[0042] With the development of industry, the new energy industry has flourished, and solar energy technology has also flourished. Focusing on the production of solar silicon wafers in the photovoltaic industry, some process steps currently still rely on manual labor to complete. As labor costs continue to rise, production costs and quality losses also increase.

[0043] After the solar cells are bagged, the open ends of the bags need to be folded. This is currently a manual process that relies on manual labor, resulting in high repetitiveness and low efficiency.

[0044] In order to solve the above problems, the present invention provides a folding device and a battery cell packaging device. Figure 1 A three-dimensional schematic diagram of an embodiment of a folding device provided by the present invention; Figure 2 for Figure 1 A three-dimensional schematic diagram of the hemming assembly in FIG. Figure 3 for Figure 1 A three-dimensional schematic diagram of the flattening component in FIG.

[0045] See also Figures 1 to 5 The folding device 100 includes a folding platform 10 and a folding assembly 20. The folding platform 10 is provided with a bag placement area 11 for placing a bag filled with material; the folding assembly 20 includes a clamping portion 21 for clamping the open end of the bag. The clamping portion 21 has a rotation stroke of rotating up and down relative to the bag placement area 11, and a movable stroke in the direction of approaching and moving away from the bag placement area 11, so that the clamping portion 21 can clamp the open end of the bag for folding.

[0046] In the technical solution provided by the present invention, by setting a folding platform 10 and a folding assembly 20, the material bag is placed on the material bag placement area 11 on the folding platform 10, and the opening end of the material bag can be clamped and folded through the movable stroke of the clamping part 21 of the folding assembly 20, thereby completing the folding process of the opening end of the material bag. Compared with the manual folding solution, it is more efficient, not affected by human factors, and has higher stability.

[0047] It should be noted that the specific implementation form of the clamping portion 21 is not limited, and can be in the form of a clamping claw 26, a robot arm, or a combination of two clamping plates, which is not limited here.

[0048] When the clamping portion 21 moves close to the material bag placement area 11 and moves to the open end of the material bag, the clamping portion 21 clamps the open end of the material bag, then flips upward and moves toward the part of the material bag containing the material, thereby folding the open end of the material bag to the top of the part of the material bag containing the material, completing the folding process of the material bag.

[0049] Furthermore, the specific implementation form of the movable stroke in the direction of approaching and moving away from the material bag placement area 11 is not limited, and can be a horizontal and vertical movable stroke, or a horizontal and vertical movable stroke, which is not limited here. In this embodiment, the folding assembly 20 also includes a mounting portion 22, and the mounting portion 22 has a longitudinal and vertical movable stroke; the clamping portion 21 is rotatably mounted on the mounting portion 22. In this arrangement, the clamping portion 21 is rotatably mounted on the mounting portion 22, and the clamping portion 21 is driven to reach the material bag placement area 11 through the longitudinal and vertical movable stroke of the mounting portion 22. Then, the clamping portion 21 clamps the open end, moves upward, moves longitudinally toward the material in the material bag, and then flips over, thereby folding the open end of the material bag to the top of the material-containing part of the material bag, completing the folding process of the material bag.

[0050] It is understandable that when the mounting portion 22 has only longitudinal and vertical movable travels, it can only be adapted to the folding process of the material bags placed along the longitudinal direction.

[0051] In order to allow the mounting portion 22 to adapt to more scenarios and not be restricted by the placement position of the bag, the mounting portion 22 also has a lateral movable stroke, so that the folding assembly 20 can be used to fold the bag regardless of whether the bag is placed horizontally or vertically.

[0052] Specifically, the folding assembly 20 also includes a first mounting seat 23, a second mounting seat 24 and a third mounting seat 25. The second mounting seat 24 is movably mounted on the first mounting seat 23 along the longitudinal direction; the third mounting seat 25 is movably mounted on the second mounting seat 24 along the up and down directions; the mounting portion 22 is mounted on the third mounting seat 25. With such an arrangement, when the second mounting seat 24 moves along the longitudinal direction, it drives the second mounting seat 24 and the mounting portion 22 to move longitudinally together, and when the third mounting seat 25 moves along the up and down directions, it drives the mounting portion 22 to move along the up and down directions. By setting the first mounting seat 23, the second mounting seat 24 and the third mounting seat 25, the movement of the mounting portion 22 along the longitudinal direction and the up and down directions can be realized.

[0053] More specifically, the specific implementation form of the second mounting seat 24 being movably mounted on the first mounting seat 23 along the longitudinal direction is not limited. It can be that the first mounting seat 23 is provided with a slide groove extending along the longitudinal direction, and the corresponding second mounting seat 24 is fixedly provided with a slider. Through the cooperation of the slide groove and the slider, the second mounting seat 24 is movably mounted on the first mounting seat 23 along the longitudinal direction. It can also be that the first mounting seat 23 is provided with a slide rail extending along the longitudinal direction, and the second mounting seat 24 is slidably mounted on the slide rail. It can also be a solution using a slide shaft, etc., which is not limited here. Similarly, the third mounting seat 25 is movably mounted on the second mounting seat 24 in the up and down directions, and can also be implemented in the form of a slider, a slide groove, a slide rail, a slide shaft, etc., which is not limited here.

[0054] Furthermore, the movement of the second mounting seat 24 and the third mounting seat 25 may be driven by manpower or by a driving device such as a cylinder, a motor, etc., which is not limited here.

[0055] More specifically, the mounting portion 22 may be movably mounted on the third mounting seat 25 in a transverse direction, so that the mounting portion 22 can be adapted to more scenarios.

[0056] Furthermore, in this embodiment, the clamping portion 21 is provided on the mounting portion 22 and has two clamping jaws 26 spaced apart laterally. The two clamping jaws 26 are used to clamp both sides of the open end of the material bag. By designing the two clamping jaws 26, both sides of the open end of the material bag are clamped at the same time, thereby improving the stability of clamping the open end of the material bag. Moreover, during the clamping process, the open end of the material bag will not be displaced between the clamping jaws 26, thereby avoiding the swinging of part of the open end of the material bag, which may lead to a low yield rate.

[0057] Furthermore, in order to adapt to material bags of different specifications and models, the two clamping jaws 26 can be arranged close to and away from each other in the transverse direction; the material bag placement area 11 has an end placement area corresponding to the open end of the material bag, and the end placement area is provided with a clearance groove on both sides in the transverse direction, so that the two clamping jaws 26 can clamp the material bag from both sides of the material bag. With this arrangement, the spacing between the two clamping jaws 26 is adjustable. On the one hand, it can adapt to the open ends of material bags of different models. On the other hand, the two clamping jaws 26 can be opened and exited from the material bag placement area 11 in the transverse direction, thereby making way for other components. In addition, the end placement area is provided with a clearance groove on both sides in the transverse direction, so that the clamping jaws 26 can extend under the open end of the material bag, avoiding the occurrence of damage to the material bag during the clamping process of the clamping jaws 26 when the open end of the material bag is placed on a plane.

[0058] It should be emphasized that the two clamping jaws 26 can be arranged to move closer to and farther away from each other in the lateral direction. A driving component can be directly arranged in the mounting portion 22 to drive the two clamping jaws 26 to move, so that the mounting portion 22 is stationary in the lateral direction and the two clamping jaws 26 can move in the lateral direction. Of course, a driving component can also be arranged on the third mounting seat 25 to drive the mounting portion 22 to move in the lateral direction, so that the mounting portion 22 and the clamping jaws 26 move together. This is not limited here. In this embodiment, a cylinder is provided on the third mounting seat 25, and the cylinder drive is connected to the mounting portion 22 to drive the mounting portion 22 to move in the lateral direction, thereby driving the two clamping jaws 26 to move closer to and farther away from each other in the lateral direction.

[0059] In order to achieve synchronous rotation of the two clamping jaws 26, thereby avoiding damage to the material bag caused by the asynchronous rotation of the two clamping jaws 26, the folding assembly 20 also includes a rotating shaft 27, a driving member and two transmission assemblies. The rotating shaft 27 is installed on the mounting portion 22 in an up and down direction; the driving member drives the connecting rotating shaft 27 to drive the rotating shaft 27 to rotate; the two transmission assemblies are installed on the mounting portion 22 corresponding to the two clamping jaws 26 respectively, and the transmission assembly is connected to the rotating shaft 27 and the clamping jaws 26 to drive the two clamping jaws 26 to rotate synchronously under the drive of the driving member. With this arrangement, the rotating shaft 27 can be rotated by the drive of the driving member, and then the two clamping jaws 26 can be rotated under the action of the two transmission assemblies. With this arrangement, one driving member is used to drive the two clamping jaws 26 to rotate, and the synchronization is good.

[0060] Specifically, the installation position of the driving member is not restricted, and it only needs to be able to drive the rotating shaft 27 to rotate. It can be installed on the third mounting seat 25, or it can be installed on the mounting portion 22, or even installed on one end of the rotating shaft 27, etc., and is not limited here. In this embodiment, the driving member includes a motor, and the motor is installed on the third mounting seat 25, and the rotating shaft of the motor is connected to the rotating shaft 27 through a synchronous belt, so that when the motor rotates, the rotating shaft 27 is driven to rotate. Of course, in order to improve the transmission efficiency, a synchronous wheel can also be provided at the location where the rotating shaft 27 is connected to the synchronous belt.

[0061] The specific implementation form of the transmission assembly is not limited, and can be a combination of gears and racks, or a combination of gears and racks. In this embodiment, the transmission assembly includes two synchronous pulleys and a synchronous belt connecting the two synchronous pulleys. The two synchronous pulleys include a first synchronous pulley provided on the rotating shaft 27 and a second synchronous pulley provided on the clamping jaw 26. In this arrangement, through the action of the synchronous belt, under the rotation of the rotating shaft 27, the first synchronous pulley rotates, driving the synchronous belt to rotate, and under the action of the synchronous belt, the second synchronous pulley connected to the clamping jaw 26 is driven to rotate, thereby causing the clamping jaw 26 to rotate.

[0062] At the same time, in order to allow the clamping jaw 26 to have a lateral movable stroke and to prevent the first synchronous pulley from limiting the lateral movable stroke of the clamping jaw 26, the first synchronous pulley and the rotating shaft 27 are locked in place, and the first synchronous pulley has a lateral movable stroke. Specifically, the first synchronous pulley may be connected to the rotating shaft 27 via a spline, a sliding groove extending laterally may be provided on the rotating shaft 27, and a slider may be provided on the inner side of the synchronous pulley.

[0063] In addition, before flanging the bag, the open end of the bag needs to be shaped. Specifically, the bag placement area 11 has an end placement area corresponding to the open end of the bag; the folding device 100 also includes a flattening component 30, and the flattening component 30 includes a first pressure plate 31. The first pressure plate 31 has a movable stroke in the direction of approaching and moving away from the end placement area, so that the first pressure plate 31 can flatten the open end of the bag. In this way, by setting the flattening component 30, the first pressure plate 31 moves to the end placement area to press down the open end of the bag. On the one hand, the open end of the bag can be flattened. On the other hand, in the process of flattening by the first pressure plate 31, the open end of the bag can be pre-folded to leave a mark. In the subsequent folding process using the clamping part 21, the open end of the bag can be folded along the mark left by the flattening process of the first pressure plate 31.

[0064] Since in the bagging process, the material is only placed into the material bag and then transferred to the folding station, the surface of the material bag may be not flat enough. At this time, directly folding the material bag will cause the folding to be not neat and the folding effect is not good. Therefore, before folding, the material bag must be shaped first. Specifically, the material bag placement area 11 has an end placement area corresponding to the open end of the material bag, and a material placement area outside the end placement area; the folding device 100 also includes a shaping device, which is used to shape the material bag in the material bag placement area 11, thereby improving the folding effect of the material bag through the shaping device, and avoiding the material bag being not flat after folding, which causes damage to the material during the boxing process.

[0065] Specifically, in this embodiment, the shaping device includes a flattening device and an exhaust component 40. The flattening device is used to blow air toward the end placement area to flatten the material bag. The exhaust component 40 includes a second pressure plate 41. The second pressure plate 41 has a movable stroke in the direction of approaching and moving away from the material placement area, so that the second pressure plate 41 can press the material bag to exhaust. In this way, the flattening device is used to blow air toward the end placement area, thereby blowing gas into the material bag to allow the material bag to expand and unfold. Then, the second pressure plate 41 of the exhaust component 40 is used to press down, thereby exhausting the gas in the material bag and flattening the material bag. Moreover, after exhausting and flattening, the first pressure plate 31 of the above-mentioned flattening component 30 can also be used to flatten and pre-fold the open end of the material bag. Finally, the first pressure plate 31 withdraws from the end placement area, and the clamping part 21 enters the end placement area to clamp the open end of the material bag to complete the folding process.

[0066] In order to prevent the open end from flipping up after folding and maintain the folding state, the folding device 100 also includes a folding holding component 50, and the folding holding component 50 includes a pressure block, which has a movable stroke in the direction of approaching and moving away from the material placement area, so that the pressure block can press the fold in the material placement area, thereby maintaining the folding state through the pressure-maintaining effect of the pressure block.

[0067] The present invention also provides a battery cell packaging device, including the above-mentioned folding device 100. The battery cell packaging device includes all the technical features of the above-mentioned folding device 100, and therefore also has the technical effects brought by all the above-mentioned technical features, which will not be described one by one here.

[0068] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
