Description

Technical Field

[0001] The present invention relates to the field of battery manufacturing, and more particularly, to a fully automatic cell heating and hot pressing device. Background Art

[0002] A cell is the core component of a battery and is the key structural unit for the battery to store and release electrical energy. It is the basis for constructing a battery and is usually composed of a positive electrode material, a negative electrode material, an electrolyte, a separator, etc., and is assembled through a specific process. During the manufacturing process of the cell, the positive electrode sheet, the negative electrode sheet, and the separator are assembled together by winding or laminating, and through a cell heating device and a cell hot pressing device, the internal structure and performance of the cell are optimized to ensure the efficiency and safety of the battery during use.

[0003] For example: "A cell heating device and method" disclosed in the Chinese invention patent (application number: 202310548917.4), its specification discloses: including at least one heating unit, the heating unit includes: a plurality of heating modules, each heating module includes a coil, a skeleton, and a first magnetic conductor, the coil is wound around the skeleton, and the first magnetic conductor is inserted into the skeleton; and a second magnetic conductor, the second magnetic conductor is respectively connected to the ends of the first magnetic conductors of the plurality of heating modules; "A cell hot pressing device" disclosed in the Chinese utility model patent (application number: 202321089781.7), its specification discloses: including a hot pressing support, a hot pressing support plate is provided on the hot pressing support, a hot pressing cylinder is further provided on the hot pressing support above the hot pressing support plate, and a hot pressing plate parallel to the hot pressing support plate is installed on the piston rod of the hot pressing cylinder; a hot pressing transfer assembly for transferring the cell carrying unit to the hot pressing support plate is provided on the hot pressing support; a hot pressing docking assembly for docking with two winding rollers of the cell carrying platform to output the hot pressed cell through a conveyor belt from the cell carrying unit is further provided on the hot pressing support.

[0042] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] As described in the background art, the existing battery cell heating device and battery cell hot pressing device are two separate devices. The separate heating and hot pressing devices need to be operated in steps, and the battery cells need to be transferred between different devices, resulting in cumbersome work and high costs.

[0044] To solve this technical problem, the present invention provides a fully automatic battery cell heating and hot pressing device, which is applied to battery manufacturing.

[0045] Specifically, please refer to Figures 1 - 14 , the fully automatic battery cell heating and hot pressing device specifically includes: a base 1, a heating device 101 arranged on the base 1, a hot pressing device 102 arranged on the base 1, a gantry loading manipulator 103 arranged on the base 1, and a gantry unloading manipulator 104 arranged on the base 1, and further includes two groups of transfer mechanisms 2 arranged on the base 1;

[0046] The transfer mechanism 2 includes a curved track 201 arranged on the base 1, a linear track 202 arranged on the base 1, support seats 203 respectively arranged on the curved track 201 and the linear track 202, clamping blocks 204 rotatably arranged at the bottoms of the support seats 203, the clamping blocks 204 respectively sliding on the curved track 201 and the linear track 202, balls 205 rotatably arranged on the clamping blocks 204, the balls 205 respectively being adapted to the curved track 201 and the linear track 202, a rotating shaft 206 rotatably arranged on the support seat 203, a fixed seat 207 arranged on the rotating shaft 206, a first motor 208 arranged on the fixed seat 207, a wheel 209 rotatably arranged on the fixed seat 207, the output end of the first motor 208 being connected to the wheel 209, a bracket 2111 slidably arranged on the base 1, a placing block 2112 arranged on the bracket 2111, a placing component 211 arranged on the base 1, a heat preservation component 215 arranged on the base 1, and a synchronous adjustment component 218 arranged on the base 1.

[0047] The full-automatic battery cell heating and hot pressing device 102 provided by the present invention is to solve the problem that in the prior art, the existing battery cell heating device 101 and the battery cell hot pressing device 102 are two devices, and the separate heating and hot pressing devices 102 need to be operated step by step, and the battery cells need to be transferred between different devices, the work is relatively cumbersome and the cost is relatively high. Through the arranged transfer mechanism 2, the feeding and discharging during the heating and hot pressing of the battery cells by the transfer mechanism 2 reduce the transfer between different devices and improve the work efficiency;

[0048] Through the arranged transfer mechanism 2, the heated battery cells are placed in the closed space formed by the inlet and outlet slots 2113 to keep the battery cells warm, which can improve the hot pressing effect and quality;

[0049] Through the arranged transfer mechanism 2, the hot-pressed battery cells are rotated in the inlet and outlet slots 2113 to achieve uniform and slow heat dissipation, solving the problem that in the prior art, the hot-pressed battery cells are directly exposed to the air for heat dissipation, which is easy to cause damage.

[0050] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0051] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0052] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0053] Example 1, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 , Figure 13 and Figure 14 shown, a fully automatic battery cell heating and hot pressing device 102, its placement component 211 includes an inlet and outlet groove 2113 arranged in a placement block 2112, a connecting pipe 2114 is rotatably arranged in the inlet and outlet groove 2113, a telescopic pipe 2115 is fixedly penetrated on the connecting pipe 2114, a suction plate 2116 is arranged on the telescopic pipe 2115, the suction plate 2116 is communicated with the telescopic pipe 2115. When a first motor 208 rotates, the output end of the first motor 208 drives a wheel 209 to rotate synchronously. At the same time, the wheel 209 rotates and displaces, and the wheel 209 drives a fixed seat 207, a rotating shaft 206 and a support seat 203 to displace synchronously. The support seat 203 drives a ball 205 on a clamping block 204 to rotate and displace along a curved track 201, so that the whole transfer mechanism 2 displaces along the curved track 201. Similarly, the transfer mechanism 2 on a linear track 202 has the same working principle as the transfer mechanism 2 on the curved track 201. The transfer mechanism 2 on the linear track 202 is used to transfer the battery cell into a heating device 101, heat the battery cell through the heating device 101, and is used to transfer the heated battery cell from the heating device 101 to the transfer mechanism 2 on the curved track 201, as Figure 3 shown, the transfer mechanism 2 on the curved track 201 is used to transfer the heated battery cell into a hot pressing device 102. The ball 205 contacts the linear track 202 and the curved track 201, which can reduce friction and make the friction force of the transfer mechanism 2 smaller when it displaces;

[0054] Further, a piston 2117 is slidably arranged inside the connecting pipe 2114, and a second cylinder 2118 is arranged on the placing block 2112. The output end of the second cylinder 2118 is connected to the piston 2117. In the initial state, the gantry loading manipulator 103 is used to transfer the battery cells to the transfer mechanism 2 on the linear track 202, and the gantry unloading manipulator 104 is used to unload the battery cells after hot pressing. During use, the gantry loading manipulator 103 places the battery cells on the transfer mechanism 2 on the linear track 202, and transfers the battery cells to the suction plate 2116 of the transfer mechanism 2 through the gantry loading manipulator 103. The output end of the second cylinder 2118 contracts, and the output end on the second cylinder 2118 drives the piston 2117 to displace along the inside of the connecting pipe 2114 and towards the direction of the second cylinder 2118. Since the telescopic pipe 2115, the connecting pipe 2114, and the suction plate 2116 are connected, a negative pressure is generated on the suction plate 2116. The negative pressure generated on the suction plate 2116 fixes the battery cells on the suction plate 2116. Currently, the battery cells are transferred by clamping, and the clamping method is likely to cause damage to the battery cells. Transferring through the suction plate 2116 can reduce the damage to the battery cells;

[0055] Further, a second motor 212 is arranged on the placing block 2112. The output end of the second motor 212 is connected to the connecting pipe 2114. A first spring 213 is arranged outside the telescopic pipe 2115. Both ends of the first spring 213 are respectively connected to the suction plate 2116 and the connecting pipe 2114. When the second motor 212 rotates, the output end of the second motor 212 drives the connecting pipe 2114 to rotate. When a negative pressure is generated on the suction plate 2116, since the piston 2117 continuously displaces towards the direction of the second cylinder 2118, the telescopic pipe 2115 contracts. At this time, the suction plate 2116 on the telescopic pipe 2115 together with the battery cells will move downward synchronously, so that the battery cells enter the access slot 2113. When the second motor 212 rotates, the telescopic pipe 2115, the suction plate 2116, and the battery cells rotate synchronously, so that the battery cells are transferred below the access slot 2113. When the second cylinder 2118 pushes the piston 2117, the negative pressure on the suction plate 2116 disappears at this time, so that the battery cells on the suction plate 2116 are unloaded. When the transfer mechanism 2 on the linear track 202 transfers the battery cells 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 cells fall onto the suction plate 2116 of the transfer mechanism 2 on the curved track 201, as Figure 3 shown, to achieve transfer. When the transfer mechanism 2 on the linear track 202 transfers the battery cells into the heating device 101 and transfers the heated battery cells, it is all carried out through the suction plate 2116 to achieve loading and unloading. When the transfer mechanism 2 on the curved track 201 transfers the battery cells to the hot pressing device 102 and transfers the hot-pressed battery cells to the gantry unloading manipulator 104, it is also transferred through the suction plate 2116;

[0056] Further, a first cylinder 214 is provided on the support base 203. The output end of the first cylinder 214 is connected to the bracket 2111. The transfer mechanism 2 on the linear track 202 sends the battery cell into the heating device 101. By pushing the bracket 2111 to displace with the first cylinder 214, the battery cell on the bracket 2111 is displaced synchronously, so that the battery cell is pushed into the heating device 101. Then, by pushing the piston 2117 and the output end of the second motor 212 to rotate with the second cylinder 2118, the battery cell is transferred from the bottom of the inlet and outlet slot 2113 into the heating device 101. When transferring the battery cell in the heating device 101, the piston 2117 is driven by the second cylinder 2118 to displace towards the position of the second cylinder 2118 and generate negative pressure, adsorbing the battery cell in the heating device 101 and transferring it. The transfer mechanism 2 on the curved track 201 is the same in principle;

[0057] Further, the heat preservation component 215 includes a semi-circular block 2151 arranged on the connecting pipe 2114. A transmission shaft 2152 is rotatably arranged at the bottom of the placing block 2112. A sealing 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 slot 2113 through the contraction of the telescopic pipe 2115, when the second motor 212 drives the connecting pipe 2114 to rotate, the semi-circular block 2151 on the connecting pipe 2114 rotates synchronously, and the top of the inlet and outlet slot 2113 is blocked by the semi-circular block 2151. The sealing plate 2153 blocks the bottom of the inlet and outlet slot 2113, so that the inlet and outlet slot 2113 is in a closed space. At this time, the battery cell is in the closed space. For the transfer mechanism 2 on the curved track 201, the battery cell is heat-preserved through the closed space, so that the temperature of the heated battery cell drops slowly, reducing the heat consumption of the battery cell after heating and during transfer. At the same time, when the heating device 101 heats the battery cell, the battery cell is usually heated to between 60 and 80 degrees. The battery cell needs to be preheated before hot pressing, and the preheating temperature is between 60 and 80 degrees. Through this heat preservation measure, the heat loss of the battery cell during transfer is reduced. Because after the battery cell is heated and during transfer, the heat consumption of the battery cell decreases linearly, which will make the preheating time longer and lead to a decrease in work efficiency;

[0058] Further, an extension part 2154 is arranged on the sealing plate 2153. An arc-shaped groove 2155 is arranged in the placing block 2112. The extension part 2154 is slidably arranged in the arc-shaped groove 2155. An air bag 2156 is arranged in the inlet and outlet slot 2113. The air bag 2156 is communicated with the arc-shaped groove 2155. When the sealing plate 2153 rotates and fits with the arc-shaped groove 2155, the air in the arc-shaped groove 2155 is squeezed into the air bag 2156, making the air bag 2156 inflated. Since the semi-circular block 2151, the inlet and outlet slot 2113 and the sealing plate 2153 can cooperate to form a closed space, the heat preservation effect of the closed space is improved through the air bag 2156;

[0059] 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.

[0060] 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 , Figure 9 and Figure 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.

[0061] Further, the synchronization adjustment component 218 includes a spiral groove 2181 provided on the rotating shaft 206. A first synchronization plate 2182 is provided on the rotating shaft 206. A second synchronization plate 2183 is slidably arranged within the first synchronization plate 2182. A second spring 2184 is provided on the corresponding surfaces of the first synchronization plate 2182 and the second synchronization plate 2183. A convex block 2185 is provided on the first synchronization plate 2182. The convex block 2185 is slidably arranged on the spiral groove 2181. The rack 217 is provided on the second synchronization plate 2183. When the transfer mechanism 2 on the curved track 201 transfers the heated battery cells, when the wheel 209 encounters the turning of the curved track 201, the wheel 209 slowly rotates 90 degrees. At this time, the rotating shaft 206 rotates synchronously. The spiral groove 2181 on the rotating shaft 206 presses the convex block 2185. The convex block 2185 displaces along the spiral groove 2181 and displaces upward. At this time, the convex block 2185, the first synchronization plate 2182, and the second synchronization plate 2183 displace upward synchronously. At this time, the rack 217 on the second synchronization plate 2183 displaces 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 sealing plate 2153 to rotate and unfold. Among them, for the transfer mechanism 2 on the linear track 202, during operation, the sealing plate 2153 of the transfer mechanism 2 is always in the unfolded state;

[0062] Further, a guide block 2186 is provided on the second synchronization plate 2183. A strip-shaped groove 2187 is provided on the bracket 2111. The guide block 2186 is slidably arranged in the strip-shaped groove 2187. The strip-shaped groove 2187 guides the guide block 2186 to guide the displacement of the second synchronization plate 2183 to prevent the second synchronization plate 2183 from deviating during displacement. When the first cylinder 214 drives the bracket 2111 to displace, the strip-shaped groove 2187 on the bracket 2111 drives the second synchronization plate 2183 to displace synchronously. Among them, the second spring 2184 is used to drive the second synchronization plate 2183 to reset;

[0063] When the transfer mechanism 2 on the curved track 201 transfers the battery cells, when the transfer mechanism 2 linearly displaces on the curved track 201, the transfer mechanism 2 keeps the battery cells warm. When the transfer mechanism 2 turns on the curved track 201, the sealing plate 2153 on the transfer mechanism 2 unfolds, and at the same time, the airbag 2156 contracts, making the space in the access slot 2113 larger. When transferring the hot-pressed battery cells, by driving the second motor 212 to rotate, the hot-pressed battery cells are slowly cooled in the access slot 2113 to prevent the battery cells from being damaged.

[0064] The usage process of the full-automatic battery cell heating and hot-pressing device 102 provided by the present invention is as follows:

[0065] During use, the gantry loading manipulator 103 places the battery cell on the transfer mechanism 2 on the linear track 202. The transfer mechanism 2 on the linear track 202 transfers the battery cell into the heating device 101, and finally transfers the heated battery cell to the transfer mechanism 2 on the bending track 201, causing the heated battery cell to fall onto the suction plate 2116. At this time, 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 pipe 2114 and towards the direction of the second cylinder 2118. Since the telescopic pipe 2115, the connecting pipe 2114, and the suction plate 2116 are connected, a negative pressure is generated on the suction plate 2116. The negative pressure generated by the suction plate 2116 fixes the battery cell on the suction plate 2116. At the same time, the telescopic pipe 2115 contracts, and at this time, the suction plate 2116 on the telescopic pipe 2115 and the battery cell will move downward synchronously, causing the battery cell to enter the access slot 2113. At this time, the output end of the second motor 212 drives the connecting pipe 2114 to rotate, and the semi-circular block 2151 on the connecting pipe 2114 and the telescopic pipe 2115 rotate synchronously. The top of the access slot 2113 is blocked by the semi-circular block 2151, and the bottom of the access slot 2113 is blocked by the blocking plate 2153, making the access slot 2113 in a closed space. At this time, the battery cell is in a closed space. When the blocking plate 2153 rotates and fits with the arc-shaped groove 2155, the air in the arc-shaped groove 2155 is squeezed into the airbag 2156, causing the airbag 2156 to inflate, and then heat-insulating the battery cell through the formed closed space. When the transfer mechanism 2 on the bending track 201 transfers the heated battery cell, when the wheel 209 encounters the turning point of the bending 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 convex block 2185. The convex block 2185 moves along the spiral groove 2181 and moves upward. At this time, the convex block 2185, the first synchronous plate 2182, and the second synchronous plate 2183 move upward synchronously. At this time, the rack 217 on the second synchronous plate 2183 moves upward synchronously. The rack 217 drives the gear 216 to rotate, and the gear 216 drives the transmission shaft 2152 to rotate. The transmission shaft 2152 drives the blocking plate 2153 to rotate and unfold. Finally, the hot-pressed battery cell is adsorbed by the suction plate 2116 and the telescopic pipe 2115 contracts in the access slot 2113. Due to the contraction of the airbag 2156, the space in the access slot 2113 becomes larger. By driving the second motor 212 to drive the connecting pipe 2114, the telescopic pipe 2115, the suction plate 2116, and the battery cell to rotate synchronously, the battery cell rotates in the access slot 2113 for uniform heat dissipation. The heat after hot-pressing the battery cell is reflected by the inner wall of the access slot 2113, causing the battery cell to dissipate heat slowly and evenly, preventing the battery cell from being damaged. Finally, the cooled battery cell is unloaded by the gantry unloading manipulator 104.
