Description

Technical Field

[0001] The invention relates to the field of leather processing, and in particular to a fully automatic leather cutting device. Background Art

[0002] As is known, leather laser cutting is a process that uses laser technology to accurately cut leather materials. This method has many advantages, such as high cutting accuracy, smooth edges, no burrs, and is suitable for various complex designs and patterns. Laser cutting equipment can handle a variety of thicknesses and types of leather and is widely used in clothing, shoes, bags, handicrafts and other industries. In order to improve the cutting efficiency of leather, existing leather laser cutting machines use multiple laser heads to cut leather at the same time.

The existing adjustment method is to adjust the distance of the laser one by one, and then fix them one by one, and the operation process is relatively cumbersome. Summary of the invention

[0035] In order 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 the present invention, it is necessary to understand that Figure 5 The position of the middle movable groove 20 relative to the third section 303 is on the left, and vice versa. The terms "center", "length", "width", "degree", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which 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, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0037] Reference Figure 1-10 A fully automatic leather cutting device provided by an embodiment of the present invention comprises a frame 1 and a two-axis moving mechanism 2 arranged on the frame 1, wherein a laser cutting assembly is arranged on the two-axis moving mechanism 2; the laser cutting assembly comprises a sliding seat 3 and a plurality of laser heads 4 arranged on the sliding seat 3, wherein the sliding seat 3 comprises a plurality of sections slidably connected to each other, and the plurality of laser heads 4 are respectively arranged on the plurality of sections of the sliding seat 3; and further comprises a first power assembly, which is used for synchronously driving the remaining plurality of sections to move an adaptive multiple of the distance when driving one section of the sliding seat 3 to move.

[0038] Specifically, the frame 1 is a frame-type structure with an area for placing leather on the top. The dual-axis (i.e., X-axis and Y-axis in the horizontal direction) moving mechanism is two linear reciprocating drive components arranged perpendicular to each other on the horizontal plane. The sliding seat 3 is arranged on the dual-axis moving mechanism 2. The dual-axis moving mechanism 2 can drive the sliding seat 3 to move to any position above the frame 1. The laser cutting component is preferably a laser head 4, and the laser head 4 and the frame 1 are both provided with an optical component 27. The laser head 4 is placed on the sliding seat 3. A good pattern is designed by software, and the laser cutting component is driven to move according to the shape of the pattern by the dual-axis moving mechanism 2, so that the leather with a complete pattern can be cut off to complete the cutting of a single leather. Multiple laser heads 4 can be equidistantly arranged on the sliding seat 3. In order to connect with the optical component 27, the multiple laser heads 4 are staggered in the vertical direction. The multiple laser heads 4 cut the leather at the same time, which improves the leather cutting efficiency. Leather patterns of different sizes can be cut by adjusting the spacing between the laser heads 4. (For details, see the patent document with authorization announcement number CN104818350B). This is the prior art and will not be elaborated on. However, when adjusting the spacing between multiple laser heads 4, it is necessary to adjust and fix them one by one, which is troublesome. One of the core innovations of the embodiment of the present invention is that the sliding seat 3 is set into multiple sections, and the multiple laser heads 4 are respectively arranged on the multiple sections of the sliding seat 3, and the spacing between adjacent laser heads 4 is the same. The first power component can be multiple electric push rods, and the multiple electric push rods are respectively connected to the multiple sections of the sliding seat 3. The effect of such a setting is that when adjusting the distance between adjacent laser heads 4, when one section of the sliding seat 3 is driven by the first power component, the remaining multiple sections will be synchronously driven to move the adaptive multiple distance synchronously, thereby driving the multiple laser heads 4 to move the adaptive multiple distance synchronously, so that the distance between the multiple laser heads 4 can be adjusted synchronously. Moreover, when the spacing between the laser heads 4 is adjusted to a smaller size, 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 section 301 slidably arranged on the dual-axis moving mechanism 2, a second section 302 slidably arranged on the first section 301, and a third section 303 slidably arranged on the second section 302. Specifically, the sliding seat 3 includes three sections slidably connected to each other, the first section 301 and the second section 302 are both provided with guide rails 5, the second section 302 is slidably connected to the guide rail 5 on the first section 301, and the third section 303 is slidably connected to the guide rail 5 on the second section 302. Preferably, there are three corresponding laser heads 4, and the three laser heads 4 are respectively arranged on the three sections of the sliding seat 3. By controlling the second section 302 and the third section 303 to slide on the guide rail 5, the distance between the three laser heads 4 can be adjusted.

[0040] As an alternative to the above-mentioned multiple electric push rods controlling multiple sections of the sliding seat 3 respectively, preferably, the first power assembly includes a cylinder 6 fixedly connected to the first section 301, the output end of the cylinder 6 is connected to the second section 302, and a transmission member is provided between the first section 301 and the third section 303. The transmission member includes a first toothed plate 7 fixedly connected to the first section 301, a second toothed plate 8 is provided on the third section 303, and a gear 9 is rotatably provided on the second section 302, and the gear 9 is meshed with the first toothed plate 7 and the second toothed plate 8 at the same time. Specifically, the 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 portion, and the cylinder 6 is connected to the portion. The side surfaces of the first section 301 and the third section 303 are provided with extension portions, and the first tooth plate 7 and the second tooth plate 8 are respectively provided on the two extension portions. The gear 9 is rotatably provided on the side wall of the second section 302, and the first tooth plate 7 and the second tooth plate 8 are respectively provided on the upper and lower sides of the gear 9, and mesh with the gear 9 at the same time. The function of such a setting is that when adjusting When the distance between the laser heads 4 is adjusted, the cylinder 6 is started, and the cylinder 6 drives the second section 302 to slide along the guide rail 5 to adjust the distance between the laser head 4 on the second section 302 and the laser head 4 on the first section 301. Because the gear 9 is meshed with the first toothed plate 7, the gear 9 is moved horizontally while rotating. Because the gear 9 is meshed with the second toothed plate 8, the gear 9 moves horizontally and drives the third section 303 to move the same distance as the second section 302. Because the gear 9 rotates itself, it will bring The third section 303 moves the same distance as the second section 302, that is, in this process, the distance the third section 303 moves relative to the first section 301 is twice the distance the second section 302 moves relative to the first section 301. Similarly, when the second section 302 moves in the opposite direction, the distance the third section 303 moves relative to the first section 301 is twice the distance the second section 302 moves relative to the first section 301. In this way, when the position of a single laser head 4 is adjusted, the positions of other laser heads 4 can be adjusted synchronously, so that the spacing between the three laser heads 4 is always consistent (for example, when the horizontal distance between two adjacent laser heads 4 is 20 cm, when the second section 302 moves 10 cm toward the first section 301, the third section 303 will move 20 cm toward the first section 301. At this time, the distance between the laser head 4 on the first section 301 and the laser head 4 on the second section 302 is 10 cm, and the distance between the laser head 4 on the third section 303 and the laser head 4 on the second section 302 is also 10 cm).

[0041] The above-mentioned method of directly connecting the cylinder 6 with the second section 302 to adjust the distance between the laser heads 4 requires that the cylinder 6 must be continuously in a stressed state. On the one hand, it is easy to cause damage to the cylinder 6. On the other hand, when the cylinder 6 is powered off, it cannot provide supporting force, which can easily cause the second section 302 and the third section 303 to slide freely. To solve the above problem, as another embodiment of the present invention, the cylinder 6 has a first state for driving the second section 302 to move and a second state disconnected from the second section 302; it also includes a locking component, and when the cylinder 6 is in the second state, the locking component fixes the position of the second section 302. Specifically, the locking component can be a structure such as a latch. 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 function. When 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 gear plate 8. At this time, the cylinder 6 does not need to act continuously, so the above-mentioned problems will not exist.

[0042] Preferably, the locking assembly includes a card plate 10, a mounting plate 11 is fixedly connected to the second section 302, and a locking block 12 is slidably provided on the mounting plate 11; the locking block 12 has a first position plugged into the card plate 10 and a second position away from the card plate 10, and a second power assembly is provided on the mounting plate 11 for driving the locking block 12 to switch between the first position and the second position. Specifically, the card plate 10 is arranged on the side of the first section 301, which is a structure composed of multiple teeth. The mounting plate 11 is L-shaped, and its end is fixedly connected to the side of the second section 302. The locking block 12 is a U-shaped structure, which is slidably arranged along the width direction of the mounting plate 11, and 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 such a setting is that when the cylinder 6 is in the first state, the locking block 12 is in the second position. At this time, the output end of the cylinder 6 can be extended and retracted to drive the second section 302 and the third section 303 to move horizontally. When the cylinder 6 is in the second state, the locking block 12 is driven by the second power component to switch from the second position to the first position. At this time, the position of the second section 302 can be locked. At this time, the output end of the cylinder 6 can be disconnected from the second section 302, thereby achieving protection of the cylinder 6.

[0043] Preferably, the second power assembly includes a transmission block 13 fixedly connected to the cylinder 6, a through hole 14 is provided on the mounting plate 11 for the transmission block 13 to pass through, a first unlocking portion 15 is provided on the locking block 12, and the first unlocking portion 15 is located on the movement stroke of the transmission block 13, and 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, and its size is smaller than that of the through hole 14. The first unlocking portion 15 is a wedge-shaped structure provided on the inner side wall of the locking block 12. One end of the first spring 16 is fixedly connected to the inner side wall of the locking block 12, and the other end is fixedly connected to the mounting plate 11. The first unlocking portion 15 is located on the stroke when the transmission block 13 moves to the left. The effect of such a setting is that when the cylinder 6 is not operating, the transmission block 13 is located inside the through hole 14, that is, at this time, the transmission block 13 is far away from the first unlocking portion 15. When it is necessary to adjust the laser head 4 to the left, The output end of the control cylinder 6 is extended, thereby driving the transmission block 13 to slide to the left. At this time, the transmission block 13 will abut against the first unlocking portion 15 to drive the locking block 12 to move away from the card plate 10, so as to passively switch the locking block 12 from the first position to the second position, and store 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 abutment between the transmission block 13 and the first unlocking portion 15, the locking block 12 will continue to move to the left. Because the locking block 12 is arranged to slide along the width direction of the mounting plate 11, it will drive the mounting plate 11 to move to the second position. The plate 11 moves synchronously, thereby driving the second section 302 and the third section 303 to move synchronously, so as to adjust the distance between the laser heads 4. When the adjustment is completed, the output end of the cylinder 6 contracts a small distance, so that the transmission block 13 is separated from the first unlocking portion 15. At this time, the elastic force of the first spring 16 is released to drive the locking block 12 to move in the opposite direction, so that its end is inserted into the gap between the card plates 10, so as to passively switch the locking block 12 from the second position to the first position, that is, the extension and contraction of the output end of the cylinder 6 has the following strokes: first, the locking block 12 is driven from the first unlocking portion 15 to the second unlocking portion 15. First, the position is passively switched to the second position to unlock the second section 302. Second, the second section 302 and the third section 303 are driven to move horizontally to provide the force required for adjusting the laser head 4. Third, after the position switching of the laser head 4 is completed, the transmission block 13 is controlled to move in the opposite direction to disconnect it from the second section 302, thereby realizing the self-protection effect. Fourth, the elastic force of the first spring 16 is released to enable the locking block 12 to be plugged into the card plate 10, and the second section 302 and the third section 303 are passively locked through the transmission assembly.

[0044] Furthermore, the locking block 12 is also provided with a second unlocking portion 17, which is also located on the movement stroke of the transmission block 13. Specifically, the second unlocking portion 17 is also a wedge-shaped structure provided on the inner side wall of the locking block 12, and is arranged symmetrically with the first unlocking portion 15, and the second unlocking portion 17 is located on the stroke when the transmission block 13 moves to the left. The purpose of such a setting is that when the laser head 4 needs to be adjusted to the right, the output end of the cylinder 6 contracts, and the transmission block 13 abuts against the second unlocking portion 17, and the locking block 12 is also passively switched from the first position to the second position, and the first spring 16 is charged. After the adjustment is completed, the cylinder 6 controls the transmission block 13 to move away from the second unlocking portion 17, and the elastic force of the first spring 16 is released, so as to passively switch the locking block 12 from the second position to the first position, so as to lock the positions of the second section 302 and the third section 303.

[0045] It should be noted that, as far as the transmission block 13 abuts against the first unlocking portion 15, since the first unlocking portion 15 is a wedge-shaped surface, the transmission block 13 will always provide a horizontal force component to the locking block 12 through the wedge-shaped surface, so that the position of the movement of the locking block 12 is not accurate enough. Preferably, the locking block 12 is provided with a plane portion 18, and the plane portion 18 is located on the movement stroke of the transmission block 13. Specifically, there are two plane portions 18, and the two plane portions 18 are symmetrically arranged on the inner side wall of the locking block 12, which are also located on the movement stroke of the transmission block 13 and behind the first unlocking portion 15. The effect of such a setting is that when the transmission block 13 abuts against the first unlocking portion 15 to switch the locking block 12 from the first position to the second position, the locking block 12 will be away from the first unlocking portion 15 and inserted into the position of the plane portion 18. Since the plane portion 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, so as to improve the accuracy of the movement of the locking block 12.

[0046] As another embodiment of the present invention, the card plate 10 is slidably disposed on the first section 301, and a second spring 19 is disposed between the card plate 10 and the first section 301. Specifically, a movable groove 20 is provided inside the first section 301, and the card plate 10 is slidably disposed in the movable groove 20. One end of the second spring 19 is fixedly connected to the card 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 smaller than the stiffness coefficient of the first spring 16. The gap opening end of the teeth on the card plate 10 is provided with a left inclined surface 21 and a right inclined surface 22. The advantage of such a configuration is that, firstly, the left inclined surface 21 and the right inclined surface 22 make the size of the gap opening end larger than the size inside thereof. Inch, so that the locking block 12 and the card plate 10 are plugged in. Secondly, when the output end of the cylinder 6 is extended to drive the locking block 12 to move to the left, the locking block 12 will abut against the left inclined surface 21. At this time, the card plate 10 will slide toward the inside of the movable groove 20 and store force on the second spring 19. When the locking block 12 is in contact with the left inclined surface 21, the second spring 19 stores force to achieve automatic reset of the card plate 10 to achieve avoidance, and so on, so that the locking block 12 can move to the left normally. When the lock is When the fixed block 12 moves to the target position, the locking block 12 will continue to move a distance under the action of 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, so as to eliminate the leftward force applied to the locking block 12 due to inertia. Thirdly, similarly, the right inclined surface 22 can eliminate the rightward force applied to the locking block 12 due to inertia. Fourthly, when the laser head 4 is adjusted to the left, the side surface of the transmission block 13 will still abut against the plane portion 18, and in the first Under the action of the elastic force of the spring 16, friction will be generated between the side of the transmission block 13 and the flat portion 18, making it impossible for the transmission block 13 and the flat portion 18 to disengage normally. At this time, when the output end of the cylinder 6 contracts, it will drive the locking block 12 to move synchronously, and the end of the locking block 12 will 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 inaccurate insertion caused by the friction between the transmission block 13 and the flat portion 18.

[0047] The optical component 27 on the laser head 4 needs to be kept clean. If there are impurities on its surface, the laser will burn the impurities during the laser passing through, which may easily damage the optical component 27. Furthermore, a plurality of air guide holes 23 are opened inside the movable groove 20, and air outlet pipes 24 are provided on the first section 301, the second section 302 and the third section 303, and a connecting pipe 25 is provided between the air guide hole 23 and the air outlet pipe 24. Specifically, the card plate 10 is slidably sealed and connected to the movable groove 20, the air guide holes 23 are opened on the side wall of the movable groove 20, and preferably there are three of them, and three air outlet pipes 24 are also provided, and the three air outlet pipes 24 are respectively connected to the air guide holes 23 through three connecting pipes 25, the lens of the optical component 27 is located on the extension line of the outlet of the air outlet pipe 24, and the outlet end of the air outlet pipe 24 can be provided with a dustproof structure such as a filter, the connecting pipe 25 is a hose, and the second section 302 and the third section 303 are provided with an avoidance groove 26 for the connecting pipe 25 to bend. The effect of such a setting is that when the spacing of the laser head 4 is adjusted, the locking block 12 will abut against the inclined surface of the opening end of the card plate 10, cooperating with the first The second spring 19 allows the card plate 10 to move repeatedly. When the card plate 10 slides toward the inside of the movable groove 20, the gas inside the movable groove 20 will be squeezed, and the gas will be blown to the lens of the optical component 27 through the air guide hole 23, the connecting pipe 25 and the air outlet pipe 24 (the blown impurities will be sucked away by the dust collection component under the frame 1), so that the lens can be passively cleaned to improve the cleanliness of the lens. When the card plate 10 slides toward the outside of the movable groove 20 under the action of the elastic force of the second spring 19, the movable groove 20 will be filled with gas again to prepare for the next cleaning, and when the movable groove 20 inhales air, the filter can block impurities outside the air outlet pipe 24.

[0048] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that 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 above 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.
