Detailed Implementation

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings, but this utility model is not limited to the following embodiments.

[0017] When producing plastic parts with metal inserts, the strip of metal inserts must be kept continuous after metal stamping.

[0018] However, since metal terminals are often irregularly shaped and complex, ordinary feeding mechanisms are difficult to position accurately, necessitating the customization of specialized feeding mechanisms. Therefore, developing a versatile feeding mechanism that can adapt to various irregularly shaped terminals is crucial to improving production flexibility and reducing costs.

[0019] To address the aforementioned issues, this embodiment provides a universal feeding mechanism for producing plastic parts with metal inserts. The mechanism feeds the metal insert strip after stamping and maintains its continuity. The feeding mechanism includes a clamping assembly for holding the strip, a translation assembly connected to the clamping assembly for translating the clamping assembly, and a translation driver 11 for driving the translation assembly. The clamping assembly includes strip grippers 14 for holding the strip and a position adjustment module for adjusting the position of the strip grippers 14. The translation assembly includes a translation track 12 and a translation slider 13 mounted on the translation track 12. The translation track 12 provides guidance for the movement of the translation slider 13. The translation slider 13 is connected to the clamping assembly and drives the clamping assembly to translate along the length of the translation track 12. After the clamping assembly clamps the strip, the translation driver 11 drives the translation slider 13 to move forward along the translation track 12 to convey the strip forward. Then the clamping assembly releases the strip, and the translation driver 11 drives the translation slider 13 to move in the opposite direction along the translation track 12 to reset. The position adjustment module is used to adjust the position of the strip clamping claw 14 to adapt to irregularly shaped strips of different shapes.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 As shown, the strip is a long, continuous arrangement of metal stamping parts. To achieve automated production, a feeding mechanism is used to automatically move the strip forward to the next process. A clamping assembly is used to hold the strip before it is conveyed forward, facilitating its forward transport. A translation assembly is used to drive the reciprocating movement of the clamping assembly.

[0021] In its implementation, the feeding mechanism also includes a controller. The controller receives control signals that control the clamping assembly to perform clamping and releasing actions, and also controls the translation mechanism to move forward and backward. After the clamping assembly clamps the material strip, the translation mechanism conveys the strip forward. Then, the clamping assembly releases the strip, and the translation mechanism moves backward to reset, completing one cycle. Multiple cycles can continuously convey the material strip forward.

[0022] In the actual implementation process, different material strips have different shapes and sizes. In order for the feeding mechanism to adapt to different material strips, the position adjustment module can adjust the position of the clamping component so that the feeding mechanism can adapt to different material strips.

[0023] Furthermore, the clamping assembly includes two strip clamps 14, which are respectively disposed on both sides of the strip width direction. When the clamping assembly clamps the strip, the two strip clamps 14 clamp the strip simultaneously on both sides of the strip width direction, ensuring that the strip movement direction is parallel to the length direction of the translation track 12.

[0024] In this embodiment, the clamping assembly includes two strip grippers 14, which are respectively disposed on both sides of the strip width direction. When conveying the strip forward, the two strip grippers 14 simultaneously clamp the strip from both sides and pull it forward synchronously, which can ensure that the strip moves in parallel and has higher stability than a single strip gripper 14 pulling the strip from one side.

[0025] Furthermore, the material strip gripper 14 includes two gripping blocks 141 and a gripper driver 142 that drives the two gripping blocks 141 to move relative to each other; the gripper driver 142 can drive the two gripping blocks 141 to move towards each other until the material strip between the two gripping blocks 141 is clamped, and the gripper driver 142 can also drive the two gripping blocks 141 to move away from each other until the material strip between the two gripping blocks 141 is released.

[0026] In this embodiment, the material strip gripper 14 uses two movable clamping blocks 141 to achieve clamping and releasing actions. The gripper driver 142 can be a pneumatic cylinder, an electric cylinder, or a linear motor. A guide mechanism is also provided between the two clamping blocks 141 to restrict the two clamping blocks 141 to move only in the direction of approaching or moving away from each other.

[0027] Furthermore, a spatial rectangular coordinate system is established in the space where the feeding mechanism is located. The spatial rectangular coordinate system includes mutually perpendicular X-axis, Y-axis, and Z-axis. The length direction of the translation track 12 is parallel to the Y-axis, and the Z-axis is the direction of metal stamping. The position adjustment module includes an X adjustment unit that can adjust the position of the strip clamp 14 along the X-axis and a Z adjustment unit that can adjust the position of the strip clamp 14 along the Z-axis.

[0028] In this embodiment, the Y-axis is the direction of strip movement, the Z-axis is the direction of metal stamping, and also the direction of strip clamping and releasing by the strip gripper 14. The X-axis is the direction perpendicular to the Y-axis and Z-axis in the spatial rectangular coordinate system.

[0029] The position adjustment module includes an X-adjustment unit capable of adjusting the position of the strip clamping jaws 14 along the X-axis and a Z-adjustment unit capable of adjusting the position of the strip clamping jaws 14 along the Z-axis. The X-adjustment unit can adjust the distance between the two strip clamping jaws 14 according to the width of the strip to accommodate strips of different widths. The Z-adjustment unit can adjust the height of the strip clamping jaws 14 to accommodate strips of different thicknesses or to adapt the strip position to molds of different heights.

[0030] Furthermore, the X-adjustment unit includes an X-adjustment fixed block 21, an X-adjustment movable block 22, and an X-locking mechanism 23. The X-adjustment fixed block 21 and the X-adjustment movable block 22 are respectively provided with matching sliding grooves and sliders, which restrict the X-adjustment fixed block 21 and the X-adjustment movable block 22 to move relative to each other only along the X-axis direction. The X-locking mechanism 23 is used to fix and release the relative position of the X-adjustment fixed block 21 and the X-adjustment movable block 22. When the X-locking mechanism 23 is in the locked state, the relative position of the X-adjustment fixed block 21 and the X-adjustment movable block 22 remains fixed. When the X-locking mechanism 23 is in the released state, the relative position of the X-adjustment fixed block 21 and the X-adjustment movable block 22 can be adjusted. The X-adjustment movable block 22 is connected to the material belt clamp 14, and the X-adjustment fixed block 21 is connected to the translation slider 13.

[0031] In this embodiment, as Figure 5 As shown, the slide and slider are dovetail-shaped, and the dovetail-shaped slider and slide can restrict the slider and slide to move only along the length direction of the slide.

[0032] The X locking mechanism 23 can be a threaded hole set on the X adjusting fixed block 21 and a bolt installed in the threaded hole that matches the thread. Rotating the bolt can make the bolt pass through the slide groove and squeeze the slider, thereby increasing the friction between the slide groove and the slider; rotating the bolt in the opposite direction can release the movement between the slider and the slide groove.

[0033] Furthermore, the Z-adjustment unit includes a Z-adjustment fixed block 24, a Z-adjustment movable block 25, and a Z-locking mechanism 26. The Z-adjustment fixed block 24 and the Z-adjustment movable block 25 are respectively provided with matching sliding grooves and sliders, which restrict the Z-adjustment fixed block 24 and the Z-adjustment movable block 25 to move relative to each other only along the Z-axis direction. The Z-locking mechanism 26 is used to fix and release the relative position of the Z-adjustment fixed block 24 and the Z-adjustment movable block 25. When the Z-locking mechanism 26 is in the locked state, the relative position of the Z-adjustment fixed block 24 and the Z-adjustment movable block 25 remains fixed. When the Z-locking mechanism 26 is in the released state, the relative position of the Z-adjustment fixed block 24 and the Z-adjustment movable block 25 can be adjusted. Z-adjustment movable block 25 is connected to X-adjustment fixed block 21, and Z-adjustment fixed block 24 is connected to translation slider 13.

[0034] The Z-adjustment fixed block 24, Z-adjustment movable block 25, and Z-locking mechanism 26 are similar to the X-adjustment fixed block 21, X-adjustment movable block 22, and X-locking mechanism 23. The slide and slider are dovetail-shaped, and the dovetail-shaped slider and slide can restrict the slider and slide to move only along the length of the slide.

[0035] In the specific implementation process, the X-adjustment fixed block 21 is connected to the sliding rail, the X-adjustment movable block 22 is connected to the Z-adjustment fixed block 24, and the Z-adjustment movable block 25 is connected to the clamping driver.

[0036] Furthermore, the feeding mechanism also includes a strip support roller 27 disposed between the two strip grippers 14 and a material support roller 28 disposed at one end of the strip support roller 27; the strip support roller 27 is used to support the strip between the two strip grippers 14; the material support roller 28 is used to support and guide the strip at the end of the strip support roller 27 away from the strip grippers 14.

[0037] In this embodiment, the strip support roller 27 is a long strip-shaped component with its length direction parallel to the Y direction, used to support the strip. The support roller 28 is a roller component with its axial direction parallel to the X direction, located at the end of the strip support roller 27 away from the strip gripper 14, and serves to support the strip. In some embodiments, the strip is in a wound state, and the wound strip can change its extension direction by passing through the support roller 28, thereby serving a guiding function.

[0038] Furthermore, the feeding mechanism also includes a mold fixing plate 31, which is used to connect the metal stamping mold; The strip support roller 27 is connected to the mold fixing plate 31. An X adjustment module 32 for adjusting the strip support roller 27 along the X-axis and a Z adjustment module 33 for adjusting the position of the strip support roller 27 along the Z-axis are provided between the strip support roller 27 and the mold fixing plate 31.

[0039] In this embodiment, the mold fixing plate 31 is provided with mounting holes for connecting with the stamping mold via fasteners.

[0040] The X-adjustment module 32 and Z-adjustment module 33 are similar to the X-adjustment unit and Z-adjustment unit, including an adjustment fixed block, an adjustment movable block, and a locking mechanism. The X-adjustment module 32 can adapt to the width adjustment of the material strip, and the Z-adjustment module 33 can adapt to the thickness adjustment of the material strip or the position of the material strip in the height direction.

[0041] Furthermore, the translation driver 11 is a servo motor.

[0042] In this embodiment, the servo motor can stably and accurately control the movement of the translation slider 13 on the translation track 12.

[0043] Furthermore, at least two position sensors 34 are provided on the translation track 12, and a positioning unit 35 matching the position sensors 34 is provided on the translation slider 13. When the translation driver 11 drives the translation slider 13 to move on the translation track 12, the position sensors 34 and the positioning unit 35 are used to control the position of the translation slider 13.

[0044] In this embodiment, the position sensor 34 and the positioning unit 35 are a set of matching U-shaped groove photoelectric switches. The position sensor 34 can be adjusted on the sliding track by the connector, thereby realizing the adjustment of the starting point, ending point and travel distance of the moving position each time the material belt is moved.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
