Description

Technical Field

[0001] The utility model relates to the field of solar cell production, in particular to a solar cell glue coating device and glue coating equipment with the glue coating device. Background Art

[0002] The production process of solar cells involves the process of coating the cells with glue. For example, in the process of preparing grid lines on the cells by electroplating, the sides of the cells will be exposed to the electroplating solution, so that the sides of the cells are also plated with metal, which can easily cause short circuits in the cells. In addition, the coating on the sides of the cells is not firmly connected to the cells, which causes the metal particles in the coating to easily fall off and transfer to the NP surface of the cells with the electroplating solution, causing pollution and affecting the yield and efficiency of the cells. Therefore, it is necessary to coat the sides of the cells (including the sides of the cells, the edges of the front side, and the edges of the back side, collectively referred to as the sides) with glue to form a protective layer to protect the sides of the cells from being electroplated, wherein the protective glue is wrapped around the sides of the cells by glue coating equipment, and a coating structure is formed after solidification to ensure that the glue forms a uniform and stable protective film on the sides of the cells.

[0003] The glue coating devices or glue dispensing devices currently on the market can only apply glue to the sides of a single battery cell, resulting in low production efficiency and high production costs. At the same time, due to the size error of each battery cell, when glue is applied to the same side of multiple battery cells at the same time, the glue coating effect is poor, and the sides of some battery cells will be unevenly coated or cannot be completely coated.

It does not necessarily belong to the prior art of this patent application. In the absence of clear evidence that the above content has been disclosed before the filing date of this patent application, the above background technology should not be used to evaluate the novelty and creativity of this application.

[0048] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and features of the utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only part of the embodiments of the application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0049] Referring to the battery cell gluing device shown in the drawings, the gluing device 100 includes a gluing assembly 10 for gluing the side edge 201 of the battery cell 20, wherein the side edge 201 of the battery cell 20 includes the edge of the front side of the battery cell, the edge of the back side of the battery cell, and the side of the battery cell, and the front side of the battery cell and the back side of the battery cell are two surfaces in the thickness direction of the battery cell 20. Since the size of each battery cell may have errors, when the same side edge 201 of multiple battery cells 20 is automatically and batch-glued, the distance between the gluing assembly 10 and the side edge 201 to be glued is inconsistent, which easily causes uneven gluing or incomplete gluing, resulting in poor gluing effect.

[0050] See also Figures 1 to 5 As shown, the glue coating assembly 10 includes a glue coating head 1, on which a receiving groove 12 and a glue outlet 15 are provided, and the receiving groove 12 and the glue outlet 15 are communicated with each other, wherein the receiving groove 12 has a first side wall 121 and a second side wall 122 arranged opposite to each other, and a bottom wall 123 connected between the first side wall 121 and the second side wall 122, and the receiving groove 12 also has an opening 124, and the opening 124 is arranged opposite to the bottom wall 123. When the glue coating head 1 and the side edge 201 of the battery cell 20 cooperate with each other, the battery cell 20 is inserted into the opening 124, and at least a part of the side edge 201 is located in the receiving groove 12 and between the first side wall 121 and the second side wall 122 along the thickness direction, and the bottom wall 123 is opposite to the side surface of the side edge 201.

[0051] The glue coating assembly 10 also includes a mounting member 2 and an elastic member 3. The glue coating head 1 can be moved in a linear direction and is arranged on the mounting member 2. The elastic member 3 is configured to provide the force required for the glue coating head 1 to reciprocate linearly on the mounting member 2, specifically, to provide the force required for the glue coating head 1 to move linearly from the bottom wall 123 toward the opening 124.

[0052] During the gluing process, under the action of the elastic member 3, the gluing head 1 remains in a relaxed and extended state, so that the accommodating groove 12 remains in cooperation with the side 201, so that the side 201 of the battery cell 20 can be fully glued; when the size of the battery cell 20 is slightly larger, after the side 201 enters the accommodating groove 12, the side 201 abuts against the gluing head 1, so that the gluing head 1 moves away from the battery cell 20 under the action of the elastic member 3, thereby avoiding the bottom wall 123 from colliding with the battery cell 20 and reducing the risk of fragments. Specifically, the elastic member 3 is a spring, which is sleeved on the outer wall of the mounting member 2.

[0053] To facilitate the description of the relative position relationship of each component, the direction in which the first side wall 121 and the second side wall 122 are spaced apart is defined here as the first direction, and the direction in which the bottom wall 123 and the opening 124 are spaced apart is defined here as the second direction. The above-mentioned first direction and the second direction are two directions perpendicular to each other, wherein the glue coating head 1 can be set on the mounting member 2 for linear movement along the above-mentioned second direction.

[0054] The receiving groove 12 penetrates along the gluing direction, and the first side wall 121 and the second side wall 122 extend along the gluing direction. The gluing direction is perpendicular to the first direction and the second direction. The glue outlet 15 can be specifically set on at least one of the bottom wall 123, the first side wall 121 and the second side wall 122. During the gluing process, the side edge 201 to be coated of the battery cell 20 passes through the receiving groove 12 along the gluing direction, so that different parts of the side edge 201 pass through the receiving groove 12 in turn and receive the gluing process.

[0055] In a preferred example, the glue outlet 15 is provided on the bottom wall 123, and the opening 124 extends along the length direction of the glue coating head 1 and directly connects to the glue outlet 15. Figure 3 As shown, in another preferred example, there are two glue outlets 15 and they are respectively arranged on the first side wall 121 and the second side wall 122, and the glue coating cavity 11 and the glue outlet 15 are connected through the glue outlet channel 111; accordingly, the glue is applied to the front and back surfaces of the battery cell 20 respectively, which not only makes the coating of the glue on the side more uniform, but also makes the contact area between the glue outlet 15 and the external air smaller, so that the glue in the accommodating groove 12 is not easy to solidify, thereby avoiding the solidified glue from damaging the battery cell 20 or affecting the smooth outflow of the glue from the glue outlet 15; in addition, the glue outlet 15 can also be respectively arranged on the bottom wall 123, the first side wall 121 and the second side wall 122 to cope with the situation where the demand for glue is large.

[0056] In some examples, the glue outlet 15 is composed of a single hole, and the flow rate and flow velocity of the glue flowing out through the single hole are relatively fixed. Directly affected by factors such as the size of the hole and the pressure of the glue, the glue flowing out through the single hole usually forms a more concentrated flow beam, and the flow pattern is relatively simple, which can only cover a limited range, and the distribution of the glue in the receiving groove 12 may not be uniform enough; in another example, the glue outlet 15 is composed of multiple dense holes. The total flow rate of the glue flowing out through the dense holes may increase, but the flow rate and flow velocity of each hole may be affected by the diversion, making the overall flow rate more uniform.

[0057] Specifically, see Figures 1 to 3As shown, the glue coating head 1 has a connecting end 1A and a glue coating end 1B, and the connecting end 1A and the glue coating end 1B are respectively arranged at different ends in the length direction of the glue coating head 1, and the accommodating groove 12 and the glue outlet 15 are both arranged in the glue coating end 1B. Here, the length extension direction of the glue coating head 1 is the second direction, and the glue coating head 1 can be slidably set on the mounting member 2 along its own length direction.

[0058] In some embodiments, Figure 4 , Figure 5 As shown, the glue coating head 1 also includes a flexible protective member 13, which is made of a flexible material, and the flexible protective member 13 at least covers the outer side of the glue coating end 1B, so that when the glue coating end 1B contacts the battery cell 20, it will not cause an impact on the battery cell 20 and cause fragments. The material of the flexible protective member 13 can be silicone, rubber, etc., as long as it does not damage the battery cell 20 when it collides with the battery cell 20, and no specific restrictions are made here. In other embodiments, the glue coating head 1 can also be set as a flexible glue coating head (not shown in the figure), which can be directly slidably set on the mounting member 2 along its own length direction, and avoids causing damage to the battery cell 20 when it contacts the battery cell 20.

[0059] See also Figures 1 to 5 As shown, the glue coating head 1 is provided with a glue coating chamber 11, which is connected to the glue outlet 15. The glue in the glue coating chamber 11 enters the receiving groove 12 through the glue outlet 15, and is then coated on the side edge 201 of the battery cell 20 to be coated. Fig. 9 , Fig.10 As shown, the glue coating device 100 also includes a glue storage device 4 having a glue storage cavity, and the mounting member 2 is fixedly mounted on the glue storage device 4 . The glue storage cavity and the glue coating cavity 11 are connected to each other via a connecting cavity 23 , and the connecting cavity 23 is disposed on the mounting member 2 .

[0060] Specifically, the glue coating cavity 11 extends along the length extension direction of the glue coating head 1, one end of the mounting member 2 is fixedly arranged on the glue storage device 4, and the other end of the mounting member 2 is slidably inserted into the glue coating cavity 11. Here, the mounting member 2 includes a mounting body 21, and a limiting protrusion 22 provided at one end of the mounting body 21 and protruding outward from the outer peripheral portion of the mounting body 21. A through hole is provided on the connecting end 1A, and the mounting body 21 is inserted into the above-mentioned through hole in a slidable manner, and the limiting protrusion 22 is inserted into the glue coating cavity 11 in a slidable manner. Further, a limiting portion 14 extending inwardly is provided on the inner peripheral portion of the through hole to limit the sliding of the limiting protrusion 22 of the mounting body 21 in the glue coating cavity 11, so as to prevent the mounting body 21 from sliding out of the glue coating cavity 11. In the specific setting, the outer peripheral wall of the limiting protrusion 22 and the inner cavity wall of the glue coating cavity 11 should be kept sealed to prevent the glue from flowing out from the gap between the two.

[0061] In other embodiments, the glue coating head 1 and the mounting member 2 may not be arranged in the above manner. Specifically, the mounting member 2 does not have a chamber connecting the glue storage chamber and the glue coating chamber 11. Instead, a glue delivery pipe with a hollow lumen is arranged between the glue storage device 4 and the glue coating head 1, and the hollow lumen of the glue delivery pipe constitutes a connecting chamber connecting the glue storage chamber and the glue coating chamber 11.

[0062] See also Fig. 9 , Fig.10 As shown, the glue coating device 100 further includes an extrusion member 5 and an extrusion driving member (not shown in the figure), the extrusion member 5 is slidably disposed in the glue storage cavity and divides the glue storage cavity into a first cavity 41 and a second cavity 42, the first cavity 41 is connected to the connecting cavity 23, and the extrusion driving member is configured to drive the extrusion member 5 to slide. During the glue coating process, the extrusion driving member drives the extrusion member 5 to slide toward the first cavity 41, so that the glue in the first cavity 41 is squeezed out and enters the glue coating cavity 11 through the connecting cavity 23, and then reaches the receiving groove 12 through the glue outlet 15, and then the side 201 of the battery cell located in the receiving groove 12 is glued.

[0063] In some embodiments, Fig.10 As shown, the shape and size of the extrusion member 5 and the glue storage cavity of the glue storage device 4 are adapted, so that when the extrusion member 5 squeezes the glue liquid and slides toward the first cavity 41, the glue liquid can only flow out through the connecting cavity 23, thereby preventing the glue liquid from remaining in the second cavity 42. Preferably, the glue storage cavity is a regular rectangular cavity, and the extrusion member 5 is a rectangular plate adapted to the rectangular cavity, and the edge of the rectangular plate is made of a flexible material, thereby preventing the glue liquid from remaining on the side wall of the glue storage cavity during the extrusion process.

[0064] Specifically, the extrusion member 5 also includes an extrusion push rod 6, one end of which is connected to the extrusion member 5, and the other end passes through the glue storage container 4 and is connected to the working end of the extrusion drive member. When the size of the glue storage container 4 is large, the extrusion push rod 6 can also be set to be multiple and spaced apart.

[0065] In some embodiments, the glue coating device 100 may include a set of glue coating components 10, such as Figure 7 In other embodiments, the gluing device 100 may also include multiple groups of gluing components 10, such as Fig. 9 As shown, all the glue-coated components 10 are distributed at intervals in the first direction so as to simultaneously perform glue coating processing on the same side edges 201 of multiple battery cells 20 distributed at intervals along the first direction. It should be noted here that the spacing distance between two adjacent glue-coated components 10 is equal to the spacing distance between two adjacent battery cells 20.

[0066] The utility model also provides a battery cell gluing device, which includes the above-mentioned gluing device 100, and also includes a carrier 50 and a transmission device, wherein the carrier 50 has a carrier table 501 for carrying the battery cell 20, when the battery cell 20 is carried on the carrier table 501, the side edge 201 of the battery cell 20 to be glued is located on the circumferential outside of the carrier table 501, when the carrier 50 is in the gluing station, the side edge 201 of the battery cell 20 corresponds to the gluing component 10.

[0067] In some embodiments, when the glue coating device 100 includes a plurality of glue coating components 10 arranged at intervals along the first direction, the carrier 50 is correspondingly configured as a multi-layer structure. Fig. 9 , Fig.11 As shown, the carrier 50 includes a plurality of carriers 501, all of which are spaced apart along a first direction and connected by brackets 502, the brackets 502 do not contact the battery cells 20, and do not affect the gluing of the side edges 201 of the battery cells. When the carrier 50 is in the gluing station, the side edges 201 of the plurality of battery cells 20 correspond one-to-one with the plurality of groups of gluing components 10.

[0068] The wafer carrier 501 specifically includes a wafer carrier body 501a and an adsorption head 501b arranged on the wafer carrier body 501a, wherein the adsorption head 501b is configured to be able to adsorb and fix the battery cell 20, wherein the adsorption head 501b can rotate around a first center line so that multiple side edges 201 of the battery cell 20 respectively cooperate with the glue coating component 10, and the first center line extends along a first direction; or, the carrier 50 is configured to be able to be rotatably arranged around a second center line so that multiple side edges 201 of the battery cell 20 respectively cooperate with the glue coating component 10, and the above-mentioned second center line also extends along the first direction.

[0069] The transmission device may be Figure 6 , Fig.14 The linear transmission mechanism 30 shown in FIG. Figure 8 , Fig.12 The turntable 40 shown, wherein, when a linear transmission mechanism 30 is adopted, the linear transmission mechanism 30 is configured to drive the carrier 50 and the gluing device 100 to move linearly relative to each other along the gluing direction; when a turntable 40 is adopted, the turntable 40 is configured to be able to rotate around a rotation center line extending in a vertical direction, and a workbench for carrying the carrier 50 is provided on the turntable 40, and the turntable 40 passes through the gluing station during the rotation around the above-mentioned rotation center line.

[0070] The working process of each embodiment is described in detail below:

[0071] Example 1

[0072] See also Figure 6 , Figure 7As shown, the glue coating equipment of this embodiment performs glue coating on the side edge 201 of the single battery cell 20 .

[0073] In this embodiment, in the glue coating device 100, the length extension direction of the glue coating head 1 extends in the horizontal direction, that is, the first direction is the vertical direction, the second direction is the horizontal direction, and the glue coating direction is another horizontal direction perpendicular to the second direction. During the glue coating process, the thickness direction of the battery cell 20 to be glued extends in the vertical direction, and the battery cell 20 is kept in the horizontal direction for transmission and cooperates with the glue coating component 10 of the glue coating device 100.

[0074] The transmission device specifically adopts a linear transmission mechanism 30, which has a first station 301, a rotating station 302 and a second station 303 distributed in sequence along the transmission direction. The transmission component 304 is configured to transmit the carrier 50, where the carrier 50 is a single-piece carrier 501. The transmission direction of the linear transmission mechanism 30 is also the gluing direction. The gluing device 100 is provided with four groups, two of which are respectively provided on both sides of the first station 301, and the other two are respectively provided on both sides of the second station 303.

[0075] Each set of gluing devices 100 also includes a lifting mechanism 101 and a translation mechanism 102. Here, the gluing component 10 is arranged on the lifting mechanism 101 and the height is adjusted by the lifting mechanism 101. The translation mechanism 102 is used to drive the lifting mechanism 101 to translate, so as to adjust the relative position of the gluing head 1 in the gluing component 10 and the side 201 of the battery cell to be glued in the second direction, so that the side 201 can be inserted into the receiving groove 12 to receive glue.

[0076] In one example, during the gluing process, a single cell 20 can be directly transferred through a transmission component 304, and a rotatable turntable 305 is also provided on the transmission component 304. When the cell 20 passes through the first station 301, two groups of gluing devices 100 apply glue to one group of opposite sides 201 of the same cell 20; after the gluing is completed, the cell 20 is rotated 90° by the turntable 305 at the rotation station 302, so that the other group of opposite sides 201 can be converted to extend along the gluing direction; then, the transmission component 34 transfers the cell 20 to the second station 303, and the corresponding two groups of gluing devices 100 apply glue to the other group of opposite sides 201 of the cell 20, thereby completing the gluing of the four sides 201 of the entire cell 20.

[0077] In another example, during the gluing process, a single battery cell 20 can be placed on a carrier 50 with only a single-layer structure, and the transmission component 304 transmits the battery cell by transmitting the carrier 50 carrying the battery cell 20; or a single battery cell 20 can be placed on any layer of a carrier 50 with a multi-layer structure. In this case, the height position of the gluing component 10 needs to be pre-adjusted by the lifting mechanism 101 to correspond to the specific position of the battery cell 20. When the battery cell 20 passes through the first workstation 301, two groups of glue coating devices 100 coat one group of opposite sides 201 of the same battery cell 20 with glue; after the gluing is completed, the battery cell 20 is rotated 90° by the carrier 501 at the rotating workstation 302, so that the other group of opposite sides 201 can be converted to extend along the gluing direction; then, the transmission component 34 transmits the battery cell 20 to the second workstation 303 through the carrier 50, and the corresponding two groups of glue coating devices 100 coat the other group of opposite sides 201 of the battery cell 20, thereby completing the gluing of the four sides 201 of the entire battery cell 20.

[0078] Example 2

[0079] See also Figure 8 As shown, the main difference between this embodiment and embodiment 1 is that the transmission device in this embodiment adopts a turntable 40, and the turntable 40 is configured to be able to rotate around a rotation center line extending in the vertical direction. The carrier stage 501 on the carrier 50 can be directly set on the turntable 40, and multiple carrier stages 501 are arranged on the turntable 40 at intervals along the circumferential direction.

[0080] Four gluing stations are arranged on the rotating path of the turntable 40, namely, the first gluing station 401, the second gluing station 402, the third gluing station 403 and the fourth gluing station 404. A group of gluing devices 100 are arranged next to each gluing station to perform gluing on the four side edges 201 of the battery cell 20 respectively. Before each battery cell 20 enters a gluing station, it is necessary to drive the carrier stage 501 to rotate 90°, or drive the adsorption head 501b on the carrier stage 501 to drive the battery cell 20 to rotate 90°, so as to switch the side edge 201 to be glued.

[0081] In one example, during the gluing process, each time the battery cell 20 enters a gluing station, the gluing assembly 10 set on the lifting mechanism 101 is driven by the translation mechanism 102 to perform gluing along the side 201 to be glued of the battery cell 20, so that the gluing of the four sides 201 of the entire battery cell 20 is completed in sequence.

[0082] In another example, during the gluing process, the battery cell 20 rotates 90° before entering each gluing station, and the turntable 40 contacts the gluing head 1 of the gluing assembly 10 on the rotating path, and the gluing of the side 201 to be glued on the rotating path is completed by the extension and contraction of the elastic member 3.

[0083] Example 3

[0084] See also Figures 9 to 12 As shown, the glue coating equipment of this embodiment can perform glue coating on the side edges 201 of multiple battery cells 20. The carrier 50 adopts a structure of a multi-layer wafer carrier 501, and the glue coating device 100 includes a plurality of groups of glue coating components 10 spaced apart along a first direction. On the carrier 50, the adsorption heads 501b on each layer of wafer carrier 501 can rotate around a first center line extending along the first direction, so that the battery cell 20 can rotate and switch the side edges 201 that cooperate with the glue coating device 100, so that different side edges 201 cooperate with the glue coating device 100 for glue coating.

[0085] See also Fig.12 As shown, in this embodiment, a turntable 40 is used to transfer the carrier 50. Four gluing stations are arranged on the turntable 40, namely, the first gluing station 401, the second gluing station 402, the third gluing station 403, and the fourth gluing station 404. A group of gluing devices 100 are arranged beside each of the gluing stations 401, 402, 403, and 404, respectively, to perform gluing on the four sides 201 of the battery cell 20. Before each battery cell 20 enters a gluing station, multiple battery cells 20 need to be rotated 90°. Specifically, the battery cell 20 can be rotated by driving the rotation of the adsorption head 501b. At the same time, a rotating table can be arranged on the turntable 40 to drive the carrier 50 to rotate as a whole. However, in this method, it should be noted that when applying glue, the gluing device 100 should avoid contacting with the bracket 502 so as not to affect the gluing of the sides 201 of the battery cell. Other gluing processing methods are the same as the gluing processing in Example 2.

[0086] Example 4

[0087] See also Figure 13 to Figure 14 As shown, the gluing equipment of this embodiment is different from that of Embodiment 3 mainly in that the transmission device of this embodiment adopts a linear transmission mechanism 30, which has a first station 301, a rotating station 302 and a second station 303 sequentially distributed along the transmission direction, and the transmission component 304 is configured to be used for transmitting the carrier 50. The gluing device 100 is provided with four groups, two of which are respectively arranged on both sides of the first station 301, and two of which are respectively arranged on both sides of the second station 303.

[0088] During the gluing process, the carrier 50 carrying the battery cells 20 is transported by the transmission component 304. When passing through the first station 301, the two groups of gluing devices 100 apply glue to one group of opposite sides 201 of the multiple battery cells 20. After the gluing is completed, the carrier 501 carrying the battery cells 20 is transported to the rotating station 302. At the rotating station 302, the rotation of each adsorption head 501b on the carrier 50 drives each battery cell 20 to rotate 90 degrees, so that another group of opposite sides 201 are converted to extend along the gluing direction. Then, the transmission component 34 transfers the carrier 50 carrying the battery cells 20 to the second station 303, and the corresponding two groups of gluing devices 100 apply glue to the other group of opposite sides 201 of the battery cells 20. In this way, the gluing of the four sides 201 of the multiple battery cells 20 is completed.

[0089] The utility model provides a battery cell gluing device and a gluing equipment, wherein the gluing device 100 includes a gluing component 10 for gluing the side 201 of the battery cell 20, the gluing component 10 includes a gluing head 1, the gluing head 1 is provided with a receiving groove 12 and a glue outlet 15, the receiving groove 12 and the glue outlet 15 are connected to each other, the gluing component 10 also includes a mounting member 2 and an elastic member 3, the gluing head 1 can be movably arranged on the mounting member 2 in a linear direction, and the elastic member 3 is configured to provide the force required for the gluing head 1 to reciprocate linearly on the mounting member 2. Compared with the prior art, the battery cell gluing device and gluing equipment of the utility model have the following advantages: in the process of gluing one side of a single battery cell 20, or the same side 201 of multiple battery cells 20, when the side 201 of the battery cell 20 to be glued cooperates with the gluing component 10, the gluing head 1 in the gluing component 10 can be elastically retracted, while ensuring that the side 201 of the battery cell 20 can cooperate well with the accommodating groove 12, and at the same time, avoiding the risk of fragments caused by the bottom wall of the accommodating groove 12 hitting the side 201 of the battery cell, thereby improving the gluing quality.

Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
