Description

Technical Field

[0001] The utility model relates to the technical field of automobile door panel spraying, in particular to an automobile door panel spraying machine. Background Art

[0002] Car door panel spraying usually refers to the process of surface coating of car door interior panels. This process is not only related to the aesthetics of the car door, but also involves durability and protection.

[0003] Among them, in the process of spraying automobile door panels, primer spraying as a pre-spraying process has an important influence on the corrosion protection of the entire automobile door panel and the adhesion of the subsequent paint layer.

[0004] At present, when spraying the primer of automobile door panels, the main method used is a spray device for automobile door panel processing, as disclosed in the patent document with patent authorization announcement number CN220425681U, whose main structure is as follows: the bottom end of the connecting frame is rotatably connected to the second connecting block, the bottom end of the second connecting block is fixedly connected to a universal wheel, the inside of the second connecting blocks on the left and right sides are slidably connected to two limit rods, the right end of the base is fixedly connected to a motor, the top right side of the base is fixedly connected to a bracket, the bottom end of the bracket is fixedly connected to a spray mechanism, and the middle part of the top of the base is fixedly connected to a support plate.

DETAILED DESCRIPTION

[0028] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 5 as shown in .

[0029] Embodiment 1: A car door panel spraying machine comprises two C-shaped rails suspended and fixed on the top of a paint spraying room, the two C-shaped rails are spaced apart and symmetrically arranged, a hanging slide rail is fixedly installed on the top of the paint spraying room above the center of the two C-shaped rails, a plurality of T-shaped slides spaced apart along the length direction thereof are slidably engaged in the hanging slide rails, a traveling mechanism is fixedly installed at the bottom of each T-shaped slide, both ends of the traveling mechanism are respectively mounted in the C-shaped rail grooves of the corresponding C-shaped rails, a door panel hanger is fixedly installed at the bottom of each traveling mechanism, door panel spraying units are respectively fixedly installed on the ground below the two C-shaped rails, and the two door panel spraying units cooperate to complete the spraying operation on the surfaces of both sides of the car door panels transported along the C-shaped rails.

[0030] The automobile door panel spraying machine in this design adopts a hoisting method when fixing the automobile door panel as a whole, and can rely on the corresponding walking mechanism to complete the movement or positioning along the length direction of the C-type track, thereby ensuring that the hoisted automobile door panel can pass through the corresponding door panel spraying unit at a set speed, thereby achieving the purpose of spraying primer on the corresponding surface.

[0031] In any of the above schemes, it is preferred that the two door panel spraying units are relatively staggered.

[0032] The relatively staggered door panel spraying units can ensure that they do not affect each other during operation, ensure the normal spraying of each door panel spraying unit and the residual paint mist splashed by the spraying will not be sprayed onto another door panel spraying unit, thereby ensuring the relative cleanliness of the door panel spraying units.

[0033] In any of the above schemes, it is preferred that the walking mechanism includes a hanging frame fixed to the bottom of the T-shaped slide, and a dual-output shaft motor is fixedly installed in the installation cavity of the hanging frame, and the motor shafts on both sides of the dual-output shaft motor are movably extended to the outside of the hanging frame and are respectively coaxially fixed with a connecting shaft, and the ends of the two connecting shafts respectively extend into the C-shaped rail grooves on the corresponding sides, and walking wheels coaxially arranged therewith are fixedly installed on the outer side walls of the ends of the connecting shafts in each of the C-shaped rail grooves, and the bottom of the walking wheels abuts against the bottom of the C-shaped rail groove.

[0034] The power component of the walking mechanism as a whole is a dual-output shaft motor. When the dual-output shaft motor is working, its entire motor housing is fixedly installed inside the hanging frame to achieve anti-rotation positioning, and the entire hanging frame is slidably clamped in the corresponding sliding groove of the hanging slide rail by a T-shaped slide seat. When the motor shaft of the dual-output shaft motor is running, it will drive the corresponding connecting shaft to rotate, thereby driving the walking wheel to rotate. When the walking wheel is in the running state, it can drive the entire walking mechanism to move linearly along the length direction of the C-shaped rail groove, thereby controlling the displacement of the corresponding door panel hanger and the automobile door panel clamped and fixed thereunder.

[0035] In any of the above schemes, it is preferred that the door panel hanger includes a positioning frame fixedly installed at the bottom center of the corresponding hanging frame, two hanging columns are arranged at intervals at the bottom of the positioning frame, the bottom of the two hanging columns are fixed to the top of a horizontally arranged connecting seat, two U-shaped frames are arranged at intervals and symmetrically on both sides of the bottom of the connecting seat, a horizontal electric cylinder is fixedly installed in the U-shaped cavity of each U-shaped frame, the ends of the piston rods of the two horizontal electric cylinders are movably extended to the space below the middle of the connecting seat, and a clamping block is fixedly installed at the end of the piston rod of each horizontal electric cylinder, and the two oppositely arranged clamping blocks cooperate to achieve clamping and positioning of the top of the automobile door panel to be sprayed.

[0036] When the door panel hanger clamps the car door panel, it mainly uses the extension and retraction of the horizontal electric cylinders on both sides to drive the corresponding clamping blocks to clamp the top two sides of the car door panel located between the two clamping blocks, and controls the clamping force of the horizontal electric cylinder to ensure that the car door panel will not fall off.

[0037] Embodiment 2: Compared with Embodiment 1, this embodiment is different in that it also includes the following technical features:

[0038] The door panel spraying unit includes a vertically arranged L-shaped mounting seat, and a plurality of nozzles are fixedly installed at intervals from top to bottom on the vertical section of the L-shaped mounting seat, and each of the nozzles is connected to an external paint spraying pump through a pipeline. A plurality of lifting electric cylinders are arranged at intervals along the length direction at the bottom of the horizontal section of the L-shaped mounting seat, and the bottom of each lifting electric cylinder is fixedly installed on the ground, and each lifting electric cylinder maintains synchronous movement.

[0039] The door panel spraying unit as a whole relies on the synchronous lifting of each lifting electric cylinder to drive the corresponding nozzle on the L-shaped mounting seat to lift and lower, so as to complete the surface spraying of primer on the car door panel in different height directions, and effectively cooperate with the operation of the walking mechanism to drive the horizontal movement of the car door panel to complete horizontal spraying, ensuring the comprehensiveness of the car door panel surface spraying.

[0040] In any of the above schemes, preferably, a waste paint collection box is fixedly installed on the ground between the two door panel spraying units, and the waste paint collection box extends along the length direction of the C-type track.

[0041] The waste paint collection box provided here can realize the rapid collection of waste paint generated during the spraying process.

[0042] In any of the above schemes, it is preferred that a receiving panel is provided above the waste paint collection box, the middle part of the receiving panel is recessed downward to form a material guiding section, and a long material guiding groove is provided at the bottom of the material guiding section, which is arranged from top to bottom, and the long material guiding groove is located directly above the waste paint collection box.

[0043] The paint falling on the receiving panel can be continuously gathered toward the material guide section, and finally falls into the corresponding paint waste collection box through the material guide long groove.

[0044] In any of the above solutions, preferably, the T-shaped slide seat is made of brass and the bottom is set to be a polished smooth surface.

[0045] The brass T-shaped slide can achieve self-lubrication and reduce running friction, ensuring the smoothness of the traveling mechanism during movement.

[0046] Specific working principle: The automobile door panel spraying machine uses a hoisting method to fix the automobile door panel during operation, and can rely on the corresponding walking mechanism to complete the travel or positioning along the length direction of the C-type track.

[0047] It ensures that the hoisted automobile door panel can pass through the corresponding door panel spraying unit at the set speed, thereby achieving the purpose of spraying primer on the corresponding surface.

[0048] When passing the door panel spraying unit on the corresponding side, the moving speed of the car door panel is controlled to match the spraying speed. During the specific spraying, the door panel spraying unit as a whole relies on the synchronous lifting of each lifting electric cylinder to drive the corresponding nozzle on the L-shaped mounting seat to lift and lower, thereby completing the primer spraying on the surface of the car door panel in different height directions, and effectively cooperating with the operation of the walking mechanism to drive the horizontal movement of the car door panel to complete the horizontal spraying, thereby ensuring the comprehensiveness of the surface spraying of the car door panel.

[0049] The paint waste collection box during the spraying process can realize the rapid collection of waste paint generated during the spraying process.

[0050] From the above, it can be seen that the automobile door panel spraying machine can quickly complete the hanging, conveying and shifting of multiple door panels to be sprayed, can cooperate with the walking mechanism to complete the required walking or positioning along the length direction of the corresponding C-shaped track, and cooperate with the door panel spraying units on both sides to quickly complete the double-sided spraying of each automobile door panel; during the spraying process, the lifting and lowering control of the lifting electric cylinder in the door panel spraying unit can be controlled to adjust the height position of each nozzle installed thereon, and at the same time, the horizontal adjustment can be achieved under the action of the walking mechanism, so that the surface of the automobile door panel can be sprayed comprehensively during the spraying process, thereby improving the spraying effect.

[0051] In addition, the hanging method adopted in this design can effectively expose both sides of the car door panel, effectively ensuring that the spraying of both sides can be completed without changing the surface during spraying, reducing the number of position changes during the spraying of the car door panel primer and improving the spraying efficiency; it can be seen that when the car door panel is hoisted, the relative tightening of the horizontal electric cylinders arranged on both sides can better ensure the clamping effect when clamping the car door panel, and effectively prevent it from falling off and positioning.

[0052] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model. For technicians in this technical field, any replacement improvements or changes made to the implementation methods of the utility model fall within the protection scope of the utility model.
