Description

Technical Field

[0001] The present invention relates to the technical field of batteries, and particularly to a clamping device and a conveying device. Background Art

[0002] In the process of battery production and processing, for a core package with a wrapper attached, a holding fixture is required to press and hold the position where the glue is applied to the wrapper on the core package, and then the core package is rotated.

[0003] In the prior art, a multi-spring mechanism is mainly used to realize the return and reset of the holding fixture. The elasticity and extensibility of the spring become an important guarantee for normal operation. It is necessary to rely on the elasticity of the spring to press against the wrapper and fix the core package through the spring during the transportation of the core package. However, the use of the spring has the problem of insufficient stability, which is likely to cause the movement of the core package or the displacement of the wrapper during transportation. At the same time, in order to avoid the fatigue of the spring, the spring needs to be replaced frequently, resulting in a high use cost.

[0004] Therefore, there is an urgent need for a clamping device and a conveying device to solve the above problems. Summary of the Invention

[0005] According to one aspect of the present invention, a clamping device is provided, which can stably press against the wrapper during the transportation of the core package, reliably clamp the core package, ensure the stability of transportation, and effectively reduce the cost of replacing parts.

[0010] A pressing mechanism includes a pressing plate. One end of the pressing plate is rotatably arranged on the support seat, and the other end of the pressing plate can press the component to be pressed on the material.

[0011] Optionally, multiple ones of the clamping jaws include a first clamping jaw and two second clamping jaws. The first clamping jaw is parallel to the fixed abutment and is disposed on the support base at an adjustable interval along a first direction. The two second clamping jaws are respectively disposed on two sides of the first clamping jaw in a second direction, and the second direction is perpendicular to the first direction. The first clamping jaw approaches or moves away from the fixed abutment along the first direction, driving the two second clamping jaws to approach or move away from each other along the second direction. The fixed abutment, the first clamping jaw, and the two second clamping jaws can clamp the peripheral portion of the material.

[0012] Optionally, the clamping mechanism further includes a bottom plate and side plates. The bottom plate is disposed on a side of the support base away from the material. The first clamping jaw is fixedly connected to a side of the bottom plate away from the fixed abutment and can move along the first direction under the drive of the bottom plate.

[0013] The two second clamping jaws are respectively slidably connected to the bottom plate through the two side plates. When the bottom plate moves away from the fixed abutment along the first direction, it can drive the two side plates to move away from each other along the second direction.

[0014] Optionally, first sliding grooves are respectively formed on two sides of the bottom plate in the second direction. In a direction from the first clamping jaw approaching the fixed abutment, the included angle between the extending directions of the two first sliding grooves gradually increases. First rollers capable of sliding along the two first sliding grooves are respectively and correspondingly disposed on the two side plates.

An inclined surface is provided on the top block, and the bottom plate abuts against the inclined surface.

[0019] Optionally, the pressing mechanism further includes a mounting base and a lifting plate. The mounting base is disposed on the support base. The pressing plate is rotatably connected to the mounting base. The lifting plate is disposed on the mounting base with adjustable height and is rotatably connected to one end of the pressing plate away from the material.

The clamping mechanism is disposed on the support base and includes a plurality of clamping jaws. The plurality of clamping jaws are sequentially arranged along the circumferential direction of the material. The clamping jaws can move in a direction close to or away from the material to clamp and fix the material on the fixed abutting member.

The other end of the pressing plate can press the component to be pressed on the material (such as the vest on the core pack). Only by rotating the pressing plate can the pressing or releasing of the component to be pressed be realized. When the pressing plate rotates and opens and the plurality of clamping jaws of the clamping mechanism move away from each other, an operator can load or unload the material. When the pressing plate presses the component to be pressed and the clamping mechanism clamps the material, the material can be transported. Description of the Drawings

[0047] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0048] This embodiment provides a clamping device, as Figure 1 shown, which can clamp the material 100 (such as a battery core package) and press against the component 200 to be pressed on the material 100 (such as the vest on the core package), so as to ensure the stable transportation of the material 100.

[0049] Specifically, referring to Figure 1 、 Figure 4 and Figure 6 , the clamping device includes a support base 1, a clamping mechanism 2 and a pressing mechanism 3. The support base 1 can be used to place the material 100. A fixed abutting member 11 is provided on the support base 1. One side of the material 100 abuts against the fixed abutting member 11. The fixed abutting member 11 can play a role in initially fixing the material 100 to ensure the support stability of the material 100 during transportation. The clamping mechanism 2 and the pressing mechanism 3 are both provided on the support base 1. The clamping mechanism 2 can clamp and fix the material 100 on the fixed abutting member 11, and the pressing mechanism 3 can press the component 200 to be pressed on the material 100.

[0050] That is to say, when the pressing mechanism 3 does not press the workpiece 200 to be pressed and the clamping mechanism 2 does not clamp the material 100, the operator can load or unload the material 100; when the pressing mechanism 3 presses the workpiece 200 to be pressed and the clamping mechanism 2 clamps the material 100, the stable transportation of the material 100 can be carried out.

[0051] It can be understood that the material 100 can be, but is not limited to, a battery core package, and the workpiece 200 to be pressed can be, but is not limited to, a vest on the core package. The workpiece 200 to be pressed is a component that has been covered or installed on the material 100 in the process before the material 100 arrives.

[0052] As Figures 1 - 3 shown, the pressing mechanism 3 includes a pressing plate 31. One end of the pressing plate 31 is rotatably arranged on the support seat 1, and the other end of the pressing plate 31 can press the workpiece 200 to be pressed on the material 100. By simply rotating the pressing plate 31, the pressing or releasing of the workpiece 200 to be pressed can be realized, and the operation is simple, time-saving and labor-saving.

[0053] Specifically, the pressing mechanism 3 further includes a mounting seat 32 and a lifting plate 33. The mounting seat 32 is arranged on the support seat 1, the pressing plate 31 is rotatably connected to the mounting seat 32, and the lifting plate 33 is arranged on the mounting seat 32 with adjustable height and is rotatably connected to the end of the pressing plate 31 away from the material 100. The lifting plate 33 can drive the pressing plate 31 to rotate, so that the side of the pressing plate 31 away from the lifting plate 33 presses or releases the workpiece 200 to be pressed on the material 100. A lever structure is formed between the lifting plate 33 and the pressing plate 31. By only controlling the lifting of the lifting plate 33, the pressing plate 31 can be driven to rotate, thereby realizing the pressing of the workpiece 200 to be pressed.

[0054] More specifically, the pressing mechanism 3 further includes a mating shaft 36, and the lifting plate 33 is rotatably connected to the pressing plate 31 through the mating shaft 36. Specifically, a first through hole is formed through the lifting plate 33, a second through hole is formed through the end of the pressing plate 31 away from the material 100, and the mating shaft 36 sequentially passes through the first through hole and the second through hole, thereby realizing the rotational connection between the lifting plate 33 and the pressing plate 31.

[0055] Even more specifically, the pressing mechanism 3 further includes a connecting shaft 35, and the pressing plate 31 is rotatably connected to the mounting seat 32 through the connecting shaft 35. In this embodiment, a third through hole is formed through the pressing plate 31, the connecting shaft 35 passes through the third through hole, and both ends of the connecting shaft 35 protrude from both sides of the pressing plate 31 and are respectively rotatably connected to the mounting seat 32.

[0056] Further, as Figure 3As shown, the connecting shaft 35 is arranged in parallel with the mating shaft 36, and the connecting shaft 35 is located on the side of the mating shaft 36 away from the lifting plate 33. That is to say, the connecting shaft 35 is located in the middle of the pressing plate 31. One side of the pressing plate 31 on the connecting shaft 35 is used to press the workpiece 200 to be pressed, and the other side of the pressing plate 31 on the connecting shaft 35 is connected to the lifting plate 33 and can rotate around the axis of the connecting shaft 35 under the drive of the lifting plate 33.

[0057] Continuing, referring to Figure 2 , two parallel mounting plates 321 are provided on the mounting seat 32. Opposite sliding holes 322 are respectively formed on the two mounting plates 321. The length direction of the sliding holes 322 forms an angle with the moving direction of the lifting plate 33. The two ends of the connecting shaft 35 are respectively rotatably connected to the two sliding holes 322 and can slide along the length direction of the sliding holes 322 respectively. With such a setting, when the lifting plate 33 moves downward, the lifting plate 33 drives the end of the pressing plate 31 away from the material 100 to rotate downward. At the same time, the pressing plate 31 can also move away from the material 100 along the sliding hole 322, so that the other end of the pressing plate 31 can move away from the material 100 while rotating and opening, which is convenient for the operator to better place the material 100 on the support seat 1 and effectively avoid collision between the pressing plate 31 and the material 100. In this embodiment, the length direction of the sliding hole 322 is perpendicular to the moving direction of the lifting plate 33.

[0058] Optionally, the pressing mechanism 3 further includes rolling bearings 351. Two rolling bearings 351 are provided. The two rolling bearings 351 are respectively arranged at the two ends of the connecting shaft 35 and are respectively rotatably arranged in the corresponding sliding holes 322. The setting of the rolling bearings 351 can ensure the smoothness of the movement of the connecting shaft 35 along the sliding holes 322, effectively reduce the friction force, and reduce energy losses such as heat generation.

[0059] Continuing to refer to Figure 1 , the pressing mechanism 3 further includes a second driving member 38. The fixed end of the second driving member 38 is arranged on the support seat 1, and the output end of the second driving member 38 is connected to the lifting plate 33. The output end of the second driving member 38 can drive the lifting plate 33 to move up and down, and then drive the pressing plate 31 to rotate. Exemplarily, the second driving member 38 can be selected as a cylinder, a hydraulic cylinder or an electric push rod, etc.

[0060] Specifically, the pressing mechanism 3 further includes a movable pressing plate 39. The movable pressing plate 39 is connected to the output end of the second driving member 38 and can move up and down under the drive of the output end of the second driving member 38. In this embodiment, a pressed portion 331 protrudes from the side of the lifting plate 33 close to the second driving member 38. The movable pressing plate 39 abuts against the pressed portion 331 and can drive the pressed portion 331 to move downward.

[0061] Preferably, the pressing mechanism 3 further includes a second reset member 34, which is clamped between the lifting plate 33 and the mounting seat 32 and is used to drive the lifting plate 33 to reset. Exemplarily, the second reset member 34 can be selected as a reset spring. When the lifting plate 33 moves downward driven by the movable pressing plate 39, the lifting plate 33 compresses the reset spring; when the movable pressing plate 39 moves upward driven by the second driving member 38, the lifting plate 33 rises under the action of the elastic force of the reset spring and returns to its original position.

[0062] Optionally, in order to make the movement of the lifting plate 33 more stable and reliable, as Figure 3 shown, the pressing mechanism 3 further includes a guide rod 37 and a linear bearing for guiding the up and down movement of the lifting plate 33.

[0063] Specifically, the guide rod 37 is fixed on the mounting seat 32 and extends in the vertical direction. The linear bearing is sleeved outside the guide rod 37 and can move up and down along the guide rod 37. The lifting plate 33 is connected to the linear bearing, and the linear bearing can improve the smoothness of the up and down movement of the lifting plate 33.

[0064] Preferably, in this embodiment, a protective layer is provided on the side of the pressing plate 31 facing the material 100. The protective layer can be made of rubber, which can not only reduce the friction between the pressing plate 31 and the workpiece to be pressed 200, but also has an anti-slip function to prevent the workpiece to be pressed 200 and the pressing plate 31 from shifting during the transportation of the material 100.

[0065] Continuing to refer to Figure 1 、 Figure 4 、 Figure 6 and Figure 7 , the clamping mechanism 2 includes a plurality of jaws, which are arranged in sequence along the circumferential direction of the material 100. The jaws can move in a direction close to or away from the material 100 to clamp and fix the material 100 on the fixed abutting member 11. That is to say, through the opening and closing movement of the plurality of jaws in the clamping mechanism 2, the material 100 can be clamped and fixed, effectively preventing the material 100 from sliding relatively during transportation and ensuring the stability of the material 100 during transportation. And there is no need to set a plurality of spring jaws, effectively reducing the cost of replacing parts.

[0066] At the same time, with the cooperation of the clamping mechanism 2 and the pressing mechanism 3, when the pressing plate 31 rotates and opens and the jaws of the clamping mechanism 2 are all away from each other, the operator can load or unload the material 100; when the pressing plate 31 presses the workpiece to be pressed 200 and the clamping mechanism 2 clamps the material 100, the transportation of the material 100 can be carried out, and the operation is simple, greatly improving the transportation efficiency of the material 100.

[0067] Specifically, the multiple clamping jaws include a first clamping jaw 21 and two second clamping jaws 22. The first clamping jaw 21 is parallel to the fixed abutment 11 and is disposed on the support base 1 at an adjustable distance along a first direction. The two second clamping jaws 22 are respectively disposed on both sides of the first clamping jaw 21 in a second direction perpendicular to the first direction. In this embodiment, the first direction is parallel to the width direction of the material 100, and the second direction is parallel to the length direction of the material 100. The first clamping jaw 21 approaches or moves away from the fixed abutment 11 along the first direction, driving the two second clamping jaws 22 to approach or move away from each other along the second direction. That is to say, the first clamping jaw 21 is linked with the two second clamping jaws 22 to clamp and fix three sides of the material 100. On this basis, the fixed abutment 11, the first clamping jaw 21, and the two second clamping jaws 22 can clamp four sides of the material 100.

[0068] More specifically, as Figure 6 and Figure 7 shown, the clamping mechanism 2 further includes a bottom plate 23 disposed on the side of the support base 1 away from the material 100. The first clamping jaw 21 is fixedly connected to the side of the bottom plate 23 away from the fixed abutment 11 and can move along the first direction under the drive of the bottom plate 23. In this embodiment, an avoidance channel is formed on the support base 1, and the first clamping jaw 21 is connected to the bottom plate 23 through a vertical plate, and the avoidance channel is used to avoid the vertical plate. When the bottom plate 23 moves along the first direction, the first clamping jaw 21 can be driven to move synchronously through the vertical plate.

[0069] Further, the clamping mechanism 2 further includes a first guiding component 25 disposed between the bottom plate 23 and the support base 1 for guiding the movement of the first clamping jaw 21 along the first direction. The first guiding component 25 includes a first slide rail extending along the first direction and a first slider slidably engaged with the first slide rail. One of the first slide rail and the first slider is disposed on the support base 1, and the other is disposed on the bottom plate 23.

[0070] More specifically, referring to Figure 7 , the clamping mechanism 2 further includes side plates 24, and the two second clamping jaws 22 are respectively slidably connected to the bottom plate 23 through the two side plates 24. In this embodiment, first sliding grooves 231 are respectively formed on both sides of the bottom plate 23 in the second direction. From the direction in which the first clamping jaw 21 approaches the fixed abutment 11, the included angle between the extending directions of the two first sliding grooves 231 gradually increases. First rollers 241 capable of sliding along the two first sliding grooves 231 are respectively disposed on the two side plates 24. When the bottom plate 23 moves away from the fixed abutment 11 along the first direction, the two first rollers 241 respectively slide along the two first sliding grooves 231, thereby driving the two side plates 24 to move and move away from each other along the second direction. Exemplarily, the first roller 241 can be selected as a cam follower.

[0071] Further, the clamping mechanism 2 further includes a second guiding component 26 disposed between the support base 1 and the side plate 24 for guiding the movement of the second jaw 22 in the second direction. The second guiding component 26 includes a second slide rail 261 extending in the second direction and a second slider 262 slidably engaged with the second slide rail 261. One of the second slide rail 261 and the second slider 262 is disposed on the support base 1, and the other is disposed on the side plate 24.

[0072] Preferably, as Figures 5 - 7 shown, the clamping mechanism 2 further includes a first resetting member 27 disposed between the bottom plate 23 and the support base 1 for driving the bottom plate 23 to reset. Exemplarily, the first resetting member 27 may be a reset spring. When the bottom plate 23 drives the first jaw 21 to move away from the material 100 in the first direction, the bottom plate 23 stretches the reset spring; when the bottom plate 23 no longer moves under force, the bottom plate 23 returns to its original position under the elastic force of the reset spring.

[0073] Optionally, as Figure 4 、 Figure 7 and Figure 8 shown, the clamping mechanism 2 further includes a first driving member 28 and a top block 29. The first driving member 28 is capable of driving the top block 29 to move in a third direction perpendicular to the first direction and the second direction. In this embodiment, the third direction is parallel to the vertical direction. The top block 29 is provided with an inclined surface 291, a connecting plate 232 is disposed under the bottom plate 23, and a second roller 233 is disposed on the connecting plate 232. The second roller 233 is in rolling engagement with the inclined surface 291. When the first driving member 28 drives the top block 29 to rise, the second roller 233 rolls along the inclined surface 291, thereby driving the bottom plate 23 to move away from the fixed abutting member 11 in the first direction, and further driving the first jaw 21 away from the material 100. Exemplarily, the first driving member 28 may be a cylinder, an oil cylinder or a motor in the prior art. Similarly, the second roller 233 may be a cam follower.

[0074] The working principle of the clamping device provided in this embodiment is as follows (taking the clamped material 100 as a battery core package as an example):

[0075] 1. Before the material 100 arrives, the second driving member 38 drives the movable pressing plate 39 and the lifting plate 33 to descend. At this time, the second resetting member 34 at the lower part of the lifting plate 33 is compressed, and the pressing plate 31 and the rolling bearing 351 move away from the material 100 along with the mating shaft 36. At the same time, one end of the pressing plate 31 close to the lifting plate 33 is also subjected to a downward force in one direction by the mating shaft 36, thereby driving the pressing plate 31 to rotate, so that the end of the pressing plate 31 away from the lifting plate 33 rotates upward and warps around the connecting shaft 35.

[0076] 2. While the second driving member 38 descends, the first driving member 28 drives the top block 29 to ascend. The top block 29 pushes the second roller 233 to move away from the material 100, thereby pulling the bottom plate 23, the vertical plate, and the first jaw 21 to move. While the second roller 233 drives the bottom plate 23, the vertical plate, and the first jaw 21 to move, the first reset member 27 is stretched. At this time, the first roller 241 moves within the first chute 231 and drives the side plate 24 to move, thereby realizing the opening of the clamping mechanism 2.

[0077] 3. After the material 100 is placed, the second driving member 38 drives the movable pressure plate 39 to ascend. The second reset member 34 rebounds, and the pressure plate 31 moves towards the material 100 along with the rolling bearing 351. The end of the pressure plate 31 away from the lifting plate 33, i.e., the glue application position, descends to press the piece to be pressed 200.

[0078] 4. While the second driving member 38 ascends, the first driving member 28 drives the top block 29 to descend. The first reset member 27 retracts, driving the second roller 233 to reset, and driving the bottom plate 23, the vertical plate, and the first jaw 21 to return to their original positions. The first roller 241 moves back to its original position relatively, and at the same time, the side plate 24 retracts, and the clamping structure stably clamps the material 100.

[0079] 5. After each mechanism completes its action, it returns to the initial state.

[0080] This embodiment also provides a conveying device, which includes a transfer device and the above clamping device. The clamping device is arranged on the transfer device and moves under the drive of the transfer device, thereby conveying the material 100 (such as a battery core package) between various workstations, improving the automation degree and work efficiency of the operation. Exemplarily, the transfer device can be a conveyor belt mechanism or a turntable mechanism, etc., which is not limited here.

[0081] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
