Detailed Implementation

[0010] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0011] A board terminal is formed by connecting multiple terminals, with adjacent terminals connected by one or more connecting structures. Before use, a cutter on a cutting device needs to cut the connecting structure between adjacent terminals to separate the connected terminals, facilitating the gripping of each terminal before installation onto the connector. However, when the cutter on the cutting device cuts the board terminal, stress release can cause the terminal to become misaligned. Alternatively, the cutter itself has a certain thickness, and when cutting the connecting structure between adjacent terminals, it pushes the two terminals horizontally to both sides, causing misalignment of both terminals and their connected terminals. Further cutting of the terminals with the cutter may result in over-cutting due to the changed terminal position, potentially damaging the terminals.

[0012] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a terminal cutting device, including a carrier 10 and a first cutter 30.

[0013] The carrier 10 has a carrying area 11 for carrying a plurality of terminals 20 spaced apart along a first direction X. The first cutting member 30 includes a body portion 31 and a guiding portion 32. The body portion 31 is disposed on one side of the carrier 10 along a third direction Z, and the guiding portion 32 is disposed on the side of the body portion 31 facing the carrier 10. The guiding portion 32 is used to be embedded between two adjacent terminals 20. The guiding portion 32 includes a first guide surface 321 and a second guide surface 322 disposed opposite to each other along the first direction X. The distance between the first guide surface 321 and the second guide surface 322 gradually decreases along the direction from the body portion 31 to the carrier 10. Wherein, the first direction X is the length direction of the carrier 10, the third direction Z is the height direction of the carrier 10, and the first direction X and the third direction Z intersect.

[0014] It is understood that a conveying structure, such as a conveyor belt or conveyor roller, can be provided within the carrying area 11 on the carrier 10, with the conveying direction of the conveying structure along the first direction X. Multiple connected terminals 20 can be placed on the conveying structure within the carrying area 11, and the conveying structure transports the multiple terminals 20 to the corresponding positions of the first cutter 30, facilitating the cutting of the connection between adjacent terminals 20 by the first cutter 30. A guide portion 32 on the first cutter 30 is located at the bottom end of the body 31. When the body 31 moves the guide portion 32 downwards, the guide portion 32 can be embedded between two adjacent terminals 20. Since the first guide surface 321 and the second guide surface 322 on the guide portion 32 are both inclined slopes, curved surfaces, or a combination of inclined and curved surfaces, and the distance L between the first guide surface 321 and the second guide surface 322 gradually decreases from top to bottom, the two guide surfaces can guide the guide portion 32 as it is embedded between the two terminals 20. Simultaneously, the guide part 32 can also correct the terminals 20 during the downward insertion process. If multiple terminals 20 are misaligned to a certain extent during transmission, after the bottom end of the guide part 32 is inserted between two adjacent terminals 20, the guide part 32 gradually moves downward, and its first guide surface 321 or second guide surface 322 contacts the terminal 20 and pushes the terminal 20 in the horizontal direction, so that the terminal 20 moves to the correct position. Then, the bottom end of the body part 31 contacts the connection point of the two terminals 20. A lower cutter is also provided inside the carrier 10. The position of the lower cutter corresponds to the position of the connection point of the two terminals 20. The lower cutter moves upward. When the lower cutter merges with the body part 31, it can cut the connection point of the two terminals 20 to separate the two adjacent terminals 20. The body part 31 can be regarded as the upper cutter.

[0015] The guide part 32 guides the cutting of the terminal 20, ensuring that the cutter cuts at the connection between the two terminals 20, avoiding overcutting of the terminal 20 and preventing the formation of metal wires. Since the cutting does not occur on the terminal 20, the blade edge is protected, increasing its lifespan and reducing the need for frequent blade replacements, thus lowering maintenance costs.

[0016] Please see Figure 2 and Figure 4 In conjunction with the above embodiments, in some embodiments, the maximum distance between the first guide surface 321 and the second guide surface 322 is equal to the distance between two adjacent terminals 20.

[0017] It is understood that there is a maximum distance between the first guide surface 321 and the second guide surface 322, which is the same as the thickness of the body portion 31, where the thickness of the body portion 31 is its dimension in the first direction X. When the guide portion 32 is inserted between two adjacent terminals 20, the first guide surface 321 and the second guide surface 322 can respectively contact the two adjacent terminals 20. At this time, the multiple connected terminals 20 are limited by the guide portion 32 and cannot move in the first direction X, which can further ensure the stability of the terminals 20 during cutting and avoid the position of the terminals 20 being offset by external factors during the cutting process. The contact between the first guide surface 321 and the second guide surface 322 and the two adjacent terminals 20 can also make the position of the guided terminals 20 more accurate, which is more conducive to the cutting of the cutter.

[0018] When multiple terminals 20 need to be cut, multiple first cutting blades 30 can be used. These first cutting blades 30 are moved downwards so that each terminal 20 is positioned between two adjacent first cutting blades 30. This effectively clamps the terminal 20 between the two adjacent first cutting blades 30, ensuring the stability of the terminal 20. When the connection between terminals 20 is cut by the main body 31 and the corresponding lower cutting blade, the clamping effect of the multiple first cutting blades 30 prevents the terminal 20 from shifting position during the cutting process, further ensuring the stability of the terminal 20 during cutting.

[0019] Please see Figure 3 , Figure 5 and Figure 6 In conjunction with the above embodiments, in some embodiments, the main body 31 is provided with two guide portions 32 on the side facing the carrier 10. The two guide portions 32 are arranged at intervals along the second direction Y. The main body 31 and the two guide portions 32 enclose a cutting area 33, which is used to accommodate the first connecting portion 40 between two adjacent terminals 20. Herein, the second direction Y is the width direction of the carrier 10, and the first direction X, the second direction Y, and the third direction Z intersect each other.

[0020] Understandably, two guide portions 32 are provided at the bottom of the main body 31. The two guide portions 32 are spaced apart along the second direction Y, and the two guide portions 32 and the bottom of the main body 31 together enclose the cutting area 33. The first connecting portion 40 is a connection structure between two adjacent terminals 20, which needs to be cut by a cutter. When the first cutter 30 moves downward, it can align the cutting area 33 at its bottom with the first connecting portion 40, so that the first connecting portion 40 is embedded inside the cutting area 33. At this time, the two guide portions 32 at the bottom of the main body 31 are respectively located on both sides of the first connecting portion 40 along the second direction Y. When the corresponding lower cutter merges with the bottom of the main body 31 to cut the first connecting portion 40, the position of these two guide portions 32 can ensure that the two adjacent terminals 20 always remain parallel, avoiding the terminals 20 from being affected by cutting stress or external factors, which could cause the position to become skewed. At the same time, the two guiding parts 32 are set, which is equivalent to increasing the guiding range, improving the guiding effect on the terminal 20, and ensuring the accuracy of the cutting position of the terminal 20.

[0021] Please see Figure 2 and Figure 5 In conjunction with the above embodiments, in some embodiments, the terminal cutting device further includes a positioning member 50, which is disposed on one side of the first cutter 30 in the second direction Y. The positioning member 50 is used to cooperate with the second connecting portion 60 between two adjacent terminals 20 to position the terminal 20.

[0022] Understandably, during the cutting process of terminal 20, the positioning element 50 can also be used to position terminal 20. For example... Figure 7 As shown, adjacent terminals 20 are connected by a first connecting portion 40 and a second connecting portion 60. The first connecting portion 40 and the second connecting portion 60 are arranged at intervals along the second direction Y. The positioning member 50 needs to cooperate with the second connecting portion 60, so the positioning member 50 is set on one side of the first cutter 30 along the second direction Y. The positioning member 50 can press the second connecting portion 60 downwards to ensure that the second connecting portion 60 has a certain stability, thus ensuring that the multiple terminals 20 have a certain stability and achieving a positioning effect. The positioning member 50 can also penetrate the second connecting portion 60 to prevent the second connecting portion 60 from moving horizontally, also ensuring that the multiple terminals 20 have a certain stability and achieving a positioning effect.

[0023] Please see Figure 5 and Figure 8 In conjunction with the above embodiments, in some embodiments, the positioning member 50 includes a vertical rod portion 51 and a conical portion 52.

[0024] The vertical rod portion 51 is used to be inserted into the positioning hole 61 on the second connecting portion 60. The conical portion 52 is provided on the side of the vertical rod portion 51 facing the support member 10.

[0025] Understandably, the conical portion 52 on the positioning member 50 is located at the bottom end of the vertical rod portion 51. The conical portion 52 has an inverted conical structure, which facilitates quick and easy insertion into the positioning hole 61 on the second connecting portion 60. When the conical portion 52 is inserted into the corresponding positioning hole 61, it can also play a certain guiding role for the multiple terminals 20. Since the surface of the conical portion 52 is curved and wider at the top than at the bottom, if the position of the multiple terminals 20 is deviated to a certain extent, the conical portion 52 will contact the inner wall of the positioning hole 61 during its descent and push the inner wall, thus correcting the position of the multiple terminals 20 to a certain extent and achieving a guiding effect. When the positioning member 50 continues to move downward until part of the vertical rod portion 51 is inserted into the positioning hole 61, the vertical rod portion 51 is exactly engaged with the positioning hole 61, which can prevent the multiple terminals 20 from moving horizontally due to external factors, ensuring that the multiple terminals 20 have a certain degree of stability and a good positioning effect.

[0026] The cross-sectional shape of the vertical rod 51 is the same as that of the positioning hole 61, which can be circular, rectangular, polygonal or irregular. Preferably, the cross-sectional shape of the vertical rod 51 and the cross-sectional shape of the positioning hole 61 are polygonal. When the two are connected, the multiple terminals 20 will not be affected by external forces and will not rotate.

[0027] Please see Figure 2 In conjunction with the above embodiments, in some embodiments, the terminal cutting device further includes a second cutting member 70, which is disposed on one side of the positioning member 50 along the first direction X, and is used to cut the second connecting portion 60.

[0028] It is understood that the first cutter 30 on the terminal cutting device is used to cut the first connecting portion 40, and the second cutter 70 is used to cut the second connecting portion 60. To avoid the terminal 20 from being misaligned, the first connecting portion 40 and the second connecting portion 60 are not cut simultaneously. The multiple terminals 20 are moved along the first direction X by the conveying structure until the first connecting portion 40 at the connection of the multiple terminals 20 is located directly below each of the first cutters 30, and at least part of the second connecting portion 60 is located directly below the positioning member 50. The positioning member 50 moves downward and is inserted into the positioning hole 61 on the second connecting portion 60 to position the multiple terminals 20. Then, the first cutter 30 is moved downward so that the guide portion 32 at the bottom of the first cutter 30 is inserted between two adjacent terminals 20, while the first connecting portion 40 is cut by the body portion 31 and the corresponding lower cutter.

[0029] After the first connecting part 40 is cut, the first cutting blade 30 and the positioning member 50 are moved upward so that they are separated from the multiple terminals 20 that need to be cut. Then, the multiple terminals 20 continue to move along the first direction X through the conveying structure until the second connecting part 60 at the connection of the multiple terminals 20 is located directly below each second cutting blade 70. The second cutting blade 70 moves downward and merges with the corresponding lower cutting blade to cut the corresponding second connecting part 60.

[0030] Please see Figure 1 and Figure 2 In conjunction with the above embodiments, in some embodiments, the terminal cutting device further includes a driving member 80, which is connected to the side of the support member 10 along the third direction Z. The first cutting member 30, the second cutting member 70 and the positioning member 50 are connected to the side of the driving member 80 facing the support member 10. The driving member 80 is used to drive the first cutting member 30, the second cutting member 70 and the positioning member 50 to move along the third direction Z.

[0031] Understandably, to ensure that the first cutter 30, the second cutter 70, and the positioning member 50 can move along the third direction Z as needed, all three can be mounted on the drive member 80. The drive member 80 is positioned above and connected to the support member 10. A lifting structure is provided between the drive member 80 and the support member 10, allowing the drive member 80 to drive the first cutter 30, the second cutter 70, and the positioning member 50 to move up and down. Alternatively, lifting structures can be provided at the connection points between the drive member 80 and the first cutter 30, the second cutter 70, and the positioning member 50, respectively, thereby controlling the raising and lowering of the first cutter 30, the second cutter 70, and the positioning member 50, facilitating the positioning and cutting of multiple terminals 20.

[0032] Please see Figure 2 In conjunction with the above embodiments, in some embodiments, the number of first cutting blades 30 and the number of second cutting blades 70 are both multiple, the multiple first cutting blades 30 are arranged at intervals along the first direction X, and the multiple second cutting blades 70 are arranged at intervals along the first direction X.

[0033] Understandably, the number of first cutting blades 30 and second cutting blades 70 can be set according to the number of terminals 20. When multiple first cutting blades 30 are provided, they are arranged at intervals along the first direction X, which is the same as the arrangement direction of the multiple terminals 20. When the first cutting blades 30 cut the terminals 20, the terminals 20 can be embedded between two adjacent first cutting blades 30, which facilitates the cutting of multiple first connecting parts 40. The arrangement direction of the multiple second cutting blades 70 is also the same as the arrangement direction of the multiple terminals 20, which facilitates the cutting of multiple second connecting parts 60.

[0034] Please see Figure 2In conjunction with the above embodiments, in some embodiments, the second cutter 70 and the first cutter 30 are offset along the second direction Y.

[0035] Understandably, since the second cutter 70 and the first cutter 30 are offset along the second direction Y, when multiple terminals 20 move along the first direction X under the action of the conveying structure, they will first move to the area below the first cutter 30 to cut the first connecting portion 40. At this time, the positioning member 50 can be used to position the multiple terminals 20, and the first cutter 30 can also guide the terminals 20 to ensure that the terminals 20 do not become skewed when cutting the first connecting portion 40, which is also beneficial to the accurate cutting of the second connecting portion 60. If the second cutter 70 is on the same side of the first cutter 30 along the second direction Y, and both cut simultaneously, it may cause the terminals 20 to become skewed, affecting the cutting of the terminals 20.

[0036] This application also provides a processing system including the terminal cutting device described above, which has all the technical features and beneficial effects of the terminal cutting device, and will not be described in detail here.
