Description

Technical Field

[0001] The utility model relates to the field of solar cell chip manufacturing, in particular to a cell chip glue coating device. Background Art

[0002] The demand for photovoltaic cell production equipment in the photovoltaic industry is also increasing, and higher requirements are also placed on the production capacity of the equipment. In the production process of photovoltaic cells, the process of coating the cell with glue is involved. For example, in the process of preparing the grid line on the cell by electroplating, the side of the cell will be exposed to the electroplating solution, so that the side of the cell is also plated with a coating, which will easily cause the cell to short-circuit; the coating on the side of the cell is not firmly connected to the cell, causing the metal particles in the coating to easily fall off and transfer to the NP surface of the cell with the electroplating solution, causing pollution and affecting the yield and efficiency of the cell; therefore, it is necessary to pre-coat the side of the cell with glue to form a protective layer to protect the side of the cell from being electroplated. For conventional rectangular cells, glue needs to be applied to the sides of the cell, chamfers, and the edges around the two surfaces. This process is also called the glue coating process of the cell. The process of conventional battery cells is to cut a whole piece of raw silicon wafer from the middle to become two half-pieces of silicon wafers, and then process the half-pieces of silicon wafers into battery cells. When cutting silicon wafers, a small amount is usually cut from the middle of one end of the silicon wafer inward, and the rest of the part naturally cracks due to the tension after cutting. The long sides formed by the cracking of the silicon wafer are prone to irregularity, that is, the two long sides are not parallel, forming special-shaped battery cells. In existing equipment, special-shaped battery cells are usually directly treated as regular battery cells for glue coating process, which will result in irregular glue coating on the special-shaped sides, and some areas cannot be completely coated with glue, which will affect the subsequent process of battery cells, reduce the yield of finished products, and cause a large amount of cost waste.

[0076] See also Figures 1 to 7 It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the utility model in a schematic manner, and the illustrations only show the components related to the utility model rather than the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0077] In order to facilitate the description and understanding of the specific structure of the cell gluing device, this embodiment constructs a three-dimensional space coordinate system in the cell gluing device, wherein the first direction X, the second direction Y and the up and down directions Z are perpendicular to each other, and the first direction X and the second direction Y extend in the horizontal direction respectively.

[0078] like Figure 1As shown, the applicant found that the process of conventional battery cells is to cut a whole raw silicon wafer 10 from the middle to become two half-chip silicon wafers 10, and then process the half-chip silicon wafer 10 into battery cells; when cutting the silicon wafer 10, a small amount is usually cut from the middle of one end of the silicon wafer 10 inward, and the rest of the part naturally cracks due to the tension after cutting. The long side edges formed by the cracking of the silicon wafer 10 are prone to be irregular, that is, the two long sides are not parallel, forming a special-shaped battery cell. In existing equipment, the special-shaped battery cell is usually directly treated as a regular battery cell for glue coating process, which will result in irregular side glue coating of the special-shaped battery cell, and some side areas cannot be completely coated with glue, which will affect the subsequent process of the battery cell, reduce the yield of the finished product, and cause a large amount of cost waste.

[0079] In view of the existing problems, such as Figures 2 to 3 As shown, this embodiment provides a battery cell gluing device, which includes: a visual positioning device 20, a gluing device and a transmission device 40; the visual positioning device 20 is correspondingly provided with a visual positioning station, and the visual positioning device 20 is configured to obtain the graphic parameters of the battery cell at the visual positioning station, and the specific graphic parameters refer to the edge contour shape and size of the battery cell; the gluing device is located downstream of the visual device, and the gluing device is correspondingly provided with a gluing station. In the working state, the gluing device is configured to perform gluing on the battery cell according to the obtained graphic parameters of the battery cell; the transmission device 40 is configured to transfer the battery cell to be glued from the visual positioning station to the gluing station. The battery cell gluing device also includes a control module to realize the automated overall control of the visual positioning device 20, the gluing device and the transmission device 40. The battery cell gluing device also includes a machine platform, which is configured to carry various devices on the battery cell gluing device.

[0080] The cell gluing equipment of the present embodiment obtains the graphic parameters of the cell to be glued by the visual positioning device 20, and performs glue coating on the cell according to the obtained graphic parameters of the cell through the gluing device. It can not only directly perform glue coating on conventional cell, but also fit multiple points on the irregular side of the irregular cell into a straight line edge, and compare the fitted straight line with the benchmark straight line, and calculate the position coordinate compensation value required for gluing the irregular side by comparison, and perform position compensation when gluing the irregular side by fitting result, so that the glue can be completely coated on the side of the cell, thereby improving the preparation yield of the cell and increasing the stability and continuity of the gluing process of the cell. Each device in the cell gluing equipment of the present embodiment has a compact structure, small footprint, and convenient maintenance, which reduces the failure rate and maintenance cost of the equipment.

[0081] In order to obtain the graphic parameters of the battery cell at the visual positioning station, such as Figures 4 to 5As shown, in a specific example that can be implemented, the visual positioning device 20 includes: a camera seat support frame 21, a camera fixing seat 22, a camera fixing part and a camera group; the camera fixing seat 22 is movably arranged on the camera seat support frame 21 along the up and down directions; the camera fixing part is movably arranged on the camera fixing seat 22 along the first direction Y; the camera group includes a plurality of cameras, and the cameras are movably arranged on the camera fixing part along the second direction Y, and the cameras are configured to photograph and position the battery cells to obtain the graphic parameters of the battery cells.

[0082] Specifically, a guide rail extending in the up-down direction Z is provided on the camera seat support frame 21, a slider is provided on one side of the camera fixing seat 22, and the slider of the camera fixing seat 22 is inserted into the guide rail of the camera seat support frame 21, so that the camera fixing seat 22 drives the camera group to move back and forth along the up-down direction Z on the camera seat support frame 21. A plurality of through grooves 221 are provided on the camera fixing seat 22, and guide rails extending in the first direction X are provided in the through grooves 221. Sliders are provided at the edges of both sides of the camera fixing member, and the slider of the camera fixing member is inserted into the guide rail of the camera fixing member 22, so that the camera fixing member drives the camera group to move back and forth along the first direction X on the camera fixing seat 22. A guide rail extending in the second direction Y is provided on the camera fixing member, and a slider is provided on the non-working end of the camera, and the slider on the camera is inserted into the guide rail of the camera fixing member, so that the camera can move back and forth along the second direction Y on the camera fixing member. Thus, the shooting position of the camera is adjusted according to the position of the battery cell, so as to ensure that the camera can accurately obtain the graphic parameters of the battery cell. In other examples, the movement mode can also be set according to actual conditions, and no specific restrictions are made here. It should be noted here that the working end lens of the camera is located below the through slot 221, so that multiple cameras do not affect each other when photographing the battery cell to obtain graphic parameters, which helps to improve the accuracy of camera photography.

[0083] Furthermore, the visual positioning device 20 also includes a driving component, which includes a fixed seat driver, a fixed member driver, and a camera driver. The fixed seat driver is electrically connected to the camera fixed seat 22 to drive the camera fixed seat 22 to reciprocate along the up-down direction Z. The fixed member driver is electrically connected to the camera fixed member to drive the camera fixed member to reciprocate along the first direction X. The camera driver is electrically connected to the camera to drive the camera to reciprocate along the second direction Y. Specifically, the fixed seat driver, the fixed member driver, and the camera driver can all include linear motors or hydraulic cylinders, as long as they can provide driving force. The type of actual driving component can be set according to actual needs and is not limited here.

[0084] like Figures 4 to 5As shown, in one example, the camera fixing member includes a middle camera fixing member and an edge camera fixing member, the middle camera fixing member 231 is arranged in the middle area of ​​the camera fixing seat 22, and two edge camera fixing members 232 are arranged on opposite sides of the camera fixing seat 22, and the middle camera fixing member 231 and the edge camera fixing member 232 are both arranged on the camera fixing seat 22 in parallel and movably along the first direction X, thereby driving the camera group to move back and forth along the first direction X, so as to completely and accurately take pictures and record the specific position information of the battery cell. The camera group includes two groups of cameras, one group includes a middle camera 241, and the other group includes an edge camera 242, the middle camera 241 is located in the middle area of ​​the camera fixing seat 22, and is movably connected to the middle camera fixing member 231; the edge camera 242 is located on both sides of the camera fixing seat 22, and is movably connected to the edge camera fixing member 232; wherein, the middle camera 241 and the edge camera 242 can be moved along the second direction Y relative to the camera fixing member, respectively.

[0085] In one example, the middle camera first shoots the middle of the battery cell and records the data, and the edge camera 242 then shoots the four corners of the battery cell and records the data; in another example, the middle camera 241 first shoots the middle of the battery cell and records the data, and the edge camera 242 then shoots the four sides of the battery cell and records the data; in another example, the middle camera 241 first shoots the preliminary graphics of the battery cell and records the data, and the edge camera 242 then shoots the precise graphics of the battery cell and records the data. Through the joint shooting of the middle camera 241 and the edge camera 242, the graphic parameters of the battery cell can be accurately obtained. If the battery cell is a special-shaped battery cell, that is, the projection of a certain side of the battery cell in the vertical direction Z is an irregular line, the graphic parameters of the entire battery cell are first obtained, and then the edge camera 242 is moved to focus on the precise shooting of the irregular side. It should be noted here that the irregular side of the special-shaped battery cell is usually a long side. The camera group transmits the captured battery cell graphics to the control module, and the control module converts the graphic parameters into coordinate values ​​of multiple continuous points and feeds them back to the gluing device, so that the gluing device can accurately apply glue to the battery cell; if the battery cell is an irregular battery cell, the control module needs to fit the points of the irregular side. In a preferred example, the parameters of the points on the irregular side are fitted into a straight line to facilitate the gluing device to process the irregular side.

[0086] In order to realize the gluing process of the battery sheet with acquired graphic parameters, Figure 6As shown, in a specific example that can be implemented, the glue coating device includes a glue coating component 34, a lifting module 35 and a plane module 36; the glue coating component 34 includes a glue coating bracket 341 and a glue coating wheel 342 arranged on the glue coating bracket 341, and the glue coating component 34 is configured to perform glue coating on the battery cell; the glue coating component 34 is arranged on the lifting module 35, and the lifting module 35 is configured to drive the glue coating component 34 to reciprocate along the up and down direction Z, that is, to rise or fall; the lifting module 35 is arranged on the plane module 36, and the plane module 36 is provided. The surface module 36 includes a first direction linear module 361, a second direction linear module 362 and a fixed seat 363. The first direction linear module 361 is arranged on the second direction linear module 362, and the second direction linear module 362 is arranged on the fixed seat 363. In the working state, the plane module 36 is configured to drive the glue coating component 34 to reciprocate along the first direction X, or drive the glue coating component 34 to reciprocate along the second direction Y, or drive the glue coating component 34 to reciprocate along the first direction X and the second direction Y at the same time.

[0087] Specifically, the glue coating wheel 342 is fixedly arranged on the glue coating bracket 341, and a slider is arranged on the side of the glue coating bracket 341 away from the glue coating wheel 342; the lifting module 35 includes a lifting guide rail and a lifting drive component, the lifting guide rail is a guide rail extending along the up-down direction Z, the slider on the glue coating bracket 341 is inserted into the lifting guide rail, and the lifting drive component drives the glue coating component 34 to move back and forth in the up-down direction Z in the lifting guide rail, so that the glue coating wheel 342 can rise or fall in the up-down direction Z, and a slider is arranged at the bottom end of the lifting guide rail; the first side The first linear module 361 includes a first linear guide and a linear drive assembly, the slider of the lifting guide is inserted in the first linear guide, the linear drive assembly drives the lifting module 35 to reciprocate along the first direction X in the first linear guide, and a slider is provided at the bottom end of the first linear guide; the second linear module 362 includes a second linear guide and a linear drive assembly, the slider of the first linear guide is inserted in the second linear guide, and the linear drive assembly drives the first linear module 361 to reciprocate along the second direction Y in the second linear guide.

In actual applications, after fitting the points on the irregular side of the irregular battery cell, it is a straight line. During the gluing process, it is sufficient to perform position coordinate compensation in the first direction X or the second direction Y.

[0088] like Figure 2As shown, in a specific embodiment, the gluing device includes a first sub-gluing device 31, a second sub-gluing device 32 and a third sub-gluing device 33. The structure of each sub-gluing device is the same as the specific structure of the above-mentioned gluing device. The first sub-gluing device 31 is correspondingly provided with a first sub-gluing station, and the first sub-gluing device 31 is configured to perform gluing on the relatively long side of the battery cell; the second sub-gluing device 32 is correspondingly provided with a second sub-gluing station, and the second sub-gluing device 32 is configured to perform gluing on the relatively short side of the battery cell; the third sub-gluing device 33 is correspondingly provided with a third sub-gluing station, and the third sub-gluing device 33 is configured to perform gluing on the chamfer of the battery cell.

When the third sub-glue coating device 33 is provided with two, each third sub-glue coating device 33 performs glue coating on two chamfers of the cell, and when the third sub-glue coating device 33 is provided with four, each third sub-glue coating device 33 performs glue coating on one chamfer of the cell. Each time the cell passes through a sub-glue coating station, it needs to rotate a preset angle to perform glue coating on different sides or chamfers.

[0089] In order to realize the transmission of battery cells in different workstations, such as Figure 7 As shown, in a specific example that can be implemented, the transmission device 40 includes a transmission carrier platform 41 and a first rotating device 42. The transmission carrier platform 41 is configured to carry battery cells. A plurality of adsorption holes are provided on the transmission carrier platform 41. The plurality of adsorption holes are interconnected. The adsorption holes are also connected to a vacuum generator. The vacuum generator is configured to adsorb the battery cells through the adsorption holes. The first rotating device 42 is located below the transmission carrier platform 41. The first rotating device 42 is configured to drive the transmission carrier platform 41 to rotate along the up and down direction Z.

[0090] like Figure 1As shown, in one example, the transmission device 40 is a linear transmission structure, specifically including a linear plate chain structure or a linear belt structure, the plate chain structure or the belt structure moves in a circular motion up and down, and the transmission carrier 41 is arranged in sequence along the transmission direction of the battery cell, and the transmission device 40 is sequentially provided with a visual positioning station, a first sub-gluing station, a second sub-gluing station, and a third sub-gluing station, and the visual positioning station is correspondingly provided with a visual positioning device 20, and the first sub-gluing station is surrounded by two relatively arranged first sub-gluing devices, the second sub-gluing station is surrounded by two relatively arranged second sub-gluing devices, and the third sub-gluing station is surrounded by two relatively arranged third sub-gluing devices, and each station is correspondingly provided with a transmission carrier 41, and a first rotating device 42 is provided below the transmission carrier 41.

[0091] The specific working process of the battery cell gluing equipment in this example is as follows: the battery cell to be glued carried by the transmission carrier 41 obtains the graphic parameters of the battery cell through the visual positioning device 20 at the visual positioning station, and then is transmitted to the first sub-gluing station. The first sub-gluing device 31 performs glue processing on the two relatively long sides of the battery cell. When one of the long sides is an irregular side, the plane module 36 of the gluing device directly compensates the position of the irregular side during the gluing process, and then is transmitted to the second sub-gluing station. The battery cell is rotated 90° by the first rotating device 42. The second sub-gluing device 32 performs glue processing on the two relatively short sides of the battery cell, and then is transmitted to the third sub-gluing station. The battery cell is rotated by a preset angle by the first rotating device 42. The third sub-gluing device 33 performs glue processing on the two relative chamfers of the battery cell. Then the battery cell is rotated in the opposite direction by a preset angle by the first rotating device 42. The third sub-gluing device 33 performs glue processing on the other two relative chamfers of the battery cell, and the gluing process of the battery cell is completed.

[0092] like Figure 2 As shown, in another example, the transmission device 40 also includes a rotating platform device 43, the rotating platform device 43 includes M processing tables, and M processing stations are arranged along the circumference of the rotating platform device 43. One processing table 431 corresponds to one processing station. The processing table 431 is configured to rotate and transfer the battery cells to each processing station. The processing stations at least include a loading station, a visual positioning station and a unloading station in sequence. A second rotating device is arranged on the processing table, and the second rotating device is configured to drive the processing table 431 to rotate around the up and down direction Z, wherein M≥3, and M is an integer. It should be noted here that the unloading station coincides with the first sub-gluing station, and can also be defined as a gluing station. Preferably, the rotating platform device 43 is a cantilever structure, which absorbs the battery cells from above for transmission.

[0093] The specific working process of the battery cell gluing equipment in this example is as follows: the processing table 431 absorbs the battery cell to be glued at the loading station, and is rotated and transferred to the visual positioning station through the rotating platform device 43. The battery cell obtains the graphic parameters of the battery cell through the visual positioning device 20 at the visual positioning station, and then is rotated and transferred to the unloading station. In this process, the battery cell is rotated by the processing table to set the long side edge of the battery cell parallel to the transmission and gluing direction of the battery cell. The unloading station coincides with the first sub-gluing station in the up-down direction Z. The transmission carrier 41 on the first sub-gluing station receives the battery cell that has obtained the graphic parameters, and the first sub-gluing device 31 glues the two relatively long sides of the battery cell. Glue treatment, when a long side is an irregular side, the planar module 36 of the glue coating device directly compensates the position of the battery cell during the glue coating process, and then it is transmitted to the second sub-glue coating station, the battery cell is rotated 90° by the first rotating device 42, and the second sub-glue coating device 32 performs glue coating on the two relatively short sides of the battery cell, and then it is transmitted to the third sub-glue coating station, the battery cell is rotated by a preset angle by the first rotating device 42, and the third sub-glue coating device 33 performs glue coating on the two relative chamfers of the battery cell, and then the battery cell is rotated in the opposite direction by a preset angle by the first rotating device 42, and the third sub-glue coating device 33 performs glue coating on the two outer relative chamfers of the battery cell, thereby completing the glue coating process on the battery cell.

Specifically, the gluing device is arranged beside the transmission device 40, and after the battery cell is glued, the applied glue is immediately cured. The curing treatment methods include light curing and thermal curing; when the curing device 50 is a laser curing lamp, the laser curing lamp emits light, and the light is irradiated on the glue, and the glue can be cured; when the curing device 50 is a heating lamp, the heat emitted by the light can cure the glue. The curing device 50 can also be a hot air generator, which also provides heat to cure the glue. An exhaust device is also required here to discharge the excess heat generated by the heating lamp to avoid the influence of excessive temperature on the battery cell.

[0096] Specifically, the loading device 60 includes a loading channel 61, which is configured to transport the battery cells to be coated with glue along the first direction X. The battery cells to be coated with glue need to be cleaned and corrected before loading. The loading device 60 also includes a blowing device and a correcting device. The blowing device is arranged above the loading channel 61, and the blowing device is configured to blow away foreign matter on the battery cells to be coated with glue on the loading channel 61. The correcting device is arranged on the side of the loading channel 61, and the correcting device is configured to correct the position of the battery cells to be coated with glue on the loading channel 61 to ensure that the position of the battery cells to be coated with glue does not deviate greatly during loading.

[0097] When the transmission device 40 is only a linear transmission device, the battery cell can be transported from the loading device 60 to the visual positioning station by a manipulator or other means, and the specific setting can also be made according to the actual situation, and no limitation is made here. When the transmission device 40 also includes a rotating platform device 43, the processing stations include a loading station, a visual positioning station and a gluing station in sequence. The processing table where the loading station is located is located above the loading device 60, and the battery cell to be glued can be directly adsorbed from above the loading device 60.

In this example, the unloading device 70 is located downstream of the curing device 50, and the unloading device 70 is configured to unload the battery cell that has completed the glue coating process. Specifically, the unloading device 70 includes a conveying device and a unloading flow channel 71, and the unloading flow channel 71 is configured to transport the battery cell that has completed the glue coating process along the first direction X. The conveying mechanism transports the battery cell that has completed the glue coating process on the conveying device 40 to the unloading flow channel 71 to complete the unloading of the battery cell.
