Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing blade detection technology, and in particular to a printing blade detection device. Background Technology
[0002] Solder paste printing is a core and crucial preliminary step in surface mount technology. Its core purpose is to accurately and evenly apply solder paste to the pads of the printed circuit board, laying the foundation for reliable solder joints in subsequent component mounting and reflow soldering. During the solder paste printing process, the flatness of the printing squeegee is closely related to the printing effect.
[0003] In the existing technology, when testing the flatness of printing squeegees, it is often necessary to fix the printing squeegee through a rather cumbersome operation. After the subsequent test is completed, it is also necessary to reverse the operation to disassemble the printing squeegee, such as the solution disclosed in the utility model patent with authorization announcement number CN222505278U. The operation is cumbersome and has a significant impact on the testing efficiency.
[0004] Therefore, it is necessary to invent a printing doctor blade detection device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a printing squeegee inspection device that simplifies the inspection process. It can use gravity to position the printing squeegee, eliminating the need for cumbersome operations. This reduces the difficulty of inspection while effectively improving inspection efficiency. It addresses the problem mentioned in the background art that when inspecting the flatness of printing squeegees, it is often necessary to perform cumbersome operations to fix the printing squeegee. After the inspection is completed, it is necessary to reverse the operation to disassemble the printing squeegee, which is cumbersome and has a significant impact on inspection efficiency.
[0006] According to one aspect of this disclosure, the following technical solution is provided: a printing scraper detection device, comprising:
[0007] A scraper support mechanism includes a fixed base plate, an inclined support plate fixedly installed at the top front end of the fixed base plate, a support back plate fixedly installed at the top end of the inclined support plate, a light-transmitting groove opened at the bottom center of the support back plate, and an avoidance groove opened at the top center of the support back plate.
[0008] An illumination mechanism for illuminating a printing squeegee; and
[0009] A light-blocking mechanism is used to block the excess portion of the light-transmitting groove.
[0010] According to at least one embodiment of the printing scraper detection device of the present disclosure, the lighting mechanism includes a U-shaped fixing frame fixedly disposed on the top of the back of the inclined tray, and an illumination lamp is fixedly disposed on the inner side of the U-shaped fixing frame.
[0011] According to at least one embodiment of the printing scraper detection device of the present disclosure, the lighting mechanism further includes a lamp switch, which is fixedly disposed on the top right end of the inclined tray.
[0012] According to at least one embodiment of the printing scraper detection device of this disclosure, the lighting mechanism further includes a rechargeable battery fixedly disposed on the rear side of the top of the fixed base plate, and both the lighting lamp and the rechargeable battery are electrically connected to the lamp switch.
[0013] According to at least one embodiment of the printing squeegee detection device of the present disclosure, the light-shielding mechanism includes a limiting plate fixedly disposed on the right side of the front of the support back plate, the limiting plate blocking the right end of the light-transmitting groove.
[0014] According to at least one embodiment of the printing squeegee detection device of the present disclosure, the light-shielding mechanism further includes a fixing block fixedly disposed on the left side of the front of the support back plate, a sliding shaft is slidably disposed through the left side of the fixing block in the horizontal direction, an L-shaped light-shielding plate is fixedly connected to the right end of the sliding shaft, and a push-pull block is fixedly connected to the left end of the sliding shaft.
[0015] According to at least one embodiment of the printing squeegee detection device of the present disclosure, the back side of the L-shaped light shield is slidably attached to the front side of the support back plate, and the bottom surface of the L-shaped light shield is slidably attached to the top surface of the inclined support plate.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] This invention features a squeegee support mechanism. When testing the flatness of the squeegee's blade edge, the back of the squeegee is placed against the front of the support back plate. The squeegee is then released. Since both the inclined support plate and the back plate are tilted, the squeegee slides down the front of the support back plate under gravity until it rests on the top of the inclined support plate. A light-blocking mechanism then blocks the portion of the light-transmitting groove not obstructed by the squeegee. An illumination mechanism is then activated to illuminate the area behind the light-transmitting groove. By observing whether there is light leakage between the squeegee's blade edge and the top of the inclined support plate, it can be determined whether the squeegee's blade edge is qualified. The tested squeegee is then removed through an clearance groove. Compared to existing technologies, this invention simplifies the testing process, utilizing gravity to position the squeegee without cumbersome operations, reducing testing difficulty and effectively improving testing efficiency.

[0018] The accompanying drawings illustrate exemplary embodiments of the present disclosure and, together with the description thereof, serve to explain the principles of the present disclosure. These drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification.

[0027] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0028] Figure 1This is a schematic diagram of the overall structure of a printing scraper detection device according to one embodiment of the present disclosure.
[0029] Figure 2 This is a schematic diagram of the scraper support mechanism 1 of a printing scraper detection device according to one embodiment of the present disclosure.
[0030] Figure 3 This is a schematic diagram of the lighting mechanism 2 of a printing scraper detection device according to one embodiment of the present disclosure.
[0031] Figure 4 This is a schematic diagram of the light-shielding mechanism 3 of a printing scraper detection device according to one embodiment of the present disclosure.
[0032] like Figures 1-4 As shown, the printing squeegee detection device disclosed herein may include components such as a squeegee support mechanism 1, an illumination mechanism 2, and a light-shielding mechanism 3.
[0033] like Figure 2 As shown in this disclosure, the scraper support mechanism 1 includes a fixed base plate 11, which is made of 6061-T6 aluminum alloy profile. It is lightweight, rust-proof, and easy to process. The fixed base plate 11 has four pre-drilled holes at the top corners. An inclined support plate 12 is fixedly installed at the top front end of the fixed base plate 11. It is made of aluminum alloy plate and the surface is anodized. The anodized layer is wear-resistant, scratch-resistant, oil-resistant, and easy to clean. A support back plate 13 is fixedly installed at the top of the inclined support plate 12. It is also made of aluminum alloy plate and has a smooth surface without burrs. This ensures that the scraper slides down smoothly without jamming when it relies on gravity and does not scratch the back of the scraper. A light-transmitting groove 14 is opened in the middle of the bottom of the support back plate 13. An avoidance groove 15 is opened in the middle of the top of the support back plate 13. The avoidance groove 15 makes it easier for the testing personnel to pick up and put down the printing scraper, reducing the difficulty of picking up and putting down the printing scraper.
[0034] Therefore, to facilitate the flatness test of the printing squeegee's blade position, the back of the printing squeegee is placed against the front of the support back plate 13, and then the printing squeegee is released. Since both the inclined support plate 12 and the support back plate 13 are inclined, the printing squeegee slides down along the front of the support back plate 13 under the action of gravity (when releasing the squeegee, it is necessary to avoid the squeegee being too far from the top of the inclined support plate 12 to avoid excessive impact caused by the squeegee sliding down), until it is pressed against the top of the inclined support plate 12. Then, the light-shielding mechanism 3 blocks the part of the light-transmitting groove 14 that is not blocked by the printing squeegee, and then the lighting mechanism 2 is activated to illuminate from the back of the light-transmitting groove 14. By observing whether there is light leakage between the printing squeegee blade position and the contact surface at the top of the inclined support plate 12, it can be determined whether the current printing squeegee blade position is qualified. Then, the printing squeegee that has been tested is removed through the clearance groove 15. Compared with the existing technology, the testing process is simpler. Gravity can be used to complete the positioning of the printing squeegee, eliminating the need for cumbersome operations, reducing the testing difficulty and effectively improving the testing efficiency.
[0035] like Figure 3 As shown, in a preferred embodiment, the lighting mechanism 2 includes a U-shaped bracket 21 fixedly mounted on the top of the back of the inclined support plate 12. The bracket is made of 304 stainless steel, which is heat-resistant and easy to clean. A lighting lamp 22 is fixedly mounted on the inner side of the U-shaped bracket 21. The lighting mechanism 2 also includes a lamp switch 23, which is fixedly mounted on the top right end of the inclined support plate 12. The lighting mechanism 2 also includes a rechargeable battery fixedly mounted on the rear side of the top of the fixed base plate 11. Both the lighting lamp 22 and the rechargeable battery are electrically connected to the lamp switch 23 (which is conventional technology for those skilled in the art).
[0036] Therefore, after the printing squeegee is positioned and blocked by the portion of the light-transmitting groove 14 outside the light-blocking mechanism 3 that is not blocked by the printing squeegee, the light switch 23 is turned on. After the light switch 23 is turned on, the lighting lamp 22 is powered by the rechargeable battery and emits light. Then, the contact position between the printing squeegee and the top of the inclined support plate 12 is illuminated from the rear side of the light-transmitting groove 14. If there is a gap between the printing squeegee and the top of the inclined support plate 12 due to damage or unevenness of the squeegee, the light will pass through the damaged position and be visible to the naked eye.
[0037] like Figure 4As shown in this disclosure, the light-shielding mechanism 3 includes a limiting plate 31 fixedly installed on the right side of the front of the support back plate 13. The limiting plate 31 is made of 304 stainless steel, which has high hardness and ensures that it will not deform after long-term use. The limiting plate 31 blocks the right end of the light-transmitting groove 14. The light-shielding mechanism 3 also includes a fixing block 32 fixedly installed on the left side of the front of the support back plate 13. A sliding shaft 33 is slidably installed on the left side of the fixing block 32 in the horizontal direction. The sliding shaft 33 is made of chrome-plated carbon steel and is slidably connected to the fixing block 32 through a linear bearing. An L-shaped light-shielding plate 34 is fixedly connected to the right end of the sliding shaft 33. The sliding shaft 34 is made of cold-rolled steel plate. The back of the L-shaped light-shielding plate 34 is slidably attached to the front of the support back plate 13, and the bottom surface of the L-shaped light-shielding plate 34 is slidably attached to the top surface of the inclined support plate 12. A push-pull block 35 is fixedly connected to the left end of the sliding shaft 33. The push-pull block 35 is made of glass fiber reinforced nylon and has anti-slip texture on the surface. It is anti-slip, wear-resistant, comfortable to the touch, and does not feel cold in winter.
[0038] Therefore, after the printing squeegee is placed, the sliding shaft 33 is pushed to the right by the push-pull block 35. At the same time as the sliding shaft 33 moves to the right, the L-shaped light shield 34 moves to the right. When the L-shaped light shield 34 moves to the right, it pushes the printing squeegee until the right end of the printing squeegee is in contact with the left side of the limiting plate 31. During this process, the horizontal part of the L-shaped light shield 34 blocks the light transmission groove 14, thereby preventing light from shining through the part of the light transmission groove 14 that is not blocked by the squeegee and affecting the detection.
[0039] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0040] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
