[0029] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.
[0030] like Figures 1 to 7 As shown, the screen printing equipment provided by this utility model includes a feeding device 100, a loading and conveying device 200, a printing device 300, a unloading device 400, and an unloading and conveying device 500.
[0031] The feeding device 100 is used to transport the battery cells to be printed; the printing device 300 is located downstream of the feeding device 100 and is used to perform screen printing operations; the loading and conveying device 200 is used to transport the battery cells to be printed on the feeding device 100 to the printing device 300; the unloading device 400 is located downstream of the printing device 300 and is used to transport the printed battery cells; the unloading and conveying device 500 is used to transport the printed battery cells on the printing device 300 to the unloading device 400.
[0032] The feeding and conveying device 200 includes a second guide rail 202 extending along the cell conveying direction and a feeding and conveying body 201 slidably mounted on the second guide rail 202. The feeding and conveying body 201 reciprocates along the second guide rail 202 between the feeding device 100 and the printing device 300, thereby conveying the cell to be printed from the feeding device 100 to the printing device 300.
[0033] The loading and conveying device 200 further includes a first driving member 203 that drives the loading and conveying body 201 and the second guide rail 202 to move along the height direction. The loading and conveying body 201 moves upward to move the battery cells off the feeding device 100, and moves downward to place the battery cells on the printing device 300.
[0034] The printing apparatus 300 includes a first guide rail 301, a printing stage 302 slidably mounted on the first guide rail 301, and a printing head 303 located above the printing stage 302.
[0035] The feeding and conveying body 201 transports the battery cells to be printed on the feeding device 100 to the printing stage 302. Then, the printing stage 302 moves along the first guide rail 301 to directly below the printing head 303, and then the printing head 303 performs screen printing on the battery cells on the printing stage 302.
[0036] The feeding device 100 is located between the first guide rail 301 and the second guide rail 202, which reduces the distance the feeding and conveying body 201 moves along the height direction during the transport of battery cells, thereby improving transport efficiency. The feeding device 100 can use a conveyor belt to transport the battery cells.
[0037] It should be noted that the extension direction of the second guide rail 202 is the same as that of the first guide rail 301. The second guide rail 202 is located above the first guide rail 301, and the two partially overlap. This overlap means that the end of the second guide rail 202 away from the feeding device 100 extends beyond the end of the first guide rail 301 near the feeding device 100. This reduces the overall length of the screen printing equipment, making its structure more compact.
[0038] After the battery cells on the printing platform 302 are printed, the printing platform 302 continues to move along the first guide rail 301 to the side where the unloading device 400 is located. The unloading and conveying device 500 is used to transport the printed battery cells on the printing platform 302 to the unloading device 400.
[0039] The structure of the unloading and conveying device 500 is the same as that of the loading and conveying device 200. The unloading and conveying device 500 includes a third guide rail 502 and an unloading and conveying body 501 slidably mounted on the third guide rail 502. The unloading and conveying body 501 moves reciprocally along the third guide rail 502 between the printing stage 302 and the unloading device 400, thereby conveying the printed battery cells from the printing stage 302 to the unloading device 400.
[0040] The unloading and conveying device 500 further includes a second driving member 503 that drives the unloading and conveying body 501 and the third guide rail 502 to move along the height direction. The unloading and conveying body 501 moves upward to move the battery cell off the printing stage 302, and the unloading and conveying body 501 moves downward to place the battery cell on the unloading device 400.
[0041] The unloading device 400 is located between the first guide rail 301 and the third guide rail 502. This reduces the distance the unloading and conveying body 501 moves along the height direction during the transport of the battery cells, thus improving transport efficiency. The unloading device 400 can use a conveyor belt to transport the battery cells. Preferably, the unloading device 400 and the feeding device 100 are located at the same height.
[0042] Similarly, the third guide rail 502 extends in the same direction as the first guide rail 301, and the third guide rail 502 is located above the first guide rail 301, with the two partially overlapping. This overlap means that the end of the second guide rail 202 furthest from the feeding device 400 extends beyond the end of the first guide rail 301 closest to the feeding device 400. This reduces the overall length of the screen printing equipment, making its structure more compact.
[0043] In some embodiments, the first guide rail 301 has redundant sections 301a at both ends along its extension direction, and the redundant sections 301a partially overlap with the feeding device 100 or the unloading device 400. The redundant sections 301a need to be reserved for the first guide rail 301 for subsequent installation, debugging, and maintenance, and also to adaptively adjust the travel of the printing stage 302.
[0044] By partially aligning the redundant segments 301a at both ends with the feeding device 100 and the unloading device 400, the length of the entire screen printing equipment can be further reduced, making the structure of the entire screen printing equipment more compact. On the other hand, the distance that the feeding and unloading conveying body 201 and the unloading and conveying body 501 move along their respective guide rails during the conveying process can be reduced, thereby improving the conveying efficiency.
[0045] The first guide rail 301 also includes a first surface 301b and a second surface 301c disposed opposite to each other, and the printing stage 302 is slidably mounted on both the first surface 301b and the second surface 301c. The two printing stages 302 can reciprocate independently along the first guide rail 301. When one printing stage 302 moves from the feeding end to the unloading end, the other printing stage 302 moves from the unloading end to the feeding end, thereby improving the efficiency of screen printing of battery cells.
[0046] To prevent the printing stages 302 on both sides from interfering with each other during movement along the first guide rail 301, each printing stage 302 has a lifting drive 302a connected to the first guide rail 301 and driving the printing stage 302 to move in the height direction. When the printing stage 302 on the first side 301b and the printing stage 302 on the second side 301c intersect, one of the printing stages 302 can be raised so that the two printing stages 302 are staggered in the height direction. In this way, the two printing stages 302 can stagger when they intersect and continue to move in their respective directions of movement.
[0047] It should be specifically noted that the screen printing equipment described in this application is applied to screen printing half-cell batteries. To reduce the number of printing heads 303 and improve the screen printing efficiency of half-cell batteries, each printing head 303 is provided with two printing zones spaced apart, enabling the simultaneous printing of two half-cell batteries. Correspondingly, the printing stage 302 can simultaneously hold two half-cell batteries, and the printing stage 302 is provided with two independent adsorption zones spaced apart for holding the half-cell batteries.
[0048] The distance between the two printing areas is 30-40mm. If the distance is too small, the two printing areas may affect each other when printing two half-cell batteries, resulting in poor printing effect. If the distance is too large, it will increase the volume of the printing head 303.
[0049] In addition, to reduce the spacing between the two half-cells of a solar cell, allowing them to share a single printing head 303, the feeding device 100 replaces the traditional two-line feeding with a single-line feeding. Furthermore, when feeding the half-cell to be printed, the feeding device 100 ensures that the width direction of the half-cell is aligned with the transmission direction. This reduces the spacing between the two half-cells while preventing the printing head 303 from becoming excessively long and narrow, which could negatively impact the printing and structural stability of the printing head 302.
[0050] When both the first surface 301b and the second surface 301c of the first guide rail 301 are provided with the printing platform 302, in order to improve the handling efficiency of the feeding and handling device 200, the number of battery cells handled by the feeding and handling device 200 at one time is the same as the number of printing platforms 302.
[0051] It is understood that two half-cell batteries are placed on each of the printing stages 302. The printing stages 302 on the first side 301b and the second side 301c are alternately moved to the feeding end to receive the battery cells transported by the feeding and conveying device 200. The feeding and conveying device 200 can transport the half-cell battery cells to the printing stage 302 located at the feeding end in one transport.
[0052] Similarly, in order to improve the handling efficiency of the unloading and handling device 500, the number of battery cells handled by the unloading and handling device 500 at one time is the same as the number of printing platforms 302.
[0053] In one specific embodiment, the first surface 301b and the second surface 301c of the first guide rail 301 are each provided with two printing platforms 302. The feeding and conveying device 200 carries four half-cell batteries at a time and places them on the two printing platforms 302 respectively.
[0054] In summary, by placing the second guide rail 202 of the feeding and conveying device 200 above the first guide rail 301 of the printing device 300, and making the second guide rail 202 and the first guide rail 301 partially overlap, the present invention can reduce the overall length of the screen printing equipment and make the structure of the screen printing equipment more compact.
[0055] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
[0056] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
