Description

Technical Field

[0001] This utility model relates to the field of spray cleaning technology, and in particular to a double rotary lifting machine used for spray cleaning. Background Technology

[0002] In the entire spraying process, besides the core spraying operation itself, there are also cleaning activities to ensure coating quality and process stability. For example, before spraying, contaminants (oil, rust, dust, water, old coatings, etc.) on the substrate surface need to be removed to ensure good adhesion of the coating to the product surface and guarantee its performance. After spraying, the coating appearance needs to be perfected by wiping, and static electricity on the surface needs to be eliminated by using an electrostatic fan to prevent dust from being attracted during subsequent processing.

[0003] In the existing post-coating cleaning stage, the traditional method is to install an electrostatic fan on the conveyor line to eliminate static electricity from the workpieces on the production line. However, because the airflow coverage is fixed and the workpiece posture cannot be adjusted, static charge residue remains on the workpiece surface.

[0004] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a double rotary lifting machine for spray cleaning, comprising a frame, wherein a lifting mechanism is provided on the frame, the lifting mechanism comprising a lifting plate that can be slidably mounted on the frame and a lifting cylinder mounted on the frame, wherein the telescopic shaft of the lifting cylinder is fixedly connected to the lifting plate.

[0007] The lifting plate is equipped with a rotating mechanism, which includes a rotary motor mounted on the lifting plate, a rotating shaft connected to the output end of the rotary motor, and a workpiece positioning plate fixed to the top of the rotating shaft.

[0008] As a further embodiment of this utility model: the upper end of the workpiece positioning plate is provided with a plurality of positioning posts.

[0009] As a further embodiment of this utility model: sliding guide rails are provided on both sides inside the frame, and guide sleeves that slide in cooperation with the sliding guide rails are provided on both sides of the lifting plate.

[0010] As a further embodiment of this utility model: a mounting bracket located at the lower end of the lifting plate is provided between the sliding guide rails on both sides, and the lifting cylinder is mounted on the mounting bracket.

[0011] As a further embodiment of this utility model: two rotary motors and two workpiece positioning plates are provided, and they are distributed on both sides of the edge of the lifting plate.

[0012] As a further embodiment of this utility model: the rotary motor is installed at the lower end of the lifting plate, and the rotating shaft passes through and extends to the upper end of the lifting plate and is fixedly connected to the workpiece positioning plate.

[0013] As a further embodiment of this utility model, the positioning post has a conical structure.

[0014] Compared with existing technologies, the beneficial effects of this technical solution are as follows: the lifting plate is lifted vertically by the telescopic shaft of the lifting cylinder. During the lifting process, the rotating mechanism is driven to align the workpiece positioning plate with the workpiece and lift the workpiece off the production line. Then, the rotary motor starts running and drives the workpiece positioning plate and the workpiece to rotate through the rotating shaft. The rotation of the workpiece allows the cleaning equipment to reach all areas of the workpiece without dead angles, ensuring that there are no missed cleaning areas on the workpiece surface, thereby improving the cleaning effect and cleaning efficiency.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A double rotary lifting machine for spray cleaning includes a frame 1, a lifting mechanism 2 is provided on the frame 1, the lifting mechanism 2 includes a lifting plate 21 that can be slidably mounted on the frame 1 and a lifting cylinder 22 mounted on the frame 1, and the telescopic shaft of the lifting cylinder 22 is fixedly connected to the lifting plate 21.

[0025] The lifting plate 21 is provided with a rotating mechanism 3, which includes a rotating motor 31 installed on the lifting plate 21, a rotating shaft 32 connected to the output end of the rotating motor 31, and a workpiece positioning plate 33 fixed to the top of the rotating shaft 32.

[0026] During implementation, the frame 1 is installed at the lower end of the conveyor production line. When the workpiece moves above the frame 1, the production line stops conveying the workpiece. Then, the lifting cylinder 22 is activated, and the lifting plate 21 is lifted vertically through the telescopic shaft of the lifting cylinder 22. During the lifting process, the lifting plate 21 drives the rotating mechanism 3, so that the workpiece positioning plate 33 at the top docks with the workpiece and lifts the workpiece away from the production line. Then, the rotary motor 31 starts to run, and the workpiece positioning plate 33 and the workpiece are rotated through the rotating shaft 32. The rotation of the workpiece allows the cleaning equipment (such as anti-static fans, dry ice dust removal equipment, etc.) to reach all areas of the workpiece without dead angles, ensuring that there are no missed cleaning areas on the surface of the workpiece, thereby improving the cleaning effect and cleaning efficiency.

[0027] Immediately after the cleaning work is completed, the lifting cylinder 22 drives the lifting plate 21 to move down, so that the workpiece positioning plate 33 moves the workpiece down into the production line. Then the production line starts and transports the workpiece to the next station.

[0028] In the production line to which this utility model is adapted, a corresponding cleaning station is set up on the production line, and a position sensor is set up in the cleaning station. When the workpiece arrives at the cleaning station, the position sensor is triggered and transmits a signal to the control terminal, so that the control terminal sends a stop command and sends a start command to the assembled electrostatic fan, dry ice dust removal equipment and other cleaning equipment.

[0029] Among them, the rotary motor 31 is preferably a servo motor, and a harmonic reducer is used as the reduction mechanism to ensure that the rotational positioning accuracy meets the production requirements.

[0030] like Figure 1-2 As shown, based on the above embodiment, it is further proposed that sliding guide rails 4 are provided on both sides inside the frame 1, and guide sleeves 23 that slide in cooperation with the sliding guide rails 4 are provided on both sides of the lifting plate 21.

[0031] Specifically, the lifting plate 21 slides with the sliding guide rail 4 set on the frame 1 through the guide sleeves 23 on both sides, so that the movement trajectory of the lifting plate 21 is guided vertically with high precision, ensuring that the workpiece positioning plate 33 can accurately dock with the workpiece.

[0032] like Figure 1-3 As shown, based on the above embodiment, it is further proposed that a mounting frame 5 located at the lower end of the lifting plate 21 is provided between the sliding guide rails 4 on both sides, and the lifting cylinder 22 is installed on the mounting frame 5; the mounting frame 5 is provided to fix the lifting cylinder 22 at the lower end of the lifting plate 21, and the telescopic end of the lifting cylinder 22 passes through the mounting frame 5 and is fixedly connected to the lifting plate 21, so as to realize the vertical driving of the lifting plate 21.

[0033] like Figure 1-2 As shown, based on the above embodiments, it is further proposed that there are two rotary motors 31 and two workpiece positioning plates 33, which are distributed on both sides of the edge of the lifting plate 21. By setting two rotary motors 31 and two workpiece positioning plates 33, two workpieces can be lifted and rotated simultaneously, which further improves the workpiece cleaning efficiency.

[0034] The rotary motor 31 is installed at the lower end of the lifting plate 21, and the rotating shaft 32 passes through and extends to the upper end of the lifting plate 21 and is fixedly connected to the workpiece positioning plate 33.

[0035] Specifically, the rotary motor 31 is installed at the lower end of the lifting plate 21. The lifting plate 21 can be used to protect the rotary motor, so as to reduce the damage to the equipment caused by dust and other debris coming into contact with the rotary motor 31. The rotary shaft 32 connected to the output end of the rotary motor 31 passes through the preset through hole on the lifting plate 21 and is connected to the workpiece positioning plate 33.

[0036] like Figure 4As shown, based on the above embodiments, it is further proposed that the upper end of the workpiece positioning plate 33 is provided with a plurality of positioning posts 34, and the positioning posts 34 are tapered.

[0037] Specifically, during the production process, multiple workpiece fixture plates (not shown in the figure) are transported on the conveyor line. These fixture plates can simultaneously hold multiple workpieces and are equipped with positioning holes corresponding to the positioning posts 34. When the workpiece positioning plate 33 is pushed up, the positioning posts 34 can interlock with the positioning holes. Four positioning posts 34 can be set in a square distribution to fix the fixture plate used to hold the workpieces in place using geometric relationships, preventing them from coming off during rotation. The positioning posts 34 with a conical structure can gradually interlock with the positioning holes during the interlocking process, thereby reducing hard collisions and minimizing damage.

[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.
