The striking times can be arranged in advance. When a counter counts to the set value, the counter automatically stops counting. The utility model has the advantages of convenient operation, simple structure, accurate counting, and good interference prevention performance. The utility model is especially suitable for striking test places of machine core plates or display tubes of televisions.

Description

The machinery ignition device

The utility model relates to a kind of mechanical ignition device of the sparking test usefulness of the movement circuit plate of a kind of ignition device, particularly television set or picture tube.

The ignition device that uses generally adopts the pin type sparking at present, and this igniting needle places the inside of sparking casing, causes the sparking distance to be difficult to regulate; When the sparking number of times reached the test determination value, motor can not stop automatically in addition, needed artificially action, made test number (TN) be difficult for accurately control.

The purpose of this utility model be to provide a kind of adjusting sparking distance be very easy to, can self-braking mechanical ignition device when the sparking number of times reaches preset value.

The utility model adopts the spheroid discharge mode, comprises a moving ball discharge structure, a static discharge spherical structure, a casing, a case lid and a contact shoe.Moving ball discharge rotates under the drive of motor, and it is static that the static discharge ball keeps, and the arcing distance between two spheroids is adjusted by moving of static discharge spherical structure, and the regulating handle of static discharge spherical structure is outside case lid; Electric charge on the moving ball discharge is to come by the contact conduction of contact shoe one end, and a high-voltage line is connected on the other end of contact shoe, and another root high-voltage line is connected on the static discharge ball; The employing count control circuit comprises a sensitive switch, a counter, the moving circle of moving ball discharge revolution, and sensitive switch is touched once, and counter is just counted once, and when reaching the preset value of regulation, counter provides signal, and the motor outage stops operating.

The utility model has been simplified drive mechanism by changing discharge mode; Owing to adopt the sensitive switch of Mechanical Contact formula to transmit count information, omitted the shielding construction that uses in traditional discharge mode; Owing to outside the discharge case lid, make the design of the regulating handle of arcing distance the adjusting of arcing distance very convenient; By the change of counting mode, can count automatically, also can stop automatically, the accuracy of counting has been improved; Case lid can rotate in addition, can mention, and makes maintenance very convenient.

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is a structure vertical view of the present utility model.

Fig. 3 is electrical control figure of the present utility model.

The utility model will be further described below in conjunction with accompanying drawing.

Structure of the present utility model mainly is made up of a moving ball discharge structure, a static discharge spherical structure, a casing, a case lid and a contact shoe.

Moving ball discharge structure mainly comprises moving ball discharge 2, motor 4, rotating disk 22; Motor 4 can be equipped with decelerator according to test requirements document, and motor 4 drives rotating disk 22 and rotates, and an end of pillar 21 is installed on the rotating disk 22, and moving ball discharge 2 is housed on the other end; The upper surface of rotating disk 22 is electric conductors.The static discharge spherical structure mainly is made up of static discharge ball 3, pole 31, bearing 32, handle 35 and guide rail 34, is connected with a high-voltage line 61 on the static discharge ball 3; Pole 31 adopts the insulating material discharge effect better, one end of pole 31 is connected with static discharge ball 3, the other end is installed on the bearing 32, pole 31 is in the connecting hole of bearing 32, the two both can be fixedly connected, also can allow pole 31 in bearing 32, slide, mix up originally behind the arcing distance again with marking closely screw; Bearing 32 is enclosed within on the adjusting screw(rod) 33 of handle 35, and can slide on guide rail 34, so just can adjust arcing distance between it and the moving ball discharge 2 by regulating static discharge ball 3.Casing 5 is made by insulating sheet material, and motor 4 is contained in its inside, and a hole is arranged on the top panel of casing 5, the supporting bracket that is used to install rotating disk 22, and rotating disk 22 connects together through this hole and motor 4.Case lid is made up of protective cover 1, backing pin 15 and handgrip 11, and protective cover 1 is fixedlyed connected with backing pin 15, and protective cover 1 usefulness transparent insulation material (as colourless poly (methyl methacrylate) plate) is made, and can see the course of work in the sparking process like this.Protective cover 1 is connected in the back of the working face of mechanical ignition device with two hinges of casing 5 usefulness (not drawing among the figure) at least; One annular hole slot is arranged on the support arm 7, the center of this annular hole slot is on the hinge of hinge, backing pin 15 is inserted in the annular hole slot, when mentioning handgrip 11, protective cover 1 rotates around hinge, backing pin 15 moves in the annular hole slot of support arm 7, and the design of annular hole slot should guarantee that protective cover 1 has the space being convenient to keep in repair and can stop when up mentioning, and protective cover 1 can be close on the upper surface of casing 5 when falling.Contact shoe is made up of contact carrier 8, conductive reed 81; Contact one end of conductive reed 81 is pressed on the rotating disk 22, and the other end is connected with a high-voltage line 62 and is fixed on the contact carrier 8.Sensitive switch 6 is installed in pillar 21 next doors, when rotating disk 22 rotates, can touch on the contact of sensitive switch 6, makes it to send count information to counter 10, whenever touches once, and counter 10 countings once.In Fig. 3, press the button 9, motor 4 begins to rotate, and drives moving ball discharge 2 and rotates, and pillar 21 touches sensitive switch 6 (as the SS-3L255 of OMRON company), counter 10 (as the H7CL-A of OMRON company) begins counting, when counting reached set point number, counter 10 provided signal, and normally-closed contact 10C disconnects, motor 4 stops operating, and counting finishes.Press normally-closed contact 16 midway at counting and can make the counting Halfway Stopping.
