Description

Technical Field

[0001] The invention belongs to the technical field of electronic component welding, and specifically refers to a welding device for producing electronic components. Background Art

[0002] Welding is an important technology in the assembly of electronic products. It is widely used in the testing, debugging and production of electronic products, and the workload is quite large. The quality of welding will directly affect the quality of the product. In addition to the reasons of components, most of the failures of electronic products are caused by poor welding quality. Therefore, high-quality welding equipment is an important guarantee to ensure that electronic products will not fail for a long time.

[0003] In the prior art, when welding, the electronic component is first inserted into the corresponding soldering hole, and then the electronic component is fixed so that its pin is tightly fitted with the pad to facilitate subsequent welding. However, in the prior art, tweezers are often used to keep the position of the component stable, or glue is used to fix it. When tweezers are used for fixing, only one electronic component can be fixed at a time, and multiple electronic components cannot be fixed at the same time. Fixing with glue has cumbersome steps. In addition, during welding, the welding temperature may reduce the bonding strength of the glue and even cause the electronic component to loosen. The fixation of the electronic component is very important to the quality of the finished circuit board. If the pin is not fixed, the pin may move due to the shaking of the pad, the surface tension of the solder or the slight touch of the soldering iron. If there is a gap or position offset between the component pin and the pad, it may cause poor welding, such as cold soldering or short circuit problems, which will also affect the flatness and aesthetics of the circuit board.

[0004] Therefore, during welding, how to ensure that each pin of the electronic component is accurately aligned with the welding hole and fits tightly with the welding pad to create conditions for high-quality welding has become a technical problem that urgently needs to be solved.

The first sliding hole 56, the second sliding hole 57 and the first sliding shaft 58 and the second sliding shaft 59 limit the moving trajectory of the self-fitting fixing mechanism 5, so that the self-fitting fixing mechanism 5 first moves up and then moves horizontally away from the clamping frame 26, so that the self-fitting fixing mechanism 5 is separated from the clamping frame. 26 is moved up and away, and the clamping mechanism 23 is exposed, and then the welding pad is placed between the four L-shaped clamping plates 29, and the transverse movement mechanism 27 and the longitudinal movement mechanism 28 are started respectively, the transverse movement motor 39 drives the transverse movement bidirectional screw 38 to rotate, and the transverse movement bidirectional screw 38 drives the transverse movement slide 40 to move towards each other, and the transverse movement slide 40 drives the symmetrically arranged longitudinal movement mechanism 28 to move towards each other along the transverse movement slide hole 35 through the transverse movement slider 36, and the longitudinal movement mechanism 28 drives the four L-shaped clamping plates 29 to move towards each other in the transverse direction to clamp and fix the welding pad, the longitudinal movement motor 51 drives the spline shaft 45 to rotate, the spline shaft 45 drives the spline sleeve 47 to rotate, the spline sleeve 47 drives the active bevel gear 49 to rotate, and the active bevel gear 49 drives the longitudinal movement bidirectional screw 38 through the driven bevel gear 50 The rod 41 rotates, and the longitudinal bidirectional screw 41 drives the longitudinal slide 43 to move toward each other, and the longitudinal slide 43 drives the four L-shaped clamps 29 to move toward each other along the longitudinal direction to clamp and fix the pad, so as to clamp and fix the pads of different sizes. After the clamping is completed, the pins of the electronic components are inserted into the corresponding welding holes. After all the electronic components are installed, the swing cylinder 63 is controlled to contract to drive the self-fitting fixing mechanism 5 to reset. The swing cylinder 63 drives the swing gear 62 to rotate through the swing rack 64. The swing gear 62 drives the swing rod 55 to rotate in the direction close to the clamping frame 26 through the swing shaft 60. The swing rod 55 drives the self-fitting fixing mechanism 5 to move along the first sliding hole 56 and the second sliding hole 57 through the driving sliding hole 61 and the driving sliding shaft 53. The hole 56, the second sliding hole 57, the first sliding shaft 58 and the second sliding shaft 59 limit the moving track of the self-fitting fixing mechanism 5, so that the self-fitting fixing mechanism 5 first moves horizontally close to the clamping frame 26 and then moves downward, so that the bottom wall of the fixed cover 10 fits with the upper wall of the clamping frame 26, and then the fixing cylinder 18 is started, and the fixing cylinder 18 drives the lifting plate 11 to move downward, and the lifting plate 11 drives the fitting plate 13 and the elastic fitting fixing capsule 14 to move downward through the fitting spring 12, and the elastic fitting fixing capsule 14 moves downward to fit the pad and the electronic component, and the granular filler 16 automatically avoids the electronic component, and the elastic fitting fixing capsule 14 is deformed to fit the shape of the electronic component, and then the air pump 15 is started, and the air pump 15 extracts the gas in the elastic fitting fixing capsule 14,The granular filler 16 is squeezed and fixed together. At this time, the elastic fitting fixed capsule 14 is not easy to deform. During the air extraction process, the fitting spring 12 always pushes the fitting plate 13 to move downward so that the elastic fitting fixed capsule 14 always keeps in contact with the electronic component, so that the elastic fitting fixed capsule 14 can automatically form a depression according to the shape of the electronic component to self-fit and clamp the electronic component. After the air extraction is completed, the air pump 15 is turned off, and then the flipping component 22 is started. The flipping motor 31 drives the worm 32 to rotate, the worm 32 drives the worm wheel 33 to rotate, and the worm wheel 33 drives the flipping shaft 25 to rotate, so as to facilitate driving the clamping frame 26 and the self-fitting fixing mechanism 5 to rotate and flip around the flipping shaft 25, so that the self-fitting fixing mechanism 5 and the clamping frame 26 rotate to the other side of the flipping shaft 25. At this time, the self-fitting fixing mechanism 5 is fitted with the clamping base plate 20. The clamping frame 26 is located above the self-fitting fixing mechanism 5, and the bottom of the pad is exposed. Then, the pad clamping mechanism 4 is controlled by the electric slide 8 to move along the length direction of the workbench 1 to approach the welding mechanism 2, and the welding mechanism 2 is driven to move along the width direction of the workbench 1 by the electric hanging rail 7. The electric slide 8 and the electric hanging rail 7 cooperate to adjust the welding position. During welding, the electric soldering iron 69 is driven by the welding cylinder 66 to move down close to the pad welding hole, and the two conveying rollers 71 are driven by the wire feeding motor to rotate in opposite directions to realize the transmission of the tin wire. After welding is completed, the flip motor 31 is controlled to rotate in the opposite direction to drive the clamping frame 26 and the self-fitting fixing mechanism 5 to rotate and reset around the flip axis 25, and then the connecting rod moving assembly 9 is started to drive the self-fitting fixing mechanism 5 to move away from above the pad, so as to facilitate the removal of the soldered circuit board.

[0040] When there is no need to flip the pad during the welding process, the flip assembly 22 can be used to drive the clamping frame 26 and the self-fitting fixing mechanism 5 to rotate around the flip axis 25, so that the self-fitting fixing mechanism 5 is at the bottom and the clamping frame 26 is at the top, and then the circuit board can be clamped with the help of the clamping mechanism 23.
