Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a pin welding fixing device. Background Art

[0002] At present, electronic products are used more and more widely in people's daily lives. In many electronic products, pins are needed to transmit signals, especially in some connectors, where the needle pins on the plug need to be inserted into the corresponding receiving holes to transmit signals. These needle pins are often connected to the circuit board inside the plug by welding. In the transmission connection, since the position requirements for the needle pins are not high, ordinary welding fixtures and welding machines can be used for direct welding.

[0003] A pin welding fixture is disclosed in a Chinese utility model patent with announcement number CN218426110U. Although the above-mentioned prior art can fix different circuit boards and achieve the fixing effect, when soldering electronic components on the circuit board, due to the different shapes of some electronic components and the complex appearance, it is more troublesome to solder on the circuit board. The circuit board needs to be rotated so that the pins can be exposed for easy welding. However, since the circuit board is fixed and cannot be rotated, in order to avoid deviation in pin welding, it results in a long waste of welding time and affects the welding efficiency. Therefore, it is necessary to design a pin welding device that can rotate the circuit board to assist in welding. Utility Model Content

[0004] In order to solve the technical problem that a circuit board cannot be rotated to assist in welding when welding pins, the utility model provides a pin welding fixing device.

[0005] The utility model is implemented by the following technical scheme: a pin welding fixing device, including a base plate, one side of the base plate is provided with a fixing component for assisting the pins for welding, the bottom of the fixing component is provided with a rotating component that allows the fixing component to rotate arbitrarily, and both sides of the rotating component are provided with limit components that allow the rotating component to be limited and fixed after moving, and the fixing component includes a fixing plate arranged on one side of the base plate, sliding blocks slidably installed on both sides of the fixing plate, a fixing block with a sliding hole fixedly installed on one side of each sliding block, a connecting rod slidably installed inside each sliding hole, and an elastic band fixedly installed at one end of each connecting rod.

[0006] Through the above technical solution, the circuit board is placed on the fixed plate, and the fixed plate can be rotated at multiple angles by cooperating with the rotating component. After adjusting to a suitable angle, the rotating component can be limited by the limiting component. In this way, welding pins can make the electronic components that were originally more troublesome to weld simple.

[0007] As a further improvement of the above solution, a placement groove is provided on one side of the fixing plate, and a circuit board is provided inside the placement groove.

[0008] Through the above technical solution, the circuit board can be fixed by simply placing it in the placement groove.

[0009] As a further improvement of the above solution, the rotating assembly includes a fixed column arranged on one side of the fixed plate and fixedly installed with the bottom plate, and a first rotating ball rotatably installed at one end of the fixed column, and the first rotating ball is fixedly installed with the bottom of the fixed plate.

[0010] Through the above technical solution, the fixed plate can rotate with the support of the fixed column in cooperation with the first rotating ball.

[0011] As a further improvement of the above scheme, second rotating balls are fixedly installed at the four corners of the fixed plate, and a limiting column is provided on one side of each of the second rotating balls. Each of the second rotating balls rotates in cooperation with an adjacent limiting column, and one end of each of the limiting columns passes through the bottom plate.

[0012] Through the above technical solution, after the fixed plate has finished rotating, the limiting column cooperates with the clamping plate to fix the angle of the fixed plate.

[0013] As a further improvement of the above solution, the limiting assembly includes two clamping plates arranged on both sides of the fixed column and having multiple limiting grooves, and a rubber plate fixedly installed inside each limiting groove, and one side of each rubber plate is in contact with the adjacent limiting column.

[0014] Through the above technical solution, the clamping plate pushes the rubber plate to squeeze the limit column, and the limit column will be fixed due to the friction force.

[0015] As a further improvement of the above scheme, adjustment plates with movable grooves are fixedly installed on both sides of the top of the base plate, and both ends of each of the clamping plates extend into the movable groove of the adjacent adjustment plate. Two bidirectional threaded rods are provided inside the two movable grooves, and both ends of the two bidirectional threaded rods penetrate the adjacent adjustment plates and extend to the outside where rotating blocks are fixedly installed, and the two clamping plates are threadedly matched with the adjacent bidirectional threaded rods.

[0016] Through the above technical solution, the splint can be moved by rotating the bidirectional threaded rod.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model provides a fixing component, a rotating component and a limiting component. When the pins of electronic components are welded on the circuit board, the circuit board is placed on the fixing component, and the electronic components are also fixed by the fixing component, and welding can be carried out. When the welding angle needs to be adjusted, the fixing component is rotated by the rotating component, and after adjusting to a suitable position, the limiting component is used to fix it for welding. This arrangement can not only meet the simple pin welding of the circuit board, but also allow the circuit board to be rotated when complex pin welding is carried out, making complex welding simple.

[0026] Combination Figure 2 and Figure 3 The rotating assembly includes a fixed column 301 arranged on one side of the fixed plate 201 and fixedly installed with the bottom plate 1, and a first rotating ball 302 rotatably installed at one end of the fixed column 301. The first rotating ball 302 is fixedly installed with the bottom of the fixed plate 201, and second rotating balls 6 are fixedly installed at the four corners of the fixed plate 201. A limiting column 7 is arranged on one side of each second rotating ball 6. Each second rotating ball 6 is rotatably matched with the adjacent limiting column 7. One end of each limiting column 7 passes through the bottom plate 1. The fixed plate 201 can rotate under the support of the fixed column 301 by cooperating with the first rotating ball 302. After the fixed plate 201 finishes rotating, the limiting column 7 cooperates with the clamping plate 401 to fix the angle of the fixed plate 201.

[0027] Combination Figure 1 and Figure 3 The limiting assembly includes two clamping plates 401 which are arranged on both sides of the fixed column 301 and have multiple limiting grooves, and a rubber plate 402 fixedly installed inside each limiting groove, one side of each rubber plate 402 is in contact with the adjacent limiting column 7, and adjustment plates 8 with moving grooves are fixedly installed on both sides of the top of the bottom plate 1, both ends of each clamping plate 401 extend into the moving groove of the adjacent adjusting plate 8, and two bidirectional threaded rods 9 are provided inside the two moving grooves, and both ends of the two bidirectional threaded rods 9 penetrate the adjacent adjusting plates 8 and extend to the outside thereof to fix a rotating block 10, and the two clamping plates 401 are threadedly matched with the adjacent bidirectional threaded rods 9, and the clamping plates 401 push the rubber plates 402 to squeeze the limiting column 7, and the limiting column 7 will be fixed due to friction.

[0028] The implementation principle of a pin welding fixing device in the embodiment of the present application is as follows: when soldering the pins of electronic components on the circuit board 5, the circuit board 5 is placed in the placement groove of the fixing plate 201, so that the adapted circuit board 5 will be fixed, and then the electronic component is fixed to one end of the connecting rod 204 using the elastic band 205. The welding position of the electronic component can be adjusted by sliding the connecting rod 204 or the sliding block 202. When the circuit board 5 needs to be rotated to make welding convenient and simple, the fixing plate 201 is moved to cooperate with the first rotating ball 302 and the fixing column 301 to allow the fixing plate 201 to rotate with the circuit board 5, so that the pins that were originally difficult to solder can be made visible and in a position for convenient soldering, thereby fixing When the fixed plate 201 rotates, the second rotating ball 6 cooperates with the limiting column 7 to limit the fixed plate 201 to a certain extent, but it will not hinder the rotation of the fixed plate 201. Then, the two bidirectional threaded rods 9 are rotated to move the clamping plate 401, so that the rubber plate 402 and the limiting column 7 are squeezed. The friction force of the squeezing will fix the limiting column 7. After the limiting column 7 is fixed, the fixed plate 201 will also be fixed and cannot rotate. In this way, welding can be carried out, which simplifies the difficulty of pin welding caused by the complex shape. This setting can not only meet the simple pin welding of the circuit board 5, but also allow the circuit board 5 to rotate when performing complex pin welding, making complex welding simple.

[0029] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
