Description

The chip mounter Star axis AC servo motor calibration power supply

Technical field

The utility model relates to a kind of Siemens chip mounter, relates in particular to the power supply of this Siemens's chip mounter Star axis AC servo motor.

Background technology

Chip mounter is one of equipment of a kind of employing surface installation technique (Surface Mount Technology is called for short SMT).So-called SMT technology, it is with the Surface Mount Component, subsides, is soldered to the circuit multi pack technology on the assigned position of printed circuit board surface, technology of inserting perforation at the circuit board dress different from the past, because the miniaturization of its electronic devices and components, electronic product with the SMT assembling has the comprehensive advantage that volume is little, performance good, function is complete, price is low, is widely used in industries such as Aeronautics and Astronautics, communication, computer, medical electronics, automobile, office automation, household electrical appliance.

Siemens chip mounter Star axle needs a servo power supply when install adjusting, guarantee to install AC servo motor and be in the zero pulse state, otherwise head has shake during work, influence the chip mounter use.

Siemens Company provides special-purpose calibration power supply in the prior art, can overcome the above problems preferably, but there is certain defective in use, the specification requirement that provides according to Siemens Company, stipulate that this power supply is controlled in 5 minutes in use, otherwise have the danger of burning the Star spindle motor.

How preventing maintenance personal's improper use damage equipment, causing heavy economic losses is the problem that the technical staff will solve.

Summary of the invention

The utility model technical issues that need to address have provided a kind of chip mounter Star axis AC servo motor calibration power supply, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

The utility model comprises: connect the transformation module that input 220V exchanges, connect the rectification module of transformation module; Also comprise: the voltage stabilizing that links to each other with rectification module/current limliting module, with the time delay module that voltage stabilizing/the current limliting module links to each other; Time delay module connects 5V output.

Compared with prior art, the beneficial effects of the utility model are: through technological improvement, realize that the safety of calibration power supply is controlled, avoid owing to the damage of misoperation to equipment.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:

As seen from Figure 1: the utility model comprises: connect the transformation module that input 220V exchanges, connect the rectification module of transformation module; Also comprise: the voltage stabilizing that links to each other with rectification module/current limliting module, with the time delay module that voltage stabilizing/the current limliting module links to each other; Time delay module connects 5V output.

As seen from Figure 2: the operation principle of the voltage stabilizing current limliting module of the prior art that adopts in the utility model is: the direct voltage that obtains 12V after the 220V alternating current process T1 transformation D1-D4 rectification C1 filtering; pass through Q1 again; R1; R2; RW1; the voltage stabilizing circuit that IC1 forms is exported 5V voltage on C2; when certain reason C2 voltage rise height that powers on; through RW1; R2 sampling IC1 amplifies reduces the Q1 base voltage; keep the voltage on the C2 to be stabilized in 5V; Q2; Q3; R3 forms current foldback circuit; when forming 0.6V voltage above 2.5 ampere-hours on R3, load current make Q3 conducting collector electrode output current that the Q2 base voltage is raise; Q2 conducting collector voltage descends; the Q1 base voltage descends, and the Q1 ducting capacity weakens holding current in 2.5 amperes.

The time delay module operation principle of the prior art that adopts in the utility model is: circuit when R4, R5, R6, R7, R8, R9, R11, R12, R13, J1, J2, U1, K1, K2, K3, Q4 and starting switch are formed the court of a feudal ruler, when pressing starting switch U1 get electric, 3 pin of U1 output high level; One the tunnel maintains J2 adhesive U1 always; Another road is added in the base stage of Q4 through R13, Q4 saturation conduction J1 pick-up voltage is added to load, voltage charges to C3 through R9 → R12 → R11 → R8 → R7 → R6 → R5 → R4 when K1 is closed, when the voltage on the C3 be charged to supply voltage 2/3 the time (3 minutes) U1 3 pin output low level J1 and J2 all disconnect, initial condition is got back in U1 outage again.

The utility model adds the current limliting module on the basis of original 5V stabilized voltage power supply output, limit the requirement that its output current is no more than the 2.0A of standard; In circuit, add the output time delay module, reach the operation requirement that 5V output time maximum is no more than 5 minutes.

The utility model adds the protective circuit of seeing the voltage stabilizing current limliting at original power output end, and power supply output is less than 5 minutes safety specifications when guaranteeing to repair by delay circuit simultaneously; Solve original power module and can not control the hidden danger of the equipment damage that output time causes.

Under the requirement of satisfying Siemens Alternating servomotor calibration power supply output parameter 5V, increase 2.0A current limitation module and the time controlled function in 5 minutes, guarantee that the Star spindle motor can be because of the repairer because the equipment that misoperation causes damage.Under the prerequisite that meets the requirement of Siemens chip mounter Star calibration maintenance technique, fail safe, the ease for use of maintenance of equipment are greatly improved, now except common mains switch 1 is arranged, also be provided with starting switch 2 and carry out power supply output timing, the operating state 4 (as shown in Figure 3) that can check power supply by indicator light 3.

Claims (1)

1. a chip mounter Star axis AC servo motor calibration power supply comprises: connect the transformation module that input 220V exchanges, connect the rectification module of transformation module; It is characterized in that also comprising: the voltage stabilizing that links to each other with rectification module/current limliting module, with the time delay module that voltage stabilizing/the current limliting module links to each other; Time delay module connects 5V output.
