Position correcting device and electronic component handling device provided with the position correcting device

The present invention relates to a position correcting device for position correction of an electronic component, and an electronic component carrying device that carries an electronic component and performs various processes, and performs position correction of the electronic component for various processes.

The electronic component is a component used for an electric product, and is packaged by a semiconductor element or the like. The semiconductor element may be, for example, a discrete semiconductor or an integrated circuit such as a transistor or a diode, a capacitor, or a resistor. The electronic component is completed by various processes such as assembly and inspection. In the case of a semiconductor element, it is subjected to dicing, assembly, bonding and sealing, marking processing, visual inspection, electrical property inspection, classification, and mounting in a subsequent step such as assembly and the like. In the case of electrical characteristic inspection, the terminal on the inspection device side is brought into contact with the electrode of the electronic component, current is supplied, voltage or input signal is applied, and the output of the result is measured.

In order to obtain good electronic components, at least good assembly and inspection are necessary. Therefore, in the various processing, the electronic components are fixed. Important. For example, when the electronic component is deviated from the normal position and the contact between the electrode and the terminal is poor, the electrical property inspection with high accuracy cannot be performed. However, the electronic component supplies the electronic component to the conveyance path by, for example, vibrating feeding in a certain direction and a column posture by vibration, and is sucked by the adsorption nozzle to perform various processes along the conveyance path, or is transferred by the conveyor side. Various treatments are performed, but it is not necessary to carry them in a posture that is consistent with a normal position, or to maintain a posture that consistent with a regular position.

To this end, the position of the electronic component is corrected by the position correcting means before various processes. The position correction device has a collection method and a slide method since the past. In the collection method, the electronic component is placed on the stage for position correction, and the electronic component is brought closer to the center of the stage by the guide portion extending from the square (see Patent Document 1). The position correcting device using the collecting method includes a motor of a power source and a cam mechanism that converts the rotation of the motor into a linear motion, and each of the guide portions is coupled to the driven cam. In addition, the slipping method is an electronic component in which an electronic component is abutted in a hole having a square recess, and a posture conforming to a normal position is obtained by the inner wall of the hole (see Patent Document 2).

In recent years, the demand for electrical products has increased on a worldwide scale, and the production speed of electronic components has been further increased. The processing for position correction of electronic components by assembly engineering or inspection engineering is no exception, and the time required for position correction is expected to be further shortened.

The position correcting device using the collecting method is a variety of transmitting mechanisms such as a cam mechanism between the motor and the guide portion. Each communication mechanism is a communication that achieves a force by causing physical actions of one component to affect the physical actions of other components. For this reason, when the members are not fixedly operated, it is necessary to have a certain degree of instability such as play. This instability imposes limitations on the responsiveness of the communication mechanism. Even if it is operated at a speed exceeding the reactivity, other members cannot follow the action of one member and cannot properly transmit the power. Therefore, the rotational speed of the motor that becomes the power source in the position correcting device using the collecting mode is limited, so that the shortening of the time required for the positional correction of the electronic component is limited.

In the position correcting device using the slipping method, when the insertion speed of the electronic component is increased in the hole having the square recess, the time required for the position correction can be shortened. However, the electronic component is positionally corrected while rubbing against the square recess, so that the electronic component is liable to be damaged once the insertion speed is increased. When the position correction is performed without damaging, the insertion speed has to be limited, and therefore the shortening of the time required for the position correction by the position correcting device using the slip mode is also limited.

The present invention is to solve the problem as described above. The present invention provides a position correcting device capable of shortening the time required for position correction of an electronic component and an electronic component carrying device including the position correcting device without increasing the physical stress applied to the electronic component.

The angle formed is separated by only a predetermined angle α, and one edge of the opposite side of the electronic component is guided to rotate clockwise by the motor, and the other side of the normal position is guided to guide the other side of the electronic component. The other side of the opposite side is rotated in the counterclockwise direction by the above motor, following the above regular The opposite side of the facing edges.

The hole portion may be in a state in which one of the opposite sides guiding the one side of the electronic component is rotated by only a predetermined angle β from one side of the normal position to be guided before and after the electronic component is stored. Angle β < predetermined angle α.

The hole portion may be formed through the base, and may be located on a lower layer of the base to form a bottom surface of the hole portion, and further include a stage that does not move.

The hole portion may be integrally formed with the edge and the bottom surface, and the rotation of the electronic component causes the electronic component to slide against the edge by inertia.

The hole portion may have an angle, and two edges that are in contact with the side of the electronic component and that are in contact with the corner, and have a foreign matter retention portion formed by expanding the hole portion at the corner.

(First embodiment)

(position correction device)

As shown in Fig. 1, the position correcting device 1 according to the first embodiment holds the holding unit 22 to correct the electronic component 4 along the transport path 21 to the correct posture. The correct posture is that when the transportation path 21 performs various processes, the electronic component 4 is placed in the correct position and orientation in the positional relationship between the processing stage and the pre-taken holding portion 22. The holding portion 22 and the processing stage are positioned in advance, and the position correcting device 1 aligns the center of the electronic component 4 with the center of the holding portion 22, and corrects the direction of the electronic component 4 to a predetermined direction. Thereby, when the holding unit 22 transports the electronic component 4 to the processing stage, the electronic component 4 is placed on the processing stage in the correct position and direction.

The electronic component 4 has a square or rectangular shape with a square angle of 0402 size (0.4 mm × 0.2 mm) or 0603 size (0.6 mm × 0.3 mm). The holding portion 22 is a unit that holds the electronic component 4 moving on the transport path 21, such as an adsorption nozzle, an electrostatic chuck, a Bernoulli chuck, or a mechanical chuck, and holds the electron zero by attraction, electrostatic force, or physical engagement. The assembly 4 receives an external force from another device and moves on the transport path 21.

The position correcting device 1 includes a hole portion 11 directly under the conveyance path 21, and receives the electronic component 4 from the holding portion 22 for a short period of time, and then accommodates it in the hole portion 11. The hole portion 11 has an opening toward the transport path 21 directly above, which is wider and has a larger bottom area than the electronic component 4. The hole portion 11 houses the electronic component 4 and moves in a horizontal direction orthogonal to the depth.

The electronic component 4 slides in the oscillating hole 11 by the law of inertia, and is guided by the edge of the hole 11 to approach the positive of the electronic component 4. Position 12 (see Figure 2). The normal position 12 is a region in which the electronic component 4 in the correct posture is projected toward the hole portion 11, and the electronic component 4 corresponds to a rectangle in which the four corners are at right angles and the opposite sides are parallel. The hole portion 11 is an adjustment setting place, a shape, and a movement range such that the edges of the edges abutting on the electronic component 4 are respectively along the corresponding sides of the normal position 12. Therefore, the electronic component 4 is corrected to the normal position 12 during the guiding process by the edge. In the process of attracting the electronic component 4, the edges of the electronic component 4 are aligned along the edge of the hole 11, and the direction of the electronic component 4 can also be corrected.

The position correcting device 1 includes a cylindrical base 14 that faces a conveyance path 21 and a motor 15 that rotates the base 14. The base 14 is a rotating shaft 16 that supports a plane orthogonal to the motor 15. The hole portion 11 is formed on the plane of the chassis 14 and faces the opening toward the conveyance path 21 side. The hole portion 11 may also be formed by assembling four blocks 13 standing on the plane of the base 14 around a region to form a space surrounding the block 13, or may be recessed in the plane of the base 14.

As shown in Fig. 2, the hole portion 11 is formed at a position deviated from the rotating shaft 16. The motor 15 is a moving base 14. Therefore, the hole portion 11 also moves around the rotation shaft 16. The hole portion 11 is an area including the regular position 12 of the electronic component 4, and may be enlarged by swing to often completely include the regular position 12.

The electronic component 4 also has the possibility of being offset from the normal position 12 toward the clockwise direction of the rotary shaft 16, and may also be biased toward the counterclockwise direction. When the motor 15 rotates the base 14 in the counterclockwise direction, the hole The portion 11 is rotationally moved in the counterclockwise direction such that the electronic component 4 that is offset toward the clockwise direction follows the normal position 12. When the motor 15 rotates the chassis 14 in the clockwise direction, the hole portion 11 is rotationally moved in the clockwise direction, so that the electronic component 4 offset in the counterclockwise direction follows the normal position 12.

When the position correcting device 1 can recognize in advance that the electronic component 4 is biased toward the clockwise direction or the counterclockwise direction, it is only necessary to rotate the hole portion 11 toward the side opposite to the offset direction of the electronic component 4. can. For example, the position correcting device 1 includes a camera or the like that can detect the deviation of the electronic component 4, and rotates the hole portion 11 toward the side opposite to the offset direction of the electronic component 4.

Further, the motor 15 may rotate the chassis 14 in the clockwise direction and the counterclockwise direction to swing the hole portion 11 back and forth. It is not necessary to detect the misalignment direction of the electronic component 4, that is, the electronic component 4 can follow the normal position 12.

The hole portion 11 has at least four edges 11a, 11b, 11c, and 11d corresponding to the four sides of the electronic component 4. The set of edges 11a and 11b and the set of edges 11c and 11d are opposed to each other with a normal position 12. The other edges are retracted to a position separated from the regular position 12 to the extent that they do not obstruct the electronic component 4. That is, the hole portion 11 has a polygonal shape of a quadrangular shape or more. Curved parts are also available outside the four edges.

First, the hole portion 11 has a first edge 11a and a second edge 11b which are in contact with the corner 11e at one place. Further, the hole portion 11 has the third contact from the corner 11e through the center of the hole portion 11 and the corner 11f located at the other corner of the diagonal The edge 11c and the fourth edge 11d. The corners 11e and 11f are right angles. The first edge 11a and the third edge 11c are expanded by a predetermined angle α in parallel with the direction separated from the rotation shaft 16. Further, the second edge 11b and the fourth edge 11d are also expanded only by a predetermined angle α only in parallel.

When the hole portion 11 is adjusted in the direction and size and is wound in the counterclockwise direction, when the first edge 11a follows the side ab of the normal position 12 and is wound in the clockwise direction, the third edge 11c follows the side ab of the normal position 12. Side cd. In other words, when the hole portion 11 is adjusted in the direction and size and is wound in the counterclockwise direction, when the second edge 11b follows the side ab of the normal position 12 and is wound in the clockwise direction, the fourth edge 11d follows the side bc of the regular position 12. .

Further, the hole portion 11 has a foreign matter retention portion 11g at a corner 11e formed by abutting the first edge 11a and the second edge 11b at a corner of the edge abutting on the electronic component 4. The foreign matter retention portion 11g is a space for trapping foreign matter different from the electronic component 4 such as dust, and is formed by expanding the corner portion of the edge that abuts on the electronic component 4 by widening the hole portion 11. The foreign matter retention portion 11g can be formed at an angle 11e where the first edge 11a and the second edge 11b abut, and an angle 11f where the third edge 11c and the fourth edge 11d abut each other.

The specific operation of the position correcting device 1 as described above will be described based on Figs. 3 to 6 . As shown in Fig. 3, the hole portion 11 is an initial state in which the first edge 11a is rotated from the one side ab of the normal position 12 toward the clockwise direction by only the angle β. Angle β < angle α. Only the pre-winding angle β is such that the electronic component 4 that can shift the position does not collide with the edge of the hole portion 11. In the initial state, each edge 11a of the hole portion 11 is 11b, 11c and 11d are separated from the regular position 12. Therefore, the electronic component 4 does not come into contact with the edge of the hole portion 11, and can enter the hole portion 11.

Next, as shown in FIG. 4, the motor 15 is in an initial state from the hole portion 11, and the hole portion 11 is wound in the counterclockwise direction only at an angle β at which the first edge 11a and the one side ab of the normal position 12 coincide. At this time, when the electronic component 4 is displaced from the normal position 12 in the clockwise direction, the electronic component 4 slides in the hole portion 11 and comes into contact with the first edge 11a and the second edge 11b which are oncoming, and further The first edge 11a and the second edge 11b that are wound are pressed into the normal position 12.

Further, as shown in Fig. 5, the motor 15 winds the hole portion 11 only in the clockwise direction by the opening angle α of the first edge 11a and the third edge 11c, and causes the third edge 11c to follow the opposite side cd of the regular position 12. At this time, when the electronic component 4 is displaced from the normal position 12 in the counterclockwise direction, the electronic component 4 slides in the hole portion 11, and abuts against the oncoming third edge 11c and the fourth edge 11d, and further The third edge 11c and the fourth edge 11d that are wound are pressed into the normal position 12.

Further, as shown in Fig. 6, the motor 15 rotates the hole portion 11 by an angle (α - β) in the counterclockwise direction, returns the hole portion 11 to the initial state, and releases the electronic component 4 and the hole at the regular position 12. The third edge 11c and the fourth edge 11d of the portion 11 are engaged. Thereafter, the holding unit 22 holds the electronic component 4 again and is detached from the hole portion 11.

When there is a foreign matter in the hole portion 11 during the continuous driving, the foreign matter is guided to the foreign matter retention portion 11g by the first edge 11a and the second edge 11b, and is stored in the foreign matter retention portion 11g. Therefore, foreign matter is taken from the electronic zero group The regular position 12 of the member 4 is removed, and adhesion to the electronic component 4 to be accommodated next can be suppressed.

(electronic component handling device)

The electronic component handling device of the position correcting device 1 as described above will be described.

Fig. 7 is a top view of the electronic component handling device, and Fig. 8 is a side view of the electronic component handling device.

The electronic component conveying device 2 shown in FIGS. 7 and 8 includes a holding portion 22 for carrying the electronic component 4. The electronic component conveying device 2 has a turntable 23 and a direct drive motor 24 that intermittently rotates the turntable 23. A plurality of holding portions 22 are attached to the periphery of the turntable 23 at a circumferential position or the like. The conveyance path 21 is formed by the rotation of the turntable 23, in other words, the movement locus of the holding portion 22 rotated by the turntable 23. The arrangement interval of the holding portions 22 is equal to the rotation angle of one of the turns of the turntable 23, and all the holding portions 22 are sequentially stopped at the same stop position of each angle.

The holding portion 22 has an axis orthogonal to the expansion plane of the turntable 23, and is suspended downward from the turntable 23. The turntable 23 has a bearing on the outer edge, and the holding portion 22 is supported by the bearing so as to be movable up and down. The holding portion 22 is, for example, an adsorption nozzle. The adsorption nozzle is a hollow tube inside. The inside of the tube communicates with the hose through a pneumatic circuit of a vacuum generating device (not shown). The holding portion 22 formed by the adsorption nozzle adsorbs the electronic component 4 by the generation of the negative pressure of the vacuum generating device, and detaches the electronic component 4 by vacuum destruction.

The position correcting device 1 is disposed directly below the outer edge of the turntable 23 The square is such that the hole portion 11 is located directly below the stop position of the holding portion 22. The advancing and retracting drive unit 25 is provided on the side opposite to the hole portion 11 with the conveyance path 21 interposed therebetween. The advancing and retracting drive unit 25 includes a lever 25b that pushes the holding portion 22 downward, and an actuator 25a that applies a thrust to the lever 25b. The advancing and retracting drive unit 25 operates the actuator 25a to advance the rod 25b toward the holding portion 22 such that the tip end of the rod 25b abuts against the rear end of the holding portion 22, and further advances the rod 25b to move the holding portion 22 toward the hole portion 11. Further, the advancing and retracting drive unit 25 further includes a compression spring 25c that pushes the holding portion 22 upward, and when the thrust of the lever 25b is released by the actuator 25a, the compression spring 25c pushes the holding portion 22 upward.

In addition to the position correcting device 1, around the turntable 23, various processing units 3 are disposed at the stop position of the holding portion 22. As the processing unit 3, for example, a test unit, a feeder, a marking unit, an appearance inspection unit, a classification level unit, a tape winding unit, a defective product discharge unit, and the like, which are disposed on the downstream side in the conveyance direction, are exemplified.

The test unit has contacts for energizing the electronic components 4. In a state where the positional relationship between the electronic component 4 and the holding portion 22 is correctly corrected by the position correcting device 1, the electrodes of the electronic component 4 are in contact with the contacts. The test unit is a current flowing through the contact member to the electronic component 4, or applying a voltage to measure electrical characteristics such as voltage, current, resistance or frequency of the electronic component 4.

The feeder is a device that supplies the electronic component 4 to the electronic component handling device 2. The feeder is, for example, a combined circular vibrator and a linear supply vibration feedback device, and the entire series of electronic components 4 are continuous It is conveyed to the end of the conveyance path 21 immediately below the peripheral end of the turntable 23.

The marking unit is a lens for laser illumination adjacent to the electronic component 4, and the laser is irradiated onto the electronic component 4 for marking. The electronic component 4 that correctly corrects the positional relationship with the holding portion 22 with respect to the borrowing position correcting device 1 is marked at the correct position and range. The visual inspection unit includes a camera and a photographing electronic component 4, and checks the electrode shape of the electronic component 4, the surface defects, damage, dirt, foreign matter, and the like from the image. The classification level unit classifies the electronic components 4 into defective products and good products based on the electrical characteristics and visual inspection results, and discharges them according to their classification. The tape wrapping unit is an electronic component 4 that is judged to be a good product. The defective product discharge unit discharges the unwrapped electronic component 4 from the electronic component conveying device 2.

The electronic component conveying device 2 holds the electronic components 4 supplied from the feeder with the holding portion 22, and carries the electronic components 4 along the conveyance path 21 by the respective processing units 3. When the holding portion 22 of the electronic component 4 is stopped and stopped right above the position correcting device 1, the advancing and retracting driving portion 25 pushes the holding portion 22 toward the position correcting device 1. The holding portion 22 is lowered toward the hole portion 11 by the advancing and retracting driving portion 25, and when the electronic component 4 is inserted into the hole portion 11, the electronic component 4 is detached from the inside of the hole portion 11. When the holding portion 22 is a suction nozzle, when the suction force is released by vacuum destruction or atmospheric destruction, the electronic component 4 is placed on the bottom of the hole portion 11.

When the electronic component 4 is housed in the hole portion 11, the position correcting device 1 causes the hole portion 11 to swing back and forth, and performs position correction for fitting the electronic component 4 to the normal position 12. Once the position correction is completed At this time, the holding portion 22 holds the electronic component 4 in the hole portion 11. When the holding portion 22 is a suction nozzle, the vacuum generating device sucks the electronic component 4 at the tip end of the adsorption nozzle. The advancing and retracting drive unit 25 lifts the holding force of the compression spring 25c to the holding portion 22 that holds the electronic component 4, and releases the holding force 22 of the electronic component 4 after the holding position is corrected.

After passing through the position correcting device 1, the position-corrected electronic component 4 becomes a follow-up test unit, a marking unit, an appearance inspection unit, a classification level unit, and a tape winding unit. At this time, the electronic component 4 that has been correctly corrected in the positional relationship with the holding portion 22 also correctly maintains the positional relationship with the processing unit 3 such as the test unit, and performs processing with reliability.

(Effect)

As described above, the position correcting device 1 includes the motor 15 that rotates the rotating shaft 16 in the clockwise direction and the counterclockwise direction, and the motor 15 is formed on the base 14 centered on the rotating shaft 16, and is wider than the electronic component 16, and houses the electronic zero. The hole portion 11 of the assembly 4. The hole portion 11 is formed at a position offset from the rotating shaft 16, and is reciprocated by the motor 15, and the inner electronic component 4 is guided to the predetermined position by the edge of the hole portion 11.

The position correcting device 1 only needs to reciprocate the moving hole portion 11, and it is not necessary to provide a communication force between the base 14 and the motor 15 in which the hole portion 11 is formed, or a plurality of transmission mechanisms for changing the direction of the force. . For this reason, the reactivity of the swing operation of the hole portion 11 is extremely high, and the swing operation of the hole portion 11 can be performed at high speed. Therefore, according to the position correction Set to 1 to shorten the time required for position correction.

Further, the hole portion 11 is such that both ends of the opposite sides of the electronic component 4 are guided, and the angle formed by the opposite sides is expanded by a predetermined angle. Further, one edge of the opposite side of the guiding electronic component 4 is rotated clockwise by the motor 15, and follows one side of the area occupied by the electronic component 4 of the regular position 12, and the electronic component 4 is guided. The other edge of the opposite side of the one side is rotated by the motor 15 in the counterclockwise direction, and follows the opposite side of the one side of the area occupied by the electronic component 4 at the regular position 12 of the division. Thereby, the positional correction of the position and direction of the electronic component 4 can be performed with high precision.

Further, the hole portion 11 is a corner 11e that is in contact with both edges abutting on the side of the electronic component 4, and has a foreign matter retention portion 11g formed by the expansion hole portion 11. Thereby, the foreign matter in the hole portion 11 is guided to the foreign matter retaining portion 11g, and adhesion to the electronic component 4 can be prevented.

(Second embodiment)

(electronic component handling device)

The electronic component conveying device 2 according to the second embodiment will be described in detail with reference to the drawings. In the position correcting device 1 and the electronic component conveying device 2, the same configurations and the same functions as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted.

As shown in Fig. 9, the distance between the holding portion 22 that releases the downward force by the advancing and retracting drive unit 25 and the bottom surface of the hole portion 11 is D1, and the thickness of the electronic component 4 is T1. The advance and retreat drive unit 25 is in the electronic component 4 When the hole portion 11 is housed, the holding portion 22 is lowered by only the distance (D1-T1-D2). When the depth of the hole portion 11 is D3, 0 < D2 ≦ D3, and D2 is larger than zero and within the depth of the hole portion 11.

Further, when the position correcting device 1 performs position correction of the electronic component 4, the holding unit 22 holds the state of the electronic component 4. When the holding portion 22 is a suction nozzle, the holding portion 22 maintains the suction force in advance. In other words, the electronic component 4 accommodated in the hole portion 11 is in a state of not floating on the bottom surface of the hole portion 11, but is kept floating in the air inside. The position correcting device 1 is in a state in which the electronic component 4 floats in the air inside the hole portion 11, and the hole portion 11 is oscillated back and forth to perform positional correction of the electronic component 4.

As shown in Fig. 10, the hole portion 11 abuts the edge of the electronic component 4, thereby imparting a moving force in a horizontal direction orthogonal to the direction in which the attraction force or the electrostatic force holding force acts. Thereby, the moving force causes the electronic component 4 to rise horizontally with respect to the holding portion 22, so that the electronic component 4 moves to follow the normal position 12.
