Sprockets are installed at the head pulley and tail pulley, and the sprockets are arranged around the main shaft. The sprockets mesh with the conveyor chain. The drive motor controls the rotation of the main shaft, thereby driving the sprockets and the conveyor chain to rotate. The assembly platform includes a conveyor component and a product fixture. The conveyor component is mounted on the conveying system, and the conveying system drives the conveyor component. The product fixture is fastened to the conveyor component and is used to assemble handrail locks.

[0068] The gear assembly module includes a first material handling mechanism, a first oil gun, and a first assembly mechanism, wherein: the first material handling mechanism is used to pick up the sector gear and the transmission gear to a designated position; the first oil gun applies oil to the sector gear and the transmission gear; and the first assembly mechanism assembles the sector gear and the transmission gear onto the end cover in sequence.

[0069] The locking assembly module includes a second material handling mechanism, a wave washer vibrating plate, a locking plate assembly module, and a pawl assembly module. The second material handling mechanism picks up the wave washer, locking plate, fixed-axis gear, and pawl to a designated position. The wave washer vibrating plate is used to transport the wave washer to the material handling point. The locking plate assembly module picks up the fixed-axis gear to a designated position and then picks up the locking plate to a designated position. The pawl assembly module assembles the pawl and pawl pin and then connects them to the fixed-axis gear.

[0070] The bolt assembly module includes a second oil gun, a flipping and material-retrieving mechanism, and a second assembly mechanism, wherein: the second oil gun injects oil into the lock cover; the flipping and material-retrieving mechanism flips the lock cover; and the second assembly mechanism assembles the flipped lock cover onto the product.

[0072] It also includes a performance testing module for testing the performance of handrail lock products.

[0073] An assembly method for an automatic assembly system based on the above-described handrail lock, provided by the present invention, is characterized by comprising the following steps:

[0074] Step 1: Manually place the gear cover, sector gear, transmission gear, fixed shaft gear, and lock cover onto the material tray of the assembly platform, and place the locking plate into the locking plate hopper of the assembly platform;

[0075] Step 2: The gear assembly module sequentially assembles the sector gear and transmission gear into the gear cover;

[0076] Step 3: The locking assembly module further assembles the wave washer, locking plate, fixed shaft gear, ratchet, and ratchet pin;

[0077] Step 4: Manually assemble the disc external gear assembly, the vehicle feel assembly, and the lock cover;

[0078] Step 5: The bolt assembly module assembles the lock cover onto the product;

[0079] Step 6: Use the performance testing module to perform performance testing on the assembled handrail lock.

[0080] In more detail, the working steps of this invention are as follows: At the initial position of the production line, parts are manually placed into fixtures, including end caps, sector gears, locking caps, transmission gear assemblies, and fixed-axis gear assemblies. All parts are placed on product jigs, which are then set up on an assembly platform. The assembly platform travels along the entire production line via a conveyor system, sequentially passing through the gear assembly module, locking assembly module, bolt assembly module, and performance testing module. The placement and assembly are checked using a detection system. For example, an IV camera is used to check for mis-installation of the sector gears, the fixed-axis gears, and whether the end caps or transmission gears are missing.

[0081] Figure 2 This is a schematic diagram of the assembled sector gear structure. The sector gear is picked up by a first material handling mechanism and positioned at the oiling point of the first oiling gun. Preferably, this is achieved through a sector gear rotation mechanism. Specifically, the first material handling mechanism picks up the sector gear and places it on the rotation mechanism. After the rotation mechanism rotates a certain angle, the first oiling gun applies oil to the sector gear. After oiling, the first material handling mechanism returns the sector gear to the product fixture.

[0082] Figure 3 The diagram illustrates the assembly of the transmission gear structure. Oil is injected into the two gear holes of the end cover using an oil gun. The first assembly mechanism then assembles the transmission gear assembly into its corresponding position on the end cover. After assembly, a detection device, such as a CCD camera, is used to photograph and check the angle of the transmission gear and whether it is properly installed.

[0083] Figure 4 The diagram illustrates the assembly of a wave-shaped washer. A wave-shaped washer vibratory feeder is used to load the washer, which then transports it to a pick-up point. A second pick-up mechanism then places the washer onto the sector gear of the product fixture. A GT sensor is used to detect over- or under-installation of wave-shaped washers.

[0084] Figure 5The schematic diagram of the locking plate assembly structure shows the locking plate assembly module. This module moves the fixed-axis gear to a designated position and then moves the locking plate to the designated position. Specifically, the locking plate is manually placed onto the magazine fixture; the divider rotates, moving the magazine fixture to the picking position; the lifting mechanism lifts the locking plate to the picking position; the first picking position of the picking mechanism picks the locking plate to the intermediate position for calibration; a barcode scanner scans the code, and an RFID reader reads the carrier's RFID tag, binding the locking plate's QR code to the carrier's RFID tag; the third picking position of the picking mechanism assembles the fixed-axis gear to the corresponding position on the end cover. The second picking position assembles the locking plate from the intermediate position onto the end cover.

[0085] Figure 6 The diagram shows the ratchet structure, including a ratchet assembly module, which comprises a ratchet vibrating plate and a ratchet pin vibrating plate. The assembly mechanism assembles the ratchet and ratchet pin and connects them to the fixed-axis gear.

[0086] After the pawl and pawl pin are installed, the disc external gear assembly and the vehicle sensing assembly are manually assembled and installed into the product. The IV camera is used to check whether the disc external gear assembly, the vehicle sensing assembly, and the lock cover are incorrectly or missing.

[0087] Figure 7 This is a schematic diagram of the locking cover oiling assembly structure. The second oil gun injects oil into the locking cover, the flipping and material-retrieving mechanism flips the locking cover, and the second assembly mechanism assembles the flipped locking cover onto the product.

[0088] Figure 8 This is a schematic diagram of a screw fastening structure. The screw sorting mechanism sorts the screws to the picking position; the moving mechanism moves the screw gun mechanism to the screw sorting mechanism to pick up the screws; the moving mechanism moves the screw gun mechanism to the product for fastening; the above actions are repeated to fasten multiple screws to the product. After fastening, the screws are height-checked to ensure they meet the height requirements, and finally the finished product is unloaded.

[0089] Finally, the performance of the product is tested through the performance testing module, which tests the acceleration, tilt angle, jamming, and flipping performance of the handrail lock. Acceleration sensors, tilt angle sensors, torque sensors and other testing devices can be used.

[0090] The overall process of this invention is controlled by a control system. The sequential actions of each module are set according to the assembly steps, and the corresponding actions are fed back by the detection instructions of the detection system, so as to realize the automated assembly of the handrail lock.
