Description

Technical Field

[0001] The invention relates to the field of watch production equipment, in particular to a watch production line tray positioning device. Background Art

[0002] The production of watches is an extremely precise process. The interior of a watch is mainly composed of gear transmission, winding and loosening of the mainspring, and the escapement speed regulator. In the past, the user had to tighten the mainspring at fixed intervals. Now the mainspring can collect and use the displacement caused by the user's daily life to tighten the mainspring, which can reduce the inaccurate time caused by the loosening of the mainspring. At the same time, the gears inside the watch can achieve regular changes between different time units through different transmission ratios. The escapement speed regulator can make the pointer located in the visible area of ​​the dial rotate regularly at fixed intervals to avoid the influence of external forces that cause the pointer's speed to be unstable.

[0003] During the production process of watches, watchmakers are required to assemble the various parts of the watches with delicate operations to avoid waste of high-value-added watch products. Therefore, in watch production lines with multiple disc-like parts of different specifications, the use of pallets can effectively avoid the loss of parts. Therefore, there is a need for equipment that can help watchmakers clearly identify the positions of various parts to help them improve the manufacturing efficiency and yield rate of watches.

DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2 As shown, a positioning device for a watch production line tray 2 includes a connecting transmission rod 1, and a plurality of trays 2 are hinged on the side of the connecting transmission rod 1 through a connecting rod 15. The tray 2 includes a spring plate 21, a gear plate 22 and at least a plurality of annular plates 23. The bottom of each tray 2 is connected to an arc frame 24 and a motor 25, and displacement support blocks 3 are arranged at both ends of the arc frame 24.

[0030] The outer side of the connecting transmission rod 1 is provided with a first cross-arranged slide rail 11, and a plurality of movable blocks 12 are arranged along the axis of the connecting transmission rod 1 at the intersection of the first slide rail 11. The movable block 12 is movably connected to the connecting transmission rod 1, and the movable block 12 is hinged with a swing rod 13 on the side facing the intersection of the first slide rail 11. The intersection of the first slide rail 11 is provided with an anti-slipping strip 14 matching the track of the intersection. The connecting rod 15 slides along the first slide rail 11 into the anti-slipping strip 14 area, and then moves to the intersection of the first slide rail 11 and connects with the two swing rods 13 at the intersection. The swing rod 13 is touched, and then the position of the swing rod 13 is changed according to the running direction of the connecting rod 15. When the connecting rod 15 passes through the intersection of the first slide rail 11 from above to below the intersection, the swing rod 13 above the intersection of the first slide rail 11 will swing, and at the same time, one end of the swing rod 13 below the intersection of the first slide rail 11 will be subjected to pressure, and then the pressure on one end of the swing rod 13 will be transmitted to the movable block 12 connected to the other end of the swing rod 13, thereby controlling the movable rod to slide downward, and at this time the connecting rod 15 can enter below the intersection in the first slide rail 11.

[0031] like Figure 4 and Figure 5 As shown, the displacement support block 3 includes a ratchet 31, a displacement frame 32 and an adsorption block 33. The ratchet 31 is hinged on both end surfaces of the arc frame 24. The displacement frame 32 is sleeved on the outer side surface of the ratchet 31. The inner side surface of the displacement frame 32 is provided with a one-way tooth 34 matching the ratchet 31 and meshing with the ratchet 31. The outer side surface of the displacement frame 32 is provided with a symmetrical second slide rail 35. The adsorption block 33 is slidably connected in the second slide rail 35. The displacement frame 32 is provided with a third slide rail 36 on the side facing the arc frame 24. One end of a stabilizing block 37 is slidably connected in the third slide rail 36. The other end of the stabilizing block 37 is connected to the arc frame 24.

[0032] Under the meshing of the ratchet wheel 31 and the one-way teeth 34 in the displacement frame 32, the rotation direction of the ratchet wheel 31 can be controlled by the motor 25 at the bottom of the tray 2 to control the transmission of force between the ratchet wheel 31 and the one-way teeth 34, thereby controlling the displacement frame 32 to move upward or downward, thereby controlling the relative position of the displacement frame 32 and the arc frame 24;

[0033] After the trays 2 connected by the connecting rod 15 change their positions along the first slide rail 11, when two arbitrary trays 2 present a vertically symmetrical positional relationship, the displacement racks 32 connected thereto also immediately present an upward and downward position change. According to the rotation of the ratchet wheel 31 and the connection of the adsorption block 33, the upper and lower displacement racks 32 can be controlled to be movably connected, thereby providing support for the trays 2, thereby preventing the watch parts from being damaged due to the loss of control of the trays 2.

[0034] At the same time, a stabilizing block 37 is provided between the displacement frame 32 and the arc frame 24 and is slidably connected to the second slide rail 35, which can effectively prevent the displacement frame 32 from being displaced in the left and right directions when the ratchet 31 drives the displacement frame 32 to move, so that the adsorption blocks 33 on the side of the displacement frame 32 after the position change can be normally connected after adjusting their positions along the third slide rail 36. At the same time, when there is no corresponding displacement frame 32 between the upper and lower parts, when the tray 2 is still below the intersection of the first slide rail 11, the displacement frame 32 can still be controlled by the ratchet 31 to make the bottom of the displacement frame 32 normally contact with the employee's operating table surface, thereby continuing to provide support.

[0035] like Figure 2 and Figure 3 As shown, a spring groove 211 is provided inside the spring disc 21, a spring shaft groove 212 is provided at the center of the spring groove 211, one end of a movable button 213 is provided inside the spring groove 211, a plurality of rubber protrusions 215 are provided on one end surface of the movable button 213 facing the inside of the spring disc 21, the other end of the movable button 213 passes through the spring disc 21 and is led to the outer side surface of the spring disc 21, the movable button 213 passes through the side surface of the spring disc 21 and is connected with the spring groove 211, a telescopic structure is provided inside the movable button 213, a force unloading spring 214 is sleeved on the outer side of the movable button 213, and the force unloading spring 214 weakens the force of the movable button 213 guided from the outer end of the spring disc 21 to the inner end of the spring disc 21 through its own telescopic movement;

[0036] After the mainspring is tightened in the mainspring groove 211, the mainspring begins to gradually gather in the direction of the mainspring shaft groove 212. During the tightening process of the mainspring, continuous compression of external force is required. At this time, one end of the movable button 213 provided with a rubber protrusion 215 can contact the mainspring. At the same time, the unloading spring 214 inside the movable button 213 can reduce the damage to the surface of the mainspring by the force applied by the movable button 213 after the mainspring is tightened to the limit position. At the same time, the rubber protrusion 215 on the end face of the movable button 213 can also reduce the damage to the surface of the mainspring, which can better enhance the auxiliary effect of the movable button 213 on tightening the mainspring.

[0037] like Figure 6 and Figure 7 As shown, a plurality of internal gears 221 with the same module are arranged in the gear plate 22, and the plurality of internal gears 221 are coaxially arranged, and the plurality of internal gears 221 are arranged in a linear array along the coincident axis. The internal gears 221 are arranged in sequence according to the number of teeth. The closer to the top of the gear plate 22, the fewer the number of teeth of the internal gear 221, and the closer to the bottom of the gear plate 22, the more the number of teeth of the internal gear 221;

[0038] A gear shaft groove 225 is provided at the bottom of the gear plate 22, and a top rod 222 is sleeved on the outer side of the gear shaft groove 225. One end of the top rod 222 is connected to the bottom of the gear shaft groove 225, and the other end of the top rod 222 passes through the bottom of the gear plate 22 and is connected to a handle 223. The handle 223 controls the top rod 222 to move toward the top of the gear plate 22 by telescoping, thereby controlling the gear in the inner gear 221 to separate from the gear plate 22.

[0039] Gears with different numbers of teeth can be stored in the gear plate 22. When the tray 2 rotates, the meshing of the internal gear 221 and the gear can help the gear plate 22 to fix the gear, while preventing the tooth surface of the gear from being damaged due to rotation during movement. By controlling the handle 223 to move upward, the push rod can be controlled to push upward, thereby driving the gear in the gear groove 224 to move upward, and then the gear plate 22 can be removed and assembled into the watch.

[0040] like Figure 7 and Figure 8 As shown, the spring disk 21 and the gear disk 22 are both symmetrically provided with an annular disk 23 with the connecting transmission rod 1 as the center, and a plurality of annular grooves 231 are provided on the surface of the annular disk 23, and an annular top block 232 is embedded in the annular groove 231. The annular top block 232 controls itself to move toward the top surface of the annular disk 23 by the force on the bottom, thereby controlling the top of the annular top block 232 to move out of the annular groove 231;

[0041] In addition to the mainspring and gears, other parts in the clock can be placed on the circular disk 23. The top surface of the circular disk 23 is a flat and smooth surface. A circular top block 232 is provided in the circular groove 231 and is engaged with it. The bottom of the circular top block 232 is partially located outside the circular groove 231. By pushing, the top of the circular top block 232 can exceed the range of the circular groove 231, and then the parts on the top surface of the circular disk 23 can be pushed to separate the parts from the top surface of the circular disk 23, making it easier for employees to take the parts.

[0042] First, the parts required for making the clock are placed on the clockwork disc 21, the gear disc 22 and the ring disc 23 according to the function of the tray 2, and the specific position of the connecting rod 15 on the first slide rail 11 is controlled according to the demand. The rotation of the ratchet wheel 31 is controlled according to the stop position of the tray 2, and then the state of the displacement frame 32 is adjusted. According to whether the displacement frame 32 is docked with another displacement frame 32, it is selected whether to use and adjust the adsorption block 33. After that, the employee can tighten the clockwork in the clockwork disc 21 and use the movable button 213 for assistance. After tightening the clockwork in the clockwork disc 21, the clockwork box in the clockwork can cooperate with the clockwork disc 21, so as to tighten the clockwork. The gear is taken out and installed into the gear plate 22 of the gear plate 22. The gear can be moved while limiting its movement, avoiding the situation in which the gear falls and is damaged when it is moved in the past. When the gears need to be meshed and assembled, the handle 223 can be pushed to push all the gears out of the gear groove 224, so that the gears can be meshed with each other according to the number of teeth. For the parts placed on the circular ring plate 23, most of them are selected as some auxiliary parts. When the parts need to be taken, force can be applied to the bottom of the circular ring top block 232, so that the parts on the top of the circular ring plate 23 can be easily taken out for the matching of the parts in the watch.
