Description

Technical Field

[0001] This invention relates to the technical field of automobile tailgate processing, and specifically to a painting equipment for an automobile lightweight all-plastic tailgate processing system. Background Technology

[0002] During the manufacturing process of lightweight all-plastic tailgates for automobiles, multiple tailgates need to be transported sequentially to the paint booth via a chain conveyor line for surface painting. However, in existing technologies, when transporting tailgates via chain conveyor lines, the tailgates are often directly suspended on a hanger. Due to the long transport distance, the tailgates may sway during transport, causing damage to the suspension points and resulting in subsequent quality issues. Summary of the Invention

[0003] The purpose of this invention is to provide a painting equipment for a lightweight all-plastic tailgate processing system for automobiles, so as to overcome the above-mentioned defects in the prior art.

[0004] A painting equipment for a lightweight all-plastic tailgate processing system for automobiles includes a chain conveyor line passing through the painting chamber, with several hooks evenly distributed along the chain conveyor line, and each hook is equipped with a lifting device for lifting the tailgate of the automobile.

[0005] The lifting device is equipped with a limiting mechanism to prevent the tailgate of the car from swaying;

[0006] The lifting device is also equipped with a locking mechanism for locking the limiting mechanism.

[0007] Preferably, the lifting device includes a lifting ring, a support plate, a crossbar, and a spring. The lifting ring is mounted on a fixed rod at the top of the support plate. The crossbar is slidably connected to a sliding rod inside the support plate. The spring is fitted onto the sliding rod. Both ends of the crossbar are respectively provided with fixed hooks that hook into through holes on the tailgate of the vehicle.

[0008] Preferably, the limiting mechanism includes a guide post one, a limiting block and a spring two. The guide post one is slidably connected to the support plate and has a sliding groove that is slidably connected to the sliding rod. The limiting block is located at the end of the support plate. The spring two is sleeved on the guide post one and located between the limiting block and the support plate. The guide post one is provided with a baffle plate one.

[0009] Preferably, the locking mechanism includes a locking plate, a third spring, a second guide post, and a fourth spring. The locking plate is slidably connected to a connecting rod on the side of the support plate and has a second inclined surface at its upper end. A second baffle is provided at the top of the connecting rod. The third spring is sleeved on the connecting rod. The second guide post is slidably connected to the locking plate and has a pressing block at its inner end. The pressing block has a third inclined surface. The fourth spring is sleeved on the second guide post. A third baffle is provided at the outer end of the second guide post. The driving rod on the crossbar extends through a strip groove on the support plate. The support plate has driving blocks on both sides of the strip groove, and each driving block has a fourth inclined surface that cooperates with the third inclined surface.

[0010] Preferably, the guide post is a cuboid structure.

[0011] Preferably, the limiting block is provided with an inclined surface that mates with the mounting groove of the car tailgate.

[0012] Preferably, the end of the guide post is provided with a handle.

[0013] Preferably, the connecting rod has an "L" shaped structure.

[0014] Preferably, the second guide post has a cuboid structure.

[0015] A method for using a painting equipment for a lightweight all-plastic tailgate processing system for automobiles, comprising the above-mentioned painting equipment for a lightweight all-plastic tailgate processing system for automobiles, characterized by the following steps:

[0016] S1. Place the tailgate of the car onto the fixed hooks on both sides of the crossbar through the two through holes on it;

[0017] S2. The tailgate of the car moves the crossbar downward along the slide bar. The drive rod on the crossbar moves the pressing block and the locking plate downward along the connecting rod. The locking plate disengages from the slide groove of the guide post one. The limiting block is inserted into the mounting groove on the tailgate of the car under the elastic force of the spring two.

[0018] S3. When the pressing block contacts the driving block on the side of the support plate, it moves toward the locking plate under the pressure of the driving block, thereby disengaging the pressing block from the driving rod. Under the action of the three spring forces, the locking plate moves up and is located at the end of the guide post.

[0019] S4. Hook the car tailgate onto the hook on the chain conveyor line using the hanging ring at the top of the fixing rod;

[0020] S5. The chain conveyor line moves the car tailgate into the paint booth, where the paint spraying components inside the paint booth spray the car tailgate.

[0021] The present invention has the following advantages:

[0022] In use, this invention involves suspending the tailgate of a car using a lifting device. As the tailgate moves downward, the locking plate of the locking mechanism is unlocked, allowing the limiting block of the limiting mechanism to insert into the mounting groove of the tailgate under the action of spring two. The limiting block presses the tailgate firmly, ensuring that the tailgate is stably placed on the fixed hook of the crossbar. This prevents the tailgate from shaking during its transport to the paint booth via the chain conveyor line, thus avoiding damage to the suspension points of the tailgate.

[0045] Detailed implementation methods and principles:

[0046] S1. Place the tailgate 7 on the fixing hooks 47 on both sides of the crossbar 44 through the two through holes 71 on it.

[0047] S2, the car tailgate 7 drives the crossbar 44 to move downward along the slide bar 45. The spring 46 on the slide bar 45 is compressed. During the downward movement of the slide bar 45, the pressing block 65 and the locking plate 61 are driven to move downward along the connecting rod 62 through the drive rod 67 on its side. The locking plate 61 is disengaged from the slide groove 511 of the guide post 51. The spring 63 is compressed. The limiting block 52 is inserted into the mounting groove 72 on the car tailgate 7 under the elastic force of the spring 53 on the guide post 51.

[0048] S3. When the locking plate 61 moves down, when the pressing block 65 contacts the driving block 68 on the side of the support plate 42, it moves towards the locking plate 61 under the pressing of the driving block 68, thereby causing the pressing block 65 to disengage from the driving rod 67. Under the elastic force of the spring 63, the locking plate 61 moves up and is located at the end of the guide post 51, thereby completing the limiting of the car tailgate 7.

[0049] S4. The tailgate 7 of the car is hung on the hook 3 of the chain conveyor line 2 by the hanging ring 41 at the top of the fixing rod 43;

[0050] S5, the chain conveyor 2 drives the car tailgate 7 to the paint booth 1, and the car tailgate 7 is painted by the paint spraying components in the paint booth 1.

[0051] In summary, the present invention uses the lifting device 4 to suspend the tailgate 7 of the car. When the tailgate 7 moves down, the locking plate 61 of the locking mechanism 6 is unlocked, so that the limiting block 52 of the limiting mechanism 5 is inserted into the mounting groove 72 of the tailgate 7 under the action of the second spring 53. The limiting block 52 presses the tailgate 7, so that the tailgate 7 is stably placed on the fixing hook 47 of the crossbar 44, preventing the tailgate 7 from shaking during the process of being transported to the paint booth 1 on the chain conveyor line 2, which would damage the suspension point of the tailgate 7.

[0052] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the present invention and technical solution to other situations without modification, are all within the protection scope of the present invention.
