Description

Technical Field

[0001] The utility model relates to the technical field of electronic component manufacturing, and particularly relates to a storage tray. Background Technique

[0002] A chip is an important component inside an electronic device, which can improve performance, reduce costs, and simplify circuit design. The chip has functions such as data processing, information storage, signal control, and data conversion. The connection method of some chips is to be soldered to a printed circuit board through pins. During processing, a storage tray is needed for storage or transportation. The current storage trays usually have grooves matching the shape of the chip to place components. During production, the vacuum suction method is usually used to pick up the chip, and the chip needs to be pressed and adsorbed. During the pressing process, the pins at the lower end or side of the chip collide and squeeze with the bottom or side wall of the groove in the tray, which is likely to cause bending and damage to the chip. Therefore, a storage tray is proposed to solve the above problems. Content of the Utility Model

[0003] To solve the above technical problems, a storage tray is provided. This technical solution solves the problem that the pins of the chip are easily squeezed and damaged when the storage tray places the chip and picks it up by vacuum suction.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A storage tray includes a tray body. A plurality of storage grooves are arranged above the tray body, and the plurality of storage grooves are arranged in an array. An element support plate is fixedly connected to the bottom of the storage groove. Air bags are arranged on both sides of the element support plate. A pressurizing device is arranged on the right side of the tray body.

[0006] The pressurizing device includes a pressurizing pipe, a piston rod, a sliding block, and a chute. The pressurizing pipe is sleeved outside the piston rod. One end of the piston rod located inside the pressurizing pipe is connected to a piston. The piston is slidably connected to the inner wall of the pressurizing pipe. The other end of the piston rod is fixedly connected to the sliding block. Both ends of the sliding block are slidably connected to the inner wall of the chute.

[0007] Preferably, clamping blocks are arranged at the grooved parts of both inner walls of the chute. One end of the clamping block is rotatably connected to the side wall of the chute through a rotating shaft. A pressing block is arranged above the clamping block. The periphery of the pressing block is slidably connected to the chute. A wedge-shaped through hole is opened in the middle of the clamping block.

[0008] Preferably, the bottom of the pressing block is slidably connected to the side wall of the wedge-shaped through hole. A spring is arranged between the clamping block and the side wall of the chute.

[0009] Preferably, a plurality of air pipes are provided at the bottom of the tray body. The air pipes are arranged on both sides of the storage groove and communicated with each airbag, and the other ends of the air pipes are communicated with the inside of the pressure pipe.

[0010] Preferably, a bottom groove is formed at the bottom of the frame of the tray body, and the bottom groove is arranged as a trapezoidal groove.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows:

[0012] 1. In this solution, a storage groove is provided. An element support plate is arranged inside the storage groove. The chip is placed on the element support plate, and the pins on both sides are located between the element support plate and the storage groove. The airbags on both sides of the storage groove bulge after being inflated to squeeze and fix the chip pins. The material of the airbag is relatively soft and will not exert too much pressure on the pins. When the chip is taken by means of vacuum suction, the airbags on both sides play a supporting role for the chip. The chip will not change its position due to vibration on the element support plate, and at the same time, downward extrusion will not exert pressure on the chip pins, avoiding bending of the chip pins due to stress. Fixing the chip by the airbag is also more stable during transportation, avoiding chip detachment.

[0013] 2. By providing a pressurizing device to inflate and pressurize the airbag, after pressurization, the spring pushes the block so that the block is stuck on one side of the sliding block to limit and fix the sliding block, sealing the gas inside the pressure pipe, the air pipe and the airbag, so that the airbag continuously bulges to fix the chip.

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0024] As Figure 1-2 shown, a storage tray includes a tray body 1. Above the tray body 1, a plurality of storage grooves 2 are provided. The plurality of storage grooves 2 are arranged in an array. A component support plate 21 is fixedly connected to the bottom of the storage groove 2. Air bags 22 are provided on both sides of the component support plate 21. The component support plate 21 is smaller than the storage groove 2. The chip is placed above the component support plate 21, and the pins on both sides are located between the component support plate 21 and the storage groove 2. A pressurizing device 3 is provided on the right side of the tray body 1.

[0025] As Figure 3 shown, a plurality of air pipes 23 are provided at the bottom of the tray body 1. The air pipes 23 are arranged on both sides of the storage groove 2 and communicate with each air bag 22. By supplying air and pressurizing each air bag 22 through the air pipes 23, the air bags 22 can bulge to squeeze the pins on both sides of the chip to fix the chip. The material of the air bags 22 is relatively soft and will not exert too much pressure on the pins. When the chip is taken by vacuum suction, the air bags 22 on both sides play a supporting role for the chip. The chip will not move due to vibration on the component support plate 21, and downward extrusion will not exert pressure on the chip pins, avoiding bending of the chip pins due to force. A bottom groove 11 is formed at the bottom of the frame of the tray body 1. The bottom groove 11 is a trapezoidal groove. Through the bottom groove 11, the tray bodies 1 can be stacked and placed.

[0026] Please refer to Figure 4-5, the pressurizing device 3 includes a pressurizing pipe 31, a piston rod 32, a sliding block 33 and a chute 34. The pressurizing pipe 31 is sleeved outside the piston rod 32. One end of the piston rod 32 inside the pressurizing pipe 31 is connected with a piston. The piston is slidably connected with the inner wall of the pressurizing pipe 31. The other end of the piston rod 32 is fixedly connected with the sliding block 33. Both ends of the sliding block 33 are slidably connected with the inner wall of the chute 34. Clamping blocks 35 are arranged at the grooved parts on both inner walls of the chute 34. One end of the clamping block 35 is rotatably connected with the side wall of the chute 34 through a rotating shaft. A pressing block 36 is arranged above the clamping block 35. The periphery of the pressing block 36 is slidably connected with the chute 34. A wedge-shaped through hole 37 is formed in the middle of the clamping block 35. The bottom of the pressing block 36 is slidably connected with the side wall of the wedge-shaped through hole 37. A spring 38 is arranged between the clamping block 35 and the side wall of the chute 34. The pressurizing pipe 31 is communicated with the air pipe 23. By squeezing the piston rod 32 into the pressurizing pipe 31, the air bag 22 can be pressurized through the air pipe 23. After pushing the sliding block 33 to make the sliding block 33 pass through the clamping block 35, the spring 38 pushes the clamping block 35 to make the clamping block 35 clamp on one side of the sliding block 33 to limit and fix the sliding block 33, and seal the gas inside the pressurizing pipe 31, the air pipe 23 and the air bag 22. When it is necessary to decompress the air bag 22, press the pressing block 36. The pressing block 36 slides downward to squeeze the side wall of the wedge-shaped through hole 37, so that the clamping block 35 rotates towards the inside of the side wall of the chute 34 along the rotating shaft, and the sliding block 33 is released. The air pressure inside the pressurizing pipe 31 pushes out the piston rod 32.

[0027] The principle of the present utility model is as follows: When using this storage tray, the chip is placed above the component support plate 21, and the chip pins are located between the component support plate 21 and the storage groove 2. Push the sliding block 33 to make the piston rod 32 push the piston to squeeze the air inside the pressurizing pipe 31, and inflate and pressurize the air bag 22 through the air pipe 23, so that the air bag 22 bulges to squeeze the chip pins to fix the chip. When the chip is taken by the way of vacuum suction, the air bags 22 on both sides play a supporting role for the chip. The chip will not change its position due to vibration on the component support plate 21, and downward extrusion will not generate pressure on the chip pins, avoiding the bending of the chip pins due to force. Clamping blocks 35 are arranged on both sides of the chute 34 to limit and fix the sliding block 33, so that the air bag 22 continuously bulges to provide support for the chip. When it is necessary to release the sliding block 33, just press the pressing block 36. The pressing block 36 slides downward to squeeze the side wall of the wedge-shaped through hole 37, so that the clamping block 35 rotates towards the inside of the side wall of the chute 34 along the rotating shaft, and the sliding block 33 is released. The air pressure inside the pressurizing pipe 31 pushes out the piston rod 32, and the air bag 22 is decompressed. By arranging the air bag 22 to squeeze and fix the chip pins, the air bag 22 has a soft texture and will not generate too much pressure on the pins, avoiding damage to the chip.
