By using a camera to identify feature points on the product surface that are easy to identify and convenient for positioning, and using a vacuum adsorption platform for the platform where the product is placed to prevent the product from moving during production.

[0003] The current positioning and recognition method uses a camera to identify the marked points on the product surface. The coaxial light or bar light source is on the same side as the camera.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will describe in detail the embodiments of the present utility model with reference to the accompanying drawings.

[0026] As Figures 1-6 shown, a vacuum adsorption platform for detecting high light-transmitting products includes a bottom plate 1 and a light-transmitting suction cup 2 installed on the base. A plurality of vacuum adsorption holes 21 arranged in an array are formed on the surface of the light-transmitting suction cup 2, and a plurality of air pipe joints 22 communicating with the plurality of vacuum adsorption holes 21 are formed on one side of the light-transmitting suction cup 2; a light source assembly 3 corresponding to the light-transmitting suction cup 2 is installed at the bottom of the bottom plate 1, the light source assembly 3 and the light-transmitting suction cup 2 are arranged on opposite sides of the bottom plate 1, and a light-passing through groove 11 for transmitting the light path of the light source assembly 3 to the light-transmitting suction cup 2 is formed on the bottom plate 1.

[0027] The light source assembly 3 is arranged facing the light-transmitting suction cup 2, and the light source assembly 3 is used to irradiate the light-transmitting suction cup 2. The light-transmitting suction cup 2 is used to load products, and under the action of a number of vacuum suction holes 21, the products loaded on the surface of the light-transmitting suction cup 2 are adsorbed, realizing the stable setting of the products on the light-transmitting suction cup 2, and through the light-transmitting suction cup 2, the light source assembly 3 realizes the stable illumination of the products adsorbed on the light-transmitting suction cup 2.

[0028] A cavity is formed inside the light-transmitting suction cup 2, and the cavity is connected to a number of vacuum suction holes 21. An air extraction pipe communicating with an air pump is installed on the air pipe joint 22. Under the action of the air pump and the air extraction pipe, the inside of the light-transmitting suction cup 2 is evacuated, so that a negative pressure is formed inside the light-transmitting suction cup 2, and thus an adsorption force with the products is formed by the vacuum suction holes 21. Under the action of a number of vacuum suction holes 21, the products are adsorbed and arranged on the surface of the light-transmitting suction cup 2.

[0029] The light-transmitting suction cup 2 is made of optical glass. The surface of the light-transmitting suction cup 2 forms a high-precision flatness and has good light transmittance, which can ensure the fitting degree when the products are adsorbed on the surface of the light-transmitting suction cup 2. The light generated by the light source assembly 3 can be irradiated on the light-transmitting suction cup 2 through the light passing groove 11.

[0030] The light passing groove 11 is arranged along the length direction of the light source assembly 3, and a number of vacuum suction holes 21 arranged in an array are arranged along the length direction of the light passing groove 11.

[0031] The positions of the light source assembly 3, the light passing groove 11 and a number of vacuum suction holes 21 correspond to each other, which is convenient for the optical path of the light source assembly 3 to be irradiated on the products adsorbed at the vacuum suction holes 21 through the light passing groove 11.

[0032] The vacuum suction holes 21 are as small as possible during the design process to ensure that when the products are negatively adsorbed by the vacuum suction holes 21, the products will not be deformed due to excessive pressure. And the size of the vacuum suction holes 21 needs to be smaller than the size of the feature points recognized by vision, to avoid the misrecognition of the vacuum suction holes 21 by vision and prevent the vacuum suction holes 21 from coinciding with the feature points, resulting in inaccurate recognition.

[0033] A light-transmitting plate 4 for positioning and installing the light-transmitting suction cup 2 is provided on the bottom plate 1. The light-transmitting plate 4 covers the light passing groove 11, and a number of mounting holes 41 surrounding the light passing groove 11 are formed on the light-transmitting plate 4. A number of connecting holes 13 corresponding and communicating with the number of mounting holes 41 are formed on the bottom plate 1.

[0034] The light-transmitting plate 4 is made of optical glass material and has good light transmittance. The light-transmitting plate 4 is used in combination with the light-transmitting suction cup 2. During use, the light-transmitting suction cup 2 ensures good sealing performance of itself, so as to meet the requirements of negative pressure adsorption. While the light-transmitting plate 4 is used for light transmission, it is also used for positioning and installing the light-transmitting suction cup 2, so as to ensure that the light-transmitting suction cup 2 is always fixedly connected to the bottom plate 1 through the light-transmitting plate 4.

[0035] A sunken groove 12 for positioning and installing the light-transmitting plate 4 is formed on the surface of the bottom plate 1. The light-transmitting plate 4 is snap-fitted in the sunken groove 12. When the light-transmitting plate 4 is snap-fitted in the sunken groove 12, the side of the light-transmitting plate 4 abuts against the bottom plate 1 at this time, realizing the preliminary positioning of the light-transmitting plate 4. And at this time, a plurality of mounting holes 41 correspond to a plurality of connecting holes 13 one by one, which is convenient for subsequent fixing connection between the light-transmitting plate 4 and the bottom plate 1 through bolts. The bottom of the light-transmitting suction cup 2 is formed with bolt holes corresponding to the mounting holes 41. The bolt holes are blind hole structures that do not affect the inner cavity of the light-transmitting suction cup 2, so that the light-transmitting suction cup 2 can be fixedly connected to the light-transmitting plate 4 under the action of bolts.

[0036] Positioning members 31 for fixing the light source assembly 3 are formed at both ends of the light source assembly 3. Positioning holes 32 communicating with the connecting holes 13 are formed on the positioning members 31. The light source assembly 3 can be a lamp strip structure. The light source assembly 3 generates light under the action of power on. The positioning members 31 are arranged at both ends of the light source assembly 3. Under the action of the positioning members 31, the light source assembly 3 is fixed on the bottom of the bottom plate 1. The positioning members 31 can be hoop structures.

[0037] A support suction cup 5 installed overhead is mounted on the bottom plate 1. A plurality of support adsorption holes 51 are formed on the surface of the support suction cup 5, and the surface of the support suction cup 5 is flush with the surface of the light-transmitting suction cup 2. Thus, when the product is placed on the light-transmitting suction cup 2, the product can be adsorbed under the combined action of the support suction cup 5 and the light-transmitting suction cup 2.

[0038] The support suction cup 5 can be made of metal, which is used to adsorb the parts of the product that do not need to be visually recognized, and can realize the main adsorption of the adsorbed product under the action of the support suction cup 5, ensuring the stability of the product during the adsorption process.

[0039] A support block 6 for supporting the support suction cup 5 overhead is mounted on the bottom plate 1. An air pipe cavity 8 communicating with a plurality of air pipe joints 22 is formed between the support suction cup 5 and the bottom plate 1. The air pipes for negative pressure pumping of the vacuum adsorption holes 21 and the support adsorption holes 51 are installed in the air pipe cavity 8, so as to facilitate the routing and installation of the air pipes in the air pipe cavity 8.

[0040] The support block 6 is connected to the opposite sides of the support suction cup 5. The air pipe cavity is formed between the relatively arranged support blocks 6. The support block 6 is used to raise the height of the support suction cup 5 to ensure that the surface of the support suction cup 5 is flush with the surface of the light-transmitting suction cup 2.

[0041] A number of interconnected fastening holes 7 are formed on the support block 6, the bottom plate 1, and the support suction cup 5, and the support block 6, the bottom plate 1, and the support suction cup 5 can be fixedly connected by bolts.

[0042] An assembly hole 14 for driving the movement of the bottom plate 1 is formed on the bottom plate 1. The assembly hole 14 is used to be installed on a moving device. By driving the movement of the bottom plate 1 through the moving device, the movement of the product adsorbed on the light-transmitting suction cup 2 and the support suction cup 5 is driven, so that the product can be moved below the camera, and the product can be visually recognized by the camera.

[0043] During actual use, the product is adsorbed by the light-transmitting suction cup 2 and the support suction cup 5, and a light source assembly 3 for illuminating the back surface of the product is installed below the light-transmitting suction cup 2. The vision camera is arranged to recognize the front surface of the product. By using the principle of optics, the back surface of the product is made light-transmitting, so that some features inside or on the surface of the product can be detected by the front camera, and thus can be used as effective feature points that can be grasped during positioning, so as to meet the detection requirements for highly light-transmitting products.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model; therefore, the present utility model will not be limited to these embodiments shown herein, but rather will be accorded the widest scope consistent with the principles and novel features disclosed herein.
