The negative pressure bearing device has the beneficial effects that negative pressure is applied to the position of the falling point of the metal gasket on the carrier tape from multiple directions, so that the smoothness of the carrying area of the metal gasket can be further ensured.

In some embodiments, the metal shim is circular, oval, "D" shaped, or other symmetrical shape. The metal gasket packaging machine has the advantages of being suitable for transmission packaging of metal gaskets in various common shapes, and expanding the application range.

In some embodiments, the plurality of suction holes are symmetrically disposed along a centerline of the carrier product carrying zone. The negative pressure conveying device has the beneficial effects that when the metal gasket in a circular shape, an oval shape, a D shape or other symmetrical shapes is conveyed, symmetrical negative pressure is applied to the position of a drop point on the carrier tape of the metal sheet, so that the uniform stress of each position of the drop point is ensured, and the stability is ensured.

In some embodiments, the metal gasket is a steel, copper or aluminum sheet. The metal gasket has the beneficial effects that the metal gasket can be suitable for metal gaskets made of various common materials, and the application market is wide. The metal gasket may be other materials besides steel, copper or aluminum, such as nickel-copper alloy, etc.

In some embodiments, the carrier tape has a pocket depth of no more than 0.3mm and the carrier tape is paper. The belt-carrying mold cavity has the advantages that the technical improvement can be carried out on the basis of a general belt-carrying mold cavity, new equipment does not need to be designed and processed, the processing technology is mature, and the cost can be reduced.

In some embodiments, the metal shim has a thickness of no more than 0.15 mm. Therefore, the metal gasket is suitable for the transmission package of most metal gaskets in the market and has wide application market.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example 1

The metal gasket 3 is widely used in electronic products and mechanical appliances, and in the packaging process of the metal gasket 3, a large number of metal gaskets 3 are usually uniformly adhered to a paper coiled material, and then a covering film is covered on the paper coiled material for protection. Therefore, the metal gasket 3 can be conveniently packaged and transported and can be conveniently taken and used.

Fig. 1 and 2 schematically show a method of packaging a metal gasket according to an embodiment of the present invention. The metal gasket 3 is a steel sheet and is in a D shape, the metal gasket 3 can be processed and formed in a stamping or die cutting mode, and the thickness is 0.15 mm. The D-shaped steel sheet is suitable in thickness and convenient to take. The metal gasket 3 formed by processing is directly blanked on the paper carrier tape 22, and the carrier tape 2 is conveyed in the carrier tape cavity 1.

The depth of the carrier tape cavity 1 is 0.3mm, a plurality of air suction holes 11 are formed in the bottom of the carrier tape cavity 1, and uniform negative pressure is applied to the bottom of the carrier tape 2 through the air suction holes 11, so that the carrier tape 2 is attached to the bottom of the carrier tape cavity 1 under the action of the negative pressure. The carrier tape 2 is made of paper, and two side edges of the carrier tape 2 are a packaging and waste discharging area 22, and the middle is a product carrying area 21. The metal gasket 3 can be dropped in the center position of the product carrying area 21. The plurality of suction holes 11 face the product carrying area 21 on the carrier tape 2 and are arranged in two lines in the running direction of the carrier tape 2. The suction holes 11 on the two straight lines are symmetrically arranged two by two along the center line of the product carrying area 21.

The drop point area of the D-shaped metal gasket 3 on the paper carrier tape 2 can simultaneously cover two air suction holes 11 which are symmetrical left and right, and as shown in fig. 2, the positions of the metal gasket 3 covering the two air suction holes 11 are also symmetrical. Negative pressure is applied to the bottom of the carrier tape 2 through the air suction holes 11, the carrier tape 2 can be tightly attached to the carrier tape cavity 1, and the whole carrier tape 2 is kept flat and free of wrinkles in the conveying process. After the metal gasket 3 falls on the carrier band 2, the stress is uniform and the dislocation is avoided.

After the metal gasket 3 is separated from the carrier tape cavity 1, a covering film is covered on the metal gasket 3 for sealing, so that the protection is enhanced. Because the air suction holes 11 are formed in the carrier tape cavity 1 and negative pressure is applied in a combined mode, the metal gasket 3 cannot deviate, when a cover film is covered, the blanking position of the metal gasket 3 is still kept, subsequent cutting processing or use cannot be influenced, and the sealing yield of products can be improved.

Example 2

In this embodiment, metal gasket 3 is the copper sheet, and the shape is the ring shape, and metal gasket 3 can adopt the mode machine-shaping of punching press or cross cutting, and thickness is 0.1mm, and thickness is thinner, is applicable to more meticulous product processing. The metal gasket 3 formed by processing is directly blanked on the paper carrier tape 22, and the carrier tape 2 is conveyed in the carrier tape cavity 1.

The depth of the carrier tape cavity 1 is 0.25mm, a plurality of air suction holes 11 are arranged at the bottom of the carrier tape cavity 1, two sides of the carrier tape 2 are packing and waste discharging areas 22, and the middle part is a product carrying area 21. The metal gasket 3 can be dropped in the center position of the product carrying area 21. The plurality of suction holes 11 face the product carrying area 21 on the carrier tape 2, are arranged in three straight lines along the running direction of the carrier tape 2, wherein one straight line is superposed with the central line of the product carrying area 21, the other two straight lines are symmetrically arranged along the central line of the product carrying area 21, and the suction holes 11 are also symmetrically arranged along the central line of the product carrying area 21.

The circular ring-shaped metal gasket 3 can cover four suction holes 11 simultaneously in the drop point area of the paper carrier tape 2, and the four suction holes 11 are symmetrical along the center line of the product carrying area 21. The four areas of the circular metal gasket 3 covering the air suction holes 11 are also symmetrical to each other and are uniformly distributed on the circular ring of the metal gasket 3. Negative pressure is applied to the bottom of the carrier tape 2 through the air suction holes 11, the carrier tape 2 can be tightly attached to the carrier tape cavity 1, and the whole carrier tape 2 is kept flat and free of wrinkles in the conveying process.
