[0021] The two suction holes 9 on each suction head 8 are each connected to one end of a vacuum passage 10 provided on the suction head 8, and the other end of the vacuum passage 10 is connected to a vacuum generator 11 via a pipeline.

[0023] Example 2: A high-precision material picking and unloading device comprises: a supporting vertical plate 1, a plurality of sliding seats 5 spaced apart in sequence are provided on one side of the supporting vertical plate 1, each of the sliding seats 5 that can move in the vertical direction is mounted on the supporting vertical plate 1 by a slide rail 61 and a slider 62 that cooperate with each other, a cylinder 7 is correspondingly provided above each of the sliding seats 5, the lower end of the piston rod of the cylinder 7 is connected to the upper end of the corresponding sliding seat 5, and a suction head 8 is installed at the lower end of each of the sliding seats 5, one end of the horizontal part 81 of the suction head 8 is connected to the sliding seat 5, and the lower surface of the vertical part 82 of the suction head 8 at the other end of the horizontal part 81 is provided with two adsorption holes 9 spaced apart along the length direction of the product 100 to be picked up, the shape of each of the adsorption holes 9 is the same as the shape of the product 100 to be picked up, and the area ratio between each adsorption hole 9 and the product 100 to be picked up is 1:3.5.

[0024] The two suction holes 9 on each suction head 8 are each connected to one end of a vacuum passage 10 provided on the suction head 8, and the other end of the vacuum passage 10 is connected to a vacuum generator 11 via a pipeline. The sliding base 5, suction head 8, and vacuum generator 11 are each provided with eight of them.

[0025] It also includes a manipulator 3 mounted on the base 2, and the support plate 1 is mounted on the clamping head 31 of the manipulator 3; at least two spaced L-shaped support blocks 4 are connected between the surface of the other side of the support plate 1 and the clamping head 31 of the manipulator 3;

[0026] A visual positioning assembly 122 located above the suction head 8 is installed on the clamping head 31 of the above-mentioned manipulator 3 through a bracket 121; the above-mentioned cylinders 7 are each installed on the supporting vertical plate 1 through a support base 71; the above-mentioned cylinders 7 are pen-shaped cylinders.

[0027] Working principle:

[0028] First, the piston rods of each cylinder are placed in the initial retracted state, and the sliding seat drives the suction head to the highest position of its stroke;

[0029] Then, the various components on the chuck are driven by the manipulator to move until they are above the product to be picked up and placed. The multi-axis manipulator here is purchased and belongs to the scope of existing technology, so it will not be described in detail.

[0030] The visual positioning component takes photos to locate a batch of products to be picked up and placed, and then controls the robot to adjust the position of the suction head based on the results, thereby ensuring the relative position accuracy between the suction head and the products to be picked up and placed, so that each suction head is directly above the corresponding product before picking up the product;

[0031] The piston rods of the various cylinders are driven simultaneously or sequentially from a contracted state to an extended state, thereby driving the suction head on the sliding seat to move downward until its lower end surface with the suction hole is in contact with the upper surface of the corresponding product. Then, the vacuum generators corresponding to the suction heads are activated one by one, and the negative pressure generated in the suction holes on the vertical part is used to suction and position the surface of one side of the product to be picked up. While realizing batch picking and placing of products, the independent control of the vertical position of each suction head improves the precision and accuracy of product picking and can also avoid adverse interference with other products picked up and placed in the same batch.

[0032] By using two contoured adsorption holes spaced apart along the length of the product and controlling the size of the adsorption holes to match the product, we can prevent air leakage caused by excessive adsorption holes, which can lead to insufficient adsorption force, and also avoid damage to the product caused by excessive adsorption force, thereby improving the stability of tiny product positioning and the uniformity of product force.

[0033] When the above-mentioned high-precision picking and placing device is used, while realizing batch picking and placing of products, the precision and accuracy of adsorption and picking of products are improved by independently controlling the vertical position of each suction head, and adverse interference with other products picked and placed in the same batch can be avoided. It is also conducive to forming an adsorption force that matches the product, avoiding insufficient adsorption force that causes force deflection of the product during subsequent processing, and avoiding damage to the product due to excessive adsorption force, thereby improving the stability of product adsorption positioning and the uniformity of product force.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
