[0041] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] This utility model provides a double-sided, multi-layer drawer mechanism that enables multi-layer gripping and carrying of workpieces, increasing the number of workpieces moved at a time. When combined with stacking equipment, this mechanism increases stacking efficiency while maintaining stable operation and a wide load range. This design is primarily applicable to lithium battery production lines, used for loading and unloading battery clamps in high-volume automated high-vacuum baking production lines, specifically for the assembly and disassembly of battery clamps. The workpieces are battery clamps. This design facilitates the extraction and insertion of battery clamps into the battery baking equipment.

[0043] This solution is not limited to use in the lithium battery production field mentioned above; it can also be applied to stacking production lines in other industries. This solution will be specifically explained using battery clamp stacking in the lithium battery production field as an example.

[0044] like Figure 1-3 The diagram shown is a schematic representation of an embodiment of the double-sided multi-layer drawer mechanism provided by this utility model.

[0045] Please refer to Figure 1-3 This embodiment enables multi-layer hooking of the battery clamp to increase the carrying capacity of the battery clamp. This embodiment includes a layer-pulling frame 110, a layer-pulling moving assembly 120, and multiple parallel layer-pulling units 130. The layer-pulling moving assembly 120 is located on the layer-pulling frame 110. Each layer-pulling unit 130 includes at least two symmetrically arranged layer-pulling claws 131. The layer-pulling claws 131 are connected to the layer-pulling moving assembly 120 via a pushing member 132. The pushing member 132 pushes the layer-pulling claws 131 to move along a first direction, causing the layer-pulling claws 131 on both sides to move closer or further apart. A layer-pulling guide groove 133 is correspondingly provided below each layer-pulling claw 131, and the layer-pulling guide groove 133 is fixedly connected to the layer-pulling frame 110.

[0046] The draw-out guide groove 133 is arranged along the second direction, and its laying area covers the front end to the rear end of the draw-out frame 110. The draw-out moving component 120 drives the draw-out hooks 131 to move along the second direction and extend to the front end or rear end of the draw-out frame 110. The pusher 132 drives the draw-out hooks 131 to move closer together to clamp the battery clamp. During the process of the draw-out moving component 120 driving the draw-out hooks 131 to move along the second direction into the draw-out frame 110, the battery clamp is inserted into the draw-out guide groove 133. The battery clamp moves along the draw-out guide groove 133 into the draw-out frame 110 under the action of the draw-out hooks 131. Conversely, the process of pushing out the battery clamp is reversed. The battery clamp can enter or exit from both sides (front end and rear end) of the draw-out frame 110.

[0047] The first direction is specifically +X or -X, and the second direction is specifically +Y or -Y. The actuating component is a cylinder.

[0048] In one embodiment, the drawing hook 131 is a double-headed hook, arranged parallel to the second direction. The drawing hook 131 has hook grooves at both ends, and its middle portion is connected to the pusher 132. The drawing guide groove 133 is a bidirectional, figure-eight shaped guide groove. This design enables the battery clamp to enter and exit the drawing frame 110 in both directions. Further, the drawing hook 131 hooks the workpiece (battery clamp) from the front or rear end of the drawing frame 110 along the drawing guide groove 133 into the drawing frame 110; the drawing hook 131 then pushes the workpiece (battery clamp) out of the drawing frame 110 from the front or rear end along the drawing guide groove 133.

[0049] In one embodiment, the layer-drawing moving assembly 120 includes a first motor 121, a first reducer 122, a rack 123, a guide rail 124, and a moving plate 125. A pusher 132 is disposed on the moving plate 125, and the moving plate 125 is slidably connected to the guide rail 124. The guide rail 124 is arranged parallel to a second direction, and its laying section covers the front end to the rear end of the layer-drawing frame 110. The rack 123 is arranged parallel to the guide rail 124. The first motor 121 is disposed on the moving plate 125 and is drivenly connected to the first reducer 122. The first reducer 122 is drivenly connected to the rack 123 through a gear (not shown).

[0050] Specifically, this embodiment uses the arrangement of two layer-pulling units 130 as an example. The two layer-pulling units 130 are arranged vertically and parallel to each other. The layer-pulling claws 131 on the same side of the two layer-pulling units 130 are disposed on the moving plate 125 in the layer-pulling assembly 120 on the same side. Correspondingly, there are two sets of layer-pulling moving assemblies 120, and the two sets of layer-pulling moving assemblies 120 respectively control the layer-pulling claws 131 on the same side to move along the second direction.

[0051] The drawer frame 110 has connecting rods 111 at both ends for connection and reinforcement. The drawer frame 110 is equipped with an electric cable chain 112, which electrically connects the drawer moving assembly 120 and the pusher 132. The electric cable chain 112 drives and controls the operation of the first motor 121 of the drawer moving assembly 120 and the pusher 132.

[0052] like Figure 4-6 As shown, this utility model also provides an embodiment of a stacking device.

[0053] Please refer to Figure 4-6 This embodiment includes the aforementioned double-sided multi-layer drawer mechanism 100, and further includes a traveling mechanism 200, a lifting mechanism 300, and a loading platform 400. The lifting mechanism 300 is located on the traveling mechanism 200, and the traveling mechanism 200 drives the lifting mechanism 300 to move along a first direction. The loading platform 400 is located on the lifting mechanism 300, and the lifting mechanism 300 drives the loading platform 400 to move along a third direction. The double-sided multi-layer drawer mechanism 100 is located on the loading platform 400. Specifically, the third direction is either +Z or -Z, and the first direction, second direction, and third direction are perpendicular to each other.

[0054] This embodiment incorporates a double-sided, multi-layer drawer mechanism 100 into the stacking equipment. While possessing the advantages of traditional stacking equipment, it also offers the ability to draw layers from both sides or multiple layers, and provides precise positioning of the fixtures. This addresses and improves the efficiency and precision required for fully automated battery baking when the fixtures and their associated equipment are combined.

[0055] In one embodiment, the walking mechanism 200 includes a main frame 210, a ground rail 220, support wheels 230, guide wheels 240, a second motor 250, and a second reducer 260.

[0056] A ground rail 220 is laid along a first direction, and a corresponding overhead rail (not shown) is installed parallel above the ground rail 220. The overhead rail and ground rail 220 guide and support the main frame 210, keeping the main frame 210 vertical. Support wheels 230 are located at the bottom of the main frame 210. A second motor 250 and a second reducer 260 are located on the main frame 210. The second motor 250 is connected to the support wheels 230 via the second reducer 260, and the support wheels 230 are in rolling connection with the ground rail 220. Guide wheels 240 are located at the top of the main frame 210 and are in rolling connection with the overhead rail.

[0057] There are two sets of support wheels 230 and two sets of guide wheels 240, arranged at four corners. The second motor 250 drives the second reducer 260, which transmits power. The support wheels 230 are used for power conversion and support, converting the rotational power into the first direction of movement of the main frame 210.

[0058] Furthermore, the port of the ground rail 220 is provided with a reflector 270 for laser positioning of the distance coordinates of the main frame moving along the first direction 210.

[0059] In one embodiment, the lifting mechanism 300 includes a third motor 310, a third reducer 320, a fixed pulley 330, a steel wire rope 340, and a guide column 350, all mounted on the main frame 210. The fixed pulley 330 supports the steel wire rope 340 and is used to support the traction of the steel wire rope 340. The third motor 310 is connected to the steel wire rope 340 via the third reducer 320. The steel wire rope 340 is connected to the loading platform 400 and is used to transmit power for lifting the loading platform 400. The guide column 350 is in rolling contact with the loading platform 400 and is used to guide and limit the movement of the loading platform 400 in a third direction.

[0060] Furthermore, the lifting mechanism 300 also includes a speed limiter 360. The speed limiter 350 is located on the main frame 210, and the steel wire rope 340 passes through the speed limiter 360. The speed limiter 360 is a safety mechanism of the lifting mechanism. If an abnormal situation occurs in the stacking equipment, causing the loading platform 400 to suddenly drop, and the lifting speed exceeds a certain value, the speed limiter 360 will be activated immediately. The speed limiter 360 will lock the speed-limiting steel wire rope 340, forcing the loading platform 400 to stop descending.

[0061] In one embodiment, the loading platform 400 is used to support and carry the double-sided multi-layer drawer mechanism 100. In this embodiment, the double-sided multi-layer drawer mechanism 100 is movably connected to the loading platform 400, allowing it to move along a second direction within the loading platform 400. This is achieved by providing a fixed plate 410, a movable base plate 420, a base plate guide rail 430, a lead screw 440, a fourth motor 450, and a fourth reducer 460 on the loading platform 400. This arrangement increases the range of movement of the double-sided multi-layer drawer mechanism 100 in the second direction, facilitating its insertion into the electric oven to retrieve the battery clamps.

[0062] There are two fixed plates 410, with their backs fixedly connected to both sides of the loading platform 400. Each fixed plate 410 is equipped with a fourth motor 450 and a fourth reducer 460. The loading platform 400 is equipped with an electric cable chain 112, which is electrically connected to the fourth motor 450. The front of each fixed plate 410 has a base plate guide rail 430 and a lead screw 440. The base plate guide rail 430 and the lead screw 440 are arranged parallel to a second direction. The fourth motor 450 is driven by the lead screw 440 through the fourth reducer 460. The back of the movable base plate 420 is slidably connected to the base plate guide rail 430 and is driven by the lead screw 440, specifically through a lead screw nut 470. The front of the movable base plate 420 is connected to a double-sided multi-layer drawer mechanism 100.

[0063] The specific working process of this stacking equipment embodiment is illustrated below:

[0064] 1. Scenario 1: The loading and unloading positions are on the same side of the floor rail of the stacking equipment.

[0065] In the application scenario of loading and unloading batteries in a battery oven, it is assumed that the stacking equipment is initially unloaded, and the first battery clamp removed from the oven is an empty one. Further, it is assumed that the loading tray position and the unloading tray removal position are on the same side of the stacking equipment's ground rail 220 (i.e., both the loading tray position and the unloading tray removal position are located at the front end or the rear end of the drawer frame 110), with the loading tray position at the head end of the ground rail 220 and the unloading tray removal position at the tail end of the ground rail 220. There are two drawer units 130.

[0066] First, the main frame 210 travels along the X direction via the traveling mechanism 200 to a certain oven coordinate position (directly below oven position 1). Then, the loading platform 400 rises and falls in the Z direction to a certain layer of the oven (oven position 1). At this time, the drawer hook 131 in the double-sided multi-layer drawer mechanism 100 pulls out the empty tray battery clamp inside the oven in the +Y direction and into the drawer unit 130 of the double-sided multi-layer drawer mechanism 100 in the loading platform 400.

[0067] Then, the main frame 210 moves, and the loading platform 400 is raised and lowered to the palletizing area. At this time, the double-sided multi-layer drawer mechanism 100 places the empty battery clamps in the -Y direction at the palletizing position 1, ready for battery loading. Then, the main frame 210 moves again, and the loading platform 400 is raised and lowered to the palletizing position 2 in the loading platform area. The double-sided multi-layer drawer mechanism pulls out the full battery clamps in the +Y direction into the drawer unit 130 of the double-sided multi-layer drawer mechanism 100 in the loading platform 400.

[0068] Next, the main frame 210 moves, and the loading platform 400 is raised and lowered to another clamp position of the oven (oven position 2). The double-sided multi-layer drawer mechanism 100 will simultaneously pull out the two full trays of batteries that have been baked in the +Y direction and pull them out into the drawer unit 130 of the double-sided multi-layer drawer mechanism 100 in the loading platform 400.

[0069] Finally, the main frame 210 moves, and the loading platform 400 is raised and lowered to the unloading and dismantling area. At this time, the multi-layer drawer mechanism 100 places the empty battery tray clamp in the dismantling position 1 in the -Y direction, ready to unload the batteries. This completes a whole set of loading and unloading functions.

[0070] 2. Scenario Two: The loading pallet assembly position and the unloading pallet disassembly position are on different sides of the floor rail of the stacking equipment.

[0071] In the battery oven loading and unloading scenario, assume that the stacking equipment is initially unloaded, and the first battery clamp removed from the oven is an empty one. Further assume that the loading tray position and the unloading tray removal position are on different sides of the stacking equipment's ground rail 220 (i.e., the loading tray position and the unloading tray removal position are located at the front and rear ends of the layer-pulling frame 110, respectively), with the loading tray position at the front end of the ground rail 220 and the unloading tray removal position at the rear end of the ground rail 220. There are two layer-pulling units 130.

[0072] First, the main frame 210 travels along the X direction via the traveling mechanism 200 to a certain oven coordinate position (directly below oven position 1). Then, the loading platform 400 rises and falls in the Z direction to a certain layer of the oven (oven position 1). At this time, the drawer hook 131 in the double-sided multi-layer drawer mechanism 100 pulls out the empty tray battery clamp inside the oven in the -Y direction and into the drawer unit 130 of the double-sided multi-layer drawer mechanism 100 in the loading platform 400.

[0073] Then, the main frame 210 moves, and the loading platform 400 is raised and lowered to the pallet loading area. At this time, the double-sided multi-layer drawer mechanism 100 places the empty battery clamps in the +Y direction at the pallet loading position 1, ready for battery loading. Then, the main frame 210 moves again, and the loading platform 400 is raised and lowered to the pallet loading position 2 in the pallet loading area. The double-sided multi-layer drawer mechanism pulls out the full battery clamps in the +Y direction into the drawer unit 130 of the double-sided multi-layer drawer mechanism 100 in the loading platform 400.

[0074] Next, the main frame 210 moves, and the loading platform 400 is raised and lowered to another clamp position of the oven (oven position 2). The double-sided multi-layer drawer mechanism 100 will simultaneously pull out the two full trays of batteries that have been baked in the -Y direction and pull them out into the drawer unit 130 of the double-sided multi-layer drawer mechanism 100 in the loading platform 400.

[0075] Finally, the main frame 210 moves, and the loading platform 400 is raised and lowered to the unloading and dismantling area. At this time, the multi-layer drawer mechanism 100 places the empty battery tray clamp in the dismantling position 1 in the +Y direction, ready to unload the batteries. This completes a whole set of loading and unloading functions.

[0076] In summary, the double-sided multi-layer drawer mechanism embodiment provided by this utility model achieves workpiece hooking through the drawer unit, moves the hooked workpiece through the drawer moving component, and enables the simultaneous hooking of multiple workpieces by setting multiple drawer units, thereby increasing the number of workpieces hooked and improving efficiency. Furthermore, the drawer moving component can move the drawer unit from the front or rear of the drawer frame, increasing flexibility and expanding the applicable scenarios.
