Wiring terminal automatic processing device and processing method thereof

[0050] As an embodiment of the invention, the feeding device comprises a second rotating shaft 17 and a second motor 18, wherein the second rotating shaft 17 is rotatably installed between two second mounting brackets 16, the second motor 18 is fixed on the side wall of one of the second mounting brackets 16 by screws, the output shaft of the second motor 18 passes through the second mounting brackets 16 and is fixedly connected with the second rotating shaft 17, and the side wall of the second rotating shaft 17 is provided with a magnetic transfer mechanism. The magnetic transfer mechanism is used to transfer the copper sheet, and the copper sheet is placed into the terminal shell 50 by magnetic attraction. The side wall of the second rotating shaft 17 is provided with a pressing mechanism, which is used to press and assemble the placed terminal. The feeding device is matched with the pressing mechanism at a 90-degree angle. When working, after the second motor 18 is started, it can drive the second rotating shaft 17 to swing back and forth at an angle of 90 degrees through the output shaft. After the second rotating shaft 17 swings, it drives the magnetic transfer mechanism and the pressing mechanism to turn over. When the magnetic transfer mechanism turns over to a horizontal state, it can start the telescopic cylinder to absorb the copper sheet by magnetic force, and when the magnetic transfer mechanism turns over to a vertical state, it actively cancels the magnetic force to make the copper sheet fall into the inside of the terminal housing 50 for placement. Then, the second rotating shaft 17 turns over again to drive the pressing mechanism to turn over to the vertical state, so that the pressing mechanism presses and fixes the placed copper sheet and the terminal shell 50, thus realizing the automatic assembly processing of the copper sheet and the terminal shell 50, which is beneficial to reducing the labor force.

[0051]As an embodiment of the present invention, the magnetic transfer mechanism includes a first turning plate 19, a first fixing plate 30, a first pressure switch 33 and a wedge block 34. The first turning plate 19 is located at one side of the second rotating shaft 17, and a telescopic cylinder is fixedly connected between the side of the first turning plate 19 and the second rotating shaft 17. The first electromagnet 20 is fixed at one end of the first turning plate 19 facing away from the second rotating shaft 17. The first fixing plate 30 is fixed on the side wall of the second mounting frame 16, the first pressure switch 33 is fixed on the side wall of the second rotating shaft 17, the first pressure switch 33 is electrically connected with the first electromagnet 20, the first pressure switch 33 and the first turning plate 19 are located on the same plane, and two first springs 31 are symmetrically fixed on the side of the first fixing plate 30 facing the first pressure switch 33. One side of the two first springs 31 facing the first pressure switch 33 is jointly fixed with a first sliding plate 32, which is in pressing contact with the first pressure switch 33, and a wedge-shaped block 34 is vertically slidably connected to the side wall of the second mounting frame 16. The bottom of the wedge-shaped block 34 is fixedly connected with an electric push rod which is fixedly connected to the side wall of the second mounting frame 16, and a conveying mechanism for conveying copper sheets is installed between the first electromagnet 20 and the processing table 2. When working, the second rotating shaft 17 rotates to drive the first turning plate 19 to turn over, the first turning plate 19 drives the first electromagnet 20 to turn over, and the second rotating shaft 17 rotates to drive the first pressure switch 33 to turn over. When the first electromagnet 20 turns to a horizontal state, the first pressure switch 33 gradually presses the first sliding plate 32, and the first sliding plate 32 presses the first spring 31 to compress along with the turning and sliding of the first pressure switch 33. The first fixed plate 30 can fixedly mount the first spring 31, so that a squeezing force is generated between the first sliding plate 32 and the first pressure switch 33, thereby pressing the first pressure switch 33 to make the power supply connected, and after the power supply is connected, the first electromagnet 20 is electrified to generate a magnetic attraction force. When the first electromagnet 20 turns to a horizontal state, the first electromagnet 20 is aligned with the conveying mechanism, and the first electromagnet 20 is electrified at this time, and then the telescopic cylinder is started. When the telescopic cylinder pushes the first turning plate 19 and the first electromagnet 20 to move integrally, the magnetic attraction of the first electromagnet 20 absorbs the copper sheet conveyed by the conveying mechanism, so that the copper sheet and the first electromagnet 20 are positioned together. Then, when the first electromagnet 20 is retracted and reset, the first pressure switch 33 turns over with the rotation of the second rotating shaft 17 during the turning of the first electromagnet 20 to the vertical state. At this time, the compressed first spring 31 pushes the first pressure switch 33 and the first sliding plate 32 to squeeze each other by its own elastic force, and still maintains the energized state. At this time, the telescopic cylinder is controlled to push the first turning plate 19 and the first electromagnet 20 to move downwards, and the copper sheet on the surface of the first electromagnet 20 is sent to the interface at the top of the terminal housing 50. After the copper sheet is fed, the electric push rod is started, and the electric push rod pushes the wedge 34 to move upwards. After the first pressure switch 33 turns over and passes through the wedge-shaped block 34, the wedge-shaped block 34 keeps in contact with the first pressure switch 33 without squeezing. When the wedge-shaped block 34 moves upward, the wedge-shaped block 34 pushes up the first sliding plate 32, which separates the first pressure switch 33 from the first sliding plate 32, so that the power supply is cut off, and the magnetic attraction force of the first electromagnet 20 loses after the power is cut off, so that the adsorbed copper sheet is put down to stay at the interface of the terminal housing 50.

[0052] As an embodiment of the present invention, the conveying mechanism includes four third mounting brackets 21 and a third motor 23, two of the four third mounting brackets 21 are symmetrically fixed on the top of the processing table 2 in a group, a second rotating roller 22 is rotatably installed between two third mounting brackets 21 in the same group, and the third motor 23 is fixed on the side wall of the third mounting bracket 21 by screws. The output shaft of the third motor 23 passes through the third mounting frame 21 and is fixedly connected with one of the second rotating rollers 22. The outer rings of the two second rotating rollers 22 are jointly connected with a second conveyor belt 24. One end of the second conveyor belt 24 facing the first electromagnet 20 is sleeved with a discharge frame 25, and both ends of the discharge frame 25 are fixedly connected with the third mounting frame 21. The inner wall of the discharge frame 25 is fixedly connected with baffle plates 26 distributed in a linear array, and adjacent baffle plates 26 are formed for When working, copper sheets are placed side by side in the feeding channel in turn. Because the shape of the copper sheets and the channels of the feeding channel support each other, the copper sheets can only move along the feeding channel. Therefore, the feeding process is as follows: the third mounting frame 21 can rotatably support the second rotating roller 22, the third motor 23 can drive the second rotating roller 22 to rotate through the output shaft after starting, and the second rotating roller 22 can drive the second conveyor belt 24 to drive after rotating. The transmission of the second conveyor belt 24 can convey the copper sheets neatly, so that the copper sheets can be automatically conveyed to the inside of the discharging frame 25, and the copper sheets passing through the discharging frame 25 are actively pulled out by the first electromagnet 20 through magnetic attraction, so that the first electromagnet 20 can absorb a row of copper sheets conveyed along the second conveyor belt 24 through magnetic attraction every time it rotates to a horizontal state, which is beneficial to the automatic conveying and supplementing of copper sheets.

[0053] As an embodiment of the present invention, the pressing mechanism includes a second turning plate 27 and a second pressure switch 35. The second turning plate 27 is fixed on the side wall of the second rotating shaft 17, and both ends of the second turning plate 27 are fixed with an air cylinder 28. The output end of the air cylinder 28 is fixed with a pressing block 29, which is located directly above the first opening 3. The second pressure switch 35 is fixed on the side wall of the end of the second rotating shaft 17, and the second pressure switch 35 and the first pressure switch 35 are connected with each other. When working, the second rotating shaft 17 rotates to drive the second turning plate 27 and the second pressure switch 35 to turn over, and the second turning plate 27 turns over to drive the cylinder 28 to turn over. When the second turning plate 27 drives the cylinder 28 to turn over to the vertical state, the second pressure switch 35 squeezes the wedge-shaped block 34, so that the second pressure switch 35 is connected to the power supply to start the cylinder 28 under the squeezing action of the wedge-shaped block 34. After the cylinder 28 is started, the pressing block 29 is pushed down through the output end. The pressing block 29 pushed downward presses the copper sheet and the terminal housing 50, thus completing the installation of the terminal. In the process of pushing the terminal downward by the pressing block 29, the terminal is pushed downward through the first opening 3 by the automatic transposition device and collected, which is beneficial to the automatic processing and installation of the terminal.

[0054] As an embodiment of the invention, the automatic transposition device comprises a first groove 15, a plurality of first mounting brackets 11 and a first motor 13, wherein the first groove 15 is formed at the end of the processing table 2 facing away from the magnetic transfer mechanism, four first mounting brackets 11 are symmetrically fixed on the top of the base 1 in a group of two, a first rotating roller 12 is rotatably installed between the first mounting brackets 11 in the same group, and the first motor 13 is fixed on the side wall of the first mounting brackets 11 by screws. The output shaft of the first motor 13 is fixedly connected with one of the first rotating rollers 12, a first conveyor belt 14 is installed between the two first rotating rollers 12, one end of the first conveyor belt 14 is matched with the first groove 15, and a turnover mechanism is installed between the first opening 3 and the base 1, which is used for supporting the terminal shell 50 of the terminal and collecting the copper sheets after being pressed and installed. When working, the first mounting frame 11 can support and mount the first rotating roller 12, and the first motor 13 can drive the first rotating roller 12 to rotate through the output shaft after starting. After the first rotating roller 12 rotates, it drives the first conveyor belt 14 to convey the terminal housing 50, and the end of the first conveyor belt 14 is matched with the first groove 15. After being conveyed to the end of the first conveyor belt 14, the conveyed terminal housing 50 can smoothly enter the first opening 3 through the top of the processing table 2, and the terminal housing 50 located in the first opening 3 is supported by the turnover mechanism, so that the terminal housing 50 can be automatically loaded without manual placement and fixing of the terminal housing 50, and after assembly, the turnover mechanism turns over to convey and collect the assembled terminal downwards by the downward push of the pressing mechanism.

[0055]As an embodiment of the present invention, the turnover mechanism includes a limiting frame 4 and a second protruding strip 10. The limiting frame 4 is fixed at the bottom of the first opening 3, four corners of the bottom of the limiting frame 4 are fixed with rotating support pipes 5, a first rotating shaft 6 is rotatably installed between two rotating support pipes 5 on the same side, a torsion spring 8 is fixed between the first rotating shaft 6 and the rotating support pipes 5, and supporting plates 7 are fixed on the opposite side walls of the two first rotating shafts 6, which are located at the bottom of the limiting frame 4. The top of one supporting plate 7 is fixed with a first convex bar 9, the second convex bar 10 is fixed on the top of the base 1, and the second convex bar 10 is located right below the first convex bar 9; When working, the limiting frame 4 can extend the thickness of the first opening 3, which is beneficial to limiting the terminal housing 50. The first rotating shaft 6 can be rotatably mounted by the rotating support tube 5, the supporting plate 7 fixed on the side wall of the first rotating shaft 6 can support the terminal housing 50, and the torsion springs 8 at both ends of the first rotating shaft 6 can keep the supporting plate 7 in a horizontal state through torsional force. The first convex bar 9 and the second convex bar 10 can correspond to the terminal housing 50, and support the bottom of the terminal housing 50 to maintain the horizontal state of the terminal housing 50 in the assembling process. When the pressing mechanism pushes the terminal housing 50 for pressing, the terminal housing 50 is pushed downward and then pushes the pallet 7 to turn over, so that the terminal housing 50 is pushed through the first opening 3 and then falls to the top of the base 1, so that the assembled terminal can be automatically collected at the top of the base 1.

[0056] As an embodiment of the present invention, an L-shaped push plate 49 is fixed on the side wall of the first rotating shaft 6 near one end of the first groove 15, and the angle formed by the L-shaped push plate 49 and the supporting plate 7 is acute. The end of the base 1 facing away from the first groove 15 is provided with a second groove 45, and two third rotating rollers 46 are symmetrically installed in the second groove 45. The fourth motor 47 is fixed on the side wall of the base 1 by screws. The output shaft of the fourth motor 47 is fixedly connected with the third rotating roller 46, and a third conveyor belt 48 is jointly transmitted and connected between two third rotating rollers 46. The third conveyor belt 48 is matched with the second groove 45, and the top of the third conveyor belt 48 is at the same level as the top of the base 1. When working, after the terminals are assembled, the dropped terminals will be piled up together after they are not put away in time, which makes the pressing operation of the later assembled terminals inconvenient, and the piled-up terminals will be damaged when squeezed, which is not conducive to the processing operation of the terminals. This embodiment of the invention can solve the above problems. The specific implementation is as follows. After the fourth motor 47 is started, it can drive the third rotating roller 46 to rotate through the output shaft. After the third rotating roller 46 rotates, it drives the third conveyor belt 48 to drive. After the connecting terminal is pushed down to the top of the base 1, the pressing block 29 moves up and retracts under the drive of the air cylinder 28. After the pressing block 29 retracts, it loses its limiting function. The first rotating shaft 6 rotates and resets under the elastic force of the torsion spring 8. After the first rotating shaft 6 resets, it drives the L-shaped push plate 49 to turn over, and the L-shaped push plate 49 pushes the connecting terminal during the turning process. More parts of the wiring terminals are pushed to the top of the third conveyor belt 48, and the wiring terminals moved to the third conveyor belt 48 are transported and collected under the transmission action of the third conveyor belt 48, so that the assembled wiring terminals will not accumulate on the top of the base 1 to form obstacles, which is beneficial to improving the automatic processing efficiency of the wiring terminals.

[0057] As an embodiment of the present invention, two third fixing plates 40 are symmetrically fixed on the top of the processing table 2, which are located at both ends of the top of the first opening 3, and two third springs 41 are symmetrically fixed on opposite sides of the two third fixing plates 40. The sides of the two third springs 41 in the same group facing away from the third fixing plates 40 are respectively fixed with third sliding plates 42, and the ends of the third sliding plates 42 are provided with guide sections 4201. Two third sliding plates 42 are located at both ends of the top of the first opening 3, connecting rods 43 are fixed on opposite sides of the two third sliding plates 42, second electromagnets 44 are fixed on opposite sides of the two connecting rods 43, the second fixing plate 36 is fixed on the side wall of the second mounting frame 16, the third pressure switch 39 is fixed on the side wall of the end of the second rotating shaft 17, and two second springs 37 are symmetrically fixed on one side of the second fixing plate 36 facing the third pressure switch 39. The ends of the two second springs 37 facing away from the second fixing plate 36 are jointly fixed with a second sliding plate 38, which is slidably connected with the side wall of the second mounting frame 16, and the third pressure switch 39 is electrically connected with the second electromagnet 44. When in operation, when the terminal shell 50 is conveyed to the inside of the first opening 3, the positioning of the terminal shell 50 is unstable because it is conveyed to the inside of the first opening 3, which makes it easy for the terminal shell 50 to be offset when it is assembled with the copper sheet, which makes it difficult for the copper sheet to align with the terminal shell 50 for assembly, resulting in adverse effects on the processing of the terminal. This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: During the loading process of the terminal housing 50, the third sliding plate 42 has a guide section, which will adjust the position of the terminal housing 50. Under the action of thrust, the terminal housing 50 will be introduced into the first opening in a matching way, so as to avoid the butt offset of the terminal housing 50 during the loading process. When the first turning plate 19 turns over and drives the first electromagnet 20 with copper sheet to turn down, the rotation of the second rotating shaft 17 drives the third pressure switch 39 to turn over synchronously. After the third pressure switch 39 is turned over, it gradually approaches the second sliding plate 38, so that the third pressure switch 39 gradually squeezes the second sliding plate 38 to move, and the third pressure switch 39 is connected with the power supply after being pressed, so that the second electromagnet 44 generates magnetic force after being energized, and the two second electromagnets 44 that generate magnetic force attract each other, and the two second electromagnets 44 move to pull the two connecting rods 43 to approach each other. The connecting rod 43 drives the two third sliding plates 42 to approach each other, and the third sliding plates 42 clamp and fix the terminal housing 50 after approaching each other, so that the terminal housing 50 is fixed and positioned in the first opening 3, which is beneficial to the alignment of the terminal housing 50 and the copper sheet, so that when the first electromagnet 20 drives the copper sheet to move downward for feeding, the terminal housing 50 can be automatically fixed and positioned. After the first electromagnet 20 finishes placing the copper sheet, the second rotating shaft 17 drives the first turning plate 19 to reverse turn and reset, while the second rotating shaft 17 drives the third pressure switch 39 to synchronously turn and reset. The second spring 37 can drive the second sliding plate 38 to reset by elastic force, and gradually separates from the second sliding plate 38 after the third pressure switch 39 turns over, so that the power supply is cut off, and then the second electromagnet 44 loses its magnetic force. The two third sliding plates 42 are pulled by the third springs 41 at both ends to reset and loosen the positioning and fixing of the terminal housing 50, and the third fixing plates 40 can fix the third springs 41, so that the inside of the terminal housing 50 can position and limit the terminal housing 50 when placing copper sheets, which is beneficial to the alignment of the terminal housing 50 and the copper sheets, thus helping to avoid the adverse effects caused by the misalignment of the copper sheets during the processing of the terminal.

[0058] The invention relates to an automatic processing method of a wiring terminal, which comprises the following steps:

[0059] 1. Transmission of the terminal housing: the terminal housing 50 is transmitted to the inside of the first opening 3 by the automatic transposition device for positioning;

[0060] 2, assembling the copper sheet: absorbing the delivered copper sheet by a feeding device, so that the copper sheet is actively butted to the inside of the butt hole of the terminal housing 50 inside the first opening 3 after reaching the top of the first opening 3, and assembling the terminal housing 50 and the copper sheet;

[0061] Step 3: Assembly and transmission of the wiring terminal: after the copper sheet is placed, the copper sheet and the wiring terminal shell 50 are pressed by a pressing mechanism, and the wiring terminal is driven to squeeze through the turnover mechanism for pushing and collecting in the pressing process.

[0062]The working principle of the invention is that the plastic shell and the copper sheet of the terminal are usually assembled when the terminal is processed. In the prior art, the copper sheet is usually placed inside the terminal shell and pressed. However, in the prior art, the terminal shell needs to be manually installed and fixed during processing, so that the processing efficiency of the terminal is affected by manual operation and the processing efficiency of the terminal is reduced. This embodiment of the invention can solve the above problems. The specific implementation is as follows: the base 1 can support the whole device, the processing table 2 can be used to assemble the terminal shell 50 and the copper sheet, and the terminal shell 50 can be positioned in the first opening 3, so that the terminal shell 50 can be located just below the feeding device after being transferred to the first opening 3. Therefore, the feeding device places the copper sheet into the terminal shell 50 conveyed to the bottom to process and assemble the terminal, the second mounting frame 16 can support and install the feeding device, the automatic transposition device can automatically convey the terminal shell 50 to the inside of the first opening 3, and the terminal shell 50 and the copper sheet inside the first opening 3 are conveyed and collected downward after being assembled, which is beneficial to the automatic processing of the terminal. Therefore, it is beneficial to avoid the influence of the speed change in manual operation on the automatic processing efficiency of the wiring terminal; moreover, the effect of preventing the copper sheet from being placed many times is achieved through the turnover and rotation of the feeding device and the automatic transposition device, which is beneficial to improving the automatic processing efficiency of the wiring terminal.
