Description

Technical Field

[0001] This utility model relates to the field of paint spraying technology for drive motors, and in particular to a multi-axis linkage paint spraying device. Background Technology

[0002] In the production of the stator, the core structure of the drive motor, varnish coating is an essential step. The insulating varnish solidifies the stator windings into a whole, providing an unobstructed heat dissipation channel, improving the stator's shock resistance, insulation, moisture resistance, and corrosion resistance, thereby enhancing the motor's mechanical strength and electrical performance, delaying motor aging, and also helping to improve the NVH characteristics of the entire vehicle.

[0003] Currently, the stator varnishing machine is a piece of equipment used in motor production. Its main function is to uniformly coat the motor stator windings with insulating varnish through an automatic dripping process. Its core functions are: to fill the winding gaps by impregnating with varnish to form an insulating layer and prevent short circuits; the cured varnish film can prevent moisture and corrosion and improve the heat dissipation of the windings; and to fix the winding wires, reduce vibration and wear, and extend the motor's life.

[0004] The existing technical solutions have the following drawbacks: existing paint dripping machines usually have a limited paint dripping range, making it difficult to cover complex winding structures, and their adjustment flexibility is insufficient, affecting coating uniformity and production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a multi-axis linkage paint dripping device to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A multi-axis linkage paint dripping device, comprising:

[0008] The worktable has a rotating shaft mounted on its right side, and a gripping robot arm fixedly mounted on the left end of the rotating shaft. The gripping robot arm is used to grip the workpiece to be dripped with paint, and a servo motor is fixedly mounted on the top of the worktable.

[0009] A linear drive motor is fixedly mounted on the top of the worktable. The linear drive motor includes a fixed end and a movable end, and the linear drive motor performs reciprocating motion in the back-and-forth direction.

[0010] A moving mechanism is disposed on top of the movable part of the linear drive motor, and the left side of the moving mechanism is connected to the servo motor via a transmission.

[0011] A paint-drip mechanism is fixedly installed at the bottom of the moving mechanism and is used to drip paint onto the workpiece.

[0012] By adopting the above technical solution, paint can be applied to the stator windings of the drive motor. The moving part of the linear drive motor moves linearly back and forth at the top of the worktable, thereby driving the paint application mechanism to move back and forth. When different stator windings need to be coated with paint, the front and back positions of the paint application mechanism can be adjusted by the linear drive motor to adapt to stator windings of different sizes. The servo motor can drive some parts in the moving mechanism to move left and right, thereby making the paint application mechanism move back and forth in the left and right directions to expand the paint application area of ​​the stator windings.

[0013] In a further embodiment, the moving mechanism includes:

[0014] A fixing plate is fixedly installed on the top of the linear drive motor, and bearing seats are provided at intervals on the left side of the fixing plate;

[0015] A screw, which passes through and extends to the outside of the bearing housing, and the left end of the screw is connected to the output shaft of the servo motor.

[0016] The first slider has a threaded hole that runs through the left and right sides at its left end. The first slider is screwed onto the screw rod, and a first paint dripping pipe is fixedly installed at the bottom end of the first slider.

[0017] The second slider has the same structure as the first slider. The second slider is spaced apart on one side of the first slider. The second slider is screwed onto the screw rod. The bottom end of the second slider is fixedly installed with a second paint dripping pipe.

[0018] The limiting rod unit includes a first round rod and a second round rod. The first round rod and the second round rod are symmetrically arranged about the front and rear ends of the first slider and the second slider about the axis of the screw. The axes of the first round rod and the second round rod are parallel to the axis of the screw. The left ends of the first round rod and the second round rod are fixedly connected to the fixing plate. The right end of the first round rod passes through the first slider and the second slider from left to right. The first round rod is slidably connected to the first slider and the second slider respectively. The right end of the second round rod passes through the first slider and the second slider from left to right. The first round rod is slidably connected to the first slider and the second slider respectively.

[0019] By adopting the above technical solution, the servo motor can drive the screw to rotate forward and reverse. Because both ends of the first and second sliders are restricted by the first and second round rods, and both the first and second sliders have threaded holes inside, the first and second sliders cannot rotate with the rotation of the screw. The first and second sliders can only move left and right along the screw. The movement distance of the first and second sliders can be controlled by controlling the forward and reverse rotation time of the servo motor.

[0020] In a further embodiment, the first dripping conduit includes a first straight pipe, a second straight pipe, and a first nozzle. The first straight pipe and the second straight pipe are connected. The first straight pipe is disposed at the top of the second straight pipe. The bottom end of the second straight pipe is inclined towards the side closer to the workpiece. The bottom end of the second straight pipe is connected to the first nozzle. The top end of the first straight pipe is connected to one end of a first flexible tube.

[0021] By adopting the above technical solution, the second straight tube can be inserted into the interior of the stator winding to apply paint to the interior of the stator winding.

[0022] In a further embodiment, the second dripping conduit includes a third straight pipe and a second nozzle, the second nozzle being disposed at the bottom end of the third straight pipe, the third straight pipe and the second nozzle being connected, and the top end of the third straight pipe being connected to one end of a second flexible tube.

[0023] By adopting the above technical solution, the third straight tube can directly apply paint to the outside of the stator winding.

[0024] In a further embodiment, the other ends of the first hose and the second hose are connected to the same insulating varnish pump.

[0025] By adopting the above technical solution, the insulating varnish pump injects high-voltage insulating varnish into the first hose and the second hose.

[0026] In a further embodiment, the gripping manipulator includes a drive cylinder, a first crossbar, and a second crossbar. The axes of the first and second crossbars are parallel to each other. The drive cylinder includes a fixed end and a movable end. The side wall of the fixed part of the drive cylinder is fixedly connected to the right end of the rotating shaft. The left end of the first crossbar is fixedly installed on the top of the movable end of the drive cylinder. The right end of the second crossbar is fixedly installed on the bottom of the fixed end of the drive cylinder. Limiting protrusions are respectively provided on the opposite sides of the right ends of the first and second crossbars.

[0027] By adopting the above technical solution, the moving end of the drive cylinder can move linearly up and down, thereby driving the first crossbar to move linearly up and down. When it is necessary to fit the stator winding onto the first and second crossbars, it is only necessary to shorten the distance between the first and second crossbars so that the distance between the top of the limiting protrusion on the first crossbar and the bottom of the limiting protrusion on the second crossbar is less than the inner diameter of the stator winding. The stator winding is successfully fitted onto the first and second crossbars. Then, the distance between the first and second crossbars is widened so that the first and second crossbars fit tightly against the inner wall of the stator winding. The limiting protrusions can prevent the stator winding from slipping off the first and second crossbars, thus achieving the purpose of firmly fixing the stator winding onto the first and second crossbars. Finally, the stator winding rotates together with the shaft.

[0028] In a further embodiment, a recycling tray is provided at intervals on one side of the workbench.

[0029] By adopting the above technical solution, the insulating varnish that does not drip onto the stator winding will drip into the recycling tray.

[0030] In summary, this utility model has the following beneficial effects:

[0031] 1. The movable part of the linear drive motor can move linearly in the front and back direction at the top of the worktable, thereby driving the paint dripping mechanism to move in the front and back direction. When it is necessary to drip paint on different stator windings, the front and back positions of the paint dripping mechanism can be adjusted by the linear drive motor, which can adapt to the stator windings of different sizes for paint dripping.

[0032] 2. A servo motor can drive some parts of the moving mechanism to move in the left and right directions, thereby enabling the paint dripping mechanism to move back and forth in the left and right directions, which can expand the paint dripping area on the stator winding.
