Technical Field

[0001] This utility model relates to the field of leveling technology, and in particular to a leveling device. Background Technology

[0002] During the manufacturing process of new energy vehicle batteries, the flatness of the positive and negative electrode covers changes due to stamping, riveting, and welding processes, thus affecting the splicing and welding of the positive and negative electrode covers with the casing. Related technologies typically include testing equipment in the production line to inspect the flatness of the battery's positive and negative electrode covers. Those failing the flatness test are treated as defective products and manually leveled and reworked, thereby reducing the leveling efficiency of the battery's positive and negative electrode covers. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a leveling device that can improve leveling efficiency.

[0004] A leveling device according to an embodiment of the present invention includes a frame, a bearing module, a detection module, and a leveling module. The bearing module is mounted on the frame and has a bearing surface with a clearance channel. The bearing surface is used to bear a workpiece. The detection module is mounted on the frame and is used to detect the flatness of the workpiece on the bearing surface. The leveling module is mounted on the frame and is used to level the workpiece on the bearing surface. The leveling module includes a limiting structure, a first leveling structure, and a second leveling structure. The limiting structure is used to limit the workpiece in the vertical direction in conjunction with the bearing surface. The first leveling structure and the second leveling structure are respectively located on the lower and upper sides of the bearing surface and are both electrically connected to the detection module. When the detection module detects that the workpiece is in a concave flat state, the first leveling structure can at least partially pass upward through the clearance channel to level the workpiece. When the detection module detects that the workpiece is in a convex flat state, the second leveling structure can level the workpiece downward.

[0005] A leveling device according to an embodiment of the present utility model has at least the following technical effects:

[0006] In the operation of the leveling equipment of this application, the workpiece is first placed on the bearing surface of the bearing module, and then the workpiece on the bearing surface is detected by the detection module. When the detection module detects that the workpiece is in a convex flat state, the workpiece on the bearing surface is leveled downward by the second leveling structure located on the upper side of the bearing surface. When the detection module detects that the workpiece on the bearing surface is in a concave flat state, the limiting structure can limit the upper surface of the workpiece, and then the first leveling structure located on the lower side of the bearing surface passes upward through the avoidance channel to level the workpiece upward. In the leveling equipment of this application, the flatness of the workpiece is detected by the detection module to determine whether the workpiece is in a convex or concave flatness state. This allows for the selective use of a first leveling structure or a second leveling structure to level the workpiece. When the workpiece is in a convex flatness state, it is leveled by the cooperation of the second leveling structure and the bearing module. When the workpiece is in a concave flatness state, it is leveled by the cooperation of the first leveling structure and the limiting structure. Thus, the leveling equipment of this application can adaptively level the workpiece according to its flatness state, resulting in higher leveling efficiency.

[0011] According to some embodiments of the present invention, a leveling device is provided, wherein the first positioning groove and the second positioning groove are both through grooves extending along the first horizontal direction, and a positioning structure is provided on the opposite side of the first bearing seat and the second bearing seat.

[0012] According to some embodiments of the present invention, a leveling device includes a leveling module comprising two limiting structures distributed along a first horizontal direction.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figures 1 to 4 A leveling device according to an embodiment of the present utility model will be described in detail.

[0033] refer to Figures 1 to 3 A leveling device according to an embodiment of the present invention includes a frame 100, a bearing module 200, a detection module 300, and a leveling module 400. The bearing module 200 is disposed on the frame 100, and a bearing surface 200a is provided on the bearing module 200. An obstacle avoidance channel 200b is provided on the bearing surface 200a, and the bearing surface 200a is used to bear a workpiece. The detection module 300 is disposed on the frame 100 and is used to detect the flatness of the workpiece on the bearing surface 200a. The leveling module 400 is disposed on the frame 100 and is used to level the workpiece on the bearing surface 200a. The leveling module 400 includes a limiting structure 41. 0. The first leveling structure 420 and the second leveling structure 430, and the limiting structure 410 are used to limit the workpiece in the vertical direction in conjunction with the bearing surface 200a. The first leveling structure 420 and the second leveling structure 430 are respectively located on the lower side and the upper side of the bearing surface 200a, and are both electrically connected to the detection module 300. When the detection module 300 detects that the workpiece is in a concave flat state, the first leveling structure 420 can at least partially pass upward through the avoidance channel 200b to level the workpiece. When the detection module 300 detects that the workpiece is in a convex flat state, the second leveling structure 430 can level the workpiece downward.

[0034] In the operation of the leveling equipment of this application, the workpiece is first placed on the bearing surface 200a of the bearing module 200. Then, the workpiece on the bearing surface 200a is detected by the detection module 300. When the detection module 300 detects that the workpiece is in a convex flat state, the workpiece on the bearing surface 200a is leveled downward by the second leveling structure 430 located on the upper side of the bearing surface 200a. When the detection module 300 detects that the workpiece on the bearing surface 200a is in a concave flat state, the limiting structure 410 can limit the upper surface of the workpiece. Then, the workpiece is leveled upward by the first leveling structure 420 located on the lower side of the bearing surface 200a passing through the avoidance channel 200b.

[0035] As can be seen from the above working process, in the leveling equipment of this application, the flatness state of the workpiece is detected by the detection module 300 to determine whether the workpiece is in a convex or concave flatness state. This allows for the selective use of the first leveling structure 420 or the second leveling structure 430 to level the workpiece. When the workpiece is in a convex flatness state, it is leveled by the cooperation of the second leveling structure 430 and the bearing module 200. When the workpiece is in a concave flatness state, it is leveled by the cooperation of the first leveling structure 420 and the limiting structure 410. Thus, the leveling equipment of this application can adaptively level the workpiece according to its flatness state, resulting in higher leveling efficiency.

[0036] Specifically, the detection module 300 includes a 3D line laser measuring instrument, which is electrically connected to the first leveling structure 420 and the second leveling structure 430 respectively.

[0037] Understandably, 3D line laser measuring instruments determine whether a workpiece is in a convex or concave flat state by detecting the flatness of its surface. 3D line laser measuring instruments have a faster detection speed and higher detection accuracy.

[0038] It should be noted that, in addition to using a 3D line laser measuring instrument, the detection module 300 can also be equipped with other detection structures capable of detecting the flatness of the workpiece surface, such as a CCD camera.

[0039] refer to Figure 2 and Figure 4In some embodiments of this utility model, the bearing module 200 includes a first bearing seat 210 and a second bearing seat 220 distributed along a first horizontal direction. A first positioning groove 211 and a second positioning groove 221 are respectively formed on the first bearing seat 210 and the second bearing seat 220. The first positioning groove 211 and the second positioning groove 221 are respectively used to accommodate workpieces at opposite ends in the first horizontal direction. The bottom surfaces of the first positioning groove 211 and the second positioning groove 221 together form a bearing surface 200a. An avoidance channel 200b is defined between the first bearing seat 210 and the second bearing seat 220.

[0040] Understandably, by placing the workpiece at its opposite ends in the first positioning groove 211 of the first support 210 and the second positioning groove 221 of the second support 220, the workpiece can be initially positioned. The bearing surface 200a formed by the bottom surfaces of the first and second positioning grooves 211 and 221 can support the workpiece at its opposite ends in the first horizontal direction. When the second leveling structure 430 needs to level the convex workpiece, it can apply a downward force to the middle area of ​​the workpiece. At this time, the bottom surface of the first positioning groove 211 can cooperate with the bottom surface of the second positioning groove 221 to provide upward support for the workpiece, so as to cooperate with the second leveling structure 430 to smoothly complete the leveling of the workpiece; the arrangement of the first bearing seat 210 and the second bearing seat 220 can limit the formation of a clearance channel 200b between the first bearing seat 210 and the second bearing seat 220, so that the first leveling structure 420 can pass upward through the clearance channel 200b to apply an upward force to the middle area of ​​the workpiece, thereby realizing the leveling of the workpiece in the concave flat state.

[0041] like Figure 2 and Figure 4 As shown, in some embodiments, at least one of the first support 210 and the second support 220 is positionally adjustable along a first horizontal direction.

[0042] It is understandable that by adjusting the relative positions of the first bearing seat 210 and the second bearing seat 220 in the first horizontal direction, the first bearing seat 210 and the second bearing seat 220 can cooperate to support workpieces of different sizes and specifications.

[0043] It is understandable that by adjusting the position of the first bearing seat 210 and / or the second bearing seat 220, the bearing position of the workpiece can be changed, thereby adjusting the force state when the second leveling structure 430 levels the workpiece in the convex state, and thus adjusting the leveling effect of the second leveling structure 430.

[0044] like Figure 2 and Figure 4As shown, in one embodiment, the carrier module 200 further includes a mounting base 230, a first driver 240, and a conveyor belt 250. The first carrier base 210 and the second carrier base 220 are both slidably disposed on the mounting base 230 along a first horizontal direction. The first driver 240 is drivenly connected to the conveyor belt 250 and can drive the conveyor belt 250 to move along a circular track. The conveyor belt 250 has a first segment 251 and a second segment 252 that move in opposite directions along the first horizontal direction. The first segment 251 is connected to the first carrier base 210, and the second segment 252 is connected to the second carrier base 220.

[0045] Understandably, the first driver 240 drives the conveyor belt 250 to move along a circular track, enabling the first segment 251 and the second segment 252 of the conveyor belt 250 to move in opposite directions in the first horizontal direction. When the first driver 240 drives the conveyor belt 250 to rotate in the forward direction, the first segment 251 and the second segment 252 move closer to each other in the first horizontal direction. Driven by the first segment 251 and the second segment 252, the first support seat 210 and the second support seat 220 can move closer to each other synchronously, so that the position of the workpiece being supported moves closer to the middle area of ​​the workpiece. When the first driver 240 drives the conveyor belt 250 to rotate in the reverse direction, the first segment 251 and the second segment 252 move away from each other in the first horizontal direction. Driven by the first segment 251 and the second segment 252, the first support seat 210 and the second support seat 220 can move away from each other synchronously, so that the position of the workpiece being supported moves away from the middle area of ​​the workpiece.

[0046] Understandably, since the first driver 240 can drive the first carrier 210 and the second carrier 220 to move closer or further away in the first horizontal direction through the conveyor belt 250, the force on the workpiece in the first horizontal direction can always remain uniform during the position adjustment of the first carrier 210 and the second carrier 220 in the first horizontal direction. Correspondingly, the two ends of the workpiece in the first horizontal direction can be evenly and symmetrically distributed relative to the second leveling member 432, so that the force on the workpiece during shaping is more uniform.

[0047] Specifically, the mounting base 230 is provided with a first slide rail 231 and a second slide rail 232 that both extend along a first horizontal direction. The first support base 210 is slidably mounted on the first slide rail 231, and the second support base 220 is slidably mounted on the second slide rail 232.

[0048] refer to Figure 2 and Figure 3In some embodiments, the bearing module 200 further includes a plurality of positioning structures 260, each positioning structure 260 including a second driver 261 and a positioning member 262 connected to each other. The plurality of positioning members 262 are horizontally circumferentially distributed. The bearing surface 200a and the plurality of positioning members 262 define a workpiece positioning area 200c. The second driver 261 is configured to drive the positioning member 262 to approach and complete the positioning of the workpiece in the workpiece positioning area 200c before the leveling module 400 levels the workpiece, and to drive the positioning member 262 away from the workpiece in the workpiece positioning area 200c when the leveling module 400 levels the workpiece.

[0049] Understandably, by placing the workpiece in the workpiece positioning area 200c defined between multiple positioning elements 262 and the bearing surface 200a, in each positioning structure 260, the second driver 261 drives the positioning element 262 to approach the workpiece in the workpiece positioning area 200c to position the workpiece on the bearing module 200, so that the subsequent detection module 300 can accurately detect the flatness of the workpiece, and so that the subsequent first leveling structure 420 or second leveling structure 430 can accurately level the workpiece.

[0050] It is understandable that when the first leveling structure 420 or the second leveling structure 430 levels the workpiece, the horizontal dimension of the workpiece will increase due to its own deformation. Before the first leveling structure 420 or the second leveling structure 430 levels the workpiece, since the second driver 261 in each positioning structure 260 can drive the positioning member 262 away from the workpiece in the workpiece positioning area 200c, the probability of the workpiece interfering with the positioning structure 260 during the shaping process can be reduced.

[0051] like Figure 2 and Figure 3 As shown, in one embodiment, the first positioning groove 211 and the second positioning groove 221 are both through grooves extending along the first horizontal direction, and a positioning structure 260 is provided on the opposite side of the first support seat 210 and the second support seat 220.

[0052] It should be noted that the workpiece is a long strip extending along the first horizontal direction.

[0053] It is understandable that by placing the workpiece in the first positioning groove 211 and the second positioning groove 221, and then driving the positioning member 262 closer to the workpiece in the workpiece positioning area 200c by the second driver 261 in the two positioning structures 260, the position of the workpiece in the first horizontal direction is positioned. Before leveling the workpiece, the positioning member 262 is driven away from the workpiece in the workpiece positioning area 200c by the second driver 261, so as to reduce the probability of interference between the workpiece and the positioning structure 260 during the shaping process, thereby improving the leveling effect of the workpiece.

[0054] refer to Figure 1 and Figure 3 In some embodiments of this utility model, the leveling module 400 includes two limiting structures 410 distributed along a first horizontal direction. On the horizontal projection plane, the orthographic projection of the first leveling structure 420 is located between the orthographic projections of the two limiting structures 410. The limiting structure 410 includes a third driver 411 and a limiting member 412 connected to each other. The limiting member 412 is located on the upper side of the bearing surface 200a. The third driver 411 can drive the limiting member 412 to move downwards and abut against the upper surface of the workpiece.

[0055] It is understandable that the third driver 411 drives the connected limiting member 412 to move downward to abut against the upper surface of the workpiece on the bearing surface 200a. Then, the first leveling structure 420 levels the workpiece upward. At this time, the first leveling structure 420 applies an upward force to the middle area of ​​the workpiece. The setting of the two limiting structures 410 allows the two ends of the workpiece in the first horizontal direction to be respectively limited downward by the two limiting members 412. Thus, with the cooperation of the first leveling structure 420 and the two limiting structures 410, the workpiece in the concave flat state can be leveled.

[0056] refer to Figure 1 and 3 In some embodiments of this utility model, the first leveling structure 420 includes a fourth driver 421 and a first leveling component 422. The fourth driver 421 is positionally adjustable in the first horizontal direction and is drivenly connected to the first leveling component 422. When the detection module 300 detects that the workpiece on the bearing surface 200a is in a convex flat state, the fourth driver 421 can drive the first leveling component 422 upward through the avoidance channel 200b to level the workpiece on the bearing surface 200a.

[0057] It is understood that the first leveling member 422 is driven to move upward by the fourth driver 421 so that the first leveling member 422 passes through the clearance channel 200b and abuts against the workpiece on the bearing surface 200a, so as to apply an upward force in the middle area of ​​the workpiece, thereby achieving the leveling of the workpiece in the concave flat state.

[0058] Understandably, by adjusting the position of the fourth driver 421, the first leveling member 422 can be directly facing the clearance channel 200b, so that under the drive of the fourth driver 421, the first leveling member 422 can smoothly pass through the clearance channel 200b to abut the workpiece upward.

[0059] Specifically, the fourth actuator 421 is an electric cylinder, and the first leveling structure 420 includes a mounting plate 423 and a threaded connector. The fourth actuator 421 is connected to the mounting plate 423. The mounting plate 423 is provided with an elongated hole 423a extending in the first horizontal direction. The threaded connector is slidably passed through the elongated hole 423a. The mounting plate 423 is connected to the frame 100 through the threaded connector.

[0060] In some embodiments of this utility model, the second leveling structure 430 includes a fifth driver 431 and a second leveling component 432. The driving end of the fifth driver 431 is connected to the second leveling component 432. When the detection module 300 detects that the workpiece on the bearing surface 200a is in an upward convex state, the fifth driver 431 can drive the second leveling component 432 to move downward so as to press down and level the workpiece.

[0061] refer to Figure 1 In some embodiments of this utility model, the leveling device further includes a conveying track 500, which is connected to the bearing module 200 and can drive the bearing module 200 to move sequentially to the detection module 300 and the leveling module 400.

[0062] Understandably, in the operation of the leveling equipment of this application, the workpiece is first placed on the bearing surface 200a of the bearing module 200, and then the bearing module 200 is conveyed to the detection module 300 via the conveyor rail 500. The detection module 300 detects the flatness of the workpiece, and then the bearing module 200 is conveyed to the leveling module 400 via the conveyor rail 500. The leveling module 400 levels the workpiece, thereby achieving automatic leveling of the workpiece. By conveying the bearing module 200 sequentially to the detection module 300 and the leveling module 400 via the conveyor rail 500, the detection module 300 and the leveling module 400 can be spaced apart in the horizontal direction, thereby reducing the possibility of interference between the detection module 300 and the leveling module 400.

[0063] like Figure 1 As shown, in some embodiments, multiple conveying tracks 500 are provided in the horizontal direction, and each conveying track 500 is provided with a bearing module 200. The detection module 300 includes a detection structure 310 and a position adjustment structure 320. The detection structure 310 is used to detect the workpiece, and the position adjustment structure 320 is connected to the detection structure 310 and is used to drive the detection structure 310 to move between the various conveying tracks 500.

[0064] Understandably, the position adjustment structure 320 moves the detection structure 310 between each conveying track 500, allowing a single detection structure 310 to complete the detection of the flatness of the workpieces on multiple conveying tracks 500, thereby reducing the overall cost of the leveling equipment.

[0065] Specifically, the leveling equipment includes two conveying tracks 500 arranged side by side along the first horizontal direction. Each conveying track 500 is provided with a leveling module 400. The position adjustment structure 320 includes a motor, a slide rail and a slide block. The slide rail extends along the first horizontal direction. The slide block is connected to the detection structure 310. The motor can drive the slide block to slide on the slide rail, thereby driving the detection structure 310 to slide along the first horizontal direction.

[0066] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
