Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rotary conveying technology, and in particular relates to a rotary conveying mechanism. Background Technology
[0002] After solar cells are manufactured, they are graded according to their photoelectric conversion efficiency to maximize profitability. The testing of solar cell photoelectric conversion efficiency is known in the industry as IV testing. To improve solar cell production efficiency, many automated IV testing devices for solar cells have emerged on the market. These automated testing devices typically use rotary conveyor mechanisms to rotate and transport the solar cells to various testing stations.
[0003] In the prior art, Chinese Patent Publication No. CN119176375B discloses a high-precision IV testing device and method for solar cells. The high-precision IV testing device for solar cells includes a rotating unit, which comprises a rotating support plate for rotating motion and an adsorption fixture equidistantly positioned on the rotating support plate. The adsorption fixture includes a support frame extending beyond the rotating support plate and adsorption support rods for adsorbing and supporting solar cells. The adsorption support rods are equipped with several suction nozzles. In this design, the support frame has a rectangular structure and forms a hollow working area around it. The adsorption support rods are positioned within the working area. There are two sets, each adsorbing and supporting two battery halves. When the two battery halves are placed on the adsorption support rod, the whole structure is within the working area. However, one of the battery halves is far from the rotation center, and the connection between the support frame and the rotating support plate is relatively narrow, resulting in low connection reliability. Due to the gravity of the support frame itself, the part of the support frame away from the rotation center will tend to sag, resulting in low stability. This causes the battery half away from the rotation center to sag downwards. Since the pins on the battery half are very small, when the battery half sags, the test probe cannot accurately contact the pins, which will affect the test accuracy and reduce the test yield.
[0004] Therefore, it is necessary to provide a rotary conveying mechanism to solve the above-mentioned technical problems. Utility Model Content
[0005] The main purpose of this utility model is to provide a rotary conveying mechanism that can ensure the stability of rotary conveying, improve the testing accuracy of products, and thus improve the product testing yield.
[0006] This utility model achieves the above-mentioned objective through the following technical solution: a rotary conveying mechanism, comprising a rotary drive component, a support plate driven by the rotary drive component to rotate, and an adsorption fixture disposed on the support plate for adsorbing and supporting battery cells. The adsorption fixture includes a support component fixed on one side of the support plate and extending beyond the support plate, and a plurality of adsorption support rods disposed on the support component. The support component includes a first support part, a second support part, and a third support part connected in sequence. A first mounting part is formed at the connection between the first support part and the second support part to assemble with the support plate. The width of both the second support part and the first mounting part is widened.
[0007] Furthermore, the first support part, the second support part, and the third support part are connected in sequence to form a "U" shape and surround to form a hollow working area, and the adsorption support rod is disposed in the working area.
[0008] Furthermore, the first support portion and the third support portion are arranged parallel to each other, and the adsorption support rod is connected to the inner side of both the first support portion and the third support portion, with the other end of the adsorption support rod extending outward toward the working area.
[0009] Furthermore, two adsorption support rods are provided on the inner side of both the first support portion and the third support portion.
[0010] Furthermore, the adsorption support rod is provided with a plurality of suction nozzles spaced apart along its length.
[0011] Furthermore, the adsorption support rod includes an adsorption support portion for adsorbing and supporting the battery cell, and a second mounting portion for mounting with the first support portion and the third support portion.
[0012] Furthermore, the second mounting part is provided with a waist-shaped hole, and the first support part and the third support part are provided with mounting holes that mate with the waist-shaped hole. A first fastener is screwed into the waist-shaped hole and the mounting hole to facilitate the installation of the adsorption support rod on the first support part or the third support part.
[0013] Furthermore, the supporting component and the adsorption support rod are provided with interconnected air passages.
[0014] Furthermore, it also includes a pneumatic slip ring rotatably connected to the support plate, with one end of the air passage connected to the suction nozzle and the other end connected to the air nozzle on the pneumatic slip ring.
[0015] Furthermore, the adsorption fixture is detachably mounted on the support plate by a second fastener.
[0016] Compared with the prior art, the beneficial effects of the rotary conveying mechanism of this utility model are as follows:
[0017] (1) The support component includes three interconnected support parts that extend beyond the support plate. Compared with the four-sided support of the rectangular support frame in the prior art, one side support is reduced, thereby reducing the weight of the support component. Moreover, the reduced support side is far away from the rotation center, which further reduces the tendency of the adsorption fixture to sag, ensures the stability of the adsorption fixture, and thus ensures the stability of the rotational conveying, which can prevent the product from sag, improve the product testing accuracy, and thus improve the product testing yield.
[0018] (2) A first mounting part is formed at the connection between the first support part and the second support part to be assembled with the support plate. The width of the second support part and the first mounting part are both widened, which improves the stability of the first mounting part and the support plate and also improves the stability of the adsorption fixture itself. It can avoid the tendency of the adsorption fixture to sag, thereby avoiding product sag, improving the test accuracy of the product, and thus improving the test yield of the product.
[0019] (3) The first support part and the third support part are arranged in parallel to each other. The adsorption support rod is set on the first support part and the third support part, which can make the two battery cells as close as possible to the first mounting part, and then closer to the rotation center, which improves the stability of the adsorption fixture and further reduces the tendency of the adsorption fixture to sag, thereby avoiding product sag, improving the product testing accuracy, and thus improving the product testing yield.
[0020] (4) The second mounting part of the adsorption support rod is provided with a waist-shaped hole to facilitate the adjustment of the position of the adsorption support rod. The first support part and the third support part are provided with scales at the installation positions of the second mounting part. Correspondingly, the second mounting part is provided with a scribbling line. When the position of the adsorption support rod is adjusted, the adjustment size can be displayed in real time through the scale, which reduces the difficulty of position adjustment and reduces the time of position adjustment.

[0027] Please refer to Figures 1-2 This embodiment is a rotary conveying mechanism 100, which includes a rotary drive 1, a support plate 2 driven by the rotary drive 1 to rotate, and an adsorption fixture 3 detachably mounted on the support plate 2 for adsorbing and supporting battery cells. The adsorption fixture 3 is detachably mounted on the support plate 2 by a second fastener (not shown in the figure), which facilitates replacement and repair if the adsorption fixture 3 is damaged.
[0028] The adsorption fixture 3 includes a support member 31 that is fixed on one side of the support plate 2 and extends out of the support plate 2, and a plurality of adsorption support rods 32 provided on the support member 31 for adsorbing and supporting the battery cell 200.
[0029] The support component 31 has a "U"-shaped structure, comprising three interconnected support portions extending beyond the support plate 2: a first support portion 311, a second support portion 312, and a third support portion 313, connected sequentially. The support component 31 has three-sided support, which, compared to the rectangular support frame with four-sided support disclosed in the high-precision battery cell IV testing equipment and method disclosed in Chinese Patent Publication No. CN 119176375B, reduces one side of the support, thus lightening the weight of the support component 31. Furthermore, the reduced support side is farther from the rotation center, further reducing the tendency of the adsorption fixture 3 to sag, ensuring the stability of the adsorption fixture 3, thereby preventing battery cell sagging, improving the testing accuracy of the battery cells, and ultimately increasing the testing yield of the battery cells.
[0030] A first mounting portion 314 is formed at the connection between the first support portion 311 and the second support portion 312 to be assembled with the support plate 2. The width of both the second support portion 312 and the first mounting portion 314 has been widened, which improves the stability of the first mounting portion 314 and the support plate 2 and also improves the stability of the adsorption fixture 3 itself. This can prevent the adsorption fixture 3 from sagging, thereby preventing the battery cells from sagging, improving the testing accuracy of the battery cells, and thus improving the testing yield of the battery cells.
[0031] The first support part 311, the second support part 312 and the third support part 313 are connected in sequence to form a "U" shape and surround to form a hollow working area 34. The adsorption support rod 32 is set in the working area 34, and a number of suction nozzles 33 are spaced apart on the adsorption support rod 32 along its length extension direction.
[0032] The first support part 311 and the third support part 313 are arranged parallel to each other, and a plurality of adsorption support rods 32 are provided on the inner side of the first support part 311 and the third support part 313. One end of the adsorption support rod 32 is provided on the first support part 311 or the third support part 313, and the other end extends outward toward the working area 34.
[0033] In this embodiment, two adsorption support rods 32 are provided on one side of both the first support portion 311 and the third support portion 313. The two adsorption support rods 32 are arranged in parallel. The two adsorption support rods 32 on the first support portion 311 and the two adsorption support rods 32 on the third support portion 313 respectively adsorb and support one battery cell. When the two battery cells are placed on the adsorption support rods 32, the whole assembly is located within the working area 34, and there is a certain distance between adjacent battery cells. By setting the adsorption support rods 32 on the first support portion 311 and the third support portion 313, the two battery cells can be brought as close as possible to the first mounting portion 314, and thus closer to the rotation center. This further reduces the tendency of the adsorption fixture 3 to sag, thereby preventing the battery cells from sagging, improving the testing accuracy of the battery cells, and thus improving the testing yield of the battery cells.
[0034] In other embodiments, the adsorption support rods 32 may also be configured to correspond to only one battery cell, arranged around the outline of the entire battery cell. For example, two sets may be provided to support the opposite side edges of the entire battery cell, or four sets may be provided to support the flattened perimeter of the battery cell, or multiple sets may be provided to support the bottom area of the entire battery cell. The number of adsorption support rods 32 is not limited here.
[0035] The adsorption support rod 32 includes an adsorption support part 321 for adsorbing and supporting the battery cell and a second mounting part 322 for mounting with the first support part 311 and the third support part 313. The second mounting part 322 is provided with an oblong hole 323 to facilitate the adjustment of the position of the adsorption support rod 32. The first support part 311 and the third support part 313 are provided with scales at the positions where they are mounted with the second mounting part 322. Correspondingly, the second mounting part 322 is provided with a scribing line. When the position of the adsorption support rod 32 is adjusted, the size of the position adjustment can be displayed in real time through the scale, which reduces the difficulty of position adjustment and reduces the time of position adjustment.
[0036] The first support portion 311 and the third support portion 313 are provided with mounting holes that mate with the oblong hole 323. A first fastener (not shown in the figure) is screwed into the oblong hole 323 and the mounting hole to facilitate the installation of the adsorption support rod 32 on the first support portion 311 or the third support portion 313. The adsorption support rod 32 is detachably installed on the first support portion 311 and the third support portion 313 by means of the first fastener, so that if the adsorption support rod 32 is damaged, it is easy to replace and repair.
[0037] The first and second fasteners can be selected from one of the following: bolts, pins, or screws, or other fasteners, without limitation.
[0038] Since the rotary conveying mechanism 100 rotates frequently in one direction, and the adsorption support rod 32 needs to be ventilated, in order to facilitate the connection of the air pipe and prevent the air pipe from getting tangled, the rotary conveying mechanism 100 also includes a pneumatic slip ring (not shown in the figure) that is rotatably connected to the support plate 2. The support component 31 and the adsorption support rod 32 are provided with interconnected air passages (not shown in the figure). One end of the air passage is connected to the suction nozzle 33 and the other end is connected to the air nozzle on the pneumatic slip ring (not shown in the figure).
[0039] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
