Description

Technical Field

[0001] This utility model relates to the field of tinning machine technology, specifically an automatic tinning machine. Background Technology

[0002] Tinning is a common process in electronic component manufacturing. The process involves immersing the terminals or pins of an electronic component in molten solder, allowing solder to deposit onto the terminals or pins. This treatment improves the component's corrosion resistance, oxidation resistance, and solderability, thereby ensuring the long-term stable operation of electronic equipment.

[0003] Currently, when performing soldering operations, electronic components need to be removed from the material tray first, then immersed in flux and molten solder in sequence, and finally placed in the receiving tray. This process is repeated. This soldering method is inefficient and affects the company's production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic tinning machine with high tinning efficiency, which can improve enterprise production efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] An automatic soldering machine includes a processing table. A first servo motor is mounted on the upper surface of the processing table. A base plate is mounted on the end of the output shaft of the first servo motor. A first electric push rod is mounted on the upper surface of the base plate. A top plate is mounted on the telescopic end of the first electric push rod. Four extension plates are coaxially arrayed on the outer surface of the top plate. Mounting rods are provided at the ends of the extension plates, and clamping mechanisms are provided at the bottom of the mounting rods. A first conveyor belt and a second conveyor belt are respectively mounted on adjacent sides of the upper surface of the processing table. Infrared sensors are provided on both the first and second conveyor belts. Flux pools and molten solder pools are respectively provided on the other two sides of the upper surface of the processing table. The first conveyor belt, the second conveyor belt, the flux pool, and the molten solder pool correspond one-to-one with the four clamping mechanisms. A transfer mechanism is provided between the first and second conveyor belts.

[0007] As can be seen, the four clamping mechanisms correspond to the first conveyor belt, the second conveyor belt, the flux pool, and the molten solder pool, respectively. Therefore, when the first electric push rod drives the top plate to descend, it can simultaneously complete the four steps of clamping materials, dipping in flux, dipping in molten solder, and discharging materials, thereby greatly improving the soldering efficiency and the production efficiency of enterprises. Moreover, the whole process is completed automatically, with a high degree of automation.

[0008] Furthermore, the clamping mechanism includes a mounting plate installed at the bottom of the mounting rod. The mounting plate is rotatably connected to a threaded rod with a pair of reverse threads. The mounting plate is provided with two parallel clamping plates, which are respectively mounted on two reverse threads. A second servo motor is mounted on the outer surface of the mounting plate. The end of the output shaft of the second servo motor is connected to the threaded rod. Both sides inside the mounting plate are connected to a first guide rod, and both clamping plates are slidably mounted on the first guide rod.

[0009] When the second servo motor is started, its output shaft drives the threaded rod to rotate. Since both clamping plates are limited by the first guide rod, the reverse thread can drive the two clamping plates to move closer or further apart, thus achieving the purpose of clamping the material.

[0010] Furthermore, the transfer mechanism includes a third conveyor belt, a third servo motor, and a second electric push rod. A bracket is installed on the lower surface of the third conveyor belt, the third servo motor is installed on the upper surface of the processing table, and the second electric push rod is installed at the end of the output shaft of the third servo motor. The end of the telescopic end of the second electric push rod is connected to the bracket.

[0011] After an empty material pallet is conveyed from the first conveyor belt to the third conveyor belt, the second electric push rod is activated to lift the third conveyor belt. Then, the third servo motor rotates 90 degrees to make the conveying direction of the third conveyor belt consistent with that of the second conveyor belt. Next, the second electric push rod drives the third conveyor belt to descend to the same height as the second conveyor belt, and then transfers the empty material pallet above it to the second conveyor belt.

[0012] Furthermore, a third electric push rod is installed on the upper surface of the extension plate, the end of the telescopic end of the third electric push rod is connected to the mounting rod, a linear bearing is installed on the lower surface of the extension plate, a second guide rod is connected to the outer surface of the mounting rod, and the second guide rod is set inside the linear bearing.

[0013] When the third electric push rod is activated, it can drive the mounting rod to move back and forth, thus driving the clamping mechanism to clamp materials at different positions on the material tray, and can place the tinned materials at different positions on the material tray. Through the setting of linear bearings and second guide rods, the limiting and guiding effect on the mounting rod can be improved, making its movement smoother and more precise.

[0014] Furthermore, four third guide rods are coaxially arrayed on the lower surface of the top plate, with the ends of the third guide rods extending to the lower side of the bottom plate.

[0015] The addition of a third guide rod improves the limiting effect on the top plate, enhances the structural strength and stability of the four gripping mechanisms, and increases the gripping accuracy of materials.

[0016] Furthermore, rubber pads are provided on the opposite surfaces of the two clamps, and anti-slip textures are formed on the outer surface of the rubber pads.

[0017] The rubber pads and anti-slip textures not only provide cushioning and protection when gripping materials, preventing surface deformation and damage, but also increase surface friction, improving gripping performance. Attached Figure Description

Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, an automatic soldering machine includes a processing table 100. A first servo motor 101 is mounted on the upper surface of the processing table 100. A base plate 102 is mounted on the end of the output shaft of the first servo motor 101. A first electric push rod 103 is mounted on the upper surface of the base plate 102. A top plate 104 is mounted on the end of the telescopic end of the first electric push rod 103. Four extension plates 110 are coaxially arrayed on the outer surface of the top plate 104. A mounting rod 105 is provided at the end of the extension plate 110. A clamping mechanism 200 is provided at the bottom of the mounting rod 105. A first conveyor belt 106 and a second conveyor belt 107 are respectively installed on the two adjacent sides of the upper surface of the processing table 100. Infrared sensors 111 are installed on both the first conveyor belt 106 and the second conveyor belt 107. Flux pools 108 and molten solder pools 109 are respectively installed on the other two sides of the upper surface of the processing table 100. The first conveyor belt 106, the second conveyor belt 107, the flux pool 108, and the molten solder pool 109 correspond one-to-one with four clamping mechanisms 200. A transfer mechanism 300 is provided between the first conveyor belt 106 and the second conveyor belt 107.

[0026] In operation, workers place a pallet containing materials onto the first conveyor belt 106. The infrared sensor 111 detects the conveying position. Once the material reaches the designated position, the first conveyor belt 106 stops. Then, the first electric push rod 103 starts, causing the top plate 104 to descend, which in turn lowers the clamping mechanism 200 to clamp the material. Next, the first electric push rod 103 raises the top plate 104, and the first servo motor 101 rotates the bottom plate 102 90 degrees. When the first electric push rod 103 lowers the top plate 104 again, material clamping and flux application are achieved. The simultaneous operation, through the above method, enables the four steps of material clamping, flux immersion, molten solder immersion, and material discharge, thereby significantly improving soldering efficiency and enterprise production efficiency. The entire process is completed automatically with a high degree of automation. Furthermore, through the setting of the transfer mechanism 300, the material pallet empty on the first conveyor belt 106 can be transferred to the second conveyor belt 107 to collect the soldered material, achieving the purpose of automatic feeding and receiving. In the early stage, it is only necessary to place an empty material pallet on the second conveyor belt 107 in advance for receiving.

[0027] Specifically, the clamping mechanism 200 includes a mounting plate 201 installed at the bottom of the mounting rod 105. A threaded rod 202 with a pair of reverse threads is rotatably connected inside the mounting plate 201. Two parallel clamping plates 203 are installed inside the mounting plate 201, each mounted on a reverse thread. A second servo motor 204 is mounted on the outer surface of the mounting plate 201. The end of the output shaft of the second servo motor 204 is connected to the threaded rod 202. First guide rods 205 are connected to both sides inside the mounting plate 201, and both clamping plates 203 are slidably mounted on the first guide rods 205. When the second servo motor 204 is started, its output shaft drives the threaded rod 202 to rotate. Since both clamping plates 203 are limited by the first guide rods 205, the reverse threads can cause the two clamping plates 203 to move closer or further apart, achieving the purpose of clamping the material.

[0028] Specifically, the transfer mechanism 300 includes a third conveyor belt 301, a third servo motor 303, and a second electric push rod 304. A bracket 302 is installed on the lower surface of the third conveyor belt 301. The third servo motor 303 is installed on the upper surface of the processing table 100. The second electric push rod 304 is installed at the end of the output shaft of the third servo motor 303. The end of the telescopic end of the second electric push rod 304 is connected to the bracket 302. When an empty material pallet is transported to the third conveyor belt 301 via the first conveyor belt 106, the second electric push rod 304 starts to lift the third conveyor belt 301. Then, the third servo motor 303 rotates 90 degrees so that the conveying direction of the third conveyor belt 301 is consistent with that of the second conveyor belt 107. Then, the second electric push rod 304 drives the third conveyor belt 301 to descend to the same height as the second conveyor belt 107, and then transfers the empty material pallet above it to the second conveyor belt 107.

[0029] Specifically, a third electric push rod 400 is installed on the upper surface of the extension plate 110. The end of the telescopic end of the third electric push rod 400 is connected to the mounting rod 105. A linear bearing 401 is installed on the lower surface of the extension plate 110. A second guide rod 402 is connected to the outer surface of the mounting rod 105, and the second guide rod 402 is located inside the linear bearing 401. When the third electric push rod 400 is activated, it can drive the mounting rod 105 to move back and forth, thus driving the clamping mechanism 200 to clamp materials at different positions on the material tray, and can place the tinned materials at different positions on the material tray. Through the setting of the linear bearing 401 and the second guide rod 402, the limiting and guiding effect on the mounting rod 105 can be improved, making its movement smoother and more precise.

[0030] Specifically, four third guide rods 500 are coaxially arrayed on the lower surface of the top plate 104. The ends of the third guide rods 500 extend to the lower side of the bottom plate 102. The setting of the third guide rods 500 can improve the limiting effect on the top plate 104, improve the structural strength and stability of the four clamping mechanisms 200, and improve the clamping accuracy of materials.

[0031] Specifically, rubber pads are provided on the opposite surfaces of the two clamping plates 203. The outer surface of the rubber pads is provided with anti-slip texture. The rubber pads and anti-slip texture not only provide cushioning protection when clamping materials to prevent deformation and damage to the material surface, but also increase the surface friction and improve the clamping effect.

[0032] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
