Description

Technical Field

[0001] This utility model relates to the field of image acquisition technology, specifically to a motor-driven QR code scanning device. Background Technology

[0002] During the actuator assembly and production process, the clamping and placement of the motor and wiring; the alignment and welding of the motor and wiring; the docking of the motor and worm gear; and the placement of the motor in the lower housing are all completed at one workstation.

[0003] Before aligning and soldering the motor and wiring, a scanner is needed to scan the motor's QR code and input the information to ensure that each motor installed in the actuator can be tracked.

[0004] The scanner currently in use is directly mounted on the platform, with the scanner's acquisition end facing the turntable that holds the motor. The scanner can start scanning when the turntable rotates the motor to the scanning position.

[0005] Since the scanner is directly exposed to the workstation environment, dust can obstruct the input of QR code information and affect the normal production cycle. In addition, the long continuous working time of the scanner can cause heat accumulation, which can affect the lifespan and operational stability of electronic components.

[0006] Therefore, in order to solve the above problems, a motor QR code scanning device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a motor-driven QR code scanning device that has heat dissipation and dust protection capabilities throughout the entire process of using the scanner, thereby solving the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A motor-driven QR code scanning device includes an isolation box, with one end open and the other end closed. A cylinder is fixedly installed at the closed end of the isolation box, and a scanner is fixedly installed on the cylinder's push rod. The scanner is located inside the isolation box. Isolation doors are hinged to the upper and lower sides of the open end of the isolation box via torsion shafts. The upper isolation door has a cavity, and an exhaust pipe communicating with the cavity is installed on the lower side of the upper isolation door. A ventilation mechanism is fixedly installed on the upper side of the isolation box, and the output end of the ventilation mechanism is connected to the cavity.

[0009] Specifically, the ventilation mechanism includes an air filter cartridge, an air pump, and a hose. The air pump is fixedly assembled with the isolation box. An air filter cartridge is installed at the input end of the air pump, and the output end of the air pump is connected to the cavity through a hose.

[0010] Specifically, the torsion shaft includes a torsion spring and a pin. The isolation box and the isolation door are hinged together by the pin. The pin is fitted with a torsion spring. One end of the torsion spring is fixedly assembled with the isolation box, and the other end of the torsion spring is fixedly assembled with the isolation door.

[0011] Furthermore, limit plates are fixedly installed on the opposite sides of the isolation doors, and when the isolation doors swing to the horizontal position, the limit plates abut against the outer sidewall of the isolation box.

[0012] Specifically, there are two exhaust pipes installed at an angle, and the output direction of the exhaust pipes is towards the acquisition end of the scanner.

[0013] Specifically, the scanner has rotating rollers mounted on both the upper and lower sides via roller frames, and the rotating rollers abut against the inner side wall or isolation door of the isolation box.

[0014] Specifically, the closed end of the isolation box is equipped with a one-way air valve and a temperature sensor.

[0015] Specifically, support feet are fixedly installed on the bottom of both the front and rear sides of the isolation box.

[0016] Compared with the prior art, the beneficial effects of this utility model are: When the scanner is in use, it can be pushed out of the isolation box by the cylinder and the isolation door is opened at the same time. The high-pressure air input into the cavity of the ventilation mechanism is finally discharged from the exhaust pipe, which can form an air curtain at the scanning end of the scanner. While having heat exchange capacity, it can also prevent dust and other debris from adhering to the scanning end of the scanner, and maintain the normal rhythm of QR code collection. When the scanner is not in operation, the isolation box and isolation door can form a sealed space, effectively preventing dust from entering and avoiding contamination of the scanner's acquisition end. In addition, the combination of the ventilation mechanism and temperature sensor can also maintain the scanner in a suitable temperature range, extending the life of electronic components.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example content: Please see Figure 1 A motor QR code scanning device is provided, including an isolation box 1, with one end of the isolation box 1 being open and the other end being closed. A cylinder 10 is fixedly installed at the closed end of the isolation box 1. The cylinder 10 is horizontally arranged, and a scanner 6 is fixedly installed on the push rod of the cylinder 10. The scanner 6 is located inside the isolation box 1.

[0021] The closed end of the isolation box 1 has a through groove for the push rod to pass through, providing space for the push rod of the cylinder 10 to pass through. The cylinder 10 can push and pull the scanner 6 left and right. That is, when it moves to the left, it pulls the scanner 6 into the isolation box 1, and when it moves to the right, the scanning end of the scanner 6 extends out of the isolation box 1 to scan the QR code of the motor.

[0022] Scanner 6 is an existing component with a structure including a light source, optical lens, image sensor, and control circuit board, used to scan QR codes on motors.

[0023] Isolation doors 4 are hinged to the upper and lower sides of the open end of the isolation box 1 via torsion shafts 3. When no external force is applied, the isolation doors 4 can close and block the open end of the isolation box 1.

[0024] The upper isolation door 4 is provided with a cavity, and an exhaust pipe 7 connected to the cavity is installed on the lower side of the upper isolation door 4. An air exchange mechanism 8 is fixedly installed on the upper side of the isolation box 1, and the output end of the air exchange mechanism 8 is connected to the cavity.

[0025] The ventilation mechanism 8 is a device for air exchange, responsible for delivering air to the cavity of the upper isolation door 4 and then discharging it from the exhaust pipe 7 to achieve the functions of air filtration and pressurized output.

[0026] Please see Figure 2 The structure of the ventilation mechanism 8: The ventilation mechanism 8 includes an air filter cartridge 81, an air pump 82, and a hose 83. The air pump 82 is fixedly assembled with the isolation box 1. The air filter cartridge 81 is installed at the input end of the air pump 82, and the output end of the air pump 82 is connected to the cavity through the hose 83. The hose 83 is preferably a bamboo tube, which has good elasticity and durability and does not affect air delivery when the upper isolation door 4 swings.

[0027] The filter cartridge 81 is used to remove impurities, dust or harmful particles from the air to ensure that the air used is clean. The air pump 82 is used to pressurize and deliver the air, which is then delivered to the cavity through the hose 83.

[0028] The air filter cartridge 81 is an existing component consisting of a frame, end caps, and a non-woven fabric pleated tube, which has the function of purifying air. One end cap is connected to the input end of the air pump 82 by a threaded connection, which facilitates disassembly and replacement.

[0029] Please see Figure 4 The structure of torsion shaft 3: The torsion shaft 3 includes a torsion spring 31 and a pin 32. The isolation box 1 and the isolation door 4 are hinged together by the pin 32, and the two parts are connected by the hinge so that they can rotate relative to each other. The pin 32 is fitted with the torsion spring 31. One end of the torsion spring 31 is fixedly assembled with the isolation box 1, and the other end of the torsion spring 31 is fixedly assembled with the isolation door 4.

[0030] The torsion spring 31 can be subjected to force when it is pushed open, store torsional energy, and thus generate a rebound force; after the force of pushing it open disappears, the torsion spring 31 can help the two isolation doors 4 to reset and close at the open end of the isolation box 1.

[0031] Limiting plates 12 are fixedly installed on the opposite sides of the isolation doors 4. When the isolation doors 4 swing to the horizontal, the limiting plates 12 abut against the outer side wall of the isolation box 1 to prevent the isolation doors 4 from swinging too much and to ensure that the scanning end of the scanner 6 can always move horizontally.

[0032] Please see Figure 3 The structure of exhaust duct 7: Two exhaust pipes 7 are set at an angle, and the output direction of the exhaust pipes 7 is towards the acquisition end of the scanner 6; this can provide a more uniform airflow distribution, form an air curtain at the acquisition end of the scanner 6, reduce the influence of dust or other interference, thereby improving the acquisition stability of the scanner 6, and also facilitate airflow to ensure the operating temperature of the scanner 6.

[0033] To optimize the movement path of scanner 6: The scanner 6 has rotating rollers 5 mounted on both the upper and lower sides via roller frames. The rotating rollers 5 abut against the inner side wall of the isolation box 1 or the isolation door 4. The rotation of the rotating rollers 5 assists the scanner 6 in moving, ensuring that the scanner 6 moves in the center. The rotating rollers 5 also push open the two isolation doors 4 to prevent the scanner 6 from being rubbed.

[0034] To maintain the ambient temperature of scanner 6 when not in use: The closed end of the isolation box 1 is equipped with a one-way valve 9 and a temperature sensor 11. The one-way valve 9 is preferably a rubber duckbill valve. The temperature sensor 11 is used to monitor the temperature change inside the isolation box 1. When the temperature reaches the set value, the ventilation mechanism 8 also works to introduce clean air into the isolation box 1. The function of the one-way valve 9 is to only allow gas to be discharged from the inside of the isolation box 1 to the left, so as to cool down and protect the scanner 6.

[0035] To facilitate the installation of this equipment: Support feet 2 are fixedly installed on the bottom of both the front and rear sides of the isolation box 1. The support feet 2 have through holes for screws to pass through. The support feet 2 are made of L-shaped iron plates bent into shape. They are simple in shape and have high strength, so that the isolation box 1 can be fixed in the accurate scanning position by screw installation to prevent displacement and also provide sufficient room for the swing of the lower limiting plate 12.

[0036] The working principle of this embodiment: Cylinder 10, air pump 82, scanner 6, and temperature sensor 11 are connected to the industrial control electromechanical system of this workstation for collaborative operation.

[0037] Installation phase: Install the device on the workstation platform using support feet 2, and align the acquisition end of scanner 6 with the acquisition position of the motor on the turntable.

[0038] Scanning phase: When the motor to be scanned is driven by the turntable to the scanning position, the cylinder 10 pushes the scanner 6 to the right. The rotating roller 5 first moves along the inner side wall of the isolation box 1 to the right end, and then pushes open the two isolation doors 4 until the limit plate 12 abuts against the outer side wall of the isolation box 1. At this time, the isolation door 4 is in a horizontal state, and the output direction of the exhaust pipe 7 is towards the acquisition end of the scanner 6. At the same time, the ventilation mechanism 8 works, pressurizing the filtered clean air and inputting it into the cavity, and then discharging it from the exhaust pipe 7. This forms an air curtain at the acquisition end of the scanner 6, which has heat exchange capabilities and can also prevent dust and other debris from adhering to the acquisition end of the scanner 6, thus maintaining the normal rhythm of QR code acquisition.

[0039] Standby phase: When the scanner 6 is not used for a long time, the cylinder 10 pulls the scanner 6 back to the left, so that the scanner 6 enters the isolation box 1. At this time, the isolation door 4 is locked at the open end of the isolation box 1 by the torque of the torsion shaft 3, forming a complete sealed space. Meanwhile, the temperature sensor 11 can monitor the temperature inside the sealed space. When the temperature is higher than the set value, the ventilation mechanism 8 will work again. The clean air blown into the sealed space through the exhaust pipe 7 can exchange heat with the scanner 6. The air after heat exchange can be discharged from the one-way valve 9 to keep the ambient temperature of the scanner 6 within a suitable range.
