Description

Technical Field

[0001] The present invention relates to the technical field of alignment jigs, and in particular to a pneumatic automatic alignment jig. Background Art

[0002] During the production process of in-vehicle displays, CG lamination is usually required. During the lamination process, a positioning jig is usually required to clamp and limit the display, making the display more stable and convenient for subsequent lamination.

[0003] Some of the existing alignment jigs are either simple limit frames, which allow the monitor to be placed directly after adjusting the surrounding alignment blocks, or they are clamped by squeezing with multiple sets of cylinders. However, when multiple sets of cylinders are used for alignment and extrusion, the different intake and exhaust volumes between different sets of cylinders will cause the multiple sets of cylinders to squeeze the monitor for different times and with different strengths. For example, for two sets of cylinders set at an angle, one set of cylinders may push the limit blocks to squeeze the wide side of the monitor, while the cylinder on the narrow side has not yet contacted the monitor. At this time, the two wide sides of the monitor whose wide side is squeezed are squeezed by the cylinder and the jig body respectively. At this time, the cylinder on the narrow side is in contact with and squeezes the monitor. At this time, both wide sides of the monitor are squeezed when it moves, which can easily cause the wide side to be damaged by friction during movement. Summary of the Invention

[0004] The purpose of the present invention is to provide a pneumatic automatic alignment fixture to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above-mentioned object, the present invention provides the following technical solution: a pneumatic automatic alignment jig, comprising a base, on which a jig body is rotatably mounted, a cylinder seat fixedly mounted on the jig body, a limit cylinder fixedly mounted on the cylinder seat, and a limit block mounted on the output end of the limit cylinder; a rotating shaft fixedly mounted on the jig body, a limit cylinder fixedly mounted on the base, the rotating shaft rotatably mounted in the limit cylinder; a round rod fixedly mounted on the rotating shaft, and a spiral groove formed on the round rod;

[0006] A side plate is fixedly mounted on the limit block, a sliding frame is slidably mounted on the base, a slide plate is fixedly mounted on the slide frame, and an inserting strip plugged into the spiral groove is fixedly mounted on the slide plate.

[0007] Preferably, an arc-shaped groove is provided on the sliding frame, and the bottom end of the side plate is arranged in an arc shape.

[0008] Preferably, a movable block is fixedly mounted on the output end of the limiting cylinder, the movable block is slidably mounted inside the limiting block, and a spring is fixedly mounted between the movable block and the limiting block.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1-6 , a pneumatic automatic alignment fixture comprises a base 1, a fixture body 2 is rotatably mounted on the base 1, a cylinder seat 4 is fixedly mounted on the fixture body 2, a limit cylinder 51 is fixedly mounted on the cylinder seat 4, and a limit block 3 is mounted on the output end of the limit cylinder 51;

[0027] A rotating shaft 61 is fixedly mounted on the fixture body 2, and a limiting cylinder 62 is fixedly mounted on the base 1. The rotating shaft 61 is rotatably mounted in the limiting cylinder 62.

[0028] A round rod 63 is fixedly mounted on the rotating shaft 61, and a spiral groove 631 is formed on the round rod 63;

[0029] The limit block 3 is fixedly mounted with a side plate 64, the base 1 is slidably mounted with a slide frame 65, the slide frame 65 is fixedly mounted with a slide plate 66, and the slide plate 66 is fixedly mounted with an insert 67 that is plugged into the spiral groove 631;

[0030] Among them, the display 8 is placed on the fixture body 2, and then the limit cylinder 51 is started. At this time, the limit cylinder 51 will push the limit block 3 close to the display 8 and cooperate with the alignment angle of the fixture body 2 to limit the display 8;

[0031] When the limiting cylinder 51 pushes the limiting block 3 to move inward, the side plate 64 on the limiting block 3 will first drive the slide frame 65 to move. At this time, the slide frame 65 will drive the insertion bar 67 to move through the slide plate 66 thereon. As the insertion bar 67 moves horizontally, it will drive the round rod 63 to rotate through the spiral groove 631. The rotation of the round rod 63 will drive the rotating shaft 61 to rotate in the limiting cylinder 62, thereby causing the fixture body 2 to rotate upward on the base 1. Figure 2In the state, when the jig body 2 rotates upward, the limit block 3 has not yet squeezed the display 8, and the display 8 will slide up and down the jig body 2 due to gravity. At this time, the bottom end of the display 8 will be closely fitted with the jig body 2 to be positioned. As the limit block 3 continues to move inward, it will push the display 8 so that it is squeezed and limited by the limit block 3 and the alignment angle. At this time, the entire display 8 can be positioned and limited by a single limit block 3;

[0032] When the slide plate 66 moves, the inserting strip 67 thereon translates in the spiral groove 631 and presses the inner wall of the spiral groove 631 , so that the round rod 63 drives the rotating shaft 61 to rotate through the spiral groove 631 .

[0033] In another embodiment of the present invention, an arc-shaped groove is provided on the sliding frame 65, and the bottom end of the side plate 64 is arranged in an arc shape;

[0034] The arc line of the arc groove and the arc line of the bottom end of the side plate 64 are set concentrically. When the side plate 64 rotates following the fixture body 2, the bottom end of the side plate 64 rotates along the inner wall of the slide frame 65, but does not separate from the slide frame 65. Therefore, when the side plate 64 moves inward or outward following the limit block 3, the side plate 64 can drive the slide frame 65 to move, so that the slide frame 65 drives the slide plate 66 to move.

[0035] In another embodiment of the present invention, a movable block 52 is fixedly mounted on the output end of the limit cylinder 51 , the movable block 52 is slidably mounted inside the limit block 3 , and a spring is fixedly mounted between the movable block 52 and the limit block 3 ;

[0036] When the limiting cylinder 51 pushes the movable block 52 to move inward, the movable block 52 will first squeeze the spring and then push the spring, thereby using the spring to push the limiting block 3 to move, so that the limiting block 3 has a certain buffering effect on the squeezing and limiting of the display 8.

[0037] In another embodiment of the present invention: an outer plate 53 is fixedly mounted on the limit block 3, and the outer plate 53 is used to limit the outward movement of the movable block 52;

[0038] When the limiting cylinder 51 moves to drive the movable block 52 to move outward, until the movable block 52 contacts the outer plate 53, the movable block 52 will drive the limiting block 3 to move outward by pulling the outer plate 53, thereby releasing the limiting block 3 from limiting the display 8.

[0039] In another embodiment of the present invention: the fixture body 2 is provided with an air hole 21;

[0040] When the display 8 is placed in the fixture body 2, the base 1 will drive the display 8 to move toward the bottom of the membrane plate 9 until it is directly below. At this time, the limit cylinder 51 moves inward. As the limit cylinder 51 moves, it will push the limit block 3 to move through the movable block 52 and the spring, so that the limit block 3 limits the display 8. At this time, the display 8 is in a tilted state. Figure 6 As shown, as the diaphragm 9 continues to move downward, the limiting cylinder 51 will also move inward at the same time, and the output end of the limiting cylinder 51 can continue to move through the movable block 52 and the spring. As the limiting cylinder 51 moves, it will drive the slide 66 and the insert 67 thereon to move in the spiral groove 631. At this time, the round rod 63 will drive the fixture body 2 to rotate downward, and at the same time the air hole 21 can be connected to the hose for suction. The air hole 21 is located on the left side of the fixture body 2. As the diaphragm 9 is pressed downward, a high pressure is generated between it and the display 8. The degree of lamination is poor, and the spacing on the left is large and the spacing on the right is small. When the air hole 21 inhales air, the air flow passes between the diaphragm 9 and the display 8. Due to the small spacing on the right, the air on the left is more easily sucked away, and at the same time, the air intake on the right is less. Since the fixture body 2 and the limit block 3 are limited on the two long sides of the display 8, the display 8 and the diaphragm 9 are blocked on both sides. At this time, as the air hole 21 inhales air, the air between the diaphragm 9 and the display 8 will be sucked away faster, so that there is less air between the two when fitting, and it is not easy to generate bubbles.

[0041] In another embodiment of the present invention, a long plate 71 is slidably mounted on the jig body 2, an extrusion block 72 is vertically slidably mounted on the jig body 2, a first oblique block 74 is fixedly mounted on the bottom end of the extrusion block 72, and a second oblique block 73 is fixedly mounted on the long plate 71;

[0042] The long plate 71 is L-shaped;

[0043] When the limit block 3 moves outward, the limit block 3 will drive the long plate 71 to move. As the long plate 71 moves, the second inclined block 73 on it will squeeze the first inclined block 74. At this time, the second inclined block 73 will drive the extrusion block 72 to rise through the first inclined block 74. As the extrusion block 72 rises, it will extend from the surface of the jig body 2. At this time, the extrusion block 72 will push the display 8 to separate on the jig surface, making it convenient for the staff to reach in between the display 8 and the jig body 2 with their hands, making it convenient to take the display 8.

[0044] In another embodiment of the present invention: a return spring is fixedly installed between the long plate 71 and the fixture body 2;

[0045] When the limit block 3 moves toward the jig body 2, the return spring will pull the long plate 71 inward. At this time, the squeezing block 72 will also be able to drop into the jig body 2 so that the bottom end of the display 8 and the jig body 2 fit together. Therefore, when the limit block 3 has not yet squeezed the display 8, the squeezing block 72 has already slid into the jig body 2.

[0046] In another embodiment of the present invention: a rubber pad is provided on the extrusion block 72;

[0047] The rubber pad is used to prevent the display 8 from being damaged.

[0048] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
