Technical Field

[0001] The utility model specifically relates to the technical field of semiconductor processing platforms, and specifically provides a semiconductor device processing platform with a rotary lifting structure. Background Art

[0002] A semiconductor refrigeration sheet, also called a thermoelectric refrigeration sheet, is a heat pump. Its advantages are that it has no sliding parts and is applied in some occasions where space is limited, reliability requirements are high, and there is no refrigerant pollution. Utilizing the effect of semiconductor materials, when direct current passes through an electric couple formed by two different semiconductor materials connected in series, heat can be absorbed and released at both ends of the electric couple respectively, and the purpose of refrigeration can be achieved. It is a refrigeration technology that generates negative thermal resistance, characterized by no moving parts and relatively high reliability. When processing semiconductor wafers, positioning is required to achieve rapid processing, and a special positioning processing platform is needed. However, the existing positioning processing platforms have poor convenience in installing external processing equipment and inconvenient adjustment, and cannot stably perform rapid positioning for semiconductor wafers. The convenience of adjustment after fixation is also poor. When processing different positions of the semiconductor refrigeration sheet during operation, movement is required. The existing processing platforms cannot drive the clamped semiconductor refrigeration sheet to rotate, lift, etc., which is troublesome to use. Summary of the Invention

[0003] The purpose of the utility model is to provide a semiconductor device processing platform with a rotary lifting structure to solve the problems of troublesome installation and positioning of the processing platform and inability to rotate and adjust the height as mentioned in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A semiconductor device processing platform with a rotary lifting structure includes a base. Both sides of the top of the base are fixedly connected with L-shaped support plates. The top of the L-shaped support plates is fixedly connected with both sides of the top of a cylinder. The bottom of the cylinder is fixedly connected to the middle of the base. The cylinder drives a first support rod to move. The top of the first support rod is fixedly connected with a clamping mechanism. A rotary mechanism is arranged at the bottom of the first support rod. The clamping mechanism is rotatably connected to a workbench. A placement rack is arranged on one side of the workbench, and a welding torch can be placed and clamped on the placement rack.

[0006] Preferably, the rotary mechanism includes a first rotating wheel. The first rotating wheel is connected to a second rotating wheel through a belt, and the second rotating wheel is driven to rotate by a motor.

[0007] Through the above technical solution, the motor drives the second rotating wheel to rotate to drive the first rotating wheel to rotate.

[0008] Preferably, the top end of a second support rod is fixedly connected to the bottom of the workbench, and the bottom end of the second support rod is fixedly connected to the L-shaped support plate.

[0009] Through the above technical solution, the support rod fixedly connects the workbench and the base, increasing stability and ensuring the fixation around the workbench.

[0010] Preferably, the clamping mechanism includes a turntable. A bidirectional lead screw is arranged inside the turntable. A moving block is slidably connected to the bidirectional lead screw. One end of the bidirectional lead screw is fixedly connected to a knob through bevel gears.

[0011] Through the above technical solution, the bidirectional lead screw makes the two moving blocks move relatively, and the turntable is also separated from the workbench and can rotate independently.

[0012] Preferably, an adjusting lead screw is fixedly connected to the middle of the moving block. A lower clamping plate is slidably connected to the adjusting lead screw. An upper clamping plate is fixedly connected to the top of one side of the moving block.

[0014] Preferably, the bottom end of a telescopic rod is fixedly connected to the top of the surface of the first rotating wheel, and the top end of the telescopic rod is fixedly connected to the bottom of the turntable.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: For the semiconductor device processing table with a rotary lifting structure, the motor rotates the second rotating wheel, the second rotating wheel drives the first rotating wheel to rotate, the first rotating wheel is rotatably connected to the first support rod at the shaft, and telescopic rods are fixedly connected to both sides of the first rotating wheel. Therefore, when the first rotating wheel rotates, the two telescopic rods can drive the top turntable to rotate. The telescopic member inside the cylinder is fixedly connected to the bottom of the first support rod. Therefore, the cylinder can control the lifting of the first support rod. The top of the first support rod is fixedly connected to the center of the turntable. Therefore, when the first support rod rises and falls, it can drive the turntable to rise and fall, and the workbench remains fixed. Multiple tools can be placed on one side of the workbench, reducing the operation difficulty and facilitating the processing of semiconductor refrigeration sheets at different positions during work.

[0021] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a semiconductor device processing table with a rotating and lifting structure according to the present invention;

[0022] As Figure 1 shown, both sides of the top of the base 1 are fixedly connected to the L-shaped support plate 2.

The bottom of the workbench 9 is fixedly connected to the top of the second support rod 7, and the bottom of the second support rod 7 is fixedly connected to the L-shaped support plate 2.

[0023] In the above solution, one end of the bottom of the L-shaped support plate 2 is fixedly connected to both sides of the top of the cylinder 3. The generating chamber of the welding torch 10 is fixedly connected to the outside of one of the L-shaped support plates 2. The generating chamber is fixedly connected to the welding torch 10 through a pipeline. The welding torch 10 can be hung on the placement rack on one side of the workbench 9 for storage. Both sides of the bottom of the workbench 9 are fixedly connected to the tops of the two second support rods 7. The second support rods 7 are arranged on both sides of the second rotating wheel 502 and the bottom of the second support rods 7 is fixedly connected to the bottom of the L-shaped support plate 2.

[0024] As Figure 2 shown, a rotating mechanism 5 is provided at the bottom of the first support rod 4. The rotating mechanism 5 includes a first rotating wheel 501. The first rotating wheel 501 is connected to the second rotating wheel 502 through a belt 503. The second rotating wheel 502 is driven to rotate by a motor 504. The top of the surface of the first rotating wheel 501 is fixedly connected to the bottom end of the telescopic rod 6, and the top end of the telescopic rod 6 is fixedly connected to the bottom of the turntable 801.

[0025] In the above solution, the motor 504 is fixedly connected to the outside of the L-shaped support plate 2 on the right side. A speed reducer for controlling the rotation speed of the motor 504 is installed at the output end of the motor 504, and then it is fixedly connected in the middle with the first rotating wheel 501. The outsides of the first rotating wheel 501 and the second rotating wheel 502 are concave-shaped, and the belt 503 is arranged in the concave part to connect the first rotating wheel 501 and the second rotating wheel 502.

[0026] As Figure 3 shown, the clamping mechanism 8 includes a turntable 801. A bidirectional lead screw 802 is arranged inside the turntable 801. A moving block 803 is slidably connected to the bidirectional lead screw 802. One end of the bidirectional lead screw 802 is fixedly connected to a knob 807 through bevel gears. An adjusting lead screw 804 is fixedly connected in the middle of the moving block 803. A lower clamping plate 805 is slidably connected to the adjusting lead screw 804.

[0027] In the above solution, the bottom diameter of the turntable 801 of the clamping mechanism 8 is larger than the diameter of the hole in the middle of the workbench 9.
