And because the positive pin and the negative pin of the capacitor are different in length, after the capacitor is processed by the translation feeding mechanism in the application, the capacitor is output in a uniform posture, for example, all capacitors are output in a mode that the long pin is on the left side and the short pin is on the right side, so that the subsequent mechanical processing is facilitated.

Fig. 2 is a schematic arrangement diagram of the units in a top view of the translational feeding mechanism in an embodiment of the present application. As shown in fig. 1 and 2, the translation feeding mechanism includes a product conveying unit 100, a flattening unit 300, a detecting unit 400, a steering unit 500, an output unit 600, and a carrying unit 200. Wherein the product conveying unit 100 is used for conveying products, as shown in fig. 2, the products are capacitors 10, and the capacitors 10 are conveyed in a line in the product conveying unit 100. The flattening unit 300 is used to press the leads of the product to flatten the leads, for example, when the leads are bent, the leads can be straightened by the pressing of the flattening unit 300, and as another example, when two leads are overlapped together, the two leads can be separated by the flattening unit 300. The detecting unit 400 is used to detect the length of the leads, for example, when the product output mode is set to output with the long leads on the left side and the short leads on the right side, if the detecting unit 400 detects that the leads of the products are not consistent with the above, the product is horizontally rotated by 180 ° by the turning unit 500, or if the leads of the products detected by the detecting unit 400 are consistent with the above, the turning unit is not operated by the turning unit between the products. The conveying unit 200 is used for conveying the product from the product conveying unit 100 to the flattening unit 300 for flattening the leads, for conveying the flattened leads from the flattening unit 300 to the detection unit 400 for detecting the length of the leads, for conveying the product from the detection unit 400 to the turning unit 500 for adjusting the posture of the product, and for conveying the product from the turning unit 500 to the output unit 600.

As shown in fig. 2, the capacitors 10 pass through the translation feeding mechanism from left to right in sequence. In one embodiment, the product conveying unit 100, the flattening unit 300, the detecting unit 400, the steering unit 500, and the output unit 600 are sequentially arranged from left to right, and the carrying unit 200 includes the clamping fingers 210, and the clamping fingers 210 can be synchronously moved along the X-axis direction, and the clamping fingers 210 can be designed to be independently moved along the Y-axis direction as needed. Specifically, the carrying unit 200 includes a gripping finger 210A, a gripping finger 210B, a gripping finger 210C, and a gripping finger 210D, respectively, from left to right along the X-axis direction. The carrying unit 200 has two working positions, a first working position and a second working position, along the X-axis direction. When the carrying unit 200 is located at the first working position, i.e. the state shown in fig. 2, the clamping finger 210A corresponds to the output end 110 of the conveying unit, the clamping finger 210B corresponds to the leveling unit 300, the clamping finger 210C corresponds to the detecting unit 400, and the clamping finger 210D corresponds to the turning unit 500. When the conveying unit 200 is located at the second working position, that is, after the four fingers 210A, 210B, 210C, 210D move rightwards synchronously, the finger 210A just corresponds to the leveling unit 300, and at this time, the finger 210A conveys the product from the product conveying unit 100 to the leveling unit 300; the clamping fingers 210B just correspond to the detecting unit 400, and at this time, the clamping fingers 210B carry the product from the flattening unit 300 to the detecting unit 400; the gripping fingers 210C just correspond to the turning unit 500, and at this time, the gripping fingers 210C carry the product from the flattening unit 300 to the turning unit 500; the gripping finger 210D exactly corresponds to the output unit 600, i.e. the gripping finger 210D carries the product from the turning unit 500 to the output unit 600. The leveling device can then repeat the above process to achieve rapid leveling of the product.

Since the four fingers 210A, 210B, 210C, 210D move along the X-axis direction synchronously, the leveling process is fast, and the conveying efficiency is high, so that the conveying accuracy of the conveying unit 200 is highly required. In order to ensure a stable product handling process and thus a reliable product flattening, in one embodiment, a structure of the handling unit 200 is provided, for example, as shown in fig. 1 and 2, the handling unit 200 may further include a translation assembly 220 and a driving assembly 230. The translation assembly 220 is used for driving the clamping finger 210 to move between different stations along the X-axis direction, so as to ensure that the clamping finger 210 is stable in movement direction and can still move in an accurate direction during rapid movement; the driving assembly 230 is used for driving the translation assembly 220 to move, and can ensure that the clamping fingers 210 accurately move to the first working position and the second working position during rapid movement, so that the carrying precision of products is ensured.

The swinging end 2312 may be provided with a sliding slot 2314, the sliding slot 2314 may be a long strip or a U-shaped slot, and one end of the translation assembly 220 is slidably connected in the sliding slot 2314, so that the translation assembly 220 is driven to translate through a side wall of the sliding slot 2314.

As shown in fig. 3, in one embodiment, the drive assembly 230 may further include a limit assembly 240; the limiting component 240 is used for limiting the moving range of the swinging end 2312, i.e. for limiting the rotating angle of the swinging rod 231, so that the swinging rod 231 rotates within a fixed angle range, and the clamping finger 210 alternately runs between the first working position and the second working position.

In one embodiment, the striking plate 252 may be provided with a screw, i.e., the moving range of the swinging end 2312 can be changed by adjusting the length of the head of the screw protruding out of the striking plate 252 or the fixing plate 251, so as to change the first working position and the second working position of the clamping finger 210. Therefore, the first working position and the second working position of the clamping fingers 210 can be accurately determined by adjusting the limit pins 254, and the conveying precision of the conveying unit 200 is improved.
