Description

Technical Field

[0001] The present application relates to the technical field of roller coating equipment, and in particular to a roller coating device based on a robotic arm. Background Art

[0002] Roller coating uses a roller as a carrier of anti-corrosion paint, and the anti-corrosion paint forms a wet film of a certain thickness on the surface of the roller. Then, the roller contacts the object to be coated during the rotation process to apply the anti-corrosion paint on the surface of the object to be coated. Compared with spraying, roller coating does not splash paint mist, and the coating speed is fast and the coating efficiency is high.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. On the contrary, the embodiments of the present application include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0026] The following describes the roller coating device based on a robotic arm in an embodiment of the present application in conjunction with the accompanying drawings.

[0027] like Figures 1 to 6 As shown, the robot-arm-based roller coating device of an embodiment of the present application may include a vertical plate 1, multiple coating rollers 2, multiple conductive rollers 4, multiple dispersion components 6, multiple transmission components 7 and two support components 8.

[0029] It should be noted that the vertical plate 1 described in this embodiment is installed on a base, and a universal wheel is provided at the bottom of the base to facilitate the movement of the entire roller coating device. In order to improve the stability of the entire device, a counterweight block can be installed on the base.

[0030] Furthermore, the support plate 12 is a U-shaped plate, a support shaft is provided at the center of the coating roller 2, the coating roller 2 is rotatably connected to the support shaft, and the support shaft is threadedly connected to the side wall of the support plate 12 to facilitate disassembly and replacement of the coating roller 2.

[0031] Two groups of first rotating shafts 3 are rotatably connected to the support plate 12 , and each first rotating shaft 3 is provided with a conducting roller 4 . The conducting rollers 4 are respectively arranged above the corresponding coating rollers 2 , and a conveying assembly 9 is provided above the conducting rollers 4 .

[0032] It should be noted that the two groups of first rotating shafts 3 described in this embodiment include two first rotating shafts 3, and a driving motor is provided between the two first rotating shafts 3. The driving motor is a dual-axis motor. One end of the first rotating shaft 3 is connected to the output end of the driving motor, and the other end of the first rotating shaft 3 passes through the side plate of the support plate 12. The first rotating shaft 3 can be driven to rotate by the driving motor.

[0033] Furthermore, the conductive roller 4 is made of a strong water-absorbing material, such as a sponge, so that it can absorb more anti-corrosion paint, and the conveying component 9 can convey the anti-corrosion paint to the conductive roller 4.

[0034] A plurality of transverse plates 13 are provided on the support plate 12, each transverse plate 13 is provided with a reciprocating swing mechanism 5, a plurality of dispersion components 6 are respectively arranged on one side of the corresponding coating roller 2, and the dispersion components 6 are connected to the reciprocating swing mechanism 5, a plurality of transmission components 7 are respectively arranged on both sides of the support plate 12, and the transmission components 7 are respectively connected to the first rotating shaft 3 and the reciprocating swing mechanism 5.

[0035] It should be noted that the dispersion component 6 described in this embodiment can disperse the fibers on the surface of the coating roller 2, so that the anti-corrosion paint can be better absorbed, thereby improving the uniformity of the anti-corrosion paint coating.

[0036] Furthermore, when the driving motor controls the first rotating shaft 3 to rotate, the transmission assembly 7 and the reciprocating swing mechanism 5 cooperate to drive the dispersing assembly 6 to move back and forth, thereby achieving the purpose of dispersing the fibers on the surface of the coating roller 2.

[0037] The two support assemblies 8 are respectively arranged on the support plate 12 one above the other, and the support assembly 8 is disposed between the two coating rollers 2 .

[0038] In the embodiment of the present application, the position of the coating roller 2 can be limited by the support assembly 8, thereby alleviating the impact force of the robot arm 11 on the coating roller, and further improving the uniformity of coating.

[0039] In order to further clarify the above embodiment, in one embodiment of the present application, Figure 5 As shown, the dispersion component 6 includes an arc-shaped plate 60 , a connecting plate 61 and a plurality of needles 62 , wherein the connecting plate 61 is arranged on the side wall of the arc-shaped plate 60 , and the plurality of needles 62 are evenly distributed on the arc-shaped surface of the arc-shaped plate 60 .

[0040] It should be noted that the needles 62 are inserted into the fibers of the coating roller 2, and the arc plate 60 reciprocates along the axis of the coating roller 2 and drives the needles 62 to reciprocate, thereby dispersing the fibers on the coating roller 2 to better absorb the anti-corrosion paint.

[0041] Furthermore, the connecting plate 61 is slidably disposed on the upper surface of the transverse plate 13 to limit the moving direction of the connecting plate 61 , thereby improving the stability of the reciprocating movement of the connecting plate 61 .

[0042] Furthermore, if Figure 4 As shown, the reciprocating swing mechanism 5 includes an incomplete gear 50, a tooth plate 51, a connecting rod 52, a rotating rod 53 and a second rotating shaft 54, wherein the incomplete gear 50 is rotatably set on the cross plate 13, the tooth plate 51 is set on the side wall of the connecting plate 61, and the incomplete gear 50 is meshingly connected with the tooth plate 51, a slide groove 500 is penetrated on the incomplete gear 50, a slide rod 14 is arranged in the slide groove 500, the second rotating shaft 54 ​​is rotatably set on the cross plate 13, the rotating rod 53 is set on the second rotating shaft 54, and the two ends of the connecting rod 52 are respectively hinged to the rotating rod 53 and the slide rod 14.

[0043] It should be noted that the slide rod 14 described in this embodiment can be fixed on the incomplete gear 50 by a nut, and the position of the slide rod 14 in the slide groove 500 is variable, so that the swing amplitude of the incomplete gear 50 can be adjusted as needed.

[0044] In the embodiment of the present application, when the second rotating shaft 54 ​​rotates, it can drive the rotating rod 53 to rotate, and through the cooperation of the connecting rod 52, drive the incomplete gear 50 to swing back and forth, and then drive the toothed plate 51 to move back and forth, and finally realize the reciprocating movement of the driving dispersion component 6.

[0045] In one embodiment of the present application, Figure 3 As shown, the transmission assembly 7 includes a transmission shaft 70, two bevel gears 71, two sprockets 72 and a toothed chain 73, wherein a mounting plate 15 is provided on the side wall of the support plate 12, the transmission shaft 70 is rotatably mounted on the mounting plate 15, the two bevel gears 71 are respectively arranged on the transmission shaft 70 and the first rotating shaft 3, and the two bevel gears 71 are meshedly connected, the two sprockets 72 are respectively arranged on the transmission shaft 70 and the second rotating shaft 54, and the two sprockets 72 are transmission-connected via a toothed chain 73.

[0046] It should be noted that the side wall of the support plate 12 is penetrated by a through groove allowing the tooth chain 73 to pass through, and the tooth chain 73 does not contact the inner wall of the through groove. When the first rotating shaft 3 rotates, the cooperation between the two bevel gears 71 can drive the transmission shaft 70 to rotate, and finally, through the cooperation between the two sprockets 72 and the tooth chain 73, the second rotating shaft 54 ​​is driven to rotate, and finally the tooth plate 51 is driven to reciprocate.

[0047] In one embodiment of the present application, Figure 6 As shown, the support assembly 8 may include a support sleeve 80, a support rod 81, a spring 82 and a roller 83, wherein the support sleeve 80 is arranged on the support plate 12, one end of the support rod 81 is slidably connected to the support sleeve 80, and the other end of the support rod 81 is connected to the roller 83, one end of the support rod 81 is provided with a groove 810, one end of the spring 82 is connected to the bottom of the groove 810, and the other end of the spring 82 is connected to the support sleeve 80.

[0048] It should be noted that when the spring 82 is in a natural state, the roller 83 protrudes from the coating roller 2, that is, the distance between the roller 83 and the coated object is closer. When the robot arm 11 drives the coating roller 2 to move in the direction of the coated object, the roller 83 first contacts the coated object and continuously compresses the spring 82 to deform until the support rod 81 moves to abut against the inner wall of the support sleeve 80. At this time, the coating roller 2 abuts against the coated object, thereby limiting the coating roller 2 and effectively alleviating the impact force of the robot arm 11 on the coating roller 2, thereby ensuring the uniformity of the coating.

[0049] In one embodiment of the present application, Figure 1 As shown, the conveying assembly 9 may include a main pipe 90 and a plurality of branch pipes 91 , wherein the main pipe 90 is disposed above the conductive roller 4 , and the plurality of branch pipes 91 are respectively connected to the main pipe 90 .

[0050] It should be noted that the branch pipe 91 described in this embodiment is arranged at the bottom of the main pipe 90, and the discharge port of the branch pipe 91 is located directly above the conduction roller 4. The main pipe 90 is connected to the anti-corrosion paint bucket through a liquid pump (the anti-corrosion paint bucket can be placed on the base). The anti-corrosion paint inside the anti-corrosion paint bucket can be transported to the main pipe 90 through the liquid pump, and the anti-corrosion paint is transported to the conduction roller 4 through the branch pipe 91, and then the anti-corrosion paint is conducted to the coating roller 2 through the conduction roller 4.

[0051] Specifically, when using the robot arm 11 to apply anti-corrosion paint with a roller, the relevant personnel can control the robot arm 11 to move the support plate 12 towards the direction of the coated object, so that the roller 83 first fits with the coated object, and applies pressure to the roller 83, so that the spring 82 is compressed and hidden in the groove 810, and the end of the support rod 81 facing away from the roller 83 abuts against the inner wall of the support sleeve 80. At this time, the coating roller 2 is in abutment with the coated object.

[0052] Then, the anti-corrosion paint is transported to the inside of the main pipe 90 through a liquid pump, and the anti-corrosion paint is guided to the conductive roller 4 through the branch pipe 91, and the first rotating shaft 3 is controlled to rotate by a motor, and the first rotating shaft 3 drives the conductive roller 4 to rotate. The strong adsorption force of the conductive roller 4 can fully absorb the anti-corrosion paint and make the anti-corrosion paint more evenly distributed. When the conductive roller 4 absorbs the anti-corrosion paint saturated, the coating roller 2 squeezes the conductive roller 4 so that the anti-corrosion paint on the conductive roller 4 falls evenly on the coating roller 2. When the coating roller 2 rolls, the anti-corrosion paint can be evenly coated on the coated object.

[0053] When the first rotating shaft 3 rotates, the cooperation of the two bevel gears 71 can drive the transmission shaft 70 to rotate, and then the cooperation between the sprocket 72 and the tooth chain 73 can drive the second rotating shaft 54 ​​to rotate, and the second rotating shaft 54 ​​drives the rotating rod 53 to rotate, and through the cooperation of the connecting rod 52, it drives the incomplete gear 50 to swing back and forth, and then drives the tooth plate 51 to move back and forth, and uses multiple needles 62 to disperse the fibers on the coating roller 2 to better absorb the anti-corrosion paint, which is conducive to the uniform coating of the anti-corrosion paint.

[0054] In summary, the roller coating device based on the robot arm of the embodiment of the present application enhances the re-adsorption performance of the fibers on the coating roller during the coating process by effectively dispersing the fibers, thereby improving the uniformity of the coating. In addition, the coating roller can be limited by the support assembly, which effectively alleviates the impact between the coating roller and the coated object, further ensuring the improvement of the uniformity of the coating.
