Description

Technical Field

[0001] This invention relates to the field of elevator car door manufacturing, and more particularly to a smart production line for elevator car door production. Background Technology

[0002] The dimensions of each elevator car door are different. In the current production process, the plates are cut by cutting components to fit the dimensions of the car door. However, the size of the plates at the end is too small and does not meet the production requirements. However, these plates can be used for other car door panels, resulting in material waste. Secondly, the production of elevator car doors requires punching holes of different sizes in the sheet metal, which requires multiple processes or frequent switching of punches, resulting in low work efficiency. Finally, in the current equipment manufacturing process, the boards are stacked together, which means that different sizes of boards are mixed together. This means that when workers need to retrieve the boards, they have to remove the ones on top before they can take out the ones below. At the same time, boards that are placed horizontally are prone to deformation. Summary of the Invention

The assembly line body is equipped with intelligent storage equipment in the third section, which is used to collect and transport the boards.

[0019] Specifically, automatic shearing and receiving machines include; Transportation platform 1 is used to transport the sheet metal. The rotary pushing mechanism 2 is slidably mounted on the transport platform 1 and is used to rotate and push the plate. The cutting mechanism 3 is used to cut the plate material pushed by the rotating pushing mechanism 2; The gripping mechanism 4 is used to transport the sheet material cut by the cutting mechanism 3.

[0020] This application places the sheet material on a transport platform, then pushes it to the cutting mechanism via a rotating push mechanism to cut it to the required size. Next, the material that meets the size requirement is transported to the next workstation via the assembly line behind the equipment. Finally, the sheet material that does not meet the size requirement is transported to another workstation by a gripping mechanism for use in the manufacture of other car doors, thereby avoiding material waste.

[0021] Since the edges of the board may not be flush, this application also uses a rotating pushing mechanism to rotate the board, thereby cutting the edges first to make them flush, and then starting the dimensional cutting process.

[0022] In this embodiment, the rotary pushing mechanism 2 includes: The bracket 21 is provided with a pressure rod driver 22, which is used to drive the pressure rod 23 to press the plate onto the transport platform 1; The rotating pressure plate 25 is mounted on the bracket 21 and located below the pressure rod 23. It is used to support the bottom of the plate and can rotate the plate when it is rotated.

[0023] In an embodiment of this application, the pressure rod driver is placed in parallel and has a slider at one end. The slider is connected to a hinge arm, which is hinged to the bracket. The other end of the hinge arm is hinged to the pressure rod. When the driver advances, one end of the hinge arm presses down, thereby driving the pressure rod to move down to press the plate onto the platform.

[0025] First, the second cylinder drives the trolley to move upward, thus creating space for the plate to rotate. Since the pressure rod and the rotating pressure plate work together to grip the plate, the rotating pressure plate can drive the plate to rotate, so that each edge of the plate can be sliced ​​by the cutting mechanism. Finally, the first cylinder pushes the clamping plate to clamp the plate and push it to the cutting mechanism for cutting.

[0026] In this embodiment, an adjustment mechanism is also included for adjusting the cutting mechanism 3.

[0027] Specifically, the adjustment mechanism includes: The second eccentric wheel 5 is rotatably mounted on the frame, and the second eccentric wheel 5 is connected to the outer wheel 51 that contacts the cutting mechanism 3.

[0028] When the second eccentric wheel rotates, its eccentric position pushes the cutter to shift, thereby adjusting the tool clearance.

[0029] Furthermore, the adjustment mechanism also includes; The drive gear 52 is connected to the second eccentric wheel 5; The drive shaft 53 has a second driver 54 at one end and a first gear 55 that meshes with the drive gear 52 at the other end.

[0030] This embodiment features automatic adjustment. The driver can be a servo motor. Under the action of the servo motor, the gear drives the fan-shaped drive teeth to rotate, thereby driving the second eccentric wheel to rotate for tool gap adjustment. This embodiment has higher adjustment accuracy.

[0031] In this embodiment, the adjustment mechanism further includes; Roller 56 is disposed on the other side of the second eccentric wheel 5, and roller 56 is provided with a disc spring 57 connected to the frame.

[0032] During adjustment, the cutter pushes the roller to press the disc spring. After the second eccentric wheel has passed through, the disc spring returns to its original position and pushes the cutter back to its original position.

[0033] In this embodiment, a waste bin 6 located below the cutting mechanism 3 is also included. The waste bin is pushed into a collection trolley, and the collected waste is transported by the trolley.

The vertical shaft 42 is provided with a slider 43 that can move along its direction. The slider 43 is provided with a gripping frame 44. The gripping frame 44 is provided with a plurality of suction cups 45 for picking up the sheet material.

[0035] Specifically, the crossbeam drives the gripping mechanism to move, then the slider moves down to make the suction cup hold the unsuitable size board tightly, and then the crossbeam continues to move outward so that the suction cup can carry the board to another work station.

[0036] In this embodiment, the crossbeam 41 is also provided with a main drive 46. The main drive 46 has a linkage shaft 47 at both ends. The linkage shaft 47 has a drive wheel 48 inside. The drive wheel 48 meshes with the rack 49 in the frame. The main drive simultaneously drives the drive wheels at both ends to rotate, and the rotating wheel can drive the crossbeam to move along the rack.

[0037] Specifically, a stamping device with automatic punch switching includes; Transport line 201 is used for transporting sheet metal; A stamping machine includes a frame 202, a drive device 203 is provided inside the frame 202, the drive device 203 is connected to a pressure plate assembly 204, the drive device 203 is used to drive the pressure plate assembly 204 to move downward, the lower side of the pressure plate assembly 204 is provided with a plurality of slide grooves 205, each slide groove 205 is provided with a striking block 206, and the striking block 206 is connected to a pushing mechanism 207; It also includes a punch plate 208 disposed within the frame 202, the punch plate 208 having a plurality of punches 209 of different sizes relative to the striking block 206.

[0038] This application uses a transport line to transport sheet metal to a stamping equipment for punching. Then, according to the required size, a pushing mechanism pushes the striking block to the corresponding punch. Finally, a drive device drives a pressure plate, which in turn drives the corresponding punch to punch the sheet metal. By repeating this process, different punching processes can be performed on the sheet metal, thereby improving production efficiency.

[0039] In this embodiment, the punches 209 have at least two rows, and the pushing mechanism is preferably a cylinder. Each cylinder corresponds to one striking block, and one striking block corresponds to two punches. The cylinder pushes the striking block to the corresponding punch.

[0040] In this embodiment, the driving device 203 includes; The second drive motor 210 is connected to the second gear 211; The second gear 211 is driven by a bearing 212, the bearing 212 is connected to a first eccentric wheel 213, and the first eccentric wheel 213 is connected to a connecting rod 214.

[0041] The connecting rod is a figure-eight shaped connecting rod. The driver drives the gear, which in turn drives the bearing to rotate. The bearing is inserted into the eccentric position of the first eccentric wheel through a plug, and then performs a reciprocating oscillating motion, which causes the connecting rod to move up and down, thereby driving the pressure plate assembly to move down.

[0042] In this embodiment, the frame 202 is further provided with a sliding mechanism that is limitedly connected to the pressure plate assembly 204.

[0043] Preferably, the sliding mechanism includes; A sliding seat 215 is mounted on the frame 202; A sliding block 216 is connected to the pressure plate assembly 204.

The sliding seat is provided with a sliding groove according to the swing path of the connecting rod to ensure that the pressure plate assembly can move up and down smoothly. The sliding seat 215 is provided with a sliding groove.

[0044] In this embodiment, a tension spring 217 is provided between the driving device 203 and the pressure plate assembly 204.

[0045] In this embodiment, the punch 209 is provided with a plurality of return springs 218.

[0046] Specifically, intelligent warehousing equipment used for retrieving elevator car door panels includes; The robotic arm body has a frame 300 at its end, and the frame 300 has a plurality of clamping mechanisms 301 in the vertical direction for vertically clamping the plate. It also includes a storage bracket 302 surrounding the outer periphery of the robotic arm body, the storage bracket 302 having a plurality of cavities 303 for accommodating the plate.

[0047] This application uses a clamping mechanism to clamp multiple different boards and then place them into a storage rack with multiple cavities, thereby classifying the different boards. When retrieving materials, the corresponding boards can also be clamped by the clamping structure and transported. Therefore, not only will the boards not be damaged, but materials can also be retrieved according to actual needs.

[0048] In this embodiment, the robotic arm body includes; The first connecting arm 304 is connected to the frame 300; The first drive motor 305 is connected to the first connecting arm 304 and is used to drive the first connecting arm 304 to rotate.

[0049] By rotating the first drive motor, the first connecting arm is rotated so that the frame can be laid horizontally or placed horizontally. When transported from the transport line, it needs to be laid horizontally for clamping, and then placed vertically in the warehouse so that each board is corresponding and placed vertically in the warehouse.

[0050] In this embodiment, the robotic arm body further includes; The second connecting arm 306 is rotatably connected to the first connecting arm 304 at its end; A first driver 307 is connected to the second connecting arm 306 and is used to drive the first connecting arm 304 to rotate relative to the second connecting arm 306 so that the frame 300 is raised or lowered.

[0051] This allows the clamping mechanism to move up and down according to the actual situation to remove the corresponding sheet material.

[0052] In this embodiment, the robotic arm body further includes; A connecting bracket 308 is rotatably connected at its end to the second connecting arm 306; The third driver 309 is connected to the connecting bracket 308 and is used to drive the second connecting arm 306 to swing back and forth.

[0053] The second connecting arm swings under the rotation of the third driver, thereby moving the clamping mechanism closer to or further away from the cavity to achieve different functions.

[0054] In this embodiment, the connecting bracket 308 is further provided with a damping cylinder 310 connected to the second connecting arm 306.

[0055] In this embodiment, the robotic arm body further includes a base 311, and the connecting bracket 308 is rotatably mounted on the base 311. The base 311 is provided with a fourth driver 312 for driving the connecting bracket 308 to rotate.

[0056] This allows the clamping mechanism to rotate relative to the center of the equipment, enabling material to be retrieved from different storage racks and to face the input and output transport lines.

The clamping bracket 316 is provided with a clamping part 318.

[0058] After the drive cylinder is activated, the first slider is moved upward, which in turn causes the articulated arm to swing. Finally, the two frames move inward through the second slider, causing the clamping part to perform a clamping action.
