The utility model provides a cutting device.

In the embodiment of the present invention, as shown in fig. 1, the die cutting device includes a machine table 100, a material frame 200, a die cutting machine 300, a vision inspection assembly 400, and a control device. The material rack 200 is movably installed on the machine table 100, and a feeding track is formed on the material rack 200. The feeder rail is used to transport the material 700 and has a die cutting station 201 (see fig. 2). The die cutting machine 300 is installed on the machine platform 100 and located above the die cutting station 201, and is used for performing die cutting on the material 700. The vision inspection assembly 400 is mounted on the machine 100 for inspecting and feeding back the position of the material 700 to the control device. The control device is electrically connected to the visual inspection assembly 400, and is used for controlling the movement of the material rack 200 according to the feedback of the visual inspection assembly 400, so as to adjust the position of the material 700.

In the visual inspection, a robot is used to replace a human eye for measurement and judgment. The visual detection component is a machine vision product (namely an image shooting device which is divided into a CMOS (complementary metal oxide semiconductor) product and a CCD (charge coupled device) product) which converts a shot target into an image signal, transmits the image signal to a special image processing system, and converts the image signal into a digital signal according to information such as pixel distribution, brightness, color and the like; the image system performs various operations on these signals to extract the characteristics of the target, and then determines the position of the product. In this embodiment, the visual inspection device 400 is a CCD visual inspection device, and in other embodiments, the visual inspection device 400 may also be a CMOS visual inspection device.

According to the above die cutting device, when the material 700 is die cut, the material 700 to be die cut is conveyed to the die cutting station 201 through the feeding rail, and then the material 700 stops moving. At this point, the vision inspection assembly 400 is activated, initiating inspection and feeding back the position of the material 700 to the control device. The control device controls the material rack 200 to move according to the feedback result of the visual inspection assembly 400, and further drives the material 700 on the material rack 200 to move, so as to adjust the position of the material 700 to be die-cut relative to the die-cutting station 201 until the material 700 is accurately positioned at the die-cutting station 201. It is thus clear that, compare with current cutting device, the die cutting device of this application passes through visual detection subassembly 400 and controlling means's collaborative work, realizes the real-time regulation to material 700 position, has replaced the mode of artifical monitoring with the regulation material 700 die cutting precision, greatly improves the automation level of equipment, has reduced artifical the participation to die cutting device's machining efficiency and machining precision have greatly been improved.

Referring to fig. 2, in the present embodiment, the control device includes a driving device, a power end of the driving device is movably connected to the material rack 200, and the power end of the driving device is configured to move along a first direction and a second direction. Wherein the first direction is parallel to the feeding direction of the material 700, and the second direction is perpendicular to the feeding direction of the material 700. Typically, the web 700 is susceptible to deviation from the die-cutting station 201 in the second direction during transport of the web 700. When the die-cut material 700 has a certain flexibility, for example, the electronic product screen protection film (mobile phone film, flat electronic brain film, etc.) is liable to deviate from the die-cutting station 201 in the first direction due to insufficient or excessive internal tension. In many instances, if the material 700 is displaced in both the first and second directions during the movement, the material 700 will be deflected relative to the die cutting station 201. Therefore, by controlling the power end of the driving device to move along the first direction and the second direction, the rack 200 can be driven to move along the first direction and the second direction, so as to adjust the position of the material 700 along the first direction and the second direction. And, by controlling the power end of the driving device to move along the first direction and the second direction at the same time (at this time, the driving device should have at least two power ends capable of moving along the first direction and the second direction), the stack 200 will deflect relative to the die-cutting station 201 under the action of two forces transmitted along the first direction and the second direction, so that the material 700 will deflect to the correct station relative to the die-cutting station 201. Therefore, the die cutting device can adjust the position of the material 700 more accurately to adapt to the processing of different materials 700, and the application range of the die cutting device is widened. Of course, in other embodiments of the present application, the power end of the driving device can drive the material frame 200 to move only in the first direction or the second direction. It should be noted that the present disclosure is not limited thereto, and in some embodiments, the control device can also control the stacks 200 to translate/deflect in any one or any number of directions within the plane of the feeding track.

It should be noted that, in order to receive the position information of the material 700 fed back by the vision assembly, determine whether the material 700 is located at the correct position, and transmit instructions to the driving device, the control device further includes a control system, and details about the structure of the control system are not described herein.

As shown in fig. 3, in the present embodiment, the driving device includes two sets of driving assemblies 500, power ends of the two driving assemblies 500 are rotatably connected to the stack 200, one driving assembly 500 is used for driving the stack 200 to move along a first direction, and the other driving assembly 500 is used for driving the stack 200 to move along a second direction. Therefore, the material rack 200 can move along the first direction and the second direction respectively through the two groups of driving assemblies 500 and deflect relative to the die cutting station 201, and the driving mechanism and the transmission mechanism of the driving device are simple in structure, easy to design and controllable in cost. Of course, in other embodiments, the driving device may also include only one driving assembly 500, and the movement of the stack 200 in the first direction and the second direction, respectively, and the movement in the first direction and the second direction simultaneously can be realized by one driving assembly 500.

Referring to fig. 2 and fig. 3, in the present embodiment, the material frame 200 includes a feeding frame 210, a material receiving frame 220 and a connecting rod 230. Wherein the feeding frame 210 is installed at the feeding side of the die cutting station 201, and a plurality of conveying roller shafts are rotatably arranged on the feeding frame 210 so as to convey the roller shafts. The material receiving frame 220 is installed on the discharging side of the die cutting station 201, and one side of the material receiving frame 220, which is far away from the material feeding frame 210, is provided with a group of conveying clamping rollers which can rotate under the driving of a motor to clamp and convey the material 700. The connecting rod 230 is connected between the feeding frame 210 and the receiving frame 220 and disposed away from the die-cutting station 201. The feeding frame 210, the die cutting station 201 and the material collecting frame 220 all belong to a part of a feeding track. It can be understood that the material rack 200 is provided with the feeding rack 210 and the material receiving rack 220 which are arranged at the interval die cutting station 201, and the feeding rack 210 and the material receiving rack 220 are connected through the connecting rod 230, so that the weight of the material rack 200 can be reduced on the premise of adjusting the position of the material 700, the requirement for the driving force of the driving device is reduced, and the cost control is facilitated. Of course, in other embodiments of the present application, the stack 200 may be integrally disposed.

Further, in order to improve the stability of the connection between the feeding frame 210 and the receiving frame 220, in this embodiment, two connecting rods 230 are provided, and the two connecting rods 230 are connected between the feeding frame 210 and the receiving frame 220 and are respectively disposed at two sides of the die cutting station 201 in the second direction.

Referring to fig. 3 and 4, in order to improve the motion stability of the material frame 200, in the embodiment, the control device includes two driving devices, and the two driving devices are respectively disposed corresponding to the feeding frame 210 and the material receiving frame 220, and are used for driving the feeding frame 210 and the material receiving frame 220 to move simultaneously and in the same direction. Naturally, each drive device comprises two sets of drive assemblies 500. It should be noted that, in other embodiments of the present application, the control device can drive the feeding rack 210 and the receiving rack 220 to move simultaneously only by one driving device.

Since the two driving devices have the same structure, the driving device at the feeding frame 210 is taken as an example in the present application to further explain the driving device.

Referring to fig. 5, in the present embodiment, each driving assembly 500 includes a power element 510 and a supporting base 520. The supporting bases 520 are rotatably connected to the rack 200, one power member 510 is used for driving one supporting base 520 to slide along a first direction, and the other power member 510 is used for driving the other supporting base 520 to slide along a second direction. Thus, the two power members 510 respectively drive the two support bases 520 to slide along the first direction and the second direction, so that the material rack 200 can be simply and conveniently driven. It should be noted that in other embodiments of the present application, the power element 510 can also directly drive the stack 200 to move without passing through the supporting seat 520.

Specifically, in the present embodiment, the power element 510 is a motor, and the motor drives the supporting base 520 to slide through a transmission mechanism 530. It can be understood that the motor as a common power member 510 has the advantages of easy acquisition, mature control method, etc., and the forward rotation and the reverse rotation of the output shaft of the motor can easily realize the reciprocating motion of one support seat 520 along the first direction (the other support seat 520 does the reciprocating motion along the second direction). The transmission mechanism 530 is used for converting the rotation output by the motor into the translation of the support seat 520. It should be noted that the design of the present application is not limited to this, and in other embodiments, the power member 510 may also be a cylinder, a hydraulic cylinder, or the like. The support seat 520 is driven to slide by the movement of the piston rod of the air cylinder or the hydraulic cylinder.

Optionally, in an embodiment of the present application, the motor is one of a servo motor or a stepper motor.

Referring to fig. 5 and fig. 6, in the present embodiment, the motor drives the supporting seat 520 to slide through the screw-slider transmission mechanism 530. Specifically, the lead screw-slider transmission mechanism 530 includes a lead screw 531 and a slider 532. The lead screw 531 is connected to the output end of the motor, one lead screw 531 extends along the first direction, and the other lead screw 531 extends along the second direction. The slider 532 is screwed on the screw 531 and slidably installed on the machine 100 along the extending direction of the screw 531. The supporting base 520 is fixedly mounted on the slider 532. So, when the motor drives the screw 531 to rotate, the slider 532 can slide along the extending direction of the screw 531, thereby driving the supporting seat 520 to move along the first direction and the second direction, and driving the material rack 200. It should be noted that the design of the present application is not limited thereto, and in other embodiments of the present application, the transmission mechanism 530 between the motor and the support seat 520 may also be a rack and pinion transmission mechanism, a crank link transmission mechanism, or the like. In particular, when the driving mechanism 530 is a crank driving mechanism, the specific driving process can be referred to a sewing machine.

As shown in fig. 6, in the embodiment, the machine 100 is provided with two supporting blocks 110 corresponding to the two supporting seats 520, and the supporting blocks 110 are provided with first sliding rails 111. The first slide rail 111 of one of the support blocks 110 extends along a first direction, the second slide block 532 of the other support block 110 extends along a second direction, and the two support bases 520 are slidably mounted on the two first slide rails 111, respectively. It can be understood that, through the arrangement of the supporting block 110, the supporting seat 520 can be provided to provide support so as to share the pressure applied to the slider 532, thereby reducing the burden of the motor and prolonging the service life of the motor. The first slide rail 111 can further limit the moving direction of the supporting base 520, so as to improve the moving stability of the supporting base 520.

With reference to fig. 6, in the present embodiment, the supporting base 520 includes a first base 521 and a second base 522. The first seat 521 is fixedly connected to the sliding block 532 and slidably mounted on the first slide rail 111, a second slide rail 5211 extending in a direction perpendicular to the first slide rail 111 is disposed at the top of the first seat 521, and the second seat 522 is slidably mounted on the second slide rail 5211 and rotatably connected to the rack 200. That is, the first seat 521 can slide along the first slide rail 111, and the second seat 522 can slide along the second slide rail 5211 and can rotate relative to the material rack 200. Thus, when the two power members 510 respectively drive the two supporting bases 520 to move along the first direction and the second direction, the two supporting bases 520 do not interfere with each other.

Referring to fig. 6 and fig. 7, based on the screw slider transmission mechanism 530, the present embodiment further provides that the machine 100 further includes a screw support 120 corresponding to the screw 531 of the screw slider transmission mechanism 530. The lead screw support 120 is provided therein with a bearing, and is sleeved on the lead screw 531 through the bearing. It can be understood that the lead screw support 120 is sleeved on the lead screw 531 through a bearing, and can provide support for the lead screw 531 under the condition of ensuring the free rotation of the lead screw 531, so that the burden on the motor can be reduced.

Further, in the present embodiment, a portion of the screw 531 which is fitted to the bearing is an optical axis. Therefore, the assembling tightness between the screw rod 531 and the bearing can be improved, and the screw rod 531 can more stably support the screw rod 531.

Further, referring to fig. 1 to 3, in order to ensure the stability of the material 700 relative to the material rack 200 when the material rack 200 moves, negative pressure devices 600 are respectively disposed on the feeding rack 210 and the receiving rack 220. The negative pressure device 600 is used for being started when the material 700 moves to the die cutting station 201 to absorb the material 700, and is closed after the die cutting of the material 700 is completed to ensure the normal transportation of the material 700. Of course, in other embodiments, the negative pressure device 600 may not be disposed on the material frame 200.

Further, the machine 100 is further provided with a feeding bracket 140 and a receiving bracket 150 at two sides along the feeding direction of the material 700. The feeding bracket 140 is installed on the feeding side of the machine 100 and has a feeding reel 141, and the receiving bracket 150 is installed on the discharging side of the machine 100 and has a receiving reel 151. The feeding reel 141 and the receiving reel 151 are driven by a motor. The feeding support 140 and the receiving support 150 are mounted on the machine 100, so that the integrity of the machine 100 is improved, and the die cutting of the strip 700 by the die cutting device is facilitated.

Further, in the present embodiment, to facilitate the tensioning of the strip material 700, the feeding reel 141 and the receiving reel 151 are located at different heights.

Further, referring to fig. 3 and 4, the machine 100 further has a surrounding plate 130 disposed around the feeding frame 210 and the receiving frame 220, and the surrounding plate 130 surrounds the feeding frame 210 and the receiving frame 220 to form an installation cavity in cooperation with the machine 100 for installing the driving device. Therefore, the pressing protection can be provided for the driving device, and the appearance is more attractive.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
