Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0026] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0027] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0028] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0029] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0030] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings.

Therefore, the term “above” includes both “above” and “below” orientations depending on the spatial orientation of the device. The device may also be positioned in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relation terms used herein will be interpreted accordingly.

Furthermore, although the examples described herein have a wide variety of constructions, other constructions are possible, as will be apparent upon understanding the disclosure of this application.

[0034] The first aspect of this application provides a PCM bending device, thereby solving the problems of fluctuation deviation and inaccurate positioning that occur during the rotational bending of PCM boards when using a traditional vacuum suction cup clamping method, which leads to bending misalignment and low precision. See below for reference. Figures 1 to 10 This application describes a PCM bending apparatus according to some embodiments. Additionally, for ease of description, the X, Y, and Z directions will be referred to as mutually perpendicular, where perpendicular means 90° ± 5°.

[0035] like Figure 1 and Figure 3 As shown, the PCM bending device of this application includes a clamping and positioning mechanism 100 and a rotary drive mechanism 200. The clamping and positioning mechanism 100 includes a rotating base 110, a positioning base 120, and a positioning push block 130. In the initial state, the positioning base 120 is mounted above the rotating base 110, and the PCM plate 610 is placed above the positioning base 120 along the Y direction. A limiting part 121 is provided on one side of the positioning base 120 in the X direction, and the positioning push block 130 is disposed on the other side of the positioning base 120 in the X direction and is slidably connected to the rotating base 110. The positioning push block 130 can slide along the X direction to clamp or release the PCM plate 610 with the limiting part 121. The rotary drive mechanism 200 is connected to the rotating base 110 to drive the rotating base 110 to rotate the PCM plate 610 around a predetermined axis, which is parallel to the Y direction.

[0036] As described above, the rotary drive mechanism 200 of this application drives the rotary base 110 to rotate the PCM plate 610 around a predetermined axis for rotary bending of the PCM plate 610. Furthermore, during the rotary bending process, the PCM plate 610 is fixedly positioned by the positioning push block 130 sliding along the X direction and clamping it with the limiting part 121. Compared to the vacuum suction method of the prior art, this application fixes the PCM plate 610 by clamping it with the positioning push block 130 and the limiting part 121. During the rotary bending process, the PCM plate 610 will not experience fluctuation deviations or inaccurate positioning, thus preventing bending misalignment.

[0037] Preferably, in the embodiments of this application, such as Figure 3 and Figure 4 As shown, the limiting part 121 is a boss formed on the positioning push block 130, and the PCM plate 610 can be clamped between the boss and the positioning push block 130.

[0038] Furthermore, in the embodiments of this application, such as Figure 5 As shown, the clamping and positioning mechanism 100 of this application may further include a first telescopic cylinder 140 and a telescopic member 150. Multiple positioning push blocks 130 are provided, spaced apart in the Y direction. The first telescopic cylinder 140 is mounted on the rotating base 110. The output end of the first telescopic cylinder 140 passes through the positioning base 120 and connects to the telescopic member 150. The telescopic member 150 is located on one side of the positioning base 120 in the X direction, and the positioning push blocks 130 are located on the other side of the positioning base 120 in the X direction. The telescopic member 150 and the multiple positioning push blocks 130 are fixedly connected via an adapter block 160. Figure 5 Part of the positioning base 120 is hidden in the middle. The adapter block 160 passes through the positioning base 120 to fix the telescopic member 150 and the positioning push block 130 respectively. The output end of the first telescopic cylinder 140 can extend to drive multiple positioning push blocks 130 to simultaneously approach the limiting part 121 so as to clamp the PCM plate 610 with the limiting part 121.

[0039] With this configuration, a first telescopic cylinder 140 (which can be a pneumatic cylinder) can simultaneously drive multiple positioning push blocks 130 (two positioning push blocks 130 are shown in the figure) to move, so as to fix and position each position of the PCM board 610 extending along the Y direction.

[0040] In the embodiments of this application, such as Figure 2As shown, the rotary drive mechanism 200 of this application may include a mounting member 210, a first motor 220 (which may be a servo motor), a driving wheel 230, a driven wheel 240, and a connecting member 250. The first motor 220, the driving wheel 230, and the driven wheel 240 are all mounted on the mounting member 210. The first motor 220 is connected to the driving wheel 230, and the driving wheel 230 and the driven wheel 240 are connected by a transmission connection. The driven wheel 240 is connected to the rotating base 110 via the connecting member 250, thereby driving the rotating base 110 to rotate the PCM plate 610 around the axis of the driven wheel 240.

[0041] Furthermore, in the embodiments of this application, such as Figure 1 and Figure 4 As shown, the PCM bending device also includes a top insert 400 and a carrier 500; the carrier 500 is used to fix the battery 600, which includes a PCM plate 610 and a cell 620. The carrier 500 is used to fix the cell 620, which includes a head and a tab 630 extending from the head. The tab 630 is connected to the PCM plate 610. In the initial state, when the carrier 500 moves the battery 600 to a designated position, the head of the cell 620, the tab 630, and the PCM plate 610 are arranged sequentially along the X direction.

[0042] like Figure 1 and Figure 6 As shown, the top plug 400 is positioned above the carrier 500. The top plug 400 has a reference edge at its head end. The top plug 400 can move so that the reference edge contacts or moves away from the tab 630. When the reference edge of the top plug 400 contacts the tab 630, and the positioning push block 130 and the limiting part 121 clamp the PCM board 610, the rotation drive mechanism 200 can drive the rotation base 110 to rotate the PCM board 610 towards the top plug 400.

[0043] When the reference edge of the top insert 400 contacts the tab 630, and the positioning push block 130 and the limiting part 121 clamp the PCM board 610, the rotary drive mechanism 200 can drive the rotary base 110 to rotate the PCM board 610 towards the top insert 400 until the PCM board 610 reaches the designated position (rotating a first predetermined angle to reach the position of the top insert 400), completing the first bend. At this time, since the reference edge of the top insert 400 contacts the tab 630, the PCM board 610 will bend along the reference edge (the tab 630 will deform, and the crease will be formed along the reference edge, while the PCM board 610 will not deform, but will bend along the reference edge). With this setting, during the rotary bending process, it can not only fix the product in place, but also bend by abutting through the reference edge, thereby ensuring the stable bending of the product.

[0044] After the first bend is completed, the top insert 400 can move away from the tab 630. At this time, the rotary drive mechanism 200 can drive the rotary base 110 to rotate the PCM board 610 towards the head of the cell 620 until the PCM board 610 rotates 180° and flips to the head of the cell 620. It should be noted that since there is already a crease after the first bend, when bending to 180° for the second time, the reference edge of the top insert 400 does not need to contact the tab 630.

[0045] Preferably, in the embodiments of this application, such as Figure 6 and Figure 7 As shown, the top plug-in 400 includes a first plane 410 and a second plane 420. A reference plane is defined on the plane containing the X and Y directions. The angle between the reference plane and the first plane 410 is greater than or equal to a first predetermined angle, which is an obtuse angle. The intersection of the second plane 420 and the first plane 410 forms a reference edge. In the X direction, the first plane 410 faces the PCM board 610, and the second plane 420 faces the battery cell 620. The top plug-in 400 can move linearly along a preset path parallel to the first plane 410, with the reference edge parallel to the Y direction.

[0046] When bending PCM board 610: In the initial state, when the carrier 500 moves the battery 600 to the designated position, the head of the cell 620, the tab 630, and the PCM board 610 are arranged sequentially along the X direction. Then, the reference edge of the top insert 400 contacts the tab 630, and the positioning push block 130 and the limiting part 121 clamp the PCM board 610. Next, the rotation drive mechanism 200 drives the rotation base 110 to rotate the PCM board 610 towards the first plane 410 by a first predetermined angle until the PCM board 610 reaches the designated position (rotating by the first predetermined angle to the position of the first plane 410 of the top insert 400, providing support), completing the first bend. Finally, after the first bend is completed, the top insert 400 moves away from the tab 630. At this time, the rotation drive mechanism 200 can drive the rotation base 110 to continue rotating the PCM board 610 towards the head of the cell 620 until the PCM board 610 rotates 180° and flips over to the head of the cell 620.

[0047] In the embodiments of this application, preferably, the first predetermined angle is an obtuse angle, and the first predetermined angle is 120°. With this setting, the crease will be more stable after the first 120° bend.

[0048] In addition, the second plane 420 of the top plug 400 in this application is an inclined plane, so that when the top plug 400 moves toward the tab 630, the inclined plane will not interfere with the head of the cell 620.

[0049] Preferably, in the embodiments of this application, such as Figure 7 As shown, a chamfered structure is formed at the intersection of the second plane 420 and the first plane 410. The chamfered structure forms a reference edge, which is the edge line of the chamfered structure. The edge line can be set according to requirements. Figure 7 Not shown in the diagram. This design, with its chamfered structure, effectively prevents damage to the tab 630.

[0050] Furthermore, in embodiments of this application, the top insert 400 can be driven by the oblique insertion positioning mechanism 700, specifically, as follows: Figure 1 and Figure 6 As shown, the inclined insertion positioning mechanism 700 is fixed above the carrier 500. The inclined insertion positioning mechanism 700 includes a second telescopic cylinder 710 (which can be a cylinder). The output end of the second telescopic cylinder 710 is connected to the top plug 400 to drive the top plug 400 to move linearly along a preset path parallel to the first plane 410.

[0051] Furthermore, in embodiments of this application, the PCM bending device further includes a clamping mechanism 800. For example... Figure 1 and Figure 6 As shown, the clamping mechanism 800 is fixed above the carrier 500. Both the clamping mechanism 800 and the inclined positioning mechanism 700 are fixed on the bracket 1100. The clamping mechanism 800 includes a third telescopic cylinder (which can be a pneumatic cylinder) 810 and a clamping member 820. The output end of the third telescopic cylinder 810 is connected to the clamping member 820 to drive the clamping member 820 to move along the Z direction.

[0052] like Figure 6 As shown, the carrier 500 includes a fixing member 510, a first guide rail 520, and a support member 530. The battery cell 620 is placed on the support member 530. The first guide rail 520 is connected to the support member 530 and extends along the Z direction. The fixing member 510 is positioned above the battery cell 620 and is slidably connected to the first guide rail 520. The output end of the third telescopic cylinder 810 can extend to press the battery cell 620 against the fixing member 510. With this configuration, when the carrier 500 moves the battery 600 to a designated position, the output end of the third telescopic cylinder 810 can extend to press the battery cell 620 against the fixing member 510, thereby fixing the battery cell 620.

[0053] Furthermore, in the embodiments of this application, such as Figure 1 and Figure 2 As shown, the PCM bending device also includes a Z-axis moving module 300, which includes a Z-axis slider 310 that moves along the Z direction, and a mounting member 210 connected to the Z-axis slider 310. With this configuration, the position of the clamping and positioning mechanism 100 can be finely adjusted in the Z direction via the Z-axis moving module 300.

[0054] Furthermore, in the embodiments of this application, such as Figure 1 As shown, a fine-tuning screw 1110 can also be provided on the bracket 1100 to adjust the position of the bracket 1100 in the X direction, thereby adjusting the position of the inclined insertion positioning mechanism 700 and the clamping mechanism 800.

[0055] Furthermore, in the embodiments of this application, such as Figure 1 As shown, the PCM bending device also includes an X-axis moving module 900. The bottom ends of the Z-axis moving module 300 and the bracket 1100 are both fixed on the X-axis moving module 900. With this configuration, the positions of the clamping positioning mechanism 100, the oblique insertion positioning mechanism 700, and the pressing mechanism 800 can be finely adjusted in the X direction via the X-axis moving module 900.

[0056] As an example, such as Figure 8 As shown, the X-axis moving module 900 includes a second motor 910, a lead screw 920, a nut 930, an X-axis slide 940, and a base 950. The second motor 910 is connected to the lead screw 920, the nut 930 is connected to the lead screw 920, the nut 930 is fixedly connected to the X-axis slide 940, the second motor 910 is fixed to the base 950, the X-axis slide 940 is slidably connected to the base 950, and the bottom end of the Z-axis moving module 300 and the bottom end of the bracket 1100 are both fixedly connected to the X-axis slide 940.

[0057] Furthermore, in the embodiments of this application, such as Figure 1 and Figure 8 As shown, the clamping and positioning mechanism 100 and the carrier 500 are spaced apart in the X direction, and the head of the battery cell 620 is located in the gap between the clamping and positioning mechanism 100 and the carrier 500 (similar to a cantilever structure).
