[0002] With the development of semiconductors, integration is becoming increasingly higher. In the back-end packaging and testing process, the number of wires in the wire bonding process is large, the wire diameter is thin, and the wire gap is small. When transporting the product to the packaging process, vibration can easily cause the wires to tilt or touch, resulting in defects.
[0003] Currently advanced overhead crane systems (OHT) can transport materials without vibration, but they are costly and not suitable for small and medium-sized production lines.
[0004] Currently available shockproof transport trolleys rely on shockproof wheels installed at the bottom for shock absorption. However, the springs inside the wheels can only filter out a portion of the vertical vibrations. The front, back, left, and right vibrations caused by bumps cannot be avoided, resulting in insufficient shock absorption and an inability to protect the reliability of the welding lines on the products inside the trolley.

[0007] As a further improvement of this utility model, the vehicle body is made of rods, and the upper mounting cavity is also constructed from rods.

[0026] like Figure 1 As shown, this utility model is a shockproof transport trolley used in semiconductor production, including a vehicle body 2, and a box 5 is installed on the vehicle body 2 through an elastic structure.
[0027] The upper part of the vehicle body 2 is the upper mounting cavity, in which the upper box 5 is installed via an elastic structure. The lower part of the vehicle body 2 is the lower storage compartment 8, and wheels 9 are installed at the bottom of the vehicle body 2. The vehicle body 2 is made of rods, and the upper mounting cavity is also constructed from rods.
[0028] The elastic structure consists of a lateral spring assembly and a bottom spring assembly. The lateral spring assembly includes a lateral spring 3, with the inner end of the lateral spring 3 connected to the side of the upper housing 5, and the outer end of the spring 3 connected to the inner wall of the upper mounting cavity.
[0029] In this embodiment, the upper housing 5 has a rectangular structure, and the eight corners of the upper housing 5 are respectively connected to the inner end of the spring 3 through lifting rings, and the outer end of the spring 3 is connected to the inner wall of the upper mounting cavity through lifting rings.
[0030] To adjust the elastic force, a slider is slidably installed in the inner wall of the upper mounting cavity. The slider is connected to the outer end of the spring 3 through a lifting ring and is fixed by a support bolt.
[0031] The bottom spring assembly includes a support spring 7, which abuts against the bottom of the upper housing 5 and the upper mounting cavity. To prevent the support spring 7 from detaching from the upper housing 5, a guide rod is vertically installed at the bottom of the upper housing 5, and the support spring 7 is sleeved on the outer periphery of the guide rod. To limit the lateral movement of the upper housing 5, a limiting sleeve 1 is provided at the bottom of the upper mounting cavity, and the support spring 7 is located in the limiting sleeve 1.
[0032] The upper housing 5 is made of transparent material, allowing observation of the semiconductors placed inside.
[0033] Wheel 9 is a universal wheel with braking and shock absorption functions.
[0034] like Figure 2 As shown, the upper box 5 is equipped with a box door 4.
[0035] To improve the protection of the upper housing 5, a shock-absorbing pad 6 is laid at the bottom of the upper housing 5.
[0036] The working process of this utility model is as follows:
[0037] Mobile empty trolley: The operator pushes the trolley body 2 to the product position according to their height and habits, and locks the wheels 9.
[0038] Loading products: Open the box door 4 and manually place the product into the upper box 5. Visual inspection can prevent product collisions. Close the box door 4. The product is in a shockproof protection state with the side spring assembly, bottom spring assembly, and shockproof pad 6. The closed box can prevent dust. At the same time, the lower storage compartment 8 can be used to put product turnover clamps.
[0039] Mobile load trolley: The operator releases the wheels 9 and pushes the trolley body 2. Without adjusting the direction of the transport trolley, it is pushed toward the destination. During the journey, the wheels 9 filter the vertical vibrations generated by the ground, and the lateral spring assembly and the bottom spring assembly filter the remaining vertical vibrations and the vibrations in the front, back and sides.
[0040] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
