Description

Technical Field

[0001] The utility model relates to the technical field of solar cell transmission, in particular to a solar cell transmission device and solar cell manufacturing equipment. Background Art

[0002] In the solar energy manufacturing process, in order to increase production capacity, the number of tracks for transporting silicon wafers in the transmission equipment is often increased to transport multiple silicon wafers at the same time. Since the transmission structure of the transmission equipment is mainly a plurality of transmission rollers, the increase in the number of tracks will inevitably require an increase in the length of the transmission rollers to accommodate the simultaneous transmission of multiple silicon wafers.

[0003] At present, when the length of the transmission roller is too long, under the influence of the overall gravity of the transmission roller, the middle part of the transmission roller sags more. The sag increases the acceleration of the silicon wafers during the transportation of the silicon wafers, making the transmission speed of the silicon wafers in the middle part greater than the transmission speed of the two side parts, thereby causing the silicon wafers output from the middle track to lead the silicon wafers output from the two side tracks, that is, the silicon wafers output from the multiple tracks are not aligned; and a retractable board machine is often provided at the output end of the transmission equipment to receive silicon wafers. The uneven silicon wafers output from the multiple tracks will further cause the retractable board machine to be unable to receive the silicon wafers normally, causing damage or shutdown problems during the battery cell manufacturing process.

[0004] Therefore, there is an urgent need for a battery cell transmission device and a battery cell manufacturing equipment to solve the above technical problems. Utility Model Content

[0042] Embodiment 1

[0043] This embodiment provides a battery cell transmission device, which is used for transmitting the battery cell 200 .

[0044] It should be noted that Figure 1 The X direction is the material conveying direction.

[0045] Please refer to Figure 1 and Figure 2Specifically, the battery cell transmission device includes a fixed frame and a plurality of transmission rollers 10 arranged on the fixed frame, the plurality of transmission rollers 10 are arranged at intervals along the material conveying direction to form a material conveying path for conveying the battery cells 200; at least one transmission roller 10 is formed as an adjustment roller 30, the outer diameters of both ends of the adjustment roller 30 are larger than the outer diameter of the middle part of the adjustment roller 30, so as to adjust the relative positions of the battery cells 200 of the same batch on the material conveying path.

[0046] The battery cell transmission device in this embodiment forms at least one transmission roller 10 into an adjustment roller 30, and increases the outer diameter of the two ends of the adjustment roller 30 so that the outer diameter of the two ends of the adjustment roller 30 is greater than the outer diameter of the middle portion of the adjustment roller 30, thereby compensating for the transmission distance of the battery cell 200 in the middle position exceeding the battery cells 200 at the two end positions due to the sagging of the middle of the transmission roller 10. It can ensure that when the length of the transmission roller 10 is increased, the battery cells 200 fed in at the same time can be kept neat when output, so as to facilitate subsequent operations.

[0047] Specifically, in the present embodiment, along the material conveying direction, the material conveying path is divided into a feed section 1, a middle section 2 and a discharge section 3; among the multiple conveying rollers 10 located in the feed section 1, the conveying rollers 10 away from the feed side are formed as adjusting rollers 30, so that the material can be adjusted after entering the battery cell conveying device for a period of time, so that it can better enter the next process; among the multiple conveying rollers 10 located in the discharge section 3, the conveying rollers 10 close to the discharge side are formed as adjusting rollers 30, which ensures that each battery cell 200 remains neat when the material is conveyed out, thereby improving the reliability of the operation of the battery cell conveying device.

[0048] Optionally, in this embodiment, the middle section 2 may only include a conveying structure for conveying the battery cells 200 ; it may also be a process section with a transfer roller 10 , which is not specifically limited here.

[0049] Specifically, the conveying structure located in the middle section 2 is a transmission roller 10 , that is, the transmission roller 10 in the middle section 2 is only used to convey the battery cells 200 .

[0050] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the transmission roller 10 includes a roller shaft 11 and a plurality of rollers 12 sleeved on the roller shaft 11; when the transmission roller 10 is formed into an adjusting roller 30, at least the outer diameter of the rollers 12 located at both ends of the adjusting roller 30 is greater than the outer diameter of the roller 12 located in the middle of the adjusting roller 30, so that the circumference of the rollers 12 located at both ends of the adjusting roller 30 is greater than the circumference of the roller 12 in the middle, so that the conveying speed of the battery cells 200 located at both ends of the adjusting roller 30 is increased to catch up with the battery cells 200 located in the middle of the adjusting roller 30, so as to achieve the adjustment of the relative positions of each battery cell 200.

[0051] Optionally, the outer circumference of the roller 12 is provided with a spiral structure, a sawtooth structure or a plurality of triangular protrusions to ensure the driving effect of the roller 12 on the battery cell 200 and avoid the battery cell 200 slipping on the roller 12 of the optical axis.

[0052] In some embodiments, the roller 12 of the adjusting roller 30 is a roller with a constant diameter or a roller with a variable diameter, both of which can achieve the position adjustment function of the adjusting roller 30 .

[0053] Specifically, the rollers 12 of the adjusting roller 30 are rollers of equal diameter, and at least the outer diameters of the rollers 12 at both ends of the adjusting roller 30 are larger than the outer diameter of the roller 12 located in the middle of the adjusting roller 30 , so as to achieve the position adjustment function of the adjusting roller 30 on the battery cell 200 .

[0054] like Figure 2 As shown, optionally, the outer diameters of the rollers 12 at both ends of the adjusting roller 30 are D1 and D3 respectively, and the outer diameter of the roller 12 in the middle of the adjusting roller 30 is D2, D1>D2, D3>D2; according to process requirements, confirm that D1=D3 or D1≠D3 to realize the adjusting function of the adjusting roller 30.

[0055] It should be noted that the outer diameters of the rollers 12 at both ends of the specific adjusting roller 30 need to be designed and adjusted according to the position error of the battery cell 200 during actual transportation and the sagging amount of the adjusting roller 30 itself, and are not specifically limited here.

[0056] Optionally, the outer diameters of the plurality of rollers 12 decrease successively from the end to the middle of the adjustment roller 30, so as to better compensate for the sagging of the transmission roller 10 when transmitting the battery cell 200, so as to adjust the transmission distance of the battery cell 200 on the conveying track corresponding to each roller 12, and better ensure that the battery cells 200 input at the same time remain neat when output.

[0057] Specifically, from the end to the middle of the adjusting roller 30, the outer diameters of the multiple rollers 12 on the adjusting roller 30 are equidistant or variable in pitch, that is, the size of the outer diameters of the rollers 12 of the adjusting roller 30 needs to be set according to actual needs to better match the corresponding transmission roller 10.

[0058] Please refer to Figure 3 More specifically, the radius difference of the outer diameter between two adjacent rollers 12 is L. Along the direction from the end of the transmission roller 10 toward the middle part, the radius difference of the outer diameter between the first group of two adjacent rollers 12 is L1, the radius difference of the outer diameter between the second group of two adjacent rollers 12 is L2, and the outer diameter difference between the two adjacent rollers 12 in the middle is LN, L1=L2…=LN, or L1≠L2…≠LN.

[0059] Exemplarily, in this embodiment, L1=L2 . . . =LN, that is, along the direction from the end of the conveying roller 10 toward the middle part, the outer diameter of each roller 12 decreases equidistantly to fit the droop curve of the actual conveying roller 10 .

[0060] Specifically, at least the rollers 12 at both ends of the adjusting roller 30 are variable diameter rollers, and the outer diameter of the end of the variable diameter roller close to the adjusting roller 30 is larger than the outer diameter of the middle of the variable diameter roller close to the adjusting roller 30. This allows the outer diameter of the rollers 12 at both ends of the adjusting roller 30 to increase smoothly from its middle part, thereby better compensating for the sagging of the conveying roller 10 when conveying the battery cells 200, and further ensuring that the battery cells 200 input at the same time remain neat when output.

[0061] Please refer to Figure 1 In some embodiments, a roller 12 or multiple adjacent rollers 12 form a conveying track, and limit rings 13 are provided at both ends of the conveying track to separate adjacent conveying tracks. Specifically, limit rings 13 are provided at both ends of each roller 12, and the limit rings 13 are used to limit the battery cell 200, so that each roller 12 can transport a battery cell 200, and multiple rollers 12 mounted on the same roller shaft 11 form multiple conveying tracks. When multiple adjacent rollers 12 form a conveying track, the limit rings 13 are set between adjacent conveying tracks to separate adjacent conveying tracks and limit the battery cells 200 on the conveying tracks.

[0062] Specifically, the outer diameter of the limiting ring 13 is greater than the outer diameter of the roller 12 , so that the limiting ring 13 can protrude from the roller 12 to achieve a limiting effect on the battery cell 200 .

[0063] In some embodiments, along the axis direction of the transmission roller 10, the thickness of the limiting rings 13 at both ends of the transmission roller 10 is less than the thickness of the limiting ring 13 located between the two rollers 12. The purpose of this arrangement is to make the thickness of the limiting ring 13 between the two rollers 12 on each transmission roller 10 thicker, so as to increase the spacing between the two rollers 12, so that the conveying tracks corresponding to each roller 12 are independent of each other, and avoid the battery cells 200 of adjacent conveying tracks from offsetting and causing collision.

[0064] Please refer to Figure 4In this embodiment, the battery cell transmission device also includes a plurality of pressure rollers 20. Along the material conveying direction, the plurality of pressure rollers 20 are arranged in sequence and at intervals, and the pressure rollers 20 are arranged above the transmission rollers 10 located in the middle to regularize the battery cells 200 and prevent the battery cells 200 from warping or getting stuck. In addition, the battery cells 200 are light in weight and are prone to slipping when being transmitted by the transmission rollers 10 alone. In the process of the transmission rollers 10 transmitting the battery cells 200, the pressure rollers 20 press against the battery cells 200, thereby increasing the friction between the battery cells 200 and the transmission rollers 10 and reducing the risk of the battery cells 200 slipping.

[0065] Specifically, the pressing roller 20 includes a pressing shaft 21 and a plurality of pressing wheels 22 sleeved on the pressing shaft 21 . The pressing wheels 22 are arranged one-to-one with the rollers 12 , so that on each conveying track, the battery cells 200 pass between the pressing wheels 22 and the rollers 12 to achieve regularization of the battery cells 200 .

[0066] In some embodiments, the gap between the pressing roller 20 and the transfer roller 10 is greater than the thickness of the battery cell 200 , so that the pressing roller 20 does not interfere with the conveyance of the battery cell 200 , thereby avoiding the problem of the pressing roller 20 damaging the battery cell 200 .

[0067] In some embodiments, the gap between the pressure roller 20 and the transfer roller 10 is smaller than the thickness of the battery cell 200, and a protective layer is provided on the surface of at least one of the pressure roller 20 and the transfer roller 10, so as to ensure the friction of the transfer roller 10 on the battery cell 200 while avoiding the problem of the transfer roller 10 and the pressure roller 20 squeezing the battery cell 200 and causing damage to it.

[0068] The present embodiment also provides a battery cell manufacturing equipment, which includes the battery cell transmission device described in any of the above schemes. Through the setting of the above-mentioned battery cell transmission device, multiple battery cells 200 can be transported at the same time, and the transportation of each battery cell 200 will not be affected by the excessive sagging of the transmission roller 10, thereby improving the reliability of the battery cell manufacturing equipment, reducing the fragmentation rate, and improving the manufacturing efficiency.

[0069] It should be noted that the battery cell manufacturing equipment can be a single device or all-in-one equipment such as texturing equipment, PSG removal equipment, BSG removal equipment, alkali polishing equipment, cleaning equipment, developing equipment, electroplating equipment, drying equipment, etc.; the battery cell manufacturing equipment can also be a switching equipment for transmitting battery cells 200 between single devices such as texturing equipment, PSG removal equipment, BSG removal equipment, alkali polishing equipment, cleaning equipment, developing equipment, electroplating equipment, drying equipment, etc., which is not specifically limited here.

[0070] Embodiment 2

[0071] This embodiment provides a battery cell transmission device and a battery cell manufacturing device. The difference between this embodiment and the first embodiment lies in the number and position of the adjustment rollers 30 of the discharge section 3.

[0072] Please refer to Figure 5 In the present embodiment, part of the multiple conveying rollers 10 located in the discharge section 3 is formed as an adjustable roller 30. This arrangement allows the battery cell conveying device to adjust the position of the battery cell 200 more smoothly, so that multiple adjustments can be made when the battery cell 200 is discharged, so that the battery cells 200 finally output are kept neat, and the adjustment range of the adjusting roller 30 is not large each time, avoiding the problem of each battery cell 200 falling off the conveying track due to a large single adjustment range when only a single adjusting roller 30 is set, and at the same time avoiding the single adjustment when only a single adjusting roller 30 is set. The opportunity for supplementary adjustment is avoided.

[0073] Optionally, when some of the multiple conveying rollers 10 located in the discharge section 3 are formed as adjusting rollers 30, the conveying rollers 10 and the adjusting rollers 30 are alternately arranged, that is, the position of each battery cell 200 is adjusted by multi-point distribution, and the position of each battery cell 200 is adjusted more smoothly, thereby reducing the risk of the battery cell 200 falling off the conveying track due to excessive adjustment. When the upstream adjusting roller 30 is not adjusted into place, the downstream adjusting roller 30 can make supplementary adjustments in time, thereby improving the reliability of the battery cell transmission device.

[0074] Embodiment 3

[0075] This embodiment provides a battery cell transmission device and a battery cell manufacturing equipment. The difference between this embodiment and the first and second embodiments is that the transmission rollers 10 of the middle section 2 are arranged differently.

[0076] Please refer to Figure 6 In the present embodiment, part of the multiple transmission rollers 10 located in the middle section 2 is formed as an adjustment roller 30, that is, the middle section 2 of the battery cell transmission device is also provided with an adjustment roller 30, so that the position of the battery cell 200 is continuously adjusted during the entire transmission process, so that there will be no interference and other problems between each batch of battery cells 200, thereby improving the reliability of the battery cell transmission device.

[0077] Optionally, when some of the multiple transmission rollers 10 located in the middle section 2 are formed as adjustment rollers 30, the transmission rollers 10 and the adjustment rollers 30 are alternately arranged, that is, the position of each battery cell 200 is adjusted through multi-point distribution, and the position of each battery cell 200 is adjusted more smoothly, and the problem of falling off the conveying track due to excessive position adjustment will not occur, thereby improving the reliability of the battery cell transmission device.

[0078] It should be noted that the third embodiment can be improved in combination with the first embodiment or the second embodiment.

[0079] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
