Description

Technical Field

[0001] The utility model relates to the technical field of transformer production equipment, in particular to a welding sheet assembly device. Background Art

[0002] During the production process of transformers, it is common to place welding lugs when welding the transformer coil terminals. The main function of welding lugs is to help the welding process go more smoothly and improve the welding quality. However, the size and placement of welding lugs will have a significant impact on the welding quality.

[0003] First of all, the size of the soldering lug needs to be moderate. If the soldering lug is too large, too much flux may be brought into the solder joint during welding, which may cause embrittlement and corrosion of the solder joint. If the soldering lug is too small, it may not provide enough flux, affecting the fusion effect and welding quality during welding. Therefore, it is very important to choose the appropriate length of the soldering lug.

[0004] In addition, the placement of the solder tab is also critical. The solder tab should be placed in the appropriate position of the solder joint to ensure that the flux can evenly and effectively cover the soldering surface. If the solder tab is not placed properly, some areas of the solder joint may not be fully exposed to the flux, thus affecting the soldering quality.

[0005] In short, the size and placement of the welding piece are important factors affecting the welding quality. If the above welding piece assembly operations are all performed manually, the welding quality may fluctuate due to differences in the operator's technical level and experience. This may lead to unstable quality of the welded joint, thereby affecting the performance and reliability of the transformer. Moreover, during the manual welding process, the operator needs to directly contact the high-temperature welding tools and molten metal, which poses certain safety hazards. Therefore, it is necessary to propose a welding piece assembly device to realize the mechanical automation assembly production of the above welding piece assembly operation. Utility Model Content

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] like Figure 1-9 As shown, a welding piece assembly device comprises a first support frame 1, a second support frame 2 and a first fixing plate 3;

[0056] The first support frame 1 and the second support frame 2 are arranged in parallel, the first fixing plate 3 is arranged in front of the first support frame 1 and the second support frame 2, and a fixing seat 4 is installed on the upper plate surface of the first fixing plate 3, and the fixing seat 4 is used to fix the coil terminal 100 of the transformer;

[0057] The first support frame 1 is provided with a first movable structure 5, and the first movable structure 5 is movably connected with a welding piece assembly body 6;

[0058] The welding piece assembly machine body 6 includes a welding machine 61 and a nozzle machine 62, and the nozzle machine 62 is symmetrically arranged on both sides of the welding machine 61;

[0059] The second support frame 2 is provided with a solder piece cutting structure 7, and the solder piece cutting structure 7 is used to cut solder pieces 200 of a preset size.

[0060] like Figure 1-2 As shown, first, after the welding piece 200 of a preset size is cut by the welding piece cutting structure 7, the welding piece assembly body 6 is then moved to a designated position by the first moving structure 5, and the nozzle machine 62 is started to suck the welding piece 200. Since the coil terminal 100 of the transformer has two points to be welded, two nozzle machines 62 are provided to suck one welding piece 200 respectively. After the successful suction, according to the placement requirements of the welding piece 200, the first moving structure 5 is started to transfer one welding piece 200 to one point to be welded of the coil terminal 100 of the transformer fixed by the fixing seat 4, and then the welding machine 61 is used for welding and fixing, and then the welding piece 200 of the other point to be welded of the coil terminal 100 of the transformer is assembled.

[0061] In summary, when the welding piece 200 of the transformer is assembled, the welding piece cutting structure 7 can adjust the appropriate length and quantity of the welding piece 200, and the nozzle machine 62 on the first movable structure 5 can place it at a suitable position on the coil terminal 100 of the transformer, so as to facilitate the welding joint of the welding machine 61 to perform accurate welding to ensure welding quality and safety. At the same time, the welding process parameters and operation methods of the welding piece assembly device can be adjusted according to specific circumstances to obtain the best welding effect.

[0062] Further explanation, it also includes a second fixed plate 8, which is arranged in front of the fixed seat 4, and a second movable structure 9 is installed on the upper plate surface of the second fixed plate 8, and a welding piece straightening structure 10 is movably connected to the second movable structure 9.

[0063] Before the welding machine 61 welds the welding piece 200, the utility model adds a welding piece straightening structure 10 to replace manual straightening, thereby realizing the pre-fixing function of the coil terminal 100 of the transformer and playing an auxiliary straightening effect, eliminating safety hazards while ensuring that the welding piece 200 can evenly and effectively cover the welding surface of the coil terminal 100 of the transformer, fundamentally solving the quality hazards caused by improper placement of the welding piece 200.

[0064] To further illustrate, the welding sheet cutting structure 7 includes an unwinding component 71, a straightening component 72 and a cutting component 73;

[0065] The unwinding assembly 71 is installed on the side of the second support frame 2 away from the first support frame 1, and the unwinding assembly 71 is used to place the welding ribbon roll 300;

[0066] The straightening assembly 72 is disposed close to the unwinding assembly 71, and the straightening assembly 72 is used to pull the fixed-length welding strip 400;

[0067] The cutting assembly 73 is disposed close to the straightening assembly 72 , and the cutting assembly 73 is used to cut the fixed-length welding strip 400 .

[0068] like Figure 3 As shown, the utility model can fix the soldering ribbon roll 300 during the unwinding process by setting the unwinding component 71, and naturally unwind the soldering ribbon 400 of the soldering ribbon roll 300 to the straightening component 72. When the soldering ribbon 400 is led out of the soldering ribbon roll 300 through the straightening component 72, it can ensure that the soldering ribbon 400 is straight before entering the cutting component 73, and the fixed-length soldering ribbon 400 is pulled to facilitate accurate cutting by the cutting component 73.

[0069] To further explain, the unwinding assembly 71 includes an unwinding roller 711 and a plurality of tensioning rollers 712 , and one end of the unwinding roller 711 and one end of the plurality of tensioning rollers 712 are rotatably mounted on the side of the second support frame 2 away from the first support frame 1 .

[0070] like Figure 4 As shown, the unwinding roller 711 in the present invention is used to place the welding tape roll 300, and the tensioning rollers 712 are used to adjust the tension of the welding tape 400 led out of the welding tape roll 300. Specifically, when the welding tape 400 led out of the welding tape roll 300 is sequentially wound around the tensioning rollers 712, the tensioning rollers 712 can pre-tension the welding tape 400 to ensure that the welding tape 400 is always in a straightened state.

[0071] To further illustrate, the straightening assembly 72 includes a U-shaped seat 721, an adjustment seat 722, a feeding roller 723, a straightening roller 724 and a feeding motor 725;

[0072] The U-shaped seat 721, the adjustment seat 722, the feeding roller 723 and the straightening roller 724 are all installed on the side of the second support frame 2 away from the first support frame 1, and the feeding motor 725 is installed on the side of the second support frame 2 close to the first support frame 1, and the driving shaft of the feeding motor 725 passes through the second support frame 2, and the driving shaft of the feeding motor 725 is fixedly installed with the feeding roller 723;

[0073] Both ends of the U-shaped seat 721 are fixedly mounted with guide mounting blocks 726. The U-shaped seat 721 and the guide mounting blocks 726 have mounting recesses on their opposite surfaces. Guide plates 727 are embedded in the mounting recesses. A guide channel 728 is formed between the two guide plates 727 facing each other vertically, and a straightening space 729 is formed between the two guide plates 727 facing each other horizontally.

[0074] The adjustment seat 722 is detachably installed at the opening of the U-shaped seat 721, the feeding roller 723 is located in the adjustment seat 722, the straightening roller 724 is rotatably installed on the adjustment seat 722, the straightening roller 724 and the feeding roller 723 are arranged opposite to each other up and down, part of the roller surface of the straightening roller 724 and part of the roller surface of the feeding roller 723 are located in the straightening space 729, and the guide plate 727 is close to the straightening space 729 to form an air avoidance arc surface, and the air avoidance arc surface is respectively adapted to the roller surfaces of the straightening roller 724 and the feeding roller 723.

[0075] like Figure 5-7As shown, specifically, the welding ribbon 400 led out of the unwinding assembly 71 passes through the straightening space 729 between one of the upper and lower guide plates 727 disposed near the unwinding assembly 71, then passes through the straightening roller 724 disposed upper and lower and the feeding roller 723 disposed upper and lower, and finally passes through the straightening space 729 between the other upper and lower guide plates 727 disposed upper and lower. Then, the feeding motor 725 is started to drive the feeding roller 723 to rotate, thereby driving the welding ribbon 400 to be transported horizontally. During the rotation process, part of the roller surface of the upper and lower straightening roller 724 and part of the roller surface of the feeding roller 723 press the upper and lower surfaces of the welding ribbon 400 to straighten, thereby realizing the automatic straightening process of the welding ribbon 400, and the single rotation threshold can be controlled and adjusted in advance by the feeding motor 725, that is, the fixed-length welding ribbon 400 is pulled, thereby avoiding the large error problem caused by manual adjustment, saving labor and improving product quality.

[0076] More applicable is that the straightening space 729 between the straightening roller 724 in the adjustment seat 722 and the feeding roller 723 in the U-shaped seat 721 is adjustable, and the guide channel 728 between the guide plate 727 in the U-shaped seat 721 and the guide plate 727 in the guide mounting block 726 is adjustable, so that the feeding assembly 71 can adapt to welding strips of different thicknesses. Moreover, the guide channel 728 formed between the upper and lower guide plates 727 can guide and transmit the welding strip 400 to avoid severe deformation of the welding strip 400, thereby reducing the probability of the welding strip 400 breaking.

[0077] To further illustrate, the cutting assembly 73 includes a discharge plate 731;

[0078] The side of the discharge plate 731 is fitted with the side of the U-shaped seat 721, and the discharge plate 731 is arranged away from the unwinding assembly 71. A discharge recess is provided on the top of the discharge plate 731, and the discharge recess is arranged corresponding to the outlet of the guide channel 728;

[0079] Cutting and mounting blocks 732 are protruding upwards on both sides of the discharge recess, and cutting blades 733 are detachably mounted on the two cutting and mounting blocks 732;

[0080] Two limit blocks 734 are installed on the side of the discharge plate 731 away from the U-shaped seat 721, a cutting sliding block 735 is slidably installed between the two limit blocks 734, an adsorption block 736 is installed above the cutting sliding block 735, the upper surface of the adsorption block 736 is flush with the discharge recess, and a cutting driver 737 is installed below the cutting sliding block 735, the driving shaft of the cutting driver 737 is fixedly connected to the cutting sliding block 735, and the cutting driver 737 is used to drive the cutting sliding block 735 to slide between the two limit blocks 734;

[0081] The adsorption block 736 is provided with a plurality of suction ports, a suction cylinder 738 is installed below the adsorption block 736, a driving end of the suction cylinder 738 is connected to the adsorption block 736, fixed blocks 739 are installed at both ends of the adsorption block 736, and a pressing plate 730 is detachably installed above the two fixed blocks 739.

[0082] like Figure 5-7 As shown, specifically, the welding strip 400 led out of the straightening assembly 72 is led out from the discharge notch of the discharge plate 731 and placed on the upper surface of the adsorption block 736. After the feeding motor 725 rotates once, the cutting driver 737 is started to make the cutting sliding block 735 slide along the plate surface of the discharge plate 731 between the two limit blocks 734. When the cutting sliding block 735 slides over the cutting blade 733 above the discharge plate 731, the cutting blade 733 cuts off the fixed-length welding strip 400, that is, the welding piece 200. In addition, in order to ensure the cutting size accuracy, the pressing plate 730 above the fixed blocks 739 at both ends of the adsorption block 736 will press the fixed-length welding strip 400.

[0083] More applicable is that, since the weight of the cut welding piece 200 is relatively light, in order to prevent the welding piece 200 from moving and causing the suction nozzle machine 62 to suck inaccurately, an air suction cylinder 738 is further provided, so that the several air suction holes on the suction plate can suck the welding piece 200 to prevent it from moving. Moreover, the suction force of the air suction cylinder 738 is smaller than the suction force of the suction nozzle machine 62, ensuring that the suction nozzle machine 62 can suck the welding piece 200 on the suction plate.

[0084] For further explanation, the solder sheet cutting structure 7 further includes a detection sensor 74 , and the detection sensor 74 is installed on a side of the second support frame 2 away from the first support frame 1 .

[0085] It should be noted that the detection end of the detection sensor 74 is directed toward the soldering ribbon 400 led out of the soldering ribbon roll 300. Figure 5 As shown, it is necessary to ensure that the distance between the detection sensor 74 and the soldering ribbon 400 is within the sensing range of the detection sensor 74. The detection sensor 74 is used to detect whether the soldering ribbon roll 300 is used up, so as to conveniently remind the user to replace the used soldering ribbon roll 300.

[0086] To further illustrate, the welding piece straightening structure 10 includes a driver 101 and two straightening members 102;

[0087] The two straightening members 102 are L-shaped members, one end of each of the straightening members 102 is fixedly mounted on the driving shaft of the driver 101, and a connecting rod 103 is movably connected between the other ends of the two straightening members 102. The driver 101 is used to adjust the two straightening members 102 to move away from or closer to each other along the rod direction of the connecting rod 103.

[0088] like Figure 8-9As shown, the utility model uses a driver 101 to adjust two straightening pieces 102 to adapt to the assembly of welding pieces of coil terminals of transformers of different sizes. Furthermore, the connecting rod 103 is inserted into the two straightening pieces 102 to connect and fix the two straightening pieces 102, and the two straightening pieces 102 can be assembled together to straighten the two welding points of the coil terminal of the transformer, straightening the coil terminal 100 of the transformer while preventing unilateral shaking.
