Description

Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to an anti-dumping device for a Burn-In aging test board operating vehicle. Background Art

[0002] During the semiconductor packaging and testing phase, chips undergo burn-in testing to detect premature product failures. Because finished ICs are carried on trays, while BI testing uses a burn-in test board, BI testing requires a loading and unloading machine to transfer the product from the tray to the burn-in test board. A burn-in test board carriage then transports the burn-in test board from the loading and unloading machine to the BI burn-in tester, ultimately placing the burn-in test board in the BI oven for testing.

[0003] However, the main body of the existing Burn-In test board transportation trolley is high and narrow, and there is a risk of tipping over during transportation. In actual production, tipping over has occurred, and after the trolley tipped over, it would cause damage to the transported BI test board and the products on the test board. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides an anti-dumping device for a Burn-In aging test board operating vehicle.

[0005] To achieve the above objectives, an anti-dumping device for a Burn-In aging test panel transport vehicle is designed, comprising a vehicle body. The structure of the vehicle body is a rectangular frame structure, forming an accommodating cavity. Limiting plates are respectively provided on both sides of the accommodating cavity, and the four corners of the bottom of the vehicle body are respectively connected to roller one. The bottom end of one side of the vehicle body is connected to an anti-dumping bar, one end of the anti-dumping bar is connected to the rectangular frame structure of the vehicle body, and the lower side of the other end of the anti-dumping bar is connected to roller two.

[0006] The height of the second roller is the same as that of the first roller.

[0007] The vehicle body is a double-layer rectangular frame structure.

[0008] An anti-collision device is provided on one side of the vehicle body, which includes an anti-collision plate, connecting plate 1, and connecting plate 2. One end of the vehicle body is connected to connecting plate 1, and connecting plate 2 is provided on the outside of connecting plate 1. A gap is formed between connecting plate 1 and connecting plate 2, and an anti-collision plate is provided in the gap.

[0009] The anti-collision plate is provided with a waist-shaped hole, and bolts pass through the waist-shaped hole to fix the anti-collision plate to the first connecting plate and the second connecting plate.

[0010] The connecting plate 1 and the connecting plate 2 are connected via a connecting block. There are two connecting blocks, which are respectively located on both sides of the anti-collision plate.

[0011] One end of the anti-collision plate is provided with a handle.

[0012] Compared with the prior art, the utility model improves the stability of the trolley and effectively prevents the trolley from tipping over. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings. Example 1

[0020] like Figure 1 As shown, the structure of the vehicle body 1 is a rectangular frame structure, forming a accommodating cavity 2, with limit plates 3 on both sides of the accommodating cavity 2, and rollers 4 are connected to the four corners of the bottom of the vehicle body 1. The bottom end of one side of the vehicle body 1 is connected to an anti-dumping strip 5, one end of the anti-dumping strip 5 is connected to the rectangular frame structure of the vehicle body 1, and the lower side of the other end of the anti-dumping strip 5 is connected to roller 2 6.

[0021] The height of roller 2 6 is the same as that of roller 1 4 to prevent the instability of the trolley caused by the height difference.

[0022] The vehicle body 1 is a double-layer rectangular frame structure.

[0023] When the present invention is in use, the burn-in test board is placed in the accommodating cavity 2 of the vehicle body. The stopper plate 3 acts as a limiter to prevent the burn-in test board from falling during operation. The anti-tipping bar 5 forms a triangular structure with the two corners of the rectangular frame structure, utilizing the stability of the triangle to enhance the stability of the vehicle. Example 2

[0024] This embodiment only describes the differences from the first embodiment, and the similarities are not described again.

[0025] The difference between this embodiment and the first embodiment is that Figures 2 to 6 As shown, an anti-collision device 7 is provided on one side of the vehicle body 1, and the anti-collision device includes an anti-collision plate 7-3, a connecting plate 1 7-1, and a connecting plate 2 7-2. One end of the vehicle body 1 is connected to the connecting plate 1 7-1, and a connecting plate 2 7-2 is provided on the outer side of the connecting plate 1 7-1. A gap is formed between the connecting plate 1 7-1 and the connecting plate 2 7-2, and an anti-collision plate 7-3 is provided in the gap.

[0026] The anti-collision plate 7-3 is provided with a waist-shaped hole 7-4, and a bolt passes through the waist-shaped hole 7-4 to fix the anti-collision plate 7-3 to the connecting plate 1 7-1 and the connecting plate 2 7-2. When used, the length of the anti-collision plate 7-3 can be adjusted by the waist-shaped hole 7-4 and the bolt.

[0027] The connecting plate 1 7-1 and the connecting plate 2 7-2 are connected by a connecting block 7-5. There are two connecting blocks 7-5, which are respectively located on both sides of the anti-collision plate 7-3.

[0028] One end of the anti-collision plate 7-3 is provided with a handle 7-6, which is convenient for pulling out the anti-collision plate 7-3.

[0029] This embodiment adds an anti-collision device on the basis of the first embodiment. When in use, the anti-collision plate 7-3 is pulled out through the handle 7-6, and the anti-collision plate 7-3 blocks the outside of the Burn-In test plate, thereby protecting and preventing the Burn-In test plate.
