[0002] The box-turning feeder consists of a ground rail, a robotic arm on the ground rail working platform, a vision guide rail, an industrial camera on the vision working platform, a code scanning mechanism, a cleaning mechanism and a cover-removing mechanism, etc. It completes the work processes of grabbing, scanning, removing covers, turning over boxes, cleaning, closing covers and placing boxes at different work stations. The zero position of the ground rail working platform and the zero position of the vision working platform determine the working starting position of the feeder.

DETAILED DESCRIPTION

[0017] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0018] Embodiments of the present invention: Figure 1-Figure 5 As shown, a zero point calibration tool for a box feeder includes a tool base 1 and a tool positioning rod 2. One side of the tool base 1 has a ground rail connection surface, and the other side of the tool base 1 has a ground rail working platform connection surface. The tool positioning rod 2 is plugged into and slidably connected to the tool base 1.

[0019] The fixture base 1 is connected to the floor rail 5 via the floor rail connection surface, and the fixture positioning rod 2 allows for rapid calibration of the zero point of the visual work platform 6. The fixture base 1 is also connected to the floor rail work platform 4 via the floor rail work platform connection surface, and the fixture positioning rod 2 allows for rapid calibration of the zero point of the floor rail work platform 4. This effectively addresses existing issues that can occur during feeder operation, such as offset box grabbing, incorrect code scanning position, the lid removal mechanism failing to center the box lid, the material dumping position shifting from the silo, and the box placement not being centered on the pallet.

[0020] Specifically, the tooling base 1 includes a plate body 11 and a tooling positioning rod mounting block 12. The tooling positioning rod mounting block 12 is fixed at one end of the plate body 11. A tooling positioning rod mounting hole 13 is opened on the tooling positioning rod mounting block 12 along its length direction. The tooling positioning rod 2 is plugged into and slidably connected to the tooling positioning rod mounting hole 13.

[0021] In this embodiment, the tool positioning rod mounting block 12 is arranged perpendicular to the plate body 11, and the two are integrally formed.

[0022] The diameter of the tool positioning rod mounting hole 13 is equal to the diameter of the tool positioning rod 2. In order to facilitate the connection between the tool positioning rod 2 and the tool positioning rod mounting hole 13, chamfers are preferably processed at both ends of the tool positioning rod mounting hole 13.

[0023] A conical end 21 is formed at one end of the tooling positioning rod 2, and a scale 22 is provided on the rod body of the tooling positioning rod 2. The end face of the conical end 21 is at the 0 scale position, and the scale value gradually increases from the end face of the conical end 21 to the other end of the tooling positioning rod 2.

[0024] Furthermore, a floor rail working platform connecting plate 14 is fixedly provided on one side of the plate body 11. The floor rail working platform connecting plate 14 is perpendicular to the plate body 11, and the floor rail working platform connecting plate 14 is parallel to the tool positioning rod mounting block 12. A locking hole 15 is opened on the floor rail working platform connecting plate 14, and the axis of the locking hole 15 is perpendicular to the axis of the tool positioning rod mounting hole 13.

[0025] One end of the tooling positioning rod mounting block 12 forms a U-shaped connecting surface with the plate body 11 and the ground rail working platform connecting plate 14. The U-shaped connecting surface is the ground rail working platform connecting surface.

[0026] The other end of the tooling positioning rod mounting block 12 forms an L-shaped connecting surface with the plate body 11 , and the L-shaped connecting surface is a ground rail connecting surface. A waist-shaped hole 16 is opened on the plate body 11 .

[0027] The working principle of the present invention is as follows: when calibrating the zero point of the floor rail working platform 4, the offset of the floor rail working platform 4 must first be measured. Then the floor rail working platform 4 is adjusted to the electrical zero position, and the floor rail working platform connection surface of the tooling base 1 is connected to the floor rail working platform 4. Then, a bolt (not shown) is used to thread the locking hole 15, and the end of the bolt is abutted against the floor rail working platform 4, thereby fixing the tooling base 1 on the floor rail working platform 4. At this time, the state is as follows: Figure 4 As shown, first align the conical end 21 of the fixture positioning rod 2 with the stop block 3, read the scale value on the fixture positioning rod 2, and then adjust the position of the floor rail working platform 4 based on the offset value, so that the adjusted displacement of the floor rail working platform 4 is equal to the offset value. The displacement value can be determined by observing the changes in the scale on the fixture positioning rod 2 as the floor rail working platform 4 is adjusted. The adjusted floor rail working platform 4 is at the zero point.

[0028] When calibrating the zero point of the visual work platform 6, first measure the offset of the visual work platform 6. Then adjust the visual work platform 6 to the electrical zero position, then connect the ground rail connection surface of the tooling base 1 to the ground rail 5, and use the locking screw 17 to pass through the waist hole 16 and then thread it into the threaded hole on the end face of the ground rail 5 and tighten it to prevent the tooling base 1 from moving on the ground rail 5. Figure 5 Then, place the conical end 21 of the tooling locating rod 2 in contact with the visual work platform 6. Read the scale value on the tooling locating rod 2 at this point. Then, adjust the position of the visual work platform 6 based on the offset, ensuring that the adjusted displacement of the visual work platform 6 equals the offset. The displacement can be determined by observing the changes in the scale on the tooling locating rod 2 as the visual work platform 6 is adjusted. The adjusted visual work platform 6 is at its zero point.

[0029] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
