Description

Technical Field

[0001] This utility model relates to the field of automatic connector assembly technology, and in particular to a feeding mechanism for pin-shaped terminals on an automatic machine. Background Technology

[0002] In automated connector assembly equipment, terminals are typically fed automatically in roll form. A transfer mechanism pushes the terminal strip along a track, cutting each terminal off the strip and inserting it into the connector core. For pin-shaped terminals, the radial dimension is small, and the pitch on the strip is also relatively small. Conventional transfer mechanisms, when pushing the strip, cannot meet the precision requirements for accurate feeding of pin-shaped terminals under continuous high-speed operation. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a material feeding mechanism for pin-shaped terminals on an automatic machine. It can structurally limit the forward and backward displacement of the pin module and reduce the impact and wear on the transmission mechanism due to motion inertia, ensuring that it can maintain high dimensional accuracy for a long time. This, in turn, ensures that the two pins can continuously drive the material to maintain a stable and consistent feeding step and feeding rhythm.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] The automatic machine's feeding mechanism for pin-shaped terminals is located beside a winding terminal feeding line extending in the X direction. The winding terminal feeding line has slots extending in the X direction, the width of which matches the width of the flattened winding terminal. The winding terminal's tape has several positioning holes arranged at equal intervals along the X direction. The mechanism includes a translation module and a pin insertion module. The translation module has limiting components and buffer components on both sides of the pin insertion module, wherein:

[0006] The translation module is located on the Y-direction side of the slot and includes a horizontally placed support plate. The support plate has a first slide rail extending in the X-direction. A push plate is slidably mounted on the first slide rail. One X-direction end of the push plate is connected to a first driving device and can slide along the first slide rail under its drive. The first driving device is located at one X-direction end of the support plate, and a first buffer and a first limiting member are respectively provided on its two Y-direction sides. Both the first buffer and the first limiting member extend in the X-direction and one end of each extends to one X-direction side of the push plate. On the other X-direction side of the push plate, a second limiting member and a second buffer are arranged in the Y-direction. The second limiting member is located on the X-direction side of the first buffer member, and the second buffer is located on the X-direction side of the first limiting member.

[0007] The pin module is located between the push plate and the winding terminal feeding line, and includes a second driving device fixed on the push plate. The second driving device is connected to a transfer plate extending in the Z direction. The lower end of the transfer plate is provided with two pins arranged in the X direction and extending in the Z direction. The distance between the two pins is an integer multiple of the distance between the two positioning holes on the strip. The second driving device can drive the transfer plate to move the two pins synchronously in the Z direction to match and insert them into two adjacent positioning holes on the strip. The first driving device can drive the push plate to move the second driving device and the transfer plate back and forth in the X direction to move the strip on it in the slot.

[0008] As a further explanation of the above technical solution:

[0009] In the above technical solution, a horizontal guide plate is fixed above the slot on the feeding line of the coil terminal. The guide plate has an X-direction extending guide groove directly above the positioning hole on the material strip in the slot. The width of the guide groove is greater than the maximum diameter of the pin, and its length is greater than the maximum distance between four adjacent positioning holes.

[0010] In the above technical solution, the guide plate is also provided with a step distance detector on the X-direction side of the guide groove and directly above the several positioning holes. The step distance detector can simultaneously detect three consecutive positioning holes on the material strip.

[0011] In the above technical solution, the guide plate is provided with a clearance groove at the lower end of the step detector, and the X-direction length of the clearance groove is greater than the farthest distance of the three consecutive positioning holes.

[0012] In the above technical solution, the support plate is provided with two first slides, each of which is provided with a first slide plate, and the two first slide plates are detachably fixed to the push plate; the first drive device is located in the middle of the two first slides and is fixed to the support plate.

[0013] In the above technical solution, the support plate is also provided with limiting plates on both sides of the push plate in the X direction, and the first limiting member, the first buffer member, the second limiting member and the second buffer member are all mounted on the limiting plate.

[0014] In the above technical solution, both the first buffer and the second buffer include an X-direction extending and adjustablely fixed to the limiting plate. Each of the mounting rods is located directly above the first slide and has an elastic element at its end facing the push plate.

[0015] In the above technical solution, both the first limiting member and the second limiting member include a limiting rod extending in the X direction and adjustablely fixed on the limiting plate, and one end of each limiting rod extends to the side of the push plate.

[0016] In the above technical solution, the pusher plate is provided with a mounting plate extending in the Z direction at the end of the feed line of the roll terminal. The second driving device is provided on one Y-direction sidewall of the mounting plate. The second driving device is connected to the second sliding plate. The second sliding plate has a shaped structure. Its horizontal arm is located above the feed line of the roll terminal and is connected to the second driving device. Its vertical arm extends to the Y-direction side of the second driving device, and the transfer plate is provided on its Y-direction sidewall.

[0017] In the above technical solution, the second drive device is further provided with a second slide rail extending in the Z direction, and the transfer plate is matched and slidably connected to the second slide rail.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting limiting parts and buffer parts on both sides of the push plate that pushes the pin module to move horizontally, the forward and backward displacement of the push plate can be further restricted structurally, and the impact and wear on the transmission mechanism due to motion inertia can be reduced, ensuring that it can maintain high dimensional accuracy for a long time, thereby ensuring that the two pins can continuously drive the material belt to maintain a stable and consistent feeding pitch and feeding rhythm; by setting a pitch detector, the pitch during the material belt feeding process can be detected in real time, and timely alarm and suspension of feeding can be given when the pitch is abnormal, so as to avoid poor assembly in subsequent stations.

[0026] like Figure 1 As shown, the feeding mechanism for the pin-shaped terminal on the automatic machine is located beside the feeding line 10 of the winding terminal extending in the X direction. The feeding line 10 of the winding terminal has a slot 11 extending in the X direction. The width of the slot 11 is adapted to the width of the winding terminal after it is flattened. The material strip 20 of the winding terminal has several positioning holes 21 arranged at equal intervals along the X direction. The feeding mechanism includes a translation module 30 and a pin insertion module 40. The translation module 30 has a limiting member and a buffer member on both sides of the pin insertion module 40.

[0027] like Figure 2 As shown, a horizontal guide plate 12 is fixed above the slot 11 on the feed line 10 of the coil terminal. The guide plate 12 has an X-direction extending guide groove 13 directly above the positioning hole 21 on the material strip 20 in the slot 11. The width of the guide groove 13 is greater than the maximum diameter of the pin 43, and its length is greater than the maximum distance between four adjacent positioning holes 21. The guide plate 12 also has a step distance detector 50 on the X-direction side of the guide groove 13 and directly above several positioning holes 21. The step distance detector 50 can simultaneously detect three consecutive positioning holes 21 on the material strip 20. The guide plate 12 has an avoidance groove 14 at the lower end of the step distance detector 50. The X-direction length of the avoidance groove 14 is greater than the farthest distance of the three consecutive positioning holes 21. In this embodiment, the step distance detector 50 is equipped with three infrared detectors arranged in the X direction. The sensing blocks are located above and below the material belt 20. When the material belt 20 is fed with a normal step distance, the positioning hole 21 on it will not block the infrared light when it reaches the position. Otherwise, it indicates that the feeding step distance of the material belt 20 is abnormal. At this time, the step distance detector 50 will issue an alarm signal and instruct the translation module 30 to stop its operation so that the operator can adjust the machine.

[0028] like Figure 3 As shown, the translation module 30 is located on the Y-direction side of the slot 11, including a horizontally placed support plate 31. The support plate 31 is provided with a first slide rail 32 extending in the X-direction. A push plate 33 is slidably mounted on the first slide rail 32. One X-direction end of the push plate 33 is connected to the first driving device 34 and can slide along the first slide rail 32 under its drive. The first driving device 34 is located at one X-direction end of the support plate 31, and a first buffer member 35 and a first limiting member 36 are respectively provided on both sides of it in the Y-direction. Both the first buffer member 35 and the first limiting member 36 extend in the X-direction and one end of each extends to one X-direction side of the push plate 33. On the other X-direction side of the push plate 33, a second limiting member 37 and a second buffer member 38 arranged in the Y-direction are provided. The second limiting member 37 is located on the X-direction side of the first buffer member 35, and the second buffer member 38 is located on the X-direction side of the first limiting member 36. In this embodiment, the support plate 31 is provided with two first slide rails 32, each of which is provided with a first slide plate 39. The two first slide plates 39 are detachably fixed to the push plate 33. The first drive device 34 is located in the middle of the two first slide rails 32 and is fixed to the support plate 31. The support plate 31 is also provided with limiting plates 1 on both sides of the push plate 33 in the X direction. The first limiting member 36, the first buffer member 35, the second limiting member 37, and the second buffer member 38 are all mounted on the limiting plate 1. The first buffer member 35 and the second buffer member 38 both include mounting rods 2 that extend in the X direction and are adjustablely fixed to the limiting plate 1. Each mounting rod 2 is located directly above a first slide rail 32 and has an elastic member 3 at its end facing the push plate 33. The first limiting member 36 and the second limiting member 37 both include limiting rods 4 that extend in the X direction and are adjustablely fixed to the limiting plate 1. The end of each limiting rod 4 extends to the side of the push plate 33.

[0029] Understandably, the first limiting member 36 and the second limiting member 37 on both sides of the push plate 33 can further restrict the forward and backward displacement of the push plate 33 structurally. The first buffer member 35 and the second buffer member 38 on both sides can reduce the impact and wear on the push plate 33 due to motion inertia, ensuring that it can maintain high dimensional accuracy for a long time, thereby ensuring that the two pins 43 can continuously drive the material belt 20 to maintain a stable and consistent feeding step and feeding rhythm.

[0030] like Figure 4 As shown, the pin module 40 is located between the push plate and the feed line 10 of the roll terminal, including a second drive device 41 fixed on the push plate 33. The second drive device 41 is connected to the transfer plate 42 extending in the Z direction. The lower end of the transfer plate 42 is provided with two pins 43 arranged in the X direction and extending in the Z direction. The distance between the two pins 43 is an integer multiple of the distance between the two positioning holes 21 on the strip 20. The second drive device 41 can drive the transfer plate 42 to move the two pins 43 synchronously in the Z direction to match and insert them into the two adjacent positioning holes 21 on the strip 20. The first drive device 34 can drive the push plate 33 to move the second drive device 41 and the transfer plate 42 back and forth in the X direction to move the strip 20 on it in the slot 11. In this embodiment, the push plate 33 is provided with a Z-direction extending mounting plate 44 at the end facing the winding terminal feeding line 10. The second driving device 41 is provided on one Y-direction sidewall of the mounting plate 44. The second driving device is connected to the second slide plate 45. The second slide plate 45 has an L-shaped structure. Its horizontal arm is located above the winding terminal feeding line 10 and is connected to the second driving device 41. Its vertical arm extends to the Y-direction side of the second driving device 41, and a transfer plate 42 is provided on its Y-direction sidewall. The second driving device 41 is also provided with a Z-direction extending second slide rail 46. The transfer plate 42 is matched and installed on the second slide rail 46 and slidably connected to it.

[0031] During operation, the integrated coil terminal and the strip 20 are flattened and fed into the slot 11. The second drive device 41 of the pin module 40 drives the two pins 43 to move down and insert into the two adjacent positioning holes 21 and move up. At the same time, the first drive device 34 drives the push plate 33 to move the pin module 40 forward synchronously. The two pins 43 hook the strip 20 and drive the terminal on it to move up and forward synchronously by one step. The two pins 43 move down and put down the strip 20. After completion, the two pins 43 move up and back to their original positions, thus completing the precise forward movement of the strip 20 by one step.

[0032] In this embodiment, both the first drive device 34 and the second drive device 41 are linear cylinders.

[0033] This invention further restricts the forward and backward displacement of the push plate 33 by setting limiting and buffering components on both sides of the push plate 33 that pushes the pin module 40 to move horizontally. It also reduces the impact and wear on the transmission mechanism due to motion inertia, ensuring that it can maintain high dimensional accuracy for a long time. This ensures that the two pins 43 can continuously drive the material belt 20 to maintain a stable and consistent feeding pitch and feeding rhythm. By setting a pitch detector 50, the pitch of the material belt 20 during the feeding process can be detected in real time, and timely warning and feeding can be paused when the pitch is abnormal, so as to avoid poor assembly in subsequent stations.

[0034] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
