Description

Technical Field

[0001] The utility model belongs to the technical field of battery production, and more specifically relates to a material taking mechanism capable of preventing multiple sheets from being carried away. Background Art

[0002] Thin sheet processing requires the suction and movement of thin sheets, often performed by a robotic arm using a vacuum suction cup. Existing technology often involves the robot sucking up multiple sheets at once, while actual operations only require one at a time. Manual monitoring and handling are inefficient and inaccurate, failing to meet the operational requirements of automated production lines, thus impacting production efficiency and pacing.

[0003] The prior art includes a technology titled "A PTC sheet suction device for lithium battery cap assembly" with a publication (announcement) number of "CN211759603U." This technology belongs to the field of new energy and energy-saving technologies and includes a vacuum joint, an air blowing joint, a flow tube, a suction head, and a floating head. A cavity is provided in the middle of the suction head, and a first boss is provided at the upper end of the floating head. The first boss is disposed within the cavity, the height of the cavity being greater than the height of the first boss, and the first boss is movable up and down within the cavity. A set of notches is uniformly provided on the inner wall of the suction head. The present invention provides a vacuum joint and an air blowing joint on the flow tube, enabling vacuum adsorption. Simultaneously, air is blown into the flow tube through the air blowing joint, further pushing the floating head to generate a slight displacement within the suction head. This allows the PTC sheet electrostatically adsorbed on the suction head to be fixed by the floating head, allowing the PTC sheet to detach from the suction head. Furthermore, the use of vacuum gas passing through the notches facilitates enhanced adsorption capacity. However, this technology does not address the technical problems and technical solutions of the present application. Utility Model Content

[0028] The following is a detailed description of the embodiments of the present invention, such as the shapes, structures, positions and connections of the various components involved, the functions and working principles of the various components, etc., by referring to the accompanying drawings.

[0029] As attached Figure 1 -Attached Figure 5As shown, the utility model is a material-picking mechanism for preventing multiple thin slices from being picked up, including a material-picking manipulator assembly 3 and a thin slice placing platform assembly 4. The material-picking manipulator assembly 3 includes a moving part, a vacuum suction cup 3.2, and a single-probe multi-sheet sensor 3.9. The thin slice placing platform assembly 4 includes a placing part and a throwing box 4.4. The throwing box 4.4 is fixed to the throwing box bracket 4.3 of the placing part. A brush 4.5 is provided on the upper end of the throwing box bracket 4.3. The brush 4.5 is located above the throwing box 4.4. When the single-probe multi-sheet sensor 3.9 detects that the vacuum suction cup 3.2 has adsorbed multiple thin slices, the vacuum suction cup 3.2 is driven by the moving part to move to the position above the throwing box 4.4 and to the side position of the brush 4.5. The moving part drives the thin slice 2.5 to move back and forth and scrape the edge of the brush 4.5, so that the excess thin slices fall into the throwing box 4.4 until the single-probe multi-sheet sensor 3.9 detects that the vacuum suction cup 3.2 has only adsorbed one thin slice. The above structure addresses the shortcomings of the existing technology and proposes an improved technical solution. The structure is configured to include a material retrieving robot assembly 3 and a sheet placement platform assembly 4. The material retrieving robot assembly 3 includes a moving component, a vacuum suction cup 3.2, and a single-probe, multi-sheet sensor 3.9. The moving component is used to drive the vacuum suction cup 3.2 to move, enabling the grabbing, placement, and movement of the sheet 2.5. The vacuum suction cup 3.2 is used to absorb and place the sheet 2.5. The single-probe, multi-sheet sensor 3.9 is used to detect whether the sheet 2.5 is a single sheet or multiple sheets, and if multiple sheets are present, any excess sheets need to be removed. The wafer placement platform assembly 4 includes a placement component and a throwing box 4.4. The placement component is the foundation for supporting the throwing box. The throwing box 4.4 is fixed to the throwing box bracket 4.3 of the placement component. The throwing box 4.4 is used to receive the removed wafers, enabling wafer recovery and reuse. The upper end of the throwing box bracket 4.3 is provided with a brush 4.5, which is located above the throwing box 4.4. The brush is used to contact the wafers 2.5 adsorbed by the vacuum suction cup 3.2 and remove excess wafers 2.5. When the single-probe multi-sheet sensor 3.9 detects that the vacuum suction cup 3.2 has adsorbed multiple wafers, the moving component drives the vacuum suction cup 3.2 to move above the throwing box 4.4 and to the side of the brush 4.5. The moving component drives the wafers 2.5 back and forth, scraping the edge of the brush 4.5, causing the excess wafers to fall into the throwing box 4.4 until the single-probe multi-sheet sensor 3.9 detects that the vacuum suction cup 3.2 has adsorbed only one wafer 2.5. After removing the excess sheet 2.5, the moving part drives the sheet 2.5 to be placed on the sheet placement platform assembly 4 for subsequent processing. The mechanism of the utility model is applicable to the field of material collection and preparation of sheet products in the battery production process, and its application scope is not limited to the battery field, and is effectively applicable to various sheet products.The material-retrieving mechanism for preventing multiple slices from being picked up described in the utility model has a simple structure. After the slices are grabbed, the number of slices is monitored, and the extra slices can be removed to avoid the situation of placing multiple slices on the placement platform. At the same time, it ensures that the thrown slices can be repeatedly recycled, thereby improving efficiency, high reliability and easy maintenance.

[0030] The retrieving robot assembly 3 also includes a column I 3.1, a color fiber amplifier 3.3, a spring 3.4, a connecting rod 3.5, a connecting plate 3.6, a guide rail pair 3.7, and a crossbeam guide rail pair 3.8. These connecting rod 3.5, connecting plate 3.6, guide rail pair 3.7, and crossbeam guide rail pair 3.8 form the moving parts. With the above structure, the retrieving robot assembly 3 is used to drive the vacuum suction cup to move, thereby facilitating the grabbing of thin sheets from the magazine assembly 2. After grabbing multiple thin sheets, the robot assembly 3 moves to the thin sheet placement platform assembly 4 to remove excess thin sheets, and then drives the thin sheets to the thin sheet placement platform assembly 4 for placement.

[0031] The top of the upright column 13.1 is connected to the crossbeam guide pair 3.8, the slider of the crossbeam guide pair 3.8 is connected to the vertical beam guide pair 3.7, the slider of the vertical beam guide pair 3.7 is connected to the connecting plate 3.6, the lower end of the connecting plate 3.6 is connected to the connecting rod 3.5 and the spring 3.4, and the plate below the connecting rod 3.5 is provided with a vacuum suction cup 3.2, a color fiber amplifier 3.3, and a single-probe multiple-sheet sensor 3.9. In the above structure, the single-probe multiple-sheet sensor 3.9 is used to monitor the number of thin sheets adsorbed. If only one sheet is adsorbed, there is no need to remove the excess thin sheets through the thin sheet placement platform assembly 4. The color fiber amplifier 3.3 is set up so that when it detects the color of the bottom of the corresponding compartment of the material box body 2.4 or the color of the bottom adhesive paper, it determines that the material in the compartment or the compartment of this material box body 2.4 has been used up, and can automatically switch to another compartment to continue taking materials.

[0032] In the structure of the present invention, if the two single-probe multiple sensors 3.9 detect that there are still multiple sheets after the brush processing, the material-taking robot assembly 3 will shake up and down and scrape the brush 4.5, so that the excess sheets will fall into the throwing box 4.4. If there are still multiple sheets of material, the vacuum of the accordion-type vacuum suction cup 3.2 will be broken, and the sheets (materials) will be directly thrown into the throwing box 4.4, and then the material will be taken again; if there are not multiple sheets, the material will continue to be placed directly above the placement platform limit block 4.6 to facilitate subsequent processing of the sheets.

[0033] The material-removing mechanism for preventing the pick-up of multiple sheets also includes a material box assembly 2, which includes a linear guide pair 2.1, a material box bracket 2.2, a material box placement platform 2.3, and a material box body 2.4. The material box body 2.4 includes a plurality of compartments 2.6, each of which forms a thin sheet placement cavity. The material box body 2.4 is located on the material box placement platform 2.3. The material box placement platform 2.3 is connected to the slider of the linear guide pair 2.1 via the material box bracket 2.2. The material box body 2.4 achieves linear motion via the linear guide pair 2.1. With the above structure, the material box body 2.4 can adapt to multi-dimensional movement as needed to meet the actual needs of vacuum suction cup adsorption. In other words, the need for flexible position adjustment of the vacuum suction cup when grabbing thin sheets in different compartments 2.6 can be realized.

[0034] The sheet placement platform assembly 4 also includes a base 4.1, columns II 4.2, a placement platform stopper 4.6, a positioning cylinder 4.7, and an upper platform plate 4.8. The base 4.1, columns II 4.2, and a material throwing box bracket 4.3 form a placement component. The upper platform plate 4.8 is fixedly connected to the base 4.1 via multiple columns II 4.2. With the above structure, the sheet placement platform assembly 4 can not only place single sheets 2.5 to be processed, but also remove excess sheets 2.5.

[0035] The placement platform limit block 4.6 and positioning cylinder 4.7 are fixed to the upper platform plate 4.8. Limiting protrusions 4.9 are provided on either side of the placement platform limit block 4.6. The positioning cylinder 4.7 is located on the side of the placement platform limit block 4.6 where the limiting protrusions 4.9 are not provided. The positioning cylinder 4.7 is connected to the push plate 4.10. In this structure, the placement platform limit block 4.6 is used to place the sheet to be processed, and the limiting protrusions 4.9 are configured as protruding structures. The limiting protrusions 4.9 on both sides of the placement platform limit block 4.6 form an L-shaped structure, forming two directional limits. Positioning cylinders are provided in the other two positions, thereby reliably achieving accurate movement and limiting of the sheet.

[0036] The vacuum cup 3.2 is an accordion-type vacuum cup, capable of picking up a thin sheet 2.5 even at an angle to the horizontal. It also achieves linear motion on the vertical plane via the vertical and horizontal guide rails 3.7 and 3.8. The accordion-type vacuum cup 3.2, characterized by its airbag structure at its lower end, can smoothly pick up materials even at an angle to the horizontal, improving the reliability of sheet suction. The spring 3.4 acts as a buffer during the retrieving process, preventing deformation caused by direct force on the sheet 2.5 and effectively protecting it from damage or loss of quality.

[0037] The unilateral fitting clearance between the material box body 2.4 and the material box placement platform 2.3 is 0.2 to 0.5 mm. The above structure improves the relative position accuracy of the material box 2.4 by controlling the gap between the material box body 2.4 and the material box placement platform 2.3. At the same time, a chamfer with an appropriate angle and distance is set on the side position of the control material box body 2.4 and the material box placement platform 2.3 to prevent the material box 2.4 from being placed in the wrong direction, which plays a fool-proof role. If multiple material boxes 2.4 are required in the same mechanism, the chamfers can be set on different edges or chamfers of different sizes to avoid mutual placement errors. The material box body 2.4 adopts a non-hollow solid bottom to avoid deformation of the material and resulting in scrap when the suction cup presses down to take the material when the number of thin sheets 2.5 is small.

[0038] The angle between the bottom plane of the internal partition of the material box body 2.4 and the horizontal plane is 2 to 5 degrees. In the above structure, when the suction cup takes the material, even if multiple sheets 2.5 are picked up, they can fall into the partition due to the vertical downward gravity, thereby reducing the probability of picking up multiple sheets of material.

[0039] The angle between the left plane of the compartment of the material box body 2.4 and the horizontal plane is 95-105 degrees. The above structure can make the sheets 2.5 contacting the left plane of the compartment have a certain offset between the layers, which facilitates the subsequent brush 4.5 to remove excess material after absorbing multiple sheets.

[0040] The present invention also relates to a method for using a material-retrieving mechanism that prevents multiple sheets from being picked up. The steps of using the material-retrieving mechanism that prevents multiple sheets from being picked up are as follows: S1. After the vacuum suction cup 3.2 moves to the material box body 2.4 to absorb the sheet 2.5, the moving component drives the sheet 2.5 to move up to a safe position. If the single-probe multi-sheet sensor 3.9 detects that there are multiple sheets below at this time, the moving component drives the vacuum suction cup 3.2 to move to a position above the throwing box 4.4; S2. The moving component drives the vacuum suction cup 3.2 to approach the brush 4.5 above the throwing box 4.4, and the moving component drives the sheet 2.5 to move back and forth and scrapes the edge of the brush 4.5, so that excess sheets fall into the throwing box The vacuum suction cup 3.2 is moved out of the throwing box 4.4 until the single-probe multi-sheet sensor 3.9 detects that the vacuum suction cup 3.2 only absorbs one sheet; S3. The moving part drives the vacuum suction cup 3.2 to leave the throwing box 4.4, and drives the sheet 2.5 to move to the position above the placement platform limit block 4.6, releases the vacuum, and the sheet 2.5 falls on the platform limit block 4.6, and then the positioning cylinder 4.7 pushes the sheet 2.5 to the position of the fitting limit protrusion 4.10; S4. The moving part returns to the initial position and the above action is repeated again; until the sheets 2.5 in a compartment 2.6 in the material box body 2.4 are taken out, the compartment 2.6 is switched; the above action is continued to be repeated until all the sheets 2.5 in the material box body 2.4 are taken out.

[0041] The action flow of the specific embodiment of the mechanism of the present utility model is as follows: the slice 2.5 to be grasped and processed is placed in the material box body 2.4, the material box body 2.4 is placed on the material box placement platform 2.3, the mechanism moves to the material taking position through the linear guide rail pair 2.1, the accordion-type vacuum suction cup 3.2 moves to the top of the slice 2.5 in the material box body 2.4, then moves down a distance and fits the slice 2.5 to form a closed space, and then a negative pressure air source is used to form a vacuum between the accordion-type vacuum suction cup 3.2 and the slice 2.5 and maintain it, after the vertical beam guide rail pair 3.7 moves up to a safe position, if the single probe multiple sensor 3.9 detects that there are multiple slices adsorbed below, then the cross beam guide rail pair 3.8 is used to move the single probe multiple sensor 3.9 to the top of the material box body 2.4. The mechanism moves horizontally to a suitable position above the throwing box 4.4, and then moves downward to a suitable position of the brush 4.5 via the vertical beam guide pair 3.7. The thin slices 2.5 scrape back and forth against the edge of the brush 4.5, causing the excess thin slices to fall into the throwing box 4.4. The thin slices adsorbed at the top will not fall until the single probe multiple sensor 3.9 detects that there is only one thin slice. The mechanism then moves up to a suitable height via the vertical beam guide pair 3.7, and moves to a suitable position above the placement platform limit block 4.6 via the horizontal beam guide pair 3.8 and the quantity guide pair 3.7. The vacuum is released, and the thin slice 2.5 is placed down. It is then pushed to the set position by the two positioning cylinders 4.7 to achieve the limit position for subsequent processing. The mechanism then returns to its initial position and repeats the above action again until all the thin slices 2.5 in a corresponding compartment of the material box body 2.4 are removed. The compartment is switched and the above action is repeated until all the thin slices 2.5 in the entire material box body 2.4 are removed, and the material box body 2.4 is replaced. This utility model addresses the problems of prior art sheet retrieving mechanisms frequently picking up multiple sheets and other materials, requiring frequent manual intervention, impacting production line efficiency, and resulting in low recovery rates for discarded materials. By providing a retrieving mechanism that prevents the picking up of multiple sheets, the utility model effectively addresses the high abnormality rate, low production efficiency, and significant material waste that often occur in automated production lines. By incorporating an accordion-type vacuum suction cup 3.2, a color fiber amplifier 3.3, and a single-probe, multi-sheet sensor 3.9, the utility model reduces the probability of picking up multiple sheets and prevents multiple sheets from being placed on the platform limit block 4.6. This improves production efficiency and reduces costs. The utility model has the advantages of a simple structure, high reliability, and easy maintenance.

[0042] The material-picking mechanism for preventing multiple sheets from being picked up described in the present invention is provided with a material-picking manipulator assembly 3 and a sheet placement platform assembly 4 during structural setting. The material-picking manipulator assembly 3 includes a moving part, a vacuum suction cup 3.2, and a single-probe multiple-sheet sensor 3.9. The moving part is used to drive the vacuum suction cup 3.2 to move, thereby realizing the grabbing, placing down, and moving of the sheet 2.5. The vacuum suction cup 3.2 is used to adsorb and place down the sheet 2.5. The single-probe multiple-sheet sensor 3.9 is used to detect whether the sheet 2.5 is a single sheet or multiple sheets. If there are multiple sheets, the excess sheets 2.5 need to be removed. The thin film placement platform assembly 4 includes a placement component and a throwing box 4.4. The placement component is the basis for supporting the throwing box. The throwing box 4.4 is fixed to the throwing box bracket 4.3 of the placement component. The throwing box 4.4 is used to receive the removed thin films to realize the recycling of the thin films 2.5. The recycled thin films 2.5 will not be damaged and can be reused. A brush 4.5 is provided at the upper end of the throwing box bracket 4.3. The brush 4.5 is located above the throwing box 4.4. The brush 4.5 is used to contact the thin films 2.5 adsorbed by the vacuum suction cup 3.2 and apply force on the thin films. The topmost thin films will not fall off easily due to the suction force, and the excess thin films are just adhered. Therefore, a certain external force is applied by the brush 4.5 to remove the excess thin films 2.5. When the single-probe multi-sheet sensor 3.9 detects that the vacuum suction cup 3.2 has absorbed multiple thin sheets, the moving component drives the vacuum suction cup 3.2 to move to the position above the throwing box 4.4 and to the side of the brush 4.5. The moving component drives the thin sheet 2.5 to move back and forth and scrapes the edge of the brush 4.5, causing the excess thin sheets to fall into the throwing box 4.4 until the single-probe multi-sheet sensor 3.9 detects that the vacuum suction cup 3.2 has only absorbed one thin sheet 2.5. After removing the excess thin sheet 2.5, the moving component drives the thin sheet 2.5 to move to the thin sheet placement platform assembly 4 for placement, facilitating subsequent processing. The mechanism of the utility model is suitable for the field of material collection and preparation of thin sheet products in the battery production process. The scope of application is not limited to the battery field and is effectively applicable to a variety of thin sheet products.

[0043] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
