[0002] In the process of processing the workpiece, it is often necessary to flip the workpiece to facilitate the production or processing of the next step. At present, most of the workpieces are flipped by clamping, that is, after the workpiece is clamped, the fixture is flipped by the driving component to realize the flipping action of the workpiece, and then the workpiece located on the flipping device is transported by the transport device.

[0003] In the current technical solution, the workpiece can be flipped, but only a single or a fixed number of workpieces can be flipped intermittently, and then the flipped workpiece needs to be removed before the other workpieces can be flipped again.

The second driving shaft and the second driven shaft are rotatably connected to the frame. The second conveyor belt is twisted 180 degrees in the same twisting direction as the first conveyor belt, and both ends are respectively sleeved on the second driving shaft and the second driven shaft, so that the first conveyor belt gradually tilts from both ends to the middle position and defines a second flipping portion in the middle that is vertically arranged and corresponds to the first flipping portion.

[0008] Further, the first driving shaft is located on the upper side of the second driving shaft, and the first driven shaft is located on the lower side of the second driven shaft.

[0009] Furthermore, the first conveyor belt and the second conveyor belt both include a belt body layer, the elastic deformation layer is attached to the belt body layer, and the elastic deformation layer is made of one of foam material, fiber cotton material, and cotton and linen material.

[0010] Furthermore, an adjustment unit is provided on the frame to adjust the spacing between the flipping channels. The adjustment unit is arranged between the first belt unit and the second belt unit, and includes four clamping rollers. Every two of the clamping rollers are opposed to each other up and down and are respectively located at both ends of the flipping assembly, and are respectively inserted into the first conveyor belt and the second conveyor belt.

[0011] Furthermore, a sliding groove along the vertical direction is opened on the frame at a position corresponding to the clamping roller, and both ends of the clamping roller are slidably connected in the sliding groove along the vertical direction, but fasteners for locking in the sliding groove are also respectively provided at both ends of the clamping roller.

A through hole is arranged on the side wall of the seat body away from the flip assembly; The pulling member has one end passing through the through hole and forming a threaded connection with the end of the shaft body, and the other end forming a rotating end for rotating the pulling member.

[0014] The beneficial effects produced by the present invention are as follows: During the process of flipping the workpiece, the workpiece is placed in the flipping channel, wherein the flipping channel is defined by two first belt units and a second belt unit stacked on top of each other in the vertical direction. Therefore, after the workpiece is placed in the flipping channel, the workpiece is placed on one of the belt units and clamped by the other belt unit located on the upper side, so that the workpiece is transported during the transmission of the belt unit. At this time, since the flipping channel is twisted 180 degrees along the axial direction, during the transportation of the workpiece, it gradually flips following the twisting of the flipping channel, thereby realizing the flipping of the workpiece 180 degrees.

DETAILED DESCRIPTION

[0022] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0023] An embodiment of the present invention provides a flexible double-belt flipping device for flipping workpieces during transportation, thereby achieving continuous flipping and transportation, thereby reducing the efficiency of workpiece feeding or transportation due to the need to flip the workpieces.

[0024] Specifically, if Figure 1-6 As shown, an embodiment of the present invention provides a flexible double-belt flipping device, comprising two opposed frames 100, on which a flipping assembly 200 for conveying and flipping a workpiece is rotatably arranged, the flipping assembly 200 is provided with a flipping channel 201 for conveying the workpiece along the axial direction, and the flipping channel 201 is twisted one hundred and eighty degrees along the axial direction; the flipping assembly 200 comprises a first belt unit 210 and a second belt unit 220 which are arranged side by side and stacked in the up-down direction, the flipping channel 201 is defined between the first belt unit 210 and the second belt unit 220, and the workpiece is clamped in the flipping channel 201; and an elastic deformation layer 202 is provided on the surface of the first belt unit 210 and the second belt unit 220 facing the flipping channel 201, in the process of clamping the workpiece for conveying along the flipping channel 201, the elastic deformation layer 202 undergoes contour-matching elastic deformation along the surface contour of the workpiece when clamping the workpiece.

[0025] During the process of turning over the workpiece, the workpiece is placed in the turning channel 201, wherein the turning channel 201 is defined by two first belt units 210 and second belt units 220 stacked on top of each other in the vertical direction. Therefore, after the workpiece is placed in the turning channel 201, the workpiece is placed on one of the belt units and clamped by the other belt unit located on the upper side, so that the workpiece is transported during the belt unit transmission. At this time, since the turning channel 201 is twisted 180 degrees along the axial direction, during the conveying process of the workpiece, it gradually turns over following the twisting of the turning channel 201, thereby realizing the turning of the workpiece 180 degrees. An elastic deformation layer 202 is arranged on both belt units. Therefore, after the workpiece is placed in the turning channel 201, the two belt units clamp the workpiece, so that the elastic deformation layer 202 elastically deforms following the surface contour of the workpiece, and the elastic deformation shape is similar to the surface contour of the workpiece, thereby ensuring that the workpiece will not fall in the turning channel 201 during the process of turning and turning following the turning channel 201, thereby ensuring the stability of the turning and conveying of the workpiece.

[0026] In this embodiment, if Figure 4-5 As shown, the first belt unit 210 includes a first driving shaft 211, a first driven shaft 212 and a first conveyor belt 213. The first driving shaft 211 and the first driven shaft 212 are rotatably connected to the frame 100. After the first conveyor belt 213 is twisted 180 degrees along the axis, both ends are respectively sleeved on the first driving shaft 211 and the first driven shaft 212, so that the first conveyor belt 213 gradually tilts from both ends to the middle position and defines a first turning portion 214 arranged in a vertical direction in the middle; the second belt unit 220 includes The second driving shaft 221, the second driven shaft 222 and the second conveyor belt 223 are rotatably connected to the frame 100. The second conveyor belt 223 is twisted 180 degrees in the same twisting direction as the first conveyor belt 213, and the two ends are respectively sleeved on the second driving shaft 221 and the second driven shaft 222, so that the first conveyor belt 213 gradually tilts from the two ends to the middle position and defines a second turning portion 224 in the middle that is arranged in a vertical direction and corresponds to the first turning portion 214.

[0027] In this embodiment, the first conveyor belt 213 and the second conveyor belt 223 are arranged side by side and close to each other, thereby defining a flip channel 201 for conveying and flipping the workpiece. During the transmission of the two conveyor belts, the conveying action of the workpiece is realized. At the same time, the two conveyor belts are twisted in the same direction, thereby realizing the twisting of the conveying channel, and the positions corresponding to the first flipping part 214 and the second flipping part 224 are in a vertical state. This position also constitutes the critical point for the workpiece to flip during the conveyance process along the flip channel 201. After passing through the flipping part, the workpiece gradually flips to present another surface facing the upper side (that is, the surface previously facing the lower side is flipped to face the upper side).

[0028] More specifically, the first driving shaft 211 is located on the upper side of the second driving shaft 221, and the first driven shaft is located on the lower side of the second driven shaft 222. Thus, normal transmission after the first conveyor belt 213 and the second conveyor belt 223 are turned over can be achieved.

[0029] In this embodiment, the first conveyor belt 213 and the second conveyor belt 223 have the same structure, that is, the first conveyor belt 213 and the second conveyor belt 223 both include a belt body layer 215 and an elastic deformation layer 202, wherein the elastic deformation layer 202 is attached to the belt body layer 215, and the elastic deformation layer 202 is made of one of foam material, fiber cotton material, and cotton and linen material. In the process of conveying the workpiece, when the workpiece is placed in the flip channel 201, the first conveyor belt 213 and the second conveyor belt 223 clamp and press the workpiece, so that the elastic deformation layer 202 elastically deforms according to the contour of the workpiece surface, and the shape after deformation is similar to the contour of the workpiece, that is, the workpiece is embedded in the elastic deformation layer 202, so that in the process of conveying and flipping the workpiece, the workpiece can remain stable under the restriction of the elastic deformation layer 202, and avoid falling in the flip channel 201. In this embodiment, the belt body layer can be formed by the conveyor belt in the prior art, and the elastic deformation layer composed of foam is pasted on the belt body layer.

[0030] In this embodiment, in order to adjust the gap between the flip channels 201 so as to adapt to workpieces of different thicknesses and maintain sufficient clamping force, an adjustment unit 300 is further provided on the frame 100 to adjust the spacing between the flip channels 201. The adjustment unit 300 is provided between the first belt unit 210 and the second belt unit 220, and includes four clamping rollers 301. Every two clamping rollers 301 are opposed to each other up and down and are respectively located at both ends of the flip assembly 200, and are respectively passed through the first conveyor belt 213 and the second conveyor belt 223.

[0031] That is to say, a clamping roller 301 is provided at the active end and the driven end of the first conveyor belt 213. Similarly, a clamping roller 301 is provided at the active end and the driven end of the second conveyor belt 223. The two clamping rollers 301 that are not located at the same end are arranged corresponding to each other in the up and down directions, so that the corresponding parts of the first conveyor belt 213 and the second conveyor belt 223 can interfere with each other, so that separation or approach can be achieved under the interference of the upper and lower opposing clamping rollers 301, thereby adjusting the gap of the flip channel 201.

[0032] In order to better adjust, a slide groove along the vertical direction is also provided on the frame 100 at a position corresponding to the clamping roller 301, and both ends of the clamping roller 301 are slidably connected in the slide groove 101 along the vertical direction, but both ends of the clamping roller 301 are respectively provided with fasteners for locking in the slide groove 101. In this embodiment, the clamping roller 301 slides along the slide groove 101, so that the gap between the two clamping rollers 301 can be changed, and then the gap of the flip channel 201 can be adjusted. The fastener can be a bolt threadedly connected to the end of the clamping roller 301, so that after the bolt is screwed in, it is fastened to the frame 100 through a nut, so that the clamping roller 301 can be fixed in the slide groove 101.

[0033] In this embodiment, in order to drive the two conveyor belts, a driving motor 110 is further provided on the frame 100, and synchronous wheels 111 are fixedly mounted on the ends of the first driving shaft 211 and the second driving shaft 221. The driving motor 110 drives the first driving shaft 211 and the second driving shaft 221 to rotate in opposite directions through the synchronous wheels 111. The two conveyor belts are driven by the same driving motor 110, so that the surface transmission directions and speeds of the two conveyor belts defining the turning channel 201 are the same, thereby ensuring the stability of the transmission and turning of the workpiece in the turning channel 201.

[0034] To adjust the tension of the two conveyor belts and to adjust in the event of deviation, such as Figure 2-3As shown, the first driven shaft 212 and the second driven shaft 222 both include a shaft body 2121 and a sleeve 2122 rotatably connected to the shaft body 2121; at the same time, two tensioning structures corresponding to the first driven shaft 212 and the second driven shaft 222 are also provided on the frame 100, and the tensioning structure includes a fixed seat and a pulling member, wherein a tensioning groove 122 facing the other end of the frame 100 is provided on the seat body 121, and both ends of the shaft body 2121 are slidably connected in the tensioning groove 122, and a through hole 123 is provided on the side wall of the seat body 121 away from the flip assembly 200; one end passes through the through hole 123 and is threadedly connected to the end of the shaft body 2121, and the other end constitutes a rotating end for rotating the pulling member. In this embodiment, the pulling member is also a bolt. By rotating the rotating end of the bolt, the shaft body 2121 can be pulled to move along its length direction within the tensioning groove 122, thereby adjusting the position of the shaft body 2121 and adjusting the conveyor belt that is deviating or loose, thereby ensuring the reliability of transportation.
