Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic assembly manufacturing, in particular to a welding strip receiving plate and a welding strip limiting device. Background Art

[0002] When preparing photovoltaic modules in strings, two adjacent cells are often connected by welding ribbons to form a corresponding string structure. In order to realize the continuous preparation of photovoltaic module cell strings, it is usually necessary to quickly prepare multiple weld ribbons pulled out into multiple weld ribbon groups, and for this purpose, it is also necessary to set up corresponding weld ribbon pulling-out mechanisms, clamping mechanisms, weld ribbon cutting mechanisms, weld ribbon carriers, etc. Among them, the clamping mechanism is used to clamp the weld ribbon in the non-pulling state to facilitate the pushing of the weld ribbon group.

[0003] The currently used solder ribbon pull-out mechanism and solder ribbon carrier are prone to deviate from the positioning position of the solder ribbon carrier when the solder ribbon moves with the pull-out action, causing the solder ribbon on the solder ribbon carrier to be skewed; when taking the solder ribbon, the tilted solder ribbon will be directly transferred to the feeding position, which is likely to cause welding disconnection and deviation, which is not conducive to normal stringing. Summary of the invention

[0004] The utility model aims to provide a welding strip receiving plate and a welding strip limiting device, which can effectively prevent the welding strip from deviating, thereby ensuring a stable supply of the welding strip.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0007] The second positioning block is further provided with a guide channel, and the lower end of the guide channel is smoothly connected to the groove.

[0008] Furthermore, two guide protrusions are convexly provided on the top surface of the second positioning block, and the two guide protrusions are respectively arranged on both sides of the groove to form the guide channel.

[0009] Furthermore, the length of the guide protrusion on the same second positioning block is smaller than the length of the groove.

[0010] Furthermore, the cross-section of the first positioning block and the second positioning block along the second direction is a structure that is narrow at the top and wide at the bottom.

[0011] Furthermore, the second positioning block is arranged close to the welding strip side of the plate body.

[0012] Furthermore, the adsorption holes are in the shape of elongated strips along the second direction.

[0013] A solder strip limiting device comprises the above-mentioned solder strip receiving plate, a mounting plate located above the solder strip receiving plate and at least one limiting component arranged on the mounting plate, wherein the limiting component can cooperate with each of the guide channels arranged along the first direction to limit each solder strip in a solder strip group within the corresponding solder strip positioning groove.

[0014] Furthermore, the limiting assembly includes a lifting frame, a pressure strip and a lifting drive; the lifting frame is located between the welding strip receiving plate and the mounting plate; the pressure strip is connected to the bottom surface of the lifting frame, and the bottom surface of the pressure strip is provided with a plurality of limiting protrusions, and the limiting protrusions are slidably matched with the corresponding guide channels up and down; the lifting drive drives the lifting frame to rise and fall relative to the mounting plate.

[0015] Furthermore, the lifting frame is connected to two vertical guide slide posts, the guide slide posts are slidably connected to guide sleeves, and the guide sleeves are connected to the mounting plate.

[0016] Furthermore, a group of limiting blocks for limiting the position of the pressure strip are arranged on the plate body.

[0017] The beneficial effects of the utility model are:

[0018] 1. By forming a welding strip positioning groove through a plurality of grooves arranged at intervals along the second direction, the welding strip can be accurately positioned and guided; by setting a guide channel on the second positioning block, the welding strip can be easily entered into the corresponding groove.

[0019] 2. The limiting protrusions on the bottom surface of the pressure strip enter the corresponding guide channels respectively to limit the welding strip in the groove, so that the welding strip can still be reliably positioned on the welding strip receiving plate after being pulled out, thereby ensuring a stable supply of welding strips, which is conducive to the normal advancement of the stringing process.

[0028] Specifically, two guide protrusions 31 are convexly disposed on the top surface of the second positioning block 3, and the two guide protrusions 31 are disposed on both sides of the groove 4 to form a guide channel 6. The plate body 1, the first positioning block 2, the second positioning block 3 and the guide protrusions 31 are integrally formed.

[0029] In this embodiment, the adsorption holes 5 are in the shape of long strips along the second direction, so as to realize firm adsorption and fixation of the welding strip in the groove 4 under vacuum negative pressure operation.

[0030] In this embodiment, the length of the guide protrusion 31 on the same second positioning block 3 is smaller than the length of the groove 4; in order to facilitate observation of whether the welding strip is located in the groove 4, the two ends of the groove 4 can expose the two end sides of the two guide protrusions 31.

[0031] In this embodiment, the cross-section of the first positioning block 2 and the second positioning block 3 along the second direction is narrow at the top and wide at the bottom. On the one hand, it can ensure its stable connection with the plate body 1, and on the other hand, it can reduce the contact between the welding strip and the first positioning block 2 and the second positioning block 3, thereby reducing the resistance of pulling the strip.

[0032] In this embodiment, the second positioning block 3 is disposed close to the welding strip side of the plate body 1 .
