Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, and more specifically, to a vacuum suction cup. In addition, the utility model also relates to an automatic detection equipment comprising the vacuum suction cup. Background Art

[0002] Products usually need to be tested before leaving the factory to detect quality problems in a timely manner, thereby ensuring the reliability and stability of the products. Plate-shaped products often need to be flattened during the inspection process so that they can be inspected by taking photos or using laser sensors. At present, in order to flatten the products, vacuum suction cups are installed on the assembly line. The inside of the vacuum suction cup usually has a long vacuum cavity along its length, and a number of first adsorption holes are opened on the top plate of the vacuum suction cup. The first adsorption holes are usually spread throughout the entire top plate of the vacuum cavity. When in use, a vacuum environment is created in the vacuum cavity so that the product passing through the top of the vacuum suction cup becomes flat under the action of the adsorption force.

[0003] In order to make the entire product flat, the arrangement area of ​​the first adsorption holes is usually slightly smaller than the product, and the vacuum suction cup is often required to cover all the first adsorption holes with the product during use. However, the product will usually warp under its own stress, making it very likely that the product cannot be adsorbed when passing through the vacuum suction cup.

[0004] In summary, how to improve the adsorption capacity of the vacuum suction cup is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0036] like Figures 1 to 3 As shown, a plurality of vacuum chambers 101 are provided inside the suction cup body 1, such as two, three or four, etc. The vacuum chamber 101 may be a rectangular chamber or a circular chamber, etc., and the vacuum chambers 101 are arranged in parallel along the X direction, and the sum of the widths of the vacuum chambers 101 along the X direction is less than or equal to one Nth of the product. It should be noted that the plurality of vacuum chambers 101 may be the same, or different, or some may be the same and the remaining parts may be different.

[0037] Furthermore, a plurality of first adsorption holes 103 are provided above the suction cup body 1, and the first adsorption holes 103 are grouped and connected to the corresponding vacuum chamber 101 to more stably adsorb the product. It should be noted that there is no limit to the arrangement of the plurality of first adsorption holes 103, and they can be arranged uniformly or randomly, etc. Preferably, the plurality of first adsorption holes 103 are uniformly arranged in a matrix, for example, the first adsorption holes 103 are arranged in a plurality of concentric circles, and the arrangement of the plurality of groups of first adsorption holes 103 connected to the corresponding vacuum chamber 101 can be the same or different, or some groups adopt the same arrangement and the remaining groups adopt different arrangement, etc.

[0039] When in use, the suction cup body 1 is connected to the vacuum system to drive the product to move from left to right, so that when the product passes over the suction cup body 1 along the X direction, the product will first be adsorbed by the vacuum cavity 101 along the outer side of the left end of the suction cup body 1, and finally by the vacuum cavity 101 along the outer side of the right end of the suction cup body 1.

[0042] In some possible embodiments, the number of vacuum chambers 101 is three, and the three vacuum chambers 101 are arranged in parallel along the X direction. When in use, the product is driven to move from left to right, so that when the product passes above the suction cup body 1 along the X direction, the product will pass through the first, second, third, fourth, fifth and sixth states in sequence. Specifically, in the first state, the product covers a number of first suction holes 103 connected to the leftmost vacuum chamber 101 and the second suction holes 104 located on the left side. In the second state, the product covers a number of first suction holes 103 connected to the leftmost and middle vacuum chambers 101.

The inner concave of the leftmost group of first adsorption holes 103 in a "concave" shape is located in the middle of the left side, and the inner concave of the rightmost group of first adsorption holes 103 in a "concave" shape is located in the middle of the right side, and second adsorption holes 104 are opened at the above two concave positions.

[0046] When using, Figure 4 Taking the orientation as a reference, the product moves from left to right, and the right end of the product will first move to the position of the second adsorption hole 104 on the left. At this time, the second adsorption hole 104 can adsorb the middle position of the right end of the product, and the first adsorption holes 103 located on the upper and lower sides of the second adsorption hole 104 will adsorb the upper and lower positions of the right end of the product. Similarly, the left end of the product moves to the position of the second adsorption hole 104 on the right. At this time, the second adsorption hole 104 can adsorb the middle position of the left end of the product, and the first adsorption holes 103 located on the upper and lower sides of the second adsorption hole 104 will adsorb the upper and lower positions of the left end of the product. With this arrangement, the vacuum suction cup can ensure the ability to adsorb products with larger deformation in the middle position while reducing energy loss.
