Specific embodiments

[0040] In order to make the personnel in the technical field better understand the utility model scheme, the utility model is further explained in detail below in combination with the drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0041] The core of this utility model is to provide a battery cell production apparatus, the structural schematic diagram of one specific embodiment of which is shown below. Figure 1 As shown, this is referred to as Specific Implementation Method 1, which includes a transmission component 10, an edge fixing component 40, a first mounting component, a second mounting component, and a water-laying component 30;

[0042] The water-laying component 30 includes a hanging rod 31; both ends of the hanging rod 31 include protruding ends 31A.

[0043] The edge fastener 40 includes a main body 41 and an extension 42;

[0044] The main body 41 of the kit is provided with a receiving space 41A for receiving the protruding end 31A; the protruding end 31A is suspended from the edge fixing member 40 by the first mounting member;

[0045] The extension 42 includes a mounting hole 42A, through which the second mounting member passes to detachably mount the edge fixing member 40;

[0046] The first mounting member is used to adjust the height of the protruding end 31A in the receiving space 41A, and / or the second mounting member is used to adjust the position of the edge fixing member 40 in a plane perpendicular to the height direction (i.e., the horizontal direction).

[0047] In actual production, before spreading water on the battery cell 01 to be treated, water must first be sprayed on the battery cell 01 to be treated. Spraying water requires the use of a spray assembly 20. The spray assembly 20 corresponds to the battery cell 01 to be treated. It can be considered that each battery cell 01 to be treated is treated by a group consisting of the spray assembly 20 and the water spreading component 30.

[0048] Because the adhesion between the water film 02 formed on the battery cell 01 to be treated after water spraying is very weak, the upper surface of the battery cell 01 to be treated must be kept horizontal throughout the entire process of setting the water film 02 and subsequent acid etching to prevent the water film 02 from slipping off. Therefore, the bearing surface of the transmission component 10 in this utility model needs to be kept horizontal. In this utility model, "above" refers to the vertical direction above, and "below" refers to the vertical direction below. "Above" and "below" together constitute the "height direction" in this utility model. Taking the N-type TOPCon battery as an example, the front side of the battery cell with PSG grown is the lower surface, and the back side of the battery cell is the upper surface. Figure 2 This is a top view of the battery cell production apparatus. Figure 3 This is a side view of the solar cell production apparatus. Additionally, see reference... Figure 4 , Figure 4A schematic view of the structure of the water film 02 being laid by the water laying member 30 on the surface of the battery piece 01 to be processed.

[0049] As a preferred embodiment, the transmission assembly 10 is a transmission channel composed of multiple rollers arranged in the transmission direction. The transmission channel composed of the rollers has high flexibility in arrangement, so that the transmission assembly 10 can not only extend linearly, but also can be arbitrarily diverted. In addition, the transmission channel composed of the rollers can expose the lower surface of the battery piece 01 to be processed, and can be directly applied in a subsequent acid etching tank, thereby simplifying the structure of the subsequent device.

[0050] Further, the water laying member 30 is spaced apart from the upper surface of the battery piece 01 to be processed by a first distance;

[0051] The first distance ranges from 2 mm to 4 mm, including the end values, such as any one of 2.0 mm, 2.1 mm, 2.4 mm, 3.0 mm, 3.5 mm, and 4.0 mm. In the preferred embodiment, the water laying member 30 is spaced apart from the upper surface of the battery piece 01 to be processed by the first distance, and the range of the first distance is given. In the above range, the water laying member 30 is not in contact with the upper surface of the battery piece 01 to be processed, but the first distance is usually smaller than the thickness of the water film 02, and the water laying member 30 directly pushes the upper half of the water film 02 to lay on the upper surface, which can further improve the coverage of the water film 02 on the upper surface and improve the protection effect.

[0052] Of course, in actual situations, the water laying member 30 can be at least one of a scraper or an upper pressing roller, and only the scraper or the upper pressing roller can be provided, or both of them can be provided. The scraper and the upper pressing roller both have good effects of laying the water film 02, and of course, other types of water laying members 30 can be selected according to actual situations, which will not be described herein.

[0053] Further, the projection of the water laying member 30 on the transmission assembly 10 penetrates the projection of the battery piece 01 to be processed on the transmission assembly 10. In the preferred embodiment, the coverage width of the water laying member 30 is limited to be greater than the width of the battery piece 01 to be processed, so as to ensure that the water laying member 30 completely covers the upper surface of the battery piece 01 to be processed, thereby further ensuring that the sweeping and laying of the water film 02 will cover all positions of the upper surface, and further improving the coverage of the water film 02 on the upper surface.

[0054] The water laying assembly (such as the wheel shell structure of the upper pressing roller and the plate structure of the scraper) in the water laying piece 30 can be installed on the mounting rod 31 by sleeving or hanging, etc., and the mounting rod 31 is fixed to the water laying piece 30 by inserting the protruding ends 31A at both ends into the receiving space 41A of the edge fixing piece 40, without the need to install the water laying piece 30 directly above the space-limited conveying assembly 10, greatly reducing the difficulty and time consumption of replacing and spacing adjustment of the water laying piece 30 when different batches and different parameter requirements of the battery pieces 01 to be processed are sprayed with the water film 02, and greatly improving the application range of the utility model. For reference Figure 1 , Figure 1 The structure diagram of the mounting rod 31 after being inserted into the edge fixing piece 40. Of course, in other embodiments, the mounting rod itself constitutes a water laying piece. Therefore, the structure of the water laying piece is not limited in the utility model, as long as it can flatten the water film on the battery piece 01 to be processed.

[0055] In addition, the specific embodiment further indicates that the first mounting piece is an adjusting bolt 43; the adjusting bolt 43 penetrates the protruding end 31A in the height direction, and is used for adjusting the height of the protruding end 31A in the receiving space 41A. For reference Figure 5 , Figure 5 The side view of the mounting rod 31, the adjusting bolt 43 passes through the sleeving body 41 and is inserted into the protruding end 31A, so that the protruding end 31A (equivalent to the mounting rod 31) moves up and down in the receiving space 41A along with the rotation of the adjusting bolt 43, thereby adjusting the distance between the water laying piece 30 and the upper surface of the battery piece 01 to be processed, and improving the working stability.

[0056] According to the foregoing, preferably, the receiving space 41A is a waist-shaped sleeving hole. By Figure 5 As shown in the sectional view of the protruding end 31A and the receiving space 41A, the waist-shaped sleeving hole is a long hole with symmetrical ends and a parallel line formed in the middle, and preferably, the protruding end 31A can also be a waist-shaped protruding end 31A with symmetrical ends and a parallel line formed in the middle.

[0057] When the waist-shaped protruding end 31A is sleeved in the waist-shaped sleeving hole, the waists of the two are parallel to each other, and the waist of the waist-shaped sleeving hole limits the rotation of the waist-shaped protruding end 31A in the waist-shaped sleeving hole, so that the alignment difficulty of the adjusting bolt 43 in the installation process is greatly reduced, and the waist-shaped protruding end 31A is supported during the rotation of the adjusting bolt 43, avoiding the rotation of the waist-shaped protruding end 31A along with the adjusting bolt 43.

[0058] Further, the first mounting member further comprises a first fastening nut;

[0059] The first fastening nut is used to lock the relative position of the protruding end 31A and the adjusting bolt 43.

[0060] With the first fastening nut, the position of the adjusting bolt 43 in the accommodation space 41A can be locked, avoiding the accidental rotation of the adjusting bolt 43 due to the scratching or vibration of the battery piece 01 during use, affecting the height of the water spreading member 30, thereby further improving the working stability of the device. Specifically, two first fastening nuts are respectively screwed with the adjusting bolt 43 to mount it on the sleeve body 41, one of the first fastening nuts is used to mount the upper end of the adjusting bolt 43 on the sleeve body 41, and the lower end of the adjusting bolt 43 is screwed with the other first fastening nut after passing through the protruding end 31A, thereby achieving the suspension installation of the water spreading member 30 on the edge fixing member 40. Of course, in other embodiments, one end of the adjusting bolt 43 is in a T-shaped structure, so that the adjusting bolt 43 is mounted on the sleeve body 41 through the T-shaped structure, and the lower end of the adjusting bolt 43 is screwed with the other first fastening nut after passing through the protruding end 31A, thereby achieving the suspension installation of the water spreading member 30 on the edge fixing member 40. Of course, the lower end of the adjusting bolt 43 can be in the T-shaped structure to support the water spreading member 30, and then the upper end of the adjusting bolt 43 is screwed with the first fastening nut after passing through the protruding end 31A and the sleeve body 41 in turn, thereby achieving the suspension installation of the water spreading member 30 on the edge fixing member 40. In actual application, the height adjustment of the water spreading member 30 in the accommodation space can be achieved by rotating the first fastening nut on the adjusting bolt 43, thereby achieving the first distance between the water spreading member 30 and the battery piece 01, and further ensuring the water spreading effect.

[0061] Further, the radial direction of the installation fixing hole 42A is perpendicular to the radial direction of the mounting rod 31. This can ensure that when the edge fixing member 40 is fixed through the installation fixing hole 42A, the insertion direction of the second mounting member is perpendicular to the insertion direction of the mounting rod 31 (or the protruding end 31A) into the edge fixing member 40, providing more installation space for the second mounting member and reducing the installation difficulty of the edge fixing member 40. The three views of the edge fixing member 40 can be seen in Figure 6 、 Figure 7 and Figure 8 , wherein Figure 6 is the front view of the edge fixing member 40, and the connection part of the protruding end 31A and the edge fixing member 40 is also drawn, Figure 7 is the top view of the edge fixing member 40, Figure 8 is the right view of the edge fixing member 40.

[0062] Further, in the width direction of the conveying assembly 10, the hanging rod 31 of a single water spreading piece 30 penetrates the conveying assembly 10.

[0063] That is, the water spreading pieces 30 for processing the battery pieces 01 at different positions of the conveying assembly 10 are all arranged on the same hanging rod 31, which can further simplify the structure of the battery piece production device, reduce the cost of the device, and at the same time, ensure that the edge fixing piece 40 is located on the outer side of the conveying assembly 10, which is beneficial to improve the installation efficiency and the component replacement efficiency.

[0064] Further, a plurality of water spreading pieces 30 are arranged along the conveying direction.

[0065] As shown in Figure 9 In the preferred embodiment, an arrangement of the water spreading pieces 30 is specifically given. After the battery piece 01 is sprayed with water on the upper surface by the spraying assembly 20, the water film 02 on the upper surface is scraped by multiple water spreading pieces 30, which further improves the uniformity of the water film 02 on the upper surface and the coverage rate of the water film 02 on the upper surface, so as to achieve better protection effect on the upper surface of the battery piece 01 during subsequent acid etching.

[0066] As a preferred embodiment, at least one of the installation fixing holes 42A is a strip-shaped through hole;

[0067] The second mounting member includes a mounting bolt and a second fastening nut;

[0068] The mounting bolt penetrates the strip-shaped through hole and the installation surface, and by changing the relative position of the mounting bolt and the strip-shaped through hole, the position of the edge fixing piece 40 in the plane perpendicular to the height direction is changed.

[0069] The second fastening nut is arranged on the side of the installation surface away from the edge fixing piece 40, and is sleeved outside the mounting bolt, for locking and fixing the relative position of the edge fixing piece 40 and the installation surface.

[0070] For reference Figure 7The strip-shaped through hole can extend along the transmission direction or extend perpendicularly to the transmission direction, so as to change the installation position of the edge fixing member 40, facilitate adjustment of the position of the water distribution member 30 in the plane perpendicular to the height direction. Meanwhile, the second installation member is further defined as a combination of an installation bolt and a second fastening nut, so as to facilitate fixing of the relative position between the installation surface and the edge fixing member 40 by the second fastening nut after the relative position is determined by the installation bolt. When adjustment is needed later, only the second fastening nut needs to be loosened, and the installation bolt is adjusted and then the second fastening nut is tightened, so that the adjustment efficiency of the position of the water distribution member 30 is improved.

[0071] In other embodiments, the adjusting bolt 43 can move in the plane perpendicular to the height direction to replace or cooperate with the second installation member to adjust the position of the edge fixing member in the plane perpendicular to the height direction, which is different from the above-mentioned embodiments. In this embodiment, the second installation member only serves to detachably install the edge fixing member 40, and the position adjustment is realized by moving the first installation member in the plane perpendicular to the height direction. Specifically, the sleeve body is provided with a through hole corresponding to the first installation member, which can extend along the transmission direction to form a long hole or extend along the direction perpendicular to the transmission direction to form a long hole. Thus, the installation position of the water distribution member 30 is adjusted in the horizontal direction by changing the horizontal installation position of the first installation member (i.e., the adjusting bolt 43), and the installation height of the water distribution member is adjusted in the height direction by changing the installation position of the water distribution member 30 on the first installation member. In this embodiment, the installation fixing hole 42A can be a circular hole matched with the second installation member, which only serves to install and does not serve to adjust the installation position of the water distribution member 30.

[0072] Of course, in other embodiments, the installation fixing hole 42A can also be a strip-shaped hole to realize adjustment of the installation position of the water distribution member 30 by the second installation member. Specifically, when the extension directions of the installation fixing hole 42A and the through hole are the same, the installation positions of the water distribution member 30 are adjusted in the same direction by the two to realize greater distance adjustment of the water distribution member in the same direction. In other embodiments, when the extension directions of the installation fixing hole 42A and the through hole are different, the installation positions of the water distribution member 30 are adjusted in different directions by the two to realize more flexible adjustment of the water distribution member and meet more application scenarios.
