[0034] Please refer to Figures 1 to 5 In the first aspect, the embodiment of the present invention provides an equal spacing expansion device 100 for small-size cells for flexible solar cells, which is used to expand the cell 200. It can realize the automatic equal spacing expansion of multiple cells 200, has a high degree of mechanization, ensures that multiple cells 200 are arranged neatly with equal spacing, saves time and labor, reduces time and labor costs, has high arrangement efficiency, good arrangement effect, and is suitable for mass production.

[0035] It should be noted that in the production process of flexible solar cells, hundreds of small-sized cells 200 need to be bonded to a flexible circuit board, with equal gaps between adjacent cells 200 to form a flexible solar cell. In this way, when the flexible solar cell needs to be used, the flexible circuit board is unfolded to achieve the flattening of multiple cells 200 to increase the contact area between the cells 200 and the sun, thereby achieving the photovoltaic power generation function of the flexible solar cell and ensuring power generation efficiency; when the flexible solar cell is not needed, the flexible circuit board is rolled up for easy storage and saves space. In this process, since there is a certain gap between adjacent cells 200, the cells 200 will not interfere with the rolling of the flexible circuit board, which is convenient for the storage of the flexible solar cell.

[0036] In this embodiment, the battery cell 200 is arranged in a rectangular shape, and the size of the battery cell 200 is 50mm*30mm. It is obviously inappropriate to manually arrange the small pieces of such size and quantity (it is time-consuming and labor-intensive, with high time and labor costs, not suitable for mass production, and it is easy for the spacing between adjacent battery cells 200 to be different, affecting the quality of the flexible solar cell). Therefore, the multiple battery cells 200 are first laid out neatly and close to each other, and then the equal spacing expansion device 100 for small-size battery cells for flexible solar cells of the present invention is used to expand the multiple battery cells 200. However, it is not limited to this. In other embodiments, the size of the battery cell 200 may be 40mm*40mm, or 30mm*30mm, and the size of the battery cell 200 is not specifically limited.

[0037] The uniform spacing extension device 100 for small-sized cells for flexible solar cells comprises a frame 110, a carrier 120, a lifting mechanism 130 and an extension mechanism 140. The carrier 120 and the lifting mechanism 130 are both mounted on the frame 110, the carrier 120 is used to carry a plurality of cells 200 that are neatly laid and close to each other, the lifting mechanism 130 is connected to the extension mechanism 140, the extension mechanism 140 is arranged above the carrier 120 at intervals, the lifting mechanism 130 is used to drive the extension mechanism 140 to descend or ascend, and the extension mechanism 140 is used to suck up a plurality of cells 200 and perform uniform spacing extension on them.

[0038] The distance expansion mechanism 140 includes a mounting seat 141, a first driving member 142, a camshaft 143 and a plurality of slides 144. The lifting mechanism 130 is connected to the mounting seat 141, and the mounting seat 141 is arranged above the support platform 120. The lifting mechanism 130 is used to drive the mounting seat 141 to rise or fall so that the mounting seat 141 is away from or close to the support platform 120. The plurality of slides 144 are arranged side by side along the first direction, and all slide with the mounting seat 141 in the first direction. Two adjacent slides 144 are arranged in close contact, that is, the slide 144 can slide relative to the mounting seat 141 along the first direction, and the mounting seat 141 can limit and guide the slide 144. The first driving member 142 is installed on the mounting seat 141 and connected to the camshaft 143. The axial direction of the camshaft 143 is the same as the first direction. The first driving member 142 is used to drive the camshaft 143 to rotate.

[0039] Furthermore, the circumference of the camshaft 143 is provided with a plurality of spiral grooves 1431, which are arranged in sequence and at intervals in the axial direction of the camshaft 143, and have different spiral angles. A matching rod 1441 is provided on one side of the slide 144, and a first suction cup 1442 is provided on the other side. Each matching rod 1441 is slidably matched with a spiral groove 1431, and the matching rod 1441 can slide relative to the spiral groove 1431, and the spiral groove 1431 can guide and limit the matching rod 1441, and each first suction cup 1442 is used to absorb a group of battery cells 200. Specifically, the lifting mechanism 130 is used to drive the slide 144 to descend through the mounting seat 141 so that each first suction cup 1442 vacuum absorbs a group of battery cells 200. The first driving member 142 is used to drive the camshaft 143 to rotate, so as to drive the slide 144 to slide along the first direction through the side wall of the spiral groove 1431. Since the spiral angles of the multiple spiral grooves 1431 are different, when the camshaft 143 rotates the same angle, the sliding distances of the multiple slides 144 corresponding to the multiple spiral grooves 1431 in the first direction are different. By setting different spiral angles of the multiple spiral grooves 1431, the multiple slides 144 can be separated at equal intervals, so that multiple groups of battery cells 200 can be separated at equal intervals, and the automated equal-interval expansion of multiple battery cells 200 is realized. The degree of mechanization is high, which ensures that the multiple battery cells 200 are arranged neatly at equal intervals, saves time and effort, reduces time cost and labor cost, has high arrangement efficiency, good arrangement effect, and is suitable for mass production.

[0040] Preferably, the plurality of spiral grooves 1431 include a first spiral groove 1432 and a plurality of second spiral grooves 1433. The plurality of second spiral grooves 1433 are all arranged on one side of the first spiral groove 1432, the spiral angle of the first spiral groove 1432 is 0, and the spiral angles of the plurality of second spiral grooves 1433 increase in sequence in the direction away from the first spiral groove 1432. That is, in the process of the first driving member 142 driving the camshaft 143 to rotate, the matching rod 1441 and its corresponding slide 144 that are slidably matched with the first spiral groove 1432 will not move, the matching rod 1441 and its corresponding slide 144 that are slidably matched with the first second spiral groove 1433 (a second spiral groove 1433 closest to the first spiral groove 1432) have the smallest sliding distance in the first direction, and the matching rod 1441 and its corresponding slide 144 that are slidably matched with the last second spiral groove 1433 (a second spiral groove 1433 farthest from the first spiral groove 1432) have the largest sliding distance in the first direction. Specifically, the sliding distance in the first direction of the mating rod 1441 and its corresponding slide 144 that slide with the first second spiral groove 1433 is represented as the first sliding distance, and the sliding distance in the first direction of the mating rod 1441 and its corresponding slide 144 that slide with the last second spiral groove 1433 is represented as the second sliding distance. The second sliding distance is equal to the first sliding distance multiplied by the number of second spiral grooves 1433, so as to ensure that the multiple slides 144 corresponding to the multiple second spiral grooves 1433 are separated at equal intervals during the process of the first driving member 142 driving the camshaft 143 to rotate.

[0041] The plurality of spiral grooves 1431 further include a plurality of third spiral grooves 1434. The plurality of third spiral grooves 1434 are all disposed on the other side of the first spiral groove 1432, that is, the third spiral groove 1434 and the second spiral groove 1433 are disposed on both sides of the first spiral groove 1432. The rotation direction of the third spiral groove 1434 is opposite to that of the second spiral groove 1433, and the spiral angles of the plurality of third spiral grooves 1434 increase sequentially in the direction away from the first spiral groove 1432. That is, in the process of the first driving member 142 driving the camshaft 143 to rotate, the mating rod 1441 and its corresponding slide 144 that slide with the first spiral groove 1432 will not move, the mating rod 1441 and its corresponding slide 144 that slide with the first third spiral groove 1434 (a third spiral groove 1434 closest to the first spiral groove 1432) have a smallest sliding distance in the opposite direction of the first direction, and the mating rod 1441 and its corresponding slide 144 that slide with the last third spiral groove 1434 (a third spiral groove 1434 farthest from the first spiral groove 1432) have a largest sliding distance in the opposite direction of the first direction. Specifically, the sliding distance of the mating rod 1441 and its corresponding slide 144 that slide with the first third spiral groove 1434 in the opposite direction of the first direction is represented as the third sliding distance, and the sliding distance of the mating rod 1441 and its corresponding slide 144 that slide with the last third spiral groove 1434 in the opposite direction of the first direction is represented as the fourth sliding distance. The fourth sliding distance is equal to the third sliding distance multiplied by the number of third spiral grooves 1434, so as to ensure that the multiple slides 144 corresponding to the multiple third spiral grooves 1434 are separated at equal intervals during the process of the first driving member 142 driving the camshaft 143 to rotate.

[0042] By setting a plurality of second spiral grooves 1433 on one side of the first spiral groove 1432 and a plurality of third spiral grooves 1434 on the other side, when the first driving member 142 drives the camshaft 143 to rotate, the slide 144 corresponding to the first spiral groove 1432 remains stationary, the plurality of slides 144 corresponding one-to-one to the plurality of second spiral grooves 1433 slide along the first direction, and the plurality of slides 144 corresponding one-to-one to the plurality of third spiral grooves 1434 slide in the opposite direction of the first direction, thereby achieving equal spacing separation of all the slides 144, with high separation efficiency and high separation accuracy.

[0043] Furthermore, the projections of the multiple spiral grooves 1431 on the cross section of the camshaft 143 are all arc-shaped, and have the same shape, size and position, that is, the arcs of the multiple spiral grooves 1431 on the cross section of the camshaft 143 have the same central angle, the same radius, the same two end positions, and the two extreme sliding positions of the multiple mating rods 1441 in the multiple spiral grooves 1431 are the same. Specifically, the spiral groove 1431 is relatively provided with a starting end and an end end; when multiple slides 144 are arranged side by side along the first direction and close to each other, the matching rod 1441 of each slide 144 is arranged at the starting end of a spiral groove 1431; thereafter, the first driving member 142 drives the camshaft 143 to rotate, and the matching rod 1441 moves in the spiral groove 1431 toward a position close to the end, so that the multiple slides 144 are separated at equal intervals. In this process, the rotation angle of the camshaft 143 is adjusted to control the separation distance of two adjacent slides 144, thereby controlling the separation distance of two adjacent groups of battery cells 200; when the camshaft 143 rotates to the extreme position, the matching rod 1441 of each slide 144 is arranged at the end of a spiral groove 1431, at which time the separation distance of two adjacent slides 144 reaches the maximum, and the matching rod 1441 limits the camshaft 143 through the end wall of the spiral groove 1431 to prevent the camshaft 143 from continuing to rotate.

[0044] In this embodiment, the center angle of the arc formed by the projection of the spiral groove 1431 on the cross section of the camshaft 143 is 240 degrees, that is, the maximum rotation angle of the camshaft 143 is 240 degrees. However, this is not limited to this. In other embodiments, the center angle of the arc formed by the projection of the spiral groove 1431 on the cross section of the camshaft 143 can be 200 degrees or 280 degrees, and the size of the center angle of the arc formed by the projection of the spiral groove 1431 on the cross section of the camshaft 143 is not specifically limited.

[0045] Preferably, the mounting seat 141 is provided with a slide rail 1411, and the slide platform 144 is provided with a slider 1443. The slider 1443 is slidably matched with the slide rail 1411. The slide rail 1411 is extended along the first direction. The slider 1443 can slide relative to the slide rail 1411. The slide rail 1411 can guide and limit the slider 1443 to ensure that the slider 1443 can only slide along the first direction.

[0046] Preferably, a cylindrical head 1444 is provided at the free end of the mating rod 1441, and the cylindrical head 1444 can be slidably disposed between the two side walls of the spiral groove 1431. The axial direction of the cylindrical head 1444 is perpendicular to the axial direction of the camshaft 143. Through the cooperation between the circumferential surface of the cylindrical head 1444 and the two side walls of the spiral groove 1431, the friction force of the mating rod 1441 sliding relative to the spiral groove 1431 can be effectively reduced, thereby ensuring the stability of the mating rod 1441 during the sliding process.

[0047] It should be noted that the first suction cup 1442 is provided with a plurality of suction holes 1445, and the plurality of suction holes 1445 are sequentially spaced along the second direction, and each suction hole 1445 is used to absorb a battery cell 200, and the second direction is perpendicular to the first direction, that is, after the equal spacing expansion device 100 for small-size battery cells of a flexible solar cell expands the plurality of battery cells 200, the plurality of battery cells 200 are equally spaced and separated in the first direction, and the positions of the plurality of battery cells 200 in the second direction remain unchanged (or are still in a state of being close to each other). Specifically, the area of ​​the suction hole 1445 is smaller than the area of ​​the battery cell 200, so as to ensure that the plurality of suction holes 1445 arranged at intervals can absorb the plurality of battery cells 200 arranged close to each other one by one.

[0048] Preferably, the equi-pitch expansion device 100 for small-size cells for flexible solar cells further includes a vacuum pump 150. The vacuum pump 150 includes a vacuum pump (not shown) and a plurality of branch pipes (not shown), the vacuum pump is connected to the plurality of branch pipes at the same time, each branch pipe is connected to a suction hole 1445, so as to realize the vacuum adsorption function of each suction hole 1445 and ensure the vacuum adsorption effect.

[0049] The vacuum pumping mechanism 150 further includes a main pipeline 151, a vacuum gas distribution block 152, a plurality of branch pipelines (not shown) and a bus 153. The vacuum pump is connected to the vacuum gas distribution block 152 through the main pipeline 151, the vacuum gas distribution block 152 is connected to the bus 153 through a plurality of branch pipelines, the bus 153 is connected to a plurality of suction holes 1445 of the first suction cup 1442 through a plurality of branch pipelines, the vacuum gas distribution block 152 is used to realize the primary gas distribution function, and the bus 153 is used to realize the secondary gas distribution function. Specifically, through the two-stage gas distribution of the vacuum gas distribution block 152 and the bus 153, the thicker main pipeline 151 is divided step by step into multiple thinner branch pipelines, and connected with multiple suction holes 1445, thereby avoiding the situation where the vacuum pump directly leads to multiple vacuum pipelines to connect multiple suction holes 1445, thereby avoiding the problem of uneven air flow in multiple vacuum pipelines caused by large changes in pipeline diameter, and thus realizing the step-by-step transition function, ensuring the pressure balance of multiple pipelines at the same level (multiple branch pipelines or multiple branch pipelines), so that the entire vacuum system is stable and reliable.

[0050] The lifting mechanism 130 includes a support frame 131, a second driving member 132 and a lifting frame 133.
