[0019] like Figure 1-4 As shown, the present invention provides an automatic adjustment device for a support and limit block of a display fixture. The fixture 1 is positioned on a collector plate 2, which is transported along a conveyor line 3 to an adjustment mechanism. Positioning blocks 4 are provided at the front and rear ends of the conveyor line 3 to facilitate isolation of the collector plate 2 for independent placement. A lateral positioning cylinder 5 is provided on one side of the center of the adjustment mechanism of the conveyor line 3. The lateral positioning cylinder 5 is used to push the collector plate 2 against the other side of the conveyor line 3 for precise positioning.

[0020] The tooling fixture 1 has a slidable (L-shaped clamp) limit block 11 and a (U-shaped) support block 12. The limit block 11 is connected to the upper end cross bar of the tooling fixture 1 through a guide rail pair. The rear end of the limit block 11 is connected to an inner button-type snap-fit ​​mechanism 13. The inner button-type snap-fit ​​mechanism 13 cooperates with the rear serrated guide bar of the upper end cross bar to realize the left and right position positioning of the limit block 11; the support block 12 is connected to the lower end cross bar of the tooling fixture 1 through a guide rail pair. The rear end of the support block 12 is connected to an outer button-type snap-fit ​​mechanism 14. The outer button-type snap-fit ​​mechanism 14 cooperates with the rear serrated guide bar of the lower end cross bar to realize the left and right position positioning of the support block 12.

[0021] The adjustment mechanism includes an inner adjustment mechanism 6 located on the inner side of the conveyor line body 3 and an outer adjustment mechanism 7 located on the outer side of the conveyor line body 3. The inner adjustment mechanism 6 is used to adjust the left and right positions of the upper limit block 11 of the tooling fixture 1, and the outer adjustment mechanism 7 is used to adjust the left and right positions of the support block 12 on the tooling fixture 1.

[0022] The inner adjustment mechanism 6 includes an inner bottom frame 61, to which is fixed an inner servo module 62 for precise positioning. A first inner chassis 63 is connected to the inner servo module 62, which can drive the first inner chassis 63 to move left and right. An inner telescopic cylinder 64 is fixed above the first inner chassis 63, and a second inner chassis 65 is located above the inner telescopic cylinder 64. The second inner chassis 65 is connected to the top of the first inner chassis 63 and to the inner telescopic cylinder 64 via a guide rail pair. A tilted fixing plate is located above the second inner chassis 65, to which is fixed an inner clamp cylinder 66 and an inner photoelectric sensor switch 67. The inner photoelectric sensor switch 67 is used to determine the position of the limit block 11. The inner clamp cylinder 66 is used to clamp the inner button-type snap mechanism 13 at the rear end of the limit block 11, and the inner servo module 62 is then moved to adjust the left and right position of the limit block 11.

[0023] The outer adjustment mechanism 7 includes an outer bottom frame 71, on which is fixed an outer servo module 72 for achieving precise positioning. The outer servo module 72 is connected to an outer chassis 73, and the outer servo module 72 can drive the outer chassis 73 to move left and right; an outer photoelectric sensor switch 74 and an outer telescopic cylinder 75 are fixed above the outer chassis 73, and the head of the outer telescopic cylinder 75 is fixed with a slot for clamping the support block 12 on the tooling fixture for easy left and right movement; a hook clamp module 76 is connected below the slot, including a reverse hook pressure piece 761, a hook telescopic cylinder 762, a connecting mechanism 763 and a telescopic guide rail 764, the hook telescopic cylinder 762 is telescoped and drives the reverse hook pressure piece 761 to stand up or lie down through the connecting mechanism 763, and when the reverse hook pressure piece 761 stands up, it is used to press the outer button-type buckle mechanism 14. The outer photoelectric sensor switch 74 is used to determine the position of the fixture support block 12, and the hook clamp module 76 is used to press and disengage the outer button-type buckle mechanism 14, and then the outer servo module 72 is moved to achieve left and right position adjustment of the support block 12.

[0024] In addition, each servo module and cylinder actuator is equipped with an induction switch at the end of the motion position to determine the execution position signal. Each actuator automatically determines and adjusts according to the required position parameters set by the PLC and touch screen.

[0025] In this embodiment, the current collector plate 2 is provided with two sets of fixtures 1 , and the corresponding inner adjustment mechanisms 6 and outer adjustment mechanisms 7 are also provided in two sets.

[0026] Working principle of the present invention:

[0027] 1. The automatic adjustment mechanism sets the position parameters of the positioning block and the support block 12 that need to be adjusted through the touch screen of the main electronic control system, and starts the system operation.

[0028] 2. The collector plate 2 and the fixture 1 are transported by the conveyor line 3 (double-speed chain line), flow to the position of the adjustment mechanism, and are positioned by the positioning blockers 4 set in the front and back. The side positioning cylinder 5 pushes the collector plate 2 to the other side of the conveyor line 3 for precise positioning.

[0029] 3. After the system determines that the collector plate 2 is in place, the two sets of inner adjustment mechanisms 6 extend the inner photoelectric sensor switch and the clamp cylinder through the inner telescopic cylinder 64 (the purpose is to avoid interference between the collector plate 2 fixture rod and the inner photoelectric sensor switch). The inner servo module 62 moves the corresponding inner photoelectric sensor switch toward the center. When the infrared light from the two sets of inner photoelectric sensor switches contacts the corresponding positioning blocks, the two inner servo modules 62 stop moving respectively. At the same time, the stop position data is compared with the required position of the clamp set in the touch screen to determine the left and right movement direction. The two clamp cylinders clamp the inner button-type snap mechanism 13 at the rear end of the limit block 11, causing the limit block 11 to disengage from the serrated guide bar and move in the required left and right directions at the same time. After the limit block 11 moves to the required position, the clamp cylinder is loosened and the inner button-type snap mechanism 13 resumes its position. Then, after the inner telescopic cylinder 64 is returned to its position, the inner servo module 62 moves away from the center and toward both sides to its initial position, and the adjustment of the limit block 11 is completed.

[0030] 4. At the same time as the collector plate 2 is in place, the two sets of outer adjustment mechanisms 7 move the two sets of outer photoelectric sensors and the hook clamp module 76 toward the center at the same time through the outer servo module 72. When the infrared light from the two sets of outer photoelectric sensors contacts the corresponding support block 12, the two outer servo modules 72 stop moving, and at the same time compare the stop position data with the required position of the clamp set in the touch screen to determine the left and right movement direction of the support block 12. At the same time, the outer telescopic cylinder 75 extends the hook clamp module 76. After the U-shaped card slot at the head of the outer telescopic cylinder 75 is extended into place, it clamps the base of the support block 12. Then the reverse hook claw pressing piece 761 retracts, driving the reverse hook claw pressing piece 761 to stand up and press the outer button-type snap mechanism 14, so that the support block 12 is disengaged from the serrated guide bar and moves in the required left and right directions at the same time. After the support block 12 moves to the desired position, the claw telescopic cylinder 762 extends to release the reverse claw pressure plate 761, and the outer button-type snap mechanism 14 returns to its original position. Then, the outer telescopic cylinder 75 returns the claw clamp module 76 to its original position, and the outer servo module 72 moves away from the center to the sides to the initial position, completing the adjustment of the support block 12.

[0031] 5. After the limit block 11 and the support block 12 are adjusted, the front and rear positioning blockers 4 are lowered in sequence, the collector plate 2 is discharged, and the next collector plate 2 flows in, and the next cycle begins.

[0032] 6. Since the positions of the limit block 11 and the support block 12 required by each display product, as well as whether the four positions are enabled, can all be used as independent recipes for each model and stored in the touch screen in advance for easy call during subsequent product production.

[0033] The above describes a specific embodiment of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principles and essence of the present invention, but these changes and modifications will fall within the scope of protection of the present invention.
