The conveying device 2 is used to sequentially convey the carrier 20 to the loading / unloading device 3, the first assembly device 4, the second assembly device 5, the laser engraving device 9, and the airtightness testing device 10, and finally return it to the loading / unloading device 3. The loading / unloading device 3 is used to monitor the load. The system automates multiple processes, including photographing and scanning workpieces, providing locations for manual loading and unloading, assembling a PCB board, product bottom shell, and product top cover, engraving QR codes and product sequence numbers, testing leakage rates after pressure holding, and unloading. This high level of automation meets current production needs. More specifically, the process is as follows: Please see Figures 1 to 2The loading and unloading device 3 includes an information processing center (not shown), a barcode scanning component 31, and a camera component 32. Both the barcode scanning component 31 and the camera component 32 are electrically connected to the information processing center and are mounted on the frame 1. The information processing center is located outside the equipment. The barcode scanning component scans the workpieces on the carrier 20, and the camera component 32 takes pictures to determine the position of the workpieces. The barcode scanning component 31 and the camera component 32 feed back relevant information to the information processing center, which records the corresponding information.

With the image obtained by the bottom camera mechanism 7, the material handling mechanism 6 transports the workpiece to be assembled to the mating workpiece at the assembly station 11. The press mechanism 8 is used to fasten the two workpieces together. Because of the presence of the press mechanism 8, the press mechanism 8 itself can better control the downward pressure, which can avoid excessive pressure when the first workpiece presses against the second workpiece, thereby better protecting the workpiece. The integration of servo press and bottom vision achieves high-precision shell fastening, which can effectively protect the assembled products and improve the pass rate. For example, the first assembly device 4 assembles the PCB board onto the lower shell using the image acquisition mechanism 6 obtained by the bottom camera mechanism 7, and the second assembly device 5 assembles the upper cover onto the lower shell using the image acquisition mechanism 6 obtained by the bottom camera mechanism 7.

The transverse cylinder is mounted on the frame 1, the lifting cylinder is mounted on the output end of the transverse cylinder, the tilting cylinder is mounted on the output end of the lifting cylinder, and the gripper 102 is mounted on the output end of the tilting cylinder. The transverse cylinder, the lifting cylinder, and the tilting cylinder cooperate with each other to realize the movement and rotation of the gripper 102. The lifting cylinder descends, and the gripper 102, driven by the gripper 102 cylinder, grips the laser-engraved product. After the lifting cylinder rises, the flipping cylinder flips, and the lateral cylinder moves to place the product on the airtightness test position 20c on the carrier. The airtightness plug 1032, driven by the airtightness cylinder 1031, descends to maintain pressure on the workpiece. After the plug blocks the PIN port, air is injected into the product to 50 kPa. After maintaining pressure for a period of time, the leakage rate is tested. After the test is completed, the airtightness plug 1032, driven by the airtightness cylinder 1031, rises.

[0033] Please see Figures 1 to 8The conveying device 2 includes a chain drive mechanism 21, a track 22, and guide rollers 23 mounted on the bottom of the carrier. The track 22 is mounted on the frame 1, and the guide rollers 23 are located at the bottom of the carrier, rolling on both sides of the track 22. The guide rollers 23 clamp the track 22 on both sides and roll. In this embodiment, one carrier corresponds to four guide rollers 23, and the four guide rollers 23 clamp the track 22 and move. The chain drive mechanism 21 is mounted on the frame 1, and the output end of the chain drive mechanism 21 is connected to the carrier. The carrier runs on the track 22 under the drive of the chain drive mechanism 21. Preferably, the track 22 is a circular track 22, which includes a processing section and a return section connected in sequence, but is not limited thereto. The two assembly devices are arranged at intervals along the transmission direction of the conveying device 2. Specifically, hard alloy guide rollers 23 are installed at the bottom of the carrier and embedded in the V-shaped grooves on both sides of the track 22 to suppress lateral swaying. The carrier is equipped with a sensor plate, and the track 22 is equipped with a slotted photoelectric sensor. Together with the servo motor, closed-loop control is achieved to reduce the deviation of the carrier's docking position. When the carrier docks, the cylinder at the workstation drives the positioning cam follower to insert into the positioning hole at the bottom of the carrier. Its tolerance is H / g, eliminating the remaining error.

The chain 213 is connected to the vehicle through the vehicle connecting plate 30, and the chain 213 synchronously pulls the vehicle through the vehicle connecting plate. The chain drive device 212 is a servo motor with a sensor. The synchronous drive of the chain 213 combined with the closed-loop feedback of the sensor motor and the dynamic adjustment of the servo motor solves the problem of cumulative error of the chain 213. A high-precision circular track 22 conveying system is adopted: chain 213 drive + real-time compensation: the chain 213 synchronously drives the carrier, combined with encoder feedback, to achieve closed-loop control and high positioning accuracy; the carrier spacing is programmable: the main control system dynamically optimizes the carrier distribution to adapt to workpieces of different sizes.

[0035] Please see Figure 7 The carrier includes a first bearing position 20a, a second bearing position 20b, an airtightness test position 20c, a third bearing position 20d, and a fourth bearing position 20e, which are spaced apart on the carrier.

The completed products are returned to the loading / unloading device 3 for manual unloading.

[0037] By combining a conveyor device 2, a loading / unloading device 3, a first assembly device 4, a second assembly device 5, a laser engraving device 9, and an airtightness testing device 10, the conveyor device 2 sequentially transports the carrier to the loading / unloading device 3, the first assembly device 4, the second assembly device 5, the laser engraving device 9, and the airtightness testing device 10, and finally returns to the loading / unloading device 3.
