DETAILED DESCRIPTION

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] The purpose of the present invention is to provide a linked reciprocating conveying device for magnetic steel, a laser engraving system and method to solve the problems existing in the above-mentioned prior art, greatly improve the efficiency of arranging the placement of magnetic steel during laser engraving, and prepare for subsequent batch laser engraving.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1-8 As shown, this embodiment provides a linked reciprocating conveying device for magnetic steel, including a linked reciprocating feeding device, the linked reciprocating feeding device including:

[0044] Automatic feeding device, which is connected with the discharge track, can realize the feeding of magnetic steel;

[0045] The dovetail slide rail device includes a plurality of linked dovetail sliders 62. The dovetail sliders 62 are provided with a collection area 623 for placing magnetic steel. The collection areas 623 of the plurality of dovetail sliders 62 can be connected in sequence, and the collection area 623 at the leftmost end can be connected to the discharge track.

[0046] The induction area 626 is provided on the rightmost collecting area 623 and can sense the magnetic steel. The induction area 626 can be provided with an induction device such as an induction switch to sense the magnetic steel.

[0047] A driving device, which is connected to the dovetail slide rail device and can drive a plurality of dovetail sliders 62 to move back and forth in a coordinated manner;

[0048] The controller is used to control the above-mentioned devices and realize automatic operation.

[0049] In this embodiment, the magnetic steel is preferably a square magnetic steel 10, or magnetic steel of other shapes can be selected; wherein, the shapes of the collecting area 623 and the discharge track are adaptively designed according to the shape of the magnetic steel.

[0050] In this embodiment, the automatic feeding device includes a vibrating disk 1, and the discharging track includes a first discharging track 11; an electromagnet is provided in the vibrating disk 1, and a spiral track is provided on the inner wall of the vibrating disk 1, and the top of the spiral track is connected to the feed port of the first discharging track 11. The vibrating disk 1 vibrates through the electromagnet to arrange and transport the magnets in an orderly manner, and is sent to the discharging port of the first discharging track 11 along the spiral track, and the square magnets 10 are oriented and neatly arranged along the first discharging track 11.

[0051] In this embodiment, the automatic feeding device further includes a straight vibration track 2, and the discharging track further includes a second discharging track 21. The feeding port of the straight vibration track 2 is connected to the discharging port of the first discharging track 11, and the discharging port of the straight vibration track 2 is connected to the feeding port of the second discharging track 21. After the square magnetic steel 10 enters the straight vibration track 2, it continues to be transported forward;

[0052] Among them, the cross-sectional shape of the straight vibration track 2 is convex, which can not only clearly see the conveying of the product, but also prevent the product from stacking during the conveying process.

[0053] In this embodiment, V-shaped guide blocks 625 and V-shaped guide grooves 622 are respectively provided on the left and right side surfaces of the dovetail slider 62. The V-shaped guide blocks 625 can slide freely in the V-shaped guide grooves 622, and the V-shaped guide grooves 622 and V-shaped guide blocks 625 of adjacent dovetail sliders 62 fit tightly with each other; at the same time, the dovetail slider 62 has a two-way limit block, including a first limit block 621 and a second limit block 624. When the dovetail slider 62 is loading, the first limit block 621 plays a linkage and limiting role, and when the dovetail slider 62 returns, the second limit block 624 plays a linkage and limiting role.

[0054] In this embodiment, a collection area 623 for the square magnet 10 is provided above the dovetail slider 62. The length and width of the hole groove in the collection area 623 are designed according to the size of the square magnet 10. The bottom reference surface of the collection area 623 is processed by processing a U-shaped groove and an R-angle of the edges and corners, which reduces the contact area between the magnet and the collection area 623, making it easier for the magnet to be grasped and transferred by the subsequent negative pressure suction cup 87.

[0055] In this embodiment, the driving device adopts a pneumatic device, which includes a linear guide rail and a slider. The slider is slidably installed on the linear guide rail. The slider is connected to the dovetail slider 62 at the rightmost end and can drive the dovetail slider 62 at the rightmost end to move; the front end and the rear end of the linear guide rail are respectively provided with a first limiting column 52 and a second limiting column 53, which can limit the slider; the slider is also connected to the cylinder 4.

[0056] In this embodiment, the cylinder 4 has a bidirectional sealing structure, and the reciprocating motion of the cylinder 4 can drive the linked reciprocating motion of the dovetail slide rail device.

[0057] In this embodiment, when the cylinder 4 of the pneumatic device is in the initial state, the slider is at the first limit column 52 position, which is the initial position state. At this time, the several dovetail sliders 62 of the dovetail slide rail device are also in the initial state; the slots of the collection area 623 of the several dovetail sliders 62 are arranged in parallel in a straight line and abut against the second discharge track 21. The bottom surfaces of the two tracks are on the same reference plane. The square magnet 10 in the straight vibration track 2 can freely enter the collection area 623 of the dovetail slider 62 and continue to be transported forward along the edges of the several collection areas 623 until the square magnet 10 reaches the induction area 626 of the last collection area 623.

[0058] In this embodiment, when the sensing area 626 detects the square magnetic steel 10, it transmits a signal to the controller, and the controller controls the straight vibration track 2 and the vibration plate 1 to stop vibrating to stop conveying the square magnetic steel 10. After a delay of a few seconds, the cylinder 4 will start to push out the piston rod 44. Since the piston rod 44 abuts against the slider on the linear guide, the slider and the dovetail slider 62 move together in the direction away from the cylinder 4, and move as far as the second limit column 53. During this process, the dovetail slider 62 at the far right end will drive the adjacent dovetail sliders 62 to move forward from right to left in sequence due to the setting of the first limit block 621 of its structure. At this time, the square magnetic steel 10 in the collection area 623 of several dovetail sliders 62 will also move forward until the linear guide slider moves to the second limit column 53, and the dovetail slider 62 also stops moving.

[0059] In this embodiment, the stroke of the single-piece dovetail slider 62 is set to the width of a square magnet 10, and the distance between the first limit column 52 and the second limit column 53 is the total stroke of the slider on the linear guide rail, which is set to the number of square magnets 10 transmitted x the width of a single square magnet 10, thereby realizing automatic loading and positioning arrangement of the square magnets 10, and improving the efficiency of placing the square magnets 10 before laser engraving.

[0060] This embodiment also discloses a laser engraving system including the aforementioned linked reciprocating conveying device for magnetic steel, and also includes a laser engraving machine capable of engraving the arranged magnetic steel. Specifically, the laser engraving machine includes a column 71, a lifting shaft 72, and a laser source 73. The lifting shaft 72 is rotatably mounted on the column 71. The laser source 73 is connected to the lifting shaft 72 via a mounting bracket (similar to a screw-nut substructure). A handle is mounted on the top of the lifting shaft 72. Rotating the handle can drive the lifting shaft 72 to rotate, thereby driving the laser source 73 to move up and down. After the square magnetic steel 10 is arranged in position by the several collection areas 623 of the dovetail slide device, the laser engraving machine will start the laser engraving program to engrave patterns or text at specific locations.

[0061] In this embodiment, the linked reciprocating conveying device of the magnetic steel also includes a unloading mechanism, which includes a rotating cylinder device. The rotating cylinder device includes a rotating cylinder 81, a rotating swing arm 82 and a negative pressure suction cup 87. The rotating swing arm 82 is installed on the rotating cylinder 81. A negative pressure suction cup 87 is provided directly below the rotating swing arm 82. The negative pressure suction cup 87 can be directly opposite to the center of the magnetic steel. The number of negative pressure suction cups 87 corresponds to the number of the collection area 623.

[0062] In this embodiment, the unloading operation of the square magnets 10 is completed by rotating the cylinder 81. During the initial unloading operation, the negative pressure suction cup 87 directly below the rotating swing arm 82 is aligned with the center of each square magnet 10. The clockwise rotation and downward pressure of the rotating cylinder 81 controls the multiple negative pressure suction cups 87 under the rotating swing arm 82 to grab the square magnets 10 that have been laser-engraved in the collection area 623. The rotating swing arm 82 rotates to the designed angle (preferably 90° in this embodiment, with no limit on the angle), and then rotates counterclockwise to transfer the grabbed square magnets 10 to the storage box.

[0063] This embodiment realizes the function of grasping and releasing the square magnet 10 by controlling the inflow and outflow of compressed air from the first air inlet and outlet of the negative pressure suction cup and the second air inlet and outlet of the negative pressure suction cup, and realizes the function of rotating the rotating swing arm 82 of the rotating cylinder 81 to rotate right and press down and rotate left and rise by controlling the inflow and outflow of compressed air from the first air inlet and outlet of the rotating cylinder and the second air inlet and outlet of the rotating cylinder.

[0064] After the rotating cylinder device completes the unloading process, the cylinder 4 retracts the piston rod 44. Since the piston rod 44 is in contact with the slider, the slider and the dovetail slider 62 move together in the direction close to the cylinder 4. The dovetail slider 62 at the rightmost end will drive the adjacent dovetail sliders 62 to move from right to left in sequence due to the second limit block 624 of its structure. The slider moves to the first limit column 52 due to the setting, thereby restoring its initial state.

[0065] At this time, the induction switch in the induction area 626 sends a signal to start the direct vibration track 2. The square magnet 10 in the direct vibration track 2 freely enters the collection area 623 of the dovetail slider 62 and continues to be transported forward along the edges of several collection areas 623 until the square magnet 10 reaches the induction area 626 of the last collection area 623, completing the automatic loading and unloading and laser engraving process of the square magnet 10.

[0066] The above process is repeated repeatedly to complete the laser engraving operation of the square magnetic steel 10 in batches.

[0067] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
