Description

Technical Field

[0001] This invention relates to the field of leather processing, and more specifically to a fully automatic leather cutting device. Background Technology

[0002] As is widely known, leather laser cutting is a process that uses laser technology to precisely cut leather materials. This method has several advantages, such as high cutting precision, smooth edges, and no burrs, making it suitable for various complex designs and patterns. Laser cutting equipment can handle leather of various thicknesses and types and is widely used in the clothing, footwear, bags, and handicrafts industries. To improve leather cutting efficiency, existing leather laser cutting machines use multiple laser heads to cut the leather simultaneously.

[0003] For example, the Chinese patent document with authorization announcement number CN104818350B, announcement date of 2017-09-29, and titled "Fully Automatic Leather Printing and Cutting Machine and its Printing and Cutting Method," includes a frame, with a material rack and a material rack shaft at the front end of the frame. The material rack shaft is mounted on the material rack. Specifically, it also includes an automatic correction mechanism, an automatic feeding robot, an automatic laser cutting mechanism, an automatic printing mechanism, and a control system. The automatic correction mechanism is located at the front end of the frame, while the automatic feeding robot, automatic laser cutting mechanism, and automatic printing mechanism are all mounted on the frame. The control system is located inside the frame and connected to the automatic feeding robot, automatic laser cutting mechanism, and automatic printing mechanism. This invention can truly realize the replacement of manual labor with machinery in production, significantly improving the processing efficiency and accuracy of leather, and reducing processing costs. Furthermore, the printing mechanism, through a computer control system, can accurately print graphics of any shape, effectively solving the problem of asymmetrical graphic printing in existing leather processing processes.

[0004] The shortcomings of the existing technology mentioned above are that, in order to adapt to leather of different target sizes, it is necessary to adjust the distance between each laser head (that is, when the target size is small, the distance between each laser head is small, and when the target size is large, the distance between each laser head is large). The existing adjustment method is to adjust the distance of each laser head one by one and then fix them one by one, which is a rather cumbersome operation process. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic leather cutting device to overcome the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A fully automatic leather cutting device includes a frame and a dual-axis moving mechanism mounted on the frame, wherein a laser cutting component is mounted on the dual-axis moving mechanism;

[0008] The laser cutting assembly includes a sliding base and a plurality of laser heads disposed on the sliding base. The sliding base includes multiple segments that are slidably connected to each other, and the plurality of laser heads are respectively disposed on the multiple segments of the sliding base.

[0009] It also includes a first power component, which, when moving one of the sliding blocks, simultaneously moves the other blocks by a multiple of the distance.

[0012] The aforementioned fully automatic leather cutting device includes a transmission component comprising a first toothed plate fixed to the first segment, a second toothed plate disposed on the third segment, and a gear rotatably disposed on the second segment, the gear meshing with both the first toothed plate and the second toothed plate simultaneously.

[0013] The aforementioned fully automatic leather cutting device includes a cylinder having a first state for driving the second segment to move and a second state disconnected from the second segment.

[0014] It also includes a locking component that fixes the position of the second segment when the cylinder is in the second state.

[0015] The aforementioned fully automatic leather cutting device includes a locking component comprising a card plate, a mounting plate fixedly connected to the second section, and a locking block slidably disposed on the mounting plate;

[0016] The locking block has a first position that is inserted into the card plate and a second position that is away from the card plate. The mounting plate is provided with a second power component for driving the locking block to switch between the first position and the second position.

[0017] In the aforementioned fully automatic leather cutting device, the second power component includes a transmission block fixed to the cylinder, a through hole for the transmission block to pass through on the mounting plate, a first unlocking part on the locking block located on the movement stroke of the transmission block, and a first spring between the locking block and the mounting plate.

[0021] In the above technical solution, the fully automatic leather cutting device provided by the present invention, when adjusting the distance between the laser heads, drives one section of the sliding seat through the first power component, which in turn drives the other sections to move synchronously by a multiple of the adaptive distance, thereby driving the multiple laser heads to move synchronously by a multiple of the adaptive distance, so that the distance between the multiple laser heads can be adjusted synchronously.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] In the description of this invention, it should be understood that... Figure 5 The position of the central movable groove 20 relative to the third segment 303 is left, and vice versa. The terms "center", "length", "width", "degree", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0037] Reference Figure 1-10 This invention provides a fully automatic leather cutting device, including a frame 1 and a dual-axis moving mechanism 2 mounted on the frame 1. The dual-axis moving mechanism 2 is equipped with a laser cutting component. The laser cutting component includes a sliding seat 3 and multiple laser heads 4 mounted on the sliding seat 3. The sliding seat 3 includes multiple segments that are slidably connected to each other, and the multiple laser heads 4 are respectively mounted on the multiple segments of the sliding seat 3. It also includes a first power component, which, when driving one segment of the sliding seat 3 to move, simultaneously drives the other segments to move by a multiple of the distance.

[0038] Specifically, the frame 1 has a frame-type structure with an area for placing leather on top. The dual-axis (i.e., horizontal X-axis and Y-axis) moving mechanism consists of two linear reciprocating drive components arranged perpendicularly to each other on a horizontal plane. The sliding seat 3 is mounted on the dual-axis moving mechanism 2, which can move the sliding seat 3 to any position above the frame 1. The laser cutting component is preferably a laser head 4, and both the laser head 4 and the frame 1 are equipped with optical components 27. The laser head 4 is placed on the sliding seat 3, and a pattern designed by software is used. The dual-axis moving mechanism 2 drives the laser cutting component to move according to the shape of the pattern, thereby cutting off the leather of the complete pattern to complete the cutting of a single piece of leather. Multiple laser heads 4 can be equidistantly arranged on the sliding seat 3. In order to connect with the optical components 27, the multiple laser heads 4 are staggered in the vertical direction. Multiple laser heads 4 cut the leather simultaneously, improving the cutting efficiency. Furthermore, by adjusting the spacing of the laser heads 4, leather patterns of different sizes can be cut. (See the patent document with authorization announcement number CN104818350B for details). This is prior art and will not be elaborated here. However, when adjusting the spacing of multiple laser heads 4, it is necessary to adjust and fix them one by one, which is quite troublesome. One of the core innovations of this invention is that the sliding seat 3 is set into multiple segments, and multiple laser heads 4 are respectively arranged on multiple segments of the sliding seat 3, with the spacing between adjacent laser heads 4 being the same. The first power component can be multiple electric push rods, which are respectively connected to multiple segments of the sliding seat 3. The purpose of this arrangement is that when adjusting the distance between adjacent laser heads 4, when one segment of the sliding seat 3 is driven by the first power component, the other multiple segments will be driven to move synchronously by an adaptive multiple distance, thereby driving multiple laser heads 4 to move synchronously by an adaptive multiple distance, so that the distance between multiple laser heads 4 can be adjusted synchronously. Moreover, when the spacing of the laser heads 4 is reduced, the overall length of the sliding seat 3 will also be shortened, thereby reducing the horizontal space occupied by the sliding seat 3.

[0039] Preferably, the sliding seat 3 includes a first segment 301 slidably disposed on the dual-axis moving mechanism 2, a second segment 302 slidably disposed on the first segment 301, and a third segment 303 slidably disposed on the second segment 302. Specifically, the sliding seat 3 includes three segments slidably connected to each other. Guide rails 5 are provided on both the first segment 301 and the second segment 302. The second segment 302 is slidably connected to the guide rail 5 on the first segment 301, and the third segment 303 is slidably connected to the guide rail 5 on the second segment 302. Preferably, there are three corresponding laser heads 4, which are respectively disposed on the three segments of the sliding seat 3. By controlling the second segment 302 and the third segment 303 to slide on the guide rails 5, the distance between the three laser heads 4 can be adjusted.

[0040] As an alternative to the aforementioned multiple electric actuators controlling multiple segments of the sliding seat 3, preferably, the first power assembly includes a cylinder 6 fixedly connected to the first segment 301, the output end of the cylinder 6 being connected to the second segment 302, and a transmission component being provided between the first segment 301 and the third segment 303. The transmission component includes a first toothed plate 7 fixedly connected to the first segment 301, a second toothed plate 8 provided on the third segment 303, and a gear 9 rotatably provided on the second segment 302, the gear 9 meshing with both the first toothed plate 7 and the second toothed plate 8. Specifically, cylinder 6 is fixed to the side wall of the first section 301, and the side wall of the second section 302 has a protruding part to which cylinder 6 is connected. Extensions are provided on the sides of the first section 301 and the third section 303. A first toothed plate 7 and a second toothed plate 8 are respectively disposed on the two extensions. Gear 9 is rotatably mounted on the side wall of the second section 302. The first toothed plate 7 and the second toothed plate 8 are respectively disposed on the upper and lower sides of gear 9 and simultaneously mesh with gear 9. This arrangement serves to adjust… When adjusting the spacing between the laser heads 4, cylinder 6 is activated. Cylinder 6 drives the second segment 302 to slide along the guide rail 5, thereby adjusting the distance between the laser head 4 on the second segment 302 and the laser head 4 on the first segment 301. Because gear 9 meshes with the first toothed plate 7, gear 9 moves horizontally while rotating. Because gear 9 meshes with the second toothed plate 8, the horizontal movement of gear 9 causes the third segment 303 to move the same distance as the second segment 302. Furthermore, because gear 9 itself rotates, it also... The third segment 303 moves the same distance as the second segment 302. That is, during this process, the distance that the third segment 303 moves relative to the first segment 301 is twice the distance that the second segment 302 moves relative to the first segment 301. Similarly, when the second segment 302 moves in the opposite direction, the distance that the third segment 303 moves relative to the first segment 301 is twice the distance that the second segment 302 moves relative to the first segment 301. This allows the position of the other laser heads 4 to be adjusted synchronously when adjusting the position of a single laser head 4, so that the spacing between the three laser heads 4 remains consistent. (For example, when the horizontal distance between two adjacent laser heads 4 is 20cm, when the second segment 302 moves 10cm toward the first segment 301, the third segment 303 will move 20cm toward the first segment 301. At this time, the distance between the laser head 4 on the first segment 301 and the laser head 4 on the second segment 302 is 10cm, and the distance between the laser head 4 on the third segment 303 and the laser head 4 on the second segment 302 is also 10cm.)

[0041] The above-mentioned method of adjusting the distance between each laser head 4 by directly connecting the cylinder 6 to the second segment 302 requires that the cylinder 6 must be continuously under force. On the one hand, this can easily damage the cylinder 6. On the other hand, when the cylinder 6 is de-energized, it cannot provide support force, which can easily cause the second segment 302 and the third segment 303 to slide freely. To solve the above problems, as another embodiment of the present invention, the cylinder 6 has a first state for driving the second segment 302 to move and a second state disconnected from the second segment 302; it also includes a locking component, which fixes the position of the second segment 302 when the cylinder 6 is in the second state. Specifically, the locking component can be a structure such as a pin. When the position of the laser head 4 needs to be adjusted, the cylinder 6 is connected to the second section 302. At this time, the extension and retraction of the output end of the cylinder 6 can drive the second section 302 to move synchronously to achieve the adjustment. After the adjustment is completed, the cylinder 6 is disconnected from the second section 302. At this time, the position of the second section 302 is fixed by the locking component, and the third section 303 is synchronously fixed by the action of the gear 9 and the second toothed plate 8. At this time, the cylinder 6 does not need to work continuously, so the problem mentioned above will not exist.

[0042] Preferably, the locking assembly includes a locking plate 10, a mounting plate 11 is fixedly connected to the second segment 302, and a locking block 12 is slidably disposed on the mounting plate 11; the locking block 12 has a first position that is inserted into the locking plate 10 and a second position that is away from the locking plate 10, and the mounting plate 11 is provided with a second power assembly for driving the locking block 12 to switch between the first position and the second position. Specifically, the locking plate 10 is set on the side of the first segment 301, and it is a structure composed of multiple teeth. The mounting plate 11 is L-shaped, and its end is fixed to the side of the second segment 302. The locking block 12 is U-shaped and is slidably arranged along the width of the mounting plate 11. The size of one end of the locking block 12 is adapted to the tooth gap. The second power component can also be an existing linear reciprocating drive structure such as an electric push rod. The purpose of this arrangement is that when the cylinder 6 is in the first state, the locking block 12 is in the second position. At this time, the extension and retraction of the output end of the cylinder 6 can drive the second segment 302 and the third segment 303 to move horizontally. When the cylinder 6 is in the second state, the second power component drives the locking block 12 to switch from the second position to the first position. At this time, the position of the second segment 302 can be locked. At this time, the output end of the cylinder 6 can be disconnected from the second segment 302, thus realizing the protection of the cylinder 6.

[0043] Preferably, the second power assembly includes a transmission block 13 fixed to the cylinder 6. The mounting plate 11 has a through hole 14 through which the transmission block 13 can pass. The locking block 12 has a first unlocking part 15 located on the travel stroke of the transmission block 13. A first spring 16 is provided between the locking block 12 and the mounting plate 11. Specifically, the transmission block 13 is preferably a square plate-shaped structure, smaller than the through hole 14. The first unlocking part 15 is a wedge-shaped structure provided on the inner wall of the locking block 12. One end of the first spring 16 is fixed to the inner wall of the locking block 12, and the other end is fixed to the mounting plate 11. The first unlocking part 15 is located on the travel stroke of the transmission block 13 when it moves to the left. This arrangement ensures that when the cylinder 6 is not in operation, the transmission block 13 is located inside the through hole 14, meaning that the transmission block 13 is far from the first unlocking part 15. When it is necessary to adjust the laser head 4 to the left... The output end of the control cylinder 6 extends, thereby causing the transmission block 13 to slide to the left. At this time, the transmission block 13 abuts against the first unlocking part 15, causing the locking block 12 to move away from the latch plate 10, passively switching the locking block 12 from the first position to the second position and storing force on the first spring 16. At this time, the output end of the cylinder 6 continues to extend, and under the action of the transmission block 13 abutting against the first unlocking part 15, it will cause the locking block 12 to continue to move to the left. Since the locking block 12 is slidably arranged along the width direction of the mounting plate 11, it will drive the mounting plate 16 to move further to the left. Plate 11 moves synchronously, thereby driving the second segment 302 and the third segment 303 to move synchronously, so as to adjust the distance between the laser head 4. After the adjustment is completed, the output end of cylinder 6 retracts a small distance, so that the transmission block 13 moves away from the first unlocking part 15. At this time, the elastic force of the first spring 16 is released, so as to drive the locking block 12 to move in the opposite direction, so that its end is inserted into the gap between the plates 10, so as to passively switch the locking block 12 from the second position to the first position. That is, the extension and retraction of the output end of cylinder 6 has the following stroke: First, drive the locking block 12 from the first position 10 to the first position 2. First, the position is passively switched to the second position to unlock the second segment 302. Second, the second segment 302 and the third segment 303 are driven to move horizontally to provide the force required for the adjustment of the laser head 4. Third, after the position of the laser head 4 is switched, the transmission block 13 is controlled to move in the opposite direction to disconnect it from the second segment 302, thus achieving a self-protection function. Fourth, the elastic force of the first spring 16 is released so that the locking block 12 is inserted into the card plate 10, and the position of the second segment 302 and the third segment 303 is passively locked through the transmission assembly.

[0044] Furthermore, the locking block 12 is also provided with a second unlocking part 17, which is also located on the movement stroke of the transmission block 13. Specifically, the second unlocking part 17 is also a wedge-shaped structure provided on the inner side wall of the locking block 12, and is symmetrically arranged with the first unlocking part 15. The second unlocking part 17 is located on the stroke of the transmission block 13 when it moves to the left. The purpose of this arrangement is that when the laser head 4 needs to be adjusted to the right, the output end of the cylinder 6 retracts, which causes the transmission block 13 to abut against the second unlocking part 17. This also causes the locking block 12 to passively switch from the first position to the second position and store force on the first spring 16. After the adjustment is completed, the cylinder 6 controls the transmission block 13 to move away from the second unlocking part 17. At this time, the elastic force of the first spring 16 is released to passively switch the locking block 12 from the second position to the first position, thereby locking the positions of the second segment 302 and the third segment 303.

[0045] It should be noted that, regarding the contact between the transmission block 13 and the first unlocking part 15, since the first unlocking part 15 is a wedge-shaped surface, the transmission block 13 will always provide a horizontal component force to the locking block 12 through the wedge-shaped surface, making the position of the locking block 12 not precise enough. Preferably, the locking block 12 is provided with a flat part 18, which is located on the movement stroke of the transmission block 13. Specifically, there are two flat parts 18, and the two flat parts 18 are symmetrically arranged on the inner sidewall of the locking block 12. They are also located on the movement stroke of the transmission block 13 and behind the first unlocking part 15. The purpose of this arrangement is that when the transmission block 13 contacts the first unlocking part 15 to switch the locking block 12 from the first position to the second position, the locking block 12 will move away from the first unlocking part 15 and insert into the position of the flat part 18. Since the flat part 18 is a plane in the length direction of the sliding seat 3, it will not provide a horizontal reaction force to the locking block 12, thereby improving the accuracy of the movement of the locking block 12.

[0046] In another embodiment of the present invention, the locking plate 10 is slidably disposed on the first segment 301, and a second spring 19 is disposed between the locking plate 10 and the first segment 301. Specifically, a movable groove 20 is provided inside the first segment 301, the locking plate 10 is slidably disposed in the movable groove 20, one end of the second spring 19 is fixedly connected to the locking plate 10, and the other end is fixedly connected to the inner wall of the movable groove 20. The stiffness coefficient of the second spring 19 is less than that of the first spring 16. The gap opening end of the teeth on the locking plate 10 is provided with a left inclined surface 21 and a right inclined surface 22. The advantage of this arrangement is that, firstly, the left inclined surface 21 and the right inclined surface 22 make the size of the gap opening end larger than its internal size. The cylinder 6 is designed to allow the locking block 12 to engage with the locking plate 10. Secondly, when the output end of the cylinder 6 extends to move the locking block 12 to the left, it will abut against the left inclined surface 21. This will cause the locking plate 10 to slide into the movable groove 20 and store force on the second spring 19. After the locking block 12 abuts against the left inclined surface 21, the second spring 19 stores force to automatically reset the locking plate 10, thus avoiding obstruction. This process repeats to allow the locking block 12 to move normally to the left. When the fixed block 12 moves to the target position, the locking block 12 will continue to move a certain distance due to inertia. At this time, the end of the locking block 12 will abut against the left inclined surface 21 to block the locking block 12 and eliminate the leftward force on the locking block 12 due to inertia. Similarly, the right inclined surface 22 can eliminate the rightward force on the locking block 12 due to inertia. After the laser head 4 has finished adjusting to the left, the side of the transmission block 13 will still abut against the flat part 18, and in the first Under the action of the spring force 16, friction will be generated between the side of the transmission block 13 and the flat part 18, making it impossible for the transmission block 13 to disengage properly from the flat part 18. At this time, when the output end of the cylinder 6 retracts, it will drive the locking block 12 to move synchronously, causing the end of the locking block 12 to abut against the right inclined surface 22 to block the locking block 12, so that the locking block 12 will not continue to move with the transmission block 13, thereby eliminating the misalignment caused by the friction between the transmission block 13 and the flat part 18.

[0047] The optical components 27 on the laser head 4 need to be kept clean. If there are impurities on its surface, the laser will burn the impurities during the laser's passage, which can easily damage the optical components 27. Furthermore, the movable groove 20 is provided with multiple air guide holes 23. The first section 301, the second section 302 and the third section 303 are all provided with air outlet pipes 24. A connecting pipe 25 is provided between the air guide holes 23 and the air outlet pipes 24. Specifically, the card plate 10 is slidably sealed to the movable groove 20. Three air vents 23 are preferably located on the side wall of the movable groove 20. Three air outlet pipes 24 are also provided, each connected to an air vent 23 via a connecting pipe 25. The lens of the optical component 27 is located on the extension line of the outlet of the air outlet pipe 24. The outlet end of the air outlet pipe 24 can be equipped with a dustproof structure such as a filter. The connecting pipe 25 is a flexible tube, and the second section 302 and the third section 303 have internal clearance grooves 26 for bending the connecting pipe 25. This arrangement ensures that when the distance between the laser heads 4 is adjusted, the locking block 12 abuts against the inclined surface of the opening end of the card plate 10, cooperating with the first... The second spring 19 allows the clamping plate 10 to move repeatedly. As the clamping plate 10 slides into the movable groove 20, it compresses the gas inside the movable groove 20 and blows the gas through the air guide hole 23, connecting pipe 25, and air outlet pipe 24 onto the lens of the optical component 27 (the blown-away impurities are sucked away by the dust collection component under the frame 1), thereby passively cleaning the lens to improve its cleanliness. When the clamping plate 10 slides out of the movable groove 20 under the elastic force of the second spring 19, the movable groove 20 is refilled with gas for the next cleaning. During the suction process of the movable groove 20, the filter screen can block impurities outside the air outlet pipe 24.

[0048] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
