[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0025] Reference Figure 1 , Figure 1 It is a structural schematic diagram of the four-in-one molding machine in this embodiment. In this embodiment, the four-in-one molding machine includes a feeding mechanism 1, a jig reflow mechanism 2, a trimming mechanism 3, a folding mechanism 4, a glue dripping mechanism 5, a hot pressing mechanism 6 and a feeding mechanism 7. The feeding mechanism 1 is used for feeding the battery cell to be formed; the feeding mechanism 7 is used for unloading the battery cell after forming. The jig reflow mechanism 2 has a first transmission path and a second transmission path, the feeding mechanism 1 is connected to the feeding end of the first transmission path, and the unloading end of the second transmission path is connected to the unloading mechanism 7; the first transmission path shapes one side of the battery cell, and the second transmission mechanism shapes the other side of the battery cell, wherein the first transmission path and the second transmission path are respectively provided with a trimming mechanism 3, a folding mechanism 4, a glue dripping mechanism 5 and a hot pressing mechanism 6, and the trimming mechanism 3, the folding mechanism 4, the glue dripping mechanism 5 and the hot pressing mechanism 6 respectively perform trimming, folding, glue dripping and hot pressing processes on the battery cell to complete the shaping of the battery cell.

[0026] Through the reasonable layout and arrangement of the feeding mechanism 1, the jig reflux mechanism 2, the trimming mechanism 3, the folding mechanism 4, the glue dripping mechanism 5, the hot pressing mechanism 6 and the unloading mechanism 7, the automatic loading, trimming, folding, glue dripping, hot pressing and unloading processes of the battery cell are realized, and the continuity between each process is good, so that the whole battery cell shaping process is smooth, and the forming efficiency of the battery cell is improved.

[0027] Re-reference Figure 1 , further, the feeding mechanism 1 includes a feeding belt 11 and a feeding robot 12. The feeding robot 12 is located between the feeding belt 11 and the feeding end of the first transmission path, wherein the discharge end of the feeding belt 11 is opposite to the feeding robot 12. The feeding belt 11 in this embodiment can adopt a belt-type transmission line, and the formed battery cell is moved by the belt transmission line to a position close to the feeding end of the first transmission path, and then loaded by the feeding robot 12. In this embodiment, the loading robot 12 can adopt a four-axis or six-axis robot, which can adsorb and load the battery cell.

[0028] The battery cell to be formed is placed at the feeding end of the feeding pull belt 11, and then moved to the discharging end of the feeding pull belt 11 under the traction of the feeding pull belt 11. The loading robot 12 absorbs the battery cell to be formed and moves to the reflow jig located at the loading end of the first transmission path. The reflow jig clamps the battery cell to be formed.

[0029] It can be understood that the jig reflow mechanism 2 has a reflow jig, which is used to carry and clamp the battery cell, and the loading robot 12 loads the battery cell into the reflow jig. The reflow jig can be cyclically moved on the first transmission path and the second transmission path, and multiple reflow jigs are evenly distributed on the first transmission path and the second transmission path. Each reflow jig can be loaded with a corresponding battery cell, so that multiple battery cells can move on the first transmission path and the second transmission path at the same time. The four-in-one molding machine can shape multiple battery cells at the same time to improve efficiency.

[0030] Re-reference Figure 1 Furthermore, the jig reflow mechanism 2 includes a first transmission mechanism 21, a transfer mechanism 22 and a second transmission mechanism 23. The first transmission mechanism 21 is arranged on the first transmission path, the second transmission mechanism 23 is arranged on the second transmission path, and the transfer mechanism 22 is respectively connected to the unloading end of the first transmission path and the loading end of the second transmission path, and the transfer mechanism 22 changes the processing direction of the battery cell.

[0031] The first transmission mechanism 21 is used to drive the reflow jig to move on the first transmission path, the second transmission mechanism 23 is used to drive the reflow jig to move on the second transmission path, and the transfer mechanism 22 is used to transfer the battery cells in the reflow jig of the first transmission path to the reflow jig of the second transmission path, and change the processing direction of the battery cells. Preferably, the first transmission path and the second transmission path are arranged side by side, the unloading end of the first transmission path is opposite to the loading end of the second transmission path, and the loading end of the first transmission path is opposite to the unloading end of the second transmission path. In this embodiment, the first transmission path and the second transmission path can adopt guide rails. The transfer mechanism 22 is located between the unloading end of the first transmission path and the loading end of the second transmission path, and is opposite to the unloading end of the first transmission path and the loading end of the second transmission path, respectively. Preferably, there are two transfer mechanisms 22, and the other transfer mechanism 22 is located between the loading end of the first transmission path and the unloading end of the second transmission path, and is respectively opposite to the loading end of the first transmission path and the unloading end of the second transmission path. The transfer mechanism 22 is used to move the reflux jig at the unloading end of the second transmission path to the loading end of the first transmission path, so that the reflux jig that has unloaded the battery cells is recirculated to the loading end of the first transmission path, and again carries the battery cells loaded by the loading robot 12.

[0032] The first transmission mechanism 21 in this embodiment can adopt a single-axis manipulator. Specifically, the first transmission mechanism 21 is three single-axis manipulators arranged in sequence. The three single-axis manipulators are connected end to end in sequence, and two adjacent single-axis manipulators cooperate with each other to drive the reflux fixture to move on the first transmission path. The single-axis manipulator is provided with a cylinder and a clamp connected to the output end of the cylinder. For example, the clamp can adopt a clamping plate structure adapted to the reflux fixture. During driving, the cylinder drives the clamp to clamp the reflux fixture, and the single-axis manipulator then drives the cylinder to move, synchronously driving the reflux fixture to move on the first transmission path. The structure and actuation principle of the second transmission mechanism 23 are consistent with those of the first transmission mechanism 21, which will not be repeated here. The transfer mechanism 22 can also adopt the cooperation of a single-axis manipulator, a cylinder and a clamp, which will not be repeated here.

[0033] Preferably, the first transmission mechanism 21 and the second transmission mechanism 23 are both arranged on the inner side of the first transmission path and the second transmission path. Two groups of trimming mechanisms 3, folding mechanisms 4, glue dripping mechanisms 5 and hot pressing mechanisms 6 are respectively arranged on the outer sides of the first transmission path and the second transmission path opposite to each other; one of the trimming mechanisms 3, folding mechanisms 4, glue dripping mechanisms 5 and hot pressing mechanisms 6 is arranged in sequence along the transmission direction of the first transmission path; the other trimming mechanisms 3, folding mechanisms 4, glue dripping mechanisms 5 and hot pressing mechanisms 6 are arranged in sequence along the transmission direction of the second transmission path. The first transmission mechanism 21 and the second transmission mechanism 23 respectively migrate the reflow fixtures on the first transmission path and the second transmission path, thereby moving the battery cells.

[0034] The battery cell to be formed is first loaded by the loading mechanism 1 onto the reflux fixture at the loading end of the first transmission path; then, driven by the first transmission mechanism 21, the battery cell passes through the trimming mechanism 3, the folding mechanism 4, the glue dripping mechanism 5 and the hot pressing mechanism 6 in sequence, and the above mechanisms perform trimming, folding, glue dripping and hot pressing processes on one side of the battery cell in sequence, and the battery cell with one side shaped is moved to the unloading end of the first transmission path; then, the battery cell is moved to the loading end of the second transmission path by a transfer mechanism 22; and then on the second transmission path, the battery cell is transferred to the unloading end of the first transmission path; Driven by the mechanism 23, the battery cell passes through the trimming mechanism 3, the folding mechanism 4, the glue dripping mechanism 5 and the hot pressing mechanism 6 in sequence. The above mechanisms perform trimming, folding, glue dripping and hot pressing processes on the other side of the battery cell in sequence to shape the other side of the battery cell. The battery cell with the shaped other side is moved to the unloading end of the second transmission path; finally, the unloading mechanism 7 unloads the shaped formed battery cell, and the reflow jig is moved to the loading end of the first transmission path by another transfer mechanism 22, and the next battery cell to be formed is loaded to the reflow jig by the loading mechanism 1.

[0035] The two transfer mechanisms 22 and the first transmission path and the second transmission path arranged side by side together form a "mouth"-shaped reflux transmission line. The remaining trimming mechanisms 3, folding mechanisms 4, glue dripping mechanisms 5 and hot pressing mechanisms 6 are reasonably arranged around the above-mentioned reflux transmission line, and the trimming, folding, glue dripping and hot pressing processes are performed on the two side edges of the battery cell in turn. The entire shaping process is smooth, efficient, and occupies a small area.

[0036] Re-reference Figure 1 Furthermore, the second transmission mechanism 23 has a cell reversing mechanism 231. The cell reversing mechanism 231 faces the feeding end of the second transmission path, and is used for positioning and limiting when the transfer mechanism 22 transfers the cell to the second transmission path. It is worth noting that when the cell is transferred to the second transmission path after the shaping of one side is completed on the first transmission path, the reversal can be completed by simply moving the cell horizontally through the transfer mechanism 22. Because the first transmission path and the second transmission path are arranged side by side, after the cell that has completed the shaping of one side on the first transmission path is translated, its other side just faces each shaping mechanism arranged on the second transmission path, so that the reversal can be achieved. During the whole process, the cell moves with the reflow fixture, and the cell itself does not need to be reversed. The setting of the cell reversing mechanism 231 is to assist the transfer mechanism 22 in transferring the reflow fixture carrying the cell to the second transmission mechanism 23 smoothly and accurately, so as to ensure the smooth progress of the entire shaping process. Specifically, the battery cell reversing mechanism 231 is a driving member that drives the limiting plate to limit the reflow fixture, so that the reflow fixture migrated from the transfer mechanism 22 can move directly onto the guide rail of the second transmission path. The driving member in this embodiment can be a cylinder.

[0037] The trimming mechanism 3 is used to cut off the excess skirt of the battery cell. Specifically, it can use the cooperation of a driving member and a cutter to achieve the cutting of the skirt, or it can use a trimming machine, which will not be described in detail here.

[0038] Re-reference Figure 1 Furthermore, the folding mechanism 4 includes an angle folding mechanism 41 and a single folding mechanism 42. The angle folding mechanism 41 and the single folding mechanism 42 are sequentially arranged along the transmission direction of the first transmission path.

[0039] After the redundant skirt of the battery cell is cut off, the battery cell is transferred by the first transmission mechanism 21 to the folding mechanism 41 for folding the battery cell, so that the skirt of the battery cell is bent. After the folding is completed, the battery cell is transferred by the first transmission mechanism 21 to a folding mechanism 42, so that the folded skirt is folded to 180 degrees, that is, the folded skirt is pressed, so that the edge of the folded corner is folded 180 degrees. The folding mechanism 41 in this embodiment can adopt a folding machine, which will not be described here.

[0040] Preferably, a folding mechanism 42 includes a driving member, a screw member and a folding assembly, the screw member is connected to the driving member and the folding assembly respectively, the driving member is a motor, and the motor drives the screw member to drive the folding assembly to move to the side of the reflow fixture; the folding assembly includes two groups of rollers arranged side by side in the upper and lower positions, and the folding of the cell skirt 180 is completed by setting chamfers of different sizes on the rollers. For example, the size of the chamfer of the upper group of rollers increases from left to right, while the size of the chamfer of the lower group of rollers decreases from left to right. Preferably, the distance between the upper and lower groups of rollers is adjustable.

[0041] Preferably, the folding mechanism 4 further includes a folding and hot-ironing mechanism 43. The folding mechanism 41, the folding mechanism 42 and the folding and hot-ironing mechanism 43 are arranged in sequence along the transmission direction of the first transmission path. After the skirt of the battery cell is folded 180 degrees, it is transmitted to the folding and hot-ironing mechanism 43 by the first transmission mechanism 21. The folding and hot-ironing mechanism 43 performs hot-ironing on the folded skirt to make the folded skirt neat and convenient for subsequent processes. The folding and hot-ironing mechanism 43 in this embodiment can use a hot-ironing machine, which will not be described in detail here.

[0042] After the first folding and hot pressing mechanism 43 presses the folded skirt, the battery cell is transferred to the glue dripping mechanism 5 by the first transmission mechanism 21, and the glue dripping mechanism 5 drips glue on the folded skirt to facilitate the bonding of the folded skirt in the subsequent process. Specifically, the glue dripping of the glue dripping mechanism 5 can be achieved by a glue dispenser, which will not be described in detail here.

[0043] Re-reference Figure 1 Furthermore, the ironing mechanism 6 includes a two-folding mechanism 61 and a two-folding and hot-ironing mechanism 62. The two-folding mechanism 61 and the two-folding and hot-ironing mechanism 62 are arranged in sequence along the transmission direction of the first transmission path.

[0044] The folded skirt of the battery cell is glued and then moved to the double folding mechanism 61 to be bent again. The double folding mechanism 61 bends the skirt 90 degrees so that the skirt is close to the side of the battery cell. The double folding hot pressing mechanism 62 presses the 90-degree bent skirt onto the side of the battery cell, and allows the glue to melt and spread, so that the skirt is shaped.

[0045] Preferably, the ironing mechanism 6 also includes a cold ironing mechanism 63. The two-folding mechanism 61, the two-folding hot ironing mechanism 62 and the cold ironing mechanism 63 are sequentially arranged along the transmission direction of the first transmission path. The cold ironing mechanism 63 can solidify the glue and completely shape the skirt. After the skirt is shaped, the shaping of one side of the battery cell can be completed to obtain a semi-formed battery cell. The number of the two-folding hot ironing mechanism 62 and the cold ironing mechanism 63 in this embodiment are both two, and the two two-folding hot ironing mechanisms 62 are arranged side by side, and the two cold ironing mechanisms 63 are arranged side by side. Such an arrangement facilitates better shaping and fixing of the sides of the battery cells. The cold ironing mechanism in this embodiment can adopt a cold ironing machine, which will not be described here.

[0046] Preferably, the hot pressing mechanism 6 further includes a rolling mechanism 64. The rolling mechanism 64 is located between the double folding mechanism 61 and the double folding hot pressing mechanism 62. Specifically, the rolling mechanism 64 has a driving member and a roller, and the driving member can drive the roller to roll. After the double folding mechanism 61 bends the skirt 90 degrees, the roller of the rolling mechanism 64 rolls on the outer surface of the skirt, so that the skirt is more closely attached to the side of the battery cell, and the glue of the skirt is further spread.

[0047] Re-reference Figure 1 Furthermore, the battery cell that has completed the shaping of one side is moved to the reflow fixture on the second transmission path through the transfer mechanism 22, and the trimming mechanism 3, the folding mechanism 41, the one-folding mechanism 42, the one-folding hot ironing mechanism 43, the glue dripping mechanism 5, the two-folding mechanism 61, the rolling mechanism 64, the two side-by-side two-folding hot ironing mechanisms 62, and the two side-by-side cold ironing mechanisms 63, which are arranged in sequence along the transmission direction of the second transmission path, respectively perform trimming, folding, 180-degree folding, hot ironing, glue dripping, 90-degree folding, rolling, hot ironing and cold ironing on the other side of the battery cell to complete the shaping of the other side of the battery cell, and then complete the shaping of the entire battery cell to obtain a formed battery cell.

[0048] Re-reference Figure 1 Furthermore, the unloading mechanism 7 includes an unloading robot 71 and a tray recovery system 72. The unloading robot 71 is located between the unloading and hot-stamping mechanism 102 and the tray recovery system 72, and transfers the cells hot-stamped by the unloading and hot-stamping mechanism 102 to the tray recovery system 72 for recovery. In this embodiment, the unloading robot 71 can be a four-axis or six-axis robot.

[0049] Preferably, the unloading robot 71 is integrated with a CCD image recognition system, which can accurately adsorb and grasp the battery cells and perform image detection on the battery cells.

[0050] Preferably, the unloading mechanism 7 further includes an unloading NG position 73. The unloading NG position 73 is arranged on one side of the unloading robot 71. When the CCD image recognition system of the unloading robot 71 recognizes a battery cell with obvious deformation, the battery cell will be moved to the unloading NG position 73 for subsequent processing.

[0051] Re-reference Figure 1 Furthermore, the four-in-one molding machine in this embodiment further includes a first positioning mechanism 8. The first positioning mechanism 8 is located on one side of the first transmission path, and is used for positioning the battery cell before trimming. Before the battery cell undergoes the trimming process, the battery cell is accurately positioned to ensure accurate trimming and subsequent folding, glue dripping and hot pressing processes.

[0052] Preferably, the first positioning mechanism 8 includes left and right positioning modules 81 and a jig opening and closing module 82. The jig opening and closing module 82 and the left and right positioning modules 81 are sequentially arranged along the transmission direction of the first transmission path. Among them, the left and right positioning modules 81 have a left positioning module and a right positioning module. During positioning, the left positioning module and the right positioning module are respectively located on the opposite sides of the battery cell, that is, the left and right sides of the battery cell. The left positioning module includes a multi-stroke cylinder and a push plate. The multi-stroke cylinder drives the push plate to position the left side of the battery cell. The right positioning module includes a single-axis manipulator and a push plate. The single-axis manipulator drives the push plate to position the right side of the battery cell. Preferably, the back of the two push plates used for positioning are provided with springs, which are connected to the multi-stroke cylinder or the single-axis manipulator through the spring to avoid damage to the battery cell caused by hard thrust during positioning. The fixture opening and closing module 82 includes a pulling part and a pressing part. The pulling part includes a single-axis mechanical hand and a clamping position. The single-axis manipulator drives the clamping position to move to the opening and closing position of the reflow fixture. The clamping position clamps the opening and closing position, and then the single-axis manipulator drives the clamping position to pull up to open the clamping part of the reflow fixture. At this time, the left and right positioning modules 81 accurately position the battery cell. The clamping part includes a cylinder and a pressing block. The cylinder drives the pressing block to press against the opening and closing position of the reflow fixture and press down, so that the clamping part of the reflow fixture clamps the battery cell that has been positioned.

[0053] After the first positioning mechanism 8 accurately positions the battery cell in the reflow jig, the battery cell to be formed is transferred by the first transmission mechanism 21 to the trimming mechanism 3 for trimming. It can be understood that the external dimensions of the lithium battery have precise requirements. In order to make the external dimensions of the lithium battery meet the design requirements, the skirt of the lithium battery has a preset length, that is, the skirt of the battery cell in this embodiment. The trimming mechanism 3 is used to cut off the excess part of the skirt of the lithium-ion battery so that the skirt of the battery cell reaches the preset length, and it is necessary to ensure that the edge of the trimming is flat. The setting of the first positioning mechanism 8 allows the battery cell to be accurately positioned at a predetermined position in the reflow jig, and the trimming mechanism 3 can accurately cut off the excess part of the battery cell skirt according to the accurate preset length.

[0054] Re-reference Figure 1 Furthermore, the four-in-one molding machine in this embodiment also includes a second positioning mechanism 9. The second positioning mechanism 9 is arranged above the loading position of the loading mechanism 1, and is used to position the battery cell before loading. In this embodiment, the second positioning mechanism 9 is arranged above the discharge end of the feed pull belt 11. When the battery cell to be formed moves to the discharge end of the feed pull belt 11, the second positioning mechanism 9 positions the battery cell from above and transmits the positioning information to the loading robot, so that the loading robot 12 can accurately clamp the battery cell to be formed. The second positioning mechanism 9 in this embodiment is a CCD imaging system.

[0055] Preferably, the second positioning mechanism 9 is integrated into the adsorption end of the loading robot 12, which can also achieve the positioning and adsorption function.

[0056] Preferably, the CCD imaging system of the second positioning mechanism 9 also has a detection function. When the second positioning mechanism 9 detects that the battery cell to be formed has obvious defects, for example, there are clear scratches on the surface, the loading robot 12 will transfer the battery cell to be formed to the loading NG position 13 located on one side of the loading robot 12.

[0057] Re-reference Figure 1 Furthermore, the four-in-one forming machine in this embodiment also includes a pre-cutting hot stamping mechanism 10. The pre-cutting hot stamping mechanism 10 includes a cutting piece 101 and a cutting hot stamping mechanism 102. The two ends of the cutting piece 101 are respectively opposite to the cutting end of the second transmission path and the cutting hot stamping mechanism 102. The cutting piece 101 is used to transfer the battery cells on the cutting end of the second transmission path to the cutting hot stamping mechanism 102, and the cutting hot stamping mechanism 102 performs hot stamping on the battery cells, that is, a secondary hot stamping after cold stamping, so that the shaping of the battery cells is complete. The cutting piece 101 can use a single-axis robot.

[0058] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
