Description

Technical Field

[0001] The invention relates to the field of ink dispensing processing, and in particular to an ink splash prevention device for an ink dispensing machine. Background Art

[0002] During the quality inspection of wafers, wafers need to be marked. Wafer ink dotting machines can mark specific locations on wafers. By using ink dotting machines, dots can be placed on the wafer to mark the locations of defective or abnormal die. These marks are helpful for subsequent inspection and processing. At present, the bottom of the ink dot machine directly contacts the wafer surface, and the ink dot port is in the open space above the wafer, with a large contact area. During the ink dot process, when ink splashes from the ink dot port, it is easy to cause ink contamination to other locations. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to provide an ink splash prevention device for an ink dispenser.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: an ink splash prevention device for an ink dispenser, comprising an ink dispenser, and also comprising: an ink dispenser cavity, wherein the ink dispenser cavity is arranged on the top of the ink dispenser; an annular lifting platform, wherein the annular lifting platform is arranged inside the ink dispenser cavity; a shielding plate, wherein the shielding plate is a sub-grid plate and is made of a transparent material, wherein the shielding plate cover is arranged on the top surface of the annular lifting platform, and a clearance opening for making way for the ink dispenser is opened on the surface; a plurality of mounting ports, wherein a plurality of the mounting ports are arranged in an annular array on the surface of the annular lifting platform; a plurality of receiving frames, wherein the plurality of receiving frames are respectively arranged inside the plurality of mounting ports, wherein the receiving frames comprise a receiving plate and a positioning clamp; a linkage component, wherein the linkage component is used for the linkage receiving plate to extend out and be in a receiving state during the process of the annular lifting platform extending out of the ink dispenser cavity, and the linkage positioning clamp moves to make way for the receiving plate to make way, and during the process of the annular lifting platform descending into the ink dispenser cavity, before the linkage receiving plate is retracted into the mounting port, the linkage positioning clamp moves close to the shielding plate to clamp and position the edge of the shielding plate.

[0005] Specifically, an electric cylinder is fixedly installed between the bottom of the annular lifting platform and the inner bottom surface of the ink dot chamber, and an annular baffle is fixedly connected to the top of the annular lifting platform to cover the installation opening.

[0006] It should be understood that before ink dotting, the workpiece to be dotted is placed in the ink dotting chamber, and a shielding plate is placed in the ink dotting chamber, so that the ink dotting port of the ink dotting machine can only partially dot the ink on the workpiece to be dotted in the ink dotting chamber blocked by the shielding plate through the yielding port, so that during the entire ink dotting process, only the operation window is left, and the area of ​​the ink dotting machine directly contacting the wafer surface is greatly reduced, so as to prevent the ink dot port from splashing ink and causing ink dot contamination to other positions, thereby helping to improve the problem of low-quality ink contaminating the workpiece to be dotted; It should be further explained that, in the process of installing the shielding plate, the annular lifting platform is first lifted out of the ink-dotting chamber, and the receiving plate and the positioning clamp are moved out to provide a spacious space for receiving the shielding plate. In the process of the annular lifting platform extending out of the ink-dotting chamber, the linkage component will link the receiving plate to extend and be in a receiving state, the linkage positioning clamp moves to make room for the receiving plate, the shielding plate is set on multiple receiving plates in a receiving state, and then the annular lifting platform is lowered into the ink-dotting chamber. In the process of lowering the annular lifting platform into the ink-dotting chamber, before the linkage component links the receiving plate to retract into the installation opening, the linkage positioning clamp extends out of the installation opening to clamp and position the edge of the shielding plate, so as to achieve clamping before the receiving plate is detached from the bottom end of the shielding plate, so as to avoid the cover plate from falling directly and causing damage to the shielding plate. During the installation of the baffle plate, the baffle plate is actively installed into the narrow ink-dispensing chamber space, and the installed baffle plate is automatically clamped and positioned to prevent the baffle plate from shifting during use and causing the yielding port to collide with the ink-dispensing machine.

[0007] As a further optimized technical solution of the present invention, a docking platform is fixedly connected to the top of the receiving plate located at the clearance opening, and the docking platform is adapted to the clearance opening.

[0008] It should be understood that when the receiving plate is in the receiving state, during the process of placing the baffle plate on multiple receiving plates, the making way opening will be aligned with the docking table, and the docking table will limit the making way opening so that the making way opening is aligned with the position of the ink dotting machine installed in the ink dotting chamber, so as to avoid collision with the ink dotting machine when the baffle plate is moved into the ink dotting chamber, thereby affecting the normal installation of the baffle plate.

[0009] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, during the whole process of ink dotting, the shielding plate is used to block the ink, leaving only the opening as an operation window, thereby greatly reducing the area of ​​the ink dotting machine directly contacting the wafer surface, preventing the ink dot port from splashing ink and causing ink dot contamination to other positions, thereby facilitating the problem of low-quality ink dots causing contamination to the ink dotted parts; By setting up a receiving frame and a circular lifting platform, during the installation of the baffle plate, the baffle plate can be actively installed into the narrow ink-dispensing chamber space, and the installed baffle plate can be automatically clamped and positioned to avoid the baffle plate from shifting during use and causing the yielding port to collide with the ink-dispensing machine.

[0010] The present invention, by arranging a docking platform, will always limit the position of the shielding plate which is still on the receiving plate, and keep the clearance opening facing the ink dispenser until the positioning clamp has completed the clamping positioning, and the receiving plate drives the docking platform to separate from the shielding plate, so that the shielding plate is always kept in an ideal installation state during the entire process of installing the shielding plate, avoiding collision with the ink dispenser.

[0027] It should be understood that when the receiving plate 7 is in the receiving state, during the process of placing the baffle plate 4 on multiple receiving plates 7, the clearance opening 5 will be aligned with the docking platform 9, and the docking platform 9 will limit the clearance opening 5 so that the clearance opening 5 is aligned with the position of the ink dotting machine installed in the ink dotting chamber 101, so as to avoid collision with the ink dotting machine when the baffle plate 4 is moved into the ink dotting chamber 101, thereby affecting the normal installation of the baffle plate 4.

[0028] like Figure 2 , Figure 3 , Figure 7 and Fig.11As shown, as an embodiment of the present invention, it also includes a mounting table 10, the top surface of the mounting table 10 is rotatably connected to a mounting disk 11, the top of the mounting table 10 is fixedly connected to a mounting plate 12 corresponding to the position of the yield opening 5, the mounting plate 12 is used to install the ink dispenser, the mounting disk 11 is used to install the parts to be inked, and a motor 13 is fixedly installed between the mounting disk 11 and the mounting table 10.

[0029] Specifically, a mounting cavity is provided at the top of the mounting platform 10, a mounting plate 11 is rotatably connected to the top of the mounting cavity, a motor 13 is fixedly mounted on the bottom surface of the mounting cavity, and an output end is fixedly connected to the mounting plate 11; It should be understood that by setting up the mounting table 10, the ink dispenser and the workpiece to be ink-dotted are supported.

Under the guidance of the first ventilation pipe 24 and the second ventilation pipe 25, the first airbag 804 and the second airbag 805 are inflated, thereby achieving further clamping and positioning of the edge of the baffle plate 4 between the upper clamp plate 802 and the lower clamp plate 803.

[0036] like Fig.10 As shown, as a preferred embodiment of the present invention, a first support spring 26 is fixedly connected between the piston plate 21 and the inflation chamber 20. It should be understood that by providing the first support spring 26, when the positioning clamp 8 leaves the shielding plate 4, the piston plate 21 is supported and reset, and then the first airbag 804 and the second airbag 805 are further restored to their original state, maintaining the initial clamping space, so as to prepare for the next clamping of the shielding plate 4.
