The production process of the battery generally comprises the steps of proportioning, anode and cathode coating, rolling, slitting, winding/lamination, hot pressing, shell filling and the like. The positive pole piece, the negative pole piece and the diaphragm are assembled and manufactured in a winding or lamination mode to form the basic battery. And then taking out the battery clamp on the battery placing plate through the clamping jaw of the battery hot pressing and discharging device, and transferring the battery clamp into hot pressing equipment for hot pressing and shaping (hot pressing and feeding process). The hot press shaping process of the battery comprises the following steps: the coiled or laminated battery is placed on the hot pressing plate, and the upper and lower hot pressing plates form the battery under the action of certain pressure and temperature, so that the thickness of the battery is kept consistent, the elasticity of the battery is reduced, and the qualification rate of the core assembly is improved. The battery after the completion of the hot pressing is then again taken out from the hot pressing plate to be transferred to the next processing apparatus (hot pressing discharging process).

At present, in the process of clamping a battery from a placing plate or a placing surface of a hot pressing plate, a clamping jaw needs to be clung to the placing surface to be inserted into the bottom of the battery, the clamping jaw is usually directly lowered to be in contact with the placing surface, and hard contact between the clamping jaw and the placing surface enables the clamping jaw to be in an overpressure state, so that the clamping jaw is deformed, the battery is difficult to clamp and is easy to damage.

Referring to fig. 1, an embodiment of the present application provides a battery hot-pressing and blanking device 100 for solving the above-mentioned problems, which includes a supporting frame 1, a clamping mechanism 2 and a pressing mechanism 3. Referring to fig. 6, the clamping mechanism 2 is slidably connected to the support frame 1 along the Z direction, and referring to fig. 6, the clamping mechanism 2 includes a first Y-direction servo module 21 and a clamping jaw assembly 22 that are connected, the first Y-direction servo module 21 is connected to the support frame 1, the clamping jaw assembly 22 includes two opposite clamping jaws 22, and referring to fig. 7, the clamping jaw assembly 22 includes an elastic member 221 and a clamping jaw 222 that are connected. Referring to fig. 4 and 6, the pressing mechanism 3 includes a first Z-direction servo module 31 and a pressing rod assembly 32 connected to each other, and the first Z-direction servo module 31 is connected to the support frame 1. When the clamping mechanism 2 slides along the Z direction to contact with the placement surface of the battery, the clamping jaw 222 is driven by the first Y-direction servo module 21 to perform a clamping action along the Y direction so as to cut into between the bottom surface of the battery and the placement surface and to hold the battery, and the elastic member 221 is used for buffering when the clamping jaw 222 contacts the placement surface. Next, the pressing bar assembly 32 is driven by the first Z-direction servo module 31 to move along the Z-direction to press the battery on the clamping jaw 222. In the process from the start of the contact of the clamping jaw 222 of the battery hot pressing and discharging device 100 to the gradual compression of the placing surface, the pressure between the clamping jaw 222 and the placing surface is continuously increased, the elastic piece 221 is elastically deformed by the pressure, so that the collision energy between the clamping jaw 222 and the placing surface can be absorbed, the impact force and vibration are reduced, and the collision between the clamping jaw 222 and the battery placing surface is buffered, so that the deformation damage of the clamping jaw 222 can be reduced, and the battery is protected.

The battery hot pressing and discharging device 100 in the embodiment of the application can be used for clamping and taking out a battery to and from hot pressing equipment. In other words, the feeding process is included: and clamping and transferring the wound/laminated battery core from the placing plate to a hot pressing plate of the hot pressing equipment. The method comprises the following steps: and taking out the battery core after the hot pressing from the hot pressing plate, and transferring the battery core to the next processing equipment.

The elastic piece 221 in the embodiment of the application can play a role in buffering both in the feeding process and the discharging process. Specifically, during the feeding process, the clamping jaw 222 approaches the placing surface of the placing plate, and the elastic piece 221 buffers the contact between the clamping jaw 222 and the placing plate, so that the clamping jaw 222 gradually presses the placing plate and cuts into the bottom of the battery, and the battery is clamped from the placing plate and is transferred to the hot pressing device by matching with the pressing mechanism 3. The jaws 222 then carry the battery against the rest surface of the hot platen, and the elastic member 221 buffers the contact between the jaws 222 and the hot platen so that the jaws 222 gradually compress the hot platen to rest the battery on the hot platen. During the blanking process, the clamping jaw 222 is close to the hot pressing plate, the elastic piece 221 again buffers the contact between the clamping jaw 222 and the hot pressing plate, so that the clamping jaw 222 gradually presses the hot pressing plate and cuts into the bottom of the battery after the hot pressing is finished, the battery is clamped from the hot pressing plate, and the battery is transferred to the next processing equipment by matching with the pressing mechanism 3 again.

It should be noted that, in the blanking process, compared with the feeding process, a larger compression force is provided between the bottom surface of the battery after the hot pressing and the hot pressing plate, the battery can be clamped only by the clamping jaw 222 cutting into the bottom surface of the battery and then compressing, the clamping jaw 222 needs to apply a larger compression force to the hot pressing plate to cut into the bottom surface of the battery, in the process, the elastic piece 221 can fully buffer collision impact, deformation of the clamping jaw 222 is reduced, and damage caused by clamping the battery in the blanking process is reduced.

The first Z-direction driving mechanism 311 is connected to the third face 123a of the second Z-direction moving mechanism 123. Alternatively, the first Z-drive mechanism 311 may be a cylinder or a motor. The output end of the first Z-direction driving mechanism 311 is connected to one end of the second connecting plate 34, and the other end of the second connecting plate 34 is connected to the first Z-direction moving mechanism 313.

The pressing mechanism 3 further includes a connecting seat 33, the connecting seat 33 is connected to the fourth face 123b of the second Z-direction movement mechanism 123, and the connecting seat 33 is located in the avoidance space 2111.

In some embodiments, the first Z-direction movement mechanism 313 is located in the avoidance space 2111 of the two first Y-direction movement mechanisms 213 and is slidably connected to the first Z-guide rail 312 to move up and down between the two first Y-direction movement mechanisms 213.

Alternatively, the first Z-direction movement mechanism 313 may be a slide plate, a slide block, a slide column, or the like. In some embodiments, the first Z-motion mechanism 313 is a sliding plate, and the plate shape can expand the area of the first Z-motion mechanism 313 to provide enough space to mount the plunger assembly 32. Illustratively, the first Z-motion mechanism 313311 may be provided with four sets of ram assemblies 32, each set of ram assemblies 32 corresponding to a set of jaw assemblies 22, to complete the gripping action on one battery.

It should be noted that the present pressing mechanism 3 is generally used to control the multiple sets of pressing rod assemblies 32. Typically, a Z-servo module is provided for each set of strut assemblies 32, in other words, each set of strut assemblies 32 is provided with a Z-drive mechanism, a Z-guide rail, and a Z-motion mechanism. Thus, the number of the mechanisms is increased, and the whole device is complex in structure, large in number of parts and high in cost. The embodiment of the application can realize the control of four or more groups of compression bar assemblies 32 by only one first Z-direction driving mechanism 311, one first Z-direction guide rail 312 and one first Z-direction movement mechanism 313, thereby further reducing the number of mechanism settings, simplifying the device and further reducing the cost.

The long side of each strut 321 is adjacent to the jaw 222.

Currently, when the pressing rod 321 and the clamping jaw 222 are matched to clamp the battery, the clamping jaw 222 clamps the bottom surface and two opposite side surfaces of the battery, and the pressing rod 321 is pressed in the middle of the battery. Because the clamping jaws 222 are hollow, the battery is pressed by the pressing rod 321, and the middle part of the battery is forced to bend downwards after being pressed down, so that serious deformation is generated. Referring to fig. 8, in order to solve the problem, the present application sets the pressing rod 321 above the clamping jaw 222, so that the projection of the pressing rod 321 on the second portion 2222 of the clamping jaw 222 at least partially coincides with the upper surface of the supporting portion 2222 a. When the pressing rod 321 presses the battery, the first portion 2221 of the clamping jaw 222 abuts against the side surface of the battery, and the supporting portion 2222a of the second portion 2222 of the clamping jaw 222 abuts against the bottom surface of the battery. The pressing rod 321 is pressed on the top surface corresponding to the position of the supporting part 2222a, so that the action points of the pressing rod 321 and the supporting part 2222a on the battery can be at least partially converged to the same position, the clamping force on the battery can be improved, and meanwhile, the battery is prevented from being deformed because the action points of the pressing rod 321 and the clamping jaw 222 are not positioned at the same position.

Referring to fig. 1, in some embodiments, the battery hot-pressing and blanking device 100 further includes an X-direction servo module 4, and the support frame 1 is driven by the X-direction servo module 4 to move along the X-direction.

The third aspect can avoid the pressing mechanism 3 from deforming the battery under pressure during the pressing mechanism 3.

The following describes the operation of the battery hot-pressing and blanking device 100 according to the embodiment of the present application.

Firstly, the feeding process of the hot pressing equipment comprises the following steps:

The first step is to clamp the completed wound/laminated battery from the placement plate: the X-direction servo module 4 drives the frame 11 to move along the X-direction, so that the clamping mechanism 2 and the pressing rod 321 mechanism extend into the vicinity of the placing plate for placing the battery. The second Z-direction driving mechanism 121 drives the second Z-direction moving mechanism 123 to descend through the first connecting plate 13, so that the bottom surface of the clamping jaw 222 of the clamping mechanism 2 presses the placing surface under the buffer of the elastic piece 221 and cuts into the bottom surface of the battery. The first Y-direction driving mechanism 211 drives the two first Y-direction moving mechanisms 213 toward each other to enclose the battery. The first Z-direction driving mechanism 311 drives the second Z-direction movement mechanism 123 to descend through the second connecting plate, so that the pressing rod 321 is matched with the clamping jaw 222 to press the battery. The second Z-direction driving mechanism 121 drives the second Z-direction moving mechanism 123 to rise again to lift the battery from the placement surface. The X-direction servo module 4 drives the framework 11 to retract along the X direction, and the second Y-direction servo module drives the framework 11 to move to the hot pressing equipment along the Y direction.

And a second step of placing the battery on a hot pressing plate of a hot pressing device: the X-direction servo module 4 drives the framework 11 to move along the X direction again, so that the clamping mechanism 2 and the pressing rod 321 mechanism press the battery to extend between the hot pressing plates. The second Z-direction driving mechanism 121 drives the second Z-direction moving mechanism 123 to descend through the first connecting plate 13, so that the bottom surface of the clamping jaw 222 of the clamping mechanism 2 presses the placing surface of the hot pressing plate under the buffering of the elastic piece 221. The first Z-direction driving mechanism 311 drives the plunger assembly 32 to rise, and the plunger 321 releases the battery. The first Y-drive mechanism 211 drives the jaw assemblies 22 away from each other, placing the battery on the hot platen. The second Z-direction driving mechanism 121 drives the second Z-direction moving mechanism 123 to ascend, and the X-direction servo module 4 drives the skeleton 11 to retract along the X-direction, waiting for the battery to finish hot pressing.

Then the blanking process of the hot pressing equipment is as follows:

The first step is to remove the hot pressed battery from the hot platen: the X-direction servo module 4 drives the framework 11 to move along the X direction so as to extend into the hot pressing plate. The second Z-direction driving mechanism 121 drives the second Z-direction moving mechanism 123 to descend so that the bottom surface of the clamping jaw 222 of the clamping mechanism 2 presses against the placement surface of the hot press plate and cuts into the bottom surface of the battery under the buffer of the elastic member 221. The first Y-direction driving mechanism 211 drives the two first Y-direction moving mechanisms 213 toward each other to enclose the battery. The first Z-direction driving mechanism 311 drives the second Z-direction movement mechanism 123 to descend through the second connecting plate, so that the pressing rod 321 is matched with the clamping jaw 222 to press the battery. The second Z-direction driving mechanism 121 in turn drives the second Z-direction moving mechanism 123 upward to lift the battery from the hot platen. The X-direction servo module 4 drives the framework 11 to retract along the X direction, so that the clamping mechanism 2 and the pressing mechanism 3 withdraw from the hot pressing plate. The second Y-direction servo module drives the skeleton 11 to move to the next processing apparatus along the Y-direction.

And secondly, clamping the battery after the hot pressing to the next processing equipment: the X-direction servo module 4 drives the framework 11 to move along the X direction again, so that the clamping mechanism 2 and the compression bar 321 mechanism compress the battery after the hot pressing is completed, and the battery extends into the processing equipment. The second Z-direction driving mechanism 121 drives the second Z-direction moving mechanism 123 to descend through the first connecting plate 13, so that the bottom surface of the clamping jaw 222 of the clamping mechanism 2 presses the placing surface of the processing equipment under the buffer of the elastic piece 221. The first Z-direction driving mechanism 311 drives the plunger assembly 32 to rise, and the plunger 321 releases the battery. The first Y-drive mechanism 211 drives the jaw assemblies 22 away from each other, placing the battery on the processing equipment. The second Z-direction driving mechanism 121 drives the second Z-direction moving mechanism 123 to ascend, and the X-direction servo module 4 drives the frame 11 to retract in the X-direction.
