Description

Technical Field

[0001] The utility model belongs to the technical field of electronic equipment manufacturing, and in particular relates to a fixing structure of a sensor circuit board. Background Art

[0002] In the electronics manufacturing industry, the assembly and fixation of circuit boards is one of the key steps to ensure the normal operation of electronic equipment. Traditionally, circuit boards need to be precisely fixed during the assembly process so that electrical components can be soldered on them. In this process, the way the circuit boards are fixed directly affects the soldering quality and the stability and reliability of the final product.

[0003] There are several common problems with existing circuit board fixing structures. First, traditional fixing structures mostly use physical clamping or bonding methods, which are often unable to adapt to circuit boards of various sizes and shapes, resulting in unsatisfactory fixing effects or complicated operations. Second, when the size or shape of the circuit board changes, the fixing structure needs to be replaced or adjusted, which not only increases costs but also prolongs production time. In addition, during the welding process of the existing fixing structure, electrical components are easily displaced due to mechanical vibration or operating errors, thus affecting the welding quality. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a fixing structure for a sensor circuit board, which can be realized. The structure can adapt to circuit boards of different sizes and shapes, and at the same time provide a more stable and reliable fixing effect to improve the accuracy and efficiency of the circuit board welding process.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fixing structure of a sensor circuit board comprises a support frame, wherein the support frame comprises a bottom plate, a first pin-connecting plate is symmetrically fixedly connected to the top of one end of the bottom plate, and a supporting plate is rotatably connected to the inner side of the first pin-connecting plate;

[0007] A placement window is formed through the upper end surface of the support plate, a retaining edge is fixedly connected to the inner bottom edge of the placement window, and a stopper is slidably connected to the retaining edge;

[0008] The upper end surface of the supporting plate is rotatably connected with a lower pressing plate.

[0009] Furthermore, a guide groove is symmetrically formed on the upper end surface of the retaining edge;

[0010] The stopper comprises an adjusting rod, an upper end surface of the adjusting rod is symmetrically penetrated with a through hole, a locking bolt is connected in the through hole, and the locking bolt is used to connect the adjusting rod and the retaining edge together.

[0011] Furthermore, a baffle is fixedly connected to the side of the adjusting rod, and the heights of the baffle and the baffle are on the same horizontal plane.

[0012] Furthermore, the lower pressing plate and the supporting plate are connected via hinges;

[0013] A protective pad is fixedly connected to the bottom of the lower pressing plate.

[0014] Furthermore, the upper end surface of the supporting plate is symmetrically rotatably connected to a locking plate, and the upper end surface of the lower pressing plate is provided with a positioning groove corresponding to the locking plate.

[0015] Furthermore, a first pin connection hole is formed through the side surface of the first pin connection plate, a second pin connection plate is symmetrically fixedly connected to the bottom of one end of the support plate, and a second pin connection hole is formed through the side surface of the second pin connection plate.

[0016] Furthermore, a support column is symmetrically fixedly connected to the upper end surface of the bottom plate, and an inclined baffle is fixedly connected to one side of the bottom plate.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] First, by designing adjustable shifting parts and adjusting rods, the structure allows for quick adaptation to circuit boards of different sizes and shapes. This solves the problem of the prior art being unable to adapt to a variety of circuit board specifications, improves the versatility and flexibility of the fixed structure, and enables the equipment to be adapted to diverse production needs.

[0019] Secondly, the locking bolt is used to stabilize the position of the adjustment rod, combined with the design of the retaining bar and retaining edge to ensure the position stability of the circuit board during the welding process. This design significantly reduces welding defects caused by circuit board shaking or position errors, thereby improving welding quality and product reliability. In addition, this fixing method simplifies the operation steps, improves production efficiency and operation convenience.

[0020] Furthermore, the protective pad included in the lower pressure plate design not only protects the circuit board from mechanical damage, but also evenly distributes the pressure applied to the circuit board to prevent damage to the circuit board or electrical components due to excessive pressure. In addition, the combination of the lower pressure plate and the positioning plate further ensures the accuracy and stability during the welding process and prevents possible misoperation during the operation.

[0021] Finally, through the design of the first pin-jointed plate and the second pin-jointed plate, the support plate can be adjusted or flipped when necessary to meet different operating requirements, increasing the flexibility of equipment use. At the same time, the addition of support columns and inclined baffles on the bottom plate not only improves the stability of the entire structure, but also makes welding operations more convenient and safer.

[0043] See also Figure 4-5 The side of the adjusting rod 31 is fixedly connected with a blocking bar 311, and the height of the blocking bar 311 and the blocking edge 22 are on the same horizontal plane; this design enables the circuit board to be evenly supported at both ends, ensuring the horizontal state of the circuit board during the welding process, thereby improving the welding quality.
