[0048] A grille loading area is provided on one side close to the transport line 1, and the second material 7 is placed in the grille loading area. When the transport line 1 drives the first material 6 to move to the first assembly station 2, the transport line 1 stops running, and the locking device 4 moves to the grille loading area and adsorbs the second material 7. Then, the locking device 4 moves the adsorbed second material 7 to the first assembly station 2, and then the locking device 4 drives the second material 7 to rotate, so as to lock the second material 7 on the first material 6. This embodiment takes the first material as the air conditioner outdoor unit panel and the second material as the grille as an example.

[0049] The first material 6 is provided with a slot 24, and the second material 7 is provided with a buckle 23, and the buckle 23 and the slot 24 are adapted. Preferably, there are multiple buckles 23 and slots 24, respectively, and the multiple buckles 23 correspond to the multiple slots 24 one by one. The rotating mechanism 8 inserts the buckle 23 of the second material 7 into the slot 24 of the first material 6, and the rotating mechanism 8 drives the second material 7 to rotate, and locks the second material 7 on the first material 6.

[0053] Example 2

[0054] like Figure 1-Figure 9 As shown, this embodiment provides a material assembly system, including a transportation line 1, on which a first assembly station 2 and a second assembly station 3 are adjacently arranged, a locking device 4 is arranged near the first assembly station 2, and a screw driving device 5 is arranged near the second assembly station 3; a first material 6 is placed on the transportation line 1, and when the transportation line 1 drives the first material 6 to move to the first assembly station 2, the locking device 4 locks the second material 7 on the first material 6 in a rotating manner; when the first material 6 moves to the second assembly station 3, the screw driving device 5 is used to screw the screw 8 into the first material 6 and the second material 7.

[0055] The locking device 4 includes a rotating mechanism 9 , and the rotating mechanism 9 is connected to a motor. The rotating mechanism 9 is used to drive the second material 7 to rotate so as to clamp the second material 7 into the first material 6 .

[0056] The rotating mechanism 9 is a disc-shaped structure, and an electromagnetic coil 11 is disposed inside the rotating mechanism 9 .

[0057] The locking device 4 further includes a first shell 12 . The first shell 12 is located at a side of the motor away from the rotating mechanism 9 , and the first shell 12 is connected to the motor.

[0058] The first material 6 of this embodiment is an air conditioner exterior panel, and the second material 7 is a grille. The rotating mechanism 9 is connected to the output shaft of the rotating motor 10, and the motor is placed in the housing. The rotating mechanism 9 is a disc-shaped structure, and a circular ring-shaped electromagnetic coil 11 is arranged in the rotating mechanism 9. The rotating mechanism 9 is electrically connected to the power supply. When the power supply supplies power to the electromagnetic coil 11 in the rotating mechanism 9, the electromagnetic coil 11 generates magnetic force; when the power supply does not supply power to the electromagnetic coil 11 in the rotating mechanism 9, the electromagnetic coil 11 has no magnetic force.

[0059] A photoelectric sensor is respectively arranged near the first assembly station 2 and the second assembly station 3, and the photoelectric sensor is used to detect whether the air conditioner outdoor unit panel has reached the first assembly station 2 or the second assembly station 3. When the air conditioner outdoor unit panel reaches the first assembly station 2, the photoelectric sensor feeds back the signal to the PLC (Programmable Logic Controller). After receiving the signal, the PLC controls the first blocking mechanism 21 to pop up, locate the air conditioner outdoor unit panel, and the transport line 1 stops running. The rotating mechanism 9 is controlled to move to the grille loading area, and power is supplied to the rotating mechanism 9, so that the electromagnetic coil 11 in the rotating mechanism 9 generates magnetic force, and the rotating mechanism 9 adsorbs the grille.

[0060] The visual recognition device is used to accurately locate the installation area, and the rotating mechanism 9 transfers the grille to the installation area and then puts it down. The installation area is an area above the first assembly station 2. The rotating mechanism 9 is also connected to a driving cylinder, and a buckle 23 is provided on the grille. After the grille is in place, the driving cylinder drives the rotating mechanism 9 to press down until the rotating mechanism 9 aligns the buckle 23 on the grille with the slot 24 placed in the air conditioner outdoor panel, controls the rotating mechanism 9 to rotate, and uses the friction force on the surface of the rotating mechanism 9 when rotating to snap the grille into the slot 24, so that the grille is assembled on the air conditioner outdoor panel.

[0061] The surface of the rotating mechanism 9 is made of rubber material to prevent excessive downward pressure on the rotating mechanism 9 during the bonding process, which may cause deformation of the air conditioner outdoor unit panel.

[0062] When the locking process of the outdoor unit grille is completed, the first blocking mechanism 21 is reset, and the outdoor unit panel of the air conditioner flows into the automatic screw driving area 8.

[0063] The locking device 4 of this embodiment includes a rotating mechanism 9, which is connected to a rotating motor 10, and is used to drive the second material 7 to rotate so as to insert the second material 7 into the first material 6. The rotating mechanism 9 is a disc-shaped structure, and an electromagnetic coil 11 is arranged in the rotating mechanism 9. When the air conditioner outdoor unit panel arrives at the first assembly station 2, the first blocking mechanism 21 is controlled to pop out, the air conditioner outdoor unit panel is positioned, and the transportation line 1 stops running. The rotating mechanism 9 is controlled to move to the grille loading area, and power is supplied to the rotating mechanism 9, so that the electromagnetic coil 11 in the rotating mechanism 9 generates magnetic force, and the rotating mechanism 9 adsorbs the grille. After the grille is in place, the driving cylinder drives the rotating mechanism 9 to press down until the rotating mechanism 9 aligns the buckle 23 on the grille with the slot 24 into which the air conditioner outdoor unit panel is placed, and controls the rotating mechanism 9 to rotate, and uses the friction force on the surface of the rotating mechanism 9 when rotating to insert the grille into the slot 24, so that the grille is assembled on the air conditioner outdoor unit panel. The above-mentioned automated assembly method can improve the assembly efficiency of the grille and the air conditioner outdoor unit panel.

The feed pipe 20 is connected to the second through hole 18, and the second through hole 18 is connected to the first through hole 16. The screw 8 enters the second through hole 18 from the feed pipe 20, and then enters the first through hole 16 and is clamped by the first through hole 16. When the screw 8 is clamped in the first through hole 16, the screw rod 17 of the screw 8 passes through the first through hole 16, and the nut of the screw 8 is clamped above the first through hole 16. When the two clamping jaws 14 abut against each other, the first through hole 16 is formed between the two clamping jaws 14, and the screw 8 is clamped after the screw 8 passes through the first through hole 16.

The end of the screwdriver 19 away from the second through hole 18 is connected to a screw tightening motor. The motor shaft of the screw tightening motor is connected to the screwdriver 19, and the motor shaft of the screw tightening motor drives the screwdriver 19 to press down and pass through the second through hole 18 until the screwdriver 19 abuts against the nut of the screw 8. The clamping mechanism 13 drives the screw 8 to move above the second screw hole of the second material 7, and aligns the screw 8 with the second screw hole and the first screw hole. At this time, the two clamps 14 of the clamping mechanism 13 are opened, and the screw 8 is no longer clamped. The screw 8 falls directly into the second screw hole of the second material 7 and the first screw hole of the first material 6. The screw tightening motor is started, and the screw tightening motor drives the screwdriver 19 to rotate, and the screwdriver 19 drives the screw 8 to rotate, so as to tighten the screw 8 in the second screw hole of the second material 7 and the first screw hole of the first material 6, so that the second material 7 is fixed on the first material 6.

[0077] This embodiment further provides a material automatic assembly method, based on the material assembly system described in any one of Embodiments 1 to 3, the method comprising:

[0078] S1: Start the transport line. If the first material arrives at the first assembly station, pause the transport line.

[0079] S2: Control the locking device to adsorb the second material.

[0080] S3: Control the locking device to align the second material with the first material.

[0081] S4: Control the rotating mechanism to drive the second material to rotate until the second material is stuck into the slot of the first material.

[0082] S5: Start the transport line, and if the first material arrives at the second assembly station, pause the transport line.

After receiving the signal, the PLC controls the first blocking mechanism 21 to extend to prevent the first material 6 from continuing to move, and at the same time controls the transport line 1 to stop operating.

[0095] Then, the locking device 4 is controlled to move to the top of the loading area, and power is supplied to the rotating mechanism 9, so that the electromagnetic coil 11 in the rotating mechanism 9 generates magnetic force. The rotating mechanism 9 automatically absorbs the second material 7 through magnetic force, and accurately locates it to the first assembly station 2 through the visual recognition device. After the rotating mechanism 9 absorbs the second material 7, it moves to the first assembly station 2, and aligns the second material 7 with the first material 6 before putting the second material 7 down. When the second material 7 is located at the first assembly station 2, the cylinder is started, and the cylinder drives the rotating mechanism 9 to press down, and the rotating mechanism 9 is driven to rotate by the motor, and the rotating mechanism 9 then drives the second material 7 to rotate, so that the second material 7 is stuck in the slot 24 of the first material 6.

[0096] After the locking device 4 completes the locking process of the second material 7 and the first material 6, the first blocking mechanism 21 is controlled to retract, and the transport line 1 is started. The transport line 1 drives the first material 6 to continue to move to the second assembly station 3. When the photoelectric sensor senses that the first material 6 is located at the second assembly station 3, the output signal is fed back to the PLC. After the PLC receives the signal, the second blocking mechanism 22 extends to prevent the first material 6 from continuing to move, and at the same time controls the transport line 1 to stop operating.

[0097] Then, an industrial camera is used to take a picture, and the second screw hole of the second material 7 is identified. The captured information is sent to the screw driving device 5, and the screw driving device 5 moves to the top of the second screw hole according to the generated path. The screw driving device 5 feeds the screw 8 in the feeding tube 20 into the second through hole 18, and the screw 8 falls into the first through hole 16 through the second through hole 18. At this time, the two clamping jaws 14 of the clamping mechanism 13 clamp the screw 8, and the screwdriver 19 passes through the second through hole 18 and moves downward until the screwdriver 19 abuts against the screw 8. The screw driving device 5 drives the screw 8 to press down until the screw 8 is aligned with the screw holes of the first material 6 and the second material 7, and controls the two clamping jaws 14 of the clamping mechanism 13 to open, so that the screw 8 falls directly into the screw holes of the first material 6 and the second material 7. The motor shaft of the screw tightening motor drives the screwdriver 19 to rotate, and the screwdriver 19 rotates to screw the screw 8 into the screw holes of the first material 6 and the second material 7.

[0098] After the screw driving device 5 screws the screw 8 into the first screw hole of the first material 6 and the second screw hole of the second material 7, the second blocking mechanism 22 is controlled to retract, and the conveyor line 1 is restarted. The conveyor line 1 drives the first material 6 to continue to move to the inspection station, and the industrial camera is used to take pictures to obtain the assembled images of the first material 6 and the second material 7, and the height difference is compared with the correctly assembled image in the system to identify whether it meets the requirements. If the system determines that the assembly is successful, the second material 7 flows into the next station; if the system determines that the installation fails, an alarm signal is issued to remind the manual offline.

[0099] When the transport line 1 of this embodiment drives the first material 6 to move to the second assembly station 3, the screw driving device 5 moves to the top of the screw hole 8 of the first material 6 and the second material 7, and the screw 8 in the feeding tube 20 is fed into the second through hole 18, and then fed into the first through hole 16 through the second through hole 18. The screw 8 is clamped by the two clamping claws 14 of the clamping mechanism 13, and the screw driver 19 is controlled to move downward until it contacts the screw 8. Then the screw driving device 5 is controlled to drive the screw 8 to press down, and the screw 8 is directly aligned with the screw hole 8 on the first material 6 and the second material 7. The two clamping claws 14 are opened to make the screw 8 fall into the screw hole 8, and then the motor shaft of the screw driving motor is controlled to drive the screw driver 19 to rotate, so as to screw the screw 8 into the screw hole 8 of the first material 6 and the second material 7. In the above process, the second material 7 is automatically clamped into the first material 6 by using the locking device 4, which solves the problem of high labor intensity and low efficiency in manual assembly, greatly improves production efficiency, reduces labor costs, and achieves the purpose of reducing staff and increasing efficiency. By utilizing the screw driving device 5, automatic screw driving 8 is realized on the second material 7 and the first material 6, thereby solving the problem of missing screws 8 or not tightening the screws 8 during manual assembly. This allows the second material 7 to be assembled on the first material 6 with higher assembly accuracy, and the torque for driving the screws 8 is also relatively stable, thereby greatly improving the production quality.
