[0007] Furthermore, the swing ball assembly includes: A sphere is fixedly connected to one end of a connecting rod 1, the other end of the connecting rod 1 is fixedly connected to a rotating ring, the rotating ring is also fixedly connected to one end of a connecting rod 2, and the rotating ring is rotatably connected to the lower end of the tray.

[0008] Furthermore, the longitudinal extrusion assembly includes: Slider 1, said slider 1 is rotatably connected to connecting rod 2, said slider 1 is slidably connected to the slide rail, both ends of the slide rail are slidably connected to two guide rods 1 respectively, said guide rod 1 is sleeved with a spring, the upper end of the guide rod 1 is fixedly connected to the lower end of the tray, and the lower end of the slide rail is fixedly connected to slider 2.

[0009] Furthermore, the compensating lock assembly includes: A guide rod 2, one end of which is fixedly connected to the lower end of the guide rod 1, the guide rod 2 is vertically arranged with the guide rod 1, the guide rod 2 is slidably connected with a trapezoidal block 1, a spring is sleeved on the guide rod 2, both sides of the trapezoidal block 1 are provided with inclined surfaces, the slider 2 is slidably connected to an inclined surface, and a slot is provided at the upper end of the trapezoidal block 1; and A locking rod, the lower end of which is fixedly connected to a trapezoidal block 2, which slides on the inclined plane, a spring is sleeved on the locking rod, the locking rod is slidably connected to the connecting block, and the connecting block is fixedly connected to the marking machine body.

[0010] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects: 1. After gear 2 stops rotating, the sphere swings under the action of inertia, which makes the tray have a force to swing forward. When the sphere swings, it drives connecting rod 2 connected to the rotating ring to rotate. When connecting rod 2 rotates, it drives slider 1 to slide on the slide rail. At the same time, the slide rail slides downward along guide rod 1, thereby driving slider 2 to slide downward together. Slider 2 slides downward, pushing trapezoidal block 1 to slide along guide rod 2 to the bottom of the lock rod, so that trapezoidal block 2 slides upward along the inclined surface, and the lock rod slides upward, thereby causing trapezoidal block 2 to slide into the slot. At this time, trapezoidal block 2 is stationary, the sphere stops swinging, and after pulling the lock rod upward, each component is reset under the action of the spring, thereby offsetting the displacement deviation of the tray caused by inertia, making the marking error of the airbag smaller.

[0011] 2. When gear one rotates, it meshes with gear two, causing gear two to rotate together, thereby driving the cam to rotate. Since the cam abuts against the top ball, the cam causes the top rod to slide when it rotates. Since the wedge block abuts against roller one, the top rod drives the wedge block to slide together when it slides, thereby causing the clamp to rotate. When the clamp rotates, one end of the clamp approaches gear two until it abuts against gear two, causing friction between one end of the clamp and gear two, causing gear two to stop rotating, thereby causing gear one to stop rotating, and the tray to stop moving. This design realizes integrated control from transmission to triggering to braking through a mechanical chain reaction, and has the advantages of simple structure, fast response, and convenient maintenance.

[0015] In order to enable those skilled in the art to better understand the solution of the present application, the following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0016] Reference Figure 1-2 As shown in FIG. 6 , a pallet positioning device for an airbag material marking machine comprises a marking machine body 1, a pallet 2 is slidably connected to the marking machine body 1, a movable self-locking mechanism 3 is provided below the pallet 2, and inertia compensation mechanisms 4 are provided on both sides below the pallet 2; The mobile self-locking mechanism 3 includes: A moving assembly 31, wherein the moving assembly 31 is fixedly connected to the marking machine body 1 and is located below the tray 2, and a primary positioning assembly 32 is rotatably connected to the marking machine body 1 of the moving assembly 31; The inertia compensation mechanism 4 includes: The swing ball assembly 41 is rotatably connected to the bottom of the tray 2. The lower end of the tray 2 is also fixedly connected to a longitudinal extrusion assembly 42. A compensation lock assembly 43 is provided on one side of the longitudinal extrusion assembly 42.

[0017] The cloth is sucked by the suction cup and adsorbed on the tray 2, and then the tray 2 is moved to the cutting position for cutting by the moving component 31. When the tray 2 moves to the cutting position, the tray 2 is positioned by the primary positioning component 32. Since the tray 2 has inertia, the swing ball component 41 moves with the tray 2 when the tray 2 moves. After the tray 2 moves to the cutting position, the position of the tray 2 may be offset due to inertia. After the tray 2 moves to the cutting position, the tray 2 stops moving, and the swing ball component 41 swings due to inertia, thereby compensating for the position offset of the tray 2. At the same time, the swing ball component 41 drives the longitudinal extrusion component 42 to work, so that the compensation lock component 43 limits the longitudinal extrusion component 42, thereby limiting the swing ball component 41.

[0018] Reference Figure 3 As shown, the tray 2 is slidably connected to the marking machine body 1; The mobile component 31 includes: The motor 311 is fixedly mounted on the marking machine body 1, a rack 312 is fixedly connected to the lower end of the tray 2, the rack 312 is meshed with a gear 1 313, the gear 1 313 is fixedly connected to a bevel gear 314 via a rotating shaft, the output end of the motor 311 is fixedly connected to another bevel gear 314, the two bevel gears 314 are meshed, and the rotating shaft is rotatably connected to the marking machine body 1.

[0019] The motor 311 works to drive a bevel gear 314 fixedly connected to the output end of the motor 311 to rotate, thereby driving the gear 1 313 to rotate. The gear 1 313 meshes with the rack 312, so that the rack 312 moves, thereby driving the tray 2 to slide on the marking machine body 1.

[0020] Reference Figure 4-5 As shown, the primary positioning component 32 includes: Gear 2 321, said gear 2 321 meshes with gear 1 313, said gear 2 321 is fixedly connected to the rotating shaft, the rotating shaft is rotatably connected to the marking machine body 1, the lower end of the rotating shaft is fixedly connected to the cam 322, said gear 2 321 is provided with clamping claws 323 on both sides, said clamping claws 323 are provided with connecting holes 1 3231 and connecting holes 2 3232, said connecting holes 2 3232 are rotatably connected with roller 1 324, said connecting holes 1 3231 and one of the torsion springs The first end of the torsion spring is fixedly connected to the marking machine body 1, the clamping jaw 323 is rotatably connected to the marking machine body 1 through a connecting hole 3231, the roller 324 abuts against one end of the push rod 325, the other end of the push rod 325 abuts against the cam 322, the push rod 325 is slidably connected to the marking machine body 1, one end of the push rod 325 is fixedly connected to a wedge block 3251, and the other end of the push rod 325 is fixedly connected to a top ball 3252.

[0021] When gear 1 313 rotates, it meshes with gear 2 321, so that gear 2 321 rotates together, thereby driving cam 322 to rotate. Since cam 322 abuts against top ball 3252, when cam 322 rotates, it causes push rod 325 to slide. Since wedge block 3251 abuts against roller 1 324, push rod 325 drives wedge block 3251 to slide together when sliding, thereby causing jaw 323 to rotate. When jaw 323 rotates, one end of jaw 323 approaches gear 2 321 until gear 2 321 abuts, so that one end of jaw 323 and gear 2 321 generate friction, causing gear 2 321 to stop rotating, thereby causing gear 1 313 to stop rotating, and tray 2 to stop moving.

[0025] When the connecting rod 2 414 rotates, it drives the sliding block 1 421 to slide on the sliding rail 422 , and at the same time, the sliding rail 422 slides downward along the guide rod 1 423 , thereby driving the sliding block 2 424 to slide downward together.

[0026] Reference Figure 9-12 As shown, the compensating lock assembly 43 includes: A second guide rod 431, one end of which is fixedly connected to the lower end of the first guide rod 423, the second guide rod 431 is vertically arranged with the first guide rod 423, a trapezoidal block 432 is slidably connected to the second guide rod 431, a spring is sleeved on the second guide rod 431, both sides of the trapezoidal block 432 are provided with inclined surfaces 4321, the second slider 424 is slidably connected to one of the inclined surfaces 4321, and a slot 4322 is provided at the upper end of the trapezoidal block 432; and The locking rod 433 has a trapezoidal block 4331 fixedly connected to its lower end.

[0027] The slider 424 slides downward, pushing the trapezoidal block 432 to slide along the guide rod 431 to the bottom of the locking rod 433, so that the trapezoidal block 4331 slides upward along the inclined surface 4321, and the locking rod 433 slides upward, thereby causing the trapezoidal block 4331 to slide into the slot 4322. At this time, the trapezoidal block 4331 is stationary, and the ball 411 stops swinging. After the locking rod is pulled upward, each component is reset under the action of the spring.
