Description

Technical Field

[0001] This application relates to the field of duct fan assembly, and in particular to a bolt fastening device with barcode scanning and detection functions. Background Technology

[0002] A fan is a machine that uses input mechanical energy to increase gas pressure and discharge gas; it is a type of driven fluid machinery. The term "fan" is a common abbreviation for gas compression and gas transport machinery, and commonly refers to ventilators, blowers, and wind turbines.

[0003] A duct fan is a type of fan that adjusts the position of the air inlet and outlet by controlling the air duct on the casing. Since the position and volume of the air inlet and outlet need to be controlled by controlling each ventilation hole, duct fans usually require screwing during assembly. Existing screw fastening devices can use a robotic arm to drive an electric screwdriver to move to a preset position for automatic screw tightening. However, when errors occur during the assembly of the duct fan, the electric screwdriver not only fails to tighten the screws when rotating in the preset position, but also easily damages the duct fan. Utility Model Content

[0004] In order to reduce the probability of damage to the air duct fan caused by assembly errors by electric screwdrivers, this application provides a bolt fastening device with barcode scanning and detection functions.

[0005] The bolt fastening device with barcode scanning and detection functions provided in this application adopts the following technical solution:

[0006] A bolt fastening device with barcode scanning and detection functions includes a body, a conveyor belt arranged along the length of the body, a screw frame arranged on the body, a screw assembly mounted on the screw frame, and a detection frame mounted on the body. The detection frame is installed on the side of the screw frame facing the conveyor belt input and a detection head is mounted on the detection frame.

[0007] By adopting the above technical solution, the detection head can detect whether there are assembly errors in the installation of the duct components and the fan. When errors are found, the screwing of the duct components and the fan is stopped, allowing the duct components and the fan to pass directly through the screw assembly, thereby reducing the probability of the electric screwdriver damaging the duct and the fan due to assembly errors.

[0008] Optionally, a sweeping dock is installed on the detection frame.

[0009] By adopting the above technical solution, different QR codes are affixed to different fixtures, and the products inside the fixtures are distinguished by scanning the QR codes at the dock, so that screws can be tightened in different positions according to different products.

The length sliding cylinder is mounted on the screw holder, the width sliding cylinder is mounted on the length sliding cylinder, the height sliding cylinder is mounted on the width sliding cylinder, and the electric screwdriver is mounted on the height sliding cylinder.

[0013] By adopting the above technical solution, the electric screwdriver can be adjusted on three axes using length sliding cylinders, width sliding cylinders, and height sliding cylinders, enabling the electric screwdriver to move to the accurate position for screwing.

[0014] Optionally, the screw holder may have two sets of screw assemblies.

[0015] By adopting the above technical solution, the two sets of screw assemblies can increase the speed of screw tightening and improve production efficiency.

[0016] Optionally, one end of the width sliding cylinder is mounted on the length sliding cylinder, and a guide frame is provided on the other end of the width sliding cylinder on the machine body, with the other end of the width sliding cylinder slidably mounted on the guide frame.

[0017] By adopting the above technical solution, the guide frame can be used to support the width sliding cylinder and also guide the width sliding cylinder.

[0018] Optionally, the electric screwdriver is equipped with a screw feeder at the bit end.

[0019] By adopting the above technical solution, the screw feeder head can be connected to a screw source to provide screws to the machine body.

Therefore, they should not be construed as limitations on this application. Furthermore, the use of numerical quantifiers such as "first," "second," and "third" is for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, interference fits, transition fits, or integral connections; they can refer to direct connections or indirect connections through an intermediate medium. Therefore, those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0034] This application discloses a bolt fastening device with barcode scanning and detection functions, referring to... Figure 1 The system includes a frame 1 mounted on the ground. A conveyor belt 2 is installed along the length of the frame 1. The conveyor belt 2 is used to transport fixtures for placing air duct components and fans. A screw frame 3 is installed on the frame 1. A screw assembly 4 is installed on the screw frame 3. The screw assembly 4 can screw the air duct components and fans. A detection frame 5 is installed on the frame 1. The detection frame 5 is installed on the side of the screw frame 3 facing the input of the conveyor belt 2. A detection head 6 is installed on the detection frame 5. In this embodiment, the detection head 6 is a camera. The camera can transmit the captured images to the computer processing end for detection, thereby determining whether the installation position of the air duct components and fans is correct. When there is an error, the screwing of the air duct components and fans is canceled, so that the air duct components and fans directly pass through the screw assembly 4, reducing the probability of the electric screw machine 44 damaging the air duct and fans due to assembly errors.

[0035] Reference Figure 1The inspection frame 5 is equipped with a scanning dock 7. By affixing different QR codes to different fixtures, the scanning dock 7 scans the QR codes to distinguish the products inside the fixtures according to their different fixtures. This allows for screw tightening at different positions based on the different products. The scanning dock 7 is positioned in front of the inspection head 6. After scanning the codes with the scanning dock 7 to determine the product model, inspection is performed based on the product model, reducing the probability of inspection errors. Both the inspection head 6 and the scanning dock 7 are mounted on the inspection frame 5 via mounting blocks 8. The mounting blocks 8 are mounted on the inspection frame 5 with bolts and nuts. Loosening the bolts allows the mounting blocks 8 to slide along the width of the inspection frame 5. The inspection head 6 and the scanning dock 7 are both slidably mounted on the inspection frame 5 along the width of the machine body 1 via the mounting blocks 8. The sliding of the inspection head 6 and the scanning dock 7 can be adjusted appropriately according to the position of the fixture.

[0036] Reference Figure 1 The screw assembly 4 includes a length sliding cylinder 41, a width sliding cylinder 42, a height sliding cylinder 43, and an electric screwdriver 44. The length sliding cylinder 41 is mounted on the screw holder 3, the width sliding cylinder 42 is mounted on the length sliding cylinder 41, the height sliding cylinder 43 is mounted on the width sliding cylinder 42, and the electric screwdriver 44 is mounted on the height sliding cylinder 43. The electric screwdriver 44 is adjusted on three axes by the length sliding cylinder 41, the width sliding cylinder 42, and the height sliding cylinder 43, so that the electric screwdriver 44 can be adjusted. The screw machine 44 can move to the accurate position to tighten screws; two sets of screw components 4 are set on the screw frame 3, which can increase the screw tightening speed and improve production efficiency; one end of the width sliding cylinder 42 is installed on the length sliding cylinder 41 in the length direction, and the other end of the machine body 1 is provided with a guide frame 9. The other end of the width sliding cylinder 42 is slidably set on the guide frame 9. The guide frame 9 can be used to support the width sliding cylinder 42 and guide the width sliding cylinder 42.

[0037] Reference Figure 1 and Figure 2 The electric screwdriver 44 has a screw feeder 10 fixedly installed at the bit. The screw feeder 10 has an inlet 11 and an outlet 12. The inlet 11 is located on the side wall of the screw feeder 10, and the outlet 12 is located at the bottom of the screw feeder 10 and faces the conveyor belt 2. The inlet 11 is connected to the screw source through a pipe and the screw is sent into the screw feeder 10 by an air pump. The screw is then discharged from the outlet 12 to the position of the air duct assembly where screws need to be screwed. The screw bit of the electric screwdriver 44 is inserted into the screw feeder 10 from directly above the outlet 12. The electric screwdriver 44 is driven by the height sliding cylinder 43, so that the screw bit of the electric screwdriver 44 pushes the screw out of the outlet 12 and abuts against the air duct assembly. Then, the electric screwdriver 44 drives the screw bit to rotate and screw the screws into the air duct assembly.

[0038] Reference Figure 1 and Figure 3 The machine body 1 is equipped with a defective product removal component 13, which is located on the side of the screw assembly 4 away from the detection head 6. The defective product removal component 13 includes a defective product rack 131 mounted on the machine body 1 and a defective product robot 132 mounted on the defective product rack 131. The defective product robot 132 includes a cylinder that drives along the width and height directions of the machine body 1 and a gripper cylinder mounted on the cylinder. The gripper cylinder removes the defective products from the fixture, reducing the probability of the air duct assembly and fan entering the subsequent assembly. A defective product box 14 is placed on the machine body 1, and the removed defective products are placed in the defective product box 14 for easy storage and subsequent handling.

[0039] The implementation principle of this application embodiment is as follows: The fixture equipped with the air duct assembly and the fan is conveyed along the length of the machine body 1 via the conveyor belt 2. After the fixture is scanned by the barcode scanner 7, the model of the air duct assembly is identified. Then, the inspection head 6 is used to check for assembly errors. If there are no assembly errors, the fixture is conveyed to the screw assembly 4, and the screws at the connection between the air duct assembly and the fan are tightened by the bolt assembly. After that, the fixture is sent out of the machine body 1 via the conveyor belt 2 for subsequent assembly. When there are errors, the screw assembly 4 does not work when the fixture is conveyed to the screw assembly 4. When the fixture is conveyed to the defective product removal assembly 13, the defective product robot 132 removes the air duct assembly and the fan from the fixture and places them in the defective product box 14 for storage.
