Description

Technical Field

[0001] This utility model relates to the field of cleaning machine technology, specifically a robotic arm device for an automatic cleaning machine. Background Technology

[0002] Automatic cleaning machines are complete sets of equipment integrating key technologies such as pumps, valves, high-pressure water jets, mechanical structures, conveying, and automation, as well as auxiliary technologies such as sealing, ventilation, heat exchange, cleaning fluid filtration, oil removal, and chip removal. They generally consist of several major systems including transmission, cleaning, filtration, drying, oil removal, slag discharge, and electrical control. Automatic cleaning machines are widely used to clean contaminants generated or introduced into workpieces during manufacturing, assembly, and use. To facilitate quick and convenient handling of cleaned parts, automatic cleaning machines typically incorporate robotic arms for movement. Existing robotic arm structures generally use either motor-driven chain transmission or pneumatic drive. Chain transmission speeds fluctuate and cannot maintain a constant instantaneous transmission ratio, resulting in unstable operation. Pneumatic drives, compared to motor drives, offer slightly lower positioning accuracy.

[0003] To address the technical problems of unstable operation and inaccurate positioning of the robotic arm in traditional automatic cleaning machines, this utility model proposes a robotic arm device for automatic cleaning machines to solve the aforementioned technical problems.

[0025] The moving mechanism includes a moving frame 4 placed horizontally and slidably mounted on a vertical guide rail 1, a lead screw 7 vertically connected to one side of the moving frame 4, and a servo motor 8 drivenly connected to the upper end of the lead screw 7.

[0026] The second moving mechanism includes a second lead screw 9 rotatably mounted on the first moving frame 4, a second servo motor 10 driven and connected to one end of the second lead screw 9, and slide rails 6 fixedly mounted on both sides of the first moving frame 4. The second lead screw 9 is provided with a second nut seat 12, which is fixedly connected to the first connecting arm 2 and slidably connected to the slide rail 6.

[0027] The connecting arm 2 includes a movable frame 22 that is slidably connected to the slide rail 6, a connecting rod 21 that is horizontally fixed at the upper end of the movable frame 22, a slider 13 that is fixedly installed on the lower inner side of the movable frame 22, the slider 13 that is slidably connected to the slide rail 6, and the movable frame 22 that is connected to the nut seat 12.

[0028] The connecting arm 2 3 includes a movable frame 3 32 that is slidably connected to the slide rail 6, and a connecting rod 2 31 that is horizontally fixed at the upper end of the movable frame 3 32. A slider 3 14 is fixedly installed on the lower inner side of the movable frame 3 32. The slider 3 14 is slidably connected to the slide rail 6. One end of the connecting rod 1 21 and one end of the connecting rod 2 31 are respectively connected to the cleaning basket by bolts.

[0029] Connecting rod 1 (21) and connecting rod 2 (31) are arranged in parallel.

[0030] A nut seat 11 is provided on the lead screw 7, and the nut seat 11 is fixedly connected to the lower part of one side of the movable frame 4.

[0031] The cleaning basket clamp is positioned between connecting rod 21 and connecting rod 31.

[0032] The specific working process of this utility model:

[0033] This utility model is a robotic arm device for an automatic cleaning machine. The entire device needs to be fixed above the cleaning tank of the automatic cleaning machine. Specifically, the vertical guide rail 1, servo motor 8 and lead screw 7 are fixed on the automatic cleaning machine so that the moving mechanism can control the moving frame 4 to move on the vertical guide rail 1.

[0034] When this utility model is in operation, the cleaning basket is connected to connecting rod 21 and connecting rod 31. Then the robotic arm device is started, the servo motor 8 rotates, and the lead screw 7 rotates. The nut seat 11 set on the lead screw 7 moves upward under the drive of the lead screw 7. At the same time, the movable frame 4 fixedly connected to the nut seat 11 moves upward together with the nut seat 11 under the limiting guidance of the slider 5 and the vertical guide rail 1.

[0035] After the movable frame 4 reaches the set height, the servo motor 8 stops rotating. At the same time, the servo motor 10 rotates, driving the lead screw 9 to move. The nut seat 12 on the lead screw 9 slides horizontally to the left under the drive of the lead screw 9. The movable frame 22, which is fixedly connected to the nut seat 12, also slides horizontally to the left. The connecting rod 21, which is fixedly installed on the movable frame 22, slides horizontally to the left along with the movable frame 22. Since one end of the connecting rod 21 and the connecting rod 22 are connected to the cleaning basket, and the cleaning basket is rigid, the movement of the connecting rod 21 will also drive the connecting rod 31 and the movable frame 32 to move, thereby realizing the synchronous movement of the connecting arm 2 and the connecting arm 3.

[0036] After connecting arms 1 and 2 transport the cleaning basket to the set position, servo motor 1 and 8 are activated, driving lead screw 1 and nut seat 11, moving frame 1 and connecting arms 1 and 2 together to move downward in a straight line, sending the cleaning basket into the cleaning tank, and then starting to clean the workpiece.

[0037] After the workpiece is cleaned, servo motor 8 actuates, driving lead screw 7, nut seat 11, moving frame 4, connecting arm 2, and connecting arm 3 to move upward in a straight line. Once the cleaning basket has been raised to the set height, servo motor 8 stops rotating. Simultaneously, servo motor 10 rotates, driving lead screw 9. Nut seat 12, mounted on lead screw 9, slides horizontally to the right under the drive of lead screw 9. At the same time, connecting arms 2 and 3, mounted on moving frame 4, slide horizontally to the right. After lead screw 9 reaches its set stroke, servo motor 10 stops rotating, and servo motor 8 drives lead screw 7 to reset nut seat 11, moving frame 4, connecting arm 2, and connecting arm 3 downward. The above steps are repeated to clean different batches of workpieces.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
