DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention:

[0022] In the production process related to IC carriers, the IC carriers need to be transported to the equipment by a feeding mechanism. During the production process, IC carriers of different specifications are often switched. The existing feeding mechanism cannot be quickly adjusted according to the specifications of the IC carriers. Therefore, it is considered to design the feeding trough to automatically adjust the positioning, which can be compatible with products of various specifications to achieve improved production efficiency. During the production process, the parameters can be automatically adjusted in the background software of the equipment according to the specifications of the IC carrier. The operation is simple and the positioning accuracy is high, which saves equipment control time and improves equipment utilization. As shown in the figure, the automatic feeding trough mechanism of the utility model includes a table 1. A long side reference plate 11 and a short side reference plate 12 are extended from the two adjacent sides of the table 1. The long side reference plate 11 is located on the long side of the table 1, and the short side reference plate 12 is located on the short side of the table 1. An optical fiber sensor 13 is provided on the long side reference plate 11 or the short side reference plate 12. The optical fiber sensor 13 is used to determine whether the IC carrier has reached a specified height, such as Figure 1 The optical fiber sensor 13 shown is arranged on the short side reference plate 12. The long side reference plate 11 is slidably connected to the supporting plate 4. The main body of the supporting plate 4 is located inside the long side reference plate 11 and the short side reference plate 12, and the supporting plate 4 slides in the Z direction along the long side reference plate 11 through the Z-axis mechanism 5. At the same time, the supporting plate 4 also slides in the Z direction relative to the short side reference plate 12, and the movement trajectory of the supporting plate 4 is located on the Z axis; a long side positioning structure 2 is provided opposite to the long side reference plate 11, and the long side positioning structure 2 includes a long side positioning rod 21 and a displacement sensor 24. The displacement sensor 24 monitors the displacement of the long side positioning rod 21. Here we define that the movement trajectory of the long side positioning rod 21 is located on the X axis. A short side positioning structure 3 is provided opposite to the short side reference plate 12, and the short side positioning structure 3 includes a short side positioning rod 31, a displacement sensor 24, and a displacement sensor 24 monitors the displacement of the long side positioning rod 21. Here we define that the movement trajectory of the long side positioning rod 21 is located on the X axis. Sensor 2 35, displacement sensor 2 35 determines the displacement of the short side positioning rod 31, the movement trajectory of the short side positioning rod 31 is located on the Y axis, the long side positioning rod 21 and the short side positioning rod 31 both penetrate the carrier plate 4 and slide relative to the table 1; the long side positioning rod 21 slides along the table 1 in the X direction, and the short side positioning rod 31 slides along the table 1 in the Y direction, the X direction is perpendicular to the Y direction, the long side reference plate 11, the short side reference plate 12, the long side positioning rod 21, the short side positioning rod 31 and the carrier plate 4 together form a feed trough for the IC carrier board, the movement of the long side positioning rod 21 and the short side positioning rod 31 in their respective directions adjusts the size of the feed trough to accommodate IC carrier boards of different specifications, and the movement of the carrier plate 4 lifts the IC carrier board to a specific height position.

[0023] The supporting plate 4 is provided with a short side sliding hole 41 for the short side positioning rod 31 to move back and forth. The short side sliding hole 41 is parallel to the Y axis direction. The long side sliding hole 42 is provided in the X axis direction. The long side sliding hole 42 is provided for the long side positioning rod 21 to move back and forth. Figure 1The illustrated embodiment includes three long-side positioning rods 21 and three long-side slide holes 42. The short-side slide holes 41 are perpendicular to the three long-side slide holes 42. The portion of the carrier plate 4 extending toward the long-side reference plate 11 is connected to the Z-axis mechanism 5. The long-side reference plate 11 also has corresponding Z-direction slide holes, which allow the extension of the carrier plate 4 to move up and down in the Z direction.

[0024] Specifically, such as Figure 3 As shown, the long side positioning structure 2 also includes a transmission mechanism 22, a movable plate 23, an X-direction guide rail 25 and an X-direction screw rod 26. The movable plate 23 is sleeved on the X-direction screw rod 26, and the X-direction screw rod 26 rotates under the drive of the transmission mechanism 22. The bottom ends of the three long side positioning rods 21 are connected to the movable plate 23 at intervals, and the two ends of the movable plate 23 slide along the two X-direction guide rails 25. The movement of the long side positioning structure 2 in the X direction relies on the transmission mechanism 22 to push the movable plate 23 to move. The movable plate 23 is arranged between the table 1 and the supporting plate 4 and slides in the X direction relative to the table 1. The transmission mechanism 22 is a motor and a transmission belt. The top of the long side positioning rod 21 is provided with an air blowing port 211, which is connected to the gas source through the gas diverter plate 6. The diverter plate 6 is set on the movable plate 23. The long side reference plate 11 is provided with a long side air blowing port 111, and the short side reference plate 12 is provided with a short side air blowing port 121. The long side air blowing port 111 and the short side air blowing port 121 are all connected to the diverter plate 6. The long side air blowing port 111, the short side air blowing port 121 and the air blowing port 211 can prevent the two adjacent IC carriers from sticking together. The short side positioning structure 3 is as shown in FIG. Figure 4 As shown, the short-side positioning rod 31 moves back and forth along the Y-guide rail 36 via a Y-direction screw 34 driven by a second transmission mechanism 32. The bottom end of the short-side positioning rod 31 is connected to a moving block 33, which is sleeved around the outside of the Y-direction screw 34. The end of the Y-direction screw 34, away from the second transmission mechanism 32, is sleeved within a screw bearing 341 to limit the position of the moving block 33. When the second transmission mechanism 32 is activated, the moving block 33 slides on the Y-guide rail 36. A prying structure 311 is provided at the top of the short-side positioning rod 31. The prying structure 311 is a circular bearing that rotates clockwise relative to the short-side positioning rod 31. As the circular bearing rotates, it can remove stuck IC carriers, further preventing adjacent IC carriers from sticking.

[0025] like Figure 2 As shown, the Z-axis mechanism 5 includes a Z-guide rail 51 and a connecting plate 52. One side of the connecting plate 52 is connected to an extension of the supporting plate 4, and the opposite side is connected to the Z-guide rail 51. The connecting plate 52 slides in the Z direction along the Z-guide rail 51, and the movement of the supporting plate 4 in the Z direction is realized by the connecting plate 52. The sliding of the connecting plate 52 along the Z-guide rail 51 is achieved by a stepper motor 53 and a Z-direction screw rod 54. The connecting plate 52 is sleeved on the Z-direction screw rod 54, and the output end of the stepper motor 53 drives the Z-direction screw rod 54.

[0026] The table 1 is arranged in a rotation adjustment structure 7, which adjusts the table 1 to a slight angular deviation, such as Figure 7 As shown, the rotation adjustment structure 7 includes a rotation axis 71 and a side plate 72 . The side plate 72 is connected to the short side reference plate 12 via an adjustment knob 73 . Rotating the adjustment knob 73 forces the table 1 to rotate a fine angle around the rotation axis 71 .

[0027] When in use, first rotate the adjustment knob 73 to adjust the table 1 to the correct position, and put the stacked IC carriers into the feed trough, which is surrounded by the long-side reference plate 11, the short-side reference plate 12, the long-side positioning rod 21, the short-side positioning rod 31 and the carrier plate 4; then adjust the long-side positioning structure 2, start the transmission mechanism 1 22, and the long-side positioning rod 21 moves along the X-guide rail 25 with the moving plate 23. The displacement sensor 1 24 ensures that the long-side positioning rod 21 moves into place to complete the long-side positioning; then adjust the short-side positioning structure 3, start the transmission mechanism 2 32, and the short-side positioning rod 21 moves into place to complete the long-side positioning. The positioning rod 31 moves along with the moving block 33 on the Y guide rail 36, and the displacement sensor 2 35 ensures that the short side positioning rod 31 moves into place to complete the short side positioning; finally, during the feeding process, the stepper motor 53 is started, and the carrier plate 4 moves along the Z-direction screw rod 54 along with the connecting plate 52 to lift the top material to the specified height. The optical fiber sensor 13 detects that the height is in place, and the air blowing port 211, the long side air blowing port 111, and the short side air blowing port 121 blow air towards the lower carrier plate to prevent adhesion, and the material shifting structure 311 shifts the next carrier plate down. After the feeding is completed, the carrier plate 4 returns.

[0028] The design of the utility model takes the long side reference plate 11 and the short side reference plate 12 as the reference. The long side positioning structure 2 and the short side positioning structure 3 are moved and adjusted to adapt to the different sizes of IC carriers, and the products are automatically positioned close together to ensure that the repeatability of the feeding position of the feed trough meets the requirements. In order to ensure the accuracy of the feeding height, the Z-axis automatic lifting is designed at the same time, and the Z-axis mechanism 5 is used to connect the carrier plate 4 to ensure that the feeding height error meets the requirements. The air blowing port and the material diverting mechanism designed by the mechanism can better prevent the product from sticking to the sheet and causing scrap, and effectively ensure the product quality.

[0029] The above embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
