Description

Technical Field

[0001] The present invention relates to the technical field of laser green cleaning, and in particular to an automated commutator laser cleaning device and method. Background Art

[0002] There are various cleaning methods in the traditional cleaning industry, most of which are chemical agents and mechanical methods. As my country's environmental protection laws and regulations are becoming more and more stringent and people's environmental protection and safety awareness are increasing, the types of chemicals that can be used in industrial production cleaning will become fewer and fewer. How to find a cleaner and non-destructive cleaning method is a problem we have to consider. Laser cleaning has the characteristics of no grinding, no contact, no heat effect, and is suitable for objects of various materials. It is considered to be the most reliable and effective solution. At the same time, laser green cleaning can solve problems that cannot be solved by traditional cleaning methods.

[0003] The commutator is one of the important parts of a car. Its function is to make the current direction in the armature winding alternate to ensure that the direction of the electromagnetic torque remains unchanged. After forming, the commutator needs to be cleaned of surface oil and related mechanical impurities such as burrs to make the commutator product have good insulation performance. However, the existing commutator mainly uses chemical cleaning to remove residual polymers on the surface, which causes great pollution to the environment. Therefore, it does not meet the existing needs. In this regard, we propose an automated commutator laser cleaning equipment and method. Summary of the invention

[0007] Preferably, the automatic feeding mechanism includes a fixed arm, a movable arm, a feeding head, a first cylinder, a second cylinder, a fixed plate, a guide rod, a connecting plate and a material trough, a material trough is provided at one end of the fixed arm, a fixed plate is provided at the front end of the fixed arm, a guide rod is provided between the fixed arm and the fixed plate, and one end of the guide rod passes through and extends to the outside of the fixed plate, a movable arm is installed on the guide rod, and the movable arm is slidably connected to the guide rod, a feeding head is installed at one end of the movable arm, a first cylinder is installed above the movable arm, and the output end of the first cylinder is fixedly connected to the fixed plate, the fixed arm and the fixed plate are fixedly connected via a connecting plate, and a second cylinder is installed on one side of the connecting plate.

[0008] Preferably, the positioning and unloading mechanism includes a linear bearing, a servo motor, a positioning rod and a tooling disk. A servo motor is provided on one side of the linear bearing, and a positioning rod is installed on the output end of the servo motor. One end of the positioning rod passes through and extends to the outside of the linear bearing and is transmission-connected to the tooling disk. A work station is provided inside the tooling disk, and there are three work stations.

[0009] Preferably, a feed port is provided on the upper surface of the cleaning table, and a ramp mechanism is provided inside the cleaning table.

[0010] Preferably, a shock-absorbing pad is provided on the outer wall of the ramp mechanism, and a discharge door is installed on the front end surface of the cleaning table.

[0011] Preferably, a water cooling device is provided on one side of the laser cleaning machine, a laser is installed on the output end of the laser cleaning machine, and the laser is fixedly connected to the cleaning table through a laser bracket, a touch panel is provided on the front end surface of the laser cleaning machine, an emergency stop switch, a key switch and a start button are provided on one side of the touch panel, and a self-contained bracket is provided on the top of the laser cleaning machine.

[0012] Preferably, the laser is a laser of model MRJ-FL-CD.

[0013] Preferably, the cleaning method of a commutator laser cleaning automation equipment comprises the following steps:

[0014] Step 1: Pour several commutators to be cleaned into the feeding tray. The electromagnet inside the feeding tray can generate suction to make the tray vibrate up and down, thereby introducing the commutators into the discharge guide rail one by one;

[0015] Step 2: Enter the inside of the discharge guide rail, and the commutator arranged at the bottom will fall into the trough of the fixed arm of the automatic feeding mechanism. At this time, the automatic feeding mechanism is started, and the second cylinder drives the mechanism to move right as a whole until the center point of the trough is located at the top station of the tooling plate. The first cylinder is started to make the movable arm slide along the guide rod, and the feeding head at one end of it is used to push the commutator into the station to complete the feeding and positioning of the commutator. After the feeding is completed, the automatic feeding mechanism returns to its position to wait for the next feeding;

[0016] Step 3: Start the laser cleaning machine, and use the laser directly above the workstation to irradiate the commutator inside to remove the polymer on the surface of the commutator;

[0017] Step 4: After cleaning, start the servo motor to drive the tooling disc to rotate and switch to the next station, repeat the loading steps in step 2, and continue the automated processing. While switching, the parts of the previous station will automatically fall into the feed port of the cleaning table below to complete the unloading of the commutator. A ramp mechanism is set in the cleaning table, and a shock-absorbing pad is installed on the outer wall of the ramp mechanism, which can play a role in shock absorption and buffering, making the commutator unloading more stable.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention removes the polymer on the surface of the commutator by setting up a laser cleaning machine. When in operation, the laser cleaning machine uses its own resonant cavity to focus light on the laser, so that it emits a light beam and radiates the commutator to be cleaned. After the polymer on the surface of the commutator absorbs the high-energy light beam, a rapidly expanding plasma will be formed inside it, generating a shock wave, thereby turning itself into fragments and being removed. Compared with traditional chemical cleaning, it is green and environmentally friendly and will not damage the surface of the commutator.

[0020] 2. By setting up the feed tray main body, automatic loading mechanism, positioning unloading mechanism and laser cleaning machine, and using them together, a complete set of commutator automatic cleaning processing flow can be formed. In addition, laser cleaning is used to remove the polymer on the commutator surface, which is more environmentally friendly than chemical cleaning.

[0021] 3. The commutator is fixed by using an automatic feeding mechanism in combination with a positioning rod. If commutators of different specifications need to be cleaned, it is only necessary to replace the fixing arm with the same trough size as the commutator and the positioning rod of the corresponding size. It is widely applicable. BRIEF DESCRIPTION OF THE DRAWINGS
