Description

Technical Field

[0001] The utility model relates to the technical field of circuit board soldering equipment, in particular to a circuit board soldering device for controller production. Background Art

[0002] The controller is equipped with a corresponding control circuit board inside. Soldering is required during the circuit board processing. Solder is an important industrial raw material for connecting electronic components in welding circuits. It is a solder with a low melting point, mainly referring to solder made of tin-based alloys. The production method of solder is to first make ingots by melting method and then pressure process them into materials.

[0003] In the prior art, when performing soldering processing on a circuit board, it is usually necessary to place the circuit board on a processing table, clamp the circuit board with a clamping structure, and then use a soldering head to perform soldering operations on the circuit board. However, when the clamping structure clamps the circuit board, two clamping blocks are usually used for relative movement to clamp it between the clamping blocks. This clamping method makes it difficult to clamp and fix the circuit board in the center. At the same time, after the circuit board is soldered, the circuit board is placed on the processing table, and it is difficult for the staff to pick it up and unload it, which makes the operation very inconvenient.

[0004] Therefore, we propose a circuit board soldering device for controller production to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a circuit board soldering device for controller production, so as to solve the problem that the clamping structure in the prior art usually uses two clamping blocks for relative movement when clamping the circuit board, and clamps it between the clamping blocks. This clamping method makes it difficult to clamp and fix the circuit board in the center. At the same time, after the circuit board soldering is completed, the circuit board is placed on the processing table, and it is difficult for the staff to pick it up for unloading.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a circuit board soldering device for controller production, comprising a workbench, a mounting frame fixedly installed at one end of the top surface of the workbench, an electric slide rail fixedly installed at the upper end of the mounting frame, a driving electric cylinder fixedly installed on the moving part of the electric slide rail, and a solder head fixedly installed at the output end of the driving electric cylinder, standing feet fixedly installed at the four corners of the bottom surface of the workbench, a clamping piece installed at the front end of the top surface of the workbench, and a pushing electric cylinder fixedly installed at the front end of the bottom surface of the workbench.

[0007] Preferably, a square top hole is provided in the middle of the top front end of the workbench, linear sliding holes are respectively provided on both sides and ends of the square top hole, a cross inner groove is provided in the inner cavity in the middle of the front end of the workbench, and a through hole is provided in the middle of the front end bottom surface of the workbench.

[0008] Preferably, arc-shaped sliding grooves are respectively provided on the inner walls on both sides of the inner cavity of the linear sliding hole.

[0009] Preferably, the clamping member comprises a cross push frame and clamping blocks respectively slidably inserted at both ends of the top surface of the cross push frame, and an upper top block is fixedly installed at the middle of the top surface of the cross push frame.

[0010] Preferably, top push grooves are respectively provided at both ends and both sides of the top surface of the cross push frame, and inclined push grooves are respectively provided on the inner walls on both sides of the inner cavity of the top push groove.

[0011] Preferably, the clamping block includes a clamping block body and an upper push block fixedly installed in the middle of the bottom surface of the clamping block body, a pair of balls are respectively arranged on the outer walls on both sides of the upper end of the upper push block, and driving slide shafts are respectively fixedly installed on the outer walls on both sides of the lower end of the upper push block, and the driving slide shafts are respectively slidably arranged in the inclined push grooves.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Place the circuit board between the top surface of the workbench and the clamping block, then start the push electric cylinder. The output end of the push electric cylinder will drive the cross push frame to move downward. During the movement of the cross push frame, the clamping block can be driven to move closer and closer relative to each other through the coordinated setting between the driving slide shaft and the inclined push groove, so that the circuit board can be clamped in the center, which improves the center clamping and positioning effect of the circuit board.

[0014] 2. When the electric cylinder drives the cross push frame to move downward, the upper ejector block can be put into the square top hole, so that the circuit board can be placed on the workbench, and the processing stability is good. When the soldering is completed, the output end of the electric cylinder will drive the cross push frame to move upward. After the clamping block contacts the circuit board, the upper ejector block can be used to lift the circuit board, which is convenient for the staff to take the circuit board.

[0015] 3. Through the coordination between the ball and the arc-shaped slide groove, not only the linear sliding restriction of the push-up block in the linear slide hole is achieved, but also the sliding wear and sliding friction of the push-up block in the linear slide hole can be reduced, thereby improving the service life.
