Description

Technical Field

[0001] The invention relates to the field of optical detection, and in particular to an optical inspection platform with micro-exhaust and efficient solvent control and a control method thereof. Background Art

[0002] When visually inspecting optical lenses manually, it is necessary to use a cotton swab dipped in organic solvents such as ether, ethanol, and acetone to clean the lens surface. The cotton swab and solvent are left open on the table, and the organic solvents continue to evaporate into the air. These organic solvents not only irritate the eyes and respiratory system of the operators, causing damage to the central nervous system, but also increase the risk of explosion when they accumulate in the workplace. Due to the process cleanliness requirements, axial flow fans cannot be installed on the outer walls of the optical lens inspection site for ventilation.

[0003] The existing optical inspection table only has the function of manual visual inspection, and no organic solvent collection device is installed. If a local exhaust hood is installed on the side or above the inspection table, the exhaust hood is often far away for the purpose of not interfering with the inspection process, and it is impossible to quickly collect organic solvents at the beginning of their generation, resulting in poor solvent control effect. When designing the air volume, the air conditioning system of the clean workshop only considers the fresh air volume for personnel, and does not consider the air volume required to exhaust organic solvents, resulting in insufficient ventilation times of the air conditioning system during actual operation. If only relying on the daily air conditioning system for full-room dilution and exhaust, the concentration of organic solvents will be limited and the expected control effect cannot be achieved. If the exhaust volume of the daily air conditioning system is increased, the cold and hot balance of the clean workshop air will be destroyed, and the air supply volume of the air conditioning system needs to be increased simultaneously, resulting in a significant increase in the operating load of the air conditioning system, an increase in the power consumption of the workshop, and an increase in the operating costs of the enterprise.

[0004] Therefore, it is necessary to propose a new small-volume solvent zoning intelligent control technology to efficiently control the disorderly diffusion of organic solvents in optical lens inspection sites. Summary of the invention

[0007] Furthermore, a partition is vertically fixed between the left side plate and the exhaust part, a drawer is slidably connected between the partition and the bottom plate, and the upper surface of the partition is covered with an anti-reflective coating.

[0008] Furthermore, the exhaust part is composed of a pair of exhaust hole plates, a driving part, and a guide plate. The front sides of the pair of exhaust hole plates are fixedly connected to each other, the rear sides of the pair of exhaust hole plates are fixed to the front surface of the vertical plate, the pair of exhaust hole plates form a V-shaped structure, the top ends of the pair of exhaust hole plates are vertically fixed to the lower surface of the upper plate, the lower ends of the pair of exhaust hole 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 hole plates, the driving part is detachably connected between the pair of exhaust hole plates, the driving end of the driving part is hinged to the guide plate, the exhaust port is located between the pair of exhaust hole plates, the driving part is electrically connected to the control unit, and one of the exhaust hole plates is located on the side of the left plate covered with an anti-reflective coating.

[0013] 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 part, and the human body sensor is electrically connected to the control unit.

[0014] A control method for an optical inspection table with micro-exhaust and efficient solvent control includes at least the above-mentioned optical inspection table with micro-exhaust and efficient solvent control, and is characterized in that it also includes the following steps: Place the inspection table on the workbench; Connect the negative pressure system to the exhaust port, and electrically connect the negative pressure system and the external power supply through the control unit; During operation, slide the visor upward to fully expose the visual inspection cavity. The human body sensor senses the presence of a worker, and the human body sensor feeds back an electrical signal to the control unit. The control unit starts the negative pressure system, and the organic solvent passes through the visual inspection cavity, then passes through the exhaust hole plate, and then is sucked out by the negative pressure system through the exhaust port. At the same time, the control unit controls a pair of electric push rods to move together, thereby deflecting the guide plate to the right, so that the exhaust hole plate on the right side of the guide plate is partially covered, thereby improving the exhaust efficiency of the visual inspection chamber, while retaining the exhaust effect of the storage plate position; When reagent spills in front of the visual inspection chamber and in or in front of the reagent storage area, a pair of electric push rods are controlled by the control unit to move jointly, and the push rods of the electric push rods are pushed out at the same time to make the slide plate slide on the guide plate to increase the area of ​​the slide plate. After the slide plate slides out, the electric push rod close to the reagent spillage continues to push the push rod so that the guide plate and the slide plate completely cover the exhaust orifice plate on the other side, so that the exhaust orifice plate on this side can obtain the full-power exhaust volume under the action of the negative pressure system, thereby obtaining the maximum flow exhaust effect in front of the visual inspection chamber and in or in front of the reagent storage area.

[0015] The beneficial effect of the present invention is that: due to the use of an anti-reflective layer, the problem of uneven lighting caused by reflection of light in the visual inspection cavity when the inspection light source is illuminated is effectively solved, thereby achieving that the light of the inspection light source will not be affected by reflection after entering the visual inspection cavity, thereby preventing the problem of uneven lighting caused by light passing through the visual inspection cavity to irradiate outward.

[0016] Since a pair of exhaust orifice plates are adopted, and the pair of exhaust orifice plates are combined in a V-shaped structure, the problem of exhausting the visual inspection chamber and the reagent storage area at the same time is effectively solved. By controlling the guide plate to partially cover one of the exhaust orifice plates, the air volume of the visual inspection chamber and the reagent storage area can be zoned. At the same time, this side retains less exhaust effect, achieving a reasonable distribution effect.

[0017] Due to the use of a human body sensor, automatic control is effectively realized. The human body sensor can identify whether there is a staff member operating in front of the visual inspection chamber, and then cooperate with the control unit to realize automatic preset control and move the guide plate to the position of this mode.

[0018] The use of the slide plate effectively solves the problem that the air volume cannot be increased when the reagent is poured, thereby achieving full coverage of the exhaust hole plate on the other side, thereby increasing the exhaust volume on this side and reducing the escape of volatile gases.

[0019] Due to the use of the top plate and the storage plate, and the workbench placed on it, the reagent storage area forms a structure with a front opening, so that the flow trajectory during exhaust covers the reagent storage area, and the upper space can be utilized through the storage plate.

[0020] Due to the use of a control unit, the control unit can preset the mode, which is divided into normal mode, working mode and emergency mode. In the normal mode, the reagent storage area is the main exhaust area, in the working mode, the visual inspection chamber is the main exhaust area, and in the emergency mode, the guide plate can be controlled to fully cover the exhaust hole plate on one side.

DETAILED DESCRIPTION

[0027] Embodiment 1: Reference Figure 1-4 , is a schematic diagram of the structure of Example 1 of the present invention, an optical inspection table with micro-exhaust and efficient solvent control, including a negative pressure system 7, including: Vertical board 1; An inspection chamber 2, the inspection chamber 2 is fixed to the left side of the front surface of the vertical plate 1, and the inspection chamber 2 is covered with an anti-reflective layer; A top plate 3, wherein 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 located on the same horizontal plane; The storage plate 4 is fixed to the right side of the front surface of the vertical plate 1, and the storage plate 4 is located below the top plate 3. The top plate 3 and the storage plate 4 form a reagent storage area; The right side plate 5 is fixed to the right side of the vertical plate 1, the top plate 3 and the storage plate 4, and the top of the right side plate 5 is aligned with the lower surface of the right side of the top plate 3; An exhaust part, which is fixed between the inspection chamber 2 and the top plate 3 and the storage plate 4, and is connected to the inspection chamber 2; The exhaust port 6 is arranged on the vertical plate 1, and the exhaust port is connected with the exhaust part, and the negative pressure system 7 is connected with the exhaust port 6; An inspection light source 8, the inspection light source 8 is detachably connected to the upper surface of the inspection chamber 2, a light-transmitting hole is opened on the upper surface of the inspection chamber 2, and the inspection light source 8 is located on the light-transmitting hole; The control unit 18 is detachably connected to the vertical plate 1 and is located at the rear side of the inspection chamber 2. The control unit is electrically connected to the negative pressure system 7, the exhaust part and the inspection light source 8 respectively.

[0028] In actual use: the inspection table is placed on the desktop of the workbench. At this time, the bottom of the reagent storage area is covered by the workbench desktop, so that the reagent storage area forms a structure with an open front side. Tools and reagents are placed on the workbench desktop under the top plate 3 and on the storage plate 4, and optical inspection of the lens is performed in front of the inspection chamber 2.

[0029] The sub-control module of the workshop's negative pressure system 7 is electrically connected to the control unit 18, and the negative pressure system 7 is connected to the exhaust port 6 at the same time, so that the negative pressure system 7 is exhausted through the exhaust part, and the air in the inspection chamber and in front of the reagent storage area enters the exhaust part, and then enters the negative pressure system 7 through the exhaust port 6.

[0030] When the exhaust part is working, 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 inspection chamber, otherwise it is the working mode. In the emergency mode, the reagent storage area or the inspection chamber 2 is completely closed, so that the air enters completely through the reagent storage area or the inspection chamber 2, thereby instantly increasing the exhaust effect and reducing gas escape.

[0031] The anti-reflective layer can prevent the light from the inspection light source 8 from being reflected in the inspection chamber, thereby avoiding uneven light during optical inspection.

[0032] 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.

[0033] The anti-reflective layer can be black velvet or black paint, which mainly prevents the reflection of light.

[0034] Negative pressure system 7 exhaust volume is 100~500m 3 / h.

[0035] The solvent storage area is used to store organic solvents and cotton swabs used for inspection, such as ethyl acetate, acetone, ether, etc.

[0036] The inspection light source 8 adopts an explosion-proof lighting light source, which effectively reduces the safety risk of continuous emission of flammable and explosive organic solvents in the place and the accumulation of increased concentrations in a relatively closed space, causing combustion and explosion.

[0038] During actual use: the staff sits in front of the workbench and is in front of the visual inspection chamber 13, then opens the shading plate 12, and the shading plate 12 slides upward. According to the working habits of the staff, the shading plate 12 is controlled to slide to a suitable position and locked. At the same time, the control unit controls the inspection light source 8 to turn on and the exhaust part to work, so that the exhaust part is adjusted to the working mode, and the air in front of the visual inspection chamber 13 passes through the visual inspection chamber 13 into the exhaust part, completing the preparation before work.

[0039] 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 light is transmitted in front of the visual inspection cavity 13, which is convenient for the staff to perform optical inspection.

[0040] Embodiment 3: Reference Figure 1-3 The difference of this embodiment is that a partition 14 is vertically fixed between the left side plate 9 and the exhaust part, 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.

[0041] In actual use: the drawer 15 can be used for storage, thereby improving the utilization rate of the inspection table and making it convenient for the staff to take out the tools used in optical inspection, such as cotton swabs, organic solvent glass bottles and other small tools.

[0043] During actual use: the control unit 18 controls the driving unit according to the usage mode, and the driving unit drives the guide plate 17 to swing left and right. Since a pair of exhaust hole plates 16 are in a V-shaped structure, the guide plate 17 can cover the left exhaust hole plate 16 or the right exhaust hole plate 16 when swinging left and right, so that part of the holes of the exhaust hole plate 16 are covered, thereby increasing the exhaust volume of the exhaust hole plate 16 on the other side.

[0044] The angle between the pair of exhaust hole plates 16 matches the angle of the deflection of the guide plate 17 to prevent the guide plate 17 from failing to cover the exhaust hole plates 16 .

[0045] The angle of the pair of exhaust hole plates 16 of the V-shaped structure combination is 15-45 degrees, the porosity is 10%-30%, and the opening diameter is 3mm-8mm.

[0046] Embodiment 5: Reference Figure 2 The difference of 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 hole plate 16, and the height or width of the guide plate 13 can be selected to be 1 / 2 to 2 / 3 of the height or width of the exhaust hole plate 16. The initial angle of the guide plate 13 is 1 / 4 to 1 / 2 of the angle between the exhaust hole plates 16 in a pair of V-shaped combinations.

[0047] In actual use: when the guide plate 17 covers the exhaust hole plate 16, part of the holes of the exhaust hole plate 16 on this side can also be used for exhaust, thereby maintaining air flow in the actual storage area and preventing the volatile reagent from escaping.

[0048] When the mode is switched, in the working mode, the exhaust volume of the visual inspection chamber 13 and the solvent storage area is 2:1, the organic solvent capture efficiency of the visual inspection chamber is 90%, and the capture efficiency of the solvent storage area is 85%. At this time, the solvent control effect of the visual inspection chamber 13 is prioritized. In the normal mode, the exhaust volume of the visual inspection chamber 13 and the solvent storage area is 1:2, the organic solvent capture efficiency of the visual inspection chamber is 85%, and the capture efficiency of the solvent storage area is 90%. At this time, the solvent control effect of the solvent storage area is prioritized.

[0049] Embodiment 6: Reference Figure 2 The difference of this embodiment is that: the driving part is composed of a pair of electric push rods 19, the tail ends of the pair of electric push rods 19 are respectively hinged on the opposite surfaces of a pair of exhaust hole plates 16, the front ends of the pair of electric push rods 19 are respectively hinged to the two side surfaces of the guide plate 17, the exhaust hole plates 16 are all provided with placement grooves 20, the tail ends of the electric push rods 19 are hinged in the placement grooves, and the depth of the placement grooves 20 is greater than the diameter of the electric push rods 19, and the length of the placement grooves 20 is greater than the total length of the front end of the electric push rods 19 when they are not extended, and the electric push rods 19 are electrically connected to the control unit.

[0050] In actual use, when the push rods of the pair of electric push rods 19 are in motion, for example, the push rod of the left electric push rod 19 is extended, and the push rod of the right electric push rod 19 is retracted, the guide plate 17 moves to the right, and vice versa, moves to the left, thereby realizing left-right swing control of the guide plate 17.

[0051] The placement groove 20 allows the electric push rod 19 on the side covered by the guide plate 17 to enter, so that the guide plate 17 can be attached to the exhaust hole plate 16.

[0052] Embodiment 7: Reference Figure 2 The difference of 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 hinged to the two side surfaces of the slide plate 21 respectively.

[0053] In actual use: the skateboard 21 is pushed simultaneously by a pair of electric push rods 19, so that the skateboard 21 can be extended 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 a pair of electric push rods 19 are pushed out at the same time, driving the skateboard 21 to extend out. The extended skateboard 21 cooperates with the guide plate 17 to achieve 100% coverage of the exhaust hole plate 16.

[0054] Embodiment 8: Reference Figure 2The difference of this embodiment is that: a pair of the exhaust hole plates 16 are detachably connected with a rotating shaft 22, the guide plate 17 is hinged on the rotating shaft 22, and the top end of the rotating shaft 22 extends upward through the upper plate 10 and is detachably connected with an indicator 23, and the indicator 23 is used for real-time feedback of the rotation angle of the guide plate 17.

[0055] In actual use: the indicator 23 is driven to rotate by the rotating shaft 22, so that the staff can intuitively observe the position of the exhaust hole plate 16, thereby judging whether the mode conversion of the control unit is successful.

[0056] Embodiment 9: Reference Figure 1-2 The difference of this embodiment is that a human body sensor 24 is detachably connected to the front surface of the vertical plate 1 , and the human body sensor 24 is located between the left side plate 9 and the exhaust part, and the human body sensor 24 is electrically connected to the control unit 18 .

[0057] In actual use: the human body sensor 24 can be used to identify whether there is a staff member in front of the visual inspection chamber 13, and then cooperate with the control unit to realize automatic preset control, so that the guide plate 17 moves to the guide plate 17 position in this mode, thereby eliminating the need for manual repeated adjustment and control, and realizing non-contact signal feedback control.

[0058] Embodiment 10: Reference Figure 1-4 A control method for an optical inspection station with micro-exhaust and efficient solvent control includes at least the above-mentioned optical inspection station with micro-exhaust and efficient solvent control, and further includes the following steps: Place the inspection table on the workbench; Connect the negative pressure system 7 to the exhaust port 6, and electrically connect the negative pressure system 7 and the external power supply through the control unit 18; During operation, the shading plate 12 is slid upward to fully expose the visual inspection cavity 13. The human body sensor 24 senses the presence of a worker, and the human body sensor 24 feeds back an electrical signal to the control unit 18. The control unit 18 starts the negative pressure system 7, and the organic solvent passes through the visual inspection cavity 13, and then passes through the exhaust hole plate 16 and the exhaust port 6 to be sucked out by the negative pressure system 7; At the same time, the control unit 18 controls a pair of electric push rods 19 to move together, thereby deflecting the guide plate 17 to the right, so that the exhaust hole plate 16 located on the right side of the guide plate 17 is partially covered, thereby improving the exhaust efficiency of the visual inspection chamber 13, while retaining the exhaust effect of the position of the storage plate 4, thereby realizing the control of the guide plate 17 by the electric push rod 19 to distribute the air volume; When reagent spillage occurs in front of the visual inspection chamber 13 and in or in front of the reagent storage area, a pair of electric push rods 19 are controlled by the control unit 18 to jointly act, and the push rods of the electric push rods 19 are pushed out at the same time to make the slide plate 21 slide on the guide plate 17 to increase the area of ​​the slide plate 21. After the slide plate 21 slides out, the electric push rod 19 close to the reagent spillage continues to push the push rod so that the guide plate 17 and the slide plate 21 completely cover the exhaust orifice plate 16 on the other side, so that the exhaust orifice plate 16 on this side can obtain the full-power exhaust volume under the action of the negative pressure system 7, thereby obtaining the maximum flow exhaust effect in front of the visual inspection chamber 13 and in or in front of the reagent storage area.
