They are usually composed of a piece of metal plug sealed in insulating plastic, with holes at both ends for inserting wires and tightening or loosening with screws. Terminal blocks are widely used, especially in the power industry. They are widely used in the connection of various equipment and systems, such as terminal blocks, terminal boxes, etc., in daily life, industrial production, and electronic products.

[0003] The terminals on the PCB refer to the connection points located on the printed circuit board. They are responsible for transmitting and distributing power and signals between electronic components. The terminals on the PCB adopt various standard types, such as dual in-line, surface mount leadless packages, and leaded pin arrays.

DETAILED DESCRIPTION

[0063] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0064] Embodiment 1, as Figures 1 to 9 As shown, this embodiment proposes a PCB circuit board terminal assembly device, including a fixed frame 1, a feeding frame 2 is installed on the side of the fixed frame 1, including a rotating disk frame 3, an intermittent transmission component, a feeding component, a feeding correction component, a trough body 4 and a self-positioning clamping component, the rotating disk frame 3 is rotatably installed on the upper part of the fixed frame 1, the intermittent transmission component is installed inside the fixed frame 1, and is used to drive the rotating disk frame 3 to rotate intermittently, the intermittent transmission component includes an intermittent gear 5, a motor 6 and a driving gear 7, the intermittent gear 5 is rotatably installed inside the fixed frame 1, the intermittent gear 5 is fixedly connected to the rotating disk frame 3, the motor 6 is fixedly installed inside the fixed frame 1, the driving gear 7 is fixedly installed at the output end of the motor 6, and the driving gear 7 is meshed with the intermittent gear 5.

[0065] Specifically, when assembling and processing the PCB circuit board terminals, first place the PCB circuit board to be processed and the terminal to be installed on the loading assembly, use the loading assembly to move the PCB circuit board to the clamping position in sequence, and then place it on the self-positioning clamping assembly on the slot body 4. At this time, start the motor 6, the motor 6 drives the driving gear 7 to rotate, and the driving gear 7 drives the intermittent gear 5 to rotate intermittently. The number of times the intermittent gear 5 stops rotating each time it rotates one circle is the same as the number of the slot bodies 4, that is, each time the intermittent gear 5 stops rotating, it can drive the corresponding slot body 4 on the rotating disc frame 3 to move to the corresponding position, and then place the corresponding PCB circuit board on the self-positioning clamping assembly on the corresponding slot body 4 and fix it. With the rotation of the rotating disc frame 3, when the clamped PCB circuit board is moved to the position of the loading correction assembly, the terminal blocks moved to the specified positions in sequence are clamped, and under the action of the loading correction assembly, the pin parts of the terminal blocks are straightened to improve the assembly accuracy and quality. After the corresponding terminal blocks are assembled at the specified positions on the PCB circuit board, they are welded and collected.

[0066] like Figure 1As shown, the loading assembly is installed on the loading frame 2 for loading, and the loading assembly includes a first loading device 8, which is fixedly installed on the loading frame 2, and a feeding frame 9 is fixedly installed on the side of the fixed frame 1, and a second loading device 10 is fixedly installed on the feeding frame 9, and also includes a loading robot arm 11, a feeding robot arm 12, a clamping claw 13 and a correction frame 14. The loading robot arm 11 is fixedly installed on the loading frame 2, and the loading robot arm 11 is located on one side of the first loading device 8, and a feeding robot arm 12 is fixedly installed on the feeding frame 9, and the feeding robot arm 12 is located on one side of the second loading device 10, and the working ends of the loading robot arm 11 and the feeding robot arm 12 are fixedly installed with a clamping claw 13, and the second loading device 10 is fixedly installed with a correction frame 14.

[0067] Specifically, during the loading process, the PCB circuit boards are placed on the first loading device 8 in sequence, and the first loading device 8 is started to transport the PCB circuit boards. At the same time, the wiring terminals are placed on the second loading device 10 in sequence, and the second loading device 10 is started to transport the wiring terminals. At this time, the loading robot arm 11 is started. As the rotating disc rack 3 rotates, the PCB circuit boards are placed on the fixed grooves 22 in sequence through the setting of the clamping claws 13. As the rotating disc rack 3 rotates, until the corresponding PCB circuit board moves to the position of the feeding frame 9, the feeding robot arm 12 is started to move the wiring terminals to the upper part of the corresponding PCB circuit board, find the installation position, and install the wiring terminals on the PCB circuit board.

[0068] like Figure 3 , Figure 4 As shown, the feeding correction component is installed on the feeding component and is used for feeding. The feeding correction component includes a support plate 15, a first electric cylinder 16, a top frame 17, a shell 18, a torsion spring 19 and a strip protrusion 20. The support plate 15 is fixedly installed on the correction frame 14. Two first electric cylinders 16 are fixedly installed on the correction frame 14. The output ends of the two first electric cylinders 16 are fixedly installed with a top frame 17. The shells 18 are rotatably installed on the two top frames 17. Torsion springs 19 are fixedly installed at both ends of the inside of the shell 18. The end of the torsion spring 19 away from the shell 18 is fixedly connected to the top frame 17. A plurality of strip protrusions 20 are fixedly arranged at equal distances on the two shells 18.

[0069] Specifically, when the feeding robot arm 12 uses the clamping claw 13 to clamp the terminal block on the second feeding device 10, the terminal block is first placed on the support plate 15 so that the multiple pins in the two bottom rows of the terminal block are located on both sides of the support plate 15. At this time, the two first electric cylinders 16 are started, and the first electric cylinders 16 push the top frame 17 to move, and the top frame 17 pushes the outer shell 18 to move until the multiple strip protrusions 20 on the outer shell 18 abut against the pins of the terminal block. At this time, with the action of the first electric cylinder 16, the top frame 17 pushes the outer shell 18 to continue to move. At this time, the torsion spring 19 is twisted, and the top frame 17 and the outer shell 18 rotate relative to each other, so that the pin part of the pin of the terminal block is combed and corrected through the strip protrusion 20, so that its position is more neat and easy to install. When the outer shell 18 moves to the required position, the terminal block can be pulled out from the top, thereby further combing the pin part of the terminal block.

[0070] like Figures 5 to 9 As shown, a plurality of grooves 4 are provided at equal angles in a circular shape on the rotating disk frame 3, and a self-positioning clamping assembly is installed on each groove body 4 for clamping the circuit board. The self-positioning clamping assembly comprises a positioning frame 21, a fixing groove 22, a side slide frame 23, a mounting frame 24, a fixing portion and a driving portion. A positioning frame 21 is fixedly installed on each groove body 4, a fixing groove 22 is fixedly installed on each positioning frame 21, side slide frames 23 are fixedly installed on both sides of each positioning frame 21, a mounting frame 24 is fixedly installed between the two side slide frames 23 on both sides of each positioning frame 21, a fixing portion is installed inside each side slide frame 23 for fixing the circuit board, and a driving portion is installed on each mounting frame 24 for driving the fixing portion.

[0071] Specifically, after the PCB circuit board is placed on the fixing groove 22, the driving part is started to drive the fixing part to move, so as to clamp the PCB circuit board. During the movement, the relative position of the PCB circuit board and the fixing groove 22 is corrected during the process of fixing the PCB circuit board through the setting of the fixing part, thereby improving the stability of the installation.

[0072] The above, such as Figure 8 As shown, the fixed part includes a positioning slide groove 25, a sliding frame 26 and a mounting groove 27. Two positioning slide grooves 25 are symmetrically opened on each positioning frame 21. A sliding frame 26 is slidably installed inside each positioning slide groove 25. A mounting groove 27 is opened inside each sliding frame 26. It also includes a clamping frame 28 and a spring 29. A clamping frame 28 is slidably installed inside each mounting groove 27. The two clamping frames 28 in each positioning frame 21 are symmetrically arranged. The working section of each clamping frame 28 is set as an inclined plane. Multiple springs 29 are fixedly installed at equal distances in each mounting groove 27, and the multiple springs 29 are fixedly connected to the clamping frame 28.

[0073] Specifically, when the PCB circuit board in the installation groove 27 is clamped, the sliding frame 26 moves on the positioning sliding groove 25, and the sliding frame 26 drives the clamping frame 28 in the installation groove 27 to move until the inclined surface of the clamping frame 28 abuts against the PCB circuit board, thereby correcting the position of the PCB circuit board. Under the action of the spring 29, when the clamping frame 28 abuts against the PCB circuit board, the spring 29 is compressed to a certain extent, thereby facilitating stable clamping of the PCB circuit board and reducing the possibility of the PCB circuit board being crushed.

[0074] The above, such as Fig. 9 As shown, the driving part includes a second electric cylinder 30, a pushing frame 31 and a connecting frame 32. The second electric cylinder 30 is fixedly installed on each mounting frame 24. The pushing frame 31 is slidably installed between the two side sliding frames 23 on both sides of each positioning frame 21. The pushing frame 31 is fixedly connected to the output end of the second electric cylinder 30. The bottom of each sliding frame 26 is fixedly installed with a connecting frame 32. The side of the connecting frame 32 away from the sliding frame 26 is set as an inclined surface, and also includes a pushing slide groove 33, a push rod 34 and a convex ridge 35. A pushing slide groove 33 is opened on the inclined surface of each connecting frame 32. A push rod 34 is symmetrically and fixedly installed on each pushing frame 31. Each push rod 34 is set at an inclined surface at one end away from the connecting frame 32. A convex ridge 35 is fixedly installed on the inclined surface of each push rod 34. Multiple convex ridges 35 are respectively slidably connected with multiple pushing slide grooves 33.

[0075] Specifically, when clamping the PCB circuit board in the fixing groove 22, the corresponding second electric cylinder 30 is started, and the second electric cylinder 30 pushes the pushing frame 31 to move, and the pushing frame 31 pushes the push rod 34 to move, and the push rod 34 pushes the sliding frame 26 through the setting of the inclined surface through the connecting frame 32, and the sliding connection between the push rod 34 and the connecting frame 32 can be realized by cooperating with the convex ridge 35 on the inclined surface of the moving push rod 34 and the pushing slide groove 33 on the inclined surface of the connecting frame 32. When the pushing frame 31 moves, the sliding frame 26 can be pushed to move, and when the pushing frame 31 is reset, the sliding frame 26 can also be moved back to its original position.

[0076] To sum up, when assembling and processing the PCB circuit board terminals, first place the PCB circuit board to be processed and the terminal to be installed at the designated position, place the PCB circuit board on the first loading device 8 in sequence, start the first loading device 8 to transport the PCB circuit board, and at the same time place the terminal on the second loading device 10 in sequence, start the second loading device 10 to transport the terminal, and then start the loading robot arm 11, and through the setting of the clamping claw 13, place the PCB circuit board on the fixing groove 22 in sequence to fix it.

[0077] The second electric cylinder 30 is started at this time, and the second electric cylinder 30 pushes the pushing frame 31 to move, and the pushing frame 31 pushes the push rod 34 to move. The push rod 34 pushes the sliding frame 26 through the setting of the inclined surface through the connecting frame 32. The convex ridge 35 on the inclined surface of the moving push rod 34 cooperates with the pushing slide groove 33 on the inclined surface of the connecting frame 32 to realize the sliding connection between the push rod 34 and the connecting frame 32. Through the movement of the sliding frame 26 on the positioning slide groove 25, the sliding frame 26 drives the clamping frame 28 in the mounting groove 27 to move until the inclined surface of the clamping frame 28 abuts against the PCB circuit board, thereby correcting the position of the PCB circuit board. Under the action of the spring 29, when the clamping frame 28 abuts against the PCB circuit board, the spring 29 is compressed to a certain extent, thereby facilitating the stable clamping of the PCB circuit board and reducing the possibility of the PCB circuit board being crushed.

[0078] At this time, the motor 6 is started, and the motor 6 drives the driving gear 7 to rotate, and the driving gear 7 drives the intermittent gear 5 to rotate intermittently. The number of times the intermittent gear 5 stops rotating each time it rotates one circle is the same as the number of slots 4, that is, each time the intermittent gear 5 stops rotating, it can drive the corresponding slot 4 on the rotating disc frame 3 to move to the corresponding position.

[0079] As the rotating disc rack 3 rotates, until the corresponding PCB circuit board moves to the position of the feeding rack 9, the feeding robot arm 12 is started to move the wiring terminal to the upper part of the corresponding PCB circuit board, find the installation position, and install the wiring terminal on the PCB circuit board.

[0080] Before moving the terminal block to the upper part of the corresponding PCB circuit board, the terminal block is first placed on the support plate 15 so that the multiple pins in the two rows at the bottom of the terminal block are located on both sides of the support plate 15. At this time, the two first electric cylinders 16 are started, and the first electric cylinders 16 push the top frame 17 to move, and the top frame 17 pushes the shell 18 to move until the multiple strip protrusions 20 on the shell 18 abut against the pins of the terminal block. At this time, with the action of the first electric cylinder 16, the top frame 17 pushes the shell 18 to move continuously, and the torsion spring 19 is twisted at this time, and the top frame 17 and the shell 18 rotate relative to each other, so that the pin part of the pin of the terminal block is combed and corrected through the strip protrusion 20, so that its position is more neat and easy to install. When the shell 18 moves to the required position, the terminal block can be pulled out from the top, so as to further comb the pin part of the terminal block. After the corresponding terminal block is assembled at the specified position on the PCB circuit board, it is welded and collected.

[0081] Embodiment 2: Based on a PCB circuit board terminal assembly device, this embodiment 2 also proposes a PCB circuit board terminal assembly method, including the following steps:

[0082] The first step is to place the PCB circuit boards on the first loading device 8 in sequence, and start the first loading device 8 to transport the PCB circuit boards.

[0083] The second step is to discharge the materials synchronously, and place the connecting terminals on the second feeding device 10 in sequence, and start the second feeding device 10 to transport the connecting terminals.

[0084] The third step is loading. At this time, the loading robot arm 11 is started, and the PCB circuit boards are placed on the fixing grooves 22 in sequence through the setting of the clamping claws 13.

[0085] The fourth step is pushing, starting the corresponding second electric cylinder 30, and the second electric cylinder 30 pushes the pushing frame 31 to move.

[0086] The fifth step is ejection. The push frame 31 pushes the ejector rod 34 to move. The ejector rod 34 pushes the sliding frame 26 to move through the connecting frame 32 through the setting of the inclined surface.

[0087] The sixth step is correction. The sliding frame 26 drives the clamping frame 28 in the installation groove 27 to move until the inclined surface of the clamping frame 28 abuts against the PCB circuit board, thereby correcting the position of the PCB circuit board.

[0088] The seventh step is clamping. Under the action of the spring 29, when the clamping frame 28 abuts against the PCB circuit board, the spring 29 is compressed to a certain extent, thereby facilitating stable clamping of the PCB circuit board and reducing the possibility of the PCB circuit board being crushed.

[0089] The eighth step is to rotate and start the motor 6. The motor 6 drives the driving gear 7 to rotate, and the driving gear 7 drives the intermittent gear 5 to rotate intermittently. The number of times the intermittent gear 5 stops rotating each time it rotates one circle is the same as the number of slots 4. That is, each time the intermittent gear 5 stops rotating, it can drive the corresponding slot 4 on the rotating disc frame 3 to move to the corresponding position.

[0090] The ninth step is to move, as the rotating disc rack 3 rotates, until the corresponding PCB circuit board moves to the position of the feeding rack 9.

[0091] The tenth step is placement, placing the terminal block on the support plate 15 so that the multiple pins in the two rows at the bottom of the terminal block are located on both sides of the support plate 15.

[0092] The eleventh step is starting. At this time, the two first electric cylinders 16 are started. The first electric cylinders 16 push the top frame 17 to move, and the top frame 17 pushes the shell 18 to move until the multiple strip protrusions 20 on the shell 18 abut against the pins of the terminal.

[0093] The twelfth step is correction. The top frame 17 pushes the shell 18 to move continuously. At this time, the torsion spring 19 is twisted, and the top frame 17 and the shell 18 rotate relative to each other, so that the pin part of the terminal pin is combed and corrected through the strip protrusion 20, so that its position is more neat and easy to install. When the shell 18 moves to the required position, the terminal can be pulled out from the top, so as to further comb the pin part of the terminal pin.

[0094] The thirteenth step is assembly. Start the feeding robot arm 12 and move the connecting terminal to the upper part of the corresponding PCB circuit board. After assembling the corresponding connecting terminal at the designated position on the PCB circuit board, weld it.

[0095] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
