Description

TECHNICAL FIELD

[0001] The utility model belongs to the protection technical field for semiconductor production, concretely relates to a telescopic protective cover for semiconductor testing machine. BACKGROUND

[0002] Semiconductor testing machines play an important role in integrated circuit production and quality detection, and are usually used for detecting and evaluating the performance of semiconductor chips. However, during the semiconductor testing process, the service life and detection accuracy of the testing equipment can be adversely affected by factors such as particulate matter, static electricity, and changes in temperature and humidity in the testing environment. Therefore, semiconductor testing equipment is usually equipped with protective covers to protect the equipment and improve the testing environment.

[0003] The protective covers currently available on the market are usually fixed or simply foldable, and have the following shortcomings in design:

[0004] 1. Limited protection effect: The existing fixed protective covers cannot flexibly adjust the size of the protection area during the testing process, making it difficult to meet the needs of different equipment and testing environments.

[0005] 2. Complex replacement and maintenance: Once the fixed protective cover is damaged, it needs to be replaced as a whole, which is time-consuming and costly.

[0006] 3. Poor stability: Some telescopic protective covers are prone to jamming when moving and adjusting due to insufficient design of the guide rails or sliding mechanisms, affecting the continuity of equipment operation. UTILITY MODEL CONTENTS

[0007] In view of the problems in the prior art, the utility model aims to provide a telescopic protective cover for a semiconductor testing machine, which can not only meet the diversified protection needs of the equipment, but also quickly replace damaged parts when damaged, and ensure the stability and reliability of the overall use.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0009] A telescopic protective cover for a semiconductor testing machine, comprising a track strip, the track strip being fixed on one side of the testing machine by bolts, a fixed column being vertically arranged at one end of the upper surface of the track strip, a fixed bolt being vertically arranged on one side of the fixed column, a connecting rod being rotatably mounted on the surface of the fixed bolt, a plurality of connecting rods being hingedly connected end to end, a movable stand being slidably mounted on the upper surface of the track strip, the movable stand being arranged in parallel with the fixed column, wherein the connecting rod at the tail is hingedly connected to the movable stand, a clamping plate being symmetrically arranged at the bottom center of the connecting rod, a protective plate being mounted between the two clamping plates, a locking bolt being screwed on the outer side of one clamping plate, the protective plate being locked and fixed by the locking bolt, the width of the protective plate being equal to that of the connecting rod.

[0010] Further, the protective plate comprises a support plate, and the support plate is provided with a protective layer close to one side of the testing machine.

[0011] Further, the upper surface of the track strip is uniformly provided with positioning holes, and the two sides of the track strip are symmetrically provided with sliding grooves.

[0012] Further, the bottom of the moving stand is provided with a sliding seat, the sliding seat is in a U-shaped structure with an opening downward, and the two sides of the bottom of the sliding seat are respectively slid in the sliding grooves on the two sides.

[0013] Further, the front surface of the moving stand is provided with an open slot, a sliding rod is vertically and slidably arranged in the moving stand, a positioning bolt is fixed to the bottom of the sliding rod, and the positioning bolt is matched with the inner size of the positioning hole.

[0014] Further, the front side of the surface of the sliding rod is transversely fixed with an extension bolt, the extension bolt penetrates the open slot, a spring is placed above the moving stand, and the bottom of the spring is in contact with the upper end surface of the sliding rod.

[0015] Compared with the prior art, the protective plate of the utility model has the advantages that:

[0016] The protective plate is designed by multiple pieces, and is fixed between connecting rods through locking bolts, so that the protective plate can be flexibly adjusted in the protection range according to the use requirement. Each protective plate can be independently replaced without the need of overall disassembly, thereby significantly improving the maintenance efficiency and reducing the maintenance cost. In addition, the protective layer arranged on the surface of the protective plate has multifunctional properties such as flame retardation, waterproofness and corrosion resistance, thereby ensuring the applicability in complex testing environments and prolonging the service life of the protective cover.

[0017] Through the design of the connecting rods hingedly connected in multiple sections, the telescopic adjustment of the protective cover can be realized, the shape size requirement of different testing equipment can be adapted, and the defect that the existing fixed or simply folded protective cover cannot be flexibly adjusted is solved. The multi-point cooperation of the connecting rods with the track strip and the moving stand ensures the stability of the whole protective cover when being unfolded and retracted, and avoids the influence of running jam on the normal operation of the testing equipment.

[0018] In the utility model, the cooperation design of the sliding rod and the spring utilizes the continuous downward force of the spring on the sliding rod to ensure that the positioning bolt and the positioning hole can be automatically aligned and firmly locked. When adjustment is needed, the sliding rod is separated from the positioning by lifting the extension bolt, and the free sliding of the moving stand is realized. This scheme effectively solves the problem of unstable positioning in the existing device, and ensures the convenience of adjustment and locking operation. BRIEF DESCRIPTION OF DRAWINGS
