Description

Technical Field

[0001] This utility model relates to the field of coloring spray gun technology, specifically to an automated button coloring spray gun module that facilitates nozzle replacement. Background Technology

[0002] Existing automated button coloring spray gun modules typically consist of a conveyor table and a fixed spray gun, used to achieve batch and automated spraying and coloring of buttons arranged on a material tray. This replaces traditional manual spraying, improving production efficiency and coating uniformity.

[0003] Existing devices of this type typically feature a drive module that can move in two or three dimensions above a conveyor platform, with a fixed spray gun mounted at its end. The spray gun is connected to a remote material supply system and air source via piping. When it is necessary to change the spray head to accommodate different colors, paints, or spraying precision requirements, the operator must manually unscrew the old spray head, clean the interface, and then install the new spray head. The entire replacement process is manual.

[0004] The shortcomings of the existing technology are that the replacement efficiency is extremely low, manual unscrewing and installation are time-consuming and labor-intensive, seriously affecting the production cycle, and cannot achieve batch and automated spraying and coloring management of buttons, requiring manual intervention.

[0005] Therefore, we propose an automated button coloring spray gun module with easy nozzle replacement to solve the problems mentioned above. Utility Model Content

[0006] This utility model provides an automated button coloring spray gun module that facilitates nozzle replacement. It can solve the problem in the prior art where operators have to replace the nozzles to adapt to different colors, paints, or spraying precision requirements, making it impossible to achieve batch and automated spraying and coloring management of buttons.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An automated button coloring spray gun module with easy nozzle replacement includes a conveyor table with a U-shaped frame mounted on it. A nozzle storage plate is fixedly installed inside one side of the U-shaped frame, and magnetic suction slots matching the nozzle shape are linearly and equidistantly arranged on the nozzle storage plate. A movement control component is installed inside the other side of the U-shaped frame, including a transverse drive rail and a longitudinal drive rail. The transverse drive rail is installed inside the upper end of the U-shaped frame, and the longitudinal drive rail slides in conjunction with the transverse drive rail. An electric telescopic rod is located below the longitudinal drive rail, and a mounting base is provided at the telescopic end of the electric telescopic rod. A quick-change spraying assembly is fixedly installed on the mounting base. The quick-change spraying assembly includes a spray gun, an adapter, and a nozzle body. The adapter is installed at the discharge end of the spray gun, and the nozzle body is detachably mounted on the adapter. A strong electromagnetic suction ring is fixedly installed at the end of the adapter away from the spray gun, and the nozzle body is made of a material that can be magnetically attracted.

[0008] Preferably, the adapter is cylindrical and has an internal discharge channel, which is fixedly connected to the discharge end of the spray gun.

[0009] Preferably, the nozzle body has a connector at the feed end, the connector has a feed hole inside, and the outer diameter of the connector is tightly fitted with the discharge channel inside the adapter.

[0010] Preferably, the adapter is provided with locking components on both sides inside, and the connector is provided with positioning holes on both sides that cooperate with the locking components.

[0011] Preferably, the locking assembly includes telescopic cavities disposed on both sides inside the adapter, a piston slider is slidably fitted inside the telescopic cavity, a return spring is disposed between one end of the telescopic cavity and the piston slider, a hydraulic cavity is disposed at one end of the telescopic cavity, and a hydraulic pipe is fixedly connected to the bottom of the hydraulic cavity.

[0012] Preferably, a locking pin is fixedly connected to the side of the piston slider away from the return spring. The locking pin passes through the interior of the adapter and extends into the discharge channel. When the connector is inserted into the discharge channel of the adapter, the return spring pushes the piston slider, causing the locking pin to be inserted into the positioning hole.

[0013] Preferably, a material tray is placed on the conveyor table, and button slots for placing buttons are evenly distributed on the upper part of the material tray.

[0014] Preferably, the nozzle body is made of stainless steel.

[0015] Preferably, the longitudinal drive rail is slidably connected to the transverse drive rail via a slider, thereby enabling the transverse drive rail to drive the longitudinal drive rail to slide laterally.

[0016] Preferably, the inner surface material of the magnetic suction groove is different from that of the nozzle storage plate body; it is a permanent magnet material or a metal material that can be magnetically attracted.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are: I. This utility model uses a mobile control component to drive a quick-change spraying assembly to the nozzle storage plate. The current nozzle body is released into the magnetic slot by de-energizing the strong electromagnetic chuck. Subsequently, the mobile control component moves the adapter to the top of another magnetic slot, where the strong electromagnetic chuck is energized to attract the new nozzle body, completing the automatic replacement. Specifically, by utilizing the on / off control of the strong electromagnetic chuck, combined with the mechanical locking and hydraulic unlocking mechanism of the locking component, precise switching and secure installation of different nozzles can be completed within seconds without manual intervention. This completely solves the problems of low efficiency and production interruption caused by manual replacement, significantly improving the automation level of multi-color, multi-process button production.

[0018] Second, this utility model ensures the sealing of the spraying channel through the tight fit between the adapter and the connector, and achieves precise workpiece positioning through the button slots on the material tray. This allows the motion control component to drive the replaced spray head body to perform batch, orderly, and precise automated coloring of the buttons on the conveyor table. This not only ensures extremely high coating uniformity and pattern accuracy but also effectively avoids paint leakage and positional drift. Ultimately, while improving product quality consistency, it significantly reduces labor costs and operational errors. Attached Figure Description

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] Please see Figure 1-4 This utility model provides a technical solution: An automated button coloring spray gun module 51 with easy nozzle replacement includes a conveyor table 1, a U-shaped frame 2 installed on the conveyor table 1, a nozzle storage plate 3 fixedly installed inside one side of the U-shaped frame 2, magnetic suction grooves 31 matching the shape of the nozzles are linearly and equidistantly arranged on the nozzle storage plate 3, and a movement control component 4 installed inside the other side of the U-shaped frame 2. The movement control component 4 includes a transverse drive rail 41 and a longitudinal drive rail 42. The transverse drive rail 41 is installed inside the upper end of the U-shaped frame 2, and the longitudinal drive rail 42 slides with the transverse drive rail 41. An electric telescopic rod 43 is provided below the longitudinal drive rail 42, and a mounting seat 44 is provided at the telescopic end of the electric telescopic rod 43. A quick-change spraying component 5 is fixedly installed on the mounting seat 44. The quick-change spraying assembly 5 includes a spray gun 51, an adapter 52, and a nozzle body 53. The spray gun 51 is equipped with an adapter 52 at its discharge end, and the nozzle body 53 is detachably mounted on the adapter 52. A strong electromagnetic suction ring 66 is fixedly installed at the end of the adapter 52 away from the spray gun 51. The nozzle body 53 is made of a material that can be magnetically attracted, so that the nozzle body 53 can be attracted and fixed in the magnetic groove 31 of the adapter 52 or the nozzle storage plate 3.

[0023] In the above solution, the quick-change spraying assembly 5 is moved to the nozzle storage plate 3 by the motion control component 4. The strong electromagnetic suction ring 66 is energized and de-energized to achieve rapid adsorption and release of the nozzle body 53 between the adapter 52 and the magnetic suction groove 31, thus completing the automatic nozzle replacement. During spraying, the nozzle body 53 is firmly adsorbed on the adapter 52, and the motion control component 4 moves it precisely to the material tray 11 above the conveyor table 1 for automated coloring of the buttons. This solution effectively solves the technical problems of low nozzle replacement efficiency, reliance on manual replacement, and loss of positioning accuracy caused by frequent replacements in the existing technology.

[0024] In some specific implementations, the adapter 52 is cylindrical and has an internal discharge channel, which is fixedly connected to the discharge end of the spray gun 51.

[0025] The adapter 52 is cylindrical and has an internal discharge channel, which allows the paint from the spray gun 51 to flow smoothly and centrally to the nozzle body 53. This structure facilitates the installation and positioning of the nozzle body 53.

[0026] In some specific implementations, the feed end of the nozzle body 53 is provided with a connector 54, the connector 54 has a feed hole inside, and the outer diameter of the connector 54 is tightly fitted with the discharge channel inside the adapter 52.

[0027] The nozzle body 53 is tightly inserted into the discharge channel of the adapter 52 through the connector 54 at its feed end. Before the strong electromagnetic suction ring 66 adsorbs and fixes it, the nozzle body 53 is pre-positioned and centered, and a sealed channel for the paint to flow from the adapter 52 to the nozzle body 53 is formed to prevent paint leakage.

[0028] In some specific implementations, locking components 6 are provided on both sides inside the adapter 52, and positioning holes 55 that cooperate with the locking components 6 are provided on both sides of the connector 54.

[0029] A locking component 6 is provided inside the adapter 52 and cooperates with the positioning hole 55 on the connector 54. When the connector 54 is inserted into the position, the locking component 6 can automatically or passively lock into the positioning hole 55 to achieve mechanical locking of the nozzle body 53. This forms a double insurance with the magnetic fixing method, which greatly enhances the reliability and impact resistance of the connection.

[0030] Example 2: Please see Figure 1-4 Furthermore, in conjunction with Example 1, we obtain that, In some specific implementations, the locking component 6 includes telescopic cavities 61 disposed on both sides inside the adapter 52. A piston slider 62 is slidably fitted inside the telescopic cavity 61. A return spring 64 is disposed between the outer end of the telescopic cavity 61 and the piston slider 62. A hydraulic cavity is disposed at the inner end of the telescopic cavity 61. A hydraulic pipe 65 is fixedly connected to the bottom of the hydraulic cavity.

[0031] The locking assembly 6 injects hydraulic oil into the hydraulic chamber through the hydraulic pipe 65, which pushes the piston slider 62 to move outward against the elastic force of the return spring 64, thereby causing the locking pin 63 to exit from the positioning hole 55 and achieve unlocking; when locking is required, the hydraulic pressure is removed, and the return spring 64 pushes the piston slider 62 and the locking pin 63 to insert into the positioning hole 55 to complete the mechanical locking. This process achieves stable hydraulic pressure control.

[0032] In some specific implementations, a locking pin 63 is fixedly connected to the side of the piston slider 62 away from the return spring 64. The locking pin 63 passes through the interior of the adapter 52 and extends into the discharge channel. When the connector 54 is inserted into the discharge channel of the adapter 52, the return spring 64 pushes the piston slider 62, causing the locking pin 63 to be inserted into the positioning hole 55.

[0033] The piston slider 62 pushes the locking pin 63 into the positioning hole 55 of the connector 54 through the elastic force of the return spring 64, realizing automatic mechanical locking of the nozzle body 53 during installation, ensuring the immediacy and stability of the connection; while unlocking is completed by hydraulic drive.

[0034] In some specific implementations, a material tray 11 is placed on the conveyor table 1, and button slots 12 for placing buttons are evenly distributed on the upper part of the material tray 11.

[0035] The material tray 11 on the conveyor 1 is provided with evenly distributed button slots 12. Each button slot 12 is used to accurately accommodate and position a single button, thereby ensuring that the button is fixed in position during the spraying process, so that the quick-change spraying assembly 5 can perform batch, orderly and precise spraying operations.

[0036] In some specific implementations, the nozzle body 53 is made of stainless steel.

[0037] The nozzle body 53 is made of stainless steel, which gives it good magnetization properties. It can be firmly attracted by the strong electromagnetic ring 66 on the adapter 52 and the magnetic groove 31 on the nozzle storage plate 3. At the same time, stainless steel has excellent wear resistance and corrosion resistance to adapt to the coating environment and extend its service life.

[0038] In some specific implementations, the longitudinal drive rail 42 is slidably connected to the transverse drive rail 41 via a slider, thereby enabling the transverse drive rail 41 to drive the longitudinal drive rail 42 to slide laterally. The longitudinal drive rail 42 is slidably connected to the transverse drive rail 41 via a slider, so that the transverse drive rail 41 can drive the entire longitudinal drive rail 42 and the components below it to move laterally together during operation, thereby achieving precise composite positioning of the quick-change spraying assembly 5 in the horizontal plane in both the transverse and longitudinal directions.

[0039] In some specific implementations, the inner surface material of the magnetic groove 31 is different from that of the nozzle storage plate 3 body. It is a permanent magnet material or a metal material that can be magnetically attracted, so as to enhance the positioning and holding force of the nozzle body 53.

[0040] The working principle of the button-type automatic coloring spray gun module 51, which facilitates nozzle replacement, is as follows: First, the movement control component 4 drives the quick-change spraying component 5 to move to the nozzle storage plate 3. The current nozzle body 53 is released into the magnetic suction slot 31 by de-energizing the strong electromagnetic suction ring 66. Then, the movement control component 4 drives the adapter 52 to move above another magnetic suction slot 31. The strong electromagnetic suction ring 66 is energized to attract the new nozzle body 53, thus completing the automatic replacement. During the spraying operation, the connector 54 of the nozzle body 53 is inserted into the discharge channel of the adapter 52 to achieve pre-positioning. The return spring 64 pushes the piston slider 62 to insert the locking pin 63 into the positioning hole 55 to achieve mechanical locking. At the same time, the strong electromagnetic suction ring 66 is energized to generate magnetic force to achieve secondary adsorption and fixation, forming a double insurance. Finally, the movement control component 4 moves the locked nozzle body 53 to above the material tray 11. The electric telescopic rod 43 adjusts the spraying height. The spray gun 51 delivers paint through the discharge channel and connector 54 and sprays it out from the nozzle body 53 to accurately and automatically color the buttons in the button slot 12.

[0041] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
