Description

Technical Field

[0001] This utility model relates to the field of spray painting equipment technology, and in particular to a robot-assisted fully automatic furniture spray painting equipment. Background Technology

[0002] Robot-assisted fully automatic furniture painting equipment is a system that uses industrial robot technology for automated spraying. It is mainly used in the furniture industry for painting processes. This equipment can replace manual labor for efficient and precise painting operations and is widely used for surface treatment of furniture made of wood, metal, plastic and other materials.

[0003] Most existing robot-assisted fully automatic furniture painting equipment uses a robotic arm mounted near a conveyor belt. As the conveyor belt transports the furniture, the robotic arm rotates, causing the spray nozzles to move and perform the painting operation.

[0004] However, due to the fixed installation height and limited reach of the robotic arm, when painting large and tall furniture, the spray nozzle may not be able to completely cover the top of the furniture, resulting in uneven painting on the top of the furniture and affecting the quality of the paint job. Utility Model Content

[0005] The technical problem this invention aims to solve is that, due to the fixed installation height and limited reach of the robotic arm, when painting large and tall furniture, the spray nozzle may not be able to completely cover the top of the furniture, resulting in uneven painting on the top of the furniture and affecting the quality of the paint job.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a robot-assisted fully automatic furniture painting equipment, comprising: a robotic arm, which is installed on the ground to drive the movement of nozzles, wherein the nozzles draw out external paint through hoses and pumps and spray it onto the furniture surface; a conveyor belt, which is placed on the ground to carry and transport the furniture, wherein the conveyor belt is driven by a motor in conjunction with a gear chain; and an adjustment device, which is set at the bottom of the robotic arm, wherein the adjustment device drives the robotic arm to move up and down, changing the working height of the robotic arm.

[0007] Preferably, the adjustment device includes: a motor, which is placed on the ground via a base plate, wherein the output end of the motor is fixedly connected to a screw via a coupling; a top plate, which is fixedly connected to the bottom of the robotic arm; and a screw ring, wherein the screw ring is fixedly connected to the top plate via a round rod, and wherein the inner wall of the screw ring is threadedly connected to the surface of the screw.

[0008] The effect achieved by the above components is as follows: By setting up the adjustment device, the motor is first started, which drives the screw to rotate. The screw drives the screw hole ring to move up and down, which in turn drives the top plate to move up and down through the round rod. This, in turn, drives the robotic arm to move up and down, thereby achieving height adjustment of the robotic arm. This reduces the situation where, when the robotic arm is painting large and tall furniture, the nozzle cannot completely cover the top of the furniture due to insufficient height, resulting in uneven painting of the top of the furniture and affecting the quality of the painting. This improves the efficiency of painting furniture and the operational flexibility of the robotic arm.

[0009] Preferably, the adjusting device further includes a telescopic rod, wherein one end of the telescopic rod is fixedly connected to the bottom plate and the other end is fixedly connected to the top plate.

[0010] The effect achieved by the above components is that by setting the telescopic rod, the telescopic rod can limit the top plate, reducing the shaking or rotation of the top plate during the process of being driven by the screw.

[0011] Preferably, the adjustment device further includes: a support plate, wherein a plurality of support plates are uniformly fixed to the side of the top plate away from the robotic arm.

[0012] The effect achieved by the above components is that by setting up a support plate, the support plate can support and reinforce the top plate, reducing the possibility of tilting at the edge of the top plate away from the round rod.

[0013] Preferably, the adjusting device further includes a pad, wherein the pad is fixed to the side of the top plate near the round rod, and the position of the pad corresponds to that of the screw.

[0014] The effect achieved by the above components is that by setting up a pad, the pad can separate the screw from the top plate, reducing the collision and wear between the screw and the top plate.

[0015] Preferably, it further includes: a protective component, the protective component comprising: a protective cylinder that encloses the entire adjusting device, wherein the base plate is fixedly connected to the inner wall of the protective cylinder; and a mounting ring that is fixedly connected to the protective cylinder, wherein the mounting ring is placed on the ground and fixed by bolts.

[0016] The effects achieved by the above components are as follows: By setting up protective components, the adjustment device is first placed on the ground through the protective sleeve and mounting ring. Then, the bolts are screwed into the mounting ring and the ground to fix the mounting ring, thus completing the installation and fixation of the robotic arm. At the same time, the protective sleeve encloses the entire adjustment device and intercepts external paint and objects, thereby protecting the adjustment device and reducing the possibility of damage to the components of the adjustment device caused by paint corrosion or collisions with objects. This improves the safety and service life of the adjustment device.

[0017] Preferably, the surface of the protective cylinder is fixedly connected with a plurality of reinforcing rods, and the plurality of reinforcing rods are arranged at equal intervals.

[0018] The effect achieved by the above-mentioned components is that the strength of the protective cylinder can be increased by setting the reinforcing rod, and the deformation of the protective cylinder after being subjected to force can be reduced.

[0019] Preferably, a rubber pad is fixedly connected to the side of the protective cylinder away from the mounting ring.

[0020] The effect achieved by the above components is that by setting rubber pads, the rubber pads can fill the gap between the protective cylinder and the robotic arm, while separating the two and reducing the contact wear between them.

[0021] The beneficial effects of this utility model are:

[0022] By setting an adjustment device, the placement height of the robotic arm can be freely adjusted, reducing the situation where the nozzle cannot fully cover the top of the furniture due to insufficient height when the robotic arm is painting large and tall furniture. This would result in uneven painting of the top of the furniture and affect the quality of the painting, thus improving the efficiency of furniture painting and the operational flexibility of the robotic arm.

[0031] Figure 1-4 The illustrated robotic-assisted fully automatic furniture painting equipment includes: a robotic arm 1, mounted on the ground to drive a nozzle 2, wherein the nozzle 2 draws out external paint through a hose and a pump and sprays it onto the furniture surface; a conveyor belt 3, placed on the ground to carry and transport the furniture, wherein the conveyor belt 3 is driven by a motor in conjunction with a gear chain; and an adjusting device 4, located at the bottom of the robotic arm 1, wherein the adjusting device 4 drives the robotic arm 1 to move up and down, changing the working height of the robotic arm 1.

[0032] Figure 2 and Figure 3 The adjustment device 4 shown includes: a motor 42, which is placed on the ground via a base plate 41, wherein the output end of the motor 42 is fixedly connected to a screw 43 via a coupling; a top plate 46, which is fixedly connected to the bottom of the robotic arm 1; and a screw ring 44, which is fixedly connected to the top plate 46 via a round rod 45, wherein the inner wall of the screw ring 44 is threadedly connected to the surface of the screw 43. By setting the adjustment device 4, the motor 42 is first started, causing the motor 42 to drive the screw 43 to rotate, causing the screw 43 to drive the screw ring 44 to move up and down, causing the screw ring 44 to drive the top plate 46 to move up and down via the round rod 45, and causing the top plate 46 to drive the robotic arm 1 to move up and down, thereby achieving height adjustment of the robotic arm 1. This reduces the situation where the robotic arm 1, when painting large and tall furniture, cannot completely cover the top of the furniture due to insufficient height, resulting in uneven painting of the top of the furniture and affecting the quality of the furniture painting. This improves the efficiency of furniture painting and the operational flexibility of the robotic arm 1.

[0033] Figure 2 and Figure 3The adjustment device 4 shown also includes a telescopic rod 49, one end of which is fixedly connected to the base plate 41 and the other end of which is fixedly connected to the top plate 46. By setting the telescopic rod 49, the telescopic rod 49 can limit the top plate 46, reducing the shaking or rotation of the top plate 46 during the process of being driven by the screw 43. The adjustment device 4 also includes a support plate 47, wherein multiple support plates 47 are evenly fixedly connected to the side of the top plate 46 away from the robotic arm 1. By setting the support plate 47, the support plate 47 can support and reinforce the top plate 46, reducing the tilting of the edge of the top plate 46 away from the round rod 45.

[0034] Figure 2 and Figure 3 The adjustment device 4 shown also includes a pad 48, which is fixed to the top plate 46 on the side near the round rod 45. The pad 48 corresponds to the position of the screw 43. By setting the pad 48, the pad 48 can separate the screw 43 from the top plate 46, reducing the collision and wear between the screw 43 and the top plate 46.

[0035] Figure 4 The device also includes a protective assembly 5, which comprises a protective cylinder 52 that encloses the entire adjustment device 4, wherein the base plate 41 is fixedly connected to the inner wall of the protective cylinder 52; and a mounting ring 51 that is fixedly connected to the protective cylinder 52. The mounting ring 51 is placed on the ground and fixed with bolts. By setting up the protective assembly 5, the adjustment device 4 is first placed on the ground through the protective cylinder 52 and the mounting ring 51. Then, bolts are screwed into the mounting ring 51 and the ground surface is used to fix the mounting ring 51, thus completing the installation and fixation of the robotic arm 1. At the same time, the protective cylinder 52 encloses the entire adjustment device 4 and intercepts external paint and objects, thereby protecting the adjustment device 4 and reducing the risk of damage to the components of the adjustment device 4 caused by paint corrosion or collisions with objects. This improves the safety and service life of the adjustment device 4.

[0036] Figure 4 Multiple reinforcing rods 53 are fixedly connected to the surface of the protective cylinder 52 shown. The multiple reinforcing rods 53 are arranged at equal intervals. By setting the reinforcing rods 53, the strength of the protective cylinder 52 can be increased and the deformation of the protective cylinder 52 after being subjected to force can be reduced. A rubber pad 54 is fixedly connected to the side of the protective cylinder 52 away from the mounting ring 51. By setting the rubber pad 54, the rubber pad 54 can fill the gap between the protective cylinder 52 and the robotic arm 1, and at the same time separate the two, reducing the large contact wear between them.

[0037] Working principle: First, the adjustment device 4 is placed on the ground through the protective cylinder 52 and the mounting ring 51. Then, the bolts are screwed into the mounting ring 51 and the ground is used to fix the mounting ring 51, thus completing the installation and fixation of the robotic arm 1. At the same time, the protective cylinder 52 encloses the entire adjustment device 4 and intercepts external paint and objects, thereby protecting the adjustment device 4. When it is necessary to adjust the height of the robotic arm 1, the motor 42 is started, which drives the screw 43 to rotate. The screw 43 drives the screw hole ring 44 to move up and down, which in turn drives the top plate 46 to move up and down through the round rod 45. The top plate 46 then drives the robotic arm 1 to move up and down, thereby achieving the height adjustment of the robotic arm 1.

[0038] At this time, the motor, in conjunction with the gear chain, drives the conveyor belt 3 to move, so that the conveyor belt 3 transports the furniture. During the transportation process, the robotic arm 1 operates and drives the nozzle 2 to move. During the movement of the nozzle 2, the paint is drawn in and sprayed onto the surface of the furniture using a hose and a pump, thus achieving the painting operation of the furniture.

[0039] The painting robotic arm 1 can be a Haizhi Robotics HZP1900-6, Yaskawa HP20D, or Borunte BRH10-940. As a conventional technical means, this application does not elaborate on its working principle.

[0040] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
