Description

Technical Field

[0001] This utility model relates to the field of PCB board welding technology, specifically to a PCB board welding positioning frame. Background Technology

[0002] PCB soldering is an electronic manufacturing process. Its core lies in using heated solder to precisely fix various electronic components onto a printed circuit board and form a reliable electrical connection. In this process, solder plays a crucial role as a medium for conduction and adhesion. Precise soldering ensures stable signal transmission between electronic components and improves the reliability and durability of the entire electronic product.

[0003] During the soldering process, operators typically need to hold the solder wire in one hand and the soldering iron in the other. The wires being soldered usually lack support, and if vibration occurs during the soldering process, the wires may become crooked, resulting in not only aesthetic defects but also incomplete soldering. To address these issues, a PCB board soldering positioning frame is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is as follows: The wires to be welded usually lack support. If vibration occurs during the welding process, the wires may become crooked, which not only results in aesthetic defects, but may also lead to incomplete welding of the wires.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A PCB board welding positioning frame includes a support mechanism, and a clamping mechanism is provided above the support mechanism;

[0009] The adjustment plate is fixedly connected to both ends of the plate, and magnetic components are symmetrically fixedly connected to the top edge of the plate. Each magnetic component is aligned with the adjustment plate in the length direction.

[0010] The adjustment plate has a through-hole in the middle of its surface, and the through-hole is aligned with the adjustment plate in the length direction.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1-5As shown, a PCB board welding positioning frame includes a support mechanism 1, and a clamping mechanism 2 is arranged above the support mechanism 1. The clamping mechanism 2 includes a moving block 201, a lifting block 203 is connected through the inner wall of the middle part of the moving block 201, the top of the lifting block 203 extends to the top of the moving block 201, and a through-hole 204 is opened on the upper surface of the lifting block 203. An extrusion layer 205 is fixedly connected to the inner side wall of the through-hole 204. An adjusting plate 206 is movably installed on the inner wall of the through-hole 204, and the outer side wall of the adjusting plate 206 abuts against the inner side of the extrusion layer 205. End plates 207 are fixedly connected to both ends of the adjusting plate 206, and magnetic suction components 208 are symmetrically fixedly connected to the top edge of the adjusting plate 206. Each magnetic suction component 208 is aligned with the adjusting plate 206 in the length direction. A through-hole 209 is opened in the middle of the surface of the adjusting plate 206, and the through-hole 209 is aligned with the adjusting plate 206 in the length direction. Figure 3 As shown, the extrusion layer 205 is made of rubber. The extrusion layer 205 increases the friction between the inside of the opening 204 and the adjusting plate 206, so that the adjusting plate 206 is not easy to move inside the opening 204, thereby improving the stability of fixing the cable inside the adjusting plate 206.

[0029] A clamping block 210 is movably mounted on the top of the adjusting plate 206. Several clamping blocks 210 are provided, and each clamping block 210 has a magnetic suction component 211 fixedly connected to both sides of its outer wall. The magnetic suction components 211 on both sides are magnetically connected to the sides of the magnetic suction component 208, and the clamping block 210 slides along the inner side of the two magnetic suction components 208. Figure 5 As shown, the magnetic poles of magnetic component 208 and magnetic component 211 are opposite, so magnetic component 211 can be attracted to the side of magnetic component 208, thereby fixing the clamping block 210 and the adjusting plate 206 relative to each other.

[0030] Each lifting block 203 has a groove 212 on one side of its outer wall. A threaded shaft 202 is threadedly connected to the outer wall of the moving block 201 near the groove 212. One end of the threaded shaft 202 passes through the moving block 201 and abuts against the inner side of the groove 212. Figures 3-4 As shown, the end of the threaded shaft 202 abuts against the inner side of the groove 212, thereby keeping the lifting block 203 and the moving block 201 relatively fixed.

[0031] The support mechanism 1 includes a support plate 101. Support feet 102 are fixedly installed on both sides of the bottom surface of the support plate 101. A movable groove 103 is formed on the top of the support plate 101 above each support foot 102. The inner sides of the two movable grooves 103 are slidably connected to movable blocks 201, and the inner sides of the movable grooves 103 are also in movable contact with lifting blocks 203. The bottom end of the lifting blocks 203 extends below the movable grooves 103. A knob 105 is rotatably connected to the center of the front of the support plate 101. The end of the button 105 passes through the support plate 101 and is fixedly connected to the lead screw 106. The other end of the lead screw 106 is rotatably connected to the bottom of the support plate 101. A limiting groove 104 is formed in the middle of the top surface of the support plate 101. Limiting blocks 107 are slidably connected to both sides of the inner wall of the limiting groove 104. A retaining shaft 108 is fixedly connected to the top of each limiting block 107. The bottom of each limiting block 107 is threaded onto both sides of the outer wall of the lead screw 106, and the threads on both sides of the outer wall of the lead screw 106 face opposite directions. Figure 2 As shown, when the lead screw 106 rotates, it drives the limiting block 107 to move along the inner side of the limiting groove 104.

[0032] The working principle of this utility model:

[0033] When the device is in use, the PCB board is placed on the support plate 101. Then, the screw 106 is rotated by the knob 105. The threads on both sides of the screw 106 drive the limit block 107 to move, so that the abutment 108 moves along the inner side of the limit groove 104 and gets closer to each other. Finally, the two abutments 108 are clamped on both sides of the PCB board, and the PCB board and the support plate 101 remain relatively fixed.

[0034] Next, the cable to be soldered is passed through the through-hole 209 from top to bottom. The clamping blocks 210 on both sides of the cable are pushed together, so that the clamping blocks 210 position the cable inside the through-hole 209. Then, the lifting block 203 is pushed, so that the moving block 201 moves along the inside of the moving groove 103. The adjusting plate 206 is pushed, so that it moves along the inside of the through-hole 204, so that the soldering end of the cable can be aligned with the soldering point on the PCB board surface. The threaded shaft 202 is loosened by turning, and the end of the threaded shaft 202 separates from the inside of the abutment groove 212. Thus, the lifting block 203 can move up and down along the inside of the moving block 201, thereby driving the adjusting plate 206 to move closer to the support plate 101. Then, the soldering end of the cable contacts the soldering point on the PCB board surface, which facilitates subsequent soldering.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
