[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figure 1-5 As shown, this utility model provides an automatic air blowing cleaning device for automotive parts, including a frame 1, a loading and unloading device 2, a picking and unloading device 3 and an air blowing cleaning device 4 installed on the frame 1.

[0036] in,

[0037] The material handling device 3 includes a robotic arm 32 connected to the base 31 and a clamping mechanism 33 installed at the free end of the robotic arm 32. The robotic arm 32 drives the clamping mechanism 33 to automatically reciprocate between the loading / unloading device 2 and the air cleaning device 4.

[0038] The air-blowing cleaning device 4 includes a cleaning cylinder 41 mounted on a frame 1, an upper annular air knife 42 and a lower annular air knife 43 arranged vertically along the inner wall of the cleaning cylinder 41, and a plurality of spray guns 44 evenly distributed circumferentially along the cylinder wall of the cleaning cylinder 41. The upper end of the cleaning cylinder 41 is provided with a feed port. A cleaning chamber for the workpiece is formed between the upper annular air knife 42 and the lower annular air knife 43. The plurality of spray guns 44 are arranged on the periphery of the cleaning chamber. The air blowing directions of the upper annular air knife 42 and the lower annular air knife 43 are opposite and radially inward, respectively corresponding to the upper and lower surfaces of the workpiece.

[0039] The working principle and beneficial effects of the above embodiments are as follows:

[0040] The loading and unloading device 2 of this utility model is responsible for carrying the automotive parts (workpieces) to be cleaned and placing the cleaned workpieces, so as to realize the automatic supply and collection of workpieces.

[0041] The robotic arm 32 of the loading and unloading device 3 drives the clamping mechanism 33 to move, first clamping the workpiece to be cleaned from the loading and unloading device 2, and then transferring it to the cleaning chamber of the cleaning cylinder 41 of the air blowing cleaning device 4; after cleaning, the robotic arm 32 drives the clamping mechanism 33 to transfer the cleaned workpiece back to the loading and unloading device 2, completing one cycle.

[0042] After the workpiece enters the cleaning chamber, the upper annular air knife 42 blows air radially inward to clean the upper surface of the workpiece; the lower annular air knife 43 also blows air radially inward to clean the lower surface of the workpiece; at the same time, several spray guns 44 evenly distributed along the circumference of the cleaning cylinder 41 spray airflow into the cleaning chamber to clean the workpiece from the circumference. The three work together to achieve all-round air cleaning of the workpiece and remove surface impurities, dust and other contaminants.

[0043] This utility model has a high degree of automation. Through the cooperation of the loading and unloading device 2, the picking and placing device 3 and the air blowing cleaning device 4, the workpieces are automatically transferred, picked up and placed and cleaned, reducing manual intervention and improving production efficiency.

[0044] The air-blowing cleaning device 4 of this utility model provides comprehensive cleaning without any blind spots. The upper annular air knife 42 and the lower annular air knife 43 are used to clean the upper and lower surfaces of the workpiece respectively, while the circumferential spray gun 44 cleans from the side, forming a three-dimensional cleaning system that ensures that all parts of the workpiece are effectively cleaned and improves the cleaning quality.

[0045] In one embodiment,

[0046] Two sets of spray guns 44 are arranged vertically along the wall of the cleaning cylinder 41. The two sets of spray guns 44 are opposite to each other and extend into the cleaning chamber at an angle, respectively corresponding to the periphery of the workpiece.

[0047] Two sets of spray guns 44 form an intersecting inclined airflow, spraying from different heights and angles around the workpiece. Together with the upper annular air knife 42 and the lower annular air knife 43, they clean the upper and lower surfaces, further covering the vertical surfaces, corners, and any grooves around the workpiece.

[0048] In one embodiment,

[0049] For example Figure 3 As shown, the end of the robotic arm 32 is configured as a ball screw capable of linear and rotary motion. The clamping mechanism 33 is installed at the lower end of the ball screw, and a cover plate 34 matching the feed inlet of the cleaning cylinder 41 is also installed on the ball screw.

[0050] When loading and unloading materials, the ball screw extends downwards, allowing the clamping mechanism 33 to approach the loading and unloading device 2 to pick up the parts. During the cleaning stage, the ball screw drives the clamping mechanism 33 and the workpiece on it to extend into the cleaning chamber until the cover plate 34 contacts the cleaning cylinder 41, closing the cleaning chamber. At this time, the ball screw drives the workpiece to rotate, which, together with the upper annular air knife 42, the lower annular air knife 43 and the spray gun 44, makes the removal of impurities more thorough.

[0051] During the cleaning stage, the cover plate 34 and the inlet of the cleaning cylinder 41 are sealed together to form a relatively closed space in the cleaning chamber, preventing airflow from leaking out of the inlet, increasing the airflow pressure in the cleaning chamber, enhancing the flushing force of the upper annular air knife 42, the lower annular air knife 43 and the spray gun 44, preventing impurities from overflowing with the airflow, and reducing pollution to the external environment of the equipment.

[0052] In one embodiment,

[0053] A sealing gasket is installed at the lower end of the cover plate 34. During the workpiece cleaning stage, the cover plate 34 rotates with the workpiece, and the sealing gasket reduces the rigid wear between the cover plate 34 and the cleaning cylinder 41.

[0054] In one embodiment,

[0055] like Figure 6 As shown, a discharge port is provided at the lower end of the cleaning cylinder 41, and the discharge port is connected to the filter 5 installed in the frame 1.

[0056] When the workpiece is washed by the upper annular air knife 42, the lower annular air knife 43, and the upper and lower sets of spray guns 44 in the cleaning chamber, the stripped impurities settle downward with the airflow. The airflow carrying the impurities enters the filter 5 through the discharge port at the lower end of the cleaning cylinder 41. The filter 5 filters the airflow and traps the impurities. The purified airflow can be directly discharged or recycled.

[0057] In one embodiment,

[0058] like Figure 7 As shown, the above-mentioned loading and unloading device 2 includes a synchronous belt 21 installed on the frame 1 and capable of rotating autonomously. The synchronous belt 21 is provided with a loading position and a unloading position. The loading position is provided with a guide mechanism 22 and an upper limit plate 23, and the unloading position is provided with a lower limit plate 24.

[0059] The upper limit plate 23 and the lower limit plate 24 are both provided with V-shaped grooves facing the movement direction of the synchronous belt 21 to limit the displacement of the workpiece; the guide mechanism 22 includes a limiting baffle arranged along the length direction of the synchronous belt 21. The limiting baffle is adjustablely installed on both sides of the width direction of the synchronous belt 21 to guide the workpiece to move in the correct posture.

[0060] The workpiece to be cleaned is placed at the loading position of the synchronous belt 21. The guide mechanism 22 arranged along the length of the synchronous belt 21 guides the workpiece. By adjusting the spacing of the limit baffles, it adapts to workpieces of different widths and forces the workpiece to move along the preset path to ensure that it is conveyed to the upper limit plate 23 in the correct posture. The V-groove of the upper limit plate 23 holds the workpiece to ensure that the clamping mechanism 33 of the robotic arm 32 can accurately grasp the workpiece.

[0061] After the cleaned workpiece is placed back to the unloading position of the synchronous belt 21 by the robotic arm, it moves with the synchronous belt 21 to the lower limit plate 24. The V-groove of the lower limit plate 24 also holds the workpiece, and then the workpiece is picked up manually or by a robotic arm to complete the entire loading and unloading process.

[0062] In one embodiment,

[0063] The aforementioned clamping mechanism 33 includes a pneumatic gripper installed at the lower end of the ball screw. The pneumatic gripper is an internal support type, and a rubber pad is installed on the contact surface between the pneumatic gripper and the workpiece.

[0064] When the robotic arm 32 drives the pneumatic gripper to approach the workpiece to be gripped, the gripping fingers of the pneumatic gripper retract and extend into the inner hole of the workpiece. After the gripping fingers are ventilated, they expand outward and fit tightly against the inner wall of the workpiece through the internal support force, thus achieving a stable gripping of the workpiece. The rubber pad on the contact surface between the pneumatic gripper and the workpiece deforms as the gripping fingers expand, filling the gap between the gripping fingers and the inner wall of the workpiece, enhancing the friction, and at the same time avoiding direct rigid contact between the gripping fingers and the workpiece.

[0065] In one embodiment,

[0066] The upper end of the cleaning cylinder 41 is provided with a cover, and the inlet is provided on the cover. The cover is configured as a double-opening structure.

[0067] When the upper annular air knife 42, the lower annular air knife 43, or the spray gun 44 malfunctions such as blockage, air leakage, or angle deviation, the two split covers can be fully opened to both sides, allowing operators to directly observe the condition of the internal components and perform cleaning, replacement, or repair.

[0068] In summary:

[0069] This utility model discloses an automatic air-blowing cleaning device for automotive parts. Through the cooperation of a loading and unloading device, a picking and placing device, and an air-blowing cleaning device, it realizes the automatic transfer, picking and placing, and cleaning of workpieces, reducing manual intervention and improving production efficiency.

[0070] This utility model's air-blowing cleaning device provides comprehensive cleaning without any blind spots. The upper and lower annular air knives target the upper and lower surfaces of the workpiece respectively, while the circumferential spray gun cleans from the side, forming a three-dimensional cleaning effect. This ensures that all parts of the workpiece are effectively cleaned, thus improving the cleaning quality.

[0071] The arrangement of the annular air knife and circumferential spray gun in this invention can adapt to automotive parts of different sizes, eliminating the need for frequent adjustments to equipment parameters and enhancing the equipment's versatility.
