Description

Technical Field

[0001] The present invention relates to the technical field of die-cutting detection, and in particular to automatic die-cutting detection equipment. Background Art

[0002] Traditional die-cutting refers to a cutting process used in the post-production of printed materials. This process allows printed materials or other paper products to be cut according to pre-designed patterns using a die-cutting blade, thus expanding the possibilities of printed materials into shapes that are no longer limited to straight edges or right angles. Traditional die-cutting involves using a die-cutting blade, assembled into a die-cutting plate according to the design requirements, and then, under pressure, cutting the printed material or other sheet material into the desired shape or cut.

[0003] After die-cutting is completed, the rolled die-cut parts need to be inspected. The existing inspection equipment consists of a winding mechanism, an unwinding mechanism and a detection mechanism. The winding mechanism pulls and rolls the die-cut parts, the unwinding mechanism unwinds the die-cut parts, and the detection mechanism detects the die-cut parts. However, the pulling of the winding mechanism will cause the die-cut parts to be stressed, and the die-cut parts and waste materials will be deformed and wrinkled after being stressed. The wrinkles will affect the inspection of the die-cut parts, and the deformation will cause the gap between the die-cut parts and the waste materials to become smaller or the overlap will disappear. Then the light emitted by the backlight source cannot penetrate the gap of the die-cut parts, and the edge of the die-cut parts cannot be determined, which will lead to misjudgment.

[0004] To this end, there is an urgent need for an automatic die-cutting detection device to solve the above-mentioned shortcomings; for example, the patent with announcement number CN118794952B discloses an automatic die-cutting detection device, which relates to the field of die-cutting detection technology, including a detection mechanism, the detection mechanism including a detection head and a backlight source, and a workpiece to be tested is installed between the detection head and the backlight source; a relaxation mechanism, which is installed on the detection mechanism and is used to relax the detection section at the top of the workpiece to be tested; a detection section clamping mechanism, which is installed on the top of the relaxation mechanism and is used to clamp the two sides of the workpiece to be tested to form a detection section, and the workpiece to be tested is located between the detection section clamping mechanisms; a wrinkle processing mechanism, which is installed on the detection section clamping mechanism and is used to eliminate wrinkles formed by the stress on the workpiece to be tested; the present invention processes the detection section through the wrinkle processing mechanism, thereby solving the influence of wrinkles on detection, and relaxes the stressed workpiece to be tested through the detection section clamping mechanism and the relaxation mechanism, thereby avoiding deformation of the workpiece to be tested, affecting light transmittance, making the edge of the workpiece to be tested clearer, and avoiding misjudgment.

[0005] However, when using this automatic die-cutting inspection equipment to inspect the workpiece to be tested, it is necessary to clamp the two sides of the workpiece to be tested through the inspection section clamping mechanism to form an inspection section; for this reason, after the inspection section clamping mechanism clamps the two sides of the workpiece to be tested, the entire die-cutting equipment needs to be shut down to ensure that the inspection of the inspection section is completed; for this reason, when the existing automatic die-cutting inspection equipment is inspecting the workpiece to be tested, the entire die-cutting equipment needs to be shut down to ensure that the inspection of the inspection section is completed, which greatly shortens the time for the die-cutting equipment to process the die-cut parts.

[0024] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0025] See also Figure 1-Figure 4 , the embodiment provided by the present invention: an automatic die-cutting detection device, comprising: a frame 1, a detection mechanism 2, a pressing and tensioning mechanism, a pressing and tensioning mechanism and a buffer mechanism 3; the detection mechanism 2 includes a detection head 21 and a light source board 22; the detection head 21 and the light source board 22 are both mounted on the frame 1, and the detection head 21 and the light source board 22 are respectively located on opposite sides of the workpiece to be tested; the pressing and tensioning mechanism is mounted on the frame 1, and the pressing and tensioning mechanism is located on a side of the workpiece to be tested away from the light source board 22, the pressing and tensioning mechanism applies a pressure toward the light source board 22 to the workpiece to be tested, and simultaneously applies a pulling force in multiple directions on the plane of the workpiece to be tested to reduce wrinkles on the workpiece to be tested; The buffer mechanism 3 is arranged on the side of the light source plate 22 close to the unloading of the workpiece to be tested, and the buffer mechanism 3 includes: a conveyor roller 31, a slider 32 and a lower pressure roller 33; the two conveyor rollers 31 are rotatably mounted on the frame 1, and the two conveyor rollers 31 are arranged in the horizontal direction; the lower pressure roller 33 is arranged parallel to the two conveyor rollers 31, and the lower pressure roller 33 is located between the two conveyor rollers 31; the lower pressure roller 33 is mounted on the frame 1 through the slider 32, the lower pressure roller 33 is rotatably connected to the slider 32, and the slider 32 is slidably connected to the frame 1 in the vertical direction; the workpiece to be tested passes around the conveyor roller 31 and the lower pressure roller 33 in the conveying direction in sequence to confine the workpiece to be tested to a V-shaped area.

[0026] During specific implementation, the unwinding mechanism of the die-cutting equipment unwinds the die-cut piece, and after the die-cut piece passes through the buffer mechanism 3, the die-cut piece is reeled by the reeling mechanism of the die-cutting equipment. The unwinding mechanism discharges the die-cut piece so that the die-cut piece moves on the light source plate 22. When the test piece to be tested moves to the top of the light source plate 22, the pressing and tensioning mechanism is controlled to act, and the pressing and tensioning mechanism applies a pressure toward the light source plate 22 to the test piece, and cooperates with the light source plate 22 to clamp the test piece; at the same time, the pressing and tensioning mechanism applies a pressure in multiple directions on the plane of the test piece. The appropriate pulling force is used to reduce the wrinkles on the test piece; then the light source on the light source board 22 and the detection head 21 are started, and the light emitted by the light source board 22 is emitted from the die-cutting gap of the test piece. The detection head 21 obtains the image of the test piece and judges the transmittance of the gap to judge whether the die-cutting is thorough. If it is not thorough, there will be no gap between the die-cut piece and the waste material, and then the die-cut piece and the waste material cannot be separated; while the test piece is being detected, the side of the light source board 22 close to the material of the test piece will be exerted with a pulling force by the winding mechanism. For this reason, under the action of the pulling force, the material will bypass the lower pressure roller 3. The die-cut pieces on the V-shaped area will exert a sliding force on the lower pressing roller 33 to push the lower pressing roller 33 upward, thereby reducing the area of the test piece buffered in the V-shaped area, thereby realizing the buffering function, so that the winding mechanism can continue to rotate without stopping; and the die-cut pieces on one side of the winding mechanism will be accumulated on the side of the light source board 22 away from the buffer mechanism 3; after the detection is completed, the tensioning mechanism is pressed to reset, and the lower pressing roller 33 can slide downward again under the action of gravity to reset, so as to realize the detection of the next test piece; for this reason, by setting the buffer mechanism 3, When inspecting the die-cut parts, it can buffer the pulling force of the winding mechanism, ensure that the winding mechanism and the unwinding mechanism can continue to operate, and thus the die-cutting equipment does not need to stop and wait; and by pressing the setting of the tensioning mechanism, it can apply a pressure toward the light source board 22 to the workpiece to be tested, and cooperate with the light source board 22 to clamp the workpiece to be tested, and apply an appropriate amount of pulling force in multiple directions on the plane of the workpiece to be tested to reduce wrinkles on the workpiece to be tested, thereby ensuring that the light source on the light source board 22 can pass through the gap on the workpiece to be tested, and obtain the image of the light source on the workpiece to be tested through the detection head 21.

[0027] See also Figure 1-Figure 4In other embodiments, the pressing and tensioning mechanism includes: an actuator 4, a pressing plate 5 and a first driving member; the pressing plate 5 is slidably mounted on the frame 1 in the vertical direction, and the first driving member drives the pressing plate 5 to slide; a plurality of actuators 4 are arranged in a circular array; the actuator 4 includes: a mounting frame 41, a driving rack 42, a gear 43, a tensioning rack 44, a pulley 45 and a flat belt 46; the driving rack 42 is vertically arranged, and one end of the driving rack 42 is mounted on the pressing plate 5; the mounting frame 41 is slidably mounted on the driving rack 42 along the length direction of the driving rack 42; the two gears 43 are rotatably mounted on the mounting frame 41, and the line connecting the two is tilted downward. The gear 43 is coaxially fixed with a pulley 45, and the two pulleys 45 are connected by a flat belt 46; the tensioning rack 44 is slidably mounted on the mounting frame 41 in the horizontal direction, and the tensioning rack 44 is engaged with the gear 43 below, and the driving rack 42 is engaged with the rack above; the extension lines of the multiple tensioning racks 44 intersect at the midpoint of the circular array of the multiple actuators 4; further, the actuator 4 also includes a rubber pad 47; the rubber pad 47 is mounted below the tensioning rack 44; the tensioning rack 44 contacts the workpiece to be tested through the rubber pad 47, thereby increasing the friction between the workpiece to be tested and the tensioning rack 44 to effectively prevent relative sliding between the workpiece to be tested and the tensioning rack 44.

[0028] During specific implementation, the first driving member can be a structure that can move back and forth, such as a cylinder, a hydraulic cylinder, an electric push rod, a reciprocating screw, etc. When the first driving member is actuated, the first driving member controls the pressing plate 5 to slide downward, and the pressing plate 5 drives multiple driving racks 42 to move downward, and makes the tensioning rack 44 abut against the upper end surface of the workpiece to be tested; the tensioning rack 44 pushes the workpiece to be tested to abut against the light source board 22, thereby clamping the workpiece to be tested; to this end, the light source board 22 applies a reaction force to the mounting frame 41, so that the driving rack 42 slides on the mounting frame 41, and the driving rack 42 drives the gear 43 to rotate, and the gear 43 drives another gear 43 to rotate through the pulley 45 and the flat belt 46, and the lower gear 43 drives the tensioning rack 44 to move, and the tensioning rack 44 applies a pulling force to the workpiece to be tested, which can effectively reduce the wrinkles on the workpiece to be tested.

[0029] See also Figure 1-Figure 4In other embodiments, the press-tension mechanism further includes a limit assembly 6 ; the limit assembly 6 includes a telescopic member 61 and a connector 62 ; the upper end of the telescopic member 61 is fixedly mounted below the drive rack 42 , and the lower end of the telescopic member 61 is mounted with the connector 62 , which mates with the tooth grooves of the tensioning rack 44 . In a specific implementation, the telescopic member 61 can be a retractable structure such as a hydraulic cylinder, a pneumatic cylinder, or an electric push rod; the drive rack 42 slides downward, and after sliding a certain distance, the connector 62 plugs into the nearest tooth groove on the tensioning rack 44 , thereby limiting the sliding movement of the tensioning rack 44 . By adjusting the length of the telescopic member 61 , the sliding distance of the tensioning rack 44 can be adjusted.

[0030] See also Figure 1-Figure 4 In other embodiments, an adjustment mechanism 7 is further included, which can adjust the distance between the multiple actuators 4 and the midpoint. By setting the adjustment component, the distance between the multiple actuators 4 and the midpoint can be adjusted, so that the pressing and tensioning mechanism can adapt to die-cut parts of different sizes. Furthermore, the adjustment mechanism 7 includes: a hinge plate 71, a connecting plate 72, and a second driving member; the driving rack 42 is slidably mounted on the pressing plate 5, and the extension lines of the sliding directions of the multiple driving racks 42 intersect at the midpoint of the circular array of the multiple actuators 4; the hinge plate 71 corresponds to the driving rack 42 one by one; one end of the hinge plate 71 abuts the driving rack 42, and the other end of the hinge plate 71 is hinged to the connecting plate 72; the second driving member drives the connecting plate 72 to move in the vertical direction.

[0031] In a specific implementation, the second drive member can be a reciprocating structure such as a pneumatic cylinder, a hydraulic cylinder, an electric push rod, or a reciprocating screw. By controlling the movement of the second drive member, the second drive member drives the connecting plate 72 to move vertically, thereby driving the hinge plate 71 to rotate. The hinge plate 71 pushes the drive rack 42 to slide on the pressing plate 5, thereby adjusting the distance between the multiple actuators 4 and the midpoint. Furthermore, avoidance holes are provided in the connecting plate 72 and the pressing plate 5. The provision of the avoidance holes ensures that the detection head 21 can pass through the two avoidance holes to detect the test piece.

[0032] See also Figure 1-Figure 4 In another embodiment, the buffer mechanism 3 further includes: a guide roller 34; the guide roller 34 is rotatably mounted on the frame 1, and the guide roller 34 and the two conveying rollers 31 are located on the same plane, and the guide roller 34 is arranged on the side of the light source board 22 close to the loading of the workpiece to be tested; through the setting of the guide roller 34, it can cooperate with the conveying roller 31, so that the workpiece to be tested is arranged parallel to the light source board 22, and then the pressing and tensioning mechanism can better cooperate with the light source board 22 to achieve clamping of the workpiece to be tested.
