Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it should be understood that the described embodiments are only one sub-embodiments, rather than complete embodiments, in the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, which is a schematic structural diagram of an embodiment of the hot pressing apparatus of the present application, the hot pressing apparatus 100 may include a frame 10, a first mounting plate 20, a first mounting plate 21, a supporting plate 30, a first clamping mechanism 40, a driving mechanism 60, a first heating mechanism 70, and a second clamping mechanism 80.
With reference to fig. 1, the rack 10 is provided with an accommodating groove 11, and the supporting plate 30, the first clamping mechanism 40, the battery cell 50, and the like may be located in the accommodating groove 11. The first mounting plate 20 is slidably connected to the frame 10. For example, the first mounting plate 20 may be connected to the frame 10 by a slider or the like so that the first mounting plate 20 can slide on the frame 10. The second mounting plate 21 is fixed on the frame 10, and the first mounting plate 20 is parallel to the second mounting plate 21.
The support plate 30 is disposed on opposite surfaces of the first mounting plate 20 and the second mounting plate 21, respectively, and the surface of the support plate 30 is provided with a groove 31. Wherein, the grooves 31 on the surface of each supporting plate 30 can be 2 symmetrically arranged. It will be appreciated that the two opposing mounting plates 20 are each provided with a pallet 30, and thus the pallet 30 on the first mounting plate 20 and the pallet 30 on the second mounting plate 21 are opposite, as are the recesses 31 of the two pallets 30.
The first clamping mechanism 40 is disposed on the opposing surfaces of the first mounting plate 20 and the second mounting plate 21, respectively, it being understood that the first mounting plate 20 is disposed with the support plate 30 and the first clamping mechanism 40 facing the same side, and the second mounting plate 21 is disposed with the support plate 30 and the first clamping mechanism 40 facing the first mounting plate 20. Wherein the number of first clamping mechanisms 40 may be twice the number of pallets 30, e.g., as shown in fig. 1, the first clamping mechanisms 40 may be 4 sets, the pallets 30 may be 2 sets, etc. Of course, other numbers of combinations are also possible, as long as the pressurization of the battery cell 50 is satisfied. The first clamping mechanism 40 on the first mounting plate 20 and the first clamping mechanism 40 on the second mounting plate 21 are opposite to each other, and a clamping groove 12 for accommodating the battery cell 50 is formed.
Wherein, the first clamping mechanism 40 further comprises a first driving member 41 and a jacking clamping member 42. One end of the first driving member 41 is connected to the first mounting plate 20, and the other end of the first driving member 41 is connected to the lifting holder 42. Since the first mounting plate 20 and the second mounting plate 21 are both provided with the first clamping mechanism 40 having the same structure, the first clamping mechanism 40 provided on the second mounting plate 21 will be described as an example. One end of the first driving member 41 is connected to the second mounting plate 21, and the other end of the first driving member 41 is connected to the lifting clamp 42. The first driving member 41 is used for driving the jacking clamping member 42 to extend or retract relative to the groove 31. The jacking clamping piece 42 is used for clamping the battery cell 50 when extending out of the groove 31. It will be appreciated that the first clamping mechanism 40 on the first mounting plate 20 is coupled to the first clamping mechanism 40 on the second mounting plate 21 in the same manner. That is, the first mounting plate 20 and the second mounting plate 21 which are arranged oppositely are provided with the jacking clamping pieces 42, so that under the pushing of the first driving piece 41, the two jacking clamping pieces 42 which are opposite move towards each other so as to be used for clamping the battery cell 50. The jacking clamping piece 42 can be matched and embedded with the groove 31 when being retracted relative to the groove 31, so that the jacking clamping piece 42 and the supporting plate 30 form a flat pressing plane, and the shape of the groove 31 is the same as that of the jacking clamping piece 42, so that the flat pressing plane can be formed. That is, when the external force pushes the lifting clamping members 42 on the two oppositely arranged mounting plates, the lifting clamping members 42 further move back and forth while keeping the clamping state of the battery cell 50, so that the lifting clamping members 42 enter the grooves 31 of the supporting plate 30 to form a flat pressing plane. One support plate 30 and two sets of first clamping mechanisms 40 cooperate to form a pressing plane, and two pressing planes can press the battery cell 50.
The driving mechanism 60 is disposed on the frame 10, and the driving mechanism 60 may be fixed on one side of the frame 10. The drive mechanism 60 is used to drive the first mounting plate 20 to move the first mounting plate 20 toward the second mounting plate 21.
The driving mechanism 60 may include a driving main body 61 and an expansion rod 62, the driving main body 61 may be a pressure cylinder, the expansion rod 62 may be a piston rod, and the like, and the driving mechanism 60 may also be an electric cylinder, and the like. The specific type and structure of the driving mechanism 60 is not limited herein as long as it is sufficient to provide a driving force to drive the first mounting plate 20. The driving body 61 drives the telescopic rod 62 to reciprocate, and the telescopic rod 62 penetrates through the rack 10 and abuts against one side of the first mounting plate 20, which is far away from the supporting plate 30. The driving force of the driving mechanism 60 is greater than the driving force of the first clamping mechanism 40, so that the driving mechanism 60 simultaneously compresses the first driving member 41 to make the jacking clamp 42 and the supporting plate 30 form a pressing plane, and further presses the battery cell 50 clamped by the pressing plane.
A first heating mechanism 70 is disposed on the supporting plate 30 and/or the lifting clamp 42, and the first heating mechanism 70 is used for heating the battery cell 50. That is, the first heating mechanism 70 may be fixedly disposed on only the pallet 30, or the first heating mechanism 70 may be fixedly disposed on only the jacking-up clamp 42, or the first heating mechanism 70 may also be fixedly disposed on both the pallet 30 and the jacking-up clamp 42. The number of the first heating mechanisms 70 may be 4, 6, 8, 10, 12, or the like, and is not particularly limited herein, as long as the cells 50 can be heated sufficiently and uniformly.
Through the tight electric core 50 of first clamping mechanism 40 clamp, drive first mounting panel 20 by actuating mechanism 60 again towards the motion of second mounting panel 21, and then make jacking holder 42 and layer board 30 constitute the plane of exerting pressure, pressurize the electric core 50 of centre gripping by the plane of exerting pressure, and heat electric core 50 through first heating mechanism 70, realize the design to electric core 50 pressurization and heating function in an organic whole, the use quantity and the area of equipment have been reduced, and corresponding transport flow has been reduced, manufacturing cost is reduced, in addition, hot press unit 100 can heat and pressurize electric core 50 simultaneously, electric core 50's hot pressing efficiency has effectively been promoted.
Referring to fig. 1 and 2, the first clamping mechanism 40 may further include a transmission pushing block 43, and the transmission pushing block 43 fixedly connects the first driving member 41 and the jacking clamp member 42. That is, the first driving member 41 is fixedly connected to the transmission pushing block 43, the transmission pushing block 43 is further fixedly connected to the jacking clamping member 42, and the first driving member 41 indirectly drives the jacking clamping member 42. The first driving member 41 may be symmetrically disposed with respect to the supporting plate 30, and the first driving member 41 may include an air cylinder and a cylinder rod, wherein the air cylinder drives the cylinder rod to reciprocate, and as the driving principle of the first driving member 41 is known, if the jacking clamping member 42 is directly driven by the air cylinder and the cylinder rod, the first driving member 41 is correspondingly disposed under the jacking clamping member 42. Therefore, the first driving pieces 41 indirectly drive the jacking clamping pieces 42 through the transmission pushing blocks 43, so that the situation that the plurality of first driving pieces 41 are too close to each other can be avoided, and the risk that the first driving pieces 41 are too close to each other to cause mutual influence during driving is reduced. And the first driving member 41 can be spaced apart to make full use of the space of the mounting plate 20, while also facilitating later maintenance and management of the corresponding components.
Optionally, the hot-press apparatus 100 may further include a connecting member 44, and the two driving pushing blocks 43 located on the same side are fixedly connected by the connecting member 44. It can be understood that the transmission pushing blocks 43 driven by the symmetrical first driving members 41 on the first mounting plate 20 are fixedly connected through the connecting member 44, and the transmission pushing blocks 43 driven by the symmetrical first driving members 41 on the second mounting plate 21 are fixedly connected through the connecting member 44. The connecting piece 44 can ensure that the first driving piece 41 on the same mounting plate drives the connecting piece 44 to have the same displacement, so that the expansion and contraction of each jacking clamping piece 42 are synchronous, and the upper and lower expansion and contraction quantities are different. The connecting piece 44 is provided with a recess 441 at the center for avoiding the clamping jaw of the battery cell 50, that is, the two transmission pushing blocks 43 are not close together, but are separated by the recess 441. In addition, the concave part 441 can prevent the clamping jaw of the battery cell 50 from interfering with the transmission pushing block 43, so that the safety of the clamping jaw in the grabbing process is ensured.
The back of the transmission pushing block 43 may be further provided with a guiding element 45, and the guiding element 45 is used for ensuring that the telescopic direction of the transmission pushing block 43 is fixed when the first driving element 41 drives the transmission pushing block 43 to telescope. The guiding elements 45 can be distributed on the opposite corners of the transmission pushing block 43, as shown in fig. 2, two transmission pushing blocks 43 form a rectangular frame, and the guiding elements 45 are distributed on the four corners of the rectangular frame. Through the mode, the shaking probability of the transmission push block 43 during movement can be reduced, and the jacking clamping piece 42 is more stable when stretching.
In some embodiments, referring to fig. 2, the jacking clamp 42 may be a bar shape and includes two spaced jacking clamps 42, and two ends of the two bar shaped jacking clamps 42 are respectively connected to two opposite frame strips of the frame-shaped transmission push block 43. That is, through respectively being provided with two jacking holders 42 in electric core 50's both sides, and two jacking holders 42 evenly distributed are in electric core 50's the position that is close to the center to can make jacking holder 42 fully butt to electric core 50, and then be favorable to the drive power of cylinder to pass to electric core 50, make the centre gripping to electric core 50 more steady.
Optionally, the thermo-compression device 100 may further include a stopper (not shown), which may be fixed on the second mounting plate 21 on a side facing the first mounting plate 20. The stopper is used for resisting the first mounting plate 20 to further move towards the second mounting plate 21 when the first mounting plate 20 moves to a certain extent towards the second mounting plate 21. Therefore, the driving mechanism 60 can be prevented from moving towards the second mounting plate 21 when pressing the first mounting plate 20, and the thickness of the pressing battery cell 50 can be controlled through the limiting block.
Alternatively, the first driving member 41 is a cylinder, and the diameters of the cylinders on the first mounting plate 20 and the second mounting plate 21 are the same or different. It can be understood that, for the air cylinders fixed on the first and second opposite mounting plates 20 and 21, the cylinder diameters of the air cylinders are the same, and the clamping forces of the two opposite jacking clamping pieces 42 are the same, so that the electric core 50 can be clamped. If the cylinder diameters of the cylinders are different, for example, the cylinder diameter of the cylinder close to the driving mechanism 60 is smaller than the cylinder diameter of the cylinder far from the driving mechanism 60, and the driving force generated by the large cylinder diameter is also large, so that when the cell 50 is clamped by the jacking clamping piece 42, the cell 50 has a tendency of being biased to abut against the side close to the driving mechanism 60, and thus, the position of the cell 50 can be fixed when the cell 50 is clamped, and the cell 50 can be positioned.
In some embodiments, referring to fig. 1, the frame 10 may further include a wire-track slider mechanism 13, and the wire-track slider mechanisms 13 are respectively located at two sides of the frame 10. The linear rail slider mechanism 13 includes linear rails (not shown) and sliders (not shown), the linear rails are disposed in parallel on the frame 10, the sliders are slidable transversely on the linear rails, and the first mounting plate 20 is fixedly connected to the sliders so that the first mounting plate 20 is slidable relative to the linear rails. The first mounting plate 10 can be made to slide on the frame 10 without positional deviation in the above manner.
Alternatively, with continued reference to fig. 1, the thermo-compression apparatus 100 may further include a pressure sensor 14, the pressure sensor 14 being disposed between the driving mechanism 60 and the first mounting plate 20, the pressure sensor 14 being configured to detect the driving force generated by the driving mechanism 60. Specifically, the pressure sensor 14 is disposed at a position where the telescopic rod 62 abuts against the mounting plate 20, the pressure sensor 14 is configured to detect a driving force generated by the driving body 61 on the mounting plate 20, and when the driving force reaches a certain preset value, the driving body 61 stops applying pressure continuously. The pressure sensor 14 can detect the pressure generated by the driving mechanism 60 on the mounting plate 20, so as to avoid the damage to the battery cell 50 caused by excessive driving force of the driving mechanism 60 due to pressure transition.
In some embodiments, with continued reference to fig. 1, the thermocompression device 100 may further include a plurality of second clamping mechanisms 80, wherein the second clamping mechanisms 80 are disposed between the first mounting plate 20 and the second mounting plate 21 and are arranged along a direction perpendicular to a line connecting the first mounting plate 20 and the second mounting plate 21. The second clamping mechanism 80 may include a second driving member 81 and a second clamping member 82, the second driving member 81 may be an air cylinder or the like, the second clamping member 82 may be a flat pressing plate, and the second driving member 81 drives the second clamping member 82 to move vertically to press the battery cell 50 vertically. The second clamping member 82 may further have a second heating mechanism (not shown), for example, the second heating mechanism may be embedded in the second clamping member 82. The second heating mechanism is used for heating the battery cell 50. In this way, the cell 50 can be pressurized and heated simultaneously in the vertical direction, so that the cell 50 can be pressurized and heated in all directions, and the structure of the cell 50 which is hot-pressed out is more stable.
Alternatively, the first heating mechanism 70 may include a heating body 71 and a temperature measuring body 72, where the heating body 71 is used to generate heat, and may be a heating rod or the like, and the temperature measuring body 72 is used to detect the temperature of the electrical core 50, and may be a thermocouple or the like, for example. The heating body 71 and the temperature measuring body 72 can be embedded in the supporting plate 30 or the jacking clamping piece 42, and the temperature monitoring of the heating battery core 50 can be realized by the above method, so that the damage to the battery core 50 caused by overhigh heating temperature is prevented. Correspondingly, the second heating mechanism 80 may also be a combination of a heating rod and a thermocouple to achieve heating and monitoring of temperature, and the temperature monitoring of multiple surfaces of the battery cell 50 is favorable for achieving temperature equalization during heating, so as to avoid uneven heating of the battery cell 50.
Referring to fig. 3 and 4, the thermo-compression apparatus 100 may further include at least one third mounting plate 22 and at least one first link 23. The number of the third mounting plates 22 may be 1, 3, or 5, etc., the number of the first links 23 may be 1, 3, or 5, etc., and the number of the third mounting plates 22 and the number of the first links 23 may be set according to practical situations, and is not limited herein. The third mounting plate 22 is located between the first mounting plate 20 and the second mounting plate 21 and is parallel to the first mounting plate 20. The third mounting plate 22 is provided with a support plate 30 and a first clamping mechanism 40 on opposite sides thereof. The third mounting plate 22 is slidably connected to the frame 10, for example, the third mounting plate 22 may be slidably connected to the frame 10 through the wire-rail slider mechanism 13.
When only one third mounting plate 22 is provided, the first link 23 connects the first mounting plate 20 and the third mounting plate 22. Wherein, one end of the first connecting rod 23 is provided with a long waist-shaped hole 231. One end of the first mounting plate 20 is slidably connected in the elongated hole 231 by the first connecting block 24 so that the distance between the first mounting plate 20 and the third mounting plate 22 is adjustable. When only two third mounting plates 22 are provided, the first connecting rod 23 connects the first mounting plate 20 and the third mounting plate 22, and two adjacent third mounting plates 22 are connected through the first connecting rod. Wherein, one end of the first mounting plate 20 is slidably connected in the long-waist-shaped hole 231 through the first connecting block 24, and one end of the third mounting plate 22 is slidably connected in the long-waist-shaped hole 231 through the first connecting block 24.
With continued reference to fig. 4, when more than two third mounting plates 22 are provided, the first link 23 connects the first mounting plate 20 and the third mounting plate 22 that is closest to the first mounting plate 20. The first connecting rods 23 are alternately connected with the third mounting plates 22, and two ends of each third mounting plate 22 are respectively connected with the first connecting rods 23. Wherein, first connecting rod 23 one end is equipped with long waist shape hole 231, and first mounting panel 20 one end passes through first connecting block 24 sliding connection in long waist shape hole 231, and the one end of third mounting panel 22 passes through first connecting block 24 sliding connection in long waist shape hole 231 to make between first mounting panel 20 and the third mounting panel 22, the distance between the adjacent third mounting panel 22 is adjustable, realizes the centre gripping of electricity core 50 or the pressurization function. The driving mechanism 60 directly drives the first mounting plate 20 to move towards the second mounting plate 21, and the third mounting plate 22 is correspondingly moved towards the second mounting plate 21 by the first connecting rod 23. Through the mode, pressurization to electric core 50 can be realized to can make each mounting panel get back to initial position again through the interlock of first connecting rod 23 after accomplishing the pressurization, make hot press unit 100 more nimble, and only need a actuating mechanism 60 can realize the drive of a plurality of mounting panels, promote hot press unit's hot pressing efficiency.
With reference to fig. 3, the frame 10 may be provided with a receiving groove 11 along the transverse direction. The supporting plate 30, the first clamping mechanism 40, the first mounting plate 20, the second mounting plate 21, the third mounting plate 22 and the battery cell 50 are transversely arranged and accommodated in the accommodating groove 11. The mounting plates are spaced apart from each other to divide the accommodating groove 11 into a plurality of small clip grooves 12. It can be understood that the supporting plate 30 on the first mounting plate 20, the first clamping mechanism 40 and the supporting plate 30 and the first clamping mechanism 40 on the third mounting plate 22 form a set of hot pressing units, the supporting plate 30 and the first clamping mechanism 40 on two adjacent third mounting plates 22 form a set of hot pressing units, and the supporting plate 30 on the second mounting plate 21, the first clamping mechanism 40 and the supporting plate 30 and the first clamping mechanism 40 on the third mounting plates 22 form a set of hot pressing units.

Between the thermocompression units formed by adjacent third mounting plates 22, a restriction block may be fixed to one of the third mounting plates 22. Between the thermal pressing unit formed by the second mounting plate 21 and the nearest third mounting plate 22, a restriction block may be fixed to a side of the second mounting plate 21 facing the third mounting plate 22. In this way, the driving mechanism 60 can be prevented from excessively compressing the space of the hot pressing unit formed by each mounting plate, so that the risk that the battery cell 50 is damaged by pressurization is reduced, and the thickness of each pressurized battery cell 50 can be controlled by the limiting block.
By adopting the above mode, at least one group of battery cells 50 can be heated and pressurized at the same time, and the hot-pressing efficiency of the battery cells 50 is further improved.
