Description

[Detailed description of the invention]

[Technical Field] The present invention relates to an autohandler, and particularly to a technique that is effective for use in a sorting device. [Background Art] For example, there is a handler as shown in FIG. (Electronic Materials 1981 Special Edition p226-p230) In the figure, the loader accumulates the objects to be measured stored in the magazine and supplies the objects to the environmental tank 2 by falling under their own weight. The environmental tank 2 stores the supplied object to be measured depending on the purpose of measurement.
The sample is transported to the measuring section 3 by gravity drop while being subjected to low temperature or high temperature treatment or kept at room temperature. The measuring section 3 measures the transported object to be measured using a contact or socket method, and is connected to a tester 8 located outside the apparatus by a connecting wire 9. The sorting section 4 sorts by a gravity drop method and a sorting mechanism according to the measurement results. The unloader 5 collects the selected objects to be measured into magazines according to their classification using a gravity drop method, and then stores the objects together in the magazines.
The control unit 6 controls each of the above operations.
The operation unit 7 is used to operate each of the above operations. The inventor has revealed that the handler with the above configuration has the following problems. In other words, due to the large size of the device, the amount of magazines stored in the loader 1 and unloader 5 is limited due to the operability when loading objects to be measured stored in the magazines into the loader 1, or due to the structure of the device. It is limited in terms of In addition, the object to be measured may become jammed during transportation, or the object to be measured may become jammed, especially if the object is a dual-in-line glass-sealed or dual-in-line laminated ceramic package. There have been problems such as damage to the measured object such as cracks and chips due to collision between the measured object and the stopper.
However, when making a device smaller in order to improve space efficiency, for example to make it smaller in the vertical direction, it is necessary to reduce the accumulated amount of magazines (vertical loading amount) in the loader and unloader, or to reduce the transport mechanism of each part of the device. It is conceivable to install it so that it is close to horizontal to the installation surface. On the other hand, to make the size smaller in the lateral direction, it is possible to make the loader and unloader smaller by shortening the environmental tank, sorting section, and unloader, or by shortening the length of the magazine and reducing the amount of objects to be measured. Conceivable. However, the above method cannot be used when considering the accumulation amount of loaders and unloaders from the viewpoint of unmanned operation efficiency, production efficiency, and jam occurrence rate. Furthermore, if the capacity of the loader and unloader is increased by simply increasing the size of the loader and unloader, the size of the device will further increase. As for jams, since the object to be measured is not mechanically conveyed, it is difficult to prevent jams. As mentioned above, there are many seemingly unreasonable points, making it extremely difficult to solve these kinds of problems. Therefore, the inventor of the present invention has proposed that the object to be measured transport mechanism, which is the basic structure of the handler, is provided diagonally to the installation surface of the device, that is, the object to be measured is transported using a self-weight drop method. Focusing on the
We tried to solve various problems. [Object of the Invention] An object of the present invention is to provide a handler capable of testing objects to be measured under various environmental settings with a compact device configuration. Another object of the present invention is to provide a handler that can easily increase the capacity of loaders and unloaders. Still another object of the present invention is to provide a handler that can reliably prevent jamming of an object to be measured on its moving path and damage to the object. The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Summary of the Invention] A brief overview of typical inventions disclosed in this application is as follows. That is, the handler of the present invention includes: a loader that is installed horizontally with respect to the device installation surface and stores a plurality of magazines in which a plurality of objects to be measured are stored in a row in the longitudinal direction in a stacked manner; arranged parallel to and integrally with
an environmental tank in which the object to be measured supplied from the loader is subjected to processing according to the purpose of measurement while moving along a horizontal path directly under the loader; A measuring and sorting section that measures and sorts the processed objects to be measured; and a magazine that is arranged parallel and integrally with the environmental tank and that stores the objects taken out from the measuring and sorting section horizontally just below the environmental tank. an unloader that collects the object within the loader, and a tape measure-type first forced feeding mechanism that is placed at one end of the magazine located at the lowest end within the loader and forcibly moves the object to be measured in the magazine horizontally to the other end. and a rail on which the objects to be measured discharged to the other end of the magazine by the first forced feeding mechanism are individually placed, and a vertical movement for raising and lowering the rail to the height of the environmental tank. A second forced feeding mechanism consisting of a rotating screw and a feed claw that forcibly feeds the object to be measured on the rail into the environmental chamber in the horizontal direction; and a second forced feeding mechanism that is installed in the measurement sorting section and distributes the measured objects. A third forced-feeding mechanism includes a swinging arm that performs this and a pusher that forcibly feeds the object to be measured on the swinging arm horizontally into the magazine in the unloader, and a wall surface of an environmental tank between the loader and the unloader. and a magazine conveyance section that conveys the magazine in the loader to the unloader using a pair of elastic belts that are arranged along the magazine and convey the magazine while holding it in a horizontal position. As a result, the loader, environmental tank, and unloader are arranged so as to be stacked together on the equipment installation surface, and the conveyance of the object to be measured from the loader to the unloader is carried out by the first, second, and third forced feeds. Since the mechanism allows testing to be carried out horizontally to the equipment installation surface, it is possible to test objects to be measured under various environmental settings with a compact equipment configuration.
By effectively utilizing the installation space, it is possible to easily increase the capacity of magazines in loaders and unloaders. Furthermore, since the object to be measured from the loader to the unloader is forcibly transported by the first, second, and third forced feeding mechanisms, damage caused by collisions with the jam and the object to be measured can be prevented. can. [Embodiment] FIG. 2 is a front view showing a handler that is an embodiment of the present invention.

It has the function to Next, details of each part of the handler having the above configuration will be explained. A Loader 10 FIG. 3 is a detailed view of the loader 10, particularly showing a mechanism for taking out magazines 19 containing objects to be measured one by one in each row. That is, the lower claw 20 of the two claws 20 and 21 provided at both ends of the magazine 19 in the longitudinal direction are arranged in parallel with the longitudinal direction of the magazine 19 in each row.
Among the stacked magazines 19, the recessed portion of the lowest one is hooked, and the magazines 19 stacked in a plurality of rows are held. The claws 20 and 21 are configured to alternately slide by rotation of cams 23 and 24 provided on the rotating shaft of the rotating shaft 22, respectively. This operation occurs as the rotating shaft 22 rotates and the cam 2
The rotation of the cam 24 causes the claw 20 to move backward, while the rotation of the cam 24 causes the claw 21 to protrude, catch the recess of the magazine 19 located second from the bottom, and hold the magazine 19 above it. After that, when the claw 20 is sufficiently retreated, the magazine 19 at the bottom, which has been hooked by the claw 20, falls. Further rotation of the rotating shaft 22 causes the claw 21 to move backward, while the claw 20 protrudes, and when the claw 20 is fully protruded, the claw 21 is released, and the upper and lower parts that were previously supported by the claw 21 are released. A certain magazine 19 falls and is held by the claw 20. Further, rotating shafts 25, which are provided below both longitudinal ends of the magazine 19 in the front of the supplied magazines 19 and arranged in a direction perpendicular to the longitudinal direction of the magazine 19, each have one end attached to a bearing 2.

As this rotating shaft 25 rotates, the cam 28 provided on the rotating shaft 25 rotates, and the clampers 29 provided at both ends of the magazine 19 in the longitudinal direction move, clamping the magazine 19 in front at both ends in the longitudinal direction. do. Thereafter, as shown in FIG. 4, the magazine 1 is pushed out by the tape measure type forced feeding mechanism 11
The objects to be measured in 9 are sent out one by one. When all of the objects to be measured in the magazine 19 are sent out, the extrusion mechanism of the forced feeding mechanism 11 returns to its original state, the clamper 29 is released, and the magazine 19 is sent to the magazine transport section 13. Thereafter, among the magazines 19 supplied in multiple rows, the magazine 19 in the second row from the front is conveyed to the front by the rectangular movement of claws (not shown) provided at both ends of the magazine 19 in the longitudinal direction, and is transported to a predetermined position. When this point is reached, the object to be measured is clamped by the clamper 29, and the object to be measured is supplied in the same manner as described above. Thereafter, the magazines 19 are sequentially supplied, and when the magazines 19 supplied in the plurality of rows are exhausted, the claws 20 and 21 slide in the same manner as described above, and the magazines 19 in the plurality of rows are supplied one by one. Note that each of the rotating shafts 22 is supported by a bearing (not shown) at one end in the longitudinal direction, and the other end is connected to the bevel gear 27 by a rotational drive shaft (not shown). They are connected by having the same shape (not shown). Further, a reference numeral 30 of the clamper 29, which is provided in a direction perpendicular to the longitudinal direction of the magazine, serves as a fulcrum shaft of the clamper 29, and the clamper 29 swings about this fulcrum shaft 30 as a fulcrum. Further, the rotating shaft 31, which is installed parallel to the longitudinal direction of the magazine, is supported at one longitudinal end by a bearing (not shown), and the other end is connected to a rotating mechanism (not shown). In order to rotate the rotating shaft 25, it is connected to the bevel gear 32 which is the same as the bevel gear 27. B Conveyance Section 12 FIG. 5 shows the object conveyance mechanism (second forced feeding mechanism) in the conveyance section 12. That is, 33 is a rotating screw for vertical movement, and its longitudinal direction is arranged perpendicular to the device installation surface, and one end is supported by a bearing 34.
The other end is connected to a drive source (not shown). The vertically movable screw 35, which moves vertically by the rotation of the vertically movable rotary screw 33, is provided with a rail 36 for conveying the object to be measured in the same direction as the longitudinal direction of the magazine 19. In this operation, the objects to be measured, which are sent one by one from the loader 10, are transferred one by one to the rail 3.
6, the vertically moving rotary screw 33 rotates, and the vertically moving screw 35 lowers to convey it to the front of the entrance of the environmental tank 14, and insert it into the environmental tank 14 using the feed claw 37. Thereafter, the vertical screw 35 is raised by rotating the vertical screw 33 in the opposite direction, and after stopping at a predetermined position, the same operation as described above is repeated to transport the object to be measured.

The operation is such that the robot arms 47 and 48 move along the two guide rails 49 to the support block 50 so that they are located at a predetermined position above the object to be measured in front of the exit of the environmental tank 14 and at a predetermined position above the socket 51, respectively. moves. Thereafter, the robot arms 47 and 48 descend, gripping the object to be measured and the already measured object with their clamping portions, respectively, and the robot arm 47 and 48 move up and are pulled out from the socket 51. When the support block 50 rises to a predetermined height, it begins to move rightward in the figure along the two guide rails 49. Then, as shown in FIG. 10, the robot arm 47 connects to the socket 5.
When the robot arm 48 reaches a predetermined position above the rail 54, it stops. Thereafter, the robot arm 47 descends and inserts the object to be measured into the socket 51. Meanwhile, the robot arm 48 also descends and places the measured object on the rail 54. Thereafter, the measured object is conveyed along the rail 54 to the front side of the sorting mechanism by the rectangular movement of the feed claw 55. FIG. 11 shows the socket 51 of the measurement selection section 15.
The sorting mechanism (third forced feeding mechanism) provided below is shown. In the figure, reference numeral 56 denotes a swinging arm, which swings around a rotating shaft 57. As shown by the two-dot chain line in the figure, when this swinging arm 56 rotates to the front of the magazine 19, the part on which the measured object is placed is 90 degrees with respect to the longitudinal direction of the swinging arm 56. It rotates so that the longitudinal direction of the magazine 19 and the longitudinal direction of the measured object coincide. 58 is a feed claw capable of rectangular movement, and has the role of conveying the measured object onto the swing arm 56. 5

In this operation, the measured object is conveyed onto the swing arm 56 by the claw 58. Then, based on the measurement results, the swing arm 5
6 rotates, and the measured object is collected into the magazine 19 by the pusher 59. F Unloader 18 In the unloader 18, after collecting the selected and measured objects into the magazine 19,
It has the function of accumulating data. FIG. 12 shows a mechanism for mounting a magazine 19 filled with measured objects onto an elevator. In the figure, 61 is perpendicular to the longitudinal direction of the magazine 19,
These swing arms are provided at both ends of the magazine 19 in the longitudinal direction, have the function of transporting the magazine 19, and swing around the rotating shaft 62. A rotation guide plate 63 is provided at the tip of this swing arm, and has the function of holding the magazine 19 and guiding and conveying the magazine 19 by rotating. Reference numeral 64 denotes a guide plate that guides the conveyance of the magazine 19. 65 is an elevator, which descends after loading multiple rows of magazines 19,
It has the function of mounting magazines 19 in multiple stages above it. 66 is a container. The operation is such that the swinging arm 61 holding the magazine 19 filled with measured objects rotates around the rotation axis 62 as shown in the figure, and then the rotation guide plate 63 rotates 90 degrees. The magazine 19 rotates and falls on the rotation guide plate 63. Then, the falling is temporarily stopped by the guide plate 64, and as shown in FIG.
3 rotates, the magazine 19 falls along the guide plate 64. Thereafter, when the rotation guide plate 63 rotates 180°, as shown in FIG. 14, the rotation guide plate 63 is pushed out by rotation and is mounted on the elevator 65. After repeating this operation and loading multiple rows of magazines 19, the elevator 65 descends and the magazines 19 are loaded thereon. after that,
The magazines 19 are stored in the container 66. Note that this accumulation mechanism is performed for each classification. Next, the flow of the object to be measured will be explained. The objects to be measured accumulated in the loader 10 are transported one by one to a transport section 12 by a tape measure-type forced feeding mechanism 11 . In the transport section 12, the pieces are transported one by one to an environmental tank 14, and then subjected to low temperature or high temperature treatment depending on the purpose of measurement in the environmental tank 14.
Alternatively, it is kept at room temperature and transported to the front of the measuring and sorting section 15 by the rectangular movement of the block 46. In the measurement and selection section 15, the robot arm 47 inserts the sample into the socket 51 and measures it. When the measurement is completed, the robot arm 48 extracts the sample and transports it. Thereafter, they are sorted by a sorting mechanism based on the measurement results, collected into magazines 19 by category by an unloader 18, and stored together with the magazines 19 in a container 66. [Effects] 1 The forced feeding method (first,
By mounting the loader, environmental tank, and unloader horizontally on the equipment installation surface using the second and third forced feeding mechanisms), the entire equipment becomes smaller. , the effect of improving space efficiency can be obtained. 2. The forced feeding method (first,
The second and third forced feed mechanisms) are used to move horizontally to the equipment installation surface, and the loader, environmental tank, and unloader are mounted horizontally on top of each other to the equipment installation surface, making the entire equipment smaller. As a result, the efficiency of supplying magazines filled with objects to be measured in the loader and collecting the measured objects in the unloader can be improved. 3. The forced feeding method (first,
The second and third forced feed mechanisms) are used to move horizontally to the equipment installation surface, and the loader, environmental tank, and unloader are mounted horizontally on top of each other to the equipment installation surface, making the entire equipment smaller. As a result, it is possible to easily increase the capacity of the loader and unloader. 4 Forced feeding method (first,

This has the effect of preventing damage to the 6 The capacity of the loader and unloader can be increased, and damage to jams and objects to be measured can be prevented, resulting in a synergistic effect of increasing the amount of objects to be measured, reducing the need for manpower, and improving the efficiency of unmanned operation. can get. Although the invention made by the present inventor has been specifically explained based on the examples above, the present invention is not limited to the above examples, and it is understood that various changes can be made without departing from the gist of the invention. Needless to say. For example, in a loader, the operation of the claw slide mechanism and the magazine clamp mechanism are
This can be done with one cam for one longitudinal end of the magazine, which simplifies the mechanism. Further, the clamp mechanisms may be provided at both ends of the magazine in the longitudinal direction and sandwich the magazine orthogonally to the longitudinal direction. This improves space efficiency in the upward direction. In addition, for magazines with openings in the longitudinal direction, there is also a method of inserting a tab along the opening and using the tab to transport the object to be measured.
By doing so, there is no need to provide a transport mechanism outside the loader, and the number of protrusions on the loader is reduced. In the conveyance section, there is a method in which the object to be measured is conveyed to the front of the entrance of the environmental tank by vertical movement of a lever by rotation of a cam, which simplifies the mechanism. In the magazine transport section, the magazine can be transported after all the objects to be measured have been supplied by the loader by vertically swinging the swinging arm or by vertically moving the link mechanism. By doing so, the mechanism can be simplified. In an environmental tank, there are two methods: one is to transport the object to be measured by rectangular movement of a guide block, and the other is to place the object to be measured on a block extending in the longitudinal direction and feed the object by claws. This improves the efficiency of low- and high-temperature processing. There is also a method of arranging the objects to be measured so that the longitudinal direction thereof is perpendicular to the longitudinal direction of the magazine and transporting them by rectangular movement of the blocks.By doing so, it is possible to process and transport a large number of objects to be measured. In that case, the object to be measured is rotated by 90° while being transported by the transport section. Also,
A shutter may be provided at the entrance and exit of the environmental tank, or a plurality of partition plates may be provided within the environmental tank, thereby making it easier to maintain low and high temperature conditions within the environmental tank. There is also a method of measuring using a plurality of sockets in the measurement and selection section, which allows efficient measurement. Additionally, the socket position can be placed perpendicular to the device installation surface.
By doing so, the measuring and selecting section can be made compact. Other methods include a method in which sorting is performed using a rail that can swing in the longitudinal direction of the object to be measured;
There is also a method using a rail movable in a direction perpendicular to the longitudinal direction of the object to be measured, and the sorting mechanism can be selected depending on the number of classifications and space. Also,
The object to be measured can also be collected into the magazine using a claw. In an unloader, there is a method in which a magazine filled with selected and measured objects is loaded onto an elevator using a single swinging arm installed at the longitudinal center of the magazine.
This simplifies the mechanism. Also,
There is also a method of accumulating magazines containing defective products by dropping them under their own weight, which simplifies the mechanism. [Field of Application] In the above explanation, the invention made by the present inventor was mainly applied to the field of application of semiconductor devices, which is the background of the invention, but the present invention is not limited thereto. for example,
It can be applied to handlers for electronic components other than semiconductor devices such as image pickup devices, or small articles.
