Description

Technical Field

[0001] The utility model relates to the technical field of solar cell welding, in particular to a solar cell flip welding device. Background Art

[0002] When solar panels are produced, multiple small cells are welded together by welding rods. After multiple small cells are arranged in an orderly pattern, they are welded into a flat structure with welding rods to form a solar cell. During the welding process, a welding device is required.

[0003] For example, the Chinese patent authorization announcement number is CN219966826U, "discloses a solar cell welding device, including an upper equipment box and a lower equipment box, the upper equipment box and the lower equipment box are hinged at the back, and the lower equipment box is internally connected with an operating table";

[0004] In the above-mentioned comparative documents, an air cooler and a cooling tube can be used to accelerate the cooling of the welding head after a long period of work, and the battery cells and welding rods only need to be placed on the operating table, without manual hand-held operation, thus reducing the manual load and preventing burns;

[0005] However, in the actual welding process of the above-mentioned solar cells, when multiple groups of small solar cells and welding rods are placed in matching grooves on the operating table, there is a lack of positioning mechanism for the solar cells and welding rods. During the mobile welding process, the welding head is easy to touch the solar cells and welding rods, causing the placement to shift, and there is desoldering between the solar cells. In addition, the solar cells and welding rods need to be turned over after welding. When performing secondary welding, the solar cells formed on the front side need to be turned over manually, which is easy to burn the workers' hands and is extremely inconvenient to operate. Utility Model Content

[0006] The utility model aims to provide a solar cell flip welding device, which can realize the preliminary positioning of multiple groups of solar cells and welding rods after being placed, so as to facilitate the integrated welding of solar cells, and can flip the solar cells as a whole after one welding, without manual flipping, and is convenient to operate.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a solar cell flip welding device, comprising an equipment box, an operating table, and a welding mechanism, a welding table is fixedly installed on the top of the operating table, and a cell limiting groove and a welding rod limiting groove matching the welding mechanism are respectively opened on the top of the welding table, and an adsorption positioning hole is opened on the top of the welding table, electric slides are symmetrically fixedly installed on both sides of the inner wall of the equipment box, and a slider is slidably connected inside the electric slide, and clamping plates are symmetrically arranged on both sides of the inner wall of the welding table, an air pump is fixedly installed on the back of the operating table, and an electric turntable and a clamping cylinder are respectively installed on the outside of the slider, and the telescopic end of the clamping cylinder is fixedly connected to the clamping plate on the same side.

[0008] Preferably, a control panel is installed on one side of the front of the equipment box.

[0009] Preferably, the welding platform is a rectangular structure with an open top, and the bottom of the welding platform is a cavity structure, and the adsorption positioning hole is connected to the cavity at the bottom of the welding platform.

[0010] Preferably, the air pump is connected to the bottom cavity of the welding table through an air pipe.

[0011] Preferably, the welding mechanism comprises an adjusting motor, an adjusting telescopic rod and a welding head, and the welding head corresponds one-to-one to the plurality of groups of battery cell limiting grooves.

[0012] Preferably, the length of the clamping plate matches the width of the inner wall of the welding table, the electric turntable is fixedly mounted on the matching sliding block on the outer side of the electric slide table, and the clamping cylinder is fixedly mounted on the output end of the electric turntable.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The battery cells and welding rods in the utility model are placed at the corresponding battery cell limiting grooves and welding rod limiting grooves on the top of the welding table, and the air pump can be used to generate negative pressure in the cavity at the bottom of the welding table, so that the battery cells and welding rods can be firmly positioned in the limiting grooves. In this way, when the welding head performs criss-cross welding on multiple groups of battery cells and welding rods in the horizontal and vertical directions, it can be avoided that the welding head touches and shifts the battery cells and welding rods in the limiting grooves, causing the welding gap to desolder, thereby ensuring that the battery cells and welding rods arranged in a criss-cross manner during the welding process can be firmly positioned in the limiting grooves, making the welding of the solar cell more complete, and solving the problem of lack of battery cell and welding rod positioning mechanism between multiple groups of battery cells and welding rods. In the process of mobile welding, the welding head is easy to touch the battery cells and welding rods, causing the placement to shift, and there is a problem of desoldering in the welding between the battery cells;

[0015] In the utility model, after the battery cell and the top surface of the electrode are welded and formed once by the welding mechanism, the air pump can stop applying negative pressure to the cavity at the bottom of the welding table. At this time, the clamping cylinder, the electric turntable and the electric slide can cooperate with each other to clamp the formed battery cell with the clamping plates on both sides of the inner wall of the welding table, and after rising away from the welding table, it rotates one circle to turn over and re-enters the welding table. In this way, the bottom surface of the battery cell formed once can be welded and formed for the second time by the welding mechanism, thereby achieving complete welding of both sides of the solar cell. During the secondary welding, there is no need to manually turn over, and the operation is convenient. This solves the problem that when the bottom surface of the once-formed battery cell is welded for the second time, the battery cell formed on the front side needs to be turned over manually, which can easily burn the workers' hands and is inconvenient to operate.

The battery cell and the welding rod are moved and welded by the welding head, which is a prior art solution and will not be described in detail here.

[0025] The battery cells and welding rods are placed at the corresponding battery cell limiting grooves 41 and welding rod limiting grooves 42 on the top of the welding table 4. The air pump 7 can generate negative pressure on the cavity at the bottom of the welding table 4, so that the battery cells and welding rods can be firmly positioned in the limiting grooves. In this way, when the welding head performs criss-cross welding on multiple groups of battery cells and welding rods in the horizontal and vertical directions, it can be avoided that the welding head touches and shifts the battery cells and welding rods in the limiting grooves, causing the welding gap to be desoldered, thereby ensuring that the battery cells and welding rods arranged in a criss-cross manner during the welding process can be firmly positioned in the limiting grooves, so that the welding and forming of the solar cell cells are more complete;

[0026] After the battery cell and the top surface of the welding rod are welded and formed once by the welding mechanism 3, the air pump 7 can stop applying negative pressure to the cavity at the bottom of the welding table 4. At this time, the clamping cylinder 9 cooperates with the electric turntable 8 and the electric slide 5 to clamp the formed battery cell with the clamping plates 6 on both sides of the inner wall of the welding table 4, and after rising away from the welding table 4, it rotates one circle to turn over and re-enters the welding table 4. In this way, the bottom surface of the once formed battery cell can be welded and formed for the second time by the welding mechanism 3, thereby achieving complete welding of both sides of the solar cell. During the second welding, there is no need for manual turning over, and the operation is convenient.

[0027] A control panel 11 is installed on the front side of the equipment box 1, and a PLC controller is electrically connected between the control panel 11 and the welding mechanism 3, the air pump 7, the electric turntable 8, the clamping cylinder 9 and the electric slide 5;

[0028] Among them, the welding table 4 is a rectangular structure with an open top, and the bottom of the welding table 4 is a cavity structure, the adsorption positioning hole 43 is connected to the cavity at the bottom of the welding table 4, the air pump 7 is connected to the cavity at the bottom of the welding table 4 through an air pipe, the welding mechanism 3 includes an adjusting motor, an adjusting telescopic rod and a welding head, and the welding head corresponds one by one to multiple groups of battery cell limiting grooves 41, the battery cells and the welding rods are placed in the corresponding battery cell limiting grooves 41 and the welding rod limiting grooves 42 at the top of the welding table 4, and the air pump 7 can be used to apply negative pressure to the cavity at the bottom of the welding table 4, so that the battery cells and the welding rods can be firmly positioned in the limiting grooves.

After the battery cells and the top surfaces of the welding rods arranged in the limiting grooves of the welding table 4 are welded once, the clamping cylinder 9 can cooperate with the electric turntable 8 and the electric slide 5 to clamp the formed battery cells on both sides of the inner wall of the welding table 4, and after rising away from the welding table 4, it rotates one circle to turn over and re-enters the welding table 4, so that the bottom surface of the once-formed battery cell can be welded for the second time through the welding mechanism 3.

[0030] Working principle: When welding multiple groups of battery cells and welding rods, first place the battery cells and welding rods in the corresponding battery cell limiting grooves 41 and welding rod limiting grooves 42 to form a mesh structure;

[0031] Then, the air pump 7 can be used to generate negative pressure in the bottom cavity of the welding table 4, so that the battery cells and welding rods can be firmly positioned in the limiting grooves. In this way, when the welding head performs criss-cross welding on multiple groups of battery cells and welding rods in the horizontal and vertical directions, it can prevent the welding head from touching and shifting the battery cells and welding rods in the limiting grooves, causing the welding gap to be desoldered;

[0032] After the battery cell and the top surface of the welding rod are welded and formed once by the welding mechanism 3, the air pump 7 can stop applying negative pressure to the cavity at the bottom of the welding table 4;
