Description

Technical Field

[0001] This utility model belongs to the field of precision optical component assembly tools, and is particularly suitable for the combination ring vacuum pen for picking up and assembling components such as ring spacers, filters, and molded injection lenses that need to avoid contact with the light-transmitting aperture area. Background Technology

[0002] Traditional magnetic pens easily come into contact with the light-transmitting areas of optical components during adsorption, leading to scratches, dust contamination, and stray light issues. Especially in high-precision optical assembly scenarios, such damage can cause irreversible defects such as stray light scattering and image blurring. Existing technologies lack dedicated adsorption structures for ring-shaped components, making it impossible to simultaneously achieve non-contact adsorption and pressure assembly functions.

[0003] 1. Contact damage to the light-transmitting area: When traditional suction pens adsorb optical components, they directly contact the light-transmitting aperture area, which can easily cause surface scratches and micro-dust contamination. Scratches lead to stray light scattering and blurred imaging, and the introduction of contamination requires additional cleaning procedures.

[0004] 2. Uncontrollable airflow pollution: The suction airflow carries dust particles that directly affect the light-transmitting surface, which exacerbates the pollution risk, especially in scenarios such as filter bonding and lens assembly.

[0005] 3. Functional limitations: There is a lack of dedicated adsorption structures for annular spacers and edge plane lenses; existing tools cannot simultaneously achieve non-contact adsorption and compression assembly functions. Utility Model Content

[0006] This invention aims to overcome the shortcomings of the prior art by providing a combined annular vacuum suction pen that only adsorbs non-light-transmitting areas at the edges of components, avoids airflow dust contamination, and supports pressing and assembly operations.

[0007] To solve the above-mentioned technical problems, this utility model is implemented as follows: A combined annular vacuum suction pen includes an air tube control device, a suction pen inner core, and an outer cylinder sleeved around the suction pen inner core; a clearance area is provided at the bottom of the suction pen inner core; an annular air gap is formed between the suction pen inner core and the outer cylinder, and the annular air gap is located in a non-light-transmitting aperture area; the gas medium transmission port of the air tube control device is connected to the annular air gap.

[0008] Furthermore, the lower side wall of the pen core is provided with a ventilation window; a drainage channel is provided on the ventilation window; a main channel is provided longitudinally inside the pen core; the gas medium transmission port of the air pipe control device is connected to the main channel; the main channel is connected to the drainage channel and the annular air gap to buffer sudden airflow changes.

[0009] Furthermore, the upper part of the outer cylinder is airtight with the outer wall of the inner core of the pen through a sealing ring, and its lower contact surface is on the same plane as the bottom end of the inner core of the pen.

[0010] Furthermore, a central boss is provided laterally in the upper region of the inner core of the pen; the top contact surface of the outer cylinder is connected to the bottom of the central boss.

[0011] Furthermore, the depth of the avoidance area is adjustable.

[0012] Furthermore, the ring wall of the avoidance area can adopt a ring wall structure with adjustable thickness.

[0013] This invention features a ring-shaped adsorption system that avoids contact with light-transmitting areas, reducing scratches and dust contamination. Its modular design facilitates replacement and maintenance. The outer cylinder's front end can press down on components, improving assembly precision. This invention uses an annular air gap between the inner core and outer cylinder to strictly limit adsorption to the non-light-transmitting area at the component's edge, physically isolating the light-transmitting aperture. The pressing function of the outer cylinder's front annular wall completes component assembly and positioning simultaneously with adsorption. The modular inner core / outer cylinder design and airflow buffer structure reduce maintenance costs and improve operational stability.

[0014] Compared to commonly available suction pens, this invention effectively avoids contact with the central light-transmitting aperture area by suctioning the edge region of the annular component, thus reducing the contact area. During the placement and assembly process, it effectively prevents scratches or contamination of the light-transmitting aperture surface, reducing stray light and image blurring caused by scratches, thereby improving the image quality after assembly. In the annular gas channel at the tip of the suction pen, gas mainly flows through the annular edge region, effectively reducing the impact of dust carried by the airflow on the light-transmitting aperture surface. This design is particularly suitable for the placement and assembly of annular spacers, and also applicable to the placement and assembly of planar optical filters, molded lenses (edge ​​plane, central convex or concave surface), and other components. For example, it reduces the introduction of dust during the bonding and encapsulation of filters; reduces the impact of dust during lens assembly; and reduces dust contamination in biological sample processing.

[0018] like Figures 1-3 As shown, the combined annular vacuum suction pen includes an air tube control device 3, a suction pen inner core 1, and an outer cylinder 2 that is fitted with the suction pen inner core; an avoidance area 101 is provided at the bottom of the suction pen inner core 1; an annular air gap 4 is formed between the suction pen inner core 1 and the outer cylinder 2, and the annular air gap is located in the non-light-transmitting aperture area; the gas medium transmission port of the air tube control device 3 is connected to the annular air gap 4.

[0019] The lower side wall of the inner core 1 of the present invention is provided with a ventilation window 102; a drainage channel 103 is provided on the ventilation window 102; a main channel 104 is provided longitudinally inside the inner core 1; the gas medium transmission port of the air pipe control device 3 is connected to the main channel 104; the main channel 104 is connected to the drainage channel 103 and the annular air gap 4 to buffer sudden airflow changes.

[0020] The outer cylinder 2 of this invention achieves airtightness with the outer wall of the inner core 1 via a sealing ring 5, and its lower contact surface 201 is on the same plane as the bottom of the inner core 1. A central boss 105 is laterally provided in the upper region of the inner core 1; the top contact surface of the outer cylinder 2 is in contact with the bottom of the central boss 105. The depth of the clearance area 101 is adjustable, meaning the depth can be adjusted during design according to actual application requirements. The ring wall 106 of the clearance area 101 can adopt an adjustable thickness ring wall structure.

[0021] In its specific design, this utility model is assembled from three parts: an inner core 1, an outer cylinder 2, and an air tube control device 3 connected to the rear end. The suction pen adopts a modular design, making assembly simple and maintenance easy. Each component can be replaced according to actual usage, thereby reducing usage and maintenance costs. Its working principle is as follows: Through the slotted holes on both sides of the front end of the inner core and the partial sealing effect of the outer cylinder, airflow extraction and discharge are ensured, achieving effective airflow. The air gap at the lower end of the suction pen is used to pick up and place items, and during the suction process, it reduces the impact of micro-dust carried in the airflow on the surface of the light-transmitting aperture. Furthermore, the lower ring of the outer cylinder can further compress external parts, preventing scratches on the convex surface of the lens. Protective chamfers can be provided on the contact surfaces, and the specific dimensions can be adjusted according to actual usage requirements.

[0022] The inner core tail 107 is mainly used to connect with the air tube in the air tube control device 3 to generate suction. It is usually designed as a cylinder or other suitable shape to ensure good airtightness. The inner core central boss 105 is located in the upper area of ​​the inner core 1 of the suction pen, and includes a sealing contact surface and internal airflow channel design to ensure the functionality and stability of the entire device. The lower part 108 of the inner core is the part that directly contacts the object being adsorbed. Its design needs to consider factors such as friction and contact area to achieve the best adsorption effect. The vent 102 allows air to pass through and is crucial for controlling the suction strength. Its shape can be circular, rectangular, etc., and the choice of shape should be based on the actual application scenario to achieve optimal performance. The main channel 104 is a key part for connecting the internal and external airflow, ensuring that the airflow can enter and exit smoothly, thereby adjusting the suction strength. The diameter of the vent can be determined according to specific needs to achieve the ideal suction control effect. The outer ventilation channel 103 is mainly used to guide the external airflow and also plays a certain buffering role. Through a well-designed buffer system, especially during the start and stop of suction, sudden changes in internal pressure caused by abrupt airflow changes are prevented. This improves consistency and stability. The avoidance zone 101 is specifically designed to prevent interference with other components, such as optical elements or sensors. Its diameter and height can be adjusted according to actual application requirements. The shape of the avoidance zone can be cylindrical or other forms, depending on the obstacle to be avoided. The ring wall 106 is a ring-shaped structure. The ring wall structure helps reduce the contact area for suction and can be adjusted to suit different usage and load requirements by adjusting the ring wall thickness. The inner core front end height refers to the height of the pen's front end, which can be specified comprehensively based on actual operating feel, suction efficiency, and consistency.

[0023] See Figure 3 As shown, the outer cylinder 2 serves as the outer protective shell for the pen core, supports the inner core assembly, and forms the airflow channel. The sealing ring 5 is located at the top of the outer cylinder. The sealing ring ensures a relative seal through the sealing compression of the elastic rubber ring. Material: A material with sealing and elasticity, such as rubber or silicone, is selected. The lower contact surface 201 of the outer cylinder 2 forms a ring-shaped structure. The design of the ring wall 106 helps reduce the contact area for suction and can be adjusted to meet different usage and load requirements by adjusting the ring wall thickness. 4 is the annular air gap between the pen core 1 and the outer cylinder 2, used for suction and release operations on the annular area at the edge of the non-light-transmitting aperture.

[0024] The inner core 1 of the suction pen is the core component of the suction pen. It is typically made of plastic or metal (material is not limited), and has a long, thin shape. It is inserted into the outer cylinder to form a relatively sealed portion, ensuring close contact with the object's surface. The inner core contains small windows and channels to guide airflow. The outer cylinder 2 surrounds the inner core 1, forming an annular air gap 4. The annular air gap 4 creates negative pressure, allowing the suction pen to attract objects. The annular air gap 4 between the inner core 1 and the outer cylinder 2 is controlled by an air tube in the air tube control device 3 to perform suction and release operations on the annular area at the edge of the non-transparent aperture. The air tube control device 3 is connected to the outer cylinder 2, and the pressure difference between the inner core and the outer cylinder is adjusted by controlling the inflow and outflow of gas. The control device may include valves, pipes, connectors, and other components to control the airflow. See also...
