[0002] Aluminum alloy plates have a series of advantages such as light weight, high strength, and good plasticity, so they have become the preferred materials in the building material field and are often made into aluminum single-plate curtain walls for use. Spraying is an important step in the production of aluminum single-plate curtain walls. Spraying special coatings on the outer surface of aluminum single-plate curtain wall products can improve the corrosion resistance and service life of the aluminum single-plate curtain wall products. The existing spraying operation is carried out in a dedicated spraying room, and workers hold spray gun equipment to spray the aluminum single-plate curtain wall products as a whole. The existing spraying operation mode has low efficiency, and the paint spray will pose a health threat to workers.

Detailed Embodiment

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0031] AsFigures 1-5 A double-station aluminum plate spraying operation system as shown includes a spraying chamber 1, a workpiece rack 2, and a spray gun device 3. A spraying operation cavity 13 is provided in the spraying chamber 1, and the spraying operation is carried out in the spraying operation cavity 13. As Figure 2 shown, first inlets and outlets 11 and second inlets and outlets 12 are symmetrically formed on the left and right sides of the spraying chamber 1. The workpiece rack 2 is installed through the spraying chamber 1, and the length of the workpiece rack 2 is greater than the length of the spraying chamber 1. The first inlets and outlets 11 and the second inlets and outlets 12 communicate with the spraying operation cavity 13 to form a left-right channel (also the length direction of the spraying chamber 1) in the spraying chamber 1. The workpiece rack 2 includes a bottom plate 21 and a partition plate 22. The partition plate 22 is vertically installed at the central position of the upper plane of the bottom plate 21. First spraying stations 25 and second spraying stations 26 are formed on both sides of the partition plate 22. Hanging rack assemblies 27 are installed at both the first spraying stations 25 and the second spraying stations 26. The hanging rack assemblies 27 are used for hanging aluminum single-plate curtain wall products. The first inlets and outlets 11 and the second inlets and outlets 12 are used as the movement channel openings of the workpiece rack 2. The workpiece rack 2 can move in and out through the first inlets and outlets 11 and the second inlets and outlets 12. As the workpiece rack 2 moves, the first spraying stations 25 and the second spraying stations 26 alternately enter the spraying operation cavity 13. For the stations that enter the spraying operation cavity 13, the aluminum single-plate curtain wall products hung on them can be subjected to spraying operations. For the stations that do not enter the spraying operation cavity 13, workers can perform disassembly, replacement, and other operations on the aluminum single-plate curtain wall products. In the present invention, the sizes of the first inlets and outlets 11 and the second inlets and outlets 12 are the same, and the width of the bottom plate 21 of the workpiece rack 2 matches the width of the door openings of the first inlets and outlets 11 and the second inlets and outlets 12, so as not to affect the movement operation of the workpiece rack 2. Since there are front and back sides of the aluminum single-plate curtain wall products in the hanging state that need to be sprayed, two spray gun devices 3 are designed and installed in the present invention. The two spray gun devices 3 are symmetrically installed on the front and back sides of the spraying chamber 1 respectively. The spray gun device 3 includes a box body 31 and a gun beam 32. The box body 31 communicates with the spraying operation cavity 13. The gun beam 32 is installed in the box body 31 in a lifting and movable manner. Spray guns 33 are installed on the gun beam 32, and the muzzles of the spray guns 33 face the spraying operation cavity 13. As the gun beam 32 rises or falls, the spray guns 33 automatically perform spraying operations on the end faces of the hanging aluminum single-plate curtain wall products.

[0032] As Figure 1 and Figure 2As shown, the partition board 22 is dimensionally matched with the cross-sectional dimension of the spraying operation chamber 13. As the workpiece rack 2 moves, the partition board 22 moves along the length direction of the spraying operation chamber 13. The door opening dimensions of the first inlet / outlet 11 and the second inlet / outlet 12 are smaller than the dimension of the partition board 22. When the partition board 22 is in contact with the first inlet / outlet 11 or the second inlet / outlet 12, the partition board 22 can seal the first inlet / outlet 11 or the second inlet / outlet 12 from the inside of the spraying operation chamber 13. A first sealing plate 23 and a second sealing plate 24 are vertically installed on the bottom plate 21 of the workpiece rack 2. The first sealing plate 23 and the second sealing plate 24 are symmetrically installed on both sides of the partition board 22. The distances between the first sealing plate 23 and the second sealing plate 24 and the partition board 22 are the same. The outer dimensions of the first sealing plate 23 and the second sealing plate 24 are larger than the door opening dimensions of the first inlet / outlet 11 and the second inlet / outlet 12. The first sealing plate 23 and the second sealing plate 24 cannot enter the spraying operation chamber 13. However, when the first sealing plate 23 and the second sealing plate 24 are in contact with the first inlet / outlet 11 and the second inlet / outlet 12, they can seal the first inlet / outlet 11 and the second inlet / outlet 12 from the outside of the spraying chamber 1. Based on this design principle, in the present invention, the first sealing plate 23 and the partition board 22 form a pair. The paired first sealing plate 23 and partition board 22 can simultaneously seal the first inlet / outlet 11 and the second inlet / outlet 12. This pairing situation occurs when the workpiece rack 2 moves to the right. The first sealing plate 23 seals the first inlet / outlet 11 from the outside, and the partition board 22 seals the second inlet / outlet 12 from the inside. The second sealing plate 24 and the partition board 22 also form a pair. The paired second sealing plate 24 and partition board 22 can also simultaneously seal the first inlet / outlet 11 and the second inlet / outlet 12. This pairing situation occurs when the workpiece rack 2 moves to the left. The second sealing plate 24 seals the second inlet / outlet 12 from the outside, and the partition board 22 seals the first inlet / outlet 11 from the inside. After the first inlet / outlet 11 and the second inlet / outlet 12 are sealed, a relatively enclosed working environment is formed inside the spraying chamber 1, and the paint mist generated by spraying will not escape to the outside of the spraying chamber 1 to ensure the operation safety. After the spraying chamber 1 is sealed, there must be a spraying station inside the spraying chamber 1, and the other spraying station must be located outside the spraying chamber 1.

[0033] As Figure 2As shown, the rack assembly 27 includes a top beam 271 and a T-shaped frame 272. The top beam 271 is fixed above the bottom plate 21. The two ends of the top beam 271 are fixedly connected to the partition plate 22 and the first sealing plate 23 (or the second sealing plate 24). The installation height of the top beam 271 is lower than the door opening height of the first inlet and outlet 11 and the second inlet and outlet 12. The width of the top beam 271 is smaller than the door opening width of the first inlet and outlet 11 and the second inlet and outlet 12. This does not affect the in-and-out movement of the workpiece rack 2. A hanging space for the aluminum single-plate curtain wall product is formed between the top beam 271 and the bottom plate 21. The T-shaped frame 272 is fixedly connected to the partition plate 22 and the first sealing plate 23 (or the second sealing plate 24). Connected to the lower plane of the top beam 271, the T-shaped frame 272 includes a vertical plate 2721, and a plurality of evenly distributed hook holes 2722 are opened along the length direction of the vertical plate 2721. Angle codes will be installed on the edge of the aluminum single plate curtain wall product, and rope hooks can be installed using the angle codes. The aluminum single plate curtain wall product can be hung on the T-shaped frame 272 through the rope hooks. The hook holes 2722 are used to install rope hooks. Large pieces of aluminum single plate curtain wall products can be hung separately for spraying, and small pieces of aluminum single plate curtain wall products can be hung after being combined to make full use of the effective spraying area of ​​the spraying operation chamber 13 (referring to the area that can be effectively covered by all spray guns 33).

[0034] like Figure 4 and Figure 5As shown, the spray gun device 3 also includes a lifting power assembly 34, which is connected to the gun beam 32 in a transmission manner to drive the gun beam 32 to move up and down. The lifting power assembly 34 includes a top platform 341, a bottom platform 342, a screw 343 and a guide rod 344. The top platform 341 is fixed to the top of the inner side of the box body 31, and the bottom platform 342 is fixed to the bottom of the inner side of the box body 31. The top platform 341 and the bottom platform 342 are arranged in parallel. The screw 343 is rotatably installed between the top platform 341 and the bottom platform 342. The two guide rods The guide rods 344 are symmetrically and fixedly installed on both sides of the screw rod 343. The gun beam 32 is installed on the two guide rods 344 and is threadedly connected with the screw rod 343. A motor 345 is installed on the top of the box body 31. The output end of the motor 345 is connected to the screw rod 343. When the motor 345 is started, it can drive the rotation of the screw rod 343. The guide rods 344 play a role in guiding the movement of the gun beam 32. When the screw rod 343 rotates, the gun beam 32 can move along the length direction of the guide rods 344. Since the guide rods 344 are installed vertically, the gun beam 32 2 can realize lifting movement. Several spray guns 33 are evenly arranged in a straight line along the length direction of the gun beam 32. Arranging multiple spray guns 33 can increase the spray coverage area, so that a larger area of ​​the object can be sprayed at one time. When the spray gun 33 is turned on, the lifting of the gun beam 32 is started. The gun beam 32 is initially at the upper limit position, so it is sprayed from top to bottom, and then the gun beam 32 returns to the upper limit after reaching the bottom, forming a bottom-up spraying. The muzzle of the spray gun 33 faces the spraying operation chamber 13, and the paint mist sprayed from the muzzle can be applied to the objects in the suspended state. On the end surface of the aluminum single plate curtain wall product, the muzzle of the spray gun 33 does not enter the spraying operation chamber 13 to prevent it from being hit by the moving partition board 22. A plurality of infusion pipes 35 are installed on the top of the box body 31. A paint tank is installed on the side of the system. The infusion pipe 35 is connected to the paint tank to transport the paint for spraying operation. The infusion pipe 35 corresponds to the spray gun 33 one by one and the pipelines are connected. The connecting pipeline between the infusion pipe 35 and the spray gun 33 adopts a telescopic hose, which can meet the connection requirements during the telescopic movement of the spray gun 33.

[0035] like Figure 2 and Figure 3As shown, spraying control elements 28 are installed on both the first sealing plate 23 and the second sealing plate 24. Two symmetrically arranged switch grooves 111 are provided at the top of the spraying chamber 1. The two switch grooves 111 are respectively set corresponding to the first inlet / outlet 11 and the second inlet / outlet 12. The spraying control element 28 includes a switch striker 281. The switch striker 281 is fixedly connected to the first sealing plate 23 and the second sealing plate 24. A switch holder 282 is fixedly installed in the switch groove 111. A switch 283 is installed on the switch holder 282. The switch holder 282 covers the switch groove 111 to form a concave installation effect for the switch 283. The switch 283 is arranged on the movement track line of the switch striker 281. When the switch striker 281 moves towards the switch 283, it can squeeze and trigger the corresponding switch 283, and the switch 283 gives an electrical signal to control the start of the spray gun device 3. In the present invention, one switch 283 is installed at each of the first inlet / outlet 11 and the second inlet / outlet 12. When the workpiece rack 2 moves to the right, the switch striker 281 on the first sealing plate 23 can trigger the switch 283 of the first inlet / outlet 11. After the switch 283 is triggered, it indicates that the spraying chamber 1 is completely closed, and the first spraying station 25 completely falls into the spraying operation cavity 13, and spraying operations can be carried out. Similarly, when the workpiece rack 2 moves to the left, the switch striker 281 on the second sealing plate 24 can trigger the switch 283 of the second inlet / outlet 12. After the switch 283 is triggered, it indicates that the spraying chamber 1 is completely closed, and the second spraying station 26 completely falls into the spraying operation cavity 13, and spraying operations can be carried out.

[0036] After the spraying operation, there is still spraying liquid paint mist in the spraying chamber 1. If the workpiece rack 2 is directly pulled, it will cause the escape of the paint mist and pollute the workshop environment. Therefore, as Figure 1As shown, in the present invention, an exhaust pipe 36 is connected to the outer wall of the box body 31 of the spray gun device 3, and the exhaust pipe 36 is connected to the exhaust gas extraction equipment. After the spraying operation is completed, the exhaust pipe 36 forms an exhaust gas extraction effect to quickly extract the paint mist, so that the subsequent pulling of the workpiece rack 2 will not cause paint mist pollution. A ventilation pipe mouth 14 is installed on the top of the spray room 1, and an opening and closing control valve 141 is installed on the ventilation pipe mouth 14. The opening and closing control valve 141 controls the opening and closing of the ventilation pipe mouth 14. During the extraction and exhaust of paint mist and spraying operations, the ventilation pipe mouth 14 needs to be normally closed. After the extraction and exhaust of paint mist is completed, the ventilation pipe mouth 14 is opened to introduce outside air to balance the internal and external air pressures of the spray room 1. Only when the internal and external air pressures are balanced, the workpiece rack 2 can be pulled smoothly. The present invention is equipped with two signal lights 15 on the top of the spray room 1, and the two signal lights 15 are respectively set corresponding to the first spraying station 25 and the second spraying station 26 (the left signal light 15 is on the left side). The signal light 15 corresponds to the first spraying station 25, and the right signal light 15 corresponds to the second spraying station 26. The signal light 15 has three color states. Workers can intuitively judge the equipment status according to the color change of the signal light 15. The signal light 15 is divided into red, yellow and green. The flashing red light represents that the aluminum single plate curtain wall product on the corresponding spraying station is undergoing spraying operation. The flashing yellow light represents that the corresponding spraying station has just entered the spraying operation chamber 13 and landed, prompting that the spray gun device 3 can be turned on. The flashing green light represents that the corresponding spraying station is outside the spraying room 1. The conversion from green light to yellow light requires the switch 283 on the corresponding side of the signal light 15 to be triggered to generate an electrical signal and then start. The present invention needs to set the spray gun device 3 to be turned on only after the yellow light flashes, and the spray gun device 3 cannot be turned on under the green light condition. After the spraying operation is completed, the red light turns to yellow light. The present invention needs to set the workpiece rack 2 to be moved under the yellow light or green light condition.

[0037] To facilitate the movement of the workpiece rack 2, as Figure 1 As shown, two parallel rails 4 are laid on the ground below the spray room 1, and the length of the rails 4 should meet the maximum stroke of the workpiece rack 2. Two sets of wheels 211 are installed under the bottom plate 21 of the workpiece rack 2, and one set of wheels 211 is arranged corresponding to one rail 4. The workpiece rack 2 forms a trolley structure for easy pushing and moving. The first sealing plate 23 and the second sealing plate 24 are fixedly connected with a handle 231, and the handle 231 is installed on the outside for the convenience of workers to push by hand.

[0038] A method for spraying an aluminum plate is implemented by using a double-station aluminum plate spraying system, and includes the following steps:

[0039] (a) In the initial state of the system, the first spraying station 25 is outside the spraying room 1, and the signal light 15 corresponding to the first spraying station 25 is flashing green. The worker performs the operation of hanging the aluminum single plate curtain wall product on the first spraying station 25. At this time, the second spraying station 26 is in the spraying operation chamber 13, and the signal light 15 corresponding to the second spraying station 26 is flashing yellow. Since the second spraying station 26 is unloaded, the spray gun device 3 is not started;

[0040] (b), Push the workpiece rack 2 to make the workpiece rack 2 move towards the right side of the spraying chamber 1, switch the first spraying station 25 into the spraying chamber 1, and the second spraying station 26 is gradually exposed outside the spraying chamber 1. After the first spraying station 25 completely enters, the signal lamp 15 corresponding to the first spraying station 25 flashes yellow. After the second spraying station 26 comes outside the spraying chamber 1, the signal lamp 15 corresponding to the second spraying station 26 flashes green;

[0041] (c), The signal lamp 15 corresponding to the first spraying station 25 flashes yellow, indicating that the workpiece rack 2 has moved in place to the right. At this time, the spraying chamber 1 is closed, the spray gun device 3 is started inside the spraying chamber 1, the signal lamp 15 flashes red, and the spray gun device 3 automatically sprays the aluminum single-board curtain wall product at the first spraying station 25. At this time, the second spraying station 26 is switched and exposed outside the spraying chamber 1, and the worker hangs the aluminum single-board curtain wall product on the second spraying station 26;

[0042] (d), After the spraying operation at the first spraying station 25 is completed, the waste gas exhaust operation (opening the exhaust pipe 36 to extract gas) and the ventilation and air supplement operation (opening the ventilation pipe orifice 14 for ventilation) are sequentially performed inside the spraying chamber 1, and then the signal lamp 15 turns to flash yellow;

[0043] (e), Push the workpiece rack 2 to the left to switch the second spraying station 26 to enter the spraying chamber 1 for operation. At this time, the worker replaces the aluminum single-board curtain wall product at the first spraying station 25;

[0044] (f), Continuously switch the first spraying station 25 and the second spraying station 26 to enter the spraying chamber 1 for continuous spraying production.

[0045] The present invention uses the spray gun device 3 to complete the automatic spraying operation. Since manual spraying is not required, the thickness dimension of the spraying chamber 1 can be designed to be smaller. The present invention has the advantage of small floor area. The present invention can meet the demand for unmanned spraying operation. The worker only needs to perform safe operations such as hanging products outside the spraying chamber 1. The present invention solves the problem of threatening the health of workers during traditional spraying operations. The present invention designs a working mode of double-station alternating entry and exit, and uses the fragmented time of spraying operation at one station to hang products on the other station. The present invention can have the advantage of good production continuity and can improve the spraying operation efficiency.

[0046] The above is only the preferred implementation manner of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and retouches made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
