Detailed Description

The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.

Referring to fig. 1 to 4, an embodiment of a positioning device according to the present invention includes a first body 1 and a second body 3 disposed opposite to the first body 1, and a transfer passage 31 is formed between the first body and the second body 3. When the first body 1 and the second body 3 are mated, the first body 1 can be laid over the transfer channel 31 and the material 6 can be moved to a desired position through the transfer channel 31. The free end of the conveying channel 31 for the placement of the material 6 is defined as the channel end, at the location of which a fine positioning structure is arranged. The first body 1 and the second body 3 are oppositely arranged in the vertical direction in the present embodiment, so that the material 6 is more easily embedded in the conveying passage 31 by using the gravity of the material 6 itself.

The first body 1 and the second body 3 are disposed opposite to each other in the vertical direction in this embodiment, and the inclined portion 2 is opened on the surface of the first body 1 near the second body 3, and the inclined portion 2 is disposed near the conveying passage 31 in this embodiment. The inclined part 2 comprises a first end 21 and a second end 22 at both ends, the end near the conveying channel 31 being referred to as the first end 21 in this embodiment and the end near the free end of the first body 1 being referred to as the second end 22. The perpendicular distance of the first end 21 with respect to the surface of the second body 3 is greater than the perpendicular distance of the second end 22 with respect to the surface of the second body 3. Since the first end 21 is at a distance from the surface of the second body 3 and the first end 21 is arranged close to the transfer channel 31, a space is also formed between the material 6 and the first end 21 when the material 6 has moved to the desired position. So that the material 6 is not easy to be clamped between the conveying channel 31 and the first main body 1, and the position of the material 6 can be further adjusted conveniently.

The inclined portion 2 is adapted to abut the upper end of the material 6 when the first body 1 and the second body 3 are relatively moved, thereby applying pressure to the material 6 to bring the material 6 to a precisely positioned position. When first

main part

1 and 3 relative motion of second main part, both need to guarantee that rake 2 can press and establish on material 6, make it get into smart position, also need to guarantee that material 6 that is located smart position can expose for first main part 1 to material 6 is shifted to in the next process. It is thus possible to provide for the first body 1 to move alone, the second body 3 to move alone, it is also possible to provide for the first body 1 and the second body 3 to move in opposite directions simultaneously.

The inclined part 2 can be a plane or a curved surface, and in the embodiment, the inclined part 2 is a plane, so that the cost of processing is lower compared with the cost of a curved surface.

The second end 22 is disposed near the free end of the first body 1, and the free end of the first body 1 is chamfered in this embodiment. The transition from the inclined part 2 to the free end is realized by utilizing the chamfer, and when the first main body and the second main body are reset, the free end of the first main body can be ensured to smoothly cross over the conveying channel.

To material 6 that materials such as screw are lighter, anchor clamps are mostly metal material among the prior art, therefore metal material is easily taking place the magnetization at the in-process of carrying, therefore because magnetic adsorption makes metal material easily adsorb in anchor clamps, therefore prior art can't realize the location at the in-process that metal material carried. In addition, in order to ensure the fit between the metal material and the clamp in the prior art, the metal material is mostly positioned relative to the clamp by adopting magnetic adsorption or airflow negative pressure adsorption and other modes at the positioning part. But the parameters such as the magnitude and the direction of the magnetic adsorption force are complex and uncontrollable. Meanwhile, in the metal material transportation process, a gap may exist between the metal material and the clamp, and the acting force is difficult to control when the air flow negative pressure adsorption is easily caused, so that the metal material in the prior art cannot be accurately positioned in the transportation process.

In further preferred scheme, be provided with locating part 4 on the first main part 1, utilize above-mentioned locating part 4 butt material 6 for material 6 can realize preliminary location when the transfer passage 31 internal motion, the relative motion that also is convenient for the later stage to utilize first main part 1 and second main part 3 realizes the fine positioning. In the present embodiment, the limiting member 4 is disposed along the opening direction of the conveying channel 31, the limiting member 4 includes a pressing portion 41 at a free end thereof, and the pressing portion 41 is disposed near a predetermined positioning position of the material 6. The pressing portion 41 is obliquely arranged in a direction close to the free end thereof so that the free end of the pressing portion 41 is located on the moving path of the material 6. When the material 6 moves along the conveying channel 31, the material 6 contacts the inclined pressing part 41 when moving to the position below the pressing part 41 close to the free end of the limiting part 4, and the pressing part 41 is pushed away from the channel, so that the material can continuously advance to cross the pressing part 41 to reach a preset positioning position. When the material reaches the preset positioning position, the pressing part 41 is reset, the free end of the pressing part returns to the moving channel of the material 6, and at the moment, if the material 6 moves back under the action of the rebounding force, the free end of the pressing part 41 resists the material 6, so that the material is kept at the preset position.

The limiting part 4 is an elastic part, when the material moves to the preset position, the free end of the limiting part 4 can be pushed away from the channel by the material, and after the material reaches the preset position, the free end resets under the action of the elasticity, and the unidirectional movement of the material is realized. The predetermined position is between the end of the conveying channel and the free end of the elastic element, which limits the mass 6 within the range of positions in which the subsequent fine positioning can be performed.

Through the matching of the limiting part 4 and the inclined part 2, the materials 6 can be roughly positioned in the process that the materials 6 move along the conveying channel 31; then when the material 6 moves to the inclined part 2, the material 6 is further finely positioned by the inclined part 2 by the relative movement between the first body 1 and the second body 3. The position of the material 6 does not need to be adjusted through extra processes and steps in the process of conveying the material 6, so that the position precision of the material 6 in the conveying process can be improved, and the conveying of the material 6 is more easily matched with the processing requirements of streamlined and mechanized operation. And in the example, the rough positioning and the fine positioning of the material 6 are related and matched, and the setting of the limiting part 4 and the setting of the inclined part 2 are matched with each other by referring to relevant parameters of the material 6.

Since the first body 1 is connected to the second body 3 by the elastic member 11, the second body 3 can push the first body 1 to move synchronously by the elastic member 11 when the second body 3 moves by the driving member 32. In this movement phase, the first body 1 and the second body 3 enclose the material 6 in the closed cavity, preventing the material 6 from falling off. Because the limiting assembly is arranged between the first main body 1 and the base 5, when the first main body 1 moves to the position of the limiting assembly, the first main body 1 stops moving under the blocking of the limiting assembly, the driving piece 32 continues to push the second main body 3 to move, and at the moment, the elastic piece 11 positioned between the first main body 1 and the second main body 3 is in a continuously compressed state, so that the second main body 3 can move relative to the first main body 1 under the action of the driving piece 32, and the material 6 placed at the coarse positioning position is precisely positioned. The elastic member 11 in this embodiment is preferably a coil spring.

The stop assembly comprises a projection 12 and an abutment 51 for abutting against the projection 12, the projection 12 being provided on a side wall of the first body 1 in this embodiment, the abutment 51 being provided on an upper surface of the base 5. When the second body 3 continues to push the first body 1 by the elastic member 11 after the first body 1 moves to the position where the projection 12 and the butting portion 51 abut, the second body 3 can move relative to the base 5. In order to make the distribution of the pushing force exerted on the first body 1 by the butting portion 51 more uniform in the present embodiment, the limiting components are symmetrically arranged in the present embodiment.

The second body 3 is connected to the base 5 through a sliding member 52, in this embodiment, the sliding member 52 is preferably a linear slide rail and a slide block matched with the linear slide rail, wherein the slide rail is fixedly arranged on the base 5, and the slide block is connected to the lower surface of the second body 3. The sliding piece 52 can limit the moving direction of the second body 3, and the precision of the materials 6 in transportation is improved.

The first body 1 is connected with the second body 3 through a fastening piece 13, and a sliding groove 14 matched with the fastening piece 13 is formed in the first body 1 in a penetrating manner, in this example, the fastening piece 13 can be embedded in the sliding groove 14 to move, and the fastening piece 13 can be a fastening bolt or the like. The first body 1 and the second body 3 are connected by the fastening member 13, so that the first body 1 can be pushed to move by the second body 3, and the fastening member 13 can limit the displacement of the first body 1 along the vertical direction, thereby ensuring that the position of the inclined part 2 relative to the material 6 is more accurate. When the protruding portion 12 abuts against the abutting portion 51, the first main body 1 is fixed relative to the base 5, and when the second main body 3 is driven to move, the fastening member 13 can be embedded in the sliding groove 14 to move, so that the second main body 3 and the first main body 1 move relatively. The direction in which the second body 3 moves relative to the first body 1 can also be restricted by the slide groove 14 provided in the first body 1.
