Background
Needle-like products are used in many fields, for example, PIN needles used in the electronic industry have various morphological specifications, and therefore, it is very important to realize accurate and efficient sorting and classification after the needle-like products are produced. At present, in the screening process of needle-shaped products such as PIN needles and the like, an integrated needle plate is generally adopted, a tunnel structure with a single specification is arranged on the needle plate, and the products corresponding to the tunnel specification can be screened out. The disadvantage of this approach is that one needle plate can only screen one format of product and does not have the ability to achieve automatic sorting to distinguish between other formats (diameter formats). When products of various specifications are mixed together, a large number of needle plates are needed for screening, so that not only is higher cost consumed, but also the screening efficiency cannot meet the requirement.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is the defect of prior art, provide a structural design more reasonable, the screening efficiency is higher, can utilize the tunnel to screen the device of two kinds of different specification needle-like products at least simultaneously, especially indicate the screening faller.
In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides an utilize device of different specification needle-like products of tunnel screening, including the base plate, its characterized in that: a plurality of screening grooves capable of accommodating needle-shaped products to pass through are arranged on the base plate, and at least one screening hole is arranged in each screening groove; the length of the screening hole is smaller than that of the screening groove, and the width of the screening hole is smaller than that of the screening groove, so that a structure that needle-shaped products with the diameter larger than that of the screening hole can cross the screening hole and move continuously along the screening groove is formed; each screening hole penetrates from the bottom of the screening groove to the bottom of the substrate, and a structure that needle-shaped products with the diameter smaller than the width of the screening holes can fall from the screening holes is formed.
Furthermore, the screening grooves are arranged on the upper surface of the substrate, penetrate from one side of the substrate to the other side of the substrate, one side of each screening groove is an inlet of the needle-shaped product, the other side of each screening groove is an outlet, and the screening grooves are parallel to each other; the screening holes are arranged in a row on the substrate, and the screening holes with the same width are arranged in a row and are aligned with each other.
Furthermore, the screening holes comprise screening holes with at least two widths, the screening holes with the same width are respectively arranged in a row and are aligned with each other, the screening holes are arranged according to the width, the screening holes with the small width are close to one side of an inlet of the screening groove, the screening holes with the large width are close to one side of an outlet of the screening groove, and screening is performed according to the sequence of the small diameter during screening.
Furthermore, material receiving containers are respectively arranged below the outlet of the screening groove and below the screening holes and are respectively used for receiving products with different specifications.
Furthermore, bolt holes for installation are respectively formed in two sides of the base plate, and the whole needle plate can be conveniently installed and fixed.
Preferably, the bottom of the screening slot is a slot with a semicircular cross section, so that no corner exists, which is beneficial to the movement of the screened product.
The utility model discloses change original single specification tunnel mode into the tunnel mode of two kind at least specifications on the integral type faller mould of screening usefulness, utilize the different diameters of different products, make its automatic entering predetermine the tunnel to distinguish during the different material containers that connect that discharge reaches the effect of disposable effective multiple different specification products, thereby improve screening efficiency and accuracy, can be used to the screening process of needle-like products such as various connector contact PINs, square PIN needle, circle PIN needle.

Detailed Description
In this embodiment, referring to fig. 1 to 5, the apparatus for screening needle-shaped products with different specifications by using a tunnel includes a substrate 1, a plurality of screening slots 2 capable of accommodating needle-shaped products to pass through are formed in the substrate 1, and at least one screening hole 3 is formed in each screening slot 2; the length of the screening holes 3 is smaller than that of the screening grooves 2, and the width (such as 0.64 mm) of the screening holes 3 is smaller than that of the screening grooves 2 (such as 0.77mm and the depth is 1.2 mm), so that needle-shaped products with the diameter larger than that of the screening holes 3 can pass through the screening holes 3 and continue to move along the screening grooves 2; each screening hole 3 penetrates from the bottom of the screening groove 2 to the bottom of the substrate 1, so that needle-shaped products with the diameter smaller than the width of the screening holes 3 can fall from the screening holes 3, and the screening purpose is realized.
The screening grooves 2 are arranged on the upper surface of the substrate 1, the screening grooves 2 penetrate from one side to the other side of the substrate 1 along the longitudinal direction, one side is an inlet of a needle-shaped product, the other side is an outlet, and the screening grooves 2 are parallel to each other; the screening holes 3 are aligned with each other in a row on the substrate 1.
For another embodiment, referring to fig. 6, the screening holes 3 include (at least) two kinds of screening holes, the screening holes 3 having the same width are respectively aligned in a row, the screening holes 3 are arranged according to the width, wherein the screening hole 3 having the smaller width is close to the inlet side of the screening chute 2, the screening hole having the larger width (e.g., the second screening hole 5) is close to the outlet side of the screening chute 2, and the screening is performed in the order of the smaller diameter.
Receiving containers (not shown) are respectively arranged below the outlet of the screening groove 2 and below the screening holes 3 and are respectively used for receiving products with different specifications.
The bottom of the screening groove 2 is a groove with a semicircular cross section, so that a corner is not formed, and the screened product can move conveniently.
To illustrate by taking PIN needles 6 for screening two specifications as an example, PIN needles 6 sent out through a vibrating disk enter from an inlet of a screening groove 2 and move forwards along the screening groove 2, PIN needles 6 with small diameters (such as less than 0.64 mm) fall into a material receiving container from a screening hole 3, PIN needles 6 with large diameters (such as greater than 0.64mm but less than 0.77 mm) cannot fall from the screening hole 3, but continue to move forwards along the screening groove 2, finally, the PIN needles come out from an outlet of the screening groove 3 and fall into the material receiving container, thus, the PIN needles 6 with two different specifications are screened through one needle plate, and the screening principle of the PIN needles 6 with multiple specifications is similar.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, i.e. the present invention is intended to cover all equivalent variations and modifications within the scope of the present invention.
