Description

Technical Field

[0001] The present invention relates to the technical field of solar cell processing equipment, and in particular to a cell welding and loading device. Background Art

[0002] Solar cells, also known as "solar chips" or "photovoltaic cells," are thin sheets of photovoltaic semiconductors that directly generate electricity from sunlight. When exposed to light that meets certain illumination conditions, they can instantly output voltage and, if a circuit is connected, generate current. Solar cells directly convert light energy into electricity through the photoelectric or photochemical effect. During the production process, multiple groups of solar cells are stacked and placed in storage racks, where they are then loaded from top to bottom. A robotic arm connected to a suction cup removes the cells from the racks under the suction force of the cup. During the stacking process, cells tend to stick together, making it difficult for the suction cup to pick up the top cell. In addition, the suction cup may not only pick up the top cell, but also absorb both cells at once, disrupting normal production. Furthermore, existing cell separation devices typically use pointed components to support the separation, which can damage the cells and reduce yield. Summary of the Invention

[0032] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that it is easy for a person skilled in the art to implement these embodiments. However, the present invention can also be implemented in various different forms. Therefore, the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, parts that are not connected to the present invention will be omitted from the accompanying drawings.

[0033] like Figure 1 、 2 As shown, a battery cell welding and feeding device includes: a supporting part 1, a fixing part 2, a limiting part 3, and a separating part 4;

[0034] like Figure 3 As shown, the support part 1 includes: a support plate 11 and a support rod 12;

[0035] The support rod 12 is located on the ground and is used to support the support plate 11;

[0036] The support plates 11 are located above the support rods 12 and fixed to each other, and are used to support and fix some components in the fixing portion 2 and the limiting portion 3;

[0037] like Figure 3 As shown, the fixing part 2 includes: a fixing shell 21, a rotating fixing rod 22, and a fixing groove 23;

[0038] The fixed housing 21 is located on the support plate 11 and is fixedly connected to each other. Two sets of sliding grooves are provided on the left and right inner walls of the fixed housing 21 to provide a track for the sliding of the separation part 4 and to support the rotating fixed rod 22 and the fixed groove 23.

[0039] The rotating fixing rod 22 is located on the front end plate surface of the fixed housing 21 and is rotatably connected to each other, and is used to limit the sliding plate 34 through the rotating fixing rod 22 and the fixing groove 23;

[0040] The fixing groove 23 is located on the right side of the rotation fixing rod 22 and is connected to the limiting sliding plate 34 for sliding up and down. The fixing groove 23 and the rotation fixing rod 22 are nested and fixed with each other to achieve the purpose of limiting the sliding plate 34.

[0041] like Figure 14 As shown, the rotating fixed rod 22 includes: a rotating rod 221, a cylindrical slide rail 222, a sliding portion 223, a restricted rod 224, a limiting hole 225, and an extrusion rail 226;

[0042] The rotating rod 221 is located on the front end panel of the fixed housing 21 and passes through the front end panel of the fixed housing 21. The rotating rod 221 is L-shaped and consists of a vertical straight plate and a cylindrical horizontal plate. The vertical straight plate can be extended and retracted, and can be locked by rotating to accommodate the cylindrical slide rail 222 and the limit hole 225.

[0043] The cylindrical slide rail 222 is provided on the cylindrical plate surface of the rotating rod 221, and the cylindrical slide rail 222 provides a track for the sliding portion 223 to slide;

[0044] The sliding portion 223 is located on the cylindrical slide rail 222 and abuts against each other, and is used to support the limiting rod 224;

[0045] The limiting rod 224 is located at the upper end of the sliding portion 223. The sliding portion 223 and the limiting rod 224 are connected by a spring. The lower end of the spring is fixedly connected to the limiting rod 224, and the upper end is fixedly connected to the sliding portion 223. The spring spatially limits the limiting rod 224. When the rotating rod 221 is rotated, the rotating rotating rod 221 drives the sliding portion 223 on the cylindrical slide rail 222 to rotate. The sliding portion 223 rotating to the right enters the track of the extrusion rail 226, and then during the movement, the rotating sliding portion 223 is squeezed by the track of the extrusion rail 226, causing the limiting rod 224 to move downward, and then the lower end of the limiting rod 224 enters the limiting hole 225 to complete the self-locking.

[0046] The limiting hole 225 is located directly below the limiting rod 224 and is used to control the limiting rod 224;

[0047] The extrusion rail 226 is located on the fixed housing 21 and is in a contracted arc shape, and is used to limit the spatial position of the limiting rod 224;

[0048] like Figure 4-11 As shown, the limiting part 3 includes: a support column 31, a bottom plate 32, a chute portion 33, a limiting sliding plate 34, an extension groove 35, a limiting vertical plate 36, a hydraulic telescopic rod 37, a limiting spring 1 38, a supporting telescopic rod 39, a sliding base 310, a chute 311, a connecting rope 312, a squeezing plate 313, a limiting spring 2 314, a fixing hole 315, a fixed support plate 316, a limiting spring 317, and a fixing column 318;

[0049] The support columns 31 are located above the support plate 11 and are fixedly connected to each other to support the bottom plate 32;

[0050] The bottom plate 32 is located above the support column 31 and is fixedly connected to each other, and is used to support and accommodate the slide groove portion 33, the extension groove 35, the limiting spring 38, the supporting telescopic rod 39, the sliding base 310, and the slide groove 311;

[0051] The slide groove portion 33 is located in the middle of the bottom plate 32 and can slide up and down along the bottom plate 32 to drive the limiting sliding plate 34 to move up and down;

[0052] The hydraulic telescopic rod 37 is located below the chute portion 33 and is fixedly connected to each other. At the same time, the lower end of the hydraulic telescopic rod 37 is fixedly connected to the support plate 11 to drive the chute portion 33 to move up and down;

[0053] The limiting sliding plate 34 is located inside the chute portion 33 and is slidably connected. Since the chute portion 33 is fixed to the upper end surface of the hydraulic telescopic rod 37, the sliding plate 34 is limited to slide inside the chute portion 33 and does not completely leave the chute portion 33. The front end surface of the limiting sliding plate 34 is provided with a chute to accommodate the fixed groove 23 to move up and down in the chute. When a new battery cell stack needs to be placed, the limiting sliding plate 34 is pulled. At this time, the chute portion 33 is fixed, and then a new battery cell stack is placed on the limiting sliding plate 34. Then, the limiting sliding plate 34 is pushed to drive the battery cell stack into the top of the bottom plate 32.

[0054] The extension slots 35 are located on the left and right sides of the limiting sliding plate 34. The extension slots 35 are distributed in two groups on the left and right sides, and are used to limit the movement of the vertical plate 36 and accommodate the limiting spring 38, the supporting telescopic rod 39, and the sliding base 310.

[0055] The sliding grooves 311 are located on the left and right sides of the extension groove 35 and are used to provide a track for the sliding base 310 to slide;

[0056] The sliding base 310 is located inside the sliding groove 311 and the extension groove 35, and is used to support and fix the limiting vertical plate 36;

[0057] The limiting spring 1 38 is located inside the extension groove 35. One end of the limiting spring 1 38 is fixed to the sliding base 310, and the other end is fixed to the tail plate of the extension groove 35 to limit the movement trajectory of the sliding base 310.

[0058] The supporting telescopic rod 39 is located inside the limiting spring 1 38. One end of the supporting telescopic rod 39 is fixed to the sliding base 310, and the other end is fixed to the tail plate surface of the extension slot 35, for supporting the limiting spring 1 38.

[0059] The limiting vertical plates 36 are located above the sliding base 310 and are fixed to each other. The limiting vertical plates 36 are L-shaped plates and are used to fix and limit the battery stack.

[0060] The extrusion plate 313 is located on the inner side of the L-shaped plate surface of the limiting vertical plate 36. The extrusion plate 313 is tilted and set at the corner of the L-shaped plate surface of the limiting vertical plate 36. It is used to push the limiting sliding plate 34 to move toward the rear end surface of the slide groove portion 33 after the new battery cell is placed. During the movement, the battery cell stack squeezes and pushes the limiting vertical plate 36 to move along the track slide groove 311 inside the extension groove 35. When the distance between the two sets of limiting vertical plates 36 is consistent with the size of the battery cell, the battery cell stack no longer squeezes the edge of the limiting vertical plate 36, but presses against the inner plate of the limiting vertical plate 36. At the same time, the limiting spring 1 38 presses the sliding base 310, causing the limiting vertical plate 36 to be fixed, thereby squeezing the squeezing plate 313, causing the squeezing plate 313 to move backward. The backward squeezing plate 313 squeezes the limiting spring 2 314, causing the limiting spring 2 314 to loosen its support for one end of the connecting rope 312, causing the connecting rope 312 to move backward. Then, the limiting spring 317 drives the fixing column 318 to enter the fixing hole 315, completing the sliding base 310, thereby achieving the fixation of the battery cell stack;

[0061] The connecting rope 312 is located between the extrusion plate 313 and the fixing column 318, and is used to transmit the power of the extrusion plate 313 to control the retraction and extension of the limiting spring 317;

[0062] The second limiting spring 314 is located between the extrusion plate 313 and the limiting vertical plate 36 and is fixedly connected to each other, and is used to control the spatial position of the extrusion plate 313;

[0063] The fixed support plate 316 is located on one side of the sliding base 310 close to the extension groove 35 and is fixedly connected to each other, and is used to support and fix the limiting spring 317;

[0064] The limiting spring 317 is located between the fixed support plate 316 and the fixed column 318 and is fixedly connected to each other, and is used to limit the spatial position of the fixed column 318;

[0065] The fixing post 318 is located on a side of the limiting spring 317 away from the fixed support plate 316 and is fixedly connected to each other, and is used to enter and exit the fixing hole 315 through the space of the limiting spring 317;

[0066] The fixing hole 315 is located on the inner side of the slide groove 311, and is used for the fixing column 318 and the fixing hole 315 to cooperate with each other to form a fixed

[0067] like Figure 9 、 10 As shown, the limiting vertical plate 36 includes: a main plate 361 and a limiting groove 362;

[0068] The main plate 361 is located above the sliding base 310 and is fixedly connected to each other, and is used to limit the battery stack and accommodate the limiting groove 362;

[0069] The limiting groove 362 is located at the top of the main plate 361, and the limiting groove 362 is used to be nested with the sleeve block 414 to form a fixed position, thereby limiting the linkage between the vertical plate 36 and the separation device 41;

[0070] like Figure 12 As shown, the separation part 4 includes: a separation device 41, an electric telescopic rod 42, a connecting and fixing rod 43, and a separation line 44;

[0071] The separation device 41 is located on the inner panel of the fixed shell 21. The separation device 41 is distributed on the left and right side panels of the separation device 41 and is divided into two groups on the left and right, with two cells in each group, one in front and one in the back. The front separation device 41 is fixedly connected to the fixed shell 21, and the rear separation device 41 is slidably connected to the fixed shell 21. After the separation line 44 separates the bonded battery cells, the separation device 41 is inserted between the two groups of battery cells to form a gap, so that the two groups of battery cells can be bonded again and the battery cells below can be restricted at the same time.

[0072] The connecting and fixing rod 43 is located between the two separation devices 41 on one side and is fixedly connected to each other. The connecting and fixing rod 43 can be extended and retracted to synchronize the extension lengths of the two separation devices 41;

[0073] The electric telescopic rods 42 are located on the rear end panel of the fixed housing 21 and are fixedly connected to each other. The electric telescopic rods 42 are divided into two groups, left and right, for driving the separation line 44 to move;

[0074] The separation line 44 is located between the two sets of electric telescopic rods 42 and is used to separate the battery cells.

[0075] like Figure 13 As shown, the separation device 41 includes: a sliding telescopic rod 411, a limit spring 412, a telescopic triangular plate 413, and a sleeve block 414;

[0076] The sliding telescopic rod 411 is located on the inner side of the fixed housing 21. The sliding telescopic rod 411 can be extended and retracted forward and backward to achieve a change in length. The sliding telescopic rod 411 can then slide on the slideways provided on the left and right inner walls of the fixed housing 21. A groove is provided on the sliding telescopic rod 411. The sliding telescopic rod 411 is used to adapt to the separation of battery cells of various sizes.

[0077] The limiting spring 412 is located in the groove at the front end of the sliding telescopic rod 411 and is fixedly connected to each other, and is used to limit the spatial position of the telescopic triangle plate 413;

[0078] The telescopic triangular plate 413 is located at the front end of the limit spring 412 and is fixedly connected to each other, and is used to support the separated battery cells;

[0079] The fitting block 414 is located below the sliding telescopic rod 411 and is fixedly connected to each other, and is used to be nested with the limiting groove 362 to achieve the purpose of mutual linkage.

[0080] Working principle of the present invention:

[0081] First, when a new battery stack needs to be placed, the fitting block 414 and the limiting groove 362 are fitted and fixed (eg, Figure 15As shown in the figure, the limiting sliding plate 34 is pulled out of the chute portion 33 and a new battery cell stack is put in. The sliding plate 34 is then pushed to drive the battery cell stack to enter above the bottom plate 32. During the process of the battery cell entering, the limiting sliding plate 34 is pushed to move toward the rear end face of the chute portion 33. During the movement, the battery cell stack squeezes and pushes the limiting vertical plate 36 to move along the track chute 311 inside the extension groove 35. During the movement, the moving main body plate 361 drives the fitting block 414 fixed to the limiting groove 362 to move. The fitting block 414 then drives the sliding telescopic rod 411 to move back and forth along the chute and to extend and retract left and right, driving the telescopic triangular plate 413 to always be in the same vertical plane with the outer wall of the battery cell, away from the two sides of the rotating fixing rod 22. The separation device 41 synchronizes the telescopic length of the other two separation devices 41 by connecting the fixing rods 43. When the distance between the two sets of limiting vertical plates 36 is consistent with the size of the battery cells, the battery cell stack no longer squeezes the edge of the limiting vertical plates 36, but squeezes the squeezing plate 313 located on the inner side of the limiting vertical plates 36. At the same time, due to the squeezing of the sliding base 310 by the limiting spring 1 38, the limiting vertical plates 36 are fixed, thereby squeezing the squeezing plate 313, causing the squeezing plate 313 to move backward. The backward squeezing plate 313 squeezes the limiting spring 2 314, causing the limiting spring 2 314 to relax its support on one end of the connecting rope 312, causing the connecting rope 312 to move backward. Then the limiting spring 317 drives the fixing column 318 into the fixing hole 315 , completing the sliding base 310, thereby achieving the fixation of the battery cell stack, and then the rotating fixing rod 22 is rotated from the vertical state to the horizontal state. During the rotation of the rotating fixing rod 22, the restricted rod 224 is driven by the sliding part 223 to rotate, and is squeezed by the extrusion rail 226, causing the restricted rod 224 to move downward, and then the lower end of the restricted rod 224 enters the limiting hole 225, completing the self-locking and one end of the rotating fixing rod 22 enters the fixing groove 23. Since the rotating rotating fixing rod 22 completes the self-locking, the self-locking rotating fixing rod 22 achieves the fixation of the limiting sliding plate 34 in the horizontal direction, and then drives the hydraulic telescopic rod 37 to lift the slide groove part 33, and then the slide groove part 33 drives the limiting sliding plate 34 and the battery cell to be lifted to the maximum At this time, the uppermost battery cell exceeds the highest point of the limiting vertical plate 36, and the tip of the telescopic triangle 413 and the separation line 44 are flush with the bottom of the uppermost battery cell, and then the separation line 44 is driven horizontally by the electric telescopic rod 42 to the bottom of the uppermost battery cell. Because the separation line 44 has a certain thickness, a gap is generated between the two adjacent battery cells at the upper end, and then the tip of the telescopic triangle 413 is extended to between the two adjacent battery cells by the elastic action of the limit spring four 412, and the telescopic triangle 413 supports the uppermost battery cell, and then the robot arm is used to absorb and grab the uppermost battery cell, realizing the loading of a single battery cell, and then the separation line 44 is restored to its original state and the above process is repeated.Lift the top battery cell to separate it.
