[0013] Preferably, the height precision adjustment device includes a vertical guide rail, a scale, a precision lead screw, and a stepper motor;

[0016] Preferably, a sample fixing base plate is provided on one side of the high-precision adjustment device, and a sample impact point is provided on the sample fixing base plate.

[0017] Preferably, it also includes a level; the level is mounted on one side of the orientation adjustment device.

[0018] Preferably, the steel ball has a diameter of 2 inches and a weight of 1.1 pounds.

[0019] This application has the following advantages:

[0020] In the embodiments of this application, compared with the prior art where "impact point positioning relies on manual visual inspection", this application provides a solution that "achieves collinearity of the slot center, the steel ball center, and the sample impact point through laser collimation positioning". Specifically, it includes a laser collimation positioning device, an electromagnetic release impact device, an orientation adjustment device, and a height precision adjustment device; one end of the orientation adjustment device is equipped with the electromagnetic release impact device, and the other end of the orientation adjustment device is equipped with the height precision adjustment device; one side of the electromagnetic release impact device is equipped with the laser collimation positioning device; the electromagnetic release impact device includes an electromagnet and a steel ball; the electromagnet has a slot that can accommodate the steel ball, and the steel ball is adsorbed in the slot; the laser beam projection path of the laser collimation positioning device is collinear with the center of the slot, the center of the steel ball, and the sample impact point in a vertical plane.

This improves the repeatability and accuracy of the test from both the positioning and release stages. Attached Figure Description

[0024] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] The inventors discovered through analysis of existing technologies that: First, impact point positioning relies on manual visual inspection or simple marking, and the manual operation process is not standardized, which easily leads to poor consistency and accuracy of test results and cannot meet the requirements of precise impact; Second, steel ball release relies on hand-held or simple conduit, and manual operation is prone to shaking, causing the vertical drop direction to deviate from the impact point; Third, height adjustment is mostly a single linear control with low precision, which cannot meet the requirements of high-precision testing.

[0026] Reference Figure 1 This document illustrates a structural schematic diagram of a steel ball impact testing device according to an embodiment of this application. Specifically, it may include the following structure: a laser collimation and positioning device, an electromagnetic release impact device, an orientation adjustment device, and a height precision adjustment device. One end of the orientation adjustment device is equipped with the electromagnetic release impact device, and the other end is equipped with the height precision adjustment device. A laser collimation and positioning device is provided on one side of the electromagnetic release impact device. The electromagnetic release impact device includes an electromagnet 1 and a steel ball 2. The electromagnet 1 has a slot 3 that can accommodate the steel ball 2, and the steel ball 2 is adsorbed within the slot 3. The laser beam projection path of the laser collimation and positioning device is collinear with the center of the slot 3, the center of the steel ball 2, and the sample impact point 18 in a vertical plane.

[0027] In the embodiments of this application, compared with the prior art where "impact point positioning relies on manual visual inspection", this application provides a solution that "achieves collinearity of the center of the slot 3, the center of the steel ball 2, and the sample impact point 18 through laser collimation positioning". Specifically, it includes a laser collimation positioning device, an electromagnetic release impact device, an orientation adjustment device, and a height precision adjustment device; one end of the orientation adjustment device is equipped with the electromagnetic release impact device, and the other end of the orientation adjustment device is equipped with the height precision adjustment device; one side of the electromagnetic release impact device is equipped with the laser collimation positioning device; the electromagnetic release impact device includes an electromagnet 1 and a steel ball 2; the electromagnet 1 is provided with a slot 3 that can accommodate the steel ball 2, and the steel ball 2 is adsorbed in the slot 3; the laser beam projection path of the laser collimation positioning device is collinear with the center of the slot 3, the center of the steel ball 2, and the sample impact point 18 in the vertical plane. The laser beam projection path of the laser collimation positioning device is strictly collinear with the center of the slot 3 of the electromagnet 1, the center of the steel ball 2, and the impact point 18 of the sample in the vertical plane. This replaces the traditional manual visual positioning and directly locks the spatial coordinates of the impact point through the linear characteristics of the laser, eliminating the subjective error of manual observation. The electromagnetic release impact device uses the electromagnet 1 to attract the steel ball 2 and uses the on and off of electromagnetic force to control the release of the steel ball 2. This avoids problems such as uneven force and contact deviation when manually placing or pushing the steel ball 2, ensuring that the initial position and speed of the steel ball 2 are consistent each time it is released. This improves the repeatability and accuracy of the test from both the positioning and release stages.

[0028] The following will further describe a steel ball impact testing device in this exemplary embodiment.

[0029] It should be noted that the functions of each device in this embodiment are interconnected as follows: the laser collimation and positioning device ensures precise locking of the spatial coordinates of the impact point, the electromagnetic release impact device realizes stable release of the steel ball 2, the orientation adjustment device adjusts the horizontal position of the sample, and the height precision adjustment device controls the falling height of the steel ball 2. The four devices work together to form a high-precision test closed loop.

[0030] As an example, the slot 3 of the electromagnet 1 can be designed to be circular or square; the relative positions of the electromagnetic release impact device and the laser collimation positioning device can be quickly calibrated through a standard interface to adapt to the testing needs of samples of different sizes.

[0031] In one specific implementation, the slot 3 of the electromagnet 1 is designed to be circular, and its size is designed according to the size of the steel ball 2. The power supply voltage of the electromagnetic release impact device is 12 volts. When the steel ball 2 is attracted to the slot 3 of the electromagnet 1, the interference fit of the inner diameter of the slot 3 ensures no shaking and avoids changes in air resistance caused by rotation during the fall.

[0032] In one embodiment of this application, the laser collimation and positioning device includes a ruby ​​laser 4 and a laser collimation switch 5; the ruby ​​laser 4 is disposed at the center position on one side of the slot 3, and the orientation adjustment device is provided with the laser collimation switch 5, which is electrically connected to the ruby ​​laser 4 to trigger the laser beam emission.

[0033] It should be noted that the laser collimation and positioning device uses the linear beam characteristics of the ruby ​​laser 4 to replace traditional manual visual positioning. The laser beam diameter, wavelength, and other parameters directly affect the positioning accuracy. The collinear design of the laser beam with the center of the slot 3, the center of the steel ball 2, and the sample impact point 18 ensures that the spatial coordinates of the sample impact point 18 can be accurately calibrated, avoiding test result distortion caused by positioning deviation.

[0034] As an example, the ruby ​​laser 4 can be replaced with a semiconductor laser.

[0035] In one embodiment of this application, the diameter of the laser beam is 2 mm, and the wavelength of the ruby ​​laser 4 is 630 nm.

[0036] It should be noted that the laser beam diameter is set to 2mm and the wavelength of the ruby ​​laser 4 is 630nm, which is the optimal combination of parameters that comprehensively considers the positioning accuracy requirements, environmental adaptability and equipment practicality of the steel ball 2 impact test.

[0037] As an example, the laser beam diameter is preferably in the range of 1mm-3mm. A 1mm diameter is suitable for high-precision positioning of small impact points, such as electronic components, where the beam coverage is relatively small. A 2mm diameter is a general-purpose option, suitable for impact points of conventional sizes, such as industrial sheet metal, balancing positioning accuracy and equipment cost. A 3mm diameter is suitable for large impact points, such as large structural components, where increased beam coverage improves adjustment efficiency. The laser collimation switch 5 can be triggered by a photoelectric sensor, replacing the traditional mechanical switch and improving trigger response speed.

[0038] In one specific implementation, the laser beam diameter is set to 2mm. The 2mm laser beam diameter ensures positioning accuracy while taking into account the versatility of the equipment. Its spot size can accurately cover the impact point of conventional samples (such as industrial plates, battery casings, etc.), and can also avoid positioning deviation caused by an excessively large spot. Furthermore, it does not rely excessively on high-precision adjustment equipment due to an excessively thin beam, thus reducing the stringent requirements on the operating environment.

[0039] In one embodiment of this application, the electromagnetic release impact device further includes an electromagnetic release switch 6; one end of the orientation adjustment device is connected to the electromagnet 1, and the orientation adjustment device is provided with the electromagnetic release switch 6; the electromagnetic release switch 6 is electrically connected to the electromagnet 1 to control the magnetic force of the electromagnet 1.

[0040] It should be noted that by controlling the on / off state of the electromagnetic force of the electromagnet 1 through the electromagnetic release switch 6, the release of the steel ball 2 can be achieved with "zero contact" automation: when the switch is triggered, the magnetic force of the electromagnet 1 disappears instantly, and the steel ball 2 falls freely under the action of gravity only, avoiding interference from human operation in the falling process, and significantly improving the consistency of the release of the steel ball 2 and the repeatability of the test results.

[0041] As an example, the electromagnetic release switch 6 can be a normally closed electromagnetic relay, an optocoupler-isolated solid-state relay, or a mechanically triggered push-button switch.

[0042] In one specific implementation, a push-button switch is used for manual triggering, which is convenient to operate. When the electromagnetic release switch 6 is in the on state, the electromagnet 1 generates a magnetic force at the slot 3. When the steel ball 2 approaches the slot 3 of the electromagnet 1, it is automatically and firmly attracted to the slot 3. When the electromagnetic release switch 6 is in the off state, the magnetic force at the slot 3 disappears instantly, and the steel ball 2 falls freely, impacting the sample impact point 18 vertically with a precise 2J impact energy. The vertical drop direction deviates from the angle of less than 1°, and one impact test is completed.

[0043] In one embodiment of this application, the orientation adjustment device includes a front-to-back adjustment rail 7 and a left-to-right adjustment rail 8; one end of the front-to-back adjustment rail 7 is connected to the electromagnet 1, and the front-to-back adjustment rail 7 is slidably connected to the left-to-right adjustment rail 8 via a first slider 9; the front-to-back adjustment rail 7 and the left-to-right adjustment rail 8 are perpendicularly connected to each other.

[0044] It should be noted that the orientation adjustment device consists of front and rear adjustment rails 7 and left and right adjustment rails 8, which can achieve continuous adjustment and locking within a large range in the front and rear and left and right directions, and can meet the requirements of continuous positioning of different sizes and multiple impact points.

[0045] As an example, linear ball bearing guides can be used instead of sliding guides to improve the smoothness of adjustment.

[0046] In one specific implementation, both the front-to-back adjusting guide rail 7 and the left-to-right adjusting guide rail 8 are linear ball bearing guide rails, connected to the electromagnetic release impact device via a graduated first slider 9. During adjustment, the left and right guide rails are manually pushed along the front-to-back guide rails until the laser beam is aligned with the sample impact point 18. The position is then fixed by the locking bolt, completing the precise positioning of the sample impact point 18. The low-friction characteristics of the linear ball bearing guide rails reduce adjustment resistance, and the graduated slider enables quantitative operation during coarse adjustment. The fixing method of the locking bolts avoids position drift during testing, and the adjustment range and accuracy meet the multi-impact point testing requirements of samples of different sizes.

[0047] In one embodiment of this application, the height precision adjustment device includes a vertical guide rail 10, a scale 11, a precision lead screw 12, and a stepper motor 13; the vertical guide rail 10 is slidably connected to the left and right adjustment guide rails 8 via a second slider 14, and the vertical guide rail 10 and the left and right adjustment guide rails 8 are perpendicularly connected to each other; a scale 11 is provided on one side of the vertical guide rail 10, and a precision lead screw 12 is provided on one side of the scale 11; the precision lead screw 12 is connected to the stepper motor 13 via a gear set, and the stepper motor 13 drives the precision lead screw 12 to rotate, thereby realizing the vertical movement of the orientation adjustment device.

[0048] It should be noted that the high precision adjustment device is used to control the falling height of the steel ball 2, that is, the distance from the bottom of the slot 3 of the electromagnet 1 to the impact point 18 of the sample. Its adjustment accuracy directly affects the impact energy. The energy is proportional to the square of the height. The cooperation between the precision lead screw 12 and the stepper motor 13 can achieve micron-level adjustment.

[0049] As an example, the scale 11 can be a digital scale 11; the precision lead screw 12 can be a ball screw to improve transmission accuracy.

[0050] In one specific implementation, the scale 11 is a digital scale 11, which is fixed to the side of the vertical guide rail 10 and directly displays the digital height value, thereby displaying the height position of the orientation adjustment device in real time and avoiding the reading error of traditional mechanical scales.

[0051] In one embodiment of this application, the highly precise adjustment device further includes a manual precision adjuster 15; the manual precision adjuster 15 is connected to one side of the stepper motor 13.

[0052] It should be noted that the manual adjuster is used for fine-tuning to provide flexibility and precision to meet different height requirements.

[0053] As an example, the manual precision adjuster 15 may employ a handwheel or a worm gear plus worm structure.

[0054] In one specific implementation, the manual precision adjuster 15 adopts a worm gear and worm shaft structure, working in conjunction with the stepper motor 13. It provides multiple adjustment modes, including electric fast adjustment, electric slow adjustment, manual adjustment, or a combination of these modes. During adjustment, the height is observed and adjusted using a scale 11, ensuring that the distance from the bottom of the impact steel ball 2 to the impact point is precisely adjusted to 408mm with an error not exceeding 2mm. This dual-mode design of electric and manual adjustment balances efficiency and precision.

[0055] In one embodiment of this application, a sample fixing base plate 16 is provided on one side of the high precision adjustment device, and a sample impact point 18 is provided on the sample fixing base plate 16.

[0056] It should be noted that the sample fixing base plate 16 is used to fix the sample to be tested, and its surface must be flat to avoid the sample impact point 18 shifting due to sample tilting.

[0057] As an example, the sample fixing base plate 16 can be made of aluminum alloy with a ground surface, and the sample can be fixed by bolts or vacuum adsorption.

[0058] In one specific implementation, the sample fixing base plate 16 is made of aluminum alloy with a ground surface. Before the test begins, the structure of the battery compartment and casing of the button battery or coin battery product is inspected to determine the vulnerable parts that may be released after the product undergoes an impact test. The product is marked and placed on the sample impact point 18 on the fixing base plate. The aluminum alloy base plate reduces the weight of the equipment and facilitates movement; the surface grinding process ensures that the sample is fixed flat and avoids horizontal displacement of the impact point due to the tilt of the base plate.

[0059] In one embodiment of this application, a level 17 is also included; the level 17 is mounted on one side of the orientation adjustment device.

[0060] It should be noted that the level 17 is used to calibrate the levelness of the base plate, ensuring that the falling path of the steel ball 2 is vertically aligned with the impact point, and avoiding horizontal displacement errors caused by the tilt of the base plate.

[0061] As an example, the level 17 can be a bubble level 17 or an electronic level 17, which is installed on the side of the orientation adjustment device for real-time monitoring of the levelness of the base plate.

[0062] In one specific implementation, the level 17 is a bubble level, mounted on one side of the orientation adjustment device via a magnetic base. When adjusting the levelness of the base plate, the bubble is centered by adjusting the left-right and front-back positions of the orientation adjustment device. The precision calibration of the bubble level 17 further improves the verticality of the falling path of the steel ball 2, ensuring the accuracy of the impact energy calculation.

[0063] In one embodiment of this application, the steel ball 2 has a diameter of 2 inches and a weight of 1.1 pounds.

[0064] It should be noted that the diameter and weight of steel ball 2 directly affect the impact energy and must be matched with the testing standards.

[0065] As an example, steel ball 2 can be made of stainless steel.

[0066] In one specific implementation, steel ball 2 is made of stainless steel, has a diameter of 2 inches, and weighs 1.1 pounds. The surface of steel ball 2 is polished. The corrosion resistance of stainless steel extends the service life of steel ball 2, ensuring hardness and corrosion resistance, and preventing deformation or rust from affecting the repeatability of the test during the test. Strict control of diameter and weight ensures the consistency of impact energy; the polished surface design eliminates the interference of rotation and shaking, improves the stability of the drop process, and significantly improves the repeatability of test results.

Therefore, the appended claims are intended to be interpreted as including both the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0068] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
