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 for coating inspection, 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 positioning axis of the cloth placing and collecting system is adjustable and easily disassembled, allowing for quick replacement of the wiping cloth after it is consumed. It can also be adapted to dust-free cloths of different materials and elasticity, improving compatibility with different inspection requirements.
[0025] A wiping head 2 is provided at the end of the wiping block 1 for contacting the product 100 to be wiped through the wiping cloth 5. A first guide bar 91 and a second guide bar 92 are respectively provided in the movement direction of the wiping cloth 5 and between the cloth placing module 61 and the wiping head 2, and between the wiping head 2 and the cloth collecting module 62, so that the wiping cloth 5 is wound around the first guide bar 91 and the second guide bar 92. A first pressure bar 10 and a second pressure bar 11 are respectively provided on the side of the wiping cloth 5 opposite to the first guide bar 91 and the second guide bar 92. The first pressure bar 10 and the second pressure bar 11, each connected to the driving module 12, can move accordingly in the direction close to or away from the first guide bar 91 and the second guide bar 92.
[0026] The wiping block 1 further includes a horizontal plate 101 and a bent plate 102 located at the end of the horizontal plate 101. The wiping head 2 is arranged on the end of the bent plate 102 opposite to the horizontal plate 101. The first guide bar 91 and the second guide bar 92 are both arranged on the side of the wiping block 1 opposite to the wiping head 2.
[0027] The end of the wiping block 1 opposite to the wiping head 2 is connected to a support plate 13, and the first guide bar 91 and the second guide bar 92 are respectively provided on the support plate 13; the first pressure bar 10 and the second pressure bar 11 are each movably mounted on the support plate 13 via at least one set of guide rails 141 and sliders 142;
[0028] The first guide bar 91 is mounted on the support plate 13 via two opposing support blocks 15 and is located above the end of the wiping block 1 facing away from the wiping head 2. A guide shaft 16 is mounted between the two support blocks 15 and below the end of the wiping block 1 facing away from the wiping head 2.
[0029] 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 above-mentioned cloth-laying module 61, cloth-collecting module 62 and guide roller 63 are all mounted on a supporting side plate 7, which is connected to the supporting plate 13. The cloth-laying and cloth-collecting system is generally used in conjunction with a motor, which can reasonably adjust the motor angular velocity under different cloth-laying and cloth-collecting radii, so that the front and rear cloth-collecting wheels and cloth-laying wheels can accurately control the length of the reel;
[0031] The supporting side plate 7 is mounted on a driving module, and is used to drive the supporting side plate to drive the wiping head on the wiping block and the wiping cloth outside it to move 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;
[0032] The angle between the bent plate 102 and the horizontal plate 101 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;
[0033] The wiping block 1 is provided with at least two first stops 81 spaced apart along the moving direction of the wiping cloth 5 and at least two second stops 82 arranged opposite to the first stops 81. The wiping cloth 5 is movably arranged between the first stop 81 and the second stop 82. By reasonably adjusting the positions of the baffles at both ends of the cloth-releasing roller and the cloth-collecting roller and the guide strips at both ends of the guide roller, in conjunction with the first and second stops on the wiping block, the wiping cloth can maintain a stable position during the entire process of retracting, releasing and wiping operations, thereby avoiding the problem that the liquid in the liquid flow channel of the wiping head seeps out from the side and directly drips onto the product due to the deviation or skew of the wiping cloth, as well as the interference and damage to the product during the contact between the wiping block and the product, thereby effectively ensuring the wiping effect.
[0034] The wiping head 2 is a PEEK wiping head. The use of a wiping head with a certain degree of 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 dust-free cloth.
[0035] The wiping head 2 faces a circular arc surface of the product 100 to be wiped.
[0036] Embodiment 2: A wiping assembly for coating detection, comprising: a cloth placing module 61, a cloth collecting module 62 and a wiping block 1, a wiping cloth 5 is wound on the cloth placing module 61, the wiping block 1 and the cloth collecting module 62, and a wiping head 2 is provided at the end of the wiping block 1 for contacting the product 100 to be wiped through the wiping cloth 5, and a first guide bar 91 and a second guide bar 92 are respectively provided in the movement direction of the wiping cloth 5 and between the cloth placing module 61 and the wiping head 2, and between the wiping head 2 and the cloth collecting module 62, so that the wiping cloth 5 is wound on the first guide bar 91 and the second guide bar 92, and a first pressure bar 10 and a second pressure bar 11 are respectively provided on the side of the wiping cloth 5 opposite to the first guide bar 91 and the second guide bar 92, and the first pressure bar 10 and the second pressure bar 11, each of which is connected to the driving module 12, can move in the direction close to or away from the first guide bar 91 and the second guide bar 92 accordingly.
[0037] The first pressure strip 10 and the second pressure strip 11 are both configured as cylindrical elastic strips; the driving module 12 is a cylinder;
[0038] The area of the wiping block 1 near the wiping head 2 is provided with a plurality of liquid outlets 3 that are in contact with the wiping cloth 5. In the direction of movement of the wiping cloth 5, the liquid outlets 3 are located on the side of the wiping head 2 near the cloth placing module 61. The liquid outlets 3 are connected to the liquid flow channel 4 provided in the wiping block 1.
[0039] The wiping head 2 is a rubber wiping head. The use of a wiping head with a certain degree of 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.
[0040] The working principle is:
[0041] Used to detect defects on the coated surface of glass products (such as the glass back panel of electronic products), where the coated surface is the surface to be wiped;
[0042] When in use, the rolled strip of wiping cloth is first mounted on the cloth placing module, and the driving module drives the first pressing strip 10 and the second pressing strip 11 away from the first guide strip 91 and the second guide strip 92, respectively, so as to form a gap for the wiping cloth to pass through between the first pressing strip 10 and the first guide strip 91, and between the second pressing strip 11 and the second guide strip 92;
[0043] Then, one end of the wiping cloth is passed through the first guide strip 91, one side surface of the wiping block, the wiping head, the other side surface of the wiping block and the second guide strip 92 in sequence and then installed on the cloth collecting module. The guide roller 63 can also be used to guide and reverse the wiping cloth.
[0044] Furthermore, the first guide strip 91 that is higher than the wiping head and the guide shaft that is lower than the wiping head can reduce the contact area between the wiping cloth and the wiping head, which not only facilitates the movement of the wiping cloth but also reduces the wear on the wiping cloth.
[0045] After the installation is completed, while the wiping cloth is kept in tension, the driving module drives the first pressure strip 10 and the second pressure strip 11 to move toward the first guide strip 91 and the second guide strip 92 respectively and press the wiping cloth wrapped around the first guide strip 91 and the second guide strip 92, so that when the wiping head drives the wiping cloth to wipe the surface to be wiped, the tensioned state of the wiping cloth in contact with the surface to be wiped is maintained, thereby preventing the wiping cloth from moving relative to the wiping head during the moving wiping process and sticking to the product or causing stacking, resulting in abnormal wiping pressure and damage to the product;
[0046] The wiping cloth can be driven by the cloth collecting module to move from the cloth feeding 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;
[0047] 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;
[0048] Loading the product to be wiped onto a movable carrier with the coated surface of the product to be wiped facing upward;
[0049] 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;
[0050] 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;
[0051] Then, the wiping head and the wiping cloth outside thereof are driven by the wiping block to move horizontally to the other end of the surface to be wiped, thereby achieving uniform and comprehensive wiping of the liquid soaked on the wiping cloth on the surface to be wiped.
[0052] When the above-mentioned coating detection wiping assembly is used, it is convenient to install the wiping cloth, and the tightness of the wiping cloth on the outside of the wiping head can be controlled within a reasonable range during the moving wiping process. It can avoid the wiping cloth being too tight affecting the pressure of the wiping head and compressing the wiping area, and it can also avoid the wiping cloth being too loose causing entanglement, the wiping cloth wrapped around the outside of the wiping head being too large, affecting the wiping liquid penetration effect, and the wiping cloth moving relative to the wiping head during the moving wiping process and sticking to the product or stacking, resulting in abnormal wiping pressure and damage to the product.
[0053] 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.
