Description

Technical Field

[0001] This invention belongs to the field of spraying technology, and specifically relates to a spraying system for spraying energy storage cabinets. Background Technology

[0002] The energy storage cabinet coating process mainly includes the following steps:

[0003] 1. Preparation before spraying: First, the surface of the energy storage cabinet needs to be cleaned to remove stains and impurities. Then, it needs to be ground and polished to make the surface smooth and flat. Finally, it needs to be degreased and derusted to ensure the surface is clean and free of contamination.

[0004] 2. Applying Primer: The purpose of applying primer is to improve the adhesion of the energy storage cabinet surface, protect its outer shell from oxidation and corrosion, and resist UV damage. Primers are generally made of various materials such as acrylic, polyurethane, and alkyd; different types of primers can be selected according to needs.

[0005] 3. Intermediate Coat: The purpose of the intermediate coat is to fill the pores and imperfections of the primer, improve the smoothness of the energy storage cabinet surface, and also increase the density and hardness of the energy storage cabinet. Intermediate coats can generally be made of various materials such as colorless environmentally friendly water-based acrylic intermediate coats and colorless environmentally friendly water-based polyurethane intermediate coats.

[0006] 4. Finishing Coating: Finishing coating is used to improve the gloss and protective ability of the energy storage cabinet surface, preventing damage from external dust, pollution, and friction during use. Epoxy resin finishing coating or polyurethane finishing coating are common choices.

[0007] 5. Apply topcoat or varnish: Applying topcoat makes the surface of the energy storage cabinet more vibrant and aesthetically pleasing, and also extends the lifespan of the cabinet's outer shell. The choice between topcoat and varnish should be based on the color of the energy storage cabinet.

[0008] Due to the highly complex external and internal structures of energy storage cabinets, painting operations are generally difficult, requiring specialized skills and experience, and demanding a high level of expertise from operators. Furthermore, the painting equipment needs to be adjusted for various parameters, such as flow rate, speed, and temperature, according to actual needs, further complicating the operation. Moreover, painting the entire energy storage cabinet as a single unit can easily result in poor paint quality, while painting each component individually and then assembling them into a single unit leads to lower overall efficiency and a heavier workload.

[0046] To facilitate understanding of the present invention, a more comprehensive description will be given below with reference to the accompanying drawings.

[0047] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0049] Please refer to Figures 1-3 The robot at station A is equipped with two spray guns to spray area A (100A). One spray gun uses a 60-degree corner nozzle, while the other uses a straight nozzle, in order to adapt to different spraying areas and carry out flexible and efficient spraying operations.

[0050] When the workpiece 100 to be sprayed (i.e. the product to be sprayed energy storage cabinet) enters the working area of ​​Station A, the 6-axis robot of Station A sprays the reinforcing rib 101A angle and the folding plate 102A on the top of the workpiece 100, that is, the reinforcing rib 101A angle and the folding plate 102A in the A spraying area 100A corresponding to the dashed box in the attached figure.

[0051] Please refer to Figures 1-3 The robot at station C is equipped with two spray guns to spray the C spraying area 100C. One spray gun uses a 90-degree corner nozzle, and the other uses a straight nozzle, in order to adapt to different spraying areas and carry out flexible and efficient spraying operations.

[0052] When the workpiece 100 to be sprayed enters the working area of ​​station C, the 6-axis robot of station C covers the top folded plate and the hanging chain of the workpiece 100. The spraying area 100C is the inner side of the top left and right side plates, as shown in the right figure 100C (when the top U-axis enters the gun, it is necessary to avoid the missed spraying area formed by the chain. The spraying of the C station robot gun is fully supplemented).

[0053] Please refer to Figures 4-6 Station B employs a 4-dimensional axial (Z-axis 104B reciprocating up and down, U-axis telescopic forward and backward, R-axis rotation, Y-axis 103B synchronously accompanying) multi-functional spraying reciprocating machine combination. Two sets of U-axis 101B are mounted on the left side of Z-axis 104B, and two sets of UR-axis 102B are mounted on the right side. Z-axis 104B rests on the accompanying Y-axis 103B, enabling the spray gun to dynamically track and complete the spraying of workpiece 100. The two sets of U-axis spray guns on the left mainly spray the internal cavity of the U-groove of the bracket 105B behind the door post 107B; the two sets of UR-axis spray guns on the right spray the back of the cabinet column 106B. This is achieved through pre-programming to coordinate the overall spraying of the station. Forward and backward movement refers to moving towards / away from the rear side wall of the cabinet (i.e., the side wall opposite the opening). Left and right movement refers to reciprocating motion parallel to the conveying direction of the conveying device.

[0054] When the workpiece 100 to be sprayed enters the working area of ​​station B, spraying is performed on the inner cavity of the U-shaped groove of workpiece 100 and the back of the middle column 106B. First, as the Y-axis 103B tracks the chain speed and starts, the two UR axes on the right extend and rotate to point the spray gun at the back of the middle column 106B. Then, the Z-axis 104B moves up and down to complete the spraying of the back of the column 106B. After the spraying is completed, the UR axes retract to the standby position, and then the Y-axis 103B stops tracking and quickly returns to the origin. Next, after the door post 107B of workpiece 100 reaches the predetermined position, the two U-axis on the left enter the doorway. After the U-shaped groove cavity reaches above the spray gun, the Y-axis 103B... B starts the synchronous tracking chain operation. The two U-axis on the left reciprocate to spray the inner cavity area of ​​the bracket 105BU. After spraying is completed, the Y-axis 103B moves rapidly in the direction of chain movement at a speed greater than the chain speed. After the spray gun moves away from the door post 107B, the two U-axis on the left retract to their original position. Finally, the Y-axis 103B quickly returns to the work origin to wait for the next spraying position. This process is repeated to complete the spraying of the inner cavity of the bracket 105BU and the back of the post 106B of the entire cabinet. The inner cavity of the U-shaped groove of the bracket 105B faces downward.

[0055] Please refer to Figure 7 Station D uses a one-dimensional axial (rotational swing axis), with three spray guns 101D equipped with 90-degree corner nozzles mounted on the rotating axis. The spray gun nozzles are aligned with the position of the deep groove on the outer bottom of the workpiece 100 for fixed-point spraying.

[0056] When the workpiece enters the working area of ​​station D, the rotating shaft of station D swings within a range of 10 to 30 degrees to the left and right to enhance the spraying of the ribs in the deep groove without dead angles. At the same time, three automatic spray guns start automatically. When the workpiece stops, the spray guns also stop spraying synchronously. When the workpiece moves, the spray guns continue spraying until the entire cabinet is sprayed.

[0057] Please refer to Figures 8 to 9 Station E employs a three-dimensional axial (Z-axis 103E reciprocating up and down, X-axis 104E telescopic forward and backward, Y-axis 105E synchronously accompanying) multi-functional reciprocating spraying machine combination. The Z-axis 103E carries eight spray guns E100 on each side of an integrated gun holder 101E. The Z-axis 103E rests on the accompanying Y-axis 105E, enabling the spray guns to dynamically track and accompany the workpiece 100 during spraying. The spray guns on both sides simultaneously complete the surface spraying of each end plate 102E. This is achieved through pre-programming to coordinate the overall spraying process of the station. The end face of the end plate 102E includes the left inner surface, left outer surface, right inner surface, right outer surface of the workpiece 100, as well as the left and right sides of the doorposts, brackets, and columns.

[0058] When workpiece 100 enters the working area of ​​station E, the X, Y, and Z axes 103E move in unison, and the spray guns start. The X axis 104E slowly extends into the workpiece 100 at a speed of 100mm / s to 200mm / s, the Y axis 105E keeps pace with the conveyor chain at the same speed, and the Z axis 103E makes a small up-and-down reciprocating motion in the spacious area inside, improving the automatic spraying coverage of the spacious area; each end face is fully sprayed during the process of the spray guns E100 moving in and out on both sides of the entire gun frame 101E in station E.

[0059] Please refer to Figure 10 The L station adopts a one-dimensional axial (Z-axis up and down movement) design. Eight spray guns 100L equipped with 90-degree corner nozzles are mounted on the gun holder. The spray guns are evenly distributed at 220mm intervals and maintain a spraying distance of 250mm from the bottom surface of the workpiece 100 for fixed spraying to achieve the spraying requirement of full coverage of the appearance surface.

[0060] When workpiece 100 enters the working area of ​​station L, the eight automatic spray guns on station L start spraying powder; when workpiece 100 stops, the spray guns also stop spraying synchronously; when workpiece 100 moves, the spray guns continue spraying until the entire cabinet is coated. The combination of station L and station D can fully achieve the required coating standards for both simple and complex coating surfaces on the bottom of workpiece 100.

[0061] Station L has a redundant configuration, which completely solves the problem of insufficient automatic spraying on the bottom of workpiece 100 and avoids workers having to go down to the bottom of workpiece 100 to work.

[0062] Please refer to Figures 11-12 Station F employs a three-dimensional axial (Z-axis 103F reciprocating up and down, X-axis telescopic forward and backward, Y-axis 104F synchronously accompanying) multi-functional reciprocating spraying machine combination. Four sets of automatic spray guns 100F are mounted on the left and right sides of Z-axis 103F, which rests on the accompanying Y-axis 104F, enabling the spray guns to dynamically track and complete the spraying of the workpiece 100. The gun holder uses two longitudinal and two transverse spray guns installed in opposite directions, with the spray guns on both sides encircling and focusing on the workpiece in the U-shaped groove 102F behind the gatepost 101F (corresponding to gatepost 107B of Station B). This is achieved through pre-programming to coordinate the overall spraying of the station.

[0063] When workpiece 100 enters the working area of ​​station F, the X, Y, and Z axes 103F work together simultaneously, and the spray gun starts. The X-axis quickly reaches the target area at a speed of 300mm / s to 400mm / s, while the Y-axis 104F follows and moves at the same speed as the conveyor chain. After the X-axis is in position, the Z-axis 103F moves up and down at a speed of 150mm / s to 200mm / s, spraying twice. After spraying, the X-axis quickly retracts, clearing the doorpost of workpiece 100, and the Y-axis 101F finishes and quickly returns to its origin to wait for the next doorpost 101F to be sprayed. The entire station F works in unison to complete the spraying of the deep U-shaped grooves 102F on the back of each doorpost 101F of the cabinet. The cabinet doorposts 101F are U-shaped columns facing inwards.

[0064] Please refer to Figures 13-14 In this embodiment, the left and right sides of the spray gun are viewed from behind the workpiece 100 and towards the opening. Station H adopts a two-dimensional axial (Z-axis reciprocating up and down, U-axis telescopic forward and backward) + fixed gun position, a multi-functional composite station. The left side of the Z-axis is equipped with a U-axis gun 100H-4 fixed on the top and a fixed spray gun 100H-2 for respraying complex parts. The right side is equipped with a U-axis spray gun 100H-3 for spraying the inner top surface H3 of workpiece 100 and a reciprocating U-axis spray gun 100H-1 for spraying the outer bottom of workpiece 100. The overall coordinated spraying of the station is achieved through pre-programming + laser automatic contour recognition.

[0065] When workpiece 100 enters the working area of ​​station H, the U-axis gun 100H-4 on the top left automatically avoids the hanger chain and begins spraying the outer top plane H4 of workpiece 100 at a speed of 150mm / s to 200mm / s; the fixed spray gun 100H-2 on the lower left automatically starts spraying in the area H2 to be sprayed through programming; the fixed spray gun 100H-3 on the top right extends its U-axis to the area to be sprayed after avoiding the hanger chain, and then the Z-axis independent slider 102H descends to the appropriate position to spray the inner top surface H3 of the workpiece; the U-axis gun H100-1 on the bottom right adaptively sprays the outer bottom surface H1 of workpiece 100 through automatic laser scanning recognition. When workpiece 100 stops, the spray gun also stops spraying synchronously; when workpiece 100 moves, the spray gun continues to spray until the entire cabinet is sprayed, and the U-axis retracts the gun to the standby position to wait for the next workpiece 100 to be sprayed.

[0066] Please refer to Figure 15Station G employs a three-dimensional axial (Z-axis 103G reciprocating up and down, X-axis 101G telescopic forward and backward, Y-axis 102G synchronously accompanying) multi-functional reciprocating spraying machine combination. Four automatic spray guns 100G with straight nozzles are mounted on the Z-axis 103G, evenly spaced at 480mm intervals. The spray guns 100G maintain a 250mm spraying distance from the inner surface of the workpiece 100 during reciprocating spraying, achieving uniform and efficient spraying of the inner surface 104G. This is achieved through pre-programming to coordinate the overall spraying process of the station. The inner surface 104G is the inner wall of the workpiece 100's inner cavity away from the opening, specifically the inner surface at the rear end of the workpiece 100's inner cavity.

[0067] When workpiece 100 enters the working area of ​​station G, the X-axis 101G, Y-axis 102G, and Z-axis 103G move in unison. X-axis 101G rapidly extends into the target spraying area at a speed of 400mm / s, maintaining a distance of 70mm close to the end face. During the X-axis 101G's entry into and exit from workpiece 100, Y-axis 102G maintains a constant speed and follows the conveyor chain. This is to ensure that the spray gun avoids missing a significant amount of spraying area before reaching the target spraying area. The automatic spraying coverage is achieved as follows: After X-axis 101G is in place, the spray gun is activated, while Z-axis 103G reciprocates up and down at a speed of 150-200 mm / s. As it approaches the other end, Y-axis 102G starts again, and X-axis 101G quickly retracts to avoid workpiece 100. After the spray gun exits workpiece 100, Y-axis 102G stops and quickly returns to its origin, awaiting the spraying of the next inner side 104G. This process is repeated to complete the automatic spraying of the inner side 104G of workpiece 100. When workpiece 100 stops, the spray gun also stops spraying synchronously; when workpiece 100 moves, the spray gun continues spraying until the entire cabinet is coated.

[0068] Please refer to Figure 16 Station K employs a two-dimensional axial (Z-axis reciprocating up and down, X-axis 101K telescopic forward and backward) reciprocating machine combination. Three straight-nozzle automatic spray guns 100K are mounted on the Z-axis, evenly spaced at 900mm intervals, maintaining a 250mm spraying distance from the outer surface of workpiece 100 for reciprocating spraying to achieve uniform and efficient spraying of the outer surface 104K. This is achieved through laser detection and adaptive spraying to coordinate the overall spraying process at the station. The outer surface 104K is the outer wall of workpiece 100 away from the opening, i.e., the outer surface of the rear end of workpiece 100.

[0069] When workpiece 100 enters the working area of ​​station K, the X-axis 101K, combined with the position data detected by the laser, automatically maintains a spraying distance of 250mm from workpiece 100mm, while the Z-axis sprays the outer surface 104K of workpiece 100 evenly from top to bottom. When workpiece 100 stops, the spray gun also stops spraying synchronously; when workpiece 100 moves, the spray gun continues spraying until the entire rear outer surface of the workpiece cabinet is sprayed.

[0070] Please refer to Figure 17 and Figure 18 Station I employs a two-dimensional axial design (Z-axis reciprocating up and down, U-axis telescopic forward and backward) + fixed gun position, creating a multi-functional composite workstation. On the left side of the Z-axis, a fixed top U-axis spray gun 100I-1 and a spray gun 100I-2 are mounted for directional spraying of complex parts and areas inaccessible to other workstations. On the right side, a U-axis spray gun 100I-3 is mounted for spraying the top inner surface (I3) of the workpiece, a U-axis spray gun 100I-4 for directional spraying of the back of the top beam (I4), and a reciprocating U-axis spray gun 100I-5 for spraying the outer bottom (I5) of the workpiece. The overall coordinated spraying of this station is achieved through pre-programming and automatic laser contour recognition.

[0071] When workpiece 100 enters the working area of ​​station I, the top U-axis gun 100I-1 on the left side automatically avoids the hanging chain and begins spraying the outer top plane I1 of workpiece 100 at a speed of 150mm / s to 200mm / s. The spray gun 100I-2, fixed at a specific position on the left, is programmed to automatically activate and spray the area I2 to be sprayed. The area I2 to be sprayed includes the front of the top beam I101 and the area above and below the opening of workpiece 100 on the front, specifically the area above and below the opening of the spray gun 100I-2 on the front of workpiece 100 in the diagram. The spray gun 100I-3 on the top right U-axis extends its U-axis to the area to be sprayed after avoiding the hanging chain. Then, the Z-axis independent slider descends to the appropriate position to spray the inner side I3 of the top of workpiece 100. The spray gun 100I-4 on the middle right U-axis automatically avoids the workpiece 100 door post and extends into the back I4 of the top beam I101 of the door post for fixed-point spraying. The spray gun 100I-5 on the bottom right U-axis adaptively sprays the outer bottom surface I5 of workpiece 100 through laser scanning automatic dynamic recognition. When workpiece 100 stops, the spray gun also stops spraying synchronously. When workpiece 100 moves, the spray gun continues spraying until the entire cabinet is sprayed. The U-axis then retracts the guns to the standby position to wait for the next workpiece 100 to be sprayed.

[0072] Please refer to Figure 19 Station J employs a three-dimensional axial (Z-axis 102J reciprocating up and down, U-axis 101J telescopic forward and backward, Y-axis synchronously accompanying) multi-functional reciprocating spraying machine combination. Two sets of U-axis 101J are mounted on Z-axis 102J, which sits on the accompanying Y-axis, enabling the spray gun to follow and complete the spraying of workpiece 100 in a dynamic state. The spray guns on the two sets of U-axis 101J mainly perform automatic spraying on the areas of the top 103J and bottom 104J of the inner cavity of workpiece 100; this is achieved through pre-programming to complete the overall coordinated spraying of the station.

[0073] When workpiece 100 enters the working area of ​​station J, the U-axis 101J, Y-axis, and Z-axis 102J move in tandem. The Z-axis 102J quickly and automatically slides to a position 250mm from the spraying surface of workpiece 100, the spray gun is turned on, and the U-axis 101J slowly extends into the workpiece 100 at a speed of 150mm / s to 200mm / s, maintaining a distance of 70mm close to the end face. After reaching the deepest part of the workpiece 100, the Y-axis stops its accompanying motion, and the U-axis 101J continues its original reciprocating motion to fully spray the top 103J and bottom 104J of the inner cavity of workpiece 100. When approaching the other end, the Y-axis starts its accompanying motion again, and the U-axis 101J maintains its speed and returns to the working origin to turn off the gun and stop spraying. After the spray gun exits the workpiece 100, the Y-axis stops its accompanying motion and quickly returns to the origin to wait for the spraying of the top and bottom surfaces of the next section. In this way, the automatic spraying of the top and bottom surfaces of the inner cavity of workpiece 100 is completed. When the U-axis 101J enters the workpiece 100 stage and exits the workpiece 100 stage, the Y-axis maintains the same speed as the conveyor chain and tracks it. This is to ensure that the spray gun does not miss a large amount of spraying area before reaching the target spraying area, which would affect the automatic spraying coverage. When the workpiece 100 stops, the spray gun also stops spraying synchronously. When the workpiece 100 moves, the spray gun continues to spray until the entire cabinet is sprayed.
