Detailed Implementation

[0034] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the embodiments of this application. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such uses of the terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0036] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0037] Example: Figures 1-17 As shown, a tray immersion disinfection device includes a tray conveying mechanism 100, a tray disinfection mechanism 200, a tray retrieval mechanism 300, and a tray receiving mechanism 400. The tray disinfection mechanism 200 includes a liquid storage tank 210 and a chain conveying mechanism 220 installed on the liquid storage tank 210. The liquid storage tank 210 is used to store disinfectant. A clamping mechanism 240 is fixedly provided on the chain conveying mechanism 220. The tray conveying mechanism 100 is used to convey a tray 140 to the tray disinfection mechanism 200. The clamping mechanism 240 is used to clamp the tray 140, and the tray 140 is in a vertical state. The chain conveying mechanism 220 is used to convey the tray 140 to the liquid storage tank 210 for immersion, and then to the unloading position. The tray retrieval mechanism 300 removes the tray 140 from the unloading position and places it on the tray receiving mechanism 400. The tray receiving mechanism 400 is used to convey the tray 140 to the next process.

[0038] like Figure 1 and Figure 6As shown, the pallet picking mechanism 300, pallet receiving mechanism 400, pallet disinfection mechanism 200, and pallet conveying mechanism 100 are arranged in sequence. When the pallet conveying mechanism 100 conveys the pallet 140 to the loading position, the clamping mechanism 240 at the loading position clamps the pallet 140. Then, the chain conveying mechanism 220 carries the pallet 140 clamped by the clamping mechanism 240 through the liquid storage tank 210. The pallet 140 is immersed in the disinfectant in the liquid storage tank 210. After immersion, the chain conveying mechanism 220 continues to convey the immersed pallet 140 to the unloading position. The pallet picking mechanism 300 extends and clamps the pallet 140, then places the pallet 140 on the receiving mechanism 400. Finally, the receiving mechanism 400 conveys the pallet 140 to the next process, completing the entire disinfection process of the pallet 140. This application utilizes the cooperation between the pallet conveying mechanism 100, the pallet disinfection mechanism 200, the pallet retrieval mechanism 300, and the pallet receiving mechanism 400 to automatically complete the entire process of transporting, disinfecting, and recycling the pallet 140, thereby improving work efficiency, reducing the labor intensity of workers, and having a simple structure, small footprint, and strong practicality.

[0039] like Figures 7-8 As shown, the pallet conveying mechanism 100 includes a conveyor frame 110, a conveyor belt 120 mounted on the conveyor frame 110, and a first support 130. The conveyor belt 120 is driven by a drive motor (not shown in the figure). The conveyor frame 110 and the conveyor belt 120 are conventional conveyor belt mechanisms, which will not be described in detail here. The pallet 140 is placed vertically on the conveyor belt 120, and the first support 130 is used to support the pallet 140. That is, the first support 130 is used to keep the pallet 140 in a vertical state.

[0040] like Figures 8-9 As shown, the first support 130 includes a pole group, a clamping block 132, and a stop bar group. Several pairs of pole groups and several pairs of stop bar groups are fixedly provided on the conveyor frame 110. Each pair of pole groups includes two poles 131. The two poles 131 in each pair of pole groups are located on both sides of the conveyor frame 110. Each pair of stop bar groups includes two parallel stop bars 133. The stop bars 133 are fixedly installed on the poles 131 by the clamping block 132.

[0041] In one possible implementation, the first end of the clamping block 132 is screwed to the upright 131, and the second end of the clamping block 132 clamps the stop bar 133. The tray 140 is vertically positioned between the stop bars 133. The first support 130 is provided with two pairs of upright bar assemblies, such as... Figure 8As shown, two pairs of upright posts are fixed to the inlet and outlet ends of the first support 130, respectively. Upright posts 131 are vertically mounted on the conveyor frame 110. Stop bars 133 are arranged along the conveying direction of the conveyor belt 120. Both ends of the stop bars 133 are fixed to the upright posts 131 by clamping blocks 132. The first end of the clamping block 132 is screwed onto the upright post 131, allowing adjustment of the position of the clamping block 132 relative to the upright post 131, thereby adjusting the distance between the two stop bars 133 to accommodate the conveying needs of pallets 140 of different widths. The stop bars 133 are clamped to the second end of the clamping block 132, which is similar to a commonly used open clamp for easy fixation of the stop bars 133. In this embodiment, the upright posts are provided with three pairs of stop bar groups, each pair at a different height. Optionally, the distance between the two stops 133 in each pair of stops is equal to the thickness of the tray 140, so that the two stops 133 can clamp the tray 140 and ensure that the tray 140 will not tip over. Of course, the distance between the two stops 133 can also be slightly greater than or slightly less than the thickness of the tray 140.

[0042] like Figure 1 , Figures 10-11 As shown, the chain conveying mechanism 220 is mounted on the liquid storage tank 210 via a second bracket 230. A protective cover 250 is fixedly installed on the liquid storage tank 210, and the chain conveying mechanism 220 is located inside the protective cover 250. Optionally, the chain conveying mechanism 220 includes a chain support frame, a chain, and a motor assembly. The motor assembly drives the chain to circulate within the track of the chain support frame. A clamping mechanism 240 is fixedly installed on the chain; therefore, the chain movement can drive the clamping mechanism 240 to move synchronously. The protective cover 250 is used to protect the chain conveying mechanism 220 and the disinfectant in the liquid storage tank 210 from contamination.

[0043] like Figures 11-12As shown, the clamping mechanism 240 includes two clamping plates 241 and a spring 242 connected to the two clamping plates 241. The clamping plates 241 are mounted on the chain conveying mechanism 220, and one end of the two clamping plates 241 is hinged. In one possible embodiment, one clamping plate 241 is fixedly mounted on the chain conveying mechanism 220, the first ends of the two clamping plates 241 are hinged together, and the second ends of the two clamping plates 241 are used to clamp the pallet 140. The two clamping plates 241 are connected by the spring 242. When the spring 242 is in its natural state, the second ends of the two clamping plates 241 are open, and the distance between the two clamping plates 241 is less than the thickness of the pallet 140. When the empty clamping mechanism 240 runs to the loading position, the pallet 140 is squeezed into the two clamping plates 241 under the action of the pallet conveying mechanism 100 and is clamped by the two clamping plates 241. When the clamping mechanism 240 clamps the tray 140, the tray 140 is in a vertical position, that is, the tray 140 is immersed in the liquid storage tank 210 in a vertical position. Therefore, the width of the liquid storage tank 210 is greatly reduced, thereby reducing the space occupied by the entire disinfection device.

[0044] To accommodate the loading, immersion, and unloading actions of the pallet 140, the tracks of the chain support frame are not at the same height. The height of the chain support frame track corresponding to the point where the pallet 140 is immersed in the liquid storage tank 210 is lower than that of other parts of the track.

[0045] like Figures 13-15 As shown, the tray-retrieving mechanism 300 includes a third support 310, a linear module 320, and a gripper cylinder 340. The linear module 320 is horizontally mounted on the third support 310, and the gripper cylinder 340 is connected to the linear module 320. The linear module 320 can drive the gripper cylinder 340 to perform linear motion. The gripper cylinder 340 is provided with two grippers 341, and the gripper cylinder 340 can drive the two grippers 341 to clamp or release the tray 140.

[0046] The tray-retrieving mechanism 300 further includes a rotary cylinder 330, which is mounted on the linear module 320. The linear module 320 can drive the rotary cylinder 330 to perform linear motion. The gripper cylinder 340 is mounted on the rotary cylinder 330, and the rotary cylinder 330 can drive the gripper cylinder 340 to rotate. In the tray-retrieving mechanism 300, the linear module 320 is mounted on the third support 310, the rotary cylinder 330 is mounted on the linear module 320, and the gripper cylinder 340 is mounted on the rotary cylinder 330. When the tray 140 moves to the unloading position, the linear module 320 drives the gripper cylinder 340 to extend. The gripper cylinder 340 uses the gripper 341 to clamp the tray 140, and then retracts so that the tray 140 is directly above the receiving mechanism 400. The rotary cylinder 330 then drives the tray 140 to rotate. After the tray 140 is in a horizontal state, the gripper cylinder 340 releases the tray 140, so that the tray 140 falls onto the receiving mechanism 400.

[0047] like Figures 16-17 As shown, the receiving mechanism 400 includes a fourth support 410, a lifting mechanism 420, and a conveyor 430. The lifting mechanism 420 is fixedly installed on the fourth support 410, and the conveyor 430 is movably installed on the fourth support 410. The lifting mechanism 420 can drive the conveyor 430 to perform lifting and lowering movements, and the conveyor 430 can drive the pallet 140 to perform horizontal movements.

[0048] The lifting mechanism 420 includes a lifting cylinder, a linear motor, or a lead screw assembly. The conveyor 430 includes a conveyor belt mechanism. The conveyor 430 is slidably mounted on the fourth bracket 410 via a slide plate 440. The lifting mechanism 420 is used to lift the conveyor 430 to a preset position so that the pallet-taking mechanism 300 can place the pallet 140. The conveyor 430 is used to transport the pallet to the next process.

[0049] The operation process of this application includes the following steps:

[0050] Step 1: The pallet conveying mechanism 100 conveys the pallet 140 to be disinfected to one end of the pallet disinfection mechanism 200. At this time, the empty clamping mechanism 240 is located at the loading position of the chain conveying mechanism 220.

[0051] Step 2: Under the action of the pallet conveying mechanism 100, the pallet 140 is squeezed between the clamping plates 241 of the clamping mechanism 240 and is clamped by the clamping plates 241.

[0052] Step 3: The chain conveyor mechanism 220 conveys the tray 140 into the liquid storage tank 210, and the tray 140 is vertically immersed in the disinfectant in the liquid storage tank 210;

[0053] Step 4: The chain conveyor mechanism 220 transports the sterilized pallet 140 to the unloading position;

[0054] Step 5: The linear module 320 drives the gripper cylinder 340 to extend, and the gripper cylinder 340 uses the gripper 341 to clamp the tray 140, and then retracts so that the tray 140 is directly above the receiving mechanism 400. The rotary cylinder 330 then drives the tray 140 to rotate so that the tray 140 is in a horizontal state.

[0055] Step 6: The lifting mechanism 420 lifts the conveyor 430 to the preset position, the gripper cylinder 340 releases the pallet 140, so that the pallet 140 falls horizontally on the receiving mechanism 400, and finally the pallet 140 enters the next process under the action of the conveyor 430.

[0056] It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the scope of protection of this patent application shall be determined by the appended claims.
