Description

Technical Field

[0001] This utility model relates to the field of separation testing technology, and in particular to a double-layer sheet push-out separation tester. Background Technology

[0002] The double-layer sheet consists of a substrate and a patch. The substrate has through-holes, and the patch is attached to the substrate, covering the through-holes. After the double-layer sheet is produced, the separation force between the patch and the substrate needs to be tested to ensure that the patch's required tear-off force from the substrate is qualified, thus ensuring that the double-layer sheet meets the user's needs. The applicant has filed numerous patents for peel force testing, such as: a constant temperature and humidity peel force testing machine (application number 201720826200.1), a 90-degree tape peeling fixture (application number 201621134970.1), and a peel strength testing machine (application number 201720774333.9), etc. However, the structure of these patent documents cannot achieve a push-pull separation test for the double-layer sheet. Therefore, a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a double-layer sheet pushing and separating tester.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A double-layer sheet push-separation tester includes a machine base, a gantry frame mounted on the top surface of the machine base, a push-drive mechanism mounted on and within the machine base, a force sensor mounted on the drive end of the push-drive mechanism, a push rod mounted on the input end of the force sensor, a push pin disposed on the top of the push rod, a Y-axis adjustment module mounted on two opposite side plates of the gantry frame, an X-axis adjustment module mounted on the adjustment end of the Y-axis adjustment module, and an adjustment end mounted on the X-axis adjustment module. The platform is located above the push pin, and the shooting mechanism is installed in the middle of the lower side of the top plate of the gantry. The shooting mechanism is located above the platform, and the force sensor is located above the top surface of the machine. A push hole is opened in the middle of the platform, and upper limit blocks are set on both sides of the platform. A slot is formed between the upper limit block and the top surface of the platform. A connection hole communicating with the slot is opened on the top surface of the upper limit block. A locking fastener is detachably installed in the connection hole. The locking fastener is used to lock the end of the substrate of the double-layer sheet in the slot.

[0006] Furthermore, the connecting hole is a threaded hole, the locking device is a locking bolt, and the stud of the locking bolt is threadedly connected to the threaded hole.

[0007] Furthermore, a connecting sleeve is installed at the bottom end of the push rod, and the connecting sleeve is fitted onto the output end of the force sensor.

[0008] Furthermore, a through hole is provided on the top surface of the machine tool, and the pushing end of the pushing drive mechanism passes through the through hole and is connected to the force sensor, which is located above the top surface of the machine tool.

[0009] Furthermore, the Y-axis adjustment module includes two Y-axis adjustment components respectively installed on the two side plates of the gantry. The Y-axis adjustment component includes two fixed seats fixedly connected to the front and rear ends of the two side plates of the gantry, a Y-axis guide rod installed between the two fixed seats, a Y-axis adjustment block slidably sleeved on the Y-axis guide rod and slidably connected to the side plates of the gantry, and a Y-axis locking member set on the Y-axis adjustment block and used to lock the Y-axis adjustment block on the Y-axis guide rod. The two ends of the X-axis adjustment module are respectively installed on the Y-axis adjustment blocks of the two Y-axis adjustment components.

[0010] Furthermore, the X-axis adjustment module includes two adjustment seats respectively mounted on the Y-axis adjustment blocks of the two Y-axis adjustment components, two X-axis guide rods spaced apart and parallel between the two adjustment seats, two sets of X-axis adjustment blocks respectively slidably sleeved outside the two X-axis guide rods, and an X-axis locking member disposed on at least one set of X-axis adjustment blocks and used to lock the X-axis adjustment blocks to the X-axis guide rods. The stage is mounted on the two sets of X-axis adjustment blocks, and the push pin is located between the two X-axis guide rods.

[0011] Furthermore, the shooting mechanism includes a lifting and adjusting module installed in the middle of the lower side of the top plate of the gantry and a CCD camera installed in the adjusting end of the lifting and adjusting module, with the CCD camera located above the stage.

[0012] The beneficial effects of this utility model are as follows: In practical applications, after aligning the two ends of the double-layer sheet with the two slots respectively, the double-layer sheet is inserted into the platform along the side of the slot. Then, the locking fastener locks the substrate end of the double-layer sheet in the slot to lock the double-layer sheet on the platform. The upper limit block abuts against the top surface of the substrate of the double-layer sheet. Then, the shooting mechanism performs visual positioning on the patch on the double-layer sheet carried by the platform. According to the visual positioning result of the shooting mechanism, the position of the platform is adjusted by the Y-axis adjustment module and the X-axis adjustment module working together, thereby adjusting the relative position of the double-layer sheet and the push pin on the platform, so that the push pin can be aligned with the center of the through hole on the substrate. Then, the push drive mechanism drives the force sensor to move upward along with the push rod and the push pin, so that the push pin is inserted into the through hole and pushes the patch upward until the patch separates from the substrate (patch peels off or is torn from the substrate). During this process, the force sensor will test the separation force of the patch and the substrate to test the maximum force of the patch separating from the substrate. In addition, during the process of the push pin pushing the patch, the imaging mechanism records the real-time separation of the patch from the substrate. This recording can also be played back on an external display screen, allowing operators to monitor the situation in real time. This invention can test the separation force of the patch and substrate in double-layer sheets, and the imaging mechanism enables visual positioning and real-time recording, ensuring the positional accuracy of the push pin pushing the patch, which is beneficial for operators to monitor the separation test in real time.

[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] like Figures 1 to 3 As shown, this utility model provides a double-layer sheet push-separation tester, which includes a machine base 1, a gantry frame 2 mounted on the top surface of the machine base 1, a push-drive mechanism 3 mounted on and located within the machine base 1, a force sensor 4 mounted on the drive end of the push-drive mechanism 3, a push rod 5 mounted on the input end of the force sensor 4, a push pin 6 located on the top of the push rod 5, a Y-axis adjustment module 7 mounted on two opposite side plates of the gantry frame 2, an X-axis adjustment module 8 mounted on the adjustment end of the Y-axis adjustment module 7, and an adjustment end of the X-axis adjustment module 8 located above the push pin 6. The platform 9 and the shooting mechanism 10 are installed on the lower side of the top plate of the gantry 2. The shooting mechanism 10 is located above the platform 9. The force sensor 4 is located above the top surface of the machine base 1. A push hole 11 is opened in the middle of the platform 9. Upper limit blocks 12 are provided on both sides of the platform 9. A slot 13 is formed between the upper limit block 12 and the top surface of the platform 9. A connection hole communicating with the slot 13 is opened on the top surface of the upper limit block 12. A locking fastener 14 is detachably provided in the connection hole. The locking fastener 14 is used to lock the end of the substrate of the double-layer sheet 28 in the slot 13. The push pin 6 is coaxially arranged with the push rod 5. Specifically, the double-layer sheet 28 includes a substrate and a patch attached to the substrate. The substrate has a through hole, and the patch covers the through hole. The area of ​​the patch is smaller than the area of ​​the substrate.

[0020] In practical applications, after aligning both ends of the double-layer sheet 28 with the two slots 13 respectively, the double-layer sheet 28 is inserted laterally into the stage 9 along the slots 13. Then, the fastener 14 locks the substrate end of the double-layer sheet 28 into the slots 13, thus securing the double-layer sheet 28 onto the stage 9. The upper limit block 12 abuts against the top surface of the substrate of the double-layer sheet 28. Then, the imaging mechanism 10 performs visual positioning on the patch on the double-layer sheet 28 supported by the stage 9. Based on the visual positioning result of the imaging mechanism 10, the Y-axis adjustment module 7 and the X-axis adjustment module 7 are used for adjustment. The entire module 8 works in concert to adjust the position of the platform 9, thereby adjusting the relative position of the double-layer sheet 28 and the push pin 6 on the platform 9. This allows the push pin 6 to align with the center of the through hole on the substrate. Then, the push-drive mechanism 3 drives the force sensor 4, along with the push rod 5 and the push pin 6, to move upwards, causing the push pin 6 to insert into the through hole and push the patch upwards until the patch separates from the substrate (patch peels off or is torn from the substrate). During this process, the force sensor 4 tests the separation force of the patch from the substrate to determine the maximum force at which the patch separates from the substrate. Additionally, during the process of the push pin 6 pushing the patch, the imaging mechanism 10 captures images to record the real-time separation process of the patch from the substrate. This recording can also be played back on an external display screen, allowing operators to monitor the situation in real time. This invention enables the testing of the separation force between the patch and the substrate of the double-layer sheet 28. Furthermore, the imaging mechanism 10 provides visual positioning and real-time imaging, ensuring the positional accuracy of the push pin 6 pushing the patch, and allowing operators to monitor the separation test in real time.

[0021] In this embodiment, the connecting hole is a threaded hole, and the locking fastener 14 is a locking bolt, with the stud of the locking bolt threadedly connected to the threaded hole. This structural design enables a detachable connection between the connecting hole and the locking fastener 14, and also facilitates the locking fastener 14 in locking the substrate of the double-layer sheet 28 within the slot 13.

[0022] In this embodiment, a connecting sleeve 15 is installed at the bottom end of the push rod 5, and the connecting sleeve 15 is fitted onto the output end of the force sensor 4. This structural design facilitates the connection and disassembly of the push rod 5 and the force sensor 4.

[0023] In this embodiment, a through hole 16 is provided on the top surface of the machine base 1. The pushing end of the pushing drive mechanism 3 passes through the through hole 16 and is connected to the force sensor 4. The force sensor 4 is located above the top surface of the machine base 1. This structural design makes the structure of the pushing drive mechanism 3 and the machine base 1 compact, and facilitates the pushing drive mechanism 3 to drive the force sensor 4 and push rod to rise and fall.

[0024] In this embodiment, the Y-axis adjustment module 7 includes two Y-axis adjustment components 17 respectively installed on the two side plates of the gantry frame 2. The Y-axis adjustment component 17 includes two fixed seats 18 fixedly connected to the front and rear ends of the two side plates of the gantry frame 2, a Y-axis guide rod 19 installed between the two fixed seats 18, a Y-axis adjustment block 20 slidably sleeved on the Y-axis guide rod 19 and slidably connected to the side plates of the gantry frame 2, and a Y-axis locking member 21 disposed on the Y-axis adjustment block 20 and used to lock the Y-axis adjustment block 20 on the Y-axis guide rod 19. The two ends of the X-axis adjustment module 8 are respectively installed on the Y-axis adjustment blocks 20 of the two Y-axis adjustment components 17. Specifically, the Y-axis locking member 21 can be a locking bolt.

[0025] In practical applications, the Y-axis locking component 21 releases its locking of the Y-axis adjusting block 20, allowing the Y-axis adjusting block 20 to move along the Y-axis guide rod 19 to adjust the position of the X-axis adjusting module 8 on the Y-axis, thereby adjusting the position of the stage 9 on the Y-axis. After adjustment, simply tighten the Y-axis locking component 21 to lock the Y-axis adjusting block 20 onto the Y-axis guide rod 19, thus fixing the position of the stage 9 on the Y-axis.

[0026] In this embodiment, the X-axis adjustment module 8 includes two adjustment seats 22 respectively mounted on the Y-axis adjustment blocks 20 of the two Y-axis adjustment components 17, two X-axis guide rods 23 spaced apart and parallel between the two adjustment seats 22, two sets of X-axis adjustment blocks 24 respectively slidably sleeved on the two X-axis guide rods 23, and an X-axis locking member 25 disposed on at least one set of X-axis adjustment blocks 24 and used to lock the X-axis adjustment blocks 24 to the X-axis guide rods 23. The platform 9 is mounted on the two sets of X-axis adjustment blocks 24, and the push pin 6 is located between the two X-axis guide rods 23. Specifically, the X-axis locking member 25 can be a locking bolt.

[0027] In practical applications, the X-axis locking member 25 releases the locking of the X-axis adjusting block 24, allowing the X-axis adjusting block 24 to drive the stage 9 to adjust its position on the X-axis along the X-axis guide rod 23, thereby adjusting the position of the stage 9 on the X-axis. After adjustment, simply tighten the X-axis locking member 25 to lock the X-axis adjusting block 24 onto the X-axis guide rod 23, thus fixing the position of the stage 9 on the X-axis.

[0028] In this embodiment, the shooting mechanism 10 includes a lifting and adjusting module 26 mounted on the lower side of the top plate of the gantry 2 and a CCD camera 27 mounted on the adjusting end of the lifting and adjusting module 26. The CCD camera 27 is located above the stage 9. Specifically, the lifting and adjusting module 26 can adopt an existing lifting drive mechanism, which will not be described in detail here. In practical applications, the lifting and adjusting module 26 drives the CCD camera 27 to rise and fall to adjust the height position of the CCD camera 27, thereby adjusting the focal length of the CCD camera 27.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
