Description

Technical Field

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

[0002] During battery manufacturing, after the lower battery casing is machined, it needs to be transferred to a transfer trolley, which then moves it to the assembly station. Currently, a cylinder drives the gripper to move, clamping the casing against the side wall to complete the transport. Because there are tolerances in the length and width of the casing's dimensions, elastic elements, such as rubber-coated material pads, are installed at the clamping points between the gripper and the casing. These elastic elements accommodate casings of different sizes. However, the elastic range of the rubber-coated material is limited to only 10mm. When the casing's dimensions vary significantly, the existing gripper's clamping action becomes unstable. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0024] Reference Figure 1 and Figure 2As shown, a clamping device for a box according to the present invention includes: a support base 1; an adsorption assembly 3 including an adsorption element 35, wherein the support base 1 is connected to a support plate 11, and the adsorption element 35 is connected to the support plate 11; and a clamping assembly 2 including a driving element 24 and at least two clamping mechanisms arranged opposite to each other, wherein the clamping mechanisms arranged opposite to each other form a clamping space, the clamping mechanisms are slidably connected to the support base 1, the driving element 24 can drive the clamping mechanisms to move, the clamping mechanism includes a clamping element, the clamping element includes a first clamping plate 261, the planes of the first clamping plates 261 of the clamping mechanisms arranged opposite to each other are coplanar, and the adsorption end of the adsorption element 35 is located within the clamping space.

[0025] In this embodiment, a box clamping device is provided. The output end of the external moving device is connected to the support base 1, thereby driving the box clamping device to move. When clamping the box 7, the box clamping device moves closer to the box 7. At this time, the distance between the clamping members of the two clamping mechanisms arranged opposite each other is greater than the width of the box 7. Then, the suction end of the suction member 35 abuts against the box 7 and suctions the box 7. Further, the box clamping device drives the box 7 to move upward a certain distance. Finally, the clamping mechanisms move in a direction that approaches each other until the first clamping plate 261 of the clamping member abuts against the bottom of the box 7. At this time, the box 7 is fixed and can be moved to other positions by the external moving device. With the adsorption end of the adsorption member 35 located within the clamping space, the position of the adsorption end of the adsorption member 35 is higher than the position of the clamping side of the first clamping plate 261. After the adsorption member 35 adsorbs the box body 7, it drives the box body 7 to rise, so that the bottom of the box body 7 forms a space in which the first clamping plate 261 can extend. The clamping side of the first clamping plate 261 can abut against the bottom of the box body 7. At this time, the first clamping plate 261 can provide support for the box body 7, thereby preventing the box body 7 from falling off. This allows the clamping member to stably clamp the box body 7 even with large differences in processing dimensions.

[0026] Reference Figure 1 As shown, the support base 1 is used to connect the clamping assembly 2. The support base 1 is vertically connected to the support plate 11, and the support plate 11 is used to connect the adsorption assembly 3. A connecting flange 12 is connected to the top center of the support base 1, and the connecting flange 12 is used to connect to the output end of the external moving device.

[0027] Reference Figure 2 and Figure 3As shown, the clamping assembly 2 includes a drive member 24 and at least two clamping mechanisms arranged opposite each other. The drive member 24 can be considered as a motor. In this embodiment, there are two clamping mechanisms arranged opposite each other. The number of clamping mechanisms can be set according to the size of the housing 7. The two clamping mechanisms arranged opposite each other form a clamping space for clamping the housing 7. The clamping mechanisms are slidably connected to the support base 1. The drive member 24 can drive the clamping mechanisms to move. Specifically, the clamping mechanism also includes a movable plate 22 and a connecting frame 26. A slide rail 21 is connected to the top of the support base 1 along the length direction. A stop block 211 is also connected to the support base 1. The stop block 211 is located at both ends of the slide rail 21. Each clamping mechanism corresponds to a slide rail 21. A slider 221 is connected to the middle position of the bottom of the movable plate 22. The slider 221 is slidably connected to the slide rail 21, so that the movable plate 22 is slidably connected to the support base 1. The slider 221 can abut against the stop block 211, thereby limiting the extreme movement position of the movable plate 22. The connecting frame 26 is connected to the movable plate 22, which is U-shaped. The bottom ends of the movable plate 22 are connected to the connecting frame 26, and the clamping parts are connected to the bottom side wall of the connecting frame 26.

[0028] The clamping mechanism includes a first clamping plate 261 and a second clamping plate 262. The first clamping plate 261 is horizontally arranged, and the second clamping plate 262 is vertically arranged, so that the plane of the first clamping plate 261 is perpendicular to the plane of the second clamping plate 262. The planes of the first clamping plates 261 of the opposing clamping mechanisms are coplanar, and the planes of the second clamping plates 262 of the opposing clamping mechanisms are parallel. The top side of the first clamping plate 261 is used to abut against the bottom of the housing 7, and the side wall of the second clamping plate 262 is used to abut against the side wall of the housing 7. Both the first clamping plate 261 and the second clamping plate 262 are made of elastic material to avoid damage to the first clamping plate 261, the second clamping plate 262, and the housing 7. The first clamping plate 261, the second clamping plate 262, and the connecting frame 26 of the two clamping mechanisms constitute the clamping space. During the clamping process of the two clamping mechanisms, the bottom of the box 7 is supported by the first clamping plate 261 and the side wall of the box 7 is clamped by the second clamping plate 262, so that the box 7 can be limited in both the vertical and horizontal directions, thereby keeping the box 7 as a whole stable.

[0029] The clamping assembly 2 also includes a transmission component 23 and a synchronous wheel 251. At least two synchronous wheels 251 are rotatably connected to the support base 1. The transmission component 23 is sleeved on the synchronous wheel 251. The output end of the drive component 24 is connected to one of the synchronous wheels 251. Specifically, the transmission component 23 can be considered as a synchronous belt. The clamping assembly 2 also includes a first connecting seat 25, a second connecting seat 253, and a support frame 252. The support frame 252 has a first adjustment hole, which is an oblong hole. The support frame 252 is connected to the support base 1 through the first adjustment hole. The first adjustment hole and the support base 1 can be connected by bolts, thereby allowing the position of the support frame 252 to be adjusted. The first connecting seat 25 is connected to the top of the support frame 252. The synchronous pulley 251 is rotatably connected to the first connecting seat 25. The second connecting seat 253 is connected to the support base 1. A first fastener is connected between the second connecting seat 253 and the support frame 252. The first fastener can be considered as a long bolt with a nut threaded onto it. The first fastener is threaded onto the support frame 252, and the nut abuts against the support frame 252, thereby fixing the position of the support frame 252. Through the arrangement of the support frame 252 and the second connecting seat 253, the position of the first connecting seat 25 can be adjusted, thereby allowing the tension of the transmission component 23 to be adjusted. The drive component 24 is connected to the support base 1, and the output end of the drive component 24 is connected to one of the synchronous pulleys 251, so that the drive component 24 can drive the synchronous pulley 251 to rotate, thereby driving the transmission component 23 to rotate.

[0030] The movable plate 22 is connected to the transmission component 23. Specifically, a fifth connecting seat 27 is connected to the top of the movable plate 22, and a pressure block 271 is connected to the fifth connecting seat 27. The transmission component 23 passes through the space between the fifth connecting seat 27 and the pressure block 271. After the pressure block 271 is connected to the fifth connecting seat 27, the transmission component 23 is clamped between the pressure block 271 and the fifth connecting seat 27. Thus, the rotation of the transmission component 23 can drive the movable plate 22 to move. In the two clamping mechanisms, the movable plate 22 of one clamping mechanism is connected to the transmission position of the transmission component 23 near the support seat 1, and the movable plate 22 of the other clamping mechanism is connected to the transmission position of the transmission component 23 away from the support seat 1. Thus, the rotation of the transmission component 23 can drive the two clamping mechanisms to move towards or away from each other. That is, the driving component 24 can drive the two clamping mechanisms to complete the clamping or releasing action, realizing stepless clamping of the box 7 and improving the clamping range of the clamping assembly 2. (Refer to...) Figure 5 As shown, the clamping assembly 2 also includes a housing 28, which is connected to the first connecting seat 25. The housing 28 has a receiving space, within which the transmission component 23 and the synchronous pulley 251 are located. The bottom of the housing 28 is open, allowing the fifth connecting seat 27 to extend into the receiving space, thereby clamping the transmission component 23 via a pressure plate. The housing 28 prevents external debris and dust from affecting the transmission of the transmission component 23.

[0031] The clamping device for the housing also includes a first detection element 6, which can be regarded as a distance sensor. The first detection element 6 is connected to the controller and is connected to the support plate 11 through the third connecting seat 61. The third support seat 1 is connected to two first detection elements 6 arranged opposite to each other. The detection end of the first detection element 6 faces the transmission component 23. The two first detection elements 6 can detect whether the conveying positions on both sides of the transmission component 23 are broken.

[0032] Reference Figure 1 and Figure 4 As shown, the adsorption assembly 3 includes an adsorption element 35, which is connected to a vacuum source and a support plate 11. Specifically, the adsorption assembly 3 also includes a mounting plate 31 and a connecting plate 33. The mounting plate 31 is connected to the side wall of the support plate 11, and the adsorption element 35 is connected to the connecting plate 33. The mounting plate 31 has multiple connecting holes 32, and the connecting plate 33 has a second adjustment hole 34, which is an oblong hole. The second adjustment hole 34 and the connecting hole 32 are connected by a second fastener, which can be considered a bolt. This allows the connection position between the connecting plate 33 and the mounting plate 31 to be adjusted, thereby enabling the adsorption element 35 to adsorb boxes 7 of different sizes. The adsorption assembly 3 includes multiple adsorption elements 35, making the adsorption of the box 7 by the adsorption assembly 3 more stable. The adsorption end of the adsorption member 35 is located in the clamping space, so that the position of the adsorption end of the adsorption member 35 is higher than the position of the clamping side of the first clamping plate 261. Then, after the adsorption member 35 adsorbs the box 7, it drives the box 7 to rise, so that the bottom of the box 7 forms a space in which the first clamping plate 261 can extend, and the clamping side of the first clamping plate 261 can abut against the bottom of the box 7.

[0033] The clamping device for the box also includes a limiting member 13, which is connected to one end of the support plate 11. The limiting member 13 is columnar, and the limiting end of the limiting member 13 is located within the clamping space. The height of the limiting end of the limiting member 13 is higher than the height of the adsorption end of the adsorption member 35. The limiting member 13 is used to limit the extreme position of the clamping device for the box during the descent process, thereby avoiding damage to the adsorption member 35 due to excessive descent distance.

[0034] The clamping device for the box also includes a second detection element 4 connected to the controller. The second detection element 4 can be regarded as a distance sensor. The second detection element 4 is connected to the support plate 11 through the fourth connecting seat 41. The detection end of the second detection element 4 faces the clamping space. The second detection element 4 is used to detect the distance between the second detection element 4 and the box 7, thereby assisting the adsorption element 35 in adsorbing the box 7.

[0035] The clamping device for the box also includes a vision detection element 5 connected to the controller. The vision detection element 5 is connected to the end of the support plate 11 away from the limiting element 13 via the sixth connecting seat 51. The vision detection element 5 is used to position the box 7, thereby assisting the movement of the clamping device for the box.

[0036] Reference Figure 5 As shown, in use, the clamping device moves vertically towards the box 7 until the suction end of the suction member 35 abuts against and suctions the box 7. Then, the clamping device moves the box 7 upward a certain distance. Finally, the clamping mechanism moves towards each other until the top side of the first clamping plate 261 abuts against the bottom of the box 7, and the side wall of the second clamping plate 262 abuts against the side wall of the box 7. At this point, the box 7 is fixed and can be moved to other positions by an external moving device. For boxes 7 of different widths, both clamping mechanisms can abut against the side wall and bottom of the box 7. For boxes 7 of different heights, after the suction member 35 suctions the box 7 and moves it upward, the clamping mechanism moves towards each other until the first clamping plate 261 is below the box 7. Then, the suction member 35 stops suctioning the box 7, allowing the box 7 to descend onto the first clamping plate 261. Finally, the clamping mechanism completes the clamping of the box 7, thus fixing the box 7.

[0037] This utility model discloses a clamping device for a box. The adsorption end of the adsorption member 35 is located within the clamping space, thus placing the adsorption end of the adsorption member 35 higher than the clamping side of the first clamping plate 261. After the adsorption member 35 adsorbs the box 7, it causes the box 7 to rise, creating a space at the bottom of the box 7 into which the first clamping plate 261 can extend. The clamping side of the first clamping plate 261 abuts against the bottom of the box 7, providing support and preventing the box 7 from falling off. This allows the clamping device to stably clamp boxes 7 with large differences in processing dimensions. The arrangement of the first clamping plate 261 and the second clamping plate 262 limits the position of the box 7 in both the vertical and horizontal directions, thus maintaining the overall stability of the box 7.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
