A terminal bending fixture

Abstract

This invention discloses a terminal bending fixture, including a base with a placement position on the base, and a flipping bending mechanism and a pressing mechanism installed corresponding to the placement position. The pressing mechanism has a plurality of partitions, the end of which is used to abut against the lower terminal. A groove is formed between two adjacent partitions, the upper end of which is used to abut against the upper terminal. The pressing mechanism limits the terminal. At the same time, the end of the partition can be used to abut against the lower row of terminals, and the upper part of the groove can be used to abut against the upper row of terminals. During the bending process, the portions of the upper and lower rows of terminals near the connector body are abutted by the pressing mechanism, while the remaining portions can be smoothly bent at 90° by the flipping bending mechanism, ensuring that the bent terminal can be perpendicular to the connector body, improving the yield rate of connector production and facilitating subsequent assembly processes.

Description

Technical Field

[0001] This invention belongs to the field of processing equipment technology, specifically a terminal bending fixture. Background Technology

[0002] Existing connectors include a housing and several terminals inserted into the housing. To facilitate installation and use, these terminals need to be bent. For example, patent document CN216488973U discloses a connector terminal bending fixture, including a base plate, a straight track on the base plate, and at least one product carrier that can move on the straight track. The base plate also has a bending assembly, which includes a first support plate and a second support plate respectively disposed on both sides of the straight track. The bending assembly also includes a bending cantilever spanning between the tops of the first and second support plates and a rotating shaft for connecting the bending cantilever to the first and second support plates. A bending knife is also provided on the bending cantilever. The bending cantilever and the bending knife are rotated together by the rotating shaft to the required bending angle to complete the bending of the connector terminal.

[0003] When implementing the above solution, the applicant found that because the terminals were not fixed, the terminals would tilt as a whole during the bending process. The connection could not be kept horizontal with the connector, and a 90° bend could not be achieved. That is, the end of the bent terminal was not vertically downward, which made it inconvenient to connect the terminal with other components. Summary of the Invention

[0004] The purpose of this invention is to provide a terminal bending fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A terminal bending fixture includes a base, on which a placement position is provided, and a flipping bending mechanism and a pressing mechanism are installed corresponding to the placement position. The pressing mechanism is provided with a plurality of partitions, the end of which is used to abut against a lower terminal. A groove is formed between two adjacent partitions, and the upper end of the groove is used to abut against an upper terminal.

[0007] In a further technical solution, the lengths of the various spacers are all different.

[0008] In a further technical solution, the depths of several of the aforementioned slots are different.

[0009] A further technical solution is provided, wherein the top pressing mechanism includes a vertical plate on the base, a top pressing cylinder is installed on the vertical plate, the output end of the top pressing cylinder is connected to a top pressing part, the top pressing part is slidably connected to the vertical plate, and the end of the top pressing part near the placement position is provided with a number of partition columns and a number of slots.

[0010] In a further technical solution, the flipping and bending mechanism includes a pushing component, which is connected to a flipping component. The pushing component drives the flipping component to rotate. The flipping component is provided with a plurality of grooves one and two that are adapted to the terminals.

[0011] In a further technical solution, the pushing component includes a pushing cylinder mounted on a base, the output end of the pushing cylinder is connected to a rack, the rack meshes with a gear, and the gear is connected to the pushing component.

[0012] In a further technical solution, the flipping assembly includes a bending arm, which is rotatably connected to the base via a rotating shaft, and one end of the rotating shaft is connected to a gear.

[0013] In a further technical solution, a pushing mechanism is also installed on the base. The pushing mechanism includes a push-pull cylinder. The output end of the push-pull cylinder is connected to a pushing seat. The pushing seat is slidably connected to the base. The placement position is located on the pushing seat.

[0014] In a further technical solution, the pusher seat is provided with a plurality of partition columns 2, which can enter the slot 1, and a slot 2 is formed between adjacent partition columns 2, and the partition column 1 can enter the slot 2.

[0015] The beneficial effects of this invention are:

[0016] The terminals are limited by the pressing mechanism. At the same time, one end of the partition can be used to hold the lower row of terminals, and the upper part of the slot can be used to hold the upper row of terminals. During the bending process, the upper and lower rows of terminals will bend upward as a whole under the force. However, the parts of the upper and lower rows of terminals near the connector body are held in place by the pressing mechanism. Therefore, the parts of the upper and lower rows of terminals near the connector body can maintain their initial state, while the rest can be smoothly bent at 90° by the flipping and bending mechanism. This ensures that the bent terminals can be perpendicular to the connector body, improves the yield rate of connector production, and facilitates the assembly of subsequent processes.

[0017] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0027] Please refer to Figures 1-3 ;

[0028] The terminal bending fixture of the present invention can bend multiple rows of terminals simultaneously and ensure that the bent parts of the multiple rows of terminals are vertically downward, that is, the bent parts are perpendicular to the connector body, which facilitates subsequent installation; specifically, it includes a base 1, on which a placement position 3 is provided, and a flipping bending mechanism 2 and a pressing mechanism 4 are installed on the base 1 corresponding to the placement position 3.

[0029] For ease of explanation, this embodiment uses a connector with two rows of staggered terminals for illustration.

[0030] Before processing, the connector has two rows of terminals extending straight out of the connector body, and these two rows of terminals are parallel. During operation, the connector body is placed on placement position 3, the shape of which is adapted to the shape of the connector to prevent it from wobbling during processing. The two rows of terminals extend out of placement position 3, and then the pressing mechanism 4 moves downwards, referring to... Figure 6The end of the spacer 44 abuts against the lower row of terminals near the connector body, or there is a small gap between the end of the spacer 44 and the lower row of terminals near the connector body. Similarly, when the pressing mechanism 4 moves downward, the upper row of terminals near the connector body can enter the slot 45, and the upper end of the slot 45 abuts against the upper row of terminals, or there is a small gap between the upper end of the slot 45 and the upper row of terminals. The pressing mechanism 4 limits the upper row of terminals and the lower row of terminals.

[0031] Then, the flipping and bending mechanism 2 is activated to bend the upper and lower rows of terminals that are not limited by the pressing mechanism 4. During the bending process, the upper and lower rows of terminals will bend upward as a whole under force. However, the parts of the upper and lower rows of terminals that are close to the connector body are held in place by the pressing mechanism 4. Therefore, the parts of the upper and lower rows of terminals that are close to the connector body can maintain their initial state, while the rest can be smoothly bent at 90° by the flipping and bending mechanism 2. This ensures that the bent terminals can be perpendicular to the connector body, improves the yield rate of connector production, and facilitates the assembly of subsequent processes.

[0032] To further explain, when the part of the terminal that is not supported is bent, for example, it is subjected to a counterclockwise force. Although the part of the terminal near the connector body is limited by the pressing mechanism 4, it will form a fulcrum. Therefore, the connector body will also be subjected to a counterclockwise force. Combined with the shape of the placement position 3, the connector body is fixed.

[0033] Based on the above processing method, the top pressing mechanism 4 can be modified to bend irregularly distributed terminals. Several irregularly distributed terminals can be divided into two parts, namely the lower part of the terminals and the upper part of the terminals.

[0034] For example, the lower part of the terminals is distributed with one high and one low (forming multiple rows), refer to Figure 7 Therefore, the length of the partition post 44 can also be distributed with one high and one low to adapt to the distribution of the lower part of the terminals. Similarly, the depth distribution of the slot 45 can also be adjusted according to the distribution of the upper part of the terminals, thereby realizing the bending operation of irregularly distributed terminals and expanding the applicability of the present invention.

[0035] The bending fixture described in this invention is not limited to bending two rows of terminals simultaneously. According to the above embodiments, it can also be used to bend multiple rows or irregularly distributed terminals.

[0036] The following describes the implementation method of the top pressure mechanism 4, referring to... Figure 3 ;

[0037] Specifically, it includes a vertical plate 41 on the base 1, and a top pressing part 43 is slidably connected to the vertical plate 41. A partition column 44 and several slots 45 are located at one end of the top pressing part 43 near the placement position 3. When in operation, the top pressing part 43 is pushed up and down relative to the vertical plate 41 by the top pressing cylinder 42. The structure is simple and practical.

[0038] The following describes the implementation method of the turning and bending mechanism 2, referring to... Figure 4 ;

[0039] Specifically, it includes a push assembly 21 and a flip assembly 22 connected by a transmission. The push assembly 21 drives the flip assembly 22 to rotate. In order to avoid the terminals shifting to the left or right during bending, the terminals need to be limited before bending. For the lower row of terminals and the upper row of terminals, there are staggered grooves 223 and 224 respectively formed on the flip assembly 22. The grooves 223 and 224 are on the same plane. Before the flip assembly 22 is activated, the plane with the grooves 223 and 224 is in a flat state. When the connector body is placed in the placement position 3, the lower row of terminals can enter the groove 223. Then the push assembly 21 drives the flip assembly 22 to rotate, which will first bend the lower row of terminals.

[0040] After bending to a certain angle, the end of the upper row of terminals will abut against the second groove 224. With the force applied by the flipping component 22, the upper row of terminals begins to bend and gradually slides into the extension direction of the second groove 224. At the same time, the second groove 224 limits the upper row of terminals. According to the above embodiment, the upper row of terminals and the lower row of terminals can be limited, thereby avoiding the terminals from shifting during bending and improving the yield.

[0041] Furthermore, the pushing component 21 includes a pushing cylinder 211 mounted on the base 1. The output end of the pushing cylinder 211 is connected to a rack 212, which meshes with a gear 213. The gear 213 is connected to the pushing component 21 and drives the rack 212 to move laterally through the pushing cylinder 211, thereby driving the gear 213 to rotate. The gear 213 drives the flipping component 22 to rotate. The flipping component 22 includes a bending arm 221, which is rotatably connected to the base 1 through a rotating shaft 222. One end of the rotating shaft 222 is connected to the gear 213. The aforementioned groove 1 223 and groove 224 are located near the placement position 3 of the bending arm 221.

[0042] In this embodiment, refer to Figure 4To facilitate material loading, a pushing mechanism 5 is also installed on the base 1. The pushing mechanism 5 includes a pushing seat 52 and a push-pull cylinder 51 connected by a transmission. The pushing seat 52 is slidably connected to the base plate, and the placement position 3 is located on the pushing seat 52. Before loading, the pushing seat 52 is in a position away from the bending arm 221. At this time, the space is relatively open, which makes it easy to put the connector body into the placement position 3. Then, the pushing seat 52 is pulled by the push-pull cylinder 51, so that the pushing seat 52 moves closer to the bending arm 221, and the lower row of terminals can be inserted into the slot 223. Then, the bending step is performed according to the above embodiment. After completion, the bending mechanism 2 is reset, and the push-pull cylinder 51 pushes the pushing seat away from the bending arm 221.

[0043] Furthermore, referring to Figure 2 and Figure 5 The push-pull base is provided with a slot 54 adapted to the first partition 44 and a second partition 53 adapted to the first partition 45. The first partition 44 and the second partition 54, as well as the first partition 45 and the second partition 53, further limit the terminal, which facilitates bending and avoids deviation from affecting the yield.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
