Description

Technical Field

[0001] The utility model belongs to the technical field of pallet clamping devices, and in particular relates to a clamping device and pallet transport equipment. Background Art

[0002] The battery cells in secondary batteries are composed of multiple stacked cores. The cores are loose after winding and need to be finally shaped through hot pressing. Then, it is tested whether the negative electrode in the core wraps the positive electrode to avoid short circuit during subsequent use of the battery cells.

[0029] Embodiment 1:

[0030] This embodiment provides a clamping device, comprising:

[0031] A lifting assembly, the lifting assembly comprising a lifting platform 1 and a first driving member 2, the lifting platform 1 is mounted on a driving end of the first driving member 2, and the first driving member 2 is used to control the lifting platform 1 to move up and down along the Z direction;

[0032] Two groups of clamping assemblies, the clamping assemblies include a clamping member 3 and a second driving member 4, the two second driving members 4 are symmetrically arranged on both sides of the lifting platform 1 along the X direction, the clamping member 3 is installed on the driving end of the second driving member 4, and the second driving member 4 is used to drive the clamping member 3 to move along the X direction and clamp the tray 8 under the lifting platform 1 in the X direction;

[0033] Two groups of clamping assemblies, the two groups of clamping assemblies are respectively installed on the two clamping members 3, the clamping assemblies include a clamping member 5 and a third driving member 6, the third driving member 6 is installed on the clamping member 3, the clamping member 5 is installed on the driving end of the third driving member 6, and the third driving member 6 is used to drive the clamping member 5 to clamp the tray 8 along the Z direction.

[0034] In the present technical solution, when the clamping device performs the clamping operation, the first driving member 2 is first used to control the lifting platform 1 to descend in the Z direction. After the lifting platform 1 descends to a certain height, the two second driving members 4 on the lifting platform 1 respectively control the two clamping members 3 to be relatively close to each other along the X direction, so as to achieve X-direction clamping of the pallet 8. Then the third driving member 6 controls the clamping member 5 to descend along the Z direction, and the clamping member 5 is used to limit the pallet 8 in the Z direction, so as to complete the clamping operation of the pallet 8.

[0035] Through this structural design, two clamping members 3 are used to clamp the pallet 8 to be clamped in the X direction, and two pressing members 5 are used to limit the pallet 8 in the Z direction, thereby enhancing the clamping stability of the pallet 8 by the clamping device, preventing the pallet 8 from shaking during the clamping and transportation process, and thus ensuring that the inside of the roll core on the pallet 8 can maintain the complete structure after hot pressing, which is highly practical.

[0036] Embodiment 2:

[0037] This embodiment provides a clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0038] Furthermore, the clamping member 3 comprises:

[0039] A fixing seat 31, wherein the fixing seat 31 is mounted on a driving end of the second driving member 4;

[0040] The clamping claw 32 is installed on the fixing seat 31 and is used for clamping the X-direction end of the tray 8 .

[0041] In the present technical solution, the fixed seat 31 is installed on the driving end of the second driving member 4 by setting fasteners, and the clamping jaw 32 is installed on the fixed seat 31 by setting fasteners. The second driving member 4 starts to control the fixed seat 31 to move along the X direction, driving the clamping jaw 32 to move along the X direction and clamp the fixed tray 8.

[0042] Furthermore, the clamping jaw 32 includes:

[0043] A clamping portion, which is disposed on the fixing seat 31 and is used to clamp the tray 8 in the X direction;

[0044] The bottom supporting portion is arranged on the clamping portion and is used to support the bottom of the tray 8 in the Z direction.

[0045] In the present technical solution, the clamp 32 includes a clamping portion and a supporting portion. When the clamp 32 clamps the pallet 8 in the X direction, the clamping portion of the clamp 32 clamps the end of the pallet 8 in the X direction, and the supporting portion of the clamp 32 is located at the bottom of the pallet 8, supporting the bottom of the pallet 8 in the Z direction, and then cooperates with the clamping member 5 to apply a Z-direction limit pressure to the pallet 8, so that the pallet 8 is clamped more firmly, effectively improving the stability of the pallet 8 during movement.

[0046] Furthermore, the clamping portion and the bottom supporting portion are an integrated "L"-shaped structure. Through this structural design, the clamping claws 32 can clamp the tray 8 along the X direction and lift it along the Z direction.

[0047] Embodiment 3:

[0048] This embodiment provides a clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0049] Furthermore, the pressing member 5 comprises:

[0050] A connecting portion, the connecting portion being mounted on a driving end of the third driving member 6;

[0051] The pressing portion is arranged on the connecting portion and is used to abut against one side of the tray 8 along the Z direction.

[0052] In the present technical solution, the clamping part and the connecting part are an integrated structure. The connecting part is installed on the driving end of the third driving member 6 by setting a fastener. The third driving member 6 controls the connecting part to move along the Z direction, driving the clamping part to abut against one side of the tray 8 in the Z direction, thereby achieving a Z-direction clamping effect on the tray 8.

[0053] Embodiment 4:

[0054] This embodiment provides a clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0055] Furthermore, it also includes a limiting member 7, which is installed on the bottom of the lifting platform 1 along the Z direction.

[0056] In the present technical solution, when the first driving member 2 controls the lifting platform 1 to descend, when the limiter 7 abuts against the tray 8 in the Z direction, it indicates that the clamping member 3 has descended to a suitable height, and the first driving member 2 stops working. Then the second driving member 4 and the third driving member 6 respectively control the movement of the clamping member 3 and the pressing member 5 to complete the clamping operation of the tray 8. Through this structural design, the distance between the lifting platform 1 and the tray 8 can be more accurately controlled to ensure that the lifting platform 1 stops at an appropriate height, and to prevent the lifting platform 1 from squeezing the winding core and causing damage to the winding core.

[0057] Furthermore, there are multiple limiting members 7 , which are detachably arranged on the periphery of the lifting platform 1 .

[0058] In the present technical solution, the limit member 7 can be integrally connected to the lifting platform 1, or can be detachably installed on the lifting platform 1. Preferably, the limit member 7 and the lifting platform 1 are designed to be detachably connected. When the limit member 7 is damaged, it can be disassembled and replaced, which reduces maintenance costs and extends the service life of the clamping device.

[0059] There are several limit members 7 installed on the lifting platform 1 to enhance the reliability of the limit function. Even if one limit member 7 fails, the remaining limit members 7 can still function to ensure that the lifting platform 1 will not squeeze the roll core on the tray 8.

[0060] Several limiting members 7 can be arranged along the circumference of the lifting platform 1. Through this structural design, the limiting effect is enhanced, and the resistance exerted on the lifting platform 1 can be evenly distributed on the lifting platform 1, thereby avoiding damage to the lifting platform 1 due to uneven force. Preferably, there are four limiting members 7, which are respectively installed on the four corners of the lifting platform 1, thereby ensuring that the lifting platform 1 is evenly stressed, reducing production costs and improving economic benefits.

[0061] Furthermore, the limiter 7 is a buffer. A concave hole 10 adapted to the end of the piston rod of the buffer is provided on the tray 8. When the buffer abuts against the tray 8, the end of the piston rod of the buffer is located in the concave hole 10. Through this structural design, the buffer can buffer the impact force when the clamping device reaches the limit position, making the stop more stable and avoiding the vibration of the tray 8 caused by the impact.

[0062] Embodiment 5:

[0063] This embodiment provides a clamping device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0064] Furthermore, the first driving member 2, the second driving member 4 and the third driving member 6 are all cylinders.

[0065] In the present technical solution, the first driving member 2, the second driving member 4 and the third driving member 6 are all cylinders, which have a fast response speed and can be started and stopped quickly. The cylinder structure is relatively simple and relatively easy to install and maintain, which can reduce the installation and maintenance costs of the equipment. At the same time, the energy consumption is low, which is beneficial to energy saving and environmental protection.

[0066] Embodiment 6:

[0067] This embodiment provides a pallet transport device, including a pallet 8 and a clamping device as described in any one of the above embodiments 1-5, wherein the pallet 8 is provided with limiting grooves 9 that are structurally compatible with the clamping member 3 and the clamping member 5 on both sides along the Z direction.

[0068] In the present technical solution, a plurality of limit grooves 9 are provided on the pallet 8. When the clamping device clamps the pallet 8, the base supporting portion of the clamping jaw 32 and the pressing portion of the pressing member 5 are respectively located in the limit grooves 9, thereby avoiding relative displacement between the clamping jaw 32 and the pallet 8 as well as between the pressing member 5 and the pallet 8, and effectively enhancing the abutment reliability between the clamping jaw 32 and the pallet 8 as well as between the pressing member 5 and the pallet 8, thereby improving the stability of the pallet 8 during clamping and transportation.

[0069] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
