Description

Technical Field

[0001] This utility model relates to the field of wire processing equipment technology, and in particular to a novel terminal crimping device. Background Technology

[0002] Chinese Utility Model Patent No. ZL202222953674.6, entitled "An Improved Automatic Terminal Crimping Machine," discloses the following technical solution: An improved automatic terminal crimping machine includes a base, on which a feeding device and a crimping device are mounted. The feeding device includes a feeding seat and a conveying component. A material rail for passing terminal strips is provided inside the feeding seat. The conveying component is positioned above the material rail and fixed to a rear support. The crimping device includes a support component (lower crimping die) mounted on the base and a crimping component (upper crimping die) mounted on the rear support, with the crimping component located above the support component. The crimping component includes a pressing block, a conductor crimping component, and an insulator crimping component. The component is installed in the first limiting groove of the pressing block; the conveying component includes a column, a connecting block, a lever, a roller, and a guide block. The column is connected to a roller shaft, which is installed in the rear support. The column rotates with the roller shaft. A roller is installed on the upper end of the column near the pressing component. A guide block is installed on the side of the pressing block near the roller. The side of the guide block near the roller is set as an inclined surface. A connecting block is embedded at the lower end of the column. The column and the connecting block are rotatably connected by a pin. A lever is connected to the front end of the connecting block. The lever has an L-shaped structure. A contoured surface is set on the end of the lever near the material rail. The contoured surface can be pressed into the belt hole of the terminal material strip, driving the material strip to move forward with the conveying component. A spring is connected on the side of the column away from the pressing component. The other end of the spring is connected to a guide rod extending from the rear support.

[0003] During the operation of the aforementioned improved automatic terminal crimping machine, when the support component and the crimping component close and crimp the terminals, the spring pulls the lower end of the column to swing away from the crimping device and causes the pusher block to move into the next hole of the terminal strip. When the crimping component moves upward and retracts from the support component, the pressure block drives the guide block to move upward and the inclined surface of the guide block pushes the roller and the upper end of the column away from the crimping device, thereby causing the lower end of the column to swing towards the crimping device, so that the pusher block pushes the terminal strip towards the crimping device and moves the terminals on the terminal strip to the crimping device position.

[0004] It should be noted that the above-mentioned improved automatic terminal crimping machine still has the following defects: the movement stroke of the pusher is determined by the guide block. For different terminal strips with different hole spacing, the improved automatic terminal crimping machine cannot make adaptive adjustments to make the movement stroke of the pusher consistent with the hole spacing of the terminal strip. That is, it has the defects of poor adjustability and poor adaptability. Utility Model Content

Detailed Implementation

[0020] The present invention will now be described in conjunction with specific embodiments.

[0021] Example 1, as Figure 1 and Figure 2 As shown, a novel terminal crimping device includes a lower seat 1 and an upper seat 2 connected to the lower seat 1 and extending to the upper side of the lower seat 1. The lower seat 1 is equipped with a strip guide 3 and a crimping lower die 4 arranged sequentially from front to back along the terminal strip conveying direction. The strip guide 3 has a strip guide channel 31 for the terminal strip to pass through.

[0022] Among them, such as Figures 1 to 3 As shown, the upper seat 2 is equipped with a material conveying assembly 5 located above the material guide 3 and a pressing upper die 6 located directly above the pressing lower die 4. The pressing upper die 6 is slidably mounted on the upper seat 2.

[0023] Specifically, such as Figures 1 to 3 As shown, the material conveying assembly 5 includes a feeding claw 51, and the rear end of the feeding claw 51 is provided with a downwardly extending tape hole insertion part 511 that mates with the tape hole of the terminal material strip.

[0024] Furthermore, such as Figures 1 to 3 As shown, the conveyor belt assembly 5 also includes a conveying drive cylinder 521 that is fastened to the upper seat 2 and moves horizontally back and forth. The conveying drive cylinder 521 is an adjustable stroke cylinder, and a translational movable block 53 is connected to the outer end of the piston rod of the conveying drive cylinder 521. It should be explained that, in order to ensure that the translational movable block 53 can move accurately back and forth, the following guide structure design can be adopted in this embodiment: Specifically, a guide rail slider pair 510 is installed between the translational movable block 53 and the upper seat 2.

[0025] Furthermore, such as Figures 1 to 3As shown, the translational movable block 53 is equipped with an adjusting block 54, and the feeding claw 51 is installed on the adjusting block 54. The lower end of the translational movable block 53 is provided with a movable block positioning groove 531 extending horizontally in the left and right direction. The adjusting block 54 is provided with a positioning part 541 embedded and positioned in the movable block positioning groove 531. The positioning part 541 of the adjusting block 54 is provided with an adjusting elongated hole 542 extending in the left and right direction. The adjusting block 54 is equipped with a locking screw 55, which passes through the adjusting elongated hole 542 of the adjusting block 54 and is screwed to the translational movable block 53.

[0026] It should be noted that the upper crimping die 6 and the lower crimping die 4 in this embodiment constitute a terminal crimping device. During operation, the upper crimping die 6 and the lower crimping die 4 cooperate to complete the terminal crimping operation. The upper crimping die 6 and the lower crimping die 4 are already existing technologies and will not be described in detail here.

[0027] In this embodiment, when the tape conveying assembly 5 and the tape guide 3 cooperate to sequentially convey the terminals to the crimping operation position, the terminal tape passes through the tape guide channel 31 of the tape guide 3, which is used to guide the terminal tape. When the material conveyor assembly 5 operates and sequentially conveys the terminals to the crimping operation, the insertion part 511 of the feeding claw 51 is first inserted into the hole of the terminal material strip. Then, the conveyor drive cylinder 521 operates and pushes the translation block 53 backward. The translation block 53 drives the adjusting block 54 and the feeding claw 51 to move backward synchronously, thereby causing the material strip to move backward one position along the material strip guide channel 31 so that the terminals on the terminal material strip are fed into the crimping operation position. After the terminals are conveyed to the position, the conveyor drive cylinder 521 resets and causes the translation block 53, the adjusting block 54, and the feeding claw 51 to move forward so that the insertion part 511 of the feeding claw 51 is inserted into the hole of the terminal material strip at the next position. The conveyor drive cylinder 521 operates in the above manner so that the terminals on the terminal material strip are sequentially conveyed to the crimping operation position.

[0028] It should be emphasized that the conveying drive cylinder 521 in this embodiment is an adjustable stroke cylinder. That is, the conveying drive cylinder 521 in this embodiment can adaptively adjust its stroke according to different terminal strips with different hole spacings, thereby adjusting the forward and backward movement strokes of the translation block 53, the adjusting block 54, and the feeding claw 51. On the one hand, it can ensure that the feeding claw 51 can accurately align with the hole of the terminal strip during feeding, and on the other hand, it can be applied to terminal strips with different hole spacings. Therefore, the strip conveying assembly 5 in this embodiment can be applied to terminal strips with different hole spacings, and has good adjustability and strong adaptability.

[0029] It should be further noted that in this embodiment, the feeding claw 51 is hinged to the adjusting block 54 via a pivot 56. The adjusting block 54 can be adjusted left and right to make the feeding claw 51 suitable for different terminal strips and to achieve accurate alignment of the strip holes. During the adjustment of the left and right position of the adjusting block 54, first loosen the locking screw 55, and then move the adjusting block 54 along the movable block positioning groove 531 of the translational movable block 53. After the adjusting block 54 is moved and adjusted to the correct position, tighten the locking screw 55 again.

[0030] In summary, the novel terminal crimping device of this embodiment has the advantages of novel structural design, strong adjustability and strong adaptability through the above structural design. Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the adjusting block 54 is provided with a pivot groove 543, the feeding claw 51 is located in the pivot groove 543 of the adjusting block 54, and the feeding claw 51 is hinged to the adjusting block 54 via a pivot 56.

[0031] The adjusting block 54 is screwed with an adjusting screw 57 extending horizontally in the left-right direction on the side of the pivot groove 543, and the adjusting screw 57 abuts against the translational movable block 53.

[0032] During the process of adjusting the left and right position of the adjusting block 54, the adjusting screw 57 can make fine adjustments to the left and right position of the adjusting block 54 to ensure the accuracy and convenience of adjusting the position of the adjusting block 54. Example 3, as Figures 1 to 3 As shown, the difference between this embodiment 3 and embodiment 1 is that a tension spring 58 is installed between the translational movable block 53 and the feeding claw 51. The lower end of the tension spring 58 is connected to the front end of the feeding claw 51, and the upper end of the tension spring 58 is connected to the translational movable block 53.

[0033] For the tension spring 58 in this embodiment, it can keep the rear end of the feeding claw 51 in abutting contact with the terminal strip; when the conveying drive cylinder 521 drives the feeding claw 51 to move backward, the tension spring 58 can keep the hole insertion part 511 of the feeding claw 51 stably in the hole, so as to prevent the hole insertion part 511 from exiting the hole when the terminal strip is pushed to move, thereby improving the stability and reliability of the terminal bolt conveying.

[0034] Example 4, as Figures 1 to 3 As shown, the difference between this embodiment four and embodiment one is that the upper seat 2 is screwed onto the inherent cylinder mounting seat 522 corresponding to the conveying drive cylinder, and the conveying drive cylinder 521 is fastened to the cylinder mounting seat 522.

[0035] The cylinder mounting base 522 is screwed with a front limit rod 591 located at the front end of the translational movable block 53. When the translational movable block 53 moves forward to the limit position, the translational movable block 53 abuts against the front limit rod 591.

[0036] In addition, the translational movable block 53 is screwed with a rear limit rod 592 that protrudes and extends to the rear end side of the translational movable block 53. When the translational movable block 53 moves backward to the limit position, the rear limit rod 592 abuts against the upper seat 2.

[0037] When the conveying drive cylinder 521 is adaptively adjusted in terms of stroke, the operator needs to adaptively adjust the positions of the front limit rod 591 and the rear limit rod 592 to ensure the accuracy of the extreme position of the translational movable block 53 and improve the stability and reliability of the terminal strip conveying operation. Example 5, such as Figure 4 As shown, the difference between this fifth embodiment and the first embodiment is that the upper pressing mold 6 includes a pressing member 61, and a pressing cutter head 611 is provided at the upper end and the lower end of the pressing member 61 respectively. The two pressing cutter heads 611 are arranged in a centrally symmetrical manner.

[0038] It should be explained that the crimping member 61 in this embodiment has two crimping heads 611. When one of the crimping heads 611 is worn, the operator only needs to rotate the crimping member 61 180 degrees to replace the crimping head 611. This can effectively increase the service life of the crimping member 61 and reduce the replacement and maintenance costs.

[0039] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
