[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, a fully automatic battery cell heating and hot pressing device 102, wherein the placing component 211 comprises an inlet and outlet groove 2113 arranged in the placing block 2112, a connecting tube 2114 is rotatably arranged in the inlet and outlet groove 2113, a telescopic tube 2115 is fixedly passed through the connecting tube 2114, a suction plate 2116 is arranged on the telescopic tube 2115, and the suction plate 2116 is connected with the telescopic tube 2115. When the motor 208 rotates, the output end of the motor 208 drives the wheel 209 to rotate synchronously, and at the same time, the wheel 209 rotates and moves, and the wheel 209 drives the fixed seat 207, the rotating shaft 206 and the support The support seat 203 moves synchronously, and the support seat 203 drives the ball 205 on the clamping block 204 to rotate and move along the curved track 201, so that the transfer mechanism 2 as a whole moves along the curved track 201. Similarly, the transfer mechanism 2 on the straight track 202 has the same working principle as the transfer mechanism 2 on the curved track 201. The transfer mechanism 2 on the straight track 202 is used to transfer the battery cell to the heating device 101, heat the battery cell by the heating device 101, and transfer the heated battery cell from the heating device 101 to the transfer mechanism 2 on the curved track 201. Figure 3 As shown, the transfer mechanism 2 on the curved track 201 is used to transfer the heated battery cells to the hot pressing device 102, and the ball 205 is in contact with the straight track 202 and the curved track 201, which can reduce friction, so that the friction force of the transfer mechanism 2 is small when it is displaced; Furthermore, a piston 2117 is slidably provided in the connecting tube 2114, a cylinder 2118 is provided on the placing block 2112, and the output end of the cylinder 2118 is connected to the piston 2117. In the initial state, the gantry loading robot 103 is used to transfer the battery cell to the transfer mechanism 2 on the linear track 202, and the gantry unloading robot 104 is used to unload the hot-pressed battery cell. When in use, the gantry loading robot 103 places the battery cell on the transfer mechanism 2 on the linear track 202, and transfers the battery cell to the suction of the transfer mechanism 2 through the gantry loading robot 103. On the plate 2116, the output end of the second cylinder 2118 contracts, and the output end of the second cylinder 2118 drives the piston 2117 to move along the connecting tube 2114 and in the direction of the second cylinder 2118. Since the telescopic tube 2115, the connecting tube 2114 and the suction plate 2116 are connected, the suction plate 2116 generates a negative pressure, and the negative pressure generated by the suction plate 2116 fixes the battery cell on the suction plate 2116. In the prior art, the battery cell is transferred by clamping, which easily causes damage to the battery cell. Transferring by the suction plate 2116 can reduce the damage to the battery cell. Furthermore, a second motor 212 is provided on the placement block 2112, and the output end of the second motor 212 is connected to the connecting tube 2114. A spring 1 213 is provided on the outer side of the telescopic tube 2115, and the two ends of the spring 1 213 are respectively connected to the suction plate 2116 and the connecting tube 2114. When the second motor 212 rotates, the output end of the second motor 212 drives the connecting tube 2114 to rotate. When the suction plate 2116 generates negative pressure, the piston 2117 continuously moves along the direction of the second cylinder 2118, causing the telescopic tube 2115 to contract. At this time, the suction plate 2116 on the telescopic tube 2115 and the battery cell will move downward synchronously, causing the battery to The core enters the inlet and outlet groove 2113. When the motor 212 rotates, the telescopic tube 2115, the suction plate 2116 and the battery core rotate synchronously, so that the battery core is transferred to the bottom of the inlet and outlet groove 2113. When the cylinder 2118 pushes the piston 2117, the negative pressure on the suction plate 2116 disappears, so that the battery core on the suction plate 2116 is unloaded. When the transfer mechanism 2 on the linear track 202 transfers the battery core to the transfer mechanism 2 on the curved track 201, the transfer mechanism 2 on the linear track 202 rotates and unloads through the suction plate 2116, so that the battery core falls on the suction plate 2116 of the transfer mechanism 2 on the curved track 201, as shown in FIG. Figure 3 As shown, the transfer is realized, wherein the transfer mechanism 2 on the straight track 202 transfers the battery cell to the heating device 101, and transfers the heated battery cell, both of which are carried out through the suction plate 2116, to realize loading and unloading, and the transfer mechanism 2 on the curved track 201 transfers the battery cell to the hot pressing device 102 and transfers the hot pressed battery cell to the gantry unloading manipulator 104, also through the suction plate 2116; Furthermore, a cylinder 1 214 is provided on the support seat 203, and the output end of the cylinder 1 214 is connected to the bracket 2111. The transfer mechanism 2 on the linear track 202 delivers the battery cell to the heating device 101, and the bracket 2111 is pushed to move by the cylinder 1 214. The bracket 2111 is synchronously moved together with the battery cell, so that the battery cell is pushed into the heating device 101, and then the piston 2117 and the output end of the motor 2 212 are pushed to rotate by the cylinder 2 2118, so that the battery cell is transferred from the bottom of the inlet and outlet groove 2113 to the heating device 101. When the battery cell in the heating device 101 is transferred, the piston 2117 is driven to move toward the position of the cylinder 2 2118 by the cylinder 2 2118 and generate negative pressure, so that the battery cell in the heating device 101 is adsorbed and transferred, and the transfer mechanism 2 on the curved track 201 is the same; Furthermore, the heat preservation component 215 includes a semicircular block 2151 arranged on the connecting tube 2114, a transmission shaft 2152 is rotatably arranged at the bottom of the placement block 2112, and a blocking plate 2153 is arranged on the transmission shaft 2152. When the battery cell is adsorbed by the suction plate 2116 and enters the inlet and outlet groove 2113 through the contraction of the telescopic tube 2115, when the motor 212 drives the connecting tube 2114 to rotate, the semicircular block 2151 on the connecting tube 2114 rotates synchronously, and the semicircular block 2151 blocks the top of the inlet and outlet groove 2113, wherein the blocking plate 2153 blocks the bottom of the inlet and outlet groove 2113, so that the inlet and outlet groove 2113 is in a closed space. At this time, the battery cell is in a closed space. The transfer mechanism 2 on the curved track 201 insulates the battery cell through the closed space, so that the temperature of the heated battery cell decreases slowly, reducing the heat consumption of the battery cell after heating and during transfer. At the same time, the heating device 101 usually heats the battery cell to between 60 and 80 degrees when heating the battery cell. The battery cell needs to be preheated before hot pressing, and the preheating temperature is between 60 and 80 degrees. The heat loss of the battery cell during the transfer process is reduced by this insulation measure. After the battery cell is heated and transferred, the heat consumption of the battery cell decreases linearly, which will prolong the preheating time and reduce the work efficiency. Furthermore, an extension portion 2154 is provided on the blocking plate 2153, an arc groove 2155 is provided in the placement block 2112, the extension portion 2154 is slidably provided in the arc groove 2155, an air bag 2156 is provided in the inlet and outlet groove 2113, the air bag 2156 is communicated with the arc groove 2155, when the blocking plate 2153 rotates and fits with the arc groove 2155, the air in the arc groove 2155 is squeezed into the air bag 2156, so that the air bag 2156 is inflated, and a closed space can be formed by the cooperation of the semicircular block 2151, the inlet and outlet groove 2113 and the blocking plate 2153, and the heat preservation effect of the closed space is improved by the air bag 2156; The battery cells are transferred to the heating device 101 through the transfer mechanism 2 on the straight track 202, and the heated battery cells are transferred to the transfer mechanism 2 on the curved track 201. The battery cells are insulated by the transfer mechanism 2 on the curved track 201. The insulation measure reduces the heat loss of the battery cells during the transfer process, thereby improving the working efficiency of hot pressing. The battery cells are then transferred to the hot pressing device 102 through the transfer mechanism 2 on the curved track 201, and finally the battery cells in the hot pressing device 102 are transferred to the gantry unloading robot 104 to realize unloading. When the battery cells are heated and hot pressed, the loading and unloading of the battery cells can be realized separately through the transfer mechanism 2. The existing method is to load and unload the battery cells by installing two loading and unloading devices. The loading and unloading can be realized separately through the transfer mechanism 2, which can reduce costs.

[0030] Example 2, the fully automatic battery core heating and hot pressing device 102 provided in Example 1 is further optimized, specifically, as follows Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, a gear 216 is provided on the transmission shaft 2152, and a rack 217 is provided on the outer side of the gear 216. The rack 217 and the gear 216 are adapted to each other. When the rack 217 moves upward, the gear 216 rotates, and the gear 216 drives the transmission shaft 2152 to rotate synchronously. The transmission shaft 2152 drives the blocking plate 2153 to rotate and unfold and release the blocking of the inlet and outlet groove 2113. At this time, the extension part 2154 on the blocking plate 2153 is separated from the arc groove 2155, so that the arc groove 2155 is connected to the outside. At this time, the airbag 2156 is connected to the outside and shrinks. Because the battery core should not be directly exposed to the outside air after hot pressing. , mainly to prevent the performance of the diaphragm from being damaged. When the hot-pressed battery cell is transported by the transport mechanism 2 on the curved track 201, the battery cell is adsorbed by the suction plate 2116 and the telescopic tube 2115 is contracted in the inlet and outlet groove 2113. As the airbag 2156 contracts, the space in the inlet and outlet groove 2113 becomes larger. The motor 212 is driven to drive the connecting tube 2114, the telescopic tube 2115, the suction plate 2116 and the battery cell to rotate synchronously, so that the battery cell rotates in the inlet and outlet groove 2113 for uniform heat dissipation. The heat of the hot-pressed battery cell is reflected by the inner wall of the inlet and outlet groove 2113, so that the battery cell slowly and evenly dissipates heat to prevent the battery cell from being damaged. Further, the synchronous adjustment component 218 includes a spiral groove 2181 arranged on the rotating shaft 206, a synchronous plate 1 2182 is arranged on the rotating shaft 206, a synchronous plate 2183 is slidably arranged in the synchronous plate 1 2182, a spring 2184 is arranged on the corresponding surfaces of the synchronous plate 1 2182 and the synchronous plate 2 2183, a convex block 2185 is arranged on the synchronous plate 1 2182, and the convex block 2185 is slidably arranged on the spiral groove 2181, and the rack 217 is arranged on the synchronous plate 2 2183. When the transfer mechanism 2 on the curved track 201 transfers the heated battery cell, when the wheel 209 encounters the turning point of the curved track 201, the wheel 209 Slowly rotate 90 degrees, then the rotating shaft 206 rotates synchronously, the spiral groove 2181 on the rotating shaft 206 squeezes the protrusion 2185, the protrusion 2185 moves along the spiral groove 2181 and moves upward, then the protrusion 2185, the synchronous plate 1 2182 and the synchronous plate 2183 move upward synchronously, then the rack 217 on the synchronous plate 2183 moves upward synchronously, the rack 217 drives the gear 216 to rotate, the gear 216 drives the transmission shaft 2152 to rotate, the transmission shaft 2152 drives the blocking plate 2153 to rotate and unfold, wherein the transfer mechanism 2 on the linear track 202, when working, the blocking plate 2153 of the transfer mechanism 2 is always in the unfolded state; Furthermore, a guide block 2186 is provided on the second synchronous plate 2183, and a strip groove 2187 is provided on the bracket 2111. The guide block 2186 is slidably provided on the strip groove 2187, and the guide block 2186 is guided by the strip groove 2187, and the second synchronous plate 2183 is guided during displacement to prevent the second synchronous plate 2183 from deviating during displacement. When the cylinder 1 214 drives the bracket 2111 to displace, the strip groove 2187 on the bracket 2111 drives the second synchronous plate 2183 to displace synchronously, wherein the second spring 2184 is used to drive the second synchronous plate 2183 to reset; When the transfer mechanism 2 on the curved track 201 is transferring the battery cells, the battery cells are kept warm by the transfer mechanism 2 when the transfer mechanism 2 moves linearly on the curved track 201; when the transfer mechanism 2 turns on the curved track 201, the blocking plate 2153 on the transfer mechanism 2 is unfolded and the airbag 2156 is contracted to enlarge the space in the inlet and outlet slot 2113; when the hot-pressed battery cells are transferred, the motor 212 is driven to rotate to slowly dissipate the heat in the inlet and outlet slot 2113 to prevent the battery cells from being damaged.

[0031] The use process of the fully automatic battery core heating and hot pressing device 102 provided by the present invention is as follows: When in use, the gantry loading robot 103 places the battery cell on the transfer mechanism 2 on the linear track 202, transfers the battery cell to the heating device 101 through the transfer mechanism 2 on the linear track 202, and finally transfers the heated battery cell to the transfer mechanism 2 on the curved track 201, so that the heated battery cell falls on the suction plate 2116. At this time, the output end of the cylinder 2118 contracts, and the output end of the cylinder 2118 drives the piston 2117 to move along the connecting pipe 2114 and in the direction of the cylinder 2118. Because the telescopic tube 2115, the connecting pipe 2114 and the suction plate 2116 are connected, the suction plate 2116 generates negative pressure, and the negative pressure generated by the suction plate 2116 fixes the battery cell on the suction plate 2116. At this time, the suction plate 2116 on the telescopic tube 2115 and the battery cell will move downward synchronously, so that the battery cell enters the inlet and outlet groove 2113. At this time, the output end of the motor 212 drives the connecting tube 2114 to rotate, and the semicircular block 2151 on the connecting tube 2114 and the telescopic tube 2115 rotate synchronously. The semicircular block 2151 blocks the top of the inlet and outlet groove 2113, wherein the blocking plate 2153 blocks the bottom of the inlet and outlet groove 2113, so that the inlet and outlet groove 2113 is in a closed space. At this time, the battery cell is in a closed space, and when the blocking plate 2153 rotates and adapts to the arc groove 2155, the air in the arc groove 2155 is squeezed to the air The airbag 2156 is inflated, and the battery cell is kept warm through the formed closed space. When the transfer mechanism 2 on the curved track 201 transfers the heated battery cell, when the wheel 209 encounters the turning point of the curved track 201, the wheel 209 slowly rotates 90 degrees. At this time, the rotating shaft 206 rotates synchronously, and the spiral groove 2181 on the rotating shaft 206 squeezes the protrusion 2185. The protrusion 2185 moves along the spiral groove 2181 and moves upward. At this time, the protrusion 2185, the synchronous plate 1 2182 and the synchronous plate 2183 move upward synchronously. At this time, the rack 217 on the synchronous plate 2183 moves upward synchronously, and the rack 217 drives the gear 216 to rotate. 16 drives the transmission shaft 2152 to rotate, and the transmission shaft 2152 drives the sealing plate 2153 to rotate and expand, and finally the hot-pressed battery cell is adsorbed by the suction plate 2116 and the telescopic tube 2115 is contracted in the inlet and outlet groove 2113. As the airbag 2156 contracts, the space in the inlet and outlet groove 2113 becomes larger, and the motor 212 is driven to drive the connecting tube 2114, the telescopic tube 2115, the suction plate 2116 and the battery cell to rotate synchronously, so that the battery cell rotates in the inlet and outlet groove 2113 for uniform heat dissipation, and the heat of the battery cell after hot pressing is reflected by the inner wall of the inlet and outlet groove 2113, so that the battery cell slowly and evenly dissipates the heat to prevent the battery cell from being damaged, and finally the heat-dissipated battery cell is unloaded through the gantry unloading robot 104.
