Technical Field
[0001] This utility model belongs to the technical field of cleaning guns for high-frequency pulsed laser cleaning machines, and specifically relates to a protective built-in structure for a cleaning gun for a high-frequency pulsed laser cleaning machine. Background Technology
[0002] High-frequency pulsed laser cleaning machines are widely used in industrial manufacturing. They precisely remove surface contaminants (oxide layers, paint, oil stains) using high-energy pulsed laser beams. The specific working principle is as follows: the metal substrate and the oxide layer, paint, or oil stains have different absorption rates for specific wavelengths of laser light. For example, the aluminum alloy oxide layer has an absorption rate of up to 80% for 1064nm laser light, while the substrate only absorbs 30%. This difference causes the contaminants to preferentially absorb energy, instantly vaporizing upon absorption. The high-energy laser breaks down the air to form plasma, generating shock waves that shatter the contaminants. Due to the difference in expansion coefficients between the contaminants and the substrate, they peel off, thus achieving the purpose of cleaning the contaminants. High-frequency pulsed laser cleaning machines offer advantages such as fast cleaning speed, non-contact operation, avoidance of damage to the substrate surface, and no chemical waste, making them suitable for cleaning contaminants on the surface of precision parts.
[0003] Currently used high-frequency pulsed laser cleaning machines typically have their cleaning heads coiled around one side or top of the machine body, completely exposed to the outside environment. The cleaning head includes a handle, galvanometer, and field lens. The handle is connected to a pulsed laser via an optical fiber, which provides pulsed laser light to the cleaning head. In existing technology, the cleaning head of a high-frequency pulsed laser cleaning machine is completely exposed to the outside environment. The main technical problem is that high-frequency pulsed laser cleaning machines are usually used in high-dust workshop environments, and dust can easily enter the galvanometer, field lens, and optical structure of the cleaning head, thus affecting the normal cleaning of contaminants. Based on the above-mentioned technical deficiencies in existing technology, the inventors have developed a protective built-in structure for the cleaning gun of a high-frequency pulsed laser cleaning machine, which effectively solves the aforementioned technical problems.

A touch switch is fixedly installed at the upper middle of the front side of the sheet metal housing. A coiled placement platform is fixedly installed at the center of the hollow housing, and the cleaning gun is placed at the upper middle of the coiled placement platform.
[0006] The sheet metal housing includes a housing body, with a top opening at the upper center of the housing body for fixing and installing a cleaning gun placement device; the four outer walls of the hollow housing are fixedly connected to the inner wall of the top opening; a touch switch is fixedly installed at the upper middle position of the front side of the housing body, and the bottom of the touch switch extends into the interior of the housing body.
[0007] The first and second shelves are square in shape, formed by welding four square tubes. The front and rear ends of the square tubes of the first and second shelves are fixedly installed on the front and rear inner side walls of the shell body.
[0008] The bottom of the lifting door panel and the upper end face of the hollow shell box are reserved for opening and closing.
[0009] The coiled placement platform includes a semi-circular coil body one, and semi-circular coil body one and semi-circular coil body two are semi-circular with convex edges on the upper and lower end faces. Semi-circular coil body one and semi-circular coil body two are fixed at the bottom center position inside the hollow shell box. The foam body is fixedly placed in the middle position of semi-circular coil body one and semi-circular coil body two. The arc-shaped placement groove is opened laterally in the middle position of the upper part of the foam body. The semi-circular groove is symmetrically opened in the middle position of the upper part of the foam body. The semi-circular groove and the arc-shaped placement groove are connected. The cleaning gun is placed in the arc-shaped placement groove.
[0010] The heights of the first and second semi-circular disk windings are greater than the height of the foam body.
[0011] After the convex edges of the upper and lower end faces of the first and second semi-circular disc windings are fixedly combined, a notch is formed in the middle of the horizontal direction of the foam body to facilitate the placement of the cleaning gun.

At this time, the telescopic rods of the symmetrically arranged electric push rods extend, pushing the lifting door panel upwards axially around the hinge. The operator then removes the cleaning gun from the arc-shaped placement groove of the foam body on the placement platform and removes the connected optical fiber from the middle position of the upper and lower convex edges of the semi-circular disc body one and two. Finally, the operator presses the switch of the cleaning gun, aligns it with the surface of the metal substrate to be cleaned, and uses the high-frequency pulsed laser to clean the oxide layer, paint, or oil stains from the surface of the metal substrate. After the contaminants on the surface of the metal substrate are laser cleaned, the cleaning gun needs to be placed back into the sheet metal housing; the above steps are repeated in reverse.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model provides a protective built-in structure for a cleaning gun used in a high-frequency pulsed laser cleaning machine:
[0024] like Figure 1As shown, the omnidirectional casters 1 are fixedly installed at the four bottom corners of the sheet metal shell 2, which is a hollow square body. Shelf 1 3 is fixedly installed inside the sheet metal shell 2 near the bottom, and shelf 2 4 is fixedly installed above shelf 1 3. The pulsed laser 5 is fixedly installed at the bottom inside the sheet metal shell 2, and the control system 6 is fixedly installed above shelf 1 3. The human-machine interface panel 7 is fixedly installed at the upper front side of the sheet metal shell 2. The cooling fans 8 are arranged in two groups, one group is fixedly installed at the corresponding position of the pulsed laser 5, and the other group is fixedly installed at the corresponding position of the control system 6. The cooling fans 8 are fixedly installed on the inner rear wall of the sheet metal shell 2. The built-in drawer 9 is fixedly installed above shelf 2 4, and the built-in drawer 9 is in contact with the upper surface of shelf 2 4.
[0025] The above structure describes the specific structure of a high-frequency pulsed laser cleaning machine. The omnidirectional casters 1 facilitate the movement of the high-frequency pulsed laser cleaning machine during laser cleaning of contaminants on the surface of metal substrates. The main purposes of the shelves 3 and 4 are: firstly, to provide a platform for the pulsed laser 5, control system 6, and built-in drawer 9 to be installed and fixed; secondly, to create a well-ventilated interlayer structure between the pulsed laser 5, control system 6, and built-in drawer 9, thereby improving the cooling effect on the pulsed laser 5, control system 6, and cleaning gun 1010.
[0026] like Figure 2 As shown, the cleaning gun placement device 10 includes a hollow shell box 101, which is a hollow square body with an open top and closed sides. The four outer walls of the hollow shell box 101 are fixedly connected to the sheet metal shell box 2. A bent plate 102 is fixedly installed inside the hollow shell box 101 at the upper rear side. A lifting door plate 103 is installed on the upper part of the hollow shell box 101. Hinges 104 are symmetrically fixedly installed on the upper part of the bent plate 102, and the lower rear end of the lifting door plate 103 is fixedly connected to the upper part of the hinge 104. A fixing plate 105 is symmetrically fixedly installed on the bottom of the lifting door plate 103. At the rear, the fixing base 106 is symmetrically fixed at the bottom front of the hollow shell box 101; the electric push rod 107 is symmetrically set at the left and right sides of the hollow shell box 101 at an angle, the telescopic rod end of the electric push rod 107 is fixed to the outside of the fixing plate 105, and the cylinder end of the electric push rod 107 is fixed on the fixing base 106; the touch switch 108 is fixedly set at the upper middle position of the front side of the sheet metal shell box 2; the coiled placement platform 109 is fixedly set at the center of the hollow shell box 101, and the cleaning gun 1010 is placed at the upper middle position of the coiled placement platform 109.
[0027] The hollow shell 101 provides a sealed space for the fixed installation of the coiled placement platform 109. On the one hand, it prevents dust from the laser cleaning site from entering the hollow shell 101 and contaminating the galvanometer or field mirror of the cleaning gun 1010. On the other hand, it forms a built-in protective structure for coiling and placing the cleaning gun 1010, and the cooling fan 8 in the high-frequency pulsed laser cleaning machine can be used to cool the cleaning gun 1010.
[0028] The above-mentioned arrangement of bending plate 102, lifting door panel 103, and hinge 104, with hinge 104 as the lifting and opening axis, realizes the lifting and opening action of lifting door panel 103.
[0029] The above-mentioned arrangement of fixed plate 105, fixed base 106, electric push rod 107 and touch switch 108, with touch switch 108 controlling the extension and retraction of electric push rod 107, thereby realizing the automatic lifting and opening of lifting door panel 103.
[0030] By using the setting of the coiled placement platform 109, and utilizing the limiting effect of the upper and lower convex edges of the semi-circular coil body one 1091 and the semi-circular coil body two 1092, the connecting optical fiber between the cleaning gun 1010 and the pulsed laser 5 can be coiled on the semi-circular coil body one 1091 and the semi-circular coil body two 1092 before the cleaning gun 1010 is placed, thus realizing the retraction of the fiber laser transmission line.
[0031] like Figure 1 As shown, the sheet metal housing 2 includes a housing body 21, and a top opening 22 for fixing and installing the cleaning gun placement device 10 is provided at the upper center of the housing body 21; the four outer walls of the hollow housing 101 are fixedly connected to the inner wall of the top opening 22.
[0032] The above-mentioned top opening 22 is opened at the top of the shell body 21, which is mainly used to install the cleaning gun placement device 10. The cleaning gun placement device 10 can be placed inside the sheet metal shell 2, forming a protective built-in structure for the cleaning gun.
[0033] like Figure 3 and Figure 4As shown, the coiled placement platform 109 includes a first semi-circular coil body 1091. The first semi-circular coil body 1091 and the second semi-circular coil body 1092 are semi-circular with protruding edges on their upper and lower end faces. The first semi-circular coil body 1091 and the second semi-circular coil body 1092 are fixed at the bottom center position inside the hollow shell box 101. The foam body 1093 is fixedly placed in the middle position between the first semi-circular coil body 1091 and the second semi-circular coil body 1092. The arc-shaped placement groove 1094 is laterally opened in the upper middle position of the foam body 1093. The semi-circular groove 1095 is symmetrically opened in the upper middle position of the foam body 1093. The semi-circular groove 1095 and the arc-shaped placement groove 1094 are connected. The cleaning gun 1010 is placed in the arc-shaped placement groove 1094.
[0034] The above-mentioned arrangement of the semi-circular disk winding body 1091, the semi-circular disk winding body 1092, and the upper and lower end face protrusions, combined with the foam body 1093, forms a space for winding the connecting optical fiber between the cleaning gun 1010 and the pulsed laser 5.
[0035] The aforementioned structure, featuring foam body 1093 and arc-shaped placement groove 1094, with the depth of arc-shaped placement groove 1094 greater than the diameter of cleaning gun 1010 and the length of arc-shaped placement groove 1094 less than the length of cleaning gun 1010, allows the cleaning gun 1010 to be completely placed in the arc-shaped placement groove 1094. The flexibility of foam body 1093 provides protection for the cleaning gun 1010.
[0036] The aforementioned arrangement of the foam body 1093 and the symmetrically arranged semi-circular grooves 1095, along with the structural feature that the semi-circular grooves 1095 are connected to the arc-shaped placement groove 1094, allows a person's hand to penetrate into the symmetrically arranged semi-circular grooves 1095, thus facilitating the handling of the cleaning gun 1010.
[0037] like Figure 3 As shown, the heights of the first semi-circular body 1091 and the second semi-circular body 1092 are greater than the height of the foam body 1093. The main purpose of this arrangement is to make the foam body 1093 sink into the center of the first semi-circular body 1091 and the second semi-circular body 1092, thereby protecting the foam body 1093 and preventing it from being damaged.
[0038] like Figure 1-4As shown, the working process of the protective built-in structure of the cleaning gun of this high-frequency pulsed laser cleaning machine is as follows: When it is necessary to use the high-frequency pulsed laser cleaning machine to laser clean contaminants on the surface of the metal substrate, the operator first starts the high-frequency pulsed laser cleaning machine, and then presses the touch switch 108 of the cleaning gun placement device 10. At this time, the telescopic rods of the electric push rods 107 arranged symmetrically on the left and right begin to extend, pushing the lifting door plate 103 to rise axially with the hinge 104 as the center. At this time, the operator takes the cleaning gun 1010 out of the arc-shaped placement groove 1094 of the foam body 1093 of the coiled placement platform 109, and takes out the optical fiber connected to it from the middle position of the upper and lower convex edges of the semi-circular winding body one 1091 and the semi-circular winding body two 1092. Finally, the operator presses the switch of the cleaning gun 1010, aligns it with the surface of the metal substrate to be cleaned, and uses the high-frequency pulsed laser to clean the oxide layer, paint or oil stains on the surface of the metal substrate. After the contaminants on the surface of the metal substrate have been cleaned by laser, the cleaning gun 1010 needs to be placed into the sheet metal housing 2. The opposite action described above can be repeated.
[0039] Various modifications to the above embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
