Description

Technical Field

[0001] The present invention relates to the field of automotive parts processing equipment, and specifically to a gluing and curing system for automotive exterior covering parts. Background Art

[0002] Automotive covering parts are an important part of the overall framework of an automobile. Plastic covering parts generally require good appearance and sufficient strength. Therefore, most plastic covering parts are formed by bonding inner and outer plates. The bonding of the inner and outer plates requires flame treatment first. Through a strong oxidation flame, the plastic surface is oxidized, thereby improving the bonding characteristics of the plastic. Then, glue is applied to the inner wall of the outer plate by a glue gun to form a glue line. Then, the inner and outer plates are pressed and bonded together through the glue line to form a whole. During this process, residues are likely to be generated at the mouth of the glue gun, resulting in glue liquid accumulation or unevenness on the product.

[0003] At the same time, most of the existing covering part gluing processes are processed by a robot arm grabbing the corresponding covering parts and processing tools. Each process is relatively independent, and it is very difficult to perform multiple processes on the same equipment simultaneously, resulting in low work efficiency.

[0004] Immediately after gluing and pressing, curing treatment is required. During this process, because gluing and curing are not carried out on the same equipment, and because the curing is not yet complete, when moving the product after gluing and pressing, problems such as displacement may occur, resulting in quality problems such as glue leakage and misalignment.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figures 1 to 5, the present invention provides a technical solution: a glue coating and curing system for automotive exterior trim covers, including a support frame 1, a cover plate 2, a glue coating box 3, and a switching structure 4. The support frame 1 is used to support the cover plate 2 and the automotive exterior trim covers. The cover plate 2 is arranged on the support frame 1 and on the glue coating box 3. The glue coating box 3 is used for coating glue and curing on the automotive exterior trim covers. The switching structure 4 is arranged inside the glue coating box 3 and is used to switch the glue coating and curing functions of the glue coating box 3. Both ends of the glue coating box 3 are connected to a hot air blower 5, and the hot air blower 5 is installed on the side of the support frame 1. The delivery of the glue liquid is realized through the glue coating box 3, and the curing after glue coating is realized through the linkage effect of the hot air blower 5 and the glue coating box 3;

[0032] Both ends of the glue coating box 3 are provided with cylinders 6, and the cylinders 6 are fixedly installed on the support frame 1. The cylinders 6 are used to drive the switching structure 4 to switch between the glue coating and curing functions;

[0033] The switching structure 4 includes two groups, namely a switching plate one 41 and a switching plate two 42. The output shafts of the cylinders 6 are respectively connected to the backs of the switching plate one 41 and the switching plate two 42. The switching plate one 41 and the switching plate two 42 realize the function of switching the glue coating and curing processes through the drive of the cylinders 6, and the combination of the glue coating and curing functions is realized through the structural linkage of the switching plate one and the switching plate two.

[0034] In this embodiment, the support frame 1 includes an upper support plate 11 and a lower support plate 12. The upper support plate 11 includes two symmetrically arranged groups, and the glue coating box 3 is arranged between the two groups of upper support plates 11. The lower support plate 12 is arranged directly below the glue coating box 3. The upper support plate 11 is used to install the cover plate, and the lower support plate 12 is used to place the covers to be coated with glue and, after pressing the fittings on the surface of the coated covers, perform the curing process again.

[0035] In this embodiment, the cover plate 2 is fixedly installed on the upper support plate 11 through a number of support bodies 21 arranged at the four corners. The support bodies 21 are symmetrically arranged on the two groups of upper support plates 11, and the support bodies 11 are used to position and fixedly install the cover plate 2.

[0036] In this embodiment, both ends of the glue coating box 3 are provided with connecting frames 31. The upper ends of the connecting frames 31 are detachably connected to the cover plate 2, the lower ends of the connecting frames 31 are communicated with the glue coating box 3, the connecting frames 31 are connected to the hot air blower 5, and the hot air flow generated by the hot air blower 5 enters the air collecting box through a pipeline to be mixed evenly. The air collecting box is communicated with the inside of the connecting frame, enters the connecting frame 31 through the air collecting box, and finally enters the glue coating box 3.

[0037] In this embodiment, a glue discharge pipe 32 is provided at the lower end of the glue application tank 3, and air outlet holes 35 are provided on the bottom surface of the glue application tank 3. The glue liquid entering the glue application tank 3 will be discharged through the glue discharge pipe 32. The glue discharge pipe 32 is connected to external glue application components such as nozzles and painting brushes for glue application. The provided air outlet holes 35 can discharge the hot air entering the glue application tank 3 onto the applied glue liquid for curing.

[0038] In this embodiment, a reflux groove 43 is provided at the lower ends of the switching plate one 41 and the switching plate two 42. The reflux groove 43 is located directly above the glue discharge pipe 32. The reflux groove 43 can suck back the glue liquid entering the glue discharge pipe 32 through the action of negative pressure to prevent the glue liquid from remaining on the glue application component.

[0039] In this embodiment, a drainage groove 44 is provided at the upper ends of the switching plate one 41 and the switching plate two 42. The drainage groove 44 is a "V"-shaped groove. The drainage groove 44 is located directly below the glue inlet pipe 45. The glue inlet pipe 45 is installed on the cover plate 2. The drainage groove 44 facilitates the concentration of the glue liquid and discharges the concentrated glue liquid through the glue discharge pipe 32. The glue inlet pipe 45 is connected to an external glue supply device.

[0040] In this embodiment, symmetric sealing ends 46 are provided at the tops of the switching plate one 41 and the switching plate two 42. The bottoms of the switching plate one 41 and the switching plate two 42 are connected to a traction plate 47 through a sealing plate 49. The traction plate 47 is connected to the output shaft of the cylinder 6 through a connecting rod 48. The sealing plate 49 can block the air outlet holes 35. The sealing ends 46 and the sealing plate 49 can divide the glue application tank 3 into two parts, one for the flow of glue liquid and the other for the storage of hot air flow.

[0041] In this embodiment, a piston plate 421 is provided inside the second switching plate 42. A piston rod 422 is provided on the piston plate 421. The other end of the piston plate 422 is fixedly connected to the first switching plate 41. The piston plate 421 can move back and forth inside the piston chamber 423. The bottom of the piston chamber 423 is connected to the return groove 43 through the recovery channel 424. The top of the piston chamber 423 is connected to the diversion groove 44 through the confluence channel 425. An elastic sealing cover 426 is provided at the mouth of the confluence channel 425. When gluing is required, the first switching plate 41 and the second switching plate 42 move away from each other under the action of the cylinder 6, generating a channel for the glue liquid to flow from the diversion groove 44 to the glue discharge pipe 32. The glue liquid is discharged through the glue discharge pipe 32 for gluing. At this time, the piston plate 421 is pulled by the piston rod 422 to the side closest to the first switching plate 41 inside the piston chamber 423. At the same time, the air outlet hole 35 will be blocked by the sealing plate 49. After gluing is completed, the cylinder 6 is used to push the first switching plate 41 and the second switching plate 42 to move towards each other for a certain distance, and the glue liquid in the glue discharge pipe 32 is recovered through the recovery channel 424 to avoid residue. At this time, the sealing plate 49 still covers the air outlet hole 35. After gluing is completed and the fitting is pressed on the covering part, the cylinder 6 continuously drives the first switching plate 41 and the second switching plate 42 to move towards each other until they are completely fitted. At this time, it can prevent the glue liquid from flowing down again into the glue discharge pipe 32. At the same time, the sealing plate 49 no longer blocks the air outlet hole 35, and hot air starts to be used for curing. At the same time, the provided return channel can recover the glue liquid flowing into the glue discharge pipe 32 and the glue liquid located in the nozzle and the coating brush as much as possible, preventing the glue liquid at these positions from being affected by the hot air and curing. When the first switching plate 41 and the second switching plate 42 move away from each other again for gluing next time, due to the extrusion of the piston plate 421, the glue liquid in the piston chamber 423 will squeeze open the elastic sealing cover 426 through the confluence channel 425 and rejoin the glue liquid in the diversion groove 44.

[0042] Based on the above, the glue application box and the provided switching structure of the invention can meet the two processes of glue application and curing on the same device, without the need to be separated on different devices or production lines, and can avoid quality problems caused by moving products during process switching; the switching structure provided by the invention can also realize the glue liquid residue on components such as the glue application nozzle during switching, and recover the excess glue liquid when switching to the curing function, realizing the linkage of switching and solving the problem of glue liquid residue, and achieving multiple effects through one structure.

[0043] As is known by common technical knowledge, the present invention can be implemented by other embodiments that do not deviate from its spiritual essence or necessary features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not the only ones. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
