Description

Technical Field

[0001] The present invention relates to the technical field of laser target quality detection, and in particular to a detection device and method for a laser shooting target. Background Art

[0002] Accidental tipping tests for laser shooting training targets simulate the mechanical impact risks encountered in real-world use, fully verifying their structural strength and functional reliability. The test involves setting multiple drop heights based on typical application scenarios, and dropping them freely onto standard impact surfaces such as concrete or steel plates in different postures. The focus is on assessing the impact resistance of vulnerable points such as corners, flat surfaces, and sensor areas. The test is repeated multiple times, and extreme temperature conditions are applied when necessary to verify the material's tolerance to low-temperature brittleness or high-temperature softening. The damage assessment after the fall covers obvious structural damage such as shell cracking and deformation, seam cracking, as well as hidden defects such as internal bracket displacement and loose circuit board solder joints, and immediately powers on to test whether the laser detection sensitivity, feedback response and positioning accuracy are offset; however, at this stage, during the tipping detection process of laser shooting targets, the tipping and resetting of the target to be tested needs to be done manually by the staff, and after completing a tipping detection, the distance position of the laser emitter and the number of emission rings of the laser emitter need to be adjusted to verify whether the laser target is intact. Manual resetting, distance adjustment, and ring number setting in this process consume a lot of time, resulting in limited effective test times per day and low detection efficiency. Especially under the demand for large-scale detection, the efficiency bottleneck is particularly prominent; and the operator's placement force and angle fine-tuning will introduce human random errors, making it impossible to directly compare the results of multiple detections of the same target or multiple targets, thereby reducing the credibility of the data.

[0013] The present invention also provides a method for detecting a laser shooting target, such as the above-mentioned device for detecting a laser shooting target, comprising the following steps: S101: Place the laser target to be tested into the opposing target clamp, which is automatically locked to ensure that the laser target does not shake. After the laser target is clamped and stabilized, enter the test parameters on the PLC control panel, including the number of tilting times, laser emission distance, and number of shooting rings. Start the test command on the PLC control panel, and the inner flip release assembly is automatically powered off and unlocked. The opposing target clamp and the laser target are allowed to tilt freely as a whole until they hit the horizontal platform on the outer wall of the embossing table. S102: After the collision is completed, the chain-type centering and straightening assembly is instructed to operate by the opposing target clamp. The chain-type centering and straightening assembly initially straightens the tilted target in the opposing target clamp, so that the laser target is guided back to the center position of the opposing target clamp to ensure that the target can be accurately reset. Then, the outer double-arm flip assembly and the inner flip release assembly work together to accurately rotate the laser target back to the initial upright position. S103: After the laser target is reset, the staff starts the double-sided belt traction assembly through the PLC control panel to work. The double-sided belt traction assembly drives the support plate, the gear rack self-locking follow-up assembly, the screw linear adjustment module, and the laser emitter to move in the X-axis direction to drive the laser emitter to adjust the distance. The staff adjusts the position of the laser emitter through the screw linear adjustment module in advance to change the linear distance between the laser emitter and the center of the laser target, thereby covering different areas of the target surface.

After each test, the device executes the dumping and resetting process to complete multiple rounds of testing in a cycle.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the detection device and method for laser shooting targets are equipped with a steel frame, a double-side belt pulling assembly, a screw linear adjustment module, a gear rack self-locking rotation assembly, an inner flip release assembly, an opposing target clamp, a chain-type centering and straightening assembly and other structures that cooperate with each other, so that the laser target to be detected is limited by the opposing target clamp; when the dumping instruction is executed, the inner flip release assembly is powered off and the opposing target clamp and the clamped laser target dump until they hit the horizontal table, and then the chain-type centering and straightening assembly resets the dumped laser target in the opposing target clamp, and the outer double-arm flip assembly and the inner flip release assembly assist the laser target in rotating and resetting, so that it returns to a non-dumped state, and then the double-arm flip assembly is used to ... and then the double-arm flip assembly is used to assist the laser target in rotating and resetting, and then the double-arm flip assembly is used to The sideband traction assembly drives the laser emitter to adjust the distance, and the gear rack self-locking follow-up assembly adjusts the shooting position of the laser emitter to verify whether the function of the laser target is completed after the tipping, until multiple tests are repeated. Through mechanical automation, the whole process closed-loop control of laser target tipping, reset after tipping and laser design function verification is realized, which significantly improves the automation level of detection and experimental efficiency, reduces the error and labor intensity of manual operation, and the synergistic effect of multiple mechanisms not only ensures the safe reset of the target, but also optimizes the adjustment process of the laser emitter, ensuring the accuracy and consistency of multiple test results of the same target, which can meet the needs of multiple continuous and rapid tests, and improve the work efficiency of tipping detection and the quality control level of target products. After the dumping command is executed, the power is cut off by the inner flip release assembly, allowing the opposing target clamp and the clamped laser target to freely dump onto the impact platform. This process simulates the accidental drop or impact that the target may encounter in actual operation. The mechanized dumping action avoids the uncertainty caused by human operation. Then the chain-type centering and straightening assembly automatically resets the dumped laser target in the opposing target clamp. The automated design of this step greatly reduces manual intervention, improves detection efficiency and safety. Automatic straightening not only ensures that the target can accurately return to its initial position, but also avoids errors that may occur during manual reset, ensuring the accuracy of subsequent detection. Secondly, the outer double-arm flip assembly and the inner flip release assembly cooperate to assist the target in rotating and resetting, restoring it to a non-dumped state. The multi-mechanism design enhances the stability and reliability of the reset action. Mechanically assisted reset also effectively avoids the reset difficulty caused by the target's own weight or structural complexity, ensuring the consistency of the target state after each test, and helping to accurately evaluate the durability of the target under repeated impact. Secondly, after the target is reset, the double-sided belt traction assembly drives the laser emitter to adjust the long and short positions. Combined with the precise adjustment of the shooting position by the gear rack self-locking follow-up assembly, it can achieve flexible control of the shooting parameters of the laser emitter, which not only facilitates the multi-position and multi-distance verification of the laser target function, but also ensures the stability and repeatability of the shooting position. At the same time, the application of the gear rack self-locking follow-up assembly effectively prevents the position drift of the laser emitter, so that high-frequency repeated tests can be efficiently executed, meeting the durability verification requirements of batch targets, and each test can be carried out under preset conditions to ensure the validity of the test data.

The movable end of the gear rack self-locking follow-up assembly is mounted with a screw linear adjustment module 4, and the movable end of the screw linear adjustment module 4 is mounted with a laser emitter 5. The high precision and stability of the screw linear adjustment module 4 ensure the accuracy and repeatability of the position of the laser emitter 5 during the adjustment process, avoiding detection errors caused by position deviations, and its fine adjustment capability enables the laser shooting to be accurately aligned with the key detection area of ​​the target, thereby improving the reliability of the detection results. A double-sided belt traction assembly 6 for driving the support plate 2 to slide linearly along the X-axis is installed at the front and rear edges of the top of the steel frame 1. The steel frame 1 serves as the basic framework of the entire detection device and provides a solid and stable support structure. Its rigidity and stability ensure the positioning accuracy of each mechanical assembly during operation and avoid errors caused by frame deformation or vibration. An anti-overturn mechanism 13 is provided at the top of the steel frame 1 on the left side of the embossing table 9. The anti-overturn mechanism 13 is used to prevent the laser target from tipping toward the support plate 2. A PLC control panel 12 is installed on one side of the surface of the steel frame 1. The output end of the PLC control panel 12 is electrically connected to the input end of the laser emitter 5, the double-sided belt traction assembly 6, the outer double-arm flip assembly 7, the chain-type centering and straightening assembly 8, and the inner flip release assembly 10, respectively. The input end of the PLC control panel 12 is electrically connected to the output end of the laser emitter 5.

[0019] A method for detecting a laser shooting target in this embodiment, such as the above-mentioned device for detecting a laser shooting target, includes the following steps: S101: Place the laser target to be tested into the opposing target clamp 11. The opposing target clamp 11 is automatically locked to ensure that the laser target does not shake. After the laser target is clamped and stabilized, the test parameters are input into the PLC control panel 12, including the number of tipping times, laser emission distance, and number of shooting rings. The test command is started in the PLC control panel 12, and the inner flip release assembly 10 is automatically powered off and unlocked. The opposing target clamp 11 and the laser target are allowed to tip freely as a whole until they hit the horizontal platform 901 on the outer wall of the embossing table 9. S102: After the collision is completed, the chain-type centering and straightening assembly 8 is instructed to operate through the opposing target clamp 11. The chain-type centering and straightening assembly 8 initially straightens the tilted target in the opposing target clamp 11, so that the laser target is guided back to the center position of the opposing target clamp 11 to ensure that the target can be accurately reset. Then, the outer double-arm flip assembly 7 and the inner flip release assembly 10 work together to accurately rotate the laser target back to the initial upright position. S103: After the laser target is reset, the staff starts the double-side belt traction assembly 6 through the PLC control panel 12 to work. The double-side belt traction assembly 6 drives the support plate 2, the gear rack self-locking follow-up assembly 3, the screw linear adjustment module 4, and the laser emitter 5 to move in the X-axis direction to drive the laser emitter 5 to adjust the distance. The staff adjusts the position of the laser emitter 5 through the screw linear adjustment module 4 in advance to change the linear distance between the laser emitter 5 and the center of the laser target, so as to cover different areas of the target surface. In the process of the double-side belt traction assembly 6 driving the support plate 2, the screw linear adjustment module 4, and the laser emitter 5 to move, the gear rack self-locking follow-up assembly 3 also obtains rotational power, so that the laser emitter 5 can adjust its position; S104: After completing the position and distance adjustment, the staff starts the laser emitter 5 through the PLC control panel 12 to perform a shooting test. The laser emitter 5 shoots the target according to the set number of rings. The built-in sensor of the laser target feeds back the hit data to the PLC control panel 12 in real time, and automatically determines whether the detection sensitivity, response speed and positioning accuracy are qualified, thereby evaluating the functional integrity of the target; S105: Repeat the test several times continuously. After each test, the device executes the dumping and resetting process to complete multiple rounds of testing in a cycle.

[0020] Example 2, based on Example 1, Figure 7 、 Figure 8 and Figure 9 The outer double-arm flip assembly 7 includes a rotating shaft 701 mounted inside the steel frame 1 above the convex table 9 and side arms 703 fixed at both ends of the rotating shaft 701. A first stepper motor 702 is also installed on one side of the back of the steel frame 1 for driving the rotating shaft 701 to rotate. The input end of the first stepper motor 702 is electrically connected to the output end of the PLC control panel 12. The chain-type centering and straightening assembly 8 is installed between the two side arms 703. After the chain-type centering and straightening assembly 8 is used to complete the position reset of the laser target in the opposite target clamp 11, the staff controls the PLC through the PLC. The panel 12 opens the outer double-arm flip assembly 7 and the inner flip release assembly 10 to work. At this time, the first stepper motor 702 drives the rotating shaft 701 to rotate, and then the side arms 703 and the chain-type centering and straightening assembly 8 between the two side arms 703 deflect around the central axis of the rotating shaft 701 until the outer double-arm flip assembly 7 and the chain-type centering and straightening assembly 8 straighten the reset laser target. The double-arm design enhances the stability and force distribution of the reset action, so that the target can smoothly return to its initial state from the tilted state. Its mechanical assistance reduces the difficulty of reset caused by the complex structure or weight of the target. The chain-type centering and straightening assembly 8 guides the tilted target back to the clamping position through chain transmission, reducing manual intervention, improving the efficiency and accuracy of resetting, and ensuring that the target can return to the standard position each time it is tested, ensuring the consistency of the testing conditions. The chain-type centering and straightening assembly 8 includes a longitudinal beam plate 801 fixed between the two side arms 703, a rear frame 802 slidably mounted on the outer wall of the longitudinal beam plate 801 on one side close to the convex table 9, a front frame 803, and an X-axis chain traction mechanism 805 installed inside the rear frame 802 and the front frame 803. A Y-axis chain pulling mechanism 804 is installed on the outer wall of the other side of the longitudinal beam plate 801 for driving the rear frame 802 and the front frame 803 to move linearly toward each other; The moving end of the X-axis chain pulling mechanism 805 is installed with a slide 806. A servo motor 807 is installed on the outer wall of one side of the slide 806. The end of the drive shaft of the servo motor 807 passes through the outside of the slide 806 and is fixed with a silicone plate 808. The input end of the Y-axis chain pulling mechanism 804, the X-axis chain pulling mechanism 805, and the servo motor 807 are electrically connected to the output end of the PLC control panel 12. When the outer double-arm flip assembly 7 releases the laser target and the opposing target clamp 11, the laser target and the opposing target clamp 11 fall down and hit the horizontal table 901. The staff starts the chain-type centering and straightening assembly 8 through the PLC control panel 12 to work. At this time, the Y-axis chain pulling mechanism 804 drives the rear frame 802 and the front frame 803 to move closer to each other until the silicone plate 808 contacts the outer wall of the laser target and the laser target is centered in the opposing target clamp 11. At the same time, the staff can also start the X-axis chain traction mechanism 805 through the PLC control panel 12 to work, and use the X-axis chain traction mechanism 805 to drive the slide 806 and the silicone plate 808 to move in the X-axis direction, so that the centered laser target is stably inserted back into the opposing target clamp 11. After the outer double-arm flip assembly 7 and the chain-type centering and straightening assembly 8 complete the resetting of the target clamp 11 and the laser target, the chain-type centering and straightening assembly 8 is driven to fall down again through the PLC control panel 12 and the outer double-arm flip assembly 7.

[0021] Example 3, based on Example 2, Figure 11 and Figure 12 It is given that the inner flip release assembly 10 includes a second stepper motor 1001 installed on the outer wall of one side of the embossing table 9, a double-gear shaft 1002 fixed at the end of the driving shaft of the second stepper motor 1001, and a hollow double-gear cylinder 1003 coaxially mounted on the outer peripheral surface of the rotating shaft 701. The hollow double-gear cylinder 1003 and the double-gear shaft 1002 are meshed with each other, and the input end of the second stepper motor 1001 is electrically connected to the output end of the PLC control panel 12. During the operation of the outer double-arm flip assembly 7, the second stepper motor 1001 drives the double-gear shaft 1002 to rotate, and the double-gear shaft 1002 is used to drive the hollow double-gear cylinder 1003 and the opposing target clamp 11 to rotate until the laser target is in a vertical state. During this process, the hollow double-gear cylinder 1003 is fitted with the rotating shaft 701 and is in a coaxial state. The rotation of the rotating shaft 701 and the hollow double-gear cylinder 1003 does not affect each other, and only rotational friction occurs between the two. The opposing target clamp 11 includes a U-shaped base 1101 fixed to the top of the hollow double-toothed cylinder 1003, two double-C-mouth connecting beams 1102 slidingly symmetrically installed on the left and right sides of the top of the U-shaped base 1101, and a rubber plate 1103 installed on the outer wall of the two double-C-mouth connecting beams 1102. A plurality of equally spaced conical springs 1104 are installed on the left and right outer walls of the U-shaped base 1101. One end of the conical spring 1104 is fixedly connected to the outer wall of one side of the double-C-mouth connecting beam 1102. One side of the top of the convex platform 9 is provided with a 101 is a lower groove 902 that deflects around the central axis of the rotating shaft 701. When the staff uses the opposing target clamp 11 to fix the laser target, the lower end of the target is inserted between the two double C-mouth connecting beams 1102. At this time, the outer wall of the double C-mouth connecting beam 1102 contacts the outer wall of the laser target through the rubber plate 1103. At the same time, the multiple conical springs 1104 between the U-shaped base 1101 and the double C-mouth connecting beam 1102 will generate an elastic force to force the two double C-mouth connecting beams 1102 to stably fix the laser target to be tipped over.

[0022] Example 4, based on Example 2, Figure 13 and Figure 14 It is given that the double-sided belt traction assembly 6 includes a transmission belt X-axis traction structure 601 installed at the front and rear edges of the steel frame 1, a longitudinal axis 602 installed between the two transmission belt X-axis traction structures 601, and a reduction motor 603 installed on one side of the bottom of the steel frame 1. The end of the drive shaft of the reduction motor 603 is installed with a chain transmission structure 604 for driving the longitudinal axis 602 to rotate. The transmission belt X-axis traction structure 601 is used to drive the support plate 2, the gear rack self-locking follow-up assembly 3, the screw linear adjustment module 4, and the laser transmitter 5 along the X-axis direction. To move linearly, the double-sided belt traction assembly 6 drives the longitudinal shaft 602 to rotate through the reduction motor 603 and the chain transmission structure 604 when working. Then the longitudinal shaft 602 drives the support plate 2, the gear rack self-locking follow-up assembly 3, the screw linear adjustment module 4, and the laser emitter 5 to perform X-axis linear displacement through the transmission belt X-axis traction structure 601 on the front and rear sides of the steel frame 1 to adjust the distance between the laser emitter 5 and the laser target. This allows the detection to adapt to various shooting distance requirements, comprehensively evaluate the response performance of the target, and improve the comprehensiveness of the detection.
