Description

Technical Field

[0001] The present invention belongs to the technical field of surface cleaning of copper products, and specifically relates to a method and equipment for surface cleaning of copper products used in automobile drive motors. Background Art

[0002] With the continuous innovation of automobile industry technology, especially in the research and development of electrostatic release brush boxes for the drive motors of Volkswagen electric vehicles, the one-piece copper stamping parts inside the electrostatic release brush boxes require not only the dimensional accuracy of the product processing, but also the cleanliness performance requirements of the product surface after processing.

[0003] At present, ultrasonic cleaning is commonly used in the stamping industry to clean products. Ultrasonic cleaning includes rough cleaning, fine cleaning, rinsing and drying. Rough cleaning, fine cleaning and rinsing processes require a large amount of water to complete. The wastewater after cleaning needs to be treated by professional treatment equipment before it can be discharged, which is neither economical nor environmentally friendly. At the same time, although ultrasonic cleaning has a post-drying process, the post-drying process will cause moisture to remain for products with more bends and products assembled from multiple sub-parts. Residual moisture can easily cause products to rust, especially copper products. Summary of the invention

[0004] In order to solve the above problems, this paper proposes a surface cleaning device for copper products for automobile drive motors, wherein a material frame is arranged inside the cleaning device, and the material frame is arranged above the inside of a waste collection box, the waste collection box comprises a collection and sweeping chamber and a vibrating material dropping chamber, and a lifting and vibrating cleaning device is arranged inside the waste collection box, and an air-controlled cleaning device is arranged above the outer side of the waste collection box, the air-controlled cleaning device comprises a high-pressure air knife and a rodless cylinder, and a material frame is fixedly installed above the lifting and vibrating cleaning device, the lifting and vibrating cleaning device comprises a lifting pole, a vertical moving motor, a two-way vibration component, a shock-absorbing protection component and a vibration bracket, the lifting pole is symmetrically arranged on the left and right sides of the inside of the waste collection box, the outside of the lifting pole is vertically connected with a vertical moving motor, and the top inner surface of the lifting pole is provided with a shock-absorbing protection component. The protective component, the surface of the shock-absorbing and protective component is provided with a two-way vibration component, the inner side of the shock-absorbing and protective component is vertically upwardly provided with a vibration bracket, the bottom outer side of the lifting pole is provided with a protection locking pin, the protection locking pin is through-type arranged on the outer side of the waste collection box, the upper part of the vibration bracket is provided with a material frame in a clamping manner, the upper part of the material frame is provided with a high-pressure air knife in a longitudinal manner, the rear end of the high-pressure air knife is connected to the rodless cylinder for left and right translation through the vertical bracket, and the air energy cleaning method is used instead of ultrasonic cleaning, which can prevent the risk of rust and oxidation of the product in the later stage, and also uses high-frequency vibration for pretreatment to ensure the cleaning effect of air cleaning, and the protection locking pin arranged on the outer side of the lifting pole is used to prevent damage to the lifting component during the vibration process. The self-developed cleaning equipment can be used for surface cleaning of various products and products of different types of materials.

[0005] The waste collection box is a double-chamber box, with a collection and sweeping chamber at the front end of the waste collection box and a vibrating blanking chamber at the rear end of the waste collection box. A lifting and vibrating cleaning device is provided inside the vibrating blanking chamber, and an air-controlled cleaning device is provided outside the vibrating blanking chamber. The bottom of the front surface of the vibrating blanking chamber is connected to the collection and sweeping chamber, and a slope cutting edge is provided on the top of the vibrating blanking chamber. Through the two waste collection boxes with two chambers, it is convenient to collect the cleaned impurities and debris, and to clean and discharge the material from the outside, so as to realize the overall debris cleaning and packaging.

[0006] The vertical moving motor is symmetrically arranged on the left and right sides of the inner bottom surface of the vibrating blanking cavity. Two lifting uprights are vertically penetrated in the middle of each vertical moving motor. The bottom of the lifting upright of the vertical moving motor is vertically connected to the bottom surface of the vibrating blanking cavity and is provided with a upright bottom sleeve. The interior of the upright low sleeve is embedded with a lifting upright. The vertical upright is lifted and lowered by the vertical moving motor, so that the transfer frame can receive the copper product. The upright bottom sleeve at the bottom can allow the vertical upright to move downward in a limited manner, thereby ensuring the stable displacement of the lifting upright.

[0007] The shock-absorbing and protective component includes a transverse vibration damping slider, a vertical vibration damping slider and a vibration connecting rod. The vibration connecting rod is longitudinally and horizontally arranged at the top of the lifting vertical rod on one side of the inside of the vibration blanking cavity. The two ends of the outer surface of the vibration connecting rod are connected to the lifting vertical rod through the vertical vibration damping slider, and the two ends of the inner surface of the vibration connecting rod are connected to the vibration bracket through the transverse vibration component slider. The vertical vibration damping slider is embedded in the inner top of the lifting vertical rod, and the transverse vibration damping slider is embedded in the inner two ends of the vibration connecting rod. The middle parts of the inner and outer sides of the vibration connecting rod are respectively provided with a transverse vibrator and a vertical vibrator. The shock-absorbing and protective component can realize the vibration effect with amplitude in two axes, so that the vibration bracket can perform high-frequency vibration with a small amplitude during the vibration of the vibrator, which can not only protect the lifting rod from being driven to damage the lifting assembly, but also increase the vibration frequency and the vibration pretreatment effect.

[0008] The material frame is a rectangular frame of a welded assembly of brackets. The bottom of the material frame is snap-fitted to the inner side of the vibration bracket. The bottom surface of the material frame is criss-crossed with grid bottom plates. The surface focal points of the grid bottom plates are all provided with feeding tubes. The outer sides of the feeding tubes are plug-inly provided with copper products. Through the material frame, the copper components can be directly and conveniently assembled and installed using the feeding tubes. The design of the grid bottom plates with staggered brackets can also facilitate the downward dropping of debris during vibration and blowing, thereby achieving an efficient cleaning effect.

[0009] The high-pressure air knife is a strip-shaped air outlet knife with a downward direction. The top surface of the high-pressure air knife is connected to the high-pressure pump through an air pipe. The rear end of the high-pressure air knife is vertically connected with an upright bracket. The bottom of the upright bracket is connected to the rodless cylinder sleeve through a pneumatic slider. The rodless cylinder is horizontally arranged at the rear bottom of the waste material collection box. The rodless cylinder is connected to the high-pressure pump through an air pipe. The high-pressure air knife achieves a stable and efficient cleaning effect of air energy, ensuring the cleaning effect without chemically affecting the product materials and physically damaging the outer surface.

[0010] The copper products to be cleaned are manually taken out from the turnover box and placed one by one on the feeding guide rail. The discharge port of the feeding guide rail is aligned with the material frame on the material frame conveyor outside the cleaning equipment. The discharge port of the feeding guide rail and the material pipe of the material frame are on the same horizontal line. After the material frame is full of material, it is moved to the rear end by the longitudinal moving guide rail of the material frame, so that the rear end of the material frame is connected to the transverse moving guide rail of the material frame on the rear side. The material frame is first moved from left to right through the transverse moving guide rail of the material frame on the rear side, and then assisted in alignment and movement by the transverse moving guide rail of the material frame on the front side. When the material frame is above the vibration bracket, the vibration bracket is automatically raised by the lifting rod, the material frame is lifted up by the vibration bracket, and the material frame is fixedly connected to the vibration bracket by clamping. The horizontal vibrator and vertical vibrator installed on the surface of the moving connecting rod are started, and the material frame vibrates with the platform. At this time, the larger solid particles attached to the surface of the copper product in the material frame, such as stamping material waste, burrs or other debris, will automatically fall off, completing the vibration pretreatment process; after the vibration pretreatment is completed, the high-pressure air knife suspended above the material frame is translated left and right by the rodless cylinder outside the vibration blanking cavity, and the air outlet of the high-pressure air knife releases high-pressure airflow evenly, and the high-pressure airflow contacts the copper product. The fine solid particles, fibers, and debris on the copper product fall to the bottom of the vibration blanking cavity with the high-pressure airflow, and then are swept and cleaned from the collection and cleaning cavity; after the copper product is cleaned, the material frame is manually removed, and a new material frame is replaced and placed in the material frame fixing frame, and then a new round of cleaning mode can be entered.

[0011] Beneficial effects:

[0012] Using air cleaning method instead of ultrasonic cleaning can reduce the risk of rust and oxidation of the product in the later stage, and also pre-treating through high-frequency vibration to ensure the cleaning effect of air cleaning. The protective locking pin set on the outside of the lifting pole can prevent damage to the lifting component during the vibration process. The self-developed cleaning equipment can be used for surface cleaning of various products and products of different types of materials.

[0013] Two waste collection boxes with two chambers make it easy to collect the cleaned impurities and debris, and to clean and discharge the material from the outside, so as to realize overall debris cleaning and packaging.

[0014] The vertical moving motor is used to make the vertical pole move up and down, so that the transfer frame can receive the copper products. The bottom sleeve of the pole can make the vertical pole move downward in a limited manner to ensure the stable displacement of the lifting pole.

[0015] The shock-absorbing protection component is used to achieve a vibration effect with amplitude in two axes, so that when the vibrator is vibrating, the vibration bracket can vibrate with a small amplitude and high frequency. This not only protects the lifting rod from being damaged by the lifting component, but also increases the vibration frequency and the effect of vibration pretreatment.

[0016] The high-pressure air knife achieves a stable and efficient cleaning effect of air energy, ensuring the cleaning effect without chemically affecting the product material or physically damaging the outer surface. BRIEF DESCRIPTION OF THE DRAWINGS
