Description

Technical Field

[0001] The present invention relates to the technical field of sheet handling, and more particularly, to a handling module that can rotate arbitrarily. Background Art

[0002] Industrial blades are designed into special shapes according to actual cutting needs. Therefore, there are significant differences in shape between industrial blades and the blades used in daily life. Industrial blades are made by blanking and cutting a corresponding metal sheet into a rough shape, and then enter the edge-opening stage, where the edge part is ground and sharpened by a grinding wheel.

[0003] Among them, the blanked blades are in pieces, so a handling device is used to grab the blades one by one to the grinding position. To improve the grinding efficiency, the grinding and edge-opening equipment usually has multiple grinding positions to achieve batch edge-opening. The grinding positions are distributed at various positions of the grinding wheel. Correspondingly, in order for the blade handling device to make the blade reach the predetermined grinding position, the handling device needs to have the ability to move and feed at multiple angles. The existing blade handling devices are complex in mechanical design and have a single function, with a slow speed of feeding the blade blanks, and the rotation speed after the blade blanks are ground is restricted by the blade handling device, resulting in an inability to increase the production speed.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0031] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the connection inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0032] The present invention specifically discloses a handling module that can rotate arbitrarily, such as Figures 1-11As shown in the figure, it includes: a base 11 with a through opening in the center. There is a through opening in the middle area of the base 11. At the top of the base 11, an annular mounting part 12 is fixedly installed around this through opening. On the surface of the mounting part 12, blade fixing units 13 for clamping a blank 700 are movably installed at uniform intervals. A bracket 14 is fixedly installed on the base 11. The top of the bracket 14 is erected above the mounting part 12. There is a round hole at the top of the bracket 14. A gear ring 15 is rotatably installed at the round hole at the top of the bracket 14. The center of the gear ring 15 matches the center of the round hole. A first motor 16 is installed at the top edge of the bracket 14. A driving gear 17 is driven and installed on the first motor 16. The driving gear 17 meshes with the gear ring 15. The gear ring 15 can be rotated by the first motor 16 to drive the driving gear 17 to rotate. A first mounting plate 18 is centrally installed on the gear ring 15. On one side of the first mounting plate 18, a feeding mechanism 19 is provided. The feeding mechanism 19 extends downward through the round hole opened at the top of the bracket 14. The blank 700 to be polished can be pre-stored in the feeding mechanism 19. After the feeding mechanism 19 extends downward and is aligned with a single blade fixing unit 13, the blank 700 can be inserted into the blade fixing unit 13. As the gear ring 15 rotates, the feeding mechanism 19 can sequentially install the blank 700 on each blade fixing unit 13 on the mounting part 12. On the other side of the first mounting plate 18, a blank extracting mechanism 110 is installed. That is, the blank extracting mechanism 110 and the feeding mechanism 19 are two mechanisms with opposite arrangement directions. The blank extracting mechanism 110 can move in the up-down, left-right directions. After the blank 700 is polished and sharpened, the blank extracting mechanism 110 extracts the blank 700 from the blade fixing unit 13. Through the mutual cooperation of the feeding mechanism 19 and the blank extracting mechanism 110, while extracting the blank, the blank 700 to be polished can be inserted into the blade fixing unit 13 at the same time. An angle deflection mechanism 111 is installed on the mounting part 12 and is connected to the blade fixing unit 13. The angle deflection mechanism 111 acts on the blade fixing unit 13, enabling the blade fixing unit 13 to deflect a certain angle, so that the blank 700 will also deflect accordingly to achieve a suitable polishing angle.

[0033] Specifically, before use, a polishing device needs to be installed at the through opening part opened on the base 11. Refer to Figure 2As shown in the figure, the grinding device mainly includes the second motor 801 in the driving part, the second fixing plate 802 and the arc-shaped grinding part 803 in the grinding part. The second motor 801 drives the second fixing plate 802 to rotate. Arc-shaped grinding parts 803 are arranged at the two ends of the second fixing plate 802. After the knife blank 700 is installed on the blade fixing unit 13 through the feeding mechanism 19, the angle deflection mechanism 111 is used to make the arc-shaped cutting edge 701 of the knife blank 700 to be ground abut against the arc-shaped grinding part 803. Therefore, after the second fixing plate 802 rotates, the arc-shaped grinding part 803 can grind the arc-shaped cutting edge 701 on the knife blank 700. After one side of the cutting edge is ground, the blade fixing unit 13 drives the knife blank 700 to rotate to the other side. Since the arc-shaped cutting edge 701 changes to the other side, the rotation direction of the second fixing plate 802 also needs to rotate along the inclination direction of the knife blank 700, so as not to damage the knife blank 700 easily when grinding the arc-shaped cutting edge 701 on the other side. When the cutting edges on both sides are ground, the knife blank 700 is rotated back to a flat state, and the knife blank 700 can be drawn out through the material extraction mechanism 110 and dropped through the through hole opened on the base 11.

[0034] In the present invention, the gear ring 15 drives the feeding mechanism 19 and the material extraction mechanism 110 to rotate intermittently in the installation part 12. During the rotation process, the knife blank 700 is installed on the blade fixing unit 13 through the feeding mechanism 19. After the installation of the knife blank 700 is completed, the angle deflection mechanism 111 is used to deflect the knife blank 700 by a certain angle to complete the grinding. Subsequently, the ground knife blank 700 is drawn out by the material extraction mechanism 110 on the other side. The two mechanisms cooperate with each other to quickly complete the operation of replacing the knife blank 700, thereby effectively improving the grinding efficiency.

[0035] Refer to Figure 2 and Figure 4 As shown in the figure, the blade fixing unit 13 includes: fixing blocks 21 rotatably installed on the installation part 12 at uniform intervals. A receiving groove 23 allowing the knife blank 700 to be placed is opened on the fixing block 21. The locking teeth 22 are slidably installed on the fixing block 21 and penetrate into the receiving groove 23. The locking teeth 22 have an inclined guiding slope 24 facing the notch direction of the receiving groove 23. The top of the locking teeth 22 is provided with an expanded contact part 26. The elastic pressing member 25 is installed on the fixing block 21 and presses on the contact part 26, so that the end of the locking teeth 22 will always be in a state of pressing against the inside of the receiving groove 23.

[0036] Specifically, a fixing hole 702 for connecting with a using implement is formed in the handle part of the blank 700 to be polished, and the engaging teeth 22 are arranged according to this fixing hole 702. Therefore, after the handle of the blank 700 is inserted along the receiving groove 23, the handle part jacks up the engaging teeth 22 along the guiding inclined surface 24. After reaching the part of the fixing hole 702, the engaging teeth 22 are pressed by the elastic pressing member 25 to penetrate into the fixing hole 702 of the blank 700, thereby completing the fixing of the blank 700. In this way, the blank 700 will not fall off during the polishing process. When it is necessary to take out the polished blank 700, the contact part 26 needs to be jacked up first. After being jacked up, the engaging teeth 22 are disengaged from the fixing hole 702, and then the blank 700 can be drawn out.

[0037] Referring to Figure 2 、 Figure 5 and Figure 6 As shown, the angle deflection mechanism 111 includes: a driven gear 31 installed at the end of the fixed block 21, an arc gear 32 rotatably arranged on the outer surface of the installation part 12, the driven gear 31 meshes with the arc gear 32, a dial block 33 is fixedly installed on the outer wall of the arc gear 32, a guide rail 34 is installed on the base 11, a driving block 35 is drivingly installed on the guide rail 34 and is slidably connected with the dial block 33.

[0038] Specifically, all the fixed blocks 21 are kept at the same angle through the meshing of the driven gear 31 and the arc gear 32. When it is necessary to rotate the blank 700 by a certain angle, the guide rail 34 drives the driving block 35 to move, the driving block 35 drives the dial block 33 to deflect, thereby causing the arc gear 32 to rotate. After the arc gear 32 rotates, the fixed block 21 can also rotate accordingly, so that the blank 700 is tilted to the expected tilt angle.

[0039] Referring to Figure 5 and Figure 6 As shown, in order to increase the number of blanks 700 to be polished and further improve the polishing efficiency, two groups of blade fixing units 13 are arranged up and down around the installation part 12 at equal intervals, and at this time the arc gear 32 is placed between the two groups of blade fixing units 13 up and down. Both the upper and lower end faces of the arc gear 32 have teeth, and the driven gears 31 on the blade fixing units 13 arranged on the upper and lower sides both mesh with the arc gear 32. In this way, when the arc gear 32 rotates, the blade fixing units 13 on the upper and lower sides will tilt at the same angle, and the blanks 700 on the blade fixing units 13 at the upper and lower positions can both abut against the arc-shaped grinding part 803 to complete the polishing.

[0040] Referring to Figure 3 、 Figure 7 、 Figure 10 and Figure 11As shown in the figure, the blank extraction mechanism 110 includes: a mounting frame 41 that is movably installed on the first mounting plate 18 by a first driving mechanism and can move in the up-down, left-right directions. Two rubber wheels 42 are symmetrically arranged and rotatably installed on the mounting frame 41. A motor 43 is installed on the mounting frame 41. The motor 43 drives one of the rubber wheels 42 to rotate through a pulley group. After the mounting frame 41 moves down to a certain height, when the gap between the two rubber wheels 42 is flush with the blank 700, the mounting frame 41 moves forward so that the blank 700 is clamped by the two rubber wheels 42. During the process of approaching the blank 700, the end of the separation plate 44 installed on the outer wall of the mounting frame 41 will be inserted under the contact part 26 to lift the contact part 26. As the rubber wheels 42 rotate, the blank 700 can be extracted from the fixed block 21.

[0041] Among them, in order to enable the separation plate 44 to better insert under the contact part 26, the end face of the separation plate 44 in contact with the contact part 26 is an inclined plane. In this way, under the guidance of the inclined plane, the separation plate 44 can better insert under the contact part 26.

[0042] Refer to Figure 3 、 Figures 7-9 As shown in the figure, the feeding mechanism 19 includes: a receiving frame 191 that is driven to lift by a second driving mechanism and installed on the first mounting plate 18. An outlet 192 that only allows a single blank 700 to enter and exit is opened on one side of the bottom of the receiving frame 191. The outlet 192 faces the side of the blade fixing unit 13. An open opening is provided at the top of the receiving frame 191. The blanks 700 to be polished are stacked in the receiving frame 191. The blanks 700 come out one by one from the outlet 192 at the bottom of the receiving frame 191. A first telescopic push rod 193 is installed on the outer wall of the receiving frame 191. A top plate 194 is slidably inserted through the receiving frame 191. The end of the top plate 194 is connected to the first telescopic push rod 193. The thickness of the part of the top plate 194 inserted into the receiving frame 191 is equivalent to the thickness of a single blank 700. Therefore, after the first telescopic push rod 193 pushes the top plate 194, the lowermost blank 700 in the receiving frame 191 will be pushed out. After the outlet 192 is lifted to a suitable height, that is, when the outlet 192 is aligned with the receiving groove 23 on the fixed block 21, the pushed-out blank 700 will be pushed into the receiving groove 23 to achieve the installation of the blank 700.

[0043] Among them, refer to Figure 8As shown in the figure, a convex arc-shaped limiting protrusion 195 is provided on the inner wall of the accommodation frame 191. The arc-shaped limiting protrusion 195 is in line with the blade part of the blank 700. In this way, when placing the blank 700, the blank 700 can only be placed into the accommodation frame 191 at a fixed angle, so as to avoid the situation that the arc-shaped cutting edge 701 of the blank 700 inserted on the fixing block 21 cannot fit with the arc-shaped grinding part 803 due to different placement angles of the blank 700. There is a gap equal to the thickness of the blank 700 between the bottom of the arc-shaped limiting protrusion 195 and the bottom of the accommodation frame 191. The function of this gap is to enable the lowermost blank 700 to slide out normally. If the bottom of the arc-shaped limiting protrusion 195 is directly connected to the bottom of the accommodation frame 191, then the blank 700 cannot slide out of the accommodation frame 191.

[0044] Referring to Figure 7 and Figure 9 As shown in the figure, the second driving mechanism includes: a second telescopic push rod 51 is installed on the first mounting plate 18, first guiding strips 52 are installed on both sides of the accommodation frame 191, a first fixing plate 53 is fixedly installed on the first mounting plate 18, and the first guiding strips 52 are slidably connected to the first fixing plate 53. During use, the second telescopic push rod 51 pushes the accommodation frame 191 to slide in the up and down directions, while the first guiding strips 52 and the first fixing plate 53 provide stable sliding support for the accommodation frame 191.

[0045] Referring to Figure 7 and Figure 10 As shown in the figure, the first driving mechanism includes: second guiding strips 61 symmetrically arranged on both sides of the mounting frame 41, guiding plates 63 are slidably connected to both sides of the second mounting plate 62, the guiding plates 63 are fixedly installed on the first mounting plate 18, the second guiding strips 61 are slidably installed on the second mounting plate 62, a first electric push block 64 is installed on the first mounting plate 18 and drives the second mounting plate 62 to slide, and a second electric push block 65 is installed on the second mounting plate 62 and drives the mounting frame 41 to move up and down. During use, the first electric push block 64 can pull the second mounting plate 62 to move horizontally, so as to make the mounting frame 41 approach or move away from the fixing block 21, while the second electric push block 65 pushes the mounting frame 41 to lift in the up and down directions, so as to make the gap between the two rubber wheels 42 flush with the blank 700.

[0046] The above-described embodiments only represent the preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations, improvements and substitutions can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
