Best 3 sisters to make n h Referring to Figures 1-6, Figure 1 shows a carousel 1, with jis g-3a and 3b. A gripper mechanism 2 including a provided gripper is provided along the conveyor 1. Con The conveyor 1 is intermittently motor-driven (in the N direction) by well-known components not shown. Then, the gripper mechanism 2 is stopped at a position facing the work station for a certain period of time.

The functionality of the gripper mechanism 2 is controlled by electrical and/or is to clamp the lead wire 10 of an electronic component, and the lead wire 10 is a part of it. At 10a it projects beyond the jaws 3a, 3b of the gripper mechanism 2. this The clamping process is performed on the parts at the work station S according to a predetermined spatial positioning. Orient 10a.

At the work station S, the jaws of the gripper mechanism 2 located at this station Immediately adjacent to the position Q1 taken by the ends of 3a, 3b, two or upper cutting assemblies 4 and the heads of the lower cutting assembly 5 respectively operate.

The upper assembly 4 consists of a first tool 6 and a second tool 7. First tool 6 (striped end) The head is comb-shaped and has teeth 6a and grooves 6b (FIG. 5). The head of the second tool 7 is also the same. Although it has a comb shape, (its teeth 7a and grooves 7b) are offset from the comb of the first tool. (Fig. 5), that is, the teeth of one comb fit into the grooves of the other comb, and vice versa. The grooves on one comb fit into the teeth on the other comb.

In particular, the teeth 7a of the second tool 7 extend beyond the grooves 6b of the first tool 6 (see Figure 4). (see). The advantages of this detailed structure will be seen from the following explanation.

The lower assembly 5 consists of a third tool 8 and a fourth tool 9. The head of the third tool 8 is It faces the head of the first tool 6 and is also comb-shaped, with its teeth and grooves facing the head of the first tool 6 in a horizontal plane. It is constructed symmetrically with respect to the teeth 6a and the grooves 6b.

The head of the fourth tool 9 facing the head of the second tool 7 is also comb-shaped, and both tools 6. As described above for 7, it engages with the comb of the third tool 8.

As can be seen from FIG. 4, the teeth of the first tool 6 and the third tool 8 are at a position W When it makes contact on the QI side, it tilts to form a seat or notch 12 with a triangular cross section. Similarly, on the opposite side of this seat 12, the third tool 7 and the 49th tooth have a triangular cross section. The seat constitutes a notch I3.

Tools 7.9 (second tool and fourth tool) slide on the corresponding surfaces, that is, on the guide 15. These guides 15 are supported by moving associated sliders 21 (FIG. 2). form two flat parallel surfaces configured on either side of the head of the carriage 30.

The same number of metal tubes 16 are provided on the slider 21, and the axes of these metal tubes are related to each other. perpendicular to the transverse direction of the guide.

A bearing 17 is keyed to the outer surface of the metal tube 6, and is keyed to the shaft 20. It slides within the cam track 18 formed on the disk 19.

The other tools 6.8 (first tool and third tool) are supported by the corresponding sliders 14. Then, these sliders 14 move in the direction of slider 21 [tWJJ], and from FIG. As shown, one side of the surface 22 (forming a flat parallel surface) and the slider 2 1 on the other side. The same number of bins 23 as the metal tubes 16 are on the slider 1. 4 and are similarly inserted into the metal tubes 16, respectively, and the bearings 24 are attached to the bins 23. A cam track that is keyed and formed on the disc 19 in line with the cam track 18 25.

The contour of the cam track 18.25 moves the corresponding tools 7.9 and 6.8 in both directions TI, T It is formed to move to 2. That is, both assemblies 4.5 are These cam tracks guide the assembly 4.5 in directions T1 and T2 respectively until they make contact at the pads. (first step; see Figure 4). At this point, cam+jL road 25 is While both tools 6.8 are stopped, the cam tracks 18 are moved to their respective heads as described above. Move the remaining tools 7.9 slightly laterally in the direction of T1 until they touch ( 2nd stage). (The previous tool 6.8 is locked) T1 of both sides 7.9 A lateral movement in the direction is possible due to the play between the metal tube 16 and the bottle 23. S The shaft 20 is radially supported on a carriage 30 via a well-known mechanism 26a. The arm 27 is rotated by the control shaft 26 and keyed to the end of the control shaft. At the same time, this arm 27 is connected to the tie rod 29 via the joint 28. The tie rod 29 is further connected to one end of the lever arm 32 via a joint 31. The other end of the lever arm 32 is supported by a fixed structure 33.

The lever arm 32 has a cam track formed on the circular surface of a drum (not shown) at its center. The bottle of the small diameter roller 34 sliding on the road 35 (partially shown by the broken line in Fig. 1) is The drum is supported by a main shaft 36 (first shaft) supported radially on a fixed structure 33. (Fig. 1), and is rotated at a constant speed (in the M direction) through a well-known mechanism (not shown). be done.

The rotation of the drum causes the arm 32 to vibrate in a plane perpendicular to the plane of FIG. Ru. Along with this, the control shaft 2G periodically vibrates, and therefore the cam 19 is It vibrates periodically in the K+ direction (Figure 2).

A carriage 30 containing a control shaft 26 is connected to a rail connected to a fixed structure 33. It is supported by wheels 37 that slide on 38.

This sliding causes the carriage 30 to move laterally in the direction of F, , F, and to move the control shaft 26 laterally in the F+ and Fz directions.

Said lateral movement is achieved by a lever 39 supported at 40 on the fixed structure 33. It will be done. The arm 39a of this lever is a disc 9 keyed to the main shaft 36. A small diameter rotor slides within a track 42 (partially shown as a broken line) formed on one side of 6. while supporting the roller 41, the remaining arm 39b includes a slot 43, which A small diameter roller 44 supported in the radial direction by a carriage 30 is connected within the cut 43. ing.

When the disk 96 is rotated in the M direction, the lever 39 vibrates around the support 40. Ru. This causes the carriage 3o to move to two positions, namely the operating position R (Fig. 1) and It moves between non-operating positions 1r.

For the inactive position i1, only the position taken by the arm 27 and the associated joint 28 (first (in the figure) is indicated by a dotted line.

A spring 9o is interposed between the fixed structure 33 and the carriage 30, and its function is that of a roller. 44 with respect to the associated slot 43; roller 41 with respect to the associated track 42; (This keeps the roller in constant contact with the raceway.) Furthermore, the shaft 2o vibrates. It is obvious that the purpose is to "remove" the play in the above-mentioned mechanism that provides rotation. cormorant.

At work station S, there is a grid downstream of the cutting assembly 4.5 (as viewed from position WQI). The upper part 45 is located, and its j = +-46, 47 are supported by the carriage 30 at 51. They are each hinged to a small frame 5o. Also these jaws are the second As can be seen, they are mutually articulated at 88.

The gripper 45 closes due to the action of Jia-46 on the fourth day.

and the opening position is determined.

Inside the jaw 46 is a strut that is integral with the jaw 46 and faces the other jaw 47. There is a squid board 49.

The small frame 50 has a pneumatic jack 52 supported by the carriage 30 at 53. is activated.

The operation of the above device will be explained below.

As mentioned above, the gripping tool of the gripping mechanism 2 is positioned by the circular conveyor and mounted on the station. It is locked open for a predetermined period of time at the version S (more precisely, at the WQI).

The gripper mechanism 2 behind the lead wire lO! ! Part 1 outside of −33, 3b The positioning of 0a into S is prevented because the carriage 30 is in the non-operating position 1r. do not have. When the carriage 30 moves from position fil to R, both assemblies 4.5 are pulled to the maximum. Then move the gripper 45 to the position shown in FIG. ! 46.47 is at degree 1.

At this point, the gripper 45 is closed by the jack 48 (FIG. 4). this is Place the striker plate 49 on the lead wire so that part IQa of the lead wire is bent downward. The portion 10a is made to interact.

After the above, the operation of the jack 52 is released. The small frame 50 has a jacket 5 Moment that tries to rotate in the elastic direction of the return spring (not shown) etc. built into 2. under the action of Therefore, the lead wire 10a gripped by the gripper 45 is in a tensile state. This is preferable for the reasons described below.

In fact, at this point, the gripper machine tl12! ! -3a and 3b are lead wires 10? When partially released, the main body 11a (or the lead wire as in the example of FIG. The curved portion 11b) formed in the jaws 3a and The component 11 moves laterally in the E direction until it collides with the striker surface 55. by this After cutting is completed, a component 11 with a lead wire of a predetermined length is obtained, and the length of this lead wire is is the most suitable length for inserting the lead wire into the relevant hole in the printed circuit board (not shown). be.

Resetting the maximum clamping pressure that the jaws 3a and 3b apply to the lead wire 10 and the phase shift -synchronized, the assemblies 4.5 are directed toward each other in the directions TI and T2, respectively. Move laterally. This mutual approach is achieved by the contact of the associated heads as shown in Figure 4. and stop.

(Stage 1). In the first stage of the process, as detailed in Figures 6a and 6b, the tool 6. The zone 60 is crushed by the scraped edge of 7.8.9.

That is, in the zone 60 on the main body 11a side of the part, a pyramid-shaped ring is formed. A shell 61 is formed, while on the opposite side (tool 7 protruding with respect to 46b of tool 6) A contour 62 consisting of a crushing portion 62a is formed by the toothed portion 7a of the The tongue piece 62b is not separated from the crushing part 62, but is inclined downward and branches (No. 4.6). (Compare figure a).

This first stage, which does not involve waste production, primarily pushes zone 60 as described above. It consists of collapsing to form contours 61, 62. The cutting tool will be in contact with the At the same time as the crushing, it is also possible to partially cut off the contours 61,62.

This uncoupling occurs when tool 6.8 is locked while tool 7.9 is aligned in the direction of Tl. This is done reliably in the second stage of moving in time.

This completes the cutting of the zone 60 according to the contour of FIG. 6c, and this cutting operation also Apparently no waste (except part 10c) is formed.

The above cutting operation is performed by moving the frame 50 in the Z direction until it reaches the end position Z (Fig. 2). Rotate. At this point, the gripper 45 moves to the ``open'' position and grips the jaw of the lead wire. The stress applied from the striker plate 49 to the portion 10c included between -46.47 is facilitates removal of the lead wire portion 10c from the working ends 46a, 47a of the jaws. do. The removed lead wire portion is placed in a collection gas connected to a suitable container (not shown). It falls into the id 70.

Relative retraction of cutting assembly 4.5 and lateral movement of carriage 30 from position R to position I This completes the basic cycle of the ATL.

After completion of the cycle, the carousel 1 has its lead vA10 cut as described above. The part 11 that has been removed is transferred from the work station S to another station (not shown). and at the same time the new lead wire 10 is to be cut in the same manner as above. The shelving part 11 is fed to the work station S by a further gripper 2.

As can be seen from the features of this invention, in this device, the lead wire is connected to the main body as in the above example. Part 11 set in a direction parallel to the axis of 11a and not perpendicular to the axis of the main body can also be cut. You can cut it off.

Modifications for processing the leads of component 11 shown at 100a and 100b in Figure 7a Examples are shown in Figures 7a and 7b.

With respect to the position Q1 taken by the jaw 33.3b at the working station S, the cutting assembly 4. On the opposite side of 5, facing station S, (punch and counter punch, (or a suitable gripper, etc.) is provided, and this machine tR80 connects the lead wire 1. 00b (which protrudes slightly from the jaws 3a and 3b) is locally deformed and (i.e. the part of the lead wire inside the jaws 3a, 3b - see Figure 7a) ) are formed with small teeth 81.

The work station S also includes one group of the above examples downstream of the cutting assembly 4.5. Instead of the ripper 45, (having the same configuration as the gripper 45) A first gripper 45a and a second gripper 45b are provided, one of which is connected to the lead wire 1. 00a, and the other one holds lead cotton 100b (for several days).

Both grippers 45a and 45b are supported by the frame 50 and are synchronously controlled. each gripper is actuated by a corresponding pneumatic jack 48a, 48b. Configure the "open" and "closed" positions of the jaws.

The unit formed by the second gripper 45b and the attached jack 48b is a frame It is possible to move laterally in the E direction with respect to 50. Lead wires 100a and 100b are jaws 3a, 3b, the lead wire 100b is partially released from the second grit. When the jack 82 is activated in response to being gripped by the pawl 45b, the unit is moved in the E direction. The lead wire 100b is set to be moved laterally in the direction and the lead wire 100b is placed under tension; The teeth '81 are shown in Figure 7b! l　A collision with the striker surface 55 of 3a, 3b to hit

After being cut in this way, the lead wires 100a and 100b are connected to the main body 11a of the component 11. It protrudes from the head by a predetermined amount. The following advantages are the same as those manipulated in Retired Emperor. etc.

That is, this device cuts the lead wire according to the pyramidal contour 61 (the first 6a, 6b, 60), this contour does not exceed the cross-sectional area of the lead, and this point is Combined with the fact that the contour is pointed, as above (therefore, with the above contour) Extremely advantageous for inserting cut leads into corresponding holes in printed circuit boards. be. Also, the above contours are obtained without producing any waste other than partial toe.

Moreover, this device can be used in any of the structural configurations considered here after cutting is completed. , giving a lead wire of a predetermined length.

The operating mechanism of this device is either an °on ° or an “off” type, which means that the microprocessor It is important in terms of the interface with the unit.

The device is also of a general-purpose type, i.e. the maximum or Then, the lead wires of the component 11 can be cut regardless of the distance between the lead wires. deer If the head of each tool 6.7.8.9 is appropriately shaped, this device can also Pointed edges with profiles other than ramid shapes are also achievable.
