Description

Technical Field

[0001] This utility model relates to the field of thin film thickness measurement technology, and in particular to a pressure thickness measurement device. Background Technology

[0002] With the development of the new energy industry, the application of porous and loosely structured materials is becoming increasingly common. Existing manufacturing processes require applying pressure to these materials; therefore, it is necessary to identify in advance the changes in porosity and thickness caused by potential collapse deformation under pressure in order to assess their performance.

[0003] A pressure thickness gauge is an instrument that measures the thickness of a material by applying pressure to its surface. In industry, especially in the new energy sector, it is commonly used to measure the thickness of battery cells and membrane materials (such as bare cells, finished cells, electrode sheets, and metal foils). These instruments include servo pressure thickness gauges that utilize servo motors and pressure gauges; pneumatic pressure thickness gauges that utilize compressed air cylinders and pressure gauges; and hydraulic thickness gauges that use hydraulic presses and hydraulic gauges. However, existing pressure thickness gauges suffer from drawbacks such as large size, heavy weight, and high cost. They also require a dedicated electrical, pneumatic, or hydraulic supply for measurement, and require significant resources in terms of personnel, space, and handling equipment when relocating them. Therefore, a solution to address these issues is urgently needed. Utility Model Content

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] This embodiment proposes a pressure thickness measurement device to solve the problems of poor portability and low adaptability of existing pressure thickness measurement devices.

[0033] like Figures 1-3 As shown, the pressure thickness measuring device includes a base 1, a mounting frame assembly 2, a measuring instrument 3, and a pressing member 4. The mounting frame assembly 2 is located on the upper side of the base 1. The pressing member 4 and the measuring instrument 3 are both movably mounted on the mounting frame assembly 2. The upper side of the base 1 has a working surface for placing the workpiece to be measured. The lower end of the pressing member 4 can press against the workpiece to be measured on the working surface. The measuring end 31 of the measuring instrument 3 abuts against the upper end of the pressing member 4, and the measuring instrument 3 can measure the thickness of the workpiece to be measured. The pressure thickness measuring device also includes multiple counterweight assemblies 5. One or some of the multiple counterweight assemblies 5 can be set on the pressing member 4 to increase the pressing force of the pressing member 4 against the workpiece to be measured. The pressure thickness measuring device also includes a universal level 6 and multiple support members 7. The universal level 6 is located on the upper side of the base 1, and the multiple support members 7 are arrayed on the lower side of the base 1 and can be raised and lowered relative to the base 1.

[0034] Understandably, existing pressure thickness measurement devices generally apply a preset pressure to the workpiece using a hydraulic press, servo motor, or cylinder, and then measure the thickness of the pressurized workpiece. However, the hydraulic press, servo motor, or cylinder have a large structural weight and occupy a lot of space, resulting in poor portability of the pressure thickness measurement device. Moreover, the site requires power, air, or oil to drive the hydraulic press, servo motor, or cylinder, resulting in low adaptability of the pressure thickness measurement device to different scenarios.

[0035] Therefore, this embodiment proposes a pressure thickness measuring device. By providing a base 1 with a working surface, the workpiece to be measured can be placed on the base 1. The pressure member 4 can have its pressure on the workpiece changed by adding a counterweight component 5, allowing the measuring instrument 3 to measure the thickness of the workpiece under different pressures. Furthermore, the number of counterweight components 5 can be changed as needed according to experimental requirements. Therefore, no driving components or driving energy are required on-site to activate the pressure member 4, thus changing the pressure on the workpiece and greatly increasing the adaptability of the pressure thickness measuring device. In addition, the counterweight components 5 are easy to carry, increasing the portability of the pressure thickness measuring device. This embodiment also features a height-adjustable support component 7 arrayed on the lower side of the base 1. This allows for the raising and lowering of different support components 7 based on the bubble position of the universal level 6, ensuring the pressure thickness measuring device remains as level as possible, improving measurement accuracy, and ultimately enhancing user satisfaction.

[0036] For example, measuring instrument 3 is an ultrasonic thickness gauge. This type of thickness gauge has high measurement accuracy and efficiency, improving the reliability of the pressure thickness measurement device. Of course, in other embodiments, other types of thickness gauges can also be selected as needed, depending on the type of part to be measured; no further restrictions are imposed here.

[0037] Optionally, the support member 7 includes a foot 71 and a support part 72. The support part 72 is located at the upper end of the foot 71, and is rod-shaped with external threads on its outer periphery. The base 1 has multiple threaded holes on its lower side, each corresponding to and engaging with the support part 72. This configuration allows the foot 71 to rise or fall relative to the base 1 by rotating the support part 72. This adjustment is made according to whether the bubble position of the universal level 6 is centered, keeping the pressure thickness measuring device as level as possible and improving the accuracy of thickness measurement.

[0038] For example, the foot 71 is a circular plate, and the support 72 is a column. This arrangement allows the support 7 to have a smoother shape and is easier to rotate, thus improving operability.

[0039] Optionally, the mounting bracket assembly 2 includes a support column 21, a mounting member 22, and a locking member 23. The support column 21 extends vertically and is disposed on the upper side of the base 1. The mounting member 22 extends horizontally and has a sliding hole at one end. The support column 21 and the sliding hole are slidably engaged. The locking member 23 is disposed on the mounting member 22 and can tighten the sliding hole to lock the support column 21. The pressure member 4 and the measuring instrument 3 are disposed at the other end of the mounting member 22. This arrangement, through the sliding engagement of the support column 21 and the sliding hole, enables the mounting member 22 to be raised and lowered, and the support column 21 can be locked by the locking member 23. This facilitates fixing the height of the pressure member 4 and the measuring instrument 3, and also facilitates the inspection and replacement of the pressure member 4 by raising and lowering the mounting member 22, thus improving the structural rationality of the pressure thickness measuring device.

[0040] For example, the mounting member 22 is rectangular plate-shaped. One end of the mounting member 22 has a sliding hole along the thickness direction, and the same end has a tightening groove extending through the thickness direction. The tightening groove is horizontally connected between the sliding hole and the outside of the mounting member 22. The locking member 23 has an operating part and a locking part connected to each other. The locking part is rod-shaped and has external threads. The mounting member 22 has threaded holes on both sides of the tightening groove. The locking part mates with the two threaded holes and passes through the tightening groove. This arrangement allows the locking part to move in the threaded holes by turning the operating part, thereby reducing the width of the tightening groove and the circumference of the sliding hole, thus tightening the sliding hole to lock the support column 21.

[0041] Optionally, the pressing member 4 includes a rod 41 and a pressing part 42. The rod 41 extends vertically, with its upper end abutting against the measuring end 31 of the measuring instrument 3 and its lower end connected to the pressing part 42. The counterweight assembly 5 has a through hole that mates with the rod 41, and the pressing part 42 can support the counterweight assembly 5. This design facilitates the installation of the counterweight assembly 5 and the pressing member 4, and improves the efficiency of installation and replacement, thus enhancing the structural rationality of the pressure thickness measuring device.

[0042] Optionally, the pressure thickness measuring device also includes a bearing 8 and a fixing member 9. Both the bearing 8 and the fixing member 9 are mounted on the mounting frame assembly 2. The mounting frame assembly 2 has a mounting hole, and the fixing member 9 has a connecting hole. From top to bottom, the connecting hole, the mounting hole, and the central hole of the bearing 8 are coaxially connected. The measuring end 31 of the measuring instrument 3 is inserted into the connecting hole, and the rod 41 passes through the central hole and the mounting hole of the bearing 8 and is inserted into the connecting hole, abutting against the measuring end 31 of the measuring instrument 3. Understandably, this arrangement allows the rod 41 of the pressing member 4 to be inserted from below into the central hole of the bearing 8, then pass through the mounting hole and extend into the connecting hole, while the measuring end 31 of the measuring instrument 3 is inserted into the connecting hole and abuts against the upper end of the rod 41. This arrangement facilitates the disassembly and installation of the pressing member 4 and the measuring instrument 3, improving the structural rationality of the pressure thickness measuring device.

[0043] For example, the fixing member 9 is installed on the upper side of the end of the mounting member 22 away from the sliding hole, and the bearing 8 is installed on the lower side of the end of the mounting member 22 away from the sliding hole. The measuring instrument 3 also includes a protective member 32, which is disposed on the lower side of the measuring instrument 3 and has a through hole. The protective member 32 is inserted into the connecting hole, and the measuring end 31 of the measuring instrument 3 extends out from the through hole. This arrangement can protect the measuring end 31 of the measuring instrument 3 and allow the mounting member 22 to be raised and lowered when the pressure member 4 is disassembled or assembled, so as to leave more space for the upper end of the rod 41 of the pressure member 4 to be inserted upward into the middle hole of the bearing 8. In addition, this arrangement allows the mounting member 22 to accommodate pressure members 4 of various lengths, improving the structural rationality of the pressure thickness measuring device.

[0044] Optionally, the pressure thickness measuring device also includes a locking member 10, which includes a holding part and an actuating part connected to each other. The actuating part is rod-shaped and has external threads. The fixing member 9 has a threaded hole that is perpendicular to and communicates with the connecting hole. The actuating part and the threaded hole cooperate and can abut against the protective member 32 of the measuring instrument 3. This setting allows the protective member 32 to be locked or released by turning the holding part, thereby preventing the measuring instrument 3 from falling off and improving the reliability of the pressure thickness measuring device.

[0045] Optionally, the pressing part 42 is frustum-shaped, with its larger end connected to the lower end of the rod 41, and its smaller end able to press against the workpiece to be measured. This arrangement allows the pressing part 42 to better support the counterweight assembly 5, and the frustum-shaped pressing part 42 can provide a wider range of pressure, thereby reducing the weight of the counterweight assembly 5 and further improving the pressurization range and portability of the pressure thickness measuring device.

[0046] Optionally, multiple pressure members 4 are provided, and the small end diameter of the pressure part 42 of different pressure members 4 is different. Multiple pressure members 4 can be selected to be installed on the mounting bracket assembly 2. Due to the different pressure requirements of different test pieces, the size requirements of the lower end of the pressure member 4 are also different. This setting can make the pressure member 4 adaptable to more types of test pieces, thereby improving the adaptability of the pressure thickness measuring device and user satisfaction.

[0047] For example, the large end diameter of the frustum-shaped pressing part 42 is 10mm-14mm, and the small end diameter is 1mm-3mm. This arrangement allows the pressing part 42 to balance the load-bearing stability of the counterweight component 5 and the pressing strength of the pressing member 4, thereby improving the structural rationality of the pressure thickness measuring device.

[0048] Of course, in other embodiments, the size range of the large end and the small end of the pressing part 42 is not limited to this. It can be adjusted as needed according to the usage requirements, and no further restrictions are imposed here.

[0049] Optionally, the counterweight assembly 5 includes two abutting counterweights, each with a groove on one side facing the other, forming a through hole. This arrangement allows for the disassembly or installation of the counterweight assembly 5 on the rod 41 of the pressing member 4 by separating or merging the two counterweights, improving installation efficiency and thus enhancing the reliability of the pressure thickness measuring device.

[0050] For example, the counterweight is provided with a magnetic attraction element. This feature makes it less likely for the counterweight to detach when assembled into counterweight assembly 5, thereby improving the installation stability of counterweight assembly 5 and thus improving the reliability of counterweight assembly 5 in use.

[0051] Optionally, the counterweight assembly 5 is cylindrical, and the two counterweights have the same shape and a semi-circular cross-section. This design makes the counterweight assembly 5 have a smoother surface, facilitating disassembly. In addition, this design ensures that the center of gravity of the counterweight assembly 5 coincides with the center of gravity of the pressing member 4, improving the stability of the counterweight assembly 5 when installed on the pressing member 4.

[0052] Optionally, the counterweight assembly 5 can be configured in multiple groups, with each group comprising multiple counterweight assemblies 5, and the weights of the counterweight assemblies 5 in different groups being different. This configuration allows for flexible combination of counterweight assemblies 5 according to test requirements, using counterweight assemblies 5 of different weights or multiple counterweight assemblies 5 of the same weight, thereby increasing the pressure range of the pressure thickness measuring device and improving its adaptability.

[0053] Optionally, the upper or lower end of the counterweight component 5 is provided with an annular protrusion, and the lower or upper end of the counterweight component 5 is provided with an annular groove, with the annular protrusion of adjacent counterweight components 5 cooperating with the annular groove. This arrangement creates a mating structure between the counterweight components 5, improving the connection stability when stacking different counterweight components 5, thereby enhancing the reliability of the pressure thickness measuring device.

[0054] For example, the width of the annular groove of the counterweight component 5 is 1mm-1.4mm, and the depth is 0.5mm-1.5mm. This setting can improve the connection stability between the counterweight components 5, while avoiding the counterweight components 5 being too light or having poor structural strength, thereby improving the reliability of the pressure thickness measuring device.

[0055] Of course, in other embodiments, the width and depth of the annular groove are not limited to this, and can be set as needed according to actual requirements, without too many restrictions here.

[0056] Optionally, a grip 33 is also provided on the upper part of the measuring instrument 3. This feature allows the user to easily pick up and hold the measuring instrument 3, improving the user experience.

[0057] For example, the grip 33 is cylindrical and extends vertically. Since the measuring instrument 3 is relatively compact, the cylindrical grip 33 makes it easy for people to hold with their fingers, further improving the user experience.

[0058] Optionally, the pressure thickness measuring device also includes a worktable 20, which is disposed at the upper end of the working surface and is used to support the workpiece to be tested. This arrangement not only increases the height of the workpiece to be tested, making it easier for the pressing component 4 to press it down, but also allows the worktable 20 to be replaced if it is damaged during a high test intensity, thus avoiding damage to the base 1 and improving the reliability of the pressure thickness measuring device.

[0059] For example, the worktable 20 is made of ceramic. This design makes the worktable 20 more durable and waterproof and fireproof. When the test piece is subjected to pressure and causes a flame explosion or liquid leakage, the worktable 20 remains unaffected, thus improving the reliability of the pressure thickness measurement device.

[0060] Of course, in other embodiments, the workbench 20 can also be made of other components, which can be selected as needed according to the test scenario, and no further restrictions are imposed here.

[0061] The usage process of the pressure thickness gauge in this embodiment is as follows:

[0062] First, observe whether the bubble position of the universal level 6 is centered. If not, rotate the support 7 at a specific position to make adjustments. Clean the workbench 20 and the pressure member 4 with a lint-free cloth. After calculating the required pressure of the test piece, select a suitable pressure member 4 and determine the weight and quantity of the counterweight assembly 5.

[0063] Then, pinch the grip 33 to adjust the height of the measuring instrument 3 so that the measuring end 31 of the measuring instrument 3 contacts the upper end of the rod 41 of the pressing part 4. After zeroing the measuring instrument 3, lift the pressing part 4 several times to confirm that the reading of the measuring instrument 3 is zero when the pressing part 4 is in place. Add one counterweight component 5 at a time. Since the weight of the counterweight component 5 will cause a slight deformation of the workbench 20 after each addition, it is necessary to record the reading of the measuring instrument 3 after each addition so that the measurement result can be added to the measurement result to eliminate deformation error.

[0064] Finally, remove the counterweight assembly 5, lift the pressure member 4, place the test piece on the workbench 20, lower the pressure member 4, and install the counterweight assembly 5 onto the pressure member 4. After the reading of the measuring instrument 3 stabilizes, record the measurement value. Then, remove the counterweight assembly 5 and remove the pressure member 4, remove the test piece, clean the workbench 20 and the pressure member 4, zero the reading of the measuring instrument 3, and proceed with the measurement of the next test piece. After all test pieces have been measured, clean the pressure member 4 and the workbench 20, and turn off the power of the measuring instrument 3.

[0065] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
