[0030] Solar cells can convert clean light energy into electrical energy, offering the advantages of high efficiency, low attenuation, and strong reliability, and are therefore widely applicable. A solar cell primarily comprises a cell 10 and a cell backsheet 20. Conventional solar cell packaging relies primarily on manual bonding of the cell 10 to the cell backsheet 20, which has been coated with butyl tape 201 and POE film 202. However, manual bonding can result in deviations, which can affect the performance and aesthetics of the solar cell, reducing the quality of the packaging.

[0031] For this reason, Figure 1 and Figure 2 As shown, this embodiment provides a packaging device, including an upper cover 1 and a base 2 that can be snapped together. The upper cover 1 is provided with an upper limit groove 11 for accommodating a battery cell 10. The size of the upper limit groove 11 matches the size of the battery cell 10. The base 2 is provided with a lower limit groove 21 for accommodating a battery back plate 20 at a position corresponding to the upper limit groove 11. The length of the upper limit groove 11 in the vertical direction is consistent with the length of the lower limit groove 21 in the front-to-back direction. The length of the upper limit groove 11 in the left-to-right direction is less than the length of the lower limit groove 21 in the left-to-right direction. When the upper cover 1 is snapped onto the base 2, the upper limit groove 11 is located in the middle of the lower limit groove 21. The packaging device also includes an upper clamping assembly 3 and a lower clamping assembly 4. The upper clamping assembly 3 is provided on the upper cover 1 and is used to clamp the battery cell 10 on the upper and lower sides. The lower clamping assembly 4 is provided on the base 2 and is used to clamp the battery back plate 20 on the left and right sides in the middle of the lower limit groove 21.

[0032] The packaging device provided by this embodiment, when in use, places the battery cell 10 in the upper limit groove 11, and clamps the side of the battery cell 10 through the upper clamping component 3 to prevent the battery cell 10 from falling out of the upper limit groove 11 when the upper cover 1 is buckled. Then, the battery back plate 20 with the butyl tape 201 and the POE film 202 is placed in the lower limit groove 21, and the side of the battery back plate 20 is clamped by the lower clamping component 4, and the battery back plate 20 is clamped in the middle position of the lower limit groove 21. At this time, the battery cell 10 and the battery back plate 20 are aligned, and then the upper cover 1 is buckled on the base 2 to make the battery cell 10 and the battery back plate 20 fit together. Finally, the upper clamping component 3 and the lower clamping component 4 are released from the clamping state, the upper cover 1 is opened, and the bonded battery cell 10 and battery back plate 20 are taken out and placed in a laminator for lamination. The packaging equipment is easy to operate, can ensure the fitting accuracy of the battery cell 10 and the battery back plate 20, improve the packaging quality of the solar cell, and solve the influence of human factors on the packaging quality.

[0033] In this embodiment, one side of the upper cover 1 is hinged to the base 2. Specifically, the upper cover 1 can be hinged to the base 2 via a hinge, a rotating shaft, or other structure. This hinged connection facilitates the opening and closing of the upper cover 1, making it quick and easy to operate, saving time and effort, and eliminating the need to move the upper cover 1.

[0034] Furthermore, if Figure 1 As shown, the upper clamping assembly 3 includes two clamping parts 31 symmetrically arranged on opposite sides of the upper limit groove 11, the clamping parts 31 include a screw 311, a connecting piece 312 and an abutment 313, a screw hole is opened in the upper cover 1, the screw 311 is threadedly connected to the screw hole, and the head end of the screw 311 extends out of the screw hole for the operator to screw it, the connecting piece 312 is movably connected to the end of the screw 311 and is slidably arranged in the upper cover 1, the abutment 313 is fixedly connected to the side of the connecting piece 312 away from the screw 311, the abutment 313 can extend into the upper limit groove 11 and abut against the side of the battery cell 10, and the upper cover 1 is provided with holes for the connecting piece 312 and the abutment 313 to slide. By screwing the screw 311, the screw 311 moves along the screw hole, and the screw 311 drives the connecting piece 312 to slide in the hole inside the upper cover 1. The connecting piece 312 drives the abutting piece 313 to slide in the hole inside the upper cover 1, and finally the abutting piece 313 partially extends into the upper limit slot 11 and abuts the side of the battery cell 10. During operation, the two screws 311 can be screwed simultaneously to move the abutting pieces 313 on the upper and lower sides of the battery cell 10 toward the battery cell 10 at the same time, and simultaneously clamp the upper and lower sides of the battery cell 10, thereby preventing the battery cell 10 from falling out of the upper limit slot 11 when the upper cover 1 is buckled.

[0035] Specifically, to achieve a movable connection between connector 312 and screw 311, in an optional embodiment, a stopper plate having an outer diameter larger than that of screw 311 can be provided at the end of screw 311. An inverted T-shaped hole can be provided on the side of connector 312 near screw 311. The stopper plate engages with the wider portion of the inverted T-shaped hole, while screw 311 engages with the smaller portion of the inverted T-shaped hole. In this way, screw 311 can be rotatably connected to connector 312. When screw 311 rotates relative to connector 312, it can also drive connector 312 to move, and the two cannot separate.

[0036] In this embodiment, Figure 1 As shown, each clamping component 31 includes two spaced-apart abutting members 313, which together abut against the side of the battery cell 10. This arrangement ensures that each clamping component 31 contacts the battery cell 10 at two points, ensuring that the force applied to the battery cell 10 is uniform and stable, thereby ensuring that the battery cell 10 can be stably clamped. In other embodiments, each clamping component 31 may also include three, four, or more spaced-apart abutting members 313, which can be flexibly arranged according to actual needs and is not specifically limited here.

[0037] Further, combined with Figure 1 and Figure 2 The lower clamping assembly 4 includes a lead screw 41, a slider 42, a connecting rod 43, and a push plate 44. A through hole 22 extending in the left-right direction is defined within the base 2. The two ends of the lead screw 41 are rotatably mounted within the through hole 22. The lead screw 41 includes two threaded portions 411 rotating in opposite directions. A slider 42 is threadedly connected to each threaded portion 411. Each slider 42 is provided with a connecting rod 43. Each connecting rod 43 passes through the base 2 and is connected to a corresponding push plate 44. The push plates 44 slide within the lower limit slot 21 and are positioned on the left and right sides of the battery back plate 20 to clamp the battery back plate 20. The two sliders 42 are symmetrically positioned about the center of the lead screw 41. By rotating the lead screw 41, the two sliders 42 can be synchronously moved toward or away from each other. A groove is provided at the bottom of the base 2, and the slider 42 is hidden in the groove. The two ends of the screw 41 can be rotatably arranged in the through holes 22 on both sides through bearings. The threaded portion 411 of the screw 41 is located in the middle position of the screw 41 and is exposed in the groove to cooperate with the slider 42.

[0038] When the battery back plate 20 needs to be clamped, the lead screw 41 is rotated in a certain direction. At this time, the two sliders 42 move synchronously toward each other. Each slider 42 drives the connecting rod 43 and the push plate 44 located on the left and right sides of the battery back plate 20 to move toward each other. The push plate 44 slides in the lower limit groove 21, thereby clamping the left and right sides of the battery back plate 20 and clamping it in the middle position of the lower limit groove 21 to align with the battery cell 10, ensuring the fitting accuracy of the battery cell 10 and the battery back plate 20. In this process, even if the battery back plate 20 is not aligned with the battery cell 10 when it is just placed in the lower limit groove 21, the pushing action of the push plates 44 on both sides can push the battery back plate 20 to the middle position of the lower limit groove 21, and the positioning effect is good. After the battery cell 10 and the battery back plate 20 are bonded together, the screw 41 is rotated in the opposite direction. At this time, the two sliders 42 move synchronously in the direction away from each other. Each slider 42 drives the connecting rod 43 and the push plate 44 on the left and right sides of the battery back plate 20 to move in the direction away from each other, thereby releasing the clamping effect on the battery back plate 20, so that the bonded battery cell 10 and battery back plate 20 can be removed.

[0039] like Figure 2 As shown, one end of the lead screw 41 is connected to a rocker 412, and the rocker 412 extends to the outside of the base 2. This arrangement makes it convenient for the operator to rotate the lead screw through the rocker 412 for adjustment.

[0040] In this embodiment, if Figure 2 As shown, each slider 42 is provided with at least two connecting rods 43 spaced apart along the front-to-back direction, and each connecting rod 43 is connected to a push plate 44. With this arrangement, two push plates 44 abut against the left and right sides of the battery back plate 20, providing a sufficient contact area. This ensures that the battery back plate 20 is subjected to uniform and stable force, preventing the battery back plate 20 from deflecting during the pushing process, thereby achieving the purpose of accurately positioning the battery back plate 20. In other embodiments, each slider 42 may be provided with three, four, or more connecting rods 43 spaced apart along the front-to-back direction, each connecting rod 43 being connected to a push plate 44. This arrangement can be flexibly configured according to actual needs and is not specifically limited here.

[0041] Furthermore, if Figure 2As shown, the lower clamping assembly 4 also includes two load-bearing rods 45, which are respectively located on the front and rear sides of the lead screw 41. A connecting hole 24 extending in the left and right direction is also opened in the base 2. The two ends of the load-bearing rod 45 are fixed in the connecting hole 24. The two ends of the load-bearing rod 45 can be fixed in the connecting hole 24 by interference fit, threaded connection, welding, clamping, etc. The opposite ends of the load-bearing rod 45 are respectively passed through the corresponding slider 42 and slidably cooperate with the slider 42. When the two sliders 42 move synchronously, they slide along the load-bearing rod 45. The load-bearing rod 45 plays the role of supporting the slider 42, sharing the bearing force of the lead screw 41, avoiding that all the load is applied to the lead screw 41, and extending the service life of the lead screw 41.

[0042] In an optional embodiment, if Figure 1 As shown, a take-out slot 25 is further provided on the side wall of the lower limit slot 21. After the battery cell 10 and the battery back plate 20 are attached, the operator can remove the attached battery cell 10 and the battery back plate 20 through the take-out slot 25 after opening the upper cover 1, which is convenient for operation.

[0043] Furthermore, the bottom of the lower limit slot 21 is provided with a strip-shaped hole 23 for the connecting rod 43 to pass through. The strip-shaped hole 23 extends in the left-right direction. When the slider 42 drives the connecting rod 43 and the push plate 44 to move left and right, the connecting rod 43 can move left and right within the strip-shaped hole 23 without interference, thereby allowing the push plate 44 to move left and right. The lower limit slot 21 extends left and right through the base 2 to prevent interference with the push plate 44 during movement.

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
