Description

Technical Field

[0001] The present invention relates to the technical field of lens production, and particularly relates to a lens dispensing and pressure maintaining device and method. Background Art

[0002] The installation method of lenses in electronic products is basically manual operation, that is, first fix the lens barrel manually, then dispense glue through a glue dispenser, then manually place the lens on the lens barrel, and then place the assembled product on a dedicated pressure maintaining device. However, the reliability of manual lens assembly is relatively low. Due to the characteristics of the adhesive itself, it is necessary to install the lens and perform pressure maintaining for a certain period of time within a specific time. Otherwise, it will affect the structural reliability of the product, and it is difficult for manual operation to ensure time and timeliness.

[0003] After the lens is dispensed with glue, if the lens cannot be installed in time by personnel, the bonding performance of the adhesive will gradually fail, thus affecting the quality of the product. After the lens is manually installed, if pressure maintaining is not carried out in time, the adhesive gradually fails, and the structural stability of the product decreases. Due to the high installation accuracy requirements of the lens, it is difficult for manual operation to ensure the positioning accuracy. Summary of the Invention

A pressure sensor is installed at the top end of the inner wall of the fifth slot. A spring telescopic rod is installed at the top of the sliding block. One end of the spring telescopic rod close to the pressure sensor abuts against the pressure sensor.

[0012] Preferably, an air inlet groove is opened above the inside of the auxiliary block.

The bottom of the second support rod is connected to the output end of the rotating motor.

[0014] Preferably, the lens picking mechanism includes an electric telescopic rod and a lens picking block. An electric telescopic rod is movably installed on one side of the second support rod facing the workbench. The telescopic end of the electric telescopic rod is away from the second support rod. The telescopic end of the electric telescopic rod is installed with a lens picking block. An electric suction cup is provided at the bottom of the lens picking block. Cameras are installed on both sides of the lens picking block. A lifting sliding groove is opened on one side of the second support rod facing the workbench. The installation end of the electric telescopic rod is connected with a lifting electric slider. The lifting electric slider is slidably installed inside the lifting sliding groove.

[0015] A lens dispensing and pressure-holding method, which is applicable to the above-mentioned dispensing and pressure-holding equipment, and this method further includes the following steps:

[0016] Step 1: Place the lens barrel on the top of the positioning block. The clamping plate clamps the outside of the lens barrel to complete the fixation of the lens barrel. The positioning block drives the lens barrel to move into the third slot. Start the negative ion blower to blow and remove dust from the position where dispensing is required on the top of the lens barrel.

[0017] Step 2: The fixing block moves below the dispensing head. The dispensing head dispenses glue on the lens barrel on the positioning block. When the fixing block moves to the second support rod, the suction cup at the bottom of the lens picking block adsorbs the lens and moves above the lens barrel, places the lens at a preset position above the lens barrel. The positioning block drives the lens barrel to move into the interior of the third slot, and the pressure maintaining block squeezes the top of the lens by the upward movement of the positioning block;

[0018] Step 3: After the lens reaches the preset pressure maintaining time, the bottom of the movable block moves out of the outer side of the bottom of the fourth slot. The positioning block drives the top of the lens to abut against the bottom of the sliding block. The sliding block slides into the interior of the fifth slot. The sliding block squeezes the spring telescopic rod, and the spring telescopic rod squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system for comparison;

[0019] Step 4: The airbag body inside the auxiliary slot is activated. The inner ring of the airbag body unfolds and abuts against the outer wall of the lens barrel. The negative ion blower is activated to blow air into the interior of the third slot. The air pressure value is detected by the air pressure sensor. After the air pressure value reaches the preset pressure value, the solenoid valve at the connection between the opening on the top of the auxiliary block and the conduit is closed. Within the preset interval, the change of the air pressure value inside the third slot is monitored;

[0020] Step 5: Through the two blanking manipulators arranged on the outside of the device, the lens barrels are classified and blanked according to the detection results of the above steps.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In the present invention, by setting a dispensing head, a lens picking block and a pressure maintaining block, after the positioning block completes the fixation of the lens barrel and moves below the dispensing head, the dispensing head completes the dispensing of the lens barrel. The lens barrel after dispensing moves below the lens picking block. The lens picking block can adjust the installation angle of the lens according to the actual installation situation. After the lens is installed, through the abutment of the pressure maintaining block and the lens, the pressure maintaining work of the lens can be realized, thereby realizing the precise automation of the lens installation work and increasing the accuracy of the installation of the lens and the lens barrel.

[0023] In the present invention, by setting a movable block, after the lens reaches the preset pressure maintaining time, the bottom of the movable block moves out of the outer side of the bottom of the fourth slot. The top of the lens abuts against the bottom of the sliding block. The sliding block slides into the interior of the fifth slot. The sliding block squeezes the spring telescopic rod, and the spring telescopic rod squeezes the pressure sensor. The pressure sensor transmits the measured pressure value to the background control system for comparison. If the difference between the pressure values measured by multiple pressure sensors exceeds the preset pressure value change range, it indicates that the lens is not installed flatly. Through this operation method, the flatness detection after the lens installation and pressure maintaining can be realized.

[0024] In the present invention, by providing an auxiliary groove and an air outlet, when the lens barrel on the positioning block moves into the third slot, the negative ion blower is started, and the gas in the air inlet groove is blown out through the air outlet and flows downward to the lower part of the third slot, so as to blow air at the position where glue needs to be applied on the top of the lens barrel. Through the blowing of the air flow, the position where glue needs to be applied on the top of the lens barrel can be cleaned by blowing, preventing the existence of floating dust at the position where glue needs to be applied on the top of the lens barrel and affecting the glue application effect of the device;

[0025] The airbag body inside the auxiliary groove is activated, and the airbag body abuts against the outer wall of the lens barrel. The negative ion blower is started to blow air into the third slot. The air pressure value is detected by the air pressure sensor. When the air pressure value reaches the preset pressure value, the electromagnetic valve at the connection between the opening on the top of the auxiliary block and the conduit is closed, so as to form a constant preset air pressure value inside the third slot. Subsequently, within a preset interval, the change of the air pressure value inside the third slot is monitored. Since the airbag body cannot completely seal the lens barrel, when the staff debug the device, the standard leakage value of the air pressure in the airtightness detection link will be measured. When detecting the production of the lens barrel and lens, only the air pressure value inside the third slot needs to be detected within a preset time and compared with the standard air pressure leakage value. If the air pressure change exceeds the standard air pressure leakage value, it means that the airtightness between the lens and the lens barrel does not meet the standard. Through this operation method, the airtightness detection after the installation of the lens and the lens barrel can be completed;

[0026] After the lens barrel and the lens in the fixed block are detected, the qualified lens barrels are clamped and unloaded by the qualified product blanking manipulator, and the unqualified lens barrels are clamped and unloaded by the defective product blanking manipulator, which is convenient for the staff to conduct secondary detection. Through this operation method, the classification blanking of qualified and unqualified lens barrels can be realized. BRIEF DESCRIPTION OF THE DRAWINGS

A clamping electric slider 21 is slidably installed inside the clamping chute 20. The top of the clamping electric slider 21 is installed with a clamping plate 19. By the way that the clamping electric slider 21 slides in the clamping chute 20, the clamping plate 19 clamps on the outside of the lens barrel to complete the fixing of the lens barrel.

[0045] As a technical optimization scheme of the present invention, a moving chute 16 is opened at the bottom end of the inner wall of the second slot 13. A moving electric slider 17 is connected to the bottom of the positioning block 15 near the moving chute 16. The moving electric slider 17 is slidably installed inside the moving chute 16. The bottom of the positioning block 15 is embedded with an electric lifting rod 18. The installation end of the electric lifting rod 18 faces downward, and the installation end of the electric lifting rod 18 is connected to the top of the moving electric slider 17. By the sliding of the moving electric slider 17 in the moving chute 16, the positioning block 15 can slide inside the second slot 13 according to different usage requirements, and the electric lifting rod 18 can drive the positioning block 15 to lift.

[0046] As a technical optimization scheme of the present invention, the pressure maintaining mechanism includes an auxiliary block 14 and a pressure maintaining block 23. The fixing block 4 installs an auxiliary block 14 on one side of the top of the second slot 13. A third slot 22 is opened at the bottom of the auxiliary block 14. The top end of the inner wall of the third slot 22 is installed with a pressure maintaining block 23. A rubber pad is provided at the bottom of the pressure maintaining block 23. The pressure maintaining block 23 abuts above the lens and the lens barrel, and can realize the pressure maintaining work after the installation of the lens.

[0047] As a technical optimization solution of the present invention, a plurality of fourth slots 28 are evenly opened at the bottom of the pressure-holding block 23. An activity block 29 is slidably installed inside the fourth slot 28. An electric extension rod 30 is installed between the top of the activity block 29 and the top end of the inner wall of the fourth slot 28. A detection mechanism is provided on the activity block 29. The activity block 29 is driven by the electric extension rod 30 to move inside the fourth slot 28, so that the detection mechanism on the activity block 29 will not interfere with the function of the pressure-holding block 23 when not in use.

[0048] As a technical optimization solution of the present invention, the detection mechanism includes a sliding block 32 and a pressure sensor 33. A fifth slot 31 is opened at the bottom of the activity block 29. The sliding block 32 is slidably installed inside the fifth slot 31. Positioning sliding grooves 35 are opened on both inner walls of the fifth slot 31. A positioning sliding block 36 is installed on one side of the sliding block 32 close to the positioning sliding groove 35. The positioning sliding block 36 is slidably installed inside the positioning sliding groove 35. The pressure sensor 33 is installed at the top end of the inner wall of the fifth slot 31. A spring telescopic rod 34 is installed at the top of the sliding block 32. One end of the spring telescopic rod 34 close to the pressure sensor 33 abuts against the pressure sensor 33.

The top of the lens abuts against the bottom of the sliding block 32. The sliding block 32 slides into the fifth slot 31. The sliding block 32 squeezes the spring telescopic rod 34. The spring telescopic rod 34 squeezes the pressure sensor 33. The pressure sensor 33 transmits the measured pressure value to the background control system for comparison. If the difference in the pressure values measured by multiple pressure sensors 33 exceeds the preset pressure value change range, it means that the lens is not installed flat. Through this operation method, the flatness of the lens after pressure-holding installation can be detected.

[0049] As a technical optimization solution of the present invention, an air inlet groove 27 is provided above the interior of the auxiliary block 14. A plurality of air outlet holes 26 are evenly penetrated through the inner wall of the third slot 22 at the location where the air inlet groove 27 is provided. A pressure sensor 25 is embedded and installed on the inner wall inside the third slot 22. An auxiliary groove 24 is provided at the lower position of the inner wall of the third slot 22, and an airbag body 39 is provided inside the auxiliary groove 24. The airbag body 39 inside the auxiliary groove 24 is activated, the inner ring of the airbag body 39 extends and abuts against the outer wall of the lens barrel. The negative ion blower is activated to blow air into the inside of the third slot 22. The pressure value is detected by the pressure sensor 25. When the pressure value reaches the preset pressure value, the electromagnetic valve at the connection between the hole at the top of the auxiliary block 14 and the conduit is closed, so that a constant pressure value is formed inside the third slot 22. The pressure value inside the third slot 22 is detected within a preset time and compared with the standard air pressure leakage value. If the air pressure change exceeds the standard air pressure leakage value, it indicates that the airtightness between the lens and the lens barrel does not meet the standard. By this operation method, the airtightness detection after the installation of the lens and the lens barrel can be completed.

[0050] As a technical optimization solution of the present invention, an installation block 37 is installed on the same side of the workbench 1 where the first support rod 5 is installed. A rotating motor 38 is embedded and installed at the top of the installation block 37. The output end of the rotating motor 38 faces upward, and the bottom of the second support rod 8 is connected to the output end of the rotating motor 38.

Combining the movement of the electric telescopic rod 11 on the second support rod 8 and the telescopic movement of the electric telescopic rod 11 driving the lens picking block 12, and cooperating with the use of the camera, the electric suction cup below the lens picking block 12 can be adjusted in angle when sucking the lens, and can also be adjusted in angle according to the specific situation when the lens and the lens barrel are installed, so that the installation of the lens and the lens barrel is more accurate.

[0051] As a technical optimization solution of the present invention, the lens picking mechanism includes an electric telescopic rod 11 and a lens picking block 12. The electric telescopic rod 11 is movably installed on the side of the second support rod 8 facing the workbench 1.

By the sliding of the lifting electric slider 10 in the lifting sliding groove 9, the electric telescopic rod 11 can move on the second support rod 8.

[0052] A method for dispensing and pressure maintaining of a lens, this dispensing and pressure maintaining method is applicable to the above-mentioned dispensing and pressure maintaining equipment, and this method further includes the following steps:

[0053] Step 1: Place the lens barrel on the top of the positioning block 15, and clamp the lens barrel with the clamping plate 19 on the outside to complete the fixation of the lens barrel. The positioning block 15 drives the lens barrel to move into the third slot 22, and start the negative ion blower to blow air and remove dust from the position where glue needs to be applied on the top of the lens barrel.

[0054] Step 2: The fixing block 4 moves below the dispensing head 7, and the dispensing head 7 dispenses glue on the lens barrel on the positioning block 15. When the fixing block 4 moves to the second support rod 8, the suction cup at the bottom of the lens taking block 12 adsorbs the lens and moves above the lens barrel, and places the lens at the preset position above the lens barrel. The positioning block 15 drives the lens barrel to move into the third slot 22, and the pressure maintaining block 23 squeezes the top of the lens by moving the positioning block 15 upward.

[0055] Step 3: After the lens reaches the preset pressure maintaining time, the bottom of the movable block 29 moves out of the bottom outside of the fourth slot 28, and the positioning block 15 drives the top of the lens to abut against the bottom of the sliding block 32. The sliding block 32 slides into the fifth slot 31, the sliding block 32 squeezes the spring telescopic rod 34, the spring telescopic rod 34 squeezes the pressure sensor 33, and the pressure sensor 33 transmits the measured pressure value to the background control system for comparison.

[0056] Step 4: The airbag body 39 inside the auxiliary slot 24 is activated. The inner ring of the airbag body 39 unfolds and abuts against the outer wall of the lens barrel. The negative ion blower is started to blow air into the third slot 22, and the air pressure value is detected by the air pressure sensor 25. After the air pressure value reaches the preset pressure value, the solenoid valve at the connection between the opening on the top of the auxiliary block 14 and the conduit is closed, and within the preset interval, the change of the air pressure value inside the third slot 22 is monitored.

[0057] Step 5: Through the two blanking manipulators arranged on the outside of the device, the lens barrels are classified and blanked according to the detection results of the above steps.

[0058] When the present invention is in use, the device is applicable to the production of lenses for large electronic products such as digital cameras. The electrical equipment used in this device is all powered by connecting to an external power supply through wires. In this device, the electrical equipment in the device is controlled by setting a control system. The air pressure sensor 25, pressure sensor 33, electric suction cup and dispensing head 7 used in this device are all existing mature technologies, so no more elaboration will be made on them. The airbag body 39 embedded and installed in the auxiliary slot 24 is an electric device and is an existing mature technology, so no more elaboration will be made on it. The top of the auxiliary block 14 is provided with a negative ion blower, and the air outlet of the negative ion blower is connected to the opening on the top of the auxiliary block 14 through a conduit. The opening on the top of the auxiliary block 14 is connected to the air inlet slot 27, and a solenoid valve is provided at the connection between the opening on the top of the auxiliary block 14 and the conduit.

[0059] When the lens barrel and the lens need to be installed, the conveyor belt 3 starts, and the conveyor belt 3 drives the fixed block 4 to operate in the manner from right to left as shown Figure 1 In the shown device state, the right side is the feeding side. By sliding the moving electric slider 17 in the moving chute 16, the positioning block 15 slides inside the second slot 13. When the positioning block 15 moves to the preset position and is not below the auxiliary block 14 at this time, then the positioning block 15 is driven upward by the electric lifting rod 18 to the preset use height position. The staff places the lens barrel on the top of the positioning block 15 with the part to be glued on the lens barrel facing upward. By sliding the clamping electric slider 21 in the clamping chute 20, the clamping plate 19 clamps on the outside of the lens barrel to complete the fixation of the lens barrel. The position where the clamping plate 19 clamps the lens barrel is the outer part at the bottom of the lens barrel, and the top height of the lens barrel is higher than the top height of the clamping plate 19; Figure 1 After the clamping and fixation of the lens barrel are completed, the positioning block 15 moves downward to the preset use position, and then the positioning block 15 moves to the use position below the auxiliary block 14. The positioning block 15 moves upward until the lens barrel on the positioning block 15 moves into the third slot 22. The negative ion blower is started, and the gas in the air inlet groove 27 is blown out through the air outlet hole 26 and flows downward to the third slot 22, so that the position on the top of the lens barrel that needs to be glued can be blown. Through the blowing of the air flow, the position on the top of the lens barrel that needs to be glued can be blown and cleaned to prevent the existence of floating dust at the position on the top of the lens barrel that needs to be glued, which affects the gluing effect of the device;

[0060] After the blowing and dust removal of the lens barrel are completed, the positioning block 15 moves again to the preset use position in the second slot 13. Driven by the conveyor belt 3, the fixed block 4 moves below the dispensing head 7. Then the conveyor belt 3 stops operating, and the dispensing head 7 dispenses glue on the lens barrel on the positioning block 15. After the dispensing is completed, the conveyor belt 3 drives the fixed block 4 to move again. When the fixed block 4 moves to the second support rod 8, the conveyor belt 3 stops operating. The suction cup at the bottom of the lens picking block 12 adsorbs the lens and moves above the lens barrel. Then the lens picking block 12 places the lens at the preset position above the lens barrel, and the suction cup is separated from the lens. At the same time, the positioning block 15 drives the lens barrel to move into the third slot 22, and the pressing block 23 presses the top of the lens by moving the positioning block 15 upward. Through this operation method, the pressure maintaining work after the installation of the lens and the lens barrel is realized;

[0061] After the blowing and dust removal of the lens barrel are completed, the positioning block 15 moves again to the preset use position in the second slot 13. Driven by the conveyor belt 3, the fixed block 4 moves below the dispensing head 7. Then the conveyor belt 3 stops operating, and the dispensing head 7 dispenses glue on the lens barrel on the positioning block 15. After the dispensing is completed, the conveyor belt 3 drives the fixed block 4 to move again. When the fixed block 4 moves to the second support rod 8, the conveyor belt 3 stops operating. The suction cup at the bottom of the lens picking block 12 adsorbs the lens and moves above the lens barrel. Then the lens picking block 12 places the lens at the preset position above the lens barrel, and the suction cup is separated from the lens. At the same time, the positioning block 15 drives the lens barrel to move into the third slot 22, and the pressing block 23 presses the top of the lens by moving the positioning block 15 upward. Through this operation method, the pressure maintaining work after the installation of the lens and the lens barrel is realized;

[0062] The way for the lens picking block 12 to pick up the lens is as follows: place the workpiece storing the lens at the position on the top of the workbench 1 where the second support rod 8 is located. The movement trajectory of the lens picking block 12 is supported by the shooting of the camera. Subsequently, the electric telescopic rod 11 drives the lens picking block 12 to expand and contract, combined with the lifting electric slider 10 sliding up and down in the lifting chute 9 and the rotation motor 38 driving the second support rod 8 to rotate, so that the electric suction cup at the bottom of the lens picking block 12 can move above the lens to be picked up. Combining with the suction of the electric suction cup, the picking and placing of the lens can be completed.

[0063] After the lens reaches the preset pressure holding time, the positioning block 15 moves downward, so that the bottom of the pressure holding block 23 no longer abuts against the top of the lens. Subsequently, the electric extension rod 30 drives the movable block 29 to move downward, so that the bottom of the movable block 29 moves out of the outside of the bottom of the fourth slot 28. At this time, the positioning block 15 moves upward again, and the top of the lens abuts against the bottom of the sliding block 32. The sliding block 32 slides into the fifth slot 31. The sliding block 32 squeezes the spring telescopic rod 34, and the spring telescopic rod 34 squeezes the pressure sensor 33. The pressure sensor 33 transmits the measured pressure value to the background control system for comparison. If the difference in the pressure values measured by multiple pressure sensors 33 exceeds the preset pressure value change range, it means that the lens is not installed flatly. Through this operation method, the flatness detection of the lens after installation and pressure holding can be realized.

[0064] The positioning block 15 drives the lens barrel to move up and down inside the third slot 22, so that the lens barrel with the lens installed moves to the preset use height position. At this time, the horizontal height of the installation part of the lens and the lens barrel is above the horizontal position of the top of the auxiliary slot 24, and the rest of the lens barrel is below the horizontal height of the bottom of the auxiliary slot 24. The airbag body 39 inside the auxiliary slot 24 is started, and the inner ring of the airbag body 39 extends and abuts against the outer wall of the lens barrel. The negative ion blower is started to blow air into the third slot 22. The air pressure sensor 25 detects the air pressure value. When the air pressure value reaches the preset pressure value, the electromagnetic valve at the connection between the opening on the top of the auxiliary block 14 and the conduit is closed, so that a constant preset air pressure value is formed inside the third slot 22. Subsequently, within the preset interval, the change of the air pressure value inside the third slot 22 is monitored. Since the airbag body 39 cannot absolutely seal the lens barrel, when the staff adjusts the device, the standard leakage value of the air pressure in the airtightness detection link will be measured. When detecting the production of the lens barrel and lens, only the air pressure value inside the third slot 22 needs to be detected within the preset time and compared with the standard air pressure leakage value. If the air pressure change exceeds the standard air pressure leakage value, it means that the airtightness between the lens and the lens barrel does not meet the standard. Through this operation method, the airtightness detection of the lens and the lens barrel after installation can be completed.

[0065] There are two blanking manipulators arranged on the outer side of the workbench 1 far away from the first support rod 5 and the second support rod 8. One of them is a qualified product blanking manipulator and the other is a defective product blanking manipulator. After the lens barrel and the lens in the fixing block 4 are detected, the qualified lens barrels are clamped and blanked by the qualified product blanking manipulator, and the unqualified lens barrels are clamped and blanked by the defective product blanking manipulator, which is convenient for the staff to conduct secondary detection. Through this operation method, the classified blanking of qualified and unqualified lens barrels can be realized.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
