[0033] The carrier 12 is disposed on the machine 11, and a to-be-cleaned object unit 9 is placed on the carrier 12. The feeding system 2 includes an X-axis feeding unit 21, a Y-axis feeding unit 22, and a Z-axis feeding unit 23. The X-axis feeding unit 21 is arranged along an X-axis, the Y-axis feeding unit 22 is arranged along a Y-axis, and the Z-axis feeding unit 23 is arranged along a Z-axis. The Y-axis feeding unit 22 is assembled with the machine 11, the X-axis feeding unit 21 is assembled with the Y-axis feeding unit 22, and the Z-axis feeding unit 23 is assembled with the X-axis feeding unit 21.

Each of the first limit assemblies 3 includes a first base 31 and a first stopping unit 32. The first stopping unit 32 is arranged on the first base 31. The first base 31 can move relative to the carrier 12 along the X-axis in accordance with the size of the object unit 9 to be cleaned in the X-axis direction, so that the first stopping unit 32 can stop the object unit 9 to be cleaned in the Y-axis direction to ensure that the object unit 9 to be cleaned cannot separate from the carrier 12 along the Y-axis during the cleaning process; wherein, the two first bases 31 located on both sides of the carrier 12 also have the function of restraining and limiting the object unit 9 to be cleaned.

[0035] Each of the first limiting components 3 further includes at least one abutting unit 33, and the at least one abutting unit 33 is arranged on the first base 31 to abut the object unit 9 to be cleaned in the X-axis direction, and then the at least one abutting unit 33 of the two first limiting components 3 can be used to clamp and position the object unit 9 to be cleaned together. In this way, in conjunction with the first stopping unit 32, the object unit 9 to be cleaned will be restricted in both the X-axis and the Y-axis and cannot be moved or rotated arbitrarily, which can have an excellent positioning effect and improve the cleaning stability.

[0036] In this embodiment, the first stop unit 32 is rotatably disposed on the first base 31, and the first stop unit 32 is operable to selectively stop or not stop the object unit 9 to be cleaned, and the user can quickly operate by rotating. In addition, the number of the at least one abutting unit 33 is plural, and the plural abutting units 33 are arranged at intervals along the Y axis to uniformly provide support force to the object unit 9 to be cleaned. In addition, each of the abutting units 33 is preferably movable along the X axis, and the force of each of the abutting units 33 pressing against the object unit 9 to be cleaned can be further adjusted as needed.

[0037] Preferably, each of the first limiting components 3 further includes a conveying unit 34, which is disposed on the first base 31 and extends along the Y-axis. The conveying unit 34 can be used for the object unit 9 to be cleaned to abut against, and then the conveying unit 34 drives the object unit 9 to be cleaned to abut against and move along the Y-axis, thereby quickly adjusting the position of the object unit 9 to be cleaned on the Y-axis, which saves time and effort.

[0038] Another preferred embodiment is that the conveying unit 34 can be raised and lowered along the Z-axis on the first base 31. When movement is required, the conveying unit 34 will rise along the Z-axis to lift the object unit 9 to be cleaned away from the carrier 12 to reduce friction and facilitate movement. Conversely, when cleaning is performed, the conveying unit 34 will descend along the Z-axis to press the object unit 9 to be cleaned against the carrier 12 to ensure that the object unit 9 to be cleaned does not move arbitrarily and the weight of the object unit 9 to be cleaned does not press against the conveying unit 34 for a long time, thereby maintaining the structure of the conveying unit 34 less prone to deformation.

[0039] Preferably, the laser cleaning device further includes two second limit assemblies 4, each of the second limit assemblies 4 includes a second base 41 and a second stop unit 42, the second base 41 can be movably disposed on the machine 11 along the Y-axis, the second stop unit 42 can be rotatably disposed on the second base 41 and can selectively abut against the object unit 9 to be cleaned in the Y-axis direction, and thus the second stop unit 42 and the first stop unit 32 can accurately match the size of the object unit 9 to be cleaned in the Y-axis direction for clamping.

[0040] The laser cleaning assembly 5 is disposed on the Z-axis feeding unit 23, and the laser cleaning assembly 5 is used to emit a laser beam to clean the object unit 9 to remove the residue or dust adhering to the object unit 9. The object unit 9 to be cleaned includes, for example but not limited to, a substrate 91 and a metal needle 92, the metal needle 92 is inserted into the substrate 91, the plurality of abutting units 33 of the two first stopper assemblies 3 clamp the substrate 91 in the X-axis direction, the second stopper unit 42 and the first stopper unit 32 clamp the substrate 91 in the Y-axis direction, and the laser cleaning assembly 5 can be moved arbitrarily through the feeding system 2 to clean the metal needle 92.

[0041] The laser cleaning assembly 5 includes a base 51, a laser output head 52 and a scanning head 53. The base 51 is arranged on the Z-axis feeding unit 23. The laser output head 52 and the scanning head 53 are arranged on the base 51. The scanning head 53 is used to scan the object unit 9 to be cleaned to define a working range, so that the laser beam output by the laser output head 52 can only move within the working range to ensure that the laser beam will not damage the area outside the metal needle-shaped object 92 during the cleaning process.

[0042] Preferably, the laser cleaning assembly 5 further includes a height measuring device 54 disposed on the Z-axis feeding unit 23, and the height measuring device 54 is used to control the distance between the laser output head 52 and the object unit 9 to be cleaned in the Z-axis direction to ensure that the laser is focused on the residue or dirt of the metal needle-shaped object 92 without damaging the metal needle-shaped object 92 and achieving an effective cleaning effect.

[0043] Another preferred embodiment is that the laser cleaning assembly 5 further includes at least one image capture unit 55 disposed on the base 51. The at least one image capture unit 55 is used to capture the image of the object to be cleaned unit 9. For example, the at least one image capture unit 55 is two in number, one is a low-magnification image capture unit for capturing the image of the metal needle-shaped object 92 before cleaning, and the other is a high-magnification image capture unit for capturing the image of the metal needle-shaped object 92 after cleaning, so as to accurately understand the degree of cleaning. In addition, the at least one image capture unit 55 can also have the effect of height detection with the aid of software integration, and can have the effect of double confirmation of height distance in conjunction with the height measuring device 54.

[0044] In another preferred embodiment, the laser cleaning component 5 further comprises a dust collecting system 71 , which is disposed on the machine platform 11 to absorb dirt by negative pressure to keep the laser cleaning device clean.

[0045] In the present embodiment, the laser cleaning assembly 5 further includes a laser emitting device 58, which is disposed on the X-axis feeding unit 21 and connected to the laser output head 52. The laser emitting device 58 includes a blocking member 56 and an optical path mechanism 57.

When the blocking member 56 is located at the open position, the blocking member 56 is not located on the path of the laser light beam emitted by the laser light signal source, and the laser light beam can be emitted through the laser output head 52.

[0046] In detail, when the laser cleaning device is in operation, the blocking member 56 cooperates with the emergency stop button to switch the blocking member 56 to the blocking position to ensure that in an emergency situation, the blocking member 56 can quickly prevent the laser beam from continuing to be emitted, and can reduce the subsequent continuous damage caused by the laser beam. When the laser cleaning device is not in operation, the blocking member 56 is normally in the blocking position, and when the laser cleaning device is started, the blocking member 56 switches to the open position. It should be supplemented that the blocking member 56 can be switched between the blocking position and the open position by moving and rotating at least one of them, and is not limited to its activity mode.
