DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0023] Please refer to the drawings attached Figure 1 -attached Figure 12 The embodiment of the present application provides a double-head ISOFIX force value detection device, which comprises an operation platform 1 and a double-head ISOFIX detection piece 14. The operation platform 1 is provided with a sliding detection mechanism 2, which is used for detecting the unlocking force and sliding force parameters of the double-head ISOFIX detection piece 14.

[0024] Specifically, the operation table 1 is the installation and bearing basis of the entire detection equipment, and provides a stable assembly platform for various detection mechanisms and auxiliary components. The overall structural design of the operation table 1 is adapted to the detection process requirements of the double-head ISOFIX detection piece 14, and ensures the coordination and stability of the actions of various mechanisms. The sliding detection mechanism 2 is used for detecting the unlocking force and sliding force parameters of the double-head ISOFIX detection piece 14, and is the core structure for realizing integrated detection of the unlocking force and the sliding force. Through the arrangement of the sliding detection mechanism 2 and the material pressing and blocking mechanism 5, the accurate collection of the two force value parameters can be completed without adjusting the position of the detection piece, and the position of the double-head ISOFIX detection piece 14 does not need to be adjusted additionally. That is, the unlocking force and the sliding force detection can be completed in the same detection process. The structural arrangement simplifies the operation process, avoids the cumbersome steps of separate transportation in the traditional detection, improves the detection convenience, and at the same time, the entire force value detection link does not need manual intervention, which reduces the human operation error.

[0025] The sliding detection mechanism 2 comprises an extension air cylinder 204, the output end of the extension air cylinder 204 is fixedly connected with a moving frame 205, the side surface of the moving frame 205 is fixedly connected with a clamping air cylinder 206, the output end of the clamping air cylinder 206 is fixedly connected with an unlocking shaft fixing block 208 through a clamping block 207, and the inner side wall of the clamping block 207 is fixedly installed with an unlocking force detector.

[0026] Specifically, the extension air cylinder 204 is one of the power output sources of the sliding detection mechanism 2, and is used to drive the subsequent components to move towards the unlocking shaft 23 of the double-head ISOFIX detection piece 14, so as to realize the accurate butt joint of the unlocking shaft fixing block 208 and the unlocking shaft 23. The moving frame 205 plays a role in component connection and force transmission. The arrangement of the moving frame 205 can ensure that the clamping air cylinder 206 and the unlocking shaft fixing block 208 are stably driven to move under the driving of the extension air cylinder 204, so as to avoid shaking or deviation during the movement. The clamping air cylinder 206 provides power for the clamping action of the unlocking shaft 23, and drives the clamping block 207 to realize the clamping and loosening of the unlocking shaft 23 through the extension and retraction of the clamping air cylinder 206. The action logic of the clamping air cylinder 206 is closely matched with the unlocking force detection process. When the unlocking shaft 23 enters the locking hole of the unlocking shaft fixing block 208, the clamping air cylinder 206 drives the clamping block 207 to clamp. The unlocking force detector installed on the inner side wall of the clamping block 207 can collect the unlocking force data in real time during the clamping process, without the need for additional detection steps. The unlocking and detection are performed synchronously, and the continuity of the detection process is optimized.

[0027] The double-head ISOFIX detection piece 14 is provided with a detection port 22 and an unlocking shaft 23, and the inside of the double-head ISOFIX detection piece 14 is provided with a lock hook structure 24. The lock hook structure 24 comprises a lock hook 25.

[0028] Specifically, the position and layout of the detection port 22 and the hook 25 ensure that the blocking shaft 306 of the push-pull force detection mechanism 3 can be accurately inserted into the detection port 22 and effectively contacted with the hook 25, providing a stable force basis for detection. The outer diameter size of the unlocking shaft 23 is accurately matched with the first unlocking shaft locking hole 209 of the unlocking shaft fixing block 208, ensuring the stable clamping and unlocking action of the sliding detection mechanism 2 on the unlocking shaft 23, and further ensuring the smooth development of the unlocking force and sliding force detection.

[0029] The upper surface of the operation table 1 is fixedly connected with a first electric sliding rail 201, a first sliding groove 202 is formed in the inside of the first electric sliding rail 201, a first sliding block 203 is slidably connected to the inner surface of the first sliding groove 202, the upper surface of the first sliding block 203 is fixedly connected with an extension air cylinder 204, and a sliding force detector is fixedly installed at the joint of the first sliding block 203 and a moving frame 205.

[0030] Specifically, the cooperation of the first electric sliding rail 201 and the first sliding block 203 provides accurate moving power and guidance for the sliding detection mechanism 2, and the running accuracy can ensure that the sliding detection mechanism 2 can accurately move to the detection position corresponding to the unlocking shaft 23 without manual assistance for positioning. The sliding force detector is installed at the joint of the first sliding block 203 and the moving frame 205, which is on the key path of force value transmission. When the first electric sliding rail 201 drives the first sliding block 203, the moving frame 205 and the unlocking shaft fixing block 208 to move, the detector can sense the sliding resistance in the moving process in real time, i.e. the sliding force of the double-head ISOFIX detection piece 14, realizing the synchronous sliding force detection and sliding action, avoiding additional detection steps, and further optimizing the coherence and efficiency of the detection process. The cooperation of the first electric sliding rail 201 and the first sliding block 203 is a common linear driving and guiding structure in the prior art, which will not be described in detail here.

[0031] The operation table 1 is provided with a push-pull force detection mechanism 3, which is used for detecting the push force, pull force and locking force parameters on both sides of the double-head ISOFIX detection piece 14. The push-pull force detection mechanism 3 comprises a push-pull air cylinder 304, a blocking shaft 306 fixedly connected to the output end of the push-pull air cylinder 304, a pull force and locking force detector fixedly installed at the connecting end of the blocking shaft 306 and the second moving block 305, a first upper and lower air cylinder 308 fixedly connected to the upper surface of the second moving block 305 through a first connecting block 307, a push block 310 fixedly connected to the output end of the first upper and lower air cylinder 308 through a second connecting block 309, and a push force detector fixedly installed on one side of the push block 310 facing the double-head ISOFIX detection piece 14.

[0032] Specifically, the push-pull force detection mechanism 3 is symmetrically arranged on the operation table 1, the push force detector is installed on the side of the push block 310 facing the detection piece, and can directly collect push force data when the push block 310 is driven by the push-pull cylinder 304 to apply pressure; the pull force and locking force detector is installed on the connecting end of the blocking shaft 306 and the second moving block 305, and can collect the locking force when the blocking shaft 306 is in contact with the locking hook 25, and collect the pull force when it is pulled back. The three force value detections do not need to adjust the position of the detection piece, and the whole process does not need manual intervention, realizing efficient detection of multi-dimensional force values of the two head parts in the same detection process, and simplifying the operation steps.

[0033] The inside of the unlocking shaft fixing block 208 is provided with a groove 210, the inner surface of the groove 210 is slidably connected with a first moving block 212, the inside of the first moving block 212 is provided with a first unlocking shaft locking hole 209, the inside of the unlocking shaft fixing block 208 is provided with a second unlocking shaft locking hole 213, and the inner surface of the unlocking shaft fixing block 208 is fixedly connected with the first moving block 212 through a spring 211.

[0034] Specifically, the groove 210, the first moving block 212 and the spring 211 constitute an elastic clamping structure, when the unlocking shaft 23 is inserted into the first unlocking shaft locking hole 209 and the second unlocking shaft locking hole 213, the elastic force of the spring 211 can assist the clamping cylinder 206 to enhance the clamping stability of the unlocking shaft 23, avoiding detection errors caused by the deviation of the unlocking shaft 23 during the unlocking process. At the same time, after the sliding force detection is completed, the springback force of the spring 211 can drive the first moving block 212 and the unlocking shaft 23 to quickly return to the original position without manual intervention, preparing for the next detection, and further improving the automation and continuity of the detection process.

[0035] The upper surface of the operation table 1 is fixedly connected with a second electric sliding rail 301, the inside of the second electric sliding rail 301 is provided with a second sliding groove 302, the inner surface of the second sliding groove 302 is slidably connected with a second sliding block 303, and the upper surface of the second sliding block 303 is fixedly connected with a push-pull cylinder 304.

[0036] Specifically, the cooperation of the second electric sliding rail 301 and the second sliding block 303 provides accurate movement guarantee for the push-pull force detection mechanism 3, and the running accuracy can ensure that the push-pull force detection mechanism 3 can accurately move to the corresponding detection position of the two head parts of the double-head ISOFIX detection piece 14 according to the detection requirement. When in use, the operator only needs to clamp and position the detection piece once, and then the push-pull force detection of the two head parts can be completed through the driving of the second electric sliding rail 301, avoiding the repeated taking, transporting and positioning calibration of the detection piece, shortening the total processing time of a single detection piece, and effectively improving the detection efficiency. The cooperation of the second electric sliding rail 301 and the second sliding block 303 is a common linear driving and guiding structure in the prior art, which will not be described in detail here.

[0037] A bracket 4 is fixedly connected to the upper surface of the operating table 1. A pressing and blocking mechanism 5 is provided on the bracket 4. The pressing and blocking mechanism 5 is used to stabilize and limit the double-headed ISOFIX test piece 14. The pressing and blocking mechanism 5 includes a second upper and lower cylinder 501. The output end of the second upper and lower cylinder 501 is fixedly connected to a pressing block 503 through a first fixing block 502. An auxiliary cylinder 504 is fixedly connected to the rear surface of the pressing block 503 through a connecting plate. An auxiliary fixing block 506 is fixedly connected to the output end of the auxiliary cylinder 504 through a third connecting block 505. An opening 507 is provided inside the pressing block 503. The lower end of the auxiliary fixing block 506 passes through the opening 507.

[0038] Specifically, the second upper and lower cylinders 501 drive the pressure block 503 to move downwards, and the auxiliary cylinder 504 drives the auxiliary fixing block 506 to move downwards. After the lower end of the auxiliary fixing block 506 passes through the opening 507, it enters the positioning hole 20. The two work together to form a double fixing structure, which can fix the double-headed ISOFIX test piece 14 in the test position, effectively preventing the double-headed ISOFIX test piece 14 from shifting position due to pushing, pulling and other forces during the test. The anti-slip design of the pressure block 503 and the precise engagement of the auxiliary fixing block 506 ensure the positional stability of the test piece in the whole process of the test, providing structural protection for the accuracy of various force values, while avoiding the positioning error and time waste caused by multiple loading and unloading in traditional tests.

[0039] The upper surface of the operating table 1 is fixedly connected to the testing table 11 by the second support frame 10. The testing table 11 has a second placement slot 12 inside, the second placement slot 12 has a testing frame 13 inside, and the testing frame 13 has a positioning hole 20 inside.

[0040] Specifically, the cooperation between the testing table 11, the second placement slot 12, and the testing frame 13 provides the foundation for the precise positioning of the dual-headed ISOFIX testing piece 14. The internal structure of the testing frame 13 is precisely adapted to the shape of the testing piece, and the positioning hole 20 can quickly engage with the auxiliary fixing block 506 to achieve precise positioning of the testing piece. The operator only needs to place the testing piece into the testing frame 13 to complete the initial positioning through the positioning hole 20, without the need for complicated adjustment operations, thus shortening the clamping time. At the same time, it ensures that key parts of the testing piece, such as the testing port 22 and the unlocking shaft 23, can be accurately aligned with the corresponding components of each testing mechanism.

[0041] The upper surface of the operating table 1 is fixedly connected to a placement rack 7 via a first support frame 6. The placement rack 7 has a first placement groove 8 inside, and an L-shaped fixing piece 9 is installed inside the first placement groove 8.

[0042] Specifically, the placement rack 7, the first placement slot 8, and the L-shaped fixing piece 9 provide a placement space for the double-headed ISOFIX test piece 14 that needs to be marked by the marking machine 17. After the force value test of the double-headed ISOFIX test piece 14 is completed, the double-headed ISOFIX test piece 14 is taken out and placed in the first placement slot 8. The L-shaped fixing piece 9 can accurately limit the test piece placed in the first placement slot 8 and prevent it from tipping over or shifting by fitting the shape structure of the test piece. After it is placed, the double-headed ISOFIX test piece 14 is marked by the marking machine 17 on the placement rack 7.

[0043] A detection protective cover 15 is fixedly connected to the upper surface of the operating table 1. A marking machine 17 is fixedly connected to the rear inner wall of the detection protective cover 15 through a connecting seat 16. A support seat 18 is fixedly connected to the lower surface of the operating table 1. A support leg 19 is fixedly connected to the lower surface of the support seat 18.

[0044] Specifically, the protective cover 15 is made of transparent material, which not only ensures the safety of operators and avoids the risk of parts accidentally popping out during the testing process, but also allows operators to easily observe the testing progress in real time. The marking machine 17 enables parallel operation of testing and marking. When a new set of test pieces is being tested for force, the marking machine 17 can mark the test pieces that have been tested in the previous set, marking key information such as the pass status and testing time. The support base 18 and support legs 19 provide stable support for the entire equipment, ensuring that the equipment will not shake during the operation of each mechanism, and providing a basic guarantee for the accuracy of the test data.

[0045] The upper surface of the bracket 4 is fixedly connected to the controller 21.

[0046] Specifically, the controller 21 integrates a PLC control system. All cylinders in this application, including the second lifting cylinder 501, auxiliary cylinder 504, extension cylinder 204, clamping cylinder 206, push-pull cylinder 304, and first lifting cylinder 308, as well as all electric slide rails, including the first electric slide rail 201 and second electric slide rail 301, the unlocking force detector, sliding force detector, pushing force detector, tension and locking force detector, and the marking machine 17, are electrically connected to the controller 21. The controller 21 outputs control signals through the PLC control system to precisely control the action sequence, operating rhythm, and opening / closing status of each component, achieving fully automated operation from clamping and fixing the test piece, multi-dimensional force value detection, and marking and storage. Operators can preset detection parameters, start and stop the detection process through the operation panel of controller 21, and view the various force value detection data, detection progress and product qualification status in real time through the display screen in front of controller 21. The operation is convenient and intuitive. It should be noted that the way controller 21 establishes electrical connection with each cylinder, electric slide rail, force value detector and marking machine 17 and controls their opening and closing, as well as the marking function of marking machine 17 itself, are all existing technologies. Furthermore, the thrust detection function of the thrust detector, the unlocking force detection function of the unlocking force detector, the sliding force detection function of the sliding force detector, and the locking force detection function and tension detection function of the locking force detector are all existing technologies.

[0047] Working principle: When using this device, place the dual-headed ISOFIX test piece 14 to be tested in the testing position of the testing frame 13. Activate the second up-and-down cylinder 501 to move the first fixing block 502 and the pressing block 503 downwards. Activate the auxiliary cylinder 504 to move the third connecting block 505 and the auxiliary fixing block 506 downwards to fix the dual-headed ISOFIX test piece 14. Activate the left-side second electric slide rail 301, and the second slider 303 slides to the designated position in the second slide groove 302. Activate the push-pull cylinder 304 to move the second moving block 305 and the push block 310. The push block 310 presses down on the left side of the dual-headed ISOFIX test piece 14. The thrust of the dual-headed ISOFIX test piece 14 can be detected by the thrust detector. After the test is completed, activate the push-pull cylinder 304 to move the push block 310 back. Activate the first up-and-down cylinder 308 to move the second connecting block 305... 9. Push block 310 moves upward, exposing the blocking shaft 306 on one side of the second moving block 305. The push-pull cylinder 304 is activated to drive the second moving block 305 and the blocking shaft 306 to move. The blocking shaft 306 enters the detection port 22 of the double-headed ISOFIX detector 14 and contacts the locking hook 25 to form a lock. After the locking force of the double-headed ISOFIX detector 14 is detected by the locking force detector, the push-pull cylinder 304 is activated to extend and move back, driving the second moving block 305 and the blocking shaft 306 to pull back. At this time, the locking hook 25 and the blocking shaft 306 remain locked. The blocking shaft 306 applies a pulling force to the double-headed ISOFIX detector 14 through the locking hook 25. Then, the pulling force data is collected by the locking force detector to complete the pulling force detection of the double-headed ISOFIX detector 14. After the detection is completed, the left second electric slide rail 301 is activated, and the second slider 303 slides back to its original position in the second slide groove 302.

[0048] Start the second electric slide rail 301 on the right side, and the second slider 303 slides to the designated position in the second slide groove 302. Repeat the above operation to test the push force, pull force and locking force on the right side of the double-headed ISOFIX test piece 14. After the test is completed, start the second electric slide rail 301 on the right side to drive the second slider 303 to reset.

[0049] The first electric slide rails 201 are started simultaneously, and the first slider 203 moves to the designated position. The extension cylinder 204 is started to move the moving frame 205 and the unlocking shaft fixing block 208. The unlocking shaft 23 enters the unlocking shaft fixing block 208. The clamping cylinder 206 is started to clamp the clamping block 207, so that the unlocking shaft 23 on the double-headed ISOFIX detection element 14 is clamped. The unlocking force is detected by the unlocking force detector at the same time. The first electric slide rail 201 is started to move the first slider 203 and the double-headed ISOFIX detection element 14. The sliding force detector detects the sliding force of the double-headed ISOFIX detection element 14. The clamping cylinder 206 is started to release and reset the clamping block 207. The extension cylinder 204 and the first electric slide rails 201 are started in sequence to reset the first slider 203.
