[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0045] In the embodiment of the present invention, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. 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.

[0047] It is worth mentioning that the transport component 2 includes a guide plate 21, a sealing plate 22, and a servo motor 23. The guide plate 21 is provided with a groove 211 that can accommodate the PIN pins of the conjoined terminal. The shaft of the servo motor 23 is provided with a gear 24. The gear teeth of the gear 24 pass through the guide plate 21 and engage the PIN pins of the conjoined terminal. The sealing plate 22 covers the top of the guide plate 21 and keeps a distance from the conjoined part of the PIN pins of the conjoined terminal. The sealing plate 22 is provided with a first through hole 221. The groove 211 provides a guide for the conjoined PIN. The conjoined part of the conjoined PIN has holes corresponding to the gear teeth of the gear 24. Therefore, when the gear 24 rotates, the gear 24 enters the hole and pushes the conjoined PIN forward. The sealing plate 22 only covers the conjoined part of the conjoined PIN, but does not cover the pins of the conjoined PIN to prevent the pins of the conjoined PIN with a bent part from being pressed and bent.

A chamfer 441 is provided at the feeding position of the cutting knife 44. The other end of the linkage plate 43 abuts against the cutting knife 44. The force of the cutting cylinder 41 is transmitted to the cutting knife 44 through the linkage plate 43. When the cutting knife 44 is pressed down, it not only fixes the conjoined PIN, but also cuts off the conjoined part connected to the pin of the conjoined PIN by the cutter 341. When the cutting cylinder 41 is retracted, since the cutting knife 44 has no downward pressure, the conjoined PIN enters the subsequent process along the chamfer 441.

The abutment portion 54 cooperates with the first limiting portion 11 and the second limiting portion 12. When the bearing platform 53 is not moving, the abutment portion 54 abuts against the first limiting portion 11.

[0052] It is worth mentioning that the material dividing assembly 6 includes a material dividing cylinder 61, a base plate 62, a first transfer plate 63, and a first pressing plate 64. The base plate 62 is installed and fixed on the carrier 53. The base plate 62 is provided with a first support plate 65 and a first guide column 66.

The base plate 62 is provided with a first pressure-bearing surface 621 and is located below the first pressing plate 64. The first guide column 66 provides a guiding function for the first pressing plate 64. The dividing knife 67 cuts off the connected part of the pins of the conjoined PIN by the cutting knife 341. The plug block 8 provides a supporting force for the PIN pins of the terminal to be inserted into the hole of the rubber core. The force of the piston rod of the dividing cylinder 61 is transmitted to the first pressing plate 64 through the first transfer plate 63, so that the first pressing plate 64 moves up or down. The first pressure-bearing surface 621 provides a bearing force for the conjoined PIN.

[0053] It is worth mentioning that the offset material displacement assembly 7 includes a material pressing cylinder 71, a material moving cylinder 72, a second guide rail 73, a movable plate 74, a second material pressing plate 75, and a second transfer plate 76.

The second guide post 78 provides a guiding effect for the second pressing plate 75. The second pressing plate 75 presses the conjoined PIN tightly against the second pressure-bearing surface 741. The force of the piston rod of the pressing cylinder 71 is transmitted to the second pressing plate 75 through the second transmission plate 76, so that the second pressing plate 75 moves up or down. When the material transfer cylinder 72 is not running, the second pressing plate 75 and the first pressing plate 64 maintain the spacing between the pins of the cutter 341 that cuts the conjoined PIN, thereby facilitating the material dividing knife 67 to cut the conjoined part of the conjoined PIN.

[0054] The number of multiple groups is set to two.

[0055] The use principle of the utility model is now described as follows:

[0056] The conjoined PIN is placed in the groove 211, and the hole of the conjoined part of the conjoined PIN is embedded in the gear teeth of the gear 24. As the servo motor 23 runs and drives the gear 24 to rotate, the conjoined PIN is driven to move. Every time the conjoined PIN moves a certain distance, the residual material cylinder 32 runs and pushes the residual material block 34 to sink, and the cutter 341 cuts off the pins of the conjoined PIN.

[0057] When the pins of the cut-off conjoined PIN enter the first pressure-bearing surface 621 and the second pressure-bearing surface 741, the piston rod of the cutting cylinder 41 extends, and transmits the force to the cutting knife 44 through the linkage plate 43. The linkage plate 43 applies downward pressure to the cutting knife 44, so that the cutting knife 44 is pressed down. The first pair of the conjoined PIN is fixed to prevent the conjoined part of the conjoined PIN from being deformed during the cutting process, and the second pair of the cutting knives 341 cuts off the conjoined part connected by the pins of the conjoined PIN for cutting, thereby obtaining a whole section of the conjoined PIN;

[0058] When the cutting cylinder 41 is running, the piston rods of the dividing cylinder 61 and the pressing cylinder 71 extend out, and the extending force acts on the base plate 62 and the movable plate 74 respectively, thereby causing the first transfer plate 63 and the second transfer plate 76 to rotate, and transmit the force to the first pressing plate 64 and the second pressing plate 75 respectively, and the first pressing plate 64 and the second pressing plate 75 sink, and press the whole section of the connected PIN tightly against the first pressure-bearing surface 621 and the second pressure-bearing surface 741, and fix the connected PIN, the insert block 8 is first inserted between the pins of the connected PIN, and then the dividing knife 67 and the cutting knife 44 separate and cut the connected PIN at the same time, and the dividing knife 67 divides the whole section of the connected PIN into two;

[0059] The piston rod of the material transfer cylinder 72 is retracted, and a set of connected PINs on the second pressure-bearing surface 741 is kept at a distance from a set of connected PINs on the first pressure-bearing surface 621, so as to adapt to the hole position of the rubber core;

[0060] The piston rod of the plug-in assembly 5 extends out, driving the material dividing assembly 6 and the offset material displacement assembly 7 to move simultaneously until the pin of the one-piece PIN is inserted into the hole of the rubber core. At this time, the abutment portion 54 abuts against the second limiting portion 12 to prevent the support platform 53 from continuing to move. At this point, the operation steps of cutting, breaking, splitting, offsetting and inserting the one-piece PIN are completed.

[0061] The above design scheme can enable the product to achieve the advantages of improving production efficiency, reducing overall volume, and improving resource utilization.

[0062] 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.
