The stamping machine body is started, driving the upper die to move downward, and jointly acting with the lower die to make the parts to be processed extruded and formed.

[0004] The existing Chinese patent application with the publication number CN114179067A discloses a flip-type automatic grasping manipulator, which includes a clamp head part and a flip clamp part.

[0041] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0042] 1. In the high-speed precision gear transmission mechanism and the turning paper collecting machine based on it, the design of the lower rotating rod, on the one hand, can drive the adsorbed paper and other items to move up and down by driving the lower rotating rod to move up and down through the lifting electric cylinder, so as to realize the adsorption and placement operations of the paper and other items. On the other hand, the adsorbed paper and other items can be driven to turn and the electrostatic chuck for adsorbing the next paper and other items can be reset by driving the driving gear and the lower rotating rod to rotate through the transmission gear, improving the efficiency of turning and transporting the paper and other items. And when the transmission gear drives the electrostatic chuck to turn, it can also drive the cleaning sponge to turn, clean the lens part of the high-definition camera module, reduce the probability of dust and other impurities sticking to the lens part of the high-definition camera module, ensure that the high-definition camera module can perform high-definition camera operations, and improve the intelligent degree of transporting the paper and other items;

[0043] 2. In the high-speed precision gear transmission mechanism and the turning paper collecting machine based on it, when adsorbing and transporting the paper and other items, due to the particularity of the paper and other items, an electrostatic chuck is generally used to generate static electricity to adsorb and fix the paper and other items. At this time, an adsorption plate, an air extraction unit, He air holes and a thimble are installed at the bottom of the electrostatic chuck through an insulating layer. A certain gap is left between the adsorption plate and the paper and other items through the thimble. On the one hand, the flow rate of the air flow inside the air extraction unit and the He air holes is controlled, and on the other hand, it is ensured that static electricity and the flowing gas can move normally between the adsorption plate and the paper and other items, which can effectively prevent the paper and other items from deforming during the adsorption process, disperse the adsorption pressure of the electrostatic chuck, reduce the pressure difference between the upper and lower surfaces of the paper and other items, and thus protect the flatness of the adsorbed paper and other items. At the same time, the formed gap (buffer layer) can avoid the direct contact between the chuck and the paper and other items, thus avoiding the adsorbed paper and other items from being scratched or damaged, enabling the paper and other items to be sucked up flatly without direct contact with the electrostatic chuck;

[0044] 3. In a high-speed precision gear transmission mechanism and a turnover sheet stacker based thereon, through the design of the internal circulation cooling channel and heating electrodes of the electrostatic chuck, a constant temperature can be provided for the operation of the electrostatic electrodes, ensuring that when the electrostatic electrodes generate static electricity during operation to adsorb items such as paper, they will not be damaged due to long-term operation (high temperature), and the movement speed of electrons inside the electrostatic electrodes will not slow down due to low temperature, ensuring that the internal resistance of the electrostatic electrodes remains in a stable state and the charge-discharge performance of the electrostatic electrodes is guaranteed.

[0045] 4. In a high-speed precision gear transmission mechanism and a turnover sheet stacker based thereon, when driving items such as paper for transportation and turning, they are all driven by the way of gear meshing connection. The way of gear meshing can improve the stability of driving items such as paper for transportation and turning. At the same time, the electrostatic chuck for adsorbing items such as paper is far from the base. The way of gear meshing connection can bear a large load and will not cause problems such as damage or even fracture of the device due to the rotational force during transportation and turning, facilitating the continuous operation of transporting and turning items such as paper.

At this time, by starting the operation of the second motor 6052, the longitudinal steering block 6053 and the high-definition camera module 6054 connected to the output end of the second motor 6052 can be driven to rotate and move to the side of the cleaning sponge 5063. Then, when transporting the next group of items, the longitudinal steering block 6053 needs to rotate to position and adsorb the items on the previous production line. The driving force for rotating the longitudinal steering block 6053 will drive the cleaning sponge 5063 to rotate, and the cleaning operation of the lens part of the cleaning camera module 6054 can be completed without disassembling and stopping the transportation operation.

[0084] In the high-speed precision gear transmission mechanism of the present invention, when the driving gear 507 rotates, due to the design of the side groove 6041, the lower rotating rod 604 provided inside it will be driven to rotate, and then drive the electrostatic chuck 20 connected to the bottom of the lower rotating rod 604 through the lower mounting base 605 and the lower rotating block 606 to perform a vertical rotation operation. Among them, the lower rotating rod 604 is rotatably connected to the bottom of the lower turntable 603 and will not affect the output end of the lifting electric cylinder 602. At the same time, when transporting items, it is necessary to drive the electrostatic chuck 20 to move up and down to realize the adsorption and placement operations of the items. At this time, the lifting electric cylinder 602 is started to operate, driving the lower turntable 603 connected to the output end of the lifting electric cylinder 602 to move up and down, and driving the lower rotating rod 604, the lower mounting base 605, the lower rotating block 606 and the electrostatic chuck 20 connected to the bottom of the lower turntable 603 to move up and down. When the lower rotating rod 604 moves up and down, the lower rotating rod 604 can slide inside the driving gear 507 under the action of the side groove 6041, and the rotation and up and down movement of the lower rotating rod 604 will not conflict.

[0085] In the present invention, specifically refer to Figure 11, there are multiple circulating cooling channels 201 inside the electrostatic chuck 20. A coolant is circulated and transported inside the circulating cooling channels 201, and the electrostatic electrodes 202 of the adsorbed articles are cooled by the coolant. There are multiple electrostatic electrodes 202, and the multiple electrostatic electrodes 202 are all electrically connected to the electrostatic control module 200. The multiple electrostatic electrodes 202 are arranged inside the electrostatic chuck 20, and the electrostatic electrodes 202 are also connected to the heating electrodes 203, and the heating electrodes 203 are installed inside the electrostatic chuck 20.

[0086] Through the above structure, the design of the circulating cooling channels 201 and the heating electrodes 203 is mainly used for the overall temperature control of the electrostatic chuck 20. The simultaneous operation of the circulating cooling channels 201 and the heating electrodes 203 can keep the electrostatic electrodes 202 at a stable temperature, ensuring that when the electrostatic electrodes 202 generate static electricity to adsorb articles during operation, it is not easy to cause damage to the electrostatic electrodes 202 due to long-term operation.

[0087] Embodiment 2

[0088] On the basis of the above embodiment, it is found during use that when the electrostatic chuck 20 controlled by the electrostatic control module 200 performs adsorption and transfers articles such as paper, since the articles such as paper are processed on the production line, some debris or dust and other particulate impurities will remain on their surfaces. During the adsorption process of these particles on the articles such as paper, it will affect the adsorption effect of the articles such as paper, resulting in the adsorbed articles such as paper being prone to falling during the process of driving the articles such as paper to be transported and turned due to the vibration force generated during the process.

[0089] Therefore, specifically referring to Figure 12 , a plurality of insulating layers 70 are arranged at the inner bottom of the electrostatic chuck 20. An adsorption plate 701 located below the electrostatic chuck 20 is installed on the side of the insulating layer 70. A plurality of air extraction units 702 are formed inside the adsorption plate 701. The air extraction units 702 do not contact the paper. The air extraction units 702 are arranged on the side of the insulating layer 70 and are electrically connected to the electrostatic control module 200; a plurality of He air holes 703 are formed inside the insulating layer 70 and the adsorption plate 701. The He air holes 703 are arranged on the side of the air extraction units 702. The He air holes 703 are in contact with the paper. The electrostatic control module 200 controls the opening and closing of the He air holes 703 through the air extraction units 702. A thimble 704 is arranged between two adjacent He air holes 703, and the thimble 704 is in contact with the paper.

[0090] In the high-speed precision gear transmission mechanism of the present invention, the design of the insulating layer 70 can ensure that the static electricity emitted by the static electrode 202 is concentrated at multiple positions of the adsorption plate 701, improving the concentration of static electricity at the same position and the effect of adsorbing articles. The air extraction unit 702 can detect each area of the adsorbed article, and generate an air extraction force to adsorb the article by driving the extraction of the gas inside the He air hole 703 through the air extraction unit 702. The design of the ejector pin 704 can ensure that the article does not closely adhere to the bottom of the adsorption plate 701, leaving a certain space for gas and static electricity, and ensuring that the article can be adsorbed on the bottom of the adsorption plate 701.
