[0060] The maze assembly line of the smoke detector of the present application is suitable for assembling Figure 1 The labyrinth assembly shown includes a labyrinth body 10, a dustproof net 20 and a labyrinth cover 30. Figure 2 As shown, a maze assembly line for a smoke detector according to one embodiment of the present invention includes a first feeding mechanism 100, an insect net forming mechanism 200, a stamping mechanism 300, a second feeding mechanism 400, and a gripping mechanism 500. The first feeding mechanism 100 is used to transport the maze body to a designated location. The insect net forming mechanism 200 is located on one side of the first feeding mechanism 100. The dust net forming mechanism 200 is used to prepare the dust net and attach it to the maze body. The stamping mechanism 300 is located on one side of the insect net forming mechanism 200 and is equipped with a stamping station 310 for receiving the maze body with the dust net attached. The second feeding mechanism 400 is used to transport the maze cover to a designated location. The grabbing mechanism 500 is disposed between the punching mechanism 300 and the second feeding mechanism 400 and is used to grab the labyrinth cover and buckle the labyrinth cover onto the labyrinth body on the punching position 310 so that the punching mechanism 300 can press and fix the labyrinth cover onto the labyrinth body to form a labyrinth assembly.

[0061] A possible structure of the first feeding mechanism 100 may include a feeding component 110 and a feeding conveyor line 120. The feeding conveyor line 120 is used to connect the feeding component 110, the dust screen forming mechanism 200, and the stamping mechanism 300. Specifically, the feeding conveyor line 120 can receive the labyrinth from the feeding component 110, transport the labyrinth to the dust screen forming mechanism 200 to complete the installation of the dust screen, and then transport the labyrinth with the dust screen installed to the grasping path of the grasping mechanism 500.

[0062] Among them, the loading component 110 can adopt various forms. For example, the loading component 110 includes a lifting structure for lifting a pallet equipped with a maze body, and a translational grasping structure for grabbing the maze body on the pallet and placing the maze body on the loading conveyor line 120. As long as the pallet equipped with the maze body can be transported to the specified position and the maze body can be placed on the loading conveyor line 120, it will be sufficient.

[0063] A possible structure of the second loading mechanism 400 may include a lifting structure, a translational gripping structure, and a transfer line 410. The lifting structure is used to lift a pallet equipped with a labyrinth cover, and the translational gripping structure is used to grip the labyrinth cover on the pallet and place it on the transfer line 410. The transfer line 410 is located on the gripping path of the gripping mechanism 500, facilitating the gripping mechanism 500 to grip the labyrinth cover.

[0064] The stamping mechanism 300 can adopt an existing stamping machine, and the stamping mechanism 300 can be provided with a stamping position 310. In the present application, there is no specific limitation on the number of stamping positions 310 provided for the stamping mechanism 300. The stamping mechanism 300 can be provided with one, two or more stamping positions 310. The labyrinth body provided with a dustproof net can be grabbed and placed on the stamping position 310 by the grabbing mechanism 500. The grabbing mechanism 500 can also grab the labyrinth cover and buckle the labyrinth cover on the labyrinth body located on the stamping position 310, after which the stamping mechanism 300 can perform a stamping step to press the labyrinth cover tightly and securely on the labyrinth body. The grabbing mechanism 500 can adopt an existing robotic arm structure, and the grabbing mechanism 500 can grab two or more labyrinth bodies or labyrinth covers at a time.

[0065] Preferably, the stamping mechanism 300 further includes a second visual inspection unit 320 disposed at the stamping station 310. The second visual inspection unit 320 is used to inspect whether the labyrinth body, equipped with a dust screen, is in place and whether the labyrinth cover is securely fastened. The second visual inspection unit 320 allows for inspection of the assembly of the labyrinth body and the labyrinth cover, thereby improving assembly accuracy on the assembly line.

[0066] The maze assembly line for a smoke detector according to an embodiment of the present application automatically loads the maze body through a first loading mechanism 100, prepares a dust net and attaches it to the maze body using an insect net forming mechanism 200, and automatically loads a maze cover through a second loading mechanism 400. The maze cover is then snapped onto the maze body with the dust net using a gripping mechanism 500, and then the maze cover is pressed and secured to the maze body with the dust net using a stamping mechanism 300. This maze assembly line for a smoke detector can automatically load the maze body and the cover, prepare and form the dust net, and automatically assemble the maze body, dust net, and cover, achieving fully automated maze assembly for smoke detectors, significantly improving assembly efficiency for the smoke detector maze and saving significant manpower and time.

[0067] The insect-proof net forming mechanism 200 of the present application is mainly used to prepare a dust-proof net and to fit the dust-proof net onto a labyrinth body.

[0068] See also Figure 3 and Figure 4 The dust screen forming mechanism 200 includes a mounting frame 210 arranged on one side of the material tray 40, and a feeding part 220, a shearing part 230, a rounding part 240, a welding part 250 and a sleeve part 260 arranged on the mounting frame 210.

[0069] See also Figure 3 The feed section 220 is used to drive one end of the dust screen material forward. One feasible structure of the feed section 220 may include: the feed section 220 includes at least one set of roller pairs 221 arranged in opposition to each other, wherein each roller pair 221 includes two drive rollers that rotate synchronously in opposite directions. The two drive rollers are used to clamp the end of the dust screen material to drive the end of the dust screen material forward. Furthermore, the feed section 220 may also include multiple tensioning rollers 222 disposed between the material tray 40 and the roller pairs 221. The multiple tensioning rollers 222 are used to adjust the tension of the dust screen material.

[0070] See also Figure 3 The shearing section 230 is located downstream of the feeding section 220 and is used to cut the dustproof net material into dustproof net segments of predetermined lengths. The shearing section 230 can have various specific structures, such as electric shears or a cylinder-driven cutter.

[0071] See also Figure 3The rounding portion 240 is located downstream of the shearing portion 230 and is used to arrange the dust screen segment into a circular ring shape. A feasible structure of the rounding portion 240 may be: the rounding portion 240 includes a round seat 241 and a round pressing block 242, and the round seat 241 is rotatably arranged on the mounting frame 210. The round pressing block 242 is arranged on the circumference of the round seat 241, and the round pressing block 242 can press the dust screen segment onto the round seat 241 so that the dust screen segment forms a circular ring shape as the round seat 241 rotates. There may be multiple round pressing blocks 242, and the multiple round pressing blocks 242 may be evenly distributed on the circumference of the round seat 241.

[0072] See also Figure 3 , the welding portion 250 is located on one side of the rounding portion 240, and the welding portion 250 is used to weld the two ends of the annular dustproof net segment to form a dustproof net. The welding portion 250 in the present application can adopt a laser welding head. Preferably, the welding portion 250 is movably arranged on the mounting bracket, and when the rounding portion 240 rounds the dustproof net segment, the welding portion 250 can be moved to a position farther away from the rounding portion 240 to avoid interfering with the rounding process. When the rounding portion 240 completes the rounding of the dustproof net segment, the welding portion 250 can be moved to a position closer to the rounding portion 240, so that the welding portion 250 can perform welding operations on the two ends of the annular dustproof net segment.

[0073] See also Figure 4 The fitting portion 260 is used to fit the dust screen onto the labyrinth. One possible configuration of the fitting portion 260 may include a lower sliding post 261, a clamping assembly 262, and a first drive source 263. A through hole is provided on the mounting frame 210 corresponding to the circular seat 241. One end of the lower sliding post 261 is connected to the circular seat 241, and the other end extends through the through hole to above the first loading mechanism 100. The lower sliding post 261 is used to lower the dust screen from the circular seat 241 to a position near the first loading mechanism 100. The clamping assembly 262 is located on one side of the first loading mechanism 100 and is used to clamp the dust screen that has fallen to the end of the lower sliding post 261 away from the circular seat 241. The first drive source 263 is drivably connected to the clamping assembly 262, driving the clamping assembly 262 to reciprocate between the lower sliding post 261 and the first loading mechanism 100 to press the dust screen onto the labyrinth. The first driving source 263 may be a cylinder or an electric push rod.

[0074] In this example, after the annular dust screen segments on the full-circular seat 241 are welded to form a dust screen, the dust screen can be lowered along the lower slide post 261 to a position close to the first loading mechanism 100 (e.g., the loading conveyor line 120). The dust screen lands at the lower end of the lower slide post 261, precisely opposite the labyrinth at a designated location on the loading conveyor line 120. After the dust screen has fallen into place, the clamping assembly 262 clamps the dust screen and, driven by the first drive source 263, moves it toward the loading conveyor line 120, ultimately securing the dust screen to the labyrinth.

[0075] Preferably, the dust screen forming mechanism 200 further includes a first visual inspection unit 280 disposed on one side of the mounting unit 260. The first visual inspection unit 280 is used to inspect whether the dust screen is properly mounted on the labyrinth. The provision of the first visual inspection unit 280 allows for inspection of the mounting of the dust screen, thereby improving assembly accuracy on the assembly line.

[0076] The structure of the clamping assembly 262 may be as follows: the clamping assembly 262 includes a clamping cylinder and two clamping blocks arranged opposite to each other, and the clamping cylinder is used to drive the two clamping blocks to move closer to or away from each other to clamp the dust screen.

[0077] To facilitate the smooth lifting and lowering of the welded dust screen from the circular seat 241, the dust screen forming mechanism 200 further includes a second drive source 270 and an ejector 271. The ejector 271 is mounted on the mounting frame 210 and positioned above the circular seat 240. The second drive source 270 is in driving connection with the ejector 271 to move the ejector 271 toward the circular seat 240, thereby pushing the welded dust screen off the circular seat 240 and onto the lower slide post 261. The second drive source 270 may be a pneumatic cylinder or an electric push rod.

[0078] See also Figure 3 The ejector portion 271 may include a mounting plate connected to the second driving source 270 and a plurality of ejector rods connected to the mounting plate. The lower end of each ejector rod is used to abut against the welded dust screen to push the dust screen away from the circular portion 240 and into the lower sliding column 261.

[0079] See also Figure 2 Based on the above embodiments, the assembly line further includes a blanking mechanism 600 disposed on one side of the stamping mechanism 300. The blanking mechanism 600 is configured to receive the maze assembly and blank the maze assembly onto a pallet. A possible structure of the blanking mechanism 600 may include a blanking conveyor line and a blanking grabbing structure. In this example, the blanking conveyor line receives the maze assembly stamped by the stamping mechanism 300 and conveys the maze assembly to the blanking grabbing structure, where the blanking grabbing structure can grasp the maze assembly and place it onto a finished product pallet.

[0080] It is worth noting that, to improve the overall structural compactness of the assembly line, the unloading gripping structure and the aforementioned translational gripping structure of the loading component 110 can share a common structure. That is, the translational gripping structure of the loading component 110 can perform the operation of grabbing the maze on the pallet and placing it on the loading conveyor line 120 during some time periods, and can perform the operation of grabbing the maze assembly and placing it on the finished product pallet during other time periods.

[0081] In the present application, there are various ways to transfer the maze assembly from the stamping station 310 to the blanking mechanism 600. For example, a gripping robot can be used to grab the maze assembly on the stamping station 310 and transfer the maze assembly to the blanking mechanism 600. Alternatively, the stamping station 310 of the stamping mechanism 300 can be flipped upside down. After the stamping is completed to form the maze assembly, the stamping station 310 is flipped upside down to place the maze assembly upside down on the receiving end of the blanking mechanism 600.

[0082] The working process of the maze assembly line of the smoke detector according to the embodiment of the present invention is roughly as follows:

[0083] 1. The AGV carrying the pallet containing the labyrinthine structure moves to the first loading mechanism 100. The lifting structure of the loading unit 110 then lowers to dock with the AGV, allowing it to receive the pallet containing the labyrinthine structure. The lifting structure of the loading unit 110 then lifts the pallet to a higher position, allowing the translating gripping mechanism of the loading unit 110 to grasp the labyrinthine structure and place it onto the loading conveyor line 120. The loading conveyor line 120 then transports the labyrinthine structure to the insect screen forming mechanism 200, where it remains in its current position.

[0084] 2. The insect-proof net forming mechanism 200 processes the dust-proof net material. That is, the dust-proof net material is driven by the feeding part 220 and cut into dust-proof net segments of predetermined length by the shearing part 230. The dust-proof net segments are rounded at the rounding part 240. Then, the welding part 250 welds the two ends of the circular dust-proof net segment to form a dust-proof net. The dust-proof net is then put on the labyrinth body located on the feeding conveyor line 120 through the putting part 260.

[0085] 3. The AGV carrying the pallet containing the labyrinth cover moves to the second loading mechanism 400. The lifting structure of the second loading mechanism 400 then lowers to dock with the AGV, allowing it to receive the pallet containing the labyrinth cover. The lifting structure of the second loading mechanism 400 then raises the pallet to a higher position, allowing the second loading mechanism 400's translational grasping mechanism to grasp the labyrinth cover and place it on the transfer line 410.

[0086] 4. The gripping mechanism 500 grabs the labyrinth body with the dust screen from the loading conveyor line 120 and places it on the stamping station 310. The gripping mechanism 500 then grabs the labyrinth cover from the transfer line 410 and snaps the labyrinth cover onto the labyrinth body on the stamping station 310. The stamping mechanism 300 then performs a stamping step to press the labyrinth cover onto the labyrinth body, thereby forming a labyrinth assembly.

[0087] 5. Use the unloading conveyor line and unloading grabbing structure of the unloading mechanism 600 to unload the maze assembly onto a tray.

[0088] 6. The above steps are continuously repeated until a batch of materials is finished.

[0089] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
