Description

Technical Field

[0001] The invention belongs to the field of spraying technology, and in particular relates to a street lamp pole spraying device and a spraying method. Background Art

[0002] 3D spraying is widely used in the field of automobile painting. Its principle is to use a 3D scanning camera to obtain the three-dimensional image information of the automobile frame to be sprayed, and then control the conveying mechanism to move the automobile frame to be sprayed to the spraying robot. The spraying robot adjusts its position in real time according to the three-dimensional image information obtained by the 3D scanning camera to form a corresponding spraying trajectory to complete the spraying of the automobile frame. When spraying street light poles, most of them are currently sprayed by manual spraying, because street light poles are large in size and can be more than 10 meters long. When spraying, the entire periphery of the pole needs to be sprayed, and the periphery of the pole cannot be blocked. The pole needs to be suspended horizontally during spraying. At present, the 3D spraying equipment for spraying automobile frames cannot be directly applied to the spraying of street light poles. It is necessary to design a powder spraying equipment that can be used for street light poles to improve the efficiency of street light pole painting. Summary of the invention

[0005] Furthermore, one side of the negative pressure mechanism is connected to a cyclone separator through a connecting pipe, and the cyclone separator is connected to the rear end of the suction pipe. The cyclone separator is used to intercept powder with a mass greater than dust, so that powder and dust with a mass less than dust enter the negative pressure mechanism.

[0006] Furthermore, the bottom of the cyclone separator is connected to a fluidizing box, which is used to accommodate and fluidize the spray powder. The fluidizing box is connected to an upper powder spraying mechanism, multiple side powder spraying mechanisms, and a lower powder spraying mechanism. When the cyclone separator is working, the powder retained in the cyclone separator with a mass greater than that of dust is discharged into the fluidizing box.

[0007] Furthermore, the negative pressure mechanism includes a cylinder, a filter screen, and an induced draft fan. The filter screen is arranged in the cylinder, and the induced draft fan is arranged above the filter screen. The bottom of the cylinder is connected to the top of a recovery trolley. The top of the recovery trolley is provided with a feed port, which is connected to the bottom of the cylinder and is used to collect powder entering the cylinder.

[0008] Furthermore, lifting platforms are provided on both sides of the spraying room for lifting and lowering workers.

[0009] Furthermore, two pairs of track wheels are provided at the bottom of the recycling trolley, and the two pairs of track wheels are respectively arranged above the two tracks. The tracks include a horizontal section and an inclined section connected to each other.

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the implementation modes of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] The present application embodiment provides a street lamp pole spraying device, such as Figure 1-Figure 7 As shown, it includes a spraying room 1, a negative pressure mechanism 2, etc.

[0035] Specifically, first openings 101 are provided at both ends of the spraying room 1, and the lamp pole can enter and exit from the first openings 101. A strip groove 102 is provided on the top of the spraying room 1 along the length direction, which runs through both ends of the spraying room 1 and is used to accommodate a storage chain for hanging the lamp pole. An air suction port 103 is provided at the bottom of the spraying room 1. The bottom of the air suction port 103 is connected to a closed shell 104, and the outer side of the closed shell 104 is connected to the front end of an air suction pipe 105. An upper powder spraying mechanism 106, multiple side powder spraying mechanisms 107, and a lower powder spraying mechanism 108 are provided on both sides of the spraying room 1 from top to bottom, and the upper powder spraying mechanism 106, multiple side powder spraying mechanisms 107, and the lower powder spraying mechanism 108 are all arranged to move in the vertical direction and the width direction of the spraying room 1. Specifically, 4 vertical reciprocating machines can be provided. 11 drives two upper powder spraying mechanisms 106 and two lower powder spraying mechanisms 108 to move in the vertical direction, and four horizontal reciprocators 12 are set to drive the two upper powder spraying mechanisms 106 and the two lower powder spraying mechanisms 108 to move in the width direction of the spraying room 1. For multiple side powder spraying mechanisms 107, multiple horizontal reciprocators 12 can be set to control a single side powder spraying mechanism respectively, and then the multiple horizontal reciprocators 12 on the same side are connected to a vertical reciprocator 11, and the vertical reciprocator 11 drives the multiple horizontal reciprocators 12 and the multiple side powder spraying mechanisms 107 on the same side to move in the vertical direction at the same time; the negative pressure mechanism 2 is connected to the rear end of the suction pipe 105, and is used to generate negative pressure in the spraying room 1 through the suction pipe 105 to gather the powder in the spraying room 1.

[0036] During actual use, the lamp pole is first lifted horizontally by the accumulation chain, and the accumulation chain is controlled to drive the lamp pole from a first opening 101 into the spray room 1, and the lamp pole is moved at a uniform speed along the length direction of the spray room, and then the contour information of the lamp pole entering the spray room 1 is obtained in real time by the laser profile measuring instrument, and the upper powder spraying mechanism 106, multiple side powder spraying mechanisms 107, and the lower powder spraying mechanism 108 are controlled to move in real time and spray powder based on the contour information to form a spraying trajectory that matches the contour information of the lamp pole; when spraying powder, the negative pressure mechanism 2 is controlled to open to absorb and gather the powder that is not adhered to the surface of the lamp pole in the spray room 1, and the powder can be separated by a separation device and used for powder spraying again later.

[0037] For details, see Figure 1 There are lifting platforms 109 on both sides of the spraying room 1. The lifting platforms 109 can be used to drive workers to move up and down, so that workers can spray the unpainted parts of the lamp pole. Figure 6 One side of the negative pressure mechanism 2 is connected to a cyclone separator 3 through a connecting pipe, and the cyclone separator 3 is connected to the rear end of the suction pipe 105. The cyclone separator 3 is used to intercept powder with a mass greater than that of dust, that is, to intercept powder with a relatively large particle size, so that powder with a mass less than that of dust and dust enter the negative pressure mechanism 2, thereby achieving the purpose of dust removal, so that the powder intercepted by the cyclone separator 3 can be directly used for powder spraying again.

[0038] For details, see Figure 6 The bottom of the cyclone separator 3 is connected to a fluidizing box 301, which is used to accommodate and fluidize the spray powder. The fluidizing box 301 is connected to the powder inlet end of the upper powder spraying mechanism 106, the powder inlet ends of multiple side powder spraying mechanisms 107, and the powder inlet end of the lower powder spraying mechanism 108, and is used to provide spray powder. When the cyclone separator 3 is working, the powder trapped in the cyclone separator 3 with a mass greater than that of dust is discharged into the fluidizing box 301.

[0039] For details, see Figure 6 , Figure 7 The negative pressure mechanism 2 includes a cylinder 201, a filter 202, and an induced draft fan 203. The filter 202 is arranged in the cylinder 201, and the induced draft fan 203 is arranged above the filter 202. The bottom of the cylinder 201 is connected to the top of a recycling cart 4. The top of the recycling cart 4 is provided with a feed port, which is connected to the bottom of the cylinder 201. After the dust and powder with a mass less than or equal to the dust are sucked into the cylinder 201, they will be blocked by the filter and fall into the recycling cart 4 below. The air sucked by the induced draft fan 203 will be discharged through the filter 202. The dust and powder in the recycling cart 4 can be sent to the recycling plant for secondary recycling.

[0040] After the equipment has been running for a certain period of time, the powder and dust in the recycling cart 4 need to be poured out in time after being filled up, so that it can be used again later. However, it is labor-intensive to take out the recycling cart 4, pour out the materials, and finally put the recycling cart 4 back. In addition, the recycling cart 4 needs to be connected to the cylinder 201 by screws or buckles, and it takes time to align the connection between the recycling cart 4 and the bottom of the cylinder 201. Figure 8-Figure 11 The bottom of the recycling trolley 4 is provided with two pairs of track wheels 401, and the two pairs of track wheels 401 are respectively arranged above the two tracks 5. The track 5 includes a horizontal section 501 and an inclined section 502 connected to each other. When the top of the recycling trolley 4 is aligned with the bottom of the cylinder 201, the recycling trolley 4 is above the horizontal section 501, and the end of the inclined section 502 away from the horizontal section 501 is inclined upward. The end of the inclined section 502 away from the horizontal section 501 is provided with a traction mechanism 6, and the traction rope 601 of the traction mechanism 6 is connected to the recycling trolley 4. A guide column 402 is provided at one end of the two sides of the recycling trolley 4 close to the traction mechanism 6, and a guide plate 7 is symmetrically provided on the outer side of the inclined section 502. A guide groove 701 matching the guide column 402 is provided on the inner side of the guide plate 7. Fig.12 , Fig.13When the guide post 402 enters the guide groove 701 and reaches the end of the guide groove 701, the end of the recycling trolley 4 away from the guide post 402 rotates to an angle less than 90 degrees with the vertical plane. At this time, the powder in the recycling trolley 4 will be poured out. In order to completely pour out the powder in the recycling trolley 4, the traction mechanism 6 can be controlled to pull the recycling trolley 4 to make a small reciprocating motion, so that the guide post 402 on the recycling trolley 4 collides with the end of the guide groove 701, thereby causing the recycling trolley 4 to shake and shake off the powder adhered to the inner wall of the trolley. After pouring out the powder in the recycling trolley 4, the traction mechanism 6 is controlled to release the traction rope 601, and the recycling trolley 4 will slide downward to the horizontal section of the track 5 due to its own gravity. Subsequently, the recycling trolley 4 only needs to be pushed along the track 5 to the bottom of the cylinder 201 to align with it and connect with the cylinder 201, which can effectively improve the installation efficiency of the recycling trolley 4 and the cylinder 201.

[0041] For details, see Figure 8 A stopper 8 is provided at one end of the horizontal section 501 away from the inclined section 502. When the top of the recovery trolley 4 is aligned with the bottom of the cylinder 201, the recovery trolley 4 abuts against the stopper 8. Through this arrangement, the difficulty of aligning the recovery trolley 4 with the cylinder 201 can be further reduced, thereby improving the efficiency of installing the recovery trolley 4 back to the bottom of the cylinder 201.

[0042] For details, see Fig.10 , Fig.11 The traction mechanism 6 includes a rotating shaft 602, and retractable wheels 604 are symmetrically arranged on both sides of the rotating shaft 602. The traction rope 601 is wound around the retractable wheels 604. The rotating shaft 602 is driven by a driving motor 603. The two traction ropes 601 are connected to both sides of the recovery trolley 4. The driving motor 603 drives the rotating shaft 602 to rotate to control the retraction and release of the traction rope 601, thereby applying a pulling force to both sides of the recovery trolley 4 at the same time. In this way, the stability of the recovery trolley 4 during the movement can be improved, and the recovery trolley 4 can be prevented from deviating from the track 5. More specifically, the outer side of the retractable wheel 604 has an annular groove, and the width of the annular groove matches the diameter of the traction rope 601. When the traction rope 601 is wound in the annular groove, no deviation will occur, which can improve the synchronization of the two traction ropes 601 being pulled back.

[0043] Preferably, see Figure 8The inclined section 502 is arranged in a dustproof housing 9. A lifting door 901 is arranged at one end of the dustproof housing 9 close to the cylinder 201. Two notches 902 are arranged at the bottom of the lifting door 901. When the lifting door 901 is lowered to the bottom, the two horizontal sections 501 are located in the two notches 902. When the powder in the recovery trolley 4 needs to be dumped, the lifting door 901 is first controlled to rise upward, and then the traction mechanism 6 is controlled to pull the recovery trolley 4. When the recovery trolley 4 completely reaches the top of the inclined section 502, the lifting door 901 is controlled to close. When the powder in the recovery trolley 4 is subsequently poured out, it can be blocked by the dustproof housing 9 to avoid dust.

[0044] For details, see Fig.10 , Fig.14 The two inclined sections 502 are arranged above the two inclined support blocks 503, and a material receiving box 10 is arranged between the two support blocks 503 for receiving the powder poured out of the recovery trolley 4. A second opening 903 is provided at the bottom of the end of the dustproof shell 9 away from the cylinder 201. The shape of the second opening 903 matches the shape of the material receiving box 10. The second opening 903 is convenient for taking out the material receiving box 10 for cleaning, and after the material receiving box 10 is pushed into the dustproof shell 9 from the second opening 903, the outward end of the material receiving box 10 can block the second opening 903 to prevent powder from overflowing.
