[0024] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0026] Combine Figure 1-4 As shown, an automated laser cleaning device comprises:

[0027] The base 1 is a cylindrical structure that supports the bottom of the entire device. A turntable 11 is movably mounted on the top surface. A drive motor 12 is embedded in the center of the top surface of the base 1. The output end of the drive motor 12 is vertically upward and fixedly connected to the center of the bottom surface of the turntable 11.

[0028] The fixed frame 2 is provided on the station on the top surface of the turntable 11 and is used to place the mold to be cleaned;

[0029] The clamping assembly 3 is arranged inside the fixing frame 2 and is used to clamp and fix the mold to be cleaned so as to transport it from the loading station to the vicinity of the cleaning station;

[0030] The turning assembly 4 is provided on both sides of the fixing frame 2 and is used to cooperate with the fixing frame 2 to automatically turn over the mold for cleaning;

[0031] The laser cleaning machine 5 is an existing laser cleaning device, which is arranged above the turntable 11 through a structure such as a bracket or a robotic arm, and its laser cleaning head is arranged vertically downward toward one of the workstations on the top surface of the turntable 11. The laser cleaning head at the bottom of the device can move horizontally to cover and clean the mold surface on the workstation.

[0032] Specifically, the turntable 11 is provided with a total of 4 stations and arranged in a circular array. One of the stations is always aligned with the laser cleaning machine 5 in an up-and-down manner and serves as a processing station. The loading station is symmetrically arranged with the processing station, and the unloading station is located on one side of the processing station. Therefore, the turntable 11 can be rotated so that the loading station can transport the mold to be cleaned to the vicinity of the laser cleaning machine 5 in turn. After cleaning, the mold is transported to the unloading station, thereby realizing continuous and uninterrupted cleaning processing and improving production efficiency.

[0033] In the above structure, an auxiliary bracket 6 is provided at the bottom of the loading station. The auxiliary bracket 6 is spaced apart from the base 1 and a support plate is provided on the top surface.

[0034] The workstations on the turntable 11 are all set as rectangular openings, and the fixed frame 2 is correspondingly set as a rectangle and arranged horizontally at the center of the workstation, with a gap between the four sides and the inner wall of the workstation. The fixed frame 2 is mainly connected to the workstation by the flip components 4 arranged on both sides.

[0035] Therefore, in the actual material feeding process, the fixed frame 2 is first arranged in a horizontal state, and then moved to the top surface of the support plate, and then the mold to be cleaned is placed in it. In this structure, the support plate should maintain a small distance from the horizontal fixed frame 2, so that when the bottom of the mold abuts against the support plate, most of it is inside the fixed frame 2, ensuring that its side walls can be clamped and fixed.

[0036] The clamping assembly 3 includes a clamping block 31 and an adjusting ring 32, wherein the fixed frame 2 is a rectangular frame with a circular through hole in the center and a slide groove 21 on the surface. There are four slide grooves 21 arranged in a circular array. There are four clamping blocks 31 correspondingly and they are respectively installed in the four slide grooves 21 so that the mold can be fixed by synchronous clamping on the four sides.

[0037] In the above structure, the interior of the fixed frame 2 should be set to be hollow, and the adjusting ring 32 is rotatably installed inside the fixed frame 2 through the ball bearing 33 installed at the center, and the inner ring surface of the ball bearing 33 is sleeved on the side wall of the through hole, for example Figure 4 As shown, a gap is left between the inner bottom surface of the fixing frame 2 and the bottom surface of the adjusting ring 32 .

[0038] The slide groove 21 part extends downward and is connected with the interior of the fixed frame 2, so the bottom of the clamping block 31 extends downward into the interior of the fixed frame 2, and the top surface of the adjusting ring 32 is also provided with a vortex-shaped groove, and the protruding part of the bottom surface of the clamping block 31 is just inserted into the interior of the groove to form a chuck structure. The arc-shaped internal part of the top surface of the adjusting ring 32 is used to drive the clamping block 31 to move along the slide groove 21, so that the four sides can fix its side walls synchronously, and it can also have a certain centering effect. Therefore, the mold only needs to be placed inside the through hole, and there is no need for staff to recalibrate and position it at the laser cleaning machine 5.

[0039] A driving structure is provided on the bottom surface of the adjusting ring 32, which is a worm gear 34 and worm 35 structure, that is, the worm gear 34 is fixedly mounted on the bottom surface of the adjusting ring 32, and the worm 35 is longitudinally arranged on one side of the worm gear 34 and is transmission-connected to the worm gear 34, and the two ends of the worm 35 are respectively transmission-connected to the protruding parts on the inner bottom surface of the fixed frame 2. A servo motor 36 is also provided inside the fixed frame 2, and the output end of the servo motor 36 should be transmission-connected to one end of the worm 35.

[0040] During the clamping process of the clamping block 31, in order to avoid damage to the side wall of the mold due to excessive clamping force, an elastic layer can be set on the side wall surface. The elastic layer can be made of elastic materials such as rubber pads or silicone pads, and the side wall of the elastic layer can be set to a corrugated structure to enhance the friction between the mold and the mold.

[0041] The flipping assembly 4 includes a connecting shaft 41 arranged on both sides of the fixed frame 2. The two ends of the connecting shaft 41 extend toward the two side walls of the workstation and are rotatably connected to its side walls. An electric motor 42 is also provided inside the turntable 11. The electric motor 42 is transmission-connected to the end of one of the connecting shafts 41, thereby utilizing the connecting shaft 41 to drive the entire fixed frame 2 to flip, and the flipping angle each time is 90°.

[0042] The drive motor 12, servo motor 36 and electric motor 42 in the above structure can all be equipped with a Bluetooth module, and the Bluetooth module can be connected to a remote control device so as to be programmed and controlled to realize automated operation, further improve production efficiency and reduce the labor intensity of staff.

[0043] In addition, a counter is provided at the bottom of the laser head of the laser cleaning machine 5. The transmitting end of the counter is arranged vertically downward, and a reflecting end is correspondingly provided on the top surface of the turntable 11. The reflecting end is arranged close to one of the workstations. The transmitting end of the counter continuously transmits the model downward, and is reflected back through the reflecting end and receives the signal, which is recorded. By recording the number of reflected signals and combining it with the number of workstations, the production quantity of the mold can be quickly obtained so that the staff can check the production indicators.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
