Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an inspection device for a mount conveying jig used in the manufacturing process of a light bulb mount.

(B) Prior Art In the manufacturing process of light bulb mounts, the filament coils are usually held in a mount conveying jig and processed one after another. As shown in FIGS. 5 to 7, such a mount transfer jig j has a main body a having a concave portion c opening at the top, and a pair of pin holes b extending through the concave portion c in the lower part thereof in the front and back directions.
is formed in the recess c, and a lever d that presses a pair of pins inserted into the pin hole b is rotatably mounted on a support shaft e, and the tip of the lever d is pushed down by a spring i. It is becoming more oppressive. When holding the filament coil for mounting with the mount transfer jig j, as shown in FIG.
Weld a filament coil f to the metal foil o.
The lead portion l of the wire is welded.

In the manufacturing process of mounts using the above-mentioned mount transport jig, conventionally the product was inspected while it was held in the mount transport jig and defective products were rejected. In some cases, the mounting and transporting jig is good but the product itself is defective, and the mounting and transporting jig is not good, resulting in defective products and being determined to be defective. Therefore, at best, the mount conveyance jig itself is excluded from the manufacturing process, which is inefficient.

(c) Problems to be solved by the present invention The problem to be solved by the present invention is to provide a method in which the quality of the mount transport jig 3 can be inspected in advance before the mount transport jig 3 holds the filament coil in the mount manufacturing process. It is to do so.

(d) Means for solving the problem The inspection device for the mount transfer jig according to the present invention has the following features:
A plurality of guide shafts are movably provided on the main body so as to move parallel to each other and simultaneously, and a driving member and an inspection block are mounted on the guide shafts so as to be movable relative to the guide shafts, respectively. and pressing the inspection block against one of the guide shafts,
An inspection pin that is inserted into the pin hole of the mount transfer jig is attached to the inspection block, and a claw that presses the lever of the mount transfer jig is rotatably provided on the main body. A detection device for detecting movement of the guide shaft and the inspection block is provided adjacently.

(e) Effect In the above configuration, when the mount conveyance jig is sent to the inspection position by the conveyance device, the guide shaft is moved relative to the main body by the drive member. Then, the inspection block is also moved, and the inspection pins are inserted into the holes of the mount conveyance jig to inspect the pin holes. When the test pin does not enter the pin hole smoothly, only the drive block moves and the guide shaft and test block are prevented from moving. Therefore, by detecting this, a defective pin hole is detected. Furthermore, when returning the drive block to its original position after the test pin enters the pin hole, if the pressing force of the lever of the mount conveyance jig is large, the movement of the test pin will be blocked and the test block will be temporarily blocked. , If the holding force is small, the inspection pin will move quickly. This is detected and the quality of the pressing force of the lever is inspected.

(F) Embodiments Examples of the present invention will be described below with reference to the drawings.

1 to 3, a mount transfer jig inspection apparatus (hereinafter simply referred to as an inspection apparatus) 1 according to the present embodiment is shown. This inspection device 1 includes a main body 2 attached to a vertically extending support shaft 10, and a pair of guide shafts 3 and 3a movably supported in parallel to each other by a pair of separated bearing parts 21 of the main body 2. , and an inspection block 4 movably mounted on the ends of the guide shafts 3 and 3a.
The guide shafts 3 and 3a are connected at both ends by connecting plates 31 and 32 so that they can move integrally with each other.

A pair of collars 33 and 34 are attached to one of the guide shafts 3 at a predetermined interval between the bearing portions 21, and a drive block 5 is attached between the collars so as to be movable with respect to the guide shaft 3. The drive block 5 is pressed against the collar 33 by a spring 51. The guide shaft 3a is adapted to move relative to the drive block 5. As shown in FIG. 2, a groove 52 is formed on the lower surface of the drive block, and the groove 52 receives a roller 55 attached to a known drive lever 54 rotatably attached to the support shaft 10. ing. Therefore, when the drive lever 54 reciprocates, the drive block 5 reciprocates.

The inspection block 4 is provided at the end of the guide shafts 3 and 3a on the side of the connecting plate 31, and is pressed against the side of the connecting plate 31 by a spring 37 provided between it and a collar 36 attached to the guide shaft 3a. . A pair of inspection pins 43 are attached to the lower surface of the inspection block 4 via attachment members 42 in parallel with each other at the same spacing as the spacing between the pin holes b of the mount conveyance jig j. These inspection pins 43 are parallel to the guide shafts 3, 3a and extend toward the main body 2 side.

In the main body 2, an operating lever 61 of a lever opening/closing mechanism 6, which is a jig for pressing the lever of the mount transfer jig j, is further rotatably attached to the lower side of the guide shafts 3, 3a by a shaft 62. One end of the operating lever 61 protrudes opposite the inspection pin 43, and an opening/closing claw 63 is rotatably attached to the tip of the operating lever 61 by a pin 64. The shaft 62 extends horizontally at substantially right angles to the support shaft 10, and the pin 64 extends vertically like the support shaft. Therefore, it can be rotated vertically about the shaft 62 and horizontally about the pin 64.

The opening/closing pawl 63 has an inverted L-shape in plan view, as shown in FIG. 3, and a tip 63a protrudes diagonally downward in elevation, as shown in FIG. 2. Rear end 63b of opening/closing claw 63 (Fig. 3)
A spring 65 is stretched between the control lever 61 and the operating lever 61, and is always kept under pressure in the state shown by the solid line in FIG. A stopper pin 66 is attached to the lower surface of the opening/closing claw 63.

A first optical sensor 71 of the detection device 7 is attached to the lower surface of the main body 2 on the side of the connecting plate 32 (on the right side in FIG. 1). This sensor 71 is used in combination with a blocking plate 72 attached downward to the lower surface of the collar 34, and the blocking plate 72 blocks a light receiving window (not shown) of the sensor 71, so that the collar 34 can be Therefore, it is detected that the guide shaft 3 has moved. The main body 2 further includes a second detection device.
An optical sensor 75 is attached via a mounting plate 76. Sensor 75 is connected to inspection block 4
A blocking plate 77 placed on the side of the test block 4 and attached to the test block 4 closes the light receiving window of the sensor 75, thereby making it possible to detect whether or not the test block has moved relative to the main body.

The above-mentioned inspection device 1 is disposed at the periphery A of a jig inspection turret provided adjacent to a jig intake conveyor 101 of a mount manufacturing line as shown in FIG. The mount conveyance jig supplied to the turret 102 is inspected. Note that 104 is a mount manufacturing turret, and 103 is a transfer device that transfers the mount transport jig from the jig inspection turret to the mount manufacturing turret 104.

Next, the operation of the apparatus of the above embodiment will be explained.

The mount conveying jig j supplied by the jig intake conveyor 101 is held in the periphery of the jig inspection turret 102 by a known method, and is sent to the inspection position A where it is stopped. This stop position is shown in Figures 1 and 2.
This is the position indicated by the chain line in the figure.

When the mount transfer jig (hereinafter simply jig) j stops at the inspection position, the rod end 67 connected to the end of the operating lever 61 of the opening/closing mechanism 6 is raised by a driving device such as a cylinder or cam mechanism (not shown). , the operating lever 61 is rotated counterclockwise in FIG. Then, the opening/closing pawl 63 rotates in the same direction around the shaft 62, and the tip 63a pushes the spring side of the lever d of the jig j to open it, and the stopper pin 66 moves to the rear of the jig (on the right side in Fig. 2). Descend. This is to prevent the jig j from moving backward when the inspection pin 43 is inserted into the pin hole of the jig j, as will be described later.

The drive lever 54 is then rotated clockwise in FIG. 2 by a drive device of known construction, such as a cylinder or cam mechanism. Then, since the drive block 5 moves to the right in FIGS. 1 and 2, the guide shafts 3 and 3a are also pushed by the spring 51 and move to the right.
Therefore, the connecting plate 31 hits the inspection block 4 and pushes the inspection block, and the inspection pin 43 is pushed into the pin hole b of the jig j waiting at the inspection position (if there is a defective mount, (It is inserted while pushing out the defective products.) In this case, since the guide shafts 3 and 3a move relative to the main body, the blocking plate 72 moves relative to the sensor 71 and blocks the light receiving window of the sensor, thereby detecting that the test pin has been inserted normally. do.

When the pin hole b is deformed or the like and the test pin cannot be inserted smoothly, the movement of the test block 4 and guide shafts 3 and 3a is obstructed, so only the drive block 5 is moved by the spring 5.
Compress and move 1. Therefore, the shielding plate cannot be moved and cannot block the light receiving window of the sensor 71.

Next, after the inspection pin is inserted normally, when the rod end 67 is lowered, the opening/closing claw 63 rises and releases the pressure on the lever d of the jig j, so that the lever presses the inspection pin 43 by the pressing force of the spring. Hold.
In this state, when the drive lever 54 is rotated counterclockwise in FIG. 2, the drive block 5 moves to the left in the figure and presses the collar 33. Therefore, the guide shafts 3, 3a move to the left in FIG.

When the pressing force of the lever d is sufficient, the inspection pin 43 is pressed by the lever d and movement is prevented.
As a result, the test block 4 is prevented from moving and cannot be moved until the spring 37 is compressed by a predetermined amount. Therefore, even if the driving block 5 moves a predetermined distance, the inspection block cannot move and the shielding plate 77 closes the sensor 75.
The light receiving window cannot be blocked. Detect this and lever d
Detects whether the pressing force is normal or not. In this case, the required pressing force can be detected by detecting how much the spring is compressed based on the distance traveled by the drive block. On the other hand, if the pressing force of the lever d is insufficient, the test pin and the test block also move at the same time as the drive block 5 moves, and the shielding plate 77 immediately closes the sensor 75 as shown in FIG. Block the light receiving window.

If the test pin does not come out even if the pressing force of the spring 37 exceeds a predetermined value, the end surface 38 of the collar 36
presses the inspection block and forcibly pulls it out.

The defective jig j is removed from the jig inspection turret at the next location by known means.

Furthermore, since the opening/closing claw 63 can be rotated in the horizontal direction to the state shown by the broken line in FIG. Accordingly, the opening/closing pawl can also be rotated against the spring to the state shown by the broken line above, thereby preventing damage to the jig or device.

(g) Effects According to the inspection device of the present invention, the quality of the mount transport jig can be automatically inspected before holding the mount, so defects are not discovered after welding the filament coil and metal foil, unlike in the conventional method. It is more efficient as it eliminates the inconvenience of
