Description

Technical Field

[0001] This invention relates to the field of laser target quality inspection technology, specifically to a testing device and method for laser shooting targets. Background Technology

[0002] Accidental tipping tests on laser shooting training targets simulate the mechanical impact risks of real-world use, comprehensively verifying their structural strength and functional reliability. The tests involve setting multiple drop heights based on typical application scenarios and allowing the targets to fall freely onto standard impact surfaces such as concrete or steel plates in different postures. The focus is on examining the impact resistance of vulnerable points such as edges, flat surfaces, and sensor areas. The experiments are repeated multiple times, and extreme temperature conditions are sometimes added to test the material's tolerance to low-temperature embrittlement or high-temperature softening states. Damage assessment after a drop includes visible structural damage such as shell cracking and deformation, and seam cracking, as well as hidden defects such as internal support displacement and loose circuit board solder joints. Immediate power-on testing is then conducted to check for deviations in laser detection sensitivity, feedback response, and positioning accuracy. However, currently, during the tilting test of laser-firing targets, the tilting and repositioning of the target must be manually performed by staff. After each tilting test, the distance and number of laser emitters need to be adjusted to verify the integrity of the target. This process of manual repositioning, distance adjustment, and ring setting consumes a significant amount of time, limiting the number of effective tests per day and resulting in low testing efficiency, especially under high-volume testing requirements. Furthermore, the operator's placement force and angle adjustments introduce random human error, making direct comparisons of results from multiple tests on the same target or multiple tests on multiple targets impossible, thus reducing data reliability. Summary of the Invention

[0003] The purpose of this invention is to provide a detection device and method for laser shooting targets. The laser target to be tested is limited by an opposing target clamp. When a tilting command is executed, the inner flip release assembly is de-energized, and the opposing target clamp and the clamped laser target tilt until they impact the horizontal platform. Subsequently, a chain-type centering and straightening assembly resets the tilted laser target in the opposing target clamp. The outer double-arm type flip assembly and the inner flip release assembly together assist the laser target in rotating and resetting, returning it to an untilted state. Then, a double-sided belt traction assembly drives the laser emitter to adjust its distance, and a gear and rack self-locking follow-rotation assembly adjusts the firing position of the laser emitter to verify whether the function of the tilted laser target is completed. This process is repeated multiple times, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a detection device for laser shooting targets, comprising:

The input terminal of the PLC control panel is electrically connected to the output terminal of the laser emitter.

[0007] Preferably, the external double-arm type flipping assembly includes a rotating shaft rotatably mounted inside a steel frame above the convex type platform and side arms fixed at both ends of the rotating shaft.

[0009] Preferably, the moving end of the X-axis chain traction mechanism is equipped with a slide table, and a servo motor is installed on one outer wall of the slide table. The drive shaft end of the servo motor extends through to the outside of the slide table and is fixed with a silicone plate. The input ends of the Y-axis chain pull mechanism, the X-axis chain traction mechanism, and the servo motor are electrically connected to the output end of the PLC control panel.

[0010] Preferably, the inner flip release assembly includes a second stepper motor mounted on the outer wall of one side of the convex type, a double gear shaft fixed at the end of the drive shaft of the second stepper motor, and a hollow double gear cylinder rotatably mounted on the outer circumferential surface of the shaft on the same axis. The hollow double gear cylinder and the double gear shaft mesh with each other, and the input end of the second stepper motor is electrically connected to the output end of the PLC control panel.

[0011] Preferably, the opposing target clamp includes a U-shaped base fixed to the top of the hollow double-toothed cylinder, two double C-shaped connecting beams slidably and symmetrically installed on the left and right sides of the top of the U-shaped base, and rubber plates installed on the outer walls of the two double C-shaped connecting beams close to each other. Several equally spaced conical springs are installed on the left and right outer walls of the U-shaped base, and one end of the conical spring is fixedly connected to one side of the outer wall of the double C-shaped connecting beam.

[0012] Preferably, one side of the top of the raised character platform is provided with a lower groove for the U-shaped base to deflect around the central axis of the rotating shaft.

[0013] Preferably, the double-sided belt traction assembly includes a transmission belt X-axis traction structure installed at the front and rear edges inside the steel frame, a longitudinal shaft installed between the two transmission belt X-axis traction structures, and a geared motor installed on one side of the bottom of the steel frame. The drive shaft end of the geared motor is equipped with a chain transmission structure for driving the longitudinal shaft to rotate. The transmission belt X-axis traction structure is used to drive the support plate, the gear and rack self-locking rotating assembly, the lead screw linear adjustment module, and the laser emitter to move linearly along the X-axis direction.

[0014] Preferably, the self-locking rack and pinion rotating assembly includes a rack body fixed to the inner wall of one side of the steel frame, an L-shaped back seat fixed to the outer wall of one side of the support plate, a rotary ring rotatably mounted on the outer wall of the other side of the support plate, and a drive wheel rotatably mounted at the corner of the outer wall of the other side of the support plate. The drive wheel and the rotary ring are in contact with each other. A worm shaft is rotatably mounted on the outer wall of one side of the L-shaped back seat. One end of the worm shaft passes through the outside of the L-shaped back seat and is fixed with a gear body that meshes with the rack body. One end of one of the drive wheels passes through the outside of the L-shaped back seat and is mounted with a worm gear shaft. The worm gear shaft and the worm shaft mesh with each other.

[0015] The present invention also provides a method for detecting laser shooting targets, as described above, comprising the following steps:

[0016] S101: Place the laser target to be tested into the opposing target clamp. The opposing target clamp will automatically lock to ensure that the laser target does not shake. After the laser target is clamped and stabilized, input the test parameters into the PLC control panel, including the number of tilts, laser emission distance, and number of firing rings. Start the test command in the PLC control panel. The inner flip release assembly will automatically power off and unlock. The opposing target clamp and the laser target will tilt freely until they hit the horizontal platform on the outer wall of the convex platform.

[0017] S102: After the impact is completed, the opposing target clamping device commands the chain-type centering and straightening assembly to operate. The chain-type centering and straightening assembly initially straightens the tilted target in the opposing target clamping device, so that the laser target is guided back to the center position of the opposing target clamping device, ensuring that the target can be accurately reset. Then, the outer double-arm type flipping assembly and the inner flipping release assembly work together to precisely rotate the laser target back to the initial upright position.

[0018] S103: After the laser target is reset, the operator starts the double-sided belt traction assembly through the PLC control panel. The double-sided belt traction assembly drives the support plate, the rack and pinion self-locking follow-up assembly, the lead screw linear adjustment module, and the laser emitter to move in the X-axis direction, thereby adjusting the laser emitter's position. The operator pre-adjusts the position of the laser emitter through the lead screw linear adjustment module to change the straight-line distance between the laser emitter and the center of the laser target, thus covering different areas of the target surface. During the movement of the support plate, the lead screw linear adjustment module, and the laser emitter driven by the double-sided belt traction assembly, the rack and pinion self-locking follow-up assembly also receives rotational power, causing the laser emitter to adjust its position.

[0019] S104: After completing the position and distance adjustment, the staff starts the laser emitter through the PLC control panel to perform the shooting test. The laser emitter shoots the target according to the set ring number. The built-in sensor of the laser target feeds back the hit data to the PLC control panel in real time, automatically judging whether the detection sensitivity, response speed and positioning accuracy are qualified, thereby evaluating the functional integrity of the target.

[0020] S105: Repeated tests are performed continuously. After each test, the device executes a tilting and resetting process, and multiple rounds of testing are completed in a loop.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: The laser target detection device and method are configured with a steel frame, a double-sided belt traction assembly, a lead screw linear adjustment module, a gear and rack self-locking rotating assembly, an inner flip release assembly, an opposing target clamp, and a chain-type centering and straightening assembly, etc., which cooperate with each other. The laser target to be detected is limited by the opposing target clamp. When the tilting command is executed, the inner flip release assembly is de-energized, and the opposing target clamp and the clamped laser target tilt until they hit the horizontal platform. Then, the chain-type centering and straightening assembly resets the tilted laser target in the opposing target clamp, and the outer double-arm type flip assembly and the inner flip release assembly together assist the laser target to rotate and reset, so that it returns to the untilted state. After that, the double... The side-belt traction assembly drives the laser emitter to adjust its distance, while the rack and pinion self-locking rotating assembly adjusts the firing position of the laser emitter to verify whether the function of the tilted laser target is completed. This process is repeated multiple times. Through mechanical automation, the entire process of tilting, resetting, and verifying the laser design function of the laser target is controlled in a closed loop. This significantly improves the automation level and experimental efficiency of the test, reduces human error and labor intensity, and the synergistic effect of multiple mechanisms not only ensures the safe resetting of the target but also optimizes the adjustment process of the laser emitter. This ensures the accuracy and consistency of the test results of the same target multiple times, meets the needs of multiple continuous and rapid tests, and improves the work efficiency of tilting tests and the quality control level of target products.

[0022] After the tilting command is executed, the internal flip-release assembly cuts off power, allowing the opposing target holder and the clamped laser target to tilt freely onto the impact platform. This process simulates the accidental drop or impact that the target might encounter in actual operation. The mechanized tilting action avoids the uncertainty caused by human operation. Subsequently, the chain-type centering and straightening assembly automatically resets the tilted laser target in the opposing target holder. This automated design greatly reduces human intervention, improves testing 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 testing. Secondly, the external double-arm flip-release assembly and the internal flip-release assembly work together to assist the target in rotating and resetting, restoring it to its untilted state. The multi-mechanism design enhances the stability and reliability of the reset action. Mechanically assisted reset also effectively avoids reset difficulties caused by the target's own weight or structural complexity, ensuring the consistency of the target's state after each test and helping to accurately evaluate the durability of the target under repeated impacts.

[0023] Secondly, after the target is reset, the double-sided belt traction assembly drives the laser emitter to adjust its position, and combined with the gear and rack self-locking follow-rotation assembly for precise adjustment of the firing position, it enables flexible control of the laser emitter's firing parameters. This not only facilitates multi-position and multi-distance verification of the laser target's function, but also ensures the stability and repeatability of the firing position. At the same time, the application of the gear and rack self-locking follow-rotation assembly effectively prevents the laser emitter's position drift, enabling high-frequency repeated tests to be executed efficiently, meeting the durability verification requirements of batch targets, and ensuring that each test can be conducted under preset conditions, thus guaranteeing the validity of the test data.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] Example 1, by Figures 1 to 6 The present invention includes a steel frame 1, a raised plate 9 fixed at the bottom right side of the steel frame 1, and a horizontal plate 901 integrally formed on one side outer wall of the raised plate 9. An inner flip release assembly 10 is installed on the other side outer wall of the raised plate 9, and an opposing target clamp 11 for clamping laser target is installed at the drive end of the inner flip release assembly 10. An outer double-arm type flip assembly 7 is installed inside the steel frame 1 on one side of the opposing target clamp 11, and a chain-type centering and straightening assembly 8 is installed at the drive end of the outer double-arm type flip assembly 7.

[0041] Support plate 2 is slidably installed on one side of the top of the steel frame 1. A gear and rack self-locking rotating assembly is installed on the outer wall of the support plate 2 near the convex platform 9. A lead screw linear adjustment module 4 is installed on the movable end of the gear and rack self-locking rotating assembly, and a laser emitter 5 is installed on the moving end of the lead screw linear adjustment module 4. The high precision and stability of the lead screw linear adjustment module 4 ensure the accuracy and repeatability of the position of the laser emitter 5 during the adjustment process, avoids detection errors caused by position deviation, and its fine adjustment capability enables the laser to accurately aim at the key detection area of ​​the target, improving the reliability of the detection results.

[0042] At the front and rear edges of the top of the steel frame 1, a double-sided belt traction assembly 6 is installed to drive the support plate 2 to slide linearly along the X-axis. The steel frame 1 serves as the basic frame of the entire testing device, providing a robust 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-tipping mechanism 13 is installed at the top of the steel frame 1 on the left side of the convex character platform 9. The anti-tipping mechanism 13 is used to prevent the laser target from tilting towards the support plate 2. A PLC control panel 12 is installed on one side of the surface of the steel frame 1. The output terminals of the PLC control panel 12 are electrically connected to the input terminals of the laser emitter 5, the double-sided belt traction assembly 6, the outer double-arm type flipping assembly 7, the chain-type centering and straightening assembly 8, and the inner flipping release assembly 10, respectively. The input terminal of the PLC control panel 12 is electrically connected to the output terminal of the laser emitter 5.

[0043] This embodiment provides a method for detecting a laser shooting target, using the aforementioned laser shooting target detection device, which includes the following steps:

[0044] S101: Place the laser target to be tested into the opposing target clamp 11. The opposing target clamp 11 automatically locks to ensure that the laser target does not shake. After the laser target is clamped and stabilized, input the test parameters into the PLC control panel 12, including the number of tilts, laser emission distance, and number of firing rings. Start the test command in the PLC control panel 12. The inner flip release assembly 10 automatically de-energizes and unlocks. The opposing target clamp 11 and the laser target tilt freely until they hit the horizontal platform 901 on the outer wall of the convex platform 9.

[0045] S102: After the impact is completed, the opposing target clamp 11 commands the chain-type centering and straightening assembly 8 to operate. 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, ensuring that the target can be accurately reset. Then, the outer double-arm type flipping assembly 7 and the inner flipping release assembly 10 work together to precisely rotate the laser target back to the initial upright position.

[0046] S103: After the laser target is reset, the operator starts the double-sided belt traction assembly 6 through the PLC control panel 12. The double-sided belt traction assembly 6 drives the support plate 2, the gear and rack self-locking follow-up assembly 3, the lead screw linear adjustment module 4, and the laser emitter 5 to move in the X-axis direction, so as to adjust the position of the laser emitter 5. The operator adjusts the position of the laser emitter 5 in advance through the lead screw linear adjustment module 4 to change the linear distance between the laser emitter 5 and the center of the laser target, thereby covering different areas of the target surface. During the process of the double-sided belt traction assembly 6 driving the support plate 2, the lead screw linear adjustment module 4, and the laser emitter 5 to move, the gear and rack self-locking follow-up assembly 3 will also obtain rotational power, so that the laser emitter 5 can adjust its position.

[0047] S104: After completing the position and distance adjustment, the staff starts the laser emitter 5 through the PLC control panel 12 to perform the shooting test. The laser emitter 5 shoots at the target according to the set ring number. The built-in sensor of the laser target feeds back the hit data to the PLC control panel 12 in real time, automatically judging whether the detection sensitivity, response speed and positioning accuracy are qualified, thereby evaluating the functional integrity of the target.

[0048] S105: Repeated tests are performed continuously. After each test, the device executes a tilting and resetting process, and multiple rounds of testing are completed in a loop.

[0049] Example 2, based on Example 1, is... Figure 7 , Figure 8 and Figure 9 The external double-arm tilting assembly 7 includes a rotating shaft 701 rotatably mounted inside a steel frame 1 above the convex platform 9, and side arms 703 fixed at both ends of the rotating shaft 701. A first stepper motor 702 for driving the rotating shaft 701 is also installed on one side of the back of the steel frame 1. The input end of the first stepper motor 702 is electrically connected to the output end of the PLC control panel 12. A chain-type centering and straightening assembly 8 is installed between the two side arms 703. After the laser target is reset in the opposing target clamp 11 using the chain-type centering and straightening assembly 8, the operator controls the PLC... When panel 12 is opened, the outer double-arm type flip assembly 7 and the inner flip release assembly 10 are put into operation. At this time, the first stepper motor 702 drives the rotating shaft 701 to rotate. Then, the side arm 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 type flip assembly 7 and the chain-type centering and straightening assembly 8 straighten the laser target after reset. The double-arm design enhances the stability and force distribution of the reset action, so that the target can be smoothly restored from the tilted state to the initial state. Its mechanical assistance reduces the reset difficulty caused by the complex structure or weight of the target.

[0050] The chain-type centering and straightening assembly 8 guides the tilted target back to the clamping position through chain transmission, reducing manual intervention and improving the efficiency and accuracy of reset. At the same time, it ensures that the target can return to the standard position every time it is tested, ensuring the consistency of the test 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 and a front frame 803 slidably installed on the outer wall of the longitudinal beam plate 801 near the convex platform 9, 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 other outer wall of the longitudinal beam plate 801 to drive the rear frame 802 and the front frame 803 to move in opposite directions in a straight line.

[0051] The moving end of the X-axis chain traction mechanism 805 is equipped with a slide table 806. A servo motor 807 is installed on one outer wall of the slide table 806. The end of the drive shaft of the servo motor 807 extends through to the outside of the slide table 806 and is fixed with a silicone plate 808. The input ends of the Y-axis chain pull mechanism 804, the X-axis chain traction mechanism 805, and the servo motor 807 are electrically connected to the output end of the PLC control panel 12.

[0052] After the outer double-arm type flip assembly 7 releases the laser target and the opposing target clamp 11, the laser target and the opposing target clamp 11 tilt and impact the horizontal table 901. The operator starts the chain-type centering and straightening assembly 8 through the PLC control panel 12. 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 operator can also start the X-axis chain traction mechanism 805 through the PLC control panel 12. The X-axis chain traction mechanism 805 drives the slide table 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.

[0053] After the outer double-arm type flipping assembly 7 and the chain-type centering and straightening assembly 8 have completed the reset of the opposing 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 type flipping assembly 7.

[0054] Example 3, based on Example 2, by Figure 11 and Figure 12The inner flip-release assembly 10 includes a second stepper motor 1001 mounted on the outer wall of one side of the convex plate 9, a double gear shaft 1002 fixed at the end of the drive shaft of the second stepper motor 1001, and a hollow double gear cylinder 1003 rotatably mounted on the outer circumference of the rotating shaft 701 along the same axis. The hollow double gear cylinder 1003 and the double gear shaft 1002 mesh with each other. 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 type flip assembly 7, the second stepper motor 1001 drives the double gear shaft 1002 to rotate, and the double gear shaft 1002 drives 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 will not affect each other, and only rotational friction occurs between them.

[0055] The opposing target clamp 11 includes a U-shaped base 1101 fixed to the top of a hollow double-toothed cylinder 1003, two double C-shaped connecting beams 1102 slidably and symmetrically installed on the left and right sides of the top of the U-shaped base 1101, and rubber plates 1103 installed on the outer walls of the two double C-shaped connecting beams 1102 that are close to each other. Several equally spaced conical springs 1104 are installed on the left and right outer walls of the U-shaped base 1101. One end of each conical spring 1104 is fixedly connected to one side of the outer wall of the double C-shaped connecting beam 1102. A support is provided on one side of the top of the convex platform 9 for the U-shaped base 1101 to... The lower groove 902, which deflects around the central axis of the rotating shaft 701, allows the operator to fix the laser target using the opposing target clamp 11. The lower end of the target is inserted between the two double C-port connecting beams 1102. At this time, the outer wall of the double C-port connecting beam 1102 contacts the outer wall of the laser target through the rubber plate 1103. Meanwhile, multiple conical springs 1104 between the U-shaped base 1101 and the double C-port connecting beam 1102 will generate elastic force to force the two double C-port connecting beams 1102 to stably fix the laser target to be tilted for testing.

[0056] Example 4, based on Example 2, by Figure 13 and Figure 14The double-sided belt traction assembly 6 includes a transmission belt X-axis traction structure 601 installed at the front and rear edges inside the steel frame 1, a longitudinal shaft 602 installed between the two transmission belt X-axis traction structures 601, and a geared motor 603 installed on one side of the bottom of the steel frame 1. The drive shaft end of the geared motor 603 is equipped with a chain drive structure 604 for driving the longitudinal shaft 602 to rotate. The transmission belt X-axis traction structure 601 is used to drive the support plate 2, the gear and rack self-locking follow-rotation assembly 3, the lead screw linear adjustment module 4, and the laser emitter 5 along the X-axis direction. During operation, the double-sided belt traction assembly 6 drives the longitudinal shaft 602 to rotate via the reduction motor 603 and chain drive structure 604. The longitudinal shaft 602 then drives the support plate 2, the gear rack self-locking rotating assembly 3, the lead 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. This adjusts the distance between the laser emitter 5 and the laser target, enabling the detection to adapt to various shooting distance requirements, comprehensively evaluate the response performance of the target, and improve the comprehensiveness of the detection.

[0057] The self-locking rack and pinion rotating assembly 3 includes a rack body 301 fixed to the inner wall of one side of the steel frame 1, an L-shaped back seat 303 fixed to the outer wall of one side of the support plate 2, a rotating ring 302 rotatably mounted on the outer wall of the other side of the support plate 2, and a drive wheel 307 rotatably mounted at the corner of the outer wall of the other side of the support plate 2. The drive wheel 307 and the rotating ring 302 are in contact with each other. A worm shaft 304 is rotatably mounted on the outer wall of one side of the L-shaped back seat 303. One end of the worm shaft 304 passes through the outside of the L-shaped back seat 303 and is fixed with a gear body 306 that meshes with the rack body 301. One end of one drive wheel 307... A worm gear shaft 305 is installed on the outside of the L-shaped back seat 303. The worm gear shaft 305 and the worm shaft 304 mesh with each other. During the sliding of the support plate 2, one end of the worm shaft 304 meshes with the gear body 306 and the rack body 301. As a result, the worm shaft 304 is driven to rotate, which in turn drives the worm gear shaft 305 and the drive wheel 307 to rotate. The drive wheel 307 drives the rotating ring 302 to rotate. At this time, the firing point of the laser emitter 5 can be adjusted, realizing the adjustment of the firing position while adjusting the distance. The self-locking mechanism prevents the angle drift caused by vibration or impact, ensuring the consistency of the landing point during continuous firing.

[0058] In this embodiment, the operator first places the laser target to be tested into the opposing target clamp 11. The opposing target clamp 11 automatically locks to ensure that the laser target does not shake. After the laser target is stably clamped, the operator inputs the test parameters into the PLC control panel 12, including the number of tilts, laser emission distance, and number of firing rings. The test command is then initiated in the PLC control panel 12, and the inner flip release assembly 10 automatically de-energizes and unlocks. The opposing target clamp 11 and the laser target tilt freely until they impact the horizontal platform 901 on the outer wall of the convex platform 9. The horizontal platform 901 simulates the impact surface of concrete or steel plate. At this time, the convex platform 9 and the horizontal platform 901 ensure structural stability, thereby simulating the fall that may occur in actual use. In the event of an impact, after the impact, the opposing target clamp 11 commands the chain-type centering and straightening assembly 8 to activate. The chain-type centering and straightening assembly 8 initially straightens the tilted target within the opposing target clamp 11, guiding the laser target back to the center position of the opposing target clamp 11, ensuring accurate reset of the target. Subsequently, the outer double-arm type flipping assembly 7 and the inner flipping release assembly 10 work together to precisely rotate the laser target back to its initial upright position, ensuring zero deviation in posture for each reset, until the laser target returns to its initial untilted state. During this process, the operator must observe the reset process to ensure that the laser target does not experience abnormal jamming or displacement. If any abnormality is found, the operation must be stopped immediately and adjustments or repairs made. To ensure smooth and accurate resetting, the double-sided belt traction assembly 6 is activated via the PLC control panel 12 after resetting the laser target. This assembly drives the support plate 2, the rack and pinion self-locking rotating assembly 3, the lead screw linear adjustment module 4, and the laser emitter 5 to move along the X-axis, adjusting the laser emitter 5's position. During this process, the operator can pre-adjust the laser emitter 5's position using the lead screw linear adjustment module 4 to change the linear distance between the laser emitter 5 and the center of the laser target, thus covering different areas of the target surface. During the process, the self-locking gear and rack assembly 3 also receives rotational power, causing the laser emitter 5 to adjust its position. After the position and distance are adjusted, the operator starts the laser emitter 5 through the PLC control panel 12 to perform a shooting test. The laser emitter 5 fires at the target according to the set number of rings, such as single shot or multiple shots in burst. The built-in sensor of the laser target feeds back the hit data to the PLC control panel 12 in real time, automatically determining whether the detection sensitivity, response speed and positioning accuracy are qualified, thereby evaluating the functional integrity of the target. The operator performs multiple repeated tests to ensure the reliability and repeatability of the data. After each test, the device performs a tilting and reset process, and the cycle is repeated to complete multiple rounds of testing.
