DETAILED DESCRIPTION

[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1The material sorting device of a chip sorting machine shown in the figure includes a feeding mechanism 100 and a material sorting mechanism 200. The right end of the feeding mechanism 100 is a discharge port. The material sorting mechanism 200 is installed at the discharge port and is used to transport the chips one by one to the detection station of the sorting machine.

[0022] like Figure 3-Figure 4 As shown, the material dispensing mechanism 200 includes a base 201, which is a horizontally placed flat plate. A driving motor 202 is vertically installed on the lower side of the left end of the base 201. The driving motor 202 is a servo motor, and the output shaft of the driving motor 202 passes through the upper surface of the base 201. A linear guide 203 is installed on the upper side of the right end of the base 201, and a material collection platform 205 is installed on the linear guide 203 through a slider 204. A cam assembly 208 is fixed on the top of the output shaft of the driving motor 202, and the cam assembly 208 is connected to the material collection platform 205. The driving motor 202 rotates through the cam assembly 208 to drive the material collection platform 205 to reciprocate along the linear guide 203.

[0023] Among them, a positioning seat 206 is detachably mounted on the material taking platform 205, and the positioning seat 206 is used to position the chip. By replacing different positioning seats 206, the positioning of different types of chips can be achieved. Preferably, a detection sensor 207 is installed on the material taking platform 205, and the detection sensor 207 is a photoelectric switch, which is symmetrically mounted on both sides of the positioning seat 206 to identify whether there is a chip on the positioning seat 206.

[0024] like Figure 3-Figure 4 As shown, a lifting seat 209 is installed on the front side of the base 201, and a push rod 210 is vertically installed in the lifting seat 209 through a linear bearing. A connecting piece is fixed on the output shaft of the driving motor 202, and the connecting piece is located at the lower side of the cam assembly 208. A pressing block 211 is fixed at the lower end of the connecting piece. A first lever 212 is installed on the upper side of the base 201, and the left end of the first lever 212 is located below the connecting piece, and the right end of the first lever 212 is located below the push rod 210. When the driving motor 202 rotates to move the pressing block 211 to the upper side of the left end of the first lever 212, the pressing block 211 presses down the left end of the first lever 212, so that the right end of the first lever 212 is lifted up, and the push rod 210 is lifted up; when the driving motor 202 rotates to move the pressing block 211 away from the upper side of the left end of the first lever 212, the push rod 210 falls down under the action of gravity, so that the right end of the first lever 212 falls down and the left end is lifted up. Preferably, the lower surface of the pressing block 211 is provided with an inclined transition surface to facilitate the pressing block 211 to press the first lever 212 downward.

[0025] like Figure 1-Figure 4As shown, the base 201 is installed at the discharge port 101 of the feeding mechanism 100 through the support 213. A second lever 102 is installed on the side of the discharge port 101. The right end of the second lever 102 is fixed with a cover plate 104 through a top block 103. The top block 103 is located directly above the top rod 210. When the top rod 210 moves up, the cover plate 104 is pushed to flip open; when the top rod 210 moves down, the cover plate 104 falls back and covers under the action of gravity. Preferably, a compression spring 105 is installed below the left end of the second lever 102. The compression spring 105 is used to lift the left end of the second lever 102 to ensure the stability of the cover plate 104.

[0026] The working principle of the embodiment of the present application is as follows:

[0027] When the driving motor 202 drives the material picking platform 205 to move to the leftmost end, the pressing block 211 moves to the upper part of the left end of the first lever 212, and the pressing block 211 presses down the left end of the first lever 212, so that the right end of the first lever 212 is lifted up, and the push rod 210 is lifted up, and the cover plate 104 is opened through the push block 103, and the feeding mechanism 100 transports the chip to the positioning seat 206.

[0028] When the driving motor 202 drives the material taking platform 205 to move rightward, the pressing block 211 moves out from above the left end of the first lever 212, and the ejector 210 falls back under the action of gravity, and at the same time, the ejector block 103 descends to close the cover plate 104 to prevent the chips from continuing to flow in. This reciprocating process realizes the single chip taking out and the chip material separation action.

[0029] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0030] By installing a cam assembly and a pressure block on the output shaft of the servo motor, the cam assembly drives the material-retrieving platform to perform material-retrieving and feeding actions, and the pressure block realizes the opening and closing of the cover plate at the material outlet through the first lever and the ejector rod to prevent the entry of materials from the rear. On the one hand, the space is fully utilized and the volume of the equipment is reduced; on the other hand, the accuracy and reliability of material sorting are improved, and the efficiency of silicon wafer sorting is improved.

[0031] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0032] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0033] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
