Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to an electronic component conveying device used in the painting, drying process, etc. of cylindrical chip-shaped electronic components.

(Prior Art) In recent years, electronic components called cylindrical chip components that do not have lead wires have appeared. This type of electronic component cannot be subjected to various manufacturing processes while supporting lead wires, unlike components with leads.

Therefore, when transporting the above-mentioned electronic components, a belt is provided to fit and transport the electronic components, as shown in the transport device described in Japanese Utility Model Application Publication No. 50-104506, and a belt is provided below the belt to transport the electronic components. A structure is adopted in which the pedestal is provided with rails that support and guide the electronic components being transported during manufacture.

In addition, when this conveyance device has a process that involves heating, such as a drying process for drying a film applied to an electronic component, the rails undergo significant thermal expansion or contraction in the direction of conveyance of the electronic component, so the next processing When connecting in the length direction to the rail of a conveying device equipped with a process, it was not possible to connect directly.

Therefore, as shown in FIG.
The electronic component A, which has been moved on the rail 1 by being engaged with the conveyor belt 3 running parallel to the rail 1, is attracted to the magnet 2, etc., and is conveyed through the gap S. An electronic component transport device has been proposed.

(Problem to be solved by the invention) However, the gap S of the conveying device shown in FIG.
When electronic component A is transported while being attracted by a magnet, electronic component A may become magnetized. Therefore, in the next process, the magnetism of electronic component A may cause trouble, and this magnetism may also cause physical defects such as adhesion, clogging, and falling off of metal powder, which may cause the most trouble. This was a major factor.

This invention was created in view of the above problems.
An object of the present invention is to provide an electronic component transport device that smoothly transports electronic components by eliminating gaps between rail joints.

[Structure of the idea]

(Means for Solving the Problems) The electronic component transport device of the present invention includes: a rail that guides the electronic component to be transported; a connected rail that is connected to the rail in the transport direction of the electronic component; The electronic component processing table is fixed and slidably provided in the transport direction of the electronic component.

(Function) The electronic component transport device of the present invention includes a rail that guides the electronic component to be transported, a connected rail that is connected to the rail in the transport direction of the electronic component, and a connected rail that is fixed to the rail and transports the electronic component. When the connected rail expands and contracts in the electronic component transport direction due to heat, the expansion and contraction of the connected rail is transmitted to the rail, and this rail The electronic component processing table to which is fixed is slid in the direction of conveyance of the electronic component depending on the degree of expansion and contraction of the connected rail. Therefore, the sliding movement of the electronic component processing table absorbs the expansion and contraction of the connected rail due to heat, so the rail and the connected rail can be connected without creating a gap at the joint, and the connection between the rail and the connected rail is reduced. Electronic parts can be transferred smoothly. Therefore, a plurality of electronic component transport devices can be connected without gaps in the electronic component transport direction.

(Example) An example of the electronic component conveying device of the present invention is shown in the first example.
This will be explained based on FIGS. 3 to 3.

In FIG. 1, reference numeral 4 denotes an electronic component processing table, which includes, for example, an electronic component feeder 5, and a rail 6 is fixed onto the processing table 4. As shown in FIG. A conveyor-like conveyor belt 7 is placed along the rail 6 at a small interval, and as shown in FIGS. 2 and 3, the rail 6 is Step portions 15, 15 on which the electrode portions of the electronic component A are supported are formed on both sides of the groove 14 formed in the portion.

The conveyor belt 7 is also formed with a large number of through holes 8 into which the electronic components A are fitted, and on both sides of the through holes 8 are notches 9 into which the electrodes at both ends of the electronic component A are engaged. , 9 are formed.

Then, the electronic components A supplied one by one from the electronic component supply machine 5 are fitted into the through holes 8 of the conveyor belt 7, and both ends of the electronic components A are fitted into the notches 9,
9, and as the conveyor belt 7 advances, the electrode portion of the electronic component A is conveyed while rolling on the stepped portions 15, 15 of the rail 6.

Further, reference numeral 11 denotes a connected rail, and this connected rail 11 is configured to have the same shape as the rail 6. One end of this connected rail 11 is
It is inserted into a guide groove 10 opened at the end of the processing table 4 and closely connected to the longitudinal end of the rail 6 without any gaps.

Further, the electronic component processing table 4 includes a fixed table 12
It is disposed above via a sliding body 13 such as a bearing, and is supported so as to be slidable in a direction parallel to the length direction of the rail 6, which is the direction in which the electronic component A is transported.

Next, the operation of this embodiment will be explained.

The electronic components A fed onto the conveyor belt 7 by the electronic component feeder 5 are fitted into the through holes 8 of this belt 7, and as the conveyor belt 7 advances, they are sequentially guided to the rails 6. It advances while rolling on the rail 7. Then, the electronic component A is transported to the conveyor belt 7
While still fitted to the rail 7, it moves onto the connected rail 11 connected to this rail 6, and progresses while rolling on this connected rail 11, to the painting process and drying process. will be sent sequentially.

When the electronic component A moving on the connected rail 11 is dried, for example, in a drying oven (not shown) to dry the coating film applied to the electronic component A, the connected rail 11 is dried by the heat in the drying oven. When expanded and contracted in the length direction, since the connected rail 11 is closely connected to the rail 6, the expansion and contraction of the connected rail 11 is transmitted to the rail 6 on the processing table 4. Then, the processing table 4 to which this rail 6 is fixed
is connected to this connected rail 11 via the sliding body 13.
It slides in the length direction of the rail 6 according to the degree of expansion and contraction of the connected rail 11, and absorbs the expansion and contraction of the connected rail 11.

Therefore, in preparation for thermal expansion of the connected rail 11,
It is no longer necessary to open a certain gap at the joint between the rail 6 and the rail 11 to be connected, and the rail 1 and the rail 11 to be connected can be connected continuously.

Therefore, from the rail 6 to the connected rail 11,
Electronic component A can be transferred smoothly without using a magnet, and electronic component A can be transferred smoothly without using a magnet.
can be prevented from occurring.

Furthermore, in the manufacturing process of the electronic component A, even if each electronic component processing table 4 is equipped with a processing process that uses heat, each electronic component processing table 4 has a joint between the respective rails 6 in the longitudinal direction. You can connect them simply by connecting them consecutively. For this reason,
The electronic component A is attached and detached from the conveyor belt 7 for each processing step of the electronic component A, and the electronic component A is carried between each electronic component processing table 4, and the electronic component A is supplied to each electronic component processing table 4. There is no need to provide a machine 5. Then, the electronic component A is transferred to the conveyor belt 7.
By simply supplying the electronic component A to the top once, the electronic component A can be transported to each processing step for manufacturing the electronic component A, and the manufacturing steps for the electronic component A can be serialized. Therefore, the productivity of the electronic component A can be improved, the yield can be increased, and the manufacturing cost of the electronic component A can be reduced.

Note that the above embodiment is applicable not only to the connection between the rail 6 and the connected rail 11 but also to the connection between the connected rail 11 and the connected rail 11, so that the connected rail 11 and the connected rail 11 can be connected without any gap. Can be connected.

Therefore, when the connected rail expands and contracts in the length direction of the electronic component transport direction due to heat, etc., the expansion and contraction of the connected rail is transmitted to the rail on the processing table. It is possible to absorb the expansion and contraction of the connected rail by sliding in the length direction of the rail via the sliding body according to the degree of expansion and contraction of the connected rail. Therefore, the rail and the rail to be connected can be connected continuously without creating a gap at the joint, and electronic components can be smoothly transferred between this rail and the rail to be connected. can be transported to
