Technical Field
[0001] The utility model relates to the field of chip manufacturing technology equipment, in particular to a limiting structure for a semiconductor chip transportation device. Background Art
[0002] During the chip manufacturing process, the chips need to be divided into materials. When using a dividing tray for dividing the chips, a pushing machine is required to push the chips to the feed port of the dividing tray, and then the dividing tray will divide the chips. In this way, if the dividing tray does not catch the chips during the process of being pushed up, the chips will be pushed to the outside of the dividing tray, affecting the transportation of the chips and the transportation efficiency of the chips.
[0003] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention
[0004] In order to solve the above problems, the utility model discloses a limiting structure for a semiconductor chip transportation device, which can prevent the chip from being lifted up to the outside of the material distribution tray and unable to be transported by the material distribution tray, and can facilitate observation of the chip and convenient removal when the chip is stuck.
[0005] The technical solution of the utility model is: a limiting structure for a semiconductor chip transportation device, comprising a fixed block, a connecting plate, an elastic plate, an L-shaped plate and a limiting block located on one side of a material distribution tray, the fixed block is located on one side of a chip feed port of the material distribution tray, the fixed block is connected to a connecting plate, a notch is provided at the lower part of the connecting plate, an L-shaped plate is provided at the upper part of the connecting plate, an elastic plate is connected between the L-shaped plate and the fixed block, a limiting block is provided on the L-shaped plate, and a groove body is provided at the bottom of the limiting block.
[0006] By adopting the above technical solution, when the dividing tray is dividing the chips, the machine at the bottom of the dividing tray will lift the chips upwards. At this time, the limit blocks of the limit structure will just abut the chips to prevent the chips from going upwards and exceeding the position of the dividing tray.
[0007] Preferably, the extension plate at the bottom of the fixed block is fixed to the rear side of the feed distribution tray by bolts, one end of the connecting plate is rotatably connected to the side of the fixed block by a rotating shaft, and the other end of the connecting plate is located on the side above the feed port.
[0008] By adopting the above technical solution, the fixed block is fixed behind the material distribution plate, which makes it convenient for the connecting plate to drive the limit block to abut against the chip, so that the fixed block exerts a certain force on the limit block.
[0009] Preferably, the inward notch at the bottom of the connecting plate is on the side close to the feed port, and the position of the notch can be just stuck above the distribution plate. An inward limiting plate is provided on the side of the end of the connecting plate above the notch.
[0010] By adopting the above technical solution, the notch is located just above the dividing plate, and the connecting plate is located just above the feed port of the dividing plate, so that the limit block is located just above the feed port. When the chip is lifted upward, the limit block plays a limiting role to prevent the chip from going upward and exceeding the dividing plate.
[0011] Preferably, the L-shaped plate is buckled on the upper part of the connecting plate and fixed by long-head bolts, and the bottom of the part of the L-shaped plate located inside the connecting plate is located above the notch and above the edge of the notch.
[0012] Preferably, the limiting block is located inside the limiting plate of the connecting plate, and the bottom of the limiting block is located at the position of the notch in the horizontal plane, that is, the bottom of the limiting block is located below the bottom of the connecting plate.
[0013] By adopting the above technical solution, the connecting plate is located above the dividing tray. Since the feed port of the dividing tray is located inside the dividing tray and the chip is located below the feed port, the notch of the connecting plate is located just above the dividing tray. The limit block is located just above the chip at the feed port of the dividing tray, which abuts the chip and prevents it from exceeding the dividing tray.
[0014] Preferably, the upper surface of the fixing block is located above the bottom of the L-shaped plate, one end of the elastic plate is located on the upper surface of the fixing block, and the other end is located at the bottom of the inverted L-shaped plate.
[0015] By adopting the above technical solution, the elastic plate plays a certain elastic role. When the chip is facing upward, the limit block has a downward force on the chip. Since the chip is relatively fragile, the elastic plate can make the limit block upward when the limit block contacts the chip to prevent the limit block from causing damage to the chip.
[0016] Preferably, the groove body includes a limit plate a and a limit plate b, the limit plate a and the limit plate b are perpendicular to the side of the limit block, the limit plate a and the limit plate b are parallel to the connecting plate, and a gap is provided between the limit plate a and the limit plate b, and the distance between the limit plate a and the limit plate b is smaller than the chip.
[0017] By adopting the above technical solution, the limiting plates a and b of the slot body just abut against the chip, and the interval inside the slot body makes it easy for the staff to observe it. If the chip is stuck inside, it is also convenient to remove the chip from the slot body.
[0018] Preferably, the limiting block and the groove body are located just above the chip feed port, so as to limit the chip.
[0019] By adopting the above technical solution, when the chip is lifted upward, the limiting block just plays a role of abutment.
[0020] Advantages of the present invention: 1. The present invention provides an elastic plate between the L-shaped plate and the fixed block. When the limit block contacts the chip, the elastic plate has a certain buffering effect on the limit block, thereby preventing the limit block from damaging the chip.
[0021] 2. The utility model uses the groove body on the side of the limit block to abut the chip. The interval between the limit plate a and the limit plate b in the groove body can facilitate observation of the chip. If the chip is stuck in the groove body, it is also convenient to remove the chip.
[0022] 3. The utility model can improve the material distribution speed of the material distribution plate to the chip, prevent the chip from being pushed to the outside of the material distribution plate, and can reduce the chip breakage rate, making it convenient to remove the chip.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0029] like Figure 1-4 As shown, a limiting structure for a semiconductor chip transportation device comprises a fixed block 2, a connecting plate 3, an elastic plate 6, an L-shaped plate 7 and a limiting block 8 located on one side of a dividing tray 1. The fixed block 2 is located on one side of a chip feed port 1-1 of the dividing tray 1. The fixed block 2 is connected to a connecting plate 3. A notch 3-1 is provided at the lower portion of the connecting plate 3. An L-shaped plate 7 is provided at the upper portion of the connecting plate 3. An elastic plate 6 is connected between the L-shaped plate 7 and the fixed block 2. A limiting block 8 is provided on the L-shaped plate 7. A groove body 9 is provided at the bottom of the limiting block 8. When the dividing tray 1 is dividing chips, the machine at the bottom of the dividing tray 1 lifts the chip upward. At this time, the limiting block 8 of the limiting structure just abuts against the chip to prevent the chip from moving upward and exceeding the position of the dividing tray 1.
[0030] The extension plate 2-1 at the bottom of the fixed block 2 is fixed to the rear side of the feed of the distribution tray 1 by bolts. One end of the connecting plate 3 is rotatably connected to the side of the fixed block 2 through the rotating shaft 4. The other end of the connecting plate 3 is located on the side above the feed port 1-1. The fixed block 8 is fixed to the rear of the distribution tray 1, which facilitates the connecting plate 3 to drive the limit block 8 to abut the chip, so that the fixed block 2 exerts a certain force on the limit block 8.
[0031] The inward notch 3-1 at the bottom of the connecting plate 3 is close to the side of the feed port 1-1, and the position of the notch 3-1 can be stuck just above the dividing plate 1. An inward limiting plate 5 is provided on the side of the end of the connecting plate 3 above the notch 3-1. The notch 3-1 is just above the dividing plate 1, and the connecting plate 3 is just above the feed port 1-1 of the dividing plate 1, so that the limiting block 8 is just above the feed port 1-1. When the chip is pushed upward, the limiting block 8 plays a limiting role to prevent the chip from being pushed upward and exceeding the dividing plate 1.
[0032] The L-shaped plate 7 is buckled on the upper part of the connecting plate 3 and fixed by long-head bolts. The bottom of the L-shaped plate 7 located on the inner side of the connecting plate 3 is located above the notch 3-1 and on the upper edge of the notch 3-1. The limit block 8 is located on the inner side of the limit plate 5 of the connecting plate 3. The bottom of the limit block 8 is located at the position of the notch 3-1 in the horizontal plane, that is, the bottom of the limit block 8 is located below the bottom of the connecting plate 3. The connecting plate 3 is located above the dividing plate 1. Since the feed port 1-1 of the dividing plate 1 is located in the dividing plate 1 and the chip is located below the feed port 1-1, the notch 3-1 of the connecting plate 3 is just above the dividing plate 1, and the limit block 8 is just located above the chip at the feed port 1-1 of the dividing plate 1, which abuts the chip to prevent it from moving upward and exceeding the dividing plate.
[0033] The upper surface of the fixed block 2 is located above the bottom of the L-shaped plate 7, one end of the elastic plate 6 is located on the upper surface of the fixed block 2, and the other end is located at the bottom of the inverted L-shaped plate 7. The elastic plate 6 plays a certain elastic role. When the chip is facing upward, the limit block 8 has a downward force on the chip. Since the chip is relatively fragile, the elastic plate 6 can make the limit block 8 upward when the limit block 8 contacts the chip to prevent the limit block 8 from causing damage to the chip.
[0034] The trough body 9 includes a limit plate a9-1 and a limit plate b9-2, the limit plate a9-1 and the limit plate b9-2 are perpendicular to the side of the limit block 8, the limit plate a9-1 and the limit plate b9-2 are parallel to the connecting plate 3, and a gap is provided between the limit plate a9-1 and the limit plate b9-2, and the distance between the limit plate a9-1 and the limit plate b9-2 is smaller than the chip, the limit plate a9-1 and the limit plate b9-2 of the trough body 9 just abut against the chip, and the gap inside the trough body 9 can facilitate the staff to observe it, and if the chip is stuck inside, it is also convenient to remove the chip in the trough body 9.
[0035] The limit block 8 and the groove body 9 are located just above the chip feed port 1-1, and play a role in limiting the chip. When the chip is pushed upward, the limit block 8 plays a role in abutment.
[0036] When the chip at the lower part of the feed port 1-1 of the dividing tray 1 is lifted up by the machine, the feed port 1-1 located above the chip just acts as abutment against the chip to prevent the chip in the feed port 1-1 from moving upward and exceeding the dividing tray. At the same time, the elastic plate 6 can buffer the chip to prevent damage to the chip.
