[0044] The present invention is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0045] Example 1

[0046] like Figure 1 As shown, this embodiment relates to an automatic picking and testing production line for thin film products, including a feeding mechanism 1, a lifting and picking mechanism 2 and a screening mechanism 3.

[0049] The feeding conveying assembly 11 and the empty jig return assembly 13 use a double-speed chain conveyor to convey the membrane stacking jig 4 .

[0050] like Figure 3 As shown, the diaphragm stacking jig 4 includes a jig carrier plate 41 and a jig body 42, the jig carrier plate 41 and the jig body 42 are positioned and fixed by pins, and a limit baffle 43 is provided on the jig body 42, the limit baffle 43 matches the shape of the contact position of the film product, and is used to limit and regulate the stacking position, direction and height of the diaphragm; the jig carrier plate 41 is a power plate, and roller rolling friction is adopted with the double-speed chain conveyor to avoid friction between the diaphragm stacking jig and the wire body, so that it can be free from the constraints of the wire body and adapt to the picking and placing of diaphragm stacks of different sizes.

[0051] like Figure 4 and Figure 5 As shown, the lifting and taking mechanism 2 includes: an ion fan 21, a suction component 22, an anti-stack component 23, a lifting component 24 and a translation component 25; relative to Figure 1 and Figure 2 For continuous feeding in the assembly line, Figure 4 The loading can be done manually or by robot.

[0052] Preferably, several suction assemblies 22 are arranged side by side in a row on the first support seat 27; the first support seat 27 is fixed on the lifting assembly 24 and moves up and down with the lifting assembly 24, the lifting assembly 24 is fixed on the second support seat 28, and the second support seat 28 is fixed on the translation assembly 25 and moves back and forth with the translation assembly.

[0053] The lifting assembly 24 includes a first synchronous belt transmission assembly, which is driven by a servo motor; the first support seat 27 is fixed to the first synchronous belt in the first synchronous belt transmission assembly through a first clamping block and moves with the first synchronous belt; the lifting assembly 24 is provided with a guide rail corresponding to the first support seat 27 to improve the stability of the lifting movement.

[0054] The translation assembly 25 includes a second synchronous belt transmission assembly, which is driven by a servo motor; the second support seat 28 is fixed to the second synchronous belt in the second synchronous belt transmission assembly through a second clamping block and moves with the second synchronous belt; the translation assembly 25 is provided with a guide rail corresponding to the second support seat 28 to improve the stability of the lifting movement.

[0055] like Figure 2 , Figure 6 and Figure 7 As shown, the anti-lamination component 23 is arranged corresponding to the suction component 22, preferably, it includes a rod 231 and a blade wheel 232 sleeved on the rod, the blade wheel includes a plurality of curved blades 232a uniformly arranged in the circumferential direction, the rod 231 can be driven by a power mechanism such as a motor to drive the blade wheel 232 to rotate; the curved blade 232a has a curved surface convex toward the suction component, and is used to squeeze the sucked film product from the side. The curved blade is a rigid component, and the surface is wrapped with a polymer plastic with certain flexibility or elasticity, such as polyurethane or reinforced nylon.

[0056] Preferably, the anti-stacking assembly 23 is arranged on the top of the transfer and lifting assembly 12.

[0057] The suction assembly comprises a vacuum generator, a vacuum filter and a vacuum suction cup, wherein the vacuum suction cup is arranged on a compressible suction cup rod, and preferably, the compression amount of the suction cup rod is 10 mm.

[0058] like Figure 1 and Figure 4 As shown, the screening mechanism 3 includes a main line body 30, and a first swing arm line body 31 is provided at the entrance of the main line body. The first swing arm line body 31 is connected to the lifting and picking mechanism 2 and the main line body 30; in the process of the suction component 22 sucking the membrane product, the first swing arm line body 31 is controlled by the PLC controller to tilt synchronously, so that the suction component 22 can place the sucked membrane product on the first swing arm line body 31 without hindrance. When the suction component 22 moves toward the main line body, the first swing arm line body 31 is straightened synchronously, so that the membrane can enter the main line body without hindrance after being straightened, which is convenient for subsequent positioning detection. A sensor 20 can be set to detect the in-place signal of the second support seat 28, and the PLC controls the components in the lifting and picking mechanism to reset in sequence and the first swing arm line body to reset according to the in-place signal.

[0059] A CCD camera 32, a second swing arm line body 34 and a defective product receiving assembly 35 are sequentially arranged along the main line body. The CCD camera 32 can be arranged on both sides of the main line body, or can be arranged in the middle position in the width direction of the main line body by using a frame; sensors are arranged at the corresponding positions of the CCD camera 32 and the second swing arm line body 34, and the sensors are used to detect whether the diaphragm product has reached the above-mentioned node position; when the diaphragm product reaches the imaging position of the CCD camera 32, the main line body stops running, the CCD camera 32 takes a picture, and then the image information at the marked position on the incoming product is recognized by the image recognition module. If a defective product is found, the information is output to the PLC controller. When the defective product reaches the node position of the second swing arm line body 34 and is detected by the sensor at the position of the second swing arm line body, the PLC controller controls the second swing arm line body 34 to tilt downward, dock with the defective product receiving assembly 35, and discharge the defective products on the main line body, and then the second swing arm line body 34 returns to the normal position.

[0060] The main line body 30, the first swing arm line body 31 and the second swing arm line body 34 all adopt hollow elastic conveyor belt components; Figure 8 As shown, the hollow elastic conveyor belt assembly is provided with a modularly assembled conveyor belt pulley 300, which is arranged on a sleeve 301, and the sleeves are screwed and fixed by a transmission screw 302. According to the width of the film product, the transmission screw is rotated, and the sleeves move closer or farther from each other, thereby adjusting the line width. At the same time, the elastic conveyor belt adopts a synchronous belt, which can ensure that the line width is consistent before and after adjustment and will not deviate. In addition, the hollow design can achieve quick wiping and cleaning without interrupting production.

[0061] The working process of this embodiment is as follows:

[0062] 1) Stack the film products on the film stacking jig to form film stacks; place the film stacks on the power plate and move them to the position of the transfer and lifting assembly along with the feeding and conveying assembly; the transfer and lifting assembly lifts quantitatively according to the height of the film stack and the thickness of the film to ensure that the material taking position of the suction assembly in the lifting and taking mechanism is constant;

[0063] 2) The suction component in the lifting and picking mechanism vacuum sucks the film product, and the lifting component is lifted. While the lifting component is lifted, the blade wheel rotates synchronously, and the ion fan blows ion air synchronously, forcing the excess film adsorbed by static electricity to detach, ensuring that each time the film is sucked, it is a single film; driven by the translation component, the film product sucked by the suction component is pulled back to the first swing arm line (at this time, the first swing arm line is tilted downward), and then the negative pressure releases the vacuum suction cup; then the components in the lifting and picking mechanism are reset in turn, and the first swing arm line is also reset to the positive position, and the suction component repeats the above operation to complete the suction of a film stack product;

[0064] 3) After all the diaphragms are sucked, the empty diaphragm stacking jig moves down with the transfer and lifting assembly to the empty jig reflux assembly position for recycling; and the single diaphragms on the main line are first moved to the CCD camera imaging position for image detection. If defective products are detected, they will be guided to the defective product receiving assembly through the second swing arm line when they reach the second swing arm line; if no defective products are detected, they will be continuously transported to the subsequent process through the second swing arm line.

[0065] The embodiment of the present invention can meet the detection requirements of thin film products of different shapes and sizes. The size and displacement of the corresponding mechanism are set according to the corresponding product, and the production flexibility is good.

[0066] It should be emphasized that the above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
