Description

Tilt angle inspection device for electron gun convergence cup and bulb spacer assembly of cathode ray tube

The present invention relates to an inclination angle inspection apparatus for an electron gun convergence cup and a bulb spacer assembly of a cathode ray tube.

Generally, a convergence cup and bulb spacer assembly 1 as shown in FIG. 1 is attached to the front end of the electron gun of the cathode ray tube, and three electron beams in a straight line in the case of an inline electron gun at the bottom of the convergence cup 2. A through hole 4 is formed, and a plurality of bulb spacers 3 are usually attached to the side wall portion thereof, and the bulb spacers 3 come into contact with the inner surface of the neck portion of the bulb, so that the front of the electron gun is connected to the neck portion. It will be kept in the center of the circular section.

Therefore, before assembling the electron gun, the bulb cup 3 is assembled to the convergence cup 2 by welding at predetermined positions, and the cup 2 is welded and assembled to the other electrode of the convergence cup 2. And parts are assembled together to form an electron gun.

The convergence cup and bulb spacer assembly 1 of this structure is usually assembled by laser welding the bulb spacer 3 supplied from the other side at the welding station while transferring the convergence cup 2 along the welding assembly and inspection line. Later, it is transferred to an inspection station, which is usually inspected by measuring the relative height of the bulb spacer 3 of the assembly 1 and, as a result, unloading or ejecting according to the quantity and fire.

However, in the welding assembly and inspection line, after welding the bulb spacer 3 to the conventional convergence cup (2), by simply measuring the height by a high gauge by hand, it was determined to be good or bad, which is inconvenient, There was a problem that the test time was not only taken separately but also easily measured incorrectly. In addition, even if the height is accurate, there is a problem that the front end of the electron gun can not be precisely placed in the center when the inclination angle is distorted.

Accordingly, the present invention is to solve the above problems, the cathode ray beam which can automatically process the amount according to the fire, by automatically inspecting the inclination angle of the welded assembly state of the bulb spacer to the convergence cup with a simple structure precisely An object of the present invention is to provide an inclination angle inspection device for an electron gun convergence cup of a tube and a bulb spacer assembly.

A plurality of insertion grooves are formed to insert the bulb spacers of the convergence cup for bulb guns and the bulb spacer assembly, and the insertion block may be installed to adjust the height as necessary.

Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention, as follows.

First, in the overall schematic plan view of the welding assembly and inspection apparatus of the electron gun convergence cup and bulb spacer of the cathode ray tube according to the present invention as shown in FIG. 3, the convergence cup 2 is a refill device 11, a bowl feeder 12, Loading into the initial station ST1 of the welding assembly and inspection line 15 while the initial positioner 540 (shown in FIGS. 4 and 6) is up via the linear feeder 13 and the location and loading device 14. The convergence cup 2 is transferred one by one while the positioner 540 is down along the respective stations ST1 to ST9 of the welding assembly and inspection line 15 to process the corresponding stations ST1 to ST9. Will be performed.

The bulb spacer 3 is supplied to the welding station ST5 via the bowl feeder 16, the linear feeder 17, the rotary device 18, the pickup and the transfer device 19, and converged by the pusher device 30. The laser welding is performed by the welding device 20 in a state of being supported at a predetermined position of the cup 2, and this process is repeated as many times as necessary for the bulb spacer 3, and then the eject chute 21 is subjected to various inspection processes. Through quantity, fire is separated and ejected.

Figure 2 shows a process performed in the welding assembly and inspection apparatus of the electron gun convergence cup and bulb spacer of the cathode ray tube according to the present invention described above. In Fig. 2, the convergence cup (2: denoted by C / C in Figs. 2 and 19) and the bulb spacer (3: denoted by B / S in Figs. 2 'and 19) are processed and prepared, respectively. The feed is put into the bowl feeders 12 and 16 in step S21, and linear feeding is carried out in steps S2 and S22 by the linear feeders 13 and 17 connected to the bowl feeders 12 and 16. As such, the bowl feeders 12 and 16 and the linear feeders 13 and 17 may include the convergence cup 2 accommodated by the bowl 200 and 601 and the vibration means 201 and 602 in FIGS. 9, 10, 12, and 13. When the bulb spacers 3 are discharged one by one, the linear spacers 13 and 17, which are similarly constituted by the vibration means 301 and 702 and the linear feeder plates 300 and 701, are continuously flowed in a row. In the case of the convergence cup 2, since the size is large and the quantity that can be stored in the bowl 200 is limited compared to the bulb spacer 3, a separate refill device 11 may be provided in FIGS. 8 and 10. The refilling apparatus 11 includes a hopper 100 capable of storing a large amount of convergence cup 2, a flow guide 102 of the convergence cup 2 communicated with the lower end of the hopper 100, It comprises a vibrating means 101, the vibrating means 101 by the detection signal when there is no convergence cup (2) on the bottom of the bowl 200 by the Tachiba 204 and the touch sensor 203. This operation causes the convergence cup 2 to flow through the flow guide 102. In order to prevent the convergence cup 2 from flowing excessively from the hopper 100 into the flow guide 101, an overflow preventing plate 103 is installed on the top of the flow guide 101 as shown in FIG. 8. Can be.

In the case of the convergence cup 2 through the linear feeding step (step S2 and step S22) in FIG. 2, the convergence cup 2 is the positioner 540 of the welding assembly and inspection line 15 in the positioning step (step S3). First, the position of the convergence cup 2 is set so that the position can be set through the electron beam passing hole 4. Also, in step S4, the welding assembly and inspection line 15 is loaded into the initial positioner 540.

That is, the convergence cup 2 continuously fed from the linear feeder 13 in a row as shown in FIG. 11, which is the right side view of FIGS. 9 and 9, has a plunger reciprocating by the air cylinder 401 at its exit. By advancing 402, the driving roller 404 and the driven roller 405 are engaged with each other to rotate together when the driving roller 404 rotates. At this time, the other convergence cup 2 is in the standby state at the outlet of the linear feeder 13, and when the plunger 402 is backward, the outlet is opened so that one convergence cup 2 can be discharged, The above operation is repeated.

During the rotation, when the position of the electron beam through hole 4 is confirmed by the optical sensor 406, the driving roller 404 immediately stops by the confirmation signal, and the suction bar 410 is waiting on the upper portion. Is inserted into the convergence cup 2 in advance of the air cylinder 408 and brought into a vacuum state through the vacuum hose 411, the convergence cup 2 is attached to the adsorption bar 410, and then the air cylinder As the 408 retracts and the air cylinder 407 retracts, the convergence cup 2 is positioned above the positioner 540 of the first station ST1 of the weld assembly and inspection line 15. At this time, when the air cylinder 408 is advanced and the vacuum state of the vacuum hose 411 is released at the same time, the convergence cup 2 has the positioning pin which is moved to the upper end of the positioner 540 with the electron beam of the convergence cup 2. It is loaded while being inserted into the through hole (4). The connecting fixture 408 is a fixing device for fixing the air cylinder 408 to the connecting rod of the air cylinder 407.

In this manner, the convergence cup 2 having the loading operation is transferred one step through the welding assembly and inspection line 15 to perform a predetermined process at each station ST1 to ST9 and be discharged.

In the welding assembly and inspection apparatus according to the present invention in the welding assembly and inspection line 15, a positioner 540 is disposed at each of the stations ST1 to ST9, and the plurality of positioners 540 are moved up during the process execution time. Then, it is held in the rising position, and then in the down state, the down state (step S5) is maintained for the transfer time to transfer to the next stations ST1 to ST9. For example, in FIG. 2, after the convergence cup 2 is loaded, the positioner 540 is lowered (step S5), and is moved to the welding station ST5 in step S6. However, in FIG. 3 and below, three steps are interposed between the welding station ST5 and the loading station ST1, indicating that other processes may be performed. For example, inspection of the convergence cup 2 itself, or the process of air | atmosphere is mentioned.

In FIG. 4, the transfer bar 551 shown in FIG. 6 is shown in dashed-dotted line and in FIG. 5 in a removed state. In FIG. 4 and FIG. 5, a positioner 540 is disposed at each of the stations ST1 to ST8, and the positioner 540 is disposed up and down via an up-down connecting rod 511 by up-down cams 532 to 535 installed at a lower portion thereof. Up and down along a predetermined cam diagram. The final station ST9 is provided with a knockout-bar 540 'which is fixed to the positioner 540 of the previous station ST8 and moves up and down together, and is transferred to the station ST9 when it is up after transfer. The assembled and inspected convergence cup and bulb spacer assembly 1 is discharged from the transfer means into the eject suit.

Cam diagrams of the up-down cams 532-535 are shown in FIG. 19 as an example. In FIG. 19, the up-down cam diagram C / C UP / DOWN of the convergence cup 2 is down during the transfer T of the convergence cup 2 in the transfer diagram C / C TRANSFER of the convergence cup 2. Must be up (eg between θ9 and 360 degrees) and up at the time of untransfer (UT) for return (between θ1 and θ5). In addition to these conditions, the up state must be maintained for a time required to perform a predetermined process at each station ST1 to ST9 (between θ1 and θ8).

This up state is required, for example, during the transfer and pushing and welding times of the plurality of bulb spacers 3 in the welding station ST5. That is, in the welding station ST5, the positioner 540 is connected to the up-down connecting rod 511 via the step motor 550, as shown in FIG. 3, and C / C ROTATING and R / S TRANSER in FIG. As shown in the PUSHING, WELDING diagram, the positioner 540 is configured to be intermittently rotated at a predetermined rotational angle and weld the bulb spacer 3 at each rotational angle, respectively. After welding, it goes down. The stations ST6 to ST7 may be appropriately selected between θ1 and θ8 during the time required for the inspection process, and thus, the cam diagrams to be converted may be selected according to the characteristics of each process. In FIG. 4, fixing plates 512 are provided to fix two or more up-down connecting rods so that the stations ST2 to ST4 follow the cam diagram of one up-down cam 533, and similarly in stations ST6 to ST8. Fixing plates 512 and 513 are installed.

On the other hand, each connecting rod 511 is configured to reduce the resistance through the rolling motion by contacting the cam surface of the up-down cams 532 to 535 via the driven roller 531 at the lower end, the up-down cams 532 to 535 The handle 22 is fixed to the shaft 530 of the up-down cams 532-535 to adjust the point of action of the. Accordingly, the point of action of the cam can be easily adjusted when it differs from other movements, and when the point of action of any one of the cams differs, the up-down cams 532 to 535 each have a bolt 532 on the shaft 530. And 535 to be assembleably fixed, the mutual relationship can be adjusted.

In addition, as shown in FIG. 3, the down stroke may be configured to ensure the down stroke by tension springs 522 and 524 in addition to its own weight during the down stroke, and the compression springs 521 and 523 to prevent excessive rise due to inertia during up stroke. It may be installed between the guide blocks 502 and 503 fixed to the fixing plate 501 and the connecting rod 511.

5 and 6 show the transfer means. The transfer means has a pair of transfer bars 551 fixed by the reciprocating block 553 at predetermined intervals that the positioner 540 can up and down, guided by the guide block 554, The convergence cup 2 is transferred by reciprocating by the interval. In the transfer bar 551, the convergence cup seating grooves 552 are formed inward to each other so that the convergence cup 2 is held at a predetermined position when the positioner 540 is down by the up-down cams 532 to 535. It is inserted into the seating groove 552. As such, the convergence cup 2 is transferred from the seated groove 552 to the seated groove 552 and then up at a predetermined position by the positioner 540 to perform a predetermined process.

7 shows an example of a reciprocating mechanism of the transfer bar 551 and the reciprocating block 553 using a cam and a spring. A tension spring 555 is installed at one end of the reciprocating block 553 to move to the right in the drawing, and the other end is connected to one end of the driven lever 558 via a chain 556 and a guide sprocket 557. The other end of the driven lever 558 is fixed to the frame by the shaft 559, and the transfer cam 560, which rotates together with the shaft 561 in the middle, contacts the driven lever 558 at the bottom thereof, By rotating 558 in accordance with the cam diagram, the reciprocating block 553 moves to the left against the elastic force of the tension spring 555 via the chain 556. In the case where the transfer means has such a structure and the same axis as the axis 530 of the up-down cam or the same rotation as the axis 530, the cam curve of FIG. 19 is illustrated by the C / C TRANSFER of FIG. 19. In addition to this structure, a conventional air cylinder may be used as the transfer means.

In FIG. 2, the bulb spacer 3 is fed in a continuous alignment state from the linear feeder 17 in step S22, and then the bulb spacer rotator of the rotating device 18 at the end of the linear feeder plate 701 in FIGS. 12 and 13. The solenoid 703 and the stopper 704 operate to flow to 801 and not to flow one or more of the bulb spacers from the ends of the linear feeder plate 701 as shown in FIGS. 13 and 15. Stop the flow of 3). Thereafter, when the rotary cylinder 802 rotates in step S23, the rotator 801 rotates together to rotate the bulb spacer 3 by 90 degrees in an upright state, and at this time, the pick-up finger 810 of the air chuck 811 By operation, the bulb spacer 3 in an upright state is gripped as shown in Figs. 12 to 14 (step S24).

After being held by the pick-up finger 810 in this manner, the rotator 801 returns to its original state, and as shown in FIG. 12, the air chuck 811 is positioned at the position 811 ′, that is, the welding assembly and inspection line 15. Is transferred to the welding station ST5 by the reciprocating means (not shown) (step S25). By moving in this way, the upright bulb spacer 3 gripped by the pick-up finger 810 is a predetermined angle of the conversion stub 2 located on the positioner 540 in the up state of the welding station ST5 in FIG. It is adjacent to the side wall surface of the position. In this state, as shown in FIG. 16, the bulb spacer 3 is joined to the convergence cup 2 side by the pusher device 30, and the air spacer 811 is released, thereby allowing the bulb spacer 3 to pick up the finger 810. In contact with the convergence cup (2), in which the pick-up finger (810) returns to its original position with the air chuck (811) and is in standby to pick up the next bulb spacer (3). (Step S7 '). The fixing step (step S7 ') may further include a means for reciprocating in a direction perpendicular to the reciprocating movement in addition to the reciprocating movement in order to ensure the separation of the pick-up finger 810 and return to the original position. have. The reciprocating means not shown may be a conventional reciprocating means such as an air cylinder or the like, and may also be constituted by the transfer cam 559 and the spring 555 shown in FIGS. 6 and 7.

As described above in the fixed state in which the bulb spacer 3 is pushed to the convergence cup 2, the welding device 20 maintains the up position of the positioner 540 in the welding station ST5 as described above. By firing, the bulb spacer 3 is welded to the convergence cup 2 (step S8 in FIG. 2), and upon completion of welding, the bulb spacer 3 is released (step S8 '), and the step motor 550 After rotation by a predetermined angular displacement (step S9), it is determined by counting whether the previous bulb spacer 3 has been welded in step S10. If the previous bulb spacer 3 has not been welded, the process returns to step S7 'again. To step S10 are repeated. Thus, steps S21 to S25 for supplying the bulb spacer 3 are carried out by placing the desired number of bulb spacers while transferring the convergence cup 2 onto the positioner 540 and up the positioner 540. And (3). That is, as shown in the B / S TRANSFER, PUSHING, WELDING diagram and C / C ROTATING diagram in FIG. 19, the transfer of the bulb spacer 3 during the up time (θ1 to θ8) of the C / C UP / DOWN diagram is shown. , Pushing and fixing the welding and rotation of the convergence cup 2 to a predetermined angular position are repeated N times when the N bulb spacers 3 are attached to one convergence cup 2. When the transfer of the bulb spacer 3 together with the chuck 811 is completed, pushing is performed by the pusher device 30 and the return of the air chuck 811, that is, the untransferring UT is performed. At the time when the pushing is completed, the welding W1 to WN is performed. Therefore, in consideration of such a timing chart, the controller performs control by the controller or transfers the bulb spacer 3 to the welding station by the transfer cam 559 and the spring 555 shown in FIGS. 6 and 7. In such a configuration, the cam surface curve and the cam curve of the transfer cam should be selected in consideration of the B / S TRANSFER diagram of FIG. 19 as an example. In the C / C ROTATING diagram of FIG. 19, the rotation of the bulb spacer 3 can be directly performed at the transfer position of the convergence cup 2. 2) It is not necessary to rotate R1, and the convergence when the bulb spacer 3 is welded at each position where the convergence cup 2 and the positioner 540 have not returned to their original state at the final rotation RN. It will be necessary to return the convergence cup 2 and the positioner 540 to their original state before the down start time θ8 of the cup 2.

After the welding of the previous bulb spacer 3 is completed in step S10 in FIG. 2, the positioner 540 is lowered in step S11, and the convergence cup 2 is positioned in the seating groove 552 of the transfer bar 551. (2) is transferred to the inspection stations ST6 and ST7 by the rotation of the transfer cam 560 and the action of the tension spring 555 (step S12). In the inspection stations ST6 and ST7, the welding assembly state of the bulb spacer 3 to the convergence cup 2 is measured by the height inspection apparatus 40 and the inclination angle inspection apparatus 50 as shown in Figs. It is checked (step S13). In FIG. 17, when the positioner 540 is up by the rotation of the up-down cam 535 as described above from the transfer bar 551, the contact block 41 is positioned at a position corresponding to the height of each bulb spacer 3. By the contact with the contact block 41, the clearance sensor 42 determines the amount and the fire of the height of the bulb spacer 3. When the defect is defective, the ejection chute 21 receives the defect signal from the sensor without processing the inclination angle by the inclination angle inspection device 50, which is the next step, and processes the defect chute 21 in the eject chute 21 by the storage means and the control means (not shown).

In FIG. 18, the inclination angle inspection device 50 includes an insertion block 51 and a defect detection sensor 52, and the insertion block 51 has an insertion groove 51 ′ at a position where the bulb spacer 3 can be inserted. Is formed, when the bulb spacer 3 is not inserted into the insertion groove 51 'when the positioner 540 is up, the failure detection sensor 52 generates a failure signal. In this case, as in the height inspection process, the bad signal is received by the storage means and the control means, which are not shown, and treated in the eject chute 21 as bad. On the other hand, the insertion block 51 may be configured to form a plurality of insertion grooves 51 ′ to insert the bulb spacer 3 of the convergence cup and bulb spacer assembly of the multi-tube electron gun, depending on the tubular type The insertion block 51 may be installed to adjust the height. In addition, after the positioner 540 is up, the height inspection device 40 and the inclination angle inspection device 50 are also lowered and inspected as shown by the arrows in FIGS.

When the inspection process is completed in this way, the convergence cup 2 is transferred again and unloaded in step S14. In FIG. 4 and FIG. 5, the first standby at the station ST8 is transferred to the station ST9 and then discharged to the eject chute 21 by the eject bar 540 ′.
