Field of the Invention The present invention relates to an automatic terminal staking apparatus, and more particularly to a terminal staking apparatus which automatically conducts a series of operations of supplying, holding, staking and removing the terminal parts from the apparatus. The apparatus of the present invention is used as a staking machine in a mass production factory and the like.

2. Description of the Prior Art In accordance with the usual techniques practiced heretofore, as shown in FIG. 1 several terminals 2 have been manually staked to a base plate 1 resulting in the manufacture of a finished product as shown in FIG. 2. In this case, the terminals 2'are inserted one by one'into the fixing holes 3 of the base plate 1, and then the terminals 2 as illustrated in FIGS. 3A-3B are pressed against the edge portions 6 of the staking tools with a press member 4 so that a portion'of the terminals 2 may be staked. Thus, the terminals 2 are staked to the base plate 1. The above described manual caulking operation is disadvantageous in that an excessive amount of labor and time are required to assemble the terminals 2 with the base plate 1. Also, it is dangerous to use a press member for each staking operation. Another disadvantage inherent in the manual staking operation is that quality control in the assembling process cannot be easily conducted. That is, the accuracy in the assembling operation is difficult to maintain witha high degree of uniformity.

Further, although some special jigs have been devised to improve the efficiency of this staking operation, each operation of the removal of parts can not help depending on manual operation.

Still further, though there has been an intermittent feeding system for feeding jigs intermittently on a horizontal plane in cycle by the use of barrel cams, this system is disadvantageous in that the angle measurement and setting thereof for the location of various processing machines arranged along the circle of feed are difficult to obtain. In this case, for instance, the various machines are the supplying device, pressing device, removal device and so forth. Further, it has been known in the art to feed the jigs intermittently on a horizontal plane by guiding the jigs along a rectangular groove and pushing them with oil cylinders of air cylinders. However, this method is also disadvantageous in that the pushing speed is varied by variation in pressure of the operating fluid and unstable variation in speed and impulsion cannot be avoided.

In the general part supplying device, it has been known to use a hopper in which a number of parts are stored in pile with the lowermost parts being pushed out successively. A difficulty encountered in this hopper type supplying device is that the supplying direction of the parts is limited. That is, in the case in which plate-shaped parts are to be supplied into a prescribed station in a vertical position, the parts pushed out from the hopper in a horizontal position, should be vertically oriented before being carried to the station. Otherwise, the hopper should be laid horizontally and a force should be sidewardly exerted to the parts stored in the hopper so that the parts may be pushed out from the hopper in a vertical position.

SUMMARY OF THE INVENTION In accordance with the present invention, a completely novel terminal staking apparatus is provided for replacing the above conventional assembling system. The apparatus in accordance with the present invention comprises jigs designed for desired parts, supplying devices for supplying parts to the jigs, and a jig intermittent feeding device for feeding the jigs intermittently according to the staking processes. The efficiency of production is increased 10 times by the present invention as compared with the prior art. Further, since the respective operations are interconnected with each other through cams and levers, the operation can be conducted quickly, securely and smoothly.

The first object of the present invention is to provide a terminal staking apparatus which operates securely and quickly for feeding, holding, staking and removing parts automatically.

The second object of the present invention is to provide a terminal staking apparatus in which the jigs employed in the apparatus are produced with high accuracy and high efficiency.

The third object of the present invention is to provide a terminal staking apparatus in which the jigs are intermittently fed, cyclically and securely, by the use of cam and lever systems.

The fourth object of the present invention is to provide a terminal staking apparatus in which the parts are smoothly supplied to and securely held by the jigs.

DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the apparatus for assembling the terminals with the base plate in accordance with the present invention will be described now with reference to the drawings.

As shown in FIG. 5, six

jigs

8, 9, 10, ll, 12 and 13 (hereinafter described) are made to move in cycle in the direction indicated by the arrows A, B, C and D on a jig sliding board 7. At the position (b), base plates 1 successively fed by the parts feeder X are inserted into the jigs 9 by a base supplying device 14. This base supplying device 14 (hereinafter described) is operated by a cam and lever driving system and supplies the base plates 1, one-by-one, to the jig 9.

At the positions (c) and (d), the terminals 2 as shown in FIG. 1 are coercively and successively fed out by the parts feeders Y and Z respectively in three rows and inserted into the fixing holes 3 of the base plate 1 which has been held by the jig 10. The terminals 2 are inserted into the holes 3 by the terminal supplying devices 15 and 16.

At the position (e), the terminals 2 (six in total) inserted in the fixing holes 3 of the base plate 1 are held by the jig l l and staked to the base plate 1 by a staking device 17' driven by an oil cylinder. The

jigs

9, 10, 11 and 12 located at the positions (b), (c), (d) and (e) respectively are simultaneously subjected to the operation of the above

respective devices

14, 15, 16 and 17 immediately after regulation of its position by a position regulator 18.

The

jigs

9, 10, 11 and 12 are released from the position regulator 18 after the operation of the devices, and released on the jig sliding board 7 along the guide thereon. Immediately thereafter, the

jigs

9, 10, 11 and 12 located at the positions of (b), (c), (d) and (e) are moved to the subsequent process positions by the longitudinal feeding rod 19 which pushes a jig 8 located at the position (a) in the direction A.

At the position (f), whenthe jig 12 which holds a finished product shown in FIG. 2 (hereinafter referred to as product) is pushed forward by the

adjacent jigs

11, 10, 9 and 8, the lateral feeding rod 20 pushes the jig 12 to the position (g) in the direction B as shown in FIG. 5.

Then the product is ejected out of the jig 13 by an ejection device 21 operated by a cam and lever mechanism and sent to the products feeding conveyer (not shown) by a product receiver 22.

Immediately after the products are ejected out of the jig 13, a quick feed conveyer 23 starts to run and feeds the jig 13 which holds no part to the position (b) in the direction C. After the quick feed conveyer 23 stops, the jig is pushed to the initial position (a) by the lateral feeding rod of jig returning rod 24 in the direction D.

In the construction above described, the position regulator 18, base plate supplying device 14, terminal supplying devices 15 and 16, jig longitudinal feeding rod l9,jig lateral feeding rod 20,jig returning rod 24, product ejection device 21 and a product receiver 22 are all interconnected through cams and levers so that they may be operated in relation to each other. Thus, the jig 8 at the position (a) moves along the process passage where the base plate is inserted thereinto, the terminals are inserted into the upper fixing holes, the terminals are inserted into the lower fixing holes, the terminals are staked to the base plate and so on as shown in FIGS. 4A-4D, and finally the jig returns to the initial position (a). By repeating this cycle of jig movement fully automatically and regularly, a large number of terminals can be assembled with the base plates to produce terminal parts with uniform accuracy in a short time.

In accordance with the present invention as described above, there are provided various advantages as follows:

First, since the staking process is completed fully automatically, the number of workers required can be reduced.

Second, the efficiency of operation is remarkably improved, which results in lower cost of the products.

Third, the products can be assembled with uniform accuracy.

Fourth, no matter how many terminals may be assembled, the staking operation can be conducted at the same time.

An embodiment of the jig used in accordance with the present invention will be described now, referring to FIGS. 7A, 7B, 8, 9, 10, 11A-11B.

On the upper face of the jig body portion 25 which is made of cast iron and the like, is secured a pallet 26 with guide pins 27. The pallet 26 is provided with a recess 28 at the center thereof in which a base plate 1 is fitted. The recess 28 is provided with an aperture 29 at the central portion thereof.

Further, this pallet 26 is secured to the guide pins by pins 30. As shown in FIG. 8, a spring 32 is mounted around the guide pin 27 in the hole 31 provided in the jig body portion 25. The springs 32 work to keep the pallet 26 at a position slightly spaced from the jig body portion 25. It will be noted that the guide pins 27 have head portions 33 to retain the guide pins 27 in the jig body portion 25. Further, the guide pins 27 are made to be moved up and down with respect to the jig body 25.

In addition, on the upper face of the jig body portion 25 are secured a plurality of staking tools 34 having a sharp or M-shaped tip end. The staking tools 34 are located at the position corresponding to the aperture 29 and have a length equal to the width of the aperture 29.

Between the staking tools 34, terminal guide rods 36 which have a concave receiving portion 35 at the top end thereof are provided so that they slide between the staking tools 34 and through the fixing holes 3 of the base plates 1. The number of the terminal guide rods 36 is equal to that of the fixing holes 3.

That is, the terminal guide rods 36 are fitted in the slots 37 provided in the jig body portion 25 with a proper friction fit.

Now the staking process to stake the terminals 2 to the base plate 1 by the use of the terminal staking jigs will be described in detail referring to FIGS. llA-l 16. First, as shown in FIG. 11A, the terminal guide rods 36 are pushed upward and ejected above the aperture 29 of the pallet 26. It will be noted that the pallet 26 is spaced from the jig body portion 25 by means of the springs 32, at this first stage.

At this stage, a base plate 1 is brought into engagement with the recessed portion 28 of the pallet 26 through a shoot manually, or by the use of a base plate supplying device 14 at the position (b) as shown in FIG. 5. At this moment, the terminal guide rods 36 are inserted into the fixing holes 3 of the base plate 1 and serve as a guide member to make the base plate fit in the recessed portion 28 with accuracy. Further, those terminal guide rods '36 work to prevent slippage of the base plate 1 due to vibration or the like while the jig is moved to the subsequent process station.

Subsequent to the fitting of the base plate 1 to the pallet 26, the terminals 2 are supplied to the base plate 1 by the use of terminal supplying devices and 16 as shown in FIGS. 9 and 11B. In this process, the terminals 2 are pushed into the fixing holes 3 of the base plate 1 by means of push rods 38 with the top end of the terminals abutting on the concave receiving portion 35 of the terminal guide rods 36. Then, at the time when the terminals 2 are completely inserted into the fixing holes 3 of the base plate 1 as shown in FIG. 11C, the push rods 38 of the terminal supplying device 15 or 16 are retracted from the extended position.

Further, subsequent to the above insertion process of the terminals 2, a press block 39 (provided in the pressing device 17 located at the position (e) in FIG. 5) energized with compressed air or oil pressure, is brought into the operating position as shown in FIG. 10 and presses the end of the terminals 2 as shown in FIG. 11D to move the pallet 26 toward the jig body 25. By this pressing operation, the pallet 26 is moved to the jig body compressing the springs 32 and contacting a portion of the terminals 2 in the holes 3 of the base plate 1 with the tip end of the staking edges 34 in the jig body 25. As the press block 39 presses the terminals 2, the sharp ends of the staking tools 34 are thrust into the portion of the terminals 2. Thus, the portion of the terminals 2 is staked to the base plate 1 as shown in FIG. 11E.

When the press block 39 is retracted thereafter, the pallet 26 is moved to its initial position by the spring force of the compression springs 32 and is maintained in its normal position spaced from the jig body 25.

Subsequent to the above process when the press block is retracted, the terminal guide rods 36 are again extended out to push the terminals 2 fixed to the base plate 1 out of the recessed portion 28 of the pallet 26 as shown in FIG. 11G. Thus, the whole process of staking terminals 2 to the base plate 1 is finished.

Alternatively, the terminal guide rods 36 employed in the above embodiment may be replaced by a shoot and compressed air. That is, the base plate 1 can be fitted to the pallet 26 by the use ofa shoot and the like which guides the base plate 1 to the recessed portion 28 of the pallet. The base plate 1 with the terminals 2 staked thereto may be from the pallet 26 together with the base plate 1 by compressed air.

It will be readily understood that the number of the slots 37 should correspond to the number of the terminal fixing holes of the base plate 1 in the case that the terminal guide rods 36 are replaced by the shoot and compressed air, since the slots 37 serve as a guide for the terminals 2 at the time of insertion.

Since the terminal caulking apparatus in accordance with the present invention is constructed as described above, it is possible to simultaneously caulk a plurality of terminals to the base plate in accordance with the invention. Further, the performance of the apparatus is secure and can be easily automatized. Thus, the efficiency of production can be much improved and products of high quality and low price can be obtained in accordance with the present invention.

Furthermore, by the provision of the terminal guide rods, the slippage of the parts due to the vibration given during the conveyance to the subsequent process station can be prevented. Thus, the staking process can be made safe and certain.

t In addition to the above described advantages, there are such advantages as described below.

First, the terminals are all simultaneously staked to the base plate.

Second, the supplying, holding, pressing and removal operations of the parts can be all automated by the use of the jigs of the present invention as described above.

Third, the staking operation can be conducted without error.

Fourth, various sizes of the parts to be staked can be adapted to the staking operation.

Fifth, the base plate can be inserted into and held by the jig with precision.

Now the jig intermittent feeding device employed in the apparatus in accordance with the present invention will be described in detail with reference to FIGS. 12-14.

Referring to FIG. 12, the reference numeral 40 shows a frame on which is provided a rectangular jig sliding board 7 having three side edge portions protruding upward. At the central portion of the jig sliding board 7, a rectangular guide member 41 which projects upward for guiding the

jigs

8, 9, 10, 11, 12 and 13 there along is provided. Another guide member 42 having a rectangular shape is provided on the jig sliding board 7 at the side edge portion thereof which does not project upward to form a jig passage 43 between the

guide members

41 and 42. The

guide members

41 and 42 regulate the position of the jigs by the side walls of the guide members. By the end walls of the guide member 41 and the projected edge portions of the jig sliding board 7, two

jig passages

44 and 45 are formed. Between the back side wall of the guide member 41 and the projected edge portion of the jig sliding board 7 is formed a space for a quick feeding conveyer 23 constituting a feeding mechanism. At the portion where the passage 43 intersects the passage 45, a longitudinal feeding rod 19 is provided so as to push the jig between the side walls of the

guide members

41 and 42. The longitudinal feeding rod 19 is supported by holders 46 secured to the frame 40 and made to move in a horizontal plane by means of a lever 48 and a cam 47 as shown in FIG. 14. At the portion where the passage 43 intersects the passage 44, a lateral feeding rod 20 is provided so as to push the jigs along the end wall of the guide member 41. Further, at the portion where the passage 45 meets the quick feeding coneyer 23, a returning rod 24 is provided so as to push the jigs along the other end wall of the guide member 41. These feeding rods and 24 are supported by holders 46 and made to move in the horizontal plane by means of

cams

49 and 50 and levers 51 and 52 associated therewith similarly to the above described longitudinal feeding rod 19.

Further, the guide member 42 is provided with four positioning devices 18 which project into the passage 43 and are made to move in the horizontal plane by means of a cam and lever mechanism (not shown) similar to the cam and lever mechanism used for longitudinal feeding rod 19 so that they may control the position of the jig as described hereinafter. On the jig sliding board 7, six

jigs

8, 9, 10, 11, 12 and 13 are placed along the

passages

43, 44 and 45 and on the conveyer 23. Each of the

jigs

8, 9, 10, 11, 12 and 13 is provided with a positioning notch 53 on the side wall thereof to be engaged with the top end of the above position regulators 18.

The operation of the jig intermittent feeding device will now be described in detail.

Referring to FIG. 12, six

jigs

8, 9, 10, 11, 12 and 13 are located at the positions (a), (b), (c), (d), (e) and (g) respectively on the

passages

45 and 43 and on the conveyer 23. This is the position before the start of the staking operation. In this position, the top end of each of the positioning devices 18 is engaged with the notch 53 of the

respective jigs

9, 10, 11 and 12 located in the passage 43. Also, in this initial position, the feeding

rods

19, 20 and 24 are all in the retracted position as shown in FIG. 12. The quick feeding conveyer 23 is also initially stopped. Then, when the positioning de vices 18 are disengaged from the notch 53 of the jigs, the longitudinal feeding rod 19 is moved longitudinally to push the jigs in the direction of arrow A between the side walls of the

guide member

41 and 42 by the rotation of the cam 47. Thus, the

jigs

8, 9, 10, 11 and 12 are moved to the positions (b), (c), (d), (e) and (f) respectively as shown in FIG. 13. At the same time that the longitudinal feeding rod 19 is moved conveyer 23 is set in motion in the direction of the arrow C. The jig located on the conveyer 23 at the position (g) is moved to the position (h) while the longitudinal feeding rod 19 moves forward and then retracts into its initial position. Subsequent to this operation, the lateral feeding rod 20 and the returning rod 24 push the jigs located at the positions (f) and (h) in the directions of arrows B and D respectively, and move the jigs to the positions (g) and (a). Thereafter, the feeding

rods

20 and 24 are moved back to the initial position, while the positioning devices are brought into engagement with the notch 53 of the jigs. Thus, the jigs are moved to the subsequent work stations and. That is, the above series of operations constitute one cycle of the staking operation.

By repeating the above cycle as shown in the graphical representation of the timing of the jig feeding operation of FIG. 15, the jigs 8 to 13 are circulated in the passages.

As is apparent from the above description, since the jig intermittent feeding device moves the jigs by means of a cam and lever mechanism and feeds the jigs in circulation by means of a mechanism including a quick returning means utilizing a belt conveyer or a chain, the feeding speed is always stable. Further, the position of the jigs are regulated with high accuracy. Still further, the cycle period of the Operation is short since the quick return mechanism is employed. Thus, the apparatus in accordance with the present invention has a high performance and efficiency in in connection with its practical use in the field of this industry.

Furthermore, the jig intermittent feeding device employed in accordance with the present invention is advantageous for the following reasons:

First, the jigs are fed at a stable speed.

Second, the position of the jigs is regulated with high accuracy.

Third, the period of circulation of the jig feed is short due to the provision of a quick return mechanism.

Fourth, the number of the jigs can be reduced.

The parts supplying device employed in accordance with the present invention will be described now in detail referring to FIGS. 16-19.

Referring to FIG. 16, plate shaped parts (base plates 1 in this case) are successively fed from the part feeder X (shown in FIG. 5A) through a shoot 54 and put into the cut away portions 56 on the periphery of an intermittently rotatable disc 55 provided adjacent to the outlet of the shoot 54. The cut away portions 56 are brought into the position to receive the parts in the horizontal position as shown in FIG. 18. The cut-away portions 56 are closed with a wall plate 57 on the opposite side to that from which the parts are fed into portion 56. Since the thickness of the rotatable disc 55 is not larger than the length of one of the parts, only one base plate is put into the cut away portion and the rest of the base plates are stored on the shoot 54 until the next cut away portion is brought into alignment with the outlet of the shoot.

When one base plate 1 is supplied into the cut away portion of the rotatable disc 55, the rod 60 connected to the disc 55 is moved by the rotation of the cam 58 through a lever 59. The rotatable disc 55 is rotated by a definite angle (45 in this embodiment) by means of a ratchet 62 and a claw 61 at the end of the rod 60. Since the ratchet 62 is integrally fixed to the rotatable disc 55, the disc 55 is rotated about a shaft 63 by a definite angle. On the periphery of the rotatable disc 55 are provided the cut away portions 56 at equal intervals corresponding to the angle by which the disc is rotated in one cycle of operation of the parts feeder, that is, when one base plate is fed thereinto. In this embodiment, accordingly, two rotational steps of the disc bring the base plate from the horizontal position into the vertical position.

On the side of the rotatable disc 55 opposite to that from which the base plates are fed into cut-away portions 56, a block is provided at a position 64 such that the receiving port of the block 65 is in alignment with the cut-away portion 56 when the cut-away portion is vertically positioned to hold the base plate in a vertical position. Thus, the base plate 1 held in the cutaway portion 56 at the position 64 is pushed out of the rotatable disc 55 by means of a push rod 66 and put into the central portion of the block 65 through the groove 67 of the block 65. As shown in FIG. 19, the base plate 1 is pushed out of the block 65 and inserted into the jig by a base plate insertion rod 69. In this operation, a spring 68 prevents the base plate from falling down until it is inserted into the jig.

Subsequent to the positioning of the jigs in front of the block 65, the base plate insertion rod 69 is moved
