[0023] Example 1 like Figure 1-5 An automated slotting device for door frame motherboards, comprising: The system comprises a frame 1, a conveying assembly 2, a pushing assembly 3, an automatic grooving assembly 4, a positioning assembly 5, and a controller 6 (PLC control system). The frame 1, serving as the main supporting structure, adopts a cuboid frame structure. Four adjustable support legs 101 are installed at the bottom of the frame 1 to ensure the structural strength and stability of the entire device. The conveying assembly 2 is mounted on the upper surface of the frame 1. The pushing assembly 3 is mounted above the conveying assembly 2. The automatic grooving assembly 4 is mounted on both sides of the conveying assembly 2. The positioning assembly 5 is mounted above the conveying assembly 2, close to the automatic grooving assembly 4. The controller 6 is mounted on the outer wall of the frame 1 and is electrically connected to the conveying assembly 2, the pushing assembly 3, the automatic grooving assembly 4, and the positioning assembly 5.

[0024] The conveying assembly 2 includes a first electric conveyor roller 201, a first motor 2011, a transverse conveying mechanism 202, a second electric conveyor roller 203, a second motor 2031, and a baffle 204. The first electric conveyor roller 201 and the second electric conveyor roller 203 are mounted on the frame 1 at both ends via bearing seats, and are arranged side-by-side on the left and right sides of the frame 1 along the conveying direction. The first electric conveyor roller 201 and the second electric conveyor roller 203 realize the longitudinal conveying of the door cover main board on the conveying assembly 2, conveying the door cover main board from the starting position to the grooving station or the next process. The transverse conveying mechanism 202 is cross-shaped between the first electric conveyor roller 201 and the second electric conveyor roller 203. The output shaft of the first motor 2011 is connected to the first electric conveyor roller 201 via a coupling, and the output shaft of the second motor 2031 is connected to the second electric conveyor roller 203 via a coupling. The first motor 2011 and the second motor 2031 provide power to the first electric conveyor roller 201 and the second electric conveyor roller 203 respectively, drive the conveyor rollers to rotate, control the conveying speed and conveying direction of the door frame main board, and ensure that the door frame main board is accurately conveyed according to the predetermined path and speed.

[0025] Baffles 204 are symmetrically arranged on both sides of the conveying component 2 to limit the lateral movement range of the door frame main board during the conveying process, prevent the door frame main board from slipping off the conveying component 2 or shifting, and ensure the stability and accuracy of the door frame main board during the conveying process.

[0026] The transverse transmission mechanism 202 includes three identical conveyor belts 2021, a first connecting plate 2022, a connecting rod 2023, and an electric lifting platform 2024. One end of each conveyor belt 2021 is crossed between the first electric conveyor rollers 201, and the other end is crossed between the second electric conveyor rollers 203, forming a transverse transmission path. When the door frame main board needs to be adjusted in position or moved laterally, the conveyor belts 2021 operate, driving the door frame main board to move laterally, realizing the transmission of the door frame main board from one slotted position to the other. A first connecting plate 2022 is symmetrically arranged on both sides of each conveyor belt 2021. The upper end of the first connecting plate 2022 is fixedly connected to one side of the conveyor belt 2021 by bolts, and the lower end is fixedly connected to the lifting end of the electric lifting platform 2024, which is fixedly mounted on the frame 1. Two first connecting plates 2022 are connected by a connecting rod 2023. The electric lifting platform 2024 controls the lifting of its lifting end, which drives the first connecting plate 2022 and the conveyor belt 2021 to move up and down, thereby adjusting the height of the conveyor belt 2021 and enabling the door frame main board to start conveying along the horizontal path.

[0027] The pushing assembly 3 includes an electric push rod 301, a third motor 302, a reverse screw 303, a slider 304, a first fixed plate 305, a second fixed plate 306, a first rotating roller 307, a second rotating roller 308, a third fixed plate 309, and a fourth fixed plate 310. The first fixed plate 305 and the second fixed plate 306 are bolted to both sides of the conveying assembly 2. The two ends of the reverse screw 303 are respectively mounted on the first fixed plate 305 and the second fixed plate 306 via bearings. The third motor 302 is fixedly mounted on the first fixed plate 305, and its output shaft is connected to one end of the reverse screw 303. One end of the slider 304 is connected to the reverse screw 303 via a threaded hole, and the other end of the slider 304 is fixedly connected to the fixed end of the electric push rod 301. When the reverse screw 303 rotates, the slider 304 moves axially along the reverse screw 303 under the action of threaded transmission, thereby driving the electric push rod 301 connected to the slider 304 to move laterally.

[0028] The telescopic end of the electric push rod 301 is fixed with a third fixed plate 309 and a fourth fixed plate 310 that are perpendicular to each other, for contacting and pushing the door frame main board. A first rotating roller 307 and a second rotating roller 308 are respectively mounted on the third fixed plate 309 and the fourth fixed plate 310; these reduce friction between the push rod and the main board, making the pushing process smoother and preventing damage to the surface of the main board. When the slider 304 moves the electric push rod 301 to a designated position, the telescopic end of the electric push rod 301 extends or retracts, pushing the third fixed plate 309 and the fourth fixed plate 310, thereby pushing the main board of the door frame onto the conveying assembly 2.

[0029] The automatic grooving assembly 4 includes a cutting blade 401, a second connecting plate 402, a first electric telescopic rod 403, a rotating shaft 404, a clamping mechanism 405, a cylinder 406, a driving air source 4061, a U-shaped bracket 407, and a fifth motor 408. Two identical U-shaped brackets 407 are symmetrically mounted on both sides of the frame 1, serving as the support frame for the automatic grooving assembly and providing a stable support structure for the grooving operation. The two ends of the second connecting plate 402 are slidably connected to the inner sidewalls of the U-shaped brackets 407. The driving air source 4061 is fixedly mounted on the upper sidewall of the U-shaped bracket 407 via a mounting base. The upper end of the cylinder 406 is connected to the output end of the driving air source 4061, and the telescopic end of the cylinder 406 is connected to the upper part of the second connecting plate 402. Vertical slots 4071 are provided on the inner sidewalls of both ends of the U-shaped bracket 407, and locking blocks 4021 matching the slots 4071 are provided on both sides of the second connecting plate 402. When in operation, the drive air source 4061 is started, and the cylinder 406 extends or retracts, causing the second connecting plate 402 to slide up and down along the slot 4071, which in turn causes the first electric telescopic rod 403, the rotating shaft 404 and the cutting blade 401 to move up and down, thereby adjusting the position of the cutting blade 401 in the vertical direction to determine the depth and position of the groove.

[0030] Two first electric telescopic rods 403 are fixedly mounted side-by-side on the outside of the second connecting plate 402 via a bracket. The two ends of a rotating shaft 404 are respectively connected to the telescopic pins of the two first electric telescopic rods 403. When grooving is required, the telescopic ends of the first electric telescopic rods 403 extend or retract, pushing the rotating shaft 404 to move horizontally, thereby moving the cutting blade 401 closer to or further away from the door frame main board, controlling the depth of the groove made by the cutting blade 401 on the door frame main board, and completing the grooving operation. The rotating shaft 404 passes through the cutting blade 401 and is fixedly connected. A clamping mechanism 405 is located on the outer wall of the U-shaped bracket 407. The output shaft of the fifth motor 408 is connected to the rotating shaft 404 and is fixedly mounted at the lower end of the first electric telescopic rods 403. The fifth motor 408 provides rotational power to the rotating shaft 404 and the cutting blade 401, controlling the rotational speed and direction of the cutting blade 401 to ensure that the cutting blade 401 can perform grooving operations on the door frame main board at a suitable speed, ensuring the efficiency and effectiveness of the grooving.

[0031] The clamping mechanism 405 includes a second electric telescopic rod 4051, a support rod 4052, and a fourth motor 4053. One end of the support rod 4052 is vertically mounted on the outer wall of the U-shaped bracket 407 by bolts. The fourth motor 4053 is mounted on the lower side wall of the support rod 4052, and the upper end of the second electric telescopic rod 4051 is connected to the output end of the fourth motor 4053. The lower end of the second electric telescopic rod 4051 is connected to a clamping block. During operation, the fourth motor 4053 is started, the telescopic end of the second electric telescopic rod 4051 extends, pushing the clamping block downward to press the door frame main board onto the conveying assembly 2, preventing the door frame main board from moving or shaking due to cutting force during grooving, thus ensuring the accuracy and stability of grooving.

[0032] The positioning component 5 includes two high-precision laser sensors 501, which are mounted on the conveying component 2 on the side near the automatic grooving component 4 via brackets, and are used to detect the position of the door frame main board.

[0033] The working process of this utility model is as follows: The main board of the door frame to be slotted is conveyed to the starting end of the conveying assembly 2 and limited by the baffle 204. The controller 6 starts the first motor 2011, which conveys the main board of the door frame longitudinally towards the slotting station through the first electric conveyor roller 201. When the main board of the door frame approaches the automatic slotting assembly 4, the laser sensor 501 detects its position and feeds it back to the controller 6. The controller 6 fine-tunes the conveying speed by adjusting the rotation speed of the first motor 2011, so that the main board of the door frame accurately reaches the slotting station. Controller 6 activates the drive air source 4061, cylinder 406 drives the second connecting plate 402 to slide down, and the fourth motor 4053 drives the second electric telescopic rod 4051 to push the clamping block to press the door frame main board. At the same time, the first electric telescopic rod 403 extends and drives the cutting blade 401 to approach the door frame main board. The fifth motor 408 drives the cutting blade 401 to rotate at high speed. Controller 6 controls cylinder 406 and the first electric telescopic rod 403 to adjust the vertical height and feed speed of the cutting blade 401 to slot one side of the door frame main board. After slotting, controller 6 controls cylinder 406 to drive the clamping mechanism 405 to rise and release the door frame main board. When the door frame main board is transferred to the conveyor belt 2021, the electric lifting platform 2024 is activated to raise the conveyor belt 2021. The door frame main board is transported from one side of the frame 1 to the other side. The electric lifting platform 2024 is controlled to lower the conveyor belt 2021 so that the height is level with the second electric conveyor roller 203.

[0034] If only one side of the door frame main board needs to be slotted, the second motor 2031 is started, and the door frame main board is longitudinally conveyed to the next process via the second electric conveyor roller 203.

[0035] If grooving on the other side needs to continue, the third motor 302 is activated to drive the reverse screw 303 to rotate, causing the slider 304 and the electric push rod 301 to move laterally. This aligns the third fixing plate 309 and the fourth fixing plate 310 of the electric push rod 301 with the position to be pushed onto the main board of the door frame. The electric push rod 301 extends and pushes the main board of the door frame close to the other side wall through the first rotating roller 307 and the second rotating roller 308. After the main board of the door frame is conveyed to the grooving station on the other side along the second electric conveyor roller 203, the positioning component 5 checks the position again, the clamping mechanism 405 clamps the main board of the door frame again, and the cutting blade 401 repeats the grooving operation on the other side according to the preset parameters. After grooving on both sides is completed, the clamping mechanism 405 is released, and the main board of the door frame continues to be conveyed to the next process. The transmission of new main boards of the door frame continues, and the device operates in a cycle.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
