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] Conventional glue coating devices on the market can usually only evenly coat glue on battery cells with a high degree of flatness. However, for battery cells that are partially warped, uneven glue coating is prone to occur. The glue thickness on the same battery cell is uneven, and the glue coating head on the glue coating device may also collide with the warped part, increasing the risk of fragmentation.

[0037] 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.

[0038] The battery cell gluing device provided by the utility model is used 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. During the production process of the battery cell 20, even for the same battery cell 20, the degree of warping at different positions of each side edge is different. If the conventional gluing device on the market is used for gluing, it is easy to have uneven thickness of the glue on the same battery cell 20. At the same time, the gluing head on the gluing device may collide with the warped part, increasing the risk of fragmentation. In particular, when the same side edge 201 of multiple battery cells 20 is automatically and batch-processed, the uneven gluing phenomenon is more significant, and the fragmentation rate is also significantly increased.

[0039] Referring to the battery cell gluing device shown in the drawings, the gluing device 100 includes a gluing assembly 10 , which is used to cooperate with the battery cell 20 to perform gluing processing on the side edge 201 thereof.

[0040] The glue coating assembly 10 includes a glue coating head 1, on which a receiving groove 13 and a glue outlet 16 are provided, and the receiving groove 13 and the glue outlet 16 are connected to each other, wherein the receiving groove 13 has a first side wall 131 and a second side wall 132 arranged at intervals along a first direction, and when the glue coating head 1 and the side edge 201 of the battery cell 20 cooperate with each other, the thickness direction of the battery cell 20 extends along the first direction, that is, the front and back sides of the battery cell 20 are respectively facing the first side wall 131 and the second side wall 132. Specifically, see Figures 1 to 3As shown, the accommodating groove 13 also has an opening and a bottom wall 133 connected between the first side wall 131 and the second side wall 132, and the opening and the bottom wall 133 are spaced apart in a second direction, and the second direction is perpendicular to the first direction. 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 in the opening, and at least a part of the side edge 201 is located in the accommodating groove 13 and between the first side wall 131 and the second side wall 132 along the thickness direction, and the bottom wall 133 is opposite to the side of the side edge 201.

[0041] More specifically, the accommodating groove 13 penetrates along the gluing direction, and the first side wall 131 and the second side wall 132 extend along the gluing direction. The gluing direction is perpendicular to the first direction and the second direction. The dimension of the accommodating groove 13 along the gluing direction is much smaller than the length dimension of the side edge 201 in the single-chip battery cell 20.

[0042] The glue outlet 16 may be disposed on at least one of the bottom wall 133, the first side wall 131, and the second side wall 132. Figure 2 In the embodiment shown, the glue outlet 16 is disposed on the bottom wall 133; Figure 3 In the illustrated embodiment, both the first side wall 131 and the second side wall 132 are provided with a glue outlet 16; in other embodiments, the glue outlet 16 may also be provided only on the first side wall 131 or the second side wall 132, or the first side wall 131, the second side wall 132 and the bottom wall 133 are provided with a glue outlet 16. During the glue coating process, the glue liquid flowing out of the glue outlet 16 enters the receiving groove 13, and the side edge 201 to be coated of the battery cell 20 passes through the receiving groove 13 along the glue coating direction, so that different parts of the side edge 201 pass through the receiving groove 13 in turn and receive the glue coating process, so as to realize the glue coating on the side edge 201 of the battery cell 20. The specific type and viscosity of the glue liquid can be set according to actual needs, and no specific limitation is made here.

[0043] The glue coating assembly 10 also includes a mounting member 2 and an elastic member 3. The mounting member 2 has a mounting cavity 23. The elastic member 3 and the glue coating head 1 are movably arranged in the mounting cavity 23 of the mounting member 2 along a first direction, and the accommodating groove 13 and the glue outlet 16 on the glue coating head 1 are exposed outside the mounting cavity 23. The elastic member 3 is arranged between the glue coating head 1 and the mounting member 2. The elastic member is configured to provide the force required for the glue coating head 1 to reciprocate in the mounting cavity 23 along the first direction, so that the glue coating head 1 can reciprocate linearly in the first direction relative to the mounting member 2. Specifically, the elastic member 3 is configured to provide the force required for the glue coating head 2 to move from the first side wall 131 toward the second side wall 132 along the first direction, or the force required for the glue coating head 2 to move from the second side wall 132 toward the first side wall 131 along the first direction. This allows the glue coating head 1 to float in the first direction relative to the mounting member 2, so that the position can be adjusted according to the size of the side 201 of the battery cell to be glued, so as to avoid collision with the battery cell and cause fragments.

[0044] Specifically, during the process of glue coating, under the action of the elastic member 3, the glue coating head 1 keeps extending from the first side wall 131 toward the second side wall 132. During the relative movement between the battery cell 20 and the glue coating device 100, the side edge 201 of the battery cell 20 can enter the receiving groove 13 and be located between the first side wall 131 and the second side wall 132 to receive the glue coating process. When a certain part of the side edge 201 is warped, the side edge 201 will push up the first side wall 131 or the second side wall 132, so that the glue coating head 2 reciprocates along the first direction under the action of the elastic member 3, thereby allowing the side edge 201 to smoothly pass through the receiving groove 13 and achieve glue coating, while also preventing the first side wall 131 or the second side wall 132 from causing damage to the battery cell 20 and causing fragments.

[0045] See also Figures 1 to 3 As shown, as a preferred mode, the length extension direction of the glue coating head 1 extends along the first direction mentioned above, and the glue coating head 1 includes a glue storage body 11 and a glue coating body 12, the glue storage body 11 is provided with a glue storage cavity 14, and the glue coating body 12 is provided with a glue outlet channel 15, wherein the glue coating body 12 has a first end and a second end which are respectively arranged at two different ends of its length direction, the receiving groove 13 and the glue outlet 16 are both arranged on the first end, and the second end is connected to the glue storage body 11, and the glue outlet channel 15 connects the glue storage cavity 14 and the glue outlet 16. The glue storage body 11 and the glue coating body 12 can be arranged as a whole, preferably as a split arrangement, so that when the receiving groove 13 and / or the glue outlet 16 on the glue coating body 12 are damaged, the glue coating body 12 can be directly replaced.

[0046] One end of the mounting member 2 is also provided with a through hole 24 connected to the mounting cavity 23, the glue storage body 11 is slidably fitted in the mounting cavity 23, and the glue coating body 12 can be slidably fitted in the through hole 24 along the first direction. Specifically, the mounting member 2 includes a mounting body 21 having the above-mentioned mounting cavity 23, and a cover body 22 fixed to one end of the mounting body 21, the cover body 22 is used to close the mounting cavity 23 and to form a limit for the glue storage body 11. In one example, the through hole 24 is provided on the cover body 22; in another example, the through hole 24 is provided on the bottom wall of one end of the mounting member 2, and the cover body 22 is only used to close the other end of the mounting member 2. The elastic member 3 is provided in the mounting cavity 23, and here, the elastic member 3 is specifically a spring, which abuts between the bottom wall of the mounting cavity 23 and the glue storage body 11.

[0047] Although not shown, the glue coating device 100 further includes an extrusion mechanism for driving the glue in the glue storage body 11 to flow toward the glue outlet channel 15. For example, an extrusion member matching the size of the glue storage body 11 is provided in the glue storage body 11, and the extrusion member is driven to slide in the glue storage body 11 by an extrusion driving member, so that the glue can be input into the glue outlet channel 15. The glue coating device 100 further includes a glue pouring mechanism for pouring glue into the glue storage body 11. For example, a glue storage tank is provided outside the glue coating component 10, and the glue in the glue storage tank is driven to pour glue into the glue storage cavity 14 by a glue supply pump. The glue storage tank is connected to the glue storage cavity 14 through a hose. Specifically, one end of the hose is connected to one end of the glue storage body 11 away from the glue coating body 12, and the other end of the hose passes through the elastic member 3 and the bottom wall of the mounting member 2 to communicate with the glue storage tank.

[0048] The utility model also provides a battery cell gluing device, which includes the above-mentioned gluing device 100 and also includes a carrier (not shown in the figure) for carrying the battery cell 20. When the battery cell 20 is carried on the carrier, the side edge 201 of the battery cell 20 to be glued is located on the circumferential outside of the carrier. When the carrier carrying the battery cell 20 is in the gluing station, the side edge 201 of the battery cell 20 corresponds to the gluing component 10. At the same time, the thickness direction of the battery cell 20 extends along the first direction, and the side edge 201 is located between the first side wall 131 and the second side wall 132.

[0049] As a preferred setting mode, the first direction is the vertical direction, and the carrier is configured to extend in the horizontal direction, which makes it easier to transport the battery cell 20. The carrier may specifically include a carrier body and an adsorption head disposed on the carrier body, and the adsorption head is configured to be able to adsorb and fix the battery cell 20, so that the battery cell 20 can be synchronously transmitted with the carrier on the carrier without the risk of falling or shifting. In some embodiments, the adsorption head is further configured to be able to rotate around a first center line extending in the vertical direction, so that the multiple side edges 201 of the battery cell 20 respectively cooperate with the glue coating component 10; in other embodiments, the carrier can also be configured to be able to rotate around a second center line extending in the vertical direction, so that the multiple side edges 201 of the battery cell 20 respectively cooperate with the glue coating component 10.

[0050] The battery sheet glue coating device also includes a transmission device, which can be as follows Figure 4 The linear transmission mechanism 30 shown in FIG. Figure 6 The turntable 40 shown, wherein when a linear transmission mechanism 30 is adopted, the linear transmission mechanism 30 is configured to drive the carrier and the gluing device 100 to move linearly relative to each other in 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 the vertical direction, and a plurality of carriers are arranged on the turntable 40 at intervals along the circumferential direction to respectively carry the battery cells 20, and the turntable 40 passes through the gluing station during its rotation around the above-mentioned rotation center line.

[0051] By using the cell gluing device and cell gluing equipment of the utility model, during the process of gluing the same side of the cell 20, when the side of the cell 20 to be glued cooperates with the gluing assembly 10, the gluing head 1 in the gluing assembly 10 can reciprocate along the thickness direction of the cell 20, thereby allowing the side 201 to smoothly pass through the receiving groove 13 on the gluing head 1 and achieve gluing, improving the gluing uniformity, while also preventing the two opposite side walls on the receiving groove 13 from damaging the cell 20, reducing the risk of fragments. The gluing device and the gluing equipment are particularly suitable for gluing the side 201 of multiple cells 20 in an automated gluing production line.

[0052] The working process of each embodiment is described in detail below:

[0053] Example 1

[0054] See also Figure 4 , Figure 5 As shown, the glue coating equipment of this embodiment performs glue coating on the side edge 201 of the single battery cell 20 .

[0055] In this embodiment, in the glue coating device 100, the length extension direction of the glue coating head 1 extends in the vertical 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.

[0056] 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, and a transmission component 304 is configured to transmit the carrier. The glue coating device 100 is provided with four groups, two of which are respectively arranged on both sides of the first station 301, and the other two are respectively arranged on both sides of the second station 303.

[0057] Each set of glue coating devices 100 also includes a mounting frame and a position adjustment mechanism, wherein the position adjustment mechanism is configured to drive the mounting frame to adjust its height in the vertical direction and adjust its position in the horizontal direction. The mounting member 2 in the glue coating assembly 10 is fixed on the mounting frame, and the glue coating head 1 is located below the mounting member 2. Figure 5 Here, the position adjustment mechanism specifically includes a lifting mechanism 101 and a translation mechanism 102. Here, the glue coating assembly 10 is mounted 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 glue coating head 1 in the glue coating assembly 10 and the side 201 of the battery cell 20 to be glued in the second direction, so that the side 201 can be inserted into the receiving groove 13 to receive glue.

[0058] During the gluing process, the carrier carrying the battery cell 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 battery cell 20. After the gluing is completed, the carrier carrying the battery cell 20 is transported to the rotating station 302. At this time, the carrier is lifted up by the rotating table 305 and driven to rotate the entire carrier 90°, 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 carrier carrying the battery 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 battery cell 20. In this way, the gluing of the four sides 201 of the entire battery cell 20 is completed.

[0059] In other embodiments, when the carrier carrying the battery cell 20 is transferred to the rotating station 302, the driving member on the carrier can also be used to drive the adsorption head to rotate to drive the battery cell 20 to rotate, thereby switching the side 201 to be coated with glue.

[0060] Example 2

[0061] See also Figure 6 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 is directly arranged on the turntable 40, and a plurality of carriers are arranged on the turntable 40 at intervals along the circumferential direction.

[0062] 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 to drive the battery cell 20 thereon to rotate 90° together, or drive the adsorption head on the carrier to drive the battery cell 20 to rotate 90°, so as to switch the side edge 201 to be glued.

[0063] 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.

[0064] 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 to complete the gluing of the side 201 to be glued on the rotating path.

[0065] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. 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.
