Description

Technical Field

[0001] This utility model relates to the field of micro-drop testing machines, and in particular to a micro-drop testing machine. Background Technology

[0002] In daily life and transportation, electronic products may be subjected to various external impacts, such as slipping or accidental drops. These impacts may damage the appearance, function, and performance of the product, or even cause it to fail. Therefore, in order to ensure the quality and reliability of electronic products, it is necessary to conduct drop impact tests on them through a micro-drop tester during the production of electronic products to test their performance.

[0003] In existing technologies, the product to be tested is mainly placed at a certain height, released, and dropped to test it. However, existing drop testing machines have certain limitations in use. They are single-function, cannot be adjusted and corrected at any time, and the drop height cannot reach the ideal state, making them inconvenient to use. Moreover, some existing drop testing structures are exposed, posing a potential danger if the operator makes a mistake or other accident occurs and touches the equipment. Furthermore, external objects or impurities entering the test area can interfere with the test process or damage the test sample, affecting the accuracy and reliability of the test results and the test efficiency. Therefore, a micro drop testing machine is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as limited functionality, inability to adjust and correct height at any time, failure to achieve ideal drop heights, inconvenience in use, and the fact that some existing drop test structures are exposed, posing potential dangers during operation due to operator errors or other unexpected events. Furthermore, the entry of external objects or impurities into the test area can interfere with the test process or damage the test samples, affecting the accuracy and reliability of the test results and the test efficiency. Therefore, this invention proposes a micro-drop test machine to solve the above problems.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A micro-drop test machine, comprising:

[0007] The workbench has a protective cover fixedly installed on its top, and the outer wall of the protective cover is rotatably connected to a door via a hinge. Multiple sets of doors are provided. A support rod is fixedly installed on the top of the workbench. A height scale is fixedly installed on the outer wall of the support rod, and a servo motor shaft is installed on the inner wall of the support rod. A crossbeam is movably connected to the outer wall of the servo motor shaft. A guide rod is movably engaged at the top of the crossbeam. A cylinder is fixedly connected to the bottom of the guide rod via a support frame. Clamping frames are fixedly installed on both sides of the cylinder's output end, and the product to be tested is clamped between two sets of clamping frames.

[0008] Preferably, the inner wall of the support rod is fixedly provided with a guide post, and multiple sets of guide posts are provided, and the crossbeam is movably inserted into the outer wall of the guide post.

[0009] Preferably, a panel is fixedly provided on the top of the workbench, and the panel is located below the clamping frame.

[0010] Preferably, the outer wall of the workbench is provided with heat dissipation holes, and a control panel is fixedly installed on the outer wall of the workbench.

[0011] Preferably, multiple sets of guide rods, cylinders, and clamping frames are provided and symmetrically distributed on both sides of the crossbeam, and the bottom of the worktable is provided with rollers for easy movement.

[0012] Preferably, the bottom of the workbench is provided with a groove, and a connecting shaft is rotatably connected to the inner wall of the groove. A connecting block is fixedly provided on the outer wall of the connecting shaft, and the top of the roller is rotatably connected to the bottom of the connecting block through a rotating shaft.

[0013] Preferably, one end of the connecting shaft extends outward through the worktable, and a rotating plate is fixedly provided at one end of the connecting shaft, with an adjusting plate fixedly provided on the outer wall of the rotating plate.

[0014] Preferably, a compression spring is fixedly provided on the inner wall of the rotating plate, and a positioning block is fixedly provided on the other end of the compression spring. A fixing ring block is fixedly provided on the outer wall of the worktable. A first positioning port is opened on the inner wall of the fixing ring block, and the positioning block is connected and locked in the first positioning port. A baffle is fixedly provided on the outer wall of the positioning block through the rotating plate.

[0015] Preferably, the inner wall of the fixing ring block is provided with a second positioning port.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, by setting the connection relationship between the workbench, protective cover, box door, servo motor shaft, crossbeam, cylinder, and clamping frame, the product to be tested is placed between two sets of clamping frames inside the protective cover by opening the box door, and then the box door is closed. This effectively shields the high-speed moving parts and potentially dangerous areas during operation, preventing operators from being injured due to accidental contact or other unforeseen circumstances, thus improving safety. It also prevents external objects or impurities from entering the test area, interfering with the test process or damaging the test samples, thereby ensuring the accuracy and reliability of the test results. The cylinder is activated via the control panel to clamp the product to be tested between the two sets of clamping frames, and... The servo motor drives the servo motor shaft to rotate, thereby adjusting the position and height of the crossbeam. This, in turn, adjusts the position and height of the product clamped by the two sets of clamps, thus adjusting the drop height of the product. This simulates drop scenarios from different heights, meeting the testing needs of various products. The drop height of the test piece can be determined by the value on the height scale corresponding to the crossbeam. Once the product to be tested moves to the set height, the cylinder is activated, causing the two sets of clamps to move to both sides, loosening the product and allowing it to fall downwards under gravity for testing. Furthermore, by setting multiple sets of guide rods, cylinders, and clamps, multiple sets of products can be tested simultaneously, further improving testing efficiency.

[0018] 2. In this utility model, by setting the connection relationship between the roller, connecting block, connecting shaft, and rotating plate, the roller is rolled by pushing the worktable, which drives the entire equipment to move. The user pushes the baffle towards the adjustment plate, causing the positioning block to move out of the second positioning port. At this time, rotating the connecting shaft upward causes the roller to move upward and retract into the groove, so that the bottom of the worktable is in contact with the ground, increasing the friction between the equipment and the ground and further improving the stability of the equipment. Rotating the connecting shaft downward causes the roller to move downward and move out of the groove, so that the roller contacts the ground, reducing the friction between the roller and the ground, facilitating the movement of the equipment, making it easy to adjust and use as needed, and improving the flexibility of use.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example: This example provides a micro-drop testing machine, see [link to example]. Figure 1-6 Specifically, including:

[0030] Workbench 1, with a protective cover 101 fixedly installed on its top. The protective cover 101, installed over the testing area, effectively shields high-speed moving parts and potentially hazardous areas during operation, preventing operator injury due to accidental contact or other unforeseen circumstances, thus improving safety. It also prevents external objects or impurities from entering the testing area, interfering with the testing process or damaging the test samples, thereby ensuring the accuracy and reliability of the test results. The outer wall of the protective cover 101 is hinged to a door 102, with multiple doors 102. A sensor is installed inside the protective cover 101; when the door 102 of the protective cover 101 is opened... The equipment stops operating, further improving safety. A support rod 2 is fixedly installed on the top of the workbench 1. A height scale is fixedly installed on the outer wall of the support rod 2, and a servo motor shaft 201 is installed on the inner wall of the support rod 2. A crossbeam 203 is movably connected to the outer wall of the servo motor shaft 201. A guide rod 204 is movably latched on the top of the crossbeam 203. A cylinder 205 is fixedly connected to the bottom of the guide rod 204 through a support frame. Clamping frames 206 are fixedly installed on both sides of the output end of the cylinder 205. The product to be tested is clamped between the two sets of clamping frames 206. In use, the product to be tested is placed between the two sets of clamping frames 206, and the cylinder 205 is started to drive the two sets of clamping frames 206. The servo motor moves towards the center, clamping the product to be tested between the two sets of clamping frames 206. When the servo motor starts and drives the servo motor shaft 201 to rotate clockwise, the clockwise rotating servo motor shaft 201 drives the crossbeam 203 to move upward. The upward-moving crossbeam 203 drives the guide rod 204 to move upward, which in turn drives the clamping frame 206 to move upward, causing the product clamped by the two sets of clamping frames 206 to move upward. When the servo motor starts and drives the servo motor shaft 201 to rotate counterclockwise, the counterclockwise rotating servo motor shaft 201 drives the crossbeam 203 to move downward. The downward-moving crossbeam 203 drives the product to move upward. The movable clamp 206 moves downward, causing the product clamped by the two sets of clamps 206 to move downward, thus adjusting the drop height of the product to simulate drop conditions at different heights, thereby meeting the testing needs of various products. The drop height of the test piece can be determined by the value on the height scale corresponding to the crossbeam 203. When the product to be tested moves to the set height, the cylinder 205 is activated to drive the two sets of clamps 206 to move to both sides, loosening the product and causing it to fall downward under gravity for testing. Furthermore, by setting multiple sets of guide rods 204, cylinders 205, and clamps 206, multiple sets of products can be tested simultaneously, further improving the testing efficiency.

[0031] The inner wall of the support rod 2 is fixedly provided with guide posts 202, and multiple sets of guide posts 202 are provided. The crossbeam 203 is movably inserted into the outer wall of the guide posts 202. The crossbeam 203 slides along the outer wall of the guide posts 202, thereby restricting the movement path of the crossbeam 203 and further improving its stability.

[0032] A panel 207 is fixedly installed on the top of the workbench 1, and the panel 207 is located below the clamping frame 206 to receive the falling products.

[0033] The outer wall of the workbench 1 is provided with heat dissipation holes 103 to dissipate heat from the internal equipment of the workbench 1, and a control screen 104 is fixedly installed on the outer wall of the workbench 1 to control the operation of the equipment components.

[0034] Multiple sets of guide rods 204, cylinders 205, and clamping frames 206 are provided and symmetrically distributed on both sides of the crossbeam 203. By setting multiple sets of guide rods 204, cylinders 205, and clamping frames 206, multiple sets of products can be tested simultaneously, further improving the testing efficiency. The bottom of the workbench 1 is equipped with rollers 3 for easy movement. By pushing the workbench 1, the rollers 3 roll, thereby moving the entire equipment.

[0035] The bottom of the workbench 1 has a groove, and a connecting shaft 302 is rotatably connected to the inner wall of the groove. A connecting block 301 is fixedly installed on the outer wall of the connecting shaft 302, and the top of the roller 3 is rotatably connected to the bottom of the connecting block 301 through a rotating shaft. In use, by rotating the connecting shaft 302 upward, the connecting block 301 is driven to rotate upward, causing the roller 3 to move upward and retract into the groove, so that the bottom of the workbench 1 is in contact with the ground, increasing the friction between the equipment and the ground and further improving the stability of the equipment. By rotating the connecting shaft 302 downward, the roller 3 is driven to move downward and move out of the groove, so that the roller 3 contacts the ground, reducing the friction between the roller and the ground, facilitating the movement of the equipment, making it easy to adjust and use as needed, and improving the flexibility of use.

[0036] One end of the connecting shaft 302 extends outward through the workbench 1, and a rotating plate 303 is fixedly installed at one end of the connecting shaft 302. An adjusting plate 307 is fixedly installed on the outer wall of the rotating plate 303. The user holds the adjusting plate 307 and applies force to rotate the adjusting plate 307, which causes the rotating plate 303 to rotate, thereby causing the connecting block 301 and the roller 3 to rotate, making it easy to adjust the position of the roller 3.

[0037] A compression spring 304 is fixedly installed on the inner wall of the rotating plate 303, and a positioning block 305 is fixedly installed on the other end of the compression spring 304. A fixing ring block 308 is fixedly installed on the outer wall of the worktable 1. A first positioning port 309 is opened on the inner wall of the fixing ring block 308, and the positioning block 305 is connected and locked in the first positioning port 309. The outer wall of the positioning block 305 extends outward through the rotating plate 303 and is fixedly installed with a baffle 306. In use, the user pushes the baffle 306 in the direction of the adjusting plate 307, so that the moving baffle 306 drives the positioning block 305 to move, so that the positioning block 305 moves out of the first positioning port 309. At this time, the rotating plate 303 is in an active state. By rotating the rotating plate 303 downward, the roller 3 is driven to rotate downward, which facilitates the adjustment of the use position of the roller 3.

[0038] The inner wall of the fixed ring block 308 is provided with a second positioning port 310. When the roller 3 rotates downward to the vertical position, the positioning block 305 is aligned with the second positioning port 310. By releasing the push baffle 306, the pushing force of the compression spring 304 pushes the positioning block 305, so that the positioning block 305 is inserted into and locked in the second positioning port 310, thereby fixing the rotating plate 303 and fixing the position of the roller 3. This prevents the connecting block 301 from rotating randomly during movement, which would affect the stability of the application.

[0039] Specifically, the working principle and operation method of this utility model are as follows:

[0040] In use, by opening the chamber door 102 and placing the product to be tested between the two sets of clamping frames 206 inside the protective cover 101, and then closing the chamber door 102, the high-speed moving parts and potentially dangerous areas are effectively shielded during operation, preventing operator injury due to accidental contact or other unforeseen circumstances, thus improving safety. It also prevents external objects or impurities from entering the test area, interfering with the test process or damaging the test samples, thereby ensuring the accuracy and reliability of the test results. The operation of the equipment components is controlled via the touchscreen of the control panel 104. The cylinder 205 is activated, moving the two sets of clamping frames 206 towards the center, clamping the product to be tested between them. When the servo motor is activated, it drives the servo motor shaft 201 to rotate clockwise, causing the clockwise rotating servo motor shaft 201 to move the crossbeam 203 upwards. The upward-moving crossbeam 203... 03 drives the guide rod 204 to move upward, which in turn drives the clamping frame 206 to move upward, causing the product clamped by the two clamping frames 206 to move upward. When the servo motor starts and drives the servo motor shaft 201 to rotate counterclockwise, the counterclockwise rotating servo motor shaft 201 drives the crossbeam 203 to move downward. The downward moving crossbeam 203 drives the clamping frame 206 to move downward, causing the product clamped by the two clamping frames 206 to move downward. This allows for adjustment of the product's drop height, simulating drop conditions at different heights to meet the testing needs of various products. The drop height of the test piece can be determined by the value on the height scale corresponding to the crossbeam 203. When the product to be tested moves to the set height, the cylinder 205 starts and drives the two clamping frames 206 to move to both sides, loosening the product and causing it to fall downward under gravity for testing.

[0041] In use, pushing the worktable 1 causes the rollers 3 to roll, moving the entire device. The user can also push the baffle 306 towards the adjusting plate 307, causing the baffle 306 to move the positioning block 305 out of the second positioning port 310. At this time, the rotating plate 303 is in an active state. Rotating the connecting shaft 302 upwards causes the connecting block 301 to rotate upwards, moving the rollers 3 upwards and retracting them into the groove, bringing the bottom of the worktable 1 into contact with the ground, increasing friction between the device and the ground, and further improving the device's stability. Rotating the connecting shaft 302 downwards causes the rollers 3 to move downwards out of the groove, bringing them into contact with the ground, reducing friction, facilitating device movement, and allowing for adjustment as needed, thus improving operational flexibility.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
