Description

Technical Field

[0001] This utility model relates to the field of metal workpiece inspection technology, and in particular to a rapid contact device for two-dimensional microscopes. Background Technology

[0002] Two-dimensional microscopes are primarily used to observe and study tiny two-dimensional samples or surfaces. They provide high-resolution images, enabling inspectors to better study the surface morphology, structure, and microscopic properties of materials. Currently, inspectors often use two-dimensional microscopes to check for burrs on the edges and corners of micro-contact workpieces.

[0003] Currently, inspectors often use tweezers to hold the micro-contact workpieces and adjust their position within the field of view of a two-dimensional microscope. This requires inspectors to control the clamping force on the micro-contact workpieces. Otherwise, it is easy for the micro-contact workpieces to be deformed and damaged due to excessive clamping force, or for the micro-contact workpieces to slip out of the tweezers due to insufficient clamping force, which increases the difficulty for inspectors to inspect the micro-contact workpieces.

[0004] Therefore, a rapid contact detection device using a two-dimensional microscope is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rapid contact detection device using a two-dimensional microscope to solve the above-mentioned problems, thereby improving the difficulty of fixing and observing existing micro-contact workpieces under a two-dimensional microscope, which increases the difficulty of detection.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a rapid detection contact device for a two-dimensional microscope, comprising: a base plate; an unwinding mechanism and a winding mechanism, wherein the unwinding mechanism and the winding mechanism are symmetrically distributed at both ends of the base plate; and a transparent nano-adhesive tape roll, wherein the transparent nano-adhesive tape roll is sleeved on the surface of the unwinding mechanism, and one end of the transparent nano-adhesive tape roll extends beyond the base plate and is wound around the surface of the winding mechanism.

[0007] Preferably, the unwinding mechanism and the winding mechanism have the same structure. The unwinding mechanism includes a circular frame fixedly connected to one end of the base plate. A rotating shaft is rotatably connected to the inner side of the circular frame. An installation cylinder is inserted into the surface of the rotating shaft. One end of the transparent nano tape roll is wound around the surface of the installation cylinder.

[0008] Preferably, a rectangular frame is fixedly connected to the top of the base plate, and guide openings are provided at both ends of the rectangular frame. One end of the transparent nano tape roll passes through one of the guide openings and extends to the outside of the other guide opening. The surfaces of the rectangular frame and the guide openings are coated with Teflon coating.

[0009] Preferably, a center line is provided at the top of the base plate, and the center line, the center plate, and the center point of the rectangular frame all coincide.

[0010] Preferably, a foam pad is fixedly connected to the bottom of the base plate, and the cross-sectional shape of the upper surface of the foam pad is C-shaped.

[0011] Preferably, the bottom of the foam pad is adhered with nano double-sided adhesive.

[0012] Preferably, a lever is fixedly connected to the surface of the base plate, and the corners of the lever are rounded.

[0013] Preferably, the surface of the rotating shaft is provided with a threaded groove, and a nut that contacts the mounting cylinder is threadedly connected to the surface of the threaded groove.

[0014] Preferably, a ratchet is fixedly connected to the surface of the rotating shaft, and a pawl that meshes with the ratchet is rotatably connected inside the circular frame.

[0015] The beneficial effects of this utility model are:

[0016] 1. The design of transporting micro-contact workpieces through transparent nano-adhesive tape rolls eliminates the need for inspectors to control the fixing force of the micro-contact workpieces under a two-dimensional microscope, effectively reducing the probability of deformation and damage to the micro-contact workpieces due to external forces. At the same time, inspectors can place multiple micro-contact workpieces sequentially on the adhesive surface of the transparent nano-adhesive tape roll, and then place them sequentially above the center line, enabling inspectors to quickly perform batch inspections and improve inspection efficiency.

[0017] 2. The inspector can adjust the lever according to the requirements, so that the base plate tilts the transparent nano tape roll simultaneously through the unwinding and rewinding mechanisms. This causes the transparent nano tape roll to tilt the micro contact workpiece and change its orientation towards the local area of ​​the two-dimensional microscope, thereby expanding the inspector's inspection range of the micro contact workpiece.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-4 As shown, the rapid contact detection device for a two-dimensional microscope includes: a base plate 100; an unwinding mechanism 200 and a winding mechanism 300, both of which are symmetrically distributed at both ends of the base plate 100; and a transparent nano-adhesive tape roll 400, which is sleeved on the surface of the unwinding mechanism 200, with one end of the transparent nano-adhesive tape roll 400 extending over the base plate 100 and wound around the surface of the winding mechanism 300.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, a rectangular frame 500 is fixedly connected to the top of the base plate 100. Guide openings 510 are provided at both ends of the rectangular frame 500. One end of the transparent nano-adhesive tape roll 400 passes through one of the guide openings 510 and extends to the outside of the other guide opening 510. The surfaces of the rectangular frame 500 and the guide openings 510 are coated with Teflon coating. The rectangular frame 500 can help the inspector adjust the observation range of the observation lens in the two-dimensional microscope to the corresponding range, so as to reduce the burden of subsequent adjustment by the inspector. At the same time, the Teflon coating design can also reduce the adhesion of the transparent nano-adhesive tape roll 400 to the guide opening 510 or the rectangular frame 500, so as to facilitate cleaning and maintenance by the inspector. A center line 110 is provided on the top of the base plate 100. The center line 110, the center point of the base plate 100 and the rectangular frame 500 all coincide. The center line 110 can help the inspector quickly adjust the micro-contact workpiece to be directly below the observation lens in the two-dimensional microscope.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, a foam pad 600 is fixedly connected to the bottom of the base plate 100. The cross-sectional shape of the upper surface of the foam pad 600 is C-shaped. Nano double-sided adhesive 700 is bonded to the bottom of the foam pad 600. This allows the testing personnel to adjust the tilt angle of the base plate 100 as needed, so that it can test different surfaces of the micro-contact workpiece. A lever 800 is fixedly connected to the surface of the base plate 100. The corners of the lever 800 are rounded, which can reduce the burden on the testing personnel to adjust the angle of the base plate 100.

[0027] Before using the device, first align the center line 110 with the axis of the two-dimensional microscope carrier plate, and then use nano double-sided tape 700 to bond the foam pad 600 to the two-dimensional microscope carrier plate, thus completing the pre-fixation work of the two-dimensional microscope rapid detection contact device.

[0028] When the inspector needs to observe other angles of the micro-contact workpiece, the inspector only needs to press down or lift up the lever 800 accordingly. The lever 800 causes the base plate 100 to tilt and squeeze the foam pad 600. At the same time, the base plate 100 tilts the transparent nano-adhesive tape roll 400 through the unwinding mechanism 200 and the winding mechanism 300. This causes the transparent nano-adhesive tape roll 400 to tilt the micro-contact workpiece and change its orientation towards the local area of ​​the two-dimensional microscope, thereby expanding the inspector's inspection range of the micro-contact workpiece.

[0029] like Figure 4 As shown, the unwinding mechanism 200 and the winding mechanism 300 have the same structure. The unwinding mechanism 200 includes a circular frame 210 fixedly connected to one end of the base plate 100. A rotating shaft 220 is rotatably connected to the inner side of the circular frame 210. An mounting cylinder 230 is inserted into the surface of the rotating shaft 220. The cross-sectional shape of the connection between the mounting cylinder 230 and the rotating shaft 220 is an H-shape that matches each other. One end of the transparent nano-adhesive tape roll 400 is wound around the surface of the mounting cylinder 230. A threaded groove 221 is formed on the surface of the rotating shaft 220. A nut 2 that contacts the mounting cylinder 230 is threadedly connected to the surface of the threaded groove 221. 40, which facilitates the installation or removal of the transparent nano tape roll 400 by the inspection personnel, thereby reducing the overall usage burden of the device; a ratchet 250 is fixedly connected to the surface of the rotating shaft 220, and a pawl 260 that meshes with the ratchet 250 is rotatably connected inside the circular frame 210. The pawl 260 can indirectly prevent the transparent nano tape roll 400 from retracting through the ratchet 250, thereby avoiding the probability of the transparent nano tape roll 400 becoming loose and wrinkled during the process of the inspection personnel removing the workpiece or pulling the transparent nano tape roll 400, thus improving the tightness of the transparent nano tape roll 400 during use;

[0030] When the inspector needs to release the transparent nano tape roll 400, the inspector only needs to rotate the rotating shaft 220 accordingly. The rotating shaft 220 drives the mounting cylinder 230 to rotate, and the mounting cylinder 230 drives the transparent nano tape roll 400 to rotate and release. Since the unwinding mechanism 200 and the winding mechanism 300 have the same structure, the winding of the transparent nano tape roll 400 is also the same as the above operation.

[0031] In use, the inspector simply places the micro-contact workpiece on the adhesive surface of the transparent nano-adhesive tape roll 400, and then manually drives the winding mechanism 300 to wind up the transparent nano-adhesive tape roll 400. The transparent nano-adhesive tape roll 400 carries the micro-contact workpiece through the guide opening 510 and into the inner side of the rectangular frame 500 until the micro-contact workpiece is moved directly above the center line 110. At this point, the inspector can observe whether there are any burrs on the edges of the micro-contact workpiece under magnification using a two-dimensional microscope. This eliminates the need for the inspector to control the fixing force of the micro-contact workpiece under the two-dimensional microscope, effectively reducing the probability of deformation and damage to the micro-contact workpiece due to external force. At the same time, the inspector can place multiple micro-contact workpieces sequentially on the adhesive surface of the transparent nano-adhesive tape roll 400 and then sequentially above the center line 110, enabling the inspector to quickly perform batch inspections and improve inspection efficiency.

[0032] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
