Description

Technical Field

[0001] This application relates to the field of assembly equipment technology, and in particular to an assembly device for a short-circuit cap. Background Technology

[0002] As electronic devices become smaller and denser, the pin pitch of ribbon cable connectors is decreasing (e.g., from 0.5mm to 0.3mm). Figure 1 The strip-shaped metal terminal 100 and plastic part 200 shown require the plastic part and metal terminal to be inserted first during assembly. Then, the scrap strip 300 (with through holes) on one side of the metal terminal is cut off, thus completing the assembly of the shorting cap. Traditional manual assembly of shorting caps is prone to pin bending, poor contact, or electrostatic damage due to insufficient operational stability, and the efficiency is difficult to meet the needs of mass production. At the same time, the trend of industrial automation requires traceability and consistency in the production process. The early operation method that relied on manual visual positioning was not only inefficient (only a few hundred workstations could be completed per person per hour), but also led to an increased rate of misassembly due to fatigue.

[0003] The current mainstream equipment uses a four-axis SCARA robotic arm equipped with a dual-path vision system. First, the top camera performs coarse positioning of the ribbon cable connectors on the production line. Then, the side macro camera accurately identifies the pin spacing and polarity. Subsequently, the force-controlled nozzle picks up the shorting cap, and under the monitoring of the pressure sensor, the shorting cap is vertically pressed to the target pin with a constant contact force. Finally, the continuity is verified by the electrical performance probe, and the assembly results are uploaded to the MES system, achieving an assembly efficiency of over 5,000 stations per hour and a defect rate control of less than 0.1%.

[0004] However, existing equipment relies on multiple machines operating in segments, resulting in problems such as poor process connection, frequent manual transfer of semi-finished products, and poor equipment compatibility, leading to low production efficiency and high failure rate, and therefore needs to be improved. Utility Model Content

[0005] To facilitate the assembly of short-circuit caps and improve production efficiency, this application provides an assembly device for short-circuit caps.

[0006] The assembly equipment for short-circuit caps provided in this application adopts the following technical solution: An assembly device for short-circuit caps includes a base and a terminal feeding mechanism, a plastic part feeding mechanism, a conveying track, a feeding mechanism, an insertion mechanism, a cutting mechanism, and a collecting mechanism disposed on the base. The terminal feeding mechanism is used to feed strip-shaped metal terminals, and the plastic part feeding mechanism is located on one side of the terminal feeding mechanism and is used to feed plastic parts. The material conveying track is used for moving the metal terminals, and the feeding mechanism is located on the material conveying track for conveying the metal terminals; the insertion mechanism is located near the plastic part feeding mechanism and is used to insert the plastic part into the metal terminal. The cutting mechanism is located on the conveying path of the material conveying track and is used to cut the metal terminals after the plastic parts are assembled; the collecting mechanism is located on one side of the cutting mechanism and is used to collect the waste strip and the finished product respectively.

[0007] By adopting the above technical solution, during production, a terminal feeding mechanism is used to feed metal terminals. With the cooperation of the conveying track and the feeding mechanism, the strip-shaped metal terminals are transported along the conveying track. At the same time, a plastic part feeding mechanism is used to feed plastic parts. Under the action of the insertion mechanism, the plastic parts are inserted one by one into the metal terminals to complete the assembly operation of the short-circuit cap.

[0008] After assembly, the feeding mechanism continues to transport the metal terminals forward, while the shearing mechanism cuts the assembled metal terminals, separating them from the waste strip. Finally, the collection mechanism collects the waste strip and the finished product separately. The entire assembly process is highly automated, facilitating the assembly of short-circuit caps, improving production efficiency, and reducing labor intensity.

[0009] Preferably, the terminal feeding mechanism includes a rotary disk, a servo motor, a reel, and a first guide rail. The rotary disk is rotatably connected to the machine base, and the output shaft of the servo motor is connected to the rotary disk to control the periodic rotation of the rotary disk. The reel is horizontally positioned at the center of the rotary disk and is used to wind the rolled metal terminals. The first guide rail is located below the reel and is used to spread the metal terminals. Baffles are provided on both sides of the long side of the first guide rail to limit the movement of the metal terminals. The first guide rail is also provided with a limiting strip, and a gap is left between the limiting strip and the support surface of the first guide rail. After the metal terminals on the reel are unwound, they pass between the limiting strip and the first guide rail, and the metal terminals on the first guide rail are pulled onto the conveying track.

[0010] By adopting the above technical solution, strip-shaped metal terminals are wound onto a reel and rest against a rotating disk. A servo motor drives the rotating disk to rotate at a specified angle at regular time intervals, thereby driving the reel to rotate and unwinding the metal terminals. The unwound metal terminals pass through the gap between the limiting strip and the first guide rail and extend horizontally onto the conveying track for transport. The metal terminals are continuously transported along the conveying track by the feeding mechanism, achieving continuous assembly production as the metal terminals are unwound and transported simultaneously.

[0011] Preferably, the plastic part feeding mechanism includes a vibratory feeder and a second guide rail. The vibratory feeder is used to vibrate and feed the plastic part. The second guide rail is connected to the output end of the vibratory feeder and has a positioning groove for positioning the plastic part. The conveying direction of the second guide rail is parallel to the conveying direction of the first guide rail.

[0012] By adopting the above technical solution, the vibratory feeder is an automated feeding device. Its core function is to automatically sort, arrange, and orient disordered small plastic parts onto the second guide rail so that the insertion mechanism can push the plastic parts one by one onto the metal terminal.

[0013] Preferably, the insertion mechanism includes a linear cylinder, a push plate, and a guide block. The guide block is located at the end of the second guide rail and close to the material conveying track. A guide groove is provided on the guide block, which communicates with the positioning groove. The push plate is connected to the linear cylinder, and the linear cylinder is used to control the push plate to push the plastic part onto the metal terminal.

[0014] By adopting the above technical solution, when the plastic parts are oriented and sequentially conveyed onto the second guide rail, a linear cylinder controls the horizontal movement of the pusher plate. Under the action of thrust, the pusher plate can push a plastic part at the end of the second guide rail along the guide groove, so that the plastic part approaches and inserts into the metal terminal. The assembly of the plastic part and the metal terminal is achieved by the insertion force. Under the action of the vibration force of the vibratory feeder, the plastic parts on the second guide rail will be continuously replenished, so that the pusher plate can continuously push the plastic parts towards the metal terminal one by one.

[0015] Preferably, the feeding mechanism includes a plurality of feeding gears, the teeth of the feeding gears being located in the through holes of the waste belt, the feeding gears being rotated periodically by a stepper motor, the feeding gears being spaced apart along the conveying direction of the conveying track, and the conveying track being provided with a clearance groove for accommodating the teeth of the feeding gears.

[0016] By adopting the above technical solution, the stepper motor, as the drive source, can control the rotation of the feeding gear. Since the teeth of the feeding gear are engaged in the through-hole of the waste strip, the rotation of the feeding gear generates a horizontal thrust on the waste strip, achieving synchronous movement of the waste strip and the metal terminal. The presence of the clearance groove allows the feeding gear to be positioned properly, preventing any interference with its rotation.

[0017] Preferably, the cutting mechanism includes an upper cutter and a lower cutter, which are positioned opposite each other and located on the upper and lower sides of the metal terminal, respectively. The upper cutter is driven by a cylinder to punch and cut between the waste strip and the terminal.

[0018] By adopting the above technical solution, the cylinder can drive the upper cutter to move up and down. By controlling the upper cutter to cut on the lower cutter, the connection between the waste strip and the metal terminal will be broken, thereby realizing the shearing of the waste strip and the metal terminal, and thus separating the assembled finished product from the waste strip.

[0019] Preferably, the collection mechanism includes a finished product collection box and a waste collection box. The finished product collection box is located below the lower cutter and is used to collect the cut finished products. The waste collection box is located below the end of the conveying track and is used to receive the waste belt that falls on the conveying track.

[0020] By adopting the above technical solution, after the waste strip and metal terminals are cut, the finished metal terminals will fall into the finished product collection box below under the action of gravity. As for the waste strip, it will continue to move forward a distance under the action of the feeding mechanism, and then the waste strip will gradually fall into the waste collection box under its own gravity.

[0021] Preferably, it also includes a guide cylinder, which is hollow, with one end facing the end of the conveying track and the other end facing the waste collection box. The guide cylinder is used for the waste belt to pass through.

[0022] By adopting the above technical solution, the presence of the guide cylinder can guide the waste belt, making it easier for the waste belt at the end of the conveying track to fall into the waste collection box.

[0023] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a terminal feeding mechanism, a plastic part feeding mechanism, a material conveying track, a feeding mechanism, an insertion mechanism, a cutting mechanism and a collection mechanism, the various mechanisms cooperate with each other to realize the automatic assembly of short-circuit caps, improve production efficiency and reduce the labor intensity of personnel.

[0024] (2) By setting up a guide tube, the guide tube can guide the waste belt, so that the waste belt at the end of the conveying track can fall into the waste collection box in a directional manner. Attached Figure Description

[0031] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0032] This application discloses an assembly device for a short-circuit cap. (Refer to...) Figures 2 to 4 The assembly equipment includes a base 1 and, mounted on the base 1, a terminal feeding mechanism 2, a plastic part feeding mechanism 3, a conveying track 4, a feeding mechanism 5, an insertion mechanism 6, a cutting mechanism 7, and a collecting mechanism 8. The terminal feeding mechanism 2 is used to feed strip-shaped metal terminals. The plastic part feeding mechanism 3, located to one side of the terminal feeding mechanism 2, is used to feed plastic parts. The conveying track 4 is horizontally positioned for horizontal movement of the metal terminals. The feeding mechanism 5 is mounted on the conveying track 4 for conveying the metal terminals. The insertion mechanism 6, located near the plastic part feeding mechanism 3, is used to insert the plastic parts into the metal terminals on the conveying track 4. The cutting mechanism 7, located on the conveying path of the conveying track 4, is used to cut the assembled plastic parts from the metal terminals, specifically severing the connecting strip between the metal terminals and the waste strip. The collecting mechanism 8, located to one side of the cutting mechanism 7, is used to collect the waste strip and the finished product separately.

[0033] Specifically, the terminal feeding mechanism 2 includes a rotary disk 21, a servo motor 22, a reel 23, and a first guide rail 24. The rotary disk 21 is rotatably connected to the base 1, and its axis of rotation is horizontal. The servo motor 22 is mounted on the base 1, and its output shaft is connected to the rotary disk 21 to control the rotary disk 21 to rotate periodically in a certain direction. The reel 23 and the output shaft of the servo motor 22 are on the same straight line. The reel 23 is horizontally mounted at the center of the rotary disk 21 and is used to wind the rolled metal terminals.

[0034] The first guide rail 24 is fixed on the base 1 and located below the reel 23. The first guide rail 24 is used for spreading the metal terminals. Baffles are fixedly connected to both sides of the long side of the first guide rail 24 to limit the metal terminals from falling off. A limiting strip 9 is also installed on the first guide rail 24, with a gap between the limiting strip 9 and the supporting surface of the first guide rail 24. When the metal terminals on the reel 23 are unwound, they pass between the limiting strip 9 and the first guide rail 24, and are then pulled onto the conveying track 4 for transport.

[0035] Initially, the strip-shaped metal terminals are wound around the reel 23 and rest against the rotating disk 21. The servo motor 22 drives the rotating disk 21 to rotate at a specified angle at certain time intervals, thereby driving the reel 23 to rotate and unwinding the metal terminals. After unwinding, the metal terminals pass through the gap between the limiting bar 9 and the first guide rail 24 and extend horizontally onto the conveying track 4 for transport. The metal terminals are continuously transported along the conveying track 4 under the conveying action of the feeding mechanism 5, achieving continuous assembly production as the metal terminals are unwound and transported simultaneously.

[0036] Combination Figure 5 The plastic part feeding mechanism 3 includes a vibratory feeder 31 and a second guide rail 32. The vibratory feeder 31 is mounted on the base 1 and located on one side of the first guide rail 24. The vibratory feeder 31 is used to vibrate and feed the plastic parts, conveying the disordered plastic parts in an orderly manner according to a certain direction. The second guide rail 32 is horizontally set and connected to the output end of the vibratory feeder 31. It has a positioning groove 10 for positioning the plastic parts. The conveying direction of the second guide rail 32 is the same as that of the first guide rail 24. The vibratory feeder 31 is an automated feeding device that can automatically sort, arrange, and orient disordered small plastic parts onto the second guide rail 32 so that the insertion mechanism 6 can push the plastic parts one by one onto the metal terminal.

[0037] The insertion mechanism 6 includes a linear cylinder 61, a push plate 62, and a guide block 63. The guide block 63 is fixed on the base 1 and is located at the end of the second guide rail 32, close to the material conveying track 4. A guide groove 11 is provided on the guide block 63, which communicates with the positioning groove 10. The length direction of the guide groove 11 is perpendicular to the length direction of the positioning groove 10. The push plate 62 is connected to the linear cylinder 61, which controls the push plate 62 to push the plastic part onto the metal terminal. When the plastic parts are oriented and sequentially conveyed onto the second guide rail 32, the linear cylinder 61 controls the push plate 62 to move horizontally. Under the pushing force, the push plate 62 can push a plastic part at the end of the second guide rail 32 along the guide groove 11, causing the plastic part to approach and insert into the metal terminal. The assembly of the plastic part and the metal terminal is achieved by the insertion force.

[0038] The feeding mechanism 5 includes several feeding gears 50. In this embodiment, three feeding gears 50 are provided, but four or five can be provided in other application scenarios. The feeding gears 50 are rotatably connected to the conveying track 4. The teeth of the feeding gears 50 correspond to the through holes of the waste strip. The feeding gears 50 rotate periodically by a stepper motor, and the feeding gears 50 are spaced apart along the conveying direction of the conveying track 4. The conveying track 4 is provided with a clearance groove, which is set along the conveying direction of the conveying track 4 to accommodate the teeth of the feeding gears 50. The existence of the clearance groove can give way to the feeding gears 50 and avoid affecting the rotation of the feeding gears 50. The stepper motor, as the drive source, can control the rotation of the feeding gears 50. Since the teeth of the feeding gears 50 are engaged in the through holes of the waste strip, as the feeding gears 50 rotate, they can generate a horizontal thrust on the waste strip, realizing the synchronous movement of the waste strip and the metal terminal.

[0039] Combination Figure 6 The cutting mechanism 7 includes an upper cutter 71 and a lower cutter 72, which are positioned opposite each other and located on the upper and lower sides of the metal terminal, respectively. The upper cutter 71 is driven by a cylinder to punch the connecting strip between the waste strip and the terminal. The cylinder can drive the upper cutter 71 to move up and down. By controlling the upper cutter 71 to punch the lower cutter 72, the connection between the waste strip and the metal terminal is broken, thus separating the assembled finished product from the waste strip.

[0040] The collection mechanism 8 includes a finished product collection box 81 and a waste collection box 82, both of which are open. The finished product collection box 81 is located below the lower cutter 72 and is used to collect the cut finished products. The waste collection box 82 is located below the end of the conveyor track 4 and is used to receive the waste strip falling from the conveyor track 4. After the waste strip and the metal terminals are cut, the finished metal terminals will fall into the finished product collection box 81 under the action of gravity. As for the waste strip, it will continue to move forward a distance under the action of the feeding mechanism 5, and then the waste strip will gradually fall into the waste collection box 82 under its own gravity.

[0041] In addition, a guide cylinder 12 is installed at the end of the conveying track 4. The guide cylinder 12 is hollow and is used for the cut waste strip to pass through. One end of the guide cylinder 12 faces the end of the conveying track 4, and the other end faces the waste collection box 82. The presence of the guide cylinder 12 can guide the waste strip, making it easier for the waste strip at the end of the conveying track 4 to fall into the waste collection box 82.

[0042] The implementation principle of the assembly equipment for short-circuit caps in this application embodiment is as follows: During production, the terminal feeding mechanism 2 feeds metal terminals. With the cooperation of the conveying track 4 and the feeding mechanism 5, the strip-shaped metal terminals are conveyed along the conveying track 4. At the same time, the plastic part feeding mechanism 3 feeds plastic parts. Under the action of the insertion mechanism 6, the plastic parts are inserted one by one into the metal terminals, completing the assembly operation of the short-circuit cap.

[0043] After assembly, the feeding mechanism 5 continues to transport the metal terminals forward, while the shearing mechanism cuts the assembled metal terminals, separating them from the waste strip. Finally, the collection mechanism 8 collects the waste strip and the finished product separately. The entire assembly process is highly automated, facilitating the assembly of short-circuit caps, improving production efficiency, and reducing the labor intensity of personnel.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
