[0026] Please see Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of this utility model proposes an automatic stamping feeding and positioning platform mechanism. This mechanism includes a stacking platform 1 arranged on one side of a positioning table 2. The positioning table 2 is equipped with a two-way transmission device for transferring flat stamped parts 100 stacked on the stacking platform 1 to the positioning table 2. As an improvement of this utility model, such as... Figure 3 , Figure 6 and Figure 7 As shown, the upper surface of the positioning platform 2 has several first guide bearing assemblies 3 arranged along its width direction on the side away from the stacking platform 1, and several second guide bearing assemblies 4 arranged along its length direction on its front side. Specifically, the rotating bushings of the first guide bearing assembly 3 and the second guide bearing assembly 4 protrude from the upper surface of the positioning platform 2, and are used to roll and align the corresponding two sides of the flat stamped part during the positioning adjustment process, so as to achieve rapid alignment and positioning of the stamped part. Figure 6 and Figure 7As shown, the upper surface of the positioning platform 2 has several parallel elongated slots 21 arranged along its width direction, with their extension direction parallel to its length direction. Each elongated slot 21 contains an elongated positioning pin 23 whose position can be adjusted synchronously. The upper surface of the positioning platform 2 also has several parallel wide slots 22 arranged along its length direction, with their extension direction parallel to its width direction. Each wide slot 22 contains a wide positioning pin 24 whose position can be adjusted synchronously. During the positioning and adjustment of the flat stamping part, the elongated positioning pins 23 can push the flat stamping part at the end furthest from the first guide bearing assembly 3, aligning the flat stamping part at the end closest to the first guide bearing assembly 3 with the first guide bearing assembly 3. When the flat stamped part has a curved or irregular side end near the first guide bearing assembly 3, the protruding side end, when in contact with the first guide bearing assembly 3, can slide between two adjacent first guide bearing assemblies 3 under the influence of the freely rotating first guide bearing assembly 3. Through dynamic alignment adjustment of the first guide bearing assembly 3, the first guide bearing assembly 3 can adaptively align the stamped part with an irregular side end. Similarly, the wide locating pin 24 can push the flat stamped part away from the second guide bearing assembly 4, aligning the flat stamped part near the second guide bearing assembly 4 with the second guide bearing assembly 4. Similarly, due to its free rotation characteristic, when the corresponding side end of the stamped part abuts against it, the protruding side end of the second guide bearing assembly 4 can slide between two adjacent second guide bearing assemblies 4, allowing the second guide bearing assembly 4 to adaptively align the stamped part with an irregular side end. Figure 1 As shown, a visual recognition robot 8 is provided on one side of the positioning platform 2. The arm of the visual recognition robot 8 is equipped with a visual recognition camera 81 for visually recognizing the size, shape, and positional deviation of the flat stamping part 100 on the positioning platform 2. The visual recognition camera 81 captures and processes images of the stamping part 100, calculates the deviation of the stamping part 100 from the ideal position, and the central controller controls the servo motor to adjust the position of the longitudinal positioning pin 23 and the lateral positioning pin 24 according to the deviation information, so that the positioning pins push the stamping part 100 to move on the positioning platform 2 until the stamping part 100 is precisely fixed in the predetermined stamping position.

[0027] Furthermore, in a preferred embodiment of this utility model, such as Figure 8 As shown, a two-way adjustment device 9 is provided on one side of the lower surface of the positioning platform 2 for controlling the displacement of the longitudinal positioning pin 23 along the length direction of the positioning platform 2 in the longitudinal strip groove 21, and for controlling the displacement of the lateral positioning pin 24 along the width direction of the positioning platform 2 in the lateral strip groove 22. Specifically, as shown... Figure 8As shown, the two-way adjustment device 9 includes a long slide rail 91 arranged along the length direction of the positioning platform 2 and a wide slide rail 92 arranged along the width direction of the positioning platform 2. A first lead screw motor 93 is provided at the end of the long slide rail 91, and a second lead screw motor 94 is provided at the end of the wide slide rail 92. Figure 8 As shown, a first fixed seat 95 is fixed on the slider of the long slide rail 91, and a second fixed seat 96 is fixed on the slider of the wide slide rail 92. The first fixed seat 95 is provided with a plurality of first buffer seats 25 for fixing the long positioning pin 23, and the second fixed seat 96 is provided with a plurality of second buffer seats 26 for fixing the wide positioning pin 24.

[0028] Furthermore, in a preferred embodiment of this utility model, such as Figure 9 As shown, the first buffer seat 25 includes a slide rail 251 fixed on a first fixed seat 95 and a slide block 252 slidably engaged with the slide rail 251, wherein a longitudinal positioning pin 23 is vertically fixed on the slide block 252. Specifically, as Figure 9 As shown, a baffle 253 is fixed to the first fixed seat 95 on the side away from the first guide bearing assembly 3. A buffer rod 254, horizontally facing the slide 252, is fixed on the baffle 253. The corresponding side of the slide 252 is provided with a rod groove for assembling the end of the buffer rod 254. A buffer spring is sleeved on the buffer rod 254, with one end fixed to the baffle 253 and the other end fixed to the slide 252. When the longitudinal positioning pin 23 pushes the side end of the stamped part, the longitudinal positioning pin 23, under the reverse thrust, moves a distance along the slide rail 251 away from the first guide bearing assembly 3 together with the slide 252. Under the action of the buffer spring on the buffer rod 254, the slide 252 has an elastic buffering effect, which can realize the elastic contact between the longitudinal positioning pin 23 and the side end of the stamped part, avoiding rigid collision between the two.

[0029] Furthermore, in a preferred embodiment of this utility model, such as Figure 6 and Figure 7 As shown, there are four equally spaced longitudinal strip grooves 21 and five equally spaced lateral strip grooves 22. Correspondingly, there are four longitudinal locating pins 23 and five lateral locating pins 22.

[0030] As a preferred embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the two-way transmission device includes a horizontal guide rail 5 bridging the stacking platform 1 and the positioning platform 2, a connecting seat 61 connected to the slide of the horizontal guide rail 5, a vertical guide rod cylinder 6 fixed to the connecting seat 61, and a matrix suction cup 7 connected to the end of the guide rod of the vertical guide rod cylinder 6. Among them, as... Figure 4 and Figure 5 As shown, the horizontal guide rail 5 is fixed to the positioning table 2 by the support 51. The upper end of the vertical guide rod cylinder 6 is provided with a guide rod fixing seat 62. The guide rod fixing seat 62 is provided with guide rods 63 located on the left and right vertical sides of the vertical guide rod cylinder 6. The lower end of the guide rod 63 passes through the connecting seat 61 via the guide rod sliding sleeve and is fixedly connected to the matrix suction cup 7. Specifically, as shown... Figure 4 As shown, the matrix suction cup 7 includes a suction cup base 71, two parallel long rods 72 fixed on the suction cup base 71, and a short rod 73 connected between the two long rods 72. The short rod 73 has suction cups 74 at both ends and in the middle. When transferring the stamped part 100, the servo motor on the horizontal guide rail 5 starts, driving the connecting seat 61 to move upwards on the stacking platform 1 via a lead screw in the horizontal guide rail 5. During this process, the vertical guide rod cylinder 6 and the matrix suction cup 7 move horizontally together with the connecting seat 61 as a whole. When the vertical guide rod cylinder 6 is above the stacking platform 1, it starts, driving its guide rod to extend downwards, thereby causing the matrix suction cup 7 to move downwards towards the stamped part 100 on the stacking platform 1. After the suction cups 74 are pressed against the surface of the stamped part 100, the suction cups 74 generate negative pressure under the control of the suction cup control cylinder, thus sucking up and fixing the stamped part 100. Subsequently, the guide rod of the vertical guide rod cylinder 6 retracts upward, causing the matrix suction cup 7 and the sucked-up stamping part 100 to move up a height. Then, the horizontal guide rail 5 returns, causing the vertical guide rod cylinder 6 to move horizontally above the positioning table 2. After bringing the stamping part 100 to the predetermined position, the guide rod of the vertical guide rod cylinder 6 extends downward, and at the same time, the suction cup 74 releases, releasing the stamping part and transferring it to the predetermined position of the positioning table 2.
