DETAILED DESCRIPTION

[0023] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0024] Example 1: A wiping assembly, such as Figure 1 As shown, it includes: a cloth placing module 61, a cloth collecting module 62 and a wiping block 1, a wiping cloth 5 is wound around the cloth placing module 61, the wiping block 1 and the cloth collecting module 62, and the end of the wiping block 1 is provided with a wiping head 2 for contacting the product 100 to be wiped through the wiping cloth 5, and the area of ​​the wiping block 1 close to the wiping head 2 is provided with a plurality of liquid outlets 3 in contact with the wiping cloth 5 at intervals along the width direction of the wiping cloth 5. In the movement direction of the wiping cloth 5, the liquid outlet 3 is located on the side of the wiping head 2 close to the cloth placing module 61, and the liquid outlet 3 is connected to the liquid flow channel 4 provided in the wiping block 1, and this liquid flow channel 4 is connected to the liquid supply unit through a pipeline.

[0025] The aperture of the liquid outlet hole 3 is set to 0.1 mm, and the amount of wiping liquid can be further accurately controlled by utilizing the capillary effect of the liquid outlet hole;

[0026] like Figure 3 As shown, the wiping block 1 further includes a horizontal plate 11 and a bent plate 12 located at the end of the horizontal plate 11, and the wiping head 2 is arranged on the end of the bent plate 12 opposite to the horizontal plate 11;

[0027] The angle between the bent plate 12 and the horizontal plate 11 of the wiping block 1 is greater than 90°, so that the angle between the wiping head and the product to be wiped in the direction of movement of the wiping head is less than 90°, thereby improving the smoothness of wiping while protecting the product to be wiped;

[0028] The horizontal plate 11 of the wiping block 1 is mounted on a horizontal drive module. The horizontal drive module drives the wiping block to move the wiping head and the wiping cloth on its outer side horizontally from one end of the surface to be wiped on the product to be wiped to the other end, thereby wiping the liquid soaked on the wiping cloth onto the surface to be wiped.

[0029] like Figure 1 As shown, a plurality of guide rollers 63 are provided between the cloth placing module 61 and the wiping block 1, and between the wiping head 2 and the cloth collecting module 62, which are in rolling contact with the wiping cloth 5, so as to guide and reverse the wiping cloth 5;

[0030] The cloth placing module 61, cloth collecting module 62 and guide roller 63 are all mounted on a supporting side plate 7;

[0031] The wiping block 1 is provided with a liquid inlet 41 on both sides of the liquid flow channel 4. The two liquid inlets 41 communicating with the liquid flow channel 4 are each connected to the liquid supply unit via a pipeline.

[0032] like Figure 4 As shown, the liquid supply unit further includes: a liquid supply barrel 91 with built-in wiping liquid and a liquid supply pump 92. The liquid inlet end of the liquid supply pump 92 and the liquid supply barrel 91, and the liquid outlet end of the liquid supply pump 92 and the liquid flow channel 4 are connected by pipelines. The wiping liquid is alcohol. The alcohol in the liquid supply barrel 91 is pumped into the liquid flow channel through the liquid supply pump 92 through the pipeline, and then overflows through the liquid outlet hole 3 on the wiping block 1 to soak the wiping cloth 5 on the outside;

[0033] The wiping head 2 is a rubber wiping head, which can be realized by rubber coating. The use of a wiping head with a certain flexibility can not only improve the uniformity of the wiping force, but also avoid damage to the wiped object due to excessive wiping force. The wiping cloth 5 is a non-woven fabric.

[0034] like Figure 3 As shown, the wiping head 2 faces a surface of the product 100 to be wiped which is an arc surface.

[0035] Example 2: A wiping assembly, comprising: a cloth placing module 61, a cloth collecting module 62 and a wiping block 1, a wiping cloth 5 is wound around the cloth placing module 61, the wiping block 1 and the cloth collecting module 62, the end of the wiping block 1 is provided with a wiping head 2 for contacting the product 100 to be wiped through the wiping cloth 5, the area of ​​the wiping block 1 close to the wiping head 2 is provided with a plurality of liquid outlets 3 in contact with the wiping cloth 5 at intervals along the width direction of the wiping cloth 5, the liquid outlets 3 are located on the side of the wiping head 2 close to the cloth placing module 61 in the movement direction of the wiping cloth 5, the liquid outlets 3 are connected to the liquid flow channel 4 provided in the wiping block 1, and this liquid flow channel 4 is connected to the liquid supply unit through a pipeline.

[0036] The aperture of the liquid outlet holes 3 is set to 0.5 mm, and the direction of the liquid flow channel 4 is parallel to the direction of arrangement of the multiple liquid outlet holes 3 distributed at equal intervals, so that the connection distance between each liquid outlet hole and the liquid flow channel is the same, thereby improving the uniformity of the liquid in the liquid flow channel wetting the outer wiping cloth after overflowing from the liquid outlet hole;

[0037] The wiping block 1 is provided with at least two first stops 81 spaced apart along the direction of movement of the wiping cloth 5 and at least two second stops 82 opposite to the first stops 81. The wiping cloth 5 is movably disposed between the first stops 81 and the second stops 82 to limit the position of the wiping cloth during its movement, thereby preventing the wiping cloth from deviating and causing interference and damage to the product during contact with the product.

[0038] The liquid supply unit further comprises: a liquid supply barrel 91 containing a wiping liquid and a liquid supply pump 92. The liquid supply pump 92 has a liquid inlet connected to the liquid supply barrel 91 and a liquid outlet connected to the liquid flow channel 4 via pipelines. The liquid supply pump 92 can preferably be a peristaltic pump.

[0039] The above-mentioned wiping liquid is 90% ethanol. It should be noted that the selection of the wiping liquid is related to the physical and chemical properties of the surface of the product to be wiped. There is also a wide range of options for its type. It is preferred to choose a liquid that can evaporate quickly and leave no residue. It also needs to meet the requirements of being non-corrosive, not damaging the surface of the product to be wiped, and not causing serious harm to the human body.

[0040] The above-mentioned wiping head 2 is a PEEK wiping head, and the above-mentioned wiping cloth 5 is a dust-free cloth. The surface of the product 100 to be wiped facing the above-mentioned wiping head 2 is an arc surface. By wrapping an elastic dust-free cloth around its outside, a wiping surface that can apply force evenly and stably and can directly contact the coated surface of the glass product can be formed, so that the wiping cloth 5 on the outside of the wiping head 2 can more stably and effectively spread the alcohol evenly over the entire surface to be inspected during the moving wiping process, and at the same time ensure that the amount of alcohol liquid on the surface to be inspected is within a reasonable range, so that it can dissipate from existence to non-existence within a predetermined time, that is, leaving enough time for the camera to capture the above-mentioned complete process, thereby helping the visual system to complete the capture and analysis of the defect morphology, and laying a preliminary physical foundation for the accurate recognition of the deep learning algorithm.

[0041] Working Principle: Generally used for defect detection on the coated surface of glass products (such as the glass back panel of electronic products). The coated surface is the surface to be wiped and tested.

[0042] When in use, the rolled strip of wiping cloth is installed on the cloth placing module, and one end of the wiping cloth is passed around the wiping block and the wiping head in sequence and then installed on the cloth collecting module. The wiping cloth can be driven by the cloth collecting module to move from the cloth placing module to the cloth collecting module, so that during the movement, one side surface of the wiping cloth successively slides in contact with the liquid outlet area on the wiping block and the outer surface of the wiping head;

[0043] Liquid (such as alcohol) is injected into the liquid flow channel on the wiping block through a pipeline, and the liquid can overflow from the liquid outlet to soak the wiping cloth wrapped around the wiping block and outside the liquid outlet;

[0044] like Figure 2 As shown, the product to be wiped is loaded onto a movable carrier with the coated surface of the product to be wiped facing upward;

[0045] Before wiping, move the wiping cloth soaked in liquid on the outside of the liquid outlet a short distance to the outside of the wiping head;

[0046] At the same time, the coating surface is moved to the bottom of the wiping head, and the carrier is driven to move upward in the vertical direction or the wiping block is driven to move downward in the vertical direction so that the wiping cloth soaked on the outside of the wiping head contacts one end of the surface to be wiped;

[0047] Then, the wiping head and the wiping cloth outside it are driven by the wiping block to move horizontally to the other end of the surface to be wiped, so that the liquid soaked on the wiping cloth is wiped evenly and comprehensively on the surface to be wiped;

[0048] In the above-mentioned process of moving and wiping the surface to be wiped by the wiping cloth wrapped around the outside of the wiping head, the wiping cloth is soaked by the liquid overflowing from the multiple liquid outlets when it is close to the wiping head. The aperture of the liquid outlet 3 is set to a small hole of 0.1mm~1.0mm, and the capillary phenomenon of the liquid outlet is used to accurately control the amount of wiping liquid. When used with a wiping cloth of a specific material, the required liquid can be evenly covered on the wiping head, avoiding uneven and incomplete display of defects on the surface to be wiped. Compared with the traditional manual wiping or brush application method, the accuracy of defect detection on the coating surface after wiping can be greatly improved;

[0049] Furthermore, the wiping cloth will not drip due to excessive liquid soaking, nor will it be unable to fully wipe due to insufficient liquid soaking. It can also avoid the waste and overflow of the soaking liquid caused by premature soaking of the wiping cloth, as well as the volatilization and loss of the liquid soaking on the wiping cloth during the movement of the wiping cloth toward the wiping head. This improves the sufficiency, uniformity, and stability of the liquid coating on the surface to be wiped, ensuring a consistent and uniform wiping effect each time. When using the above-mentioned wiping assembly, it can not only effectively control the amount of wiping liquid used, but also avoid the waste and overflow of the wiping liquid, and also avoid the volatilization and loss of the liquid soaking on the wiping cloth, thereby improving the uniformity, stability, and sufficiency of the liquid wiping.

[0050] Furthermore, the connecting distance between each liquid outlet hole and the liquid flow channel is the same, which improves the uniformity of the liquid in the liquid flow channel wetting the outer wiping cloth after overflowing from the liquid outlet hole, and further improves the uniformity of wiping.

[0051] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. 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.
