組立方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for assembling a timepiece wheel train, and more particularly to a method for assembling a timepiece wheel train in which a wheel is positioned and regulated in handle holes in two upper and lower substrates.

正する方法がとられていた。Conventionally, when assembling a clock train in which a car is placed between two boards, the lower handle of the car is temporarily placed in the handle hole of the lower board, and then the upper board is placed on top of the upper board, and the positioning of the upper board is done. Therefore, the work of correcting the fallen car, bringing it to the correct position, and positioning and inserting it into the handle hole of the upper board is a method in which a person corrects the fallen car by sagging the car with tweezers etc. was taken.

にこのことはコストアップの要因ともなる。However, in recent years, automatic assembly of watches has been promoted, and efforts have been made to automate the wheel train assembly process as well. However, when assembling the upper board on an automated line, manual work using tweezers or the like to correct the tilting of the car becomes a major obstacle to full automation. Various automatic assembly methods have been proposed as solutions to this problem. These methods include the so-called standing position regulation, which corrects the tilt of the car temporarily mounted on the lower board and positions the upper part in the handle hole of the upper board; There is a method of regulating the standing position by inserting the control jig between two boards placed on the board, but with this method, as watches become smaller and thinner, it is necessary to secure a space for inserting the regulation jig. is becoming increasingly difficult to design. Another method is to restrict the standing position of the car by sticking out a part of the watch components placed near the car, but in this case as well, as watches become smaller and thinner, some of the parts are removed due to the design. It becomes difficult to control the car's standing position because it is difficult to control the car's position in the overhanging space, and this also causes an increase in costs.

る。In the figure, the lower handle 6a of the car 6 is inserted into the lower handle hole 1a of the lower board 1, and the car 6 is temporarily assembled. Around this time, on top of car 6,
Even if the upper board 2 is placed in the correct position on 163b, the upper g3b
and the upper hole 2a of the upper board 2 do not match. Conventionally, in this state, the wheels 6 were manually cut out one by one using tweezers or the like at ℃ temperature, the upper loading slot b was adjusted to the upright position, and then inserted into the upper loading hole 2a of the upper board 2 to assemble the wheel train. was. For this reason, it takes a lot of time and energy to assemble one solid model.
Even if a power-reinforcement mechanical line was set up, this wheel train assembly process was always a bottleneck in the line. 2 is a cross-sectional view of a gear train section showing an embodiment of the present invention for performing position control 11, and the same members as in FIG. 1 are given the same numbers and explanations are omitted. The suction device 7 includes an upper magnetic attraction member 8 made of a magnetic material, a plurality of suction heads composed of an upper coil 9 wound around the upper magnetic suction bow 1 member 8, and current is applied to each upper coil 9. It consists of a mlJ control device 14 for flowing mlJ to the plurality of suction bows 1, and is held in one holder, and the magnetic suction device 7 is positioned above the upper substrate 2. At this time, each upper magnetic attraction member 8 is arranged at a position corresponding to each upper part 2a of the upper substrate 2.Then, this magnetic attraction device 7 is placed in a position corresponding to each upper part 2a of the upper substrate 2. The pull-out prevention device 4 is provided at the assembly station.The pull-out prevention device 4 has a plurality of suction devices including a lower magnetic attraction member 5 made of a magnetic material and a lower coil 6 wound around the lower magnetic attraction member 5. The plurality of suction heads are held in one holder.The removal prevention device 4 is located below the lower substrate 1, and each lower magnetic attraction member 5 is attached to the lower substrate. 1.This pull-out prevention device 4 is also provided at the train train assembly station of the automatic watch assembly machine and is heated to

次に本発明の磁気吸引装置7及び抜防止装置4を使用し
た輪列の組立て方法について説明する。Next, a method of assembling a wheel train using the magnetic attraction device 7 and pull-out prevention device 4 of the present invention will be explained.

車6を仮立てする。下基板1の下柄穴1aに車3の下柄
6aを仮立てした状態は下柄穴1aと下柄6aとが遊嵌
状態にあるため、第1図に示す如く倒れた状態にある。First, the lower board 1 is placed on the removal prevention device 4 so that its lower handle hole 1a is located at the position of the lower magnetic attraction member 5, and the wheel 6 is temporarily mounted on the lower board 1. When the lower handle 6a of the car 3 is temporarily placed in the lower handle hole 1a of the lower substrate 1, the lower handle hole 1a and the lower handle 6a are loosely fitted, so that the lower handle 6a is in a fallen state as shown in FIG.
尚、第2図には一部点線で倒れた状態の車6の例を図示

基板2のネジ締め等を経て輪列の組立てが完了する。Next, the upper substrate 2 made of a non-magnetic material is placed in the proper position on the upper ff 13b, and the magnetic attraction device 7 is placed from above the upper substrate 2.
The upper magnetic attraction member 8 is set in the position where it matches the upper hole 2a of the upper substrate 2. In this state, when current is applied to the lower coil 6 and upper coil 9, the lower magnetic attraction member 5
Since a magnetic field is generated in the magnetic attraction member 8 and the upper magnetic attraction member 8, the arrow (
As shown in A), the vehicle 6 is corrected from falling and is in a standing position. At this time, the current flowing through the lower coil 6 is thicker than the current flowing through the upper coil 9 (if this is done, the lower magnetic attraction member 5 will generate a larger magnetic field than the upper magnetic attraction member 8, so
Even if the wheel 3 is pulled upward by the magnetic force of the upper magnetic attraction member 8, the lower handle 6a does not protrude from the lower handle hole 1a. As mentioned above, when the lower board 2 is lowered in the upright position, the upper case 3b is inserted into the upper handle hole 2a of the upper board 2, and the gear train is assembled by tightening the screws on the upper board 2.

規制効果をより一層高めることができる。It should be noted that the pull-out prevention device does not necessarily need to use magnetic action; for example, it is possible to prevent the lower handle 3a from protruding from the lower handle hole 1a by applying vacuum suction from below the lower handle hole 1a, or to control the dimensions of the upper and lower frames. Depending on the situation, it is also possible to eliminate the suction device from below altogether. Furthermore, if a method such as applying vibration to the lower substrate 1 is added, the rocking motion of the wheel 6 will bring the upper rack 6b and the upper magnetic attraction member 8 closer together, making it possible to effectively utilize the magnetic attraction force. The effect of B's sentence position regulation can be further enhanced.

ない。Figure 3 is a sectional view showing the specific structure of a magnetic attraction device different from that used in Figure 2. In Figure 2, the magnetic attraction device is attached to the upper board after the upper board is placed on top of the vehicle. However, when using the magnetic attraction device shown in Figure 3,
After the upper substrate is vacuum-adsorbed to the substrate adsorption member of the magnetic attraction device, the second step is to position the upper substrate on top of the vehicle.
This is a difference between the embodiment shown in the figure and the embodiment using the magnetic attraction device shown in FIG. The magnetic attraction device shown in FIG. 3 is a device that integrates a device for magnetically attracting a car and a device for vacuum suctioning the upper substrate. In the figure, the magnetic attraction device 17 is connected to the upper substrate 2.
The upper coil 9a is wound around a core 11 of approximately the same size as the upper substrate 2 that is attracted to the substrate attraction member 10.
The upper magnetic attraction member 8 disposed on the center axis of the upper hole 2 a is press-fitted into the core 11 and its tip passes through the substrate attraction member 10 . A substrate suction member 1o for positioning the upper substrate 2 is attached to the lower surface of the core 11. At the center of the magnetic attraction device 17 are the base 12 and the core 11.
A vacuum suction hole 16 is opened which penetrates through to the substrate suction member 10 through the vacuum suction hole 16, and when the upper substrate 2 is vacuum suctioned by the vacuum suction hole 16 and positioned and fixed to the substrate suction member 10, a regular portion on the upper handle 6b is opened. By moving the magnetic attraction device 17 to the position shown in FIG. At this time, a current is applied to the upper coil 9a to generate a magnetic field in the upper magnetic attraction member 8 through the core 11 (as the magnetic attraction device 17 is lowered, the magnetic attraction force is applied to the magnetic material at a certain position). The upper handle 6b is sucked to regulate the standing position of the wheel 6. Furthermore, by lowering the upper substrate 2 vacuum-adsorbed by the magnetic attraction device 17, the upper handle 6b is inserted into the upper handle hole 2a, and the upper handle 6b is inserted into the upper handle hole 2a. The board 2 is assembled. In this state, the upper board can be easily assembled by stopping the vacuum suction and raising the magnetic suction device. Note that when using the magnetic suction device shown in Fig. 3, the upper board can be easily assembled. Similarly, it goes without saying that the magnetic field of the lower magnetically attractive member is made thicker than that of the upper magnetically attractive member.

できた。As shown in each embodiment, the magnetic attraction device of the present invention can generate magnetomotive force in the magnetic attraction member using a coil and excite it to regulate the standing position, or can use a permanent magnet for the magnetic attraction member. Various possibilities are possible, such as raising and lowering the magnetic attraction member to apply a magnetic field to the upper wheel to regulate the standing position of the upper wheel. Since the standing position can be regulated, it is possible to easily incorporate the wheel train into the upper board without inserting a jig near the wheel train or installing a design-wise prevention member to prevent it from collapsing, making it possible to completely mechanize the line. Furthermore, since positioning can be controlled almost instantaneously, assembly work can be completed in a short time, making it possible to fully complete the process within the cycle time of the automated line, making unmanned automatic assembly possible. This made it possible to significantly reduce the cost of watches.
