Description

Technical Field

[0001] This utility model relates to the field of clamping, specifically to a welding strip clamping assembly for a string welding machine. Background Technology

[0002] With the rapid development of the new energy industry and the technological advancements in solar photovoltaic modules, the solder ribbons used to connect the cells are becoming increasingly dense and thinner in order to achieve more efficient and lower-cost module manufacturing processes. A problem arises when the solder ribbons are pulled, straightened, and placed in the stringing machine; they are prone to jumping or being pulled by the grippers when they open. This leads to inaccurate placement of the solder ribbons, resulting in exposed areas, incomplete soldering, module defects, reduced power output, and even module failure.

[0003] When soldering strips onto the back of solar cells, existing grippers open in a single motion, resulting in a large range of motion and making it easy for the solder strip to deviate. The guide groove is also short, causing the solder strip to shift or fail to enter the gripping range. Therefore, this invention provides a solder strip clamping assembly for a string welding machine. Utility Model Content

[0004] The purpose of this invention is to provide a welding strip clamping assembly for a string welding machine to solve the problem mentioned in the background art where the welding strip is driven when the clamps are opened.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A welding strip clamping assembly for a string welding machine includes a guide plate, a driving component, a sliding component, a first reversing assembly, and a second reversing assembly. The upper side of the guide plate has multiple guide slots for the welding strip to pass through. The driving component is used for double-stroke driving. The driving component, sliding component, first reversing assembly, and second reversing assembly are all disposed on the lower side of the guide plate. The driving component is fixedly connected to the guide plate, and the driving end of the driving component is fixedly connected to the sliding component. The sliding component is fixedly connected to the guide plate, and a pair of reversing slots are formed in the middle of the sliding component. First reversing assembly and second reversing assembly are slidably connected within the pair of reversing slots.

[0007] It also includes clamping component one and clamping component two; clamping component one and clamping component two are disposed at the ends of the guide groove plate along the width direction, and clamping component one and clamping component two are respectively fixedly connected to a pair of reversing components two and reversing components one.

[0008] Preferably, clamping component one includes a clamping plate and multiple fixing claws. Multiple evenly distributed fixing claws are fixedly connected to the side of the clamping plate away from the sliding component, and a reversing component two is fixedly connected to the lower side of the clamping plate.

[0009] Preferably, the clamping component two includes a clamping rod located on the lower side of the clamping plate and a plurality of elastic claws, the plurality of elastic claws being fixedly connected to the clamping rod and extending upward between adjacent fixed claws; the clamping rod is fixedly connected to the reversing component one.

[0010] Preferably, the elastic claw is made of an elastic material at least in the part used for clamping.

[0011] Preferably, the sliding member includes a deflector plate and a pair of fixing members; the deflector plate is fixedly connected to the driving member; the end of the deflector plate near the driving member extends to both sides, and the extended part is slidably connected to the pair of fixing members; the fixing members are fixedly connected to the lower side of the guide plate.

[0012] Preferably, a pair of deflection slots are formed inside the deflection plate; the deflection slots extend toward the end of the drive member and also tilt toward both sides of the deflection plate to form slots with an arc-shaped path.

[0013] Preferably, the first deflection assembly includes a pair of deflector components; the second deflection assembly includes a pair of deflector components; the pair of deflector components and the pair of deflector components are arranged at intervals; the deflector components 1 and 2 located adjacent to each other in the middle extend toward the upper side of the deflection groove; the extended portions of the deflector components 1 and 2 are fixedly connected with bolts; the bolts are placed in the deflection groove.

[0014] Preferably, a sliding rod is fixedly connected to the lower side of the guide plate, and a pair of deflector one and a pair of deflector two are slidably connected to the sliding rod.

[0015] Preferably, each deflector 1 has a clamp rod fixedly connected to the side away from the deflector slot; and the upper side of each deflector 2 protrudes upward and is fixedly connected to the clamp plate.

[0016] Compared with existing technologies, the advantages of this invention are: the driving component is a dual-stroke driving component, which can open in two stages when opening the clamp on the welding strip. First, the movement distance of the fixed claw and the elastic claw is reduced when they move away from each other, opening slightly to ensure that the welding strip can be pulled out after straightening. Then, it is fully opened to ensure smooth pulling of the welding strip in the next operation, thus ensuring the stability of the welding strip throughout the entire feeding process. This avoids the problem of jumping and pulling during the pulling, straightening, and placement of the welding strip, which could lead to strip deviation.

[0017] Directional change is achieved through the cooperation of a deflector plate, an inclined deflector groove, deflector component one, deflector component two, clamping component one, and clamping component two. The linear movement of the deflector plate forces deflector component one and deflector component two to tilt along the deflector groove, thereby changing the movement direction of clamping component one and clamping component two to lateral movement. The staggered arrangement of the fixed claw and the elastic claw allows the fixed claw and the elastic claw to move closer together to clamp the weld strip, or to move away from each other to release the clamping of the weld strip.

Detailed Implementation

[0029] Example 1:

[0030] Please see Figure 1-10 This utility model provides a technical solution: such as Figures 1-3 As shown, a welding strip clamping assembly for a string welding machine includes a guide plate 1, a driving component 3, a sliding component 4, a first reversing component 6, and a second reversing component 7. The upper side of the guide plate 1 has multiple guide slots 11 for the welding strip to pass through.

[0031] The drive component 3, the sliding component 4, the first steering assembly 6, and the second steering assembly 7 are all located on the lower side of the guide plate 1. The drive component 3 is capable of two-stroke driving, and the drive component 3 is preferably a cylinder.

[0032] The driving component 3 is fixedly connected to the guide plate 1, and the driving end of the driving component 3 is fixedly connected to the sliding component 4; the sliding component 4 is fixedly connected to the guide plate 1, and a pair of reversing grooves 411 are provided in the middle of the sliding component 4; the reversing component 1 6 and the reversing component 2 7 are respectively slidably connected in the pair of reversing grooves 411.

[0033] It also includes clamping component 1 21 and clamping component 22; clamping component 1 21 and clamping component 22 are disposed at the ends of the guide plate 1 along the width direction and are used to clamp the welding strip from the guide groove 11.

[0034] The second deflector assembly 7 and the first deflector assembly 6 are fixedly connected to the first clamping member 21 and the second clamping member 22, respectively, and are used to drive the first clamping member 21 and the second clamping member 22 to move along the path of the deflector groove 411. The first clamping member 21 and the second clamping member 22 are arranged crosswise and there is a distance between them.

[0035] like Figures 2-3 As shown, clamping component 21 includes a clamping plate 211 and multiple fixing claws 212. The side of the clamping plate 211 away from the guide plate 1 is fixedly connected to the multiple fixing claws 212. The multiple fixing claws 212 are evenly distributed on the side of the clamping plate 211, and clamping grooves 213 are formed between adjacent fixing claws 212. A reversing assembly 7 is fixedly connected to the lower side of the clamping plate 211.

[0036] Clamping component 22 includes a clamping rod 221 and multiple elastic claws 222. The clamping rod 221 is located below the clamping plate 211. One end of each elastic claw 222 is uniformly fixedly connected to the clamping rod 221, and the other end extends into the clamping groove 213. The elastic claws 222 are made of elastic material, at least in the portion extending into the clamping groove 213, allowing for slight elastic deformation during clamping to eliminate machining errors and ensure the welding strip is clamped. The clamping rod 221 is fixedly connected to the reversing assembly 6.

[0037] like Figures 4-7 As shown, the sliding member 4 includes a deflector plate 41 and a pair of fixing members 42. A deflector groove 411 is formed on the deflector plate 41, and the end of the deflector plate 41 away from the deflector groove 411 is fixedly connected to the driving end of the driving member 3; the end of the deflector plate 41 near the driving member 3 extends to both sides for sliding connection with the pair of fixing members 42. The fixing members 42 are fixedly connected to the lower side of the guide plate 1.

[0038] like Figures 7-10 As shown, the first steering assembly 6 includes a pair of steering members 51. The second steering assembly 7 includes a pair of steering members 52. The pair of steering members 51 and the pair of steering members 52 are arranged at intervals. The adjacent steering members 51 and 52 located in the middle extend further from the side of the steering groove 411 to the upper side of the steering groove 411; the extended portions of the steering members 51 and 52 are fixedly connected with bolts. The bolts are placed in the steering groove 411 for sliding within the steering groove 411. The side of the clamping rod 221 away from the elastic claw 222 is fixedly connected to the side of the pair of steering members 51 away from the steering groove 411. The upper side of the pair of steering members 52 protrudes upward and is fixedly connected to the lower side of the clamping plate 211.

[0039] A pair of deflection slots 411 extend toward the end of the drive member 3 and also tilt toward both sides of the deflection plate 41, forming slots with an arc-shaped path (see...). Figure 7 When the deflector plate 41 moves, it drives the deflector component 1 51 and deflector component 2 52, which have extended portions, to move laterally within the deflector groove.

[0040] A sliding rod 53 is fixedly connected to the lower side of the guide plate 1. The sliding rod 53 is slidably connected to the upper side of both the first pair of deflector 51 and the second pair of deflector 52.

[0041] There is a distance between adjacent deflector 1 51 and deflector 2 52. The side of deflector 2 52 away from the deflector groove 411 is at a distance from the clamping rod 221. The upper side of deflector 1 51 is at a distance from the clamping plate 211, so as to facilitate the movement of deflector 1 51 and deflector 2 52 for clamping or opening.

[0042] Working principle: With the fixed claw 212 and elastic claw 222 fully open, the guide groove 11 and clamping groove 213 are connected. The welding strip moves through the guide groove 11 into the clamping range of the fixed claw 212 and elastic claw 222. When the tail of the welding strip passes the fixed claw 212 and elastic claw 222, the welding strip is clamped. First, the driving component 3 drives the deflector plate 41 to move away from the driving component 3. During the movement, the pair of deflector grooves 411 of the deflector plate 41 force the adjacent deflector component 1 51 and deflector component 2 52 to slide along the arc-shaped path of the deflector grooves 411. During the sliding process, the distance between the adjacent deflector component 1 51 and deflector component 2 52 gradually increases, thereby realizing the lateral movement of deflector component 1 51 and deflector component 2 52. Simultaneously, the first deflector 51 moves the clamping rod 221 and the elastic claw 222; the second deflector 52 moves the clamping plate 211 and the fixed claw 211, causing each pair of adjacent fixed claws 212 and elastic claws 222 to gradually move closer together to clamp the welding strip and straighten it. The straightened welding strip undergoes slight plastic deformation. Due to this deformation, the welding strip can remain straight without being stretched, thus adhering to the grid lines on the solar cell. Then, the clamping of the welding strip is released.

[0043] The process of releasing the welding strip is as follows: First, a gradual release is performed, that is, the driving component 3 moves in the first stroke. The first stroke is a short stroke. Specifically, the driving component 3 drives the deflector plate 41 to move towards the driving component 3. The corresponding deflector 1 51, deflector 2 52, clamping component 1 21, and clamping component 2 22 move in opposite directions, so that each pair of adjacent fixed claws 212 and elastic claws 222 gradually move away from each other, thereby releasing the clamping of the welding strip. The opening movement path is opposite to the above clamping movement path. At this time, the opening range is small, and the welding strip is hardly moved along, so the welding strip can be pulled forward in a straight line. After the welding strip is pulled forward away from the fixed claws 212 and elastic claws 222, the driving component 3 drives the deflector plate 41 to move further towards the driving component 3, which is the second stroke of the driving component 3. This allows the fixed claw 212 and the elastic claw 222 to fully open, so that the welding strip can smoothly enter the fixed claw 212 and the elastic claw 222 to clamp the welding strip again during the next feeding.
