Description

  The present invention relates to a pressure-sensitive adhesive tape sticking apparatus that cuts the pressure-sensitive adhesive tape into a predetermined length and sticks it to the electronic component when mounting the electronic component on a substrate such as a liquid crystal display panel.

  When mounting a TCP (Tape Carrier Package) as an electronic component on the side of the substrate, mounting is performed using an adhesive tape (ACF) made of an anisotropic conductive member. In that case, the adhesive tape is attached in advance to the side portion of the substrate, and a plurality of TCPs are mounted on the side portion at a predetermined interval.

  However, if a plurality of TCPs are stuck at a predetermined interval after sticking the adhesive tape to the side of the substrate, the portion of the adhesive tape located between adjacent TCPs may be wasted.

  Therefore, the adhesive tape is cut into a length that is substantially the same as the width dimension of the TCP, and the adhesive tape is attached to the TCP. A plurality of TCPs are mounted on a side portion of the substrate at a predetermined interval so as not to waste the adhesive tape.

  A sticking apparatus for sticking an adhesive tape cut to a predetermined length on a TCP has a supply reel as a supply unit. A release tape having the adhesive tape attached thereto is wound around the supply reel. The release tape to which the adhesive tape is attached is pulled out from the supply reel, guided by a guide roller, and intermittently run by a predetermined length by a transport mechanism including a chuck.

  The adhesive tape that is intermittently pulled out by a predetermined length together with the release tape from the supply reel is cut into a length corresponding to the width of the TCP by a cutting mechanism. A sticking means is provided in the conveyance path of the release tape, and the TCP is positioned at a sticking position, which is a position corresponding to the sticking means, and stands by.

  When the pressure-sensitive adhesive tape cut to a length corresponding to the width dimension of TCP is conveyed to the attachment position of the TCP, the pressure-sensitive adhesive tape is pushed up while being heated by a pressure tool via a release tape. And attached to the TCP.

  When the adhesive tape is attached to the TCP, the release tape is peeled from the adhesive tape. After peeling, the release tape is run by a predetermined length by the feeding mechanism, so that the adhesive tape cut to the predetermined length by the cutting mechanism is sequentially positioned at the adhesive position, and the adhesive tape is attached to the TCP. It is done repeatedly.

  As the feeding mechanism that travels by intermittently feeding the adhesive tape by a predetermined length, the above-described pair of chucks arranged on the downstream side in the traveling direction of the release tape from the adhesive position is used. The pair of chucks are separated at a predetermined interval, and one chuck provided on the downstream side in the conveyance direction of the release tape is driven to reciprocate.

  Then, the release tape is clamped by the pair of clamping pieces of one chuck, and the one chuck is driven in the running direction of the release tape with the pair of clamping pieces of the other transport chuck opening the release tape. This causes the release tape to run for a predetermined length.

  Then, if the release tape is clamped by the clamping piece of the other chuck, the clamping tape is released by the clamping piece of one chuck and the one chuck returns to the original position. By repeating, the release tape is intermittently run by a predetermined length.

JP 2010-080874 A

  By the way, when the adhesive tape attached to the release tape is cut to a predetermined length and attached to TCP, an extraction part is provided between the adhesive tapes to be cut to a predetermined length, and the extraction part is removed. An interval is formed between the adhesive tapes cut to a predetermined length. Thereby, only the adhesive tape cut to a predetermined length is surely pressed against the TCP so that it can be attached.

  However, if the adhesive tape is cut to a predetermined length and the extraction part between the adhesive tapes cut to the predetermined length is removed, a part of the adhesive tape remains on the release tape when the extraction part is formed. In this state, the release tape may be sent to the feeding mechanism.

  The release tape with the adhesive tape remaining is sent to the feed mechanism, and when the release tape is run by repeatedly holding and releasing the release tape by the holding surfaces of the pair of chucks of the feed mechanism, the residual adhesive tape The release tape sticks to and entangles with the holding surface of the holding piece of the chuck, and the release tape cannot be reliably run.

  Also, when a new supply reel is replaced, or when the operation of the mounting device is restarted, the adhesive tape that has been cut to a predetermined length is not attached to the TCP at the attachment position, and the release tape is placed at the chuck. May be sent to. Even in such a case, the adhesive tape remaining on the release tape may be entangled with the holding surface of the holding piece of the chuck, and the release tape may not be conveyed.

  The present invention prevents the release tape from sticking to the holding piece of the chuck of the feed mechanism even if the release tape with the adhesive tape remaining is fed to the chuck of the feed mechanism. It is in providing the sticking apparatus and sticking method of the adhesive tape which were made.

This invention is an adhesive tape attaching apparatus for attaching an adhesive tape attached to a release tape and cut to a predetermined length to an electronic component,
The release tape supply section;
A holding chuck having a pair of holding pieces to be opened and closed and a feeding chuck are provided, and the release tape is intermittently provided from the supply unit by a predetermined length by opening and closing the pair of holding pieces of the chuck and driving the feeding chuck. A feed mechanism that is pulled out to travel,
A cutting mechanism for cutting the adhesive tape attached to the release tape that is drawn out and travels by the feed mechanism into the predetermined length;
It comprises an adhering means for adhering the pressure-sensitive adhesive tape of the predetermined length that has been cut by the cutting mechanism and positioned at the adhering position to the electronic component that waits at the adhering position by being heated under pressure,
Among clamping face of the clamping piece of the respective chuck, characterized in that the clamping face opposing at least the release tape of the adhesive tape has been adhered surface has been wetted by the non-adhesive with fluidity It is in the adhesive tape sticking device.

  According to this invention, among the pair of holding pieces of the chuck constituting the feeding mechanism, the oil groove to be wetted with oil or fat is provided on the holding surface of the holding piece facing the surface on which the adhesive tape of the release tape is attached. Since the oil retaining layer for supplying oil to the oil groove is formed on the sandwiching piece, the sandwiching surface of the sandwiching piece flows from the oil reservoir to the oil groove and is wetted by the oil and fat diffusing from the oil groove. Can do.

  Therefore, even if the release tape on which the adhesive tape remains is clamped by the holding surface of the holding chuck of the feed mechanism and the clamping piece of the feed chuck, the adhesive tape remaining on the release tape is adhered to the clamping surface wetted by the oil and fat. Therefore, the release tape can be smoothly pitch-fed by each chuck of the feed mechanism.

  According to the present invention, at least a clamping surface of the pair of clamping pieces of the chuck of the feeding mechanism facing the surface on which the adhesive tape of the release tape is attached is covered with a non-adhesive coating material.

  Therefore, even if the release tape to which the adhesive tape is attached is held by the holding surface of the holding chuck of the feed mechanism and the holding piece of the feed chuck, it remains on the release tape on the holding surface covered with the non-adhesive coating material. Since the adhesive tape is prevented from sticking, the release tape can be smoothly pitch-fed by each chuck of the feeding mechanism.

Embodiments of the present invention will be described below with reference to the drawings.
1 to 6 show a first embodiment of the present invention, and the adhesive tape attaching apparatus shown in FIG. 1 includes a supply reel 11 as a supply unit. As shown in FIG. 2, a release tape 13 having an adhesive tape 12 attached to one side surface is wound around the supply reel 11. The adhesive tape 12 is an anisotropic conductive member in which metal fine particles are mixed in a thermosetting resin having adhesiveness on both sides, and the release tape 13 is formed into a tape shape having the same shape as the adhesive tape 12 by a synthetic resin. Has been.

  The release tape 13 is drawn downward together with the adhesive tape 12 from the supply reel 11 and is turned upward so that it is engaged with the dancer roller 15 having the weight 14 and given tension.

  And it engages with a pair of guide rollers 16a and 16b spaced apart at a predetermined interval in the horizontal direction, and runs horizontally with the surface to which the adhesive tape 12 is attached facing upward. The dancer roller 15 is provided to be movable in the vertical direction along a guide (not shown).

  In the release tape 13, the traveling direction is converted downward by a guide roller 16b on the downstream side in the transport direction from a state where the release tape 13 travels horizontally. , 18a are sequentially passed through and are collected in the collection tank 19. The holding chuck 17 and the feed chuck 18 constitute a feed mechanism 20.

  The pair of holding pieces 17a of the holding chuck 17 is driven to open and close by a first opening / closing drive source 22 such as a cylinder, and the pair of holding pieces 18a of the feed chuck 18 is driven to open and close by a second opening / closing drive source 23 such as a cylinder. At the same time, a vertical driving source 24 such as a cylinder is integrally driven with the second opening / closing driving source 23 in a vertical direction with a predetermined stroke.

  The first opening / closing drive source 22, the second opening / closing drive source 23, and the up / down drive source 24 are controlled by a control device 25 shown in FIG. That is, when the pair of holding pieces 17a of the holding chuck 17 is opened, the pair of holding pieces 18a of the feed chuck 18 is closed by the second opening / closing drive source 23, and the release tape 13 is held in that state. The feed chuck 18 is driven downward by a vertical drive source 24 with a predetermined stroke as indicated by an arrow in FIG.

  Thereby, the release tape 13 is fed by the feed chuck 18 at a predetermined length corresponding to the stroke against the tension applied by the dancer roller 15. The feed direction of the release tape 13, that is, the traveling direction is indicated by an arrow X in FIG.

  When the release tape 13 is fed by the feed chuck 18, the pair of holding pieces 17a of the holding chuck 17 is closed by the first opening / closing drive source 22, and the holding surfaces 17b formed on the side surfaces of the holding pieces 17a. The release tape 13 is held.

  Next, after the pair of clamping pieces 18a of the feed chuck 18 are opened and driven to the raised position, the release tape 13 is clamped by the clamping surfaces 18b that are driven in the closing direction and formed on the side surfaces of the clamping pieces 18a. .

  At the same time, the holding chuck 17 is opened, and the feed chuck 18 is driven in the downward direction indicated by the arrow in FIG. 1 by the vertical drive source 24 to feed the release tape 13 by a predetermined length.

  As shown in FIGS. 4 and 5, one of the pair of holding pieces 17a and 18a of the holding chuck 17 and the feed chuck 18 facing the surface of the release tape 13 to which the adhesive tape 12 is attached. The sandwiching surfaces 17b and 18b of the sandwiching pieces 17a and 18a are formed on a rough surface r as shown in FIG. 6 by, for example, performing shot peening. The rough surface r is formed on the entire holding surfaces 17b and 18b. However, the rough surface r may be formed only on a portion of the 17b and 18b that holds the release tape 13.

  Further, a pair of oil grooves 5 as flow grooves spaced apart at a predetermined interval in the up and down direction are provided on the holding surfaces 17 b and 18 b of one of the holding pieces 17 a and 18 a of each chuck 17 and 18 along the front-rear direction intersecting the up and down direction. Is formed. An oil reservoir 6 is formed as a concave non-adhesive reservoir in which the rear ends of the oil grooves 5 communicate with each other at the rear end portion of the clamping surfaces 17b and 18b that are separated from the portion that holds the release tape 13. Each oil sump 6 has a high viscosity and is filled with grease as a non-adhesive agent having fluidity such as non-adhesive oils such as silicon. It is preferable that the grease is filled not only in the oil reservoir 6 but also in the oil groove 5 before starting the sticking device.

  The grease filled in each oil reservoir 6 gradually flows into the oil groove 5 and diffuses from the oil groove 5 to the clamping surfaces 17b and 18b formed on the rough surface r of each clamping piece 17a and 18a. That is, since the rough surface r has concave portions that are continuous with a large number of convex portions, the grease that has flowed into the oil groove 5 flows into the concave portions of the rough surface r and diffuses throughout the rough surface r.

  Therefore, even if the adhesive tape 12 remains on one surface of the release tape 13 held by the holding surfaces 17b, 18b of the holding pieces 17a, 18a of the holding chuck 17 and the feed chuck 18, the adhesive tape 12 This prevents one surface of the release tape 13 from sticking to the clamping surfaces 17b and 18b of the clamping pieces 17a and 18a.

  In this embodiment, the rough surface r, the oil groove 5 and the oil sump 6 constitute sticking prevention means.

  In addition, although the holding surfaces 17b and 18b of the holding pieces 17a and 18a of the holding chuck 17 and the feed chuck 18 are formed on the rough surface r, oil and fat are diffused to the holding surfaces 17b and 18b. The pieces 17a and 18a may be formed of a porous material such as a sintered oil-impregnated metal or an oilless metal (oil oil-impregnated metal).

  By doing so, the sandwiching surfaces 17b and 18b become rough surfaces having concave and convex portions due to the oil-containing porous material, so that the oil impregnated in the porous material oozes out and a lubricating oil film can be formed. .

  When each sandwiching piece 17a, 18a is formed of a porous material such as sintered oil-impregnated metal or oilless metal, the oil groove 5 is provided on the sandwiching surfaces 17b, 18b, or the oil sump 6 is provided on the sandwiching pieces 17a, 18a. Even if not provided, it is possible to prevent the release tape 13 from adhering to the above-described 17b and 18b.

  Of the pair of holding pieces 17a and 18a of the holding chuck 17 and the feed chuck 18, only the holding surfaces 17b and 18b facing the surface to which the adhesive tape 12 of the release tape 13 is attached are provided in the oil groove 5. However, the sandwiching surfaces 17b and 18b of the pair of sandwiching pieces 17a and 18a may be formed on the rough surface r having the oil groove 5 and the oil reservoir 6.

  When the oil groove 5 is provided only on one of the sandwiching surfaces 17b and 18b of the sandwiching pieces 17a and 18a, the surface of the release tape 13 to which the adhesive tape 12 is attached is prevented from sticking.

  Moreover, when the oil groove 5 is provided in both the clamping surfaces 17b and 18b of each clamping piece 17a and 18a, the surface where the adhesive tape 12 of the release tape 13 was affixed, and the surface where the adhesive tape 12 is not affixed And both are prevented from sticking.

  In the portion where the release tape 13 is vertically changed by the dancer roller 15, a belt-like support is provided on the other side opposite to the side where the adhesive tape 12 of the release tape 13 is attached. A member 27 is provided. The release tape 13 travels along the plate surface of the support member 27.

  As shown in FIG. 2, a pair of cutting lines 28a are formed on the pressure-sensitive adhesive tape 12 attached to the release tape 13, as shown in FIG. A cutting mechanism 31 for forming the extraction part 28b in the adhesive tape 12 is provided.

  The cutting mechanism 31 includes a cutting cylinder 32 as a drive source arranged with its axis orthogonal to the side surface of the release tape 13 and a pedestal 33 connected to a rod 32a of the cutting cylinder 32. It is constituted by a pair of cutting blades 34 provided at a predetermined interval.

  When the cutting blade 34 is driven by the cutting cylinder 32 toward the adhesive tape 12 affixed to the release tape 13 as indicated by the arrow S in FIG. 2, the pair of cutting blades 34 are attached to the adhesive tape 12. A pair of cutting lines 28a is formed. That is, the extraction part 28 b is formed in the adhesive tape 12.

  When the extraction portion 28b is formed in the adhesive tape 12, the release tape 13 is intermittently conveyed at a pitch P (shown in FIG. 2) corresponding to the stroke of the feed chuck 18 of the feed mechanism 20. As a result, the extraction part 28 b formed on the adhesive tape 12 by the cutting mechanism 31 is positioned opposite to the extraction mechanism 36.

  The extraction mechanism 36 has an extraction cylinder 37 as a drive source, and a pedestal 38 is provided on a rod 37 a of the extraction cylinder 37. The pedestal 38 is provided with a pressing portion 38a, and a sticking tape 39 that runs from a supply reel and is wound around a take-up reel (both not shown) is stretched on the front end surface of the pressing portion 38a. Has been.

  When the extraction cylinder 37 is operated and the adhesive tape 39 is pressed by the pressing portion 38 a against the extraction portion 28 b formed on the adhesive tape 12, the extraction portion 28 b is attached to the adhesive tape 39. Has been removed.

  As shown in FIG. 3, the operation of the cutting cylinder 32 and the extraction cylinder 37, that is, the supply and discharge of compressed air to the cylinders 32 and 37 via control valves (not shown) are performed by the control device 25. Is called.

  In this way, if the extracted portions 28b formed on the adhesive tape 12 at the predetermined pitch P by the cutting mechanism 31 are adhered and removed by the adhesive tape 39 of the extraction mechanism 36, the adhesive tape 12 has a predetermined length. The cut portion 12a is divided. This cutting part 12a is set to have substantially the same length as the width dimension of the TCP 42 as an electronic component described later.

  The stroke of the feed chuck 18 driven by the vertical drive source 24 can be changed. Thereby, the length of the cutting part 12a of the adhesive tape 12 cut by the cutting mechanism 31 can be set according to the size change of the TCP 42 or the like.

  After the adhesive tape 12 is cut into the predetermined length of the cutting portion 12a, when the pitch feeding of the release tape 13 by the feeding mechanism 20 is repeated a plurality of times, the cutting portion 12a waits with the TCP 42 positioned. It is conveyed to the sticking position B (shown in FIG. 1).

  At the sticking position B, a rotary table 44 is provided above the cutting portion 12a of the adhesive tape 12 conveyed to the sticking position B. The rotary table 44 is provided with a plurality of holding portions 45 at a predetermined angle in the circumferential direction.

  Each holding portion 45 holds the upper surface of one end in a direction intersecting the width direction of the TCP 42 by suction, and a cut portion 12a of the adhesive tape 12 is adhered to the lower surface of the one end. The TCP 42 sucked and held by the holding portion 45 is positioned slightly above the cutting portion 12a of the adhesive tape 12 that has been transported and positioned to the sticking position B.

  The rotary table 44 is rotationally driven by a predetermined angle by a rotational drive source 46 controlled by the control device 25 as shown in FIG. Accordingly, the holding part 45 holding the TCP 42 by suction is sequentially positioned above the sticking position B.

  As shown in FIG. 1, a sticking means 47 is provided below the release tape 13 at a position facing the rotary table 44. The sticking means 47 has a pressing tool 48 having a planar shape slightly larger than the cutting portion 12a. The pressurizing tool 48 is driven in the vertical direction by a vertical cylinder 49 whose drive is controlled by the control device 25.

  The pressure tool 48 has a built-in heater 50, which is heated to a predetermined temperature, that is, a temperature at which the adhesive tape 12 can be reliably attached to the TCP 42. Although not shown in detail, energization of the heater 50 is also controlled by the control device 25.

  When the up / down cylinder 49 is actuated and the pressurizing tool 48 is driven in the upward direction, the cut portion 12a of the adhesive tape 12 positioned at the adhering position B is adhered to the adhering via the release tape 13. It is stuck to the TCP 42 held by the holding part 45 positioned at the position B.

  When the cut portion 12a is attached to the TCP 42, the release tape 13 is peeled from the cut portion 12a by a release roller (not shown). Next, the rotary table 44 is rotated by a predetermined angle, and a new TCP 42 is positioned at the sticking position B. The TCP 42 to which the cutting part 12a of the adhesive tape 12 is attached is transferred from the holding part 45 to a mounting tool and mounted on a substrate (both not shown) such as a liquid crystal display panel.

  According to the sticking apparatus having the above-described configuration, the release tape 13 is intermittently pulled out from the supply reel 11 by a predetermined length by the feed mechanism 20, and the adhesive tape 12 is stuck by the pair of guide rollers 16a and 16b. The vehicle is guided horizontally with the surface facing up.

  The adhesive tape 12 adhered to the release tape 13 is cut and formed by the pair of cutting blades 34 of the cutting mechanism 31 before reaching the upstream guide roller 16a. Each time the release tape 13 is conveyed by the feed chuck 18 of the feed mechanism 20 with a predetermined stroke, the extraction portion 28 b is removed by the sticking tape 39 of the extraction mechanism 36. As a result, the adhesive tape 12 adhered to the release tape 13 is divided into cut portions 12a having a predetermined length.

  Thus, when the cut part 12a of the divided adhesive tape 12 reaches the sticking position B, the pressurizing tool 48 of the sticking means 47 is driven in the upward direction by the vertical cylinder 49. As a result, the cutting part 12a of the adhesive tape 12 is pressed while being heated on the lower surface of the TCP 42 which is held and positioned by the holding part 45 of the rotary table 44 at the sticking position B. Affixed to.

  Even if the cut portion 12 a of the adhesive tape 12 is stuck to the TCP 42 at the sticking position B, the adhesive tape 12 is cut and formed on the upper surface of the release tape 13 by the pair of cutting blades 34 of the cutting mechanism 31. Some of them may remain as residues.

  Then, the pitch feed of the release tape 13 is repeatedly performed by the feed mechanism 20 so that the release tape 13 with the adhesive tape 12 remaining reaches the location of the holding chuck 17 and the feed chuck 18 of the feed mechanism 20. become.

  When the release tape 13 with the adhesive tape 12 remaining was sandwiched by the sandwiching surfaces 17b and 18b of the pair of sandwiching pieces 17a and 18a of the chucks 17 and 18, the adhesive tape 12 of the release tape 13 was stuck. In some cases, the release tape 13 is stuck and entangled with each of the holding surfaces 17b and 18b facing each other, and the release tape 13 cannot be pitched.

  However, among the pair of sandwiching pieces 17a and 18a of the chucks 17 and 18, the sandwiching surfaces 17b and 18b facing the surface to which the adhesive tape 12 of the release tape 13 is attached are shown in FIGS. In this way, the rough surface r is formed with an oil groove 5 communicating with an oil sump 6 filled with grease, which is an oil and fat as a non-adhesive agent. The grease in the oil reservoir 6 flows into the oil groove 5 and diffuses from the oil groove 5 to the rough surface r.

  Therefore, in order to pitch-feed the release tape 13 in which the adhesive tape 12 remains, even if the clamping and release by the clamping surfaces 17b and 18b of the pair of clamping pieces 17a and 18a of the chucks 17 and 18 are repeated, It is prevented that the surface of the release tape 13 where the adhesive tape 12 remains adheres to the sandwiching surfaces 17b and 18b and becomes entangled, and the pitch feed of the release tape 13 cannot be smoothly performed.

  Further, the adhesive tape 12 divided into a predetermined length of the cutting part 12a by the cutting mechanism 31 is not attached to the TCP 42 due to interruption of the attaching operation or the like, and remains on the release tape 13 to be sent to the feeding mechanism 20. Even if the release tape 13 in which the cut portion 12a of the adhesive tape 12 remains is sent to the feeding mechanism 20 when cueing the release tape 13 when the sticking device is started up, the release tape 13 is released. It is possible to prevent the mold tape 13 from sticking to the sandwiching surfaces 17b and 18b of the sandwiching pieces 17a and 18a.

  FIG. 7 shows a second embodiment of the present invention. In the first embodiment, the oil groove 5 serving as the flow groove constituting the sticking prevention means has at least the adhesive tape 12 of the release tape 13 among the pair of sandwiching pieces 17a and 18a of the chucks 17 and 18. Although formed on the sandwiching surfaces 17b and 18b of the one sandwiching piece 17a and 18a opposite to the pasted surface, in this second embodiment, an oil reservoir as a non-adhesive reservoir that constitutes the sticking prevention means 6A is formed on the upper surface of the clamping pieces 17a and 18a adjacent to the clamping surfaces 17b and 18b.

The oil reservoir 6A is filled with a non-adhesive oil such as a silicon-based non-adhesive material having a viscosity lower than that of grease as a non-adhesive agent and flowing at room temperature. That is, in order to fill the oil reservoir 6A with low-viscosity oil, the oil reservoir 6 is formed on the upper surfaces of the sandwiching pieces 17a and 18a so that the oil filled in the oil reservoir 6A flows into the oil groove 5 without dripping. I am doing so.
The bottom of the oil sump 6 </ b> A and the rear end of the oil groove 5 communicate with each other through a communication path 51.

  Even in such a configuration, the oil can be diffused to the clamping surfaces 17b and 18b formed on the rough surface r of the clamping pieces 17a and 18a, so that the release tape 13 on which the adhesive tape 12 remains is It is possible to prevent tangling by sticking to the surfaces 17b and 18b.

  FIG. 8 shows a third embodiment of the present invention. Note that the same parts as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the third embodiment, of the pair of holding pieces 17a and 18a of the chucks 17 and 18, at least one holding piece 17a and 18a facing the surface to which the adhesive tape 12 of the release tape 13 is attached. In addition, for example, a tube-shaped covering material 66 such as a non-adhesive resin such as a silicon-based material is attached, and the covering material 66 is thermally contracted, so that At least a portion sandwiching the release tape 13 was covered with a covering material 66, and an adhesion preventing means for preventing the release tape 13 with the adhesive tape 12 remaining from being adhered was used.

  The sandwiching pieces 17a and 18a are entirely covered with the tube-shaped covering material 66. However, the sandwiching pieces 17a can be applied by applying a non-adhesive resin such as silicon to the sandwiching surfaces 17b and 18b. , 18a, at least the clamping surfaces 17b, 18b may be covered. Alternatively, the sandwiching surfaces 17b and 18b of the pair of sandwiching pieces 17a and 18a may be covered with a covering material 66 to serve as sticking prevention means.

  According to such a configuration, even if the adhesive tape 12 is stuck to the release tape 13 sent to the feeding mechanism 20, the sandwiching surfaces 17b and 18b are covered by the covering material 66 that covers the sandwiching surfaces 17b and 18b. Therefore, it is possible to prevent the release tape 13 from being entangled with the sandwiching pieces 17a and 18a and being unable to smoothly feed the pitch.

  In each of the above-described embodiments, the case where the adhesive tape cut to a predetermined length is mounted on the TCP has been described as an example. However, this is the case where the adhesive tape is attached to the substrate on which the TCP is mounted. However, the present invention can be applied. That is, the electronic component is not limited to TCP, and may be a substrate on which TCP is mounted.
