Description

Technical Field

[0001] This utility model relates to the field of fracture force measurement technology, specifically to a fracture force measurement device for epoxy molding compound. Background Technology

[0002] EMC pellets are products of a specified diameter and weight formed by physically pressing powder. During production, transportation, and storage, they are subject to collisions and vibrations, which can cause breakage or damage during customer use, affecting customer experience. Therefore, it is necessary to assess the maximum destructive force that EMC pellets can withstand upon fracture. Existing measuring equipment often simply places the pellet on a testing platform and compresses it with pressure equipment to measure the maximum destructive force. This method often cannot test the periphery of the pellet, resulting in limited data. To address this, an epoxy molding compound fracture force measuring device is provided. Utility Model Content

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0019] Example: Please refer to Figure 1-2 This utility model provides a technical solution: an epoxy molding compound fracture force measuring device, including a measuring platform 1, a lifting frame 2, a control panel 3, and a sample clamping mechanism 4 mounted on the top of the measuring platform 1. The lifting frame 2 has a slide groove 202, a slider 203 is disposed within the slide groove 202, a connector 205 is mounted on the bottom of the slider 203, a pressure sensor 204 is installed between the connector 205 and the slider 203, a compression rod 206 is mounted on the bottom of the connector 205, a motor 201 is mounted on the top of the lifting frame 2, and the output shaft of the motor 201 is connected to a first lead screw 207 via a coupling. The slider 203 is threaded, and the bottom end of the first lead screw 207 is connected to the bearing fixed at the bottom of the slide groove 202. The motor 201 drives the first lead screw 207 to rotate. The first lead screw 207 rotates around the bearing, which allows the slider 203 to move in the slide groove 202. The slider 203 slowly descends, which drives the extrusion rod 206 to descend, thereby measuring the breaking force on the periphery of the cake. When the extrusion rod 206 extrudes the periphery of the cake, the pressure sensor 204 senses the pressure and transmits the pressure data to the control screen through the controller. When the cake breaks, the maximum pressure is recorded as the maximum breaking force.

[0020] like Figure 3-4As shown, a sample clamping mechanism 4 is provided on one side of the lifting frame 2. The sample clamping mechanism 4 includes a base 401, a second slide rod 411 is installed on the top of the base 401, a movable seat 403 is movably connected to the second slide rod 411, a clamping movable frame 405 is installed on the top of the movable seat 403, a first slide rod 408 is provided on both sides inside the clamping movable frame 405, a clamping moving block 407 is movably connected to the first slide rod 408, a clamping block 412 is installed at the bottom of the clamping moving block 407, a first screw 406 is threadedly connected to the top of the clamping movable frame 405, a screw fixing seat 409 is fixed to one end of the second slide rod 411, a second screw 410 is threadedly connected to the middle of the screw fixing seat 409, one end of the second screw 410 passes through the screw fixing seat 409 and is fixedly connected to the handwheel 402, and the other end of the second screw 410 is connected to the movable seat. 403 is connected by a movable mechanism; when different diameter cakes need to be installed, the distance between the clamp block 412 at the bottom of the clamp moving block 407 and the movable seat 403 is adjusted by rotating the first screw 406. Then, the cake is placed in the test piece placement slot 413. By rotating the first screw 406, the first screw 406 is pressed against the clamp moving block 407, causing the clamp moving block 407 to slide down along the first slide bar 408. The clamp block 412 at the bottom of the clamp moving block 407 is then pressed and fixed to the cake, thus fixing cakes of different diameters. After fixing the cake, the handwheel 402 is rotated to drive the second screw 410 to rotate. The rotation of the second screw 410 pushes the movable seat 403 to move, allowing the cake on the movable seat 403 to move directly below the extrusion rod 206, facilitating the measurement of the cake's breaking force.

[0021] The base 401 is bolted to the measuring table 1. The bottom of the base 401 has a special-shaped groove 404 that matches the second slide rod 411. The lead screw fixing seat 409 is welded to the base 401.

[0022] The first screw 406 is connected to the fixture moving block 407 by a bearing, and the other end of the second screw 410 is connected to the movable seat 403 by a bearing. The top of the movable seat 403 is provided with a test piece placement slot 413.

[0023] The lifting frame 2 is installed on the top of the measuring platform 1 by bolts. The connector 205 is fixedly connected to the slider 203 by bolts, and the extrusion rod 206 is fixedly connected to the connector 205 by bolts.

[0024] The control panel 3 is equipped with a control screen, which is electrically connected to a controller located inside the control panel 3. The controller is electrically connected to the motor 201 and the pressure sensor 204. The motor 201 is controlled to work by the touch buttons on the control panel and the controller. The pressure sensor 204 displays the detected pressure data on the control panel through the controller.

[0025] The movable seat 403 and the movable clamp frame 405 are fixedly connected by bolts, which facilitates disassembly later.

[0026] Working principle: An epoxy molding compound fracture force measuring device, when different diameter biscuits need to be installed, the distance between the clamp block 412 at the bottom of the clamp moving block 407 and the movable seat 403 is adjusted by rotating the first screw 406. Then, the biscuit is placed in the test piece placement slot 413. By rotating the first screw 406, the first screw 406 is pressed against the clamp moving block 407, causing the clamp moving block 407 to slide down along the first slide rod 408. The clamp block 412 at the bottom of the clamp moving block 407 is then pressed and fixed to the biscuit, thus fixing biscuits of different diameters. After fixing the biscuit, the handwheel 402 is rotated, causing the second screw 410 to rotate. The rotation of the second screw 410 pushes the movable seat 403 to move, allowing the biscuit on the movable seat 403 to move directly below the extrusion rod 206, facilitating the measurement of the biscuit's fracture force.

[0027] The motor 201 is controlled by the control panel on the control console 3. The motor 201 drives the first lead screw 207 to rotate. The first lead screw 207 rotates around the bearing, which causes the slider 203 to move in the groove 202. The slider 203 slowly descends, which drives the extrusion rod 206 to descend, thereby measuring the breaking force on the periphery of the cake. When the extrusion rod 206 extrudes the periphery of the cake, the pressure sensor 204 senses the pressure and transmits the pressure data to the control panel through the controller. When the cake breaks, the maximum pressure is recorded as the maximum breaking force.

[0028] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
