Description

Technical Field

[0001] This invention belongs to the field of cyclic conveying, and specifically relates to a Bluetooth headset cyclic conveying line. Background Technology

[0002] The production process of Bluetooth headsets includes mold making, injection molding, cable assembly, manufacturing of the microphone or speaker driver unit, PCB assembly, final assembly, quality control testing, and packaging. Among these processes, cable assembly, microphone or speaker driver unit manufacturing, PCB assembly, final assembly, quality control testing, and packaging are all completed on a single assembly line. This assembly line uses a belt conveyor to transport materials between the upper and lower sections. However, due to the different working efficiencies of the upper and lower sections, the lower-efficiency section is prone to material accumulation, especially when employee efficiency decreases or when employees go to the restroom. Furthermore, the belt conveyor can only transport materials from top to bottom, and jig recycling requires manual storage at one end before being centrally sent to the upper section. This necessitates increasing the number of jigs to ensure the normal flow of Bluetooth headset assembly between sections. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a Bluetooth headset circulating conveyor line with a novel structure and convenient and practical design. The conveying mechanism and the return mechanism drive the Bluetooth headset fixture to flow back and forth between the work sections, so as to achieve the purpose of quick fixture recycling and reduce fixture usage.

[0004] A Bluetooth headset circulating conveyor line includes a bracket, a fixture conveying mechanism, and a fixture pre-storage mechanism. The fixture conveying mechanism is mounted on the bracket, and at least one fixture pre-storage mechanism is mounted on the fixture conveying mechanism. The fixture conveying mechanism includes a power unit, a conveying mechanism, a return mechanism, a fixed plate, and a power transmission shaft.

[0005] Furthermore, both the conveying mechanism and the return mechanism include sprockets, a track plate, a chain, a fixture adsorption and conveying device, and a one-way bearing. The track plate has an annular groove on its side wall, and annular limiting inner rails are respectively provided on the upper and lower sides of the annular groove. Outer stabilizing rails are respectively provided on both sides of the annular limiting inner rails. Several sprocket holes are penetrating the track plate. Several sprockets are connected to corresponding power transmission shafts through one-way bearings. The sprockets are disposed in the sprocket holes. Several sprockets are connected by chain drive. The chain is disposed between the annular limiting inner rail and the bottom of the annular groove. Several fixture adsorption and conveying devices are evenly connected to the chain and disposed between the annular limiting inner rail and the outer stabilizing rail. The fixture adsorption and conveying devices are tumblingly connected to the annular limiting inner rail and the outer stabilizing rail.

[0006] Furthermore, the fixture adsorption conveying device includes connecting strips, stabilizing track bearings, rotating shafts, and conveying plates. Two rotating shafts are symmetrically connected to one side of the conveying plate, and two stabilizing track bearings are respectively connected to both ends of the rotating shafts. One end of each of the two connecting strips is movably connected to the rotating shaft, and the other end is respectively connected to the upper and lower sides of the chain. The conveying plate has several magnet holes for installing magnets.

[0007] Furthermore, the fixture pre-storage mechanism includes a fixture fixing plate, an adjusting plate, a stabilizing plate, a fixture positioning device, a lifting cylinder, a positioning slide bar, and an adjusting column. The two ends of the fixture fixing plate are respectively connected to the conveying mechanism and the return mechanism. The adjusting plate and the stabilizing plate are symmetrically connected to one side of the fixture fixing plate. The adjusting plate and the stabilizing plate are each provided with several sets of stepped holes arranged in a straight line to install the fixture positioning device. At least one of the lifting cylinders is installed on the worktable between the adjusting plate and the stabilizing plate. The piston rod of the lifting cylinder passes through the worktable. The lower end of the stabilizing plate is provided with at least one slide groove. The slide groove is provided with a limiting waist-shaped hole and a magnet groove for installing magnets. The positioning slide bar is set in the slide groove. One end of the adjusting column passes through the limiting waist-shaped hole and is connected to the positioning slide bar.

[0008] Furthermore, the fixture positioning device includes a sealing nut, a spring, a push plate, and a positioning ramp. The adjusting plate and the stabilizing plate have stepped holes. The sealing nut, spring, and push plate are disposed in the stepped holes. The spring is disposed between the sealing nut and the push plate.

[0013] (1) The Bluetooth headset circulating conveyor line of the present invention has a novel structure and is convenient and practical. The Bluetooth headset fixture is driven to flow back and forth between the work sections by the conveying mechanism and the return mechanism, so as to achieve the purpose of quick fixture recycling and reduce fixture investment.

[0014] (2) The Bluetooth headset circulating conveyor line of the present invention conveys the fixture adsorption conveyor through the chain, which reduces the number of belt conveyors used and avoids the need to replace or adjust the conveyor belt at regular intervals, improves the equipment operation cycle and stability, and reduces the number of motors. The working line within 50 meters only needs one motor to meet the transmission requirements, thereby reducing the failure rate of the transmission line, improving stability, and reducing power consumption, equipment maintenance costs and time.

[0015] (3) The Bluetooth headset circulating conveyor line of the present invention uses a fixture pre-storage mechanism to store fixtures, thereby avoiding the situation where the fixtures flow too quickly and cause employees to panic and make mistakes. At the same time, it avoids the situation where unprocessed Bluetooth headsets flow into the next section due to reduced work efficiency when employees change jobs, and effectively ensures the effect of rest and adjustment of work positions for assembly line personnel.

Detailed Implementation

[0017] The embodiments of the present invention will be further described below with reference to the accompanying drawings. Example

[0018] like Figure 1 As shown; a Bluetooth headset circulating conveyor line includes a bracket 1, a fixture conveying mechanism 2, and a fixture pre-storage mechanism 3. The fixture conveying mechanism 2 is mounted on the bracket 1, and at least one fixture pre-storage mechanism 3 is mounted on the fixture conveying mechanism 2. The fixture conveying mechanism 2 includes a power unit 6, a conveying mechanism 7, a return mechanism 8, a fixed plate 9, and a power transmission shaft 10. Several power transmission shafts 10 are connected between two fixed plates 9 and are drive-connected to the conveying mechanism 7 and the return mechanism 8. The conveying mechanism 7 and the return mechanism 8 are respectively connected to corresponding fixed plates 9. The power unit 6 is connected to the fixed plate 9 and is drive-connected to one of the power transmission shafts 10. Several stabilizing frames are connected between the conveying mechanism 7 and the return mechanism 8. A worktable 4 and a conveying table 5 are respectively connected to both sides of the conveying mechanism 7 and the return mechanism 8.

[0019] In this system, employees sit on both sides of the circulating conveyor line. One side of the fixture is equipped with an iron plate or tinplate for adhering to the conveying mechanism 7 and the return mechanism 8, which facilitates the transport of the fixture. The bottom of the fixture is rounded to ensure that the fixture is not obstructed by the height difference between adjacent conveyor platforms 5 during transport. Multiple circulating conveyor lines are connected according to the length of the production line, and the chains of the circulating conveyor lines must be connected. At the same time, the chains of the circulating conveyor lines can also be unconnected, but employees need to work between adjacent circulating conveyor lines so that after the processing of this section is completed, the fixture can be placed into the next circulating conveyor line. The installation method is selected according to the structure of the production line.

[0020] Specifically, after completing their work in a specific process segment, employees push the fixture onto the conveyor mechanism 7, which then moves the fixture to the next process segment. When the fixture is returned, employees place it on the conveyor platform 5 and return it via the return mechanism 8. The power unit 6 drives the power transmission shaft 10 to rotate, which in turn drives the conveyor mechanism 7 and the return mechanism 8. The number of power units 6 can be set according to the situation. If separate transmission is required, two power units 6 are needed to drive the conveyor mechanism 7 and the return mechanism 8 respectively. If the production line is short, one power unit 6 can be used for intermittent transmission, driving the conveyor mechanism 7 and the return mechanism 8 respectively.

[0021] In another embodiment of the present invention, both the conveying mechanism 7 and the return mechanism 8 include sprockets 71, track plates 72, chains 73, fixture adsorption and conveying devices 74, and one-way bearings. An annular groove 710 is formed on the side wall of the track plate 72. Annular inner limiting rails 711 are respectively provided on the upper and lower sides of the annular groove 710, and outer stabilizing rails 712 are respectively provided on both sides of the annular inner limiting rails 711. A plurality of sprocket holes 713 penetrate the track plate 72, and the plurality of sprockets 71 are connected by one-way... The bearing is connected to the corresponding power transmission shaft 10. The sprocket 71 is set in the sprocket hole 713. Several sprockets 71 are connected by a chain 73. The chain 73 is set between the inner annular limiting rail 711 and the bottom of the annular groove 710. Several fixture adsorption and conveying devices 74 are evenly connected to the chain 73 and set between the inner annular limiting rail 711 and the outer stabilizing rail 712. The fixture adsorption and conveying devices 74 are rolledly connected to the inner annular limiting rail 711 and the outer stabilizing rail 712.

[0022] Specifically, the forward rotation of the power transmission shaft 10 drives the one-way bearing to rotate, causing the sprocket 71 of the conveying mechanism 7 to rotate, while the one-way bearing of the return mechanism 8 does not provide power transmission. The sprocket 71 drives the chain 73 to move, and the chain 73 drives the fixture adsorption conveying device 74 and the fixture adsorbed on it to move. The fixture adsorption conveying device 74 moves stably between the annular inner limit rail 711 and the outer stabilizing rail 712. Conversely, the reverse rotation of the power transmission shaft 10 drives the one-way bearing to rotate, causing the sprocket 71 of the return mechanism 8 to rotate, while the one-way bearing of the conveying mechanism 7 does not provide power transmission.

[0023] In another embodiment of the present invention, the fixture adsorption conveying device 74 includes connecting bars 75, stabilizing track bearings 76, rotating shafts 77 and conveying plates 78. Two rotating shafts 77 are symmetrically connected to one side of the conveying plate 78, two stabilizing track bearings 76 are respectively connected to both ends of the rotating shafts 77, one end of the two connecting bars 75 is movably connected to the rotating shafts 77 and the other end is respectively connected to the upper and lower sides of the chain 73, and the conveying plate 78 is provided with a plurality of magnet holes 79 for installing magnets.

[0024] Specifically, chain 73 drives connecting bar 75 to move, connecting bar 75 drives rotating shaft 77 to move, and stabilizing track bearing 76 rolls between annular inner limit rail 711 and outer stabilizing rail 712 to ensure the stability of conveyor plate 78 during movement. Iron plates or tinplate sheets on the fixture are attracted by magnets. Conveyor plate 78 is preferably set in annular groove 710 and its surface is flush with the side of track plate 72 to ensure that the conveyor plate 78 will not injure the hands of employees during movement and cause work-related injuries. The distance between adjacent conveyor plates 78 is preferably controlled within 2mm to avoid fingers or nails getting stuck.

[0025] In another embodiment of the present invention, the fixture pre-storage mechanism 3 includes a fixture fixing plate 31, an adjusting plate 32, a stabilizing plate 33, a fixture positioning device 36, a lifting cylinder 37, a positioning slide bar 39, and an adjusting column 310. The two ends of the fixture fixing plate 31 are respectively connected to the conveying mechanism 7 and the return mechanism 8. The adjusting plate 32 and the stabilizing plate 33 are symmetrically connected to one side of the fixture fixing plate 31. The adjusting plate 32 and the stabilizing plate 33 are each provided with a plurality of stepped holes arranged in a straight line for installing the fixture positioning device 36. At least three lifting cylinders 37 are installed on the worktable plate 4 between the adjusting plate 32 and the stabilizing plate 33. The piston rod of the lifting cylinder 37 passes through the worktable plate 4. The lower end of the stabilizing plate 33 is provided with at least one slide groove 38. The slide groove 38 is provided with a limiting waist-shaped hole and a magnet groove 311 for installing magnets. The positioning slide bar 39 is disposed in the slide groove 38. One end of the adjusting column 310 passes through the limiting waist-shaped hole and is connected to the positioning slide bar 39.

[0026] Specifically, the employee adjusts the adjusting column 310 to lower or raise the positioning slide bar 39 and uses a magnet to hold the positioning slide bar 39 in place, preventing it from shifting downwards and ensuring it is positioned at the designated location. After lowering, the positioning slide bar 39 blocks the fixture being conveyed by the conveying mechanism 7. The fixture is then lifted by the lifting cylinder 37, allowing it to enter between the adjusting plate 32 and the stabilizing plate 33. The fixture is then positioned by the fixture positioning device 36 to achieve the purpose of gradual lifting. The fixture positioning devices 36 on the adjusting plate 32 and the stabilizing plate 33 are symmetrically arranged to provide stable support for both ends of the fixture. At least two fixture positioning devices 36 form a group, each supporting one side of the fixture positioning device 36.

[0027] In another embodiment of the present invention, the fixture positioning device 36 includes a sealing nut 312, a spring 313, a push plate 314, and a positioning ramp 315. The adjusting plate 32 and the stabilizing plate 33 have stepped holes. The sealing nut 312, the spring 313, and the push plate 314 are disposed in the stepped holes. The spring 313 is disposed between the sealing nut 312 and the push plate 314. The positioning ramp 315 is connected to the push plate 314 and passes through one end of the stepped hole.

[0028] Specifically, spring 313 ensures that the positioning ramps 315 have telescopic function, so that when the fixture rises, it contacts and squeezes the positioning ramps 315, causing the positioning ramps 315 to enter the step hole. After the fixture moves above the positioning ramps 315, spring 313 pushes push plate 314 to make the positioning ramps 315 extend out of the step hole to support the fixture. A groove needs to be opened at the bottom of both ends of the fixture for the positioning ramps 315 to extend into, so that when the fixture is lifted by the fixture below, adjacent ones pass by and the positioning ramps 315 cannot be inserted between the two fixtures.

[0029] In another embodiment of the present invention, the upper end of the stabilizing plate 33 is connected to the storage platform 35, and the upper end of the adjusting plate 32 is connected to a plurality of pushing cylinders 34; including adjusting bolts, the fixture fixing plate 31 is provided with a plurality of waist-shaped countersunk holes, one end of the adjusting bolts passes through the fixture fixing plate 31 and is connected to the adjusting plate 32; wear-resistant pads are laid on the worktable plate 4 and the conveying plate 5; including a foot valve, the foot valve is connected to the lifting cylinder 37.

[0030] Specifically, the jig is pushed up to be flush with the storage platform 35 by the push cylinder 34, and then pushed onto the storage platform 35 to increase the number of jigs that can be stored. The position can be adjusted according to the length of the jig by connecting the adjusting bolt through the countersunk hole. Wear-resistant pads are provided to prevent the jig from rubbing against the worktable 4 and the conveyor platform 5 for a long time, which would require replacement and increase the cost. However, the cost of replacing the wear-resistant pads is low. The lifting cylinder 37 is opened by the foot valve to reduce the use of induction sensors. The jig can be lifted by the employees according to the work situation, which is especially convenient when multiple people are working in the same position.

For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, all equivalent changes and modifications made without departing from the spirit and scope of the present invention are covered within the scope of the present invention.
