Description

A contact angle measuring device for a conductor Technical Field

[0001] This invention relates to the field of contact angle measurement technology, and in particular to a contact angle measuring device for a conductor. Background Technology

[0002] Most portable contact angle measuring instruments on the market have a flat bottom; the base and housing are not fixed, and the inside of the housing is hollow. During measurement, water is dripped onto the sample surface through a syringe, and the LED light inside the contact angle measuring instrument illuminates the space inside the housing, making it easy to observe the contact angle of the water droplet on the sample surface. By plugging the USB interface of the portable contact angle measuring instrument into a computer, the contact angle can be directly fitted in the software on the computer.

[0003] When measuring the contact angle of a wire, water droplets need to be placed on an aluminum monofilament and then the contact angle is fitted. With ordinary contact angle measuring instruments, the instrument and the wire sample cannot be fixed together. Therefore, one experimenter needs to hold the wire sample in one hand and the measuring instrument in the other, constantly adjusting the position of the water droplet to ensure it lands precisely on the top of the aluminum monofilament, rather than in the gaps between the monofilaments. Simultaneously, another experimenter needs to adjust the brightness of the LED lights and operate the computer software to fit the measurement results. This measurement method eliminates the need for a base, and the internal casing does not form a sealed space. Therefore, the combined effect of the external light source and the internal LED lights may cause uneven brightness in the images captured by the camera, thus affecting the fitting results.

[0048] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0050] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0051] Example 1

[0052] Referring to Figures 4-8, the first embodiment of the present invention provides a contact angle measuring device for a conductor, comprising: a locking unit 100, including a connecting block 101, a pressing block 102 disposed inside the connecting block 101, a threaded sleeve assembly 103 disposed inside the pressing block 102, a sliding block 104 disposed at the end of the connecting block 101, and a limiting block 105 disposed on one side of the sliding block 104; and a clamping unit 200, including a mounting bracket 201. The mounting bracket 201 consists of a fixed clamping plate 202 located inside the mounting bracket 201, a movable clamping plate 203 located on top of the fixed clamping plate 202, a screw 204 located inside the connecting block 101, a sleeve 205 located on the outer side of the end of the screw 204, a pressure rod 206 located inside the sleeve 205, and a push rod 207 located at the end of the sleeve 205. The connecting block 101 is located on top of the mounting bracket 201. The screw 204 passes through the connecting block 101 and extends to its outer side.

[0053] Furthermore, the connecting block 101 has a cylindrical structure with large diameters at both ends and a smaller diameter in the middle; this structure ensures that the connecting block 101 can be positioned at the top of the mounting bracket 201 and will not detach from the mounting bracket 201.

[0054] The pressing block 102 has a circular structure, and its sidewall can contact the inner wall of the connecting block 101, thus ensuring that the pressing block 102 can move along the inside of the connecting block 101. The threaded sleeve assembly 103 is adapted to the pressing block 102. The threaded sleeve assembly 103 is located inside the pressing block 102, and there are multiple sets of threaded sleeve assemblies 103. When multiple sets of threaded sleeve assemblies 103 are combined, they can form a threaded sleeve structure that cooperates with the screw 204, so that the screw 204 can be fed along the internal thread structure formed by the threaded sleeve assembly 103.

[0055] The limiting block 105 can limit the position of the pressing block 102; thereby ensuring that the position of the multiple sets of threaded sleeve assemblies 103 is fixed inside the connecting block 101; thereby ensuring that when the screw 204 rotates and contacts the inner wall of the threaded sleeve assembly 103, the threaded sleeve assembly 103 can remain stationary in a far away position.

[0056] The end of the sliding block 104 passes through the connecting block 101, and the sliding block 104 is slidably connected to the limiting block 105, so as to better facilitate the movement of the sliding block 104 and thus drive the limiting block 105 to move, so that the limiting block 105 can release the limiting of the pressing block 102.

[0057] The connecting block 101 penetrates the mounting bracket 201 and extends to its outer side; both ends of the connecting block 101 have through holes, and the diameter of the through holes allows the screw 204 to penetrate the connecting block 101 and extend to the inner side of the connecting block 201; the screw 204 and the threaded sleeve assembly 103 form a threaded engagement; the threaded engagement between the screw 204 and the threaded sleeve assembly 103 enables the screw 204 to self-lock, thereby driving the movable clamping plate 203 to move closer to the fixed clamping plate 202; thus, the movable clamping plate 203 cooperates with the fixed clamping plate 202 to clamp and fix the wire;

[0058] The sleeve rod 205 is located on the pressure rod 206 and is supported by a certain means; pushing the pressure rod 206 can cause its bottom to press against the end of the sliding block 104, pushing the sliding block 104 to move in the vertical direction; the movement of the sliding block 104 in the vertical direction can drive the limiting block 105 to move in the horizontal direction; thereby achieving the purpose of the limiting block 105 moving away from the surface of the pressing block 102.

[0059] In use, to quickly clamp and fix the wire, the wire is passed through the mounting bracket 201 and placed between the mounting bracket 201 and the movable clamping plate 203. Then, the finger presses the lever 206, causing the bottom of the lever 206 to press against the end of the sliding block 104. The sliding block 104 moves vertically under pressure, causing the limiting block 105 to move horizontally, separating the limiting block 105 from the end face of the pressing block 102. Then, the sleeve lever 205 is pressed, causing the sleeve lever 205 to... By moving the push rod 207 at its end, after pressing down the sleeve rod 205, the finger pushing the pressure rod 206 can be released; as the sleeve rod 205 moves downward, it drives the push rod 207 to move; so that the push rod 207 can drive the pressing block 102 to move vertically; as the pressing block 102 moves, the side wall of the pressing block 102 can squeeze the end of the limiting block 105; thus, the limiting block 105 will not limit the pressing block 102; as the pressing block 102 moves vertically, it can drive the threaded sleeve Component 103 moves horizontally, allowing the multiple sets of movable clamping plates 203 to move away from each other; thus, the movable clamping plates 203 are no longer pressed against the outside of the screw 204; then, under the gravity of the screw 204, they move downwards, allowing the movable clamping plates 203 to fall above the wire; then, the finger pressing the sleeve rod 205 is released; under the elastic force of the elastic component, the pressing block 102 and the threaded sleeve assembly 103 can be reset; then, the position of the threaded sleeve assembly 103 can be adjusted by the set limiting block 105. The limit switch is set; then the screw 204 can be rotated, and the screw 204 is threadedly connected to the threaded sleeve assembly 103, so that the screw 204 is spirally fed in the vertical direction; then the movable clamping plate 203 can be moved, thereby pressing the wire between the fixed clamping plate 202 and the movable clamping plate 203; through the threaded engagement between the screw 204 and the threaded sleeve assembly 103, the screw 204 can be self-locked, so that the wire is fixedly clamped between the movable clamping plate 203 and the fixed clamping plate 202.

[0060] In summary, by cooperating with the screw and threaded sleeve assembly, the problem of slow screw feed efficiency can be effectively shortened; the clamping and fixing of the wire can be completed quickly, and the operation is simpler and more convenient in the clamping and installation of different wires.

[0061] Example 2

[0062] Referring to Figures 1 to 12, this is the second embodiment of the present invention, which differs from the first embodiment in that it further includes, in the previous embodiment, the contact angle measuring device for the wire, comprising: a pressing block 102 including a fixing block 102a disposed at its end, the fixing block 102a including a first sliding groove 102a-1 formed therein; a threaded sleeve assembly 103 including a first slider 103a disposed on its side wall, and a second slider 103b disposed at the bottom of the threaded sleeve assembly 103; the first sliding groove 102a-1 is adapted to the first slider 103a; the fixing block 102a and the threaded sleeve assembly 103 are slidably connected.

[0063] Preferably, there are multiple sets of fixing blocks 102a, and the multiple sets of fixing blocks 102a are distributed in a circumferential array along the end of the pressing block 102; the first slide groove 102a-1 is inclined; the first slider 103a has a trapezoidal structure and is adapted to the first slide groove 102a-1; the threaded sleeve assembly 103 is slidably connected to the fixing block 102a; the pressing block 102 can drive the threaded sleeve assembly 103 to move horizontally when it moves vertically.

[0064] Furthermore, the connecting block 101 has a hollow internal structure, and the pressing block 102 is adapted to the connecting block 101. The connecting block 101 includes a second sliding groove 101b opened at its bottom and a guide post 101c disposed inside the second sliding groove 101b. A first spring 101c-1 is sleeved on the outside of the guide post 101c. There are multiple sets of threaded sleeve assemblies 103, which are located inside the pressing block 102. The multiple sets of threaded sleeve assemblies 103 are combined to form a circular structure. The screw 204 is threadedly connected to the threaded sleeve assembly 103. The end of the first spring 101c-1 is in contact with the bottom of the fixing block 102a.

[0065] Preferably, the connecting block 101 has a hollow structure inside, which provides a certain space for the movement of the pressing block 102 and the threaded sleeve assembly 103. The second slider 103b moves along the trajectory inside the second slide groove 101b. There are multiple sets of threaded sleeve assemblies 103, which can be combined to form a cylindrical threaded sleeve structure. The combined threaded sleeve assembly 103 can be threadedly engaged with the screw 204. Through the threaded engagement between the screw 204 and the threaded sleeve assembly 103, the screw 204 can be self-locked. The first spring 101c-1 can push the fixing block 102a to move through the rebound force, thereby driving the pressing block 102 and the threaded sleeve assembly 103 to reset.

[0066] Furthermore, the connecting block 101 also includes a through groove 101a disposed on its end face, the through groove 101a including a third sliding groove 101a-1 opened on its side wall and a fourth sliding groove 101a-2 opened at the bottom of the through groove 101a; the sliding block 104 includes a third slider 104a disposed at its bottom and a fourth slider 104b disposed on both sides of the sliding block 104; the limiting block 105 includes a trapezoidal plate 105a disposed at its end, a second spring 105b disposed on one side of the limiting block 105, and a fifth slider 105c disposed at the bottom of the limiting block 105; the trapezoidal plate 105a has a fifth sliding groove 105a-1 opened on its inclined surface; the third slider 104a is adapted to the fifth sliding groove 105a-1.

[0067] Preferably, the sliding block 104 is located inside the through groove 101a, and the fourth slider 104b is adapted to the third slide groove 101a-1. Pressing the sliding block 104 can drive the fourth slider 104b to move along the vertical direction of the third slide groove 101a-1. The trapezoidal plate 105a is inclined, and the third slider 104a has a trapezoidal structure. The third slider 104a is adapted to the fifth slide groove 105a-1. Pressing down the sliding block 104 can drive the limiting block 105 to move along the horizontal direction. The second spring 105b is adapted to the fourth slide groove 101a-2. This ensures that the movement of the sliding block 104 along the vertical direction can drive the limiting block 105 to move along the horizontal direction of the fourth slide groove 101a-2.

[0068] Furthermore, the fifth slider 105c is adapted to the fourth slide groove 101a-2; the limiting block 105 is slidably connected to the connecting block 101; one end of the second spring 105b is connected to the limiting block 105, and the other end is connected to the inner wall of the through groove 101a; the end face of the limiting block 105 contacts the bottom surface of the pressing block 102, and the sliding block 104 passes through the through groove 101a and extends to its outer side.

[0069] Preferably, the second spring 105b can push the limiting block 105 to move when reset is required, through the rebound force of the second spring 105b; this allows the limiting block 105 to penetrate the side wall of the pressing block 102, and then the end face of the limiting block 105 to contact the surface of the pressing block 102; the limiting block 105 can restrict the pressing block 102 in the vertical direction; thereby ensuring that the position of the threaded sleeve assembly 103 remains unchanged after assembly; and thus achieving threaded engagement between the screw 204 and the threaded sleeve assembly 103.

[0070] Furthermore, the screw 204 is movably connected to the movable clamping plate 203; the sleeve 205 includes a connecting sleeve 205a disposed on its top outer side, a protrusion 205b disposed on the side wall of the sleeve 205, and a third spring 205c disposed at the bottom of the sleeve 205; the protrusion 205b has a through hole 205b-1 extending through its bottom; one end of the third spring 205c is connected to the connecting sleeve 205a, and the other end is connected to the end of the connecting block 101.

[0071] Preferably, the end of the screw 204 is movably connected to the movable clamping plate 203; the movable clamping plate 203 moves vertically along with the screw 204; the provided third spring 205c can connect the sleeve 205 to the connecting block 101; the provided third spring 205c can drive the sleeve 205 to reset; the sleeve 205 has a hollow structure inside and can move outside the screw 204.

[0072] Furthermore, the pressure rod 206 includes a fourth spring 206a disposed on its outer side; the pressure rod 206 is adapted to the through hole 205b-1; the pressure rod 206 passes through the through hole 205b-1 and extends to its outer side; the end of the fourth spring 206a contacts the inner wall of the through hole 205b-1; the bottom of the pressure rod 206 contacts the top of the sliding block 104.

[0073] Preferably, the through hole 205b-1 has a larger diameter at the top and a smaller diameter at the bottom. One end of the fourth spring 206b is connected to the top of the pressure rod 206, and the other end is fixedly connected to the bottom wall of the through hole 205b-1. By pressing down the pressure rod 206, its bottom can contact the top of the sliding block 104. Thus, the operator can move the sliding block 104 downward by pressing down the pressure rod 206.

[0074] Furthermore, the push rod 207 is fixedly connected to the protrusion 205b; the push rod 207 passes through the through groove 101a and extends into it; the bottom of the push rod 207 contacts the top of the pressing block 102; the pressing block 102 moves vertically, causing the threaded sleeve assembly 103 to move horizontally; multiple sets of threaded sleeve assemblies 103 move away from each other; the threaded sleeve assembly 103 is separated from the screw 204; the screw 204 also includes a force-applying rod 204a disposed at its end.

[0075] Preferably, the push rod 207 is fixedly connected to the protrusion 205b, and the push rod 207 passes through the through groove 101a and extends into the connecting block 101; the movement of the push rod 207 can push the pressing block 102 to move in the vertical direction; the movement of the pressing block 102 in the vertical direction can drive the threaded sleeve assembly 103 to move in the horizontal direction; when the push rod 207 moves downward to press the pressing block 102, the pressing block 102 moves in the vertical direction, which can drive multiple sets of threaded sleeve assemblies 103 to move in the horizontal direction, thereby causing the multiple sets of threaded sleeve assemblies 103 to move away from each other.

[0076] In normal use, multiple sets of threaded sleeve assemblies 103 are combined to form a threaded sleeve structure; the screw 204 can be threadedly engaged with the threaded sleeve assembly 103, and under the rebound force of the first spring 101c-1, it can push the pressing block 102 to move, so that the end of the pressing block 102 contacts the top of the inner wall of the connecting block 101; as the pressing block 102 moves vertically, it can drive the fixing block 102a to move; the first slide groove 102a-1 and the first slider 103a are adapted to each other; when the top of the pressing block 102 contacts the inner wall of the connecting block 101, the fixing block 102a can squeeze the multiple sets of threaded sleeve assemblies 103 to move horizontally, and the second slider 103b slides along the inner side of the second slide groove 101b; the multiple sets of threaded sleeve assemblies 103 come together to form a circular threaded sleeve structure; the pressing block 102 moves along the connecting block 101. During the vertical movement of the inner wall of 01, the side wall of the pressing block 102 can contact the inclined surface of the limiting block 105; the pressing block 102 moves vertically while pressing the limiting block 105, so that the end of the limiting block 105 is submerged in the side wall of the connecting block 101; when the top of the pressing block 102 contacts the inner wall of the connecting block 101, the side wall of the pressing block 102 no longer presses the end of the limiting block 105; then, under the rebound force of the second spring 105b, the limiting block 105 can be pushed to move horizontally along the fourth slide groove 101a-2; so that the surface of the limiting block 105 contacts the end face of the pressing block 102; thus, the position of the pressing block 102 can be limited by the limiting block 105; so that the pressing block 102 will not move vertically; the fixed position of the pressing block 102 fixes the position of the threaded sleeve composed of the threaded sleeve assembly 103;

[0077] When quick wire installation is required, pressing the pressure rod 206 causes it to move along the axis of the through hole 205b-1. As the pressure rod 206 is pressed down, the fourth spring 206a is compressed, and the pressure rod 206 moves downward so that its bottom contacts the top of the sliding block 104. Then, the pressure rod 206 pushes the sliding block 104 to move, causing the sliding block 104 to move vertically along the third slide groove 101a-1. The third slider 104a presses the trapezoidal plate 105a vertically, causing the trapezoidal plate 105a to move along the fourth slide groove 101a-1. 01a-2 moves horizontally; as the sliding block 104 moves downward, it gradually presses against the limiting block 105, causing the end of the limiting block 105 to move away from the surface of the pressing block 102, thereby releasing the limiting effect on the pressing block 102; then, the pressing rod 205 is pressed down, causing the pressing rod 205 to compress the third spring 205c; as the pressing rod 205 moves downward, it can drive the push rod 207 to move, causing the push rod 207 to press down on the pressing block 102; as the pressing block 102 moves downward, it can drive the threaded sleeve assembly 103 to move horizontally. Multiple sets of threaded sleeve assemblies 103 are moved away from each other, so that the threaded sleeve assemblies 103 no longer contact the screw 204; at this time, under the action of weight, the movable clamping plate 203 can be driven to contact the surface of the wire; at the same time, the screw 204 can be quickly pulled upward; the position of the movable clamping plate 203 can be flexibly adjusted; when the pressing block 102 is pressed downward, the side wall of the pressing block 102 can squeeze the end of the limiting block 105, at which time the operator can release the finger pressing the end of the pressing rod 206; after the wire contacts the movable clamping plate 203, the pressing block is released. The finger of the pressure rod 205, under the rebound force of multiple springs, can push the pressing block 102 and the threaded sleeve assembly 103 to reset; then the operator rotates the force rod 204a, so that the screw 204 moves along the threaded trajectory inside the threaded sleeve assembly 103; so that the screw 204 and the threaded sleeve assembly 103 are threadedly connected, and the screw 204 can form a self-locking mechanism through the threaded connection between the screw 204 and the threaded sleeve assembly 103; then the movable clamping plate 203 and the fixed clamping plate 202 can be used to clamp and fix the wire.

[0078] In summary, the present invention, through its detection unit, can be applied to the measurement of the contact angle of a conductor. The combination of the moving unit and the locking unit allows for rapid fixation of the conductor, ensuring that the conductor's position does not move arbitrarily during the contact angle measurement process. This further guarantees the accuracy of the contact angle measurement and also facilitates operation for staff, reducing their workload.

[0079] Example 3

[0080] Referring to Figures 1 to 6, this is the third embodiment of the present invention, which differs from the previous two embodiments in that it includes a detection unit 300, comprising a housing 301, a drive member 302 disposed inside the housing 301, a movable block 303 disposed outside the drive member 302, a syringe 304 disposed on the top of the housing 301, an illumination lamp 305 disposed inside the housing 301, and a camera 306 disposed on one side of the illumination lamp 305; the drive member 302 is adapted to the movable block 303; the sleeve 205 penetrates the top of the housing 301 and extends to its outer side; the syringe 304 penetrates the housing 301 and extends to its outer side.

[0081] Preferably, the number of driving components 302 is three sets, and the three sets of driving components 302 are located inside the housing 301 and are equidistantly distributed along the vertical direction; the driving components 302 are adapted to the movable blocks 303; the rotation of the driving components 302 can drive the movable blocks 303 to move along the vertical direction; the movable blocks 303 are connected to the mounting bracket 201; by driving the movable blocks 303 to move, the mounting bracket 201 can be driven to move along the vertical direction, thereby ensuring that the position of the wire corresponds to the camera 306; and then the contact angle of the wire can be measured.

[0082] Furthermore, the movable block 303 is connected to the mounting bracket 201; there are two sets of clamping units 200, which are symmetrically arranged inside the housing 301.

[0083] Preferably, there are two sets of clamping units 200, which can better facilitate the clamping and fixing of both ends of the wire; thus, the wire can be fixed inside the housing 301, and the syringe 304 is in contact with the middle set of movable blocks 303. The syringe 304 can be driven to move by the middle driving member 302, which makes it convenient for the staff to add solution into the syringe 304 or push the syringe 304 to drop the solution onto the wire.

[0084] In use, the aluminum wire passes through the slot on the housing 301 of the portable contact angle measuring instrument, and the clamping unit 200 is adjusted up and down to a suitable position by the drive component 302. Then, the wire is fixed inside the housing 301 by the clamping unit 200. By adjusting the drive component 302 to move the syringe 304, actions such as taking out the water drop syringe 304 to add water, adjusting its height, and fixing it to the surface of the housing 301 can be performed. By adjusting the clamping unit 200 and the drive component 302 to move the aluminum wire to a suitable position, the locking unit 100 can then cooperate with the clamping unit 200 to clamp and fix the wire. The water drop syringe 304 is adjusted to a suitable height by the drive component 302, and then the illumination lamp 305 is adjusted to a suitable brightness. The water drop syringe 304 drops water onto the surface of the aluminum wire, and the camera 306 inside the housing 301 captures the contact image between the water drop and the surface of the aluminum wire. The contact angle can be obtained by analyzing and fitting the image through software.

[0085] In summary, this invention addresses the unique shape and structure of aluminum stranded wires. The wire passes through the slot in the housing and is fixed by a clamping device. By using a water droplet syringe to apply water droplets to the surface of the aluminum wire, the contact angle of the aluminum wire surface can be measured conveniently, quickly, and accurately.
