Description

Technical Field

[0001] The present invention relates to the technical field of PCB production lines, and in particular to an automatic lead arrangement and assembly system for PCB components. Background Art

[0002] There are many different ways to assemble the leads of PCB components, each with its own unique application scenarios and characteristics. In the field of electronic components, pin-type components are the mainstream, and they are usually large in size. If you want to install such components on the PCB board, you must first drill holes in the PCB board. The specific operation is to pass the leads of the components through these drilled holes, and then solder the leads to the corresponding pads on the other side of the PCB board. After the soldering process is completed, the excess leads need to be cut off to complete the entire installation process. This type of component installation method is relatively convenient, but some electronic components need to use soft copper wire as leads to be installed on the PCB board, mainly based on their own characteristics and circuit design requirements. Components such as speakers, sensors, batteries, and LED light strips often have unstable lead distribution and direction. Currently, when assembling these components, in most cases, the leads of the electronic components need to be manually guided to a fixed direction, then tinned, inserted into the mounting holes on the PCB board, and finally heated to complete the electrical connection between the component and the PCB board. However, the current installation method of these electronic components involves many manual steps; from guiding the lead direction to pressing the lead and tin sheet, the entire process relies on manual operation, resulting in slow installation and difficulty in improving work efficiency.

[0003] In response to the above problems, the prior art has proposed some solutions. For example, Chinese patent application number: CN202411324421.X discloses an automatic wiring assembly system for the leads of PCB board wiring components. This solution automatically arranges the leads of the wiring components through a wiring assembly so that the leads are exactly in the position to be assembled on the PCB board, and uses automatic stamping technology to stamp the tin sheet on the surface of the PCB board, so that the tin sheet, leads and PCB board are assembled together in sequence. There is no need for manual lead alignment and pressing assembly work, and the PCB board is fully automated. Assembly work, thereby improving the wiring assembly efficiency of the PCB board; however, the above solution still has some problems. Due to the characteristics of soft copper wire, it is easy to bend during the transmission process, resulting in the wiring component conveying mechanism being unable to ensure that the lead is accurately embedded in the guide hole groove when conveying the wiring component to the guide hole groove position, which in turn leads to a decrease in the wiring success rate of the automatic lead wiring assembly system.

[0004] To address the problem that soft copper wire is prone to bending during transportation, which causes the wiring component conveying mechanism to be unable to ensure that the lead wire is accurately embedded in the guide hole groove when conveying the wiring component to the guide hole groove position, thereby reducing the wiring success rate of the lead automatic wiring assembly system, an automatic lead wiring assembly system for PCB board components is proposed. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic wiring assembly system for the leads of PCB board components to solve the problem that soft copper wires are easily bent during the transmission process, resulting in the wiring component conveying mechanism being unable to ensure that the leads are accurately embedded in the guide hole groove when conveying the wiring components to the guide hole groove position, thereby reducing the wiring success rate of the automatic wiring assembly system.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A PCB component lead automatic wiring assembly system includes a No. 1 conveyor belt and a No. 2 conveyor belt, wherein the No. 1 conveyor belt is used to convey wiring components to be assembled, and the No. 2 conveyor belt is used to convey PCB board bodies. The No. 1 conveyor belt and the No. 2 conveyor belt are driven by a No. 1 motor and a No. 2 motor respectively. The No. 1 conveyor belt and the No. 2 conveyor belt are arranged vertically, and the installation position of the No. 1 conveyor belt is higher than the installation position of the No. 2 conveyor belt. The No. 1 conveyor belt conveys each wiring component to a single PCB board body on the No. 2 conveyor belt in a lead-first manner. A movable traction block is provided on the rear side of the No. 1 conveyor belt, and the movable traction block is close to the No. 1 conveyor belt. Two traction grooves are provided on one side, and wire blocks are respectively provided on both sides of the lower end surface of the movable traction block. A transmission component is provided on the No. 1 conveyor belt, and the transmission component is used to drive the lead to be embedded in or out of the traction groove. When the No. 1 conveyor belt conveys the wiring component to the specified position, the two wire blocks guide the lead to be embedded in the two traction grooves, and the lead is pulled into the mounting hole on the PCB board body by the movable traction block, thereby avoiding the problem that the bent lead cannot be accurately embedded in the mounting hole of the PCB board during the wiring assembly, resulting in a decrease in the wiring success rate of the automatic wiring assembly system for the lead, and ensuring the wiring accuracy of the automatic wiring assembly system for the leads of the PCB board components.

[0008] Preferably, the transmission assembly includes a mounting frame, a No. 1 slider, a No. 2 slider, a slide rod, a gear set and a pull rod, the mounting frame is installed on the side wall of the No. 1 conveyor belt, and a No. 1 slide groove and a No. 2 slide groove are provided on the mounting frame, the No. 1 slide groove is a closed triangle, the No. 2 slide groove is located at the lower side of the No. 1 slide groove, and the No. 2 slide groove is parallel to the No. 1 conveyor belt, the No. 1 slider and the No. 2 slider are slidably connected in the No. 1 slide groove and the No. 2 slide groove respectively, one end of the slide rod is rotatably connected to the mounting frame, and the connection position of the slide rod and the mounting frame is located at the center of the No. 1 slide groove, the No. 1 slider is also slidably connected to the slide rod, the gear set is used to transmit the driving force of the No. 1 motor and drive the slide rod to swing, the upper end of the pull rod is rotatably connected to the No. 1 slider, and the middle end of the pull rod is slidably connected to the No. 2 slider On the slider, the lower end face of the pull rod is connected to the upper end face of the movable traction block, and the No. 1 slide groove includes a traction section in the vertical direction, a disengagement section rising to the right and a reset section rising to the left. The initial state of the No. 1 slider is at the highest point of the traction section, and the movable traction block arranges and pulls the lead through the sliding trajectory of the No. 1 slider in the traction section. After the lead is embedded in the mounting hole of the PCB board, the movable traction block drives the movable traction block to disengage from the control of the lead through the sliding trajectory of the No. 1 slider in the disengagement section, thereby avoiding the problem that the movable traction block cannot accurately drive the lead to be embedded in the mounting hole of the PCB board during the process of arranging and pulling the lead, resulting in a decrease in the lead wiring assembly effect, thereby ensuring the stability of the automatic wiring assembly system for the leads of PCB board components during wiring.

[0009] Preferably, a fixed traction block is installed between the No. 1 conveyor belt and the No. 2 conveyor belt, and the side of the upper end of the fixed traction block close to the No. 1 conveyor belt is C-shaped and fits the No. 1 conveyor belt. Two traction grooves are provided on the side of the movable traction block close to the No. 1 conveyor belt. The two traction grooves are processed with a No. 1 guide groove on the side close to the No. 1 conveyor belt. The two No. 1 guide grooves are V-shaped and open toward the No. 1 conveyor belt. The side of the fixed traction block away from the No. 1 conveyor belt is M-shaped. When the No. 1 slider drives the pull rod to slide to the specified position, the movable traction block The side close to the No. 1 conveyor belt is fitted with the side of the fixed traction block away from the No. 1 conveyor belt. The No. 1 guide groove can ensure that the lead is embedded in the traction groove, avoiding the lead being unable to accurately enter the traction groove when the movable traction block is arranging the lead, causing the lead to deviate from the mounting hole of the PCB board. At the same time, after the movable traction block is fitted with the fixed traction block, it can avoid the lead from deviating from the mounting hole of the PCB board in the traction groove, causing the lead to deviate from the mounting hole of the PCB board, and then leading to a decrease in the lead wiring assembly effect, thereby ensuring the stability of the PCB board component lead automatic wiring assembly system during wiring.

[0010] Preferably, a plurality of traction pieces are evenly distributed in the traction groove, and the plurality of traction pieces are horseshoe-shaped, and the openings of the plurality of traction pieces are all pointing in the direction of conveyor belt No. 1, the inner circle diameters of the plurality of traction pieces are slightly smaller than the diameter of the lead, and the outer circles of the plurality of traction pieces are connected to the inner wall of the traction groove, and the plurality of traction pieces are made of rubber material, which avoids the problem that the lead slides in the traction groove during the process of the movable traction block pulling the lead, resulting in a decrease in the traction effect. At the same time, when the lead is pulled to the PCB board, the lead can slide on the traction piece by the thrust of the movable traction block, avoiding the problem that the lead cannot be embedded in the mounting hole of the PCB board at the same time, resulting in a decrease in the success rate of the automatic lead wiring assembly system, thereby ensuring the accuracy of the automatic lead wiring assembly system for PCB board components during wiring.

[0011] Preferably, two guide cylinders coaxial with the traction groove are installed on the No. 2 conveyor belt, and a conical No. 2 guide groove is provided on the upper end surface of the two guide cylinders, and the openings of the two No. 2 guide grooves are both upward. Tin plating grooves are also provided in the two guide cylinders, and the two tin plating grooves are respectively located on the lower sides of the two No. 2 guide grooves, and the two tin plating grooves are respectively connected to the two No. 2 guide grooves, thereby avoiding the problem that the lead wire ends become loose or the wire ends point to the mounting holes of the PCB board when the lead wires are embedded in the mounting holes of the PCB board, resulting in a decrease in the lead wiring assembly effect, thereby ensuring the accuracy of the automatic lead wiring assembly system for PCB board components when wiring.

[0012] Preferably, a V-shaped groove is processed on the upper end surface of the fixed traction block, and the opening of the V-shaped groove at the end close to the No. 1 conveyor belt is larger than that at the end away from the No. 1 conveyor belt, thereby avoiding the problem that the lead wire is offset when entering the traction groove, resulting in a decrease in the traction effect of the movable traction block, and ensuring the stability of the automatic wiring assembly system for the leads of PCB board components during wiring.

[0013] Preferably, a branching block is further provided on the lower end surface of the movable traction block, and the branching block is located between the two traction grooves. The lower end of the branching block is pyramidal, which avoids the problem that the leads of the wiring components cross during the transmission process, resulting in a decrease in the effectiveness of the movable traction block in arranging and pulling the leads, thereby ensuring the stability of the automatic wiring assembly system for the leads of the PCB board components during wiring.

[0014] Preferably, a guide ring is provided at the lower end of the traction groove, and the guide ring is chamfered to avoid the problem that the lower end of the movable traction block exerts pressure on the lead during the process of arranging and pulling the lead, causing damage to the lead surface, thereby ensuring the quality of the lead.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides a transmission assembly on the No. 1 conveyor belt, which is used to drive the lead wires to be inserted into or out of the traction groove. After the No. 1 conveyor belt transports the wiring component to the specified position, the two wire blocks guide the lead wires to be inserted into the two traction grooves, and the movable traction blocks pull the lead wires into the mounting holes on the PCB board body. This avoids the problem that bent leads cannot be accurately inserted into the mounting holes of the PCB board during wiring assembly, resulting in a decrease in the wiring success rate of the automatic lead wiring assembly system, thereby ensuring the wiring accuracy of the automatic lead wiring assembly system for PCB board components.

[0017] 2. The present invention evenly distributes multiple traction plates in the traction groove.

The inner circle diameters of the multiple traction plates are slightly smaller than the diameter of the lead. The outer circles of the multiple traction plates are connected to the inner wall of the traction groove. The multiple traction plates are all made of rubber material, which avoids the problem of the lead sliding in the traction groove during the process of the movable traction block pulling the lead, resulting in a decrease in the traction effect, and ensures the accuracy of the PCB board component lead automatic wiring assembly system during wiring.

[0018] 3. The present invention installs two guide cylinders coaxial with the traction groove on the No. 2 conveyor belt, and a conical No. 2 guide groove is provided on the upper end surface of the two guide cylinders.

The two tin plating grooves are respectively located on the lower sides of the two No. 2 guide grooves, and the two tin plating grooves are respectively connected to the two No. 2 guide grooves. This avoids the problem that the lead ends become loose or the lead ends point away from the mounting holes of the PCB board during the process of the lead being embedded in the mounting holes of the PCB board, resulting in a decrease in the lead wiring assembly effect, thereby ensuring the accuracy of the automatic lead wiring assembly system for PCB board components during wiring.

DETAILED DESCRIPTION

[0028] See also Figures 1 to 8 The present invention provides a PCB board component lead automatic wiring assembly system, the technical solution is as follows:

[0029] A PCB component lead automatic wiring assembly system includes a No. 1 conveyor belt 101 and a No. 2 conveyor belt 102. The No. 1 conveyor belt 101 is used to convey the wiring component 2 to be assembled, and the No. 2 conveyor belt 102 is used to convey the PCB board body 3. The No. 1 conveyor belt 101 and the No. 2 conveyor belt 102 are driven by the No. 1 motor 401 and the No. 2 motor 402 respectively. The No. 1 conveyor belt 101 and the No. 2 conveyor belt 102 are arranged vertically, and the installation position of the No. 1 conveyor belt 101 is higher than the installation position of the No. 2 conveyor belt 102. The No. 1 conveyor belt 101 conveys each wiring component 2 to a single PCB board body 3 on the No. 2 conveyor belt 102 in a lead-first manner. A movable traction block 602 is provided on the rear side of the No. 1 conveyor belt 101. The movable traction block 602 is close to the No. 1 conveyor belt 101. Two traction grooves 603 are provided on one side of the No. 1 conveyor belt 101, and wire blocks 605 are respectively provided on both sides of the lower end surface of the movable traction block 602. A transmission component is provided on the No. 1 conveyor belt 101, and the transmission component is used to drive the lead wire to be embedded in or out of the traction groove 603. When the No. 1 conveyor belt 101 conveys the wiring component 2 to the specified position, the two wire blocks 605 guide the lead wire to be embedded in the two traction grooves 603, and the lead wire is pulled into the mounting hole position on the PCB board body 3 through the movable traction block 602, thereby avoiding the problem that the bent lead wire cannot be accurately embedded in the mounting hole of the PCB board during the wiring assembly, resulting in a decrease in the wiring success rate of the automatic wiring assembly system for the lead wire, thereby ensuring the wiring accuracy of the automatic wiring assembly system for the lead wires of the PCB board components.

[0030] See also Figures 1 to 8The transmission assembly includes a mounting frame 501, a No. 1 slider 502, a No. 2 slider 503, a slide bar 504, a gear set 505 and a pull rod 506. The mounting frame 501 is mounted on the side wall of the No. 1 conveyor belt 101. The mounting frame 501 is provided with a No. 1 chute 507 and a No. 2 chute 508. The No. 1 chute 507 is a closed triangle. The No. 2 chute 508 is located below the No. 1 chute 507 and is parallel to the No. 1 conveyor belt 101. The No. 1 slider 502 The No. 1 slide 507 and the No. 2 slide 503 are respectively slidably connected to the No. 1 slide 507 and the No. 2 slide 508. One end of the slide rod 504 is rotatably connected to the mounting frame 501, and the connection position between the slide rod 504 and the mounting frame 501 is located at the center of the No. 1 slide 507. The No. 1 slide 502 is also slidably connected to the slide rod 504. The gear set 505 is used to transmit the driving force of the No. 1 motor 401 and drive the slide rod 504 to swing. The upper end of the pull rod 506 is rotatably connected to the No. 1 slide The first chute 507 is connected to the second slider 503, and the first chute 507 is connected to the second slider 503. The first chute 507 includes a traction section in the vertical direction, a disengagement section rising to the right, and a reset section rising to the left. The initial state of the first slider 502 is at the highest point of the traction section. The movable traction block 602 arranges and pulls the lead through the sliding track of the first slider 502 in the traction section. After the lead is embedded in the mounting hole of the PCB board, the movable traction block 602 drives the movable traction block 602 to disengage from the control of the lead through the sliding track of the first slider 502 in the disengagement section, thereby avoiding the problem that the pull rod 506 cannot stably move the driving force on the first motor 401 according to a specific trajectory during the process of arranging and pulling the lead by the movable traction block 602, resulting in a decrease in the lead wiring assembly effect, thereby ensuring the stability of the automatic wiring assembly system for the leads of the PCB board components during wiring.

[0031] A fixed traction block 601 is installed between the first conveyor belt 101 and the second conveyor belt 102, the upper end of the fixed traction block 601 is C-shaped and attached to the first conveyor belt 101, a V-shaped groove 8 is processed on the upper end face of the fixed traction block 601, the opening of the V-shaped groove 8 near the first conveyor belt 101 is larger than the opening far from the first conveyor belt 101, two traction grooves 603 are opened on the side of the movable traction block 602 near the first conveyor belt 101, a first guide groove 604 is processed on the side of each of the two traction grooves 603 near the first conveyor belt 101, the two first guide grooves 604 are V-shaped and the openings face the first conveyor belt 101, the side of the fixed traction block 601 far from the first conveyor belt 101 is M-shaped, when the first sliding block 502 drives the pull rod 506 to slide to the specified position, the side of the movable traction block 602 near the first conveyor belt 101 is attached to the side of the fixed traction block 601 far from the first conveyor belt 101, the first guide groove 604 can ensure that the lead wire is embedded in the traction groove 603, when the movable traction block 602 is attached to the fixed traction block 601, the traction groove 603 clamps and arranges the lead wire, avoiding the problem that when the movable traction block 602 arranges the lead wire, the lead wire cannot accurately enter the traction groove 603, causing the lead wire to deviate from the mounting hole of the PCB, and after the movable traction block 602 is attached to the fixed traction block 601, the lead wire in the traction groove 603 can avoid deviation, the lead wire deviates from the mounting hole of the PCB, and further causes the lead wire to decline in the effect of the wire arrangement assembly, ensuring the stability of the lead wire automatic wire arrangement assembly system when arranging the lead wire; a wire distribution block 901 is also arranged on the lower end face of the movable traction block 602, the wire distribution block 901 is located between the two traction grooves 603, the lower end of the wire distribution block 901 is pyramid-shaped, avoiding the problem that when the lead wire of the connecting element 2 deviates during the conveying process, the movable traction block 602 declines in the effect of arranging and pulling the lead wire; a guide ring 902 is arranged at the lower end of the traction groove 603, the guide ring 902 is processed with a rounded corner, avoiding the problem that the lower end of the movable traction block 602 presses the lead wire during the process of arranging and pulling the lead wire, causing the lead wire to be damaged.

[0032] It is worth noting that multiple traction pieces 701 are evenly distributed in the traction groove 603, and the multiple traction pieces 701 are horseshoe-shaped, and the openings of the multiple traction pieces 701 are all pointing in the direction of conveyor belt No. 1 101. The inner circle diameter of the multiple traction pieces 701 is slightly smaller than the diameter of the lead, and the outer circle of the multiple traction pieces 701 is connected to the inner wall of the traction groove 603. The multiple traction pieces 701 are made of rubber material. When the movable traction block 602 is pulling the lead, the traction piece 701 prevents the lead from sliding in the traction groove 603, resulting in a decrease in the traction effect. At the same time, when the lead is pulled to the PCB board, the lead can slide on the traction piece 701 through the thrust of the movable traction block 602, avoiding the problem that the lead cannot be embedded in the mounting hole of the PCB board at the same time, resulting in a decrease in the wiring success rate of the automatic lead wiring assembly system, thereby ensuring the accuracy of the PCB board component automatic wiring assembly system during wiring.

[0033] It is also worth noting that two guide cylinders 702 coaxial with the traction groove 603 are installed on the No. 2 conveyor belt 102. A conical No. 2 guide groove 703 is opened on the upper end surface of the two guide cylinders 702. The openings of the two No. 2 guide grooves 703 are both upward. Tin plating grooves 704 are also provided in the two guide cylinders 702. The two tin plating grooves 704 are respectively located on the lower sides of the two No. 2 guide grooves 703, and the two tin plating grooves 704 are respectively connected to the two No. 2 guide grooves 703. In the process of the movable traction block 602 moving downward, most of the lead wires are pulled out of the guide cylinders 702. The lead is in contact with the traction groove 603. At this time, the lead will be driven by the movable traction block 602 to move toward the second conveyor belt 102. Before the lead is embedded in the mounting hole of the PCB board, it needs to be corrected by the second guide groove 703 and then tinned by the tinning groove 704. This avoids the problem that the lead end becomes loose or the lead end points to the mounting hole of the PCB board during the process of embedding the lead into the mounting hole of the PCB board, resulting in a decrease in the lead wiring assembly effect, thereby ensuring the accuracy of the lead automatic wiring assembly system for PCB board components during wiring.

[0034] While working, see Figures 1 to 8After the No. 1 motor 401 drives the No. 1 conveyor belt 101 to transmit the wiring element 2 to the specified position, the No. 1 motor 401 is pushed by the electromagnetic push rod to make the No. 1 motor 401 disengage from the control of the No. 1 conveyor belt 101 and connect with the gear set 505. At this time, the No. 1 motor 401 transmits the driving force to the slide bar 504 through the gear set 505 and drives the slide bar 504 to rotate counterclockwise. When the slide bar 504 rotates, since the initial state of the No. 1 slider 502 is at the highest point of the traction section, the slide bar 504 will push the No. 1 slider 502 to slide downward in the traction section. Because the upper end of the pull rod 506 is hinged on the No. 1 slider 502 and the lower end is connected to the movable traction block 602, the No. 1 slider 502 will drive the pull rod 506 and the movable traction block 602 to move downward. At the same time, the pull rod 506 also slides downward on the second slider 503. When the movable traction block 602 is about to move to the position of the No. 1 conveyor belt 101, the wire block 605 and the branching block 901 will respectively wire and branch the leads, so that the leads are embedded in the traction groove 603 to avoid the leads from deviating or crossing, resulting in the problem that the movable traction block 602 is less effective in arranging and pulling the leads. Furthermore, the leads are embedded in the V-groove 8. In the process of the movable traction block 602 continuously pressing down, the guide ring 902 contacts the leads, and is supported by the fixed traction block 601 to push the leads into the traction groove 603, and clamp and arrange the leads to avoid the leads from deviating from the traction groove 603, causing the leads to deviate from the mounting holes of the PCB board, thereby resulting in a decrease in the lead wiring assembly effect.

[0035] Furthermore, the traction piece 701 applies pressure to the lead, and in the process of the movable traction block 602 pressing down, the lead is driven to move downward until all the leads on both sides are embedded in the tin plating groove 704 through the No. 2 guide groove 703, and the No. 1 motor 401 reverses. At this time, the upward-moving movable traction block 602 will drive the tinned leads to move upward for a certain distance. Before this, the No. 2 motor 402 is stopped, and the PCB board body 3 has not yet moved under the lead. When the movable traction block 602 drives the tinned leads to move upward for a certain distance, the No. 2 motor 402 drives the No. 2 conveyor belt 102 to drive the PCB board body 3 to move under the tinned leads. After the PCB board body 3 moves to under the tinned leads, the No. 1 motor 401 rotates forward to embed the tinned leads into the mounting holes of the PCB board body 3. After the leads are inserted into the PCB board, the leads are immediately The wire ends are welded (existing technology). Further, motor No. 101 continues to drive slider No. 102 to move in slide No. 107. At this time, slider No. 102 will drive the movable traction block 602 away from the fixed traction block 601 through the disengagement section. At the same time, the pull rod 506 pushes slider No. 503 to slide horizontally in slide No. 208, so that the movable traction block 602 is out of control of the lead. At this time, motor No. 202 drives the PCB board body 3 that has completed the cable assembly to move to the next process. Further, motor No. 101 drives slider No. 102 to return to the initial position through the reset section. Further, the electromagnetic push rod pushes motor No. 101 to disengage from the control of gear set 505, and return to its original position to drive conveyor No. 101. The cycle starts from the action of the first step to complete the automatic cable assembly work of the lead.

[0036] A specific embodiment of the present invention has been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the embodiment described above. For those skilled in the art, various changes, modifications, substitutions, and variations to these embodiments without departing from the principles and ideas of the present invention should still fall within the scope of protection of the present invention.
