Description

Technical Field

[0001] The utility model relates to the technical field of connector terminals, in particular to a rolling knife continuous cutting mechanism. Background Art

[0002] In recent years, with the development of smart technology and the Internet of Things (IoT), connectors have been widely used in various industries, from automotive, industrial, medical, consumer electronics, communications, computers, and aerospace. Wherever there is electronics, there is a connector. With the rapid development of these industries, the demand for connectors is also increasing. Among them, terminals, as an essential component of connectors, are also seeing an increasing use.

[0003] Terminals usually appear in the form of reels and strips at the production end. Before inserting the terminals into the connector housing, it is often necessary to separate the terminals and the strips. Cutting is a common operation method for separating the strips and is also widely used.

[0004] The existing cutting methods are mainly divided into single-piece and multi-piece cutting:

[0005] Single piece cutting: Advantages: fast cutting speed, Disadvantages: large tool wear;

[0006] Multi-piece cutting: Advantages: less tool wear, Disadvantages: slow cutting speed. Utility Model Content

[0007] The purpose of the utility model is to provide a rolling cutter continuous cutting mechanism to solve the problems of large cutting tool wear and slow cutting speed in the existing cutting process.

[0008] The technical solution of the utility model to solve the above technical problems is as follows:

[0009] A roller cutter continuous cutting mechanism comprises: a base and a mounting frame arranged on the base, a rotary cutting assembly is provided on the mounting frame, and a pressing mechanism is provided at the side end of the mounting frame for pressing the terminal strip to be cut;

[0010] The rotary cutting assembly comprises a driven wheel arranged on the pressing mechanism and a driving wheel meshed with the driven wheel, and a cutter for cutting the terminal strip is installed on the driven wheel.

[0011] Preferably, the rotary cutting assembly further comprises a lower rotating shaft inserted into the axis of the driving wheel, and the lower rotating shaft is arranged on the base through a support seat.

[0012] Preferably, a rotating handle is provided at one end of the lower rotating shaft, and the rotating handle drives the driving wheel to rotate through the lower rotating shaft.

[0013] Preferably, the driving wheel includes a feeding lower gear sleeved on the lower rotating shaft and support plates arranged on both sides of the feeding lower gear.

[0014] Preferably, the driven wheel includes an upper rotating shaft inserted into the clamping mechanism and an upper feeding gear arranged at the end of the upper rotating shaft, and a tool mounting plate is provided on one side of the upper feeding gear.

[0015] Preferably, flow channels for coarse positioning and guiding of the terminal strip are provided on both sides of the rotary cutting assembly.

[0016] The utility model has the following beneficial effects:

[0017] Efficient Cutting: The engagement of the driving and driven wheels and the rotation of the handle allow the cutter to be driven quickly for cutting. The cutting speed can be adjusted according to the speed of the driving shaft. The faster the rotation, the faster the cutting speed, thus significantly improving cutting efficiency.

[0018] Precise positioning and guidance: The flow channel set in the mechanism can effectively roughly position and guide the terminal strip, ensuring accuracy during the cutting process. This helps to reduce cutting errors and improve cutting quality.

[0019] Easy Operation and Maintenance: The design of the mechanism simplifies manual loading and cutting. The simple lifting and lowering of the clamping mechanism facilitates quick insertion and cutting preparation. Furthermore, the design of the cutter mounted on the upper shaft makes it easy to replace and maintain the cutter.

[0020] Extended tool life: Because multiple tools are mounted on the driven wheel, they can cut the material strip at predetermined locations. As the number of tools increases, each tool is used less frequently, extending tool life. This helps reduce the frequency and cost of tool replacement.

[0021] Wide applicability: This continuous cutting mechanism can be adapted to the cutting needs of terminal strips of different specifications and types. By adjusting the meshing relationship between the driving and driven wheels and the installation position of the cutter, it can flexibly adapt to different cutting requirements.

DETAILED DESCRIPTION

[0026] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Please refer to Figure 1 The present invention provides a continuous cutting mechanism with a roller cutter, specifically for use in automated or semi-automated electronic component manufacturing, and is particularly suitable for precise continuous cutting of terminal strips. This cutting mechanism is designed to improve cutting efficiency, ensure cutting accuracy, and maximize the life of the cutter. The following is a specific embodiment of the cutting mechanism:

[0028] First, the main components of the cutting mechanism include a base 1 and a mounting frame 2. The base 1 serves as the supporting structure for the entire cutting mechanism and is typically made of a durable material such as steel or carbide to ensure stability and precision during the cutting process. The mounting frame 2, mounted on the base 1, supports and secures the main working components of the cutting mechanism, including the rotary cutting assembly 3 and the clamping mechanism 5. The mounting frame 2 can be connected to the base 1 using bolts or other fasteners, facilitating assembly and maintenance.

[0029] Mounting frame 2 houses a rotary cutting assembly 3, the core component of the cutting mechanism. Its design enables it to continuously cut the terminal strip. The rotary cutting assembly 3 primarily comprises a driven pulley 31 and a driving pulley 32, which transmit power and torque via gear meshing. This design allows the cutting mechanism to achieve efficient cutting operations in a relatively small space.

[0030] Reference Figure 3The specific structure of the driven wheel 31 includes an upper rotating shaft 311, an upper feeding gear 312 and a tool mounting plate 313. The upper rotating shaft 311 is the rotating shaft of the driven wheel 31. Through it, the driven wheel 31 can be connected to the clamping mechanism 5, thereby realizing the function of moving with the clamping mechanism 5. The clamping mechanism 5 includes an upper and lower slider and a locking mechanism. The upper feeding gear 312 is a component that engages with the driving wheel 32. Through the gear engagement, the power of the driving wheel 32 can be transmitted to the driven wheel 31. The tool mounting plate 313 is a component for installing the cutting tool. The tool is usually a plurality of rollers, which are installed on the tool mounting plate 313 at predetermined positions and spacings. When the driven wheel 31 rotates, the tool will cut the terminal strip passing through the flow channel 4.

[0031] Reference Figure 2 The specific structure of the driving wheel 32 includes a lower feed gear 321 and a support plate 322. The lower feed gear 321 is a component that meshes with the upper feed gear 312 of the driven wheel 31. Its main function is to transmit power to the driven wheel 31. The support plate 322 is used to support the lower feed gear 321 and ensure its stable rotation. The lower rotating shaft 323 is inserted into the axis of the driving wheel 32, and the lower rotating shaft 323 is fixed to the base 1 via a support seat 324. In this way, the driving wheel 32 can rotate stably relative to the base 1 and the mounting frame 2.

[0032] To rotate the driving wheel 32, a rotating handle 325 is provided at one end of the lower rotating shaft 323. The rotating handle 325 is a manually operated component that the user grasps and rotates to rotate the driving wheel 32. The rotating handle 325 is designed to be easy to operate and able to withstand the torque generated during rotation. By rotating the handle 325, the user can easily control the cutting speed and accuracy of the cutting mechanism.

[0033] To ensure stable transfer of the terminal strip during cutting and to provide rough positioning and guidance prior to cutting, flow channels 4 are provided on both sides of the rotary cutting assembly 3. These channels are typically made of durable, wear-resistant materials to prevent deformation or damage during long-term use. The design of the flow channels 4 facilitates the insertion and transfer of the terminal strip and effectively prevents the strip from shifting or slipping during cutting.

[0034] During actual use, the user first needs to manually insert the terminal strip into the flow channel 4 and use the flow channel 4 to roughly position and guide the strip. Then, the user needs to lift the clamping mechanism 5 so that the driven wheel 31 can approach the terminal strip from above. The lifting and lowering operations of the clamping mechanism 5 can be achieved by manual operation or other drive mechanisms. After lifting the clamping mechanism 5, the user can pass the terminal strip through the gap between the driving wheel 32 and the driven wheel 31, and adjust the position of the strip so that it is aligned with the tool on the tool mounting plate 313.

[0035] Next, the user needs to rotate the rotary handle 325 of the driving wheel 32 so that the gear teeth of the lower feed gear 321 pass through the holes in the terminal strip. This process ensures the correct engagement between the terminal strip and the driving wheel 32 and prepares for the subsequent cutting operation. The user can then lower the clamping mechanism 5 and secure it in place using the locking mechanism. The locking mechanism can be a bolt, clip, or other fastener, and its function is to ensure that the clamping mechanism 5 does not move or loosen during the cutting process.

[0036] Once the clamping mechanism 5 is locked, the user can rotate the rotary handle 325 again to drive the driving wheel 32. The rotation of the driving wheel 32 will drive the driven wheel 31 to rotate, and the tool on the driven wheel 31 will be used to cut the terminal strip. The cutting speed can be controlled by the speed of the hand rotation.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
