Although multi-layer sensors can improve the accuracy of detection to a certain extent, this is accompanied by a sharp increase in costs. At the same time, these systems have obvious limitations, poor detection accuracy, and often misjudge qualified products as defective products, or miss truly defective products. Moreover, they can only detect a limited number of common defects, and it is difficult to fully cover the complex and diverse cap defects.

When the pressing mud is subjected to greater pressure, the bending groove can provide it with deformation space, so that the pressing mud can better fit the surfaces of different caps;

[0025] 4. By setting the push rod and the protective rubber pad, during the process of ejecting the cap, the protective rubber pad can prevent the push rod from directly contacting the protective net and pressing mud, reducing their wear and tear, while also preventing scratches and damage to the cap, protecting equipment components and cap products, extending the service life of the equipment, and ensuring product quality.

[0038] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0039] As described in the background art, existing screening equipment also has deficiencies in the collection and processing of unqualified products.

[0040] In order to solve this technical problem, the present invention provides a lithium battery cap waste screening machine, which is used for screening caps.

[0041] Specifically, please refer to Figure 1-Figure 10 , a lithium battery cap waste screening machine, comprising a screening box 1, a screening assembly 2 is provided on the screening box 1, and the screening assembly 2 comprises a screening mechanism 20 and a pressing mechanism 21;

[0042] The screening mechanism 20 includes a transmission base 201, a metal transmission belt 202 and a screening slot 203. The transmission base 201 is installed on the screening box 1, the metal transmission belt 202 is connected to the transmission base 201, and a plurality of screening slots 203 are provided on the metal transmission belt 202.

[0043] The pressing mechanism 21 includes two pressing cylinders 210, a mounting shell 211, a supporting grid 212 and pressing mud 214. The two pressing cylinders 210 are installed on the screening box 1. The mounting shell 211 is arranged in the screening box 1 and connected to the output end of the pressing cylinder 210. The supporting grid 212 is arranged on the mounting shell 211. Two extension plates 213 are symmetrically installed on the supporting grid 212. The extension plates 213 are connected to the mounting shell 211 by screws. The pressing mud 214 is attached to the supporting grid 212.

[0044] The system starts, and the optical lens captures the cap image in real time and transmits it to the AI ​​chip. The AI ​​chip and software algorithm assist in judgment based on image analysis to improve the accuracy of preliminary screening. The lithium battery caps are placed on the metal conveyor belt 202, and then the staff starts the motor connected to the transmission base 201. The motor generates power to drive the transmission base 201, which in turn drives the metal conveyor belt 202 to operate. The lithium battery caps are placed on the metal conveyor belt 202, and the transmission base 201 drives the metal conveyor belt 202 to operate, thereby driving the caps to move. While the caps are driven to move, the screening grooves 203 on the surface of the metal conveyor belt 202 can screen caps that are smaller than normal, so that caps that obviously do not meet the specifications are preliminarily screened. When the caps that meet the specifications after the preliminary screening move to the bottom of the pressing mechanism 21, the pressing cylinder 210 is started to push the installation shell 211 and the supporting grid 212 connected thereto, and the pressing mud 214 moves downward, the pressing mud 214 is made of the same material as the flower mud, and has the characteristics of light texture, looseness and porosity. It is lighter when not under force, and is convenient for installation and position adjustment; its loose and porous structure makes it possible for the pressing mud 214 to be easily trapped in the pores of the pressing mud 214 when it contacts and presses the surface of the cap, if there are protrusions or depressions on the inner side of the cap, these irregular parts can easily fall into the pores of the pressing mud 214, causing the pressing mud 214 to be brought in or stuck. The pressing mud 214 contacts and presses the surface of the cap, if there are protrusions or depressions on the inner side of the cap, these irregular parts can cause the pressing mud 214 to be brought in or stuck. During the continuous operation of the metal conveyor belt 202, the normal cap can pass through the screening slot 203 smoothly and continue to move forward with the metal conveyor belt 202 because the pressing mud 214 does not cause obvious obstruction to it; while the defective cap cannot pass through the screening slot 203 due to the obstruction of the pressing mud 214, and is thus separated from the normal cap.

[0045] The present invention provides a lithium battery cap waste screening machine, which cooperates with each other by setting a transmission base 201, a metal transmission belt 202 and a screening slot 203. When the metal transmission belt 202 is running, normal caps can smoothly pass through the screening slot 203 and continue to move forward, and caps with obvious size defects that do not meet normal specifications are preliminarily screened, while defective caps cannot pass due to the obstruction of pressing mud 214. The pressing cylinder 210 can make the pressing mud 214 contact and press the surface of the cap. The pressing mud 214 contacts the surface of the cap and utilizes its unique characteristics. When there are protrusions or depressions on the inner side of the cap, the pressing mud 214 will be brought in or stuck, thereby detecting cap defects in a simple and intuitive way, and realizing multiple separation and screening of normal and defective caps.

[0046] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0047] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0048] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0049] Please refer to Figure 4-Figure 10 , a lithium battery cap waste screening machine, the screening mechanism 20 of which also includes two mounting plates 204, a plurality of connecting plates 205 and a blocking cloth strip 206, the two mounting plates 204 are symmetrically mounted on the screening box 1, the plurality of connecting plates 205 are in a group of two, each group of connecting plates 205 is connected to the mounting plate 204, the blocking cloth strip 206 is connected to the connecting plate 205, the two connecting plates 205 are divided into inner and outer distributions, the density of the outer connecting plates 205 is less than the density of the inner connecting plates 205, each group of connecting plates 205 is located above the metal conveyor belt 202, and the connecting plates 205 and the metal conveyor belt 202 are in a close fit; when the screening mechanism 20 is running, the metal conveyor belt 202 drives the lithium battery caps to move, and when the caps pass through the connecting plates 205 and the blocking cloth strip 206 on the mounting plate 204 When the conveyor belt 202 is at the bottom, since the connecting plate 205 is in contact with the metal conveyor belt 202 and the density of the outer connecting plate 205 is lower than that of the inner connecting plate 205, the granular impurities first contact the sparser connecting plate 205 and the blocking cloth strip 206 on the outside, and some of them will be blocked. As the conveyor belt continues to run, the remaining impurities are further intercepted when passing through the denser connecting plate 205 and the blocking cloth strip 206 on the inside. When cleaning the screening mechanism 20, the staff operates relevant cleaning tools such as brushes and moves them along the running direction of the metal conveyor belt 202. While the blocking cloth strip 206 is cleaning the impurities, since the connecting plate 205 and the blocking cloth strip 206 are in contact with the caps, the caps originally stacked together can be flattened, so that the caps are evenly distributed on the metal conveyor belt 202, preparing for the subsequent screening process.

[0050] By setting up two mounting plates 204, a plurality of connecting plates 205 and blocking cloth strips 206, and utilizing blocking cloth strips 206 of different densities, and designing that the density of the outer connecting plate 205 is smaller than that of the inner connecting plate 205, a sparse structure is used for preliminary interception to prevent a large amount of impurities from being instantly blocked, and then a dense structure is used for screening, thereby ensuring the screening effect. During the cleaning process, they can also be used to flatten the stacked caps, so that the caps are more evenly distributed, thereby providing better conditions for subsequent screening and improving the overall screening efficiency.

[0051] Please refer to Figure 3-Figure 9A lithium battery cap waste screening machine, wherein the pressing mechanism 21 further comprises a protective net 215, the protective net 215 is mounted on the mounting shell 211, the protective net 215 is located above the pressing mud 214, the aperture of the protective net 215 is smaller than the aperture of the supporting grid 212, a bending groove is provided at the center of the surface of the supporting grid 212, and the pressing mud 214 is located between the supporting grid 212 and the protective net

[0052] 215; when the pressing mud 214 contacts the lithium battery cap for pressing and screening, at this time, the protective net 215 is located above the pressing mud 214 to play a protective role. When the pressing mud 214 is squeezed upward due to the irregular part on the inner side of the cap, the protective net 215 can prevent the pressing mud 214 from excessively moving upward and detaching from the supporting grid 212. The bending groove at the center of the surface of the supporting grid 212 can provide a certain deformation space for the pressing mud 214 when it is subjected to greater pressure, so that it can better adapt to the surface conditions of different caps. The aperture of the protective net 215 is smaller than that of the supporting grid 212, which can further constrain the pressing mud 214 and make it deform within a reasonable range, thereby ensuring that the pressing and screening work is carried out stably.

[0053] By setting up a protective net 215, the protective net 215 is installed on the installation shell 211 and is above the pressing mud 214. It can effectively prevent the pressing mud 214 from moving upward and detaching from the supporting grid 212 due to excessive pressure, thereby realizing the limiting protection of the pressing mud 214, ensuring the stable operation of the pressing mechanism 21, and avoiding the interruption of the screening work due to the detachment of the pressing mud 214. When the pressing mud 214 is subjected to greater pressure, the bending groove can provide it with deformation space, so that the pressing mud 214 can better fit the surfaces of different caps.

[0054] A lithium battery cap waste screening machine is further optimized, specifically, Figure 3It is shown that an ejection mechanism 22 is provided between the screening box body 1 and the mounting shell 211, and the pressing mud 214 and the protective net 215 realize the effect of ejecting the cap through the ejection mechanism 22. The ejection mechanism 22 includes a plurality of push rods 220, an ejection plate 222 and an ejection spring 223. The plurality of push rods 220 are inserted on the mounting shell 211, and the end surface of the push rod 220 close to the protective net 215 is connected with a protective rubber pad 221. The ejection plate 222 is correspondingly installed on the plurality of push rods 220, and the ejection spring 223 is compressed and arranged on the ejection plate 222 and the mounting shell 211. The ejection mechanism 22 also includes a fixing plate 224 and an ejection rod 225. The fixing plate 224 is connected to the screening box body 1, and the ejection rod 225 is installed on the fixing plate 224 corresponding to the push rod 220; the ejection rod 225 installed on the screening box body 1 is externally The ejector rod 225 contacts and pushes the corresponding push rod 220. Since the push rod 220 is inserted into the mounting shell 211 and the ejector plate 222 is connected to the plurality of push rods 220, the push rod 220 drives the ejector plate 222 to move upward together. At this time, the ejector spring 223 is in a compressed state, providing a reverse elastic force. As the push rod 220 rises, the protective rubber pad 221 contacts the protective net 215 and the pressing mud 214, and continuously applies an upward thrust, and finally ejects the cap stuck in the pressing mud 214 or judged as unqualified from the pressing area, completing the ejection operation. When the ejector rod 225 drops back to its original position, the elastic force of the ejector spring 223 resets the push rod 220, the ejector plate 222 and other components, preparing for the next ejection operation.

[0055] By providing the push rod 220 and the protective rubber pad 221, during the process of ejecting the cap, the protective rubber pad 221 can prevent the push rod 220 from directly and rigidly contacting the protective net 215 and the pressing mud 214, thereby reducing their wear and tear. At the same time, it also prevents scratches and damages to the cap, thereby protecting equipment components and cap products, extending the service life of the equipment, and ensuring product quality.

[0056] Further, such as Figure 5 and Figure 6As shown, an electric slide rail 101 is symmetrically installed on the inner wall of the screening box 1, and a collecting concave plate 102 is installed on the electric slide rail 101 through a slider. The length and width of the collecting concave plate 102 are both greater than the length and width of the installation shell 211. A guide plate 103 is connected to the collecting concave plate 102. A guide channel 104 that fits the metal conveyor belt 202 is installed on the surface of the screening box 1. The guide channel 104 is in an inverted trapezoidal shape. A guide groove is opened on the bottom surface of the screening box 1, and a storage cover box 105 corresponding to the guide groove is provided at the bottom of the screening box 1; the electric slide rail 101 is provided with a collecting concave plate 102 through a slider. The length and width of the collecting concave plate 102 are greater than the length and width of the installation shell 211. The collecting concave plate 102 is connected with a guide plate 103. A guide channel 104 that fits the metal conveyor belt 202 is installed on the surface of the screening box 1. The guide channel 104 is in an inverted trapezoidal shape. A guide groove is opened on the bottom surface of the screening box 1. A storage cover box 105 corresponding to the guide groove is provided at the bottom of the screening box 1; When the rail 101 is powered on, the motor inside it drives the slider to move on the rail, thereby driving the collecting concave plate 102 installed on the slider to move. When the pressing mechanism 21 completes the screening of the lithium battery caps and the ejection mechanism 22 ejects the unqualified caps, the collecting concave plate 102 can move to the lower part of the ejection position under the control of the electric slide rail 101 to receive the ejected unqualified caps. Since the length and width of the collecting concave plate 102 are greater than the length and width of the mounting shell 211, it can ensure that the ejected caps are completely received to prevent the caps from falling off.

[0057] At the same time, in the process of the metal conveyor belt 202 transporting the caps, the guide channel 104 plays a guiding role. Its inverted trapezoidal design enables the caps to be centrally guided during the transmission process, avoiding the displacement of the cap position due to the shaking of the conveyor belt and the like, and ensuring that the caps accurately enter the screening area. At the same time, the normal caps screened out from the pressing area continue to move forward driven by the metal conveyor belt 202. At this time, the guide channel 104 can guide the normal caps to leave the screening area smoothly, and the guide plate 103 is connected to the collecting concave plate 102. When the unqualified caps are ejected to the collecting concave plate 102, the guide plate 103 can play a certain guiding role on the caps, so that they are arranged more neatly on the collecting concave plate 102, which is convenient for subsequent processing. The bottom surface of the screening box 1 is provided with an export slot. When the collecting concave plate 102 collects a certain number of unqualified caps, it can be moved to the top of the export slot through the electric slide rail 101, and the unqualified caps fall into the corresponding cap storage box 105 at the bottom through the export slot, thereby realizing the centralized storage and management of the unqualified caps.

[0058] By setting up the electric slide 101 and the collecting concave plate 102 and utilizing the control of the electric slide 101, the collecting concave plate 102 can be flexibly moved to a designated position to receive unqualified caps, thereby improving the accuracy and convenience of collecting unqualified caps, reducing the workload of manual collection, and also reducing the possibility of cap omission or damage caused by manual operation. At the same time, the setting of the guide channel 104 and its inverted trapezoidal shape can centrally guide the caps during the cap transmission process, so that they are conveniently stored in the cap storage box 105.
