Description

Technical Field

[0001] This utility model belongs to the field of battery casing spraying equipment, and specifically relates to a battery casing loading and unloading device. Background Technology

[0002] As a critical protective carrier for the battery, the performance of the battery casing directly affects the battery's safety, stability, and lifespan. Therefore, it must possess excellent corrosion resistance, insulation properties, and structural strength. To meet these core performance requirements, the industry commonly employs a process of spraying a coating onto the contact surface between the battery casing and the top cover. By forming a uniform and dense coating on this contact surface, the overall performance of the battery casing is significantly improved, ensuring the sealing reliability and long-term stability of the assembled battery.

[0003] In the above-mentioned spraying process, there are strict requirements for controlling the spraying area: the surfaces on the battery case that do not need to be sprayed must be strictly sealed and shielded, and only the contact surfaces to be sprayed must be exposed to ensure that the sprayed coating is precisely deposited on the target area, and to avoid problems such as reduced assembly accuracy or sealing failure due to coating coverage on the surfaces that do not need to be sprayed.

[0004] Currently, the masking structures used in battery casing spraying mainly adopt a split design, including an upper masking component and a lower masking component. During use, the battery casing is wrapped between the upper and lower masking components, and their cooperation achieves a sealed masking of non-target areas. The specific process flow is as follows: First, the lower masking component is placed on a skid; then, the battery casing is inverted and positioned on the lower masking component; finally, the upper masking component is fastened to complete the masking. The skid then transports the masked battery casing to the spraying station for spraying. After spraying, the upper masking component is removed first, then the battery casing is taken out from the lower masking component and transferred to a drying skid for subsequent drying and curing operations.

[0005] However, existing shielding structures and corresponding loading and unloading methods have significant technical defects: because the battery case is positioned upside down on the lower shielding component, after the coating is completed, the contact surface between the battery case and the lower shielding component is prone to sticking firmly due to the adhesion of the coating, air pressure adsorption, or tight positioning fit. This makes it difficult to remove the battery case from the lower shielding component, requiring additional force and potentially causing scratches, peeling, or deformation of the coated coating during removal, affecting the integrity and uniformity of the coating and reducing the product qualification rate. Furthermore, manual or simple mechanical removal methods are inefficient, cumbersome, and difficult to adapt to the pace requirements of large-scale production. In addition, during the process of transferring the battery case from the lower shielding component to the drying skid, there is a lack of stable load-bearing and transfer mechanisms, which can easily cause the battery case to be bumped or the coating to be damaged secondary. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0034] A battery casing loading and unloading device includes a skid 1, a lifting seat 2, a main body fixing mechanism 3, a translation frame 4, and a workpiece clamping mechanism 5, such as... Figure 1 As shown, the skid 1 is used to support the lower shield, the battery case and the upper shield. The skid 1 is provided with a support plate 11 for supporting the lower shield. The support plate 11 and the lower shield are provided with corresponding through holes 12.

[0035] Lifting bracket 2 is used to lift the battery casing, separating it from the lower shield, such as... Figure 2As shown, a cylinder 21 is provided on one side of the lifting seat 2, and a push rod 22 is connected to the piston rod of the cylinder 21. The push rod 22 is positioned corresponding to the through hole 12. After the skid 1 carries the battery case to the working position of the push rod 22, the push rod 22 rises and passes through the through hole 12 to lift the battery case to a certain height, thus completing the separation of the battery case from the lower shield.

[0036] like Figure 3 , Figure 4 As shown, the main fixing mechanism 3 includes a fixing frame 31 for mounting the workpiece clamping mechanism 5 and the translation frame 4.

[0037] like Figure 6 , Figure 7 As shown, the translation frame 4 is installed on the fixed frame 31. The upper end of the translation frame 4 is provided with a slide 41, and the slide 41 is provided with a translation drive mechanism for driving the translation frame 4 to translate on the fixed frame 31 and transferring the battery case on the skid 1 to the drying skid.

[0038] like Figure 8 , Figures 10-11 As shown, the workpiece clamping mechanism 5 is installed on one side of the translation frame 4 for gripping and transferring battery casings. It includes a clamping seat 51, clamping arms 52 disposed at both ends of the clamping seat 51, a clamping drive mechanism for driving the clamping arms 52 to open and close, and a claw assembly 54 disposed at the lower end of the clamping arms 52. The claw assembly 54 includes a claw base 541, with claw arms 542 connected to both sides of the claw base 541. One end of the claw arm 542 is provided with a column 544, and the upper end of the column 544 is connected with a support column 546. The clamping seat 51 is also provided with a lifting drive mechanism for driving the workpiece clamping mechanism 5 to move up and down longitudinally along the translation frame 4.

[0039] like Figure 4 , Figures 6-7 As shown, the translation drive mechanism includes translation slide rails 32 fixedly installed on both sides of the fixed frame 31. Translation sliders 45 are provided on both sides of the lower part of the translation frame 4, which slide in cooperation with the translation slide rails 32. A translation motor 42 and a translation reducer 43 are installed on the translation frame 4. A translation gear 44 is connected to the output shaft of the translation reducer 43. A translation rack 33 is provided in the middle of the fixed frame 31. The translation gear 44 meshes with the translation rack 33.

[0040] After the workpiece clamping mechanism 5 removes the battery case, the translation drive mechanism starts. The translation motor 42 and the translation reducer 43 rotate, driving the translation gear 44 to rotate. The translation gear 44 meshes with the translation rack 33, driving the translation frame 4 and the workpiece clamping mechanism 5 to move on the fixed frame 31, thus realizing the transfer of the battery case to the drying skid.

[0041] like Figure 8 , Figure 10As shown, the clamping drive mechanism includes a clamping motor 55 and a clamping reducer fixedly installed on both sides of the clamping seat 51. A clamping gear 56 is installed on the output shaft of the clamping reducer. A clamping slide rail 58 is provided at the lower part of the clamping seat 51. A clamping slider that slides with the clamping slide rail 58 is provided at the upper end of the clamping arm 52. An extension arm is also provided on one side of the clamping arm 52. A clamping rack 57 is fixedly connected to the extension arm. The clamping gear 56 meshes with the clamping rack 57.

[0042] Before the battery case is removed, the clamping arm 52 is in the open state. When the battery case is removed, the clamping motors 55 on both sides rotate, which drives the clamping gear 56 to rotate through the clamping reducer. This causes the clamping rack 57 and the clamping arm 52 to move closer to each other, so that the two claw assemblies 54 are tightened inward to support the battery case. After the top rod 22 retracts, the battery case falls on the claw assembly 54, completing the loading of the battery case.

[0043] like Figure 6 , Figure 8 , Figure 10 As shown, the lifting drive mechanism includes a lifting motor 59 and a lifting reducer installed on the upper part of the clamping seat 51. A lifting gear 510 is installed on the output shaft of the lifting reducer. Lifting sliders 511 are provided on both sides of the clamping seat 51. A lifting guide rail 46 that slides with the lifting slider 511 is provided on one side of the translation frame 4. A lifting rack 47 is also provided on the side of the translation frame 4. The lifting rack 47 meshes with the lifting gear 510.

[0044] After the claw assembly 54 removes the battery case, the top rod 22 retracts, and the translation frame 4 moves horizontally on the fixed frame 31, transferring the battery case to the top of the drying skid. The lifting drive mechanism is activated, driving the clamping seat 51 to move downward along the translation frame 4, placing the battery case on the drying skid. The claw assembly 54 continues to descend a certain distance, so that the upper end of the support column 546 is lower than the lower surface of the battery case. Then, the clamping motor 55 drives the clamping arm 52 to move to both sides of the battery case, separating the clamping arm 52 from the battery case. Then, it returns along the same path to clamp the next battery case.

[0045] like Figure 5 As shown, limit switches 34 are provided at both ends of the translation slide rail 32 and the clamping slide rail 58 to limit the movement range of the translation frame 4 and the clamping arm 52, and to prevent the translation frame 4 and the clamping arm 52 from falling out of the limit.

[0046] like Figure 8 , Figure 11As shown, the claw base 541 has a second mounting plate 547 in the middle, and the second mounting plate 547 has a plurality of screws 548. The lower end of the arm 52 has a first mounting plate, and the first mounting plate has a plurality of through holes 12 corresponding to the positions of the screws 548. Each screw 548 has two sets of nuts, and the two sets of nuts are located on the upper and lower sides of the first mounting plate, respectively, so as to facilitate the adjustment of the height of the claw assembly 54.

[0047] like Figure 8 , Figure 9 As shown, the claw base 541 is provided with diagonal braces 53 on both sides. The upper end of the diagonal brace 53 is connected to the arm 52 through the connecting plate 531, which enhances the stability of the connection between the claw assembly 54 and the arm 52. The connecting plate 531 is provided with a long waist groove 532 to accommodate the height adjustment of the claw assembly 54.

[0048] like Figure 11 As shown, the upper end of the column 544 is provided with a stud 545, and the support column 546 is threadedly connected to the stud 545, which is used to finely adjust the height of the support column 546 and ensure the stability of the support column 546 in supporting the battery case.

[0049] like Figure 11 As shown, the claw base 541 and the claw arm 542 are both made of profiles with slots. The claw arm 542 is connected to the claw base 541 through several connecting corner pieces 543, which are used to adjust the position of the claw arm 542 extending out of the claw base 541, thereby adjusting the support position of the support column 546 on the battery case. It is suitable for loading and unloading battery cases of different specifications.

[0050] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the scope defined by the structure of this utility model, they should all fall within the protection scope of this utility model.
