Description

Technical Field

[0001] The present invention relates to the technical field of transformer processing, and in particular to a soldering device for transformer production and processing. Background Art

[0002] Before using the transformer, the ends of the transformer pins need to be immersed in tin liquid to make the connection more stable during subsequent use. In the conventional tinning process, a robot is usually used to clamp the transformer and immerse it in the tin liquid. The tinning work is completed after the tin liquid adheres to the surface of the pins. However, since the transformer pins are relatively thin, they are easily compressed and bent during transportation and storage. The ends of the bent pins will be much higher than other intact pins, resulting in the bent pins being unable to adhere to the tin liquid during tinning at a normal descending height. At the same time, if the bent pins are close to each other, the tin liquid may stick between the two during tinning, thus affecting subsequent use.

[0003] Before the transformer is immersed in tin, the tin liquid will continue to form an oxide layer on the surface due to continuous exposure to the air. The traditional scraping method not only causes waste of tin liquid, but the residual oxide layer also increases the manual cleaning cost. Summary of the Invention

[0004] In order to overcome the shortcomings of incomplete tinning caused by bent pins, adjacent pins are prone to adhesion of tin liquid, affecting subsequent use, and long-term exposure of tin liquid to the air, which is prone to oxidation and causes waste, and conventional scraping increases manual cleaning costs, the present invention provides a soldering device for transformer production and processing.

[0007] Preferably, a pressure plate is also included; the lower side of the electric clamp is connected to a pressure plate to prevent the transformer from being placed unstable.

[0009] Preferably, the lower sides of the two clamping blocks are both provided with inclined surfaces, and the two inclined surfaces are opposite to each other and inclined in an eight-shaped shape.

[0010] Preferably, the relative and figure-eight inclined surfaces of the block are all smooth.

[0011] Preferably, a rotating plate is further included; a plurality of rotating plates are connected to the upper side of the tin liquid box to seal the tin liquid box and reduce the oxidation of the tin liquid; and the rotating shaft of each rotating plate is connected to a motor.

[0013] Preferably, each rotating plate surface is coated with an anti-stick coating.

[0015] The beneficial effects of the present invention are as follows: the present invention realizes straightening the bent pins through the clamping plate and the electric clamping claw, so that no matter which direction the pins are bent, they can be straightened for tin immersion, ensuring that each pin is covered with tin liquid; The pressure plate first contacts the upper side of the transformer and cooperates with the discharge box to form a two-way clamping, ensuring that the transformer does not move during the clamping process; The inclined surfaces on the bottom of all the clamping blocks form an eight-shaped shape, guiding the two to move gradually toward the middle.

DETAILED DESCRIPTION

[0020] The moving component includes a slide rail 101, an electric slider 102 and an electric push rod 103; two slide rails 101 are fixedly connected to the operating table 1; an electric slider 102 is slidably connected to each slide rail 101; two electric push rods 103 are fixedly connected to the two electric sliders 102 through a connecting frame; the telescopic ends of the two electric push rods 103 are fixedly connected to the electric gripper 104.

[0021] It also includes a pressing plate 105; a pressing plate 105 is connected to the lower side of the electric gripper 104.

[0022] It also includes an air bag 106 and an air pipe 107; an air bag 106 is fixedly connected between the fixed portion of the electric gripper 104 and the pressing plate 105; an air cavity 10401 is provided in the claw portion of the electric gripper 104; an air pipe 107 is connected to each air bag 106; one end of each air pipe 107 away from the air bag 106 is connected to the corresponding air cavity 10401.

[0023] Inclined surfaces are provided on the lower sides of the two clamping blocks 108, and the two inclined surfaces are opposite and inclined in a V-shaped manner.

[0024] The inclined surfaces of the clamping blocks 108 that are opposite and inclined in a V-shaped manner are both set to be smooth, preventing the clamping blocks 108 from generating excessive frictional force with the transformer and avoiding abrasion of the surface of the transformer.

[0025] When tinning the transformer, the worker first stacks the transformers as Figure 1As shown, they are neatly placed on the discharge box 2, and then the electric slider 102 is controlled to slide forward on the slide rail 101, driving the connecting frame and the electric push rod 103 on the electric slider 102 to move synchronously. When the electric clamping claw 104 at the end of the electric push rod 103 moves to just above the discharge box 2, the electric slider 102 stops sliding. At this time, the electric push rod 103 is controlled to extend downward, so that the electric clamping claw 104 drops to the transformer position and clamps it. After the clamping is completed, the electric slider 102 continues to move, thereby driving the transformer to move just above the tin liquid box 3. Finally, the electric push rod 103 is extended downward again to immerse the pins of the transformer in the tin liquid to complete the tin dipping operation.

[0026] Combine Figure 4 As shown, in the process of tinning the transformer pins, the transformer is easily compressed during transportation and storage, causing the pins to bend. If the bent pins are close to each other, the tin liquid may stick to each other during tinning, thus affecting subsequent use. At the same time, the bent pins are much higher than other intact pins because their ends are much higher than other intact pins, resulting in the bent pins being unable to adhere to the tin liquid when tinning at a normal lowering height. To solve this problem, when the electric clamp 104 moves to above the discharge box 2, the electric push rod 103 is first started to extend downward, so that the electric clamp 104 is close to the transformer placed on the discharge box 2. As the electric clamp 104 continues to move downward, the electric clamp 104 drives the clamping block 108 to press between the two clamps 5, and uses the guide part 10801 to push the two clamps 5 toward the separated side, that is, the clamp 5 is close to the transformer pin position, thereby stretching the spring between the clamp 5 and the first slide 4. At the same time, the electric clamp 104 is controlled to synchronously approach the transformer pin. It should be noted that: in combination with Figure 4 Figure 6 As shown, since the splint 5 and the electric clamp 104 are both facing the connection between the pin and the transformer, it is difficult for this position to undergo large bending deformation. When the splint 5 and the electric clamp 104 are both attached to the pin, all the semicircular grooves on the splint 5 and all the arc grooves on the electric clamp 104 correspond to each other to cover each pin. At this time, the electric push rod 103 is controlled to move downward. At this time, the two splints 5 are located on the lower side of the extrusion part 10802, and then, driven by the extrusion part 10802, the first slide 4 and the splint 5 are pushed downward together, and then the spring between the first slide 4 and the discharge box 2 is squeezed, so that the splint 5 and the electric clamp 104 are pulled downward along the pin together, that is, no matter which direction the pin bends, the bent pin can be straightened again by the splint 5 and the electric clamp 104 to ensure that each pin is attached with tin liquid.

[0027] During the tinning process of the transformer pins, in order to ensure good adhesion of the tin liquid, it is usually necessary to pre-polish the pin surface to remove the oxide layer. This oxide layer will hinder the uniform spreading of the tin liquid on the pin surface. Therefore, when the splint 5 and the electric clamp 104 move downward along the pin, the sandpaper on the splint 5 and the electric clamp 104 is used to polish the pin surface, and then the transformer is driven to be immersed in the tin liquid for tinning, so that the tin liquid adheres more evenly to each pin.

[0028] When the clamping plate 5 and the electric clamping jaws 104 are close to the transformer for pin grinding, since the transformer is only manually stacked on the discharge box 2, the placement is not stable enough, which causes the transformer to easily shift or even fall out of the box during the grinding and clamping process. For this reason, when the electric clamping jaws 104 move down and approach the transformer, the pressing plate 105 first contacts the upper side of the transformer and cooperates with the discharge box 2 to form an upper and lower bidirectional clamping. As the electric clamping jaws 104 continue to move down, the airbag 106 is compressed and deformed, so that the pressing plate 105 continues to apply a stable fitting pressure to ensure that the transformer pins do not shift during the grinding process. When the electric clamping jaws 104 finally fit the transformer pins, it drives the transformer to perform tin immersion. During this process, the pressing plate 105 provides a pre-clamping function before the electric clamping jaws 104 are fully clamped, effectively preventing the transformer from shifting or falling off during the grinding or clamping stage, thereby enhancing the adaptability and stability of the device.

[0029] Combine Figure 3 As shown, it is also taken into consideration that, through the two opposing and eight-shaped inclined surfaces on the lower sides of the two clamping blocks 108, when the clamping block 108 moves down and approaches the transformer, its inclined surfaces act on the leftmost and rightmost transformers respectively, guiding the two to move gradually toward the middle. As the clamping block 108 continues to press down, the adjacent transformers are tightly fitted under the guiding action. Finally, through the coordinated clamping of the discharge box 2, the pressure plate 105 and the clamping block 108, a composite constraint in the up and down and left and right directions is applied to the transformer. This structure effectively suppresses the displacement of the transformer during the pin grinding and correction process, and significantly improves the positioning stability of the transformer on the discharge box 2.

[0030] When using the sandpaper on the splint 5 and the electric clamp 104 to polish the pins, due to the flexibility of the sandpaper material itself, although it can fit the pin surface, if there is a lack of continuous positive pressure, the efficiency of removing the oxide layer will be reduced. For this reason, after the splint 5 and the electric clamp 104 synchronously abut the pin surface, the continuous downward movement of the electric clamp 104 forces the airbag 106 to be compressed and deformed, and the internal gas is introduced into the air cavity 10401 through the air pipe 107, forming a progressive pressurization environment. The air pressure pushes the sandpaper of the electric clamp 104 to generate a centripetal pressing force, and the semicircular groove structure of the splint 5 constrains the deformation of the corresponding sandpaper, so that the pin is accurately clamped between the two frosted surfaces, thereby achieving efficient polishing and improving the device. The polishing effect of the pins, further, when the pins are broken or damaged, this method can also be used to detect transformers with poor quality. After the subsequent tinning is completed, workers only need to observe whether the pins are intact to remove the transformers with poor quality. Furthermore, after adding sandpaper to the electric clamp 104, the limiting part 10402 can still cooperate with the splint 5 to complete the pin rigidity correction task, effectively overcoming the limitations of soft abrasives in hard pin shaping.

[0031] Example 2: Based on Example 1, Figure 1 、 Figure 7 and Figure 8 As shown, a rotating plate 201 is also included; two rotating plates 201 are connected to the upper side of the tin liquid box 3; and the rotating shaft of each rotating plate 201 is connected to a motor.

[0032] It also includes a connecting plate 202, a steel rope 203 and a second slide 204; a connecting plate 202 is fixedly connected to the middle of the upper side of the tin liquid box 3 in a horizontal manner, the connecting plate 202 is located between the rotating plates 201 and works together with the rotating plates 201 to exert an isolation effect; two second slides 204 are slidingly connected inside the connecting plate 202; a number of steel ropes 203 are fixedly connected to the back sides of the two second slides 204; each steel rope 203 is fixedly connected to the corresponding rotating plate 201 at one end away from the connecting plate 202, and the steel rope 203 is located between the pins of the transformer.

[0033] The surface of each rotating plate 201 is coated with an anti-adhesion coating to reduce the phenomenon of tin liquid adhering to the rotating plate 201 and avoid wasting excess tin liquid.

[0034] The diameter of each steel rope 203 is smaller than the transformer pin spacing.

[0035] Before the transformer is immersed in the tin liquid box 3 for tin dipping, the tin liquid in the tin liquid box 3 is continuously exposed to the air, and an oxide layer will continuously form on the surface. The traditional scraping method not only causes waste of tin liquid, but also the residual oxide layer increases the cost of manual cleaning. Therefore, in the non-operating state, the two rotating plates 201 (such as Figure 7As shown in the figure, the rotating plate 201 and the connecting plate 202 cooperate to achieve a sealed isolation of the upper part of the tin liquid box 3. When tinning is required, the motor reverses and drives the rotating plate 201 to rotate upward to open, exposing the working surface of the tin liquid. This design significantly reduces the oxidation rate of the tin liquid, reduces the loss of raw materials and simplifies subsequent maintenance. Furthermore, the opening action of the rotating plate 201 synchronously pulls one end of the steel rope 203, and then the other end of the steel rope 203 pulls the two second slides 204 away from each other and toward the end of the connecting plate 202. The positions of the steel ropes 203 connected to the same connecting plate 202 and the spacing between them are pre-designed. During the opening process, the steel ropes 203 are precisely positioned in the gaps between adjacent pins. After the tinning process is completed, the electric push rod 103 drives the electric clamp 104 to move the transformer upward, and each steel rope 203 moves downward along the pin gap. By utilizing its thin diameter of 1 to 2 mm, which is smaller than the pin spacing of the transformer, it can effectively separate the adhered tin liquid and break the bridging phenomenon between adjacent pins caused by the adhered tin liquid. In addition, due to its small cross-sectional area, only a trace amount of residual tin is attached, ensuring that there will be no secondary contamination of the pins after multiple operations. This integrated design not only achieves oxidation protection but also simultaneously solves the hidden dangers of pin bridging, comprehensively improving the quality of the tinning process.
