[0003] The PIN pin of the terminal is a metal material used in the plastic core to complete the conduction (transmission) of electricity (signals). The PIN pin of the terminal needs to be assembled with the plastic core in one of the links of the manufacturing process, usually by plug-in. Cut the conjoined PIN into a single set of PINs, and insert the single set of PINs into the jack on the insulating base of the plastic core through a press-in mechanism.

[0004] After completing the above steps, it is necessary to cut off the material strip connected to the pins through the material edge folding mechanism. The prior art uses a cylinder to reciprocate to drive the eccentric wheel to rotate, thereby generating high-frequency vibration, so that the clamping blocks on the material edge folding mechanism cut inward to the two sides of the pins of the connected PIN, and the material strip is broken from the pin cutting position through high-frequency vibration. However, the above technology has the problem of fixed vibration frequency, so that the output of the material edge folding mechanism per hour is fixed, and the cylinder has a stroke that is not in place during the reciprocating motion, resulting in the clamping blocks being unable to apply sufficient force to the two sides of the pins, resulting in the vibration being unable to separate the material strip from the pins. Therefore, the applicant has made a beneficial design and found a solution to the above problem. The technical solution to be introduced below is produced in this context. Summary of the invention

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0039] Reference example Figures 1 to 4 A material edge folding mechanism comprises a frame 1 and a waste frame 2. The frame 1 is provided with a processing platform 3 which can move forward and backward. The processing platform 3 is provided with a servo motor 4 and a slider 5 which can move left and right. The rotating shaft of the servo motor 4 is provided with an adjustable eccentric block 41. The eccentric block 41 is provided with an action portion 42 and abuts against the slider 5. The slider 5 is provided with a lifting assembly 6. The lifting assembly 6 is provided with a cutting assembly 7. The waste frame 2 is arranged below the cutting assembly 7.

[0040] It is worth mentioning that first guide rails 11 are provided on both sides of the frame 1, the frame 1 is provided with a first cylinder 12, the piston rod of the first cylinder 12 is connected to the processing platform 3, the frame 1 is provided with a limit plate 13, the limit plate 13 is threadedly connected with an adjusting rod 14, the first guide rail 11 provides a guiding function for the processing platform 3 to move forward and backward, the first cylinder 12 drives the processing platform 3 to move forward and backward, so that the clamping block 72 moves to a specified position, and the limit plate 13 is used in conjunction with the adjusting rod 14. The movable distance of the processing platform 3 retracting is adjusted by the adjusting rod 14, thereby shortening the time required for the processing platform 3 to move forward and accelerating production efficiency;

[0041] It is worth mentioning that the processing platform 3 is slidably arranged on the first guide rail 11 and abuts against the adjustment rod 14. The processing platform 3 is provided with a second guide rail 31. The processing platform 3 provides a processing table for the servo motor 4, the cutting assembly 7, and the lifting assembly 6. The second guide rail 31 reduces the resistance of the slider 5 to move left and right.

[0042] It is worth mentioning that the slider 5 is slidably arranged on the second guide rail 31, and abutment blocks 51 are arranged on both sides of the slider 5. The abutment blocks 51 are provided with grooves 511 with openings. A support frame 52 is arranged below the slider 5. The groove 511 bears the eccentric force from the action part 42, thereby causing the slider 5 to move left and right on the second guide rail 31. The support frame 52 provides a fixing point for the lifting assembly 6.

[0043] It is worth mentioning that the servo motor 4 is installed and fixed on the processing platform 3. The rotating shaft of the servo motor 4 is provided with an induction wheel 43 and an adjustment block 44 in sequence. The servo motor 4 is provided with a sensor 45 and is used to detect the induction wheel 43. The adjustment block 44 is provided with a concave cavity 441. The concave cavity 441 is provided with a plurality of mounting holes 442. The induction wheel 43 is detected by the sensor 45, so that the rotation speed of the rotating shaft can be observed in real time on a visual screen. The concave cavity 441 allows the eccentric block 41 to be adjusted therein. The eccentric block 41 is displaced more to one side than to the other side according to the mounting holes 442, thereby changing the vibration amplitude of the slider 5. Since the adjustment block 44 itself is not on the same axis as the rotating shaft, when the eccentric wheel and the adjustment block 44 are on the same axis, the rotating shaft of the servo motor 4 rotates so that the slider 5 is at a normal vibration frequency.

[0044] It is worth mentioning that the eccentric block 41 is threadedly connected to the mounting hole 442 by screws, so that the eccentric block 41 is fixed in the concave cavity 441, and the action portion 42 is arranged in the groove 511 and abuts against both sides of the groove 511, and the adjusted eccentric block 41 is fixed by screws;

[0045] It is worth mentioning that the lifting assembly 6 includes a second cylinder 61 and a movable plate 62. The second cylinder 61 is installed and fixed on the support frame 52. The piston rod of the second cylinder 61 is connected and fixed to the movable plate 62. The movable plate 62 passes through the slider 5. A limit block 63 is provided on one side of the movable plate 62. The second cylinder 61 provides an upward or downward driving force for the movable plate 62, so that the clamping block 72 can incise the pins of the two groups of conjoined PINs of the same rubber core, so that this product can meet different processing requirements. The limit block 63 limits the movable distance of the movable plate 62 to fall.

[0046] It is worth mentioning that the cutting assembly 7 includes a fixing block 71 and a clamping block 72. The fixing block 71 is installed and fixed on one side of the movable plate 62. The fixing block 71 is provided with a third guide rail 73. Guide blocks 74 are provided on both sides of the third guide rail 73 and abut against each other. The clamping block 72 is installed and fixed on the guide block 74. The clamping blocks 72 abut against each other. A chamfer 721 is provided at the material inlet of the clamping block 72. A clamping portion 722 is provided at the material outlet of the clamping block 72. The guide rail provides a guiding function for the guide block 74. The chamfer 721 facilitates the material strip of the conjoined PIN to enter between the clamping blocks 72. The clamping portion 722 applies a force on both sides of the pins of the conjoined PIN to make them incise, thereby reducing the connection strength between the pins and the material strip, so that the material strip is affected by the vibration force and breaks from the incised part of the pins.

[0047] It is worth mentioning that the waste frame 2 is provided with a first shielding portion 21, and is arranged opposite to the cutting assembly 7. The first shielding portion 21 is provided with a second shielding portion 22 extending outward on both sides. The first shielding portion 21 and the second shielding portion 22 prevent the material strip of the connected PIN from splashing to the vicinity of the folding edge mechanism due to vibration force. The above design can better collect the waste strip.

[0048] The working principle of the utility model is now described as follows:

[0049] When the material strip of the connected PIN of the plug-in is inserted between the clamping blocks 72 from the chamfer 721, the guide block 74 is displaced to both sides of the third guide rail 73 to allow the material strip to enter. At this time, the material strip is located at the clamping portion 722, and the piston rod of the first cylinder 12 is extended to push the processing platform 3 forward, so that the clamping portion 722 moves to the position where the pin needs to be inscribed;

[0050] The servo motor 4 runs, driving the action part 42 and the eccentric block 41 to rotate. The eccentric force is transmitted to the groove 511 through the action part 42, causing the slider 5 to reciprocate to the left or right, thereby causing the slider 5 of the third guide rail 73 to move outward or toward the center. When the clamping block 72 moves toward the center of the third guide rail 73, the clamping part 722 applies an incision force to the pin, leaving a notch at the incision of the pin, reducing the connection strength between the material strip and the pin. The displaced clamping block 72 drives the material strip to fold left and right, thereby causing the material strip to separate from the pin and fall into the waste frame 2.

[0051] When the material strip processing is completed, the piston rod of the second cylinder 61 extends to drive the movable plate 62 to rise, so that the clamping part 722 moves to the material strip of another group of conjoined PINs of the same core, and performs the separation step for the material strip here.

[0052] The above design scheme can make the product have the advantages of adjustability, stable production and good practicality.

[0053] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
