Description

Technical Field

[0001] The utility model relates to the technical field of sample handling during testing, in particular to a non-contact material suction device. Background Art

[0002] At present, when testing mirror product samples after vacuum coating, pneumatic grippers or vacuum negative pressure suction cups are usually used to contact and place samples. However, when pneumatic grippers are used to clamp samples, their clamping force will be affected by air pressure, and there will be an unstable phenomenon of fluctuating, which may easily cause the sample to deform or fall. When ordinary suction cups are used to absorb bright mirror samples, they are likely to leave suction cup marks on the mirror surface of the product sample, causing sample loss.

[0003] Therefore, it is necessary to provide a novel non-contact material suction device to solve the above problems existing in the prior art. Utility Model Content

[0009] Furthermore, a pressure gauge is provided on the first filter.

[0010] Furthermore, a pressure reducing valve is also provided on the first filter.

[0011] Furthermore, the filtering module also includes a second filter, which is connected to the first filter. The second filter is used to filter out liquid or gas impurities in the gas filtered by the first filter, and output the gas filtered by the first filter and the second filter in sequence to the Bernoulli suction cup.

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the utility model belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0022] At present, the commonly used suction method is contact suction, which will leave marks on the surface of the bright mirror product. The utility model designs a non-contact suction device and adopts a Bernoulli suction cup. It uses the Bernoulli principle to blow air into the suction cup to form an air pressure difference to absorb the items. At the same time, by setting a filter module on the air inlet side, the dust and water vapor in the gas are filtered, so that when the gas blown out of the suction cup flies in all directions, it will not damage the surface of the mirror product, so as to better protect the surface of the bright product.

[0023] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] refer to Figure 1 The material suction device of the utility model comprises a Bernoulli suction cup 16 connected to an air source and a filter module 17 .

[0025] The Bernoulli suction cup 16 is connected to the gas source through the gas pipe 14. The filter module 17 is arranged on the gas pipe 14 between the gas source and the Bernoulli suction cup 16. The filter module 17 is used to filter out impurities in the gas input into the filter module 17 from the gas source.

[0026] The gas inputted by the gas source is usually air. The following is explained by taking air as an example of the gas that makes the Bernoulli suction cup 16 produce adsorption force.

[0027] refer to Figure 2-Figure 3 In some embodiments, the Bernoulli suction cup 16 is provided with an air inlet 161 and an air outlet 162. The Bernoulli suction cup 16 is connected to the air pipe 14 through the air inlet 161. A plurality of air outlets 162 are provided along the side walls around the suction end surface 163 of the Bernoulli suction cup 16. The Bernoulli suction cup 16 is a non-contact suction cup that uses compressed air entering from the air inlet 161 to generate a high-speed jet through the air outlet 162, and the high-speed jet takes away the surrounding gas, thereby generating negative pressure to absorb the object.

[0028] The Bernoulli suction cup 16 can form a high-speed jet, which can be used to suck the product (the object to be sucked). When sucking general products through the Bernoulli suction cup 16, the product will generally not be damaged during the suction process, and the required stable transportation function will be well achieved. However, when sucking mirror products, if the compressed air is not treated, the airflow will become a high-speed jet when passing through the Bernoulli suction cup 16, which will leave marks (bright marks) on the surface of the mirror product, and even damage (scratch) the surface of the product.

[0029] Therefore, the utility model solves the above problem well by providing a filter module 17 for filtering and removing impurities such as fine dust and water vapor in the air input from the air source to the filter module 17 through the air pipe 14.

[0030] refer to Figure 1 In some embodiments, the filter module 17 includes a first filter 19. The first filter 19 is used to filter out solid impurities such as fine dust in the air input from the air source, and output the filtered air to the Bernoulli suction cup 16 through the air pipe 14.

[0031] In some embodiments, a barometer 11 is provided on the first filter 19. The value displayed on the barometer 11 represents the magnitude of the air pressure, and the pressure of the air input from the air source can be adjusted by the value displayed on the barometer 11 to control the magnitude of the air pressure.

[0032] In some embodiments, a pressure reducing valve 12 is further provided on the first filter 19. According to the pressure value displayed by the barometer 11, the pressure reducing valve 12 is used to adjust the air pressure.

[0033] refer to Figure 1 In some embodiments, the filter module 17 further includes a second filter 18. The second filter 18 is connected to the first filter 19 and is located on the side of the first filter 19 away from the air source. The second filter 18 is used to filter out liquid or gas impurities, such as water vapor or oil droplets, in the air filtered by the first filter 19. It will better filter out the residues in the air and prevent the product surface from being damaged by impurities in the unfiltered air, thereby better protecting the bright product surface. The clean and dry air filtered by the first filter 19 and the second filter 18 in sequence will continue to be output to the Bernoulli suction cup 16 through the second filter 18.

[0034] In some embodiments, the first filter 19 may be a mesh filter. The second filter 18 may be an oil-water separation filter capable of filtering oil and water vapor.

[0035] In some embodiments, the first filter 19 and the second filter 18 can be combined to form a pneumatic two-piece structure filter module 17. After adding the pneumatic two-piece, the Bernoulli suction cup 16 will not leave marks on the surface of the product when sucking any product, nor will it damage the surface of the product, so it can well protect the surface of the product, improve the yield in the production process, and reduce waste.

[0036] refer to Figure 1 . In some embodiments, a throttle valve 13 is provided on the air pipe 14 between the filter module 17 (second filter 18) and the Bernoulli suction cup 16. The air filtered by the filter module 17 will first be regulated by the throttle valve 13, and then flow to the Bernoulli suction cup 16. By setting the throttle valve 13, the rate of the airflow to the Bernoulli suction cup 16 can be controlled to prevent the flow rate from being too fast. The airflow controlled by the throttle valve 13 reaches the air inlet 161 on the Bernoulli suction cup 16, and enters the airway in the Bernoulli suction cup 16 from the air inlet 161, and then is ejected through the air outlet 162 on the Bernoulli suction cup 16 connected to the airway, and becomes a high-speed jet. The high-speed jet takes away the surrounding gas to form a vacuum adsorption area, thereby realizing non-contact absorption of the product through negative pressure.

[0037] refer to Figure 4 and Figure 1 In some embodiments, a limiting unit is provided on the outer circumference of the Bernoulli suction cup 16 . The limiting unit is used to limit the side position of the adsorbed object (product) on the Bernoulli suction cup 16 .

[0038] In some embodiments, the limiting unit includes a supporting bracket 15 disposed on the outer periphery of the Bernoulli suction cup 16 , and the supporting portion 152 of the supporting bracket 15 is exposed at the adsorption end surface 163 of the Bernoulli suction cup 16 .

[0039] In some embodiments, the support bracket 15 includes a plurality of support units 151 arranged along the circumference of the Bernoulli suction cup 16. A support portion 152 is provided on the support unit 151, and the lower end of the support portion 152 is exposed to the adsorption end surface 163 of the Bernoulli suction cup 16. By providing the support bracket 15, the product adsorbed by the Bernoulli suction cup 16 in a non-contact manner can be relatively fixed laterally to prevent the product from sliding, thereby adsorbing the product more stably and safely.

[0040] In some embodiments, a buffer slope 153 is provided on the inner support surface of the support portion 152 to guide the product when it is adsorbed.

[0041] When the utility model is used, the compressed air from the air source passes through the filter of the filter module 17 (pneumatic two-piece) to filter out impurities in the air, and the pressure gauge 11 and the pressure reducing valve 12 are used to control the air pressure. The filtered air will first pass through the throttle valve 13 along the air pipe 14 to control the air flow rate, and then flow to the Bernoulli suction cup 16. After the airflow reaches the Bernoulli suction cup 16, it passes through the small hole (air outlet 162) on the Bernoulli suction cup 16 and is ejected into a high-speed jet. The high-speed jet takes away the surrounding gas to form a vacuum to absorb the product.

[0042] After adding the pneumatic two-piece, the Bernoulli suction cup 16 will not leave marks on the surface of the object or even damage the surface of the object when sucking any product. It can well protect the surface of the product, improve the yield in the production process, and reduce waste.

[0043] The movement of the Bernoulli suction cup 16 can be controlled by a manipulator to achieve adsorption and non-contact placement of product test samples.

[0044] In summary, the suction device of the utility model can use the Bernoulli principle to blow air into the suction cup to form an air pressure difference by setting the Bernoulli suction cup 16, so as to absorb the product in a non-contact manner, and avoid adsorption marks on products with bright mirror surfaces. In addition, by setting the filter module 17, impurities in the air input by the air source can be filtered out to prevent the products with mirror surfaces from being damaged by impurities in the air flow, thereby avoiding damage to the mirror surface of the product, thus playing a good role in protecting the surface of the bright product, improving the yield in the production process, and reducing waste. Based on the special adsorption principle and stable performance of the Bernoulli suction cup 16, the utility model can be widely used in the fields of photovoltaic cells, PCBs, etc.

[0045] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
