Technical Field

[0001] The present application belongs to the technical field of electric connector production, and in particular relates to a terminal bending device. Background Art

[0002] Female header electronic connectors play an important role in connecting and transmitting signals in electronic devices. Female header electronic connectors mainly include injection-molded insulating shells and electroplated connecting terminals.

[0003] During the production process of female connectors, bending equipment is required to bend the connecting terminals. However, the following problems are common in existing bending devices: During production, bending equipment is required to complete operations such as feeding, transferring, bending the terminals, and discharging the female connectors. Generally, multiple travel mechanisms are stacked on the bending equipment to achieve the above operations, thereby increasing the equipment R&D cost or the company's procurement cost. Utility Model Content

[0004] In order to address the above-mentioned deficiencies in the prior art, the present application provides a terminal bending device, which has relatively fewer travel mechanisms and has lower production costs.

[0005] In order to achieve the above purpose, the utility model adopts the following technologies:

[0006] A terminal bending device, characterized by comprising:

[0007] The feeding mechanism includes a conveying track, at the end of which a transfer frame is provided for receiving the female terminals on the conveying track. The transfer frame is provided with an opening on one side, and the terminals of the female terminals extend out of the transfer frame. The transfer frame is movable along a conveying direction perpendicular to the conveying track.

[0008] The bending mechanism is provided on one side of the transfer frame, and includes a rotating plate arranged toward the conveying direction of the conveying track, and one end of the rotating plate is provided with a rotating shaft arranged toward the conveying direction of the conveying track;

[0009] The transmission mechanism is arranged at one end of the transfer frame and is used to drive the transfer frame and the rotating shaft. It includes an electric screw arranged perpendicular to the conveying direction of the conveying track and a gear coaxially connected to one end of the rotating shaft. The movable end of the electric screw is connected to a rack that cooperates with the gear, and the rack is movably connected to the transfer frame.

[0010] Furthermore, a pair of guide bars perpendicular to its conveying direction are provided at the end of the conveying track, the transfer frame is fitted between the two guide bars, and a limit block is provided at the end of the guide bar; one end of the transfer frame is connected to a connecting rod, the end of the connecting rod is connected to a support plate, one end of the rack is vertically provided with a vertical plate, and a guide rod arranged parallel to the rack is passed through the vertical plate, one end of the guide rod is vertically connected to the support plate, and a spring is provided on the guide rod, and the spring is connected between the support plate and the vertical plate. When the spring is in a natural state, the other end of the rack is located below the support plate, and the movable end of the electric screw is connected to one end of the rack.

[0011] Furthermore, the feeding mechanism, the bending mechanism and the transmission mechanism are all arranged on a base.

[0012] Furthermore, a discharge hole is opened on the base below the transfer frame, and the guide bars are located on both sides of the discharge hole; a strip hole is opened on the other side of the transfer frame, and a push plate adapted to the size of the strip hole is mounted on the other side of the transfer frame.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] The embodiment of the present application provides a terminal bending device, such as Figure 1 and Figure 2 As shown, it includes: a feeding mechanism 1, a bending mechanism 3 and a transmission mechanism 4.

[0025] Among them, the feeding mechanism 1 includes a conveying track 11, the front end of the conveying track 11 is used to connect the existing mother-row conveying device, which conveys the mother-row to be bent to the conveying track 11, and the end of the conveying track 11 is provided with a transfer frame 12 for receiving the mother-row 2 on the conveying track 11. One side of the transfer frame 12 is opened, and the terminal of the mother-row 2 extends out of the transfer frame 12. The transfer frame 12 is moved along the conveying direction perpendicular to the conveying track 11; the bending mechanism 3 is provided on one side of the transfer frame 12, which includes a feeding mechanism 3 for feeding the mother-row toward the conveying track 11. A rotating plate 31 is set in the conveying direction. One end of the rotating plate 31 is provided with a rotating shaft 32 set in the conveying direction of the conveying track 11, and the rotating shaft 32 is mounted on a pair of rotating seats 33; the transmission mechanism 4 is set at one end of the transfer frame 12, for driving the transfer frame 12 and the rotating shaft 32, which includes an electric screw 41 set perpendicular to the conveying direction of the conveying track 11 and a gear 42 coaxially connected to one end of the rotating shaft 32, the movable end of the electric screw 41 is connected to a rack 43 that cooperates with the gear 42, and the rack 43 is movably connected to the transfer frame 12.

[0026] When in use, the conveying track 11 successively receives a plurality of mother row mothers 2 to be processed conveyed by the mother row conveying device. Under the action of the mother row conveying device, a mother row mother 2 located at the end of the conveying track 11 is sent to the transfer frame 2; the electric screw 41 runs, driving the rack 43 to move, thereby driving the transfer frame 2 to move toward the bending mechanism 3. When the part to be bent of the terminal of the mother row mother 2 is completely moved to the surface of the rotating plate 31, the electric screw 41 will stop driving the transfer frame 2, and the position of the transfer frame 2 is fixed. The electric screw 41 continues to drive the rack 43 to move toward the rotating shaft 32 and make the rack 43 cooperate with the gear 42, thereby driving the rotating plate 31 to press the terminal to rotate around the rotating shaft 32 toward the transfer frame 12, bending the terminal of the mother row 2 upward; the electric screw 41 runs in the opposite direction to make the rotating plate 31 rotate, and the transfer frame 12 brings the processed mother row 2 back to the end of the conveying track 11 and discharges the material, and then processes the next mother row 2. The device drives both the transfer frame 12 and the rotating plate 31 through the electric screw 41, thereby realizing the basic functions of the bending device while reducing the use of the stroke mechanism, which is beneficial to reducing the production cost of the device.

[0027] In order to realize the intermittent control of the transfer frame 12 and the control of the rotating plate 31 by the electric screw 41, the present embodiment proposes a preferred solution, which is as follows: Figures 1 to 4As shown, a pair of guide bars 13 perpendicular to its conveying direction is provided at the end of the conveying track 11, and the two ends of the transfer frame 12 are fitted between the two guide bars 13, and a limit block 131 is provided at the end of the guide bar 13; one end of the transfer frame 12 is connected to a connecting rod 121, and the end of the connecting rod 121 is connected to a support plate 122, and one end of the rack 43 is vertically provided with a vertical plate 431, and a pair of guide rods 432 arranged parallel to the rack 43 are passed through the vertical plate 431, one end of the guide rod 432 is vertically connected to the support plate 122, and a spring 433 is sleeved on the guide rod 432, and the spring 433 is connected between the support plate 122 and the vertical plate 431. When the spring 433 is in a natural state, the other end of the rack 43 is located below the support plate 122, and the movable end of the electric screw 41 is connected to one end of the rack 43. Accordingly, the elastic coefficient of the spring 433 should be reasonably selected so that when the linear screw 41 drives the rack 43 to move, the spring 433 can support the support plate 122 to move along with the rack 43. When in use, the electric screw 41 drives the rack 43 to move. Under the action of the spring 433, the connecting rod 121 and the support plate 122, the transfer frame 12 will move along with the rack 43 until the transfer frame 12 moves along the guide bar 13 and abuts against the limit block 131. The electric screw 41 drives the rack 43 to continue moving, thereby driving the vertical plate 431 along the guide rod 432 to move closer to the support plate 122. The spring 433 is compressed. As the rack 43 moves, the closer the distance between the vertical plate 431 and the support plate 122 is, the greater the degree of compression of the spring 433 is. The greater the force 433 uses to press the transfer frame 12 against the limit block 131 by the connecting rod 121, the fixed position of the transfer frame 12 is achieved. The electric screw 41 drives the rack to continue to move, so that the rack 43 cooperates with the gear 42, driving the rotating plate 31 to rotate, thereby achieving the bending of the terminal; the electric screw 41 runs in the reverse direction, first disengaging the rack 43 from the gear 42, and then disengaging the transfer frame 12 from the limit block 131. The spring 433 returns to its natural state and pulls the transfer frame 12 to the end of the conveyor track 11 through the connecting rod 121. The design of the connection structure between the transfer frame 12 and the rack 43, and between the rack 43 and the movable end of the electric screw 41, realizes the intermittent control of the transfer frame 12 and the rotating plate 31 by the electric screw 41, which not only reduces the use of the stroke mechanism and reduces the manufacturing cost, but also optimizes the structure of the device and improves the degree of automation of the device.

[0028] Specifically, such as Figures 1 to 5 As shown, the feeding mechanism 1, the bending mechanism 3 and the transmission mechanism 4 are all arranged on a base 5, which improves the integration of the device and facilitates the transfer of the device.

[0029] To further reduce the use of travel mechanisms, such as Figure 2 、 Figure 3 、 Figure 5A discharge hole 51 can be opened on the base 5 below the transfer frame 12, and the guide bars 13 are respectively located on both sides of the discharge hole 51; a strip hole 123 is opened on the other side of the transfer frame 12, and a push plate 14 with a size adapted to the strip hole 123 is mounted on the other side of the transfer frame 12. After the electric screw 41 runs in the reverse direction to drive the transfer frame 12 back to the end of the conveying track 11, the electric screw 41 continues to run in the reverse direction and drives the transfer frame 12 to move. During the movement of the transfer frame 12, the push plate 14 enters the interior of the transfer frame 12 through the strip hole 123, thereby pushing out the processed row mother 2 in the transfer frame 12. The pushed out row mother 2 falls out of the discharge hole 51, thereby realizing automatic discharge of the device, eliminating the stroke mechanism for discharging the row mother 2 in the existing bending equipment, further reducing the production cost of the device, and further improving the degree of automation of the device.

[0030] During the bending process of the female connector 2 by the rotating plate 31, the female connector 2 may be displaced in the transfer frame 12, resulting in uneven quality of the bent terminals. To solve the above problem, this embodiment proposes a preferred solution, which is as follows: Figures 1 to 3 As shown, the width of the top of the transfer frame 12 is smaller than the width of its bottom. A pressure plate 6 is mounted above the bending mechanism 3, adapted to the size of the female connector 2 and movable perpendicularly to the base 5. Correspondingly, a linear mechanism 7 can be mounted on the bending mechanism 3, with its movable end perpendicularly facing the base 5 and connected to the pressure plate 6. During operation, before the rotating plate 31 rotates, the linear mechanism 7 first drives the pressure plate 6 toward the transfer frame 12 until the pressure plate 6 presses the female connector 2 shell exposed at the top of the transfer frame 12. This ensures that the female connector 2 will not be displaced when the rotating plate 31 bends the terminal, thereby ensuring that the terminal bent by the device is flat, thereby ensuring the quality of the terminal bending.

[0031] Specifically, such as Figure 3 As shown, the rotating plate 31 is provided with limiting grooves 311 along its length direction, which are adapted to the terminals of the female connector 2. The setting of the limiting grooves 311 can further standardize the bending shape of the terminals and improve the quality of the terminal bending.

[0032] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application.
