Specifically, as described above, when the first transfer unit 210 and the second transfer unit 220 operate, the rotating unit 230 may rotate passively. However, it can actively rotate according to the result measured by the first sensor unit 400.

For example, as described above, when it is determined that the first carrier tape 3 is exhausted from the first detection sensor unit 400, the rotation unit 230 rotates to rotate the second carrier tape 1 to the first transfer unit. It may be transferred to the 210 and the second transfer unit 220 side. At this time, the third driving unit generates a driving force, and the rotating unit 230 may rotate by the driving force.

In addition, the movement preventing unit 124 may be formed on the front side of one end of the second carrier tape 1 centering on the transfer direction of the first carrier tape 3. Therefore, when the first carrier tape 3 is transferred, the movement preventing unit 124 supports the end of the second carrier tape 1 to prevent the second carrier tape 1 from being transferred.

Meanwhile, the carrier tape loading unit 100 may include a block unit 130 rotatably installed on the base frame 600. At this time, the rotation center of the block unit 130 may coincide with the rotation center of the rotation unit 230. In addition, the block unit 130 may force the second carrier tape 1 toward the rotation unit 230 according to the rotation of the handle unit 120.

Specifically, one end of the block 130 may be inclined. At this time, the inclined portion of the block portion 130 may be formed to contact the upper surface of the second carrier tape (1). Particularly, since the longitudinal direction from the center of rotation of the block portion 130 forms a certain angle with the outer surface of the second carrier tape 1, a part of the bottom surface of the block portion 130 forms an inclination to form the slope of the second carrier tape 1. It can make surface contact with the upper surface.

In addition, the first elastic portion 150 may include a torsion spring installed at the rotation center of the handle portion 120 and the block portion 130. The first elastic part 150 may include a compression spring in addition to the above. Hereinafter, for convenience of description, the first elastic portion 150 will be described in detail mainly in the case of including a compression spring.

At this time, a first insertion groove (not shown) may be formed in the handle portion 120 and the block portion 130 so that both ends of the first elastic portion 150 are respectively inserted. Therefore, the first elastic part 150 can accurately apply a force to the handle part 120 and the block part 130.

Meanwhile, the carrier tape loading unit 100 may include a detachment preventing member 160 installed between the handle unit 120 and the block unit 130 to prevent detachment of the first elastic unit 150. At this time, the departure preventing member 160 may be installed to penetrate the first elastic portion 150, it may be installed to be inserted into one of the handle portion 120 or the block portion 130. Particularly, when the handle part 120 or the block part 130 rotates, the departure preventing member 160 may maintain a difference in rotation angle between the handle part 120 and the block part 130 within a predetermined range.

The carrier tape loading unit 100 may include a connecting member 170 connecting the handle unit 120 and the base frame 600. At this time, the connecting member 170 may be installed to be spaced a predetermined distance from the center of rotation of the handle unit 120.

The second elastic part 180 may be installed at a portion where the connecting member 170 is installed. Specifically, the second elastic portion 180 may be installed between the handle portion 120 and the base frame 600 so that the connecting member 170 is inserted therein. At this time, a second insertion groove (not shown) may be formed in the handle portion 120 and the base frame 600 such that both ends of the second elastic portion 180 are partially inserted and seated, respectively.

Meanwhile, hereinafter, the operation of the carrier tape loading unit 100 will be described in detail.

5 is a conceptual view showing a first operation of the carrier tape loading unit 100 shown in FIG. 4. 6 is a conceptual view showing a second operation of the carrier tape loading unit 100 shown in FIG. 4.

5 and 6, briefly explaining the operation of the transfer module and the carrier tape loading unit 100, the transfer module transfers the first carrier tape 3 toward the cover tape removal unit 700. Can be formed.

In addition, the carrier tape loading unit 100 is functionally connected to the transfer module to transfer the second carrier tape 1 subsequently input when the connection between the first carrier tape 3 and the transfer module is released. It can be connected to a module.

In particular, the carrier tape loading unit 100 may limit the transfer of the second carrier tape 1 to the cover tape removal unit 700 while the first carrier tape 3 and the transfer module are connected.

Specifically, the cover tape removal unit 700 of the second carrier tape 1 in a manner that the end of the carrier tape loading unit 100 is inserted into a second transport hole formed at regular intervals on the side of the second carrier tape 1 The transfer to the furnace can be restricted.

In addition, the carrier tape loading unit 100 may connect the second transport hole of the second carrier tape 1 to the transport module when the connection between the first carrier tape 3 and the transport module is released. Specifically, the second transport hole of the second carrier tape 1 may be connected to the transport module in such a way that the end of the carrier tape loading unit 100 is pulled out of the second transport hole.

In order to drive the carrier tape supply device F, the user can install a first winding roll (not shown) on which the first carrier tape 3 is wound, outside the carrier tape supply device F. Also, a second winding roll (not shown) on which the second carrier tape 1 is wound can be installed outside the carrier tape supply device F.

At this time, the first carrier tape 3 may be withdrawn from the first winding roll and installed in the carrier tape supply device F. Specifically, the first carrier tape 3 is introduced into the inside of the carrier tape supply device F through the single inlet formed in the base frame 600 to rotate the 230, the first sprocket 211, and the second sprocket ( It can be installed so as to be bound to the outer surface of 221).

At this time, the gear of the rotating part 230, the gear of the first sprocket 211 and the gear of the second sprocket 221 are respectively inserted into some of the first transport holes 3b formed in the first carrier tape 3 Can be.

On the other hand, when the above-described operation is completed, the second carrier tape 1 can be withdrawn from the second winding roll and inserted into the carrier tape supply device F. At this time, the second carrier tape 1 may be inserted inward along the outer surface of the first carrier tape 3. When the second carrier tape 1 is inserted as described above, the second carrier tape 1 can be stopped at a portion where the handle unit 120 is located.

When the second carrier tape 1 is inserted as described above, the user can rotate the handle unit 120. Specifically, when the gripping part 121 is gripped and applied, the handle body part 122 may be rotated together with the gripping part 121.

When the handle body portion 122 rotates, the handle body portion 122 may rotate in the first direction around the base frame 600. At this time, the located government 191 can rotate with the handle body portion 122.

The located government 191 can move inside the guide hole of the guide portion 195 to a certain degree while rotating. At this time, when the located government 191 reaches the end of the guide hole, the located government 191 may apply a force to the block 130. In this case, the block 130 may rotate in the first direction together with the handle body 122 by the located government 191.

On the other hand, when the handle body portion 122 and the block portion 130 are moved as described above, the second elastic portion 180 presses the handle body portion 122 in a second direction opposite to the first direction. can do. At this time, the second elastic portion 180 may be compressed by the motion of the handle body portion 122.

When the handle body portion 122 is rotated in the first direction through the gripping portion 121 as described above, a space may be formed between the block portion 130 and the first carrier tape 3. At this time, the end of the second carrier tape 1 may be disposed on one side of the block unit 130 through the space.

When the arrangement of the second carrier tape 1 is completed as described above, the handle unit 120 may be rotated in the second direction. At this time, as described above, the second elastic part 180 may assist the rotation of the handle part 120 by pressing the handle body part 122 in the second direction.

As described above, when the handle unit 120 rotates in the second direction, the block unit 130 may also rotate in the second direction. At this time, the first elastic portion 150 may apply a force to separate the block portion 130 and the handle body portion 122 from each other.

Meanwhile, when the handle unit 120 and the block unit 130 rotate as described above, the rotation angle of the handle unit 120 may be limited. Specifically, when the handle portion 120 rotates in the second direction, the handle body portion 122 may contact a portion of the connecting member 170.

At this time, the cross-sectional area of one end of the connecting member 170 may be formed differently from the cross-sectional area of other parts of the connecting member 170. For example, the cross-sectional area of one end of the connecting member 170 may be formed larger than the cross-sectional area of other parts of the connecting member 170.

Therefore, when the handle body portion 122 rotates in the second direction and reaches one end of the connecting member 170, the rotation angle may be limited because it no longer rotates. In particular, the connection member 170 restricts the rotation of the handle body portion 122, thereby preventing the second carrier tape 1 from being damaged by the handle portion 120 pressing the second carrier tape 1 excessively. have.

On the other hand, when the handle body portion 122 is rotated as described above, the insertion protrusion 123 may be inserted into the second transfer hole 1b formed in the second carrier tape 1. Therefore, the second carrier tape 1 may be bound to the handle portion 120 due to the insertion protrusion 123.

In addition, when the handle body portion 122 is rotated as described above, the block portion 130 may contact the outer surface of the second carrier tape 1. In particular, the inclined bottom surface of the block portion 130 may contact the upper surface of the second carrier tape 1.

At this time, the block unit 130 may rotate at a certain angle in the first direction while contacting the outer surface of the second carrier tape 1. Specifically, the block unit 130 may rotate in the first direction in proportion to the thickness of the second carrier tape 1.

In particular, when the block portion 130 rotates in the first direction as described above, the first elastic portion 150 may force the block portion 130 toward the rotation portion 230. At this time, the block portion 130 is completely in close contact with the second carrier tape 1, the second carrier tape 1 can be applied to the rotating portion 230 and the first carrier tape (3). In particular, the second carrier tape 1 may move in the transport direction of the first carrier tape 3 together with the first carrier tape 3 by an external force such as frictional force while the first carrier tape 3 is being transported. have.

In the above case, the insertion protrusion 123 can primarily prevent the second carrier tape 1 from being transferred to the first carrier tape 3. In addition, when the second carrier tape 1 deviates from the insertion protrusion 123, the movement preventing unit 124 can prevent the transfer of the second carrier tape 1.

Accordingly, in the case of the above operation, the second carrier tape 1 can stably and continuously maintain the current state while the first carrier tape 3 is continuously transferred to an external component mounting device (not shown).

Meanwhile, when the carrier tape loading unit 100 operates as described above, the first carrier tape 3 may be connected to the transfer module. Specifically, the first carrier tape 3 may be sequentially connected to the rotating part 230, the first conveying part 210, and the second conveying part 220.

In addition, the first carrier tape 3 may be transported while being connected to the transport module when the first transport unit 210 and the second transport unit 220 are driven. At this time, as described above, the end of the carrier tape loading unit 100 is inserted into the second transport hole of the second carrier tape 1 to the cover tape removal unit 700 of the second carrier tape 1. Transport can be restricted.

While operating as described above, the first carrier tape 3 wound on the first winding roll may be completely exhausted. In particular, when the first carrier tape 3 is completely exhausted, the first carrier tape 3 may be disconnected from the transfer module. At this time, the first detection sensor unit 400 may determine whether the first carrier tape 3 is exhausted.

Specifically, the first sensing sensor unit 400 may generate a signal to the outside when the first carrier tape 3 is completely exhausted. For example, when the first carrier tape 3 is present, the first detection sensor unit 400 may check the existence of the first carrier tape 3 because light is not measured by the optical sensor. On the other hand, when the first carrier tape 3 does not exist, the first detection sensor unit 400 may check the absence of the first carrier tape 3 since light is measured by the optical sensor.

As described above, if it is determined that the first carrier tape 3 is not present in the first detection sensor unit 400, the carrier tape loading unit 100 may supply the second carrier tape 1 to the transfer module.

At this time, when the second carrier tape 1 is supplied as described above, the transfer module and the second carrier tape 1 may be connected. In particular, the second carrier tape 1 may be connected to the rotating part 230. In particular, in such a case, the insertion protrusion 123 may be withdrawn from the second transport hole of the second carrier tape 1. At this time, the second conveying hole of the second carrier tape 1 may be connected to the rotating part 230 by inserting the gear of the rotating part 230.

When the connection of the second carrier tape 1 is completed as described above, the rotating unit 230 may be rotated. At this time, the carrier tape supply device F can control the rotating unit 230 by providing a control unit (not shown) for determining a signal and controlling rotation of the rotating unit 230.

Meanwhile, as described above, when the first carrier tape 3 is exhausted, the second carrier tape 1 may be supplied to the rotating part 230. Specifically, when the first carrier tape 3 is completely exhausted, the second carrier tape 1 and the first carrier tape 3 may not contact each other. At this time, the block portion 130, which receives the force from the first elastic portion 150 toward the rotating portion 230, may apply the second carrier tape 1 to the rotating portion 230.

The second carrier tape 1 may be supplied to the rotating part 230 side by the force. At this time, the block unit 130 may be limited in the path supplied by the located government 191 and the guide unit 195, that is, the rotation angle.

Specifically, when the second carrier tape 1 is in contact with the first carrier tape 3, the located government 191 may be located in the central portion of the guide portion 195. On the other hand, when the first carrier tape 3 and the second carrier tape 1 do not come into contact with each other, the located top portion 191 is one end of the guide portion 195 by the force applied from the first elastic portion 150 You may not be able to move any further by contacting.

Particularly, when the positioned positive projection (not indicated) is inserted into the guide hole, the positioned positive projection may stop by moving from the central portion of the guide hole to the end portion of the guide hole. The block portion 130 can be prevented from exerting excessive force on the second carrier tape 1 by mutually acting with the government 191 and the guide portion 195 positioned as described above.

Meanwhile, when the second carrier tape 1 is bound to the rotating part 230 as described above, the control part may rotate the rotating part 230. At this time, the first detection sensor unit 400 may detect the starting point of the second carrier tape 1. The method in which the first detection sensor unit 400 detects the starting point of the second carrier tape 1 is similar to that described above, so a detailed description thereof will be omitted.

Based on the value detected by the first detection sensor unit 400 as described above, the control unit is the time until the start point of the second carrier tape 1 arrives at the first transfer unit 210 and the second transfer unit 220 Or you can calculate the distance, etc.

The control unit may control at least one of the rotation speed, rotation time, and rotation angle of the rotation unit 230 based on the time or distance calculated above. When the rotating part 230 rotates as described above, the second carrier tape 1 may be transferred to the first conveying part 210 and the second conveying part 220.

On the other hand, according to the conventional carrier tape supply method, the operator waits until the time when the first carrier tape 3 being input is almost exhausted, and then the base end of the second carrier tape 1 to be continuously input and the first carrier tape 3 ) Had to be connected to each other using a dedicated connecting tape.

However, the carrier tape supply device F according to an embodiment of the present invention inserts the second carrier tape 1 to be subsequently input into the component mounting device at any time and presses the handle unit 120 in the second direction. If it is waited, it can be automatically supplied at the time when the supply of the first carrier tape 3 is completed, thereby reducing the amount of work and time required for supply of the carrier tape.

In addition, according to the conventional carrier tape supply method, precision is required in the process of connecting the base end of the second carrier tape 1 and the ends of the first carrier tape 3 to each other, so that when unskilled people work, it will be mounted at the connection site Loss of parts could occur.

However, the carrier tape supply device F according to an embodiment of the present invention does not require a separate carrier tape connection operation and can automatically supply a plurality of carrier tapes, thereby minimizing product loss due to unskilled work. have.

The carrier tape loading unit 100 'may supply the second carrier tape 1 as described above after the transfer of the first carrier tape 3 is completed. In addition, when the supply of the second carrier tape 1 is completed, the second carrier tape 1 may be transferred to the first transfer unit 210 and the second transfer unit 220 by the rotating unit 230.

On the other hand, if the transfer of the second carrier tape 1 is completed after the second carrier tape 1 is supplied, the first carrier tape 3 described above can operate similarly to the operation after the transfer is completed.

Specifically, when the transfer of the second carrier tape 1 is completed, the third carrier tape (not shown) may be supplied to the rotating portion 140 'side by the block portion 130'. In addition, the rotating part 140 'may rotate to transfer the third carrier tape to the first sprocket 211 and the second sprocket 221.

In particular, while the first carrier tape 3, the second carrier tape 1 and the third carrier tape 10 are sequentially transported, the block portion 130 'includes the second carrier tape 1 and the third carrier tape. By applying a force to the (10) it can be supplied to the rotating portion 140 'as described above.

Therefore, the carrier tape supply device F supplies the first carrier tape 3, the second carrier tape 1 and the third carrier tape 10 to the rotating part 230 through the block part 130 ′, and thereby the carrier tape. It is possible to sequentially supply the carrier tape to the component mounting apparatus without replacing.

In particular, the carrier tape supply device F allows the component mounting process to be performed quickly and smoothly by sequentially supplying carrier tapes as described above.

The tape support 710 may be coupled to the upper side of the base frame 600. The first sprocket 211 and the second sprocket 221 are installed on the base frame 600. The first sprocket 211 and the second sprocket 221 are disposed under the tape support portion 710 to contact the first carrier tape 3 and perform a function of moving the first carrier tape 3.

The tape support portion 710 includes long holes 711 and 712 at positions corresponding to the gear teeth 211a and 221a of the first sprocket 211 and the second sprocket 221. The long holes 711 and 712 also extend along the transport direction of the first carrier tape 3. The first sprocket 211 and the second sprocket 221 are straight lines extending along the transport direction of the first carrier tape 3 at positions corresponding to the first transport holes 3b of the first carrier tape 3 ( L2).

The tape support portion 710 includes a hole 713 for picking up a part that exposes the area where the first cover tape 2 is separated from the first carrier tape 3 to the outside.

The separating part 720 is disposed to cross a straight line L1 extending along the transport direction of the first carrier tape 3 at the contact point P1 of the first sprocket 211 and the first carrier tape 3. .

The inclination angle θ2 of the first inclined surface 731a of the first plate 731 is guided so that a portion of the first cover tape 2 from which the first plate 731 is separated is bent, the inclination angle θ1 of the separation unit 720 Can be set smaller than (θ1> θ2).

In the state where the tape support portion 710 is coupled to the base frame 600, the first carrier tape 3 is transferred in the X-axis direction, and a part of the first cover tape 2 is peeled off from the first carrier tape 3 While the pickup of the first part 5 is made by the adsorption nozzle 7a of the head assembly 7 in the first carrier tape 3, at least the tape support 710 and the first carrier tape 3 A portion may vibrate relative to the base frame 600.

Since the tape support portion 710 moves the first carrier tape 3 and the transfer of the first carrier tape 3 must be stably performed while the first component 5 is picked up, the tape support portion 710 and the tape It is designed to minimize the variation in position between the tape support 710 and the first sprocket 211 at the contact point P1 of the first carrier tape 3 and the first sprocket 211. That is, the position change of the tape support portion 710 and the first sprocket 211 with respect to the base frame 600 at the contact point P1 is kept to a minimum.

As described above, the edge portion 710b of the tape support portion 710 passes through the contact point P1 to cross the straight line L1 extending along the transport direction of the first carrier tape 3 Since it is disposed in, the operation of separating a portion of the first cover tape 2 from the first carrier tape 3 may be stably performed while the first carrier tape 3 is being transported. In addition, the first sprocket 211 and the second sprocket 221 are maintained in contact with the first carrier tape 3 at each of the front and rear sides of the separation unit 720 where the separation operation occurs, and the first carrier tape Since the (3) is stably transferred to the separating part 720, vibrations generated when the first cover tape 2 is separated can be minimized.

11 is a cross-sectional view taken along the line XI-XI in the cover tape removal unit 700 of FIG. 10. 12 is a cross-sectional view taken along the line XII-XII in the cover tape removal unit 700 of FIG. 10.

11 and 12, when the first carrier tape 3 is guided by the tape support portion 710 and transported along the X-axis direction, the upper surface of the first carrier tape 3 by the separation portion 720 A portion of the first cover tape 2 attached to is separated. The separating portion 720 is inclined with respect to the transport direction of the first carrier tape 3, so that the first cover tape 2 is separated from one edge 710b of the tape support portion 710.

In FIG. 11, a portion in which the first cover tape 2 is separated from the first carrier tape 3 is a first separation portion 2b (first side), and the first cover tape 2 is a first carrier tape 3 ) Is shown as the first attachment portion 2a (second side portion).

The first separation portion 2b of the first cover tape 2 separated from the first carrier tape 3 is guided by the bending guide portion 730 to move away from the first carrier tape 3 and the tape support portion 710 ) Toward the other edge 710a. The first separation portion 2b of the first cover tape 2 bent by the bending guide portion 730 is folded at the edge of the first carrier tape 3 by the folding guide portion 740. That is, when the first cover tape 2 is attached to the first carrier tape 3, one surface 2b-1 of the first separating portion 2b of the first cover tape 2 facing upward is the first. The first cover tape 2 is folded by the folding guide 740 so that it goes down over the attachment portion 2a and faces the side 3d of the edge of the first carrier tape 3.

The first attachment portion 2a of the first cover tape 2 remains attached to the first carrier tape 3 while a portion of the first separation portion 2b of the first cover tape 2 is folded The other surface 2b-2 of the first separation portion 2b of the first cover tape 2, which was attached to the first carrier tape 3 before being separated from the first carrier tape 3, is a folding guide portion. Towards the side plate 742 of 740.

Since the folded first cover tape 2 is guided and discharged into the inside of the side plate 742 by the side plate 742, a portion of the first cover tape 2 separated from the first carrier tape 3 is taped. It can be prevented from escaping to the outside of the supply device.

In addition, for a period of time after the first cover tape 2 is separated, the first cover tape 2 is attached to the first cover tape 2 which is bent by the bending guide part 730 due to electrostatic phenomenon. The case of moving along may occur. In this case, since the first component moving on the first cover tape 2 falls to the side where the first cover tape 2 is folded, the first carrier tape 3 Do not interfere with progress.

13 is a perspective view schematically showing an operating relationship between the first carrier tape and the first cover tape in the cover tape removal unit 700 of FIG. 10. 14 is a cross-sectional view taken along the line XIV-XIV in the first carrier tape of FIG. 13. 15 is a cross-sectional view taken along the line XV-XV in the first carrier tape of FIG. 13. 16 is a cross-sectional view taken along the line XVI-XVI in the first carrier tape of FIG. 13; 13 to 16, for convenience of description, illustration of some components that have been shown in the previous drawings is omitted.

13 to 16, the first cover tape 2 from the first carrier tape 3 by the separation part 720 disposed in the middle of the path in which the first carrier tape 3 is transferred in the X-axis direction ) Is separated. As shown in FIG. 14, when the first carrier tape 3 reaches the separator 720, a portion of the first cover tape 2 on the surface of the first carrier tape 3 is separated.

Referring to FIG. 15, the first separation portion 2b of the first cover tape 2 separated from the first carrier tape 3 is bent away from the first carrier tape 3. The first cover tape 2 may be bent in a range of 225 degrees or more and 315 degrees or less with respect to the first carrier tape 3.

Referring to FIG. 16, the first separation portion 2b of the first cover tape 2 is folded to the side surface of the first carrier tape 3. In FIGS. 15 to 16, the first attachment portion 2a of the first cover tape 2 is the surface of the first carrier tape 3 while the first separation portion 2b of the first cover tape 2 is bent and folded. Since the parts are picked up from the first carrier tape 3, the first carrier tape 3 and the first cover tape 2 together can be discharged to the outside of the tape feeder. have.

The width of the first carrier tape 3 and the first cover tape 2 may be wider or narrower depending on the size of the components mounted on the first carrier tape 3. In the tape supply device having the above-described configuration, the first attachment portion 2a of the first cover tape 2 remains attached to the first carrier tape 3 and the first separation portion of the first cover tape 2 is maintained. Since (2b) is discharged in a folded state to the side of the first carrier tape 3, even if the width of the first carrier tape 3 and the first cover tape 2 is wide, the increase in the width of the tape supply device is minimized. can do.

This can contribute to increase in productivity per unit area of the component mounting equipment by minimizing the installation space of the tape feeding apparatus when a plurality of tape feeding apparatuses are arranged in parallel in one component mounting equipment.

17A is a cross-sectional view schematically showing an operating state in which the first cover tape is separated from the first carrier tape by the cover tape removal unit 700 of FIG. 10. 17B is a cross-sectional view showing a different angle from FIG. 17A.

Referring to FIGS. 17A and 17B, as shown in FIG. 17A, a portion of the first cover tape 2 is first carrier tape 3 while the first carrier tape 3 passes through the separator 720. It is separated from and becomes the first separation portion 2b, and the remaining portion of the first cover tape 2 becomes the first attachment portion 2a, which remains attached to the first carrier tape 3.

The separating part 720 is inclined with respect to the transport direction of the first carrier tape 3 in the thickness direction. That is, the thickness of the separation portion 720 is formed to be gradually thickened along the transport direction of the first carrier tape 3. Therefore, the separation portion 720 has an inclined surface 720a at the front end facing the first carrier tape 3.

The angle B formed by the inclined surface 720a of the front end of the separating portion 720 relative to the surface of the first carrier tape 3 in order for the first cover tape 2 to be smoothly separated from the first carrier tape 3 ) Is set to be larger than the angle A formed with respect to the surface of the first carrier tape 3 as the first cover tape 2 is peeled from the first carrier tape 3 by the separation portion 720 (B > A).

If, the first cover tape (2) is separated from the first carrier tape (3) by the separation portion 720, the angle (A) formed with respect to the surface of the first carrier tape (3) of the separation portion (720) If the inclined surface 720a of the front end is larger than the angle B formed with respect to the surface of the first carrier tape 3 (A> B), peeling of the first cover tape 2 may not be smoothly performed. In FIGS. 17A and 17B, T denotes the thickness of the separation unit 720.

When the first cover tape 2 is attached to the first carrier tape 3, the position and amount of adhesive applied between the first cover tape 2 and the first carrier tape 3 may be irregular. Therefore, in order to smoothly separate the first cover tape 2 from the first carrier tape 3, as shown in FIG. 17B, the width (W / 2) of the separation portion 720 is that of the first cover tape 2 It should be about half the width (W).

The first attachment portion 2a of the first cover tape 2 can remain attached to the edge of the first carrier tape 3 while the first cover tape 2 is separated from the first carrier tape 3. It should be. Therefore, in order to prevent the first attachment portion 2a from being peeled off from the first carrier tape 3, the angle at which the first cover tape 2 is peeled off from the first carrier tape 3 by the separation portion 720 ( The thickness T of the separation portion 720 may be designed such that C) is smaller than the angle at which the first attachment portion 2a will be separated.

According to the tape supply device having the above-described configuration, the first cover tape 2 is provided by the separation part 720 disposed on a straight line passing through the contact point P1 of the first carrier tape 3 and the first sprocket 211. Since it is separated, the separation operation of the first cover tape 2 can be made precisely and stably.

In addition, after only a portion of the first cover tape 2 is separated from the first carrier tape 3, the separated portion is folded to the side of the first carrier tape 3 and the first carrier tape 3 is Since the first cover tape 2 is transported forward and can be discharged to the outside of the tape supply device, it is possible to omit the mechanical elements for collecting the first cover tape 2 from the carrier tape supply device so that the carrier tape can be omitted. The configuration of the supply device can be simplified.

FIG. 21 is a conceptual view showing a component mounting system S illustrated in FIG. 1. FIG. 22 is a flowchart showing a control procedure of the component mounting system S shown in FIG. 21. In the following, the same reference numerals as above represent the same members.

21 and 22, when the component mounting system S is operated, first the first component reel 8 and the second component reel 8a may be installed on the carrier tape supply device F. At this time, the method of installing the first carrier tape 3 and the second carrier tape 1 on the carrier tape supply device F may be performed in the same manner as described above.

Meanwhile, hereinafter, the case where the component mounting system S operates after installing the first carrier tape 3 and the second carrier tape 1 will be described in detail.

1. When the first carrier tape and the second carrier tape are installed and the carrier tape feeder is working.

When the component mounting system S is operated, the carrier tape supply device F may be installed in the component mounting device D. Specifically, the carrier tape supply device F may be seated on the seating portion D2 and fixed.

When the carrier tape supply device F is seated on the seating portion D2 as described above, the control unit 600b may determine whether the carrier tape supplying device F is correctly seated on the seating portion D2. )

Specifically, when the carrier tape supply device F is seated on the seating portion D2, the connection detection sensor unit 600a may detect whether the carrier tape supply device F and the seating portion D2 are connected.

Particularly, when the carrier tape supply device F is connected to the seating portion D2, the connection detection sensor unit 600a may be switched on. When the switch is turned on as described above, the connection detection sensor unit 600a may generate an on signal and transmit the on signal to the control unit 600b. In addition, when the carrier tape supply device F is seated on the seating portion D2 as described above, the control unit 600b may be connected to the component mounting device D. Specifically, the control unit 600b may be electrically connected to the control unit of the component mounting device D and signals may be exchanged.

When a signal is applied from the connection detection sensor unit 600a and the control unit as described above, the control unit 600b may determine that the carrier tape supply device F is correctly installed in the seating unit D2. At this time, power may be applied to the carrier tape supply device F (step S112).

On the other hand, as described above, if it is determined that no signal is applied from at least one of the connection detection sensor unit 600a and the control unit, the control unit 600b determines that the carrier tape supply device F is not correctly installed. You can.

At this time, the control unit 600b may operate the alarm unit so as to be recognized by an external user or emit a position alignment warning of the carrier tape supply device F to the outside (step S113).

Meanwhile, as described above, when power is applied to the carrier tape supply device F, the control unit 600b may determine whether a signal is applied from the first detection sensor unit 400. (Step S114)

The first detection sensor unit 400 may generate a signal to the outside when the first carrier tape 3 is present. Specifically, when the first carrier tape 3 is installed, light generated from the first detection sensor unit 400 may be blocked by the first carrier tape 3. In this case, the light generated by the first sensing sensor unit 400 is blocked by the first carrier tape 3, so that the first sensing sensor unit 400 generates a signal that the first carrier tape 3 is present. To the control unit 600b.

On the other hand, when the first carrier tape 3 is not present, light generated from the first sensing sensor unit 400 may not be blocked by the first carrier tape 3. At this time, the first detection sensor unit 400 may generate a signal that the first carrier tape 3 does not exist and transmit the signal to the control unit 600b.

When a signal is transmitted to the control unit 600b as described above, the control unit 600b may determine whether the first carrier tape 3 is present. At this time, the control unit 600b may determine whether the first carrier tape 3 does not exist on the first detection sensor unit 400 at the beginning of the operation as described above (step S114).

Specifically, when a signal that the first carrier tape 3 exists in the first detection sensor unit 400, the control unit 600b may control to operate the third driving unit 230a. At this time, the control unit 600b may control the third driving unit 230a to rotate at a second speed (step S118).

On the other hand, if it is determined that the first carrier tape 3 does not exist in the first detection sensor unit 400, the control unit 600b may determine whether the second carrier tape 1 is present (step S115). )

At this time, the second detection sensor unit 500 may detect the presence of the second carrier tape 1 or the first carrier tape 3. At this time, the method for sensing the signal in the second sensing sensor unit 500 is similar to the method for sensing in the first sensing sensor unit 400, so a detailed description thereof will be omitted.

On the other hand, if it is determined that the second carrier tape 1 does not exist, the controller 600b may stop the operation and warn that there is no operation or generate an alarm through the alarm unit (step S124).

On the other hand, when the presence of the second carrier tape 1 is detected in the second detection sensor unit 500 as described above, the control unit 600b may control to rotate the third driving unit 230a at a first speed. Yes (S116 step)

At this time, the third driving unit 230a may rotate the rotating unit 230 while rotating at the first speed. When the rotating part 230 is rotated as described above, the rotating part 230 is coupled to the first transport hole 3b of the first carrier tape 3 to attach the first carrier tape 3 to the first detection sensor part 400. Can be transferred to the side.

Meanwhile, as described above, while the first carrier tape 3 is being transported, the first detection sensor unit 400 may detect the existence of the first carrier tape 3 as described above. At this time, since the method for detecting the first carrier tape 3 by the first detection sensor unit 400 is the same as described above, detailed description will be omitted.

The controller 600b may determine whether the first carrier tape 3 is present based on the result of the first detection sensor unit 400 detecting the first carrier tape 3 (step S117). When the first detection sensor unit 400 detects the presence of the first carrier tape 3, the control unit 600b displays the first carrier tape 3 on the first detection sensor unit 400 based on the result. It can be judged to be located in.

If it is determined as described above, the control unit 600b may control the third driving unit 230a to rotate at the second speed after stopping the driving of the third driving unit 230a. (Step S118) At this time, the first The second speed may be formed differently from the first speed. In particular, the second speed may be smaller than the first speed.

Meanwhile, the control unit 600b may transfer the first carrier tape 3 to the first sprocket 211 by a predetermined amount while rotating the third driving unit 230a at the second speed. (Step S119) At this time, The control unit 600b may transfer the first carrier tape 3 by a predetermined amount by controlling the rotation time or the number of rotations of the third driving unit 230a. However, hereinafter, for convenience of description, the controller 600b will control the rotation time of the third driving unit 230a and focus on the case where the first carrier tape 3 is transferred in a prescribed amount.

The control unit 600b may control the third driving unit 230a to rotate at the second speed for a first time. At this time, when the third driving unit 230a is driven at the second speed for the first time, the first carrier tape 3 may be transferred to the control unit 600b by a predetermined amount.

At this time, a third rotation detection sensor unit 140b is installed in the third driving unit 230a to sense the degree of rotation of the third driving unit 230a. Since the third rotation detection sensor unit 140b is the same or similar to the first rotation detection sensor unit 220c or the second rotation detection sensor unit 320c described above, detailed description thereof will be omitted.

Meanwhile, the control unit 600b may control the third driving unit 230a as described above based on the degree of rotation of the third driving unit 230a measured by the third rotation sensing sensor unit 140b.

When the first carrier tape 3 is transferred as described above, the first carrier tape 3 may be transferred to the first sprocket 211 and the second sprocket 221 after passing through the first detection sensor unit 400. have. At this time, the first sprocket 211 and the second sprocket 221 may be freely rotatable. In particular, when the third driving unit 230a operates as described above, the first transport hole 3b of the first carrier tape 3 may be inserted into the first sprocket 211 and the second sprocket 221.

On the other hand, after transferring the first carrier tape 3 as described above, the control unit 600b may control to stop the third driving unit 230a. (Step S121) At this time, the first carrier tape 3 ) May be coupled to the first sprocket 211 and the second sprocket 221 as described above. In particular, the first marking portion (not shown) of the first carrier tape 3 may be located on the lower surface of the second marking recognition portion E2.

When the position of the first carrier tape 3 is aligned as described above, the second marker recognition unit E2 may recognize the first marker and transmit it to the control unit. At this time, the control unit may transmit the recognized first marker to the controller 600b.

When the first marker is transmitted as described above, the controller 600b may determine whether it is the same as the preset mounting information. (Step S122) At this time, the preset mounting information may include various information. For example, the preset mounting information is the specification, size, and type of the first part 5, the type of the external electronic device used, the production date, the production place, and the specification, manufacturer, and use of the carrier tape supply device F. It may be a variety of information, such as the external electronics possible.

On the other hand, if it is determined that the controller 600b is different from each other after comparing the first marking unit and the preset mounting information as described above, the operation may be stopped or the alarm unit may be operated (step S124).

On the other hand, if it is determined that the preset mounting information is the same as the first marking unit, the controller 600b may store mounting information corresponding to the first marking unit. (Step S123) For example, the first marking If the additional is formed of a QR code as described above, the control unit 600b may store mounting information corresponding to the QR code.

When the storage is completed as described above, the control unit 600b may control to operate the first driving force generator 212a and the second driving force generator 222a. At this time, the first driving force generating unit 212a and the second driving force generating unit 222a may rotate the first sprocket 211 and the second sprocket 221, respectively (step S125).

The control unit 600b may control the third driving unit 230a to stop while controlling the first driving force generating unit 212a and the second driving force generating unit 222a as described above. At this time, the rotating unit 230 may be freely rotatable without stopping with the third driving unit 230a.

In addition, as described above, while the first carrier tape 3 is being transported, the rotating part 230 may be inserted into the first transport hole 3b and rotated passively so as not to interfere with the transport of the first carrier tape 3. .

When the first carrier tape 3 is transported as described above, the first carrier tape 3 is partially peeled from the first carrier tape 3 by the cover tape removal unit 700. You can. In particular, as described above, the first cover tape 2 may be exposed to the outside of the first carrier tape 3 by rotating to one side of the first carrier tape 3.

On the other hand, when the inside of the first carrier tape 3 is exposed as described above while the first driving force generating portion 212a and the second driving force generating portion 222a are operating as described above, the adsorption nozzle D1 is the first. The component 5 can be adsorbed and taken out from the inside of the first carrier tape 3 (step S126). At this time, the first driving force generating portion 212a and the second driving force generating portion 222a are set for a set time. The first carrier tape 3 can be sequentially transported by repeatedly driving and stopping during the operation.

In particular, the first driving force generating unit 212a and the second driving force generating unit 222a may be controlled to stop for a second predetermined time after driving for a first predetermined time. In addition, the first driving force generating unit 212a and the second driving force generating unit 222a may be controlled to alternately perform driving of the first set time and stopping of the second set time.

At this time, the adsorption nozzle D1 may adsorb the first component 5 as described above when the first driving force generating portion 212a and the second driving force generating portion 222a are stopped for the second set time.

Meanwhile, while the above-described operation is in progress, the first detection sensor unit 400 may continuously detect the existence of the first carrier tape 3. In this case, the first detection sensor unit 400 may continuously feedback the control result 600b to the detected result.

(Step S129), that is, the control unit 600b has the first driving force By stopping the generating unit 212a and the second driving force generating unit 222a, the transfer of the first carrier tape 3 can be stopped.

Meanwhile, when the above-described operation is completed, the controller 600b may drive the first driving force generating unit 212a and the second driving force generating unit 222a again at a constant speed. Specifically, the control unit 600b mounts the first component 5 of the remaining portion of the first carrier tape 3 by driving the first driving force generating unit 212a and the second driving force generating unit 222a at a constant speed. It can be supplied to the device (D) (step S129).

At this time, the control unit 600b may control the first driving force generating portion 212a and the second driving force generating portion 222a to transfer the first carrier tape 3 by a predetermined amount. Specifically, the control unit 600b may control the first driving force generating unit 212a and the second driving force generating unit 222a to be repeatedly performed and stopped for a predetermined set time.

In particular, the control unit 600b may control the first driving force generating portion 212a and the second driving force generating portion 222a to be driven for a third set time and stopped for a fourth set time. In addition, the control unit 600b may control to alternately repeat driving and stopping of the first driving force generator 212a and the second driving force generator 222a. At this time, the control unit 600b, as described above, based on the results measured by the first rotation detection sensor unit 220c and the second rotation detection sensor unit 320c, the first driving force generating unit 212a and the second driving force The generation unit 222a can be controlled.

Meanwhile, when the control unit 600b controls the first driving force generating unit 212a and the second driving force generating unit 222a as described above, the first carrier tape 3 may be completely exhausted. At this time, when the first carrier tape 3 is completely exhausted, the carrier tape loading unit 100 may operate to supply the second carrier tape 1 to the rotating unit 230. In particular, since the method for supplying the second carrier tape 1 has been described in detail above, a detailed description will be omitted below.

When the second carrier tape 1 is supplied to the rotating unit 230 as described above, the controller 600b may determine whether a signal is detected by the second sensing sensor unit 500 (step S131). As described above, the detection sensor unit 500 may detect the presence of the second carrier tape 1. In addition, the control unit 600b may determine whether the second carrier tape 1 is present based on the signal transmitted from the second detection sensor unit 500.

At this time, when it is determined that the second carrier tape 1 does not exist based on the signal transmitted from the second detection sensor unit 500, the controller 600b warns that there is no operation or releases the alarm to the outside. In addition, the control unit 600b may stop the first driving force generating units 212a to 3rd driving units 230a to stop the operation of the carrier tape supply unit F. You can.

On the other hand, when it is determined that the second carrier tape 1 exists based on the signal transmitted from the second detection sensor unit 500, the control unit 600b drives the third driving unit 230a at the first speed. (Step S134) In particular, the control unit 600b may control the third driving unit 230a to be driven at the first speed to transfer the second carrier tape 1 (Step S132).

While controlling to drive the third driving unit 230a as described above, the signal detected by the first sensing sensor unit 400 may be transmitted to the control unit 600b.

Specifically, if it is determined that the second carrier tape 1 does not exist on the first detection sensor unit 400 based on the signal of the first detection sensor unit 400, the control unit 600b is the third driving unit 230a ) To be continuously driven at the first speed.

On the other hand, if it is determined that the second carrier tape 1 is present on the first detection sensor unit 400 based on the signal of the first detection sensor unit 400, the control unit 600b is the third driving unit 230a In this case, the second carrier tape 1 may be continuously transported, and then one end of the second carrier tape 1 may be located on the first detection sensor unit 400. have.

When the above operation is completed, the control unit 600b may control the third driving unit 230a to be driven at the second speed. (Step S135) In particular, the control unit 600b rotates the third driving unit 230a. Alternatively, the second carrier tape 1 can be transported by a prescribed amount by controlling the number of rotations and the like. At this time, the control unit 600b may transfer the second carrier tape 1 by a prescribed amount by controlling the third driving unit 230a to rotate at the second speed for the first time as described above. (Step S136)

Meanwhile, when the third driving unit 230a is controlled as described above, the second carrier tape 1 may be transferred to the first sprocket 211 and the second sprocket 221. In particular, the second transport hole (not shown) of the second carrier tape 1 may be coupled to the first sprocket 211 and the second sprocket 221. At this time, the first sprocket 211 and the second sprocket 221 may be passively rotated according to the transport of the second carrier tape 1.

The control unit 600b may control to stop the third driving unit 230a to transfer the second carrier tape 1 in a prescribed amount. (Step S137) At this time, when the third driving unit 230a is stopped, 2 One end of the carrier tape 1 may be located on the second sprocket 221. That is, one end of the second carrier tape 1 may be disposed under the adsorption nozzle D1.

Specifically, as described above, the second marker recognition unit E2 may recognize the second marker and transmit it to the control unit.

The control unit may transmit the second marking unit back to the control unit 600b, and the control unit 600b may determine whether the second mounting unit and the preset mounting information match (step S139). Since the information is the same or similar to that described above, detailed description will be omitted.

If it is determined that the preset mounting information does not match the second marking unit and the second marking unit, the controller 600b may control the alarm unit to emit no work warning or alarm. (Step S141) 600b may stop the operation of the carrier tape supply device F.

On the other hand, when the preset mounting information matches the second marking unit, the controller 600b may store mounting information corresponding to the second marking unit (step S139). Since the mounting information is the same or similar to that described above, detailed description will be omitted.

On the other hand, when the storage of the mounting information is completed as described above, the control unit 600b may control to drive the first driving force generator 212a and the second driving force generator 222a. Specifically, the control unit 600b may control the first driving force generating unit 212a and the second driving force generating unit 222a to repeat driving and stopping.

In particular, the control unit 600b may control the first driving force generator 212a and the second driving force generator 222a to stop for the second predetermined time after driving for the first predetermined time. At this time, during the second set time, the adsorption nozzle D1 can adsorb the second component (not shown) of the second carrier tape 1 and take it out to the outside.

Meanwhile, while the above operation is in progress, the first detection sensor unit 400 may continuously detect the presence of the second carrier tape 1. At this time, the first detection sensor unit 400 may transmit the detected signal to the control unit 600b. The control unit 600b may determine whether the second carrier tape 1 is present based on the signal detected by the first detection sensor unit 400 (step S144).

If it is determined that the second carrier tape 1 is present based on the signal detected by the first detection sensor unit 400, the control unit 600b includes the first driving force generating unit 212a and the second driving force generating unit 222a. ) Can be continuously controlled to operate as described above (step S142).

On the other hand, if it is determined that the second carrier tape 1 does not exist based on the signal detected by the first detection sensor unit 400, the control unit 600b generates the first driving force generating unit 212a and the second driving force. The portion 222a can be driven at a constant speed.

Specifically, the control unit 600b drives the first driving force generating unit 212a and the second driving force generating unit 222a at a constant speed to mount the second component of the remaining portion of the second carrier tape 1 in a component mounting device ( D). (Step S145)

At this time, the control unit 600b may control the first driving force generating portion 212a and the second driving force generating portion 222a to transfer the second carrier tape 1 by a predetermined amount. Specifically, the control unit 600b may control the first driving force generating unit 212a and the second driving force generating unit 222a to be repeatedly performed and stopped for a predetermined set time.

In particular, the control unit 600b may control the first driving force generating portion 212a and the second driving force generating portion 222a to be driven for a third set time and stopped for a fourth set time. In addition, the control unit 600b may control to alternately repeat driving and stopping of the first driving force generator 212a and the second driving force generator 222a. When the first driving force generating portion 212a and the second driving force generating portion 222a are operated as described above, the second carrier tape 1 may be completely drawn out to the second component at the end.
