Description

Technical Field

[0001] The utility model relates to the technical field of chip processing equipment, in particular to a stencil cleaning device and equipment. Background Art

[0002] The printing process is the most important among the three major processes of SMT chip processing. Because about 60% of the SMT process defects are related to this process, and the source of printing defects is the stencil. In addition, the components made by SMT chip processing are developing towards a more precise direction, so the current requirements for stencil cleaning are also getting higher and higher.

[0003] Currently, the general way to clean the stencil is to use the wiping method. Wiping means using a lint-free cloth (or special stencil wiping paper) pre-soaked with a cleaning agent to wipe the stencil to remove the cured solder paste or adhesive, but this method is too dependent on manual labor and is rather troublesome. Content of the Utility Model

[0004] The purpose of the utility model is to provide a stencil cleaning device aiming at the technical problems existing in the background art.

[0024] The following will make a detailed description of the specific embodiments of the present utility model with reference to the drawings.

[0025] As Figures 1 - 4As shown in the figure, a stencil cleaning device is proposed in the first aspect of the present utility model, which includes a cleaning mechanism 100 and a detection mechanism 200 respectively placed at the side of the stencil. The cleaning mechanism 100 is used to clean the stencil, and the detection mechanism 200 is used to detect the cleanliness of the stencil. The cleaning mechanism 100 includes a driving group, a mounting seat 102, a cleaner 103, a liquid supply device 104 and a blower 105. The mounting seat 102 is drivingly connected to the driving group. Driven by the driving group, the mounting seat 102 moves to any position of the stencil. The cleaner 103 is installed on the mounting seat 102 and is used to brush the stencil. The liquid supply device 104 is installed on the mounting seat 102 and is used to spray cleaning liquid and cooperate with the cleaner 103 to brush the stencil. The blower 105 is installed on the mounting seat 102 and is placed above the cleaner 103 and the liquid supply device 104, and the blower 105 is used to dry the stencil.

[0026] Specifically, in actual use, the stencil is transported to the stencil cleaning device by an external transportation device. The external transportation device includes transportation and stopping functions. When transporting the stencil to the stencil cleaning device, the transportation is stopped, so that the stencil stays in the stencil cleaning device until the cleaning work is completed. The cleaning mechanism 100 will first perform the first cleaning on the stencil. The driving group drives the cleaner 103 and the liquid supply device 104 to brush at any position of the stencil. After the brushing is performed, the driving group drives the blower 105 to detect the stencil. If no other dirt or impurities are detected, the stencil is dried and the cleaning work of the stencil is completed. If excess dirt or impurities are still detected, the driving group is activated again to perform the above cleaning work until no dirt or impurities are detected.

[0027] Furthermore, the driving group includes a guide rail 1011 and a first driving member 1012 installed on the guide rail 1011. The laying direction of the guide rail 1011 is the same as the length or width direction of the stencil. The mounting seat 102 is slidably installed on the guide rail 1011 and is drivingly connected to the first driving member 1012.

[0028] The mounting seat 102 includes a sliding plate 1021 and a mounting frame 1022. The sliding plate 1021 is slidably installed on the guide rail 1011 and is drivingly connected to the first driving member 1012. The mounting frame 1022 is slidably installed on the sliding plate 1021. The driving group further includes a second driving member 1013. The second driving member 1013 is installed on the mounting frame 1022 and is drivingly connected to the mounting frame 1022 to drive the mounting frame 1022 to approach or move away from the stencil. The cleaner 103, the liquid supply device 104 and the blower 105 are all installed on the mounting frame 1022.

[0029] Specifically, the first driving member 1012 is a lead screw motor, and the second driving member 1013 is a cylinder structure. The lead screw motor drives the slide plate 1021 to move in the length or width direction of the stencil. It should be noted that setting the direction to be the same as the length or width direction of the stencil is determined according to production requirements. Of course, this setting also needs to be orthogonal to the transportation direction of the external transportation device to cooperate with the external transportation device to clean any position of the stencil. The cleaner 103, the liquid supply device 104, and the air blower 105 are all installed on the mounting frame 1022. So that during the cleaning process, the cleaner 103, the liquid supply device 104, and the air blower 105 are all driven to approach the stencil to ensure thorough cleaning. After the cleaning is completed, the cleaner 103, the liquid supply device 104, and the air blower 105 are all driven away from the stencil to facilitate the transportation of the stencil to other devices and the transportation of the next stencil into the machine.

[0030] Further, the cleaner 103 includes a third driving member 1031 and a brush 1032. The brush 1032 is installed at the output end of the third driving member 1031.

[0031] Specifically, the third driving member 1031 is a rotary motor to drive the brush 1032 to rotate, so as to fully clean the stencil.

[0032] Further, the air blower 105 is a air knife structure.

[0033] Further, there are two sets of cleaning mechanisms 100. The two sets of cleaning mechanisms 100 are symmetrically arranged on both sides of the stencil respectively to comprehensively clean the stencil and improve the cleaning effect.

[0034] Specifically, the cleaning mechanism 100 further includes a waterproof cover, which shields the driving equipment related to the cleaning mechanism 100 and the surrounding of the cleaning mechanism 100 to prevent water stains from splashing onto important equipment during the brushing process and affecting the service life of the equipment. The waterproof cover arranged around the cleaning mechanism 100 adopts a bellows cover.

[0035] Further, the detection mechanism 200 includes a three-axis drive group 201 and a visual recognition device 202. The visual recognition device 202 is drivingly connected to the three-axis drive group 201. Driven by the three-axis drive group 201, the visual recognition device 202 moves to any position of the stencil.

[0036] Further, the detection mechanism 200 further includes a tensiometer 203. The tensiometer 203 is drivingly connected to the three-axis drive group 201.

[0037] The second aspect of the present utility model provides a device, which is characterized in that it includes the stencil cleaning device according to any one of the above solutions.

[0038] The above is a stencil cleaning device or multiple embodiments provided in combination with specific contents, and it is not considered that the specific implementation of the present utility model is only limited to these descriptions. Any method, structure, etc. that is similar or identical to the present utility model, or any technical deduction or substitution made under the premise of the concept of the present utility model, should be regarded as within the protection scope of the present utility model.
