Description

Technical Field

[0001] This utility model relates to the field of optical inspection, specifically to an optical inspection station with micro-ventilation for efficient solvent control. Background Technology

[0002] During manual visual inspection of optical lenses, cotton swabs are used to clean the lens surface with organic solvents such as ether, ethanol, and acetone. After use, the swabs and solvents are left exposed on the table, allowing the organic solvents to continuously evaporate into the air. These organic solvents not only irritate the eyes and respiratory system of workers, causing damage to the central nervous system, but also increase the risk of fire and explosion as they accumulate in the workplace. Due to the cleanliness requirements of the process, axial flow fans cannot be installed on the exterior walls of the optical lens inspection area for ventilation.

[0003] Existing optical inspection benches only have manual visual inspection capabilities and lack organic solvent collection devices. If local exhaust hoods are installed on the side or above the inspection bench, they are often too far away to allow for rapid collection of organic solvents at the initial stage of their generation, resulting in poor solvent control. The cleanroom air conditioning system is designed only for fresh air intake for personnel, neglecting the air volume required to exhaust organic solvents, leading to insufficient air changes during actual operation. Relying solely on the daily air conditioning system for whole-room dilution exhaust provides only a limited reduction in organic solvent concentration, failing to achieve the desired control effect. Increasing the daily air conditioning system exhaust volume would disrupt the cleanroom's thermal balance, necessitating a simultaneous increase in the air supply volume, significantly increasing the air conditioning system's operating load, workshop energy consumption, and overall operating costs.

[0004] Therefore, a new intelligent control technology for small-volume solvent zoning is needed to efficiently control the disorderly diffusion of organic solvents in optical lens testing sites. Utility Model Content

[0005] This application provides an optical inspection station with micro-ventilation for efficient solvent control, which solves the technical problems mentioned in the prior art and achieves the goal of controlling airflow to protect workers and control liquid evaporation and dispersion.

[0006] The technical problem solved by this utility model can be achieved by the following technical solution:

[0007] An optical inspection station with efficient solvent control via micro-exhaust ventilation includes a negative pressure system, comprising:

[0008] Vertical board;

[0009] The inspection chamber is fixed to the left side of the front surface of the vertical plate, and the inspection chamber is covered with an anti-reflective layer.

[0010] The top plate is fixed to the right side of the front surface of the vertical plate, and the upper surface of the top plate is on the same horizontal plane as the upper surface of the inspection chamber.

[0011] A shelf is fixed to the right side of the front surface of the vertical plate and is located below the top plate. The top plate and the shelf together form a reagent storage area.

[0012] The right side panel is fixed to the right side of the vertical panel, the top panel, and the storage panel, and the top of the right side panel is aligned with the lower right surface of the top panel.

[0013] The exhaust section is fixed between the inspection chamber and the top plate and the storage plate, and the exhaust section is connected to the inside of the inspection chamber;

[0014] An exhaust vent is provided on the vertical plate and is connected to the exhaust section. The negative pressure system is connected to the exhaust vent.

[0015] The inspection light source is detachably connected to the upper surface of the inspection chamber, and the upper surface of the inspection chamber has a light-transmitting hole, on which the inspection light source is located;

[0016] The control unit is detachably connected to the vertical plate and located at the rear of the inspection chamber. The control unit is electrically connected to the negative pressure system, the exhaust unit and the inspection light source.

[0017] Furthermore, the inspection chamber has a rectangular structure and consists of a left side plate, an upper plate, a bottom plate, and a light-shielding plate. The left side plate is vertically fixed to the left side of the vertical plate. The upper plate is fixed between the left side plate and the upper end of the exhaust section, and the rear side of the upper plate is fixed to the front surface of the vertical plate. The upper plate has a light-transmitting hole, and the inspection light source is detachably connected to the upper surface of the upper plate. The bottom plate is fixed between the left side plate and the lower end of the exhaust section, and the rear side of the bottom plate is fixed to the front surface of the vertical plate. The two sides of the light-shielding plate are slidably connected between the opposite front surfaces of the left side plate and the exhaust section. The opposite surfaces of the left side plate, the upper plate, the bottom plate, the light-shielding plate, and the exhaust section are all covered with an anti-reflective coating. The space between the left side plate, the upper plate, the bottom plate, and the exhaust section is the visual inspection chamber.

[0018] Furthermore, a partition is vertically fixed between the left side panel and the exhaust section, and a drawer is slidably connected between the partition and the bottom plate. The upper surface of the partition is covered with an anti-reflective coating.

[0019] Furthermore, the exhaust section comprises a pair of exhaust perforated plates, a drive unit, and a guide plate. The front sides of the pair of exhaust perforated plates are fixedly connected to each other, and the rear sides of the pair of exhaust perforated plates are fixed to the front surface of the vertical plate. The pair of exhaust perforated plates form a V-shaped structure. The top ends of the pair of exhaust perforated plates are vertically fixed to the lower surface of the upper plate, and the lower ends of the pair of exhaust perforated plates are vertically fixed to the upper surface of the bottom plate. The front side of the guide plate is hinged between the front sides of the pair of exhaust perforated plates. The drive unit is detachably connected between the pair of exhaust perforated plates, and the drive end of the drive unit is hinged to the guide plate. The exhaust port is located between the pair of exhaust perforated plates. The drive unit is electrically connected to the control unit. One of the exhaust perforated plates is located on the left side of the plate and is covered with an anti-reflective coating.

[0020] Furthermore, the area of ​​the guide plate is at least greater than or equal to 50% of the area of ​​the exhaust orifice plate, the height or width of the guide plate can be selected as 1 / 2 to 2 / 3 of the height or width of the exhaust orifice plate, and the initial angle of the guide plate is 1 / 4 to 1 / 2 of the included angle between a pair of V-shaped combined exhaust orifice plates.

[0021] Furthermore, the drive unit consists of a pair of electric push rods. The tail ends of the pair of electric push rods are respectively hinged to the opposite surfaces of a pair of exhaust orifice plates, and the front ends of the pair of electric push rods are respectively hinged to the two sides of the guide plate. Each exhaust orifice plate has a placement groove. The tail ends of the electric push rods are hinged in the placement grooves, and the depth of the placement grooves is greater than the diameter of the electric push rods. The length of the placement grooves is greater than the total length of the electric push rods when the front ends are not extended. The electric push rods are electrically connected to the control unit.

[0022] Furthermore, a slide plate is slidably connected to the rear side of the guide plate, and the front ends of a pair of electric push rods are respectively hinged to the two sides of the slide plate.

[0023] Furthermore, a rotating shaft is detachably connected between the pair of exhaust orifice plates, the guide plate is hinged on the rotating shaft, and an indicator is detachably connected to the top of the rotating shaft extending upward through the upper plate. The indicator is used to provide real-time feedback on the rotation angle of the guide plate.

[0024] Furthermore, a human body sensor is detachably connected to the front surface of the vertical plate. The human body sensor is located between the left side plate and the exhaust section, and the human body sensor is electrically connected to the control unit.

[0025] Furthermore, the included angle between a pair of exhaust perforated plates in the V-shaped structure combination is 15~45°, the porosity is 10%~30%, and the opening diameter is 3mm~8mm.

[0026] Furthermore, the testing light source is an explosion-proof lighting source.

[0027] The beneficial effects of this utility model are: due to the adoption of an anti-reflective layer, the problem of uneven illumination caused by light reflection in the inspection cavity when the inspection light source emits light is effectively solved, thereby ensuring that the light from the inspection light source is not affected by reflection after entering the inspection cavity, thus preventing uneven illumination when the light shines outward through the inspection cavity.

[0028] Because a pair of exhaust perforated plates are used, and the pair of exhaust perforated plates are combined in a V-shape, the problem of simultaneous exhaust of the visual inspection chamber and the reagent storage area is effectively solved. By controlling the guide plate to partially cover one of the exhaust perforated plates, the air volume of the exhaust of the visual inspection chamber and the reagent storage area can be controlled in zones. At the same time, less exhaust effect is retained on this side, achieving a reasonable distribution effect.

[0029] Thanks to the use of a human body sensor, automated control is effectively achieved. The human body sensor can identify whether there are staff members operating in front of the inspection cavity, and then work with the control unit to achieve automated preset control, so that the guide plate moves to the position of that mode.

[0030] The use of a sliding plate effectively solves the problem of insufficient airflow during reagent pouring, thereby achieving full coverage of the exhaust vent plate on the other side, increasing the exhaust volume on this side, and reducing the escape of volatile gases.

[0031] By using a top plate and a shelf, along with the workbench, the reagent storage area forms a front-opening structure, which allows the airflow trajectory to cover the reagent storage area during exhaust. At the same time, the shelf allows for the utilization of the upper space.

[0032] Because of the use of a control unit, the control unit can preset modes, which are divided into normal mode, working mode and emergency mode. In normal mode, the reagent storage area is the main exhaust area, in working mode the visual inspection chamber is the main exhaust area, and in emergency mode the baffle can be controlled to fully cover the exhaust vent plate on one side.

Detailed Implementation

[0039] Example 1:

[0040] Reference Figure 1-4 This is a structural schematic diagram of Embodiment 1 of the present invention, an optical inspection station for efficient solvent control with micro-exhaust ventilation, including a negative pressure system 7, comprising:

[0041] Vertical board 1;

[0042] Inspection chamber 2, which is fixed to the left side of the front surface of vertical plate 1, and is covered with an anti-reflective layer;

[0043] Top plate 3, the top plate 3 is fixed to the right side of the front surface of the vertical plate 1, and the upper surface of the top plate 3 and the upper surface of the inspection chamber 2 are on the same horizontal plane;

[0044] The shelf 4 is fixed to the right side of the front surface of the vertical plate 1 and is located below the top plate 3. The top plate 3 and the shelf 4 are combined to form a reagent storage area.

[0045] The right side plate 5 is fixed to the right side of the vertical plate 1, the top plate 3 and the shelf 4, and the top of the right side plate 5 is adjacent to the lower right side surface of the top plate 3.

[0046] The exhaust section is fixed between the inspection chamber 2, the top plate 3, and the storage plate 4, and the exhaust section is connected to the interior of the inspection chamber 2.

[0047] The exhaust vent 6 is installed on the vertical plate 1 and is connected to the exhaust section. The negative pressure system 7 is connected to the exhaust vent 6.

[0048] The inspection light source 8 is detachably connected to the upper surface of the inspection chamber 2. The upper surface of the inspection chamber 2 has a light-transmitting hole, and the inspection light source 8 is located on the light-transmitting hole.

[0049] The control unit 18 is detachably connected to the vertical plate 1 and located on the rear side of the inspection chamber 2. The control unit is electrically connected to the negative pressure system 7, the exhaust unit and the inspection light source 8 respectively.

[0050] In actual use: The testing table is placed on the tabletop of the workbench. At this time, the bottom of the reagent storage area is covered by the tabletop of the workbench, so that the reagent storage area forms a structure with an opening on the front. Tools and reagents are placed on the tabletop of the workbench below the top plate 3 and on the shelf 4. Optical testing of the lens is performed in front of the testing chamber 2.

[0051] Electrically connect the sub-control module of the negative pressure system 7 in the workshop to the control unit 18, and connect the negative pressure system 7 to the exhaust port 6, so that the negative pressure system 7 exhausts air through the exhaust section, allowing the air in front of the test chamber and the reagent storage area to enter the exhaust section and then enter the negative pressure system 7 through the exhaust port 6.

[0052] When the exhaust system is in operation, it is divided into normal mode, working mode and emergency mode. In normal mode, the exhaust volume of the reagent storage area is higher than that of the test chamber, and vice versa. In emergency mode, the reagent storage area or test chamber 2 is completely sealed, allowing air to enter completely through the reagent storage area or test chamber 2, thereby instantly increasing the exhaust effect and reducing gas escape.

[0053] The anti-reflective layer prevents the light from the inspection light source 8 from being reflected inside the inspection chamber, thus avoiding uneven light during optical inspection.

[0054] The control unit 18 has explosion-proof characteristics and can be programmed to modify mode parameters. It can also control the inspection light source 8 to make the brightness controllable and adjustable.

[0055] The anti-reflective layer can be made of black velvet or black paint, and its main purpose is to prevent light reflection.

[0056] The negative pressure system has an exhaust volume of 100~500m³. 3 / h.

[0057] The solvent storage area is used to store organic solvents and cotton swabs used in testing. Organic solvents include ethyl acetate, acetone, and diethyl ether.

[0058] The test light source 8 uses an explosion-proof lighting source, which effectively reduces the safety risk of continuous emission of flammable and explosive organic solvents in the place, and the accumulation of concentration in a relatively confined space, which could lead to combustion and explosion.

[0059] Example 2:

[0060] Reference Figure 1-4The difference in this embodiment is that the inspection chamber 2 has a rectangular structure and is composed of a left side plate 9, an upper plate 10, a bottom plate 11, and a light-shielding plate 12. The left side plate 9 is vertically fixed to the left side of the vertical plate 1. The upper plate 10 is fixed between the left side plate 9 and the upper end of the exhaust section, and the rear side of the upper plate 10 is fixed to the front surface of the vertical plate 1. The upper plate 10 has a light-transmitting hole. The inspection light source 8 is detachably connected to the upper surface of the upper plate 10. The bottom plate 11 is fixed between the left side plate 9 and the lower end of the exhaust section, and the rear side of the bottom plate 11 is fixed to the front surface of the vertical plate 1. The two sides of the light-shielding plate 12 are slidably connected between the left side plate 9 and the front opposite surfaces of the exhaust section. The opposite surfaces of the left side plate 9, the upper plate 10, the bottom plate 11, the light-shielding plate 12, and the exhaust section are all covered with an anti-reflective coating. The space between the left side plate 9, the upper plate 10, the bottom plate 11, and the exhaust section is the visual inspection chamber 13.

[0061] In actual use: The operator sits in front of the workbench and in front of the visual inspection chamber 13, then opens the light shield 12, slides the light shield 12 upward, and controls the light shield 12 to slide to a suitable position and lock it according to the operator's work habits. At the same time, the control unit controls the inspection light source 8 to turn on and the exhaust unit to work, so that the exhaust unit is adjusted to the working mode. The air in front of the visual inspection chamber 13 enters the exhaust unit through the visual inspection chamber 13, completing the preparation before work.

[0062] The light irradiation distance of the inspection light source 8 is limited by the left side plate 9, the upper plate 10, and the bottom plate 11, so that only the front of the inspection cavity 13 is exposed to light, which facilitates optical inspection by the staff.

[0063] Example 3:

[0064] Reference Figure 1-3 The difference in this embodiment is that: a partition 14 is vertically fixed between the left side plate 9 and the exhaust section, a drawer 15 is slidably connected between the partition 14 and the bottom plate 11, and the upper surface of the partition 14 is covered with an anti-reflective coating.

[0065] In actual use: Drawer 15 can be used for storage, improving the utilization rate of the inspection table, and at the same time, it makes it convenient for staff to access tools used during optical inspection, such as storing cotton swabs, organic solvent glass bottles and other small tools.

[0066] Example 4:

[0067] Reference Figure 1-3The difference in this embodiment is that: the exhaust section consists of a pair of exhaust perforated plates 16, a drive unit, and a guide plate 17. The front sides of the pair of exhaust perforated plates 16 are fixedly connected to each other, the rear sides of the pair of exhaust perforated plates 16 are fixed to the front surface of the vertical plate 1, the pair of exhaust perforated plates 16 form a V-shaped structure, the top ends of the pair of exhaust perforated plates 16 are vertically fixed to the lower surface of the upper plate 10, and the lower ends of the pair of exhaust perforated plates 16 are vertically fixed to the upper surface of the bottom plate 11. The front side of the guide plate 17 is hinged between the front sides of the pair of exhaust perforated plates 16. The drive unit is detachably connected between the pair of exhaust perforated plates 16. The drive end of the drive unit is hinged to the guide plate 17. The exhaust port 6 is located between the pair of exhaust perforated plates 16. The drive unit is electrically connected to the control unit 18. One of the exhaust perforated plates 16 is located on the left side of the left plate 9 and is covered with an anti-reflective coating.

[0068] The V-shaped structure consists of a pair of exhaust perforated plates with an included angle of 15° to 45°, a porosity of 10% to 30%, and an opening diameter of 3mm to 8mm.

[0069] In actual use: The control unit 18 controls the drive unit according to the usage mode. The drive unit drives the guide plate 17 to swing left and right. Since the pair of exhaust vent plates 16 have a V-shaped structure, the guide plate 17 can cover the left or right exhaust vent plate 16 when it swings left and right, so that some of the holes of the exhaust vent plate 16 are covered, thereby increasing the exhaust volume of the other exhaust vent plate 16.

[0070] The angle between the pair of exhaust orifice plates 16 is adapted to the angle when the guide plate 17 deflects, to prevent the surface of the guide plate 17 from failing to cover the exhaust orifice plates 16.

[0071] Example 5:

[0072] Reference Figure 2 The difference in this embodiment is that the area of ​​the guide plate 17 is at least greater than or equal to 50% of the area of ​​the exhaust orifice plate 16, the height or width of the guide plate 17 can be selected as 1 / 2 to 2 / 3 of the height or width of the exhaust orifice plate 16, and the initial angle of the guide plate 17 is 1 / 4 to 1 / 2 of the included angle between a pair of V-shaped combined exhaust orifice plates 16.

[0073] In actual use: When the guide plate 17 covers the exhaust plate 16, some of the holes in the exhaust plate 16 on this side can still be used for ventilation, thereby maintaining airflow in the actual storage area and preventing the volatile reagents from escaping.

[0074] During mode switching, in operating mode, the exhaust volume ratio between the inspection chamber 13 and the solvent storage area is 2:1, the organic solvent capture efficiency of the inspection chamber is 90%, and the capture efficiency of the solvent storage area is 85%. In this mode, priority is given to ensuring the solvent control effect of the inspection chamber 13. In normal mode, the exhaust volume ratio between the inspection chamber 13 and the solvent storage area is 1:2, the organic solvent capture efficiency of the inspection chamber is 85%, and the capture efficiency of the solvent storage area is 90%. In this mode, priority is given to ensuring the solvent control effect of the solvent storage area.

[0075] Example 6:

[0076] Reference Figure 2 The difference in this embodiment is that the driving unit consists of a pair of electric push rods 19. The tail ends of the pair of electric push rods 19 are respectively hinged to the opposite surfaces of a pair of exhaust vent plates 16, and the front ends of the pair of electric push rods 19 are respectively hinged to the two sides of the guide plate 17. Each exhaust vent plate 16 has a placement groove 20. The tail ends of the electric push rods 19 are hinged in the placement grooves, and the depth of the placement groove 20 is greater than the diameter of the electric push rod 19. The length of the placement groove 20 is greater than the total length of the electric push rod 19 when the front end is not extended. The electric push rod 19 is electrically connected to the control unit.

[0077] In actual use: when the push rods of the pair of electric push rods 19 are activated, for example, the push rod of the left electric push rod 19 extends and the push rod of the right electric push rod 19 retracts, causing the guide plate 17 to move to the right, and vice versa, to move to the left, thereby realizing the left and right swing control of the guide plate 17.

[0078] The placement slot 20 allows the electric push rod 19 on the side covered by the guide plate 17 to enter, thereby allowing the guide plate 17 to fit against the exhaust port plate 16.

[0079] Example 7:

[0080] Reference Figure 2 The difference in this embodiment is that a slide plate 21 is slidably connected to the rear side of the guide plate 17, and the front ends of a pair of electric push rods 19 are respectively hinged to the two sides of the slide plate 21.

[0081] In actual use: The slide plate 21 is pushed by a pair of electric push rods 19 at the same time, which can extend the slide plate 21 out of the guide plate 17, thereby increasing the coverage area of ​​the guide plate 17 on the exhaust hole plate 16. During operation, the push rods of the pair of electric push rods 19 are pushed out at the same time, which drives the slide plate 21 to extend. The extended slide plate 21, together with the guide plate 17, can achieve 100% coverage of the exhaust hole plate 16.

[0082] Example 8:

[0083] Reference Figure 2The difference in this embodiment is that: a rotating shaft 22 is detachably connected between a pair of exhaust orifice plates 16, the guide plate 17 is hinged on the rotating shaft 22, and an indicator 23 is detachably connected to the top of the rotating shaft 22 through the upper plate 10. The indicator 23 is used to provide real-time feedback on the rotation angle of the guide plate 17.

[0084] In actual use: the indicator 23 is rotated by the rotating shaft 22, so that the staff can intuitively observe the position of the exhaust plate 16 and thus determine whether the mode conversion of the control unit is successful.

[0085] Example 9:

[0086] Reference Figure 1-2 The difference in this embodiment is that a human body sensor 24 is detachably connected to the front surface of the vertical plate 1. The human body sensor 24 is located between the left side plate 9 and the exhaust section. The human body sensor 24 is electrically connected to the control unit 18.

[0087] In actual use: The human body sensor 24 can identify whether there are staff members in front of the inspection cavity 13, and then work with the control unit to realize automated preset control, so that the guide plate 17 moves to the position of the guide plate 17 in this mode, thus eliminating the need for repeated manual adjustment and control, and realizing non-contact signal feedback control.

[0088] Example 10:

[0089] Reference Figure 1-4 A method for controlling an optical inspection stage with efficient solvent control via micro-exhaust ventilation, comprising at least the aforementioned optical inspection stage with efficient solvent control via micro-exhaust ventilation, and further comprising the following steps:

[0090] Place the inspection table on the workbench;

[0091] Connect the negative pressure system 7 to the exhaust vent 6, and simultaneously connect the control unit 18 to the negative pressure system 7 and the external power supply respectively;

[0092] During operation, slide the light shield 12 upward to fully expose the visual inspection chamber 13. The presence of personnel is detected by the human body sensor 24, which feeds back an electrical signal to the control unit 18. The control unit 18 then activates the negative pressure system 7. The organic solvent passes through the visual inspection chamber 13, then through the exhaust plate 16, and finally through the exhaust port 6 and is drawn out by the negative pressure system 7.

[0093] At the same time, the control unit 18 controls a pair of electric push rods 19 to work together, thereby causing the guide plate 17 to deflect to the right, so that the exhaust plate 16 located on the right side of the guide plate 17 is partially covered, improving the exhaust efficiency of the inspection chamber 13, while retaining the exhaust effect on the shelf 4, thus realizing the air volume distribution by controlling the guide plate 17 through the electric push rods 19.

[0094] When reagent spillage occurs in front of the inspection chamber 13 or in or in front of the reagent storage area, the control unit 18 controls a pair of electric push rods 19 to work together. The push rods of the electric push rods 19 are pushed out simultaneously, causing the slide plate 21 to slide on the guide plate 17, increasing the area of ​​the slide plate 21. After the slide plate 21 slides out, the electric push rod 19 near the reagent spillage continues to push out, so that the guide plate 17 and the slide plate 21 completely cover the exhaust plate 16 on the other side, so that the exhaust plate 16 on this side can obtain the full power of the exhaust volume under the action of the negative pressure system 7, thereby achieving the maximum flow rate of exhaust in front of the inspection chamber 13 and in or in front of the reagent storage area.

[0095] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention 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 invention, and all such changes are within the protection scope of the technology.
