DETAILED DESCRIPTION

[0017] A thin film glue grabbing and conveying mechanism includes a servo linear drive 1 and a glue grabbing device 2. The glue grabbing device 2 is mounted on the servo linear drive 1 and can move along the servo linear drive 1. The glue grabbing device 2 includes a glue grabbing mechanism 9 and a glue stripping mechanism 5. The glue grabbing mechanism 9 includes a glue grabbing lifting guide cylinder 10 and a suction cup 12. The suction cup 12 is connected to the glue grabbing lifting guide cylinder 10 and can be moved up and down by the cylinder's extension and contraction. The suction cup is connected to a vacuum pump via an air pipe. The suction cup 12 is provided with a fixing needle 13, which is located in the suction cup 12. The lower end of the fixing needle 13 is a tip, which is flush with the lower edge of the suction cup 12, that is, the lower end of the fixing needle 13 and the lower end of the suction cup 12 are located on the same plane. When the suction cup 12 sucks up the film, the fixing needle 13 punctures the film a little bit, that is, the tip of the fixing needle 13 penetrates the surface of the film a little, which can play a role in fixing the film and preventing the suction cup from accidentally causing some displacement of the film when the suction cup moves and drives the film. The degumming mechanism 5 includes a degumming lifting guide cylinder 6 and a degumming device 7. The degumming device 7 is connected to the degumming lifting guide cylinder 6 and can be controlled to move up and down by the extension and contraction of the cylinder. The degumming device 7 is a pressure rod. The degumming device 7 is composed of two pressure rods, which are connected by a connecting block. The connecting block is connected to the degumming lifting guide cylinder 6. The two pressure rods are arranged on the connecting block in an oblique manner, and the distance between the two pressure rods is less than the width of the film. The method of grabbing glue is as follows: the servo linear drive machine 1 controls the glue grabbing device 2 to move to the position of the film, and the glue grabbing lifting guide cylinder 10 is extended to move the suction cup 12 downward and suck the film. At this time, the suction cup can be controlled by the vacuum pump to be in an air suction state. When sucking the film, the film will bulge toward the inside of the suction cup. At this time, the fixed needle will penetrate into the surface of the film. Since the film will not undergo a large deformation, but only slightly bulge, the fixed needle will not penetrate very deeply. In addition, compared with the prior art of using a needle for puncture transfer, the pinhole left by the fixed needle is smaller and shallower than that of the needle, and because of the fixed needle piercing the film The fixing can effectively prevent the film from being displaced and achieve precise positioning of the transmission. The glue grabbing lifting guide cylinder 10 contracts and sucks up the film, and then the glue grabbing device 2 moves to the position where the film needs to be placed. The glue grabbing lifting guide cylinder 10 extends to move the suction cup 12 downward and place the film in position. The degumming lifting guide cylinder 6 extends to move the pressure rod downward and press the film, and the suction cup is put into a blowing state through the suction cup. Then the glue grabbing lifting guide cylinder 10 drives the suction cup 12 upward, and the film falls off and is located at the position where the film needs to be placed. The degumming lifting guide cylinder 6 contracts to move the pressure rod upward, completing the transmission of the film, and repeats the transmission. The glue grabbing mechanism 9 and the degumming mechanism 5 are respectively connected to the servo linear drive machine 1 through the bracket 3. One end of the bracket 3 is fixedly connected to the servo linear drive machine 1. The glue grabbing mechanism 9 and the degumming mechanism 5 are respectively arranged on the bracket 3 and are respectively located on both sides of the bracket 3.The glue grabbing device 2 is arranged on the bracket 3 through a slider 4. The slider 4 can move along the bracket 3. The slider 4 includes a slider I and a slider II. The slider I and the slider II are connected by a connecting plate. The slider 4 is sleeved on the bracket and clamped on the bracket by bolts. That is, bolt holes are respectively provided on the slider I and the slider II, and the slider I and the slider II are clamped by bolts and the slider 4 is clamped on the bracket 3; or the slider 4 is arranged on the bracket 3 by bolts, and threaded holes are respectively provided on the bracket 3 and the connecting plate, and the connecting plate is fixed to the bracket 3 by bolts.

[0018] Specific embodiment: A thin film grabbing and conveying mechanism is a device used for accurately conveying thin films or triangles, comprising a servo linear drive mechanism and a glue grabbing device. The glue grabbing device comprises a glue grabbing mechanism and a degumming mechanism. The glue grabbing device is mounted on the servo linear drive mechanism via a bracket. The bracket is provided with a slider with adjustable position and angle. The glue grabbing mechanism and the degumming mechanism are fixed to the slider. The glue grabbing mechanism comprises a glue grabbing lifting guide cylinder, a suction cup mounting plate, and a suction cup. The glue grabbing lifting guide cylinder is fixed to the slider via bolts. The suction cup mounting plate is fixed to the end face of the glue grabbing lifting guide cylinder. The suction cup is mounted on the suction cup mounting plate. The tail end of the suction cup is connected to a vacuum tube and has a strong adsorption force. A fixing pin is provided in the middle of the suction cup. The fixing pin is used to accurately adsorb and position the film. The degumming mechanism comprises a degumming lifting guide cylinder, a suction cup mounting plate, and a suction cup. The degumming lifting guide cylinder is fixed to the slider via bolts. The degumming device mounting plate is fixed to the end face of the degumming lifting guide cylinder. The degumming device is mounted on the degumming device mounting plate.

[0019] During operation, the glue grabbing mechanism is driven downward by the glue grabbing lifting guide cylinder. After the vacuum is connected to the suction cup, the film is adsorbed on the suction cup and the fixed needle accurately positions the film. After the adsorption and positioning action is completed, the glue grabbing lifting guide cylinder is lifted, and the servo linear drive mechanism begins to operate, achieving precise length and conveying of the film. After reaching the required position, the glue grabbing lifting guide cylinder descends again. Once in place, the degumming mechanism implements the film separation action. The degumming lifting guide cylinder drives the degumming device downward and simultaneously cuts off the vacuum adsorption. The degumming device pushes the film away. After the action is completed, the glue grabbing lifting guide cylinder and the degumming lifting guide cylinder are retracted simultaneously. After retraction into place, the servo linear drive mechanism returns, completing the entire conveying action.
