An automatically adjustable spraying robot and its adjustment method

Abstract

This invention relates to the field of spraying robot technology and discloses an automatically adjustable spraying robot and its adjustment method. An extrusion tube is fixedly connected to the side of the support platform, and an extrusion cylinder is fixedly connected to the side of the extrusion tube away from the support platform. An extrusion motor is fixedly connected to the side of the extrusion cylinder away from the extrusion tube, and an extrusion screw is fixedly connected to the output shaft of the extrusion motor. The extrusion screw is located inside the extrusion cylinder. This invention, by incorporating a storage mechanism, an adjustment mechanism, a discharge mechanism, and a spraying robot, facilitates the adjustment of the spraying volume. When the total amount of raw material in the storage mechanism decreases, a sliding plate in the storage mechanism moves downwards. At this time, the sliding plate drives a traction rope to move. When the traction rope moves, it causes a movable pulley to drive a connecting rod to move upwards. When the connecting rod moves upwards, it causes a change in the electronic speed of the sliding rheostat, thereby changing the rotational speed of the extrusion motor and ensuring a constant total amount of material sprayed from the spraying robot.

Description

Technical Field

[0001] This invention relates to the field of spraying robot technology, and more specifically to an automatically adjustable spraying robot and its adjustment method. Background Technology

[0002] A painting robot, also known as a spray painting robot, is an industrial robot that can automatically spray paint or apply other coatings. A painting robot mainly consists of a robot body, a computer, and a corresponding control system. Hydraulically driven painting robots also include a hydraulic oil source. They mostly adopt a 5 or 6 degree of freedom articulated structure, with a large range of motion in the arm, and can perform complex trajectory movements. More advanced painting robots use a flexible wrist that can bend and rotate in all directions, and its movements are similar to those of a human wrist. It can easily reach into the interior of a workpiece through a small hole to spray its inner surface.

[0003] When the spraying robot is in use, the spraying material is stored in the material tank. When the total amount of material in the material tank changes, the speed at which the material enters the extrusion mechanism will change due to the water pressure. Therefore, the amount of spraying when the spraying robot is spraying will change, resulting in uneven spraying. Moreover, if the material is stored in the material tank for a long time, the material will settle, which will affect the spraying effect. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatically adjustable spraying robot and its adjustment method. The technical problem to be solved by the present invention is that the spraying volume fluctuates and the spraying material settles when the spraying robot performs spraying.

[0005] An automatically adjustable spraying robot and its adjustment method are disclosed, comprising a spraying robot and further comprising:

[0006] Support platform: The top of the support platform is fixedly connected to the bottom of the painting robot;

[0007] Discharge mechanism: One side of the discharge mechanism is fixedly connected to the side of the support platform;

[0008] Storage mechanism: The bottom end of the storage mechanism and the top end of the discharge mechanism are fixed away from the support platform;

[0009] Adjustment mechanism: The side of the adjustment mechanism is fixedly connected to the side of the storage mechanism;

[0010] Mixing mechanism: The side of the mixing mechanism and the bottom end of the storage mechanism away from the side of the adjusting mechanism are fixedly connected;

[0011] Wherein: an extrusion tube is fixedly connected to the side of the support platform, an extrusion cylinder is fixedly connected to the side of the extrusion tube away from the support platform, an extrusion motor is fixedly connected to the side of the extrusion cylinder away from the extrusion tube, an extrusion screw is fixedly connected to the output shaft of the extrusion motor, and the extrusion screw is located inside the extrusion cylinder.

[0012] Furthermore, a holding box is fixedly connected to the top of the extrusion cylinder, and a sliding plate is movably connected inside the holding box. A traction rope is fixedly connected to one side of the top of the sliding plate. A fixed pulley is movably connected to the bottom of the middle part of the holding box, and the bottom end of the fixed pulley is fixedly connected to one side of the top of the holding box. A movable pulley is movably connected to the bottom end of the traction rope away from the sliding plate. A connecting box is fixedly connected to the side of the holding box, and a connecting plate is fixedly connected to the top of the connecting box away from the holding box. A connecting rope is fixedly connected to the bottom end of the connecting plate, and the other side of the connecting rope is fixedly connected to the side of the traction rope. A connecting rod is fixedly connected to the bottom end of the movable pulley, and a sliding rheostat is fixedly connected to the bottom end of the connecting rod. The bottom end of the sliding rheostat is fixedly connected to the bottom end inside the connecting box. The sliding rheostat is connected to the extrusion motor. When the connecting rod moves upward, the resistance value of the sliding rheostat decreases, thereby increasing the speed of the extrusion motor and ensuring that the extrusion volume of the discharge mechanism remains consistent.

[0013] Furthermore, counterweights are fixedly connected to both sides of the movable pulley, and a limiting plate is fixedly connected to the side of the counterweight away from the movable pulley. Slide grooves are opened on both sides inside the connecting box, and the limiting plate is located in the slide groove of the connecting box. The weight of the counterweight is one-third of the weight of the sliding plate, and the weight of the two counterweights is two-thirds of the weight of the sliding plate, so that the sliding plate can drive the counterweight to move. When the raw material enters the holding box, the sliding plate will not be unable to be lifted due to excessive weight.

[0014] Furthermore, a second switch is fixedly connected to the top of the connecting box slide, and limit blocks are fixedly connected to the four corners of the top of the inside of the holding box. A first switch is fixedly connected to the bottom of the limit blocks. The top of the connecting box near the inside of the holding box is set as an inclined surface, and the top of the connecting box near the side of the holding box is set as an inclined surface. This ensures that when the position of the movable pulley changes and the position and angle of the traction rope change, it will not contact the connecting box and affect the movement.

[0015] Furthermore, the mixing mechanism includes a mixing tank, a sealing cover fixedly connected to the top of the mixing tank, a rotating motor fixedly connected to the top of the sealing cover, a pressure boosting valve fixedly connected to the bottom of the mixing tank, a feed pipe fixedly connected to the bottom of the pressure boosting valve, and the other side of the feed pipe fixedly connected to the bottom of the side of the holding tank. A motor housing is fixedly connected to the side of the extrusion motor away from the extrusion pipe, and the extrusion motor is located inside the motor housing. Motor housings are provided on the outer sides of the motors, and these outer motor housings must be protected to prevent the spraying robot from spilling spraying materials onto the motors during spraying operations, thus avoiding leakage.

[0016] Furthermore, a rotating shaft is fixedly connected to the bottom end of the rotating motor, a rotating gear is fixedly connected to the top end of the side of the rotating shaft, a transmission gear is driven to the outer edge of the rotating gear, and an external gear is driven to the outer edge of the transmission gear away from the first blade. All gears mesh with each other. A first blade is fixedly connected to the side of the rotating shaft, a rotating rod is fixedly connected to the bottom end of the external gear, a second blade is fixedly connected to the side of the rotating rod, and a connecting shaft is movably connected to the top end of the transmission gear. The top end of the connecting shaft is fixedly connected to the bottom end of the sealing cover. There are four rotating rods, and the second blade is located between two first blades, so that the second blade and the first blade can evenly mix the raw materials.

[0017] Furthermore, the outer side of the external gear has a sliding groove, and an upper limit ring is movably connected in the sliding groove of the external gear. The outer side of the upper limit ring is fixedly connected to the inside of the mixing box. The bottom end of the rotating rod is fixedly connected to a connecting ring, and the outer side of the connecting ring has a sliding groove. A lower limit ring is movably connected in the sliding groove of the connecting ring. The outer side of the lower limit ring is fixedly connected to the inside of the mixing box.

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. This invention, by incorporating a storage mechanism, an adjustment mechanism, a discharge mechanism, and a spraying robot, facilitates the adjustment of the spraying volume. When the total amount of raw material in the storage mechanism decreases, the sliding plate in the storage mechanism moves downward. At this time, the sliding plate drives the traction rope to move. When the traction rope moves, the movable pulley drives the connecting rod to move upward. When the connecting rod moves upward, it causes the electronic of the sliding rheostat to change, thereby changing the speed of the extrusion motor, thus ensuring that the total amount sprayed from the spraying robot remains constant.

[0020] 2. The present invention, by having a rotating shaft, a rotating gear, an upper limit ring, and a second blade, helps to maintain a relatively uniform coating material. The rotation of the rotating shaft drives the first blade to rotate, and when the rotating shaft rotates, it drives the transmission gear to rotate through the rotating gear, thereby causing the external gear to drive the rotating rod to rotate. The rotating rod drives the second blade to move, thereby rotating the material in the mixing box in two directions to make it evenly mixed.

[0021] 3. The present invention, by providing an external gear, an upper limit ring, a connecting ring, and a lower limit ring, is beneficial to the stability of the rotating rod when it moves. When the external gear rotates, the upper limit ring restricts its movement position, and the lower limit ring restricts the movement distance of the connecting ring, thereby enabling the rotating rod between the connecting ring and the external gear to rotate stably.

[0022] 4. The present invention uses a mixing mechanism to mix raw materials. After the raw materials are mixed evenly in the mixing mechanism, they are injected into the holding box, so that the extruded raw materials are all in a uniform state. Moreover, the raw materials in the holding box can be replenished in the mixing mechanism after replenishment, so that the newly added raw materials will not be directly extruded.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatically adjustable spraying robot and its adjustment method involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-2 This invention provides an automatically adjustable spraying robot and its adjustment method, comprising a spraying robot 1, and further comprising:

[0035] Support platform 2: The top of support platform 2 is fixedly connected to the bottom of spraying robot 1;

[0036] Discharge mechanism 3: One side of the discharge mechanism 3 is fixedly connected to the side of the support platform 2;

[0037] Storage mechanism 4: The bottom end of storage mechanism 4 and the top end of discharge mechanism 3 are fixed on the side away from support platform 2;

[0038] Adjustment mechanism 5: The side of adjustment mechanism 5 is fixedly connected to the side of storage mechanism 4;

[0039] Mixing mechanism 6: The side of mixing mechanism 6 and the bottom end of storage mechanism 4 away from the side of adjustment mechanism 5 are fixedly connected;

[0040] Wherein: an extrusion tube 301 is fixedly connected to the side of the support platform 2, an extrusion cylinder 302 is fixedly connected to the side of the extrusion tube 301 away from the support platform 2, an extrusion motor 303 is fixedly connected to the side of the extrusion cylinder 302 away from the extrusion tube 301, an extrusion screw 304 is fixedly connected to the output shaft of the extrusion motor 303, and the extrusion screw 304 is located inside the extrusion cylinder 302.

[0041] Reference Figure 3-7 A holding box 401 is fixedly connected to the top of the extrusion cylinder 302. A sliding plate 404 is movably connected inside the holding box 401. A traction rope 403 is fixedly connected to one side of the top of the sliding plate 404. A fixed pulley 402 is movably connected to the bottom of the middle part of the holding box 401. The bottom end of the fixed pulley 402 is fixedly connected to one side of the top of the holding box 401. A movable pulley 504 is movably connected to the bottom end of the traction rope 403 away from the sliding plate 404. A connecting box 501 is fixedly connected to the side of the holding box 401. A connecting plate 502 is fixedly connected to the top of the connecting box 501 on the side away from the holding box 401. A connecting rope 503 is fixedly connected to the bottom end of the connecting plate 502. The other side of rope 503 is fixedly connected to the side of traction rope 403. A connecting rod 507 is fixedly connected to the bottom of movable pulley 504. A sliding rheostat 508 is fixedly connected to the bottom of connecting rod 507. The bottom of sliding rheostat 508 is fixedly connected to the bottom of the inside of connecting box 501. When the material in the holding box 401 decreases and the sliding plate 404 descends, the traction rope 403 will move. When the traction rope 403 moves to the side of the holding box 401, the movable pulley 504 moves upward. At this time, the sliding rheostat 508 will change its resistance value. The use of movable pulley can reduce the movement of connecting rod 507 and can cooperate with the smaller sliding rheostat 508.

[0042] Reference Figure 3-7 The movable pulley 504 is fixedly connected to two sides of a counterweight 506. A limit plate 505 is fixedly connected to the side of the counterweight 506 away from the movable pulley 504. The connecting box 501 has sliding grooves on both sides inside. The limit plate 505 is located in the sliding groove of the connecting box 501. The weight of the counterweight 506 is one-third of the weight of the sliding plate 404. The limit plate 505 slides in the sliding groove of the connecting box 501, thereby restricting the movement of the counterweight 506 and ensuring that the counterweight 506 moves stably. This prevents the movable pulley 504 from tilting or sliding when it moves up and down, thus preventing it from driving the connecting rod 507 to move.

[0043] Reference Figure 3-7A second switch 509 is fixedly connected to the top of the sliding groove of the connecting box 501. Limiting blocks 405 are fixedly connected to the four corners of the top of the inner part of the holding box 401. A first switch 406 is fixedly connected to the bottom of the limiting block 405. The top of the connecting box 501 near the inner side of the holding box 401 is set as an inclined surface. The movement distance of the sliding plate 404 is limited by the limiting block 405 to prevent it from derailing. The top of the connecting box 501 is equipped with a second switch 509 so that the material in the holding box 401 can be replenished in time when it is empty. The first switch 406 makes the holding box 401 automatically stop after it is full of material.

[0044] Reference Figure 8 and Figure 9 The mixing mechanism 6 includes a mixing tank 603, a sealing cover 604 fixedly connected to the top of the mixing tank 603, a rotating motor 605 fixedly connected to the top of the sealing cover 604, a pressure boosting valve 602 fixedly connected to the bottom of the mixing tank 603, a feed pipe 601 fixedly connected to the bottom of the pressure boosting valve 602, and the other side of the feed pipe 601 fixedly connected to the bottom of the side of the holding tank 401. A motor housing 305 is fixedly connected to the side of the extrusion motor 303 away from the extrusion pipe 301. The extrusion motor 303 is located inside the motor housing 305, and a motor housing 305 is provided on the outside of the motor. By providing a pressure boosting valve 602 at the bottom of the mixing tank 603, it can be ensured that all the raw materials in the mixing tank 603 can enter the holding tank 401 from the bottom of the holding tank 401, and there will be no spillage of raw materials.

[0045] Reference Figure 8 and Figure 9 A rotating shaft 606 is fixedly connected to the bottom end of a rotating motor 605. A rotating gear 607 is fixedly connected to the top end of the side of the rotating shaft 606. A transmission gear 609 is driven to the outer edge of the rotating gear 607. An external gear 611 is driven to the outer edge of the transmission gear 609 away from the first blade 608. The gears are all meshed with each other. A first blade 608 is fixedly connected to the side of the rotating shaft 606. A rotating rod 613 is fixedly connected to the bottom end of the external gear 611. A second blade 614 is fixedly connected to the side of the rotating rod 613. A connecting shaft 610 is movably connected to the top end of the transmission gear 609. The top end of the connecting shaft 610 is fixedly connected to the bottom end of the sealing cover 604. The rotating gear 607 drives the transmission gear 609 to rotate, and the transmission gear 609 drives the external gear 611 to rotate, so that the external gear 611 rotates in the opposite direction to the rotating shaft 606, making the raw materials in the mixing box 603 more evenly mixed.

[0046] Reference Figure 8 and Figure 9The outer gear 611 has a sliding groove on its outer side, and an upper limit ring 612 is movably connected in the sliding groove of the outer gear 611. The outer side of the upper limit ring 612 is fixedly connected to the inside of the mixing box 603. A connecting ring 615 is fixedly connected to the bottom end of the rotating rod 613. A sliding groove is opened on the outer side of the connecting ring 615, and a lower limit ring 616 is movably connected in the sliding groove of the connecting ring 615. The outer side of the lower limit ring 616 is fixedly connected to the inside of the mixing box 603. The top and bottom ends of the rotating rod 613 are connected to the outer gear 611 and the connecting ring 615 respectively, thereby ensuring the stability of the rotating rod 613 when it moves. The outer gear 611 and the connecting ring 615 are restricted in their rotation position by the upper limit ring 612 and the lower limit ring 616.

[0047] An adjustment method for an automatically adjustable spraying robot includes the following steps:

[0048] S1. The container 401 is filled with spraying material. The spraying material in the container 401 enters the extrusion cylinder 302. The extrusion motor 303 is started. The extrusion motor 303 starts and drives the extrusion screw 304 to rotate, thereby extruding the material from the extrusion tube 301 and spraying it through the spraying robot 1.

[0049] S2. As the amount of raw material in the holding box 401 decreases, the sliding plate 404 descends. The descent of the sliding plate 404 causes the traction rope 403 to rotate. The rotation of the traction rope 403 causes the movable pulley 504 to move upward. The upward movement of the movable pulley 504 causes the connecting rod 507 to move upward. When the connecting rod 507 moves upward, the resistance value of the sliding rheostat 508 decreases, increasing the speed of the extrusion motor 303, thereby ensuring that the raw material extruded from the extrusion tube 301 is more uniform.

[0050] S3. The upward movement of the movable pulley 504 drives the counterweight block 506 and the limit plate 505 to move upward. The upward movement of the limit plate 505 will trigger the second switch 509. After the second switch 509 is triggered, the pressure valve 602 is activated. The raw materials in the mixing box 603 are replenished into the holding box 401 through the feed pipe 601, causing the sliding plate 404 to move upward. The upward movement of the sliding plate 404 triggers the first switch 406 to complete the replenishment.

[0051] S4. When the raw materials in the mixing box 603 are mixed, the rotating motor 605 is started. The rotating motor 605 drives the rotating shaft 606 to rotate. The rotating shaft 606 drives the first blade 608 to rotate. The rotation of the rotating shaft 606 drives the external gear 611 to rotate through the transmission gear 609. The rotation of the external gear 611 drives the rotating rod 613 to move. The movement of the rotating rod 613 drives the second blade 614 to move, thereby making the raw materials in the mixing box 603 evenly mixed.

[0052] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.

When the connecting rod (507) moves upward, the resistance value of the sliding rheostat (508) decreases, increasing the speed of the extrusion motor (303), thereby ensuring that the raw material extruded by the extrusion tube (301) is relatively uniform. S3. The upward movement of the movable pulley (504) drives the counterweight (506) and the limit plate (505) to move upward. The upward movement of the limit plate (505) will trigger the second switch (509). After the second switch (509) is triggered, the pressure valve (602) is activated. The raw materials in the mixing box (603) are replenished into the holding box (401) through the feed pipe (601), causing the sliding plate (404) to move upward. The upward movement of the sliding plate (404) triggers the first switch (406) to complete the replenishment. S4. When the raw materials in the mixing box (603) are mixed, the rotating motor (605) is started. The rotating motor (605) drives the rotating shaft (606) to rotate. The rotating shaft (606) drives the first blade (608) to rotate. The rotating shaft (606) drives the external gear (611) to rotate through the transmission gear (609). The external gear (611) drives the rotating rod (613) to move. The rotating rod (613) moves and drives the second blade (614) to move, so that the raw materials in the mixing box (603) can be mixed evenly.
