Description

A connecting rod 651 is hingedly arranged between the slider 65 and the rotating wheel 64. When the cross 62 rotates, the slider 65 is driven by centrifugal force to move to both sides (the movement mode can be referred to the authorization document CN110013668B).

[0027] A connecting mechanism 7 is provided between the sleeve rod 61 and the dual-axis motor 51, and the connecting mechanism 7 includes a transverse axis 2 71, which is provided on the mounting seat 31, and synchronous wheels are provided on the transverse axis 2 71 and the sleeve rod 61. A synchronous belt 73 is provided between the transverse axis 2 71 and the sleeve rod 61 through the synchronous wheels, and a bevel gear 72 is provided on the transverse axis 2 71 and the other end of the dual-axis motor 51, and the bevel gears 72 are engaged with each other, so that the dual-axis motor 51 drives the sleeve rod 61, so that the limiting frame 63 can respond immediately, and at the same time, the worm 1 511 at the other end of the dual-axis motor 51 cooperates with the worm wheel 1 522, and utilizes its deceleration characteristics, so that the sleeve rod 61 has a sufficient rotation speed on the premise that the guide seat 3 has a sufficient moving speed, to ensure that the slider 65 has sufficient centrifugal force.

[0028] An airbag 41 is provided on the inner side of the clamping tray 4, and an air pump (not shown in the figure) is provided on the clamping tray 4. A tray rack 42 is provided on the clamping tray 4, and a vertical rod 43 is provided on the tray rack 42. A connecting shaft 431 is provided on the vertical rod 43, and the vertical rod 43 is rotatably connected to the swing rod 321 through the connecting shaft 431. During the transportation of the guide seat 3, the air pump inflates the airbag 41, and the airbag 41 presses the display substrate inward, which can effectively clamp and fix the display substrate firmly, greatly improving the stability of the display substrate during transportation, and reducing the risk of damage due to shaking or falling.

[0029] A rotating mechanism 8 is arranged between the vertical rod 43 and the swing rod 321, and the rotating mechanism 8 includes a worm gear 81, which is arranged on the swing rod 321, and a worm wheel 82 is arranged on the connecting shaft 431. The worm gear 81 meshes with the worm wheel 82, and the self-locking characteristics of the transmission direction of the worm gear 81 and the worm wheel 82 can prevent the clamping tray 4 from accidentally rotating by itself, so as to ensure the stability of the clamping tray 4, an action gear 83 is arranged on the worm gear 81, and a C-shaped mounting frame 101 is arranged on the suspension frame 1, and a steering rack 10 is arranged on the C-shaped mounting frame 101, and the steering rack 10 can mesh with the action gear 83. When the guide seat 3 moves to the position of the steering rack 10, the steering rack 10 meshes with the action gear 83, driving the worm gear 81 to rotate, and then through the meshing with the worm wheel 82, the clamping tray 4 is rotated, and the rotation angle of the clamping tray 4 can be flexibly adjusted according to the length of the steering rack 10.

[0030] It should be noted that the working principle of the display substrate transfer clamping device for display screen production is as follows: the mounting seat 31 of the guide seat 3 is connected to the conductive rail 22 through the power receiving plate 311 to obtain electricity to power the dual-axis motor 51 and the clamping tray 4, and the dual-axis motor 51 of the driving mechanism 5 is installed on the mounting seat 31, and the worm 511 of the output shaft at one end thereof is engaged with the worm gear 522 of the horizontal axis 52 on the second guide wheel frame 34, driving the horizontal axis 52 to rotate, and then the guide seat 3 is moved on the track 2 through the engagement of the driving gear 521 with the rack 23 on the lower surface of the track 2, and the guide wheels on the first guide wheel frame 33 and the second guide wheel frame 34 are embedded in the guide grooves 21 on both sides of the track 2, so that the guide seat 3 always moves along the track of the suspension frame 1; the dual-axis motor The other end of 51 can drive the sleeve rod 61 to rotate through the synchronous belt 73. When the driving mechanism 5 rotates, the other end of the dual-axis motor 51 causes the sleeve rod 61 to rotate, and the cross 62 on the sleeve rod 61 rotates accordingly, so that the slider 65 moves to both sides under the action of centrifugal force, so that the slider 65 causes the rotating wheel 64 to move forward through the connecting rod 651 and compresses the spring 641, and the collar 631 follows the rotating wheel 64 to move forward synchronously and slide on the slide rod 633 until the limiting block 634 on the L-shaped plate 632 is separated from the teeth of the limiting gear 66, so that the swing rod 321 can rotate freely. In this way, during the movement of the guide seat 3, even in the rising track 2 part, the clamping tray 4 can still be vertical to the ground by gravity, thereby ensuring the stability of the display substrate transportation; The clamping tray 4 is provided with an air pump (not shown in the figure). During the transportation of the guide seat 3, the air pump inflates the airbag 41 to clamp and fix the display substrate. The clamping tray 4 is rotatably connected to the swing rod 321 through the connecting shaft 431 of the vertical rod 43. When the guide seat 3 moves to the position of the steering rack 10, the steering rack 10 engages with the action gear 83 on the worm gear 81, driving the worm gear 81 to rotate, and then the clamping tray 4 is rotated by engaging with the worm gear 82 on the connecting shaft 431. The rotation angle of the clamping tray 4 can be controlled according to the length of the steering rack 10, so as to meet the assembly angle requirements of each assembly station. When the guide seat 3 moves to the corresponding position of the electromagnetic plate 92 on the suspension frame 1, the magnetic control switch 9 senses and controls the dual-axis motor 51 to stop. The electromagnetic plate 92 is provided with an electromagnet, which is controlled by the staff. After the guide seat 3 stops moving, the magnetic control switch 9 on the guide seat 3 that is continuously transported from the rear senses the magnetic plate 91 on the front guide seat 3 and also enters a stop state, thereby preventing the rear guide seat 3 from pushing the front guide seat 3 away. When the dual-axis motor 51 stops, the limiting block 634 on the L-shaped plate 632 is again embedded between the teeth of the limiting gear 66 to limit the swing of the clamping tray 4, thereby facilitating the staff to directly assemble the clamping tray 4.

[0031] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
