Description

TECHNICAL FIELD

[0001] The present application relates to the field of connector production equipment, and particularly relates to a connector pin bending device. BACKGROUND

[0002] A connector is an element for realizing power transmission or signal transmission between two devices. Referring to Figure 1 , the connector comprises a connecting shell 8 and two rows of connecting pins 9, and the connecting shell 8 is provided with a shell groove on one side. The two rows of connecting pins 9 are respectively provided as first pins and second pins, and the first pins and the second pins are respectively arranged in one row. The first pins and the second pins in one row are distributed along the height direction of the connector shell, and the first pins are closer to the shell groove than the second pins.

[0003] In the actual production process, the above-mentioned first pins and second pins arranged in a straight line need to be bent to adapt to the specific connection position. Specifically, referring to Figure 2 , one end of the first pin is fixedly arranged in the connecting shell 8, and the other end of the first pin is arranged to be bent towards the shell groove. In addition, one end of the second pin is fixedly arranged in the connecting shell 8, and the other end of the second pin is arranged to be bent towards the first pin.

[0004] In the prior art, the bending of the first pins and the second pins is generally performed simultaneously, that is, the first pins and the second pins are first inserted and fixed in the connecting shell 8, and then the first pins and the second pins are bent.

[0005] For the related art in the above, when the distance between the first pins and the second pins is small, the first pins and the second pins are easy to interfere with each other in the bending process, so that the first pins or the second pins are difficult to be accurately bent to the specified specification, and it is difficult to ensure the production quality of the connector provided with multiple rows of pins. SUMMARY

[0006] In order to ensure the production quality of the connector provided with multiple rows of pins, the present application provides a connector pin bending device.

[0007] The connector pin bending device provided by the present application adopts the following technical scheme:

[0008] A connector pin bending device comprises a frame and a plurality of pin bending mechanisms, wherein the plurality of pin bending mechanisms are all arranged on the frame, and the plurality of pin bending mechanisms are respectively used to plug, fix and bend each row of connecting pins; the pin bending mechanism comprises a first positioning component, a pin fixing component, a second positioning component and a pin bending component, the first positioning component is used to fix a connector that is not plugged with connecting pins, the pin fixing component is used to plug and fix one row of connecting pins to a connecting shell, the second positioning component is used to fix a connector whose connecting pins are not bent, and the pin bending component is used to bend one row of connecting pins fixed to the connecting shell.

[0009] By adopting the above technical solution, the first positioning assembly fixes the connector without connecting pins, and the pin fixing assembly fixes a row of connecting pins to the connecting housing, thus completing the installation of the connecting pins. Subsequently, the second positioning assembly fixes the connector with the unbent connecting pins, and the pin bending assembly bends the newly fixed row of connecting pins, thus completing the fixing and bending of one row of connecting pins.

[0010] After one of the pin bending mechanisms fixes and bends one row of connecting pins, the remaining pin bending mechanisms fix and bend the remaining rows of connecting pins in turn, so that the two adjacent rows of connecting pins are less likely to interfere with each other, and reduce the situation where the connecting pins at the top are not bent and hinder the bending of the connecting pins at the bottom, thereby ensuring that each row of connecting pins can be accurately bent to the specified specifications, ensuring the production quality of connectors with multiple rows of pins.

[0011] Optionally, the pin fixing assembly includes a clamping base, a fixed clamping block, a movable clamping block, a clamping block driving member and a fixed driving member;

[0012] The fixed clamping block is mounted on the clamping base, the movable clamping block is slidably fitted on the clamping base, and a clamping elastic member is provided between the movable clamping block and the fixed clamping block;

[0013] The clamping block driving member is used to move the movable clamping block toward or away from the fixed clamping block, and the fixed driving member is used to move the fixed clamping block and the movable clamping block toward or away from the connection housing.

[0014] By adopting the above technical solution, the connecting pin is clamped and fixed by the movable clamping block and the fixed clamping block, and then the movable clamping block, the fixed clamping block and the connecting pin are moved toward the connecting shell by the fixed driving member, so that the pin is plugged into the connecting shell.

[0015] When the movable clamping block moves towards the fixed clamping block, the clamping elastic element is deformed, so that the movable clamping block is not easy to contact the connecting pin too fast, which is beneficial to reduce the situation that the connecting pin is worn by the movable clamping block.

[0016] The clamping block driving element drives the movable clamping block to move towards or away from the fixed clamping block through the clamping driving block;

[0017] The movable clamping block is provided with a passive slope, and the clamping driving block is provided with an active slope, when the active slope of the clamping driving block moves along the passive slope, the movable clamping block moves towards or away from the fixed clamping block.

[0018] By using the passive slope and the active slope for reversing, the fixed clamping block can be actually installed according to the space arrangement of the rack. In addition, according to the parameters of the clamping block driving element, the inclination angles of the passive slope and the active slope are adjusted to change the movement speed of the movable clamping block, and then the speed of the movable clamping block approaching the connecting pin is more finely adjusted, which is beneficial to further reduce the situation that the connecting pin is worn by the movable clamping block.

[0019] Optionally, the first positioning assembly includes a first positioning block and a first positioning driving element, the first positioning block is provided with a shell positioning groove, the shell positioning groove is used for accommodating the connecting shell, and the first positioning driving element is used for driving the shell positioning groove to move towards or away from the connecting shell.

[0020] By using the above technical scheme, when the connecting pin is bent, the inner wall of the shell positioning groove limits the connector shell, so that the connecting shell is not easy to shake, thereby ensuring that the connecting pin can accurately align with the jack on the connecting shell.

[0021] Optionally, the pin bending assembly includes a rotating ring, a pin bending block and a bending block driving element, the rotating ring is rotationally fitted in the rack, the pin bending block is installed on the rotating ring, and the pin bending block is arranged away from the axis of the rotating ring, and the bending block driving element is used to drive the rotating ring to rotate.

[0022] By using the above technical scheme, the pin bending block abuts against the connecting pin, and then the pin bending block is driven to rotate by the rotation of the rotating ring, so that the connecting pin is bent. Compared with other bending methods, such as straight line movement, the connecting pin is bent by the revolution of the pin bending block, and the stroke of the connecting pin is longer, and the internal force of the connecting pin changes relatively gently during the bending process, which is beneficial to reduce the occurrence of micro-cracks and the elastic deformation of the connecting pin.

[0023] Optionally, the bending drive member is a cylinder, one end of the bending drive member is rotationally engaged with the frame, and the other end of the bending drive member is rotationally engaged with the pin bending block.

[0024] By adopting the above technical solution, it is easy to ensure the bending strength of the pin bending block on the connecting pin.

[0025] Optionally, the second positioning assembly includes a positioning base, a second positioning block, a positioning drive block, and a second positioning drive member, the second positioning block is slidably engaged with the positioning base, the positioning drive block is slidably engaged with the positioning base, and an angle between a sliding direction of the positioning drive block and a sliding direction of the second positioning block is an acute angle, a right angle, or an obtuse angle;

[0026] The positioning drive block is provided with a driving inclined groove, and the second positioning block is provided with a transmission protrusion. The transmission protrusion slides and fits in the driving inclined groove. When the transmission protrusion slides along the driving inclined groove, the second positioning block slides and moves. The second positioning drive member is used to drive the positioning drive block to slide.

[0027] By employing this technical solution, the second positioning block moves toward the connector housing and connector pins as the positioning drive block passes through the drive chute and transmission protrusion, thereby causing the positioning block to tightly fit against the inner wall of the housing recess and the connector pins, preventing the connector from shaking during bending. Furthermore, by adjusting the angle of the drive chute based on the parameters of the second positioning drive member, the movement speed of the second positioning block can be varied, allowing for more precise adjustment of the speed at which the second positioning block approaches the connector pins, further reducing wear on the connector housing and connector pins caused by the second positioning block.

[0028] Optionally, the second positioning block is provided with a pin slot, and the pin slot is used to insert a bent connecting pin.

[0029] By adopting the above technical solution, the pin slot accommodates the connecting pin inside, making the bent connecting pin less likely to be disturbed by other connecting pins during the bending process, thereby reducing the possibility of the bent connecting pin being deflected. At the same time, the connecting pin is accommodated in the pin slot, which also makes the connector less likely to shake during the bending process.

[0030] Optionally, the connector pin bending device further includes a connector conveying mechanism, and the connector conveying mechanism includes a linear conveying component and a top limiting component;

[0031] The straight conveying assembly comprises a conveying base, a conveying straight rod, conveying tooth blocks and a straight rod driving member, the conveying base is installed on a rack, the conveying base is provided with a horizontal conveying groove extending in the horizontal direction, the conveying straight rod is slidingly fitted to the conveying base along the extension direction of the horizontal conveying groove, and the conveying tooth blocks are provided in plurality, and the plurality of conveying tooth blocks are distributed along the length direction of the conveying straight rod;

[0032] The conveying tooth blocks are rotationally fitted to the conveying straight rod, tooth block elastic members are arranged between the conveying tooth blocks and the conveying straight rod, and the conveying tooth blocks are provided with a turn-back inclined surface;

[0033] The straight rod driving member is used for driving the sliding movement of the conveying straight rod;

[0034] The top limiting assembly is used for closing the top of the horizontal conveying groove.

[0035] By adopting the above technical scheme, the connectors are sequentially and orderly moved by the reciprocating movement of the conveying straight rod in the horizontal direction to the pin-bending mechanisms, the occupied space is small, and the connectors are sequentially and orderly moved, thereby reducing the situation that the connectors are clustered to affect the fixation of the first and second positioning assemblies.

[0036] Optionally, the top limiting assembly comprises a top base and top limiting blocks, the top base is installed on the conveying base, the top limiting blocks are provided in plurality, and the plurality of top limiting blocks are respectively and correspondingly arranged with the conveying tooth blocks; the top limiting blocks are slidingly fitted to the top base in the vertical direction, the top limiting blocks are located at the top of the horizontal conveying groove, and limiting block elastic members are arranged between the top limiting blocks and the top base.

[0037] By adopting the above technical scheme, when the connectors move along the horizontal conveying groove, the top limiting blocks limit the connectors from the top of the connectors, so that the connectors are not easily shaken or separated from the reciprocating movement of the conveying straight rod, thereby further ensuring the orderly conveying of the connectors.

[0038] In summary, the present application has at least one of the following beneficial technical effects:

[0039] 1. The first positioning assembly fixes the connector without the inserted connecting pins, and fixes a row of connecting pins to the connecting shell through the pin fixing assembly, thereby completing the installation of the connecting pins.

[0075] With reference to Figure 3 , Figure 11 , Figure 14 and Figure 15 The main difference between the second pin bending mechanism and the first pin bending mechanism is that the second positioning block 52 of the second pin bending mechanism is provided with a pin slot 522 for inserting the bent connecting pin 9. When the connecting pin 9 is located in the pin slot 522, the inner wall of the pin slot 522 tightly fits the connecting pin 9, so as to protect the connecting pin 9 which has been bent in the first pin bending mechanism from being affected by the connecting pin 9 which needs to be bent in the second pin bending mechanism, and also to correct the connecting pin 9 again to ensure that the connecting pin 9 meets the design requirements.

[0076] The implementation principle of the pin bending equipment of the connector according to the embodiment of the application is that after one of the pin bending mechanisms fixes and bends one row of connecting pins 9, the second row of connecting pins 9 is fixed and bent by the second pin bending mechanism, so that the two rows of adjacent connecting pins 9 are not easy to interfere with each other, and the situation that the connecting pin 9 located at the top hinders the bending of the connecting pin 9 located at the bottom due to not being bent is reduced, thereby ensuring that each row of connecting pins 9 can be accurately bent to the specified specification, and the production quality of the connector provided with multiple rows of pins is ensured.

[0077] The above are preferred embodiments of the application, which do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape and principle of the application should be covered within the protection scope of the application.
