[0035] For the convenience of understanding the utility model, the utility model will be described more fully below with reference to the relevant drawings. The drawings show the typical embodiments of the utility model. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive. It should be understood that the embodiments of the utility model and the specific features in the embodiments are detailed descriptions of the technical solutions of the application, and not limitations of the technical solutions of the application, and the technical features in the embodiments of the utility model and the embodiments can be combined with each other without conflict.

[0036] Before introducing the embodiment, the product to be wiped is introduced first. As shown in Figures 1-3 The product is a substantially rectangular cover body, including a bottom and a peripheral sidewall. The outer surface of the bottom is a rectangular appearance surface, and the rectangular corners are arc-shaped. The peripheral sidewall of the product encloses a very shallow groove. The inner surface of the sidewall is an inkjet surface 101, and the inkjet surface can also be the entire recessed surface of the product. The outer surface of the sidewall is divided into two parts, a circular arc 102 and a body 103. The circular arc 102 is connected with the peripheral plane of the bottom and is curved in a circular arc shape. The body 103 is a vertical surface connected with the periphery of the circular arc 102. Because the circular arc 102 and the body 103 are generally stained with ink, the circular arc 102 and the body 103 need to be wiped. The wiping overflow ink device of the embodiment is used to wipe the circular arc 102 and the body 103.

[0037] With reference to Figure 4 The wiping overflow ink device of the present embodiment includes a wiping cloth feeding mechanism 4, a wiping head linear driving mechanism 5, a rotating clamping structure 6, a product linear driving mechanism 7, and at least one wiping head 3.

[0038] The wiping head 3 provides a wiping surface for wiping the product 1, which includes the body wiping surface 11 and the arc wiping surface 12 arranged in layers. The wiping cloth feeding mechanism 4 is used to collect and release the wiping cloth 41, which covers the wiping surface. The rotating clamping structure 6 is used to horizontally clamp the product 1 and drive the product 1 to rotate around the Z-axis, so as to replace the specific section of the body 103 or the arc 102 of the product 1 that needs to be wiped. The wiping head linear driving mechanism 5 is used to drive the wiping head 3 to move along the Y-axis, so that the wiping surface is directed towards the rotating clamping structure 6 and is pressed against the body 103 or the arc 102 of the product 1 during wiping, so that the wiping cloth 41 is in contact with the body 103 or the arc 102 of the product 1. The product linear driving mechanism 7 is arranged along the Y-axis and is connected to the rotating clamping structure 6 to drive the product 1 to move along the X-axis, so as to realize wiping of the body 103 or the arc 102 of the product 1 by the wiping cloth 41.

[0039] The body wiping surface 11 and the arc wiping surface 12 can be used to wipe the body 103 and the arc 102 simultaneously, for example, by allowing the body wiping surface 11 and the arc wiping surface 12 to be in contact with the body 103 and the arc 102 of the product at the same time. However, experiments show that the wiping effect of the body 103 is not good when wiping simultaneously, which may be due to the fact that the wiping cloth 41 at the joint of the body wiping surface 11 and the arc wiping surface 12 does not completely fit the wiping surface, so that the joint of the body 103 and the arc 102 of the product is not wiped sufficiently. In addition, the body 103 and the arc 102 are not suitable for wiping with the same material, because the arc 102 has a tolerance. If a hard material is used to wipe the arc 102, the arc 102 will not be wiped clean, and if a soft material is used, the arc 102 will be deformed and will wipe the inkjet surface 101. Therefore, preferably, the body wiping surface 11 and the arc wiping surface 12 are made of different materials. Figure 6The wiping head 3 in the embodiment comprises a wiping head body 31 with two layers of different hardness, the side of the layer with relatively higher hardness in the wiping head body 31 facing the rotating clamping structure 6 is a vertical plane as the body wiping surface 11, and the side of the layer with relatively lower hardness in the wiping head body 31 facing the rotating clamping structure 6 is a curved surface matching the arc of the product 1 as the arc wiping surface 12. Because of the different hardness, the pressing degree required in wiping is also different, so from this perspective, the body 103 and the arc 102 are not suitable for synchronous wiping. Therefore, in the embodiment, the wiping of the body wiping surface 11 on the body 103 and the wiping of the arc wiping surface 12 on the arc 102 are carried out separately. Specifically, the width of the body wiping surface 11 is greater than the width of the body of the product 1, and a lifting platform 2 that can be lifted along the Z-axis is arranged, and the wiping head linear driving mechanism 5 and the wiping cloth feeding mechanism 4 are installed on the lifting platform 2. The lifting platform 2 is used to change the height of the wiping head 3 in the Z-axis direction, adjust the height of the body wiping surface 11 and the arc wiping surface 12, so as to select one of the body wiping surface 11 and the arc wiping surface 12 for wiping the product 1. When wiping the body of the product 1, the area of the body wiping surface 11 away from the arc wiping surface 12 is in contact with the body of the product 1, and the area of the body wiping surface 11 adjacent to the arc wiping surface 12 is misaligned with the body of the product 1 upward and downward, so that the arc wiping surface 12 cannot contact the product, and the edge of the arc wiping surface 12 away from the body wiping surface 11 is chamfered 13 to avoid the appearance surface of the bottom of the product when the arc wiping surface 12 wipes the product. In addition, when wiping the arc, the area of the body wiping surface 11 adjacent to the arc wiping surface 12 can be in contact with the product, and the material of the body wiping surface 11 is relatively hard, which can affect the contact of the arc wiping surface 12 with the arc, so the area of the body wiping surface 11 adjacent to the arc wiping surface 12 can be changed from a vertical surface to a flat surface or an inclined surface, so as to avoid limiting the arc wiping surface 12 from continuing to approach the arc of the product when wiping the arc of the product because of the contact of the body wiping surface 11 with the product.

[0040] The various structures will be described in more detail below.

[0041] Reference Figures 4-5The lifting platform 2 comprises a lifting cylinder 24, a carrier table 21, a Z-direction guide shaft 23 and a Z-direction guide sleeve 22.

[0042] Reference Figure 7 The wiping head 3 is a plurality of wiping heads arranged in a row along the X-axis direction. In this embodiment, the wiping surface 11 is above and the arc wiping surface 12 is below, but they can also be reversed, and the product can also be placed upside down accordingly. Each wiping head 3 is provided with a wiping cloth 41, the wiping head linear driving mechanism 5 is connected to each wiping head 3 to drive each wiping head 3 to move synchronously, and the product linear driving mechanism 7 is connected to each rotating clamping structure 6 to drive each product to move synchronously.

[0043] The wiping head 3 specifically comprises a wiping head main body 31, a wiping head seat body 32, a Y-axis linear sliding rail 33 and an elastic member 34. The wiping head main body 31 is divided into two layers, which are made of different materials. The upper layer is made of Al6061, which is harder, and the lower layer is made of polyurethane, which is softer. The wiping head seat body 32 is assembled by a plurality of plates. The side of each wiping head seat body 32 away from the product 1 is connected to the wiping head linear driving mechanism 5 to move along the Y-axis under the driving of the wiping head linear driving mechanism 5. The Y-axis linear sliding rail 33 extends along the Y-axis and is fixed to the top of the wiping head seat body 32. The bottom of the wiping head main body 31 is in sliding cooperation with the Y-axis linear sliding rail 33. The side of the top of the wiping head seat body 32 away from the product 1 is provided with a vertical baffle 321, and the elastic member 34 can deform along the Y-axis and be clamped between the side of the wiping head main body 31 opposite to the wiping surface and the baffle 321 at the top of the wiping head seat body 32. The elastic member 34 can be a spring. In this way, the wiping head main body 31 can move along the Y-axis, and the wiping force can be adjusted to prevent over-wiping of the product 1.

[0044] Reference Figure 5 , 8The linear driving mechanism 5 of the wiping head comprises a screw rod Y-axis motor 50, a screw rod nut 51, a Y-axis connecting plate 52, a Y-axis connecting plate 53, and a row of Y-axis sliding rails 54 extending along the Y-axis direction.

A row of wiping heads 3 are installed on the row of Y-axis sliding rails 54 through the wiping head seat bodies 32, and the bottom of each wiping head seat body 32 is in sliding fit with the corresponding Y-axis sliding rail 54. The screw rod Y-axis motor 50 is installed on the bottom of the top plate 211, the screw rod nut 51 is installed on the screw rod of the screw rod Y-axis motor 50, and the Y-axis connecting plate 52 extending vertically is installed on the screw rod nut 51. An avoiding slot is formed on the top plate 211 for the movement of the connecting block 52 along the Y-axis direction, and the avoiding slot is located between the two Y-axis sliding rails 54 in the middle. The Y-axis connecting plate 53 extends along the X-axis direction and is located on the side of the wiping head seat bodies 32 of the row of wiping heads 3 away from the product 1. The wiping head seat bodies 32 of the row of wiping heads 3 are also connected with the Y-axis connecting plate 53, and the Y-axis connecting plate 52 is connected with the Y-axis connecting plate 53 after passing through the avoiding slot, so that the row of wiping heads 3 can be synchronously moved along the Y-axis.

[0045] Reference Figure 4 , 7 , 9, the wiping cloth feeding mechanism 4 comprises a wiping cloth 41, a winding flywheel 42, a winding motor 43 driving the winding flywheel 42 to rotate to realize winding of the wiping cloth 41, a unwinding flywheel 44, and a unwinding motor 45 driving the unwinding flywheel 44 to rotate to realize unwinding of the wiping cloth 41. The wiping cloth 41 is specifically a metal cloth, and of course can also be any other cloth suitable for wiping, which is not limited.

[0046] The winding flywheel 42 and the unwinding flywheel 45 are located above and below the linear driving mechanism 5 of the wiping head respectively. Specifically, the winding flywheel 42 is rotatably installed on a vertical plate on the top of the top plate 211, and the unwinding flywheel 45 is rotatably installed on a vertical plate between the bottom plate 212 and the top plate 211. One end of the wiping cloth 41 is wound on the winding flywheel 43, and the other end is wound on the unwinding flywheel 45 after turning at the wiping surface.

[0047] In order to ensure the good adhesion of the wiping cloth 41 to the wiping surface of the wiping head 3, preferably, the wiping cloth feeding mechanism 4 of the present embodiment further comprises a wiping cloth lower pressing cylinder 46 and a wiping cloth upper lifting cylinder 47 extending along the X-axis direction, the wiping cloth lower pressing cylinder 46 and the winding flywheel 42 are located above the wiping head linear driving mechanism 5 and the wiping head 3, and the wiping cloth upper lifting cylinder 47 and the unwinding flywheel 45 are located below the wiping head linear driving mechanism 5. The wiping cloth lower pressing cylinder 46 and the wiping cloth upper lifting cylinder 47 are both close to the wiping head 3, the wiping cloth lower pressing cylinder 46 is used to press the wiping cloth 41 close to the top of the wiping head 3 and then tilt at a small angle (for example, the angle between the wiping cloth 41 and the top of the wiping head 3 is less than 30°) to transition to the wiping surface, and the wiping cloth upper lifting cylinder 47 is used to lift the wiping cloth 41 close to the bottom of the wiping head 3 and then tilt at a small angle (for example, the angle between the wiping cloth 41 and the bottom of the wiping head 3 is less than 30°) to transition to the wiping surface. After being pressed by the wiping cloth upper lifting cylinder 47, the wiping cloth 41 is turned to be perpendicular, extends to be below the top plate 211, is turned to be close to horizontal by the cylinder 48, and then is wound around the unwinding flywheel 45.

[0048] With reference to the above Figure 7 Since the wiping heads 3 in the present embodiment are multiple and arranged along the X-axis direction, the number of the rotary clamping structures 6 is also multiple and arranged along the X-axis direction. The rotary clamping structure 6 comprises a rotary motor 61, a rotary suction member 62 for horizontally placing the product 1 at the top, a product pressing head 63 for clamping the product 1 together with the rotary suction member 62 up and down, a rotary lower pressing cylinder 64, and a swing arm 65. The rotary suction member 62 is in the shape of a circular shaft, the bottom of which is connected with the rotary motor 61 to rotate around the Z-axis direction with the rotary motor 61, and the top of which is provided with vacuum holes for suction of the product 1, the vacuum holes are also connected with a vacuum device through pipelines. The product pressing head 63 is connected with the swing arm 65 to rotate around the Z-axis direction to ensure that the product pressing head 63 rotates together with the product 1. The swing arm 65 is connected with the rotary lower pressing cylinder 64 to rotate to the upper side of the product 1 under the drive of the rotary lower pressing cylinder 64 and then press the product 1 to ensure that the product pressing head 63 rotates together with the product 1.

[0049] More specifically, the product pressing head 63 comprises a connecting shaft and a pressing shaft arranged coaxially, the upper end of the connecting shaft is connected with the swing arm 65 perpendicularly, the lower end of the connecting shaft is connected with the upper end of the pressing shaft through a bearing, and the end face of the lower end of the pressing shaft is used to contact with the product. When the product 1 needs to be installed, first place the inkjet face 101 of the product upward on the top of the rotary suction member 62, open the vacuum suction column to suck the product 1, then rotate the rotary pressing cylinder 64 to rotate the swing arm 65 to the upper side of the product 1, so that the product pressing head 63 is also above the product 1. Then rotate the rotary pressing cylinder 64 to lower the swing arm 65 until the pressing shaft of the product pressing head 63 presses the product 1. During the wiping process, when the product 1 needs to be rotated to switch the wiping section, because the connecting shaft and the pressing shaft are connected through a bearing, the pressing shaft will rotate with the product, while the connecting shaft is fixed, so that the product 1 can be pressed all the time.

[0050] With reference to the above Figure 7 , the product linear driving mechanism 7 comprises a module for X-axis movement, a servo motor 71 for driving the module, and a row of T-shaped connecting plates 72, the T-shaped connecting plates 72 comprise a first vertical plate and a second vertical plate, the centers of the first vertical plate and the second vertical plate are connected perpendicularly, a row of rotary clamping structures 6 are fixed to the side of the first vertical plate facing the wiping head 3, the center line of the other side of the first vertical plate is connected with the second vertical plate, and the second vertical plate is connected with the top of the module mover. The linear driving mechanism in the present application is not limited, as long as it can realize linear movement.

[0051] The wiping process of the present embodiment is to divide the contour of the product 1 into sections: each straight edge corresponds to a section, and each corner is divided into multiple sections. As shown in Figure 3 , 1a represents a corner, and 1b represents a straight edge. The corner 1a needs to be divided into multiple sections for wiping, and each straight edge 1b can be used as a section for wiping. After the rotary clamping structure 6 clamps the product 1, the following steps are executed:

[0052] Body wiping step: adjust the height of the wiping head 3 to the first height, move the wiping head linear driving mechanism 5 along the Y-axis direction to make the wiping cloth 41 in pre-pressing contact with the product 1 body, and move the product linear driving mechanism 7 with the rotary clamping structure 6 along the X-axis direction to reciprocate to wipe a specific section, and rotate the product 1 by the rotary clamping structure 6 to select the next section for wiping after each section is wiped until all sections are wiped;

[0053] Body corner wiping step: adjust the height of the wiping head 3 to a second height, move the wiping head linear drive mechanism 5 along the Y-axis direction to make the wiping cloth 41 in pre-press contact with the product 1 arc, and move the product linear drive mechanism 7 along the X-axis direction with the rotating clamping structure 6 to wipe a specific section, and rotate the product 1 through the rotating clamping structure 6 to select the next section to be wiped after wiping each section until all sections are wiped.

[0054] It should be noted that the body wiping step and the body corner wiping step can be exchanged in order.

[0055] Reference Figure 10 For example, in a specific embodiment, the product corner is divided into three sections for wiping, and the process is as follows:

[0056] ① The product is automatically fed to the rotating clamping structure 6 for clamping;

[0057] ② The wiping head 3 moves forward by the forward rotation of the Y-axis screw motor 50, so that the metal cloth on the body wiping surface 11 is in pre-press contact with the product body, as shown in state a in FIG. 6. Figure 10 Because the width of the body wiping surface 11 is greater than the width of the product body, the height of the wiping head 3 can be adjusted to control the non-contact between the arc wiping surface 12 and the product 1 at this time. The product linear drive mechanism 7 moves the rotating clamping structure 6 and the product 1 left and right, until the product body wiping is completed, the Y-axis screw motor 50 is reversed, and the metal cloth is separated from the product 1;

[0058] ③ The rotating motor 61 rotates by an angle, so that the product 1 body corner part is in contact with the metal cloth, the Y-axis screw motor 50 is forward rotated, the product body corner is in pre-press with the metal cloth, the product linear drive mechanism 7 moves the rotating clamping structure 6 and the product 1 left and right, and after wiping is completed, the Y-axis screw motor 50 is reversed, and the metal cloth is separated from the product 1;

[0059] ④ Repeat step ③ three times, and the product body corner wiping is completed;

[0060] ⑤ Repeat steps ② and ④ three times again, and the product body wiping is completed;

[0061] ⑥ The wiping head top lifting cylinder 24 is reversed, the wiping head 3 is lowered, and the product arc is in pre-press with the metal cloth on the arc wiping surface 12, as shown in state b in FIG. 6. Figure 10
