[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0022] Example 1: As Figure 1 - Figure 7 As shown in the embodiment of the present invention, an electronic component welding device includes two U-shaped plates 1, with their openings facing each other. A first clamping assembly is disposed inside the opening of each U-shaped plate 1. The first clamping assembly includes first clamping plates 11 slidably disposed at the upper and lower ends of the opening of each U-shaped plate 1. A rectangular plate 12 is slidably disposed on one side of each U-shaped plate 1. A first rectangular strip 13 is slidably disposed on the upper end of the rectangular plate 12. A second clamping assembly is disposed at one end of the first rectangular strip 13. A ring 131 is fixedly connected to one end of the first rectangular strip 13. A first circular plate 132 is rotatably disposed in the middle of the ring 131. Second clamping plates 133 are slidably disposed on both sides of the lower end of the first circular plate 132. A second rectangular strip 15 is disposed on one side of each U-shaped plate 1, and the U-shaped plate 1 is rotatably disposed on one side of the second rectangular strip 15. Soldering irons 3 are slidably disposed on both sides of the upper end of each U-shaped plate 1.
[0023] Specifically, when soldering electronic components onto a circuit board, the pins of the electronic components need to be inserted into the holes left on the circuit board, and then the circuit board is flipped. In existing technology, when inserting the pins of electronic components into the circuit board, the electronic components are usually manually fixed before the circuit board is flipped to prevent them from falling off. This flipping process may cause the electronic components to wobble and become unstable, potentially damaging the pins and affecting the soldering effect. When using this soldering equipment, the circuit board is placed between two U-shaped plates 1, positioning it between the first clamping plates 11. Then, the two first clamping plates 11 are driven to slide towards the center within the U-shaped plates 1 until the circuit board is clamped. The electronic components are then placed between the second clamping plates 133, and the two second clamping plates 133 are then driven towards the lower end of the first circular plate 132. The electronic components are clamped by a sliding mechanism in the middle. Then, the first rectangular strip 13 is driven to slide on the upper end of the rectangular plate 12. The first rectangular strip 13 moves the electronic components at the lower end of the first circular plate 132 to the position of the hole in the circuit board through the ring 131. Then, the rectangular plate 12 is driven to slide downward, which in turn moves the first rectangular strip 13 downward. The first rectangular strip 13 moves the lower end of the electronic components downward, so that the pins of the electronic components are inserted into the holes in the circuit board. Then, the U-shaped plate 1 is driven to rotate 180 degrees on one side of the second rectangular strip 15. The U-shaped plate 1 drives the first rectangular strip 13 to rotate through the rectangular plate 12. The first rectangular strip 13 drives the electronic components clamped by the second clamping plate 133 to rotate simultaneously with the circuit board. During the flipping process, the electronic components and the circuit board are kept fixed at all times, and the electronic components are prevented from shaking during rotation. Then, soldering is performed without damaging the pins, which improves the soldering effect.
[0024] like Figure 4 As shown, each of the first rectangular bars 13 has a rectangular block 134 rotatably mounted on both sides of its lower end via a torsion spring, with the lower ends of the rectangular blocks 134 on both sides moving closer to the center.
[0025] Specifically, when the second clamping plate 133 is driven to clamp the electronic component, the pins of the electronic component face downwards. The rectangular block 134 at the lower end of the second clamping plate 133 rotates inwards through the torsion spring. The rectangular block 134 clamps the pins of the electronic component, so that the pins of the electronic component can face vertically downwards, and the pins of the electronic component can be smoothly inserted into the holes left on the circuit board.
[0026] like Figure 3 As shown, a U-shaped strip 14 is fixedly connected to the upper end of the rectangular plate 12, and a first slide table 135 is fixedly connected to one end of the first rectangular strip 13 near the U-shaped strip 14. A first slide rail 136 is fixedly connected to one side of the U-shaped strip 14 corresponding to the first slide table 135. The first slide table 135 is slidably disposed on one side of the first slide rail 136, and both ends of the first slide rail 136 are slidably disposed inside the U-shaped strip 14.
[0027] Specifically, by driving the first slide table 135 to slide on one side of the first slide rail 136, the first slide table 135 drives the first rectangular bar 13 to move. The first rectangular bar 13 drives the electronic components clamped at the lower end of the first circular plate 132 to move left and right through the ring 131. By driving the first slide rail 136 to slide on both sides inside the U-shaped bar 14, the electronic components clamped at the lower end of the first circular plate 132 are moved back and forth, thereby adjusting the position of the electronic components on the upper end of the circuit board.
[0028] like Figure 5 As shown, a first cylindrical rod 153 is rotatably disposed on the side of the second rectangular strip 15 near the U-shaped plate 1. A third rectangular strip 154 is fixedly connected to the end of the first cylindrical rod 153 away from the second rectangular strip 15. The U-shaped plate 1 is fixedly connected to one end of the third rectangular strip 154. A second circular plate 151 is fixedly connected to the outside of the first cylindrical rod 153. The U-shaped strip 14 is slidably disposed on one side of the second circular plate 151.
[0029] like Figure 3 - Figure 5 As shown, a rectangular groove 122 is provided at the lower end of the rectangular plate 12 corresponding to the position of the third rectangular strip 154. The rectangular plate 12 is slidably disposed on the outside of the third rectangular strip 154 through the rectangular groove 122. A cylindrical strip 123 is fixedly connected to the lower end of the rectangular groove 122. The cylindrical strip 123 slides through the middle of the third rectangular strip 154. A rectangular hole 121 is provided at the upper end of the rectangular plate 12. The first rectangular strip 13 is slidably disposed inside the rectangular hole 121.
[0030] like Figure 5 As shown, the second circular plate 151 is fixedly connected to the second slide rail 152 on the side near the U-shaped bar 14, and the U-shaped bar 14 is slidably disposed on one side of the second slide rail 152.
[0031] Specifically, when it is necessary to drive the pins of electronic components to move downwards and insert them into the holes left on the circuit board, the U-shaped bar 14 is driven to move downwards on one side of the second slide rail 152. The U-shaped bar 14 moves downwards outside the third rectangular bar 154 through the rectangular groove 122. The U-shaped bar 14 drives the first rectangular bar 13 in the middle of the rectangular hole 121 to move downwards. The first rectangular bar 13 drives the electronic components held at the lower end of the first circular plate 132 to move downwards through the ring 131, so that the pins of the electronic components can be inserted into the holes left on the circuit board.
[0032] like Figure 1 As shown, a base plate 4 is provided at the lower end of the two second rectangular bars 15, and a second slide table 155 is fixedly connected to the lower end of the second rectangular bars 15. A third slide rail 156 is fixedly connected to the upper end of the base plate 4 at the position corresponding to the second slide table 155. The second slide table 155 is slidably disposed on the upper end of the third slide rail 156.
[0033] Specifically, by driving the second slides 155 on both sides to slide towards the center simultaneously on the upper end of the third slide rail 156, the second slides 155 drive the third rectangular bar 154 to slide towards the center simultaneously via the first cylindrical rod 153, and the third rectangular bar 154 drives the U-shaped plates 1 on both sides to move towards the center simultaneously. The distance between the two U-shaped plates 1 can be adjusted according to the size of the circuit board.
[0034] like Figure 7 As shown, a round tube 31 is fixedly connected to the middle of the soldering iron 3. A second cylindrical rod 32 is rotatably arranged in the middle of the round tube 31. A fourth rectangular strip 33 is fixedly connected to both ends of the second cylindrical rod 32. A rectangular tube 34 is arranged at the lower end of the fourth rectangular strip 33. The fourth rectangular strip 33 is slidably arranged in the rectangular tube 34. A fourth slide table 35 is fixedly connected to the lower end of the rectangular tube 34. A fifth slide rail 36 is fixedly connected to the upper end of the base plate 4 at the position corresponding to the fourth slide table 35. The fourth slide table 35 is slidably arranged on the upper end of the fifth slide rail 36.
[0035] Specifically, by driving the fourth slide table 35 to slide on the upper end of the fifth slide rail 36, the fourth slide table 35 drives the fourth rectangular bar 33 to move through the rectangular tube 34, and the fourth rectangular bar 33 drives the soldering iron 3 to move through the second cylindrical rod 32, thereby adjusting the position of the soldering iron 3 on the upper end of the circuit board. By driving the fourth rectangular bar 33 to slide inside the rectangular tube 34, the fourth rectangular bar 33 drives the soldering iron 3 to move downward through the second cylindrical rod 32, so that the soldering iron 3 is close to the circuit board, and the soldering iron 3 is used to solder the pins on the circuit board.
[0036] Example 2: Figure 6 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: support circular plates 2 are slidably arranged at the four corners of the upper end of the base plate 4.
[0037] like Figure 6 As shown, the lower end of the supporting circular plate 2 is fixedly connected to a support rod 21, and the lower end of the support rod 21 is fixedly connected to a third slide table 22. The upper end of the base plate 4 is fixedly connected to a fourth slide rail 23 corresponding to the position of the third slide table 22. The third slide table 22 is slidably disposed on the upper end of the fourth slide rail 23.
[0038] Specifically, the support circular plate 2 supports the circuit board to prevent the middle of the circuit board from drooping downwards and causing deformation. Since the pins of electronic components need to be inserted into the holes left in the circuit board, the position of the support circular plate 2 needs to be adjusted according to the position of the holes. The third slide 22 is driven to slide on the upper end of the fourth slide rail 23. The third slide 22 drives the support circular plate 2 to move through the support rod 21, thereby adjusting the position of the support circular plate 2.
[0039] Working principle: When using this welding equipment, the circuit board is placed between two U-shaped plates 1, so that the circuit board is located between the first clamping plates 11. Then, the two first clamping plates 11 are driven to slide towards the center inside the U-shaped plates 1 until the circuit board is clamped. Then, the electronic components are placed between the second clamping plates 133. Then, the two second clamping plates 133 are driven to slide towards the center at the lower end of the first circular plate 132 to clamp the electronic components. Then, the first slide table 135 is driven to slide on one side of the first slide rail 136. The first slide table 135 drives the first rectangular bar 13 to move. The first rectangular bar 13 drives the electronic components clamped at the lower end of the first circular plate 132 to move left and right through the ring 131. The first slide rail 136 is driven to slide on both sides inside the U-shaped bar 14, thereby driving the electronic components clamped at the lower end of the first circular plate 132 to move back and forth, thereby adjusting the position of the electronic components on the upper end of the circuit board. Then, by driving the U-shaped bar 14 to move downward on one side of the second slide rail 152, the U-shaped bar 14 moves downward outside the third rectangular bar 154 through the rectangular groove 122. The U-shaped bar 14 drives the first rectangular bar 13 in the middle of the rectangular hole 121 to move downward. The first rectangular bar 13 drives the electronic component clamped at the lower end of the first circular plate 132 to move downward through the ring 131, so that the pins of the electronic component can be inserted into the hole left in the circuit board. Then, the U-shaped plate 1 is driven to rotate 180 degrees on one side of the second rectangular bar 15. The U-shaped plate 1 drives the first rectangular bar 13 to rotate through the rectangular plate 12. The first rectangular bar 13 drives the electronic component clamped by the second clamping plate 133 to rotate simultaneously with the circuit board. During the flipping process, the electronic component and the circuit board remain fixed. The supporting circular plate 2 supports the circuit board to prevent the middle of the circuit board from drooping downwards, which would cause the circuit board to deform. Since the pins of electronic components need to be inserted into the holes left in the circuit board, the position of the supporting circular plate 2 needs to be adjusted according to the position of the holes. The third slide 22 is driven to slide on the upper end of the fourth slide rail 23. The third slide 22 drives the supporting circular plate 2 to move through the support rod 21, thereby adjusting the position of the supporting circular plate 2. By driving the fourth slide table 35 to slide on the upper end of the fifth slide rail 36, the fourth slide table 35 drives the fourth rectangular bar 33 to move through the rectangular tube 34. The fourth rectangular bar 33 drives the soldering iron 3 to move through the second cylindrical rod 32, thereby adjusting the position of the soldering iron 3 on the upper end of the circuit board. By driving the fourth rectangular bar 33 to slide inside the rectangular tube 34, the fourth rectangular bar 33 drives the soldering iron 3 to move downward through the second cylindrical rod 32, so that the soldering iron 3 is close to the circuit board, and the soldering iron 3 is used to solder the pins on the circuit board.
