DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figures 1 to 5As shown, the utility model provides a terminal spacing cutting device, including a frame 1, and two symmetrical guiding mechanisms are provided on the front of the frame 1, so that the two guiding mechanisms are used to convey the terminal. The terminal can be placed between the two guiding mechanisms. A guide frame 3 is fixedly connected to the front of the frame 1, and an opening is provided on the guide frame 3 for taking out the remaining terminal in the guide frame 3, and the guide frame 3 is located on the right side of the two guiding mechanisms. After the terminal is conveyed through the two guiding mechanisms, it can be sent to the guide frame 3 to ensure the conveying accuracy of the terminal. A shearing mechanism for cutting the terminal is provided at the right end of the guide frame 3. When the terminal extends from the right end of the guide frame 3, it can be cut by using the shearing mechanism.

[0025] The guide mechanism includes a stepper motor 2, a second transmission wheel 17 and two third transmission wheels 16. The stepper motor 2 is installed on the back of the frame 1. The output end of the stepper motor 2 is fixedly connected to the first transmission wheel 21. The second transmission wheel 17 and the two third transmission wheels 16 are movably arranged on the front of the frame 1. The second transmission wheel 17 and the first transmission wheel 21 are on the same axis. A conveyor belt 18 is connected between the first transmission wheel 21, the second transmission wheel 17 and the two third transmission wheels 16. The surface of the conveyor belt 18 is fixedly connected with a silicone pad, which can increase the contact friction with the terminal. Through the arrangement of the above structure Under the present invention, the terminal blocks can be transported between the two conveyor belts 18, and the distance between the two conveyor belts 18 can be adjusted, which is suitable for terminal blocks of different thicknesses. The operation of the stepper motor 2 is used to realize the fixed-distance transportation of the terminal blocks, so that the terminal blocks can be cut in sections or one by one, which improves the flexibility of the device and is convenient for personnel to maintain the device. The machinery, parts and equipment in this device all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0026] like Figure 2 、 Figure 3 and Figure 4 As shown, the guiding mechanism also includes a first slide groove 12 and two second slide grooves 15, and the first slide groove 12 and the two second slide grooves 15 are all opened on the frame 1. The surface of the second transmission wheel 17 is sleeved with a first sleeve 10, and the first sleeve 10 slides horizontally in the first slide groove 12, and the surfaces of the two third transmission wheels 16 are sleeved with second sleeves 14, and the two second sleeves 14 slide longitudinally in the two second slide grooves 15 respectively. Through the setting of the above structure, the second transmission wheel 17 can only slide horizontally in the first slide groove 12 through the first sleeve 10, and the third transmission wheel 16 can only slide vertically in the second slide groove 15 through the second sleeve 14, so that the guiding mechanism has an adjustment function, which is beneficial to the transportation of terminal blocks of different thicknesses.

[0027] like Figure 2 and Figure 4 As shown, the guiding mechanism also includes an electric push rod 8 and a lifting frame 9. The electric push rod 8 is installed on the back of the frame 1, and the lifting frame 9 is set on the back of the frame 1, and the telescopic end of the electric push rod 8 is connected to the lifting frame 9. The rear ends of the two third transmission wheels 16 are rotatably connected to the lifting frame 9. The operation of the electric push rod 8 can control the lifting and lowering of the lifting frame 9, and further control the synchronous lifting and lowering of the two third transmission wheels 16. The rear end of the second transmission wheel 17 is rotatably connected to the fixed plate 13. One end of the lifting frame 9 is hinged with a connecting rod 11, and the other end of the connecting rod 11 is hinged on the fixed plate 13. Through the setting of the above structure, the spacing between the upper and lower conveyor belts 18 is controlled, the transportation stability of the terminal blocks is ensured, and the maintenance of the two conveyor belts 18 is also convenient. When the electric push rod 8 controls the lifting frame 9 to rise, the two third transmission wheels 16 will move upward together. At the same time, the connecting rod 11 will push the fixed plate 13 to move, so that the conveyor belt 18 is away from the center position of the frame 1, otherwise the conveyor belt 18 is close to the center position of the frame 1.

[0028] like Figure 1 and Figure 5 As shown, the shearing mechanism includes a cylinder 4 and a shearing groove 19. The cylinder 4 is installed on the front of the frame 1. The shearing groove 19 is opened on the inner bottom wall of the right end of the guide frame 3. The telescopic end of the guide frame 3 is fixedly connected with a shearing knife 20, and the shearing knife 20 is located directly above the shearing groove 19. A notch is opened above the right end of the guide frame 3, and the shearing knife 20 is located in the notch at the right end of the guide frame 3. Through the setting of the above structure, the shearing knife 20 is used to cut the wiring terminals in the guide frame 3 downward under the operation of the cylinder 4, and the wiring terminals will fall downward after cutting.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, a collecting frame 6 is fixedly connected to the front of the frame 1, and the collecting frame 6 is located at the lower right of the guide frame 3. Through the setting of the collecting frame 6, it is convenient to collect the wiring terminals cut at the right end of the guide frame 3.

[0030] like Figure 1 and Figure 3 As shown, a guide frame 7 is fixedly connected to the front of the frame 1, the left end diameter of the guide frame 7 is larger than the right end diameter, and the right end of the guide frame 7 is close to the two third transmission wheels 16 on the left side. Through the setting of the guide frame 7, the terminal blocks can be guided and transported to prevent the terminal blocks from shifting during transportation.

[0031] like Figure 1 and Figure 2As shown, a protective frame 5 is provided on the front of the frame 1. The protective frame 5 is detachable and can be easily removed from the frame 1 to maintain the components on the front of the frame 1. The protective frame 5 is transparent, so that when the components on the front of the frame 1 are in operation, it is convenient for personnel to observe the working conditions and the conveying status of the terminal blocks.

[0032] The working principle and usage process of the present invention are as follows: the wiring terminals are transported between the two conveyor belts 18 through the guide frame 7, the two conveyor belts 18 are used to squeeze the wiring terminals, and then the two stepper motors 2 are operated synchronously to control the two conveyor belts 18 to transport the wiring terminals at a fixed distance, so that the wiring terminals extend through the right end of the guide frame 3. At this time, the operation of the cylinder 4 causes the shear knife 20 to cut the wiring terminals in an orderly manner. When it is necessary to adjust the spacing between the two conveyor belts 18, it is only necessary to control the operation of the two electric push rods 8 to move the two lifting frames 9 away from each other, so that the two sets of third transmission wheels 16 can be moved away from each other, and at this time the two fixed plates 13 are also pushed to one side by the two connecting rods 11 respectively, so that the stability of the two conveyor belts 18 is still guaranteed when the spacing is adjusted, thereby facilitating the transportation of wiring terminals of different thicknesses.
