Description

Technical Field

[0001] The present invention relates to the technical field of automobile plastic part conveying, and in particular to an automobile plastic part conveying device. Background Art

[0002] As a crucial component of industrial automated conveying systems, suspension conveyor chains play a key role in automotive manufacturing thanks to their unique space utilization advantages and efficient transmission performance. This system utilizes specialized suspension rails and customized slings to secure workpieces in mid-air, enabling continuous, controlled conveyance. The application of suspension conveyor chains in automotive plastic parts spraying lines fully demonstrates their technological advantages and industrial value.

[0003] Suspension conveyor chains typically consist of a track system, a traction chain, a drive unit, and a sling. The track system can be flexibly designed to suit the workshop layout, whether linear, circular, or curved. It is secured to the workshop ceiling via brackets, effectively avoiding floor space occupation. The traction chain, carrying the sling, circulates along the track, with precisely adjustable transmission speed and tempo to perfectly match the operating rhythm of the spray equipment. The sling is custom-designed based on the shape of the automotive plastic part, ensuring that the workpiece maintains the optimal spraying position during transport.

[0004] Currently, in actual production, when plastic parts are directly suspended from conveyor chain hangers, they are prone to shaking during transportation. This shaking can easily lead to uneven spraying, affecting the appearance and protective performance of the finished product. Secondly, to improve the comprehensiveness of spraying, production lines are often equipped with rotating structures to rotate plastic parts during transportation. However, since the hanging conveyor chain hanger needs to contact the surface of the plastic part to maintain the suspension state, the contact area between the two inevitably forms a blind spot for spraying. These unsprayed areas not only weaken the overall protective ability of the coating, but also require additional manual re-spraying processes, which not only increases the workload but also reduces production efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a conveying device for automobile plastic parts, which, on the basis of ensuring the stability of plastic parts conveying, specifically solves the blind spot problem in suspension spraying, thereby improving production quality and efficiency.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a conveying device for automobile plastic parts, comprising a hanging conveyor chain, wherein the hanging conveyor chain is supported on the ground by multiple brackets, and the hanging conveyor chain is provided with multiple hangers for hanging automobile plastic parts, wherein the hangers include hooks, and the holes of the automobile plastic parts are hung on the hooks, and the hooks are provided with fixing parts for fixing the automobile plastic parts.

[0007] A conveying assembly is provided at the bottom of the hanging conveyor chain. The conveying assembly includes a shell. Three groups of conveying parts are provided inside the shell to facilitate spraying of blind areas of automobile plastic parts.

[0008] Preferably, the hook comprises a vertical portion, a horizontal portion and a hook portion, the horizontal portion is fixed between the vertical portion and the hook portion, and the hole of the automobile plastic part is hung on the horizontal portion.

[0009] Preferably, the fixing part is arranged outside the horizontal part of the hook, and the fixing part includes a plurality of arc-shaped clamps, one end of the arc-shaped clamp is rotatably connected to the outer wall of the horizontal part, and the other end of the arc-shaped clamp is connected to the outer wall of the horizontal part through a spring; the hole of the automobile plastic part is located outside the arc-shaped clamp, and the arc-shaped clamp fixes the hole of the automobile plastic part through the elastic force of the spring.

[0010] Preferably, the vertical portion, horizontal portion, and hook portion of the hook are all hollow and interconnected, with a valve fixed to the vertical portion. Multiple spray holes are defined on the outer walls of the horizontal portion and hook portion, with the spray holes on the horizontal portion located on one side of the fixing member. Spray holes are holes or structures used to atomize liquids such as water, paint, and pharmaceuticals into fine droplets. The core principle is that fluid mechanics causes the liquid to be subjected to shear, impact, or centrifugal force as it passes through the hole, breaking it into tiny droplets (i.e., atomization). Spray holes are widely used in spraying, humidification, dust removal, agricultural plant protection, and other fields.

[0011] Preferably, the hanging conveyor chain is provided with a feeding assembly for conveying paint to the hook, and the feeding assembly includes an annular tube arranged on the outside of the hanging conveyor chain track and a hollow rotating plate arranged on the top of the bracket; annular limit plates distributed up and down are fixed to the outside of the hanging conveyor chain track, and a slide groove is formed between the two annular limit plates, and the annular tube is slidably arranged in the slide groove, and the top of each hook is connected to the annular tube through a connecting tube; the hollow rotating plate is rotatably connected to the bracket, and the hollow rotating plate and the annular tube are connected through multiple conveying pipes.

[0012] Preferably, a support frame is provided on the top of the hollow turntable, and the top of the support frame is fixed to a fixed object through a bracket. A feed pipe is fixed through the support frame, and the bottom end of the feed pipe is rotatably connected to the top of the hollow turntable, and the feed pipe is connected to the inside of the hollow turntable, and the top end of the feed pipe is connected to the paint supply pipeline; the paint enters the hook through the feed pipe, hollow turntable, conveying pipe, and connecting pipe and is then sprayed out through the spray hole.

[0013] Preferably, a channel is provided at the top of the shell for the hanger to pass through. When the hanger carries the automobile plastic parts into the shell, one group of conveying parts is arranged at the bottom of the hanger, and at the same time, this group of conveying parts is arranged at the bottom end of the automobile plastic parts; the other two groups of conveying parts are arranged at the front and rear sides of the hook, and at the same time, these two groups of conveying parts are both arranged at the top end of the automobile plastic parts.

[0014] Preferably, the conveying member includes a mounting seat, the inner wall of the mounting seat is rotatably provided with two rollers, the outer walls of the two rollers are wrapped around the same conveyor belt, and the outer wall of the conveyor belt is fixed with multiple limit blocks; at least one lifting drive member is fixed on the side of the mounting seat away from the automobile plastic part, which is used to drive the mounting seat to rise and fall so that the conveyor belt contacts the automobile plastic part.

[0015] Preferably, when the hanger carries the automobile plastic parts into the shell, the automobile plastic parts leave the fixing parts and are outside the spray holes, and the paint sprayed from the spray holes sprays the holes of the automobile plastic parts; and a heater for drying the paint in the holes is fixed in the shell.

[0016] Preferably, a spraying device is provided at the bottom of the hanging conveyor chain, and the spraying device is provided on one side of the conveying component. The hanger carries the automobile plastic parts into the spraying device for spraying and drying, and then enters the conveying component for spraying and drying the blind area.

[0017] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0018] 1. The holes of automotive plastic parts are suspended on the horizontal part of the hook and conveyed to the spraying device for spraying and drying. At this time, the blind area (inner wall of the hole) where the hook contacts the plastic part is not sprayed. The plastic part then enters the conveying assembly, causing the contact point between the hole and the hook to shift during the conveying process. The plastic part is pulled forward by the hook, while the hole is separated from the hook and is located outside the spray hole on the hook. The spray hole sprays the paint in a targeted and uniform manner on the blind area, and then efficiently dries it, achieving full coating coverage of the plastic part. This solves the problem of contact areas being unable to be sprayed in traditional hanging conveying, and improves production quality and efficiency.

[0019] 2. When automotive plastic parts are hung on the hook and enter the spraying device for spraying, the fixing parts on the hook support the inner wall of the hole of the plastic parts to fix the plastic parts. When the plastic parts enter the conveying assembly, the conveying parts distributed at the upper and lower ends of the plastic parts maintain the stability of the plastic parts to prevent the plastic parts from shaking when hanging, thereby avoiding poor spraying effects caused by shaking of the plastic parts during the spraying process and improving production quality.

[0020] At the same time, when the plastic parts are removed from the conveying assembly after spraying, the fixing parts are separated from the plastic parts and no longer fix the plastic parts, making it easier for personnel to remove the plastic parts. BRIEF DESCRIPTION OF THE DRAWINGS

The suspension conveyor chain 1 is a common industrial transmission device, and its structure is not described in detail in this article.

[0040] The hanging conveyor chain 1 is provided with a plurality of hangers 3 for hanging automobile plastic parts, specifically, Figure 3-Figure 4 As shown, the hanger 3 includes a hook 31, and the hook 31 includes a vertical portion 311, a horizontal portion 312 and a hook portion 313. The horizontal portion 312 is fixed between the vertical portion 311 and the hook portion 313, and the holes of the automobile plastic parts are suspended on the horizontal portion 312, and a fixing part 32 for fixing the automobile plastic parts is provided on the hook 31.

[0041] like Figure 4 As shown, the fixing member 32 is arranged outside the horizontal part 312 of the hook 31, and the fixing member 32 includes a plurality of arc-shaped clamping plates 321, one end of the arc-shaped clamping plate 321 is rotatably connected to the outer wall of the horizontal part 312, and the other end of the arc-shaped clamping plate 321 is connected to the outer wall of the horizontal part 312 through a spring 322; when the hole of the automobile plastic part is located outside the arc-shaped clamping plate 321, the arc-shaped clamping plate 321 fixes the hole of the automobile plastic part through the elastic force of the spring 322.

[0042] like Figure 1 As shown, a spraying device 10 is provided at the bottom of the hanging conveyor chain 1. The hanger 3 carries the automobile plastic parts into the spraying device 10 for spraying and drying. The spraying device 10 adopts an existing spraying device, such as the spraying device with publication number CN218360037U, and can be dried by heating after spraying. The spraying and drying of automobile plastic parts are existing common technologies and will not be further elaborated here.

[0043] like Figure 1 、 Figure 5 、 Figure 6 and Figure 7 As shown, a conveying assembly 4 is provided at the bottom of the hanging conveyor chain 1, and the spraying device 10 is provided on one side of the conveying assembly 4. The hanger 3 carries the automobile plastic parts out of the spraying device 10 and then enters the conveying assembly 4. The conveying assembly 4 includes a shell 41, and a channel is provided at the top of the shell 41 to facilitate the passage of the hanger 3, and a heater for drying the paint in the hole is fixed in the shell 41. The heater is fixed at a suitable position in the shell 41, such as the inner wall or the inner top of the shell 41.

[0044] Three groups of conveying parts 42 are provided inside the shell 41. When the hanger 3 carries the automobile plastic parts into the shell 41, one group of conveying parts 42 is provided at the bottom of the hanger 3, and at the same time, this group of conveying parts 42 is provided at the bottom end of the automobile plastic parts. The other two groups of conveying parts 42 are provided at the front and rear sides of the hook 31, and at the same time, these two groups of conveying parts 42 are provided at the top end of the automobile plastic parts.

[0045] Specifically, the conveying member 42 includes a mounting seat 421, and two rollers 422 are rotatably provided on the inner wall of the mounting seat 421. The outer walls of the two rollers 422 are wrapped with the same conveyor belt 423. The conveyor belt 423 is made of a material with good elasticity, such as natural rubber NR, ethylene propylene rubber EPDM, polyurethane rubber PU, etc., and a plurality of limit blocks 424 are fixed on the outer wall of the conveyor belt 423.

[0046] When the plastic part enters the conveying assembly 4, the contact point between the hole of the plastic part and the hook 31 is transferred, that is, the plastic part is separated from the fixing part 32, and the plastic part is clamped by the upper and lower conveyor belts 423 and pulled forward by the hook 313. The hole of the plastic part does not contact the horizontal part 312 of the hook 31.

[0047] At least one lifting drive component 425 is fixed on the side of the mounting base 421 away from the automotive plastic parts. The lifting drive component 425 can be an electric cylinder, an electric push rod, etc., which is used to drive the mounting base 421 to rise and fall so that the conveyor belt 423 can contact automotive plastic parts of different sizes and can fix automotive plastic parts of different sizes to keep the plastic parts in their current state.

[0048] Then, if Figure 1-Figure 4 、 Figure 8-10 As shown, the vertical portion 311, the horizontal portion 312 and the hook portion 313 of the hook 31 are all hollow and connected in sequence, and a valve 34 is fixed on the vertical portion 311. The valve 34 is preferably an electric valve that can be electrically controlled. The valves 34 located inside the shell 41 are all open, and the electric valves located outside the shell 41 are all closed. The electric valves are controlled by the control system of the conveying device and will not be further elaborated here.

[0049] The outer walls of the horizontal portion 312 and the hook portion 313 are both provided with a plurality of spray holes, and the spray holes on the horizontal portion 312 are provided on one side of the fixing member 32 .

[0050] The hanging conveyor chain 1 is provided with a feeding assembly for conveying paint to the hook 31, and the feeding assembly includes an annular tube 5 arranged outside the track of the hanging conveyor chain 1 and a hollow rotating plate 6 arranged on the top of the bracket 2; annular limit plates 11 distributed up and down are fixed to the outside of the track of the hanging conveyor chain 1, and a slide groove is formed between the two annular limit plates 11, and the annular tube 5 is slidably arranged in the slide groove, and the top of each hook 31 is connected to the annular tube 5 through a connecting tube 33; the hollow rotating plate 6 is rotatably connected to the bracket 2, and the hollow rotating plate 6 and the annular tube 5 are connected through multiple conveying pipes 7.

[0051] A support frame 9 is provided on the top of the hollow rotating plate 6, and the top of the support frame 9 is fixed to a fixed object through a bracket, such as a ceiling. A feed pipe 8 is fixed through the support frame 9, and the bottom end of the feed pipe 8 is rotatably connected to the top of the hollow rotating plate 6 through a sealed bearing, and the feed pipe 8 is connected to the inside of the hollow rotating plate 6. The top of the feed pipe 8 is connected to the paint supply pipeline, and the paint enters the hook 31 through the feed pipe 8, the hollow rotating plate 6, the delivery pipe 7, and the connecting pipe 33 and is then sprayed out through the spray hole.

[0052] When the hanger 3 moves with the suspension conveyor chain 1, the connecting pipe 33 is driven to move, thereby driving the annular pipe 5 to rotate in the slide groove, and then driving the conveying pipe 7 and the hollow rotating plate 6 to rotate. The connecting pipe 33, the annular pipe 5 and the conveying pipe 7 are all hoses, and the conveying pipe 7 is preferably a corrugated pipe that can be arbitrarily expanded and bent.

[0053] Working principle of the present invention:

[0054] The hole of the automobile plastic part is hung on the horizontal portion 312 of the hook 31, and the plastic part is moved toward the fixing member 32, so that the fixing member 32 enters the hole of the plastic part. The arc-shaped clamping plate 321 of the fixing member 32 is supported inside the hole by the spring 322, thereby fixing the plastic part, improving the stability of the movement of the plastic part and subsequent spraying, and ensuring the spraying quality. At the same time, the contact area between the fixing member 32 and the plastic part is called the blind area, that is, the inner wall of the hole, and the paint is not sprayed in the blind area.

[0055] Then, the plastic parts enter the spraying device 10 along the hanging conveyor chain 1 for spraying and drying, and then enter the conveying assembly 4. The lifting drive part 425 of the conveying part 42 adjusts the distance between the upper conveying part 42 and the lower conveying part 42 in advance. When the plastic parts enter the shell 41, the hook 31 moves between the channel of the shell 41 and the two groups of conveying parts 42 on the upper layer, and the plastic parts enter between the upper conveyor belt 423 and the lower conveyor belt 423, and the two layers of conveyor belts 423 clamp the plastic parts. At this time, the hanger 3 continues to move forward and the plastic parts do not move, then the fixing part 32 moves out of the hole in the plastic part, and then the hook part 313 of the hook 31 contacts the plastic part. The hook 31 continues to move so that the hook part 313 drives the plastic parts to continue moving forward. When the plastic parts move, they drive the limit block 424 on the conveyor belt 423 to move, thereby driving the conveyor belt 423 to rotate. That is, the contact point between the hole of the plastic part and the hook 31 is transferred. The plastic part is clamped by the two layers of conveyor belts 423 to maintain the current state and is pulled forward by the hook 313. The hole of the plastic part does not contact the horizontal part 312 of the hook 31. The spray hole on the hook 31 is located inside the hole. Figure 5 and Figure 6 As shown, at the same time, the plastic parts are continuously transported by the advancing hook 313 and the rotating conveyor belt 423;

[0056] At the same time, the valve 34 on the hanger 3 entering the shell 41 is opened, and the paint supply pipeline pumps the paint into the hollow rotating plate 6 through the feed pipe 8. The paint then passes through the delivery pipe 7, the annular pipe 5, the connecting pipe 33, and the vertical part 311 into the horizontal part 312 and the hook part 313. The paint is evenly sprayed on the holes through the spray holes, that is, the blind area is sprayed, and the comprehensive spraying of the plastic parts is improved;

[0057] Then the heater installed in the shell 41 heats the air inside the shell 41. At the same time, when the plastic part moves forward, the hot air passes through the holes, and the coating sprayed in the blind area is efficiently dried, avoiding incomplete drying due to poor airflow inside the holes, thereby improving the drying efficiency. Moreover, the plastic part maintains a stable posture during transportation and movement, and the holes are completely exposed to the hot air. Combined with the immediate drying after spraying through the spray hole, the risk of coating sagging is reduced, and the qualified rate of finished products is improved.

[0058] Subsequently, the hanger 3 carries the plastic part out of the housing 41. After the plastic part leaves the conveying part 42, the conveying part 42 is suspended on the horizontal part 312 of the hook 31 and is located on one side of the fixing part 32. At this time, the fixing part 32 does not fix the plastic part, making it easy for people to remove the plastic part.

[0059] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
