Description

Technical Field

[0001] This utility model relates to the field of automated processing technology, and more specifically, to a car tailgate transfer device and automated processing equipment. Background Technology

[0002] In current manufacturing, the traditional automotive tailgate adhesive application and edging process relies on single-step manual operation, revealing numerous significant drawbacks in actual production. From a production efficiency perspective, this process requires manual loading and unloading, with each operation dependent on manual handling and placement. This time-consuming process significantly extends the production cycle, resulting in a huge gap in capacity compared to modern, efficient production lines. Safety hazards are equally concerning. Automotive tailgate components are typically heavy, and manual handling of these components places a considerable physical burden on workers. Furthermore, accidents such as slips or falls can easily cause serious injuries or fatalities. Utility Model Content

[0003] The technical problem to be solved by this application is that the traditional automobile tailgate spraying and edge-wrapping process has the disadvantages of low manual handling efficiency, high safety hazards and easy damage to the workpiece. In order to overcome the above-mentioned defects of the prior art, this application provides an automobile tailgate transfer device.

[0004] This application provides a car tailgate transfer device, comprising: a support frame, which is erected between a glue spraying station and an edge banding station for supporting the transfer device; a moving mechanism, including a moving frame and a frame drive unit, wherein the moving frame is reciprocally mounted on the support frame via the frame drive unit, and the moving path covers the glue spraying station and the edge banding station; a plurality of gripping mechanisms, which are mounted on the moving frame for gripping the car tailgate; and a plurality of adsorption mechanisms, which are mounted on the moving frame for adsorbing the car tailgate.

[0005] Compared with the prior art, the automobile tailgate transfer device disclosed in this application has the following advantages: by using a support frame to span the glue spraying station and the edge wrapping station, combined with a reciprocating moving mechanism, the automatic transfer of the automobile tailgate between different stations can be realized, replacing traditional manual handling, significantly improving production efficiency and shortening the production cycle; the combined design of the clamping mechanism and the adsorption mechanism can provide dual fixing methods for automobile tailgates of different specifications or surface characteristics, ensuring the stability of the workpiece during the transfer process and avoiding the risk of falling.

[0006] In one possible implementation, the clamping mechanism includes two clamping jaws and a clamping cylinder. The clamping cylinder is mounted on the movable frame, and the two clamping jaws are connected to the clamping output end of the clamping cylinder. Compared with the prior art, the clamping cylinder drives the two clamping jaws to move synchronously, realizing rapid clamping and release of the car tailgate. The operation response is sensitive and suitable for the high-frequency operation requirements of automated production lines.

[0007] In one possible implementation, elastic pads are provided on the opposing clamping surfaces of the two clamping claws. Compared with the prior art, the elastic pads can buffer the clamping force and prevent the hard clamping claws from directly contacting the surface of the car tailgate, thus avoiding scratches, indentations, and other damage. This is especially suitable for metal or composite material tailgates with high requirements for appearance quality. At the same time, it can compensate for workpiece dimensional tolerances or surface curvature, improve clamping compatibility, and reduce the gripping failure rate caused by workpiece differences.

[0008] In one possible implementation, the adsorption mechanism includes a negative pressure suction cup and a suction cup frame. The suction cup frame is mounted on a movable frame, and the negative pressure suction cup is hinged to the suction cup frame and connected to an external air source. Compared with existing technologies, the negative pressure suction cup generates suction force through an external air source, reducing damage to the workpiece. Simultaneously, the suction cup, hinged to the suction cup frame, can adaptively adjust the adsorption direction according to the workpiece surface angle, enhancing adsorption stability. This is particularly suitable for transplanting curved surfaces or irregularly shaped tailgates.

[0009] In one possible implementation, the frame drive unit includes a lateral movement component and a vertical movement component. The lateral movement component includes a transverse frame, a guide rail, a slide, a rack, a drive gear, and a gear drive motor. The rack extends laterally and is fixed to the support frame. The drive gear meshes with the rack and is driven by the gear drive motor, which is mounted on the transverse frame. The guide rail extends laterally and is fixed to the support frame. The slide is slidably disposed on the guide rail and fixedly connected to the transverse frame. Compared with the prior art, the meshing transmission of the drive gear and rack provides a stable driving force. Combined with the guiding effect of the guide rail and slide, it ensures the straightness and positioning accuracy of the moving frame when moving laterally between workstations, avoiding offset errors.

[0010] In one possible implementation, the vertical movement assembly includes a lifting cylinder, a lifting plate, a guide rod, and a guide seat. The lifting cylinder is mounted on the transverse frame, and its lifting end is connected to the lifting plate. The lifting plate is fixed to the moving frame. The guide rod is fixed to the lifting plate and extends vertically, slidingly passing through the guide seat, which is fixed to the transverse frame. Compared with existing technologies, the cylinder-driven lifting action has a fast response, is suitable for high-frequency lifting requirements, and improves production efficiency. Simultaneously, the guide rod and guide seat cooperate to reduce lateral offset during lifting, ensuring the vertical lifting of the moving frame and preventing the tailgate from detaching due to tilting.

[0011] In one possible implementation, a buffer assembly is also included. This assembly comprises a buffer frame, a buffer head, a guide rod, and a spring. The buffer frame is mounted on a movable frame, the guide rod is slidably disposed vertically on the buffer frame, the buffer head is fixed to the bottom end of the guide rod, and the spring is sleeved on the guide rod to absorb the contact impact on the tailgate. Compared to existing technologies, the buffer assembly, when gripping or adsorbing the tailgate, uses spring compression to buffer the contact impact force, avoiding rigid collisions that could cause tailgate deformation or mechanical damage. This flexible contact design improves the equipment's adaptability to tailgates of different sizes or surface conditions and reduces collision noise.

[0012] In one possible implementation, a limiting block is provided at the top of the guide rod to prevent it from detaching from the buffer frame. Compared with the prior art, this prevents the guide rod from completely detaching from the buffer frame under the action of spring force, ensuring the structural integrity and long-term reliability of the buffer assembly.

[0013] This application also provides an automated processing device, including the automobile tailgate transfer device as described above, and a glue spraying machine and an edge banding machine linked with the transfer device. Attached Figure Description

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] See Figures 1 to 5 This application discloses a car tailgate transfer device, including: a support frame 1, a moving mechanism 2, multiple clamping mechanisms 3, and multiple adsorption mechanisms 4; the support frame 1 is installed between the glue spraying station and the edge wrapping station to support the transfer device; the moving mechanism 2 includes a moving frame 23 and a frame drive unit, the moving frame 23 is reciprocally mounted on the support frame 1 through the frame drive unit, and the moving path covers the glue spraying station and the edge wrapping station; the multiple clamping mechanisms 3 are installed on the moving frame 23 to grip the car tailgate; the multiple adsorption mechanisms 4 are installed on the moving frame 23 to adsorb the car tailgate.

[0026] Specifically, the support frame 1 is horizontally spanned across the glue spraying station and the edge wrapping station. It can be fixed to the production line support using a metal frame structure to provide support for the overall device. The moving frame 23 of the moving mechanism 2 is a rectangular metal frame, which is installed on the top of the support frame 1 through the frame drive unit. The moving path of the moving frame 23 covers the area directly above the two stations and can move back and forth between the stations through control system commands. The gripping mechanism 3 and the adsorption mechanism 4 are distributed longitudinally at intervals below the moving frame 23. The number of them can be set according to the size of the car tailgate and are used to grip and adsorb the tailgate respectively to achieve double fixation.

[0027] As can be seen above, the support frame 1 spans the glue spraying station and the edge wrapping station, and is combined with the reciprocating moving mechanism 2, which allows the car tailgate to be automatically transferred between different stations, replacing traditional manual handling, greatly improving production efficiency and shortening the production cycle. Multiple clamping mechanisms 3 and adsorption mechanisms 4 are installed on the moving frame 23. The combination of the two can provide dual fixing methods for car tailgates of different specifications or surface characteristics, ensuring the stability of the workpiece during the transfer process, avoiding the risk of the car tailgate falling, improving the adaptability and reliability of the device to different tailgates, and meeting the needs of efficient and stable operation of automated production lines.

[0028] See also Figure 5 In this embodiment, the clamping mechanism 3 includes two clamping claws 31 and a clamping cylinder 32. The clamping cylinder 32 is mounted on the movable frame 23, and the two clamping claws 31 are connected to the clamping output end of the clamping cylinder 32. Specifically, the clamping cylinder 32 is a double-acting cylinder, which is connected to the bottom surface of the movable frame 23 by bolts. Each end of the piston rod of the cylinder is connected to a clamping claw 31, and the two clamping claws 31 are arranged symmetrically. When the piston rod of the cylinder extends or retracts, the two clamping claws 31 open and close synchronously to clamp or release the edge of the tailgate. For example, after the glue spraying station is completed, the cylinder drives the clamping claws 31 to clamp the tailgate, and the suction mechanism 4 lifts the tailgate and transfers it to the edge-wrapping station.

[0029] In this embodiment, elastic pads 33 are provided on the opposing clamping surfaces of the two clamping claws 31. Specifically, the elastic pads 33 are made of silicone or polyurethane material and are fixed to the inner side of the clamping claws 31 by adhesive or bolts. The surface of the elastic pads 33 is designed with a rough texture to increase friction and prevent the tailgate from sliding, while also buffering the clamping force. The elastic pads 33 can prevent the clamping claws 31 from directly squeezing and causing surface indentations, while also adapting to the slight curvature differences of the tailgate edge, improving clamping compatibility.

[0030] See also Figure 5In this embodiment, the adsorption mechanism 4 includes a negative pressure suction cup 41 and a suction cup frame 42. The suction cup frame 42 is mounted on the movable frame 23, and the negative pressure suction cup 41 is hinged to the suction cup frame 42 and connected to an external air source. Specifically, the suction cup frame 42 is a metal bracket, vertically connected to the bottom surface of the movable frame 23, and the lower end of the bracket is hinged to the negative pressure suction cup 41 via a pin. The negative pressure suction cup 41 is made of rubber and is internally connected to an external vacuum pump or compressed air system via an air pipe. When adsorbing the tailgate, the air source generates negative pressure to make the suction cup adhere to the tailgate surface. The hinged structure allows the suction cup to automatically adjust with the angle of the tailgate surface, ensuring a tight fit between the adsorption surfaces and avoiding adsorption failure due to angle deviation.

[0031] See also Figure 3 and Figure 4In this embodiment, the frame drive unit includes a lateral movement component 21 and a vertical movement component 22. The lateral movement component 21 includes a lateral frame 211, a guide rail 212, a slide block 213, a rack 214, a drive gear 215, and a gear drive motor 216. The rack 214 extends laterally and is fixed on the support frame 1. The drive gear 215 meshes with the rack 214 and is driven by the gear drive motor 216. The gear drive motor 216 is mounted on the lateral frame 211. The guide rail 212 extends laterally and is fixed on the support frame 1. The slide block 213 slides... The vertical moving component 22 is mounted on the guide rail 212 and fixedly connected to the horizontal moving frame 211. The vertical moving component 22 includes a lifting cylinder 221, a lifting plate 222, a guide rod 223 and a guide seat 224. The lifting cylinder 221 is mounted on the horizontal moving frame 211, and the lifting end of the lifting cylinder 221 is connected to the lifting plate 222. The lifting plate 222 is fixed on the moving frame 23. The guide rod 223 is fixed on the lifting plate 222 and extends vertically. The guide rod 223 slides through the guide seat 224, and the guide seat 224 is fixed on the horizontal moving frame 211. Specifically, in the lateral movement assembly 21, two parallel guide rails 212 are fixed to the top of the support frame 1 by bolts, and the slide block 213 is nested in the guide rails 212 and fixedly connected to the lateral movement frame 211 to ensure that the lateral movement frame 211 slides laterally along the guide rails 212; the rack 214 is fixed to one side of the support frame 1 parallel to the guide rails 212, and the drive gear 215 is installed on the output shaft of the gear drive motor 216, and the motor is fixed to the lateral movement frame 211 through the motor mount; when the motor drives the gear 215 to rotate, the gear meshes with the rack 214 to drive the lateral movement frame 211 to move along the guide rails 212, realizing the lateral displacement of the moving frame 23 from the glue spraying station to the edge wrapping station, with high transmission accuracy and smooth operation. The lifting cylinder 221 is vertically installed on the top surface of the transverse frame 211. The lower end of the cylinder piston rod is fixedly connected to the lifting plate 222. The lifting plate 222 is connected to the top surface of the moving frame 23 by bolts. The guide rod 223 is vertically fixed to the bottom surface of the lifting plate 222. The guide seat 224 (such as a linear bearing seat) is fixed on the transverse frame 211. The guide rod 223 passes through the guide seat 224 and can slide up and down. When the cylinder piston rod extends or retracts, the lifting plate 222 drives the moving frame 23 to move up and down. The cooperation between the guide rod 223 and the guide seat 224 restricts lateral and longitudinal offset, ensuring that the moving frame 23 moves vertically. When grabbing the tailgate, the height is accurately positioned to avoid tilting and collision.

[0032] See also Figure 5In this embodiment, the device further includes a buffer assembly 5, which includes a buffer frame 51, a buffer head 52, a guide rod 53, and a spring 54. The buffer frame 51 is mounted on the movable frame 23, the guide rod 53 is slidably mounted on the buffer frame 51, the buffer head 52 is fixed to the bottom end of the guide rod 53, and the spring 54 is sleeved on the guide rod 53 to absorb the contact impact on the tailgate of the car. A limiting block 55 is provided at the top end of the guide rod 53 to prevent the guide rod 53 from falling off the buffer frame 51. Specifically, the buffer frame 51 is a metal bracket fixed to the bottom surface of the movable frame 23; the upper end of the guide rod 53 is slidably connected to the buffer frame 51 via a limiting block 55. The limiting block 55 is a ring-shaped metal part, threadedly connected to the top of the guide rod 53, with a diameter larger than the guide hole diameter of the buffer frame 51, to prevent the guide rod 53 from dislodging when the spring 54 rebounds. The lower end of the guide rod 53 is fixed with a buffer head 52; the spring 54 is sleeved on the outside of the guide rod 53, with its two ends abutting against the buffer frame 51 and the limiting block 55 respectively. When gripping or adsorbing the tailgate, the buffer head 52 contacts the tailgate surface first, and the guide rod 53 compresses the spring 54 to buffer the impact force, avoiding rigid collisions that could cause deformation of the tailgate or damage to the mechanism, which is especially suitable for tailgates made of sensitive composite materials.
