[0022] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0023] Reference below Figure 1 A laser cleaning apparatus according to an embodiment of the present invention is described.

[0024] like Figure 1 As shown, the laser cleaning device according to the embodiment of the present invention includes an object support 1 , a cleaning chamber 2 and a laser irradiation lamp 3 .

[0025] The object support 1 is used to place the object to be cleaned and place the object to be cleaned in the cleaning chamber 2. The inner wall of the cleaning chamber 2 is provided with a laser irradiation lamp 3, which is used to irradiate laser light to the object to be cleaned in the cleaning chamber 2. One of the object support 1 and the cleaning chamber 2 can rotate relative to the other.

[0026] When the laser cleaning device is in use, the object to be cleaned is placed in the cleaning chamber 2 through the object holder 1, and one of the object holder 1 and the cleaning chamber 2 is driven to rotate relative to the other, so that the laser irradiation lamp 3 surrounds the object to be cleaned and irradiates the object to be cleaned with a laser, thereby cleaning the object to be cleaned.

[0027] The laser cleaning equipment of the embodiment of the present invention has a laser irradiation lamp on the inner wall of the cleaning chamber, and the object holder is used to place the object to be cleaned in the cleaning chamber. The object holder and the cleaning chamber are rotatable relative to the other, so that the laser irradiation lamp can surround the object to be cleaned and fully irradiate the object to be cleaned. Therefore, the cleaning effect of the laser cleaning equipment of the embodiment of the present invention is better.

[0028] In some embodiments, there are at least two laser irradiation lamps 3 , and the at least two laser irradiation lamps 3 are arranged at intervals around the rotation axis of one of the object support 1 and the cleaning chamber 2 relative to the other.

[0029] like Figure 1 As shown, one of the article support 1 and the cleaning chamber 2 can rotate relative to the other in the left-right direction, and the inner wall of the cleaning chamber 2 is provided with at least two laser irradiation lamps 3, preferably but not limited to seven laser irradiation lamps 3, and the seven laser irradiation lamps 3 are arranged at intervals in the left-right direction, preferably but not limited to equidistant arrangement. The laser irradiation lamp 3 can be arranged on the inner wall surface of the cleaning chamber 2, or embedded in the inner wall of the cleaning chamber 2, or installed on the inner wall of the cleaning chamber 2 through a bracket, in which case there can be a gap between the laser irradiation lamp 3 and the inner wall surface of the cleaning chamber 2.

[0030] At least two laser irradiation lamps 3 are used to continuously irradiate the object to be cleaned. At the same time, when one of the object holder 1 and the cleaning chamber 2 rotates relative to the other, each laser irradiation lamp 3 surrounds the object to be cleaned, so that the object to be cleaned is surrounded and irradiated by the laser irradiation lamp 3 at least twice, thereby ensuring that the laser irradiation lamp 3 completely irradiates the object to be cleaned, so that the cleaning effect of the laser cleaning equipment is better.

[0031] In some embodiments, the laser cleaning equipment of the embodiment of the present invention also includes a first laser 4 and a second laser 5, the laser irradiation lamp 3 includes a first laser irradiation lamp 31 and a second laser irradiation lamp 32, the first laser 4 is connected to the first laser irradiation lamp 31, the first laser 4 is used to generate a first laser to be transmitted to the first laser irradiation lamp 31, so that the first laser irradiation lamp 31 irradiates the object to be cleaned for heating and drying, the second laser 5 is connected to the second laser irradiation lamp 32, the second laser 5 is used to generate a second laser to be transmitted to the second laser irradiation lamp 32, so that the second laser irradiation lamp 32 irradiates the object to be cleaned for disinfection and sterilization.

[0032] like Figure 1 As shown, the laser irradiation lamp 3 includes a first laser irradiation lamp 31 and a second laser irradiation lamp 32 .

[0033] The first laser 4 is preferably but not limited to being connected to the first laser irradiation lamp 31 through the corresponding optical fiber 9. The first laser 4 generates a first laser and transmits it to the first laser irradiation lamp 31 through the corresponding optical fiber 9. The first laser irradiation lamp 31 irradiates the first laser to the object to be cleaned, thereby heating and drying the object to be cleaned through the first laser.

[0034] The second laser 5 is preferably but not limited to being connected to the second laser irradiation lamp 32 through the corresponding optical fiber 9. The second laser 5 generates a second laser and transmits it to the second laser irradiation lamp 32 through the corresponding optical fiber 9. The second laser irradiation lamp 32 irradiates the second laser to the object to be cleaned, thereby disinfecting and sterilizing the object to be cleaned by the second laser.

[0035] When the laser cleaning device is used, the first laser 4, or the second laser 5, or both the first laser 4 and the second laser 5 can be activated according to the type of the object to be cleaned, so as to perform corresponding cleaning treatment on the object to be cleaned.

[0036] The first laser heats and dries the object to be cleaned, which includes two cleaning effects. The first is to evaporate the moisture of impurities such as sludge and rust attached to the surface of the object to be cleaned through the first laser, thereby separating the impurities from the object to be cleaned to achieve laser cleaning. The second is to heat the object to be cleaned through the first laser, evaporate the moisture from the object to be cleaned, and dry and bake the object to be cleaned.

[0037] Therefore, the cleaning meaning of the laser cleaning equipment in the embodiment of the present invention includes laser cleaning, drying and baking, disinfection and sterilization, etc., so the objects to be cleaned by the laser cleaning equipment can be metal paint surfaces, molds, workpieces, food, tobacco leaves, etc.

[0038] When the first laser 4 and the second laser 5 are enabled, it is preferred but not limited to first enabling the first laser 4 to heat and dry the object to be cleaned, and then enabling the second laser 5 to disinfect and sterilize the object to be cleaned.

[0039] In some embodiments, the wavelength of the first laser is 0.808um to 11um, such as 0.808um, 1um, 3um, 5um, 9.5um, 11um, etc., to achieve heating and drying of the items to be cleaned. The wavelength of the second laser is 300nm to 400nm, in other words, the second laser is an ultraviolet laser, such as 300nm, 320nm, 350nm, 375nm, 400nm, etc., to achieve disinfection and sterilization of the items to be cleaned.

[0040] Furthermore, the wavelength of the first laser is 0.808um to 1.5um and 10.6um, for example, 0.808um, 1um, 1.5um, 10.6um, etc., so as to achieve a better heating and drying effect on the items to be cleaned.

[0041] In some embodiments, the laser cleaning device of the embodiment of the present invention further includes a laser beam splitter 6 , there are multiple first laser irradiation lamps 31 , and the laser beam splitter 6 is connected between the multiple first laser irradiation lamps 31 and the first laser 4 .

[0042] like Figure 1 As shown, there are multiple first laser irradiation lamps 31, preferably but not limited to six, and there is preferably but not limited to one second laser irradiation lamp 32.

[0043] The second laser 5 is connected to the second laser irradiation lamp 32 via the first section of optical fiber 9 , so as to transmit the second laser to the second laser irradiation lamp 32 via the first section of optical fiber 9 .

[0044] The first laser 4 is connected to the laser beam splitter 6 through the second section of optical fiber 9, and the laser beam splitter 6 is connected to the six first laser irradiation lamps 31 one-to-one through the six sections of third optical fiber 9. The first laser generated by the first laser 4 is first transmitted to the laser beam splitter 6 and divided into six beams by the laser beam splitter 6, and then the six beams of first laser are transmitted one-to-one to the six first laser irradiation lamps 31 through the six sections of third optical fiber 9.

[0045] The first laser irradiation lamps 31 are arranged in a plurality so that the laser cleaning device has a stronger heating and drying effect on the object to be cleaned. The laser beam splitter 6 is arranged so that the first laser generated by the first laser 4 can be transmitted to the plurality of first laser irradiation lamps 31, so that the structure of the laser cleaning device is simple and the energy consumption is low.

[0046] It can be understood that in some other embodiments, the first laser and the first laser irradiation lamp can be multiple and connected in a one-to-one correspondence.

[0047] It can be understood that, in other embodiments, the second laser irradiation lamp can be provided in plurality, and a corresponding laser beam splitter can be provided between the second laser and the second laser irradiation lamp.

[0048] In some embodiments, the laser cleaning device of the embodiment of the present invention further includes a housing 7 and a driver 8, the cleaning chamber 2 is disposed in the housing 7, and the driver 8 is disposed in the housing 7 and connected to the cleaning chamber 2 to drive the cleaning chamber 2 to rotate relative to the housing 7.

[0049] like Figure 1 As shown, the cleaning chamber 2 is arranged in the outer shell 7, and the driver 8 is arranged at the left end of the outer shell 7 and connected to the left end of the cleaning chamber 2. The driver 8 is preferably but not limited to a rotating motor to drive the cleaning chamber 2 to rotate in the left and right directions relative to the outer shell 7, thereby causing the cleaning chamber 2 to rotate in the left and right directions relative to the object holder 1.

[0050] The cleaning chamber 2 is driven to rotate relative to the object support 1 by the driver 8, so that the structure of the laser cleaning device is relatively simple. At the same time, the object to be cleaned on the object support 1 can be kept stable, thereby preventing the object to be cleaned from being damaged by rotation.

[0051] Furthermore, the housing 7 is provided with a controller 71, which is preferably, but not limited to, provided at one end of the housing 7 for the objects to be cleaned to enter and exit the cleaning chamber 2 (e.g. Figure 1 The right end of the housing 7 shown in the figure), the controller 71 can be a push switch or a touch screen, and the controller 71 is electrically connected to the driver 8 to control the start and stop of the driver 8.

[0052] Furthermore, the driver 8 is connected to a power supply device via a wire 10 .

[0053] In some embodiments, the laser cleaning equipment of the embodiment of the present invention also includes a mounting bracket (not shown in the figure), which is connected to the cleaning chamber 2. The cleaning chamber 2 can drive the mounting bracket to rotate, and the mounting bracket is provided with a first laser 4 and a second laser 5.

[0054] like Figure 1 As shown, the first laser 4, the second laser 5 and the laser beam splitter 6 are all arranged outside the cleaning chamber 2, the first section of optical fiber 9 connecting the second laser 5 and the second laser irradiation lamp 32 is passed through the cleaning chamber 2, and the third section of optical fiber 9 connecting the laser beam splitter 6 and the first laser irradiation lamp 31 is also passed through the cleaning chamber 2.

[0055] A mounting bracket (not shown) is provided at the left end of the cleaning chamber 2. The mounting bracket can be located inside the housing 7 or extend outside the housing 7. The first laser 4, the second laser 5 and the laser beam splitter 6 are all arranged on the mounting bracket.

[0056] When the driver 8 drives the cleaning chamber 2 to rotate, the cleaning chamber 2 drives the mounting bracket to rotate synchronously, so that the first laser 4, the second laser 5, the laser beam splitter 6 and the optical fiber 9 all rotate synchronously, thereby preventing the optical fiber 9 from being entangled and knotted.

[0057] It is understandable that, in other embodiments, the first laser 4 , the second laser 5 and the laser beam splitter 6 may also be disposed on the outer wall of the cleaning chamber 2 , so as to rotate synchronously driven by the cleaning chamber 2 .

[0058] It can be understood that the first section of optical fiber and the third section of optical fiber are not limited to being installed in the cleaning chamber. In other embodiments, the first section of optical fiber and the third section of optical fiber are divided into two parts, one part is installed in the cleaning chamber, and the other part is installed outside the cleaning chamber. A connector is provided on the chamber wall of the cleaning chamber. The connector is connected to a part of the optical fiber located in the cleaning chamber at one end of the inner wall of the cleaning chamber, and is connected to another part of the optical fiber located outside the cleaning chamber at one end of the outer wall of the cleaning chamber.

[0059] In some embodiments, the cleaning chamber 2 is provided with a chamber opening 21 , the object holder 1 is movable relative to the cleaning chamber 2 , and at least a portion of the object holder 1 can enter and exit the cleaning chamber 2 through the chamber opening 21 , thereby allowing the objects to be cleaned to enter and exit the cleaning chamber 2 through the chamber opening 21 .

[0060] like Figure 1 As shown, the cleaning chamber 2 is preferably, but not limited to, at one end of its rotation axis (such as Figure 1 The cleaning chamber 2 shown in the figure has a chamber opening 21 at its right end, and the chamber opening 21 is used for the objects to be cleaned to enter and exit the inner cavity of the cleaning chamber 2. Preferably, the cleaning chamber 2 is a drum with a chamber opening 21 at its right end, and the drum is preferably but not limited to stainless steel.

[0061] The article holder 1 is located on the right side of the cleaning chamber 2 and can move in the left and right direction relative to the cleaning chamber 2 so that at least the left end portion of the article holder 1 can enter and exit the cleaning chamber 2 through the chamber opening 21. The article to be cleaned is arranged on at least the left end portion of the article holder 1 so as to enter and exit the inner cavity of the cleaning chamber 2 through the chamber opening 21 under the drive of the article holder 1.

[0062] It is understandable that the object holder is not limited to being movable relative to the cleaning bin. In other embodiments, the object holder is disposed in the cleaning bin, and an operator takes and places the object to be cleaned from the object holder in the cleaning bin through the bin opening.

[0063] Furthermore, the laser irradiation lamp 3 is in the shape of a bar extending along the rotation axis of the cleaning chamber 2 .

[0064] like Figure 1 As shown, the laser irradiation lamp 3 is in the shape of a bar extending in the left-right direction, and extends from the right end of the cleaning chamber 2 to the left end of the cleaning chamber 2. In the process of the object holder 1 driving the object to be cleaned to move in the left-right direction, the part of the object to be cleaned located in the cleaning chamber 2 is always under the laser irradiation of the laser irradiation lamp 3, and any position along the left-right direction in the cleaning chamber 2 where the object holder 1 moves the object to be cleaned is always under the laser irradiation of the laser irradiation lamp 3, so as to ensure the cleaning effect of the object to be cleaned.

[0065] In some embodiments, the item holder 1 includes a movable frame 11 and a storage platform 12. The movable frame 11 can move closer to and farther from the cleaning chamber 2. The storage platform 12 is arranged on the movable frame 11 so as to enter and exit the cleaning chamber 2 through the chamber opening 21 under the drive of the movable frame 11. The storage platform 12 is used to place items to be cleaned.

[0066] like Figure 1 As shown, the article support 1 includes a moving frame 11 and an article placement platform 12 .

[0067] The moving frame 11 is arranged on the right side of the cleaning chamber 2. The moving frame 11 can be arranged on the linear module to move in the left and right direction under the drive of the linear module. The moving frame 11 can also be arranged on a slide rail or a guide rail, and move in the left and right direction under the drive of a driving device such as a telescopic device, a belt transmission mechanism, a gear rack mechanism, a screw mechanism, etc. under the guidance of the slide rail or the guide rail. The moving frame 11 can also be connected to the housing 7 through a telescopic device such as a telescopic cylinder to move in the left and right direction under the drive of the telescopic device.

[0068] The storage platform 12 is arranged at the left end of the mobile frame 11 and extends to the left from the mobile frame 11. The storage platform 12 is arranged opposite to the warehouse opening 21. The storage platform 12 is used to place the items to be cleaned. The storage platform 12 can be set to be transparent or opaque. The storage platform 12 can be plate-shaped or mesh-shaped.

[0069] The movable frame 11 moves in the left and right direction and drives the storage platform 12 to move in the left and right direction, so that the storage platform 12 can enter and exit the cleaning chamber 2 through the chamber opening 21, so that the objects to be cleaned can enter and exit the cleaning chamber 2, and can stay in the cleaning chamber 2 to be irradiated by the laser irradiation lamp 3 for cleaning.

[0070] Preferably, when the laser cleaning device is cleaning, the movable frame 11 abuts against the right end surface of the housing 7, thereby closing the hatch 21 to prevent the object to be cleaned from accidentally falling out and to prevent the laser from leaking out.

[0071] It is understandable that the structure of the object support is not limited to including a placement platform. In other embodiments, the object support includes a clamping claw, which is used to clamp and release the object to be cleaned.
