Description

Technical Field

[0001] This utility model relates to the field of harmonic reducer manufacturing technology, specifically a harmonic reducer coating device. Background Technology

[0002] Harmonic reducer coating devices are mainly used for applying adhesives or spraying coatings to key components of harmonic reducers to improve their sealing, wear resistance, or lubrication performance. A typical harmonic reducer coating device consists of an adhesive application mechanism, a push rod mechanism, and a feeding mechanism. The harmonic reducer component to be coated is placed on the feeding mechanism, where it is precisely positioned via an indexing plate and transmission system. The push rod mechanism then activates, lifting the component upwards to clamp it against the pressure cap shaft system of the adhesive application mechanism. Harmonic reducer coating devices are widely used in high-end fields such as robotics and semiconductor manufacturing.

[0003] For example, Chinese patent CN220991407U, entitled "A Surface Spraying Device for Harmonic Reducer Processing," includes a spraying device, a storage tank, a supply device, and a clamping mechanism. The spraying device includes a worktable, a chassis, a slide, a rotating shaft, a fixed block, a turntable, and a first motor. The worktable is located inside the spraying device. The chassis is rotatably connected to the worktable via a connecting shaft. The slide is located on both sides of the upper end of the chassis. The upper side of the turntable is fixedly connected to the rotating shaft of the motor. The inner side of the turntable is fixedly connected to the upper side of the fixed block. The upper side of the rotating shaft is fixedly connected to the lower end of the fixed block. The motor is fixedly mounted on the upper surface of the spraying device. The storage tank is located at the lower end of the spraying device, and the supply device is located at the left end of the storage tank.

[0004] While the existing technologies can achieve the coating of harmonic reducers, in practical use, on the one hand, paint splashing is prone to occur during spraying. Usually, during the spraying operation, the paint is sprayed out from the spray seat, causing some paint to splash off the processing table, thus posing a threat to the safety of operators. On the other hand, the spraying effect of harmonic reducers is not good enough. Usually, the spraying mechanism is fixed, causing the spraying mechanism to spray the harmonic reducer at the same position, thereby reducing the uniformity of spraying. Therefore, it does not meet the current requirements. In response, we propose a coating device for harmonic reducers. Utility Model Content

[0005] The purpose of this invention is to provide a coating device for a harmonic reducer, so as to solve the problems mentioned in the background art, such as easy liquid splashing during spraying and insufficient spraying effect of the harmonic reducer.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a harmonic reducer coating device, comprising a processing table, with support rods fixedly installed at the four corners of the lower end of the processing table, and fixed plates fixedly installed on both sides of the upper end of the processing table, with slide rails fixedly installed at the front and rear ends of the upper end of the processing table, the slide rails contacting the fixed plates on both sides, a first movable frame is provided above the processing table on one side of the fixed plate, the lower end of the first movable frame slidingly engages with the slide rail, a telescopic cover is fixedly installed between the first movable frame and the fixed plate, and two plug-in seats are provided above the side of the first movable frame near the processing table, the plug-in seats being equidistantly distributed.

[0007] Preferably, a second movable frame is provided at the center of the upper end of the processing table. The interior of both the front and rear ends of the second movable frame is provided with slots, which correspond to the positions of the plug-in bases. The interior of both the plug-in bases and the slots is provided with through holes. The through holes are through-holes, and the positions of the through holes on the plug-in bases and the through holes on the slots correspond. A pin is provided inside the through hole, and the lower part of the pin extends through the through hole to the lower part of the second movable frame.

[0008] Preferably, the processing table is provided with a drive cavity inside the slide rail outside. The drive cavity has an open structure, and the lower end of the second moving frame extends into the drive cavity and slides into the drive cavity. A lead screw is provided inside the drive cavity, and both sides of the lead screw are rotatably connected to the drive cavity. The lead screw passes through the second moving frame.

[0009] Preferably, a servo motor is fixedly installed inside the processing table on one side of the drive cavity, and the output shaft of the servo motor extends into the drive cavity and is fixedly connected to the lead screw.

[0010] Preferably, a snap-fit ​​cavity is provided at the center of the processing table. The snap-fit ​​cavity has a through structure, and a workpiece plate is provided inside the snap-fit ​​cavity. The workpiece plate has a mesh structure inside.

[0011] Preferably, a base is fixedly provided between the support rods, and a collection box is provided at the upper end of the base, with the collection box corresponding to the opening position of the snap-fit ​​cavity.

[0012] Preferably, an inlet pipe is fixedly installed at the upper end of the second movable frame. The inlet pipe is a telescopic structure. A spray seat is installed below the second movable frame. The spray seat is connected to the inlet pipe through a pipe, and the spray seat corresponds to the position of the workpiece plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can shield the spraying mechanism through the first movable frame and the telescopic cover. Before spraying the workpiece, the workpiece is placed on the workpiece plate. At this time, the operator pulls the first movable frame on both sides, so that the first movable frame moves towards the second movable frame on the slide rail. At the same time, the telescopic cover is gradually unfolded until the plug is pushed into the slot. Then, the pin is aligned with the through hole opening on the second movable frame and inserted into the through hole until the lower end of the pin passes through the plug and extends to the bottom of the second movable frame, thus completing the fixation of the first movable frame. At the same time, the position of the spraying mechanism is shielded by the telescopic cover, thereby improving the safety of the spraying operation.

[0015] (2) The position of the spraying mechanism can be adjusted by the second moving frame and the lead screw. When the workpiece is sprayed, the paint is sprayed out from the spraying seat. At this time, the servo motor is turned on, so that the output shaft of the servo motor drives the lead screw to rotate. The second moving frame is moved in the drive cavity through the thread on the outside of the lead screw until the second moving frame is moved to one side of the drive cavity. At this time, the energizing direction of the servo motor is changed, so that the lead screw drives the second moving frame to reciprocate inside the drive cavity, thereby realizing the spraying mechanism to spray the workpiece reciprocally, thereby improving the uniformity of the workpiece spraying.

[0016] (3) This utility model collects and treats the waste liquid generated by the workpiece plate and the collection box. When the workpiece is sprayed, the spraying seat continuously sprays the workpiece. At this time, the paint accumulated on the surface of the workpiece flows from the workpiece to the workpiece plate. At the same time, the paint drips into the collection box through the mesh inside the workpiece plate until the workpiece spraying operation is completed. At this time, the operator collects and treats the waste in the collection box and recycles it, thereby reducing the cost of workpiece spraying. Attached Figure Description
