Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of welding equipment, and in particular to a welding sheet feeding module and electric welding equipment. Background Art

[0002] Welding technology is widely used in the manufacturing industry. However, due to some external reasons such as machine precision or inertia, the solder pushing accuracy during the welding process is often difficult to accurately control. Insufficient solder pushing will cause cold solder joints and affect product quality. Excessive solder pushing may cause material waste and increase costs.

[0003] Therefore, there is an urgent need for a mechanism that can accurately push the solder to solve the above problems. Utility Model Content

[0004] In view of the above problems, the embodiments of the present application provide a welding sheet feeding module and an electric welding device, which solve the problem that the welding sheet feeding cannot be accurately controlled during the material welding process.

[0005] According to one aspect of an embodiment of the present application, a solder sheet feeding module is provided, which includes a solder sheet feeding mechanism and a solder sheet discharging mechanism. The solder sheet feeding mechanism is used to transfer the solder sheet to the solder sheet discharging mechanism; the solder sheet discharging mechanism includes a discharging table and a detection component. The discharging table is provided with a discharging trough, and the discharging trough runs through the discharging table. One end of the discharging trough forms a solder sheet inlet, and the other end forms a solder sheet outlet. The solder sheet can pass through the solder sheet inlet and pass through the solder sheet outlet to weld parts; the detection component is arranged on one side of the discharging trough, and the detection component detects two positions along the length direction of the discharging trough, and determines the position of the end of the solder sheet according to the solder sheet conditions detected at the two positions.

[0006] By adopting the above scheme, the welding piece feeding mechanism is used to transfer the welding piece to the welding piece discharging mechanism, so that the welding piece enters the discharging slot from the welding piece inlet, passes through the welding piece outlet, and enters between the parts to be welded outside the welding piece outlet, and is used to weld two parts to be welded. By detecting the two positions of the discharging slot by the detection component, it can be determined whether there are welding pieces at these two positions, thereby further inferring the position of the end of the welding piece relative to the two detected positions. According to the position of the end of the welding piece, it is convenient to relatively accurately control the length of the welding piece sent out from the welding piece outlet, reducing the cost waste or welding quality problems caused by the different lengths of the welding pieces, so as to achieve the purpose of saving costs and ensuring the stability of the quality of welding products.

[0007] In some embodiments, a first detection hole and a second detection hole are further provided on the discharge table. The first detection hole and the second detection hole are arranged in sequence along the length direction of the discharge trough and are both connected to the discharge trough. The first detection hole is close to the welding piece outlet and the second detection hole is close to the welding piece inlet. The detection component includes a corresponding optical fiber, which determines the position of the end of the welding piece by detecting the optical signals of the first detection hole and the second detection hole.

[0008] By adopting the above scheme, the first detection hole can detect the position of the welding piece, and the second detection hole is connected to the first detection hole to assist in judging whether the detection of the first detection hole is effective. The opposite-shooting optical fiber can obtain the position of the end of the welding piece relative to the part directly facing the first detection hole and the second detection hole by detecting the optical signals of the first detection hole and the second detection hole. In addition, the opposite-shooting optical fiber has low cost and high detection accuracy, saving equipment cost.

[0009] In some embodiments, the solder sheet feeding module further includes a solder sheet locking mechanism, and the solder sheet locking mechanism includes a solder sheet pressing platform and a solder sheet pressing cylinder.

[0010] A welding piece groove is provided on the welding piece pressing platform, and the welding piece groove is located in the extension direction of the discharge chute along the side of the welding piece inlet; the cylinder body of the welding piece pressing cylinder is fixed on the welding piece pressing platform, the piston rod of the welding piece pressing cylinder is perpendicular to the welding piece groove, and the end of the piston rod of the welding piece pressing cylinder is facing the welding piece groove, so as to press the welding piece after determining the position of the end of the welding piece.

[0011] The soldering slot is located in the extending direction of the discharge slot along the soldering slot inlet, so that after the soldering slot passes through, the soldering slot can directly enter the soldering slot inlet and pass through the discharge slot. After determining the position of the end of the soldering slot, the soldering slot pressing cylinder presses the soldering slot, so that the position of the soldering slot can only change with the soldering slot locking mechanism, thereby preventing the position of the soldering slot end from changing during the subsequent operation of the soldering slot feeding module, affecting the reliability of the judgment of the position of the soldering slot end.

[0012] In some embodiments, the solder sheet feeding mechanism includes: a solder sheet feeding table and a solder sheet feeding cylinder.

[0013] The welding piece pressing platform is slidably arranged on the welding piece feeding platform along the length direction of the welding piece groove; the cylinder body of the welding piece feeding cylinder is fixed on the welding piece feeding platform, and the piston rod of the welding piece feeding cylinder is against the welding piece pressing platform, so that after the welding piece pressing cylinder presses the welding piece, the welding piece pressing platform is pushed, so that the welding piece pressing platform drives the welding piece to move toward the direction close to the discharge platform.

[0014] By adopting the above scheme, the welding piece clamping platform is slidably arranged on the welding piece feeding platform along the length direction of the welding piece groove, so that the welding piece clamping platform can slide relative to the welding piece feeding platform. The welding piece feeding cylinder can push the welding piece clamping platform, so that the welding piece clamping platform drives the welding piece to move in the direction close to the discharge platform, so that the end of the welding piece can be extended from the welding piece outlet for welding the parts to be welded. In the above process, since the position of the end of the welding piece has been determined, the pushing stroke of the welding piece feeding cylinder can be adjusted according to the position of the end of the welding piece, or, after adjusting the end of the welding piece to a certain position according to the position of the end of the welding piece, the welding piece feeding cylinder is controlled to push out a certain stroke, so as to achieve the effect of accurately controlling the length of the welding piece sent out from the welding piece outlet.

[0015] In some embodiments, the welding sheet feeding module also includes a workbench, and the welding sheet feeding table is slidably set on the workbench along the length direction of the welding sheet groove; the welding sheet discharging mechanism is arranged on the welding sheet feeding table; the welding sheet feeding mechanism also includes a platform pushing cylinder, and the cylinder body of the platform pushing cylinder is fixed on the workbench, and the piston rod of the platform pushing cylinder is connected to the welding sheet feeding table, which is used to push the welding sheet feeding table to move, so that the welding sheet feeding table drives the welding sheet discharging mechanism, the welding sheet locking mechanism and the welding sheet to approach the parts to be welded.

[0016] By adopting the above scheme, when the piston rod of the platform push cylinder is pushed out, it can drive the welding piece feeding platform to move. Since the welding piece locking mechanism and the welding piece discharging mechanism are both arranged on the welding piece feeding platform, the movement of the welding piece feeding platform can drive the welding piece locking mechanism and the welding piece discharging mechanism to move together. When the welding piece is clamped by the welding piece locking mechanism, the welding piece will also move with the welding piece feeding platform in the direction close to the part to be welded, and in this process, the relative positions of the welding piece, the welding piece locking mechanism and the welding piece discharging structure remain unchanged. Through this arrangement, before the end of the welding piece passes through the welding piece outlet, the platform pushing mechanism can drive the welding piece, the welding piece locking mechanism and the welding piece discharging mechanism to approach the part to be welded together. After that, the welding piece only needs to pass through a short distance from the welding piece outlet to enter between the parts to be welded, thereby reducing the uncertainty of the position of the end of the welding piece caused by the welding piece passing through the welding piece outlet too long and bending, and reducing the welding error rate.

[0017] In some embodiments, the welding piece feeding module also includes a welding piece shaping mechanism, which includes: a shaping table and a plurality of guide wheels, the shaping table is arranged on the side where the welding piece entrance is located; the plurality of guide wheels are rotatably connected to the shaping table, the plurality of guide wheels are arranged in two rows, and the welding piece passes between the two rows of guide wheels to straighten the welding piece.

[0018] By adopting the above scheme, the incoming soldering sheet is often wound on the reel, and after being wound off the reel, it is often bent, and the bending direction is random, which often leads to the problem that the soldering sheet is difficult to be transferred to the set position. By setting up a soldering sheet shaping mechanism, the soldering sheet is squeezed by two rows of guide wheels before entering the soldering sheet entrance. The guide wheels can not only play the role of transferring the soldering sheet in a specific direction, but also reduce the bending degree of the soldering sheet, so that the soldering sheet can be transferred to a specific position, which is conducive to the accurate transfer of the soldering sheet.

[0019] In some embodiments, the welding piece shaping mechanism also includes: an adjusting block, an adjusting screw and an elastic member; the adjusting block is slidably mounted on the shaping table, wherein a row of guide wheels is mounted on the adjusting block; the adjusting screw is connected to the shaping table; one end of the elastic member abuts against the adjusting block, and the other end abuts against the adjusting screw.

[0020] By adopting the above scheme, by adjusting the distance between the adjusting screw and the adjusting block, the degree of compression of the elastic member can be changed, thereby changing the force applied by the elastic member to the adjusting block, and then changing the distance between the two rows of guide wheels or changing the pressure of the two rows of guide wheels on the welding piece, so that the guide wheels are suitable for shaping welding pieces of various thicknesses or hardnesses.

[0021] In some embodiments, a blowing channel is further provided on the discharge platform, one end of the blowing channel is connected to the discharge trough, and the other end is connected to the outside of the side wall of the discharge platform.

[0022] By adopting the above solution, air can be blown from one end of the blowing channel connected to the outside of the side wall of the discharge platform to clean the welding slag on the welding piece in the discharge trough, thereby ensuring the welding quality of the welding piece to the part.

[0023] According to another aspect of an embodiment of the present application, a welding device is provided, comprising the welding sheet feeding module in any of the above embodiments.

[0024] To summarize, the soldering sheet delivery module of the embodiment of the present application is equipped with a detection component, which can detect the two positions of the material trough and determine whether there are soldering sheets at these two positions, thereby further inferring the position of the end of the soldering sheet relative to the two detected positions. According to the position of the end of the soldering sheet, it is convenient to relatively accurately control the length of the soldering sheet delivered from the soldering sheet outlet, thereby reducing the cost waste or welding quality problems caused by the different lengths of soldering sheets, thereby achieving the purpose of saving costs and ensuring the stability of the quality of welding products.

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0038] The term "and / or" in this article is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0039] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the welding sheet feeding module or the welding equipment of the present application. For example, in the description of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0040] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0043] In the field of electrical equipment, welding technology is often needed. However, the welding pieces sent out by the existing welding piece feeding module are sometimes long and sometimes short. When the length of the welding piece sent out is greater than the required length, it will cause waste of welding pieces. When the length of the welding piece sent out is less than the required length, it will cause loose welding between parts, resulting in problems such as cold welding, thereby reducing the welding qualification rate of the product.

[0044] In view of the above problems, an embodiment of the present application provides a soldering sheet feeding module.

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, the solder sheet feeding module includes a solder sheet feeding mechanism 100 and a solder sheet discharging mechanism 200 . The solder sheet feeding mechanism 100 is used to transfer the solder sheet 700 to the solder sheet discharging mechanism 200 .

[0046] The solder piece discharging mechanism 200 includes a discharging platform 210 and a detection component 220. The discharging platform 210 is provided with a discharging slot 211, which is arranged through the discharging platform 210. One end of the discharging slot 211 forms a solder piece inlet 212, and the other end forms a solder piece outlet 213. The solder piece 700 can pass through the solder piece inlet 212 and pass through the solder piece outlet 213 to weld parts. The detection component 220 is arranged on one side of the discharging slot 211. The detection component 220 detects two positions along the length direction of the discharging slot 211, and determines the position of the end of the solder piece 700 according to the conditions of the solder piece 700 detected at the two positions.

[0047] The detection component 220 may include any one of laser detection, infrared detection, and optical fiber detection.

[0048] Exemplarily, in some embodiments, a first detection hole 214 and a second detection hole 215 are further provided on the discharge platform 210. The first detection hole 214 and the second detection hole 215 are arranged in sequence along the length direction of the discharge trough 211 and are both connected to the discharge trough 211. The first detection hole 214 is close to the welding piece outlet 213, and the second detection hole 215 is close to the welding piece inlet 212.

[0049] The detection assembly 220 includes a counter-radiation optical fiber, which detects optical signals from the first detection hole 214 and the second detection hole 215 to determine the position of the end of the welding piece 700 .

[0050] Among them, the opposing optical fiber includes an emitting electrode and a receiving electrode, and the emitting electrode emits light at both the first detection hole 214 and the second detection hole 215; a signal receiving slot 217 is arranged on the side of the discharge slot 211 away from the first detection hole 214 and the second detection hole 215, and the receiving electrode of the opposing optical fiber is located in the signal receiving slot 217. By determining whether the receiving electrode can detect optical signals from the first detection hole 214 and the second detection hole 215, the position of the end of the welding piece 700 can be determined.

[0051] Exemplarily, the first detection hole 214 is connected to the second detection hole 215, and the emitter is located in the first detection hole 214, but the light of the emitter can also enter the second detection hole 215. The receiving electrode can determine the position of the soldering piece 700 by detecting whether there is an optical signal in the first detection hole 214, and the second detection hole 215 is used to assist in determining whether the detection of the first detection hole 214 is effective. The opposite optical fiber detects the optical signals of the first detection hole 214 and the second detection hole 215 to determine the position of the end of the soldering piece 700.

[0052] The specific principle and method of the incident optical fiber to determine the position of the end of the welding piece 700 by detecting the optical signals of the first detection hole 214 and the second detection hole 215 may be:

[0053] When signals are detected in both the first detection hole 214 and the second detection hole 215 , it means that there is no soldering piece 700 opposite to the first detection hole 214 and the second detection hole 215 , and the end of the soldering piece 700 is located on the side of the second detection hole 215 close to the soldering piece entrance 212 .

[0054] When no signal is detected in the first detection hole 214 and the second detection hole 215 , it means that there are welding pieces 700 opposite to the first detection hole 214 and the second detection hole 215 , and the end of the welding piece 700 is located on the side of the first detection hole 214 close to the welding piece outlet 213 .

[0055] When no signal is detected in the second detection hole 215 and a signal is detected in the first detection hole 214, it means that there is a welding piece 700 directly opposite the second detection hole 215 and there is no welding piece 700 directly opposite the first detection hole 214, then the end of the welding piece 700 is located between the first detection hole 214 and the second detection hole 215.

[0056] In some embodiments, when the end of the welding piece 700 is located on the side of the second inspection hole 215 close to the welding piece inlet 212, since the end of the welding piece 700 is far away from the welding piece outlet 213, the problem of poor welding of parts due to too little welding piece 700 being fed out can be prevented by increasing the length of the welding piece 700 fed out by the welding piece feeding mechanism 100.

[0057] When the end of the welding piece 700 is located on the side of the first inspection hole 214 close to the welding piece outlet 213, since the end of the welding piece 700 is closer to the welding piece outlet 213, the problem of excessive welding piece 700 being fed out and causing material waste can be prevented by reducing the length of the welding piece 700 fed out by the welding piece feeding mechanism 100.

[0058] When the end of the welding piece 700 is located between the first inspection hole 214 and the second inspection hole 215, the end of the welding piece 700 is moderately away from the welding piece outlet 213, and the length of the welding piece 700 sent out by the welding piece feeding mechanism 100 can be adjusted to a moderate length to prevent the problem of too much or too little welding piece 700 being sent out.

[0059] Since the end of the soldering piece 700 is located on the side of the second detection hole 215 close to the soldering piece inlet 212 and the end of the soldering piece 700 is located on the side of the first detection hole 214 close to the soldering piece outlet 213, the range of the position of the end of the soldering piece 700 is large, and it is difficult to have a smaller range to determine the position of the end of the soldering piece 700, while the distance between the first detection hole 214 and the second detection hole 215 is determined, and the position range can be narrowed by narrowing the distance between the first detection hole 214 and the second detection hole 215. Therefore, in some embodiments, the distance between the first detection hole 214 and the second detection hole 215 can be defined as the initial position.

[0060] When it is detected that the end of the welding piece 700 is not in the initial position, the position of the end of the welding piece 700 can be adjusted so that the end of the welding piece 700 reaches the initial position, and then the welding piece feeding mechanism 100 is controlled to send out the welding piece 700. In this way, the length of the welding piece 700 sent out by the welding piece feeding mechanism 100 each time is basically the same, which reduces the cost waste or welding quality problems caused by the different lengths of the welding pieces 700, thereby achieving the purpose of saving costs and ensuring the stability of the quality of welding products.

[0061] like Figure 3 As shown, in some embodiments, a blowing channel 216 is further provided on the discharge platform 210 , one end of the blowing channel 216 is connected to the discharge trough 211 , and the other end is connected to the outside of the side wall of the discharge platform 210 .

[0062] The blowing channel 216 may be a hole and / or a slot. When the blowing channel 216 includes a slot, the slot opening is closed so that the air flow of the blowing channel 216 can only flow from one end of the blowing channel 216 to the other end.

[0063] By setting up the blowing channel 216, air can be blown from one end of the blowing channel 216 close to the outside of the side wall of the discharge platform 210 with an air gun or a solenoid valve. The airflow reaches the discharge trough 211 along the blowing channel 216, and can blow away impurities such as welding slag in the discharge trough 211 and on the welding piece 700 located in the discharge trough 211, thereby preventing the welding slag from reaching between the parts to be welded along the welding piece 700 and affecting the welding quality of the parts to be welded.

[0064] By adopting the above solution, air can be blown from the blowing channel 216 connected to one end of the side wall outside the discharge platform 210 to clean the welding slag on the welding piece 700 located in the discharge trough 211, thereby ensuring the welding quality of the welding piece 700 to the part.

[0065] like Figure 1 and Figure 4 As shown, in some embodiments, the solder sheet feeding module further includes a solder sheet locking mechanism 300 , and the solder sheet locking mechanism 300 includes a solder sheet pressing platform 310 and a solder sheet pressing cylinder 320 .

[0066] A welding piece pressing platform 310 is provided with a welding piece groove 311, and the welding piece groove 311 is located in the extension direction of the discharge slot 211 along one side of the welding piece inlet 212; the cylinder body of the welding piece pressing cylinder 320 is fixed on the welding piece pressing platform 310, the piston rod of the welding piece pressing cylinder 320 is perpendicular to the welding piece groove 311, and the end of the piston rod of the welding piece pressing cylinder 320 is opposite to the welding piece groove 311, so as to press the welding piece 700 after determining the position of the end of the welding piece 700.

[0067] The solder piece slot 311 is located in the extending direction of the discharge slot 211 along one side of the solder piece inlet 212 , so that after the solder piece 700 passes through the solder piece slot 311 , it can directly enter the solder piece inlet 212 and pass through the discharge slot 211 .

[0068] After determining the position of the end of the welding piece 700, the welding piece pressing cylinder 320 presses the welding piece 700 so that the position of the welding piece 700 can only change together with the welding piece locking mechanism 300, thereby preventing the position of the end of the welding piece 700 from changing during the subsequent operation of the welding piece feeding module, affecting the reliability of the judgment of the end position of the welding piece 700.

[0069] like Figure 1 and Figure 4 As shown, in some embodiments, the solder sheet feeding mechanism 100 includes a solder sheet feeding table 110 and a solder sheet feeding cylinder 120 .

[0070] The solder piece pressing platform 310 is slidably disposed on the solder piece feeding platform 110 along the length direction of the solder piece slot 311 .

[0071] The cylinder body of the solder sheet feeding cylinder 120 is fixed on the solder sheet feeding platform 110, and the piston rod of the solder sheet feeding cylinder 120 is against the solder sheet pressing platform 310, so that after the solder sheet pressing cylinder 320 presses the solder sheet 700, the solder sheet pressing platform 310 is pushed, so that the solder sheet pressing platform 310 drives the solder sheet 700 to move toward the direction close to the discharge platform 210.

[0072] The solder sheet clamping platform 310 can be slidably set on the solder sheet feeding platform 110 along the length direction of the solder sheet groove 311 by setting a slide rail on the solder sheet feeding platform 110 and setting a slide groove on the solder sheet clamping platform 310, and the slide groove and the slide rail are engaged with each other.

[0073] The welding piece pressing platform 310 is slidably arranged on the welding piece feeding platform 110 along the length direction of the welding piece slot 311, so that the welding piece pressing platform 310 can slide relative to the welding piece feeding platform 110. The welding piece feeding cylinder 120 can push the welding piece pressing platform 310, so that the welding piece pressing platform 310 drives the welding piece 700 to move toward the direction close to the discharge platform 210, so that the end of the welding piece 700 can extend from the welding piece outlet 213 for welding the parts to be welded.

[0074] In the above process, since the position of the end of the welding piece 700 has been determined, the pushing stroke of the welding piece feeding cylinder 120 can be adjusted according to the position of the end of the welding piece 700, or, after adjusting the end of the welding piece 700 to a certain position according to the position of the end of the welding piece 700, the welding piece feeding cylinder 120 is controlled to push out a certain stroke, thereby achieving the effect of accurately controlling the length of the welding piece 700 sent out from the welding piece outlet 213.

[0075] like Figure 1As shown, in some embodiments, the welding piece feeding module also includes a workbench 400, and the welding piece feeding table 110 is slidably set on the workbench 400 along the length direction of the welding piece groove 311; the welding piece discharging mechanism 200 is arranged on the welding piece feeding table 110; the welding piece feeding mechanism 100 also includes a platform pushing cylinder 130, the cylinder body of the platform pushing cylinder 130 is fixed on the workbench 400, and the piston rod of the platform pushing cylinder 130 is connected to the welding piece feeding table 110, which is used to push the welding piece feeding table 110 to move, so that the welding piece feeding table 110 drives the welding piece discharging mechanism 200, the welding piece locking mechanism 300 and the welding piece 700 to approach the parts to be welded.

[0076] By adopting the above scheme, when the piston rod of the platform pushing cylinder 130 is pushed out, the welding piece feeding platform 110 can be driven to move. Since the welding piece locking mechanism 300 and the welding piece discharging mechanism 200 are both arranged on the welding piece feeding platform 110, the movement of the welding piece feeding platform 110 can drive the welding piece locking mechanism 300 and the welding piece discharging mechanism 200 to move together. When the welding piece 700 is clamped by the welding piece locking mechanism 300, the welding piece 700 will also move with the welding piece feeding platform 110 in the direction close to the part to be welded, and in this process, the relative positions of the welding piece 700, the welding piece locking mechanism 300 and the welding piece discharging mechanism 200 remain unchanged.

[0077] Through this arrangement, before the end of the welding piece 700 passes through the welding piece outlet 213, the platform pushing mechanism can drive the welding piece 700, the welding piece locking mechanism 300 and the welding piece discharging mechanism 200 to approach the part to be welded. After that, the welding piece 700 only needs to pass through the welding piece outlet 213 for a short distance to enter between the parts to be welded, thereby reducing the probability of the welding piece 700 passing through the welding piece outlet 213 too long and bending, reducing the uncertainty of the position of the end of the welding piece 700, and reducing the welding error rate.

[0078] like Figure 1 and Figure 5 As shown, in some embodiments, the solder sheet feeding module also includes a solder sheet shaping mechanism 500, which includes: a shaping table 510 and a plurality of guide wheels 520, the shaping table 510 is arranged on the side where the solder sheet entrance 212 is located; the plurality of guide wheels 520 are rotatably connected to the shaping table 510, and the plurality of guide wheels 520 are arranged in two rows, and the solder sheet 700 passes between the two rows of guide wheels 520 to straighten the solder sheet 700.

[0079] Optionally, a plurality of guide wheels 520 are provided in each row, and the two rows of guide wheels 520 are staggered with each other, so that the welding sheet 700 can pass straight through between the two rows of guide wheels 520, and the welding sheet 700 can be straightened by the extrusion of the two rows of guide wheels 520.

[0080] Optionally, the shaping table 510 is a vertically arranged plate-like structure, the guide wheel 520 is horizontally arranged on one side of the shaping table 510, and two rows of guide wheels 520 are arranged in the up-down direction. The shaping table 510 can be arranged on the workbench 400 or on the solder sheet feeding table 110, which is not limited in the embodiment of the present application.

[0081] Alternatively, if Figure 1 As shown, the solder sheet feeding module also includes a feeding mechanism 600, which includes a servo motor 610 and a reel 620 connected to the motor shaft of the servo motor 610. The solder sheet 700 is wound on the reel 620. The servo motor 610 rotates in one direction to achieve unwinding, and rotates in the other direction to achieve rewinding.

[0082] The shaping station 510 is disposed between the unwinding mechanism 600 and the solder sheet inlet 212 , and the solder sheet shaping mechanism 500 is the first mechanism that the solder sheet 700 passes through after being unwound from the reel 620 .

[0083] After the soldering sheet 700 is wound off the reel 620, it is often bent, and the bending direction is random, which often makes it difficult to transfer the soldering sheet 700 to the set position. By setting the soldering sheet shaping mechanism 500, the soldering sheet 700 is squeezed by the two rows of guide wheels 520 before entering the soldering sheet entrance 212. The guide wheels 520 can not only play the role of transferring the soldering sheet 700 in a specific direction, but also reduce the bending degree of the soldering sheet 700, so that the soldering sheet 700 is easily transferred to a specific position, which is conducive to the accurate transfer of the soldering sheet 700.

[0084] like Figure 5 and Figure 6 As shown, in some embodiments, the welding piece shaping mechanism 500 also includes: an adjusting block 530, an adjusting screw 540 and an elastic member 550; the adjusting block 530 is slidably mounted on the shaping table 510, wherein a row of guide wheels 520 is mounted on the adjusting block 530; the adjusting screw 540 is connected to the shaping table 510; one end of the elastic member 550 abuts against the adjusting block 530, and the other end abuts against the adjusting screw 540.

[0085] The elastic member 550 is a structure such as a spring or an elastic column.

[0086] A slide rail may be provided on the shaping table 510 , the length direction of the slide rail being parallel to the direction in which the two rows of guide wheels 520 are relatively provided, and a slider is slidably provided on the slide rail.

[0087] Taking the shaping table 510 as an example, in which two rows of guide wheels 520 are arranged relatively to each other in the up and down directions, the slide rail is also arranged in the vertical direction, and the adjustment block 530 is slidably arranged on the slide rail in the vertical direction. A cross beam 560 is arranged above the shaping table 510, and a threaded hole is arranged on the cross beam 560. The threaded hole is located directly above the adjustment block 530, and the adjustment screw 540 is connected in the threaded hole. The elastic member 550 is located between the adjustment block 530 and the adjustment screw 540.

[0088] By adjusting the distance between the adjusting screw 540 and the adjusting block 530, the degree of compression of the elastic member 550 can be changed, thereby changing the force applied by the elastic member 550 on the adjusting block 530, and further changing the distance between the two rows of guide wheels 520 or changing the pressure of the two rows of guide wheels 520 on the welding sheet 700, so that the guide wheels 520 are suitable for shaping welding sheets 700 of various thicknesses or hardnesses.

[0089] Optionally, a positioning hole 531 is provided above the adjusting block 530 , a positioning step 541 is provided on the adjusting screw 540 , and one end of the elastic member 550 abuts in the positioning hole 531 , and the other end abuts on the positioning step 541 .

[0090] An embodiment of the present application further discloses a welding device, comprising the welding sheet feeding module in any of the above embodiments.

[0091] When the welding sheet feeding module welds parts, the welding quality is stable and it is not easy to cause waste of the welding sheet 700.

[0092] To summarize, the soldering piece delivery module of the embodiment of the present application is equipped with a detection component 220. The detection component 220 can detect the two positions of the material trough 211, and determine whether there are soldering pieces 700 at these two positions, thereby further inferring the position of the end of the soldering piece 700 relative to the two detected positions. According to the position of the end of the soldering piece 700, it is convenient to relatively accurately control the length of the soldering piece 700 delivered from the soldering piece outlet 213, thereby reducing the cost waste or welding quality problems caused by the different lengths of the soldering pieces 700, thereby achieving the purpose of saving costs and ensuring the stability of the quality of welding products.
