Description

Technical Field

[0001] The invention relates to the technical field of plate processing auxiliary equipment, in particular to a pneumatically angle-adjustable positioning table. Background Art

[0002] During the sheet processing process, in order to control the sheet transportation, the position of the sheet needs to be transferred and controlled by a robot. Since the position of the sheet cannot be accurately fixed when it is placed, the position of the robot is different each time it grabs it. Therefore, it is necessary to place it on an operating table used for gravity positioning for secondary positioning, so as to assist the robot in accurately grabbing the sheet. However, the current operating table has a simple structure, resulting in a very low grabbing efficiency of the robot. During the grabbing and positioning processes, friction will be caused to the surface of the operating table, which will seriously affect the positioning efficiency and durability. In addition, the functionality of the traditional positioning table is also very simple. At the same time, it can only place square sheets, and there are few types of plates that can be positioned. If some special-shaped sheets are encountered, they cannot be accurately positioned. Summary of the Invention

The center position of the lower surface of the positioning table 2 is bolted with a bottom assembly frame 7 for movably assembling the bottom support frame 1. The two ends of the first telescopic motor 3 are movably assembled with the outer side surface of the bottom support frame 1 and the lower surface of the positioning table respectively. The lower surface of the positioning table 2 is located on the outside of the front end side wall and is welded with a first mounting base 8 for installing the second telescopic motor 4. The lower surface of the positioning table 2 is located on the outside of the right side wall and is welded with a second mounting base 9 for installing the third telescopic motor 5 and a third lateral mounting frame 10 for installing the high-precision displacement sensor 6. The upper surface of the positioning table 2 is slidably assembled with a first electrically-controlled telescopic extrusion component 11 controlled by the second telescopic motor 4 and a second electrically-controlled telescopic extrusion component 12 controlled by the third telescopic motor 5.

[0026] The first telescopic motor 3 , the second telescopic motor 4 , the third telescopic motor 5 and the high-precision displacement sensor 6 are existing technologies.

[0027] The first electrically controlled telescopic extrusion assembly 11 includes a first transverse extrusion frame 13 fixed to the top of the telescopic rod of the second telescopic motor 4 through a first bolt assembly seat, a first sliding adjustment groove 14 opened on the side wall of the first transverse extrusion frame 13, a first transverse adjustment screw rod 15 movably assembled in the first sliding adjustment groove 14, a first internal thread adjustment slider 16 threadedly sleeved on the outside of the first transverse adjustment screw rod 15, a first flip extrusion frame 17 movably mounted on the upper end of the first internal thread adjustment slider 16, and a fourth telescopic motor 18 movably mounted on the upper end of the first internal thread adjustment slider 16, and a first adjustment motor 19 fixed on the side wall of the first transverse extrusion frame 13 for controlling the rotation of the first transverse adjustment screw rod 15.

[0028] The fourth telescopic motor 18 and the first adjustment motor 19 are existing technologies. The first adjustment motor 19 drives the first internal thread adjustment slider 16 to translate in the first sliding adjustment groove 14 by driving the first lateral adjustment screw 15 to rotate, and then the first internal thread adjustment slider 16 drives the first flip extrusion frame 17 and the fourth telescopic motor 18 to translate and adjust.

[0029] In order to cooperate with longitudinal adjustment and flipping extrusion, the second electrically controlled telescopic extrusion assembly 12 includes a second transverse extrusion frame 20 fixed to the top of the telescopic rod of the third telescopic motor 5 by a second bolt assembly seat, a second sliding adjustment groove 21 opened on the side wall of the second transverse extrusion frame 20, a second transverse adjustment screw 22 movably assembled in the second sliding adjustment groove 21, a second internal thread adjustment slider 23 threadedly sleeved on the outside of the second transverse adjustment screw 22, a second flipping extrusion frame 24 movably mounted on the upper end of the second internal thread adjustment slider 23, and a fifth telescopic motor 25 movably mounted on the upper end of the second internal thread adjustment slider 23, and a second adjustment motor 26 fixed on the side wall of the second transverse extrusion frame 20 for controlling the rotation of the second transverse adjustment screw 22.

[0030] The fifth telescopic motor 25 and the second adjustment motor 26 are existing technologies. The second adjustment motor 26 drives the second internal thread adjustment slider 23 to translate in the second sliding adjustment groove 21 by driving the second lateral adjustment screw 22 to rotate, and then the second internal thread adjustment slider 23 drives the second flip extrusion frame 24 and the fifth telescopic motor 25 to translate and adjust.

[0031] In order to reduce the bottom friction by blowing air, 78 circular air holes 27 are opened on the positioning table 2, and a centrifugal air pump 28 is fixedly assembled on the outer surface of the bottom support frame 1 by bolts. The outer air outlet of the centrifugal air pump 28 is connected to the inside of the circular air hole 27 through a flexible air outlet pipe 29.

[0032] The centrifugal vacuum pump 28 discharges the air drawn in from the bottom through the flexible exhaust pipe 29 to the circular air vent 27, and then forms an air flow on the surface of the positioning table 2, thereby reducing the friction of the plate on the positioning table 2. The principle is similar to that of a hovercraft, and then the rapid sliding of the plate can be promoted.

[0033] In order to cooperate with the air intake and collect the dust generated on the outside at the same time, a bottom dust box 30 is bolted to the outer surface of the bottom support frame 1, and the air inlet at the lower end of the centrifugal vacuum pump 28 is fixedly connected to the interior of the bottom dust box 30. The upper end of the outer surface of the bottom dust box 30 is fixedly connected to the interior of the first flip extrusion frame 17 and the second flip extrusion frame 24 through a flexible air inlet pipe 31. The outer surfaces of the first flip extrusion frame 17 and the second flip extrusion frame 24 are provided with side dust extraction ports 32 that cooperate with the flexible air inlet pipe 31.

[0034] The centrifugal vacuum pump 28 is fixed to the upper end of the bottom dust box 30, and then the air from the bottom dust box 30 is drawn in, and then the bottom dust box 30 draws in the air from the side dust extraction port 32 through the flexible air inlet pipe 31, and then the air is filtered through the metal filter inside the air inlet at the lower end of the centrifugal vacuum pump 28, and the filtered air is drawn into the interior of the centrifugal vacuum pump 28.

[0035] In order to improve the bottom supporting force and applicability, the bottom support frame 1 includes an X-shaped structure bottom support frame 33 installed on the ground and a liftable longitudinal column 34 fixed to the upper end of the bottom support frame 33. The liftable longitudinal column 34 is movably connected to the bottom assembly frame 7 through an annular assembly frame 35 with an integrated top structure and is mounted on a transverse assembly axis located in the bottom assembly frame 7.

[0036] The liftable longitudinal column 34 can be lifted by electric control or manually controlled, which is a prior art.

[0037] In order to cooperate with the telescopic control flipping, thereby squeezing and positioning both sides of the plate, and then cooperate with the controlled transportation, the upper surfaces of the first flip extrusion frame 17 and the second flip extrusion frame 24 are fixedly equipped with an upwardly protruding top control rod, and the fourth telescopic motor 18 is movably assembled with the first flip extrusion frame 17 through the first control sleeve on the top of the telescopic rod, and the fifth telescopic motor 25 is movably assembled with the second flip extrusion frame 24 through the second control sleeve on the top of the telescopic rod.

[0038] The fifth telescopic motor 25 drives the first flipping and squeezing frame 17 upward and the second flipping and squeezing frame 24 downward by extending, thereby controlling the plate to be squeezed and positioned to the lower right.

[0039] In order to facilitate lifting detection, a lateral detection notch 36 for cooperating with lifting is opened on the positioning table 2 corresponding to the position of the high-precision displacement sensor 6.

[0040] The high-precision displacement sensor 6 is a prior art, which detects the thickness of the plate by squeezing the surface of the plate with the detection heads at the upper and lower ends.

[0041] In order to avoid obstruction of the high-precision displacement sensor 6 when taking the plate, the upper end of the third lateral mounting frame 10 is an outward-bent arc-shaped guide frame 37, and the outer side of the third lateral mounting frame 10 is fixedly equipped with a lateral adjustment motor 38 for controlling the high-precision displacement sensor 6 through a lateral bracket.

[0042] The rotating shaft of the lateral adjustment motor 38 is fixed to the high-precision displacement sensor 6 through a flip arm, and then the high-precision displacement sensor 6 is controlled by the lateral adjustment motor 38 to flip along the arc-shaped guide frame 37, so that the upper end opening of the positioning table 2 can be kept without affecting the removal of the plate.

[0043] The lateral adjustment motor 38 is prior art.

[0044] In order to improve the sealing performance of the opening position, the outer side surface of the first internal thread adjustment slider 16 located at the opening position of the first sliding adjustment groove 14 and the outer side surface of the second internal thread adjustment slider 23 located at the opening position of the second sliding adjustment groove 21 are both movably equipped with accordion covers 39 that are useful in improving the sealing performance.

[0045] The pneumatically adjustable angle positioning platform of the present invention is externally welded with a first mounting base 8 for mounting a second telescopic motor 4, a second mounting base 9 for mounting a third telescopic motor 5, and a third lateral mounting frame 10 for mounting a high-precision displacement sensor 6. This allows the positioning platform to not only adjust the positioning position of a plate as needed but also detect the thickness of the plate, greatly enhancing its applicability and functionality. A first electrically controlled telescopic extrusion assembly 11 controlled by the second telescopic motor 4 and a second electrically controlled telescopic extrusion assembly 12 controlled by the third telescopic motor 5 are slidably mounted on the upper surface of the positioning platform 2. This allows not only positioning of plates with different external structures but also improved efficiency in longitudinal and lateral translation of the plates on the positioning platform 2. A centrifugal vacuum pump 28 fixed to the outer surface of the bottom support frame 1 blows air through the circular air holes 27 on the positioning platform, thereby reducing friction and resistance during the plate positioning process. Dust removal is also possible from the outside, significantly improving environmental performance. A reversible extrusion frame controlled by a telescopic motor is movably mounted on the electrically controlled telescopic extrusion assembly, allowing for reversible control during idle time, greatly improving space utilization.

[0046] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
