Description

Technical Field

[0001] This utility model relates to the technical field of stamping and folding devices, and in particular to a centering stamping and folding device. Background Technology

[0002] Currently, the upper and lower casings of button batteries need to be stamped using a stamping and folding device to fold them into a specified shape. To improve the production efficiency of folding, most manufacturers currently use a rotary platform for feeding and unloading materials. Specifically, the rotary platform is equipped with at least two folding bases (also known as folding lower dies). The folding sleeve (also known as folding upper die) above the rotary platform and one of the folding bases press against each other to fold the material. The rotary platform then drives multiple folding bases to rotate, so that the next folding base loaded with unfolded material quickly moves to the bottom of the folding sleeve. At the same time, the folding base loaded with folded material moves to the unloading station, thus efficiently completing the folding operation of the material.

[0003] The existing stamping and folding equipment suffers from poor concentricity accuracy between the folding base and the folding sleeve, resulting in a high rate of elliptical defects in the stamped upper and lower casings. This increases the risk of battery leakage after assembly. Furthermore, defective upper and lower casings are prone to damaging the cells or tabs after assembly, leading to poor internal resistance in the button cell. Additionally, the small size of the button cell's upper and lower casings makes them susceptible to damage during the stamping and folding process. Furthermore, when it is necessary to change to a different size of upper or lower shell stamping, the corresponding folding sleeve and all folding bases need to be replaced. During the installation of the new folding sleeve and folding bases, since there is no installation reference for the folding bases on the rotating platform, it is difficult to adjust all the folding bases to be concentric with the same circular path as the rotating platform. Moreover, the installation accuracy of the rotating platform is also poor, and the position of the rotating platform is prone to deviation. These factors ultimately lead to the problem of great difficulty in adjusting the concentricity between the folding sleeve and the folding base. If the adjustment is not in place, there will always be one or more folding bases that are severely misaligned with the folding sleeve during the folding process (i.e., the concentricity between the folding base and the folding sleeve is poor). Therefore, a lot of debugging time is required each time production changes, and the training cycle for debugging personnel is also long, which is difficult to meet the needs of rapid production changeover of button batteries. Therefore, it is necessary to improve the existing stamping and folding device.

[0004] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0005] This utility model provides a centering stamping and folding device, which mainly solves the problem of existing stamping and folding devices facing the production requirements of high concentricity centering, and at the same time solves the technical problem of difficulty in model change and debugging.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A centering stamping and folding device includes a lifting drive mechanism, a folding sleeve, a rotary drive mechanism, a rotary platform, an adjustment fixture, and at least two folding bases.

[0008] The rotary drive mechanism is positioned and connected to the rotary platform via pins and is used to drive the rotary platform to rotate. The rotary platform is provided with multiple mounting references arranged along the circumferential direction. Multiple folding bases are fixed to the multiple mounting references one by one. The multiple mounting references make the center lines of the multiple folding bases lie on the same circular path, and the center of the circular path coincides with the first rotation axis of the rotary platform. The folding sleeve is located above the rotary platform. The lifting drive mechanism is connected to the folding sleeve and is used to drive the folding sleeve to move up and down. The debugging fixture includes a concentric first end and a second end. The first end is used to cooperate with one of the folding bases, and the second end is used to cooperate with the folding sleeve.

[0009] In one of the technical solutions, the centering stamping and folding device further includes an adjustment platform, which is connected to the lifting drive mechanism or between the lifting drive mechanism and the folding sleeve, and is used to fine-tune the position of the folding sleeve so that the folding sleeve can be aligned and concentric with the folding base.

[0010] In one of the technical solutions, the lifting drive mechanism includes a base, a driver, and a lifting seat;

[0011] The driver is fixed to the base, the lifting seat is slidably connected to the base in the longitudinal direction, the driver is connected to the lifting seat and is used to drive the lifting seat to move up and down, the folded sleeve is connected to the lifting seat; the adjustment platform is connected to the base or connected between the driver and the lifting seat.

[0012] In one of the technical solutions, the lifting drive mechanism further includes a guide column fixed on the lifting seat, and a guide sleeve that cooperates with the guide column is fixed on the rotating platform. When the guide column is inserted downward into the guide sleeve, the folding sleeve does not contact the workpiece to be folded located on the folding base.

[0013] In one of the technical solutions, the lifting drive mechanism further includes a pressure rod and an elastic element. The pressure rod is slidably connected to the lifting seat and passes through the folded sleeve. The elastic element is sleeved on the pressure rod. The pressure rod has a downward movement tendency relative to the lifting seat due to the elastic force of the elastic element, and the lower surface of the pressure rod in the initial position is lower than the lower surface of the folded sleeve.

[0014] In one of the technical solutions, the adjustment platform includes a connected manual X-axis adjustment mechanism and a manual Y-axis adjustment mechanism, and the base is mounted on the manual Y-axis adjustment mechanism.

[0015] In one of the technical solutions, the rotating platform is provided with a plurality of mounting slots arranged along the circumferential direction, and a plurality of the folded bases are installed on the mounting slots in a corresponding manner, the wall of the mounting slot serving as the mounting reference.

[0016] In one of the technical solutions, a heater is fixed on the rotating platform, and at least one heat insulation plate is connected between the rotating platform and the rotating drive mechanism. The heat insulation plate and the rotating drive mechanism, the heat insulation plate and the heat insulation plate, and the heat insulation plate and the rotating platform are all positioned and connected by pins.

[0017] In one of the technical solutions, the rotary drive mechanism includes a fixed base, a power unit, a rack, a gear, a rotating rod, and a mounting plate;

[0018] The power unit is fixed to the fixed base, the rack is slidably connected to the fixed base, the gear is sleeved and fixed to the rotating rod, the rotating rod is rotatably connected to the fixed base and extends longitudinally, the power unit is connected to the rack and is used to drive the rack to slide relative to the fixed base, the rack meshes with the gear to drive the gear and the rotating rod to rotate together, the mounting plate is fixed above the rotating rod, and the bottom heat insulation plate is positioned and connected to the mounting plate by a pin.

[0019] In one of the technical solutions, a negative pressure channel is provided inside the rotating rod, a first negative pressure cavity is provided inside the mounting plate, a second negative pressure cavity is provided inside each of the heat insulation plates, a third negative pressure cavity is provided inside the rotating platform, and an adsorption hole is provided on the top surface of the folded base. The negative pressure channel, the first negative pressure cavity, the second negative pressure cavity, the third negative pressure cavity and the adsorption hole are connected in sequence.

[0020] Compared with the prior art, the centering stamping and folding device provided by this utility model has at least the following beneficial effects:

[0021] This solution sets multiple mounting references arranged along the circumference on the rotating platform. After the multiple folded bases are fixed on their respective mounting references, the center lines of the multiple folded bases will all be located on the same circular path. The center of this circular path is designed to coincide with the center of the rotating platform. Furthermore, this solution also designs the rotating platform to be precisely positioned and connected to the rotating drive mechanism by means of pin positioning, thereby improving the installation accuracy of the rotating platform and ensuring that the center of the rotating platform can coincide with the first rotation axis on the rotating drive mechanism. This allows the multiple folded bases to rotate precisely around the first rotation axis, that is, it ensures that the multiple folded bases fixed on the rotating platform will not move eccentrically. With this solution, during changeover production, the new folding base only needs to be installed on the same mounting reference. There is no need to adjust the position of the rotating platform and multiple folding bases. Then, the position of the folding sleeve can be finely adjusted using the adjustment fixture to quickly achieve the goal of centering and concentricity between the folding sleeve and the folding base. The centering stamping and folding device of this solution can meet the production requirements of high concentricity precision centering and folding for small products (such as the upper or lower shell of button batteries), and also has the advantage of efficient changeover production.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0036] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Please refer to the following: Figures 1 to 4This utility model provides a centering stamping and folding device, mainly including a lifting drive mechanism 1, a folding sleeve 2, a rotating drive mechanism 3, a rotating platform 4, and at least two folding bases 6. The rotating drive mechanism 3 is connected to the rotating platform 4 and drives the rotating platform 4 to rotate around a first rotation axis 30. Multiple folding bases 6 are fixed on the rotating platform 4 to rotate with it. This embodiment mainly uses only two folding bases 6 on the rotating platform 4. The folding sleeve 2 is positioned above the rotating platform 4. The lifting drive mechanism 1 is connected to the folding sleeve 2 and drives it to move up and down. During operation, the workpiece 10 to be stamped and folded is placed on each folding base 6. Then, the rotating drive mechanism 3 drives the rotating platform 4 and the multiple folding bases 6 to rotate. Under the drive of the rotating drive mechanism 3, the multiple folding bases 6 can move to the bottom of the folding sleeve 2. The folding sleeve 2 moves downward under the drive of the lifting drive mechanism 1, so that it can work together with each folding base 6 to stamp and fold the workpiece 10.

[0038] Please refer to them again. Figures 1 to 4In this embodiment, multiple mounting references 41 arranged along the circumferential direction are set on the rotating platform 4. The multiple folded bases 6 are installed on the multiple mounting references 41 one by one. After the multiple folded bases 6 are fixed on the corresponding mounting references 41, the center lines of the multiple folded bases 6 will all be located on the same circular path 9. The center of this circular path 9 is designed to coincide with the center O of the rotating platform 4. Furthermore, in this embodiment, the rotating platform 4 is also designed to be precisely positioned and connected to the rotating drive mechanism 3 through pins 7, thereby improving the installation accuracy of the rotating platform 4 and ensuring that the center O of the rotating platform 4 can coincide with the first rotation axis 30 on the rotating drive mechanism 3. This allows the multiple folded bases 6 to rotate precisely with the first rotation axis 30 as the rotation axis, that is, ensuring that the multiple folded bases 6 fixed on the rotating platform 4 will not move eccentrically. Furthermore, the centering stamping and folding device in this embodiment also includes an adjustment fixture 5. The adjustment fixture 5 specifically includes a first end 51 and a second end 52 that are concentric with each other. The first end 51 is used to cooperate with the folding base 6, and the second end 52 is used to cooperate with the folding sleeve 2. That is, after the folding sleeve 2 and the folding base 6 are respectively cooperated with the adjustment fixture 5, the folding sleeve 2 can be adjusted to be concentrically aligned with the folding base 6. Specifically, with this solution, during changeover production, it is only necessary to install the new folding base 6 on the same mounting reference 41. It is no longer necessary to adjust the position of the rotating platform 4 and the multiple folding bases 6. Then, by using the adjustment fixture 5 to finely adjust the position of the folding sleeve 2, the concentric alignment of the folding sleeve 2 and the folding base 6 can be quickly achieved. The centering stamping and folding device of this solution can meet the production requirements of high concentricity accuracy centering and folding for small products (such as the upper or lower shell of a button battery), and also has the advantage of efficient changeover production.

[0039] Please see Figure 4 The rotating platform 4 is provided with multiple mounting slots 42 arranged along the circumferential direction. Multiple folded bases 6 are installed in these mounting slots 42 one by one. The wall of the mounting slot 42 is actually understood as the mounting reference 41 mentioned above. By abutting each folded base 6 against the wall of the corresponding mounting slot 42, the center of multiple folded bases 6 can be quickly made to fall on the circular path 9, thereby ensuring that the multiple folded bases 6 after the transformation can still rotate around the first rotation axis 30. In other embodiments, multiple high-precision protrusions can also be provided on the rotating platform 4, and then each folded base 6 can abut against the side wall of the corresponding protrusion one by one. In this case, the center of multiple folded bases 6 can also be quickly made to fall on the circular path 9. In this case, the side wall of the protrusion is understood as the mounting reference 41 mentioned above.

[0040] Please refer to the following: Figures 1 to 4The stamping and folding device in this embodiment also includes an adjustment platform 8, which is used to fine-tune the position of the folding sleeve 2 so as to adjust the position of the folding sleeve 2 to be concentric with the folding base 6. In this embodiment, the adjustment platform 8 is preferably designed to be connected to the lifting drive mechanism 1, that is, during the process of adjusting the position of the folding sleeve 2, the lifting drive mechanism 1 will also move along with the folding sleeve 2.

[0041] In other embodiments, the adjustment platform 8 described above can also be connected between the lifting drive mechanism 1 and the folding sleeve 2. In this embodiment, when the lifting drive mechanism 1 drives the folding sleeve 2 to move up and down, the adjustment platform 8 will move up and down along with the folding sleeve 2.

[0042] Please see Figure 1 The lifting drive mechanism 1 specifically includes a base 11, a driver 12, and a lifting seat 13. The driver 12 is fixed to the base 11 and is preferably a low-cost cylinder. The lifting seat 13 is longitudinally slidably connected to the base 11 via a slide rail. The driver 12 connects to the lifting seat 13 and drives it to move up and down. The aforementioned folding sleeve 2 is fixed to the lifting seat 13 to move up and down with it. The adjusting platform 8 is actually connected to the base 11 or between the driver 12 and the lifting seat 13. Using this lifting drive mechanism 1, the function of the folding sleeve 2 moving up and down is specifically realized, allowing the folding sleeve 2 and the lower folding base 6 to jointly perform stamping and folding on the workpiece 10. More specifically, the lifting drive mechanism 1 in this embodiment also includes multiple guide columns 14, which are all fixed on the lifting seat 13. Correspondingly, multiple guide sleeves 43 are fixed on the rotating platform 4. The guide columns 14 and guide sleeves 43 are inserted into each other in a one-to-one correspondence. Moreover, when the guide column 14 is inserted downward into the corresponding guide sleeve 43, the folding sleeve 2 still does not contact the workpiece 10 to be folded located on the folding base 6. With this design, it is possible to prevent the folding sleeve 2 and the folding base 6 from shifting their positions when pressing the workpiece 10 against each other, thereby further improving the concentricity of the folding sleeve 2 and the folding base 6 when pressing and folding the workpiece 10.

[0043] Please see Figure 1 The adjustment platform 8 specifically includes a connected manual X-axis adjustment mechanism 81 and a manual Y-axis adjustment mechanism 82, with the aforementioned base 11 essentially mounted on the manual Y-axis adjustment mechanism 82. This design allows the folded sleeve 2 to be adjusted in both the X and Y directions, facilitating the alignment and concentricity of the folded sleeve 2 and the folded base 6.

[0044] Please refer to the following: Figure 1 and Figure 2The lifting drive mechanism 1 also includes a pressure rod 15 and an elastic element 16. The pressure rod 15 is slidably connected longitudinally to the lifting seat 13 via a connecting linear bearing. The pressure rod 15 also passes through the inner ring of the flanged sleeve 2. The elastic element 16 is sleeved on the pressure rod 15 and is preferably a spring. When the pressure rod 15 is subjected to the elastic force of the elastic element 16, it will have a tendency to move downwards relative to the lifting seat 13. Furthermore, when the pressure rod 15 is in its initial position, its lower surface is designed to be lower than the lower surface of the flanged sleeve 2. Specifically, when the driver 12 of the lifting drive mechanism 1 drives the lifting seat 13, pressure rod 15, elastic element 16, and folding sleeve 2 to move downward together, the pressure rod 15 will first contact the workpiece 10 located on the folding base 6, thereby pressing the central area of ​​the workpiece 10. Then, the folding sleeve 2 will contact the workpiece 10 downward and together with the folding base 6 will perform stamping and folding on the workpiece 10. After the stamping and folding are completed, the driver 12 drives the lifting seat 13, pressure rod 15, elastic element 16, and folding sleeve 2 to move upward and reset. As the folding sleeve 2 moves upward away from the workpiece 10, the pressure rod 15 will still press the workpiece 10 due to the elastic force of the elastic element 16, preventing the workpiece 10 from being stuck to the folding sleeve 2 and moving upward with the folding sleeve 2, ensuring that the workpiece 10 remains on the folding base 6 with high positional accuracy. Only when the pressure rod 15 is reset to the initial position relative to the lifting seat 13 will the lifting seat 13 move upward away from the workpiece 10 together with the pressure rod 15. It can be seen that by setting the pressure bar 15 and the elastic element 16, the reliability and stability of the stamping and bending of the workpiece 10 can be improved.

[0045] Please refer to the following: Figure 1 , Figure 2 and Figure 4 A heater (not shown in the figure) is fixed on the rotating platform 4. In actual operation, the rotating platform 4 can conduct the heat of the heater to each folding base 6, thereby heating the workpiece 10 on each folding base 6. By heating the workpiece 10 and then stamping and folding it, the workpiece 10 can be softened and the internal stress of the workpiece 10 can be eliminated, preventing the workpiece 10 from having a serious springback after stamping and folding, thereby improving the accuracy of stamping and folding the workpiece 10. In order to prevent heat from spreading to the rotary drive mechanism 3 and affecting its rotational accuracy, based on the heat conduction structure design of the rotary platform 4, at least one heat insulation plate 200 is connected between the rotary platform 4 and the rotary drive mechanism 3. At the same time, the heat insulation plate 200 is connected to the rotary drive mechanism 3, to the heat insulation plate 200 and to the rotary platform 4 by means of pins 7, so as to ensure that even if the heat insulation plate 200 is set, the center O of the rotary platform 4 can still fall accurately on the first rotation axis 30, thereby ensuring that the multiple folded bases 6 can still rotate around the first rotation axis 30.

[0046] Please refer to them again. Figure 1 , Figure 2 and Figure 4 The rotary drive mechanism 3 specifically includes a fixed base 31, a power unit 32, a rack 33, a gear 34, a rotating rod 35, and a mounting plate 36. The power unit 32 is preferably a low-cost cylinder. The power unit 32 is fixed on the fixed base 31. The rack 33 and the fixed base 31 are slidably connected by a connecting guide rail. The gear 34 is sleeved and fixed on the rotating rod 35. The rotating rod 35 is rotatably connected to the fixed base 31 by a connecting bearing. The rotating rod 35 extends longitudinally, and the axis of the rotating rod 35 is the first rotation axis 30 mentioned above. The power unit 32 is connected to the rack 33 and is used to drive the rack 33 to slide relative to the fixed base 31. The rack 33 and the gear 34 mesh with each other. The mounting plate 36 is fixed to the top of the rotating rod 35. The bottom heat insulation plate 200 is fixedly connected to the mounting plate 36 by a pin 7. During operation, the power unit 32 drives the rack 33 to move linearly. The rack 33 drives the gear 34, rotating rod 35, mounting plate 36, heat insulation plate 200, rotating platform 4, and multiple folding bases 6 to rotate together, so that all the folding bases 6 can rotate to the bottom of the folding sleeve 2. In addition, the rotating rod 35 in this embodiment is provided with a negative pressure channel (not shown in the figure), the mounting plate 36 is provided with a first negative pressure chamber 361, each heat insulation plate 200 is provided with a second negative pressure chamber 201, the rotating platform 4 is provided with a third negative pressure chamber 44, and the top surface of the folding base 6 is provided with an adsorption hole 61. The negative pressure channel, the first negative pressure chamber 361, the second negative pressure chamber 201, the third negative pressure chamber 44, and the adsorption hole 61 are connected in sequence, so that the folding base 6 can adsorb the workpiece 10, ensuring that the workpiece 10 can always be firmly on the folding base 6 during the stamping and folding process, thereby improving the accuracy of stamping and folding the workpiece 10.

[0047] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way.
