Background art:
annular metal sheets with extremely small sizes are sometimes required to be assembled in electronic elements in electronic products such as mobile phones and tablet personal computers, the outer diameter of each annular metal sheet is as small as 1-2mm, the inner diameter of each annular metal sheet is as small as 0.5-1.5mm, even smaller, and the thickness of each annular metal sheet is also millimeter level; obviously, the taking, placing, assembling and the like of such tiny and thin articles are troublesome, at present, when the products are assembled, the articles can be clamped, transferred and assembled only by using finer tweezers, the operation needs to be very careful, and even the articles can be assembled only by using auxiliary appliances such as a magnifier, so that the defects of inconvenient operation, low assembling efficiency, low precision and the like exist.
The utility model has the following contents:
the utility model aims at overcoming the above-mentioned weak point of prior art, provide a tool is absorb to small annular sheetmetal.
The utility model adopts the technical proposal that: a tiny annular metal sheet suction jig is provided with a holding rod main body, wherein the lower part of the holding rod main body is provided with an inverted cone-shaped part, and the bottom end of the inverted cone-shaped part is formed with a columnar part; an inverted cone-shaped outer sleeve connected with the holding rod main body is further mounted on the periphery of the inverted cone-shaped portion, an airflow gap is formed between the inner wall of the inverted cone-shaped outer sleeve and the outer wall of the inverted cone-shaped portion, and an air exhaust channel communicated with the airflow gap is arranged in the holding rod main body; an annular gap is formed between the opening at the bottom end of the inverted conical outer sleeve and the columnar part.
The end part of the columnar part protrudes out of the bottom end part of the inverted cone-shaped outer sleeve, and the protruding distance is just equal to the thickness of the metal sheet.
The air exhaust channel is arranged along the axial direction of the holding rod main body, and the lower part of the air exhaust channel is communicated with the air flow gap through a radial hole.
The periphery of the end face of the columnar part forms a chamfer face.
The upper end part of the holding rod main body is provided with a quick joint communicated with the air exhaust channel.
The utility model discloses the tool is particularly suitable for the absorption of the minimum millimeter level annular sheetmetal of size, shifts and paste operations such as equipment, is favorable to raising the efficiency and assembles the precision, and this tool still for follow-up sustainable development and cooperate the manipulator to realize automatic subsides dress technology and provide the basis.
Description of the drawings:
fig. 1 is an exploded view of the jig of the present invention;
fig. 2 is a cross-sectional view of the present invention;
fig. 3 is a partially enlarged view of fig. 2.
The specific implementation mode is as follows:
as shown in fig. 1, 2 and 3, the utility model relates to a small annular metal sheet suction jig for sucking thin sheet products with extremely small size, such as steel sheets, etc., the suction jig is provided with a holding rod main body 1, the holding rod main body 1 is in a pen shape, the lower part of the holding rod main body 1 is provided with an inverted cone-shaped part 11, and the bottom end of the inverted cone-shaped part 11 is formed with a column-shaped part 12; the periphery of the inverted conical part 11 is also provided with an inverted conical outer sleeve 2 connected with the holding rod main body 1, and the upper end part of the inverted conical outer sleeve 2 is assembled with the lower part of the holding rod main body 1 in a butt joint way; an air flow gap 201 is formed between the inner wall of the inverted cone-shaped outer sleeve 2 and the outer wall of the inverted cone-shaped part 11, and an air extraction channel 101 communicated with the air flow gap 201 is arranged in the holding rod main body 1; an annular gap 202 for adsorbing annular metal sheets is formed between the opening at the bottom end of the inverted conical outer sleeve 2 and the columnar part 12; the inner diameter of the annular gap 202, i.e. the outer diameter of the column part 12, is slightly smaller than the inner diameter of the annular metal sheet, so that the column part 12 can penetrate into the annular metal sheet conveniently, and the outer diameter of the annular gap 202 is smaller than the outer diameter of the annular metal sheet, i.e. the annular metal sheet can seal the annular gap 202, so that negative pressure is generated in the annular gap 202 during air suction, and the annular metal sheet is adsorbed.
The air is connected with external vacuum pumping equipment through an air pumping channel 101 for air pumping, and air flow is sucked from the annular gap 202 at the bottommost part to generate negative pressure; the columnar part 12 is inserted into the central hole of the annular metal sheet to be sucked, the annular metal sheet is adsorbed at the annular gap 202 under the action of the suction negative pressure, so that the annular metal sheet can be conveniently transferred to a part to be placed, after the annular metal sheet is in place, the suction is stopped, and the annular metal sheet automatically falls under the action of the gravity of the annular metal sheet, so that the annular metal sheet is adhered or positioned on the part to be placed.
Preferably, the end of the column part 12 protrudes from the bottom end of the inverted cone-shaped outer sleeve 2 by a distance just corresponding to the thickness of the metal sheet; the periphery of the end face of the columnar part 12 forms a chamfer face, so that the columnar part 12 can be conveniently inserted into a central hole of the annular metal sheet, and the rapid positioning and the absorption are realized;
the air extracting channel 101 is arranged along the axial direction of the grip rod main body 1, and the lower part of the air extracting channel 101 is communicated with the air flow gap 201 through the radial hole 102;
the upper end part of the holding rod main body 1 is provided with a quick connector 3 communicated with the air exhaust channel 101, so that the quick connector can be connected with and detached from a pipeline of air exhaust equipment conveniently.
To sum up, the utility model discloses the tool is particularly suitable for the absorption of the minimum millimeter level annular sheetmetal of size, shifts and paste operations such as equipment, is favorable to raising the efficiency and assembles the precision, and this tool still for follow-up sustainable development and cooperate the manipulator to realize automatic surface mounting technology and provide the basis.
