[0022] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 6 As shown, an automatic feeding and grabbing mechanism for fire doors includes a frame 1, a conveyor belt 2 is arranged on the frame 1, one end of the conveyor belt 2 is connected to a production line for conveying fire doors, and the other end is connected to a fire door processing device, the frame 1 is provided with a mounting frame 3 above the conveyor belt 2, the mounting frame 3 is provided with a clamping assembly, the clamping assembly is used to clamp the fire door on the conveyor belt 2, and the frame 1 is also provided with a driving device 5, the driving device 5 is used to drive the mounting frame 3 to move to one side of the processing equipment, and send the fire door clamped on the clamping assembly into the processing equipment. When the fire door is sent into the processing equipment, the clamping assembly releases the clamping of the fire door, and the driving device 5 drives the mounting frame 3 to push out of the processing equipment, completing the feeding and grabbing process.

[0024] Among them, the first clamping assembly 4 includes a first vacuum suction cup 6, and the first connecting rod 7 is hinged on both sides of the first vacuum suction cup 6. The first connecting rod 7 is L-shaped, and the L-shaped first connecting rod 7 consists of a long end and a short end. The first vacuum suction cup 6 is hinged to the long end of the first connecting rod 7, and the connection between the long end and the short end of the first connecting rod 7 is hinged on the mounting frame 3. The mounting frame 3 is also hinged with a pusher 8, and the ejection end of the pusher 8 is hinged to the short end of the first connecting rod 7. The pusher 8 can be an electric push rod, a cylinder, etc. In addition, a second connecting rod 33 is also provided on the first vacuum suction cup 6 and the mounting frame 3. One end of the second connecting rod 33 is hinged on the first vacuum suction cup 6, and the other end is hinged on the mounting frame 3. The first vacuum suction cup 6 can be supported by the second connecting rod 33 to improve the stability of the first vacuum suction cup 6. When the fire door needs to be grabbed, the ejection end of the pushing member 8 contracts, driving the first connecting rod 7 to rotate on the mounting frame 3, and the first vacuum suction cup 6 hinged on the first connecting rod 7 moves downward under the drive of the contraction of the ejection end of the pushing member 8, so that the first vacuum suction cup 6 abuts against the fire door on the conveyor belt 2, and the first vacuum suction cup 6 is controlled to clamp the fire door, thereby completing the clamping action of the fire door.

[0025] In addition, a second clamping assembly 24 is also provided on the mounting frame 3, and the second clamping assembly 24 is arranged between the first clamping assemblies 4. The second clamping assembly 24 includes a mounting frame 25 arranged on the mounting frame 3, and two connecting plates 27 are hinged on the mounting frame 25 through a first mounting shaft 26, and a fixing plate 29 is hinged between the two connecting plates 27 through a second mounting shaft 28. A first electric push rod 22 is provided on one of the two first mounting shafts 26, and the ejection end of the first electric push rod 22 is connected to a second mounting shaft 28 farthest from it, and a second vacuum plate 30 is provided at the bottom of the fixing plate 29. The second vacuum suction cup can be driven to move up and down by the extension and retraction of the first electric push rod 22, so as to clamp the fire door. Since the two first vacuum suction cups 6 of the first clamping assembly 4 are spaced apart at a large distance, and the two second vacuum suction cups of the second clamping assembly 24 are spaced apart at a small distance, the first clamping assembly 4 is mostly used to clamp larger fire doors, and the second clamping assembly 24 is mostly used to clamp smaller fire doors.

[0026] In detail, the frame 1 is provided with a mounting plate 9 above the mounting frame 3, a slide seat 10 is provided on the bottom of the mounting plate 9, a slide rail 11 is provided at a corresponding position on the mounting frame 3, and the slide rail 11 is slidably fitted in the slide seat 10. In more detail, the driving device 5 includes a transmission rod 12 provided on the mounting plate 9, a transmission mechanism is connected to a motor 13, a driving gear and a driven gear are provided on the transmission rod 12, the driven gear is connected to the output end of the motor 13 through a transmission chain 15, and the transmission rod 12 is driven to rotate by the motor 13. In addition, the mounting frame 3 is provided with first vertical plates 14 at both ends of the transplanting direction, and the transplanting direction is the moving direction of the fire door. A transmission chain 15 is connected between the two first vertical plates 14, and the transmission chain 15 is connected to the driving gear on the transmission rod 12, and the mounting plate 9 is provided with transmission gears on both sides of the driving gear, and the transmission gears ensure the coordination between the transmission chain 15 and the driving gear. The transmission rod 12 is driven to rotate by the motor 13, and the rotation of the transmission rod 12 drives the driving gear to rotate, thereby driving the transmission chain 15 between the two vertical plates to move, thereby driving the installation plate 9 to move closer to the processing equipment and away from the processing equipment.

[0027] In some embodiments, a support member 16 is provided on the frame 1, and the mounting frame 3 is provided on the support member 16. The support member 16 includes a second vertical plate 17 opposite to the frame 1, and a roller 18 is provided on the second vertical plate 17, and the roller 18 abuts against the bottom of the mounting frame 3 to reduce the friction when the mounting frame 3 moves, so as to facilitate the movement of the mounting frame 3.

[0028] In some embodiments, a positioning member 19 is further provided on the side of the mounting frame 3 close to the processing equipment. The positioning member 19 includes a connecting rod 20 rotatably arranged on the mounting frame 3. A baffle 21 is vertically arranged at the bottom of the connecting rod 20. The baffle 21 can limit the movement of the fire door to prevent the fire door from sliding out of the conveyor belt 2. A connecting block is provided on the side of the baffle 21 close to the conveyor belt. A second electric push rod 34 is hinged on the mounting plate 9. The ejection end of the second electric push rod 34 is hinged to the connecting block. The second electric push rod 34 can be extended and retracted to drive the block around the connecting rod. The rod 20 rotates, and a boss 23 is also provided on the baffle 21. The boss 23 extends to one side of the conveyor belt. The boss 23 is relative to the horizontal position of the conveyor belt. When the fire door abuts against the baffle 21, the boss 23 can abut the bottom of the fire door to support the fire door during movement. When the fire door is sent into the processing equipment, the baffle 21 is driven to rotate by pushing the second electric push rod 34, thereby releasing the restriction on the fire door and releasing the clamping of the first vacuum suction cup 6 to place the fire door into the processing equipment.

[0029] In some embodiments, a plurality of detection blocks 31 are arranged horizontally on the frame 1, and an infrared sensor is arranged on the side of the mounting frame 3 close to the detection block 31. The two detection blocks 31 in the middle are close to each other, and the spacing between the detection blocks 31 gradually increases from the middle to both sides. When the mounting frame 3 moves, the moving speed of the mounting frame 3 is detected by the infrared sensor through the detection blocks 31 with different spacings. When the moving speed exceeds the specified value, the infrared sensor transmits an electrical signal to the motor 13 to slow down the mounting frame 3 to prevent unstable clamping due to excessive speed.
