Technical Field

[0001] The utility model belongs to the technical field of clamping equipment, and in particular relates to a cam type transmission clamp. Background Art

[0002] In the production of secondary batteries, the battery cores are mostly produced by winding machines, and then clamped and transported by clamping equipment.

[0003] In the prior art, most of the equipment for clamping and transporting the core uses cylinder transmission to control the opening and closing of the jaws. Since the jaws need to carry the core back and forth thousands of times, and the repeated movement of the cylinder during the transportation process often causes cylinder gas leakage, cylinder jamming, cylinder air joint leakage, and cylinder sensor alarm. This leads to low production efficiency and affects production capacity. In addition, each time the equipment is changed, the width and height of the jaws need to be manually adjusted, which is also very time-consuming. Utility Model Content

For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0031] Embodiment 1:

[0032] This embodiment provides a cam-type transmission clamp, comprising:

[0033] Base 1;

[0034] A clamping mechanism, wherein the clamping mechanism comprises two groups of clamping assemblies, each group of the clamping assemblies is arranged below the base 1 so as to be movable and adjustable in the Y direction, and each group of the clamping assemblies comprises two cam rockers 2 and two clamping jaws 3 which can synchronously move towards each other in the X direction;

[0035] A transmission mechanism, the transmission mechanism is installed and penetrated on the base 1, and the transmission mechanism includes a screw rod 4, a screw rod nut 5 sleeved on the screw rod 4, and a driving motor 6 for driving the screw rod 4 to rotate;

[0036] Among them, the clamping mechanism also includes a shaft rod 7, the middle part of the shaft rod 7 is connected to the screw nut 5, one end of the two cam rockers 2 in the same group of the clamping assembly is respectively hinged to the two clamping jaws 3, and the other ends of the two cam rockers 2 are jointly hinged to one end of the shaft rod 7; the transmission mechanism is used to drive the shaft rod 7 to rise and fall along the Z direction, and the shaft rod 7 drives the clamping jaws 3 to realize X-direction movement through the cam rocker 2.

[0037] In the present technical solution, one end of the cam rocker 2 is hinged on the shaft 7, and a connecting groove 8 is provided on the other end. The cam rocker 2 and the clamping jaw 3 are hinged by installing a connecting shaft through the connecting groove 8 and the upper end of the clamping jaw 3, and then installing bearings 9 at both ends of the connecting shaft for limiting. It is worth mentioning that the bearing 9 at one end of the connecting shaft is located in the connecting groove 8, and the size of the connecting groove 8 is larger than the outer diameter of the bearing 9, so that when the cam rocker 2 drives the clamping jaw 3 to move in the X direction, the clamping jaw 3 and the cam rocker 2 are not easily stuck.

[0038] After the winding core reaches the specified position, the driving motor 6 runs forward to control the screw rod 4 to rotate forward, so that the screw nut 5 moves downward along the screw rod 4, and the shaft rod 7 moves downward as a whole. The two cam rocker bars 2 hinged on the shaft rod 7 in the same group of clamping jaws rotate with the hinge as the fixed point, so that the other ends of the two cam rocker bars 2 swing, thereby driving the two clamping jaws 3 to move relatively away in the X direction, thereby opening the clamping jaw assembly; then when the entire equipment descends to the specified position, the driving motor 6 runs reversely to control the screw rod 4 to rotate reversely, so that the screw nut 5 moves upward along the screw rod 4, and the shaft rod 7 moves upward as a whole. The two cam rocker bars 2 swing, driving the clamping jaws 3 to move relatively close in the X direction, thereby closing the clamping jaw assembly to clamp the winding core. After clamping the winding core, the entire equipment is conveyed to the unloading position, and the above actions are repeated to complete the unloading.

[0039] In summary, the driving motor 6 is used to control the rotation of the screw rod 4 to drive the shaft rod 7 to move up and down to realize the opening and closing of the clamping jaw assembly, so as to complete the core clamping and handling operation; using this structural design to replace the common cylinder transmission method can effectively reduce the failure rate in the process of core clamping and handling. When the device is changed to change the height and width of the core produced by the winding machine, the opening and closing size of the clamping jaw assembly can be adjusted to adapt to the change in the width of the core by adjusting the parameters of the driving motor 6, and the height change of the core can be adapted by adjusting the Y-direction distance between the two sets of clamping jaw assemblies, thereby saving the change time.
