Description

[0001]
[Industrial application fields]
The present invention relates to a receiver that is arranged in a processing line of a printed wiring board, receives a raw workpiece, inserts it into a vertical rack, and sends it to the next process together with the vertical rack. It relates to a receiver that can be performed at high speed.
[0002]
[Prior art]
In order to complete one printed wiring board, the copper-clad laminate, which is the material, and the half-processed substrate formed from now, drilling and etching, as well as the cleaning and various processes associated with them are performed. Must be given. The processing or processing is performed individually by changing the line or by providing a partition portion in one line. Finally, by applying various processing / processing to the substrate or the like in the line or the partition portion, 1 Two printed wiring boards are completed.
[0003]
Also, looking at the recent situation of copper-clad laminates, which are printed wiring board materials, that is, substrates, for example, printed wiring boards for mobile phones, those with a thickness of 0.05 mm or less will be adopted. In order to handle this in each processing line or process described above, it is necessary to take care. In particular, taking this type of mobile phone substrate as an example, in order to reduce the manufacturing cost, the overall size is usually set to about 500 mm × 600 mm, and this is separated in the final process. A so-called multiple printed wiring boards for a mobile phone can be obtained.
[0004]
In other words, recent printed wiring boards and their material substrates are of a large area and thin, so they are not only very soft and easy to bend, but also subject to air resistance. It is becoming. For this reason, if care is not taken when handling the wiring circuit, it is easily bent and the bent wiring circuit is damaged or a mechanical trouble occurs.
[0005]
Furthermore, when one printed wiring board is taken, the number of wiring circuits formed therein has become very fine, and especially when it is in the middle of manufacture, there is a wiring circuit that has just been etched or plated. It is something that is exposed. For this reason, each wiring circuit is very unstable and easily damaged, and some protection must be taken while the processing is required. This is a more important consideration in the case where the copper-clad laminate, which is the material of the printed wiring board, has become very thin as described above, and when this is to be handled mechanically. It is coming.
[0006]
This type of printed wiring board must be manufactured and processed as much as possible to improve quality and reduce costs. Various processing lines and various devices associated with this type of printed wiring board are required. It has been developed and proposed. For example, Patent Document 1 proposes “a printed wiring board receiving device and a loading device for a rack”, and its basic idea is to perform one processing / processing line and the next processing / processing. This means that a rack for loading a large number of printed wiring boards in the middle of processing is moved between the lines.
[0007]
This rack is for storing a large number of printed wiring boards in an upright or inclined state, so that the printed wiring boards do not come into contact with each other, or the weight of each other does not increase, In addition, since it can be easily transferred to the next line, it is very useful in automating the processing and processing of a large number of printed wiring boards.

[0009]
[Problems to be solved by the invention]
However, in order to receive a printed wiring board or a workpiece that is a semi-finished product and insert it into the rack in an inclined state, not only the number of processes and parts are increased, but the overall apparatus becomes complicated. It is considered that it is necessary to interpose a slip sheet between each work, and it takes a considerable time to insert the work into the rack after receiving the work.
[0010]
Therefore, as a result of various studies by the present inventor, since the workpiece is inserted into the rack and received in an inclined state, the apparatus becomes complicated, and in some cases, it is necessary to use a slip sheet. The idea was to go back to the starting point where it would be better to arrange them vertically apart from each other. First, we developed a vertical rack for placing workpieces vertically.
[0011]
Now, the development of a device that can be inserted into the rack without damaging the received workpiece has been planned. This time, the workpiece that has been sent in a horizontal state is set up and inserted into the vertical rack. As a result, it has been found that the work time is unexpected and the receiving work is inefficient.
[0012]
Therefore, the present inventor has made various studies on how to shorten the work time when standing and inserting the work, which has been sent in a horizontal state after being received, into the vertical rack. As a result, the present invention has been completed.
[0013]
The present invention has been made based on the above circumstances, and the problem to be solved is that the received work can be inserted into the vertical rack in a standing state, and the work can be performed in a short time. That is.
[0014]
That is, first of all, the object of the invention according to claim 1 is that the workpiece received by the machine and sent in a horizontal state can be surely inserted into the vertical rack in a standing state. An object of the present invention is to provide a receiver capable of shortening the working time.
[0015]
Further, the object of the invention according to claim 2 is to achieve the same object as that of the invention of claim 1 above, and to receive the upright workpiece W in a state where there is little impact, and the size. It is an object of the present invention to provide a receiver that can be surely inserted into a vertical rack without damaging the workpieces.
[0016]
[Means for Solving the Problems]
In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“A receiving device 100 that receives a work W such as a printed wiring board or its material substrate sent from a previous process and inserts it into a vertical groove 61 of a vertical rack 60,
A main carry-in path 10 that receives the workpiece W and conveys it into the machine, a first undulating conveyance path 21 that is formed at the front end of the main carry-in path 10 so as to be able to stand up and can stand upright, and this first undulation conveyance At least a second undulating conveyance path 22 disposed at the next stage of the path 21 and laid down after the fall, and a rack conveyance for sending a vertical rack 60 to the outside of the next lower stage of the second undulating conveyance path 22 A path 30 is provided,
When the workpiece W is completely fed onto the second undulation conveyance path 22 in a horizontal state, the first and second undulation conveyance paths 21 and 22 stand up at the same time and begin to feed the workpiece W into the vertical rack 60. When the first undulating and conveying path 21 that has stood up completely sends the workpiece W into the second undulating and conveying path 22, the first undulating and conveying path 21 falls to the horizontal position and is sent next. In addition, the second undulation transport path 22 receives the next workpiece W after the workpiece W is completely fed into the vertical rack 60 and then falls to the horizontal state. Machine 100 "
It is.
[0017]
That is, the receiver 100 according to the first aspect of the present invention has a large number of works W such as a printed wiring board or a material substrate to be completed, which have been sent from the outside to the main carry-in path 10 in a substantially horizontal state. Is received and inserted into the vertical rack 60 in a standing state, and for this purpose, the receiver 100 is provided with an undulating conveyance path 20 for raising each workpiece W in the machine. It is what.
[0018]
In order to achieve the purpose of the receiver 100, it is sufficient that the undulating transport path 20 has at least two of the first undulating transport path 21 and the second undulating transport path 22, In the embodiment shown, the third undulating conveyance path 23 is provided in the next stage of the second undulating conveyance path 22. Here, in order to explain the invention of claim 1, the explanation will be made on the assumption that the undulation conveyance path 20 including only the first undulation conveyance path 21 and the second undulation conveyance path 22 is assumed.
[0019]
First, when the workpiece W is transported on the main carry-in path 10, the first undulation transport path 21 and the second undulation transport path 22 are completely overlaid as shown in FIG. 2 and FIG. 6 (d). When the workpiece W is completely loaded on the second undulation conveyance path 22 (which becomes the third undulation conveyance path 23 in the embodiment) in the final stage, as shown in FIG. The first undulating and conveying path 21 and the undulating and conveying path 20 stand up at the same time while holding the workpiece W therebetween.
[0020]
At this time, as shown in FIG. 1 and the like, an empty vertical rack 60 is carried from the rack carry-in path 50 onto the rack transport path 30 below the undulating transport path 20. Is waiting for the workpiece W to be inserted into each of the longitudinal grooves 61. In addition, as the first undulating and conveying path 21 and the second undulating and conveying path 22 stand up, the inner end side of the main carry-in path 10 is in a state where there is no conveying path as shown in FIG. Further, at this time, the next workpiece W is carried into the entrance side of the main carry-in path 10 and is proceeding on the main carry-in path 10 toward the inner end side.
[0021]
The workpiece W standing up by the undulating conveyance path 20 starts to descend toward the vertical rack 60 by the feed rotation of the roller shaft 21b constituting the first undulating conveyance path 21 and the conveyance roller 21d thereon. When the workpiece W is first removed from the first undulating and conveying path 21 due to this descent, the drive cylinder 21c of the first undulating and conveying path 21 is driven by a signal that detects this, and the swing that supported the entire first undulating and conveying path 21 is driven. The moving arm 21a rotates from the state shown in FIG. 6A to the state shown in FIG. Thereby, while the workpiece | work W is still descend | falling by the other 2nd undulation conveyance path 22, the partial conveyance path by the 1st undulation conveyance path 21 is additionally formed in the inner end side of the main carry-in path 10. become.
[0022]
When this first undulation conveyance path 21 falls to the inner end side of the main carry-in path 10, the conveyance path of the next workpiece W that has already been received and sent on the main carry-in path 10 is extended. In other words, along with the work for inserting the previous work W into the vertical rack 60, preparation for the insertion of the next work W is made.
[0023]
Next, if the workpiece W is completely inserted into the vertical rack 60 by the rotation of the roller shaft 22b constituting the second undulating conveyance path 22 and the conveyance roller 22d thereon, this time, The two undulating transport paths 22 will fall from the state shown in FIG. 6B to the state shown in FIG. As a result, a conveyance path by the second undulation conveyance path 22 is further formed on the inner end side of the main carry-in path 10 at the next stage of the first undulation conveyance path 21 that has fallen first, and the next workpiece W Is conveyed to a state where it can be erected immediately by the first undulating and conveying path 21 and the second undulating and conveying path 22.
[0024]
In the case of the undulating transport path 20 having the third undulating transport path 23 in the next stage of the second undulating transport path 22 as in the embodiment shown below, this third undulating transport path 23 is also described above. It operates in the same sequence as the second undulating transport path 22.
[0025]
As described above, both the first undulation conveyance path 21 and the second undulation conveyance path 22 that have been inserted into the vertical rack 60 and have been overlaid as shown in FIG. As described above, the next workpiece W is erected in the state shown in FIG. 6A, and the same is repeated thereafter. Of course, during this time, the vertical rack 60 is finely fed by the rack conveyance path 30 by the pitch of each vertical groove 61 and always waits for the workpiece W to be inserted into the next vertical groove 61. Needless to say.
[0026]
As described above, according to the receiver 100 of the first aspect, the undulating conveyance path 20 is configured while the workpiece W is inserted into the vertical rack 60 by the undulating conveyance path 20. Since the first undulating and conveying path 21 and the second undulating and conveying path 22 sequentially return to the front end side of the main carry-in path 10 and sequentially extend the main carry-in path 10 for the next work W, the previously received work When the insertion of W into the vertical rack 60 is completed, preparation for insertion of the workpiece W received next is completed. In other words, the insertion of the workpieces W into the vertical rack 60 by the receiver 100 is performed one after another without causing almost any time lag, and the insertion operation can be performed more efficiently than the receiver. 100 is going.
[0027]
Therefore, the receiver 100 according to the first aspect of the invention receives the work W that has been continuously sent in the horizontal state, and then inserts the work W in the upright rack 60 in a state in which the work W is erected. The receiving work time has been greatly shortened.
[0028]
In order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is as follows:
“A descending stage 40 that descends after receiving the bottom edge of the workpiece W at a position that is next to the second undulating conveyance path 22 and intersects the rack conveyance path 30, The bottom edge of the workpiece W that has been dropped in a standing state is received, and the workpiece W is prevented from being lowered into the bottom groove 62 of the vertical rack 60. "
It is.
[0029]
That is, in the receiver 100 according to the second aspect, even if the size of the workpiece W inserted into one vertical rack 60 is different as illustrated in FIG. Each workpiece W can be inserted in a stable state without giving an impact that causes the occurrence of the above.
[0030]
It is the lowering table 40 disposed below the undulating conveyance path 20 so that the insertion can be performed while exhibiting a stable and buffering function. It moves up and down through an opening 63 formed in the seat portion of the mold rack 60, and is moved by an upper and lower cylinder 41 via an arm 42 so that the position indicated by the phantom line in FIG. It will be moved up. Further, the descending table 40 descends to the bottom dead center indicated by the solid line in FIG. 4 and has the vertical rack 60 forward or slightly advanced.
[0031]
That is, when the descent base 40 is at its top dead center, it receives the bottom edge of the workpiece W inserted in the upright state by the above-described undulating conveyance path 20 and gently descends to the bottom dead center in that state. The bottom edge of each workpiece W is engaged with the bottom groove 62 on the vertical rack 60 immediately before the bottom dead center is reached.
[0032]
As a result, even if the size of each workpiece W is different, the bottom edge of each workpiece W is always stably engaged in the bottom groove 62 on the vertical rack 60 side. Even if each workpiece W having a different height is inserted into the vertical rack 60 in an upright state, the workpiece W is always inserted in a quiet and stable state. Together with this, as in the vertical rack 60 shown on the left side of FIG. 1, the work can be inserted without damaging each workpiece W.
[0033]
Therefore, the receiving device 100 of claim 2 performs the same function as that of claim 1 above, and can insert each workpiece W in a buffered state. It can be surely inserted into the vertical rack 60 without damaging it.
[0034]
