[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant effects:

[0016] 1. The shearing device for processing flexible flat cables can automatically center the flexible flat cables by aligning the components, and automatically press and position the flexible flat cables when cutting them, thereby preventing the flexible flat cables from shifting during cutting and ensuring the neatness of the cutting of the flexible flat cables, thereby ensuring the cutting quality and efficiency of the flexible flat cables.

[0017] 2. The shearing device for processing flexible flat cables is configured by tilting a U-shaped workbench on a base and providing a baffle at the lower end of a support plate, so that when a worker places the flexible flat cable to be cut on the support plate, the flexible flat cable automatically slides down and one end thereof abuts against the baffle. Subsequently, the flexible flat cable is centered on the support plate under the action of an alignment component. The distance from the baffle to the cutter is the length of the flexible flat cable, thereby avoiding the need to measure the length of the flexible flat cable through a scale line before each cutting, thereby improving the processing efficiency of the flexible flat cable.

[0018] 3. The shearing device for processing flexible flat cables makes the pressure block elastically arranged in the receiving groove of the support plate to avoid the pressure block exerting force on the force block when moving up, so that the limit component releases the restriction on the alignment component, resulting in the alignment plate not being locked. When the flexible flat cable is subsequently aligned again, the alignment plates on both sides of the U-shaped workbench need to be manually pushed away, and then the flexible flat cable is placed between the two alignment plates that are far away from each other, which affects the centering efficiency of the flexible flat cable and improves the working steps of the staff, thereby ensuring the efficiency of the shearing processing of the flexible flat cable.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Example: Refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The present invention provides a shearing device for processing a flexible flat cable, comprising a base 1, a U-shaped workbench 2 is arranged on the top of the base 1, an alignment component for clamping the flexible flat cable and a limit component for limiting the movement of the alignment component are arranged on the U-shaped workbench 2, a first elastic telescopic rod 201 is arranged on the U-shaped workbench 2, a support plate 3 that is movably opposed to the limit component is arranged on the top of the first elastic telescopic rod 201, a support seat 4 is arranged on the top of the U-shaped workbench 2, and a cutting component is arranged on the support seat 4.

[0030] Specifically, the flexible flat cable to be cut is placed on the support plate 3 and the support plate 3 is pressed downward, so that the support plate 3 exerts a force on the first elastic telescopic rod 201, and the support plate 3 is close to the U-shaped workbench 2. The downwardly moved support plate 3 exerts a force on the limiting component, so that the limiting component releases the restriction on the alignment component. The alignment component automatically aligns the flexible flat cable on the support plate 3, so that the flexible flat cable is placed flush on the support plate 3. Then the cutting component is controlled to work. When the cutting component is working, the flexible flat cable is automatically pressed and positioned to prevent the flexible flat cable from being displaced during cutting, thereby ensuring the uniformity of the cutting of the flexible flat cable, thereby ensuring the cutting quality and efficiency of the flexible flat cable.

[0031] Reference Figure 1 , Figure 3 and Figure 5 The alignment component includes a second elastic telescopic rod 5 fixedly mounted on both sides of the U-shaped workbench 2, and an alignment plate 501 is fixedly mounted on one side of the second elastic telescopic rod 5 away from the inner wall of the U-shaped workbench 2, and the support plate 3 is placed between the alignment plates 501 on both sides; specifically, after the limit assembly releases the restriction on the alignment component, the second elastic telescopic rods 5 on both sides of the U-shaped workbench 2 respectively push the alignment plates 501 connected thereto to move, so that the alignment plates 501 on both sides move toward each other and exert side force on the flexible flat cable, so that the flexible flat cable placed on the support plate 3 is centered and aligned.

[0032] Reference Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7The limiting assembly includes a third elastic telescopic rod 6 connected to the U-shaped workbench 2, a force block 601 is arranged at one end of the third elastic telescopic rod 6 away from the U-shaped workbench 2, a first inclined surface is provided at the end of the force block 601, a pressing block 7 movably abutting against the first inclined surface is provided on the support plate 3, a fourth elastic telescopic rod 602 is fixedly provided on the U-shaped workbench 2, a limiting block 603 slidably arranged with the force block 601 is provided on the top of the fourth elastic telescopic rod 602, a positioning groove 5011 cooperating with the limiting block 603 is provided on the alignment plate 501, and a second inclined surface movably abutting against the alignment plate 501 is provided on the top of the limiting block 603.

[0033] Furthermore, the force block 601 is provided with a first slide groove 6011 for the limit block 603 to slide, the limit block 603 is provided with a second slide groove 6031 for the force block 601 to slide, and the inner wall of the second slide groove 6031 is fixed with a wedge block 6032 that movably resists the force block 601.

[0034] Specifically, the flexible flat cable to be cut is placed on the support plate 3 and the support plate 3 is pressed downward, so that the support plate 3 exerts a force on the first elastic telescopic rod 201, and the support plate 3 is close to the U-shaped workbench 2. The downwardly moved support plate 3 drives the pressing block 7 to exert a force on the extrusion slope of the force block 601, so that the force block 601 moves to the side away from the support plate 3 and exerts a force on the third elastic telescopic rod 6. The third elastic telescopic rod 6 contracts under the force, and after the force block 601 moves, it no longer exerts a force on the wedge block 6032 of the limit block 603, so that the limit block 603 moves downward relative to the force block 601 under the pull of the fourth elastic telescopic rod 602, so that the limit block 603 leaves the positioning groove 5011 on the lower side of the alignment plate 501, so that the alignment plate 501 is no longer restricted, and the flexible flat cable on the support plate 3 is pushed by the second elastic telescopic rod 5.

[0035] Reference Figure 5 and Figure 8 The support plate 3 is provided with a receiving groove 301 for accommodating the pressure block 7, and the pressure block 7 is rotatably arranged in the receiving groove 301 by a pin shaft, and a torsion spring 302 is sleeved on the pin shaft, and two ends of the torsion spring 302 are respectively connected to the inner wall of the receiving groove 301 and the pressure block 7; specifically, by making the pressure block 7 and the support plate 3 elastically arranged, when the support plate 3 drives the pressure block 7 to move downward, the pressure block 7 squeezes and pushes the force block 601, and when the support plate 3 drives the pressure block 7 to move upward, the pressure block 7 no longer squeezes the force block 601, and the pressure block 7 is forced to shrink into the receiving groove 301, and when the support plate 3 drives the pressure block 7 to pass over the force block 601, the pressure block 7 is reset and rotated under the action of the torsion spring 302, so as to prepare for the subsequent pressure block 7 to exert force on the force block 601 again.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The cutting assembly includes a hydraulic cylinder 8 fixedly mounted on the support seat 4, a piston rod 801 of the hydraulic cylinder 8 is connected to a mounting plate 802, a cutter 803 is fixedly mounted at the bottom of the mounting plate 802, and the cutting assembly also includes a fifth elastic telescopic rod 804 fixedly connected to the mounting plate 802, an end of the fifth elastic telescopic rod 804 away from the mounting plate 802 is fixedly connected to a lower pressing plate 805, and a groove 8051 for the cutter 803 to slide is provided on the lower pressing plate 805; specifically, when the cutting assembly is working, the activity of the hydraulic cylinder 8 The plug rod 801 drives the mounting plate 802 to move downward, and the mounting plate 802 drives the cutter 803 to move downward, and when the mounting plate 802 moves downward, the fifth elastic telescopic rod 804 drives the lower pressure plate 805 to move, so that the lower pressure plate 805 is first pressed against the central flexible flat cable on the support plate 3. As the hydraulic cylinder 8 continues to operate, the mounting plate 802 drives the cutter 803 to pass through the groove 8051 to shear the flexible flat cable pressed by the lower pressure plate 805, so as to prevent the flexible flat cable from being displaced during shearing and ensure the uniformity of the shearing of the flexible flat cable.

[0037] Reference Figure 1 , Figure 3 and Figure 4 The alignment plate 501 includes a vertical plate 5012 connected to the second elastic telescopic rod 5 and an inclined plate 5013 inclined to the vertical plate 5012. A push rod 8052 is fixed on the lower pressure plate 805 to flexibly abut against the inclined plate 5013. Specifically, when the shearing assembly is working, after the lower pressure plate 805 abuts against the soft flat cable on the support plate 3, the support plate 3 is subjected to a force acting on the first elastic telescopic rod 201, so that the lower pressure plate 805, the soft flat cable, and the support plate 3 are synchronously moved close to the U-shaped workbench 2. The push rod 8052 on the lower pressure plate 805 exerts a force on the inclined plate 5013, so that the inclined plate 5013 drives the vertical plate 5012 to move, so that the alignment plate 501 exerts a force on the second elastic telescopic rod 5. When the alignment plate 501 moves back, it exerts a force on the second inclined surface of the limit block 603, so that the limit block 603 is forced to move downward. When the positioning groove 5011 on the lower side of the alignment plate 501 is aligned with the limit block 603, the limit block 603 elastically resets and is inserted into the positioning groove 5011 to re-limit the positioning of the alignment plate 501.

[0038] Reference Figure 1 and Figure 3The U-shaped workbench 2 is tilted on the base 1, a support 202 is arranged between the base 1 and the U-shaped workbench 2, the support plate 3 is arranged parallel to the U-shaped workbench 2, and a baffle 9 is vertically arranged on the support plate 3; specifically, the U-shaped workbench 2 is tilted on the base 1, and the baffle 9 is arranged at the lower end of the support plate 3, so that when the staff places the soft flat cable to be cut on the support plate 3, the soft flat cable automatically slides down and one end thereof abuts against the baffle 9, and then the soft flat cable is centered on the support plate 3 under the action of the alignment component, and the distance from the baffle 9 to the cutter 803 is the length of the soft flat cable, which avoids measuring the length of the soft flat cable through the scale line before each cutting, thereby improving the processing efficiency of the soft flat cable.

[0039] Reference Figure 1 and Figure 3 A plurality of screw holes 303 are provided on the support plate 3, and a fastening bolt 10 is threadedly provided on the baffle plate 9, and the fastening bolt 10 is movably connected in the screw hole 303; specifically, by matching the fastening bolt 10 on the baffle plate 9 with different screw holes 303 on the support plate 3, the distance between the baffle plate 9 and the cutter 803 is adjusted, so as to control the length of the flexible cable cut each time, which is highly practical.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A cutting groove 304 cooperating with the cutter 803 is provided on the support plate 3, and the cutting groove 304 is placed at the end of the support plate 3 away from the baffle 9. A waste box 11 is fixedly provided on the base 1, and the waste box 11 is placed at the lower side of the end of the support plate 3 away from the baffle 9; specifically, the cutting groove 304 is provided on the support plate 3, so that the cutter 803 is placed in the cutting groove 304 when moving downward, thereby ensuring the cutting effect of the flexible flat cable, and the excess flexible flat cable waste after cutting automatically falls into the waste box 11, thereby realizing automatic collection of waste.

[0041] Working principle: The U-shaped workbench 2 is tilted on the base 1, and a baffle 9 is provided at the lower end of the support plate 3, so that when the worker places the flexible flat cable to be cut on the support plate 3, the flexible flat cable automatically slides down and one end thereof abuts against the baffle 9;

[0042] Then the staff member presses down the support plate 3, so that the support plate 3 exerts a force on the first elastic telescopic rod 201, and the support plate 3 is close to the U-shaped workbench 2. The downwardly moved support plate 3 drives the pressing block 7 to exert an extruding inclined surface force on the force-bearing block 601, so that the force-bearing block 601 moves to the side away from the support plate 3 and exerts a force on the third elastic telescopic rod 6. The third elastic telescopic rod 6 is contracted by the force, and after the force-bearing block 601 moves, it no longer exerts a force on the wedge block 6032 of the limit block 603, so that the limit block 603 moves downward relative to the force-bearing block 601 under the pull of the fourth elastic telescopic rod 602, so that the limit block 603 leaves the positioning groove 5011 on the lower side of the alignment plate 501, so that the alignment plate 501 is no longer restricted, and the soft flat cable on the support plate 3 is pushed under the push of the second elastic telescopic rod 5. It should be noted that the downward pressure on the support plate 3 can be cancelled after the support plate 3 is manually pressed downward to release the movement restriction of the alignment plate 501;

[0043] Then the cutting assembly is controlled, the piston rod 801 of the hydraulic cylinder 8 drives the mounting plate 802 to move downward, the mounting plate 802 drives the cutter 803 to move downward, and when the mounting plate 802 moves downward, the fifth elastic telescopic rod 804 drives the lower pressing plate 805 to move, so that the lower pressing plate 805 is first pressed against the central soft flat cable on the support plate 3, and as the hydraulic cylinder 8 continues to operate, the support plate 3 is subjected to a force acting on the first elastic telescopic rod 201, so that the lower pressing plate 805, the soft flat cable, and the support plate 3 are synchronously moved close to the U-shaped workbench 2, and in this process During the process, the push rod 8052 on the lower pressing plate 805 exerts force on the inclined plate 5013, so that the inclined plate 5013 drives the vertical plate 5012 to move, so that the alignment plate 501 exerts force on the second elastic telescopic rod 5, and when the alignment plate 501 moves back, it exerts force on the second inclined surface of the limit block 603, so that the limit block 603 is forced to move downward, and when the positioning groove 5011 on the lower side of the alignment plate 501 is aligned with the limit block 603, the limit block 603 elastically resets and inserts into the positioning groove 5011 to re-limit the positioning of the alignment plate 501;

[0044] The hydraulic cylinder 8 drives the cutter 803 through the mounting plate 802 to pass through the groove 8051 to cut the flexible flat cable pressed by the lower pressing plate 805, thereby preventing the flexible flat cable from shifting during cutting and ensuring the uniformity of the cutting of the flexible flat cable. The excess soft flat cable waste after cutting automatically falls into the waste box 11, thereby realizing automatic collection of the waste.

[0045] After the shearing of the flexible flat cable is completed, the hydraulic cylinder 8 drives the cutting assembly to move upward through the piston rod 801, and the support plate 3 is no longer subjected to the pressure of the lower pressure plate 805. The support plate 3 is reset and moved upward under the elastic force of the first elastic telescopic rod 201. The pressing block 7 on the outside of the support plate 3 is pressed by the force block 601 during the upward movement and will shrink into the accommodating groove 301 (to prevent the pressing block 7 from continuing to exert force on the force block 601, so that the limit assembly releases the restriction on the alignment assembly, resulting in the alignment plate 501 not being locked, so that when the flexible flat cable is aligned again in the subsequent time, the alignment plates 501 on both sides of the U-shaped workbench 2 need to be manually pushed away, so that the flexible flat cable is placed between the two alignment plates 501 far away from each other, affecting the centering efficiency of the flexible flat cable and improving the work steps of the staff). When the support plate 3 drives the pressing block 7 to cross the force block 601, the pressing block 7 is reset and rotated under the action of the torsion spring 302, preparing for the subsequent pressing block 7 to exert force on the force block 601 again.
