[0044] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0045] It should be noted that when an element is referred to as being "fixed on" or "set on" another component, it can be directly on the other component or indirectly set on the other component; when a component is referred to as being "connected to" another component, it can be directly connected to the other component or indirectly connected to the other component.

[0046] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0047] Please refer to Figures 1 to 8 The present invention provides a non-contact metal ball rapid coating preparation device, characterized in that it includes: a base plate 1, a magnetic suspension mechanism 2 installed on the base plate 1 and a plurality of coating mechanisms 3 installed corresponding to the magnetic suspension mechanism 2; a loading mechanism 4 is arranged at one end of the coating mechanism 3, and a unloading mechanism 5 is arranged at the other end.

[0048] The magnetic suspension mechanism 2 comprises a screw-nut pair mounted on the base plate 1 and a magnetic suspension assembly 24 mounted on the nut of the screw-nut pair 23 .

[0049] The coating mechanism 3 includes a coating pipe 31 arranged parallel to the screw of the screw nut pair 23, and a liquid coating input component 33 connected and installed on the coating pipe 31; the metal ball is suspended in the coating pipe 31 through the magnetic suspension component 24, and the liquid coating input component 33 sprays liquid coating onto the metal ball in the coating pipe 31.

[0050] In this embodiment, the magnetic suspension mechanism 2 enables the metal ball to be suspended and enter the coating pipe 31 for spraying the coating, and the suspended liquid droplets are coated on the surface of the metal ball when passing through the liquid input component 33, and then the metal ball continues to move forward through the magnetic suspension mechanism 2 to enter the feeding mechanism 5 to complete the preparation of the metal ball. This structure enables the metal ball to move in suspension, realizes non-contact operation, and makes the spraying of the coating more uniform, efficient and convenient, and ensures the quality of preparation.

[0051] In this embodiment, a number of metal balls are placed in the feeding mechanism 4, and the metal balls are slid and rolled into the coating pipe 31 in turn through the feeding mechanism 4, and the metal balls are suspended in the coating pipe 31 through the magnetic suspension mechanism 2, and as the magnetic suspension component 24 moves on the screw of the screw nut pair 23, the metal balls are driven to move in the coating pipe 31, and the suspended liquid droplets are coated on the surface of the metal balls when passing through the liquid coating input component 33, and then the metal balls after the coating is sprayed are sent out of the coating pipe 31 through the movement of the magnetic suspension component 24, and sent to the unloading mechanism 5 for storage.

[0052] It is further explained that the magnetic levitation mechanism 2 also includes a first motor 22 for driving the screw nut pair to perform reciprocating motion. Driving the first motor 22 causes the screw nut pair 23 to perform reciprocating motion, driving the magnetic levitation component 24 fixedly mounted on the nut of the screw nut pair to perform reciprocating motion on the screw, causing the metal ball to levitate accordingly. The setting of the magnetic levitation component 24 realizes contactless coating spraying, making the coating spraying more uniform and convenient.

[0053] It is further explained that the coating mechanism 3 can be provided in multiple numbers, and the coating mechanism 3 at the front end is docked and installed with the feeding mechanism 4 .

[0054] It is further explained that the magnetic suspension assembly 24 includes: a mounting groove 241 fixedly mounted with the lead screw nut pair, a plurality of groups of electromagnets 242 mounted in the mounting groove 241 , and a partition plate 243 spaced between each group of electromagnets 242 .

[0055] When the power is turned on, the strength of the magnetic field generated by the electromagnet 242 can be changed by changing the strength of the current flowing through the electromagnet 242, thereby adaptively adjusting the suspension force of the metal ball, and then adjusting the suspension height of the metal ball, to ensure that the metal ball passes through the coating pipe 31 and remains suspended under the action of sufficient suspension force; the metal ball can also be driven to rotate by controlling the current strength and direction of the electromagnet 242, and enter the coating pipe 31 in a rotating state, thereby improving the coating preparation effect of the metal ball, and the rotation speed of the metal ball can be adjusted by changing the current frequency, so that the coating spraying is more uniform.

[0056] It is further explained that the provision of the partition 243 avoids the magnetic influence between adjacent electromagnets 242 and ensures the working quality of each group of electromagnets 242.

[0057] like Figure 5 As shown, acoustic wave suspension components 34 for suspending and dripping the liquid coating are arranged on both sides of the coating pipe 31 corresponding to the liquid coating input component 33 .

[0058] In this embodiment, the acoustic wave suspension component 34 includes an acoustic wave mounting frame 35 fixedly mounted on the bottom plate 1, an acoustic wave transmitting end 341 and an acoustic wave receiving end 342 arranged on both sides of the coating pipe 31, and the acoustic wave transmitting end 341 and the acoustic wave receiving end 342 are fixedly mounted on the acoustic wave mounting frame 35 through a fixing rod 343. The acoustic wave transmitting end 341 emits acoustic waves, and the acoustic wave transmitting end 342 receives acoustic waves to make the liquid coating dripped into the coating pipe 31 in a suspended state, and smoothly and evenly coated on the surface of the metal ball when the metal ball passes by.

[0059] It is further explained that the sonic suspension component 34 is powered on, so that the sonic wave transmitting end 341 emits sonic waves, the sonic wave receiving end 342 receives sonic waves, and the liquid dripping from the liquid coating input component 33 can be suspended in the coating pipe 31. When the metal ball passes by, the suspended droplets can be stably coated on the surface of the metal ball. The setting of the sonic suspension component 34 can achieve a uniform and stable combination of the liquid coating and the metal ball, so that the spraying effect is better and the coating quality of the metal ball is guaranteed.

[0060] like Figure 5 As shown, a waste pipe 36 for discharging waste is installed at the lower side of the coating pipe 31 corresponding to the liquid coating material input assembly 33 .

[0061] In this embodiment, some residual liquid will be generated after the liquid coating combines with the metal balls. In order to facilitate the residual liquid to flow smoothly into the waste pipe 36 arranged on the lower side of the coating pipe 31, a water pump 39 is installed on the waste pipe 36; the waste liquid is pumped into the waste pipe 36 by the water pump 39, and flows along the waste pipe 36 to the waste liquid box 38, which is convenient for the reuse of the waste liquid, saving resources and reducing costs.

[0062] like Figure 1-Figure 2 As shown, the tail end of the coating mechanism 3 is provided with an induction heating component 6 for rapidly drying the metal ball coating.

[0063] In this embodiment, after the metal ball exits the coating pipe 31, the coating on the surface of the metal ball has not dried yet. If the metal ball is fed into the unloading mechanism 5 at this time, the coating will stick to the inner wall of the discharge channel 55, and it may also cause two adjacent metal balls to stick together in the storage tank 57, affecting the coating quality of the metal ball. Therefore, an induction heating component 6 is provided at the tail end of the coating mechanism 3 so that the coating on the surface of the metal ball can be quickly dried to ensure the coating quality of the metal ball.

[0064] It is further explained that when the metal ball enters the induction heating component 6 after being sprayed with paint by the coating mechanism 3 under the action of the magnetic levitation mechanism 2, the sensor in the induction heating component 6 senses the entry of the metal ball, and the heating plates located on both sides of the metal ball begin to heat up, quickly drying the paint on the surface of the metal ball.

[0065] It is further explained that if multiple coating mechanisms 3 are provided, an induction heating component 6 should be provided at the rear end of each coating mechanism 3 to prevent the coating materials of the two coating mechanisms 3 at the front and rear from mixing and sticking together.

[0066] like Figure 1-Figure 2 As shown, the head end and the tail end of the coating pipe 31 are both provided with a light adjustment component 7 for making the metal ball vibrate slightly.

[0067] In this embodiment, the lighting condition of the light adjustment component 7 is adjusted to the optimal lighting state, and the light adjustment component 7 is arranged at the head end of the coating pipe 31, so that the metal ball can produce slight vibration under the condition of optimal lighting, and maintain this state to enter the coating pipe 31, so that the coating of the metal ball is sprayed more evenly and completely under the action of vibration; the light adjustment component 7 is arranged at the tail end of the coating channel, which is conducive to the metal ball to obtain more uniform heating by the induction heating component 6 in slight vibration, accelerates drying and ensures the quality of the metal ball.

[0068] It is further explained that, if a plurality of coating mechanisms 3 are provided, a light adjustment component 7 should be provided at the head end and the tail end of each coating mechanism 3 .

[0069] It is further explained that the light adjustment component 7 controls the vibration amplitude of the metal ball by adjusting the damping factor, thermal relaxation time, light intensity, light cycle and light time rate. The vibration equilibrium position can be adjusted by light intensity and thermal relaxation time, and the vibration response time can be controlled by thermal relaxation time and damping.

[0070] like Figure 5 As shown, the coating mechanism 3 also includes a solid coating material input assembly 32 connected to and installed on the coating pipeline 31 , and a collecting box 37 for collecting fallen solid coating material is installed on the lower side of the coating pipeline 31 corresponding to the solid coating material input assembly 32 .

[0071] In this embodiment, the solid coating input component 32 is preferably arranged behind the liquid coating input component 33. Under the action of the magnetic levitation mechanism 2, the metal ball moves forward and suspends through the coating pipe 31. In the coating pipe 31, it first passes through the liquid coating input component 33 and then passes through the solid coating input component 32, so that the sprayed solid coating can be evenly adhered to the metal ball, thereby improving the working efficiency.

[0072] It is further explained that the number and position of the solid coating input assembly 32 and the liquid coating input assembly 33 can be set on the coating pipeline 31 according to needs, and the metal ball is suspended and moved through the coating channel through the cooperation of the magnetic suspension mechanism 2 to spray the coating.

[0073] It is further explained that when the solid coating is sprayed on the metal balls, some waste will be generated. These wastes are collected and processed uniformly through the collection box 37 set at the corresponding position on the lower side of the coating pipeline 31, which is beneficial to the reuse of resources and the reduction of costs.

[0074] It is further explained that retaining rings are provided on both sides of the coating pipe 31 corresponding to the solid coating input assembly 32 to prevent the solid coating from falling into other positions of the coating pipe 31 to avoid affecting the spraying effect of the coating.

[0075] like Figure 5 As shown, the solid paint input component 32 includes: a solid paint pipeline 321 connected to the coating pipeline 31, a powder spray gun 322 installed on the top of the solid paint pipeline 321, and a first sensor 323 installed on the side wall of the solid paint pipeline 321 for detecting the solid paint spraying frequency.

[0076] The liquid coating input assembly 33 includes: a liquid coating pipeline 331 connected to the coating pipeline 31, a separating funnel 332 installed at the top of the liquid coating pipeline 331, and a second sensor 333 installed on the side wall of the liquid coating pipeline 331 for detecting the dripping frequency of the liquid coating. The dripping frequency of the liquid coating and the spraying frequency of the solid coating both correspond to the movement speed of the metal ball in the coating channel.

[0077] In this embodiment, the speed of dripping or spraying paint of the solid paint input component 32 and the liquid paint input component 33 is first set according to the movement speed of the magnetic suspension component 24, and the separatory funnel 332 and the powder spray gun 322 are controlled to drip or spray solid or liquid paint at the set frequency, so that when the metal ball passes through the position of the coating pipe 31 corresponding to the solid paint input component 32 and the liquid paint input component 33, the dripping or spraying liquid or solid paint can be received. This structure makes the operation of the device simpler and more convenient, and the waste of paint can be avoided through precise calculation.

[0078] It is further explained that the setting of the first sensor 323 is convenient for detecting the speed of solid spraying, and the setting of the second sensor 333 is convenient for detecting the speed of liquid spraying dripping. The setting of the first sensor 323 and the second sensor 333 can monitor the discharge frequency of the paint to prevent the phenomenon of empty operation.

[0079] like Figure 6-Figure 7 As shown, the feeding mechanism 4 includes a second motor 42 fixedly mounted on the base plate 1 through a motor mounting bracket 41, a feed gear 43 coaxially mounted with the output shaft of the second motor 42, a feed bin 44 sleeved on the outside of the feed gear 43, and a feed channel 45 installed at the bottom end of the feed bin 44.

[0080] The metal balls enter through the feed port opened at the top of the feed bin 44 , and are driven by the rotation of the feed gear 43 to roll out from the discharge port opened at the bottom of the feed bin 44 into the feed channel 45 , and continue to roll into the coating pipe 31 .

[0081] In this embodiment, the metal balls are placed in the feed bin 44 through the feed port, and the second motor 42 is started to rotate the feed gear 43 installed on the same output shaft as the second motor 42. The multiple metal balls are sent out from the discharge port in sequence through the rotation of the feed gear 43, and then the metal balls fall into the feed channel 45. Under the influence of inertia, the metal balls roll forward in the feed channel 45, enter the coating channel connected to the feed channel 45, and move forward through the action of the magnetic suspension mechanism 2.

[0082] It is further explained that the inner surface of the feed bin 44, the surface of the feed gear 43 and the inner surface of the feed channel 45 are all provided with a buffer layer for mitigating the impact of the falling metal balls and protecting the integrity of the metal balls.

[0083] It is further explained that the speed of the metal balls entering the feeding channel 45 is controlled by controlling the speed of the second motor 42 and thereby controlling the speed of the feeding gear 43 .

[0084] It is further explained that a pressure sensor 46 is provided at the position where the feed channel 45 is connected to the coating pipeline 31, for detecting the normal passage of the metal ball.

[0085] It is further explained that the feed channel 45 is preferably set to a plate-closed state, which is conducive to better operation of the light adjustment component 7.

[0086] like Figure 8 As shown, the unloading mechanism 5 includes: a third motor 51 installed on the base plate 1, a driving pulley 52 installed coaxially with the output shaft of the third motor 51, a driven pulley 54 rotating synchronously with the driving pulley 52 through a conveyor belt 53, and a discharge channel 55 installed corresponding to the coating mechanism 3 for receiving metal balls, the conveyor belt 53 is provided with a groove 531 adapted to the metal balls, the tail end of the discharge channel 55 corresponds to the groove 531, one end of the conveyor belt 53 is provided with a spiral falling channel 56 for receiving metal balls, and the tail of the spiral falling channel 56 is installed with a storage slot 57.

[0087] The metal balls fall into the groove 531 through the discharge channel 55 , and roll into the spiral falling channel 56 through the transmission of the conveyor belt 53 , and roll into the storage groove 57 along the spiral falling channel 56 .

[0088] In this embodiment, the metal balls are sent into the discharge channel 55 through the movement of the magnetic suspension component 24, and the third motor 51 is started, and the driving pulley 52 coaxially installed with the output shaft of the third motor 51 rotates accordingly, and drives the conveyor belt 53 installed with the driving pulley 52 to rotate, so that the metal balls in the discharge channel 55 fall into the groove 531 on the conveyor belt 53, and are transported to the spiral falling channel 56 by the conveyor belt 53, and finally roll into the storage groove 57 for storage.

[0089] It is further explained that the interior of the groove 531, the inner surface of the spiral falling channel 56 and the inner wall of the storage groove 57 are all provided with a buffer layer for mitigating the impact of the falling metal ball and allowing the metal ball to roll smoothly.

[0090] like Figure 1-Figure 8 As shown, the present invention also provides a method for preparing a non-contact metal ball rapid coating preparation device, comprising the following steps:

[0091] S1. Place the metal ball in the feeding mechanism 4;

[0092] S2. Under the action of the light adjustment component 7, the metal ball vibrates slightly and is driven by the magnetic suspension mechanism 2 into the coating pipe 31;

[0093] S3. The magnetic suspension mechanism 2 continues to move, driving the metal ball to move in the coating pipe 31, and when passing through the liquid coating input assembly 33, the liquid droplets suspended in the coating pipe 31 are coated on the surface of the metal ball;

[0094] S4. The magnetic suspension mechanism 2 continues to move, driving the metal ball to move out of the coating pipe 31. At this time, the induction heating component 6 senses the metal ball and emits heat, and the metal ball is quickly dried under the action of the heating component and the light adjustment component 7;

[0095] S5. The magnetic suspension assembly 24 continues to move, and the metal balls are fed into the unloading mechanism 5 to complete the preparation of the metal ball coating.

[0096] The preparation method using a non-contact metal ball rapid coating preparation device is as follows:

[0097] Put the metal ball into the feed bin 44, start the first motor 22, make the feed gear 43 rotate to transfer the metal ball to the feed channel 45, and make the metal ball vibrate slightly by the irradiation of the light adjustment component 7, and then make the metal ball suspend and move to the coating pipe 31 by the magnetic suspension mechanism 2. The metal ball suspends and moves through the coating pipe 31. When passing through the liquid coating input component 33, the liquid droplets suspended in the coating pipe 31 due to the acoustic suspension component 34 are coated on the surface of the metal ball; when passing through the solid coating input component 32, the solid coating sprayed by the powder spray gun 322 is bonded to the surface of the metal ball;

[0098] The metal ball is transferred to the induction heating assembly 6 through the movement of the magnetic levitation mechanism 2. At this time, the induction heating plate emits heat to quickly dry the paint sprayed on the surface of the metal ball. Then, the dried metal ball is moved forward to the discharge channel 55 through the action of the magnetic levitation mechanism 2, and then slides into the groove 531 on the conveyor belt 53. The metal ball is transferred to the spiral falling channel 56 through the conveyor belt 53, and finally rolls into the storage tank 57 for storage.

[0099] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the protection scope of the present invention.
