Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of guiding mechanisms for key threading machines that allow for rapid key threading, specifically to a guiding mechanism for a key threading machine that allows for rapid key threading. Background Technology
[0002] In many fields such as machinery manufacturing and electronic equipment production, keying is a crucial step in component assembly, and its quality and efficiency directly affect the overall performance of the product and the production schedule. Keying machines, as key equipment for performing keying operations, play an indispensable role. However, existing keying machines have significant shortcomings in practical use, especially in the progressive application of the binding tape.
[0003] Currently, many keying machines suffer from low efficiency in tape delivery. During keying, the tape needs to be delivered accurately and quickly to the designated position to ensure the key passes smoothly through the component. However, the existing tape delivery mechanism is poorly designed, resulting in slow tape delivery. For example, on some small electronic device production lines, keying machines take a long time to deliver the tape each time, which not only delays the assembly time of individual products but also disrupts the rhythm of the entire production line.
[0004] Furthermore, due to the low efficiency of the strapping advance, the key-threading machine experiences long waiting intervals during operation. In the production process, the various operational steps of the key-threading machine require close coordination; if the strapping advance is not timely, subsequent key-threading actions must wait, reducing the effective working time of the equipment. Frequent waiting intervals not only reduce production efficiency but also increase production costs, as idle equipment means wasted resources. In addition, prolonged waiting times can also lead to operator distraction, affecting work quality.
[0005] With the rapid development of the manufacturing industry, the requirements for production efficiency and product quality are becoming increasingly stringent. Improving the strapping progress efficiency of keying machines and shortening the waiting interval has become an urgent problem to be solved. Developing a keying machine guide mechanism that can effectively address the shortcomings of low strapping progress efficiency and long waiting intervals is imperative, as it is of great significance for enhancing the production competitiveness of enterprises, reducing production costs, and meeting market demands for products.

[0037] like Figures 1-4 As shown, a guide mechanism for a rapid key threading machine according to an embodiment of the present disclosure is illustrated, comprising:
[0038] Guide frame 1 and outer frame 2, wherein the outer frame 2 is fixed to the guide frame 1;
[0039] Entering the push component 3, which is located at the lower end of the guide frame 1;
[0040] A guide and push component 4 is disposed inside the guide frame 1;
[0041] Positioning and docking component 5, wherein the positioning and docking component 5 is disposed at the bottom of the other end of the guide frame 1;
[0042] The push-in component 3 includes an inlet 3-1, which is located at one bottom end of the guide frame 1. The outer surface of the guide frame 1 has a through-hole 3-2, and a fixed roller 3-3 is rotatably connected inside the through-hole 3-2. A telescopic cylinder 3-4 is installed on the outer frame 2, and a fixed plate 3-5 is connected to the output end of the telescopic cylinder 3-4. A first motor 3-6 is installed on the fixed plate 3-5, and a rolling wheel 3-7 is provided at the output end of the first motor 3-6. The rolling wheel 3-7 is movably fitted inside the side surface of the guide frame 1, and the guide frame 1 is located on one side of the bottom of the rolling wheel 3-7.
[0043] In some examples, during the key-threading machine's workflow, an entry and pushing component 3 is designed to smoothly guide the strap into the guide frame 1 in preparation for subsequent key-threading operations. This component includes an inlet 3-1 at one end of the bottom of the guide frame 1, which serves as the initial channel for the strap to enter the guide frame 1. A fixed roller 3-3 is rotatably connected within a passage 3-2 on the outer surface of the guide frame 1, providing initial guidance and support for the strap during the introduction process and reducing friction between the strap and the guide frame 1. A telescopic cylinder 3-4 is mounted on the outer frame 2, and a first motor 3-6 is mounted on a fixed plate 3-5 connected to its output end. A rolling wheel 3-7 at the output end of the first motor 3-6 is movably fitted onto the guide frame 1. Located on the side surface and at the bottom of the roller 3-7, when the telescopic cylinder 3-4 is activated, it can push the fixing plate 3-5 and the roller 3-7 closer to the strap. Then, the first motor 3-6 is activated, driving the roller 3-7 to rotate. Using the friction between the roller 3-7 and the strap, the strap is pulled from the inlet 3-1 into the guide frame 1. When the strap retracts, the roller 3-7 can move outward to clear the tightening path. Through the coordinated work of the inlet 3-1, the through 3-2, the fixing roller 3-3, the telescopic cylinder 3-4, the fixing plate 3-5, the first motor 3-6, and the roller 3-7, the push assembly 3 can effectively guide the strap into the guide frame 1, ensuring the smooth start of the key threading operation.
[0044] like Figures 1-4 As shown, this embodiment proposes that the guide and push assembly 4 includes a pair of inner baffles 4-1, the inner baffles 4-1 are disposed on both sides inside the guide frame 1, the side end face of the inner baffles 4-1 is provided with soft rubber strips 4-2, the soft rubber strips 4-2 are spaced apart, the inner surface of the guide frame 1 is provided with a plurality of protrusions 4-3, and a plurality of anti-detachment wheels 4-4 are rotatably connected inside the guide frame 1, the anti-detachment wheels 4-4 are located between the protrusions 4-3, and the rolling wheels 3-7 are all controlled to rotate by a motor.
[0045] In some examples, during the transfer process after the strap enters the guide frame 1, in order to ensure the stable movement of the strap within the guide frame 1 and prevent deviation or jamming, a guide pushing component 4 is designed. This component includes a pair of inner baffles 4-1 disposed on both sides inside the guide frame 1. Soft rubber strips 4-2 disposed on the side end faces of the inner baffles 4-1 are spaced apart. The soft rubber strips 4-2 can both limit the strap's position and reduce wear on the strap's surface through their flexibility. Several protrusions 4-3 are disposed on the inner surface of the guide frame 1, rotatably connected to the guide frame 1 and located between the protrusions 4-3. Several rotating rollers 3-7 controlled by a motor together constitute the strap pushing and guiding structure. When the motor starts, the rollers 3-7 rotate and use the contact friction with the strap to push the strap forward in the guide frame 1. The protrusion 4-3 further restricts the movement path of the strap, ensuring that the strap moves stably in the predetermined direction. Through the coordinated work of the inner stop strip 4-1, soft rubber strip 4-2, protrusion 4-3, rollers 3-7 and motor, the guiding and pushing assembly 4 can stably keep the strap moving in the guide frame 1, providing stable strap delivery for subsequent keying operations.
[0046] like Figures 1-4 As shown in the figure, the positioning and docking assembly 5 in this embodiment includes a pressure roller 5-1, which is rotatably connected to the lower end of the guide frame 1. A docking groove 5-2 is provided at one bottom end of the guide frame 1, and an arc-shaped groove 5-3 is provided on the upper bottom surface of the guide frame 1. A control motor 5-4 is provided on the outside of the guide frame 1, and a connecting block 5-5 is provided at the output end of the control motor 5-4. A positioning wheel 5-6 is rotatably connected to the side end face of the connecting block 5-5, and the positioning wheel 5-6 is located in the arc-shaped groove.
[0047] In some examples, when the strapping is conveyed to the end of the guide frame 1, a positioning and docking assembly 5 is designed to accurately position one end of the strap so that it can smoothly dock with the keying machine. This assembly includes a pressure roller 5-1 rotatably connected to the lower end of the guide frame 1, which can apply a certain pressure to the strapping to keep it in the appropriate position and state. The docking groove 5-2 opened at one end of the bottom of the guide frame 1 provides an accurate positional reference for the docking of the strapping and the keying machine. The arc-shaped groove 5-3 opened on the upper end face of the bottom of the guide frame 1 is rotatably connected to the side end face of the connecting block 5-5 at the output end of the control motor 5-4 on the outside of the guide frame 1. Furthermore, the positioning wheel 5-6 located in the arc groove cooperates to limit the binding strap, so that the binding strap is located at the docking groove 5-2. The positioning wheel 5-6 in the arc groove 5-3 can further adjust the position and angle of the end of the binding strap to prevent the binding strap from coming off during docking and ensure that one end of the binding strap can be accurately docked with the keying machine. Through the coordinated work of components such as the pressure wheel 5-1, docking groove 5-2, arc groove 5-3, control motor 5-4, connecting block 5-5 and anti-detachment wheel 4-4, the positioning docking assembly 5 can accurately position one end of the binding strap to achieve reliable docking with the keying machine and ensure the smooth progress of the keying operation.
[0048] For example, such as Figure 3 As shown, the lower end of the rolling wheel 3-7 is located between the inner baffles 4-1, and the surface of the rolling wheel 3-7 is in contact with the surface of the soft rubber strip 4-2.
[0049] In some examples, the strap is held between the soft rubber strip 4-2 and the roller 3-7 by the limiting of the roller 3-7, and kept in a centered position to ensure that the strap can pass smoothly through the gap between the soft rubber strip 4-2 when it is pulled out.
[0050] For example, such as Figure 3 As shown, the surface of the protrusion 4-3 is an inclined structural surface.
[0051] In some examples, the structural surfaces are tilted to prevent the straps from getting stuck on the right-angled edges during movement.
[0052] For example, such as Figure 1 As shown, the anti-detachment wheel 4-4 and the connecting block 5-5 can be driven to rotate 90° by the control motor 5-4.
[0053] In some examples, a 90° rotation angle allows the anti-slip mechanism to completely disengage from the arc groove 5-3, avoiding the straps.
[0054] In actual use: Insert the strap into the inlet 3-1 at the bottom of the guide frame 1. Start the telescopic cylinder 3-4 to make the fixing plate 3-5 drive the rolling wheel 3-7 to approach the strap. Then start the first motor 3-6. The rolling wheel 3-7 rotates and pulls the strap into the guide frame 1. When the strap moves inside the guide frame 1, the inner stop strip 4-1 and the soft rubber strip 4-2 limit it. The protrusion 4-3 and the rolling wheel 3-7 push it forward. When it reaches the end of the guide frame 1, the pressure roller 5-1 presses the strap. Control the motor 5-4 to drive the connecting block 5-5 and the positioning wheel 5-6 to adjust the position of the strap so that it docks with the key threading machine. After docking, the telescopic cylinder 3-4 pulls the rolling wheel 3-7 to move outward. At the same time, control the motor 5-4 to start and rotate the positioning wheel 5-6 outward by 90°. Then tighten the strap.
[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
