Description

Technical Field

[0001] The present application relates to the field of connector production equipment, and in particular to a connector pin bending device. Background Art

[0002] A connector is a component used to transmit power or signals between two devices. Figure 1 The connector includes a connection shell 8 and two rows of connection pins 9, and a housing groove is provided on one side of the connection shell 8. The two rows of connection pins 9 are respectively provided as first pins and second pins, and the first pins and the second pins are respectively provided in one row, wherein the first pins in one row and the second pins in the other row are distributed along the height direction of the connector housing, and the first pins are closer to the housing groove than the second pins.

[0003] In the actual production process, the first pin and the second pin arranged in a straight line need to be bent to adapt to the specific connection position. Figure 2 One end of the first pin is fixedly inserted into the connection housing 8, and the other end of the first pin is bent toward the housing groove. In addition, one end of the second pin is fixedly inserted into the connection housing 8, and the other end of the second pin is bent toward the first pin.

[0004] In the existing related technology, the bending of the first pin and the second pin is generally performed at the same time, that is, the first pin and the second pin are first plugged and fixed to the connecting shell 8, and then the first pin and the second pin are bent.

[0005] With respect to the above-mentioned related technologies, when the spacing between the first pin and the second pin is small, they are prone to interfere with each other during the bending process, making it difficult to accurately bend the first pin or the second pin to the specified specifications, and it is difficult to ensure the production quality of connectors with multiple rows of pins. Summary of the invention

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

[0007] The present application provides a connector pin bending device that adopts the following technical solution: A connector pin bending device comprises a frame and a plurality of pin bending mechanisms, wherein the plurality of pin bending mechanisms are arranged on the frame, and the plurality of pin bending mechanisms are respectively and one by one 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, wherein the first positioning component is used to fix a connector to which no connecting pins are plugged, 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 to which the connecting pins are not bent, and the pin bending component is used to bend one row of connecting pins fixed to the connecting shell.

[0008] By adopting the above technical solution, the first positioning component fixes the connector without connecting pins, and fixes a row of connecting pins to the connecting shell through the pin fixing component, thereby completing the installation of the connecting pins. Subsequently, the second positioning component fixes the connector with unbent connecting pins, and bends the newly fixed row of connecting pins through the pin bending component, thereby completing the fixing and bending of one row of connecting pins.

[0009] 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, thereby making it less likely for two adjacent rows of connecting pins to interfere with each other, and reducing 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.

[0010] 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; The fixed clamping block is installed on the clamping base, the movable clamping block is slidably matched with the clamping base, and a clamping elastic member is provided between the movable clamping block and the fixed clamping block; 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.

[0011] 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.

[0012] When the movable clamping block moves toward the fixed clamping block, the clamping elastic member is deformed, so that the movable clamping block is not easy to contact the connecting pin too quickly, which helps to reduce the wear of the connecting pin by the movable clamping block.

[0013] The clamping block driving member causes the movable clamping block to move toward or away from the fixed clamping block through the clamping driving block; The movable clamping block is provided with a passive inclined surface, and the clamping driving block is provided with an active inclined surface. When the active inclined surface of the clamping driving block moves along the passive inclined surface, the movable clamping block moves toward or away from the fixed clamping block.

[0014] By adopting the above technical solution, the passive inclined plane and the active inclined plane are used for switching, so that the fixed clamping block can be arranged in the actual installation position according to the space of the frame. In addition, according to the parameters of the clamping block driving member, the inclination angles of the passive inclined plane and the active inclined plane are adjusted to change the movement speed of the movable clamping block, thereby more finely adjusting the speed of the movable clamping block approaching the connecting pin, which is conducive to further reducing the occurrence of the connecting pin being worn by the movable clamping block.

[0015] Optionally, the first positioning assembly includes a first positioning block and a first positioning drive member, the first positioning block is provided with a shell positioning groove, the shell positioning groove is used to accommodate the connecting shell, and the first positioning drive member is used to move the shell positioning groove toward or away from the connecting shell.

[0016] By adopting the above technical solution, when the connecting pin is bent, the inner wall of the housing positioning groove limits the connector housing, thereby making the connecting housing less likely to shake, thereby ensuring that the connecting pin can be accurately aligned with the socket on the connecting housing.

[0017] Optionally, the pin bending assembly includes a rotating ring, a pin bending block and a bending block driving member, the rotating ring rotatably cooperates with the frame, 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 member is used to drive the rotating ring to rotate.

[0018] By adopting the above technical solution, the pin bending block is tightly fitted to the connecting pin, and then the pin bending block is driven to rotate by the rotation of the rotating ring, thereby bending the connecting pin. Compared with other bending methods, such as bending by linear motion, the bending stroke of the connecting pin by the revolution of the pin bending block is longer. During the bending process, the internal gravitational force of the connecting pin changes more slowly, which is conducive to reducing the occurrence of micro cracks and elastic deformation of the connecting pin.

[0019] Optionally, the bending drive member is of a cylinder type, 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.

[0020] By adopting the above technical solution, it is easy to ensure the bending strength of the pin bending block on the connecting pin.

[0021] 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 matched with the positioning base, the positioning drive block is slidably matched with the positioning base, and the angle between the sliding direction of the positioning drive block and the sliding direction of the second positioning block is an acute angle, a right angle or an obtuse angle; The positioning drive block is provided with a driving inclined groove, and the second positioning block is provided with a transmission protrusion, and the transmission protrusion slides and cooperates with the driving inclined groove. When the transmission protrusion slides along the driving inclined groove, the second positioning block slides, and the second positioning drive member is used to drive the positioning drive block to slide.

[0022] By adopting the above technical solution, when the positioning drive block passes through the driving bevel groove and the transmission protrusion, the second positioning block moves toward the direction close to the connection shell and the connection pin, so that the positioning block is tightly matched with the inner wall of the housing groove and the connection pin, so that the connector is not easy to shake during the bending process. In addition, according to the parameters of the second positioning drive member, the inclination angle of the driving bevel groove can be adjusted to change the movement speed of the second positioning block, and then the speed of the second positioning block approaching the connection pin can be more finely adjusted, which is conducive to further reducing the occurrence of the connection shell and the connection pin being worn by the second positioning block.

[0023] Optionally, the second positioning block is provided with a pin slot, and the pin slot is used for plugging in the bent connecting pin.

[0024] By adopting the above technical solution, the pin slot accommodates the connecting pin inside, so that the bent connecting pin is not easily disturbed by other connecting pins during the bending process, and the bending connecting pin is reduced. At the same time, after the connecting pin is accommodated in the pin slot, it also makes the connector less likely to shake during the bending process.

[0025] Optionally, the connector pin bending device further comprises a connector conveying mechanism, and the connector conveying mechanism comprises a linear conveying component and a top limiting component; The linear conveying assembly comprises a conveying base, a conveying straight rod, a conveying tooth block and a straight rod driving member, wherein the conveying base is mounted on a frame, and a horizontal conveying groove is provided on the conveying base, wherein the horizontal conveying groove extends in a horizontal direction, and the conveying straight rod is slidably matched with the conveying base along the extension direction of the horizontal conveying groove, and a plurality of conveying tooth blocks are provided, and the plurality of conveying tooth blocks are distributed along the length direction of the conveying straight rod; The conveying tooth block is rotatably matched with the conveying straight rod, a tooth block elastic member is provided between the conveying tooth block and the conveying straight rod, and the conveying tooth block is provided with a return inclined surface; The straight rod driving member is used to drive the conveying straight rod to slide; The top limiting assembly is used to close the top of the horizontal conveying trough.

[0026] By adopting the above technical solution, each connector is pushed to move along the horizontal conveying groove to each pin bending mechanism through the reciprocating motion of the conveying straight rod in the horizontal direction, which occupies a small space and enables the connectors to move in sequence and in an orderly manner, thereby reducing the occurrence of connector clustering that affects the fixation of the first positioning assembly and the second positioning assembly.

[0027] Optionally, the top limit assembly includes a top base and a top limit block, the top base is installed on the conveying base, and a plurality of top limit blocks are provided, and the plurality of top limit blocks are respectively arranged in one-to-one correspondence with each conveying tooth block; the top limit block slides and cooperates with the top base in the vertical direction, the top limit block is located at the top of the horizontal conveying trough, and a limit block elastic member is provided between the top limit block and the top base.

[0028] By adopting the above technical solution, when the connector moves along the horizontal conveying trough, the top limit block limits the connector from the top of the connector, making it difficult for the connector to shake or disengage significantly during the reciprocating motion of the conveying straight rod, thereby further ensuring the orderly conveying of the connector.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. The first positioning component fixes the connector without connecting pins, and fixes a row of connecting pins to the connecting housing through the pin fixing component, thereby completing the installation of the connecting pins.

[0064] Reference Figure 3 , Fig.11 , Fig.14 as well as Fig.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, which is used to plug 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 fits tightly with the connecting pin 9, so as to protect the connecting pin 9 that has been bent in the first pin bending mechanism from being affected by the connecting pin 9 that needs to be bent in the second pin bending mechanism, and the connecting pin 9 is also corrected for a second time through the pin slot 522 to ensure that the connecting pin 9 meets the design requirements.

[0065] The implementation principle of the pin bending equipment of a connector in an embodiment of the present application is as follows: after one of the pin bending mechanisms fixes and bends one row of connecting pins 9, the second pin bending mechanism fixes and bends the second row of connecting pins 9, thereby making it less likely for the two adjacent rows of connecting pins 9 to interfere with each other, thereby reducing the situation where the connecting pins 9 at the top are not bent and hinder the bending of the connecting pins 9 at the bottom, thereby ensuring that each row of connecting pins 9 can be accurately bent to the specified specifications, thereby ensuring the production quality of connectors with multiple rows of pins.

[0066] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
