Description

Technical Field

[0001] The invention belongs to the technical field of edge pressing testing machines, in particular to a tempered film edge pressing testing machine. Background Art

[0002] The tempered film edge pressing tester is a device used to test the edge pressing performance of tempered film and other products. It uses touch screen control and display, can test the edge pressing force value of the product, and is equipped with a micro printer to print test data. By replacing the pressure heads of different specifications, you can freely choose to test in the air or non-air, thereby realizing the evaluation of the edge strength and wear resistance of the tempered film.

[0003] In the prior art, the product's edge clamping force is tested through touch screen control and display. When working, the test machine applies a certain pressure to the edge of the tempered film, monitors and records the force changes during the edge clamping process, and prints the test data through the equipped micro printer, thereby evaluating the strength and wear resistance of the edge of the tempered film.

[0004] There are still some problems in the actual application of the above scheme. When performing the edge pressing test on the tempered film, the probe and the pressure rod need to be installed. During the installation process, the operator mainly uses the naked eye to judge whether the center positions of the probe and the pressure rod are aligned. However, human vision has certain limitations. It is easy to produce errors when judging the alignment of the center positions of the probe and the pressure rod, which will cause the centers of the probe and the pressure rod to be not on the same straight line. This will cause the applied force to be unable to be evenly transmitted to the tempered film, and this uneven force transmission will cause the deformation and stress distribution of the tempered film during the edge pressing process, thereby affecting the accuracy of the measurement results. Secondly, during the use of the added rotation adjustment mechanism, the probe needs to be adjusted to different positions due to process requirements. At this time, the use of the rotation adjustment mechanism will produce pulling forces in different directions on the placement plate. Therefore, the direction of the pulling force on the placement plate will change due to the different positions of the probe, which will cause the placement plate to be offset, thereby affecting the contact state between the probe and the tempered film, which will lead to increased errors during the test and even test failure.

[0005] To this end, the present invention provides a tempered film edge pressing testing machine. Summary of the invention

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figures 1 to 8 As shown, a tempered film edge pressing test machine described in an embodiment of the present invention includes an edge pressing test device 1, the edge pressing test device 1 includes an operating table 101, a first electric guide rail 102 is fixedly connected to the upper part of the operating table 101, a first slider 103 is slidably connected in the first electric guide rail 102, a pressure rod 104 is fixedly connected to the bottom of the first slider 103, a placement plate 105 is arranged above the operating table 101, a plurality of guide holes are opened through the upper part of the placement plate 105, and the guide holes have different sizes, the placement plate 105 is composed of a vertical plate and a horizontal plate, a probe 106 is inserted into the guide hole opened on the upper part of the placement plate 105, and a rotation adjustment mechanism 2 is arranged on the outer ring surface of the edge pressing test device 1;

[0036] The rotation adjustment mechanism 2 includes a limit plate 208 fixedly arranged at the bottom of the pressure rod 104, a second rotating plate 213 is rotatably arranged inside the limit plate 208, and a plurality of groups of rotating plates 211 are slidably arranged above the second rotating plate 213. Through the aggregation of the plurality of rotating plates 211, the pressure rod 104 can be kept in the same vertical line with the center of the probe 106 when pressed down, thereby improving the uniformity of the pressure applied to the edge of the tempered film.

[0037] Specifically, when performing the edge pressing test on the tempered film, the probe 106 and the pressure rod 104 need to be installed. During the installation process, the operator mainly uses the naked eye to judge whether the center positions of the probe 106 and the pressure rod 104 are aligned. However, human vision has certain limitations, and errors are easily generated when judging the alignment of the center positions of the probe 106 and the pressure rod 104, so that the centers of the probe 106 and the pressure rod 104 are not on the same straight line, which will cause the applied force to be unable to be uniformly transmitted to the tempered film, and this uneven force transmission will cause deformation of the tempered film during the edge pressing process and uneven stress distribution, thereby affecting the accuracy of the measurement results;

[0038] Therefore, the present invention solves this problem by setting a corresponding structure. In the tempered film edge pressing tester described in the present invention, when it is necessary to perform an edge pressing test on the tempered film, the first electric guide rail 102 fixed on the upper part of the operating table 101 is started. At this time, the first electric guide rail 102 will drive the first slider 103 to move downward. Since the top of the pressure rod 104 is fixed to the bottom of the first slider 103, the pressure rod 104 will move synchronously when the first slider 103 moves. At this time, the staff will place the placement plate 105 with the tempered film directly under the first slider 103, and select a probe 106 of a suitable size according to the test requirements and insert it into the hole of the corresponding size on the top of the placement plate 105, so that the bottom of the probe 106 fits with the edge of the tempered film. At the same time, it is necessary to ensure that the probe 106 is at the bottom of the pressure rod 104. At this time, the first slider 103 will continue to drive the pressure rod 104 to apply pressure to the probe 106, and the pressure applied to the probe 106 will be transmitted to the edge of the tempered film placed on the transverse plate of the placement plate 105 and the pressure rod 106. The rod 104 is installed, and during the installation process, the operator mainly uses the naked eye to judge whether the center positions of the probe 106 and the pressure rod 104 are aligned. However, human vision has certain limitations, and errors are easily generated when judging the alignment of the center positions of the probe 106 and the pressure rod 104, which will cause the centers of the probe 106 and the pressure rod 104 to be not in the same straight line, which will cause the applied force to be unable to be evenly transmitted to the tempered film, and this uneven force transmission will cause the deformation and stress distribution of the tempered film during the edge pressing process, thereby affecting the accuracy of the measurement results. At this time, the movement of the pressure rod 104 drives the limit plate 208 to move synchronously, and stops moving when the bottom of the pressure rod 104 is in contact with the top of the probe 106. At this time, the rotation of the second rotating disk 213 drives the several groups of rotating plates 211 sliding above it to aggregate, so that the pressure rod 104 can be kept in the same vertical line with the center of the probe 106 when pressing down, thereby improving the uniformity of the pressure applied to the edge of the tempered film, and then improving the accuracy of the test results.

[0039] Embodiment 2

[0040] like Figures 2 to 8 As shown in Comparative Example 1, another embodiment of the present invention is:

[0041] like Figure 2 and Figure 3 As shown, the rotation adjustment mechanism 2 described in this embodiment includes a fixed disk 201, and the fixed disk 201 is fixedly connected to the outer ring surface of the pressure rod 104. The outer ring surface of the fixed disk 201 is rotatably connected to the first rotating disk 202, and the outer ring surface of the pressure rod 104 is fixedly connected to the fixed ratchet 203, and the second fixed plate 215 and the first fixed plate 207 are inserted with pins 216 in the guide holes.

[0042] Specifically, when it is necessary to perform edge pressure detection on the edge of the tempered film, the pin 216 is inserted into the guide holes opened inside the second fixed plate 215 and the first fixed plate 207, and the first rotating disk 202 is rotated at the same time. Since the fixed disk 201 and the first rotating disk 202 are rotating, the synchronous rotation of the first rotating disk 202 will not affect the normal operation of the pressure rod 104. At the same time, since the first slider 103 is fixed on the outer ring surface of the pressure rod 104, the fixed ratchet 203 will not rotate when the first rotating disk 202 rotates.

[0043] like Figure 3 As shown, in this embodiment, an inner cavity is opened inside the first rotating disk 202, and a fixed shaft 204 is fixedly connected to the top of the inner cavity of the first rotating disk 202. A rotating ratchet 205 is rotatably connected to the outer ring surface of the fixed shaft 204. The rotating ratchet 205 is meshed with the teeth of the fixed ratchet 203. A telescopic spring 206 is fixedly connected to the side of the rotating ratchet 205. The other end of the telescopic spring 206 is fixedly connected to the inner ring surface of the first rotating disk 202. The outer ring surface of the first rotating disk 202 is fixedly connected to the first fixed plate 207.

[0044] Specifically, when the first rotating disk 202 rotates, it will drive the fixed shaft 204 to move synchronously. Since the rotating ratchet 205 rotates on the outer ring surface of the fixed shaft 204, the rotating ratchet 205 and the telescopic spring 206 fixed on the side of the rotating ratchet 205 will also move synchronously. When the rotating ratchet 205 encounters the teeth on the outer ring surface of the fixed ratchet 203, it will rotate around the fixed shaft 204 away from the fixed ratchet 203, and at the same time squeeze the telescopic spring 206. When the rotating ratchet 205 is engaged with the fixed ratchet 203, the rotating ratchet 205 will be affected by the reset of the telescopic spring 206 and re-engaged, so that the entire mechanism can achieve the purpose of self-locking and avoid loosening due to external factors during the operation of the entire device.

[0045] like Figure 4 and Figure 5As shown, the inner ring surface of the limit plate 208 in this embodiment is rotatably connected to the second rotating plate 213, a sliding groove 214 is opened on the upper part of the second rotating plate 213, and the outer ring surface of the second rotating plate 213 is fixedly connected to the second fixed plate 215, and guide holes are opened through the second fixed plate 215 and the first fixed plate 207, the limit block 212 is slidably connected in the sliding groove 214, and the bottom of one side of the rotating plate 211 is fixedly connected to the limit block 212.

[0046] Specifically, before the first rotating disk 202 rotates, the probe 106 has been inserted into the hole through the upper part of the placement plate 105, and the top of the probe 106 is in the space formed by multiple groups of rotating plates 211. At this time, the rotation of the first rotating disk 202 will drive the pin 216 to move synchronously through the first fixed plate 207, and at the same time drive the second fixed plate 215 to move, and then drive the sliding groove 214 opened on the upper part of the second rotating disk 213 to move. The rotation of the sliding groove 214 can provide power support for the subsequent aggregation and diffusion of multiple groups of rotating plates 211.

[0047] like Figure 6 As shown, the rotation adjustment mechanism 2 described in this embodiment includes a limiting plate 208, and the limiting plate 208 is fixedly connected to the bottom of the pressure rod 104. An oblique guide groove 209 is opened inside the limiting plate 208. A sliding column 210 is slidably connected inside the oblique guide groove 209, and a rotating plate 211 is fixedly connected to the bottom of the sliding column 210.

[0048] Specifically, when the sliding groove 214 rotates, it will drive the limit block 212 sliding in the sliding groove 214 and the rotating plate 211 fixed on the top of the limit block 212 to move synchronously. At the same time, since the sliding column 210 fixed on the upper part of the rotating plate 211 is limited by the oblique guide groove 209, when moving, the rotating plate 211 will be guided inward by the sliding column 210 fixed on its top. The guide of the oblique guide groove 209, when the rotating plate 211 is in contact with the outer annular surface of the probe 106, the first slider 103 will move downward through the drive of the first electric guide rail 102 and apply pressure to the probe 106. At this time, the convergent movement of multiple groups of rotating plates 211 can make the centers of the pressure rod 104 and the probe 106 on the same horizontal plane, thereby improving the uniformity of the pressure applied to the edge of the tempered film, and then improving the accuracy of the test results.

[0049] like Figure 7 and Figure 8As shown, the upper part of the edge pressing test device 1 described in this embodiment is provided with a reciprocating leveling mechanism 3 for leveling, and the reciprocating leveling mechanism 3 includes a second electric guide rail 301, a second slider 302 is slidably connected inside the second electric guide rail 301, a leveling plate 303 is fixedly connected to the side of the second slider 302, a reference plate 304 is fixedly connected to one end of the second electric guide rail 301, an inner cavity is opened in the transverse plate of the placement plate 105, a reciprocating spring 305 is fixedly connected to the side wall of the inner cavity of the placement plate 105, and an L-shaped limit plate 306 is fixedly connected to one end of the reciprocating spring 305.

[0050] Specifically, before the rotation adjustment mechanism 2 is operated, the L-shaped limit plate 306 is pulled, and the tempered film is placed on the horizontal plate of the placement plate 105. At this time, the L-shaped limit plate 306 is released and the reciprocating spring 305 is not affected by external force and will reset, and the tempered film of the corresponding size is limited to the horizontal plate of the placement plate 105 through the L-shaped limit plate 306 to avoid the displacement of the tempered film when the placement plate 105 moves. When the limit of the tempered film is completed, the second electric guide rail 301 is started. At this time, the second slider 302 is displaced under the drive of the second electric guide rail 301, and the adjustment plate 303 fixed on its side will be driven to move synchronously during the movement, and will fit with the side of the L-shaped limit plate 306 during the movement. However, at this time, the second electric guide rail 301 will continue to drive the second slider 302 to move, and the placement plate 105 is pushed by the adjustment plate 303, and its side surface will gradually contact the side surface of the reference plate 304. At this time, the second electric guide rail 301 stops working, and the pressure rod 104 will be pressed down again. The movement of the adjustment plate 303 can avoid the placement plate 105 from being offset when the rotating adjustment mechanism 2 is working, thereby avoiding errors caused by the offset of the placement plate 105. At the same time, the limitation of the adjustment plate 303 can avoid the placement plate 105 from being offset during the test, and the test needs to be interrupted for adjustment, thereby improving the test efficiency and further improving the accuracy of the test results.

[0051] Working principle: when it is necessary to perform edge pressure detection on the edge of the tempered film, insert the pin 216 into the guide holes opened inside the second fixed plate 215 and the first fixed plate 207, and rotate the first rotating disk 202 at the same time. Since the fixed disk 201 and the first rotating disk 202 are rotating, the synchronous rotation of the first rotating disk 202 will not affect the normal operation of the pressure rod 104. At the same time, since the first slider 103 is fixed on the outer ring surface of the pressure rod 104, the fixed ratchet 203 will not rotate when the first rotating disk 202 rotates.

[0052] When the first rotating disk 202 rotates, it will drive the fixed shaft 204 to move synchronously. Since the rotating ratchet 205 rotates on the outer ring surface of the fixed shaft 204, the rotating ratchet 205 and the telescopic spring 206 fixed on the side of the rotating ratchet 205 will also move synchronously. When the rotating ratchet 205 encounters the teeth on the outer ring surface of the fixed ratchet 203, it will rotate around the fixed shaft 204 away from the fixed ratchet 203, and at the same time squeeze the telescopic spring 206. When the rotating ratchet 205 engages with the fixed ratchet 203, the rotating ratchet 205 will be affected by the reset of the telescopic spring 206 and re-engaged, so that the entire mechanism can achieve the purpose of self-locking and avoid loosening due to external factors during the operation of the entire equipment.

[0053] Before the first rotating disk 202 rotates, the probe 106 has been inserted into the hole through the upper part of the placement plate 105, and the top of the probe 106 is in the space formed by the multiple groups of rotating plates 211. At this time, the rotation of the first rotating disk 202 will drive the pin 216 to move synchronously through the first fixed plate 207, and at the same time drive the second fixed plate 215 to move, and then drive the sliding groove 214 opened on the upper part of the second rotating disk 213 to move. The rotation of the sliding groove 214 can provide power support for the subsequent aggregation and diffusion of the multiple groups of rotating plates 211.

[0054] When the sliding groove 214 rotates, it will drive the limit block 212 sliding in the sliding groove 214 and the rotating plate 211 fixed on the top of the limit block 212 to move synchronously. At the same time, since the sliding column 210 fixed on the upper part of the rotating plate 211 is limited by the oblique guide groove 209, when moving, the rotating plate 211 will converge inward along the guidance of the oblique guide groove 209 through the sliding column 210 fixed on its top. When the rotating plate 211 is in contact with the outer annular surface of the probe 106, the first slider 103 will move downward through the drive of the first electric guide rail 102 and apply pressure to the probe 106. At this time, the convergent movement of multiple groups of rotating plates 211 can make the centers of the pressure rod 104 and the probe 106 on the same horizontal plane, thereby improving the uniformity of the pressure applied to the edge of the tempered film, and then improving the accuracy of the test results.

[0055] Before the rotation adjustment mechanism 2 is operated, the L-shaped limit plate 306 is pulled and the tempered film is placed on the horizontal plate of the placement plate 105. At this time, the L-shaped limit plate 306 is released and the reciprocating spring 305 is not affected by the external force and will reset, and the tempered film of the corresponding size will be limited to the horizontal plate of the placement plate 105 through the L-shaped limit plate 306 to avoid the displacement of the tempered film when the placement plate 105 moves. When the limitation of the tempered film is completed, the second electric guide rail 301 is started. At this time, the second slider 302 is displaced under the drive of the second electric guide rail 301, and the adjustment plate 303 fixed on its side will be driven to move synchronously during the movement. During the movement, it will fit with the side of the L-shaped limit plate 306, but this At the same time, the second electric guide rail 301 will continue to drive the second slider 302 to move, and the placement plate 105 is pushed by the adjustment plate 303, and its side surface will gradually contact the side surface of the reference plate 304. At this time, the second electric guide rail 301 stops working, and the pressure rod 104 will be pressed down again. The movement of the adjustment plate 303 can avoid the placement plate 105 from being offset when the rotating adjustment mechanism 2 is working, thereby avoiding the error caused by the offset of the placement plate 105. At the same time, the limitation of the adjustment plate 303 can avoid the placement plate 105 from being offset during the test, and the test needs to be interrupted for adjustment, thereby improving the test efficiency and further improving the accuracy of the test results.

[0056] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention.
