Description

Technical Field

[0001] This utility model relates to the field of semiconductor testing technology, and in particular to a simple engineering vehicle that can be electrically lifted. Background Technology

[0002] In semiconductor testing, a vehicle is typically used to move the testing equipment. These vehicles are mainly divided into FT (Flexible Tolerant) vehicles and simpler vehicles. FT vehicles, within their rated load capacity, can move the testing equipment horizontally, vertically, forward and backward, and even tilt. However, FT vehicles are complex in structure, large in size, have poor maneuverability, and are very expensive to use. Simpler vehicles, within their rated load capacity, can move and tilt the testing equipment. Some models of simpler vehicles have lifting functions, but most do not, limiting their usability. Vehicles with lifting functions use manual lifting, which is relatively inefficient. Utility Model Content

[0018] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane".

[0019] like Figure 1-3 As shown, a preferred embodiment of a simple, electrically adjustable engineering vehicle is provided, comprising: a U-shaped base 1, an electrical control box 2, an electrically adjustable column 3, and a testing machine connection assembly. The lower end of the U-shaped base 1 is provided with several casters 11, and the upper end of the U-shaped base 1 is provided with the electrical control box 2. Two electrically adjustable columns 3 are provided on both sides of the U-shaped base 1, with one of the electrically adjustable columns 3 located close to the electrical control box 2. The testing machine connection assembly is provided on the two electrically adjustable columns 3, and both electrically adjustable columns 3 are connected to the electrical control box 2.

[0020] Furthermore, as a preferred embodiment, the caster 11 is preferably configured as a roller with a braking function so that the U-shaped base 1 can remain stable when the electric lifting column 3 and the flipping mechanism 7 drive the testing machine to move.

[0021] Furthermore, as a preferred embodiment, the testing machine connection assembly includes: a first clamping assembly, a second clamping assembly, and a flipping mechanism 7. The flipping mechanism 7 is disposed at the upper end of one of the electric lifting columns 3 and is connected to the second clamping assembly. The first clamping assembly is disposed at the upper end of the other electric lifting column 3, and the first clamping assembly and the second clamping mechanism are arranged opposite each other.

[0022] Furthermore, as a preferred embodiment, the first clamping assembly includes: a small shaft seat 5, a small shaft seat mounting plate 8, a first arm connecting plate 9, and a first clamping plate 4. The small shaft seat mounting plate 8 is disposed on the upper end of another electric lifting column 3. The small shaft seat 5 is installed on the small shaft seat mounting plate 8 by bolts. One end of the first arm connecting plate 9 extends into the small shaft seat 5 and is rotatably connected to the small shaft seat 5. The other end of the first arm connecting plate 9 is connected to the first clamping plate 4 by bolts.

[0023] Furthermore, as a preferred embodiment, the second clamping assembly includes: a second clamping plate 6, the second clamping plate 6 being connected to the flipping mechanism 7, and the first clamping plate 4 and the second clamping plate 6 being arranged facing each other.

[0024] Furthermore, as a preferred embodiment, the tilting mechanism 7 includes: a bearing seat 71, a bearing seat mounting plate 72, a second arm connecting plate 73, a tilting brake assembly 74, and a reducer assembly 75. The bearing seat mounting plate 72 is disposed on the upper end of one of the electric lifting columns 3. The bearing seat 71 is bolted to the bearing seat mounting plate 72. The tilting brake assembly 74 is connected to the end of the bearing seat 71 near the second clamping plate 6. In non-working state or emergency, the tilting brake assembly 74 can quickly brake to prevent the second clamping plate 6 from rotating accidentally. The reducer assembly 75 is connected to the end of the bearing seat 71 away from the second clamping plate 6. One end of the second arm connecting plate 73 passes through the tilting brake assembly 74 and the bearing seat 71 in sequence and is connected to the reducer assembly 75. The other end of the second arm connecting plate 73 is bolted to the second clamping plate 6. Furthermore, the reducer assembly 75 can be connected to an external drive motor. After the drive motor inputs power to the reducer assembly 75, the reducer assembly 75 can convert the high speed of the drive motor into a low speed and high torque output, thereby providing smooth power for the rotation of the second arm connecting plate 73. The smooth rotation of the second arm connecting plate 73 can drive the second clamping plate 6 to rotate smoothly.

[0025] Furthermore, as a preferred embodiment, both the rollover braking assembly 74 and the reducer assembly 75 are prior art, and therefore will not be described in detail here.

[0026] Furthermore, as a preferred embodiment, it also includes: a caster pad 12, wherein a caster pad 12 is provided between each caster 11 and the U-shaped base 1, and the caster pad 12 connects the caster 11 and the U-shaped base 1.

[0027] Furthermore, in a preferred embodiment, the upper end of the caster 11 has a mounting plate, and the caster pad 1 is bolted to the lower inner wall of the U-shaped base 1 and the mounting plate. The mounting plate is located on the lower inner side of the U-shaped base 1, and the caster 11 is embedded in the lower end of the U-shaped base 1. Furthermore, by embedding the caster 11 in the U-shaped base 1, the distance between the U-shaped base 1 and the ground is reduced, thereby improving the passability of the engineering vehicle.

[0028] Furthermore, in a preferred embodiment, both the first clamping plate 4 and the second clamping plate 6 are provided with a plurality of mounting holes, which can mate with threaded holes on the testing machine. Further, bolts can be installed in the mounting holes, and the bolts mate with the threaded holes on the testing machine, thus connecting the first clamping plate 4 and the second clamping plate 6 to the testing machine via bolts.

[0029] The working principle of this utility model is as follows: In use, the testing machine can first be installed on the first clamping plate 4 and the second clamping plate 6 by bolts. Then, the electric lifting column 3 can be raised and lowered by controlling the control box 2, thereby driving the first clamping assembly and the second clamping assembly to rise and fall. The testing machine installed on the first clamping plate 4 and the second clamping plate 6 will also rise and fall accordingly. Then, the drive motor is started, so that the second clamping plate 6 rotates under the drive of the drive motor. The rotation of the second clamping plate 6 can drive the testing machine to flip.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
