Description

Technical Field

[0001] The present invention relates to the field of industrial robots, and particularly to an ink jet printer. Background Art

[0002] An ink jet printer is a non-contact ink jet marking system controlled by a single-chip microcomputer. It applies a certain pressure to the ink in the system by controlling an internal gear pump or supplying compressed gas from outside the machine, so that the ink is ejected through a nozzle with a pore diameter of dozens of micrometers; and the continuous ink line ejected is split into ink droplets with the same frequency, equal size and certain spacing by a crystal oscillation signal applied above the nozzle. Then, the ink droplets are respectively charged when passing through the charging electrode, and the amount of charge carried by them is controlled by the central processing unit CPU; then, the actual amount of charge and phase of the ink droplets are detected by the detection electrode; finally, the charged ink droplets are deflected in the deflection electric field formed by the deflection electrode, ejected from the nozzle, and respectively hit different positions on the surface of the product to form various required characters, patterns and other markings;

[0003] For example, the Chinese invention patent with the publication number: 202221058146.8 provides a quick-drying ink jet printer for an automated platform. This quick-drying ink jet printer for an automated platform includes a printer body and an automated platform body. A limiting mechanism is provided on the printer body. The limiting mechanism includes a first installation groove and a pulley. The first installation grooves are symmetrically opened on the side surface of the printer body. The pulley is rotatably installed in the first installation groove through a rotating rod. A limiting chute is opened on the surface of the automated platform body;

[0004] By studying the above-mentioned quick-drying ink jet printer for an automated platform, it is found that this patent can quickly dry the ink after jetting, but cannot clean the used nozzle in time, which is very likely to block the nozzle and affect the next use;

[0005] Therefore, we urgently need to invent an ink jet printer that can not only flush the inside of the printer, but also clean the outside of the printer, avoiding the problem of nozzle blockage, and also realizing automation, improving work efficiency and reducing labor costs. Summary of the Invention

[0006] In view of the above problems, the present invention provides an ink jet coding machine. By setting up a cleaning nozzle mechanism, a brake pad cleaning mechanism, and a soaking nozzle mechanism, functions such as cleaning nozzles, cleaning brake pads, and soaking nozzles are integrated. When the nozzle is not used for a long time, the ink inside the nozzle will dry out. When the nozzle is used again, the nozzle will be blocked. Therefore, after the nozzle is used, the cleaning nozzle mechanism needs to be started to clean the inside of the nozzle; in order to prevent dust on the brake pads during the painting process on the brake pads, the brake pad cleaning mechanism is used to remove dust on the surface to prevent the painting effect from weakening; finally, the outer surface of the nozzle will be contaminated by the splashed paint during the painting process. After the spraying work is completed, the soaking nozzle mechanism is started to clean the outer surface of the nozzle.

[0007] The technical solution used in the present invention is: an ink jet coding machine includes: a cleaning nozzle mechanism, a brake pad cleaning mechanism, and a soaking nozzle mechanism;

[0008] The cleaning nozzle mechanism is installed in the middle of the gantry on the left side of the equipment. A water bucket, an ink storage bucket, and an air storage bucket are fixed on the top triangular plate of the gantry and are located above the cleaning nozzle mechanism. Each of the water bucket, the ink storage bucket, and the air storage bucket has a connecting pipe connected to the nozzle. The brake pad cleaning mechanism is located below the cleaning nozzle mechanism and above the conveyor belt. The start switch is fixed on the connecting bracket of the nozzle. The sponge block part of the soaking nozzle mechanism is fixedly installed on the small gantry on the right side of the cleaning brush. The nozzle can be soaked in the storage bucket of the soaking nozzle mechanism. When the nozzle is not used for a long time, the ink inside the nozzle will dry out. When the nozzle is used again, the nozzle will be blocked. Therefore, after the nozzle is used, the cleaning nozzle mechanism needs to be started to clean the inside of the nozzle; in order to prevent dust on the brake pads during the painting process on the brake pads, the brake pad cleaning mechanism is used to remove dust on the surface to prevent the painting effect from weakening; finally, the outer surface of the nozzle will be contaminated by the splashed paint during the painting process. After the spraying work is completed, the soaking nozzle mechanism is started to clean the outer surface of the nozzle to avoid nozzle blockage.

[0009] Further, the cleaning nozzle mechanism includes: motor A, gear A, gear B, circular plate A, cam, rack A, and gear C;

[0010] The motor A is fixedly installed on the long plate on the upper part of the circular plate in the middle of the gantry on the left side of the equipment. The gear A is fixed on the shaft of the motor A. The gear B meshes with the gear A and is fixed on the cylinder below the circular plate A. The circular plate A is located below the water bucket, the ink storage bucket, and the air storage bucket. The cam is rotationally connected to the motor fixed on the circular plate A. Each group consists of a rack A and a gear C, with a total of three groups, which are respectively fixed on the water bucket, the ink storage bucket, and the air storage bucket. The gear C meshes with the rack A.

[0011] Further, the cleaning brake pad mechanism includes: an electric cylinder, a rack B, a gear D, a cleaning brush, and a start switch;

[0012] The electric cylinder is fixedly installed on the lower surface of the circular plate at the middle part of the left gantry. The cleaning brush is connected to the extending end of the cylinder body of the electric cylinder through a bracket. A rack B is fixedly installed on the bracket above the cleaning brush. The gear D is rotatably installed on the long shaft of the single-side arm and is connected to the wheel on the start switch through a belt. The start switch is fixedly installed on the upper surface of the nozzle sliding bracket.

[0013] Further, the cleaning brush is made of cylindrical nylon filaments, which are wear-resistant and corrosion-resistant.

[0014] Further, the soaking nozzle mechanism includes: a lead screw A, a lead screw B, a storage bucket, a collection bucket, a rod A, a rack C, a water bucket, a circular plate B, a rod B, a circular ring plate, a motor B, a lead screw C, and a sponge block;

[0015] The lead screw A is fixedly installed at the tops of the two support rods. The lead screw B is rotatably installed on the bracket rotatably connected to the lead screw A. The storage bucket is fixed to the bottom of the slider rotatably connected to the lead screw B through two rods. The collection bucket is placed on the ground, outside the conveyor belt. The rod A is fixed inside the collection bucket. The rack C is fixedly installed on the rod extending from the storage bucket and is placed horizontally. The water bucket is placed opposite the collection bucket, outside the conveyor belt, and is supported by a support frame. The circular plate B is fixedly connected to the rod B.

[0016] Further, when the storage bucket moves above the collection bucket, it moves downward driven by the lead screw B. Since the circular plate B presses the rod A, the rod A lifts the circular plate B, so that the sewage inside the storage bucket flows into the collection bucket.

[0017] Further, the UV lamp at the rear of the equipment can quickly dry the ink after inkjet printing.

[0018] Since the present invention adopts the above technical solutions, the present invention has the following advantages:

[0019] 1) The cleaning nozzle mechanism is provided in this equipment, which can wash the inside of the inkjet printer, without disassembling and opening specific components and then manually cleaning, reducing costs and saving water resources;

[0020] 2) The cleaning brake pad mechanism of this device can clean the dust on the surface of the parts to be inkjet printed, preventing the weakening of the painting effect and improving the inkjet printing efficiency of the equipment;

[0021] 3) Inevitably, the inkjet process will contaminate the surface of the nozzle with the coating. The immersion nozzle mechanism of this device can clean the outside of the nozzle, realizing automation, improving work efficiency and reducing labor costs. Brief Description of the Drawings

Detailed Embodiment

[0027] Next, through embodiments and in conjunction with the drawings, the technical solutions of the present invention will be further specifically described. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0028] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0029] Embodiment, as Figure 1-8As shown, an ink jet coding machine, characterized in that it comprises: a cleaning nozzle mechanism 1, a brake pad cleaning mechanism 2 and a soaking nozzle mechanism 3;

[0030] The cleaning nozzle mechanism 1 is installed in the middle of the gantry on the left side of the equipment. A water bucket, an ink storage bucket and an air storage bucket are fixed on the top triangular plate of the gantry and are located above the cleaning nozzle mechanism 1. Each of the water bucket, the ink storage bucket and the air storage bucket has a connecting pipe connected to the nozzle. The brake pad cleaning mechanism 2 is located below the cleaning nozzle mechanism 1 and above the conveyor belt. The start switch 205 is fixed on the connecting bracket of the nozzle. The sponge block part of the soaking nozzle mechanism 3 is fixedly installed on the small gantry on the right side of the cleaning brush 204. The nozzle can be soaked in the storage bucket 303 of the soaking nozzle mechanism 3. When the nozzle is not used for a long time, the ink inside the nozzle will dry out. When the nozzle is used again, the nozzle will be blocked. Therefore, after the nozzle is used up, the cleaning nozzle mechanism 1 needs to be started to clean the inside of the nozzle; in order to prevent dust on the brake pad during the spraying process on the brake pad, the brake pad cleaning mechanism 2 is used to remove the surface dust to prevent the spraying effect from weakening; finally, the spraying process will contaminate the outer surface of the nozzle with the splashed paint. After the spraying work is completed, the soaking nozzle mechanism 3 is started to clean the outer surface of the nozzle.

[0031] In an alternative embodiment of the present invention, as Figure 3-4 shown, the cleaning nozzle mechanism 1 comprises: a motor A101, a gear A102, a gear B103, a circular plate A104, a cam 105, a rack A106 and a gear C107;

[0032] The motor A101 is fixedly installed on the long plate on the upper part of the circular plate in the middle of the left gantry of the equipment. The gear A102 is fixed on the shaft of the motor A101. The gear B103 meshes with the gear A102 and is fixed on the cylinder below the circular plate A104. The circular plate A104 is located below the water bucket, the ink storage bucket and the air storage bucket. The cam 105 is rotationally connected to the motor fixed on the circular plate A104. Each group consists of a rack A106 and a gear C107, with a total of three groups, which are respectively fixed on the water bucket, the ink storage bucket and the air storage bucket. The gear C107 meshes with the rack A106;

[0033] When the nozzle is not used for a long time, the ink inside the nozzle will dry out. When the nozzle is used again, it will clog the nozzle. Therefore, after using the nozzle, the nozzle needs to be cleaned immediately. The motor A101 drives the gear A102 to rotate, which in turn drives the gear B103 to rotate, thereby driving the circular plate A104 to rotate, and then driving the cam 105 to move. When the cam 105 rotates to the position below the corresponding barrel, the motor on the side of the cam 105 drives the cam 105 to rotate, so that the cam 105 pushes the rack A106 to move, which in turn drives the gear C107 to rotate, thereby opening the switch of the corresponding barrel. When the cam 105 rotates back to its original position in reverse, the rack A106 returns to its original position through the spring, which in turn causes the gear C107 to rotate in reverse, and then closes the switch. The order of cleaning the nozzle is as follows: first, open the switch of the ink storage barrel to supply ink to the nozzle for work. After the work is completed, open the water bucket switch, rinse the inside of the nozzle with clean water through the water bucket, and then open the air storage barrel. The air is blown into the inside of the nozzle to dry the water stains.

[0034] In an alternative embodiment of the present invention, as Figure 5 shown, the brake pad cleaning mechanism 2 includes: an electric cylinder 201, a rack B202, a gear D203, a cleaning brush 204, and a start switch 205;

[0035] The electric cylinder 201 is fixedly installed on the lower surface of the circular plate at the middle part of the left gantry. The cleaning brush 204 is connected to the extended end of the cylinder body of the electric cylinder 201 through a bracket. The rack B202 is fixedly installed on the bracket above the cleaning brush 204. The gear D203 is rotatably installed on the long shaft of the single-side arm and is connected to the wheel on the start switch 205 through a belt. The start switch 205 is fixedly installed on the upper surface of the nozzle sliding bracket;

[0036] In order to prevent dust on the brake pads during the painting process of the brake pads, which may cause the painting effect to weaken; the cleaning brush 204 is rotatably installed on the rack. The upper end surface of the rack is fixedly connected to the telescopic rod end of the electric cylinder 201. One end of the electric cylinder 201 is fixedly installed on another rack. When a brake pad moves to the position below the cleaning brush 204 along the conveyor belt, the electric cylinder 201 expands and contracts to drive the cleaning brush 204 to descend. When the cleaning brush 204 contacts the brake pad, as the brake pad moves, the cleaning brush 204 will rotate slightly to clean the brake pad. After the cleaning is completed, the cleaning brush 204 rises to drive the rack B202 to rise, which in turn drives the gear D203 to rotate, thereby turning on the start switch 205, and then the nozzle starts to work to paint the brake pads.

[0037] In an alternative embodiment of the present invention, as Figure 6-8As shown in the figure, the soaking nozzle mechanism 3 includes: lead screw A301, lead screw B302, storage barrel 303, collection barrel 304, rod A305, rack C306, water bucket 307, circular plate B308, rod B309, ring plate 310, motor B311, lead screw C312 and sponge block 313;

[0038] The lead screw A301 is fixedly installed at the top of the two support rods. The lead screw B302 is rotatably installed on the bracket rotatably connected to the lead screw A301. The storage barrel 303 is fixed to the bottom of the slider rotatably connected to the lead screw B302 through two rods. The collection barrel 304 is placed on the ground, outside the conveyor belt. The rod A305 is fixed inside the collection barrel 304. The rack C306 is fixedly installed on the rod extending from the storage barrel 303 and is placed horizontally. The water bucket 307 is placed opposite the collection barrel 304, outside the conveyor belt, and is supported by a support frame. The circular plate B308 is fixedly connected to the rod B309. The rod B309 is slidably installed in the hole of the ring plate 310. The ring plate 310 is fixedly installed inside the storage barrel 303. The motor B311 is fixedly installed on the long bracket of the lower gantry beside the cleaning brush 204. The lead screw C312 is rotatably installed on the long bracket equipped with the motor B311 through the motor B311. The sponge block 313 is rotatably installed on the lead screw C312 through a threaded hole;

[0039] Drive the lead screw B302 to move left and right through the lead screw A301, and drive the storage barrel 303 to move up and down through the lead screw B302, so that the storage barrel 303 can move freely within the area, facilitating the movement of the storage barrel 303 under the nozzle and immersing the nozzle inside the storage barrel 303; after immersion, drive the lead screw B302 to move through the lead screw A301, so that the storage barrel 303 moves above the rod A305, and then drive the storage barrel 303 to descend through the lead screw B302, so that the circular plate B308 presses the rod A305. Since the circular plate B308 is fixedly connected to the rod B309, and the rod B309 is slidably installed in the hole of the circular ring plate 310, and the circular ring plate 310 is fixedly installed inside the storage barrel 303, due to the circular plate B308 pressing the rod A305, the rod A305 lifts the circular plate B308, so that the sewage inside the storage barrel 303 flows into the collection barrel 304; drive the lead screw B302 and the storage barrel 303 to move through the lead screw A301. When the storage barrel 303 drives the rack C306 to move below the clean water barrel 307, when the rack C306 meshes with the gear of the switch below the clean water barrel 307, the switch of the clean water barrel 307 is opened, and the water inside the clean water barrel 307 flows into the storage barrel 303 to wash the residual sewage inside the storage barrel 303, and then repeat the above operation to pour the sewage into the collection barrel 304 through the storage barrel 303 to ensure the cleanliness inside the storage barrel 303; after the nozzle is soaked and rinsed by water flow, drive the lead screw C312 to rotate through the motor B311, thereby driving the slider to move, and then driving the sponge block 313 to move under the nozzle, and wipe the area under the nozzle through the sponge block 313.
