For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0021] The following will describe in detail the specific embodiments of the present utility model with reference to the drawings.

[0022] As Figures 1-4As shown in the figure, a fixed-point cleaning mechanism is proposed in the first aspect of the present utility model, which is used to locate and clean the dirt on the stencil. The fixed-point cleaning mechanism includes a cleaning part 100 and a driving part 200. The cleaning part 100 is connected to the driving part 200. Driven by the driving part 200, the cleaning part 100 moves in the three-dimensional space above the stencil. The cleaning part 100 includes a visual recognition device 101, a locator 102 and a cleaning member 103 that are electrically connected to each other. The visual recognition device 101 is used to recognize the dirt on the stencil. The locator 102 is electrically connected to the driving part 200 and is used to record the position coordinates of the dirt. Among them, according to the position coordinates of the dirt, the driving part 200 drives the cleaning member 103 to the position of the dirt to clean the dirt. After the cleaning is completed, the visual recognition device 101 is used to recognize the dirt at this position to confirm the cleanliness.

[0023] Specifically, the cleaning part 100 is placed above the stencil and can be arbitrarily moved in the three-dimensional space above the stencil through the driving part 200 to detect and clean the dirt at any position on the stencil. In this embodiment, the driving part 200 adopts a three-axis driving mechanism, specifically the three-axis three-dimensional driving mechanism described below. Of course, the driving part 200 can also adopt driving devices such as a manipulator or a robotic arm, which can be assembled according to actual needs. The former has a low development cost and can quickly and accurately obtain the position of the dirt on the stencil and clean it, while the latter can be more precise.

[0024] Furthermore, the driving part 200 includes a Z-axis driving component 201, an X-axis driving component 202 and two Y-axis driving components 203 that are sequentially drivingly connected. The Y-axis driving component 203 includes a first guide rail 2031 and a first driving member 2032. The X-axis driving component 202 includes a cross beam 2021 and a second driving member 2022 and two second guide rails 2023 that are both installed on the cross beam 2021. The two ends of the cross beam 2021 are respectively slidably installed on the two first guide rails 2031 and are respectively drivingly connected to the two first driving members 2032. The Z-axis driving component 201 includes a first mounting seat 2011 and a second mounting seat 2012 and a third driving member 2013 that are both installed on the first mounting seat 2011. The first mounting seat 2011 is slidably installed on the two second guide rails 2023 and is drivingly connected to the second driving member 2022. The second mounting seat 2012 is drivingly connected to the third driving member 2013. The locator 102 and the cleaning member 103 are both installed on the first mounting seat 2011, and the visual recognition device 101 is installed on the second mounting seat 2012.

[0025] Specifically, through the cooperation of the X-axis driving component 202 and two groups of Y-axis driving components 203, the locator 102 and the cleaning member 103 can be moved to any position on the XY plane, that is, to any position on the stencil surface for positioning and cleaning. The vision recognizer 101 is independently controlled by the Z-axis driving component 201 to move in the Z-axis direction. When the vision recognizer 101 detects an unclear area on the stencil, it can be further focused on this position and perform secondary detailed detection under the drive of the Z-axis driving component 201. Of course, a multi-step stencil detection form can also be adopted. For example, in the first detection, the vision recognizer 101 is at a relatively high detection height. After traversing the stencil and cleaning, the Z-axis driving component 201 drives the vision recognizer 101 to descend by a certain height and perform the second detection. If there are still fine dirt, clean it again. After the secondary cleaning, the Z-axis driving component 201 drives the vision recognizer 101 to descend by a certain height again, and so on, until the dirt on the stencil cannot be detected and processed by the vision recognizer 101, then the detection and cleaning work can be completed.

[0026] Further, an installation plate 2011a is provided on the first mounting seat 2011. Two fixing holes 2011b are provided on the installation plate 2011a. The cleaning part 100 further includes an adjusting block 104. Two adjusting slots 1041 and two fasteners 1042 corresponding to the two fixing holes 2011b are provided on the adjusting block 104. The adjusting block 104 is mounted on the installation plate 2011a by respectively assembling the fasteners 1042 into the adjusting slots and the fixing holes 2011b. The cleaning member 103 is mounted on the installation plate 2011a. Among them, by passing the fasteners 1042 into different positions of the adjusting slots to adjust the assembling angle of the adjusting block 104, the cleaning position and cleaning angle of the cleaning member 103 are further adjusted. The cleaning member 103 includes an air jet gun.

[0027] Further, the cleaning part 100 further includes a third mounting seat 105 and a tensiometer 106 mounted on the third mounting seat 105. The tensiometer 106 is fixedly connected to the second mounting seat 2012 through the third mounting seat 105. The tensiometer 106 is used to detect the surface tension of the stencil.

[0028] Specifically, there is a certain force on the stencil during the cleaning process. Therefore, it is necessary to use the tensiometer 106 to check the surface tension of the stencil to determine whether the stencil can be used normally.

[0029] Further, the first driving member 2032, the second driving member 2022, and the third driving member 2013 are all screw drive motors.

[0030] In the second aspect of the present utility model, an equipment is provided, which is characterized in that it includes the fixed-point cleaning mechanism according to any one of the above solutions.

[0031] The above is a fixed-point cleaning mechanism or multiple implementation manners provided in combination with specific contents, and it is not determined that the specific implementation of the present utility model is only limited to these descriptions. All those that are similar or identical to the method and structure of the present utility model, or those that make several technical deductions or substitutions under the premise of the concept of the present utility model, shall be regarded as the protection scope of the present utility model.
