Description

Technical Field

[0001] The present disclosure relates to the field of testing technology, and in particular to a drop ball testing device and a drop ball testing system. Background Art

[0002] During the development of electronic devices, screens, battery covers, and other components are subjected to drop ball testing. This serves to verify the strength and reliability of the raw materials used to manufacture these devices, screening out substandard materials. It also verifies the degree of protection provided by each component to the entire device, preventing dents in the housing after the drop ball test, which could cause malfunctions. To ensure overall reliability, drop ball testing equipment is an essential component of electronic device manufacturing. This testing verifies the strength of the entire device, ensuring quality and minimizing after-sales service issues.

[0003] The existing solution involves using a positioner to aim a falling ball at an electronic product, then controlling the ball to hold and release it according to a control device. After the ball hits the product, a human has to manually retrieve it. With existing drop ball testing equipment, when the ball freely falls and hits the product, it rebounds a second time. This can easily injure a human trying to catch the ball. Furthermore, if the human fails to catch the ball, it can fall back onto the product, causing secondary damage and affecting test results. Summary of the Invention

[0010] Wherein, when the test ball hits the object to be tested, the test ball does not contact the ball receiving mechanism.

[0011] Furthermore, the ball receiving mechanism includes a moving part and a first driving part, the moving part cover is arranged on the outside of the test ball, the first driving part is arranged on the bracket, and the first driving part is connected to the moving part to drive the moving part to move along the free fall path of the test ball.

[0013] Furthermore, it further includes a controller, wherein the controller is connected to the first driving member;

[0014] The controller is used to control the first driving member so that after the test ball freely falls and hits the object to be tested, the moving member moves upward by a first distance so that the test ball cannot contact the object to be tested after rebounding.

[0015] Furthermore, the controller is used to control the first driving member so that after the test ball freely falls and hits the object to be tested, the moving member moves upward a second distance so that the test ball bounces back to its initial position.

[0016] Furthermore, the bracket is provided with a detection member, which is connected to the controller. The detection member is used to transmit the detected information of the falling of the test ball to the controller, and the controller is used to control the first driving member according to the information of the falling of the test ball.

[0017] Furthermore, the number of the connecting frames is four, the four connecting frames are parallel to each other, and the four connecting frames are arranged in a square.

[0018] Furthermore, the ball-dropping mechanism includes a clamping member and a second driving member connected to the clamping member, wherein the clamping member can clamp the test ball, and the second driving member is used to drive the clamping member so that the test ball can fall freely when the clamping member is opened.

[0019] Furthermore, a height adjustment mechanism is provided between the ball dropping mechanism and the bracket, and the height adjustment mechanism is used to adjust the height of the ball dropping mechanism.

[0020] A second aspect of the present disclosure provides a drop ball test system, comprising the drop ball test device described in the first aspect.

[0021] The technical solution provided by the embodiments of the present disclosure has the following advantages over the prior art:

[0022] The ball drop test device provided in the disclosed embodiments includes a base, a bracket, a ball drop mechanism, and a ball catcher. The base is formed with a test area for placing an object under test. During the ball drop test, the object under test, which can be a laptop computer, tablet computer, or the like, is placed in the test area.

[0029] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present disclosure without creative work shall fall within the scope of protection of the present disclosure.

[0030] Combine Figure 1 and Figure 2 As shown, the ball drop test apparatus provided in the disclosed embodiments includes a base 1, a bracket 2, a ball drop mechanism, and a ball catch mechanism. The base 1 is formed with a test area for placing a test object 7. During the ball drop test, the test object 7, which can be a laptop computer, tablet computer, or the like, is placed in the test area. The bracket 2 is mounted on the base 1. The ball drop mechanism is mounted on the bracket 2 and is capable of holding and releasing a test ball 6 for testing. The ball drop mechanism is positioned above the test area and can release the test ball 6, allowing it to freely fall along a path toward the test area. The ball catch mechanism is mounted on the bracket 2 and includes a clearance hole 321. The ball catch mechanism is positioned above the test object 7 before the test ball 6 is released. This allows at least a portion of the test ball 6 to pass through the clearance hole 321 and strike the test object 7. After the test ball 6 rebounds, the test ball 6 is prevented from contacting the test object 7. When the test ball 6 strikes the test object 7, it does not contact the ball catch mechanism. This embodiment uses a ball catching mechanism to catch the test ball 6 to prevent the test ball 6 from hitting the object to be tested 7 a second time. This not only avoids the risk of being injured by manual ball catching and improves the safety factor, but also avoids the problem of manual failure to catch the ball and improves the reliability of detection.

[0031] In this embodiment, the ball receiving mechanism does not contact the object to be tested 7, which can reduce the impact on the test results.

[0032] Optionally, the base 1 is provided with a positioning member 8, which can be a positioning block or a positioning groove. In this embodiment, by providing a positioning block on the base 1 and adding a ball receiving mechanism, a fully automated test can be achieved, making the test results more stable and avoiding inaccurate test results.

[0033] Optionally, the ball catching mechanism can be triggered by a sensor to precisely control the timing of catching the ball, making the test results more stable and accurate.

[0034] In some specific embodiments, the ball catching mechanism includes a moving member 3 and a first driving member, wherein the moving member 3 is covered on the outside of the test ball 6, and the first driving member is arranged on the bracket 2. The first driving member is connected to the moving member 3 and is used to drive the moving member 3 to move along the free-falling path of the test ball 6. Before the test ball 6 is released, the first driving member drives the moving member 3 to be arranged above the object to be tested 7. After the test ball 6 is released, at least part of the test ball 6 passes through the avoidance hole 321 and hits the object to be tested 7. After the test ball 6 rebounds, the first driving member drives the moving member 3 to move upward to prevent the test ball 6 from contacting the object to be tested 7, thereby preventing the test ball 6 from hitting the object to be tested 7 a second time. This not only avoids the risk of being injured by manual ball catching, thereby improving the safety factor, but also avoids the problem of manual failure to catch the ball, thereby improving the reliability of the detection.

[0035] The first driving member may be a motor or a cylinder, and an output end of the first driving member is connected to the moving member 3 for driving the moving member 3 to move.

[0036] In some specific embodiments, the movable member 3 includes a plurality of connecting frames 31 and a ball receiving ring 32. Each of the connecting frames 31 is connected to the ball receiving ring 32. The spacing between two adjacent connecting frames 31 is smaller than the diameter of the test ball 6, thereby preventing the test ball 6 from escaping from the movable member 3. The ball receiving ring 32 is provided with an escape hole 321. The diameter of the escape hole 321 is smaller than the diameter of the test ball 6. After the test ball 6 is released, at least a portion of the test ball 6 can pass through the escape hole 321 and strike the object to be tested 7.

[0037] In some specific embodiments, a controller is further included, and the controller is connected to the first driving member; the controller is used to control the first driving member so that after the test ball 6 freely falls and hits the object to be tested 7, the movable member 3 moves upward by a first distance, so that the test ball 6 cannot contact the object to be tested 7 after rebounding. The first driving member is controlled by the controller, and before the test ball 6 is released, the first driving member drives the movable member 3 to be set above the object to be tested 7. After the test ball 6 is released, at least part of the test ball 6 passes through the avoidance hole 321 and hits the object to be tested 7. After the test ball 6 rebounds, the first driving member drives the movable member 3 to move upward by a first distance to prevent the test ball 6 from contacting the object to be tested 7, thereby preventing the test ball 6 from hitting the object to be tested 7 a second time. This not only avoids the risk of being injured by manually catching the ball, thereby improving the safety factor, but also avoids the problem of manual failure to catch the ball, thereby improving the reliability of the detection.

[0038] In some specific embodiments, the controller is configured to control the first driving member so that after the test ball 6 freely falls and strikes the object to be tested 7, the movable member 3 moves upward a second distance, causing the test ball 6 to rebound and return to its initial position. This allows the drop ball testing device to return to its initial state, thereby enabling repeated and multiple drop ball tests on the object to be tested 7. This embodiment allows for repeated testing without the need to manually pick up the dropped ball.

[0039] In some specific embodiments, the bracket 2 is provided with a detection member 5, which is connected to a controller. The detection member 5 is used to transmit the information of the falling test ball 6 to the controller, and the controller is used to control the first driving member according to the information of the falling test ball 6. Before the test ball 6 is released, the first driving member drives the movable member 3 to be set above the object to be tested 7. The detection member 5 is combined with the first driving member. When the test ball 6 falls freely, the detection member 5 detects the test ball 6. The test ball 6 passes through the avoidance hole 321 and abuts against the object to be tested 7. The test ball 6 rebounds. The first driving member drives the movable member 3 to move upward to the ball receiving position to catch the test ball 6, preventing the test ball 6 from hitting the object to be tested 7 a second time. This not only avoids the risk of being injured by manual ball catching, thereby improving the safety factor, but also avoids the problem of manual failure to catch the ball, thereby improving the reliability of the detection. The controller is used to control the first driving member so that the test ball 6 freely falls and hits the object to be tested 7. The movable member 3 then moves upward a second distance, causing the test ball 6 to rebound and return to its initial position. This allows the drop ball testing device to return to its initial state, thereby enabling repeated and multiple drop ball tests on the object to be tested 7. This embodiment allows for repeated testing without the need to manually pick up the dropped ball.

[0040] The detection element 5 can be a sensor, or a grating, etc.

[0041] In some specific embodiments, there are four connecting frames 31, which are parallel to each other and arranged in a square. After the test ball 6 rebounds, the first driving member drives the connecting frames 31 upward to the ball receiving position to catch the test ball 6, preventing the test ball 6 from hitting the test object 7 a second time. This not only avoids the risk of injury from manual ball catching, thereby improving the safety factor, but also avoids the problem of manual ball catching, thereby improving the reliability of the test.

[0042] In some specific embodiments, the ball-dropping mechanism includes a clamping member and a second driving member connected to the clamping member, wherein the clamping member can clamp the test ball 6, and the second driving member is used to drive the clamping member so that when the clamping member is opened, the test ball 6 can fall freely. Before the test ball 6 is released, the first driving member drives the movable member 3 to be set above the test area, and the second driving member drives the clamping member to release the test ball 6. The detection member 5 is combined with the first driving member. When the test ball 6 falls freely, the detection member 5 detects the test ball 6, and the test ball 6 passes through the avoidance hole 321 and abuts against the object to be tested 7. The test ball 6 rebounds, and the first driving member drives the movable member 3 to move upward to the ball receiving position to receive the test ball 6, thereby preventing the test ball 6 from hitting the object to be tested 7 a second time. The controller then controls the first drive member to cause the test ball 6 to freely fall and strike the object under test 7. The movable member 3 then moves upward a second distance, causing the test ball 6 to rebound and return to its initial position. The second drive member then drives the clamping member to hold the test ball 6, restoring the drop ball test device to its initial state. This allows for repeated, multiple drop ball tests on the object under test 7. This embodiment allows for repeated testing without the need to manually pick up the dropped ball.

[0043] In some specific embodiments, a height adjustment mechanism is provided between the ball dropping mechanism and the bracket 2 , and the height adjustment mechanism is used to adjust the height of the ball dropping mechanism, thereby adjusting the initial height of the test ball 6 .

[0044] In some specific embodiments, the test process includes the following steps: (1) initial state of the drop ball test device;

[0045] (2) Place the object to be tested 7 into the device and start the device;

[0046] (3) The moving member 3 falls above the object to be measured 7 (without contacting the object to be measured 7);

[0047] (4) Activate the ball drop switch, and the second driving member is used to drive the clamping member to release the test ball 6. After the test ball 6 passes through the detection member 5, the upward switch of the moving member 3 is activated at the same time;

[0048] (5) After the test ball 6 hits the object to be tested 7, the moving part 3 will move the test ball 6 upward away from the surface of the object to be tested 7 to avoid a secondary impact on the object to be tested 7.

[0049] In some specific implementations, the time required for the test ball to fall to the surface of the object to be tested is directly related to the test height. Currently, commonly used test heights are 15CM, 20CM, and 25CM.

[0050] When the detection part is an inductive grating, the response time of the inductive grating is usually between 6ms and 10ms. Taking the minimum height of 15cm as an example (as shown in the following formula), the falling time is 175ms, and 10ms<<175ms. Therefore, the inductive grating has enough time to respond and transmit the signal to the moving part, ensuring that the falling test ball is lifted immediately after hitting the object to be tested to avoid secondary collision.

[0051] Test the ball's drop time Formula height h = 1 / 2gt 2 Where g is the acceleration due to gravity, usually 9.8m / s 2 To ensure full contact between the ball and the test surface, the moving element quickly lifts the ball away from the test surface 175ms after the ball passes through the grating. These parameters can be set and stored in the controller based on the specific test height for future use.

[0052] The ball drop test system provided in the embodiment of the present disclosure includes the ball drop test device provided in the embodiment of the present disclosure. Since the ball drop test system provided in the embodiment of the present disclosure has the same advantages as the ball drop test device provided in the embodiment of the present disclosure, they will not be described in detail here.

[0053] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this embodiment can be achieved. This is not limited herein.

[0054] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure.
