Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to a spot welding device. Background Technology

[0002] Manual circuit board soldering is a precision soldering technique that uses a manual spot soldering pen and control box. During operation, it is necessary to locate the solder joints and adjust the current and time parameters. It is suitable for scenarios such as electronic repair and prototype making, and is characterized by high efficiency and flexibility.

[0003] Existing manual spot welding pens lack an automatic positioning system and rely on visual inspection or simple tools for alignment. However, circuit board components are becoming increasingly miniaturized, and the spacing between solder joints is narrow. They are easily misaligned if not handled carefully. Furthermore, the high temperature generated during the welding process can easily burn the hands. When operators wear heat-resistant gloves to position components, the positioning difficulty will be further increased. Utility Model Content

The surface of the end plate 205 is provided with a plurality of through holes 206. The top surface of the 05 is magnetically connected to a magnetic plate 207. A limiting cylinder 208 is fixedly connected to the top of the magnetic plate 207. A telescopic rod 210 is slidably connected to the inner wall of the limiting cylinder 208. A buffer sleeve 211 is glued and fixed to the outer side of the bottom end of the telescopic rod 210. The bottom end of the telescopic rod 210 is also connected through the magnetic plate 207. A threaded shaft 203 is threaded and inserted into the middle of the top surface of the limiting frame 202. The bottom end of the threaded shaft 203 abuts against the top surface of the rotating plate 204. Figure 2 As shown, the end plate 205 is made of iron and can be magnetically fixed to the magnetic plate 207 with embedded magnets, and the buffer sleeve 211 is made of silicone. A limiting ring 209 is fixedly connected to the middle of the inner wall of the limiting cylinder 208. A push rod 212 is slidably connected through the middle of the inner wall of the limiting ring 209. The top end of the push rod 212 extends above the limiting cylinder 208. A pressure plate 213 is also slidably connected to the top end of the inner wall of the limiting cylinder 208. The middle of the inner wall of the pressure plate 213 is fixedly connected to the outer wall of the push rod 212. A spring 214 is fixedly connected to the bottom surface of the pressure plate 213. The bottom surface of the spring 214 is fixedly connected to the limiting ring 209. The spring 214 is entirely sleeved on the outside of the push rod 212, and the bottom end of the push rod 212 is fixedly connected to the telescopic rod 210. The telescopic rod 210 is aligned with each through hole 206. Figure 5 As shown, the spring 214 has an elastic coefficient of 4 N / mm, and the spring 214 pushes the pressure plate 213 to lift and reset. The welding platform 1 also includes a support platform 101. The lower end and middle of the inner wall of the support platform 101 are each provided with a storage cavity 102. A welding power controller 103 is placed inside the storage cavity 102. An anti-slip pad 109 is adhered and fixed to the middle of the top surface of the support platform 101. The rear end of the top surface of the support platform 101 is rotatably connected to a rotating shaft 201. Figure 1 As shown, the welding power controller 103 can be connected to the welding pen via a wire, and the anti-slip pad 109 is a silicone pad. A threaded shaft 110 is threaded and inserted into the upper back of the support platform 101. The end of the threaded shaft 110 abuts against the surface of the rotating shaft 201. A sliding groove 104 is symmetrically formed on the upper front of the support platform 101. A lead screw 106 is rotatably connected to the inner wall of the support platform 101. The end of the lead screw 106 extends to the outside of the support platform 101 and is fixedly connected to a handwheel 105. Threads with different orientations are provided on both sides of the lead screw 106, and both sides of the lead screw 106 are located inside the sliding groove 104. (The last two sentences are repetitive and can be omitted.) Figure 1 As shown, the slide 104 is positioned in front of the support platform 101 to prevent dust from clogging the thread groove on the surface of the lead screw 106 above the support platform 101.

[0017] The working principle of this utility model: When using the device, place the circuit board to be soldered on the anti-slip pad 109 with the soldering surface facing up. Then rotate the handwheel 105 to drive the lead screw 106 to rotate. The thread on the surface of the lead screw 106 pushes the slider 107 to move along the slide groove 104, thereby clamping and limiting the side of the circuit board through the clamping plate 108. Next, place the component to be soldered on the mounting point on the top surface of the circuit board. Rotate the limiting frame 202 to make the rotating plate 204 coincide with the component to be soldered below. Then tighten the threaded shaft 110 so that its end abuts against the rotating shaft 201 to prevent the rotating shaft 201 from rotating. Then move the rotating plate 204 along the inner side of the limiting frame 202 so that the end plate 205 is above the component to be soldered. Tighten the threaded shaft 203 so that its end abuts against the rotating plate 204, so that the rotating plate 204 cannot slide relative to the limiting frame 202. Insert the telescopic rod 210 into the through hole 206 at a suitable position above the component to be soldered until the magnetic suction plate 207 abuts against and attracts the surface of the end plate 205. When soldering the component, the operator holds the soldering pen with his right hand and presses down the push rod 212 with the other hand to make the telescopic rod 210 fall down and abut against the top of the component through the buffer sleeve 211 to prevent the component from deviating.
