Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of carrier tape peel force test, especially relates to a carrier tape peel force test structure for pressure sensor. BACKGROUND

[0002] The carrier tape peel force refers to the force required to peel the carrier tape from the backing material under certain conditions, and is one of the important indicators for measuring the adhesive properties of adhesive tape or similar adhesive materials.

[0003] The patent document with the application number 201920968861.7 discloses a carrier tape peel force tester, which comprises a support base plate, one end of the support base plate is connected with one end of a first limiting plate, the other end is connected with one end of a second limiting plate, and both are perpendicular to the support base plate; the distance between the two ends of the first limiting plate is less than the distance between the two ends of the second limiting plate; a guide rail and a transmission shaft are arranged between the first limiting plate and the second limiting plate; a connecting plate is arranged on the guide rail; a transmission device is arranged on the guide rail, and the transmission device is connected with one side of the connecting plate; a switch is arranged on the other side of the connecting plate, and the output end of the switch is connected with the input end of the transmission device; a gravimeter is arranged on the other side of the connecting plate; a hook of the gravimeter is provided with a clamp.

[0004] However, in actual application, the traditional test structure does not have the function of auxiliary supporting the carrier tape in the peeling area when in use. Since the carrier tape has a certain weight, it will be twisted or entangled when placed naturally. The twisting and entangling of the carrier tape will affect the data when the carrier tape is peeled. This not only reduces the accuracy of the structure when peeling the carrier tape, but also may cause poor stability and low test efficiency of the peeling structure when testing.

[0005] For example, when peeling the carrier tape, the carrier tape will be twisted and deformed due to gravity. When the peeling mechanism peels the twisted and deformed carrier tape, more pulling force is required, which affects the real data when peeling the carrier tape. This not only reduces the accuracy of the data when the peeling structure peels the carrier tape, but also prolongs the test time and affects the test efficiency of the structure. Utility model content

[0006] The utility model discloses a kind of test structures of stripping force for pressure sensor's carrier tape, to solve in practical application, traditional test structure does not have the function of auxiliary support to the carrier tape of peeling area when using, since carrier tape has certain weight, in natural drop placement, it can be twisted or wound, the twist and winding of drop can cause certain influence to the data when carrier tape peeling, these not only reduce the precision of structure to carrier tape peeling test, also possibly lead to the technical problems of poor stability and low test efficiency when peeling structure test.

[0007] In order to achieve the above object, the utility model adopts the following technical scheme:

[0008] A kind of test structures of stripping force for pressure sensor's carrier tape, including test mechanism and the auxiliary mechanism of assembly in the one side of test mechanism, the test mechanism includes test slide rail, the bottom of the test slide rail is fixedly installed with base, the front side of the top of the base is fixedly installed with bottom clamping plate, the front side of the inside of the test plate is fixedly installed with pressure probe by fixed seat, the outside of the test plate is equipped with the test frame for use with pressure probe, the bottom of the test frame is fixedly installed with the top clamping plate for use with bottom clamping plate;The auxiliary mechanism includes the auxiliary slide rail of installation in the one side of test slide rail, the front side of the auxiliary plate is slidably installed with the front side of the auxiliary plate, the front side of the wheel seat is fixedly installed with bottom unidirectional wheel.

[0009] In the scheme, when testing the carrier tape, the bottom unidirectional wheel and the top unidirectional wheel can support and clamp the test area of the carrier tape. The connection ends of the carrier tape can be quickly connected to the bottom clamping plate and the top clamping plate by supporting and clamping the test area of the carrier tape. The test slide rail can lift the test frame to peel the carrier tape. The pressure probe can detect the pressure when the test frame peels the carrier tape. The bottom unidirectional wheel and the guide plate can support the test area of the carrier tape to prevent distortion and winding when the carrier tape naturally falls during testing, which affects the peeling detection quality. The top unidirectional wheel can guide and limit the feeding path of the carrier tape during peeling test to prevent the carrier tape from tilting during feeding, ensuring the stability of the feeding during peeling test.

[0010] In a preferred embodiment, the top of the wheel seat is movably installed with a lifting seat through a telescopic rod. The inside of the wheel seat is fixedly installed with a tension spring connected to the lifting seat. The front side of the lifting seat is rotatably installed with a top unidirectional wheel.

[0011] In practical application, the lifting seat is movably installed on the top of the wheel seat, and is elastically pulled down by the tension spring. When the lifting seat is elastically pulled down, the top one-way wheel and the bottom one-way wheel rotatably installed on the front of the lifting seat abut against each other. The abutment of the bottom one-way wheel and the top one-way wheel can clamp the carrier tape. The clamping of the carrier tape in the test area ensures the path of the carrier tape during the stripping test, avoids the inclination of the path of the carrier tape during the test, and affects the test result. The pre-clamping of the carrier tape in the test area facilitates the workers to install the two connecting ends of the carrier tape in the bottom clamping plate and the top clamping plate, so that the carrier tape can be supported and placed before the test, and the convenience of the workers during the installation and connection of the carrier tape during the test is improved. Meanwhile, the bottom one-way wheel and the top one-way wheel are both one-way rotating structures, so that the carrier tape cannot slide between the two one-way wheels, and the normal stripping and stretching test of the structure on the carrier tape is not affected.

[0012] In a preferred scheme, a guide plate is fixedly installed on one side of the wheel seat, and a plurality of groups of rollers are rotatably installed in the guide plate.

[0013] The guide plate can assist in supporting the carrier tape area to be tested, so that the pressure of the carrier tape during the stripping test is reduced, the accuracy of the stripping test of the structure on the carrier tape is improved, and the error is reduced. The rollers can roll and support the carrier tape when it moves on the guide plate, so that the surface of the carrier tape is not scratched when it moves on the guide plate, and the tension of the carrier tape when it moves on the guide plate is reduced.

[0014] As can be seen from the above, the carrier tape stripping force test structure for a pressure sensor comprises a test mechanism and an auxiliary mechanism assembled on one side of the test mechanism. The test mechanism comprises a test slide rail, a base fixedly installed on the bottom of the test slide rail, a bottom clamping plate fixedly installed on the top of the base, a test plate slidably installed on the front of the test slide rail, a pressure probe fixedly installed on the front of the inside of the test plate through a fixing seat, a test frame cooperatively used with the pressure probe, and a top clamping plate cooperatively used with the bottom clamping plate and fixedly installed on the bottom of the test frame.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. The components of the embodiments of the present application described and indicated in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0022] The present invention discloses a carrier strip peel force testing structure for pressure sensors, which is mainly used in practical applications. Traditional testing structures do not have the function of providing auxiliary support for the carrier strip in the area to be peeled. Since the carrier strip has a certain weight, it may twist or entangle when it is naturally hanging down. The twisting and entanglement of the hanging down will have a certain impact on the data when the carrier strip is peeled. This not only reduces the accuracy of the structure when peeling the carrier strip, but may also lead to poor stability and low testing efficiency when peeling the structure.

[0023] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A carrier strip peel force testing structure for a pressure sensor includes a testing mechanism 1 and an auxiliary mechanism 2 mounted on one side of the testing mechanism 1. The testing mechanism 1 includes a testing slide rail 101, a base 3 fixedly mounted on the bottom of the testing slide rail 101, a bottom clamping plate 301 fixedly mounted on the front side of the top of the base 3, a testing plate 102 slidably mounted on the front side of the testing slide rail 101, a pressure probe 404 fixedly mounted on the front side of the inside of the testing plate 102 via a fixing seat 403, a testing frame 4 for use with the pressure probe 404 is sleeved on the outside of the testing plate 102, and a top clamping plate 401 for use with the bottom clamping plate 301 is fixedly mounted on the bottom of the testing frame 4. The auxiliary mechanism 2 includes an auxiliary slide rail 201 mounted on one side of the testing slide rail 101, an auxiliary plate 202 slidably mounted on the front side of the auxiliary slide rail 201, a wheel seat 602 fixedly mounted on the front side of the auxiliary plate 202, and a bottom one-way wheel 6 rotatably mounted on the front side of the wheel seat 602.

[0024] Two sets of sliding plates 103 are fixedly installed on the outer wall of the front side of the test plate 102. The inner wall of the test frame 4 is provided with a sliding groove 405 that works with the sliding plate 103. A lifting rod 402 is fixedly installed on the top of the test frame 4. When the test frame 4 is assembled outside the test plate 102, the sliding groove 405 will fit on the outer wall of the sliding plate 103. Thus, the test frame 4 can be slidably installed during assembly through the sliding groove 405 and the sliding plate 103. It can also limit the front and rear movement of the test frame 4 during operation, so that the test frame 4 can only slide up and down outside the test plate 102, ensuring the stability of the test frame 4 during the peel test operation. The lifting rod 402 facilitates the operation of lifting the test frame 4 by the staff. Lifting the test frame 4 facilitates the maintenance of the pressure probe 404 by the staff.

[0025] In specific use, one side of the bottom clamping plate 301 and the top clamping plate 401 is screw-mounted to extend to the locking rod inside, and when the locking rod rotates clockwise, one end can abut against the inner wall of the bottom clamping plate 301 and the top clamping plate 401. The abutment of one end of the locking rod against the inner wall of the bottom clamping plate 301 and the top clamping plate 401 can fix the carrier tape inside, so that the carrier tape can be quickly fixed for testing, and the work efficiency of the staff for carrier tape installation testing is improved.

[0026] Wherein, the wheel seat 602 is fixedly installed with a guide plate 5 on one side, and a plurality of groups of rollers 501 are rotatably installed in the guide plate 5 at equal distances. The guide plate 5 can assist in supporting the carrier tape area waiting for testing, so as to avoid the carrier tape from increasing the pressure during the structural peeling test due to natural falling, improve the accuracy of the carrier tape peeling test, reduce the error, and the rollers 501 can roll and support the carrier tape when moving in the guide plate 5, so as to avoid the surface of the carrier tape from being scratched when moving in the guide plate 5, and also reduce the tension of the carrier tape when moving in the guide plate 5.

[0027] Specifically, when the carrier tape is subjected to the stripping test, the two connecting ends of the carrier tape test are respectively installed in the bottom clamping plate 301 and the top clamping plate 401, the test slide rail 101 lifts the test frame 4 through the test plate 102, the test frame 4 can cooperate with the top clamping plate 401 to test the carrier tape, the pressure probe 404 supports the test frame 4, so that the pressure probe 404 can detect the pressure when the test frame 4 strips the carrier tape, and the pressure probe 404 is connected with the external display, so that the connected display can display the data detected by the pressure probe 404, and the worker can know the stripping test value of the carrier tape according to the data detected by the pressure probe 404. The fixing seat 403 can fix the pressure probe 404 during operation, so as to ensure the stability of the pressure probe 404 during operation, and the fixing seat 403 can be disassembled to facilitate the worker to replace the pressure probe 404 according to the actual test requirement. The auxiliary slide rail 201 is installed on one side of the test slide rail 101, the front surface of the auxiliary slide rail 201 is fixedly installed with the wheel seat 602 through the auxiliary plate 202, the bottom one-way wheel 6 is rotatably installed on the front surface of the wheel seat 602, and the bottom one-way wheel 6 and the guide plate 5 can support the area where the carrier tape waits to be tested. Through the support of the bottom one-way wheel 6 and the guide plate 5, the distortion and deformation of the carrier tape when it naturally falls vertically can be avoided, so as to ensure the stability and accuracy of the structure for the carrier tape stripping test. At the same time, the bottom one-way wheel 6 can roll when the carrier tape moves, avoiding the surface scratch caused by friction when the carrier tape moves. For example, when the carrier tape is subjected to the stripping test, the bottom one-way wheel 6 supports the area where the carrier tape waits to be tested, and through the auxiliary support of the carrier tape, the distortion, deformation and even winding of the carrier tape during the natural falling process can be avoided. When the carrier tape is subjected to the stripping test, the distortion and deformation of the carrier tape will increase the pressure during the stripping and stretching, thereby affecting the data during the stripping test, and the worker needs to manually adjust or manually assist the support, which reduces the stability of the test structure during operation.

[0028] In the specific use process of the present application, the bottom one-way wheel 6 can support the area where the carrier tape waits to be tested, so as to avoid the distortion, deformation and winding of the carrier tape when it naturally falls vertically, thereby improving the accuracy of the structure during the carrier tape test, and also improving the stability of the structure during operation, avoiding the need for manual adjustment or manual assistance of the worker, and ensuring the efficiency of the test structure.

[0029] Reference Figure 3 and Figure 5In a preferred implementation, the top of the wheel seat 602 is movably mounted with a lifting seat 603 through a telescopic rod, the inside of the wheel seat 602 is fixedly mounted with a tension spring 604 connected with the lifting seat 603, the front of the lifting seat 603 is rotatably mounted with a top one-way wheel 601, the lifting seat 603 is movably mounted on the top of the wheel seat 602 and is elastically pulled down by the tension spring 604, when the lifting seat 603 is elastically lowered, the top one-way wheel 601 and the bottom one-way wheel 6 rotatably mounted on the front of the lifting seat 603 are in contact, the contact between the bottom one-way wheel 6 and the top one-way wheel 601 can clamp the test area of the carrier tape, clamping the test area of the carrier tape ensures the path of the carrier tape during the stripping test, avoids the inclination of the carrier tape during the test, and the pre-clamping of the test area of the carrier tape facilitates the workers to install the two connecting ends in the bottom clamping plate 301 and the top clamping plate 401, so that the carrier tape can be supported and placed before the connection operation during the test, improving the convenience of the workers during the installation and connection of the carrier tape during the test, and the bottom one-way wheel 6 and the top one-way wheel 601 are both one-way rotating structures, so that the carrier tape cannot slip between them, and the normal stripping and stretching test of the structure on the carrier tape is not affected.

[0030] The top of the lifting seat 603 is fixedly mounted with an operating rod 605, which facilitates the workers to lift the lifting seat 603 and the top one-way wheel 601, and facilitates the workers to place the carrier tape on the top of the bottom one-way wheel 6 by lifting the top one-way wheel 601, and the elastic lowering of the lifting seat 603 and the top one-way wheel 601 by the tension spring 604 can press the carrier tape on the bottom one-way wheel 6 when the workers release their hands.

[0031] Specifically, the four corners of the bottom of the base 3 are threadedly mounted with threaded rods 302, and the bottom of each threaded rod 302 is rotatably mounted with a foot plate 303, and the threaded rods 302 and the foot plates 303 can support the bottom of the base 3, and the height of the foot plates 303 can be adjusted by rotating the threaded rods 302 clockwise and counterclockwise, and the stability of the stripping structure when placed on uneven ground can be ensured by adjusting the height of the foot plates 303 at each corner.

[0032] For example, when the structure is testing the carrier tape, the carrier tape may be inclined when feeding, the angle of the structure testing the carrier tape may change when the carrier tape is inclined when feeding, the tension may be reduced when the carrier tape is at an angle, and the data of the structure testing the carrier tape may be deviated.

[0033] And among them, the scheme adopts: through the bottom unidirectional wheel 6 and the top unidirectional wheel 601, the path of the carrier tape feeding is limited, which avoids the inclination of the path of the carrier tape stripping feeding, ensures the parallel state of the two sides of the carrier tape stripping, and improves the precision of the carrier tape stripping test.

[0034] Working principle: when testing the carrier tape, the bottom unidirectional wheel 6 and the top unidirectional wheel 601 can support and clamp the test area of the carrier tape, which facilitates the workers to quickly connect the connecting end of the carrier tape with the bottom clamp plate 301 and the top clamp plate 401, the test slide rail 101 can lift the test frame 4 to strip the carrier tape, the pressure probe 404 can detect the pressure when the test frame 4 strips the carrier tape, the bottom unidirectional wheel 6 and the guide plate 5 can support the test area of the carrier tape, which avoids the twisting and winding of the carrier tape during the test, and the top unidirectional wheel 601 can guide and limit the feeding path of the carrier tape stripping test, which avoids the inclination of the carrier tape during the stripping test, and ensures the stability of the feeding during the carrier tape stripping test.
