Description

Technical Field

[0001] This application relates to the field of mechanical assembly, and in particular to an automatic assembly machine for action camera connectors. Background Technology

[0002] Action camera connectors are fundamental components used to enable data transmission and external accessory expansion. Their structure typically consists of a base, a ring, and conductive pins, among other tiny nested parts. The manufacturing process for action camera connectors usually involves multiple complex steps, including tape feeding, pin insertion, component clamping and curing, and final cutting and unloading. Due to the small size of the various components and the high precision requirements of assembly, efficiently performing the precision assembly of these multiple parts is a crucial aspect of manufacturing such precision connectors.

[0003] Currently, the industry mostly uses a step-by-step manufacturing process for assembling action camera connectors. In traditional assembly lines, the feeding of components, the pre-positioning of pins, the pressing of structures, and the subsequent cutting and transfer of finished products often rely on multiple relatively independent single machines. The semi-finished connectors need to be frequently transferred between different process stations through external auxiliary handling mechanisms, or rely on manual labor for secondary transfer and positioning of loose parts.

[0004] The aforementioned technologies suffer from drawbacks such as multiple disconnected processes leading to poor assembly continuity and low levels of automation integration. In traditional discrete processing, frequent transfers and handling can cause semi-finished products to shift position, resulting in uneven pressure during subsequent pressing or damage to components. Furthermore, the lack of internal rhythm coordination among the individual pin pre-positioning, cutting, and material transfer stages prevents precise locking and pressing, as well as smooth and continuous material separation and discharge, all achieved through intermittent conveyor belt transport on the same production line. This ultimately limits the overall precision assembly efficiency. Summary of the Invention

[0005] To overcome the shortcomings of the prior art, this application provides an automatic assembly machine for action camera connectors, which can realize the automated assembly of action camera connectors, improve assembly efficiency and accuracy, and ensure the consistency of connector quality.

[0006] This application is achieved through the following technical solution: An automatic assembly machine for action camera connectors includes: a feeding and conveying device for providing a material strip and intermittently conveying the material strip along a conveying direction, the material strip carrying an assembly, the assembly including a base and a ring initially fitted onto the base; the feeding and conveying device having a first station, a second station, and a third station sequentially arranged along the conveying direction; a pin feeding device for providing pins and pre-positioning the pins within the base of the assembly at the first station; and a pressing device disposed at the second station, the pressing device including a positioning component and a pressing component; the positioning component for locking the material strip at the second station; and the pressing component for pressing the pins and the assembly after the material strip is locked. A ring body is used to press the pin into the base and press the ring body tightly against the base to form a connector; a cutting device is provided at the third station to separate the connector from the material strip; a transfer device includes a conveying component and a transfer component; the conveying component is used to pick up the connector separated by the cutting device and transport the connector to the receiving position of the transfer component; the transfer component is used to drive the connector to transfer between the receiving position and the transfer position, and the transfer component is provided with a clamping component for clamping the connector during the transfer; a discharge device is used to pick up the connector located at the transfer position and move the connector to the next process.

[0007] By adopting the above technical solution, the feeding and conveying device, the pin feeding device, the pressing device, the cutting device, the transfer device, and the discharging device are integrated into the same equipment to achieve fully automated assembly line. At the pressing station, the positioning component locks the material strip in advance, which effectively avoids the assembly deviation caused by the misalignment of the pin and the base during the pressing process. At the same time, the transfer device uses the clamping component to apply a stable constraint to the connector during the movement, preventing the connector in the free state from positional displacement or falling off, thereby improving the dimensional accuracy and yield of the assembled product.

[0008] Furthermore, the pin feeding device includes a vibrating feeding plate and a pin conveying mechanism; the pin conveying mechanism is used to pick up a single pin from the end of the material channel of the vibrating feeding plate and transfer the picked-up pin to the base of the assembly at the first station. The pin transport mechanism includes a suction seat and a drive assembly for moving the suction seat. The suction seat is provided with a suction tube and a pressure head. The suction tube is connected to the suction seat through a first elastic element. The suction tube and the pressure head are spaced apart along the conveying direction, and the distance between the suction tube and the pressure head is the same as the distance between two adjacent assemblies on the conveyor belt. The drive assembly is used to drive the suction seat to reciprocate between a pick-up position and a release position. When in the pick-up position, the suction tube is aligned with the end of the feed channel and picks up a single pin. When in the release position, the suction tube is aligned with the current base on the conveyor belt, and the pressure head is aligned with the adjacent base on the conveyor belt located downstream of the current base along the conveying direction. The suction tube releases the picked-up pin into the current base, while the pressure head initially presses the pin that has been pre-placed in the adjacent base.

[0009] By adopting the above technical solution, the suction seat in the pin feeding device is equipped with both a suction pipe and a pressure head, and the distance between the two is consistent with the distance between two adjacent assemblies on the conveyor belt. When the drive assembly drives the suction seat to move between the picking position and the discharging position, the suction pipe releases the adsorbed pins into the current base, while the pressure head initially presses the pins that have been pre-placed in the adjacent base. This allows the pin pre-placement and initial pressing actions to be completed simultaneously in one discharging motion, avoiding the need for additional pre-pressing stations or actions, simplifying the feeding process and shortening the cycle time. In addition, the suction pipe is connected to the suction seat through a first elastic element, which acts as a buffer when releasing the pins, preventing rigid collisions between the suction pipe and the base that could damage the pins or the base, thus ensuring the reliability of the pre-placement process. This technical solution achieves simultaneous pin movement and release and initial pressing of pins at adjacent stations through the combined actions of a single conveying mechanism, realizing functional integration.

[0010] Furthermore, the pressing assembly includes an upper pressing part and a lower pressing part; the upper pressing part includes an upper pressing plate and an upper pressing drive for driving the upper pressing plate to move up and down; the lower pressing part is located below the material strip and is used to press the base of the assembly upward; the positioning assembly includes multiple positioning pins located at the bottom of the upper pressing plate, the positioning pins being used to insert into positioning holes opened on the material strip; the bottom of the upper pressing plate is also provided with an upper pressing rod, and a pressure ring is sleeved on the outer side of the upper pressing rod; the bottom extension height of the multiple positioning pins is lower than the bottom height of the upper pressing rod and the pressure ring, so that when the upper pressing drive drives the upper pressing plate to descend, the multiple positioning pins insert into the positioning holes before the upper pressing rod and the pressure ring to lock the material strip; as the upper pressing plate continues to descend, the bottom end of the upper pressing rod and the bottom end of the pressure ring synchronously press against the top of the insert pin and the top of the ring body, respectively.

[0011] By adopting the above technical solution, the positioning component of the pressing device uses multiple positioning pins located at the bottom of the upper pressure plate. By limiting the height of the bottom of the positioning pins, when the upper pressure drive drives the upper pressure plate to descend, the multiple positioning pins insert into the positioning holes of the material strip before the upper pressure rod and the pressure ring to lock the material strip. Subsequently, the upper pressure rod and the pressure ring synchronously press against the top of the insert pin and the top of the ring body, realizing the timing control of positioning and locking before pressing. This avoids the pressing position deviation caused by the material strip shifting during the pressing process and ensures the positional accuracy of the insert pin pressing into the base and the ring body clamping base. At the same time, the upper pressure rod and the pressure ring apply pressure synchronously, so that the two actions of inserting the insert pin and clamping the ring body are completed in the same pressing stroke, improving the pressing efficiency.

[0012] Furthermore, the pressing part includes a bottom pressing block, a support block, and a lower driving member for driving the bottom pressing block to move up and down; the support block is disposed below the material strip at the second work station, and the support block has a guide groove adapted to the bottom pressing block in the vertical direction, and the bottom pressing block is slidably disposed in the guide groove; a clearance groove is provided at the top center of the bottom pressing block, and when the bottom pressing block presses upward against the base of the assembly, the portion of the pin extending downward from the base is suspended and accommodated in the clearance groove.

[0013] By adopting the above technical solution, the bottom pressure block of the lower pressing part is slidably set in the guide groove of the support block and driven to move up and down by the lower driving component. When the bottom pressure block presses against the base of the assembly upward, the support block plays a guiding and limiting role for the bottom pressure block, ensuring the straightness and stability of the rising path of the bottom pressure block, thereby providing reliable lower support for pressing. The clearance groove opened in the center of the top of the bottom pressure block allows the part of the pin that extends downward from the base to be suspended and accommodated in the clearance groove, avoiding the bottom pressure block from directly contacting and squeezing the tail of the pin, which would damage the pin or cause the pin to be deformed by force. At the same time, by suspending the tail of the pin and using the bottom pressure block to abut against the bottom plane of the base, the pressing reaction force is evenly distributed on the base body, ensuring the positional accuracy and posture stability of the pin in the base during the pressing process.

[0014] Furthermore, the cutting device includes an upper die assembly located above the strip and a lower die assembly located below the strip; the upper die assembly includes an upper die base and an upper die drive member that drives the upper die base to press down and lock the strip, the upper die base is provided with a through-hole, the through-hole corresponding to the connector at the third station; the lower die assembly includes a lower die base, a punch, and a lower die drive member that drives the lower die base to rise; when the upper die base presses down to fix the strip, the lower die drive member drives the lower die base and the punch to rise, so that the punch presses upward to separate the connector from the strip, and pushes the separated connector into the through-hole for the conveying component to pick up.

[0015] By adopting the above technical solution, the upper die assembly provides a stable pressure constraint downwards, and the lower die punch applies a punching force from bottom to top, which can smoothly separate the connector from the strip body. After separation, the connector is pushed into the material picking hole of the upper die base for limited storage, avoiding uncontrolled bouncing of the connector at the moment of separation, and providing a fixed target coordinate for the accurate picking of subsequent handling components.

[0016] Furthermore, the conveying assembly includes a mounting bracket; the mounting bracket is provided with a horizontally extending first guide rail, a first driving member, and a first slider slidably connected to the first guide rail, the first driving member being used to drive the first slider to move horizontally along the first guide rail; the first slider is provided with a vertically extending second guide rail, a second driving member, and a second slider slidably connected to the second guide rail, the second driving member being used to drive the second slider to move vertically along the second guide rail; a conveying head is movably disposed on the second slider in the vertical direction, a second elastic member is provided between the conveying head and the second slider, the conveying head being able to elastically float relative to the second slider in the vertical direction through the second elastic member.

[0017] By adopting the above technical solution, the first driving component of the conveying assembly drives the first slider to move horizontally along the first guide rail, and the second driving component drives the second slider to move vertically along the second guide rail, thereby realizing flexible positioning of the conveying head in both horizontal and vertical directions. The second elastic component set between the conveying head and the second slider allows the conveying head to float elastically relative to the second slider in the vertical direction. When the conveying head contacts and picks up the connector, the elastic floating can absorb the excessive stroke during the descent of the conveying head, avoiding rigid impact between the conveying head and the connector or the picking hole, which would damage the connector. At the same time, it ensures stable contact pressure between the conveying head and the connector, improving the reliability and consistency of picking.

[0018] Furthermore, the transfer assembly includes a transfer guide rail, a transfer drive, and a transfer seat slidably fitted on the transfer guide rail. The transfer drive is used to drive the transfer seat to translate between the receiving position and the turning-out position. The transfer seat has a receiving groove for accommodating the connector, and positioning blocks are provided on both sides of the receiving groove. The inner contour of the positioning blocks is adapted to the shape of the connector's base. The clamping assembly includes a clamping drive, a drive wedge, and two clamping sliders slidably disposed on both sides of the transfer seat. The drive wedge and the two clamping sliders are respectively engaged by a wedge surface, and each clamping slider abuts against the transfer seat with a return spring. When the clamping drive drives the drive wedge to move, the drive wedge squeezes the two clamping sliders against the elastic force of the return spring and slides towards each other to clamp the connector. When the drive wedge retracts, the two clamping sliders slide away from each other under the elastic force of the return spring to release the connector.

[0019] By adopting the above technical solution, positioning blocks with inner contours that match the shape of the connector base are provided on both sides of the receiving groove of the transfer base. When the connector is placed in the receiving groove by the transfer component, the positioning blocks play a role in pre-positioning and limiting the connector, so that the connector maintains the correct posture in the receiving groove. The driving wedge of the clamping component and the two clamping sliders cooperate through the wedge surface. When the clamping drive drives the driving wedge to move, the two clamping sliders slide towards each other under the action of the wedge surface to overcome the elastic force of the return spring to clamp the connector. When the driving wedge retracts, the two clamping sliders slide away from each other under the action of the return spring to release the connector. This achieves precise control of clamping and releasing, ensuring that the connector remains stable during the transfer process between the receiving position and the transfer position, and preventing the connector from being displaced or falling off during the transfer process.

[0020] Furthermore, it also includes a cap body feeding mechanism, a cap body cutting mechanism, a cap body conveying mechanism, and a cap body pressing mechanism; the cap body feeding mechanism is used to provide cap body material strips; the cap body cutting mechanism is used to punch the cap body material strips to separate individual cap bodies; the cap body conveying mechanism is used to pick up the individual cap bodies and place the individual cap bodies on top of the connector located at the turnout position; the cap body pressing mechanism includes a pressing head and a pressing drive assembly for driving the pressing head to move horizontally and vertically; when the connector is located at the turnout position and the material transfer assembly clamps the connector, the cap body pressing mechanism drives the pressing head to press the cap body downwards before the material discharge device picks up the connector, so as to press the cap body onto the connector; after the pressing is completed, the pressing head retracts to avoid the material discharge device picking up the connector.

[0021] By adopting the above technical solution, the cap feeding mechanism provides cap material strips, the cap cutting mechanism punches the cap material strips to separate individual caps, the cap transport mechanism places the individual caps on top of the connector located at the turnout position, and the cap pressing mechanism drives the pressing head downward to press the cap onto the connector while the material transfer component clamps the connector. After pressing is completed, the pressing head retracts to avoid being picked up by the discharge device. This integrates the cap pressing process into the gap when the connector is waiting for discharge at the turnout position, making full use of the waiting time at the turnout position. There is no need to set up an additional independent cap pressing station or extend the cycle time of the whole machine, thus achieving a high degree of integration of functional modules.

[0022] Furthermore, the discharge device includes a first inspection station, a second inspection station, a discharge station, and a moving component; the first inspection station is equipped with a first inspection frame, and the second inspection station is equipped with a second inspection frame; the moving component includes a mounting base, on which a third guide rail, a third driving member, and a third slider slidably connected to the third guide rail are provided along the horizontal direction, the third driving member being used to drive the third slider to move horizontally; the third slider is equipped with a fourth guide rail, a fourth driving member, and a slide block slidably connected to the fourth guide rail along the vertical direction, the fourth driving member being used to drive the slide block to rise and fall; the slide block is equipped with a mounting plate parallel to the third guide rail, and so on. The mounting plate is provided with a first picking head, a second picking head, and a third picking head arranged sequentially at intervals along the horizontal direction, with equal horizontal spacing between any two adjacent picking heads; the first picking head is used to pick up the connector from the turn-out position and transfer it to the first inspection frame; the second picking head is used to pick up the connector from the first inspection frame and transfer it to the second inspection frame; the third picking head is used to pick up the connector from the second inspection frame and transfer it to the unloading station for removal; the turn-out position, the first inspection frame, the second inspection frame, and the unloading station are arranged sequentially at equal intervals along the horizontal direction, and the horizontal spacing between adjacent stations is equal to the horizontal spacing between each picking head.

[0023] By adopting the above technical solution, the horizontal distribution distance between the three inspection and unloading stations and the three picking heads is set to the same value, so that the three picking heads can perform one cycle of translation and lifting under the drive of the same third drive component. This allows the simultaneous transfer of three batches of connectors across stations from the turnout position to the first inspection frame, from the first inspection frame to the second inspection frame, and from the second inspection frame to the unloading station. The equidistant array axial arrangement improves the material flow efficiency.

[0024] Furthermore, a rotary drive is connected to the second pick-up head; the rotary drive is used to drive the second pick-up head to rotate the connector around the vertical axis by a preset angle during the process of the second pick-up head transporting the connector, so as to change the detection posture of the connector on the second detection frame.

[0025] By adopting the above technical solution, a rotary drive module is superimposed on the spatial transport trajectory of the second picking head, so that the connector can synchronously complete the required angle of flipping posture change during the idle time of crossing the inspection station. This reduces the need to add a rotary positioner to the inspection station body and meets the all-round inspection requirements of the connector's multi-faceted appearance features in a direct and effective way.

[0026] In summary, this application includes at least one of the following beneficial technical effects: This application prevents pin damage and displacement and connector drop by pre-positioning and locking constraints at the press-fitting station and simultaneously applying automatic centering clamping during the transfer process, thereby improving assembly accuracy and flow stability. This application utilizes an equidistantly arranged suction and pressure double-head linkage and an upper and lower clamping pressing mechanism with clearance grooves to achieve stable assembly of components without damaging fragile pins and flexible strips. This application utilizes a multi-station and multi-feed head system arranged in an equidistant array to work together, enabling the synchronous cross-station transfer of multiple batches of connectors with a single drive, thereby improving the automation efficiency of subsequent inspection and unloading processes.

The first picking head 8171 is used to transfer the connector 2 from the exit position to the first inspection frame 82; the second picking head 8172 is used to transfer the connector 2 from the first inspection frame 82 to the second inspection frame 83; and the third picking head 8173 is used to transfer the connector 2 from the second inspection frame 83 to the packaging and unloading station for packaging by the packaging machine. The second feeding head 8172 is connected to a rotary drive 8174, which can be a rotary cylinder. When the mounting plate moves toward the first inspection station, the rotary drive 8174 drives the second feeding head 8172 to rotate 90 degrees clockwise, and when the mounting plate moves toward the second inspection station, the rotary drive 8174 drives the second feeding head 8172 to rotate 90 degrees counterclockwise.

[0036] refer to Figures 12 to 13The equipment also includes a cap feeding mechanism 7, a cap cutting mechanism 71, a cap conveying mechanism 72, and a cap pressing mechanism 73, which can selectively install caps 24 on the connector 2 according to production requirements. The cap feeding mechanism 7 includes a cap feeding rack and a conveyor belt. The cap feeding rack is used to carry the cap material strip wound into a coil. The conveyor belt is arranged between the cap feeding rack and the cap cutting mechanism 71 to guide the cap material strip to tension and transport it along a predetermined path to the cap cutting mechanism 71. The cap cutting mechanism 71 includes an upper cutting die, a lower cutting die, and a cutting drive. The lower cutting die is fixedly mounted on the frame, and the upper cutting die is located directly above the lower cutting die. The cutting drive drives the upper cutting die to rise and fall relative to the lower cutting die. The cap material strip passes between the upper and lower cutting dies. When the upper cutting die descends, it cooperates with the lower cutting die to punch the cap material strip, thereby separating individual caps 24. The cap transport mechanism 72 includes a transport suction head and a transport drive assembly. The transport suction head is connected to a vacuum generator for picking up individual caps 24 separated by the cap cutting mechanism 71 using negative pressure suction. The transport drive assembly includes a horizontal drive and a vertical drive for driving the transport suction head to reciprocate between the cap cutting mechanism 71 and the exit position, placing the individual caps 24 on top of the connector 2 located at the exit position. The cap pressing mechanism 73 includes a pressing head 731 and a pressing drive assembly 732. The pressing drive assembly 732 includes a horizontal drive and a vertical drive; the horizontal drive drives the pressing head 731 to move horizontally to align with the connector 2, and the vertical drive drives the pressing head 731 to move vertically. When connector 2 is in the out position and the transfer assembly 62 clamps connector 2, the press-in drive assembly 732 drives the press-in head 731 to press down on the cap 24 and press the cap 24 onto connector 2; after pressing is completed, the press-in head 731 retracts to avoid the discharge device 8 picking up connector 2.

[0037] The implementation principle of this embodiment is as follows: The feeding and conveying device 1 intermittently conveys the material belt 25 carrying the assembly along the conveying direction. When the material belt 25 reaches the first station, the pin conveying mechanism 32 of the pin feeding device 3 picks up a single pin 23 from the vibrating feeding plate 31 and releases it into the current base 21 through the suction pipe 323. At the same time, the pressure head 324 initially presses the pin 23 in the downstream adjacent base 21. The material belt 25 advances to the second station, and the positioning component 41 of the pressing device 4 inserts the positioning pin 411 into the positioning hole 26 of the material belt 25 to lock the material belt 25. The upper pressure rod 423 and the pressure ring 424 of the pressing component 42 simultaneously press the top of the pin 23 and the top of the ring 22, and the lower pressure part presses the base 21 upward. With the cooperation of the upper and lower parts, the pin 23 is pressed into the base 21 and the ring 22 is pressed tightly to form the connector 2. The strip 25 enters the third station. The upper die assembly 51 of the cutting device 5 locks the strip 25, and the punch 522 of the lower die assembly 52 pushes the connector 2 upward, separating it from the strip 25 and inserting it into the picking hole 513. The transport assembly 61 of the transfer device 6 picks up the connector 2 from the picking hole 513, transports it to the receiving position of the transfer assembly 62 and places it into the receiving groove 624. The clamping assembly 63 clamps the connector 2, and the transfer assembly 62 moves it horizontally to the exit position. Subsequently, the cap feeding mechanism 7, the cap cutting mechanism 71, the cap transport mechanism 72 and the cap pressing mechanism 73 work together to place a single cap 24 on top of the connector 2 and press it into place. The pressing head 731 retracts to avoid obstruction. Finally, the moving component 81 of the unloading device 8 drives the three picking heads to sequentially pick up connector 2 from the turn-out position, the first inspection station, and the second inspection station, and transfer it to the next station for inspection. Finally, the third picking head 8173 transfers it to the unloading station for output, completing the finished product output. Throughout the process, the actions of each station are coordinated, realizing automated continuous assembly.
