Description

Technical Field

[0001] The invention relates to the field of transformer soldering, and in particular to automatic transformer soldering equipment. Background Art

[0002] During the transformer production process, in order to facilitate good contact and firm fixation between the transformer lead wires and the terminal posts, the lead wires on the transformer are usually soldered before being welded to the terminal posts. After the soldering operation on the transformer lead wires, the welding quality of the lead wires in subsequent welding processes can be effectively enhanced, and the probability of desoldering, cold soldering and other conditions can be reduced.

[0003] When soldering the transformer lead wires, since there are a large number of lead wires on the transformer, in order to speed up the efficiency of soldering and tinning the lead wires and to reduce the labor intensity of the staff, the relevant technology mostly adopts the tinning process to solder and tinn the transformer lead wires. When operating the tinning equipment with a high degree of automation, most of them clamp and fix the transformer through automated clamping components, and drive the transformer to move back and forth between the conveyor belt and the tin pot. Through stroke control, the depth and duration of the transformer lead wires immersed in the rosin pot and the tin pot are adjusted, so that the melted tin liquid in the tin pot is evenly wrapped on the transformer lead wires, which is convenient for the subsequent welding operation of the transformer lead wires.

[0004] During the soldering process, as the working time increases, the amount of tin liquid will gradually decrease, causing the water level of the tin liquid to drop, resulting in different heights of the lead wires of the subsequent transformer soldering. In order to ensure the consistency of the soldering of each transformer lead wire, it is necessary to add tin liquid to the tin tank regularly and quantitatively.

[0005] The existing method generally uses a liquid level sensor to monitor the amount of tin liquid in real time and cooperates with control equipment, liquid delivery equipment, etc. for automatic filling. However, this method not only increases the cost of soldering equipment, but also the electronic equipment is used in a high-temperature and complex tin liquid environment, which is prone to malfunctions and causes untimely and inaccurate liquid replenishment, or even failure to automatically replenish the liquid, and has poor reliability.

DETAILED DESCRIPTION

[0040] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0041] The present invention provides a transformer automatic soldering device, such as Figure 1-7 As shown, including:

[0043] The traverse mechanism 7 is arranged on the top of both sides of the frame 1;

[0044] The lifting mechanism 8 is detachably mounted on the free end of the transverse movement mechanism 7, and a bracket 9 is provided at the free end thereof. Pneumatic clamps 10 are provided on both sides of the bottom of the bracket 9, and two clamping knives 11 that move relative to each other are connected to the bottom of the pneumatic clamp 10;

[0045] Among them, two spring seats 14 are arranged at the bottom of the inner tank 42, and the two spring seats 14 are fixedly mounted on the frame 1 through the base 13 to elastically support the inner tank 42. The spring seats 14 are used to lift the height of the inner tank 42 by increasing or decreasing the amount of tin liquid in the inner tank 42, so that the gradually decreasing tin liquid level always maintains the same height on the frame 1;

[0046] Specifically, the tin bath 4 adopts an inside-outside design, and the inner bath 42 is elastically placed in the outer bath 41 and elastically supported by the additional spring seat 14 and the base 13. As the soldering work progresses, the amount of tin liquid in the inner bath decreases, so that the overall inner bath 42 reduces the pressure value on the spring seat 14, and then the elastic force of the spring seat 14 pushes the inner bath 42 upward, achieving height adaptability and height adjustment of the inner bath 42, so that the gradually decreasing tin liquid level always maintains the same height on the frame, ensuring the consistency of the transformer soldering.

[0047] A liquid storage box 15 is provided at the bottom of the base 13, and a piston plate 153 is provided inside the liquid storage box 15. A connecting rod 16 is connected to the bottom surface of the inner groove 42, and the connecting rod 16 passes through the base 13, the liquid storage box 15 and is connected with the piston plate 153. A connecting pipe 152 is provided at the bottom of the liquid storage box 15, and the connecting pipe 152 is communicated with the inner groove 42. When soldering, the transverse movement mechanism 7 and the lifting mechanism 8 are used to drive the clamping knife 11 that clamps the product to move and press down the elastically installed inner groove 42, so that the connecting rod 16 moves downward to press down the piston plate 153 to transport the tin liquid inside the liquid storage box 15 to the inner groove 42 to maintain the amount of tin in the inner groove 42 and reset the tin liquid.

[0048] Specifically, a liquid storage box 15 is provided below the base 13, and can be connected to the bottom of the inner groove 42 by a connecting pipe 152. When the inner groove 42 moves upward due to the reduction of tin liquid, the connecting rod 16 is driven to extend. During soldering, the clamping knife 11 that moves up and down by the lifting mechanism 8 presses the inner groove 42 to reset it, so that the inner groove 42 moves downward, so that the piston plate 153 is pressed down by the connecting rod 16 to transport the tin liquid inside the liquid storage box 15 to the inner groove 42, realizing automatic tinning, so that the tin liquid always maintains the same liquid level height, greatly improving the consistency of the transformer lead wire soldering, improving the transformer soldering effect, and relying on the soldering equipment itself to achieve liquid replenishment and filling, which not only reduces the production cost of investment, but also greatly improves the reliability of the equipment, and ensures the timeliness and accuracy of liquid filling.

[0049] In this embodiment, if Figure 1-10As shown, the connecting rod 16 includes a fixed cylinder 161 and a telescopic rod 162, two symmetrical limit plates 163 are movably installed on both sides of the fixed cylinder 161, and each limit plate 163 is provided with a plurality of equally spaced oblique teeth 164, and knobs 165 are threadedly connected to both sides of the fixed cylinder 161, and the knobs 165 penetrate the fixed cylinder 161 and are rotatably connected to the limit plates 163, and a plurality of equally spaced grooves 166 are provided on both sides of the telescopic rod 162, and a movable tooth 167 is hingedly connected to the inside of each groove 166, and a circular hole 168 is provided on the inclined surface of the groove 166, and a spring 169 is provided inside the circular hole 168, and the two ends of the spring 169 are respectively connected to the inner wall of the circular hole 168 and the movable tooth 167.

[0050] Specifically, the groove 166 has a V-shaped structure, and the bottom inclined surface of the groove 166 is spaced a certain distance from the movable tooth 167. Under the action of the spring 169, the movable tooth 167 is moved away from the inclined surface of the groove 166, so as to provide the movable tooth 167 with space to move up and down, so that the movable tooth 167 can move freely in the groove 166, and the top surface of the groove 166 contacts the top surface of the movable tooth 167 to limit the upward direction of the movable tooth 167, so that during operation, the telescopic rod 16 can only move upward following the inner groove 42, and cannot be retracted into the fixed cylinder 161, thereby realizing continuous downward pressure on the piston plate 153 and ensuring continuous liquid addition.

[0051] In this embodiment, if Figure 1 , Figure 7 As shown, a material tray 5 is provided at the front end of the frame 1 for temporarily storing transformer products, and a detachable material swinging mold 6 is provided at the rear end of the material tray 5. The material swinging mold 6 is in a straight line shape and is used to spread the transformer products in a straight line for easy grasping by the clamp.

[0052] Specifically, the transformers can be stacked in the material tray 5 to facilitate material retrieval, and the plurality of transformers can be arranged in a row by using the swinging material mold 6, so that the clamping knife can clamp the plurality of transformers at one time for welding.

[0053] In this embodiment, if Figure 1 , Figure 7 As shown, a conveyor belt 12 is installed on the frame 1 between the cleaning tank 2 and the material tray 5 for conveying the soldered products to the next process.

[0054] Specifically, after the welding of the transformer is completed, the transformer is placed on the conveyor belt 12 by using the transverse movement mechanism 7 and the lifting mechanism 8, and is conveyed to the next production and processing procedure.

[0055] In this embodiment, if Figure 2 , Figure 4 As shown, a liquid inlet 151 is provided on one side of the top of the liquid storage box 15 , and observation windows are provided on the front and back sides of the liquid storage box 15 for observing the amount of tin liquid inside the liquid storage box 15 .

[0056] Specifically, the liquid inlet 151 is used to replenish the liquid storage box 15, and the observation window is convenient for observing the amount of tin liquid inside the liquid storage box 15, and then deciding whether refilling is needed.

[0057] In this embodiment, if Fig.11 As shown, the transverse movement mechanism 7 includes a shell 71, a pulley 72, a belt 73, a first motor 74 and a moving block 75, wherein the shell 71 is fixedly mounted on the frame 1, and two pulleys 72 are rotatably mounted at both ends of each shell 71, and the two pulleys 72 are connected to a belt 73, and a moving block 75 is detachably mounted on the belt 73, and the two moving blocks 75 are symmetrical on the left and right.

[0058] Specifically, the first motor 74 drives one of the pulleys 72 to rotate, and cooperates with the other pulley 72 to drive the belt 73 to operate, thereby driving the moving block 75 forward and backward, and further realizing the forward and backward driving of the lifting mechanism 8.

[0059] In this embodiment, if Fig.12 As shown, the lifting mechanism 8 includes a cross beam 81, a top plate 82, a screw rod 83, a guide rod 84, a lifting plate 85, a threaded sleeve 86, a guide sleeve 87, a second motor 88 and a coupling 89, wherein the cross beam 81 is fixedly installed between the two moving blocks 75, the screw rod 83 is rotatably installed in the middle of the top surface of the cross beam 81, the guide rod 84 is fixedly connected to both sides of the top surface of the cross beam 81, the middle of the top plate 82 is rotatably connected to the screw rod 83, the two sides of the top plate 82 are fixedly connected to the guide rod 84, the middle of the lifting plate 85 is plugged with a threaded sleeve 86, the two sides of the lifting plate 85 are plugged with guide sleeves 87, the threaded sleeve 86 is threadedly sleeved with the screw rod 83, the guide sleeve 87 is slidably sleeved with the guide rod 84, the second motor 88 is fixedly installed on the top plate 82 and its output shaft is connected with a coupling 89, and one end of the coupling 89 is connected to the screw rod 83.

[0060] Specifically, the second motor 88 drives the screw 83 to operate through the connected coupling 89. Since the threaded sleeve 86 is threadedly connected to the screw 83 and under the sliding limit of the guide sleeve 87 and the guide rod 84, the lifting plate 85 moves up and down, thereby driving the pneumatic clamp 10, the clamping knife 11 and the transformer on the bracket 9 to rise and fall.

[0061] In this embodiment, if Fig.12 As shown, the bracket 9 is in an L-shaped structure, one end of which is used to connect with the lifting plate 85, and the other end is used to install the pneumatic clamp 10.

[0062] In this embodiment, if Figure 3 As shown, a plurality of rollers 44 are arranged around the inner wall of the outer groove 41 , and pressure blocks 43 are arranged on the top surfaces of both sides of the inner groove 42 .

[0063] Specifically, the plurality of rollers 44 reduce the friction between the inner groove and the outer groove, so that the inner groove can be raised and lowered more accurately due to the change in the amount of tin liquid. The pressing block 43 abuts against the clamping knife 11 to prevent the clamping knife 11 from causing unnecessary damage to the inner groove 42 .

[0064] In this embodiment, if Figure 2 As shown, the liquid storage box 15 is designed to correspond to the inner tank 42 in the upper and lower parts, and the length and width of the liquid storage box 15 are the same as those of the inner tank 42, and the depth is at least twice that of the inner tank 42.

[0065] Specifically, in actual use, the volume of 15 is designed according to the usage of the tin liquid, and because the length and width of the liquid storage box 15 are the same as the inner groove 42, the rising height caused by the reduction of the tin liquid in the inner groove 42 is the same as the feeding movement length of the reset pressing piston plate 153, so that the reduction of the tin liquid is the same as the addition of liquid, thereby improving the accuracy of the control of the addition of tin liquid.

[0066] The working principle of the present invention is as follows: first, the transformers are stacked in the material tray 5, and then the plurality of transformers are arranged in a row using the swinging mold 6, and then the equipment is started, and the transverse movement mechanism 7 and the lifting mechanism 8 are used to transport the transformers, and the transformers enter the cleaning tank 2, the drying tank 3, and the tin tank 4 one by one, and the transformers that have completed soldering are transported to the conveyor belt 12 for conveying to the next process. As the soldering work proceeds, the amount of tin liquid in the inner tank 42 decreases, so that the overall inner tank 42 reduces the pressure value on the spring seat 14, and then the elastic force of the spring seat 14 pushes the inner tank 42 upward. When the lifting height is greater than the spacing of the bevel teeth 164, the lifting mechanism 8 drives the clamping knife 11 to press the inner tank 42 down to reset it, so that the inner tank 42 moves downward, thereby pressing the piston plate 153 down through the connecting rod 16 to transport the tin liquid inside the liquid storage box 15 to the inner tank 42, thereby realizing automatic tinning.
