Abstract
Description
Technical Field
[0001] This invention relates to the technical field of product testing, and in particular to a projectile testing device for electronic products. Background Technology
[0002] In the production and R&D of electronic products, ensuring product quality is paramount, as it directly impacts sales volume. Therefore, reliability testing is essential during R&D, simulating product launches at different angles and on different planes to observe structural and system reliability. Current technologies typically use manual methods to simulate launches at varying angles and speeds. This traditional approach is inefficient and lacks quantitative and qualitative analysis. Alternatively, robotic arms can be used to grip the product and launch it onto different inclines, but this requires significant space for the machines with varying slopes, and the robotic arms struggle to precisely control the launch speed, resulting in low accuracy for different launch speeds. A simple electronic product launch testing device capable of adjusting launch angles and speeds, and incorporating a linkage mechanism to ensure the device releases its connection to the carrier before impact, would solve these problems. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an electronic product projecting test device with a simple structure, adjustable projecting angle and projecting speed, and a linkage structure to ensure that the device is released from the carrier plate before the hard limit is reached before impact.
[0004] The technical solution adopted in this invention is as follows: This invention includes a supporting base plate and a testing module. The testing module includes a testing base plate, a handwheel lifting module, a product carrier plate, and a linkage ejection module. The rotating side of the testing base plate cooperates with the rotating side of the supporting base plate. The handwheel lifting module is located on the lifting side of the supporting base plate and cooperates with the corresponding side of the testing base plate. The product carrier plate slides with the upper surface of the testing base plate through several carrier plate slide rails. The linkage ejection module drives the product carrier plate to cooperate with the limiting block at the sliding end of the testing base plate, so that the product on the product carrier plate slides out.
[0005] Furthermore, the linkage ejection module includes an ejection motor, a linkage screw, and a linkage module. The ejection motor is located on one side of the upper surface of the test base plate, the linkage screw is connected to the movable end of the ejection motor, and the linkage screw cooperates with the product carrier plate through the linkage module.
[0006] Furthermore, the linkage module includes a linkage base plate, a sliding inclined block, a side-push limiting plate, and a V-shaped rotating block. The linkage base plate is slidably engaged with one side of the upper surface of the test base plate via a linkage slide rail. The sliding inclined block is located on one side of the sliding end of the upper surface of the test base plate. The side-push limiting plate is slidably engaged with the upper surface of the linkage base plate via a side-push slide rail. The movement directions of the side-push limiting plate and the linkage base plate are perpendicular to each other. The middle part of the V-shaped rotating block is hinged to the upper surface of the linkage base plate. The sliding rod at one end of the V-shaped rotating block is slidably engaged with the sliding groove at the far end of the side-push limiting plate. The rolling shaft at the other end of the V-shaped rotating block is engaged with the inclined surface of the sliding inclined block. The push-out motor drives the rolling shaft to engage with the inclined surface of the sliding inclined block via the linkage screw, and causes the limiting shaft at the near end of the side-push limiting plate to engage with the limiting buckle on the corresponding side of the product carrier plate.
[0007] Furthermore, a reset spring is provided between the linkage base plate and the side push limiting plate. The reset spring drives the limiting shaft at the near end of the side push limiting plate to engage with the limiting buckle on the corresponding side of the product carrier plate.
[0008] Furthermore, the handwheel lifting module includes a handwheel support frame, a handwheel screw, a sliding plate, a first rotating frame, a second rotating frame, and a connecting rod. The handwheel screw is rotatably engaged with the handwheel support frame at the lifting end of the supporting base plate. The sliding plate is slidably engaged with the supporting base plate via several handwheel slide rails. The handwheel screw engages with the sliding plate. The first rotating frame is disposed on the upper surface of the sliding plate, and the second rotating frame is disposed at the lifting end of the test base plate. The two ends of the connecting rod are respectively hinged to the first rotating frame and the second rotating frame. The handwheel screw drives the sliding plate to extend, causing the connecting rod to lift the second rotating frame.
[0009] Furthermore, product limiting strips are provided on both sides and the rear end of the product carrier plate, and the three sets of product limiting strips respectively cooperate with the limiting on both sides and the rear end of the product.
[0010] Furthermore, the product carrier plate is provided with a plurality of blocks, and the plurality of blocks cooperate with the corresponding limiting blocks.
[0011] Furthermore, a sensing baffle is provided on one side of the product carrier plate, and a number of photoelectric sensors are provided on the test base plate. The sensing baffle cooperates with the number of photoelectric sensors, and an angle sensor is also provided on the upper surface of the test base plate.
[0012] Furthermore, a buffer pad is provided on one side of the sliding end of the support base plate, and the buffer pad cooperates with the product sliding out of the product carrier plate.
[0013] Furthermore, an electrical control box module is provided on the upper surface of the support base plate.
[0014] The beneficial effects of this invention are: different projection angles can be adjusted before the projection test, and different projection angles can be tested on the same machine. At the same time, different projection speeds can be adjusted by electronic control. A linkage structure is provided at the connection with the carrier plate, which can release the connection with the carrier plate before the hard limit before the impact, realizing the separation of the deceleration of the linkage structure and the impact stopping action of the carrier plate. Projection compatibility with different products can be achieved by changing the carrier plate. The overall structure is compact, and the testing efficiency and applicability are higher.

Detailed Implementation
[0016] like Figures 1 to 7 As shown, in this embodiment, the present invention includes a supporting base plate 1 and a testing module 2. The testing module 2 includes a testing base plate 3, a handwheel lifting module 4, a product carrier plate 5, and a linkage ejection module 6. The rotating side of the testing base plate 3 cooperates with the rotating side of the supporting base plate 1. The handwheel lifting module 4 is located on the lifting side of the supporting base plate 1 and cooperates with the corresponding side of the testing base plate 3. The product carrier plate 5 slides with the upper surface of the testing base plate 3 through several carrier plate slide rails 7. The linkage ejection module 6 drives the product carrier plate 5 to cooperate with the limiting block 8 at the sliding end of the testing base plate 3, causing the product 9 on the product carrier plate 5 to slide out. Therefore, the handwheel lifting module 4 can adjust the relative angle between the testing base plate 3 and the supporting base plate 1 to achieve testing at different projection angles. The linkage ejection module 6 provides the ejection force and drives the product carrier plate 5 to slide at a certain speed, stopping at the limiting block 8 to allow the product 9 to be ejected under inertia, achieving the testing effect. The structure is simple and highly applicable.
[0017] like Figures 2 to 4As shown, in this embodiment, the linkage ejection module 6 includes an ejection motor 61, a linkage screw 62, and a linkage module 63. The ejection motor 61 is disposed on one side of the upper end face of the test base plate 3. The linkage screw 62 is connected to the movable end of the ejection motor 61, and the linkage screw 62 cooperates with the product carrier plate 5 through the linkage module 63. Therefore, by changing the rotation speed of the ejection motor 61, the ejection speed can be adjusted, allowing the linkage module 63 to push the product carrier plate 5 to move at different speeds.
[0018] like Figure 3 and Figure 4 As shown, in this embodiment, the linkage module 63 includes a linkage base plate 631, a sliding inclined block 632, a side-push limiting plate 633, and a V-shaped rotating block 634. The linkage base plate 631 is slidably engaged with one side of the upper surface of the test base plate 3 via a linkage slide rail 635. The sliding inclined block 632 is disposed on one side of the sliding end of the upper surface of the test base plate 3. The side-push limiting plate 633 is slidably engaged with the upper surface of the linkage base plate 631 via a side-push slide rail 636. The movement directions of the side-push limiting plate 633 and the linkage base plate 631 are perpendicular to each other. The V-shaped rotating block 634... The middle part of the moving block 634 is hinged to the upper surface of the linkage base plate 631. The sliding rod 637 at one end of the V-shaped rotating block 634 is slidably engaged with the sliding groove 638 at the far end of the side push limiting plate 633. The rolling shaft 639 at the other end of the V-shaped rotating block 634 is engaged with the inclined surface of the sliding inclined block 632. The push-out motor 61 drives the rolling shaft 639 to engage with the inclined surface of the sliding inclined block 632 through the linkage screw 62, and makes the limiting shaft 640 at the near end of the side push limiting plate 633 engage with the limiting buckle 10 on the corresponding side of the product carrier plate 5. Therefore, when the rolling shaft 639 is not in contact with the inclined surface of the sliding block 632, the limiting shaft 640 is engaged with the limiting buckle 10, allowing the linkage screw 62 to push the linkage base plate 631 and the product carrier plate 5 to move. When the product carrier plate 5 moves to a specific position, the rolling shaft 639 engages with the inclined surface of the sliding block 632, the V-shaped rotating block 634 rotates, and the limiting shaft 640 separates from the limiting buckle 10, completing the linkage peeling operation.
[0019] like Figure 4 As shown, in this embodiment, a return spring 11 is provided between the linkage base plate 631 and the side push limiting plate 633. The return spring 11 drives the limiting shaft 640 at the near end of the side push limiting plate 633 to engage with the limiting buckle 10 on the corresponding side of the product carrier plate 5. Therefore, when the rolling shaft 639 is not in contact with the inclined surface of the sliding block 632, the return spring 11 keeps the limiting shaft 640 stably locked within the limiting buckle 10, preventing displacement or detachment.
[0020] like Figure 1 , Figure 3 as well as Figure 6 As shown, in this embodiment, the handwheel lifting module 4 includes a handwheel support frame 41, a handwheel screw 42, a sliding plate 43, a first rotating frame 44, a second rotating frame 45, and a connecting rod 46. The handwheel screw 42 is rotatably engaged with the handwheel support frame 41 at the lifting end of the support base plate 1. The sliding plate 43 is slidably engaged with the support base plate 1 through several handwheel slide rails. The handwheel screw 42 is engaged with the sliding plate 43. The first rotating frame 44 is disposed on the upper surface of the sliding plate 43. The second rotating frame 45 is disposed at the lifting end of the test base plate 3. The two ends of the connecting rod 46 are respectively hinged to the first rotating frame 44 and the second rotating frame 45. The handwheel screw 42 drives the sliding plate 43 to push out, causing the connecting rod 46 to lift the second rotating frame 45. As can be seen, during the rotation of the handwheel screw 42, the sliding plate 43 is pushed out or reset, while the second rotating frame 45 is fixed to the lifting end of the test base plate 3. During the pushing out of the sliding plate 43, the first rotating frame 44 is pushed out simultaneously, and the second rotating frame 45 is lifted by the connecting rod 46 to realize the angle adjustment of the test base plate 3.
[0021] like Figure 7 As shown, in this embodiment, product limiting strips 12 are provided on both sides and the rear end of the product carrier plate 5. The three sets of product limiting strips 12 respectively cooperate with the sides and the rear end of the product 9 for limiting. It can be seen that the three sets of product limiting strips 12 limit the three sides of the product 9, ensuring that the product can only slide out along a fixed direction during the projectile process.
[0022] like Figure 3 and Figure 7 As shown, in this embodiment, the product carrier plate 5 is provided with a plurality of stops 13, and the plurality of stops 13 cooperate with the corresponding limiting blocks 8. Thus, during the ejection process of the product carrier plate 5, the stops 13 contact the limiting blocks 8 to stop the product carrier plate 5, and the product 9 slides out under the action of inertia, realizing the projectile operation.
[0023] like Figure 3 and Figure 7 As shown, in this embodiment, a sensing baffle 14 is provided on one side of the product carrier plate 5, and a plurality of photoelectric sensors 15 are provided on the test base plate 3. The sensing baffle 14 and the plurality of photoelectric sensors 15 are inductively coupled, and an angle sensor 16 is also provided on the upper surface of the test base plate 3. It can be seen that the sensing baffle 14 and the plurality of photoelectric sensors 15 can accurately locate the position of the product carrier plate 5 and calculate the end velocity of the product before it is launched.
[0024] like Figure 1 and Figure 2 As shown, in this embodiment, a buffer pad 17 is provided on one side of the sliding end of the support base plate 1, and the buffer pad 17 cooperates with the product 9 sliding out from the product carrier plate 5. Therefore, after the product 9 is launched, it falls onto the buffer pad 17, effectively preventing the product 9 from making hard contact with the machine surface and affecting the test results.
[0025] like Figure 1 and Figure 2 As shown, in this embodiment, an electrical control box module 18 is provided on the upper surface of the support base plate 1.
[0026] The working principle of this invention: Before the equipment starts, the linkage ejection module 6 drives the product carrier plate 5 to retract to the upper middle loading position of the test base plate 3. A manual or robotic arm places the product 6 to be tested onto the product carrier plate 5 for positioning. After positioning, the tilt angle of the test base plate 3 is adjusted by the handwheel lifting module 4. The angle sensor 16 provides feedback on the tilt angle of the test base plate 3. After loading and angle adjustment, the rotation speed of the ejection motor 61 is adjusted according to the projection speed. The reset spring 11 drives the limiting shaft 640 on the side push limiting plate 633 to engage with the limiting buckle 10, and the ejection motor 61 starts. The lead screw 62 drives the linkage base plate 631 to push out, and the side push limiting plate 633 drives the product carrier plate 5 to move. When the rolling shaft 639 interacts with the inclined surface of the sliding inclined block 632, the V-shaped rotating block 634 rotates, causing the limiting shaft 640 to separate from the limiting buckle 10. The product carrier plate 5 continues to slide obliquely downward at the separation speed. When several of the stops 13 contact the corresponding limiting blocks 8, the product carrier plate 5 is stopped. The product 9 on the product carrier plate 5 slides out under the action of inertia and falls onto the buffer pad 17. After the test is completed, each component is reset. The above steps are repeated to realize the multi-angle variable speed projectile test of electronic products.
[0027] Although the embodiments of the present invention are described with reference to actual solutions, they do not constitute a limitation on the meaning of the present invention. Modifications to the embodiments and combinations with other solutions based on this specification will be obvious to those skilled in the art.
