Description

Technical Field

[0001] The invention relates to the technical field of battery top covers, and in particular to a square flip-riveted top cover structure and assembly equipment. Background Art

[0002] Power batteries are important components of new energy vehicles. Most existing new energy batteries use lithium-ion batteries as their power batteries. For power lithium batteries, in addition to key components such as battery cells and BMS, the battery shell structure is also an important factor in its safety. Among them, the pole is a component of the battery module. In addition to being used to connect to the positive and negative electrodes of the battery cells in the module for conduction, it also needs to have corresponding structural strength and sealing requirements to meet the application requirements of the car.

[0003] In the prior art, the pole piece of the battery top cover usually includes a pole body, a seal, a support and other partial structures. In the production process, these structures need to be assembled to the cover plate. In order to improve the assembly efficiency, a transplanting mechanism is currently used for automatic loading. For example, the patent document with the announcement number CN221050916 discloses a transplanting mechanism for assembling the battery top cover, and also discloses a rotating transmission assembly, a lifting transmission assembly, a horizontal transmission assembly, and a negative pressure suction cup.

[0048] In this example, see Figure 2-Figure 3 The positive pole structure 101 and the negative pole structure 102 both include a pole body 2, and a pole hole 103 for mounting the pole body 2 is correspondingly opened on the top cover body 1;

[0049] For details, please refer to Figure 3-Figure 4 The pole body 2 includes a base 204, on which a structural column 205 for penetrating the pole hole 103 is fixedly arranged, and on which a ring-shaped riveted portion 206 is fixedly arranged; it can be explained that in the initial state, the outer circumference of the ring-shaped riveted portion 206 is flush with the outer circumference of the structural column 205, and during assembly, the ring-shaped riveted portion 206 can be folded outwardly so that the outer circumference of the ring-shaped riveted portion 206 is turned 90 degrees, and the folded ring-shaped riveted portion 206 can be referred to Figure 4 .

[0050] A sealing ring 201 is further provided between the pole body 2 and the pole hole 103, and the sealing ring 201 includes a first annular portion 207, and a first annular step 208 is integrally arranged on the side of the first annular portion 207 close to the axis center; it can be explained that, in this embodiment, before the pole body 2 is installed in the pole hole 103, the sealing ring 201 is first sleeved on the structural column 205, and the first annular step 208 is located on the side away from the base 204. After the sleeve is completed, when the structural column 205 is inserted into the pole hole 103, the first annular step 208 is just embedded in the gap between the structural column 205 and the pole hole 103, so as to achieve a preliminary sealing effect.

[0051] As a further solution of this embodiment, please refer to Figure 2-Figure 3 as well as Figure 5The positive pole structure 101 and the negative pole structure 102 also include an upper plastic 202 sleeved on the structural pole 205, the upper plastic 202 includes a first ring body 209, a second annular step 211 is integrated at the side edge of the bottom of the first ring body 209 close to the axis, and a third annular step 210 is integrated at the side edge of the first ring body 209 away from the axis, wherein the third annular step 210 is close to the axis and encloses the first ring body 209 to form an annular groove 212, and a steel ring 203 is embedded in the annular groove 212; it can be explained that after the structural pole 205 is embedded in the pole hole 103, , the upper plastic 202 is also sleeved on the structural column 205, so that the second annular step 211 is embedded in the gap between the structural column 205 and the pole hole 103, and its bottom surface is in contact with the first annular step 208, and then the steel ring 203 is embedded in the annular groove 212, and finally the annular riveted portion 206 is folded. The folded annular riveted portion 206 is tightly fitted with the steel ring 203, and then the upper plastic 202 and the sealing ring 201 can be tightly compressed in the gap between the structural column 205 and the pole hole 103, thereby improving the sealing effect of the positive pole structure 101 and the negative pole structure 102.

[0052] It should be noted that the upper plastic 202 of this embodiment is integrally injection molded by a mold.

[0053] Example 2

[0054] Based on Example 1, please refer to Figure 6-Figure 7 , an assembly device for a square flip-riveted top cover structure, comprising a workbench 3, on which a first loading portion 301 for carrying a top cover body 1 and a second loading portion 302 for carrying a pole body 2 are arranged; specifically, in this embodiment, a plurality of groups of top cover bodies 1 are arranged vertically stacked and placed on the first loading portion 301, and a plurality of groups of pole bodies 2 are arranged vertically stacked and placed on the second loading portion 302, wherein the pole bodies 2 are arranged in two rows on the second loading portion 302 to correspond to the positions of the pole holes 103 on both sides of the top cover body 1.

[0055] The other side of the workbench 3 is also arranged in sequence with a third loading part 304 for carrying the sealing ring 201, a fourth loading part 305 for carrying the upper plastic 202, and a fifth loading part 306 for carrying the steel ring 203; it should be noted that this embodiment does not limit the arrangement order of the third loading part 304, the fourth loading part 305 and the fifth loading part 306.

[0056] It also includes an assembly module arranged on the other side of the workbench 3, and the assembly module is used to assemble the pole body 2, the sealing ring 201, the upper plastic 202 and the steel ring 203 in the pole hole 103 to form the positive pole structure 101 and the negative pole structure 102;

[0057] It can be explained that, in this embodiment, when assembling the positive electrode column structure 101 and the negative electrode column structure 102, the structural components to be assembled are first arranged at the corresponding loading positions, and then the structural components to be assembled can be assembled in the column hole 103 through the assembly module to form the positive electrode column structure 101 and the negative electrode column structure 102. This embodiment does not require manual loading, which can effectively improve the assembly efficiency of the battery top cover structure.

[0058] In this example, see Figure 6-Figure 7 The first loading part 301 includes a first supporting frame 308 arranged on the workbench 3, and both sides of the first supporting frame 308 and the side close to the second loading part 302 are arranged on the limiting plates 307 fixed to the workbench 3, and the three groups of limiting plates 307 and the first supporting frame 308 are enclosed to form a first storage space for stacking the top cover bodies 1; it can be explained that, before the top cover bodies 1 are loaded, several groups of top cover bodies 1 are first placed in the first storage space for storage, and the top cover bodies 1 are limited by the three groups of limiting plates 307 respectively to position the top cover bodies 1, so as to facilitate the subsequent precise loading of each top cover body 1 in sequence.

[0059] For details, please refer to Figure 6-Figure 8 In order to achieve the effect of sequentially loading each top cover body 1, in this embodiment, first guide rods 310 fixed to the workbench 3 are arranged on both sides of the first carrying frame 308, and a first guide plate 309 fixed to the first carrying frame 308 is slidably arranged on the first guide rod 310. A first spring 311 is arranged on the first guide rod 310, and one end of the first spring 311 is fixed to the workbench 3, and the other end thereof is fixed to the first guide plate 309. It can be explained that when arranging the top cover body 1 into the first material storage space, the operator first moves the first carrying frame 308 toward The workbench 3 is pressed in the direction, and the first bearing frame 308 can drive the first guide plate 309 to slide on the first guide rod 310 to compress the first spring 311. After the top cover body 1 to be loaded is placed in the first storage space, based on the elastic force of the first spring 311, an upward force can be given to each top cover body 1. When the topmost top cover body 1 is removed, the first spring 311 can drive the first bearing frame 308 to move upward by a distance of the thickness of the top cover body 1 under the elastic force, so as to facilitate the subsequent loading of the top cover body 1 again;

[0060] Among them, this embodiment can limit the two ends of the top cover body 1 located at the top by setting the lower pressure plate 404, so that each top cover body 1 can be stably stored in the first storage space, achieving the effect of sequential loading.

[0061] As a further solution of this embodiment, in order to load the top cover body 1, the height of the limit plate 307 on the side close to the second loading part 302 is lower than the height of the lower surface of the topmost top cover body 1, wherein a pushing cylinder 4 is fixedly arranged on the side of the workbench 3 away from the second loading part 302, and the driving end of the pushing cylinder 4 is fixed to the pushing seat 401, and the setting height of the pushing seat 401 is only sufficient to push out the topmost top cover body 1; it can be explained that when loading the top cover body 1, the pushing seat 401 is driven by the pushing cylinder 4 to move horizontally toward the direction of the second loading part 302, and the pushing seat 401 can push out the topmost top cover body 1 during the movement.

[0062] In addition, a lower pressure plate 404 is vertically fixed on one end of the pushing seat 401 away from the second loading part 302, and the lower surface of the lower pressure plate 404 is flush with the lower surface of the pushing seat 401; specifically, when the pushing seat 401 pushes the top cover body 1 to move toward the second loading part 302, as the pushing seat 401 separates from the first loading part 301, the lower pressure plate 404 can always crimp the top cover body 1 in the first storage space to avoid interference between the top cover body 1 and the reset pushing seat 401 after it moves up.

[0063] In this embodiment, please refer to Figure 6-Figure 7, the second loading part 302 includes a second carrying frame 405 arranged on the workbench 3, and three groups of first limiting rods 313 fixedly arranged on the workbench 3 in a circumferential array are arranged on both sides of the second carrying frame 405, and the three groups of first limiting rods 313 are enclosed to form a second storage space for stacking the pole bodies 2, and second guide rods 402 fixed to the workbench 3 are arranged on both sides of the second carrying frame 405, and a second guide plate 406 fixed to the second carrying frame 405 is slidably arranged on the second guide rod 402, and a second spring 403 is provided on the second guide rod 402, one end of the second spring 403 is fixed to the workbench 3, and the other end thereof is fixed to the second guide plate 406, wherein the second loading part 302 also includes two groups of card plates 7 for respectively pressing the pole bodies 2 on both sides, and the card plates 7 on both sides are connected to the adjustment mechanism for driving them to approach or move away from each other; it can be explained that the pole bodies 2 are arranged in the second storage space When the load plate 310 is in the second position, the second support frame 405 is moved upward by the second spring 403 to move the second guide plate 406 on the second guide rod 402 to compress the second spring 403. After the pole body 2 to be loaded is placed in the second storage space, the outer edge surface of the pole body 2 slides and abuts against the first limiting rods 313. At this time, the adjusting mechanism drives the two side clamping plates 7 to reset, and the clamping plates 7 can be pressed on the base 204 of the top pole body 2, thereby achieving the effect of limiting the pole body 2. When the pole body 2 and the top cover body 1 need to be assembled, the adjusting mechanism drives the two side clamping plates 7 to separate from the base 204. The second spring 403 can drive the second support frame 405 to move upward by a distance of the thickness of the pole body 2 under the action of the elastic force, and then the two side clamping plates 7 are driven to reset by the adjusting mechanism to limit the pole body 2 again.

[0064] It should also be noted that in this embodiment, when the top cover body 1 is pushed to move toward the second loading part 302, the top cover body 1 just moves to above the second loading part 302, and the pole holes 103 on both sides of the top cover body 1 are respectively coaxial with the pole body 2 in the second storage space on the corresponding side. When the adjustment mechanism drives the clamping plates 7 on both sides to separate from the base 204, the topmost pole body 2 can move up and embed the structural column 205 into the pole hole 103 to achieve assembly.

[0065] See also Figure 7The adjustment mechanism includes a limit seat 701 fixedly arranged on the card plate 7, one end of the limit seat 701 away from the card plate 7 is fixed to the support rod 708, the two sides of the workbench 3 are respectively fixed with the blocking frame 5, and the baffle 710 is fixedly arranged on one side of the blocking frame 5. The end of the support rod 708 away from the limit seat 701 is slidably inserted into the guide hole provided in the baffle 710, and the support rod 708 is provided with a third spring 709, one end of the third spring 709 is fixed to the limit seat 701, and the other end is fixed to the baffle 710 , wherein, a limiting frame 702 is fixedly arranged on one side of the limiting seat 701 on both sides away from the first feeding part 301, and the limiting frame 702 is fixed with the first linear guide 703, and a second linear guide 704 is arranged in parallel on the side close to the first linear guide 703 on both sides, and the length of the second linear guide 704 is less than the length of the first linear guide 703, and the two ends of the first linear guide 703 are symmetrically fixed with inclined guides 705 fixedly connected to the second linear guide 704, L-shaped push frames 407 are fixedly arranged on both sides of the seat 401, and the ends of the L-shaped push frames 407 are rotatably arranged on the guide wheels 408; it can be explained that when the push cylinder 4 pushes the top cover body 1 to move toward the second loading part 302, the push seat 401 can synchronously push the guide wheel 408 to move through the L-shaped push frame 407. As the top cover body 1 moves to the top of the pole body 2, the guide wheel 408 first abuts against the inclined guide frame 705, and then when the guide wheel 408 abuts against the second linear guide frame 704 When in contact, the first linear guide 703 drives the card plate 7 to separate from the base 204 through the limit frame 702, and the third spring 709 is compressed to generate elastic force. At this time, the second spring 403 can drive the second bearing frame 405 to move upward by a distance of the thickness of the pole body 2 under the action of the elastic force, and the annular riveted portion 206 on the pole body 2 abuts against the lower surface of the top cover body 1. When the top cover body 1 moves to the assembly position, the structural column 205 is embedded in the pole hole 103, achieving the effect of automatic assembly;

[0066] When the pushing cylinder 4 drives the pushing seat 401 to return to its original position, the third spring 709 can synchronously drive the clamping plate 7 to return to its original position.

[0067] Furthermore, when the top cover body 1 moves onto the second loading portion 302, in order to prevent the second spring 403 from synchronously lifting the top cover body 1, in this embodiment, please refer to Figure 7-Figure 8, slide rails 707 are symmetrically arranged on both sides of the workbench 3, and the slide rails 707 are used to guide and limit the top cover body 1 pushed out from the first loading part 301. One end of the slide rail 707 is fixed to the limiting plate 307, wherein an upper pressing plate 706 is fixedly arranged on the end of the pushing seat 401 away from the pushing cylinder 4; it can be explained that when the pushing seat 401 is in the initial position on the first loading part 301, the upper pressing plate 706 can be crimped on the top cover body 1 to prevent the top cover body 1 in the first storage space from continuing to move upward, and as the pushing seat 401 pushes the top cover body 1 to move to the second loading part 302, the upper pressing plate 706 can always maintain a state of crimping on the top cover body 1, so that the top cover body 1 is always in the same horizontal plane during the movement, which is convenient for subsequent assembly.

[0068] See also Figure 6 The third loading part 304, the fourth loading part 305 and the fifth loading part 306 respectively include a group of loading plates 312, each loading plate 312 is fixed by a connecting plate, and three groups of second limiting rods 303 are arranged in a circumferential array on both sides of the loading plate 312, and several groups of sealing rings 201, upper plastics 202 and steel rings 203 are respectively sleeved on the three groups of second limiting rods 303; wherein, the assembly module includes a grasping mechanism and a moving mechanism, the grasping mechanism is used to grasp and position the sealing ring 201, upper plastics 202 and steel ring 203, and the moving mechanism is used to move the grasped sealing ring 201, upper plastics 202 and steel ring 203 to the second loading part 302 for assembly with the top cover body 1;

[0069] It can be explained that, in this embodiment, the sealing ring 201, the upper plastic 202 and the steel ring 203 to be assembled are first sleeved on the second limiting rod 303 of the loading plate 312 on the corresponding side. When it is necessary to grab any group of components, the moving mechanism first moves the grabbing mechanism to the corresponding loading plate 312, and then grabs the components through the grabbing mechanism. After the grabbing is completed, the moving mechanism transfers the components to the second loading part 302 for assembly.

[0070] The moving mechanism includes a translation mechanism 501 fixedly arranged on a side baffle 5, a translation bracket 502 is fixedly arranged on the driving end of the translation mechanism 501, a lifting cylinder 503 is fixedly arranged at the end of the translation bracket 502, the driving end of the lifting cylinder 503 is fixed to the lifting plate 6, and the grasping mechanism is arranged on both sides of the lifting plate 6 to grasp and position the sealing ring 201, the upper plastic 202 or the steel ring 203; it can be explained that the translation mechanism 501 of this embodiment drives the lifting cylinder 503 to move to the corresponding position through the translation bracket 502, and the lifting cylinder 503 adjusts the height of the grasping mechanism through the lifting plate 6 to facilitate the grasping and positioning of the sealing ring 201, the upper plastic 202 and the steel ring 203.

[0071] In addition, the translation mechanism 501 of this embodiment can adopt a screw nut transmission mechanism or a synchronous belt mechanism, which is not limited in this embodiment, so as to realize driving the translation bracket 502 to reciprocate along a straight line.

[0072] See also Figure 9-10 as well as Fig.12 The gripping mechanism includes a positioning rod 9 fixedly arranged at both ends of the lifting plate 6, a positioning plate 806 is fixedly arranged on the positioning rod 9, and three sets of guide plates 807 are fixedly arranged in a circumferential array on the positioning plate 806. A guide groove 808 is provided on the guide plate 807, and a pin 809 is slidably arranged in the guide groove 808. Each pin 809 is connected to a pushing part that drives it to move synchronously along the guide groove 808 away from or close to the axis, and the bottom end of each pin 809 is fixed to the clamping seat 801; it can be explained that it is time to align the sealing ring 20 1. When the upper plastic 202 and the steel ring 203 are clamped and positioned, the push part first drives each pin shaft 809 to move along the guide groove 808 to a position close to the axis, and then the lifting cylinder 503 drives the lifting plate 6 to descend to a corresponding height, so that each clamping seat 801 moves to the part to be grasped, and then the push part drives each pin shaft 809 to move in the guide groove 808 in a direction away from the axis, so that the clamping seat 801 abuts against the part, thereby achieving the effect of positioning and clamping, and the lifting cylinder 503 can be reset.

[0073] In this embodiment, the pushing part includes a toothed disc 904 rotatably arranged on the positioning rod 9, the toothed disc 904 is arranged at the bottom of the positioning disc 806, and three groups of arc grooves 905 are arranged on the toothed disc 904 in a circumferential array, and the arc groove 905 extends from the proximal axis end to the distal axis end. The pin shaft 809 is penetrated in the arc groove 905, and two groups of bayonet pins 805 are fixedly arranged on the pin shaft 809, one group of bayonet pins 805 is located on the guide groove 808, and the other side bayonet pins 805 are located at the bottom of the arc groove 905. The diameter of the bayonet pin 805 is greater than the width of the guide groove 808 and the arc groove 905, so as to limit the distance between the toothed disc 904 and the positioning disc 806. One side of the lifting plate 6 is fixed to the adjustment plate 8, and the adjustment frames 802 are fixedly arranged on both sides of the adjustment plate 8. A servo motor 803 is fixedly arranged at one end of the adjustment frame 802, and the other end is fixedly connected to the positioning rod 9. A gear 804 meshing with the toothed disc 904 is fixedly arranged at the driving end of the servo motor 803; it can be explained that when adjusting the position of the clamping seat 801, the servo motor 803 is started to drive the gear 804 to rotate, and the gear 804 can synchronously drive the toothed disc 904 to rotate, and the pin shaft 809 can synchronously move along the guide groove 808 under the limiting action of the arc groove 905, thereby adjusting the clamping seats 801 to gather or spread together.

[0074] In addition, in this embodiment, as the sealing ring 201, the upper plastic 202 and the steel ring 203 are grasped, the grasping height of each clamping seat 801 needs to be adjusted in real time during the grasping process. Fig.10 A detection disk 901 is fixedly arranged at the bottom of the positioning rod 9, and three groups of detection rods 902 are arranged in a circumferential array on the outer edge of the detection disk 901. Infrared sensors 903 are arranged at the ends of the detection rods 902 to detect their relative positions with the sealing ring 201, the upper plastic 202 and the steel ring 203; it can be explained that when grasping, the relative distance between the clamping seat 801 and each component can be obtained through the infrared sensor 903, and then the relative position between each clamping seat 801 and the component can be adjusted by the lifting cylinder 503 to facilitate grasping of the component.

[0075] It should also be noted that the grasped components are transferred to the top of the structural column 205. As the clamping seats 801 gather together, the components can fall under the action of gravity and be sleeved on the structural column 205 to achieve assembly.

[0076] For further information, see Fig.11 , a riveting cylinder 504 is also fixedly arranged on one side of the translation bracket 501, and the driving end of the riveting cylinder 504 is fixed to the riveting plate 505, and riveting die seats 506 are fixedly arranged on both sides of the riveting plate 505; specifically, when the assembly of various components is completed, the translation mechanism 501 moves the riveting cylinder 504 to the top cover body 1, and the riveting cylinder 504 drives the riveting plate 505 and the riveting die seat 506 to move downward to fold the annular riveting part 206 outward to preliminarily fix the various components, and finally the assembled top cover body 1 is transferred by the manipulator and the annular riveting part 206 is flattened by the stamping mechanism.

[0077] An assembly method for an assembly device of a square flip riveted top cover structure comprises the following steps:

[0078] See also Figure 6-Figure 7 as well as Fig.11 , several groups of top cover bodies 1 are stacked vertically and placed on the first loading part 301, several groups of pole bodies 2 are stacked vertically and placed on the second loading part 302, several groups of sealing rings 201 are arranged at the third loading part 304, several groups of upper plastics 202 are arranged at the fourth loading part 305, and several groups of steel rings 203 are arranged at the fifth loading part 306;

[0079] Firstly, the sealing ring 201 is grasped by the grasping mechanism, and the sealing ring 201 is transferred to the second loading part 302 by the translation mechanism 501, and the sealing ring 201 is sleeved on the structural column 205;

[0080] The pushing cylinder 4 drives the pushing seat 401 to move horizontally toward the second loading part 302, and the pushing seat 401 pushes the top cover body 1 to the top of the second loading part 302. The adjustment mechanism drives the clamping plates 7 on both sides to separate from the base 204. The second spring 403 can drive the second bearing frame 405 to move upward by a distance of the thickness of the pole body 2 under the action of the elastic force, so that the structural column 205 is embedded in the pole hole 103;

[0081] The upper plastic 202 and the steel ring 203 are sequentially sleeved on the structural column 205 by the cooperation of the grabbing mechanism and the translation mechanism 501 to achieve assembly;

[0082] After the assembly is completed, the translation mechanism 501 moves the riveting cylinder 504 to the top cover body 1. The riveting cylinder 504 drives the riveting plate 505 and the riveting die base 506 to move downward to fold the annular riveted part 206 outward to preliminarily fix the components. Finally, the assembled top cover body 1 is transferred by the robot and the annular riveted part 206 is flattened by the stamping mechanism.
