DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0037] The directional and positional terms used in this invention, such as up, down, front, back, left, right, inside, outside, top, bottom, and side, are merely references to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0038] A material stepping conveying device, such as Figure 1-4 As shown, it includes a frame 1, a positioning fixture 2, a fixture guide rail 3, a fixture stepping push assembly, and a drive mechanism. In the accompanying drawings, the frame 1 only shows a partial structure. It is understandable that the frame 1 also includes at least a structure for fixing the drive mechanism.

[0039] The structure of the positioning fixture 2 is as follows Figure 2As shown, its upper end is provided with a number of positioning structures 201 arranged sequentially along the conveying direction for fixing, and its lower end is provided with push grooves 202 corresponding to the number and position of the positioning structures 201. The specific arrangement of the positioning structures 201 is designed according to the material being conveyed. The structure shown in the figure is a positioning structure 201 arranged according to the structure of the coil bobbin. The clamp guide rail members 3 are provided with two, and their adjacent surfaces are provided with limited conveying tracks 301. The positioning clamp 2 is provided with sliding protrusions 203 on both sides that cooperate with the limited conveying tracks 301. The positioning clamp 2 is limited between the clamp guide rail members 3, allowing it to move as much as possible along the guide rail direction.

[0040] like Figure 5 As shown, the fixture stepping push assembly is fixed on the frame 1 and is located below the fixture guide rail member 3, including a first rail member 4, a first sliding block 5, a one-way push block 6, and a torsion spring. The first rail member 4 is fixed on the frame 1. The first rail member 4 and the first sliding block 5 cooperate so that the first sliding block 5 can only slide linearly along the first rail member 4. The one-way push block 6 is hingedly connected to the first sliding block 5 and its upper end is raised relative to the upper end of the first sliding block 5 so that it is inserted into the push groove 113. The one-way push block 6 The upper end has a vertical surface 601 and an action inclined surface 602 on both sides. The first sliding block 5 is provided with a limit pin 505 located on one side of the vertical surface 601 to limit the vertical surface 601. The one-way push block 6 can rotate to have a first position where the vertical surface 601 is vertical or nearly vertical and abuts the limit pin 505 and a second position where the vertical surface 601 is away from the limit pin 505. The torsion spring acts on the first sliding block 5 to move it toward the first position; the driving mechanism is used to drive the first sliding block 5 to reciprocate along a straight line. Figure 5 As shown, the first sliding block 5 slides to the right, and the vertical surface 601 cooperates with the bottom of the positioning fixture 2, driving the positioning fixture 2 to move one position to the right, and then the first sliding block 5 moves to the left to reset. During the reset process, the active inclined surface 602 cooperates with the bottom of the positioning fixture 2, causing the one-way push block 6 to rotate clockwise, so it will not drive the positioning fixture 2, and then reset into the next push groove 113 under the action of the torsion spring.

[0041] like Figure 6 As shown, at least one roller mounting groove 302 is provided in the position-limiting conveying track 301 of the fixture guide member 3. A roller bracket 7 is mounted in the roller mounting groove 302. A first roller 8 is rotatably connected to the roller bracket 7. The side surfaces of the positioning fixture 2 are clearance-matched with the bottom surface of the position-limiting conveying track 301. The first roller 8 is raised relative to the bottom surface of the position-limiting conveying track 301 so that its circumference is in contact with the side surface of the positioning fixture 2. This arrangement reduces friction when the fixture guide member 3 moves.

[0042] Furthermore, the roller bracket 7 is slidable relative to the fixture guide rail 3, and a first compression spring 9 is provided to act on the roller bracket 7 to impart a thrust toward the positioning fixture 2. The sliding protrusion 203 is provided with positioning slots 204 corresponding in number and position to the positioning structures 201. The first roller 8 cooperates with the positioning slots 204 to achieve stepwise positioning of the positioning fixture 2. When the force exerted on the positioning fixture 2 is insufficient, the positioning fixture 2 will not overcome the thrust of the first compression spring 9 and move.

[0043] Further, such as Figure 7 As shown, the roller bracket 7 is provided with two hinged plates 701, which are respectively located on the upper and lower sides of the first roller 8 and are rotatably connected to the first roller 8 through the first connecting shaft 10. The two ends of the first connecting shaft 10 are protruding relative to the two hinged plates 701 of the roller bracket 7, and the clamp guide rail member 3 is provided with a limiting strip groove 303 on the upper and lower sides of the roller bracket 7 for the first connecting shaft 10 to extend into.

[0044] The structure of the fixture stepping push assembly is as follows Figure 8 As shown, the first sliding block 5 includes a sliding body 501 provided with a track groove, and a mounting frame 502 connected to the upper end of the sliding body 501, the mounting frame 502 has two oppositely arranged connecting side plates 503, the one-way push block 6 is arranged between the two connecting side plates 503 and connected through a second connecting shaft 504, and the two ends of the limit pin 505 are respectively fixed on the two connecting side plates 503.

[0045] Preferably, a bearing 11 is provided between the one-way push block 6 and the second connecting shaft 504 to reduce the resistance during rotation relative to the first sliding block 5, and to prevent the action inclined surface 602 from cooperating with the bottom of the positioning fixture 2 to cause excessive thrust for the clockwise rotation of the one-way push block 6, thereby driving the positioning fixture 2 to move slightly.

[0046] The first track member 4 has a wire limit plate 401, and the first sliding block 5 has a wire fixing plate 506. An elastic member is provided to form a force on the first sliding block 5 in the conveying direction; the driving mechanism includes a wire 13, and a wire sleeve 20 is provided on the outer shell of the wire 13. The two ends of the wire sleeve 20 are limited. The wire 13 passes through the wire limit plate 401 and is fixedly connected to the wire fixing plate 506. By pulling the wire 13, the first sliding block 5 is caused to slide back and forth along the conveying direction in cooperation with the elastic member. In this embodiment, the elastic member is specifically a second compression spring arranged between the wire limit plate 401 and the wire fixing plate 506. It is not shown in the figure, but those skilled in the art can understand its specific cooperation structure. In this embodiment, the two ends of the wire sleeve 20 are respectively against the frame 1 and the wire limit plate 401. When the wire 13 is pulled, the wire 13 will move in the wire sleeve 20, pulling the first sliding block 5 to move a preset distance. Through the structure of the pull wire 13 , the installation position of the driving mechanism is not limited to the position of the first sliding block 5 , and does not need to be installed in a limited area below the fixture guide rail member 3 .

[0047] like Figure 5 As shown, the frame 1 is connected to a limit plate 12, and the fixture guide member 3 is located above the limit plate 12. The limit plate 12 is provided with a limit opening 1201, through which the mounting bracket 502 passes, limiting its sliding travel to the limit opening 1201. The limit plate 12 limits the leftward movement limit position of the elastic member of the first sliding block 5, thereby ensuring the stepping distance.

[0048] The driving mechanism includes a rotary motor 14, a rotary shaft 15, a second track member 16, and a second sliding block 17. The rotary shaft 15 is connected to the output end of the rotary motor 14, and the second track member 16 is fixed to the frame 1. Figure 9 As shown, the second sliding block 17 cooperates with the second track member 16 so that it can only slide axially along the rotating shaft 15. A sliding guide groove 1501 is provided on the outer periphery of the rotating shaft 15. The second sliding block 17 is connected to a second roller 1701 located in the sliding guide groove 1501. During the circumferential rotation of the rotating shaft 15, the second roller 1701 cooperates with the sliding guide groove 1501 to enable the second sliding block 17 to slide back and forth axially along the rotating shaft 15.

[0049] The other end of the pull wire 13 opposite to the pull wire fixing plate 506 is fixedly connected to the second sliding block 17 .

[0050] It also includes a clamp aisle 18 and a clamp push rod 19. The clamp aisle 18 is connected to the conveying front end of the clamp guide rail 3 and is provided with a limiting groove 1801 for accommodating the positioning clamp 2. The clamp push rod 19 is connected to the conveying front end of the clamp aisle 18 and is used to push the positioning clamp 2 in the limiting groove 1801 to between the two clamp guide rails 3.

[0051] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
