[0001] The present application relates to the technical field of terminal production equipment, and in particular to a pin insertion machine. Background Art

[0002] Terminal blocks are a type of metal material used in connectors to conduct electrical signals, so they are widely used in electrical equipment. In the initial production process, the installation of pins on terminal blocks was done manually, and the manually assembled terminal blocks had problems such as low work efficiency and high labor costs.

[0003] In order to solve the above technical problems, the Chinese utility model patent document with the authorization announcement number CN201541044U discloses an automatic pin insertion machine for terminal blocks, which is mainly composed of a frame, a terminal block housing feeding tray, a pin feeding tray, a terminal block housing feeding device, a pin feeding device and a forming device. The pin insertion machine uses mechanical automatic pin insertion to improve work efficiency and reduce costs.

[0004] In this technical solution, the finished terminal slides out of the feeding chute. In the workshop, a receiving frame is usually placed under the feeding chute, and the terminal falls into the receiving frame for collection. When the terminal falls into the receiving frame, the pin parts may be stuck together, which may easily cause scratches or bends to the terminal during subsequent material removal. Summary of the invention

[0005] In order to better collect the wiring terminals, the present application provides a pin insertion machine.

[0006] This application adopts the following technical solutions: A pin insertion machine, comprising a pin insertion device and a receiving device arranged at the discharge position of the pin insertion device; the receiving device comprises a conveyor belt assembly, and a receiving platform and a collecting platform arranged above the conveyor belt assembly, a pushing assembly is arranged on the receiving platform, the terminals of the pin insertion device slide from the discharge position to the receiving platform, and a baffle extending upward is arranged on the side of the receiving platform away from the pin insertion device, the pushing assembly is used to push the terminals on the receiving platform one by one to the collecting platform, the collecting platform is movably arranged on the conveyor belt assembly up and down, and is used to transfer multiple terminals to the conveyor belt assembly; There are two positioning columns slidably connected to the material receiving platform assembly, and the material receiving platform is provided with a clearance groove for the positioning columns to slide. The space between the positioning columns and the pushing assembly corresponds to the discharge position of the pin device. When the pushing assembly pushes the terminal to abut against the positioning columns, the pushing assembly can synchronously push the positioning columns to slide in the direction close to the material collection platform; the positioning columns and the material receiving platform are linked to each other. When the pushing assembly pushes the positioning columns to slide in the direction close to the material collection platform, the positioning columns can be rotated into the clearance groove in the direction away from the pushing assembly. A reset component is provided on the lower surface of the material receiving platform. When the positioning column slides due to the action of the pushing assembly, the reset component is compressed and provides a force to reset the positioning column.

[0007] By adopting the above technical solution, the terminal slides from the discharge position of the pin device and slides onto the receiving table. The pushing assembly pushes the terminal to slide. When the terminal abuts against the two positioning posts, the terminal is adjusted to a flush state. The pushing assembly continues to push, which enables the positioning posts to slide and rotate synchronously to be stored in the makeshift groove, so that the terminal can be smoothly pushed onto the collecting table, and the positioning posts move away from the pushing assembly to be stored in the makeshift groove, so that the positioning posts will not generate force on the terminal when moving, thereby reducing scratches or causing the terminal to be misaligned.

[0008] Optionally, a sliding seat is slidably provided on the lower surface of the material receiving platform, a rotating column is rotatably provided in the sliding seat, the lower end of the positioning column is connected to the side wall of the rotating column, and the side wall of the sliding seat is provided with a groove for the movement of the positioning column, the pushing assembly pushes the sliding seat to slide to drive the positioning column to move, a rack is provided on the lower surface of the material receiving platform, one end of the rotating column passes through the end surface of the sliding seat and is provided with a gear, and when the pushing assembly pushes the sliding seat to slide, the gear can engage with the rack.

[0009] By adopting the above technical solution, when the pusher assembly pushes the sliding seat to slide, the gear and the rack are meshed, so that the rotating column can be rotated to drive the positioning column to enter the clearance groove.

[0010] Optionally, a waist-shaped groove is provided in the sliding seat, and the rotating column can move up and down in the waist-shaped groove. A first pushing member is provided on the upper surface of the sliding seat, and a second pushing member is provided on the lower surface of the sliding seat. The second pushing member drives the rotating column to press against the top surface of the waist-shaped groove to limit the rotation of the rotating column; a resistance bar is provided on the lower surface of the material receiving platform. When the pushing assembly drives the sliding seat to slide, the first pushing member can drive the rotating column to move downward so that the gear and the rack are meshed.

[0011] By adopting the above technical solution, before the terminal abuts against the two positioning posts, the positioning posts are not easy to rotate, so that the two positioning posts can make the terminals flush, which is conducive to the subsequent pushing assembly to push the terminals neatly onto the collection table.

[0012] Optionally, the first pushing member includes a first pushing rod slidably arranged on the upper surface of the sliding seat, and a first elastic member arranged on the outer wall of the first pushing rod. The outer wall of the rotating column is provided with an annular groove, and the end of the first pushing rod abuts against the annular groove. The end of the abutment strip is inclined with an abutment surface. When the sliding seat moves, the upper end of the first pushing rod is pressed by the abutment surface and moves downward, and at this time the first elastic member is compressed.

[0013] By adopting the above technical solution, the first push rod extends in the annular groove, and when the first push rod moves downward, it can drive the rotating rod to move downward, so that the gear can mesh with the rack.

[0014] Optionally, the second pushing member includes a second pushing rod slidably penetrated through the lower surface of the sliding seat and a second elastic member arranged on the outer wall of the second pushing rod, the end of the second pushing rod extends into the annular groove, and the second elastic member can provide a force to drive the rotating rod to abut against the top surface of the waist-shaped groove.

[0015] By adopting the above technical solution, the second elastic member drives the second push rod to move upward, thereby pushing the rotating rod upward to press against the top surface of the waist-shaped groove.

[0016] Optionally, the inner top surface of the waist-shaped groove is set to a rough structure.

[0017] By adopting the above technical solution, the rotating rod is not easy to rotate, so the terminal can be stably adjusted to a flush state.

[0018] Optionally, a reversing groove is provided on the upper surface of the material receiving platform, the length of the reversing groove is greater than the length of the terminal, and the depth of the reversing groove gradually becomes shallower towards the direction approaching the material collecting platform.

[0019] By adopting the above technical solution, when the terminal slides out from the pin device, the pin of the terminal is horizontally oriented in the direction of the pushing assembly. After the terminal falls into the reversing groove, the pushing assembly continues to advance, so that the terminal can be flipped 90 degrees in the direction away from the pushing groove, thereby adjusting the pin to an upward state, reducing the situation where the pins abut against each other and bend during subsequent material collection.

[0020] Optionally, the pushing assembly includes a moving seat slidably arranged on the surface of the material receiving platform, a first element arranged on the material receiving platform to drive the moving seat to slide, a pushing plate slidably arranged on the moving seat, a second element arranged on the moving seat to drive the pushing plate to move, and a pushing rod arranged on the lower surface of the moving seat; the material receiving platform is provided with a long groove for the movement of the pushing rod, and when the first element drives the moving seat to move toward the direction close to the material collecting platform, the pushing plate pushes the terminal to abut against the two positioning columns, and at this time the pushing rod can abut against the sliding seat.

[0021] By adopting the above technical solution, the moving seat moves, so that the push plate pushes the terminal to slide, and when the terminal abuts against the two positioning columns, the pushing rod abuts against the sliding seat, so that the terminal and the positioning column slide synchronously, and when the positioning column rotates subsequently, the terminal also moves forward synchronously and will not be affected by the force of the positioning column, thereby reducing terminal scratches and the like.

[0022] Optionally, the material collection table includes a support plate flush with the baffle plate and a material collection plate slidably inserted into the support plate. When collecting materials, the upper surface of the material collection plate is flush with the upper surface of the material receiving table.

[0023] By adopting the above technical solution, the power member drives the collecting plate to slide, so that the terminals on the collecting plate fall onto the conveyor belt assembly in batches.

[0024] Optionally, a rotating roller is rotatably provided on the upper surface of the material receiving platform, and a rotating axis of the rotating roller is perpendicular to a sliding direction in which the terminal slides onto the material receiving platform.

[0029] The following is combined with Figure 1-9 This application is described in further detail.

[0030] The present application embodiment discloses a pin insertion machine. Figure 1 and Figure 2The pin insertion machine includes a pin insertion device 2 and a receiving device 4. The housing and the pin of the terminal 1 are assembled together through the pin insertion device 2, and are successively bent, shaped, and then slide out from the discharge position of the pin insertion device 2. The specific structure of the pin insertion device 2 is a prior art and is not the focus of this application, so it will not be described in detail here. The receiving device 4 is located at the discharge position of the pin insertion device 2. After the terminal 1 slides out of the pin insertion device 2, it is collected and discharged by the receiving device 4.

[0031] Reference Figure 1 and Figure 2 The receiving device 4 includes a conveyor belt assembly 41, and a receiving platform 42 and a collecting platform 43 installed on the conveyor belt assembly 41. The conveyor belt assembly 41 includes a frame 411 and a conveyor belt 412 that is transmission-mounted on the frame 411. The receiving platform 42 and the collecting platform 43 are located directly above the conveyor belt 412. The receiving platform 42 is connected to the frame 411 by means of a support rod. The receiving platform 42 corresponds to the discharging position of the pin insertion device 2, and the terminal 1 processed by the pin insertion device 2 slides onto the receiving platform 42. Combined with Figure 3 and Figure 4 A baffle 6 extending upward is fixed on the receiving platform 42 at a position away from the pin insertion device 2, and the baffle 6 can block the terminal 1. A buffer pad can also be bonded on the baffle 6 to reduce the force of the terminal 1 hitting the baffle 6, and better enable the terminal 1 to stop when it collides with the baffle 6. Furthermore, a rotating roller 22 is rotatably provided on the upper surface of the receiving platform 42, and the rotating axis of the rotating roller 22 is perpendicular to the sliding direction of the terminal 1 sliding on the receiving platform 42. Under the action of the rotating roller 22, the friction of the terminal 1 when sliding can be reduced. Multiple rotating rollers 22 can be provided as required, and two are provided in this embodiment.

[0032] Reference Figure 2 The material receiving platform 42 is provided with a pushing assembly 5, and the terminals 1 slide onto the material receiving platform 42 one by one, and are pushed onto the material collecting platform 43 one by one by the pushing assembly 5. A plurality of trays 3 are placed at intervals on the conveyor belt 412, and the trays 3 are located under the material collecting platform 43 one by one. When a batch of terminals 1 are collected on the material collecting platform 43, the material collecting platform 43 transfers the terminals 1 to the trays 3, so that the trays 3 can collect the terminals 1 in batches, and then carry out subsequent quality inspection, packaging and other processes by the staff.

[0033] Reference Figure 3 and Figure 4, two positioning columns 7 are slidably installed on the receiving platform 42, and the upper ends of the positioning columns 7 have portions that extend beyond the surface of the receiving platform 42, and the sliding direction of the positioning columns 7 is the same as the pushing direction of the pushing assembly 5. A clearance groove 8 for the positioning columns 7 to slide is provided on the receiving platform 42. The space between the positioning columns 7 and the pushing assembly 5 corresponds to the discharge position of the pin device 2, and the terminal 1 can slide into this area, and then the pushing assembly 5 pushes the terminal 1 to slide in the direction close to the collecting platform 43. The terminal 1 can abut against the two positioning columns 7, so that the terminal 1 can be adjusted to a length direction that is perpendicular to the length direction of the baffle 6. The continued movement of the pushing assembly 5 can drive the positioning column 7 to move in the clearance groove 8, and the positioning column 7 and the receiving platform 42 are linked, so that the positioning column 7 can rotate in the direction close to the collecting platform 43 during the sliding process, so that the positioning column 7 is received in the clearance groove 8, and the pushing assembly 5 can push the terminal 1 onto the collecting platform 43. Combined with Figure 5 A reset member 28 is also installed on the material receiving platform 42. When the pushing assembly 5 returns to its original position, the reset member 28 can drive the positioning column 7 to reset.

[0034] Reference Figure 5 and Figure 6 A sliding seat 9 is slidably disposed on the lower surface of the material receiving platform 42, and a rotating column 10 is rotatably disposed in the sliding seat 9. Figure 7 The side wall of the sliding seat 9 is provided with a slot 11, and the slot 11 corresponds to the positioning column 7 one by one. The lower end of the positioning column 7 passes through the slot 11 and is connected to the rotating column 10. The two ends of the rotating column 10 pass through the ends of the sliding seat 9, and a gear 13 is coaxially fixed. A rack 12 is fixed to the lower surface of the receiving platform 42, and the rack 12 is located below the gear 13. After the pushing assembly 5 pushes the terminal 1 to abut against the two positioning columns 7, the pushing assembly 5 also partially abuts against the sliding seat 9, and simultaneously pushes the sliding seat 9 and the terminal 1 to slide, so that at this time the positioning column 7 will no longer apply a force to the terminal 1.

[0035] Furthermore, two parallel slide bars 25 are fixed on the lower surface of the material receiving platform 42, and a slider 27 is fixed on the upper surface of the sliding seat 9. The slide bars 25 are provided with a slide groove 26 for the slider 27 to slide. The slider 27 is a dovetail structure, and the slide groove 26 and the slider 27 are adapted. The reset member 28 is a spring and is installed in the slide groove 26. One end of the spring abuts against the end surface of the slide groove 26, and the other end abuts against the side wall of the slider 27. When the sliding seat 9 is pushed by the material pushing assembly 5 to slide, the spring is compressed.

[0036] Reference Figure 4 and Figure 5The push assembly 5 includes a moving seat 51 slidably arranged on the surface of the material receiving platform 42, a first element 52 installed on the material receiving platform 42 and used to drive the moving seat 51 to move, a push plate 53 arranged on the moving seat 51, a second element 54 arranged on the push plate 53 and used to drive the push plate 53 to move horizontally, and a push rod 55 arranged on the lower surface of the moving seat 51, and the push rod 55 is an L-shaped structure. The material receiving platform 42 is provided with a long groove 21, and the push rod 55 passes through the long groove 21 and is located on the lower surface of the material receiving platform 42. The push rod 55 extends in the direction of the sliding seat 9. The first element 52 and the second element 54 can both be multi-section cylinders.

[0037] After the terminal 1 slides onto the material receiving platform 42, the first component 52 drives the moving seat 51 to slide, so that the push plate 53 pushes the terminal 1 to slide and abuts against the two positioning columns 7, and the push rod 55 moves with the moving seat 51 and can abut against the sliding seat 9. When the terminal 1 abuts against the two positioning columns 7, the end of the push rod 55 abuts against the sliding seat 9, so when the moving seat 51 continues to move, the positioning column 7 will not apply force to the terminal 1. As the sliding seat 9 continues to slide, the gear 13 and the rack 12 engage, and the positioning column 7 can rotate in the direction close to the material collecting platform 43 and be stored in the clearance groove 8. Then the second component 54 drives the push plate 53 to move, push the terminal 1 onto the material collecting platform 43, and the terminals 1 on the material collecting platform 43 abut against each other to collect the materials one by one. Since the existing pin insertion device 2 is completed, the pins are horizontally oriented when the terminal 1 slides onto the material receiving platform 42. In this embodiment, the pusher assembly 5 is located in the direction of the plug pin of the terminal 1 , and the pusher plate 53 is in an L-shaped structure, so that the pusher plate 53 can abut against the lower half of the terminal 1 without abutting against the plug pin.

[0038] Reference Figure 6 and Figure 7 , a waist-shaped groove 14 is provided on the sliding seat 9, and the rotating column 10 is located in the waist-shaped groove 14 and can move up and down in the waist-shaped groove 14. A first pusher 15 is provided on the upper surface of the sliding seat 9, and a second pusher 16 is provided on the lower surface of the sliding seat 9. The second pusher 16 drives the rotating column 10 to abut against the inner top surface of the waist-shaped groove 14, thereby limiting the rotation of the positioning column 7 at this time. Therefore, when the terminal 1 abuts against the two positioning columns 7, the rotation of the positioning columns 7 can be reduced.

[0039] A resistance bar 17 is fixed to the lower surface of the material receiving platform 42, and the resistance bar 17 cooperates with the first push member 15. When the push rod 55 starts to push the sliding seat 9 to slide, the resistance bar 17 drives the first push member 15 to move downward and pushes the rotating column 10 to move downward. After the gear 13 moves downward, it can mesh with the rack 12.

[0040] Reference Figure 6 and Figure 7The first push member 15 includes a first push rod 151 that slides through the surface of the sliding seat 9 and a first elastic member 152 that is sleeved on the outer wall of the first push rod 151. The first elastic member 152 is a spring, and one end of the spring is connected to the end of the first push rod 151, and the other end abuts against the surface of the sliding seat 9. An annular groove 19 is provided on the outer wall of the rotating column 10, and the end of the first push rod 151 extends into the annular groove 19, and the width is adapted to the width of the annular groove 19, so that the rotating column 10 cannot move horizontally in the waist-shaped groove 14. An inclined abutment surface 18 is provided at the end of the abutment strip 17, and the upper end of the first push rod 151 abuts against the abutment surface 18, so that the first push rod 151 moves downward to push the rotating column 10 to move downward, and at this time the first elastic member 152 is compressed.

[0041] The second push member 16 includes a second push rod 161 slidably disposed on the lower surface of the sliding seat 9 and a second elastic member 162 disposed on the outer wall of the second push rod 161. The second elastic member 162 is a spring, and one end of the spring is connected to the lower surface of the sliding seat 9, and the other end is connected to the end of the second push rod 161. The second elastic member 162 is in a stretched state, thereby providing a force for the second push rod 161 to move upward. The upper end of the second push rod 161 extends into the annular groove 19, and under the action of the second elastic member 162, it can drive the rotating column 10 to move upward and abut against the inner top surface of the waist-shaped groove 14. The inner top surface of the waist-shaped groove 14 is set to a rough structure, such as anti-slip grooves, and when the rotating column 10 abuts against the inner top surface of the waist-shaped groove 14, the rotating column 10 is not easy to rotate.

[0042] Reference Figure 3 and Figure 8 A reversing groove 20 is provided on the upper surface of the material receiving platform 42. The length of the reversing groove 20 is greater than the length of the terminal 1, so that the terminal 1 can fall into the reversing groove 20. The position of the reversing groove 20 is located in the second half of the movement of the positioning column 7. That is, when the positioning column 7 moves to the position of the reversing groove 20, the positioning column 7 has been rotated downward and stored in the yielding groove 8. The depth of the reversing groove 20 gradually becomes shallower in the direction close to the material collecting platform 43. When the terminal 1 is opened and falls into the reversing groove 20, the pushing plate 53 continues to push the terminal 1, and the terminal 1 can be flipped 90 degrees, so that the pin of the terminal 1 becomes facing upward. Therefore, when the terminal 1 is pushed onto the material collecting platform 43 again, the pins between adjacent terminals 1 will not abut each other.

[0043] Reference Figure 3 and Fig. 9The material collecting platform 43 includes a support plate 431 and a material collecting plate 432 that slides horizontally through the support plate 431, and one end of the material collecting plate 432 abuts against the material receiving platform 42. The support plate 431 is connected to the frame 411 through a lifting member 23. The lifting member 23 can be a cylinder or a linear electric cylinder, which is used to drive the support plate 431 to move up and down. When collecting materials, the support plate 431 is flush with the baffle 6, and the upper surface of the material collecting plate 432 is flush with the upper surface of the material receiving platform 42. The material collecting plate 432 passes through the support plate 431 horizontally, and a power member 24 is provided on the outer wall of the support plate 431. The power member 24 is preferably a cylinder, and the cylinder body of the cylinder is fixed to the side wall of the support plate 431, and the piston rod is connected to the material collecting plate 432. When a predetermined number of terminals 1 are collected on the collecting plate 432 , the lifting will drive the supporting plate 431 to move downward, and then the power member 24 drives the collecting plate 432 to slide, so that the terminals 1 fall into the tray 3 .

[0044] The implementation principle of a pin insertion machine in an embodiment of the present application is as follows: the terminal 1 slides onto the receiving platform 42, the pushing plate 53 pushes the terminal 1 to a position abutting the positioning column 7, so that the terminal 1 is adjusted to a flush state, the pushing assembly 5 continues to move, so that the positioning column 7 rotates and is accommodated in the make way groove 8, and finally the second element 54 drives the pushing plate 53 to push the terminal 1 onto the collecting platform 43.

[0045] 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.
