one end of the spring 44. A clamping post 46 is fixedly mounted on the top of the connecting slider 45. A right-angle slot 47 is opened on the surface of the clamping plate 42. A semi-circular locking strip 48 is fixedly mounted inside the right-angle slot 47. A locking assembly 7 for fixing the clamping post 46 is provided on the lower surface of the support plate 41. A driving assembly 6 is provided between the support plate 2 and the movable mounting plate 3.

[0028] In this embodiment, there are multiple grooves 43 evenly distributed on the surface of the tray 41, and the number of clamping posts 46 is adapted to the number of grooves 43. Multiple clamping support points can be formed on the surface of the tray 41 through multiple clamping posts 46.

[0029] In this embodiment, a limiting slot 431 is provided on each of the opposite surfaces inside the slide groove 43, and a limiting protrusion 451 is fixedly installed on the opposite surface of the connecting slider 45, which is engaged with the limiting slot 431. By setting the limiting slot 431 and the limiting protrusion 451, the clamping column 46 can be effectively prevented from falling out of the slide groove 43.

[0030] In this embodiment, two annular grooves 461 are provided on the surface of the clamping post 46. By providing the annular grooves 461, it is easy for the edge of the circuit board to contact the clamping post 46, and the edge of the circuit board can be prevented from sliding on the surface of the clamping post 46.

[0031] In this embodiment, the angle adjustment component 5 includes a groove 51 formed on the surface of the base 1. A crossbar 52 is slidably installed in the groove 51. Two sleeves 53 are rotatably sleeved on the surface of the crossbar 52. A support rod 54 is fixedly installed on the surface of the sleeve 53. The end of the support rod 54 away from the sleeve 53 is rotatably connected to the lower surface of the support plate 2. An adjusting threaded rod 55 that is threadedly connected to the crossbar 52 is rotatably installed in the groove 51. By setting the angle adjustment component 5, the angle of the clamped circuit board can be adjusted according to the needs, which facilitates the processing of the circuit board.

[0032] In this embodiment, guide grooves 511 are provided on opposite sides of the inner surface of the groove 51, and the two ends of the crossbar 52 are respectively located in the two guide grooves 511, which helps to ensure that the crossbar 52 moves stably in the groove 51.

[0033] In this embodiment, the locking assembly 7 includes a locking threaded post 72 fixedly installed on the lower surface of the support plate 41 and two connecting slide rods 71. The surface of the connecting slide rod 71 is slidably sleeved with a locking plate 73 that is threadedly connected to the locking threaded post 72. The surface of the locking plate 73 and the inner surface of the slide groove 43 are provided with corresponding rectangular holes 74. The surface of the connecting slide rod 45 is fixedly installed with a locking pull rod 75 that passes through the rectangular hole 74 to the lower surface of the support plate 41. The diameter of the end of the locking pull rod 75 located on the lower surface of the support plate 41 is larger than the width of the rectangular hole 74. The distance between the locking plate 73 and the opposite side surface of the support plate 41 is not less than five centimeters. By setting the locking assembly 7, it is convenient to fix the position of the clamping post 46 after clamping.

[0034] In this embodiment, the drive assembly 6 includes a first strip groove 61 formed on the surface of the support plate 2 and two second strip grooves 62. A lead screw 63 is rotatably installed inside the first strip groove 61. Threaded sleeves 64 that are threadedly connected to the lead screw 63 are fixedly installed on the lower surfaces of the two movable mounting plates 3. Limiting slide rods 65 are fixedly installed inside the second strip grooves 62. Two sliding sleeves 66 that are slidably sleeved with the limiting slide rods 65 are fixedly installed on the lower surfaces of the two movable mounting plates 3. The drive assembly facilitates the adjustment of the distance between the two movable mounting plates 3.

[0035] In this embodiment, the lead screw 63 includes a right-hand threaded section and a left-hand threaded section. Two threaded sleeves 64 are threadedly connected to the right-hand threaded section and the left-hand threaded section of the lead screw 63, respectively, so that the two movable mounting plates 3 can move relative to each other or move away from each other at the same time.

[0036] The working principle of the above embodiments is as follows:

[0037] When clamping a circuit board with irregular edge shapes, the circuit board is placed on the support plate 41, and the lead screw 63 is rotated. As the lead screw 63 rotates, it drives two movable mounting plates 3 to move towards or away from each other along the first strip groove 61, achieving synchronous adjustment of the clamping distance. This ensures that the circuit board is always centered on the support plate 2, preventing skewing. When the circuit board contacts the clamping posts 46, each clamping post 46 slides along the slide groove 43 according to the circuit board edge contour and stretches the spring 44. The locking rod 75 moves along the rectangular hole 74, making the surface of the clamping post 46 fit tightly against the edge of the circuit board. The annular groove 461 on the surface of the clamping post 46 increases the contact stability with the edge of the circuit board and prevents slippage. This completes the initial fixing process. After completion, rotating the locking threaded post 72 causes the locking plate 73 to move downward, making the locking plate 73 and the larger diameter end of the locking rod 75 in close contact. This fixes the position of the connecting slider 45 and the clamping post 46. When clamping circuit boards with regular edge shapes, when the edge of the circuit board is placed in the right-angle slot 47, the semi-circular clip 48 can prevent one side of the circuit board from tilting upward. When the adjusting threaded rod 55 drives the crossbar 52 to move along the guide groove 511, the sleeve 53 on the surface of the crossbar 52 is rotatably connected to the lower surface of the support plate 2 through the support rod 54. When the crossbar 52 moves, the support rod 54 pushes the support plate 2 to rotate, thereby adjusting the angle of the support plate 2.

[0038] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.
