Description

Technical Field

[0001] The present application relates to the technical field of battery cell production equipment, and particularly to a sheet loading mechanism and a sheet loading device. Background Art

[0002] During the processing of sheets (such as silicon wafers, battery cells), it is necessary to load the sheets through a loading device. The loading device usually includes two pick-up mechanisms arranged in parallel and a main conveyor line. The two pick-up mechanisms alternately dock with the main conveyor line to transport the sheets in the flower basket to the main conveyor line, and the main conveyor line then transports the received sheets to the next process.

[0003] The existing pick-up mechanism includes a flipping frame, a flipping driving member, a lifting driving member, and a sheet conveyor line. The flipping frame can clamp or release the flower basket. The flipping driving member drives the flipping frame to flip to a horizontal state or a vertical state. When the flipping frame is in the horizontal state, the handling mechanism moves the full flower basket onto the flipping frame or removes the empty flower basket from the flipping frame to implement the loading of the full flower basket and the unloading of the empty flower basket. When the flipping frame is in the vertical state, the lifting driving member drives the flipping frame to descend, and cooperates with the sheet conveyor line to pick up the sheets in the flower basket on the flipping frame one by one and transport them to the main conveyor line.

[0004] Obviously, the existing loading device implements loading by handling the flower basket, which requires frequent switching between the empty flower basket and the full flower basket, resulting in low loading efficiency. Moreover, it is necessary to reserve the flipping space of the flipping frame, which occupies a large space. Summary of the Utility Model

[0053] In order to make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0054] During the processing of a sheet body (such as a silicon wafer or a battery chip), it is necessary to load the sheet body through a loading device. The loading device usually includes two wafer picking mechanisms arranged in parallel and a main conveyor line. The two wafer picking mechanisms alternately dock with the main conveyor line to transport the sheet bodies in the flower basket to the main conveyor line, and the main conveyor line then transports the received sheet bodies to the next process.

[0055] The existing wafer picking mechanism includes a flipping frame, a flipping driving member, a lifting driving member, and a sheet body conveyor line. The flipping frame can clamp or release the flower basket. The flipping driving member drives the flipping frame to flip to a horizontal state or a vertical state. When the flipping frame is in the horizontal state, the handling mechanism moves the full flower basket onto the flipping frame or removes the empty flower basket from the flipping frame to perform loading of the full flower basket and unloading of the empty flower basket; when the flipping frame is in the vertical state, the lifting driving member drives the flipping frame to descend, and in cooperation with the sheet body conveyor line, the sheet bodies in the flower basket on the flipping frame are taken out one by one and transported to the main conveyor line.

[0056] Obviously, the existing loading device implements loading by handling the flower basket, which requires frequent switching between the empty flower basket and the full flower basket, resulting in low loading efficiency; moreover, it is necessary to reserve the flipping space for the flipping frame, which occupies a large space.

[0057] Therefore, in a first aspect, the present application proposes a sheet body loading mechanism. Referring to Figure 1 and Figure 2 as shown, a sheet body loading mechanism proposed in an embodiment of the present application includes a first driving component 10, a transverse moving frame 20, and at least two sets of wafer picking mechanisms 30. The at least two sets of wafer picking mechanisms 30 are arranged side by side on the transverse moving frame 20 along a first direction ( Figure 1 the X direction in

[0058] ). The driving end of the first driving component 10 is connected to the transverse moving frame 20. The first driving component 10 is configured to drive the transverse moving frame 20 to reciprocate horizontally along the first direction so that the at least two sets of wafer picking mechanisms 30 alternately dock with the main conveyor line 40; each set of wafer picking mechanisms 30 includes a wafer storage tooling 31, a lifting frame 32, a second driving component 33, and a conveying component 34. The wafer storage tooling 31 is fixed on the lifting frame 32. The wafer storage tooling 31 is provided with a plurality of wafer storage positions along the height direction. Each wafer storage position is configured to store a sheet body 50. The driving end of the second driving component 33 is connected to the lifting frame 32. The second driving component 33 is configured to drive the lifting frame 32 to lift and lower relative to the conveying component 34. A notch 35 for avoiding the conveying component 34 in the height direction is provided at the bottom end of the wafer storage tooling 31. The second driving component 33 drives the lifting frame 32 to descend so that the sheet bodies 50 in the wafer storage tooling 31 are sequentially placed on the feeding end of the conveying component 34. The conveying component 34 is configured to transport the received sheet bodies 50 to the main conveyor line 40 docked with the conveying component 34. Figure 1It is transported to the next process in the Y direction (in the figure), and the first direction is perpendicular to the second direction.

[0059] Specifically, the main conveyor line 40 is a narrow belt conveyor line, including two narrow belts that are parallel and spaced apart and extend in the second direction, and the sheet body 50 is carried and conveyed by the two narrow belts.

[0060] Specifically, the first driving assembly 10 adopts a first linear module arranged in the first direction, and the second driving assembly 33 adopts a second linear module arranged in the vertical direction. The fixed end of the second linear module is vertically and fixedly installed on the traversing frame 20.

[0061] For each sheet picking mechanism 30 of the sheet loading mechanism proposed in this application, a sheet storage tooling 31 for storing sheets is provided. Through the cooperation of the conveying assembly 34 and the liftable sheet storage tooling 31, the sheets in the sheet storage tooling 31 are conveyed onto the main conveyor line 40; compared with the existing sheet loading mechanism that uses a handling basket and a flipping method to implement the loading method of switching between an empty basket and a full basket, the overall structure of the loading mechanism and the loading operation process are greatly simplified, and the loading efficiency is improved; the risk of the external handling mechanism hitting the basket is also avoided, and the safety and reliability are high; moreover, since there is no need to perform a flipping action, the overall structure is compact and the occupied space is small; at the same time, through the cooperation of the first driving assembly 10, the traversing frame 20 and at least two sets of sheet picking mechanisms 30, continuous feeding to the main conveyor line 40 can be achieved.

[0062] Please refer to Figure 2 and Figure 3 As shown, as an implementation manner, the sheet storage tooling 31 includes a bottom plate 310, a top plate 311 and two connecting parts 312. The top plate 311 is fixedly arranged above the bottom plate 310 through the two connecting parts 312. The bottom plate 310, the top plate 311 and the two connecting parts 312 enclose a sheet storage space 313 extending in the height direction. A plurality of bearing grooves are arranged at intervals along the height direction on the inner sides of the two connecting parts 312, and the bearing grooves at the same height on the two connecting parts 312 form a sheet storage position.

[0063] Through the cooperation of the bottom plate 310, the top plate 311 and the two connecting parts 312, a sheet storage tooling 31 with a simple structure and low cost is provided.

[0064] As an implementation manner, the bottom plate 310 is installed on the lifting frame 32, and a notch 35 is opened on the bottom plate 310.

[0065] By installing the bottom plate 310 on the lifting frame 32 and opening a notch 35 on the bottom plate 310, it is realized to avoid the conveying assembly 34 during the lifting process of the sheet storage tooling 31, and when the sheet storage tooling 31 descends, the sheets 50 in the sheet storage tooling 31 can be sequentially placed on the feeding end of the conveying assembly 34.

[0066] As an implementation manner, the inner side of each connecting portion 312 includes at least two columns of supporting teeth 3120. Each column of supporting teeth 3120 includes a plurality of supporting teeth 3120 arranged at intervals in the height direction. A bearing groove is formed between adjacent supporting teeth 3120. The sheet body 50 is configured to be placed on the supporting teeth 3120 at the same height.

[0067] Specifically, each connecting portion 312 includes two support rods 3121 arranged at intervals in the second direction. The inner side of each connecting rod 3121 includes a column of supporting teeth 3120.

[0068] By arranging at least two columns of supporting teeth 3120 on the inner side of each connecting portion 312, and through the cooperation of the supporting teeth 3120 on the inner sides of the two connecting portions 312, a plurality of sheet storage positions are formed in the sheet storage tooling 31, further simplifying the overall structure and reducing the cost.

[0069] As an implementation manner, each connecting portion 312 further includes a side plate 3122. The side plate 3122 is located outside at least two columns of supporting teeth 3120 on the same side. The upper end of the side plate 3122 is fixedly installed on the top plate 311, and the lower end of the side plate 3122 is fixedly installed on the bottom plate 310.

[0070] By arranging the side plate 3122, protection is implemented on two opposite sides of the sheet storage tooling 31, and at the same time, the overall strength and connection reliability of the sheet storage tooling 31 can be improved.

[0071] Please refer to Figure 2 As shown, as an implementation manner, the conveying assembly 34 includes a first conveying line 340 and a second conveying line 341. The feeding end of the first conveying line 340 is located directly below the sheet storage tooling 31. The first conveying line 340 is configured to carry and convey the sheet body 50 in the second direction. The feeding end of the second conveying line 341 is docked with the discharging end of the first conveying line 340. The discharging end of the second conveying line 341 is docked with the feeding end of the main conveying line 40. The second conveying line 341 is configured to receive the sheet body 50 conveyed by the first conveying line 340 and convey the received sheet body 50 to the main conveying line 50 in the second direction.

[0072] Specifically, both the first conveying line 340 and the second conveying line 341 adopt narrow belt conveying lines. The narrow belt conveying line includes two narrow belts that are parallel, spaced apart, and extend in the second direction. The two narrow belts carry and convey the sheet body 50.

[0073] Specifically, the first conveyor line 340 and the second conveyor line 341 can be provided with adsorption components as needed. The adsorption components are arranged on the conveying paths of the first conveyor line 340 and / or the second conveyor line 341. The adsorption surface of the adsorption components is lower than the conveying surface of the first conveyor line 340 and / or the second conveyor line 341. The adsorption components are configured to adsorb the sheet body 50 on the first conveyor line 340 and / or the second conveyor line 341 downward, so as to increase the friction force between the sheet body 50 and the narrow belt of the first conveyor line 340 and / or the second conveyor line 341, and avoid the slipping of the sheet body 50.

[0074] Through the cooperation of the first conveyor line 340 and the second conveyor line 341, the sheet body 50 in the receiving and storing tooling 31 is received and automatically conveyed to the main conveyor line 40; at the same time, the first conveyor line 340 and the second conveyor line 341 can be controlled separately, which is convenient for controlling the conveying speed of the conveying component 34 and is beneficial to improving the feeding efficiency.
