Description

Technical Field

[0001] The present invention relates to the field of automated high-speed assembly, and in particular to a thin-sheet high-speed assembly zero-overlap jig module and a use method thereof. Background Art

[0002] In the technical field of assembling anti-stacking, after searching, there are only 14 related technologies. The technical research on anti-stacking in this field is still relatively superficial and cannot meet the needs of new technologies, new production capacities and new requirements.

[0003] CN220182048U discloses an anti-stacking transfer table, which belongs to the field of automated assembly equipment. The anti-stacking transfer table includes: a transfer fixture, including a fixture body and a storage groove formed by an inward depression from the upper end surface of the fixture body, and the storage groove is used to store parts; a linear module connected to the transfer fixture, the linear module includes a feeding end and a unloading end, and the linear module is suitable for driving the transfer fixture to and from the feeding end and the unloading end; a scraping mechanism is located between the feeding end and the unloading end; a waste box is arranged on the transfer fixture; wherein the scraping mechanism is suitable for scraping the stacked parts into the waste box when the transfer fixture moves from the feeding end to the unloading end. By setting the scraping mechanism and the waste box, the stacking of parts on the transfer fixture can be avoided, thereby improving the accuracy and yield rate of assembly. At the same time, the arrangement of the linear module and the scraping mechanism on the mounting frame facilitates the installation and maintenance of the equipment. However, the technical limit of this utility model can only meet the requirement of a fault tolerance rate below one ten-thousandth, and cannot be applied to the scenario requirements of high-speed automated assembly.

[0004] CN216271507U proposes an automatic anti-stacking device, which installs multiple anti-stacking devices on both sides of the assembly line. The staff can place the processed products on the upper turntable of the anti-stacking device and pass the products to the next process through the upper turntable; if the staff of the next process finds that there are unprocessed products in the previous process, they can place the unprocessed products on the lower turntable and turn them back to the staff of the previous process for processing; thereby avoiding the situation that the products are easily bumped, hit, scratched or even damaged during the processing operation, so that the factory assembly line can produce quickly, orderly and efficiently. This utility model belongs to the field of manned assembly line operation, and cannot be applied to the field of fully automatic unmanned high-speed assembly.

[0005] CN219859375U provides a flexible circuit board anti-stacking grabbing device. By setting a positioning component and a static electricity removal component on the workbench, static electricity can be eliminated before grabbing the flexible circuit board, avoiding grabbing multiple flexible circuit boards in the flexible circuit board pile. At the same time, the device can well grab the flexible circuit board on the surface, improve production efficiency, and solve the problem that the flexible circuit boards are easily adsorbed together due to static electricity when stacked, resulting in multiple pieces being easily sucked up at one time when grabbing the circuit board on the surface, which is not conducive to subsequent processing. The utility model can only solve the problem of stacking scenes with light static electricity adsorption force, and cannot be applied to the thin sheet stacking scenes of conductors without magnetic force that cannot generate static electricity, and the use scenes are severely limited.

[0006] CN203242357U discloses a metal sheet with an anti-stacking function, wherein a convex bulge is formed on a metal sheet with a welding function, and the convex bulge is located outside the welding area of ​​the metal sheet, and will not affect the appearance requirements or welding performance of the metal sheet. At the same time, the design of the convex bulge avoids the convex bulges of two stacked metal sheets from overlapping each other, further avoiding the occurrence of lamination. In addition, the convex bulge is stamped integrally with the metal sheet, the mold structure is simple, the cost is low, the stamping method is simple, suitable for mass production, and has good promotion value. CN208998619U discloses a heat sink anti-stacking structure, which realizes the stability of the overall buckling product by setting a buckling structure on the support sheet, and at the same time, the process is simple in the production process, the stamping speed is fast, and it is not easy to overlap. The support sheet is efficient in the buckling process, and the quality of the lamination is good, which overcomes the side impact method of the slider in the production process adopted in the market to prevent lamination by material thickness. In the production process, the process is complicated, the stamping speed is slow, and the overall buckling product is unstable. In addition, the structures on the market are prone to lamination during packaging, transportation, and assembly. The production and fastening process of the support sheets is inefficient and the lamination quality is poor.

[0007] All of the above are relatively close or related technologies in this field. In summary, the industry does not have a reference method for fully automatic high-speed assembly lines to solve the problem of zero stacking and prevent bad assembly during high-speed assembly. However, in the field of high-speed automated assembly, especially when assembling high-precision security parts with explosion risks, stacking defective products are completely rejected. Thin films are prone to static adsorption or small gaps between films, and they are particularly prone to stacking due to adsorption force generated by full fit. Taking lithium battery pole piece assemblies as an example, thin pole pieces are worth less than one cent, and pole piece assemblies are worth less than ten cents. However, if stacking defects are found in the qualified product area of ​​the assembly, a fine of one thousand yuan will be imposed for each piece. If one piece is defective, it means that the assembly of tens of thousands of good products is wasted. The cost of stacking assembly is extremely high. The industry calls for reliable zero-stacking high-speed automated assembly technology. Summary of the invention

DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings: Reference Figures 1 to 5 As shown, a thin sheet high-speed assembly zero-overlap jig module includes a jig body, which includes an upper jig component 1, a lower jig 2, an automatic feeding table 3, a garbage bin 4, a sensor 5, a motion control system 6, a pneumatic device 7, and a master control host 8. The pneumatic device 7 includes a vacuum suction device 71 and a blowing nozzle 72. The vacuum suction device 71 sucks the lithium battery electrode sheet thin material from the automatic feeding table 3 and transports the lithium battery electrode sheet thin material to the assembly table for assembly. The upper jig motion control system 61 includes a lifting motion system 611, a horizontal translation motion system 612, a horizontal rotation motion system 613 and a precise positioning motion system 614.

[0026] The pneumatic control system 63 includes a vacuum suction device suction pressure controller 631 and a blowing nozzle blowing pressure controller 632 .

[0027] The blowing nozzle blowing air pressure controller 632 is provided with a first blowing air pressure and a second blowing air pressure, wherein the first blowing air pressure is used to blow away dirt on the surface of the lithium battery pole sheet thin material and to blow away the excess lithium battery pole sheet thin material with weak adsorption force between the stacked sheets; the blowing air pressure of the second blowing air pressure is greater than the first blowing air pressure and is gradually increased, and is used to further separate the stacked sheets, blow away excess stacked sheets, or blow away all the lithium battery pole sheet thin materials sucked by the vacuum suction device, and blow the lithium battery pole sheet thin materials into the garbage bin 4.

[0028] A garbage blocking plate 41 is arranged on the upper outer side of the garbage bin 4, and an air suction nozzle 42 is arranged at the bottom to improve the efficiency of recycling lithium battery pole piece thin materials in the garbage bin 4; the sensor 5 is provided with a thickness detection sensor 51 and a jig area waste detection sensor 52. The waste detection sensor is a visual camera. When it finds waste in the jig area, it starts strong blowing to blow the scattered lithium battery pole piece thin materials to the garbage bin 4; the motion control system 6 is provided with an upper jig motion control system 61, an automatic feeding control system 62, a pneumatic control system 63 and a lower jig motion control system 64; the thickness detection sensor 51 is used to measure the thickness of the lithium battery pole piece thin materials sucked by the vacuum suction device 71, and the air blowing nozzle 72 is aimed at the lithium battery pole piece thin materials sucked by the vacuum suction device 71. When the thickness detection sensor 51 measures that the thickness of the lithium battery pole piece thin materials is abnormal, the thickness detection sensor 51 detects When the thickness is greater than 1.9 times the standard thickness, an abnormal instruction is output to the main control host 8 to start the second air pressure blowing. The pulling force generated by the initial blowing of the second air pressure blowing is 0.5 times the suction force of the vacuum suction device. When the thickness detection sensor 51 detects that the thickness becomes 0.9-1.2 times the standard thickness within 0.2 seconds, the second air pressure blowing is stopped and the normal assembly procedure is carried out; when the second air pressure blowing is completed for 0.2 seconds and the thickness detection sensor 51 detects that there is no detailed change in the thickness, the blowing pressure is increased by 1-20 times within 0.1 seconds, and the suction pressure of the vacuum suction device is simultaneously continuously reduced to stop, and the previously absorbed lithium battery pole sheet thin material stack is blown to the garbage bin 4 and collected by the garbage bin 4. Specific embodiments Taking the lithium battery pole piece assembly as an example, the value of the thin pole piece is less than one cent, and the value of the pole piece assembly is less than one dime. However, if it is found that there are poor laminations in the qualified product area of ​​the assembly, a fine of one thousand yuan will be imposed for each piece. If there is one defective piece, it means that the assembly of tens of thousands of good products is wasted. There are many reasons for the lamination of thin sheets, such as the influence of the electrostatic adsorption force of non-metallic parts, the surface is too clean and smooth resulting in a large actual contact area, the gap is too small and the adsorption force is large, the liquid tension such as oil and water is too large, or the thin sheet stamping and other molding process defects are sticking, etc. The thickness detection sensor 51 detects the existence of In the case of stacking, generally, the stacking is separated by blowing with a pressure of 0.3-10 atmospheres from the blowing nozzle 72 for 0.1-3 seconds. If the stacking cannot be separated even by blowing with a pressure of 10 atmospheres from the blowing nozzle 72 for 3 seconds, the stacking is regarded as inseparable and treated as garbage. In order to improve production efficiency and reduce production costs, it is appropriate to blow with a pressure of 0.3-2 atmospheres for 0.1-0.3 seconds. When the thickness detection sensor 51 detects that the thickness of the sheet is normal, there is no need to blow to separate the stacking, and the next assembly process can be carried out directly.

[0030] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
