Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing equipment, and in particular to a lithium battery lateral transfer trolley and lithium battery drying equipment. Background Art

[0002] With the rapid development of the lithium battery industry, lithium batteries are widely used, and their performance is crucial. Moisture has a huge impact on the performance of lithium batteries. In the production process of lithium batteries, the water content of lithium batteries must be strictly controlled. Loss of control or coarsening of moisture will lead to a significant deterioration in the performance of lithium batteries.

[0003] Therefore, soft-pack batteries need to be baked after winding and before liquid injection. Generally, the battery is placed in the tray by a loader, and then the battery in the tray is moved to the fixture of the drying furnace by the RGV trolley. After the furnace door is closed to form a sealed cavity, the battery in the fixture is baked by vacuuming and heating. The existing RGV trolley is composed of a pallet conveyor line, a walking track, a push-pull fixture mechanism, a pallet positioning mechanism, a battery transfer robot, etc. The pallet conveyor line is set below or at the bottom of the RGV trolley, and the pallet is transported to the pallet positioning mechanism through the bottom pallet conveyor line for positioning, and then the fixture in the oven is pulled open by the fixture push-pull mechanism to position it on the RGV trolley. The battery transfer robot can grab the battery to realize the transfer of the battery in the pallet and fixture.

[0004] However, the design of the pallet conveyor line at the bottom of the RGV cart will increase the overall height. In actual use, the factory is generally planned in length rather than height. Therefore, the increase in the overall height will reduce the number of baking layers in the oven, thereby resulting in a decrease in the number of baked batteries and an increase in the overall cost. In addition, the Z-axis robot for transferring batteries is a single-axis, which will cause the Z-axis robot to be much higher than other equipment, making it inconvenient to grab the batteries and reducing the transfer efficiency, which is not conducive to production. Summary of the invention

[0005] The object of the present invention is to provide a lithium battery side-transfer trolley which can move trays in and out from the side to increase the number of layers baked by lithium battery drying equipment, thereby improving production efficiency and reducing production costs.

[0006] Another object of the present invention is to provide a lithium battery drying device which can move trays in and out from the side and has high production efficiency and low production cost.

[0007] In order to achieve the above-mentioned purpose, the lithium battery lateral transfer trolley provided by the present invention is suitable for loading and unloading the clamps in the drying equipment, and comprises a mobile frame, a bearing platform, a clamp push-pull mechanism, a lifting drive mechanism, a tray lateral docking mechanism, a transfer manipulator and a translation drive mechanism; the mobile frame is provided with a first docking interface on one side along the transverse direction and a second docking interface on the other side opposite to the first docking interface; the bearing platform is arranged on the mobile frame; the clamp push-pull mechanism is arranged on the bearing platform and can drive the clamp to move so as to enter and exit the first docking interface A pair of interfaces; the lifting drive mechanism is arranged on the mobile frame and can drive the load-bearing platform to move vertically; the tray lateral docking mechanism is arranged on the mobile frame and is located on one side of the longitudinal direction of the load-bearing platform, and is used to drive the tray in and out of the second pair of interfaces; the transfer robot is slidably arranged on the mobile frame, and is used to grab the lithium battery in one of the fixture and the tray located in the mobile frame and transfer it to the other; the translation drive mechanism is arranged on the mobile frame, and is used to drive the transfer robot to move longitudinally.

[0008] Compared with the prior art, the present invention sets a first docking interface and a second docking interface on opposite sides of the mobile frame, and sets a clamp push-pull mechanism, and uses the clamp push-pull mechanism to receive or output the clamp from the first docking interface, so that the clamp can enter and exit the mobile frame, and uses the lifting drive mechanism to drive the load platform to rise and fall, so that the clamp push-pull mechanism can dock with clamps at different heights; in addition, a tray lateral docking mechanism is set on one side of the load platform, and the tray lateral docking mechanism is used to receive or output the tray from the second docking interface, so that the tray can enter and exit the mobile frame; and a transfer manipulator is set between the load platform and the tray lateral docking mechanism, and the transfer manipulator is used to clamp the lithium battery, so that the lithium battery can be transferred between the tray and the clamp. Therefore, the entire trolley can transfer the battery on the tray to the clamp, and then output the clamp from one side; or transfer the battery on the clamp to the tray, and then output the tray from the other side. Therefore, the present invention can move the tray and the clamp in and out from the side, avoiding the layout of conveying the tray surface from the bottom to the top and occupying the limited height space of the factory building, thereby increasing the number of baking layers of the lithium battery drying equipment, and then increasing the number of baked batteries, greatly improving production efficiency and reducing production costs.

[0009] Preferably, it further comprises a first lifting mechanism, which is arranged below the tray lateral docking mechanism to drive the tray on the tray lateral docking mechanism to lift or lower.

[0030] In order to explain the technical content, structural features and achieved effects of the present invention in detail, the following is a detailed description in conjunction with the implementation methods and the accompanying drawings.

[0031] like Figures 1 to 4As shown, the lithium battery drying device 100 of the present invention includes a lithium battery lateral transfer trolley 1, a drying device 2, a tray conveying mechanism 3, a movable guide rail 4 and a driving device 5, wherein the movable guide rail 4 extends longitudinally; the drying device 2 is arranged on one side of the movable guide rail 4, the lithium battery lateral transfer trolley 1 is movably arranged on the movable guide rail 4, and the tray conveying mechanism 3 is arranged on the other side of the movable guide rail 4 to convey the tray 300. The lithium battery lateral transfer trolley 1 includes a movable frame 11, a load platform 12, a clamp push-pull mechanism 13, a lifting drive mechanism 14, a tray lateral docking mechanism 15, a transfer manipulator 16 and a translation drive mechanism 17. The movable frame 11 is a frame, and a first docking cavity 111 and a second docking cavity 112 are arranged longitudinally in the movable frame 11. The mobile frame 11 is provided with a first docking port 11a on one side along the transverse direction and a second docking port 11b on the other side opposite to the first docking port 11a, the first docking port 11a is communicated with the first docking cavity 111, and the second docking port 11b is communicated with the second docking cavity 112. The bearing platform 12 is arranged in the first docking cavity 111 of the mobile frame 11. The clamp push-pull mechanism 13 is arranged on the bearing platform 12 and can drive the clamp 200 to move in and out of the first docking port 11a. The lifting drive mechanism 14 is arranged in the first docking cavity 111 of the mobile frame 11 and can drive the bearing platform 12 to move vertically. The tray lateral docking mechanism 15 is arranged in the second docking cavity 112 of the mobile frame 11 and is located on one side of the longitudinal direction of the bearing platform 12, and is used to drive the tray 300 to enter and exit the second docking port 11b. The transfer manipulator 16 is disposed on the mobile frame 11 in a longitudinally sliding manner, and is used to grab and transfer the lithium battery in one of the fixture 200 and the tray 300 located in the mobile frame 11 to the other. The translation drive mechanism 17 is disposed on the mobile frame 11, and is used to drive the transfer manipulator 16 to move longitudinally. The tray conveying mechanism 3 and the drying device 2 are respectively located on opposite sides of the mobile guide rail 4. The driving device 5 is used to drive the lithium battery lateral transfer trolley 1 to move, so that the first docking port 11a is docked with the fixture entrance and exit of the drying device 2, or the second docking port 11b is docked with the output end of the tray conveying mechanism 3. The driving device is disposed between the lithium battery lateral transfer trolley 1 and the mobile guide rail 4, and the driving device 5 includes a motor, a gear and a rack. The motor is disposed on the lithium battery lateral transfer trolley 1, the gear is connected to the output end of the motor, the rack is disposed on the mobile guide rail 4, and the rack is meshed with the gear.The lifting drive mechanism 14 can be driven by a motor to move the lead screw slider, and the translation drive mechanism 17 can be driven by a motor to drive a pulley and a belt. The structures of both are well known to those skilled in the art and will not be described in detail here.

[0032] See also Figures 3 to 5 The lithium battery lateral transfer vehicle 1 further includes a first lifting mechanism 6, which is located in the second docking cavity 112 and is disposed below the tray lateral docking mechanism 15 to drive the tray on the tray lateral docking mechanism 15 to lift or lower. By providing the first lifting mechanism 6, after the tray lateral docking mechanism 15 inputs the tray 300 onto the mobile frame 11, the tray 300 can be lifted, so that the tray 300 is positioned to prevent the tray 300 from accidentally shifting on the tray lateral docking mechanism 15, thereby facilitating the transfer robot 16 to grab the lithium battery and improving the accuracy of grabbing. Specifically, the first lifting mechanism 6 includes a motor 61, a screw rod 61a, a slider 61b, a slide plate 61c, a lifting plate 62 and a positioning column 63. The motor 61 is arranged on the base 151, and the output end is connected to the screw rod 61a by a pulley and a belt and drives the screw rod 61a to rotate. The screw rod 61a is arranged on the base 151, the slider 61b is threadedly connected to the screw rod 61a and fixed to the slide plate 61c, and a top column 61d is provided on the slide plate 61c, and the top column 61d is connected to the lifting plate 62. The positioning column 63 is arranged on the lifting plate 62 to position the pallet. In this way, the pallet can be quickly positioned, and the accuracy of the pallet position can be improved, so that it is convenient for the transfer robot 16 to grab the lithium battery on the pallet. In addition, the lithium battery lateral transfer trolley 1 further includes a limiting mechanism (not shown), which is arranged on one side of the first lifting mechanism 6. When the first lifting mechanism 6 drives the tray 300 to enter the second docking cavity 112, the limiting mechanism extends to prevent the tray 300 from excessively shifting, so that it is located directly above the first lifting mechanism 6. In this way, the first lifting mechanism 6 can accurately lift the tray.

[0033] For example Figure 8 and Fig. 9As shown, the tray lateral docking mechanism 15 includes a base 151, a second motor 152, a chain 153, a roller 154, a driving gear 155 and a driven gear 156. The base 151 is fixed on the mobile frame 11. Both sides of the base 151 are provided with track grooves 157 extending in the transverse direction. The rollers 154 are arranged in the track grooves 157 in a rotatable and transversely spaced manner. The driven gear 156 is coaxially connected with the rollers 154 in a one-to-one correspondence. The chain 153 is wound between the driving gear 155 and the driven gear 156. The rollers 154 protrude from the track grooves 157 so as to carry the tray. The second motor 152 is arranged on the base 151 and the output end is connected to the driving gear 155. By utilizing the second motor 152 to drive the chain 153 and the driving gear 155 to rotate, the chain 153 and the driven gear 156 can drive the roller 154 to roll, thereby achieving the goal of carrying the weight of the pallet while driving the pallet forward.

[0034] See also Figure 4 and Figure 6 The clamp push-pull mechanism 13 includes a transverse driving mechanism 131, a slide 132 and a clamp connecting mechanism 133. The slide 132 is slidably arranged on the carrier 12. The clamp connecting mechanism 133 is arranged on the slide 132 and is used to connect or disconnect the clamp. The transverse driving mechanism 131 is arranged between the carrier 12 and the slide 132, and is used to drive the slide 132 to move laterally. By using the transverse driving mechanism 131 to drive the slide 132 to approach or move away from the clamp, and then using the clamp connecting mechanism 133 to connect or disconnect the clamp, the clamp can be driven to be input or output, thereby realizing the transfer of the clamp. The transverse driving mechanism 131 includes a transverse motor 1311, two pulleys 1312, a belt 1313, a rotating shaft 1314, a gear 1315 and a rack 1316. The transverse motor 1311 is arranged on the slide and the output end is connected to one of the pulleys 1312, the other pulley 1312 is connected to the rotating shaft 1314, the belt 1313 is wound between the two pulleys 1312, the gear 1315 is connected to the rotating shaft 1314, the rack 1316 is fixedly arranged on the support platform 12, and the gear 1315 is meshed with the rack 1316. When the motor is started, the rotating shaft 1314 can be driven by the belt 1313, so that the gear 1315 rotates, and the gear 1315 interacts with the rack 1316 to make the slide as a whole move back and forth relative to the support platform 12.

[0035] Please see again Figures 4 to 7Specifically, the clamp connection mechanism 133 includes a first motor 1331, a screw rod 1332, a slider 1333 and a latch 1334. The slider 1333 is threadedly connected to the screw rod 1332, and the latch 1334 is fixedly connected to the slider 1333 through an arm. The first motor 1331 is arranged on the slide 132 and the output end is connected to the screw rod 1332 to drive the screw rod 1332 and the slider 1333, so that the latch 1334 moves and is inserted into or withdrawn from the socket 201 of the clamp. By using the first electric rod to drive the screw rod 1332 and the slider 1333, the latch 1334 can be inserted into or withdrawn from the socket 201 of the clamp to achieve connection or separation. The structure is simple and the control is very convenient. The rear section of the plug 1334 is pivotally connected with rollers 1335, and the rollers 1335 protrude from both sides of the plug 1334. When the rear section of the plug 1334 is inserted into the insertion hole 201, the rollers 1335 abut against two opposite inner walls of the insertion hole 201. By adding rollers 1335 to the plug 1334, when the front section of the plug 1334 enters the insertion hole 201, the plug 1334 can be connected to the clamp; when the rear section of the plug 1334 enters the insertion hole 201, the rollers 1335 can be stuck in the two inner walls of the insertion hole 201, so that the two are in close contact, thereby making the position of the plug 1334 relative to the insertion hole 201 more accurate. Therefore, the clamp is more accurately connected to the latch 1334, ensuring that the subsequent transfer robot 16 and the clamp can be accurately aligned, so that the battery can be accurately clamped.

[0036] For example Fig.10 and Fig.11As shown, the transfer robot 16 includes a base plate 161, a slide 162, a first transfer motor 163, a first drive screw 164, a first drive slider 165, a second transfer motor 166, a second drive screw (not shown), a second drive slider (not shown), a mounting bracket 167 and a clamping mechanism 168; the base plate 161 is connected to the output end of the translation drive mechanism 17, the slide 162 is vertically slidably arranged on the base plate 161, and the first transfer motor 163 is arranged on the slide 162 The output end is connected to the first driving screw 164, the first driving slider 165 is fixedly connected to the base plate 161 and is threadedly connected to the first driving screw 164; the second transfer motor 166 is arranged on the slide 162 and the output end is connected to the second driving screw, the second driving screw is axially parallel to the first driving screw 164, the second driving slider is fixed to the mounting bracket 167 and is threadedly connected to the second driving screw; the clamping mechanism 168 is arranged on the mounting bracket 167. By arranging the first driving screw 164 and the second driving screw, the first transfer motor 163 and the second transfer motor 166 are used to drive the first driving screw 164 and the second driving screw to rotate respectively, so that the transfer robot 16 has a double-axis lifting structure, so that the length of the transfer robot 16 in the vertical direction can be reduced, thereby reducing the overall height, making the lithium battery grabbing faster and more convenient, and improving the transfer efficiency.

[0037] like Fig.12 As shown, the pallet conveying mechanism 3 includes an upper conveying mechanism 31, a lower conveying mechanism 32 located below the upper conveying mechanism 31, a transfer device (not shown), a pallet docking mechanism 33 and a second lifting mechanism 34. The pallet docking mechanism 33 can dock with the pallet lateral docking mechanism 15 to transfer the pallet therebetween. The second lifting mechanism 34 drives the pallet docking mechanism 33 to rise and fall. The transfer device transfers the pallet on the upper conveying mechanism 31 to the lower conveying mechanism 32. The transfer device is a lift. The structure of the second lifting mechanism 34 is a cylinder. In addition, the structure of the pallet docking mechanism 33 is the same as that of the pallet lateral docking mechanism 15, which will not be described again.

[0038] Based on the above and in combination with the accompanying drawings, the working principle of the lithium battery drying device 100 of the present invention is described in detail as follows:

[0039] When the lithium batteries in the drying device 2 are dried and need to be unloaded or loaded with new lithium batteries, the lithium battery lateral transfer trolley 1 is driven by the driving device 5 to move to the side close to the drying device 2 so that the first docking port 11a is directly opposite to the exit of the drying device 2. Then, the upper conveying mechanism 31 conveys the pallet loaded with lithium batteries forward to the position directly opposite to the second docking port 11b and above the pallet docking mechanism 33. At this time, the second lifting mechanism 34 lifts the pallet docking mechanism 33, and the pallet docking mechanism 33 lifts the pallet 300 so that the pallet 300 leaves the upper conveying mechanism 31. At this time, the pallet docking mechanism 33 starts to output the pallet 300 to the second docking port 11b. At the same time, the pallet lateral docking mechanism 15 starts to receive the pallet 300, and the pallet 300 enters the second docking cavity 112. The limiting mechanism extends so that the pallet 300 does not move after reaching the position. At this time, the first lifting mechanism 6 lifts the pallet 300. At the same time, in the first docking chamber 111, the transverse driving mechanism 131 drives the slide 132 to move horizontally and enter the drying device 2 from the first docking port 11a. At this time, the lifting driving mechanism 14 drives the support platform 12 to move in the vertical direction so that the support platform 12 and the clamp 200 are at the same horizontal height or on the same layer. Then, the clamp connection mechanism 133 is started, the first motor 1331 drives the screw rod 1332, the screw rod 1332 drives the slider 1333 to move, the slider 1333 drives the latch 1334 to move, and the front section of the latch 1334 is inserted into the socket 201 of the clamp. At this time, the transverse driving mechanism 131 drives the slide 132 to slide and return to the first docking chamber 111. At this time, the first motor 1331 is started again to drive the rear section of the latch 1334 to be inserted into the socket 201 of the clamp 200, so that the roller 1335 is tightly stuck in the socket 201 of the clamp 200, thereby positioning the clamp 200. Afterwards, the translation drive mechanism 17 drives the transfer robot 16 to move above the first docking cavity 111. The transfer robot 16 is started, and the first transfer motor 163 and the second transfer motor 166 are started respectively, so that the clamp mechanism 168 is moved close to the clamp 200 through a dual-axis drive. Then the clamp mechanism 168 clamps the lithium battery. Thereafter, the transfer robot 16 transfers the lithium battery to the tray of the second docking cavity 112, and at the same time, the lithium battery on the tray 300 is clamped and transferred back to the clamp 200 in the first docking cavity 111.After the transfer of the lithium battery is completed, the first lifting mechanism 6 lowers the tray 300 onto the tray lateral docking mechanism 15, and the tray lateral docking mechanism 15 transports the tray from the second docking port 11b back to the tray conveying mechanism 3. At the same time, the lateral driving mechanism 131 drives the clamp 200 to enter the drying device 2 again, and then the clamp connection mechanism 133 releases the clamp, so that the clamp 200 stays in the drying device 2 for drying. In this way, the lithium batteries on the tray 300 conveying mechanism 3 can be continuously transferred to the drying device 2 for drying, and the lithium batteries on the drying device 2 can be unloaded to the tray conveying mechanism 3 for unloading.

[0040] Compared with the prior art, the present invention sets a first docking port 11a and a second docking port 11b on opposite sides of the mobile frame 11, and sets a clamp push-pull mechanism 13, which receives or outputs the clamp from the first docking port 11a, so that the clamp can enter and exit the mobile frame 11, and uses a lifting drive mechanism 14 to drive the load platform 12 to rise and fall, so that the clamp push-pull mechanism 13 can dock with clamps at different heights; in addition, a tray lateral docking mechanism 15 is set on one side of the load platform 12, and the tray lateral docking mechanism 15 is used to receive or output the tray from the second docking port 11b, so that the tray can enter and exit the mobile frame 11; and a transfer robot 16 is set between the load platform 12 and the tray lateral docking mechanism 15, and the transfer robot 16 is used to clamp the lithium battery, so that the lithium battery can be transferred between the tray 300 and the clamp 200. Therefore, the entire trolley can transfer the batteries on the tray 300 to the fixture 200, and then output the fixture 200 from one side; or transfer the batteries on the fixture 200 to the tray 300, and then output the tray 300 from the other side. Therefore, the present invention can move the tray 300 and the fixture 200 in and out from the side, avoiding the layout of conveying the tray surface from the bottom to the top to occupy the limited height space of the factory, so that the number of baking layers of the lithium battery drying equipment 100 can be increased, and then the number of baked batteries can be increased, which greatly improves production efficiency and reduces production costs.

[0041] The structure of the drying device 2 involved in the lithium battery drying device 100 of the present invention is well known to those skilled in the art and will not be described in detail herein.

[0042] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
