[0034] The terminal wire can arbitrarily select the number of wires and the spacing, making the connection more convenient, reducing the volume of electronic products, reducing production costs, and improving production efficiency. It is suitable for use as a data transmission cable between mobile components and the main board, between PCB boards, and in miniaturized electrical equipment. There are a variety of common specifications, and it is currently widely used for the connection between the print heads of various printers and the main board, as well as for signal transmission and board-to-board connection in products such as plotters, scanners, copiers, audio systems, liquid crystal appliances, fax machines, and various DVD players.

[0035] An automated production shearing device for terminal wires in the related art, with publication number CN218192290U, comprises a workbench, a portable component is provided at the front end of the workbench, a clamping component is provided at the upper end of the workbench near one side, a material receiving box is provided at the rear end of the workbench, a slide groove is provided at the upper end of the workbench, a return frame is fixedly installed at the upper end of the workbench near the other side, and two cylinders 1 are fixedly installed at the upper end of the return frame. The output shaft of the cylinder 1 passes through the upper end outer surface of the return frame, and a shearing knife is fixedly installed at the lower end of the output shaft of the cylinder 1, a knife seat is fixedly installed inside the return frame near the bottom end, the shearing knife and the knife seat are in the same vertical plane, and the shape of the knife seat is V-shaped, and a controller is fixedly installed at the front end of the return frame.

[0036] However, an automated production shearing device for terminal wires in the related art requires manual placement of the terminal wires on a workbench for shearing, which makes it difficult to ensure that the terminal wires are neatly placed, and easily causes the terminal wires to be of different lengths after shearing.

[0037] Based on this, in order to improve the problems in the related art, the embodiments of the present application provide the following solutions.

[0038] Please also read Figure 1 and Figure 4 The embodiment of the present application provides a shearing device for terminal wire production, including a frame 1, legs 2, a shearing mechanism, a power mechanism and a limiting plate 5. The power mechanism is used to provide power to the terminal wire to send it to the limiting plate 5. The limiting plate 5 is used to adjust the movement direction of the terminal wire. The shearing mechanism is used to shear the terminal wire.

[0039] Please also read Figures 1 to 6 The legs 2 are arranged at the bottom of the frame 1, the shearing mechanism, the power mechanism and the limit plate 5 are all arranged on the frame 1, and a plurality of limit grooves 51 are provided on the limit plate 5. The power mechanism includes a motor 41, a first pressure roller 42 and a second pressure roller 43. The outer circumferential surfaces of the first pressure roller 42 and the second pressure roller 43 are each provided with a plurality of pressing grooves 422, and the number of the pressing grooves 422 is equal to the number of the limit grooves 51. The motor 41 is arranged at the bottom of the frame 1, and the first pressure roller 42 and the second pressure roller 43 are both rotatably connected to the frame 1. The end of the first pressure roller 42 close to the motor 41 is sleeved with a first gear 421, and the end of the second pressure roller 43 close to the first motor 41 is sleeved with a second gear 431. The first gear 421 is meshed with the second gear 431 for transmission, and the output end of the motor 41 is transmission-connected to the end of the second pressure roller 43 close to the motor 41 through a transmission wheel and a transmission belt.

[0040] As can be seen from the above, when the shearing device for producing terminal wires provided by the embodiment of the present application works, the output end of the motor 41 rotates to drive the second pressure roller 43 to rotate through the transmission wheel and the transmission belt. The second pressure roller 43 drives the first pressure roller 42 to rotate through the first gear 421 and the second gear 431. When multiple terminal wires are sent to the power mechanism, the staff can feed each terminal wire between the respective pressure slots 422. The first pressure roller 42 and the second pressure roller 43 tightly press the terminal wire between them through the pressure slots 422 and rotate to push the terminal wire towards the limiting plate 5. The staff can then feed multiple terminal wires into the entrances of the respective limiting slots 51 respectively. The terminal wire can adjust its moving direction through the limiting slot 51 and continue to move towards the subsequent shearing mechanism, so as to ensure the neatness of the positions of each terminal wire when being sheared by the shearing mechanism and avoid the phenomenon that the terminal wires are of different lengths after being sheared.

[0041] In some embodiments, please refer to Figures 1 to 8 simultaneously. The shearing mechanism includes a support plate 31, a cylinder 32, a tool holder 33, a blade 34, and a fixing bolt 38. The support plate 31 is arranged on the top of the frame body 1. A chute 11 and a shearing slot 12 are formed on the frame body 1. Sliders 331 are arranged at both ends of the tool holder 33. The sliders 331 are slidably connected inside the chute 11. The tool holder 33 is slidably connected to the frame body 1 through the sliders 331 and the chute 11. The cylinder 32 is arranged on the top of the support plate 31. The output end of the cylinder 32 passes through the support plate 31 and is fixedly connected to the top of the tool holder 33. An installation slot 333 is formed on the tool holder 33. A plurality of threaded holes 334 are formed on both the tool holder 33 and the blade 34. The blade 34 is connected inside the installation slot 333 through the fixing bolt 38. The cross-section of the blade 34 is an isosceles trapezoid. One side of the blade 34 is flush with one side of the shearing slot 12 close to the limiting plate 5. A plurality of spring slots 332 are also formed on the tool holder 33. A connecting column 35 is slidably connected inside the spring slot 332. A spring 36 is also arranged inside the spring slot 332. One end of the spring 36 abuts against the top of the spring slot 332, and the other end of the spring 36 abuts against the top of the connecting column 35. A pressing plate 37 is arranged at the end of the connecting column 35 away from the spring 36. One side of the pressing plate 37 is fixedly connected to the end of the connecting column 35 away from the spring 36. An anti-slip pad 371 is arranged at the bottom of the pressing plate 37. One side of the anti-slip pad 371 is fixedly connected to the bottom of the pressing plate 37. A clamping strip 13 and a storage basket 14 are also arranged on the frame body 1. The storage basket 14 is clamped to the frame body 1 through the clamping strip 13. A support strip 141 is arranged on one side of the storage basket 14. The side of the support strip 141 away from the storage basket 14 abuts against the support leg 2.

[0042] With such a setting, when multiple terminal wires are sent to the shearing mechanism by the power mechanism and the heads of the terminal wires move a certain distance, the motor 41 stops rotating, the terminal wires stop moving, and the output end of the air cylinder 32 drives the tool holder 33 to move downward. When the blade 34 and the anti-slip pad 371 simultaneously contact the terminal wires, the tool holder 33 continues to move downward, and the spring 36 is compressed under the pressure between the spring groove 332 and the connecting column 35. The connecting column 35 slides upward relative to the spring groove 332, and the connecting column 35 transmits the reaction force of the spring 36 to the pressing plate 37, so that the anti-slip pad 371 presses the parts of the terminal wires on both sides of the shearing groove 12 tightly against the frame body 1. At this time, the tool holder 33 continues to move downward, and the blade 34 and one side of the shearing groove 12 form a shearing force on the terminal wires to cut the terminal wires. The anti-slip pad 371 can increase the friction between the pressing plate 37 and the terminal wires, preventing the terminal wires from sliding when the blade 34 shears the terminal wires and thus being unable to be effectively sheared. After the terminal wires are sheared, the output end of the air cylinder 32 drives the tool holder 33 to move upward, and the anti-slip pad 371 leaves the terminal wires. The terminal wires fall into the interior of the storage basket 14 under the action of gravity to facilitate collection by the staff. At this time, the motor 41 rotates to continue driving the terminal wires to move forward to prepare for the next shearing operation; after the device is used for a long time, the sharpness of the blade 34 will continuously decrease due to wear, and the shearing effect of the blade 34 on the terminal wires will also continuously decrease. At this time, the staff can unscrew the fixing bolt 38, take out the blade 34 from the installation groove 333 and replace it with a new blade 34, ensuring the long-term stable operation of the device; when the device is working, the terminal wires stored in the interior of the storage basket 14 will continuously increase, and the part where the storage basket 14 is clamped with the clamping strip 13 will bear a large torsional force. The support strip 141 can convert this part of the torsional force into the pressure of the support strip 141 on the support leg 2 and the pressure of the storage basket 14 on the clamping strip 13 in the vertical direction, avoiding the part where the storage basket 14 contacts the clamping strip 13 from being overstressed and causing fracture; when the number of terminal wires in the interior of the storage basket 14 reaches a certain amount, the staff can pause the operation of the device, remove the storage basket 14, transport the terminal wires to the next processing location, and replace it with an empty storage basket 14 to continue the operation of the device.

[0043] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
