Description

Parallel method and mechanism for packaging electronic component and coating adhesive on carrier tape

Technical Field

The present invention relates to electronic component packaging technology, and is especially parallel method and mechanism for packaging electronic components and applying adhesive onto carrier tape.

Background

In the known technology of packaging electronic components with carrier tape, in order to solve the inconvenience and energy waste resulted from the conventional pre-coating of the adhesive layer on the upper tape, the applicant is led to the CN103213701A patent to provide a technical content of delaying the application of the adhesive layer until the actual packaging operation of the electronic components is performed, so that the structure of the upper tape does not need to be pre-coated with the adhesive layer and attached with the release layer for protection, thereby greatly reducing the manufacturing cost of the upper tape and having obvious economic effects.

In the prior art, the adhesive is applied to the surface of the lower tape by a known dispensing technique to adhere and combine with the upper tape, so as to reduce the control requirement of adhesive coating, and the application method of outputting the adhesive on the surface of the lower tape at a fixed flow rate can reduce the control requirement of application.

Specifically, when packaging electronic components with a carrier tape, it is necessary to place the electronic components in the chamber of the lower tape first, and in order to match the placement of the electronic components, the known technique is to move the lower tape intermittently so as to place the electronic components in the chamber of the lower tape within a short dwell time when the movement of the lower tape is stopped, but since the application of the adhesive is a continuous output at a fixed flow rate, the adhesive is continuously output during the dwell time of the lower tape, and thus the local application is excessive, which is wasteful, and has a negative effect on the quality of the package.

Disclosure of Invention

It is therefore a primary object of the present invention to provide a method for packaging electronic components in parallel with the application of adhesive on a carrier tape, which allows for an intermittent advance movement between the continuous dispensing of adhesive and the packaging operation, which avoids concentrated application of the continuously dispensed adhesive to fixed locations on the carrier tape during short down times for the insertion of the electronic components, and which, in addition to avoiding excessive application of adhesive, ensures that the quality of the packaging is not affected by excessive amounts of adhesive.

The present invention provides a method for packaging electronic components and applying an adhesive on a carrier tape, which is characterized in that a first tape is moved through an application unit and a bonding unit in different motion states, so that an adhesive can be continuously applied to the first tape in the application unit, and the first tape and a second tape can be intermittently and stepwise bonded in the bonding unit.

Wherein the first tape is continuously advanced through the application unit in a first motion while the application unit applies the adhesive to the first tape, and thereafter the first tape is intermittently advanced through the bonding unit in a second motion.

And the speed of the first movement is made to be greater than that of the second movement, so that the length of a standby section of the first belt between the applying unit and the combining unit is increased and the standby section is unfolded in a supported manner to avoid the standby section from being overlapped; in order to avoid the length of the standby segment increasing beyond the range of the stretch, the application unit can apply the adhesive in a plurality of successive application procedures, and the successive application procedures are separated by a pause.

The continuous movement time of the first movement is the same as the execution time of the application programs, and the interruption time is longer than the interruption time of the intermittent movement of the second movement, so that the adhesive application can be centralized, and the number of the application programs can be reduced.

In addition, in order to prevent the adhesive from overflowing to an unintended position or adhering, the adhesive on the standby section is dried, and the drying may be performed immediately after the application process.

The present invention also provides a parallel mechanism for packaging electronic components and applying adhesive on a carrier tape, which can be used for implementing the parallel method for packaging electronic components and applying adhesive on a carrier tape.

The present invention provides a parallel mechanism for packaging electronic components and applying adhesive on a carrier tape, comprising the applying unit, the combining unit, the first tape and the second tape, wherein the applying unit has at least one applying end for outputting the adhesive; the combination unit is separated from the application unit and is positioned at different spatial positions; the first belt is a continuously extending belt body, passively passes through the applying unit and the combining unit in sequence from a first supplying end, reaches a collecting end, and enables a combining surface on one side to face the applying end when passing through the applying unit, the adhesive can be applied to the combining surface by the applying unit through the applying end, the first belt passes through the applying unit continuously in a first movement when the applying unit applies the adhesive to the combining surface, and the first belt passes through the combining unit intermittently in a second movement when passing through the combining unit; the second tape, also a continuously extending tape, passively passes through the joining unit from a second supply end, then passes through the collecting end, and passes through the joining unit with one side tape surface facing the joining surface, and joins the first tape and the second tape with the adhesive on the joining surface.

The first movement and the second movement of the first belt are caused by different powers, that is, a first power part provides power to drive the first belt to perform the first movement, and a second power part provides power to drive the first belt to perform the second movement.

The second belt moves synchronously with the first belt moving through the combining unit with the second movement, and the first belt and the second belt are driven simultaneously by the second power part to achieve synchronous movement.

In order to support the standby section of the first belt between the application unit and the combination unit and avoid the standby section from freely hanging down to influence the use, a stretching part is abutted against the standby section to stretch the first belt by being supported.

When the first movement speed is higher than the second movement speed, the length of the standby section is increased, and in response to the increase of the same length, the stretching part is made movable to move in response to the increase of the length of the standby section, so that the support provided for the first belt is ensured.

In order to simplify the mechanism, the first power portion can drive the first belt to perform the first motion via the movable stretching portion.

The first power part uses fluid pressure as the fluid pressure cylinder part of the power source, and the expanding part is arranged on the output shaft of the first power part, when the output shaft of the first power part extends outwards, the expanding part is displaced while driving the first belt to perform the first motion so as to maintain the butt joint between the expanding part and the standby section, and when the output shaft of the first power part retracts inwards actively or passively, the first belt stops the first motion, but the second motion is maintained, so that the length of the standby section is reduced, and at the same time, the retracting of the output shaft of the first power part is synchronized with the second motion so as to maintain the support of the expanding part on the standby section in length reduction.

The invention has the beneficial effects that:

The drying part 13 has a rectangular box 131 fixed on the cantilever 117, an inlet 132 and an outlet 133 respectively disposed on two ends of the long axis of the box 131 to communicate the space in the box 131 with the outside, a plurality of heat pipes 134 are equally disposed on the bottom of the box 131 and below the horizontal plane of the inlet 132 and the outlet 133, and two heat pipes can heat the air by the heat energy of the heat pipes 134 to generate heat convection, or increase the convection of the air accelerated by an external air flow generator, or increase the energy of solvent molecules by the liquid solvent in the microwave oscillation adhesive to accelerate the dissipation speed of the solvent molecules in gaseous state.

Referring to fig. 5, the combining unit 14 is disposed on the base 111 and between the electronic component placing and processing area 114 and the first reel 112.

The first power portion 15 is a fluid pressure cylinder device using fluid pressure as a power source, and is fixed on the cantilever 117.

The second power portion 16 is a known driving technique such as a motor, and is applied to a driving means of an electronic component packaging technique, which is a category of the known technique, and is a detailed technical content of the second power portion 16, which is not an exception.

Referring to fig. 6, the stretching portion 17 has a roller 171, which is rotatably disposed at the end of the output shaft 151 of the first power portion 15, and can linearly reciprocate along with the extension and contraction of the output shaft 151 of the first power portion 15.

Referring to fig. 8, the actuating portion 18 is disposed between the applying unit 12 and the third reel 116, and has a support plate 181 fixed on the column 115, a cylindrical fixed side 182 with two ends suspended on the support plate 181, a block-shaped movable side 183 disposed between the fixed side 182 and the support plate 181 and slidably disposed on the support plate 181 relative to the fixed side 182, and an actuating fluid cylinder 184 fixed on the support plate 181 and capable of providing power to drive the movable side 183 to move toward or away from the fixed side 182 in a reciprocating linear manner.

The first tape 19 and the second tape 20 are components of a known carrier tape, and can accommodate electronic components in a plurality of chambers (not shown) on the second tape 20, and the first tape 19 is attached and fixed on the second tape 20 to close the openings of the chambers, so as to achieve the purpose of packaging the electronic components; wherein the first belt 19 is disposed on the third winding wheel 116 in a winding manner and used as a first supply end to sequentially pass through the stopping portion 18, the applying unit 12, the drying portion 13, the stretching portion 18 and the combining unit 14, and then wound up by using the first winding wheel 112 as a collecting end; the second tape 20 is also disposed on the second reel 113 in a tape-wound form, and is taken as a second supply end, sequentially passes through the electronic component placing and processing area 114 and the combining unit 14, and is also taken up by taking the first reel 112 as a collection end.

By the above components, the parallel mechanism 10 for packaging the electronic components and applying the adhesive on the carrier tape drives the first reel 112 to perform the intermittent rotation movement by the transmission of the second power portion 16 through the belt 161, so that the first tape 19 and the second tape 20 which are wound up intermittently pass through the combining unit 14 by a second movement while synchronously passing through the combining unit 14, and perform the intermittent displacement, so as to easily place the electronic components into the vacant compartment when the second tape 20 passes through the electronic component placing and processing area 114, and then seal the first tape 19 on the second tape 20 in the combining unit 14 by a known combining procedure.

The adhesive used for bonding the first tape 19 and the second tape 20 is applied to the bonding surface 191 on one side of the tape body of the first tape 19 by the application unit 12 through a known application procedure, specifically, when the first tape 19 passes through the application unit 12, between the positioning block 124 and the application ends 123, and the bonding surface 191 slides against the nozzle of the application ends 123, so that the adhesive stored in the container 122 can be applied to the bonding surface 191 continuously passing through the application ends 123, after application, the adhesive passes through the drying part 13 and is dried to a degree that sufficient adhesive flow is avoided, but still can be changed according to different requirements, for example, the adhesive passes through the drying part 13 at a fixed speed, or the adhesive stays in the drying part 13 is increased, and the like, and then the first tape 19 is attached to the roller 171 through the supporting surface 192 on the other side opposite to the bonding surface 191, the bonding surface 191 which is originally upward is turned downward so that the bonding surface 191 faces the second tape 20 in the bonding unit 14, so that the adhesive can adhere the first tape 19 and the second tape 20.

However, the displacement of the second power portion 16 driving the first belt 19 is intermittent motion, so that the adhesive is not matched with the application unit 12 in the application state of continuously flowing out the adhesive, therefore, the first power portion 15 intervenes therebetween, and as shown in fig. 6 and 7, the first belt 19 continuously passes through the application unit 12 at a first motion faster than the second motion by the power of continuously extending at the stable speed of the output shaft 151 when the application unit 12 applies the adhesive, thereby avoiding uneven adhesive application caused by the pause of the second power portion 16 during continuous adhesive output.

While the output shaft 151 is extending, the rollers 171 synchronously move and continuously roll on the supporting surface 192 of the first belt 19, so as to transmit the force of the first power portion 15 to drive the first belt 19 to perform the first motion, and to provide a supporting and expanding portion of the first belt 19 between the applying unit 12 and the combining unit 14, so that the combining surface 191 is maintained in an expanded state, and the mutual adhesion caused by folding is avoided.

However, because the stroke of the output shaft 151 of the first power portion 15 is limited, when the extending stroke of the output shaft 151 is exhausted, as shown in fig. 8 and 9, the first belt 19 is clamped by the stopping portion 18, so that the first belt 19 can not be taken out by the third winding wheel 116 any more, so as to interrupt the first movement, and simultaneously temporarily stop the output of the adhesive of the applying unit 12, so as to avoid applying excessive adhesive, at the same time, in order to ensure that the stopping force applied to the first belt 19 is enough to fix the relative position between the first belt 19 and the applying unit 12, and not slide by the continuous pulling of the second power portion 16, as shown in fig. 10 to 12, the stopping portion 18 further comprises a rotating body 185 pivoted on a carrier 186 protruding from the side of the upright column 115, and driven by external power to rotate on the carrier 186, a long plate-shaped pressing body 187 is fixed at one end to the rotating body 185, and the inclined plane at the other end is opposite to the wheel surface of the pressing wheel 125, so that when the rotating body 185 is rotated in the direction of fig. 11 by external power, the inclined plane at the other end of the pressing body 187 presses the pressing wheel 125, so that the pressing wheel 125 is tightly pressed on the part of the first belt 19 between the pressing wheel 125 and the positioning block 124, and the first belt 19 is braked together with the movable side 183, so as to ensure that the relative position between the first belt 19 and the application ends 123 is not changed. The external power for driving the rotator 185 to rotate may be, for example, a fluid pressure cylinder disposed on the carrier 186, and the rotator 185 is driven to rotate by a known transmission mechanism, but the driving technology of the external power is not shown in the figures.

Thereafter, the standby segment is continuously retracted into the first reel 112 by the operation of the second power portion 16, so that the length of the standby segment 193 is gradually shortened, and the output shaft 151 is passively and gradually retracted synchronously, and the roller 171 provides an expanding support for the standby segment 193, thereby preventing the bonding surfaces 191 from sticking to each other due to folding.

Then, when the retraction stroke of the output shaft 151 is exhausted, the extending stroke of the output shaft 151 is restarted, the first tape 19 clamped by the stopper 18 is released, the adhesive output of the application unit 12 is restarted, and the first movement of the first tape 19 is performed again to perform the next stroke of adhesive application.

Therefore, the parallel mechanism 10 for packaging and applying the adhesive on the carrier tape of the electronic component can prevent the adhesive from being affected by intermittent motion, and can maintain stable application at a constant speed in the extending stroke of the output shaft of the first power part 15, and at the same time, the first motion time based on the extending stroke of the output shaft 151 of the first power part 15 is longer than the motion time of the second motion, and the interruption time based on the retracting stroke of the stopper 18 and the output shaft 151 of the first power part 15 is also longer than the interruption time of the second motion, so that the application unit 12 can be prevented from repeatedly starting and stopping in a short time, and is easy to control, and compared with the prior art, the invention has remarkable efficacy improvement.
