[0002] The application of CCS blister insulation cover is mainly concentrated in the field of lithium battery modules and energy storage. CCS, also known as "integrated busbar" or "wiring board integration", is a new type of connection bar used in lithium battery modules. It is an integrated component composed of multiple systems such as metal electrical connection system, signal sampling system and insulation system. CCS blister insulation cover is usually used as part of the insulation system to isolate and protect the electrical connection part in the battery module to prevent safety problems such as short circuit and electric shock.

[0003] In lithium battery modules, CCS blister insulation covers are widely used in commercial vehicles, passenger cars and other fields. They can effectively isolate the positive and negative electrodes and signal lines in the battery module to prevent short circuit accidents caused by contact with metal parts or intrusion of external objects.

[0004] The traditional production method of blister insulation cover is as follows: S1, blister process: the staff manually puts the sheet insulation cover raw material in the blister operation area, and then uses the heating device to heat the sheet insulation cover raw material, and the sheet insulation cover raw material reaches a softened state after heating; the molding device adsorbs the softened sheet insulation cover raw material, and the sheet insulation cover raw material is adsorbed on the surface of the molding device to form the required shape; then, it is hardened and shaped by cooling or natural cooling to obtain the semi-finished insulation cover; S2, punching process: the semi-finished insulation cover is manually transported to the punching device by the staff, and the punching device punches out the specified shape and internal circular hole shape to obtain the finished insulation cover; S3, appearance inspection process: the finished insulation cover is manually transported to the appearance inspection area by the staff, and the finished insulation cover is manually dusted and the appearance of the finished insulation cover is observed with the naked eye to determine whether the finished insulation cover has defects. Finally, the staff separately stores the finished insulation cover with appearance defects and the finished insulation cover without appearance defects.

[0005] However, manual dust removal and inspection of the appearance defects of the finished insulation cover products and then separate storage result in unstable quality and low production efficiency. Therefore, how to replace manual dust removal and inspection of the appearance of the finished insulation cover products with machines, automatically screen out the finished insulation cover products with appearance defects, and improve production efficiency is a technical problem that needs to be solved in the current field.

[0043] The finished product conveying assembly 22 is used to convey the finished insulation cover product 3 to the appearance inspection area;

[0044] The machine vision inspection component 21 scans from the head end to the tail end of the finished insulation cover in the appearance inspection area to obtain a finished product appearance image, then inspects the finished product appearance image to determine whether the finished insulation cover 3 has defects, and then sends the inspection result signal to the printing label component 23 through the printing signal line;

[0045] The finished product conveying assembly 22 then conveys the finished insulation cover product 3 from the appearance inspection area to the printing and dispensing area;

[0046] According to the detection result signal, when the detection result is defective, the printing label component 23 first prints a label of the defect type on the surface of the insulating cover finished product 3 in the printing and sorting area, and the printing label component 23 then sends a first sorting signal to the sorting robot 24, and the sorting robot 24 then transports the insulating cover finished product 3 from the printing and sorting area to the defective product bin 26 of the receiving component; when the detection result is not defective, the printing label component 23 does not print, and the printing label component 23 sends a second sorting signal to the sorting robot 24, and the sorting robot 24 transports the insulating cover finished product 3 from the printing and sorting area to the good product bin 25 of the receiving component.

[0047] The beneficial effects of the technical solution of the present invention are: online automatic dust removal is achieved through the dust removal machine 1, which greatly improves the dust removal efficiency and quality stability; the machine vision detection component 21 of the automatic inspection machine 2 replaces the human eye to detect the appearance of the insulating cover finished product 3, achieves consistency in detection standards, avoids the outflow of defective products, and improves detection efficiency; and prints a label of the defect type on the insulating cover finished product 3 with appearance defects through the label printing component, which helps quality inspectors to quickly confirm what kind of appearance defect it is, and then automatically screens the insulating cover finished products 3 with appearance defects through the material sorting robot 24 and stores them separately, thereby improving production efficiency.

[0048] Furthermore, the machine vision inspection component 21 includes an industrial camera 211, a substrate 212, a motor 213, a driving wheel 214, a first guide wheel 215, a second guide wheel 216, a transmission belt 217 and a detection frame 218, the industrial camera 211 is fixedly arranged on the substrate 212, the substrate 212 is horizontally slidably connected to the detection frame 218, the body of the motor 213 is fixedly arranged on the substrate 212, the output shaft of the motor 213 is fixedly connected to the center of the driving wheel 214, the first guide wheel 215 and the second guide wheel 216 are both rotatably arranged on the substrate 212, the two ends of the transmission belt 217 are respectively fixedly arranged at the entrance and exit of the detection frame 218, the transmission belt 217 is wound around the first guide wheel 215, the driving wheel 214, and the second guide wheel 216, and the industrial camera 211 is located above the appearance inspection area.

[0049] The beneficial effects of this technical solution are as follows: the finished insulation cover 3 enters and stops in the appearance inspection area, and the industrial camera 211 moves between the entrance and exit of the inspection frame 218 to scan from the head end of the finished insulation cover 3 to the tail end of the finished insulation cover 3, thereby obtaining a photographed image of the finished insulation cover 3; this solution is suitable for situations where the finished insulation cover 3 is larger in size.

[0050] Furthermore, the machine vision inspection component 21 also includes a detection probe, which is installed at the entrance of the appearance inspection area and is also connected to the finished product conveying component through a conveying signal line. The detection probe is used to detect the finished insulation cover.

[0051] The beneficial effect of this technical solution is: when there is a finished insulation cover product in the appearance inspection area, when the detection probe finds another finished insulation cover product at the entrance of the detection frame, the detection probe sends a signal to the finished product conveying component, and the finished product conveying component stops conveying. After the finished insulation cover product in the appearance inspection area is inspected, the machine vision inspection component sends a signal to the finished product conveying component, and the finished product conveying component starts conveying.

[0052] Furthermore, the printing label assembly 23 is laser marked to form graphic marks on the surface of the finished insulation cover 3;

[0053] The machine vision detection component 21 pre-saves defect type graphic data. When the machine vision detection component 21 determines that the insulation cover finished product 3 is defective, the detection result signal is a defect-free signal; when the machine vision detection component 21 determines that the insulation cover finished product 3 is defective, the detection result signal includes the corresponding defect type graphic data.

[0054] The beneficial effect of this technical solution is that the defect type label is a graphic mark, and the quality inspector can intuitively see what kind of appearance defect it is. The machine vision detection component 21 detects and analyzes the appearance defect type in the finished product appearance image, and then searches for the defect type graphic data, and sends the corresponding defect type graphic data to the printing label component 23 and the material separation robot 24.

[0055] In this embodiment, the appearance defects of the finished insulation cover 3 are mainly of two types: one is that the blister is not formed; the other is that the convex bulge is stretched. For example, when the machine vision detection component 21 detects and analyzes the appearance defect type in the finished product appearance image as the blister is not formed, the printing label component 23 uses laser marking to form the text of the blister is not formed on the surface of the finished insulation cover 3.

[0056] Furthermore, the good product bin 25 and the bad product bin 26 of the receiving assembly are respectively located on the left and right sides of the printing label assembly 23, and the material dividing robot 24 is located above the finished product conveying assembly 22. The material dividing robot 24 includes a material dividing frame 241, a left and right driving mechanism 242, a base 243, a lifting driving mechanism 244 and a suction nozzle 245. The suction nozzle 245 is connected to the base 243 through the lifting driving mechanism 244, and the base 243 is connected to the material dividing frame 241 through the left and right driving mechanism 242.

[0057] Further, the dust collector 1 includes a dust removal frame 11, a first rotary strong wind dust blowing component 12, a second rotary strong wind dust blowing component 13 and a height adjustment component 15, a clamping dust removal channel 14 is formed between the first rotary strong wind dust blowing component 12 and the second rotary strong wind dust blowing component 13, the first rotary strong wind dust blowing component 12 is connected to the dust removal frame 11 through the height adjustment component 15, the second rotary strong wind dust blowing component 13 is fixedly connected to the dust removal frame 11, and the first rotary strong wind dust blowing component 12 and the second rotary strong wind dust blowing component 13 have the same structure;

[0058] The first rotary strong wind dust blowing component 12 includes a shell 121, an ion electrostatic wind rod 122, a driving shaft 123, a driven shaft 124 and a clamping line 125. The shell 121 has an air inlet and an air outlet. The ion electrostatic wind rod 122 is fixedly arranged inside the shell 121. The driving shaft 123 and the driven shaft 124 are both rotatably arranged at the air outlet. The clamping line 125 is wound around the driving shaft 123 and the driven shaft 124, and a plurality of the clamping lines 125 are arranged at intervals along the axial direction.

[0059] The beneficial effects of this technical solution are as follows: the finished insulation cover 3 enters the clamping and dust removal channel 14, the clamping line of the first rotary strong wind dust blowing component 12 and the clamping line of the second rotary strong wind dust blowing component 13 clamp the finished insulation cover 3 up and down respectively, the driving shaft 123 moves the clamping line 125, so that the clamping line 125 moves with the finished insulation cover 3, the wind passes through the gap between the two adjacent clamping lines 125 and then blows to the finished insulation cover 3, the ion electrostatic wind rod 122 generates ions, the ions are blown to the surface of the finished insulation cover 3 with the help of the wind, the dust adheres to the ions and is blown away by the wind, and the finished insulation cover 3 moves and removes dust at the same time. The height adjustment component 15 adjusts the distance between the first rotary strong wind dust blowing component 12 and the second rotary strong wind dust blowing component 13, thereby adjusting the height of the clamping and dust removal channel 14, which helps to adapt to the finished insulation cover 3 of different heights.

[0060] The working mode of the present invention is:

[0061] The raw material of the insulation cover is heated to soften, adsorbed to form, cooled to harden, and becomes a semi-finished insulation cover in the blister process; then the semi-finished insulation cover is punched out into a specified shape and an internal circular hole shape in the punching process to become a finished insulation cover 3. The staff puts the finished insulation cover 3 into the device with dust removal and detection function of the present invention, and the finished insulation cover 3 first enters the dust removal machine 1 and then enters the automatic detection machine 2.

[0062] Dust collector 1: Mainly used to remove dirt and particles on the surface of the product.

[0063] Automatic inspection machine 2: It realizes online inspection of product appearance and defective phenomena, and prints labels for finished insulation cover products 3 with appearance defects, i.e. defective products, to mark what the defective phenomena are. Good and defective products identified by the automatic inspection machine 2 are collected separately. One side is a good product bin 25 for storing finished insulation cover products 3 without appearance defects, and the other side is a defective product bin 26 for storing finished insulation cover products 3 with appearance defects; and neat stacking is achieved at the same time.

[0064] Specifically, the automatic inspection machine 2 is mainly completed by the machine vision inspection component 21. The machine vision inspection component 21 uses machine vision to replace the human eye to detect the appearance defects and identification of various products. It mainly collects product images through devices such as industrial cameras 211, and uses image processing and analysis to detect product defects.
