In the initial state, the first lifting cylinder 2511 drives the jacking plate 2512 to fall below the jacking gap. When the carrier plate moves to a preset position below the positioning plate 252, the first lifting cylinder 2511 drives the jacking plate 2512 to rise.

The second lifting cylinder 362 can drive the push rod 361 to connect or disconnect from the tray. In the initial state, the second linear driving component 37 drives the material pushing component 36 to move below the tray, and then the second lifting cylinder drives the push rod 361 to rise so that the push rod 361 is connected to the tray. Then the second linear driving component 37 drives the material pushing component 36 to move forward, so that the push rod 361 drives the bottommost tray in the stacking mechanism 9 to be conveyed forward through the material passing gap 911.

The second vision detection component 55 is used to detect the state of the second product. When the third linear driving component 53 drives the first vision detection component 54 to move above the second conveying mechanism 3, the first vision detection component 54 obtains the specific position of the second product in the coordinate system of the assembling device, guides the assembling component 52 to pick up the material, and then the third linear driving component 53 drives the first vision detection component 54 to leave above the second conveying mechanism 3 to avoid the assembling component 52 from picking up the material.

[0065] And / or the assembling mechanism 5 further includes a second vision detection component 55. The third linear driving component 53 is drivingly connected to the second vision detection component 55 along the first direction, so that the second vision detection component 55 can move above the first conveying mechanism 2. The second vision detection component 55 is used to detect the state of the first product. When the third linear driving component 53 drives the second vision detection component 55 to move above the first conveying mechanism 2, the second vision detection component 55 obtains the specific position of the first product in the coordinate system of the assembling device, guides the assembling component 52 to assemble the second product onto the first product, and then the third linear driving component 53 drives the second vision detection component 55 to leave above the first conveying mechanism 2 to avoid the assembling component 52 from assembling.

[0066] And / or the assembling device further includes a third vision detection component 8. The third vision detection component 8 is located between the first conveying mechanism 2 and the second conveying mechanism 3, and the third vision detection component 8 is located below the gantry 4. The third vision detection component 8 is used to detect the state of the second product picked up by the assembling component 52.

[0067] In this embodiment, the assembly mechanism 5 includes a third linear drive assembly 53, a first vision detection assembly 54, and a second vision detection assembly 55.

The first vision detection assembly 54, the second vision detection assembly 55, and the third vision detection assembly 8 can all adopt mechanisms such as CCD camera detection, which are prior arts, and their specific structures and working principles will not be elaborated here.

[0068] In this embodiment, the first linear drive assembly 51, the second linear drive assembly 37, and the third linear drive assembly 53 can all adopt structures such as linear drive modules, which are prior arts, and their specific structures and working principles will not be elaborated here.

[0069] It should be particularly noted that as Figures 1-5 shown, this embodiment also provides the working steps of the assembly device, which are specifically as follows:

[0070] In this embodiment, taking the first assembly station 22 responsible for assembling product one and product two, and the second assembly station 23 responsible for assembling product three and product four as an example. When the carrier plate reaches the preset position, the metal inductor senses the carrier plate and transmits the carrier plate in-place signal to the PLC. The PLC determines whether to release it. If there is a carrier plate at the first assembly station 22, it will not be released, playing the role of temporarily storing the carrier plate. If there is no carrier plate at the first assembly station 22, it will be released: The PLC gives an analog signal to the solenoid valve, making the solenoid valve coil energized and act, changing the air flow direction of the third lifting cylinder 2551, causing the third lifting cylinder 2551 to act, and the blocking member 2552 descends below the jacking gap. The stepping motor rotates, and the conveyor belt drives the carrier plate to move forward.

[0071] When the carrier plate reaches the first assembly station 22, the metal inductor senses the carrier plate and transmits the in-place signal to the PLC, controlling the PLC to be able to act. The PLC controls the first lifting cylinder 2511 to act, jacking up the carrier plate to the working position, and fixing the position of the carrier plate in the coordinate system of the assembly device by the positioning plate 252. Whether it is in place is determined by the end magnetic ring signal on the first lifting cylinder 2511, and finally the signal is input to the PLC to control the PLC to execute the next action.

[0072] After the jacking is in place, the PLC controls the third linear drive assembly 53 to act. The second vision detection assembly 55 takes a picture of Product 1, identifies the features, inputs the data into a computer for data processing, and processes the data with professional vision software to tell the specific coordinates of the assembly component 52 in the coordinate system of the assembly equipment. At this time, there are two cases: whether there is material on the assembly component 52 or not. In the first case, when there is material, the assembly is directly carried out according to the coordinates of the product. In the second case, when there is no material, the PLC controls the third linear drive assembly 53 to act. The second vision detection assembly 55 takes a picture of Product 2 to obtain the specific position of Product 2 in the coordinate system of the assembly equipment, and the vision software tells the PLC the coordinates of Product 2. The PLC controls the assembly component 52 to pick up the material. The assembly component 52 reaches the specified position, the Z-axis descends, and the suction nozzle or gripper reaches the position of Product 2. The vacuum is turned on or the gripper is closed to complete the picking of Product 2. The Z-axis reaches the standby position, and the assembly component 52 moves along the first direction to above the third vision detection assembly 8.
