Description

Technical Field

[0001] This invention relates to a lithium battery drying equipment, and more particularly to a loading and unloading docking device for lithium battery drying. Background Technology

[0002] Before the lithium iron phosphate battery is filled with electrolyte, the cells need to be baked to remove moisture. Specifically, a push-pull mechanism is used to pull the drying fixture out of the sealed furnace. Then, the drying fixture is opened, the lithium battery is placed inside, and the drying fixture clamps the lithium battery. Finally, the push-pull mechanism pushes the drying fixture back into the sealed furnace. Currently, on lithium battery baking production lines, the drying fixture, which has its own clamping function, needs to be transferred to a special station to be opened after being pulled out of the furnace by the push-pull mechanism. Only then can a crane robot pick up the cell and place it on the drying fixture, which then flows back into the furnace cavity. This production method involves many steps, the drying fixture transfer process is cumbersome, and the production efficiency is relatively low. Summary of the Invention

[0003] The purpose of this invention is to provide a loading and unloading docking device for lithium battery drying that can open or close the drying clamps while pulling them out or pushing them into the furnace, thereby reducing the number of drying clamp transfer steps and improving production efficiency.

[0004] To achieve the above objectives, the present invention provides a loading and unloading docking device for lithium battery drying, comprising a mobile device and a drying device, wherein the mobile device is located on one side of the drying device; the drying device includes a furnace body and a drying fixture movably disposed within the furnace body; the mobile device includes a frame, a translation drive mechanism, a moving platform, a push-pull positioning mechanism, and a clamping and opening mechanism, wherein the moving platform is movably disposed on the frame; the push-pull positioning mechanism and the clamping and opening mechanism are respectively disposed on the moving platform; the translation drive mechanism is disposed between the frame and the moving platform to drive the moving platform to move, such that the push-pull positioning mechanism docks with the drying fixture and drives the drying fixture to move, and such that the clamping and opening mechanism docks with the drying fixture and drives the drying fixture to clamp or open the lithium battery.

[0005] Compared with existing technologies, this invention provides a mobile platform on the mobile device, and a push-pull positioning mechanism and a clamping / opening mechanism on the mobile platform. By using a translational drive mechanism to move the mobile platform, the push-pull positioning mechanism can approach and align with the drying fixture, allowing the drying fixture to be transferred to the frame under the action of the push-pull positioning mechanism. Furthermore, by connecting the clamping / opening mechanism to the drying fixture when it approaches, the clamping / opening mechanism can simultaneously open the drying fixture during its transfer, eliminating the need to transfer the drying fixture to a dedicated workstation for opening, thus simplifying the process. Moreover, when the push-pull positioning mechanism moves the drying fixture out of the furnace, the clamping / opening mechanism simultaneously opens the drying fixture; when the push-pull positioning mechanism moves the drying fixture into the furnace, the clamping / opening mechanism simultaneously clamps the drying fixture, thus saving significant production time and improving production efficiency.

[0006] Preferably, the drying fixture includes a base, multiple heating plates, a lead screw, a slider, and a traction member. The heating plates are arranged in an orderly fashion and movably disposed on the base. The lead screw is rotatably disposed on the base and threadedly connected to the slider. The output end of the clamping and opening mechanism is connected to the lead screw and can drive the lead screw to rotate. The slider is connected to the foremost heating plate, and the traction member connects adjacent heating plates. By using the lead screw to drive the slider to slide, the slider can cause the arranged heating plates to move closer together, thereby automatically clamping the lithium battery. Alternatively, the traction member can cause the heating plates to move away from each other, thereby automatically opening the clamp.

[0007] Specifically, the clamping and opening mechanism includes a rotating shaft and a rotary drive mechanism. The rotary drive mechanism is mounted on the moving platform and its output end is connected to the rotating shaft. One end of the rotating shaft can be connected to the lead screw, so that the rotating shaft and the lead screw are circumferentially fixedly connected but axially separable. By connecting the rotating shaft to the lead screw, both axial connection between the rotating shaft and the lead screw can be easily achieved, and the rotating shaft can quickly drive the lead screw to rotate. Its structure is simple and the connection is convenient.

[0008] Specifically, the rotary drive mechanism includes a first motor, a driving synchronous pulley, a driven synchronous pulley, and a synchronous belt. The output end of the first motor is connected to the driving synchronous pulley, the driven synchronous pulley is connected to the rotating shaft, and the synchronous belt surrounds the driving synchronous pulley and the driven synchronous pulley.

[0009] Preferably, the drying fixture has a locking block on the side near the push-pull positioning mechanism, and the locking block has a locking groove for engaging the output end of the push-pull positioning mechanism. By providing a locking block and a locking groove, the output end of the push-pull positioning mechanism can be inserted, thereby enabling the push-pull positioning mechanism to quickly align and connect with the drying fixture, improving the ease of connection.

[0010] Specifically, a limiting rod is pivotally connected within the engaging groove. Under gravity, the limiting rod engages with the furnace body, locking the drying fixture relative to the furnace body. When pushed off by the output end of the push-pull positioning mechanism, the rod rotates and disengages from the furnace body, releasing the drying fixture from the furnace body. By providing the limiting rod and pivotally connecting it within the engaging groove, the output end of the push-pull positioning mechanism can simultaneously drive the limiting rod to rotate when inserted into the engaging groove. This rotation allows the drying fixture to be unlocked from the furnace body while simultaneously connecting to the push-pull positioning mechanism, simplifying the process and improving production efficiency.

[0011] Specifically, the push-pull positioning mechanism includes a fastening block and a transverse drive mechanism. The output end of the transverse drive mechanism is connected to the fastening block, and the fastening block can extend into or retract from the locking groove.

[0012] Specifically, a roller is pivotally connected to the fastening block, with opposite sides of the roller extending out of the fastening block to contact the two opposite inner walls of the engaging groove when the fastening block extends out of the engaging groove. This allows the fastening block to fit more tightly with the engaging groove when inserted, preventing gaps between them and thus avoiding positional errors between the drying fixture and the push-pull positioning mechanism, thereby achieving accurate positioning.

[0013] Specifically, the drying fixture has an oven door on the side near the push-pull positioning mechanism, and the oven door moves with the drying fixture. By making the oven door and the drying fixture an integral structure, the oven door can be opened synchronously the moment the drying fixture leaves the oven body, or closed synchronously at the final stage of entering the oven body. Therefore, there is no need to drive the oven door to open or close through any mechanism, which effectively simplifies the process and makes control more convenient.

[0014] Preferably, the translation drive mechanism includes a drive motor, a drive gear, and a rack. The drive motor is mounted on the moving platform, the drive gear is connected to the output end of the drive motor, and the rack is mounted on the frame, meshing with the drive gear. By engaging the drive gear and the rack, the drive motor drives the drive gear to rotate, thereby allowing the drive rack to move along its direction, thus achieving the purpose of driving the moving platform. This drive method has a simple structure, is easy to control, and has a fast response speed, resulting in rapid action and precise positioning of the moving platform. Attached Figure Description

[0026] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0027] like Figures 1 to 3 As shown, the loading and unloading docking device 100 for lithium battery drying of the present invention includes a mobile device 1 and a drying device 2. The mobile device 1 is located on one side of the drying device 2. The drying devices 2 are arranged in an array, and the mobile device 1 is movably arranged along the arrangement direction of the drying devices 2, so that one mobile device 1 can dock with multiple drying devices 2. In addition, the drying devices 2 can be arranged in two rows, and the mobile device 1 is arranged between the two rows of drying devices 2. Specifically, the drying device 2 includes a furnace body 21 and a drying clamp 22 movably arranged in the furnace body 21. The moving direction of the drying clamp 22 is perpendicular to the moving direction of the mobile device 1. The furnace body 21 has multiple layers, and each layer has multiple rows of cavities 211. The drying clamp 22 is arranged one-to-one in the cavity 211. The mobile device 1 includes a frame 11, a translation drive mechanism 12, a moving platform 13, a push-pull positioning mechanism 14, and a clamping and opening mechanism 15. The frame 11 is movably arranged along the arrangement direction of the drying devices 2. The mobile platform 13 is movably mounted on the frame 11 and moves in the same direction as the drying equipment 2. The push-pull positioning mechanism 14 and the clamping / opening mechanism 15 are respectively mounted on the mobile platform 13. Specifically, mounting seats 131 are fixedly provided on both sides of the mobile platform 13. The push-pull positioning mechanism 14 and the clamping / opening mechanism 15 are arranged vertically and supported on the two mounting seats 131. More specifically, the push-pull positioning mechanisms 14 are symmetrically arranged, meaning that each mounting seat 131 has one push-pull positioning mechanism 14, allowing both push-pull positioning mechanisms 14 to simultaneously push and pull to position one drying clamp 22. This ensures that the drying clamp 22 has two force points during movement, achieving force balance and more stable movement. The translation drive mechanism 12 is disposed between the frame 11 and the mobile platform 13 to drive the mobile platform 13 to move, so that the push-pull positioning mechanism 14 docks with the drying fixture 22 and drives the drying fixture 22 to move, and so that the clamping and opening mechanism 15 docks with the drying fixture 22 and drives the drying fixture 22 to clamp or open the lithium battery.

[0028] Please see Figure 7 The drying fixture 22 includes a base 221, multiple heating plates 222, a lead screw 223, a slider 224, a traction member 225, and a guide rod 226. The guide rod 226 is disposed on the base 221. The heating plates 222 are arranged in a movably disposed on the base 221 and slidably fitted onto the guide rod 226. Their arrangement direction and movement direction are the same as the movement direction of the drying fixture 22. The lead screw 223 is rotatably disposed on the base 221 and threadedly connected to the slider 224. The lead screw 223 is disposed on opposite sides of the base 221, and the central axis of the lead screw 223 is in the same direction as the movement direction of the heating plates 222. One end of the lead screw 223 protrudes from the front side of the base 221 and is exposed outside the front side of the drying fixture 22 to facilitate docking with the clamping and opening mechanism 15. The output end of the clamping and opening mechanism 15 is detachably connected to the lead screw 223 and can drive the lead screw 223 to rotate. When the output end of the clamping and opening mechanism 15 approaches the end of the lead screw 223, the two are coaxially engaged to fix it in the circumferential direction, thereby achieving torque transmission. The slider 224 is connected to the heating plate 222 located in the foremost direction, so that when the slider 224 moves backward, it pushes the heating plate 222 in the foremost direction, causing it to move closer to the heating plate 222 in the rear, thereby gathering and pressing all the heating plates 222 together. The traction member 225 is connected between two adjacent heating plates 222, so that when the slider 224 moves forward, the traction member 225 pulls each heating plate 222 to spread out at the maximum spacing. By using the lead screw 223 to drive the slider 224 to slide, the slider 224 can cause the arranged heating plates 222 to move closer to each other, thereby achieving automatic clamping of the lithium battery. Alternatively, the heating plates 222 can be moved away from each other by the traction member 225, thereby achieving automatic clamping.

[0029] Please see again Figure 3 , Figure 5 , Figure 6 and Figure 9The clamping and opening mechanism 15 includes a rotating shaft 151 and a rotary drive mechanism 152. The rotating shaft 151 is pivotally connected to the mounting base 131, and its central axis direction is in the same direction as the movement direction of the moving platform 13. The rotating shaft 151 is coaxially arranged with the lead screw 223. There are two rotating shafts 151, each corresponding to one of the lead screws 223. One end of the rotating shaft 151 can be connected to the lead screw 223, so that the rotating shaft 151 and the lead screw 223 are circumferentially fixedly connected but axially separable. The end face of the rotating shaft 151 near the lead screw 223 has a radially provided engagement recess 151a, and the end of the lead screw 223 has an engagement protrusion 223a. When the rotating shaft 151 is connected to the lead screw 223, the engagement recess 151a and the engagement protrusion 223a engage. At this time, the rotating shaft 151 and the lead screw 223 are circumferentially fixed, but the rotating shaft 151 is not restricted in the axial direction away from the lead screw 223. The rotary drive mechanism 152 is mounted on the moving platform 13 and its output end is connected to the rotating shaft 151. By connecting the rotating shaft 151 to the lead screw 223, it is possible to easily connect the rotating shaft 151 and the lead screw 223 axially, and the rotating shaft 151 can quickly drive the lead screw 223 to rotate. Its structure is simple and the connection is convenient. Specifically, the rotary drive mechanism 152 includes a first motor 152a, a driving synchronous pulley 152b, a driven synchronous pulley 152c, and a synchronous belt 152d. The driving synchronous pulley 152b and the driven synchronous pulley 152c are pivotally connected to the mobile platform 13. The first motor 152a is mounted on the mobile platform 13 and its output end is connected to the driving synchronous pulley 152b. The driven synchronous pulleys 152c are connected to the rotating shaft 151 one-to-one. The synchronous belt 152d surrounds the driving synchronous pulley 152b and the driven synchronous pulley 152c. Furthermore, since the drying devices 2 are respectively located on opposite sides of the mobile device 1, the clamping and opening mechanism 15 needs to be correspondingly located at both ends of the mobile platform 13. In this embodiment, the two ends of the rotating shaft 151 are extended, and the docking structure at both ends of the rotating shaft 151 is made identical. In this way, both ends of the rotating shaft 151 can be connected to the drying clamp 22 on the same side. Therefore, only one clamping and opening mechanism 15 is needed to connect the drying clamps 22 on different sides, which greatly simplifies the structure.

[0030] For example Figure 1 , Figure 10 and Figure 11As shown, the drying fixture 22 has a locking block 23 on its outer side near the push-pull positioning mechanism 14. The locking block 23 has a locking groove 231 that extends through both ends, and the extension direction of the locking groove 231 is perpendicular to the movement direction of the moving platform 13. The locking groove 231 allows the output end of the push-pull positioning mechanism 14 to be inserted from one end to achieve locking and docking. By setting the locking block 23 and the locking groove 231 on the locking block 23, the output end of the push-pull positioning mechanism 14 can be inserted, thereby enabling the push-pull positioning mechanism 14 to quickly align and connect with the drying fixture 22, improving the convenience of connection. A limit rod 24 is pivotally connected inside the locking groove 231, and a locking block 25 is set on the front side of the furnace body 21 near the edge of the furnace opening. The locking blocks 25 are symmetrically distributed on both sides of the furnace opening. When the drying clamp 22 is placed inside the furnace body 21, the free end of the limiting rod 24 rotates downward under gravity and engages with the locking block 25 of the furnace body 21, thus locking the drying clamp 22 relative to the furnace body 21 and preventing accidental detachment. When pushed against by the output end of the push-pull positioning mechanism 14, the limiting rod 24 rotates, and its free end disengages from the locking block 25 of the furnace body 21, releasing the drying clamp 22 from the furnace body 21. By setting the limiting rod 24 and pivotally connecting it to the engaging groove 231, the output end of the push-pull positioning mechanism 14 can simultaneously drive the limiting rod 24 to rotate when inserted into the engaging groove 231. This rotation of the limiting rod 24 allows the drying fixture 22 to be unlocked from the furnace body 21 while the push-pull positioning mechanism 14 is connected to the drying fixture 22, simplifying the process steps and improving production efficiency.

[0031] Please see again Figure 3 , Figure 4 , Figure 10 and Figure 11The push-pull positioning mechanism 14 includes a fastening block 141 and a transverse drive mechanism 142. The output end of the transverse drive mechanism 142 is connected to the fastening block 141, and the fastening block 141 can extend into or retract from the engaging groove 231. The transverse drive mechanism 142 includes a base plate 142a, a second motor 142b, a second lead screw 142c, a second nut 142d, and a transverse support 142e. The base plate 142a is fixed to the mounting base 131. The second motor 142b is mounted on the base plate 142a. The second lead screw 142c is pivotally connected to the base plate 142a, and its central axis is perpendicular to the moving direction of the moving platform 13. The second screw is threadedly connected to the second lead screw 142c and fixedly connected to the transverse support 142e. The transverse support 142e is slidably mounted on the base plate 142a via a track, and the fastening block 141 is fixed to the transverse support 142e. Since the drying devices 2 are respectively located on opposite sides of the mobile device 1, the push-pull positioning mechanism 14 needs to be correspondingly located at both ends of the mobile platform 13. In this embodiment, by extending both ends of the transverse support 142e and setting the same structure of the fastening block 141 at both ends of the transverse support 142e, both ends of the transverse support 142e can be connected to the drying clamp 22 on the same side. Therefore, only one push-pull positioning mechanism 14 is needed to connect the drying clamps 22 on different sides, greatly simplifying the structure. Specifically, a roller 141a is pivotally connected to the fastening block 141. The opposite sides of the roller 141a extend beyond the opposite sides of the fastening block 141, that is, the diameter of the roller 141a is greater than the width of the fastening block 141, so that when the fastening block 141 extends out of the engaging groove 231, it contacts the two opposite inner walls of the engaging groove 231. This allows the fastening block 141 to fit more tightly with the locking groove 231 when it is inserted into the locking groove 231, preventing gaps between them and causing positional errors between the drying clamp 22 and the push-pull positioning mechanism 14, thereby achieving accurate positioning.

[0032] For example Figure 9 As shown, the drying clamp 22 has a furnace door 227 on the side near the push-pull positioning mechanism 14, and the furnace door 227 moves with the drying clamp 22. The locking block 23 is located on the outside of the furnace door 227. By making the furnace door 227 and the drying clamp 22 an integral structure, the furnace door 227 can be opened synchronously at the moment the drying clamp 22 leaves the furnace body 21, or closed synchronously at the final stage of entering the furnace body 21. Therefore, there is no need to drive the furnace door 227 to open or close through any mechanism, which effectively simplifies the steps and makes control more convenient.

[0033] For example Figure 2 and Figure 5 As shown, the translation drive mechanism 12 includes a drive motor 121, a drive gear 122, and a rack 123. The drive motor 121 is mounted on the moving platform 13, the drive gear 122 is connected to the output end of the drive motor 121, and the rack 123 is mounted on the frame 11, with the drive gear 122 meshing with the rack 123. By engaging the drive gear 122 with the rack 123, the drive motor 121 drives the drive gear 122 to rotate, thereby allowing the drive rack 123 to move along the direction of the rack 123, thus achieving the purpose of driving the moving platform 13 to move. This drive method has a simple structure, is easy to control, and has a fast response speed, thus enabling the moving platform 13 to react quickly and move precisely.

[0034] Please see again Figure 1 Furthermore, the mobile device 1 of the present invention may also be equipped with a crane-mounted robotic arm 16 and a lifting mechanism (not shown in the figure). The lifting mechanism can raise or lower the mobile platform 13 so that the mobile platform 13 can be positioned on the layer where the drying fixture 22 to be docked is located. The crane-mounted robotic arm 16 has grippers that can simultaneously grip and place multiple lithium batteries onto the drying fixture 22, or simultaneously remove lithium batteries from the drying fixture 22. The crane-mounted robotic arm 16 and the lifting mechanism are not the focus of this application, and therefore will not be described in detail.

[0035] Based on the above and in conjunction with the accompanying drawings, the working principle of the lithium battery drying loading and unloading docking device of the present invention will be described in detail below:

[0036] When lithium batteries need to be placed in the drying equipment 2 for drying, firstly, the frame 11 moves to the front of the drying equipment 2 where the drying fixture 22 is located. Then, the lifting drive mechanism drives the moving platform 13 to rise to the layer where the drying fixture 22 is located. At this time, the translation drive mechanism 12 drives the moving platform 13 to extend out of the frame 11 and move closer to one side of the drying equipment 2. Then, the two push-pull positioning mechanisms 14 operate synchronously. Specifically, the second motor 142b starts and drives the second lead screw 142c, which in turn drives the transverse support 142e to move through the second nut 142d. The transverse support 142e drives the fastening block 141 to move, so that the fastening block 141 is inserted into the locking groove 231. At the same time, the fastening block 141 pushes the limiting rod 24, so that the free end of the limiting rod 24 rotates and disengages from the locking block 25. At this time, the drying fixture 22 is unlocked from the furnace body 21. Simultaneously, the engaging recess 151a at the front end of the rotating shaft 151 engages with the engaging protrusion 223a at the end of the lead screw 223. At this time, the translation drive mechanism 12 drives the moving platform 13 to move into the frame 11, and the moving platform 13 drives the drying fixture 22 to move out of the furnace body 21 and into the frame 11 through the push-pull positioning mechanism 14. During the transfer of the drying fixture 22, the first motor 152a starts, driving the active synchronous pulley 152b, which in turn drives the driven synchronous pulley 152c via the synchronous belt 152d. The driven synchronous pulley 152c drives the rotating shaft 151 to rotate, which in turn drives the lead screw 223 to rotate. The rotation of the lead screw 223 drives the slider 224 to move forward, which in turn drives the heating plate 222. At the same time, under the traction of the traction member 225, the other heating plates 222 move away from each other and maintain the maximum distance, thereby causing the drying fixture 22 to open. After the drying fixture 22 enters the frame 11, the second motor 142b starts again, causing the fastening block 141 to fully enter the locking groove 231. At this time, the roller 141a enters the locking groove 231 and abuts against both sides of the locking groove 231, so that there is no gap between the drying fixture 22 and the fastening block 141, and the drying fixture 22 reaches the completed positioning state. At this time, the overhead crane robot arm 16 can grab the lithium battery and place it between the two adjacent heating plates 222 of the drying fixture 22. Finally, the translation drive mechanism 12 drives the moving platform 13 to extend out of the frame 11 again, thereby pushing the drying fixture 22 back into the furnace body 21. At the same time, the first motor 152a starts and rotates in the opposite direction, driving the heating plates 222 to clamp together, thereby clamping and pressurizing the lithium battery.Once the drying fixture 22 is fully inserted into the furnace body 21, the second motor 142b starts and rotates in the opposite direction, driving the locking block 141 to disengage from the locking groove 231. At this time, the free end of the limiting rod 24 falls under the action of gravity and locks onto the locking block 25, thus locking the drying fixture 22 relative to the furnace body 21. In this way, the furnace body 21 can heat and dry the lithium battery inside the drying fixture 22. When it is necessary to load or unload the drying device 2 at the other end of the mobile device 1, it is only necessary to move the mobile platform 13 to the side closer to the drying device 2. The driving action is similar to that described above and will not be repeated.

[0037] Compared with the prior art, the present invention provides a mobile platform 13 on the mobile device 1, and a push-pull positioning mechanism 14 and a clamping and opening mechanism 15 on the mobile platform 13. By using a translation drive mechanism 12 to move the mobile platform 13, the push-pull positioning mechanism 14 can approach and align with the drying fixture 22, thereby allowing the drying fixture 22 to be transferred to the frame 11 under the drive of the push-pull positioning mechanism 14. Furthermore, by using the clamping and opening mechanism 15 to connect with the drying fixture 22 when it approaches, the clamping and opening mechanism 15 can simultaneously open the drying fixture 22 during the transfer process. Therefore, it is not necessary to transfer the drying fixture 22 to a dedicated workstation for opening, simplifying the process steps. Moreover, when the push-pull positioning mechanism 14 moves the drying fixture 22 out of the furnace body 21, the clamping and opening mechanism 15 simultaneously opens the drying fixture 22; when the push-pull positioning mechanism 14 moves the drying fixture 22 into the furnace body 21, the clamping and opening mechanism 15 simultaneously clamps the drying fixture 22. Therefore, a significant amount of production time can be saved, thereby improving production efficiency.

[0038] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention shall still fall within the scope of the present invention.
