Technical Field

[0001] This utility model belongs to the field of circuit board clamping technology, and specifically refers to a circuit board clamping device. Background Technology

[0002] As a core component of electronic devices, the development of circuit boards is closely linked to technological advancements. From the early days of mainframe computers, where circuit control boards were bulky and complex, to today's miniaturized and integrated circuits thanks to the rapid development of integrated circuit technology, circuit boards have not only become lighter and more portable but have also significantly improved their performance and reliability. In the current circuit board manufacturing process, clamping devices play a crucial role. They are primarily used to fix the circuit boards, ensuring their stable and accurate positioning throughout the manufacturing, processing, and testing stages. By using clamping devices appropriately, the processing precision and quality of circuit boards can be effectively improved, reducing waste and errors in the production process.

[0003] However, due to factors such as installation space, some circuit boards are designed with irregular shapes. Traditional clamping devices have difficulty clamping irregular circuit boards stably, which affects the subsequent processing accuracy of irregularly shaped circuit boards. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a circuit board clamping device that can stably clamp circuit boards of any shape, has a wide range of applications, and can improve the subsequent processing accuracy of the circuit boards.

[0005] The purpose of this utility model is achieved as follows:

[0006] A circuit board clamping device, comprising:

[0007] The base plate has multiple strip-shaped through holes arranged in parallel.

[0008] Multiple clamping mechanisms are provided at one end of the strip-shaped through hole and spaced apart on both sides of the base plate. Each clamping mechanism includes a fixing rod, a first adjusting block, and a clamping block.

[0009] A height adjustment mechanism is located below the base plate;

[0010] The fixing rod is inserted into the strip-shaped through hole and slidably connected to the strip-shaped through hole. The first adjusting block is sleeved on the fixing rod. The clamping block is disposed on the top of the fixing rod. The first adjusting block is threadedly connected to the fixing rod. A clamping space for clamping the circuit board is formed between the first adjusting block and the clamping block.

[0011] The present invention is further configured such that: the first adjusting block is provided with a clamping protrusion, the clamping protrusion being disposed at one end of the first adjusting block facing the clamping block.

[0012] The present invention is further provided with protective pads above the clamping protrusion and below the clamping block.

[0013] The present invention is further configured such that the clamping mechanism also includes:

[0014] A fixing block is disposed below the base plate, and the fixing block is connected to the fixing rod;

[0016] The present invention is further configured such that: the second adjusting block is provided with a fixing protrusion, the fixing protrusion is provided at one end of the second adjusting block facing the base plate, and the fixing protrusion abuts against the base plate.

[0017] The present invention is further configured such that: a limiting ring is provided on the fixed rod, and the limiting ring is disposed between the first adjusting block and the second adjusting block.

[0018] The present invention is further configured such that the height adjustment mechanism includes:

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 :

[0034] Example 1.

[0035] This embodiment provides a circuit board clamping device, including:

[0036] The base plate 1 has multiple strip-shaped through holes 11 arranged in parallel.

[0037] Multiple clamping mechanisms 2 are provided at one end of the strip-shaped through hole 11 and are spaced apart on both sides of the base plate 1. Each clamping mechanism 2 includes a fixing rod 21, a first adjusting block 22 and a clamping block 23.

[0038] The height adjustment mechanism 3 is located below the base plate 1;

[0039] The fixing rod 21 is inserted into the strip-shaped through hole 11 and slidably connected to the strip-shaped through hole 11. The first adjusting block 22 is sleeved on the fixing rod 21. The clamping block 23 is disposed on the top of the fixing rod 21. The first adjusting block 22 is threadedly connected to the fixing rod 21. A clamping space 27 for clamping the circuit board is formed between the first adjusting block 22 and the clamping block 23.

[0040] like Figure 1-5 As shown, the fixing rod 21 is inserted into the strip-shaped through hole 11 and slidably connected to it, allowing the clamping mechanism 2 to move laterally within the strip-shaped through hole 11. The first adjusting block 22 is threadedly connected to the fixing rod 21, and the first adjusting block 22 cooperates with the clamping block 23 to form a clamping space 27. When it is necessary to clamp a circuit board, the edge of the circuit board can be placed into the clamping space 27, and then the first adjusting block 22 is rotated. The first adjusting block 22 rises and abuts against the lower surface of the circuit board, while the lower surface of the clamping block 23 abuts against the upper surface of the circuit board. The first adjusting block 22 and the clamping block 23 apply longitudinal pressure to the circuit board, completing the clamping of the circuit board edge. The cooperation of multiple clamping mechanisms 2 enhances the stability of the clamping.

[0041] Multiple clamping mechanisms 2 can clamp and fix the edges of circuit boards of any shape at different positions, so that circuit boards of different shapes can be clamped and fixed without changing clamping devices of different specifications, which improves the convenience of clamping, expands the application range of the clamping device, and saves the cost of use.

[0042] Multiple clamping mechanisms 2 are spaced apart on both sides of the base plate 1. The clamping mechanisms 2 are offset at one end of the strip-shaped through hole 11. When it is necessary to clamp the circuit board, the required multiple clamping mechanisms 2 can be directly pushed from both sides of the base plate 1 to the center of the base plate 1 and the circuit board can be quickly clamped, which improves the clamping efficiency.

[0043] The fixing rod 21, the first adjusting block 22, and the clamping block 23 are all made of stainless steel. Stainless steel has good strength and corrosion resistance, and has a long service life.

[0044] Example 2:

[0045] This embodiment provides a circuit board clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] The first adjusting block 22 is provided with a clamping protrusion 221, which is located at the end of the first adjusting block 22 facing the clamping block 23.

[0047] like Figure 3-4 As shown, the clamping protrusion 221 is annular and is integrated with the first adjusting block 22. The clamping protrusion 221 and the clamping block 23 cooperate to increase the clamping area of ​​the clamping mechanism 2 on the circuit board and improve the clamping stability of the clamping mechanism 2.

[0048] At the same time, the clamping protrusion 221 can make it easier to clamp the edge of the circuit board, making the operation more convenient and faster for the user and improving the clamping efficiency of the clamping device.

[0049] Pads 24 are provided above the clamping protrusion 221 and below the clamping block 23.

[0050] like Figure 3-4 As shown, the clamping protrusion 221 and the clamping block 23 are both glued to the protective pad 24. The protective pad 24 can protect the surface of the circuit board when the clamping protrusion 221 and the clamping block 23 are clamping the circuit board, and prevent the circuit board from being damaged due to excessive longitudinal pressure from the clamping protrusion 221 and the clamping block 23.

[0051] Meanwhile, the pad 24 has insulating properties, which can prevent electric shock accidents caused by leakage and short circuit of the circuit board during clamping, thus improving the safety and reliability of the clamping device.

[0052] The pad 24 can be made of rubber or other soft materials. In this invention, silicone is preferred. Silicone has good elasticity and insulation, which can absorb excessive longitudinal pressure, protect the circuit board, ensure the electrical safety of the circuit board, prevent leakage and short circuit of the circuit board from causing electric shock accidents, and protect the safety of users.

[0053] Example 2:

[0054] This embodiment provides a circuit board clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] Clamping mechanism 2 also includes:

[0056] A fixing block 25 is located below the base plate 1, and the fixing block 25 is connected to the fixing rod 21.

[0057] The second adjusting block 26 is located below the first adjusting block 22. The second adjusting block 26 is sleeved on the fixed rod 21 and is threadedly connected to the fixed rod 21.

[0058] like Figure 3-5 As shown, the fixing block 25 is located at the bottom of the fixing rod 21. The fixing block 25 cooperates with the second adjusting block 26 to lock the fixing rod 21 into place with the base plate 1. When the clamping mechanism 2 needs to move, the second adjusting block 26 can be rotated upwards so that the distance between the lower surface of the second adjusting block 26 and the upper surface of the fixing block 25 is greater than the height of the base plate 1. At this time, the fixing rod 21 can move laterally within the strip-shaped through hole 11 to clamp the circuit board. After the clamping mechanism 2 has clamped the circuit board, the second adjusting block 26 can be rotated downwards so that the lower surface of the second adjusting block 26 abuts against the upper surface of the base plate 1, and the upper surface of the fixing block 25 abuts against the lower surface of the base plate 1. The second adjusting block 26 and the fixing block 25 exert longitudinal pressure on the base plate 1, fixing the clamping mechanism 2 on the base plate 1, thereby fixing the position of the circuit board.

[0059] Both the fixing block 25 and the clamping block 23 are provided with fixing holes, and the fixing holes are provided with internal threads. Both ends of the fixing rod 21 are provided with external threads that mate with the internal threads. The fixing holes and the clamping block 23 are threadedly connected to the fixing rod 21.

[0060] The fixing block 25 and the clamping block 23 are detachable. When any part on the clamping mechanism 2 is damaged, the clamping mechanism 2 can be disassembled and the damaged part replaced, which can reduce the maintenance cost of the clamping mechanism 2 and increase its service life.

[0061] The second adjusting block 26 is provided with a fixing protrusion 261, which is located at the end of the second adjusting block 26 facing the base plate 1 and abuts against the base plate 1.

[0062] like Figure 1-4 As shown, the fixing protrusion 261 is annular, and the fixing protrusion 261 and the second adjusting block 26 are integrated into one piece. The fixing protrusion 261 can increase the contact area between the second adjusting block 26 and the base plate 1 when the clamping mechanism 2 is fixed to the base plate 1, improve the stability of the fixation, enhance the fixing effect between the clamping mechanism 2 and the base plate 1, and thus improve the stability of the clamped circuit board.

[0063] Example 3:

[0064] This embodiment provides a circuit board clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0065] A limiting ring 211 is provided on the fixed rod 21, and the limiting ring 211 is located between the first adjusting block 22 and the second adjusting block 26.

[0066] like Figure 3-5 As shown, the limiting ring 211 and the fixing rod 21 are designed as a single unit. The first adjusting block 22 and the second adjusting block 26 are both threadedly connected to the fixing rod 21. The first adjusting block 22 and the second adjusting block 26 are both provided with internal threads, and the fixing rod 21 is provided with matching external threads.

[0067] The limiting ring 211 can limit the movement of the first adjusting block 22 and the second adjusting block 26, preventing the internal threads on the first adjusting block 22 and the second adjusting block 26 from disengaging from the external threads on the fixing rod 21, thus ensuring that the first adjusting block 22 and the second adjusting block 26 maintain a threaded connection when moving on the fixing rod 21. This prevents the first adjusting block 22 and the second adjusting block 26 from sliding against the fixing rod 21, which could damage the internal threads on the first adjusting block 22 and the second adjusting block 26 and affect the service life of the clamping mechanism 2.

[0068] The height adjustment mechanism 3 includes:

[0069] Four lifting cylinders 31 are located below the base plate 1, and the four lifting cylinders 31 are located at the four corners of the base plate 1.

[0070] like Figure 1 As shown, the output end of the lifting cylinder 31 is threadedly connected to the base plate 1. The lifting cylinder 31 can automatically drive the base plate 1 to lift, thereby adjusting the longitudinal position of the circuit board, facilitating subsequent processing, and improving the processing accuracy and efficiency of the circuit board.

[0071] Four lifting cylinders 31 are set at the four corners of the base plate 1. The four lifting cylinders 31 work together to drive the lifting of the base plate 1, which can improve the stability of the device when lifting.

[0072] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
