DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0024] Embodiment: In the prior art, the double-station conveying device generally adopts independent width adjustment, which cannot realize the synchronous width adjustment of multiple tracks, cannot realize the convenient replacement of products, and is not suitable for the double-station operation of the same product. Even if a double-station conveying device is used to transport ceramic light sources, the same power is generally used to control multiple tracks to start or stop at the same time, which cannot adapt to the independent operation of the double stations of the same product. In addition, the track width of the double-station conveying device in the prior art is not provided with an adjustment component. If there are processing and installation errors in the device before leaving the factory, it will be difficult to adjust the spacing between different tracks to be consistent, which is not convenient for conveying the same product. In addition to the problems existing in the device, the size of the ceramic light source itself is small, and the structure of the conveying device is a narrow and long structure. There is a practical need for width adjustment, which makes it impossible to install a motor in the space between the tracks, and thus the motor cannot be directly connected to the active pulley of the track on the active side. At the same time, the narrow and long structure setting will cause uneven track spacing, making the spacing at both ends of the track different. Therefore, a double-station synchronous width adjustment conveying device for ceramic light sources in this embodiment, such as Figure 1 As shown, the ceramic light source dual-station synchronous width adjustment conveying device includes station A and station B. Its structure includes: station A power transmission assembly, station B power transmission assembly, station A fixed side track 48, station A movable side track 47, station B fixed side track 46, station B movable side track 45, and helical gear linkage width adjustment assembly. The station A power transmission assembly provides power for station A conveying, and the station B power transmission assembly provides power for station B conveying. The two are symmetrical on the left and right, and both can be used as supports for the entire conveying device.

The screw locking nut 25 locks the screw 12 to prevent the screw 12 from axially shaking and ensure that the freedom of rotation of the screw 12 is not restricted.

[0026] The lead screw 12 and two lead screw nuts 10 form a lead screw assembly, so that the lead screw 12 can be rotated to drive the lead screw nut 10 to move forward and backward in a straight line. The bevel gear 27 is installed at the head of the lead screw 12 and is locked with a top screw so that the bevel gear 27 drives the lead screw 12 when it rotates. There are two A-station moving plates 9, which are used to support the A-station and the B-station. They are fixed on the slider 14 through the connecting plate 11. The linear guide composed of the slide rail 13 and the slider 14 is installed on the A-station bottom plate 5, so that the A-station moving plate 9 can be translated along the slide rail 13. Among them, the A-station moving plate 9 of the A-station is installed between the A-station active shaft middle plate 16 and the A-station active shaft front plate 21 through the lead screw nut 10 and the lead screw 12, so that the lead screw 12 can be rotated to drive the A-station moving plate 9 of the A-station to translate between the A-station active shaft middle plate 16 and the A-station active shaft front plate 21 through the lead screw nut 10.

[0027] The A-station moving plate 9 of the B-station is installed between the A-station driving shaft middle plate 16 and the A-station driving shaft rear plate 4 through the screw nut 10 and the screw 12, so that the screw 12 can rotate and drive the A-station moving plate 9 of the B-station to translate between the A-station driving shaft middle plate 16 and the A-station driving shaft rear plate 4 through the screw nut 10. The motor 1 is installed on the A-station driving shaft rear plate 4 through the motor connecting seat 2. The spline shaft 15 is installed between the A-station driving shaft front plate 21 and the A-station driving shaft rear plate 4 through the power bearing 6 and the driving shaft bearing 23. The spline shaft 15 is connected to the main shaft of the motor 1 through the coupling 3, so that the motor 1 drives the spline shaft 15 to rotate when working. The spline sleeve 19 is fixed to the movable plate bearing 17 through a retaining spring, and is further installed on the A-station movable plate 9 of the A-station. The movable driving wheel 18 is fixed to the spline sleeve 19, so that when the A-station movable plate 9 of the A-station translates, the movable driving wheel 18 is driven to translate through the spline sleeve 19. The combination of the spline shaft 15 and the spline sleeve 19 is a standard part, which is generally used to transfer the power of the spline shaft to the movable part through the spline sleeve. Therefore, the power of the motor 1 can be transmitted to the movable driving wheel 18 through the spline shaft 15 and the spline sleeve 19 combination, and the power transmission is not affected when the movable driving wheel 18 moves. The fixed driving wheel 20 is directly fixed on the spline shaft 15, so that the power of the motor 1 can be transmitted to the fixed driving wheel 20 through the spline shaft 15.

The middle plate 42 of the driving shaft of the B station, the front plate 43 of the driving shaft of the B station, and the rear plate 40 of the driving shaft of the A station and the B station are installed and fixed on the B station bottom plate 44, and are respectively located at the front, middle and rear positions of the power transmission assembly of the B station. The rear plate 40 of the driving shaft of the A station and the front plate 43 of the driving shaft of the B station are used to fix the limit screw 12 and the spline shaft 15. The front plate 43 of the driving shaft of the B station is used to install the fixed side rail 48 of the A station. The middle plate 42 of the driving shaft of the B station is used to install the fixed side rail 46 of the B station.

[0030] Screw support seat No. 1 7 is installed on the rear plate 40 of the driving shaft of station A and station B, and screw support seat 23 is installed on the front plate 43 of the driving shaft of station B. Screw support seat No. 1 7 and screw support seat 23 fix the screw 12 between the front plate 43 of the driving shaft of station B and the rear plate 40 of the driving shaft of station A and station B through the screw front end bearing 8 and bearing 24. The screw locking nut 25 locks the screw 12 to prevent the axial shaking of the screw 12 and ensure that the freedom of rotation of the screw 12 is not restricted. The screw 12 and the two screw nuts 10 form a screw assembly, so that the rotation of the screw 12 can drive the screw nut 10 to move forward and backward in a straight line. The bevel gear 27 is installed on the head of the screw 12 and is locked with a top screw so that the bevel gear 27 drives the screw 12 when it rotates. There are two B-station moving plates 41 for supporting A-station and B-station, which are fixed on the slider 14 through the connecting plate 11. The linear guide composed of the slide rail 13 and the slider 14 is installed on the B-station bottom plate 44, so that the B-station moving plate 41 can be translated along the direction of the slide rail 13.

[0031] The B-station moving plate 41 of the A-station is installed between the middle plate 16 of the A-station driving shaft and the front plate 21 of the A-station driving shaft through the screw nut 10 and the screw 12, so that the screw 12 can rotate and drive the B-station moving plate 41 of the A-station to translate between the middle plate 42 of the B-station driving shaft and the front plate 43 of the B-station driving shaft through the screw nut 10. The B-station moving plate 41 of the B-station is installed between the middle plate 42 of the B-station driving shaft and the rear plate 40 of the A-station B-station driving shaft through the screw nut 10 and the screw 12, so that the screw 12 can rotate and drive the B-station moving plate 41 of the B-station to translate between the middle plate 42 of the B-station driving shaft and the rear plate 40 of the A-station B-station driving shaft through the screw nut 10. The motor 1 is installed on the rear plate 40 of the A-station B-station driving shaft through the motor connecting seat 2.

[0032] The spline shaft 15 is installed between the front plate 43 of the driving shaft of the B station and the rear plate 40 of the driving shaft of the B station of the A station through the power bearing 6 and the driving shaft bearing 23. The spline shaft 15 is connected to the main shaft of the motor 1 through the coupling 3, so that the spline shaft 15 is driven to rotate when the motor 1 is working. The spline sleeve 19 is fixed to the movable plate bearing 17 through a retaining spring, and is further installed on the B station movable plate 41 of the B station. The movable driving wheel 18 is installed and fixed on the spline sleeve 19, so that when the B station movable plate 41 of the B station is translated, the movable driving wheel 18 is driven to translate through the spline sleeve 19. The combination of the spline shaft 15 and the spline sleeve 19 is a standard part, which is generally used to transmit the power of the spline shaft to the movable part through the spline sleeve. Therefore, the power of the motor 1 can be transmitted to the movable driving wheel 18 through the spline shaft 15 and the spline sleeve 19 combination, and the power transmission is not affected when the movable driving wheel 18 moves. The fixed driving wheel 20 is directly fixed on the spline shaft 15 , so that the power of the motor 1 can be transmitted to the fixed driving wheel 20 through the spline shaft 15 .

[0033] like Figure 4As shown, the structure of the movable side track includes: a moving driving wheel 18, a spline sleeve 19, a track profile 35, a track cover plate 36, a belt 37, a belt support plate 38, and a pulley 39. The movable side track 47 of the A station is symmetrical in structure and has the same parts as the movable side track 45 of the B station. The track profile 35 of the movable side track 47 of the A station is installed on the A station moving plate 9 and the B station moving plate 41 of the A station, so that the screw rod 12 can rotate to drive the movable side track 47 of the A station to move forward and backward. The track profile 35 of the movable side track 45 of the B station is installed on the A station moving plate 9 and the B station moving plate 41 of the B station, so that the screw rod 12 can rotate to drive the movable side track 45 of the B station to move forward and backward.

The belt 37 is installed in four pulleys 39 and on the mobile driving wheel 18, so that the power of the motor 1 can be transmitted to the belt 37 through the mobile driving wheel 18. The belt support plate 38 is installed on the side of the track profile 35 and in the middle of the belt 37 to ensure that the belt 37 is supported by the belt support plate 38 and does not fall.

[0034] like Figure 5 As shown, the structure of the fixed side track includes: a fixed driving wheel 20, a track profile 35, a track cover 36, a belt 37, a belt support plate 38, and a pulley 39. The fixed side track 48 of the A station is symmetrical with the fixed side track 46 of the B station in structure and has the same parts. The track profile 35 of the fixed side track 48 of the A station is installed on the front plate 21 of the driving shaft of the A station and the front plate 43 of the driving shaft of the B station. The track profile 35 of the fixed side track 46 of the B station is installed on the middle plate 16 of the driving shaft of the A station and the middle plate 42 of the driving shaft of the B station. The track cover 36 is installed above the track profile 35 for dust prevention and workpiece limiting. Four pulleys 39 are installed on the side of the track profile 35. The belt 37 is installed in the four pulleys 39 and installed on the fixed driving wheel 20, so that the power of the motor 1 can be transmitted to the belt 37 through the fixed driving wheel 20. The belt support plate 38 is installed on the side of the track profile 35 and in the middle of the belt 37, which can ensure that the belt 37 is supported by the belt support plate 38 and does not fall down.

[0035] like Figure 6As shown, the structure of the helical gear linkage width adjustment assembly includes: a helical gear 27, a shaft bearing 28, a No. 1 bearing fixing seat 29, a hexagonal shaft bearing 30, a No. 2 bearing fixing seat 31, a locking nut 32, a hexagonal shaft 33, and a shaft 34. The helical gear linkage width adjustment assembly is installed on the equipment machine through the No. 1 bearing fixing seat 29 and the No. 2 bearing fixing seat 31. The shaft 34 passes through the No. 1 bearing fixing seat 29 through the shaft bearing 28, so that the shaft 34 can rotate around the axis. The hexagonal shaft 33 passes through the No. 2 bearing fixing seat 31 through the hexagonal shaft bearing 30, so that the hexagonal shaft 33 can rotate around the axis. The hexagonal shaft 33 is equipped with a hexagonal gear 27 at one end, and the hexagonal gear 27 is locked by a top screw. The other end of the hexagonal shaft 33 is equipped with a locking nut 32, which can prevent the axial shaking of the hexagonal shaft 33 and ensure that the freedom of rotation of the hexagonal shaft 33 is not restricted. The rotating shaft 34 is equipped with a bevel gear 27, which is locked by a top screw and cooperates with the teeth of the bevel gear 27 on the hexagonal rotating shaft 33, so that when the hexagonal rotating shaft 33 rotates, the bevel gear 27 can simultaneously drive the rotating shaft 34 to rotate. A bevel gear 27 is installed at each end of the rotating shaft 34, and the bevel gears 27 are installed in the same direction. The bevel gears 27 are locked by a top screw and are used to rotate with the rotating shaft 34. Figure 2 , Figure 3 The teeth of the helical gear 27 in the rotating shaft 34 cooperate, so that when the rotating shaft 34 rotates, the helical gear 27 can simultaneously drive the screws on the power transmission assembly of the A station and the power transmission assembly of the B station to rotate, and further drive the translation of the movable side track 47 of the A station and the movable side track 45 of the B station, so as to produce a linkage effect, so that the track width can be synchronously adjusted by rotating the hexagonal rotating shaft 33. At the same time, as long as the top screws of the helical gears 27 at both ends of the rotating shaft 34 are loosened to ensure that the screws on the power transmission assembly of the A station and the power transmission assembly of the B station on the left and right sides do not produce linkage, the track spacing at the left and right ends of the track can be adjusted by manually rotating the two screws.

[0036] like Figure 7As shown, the lead screw nut 10 is provided with three arc-shaped waist holes 10.1. The screws passing through the arc-shaped waist holes 10.1 can lock or loosen the lead screw nut 10 and the A station moving plate 9 or the B station moving plate 41. First loosen the screws, and adjust the track spacing of the two stations by rotating the lead screw nut 10. After locking the screws, it can be ensured that the track widths of the two stations remain consistent. The light source conveying device in this embodiment is provided with two stations, and the two stations are arranged side by side. Each station has two tracks, one of which is installed on the fixed side and the other is installed on the movable side. The fixed side tracks of each station are located on the same side, and the movable side tracks are on the other side. The fixed side tracks are fixed to the base plate, and the movable side tracks are installed on the base plate through a linear guide rail, so that the movable side tracks can be translated along the linear guide rail. Two lead screw nuts are installed on the movable side rails of the two workstations, and the lead screw nuts are provided with trapezoidal threads 10.2. Two trapezoidal lead screws pass through the lead screw nuts respectively. The heads of the trapezoidal lead screws are provided with helical gear-linked width-adjusting components, which can make the two trapezoidal lead screws rotate synchronously. When the helical gear-linked width-adjusting components drive the two trapezoidal lead screws to rotate simultaneously, the movable side rails can be driven to translate along the linear guide rails at the same time, thereby realizing synchronous width adjustment of the double-station rails.

[0037] The power source uses a motor connected to a spline shaft through a coupling, and a spline sleeve is installed on the active pulley of the movable side track, so that the movement of the movable side track does not affect the provision of driving force, and meets the motor power supply in a narrow space. There are two sets of power sources, each of which provides power for a separate station to achieve independent work of the two stations. The helical gear linkage width adjustment component can loosen the fixed top screw on the helical gear, and can freely adjust the angles of the trapezoidal lead screws, which is convenient for adjusting the spacing between the two ends of the track at the same station. After locking the top screw, the spacing within the same track remains consistent. The screw nut installation hole is provided with an arc waist hole 10.1, and the track spacing of the two stations can be adjusted by rotating the screw nut. After locking and fixing, the track width of the two stations can be ensured to be consistent.

[0038] The above design scheme can achieve the following technical effects: 1. The motor is connected to the pulley through the spline shaft and spline sleeve from the outside of the track and is not installed on the track, which is suitable for the transportation of small workpieces such as ceramic light sources; 2. The double-station track can be synchronously adjusted in width through the two screw nuts on the screw, which is convenient for product switching; 3. The double-station has an independent power source to meet the independent operation of the double-station ceramic light source; 4. The track spacing of different stations can be fine-tuned to reduce the requirements for processing and installation accuracy; 5. The track is narrow and long, and the original spacing between the two ends of the track is prone to processing and installation errors. The two ends of the track in this case can be fine-tuned to be consistent, reducing the requirements for processing and installation accuracy; 6. The motor as the power source is located at the rear to facilitate electrical wiring, and the bevel gear linkage width adjustment component is located on the front operating surface to facilitate manual operation.
