Description

TECHNICAL FIELD [0001] The present invention relates to a component mounting apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a component mounting apparatus and method, and more particularly, to a component mounting apparatus and method capable of mounting a plurality of components on a substrate corresponding to a shape of a pickup head.

Generally, the component mounting apparatus is a device that performs an operation of mounting an electronic component (hereinafter referred to as a " component ") such as an integrated circuit, a high-density integrated circuit, a diode, a capacitor, .

Such a component mounting apparatus includes a component supply module for supplying components to be mounted on a substrate, a substrate transport module for transporting the substrate so that components supplied from the component supply module can be mounted, A head assembly having a nozzle spindle for mounting picked-up parts on a substrate, a head assembly for picking up parts in a part pick-up area to be supplied with the parts, And a horizontal movement module for moving the head assembly in the X and Y directions so as to be mounted in the component mounting area, which is a preset position.

Each component supplied to such a component mounting apparatus is manufactured by a specific manufacturer. In the case of different components, not only a larger standard difference is shown, but even a component having the same specification exhibits a slight difference in standards depending on the manufacturer.

On the other hand, when the component 2 is picked up from the feeder, the component 2 is supplied to the feeder 1 at a predetermined interval, as shown in Fig. 1A, And the parts 2 existing in the uppermost row of each row are picked up by a plurality of absorption units (spindle) 4 formed on the pick-up head 3 provided in a direction substantially orthogonal to each feeder 1. [

The picked-up parts 2 are mounted at predetermined positions on a substrate (not shown).

Subsequently, after the parts picked up by the pick-up head 3 are exhausted, the feeder 1 advances the feeder 1 forward as shown in FIG. 1B so that the next component is positioned on the pick-up head 3 .

The interval at which the feeder 1 moves coincides with the interval of the parts 2 fed by the feeder 1 and is set to move by one component interval unit at a time.

The pick-up head 3 can simultaneously or simultaneously adsorb the component 2 from the plurality of feeders 1.

Next, as shown in Fig. 1C, when the parts 2 existing in the next higher row of the respective rows of the plurality of feeders 1 are exhausted, the feeder 1 advances again by the interval of the parts and is present in the third row of each row So that the component 2 is aligned with the position of the pick-up head 3.

In the conventional component mounting apparatus thus provided, components are supplied from a plurality of feeders at the same time, so that if an abnormality occurs in one feeder among a plurality of feeders, a problem may arise in component pickup.

2A to 2D, the pick-up head 3 and the adsorption unit 4 are arranged along the longitudinal direction of the feeder 1 so that a plurality of parts 2 In the component mounting apparatus is picked up.

However, as shown in Figs. 2B and 2C, this configuration is set to move in units of one component at a time because the conventional feeder 1 is used as it is.

That is, as shown in FIG. 2B, after the three parts 2 are sucked and mounted on the substrate in the previous step, the feeder 1 has to move the three component parts in order to suck the next three parts 2 , The feeder 1 according to the conventional configuration is set to move by only one component interval at a time. Therefore, the feeder 1 is moved to a desired position by repeating the movement and the stopping process three times in total.

In this case, as shown in the graphs shown at the bottom of each of Figs. 2B and 2C, the feeder 1 continues to move through the constant-speed steps B1 and B2 via the acceleration steps A1 and A2, , C2 to complete the movement once.

Finally, the change in speed with time of the feeder 1 for moving the three component intervals is as shown in Fig. 2D. That is, the acceleration-constant-speed-deceleration step is repeated three times in total to move the feeder 1 to a predetermined position.

This causes an unnecessarily long time for the feeder to move, which results in a decrease in work efficiency and an increase in cost due to deterioration in productivity.

In addition, since the distance that one feeder moves at a time is fixed, there is a disadvantage that the structure of the entire feeder must be changed in order to change it.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide a component mounting apparatus and a method in which movement efficiency at the time of moving is improved according to a predetermined component interval.

Another object of the present invention is to provide a component mounting apparatus and method that can variably control the movement distance of a feeder.

Hereinafter, a component mounting apparatus according to an embodiment of the present invention will be described with reference to FIGS. 3A and 3B. FIG. 3A and 3B are views showing the configuration and operation of a component mounting apparatus according to an embodiment of the present invention.

A component mounting apparatus according to an embodiment of the present invention includes a feeder unit 10 for feeding a plurality of components 11 arranged in a line and a plurality of components 11 along the longitudinal direction of the feeder unit 10, A pick-up header section 20 for picking up a part of the pick-up unit 11 in the pickup unit, and a drive section for moving the feeder section 10 in the longitudinal direction, And the feeder unit 10 moves with one acceleration period and one deceleration period.

The feeder unit 10 feeds a plurality of parts 11. Unlike the conventional component mounting apparatus described with reference to Figs. 1A and 1B, the feeder unit 10 according to the present embodiment is provided with the components 11 arranged in a row. That is, the parts 11 are arranged in a row in the vertical direction on the figure 3a, and the parts 11 are supplied to the pickup header part 20. [

The type of the component 11 supplied by the feeder unit 10 is not limited, and various types of components that can be mounted on the substrate, for example, a diode, a capacitor, a resistor, and the like may be included.

An alignment mark 12 may be formed on one side of the feeder 10 in the longitudinal direction. The alignment mark 12 enables the operator to visually confirm whether the feeder unit 10 is normally moved or by using a camera unit or the like and can serve as a comparison factor for determining the size of the pickup header unit 20 .

The feeder portion 10 can move upward by a predetermined distance as shown in FIG. 3A.

That is, the pick-up head 20 picks up or grips the pick-up unit 11 (five parts on the figure 3a) and mounts the pick-up unit 20 on the substrate, As shown in FIG. 3B, the feeder unit 10 is moved in the upward direction by a distance corresponding to the pickup unit PU so that the supplied component 11 (five components in FIG. 3B) can be sucked or held again Move to distance.

The above process is repeated so that the feeder unit 10 can feed the component 11 to the pick-up head unit 20 while continuously moving by the movement distance corresponding to the pick-up unit PU.

The moving distance of the feeder portion 10 can be changed according to the type and / or standard of the component 11. [ Particularly, in determining the moving distance of the feeder unit 10, the pick-up unit PU, that is, the number of parts picked up at which one picks up a part at a time is multiplied by the distance corresponding to one component interval The moving distance can be determined.

That is, the final moving distance of the feeder unit 10 can be determined to be 25 when the pick-up unit PU is 5, and the interval of each component is 5.

The final travel distance of the feeder portion 10 may be determined by various methods. That is, information on the final travel distance of the feeder unit 10 may be included in one forward command received by the driving unit that drives the feeder unit 10, and the number of times of the forward commands received by the driving unit May be calculated separately in the driving section by multiplying the respective component intervals.

For example, if the advancing command of the feeder unit 10 received by the driving unit is received ten times and the interval of each of the parts is 5, the final movement of the feeder unit 10 The distance may be determined as 50.

The method of calculating or transmitting / receiving the final moving distance of the feeder unit 10 is not limited to the above-described configuration, and various other methods may be used.

The pick-up head 20 picks up a part 11 of the plurality of parts 11 corresponding to the pick-up unit PU along the longitudinal direction of the feeder part 10 and mounts the parts 11 on the substrate.

The pickup header section 20 may include an adsorption unit 21 that is individually adsorbed to each of the parts 11.

The structure of the adsorption unit 21 for adsorbing or holding the component 11 is not limited and the adsorption unit 21 may be provided with an air flow path (not shown), for example, And the air passage may be connected to the negative pressure air supply unit and the static pressure air supply unit.

That is, after the adsorption unit 21 is aligned with the component 11 positioned on the upper surface of the feeder unit 10, the adsorption unit 21 applies negative pressure to the air flow path of the adsorption unit 21, So that it can be adsorbed.

The pick-up header unit 20 moves the adsorbed component 11 to the upper side of the substrate and then applies a positive pressure to the air flow path of the adsorption unit 21 to mount the component 11 on the substrate, Is detached from the unit 21 and mounted on the substrate.

The pick-up header section 20 is fixed at a predetermined pick-up position and can feed the component 11 to the pick-up header section 20 while the feeder section 10 is continuously moved.

On the other hand, the pick-up header section 20 picking up the component 11 can be provided so as to be movable in the front and rear direction and / or in the left and right direction on a predetermined plane by a horizontal movement mechanism (not shown). The horizontal movement mechanism may include an X-axis gantry (not shown) that horizontally moves the pickup header 20 in the X-axis direction and a Y-axis gantry (not shown) that horizontally moves the pickup header 20 in the Y-axis direction.

The pick-up head 20 can be coupled to the X-axis gantry so as to be horizontally movable along the X-axis gantry. In this case, both ends of the X-axis gantry are connected to a Y-axis gantry And can be mounted horizontally.

Accordingly, when the X-axis gantry moves along the Y-axis gantry, the pick-up head 20 mounted on the X-axis gantry moves horizontally in the Y-axis direction. In addition, the pickup head 20 horizontally moves along the X-axis gantry in the X-axis direction.

Thus, the pick-up head 20 moves in the X-axis and Y-axis directions, sucks the component from the feeder 10, moves again in the X-axis and Y-axis directions, do.

As described above, the pick-up unit PU of the pick-up head 20 can be determined by the number of the pick-up units 21 provided in the pick-up header 20. That is, when the number of the suction units 21 provided in the pickup head 20 is increased, the number of the parts 11 picked up at one time also increases, and the pickup unit PU increases.

The moving distance of the feeder unit 10 determined in accordance with the pick-up unit PU can be determined in consideration of the number of the suction units 21 provided in the pickup header unit 20 and the interval between the suction units 21 .

The interval of the adsorption unit 21 is set to coincide with the interval of the parts 11 fed by the feeder unit 10. [

Hereinafter, a component mounting apparatus according to another embodiment of the present invention will be described with reference to Figs. 4A and 4B. FIGS. 4A and 4B are diagrams illustrating the configuration and operation of a component mounting apparatus according to another embodiment of the present invention.

The component mounting apparatus according to another embodiment of the present invention has the same configuration as in the previous embodiment, but the number of adsorption units 21 can be varied.

That is, as shown in FIGS. 4A and 4B, the number of the pickup units 21 provided in the pickup header unit 20 can be set differently, so that the number of components that can be picked up at one time can be adjusted.

Accordingly, the pick-up unit PU determined by the number of the suction units 21 can also be increased or decreased.

Next, the process of moving the feeder 10 according to the embodiments of the present invention will be described with reference to FIGS. 5 and 6. FIG. FIG. 5 is a view showing a variation in speed of a feeder constituting a component mounting apparatus according to the embodiments of the present invention with time, FIG. 6 is a diagram showing a feeder constituting the component mounting apparatus according to the embodiments of the present invention, Fig. 8 is a diagram showing the comparison of the speed variation of the feeder constituting the component mounting apparatus according to the time transition.

As described above, unlike the conventional component mounting apparatus, in which the feeder unit 10 moves according to the final movement distance determined by various methods, the component mounting apparatus moves by one component interval in one movement. The feeder unit 10 moves along the final movement distance at a time.

2D, in the conventional component mounting apparatus, in order to move the three component intervals, the speed change of the feeder 1 over time is divided into the acceleration-constant-deceleration steps The feeder unit 10 of the component mounting apparatus according to the present embodiments is moved over the predetermined time period E1, E2, and E3), and completes the movement after passing through one deceleration section (F).

In other words, unlike the prior art, since the feeder unit 10 is configured to move all three component parts at a time, it is unnecessary to repeat the deceleration and acceleration sections to delay the movement time.

This is clearly illustrated in the comparative graph of FIG. That is, the upper graph shows the movement of the conventional feeder portion 1, and the lower graph shows the movement of the feeder portion 10 according to the present embodiments.

In moving the same moving distance, for example, three component intervals, the moving time of the feeder unit 10 according to the present embodiments is greatly shortened.

In order to achieve this, as described above, it is possible to calculate the final movement distance by calculating the final movement distance calculated in the driving unit for driving the feeder unit 10, or by summing the number of the forward commands received by the driving unit.

As described above, the component mounting apparatus according to the present embodiment can provide a component mounting apparatus capable of significantly reducing the movement efficiency, that is, the movement time, when the feeder unit 10 moves according to the predetermined component interval. It is possible to provide a component mounting apparatus capable of variably controlling the moving distance of the component (10).

Hereinafter, a component mounting method according to an embodiment of the present invention will be described with reference to FIG. 7 is a flowchart showing a component mounting method according to an embodiment of the present invention.

The method for mounting a component according to an embodiment of the present invention includes a step S11 of inputting a forward command for moving the feeder unit by a basic distance, a step S12 calculating a travel distance of the feeder unit (S13) of moving the feeder section by the movement distance, and a step (S14) of picking up a component in the pickup header section, wherein the feeder section moves with one acceleration section and one deceleration section .

First, the control unit inputs a forward command for moving the feeder unit by the basic distance (S11). As described above, the control unit can send out the final movement distance calculated by the driving unit that drives the feeder unit, or send the forwarding command one or more times to the driving unit. That is, the forward command may be inputted in plural, and one forward command may include a predetermined basic distance (interval between parts).

Next, the movement distance of the feeder portion is calculated by summing the inputted forward commands (S12). The travel distance may be calculated by multiplying the number of forward commands entered by the plurality of routes by the basic distance. For example, when five forward commands are inputted from the control unit to the driving unit and the basic distance is 5, the final calculated movement distance corresponds to 25.

Subsequently, the feeder portion is moved by the movement distance (S13), and the component mounting process is performed by sucking the component in the pickup header portion (S14).

(S15) of forwarding a completion command to the control unit from the feeder unit, and initializing the movement distance of the feeder unit (S16) after the step of adsorbing the component.

As described above, the final travel distance of the feeder unit can be calculated by summing a plurality of forward commands. The forward command received is accumulated until the forward completion command is sent to the control unit. Thereafter, when a forward complete command is transmitted from the feeder unit or the driving unit, the accumulated forward command is deleted to initialize the travel distance value.

Thereafter, when the forward command is inputted again, the travel distance can be newly calculated by summing the forward command again.

As described above, the feeder unit moves a moving distance by repeating the process of moving by the distance of the components, so that the feeder unit does not have a plurality of acceleration and deceleration zones, but moves the entire summed movement distance by one movement process, And has one acceleration section and one deceleration section before and after the constant velocity section at the time of negative movement.

As a result, it is possible to prevent the delay of the operation time due to the unnecessary increase or decrease of the speed of the feeder portion, and it is possible to quickly move the feeder portion and proceed with the mounting operation.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, You will understand. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
