[0062] The limiting member 130 is arranged on the mounting plate 110; specifically, the limiting member 130 is roughly U-shaped, that is, the limiting member 130 can be a beam portion and a column portion arranged at the two ends of the beam portion, and the two free ends of the U-shaped structure (that is, the free ends of the two column portions) can be fixed on the lower surface of the mounting plate 110.

[0063] At this time, there can be a preset interval between the cross beam portion of the stopper 130 and the mounting plate 110. In one embodiment, the stopper 130 includes a first surface and a second surface, wherein the first surface can be the upper surface of the cross beam portion, the upper surface of the cross beam portion can be parallel or substantially parallel to the lower surface of the stopper 130, and there is a preset interval between the upper surface of the cross beam portion and the lower surface of the stopper 130.

[0064] The second surface may be the inner surface of the above-mentioned beam portion. In a preferred embodiment, a preset angle is formed between the first surface and the second surface.

[0065] The rotating shaft 140 is rotatably supported by the mounting plate 110, and the rotating shaft 140 can be located below the mounting plate 110. In a specific embodiment, the length direction of the rotating shaft 140 can be set to be parallel to the above-mentioned beam portion.

[0066] Specifically, two bearing seats may be provided on the lower surface of the mounting plate 110 , and bearings may be provided in the bearing seats. At this time, both ends of the rotating shaft 140 can be rotatably supported by the bearings, so that the rotating shaft 140 can be driven and rotated by the driving device 120 .

[0067] More specifically, a gear is disposed on the rotating shaft 140 , and the rotating shaft 140 is driven to rotate through the cooperation between the gear and the rack.

[0068] The limiting member 130 is provided with a first limiting portion 160 and a second limiting portion 170 ; the first limiting portion 160 is provided on the first surface, and the second limiting portion 170 is provided on the second surface.

[0069] The seat component 150 is disposed on the rotating shaft 140 and is driven by the rotating shaft 140 to rotate between a first position and a second position, wherein when the seat component 150 is located at the first position, part of the seat component 150 contacts the first limiting portion 160, and when the seat component 150 is located at the second position, part of the seat component 150 contacts the second limiting portion 170.

[0070] Therefore, in the flip positioning device of the present invention, the seat component 150 can be accurately positioned at a preset position through the provision of the first limiting portion 160 and the second limiting portion 170, thereby solving the problems in the prior art.

[0071] More preferably, when the seat component 150 is located at the first position, the seat component 150 is located in the accommodating space, and a surface of the seat component 150 (for example, the upper surface of the seat component 150 ) is substantially on the same plane as the upper surface of the mounting plate 110 .

[0072] In a specific embodiment, the first limiting portion 160 includes a first stopping bolt, which is disposed on the first surface. When a surface of the seat component 150 contacts the first stopping bolt, the seat component 150 is limited to the first position by the first stopping bolt.

[0073] In addition, a first oil pressure buffer 161 is also provided on the first surface. When the seat member 150 is moving toward the first position and the first oil pressure buffer 161 is in contact with the seat member 150, the first stop bolt is not in contact with the seat member 150, so that the movement of the seat member 150 can be buffered by the first oil pressure buffer 161. In a specific embodiment, two first stop bolts are provided, and two first oil pressure buffers 161 are also provided. The two first oil pressure buffers 161 are provided on the outside of the two first stop bolts.

[0074] More preferably, a first proximity sensor 162 is further disposed on the first surface, so that the position of the seat component 150 can be detected by the first proximity sensor 162, and it can be determined whether the seat component 150 is accurately restricted to the first position.

[0075] On the other hand, the second limiting portion 170 includes a second stopping bolt disposed on the second surface. When one surface of the seat component 150 contacts the second stopping bolt, the seat component 150 is limited to the second position by the second stopping bolt.

[0076] The second surface is also provided with a second oil pressure buffer 171. When the seat member 150 is moving toward the second position and the second oil pressure buffer 171 is in contact with the seat member 150, the second stop bolt is not in contact with the seat member 150, so that the movement of the seat member 150 can be buffered by the second oil pressure buffer 171. In a specific embodiment, two second stop bolts are provided, and two second oil pressure buffers 171 are also provided. The two second oil pressure buffers 171 are provided on the outside of the two second stop bolts.

[0077] More preferably, a second proximity sensor 172 is further disposed on the second surface, so that the position of the seat component 150 can be detected by the second proximity sensor 172, and it can be determined whether the seat component 150 is accurately restricted in the second position.

[0078] The flip positioning device also includes a jig assembly 180 and a pressure block assembly 190. The jig assembly 180 is disposed on the seat component 150. The pressure block assembly 190 is rotatably disposed on the jig assembly 180. The workpiece is positioned by the cooperation between the pressure block assembly 190 and the seat component 150.

[0079] Specifically, the jig assembly 180 can be configured to be roughly in the shape of a workpiece, and the jig assembly 180 includes a vacuum suction cup, which is used to adsorb the workpiece, so that the jig assembly 180 can hold the workpiece. More preferably, the rotating shaft 140 can be a hollow shaft, at least part of the outer peripheral surface of the rotating shaft 140 is a plane, and the seat component 150 is installed on the rotating shaft 140, so that the plane portion of the rotating shaft 140 is closely fitted with the lower surface of the seat component 150.

[0080] The rotating shaft 140 is provided with exhaust holes in the radial direction, so that negative pressure can be transmitted to the jig assembly 180 through the rotating shaft 140 , and thus the jig assembly 180 can achieve adsorption of the workpiece.

[0081] The seat component 150 is provided with a first adsorption portion 151, and the pressing block assembly 190 includes a second adsorption portion 191, and the workpiece is held between the fixture assembly 180 and the pressing block assembly 190 by the attraction between the first adsorption portion 151 and the second adsorption portion 191. In a preferred embodiment, one of the first adsorption portion 151 and the second adsorption portion 191 may be a magnet, and the other may be a magnet or iron sheet, so that the first adsorption portion 151 and the second adsorption portion 191 can attract each other.

[0082] Therefore, the flip positioning device disclosed in the present invention can position the workpiece through the arrangement of the fixture assembly and the pressure block assembly 190. When flipping the product, the position of the workpiece is limited through the combined action of adsorption and clamping, which can offset the centrifugal force and vibration generated by the workpiece during the flipping process, ensuring that the product is stable and does not shake during flipping, that is, effectively limiting the position of the product and preventing the product from moving, and greatly ensuring the processing accuracy. In particular, by replacing different fixture assemblies and pressure block assemblies, the positioning and flipping requirements of different products can be achieved, reducing the cost of modification and replacement.

[0083] In addition, the flipping and positioning device disclosed in the present invention is equipped with a gear rack and is powered by a cylinder to drive the rotating shaft to rotate, so that the entire fixture assembly can be rotated 90°, and the workpiece can remain stable during the flipping process, and the flipping and positioning device disclosed in the present invention can be applied to a variety of occasions requiring side processing.

[0084] Back-to-back bearings may be arranged in the bearing seat, thereby improving the rotational stability of the rotating shaft and also improving the flipping accuracy of the flipping positioning device disclosed in the present invention.

[0085] The air path of the present invention enters from the end faces on both sides of the rotating shaft, is connected to the fixture assembly after being connected to the seat component under the fixture assembly, and provides an air source for the vacuum suction cup, thereby ensuring the stability of the air path. When flipping, the air path also flips together, avoiding blockage or damage to the air pipe due to excessive flipping.
