Description

Counting Device for Terminal Clamping Machine

The present invention relates to a terminal binder, and more specifically, to a terminal binder for crimping and coupling the wires and terminals supplied to the molding die, the terminal binder for reliably performing the count of the number of operations according to the completion of each working stroke. It relates to the frequency counting mechanism of the machine.

In general, the power line and the signal line constituting a predetermined electric circuit is manufactured in the form of a terminal bite at one end of the wire to facilitate the circuit configuration, such a product is a wire supply, a terminal supply, a terminal binder, a clamping machine It is completed through the device which organically connected the back.

At this time, the terminal binder is composed of a transfer unit for transferring the wires and terminals to the molding die one by one, a punch moving unit for completing the binding by lowering the punch to a predetermined height. Since each part is mechanically connected to the up and down ram of the clamping machine, it is possible to continuously manufacture products having the same specifications.

1 is an exemplary view showing main parts of a conventional terminal binder and a counter mechanism.

In the terminal binder, a molding die 11, a punch die 12, a transfer die 13, and the like are integrally assembled, and a punch holder 14 is mounted on the punch die 12 so as to move up and down, and the transfer die 13 ), The finger holder 17 is pivotably mounted. The shank 15 is fixed to the upper portion of the punch holder 14 and the punch 16 is fixed to the lower portion. A roller 17a is mounted on the upper end of the finger holder 17 and a finger 18 is mounted on the lower end so as to be able to swing. The roller 17a of the finger holder 17 is in contact with the guide 14a fixed to the side of the punch holder 14.

Accordingly, when the ram of the clamping machine is connected to the shank 15 to raise the punch holder 14, the finger holder 17 rotates in conjunction with the finger 18, while the finger 18 bites and advances the terminal, and the punch 16 also increases. do. Then, when the clamping machine ram is lowered, the punch 16 binds the terminals on the forming die 11 and at the same time, the finger 18 moves backwards to prepare for transporting the next terminal.

At this time, a limit switch 19 for detecting the up and down movement of the punch holder 14 is installed to generate one signal every stroke of the punch holder 14, and this signal is counted using the circuit of the controller. The number of operation of the punch holder 14 using the limit switch 19 is used as information for determining the production amount and the defective rate according to the terminal binding operation or determining the repair and replacement cycle of the terminal binder.

However, when the limit switch 19 is used, not only the contactor wears out due to the contact with the punch holder 14, but also the durability decreases, and noise is introduced by the impact force generated during the operation of the punch holder 14, and errors in coefficient It is easy to cause. Even if a non-contact type, such as a proximity switch instead of the limit switch 19, there is a disadvantage that it is not easy to block the electrical noise.

Accordingly, the present invention solves the above-mentioned disadvantages, and in the terminal binder for crimping and combining the wires and terminals supplied to the molding die, the terminal binding is performed so that the count of the number of operations according to the completion of each working stroke is performed reliably. It is an object of the present invention to provide a counting mechanism for the operation of the machine.

In order to achieve this object, the present invention, in the terminal binder for pressing the terminal by the action of the punch 16 by moving the punch holder 14 up and down on the punch die 12: of the punch holder 14 A magnet 20 recessed and mounted in one recess 24; And an insertion hole 22 at a position corresponding to the magnet 20 in a non-contact manner on one side of the punch die 12, and sequentially changing the number from the minimum unit to the maximum unit by the magnetic force of the magnet 20. It is characterized in that it comprises a counter 30 for counting.

As another feature of the present invention, the counter 30 has a number disc 31 having two driving jaws 31a on one side and ten driven jaws 31b on the other side and teeth 31c on one side of the minimum unit. And a swing mechanism 32 that performs a seesaw movement by the magnetic force of the magnet 20, a drive mechanism 33 that converts the seesaw movement of the swing mechanism 32 into a rotational movement of the teeth 31c, The movable plate 34 repeatedly protrudes long and short wing pieces on the shaft 36 so that one digit rotation of an adjacent upper unit is caused by one rotational movement of the lower unit in the number disc 31. .

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

Figure 2 is a perspective view showing a terminal binder with a counter mechanism according to the present invention, Figure 3 is a perspective view showing a partially cut counter applied to the present invention, Figure 4 is a longitudinal cross-sectional view of the counter applied to the present invention, and 5 is a cross-sectional view showing a state of use of the present invention, respectively.

The present invention relates to a terminal binder for compressing a terminal by the action of the punch 16 by moving the punch holder 14 up and down on the punch die 12, the molding die 11, the punch die 12, In the construction and operation of the transfer die 13, punch holder 14, finger holder 17 and the like, the sameity as the conventional terminal binder described above is maintained.

At this time, according to the present invention, the magnet 20 is mounted recessed on one side of the punch holder 14. The magnet 20 uses an anisotropic ferrite magnet that is small in size and has high reliability regardless of the composition. Anisotropic ferrite magnets are widely used as circuit elements of precision control devices such as motors and rotation sensors as well as various electronic products such as televisions, camcorders, and audio devices.

The magnet 20 processes and press-fits the depression 24 on the opposite side from which the punch 16 operates in the punch holder 14. After the press-fit magnet 20 secures the interference exclusion space in the depression 24 so as not to protrude beyond the surface of the punch holder (14). By securing such an interference exclusion space, even if the impact force according to the operation of the punch holder 14 during the operation is prevented from being separated.

In addition, according to the present invention, the counter 30 which sequentially varies the number from the minimum unit to the maximum unit by the magnetic force of the magnet 20 and counts the non-contact with the magnet 20 at one side of the punch die 12. It is installed in the rear insertion space 22 to be processed to a predetermined depth in the corresponding position. Counter 30 is used in a variety of fields, including odometer of the vehicle, in the present invention, in particular, the operation reliability and durability according to the impact should be superior to other applications.

Such a counter 30 is fixed in a state where the separation is prevented by the bracket 35 for closely supporting the rear insertion space 22 of the punch die 12.

In the counter 30 of the present invention, as illustrated in FIGS. 3 and 4, a plurality of number discs 31 are provided on one shaft 36 and interposed between each number disc 31. The chair 34 is freely rotatable along another axis 37 adjacent thereto. The digital number plate 31 is connected to the driving mechanism 33 on one side, and the driving mechanism 33 is connected to the swing mechanism 32 which is operated by the seesaw again by the magnet 20.

The numeric disc 31 has two driving jaws 31a on one side and ten driven jaws 31b on the other side and has teeth 31c on one side of the minimum unit. More specifically, the digit of the smallest unit is a configuration in which the teeth 31c are formed on one side and the driving jaw 31a is formed on the other side, and the digit of the largest unit is a configuration in which only the driven jaw 31b is formed on one side. On the other hand, the one between the minimum digit and the maximum digit is the same configuration, the driving jaw 31a on one side and the driven jaw 31b on the other side are formed.

As shown in FIG. 4, the swinging mechanism 32 oscillates around the fixing pin 38 by the magnetic force of the magnet 20 and moves in a seesaw. A magnet 20a having the same polarity is attached to one side of the bottom of the rocking mechanism 32 facing the magnet 20.

However, the swinging mechanism 32 may be provided with magnets 20a at both ends thereof. However, more preferably, the magnet 20a is installed only at one end and the spring 20b is supported at the other end, which is an accurate swing movement of the upper and lower strokes of the punch holder 14 in which the magnet 20 is inserted. This can be caused.

On the other hand, the drive mechanism 33 converts the rocking motion of the rocking mechanism 32 into the rotational movement of the teeth 31c, it is possible to use a known ratchet mechanism (rachet) that allows only one-way movement.

The mover 34 is formed into a gear shape and repeatedly protrudes long and short blade pieces on the shaft 36 so that one digit of an adjacent upper unit is formed by one rotational movement of the lower unit in the number disc 31. Allow rotation.

In other words, in the configuration of the movable element 34 which repeatedly protrudes the long and short wing pieces on the shaft 36, the position of the short wing pieces is to be caught only by the driven jaw 31b of the upper unit number plate 31. The long wing piece is arranged so as to be simultaneously caught by the driven jaw 31b of the upper unit number plate 31 and the driving jaw 31a of the lower unit number plate 31, and the number disc 31 ), One rotation of the lower unit causes one digit rotation of the adjacent upper unit.

In other words, while the number disc 31 of the lower unit is not rotated by the short wing piece of the mover 34 during one rotation, it reaches the driving jaw 31a of the number disc 31 to be rotated. When the short wing piece and the adjacent long wing piece of the mover 34 are caught by the driving jaw 31a, the driven jaw 31b of the upper unit number plate 31 positioned on the side is simultaneously rotated. .

In the operation according to the present invention, the swing mechanism 32 of the counter 30 is one stroke by the magnetic force of the magnet 20 while the punch holder 14 finishes the one stroke of raising and lowering by the ram of the clamping machine. Complete the rocking motion. As a result, the swinging mechanism 32 rotates the minimum unit digit of the numeric disc 31 by one scale, and when the digit of the minimum unit rotates one revolution, the adjacent digit is rotated by one scale at the same time.

In the present invention, since the swing mechanism 32 is configured to operate in a mechanical connection from the number disc 31 to the counting operation even when the impact force is transmitted by the ram of the clamping machine.

According to the above configuration and operation, the present invention has the effect of reliably performing the coefficient of the number of operation according to the completion of each working stroke in the terminal binder for crimping and coupling the wires and terminals supplied to the molding die.

It is apparent to those skilled in the art that the present invention is not limited to the embodiments described, and that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or modifications will have to belong to the utility model registration claims of the present invention.
