Description

Technical Field

[0001] This utility model relates to the field of biosensor technology, and in particular to an apparatus for fabricating biosensor chips. Background Technology

[0002] A biosensor chip is a miniature device that integrates biometric elements and signal transduction mechanisms. Its internal components work together to achieve efficient detection of target analytes and are widely used in fields such as medical diagnosis, environmental monitoring, and food safety.

[0003] In the prior art, a search revealed a Chinese patent disclosing "An apparatus for fabricating a biosensor chip," application number "202121738277.6." This patent mainly includes an etching chamber, an LSPR biosensor chip assembly mechanism, and a substrate frame. A crossbeam is mounted above the etching chamber and the LSPR biosensor chip assembly mechanism, and a drive mechanism is installed on the crossbeam. The substrate frame is detachably mounted on the drive mechanism, which drives the substrate frame to move horizontally and vertically. While this patent uses a drive mechanism to move the substrate frame horizontally and vertically, replacing manual operation and enabling continuous production, thus improving efficiency, the length and flexibility of the wire rope used to move the substrate frame up and down and left and right in the processing area, along with the second motor, wire reel, and wire rope, can easily cause the substrate frame to sway during movement. The instability of the substrate frame makes it prone to collisions with the various chambers, thus affecting the stability of the biosensor substrate within the frame. Furthermore, the movement of the substrate frame between chambers requires reciprocating winding of a steel wire rope for vertical movement, resulting in low substrate transport efficiency. Therefore, this invention provides an apparatus for fabricating a biosensor chip to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to provide a device for fabricating biosensor chips. A horizontally movable plate drives a mounting plate to move on a corrugated guide rail, which enables stable up-and-down movement of the substrate frame on the corrugated guide rail and allows for processing at the troughs of the corrugations. This improves the fabrication efficiency and quality of biosensor chips and has a simple structure.

[0005] To achieve the above objectives, an apparatus for fabricating a biosensor chip is provided, comprising a mounting frame, a processing component, and a substrate frame. The mounting frame is U-shaped with a hollow interior. A movable plate is slidably connected inside the hollow structure of the mounting frame. A driving component for moving the movable plate horizontally is provided on the mounting frame. Two adjacent guide rails are fixedly connected to one side of the mounting frame. Both guide rails are wavy and form a guide portion between them. A U-shaped mounting plate is sleeved on the outer side of the guide rails. A first roller that rolls inside the guide portion is rotatably connected to the inner side of the mounting plate. A connecting rod is fixedly connected to the bottom of the mounting plate. The substrate frame is mounted on the bottom end of the connecting rod. An L-shaped driving plate is fixedly connected to the side of the movable plate near the guide rails. A sliding groove is formed inside the driving plate, and a slider that is fixedly connected to the mounting plate is slidably connected inside the sliding groove.

[0006] According to the apparatus for fabricating a biosensor chip, the driving component includes a lead screw rotatably connected inside the hollow structure of the mounting frame and a motor fixedly connected to one side of the mounting frame. The movable plate is threadedly connected to the lead screw, and the end of the lead screw near the motor passes through the mounting frame and is fixedly connected to the output shaft of the motor.

[0007] According to the apparatus for fabricating a biosensor chip, the peaks and troughs of the guide rail are both designed to be horizontal.

[0008] According to the apparatus for fabricating a biosensor chip, a plurality of second rollers are mounted on one side of the mounting plate near the two sides of the guide rail, and the second rollers are in rolling connection with the side of the guide rail.

[0009] According to the apparatus for fabricating a biosensor chip, the processing component is located below the trough.

[0010] According to the apparatus for fabricating a biosensor chip, the substrate frame has multiple substrate slots inside and is detachably mounted on the bottom end of the connecting rod.

[0011] This utility model has the following beneficial effects:

[0012] Compared with existing technologies, this device for fabricating biosensor chips uses a horizontally movable plate to drive the mounting plate to move on a corrugated guide rail.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4This utility model discloses an apparatus for fabricating a biosensor chip, comprising a mounting frame 1, a processing component 2, and a substrate frame 9. The mounting frame 1 has a U-shaped structure and a hollow interior. A movable plate 3 is slidably connected inside the hollow structure of the mounting frame 1. The mounting frame 1 is equipped with a drive component for driving the movable plate 3 to move horizontally. Two adjacent guide rails 4 are fixedly connected to one side of the mounting frame 1. Both guide rails 4 have a wave-shaped structure and form a guide portion 14 between them. A U-shaped mounting plate 11 is sleeved on the outer side of the guide rails 4. A first roller 12 is rotatably connected to the inner side of the mounting plate 11 and rolls inside the guide portion 14, allowing the mounting plate 11 to move along the wave-shaped path of the guide rails 4. A connecting rod 8 is fixedly connected to the bottom of the mounting plate 11, and the substrate frame 9 is mounted on the bottom end of the connecting rod 8. An L-shaped drive plate 7 is fixedly connected to the side of the movable plate 3 near the guide rails 4. A groove 13 is formed inside the drive plate 7, and a slider 10 fixedly connected to the mounting plate 11 is slidably connected inside the groove 13.

[0023] When the horizontally moving movable plate 3 drives the drive plate 7 to move, the cooperation between the slider 10 and the slide groove 13 can drive the mounting plate 11 and its first roller 12 to move horizontally. When the first roller 12 moves inside the guide part 14, the mounting plate 11 moves along the wavy path of the guide rail 4. When the substrate frame 9 moves to the trough position with the mounting plate 11, the substrate frame 9 moves into the processing assembly 2, where the substrate inside the substrate frame 9 can be processed. After processing is completed inside the processing assembly 2, the continuous movement of the movable plate 3 drives the mounting plate 11 and its bottom substrate frame 9 to move upward to the trough position, thereby facilitating the next processing step. This enables the substrate frame 9 to move stably on the wavy guide rail 4 and can be processed at the trough position, improving the fabrication efficiency and quality of the biosensor chip.

[0024] The drive assembly includes a lead screw 5 rotatably connected to the hollow structure inside the mounting frame 1 and a motor 6 fixedly connected to one side of the mounting frame 1. The movable plate 3 is threadedly connected to the lead screw 5, and the end of the lead screw 5 near the motor 6 passes through the mounting frame 1 and is fixedly connected to the output shaft of the motor 6.

[0025] Driven by the motor 6, the lead screw 5 rotates, causing the movable plate 3 to move horizontally along the mounting frame 1.

[0026] The guide rail 4 has horizontal peaks and troughs, and its bottom is also horizontal. This ensures the stability of the mounting plate 11 and its bottom substrate frame 9 within the processing assembly 2, guaranteeing their stability. The processing assembly 2 is located below the troughs and includes an etching chamber and an LSPR biosensor chip assembly mechanism arranged from left to right. These components are used to process the substrate within the substrate frame 9, performing steps such as coating and etching required for biosensor chip fabrication.

[0027] Multiple second rollers 15 are installed on one side of the mounting plate 11 near the two sides of the guide rail 4. The second rollers 15 are in rolling connection with the side of the guide rail 4, which enhances the stability and smoothness of the movement of the mounting plate 11 on the guide rail 4.

[0028] The substrate frame 9 has multiple substrate slots inside and is detachably mounted on the bottom of the connecting rod 8. The substrate slots can accommodate and fix the substrate of the biosensor chip. The detachable substrate frame 9 is easy to clean or replace.

[0029] Working principle:

[0030] Driven by motor 6, lead screw 5 rotates, causing movable plate 3 to move horizontally along mounting frame 1. As movable plate 3 moves horizontally, driving drive plate 7, the cooperation of slider 10 and slide groove 13 drives mounting plate 11 and its first roller 12 to move horizontally. When the first roller 12 moves inside guide section 14, mounting plate 11 moves along the wavy path of guide rail 4. When substrate frame 9 moves with mounting plate 11 to the trough position, it moves into processing assembly 2, allowing processing of the substrate within substrate frame 9. After processing is completed inside processing assembly 2, the continuous movement of movable plate 3 drives mounting plate 11 and its bottom substrate frame 9 upwards to the trough, facilitating the next processing step. This enables stable movement of substrate frame 9 on wavy guide rail 4 and allows processing at the trough position, improving the fabrication efficiency and quality of biosensor chips.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
