[0002] There are many kinds of packaging forms for electronic components, and the installation methods of components with different packaging forms on PCB boards are also different. Traditional electronic components are mostly pin-type and large in size. For such components, holes need to be drilled on the PCB board before they can be installed. The component pins pass through the drilled holes and are soldered to the pads on the other side of the PCB board. After soldering, the excess pins need to be cut off. Of course, there are also electronic components that are installed on the PCB board using leads, such as electronic components such as speakers or buzzers.

[0003] The lead wires of existing speakers or buzzers are thin copper wires, and insulating rubber skin is wrapped around the thin copper wires. In this way, the distribution and direction of the lead wires are mostly unstable. Therefore, when assembling existing electronic components with leads, most of them need to manually guide the leads of the electronic components in a fixed direction, and then fix the leads and the conveyed tin sheets together, and finally heat the PCB board to melt the tin sheets and then re-condense to realize the assembly of the electronic components.

[0035] The following will be combined with the drawings in 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.

[0036] like Figure 1 As shown, the present invention provides an automatic lead arrangement and assembly system for PCB board wiring components. This embodiment is used to automatically assemble electronic components with leads at fixed positions on a PCB board. The implementation method is simple and convenient, and no manual intervention is required, which can improve the production and assembly efficiency of the PCB board.

[0037] The automatic assembly system for the cable connector specifically comprises: a PCB board conveying mechanism 1, a wiring component conveying mechanism 2, a cable assembly 3 and a lead assembly assembly 4.

[0038] Among them, the PCB board conveying mechanism 1 is used to convey PCB boards with the same orientation at fixed time intervals. The time interval for each PCB board to move to the cable assembly 3 is the same, and the conveying orientation of the PCB boards is the same. Therefore, the assembly position of the cable conveyed to the cable assembly 3 is fixed, which can effectively avoid the problem of assembly position error.

[0039] The wiring component conveying mechanism 2 is vertically arranged with respect to the PCB board conveying mechanism 1 , and the wiring component conveying mechanism 2 is used for conveying a single wiring component to a PCB board at a facing position in a manner matching a single PCB board.

[0040] The wiring components are distributed on the wiring component conveying mechanism 2 in a manner that the leads are in front and the component body is in the back, and the spacing between two adjacent wiring components on the wiring component conveying mechanism 2 is the same, that is, when a PCB board is conveyed to the position of the wiring component conveying mechanism 2, the lead of a wiring component is exactly at the position to be installed on the PCB board.

[0041] The cable assembly 3 is arranged between the wiring element conveying mechanism 2 and the PCB board conveying mechanism 1. The cable assembly 3 is used to define the lead distribution position of the wiring element. The wiring element matches the lead with the installation position of the PCB board through the cable assembly 3.

[0042] The lead assembly component 4 is located above the PCB board conveying mechanism 1, and the lead assembly component 4 is used to fix the lead of the wiring component on the PCB board by extruding tin sheets, so as to realize the automatic assembly of the wiring of the PCB board.

[0043] The leads of most existing electronic components are thin copper wires, and insulating rubber skin is wrapped around the thin copper wires. In this way, the distribution and direction of the leads are mostly unstable. Therefore, during the automated lead assembly, it is necessary to first guide the leads of the electronic components in a fixed direction through the cable assembly 3, so that it is convenient to fix the leads to the PCB board together later.

[0044] Therefore, in this embodiment, a wiring assembly 3 is arranged at the end of the wiring element conveying mechanism 2. The wiring assembly 3 is used to arrange the leads of the electronic components so that the leads are close to the surface of the PCB board and are in the position to be installed on the PCB board. At this time, the lead assembly assembly 4 cuts a single tin sheet at the lead position of the wiring element by squeezing the tin sheet, and utilizes the fixed pressing between the tin sheet and the PCB board to realize the automated wiring assembly work of the PCB board.

[0045] Therefore, the present embodiment can realize the automatic assembly of the wiring components of the PCB board, without the need to manually arrange the leads of the wiring components. The wiring components, i.e., the leads of the electronic components, are automatically arranged through the wiring assembly 3, so that the leads are just above the PCB board and the leads are just at the position where the PCB board is to be assembled, thereby improving the wiring assembly efficiency of the PCB board, improving the overall work efficiency of the entire PCB board production, and shortening the production cycle.

[0046] Among them, the cable arrangement component 3 includes a guide component 31 arranged between the PCB board conveying mechanism 1 and the wiring element conveying mechanism 2, and a guide hole groove 32 for guiding the lead distribution of the wiring element is provided in the guide component 31. The diameter of the guide hole groove 32 close to the PCB board conveying mechanism 1 is smaller than the diameter close to the wiring element conveying mechanism 2, and the height of the guide hole groove 32 close to the PCB board conveying mechanism 1 is lower than the height close to the wiring element conveying mechanism 2. The lead of the wiring element passing through the guide hole groove 32 just corresponds to the installation position of the PCB board, and the lead assembly component 4 fixes the lead of the wiring element on the PCB board in sequence by extruding tin sheets.

[0047] In this embodiment, the diameter of the guide hole groove 32 decreases successively along the direction from the wiring element conveying mechanism 2 to the PCB board conveying mechanism 1. In this way, the diameter close to the wiring element conveying mechanism 2 is large, which is convenient for the lead of the wiring element to be directly inserted into the guide hole groove 32, and the diameter close to the PCB board conveying mechanism 1 is small, which is convenient for limiting the groove exit position and direction of the guide hole groove 32, thereby improving the accuracy of the later lead assembly component 4 in fixing and pressing the lead of the wiring element in sequence by squeezing the tin sheet, ensuring that the tin sheet can be completely mounted on the lead of the wiring element, and preventing the deviation between the tin sheet and the lead of the wiring element, resulting in the wiring being unpowered.

[0048] The guide assembly 31 includes a supporting base 311 arranged between the PCB board conveying mechanism 1 and the wiring element conveying mechanism 2, and a guide plate 312 hinged above the supporting base 311. A guide hole groove 32 for limiting the lead distribution of the wiring element is provided on the bottom surface of the guide plate 312. The guide hole groove 32 is used to bring at least two leads of the wiring element closer to each other or away from each other.

[0049] A power pile body 313 is provided above the bearing base 311, and a driving motor 314 is installed on the power pile body 313. A rotating disc 315 is fixedly installed on the transmission shaft of the driving motor 314. A pulling rod 316 is movably installed on the edge of the rotating disc 315, and the lower end of the pulling rod 316 is movably connected to the guide plate 312. When the driving motor 314 rotates in a circle, it drives the guide plate 312 to cyclically open and close.

[0050] After the lead wires are fixed to the PCB board by using tin sheets, the PCB board conveying mechanism 1 continues to convey the connected PCB board. Therefore, in this embodiment, the guide assembly 31 is divided into a bearing base 311 and a guide plate 312. The guide hole groove 32 is arranged on the bottom surface of the guide plate 312. Therefore, when the guide plate 312 is rotated to fit the surface of the bearing base 311, the guide hole groove 32 is used to guide at least two leads of the wiring element to approach or move away from each other.

[0051] After the lead is fixed to the PCB board with the tin sheet, the pull rod 316 is used to pull the guide plate 312 to rotate, and the guide plate 312 forms a certain angle with the surface of the supporting base 311, thereby releasing the wiring components and the PCB board, realizing the release of the PCB board with the installed wiring components and the wiring operation of the next PCB board.

[0052] One side of the carrying base 311 is at the same height as the wiring element conveying mechanism 2, and the other side of the carrying base 311 is at the same height as the upper surface of the PCB board on the PCB board conveying mechanism 1. The carrying base 311 serves as a connecting plate between the PCB board conveying mechanism 1 and the wiring element conveying mechanism 2, and the bottom surface of the guide plate 312 contacts the surface of the carrying base 311. The length of the carrying base 311 is much greater than the length of the guide plate 312, and the length of the carrying base 311 extends to the end of the PCB board conveying mechanism 1.

[0053] Furthermore, in order to avoid secondary breakage caused by suspension of the leads between the PCB board and the wiring components, the length of the supporting base 311 of the present embodiment is much greater than the length of the guide plate 312, and the length of the supporting base 311 extends to the end of the PCB board conveying mechanism 1. The supporting base 311 serves as a supporting plate for the wiring components, which can effectively prevent the pins of the PCB board and the wiring components from breaking due to gravity.

[0054] In this embodiment, the main function of the lead assembly component 4 is to cut the tin sheet on the tin bar reel by extrusion, and the tin sheet fixes the lead of the wiring component and the PCB board as a whole, thereby realizing the assembly of the wiring component and the PCB board.

[0055] The lead assembly component 4 includes a seam-aligning plate 41 arranged above the PCB board conveying mechanism 1, and a tin bar reel 42 arranged above the seam-aligning plate 41. A collection seat 43 is installed on the seam-aligning plate 41. A pushing cylinder 44 is arranged in the collection seat 43. An extrusion plate 45 is connected to the output shaft of the pushing cylinder 44. Under the action of the pushing cylinder 44, the extrusion plate 45 drives the single tin sheet on the tin bar reel 42 to be fixed and pressed against the surface of the PCB board.

[0056] A limiting frame plate 46 is provided at the edge of the seam plate 41 . Rubber rollers 47 for limiting the linear movement of the tin strip reel 42 are provided at both ends of the limiting frame plate 46 . The tin strip reel 42 moves linearly under the drive of the rubber rollers 47 .

[0057] The edge of the seam plate 41 is flush with the position of the wiring component to be installed on the PCB board. In this way, the tin sheet of the tin strip reel 42 passing through the limiting frame plate 46 is just above the position of the wiring component to be installed on the PCB board. Therefore, the tin sheet fixes the lead of the component to be installed to the PCB board under the action of the squeezing plate 45.

[0058] A tilted baffle 13 is provided on one side of the limiting frame plate 46 away from the end of the PCB board conveying mechanism 1. The tilted baffle 13 converts the horizontal tin bar reel 42 into an inclined direction, and a winding roller 14 is provided at the end of the PCB board conveying mechanism 1 for winding the remaining tin bar reel 42 after the tin sheet is cut off into a roll. The winding roller 14 is arranged in the inclined direction of the tin bar reel 42.

[0059] The remaining tin strip reel 42 after the tin sheet is cut off is rolled up on the reel 14, and the reel 14 rotates in a fixed direction under the action of the driving motor to recycle the tin strip reel to prevent the remaining tin strip reel from affecting the normal transportation of the PCB board.

[0060] It should be particularly noted that the tin bar on the tin bar reel 42 includes a solder bar and a plurality of evenly distributed tin sheets arranged on the same side of the solder bar, and the tin sheets are connected to the solder bar through a transition tin bar, so that the tin bar can be separated from the solder bar under the action of the extrusion plate 45, and fixedly pressed onto the surface of the PCB board under the extrusion action of the extrusion plate 45.

[0061] In order to reduce the friction of the tin strip on the tin strip reel 42 during the conveying process, a hollow guide vertical plate 15 is provided on one side of the limit frame plate 46 close to the end of the PCB board conveying mechanism 1, and the outer surface of the hollow guide vertical plate 15 facing the end of the PCB board conveying mechanism 1 is an arc-shaped smooth surface.

[0062] It should be noted that the pushing cylinder 44 in this embodiment can produce a slight movement. The movement direction of the tin bar rolled on the tin bar reel 42 in the limiting frame plate 46 is opposite to the conveying direction of the PCB board conveying mechanism 1. The pushing cylinder 44 first squeezes and fixes one of the leads of the wiring component away from the end of the PCB board conveying mechanism 1, and then squeezes and fixes the other lead of the wiring component close to the end of the PCB board conveying mechanism 1.

[0063] Therefore, a mounting opening 5 is provided at the upper end of the container seat 43, and a linear motor 6 is installed at one end of the mounting opening 5, a cantilever beam straight rod 7 is provided at the upper end of the mounting opening 5, and the upper end of the pushing cylinder 44 is sleeved on the outer side of the cantilever beam straight rod 7 through a through hole groove 8, and raised strips 9 are provided on both sides of the mounting opening 5, and engaging side grooves 10 that move along the raised strips 9 are provided on both sides of the pushing cylinder 44, and the linear motor 6 drives the pushing cylinder 44 to move linearly in the mounting opening 5.

[0064] The push cylinder 44 is specifically driven by the linear motor 6 to move along the installation opening 5, and under the limiting action of the suspension beam straight rod 7 and the raised strip 9, the push cylinder 44 can stably move along the installation opening 5 to avoid deviation.

[0065] A right-angle folding plate 11 is installed on the side surface of the pushing cylinder 44. The transverse dividing plate of the right-angle folding plate 11 passes through the limiting frame plate 46 and is on the upper surface of the tin strip reel 42. An annular plate 12 is provided at the end of the transverse dividing plate of the right-angle folding plate 11. The extrusion plate 45 includes an inner convex plate 451 with the same inner diameter as the annular plate 12, and an outer ring flat plate 452 with the same diameter as the annular plate 12. A conical cutter 453 is provided on the side of the annular plate 12 close to the limiting frame plate 46. The outer ring flat plate 452 presses down the extrusion plate 45 so that the conical cutter 453 cuts off the tin sheet on the tin strip reel 42, and the tin sheet is attached to the tin sheet surface under the downward pressure of the inner convex plate 451 and the extrusion plate 45.

[0066] In order to ensure the accuracy of cutting and pressing the tin sheet, the present embodiment provides a right-angle folding plate 11 on the side surface of the pushing cylinder 44 which moves synchronously with the pushing cylinder 44. Therefore, when the pushing cylinder 44 moves to fix and squeeze a single lead of the wiring element, the right-angle folding plate 11 moves synchronously with the pushing cylinder 44, and the annular plate 12 on the right-angle folding plate 11 is always on the surface of the tin sheet.

[0067] Therefore, when the cylinder 44 drives the extrusion plate 45 to press down, the outer ring flat plate 452 squeezes the annular plate 12, and the annular plate 12 uses the conical cutter 453 to cut the transition tin strip, and the cut tin sheet is attached to the surface of the tin sheet under the joint action of the inner convex plate 451 and the annular plate 12.

[0068] The working process of the automatic assembly system of this embodiment is as follows: the PCB board conveying mechanism 1 conveys a single PCB board with a fixed position and direction to the wiring element conveying mechanism 2, and uses an external pushing function or the conveying function of the wiring element conveying mechanism 2 itself to move the wiring element to the cable assembly 3. The guide hole groove 32 in the cable assembly 3 arranges the leads of the wiring element so that the leads are exactly in the position to be installed on the PCB board and are on the upper surface of the PCB board.

[0069] Then, the lead assembly component 4 transfers the solder bar to the top of the PCB board, and the tin sheets on the solder bar are uniformly located directly above the PCB board. The pushing cylinder 44 sequentially squeezes the tin sheets by moving to separate the tin sheets from the solder bar, and the tin sheets are pressed against the surface of the PCB board under the squeezing action of the pushing cylinder 44, thereby forming the tin sheets, leads and PCB board into a whole, thereby realizing the automatic assembly of the wiring components of the PCB board.

[0070] It should be noted that in order to further increase the fixing capacity between the lead and the PCB board, the PCB board can be heated at a high temperature to melt the tin sheet and then cooled, thereby achieving further assembly reinforcement operations.

[0071] Therefore, this embodiment realizes the automatic assembly of the wiring components of the PCB board. On the one hand, there is no need to manually arrange the leads of the wiring components. The wiring components, that is, the leads of the electronic components, are automatically arranged through the wiring assembly 3, so that the leads are just above the PCB board and the leads are just at the position where the PCB board is to be assembled, thereby improving the wiring assembly efficiency of the PCB board, improving the overall work efficiency of the entire PCB board production, and shortening the production cycle.

[0072] On the other hand, automatic stamping technology is used to stamp the tin sheet onto the surface of the PCB board, so that the tin sheet, lead wires and PCB board are assembled together in sequence, without the need for manual lead alignment and pressing assembly work, thus achieving fully automated assembly of the PCB board.

[0073] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
