[0024] according to Figure 1 to Figure 8 The utility model discloses a device for automatically pushing and separating tweezers, comprising a conveying mechanism 1 and a single pushing mechanism 2. The single pushing mechanism 2 comprises a frame 3, a blanking plate 4, a sliding frame, a limiting layer plate group, and a pushing mechanism capable of moving the sliding frame back and forth.

[0025] The limiting layer plate group includes 3-8 fixed layer plates 5, preferably 5 fixed layer plates 5, both sides of the fixed layer plates 5 are fixed on the frame 3, the 3-8 fixed layer plates 5 are vertically offset and arranged in parallel from top to bottom, a sliding gap is provided between each two adjacent fixed layer plates 5, the top of the plane where each fixed layer plate 5 is located is inclined toward the discharge port 6 of the frame 3, and the discharge port 6 is located on one side of the upper end of the limiting layer plate group. The lower end of the unloading plate 4 is located on one side of the lower end of the limiting layer plate group, and the sliding gap is provided between the unloading plate 4 and the lower end of the limiting layer plate group, and the upper end of the unloading plate 4 is connected to the conveying mechanism 1.

[0026] The sliding frame 7 is located below the limiting layer plate group, and the side of the sliding frame 7 close to the limiting layer plate group is stepped, and a sliding plate 8 is fixed on one side of each step. The number of the sliding plates 8 is equal to the number of the fixed layer plates 5, and the sliding plates 8 are located in the sliding gap, that is, the fixed layer plates 5 and the sliding plates 8 are arranged laterally at intervals; the sliding plate 8 can move back and forth up and down along the sliding gap, and the stroke of the top surface of the sliding plate 8 moves back and forth between the tops of two adjacent fixed layer plates 5; the widths of the top surfaces of the fixed layer plates 5 and the top surfaces of the sliding plate 8 match the width of a single material being pushed, so that when the sliding plate 8 is pushed up, the top surface of the sliding plate 8 just lifts up one piece of material being pushed.

[0027] The top surface of the fixed layer plate 5 and the top surface of the sliding plate 8 are inclined downward toward the discharge port 6, respectively, so that the material can more easily fall from the top surface of the sliding plate 8 to the top surface of the fixed layer plate 5, or the material can more easily fall from the top surface of the fixed layer plate 5 to the top surface of the sliding plate 8. The plane where the unloading plate 4 is located is at an angle of 45 to 90 degrees with the plane where the fixed layer plate 5 is located, preferably 70 degrees. The top surface width of the fixed layer plate 5 is 4 to 20 mm, preferably 10 mm, and the top surface width of the sliding plate is 4 to 20 mm.

[0028] The sliding frame 7 is connected to the pushing mechanism. The pushing mechanism includes a cylinder 9, a slider 10 and a slide rail 11, the slide rail 11 is fixed on the frame 3, the slider 10 is slidably connected to the slide rail 11, one side of the slider 11 is connected to the sliding frame 7, the output end of the cylinder 9 is connected to the sliding frame 7 or the slider 11, the cylinder 9 drives the sliding frame 7 to move back and forth, and makes the sliding plate 8 move back and forth in the sliding gap.

[0029] When the cylinder 9 pushes the sliding frame 7 upward to move into position, the sliding plate 8 closest to the discharge port 6 overlaps laterally with the fixed layer plate 5 closest to the discharge port 6, and the top surface of the sliding plate 8 is aligned with the top surface of the fixed layer plate 5 or the top surface of the fixed layer plate 5 is slightly lower than the top surface of the sliding plate 8.

[0030] When the cylinder 9 drives the sliding frame 7 to move downward into position, the sliding plate 8 closest to the discharge port 6 overlaps laterally with the second fixed layer plate 5 below the discharge port 6, and the top surface of the sliding plate 8 is aligned with the top surface of the second fixed layer plate 5 or the top surface of the sliding plate 8 is slightly lower than the top surface of the second fixed layer plate 5. At this time, the top surface of the sliding plate 8 close to the lower end of the blanking plate 4 is flush with the lower end of the blanking plate 4.

[0031] A first sensor 12 is provided at the lower end of the lower edge of the blanking plate 4, and the first sensor 12 is used to detect whether there is material at the lower end of the blanking plate 4; when it is detected that there is material at the lower end of the blanking plate 4, the conveying mechanism 1 stops unloading, and when there is no material at the lower end of the blanking plate 4, the conveying mechanism 1 pushes the material into the blanking plate 4, and the material slides from the upper end of the blanking plate 4 to the lower end of the blanking plate 4. A second sensor 13 is provided on the discharge port 6, and the second sensor 13 is used to detect whether there is material at the discharge port 6.

[0032] The conveying mechanism 1 is preferably a conveyor belt mechanism. The signal transmission control of the first sensor 12 and the second sensor 13 and the driving principle of the cylinder 9 in the present invention are existing technologies in the field of numerical control equipment, and the present invention will not elaborate on them.

[0033] according to Figure 4-Figure 7When the utility model is used, the initial position of the sliding plate 8 is the same as the position when the cylinder 9 drives the sliding frame 7 to move downward into position. The conveying mechanism 1 transfers the materials 14 to be sorted to the unloading plate 4 one by one, and the first sensor 12 is used to detect whether there is material at the lower end of the unloading plate 4; when it is detected that there is material 14 at the lower end of the unloading plate 4, the conveying mechanism 1 stops unloading; when there is no material 14 at the lower end of the unloading plate 4, the conveying mechanism 1 unloads, and the material 14 slides along the unloading plate 4 into the lower end of the unloading plate 4 and falls on the top surface of the sliding plate 8 adjacent to the lower end of the unloading plate 4. The cylinder 9 pushes the sliding frame 7 to move obliquely upward, such as Figure 5 , the oblique upper direction is the direction of arrow a, driving the sliding plate 8 to move obliquely upward, thereby pushing the material on the top surface of the sliding plate 8 to move obliquely upward along the fixed layer plate 5 until the sliding plate 8 is pushed into place, such as Figure 6 , the top surface of the sliding plate 8 is located on one side of the top surface of the fixed layer plate 5. Since the top surfaces of the sliding plate 8 and the fixed layer plate 5 are both inclined, the material 14 slides from the top surface of the sliding plate 8 to the top surface of the fixed layer plate 5 along the direction of arrow b, thereby completing a push, that is, the material 14 rises one step; then the cylinder 9 drives the 7 to move downward into position, as shown in FIG. Figure 7 , the sliding plate 8 is reset, and then the above-mentioned pushing process is repeated. When the single material 14 reaches the discharge port 6, the right clamping mechanism, usually a mechanical arm, clamps the tweezers of the discharge port 6 away for packaging.

[0034] according to Figure 8 The limiting layer plate group includes 3-8 fixed layer plates 5, preferably 5 fixed layer plates 5. The purpose of setting multiple fixed layer plates 5 is: in the actual process of sorting materials 14, since the materials 14 usually have irregular structures, such as tweezers, when the tweezers are in the initial state, the two clamping arms are close together to form a rod shape, but the head end is still bent, and it is easy for two or more tweezers to stick together during the pushing process. Therefore, in order to ensure that the tweezers are in a single state when they finally reach the discharge port 6, multiple fixed layer plates 5 and sliding plates 8 are set to achieve multi-stage pushing. During the repeated upward pushing of the sliding plate 8, the top surfaces of the fixed layer plates 5 and the sliding plate 8 can only accommodate tweezers of one width, and the displacement of the material and the pushing vibration caused by pushing, the excess tweezers that are stuck will fall directly to the lower end of the unloading plate 4, so that when the tweezers reach the discharge port 6, the sorting work of a single tweezer can be completed, thereby improving the accuracy and sorting efficiency.
