The following describes embodiments of the present utility model in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1 to 6, an embodiment of the present utility model discloses a material taking device 100 for taking and placing a material piece, so as to facilitate assembly of the material piece. The disclosed reclaimer 100 includes an adsorption mechanism 110, the adsorption mechanism 110 being configured to adsorb or release material pieces.

The adsorption mechanism 110 includes a sleeve 111 and a thimble 112 movably disposed within the sleeve 111, wherein the sleeve 111 includes a first channel 1111 and a second channel 1112, and the first channel 1111 and the second channel 1112 are in communication with each other. In an actual condition, the adsorption mechanism 110 extends in the up-down direction, the first channel 1111 is located above, the second channel 1112 is located below, and an end of the second channel 1112 facing away from the first channel 1111 (i.e. the adsorption end of the sleeve 111) may be used for adsorbing the material. Of course, the adsorption mechanism 110 may also extend in the left-right direction or the front-rear direction, and may be specifically set according to the actual working conditions.

The ejector pin 112 includes a first needle section 1121 and a second needle section 1122, wherein the first needle section 1121 is disposed corresponding to the first channel 1111 and the second needle section 1122 is disposed corresponding to the second channel 1112. Illustratively, a first needle segment 1121 may be disposed within the first channel 1111, a second needle segment 1122 may be disposed within the second channel 1112, and the entirety of the needle 112 may be movable within the first and second channels 1111, 1112 to facilitate pushing of the material at the suction end, such that the pushed material is separated from the suction end of the sleeve 111.

In order to enable a negative pressure zone near the suction end for the suction of the material, the side wall of the sleeve 111 may be provided with a suction hole 1113, which suction hole 1113 communicates with the second channel 1112, so that the end of the second channel 1112 facing away from the first channel 1111 generates a negative pressure for the suction of the material. In some embodiments, the suction hole 1113 may be used to connect with an external suction device, where the suction device may include a vacuum pump, etc., and under the action of the suction device, the gas in the second channel 1112 may be pumped through the suction hole 1113, so that a certain vacuum degree is generated in the second channel 1112, and a negative pressure area is formed near the suction end, so as to facilitate the suction of the material piece.

With the portion of spike 112 (i.e., second needle segment 1122) disposed in second passageway 1112, to avoid obstruction of the vacuum draw by second needle segment 1122, an air passageway may be formed between the inner wall of second passageway 1112 and the outer wall of spike 112, which air passageway communicates with suction orifice 1113 such that the air within second passageway 1112 may flow along the air passageway to suction orifice 1113 and be drawn through suction orifice 1113.

Because first channel 1111 communicates with second channel 1112 and another portion of spike 112 (i.e., first needle segment 1121) is disposed in first channel 1111 and is movable along first channel 1111, in order to ensure that no leakage between first needle segment 1121 and first channel 1111 will occur and that vacuum may be effected, in the present embodiment, the cross-sectional area of first channel 1111 is equal to or slightly greater than the cross-sectional area of first needle segment 1121, such that a sliding seal connection between first needle segment 1121 and first channel 1111 is enabled.

In some embodiments, the cross-sectional areas of the first needle segment 1121 and the second needle segment 1122 may be equal, and the cross-sectional area of the second channel 1112 is larger than the cross-sectional area of the first channel 1111, so that the movement of the ejector pin 112 in the first channel 1111 and the second channel 1112 may be ensured, and a sealing effect between the outer wall of the first needle segment 1121 and the inner wall of the first channel 1111 may be achieved, so as to prevent the air leakage in the gap between the outer wall of the first needle segment 1121 and the inner wall of the first channel 1111, and affect the adsorption effect on the material.

In other embodiments, the cross-sectional area of first needle segment 1121 may be greater than the cross-sectional area of second needle segment 1122, and the cross-sectional areas of first channel 1111 and second channel 1112 may be equal, such an arrangement may ensure a sliding sealed connection between first needle segment 1121 and first channel 1111, and may also ensure a gap between second needle segment 1122 and second channel 1112 to facilitate evacuation.

For example, the cross-sections of the first channel 1111, the second channel 1112 and the thimble 112 may be circular, in which case the radius of the first channel 1111 and the radius of the first needle segment 1121 may be equal, and of course, a certain radius difference may exist, so that a preset gap exists between the two, for example, the difference between the radius of the first channel 1111 and the radius of the first needle segment 1121 is 0.1mm, which may, of course, be other values, which are not limited herein specifically.

In the embodiment of the utility model, the air in the air passage formed between the second channel 1112 and the second needle section 1122 can be pumped out through the pumping hole 1113, so that a negative pressure area is formed at one end of the second channel 1112, which is far away from the first channel 1111, and therefore, the material can be adsorbed, and the subsequent transmission of the material is facilitated; when the material is transferred to the preset position, the suction action is stopped, and the ejector pin 112 is moved along the direction from the first channel 1111 to the second channel 1112, so that the material can be extruded, the material is pushed to be separated from the sleeve 111, and the release of the material is realized. The material taking device 100 can take materials in a vacuum adsorption mode, and can push the material through the ejector pin 112 during material taking, so that the material is separated from the sleeve 111, the material can be prevented from being adhered to the end part of the sleeve 111 to influence material taking, and the smoothness of material taking is ensured.

To enable movement of needle 112 in first and second channels 1111, 1112, in some embodiments, cannula 111 may further include a movement cavity 1117, the movement cavity 1117 communicating with first channel 1111, and needle 112 may further include a movement section 1123 coupled to first needle section 1121, movement section 1123 positioned within movement cavity 1117; the side wall of the sleeve 111 is further provided with a first air hole and a second air hole, wherein the first air hole is communicated with the moving cavity 1117, the second air hole is located in a position, adjacent to the moving cavity 1117, of the first channel 1111 and is communicated with the first channel 1111, so that the first air hole and the second air hole can be located at two sides of one end, located in the moving cavity 1117, of the thimble 112 respectively.

Based on the above arrangement, under the condition that the compressed gas is introduced into the first air hole, the ejector pin 112 can move along the direction from the first channel 1111 to the second channel 1112 under the pressure of the compressed gas, so that the material piece at the adsorption end of the sleeve 111 can be ejected out, and the material piece is quickly separated from the adsorption end without adhesion; to prevent excessive pressure on the side of movement cavity 1117 adjacent to the second vent from affecting movement of spike 112, pressure relief may be performed through the second vent. Under the condition that compressed gas is introduced into the second air hole, the ejector pin 112 can move along the direction from the second channel 1112 to the first channel 1111 under the pressure action of the compressed gas, so that the other end of the ejector pin 112 can retract into the second channel 1112 relative to the adsorption end, and the other end of the ejector pin 112 is prevented from affecting the adsorption action on the next material; to prevent excessive pressure on the side of mobile cavity 1117 adjacent to the first port from affecting movement of spike 112, pressure relief may be performed through the first port.

Illustratively, the moving section 1123 may be a bump structure slidably and sealingly connected to the moving cavity 1117, where the first air hole is located above the bump structure and the second air hole is located below the bump structure, so that after the compressed air is introduced into the first air hole, a pressure is generated on the upper surface of the bump structure to push the ejector pin 112 to move downward and push the material out; after the compressed gas is introduced into the second air hole, a pressure is generated on the lower surface of the bump structure, so as to push the ejector pin 112 to move upwards, and the other end of the ejector pin 112 is retracted into the second channel 1112.

In other embodiments, other means may be used to drive the movement of spike 112 in first channel 1111 and second channel 1112, such as, for example, a pneumatic cylinder, an electric cylinder, etc., without limitation.

Referring to fig. 2, in some embodiments, the first air hole may be an air inlet hole 1114, and the second air hole may be an air outlet hole 1115, in which case, compressed air may be introduced into the moving cavity 1117 through the air inlet hole 1114, so as to push the ejector pin 112 to move in a direction from the first channel 1111 to the second channel 1112, so as to push the material to separate from the adsorption end of the sleeve 111, and at the same time, part of air in a side of the moving cavity 1117 close to the air outlet hole 1115 may be discharged through the air outlet hole 1115, so as to prevent the air pressure in the area from being too high to affect the movement of the ejector pin 112.

After the material piece at the adsorption end of the sleeve 111 is pushed out, in order to ensure that the next material piece can be adsorbed normally, the other end of the ejector pin 112 needs to retract into the second channel 1112.

Wherein, the partial area of the first channel 1111 adjacent to the moving cavity 1117 and the first needle segment 1121 form an annular cavity, and the elastic element 113 is located in the annular cavity, and the annular cavity can provide a receiving space for the elastic element 113. In addition, the elastic element 113 is sleeved outside the first needle section 1121, one end of the elastic element 113 is connected with the bottom wall of the annular cavity, and the other end of the elastic element 113 is connected with the moving section 1123. With this arrangement, after stopping the compressed air from flowing into the air inlet 1114, the ejector pin 112 can be pushed by the elastic element 113 to retract.
