[0023] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0024] Reference Figures 1 to 4 The present invention proposes an automatic PIN insertion assembly mechanism for a rubber core, including a mounting frame 1, a feeding mechanism and a processing mechanism. The mounting frame 1 is formed with a working surface 11, and a processing position 12 is provided on the top of the working surface 11; the feeding mechanism includes a rubber core turntable 21, a PIN pin wheel 22 and a first motor 23. The PIN pin wheel 22 is arranged adjacent to the processing position, and a PIN pin tape is wound around the surface of the PIN pin wheel 22. The first motor 23 is driven and connected to the PIN pin wheel 22 to rotate it so that the PIN pin tape is transported to the processing position 12. The rubber core turntable 21 is arranged above the mounting frame 1 and is partially in the processing position 12. The rubber core turntable 21 is connected to an external drive source to Make it rotate; the processing mechanism includes a rotary wheel assembly 3, a second motor 4, a first slide bar 5 and a second slide bar 6. The rotary wheel assembly 3 is arranged on the working surface 11 and has an inner wheel portion 31 and an outer wheel portion 32. The first slide bar 5 and the second slide bar 6 are movably connected to the inner wheel portion 31 and the outer wheel portion 32 respectively, and the tops of the first and second slide bars 6 are both in the processing position 12. A movable knife 51 is provided on the top of the first slide bar 5, and a pressure block 61 is connected to the top of the second slide bar 6. The second motor 4 drives the rotary wheel assembly 3 to rotate and move the first and second slide bars 6. The pressure block 61 presses the PIN foot material strip and the material on the rubber core turntable 21, and the movable knife 51 cuts the PIN foot material strip.

[0025] As you can understand, mounting frame 1 serves as the framework supporting the entire mechanism. The loading mechanism is responsible for providing and delivering PIN pin strips and rubber cores, ensuring a steady supply of materials. The processing mechanism is responsible for specific operations such as PIN pin insertion and cutting. One side of mounting frame 1 features a work surface 11, where the machine operates, processing and assembling materials. Atop work surface 11 is a processing station 12, where operations such as PIN pin insertion take place.

[0026] The loading mechanism transports the PIN pin strips and rubber cores to the processing station 12, ensuring a continuous supply of material. The rubber core is placed on the rubber core turntable 21, which rotates to deliver the cores to the processing station 12 for insertion. The turntable 21 is connected to an external drive source (such as a motor) for rotation. The PIN pin feed wheel 22 is used to deliver the PIN pin strips to the processing station 12. The PIN pin strips are wound around the wheel and driven by a first motor 23 to rotate, transporting the strips to the processing station 12. The first motor 23 drives the PIN pin feed wheel 22 to rotate, controlling the transport of the PIN pin strips.

[0027] The purpose of the processing mechanism is to realize the actual assembly and processing operations. The wheel assembly 3 is a wheel installed on the working surface 11, which includes two parts, an inner and an outer part. By rotating, it can drive the slide bar to operate. The first slide bar 5 and the second slide bar 6 are respectively connected to the inner and outer parts of the wheel, and drive the slide bar to move by rotation. A movable knife 51 is installed on the top of the first slide bar 5 for cutting the PIN foot material strip, and a pressure block 61 is connected to the top of the second slide bar 6 for pressing the rubber core and the PIN foot on the rubber core turntable 21 to ensure the insertion of the PIN foot. The second motor 4 drives the wheel assembly 3 to rotate, driving the movement of the slide bar. During the rotation, the movable knife 51 will cut the PIN foot material strip, and the pressure block 61 will press the rubber core and the PIN foot together to complete the insertion and fixation operation of the PIN foot.

[0028] Reference Figures 3 to 4 In one embodiment of the present application, the wheel assembly 3 includes an outer wheel portion 32 and an inner wheel portion 31. The outer wheel portion 32 includes a wheel ring 321 and an irregular plate 322. The wheel ring 321 is connected to the surface of the irregular plate 322. When the outer wheel portion 32 rotates, the edge of the irregular plate 322 can partially contact and push the second slide rod 6; the inner wheel portion 31 includes a wheel core 311 and a deflection wheel 312. The wheel core 311 is connected to the surface of the irregular plate 322 and is located inside the wheel ring 321. The deflection wheel 312 is embedded in the side of the wheel core 311. The second motor 4 is connected to the wheel core 311, and the first slide rod 5 is connected to the deflection wheel 312.

[0029] As can be understood, the ring 321 is an annular structure connected to the irregular plate 322. The irregular plate 322 has an irregular elliptical edge shape, which affects the motion trajectory of the outer ring 32 during rotation. When the outer ring 32 rotates, certain portions of the irregular plate 322's edge regularly contact and push the second slide bar 6, causing the pressure block 61 on the second slide bar 6 to move regularly, pressing the rubber core and the PIN pin.

[0030] The wheel core 311 is located on the surface of the irregular plate 322 and within the wheel ring 321. The deflector 312 is a structural component embedded in the side of the wheel core 311 and controls the motion of the first slide bar 5. The second motor 4 is connected to the wheel core 311 and drives the rotation of the wheel core 311, providing a power source for the rotating wheel assembly 3. The first slide bar 5 is connected to the deflector 312. During rotation, the movement of the deflector 312 drives the first slide bar 5 in reciprocating mechanical motion, prompting the movable blade 51 on the first slide bar 5 to cut the material strip.

[0031] Reference Figure 2 In one embodiment of the present application, the processing mechanism further includes an optical fiber 7 arranged adjacent to the processing position 12 .

[0032] It's understandable that Fiber Optic 7 is primarily used to detect missing PIN pins in the material strip. The Fiber Optic 7 sensor boasts exceptionally high sensitivity and precision, accurately detecting missing PIN pins. This detection method is immune to electromagnetic interference, and particularly in high-precision production environments, the Fiber Optic 7 sensor provides stable and reliable detection results. In automated production lines, the rapid response of the Fiber Optic 7 sensor ensures smooth operation. If a missing PIN pin is detected in the material strip, the system can immediately sound an alarm or trigger a shutdown, preventing the missing component from being mistakenly inserted into subsequent processes. This avoids rework and waste caused by problems discovered in subsequent processes, improving production efficiency. Traditional manual inspections can lead to errors due to oversight or fatigue, while the automated detection capabilities of the Fiber Optic 7 sensor not only improve accuracy but also operate fully automatically around the clock, eliminating human interference and ensuring comprehensive and consistent detection.

[0033] Reference Figures 1 to 3 In one embodiment of the present application, the processing mechanism further includes a limiting plate 8 arranged on the top of the mounting frame 1 , and the first sliding rod 5 can abut against the limiting plate 8 .

[0034] As can be understood, the limit plate 8 is located at the top of the mounting frame 1, also at the processing position 12, and is used to limit the displacement of the first slide bar 5 to prevent excessive displacement, which may cause the movable knife 51 to damage the material or other components. The first slide bar 5 can contact this limit plate 8 during its movement. When the first slide bar 5 contacts the limit plate 8, the movement of the slide bar is restricted and cannot continue to exceed this position. Therefore, the limit plate 8 plays a "stop" or "limit" role here, thereby controlling the range of movement of the first slide bar 5 during the processing process and avoiding mechanical failure or incorrect processing operations.

[0035] Reference Figure 1 In one embodiment of the present application, the working surface 11 is further provided with a protective shell, which at least covers the wheel assembly 3.

[0036] It is understandable that the protective shell can completely cover the runner assembly 3, protecting the runner assembly 3 from contamination or damage from the external environment, such as preventing the entry of dust, oil, or other substances that may interfere with the normal operation of the runner assembly 3. At the same time, the protective shell may also prevent workers from coming into contact with high-speed rotating parts, thereby improving the safety of the equipment. In automated equipment, components such as the runner are usually located on the working surface 11 and may be affected by frequent operations and environmental conditions. Therefore, using a protective shell to cover them can ensure the normal operation of the runner assembly 3, extend its service life, and avoid equipment failures or accidents.

[0037] This utility model utilizes an integrated structural design to automate the assembly and cutting of the rubber core, PIN insertion, and material strips. The rubber core is fed to the workstation via a turntable, and the PIN pin strip is automatically loaded by the first motor 23. During operation, the second motor 4 drives the wheel assembly 3, achieving the upward and downward clamping motion of the dual slide bars. This sequentially completes the rubber core positioning, PIN insertion, and strip cutting, completing the assembly of the rubber core and PIN pins in one operation. The entire mechanism is compact and rationally laid out, utilizing a process integration approach to improve processing efficiency. This reduces the number of control units, ensuring processing accuracy while reducing electrical costs.
