[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figures 1 to 10As shown, an automatic punching and cutting device for automotive trim strips according to the present invention includes: a punching mechanism 1, which has two rotating feeding members 2 and a plurality of punches 3 that reciprocate vertically, wherein the plurality of punches 3 are located between the two rotating feeding members 2 and are evenly arranged horizontally, the two rotating feeding members 2 are used to drive the trim strip to move horizontally, and the plurality of punches 3 are used to punch the moving trim strip; a cutting mechanism 4, which is disposed on the side of the punching mechanism 1, the cutting mechanism 4 has a clamping member 5 that moves horizontally and a cutter 6 that moves vertically, the clamping member 5 is used to clamp the trim strip after punching, and the cutter 6 is used to cut the trim strip; and a storage mechanism 7, which is disposed between the punching mechanism 1 and the cutting mechanism 4, wherein the storage mechanism 7 realizes the storage of the trim strip between the punching mechanism 1 and the cutting mechanism 4, and controls the moving speed of the clamping member 5 on the cutting mechanism 4.

[0020] The automatic punching and cutting device in this solution is installed behind the trim production device. It punches and cuts holes in a whole trim strip after it has been formed. After the trim strip is formed, one end of the trim strip is passed through the punching mechanism 1, the storage mechanism 7, and the cutting mechanism 4 in sequence. During operation, the rotating feeder 2 on the punching mechanism 1 moves the trim strip on the automatic punching and cutting device in this solution. Multiple punches 3, which move back and forth in the vertical direction, impact the entire trim strip, thereby automatically completing the automatic punching operation of the trim strip. Then, the rotating feeder 2 moves the trim strip to the storage mechanism 7, where it is stored... After the trim strip on the feeding mechanism 7 reaches the preset length, the clamping member 5 on the cutting mechanism 4 clamps the end of the trim strip and pulls it onto the cutting mechanism 4. The cutting blade 6 on the cutting mechanism 4 then cuts the trim strip into multiple pieces of the required length. This solution achieves continuous automatic punching and cutting of the trim strip through the cooperation of the rotating feeding member 2, punch 3, cutting blade 6, and clamping member 5. There is no need to transfer the trim strip, saving space in the workshop and accelerating the production efficiency of the trim strip, ultimately reducing the production time and processing cost of the trim strip.

[0021] Furthermore, the punching mechanism 1 includes: a first support frame 8; a first fixed seat 9, which is detachably connected to the first support frame 8; a first motor 10, which is detachably connected to the first fixed seat 9, and the output end of the first motor 10 is provided with a first driving wheel 11; a first driven wheel 12, which is rotatably connected to the first fixed seat 9 and connected to the first driving wheel 11 via a belt 13; a dust cover 14, which is connected to the first motor 10 and sleeved on the outside of the first driving wheel 11 and the first driven wheel 12; a first movable seat 15, which is eccentrically connected to the first driven wheel 12; and a punching assembly 16, which is connected to the lower end of the first movable seat 15, and the punch 3 is movably connected to the punching assembly 16.

[0022] After the rotating feeder 2 pushes the trim strip to be punched onto the punching mechanism 1, the first motor 10 drives the first drive wheel 11 to rotate. When the first drive wheel 11 rotates, it drives the first driven wheel 12 to rotate via the belt 13. Since the first moving seat 15 is eccentrically connected to the first driven wheel 12, the rotation of the first driven wheel 12 can drive the first moving seat 15 to perform a cyclic reciprocating motion in the vertical direction, thereby driving the punching assembly 16 to perform a cyclic reciprocating motion in the vertical direction. Since the punch 3 is movably connected to the punching assembly 16, the cyclic reciprocating motion of the punch 3 relative to the trim strip driven by the punching assembly 16 can ensure the continuous punching of the trim strip. The dust cover 14 is set to prevent dust in the workshop and waste generated during trim strip punching from entering the punching mechanism 1 and affecting the normal operation of the punching mechanism 1.

[0023] Furthermore, the first fixed base 9 includes: a main body block 17, a first support frame 8 including two parallel first columns 18, the main body block 17 being movably connected to the first columns 18, the upper ends of the two first columns 18 being connected by a first connecting block 19, a first lead screw 20 being rotatably mounted on the first connecting block 19, one end of the first lead screw 20 being connected to the main body block 17; a rotating frame 21, the main body block 17 having three rotating platforms 22 staggered along the vertical direction, wherein the upper rotating platform 22 is hinged with a bolt 23, the rotating frame 21 having a through groove penetrating the upper end face of the rotating frame 21, the bolt 23 being inserted into the through groove and fixed by a nut, the lower part of the rotating frame 21 being hinged to the other two lower rotating platforms 22, and the first motor 10 being fixed to the rotating frame 21.

[0024] The first column 18 is used to fix the main body block 17 and the first support frame 8. During the commissioning and trial production, in order to ensure that each movement of the punch 3 can punch the trim strip, the relative position between the punch 3 and the trim strip can be adjusted by rotating the first lead screw 20 to move the main body block 17 on the first column 18.

[0025] Since the first motor 10 is fixed on the rotating frame 21 and the first driven wheel 12 is rotatably connected to the first fixed seat 9, when adjusting the first fixed seat 9 on the first support frame 8, if the first motor 10 is fixedly installed on the first fixed seat 9, it will affect the connection between the first motor 10 and the first driven wheel 12, making it impossible for the first motor 10 to drive the first driven wheel 12 to rotate normally. Therefore, this solution uses the rotating table 22 and bolts 23 to hinge the rotating frame 21 to the main body block 17. In this way, when adjusting the position of the first fixed seat 9 on the first support frame 8, the position of the first motor 10 on the rotating frame 21 can be adjusted by loosening and tightening the bolts 23 to adapt to the adjustment of the distance and angle between the first motor 10 and the first driven wheel 12, thereby ultimately ensuring the normal operation of the punching mechanism 1.

[0026] Furthermore, the first movable seat 15 includes: a connecting rod 24; two rotating shafts 25 are coaxially arranged on the main body block 17, one end of which is connected to the first driven wheel 12; the two rotating shafts 25 are connected on opposite sides by the connecting rod 24; the axis of the connecting rod 24 is not collinear with the axis of the rotating shaft 25; a second connecting block 26, which is sleeved on the outer wall of the connecting rod 24; a connecting pin 27, one end of which is connected to the second connecting block 26, and the other end of which is provided with a ball head 28; a movable block 29, which is slidably arranged on the main body block 17; the ball head 28 is movably inserted into the upper end of the movable block 29; and a punching assembly 16 is connected to the lower end of the movable block 29.

[0027] The connecting rod 24 is used to realize the eccentric connection between the first moving seat 15 and the first driven wheel 12. The connecting rod 24 and the two rotating shafts 25 can be integrally formed, or the two rotating shafts 25 can be machined first and then connected to the connecting rod 24 by threaded connection or interference fit. The second connecting block 26 and the connecting pin 27 are used to realize the connection between the connecting rod 24 and the moving block 29. Since the connecting rod 24 is eccentrically connected to the opposite side of the two rotating shafts 25, when the rotating shafts 25 rotate under the drive of the second driven wheel 46, they will drive the connecting rod 24 to move in the vertical and horizontal directions. By setting the ball head 28 on the connecting pin 27 and movably inserting the ball head 28 into the moving block 29, when the connecting rod 24 moves, only the vertical movement of the connecting rod 24 is transmitted to the moving block 29, while ignoring the influence of the horizontal movement of the connecting rod 24 on the moving block 29, thereby ensuring that the punch 3 connected to the lower end of the moving block 29 will only move in the vertical direction.

[0028] Furthermore, the punching assembly 16 includes: a second fixing seat 30 connected to the first support frame 8, wherein a contour block 31 is provided on the second fixing seat 30 for insertion into the trim strip to be punched; a third fixing seat 32 connected to the moving block 29; a punch fixing block 33 connected to the lower end of the third fixing seat 32, wherein the punch 3 mounting base is connected to the punch fixing block 33 and the upper end of the punch 3 abuts against the lower end face of the third fixing seat 32; a fourth fixing seat 34 connected below the punch fixing block 33; and an elastic member 35, one end of which passes through the punch fixing block 33 and abuts against the third fixing seat 32. On the fixed seat 32, the other end of the elastic member 35 abuts against the fourth fixed seat 34; the guide post 36, one end of which is fixed on the second fixed seat 30, and the other end of which passes through the fourth fixed seat 34 and punch fixing block 33 and is movably inserted into the third fixed seat 32; the first guide member 37 is connected to the side of the second fixed seat 30, and the first guide member 37 is provided with a guide groove 38 that is parallel to the vertical direction of the contour block 31; the guide ramp 39, the contour block 31 is provided with a material leakage hole located below the punch 3, and the guide ramp 39 is connected to the first support frame 8 and located below the material leakage hole.

[0029] After the trim strip passes through one of the rotating feeders 2, it is fitted onto the outer wall of the contour block 31 to prevent the trim strip from being affected by the lack of internal support during punching, which would affect the punching accuracy. Then, the third fixed seat 32, driven by the moving block 29, performs a cyclic reciprocating motion in the vertical direction. Since the punch 3 is fixed between the third fixed seat 32 and the punch fixing block 33, the movement of the third fixed seat 32 drives the punch fixing block 33 and the punch 3 to move, completing the punching operation of the trim strip. When the third fixed seat 32 and the punch fixing block 33 move, under the push of the second fixed seat 30, the distance between the punch fixing block 33 and the fourth fixed seat 34 decreases, thereby compressing the elastic member 35. After the third fixed seat 32 and the punch fixing block 33 move upward and reset, the elastic member 35 returns to its extended state. The first fixed seat 9 moves the fourth fixed seat 34 away from the punch fixing block 33. When the first fixed seat 9 moves, it can push the waste material adhering to the punch 3 away from the punch 3 to prevent the waste material adhering to the punch 3 from affecting the next punching operation of the punch 3. The waste material punched off from the trim falls into the guide chute 39 through the discharge hole and finally leaves the punching assembly 16 under the action of its own gravity. The guide groove 38 provided on the first guide member 37 is used for the trim to pass through and to ensure that the trim can be fitted horizontally on the outer wall of the contour block 31, preventing the trim from being tilted on the contour block 31 and affecting the punching accuracy of the trim. The guide post 36 is used to ensure the movement direction of the punch 3 by ensuring the movement direction of the fourth fixed seat 34 and the punch fixing block 33, thereby ultimately ensuring the punching accuracy of the trim. Preferably, the elastic member 35 can be a spring or a rubber product.

[0030] Furthermore, both rotating feeding components 2 include: a fifth fixed seat 40, which is disposed on the side of the first support frame 8; two second columns 41, which are symmetrically connected to the fifth fixed seat 40, the upper ends of the two second columns 41 are connected by a third connecting block 42, and the lower parts of the two second columns 41 are connected to a sixth fixed seat 43; a second lead screw 44, which is inserted into the third connecting block 42; a seventh fixed seat 45, which is connected to the upper part of the second column 41 and the lower end of the second lead screw 44, and a second driven wheel 46 is rotatably disposed on the seventh fixed seat 45; a second motor 47, which is connected to the side of the fifth fixed seat 40, the output end of the second motor 47 is connected to a second driving wheel 48, the second driving wheel 48 is rotatably connected to the sixth fixed seat 43 and is located below the second driven wheel 46; and a second guide member 49, which is disposed on the side of the fifth fixed seat 40, and a first guide through hole 50 is provided on the second guide member 49.

[0031] During operation, the decorative strip is placed between the second driving wheel 48 and the second driven wheel 46 after passing through the first guide hole 50. The height of the seventh fixing seat 45 on the second column 41 is adjusted by the first lead screw 20, and the distance between the second driven wheel 46 and the second driving wheel 48 is adjusted so that the second driving wheel 48 can drive the decorative strip to move when it rotates.

[0032] Each rotating feeding mechanism may be equipped with a second motor 47, or a second motor 47 may be installed on two rotating feeding mechanisms to drive the two second drive wheels 48 to rotate. When there is only one second motor 47, the output end of the second motor 47 can be connected in series with the two second drive wheels 48 through a pulley set, so that one motor can drive the two second drive wheels 48 to rotate.

[0033] The second column 41 is used to fix the seventh fixing seat 45 in space, and the third connecting block 42 is used to fix the second lead screw 44. Preferably, a rotating member is provided above the second lead screw 44, and rotating the rotating member can drive the second lead screw 44 to rotate on the third connecting block 42.

[0034] Furthermore, the cutting mechanism 4 includes: a machine base 51, on which a linear guide rail 52 is provided, and a clamping member 5 is movably mounted on the linear guide rail 52; a second support frame 53, which is connected to the machine base 51 and located to the side of the linear guide rail 52, and a first cylinder 54 and a second cylinder 55 are arranged adjacent to each other on the second support frame 53, the output directions of the first cylinder 54 and the second cylinder 55 are both arranged in the vertical direction, and the cutter 6 is connected to the output end of the second cylinder 55; and a support platform 56, which is connected to the machine base 51 and located to the side of the second support frame 53. A fixed support block 57 is fixed on the support platform 56. The output end of the first cylinder 54 is connected to a pressing block 58. The first cylinder 54 is used to drive the pressing block 58 to move and be positioned above the fixed support block 57. A third cylinder 59 is vertically positioned on the machine base 51 and below the support platform 56. A movable support block 60 is inserted on the support platform 56. The movable support block 60 is connected to the output end of the third cylinder 59 and is positioned below the cutter 6. A first sensor 61 is connected to the support platform 56 and electrically connected to the linear guide rail 52.

[0035] Linear guide rail 52 is used to move clamping member 5 on machine base 51, thereby enabling clamping member 5 to pull the trim strip. After clamping member 5 pulls the trim strip to the preset position, first cylinder 54 first drives pressing block 58 to move closer to fixed support block 57, pressing the trim strip between pressing block 58 and fixed support block 57. Then, third cylinder 59 drives movable support block 60 to support the bottom end of the trim strip. Finally, second cylinder 55 drives cutter 6 to move towards movable support block 60, thereby cutting the trim strip with cutter 6 at the output end of second cylinder 55. After the trim strip is cut, the linear guide rail 52 moves back to its initial position and clamps the end of the trim strip again, and performs the next pulling operation, thereby automatically and continuously completing the trim strip cutting action. The first sensor 61 is used to sense the position of the clamping member 5. After the clamping member 5 is reset, it transmits the sensing information to the linear guide rail 52 and controls the linear guide rail to stop, so that the clamping member 5 remains stationary on the linear guide rail 52, thereby ensuring that the clamping member 5 clamps the trim strip in the same position every time, and ultimately ensuring that the length of the trim strip after cutting is consistent.

[0036] Furthermore, the clamping member 5 includes: a second movable seat 62 connected to the linear guide rail 52; a fourth cylinder 63 connected to the second movable seat 62; and two symmetrically arranged grippers 64 connected to the output end of the fourth cylinder 63, wherein the fourth cylinder 63 is used to drive the two grippers 64 to move closer or further apart on the fourth cylinder 63.

[0037] After the clamping member 5 remains stationary on the linear guide rail 52, the fourth cylinder 63 drives the two grippers 64 to approach each other and clamp the upper and lower ends of the trim strip, completing the clamping action of the clamping member 5 on the trim strip. The second moving seat 62 is used to connect the linear guide rail 52 and the fourth cylinder 63.

[0038] Furthermore, the second support frame 53 includes: an eighth fixed base 65, which is mounted on the machine base 51; at least two third columns 66, which are symmetrically connected to the eighth fixed base 65, the upper ends of the third columns 66 are connected by a fourth connecting block 67, and the lower part of the third columns 66 is connected to a ninth fixed base 68; a third lead screw 69, which is inserted into the fourth connecting block 67; a tenth fixed base 70, which is connected to the upper part of the third column 66 and to the lower end of the second lead screw 44, and a third driven wheel 71 is rotatably mounted on the tenth fixed base 70; a fourth driven wheel 72, which is rotatably connected to the ninth fixed base 68, and the fourth driven wheel 72 is located below the third driven wheel 71; and a third guide member 73, which is connected to one of the third columns 66, and the third guide member 73 is provided with a second guide through hole 74.

[0039] The third lead screw 69 is used to adjust the position of the tenth fixed seat 70 on the third column 66, thereby adjusting the distance between the third driven wheel 71 and the fourth driven wheel 72. The second guide through hole 74 provided on the third guide member 73 is used for the trim strip to pass through, so that the trim strip always remains horizontal, thereby ensuring the cutting accuracy of the trim strip.

[0040] Furthermore, the material storage mechanism 7 includes: a third support frame 75 having a material passage for the trim strip to pass through; and a second sensor 76 distributed vertically on the third support frame 75, the second sensor 76 being disposed on the side wall of the material passage and electrically connected to the linear guide rail 52. The position of the trim strip between the punching mechanism 1 and the cutting mechanism 4 is sensed by the second sensor 76 at different heights in the vertical direction, thereby controlling the movement speed of the clamping member 5 on the cutting mechanism 4.

[0041] The material passage on the third support frame 75 is used for the trim strip to pass through. During operation, when the second sensor 76 below the third support frame 75 senses the trim strip, it indicates that there is a large amount of trim strip on the storage mechanism 7. At this time, the second sensor 76 transmits the sensing signal to the linear guide rail 52 and increases the driving speed of the linear guide rail 52 on the clamping member 5. When the second sensor 76 above the third support frame 75 senses the trim strip, it indicates that the trim strip is almost horizontal between the punching mechanism 1 and the cutting mechanism. At this time, the amount of trim strip stored on the storage mechanism 7 is small. If the linear guide rail 52 continues to drive the trim strip to move, it will pull the trim strip that has not been punched on the punching mechanism 1 away from the punching mechanism 1. At this time, the storage mechanism 7 can control the output speed of the linear guide rail 52 through the second sensor 76 to slow down the pulling of the clamping member 5 on the trim strip, thereby coordinating the working speed between the punching mechanism 1 and the cutting mechanism 4, and finally ensuring the production accuracy of the trim strip.
