Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a circuit board carrier device for carrying a plate-shaped circuit board mounted thereon, and more particularly to an improved structure of a vertical carrier path in a carrier path having different heights of pass lines.

[0002]

[Prior art]

 In the circuit board manufacturing apparatus, generally, a circuit board transfer device for transferring the manufactured circuit board a is used. When connecting units having different heights of the pass lines to produce a line, For example, the inclined conveyor 1 shown in FIG. 3 or the vertical conveying path 2 by the vertical reciprocating operation shown in FIG. 4 is often used as the conveying path between the units having different heights.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional circuit board transporting path, for example, when the inclined conveyor 1 shown in FIG. 3 is used, if the height difference d between the path lines is large, the entire length of the conveyor becomes long. In that case, a large floor area for arranging the transfer device is required, and at the same time, the total line length is increased. Further, for example, when the conveyance path 2 for vertically conveying by the vertical reciprocating motion of FIG. 4 described above is used, it is possible to reduce the area occupied by the device, however, the movement time at the time of ascending and descending is reduced. It's dead time. Therefore, when the cycle time for transporting the work, which is the circuit board a, is short, it is necessary to move the vertical transport path up and down at high speed, which limits the mechanical limit of the vertical drive device such as the hydraulic cylinder 3. There was a problem that it became faster and the lifetime of the device was shortened.

Therefore, in the present invention, the problems in the above-described conventional circuit board transfer path are examined, that is, in the circuit board transfer device having the transfer paths with different heights of the pass lines, these are different. A circuit board can be transported between high-pass lines, its floor space is small, and it can handle high-speed work transport cycle time without dead time, and has a long life. It is an object of the present invention to provide a carrier device.

[0005]

[Means for Solving the Problems]

 That is, in order to achieve the above-mentioned object of the present invention, it is proposed that at least two conveying paths having different heights of the pass lines are provided, and between these conveying paths, a circuit from one conveying path is provided. A circuit board transfer device that transfers a board in the vertical direction and transfers it to the other transfer path, and the length of the circuit board to be transferred is between two transfer paths with different heights of the path line. A gap with a width approximately equal to the length is provided, a chain that moves in the vertical direction is arranged in this gap, and a receiving plate that is approximately equal to the length of the circuit board is attached to the chain to reduce the height difference of the pass line. A plurality of circuit board transfer devices are mounted at a pitch on the vertical conveyors.

[0006]

[Action]

 According to the circuit board carrier proposed by the present invention, a vertically moving chain is used to carry the carrier vertically, so that a floor area for installing the machine is not required so much. Even if there is a large difference in height, it can be installed if there is a gap with a width almost equal to the length of the circuit board. Also, by making the spacing of the receiving plates, which are attached to the above chains and on which the circuit boards are placed and conveyed, the same as the pitch of the difference in the height of the path lines, the push-out operation and push-in of the circuit components can be performed. Since the operations can be performed at the same time, the dead time when moving the workpiece in the vertical direction can be eliminated, and it is possible to sufficiently cope with a short workpiece transfer cycle, and the mechanism does not require high-speed and abrupt movement. Therefore, it is possible to extend the lifetime of the device.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a circuit board transfer apparatus according to an embodiment of the present invention. In the figure, reference numerals 10 and 10 denote a first conveyor forming a transfer path having a first height. The belt is a belt on which a circuit board a to be transported, which is manufactured by a manufacturing apparatus (not shown) or the like, is transferred at a predetermined interval in the direction of the arrow. Further, a push-pusher 20 for pushing in the circuit board a conveyed on the first conveyor belts 10 and 10 is provided between the two conveyor belts 10 and 10. ing.

Following the first conveyor belts 10 and 10, a second substrate different in height from the first conveyor path is provided with a width slightly longer than the length L of the circuit board a to be conveyed. The transport path of the second conveyor belt is formed by the second conveyor belts 30, 30. In this embodiment, the second transport path is located higher than the first transport path. Further, reference numerals 11 and 11 in the drawing are pulleys of the first conveyor belt, and reference numerals 31 and 31 are pulleys of the second conveyor belt.

A vertical transport path is formed between the first and second transport paths. That is, this vertical transport path is configured by arranging four vertical transport loop chains 50, 50 ... Which are arranged side by side in the vertical direction. As is clear from the figure, these vertical transport chains are arranged in two sets of two, each corresponding to the left and right belts of the horizontal transport conveyor.

Further, receiving plates 55, 55 extending in the horizontal direction are attached on the loop-shaped chains 50, 50 for vertical conveyance of each set. That is, a plurality of these receiving plates 55 1, 55 ... Are provided on the outer peripheral side of the loop-shaped chain at a pitch corresponding to the height difference d between the first transport path and the second transport path (this embodiment). 4 pieces) are mounted side by side in the horizontal direction. Further, reference numerals 51 to 54, 51 'to 54' in the figure are pulleys for rotationally driving the above-described vertical transport loop chains 50, 50, ..., and "" is a lower side in the figure. Shows the pulley. Further, in FIG. 1, on the side surface of the loop-shaped chain 50, 50 for vertical conveyance, which is opposite to the surface facing the second conveyor belt (on the left side in the drawing), the above receiving member is provided. A push-out pusher 60 is provided for pushing out the circuit board a placed on the plates 55, 55 toward the second transport path.

Next, FIG. 2 shows a drive mechanism for driving the above-mentioned loop chains 50, 50 for vertical conveyance. For example, the two pulleys 51, 52 shown in the figure are for driving the two front loop-shaped chains 50, 50 of the four loop-shaped chains in FIG. These are fixed to the respective rotary shafts 511 and 521. Further, it is connected to the drive shaft 56 via miter gears 512 and 522, which are a combination of two bevel gears having the same number of teeth for changing the direction to a right angle. A spur gear 61 is attached to the drive shaft 56 at a substantially central portion thereof, and a rotary drive torque is transmitted by a drive gear 64 fixed to an output shaft 63 of an electric motor 62, for example. That is, according to this drive mechanism, it becomes possible to move the pair of left and right loop chains 50, 50 for vertical conveyance at the same speed. The same drive mechanism as described above is also used for the pulleys 53 and 54 for driving the other pair of loop-shaped chains.

The operation of the circuit board carrier according to the present invention described in detail above will be described below with reference to FIG. First, the circuit board a is conveyed onto the first conveyor belts 10 and 10 forming the first conveying path having a low height, and when the circuit board a approaches the end thereof, the pusher 20 operates to move the circuit board a in the arrow direction. , Is attached to the outer circumference of the above-described vertical transport loop chains 50, 50, and protrudes inward to move onto the two receiving plates 55, 55 facing each other. In this state, the vertical transport loop-shaped chains 50, 50 ... Move upward. Then, when the two receiving plates 55, 55 reach the position of the second transport path located above, the push-out pusher 60 operates, that is, the circuit board a is pushed out to push the second conveyor belts 30, 30. Move it up.

At this time, the receiving plates 55, 55 ... Attached on the outer periphery of the vertical conveying loop-shaped chains 50, 50. Since they are arranged at the same pitch as d, the pair of receiving plates 55, 55 coming next to the lower side are at the height of the lower first conveying path. Therefore, simultaneously with the operation of pushing out the circuit board above, the circuit board a to be conveyed next can be pushed onto the next receiving plate 55, 55 by the operation of the pusher similar to the above. By repeating this operation, the circuit board a, which is sequentially conveyed and supplied on the conveyor, is moved without delay in the movement time from the lower conveyance path to the upper conveyance path (that is, the time during which the work is rising is the dead time). However, it is possible to eliminate this dead time).

Further, according to the above-mentioned mechanism, by setting the pitch between the receiving plates 55, 55 to the above-mentioned interval, the dead time during rising of the work is eliminated, so that the driving device itself can operate at high speed and rapidly. No extra exercise is required, which makes it possible to maintain a long life time of the device.

[0015]

[Effect of device]

 As described above, according to the circuit board transfer device of the present invention, since the occupied floor area is small and there is no dead time, it is possible to sufficiently cope with a high-speed work transfer cycle time. It is possible to provide a device with a long lifetime.
