Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spraying equipment, in particular to sheet metal electrostatic robot spraying equipment. Background Art

[0002] The automobile manufacturing industry is generally moving towards large-scale, high-quality and low-cost. When painting automobile parts, the traditional manual electrostatic spraying technology can no longer meet the needs of manufacturers due to the high consumption of manpower and materials, lack of cleanliness and environmental protection, and poor spraying quality. Therefore, spraying robots are needed to complete the corresponding work.

[0003] When a traditional electrostatic spray robot is in use, a corresponding nozzle is installed on the robot's mechanical arm and connected to a pipeline. However, when the traditional nozzle equipment is in use, the powder will float in the air after coming out of the nozzle and then come into contact with the parts. Before the powder comes into contact with the parts, the powder will fly in the air, which will result in the powder not being able to completely come into contact with the parts, causing a certain amount of powder waste. In addition, there is a lack of restrictions on the flying of powder, which causes the powder to come into contact with the mechanical arm, thereby causing a certain impact on the mechanical arm.

[0008] As a preferred technical solution of the utility model: an inserting hole is provided on the outer wall of the floating plate, and the inner wall diameter of the inserting hole matches the outer wall diameter of the vertical pole.

[0009] As a preferred technical solution of the utility model: a control panel and a buzzer are arranged on the outer wall of the paint bucket, and the control panel and the buzzer are electrically connected to the contact plate and the trigger plate respectively.

[0010] As a preferred technical solution of the utility model: the outer wall of the protective cover is provided with ventilation holes, and the opening position of the ventilation holes corresponds to the installation position of the blowing pipe.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The sheet metal electrostatic robot spraying equipment has a protective cover arranged on the outer wall of the spray head and an air blow pipe arranged on the outer wall of the protective cover. When the paint powder comes out from the inside of the spray head, the powder will be accelerated again under the action of the air blow pipe, so that the powder can contact the outer wall of the part faster, and under the action of the protective cover, the powder is prevented from flying outward, so that the powder can better contact the outer wall of the part, improve the utilization rate of the powder, and make the powder contact the outer wall of the part faster, thereby improving the spraying efficiency of the equipment.

[0013] 2. The sheet metal electrostatic robot spraying equipment uses the vertical pole and contact plate set inside the paint bucket. As the spraying progresses, the amount of spray powder will decrease, causing the floating plate to slide down. During the sliding of the floating plate, the trigger plate will contact the contact plate to form a connected circuit. At this time, the control board can activate the buzzer to remind the staff to add paint powder, so as to better carry out the spraying operation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] By means of the protective cover 8 arranged on the outer wall of the No. 4 support arm 5, the blowing pipe 9 and the driving fan 11 arranged on the outer wall of the protective cover 8, when the equipment is used for spraying, the powder flies out from the spray head 7. At this time, under the action of the driving fan 11 arranged in the inner cavity of the blowing pipe 9, the powder will be blown forward, so that the powder can still have a certain power after flying out from the inner cavity of the spray head 7, so that the powder can better contact the outer wall of the part.

[0023] In a preferred embodiment, there are two blowing pipes 9 , and the two blowing pipes 9 are respectively installed on the outer walls of both sides of the protective cover 8 .

[0024] By setting the blowing pipe 9 on both sides of the outer wall of the protective cover 8 and the driving fan 11 in the inner cavity of the blowing pipe 9, the driving fan 11 will blow air downward to continuously accelerate the powder coming out of the spray head 7, so that the powder can continue to move forward after coming out of the spray head 7, so as to better fit the outer wall of the part.

[0025] In a preferred embodiment: a controller is installed on the outer wall of the protective cover 8, and the controller is electrically connected to the driving fans 11 in the inner cavities of the blowing pipes 9 on both sides.

[0026] By installing a controller on the outer wall of the protective cover 8, the speed of the driving fan 11 is controlled separately under the action of the controller, so that the driving fan 11 blows the powder forward to prevent the powder from moving backward, causing the powder to be unable to contact the outer wall of the part, thereby improving the utilization rate of the powder.

[0027] In a preferred embodiment, an insertion hole is formed on the outer wall of the floating plate 15 , and the inner wall diameter of the insertion hole matches the outer wall diameter of the vertical rod 13 .

[0028] By setting the floating plate 15 on the outer wall of the vertical pole 13, when the powder is sprayed, the powder will drop, so that the floating plate 15 moves downward along the outer wall of the vertical pole 13, so that the trigger plate 16 on the inner wall of the floating plate 15 contacts the contact plate 14, thereby triggering the connecting circuit, thereby reminding the staff that powder needs to be added.

[0029] In a preferred embodiment, a control panel and a buzzer are disposed on the outer wall of the paint bucket 12 , and the control panel and the buzzer are electrically connected to the contact plate 14 and the trigger plate 16 , respectively.

[0030] By means of the buzzer and control panel arranged on the outer wall of the paint bucket 12, during the descent of the floating plate 15, the trigger plate 16 arranged on the inner wall of the floating plate 15 will also descend along the outer wall of the vertical pole 13. When the floating plate 15 descends to a certain height, the trigger plate 16 will contact the outer wall of the contact plate 14, thereby triggering the connection circuit and activating the buzzer under the action of the control panel to remind the staff.

[0031] In a preferred embodiment, ventilation holes are provided on the outer wall of the protective cover 8 , and the opening positions of the ventilation holes correspond to the installation positions of the blowing pipes 9 .

[0032] Through the ventilation holes opened on the outer wall of the protective cover 8, after the driving fan 11 in the inner cavity of the blowing pipe 9 is started, air will be blown outward from the inner cavity of the protective cover 8, so that the powder sprayed from the spray head 7 is further accelerated, so that the powder contacts the outer wall of the part more quickly, and avoids the powder staying and flying in the air after coming out of the spray head 7, causing the powder to contact the outer wall of the equipment.

[0033] Working principle: During the use of the above-mentioned equipment, the powder is extracted from the inner cavity of the paint bucket 12 through the connecting pipe 17 and the spraying pipe 6, and released outwardly through the spraying head 7. At this time, the driving fan 11 is started by the controller, so that the driving fan 11 blows air into the inner cavity of the protective cover 8, thereby further accelerating the powder coming out of the inner cavity of the spraying head 7, so that the powder contacts the outer wall of the part faster, and the outer wall of the part is better sprayed with the cooperation of the rotating base 1 and the No. 1 support arm 2, the No. 2 support arm 3, the No. 3 support arm 4, and the No. 4 support arm 5. In the process of spraying, the powder height in the inner cavity of the paint bucket 12 will decrease with the progress of spraying. At this time, the floating plate 15 will also decrease with the decrease of the powder height. In the process of the floating plate 15 moving downward, the trigger plate 16 set on the inner wall of the floating plate 15 will contact the contact plate 14 to form a connecting circuit, and activate the buzzer under the action of the control board, so as to remind the staff that they need to add spray powder to the inner cavity of the paint bucket 12 to ensure stable operation of the equipment.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
