Description

Technical Field

[0001] This utility model belongs to the field of battery casing production, and specifically relates to a battery casing feeding device. Background Technology

[0002] The battery casing needs to pass through during the production process. Figure 1 The U-shaped part 8 before bending is processed into a square ring-shaped battery case 9 that can be broken open at the bottom. Specifically, the battery case 9 includes an upper top plate 91, left and right side plates 92, and a bottom plate 93 that is symmetrically arranged on the left and right sides. There is a small gap between the bottom plates 93, so that the deformation of the side plates 92 can change the size of the gap between the two bottom plates 93.

[0003] The support bracket 2 used to support the battery casing during stamping and bending includes an upper support beam 23 and lower support feet 24 located at both ends of the upper support beam 23. After stamping and bending, due to the presence of the bottom plate 93, the battery casing 9 is interfered with by the lower support feet 24 on both sides along the length of the upper support beam 23 and cannot be directly removed from the support bracket 2.

[0004] like Figure 2 As shown, in order to remove the battery case 9 from the support bracket 2, the side plate 92 of the case is usually pried open manually to increase the gap between the two bottom plates 93 of the case, forming a separation opening 94. Then the battery case 9 is lifted upwards so that the battery case 9 can be removed from the upper support beam 23 through the separation opening 94. However, the manual disassembly method is inefficient and greatly affects the production efficiency. Utility Model Content

[0051] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0052] like Figures 3-6 As shown, this utility model discloses a battery casing feeding device for feeding... Figure 1 , 2 The battery casing 9 shown is used for transmission.

[0053] Specifically, including:

[0054] The frame 1 consists of a platform 11 and a U-shaped beam 12. Bending station 13 and transition station 14 are arranged from right to left along the upper edge of the frame 1.

[0055] Support bracket 2 is set at bending station 13. Support bracket 2 includes an upper support beam 23 with the length direction along the left and right direction and the width direction along the front and back direction, a first support foot 21 set at the right end of the upper support beam 23, and a second support foot 22 set at the left end of the upper support beam 23.

[0056] The first feeding device 3 is used to transfer the battery casing 9 on the bending station 13 to the transition station 14.

[0057] Specifically, the first feeding device 3 includes:

[0058] The first feeding slide frame 31 is mounted on the platform 11 by means of a slide rail and a slider to slide in the left and right directions.

[0059] The first feeding driver 32, specifically, uses a combination of servo motor, lead screw and nut to connect the first feeding slide frame 31 and the platform 11, so that the operation of the first feeding driver 32 can drive the first feeding slide frame 31 to slide back and forth in the left and right directions.

[0060] The first feeding pusher 33 has two parts. The two first feeding pushers 33 are located on the front and rear sides of the upper support beam 23, and the two first feeding pushers 33 are provided with a left-facing plane to ensure contact with the battery case 9 when pushing the battery case 9.

[0061] There are two flared support plates 34. The two flared support plates 34 are located on the front and rear sides of the upper support beam 23. The right end of each flared support plate 34 is connected to the side of the first feeding pusher 33 that is close to each other, and the other end extends to the left. The thickness direction of the flared support plate 34 is along the front and rear direction, so that the first feeding pusher 33 and the flared support plate 34 are combined to form an L-shaped part.

[0062] The flared support plate 34 opens the shell side plate 92 on the support bracket 2 to form a separation opening 94 between the two shell bottom plates 93. The front and rear width of the separation opening 94 is greater than the width of the first support foot 21 in the front and rear direction. The first feeding slide frame 31 slides so that the first feeding pusher 33 pushes the battery shell 9 from the bending station 13 to the transition station 14.

[0063] Therefore, the U-shaped part 8 that needs to be bent is placed on top of the upper support beam 23, the flared support plate 34 is located on the front and rear sides of the upper support beam 23, and the first feeding pusher 33 is located on the right side of the U-shaped part 8, so that during the process of bending the U-shaped part 8 downward to form the battery case 9, the first feeding pusher 33 will not interfere with the battery case 9, while the flared support plate 34 restricts the flipping of the middle of the height of the side plate 92, so that the two bottom plates 93 of the case remain separated by the opening 94. Then the first feeding driver 32 works to drive the first feeding slide frame 31 to slide to the left. The first feeding pusher 33, which slides to the left, pushes the middle of the right side of the two side plates 92 of the case to the left, so that the battery case 9 is transferred from the bending station 13 to the transition station 14. During the transfer, due to the existence of the separation opening 94, the bottom plate 93 of the case will not interfere with the first support foot 21, so that the battery case 9 can be smoothly unloaded from the support bracket 2.

[0064] After the battery case 9 is unloaded from the support bracket 2, it can be removed manually by turning it to the left, or it can be further automated by the following method.

[0065] In addition, such as Figures 7-8 As shown, this embodiment also includes:

[0066] Track beam 4 is set at transition station 14. The track direction of track beam 4 is along the left and right direction. A first transition position 41 is set at the right position of track beam 4. The first feeding pusher 33 is used to push the battery case 9 from bending station 13 to the first transition position 41.

[0067] The fixing structure 5 is set at the transition station 14. The fixing structure 5 is used to fix the battery case 9 of the first transition station 41 to the track beam 4 so that the flared support plate 34 separates from the battery case 9 during the process of the first feeding sliding frame 31 retracting to the bending station 13.

[0068] Therefore, after the battery case 9 is transferred to the first transition position 41, the battery case 9 and the track beam 4 are fixed by the fixing structure 5. The first feeding driver 32 can drive the first feeding sliding frame 31 to slide to the right. During the sliding process, the friction between the shell side plate 92 and the flared support plate 34 is overcome to prevent the battery case 9 from being pulled back to the bending station 13 to the right.

[0069] Specifically, the fixing structure 5 includes a first lifting power component 51, a first pressing component 52 disposed on the first lifting power component 51, a second lifting power component 53, and a second pressing component 54 disposed on the second lifting power component 53. The first lifting power component 51 is used to drive the first pressing component 52 downward to press the right end of the shell top plate 91 of the first transition position 41 onto the track beam 4. The second lifting power component 53 is used to drive the second pressing component 54 downward to press the left end of the shell top plate 91 of the first transition position 41 onto the track beam 4, thereby achieving stable fixing.

[0070] Specifically, a first L-shaped mounting bracket 55 is provided on the left side of the middle part of the U-shaped beam 12. The horizontal free end of the first L-shaped mounting bracket 55 is fixed to the U-shaped beam 12, and the vertical free end of the first L-shaped mounting bracket 55 extends downward and is used for the fixed installation of the first lifting power component 51.

[0071] Specifically, a second L-shaped mounting bracket 56 is provided on the platform 11. The vertical free end of the second L-shaped mounting bracket 56 is fixed to the platform 11 with its vertical free end facing downwards. The horizontal free end of the first L-shaped mounting bracket 55 extends backwards and is used for the fixed installation of the second lifting power component 53.

[0072] Preferably, the first lifting power component 51 and the second lifting power component 53 are cylinders, the first pressing component 52 is fixed on the output shaft of the first lifting power component 51, and the second pressing component 54 is fixed on the output shaft of the second lifting power component 53, so that the operation is faster and the production efficiency is improved.

[0073] In addition, a marking device 57 is included. The marking device 57 is located above the first transition position 41. The marking device 57 is used to mark the upper surface of the shell top plate 91 of the first transition position 41. Therefore, after the fixing structure 5 fixes the battery shell 9 to the track beam 4 and the flared support plate 34 retracts, the shell side plate 92 is reset to make the shell top plate 91 flatter. Then the marking device 57 marks the top surface of the shell top plate 91 to make the printed graphics and text flatter.

[0074] In addition, such as Figure 9 As shown, the track beam 4 is located at the left end of the first transition position 41 and a second transition position 42 is provided; the first feeding device 3 also includes a second moving power component 35 and a second feeding pusher 36. Specifically, the second moving power component 35 is a cylinder, the cylinder body of the second moving power component 35 is fixedly installed on the first feeding sliding frame 31, and the second feeding pusher 36 is fixedly installed on the output shaft of the second moving power component 35 so that the second feeding pusher 36 is driven to slide in the front and back direction by the second moving power component 35.

[0075] When the second feeding pusher 36 is located at the first transition position 41, the second moving power member 35 drives the second feeding pusher 36 to slide, so that the second feeding pusher 36 and the battery case 9 located at the first transition position 41 are in an interference arrangement in the left and right direction.

[0076] When the second feeding pusher 36 is located at the second transition position 42, the second moving power member 35 drives the second feeding pusher 36 to slide so that the second feeding pusher 36 and the battery case 9 located at the first transition position 41 are arranged in a non-interfering manner in the left and right direction.

[0077] Therefore, the battery casing 9, which has been marked at the first transition position 41, is pushed to the second transition position 42 by the second feeding pusher 36 for subsequent unloading.

[0078] Preferably, there are two of each of the second moving power component 35 and the second feeding pusher 36, and the two sets of the second moving power component 35 and the second feeding pusher 36 are located on the front and rear sides of the track beam 4; wherein, each of the second feeding pushers 36 includes a clamping part 361 and a pushing part 362 to make the second feeding pusher 36 L-shaped, the two clamping parts 361 are used to clamp the battery case 9 in the front and rear direction to position the battery case 9 in the front and rear direction, and the two pushing parts 362 are used to push the side of the battery case 9 located at the first transition position 41 toward the bending position 13.

[0079] Therefore, under the action of the two second feeding pushers 36, the front and rear sides of the battery case 9 are clamped and positioned, and the battery case is pushed and transported to the left.

[0080] In addition, such as Figure 10As shown, the frame 1 is located on the side of the transition station 14 away from the bending station 13, and a material unloading station 15 is provided; correspondingly, a second feeding device 6 is also included, which is used to transfer the battery case 9 on the second transition station 42 to the material unloading station 15; specifically, the second feeding device 6 includes:

[0081] The second feeding slide frame 61 is slidably mounted on the frame 1 in the left and right directions;

[0082] The second feeding driver 62, specifically, uses a combination of servo motor, lead screw and nut to connect the second feeding slide frame 61 and the platform 11, so that the second feeding driver 62 works to drive the second feeding slide frame 61 to slide back and forth.

[0083] The tilting frame 63 is rotatably mounted on the second feeding slide frame 61, and the tilting frame 63 is arranged in the front-back direction relative to the rotation axis of the second feeding slide frame 61.

[0084] The flip drive 64 uses a combination of servo motor and reducer to connect the flip frame 63 and the second feeding slide frame 61, so that the flip drive 64 works to drive the flip frame 63 to flip back and forth.

[0085] There are two sets of clamping suction cups 65, both sets of clamping suction cups 65 are set on the flipping frame 63, and the two sets of clamping suction cups 65 are arranged opposite each other in the front-back direction.

[0086] Therefore, when the battery case 9 is in the second transition position 42, the front and rear side plates 92 are subjected to negative pressure adsorption by the clamping suction cups 65 on both sides. By setting the spacing of the clamping suction cups 65 on both sides, when the clamping suction cups 65 adsorb, a certain deformation and bending is formed between the two side plates 92, so that the two bottom plates 93 of the case remain separated from each other and form a separation opening 94 with a front-to-back width greater than the front-to-back width of the track beam 4. Then, the flipping driver 64 works to flip the flipping frame 63 together with the clamping suction cups 65 and the battery case 9 by 180°, so that the battery case 9 is dislodged from the track beam 4 during the flipping process. During the flipping process, the second feeding driver 62 performs the sliding drive of the second feeding sliding frame 61 to transport the battery case 9 to the unloading station 15 to the left for unloading.

[0087] Preferably, this embodiment also includes an expansion member 43, which is fixedly mounted on the vertical rod below the second transition position 42 by means of bolts or the like. The expansion member 43 includes a retaining column portion 431 in the shape of a quadrangular prism and a guide cone portion 432 in the shape of a triangular prism, with the guide cone portion 432 located to the right of the retaining column portion 431.

[0088] Therefore, during the process of the battery case 9 being transferred from the first transition position 41 to the second transition position 42, the two bottom plates 93 first approach and contact the tip of the guide cone 432, and under the action of the guide cone 432, the two bottom plates 93 are separated from each other, gradually increasing the separation opening 94; then the left end of the bottom plate 93 completely passes over the guide cone 432 and is kept in place by the holding post 431. Due to the opening of the separation opening 94, the side plate 92 has a certain outward deformation, which makes it easier to adsorb the suction cup 65 and improves the smoothness.

[0089] This embodiment also includes a feeding conveyor belt 7, which is set at the feeding station 15 and is used to output the battery casing 9 to the left. It should be noted that the battery casing 9 is flipped so that the top plate 91 faces down and the bottom plate 93 faces up, thus making the transmission on the feeding conveyor belt 7 smoother.

[0090] The feeding conveyor belt 7 is driven by a motor, transmission rollers and other structures, which will not be described in detail here.

[0091] In addition, this embodiment also includes two sets of guide roller assemblies 71. The two sets of guide roller assemblies 71 are located on both sides of the width (front and rear) of the unloading conveyor belt 7. Each guide roller assembly 71 includes a guide roller frame 711 and rotating guide rollers 712 arranged on the guide roller frame 711 in the left and right direction. The rotation axis of each rotating guide roller 712 relative to the guide roller frame 711 is arranged vertically.

[0092] Therefore, the battery casing 9 placed on the feeding conveyor belt 7 is output more stably under the action of the guide roller assemblies 71 on both sides.

[0093] In addition, the first feeding sliding frame 31 includes a first base 311, two first adjustment frames 312 that are slidably mounted on the first base 311 in the front-back direction, and a first adjustment driver 313 for driving the two first adjustment frames 312 to slide and adjust. The two sets of first feeding pushers 33 and flared support plates 34 are disposed on different first adjustment frames 312, so that they can be adjusted by the first adjustment driver 313 to adapt to battery cases 9 of different specifications.

[0094] In addition, the flip frame 63 includes a second base 631, two second adjustment frames 632 that are slidably mounted on the second base 631 in the front-back direction, and a second adjustment driver 633 for driving the two second adjustment frames 632 to slide and adjust. Two sets of clamping suction cups 65 are disposed on different second adjustment frames 632, so that they can be adjusted by the second adjustment driver 633 to adapt to battery cases 9 of different specifications.

[0095] Specifically, both the first adjustment driver 313 and the second adjustment driver 633 adopt a combination of servo motor, lead screw and nut.

[0096] In this embodiment, the left-right direction is defined as the first direction, and the front-back direction is defined as the second direction.

[0097] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
