Description

Technical Field

[0001] The utility model relates to the technical field of pulp molding products, in particular to automatic punching and loading and unloading equipment for paper and plastics. Background Art

[0002] Pulp molding products are new environmentally friendly paper products. Paper-plastic products are mostly used as packaging boxes for electronic products. With the diversification of market demand, paper-plastic products are no longer limited to trimming and cutting. New product function designs have added punching technology. The current punching process of paper-plastic products is as follows: the operator takes the product to be punched from the assembly line, places it on the positioning fixture on the punching machine, presses the start button, and the punching machine starts. After the punching is completed, the finished product after punching is taken manually and placed on the assembly line to flow into the next process. Manual punching is not only labor-intensive but also requires continuous investment of a large amount of human resources, resulting in increased labor costs. Manual punching is prone to hole position deviation, resulting in increased defective rate. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely 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, rather than all of the embodiments.

[0022] See also Figures 1 to 4The utility model provides a technical solution: an automatic punching and loading and unloading device for paper and plastic, comprising a bracket 1 and a table 2, a parallel robot 3 is installed inside the bracket 1, a suction cup 4 is installed below the parallel robot 3, the parallel robot 3 comprises three pairs of connecting rods and a motor, the three pairs of connecting rods can change the position of the suction cup 4 when working, the motor can change the angle of the suction cup 4, a punching assembly 5 is installed above the table 2, the punching assembly 5 comprises a bottom plate 501, a linear guide 502 is installed in the middle position of the upper surface of the bottom plate 501, and a movable front guide 502 is installed above the linear guide 502 through a slider A push plate 503 moves backward, a punch head 504 is installed behind the push plate 503, a cylinder 505 connected with a piston rod and the push plate 503 is installed in front of the bottom plate 501, and a positioning fixture 506 is installed behind the bottom plate 501. When the punching assembly 5 is working, the cylinder 505 pushes the push plate 503 to move backward, and at the same time, the punch head 504 is pushed into the positioning fixture 506 to realize punching. A feeding belt line 6 is installed on one side of the punching assembly 5, and a unloading belt line 7 is installed on the other side of the punching assembly 5. The product 8 to be punched is placed above the feeding belt line 6, and the product 8 to be punched is placed above the unloading belt line 7. There are punched products 9, the height at which the products 8 to be punched are placed on the loading belt line 6, the height at which the punched products 9 are placed on the unloading belt line 7, and the height at which the products 8 to be punched are placed in the positioning fixture 506 are basically the same, which can reduce the movement stroke of the parallel robot 3 and improve efficiency. A visual camera 10 is installed above the bracket 1. The products 8 to be punched are placed as neatly as possible according to the requirements, that is, the placement posture is as convenient as possible for the parallel robot 3 to grab the positioning fixture 506, and the placement position is as close as possible to the middle of the visual camera 10. A certain distance is set between the products 8 to be punched. The ends of the loading belt line 6 and the unloading belt line 7 are inserted into the interior of the bracket 1, so that the parallel robot 3 can grab the product 8 to be punched from the loading belt line 6, and the parallel robot 3 can put the punched product 9 on the unloading belt line 7.

During this process, the punching head 504 passes through the product 8 to be punched to complete the punching, and further the cylinder 505 resets and at the same time the parallel robot 3 drives the suction cup 4 to take the punched product 9 from the positioning tooling 506 and put it on the unloading belt line 7, and further the unloading belt line 7 works to transport the punched product 9 out of the bracket 1, and further the worker takes the punched product 9 away. During this process, the worker cannot put his hand into the bracket 1, and the parallel robot 3 will stop working if the safety window is opened or the safety grating detects a mobile phone.

[0024] To sum up, the paper plastic automatic punching loading and unloading equipment automatically grabs the product 8 to be punched from the loading belt line 6 to the punching assembly 5 for automatic punching through the parallel robot 3, and then automatically grabs the punched product 9 to the unloading belt line 7 through the parallel robot 3. Workers only need to load and unload materials, which not only reduces the labor intensity of workers but also reduces personnel allocation and thus reduces labor costs. The parallel robot 3 drives the suction cup 4 to gently pick up and place the product, which can avoid product deformation and thus avoid position deviation in punching. The force of the punching assembly 5 when punching the product is controlled within a certain range, which can avoid deformation of the hole due to excessive or insufficient force, thereby greatly reducing the defective rate.
