[0002] When processing certain thin-walled semiconductor components, there are high precision requirements for the flatness of the processed surface, especially for components made of easily deformable materials such as aluminum (AL6061) and stainless steel (SUS304). Their planar structure is prone to twisting and deformation during processing, making it difficult to meet the standard requirements and making clamping more difficult.

Furthermore, they cannot be adapted to the specifications of semiconductor components, leading to low practicality. After prolonged use, the surface of the processing table is prone to slight bulges that are difficult to observe with the naked eye, yet may affect the clamping of semiconductor components.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0020] Please see Figures 1-6 This embodiment provides a fixture for thin-walled semiconductor components, including a base 1 and an adjusting screw 2. A fixing groove is formed on the upper surface of the base 1. The adjusting screw 2 is rotatably mounted on the front end face of the fixing groove via a bearing. The adjusting screw 2 has symmetrical front and rear threads with opposite directions. Adjusting sliders are symmetrically screwed onto the outer wall of the adjusting screw 2. A positioning plate 11 is mounted on the upper surface of the adjusting slider. A fixing hole is formed on the outer end of the positioning plate 11. A positioning screw 12 is screwed into the fixing hole. A limit bracket 13 is rotatably mounted on the inner end of the positioning screw 12 via a bearing. Multiple suction cups 14 are embedded from left to right on the upper surface of the base 1. A first motor 15 is installed on the front end face of the adjusting screw 2. During operation, multiple semiconductor components are placed on the base 1, the first motor 15 is started, and the adjusting screw 2 is rotated. The positioning plate 11 moves inward, causing the limiting frame 13 to move inward, thereby clamping and fixing the multiple semiconductor components and effectively preventing them from being tilted. Then, the suction cup 14 is activated, which can attract and fix the bottom of the semiconductor components, further improving the fixing effect. Rotating the positioning screw 12 makes it easy to replace the limiting frame 13 according to the specifications of the semiconductor components, further improving the versatility of the device.
[0021] The limiting frame 13 is symmetrically equipped with positioning rods 16 on the left and right sides of its outer end. The positioning plate 11 is provided with positioning holes that cooperate with the positioning rods 16. The positioning rods 16 pass through the positioning holes. During operation, the positioning rods 16 are used to further ensure the stability of the limiting frame 13.
[0022] The base 1 has a top frame 17 installed on its left and right side walls. An electric slider 18 is installed on the top of the base frame. A base plate 21 is installed on the bottom of the electric slider 18 via a connecting rod 19. Multiple pressure sensing units 22 are embedded in the bottom of the base plate 21. A control panel 23 is installed on the left end face of the top frame 17. The control panel 23 is electrically connected to the pressure sensing units 22. The electric slider 18 is a linear guide slider structure. It controls the linear movement of the device by rotating the lead screw driven by the motor. The control panel 23 is programmed with a PLC to control the operation of each device. During operation, the electric slider 18 starts and controls the base plate 21 to move left and right. The bottom of the base plate 21 is in contact with the upper end face of the base 1. When the upper surface of the base 1 is slightly uneven, the pressure sensing units 22 are squeezed during the movement of the base plate 21, and the pressure changes. The signal is transmitted to the control panel 23. This situation can be observed by the control panel 23, so that the base 1 can be leveled and repaired in time to avoid affecting the clamping effect on semiconductor components.
[0023] A side plate 24 is installed on the left end face of the base 1. A cotton pad 25 is installed on the upper end face of the side plate 24 by adhesive. When in operation, when not in use, the base plate 21 moves onto the cotton pad 25, which not only provides shock absorption and protection but also serves a certain cleaning function.
[0024] The positioning plate 11 has a main cavity 26 installed on its outer end. An adjusting screw 27 is rotatably installed in the bottom of the main cavity 26 via a bearing. A first slider is installed on the outer wall of the adjusting screw 27. A connecting frame 28 is symmetrically installed on the left and right sides of the first slider. A connecting plate 29 is installed on the outer end of the connecting frame 28. Multiple insert rods 291 are installed at the bottom of the connecting plate 29. The insert rods 291 are inserted into the outer wall of the positioning screw 12. The left and right side walls of the main cavity 26 have symmetrical through holes. The connecting frame 28 passes through the through holes and is connected to them by sliding fit. During operation, the insert rods 291 position the adjusting screw 27 to prevent relative rotation and ensure the installation effect of the limiting frame 13. When the limiting frame 13 is disassembled, the adjusting screw 27 is rotated, which can drive the multiple insert rods 291 to move upward, making the operation convenient.
[0025] In actual operation, multiple semiconductor components are placed on the base 1. The first motor 15 is started, driving the adjusting screw 2 to rotate. The positioning plate 11 moves inward, causing the limiting frame 13 to move inward, thereby clamping and fixing the multiple semiconductor components and effectively preventing them from being tilted. Then, the suction cup 14 is activated, which can attract and fix the bottom of the semiconductor components, further improving the fixing effect. Rotating the positioning screw 12 makes it easy to replace the limiting frame 13 according to the specifications of the semiconductor components, further improving the versatility of the device.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model. Structures, devices, and operating methods not specifically described and explained in this utility model, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
