Description

Technical Field

[0001] This utility model relates to the field of automotive exterior panel processing, and in particular to a cleaning and conveying mechanism for automotive exterior panel spraying. Background Technology

[0002] In the pretreatment process before painting automotive exterior panels (such as bumpers and side panels), it is necessary to clean the dust and other contaminants from their surfaces to avoid affecting the quality of the painting. Currently, the cleaning process usually involves workers cleaning the surface of the exterior panels before sending them to the painting station for painting. This is not only inefficient but also prone to causing secondary pollution.

[0003] Traditional cleaning devices often use fixed clamps or single-point clamping mechanisms to hold materials during cleaning. When loading and unloading, manual alignment of the positioning holes is required. When switching to different car model exterior panels, the machine must be stopped to replace the clamping components, which affects the improvement of production efficiency. Therefore, this solution proposes a cleaning and conveying mechanism for automotive exterior panel spraying. Utility Model Content

[0004] This utility model proposes a cleaning and conveying mechanism for automotive exterior panel spraying, which solves the problem that the loading and unloading of workpieces in existing automotive exterior panel cleaning devices is not convenient enough.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cleaning and conveying mechanism for spraying automotive exterior panels includes a base, a rotating shaft rotatably connected to the top of the base, and multiple material holding mechanisms mounted on the outer periphery of the rotating shaft.

[0007] The material-fixing mechanism includes two movable tubes, a fixed plate fixed to the outer periphery of the rotating shaft and a main air pipe, and a connecting pipe for connecting the two movable tubes to the main air pipe and for adjusting the position of the movable tubes. A vacuum pump for extracting air from the main air pipe is installed on the top of the fixed plate, and a suction cup is installed at the other end of the movable tube.

[0008] A main valve is installed on the main air pipe. An adjusting handle is installed at one end of the valve stem of the main valve. A pressure relief pipe is installed on the outer periphery of the main air pipe on the side of the main valve close to the installation pipe. A secondary valve is installed on the pressure relief pipe. One end of the valve stem of the secondary valve is connected to the valve stem of the main valve so as to drive the secondary valve to close and open accordingly when the main valve is opened or closed.

[0009] It also includes a cleaning mechanism installed on top of the base for cleaning dust from the surface of materials on the solidification mechanism.

[0010] The above technical solution not only facilitates the fixing and disassembly of automotive exterior panels during cleaning, but also greatly improves work efficiency and reduces operational difficulty through the setting of multiple material fixing mechanisms.

[0011] As a further improvement to the above solution, a steering motor for driving the rotating shaft is installed on the bottom surface of the base.

[0012] As a further improvement to the above solution, the connecting pipe includes two L-shaped gas distribution pipes and an installation pipe fixed to one end of the main gas pipe. The long ends of the two gas distribution pipes are respectively movably inserted into the inner sides of both ends of the installation pipe, and one end of the two movable pipes is respectively inserted into the inner side of the short ends of the two gas distribution pipes.

[0013] As a further improvement to the above solution, a locking bolt 1 for locking the gas distribution pipe is threadedly connected to the outer periphery of the mounting pipe near its end, and a locking bolt 2 for locking the movable pipe is threadedly connected to the outer periphery of the short end of the gas distribution pipe.

[0014] As a further improvement to the above solution, a mounting plate for supporting the installation pipe is fixed on the top surface of the fixing plate. The mounting plate is sleeved on the outer periphery of the main air pipe and its top surface is fixedly connected to the bottom surface of the installation pipe.

[0015] As a further improvement to the above solution, the cleaning mechanism includes a mounting bracket fixed to the top surface of the base, a nozzle mounted on the mounting bracket, and a blower for supplying air into the nozzle. The mounting bracket is also equipped with a transmission assembly for driving the nozzle to move.

[0016] As a further improvement to the above solution, the mounting bracket includes a support plate and a top plate fixed to the top of the support plate. The bottom surface of the top plate has a mounting groove arranged along its length. The transmission assembly includes a screw rotatably connected in the mounting groove, a moving block threaded around the outer periphery of the screw, and a transmission motor installed at one end of the top plate for driving the screw to rotate. The bottom of the moving block is fixedly connected to the bottom of the nozzle.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. By setting up a material-fixing mechanism, the main valve can be opened while the secondary valve is closed. This creates a negative pressure in the moving tube after the suction cup adheres to the bottom of the material, which can then hold the material in place. At the same time as the main valve is closed, the secondary valve can be automatically opened, thereby restoring the pressure in the moving ring to normal, making it easier for workers to remove the material from the suction cup.

[0019] 2. By setting up a rotating shaft and multiple material fixing mechanisms, continuous production can be achieved, thereby effectively improving production efficiency.

[0020] 3. The cleaning mechanism is designed to use a blower to input a rapid airflow into the nozzle, thereby blowing away dust from the surface of the material and achieving the purpose of cleaning. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example 1:

[0032] Please combine Figure 1 - Figure 6This embodiment of a cleaning and conveying mechanism for automotive exterior panel spraying includes a base 1, a rotating shaft 4 rotatably connected to the top of the base 1, multiple material holding mechanisms 5 mounted on the outer periphery of the rotating shaft 4, and a steering motor 6 for driving the rotating shaft 4 to rotate mounted on the bottom surface of the base 1. The output shaft of the steering motor 6 is connected to the rotating shaft 4 for transmission. The multiple material holding mechanisms facilitate the continuous suction of the material to be cleaned by the material holding mechanisms after the rotating shaft rotates, and then convey it to the cleaning mechanism below for cleaning under the rotation of the rotating shaft 4, thereby effectively improving production efficiency.

[0033] The solidification mechanism 5 includes two movable tubes 506, a fixed plate 501 fixed to the outer periphery of the rotating shaft 4, a main air pipe 502, and connecting pipe fittings for connecting the two movable tubes 506 to the main air pipe 502 and for adjusting the position of the movable tubes 506. A vacuum pump 503 for extracting air from the main air pipe 502 is installed on the top of the fixed plate 501. A suction cup 507 is installed at the other end of the movable tubes 506. The connecting pipe fittings include two L-shaped air distribution pipes 505 and an installation pipe 504 fixed to one end of the main air pipe 502. The long ends of the two air distribution pipes 505 are movably inserted into the inner sides of both ends of the installation pipe 504, and one end of each of the two movable tubes 506 is inserted into the short ends of the two air distribution pipes 505. When the vacuum pump 503 is working, it draws air from the main air pipe 502, the connecting pipe fittings, and the two movable tubes 506 to the main air pipe 502. When the material to be cleaned is pulled out and its bottom surface comes into contact with the suction cups 507 on the two movable tubes 506, a negative pressure is formed in the main air pipe 502, connecting pipe, and the two movable tubes 506, thereby sucking the material tightly onto the top of the suction cups 507, thus achieving the purpose of fixing the material. Depending on the size of the material, the height and horizontal position of the two suction cups 507 can be adjusted. When it is necessary to reduce the distance between the two suction cups 507, the air distribution pipe 505 is moved into the mounting pipe 504. Conversely, when it is necessary to increase the distance between the two suction cups 507, the two air distribution pipes 505 can be pulled out to the outside of the mounting pipe 504. When it is necessary to adjust the height of the suction cups 507, the movable tubes 506 can be moved up and down. This allows for convenient adjustment of the height and position of the suction cups 507 according to the shape or size of the material.

[0034] A main valve 512 is installed on the main air pipe 502. An adjusting handle 514 is installed at one end of the valve stem of the main valve 512. A pressure relief pipe 511 is installed on the outer periphery of the main air pipe 502, near the mounting pipe 504 of the main valve 512. A secondary valve 513 is installed on the pressure relief pipe 511. A driving bevel gear is sleeved on the outer periphery of the valve stem of the main valve 512. A driven bevel gear that meshes with the driving bevel gear is fixed at one end of the valve stem of the secondary valve 513, so that the secondary valve 513 will correspondingly close and open when the main valve 512 opens or closes. When it is necessary to use the suction cup 507 to pick up and fix the material, the valve stem of the main valve 512 is opened by holding the adjusting handle 514 and rotating it. This causes the valve stem of the secondary valve 513 to rotate clockwise, closing the secondary valve 513. This allows outside air to enter the main air pipe 502 through the pressure relief pipe 511. The air in the main air pipe 507 is drawn out, creating a negative pressure, which causes the suction cup 507 to firmly suck up the material. Conversely, when it is necessary to remove the material sucked up by the suction cup 507, the main valve 512 is closed by holding the adjusting handle 514. At this time, the valve stem of the main valve 512 drives the valve stem of the secondary valve 513 to rotate counterclockwise, thus opening the secondary valve 513. Outside air enters the main air pipe 502 through the pressure relief pipe 511, thereby restoring the pressure in the main air pipe 502. The suction cup 507 then releases its grip on the material, allowing the operator to easily remove it.

[0035] In this embodiment, a locking bolt 508 for locking the air distribution pipe 505 is threadedly connected to the outer periphery of the mounting pipe 504 near its end. A locking bolt 509 for locking the movable pipe 506 is threadedly connected to the outer periphery of the short end of the air distribution pipe 505. After the locking bolt 508 is tightened, one end of it abuts against the outer periphery of the air distribution pipe 505, thereby locking the air distribution pipe 505. After the locking bolt 508 is loosened, the air distribution pipe 505 can be moved to adjust the distance between the two suction cups 507. After the locking bolt 509 is tightened, one end of it abuts against the outer periphery of the movable pipe 506, thereby locking the movable pipe 506. After the locking bolt 509 is loosened, the movable pipe 506 can be moved up and down to adjust the height of the suction cup 507.

[0036] The top surface of the fixed plate 501 is fixed with a mounting plate 510 for supporting the mounting pipe 504. The mounting plate 510 is sleeved on the outer periphery of the main air pipe 502 and its top surface is fixed to the bottom surface of the mounting pipe 504. The weight of the material is supported by the fixed plate 501 through the mounting plate 504, thereby avoiding excessive pressure on the main air pipe 502.

[0037] Example 2:

[0038] Combination Figure 1 and Figure 6This embodiment, based on embodiment 1, further improves upon the following: it also includes a cleaning mechanism installed on the top of the base 1 for cleaning dust from the surface of the material on the solidification mechanism 5. The cleaning mechanism includes a mounting frame 2 fixed to the top surface of the base 1, a nozzle 8 mounted on the mounting frame 2, and a blower 3 for supplying air into the nozzle 8. The mounting frame 2 is also equipped with a transmission component for driving the nozzle 8 to move. The air outlet of the blower 3 is connected to the nozzle 8 through a hose. After the blower 3 is started, a strong airflow is sprayed out from the nozzle 8. After the solidification mechanism drives the material to rotate below the nozzle 8, the rotating shaft 4 stops rotating. At this time, the high-speed airflow sprayed out by the nozzle 8 can blow away the dust on the surface of the material, thereby achieving the purpose of cleaning the dust on the surface of the material. When the drive component is running, it can drive the nozzle 8 to move.

[0039] The mounting frame 2 includes a support plate and a top plate fixed to the top of the support plate. The bottom surface of the top plate has a mounting groove 9 arranged along its length. The transmission assembly includes a screw 10 rotatably connected in the mounting groove 9, a moving block threaded onto the outer periphery of the screw 10, and a transmission motor 7 installed at one end of the top plate to drive the screw 10 to rotate. The bottom of the moving block is fixed to the bottom of the nozzle 8. During cleaning, the transmission motor 7 starts. When the transmission motor 7 rotates forward, it drives the screw 10 to rotate forward, thereby driving the moving block and the nozzle 8 to move to the left. Conversely, when the transmission motor 10 rotates in reverse, it can drive the nozzle 8 to move to the right, thereby facilitating the left and right movement of the nozzle 8 and thus cleaning the dust on the surface of the material more thoroughly.

[0040] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
