[0002] Existing cup spraying equipment generally includes a ground rail, a fixture and a spray gun. The cup is installed on the ground rail through the fixture, and then the ground rail is started to transport the cup to the spray gun position to spray the outer side of the cup. However, in actual spraying, it is found that due to the different specifications of the cup, the current spray gun cannot achieve uniform spraying of different cups. For example, when spraying a larger cup, the current spray gun can only spray a part of the cup, or it can spray the entire cup.

[0020] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0021] As described in the background art, due to the different specifications of the cup bodies, the current spray guns cannot achieve uniform spraying of different cup bodies.

[0022] Therefore, the present application creatively proposes a spraying production line, which includes a conveyor line, a support component, a spraying component, a rust removal component and a dust removal component. Before spraying the workpiece to be coated, the workpiece to be coated is first placed on the support component. The inner cavity of the workpiece to be coated will pressurize at least one supporting structure to make it close to the pillar, so that the supporting structure can stably support the workpiece to be coated. The conveyor line is then used to transport the workpiece to be coated to the rust removal component and the dust removal component for processing. After the processing is completed, the support component with the workpiece to be coated is continued to be transported to the spraying component. At this time, the positioning structure on the pressurized support structure enters the detection distance of its corresponding detection element, thereby starting the spray gun corresponding to the detection element, and then the workpiece to be coated is sprayed by the spray gun, that is, the corresponding support structure is pressurized by the shape of the inner cavity of the workpiece to be coated, so that the positioning structure on the corresponding support structure enters or leaves the detection distance of the corresponding detection element, thereby controlling the corresponding spray gun in the preset direction to work, and finally achieving uniform spraying of the outer side of the workpiece to be coated.

[0023] The present application will be described in detail below through specific embodiments.

[0024] Reference Figures 1 to 6As shown, an embodiment of the present application provides a spraying production line, which includes a conveyor line 1, a support component 2, a spraying component 3, a rust removal component 4 and a dust removal component 5, wherein the rust removal component 4 is configured to remove rust impurities in a workpiece 11 to be coated, and the dust removal component 5 is configured to remove dust in the workpiece 11 to be coated, the support component 2 is arranged on the conveyor line 1, and is configured to carry the workpiece 11 to be coated made of a non-electromagnetic shielding material; the spraying component 3 is arranged on at least one side of the conveyor line 1, and is configured to spray the workpiece 11 to be coated, and the conveyor line 1 is configured to convey the support component 2, wherein: the support component 2 includes a pillar 21, a plurality of positioning structures 22 made of a magnetic material, and a plurality of support structures 23 arranged in sequence along the axial direction of the pillar 21, A plurality of support structures 23 are elastically arranged on the pillar 21, and a plurality of positioning structures 22 are arranged one-to-one on the plurality of support structures 23; the spray assembly 3 includes a plurality of detection elements 31 and a plurality of spray guns 32 arranged in sequence along a preset direction, the plurality of detection elements 31 are electrically connected to the plurality of spray guns 32 one-to-one, and the detection ends of the plurality of detection elements 31 are relatively arranged one-to-one with the plurality of positioning structures 22; wherein the preset direction is parallel to the axial direction of the pillar 21; when the support assembly 2 carries the workpiece 11 to be coated, at least one support structure 23 is pressurized by the inner cavity of the workpiece 11 to be coated and approaches the pillar 21, so that the positioning structure 22 on the pressurized support structure 23 enters or leaves the detection distance of its corresponding detection element 31.

[0025] Furthermore, in some examples, the spraying production line further includes a heat treatment component 6 disposed between the dust removal component 5 and the spraying component 3 , and the heat treatment component 6 is configured to perform a heat treatment on the workpiece 11 to be coated.

[0026] In some examples, the spray painting production line includes two dust removal assemblies 5 .

[0027] In this embodiment, the spraying production line includes a rust removal component 4, a dust removal component 5, a heat treatment component 6 and a dust removal component 5 which are arranged in sequence; specifically, the rust removal component 4 includes a relatively independent rust removal chamber, the dust removal component 5 includes a relatively independent electrostatic dust removal chamber, and the heat treatment component 6 includes a relatively independent flame treatment chamber, and the chambers can be transported and transferred via ground rails.

[0028] It should be noted that heat treatment of the object 11 to be coated usually refers to baking the object 11 to increase the adhesion of the material used for spraying. Generally, in this embodiment, the object 11 to be coated is an ordinary glass cup, and the baking temperature is usually not high.

[0029] In addition, the spraying production line also includes a controller. During the actual spraying process, the environment of the workpiece 11 to be coated and the current spraying process requirements of the workpiece 11 to be coated will control the type of material used for spraying in the spray gun 32 and the material flow rate during spraying. Based on this, the user can adjust the spraying parameters by adjusting specific parameters in the controller. For example, the user can set a dynamic micro-adjustment of the flow rate of the spraying material based on the ambient temperature of the workpiece 11 to be coated, so as to improve the spraying effect of the workpiece 11 to be coated.

[0030] In a specific example, when the positioning structure 22 enters the detection distance of its corresponding detection element 31 , the corresponding spray gun 32 sprays the workpiece 11 to be coated.

[0031] In another specific example, when the positioning structure 22 is out of the detection distance of its corresponding detection element 31 , the corresponding spray gun 32 sprays the workpiece 11 to be coated.

[0032] Alternatively, in some examples, when a portion of the positioning structure 22 enters the detection distance of its corresponding detection element 31, the corresponding spray gun 32 sprays the workpiece to be coated 11, while the remaining positioning structures 22 are out of the detection distance of their corresponding detection elements 31, and the corresponding spray gun 32 starts to spray the workpiece to be coated 11. That is, when spraying the workpiece to be coated 11, some of the spray guns 32 are set not to work and some of the spray guns 32 are set to work, thereby achieving customized spraying of the workpiece to be coated 11.

[0033] In this embodiment, it is assumed that when all the positioning structures 22 enter the detection distance of the corresponding detection elements 31 , the corresponding spray guns 32 start spraying the workpiece 11 to be coated.

[0034] In some examples, the conveyor line 1 is a ground rail type conveyor assembly. Of course, the conveyor line 1 can also be other types of conveying equipment, as long as it can stably convey the workpieces 11 to be coated.

[0035] In this embodiment, the object 11 to be coated is a cup body made of glass. Of course, it can also be a container made of non-electromagnetic shielding materials such as plastic.

[0036] It should be noted that, under normal circumstances, the inner and outer cavities of the object to be coated 11, i.e., the cup body, are similar in shape. In this embodiment, the inner and outer cavities of the object to be coated 11 are both cylindrical, and correspondingly, the shape formed by the boundaries of the multiple support structures 23 is also cylindrical to match the inner cavity shape of the object to be coated 11. Of course, the inner cavity shape of the object to be coated 11 can also be other regular shapes such as a truncated cone, and correspondingly, the shape formed by the boundaries of the multiple support structures 23 is also a shape that matches the inner cavity of the object to be coated 11.

[0037] In some examples, the positioning structure 22 is generally made of magnetic materials such as iron, cobalt or alloys thereof.

[0038] It should be noted that during the spraying process, in order to improve the spraying uniformity of the workpiece 11 to be coated, a support 21 is generally provided to be rotatably connected to the ground rail, thereby driving the workpiece 11 to be coated to rotate relative to the spray gun 32 assembly. The rotation of the support 21 can be achieved by gears and racks. The specific implementation method is the existing technology and will not be repeated here.

[0039] It can be understood that when using the support component 2 to carry the workpiece 11 to be coated, the inner cavity cover of the workpiece 11 to be coated is generally arranged on the outside of the support component 2, and the top of the pillar 21 can be used to support the inner bottom wall of the workpiece 11 to be coated. The pressurized support structure 23 supports the inner side wall of the workpiece 11 to be coated, thereby improving the stability of the workpiece 11 to be coated during the spraying process.

[0040] Specifically, when spraying the workpiece 11 to be coated, the workpiece 11 to be coated is first placed on the support assembly 2. The inner cavity of the workpiece 11 to be coated will pressurize at least one supporting structure 23 to make it close to the pillar 21, so that the supporting structure 23 can stably support the workpiece 11 to be coated, and then the support assembly 2 with the workpiece 11 to be coated is transported to the spray assembly 3 through the conveyor line 1. At this time, the positioning structure 22 on the pressurized supporting structure 23 enters or leaves the detection distance of its corresponding detection element 31, thereby controlling the spray gun 32 corresponding to the detection element 31, and then the workpiece 11 to be coated is sprayed by the spray gun 32, that is, the corresponding supporting structure 23 is pressurized by the shape of the inner cavity of the workpiece 11 to be coated, so that the positioning structure 22 on the corresponding supporting structure 23 enters the detection distance of the corresponding detection element 31, thereby controlling the corresponding spray gun 32 to work in the preset direction, and finally achieving uniform spraying of the outer side of the workpiece 11 to be coated.

[0041] It is understandable that in order to improve the spraying efficiency, a plurality of support assemblies 2 are generally arranged on the conveyor line 1, and the plurality of support assemblies 2 are arranged at equal intervals along the conveying direction of the conveyor line 1, so that a plurality of parts to be coated 11 can be conveyed at the same time, so that the spraying assembly 3 can quickly spray the parts to be coated.

[0042] Furthermore, in some examples, the support assembly 2 further includes a sleeve (not shown), and a plurality of support structures 23 are elastically arranged on the sleeve, so as to adjust the installation of the support structure 23 in the support assembly 2 according to the specifications of the workpiece 11 to be coated. For example, before spraying, all the sleeves can be removed first, so that only the pillars 21 are left in the support assembly 2 on the conveyor line 1, and then the sleeves are installed on the corresponding pillars 21 according to the specifications of the workpiece 11 to be coated and the actual production needs, so as to install the workpiece 11 to be coated.

[0043] In some examples, the support structure 23 includes a bearing ring 231 and an elastic structure 232, the bearing ring 231 is connected to the pillar 21 through the elastic structure 232, and the positioning structure 22 is arranged on the bearing ring 231. When the workpiece 11 to be coated is placed on the support assembly 2, the inner wall of the workpiece 11 to be coated will apply pressure to the bearing ring 231 in contact with it, thereby compressing the elastic structure 232, so that the bearing ring 231 moves in a direction close to the pillar 21, and then drives the positioning structure 22 on the bearing ring 231 to move in a direction close to the pillar 21, so that the positioning structure 22 enters the detection distance of the corresponding detection element 31.

[0044] In an alternative example, refer to Figure 3 and Figure 5 As shown, the elastic structure 232 includes a connecting rod 2321 and an elastic member 2322. A clearance hole 2323 is provided at one end of the connecting rod 2321 away from the pillar 21. The clearance hole 2323 extends inward along the axis of the connecting rod 2321 to form a accommodating cavity 2324. One end of the elastic member 2322 is fixed in the accommodating cavity 2324, and the other end is connected to the supporting ring 231.

[0045] Specifically, when the elastic structure 232 is deformed, the elastic member 2322 is restricted by the accommodating cavity 2324 and is not easily twisted. At the same time, the rigidity of the connecting rod 2321 is utilized to improve the linear stability of the movement of the carrying ring 231 .

[0046] Further, in some examples, reference Figure 3 As shown, the elastic structure 232 also includes a plurality of connecting rods 2321 and a plurality of elastic members 2322, and the plurality of elastic members 2322 correspond to the plurality of connecting rods 2321 one by one, thereby further improving the linear stability of the radial movement of the bearing ring 231. In this embodiment, the plurality of connecting rods 2321 are equidistantly spaced around the circumference of the pillar 21.

[0047] Furthermore, in some examples, the support structure 23 also includes a guide rod 233 and a thrust rod 234, the elastic member 2322 is a cylindrical spring and is wound around the outside of the guide rod 233, and the elastic member 2322 is connected to the supporting ring 231 through the thrust rod 234; when the support assembly 2 carries the workpiece 11 to be coated, the thrust rod 234 can enter the accommodating cavity 2324 and abut against the guide rod 233.

[0048] Specifically, in actual spraying, when the inner cavity of the workpiece 11 to be coated is too small, the carrying ring 231 will be excessively squeezed, causing the positioning structure 22 on the carrying ring 231 to exceed the detection distance of its corresponding detection element 31. At this time, the maximum movement distance of the carrying ring 231 can be limited by setting the maximum distance between the thrust rod 234 and the guide rod 233, thereby ensuring that the positioning structure 22 on the carrying ring 231 is always within the detection distance of its corresponding detection element 31; and the guide rod 233 can also enhance the torsion resistance of the elastic member 2322.

[0049] In another alternative example, the elastic structure 232 may be an elastic column made of an elastic material, such as an elastic column made of rubber.

[0050] In some examples, reference Figure 3 As shown, the positioning structure 22 includes a plurality of positioning plates 221 , and the plurality of positioning plates 221 are arranged at intervals along the circumference of the corresponding support structure 23 .

[0051] Specifically, during the actual installation and operation of the support assembly 2, the support structure 23 will rotate. By providing a plurality of positioning plates 221 in the circumferential direction of the support structure 23, it can be ensured that the detection element 31 can detect the positioning structure 22 in time, thereby ensuring stable spraying of the spray gun 32 on the workpiece 11 to be coated.

[0052] Reference Figure 3 and Figure 4 As shown, in a replaceable example, the spraying production line also includes a collecting chamber 7 detachably connected to the pillar 21, and the collecting chamber 7 is arranged below the multiple supporting structures 23 to receive the falling materials used for spraying; the collecting chamber 7 includes a first cavity 71 and a second cavity 72, and the first cavity 71 and the second cavity 72 both have an avoidance groove 711. After the first cavity 71 and the second cavity 72 are assembled, the two avoidance grooves 711 form an avoidance hole 713 for avoiding the pillar 21; at least one of the first cavity 71 and the second cavity 72 has a plug-in portion 721, and at least one has an embedded portion 712, and the plug-in portion 721 and the embedded portion 712 are interference fit to assemble the first cavity 71 and the second cavity 72.

[0053] In another replaceable example, the spraying production line also includes a heating component, a drainage pipe, a recovery component and a collecting chamber 7 arranged along the conveying direction of the conveying line 1, and the collecting chamber 7 is located below the multiple support structures 23 to receive the falling paint, the collecting chamber 7 is detachably connected to each pillar 21, and is provided with a make way channel for avoiding the pillar 21, the heating component is used to heat the paint in the collecting chamber 7, and the recovery component is connected to the collecting chamber 7 through the drainage pipe to recover the paint in the collecting chamber 7.

[0054] It should be noted that the collecting chamber 7 can move synchronously with the conveying line 1, that is, move synchronously with all the pillars 21, so as to reduce the gap between the collecting chamber 7 and the pillars 21, so as to reduce the paint falling from the gap onto the conveying line 1. In this embodiment, a pass channel corresponding to each pillar 21 is opened in the collecting chamber 7.

[0055] Alternatively, the collecting chamber 7 can also be placed on the conveying line 1 to reduce the driving power required for the conveying line 1. In this case, the clearance channel of the collecting chamber 7 is a long strip channel, so that all the pillars 21 can be avoided at the same time. In this example, in order to reduce the paint falling on the conveying line 1 through the gap between the pillars 21 and the collecting chamber 7, the inner bottom wall of the collecting chamber 7 can be set with an upwardly protruding inverted triangle, so that the paint will fall into the collecting chamber 7 along the hypotenuse.

[0056] In this embodiment, the heating component is a resistance wire. By setting an internal interlayer space in the collection cavity 7 and then laying the resistance wire in the internal interlayer space, uniform heating of the paint in the collection cavity 7 is achieved, so that the paint remains in a fluid state for easy recovery.

[0057] Specifically, through an integral collection chamber 7 arranged along the conveying direction of the conveyor line 1, the paint falling from the conveyor line 1 can be collected in a centralized manner; at the same time, the paint can be recovered during the spraying process or after the spraying is completed. It is only necessary to turn on the heating component during the spraying process, and then turn on the recovery component during or after the spraying to achieve the paint recovery so that the paint can be reused later.

[0058] In addition, in some examples, the collection chamber 7 is detachably connected to the conveying line 1, and the user can remove the collection chamber 7 from the conveying line 1 after spraying and receiving as needed.

[0059] Specifically, during the spraying process, part of the material sprayed by the spray gun 32 will fall onto the conveyor line 1, which will affect the operation of the conveyor line 1 in the long run, while the collecting chamber 7 can collect most of the falling spraying materials in time, and the collecting chamber 7 will be transported along with the conveyor line 1. When the user removes the sprayed workpiece 11, the material in the collecting chamber 7 can be cleaned up in time. If there is too much material accumulated in some collecting chambers 7, the collecting chamber 7 can be usually disassembled to quickly clean the material in the collecting chamber 7.

[0060] In some examples, the conveyor line 1 includes a frame 12, and the spray assembly 3 also includes a mounting frame 33 slidably connected to the frame 12, and a plurality of spray guns 32 are mounted on the mounting frame 33. During the spraying process, the position of the spray assembly 3 can be adjusted in time as needed, such as moving the spray assembly 3 to the rear position of the frame 12 to facilitate the loading of the to-be-coated part 11 in front of the frame 12.

[0061] Among them, a dovetail groove can be set on the frame 12, and a dovetail block that cooperates with the dovetail groove can be set on the mounting frame 33. Alternatively, a slider guide module can be set on the frame 12, and then the mounting frame 33 can be installed on the slider.

[0062] In some examples, the spray gun 32 is slidably connected to the mounting frame 33 via a guide structure. When spraying workpieces 11 of different specifications, the spray gun 32 can be moved as needed to adjust the distance between the liquid outlet of the spray gun 32 and the workpiece 11.
