Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning, in particular to special equipment for laser cleaning of tire moulds. Background Art

[0002] Tire mold cleaning is usually done by sandblasting and ice blasting. Sandblasting uses compressed air as a power source to form a high-speed jet beam that sprays the material onto the workpiece surface at high speed, impacting and grinding away debris or rust attached to the workpiece surface. When dry ice is "sprayed" onto the surface, unwanted contaminants will freeze and break, and then an energy explosion will occur, thereby removing debris from the surface.

[0003] The above two forms of high-pressure and high-speed jetting use contact impact to remove impurities on the mold surface, but will cause changes in appearance or shape and damage the mold surface. In addition, the operator relies on experience to control the jet pressure by adjusting the distance between the nozzle head and the surface, which cannot be controlled evenly and can easily damage the material surface.

[0004] Laser cleaning equipment using pulsed fiber lasers can form high-energy lasers through short pulses to irradiate the surface of the material. The surface absorbs the laser energy and converts it into internal energy, causing the surface temperature to rise rapidly to above the vaporization temperature of the material, thereby allowing the pollutants to separate from the surface of the material in the form of steam. Non-contact cleaning does not require physical contact with the mold surface, thus avoiding damage to the mold and extending the service life of the mold. Therefore, laser cleaning equipment is now used to clean tire molds in more and more scenarios.

[0005] However, most existing laser cleaning devices for tire molds use a single set of clamping mechanisms to fix the mold before cleaning, which wastes a lot of time during the loading and unloading process, resulting in a decrease in cleaning efficiency. Therefore, in view of this, a special tire mold laser cleaning device is proposed to solve the above problem. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model proposes a special equipment for laser cleaning of tire molds to solve the technical problem raised in the above background technology that most of the existing laser cleaning devices for tire molds fix the molds through a single set of clamping mechanisms before cleaning, and a large amount of time is wasted during the loading and unloading process, thereby resulting in a decrease in cleaning efficiency.

[0035] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0036] Example:

[0037] like Figure 1 , 2 As shown, the utility model provides a tire mold laser cleaning special equipment, including a mounting track 101, a mounting seat 201 is slidably provided on the mounting track 101, a laser cleaning head 203 installed by a mechanical arm 202 is provided on the mounting seat 201, a walking mechanism connected to the mounting track 101 is provided on the mounting seat 201, and the mounting seat 201 is driven to slide on the mounting track 101 by the walking mechanism. The walking mechanism includes a first rack 105 arranged on one side of the mounting track 101 along the extending direction of the mounting track 101, a driving motor 204 is provided on the mounting seat 201, and a first gear 205 meshing with the first rack 105 is provided on the output shaft of the driving motor 204.

[0038] When the device is in use, the mechanical arm 202 can drive the laser cleaning head 203 to rotate with multiple degrees of freedom, and the tire mold can be cleaned by the laser cleaning head 203. The entire cleaning process of laser cleaning does not require physical contact with the mold surface, thereby avoiding damage to the mold and extending the service life of the mold. The first gear 205 can also be driven to rotate by controlling the drive motor 204. During the rotation process, the first gear 205 drives the mounting seat 201 to slide along the mounting track 101 as a whole through cooperation with the first rack 105, so as to drive the laser cleaning head 203 to move. Limit blocks 104 are provided at both ends of the mounting track 101. The limit blocks 104 are detachably installed to prevent the mounting seat 201 from detaching from the mounting track 101.

[0039] like Figure 2 , 3 As shown, in this embodiment, two groups of mounting shells 102 are arranged on one side of the mounting track 101, and a mold groove 103 is opened on the mounting shell 102, and a clamping mechanism is arranged in both groups of mold grooves 103. The clamping mechanism includes two groups of clamping plates 302 arranged opposite to each other, and both groups of clamping plates 302 are located in the mold groove 103. A second rack 301 is arranged on the connection of the clamping plates 302, and the second rack 301 passes through the mold groove 103 and is located in the mounting shell 102. An elastic member 303 abutting against the mounting shell 102 is arranged at the end of the second rack 301, and a second gear 304 is rotatably arranged in the mounting shell 102, and the second gear 304 is meshed with the two groups of second racks 301.

[0040] After the tire mold is placed in the mold groove 103, one group of the second racks 301 can be controlled to slide in the mounting shell 102 to drive one group of the clamping plates 302, and through the relative arrangement of the two groups of second racks 301 and the meshing relationship between the two groups of second racks 301 and the second gear 304, one group of the second racks 301 can control the other group of the second racks 301 to slide in the opposite direction during the movement, so that the two groups of clamping plates 302 can move in opposite directions to open and close, so as to clamp and fix the mold to be cleaned.

[0041] like Figure 2 , 3 As shown, in this embodiment, a driving assembly is provided on one of the second racks 301, and when the mounting seat 201 slides to one side of one of the mounting shells 102, the driving assembly drives one of the second racks 301 to slide in a direction away from the mounting seat 201. The driving assembly includes an abutment seat 305, which is detachably provided at the end of one of the second racks 301 and extends out of the mounting shell 102. The side wall of the abutment seat 305 is provided with an inclined surface, and the mounting seat 201 can abut against the end surface of the abutment seat 305.

[0042] In the initial state, the two sets of second racks 301 in one set of mounting shells 102 push the two sets of clamps 302 to be in an open state under the action of the elastic member 303. During the sliding process, the mounting seat 201 pushes the abutment seat 305 to move inward and retract into the mounting shell 102 through contact with the side wall inclined surface of the abutment seat 305, thereby driving the second rack 301 to slide and control the clamps 302 to clamp the tire mold to be cleaned. When the mounting seat 201 moves to one side of the other set of mounting shells 102 under the drive of the walking mechanism, the second rack 301 is reset under the action of the elastic member 303 to open the clamps 302, thereby eliminating the need for manual control of the clamping and fixing of the tire mold, further improving work efficiency. By setting the drive component, cleaning and mold loading and unloading can be carried out simultaneously, reducing time waste. Moreover, the abutment seat 305 is detachably installed, so that the abutment seat 305 of different sizes can be replaced according to the size of the tire mold, so as to facilitate the control of the clamping plates 302 to close at different distances, thereby improving the application range of the device.

[0043] Specific usage and beneficial effects of the utility model:

[0044] When the device is in use, the tire mold to be cleaned is placed in the mold groove 103, and the mounting seat 201 is moved to cooperate with the inclined surface of the abutting seat 305 to push the abutting seat 305 to slide, so that one set of second racks 301 slides in the mounting shell 102, and the cooperation of the second rack 301 and the second gear 304 drives the two sets of clamping plates 302 to close and fix the tire mold, and the tire mold can be cleaned in all directions through the cooperation of the mechanical arm 202 and the laser cleaning head 203. After the cleaning of the tire mold in one set of mold grooves 103 is completed, the mounting seat 201 can be controlled to slide on the mounting track 101, so that the mounting seat 201 moves to one side of another set of mounting shells 102 to clean the tire mold in the other set of mounting shells 102, and the cleaned set of tire molds can be replaced while cleaning, so that the cleaning and loading and unloading of the tire mold can be carried out simultaneously, which effectively improves the work efficiency when cleaning the mold.
