Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of visual light source vibration reduction applications, and in particular relates to a full-spectrum machine vision light source module. Background Art
[0002] Full-spectrum machine vision light source module: This module integrates multiple wavelengths of light, covering the visible to near-infrared spectrum. Designed specifically for machine vision systems, it precisely controls spectral distribution to meet the high-resolution recognition requirements for surface features and material properties in scenarios such as industrial inspection and optical imaging.
[0003] During the specific implementation process, there is a problem of horizontal displacement offset between the visual light source module and the slide rail: that is, when the motor starts, the torque rises rapidly, driving the visual light source module to accelerate, and the inertial force causes an instantaneous relative displacement between the visual light source module and the slide rail; during an emergency stop, the braking torque forces the visual light source module to stop suddenly, and the inertial effect causes the visual light source module to continue moving. If the braking force is too large, it will further cause the visual light source module to "rush forward" or "move backward"; the dynamic impact breaks the stable contact state between the visual light source module and the slide rail, and when there is a gap between the visual light source module and the slide rail, the impact will continuously amplify the displacement error, resulting in inaccurate positioning of the light source module;
[0004] At the same time, motor torque fluctuations (such as step angle error of stepper motors and current fluctuations of servo motors) can cause uneven drive acceleration, causing the motion trajectory of the visual light source module to deviate from the ideal path, resulting in horizontal offset.
[0005] In addition, airflow impacts the light source module or slide rail, generating additional force. This, combined with the opening and closing vibration (the core mechanism that causes the decrease in fit due to vibration: gap method effect, failure of rigid connection, and disruption of dynamic balance), results in horizontal offset. Temperature changes cause the slide rail or visual light source module material to expand and contract. If expansion gaps are not reserved during installation, displacement may occur due to stress deformation.
[0006] The adverse effects of displacement of the visual light source module during actual use are explained using the example of PCB hotbar online AOI visual inspection:
[0007] a. Illumination uniformity deviation: The horizontal offset of the light source module causes uneven distribution of light intensity on the PCB. The image captured by the AOI camera appears partially too bright or too dark, affecting the recognition accuracy of pads and circuit edges.
[0008] b. Image distortion: The offset of the light source position changes the angle of the optical path, causing geometric distortion of features on the PCB (such as solder balls and traces) in the image. The detection algorithm may mistakenly identify normal features as defects (such as cold solder joints and short circuits).
[0009] c. Pixel-level positioning failure: AOI usually requires detection accuracy to be within ±10μm. If the light source offset caused by vibration exceeds this threshold, the pixel coordinates of the feature points in the image will shift, affecting the accuracy of size measurement and defect comparison.

[0041] The toothed pulley is clamped and mounted on the outer walls of both ends of the lead screw and the guide rod;
[0042] The toothed belt is clamped and installed between the toothed pulleys.
[0043] A method for adaptively adjusting the coordination degree of a visual light source under the long-term action of sudden opening and closing is implemented by using the above-mentioned full-spectrum machine vision light source module. The specific steps are as follows:
[0044] S1: First, the relative motion state difference between the mountain pass seat and the U-shaped frame at the moment of opening and closing causes the wedge plate and the rod to interact to varying degrees, thereby changing the angle difference between the port ring and the initial state. Afterwards, the threaded fit between the screw and the angle sleeve causes the angle sleeve to synchronously control the electrode column to move toward the double-ear seat through the staggered plate under the support and guidance of the U-shaped frame until the electrode column contacts the electrode sheet.
[0045] During this process, the rotation angle of the tooth plate is limited by the limit column. That is, when the port ring bin moves away from the wedge plate under the push of the bar, the limit column limits the rotation direction of the tooth plate, prompting the tooth plate to engage with the tooth mouth of the gear ring, controlling the angle ring to drive the screw rod to rotate in one direction, and through the restoring action of the torsion spring, when the wedge plate separates from the bar, it drives the bar to move to the initial position;
[0046] S2: Then, a servo motor controls the rotation of one of the lead screws. Under the action of the toothed belt drive, the toothed pulleys at different positions drive the lead screws and guide rods at different positions to rotate to a specified angle. At the same time, under the dual action of the lead screw drive and the guide rod guide, the yam blocks move towards each other, adaptively adjusting the vertical distance between the relative yam blocks, reducing the amplitude of the telescopic spring, and improving the real-time matching accuracy between the yam blocks and the horizontal slide rail.
[0047] S3: Finally, the nonlinear repeated vertical "jumps" between the ball head and the end face of the horizontal slide rail change the relative motion state between the spring rubber plug and the ring mouth. At the same time, the external gas is compressed through the one-way valve to between the double-headed elastic gas plug and the one-way valve through the air port. Under the reverse action of the gas, the single-head telescopic piston controls the movement of the ball toward the horizontal slide rail, gradually increasing the degree of interaction between the ball and the horizontal slide rail, providing vertical force components, assisting the horizontal feedback unit, and further stabilizing the clamping fit accuracy between the Yamaguchi seat and the horizontal slide rail.
[0048] The present invention has the following beneficial effects:
[0049] 1. The present invention achieves an equal limit contact relationship between the electrode column and the electrode sheet through "single maximum stroke interaction" or "nonlinear cumulative interaction" between the wedge plate and the bar, which serves as the starting signal for the servo motor. Thereafter, the combined rotation of the lead screw and guide rod causes the mountain pass seats to move toward each other to a specified position until the amplitude of the wedge plate generated by external impact or the opening and closing of the horizontal slide rail is insufficient to cause interaction between the wedge plate and the bar. This cycle is repeated in real time to adjust the clamping fit accuracy between the opposing mountain pass seats and the horizontal slide rail, fully ensuring the stability of the visual light source module at the opening and closing moments, reducing displacement offset, improving illumination uniformity, and improving image distortion, thereby ensuring the accuracy of measurement and defect comparison.
[0050] 2. The present invention uses the nonlinear resonance generated by the ball head and the horizontal slide rail during normal operation to prompt the spring rubber plug to continuously reciprocate along the axis of the ring mouth under the reverse force of the ball head. During the reciprocating motion of the spring rubber plug, the spring rubber plug makes staggered contact with the air port, and the external gas is gradually filled into the space between the one-way valve and the double-headed elastic piston through the one-way valve. After that, under the reverse force of the gas, the single-headed telescopic piston gradiently strengthens the degree of interaction between the ball and the end face of the horizontal slide rail, provides a vertical force component, assists the horizontal feedback unit, and further stabilizes the clamping and fitting accuracy between the mountain pass seat and the horizontal slide rail.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0072] It should be noted that the terms “vertical”, “horizontal”, “left”, “right” and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.
[0073] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0075] Reference Figure 3 、、 Figure 4 、 Figure 7 and Figure 8 It can be seen that the horizontal feedback unit 2 includes: two mountain pass seats 21, which are symmetrically mounted on the end surfaces of the horizontal slide rail 1 in a sliding and snap-fitting manner; four U-shaped side frames 22, which are symmetrically mounted on the corner ends of the outer wall of the mountain pass seats 21 in a sliding and snap-fitting manner; a double-ear seat 23, which is snap-fitted and mounted in the middle position of the horizontal section of the U-shaped side frame 22; a screw rod 24, which is rotatably mounted in the middle position of the double-ear seat 23 away from the mountain pass seat 21; in addition, snake grooves with opposite rotation directions are opened at both ends of the outer wall of the double-ear seat 23;

There are two staggered plates 212 in the same group. The two staggered plates 212 are vertically distributed. In addition, the staggered plates 212 are slidably mounted on the inner wall of the U-side frame 22. The staggered plate 212 parallel to the axis of the screw rod 24 is mounted on the end face of the middle position of the U-side frame 22. The electrode column 213 is installed on the end face of the staggered plate 212 near the middle position of the U-side frame 22. An ear plate 214 is symmetrically mounted on the outer wall of one side of the ring 26. A coupling shaft 215 is mounted between the two ear plates 214 for mutual rotation. A tooth plate 216 cooperating with the gear ring 28 is mounted on the outer wall of the coupling shaft 215. A limiting column is provided on one side of the tooth plate 216. A coil spring 217 is mounted between the tooth plate 216 and the ear plate 214. A bar 218 is mounted on the middle position of the outer wall of the port ring 27 near the middle position of the mountain pass seat 21.
[0078] Reference Figure 5 、 Figure 7 ,and Figure 8 It can be seen that the four corners of the mountain pass seat 21 are all provided with an inner mold bin 221, and the inner mold bin 221 is provided with a T-section column 222 that is slidably clamped and installed with the mountain pass seat 21. The end of the T-section column 222 away from the horizontal slide rail 1 is clamped and installed with a wedge plate 223 that cooperates with the bar 218. The opposite surfaces of the two T-section columns 222 are symmetrically clamped and installed with a polar position column 224 that is slidably clamped and installed with the mountain pass seat 21. A telescopic spring 225 is provided between the two mountain pass seats 21 and is sleeved on the outer wall of the polar position column 224.

The two opposite elastic columns 226 are clamped and installed with a corner plate 227 that is slidably clamped and installed with the mountain pass seat 21. The middle position of the horizontal section of the U-side frame 22 away from the horizontal slide rail 1 is plugged and installed with an electrode sheet 228 that cooperates with the electrode column 213.
[0079] Reference Figure 6 and Figure 7It can be seen that the outer wall of the mountain pass seat 21 is symmetrically clamped and installed with brackets 231, and there are four of them. In addition, the brackets 231 are symmetrical with each other, and the two opposite brackets 231 are slidingly clamped and installed with pillars 232. The outer wall of the vertical section of the U-side frame 22 is symmetrically clamped and installed with wall panels 233 that are slidingly clamped and installed with the pillars 232. A return spring 234 mounted on the outer wall of the pillar 232 is clamped and installed between the wall panels 233 and the brackets 231.
[0080] Monitoring process of horizontal (compared to the direction of gravity) clamping fit between the mountain pass seat 21 and the horizontal slide rail 1 under time effect:
[0081] Take the amplitude of multiple nonlinear frequencies (between the horizontal slide rail 1 and the mountain pass seat 21) as an example:
[0082] Precondition: When the base 21 is subjected to external shock vibration, equipment vibration, or the horizontal slide rail 1 is opened or closed, there is a relative motion difference between the base 21 and the U-shaped frame 22.
[0083] First, affected by the synchronization between the mountain pass seat 21 and the U-shaped frame 22, the wedge plate 223 and the bar 218 synchronously generate a relative motion difference (in the specific implementation process, due to the overlapping diversity between external vibrations or the vibrations of the equipment itself, the overall vibration of the mountain pass seat 21 and the horizontal slide rail 1 is nonlinear). Under the squeezing action of the bar 218, the port ring 27 controls the gear ring 28 to rotate in the positive direction (with the rotation of the bar 218 away from the wedge plate 223 as the positive reference). At this time, the screw rod 24 produces different degrees of angular rotation under the joint support and guidance of the support plate 29 and the double-ear seat 23;
[0084] During this process, when the gear ring 28 and the port ring magazine 27 rotate synchronously, they continuously generate an engaging movement with the tooth plate 216 (in the specific implementation, the limit column is set on the side close to the wedge plate 223, so that when the tooth plate 216 and the tooth mouth of the gear ring 28 are engaged and rotated, the limit column limits the functional layout of the unidirectional rotation of the tooth plate 216), and the torsion spring 211 itself restores the force to ensure that when the wedge plate 223 and the bar 218 are in a separated (intermittent) state, the port ring magazine 27 can drive the bar 218 moves to the initial position (when the port ring magazine 27 drives the gear ring 28 to rotate in the opposite direction, the engagement between the teeth of the gear ring 28 and the gear plate 216 becomes "loose", that is, the limit column no longer limits the rotation of the gear plate 216, and the elastic restoring force of the coil spring 217 itself causes the gear plate 216 to separate from the teeth of the gear ring 28. At this time, the gear plate 216 can return to the initial state under the support of the connecting shaft 215 (the ear plate 214 provides a stable support environment for the connecting shaft 215));
[0085] Next, during the rotation of the screw rod 24 (under the influence of the synchronization of the movement between the angle ring 26 and the tooth plate 216), the two (same group) angle sleeves 25 are synchronously controlled to move toward each other by a specified distance (directly affected by the degree of interaction between the wedge plate 223 and the bar 218) until the electrode column 213 and the electrode sheet 228 are in contact (at this point, the electrode column 213 and the electrode sheet 228 are electrically connected. In specific implementation, the physical contact signal between the two can be converted into an electrical signal through an external PLC control system as an external judgment signal). During this process, the U-side frame 22 supports and guides the staggered plate 212, which promotes the stable movement of the angle sleeves 25 under the action of the screw rod 24.
[0086] Finally, the vertical distance between the two oppositely spaced yokes 21 is adjusted by the adjustment unit 4 (for the detailed adjustment process, refer to the subsequent adjustment unit 4). At this time, a relative motion difference is generated between the yokes 21 and the U-shaped frame 22. The support plate 29, supported and guided by the pillar 232, compresses the return spring 234 to a certain deformation.
[0087] The feasibility of generating the relative motion difference between the aforementioned yoke 21 and the U-shaped side frame 22: Since the U-shaped side frame 22 and the yoke 21 are in a sliding engagement state, and are also affected by the elastic coefficient of the return spring 234, a relative motion difference will inevitably occur between the yoke 21 and the U-shaped side frame 22 when the yoke 21 suddenly opens and closes. (In specific implementation, the relative motion between the yoke 21 and the U-shaped side frame 22 can be further ensured by externally calculating factors such as the friction force and weight distribution between the two.)
[0088] Further guarantee process of relative position hysteresis of wedge plate 223 (in specific implementation) relative to bar 218:
[0089] After adjustment by the adjustment unit 4, the amplitude reduction process between the two oppositely distributed mountain pass seats 21 and the horizontal slide rail 1 is as follows:
[0090] When the seat 21 is suddenly opened or closed, the T-section column 222 tends to move relative to the seat 21. At this time, the friction between the T-section column 222 and the inner mold bin 221, and the friction between the angle plate 227 and the seat 21, slows down the movement synchronization between the wedge plate 223 and the seat 21, improves the contact hysteresis between the wedge plate 223 and the rod 218, and further reduces the relative amplitude between the seats 21 by synchronously compressing the telescopic spring 225 and the elastic column 226, thus avoiding a relative resonance state (when the two seats 21 move toward each other).
[0091] It is hereby explained that when a single and sufficient relative contact movement occurs between the wedge plate 223 and the rod 218, the engagement between the gear ring 28 and the gear plate 216 is sufficient to cause the screw 24 to rotate to a specified angle, driving the angle sleeve 25 to control the electrode column 213 to move to the electrode plate 228 position in one go.
[0092] Reference Figure 3 and Figure 4 It can be seen that the two mountain pass seats 21 are commonly clamped and installed with a hanging platform 241 on the end surface close to the base 12. The end surface of the hanging platform 241 close to the base 12 is symmetrically clamped and installed with a pillar damper 242. The two pillar dampers 242 are commonly clamped and installed with a full-spectrum visual light source 243 on the end away from the hanging platform 241.
[0093] Reference Figure 1 and Figure 2 It can be seen that a cabinet 11 is provided in the outer space of the horizontal slide rail 1, and a base 12 is mounted on the end of the cabinet 11 away from the horizontal slide rail 1, and a top cover 13 is mounted on the end of the cabinet 11 away from the base 12, and a warning light 14 is installed in a corner of the end face of the top cover 13 away from the base 12.

Side windows 18 are symmetrically distributed on the outer wall of the cabinet 11, and a belt conveyor rail 19 is mounted in the middle position of the end face of the middle platform 17 away from the base 12 through a mounting seat.
[0094] Reference Figure 4 、 Figure 5 and Figure 6 It can be seen that the adjustment unit 4 includes: two opposite mountain seats 21 are symmetrically plugged into and installed with screws 41 threadedly fitted with the mountain seats 21 at diagonal positions on one side, and two opposite mountain seats 21 are symmetrically plugged into and installed with guide rods 42 slidingly fitted with the mountain seats 21 at diagonal positions on the other side. A motor frame 43 is fitted into a corner of the outer wall of one mountain seat 21, and a servo motor 44 is fitted into the outer wall of the horizontal end of the motor frame 43, and the servo motor 44 is fitted into and fitted with the screws 41 at the corresponding position. Toothed pulleys 45 are fitted into and installed at both ends of the outer walls of the screws 41 and the guide rods 42, and a toothed belt 46 is fitted into and installed between the toothed pulleys 45.
[0095] The simple process of detecting the object with full spectrum visual light source 243:
[0096] The belt conveyor track 19 is supported by the middle platform 17 (the side windows 18 ensure the feasibility of the detection process and reduce the overlap between the external light source and the full-spectrum visual light source 243). The object to be detected is gradually moved to the lower end of the full-spectrum visual light source 243 (positively distributed) through the external conveyor plate. In specific implementation, the belt in the belt conveyor track 19 can be driven to rotate by an external motor.
[0097] Under the support and guidance of the angle frame 16, the horizontal slide rail 1 drives the mountain pass seat 21 to move stably. Under the synchronous action of the mountain pass seat 21, the hanging platform 241 controls the pillar damper 242 to drive the full-spectrum visual light source 243 to move to the specified position. In specific implementation, axially distributed pillar dampers 242 can be installed at appropriate positions to further reduce the displacement of the full-spectrum visual light source 243 during movement.
[0098] Base 12, cabinet 11, top cover 13: provide a stable operating environment for the horizontal feedback unit 2, vertical feedback unit 3, and adjustment unit 4, reducing the impact of external airflow, temperature, or vibration factors;
[0099] Corner frame 16: provides a stable and secure support environment for the middle platform 17, while strengthening the cabinet 11 body, improving its impact resistance to the external environment and improving transportation safety;
[0100] Cabinet door 15: It is convenient for the tester to take out the parts and observe the specific test process, thus improving the safety of the test;
[0101] Warning light 14: On the one hand, it can remind external users of the safety of the operation; on the other hand, it can serve as a signal that the aforementioned electrode column 213 and electrode sheet 228 are in contact, reminding the user to perform corresponding maintenance and replacement of the mountain pass seat 21 or the horizontal slide rail 1 body;
[0102] The relative adjustment process of the screw 41 to the position of the mountain pass seat 21:
[0103] Precondition: The electrode column 213 is in contact with the electrode sheet 228;
[0104] A servo motor 44 (a motor frame 43 provides a stable operating environment for the servo motor 44) drives one of the lead screws 41 to rotate (in specific implementation, the spiral grooves distributed on the outer walls of the two ends of the lead screw 41 rotate in opposite directions). Under the support and guidance of the guide rod 42, the mountain pass seat 21 controls the two relatively distributed mountain pass seats 21 to move toward each other to a specified distance until there is no relative movement between the wedge plate 223 and the same rod 218. During this process, the transmission action of the toothed belt 46 prompts the toothed belt pulleys 45 at different positions to drive the lead screw 41 or guide rod 42 at the corresponding position to rotate.
[0105] Reference Figure 5、 Figure 10 and Figure 11 It can be seen that the vertical feedback unit 3 includes: a decorative panel 31, which is symmetrically distributed on the outside of the horizontal slide rail 1, and the decorative panel 31 is slidably snap-fitted with the mountain pass seat 21; a U-shaped tube 32, which is plugged and installed in the middle position of the decorative panel 31; two rings 33, which are symmetrically snap-fitted on the inner wall of one end of the U-shaped tube 32; a spring plug 34, which is slidably snap-fitted and installed at the axis of the ring 33; in addition, the spring plug 34 is away from the horizontal slide rail. 1 is fitted with the inner wall of the U-shaped tube 32; the ball head 35 is rollingly mounted on the end of the spring rubber plug 34 near the horizontal slide rail 1; the one-way valve 36 is clamped and mounted in the middle of the arc section of the U-shaped tube 32; there are two washers 37, which are symmetrically clamped and mounted in the middle of the inner wall of the other end of the U-shaped tube 32; the double-headed elastic air plug 38 is slidingly clamped and mounted at the axis of the washer 37, and the double-headed elastic air plug 38 is fitted with the inner wall of the U-shaped tube 32;
[0106] Reference Figure 10 and Figure 11 It can be seen that the inner wall of the tube end on the other side of the U-face tube 32 is symmetrically clamped and installed with a sealing ring 311, and a single-head telescopic piston 312 that is fitted with the inner wall of the U-face tube 32 is slidably clamped between the two sealing rings 311. The outer wall of the horizontal slide rail 1 is provided with symmetrically distributed grooves 313, and the single-head telescopic piston 312 is clamped and installed with a ball 314 that matches the groove 313 at the end away from the gasket 37. An air port 315 is provided on the outer wall of the tube end of the U-face tube 32 close to the ring mouth 33, and an angle valve 316 is inserted and installed in the middle position of the outer wall of the tube end on the other side of the U-face tube 32.
[0107] The ball 314 provides a vertical force component to the end surface of the horizontal slide rail 1 (or the mountain seat 21):
[0108] Precondition: During the specific implementation process, the ball head 35 and the horizontal slide rail 1 continuously "jump" relative to each other (under the influence of vibration factors);
[0109] First, under the reverse action of the ball head 35, the spring plug 34 continuously reciprocates along the axis of the ring opening 33 (the ring opening 33 provides a further stable support environment for the spring plug 34) (and the degree of back and forth reciprocating motion is different). During this process, the spring plug 34 continuously produces an interlaced motion with the air port 315. External gas flows through the air port 315 to the area between the spring plug 34 and the one-way valve 36 (due to the principle of negative pressure). Under the compression of the spring plug 34, the gas flows through the one-way valve 36 (the one-way valve 36 only allows gas to flow from the spring plug 34 end to the double-ended elastic air plug 38 end) to the other end of the U-surface tube 32;
[0110] Then, as the gas between the double-headed elastic gas plug 38 and the one-way valve 36 gradually increases, the double-headed elastic gas plug 38 compresses the oil under the combined action of the reverse force of the gas and the guidance of the gasket 37 (in specific implementation, the oil can be filled between the double-headed elastic gas plug 38 and the single-headed telescopic piston 312). Under the squeeze of the oil, the single-headed telescopic piston 312 drives the ball 314 to move toward the horizontal slide rail 1, thereby strengthening the interaction force between the ball 314 and the horizontal slide rail 1, providing a vertical component of force to the mountain pass seat 21, and further improving the clamping stability between the mountain pass seat 21 and the horizontal slide rail 1.
[0111] Finally, the gas between the double-ended elastic gas plug 38 and the one-way valve 36 is released through the angle valve 316, thereby causing the spring rubber plug 34, the double-ended elastic gas plug 38 and the single-ended telescopic piston 312 to return to their initial states.
[0112] The present invention provides a full-spectrum machine vision light source module having the following operating principles: First, the relative motion state difference between the mountain pass seat 21 and the U-shaped side frame 22 at the moment of opening and closing is used to promote different degrees of interaction between the wedge plate 223 and the bar 218, thereby changing the angle difference between the port ring 27 and the initial state. Then, through the threaded fit between the screw rod 24 and the angle sleeve 25, the angle sleeve 25, under the support and guidance of the U-shaped side frame 22, synchronously controls the electrode column 213 to move toward the double-ear seat 23 through the staggered plate 212 until the electrode column 213 contacts the electrode sheet 228.
[0113] During this process, the rotation angle of the tooth plate 216 is limited by the limiting column. That is, when the port ring magazine 27 moves away from the wedge plate 223 under the push of the bar 218, the limiting column limits the rotation direction of the tooth plate 216, causing the tooth plate 216 to engage with the teeth of the gear ring 28, controlling the angle ring 26 to drive the screw rod 24 to rotate in one direction. Moreover, due to the restoring action of the torsion spring 211, when the wedge plate 223 separates from the bar 218, the bar 218 is driven to move to the initial position.
[0114] Step 2: Then, the servo motor 44 controls the rotation of one of the lead screws 41, and under the transmission action of the toothed belt 46, the toothed pulleys 45 at different positions drive the lead screws 41 and guide rods 42 at different positions to rotate a specified angle. At the same time, under the dual action of the drive of the lead screw 41 and the guidance of the guide rod 42, the mountain pass seat 21 moves toward each other, adaptively adjusting the vertical distance between the relative mountain pass seat 21, reducing the amplitude of the telescopic spring 225, and improving the real-time matching accuracy between the mountain pass seat 21 and the horizontal slide rail 1;
[0115] Step 3: Finally, the nonlinear repeated vertical "jumps" between the ball head 35 and the end face of the horizontal slide rail 1 change the relative motion state between the spring rubber plug 34 and the ring opening 33. At the same time, the external gas is compressed through the one-way valve 36 through the air port 315 to between the double-headed elastic air plug 38 and the one-way valve 36. Under the reverse action of the gas, the single-headed telescopic piston 312 controls the ball 314 to move toward the horizontal slide rail 1, gradually increasing the degree of interaction between the ball 314 and the horizontal slide rail 1, providing a vertical component of force, assisting the horizontal feedback unit 2, and further stabilizing the clamping and fitting accuracy between the mountain pass seat 21 and the horizontal slide rail 1.
