Description

Technical Field

[0001] The utility model relates to the field of welding devices, and more particularly to a positioning welding device for circuit boards. Background Art

[0002] A circuit board positioning welding device generally refers to equipment used for accurately positioning and fixing electronic components (such as circuit boards, chips, etc.) and performing welding. These devices are very crucial in the process of electronic manufacturing and assembly, and can ensure the consistency of the accurate position of components and welding quality. When producing circuit boards, a positioning welding device is required to connect and fix the electronic components of the circuit board. The circuit board positioning welding device plays a key role in modern electronic manufacturing, not only affecting product quality, but also directly related to production efficiency and cost control.

[0003] However, most of the current positioning welding devices for circuit boards have the following problems:

[0004] First, for the existing positioning welding devices for circuit boards, when processing circuit boards, most of them play a limiting role by clamping the circuit board left and right. However, circuit boards come in different sizes, and only clamping has poor stability. During the welding process, it is prone to shaking and offset under the influence of external forces, affecting the welding effect, and it is inconvenient to perform convenient front-back and left-right clamping and limiting on the circuit board.

[0005] Second, for the existing positioning welding devices for circuit boards, when welding, the welding torch is mostly fixed in the working position for convenient positioning welding. If the circuit board models are different and the positions for positioning welding are different, it is rather troublesome to adjust the position of the welding torch, and it is inconvenient to perform delicate adjustment of the welding torch.

[0006] Therefore, we make improvements and propose a positioning welding device for circuit boards. Summary of the Utility Model

[0007] The purpose of the utility model is to address the problems that it is inconvenient to perform convenient front-back and left-right clamping and limiting on the circuit board, and at the same time, it is inconvenient to perform delicate adjustment of the welding torch.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] A positioning welding device for circuit boards to improve the above problems.

[0010] Specifically, this application is as follows:

[0011] It includes a protective shell, inside which there is a fixedly connected mounting plate. On the mounting plate, there is a fixedly connected servo motor. The output shaft of the servo motor is fixedly connected to a bidirectional threaded rod, which is rotatably connected inside the mounting plate. A moving block is threadedly connected to the bidirectional threaded rod. A fixing plate is fixedly connected to the moving block. Inside the fixing plate, there is a fixedly connected first spring. The other end of the first spring is fixedly connected to a guiding block. A clamping block is fixedly connected to the guiding block. A clamping plate is arranged on the clamping block. A guiding rod is fixedly connected to the clamping plate, and the guiding rod is slidably connected to the fixing plate in a limited manner. A placing plate is fixedly connected to the mounting plate. A rotating member is rotatably connected to the protective shell. A reciprocating threaded rod is fixedly connected to the rotating member, which is rotatably connected inside the protective shell. A connecting block is threadedly connected to the reciprocating threaded rod. A support frame is fixedly connected to the connecting block. A sliding block is fixedly connected to the support frame, and the sliding block is slidably connected to a sliding rod in a limited manner, and the sliding rod is fixedly connected inside the protective shell. A moving frame is slidably connected to the support frame in a limited manner. A second spring is fixedly connected inside the moving frame. The other end of the second spring is fixedly connected to a limiting plate. A pull rod is fixedly connected to the limiting plate.

[0012] As a preferred technical solution of the present application, the output shaft of the servo motor is fixedly connected to the central part of one end of the bidirectional threaded rod, and the bottom end surface of the moving block is in contact with the inner bottom end surface of the mounting plate.

[0013] As a preferred technical solution of the present application, the moving blocks are symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the moving blocks and the clamping plates correspond to each other through the fixing plates.

[0016] As a preferred technical solution of the present application, a magic tape is fixedly connected between the pull rod and the support frame, and a welding torch is installed on the moving frame. The cross-section of the moving frame is in the shape of a "T".

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

[0018] In the solution of the present application:

[0019] 1. There is a fixed plate; when clamping and limiting the circuit board, the circuit board can be placed on the storage plate, and then the servo motor is turned on to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod can drive the two moving blocks to move inward at the same time. When the moving blocks move, they can drive the fixed plate to move simultaneously.

At the same time, the magic tape on the pull rod can be separated from the magic tape on the support frame. When the moving frame is not blocked, the moving frame can be slid in the support frame to move the welding torch on the moving frame left and right. After the adjustment is completed, the pull rod is released, and under the push of the second spring, the limiting plate and the pull rod are reset. The magic tape on the pull rod can be attached to the magic tape on the support frame, playing a role of connection and fixation, so as to adjust the welding position according to the processing situation of the circuit board.

[0042] Specifically, when the positioning and welding device for the circuit board is in use: Combining Figure 1-6 , when clamping and limiting the circuit board, the circuit board can be placed on the placement plate 12, and then the servo motor 3 on the mounting plate 2 is started to drive the bidirectional threaded rod 4 to rotate. The bidirectional threaded rod 4 can drive the two side moving blocks 5 to move inward at the same time. When the moving blocks 5 move, they can drive the fixed plate 6 to move simultaneously.
