Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts processing, in particular to an automatic assembly line equipment for automobile tailgate glue spraying and hemming. Background Art

[0002] like Figure 1 The automobile tailgate workpiece 10 shown has an edge with an edge strip 101. In the current manufacturing industry, the traditional automobile tailgate glue spraying and edge binding process adopts a single process manual operation, which exposes many defects that are difficult to ignore in the actual production process.

[0003] From a production efficiency perspective, this process requires multiple people to manually load and unload materials. Each loading and unloading operation relies on manual handling and placement, which is not only time-consuming but also requires the coordination of multiple workers, resulting in significantly longer production cycles and a significant gap in production capacity compared to modern, efficient production lines.

[0004] In terms of quality stability, controlling the amount of glue and determining the hemming position rely heavily on manual experience. Different workers vary in their ability to control the amount of glue. Some may apply too much glue, resulting in waste, while others may not apply enough, impacting bond strength. Furthermore, due to the subjective nature of manual operation, it's difficult to ensure the exact same hemming position for each tailgate, making deviations very likely. These errors accumulate during mass production, leading to inconsistent product quality.

[0005] Safety hazards should not be ignored. Car tailgate components are often heavy, and manual handling of these components places a heavy strain on workers. Furthermore, if a worker makes a mistake, they could easily suffer serious safety accidents, such as injuries.

[0006] From the perspective of resource utilization, since the amount of glue is difficult to accurately control manually, excessive glue spraying often occurs, resulting in serious waste of materials. Summary of the Invention

[0023] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] See also Figures 2 to 7 , the embodiment of the present application discloses an automatic assembly line equipment for gluing and hemming of automobile tailgate, including a material transfer mechanism, a gluing mechanism 2 and an hemming mechanism 3; the material transfer mechanism includes a plurality of handling robots 1, which are used to sequentially transport the processed material 10 from the feed end to the gluing mechanism 2 and the hemming mechanism 3, and then move it out from the discharge end; the gluing mechanism 2 includes a gluing machine frame 21, a gluing robot arm 22, a gluing head 23, a gluing part 24 and a first positioning part 25, the first positioning part 25 is installed on the workbench of the gluing frame 21 and is used to position the processed material Part 10, the glue spraying robot arm 22 is installed on the glue spraying machine frame 21 and is located above the positioning part, the glue spraying head 23 is connected to the action end of the glue spraying robot arm 22, and the glue supply part 24 is installed on the top of the glue spraying machine frame 21 and is connected to the glue spraying head 23 through a pipe; the edge wrapping mechanism 3 includes an edge wrapping machine frame 31, a second positioning part 32 and an edge wrapping device 33, the second positioning part 32 is installed on the workbench of the edge wrapping machine frame 31 and is used to position the processing workpiece 10, and the edge wrapping device 33 is installed on the edge wrapping machine frame 31 and is distributed around the outer peripheral side of the second positioning part 32.

[0025] Among them, the handling robot 1 can adopt a six-axis industrial robot or a SCARA robot, among which the six-axis industrial robot has higher movement flexibility and can adapt to complex three-dimensional space handling needs. Its operating end adopts vacuum adsorption, which has high requirements on the surface quality of the processed material but does not produce mechanical deformation; the glue spraying robot arm 22 of the glue spraying mechanism 2 preferably adopts a multi-joint robot arm driven by a high-precision servo motor, which has high repeatability and ensures the accuracy of the glue spraying path; the glue spraying head 23 can adopt a quantitative injection valve or a screw metering pump, among which the quantitative injection valve can realize precise control of the glue amount, and the error range is highly controllable; the glue supply part 24 can be configured as a pressure tank glue supply system or a gear pump glue supply system, and the pressure tank glue supply system is suitable for the stable delivery of high-viscosity glue.

[0026] As can be seen from the above, the material transfer mechanism enables the automated flow of processed parts, avoiding the inefficiencies and safety hazards of manual handling. The glue spraying mechanism 2 uses a robotic arm to precisely control the glue spraying path and amount, eliminating the inconsistencies of manual operation. The hemming mechanism 3 uses mechanical positioning and an automated hemming device 33 to ensure accurate and consistent hemming. Through the coordinated cooperation of these various mechanisms, the entire system achieves fully automated production of the automobile tailgate glue hemming process, significantly improving production efficiency and product quality stability.

[0027] Continue to see Figure 4 In this embodiment, the first positioning portion 25 includes a first seating seat 251 and a first support frame 252. The first seating seat 251 is fixed to the workbench of the glue spraying machine frame 21 via the first support frame 252. The first seating seat 251 is provided with a first positioning groove 253 with an upward opening. The first positioning groove 253 matches the shape of the workpiece 10. Specifically, the first seating seat 251 is used to support the workpiece 10. Its structural design must match the shape of the workpiece 10 to ensure positioning accuracy. The first support frame 252 can be fixed to the workbench of the glue spraying machine frame 21 by welding or bolting. It must have sufficient rigidity to resist vibration during processing. The rigid fixing method of the first support frame 252 avoids the displacement phenomenon common in traditional clamps, ensuring that the position of the workpiece remains stable during glue spraying. The opening direction of the first positioning groove 253 is set to face upward to facilitate the placement and positioning of the workpiece 10. The shape of the first positioning groove 253 must be designed according to the specific contour of the workpiece 10. Common implementation methods include using contouring or mold forming processes to produce the positioning groove. That is, this structure realizes the precise positioning of the workpiece 10, eliminates the problem of glue spraying position deviation caused by manual placement error, and significantly improves the consistency and reliability of the glue spraying process.

[0028] In this embodiment, a plurality of material fixing parts 26 are provided on the glue spraying machine frame 21, and the plurality of material fixing parts 26 are distributed around the outer side of the first placement seat 251. The material fixing parts 26 include a fixing frame 261, a swinging cylinder 262, a swing arm 263 and a fixed pressure block 264. The fixing frame 261 is fixed on the workbench of the glue spraying machine frame 21, the swinging cylinder 262 is fixed on the fixing frame 261, the swinging end of the swinging cylinder 262 is connected to the swing arm 263, and the fixed pressure block 264 is connected to the end of the swing arm 263 away from the swing cylinder 262, so as to press the processed material 10 into the first positioning groove 253. Specifically, the fixing frame 261 can be fixed to the workbench of the glue spraying machine frame 21 by welding or bolting. The swinging cylinder 262 preferably has a rotation angle of 90°-180° and is controlled by a solenoid valve to achieve swinging. The swing arm 263 is connected to the swinging cylinder 262 by a flange connection or a coupling connection. The fixed pressure block 264 is connected to the swing arm 263 by a quick-release structure such as a threaded fastening. In other words, through the coordinated action of the surrounding material fixing parts 26, the swinging cylinder 262 drives the swing arm 263 to drive the fixed pressure block 264 downward, thereby achieving multi-point positioning and fixation of the workpiece 10. The fixed pressure block 264 can be made of rubber, which can ensure sufficient clamping force while avoiding damage to the surface of the workpiece 10. Compared with manual fixing methods, this mechanical positioning structure can ensure the consistency of the clamping position each time, effectively solving the positioning deviation problem caused by manual operation in traditional processes; at the same time, the automated fixing method eliminates the safety hazards of manual handling, so that the material will not be displaced during the spraying operation, ensuring the accuracy of the spraying trajectory.

[0029] Continue to see Figure 6 In this embodiment, the second positioning portion 32 includes a second seating seat 321 and a second support frame 322. The second seating seat 321 is fixed to the workbench of the hemming machine frame 31 via the second support frame 322. The second seating seat 321 is provided with a second positioning groove 323 with an upward opening. The second positioning groove 323 matches the shape of the workpiece 10. Specifically, the second seating seat 321 is used to support the workpiece 10, and its structural design must be compatible with the shape of the workpiece 10. The second support frame 322 can be fixed to the workbench of the hemming machine frame 31 by welding or bolting to ensure support stability. The opening direction of the second positioning groove 323 is set to face upward to facilitate the placement and positioning of the workpiece 10. The shape of the second positioning groove 323 must be designed according to the contour of the specific workpiece 10. Common implementation methods include using profiling or mold forming processes to produce the positioning groove. This solution replaces manual positioning with mechanical positioning, significantly improving the processing accuracy and consistency of the hemming process while reducing the labor intensity of operators; in actual application, this technical solution can ensure the accuracy of the hemming position, thereby improving product quality stability.

[0030] In this embodiment, a material fixing mechanism 34 is provided on the edging frame 31, and the material fixing mechanism 34 includes a mounting plate 341, a lifter 342 and a fixed pressure rod 343. The mounting plate 341 is vertically lifted and connected to the edging frame 31 through the lifter 342, and the fixed pressure rod 343 is fixed on the mounting plate 341. The fixed pressure rod 343 is located above the second placement seat 321 to press the processed material 10 into the second positioning groove 323; the lifter 342 includes a rack 3421, a driving gear 3422 and a gear driver 3423. The gear driver 3423 is installed on the top of the edging frame 31, and the driving gear 3422 is connected to the output end of the gear driver 3423. The rack 3421 is fixed on the mounting plate 341 and meshes with the driving gear 3422. The rack 3421 is extended vertically. Specifically, the workpiece securing mechanism 34 uses a lifter 342 to achieve vertical lifting and lowering of the mounting plate 341. The mounting plate 341 serves as a support platform for the fixed pressure rods 343, whose lifting and lowering travel is precisely controlled by limit switches or position sensors. Buffer pads can be provided at the ends of the fixed pressure rods 343 to prevent damage to the workpiece surface, and the number of fixed pressure rods 343 can be arranged to match the size of the workpiece. That is, after the workpiece is initially positioned by the second positioning groove 323, the lifter 342 drives the mounting plate 341 downward, causing the fixed pressure rods 343 to apply a vertical downward pressure to the workpiece, ensuring its stability during the hemming process. Compared to manual operation, this mechanism achieves precise application of constant pressure, avoiding uneven pressure due to fluctuations in manpower.

[0031] In this embodiment, a sliding guide assembly 35 is provided on the hemming frame 31. The sliding guide assembly 35 includes a guide rail 351 and a slider 352. The guide rail 351 is fixed vertically to the hemming frame 31, and the slider 352 is fixed to the mounting plate 341 and slides with the guide rail 351. Specifically, the sliding guide assembly 35 is used to guide the lifting and lowering movement of the mounting plate 341, ensuring that the mounting plate 341 remains stable during the lifting process. The guide rail 351 can be a linear guide rail 351 or a cylindrical guide rail 351, and can be made of high-strength steel or aluminum alloy. The slider 352 is internally equipped with balls or rollers to reduce frictional resistance between the slider 352 and the guide rail 351. The guide rail 351 is fixed to the column of the hemming frame 31 by bolts, and the slider 352 is connected to the mounting plate 341 by screws. That is, the cooperation between the guide rail 351 and the slider 352 makes the lifting movement smoother, thereby ensuring that the fixed pressure rod 343 can accurately press the workpiece 10 into the second positioning groove 323; compared with the lifting mechanism without a guide, this structure significantly improves the positioning accuracy and operational stability, and avoids the edge position deviation caused by the offset of the mounting plate 341; at the same time, the rigid support of the sliding guide assembly 35 also reduces the load of the lifter 342, thereby extending the service life of the equipment.

[0032] Continue to see Figure 6 and Figure 7 In this embodiment, the hemming device 33 includes a pressing head 331, a pressing head lifting cylinder 332, a pressing head transverse movement cylinder 333 and a clamping assembly. The pressing head 331 is connected to the lifting end of the pressing head lifting cylinder 332, the pressing head lifting cylinder 332 is connected to the transverse movement end of the pressing head transverse movement cylinder 333, and the pressing head transverse movement cylinder 333 is installed on the workbench of the hemming frame 31. The clamping assembly is installed on the mounting plate 341 and is used to clamp the hemming strip 101 of the workpiece 10 on the pressing head 331 so that the pressing head 331 flips the hemming strip 101; the clamping assembly includes a clamping block 334 and a clamping block transverse movement cylinder 335, the clamping block transverse movement cylinder 335 is fixed on the mounting plate 341, the clamping block 334 is connected to the transverse movement end of the clamping block transverse movement cylinder 335, and the clamping block 334 is used to clamp the hemming strip 101 tightly against the pressing head 331. Specifically, servo cylinders are used for the ram lift cylinder 332, the ram transverse cylinder 333, and the clamp transverse cylinder 335 to achieve precise position control. This automated hemming process is achieved through mechanized clamping and flipping. Compared to manual hemming, this device ensures consistent hemming position and flipping force for each workpiece, avoiding quality fluctuations caused by manual operation.
