Description

Technical Field

[0001] This utility model relates to the field of terminal strip cutting technology, and in particular to a compact terminal strip cutting mechanism. Background Technology

[0002] As the level of automation in the electronics manufacturing industry continues to increase, the pin insertion operation of terminals and connectors on PCBs is gradually shifting from manual operation to fully automated high-speed assembly. In this type of automatic pin insertion equipment, the fixed-length cutting of terminal strips is a preliminary step in the pin insertion process, and its structural layout and operating cycle directly affect the overall machine operating efficiency and assembly stability.

[0003] In existing technologies, most terminal cutting devices use a cylinder-driven method, where the upper or lower blade is horizontally reciprocated by the cylinder to cut the terminal strip. Although this type of structure is simple to operate, the large length of the cylinder body and the large space required for its stroke result in the overall cutting mechanism occupying a significant amount of installation space in the lateral dimension. This is particularly problematic in compact equipment layouts or multi-channel synchronous pin insertion operations, easily leading to spatial conflicts and structural interference, severely hindering the development of compact and modular equipment.

A clearance space 13 for avoiding the pin and the terminal strip 70 is provided between the first receiving area 11 and the second receiving area 12. The terminal strip 70 is located along the second horizontal direction ( Figure 3 The upper blade holder 30 is slidably disposed in the first receiving area 11 along the first horizontal direction. The upper cutting blade module 40 is disposed on the upper blade holder 30 and the cutting end of the upper cutting blade module 40 is close to the clearance space 13. The lower blade holder 50 is slidably disposed in the second receiving area 12 along the first horizontal direction. The lower cutting blade 60 is disposed at one end of the lower blade holder 50 close to the clearance space 13. The drive assembly 20 is disposed on one side of the mounting base 10 along the second horizontal direction. The drive end of the drive assembly 20 is connected to the upper blade holder 30 and the lower blade holder 50. The drive assembly 20 is configured to drive the upper blade holder 30 and the lower blade holder 50 to move closer to or further away from each other along the first horizontal direction.

[0036] Specifically, the upper cutter holder 30 and the lower cutter holder 50 are brought close to each other so that the upper cutter 41 and the lower cutter 60 are closed, and the upper cutter holder 30 and the lower cutter holder 50 are moved away from each other so that the upper cutter 41 and the lower cutter 60 are separated, so as to achieve the cutting of the terminal material strip 70.

[0037] Specifically, the first horizontal direction is perpendicular to the second horizontal direction.

[0038] By setting the drive assembly 20 on one side perpendicular to the moving direction of the upper cutter holder 30 and the lower cutter holder 50, the lateral space of the cutting mechanism is effectively saved while the terminal strip 70 is being cut, making the mechanism structure compact and improving the overall space utilization of the mechanism.

[0039] In one embodiment, the mounting base 10 has a first limiting notch 110 and a second limiting notch on a first side extending along a first horizontal direction. The first limiting notch 110 extends along the first horizontal direction, and a first connecting member 31 is fixedly provided on the side of the upper tool holder 30 near the first limiting notch 110. The first connecting member 31 passes through the first limiting notch 110, and the first limiting notch 110 is configured to limit the upper tool holder 30 along the first horizontal direction. The second limiting notch extends along the first horizontal direction, and a second connecting member 51 is fixedly provided on the side of the lower tool holder 50 near the first limiting notch 110. The second connecting member 51 passes through the second limiting notch, and the second limiting notch is configured to limit the lower tool holder 50 along the first horizontal direction.

[0040] By setting the first limiting notch 110, the second limiting notch, the first connecting piece 31 and the second connecting piece 51 in cooperation, the upper knife holder 30 and the lower knife holder 50 are limited and guided in the first horizontal direction, which helps to maintain the stability of the cutting motion and the accuracy of the cutting.

[0041] In one embodiment, the drive assembly 20 includes a first drive member, a second drive member, a track plate, a first follower 21, and a second follower 22, wherein: the track plate includes a first track groove and a second track groove; the first follower 21 passes through the first track groove; the drive end of the first drive member is connected to the first end of the first follower 21; the second end of the first follower 21 is connected to the first connector 31; the first drive member is configured to drive the first connector 31 to reciprocate within the first limiting notch 110 in a first horizontal direction via the first follower 21, so as to synchronously drive the upper tool holder 30 to reciprocate within the first horizontal direction; the second follower 22 passes through the second track groove; the drive end of the second drive member is connected to the first end of the second follower 22; the second end of the second follower 22 is connected to the second connector 51; the second drive member is configured to drive the second connector 51 to reciprocate within the second limiting notch in a first horizontal direction via the second follower 22, so as to synchronously drive the lower tool holder 50 to reciprocate within the first horizontal direction.

[0042] Specifically, the first connector 31 and the second connector 51 have the same structure, the first follower 21 and the second follower 22 have the same structure, the first connector 31 and the first follower 21 interfere with each other along the first horizontal direction, and the second connector 51 and the second follower 22 interfere with each other along the first horizontal direction.

[0043] By adopting a driving method that links the track plate and follower mechanism with the driving component, and by connecting with the first connecting member 31 and the second connecting member 51, the upper tool holder 30 and the lower tool holder 50 are driven at the same time, and the lateral space of the mounting base 10 extending along the first horizontal direction is effectively utilized.

[0044] In one embodiment, the upper cutting module 40 includes a plurality of upper cutting blades 41, which extend along a first horizontal direction and are spaced apart at a preset interval along a second horizontal direction.

[0045] Specifically, the upper cutting module 40 includes three upper cutting blades 41.

[0046] By setting multiple upper cutting blades 41 and arranging them at equal intervals along the horizontal direction, multiple rows of terminal strips 70 can be cut simultaneously, improving the parallel processing capability of the equipment and enhancing the overall machine operation efficiency.

[0047] In one embodiment, the upper blade holder 30 is provided with a stripping block 32 at one end near the terminal strip 70 along the first horizontal direction. The stripping block 32 is slidably disposed in the first receiving area 11. The upper cutter 41 is disposed through the stripping block 32 at one end near the terminal strip 70. The stripping block 32 is configured to cooperate with the upper cutter 41 to separate the terminal strip 70 from the upper cutter 41.

[0048] By setting a sliding stripping block 32, the upper cutter 41 passes through the stripping block 32 and acts on the terminal strip 70, which can help the terminal strip 70 to get off the cutter, effectively avoiding the jamming of the cutter or the adhesion of residual material after cutting, and improving the smoothness of material output and cutting efficiency.

[0049] In one embodiment, the compact terminal strip cutting mechanism further includes several sets of pre-compression components 80, which are spaced apart on the upper cutter holder 30 along the vertical plane of the second horizontal direction. The pre-compression components 80 are configured to pre-compress and fix the terminal strip 70 before cutting.

[0050] By pre-pressing and fixing the terminal strip 70 with multiple pre-pressing components 80, it is helpful to stably position the strip before cutting, prevent the strip from moving during the cutting process, and improve the cutting alignment accuracy.

[0051] In one embodiment, the upper cutter holder 30 is provided with a third receiving area. The third receiving area is provided with a plurality of through holes at one end near the stripping block 32. A stop block 33 is fixedly provided at one end of the upper cutter holder 30 away from the terminal strip 70. The third receiving area is in contact with the stop block 33. Each pre-pressing assembly 80 includes a spring 81 and a pre-pressing rod 82. The spring 81 and the pre-pressing rod 82 are coaxially arranged along a first horizontal direction. The first end of the spring 81 abuts against the stop block 33. The second end of the spring 81 is connected to the first end of the pre-pressing rod 82. The pre-pressing rod 82 passes through the corresponding through hole and is slidably disposed in the stripping block 32. The spring 81 provides elastic force to move the pre-pressing rod 82 in the stripping block 32 until it abuts against the inner wall of the stripping block 32 near the end of the terminal strip 70. Then the upper cutter holder 30 continues to move so that the stripping block 32 presses against the terminal strip 70.

[0052] The combination of spring 81, preload rod 82 and stripping block 32 provides a cutting assembly that is stable in operation and can be adaptively adjusted.

[0053] In one embodiment, a lower blade pad 52 is fixedly disposed inside the lower blade holder 50 and the lower blade pad 52 is located at one end of the lower blade holder 50 away from the terminal material strip 70 along the first horizontal direction. An air passage is disposed inside the lower blade pad 52. The air outlet of the air passage faces the lower cutter 60, and the air inlet of the air passage is connected to an external air source. The external air source blows air toward the air passage to blow out the waste material cut by the lower cutter 60.

[0054] Specifically, the air inlet of the airway is connected to an external air source via a miniature connector 520.

[0055] By setting a lower blade pad 52 with an air passage in the lower blade holder 50 and using an air source to blow air, waste material can be quickly discharged from the cutting area after cutting, preventing waste material accumulation from affecting the blade movement and effectively improving the cleanliness of the cutting area and the efficiency of automated operation.

[0056] In one embodiment, a first baffle 14 and a second baffle 15 are provided on the second side of the mounting base 10 extending along a first horizontal direction. The first baffle 14 and the second baffle 15 are spaced apart along the first horizontal direction. The first receiving area 11 contacts the first baffle 14, and the first baffle 14 is configured to limit the upper tool holder 30 along the second horizontal direction. The second receiving area 12 contacts the second baffle 15, and the second baffle 15 is configured to limit the lower tool holder 50 along the second horizontal direction.

[0057] By setting a baffle on the mounting base 10 to limit the movement of the upper knife holder 30 and the lower knife holder 50 along the second horizontal direction, the lateral positioning stability of the knife holder is improved, lateral deviation is prevented during cutting, and the overall motion accuracy and lifespan of the device are improved.

[0058] In one embodiment, a first pad 16 and a second pad 17 are spaced apart on the mounting base 10 along a first horizontal direction, wherein: the first pad 16 is disposed at the top of the first receiving area 11 and extends along the first horizontal direction, and the top surface of the upper tool holder 30 contacts the first pad 16; the second pad 17 is disposed at the top of the second receiving area 12 and extends along the first horizontal direction, and the top surface of the lower tool holder 50 contacts the first pad 16.

[0059] By setting a first pad 16 and a second pad 17 on the mounting base 10 and having them contact the top surface of the cutter holder, frictional resistance can be effectively reduced, wear on the cutter holder can be reduced, and the cutter holder can be ensured to slide stably within the receiving area, thereby enhancing the operational reliability and structural life of the cutting system.
