Description

  The present invention relates to a suppressor, a feeder, a feeder control method, and an electronic component mounting apparatus, and more particularly to an electronic component mounting apparatus that can reliably supply electronic components and has a high operating rate.

In recent years, in the production of circuit boards by mounting electronic components on a printed circuit board, it is desired to improve the operating rate of the electronic component mounting apparatus. For this purpose, it is important to supply the electronic components reliably and complete the replenishment time or the setup change of the electronic components in a short time.
As a conventional technique, a supply tape containing electronic components is inserted, and a third sprocket that engages (fits) with a sprocket hole of the inserted supply tape is driven to be inserted, and is engaged with the sprocket hole. When driving the driving sprocket to move the electronic component to the take-out position, the tip sprocket has a cut sprocket hole cut shorter than the half-moon state, and the cut sprocket hole of the supply tape inserted from the insertion opening is driven by the sprocket. A device that controls the position to engage with the head and performs cueing is described in Patent Document 1 below.

In the description of each drawing, the same reference numerals are assigned to components having the same function, and description thereof is omitted as much as possible to avoid duplication.

The first embodiment of the present invention will be described below. FIG. 1 is a plan view showing a configuration of an embodiment of an electronic component mounting apparatus according to the present invention. The electronic component mounting apparatus 1 has a total of four blocks, that is, two blocks LU and LD on the upper left and lower sides, and two upper and lower blocks RU and RD on the right side, and a control device 80. In the drawing, reference numerals are basically written only for LU blocks.
Each block includes a component supply area 13 in which a feeder cart having a large number of feeders is set, a mounting head 6, a mounting head body 11 that moves the mounting head 6, and a suction holding state of electronic components in the suction head 6.

  Such an operation is performed in four blocks. Therefore, in the center, there are four chutes 5a to 5d for transporting the substrate P, the upper two chutes 5c and 5d are on the upper block substrate transport line U, and the lower two chutes 5a and 5b are on the bottom. A substrate transport line D for the side block is configured. The substrate P is distributed by the delivery unit 7 and carried into the substrate transport line U or D.

FIG. 2 is a perspective view of an embodiment of the feeder cart 50 set in the component supply area 13 of the electronic component mounting apparatus 1 of FIG.
The feeder cart 50 shown in FIG. 2 roughly includes a base portion 51, a feeder fixing portion 52 for fixing a feeder shown in FIG. 4 to be described later, a handle portion 53, and a component supply reel 70 (see FIGS. 8A to 8C). The component supply reel storage unit 54 is provided.
The base portion 51 has four wheel fixing portions 51a for fixing moving wheels (not shown) at four corners, and the feeder cart 50 is fixed when the feeder cart 50 is fixed to the main body of the electronic component mounting apparatus 1. It has a lock pin 51b that is fixed to the floor surface. The feeder fixing portion 52 is provided at the upper portion of the feeder cart 50, and the feeder fixing portion guide 52c guides the cassette fixing portion 35 of the feeder 2 to place the feeder 2 on the feeder base 52a, and the feeder signal connector 52d is connected to the feeder 2 of the feeder 2. The interface unit 36 is connected. The feeder fixing portion connector 52c is regularly arranged on the feeder base 52a so that a large number of feeders can be mounted. A supply tape 60 on which the electronic component 4 is mounted is supplied to each feeder from the supply reel storage section 54 to each feeder.

  At both ends of the feeder base 52a, there are feeder guides 52e that play a role of sliding a cart guide plate (not shown) provided on the main body 1 when inserting the feeder cart into the main body 1. Further, the feeder guide 52 e has a positioning hole 52 b for fixing the feeder cart 50 to the main body 1. Finally, there is a handle portion 53 so that the feeder cart 50 can be moved, and the operator moves the feeder cart 50 in the Y direction which is the direction of the main body 1 by the handle 53a of the handle portion 53 and inserts the feeder cart 50 into the main body. At this time, the front end 53c of the side plate 53b of the handle portion 53 serves as a stopper that prevents the feeder cart 50 from being inserted any further.

FIG. 3 is a diagram illustrating a configuration example of a general supply tape used in the present embodiment.
In the configuration, the supply tape 60 has a carrier tape 62 having a pocket 63 for accommodating the electronic component 4 and a cover tape 61 covering the carrier tape, and the carrier tape 62 has a sprocket (described later) at one end thereof. And a substantially circular sprocket hole (tape feed hole) 64 that fits with the reference tape and moves the supply tape 60 at regular intervals (constant pitch).

  FIG. 4 is a diagram showing the configuration of an embodiment of the feeder of the present invention. The feeder cart 50 (see FIG. 2) is equipped with a plurality of feeders 2. Note that the feeder 2 in FIG. 4 does not show the supply tape 60. Further, in the feeder 2 of FIG. 4, the left side of the screen is the downstream direction (forward direction: the direction of arrow A), and the right side of the screen is the upstream direction (reverse direction: the direction of arrow B). The supply cassette control unit 37 is connected to necessary equipment of the feeder 2 (for example, a tape insertion detection sensor 31, a sprocket drive motor 33, a tape push-in detection sensor 45, a sprocket drive motor 47, etc.) by a control line (not shown). Yes.

The feeder 2 in FIG. 4 fixes the suppressor 38 that presses the supply tape 60 inserted from the insertion port C, the outlet 44 for the suction nozzle of the mounting head 6 to suck electronic components, and the feeder 2 to the component supply cart 50. A cassette fixing part 35 is provided. The suppressor 38 is configured to press the supply tape 60 on the tape chute 2S (see FIG. 5A or 6A) from above so that the sprocket hole 64 does not come off from the teeth 32h at the time of loading. It is. The feeder 2 is provided with a third sprocket 32 for inserting the tip end portion 60 a of the supply tape 60 into the feeder 2 below the suppressor 38. When the third sprocket 32 rotates so as to move the supply tape 60 in the downstream direction, the teeth 32h of the third sprocket 32 fitted to the sprocket holes 64 of the supply tape 60 rotate in the forward direction (A direction). To do. As a result, the supply tape 60 moves in the forward direction and can reach the second sprocket 43. The rotation of the first to third sprockets so as to move the supply tape 60 in the downstream direction is hereinafter referred to as forward rotation. Further, the rotation of the supply tape 60 so as to move in the upstream direction is hereinafter referred to as reverse rotation. In the embodiment of FIG. 4, the three sprockets are installed in order of the third sprocket 32, the second sprocket 43, and the first sprocket 41 from the insertion port C of the feeder 2.
The teeth 32h fitted to the sprocket holes 64 are hereinafter particularly referred to as teeth 32h0. Similarly, the teeth 43h fitted to the sprocket holes 64 are hereinafter referred to as teeth 43h0. Further, since the feeder 2 of FIG. 4 has the tape chute 2S provided horizontally, the teeth 32h0 and 43h0 that fit into the sprocket holes 64 of the supply tape 60 are teeth on a vertical line passing through the rotation center of each sprocket. (See FIGS. 5B, 7A, 6B, and 7B).
Then, when the third sprocket 32 rotates so as to move the supply tape 60 in the downstream direction, the teeth 32h of the third sprocket 32 fitted to the sprocket holes 64 of the supply tape 60 move in the forward direction (A direction). Rotate and move. Accordingly, the supply tape 60 moves in the forward direction and reaches the second sprocket 43, so that the sprocket hole 64 of the tip 60a of the reached supply tape and the teeth 43h of the second sprocket 43 are fitted. The supply tape 60 moves in the forward direction by the rotation of the second sprocket 43 and can reach the first sprocket 41.
Therefore, the first sprocket 41 of the feeder 2 does not push and cuts the cover tape 61 of the supply tape 60 by pulling from the downstream direction.

The feeder 2 also includes a sprocket drive motor 33 that drives the third sprocket 32, and a sprocket drive motor 47 that drives the first sprocket 41 and the second sprocket 43. The supply cassette control unit 37 receives information from the interface 36 for transmitting / receiving signals to / from the main body 1 via a signal transmission / reception cable (not shown) and a signal from a sensor (described later) in the feeder 2. Control and perform signal exchange with the main body 1. The first sprocket 41 and the second sprocket 43 have a sprocket drive motor 47 that simultaneously and synchronously drives each sprocket via a worm gear 46 that meshes with a worm wheel (teeth 41H and 43H) provided concentrically. Similarly, the sprocket 32 has a sprocket drive motor 33 that drives the sprocket 32 via a worm gear 34 that meshes with a worm wheel (teeth 32H) provided concentrically. Note that, for example, the worm gear 46 is geared on the same shaft at a position where it meshes with the teeth 41H and 43H of the respective sprockets.
Further, the feeder 2 includes an operation panel 48 in the vicinity of the insertion slot C of the supply tape 60 and the suppressor 38. In FIG. 4, the operation panel 48 is provided on the surface of the feeder handle 39 for carrying the feeder 2, but may be provided anywhere as long as it can be operated and visually confirmed.

In FIG. 4, the driving sources of the third sprocket 32 and the second sprocket 43 are different and are driven independently. The second sprocket 43 and the first sprocket 41 use the same drive source (sprocket drive motor 47). That is, the supply cassette control unit 37 is a sprocket drive motor based on at least one of the control from the main body 1, the control from the operation panel 48, or the detection signal from the tape insertion detection sensor 31 or the tape push-in detection sensor 45. 33 and 47 are controlled to rotate. The sprocket drive motor 33 transmits the rotational force to the third sprocket 32 via the belt and the worm gear 34. The third sprocket 32 rotates in a predetermined direction at a predetermined rotational speed by the transmitted rotational force.
Here, the third sprocket 32 moves the supply tape 60 downstream on the tape chute 2S in order to fit the sprocket hole 64 of the tip 60a of the supply tape 60 to the teeth 43h0 of the second sprocket 43 of the feeder 2. Push in the direction. Further, the second sprocket 43 performs an operation of pushing into the outlet 44 of the electronic component 4.

Now, during the loading operation, the sprocket hole 64 of the front end portion 60a of the supply tape 60 that has been fitted with the teeth 32h of the third sprocket 32 and moved in the downstream direction reaches the second sprocket 43. The sprocket hole 64 of the tip 60a of the supply tape 60 that has reached the second sprocket 43 is engaged with the teeth 43h of the second sprocket 43, and then the supply tape 60 has a rotational force of the second sprocket 43 having a high rotational speed. To move on the tape chute 2S (transfer by speed difference). In other words, the sprocket hole 64 at the head of the tape 60 moving at a low speed can be caught up and fitted even if the tooth 32h moving at a high speed is initially out of position.
At the time of the above-mentioned connection, the sprocket hole 64 of the tip end portion 60a of the supply tape 60 does not immediately engage with the teeth 43h of the second sprocket 43, and is fitted after sliding slightly (play loss). The tape push-in detection sensor 45 is provided on the downstream side of the second sprocket 43 in order to reliably grasp the tip end portion 60a in consideration of this play loss.
During the loading operation, the supply cassette controller 37 controls the sprocket drive motor 47 to slow down the rotation of the second sprocket 43 when the tape pressing detection sensor 45 detects the leading end 60a of the supply tape 60. Let

The first sprocket 41 mainly drives the supply tape 60. The feeder 2 further includes a pressing mechanism (not shown) for pressing the supply tape 60 against the first sprocket 41 and the mounting head 6 so that the first sprocket 41 is securely fitted to the sprocket hole 64 (see FIG. 3). The suction nozzle has an outlet 44 for sucking the electronic component 4.
The take-out port 44 is provided between the first sprocket 41 and the pushing sprocket 43 of the tape chute 2S.
Further, the pressing mechanism has an exposure mechanism 42 that is exposed from the carrier tape 62 by cutting or peeling the cover tape 61 shown in FIG. 3 in order to take out the electronic component 4 from the supply tape 60. For example, the exposure mechanism 42 includes a cutter that cuts the cover tape 61 and a cover tape guide that guides the cut cover tape so as not to obstruct the removal of the electronic component 4 at the outlet 44 (not shown). . The shape of the cover tape guide portion viewed from above is a triangle with the cutter attachment portion as a vertex.
Therefore, the cut cover tape 61 moves along the cover tape guide while opening on both the left and right sides (direction perpendicular to the paper surface of FIG. 4). On the other hand, the carrier tape 62 having the cut cover tape moves along the bottom surface of the cover tape guide to the take-out port 44 that is a component take-out position.
Further, the main body 1 has a cutting mechanism (not shown) for cutting the carrier tape 62 in a state where the cover tape 61 is cut open and fused in a downstream direction of the first sprocket 41 of the feeder 2 to a predetermined length. Have. The predetermined length is longer than the length between the positions where the push sprocket 43 and the third sprocket 32 are fitted in the sprocket holes 64.
For this reason, since the first sprocket 41 of the feeder 2 is not pressed and pulled from the downstream direction to cover the cover tape 61 of the supply tape 60, the cover tape is not peeled off. As a result, the generation of debris and paper scraps is small, and the generation of dust can be reduced.
Further, as described above, since the cover tape 61 is sent and cut together with the supply tape 60 in the upstream direction, the removal operation and the recovery mechanism of the peeled cover tape, which is necessary in the conventional feeder, are unnecessary.
Further, the first sprocket 41 pulls the leading end portion 60 a of the supply tape 60 to the exposure mechanism 42 when loading the supply tape 60 into the feeder 2. Further, the feeder 2 includes a tape insertion detection sensor 31 that detects the presence or absence of the supply tape between the take-out port 44 and the push sprocket 43 in the upstream direction of the first sprocket 41.

Next, referring to FIG. 4, a loading function for mounting the supply tape 60 on the feeder 2 when the supply tape 60 is not mounted will be described. Here, the loading operation refers to a series of operations in which the supply tape 60 is inserted into the feeder 2 and the supply tape 60 is automatically carried to the take-out port 44, which is a part extraction position of the supply tape 60. This operation is possible even when the electronic component supply device (main body) 1 is being mounted.
When a worker sets a new supply tape 60 on the feeder 2, the reel of the supply tape 60 (component supply reel 70) is used, for example, with a barcode reader connected to the component mounting device in order to prevent a crossover. The barcode 70a attached to is read. This bar code includes information on the electronic component 4 in which the supply tape 60 is accommodated. The read barcode information is transmitted to the main body 1.
The control device 80 (see FIG. 1) of the main body 1 determines whether or not the received bar code information matches the feeder information to be set. If the barcode information and the feeder information match, the control device 80 operates to continue the operation as it is. If the barcode information does not match, the control device 80 outputs an alarm and stops the automatic insertion operation. For example, even if a feed button (described later) on the operation panel 48 is pressed, the sprocket drive motor 33 does not rotate and the third sprocket 32 does not rotate, so that no feeding operation is performed. As a result, cross-over is prevented.

The control device 80 transmits a command to the feeder 2 when the barcode information and the feeder information match. Receiving this command, the feeder 2 continues the loading operation when the operation panel 48 is operated.
That is, at the time of the loading operation, as shown in FIG. 8A, the worker sets the supply tape 60 in the introduction part (component supply reel storage part 54 (see FIG. 2)).
Then, the operator inserts the tip end portion 60a of the supply tape 60 from the tape insertion opening C under the suppressor 38 to the position where the sprocket hole 64 and the sprocket teeth are fitted on the third sprocket 32.
The worker may remove the suppressor 38 and insert it at a position where the teeth 32h0 of the third sprocket 32 and the sprocket hole 64 are fitted, and then attach the suppressor 38.

Next, the worker presses the loading button 105 on the operation panel 48.
The supply cassette control unit 37 of the feeder 2 detects that the loading button 105 of the operation panel 48 has been pressed, and rotates the third sprocket 32 in the forward direction. By this rotation, as shown in FIG. 8B, the supply tape 60 is sent out in the A direction, and the sprocket hole 64 of the front end portion 60 a of the supply tape 60 reaches a position where it is fitted with the teeth of the second sprocket 43. The presence of the suppressor 38 allows the supply tape 60 to be reliably pushed to the second sprocket 43 by the third sprocket 32 as described above.
The second sprocket 43 starts rotating when a predetermined time elapses after the third sprocket 32 starts rotating and the tape insertion detection sensor 31 detects the supply tape 60. This predetermined time is shorter than the time from when the third sprocket 32 rotates until the leading end 60a of the supply tape 60 reaches the fitting position of the second sprocket 43 from the position of the tape insertion detection sensor 31.
The tape insertion detection sensor 31 is installed in the vicinity of the tape chute 2S between the teeth 32h of the third sprocket 32 and the teeth 43h of the second sprocket 43, as shown in FIG.

The rotation speed of the third sprocket 32 in the feeder 2 is lower than the rotation speed of the second sprocket 43. For this reason, the drive sources of the third sprocket 32 and the second sprocket 43 are different and are driven independently. Further, after the supply tape insertion operation is completed, the third sprocket 32 stops rotating, and the second sprocket 43 and the first sprocket 41 rotate during the normal component mounting operation.
When the sprocket hole 64 of the supply tape 60 and the teeth 43h of the second sprocket 43 are fitted, the rotation of the second sprocket 43 is faster than the rotation of the third sprocket 32, so the supply tape 60 is synchronized with the rotation of the second sprocket 43. To do. This is because, as shown in FIGS. 5B and 7A, the third sprocket 32 has a shape in which the teeth 32 h are less likely to be caught in a round tooth shape such as a circular hill. For this reason, the sprocket hole 64 has a greater resistance to catching the teeth 43h of the second sprocket 43 than the teeth 32h of the third sprocket 32 (see FIGS. 6B and 7B). The second sprocket 43 moves according to the rotation. In FIG. 5B and FIG. 6B, the tape chute 2S is not shown.

As described above, the rotation of the third sprocket 32 is slower than the rotation of the second sprocket 43 during the supply tape insertion operation. For this reason, the third sprocket 32 incorporates a one-way clutch 32C and rotates in the direction in which the supply tape 60 is inserted (forward direction, the direction indicated by arrow A), but in the reverse direction (the direction indicated by arrow B). Does not rotate.
Furthermore, the teeth 32h of the third sprocket 32, as shown in FIGS. 5A, 5B, 7A, the height _{T 3} smaller than the thickness _{t 2} of the carrier tape 62, and a circular mound-like or the like, without corners It has a gentle curved surface. Further, the teeth 43h of the second sprocket 43, FIG. 6A, as shown FIG. 6B, FIG. 7B, the height _{T 2} greater than the thickness _{t 2} of the carrier tape 62, and, as compared with the teeth 32h, the pin-shaped It has an acute angle shape such as.
In FIG. 5A or 6A, the tape chute 2S is a guide that is provided generally horizontally above the feeder 2 and moves the supply tape 60 to the tape chute 2S. The supply tape 60 moves while sliding on the tape chute 2S of the feeder 2.

As a result, at the time of loading, when the sprocket hole 64 of the supply tape 60 is engaged with the teeth 43h of the second sprocket 43, the supply tape 60 moves according to the rotation of the second sprocket 43.
Accordingly, the feeder 2 has a large distance between the third sprocket 32 and the second sprocket 43, and the fitting of the teeth of the second sprocket 43 and the sprocket holes 64 and the third sprocket due to the feed hole accumulated pitch error of the supply tape 60. Even when the 32 teeth and the sprocket holes 64 cannot be fitted at the same time, the supply tape 60 can be automatically loaded.
Thereafter, the supply cassette control unit 37 of the feeder 2 stops the rotation of the third sprocket 32.

In the feeder 2 shown in FIG. 4, a sprocket drive motor 47 that drives the second sprocket 43 when the first sprocket 41 is driven is a servo motor and is servo-controlled by the supply cassette control unit 37. The sprocket drive motor 33 that drives the third sprocket 32 is a DC motor and is open-controlled by the supply cassette control unit 37.
The first sprocket 41 is a feed mechanism that mainly functions as a feed dog that determines feed positioning accuracy. For example, the first sprocket 41 can improve the posture of the supply tape 60, the stability of travelability (straightness), and the robustness by the double sprocket method combined with the second sprocket 43.
Further, the second sprocket 43 is a delicate insert that inserts the leading end 60a of the supply tape 60 into a tape processing section (tape indentation detection sensor 45, exposure mechanism 42, outlet 44, etc.) downstream of the second sprocket 43. This is a feed mechanism for feed control. For example, when the supply tape is loaded, the second sprocket 43 finely controls the loading operation of the leading end portion 60a of the supply tape 60 to the exposure mechanism 42 by a servo motor drive capable of ensuring an ultra-low speed feed torque. The second sprocket 43 performs a subsidiary assisting operation of the first sprocket 41 after the leading end 60a of the supply tape 60 reaches the first sprocket 41.
The third sprocket 32 is a feed mechanism that moves the supply tape 60 in the downstream direction until the tape pressing detection sensor 45 detects the supply tape 60. The rotation speed of the third sprocket 32 is about half of the rotation speed of the second sprocket 43 when the supply tape is loaded. As a result, even if the accumulated tape hole pitch error at the time of loading tape loading is large, the influence can be absorbed, and the teeth 43h of the second sprocket 43 are securely engaged with the sprocket holes 64 of the feeding tape 60. can do. Further, since the tape 60 is fitted to the round sprocket teeth of the third sprocket 32, the tape 60 runs while sliding on the sprocket teeth to some extent, but the third sprocket 32 rotates while being pulled by the tape 60 by the one-way clutch 32C. The tape 60 can run with almost no resistance.
In addition, the first sprocket 41 and the second sprocket 43 are arranged closest to each other, and the span is not affected by the accumulated pitch error of the sprocket holes 64 of the supply tape 60.
As described above, the sprocket drive motor 47 that drives the first sprocket 41 and the second sprocket 43 is a servo motor to enable acceleration / deceleration control, speed control, and torque control necessary in the tape processing sequence. At the same time, the same drive source was used. The tape processing sequence will be described later with reference to the timing chart of FIG.

In FIG. 4, the supply tape 60 is driven so as to be pulled by the drive sprocket 41 when the normal electronic component 4 is taken out, so that the cover tape is also cut reliably. However, when the supply tape 60 is loaded (inserted into the feeder), the supply tape 60 is pushed into the cutter of the exposure mechanism 42 by the push sprocket 43 from the front end portion 60a. For this reason, when the supply tape 60 is moved and pressed at the speed at the time of the electronic component take-out operation, the acceleration serving as the pressing force is large. As a result, since the speed at which the supply tape 60 moves is fast, the cover tape 61 may not be cut well. Therefore, before the tip 60a of the supply tape 60 reaches the cutter position, the sprocket drive motor 47 is controlled to insert the supply tape 60 into the cutter of the exposure mechanism 42 at a low speed and a low acceleration.
That is, when the tape indentation detection sensor 45 detects the supply tape 60, the supply cassette control unit 37 stops the rotation of the sprocket drive motor 33 and controls the sprocket drive motor 47 to control the exposure mechanism 42 at low speed and low acceleration. Insert into the cutter.
As a result, in the exposure mechanism 42, the cover tape 61 can be reliably cut without buckling the supply tape 60, the supply tape 60 can be moved, and the leading pocket 63 can be positioned at the outlet 44 of the electronic component 4. it can.

Next, the loading operation of the supply tape 60 to the feeder 2 will be described in more detail with reference to FIGS. 4, 8A, 8B, and 9. FIG. FIG. 9 is a diagram showing an operation timing chart of each part in this operation.
(A) is operation | movement of the sprocket drive motor 47, and a vertical axis | shaft shows speed. In the speed (a), a positive speed indicates movement of the supply tape 60 in the direction of arrow A (forward direction) shown in FIG. 4, and a negative speed indicates movement in the direction of arrow B (reverse direction) shown in FIG. .
(B) shows the presence or absence of detection by the tape insertion detection sensor 31 with “Yes” at the High level and “No” at the Low level.
(C) indicates the presence or absence of detection by the tape pressing detection sensor 45 with “Yes” indicating High level and “No” indicating Low level.
(D) indicates ON / OFF of the operation of the sprocket drive motor 33, “ON” indicates a high level, and “OFF” indicates a low level.
(E) shows ON and OFF of the loading SW 105 (see FIG. 10A) of the operation panel 48, “ON” indicates a high level, and “OFF” indicates a low level.

Hereinafter, each step will be described with reference to FIG. Here, the tape insertion detection sensor 31 and the tape push-in detection sensor 45 constantly monitor the presence or absence of a tape, and output a detection signal to the supply cassette control unit 37 when the tape insertion detection sensor 31 and the tape insertion detection sensor 45 change from non-existence to presence / absence. .
First, the preloading operation will be described.
The worker removes the suppressor 38, inserts the tip 60a of the supply tape 60 onto the tape chute 2S, and attaches the suppressor 38 from above so that the teeth 32h0 of the third sprocket 32 and the sprocket hole 64 are fitted. .
Next, the worker presses the loading SW 105 of the operation panel 48.

<State (i)>
When the loading SW 105 is turned on, the supply cassette control unit 37 turns on the loading SW 105 if the detection results of the tape insertion detection sensor 31 and the tape push-in detection sensor 45 are both “no”. After a predetermined interval time T1 has elapsed, the sprocket drive motor 33 is turned on. The timer is started simultaneously with the ON operation of the sprocket drive motor 33.
<State (ii)>
The supply cassette control unit 37 turns off the sprocket drive motor 33 after the timer has elapsed a predetermined time T0.
<State (iii)>
The supply cassette control unit 37 checks whether the tape insertion detection sensor 31 is “present” or “not present” after a predetermined interval time T2 has elapsed after turning off the sprocket drive motor 33.
When the detection result of the tape insertion detection sensor 31 is “none”, the supply cassette control unit 37 keeps the sprocket drive motor 33 OFF and ends the preloading operation.
<State (iv)>
When the detection result of the tape insertion detection sensor 31 is “present”, the supply cassette control unit 37 turns on the sprocket drive motor 33 and starts the rotation operation of the sprocket drive motor 47 (in step S1). Migration).

<Step S1>
At this time, the supply cassette control unit 37 rotates the sprocket drive motor 47 in accordance with a preset tape feed amount. Further, the supply cassette control unit 37 monitors the detection result of the tape pressing detection sensor 45 while the supply tape 60 is moving (tape feeding).
<State (v)>
When the detection result of the tape push-in detection sensor 45 is “Yes”, the supply cassette control unit 37 slows down the sprocket drive motor 47 (OFF) without waiting for completion of the predetermined stroke movement, and the sprocket The sprocket drive motor 33 that has been rotating in conjunction with the drive motor 47 is turned off.
In addition, the supply cassette control unit 37 turns off the feeder 2 when the detection result of the tape pressing detection sensor 45 remains “none” even after the rotation operation according to the preset tape feed amount is completed. Stop abnormally and turn off the sprocket drive motor 33.
That is, in step S1, the sprocket drive motors 47 and 33 rotate together, and the supply tape is inserted into the feeder 2. Then, when the tape pressing detection sensor 45 detects the leading end portion 60a of the supply tape 60, the rotation of the sprocket drive motor 33 is stopped, and the sprocket drive motor 47 is forcibly stopped. Further, even if a predetermined amount of feeding (a predetermined amount of rotation) is performed, if the tape pressing detection sensor 45 does not detect the leading end portion 60a of the supply tape 60, it abnormally stops.

<Step S2>
The supply cassette control unit 37 waits for a predetermined interval time T3 after the rotation of the sprocket drive motor 47 is stopped.
<State (vi)>
The supply cassette control unit 37 performs the reverse feed operation of the sprocket drive motor 47 at the minimum pitch (taping standard: 1 mmP) after a predetermined interval time T3 has elapsed until the detection result of the tape push-in detection sensor 45 becomes “None”. repeat.
<State (vii)>
The supply cassette control unit 37 stops the reverse feed operation of the sprocket drive motor 47 when the detection result of the tape pressing detection sensor 45 becomes “none”.
The supply cassette control unit 37 proceeds to step S3 after a predetermined interval time T4 has elapsed from the state (vii).
That is, in step S2, in consideration of the overrun amount in step S1, the position of the leading end 60a of the supply tape 60 is determined, and the tape pressing detection sensor 45 no longer detects the supply tape (out of the detection range). The supply tape 60 is returned by the reverse rotation operation with the minimum pitch feed. At this time, the sprocket drive motor 47 rotates in reverse at the minimum pitch, but the sprocket drive motor 33 stops rotating (OFF). The third sprocket 32 is not reversed by the one-way clutch 32C, but the return amount is very small (minimum pitch) and the height of the teeth 32h of the third sprocket 32 is low. The supplied supply tape 60 slides and moves in the downstream direction on the tape chute 2S by the thrust of the sprocket drive motor 47.

<Step S3>
The supply cassette control unit 37 rotates the sprocket drive motor 47 at a predetermined speed with a preset step S3 feed drive waveform, and performs a predetermined amount of high-speed tape feed operation (single feed). The predetermined amount is a feed amount from the position where the tip end portion 60a is stopped in step S2 to the position immediately before reaching the cutter blade of the exposure mechanism 42.
That is, in step S3, the leading end portion 60a of the supply tape 60 is fed to the position immediately before the cutter blade of the exposure mechanism 42 by a single feed operation of a predetermined amount. This is because the position of the tip end portion 60a is determined because the tip end portion 60a stops at a predetermined position in step S2. Since the distance between the cutter blade and the predetermined position is determined by the design dimensions, the supply tape 60 can be moved to the position immediately before the cutter blade if the supply tape is fed in the downstream direction by the length.

<Step S4>
The supply cassette controller 37 rotates the sprocket drive motor 47 with a preset step S4 feed drive waveform to perform a tape feed operation (one feed).
In this step S4 feed driving waveform, the supply cassette control unit 37 rotates the sprocket drive motor 47 at an ultra-low speed and an ultra-low acceleration.
That is, in step S4, “insert → cover tape cutting” (Russell process) is performed in the supply tape insertion sequence of the exposure mechanism 42 to the cover tape cutting zone. For example, the supply cassette control unit 37 rotates the sprocket drive motor 47 at an ultra-low speed and an ultra-low acceleration, and sends it once at a predetermined amount. As a result, since a predetermined feeding operation is performed at an ultra-low speed and an ultra-low acceleration, the cover tape 61 can be opened in a russell shape without peeling off from the supply tape 60.

<Step S5>
The sprocket drive motor 47 is rotated by a predetermined feed amount and a predetermined number of feeds in accordance with the part library setting (feed pitch) of the parts stored in the supply tape 60.
That is, in step S5, a total of a predetermined number of pitch feeding operations are performed to cue the position of the pocket 63 of the tip end portion 60a of the supply tape 60 to the suction position (the outlet 44). The feed amount and the number of feeds at this time use a data table determined in advance for each feed tape feed pitch. Note that the data table is built in the control device 80 of the main body 1, and the supply cassette control unit 37 captures and uses these necessary information via the feeder signal connector 52d.

Next, the operation panel of the feeder of the present invention will be described with reference to FIGS. 10A, 10B, 10C, and 10D. FIG. 10A is a diagram illustrating an example of the operation panel surface 100 of the operation panel 48 of the feeder 2 according to the present invention.
The worker selects a lane to be selected on the operation panel surface 100 and presses the lane selection key 102 to select the lane. Next, when the worker presses the loading button 105 for 1 sec or longer, the supply cassette control unit 37 recognizes the operation and selects a lane.
Further, the supply cassette controller 37 feeds the supply tape 60 in the forward direction while the worker is pushing the feed button 103, and reverses the supply tape 60 while the worker is pushing the return button 104. Send to. Further, the supply cassette control unit 37 starts the loading operation of the feeder 2 when the worker presses the loading button 105.
In addition, the digital display unit 101 displays which lane is selected and whether a loading operation or an unloading operation is being performed. As described above, the feeder usually has two left and right lanes, and can each supply one supply tape.

10B to 10D are diagrams showing details of the digital display unit 101 of FIG. 10A.
The display on the digital display unit 101 is 7-segment display during the loading operation. The display continues for the predetermined time (for example, for 0.5 sec), and is repeated in the order of FIG. 10B → FIG. 10C → FIG. 10D → FIG. 10B →.
If the dots 113, 123, and 133 are displayed, the first lane is selected. If the dots 114, 124, and 134 are displayed, the second lane is selected.

When the above-described loading operation is performed in a state where the component supply cart 50 is set in the main body 1, the main body 1 can start the mounting operation upon receiving completion of the loading operation from each feeder.
On the other hand, when the above-described loading operation is performed in a state where the component supply cart 50 is not set in the main body 1, after the loading operation is completed, the component supply cart 50 is set in the main body and the mounting process by the main body is performed. it can.
Moreover, if the component supply cart 50 is set in the main body 1, the main body can immediately shift to the mounting operation.

As described above, according to the embodiment of FIGS. 1 to 10D, when a supply tape is newly inserted into the feeder, even if there is an accumulated pitch error between the sprocket holes, the drive for moving the electronic component to the outlet is performed. A highly reliable feeder, a feeder control method, and an electronic component mounting device capable of performing control that can surely fit the sprocket and the sprocket hole of the supply tape can be realized. Furthermore, it is possible to greatly reduce the parts replacement time at the time of setup change and the parts replenishment time at the time of shortage.
Furthermore, the tape feed by the first and second sprockets is stable, the tape does not peel off, there is no disturbance, and the feed position (for example, the position of the electronic component 4 at the outlet 44) is robust. improves.
In the above embodiment, the operator operates the operation panel to start the loading operation, but the electronic component mounting apparatus 1 may automatically start the loading operation.

Finally, when the above-described loading operation is performed in a state where the parts supply cart 50 is set in the main body 1, the main body 1 can receive the loading operation completion from each feeder and start the mounting operation. .
On the other hand, when the above-described loading operation is performed in a state where the component supply cart 50 is not set in the main body 1, after the loading operation is completed, the component supply cart 50 is set in the main body and the mounting process by the main body is performed. it can.
Moreover, if the component supply cart 50 is set in the main body 1, the main body can immediately shift to the mounting operation.
In this embodiment, the distance between the detection position of the tape pressing detection sensor 45 and the extraction position of the outlet 44 by the suction nozzle of the mounting head 6 is known. Accordingly, when the electronic component 4 is housed in the leading pocket 63, the tape pressing detection sensor 45 detects the leading end 60a of the supply tape 60, thereby mounting the pocket 63 at the leading (tip 60a) tape. The distance to the take-out position by the suction nozzle of the head 6 is determined. This is because, if the sprocket teeth 43h of the second sprocket 43 are fitted in the sprocket holes 64 of the supply tape 60, the positions of the pockets 63 can be known from the positions of the sprocket holes 64, that is, the pockets 63 at the head of the tape. Thus, the pocket 63 can be moved to the take-out position of the outlet 44 (tape feed) and stopped to perform a cueing operation in preparation for taking out the parts.
Not limited to this, after the pocket 63 at the beginning of the tape is stopped at the take-out position as described above, the pocket 63 at the take-out position of the take-out port 44 is imaged each time it is sent by one pitch with the camera provided in the mounting head 6. Alternatively, it may be recognized and recognized from the captured image whether the electronic component 4 is stored in the pocket 63. In other words, when the pocket 63 changes from the absence of a part to the presence of a part by the image recognition process, the tape feeding is stopped and the cueing is performed. By doing in this way, even when the electronic component 4 is not stored in the leading pocket 63, the electronic component 4 can be taken out by taking out with the suction nozzle of the first mounting head 6 loaded with the new tape 60. .
Further, the position of the pocket 63 itself or the electronic component 4 in this pocket 63 in the component supply area 13 is grasped by a recognition process from the captured image, and this grasped position is determined by the mounting head 6. The suction nozzle may be positioned when taking out the parts. Also, without cueing by recognizing the presence or absence of a component in the pocket 63, when the leading pocket 63 is stopped at the component extraction position, the component extraction position is imaged with a camera to recognize the position of the component or the pocket 63 itself. It may be processed and grasped, and the position for picking up the components of the suction nozzle of the mounting head 6 may be determined at this position.
In the present embodiment, the exposure mechanism that exposes the electronic component 4 by opening the cover tape 61 above the pocket 63 in the component extraction portion by performing the Russell process has been described. However, the present invention is not limited to this, and the present invention can be applied to a separation mechanism that removes the cover tape 61 from the supply tape 60 and exposes the electronic component 4.

The second embodiment of the present invention will be described below. Also in the second embodiment, the electronic component mounting apparatus 1 described in FIG. 1, the feeder cart 50 described in FIG. 2, the supply tape 60 described in FIG. 3, the feeder 2 shown in FIG. 4, and FIGS. 5B to 5C. The third sprocket shown and the second sprocket shown in FIGS. 6B to 6C are used.
This unloading operation is an operation in which the in-process supply tape 60 that has already been loaded in the feeder 2 runs backward, can be removed from the feeder 2 and collected. By the cover tape processing method (Russell processing) of the exposure mechanism 42 described in the first embodiment, it is possible to move the supply tape in the reverse direction without being caught by the cover tape, and to greatly reduce the part replacement time at the time of the setup change. Can do.

FIG. 11 is a diagram for explaining an embodiment of the unloading operation in the feeder according to the present invention.
First, the worker removes the suppressor 38 and operates the lane selection key 101 on the operation panel 48 to select a desired lane.
Thereafter, the worker presses the return button 104 on the operation panel 48. For example, in the operation panel 48 of FIG. 10A, the worker presses the loading button 105, and simultaneously presses the return button 104 within 1 sec while pressing. By continuing this simultaneous pressing state for 1 sec or longer, the supply cassette control unit 37 of the feeder 2 starts an unloading operation.
As a constraint condition for the supply cassette control unit 37 to start the unloading operation, the tape push-in detection sensor 45 must be in a state where the supply tape is “present”.

The supply cassette controller 37 detects that the return button 104 has been pressed, and moves the supply tape 60 in the reverse direction (in the direction of arrow B) by a predetermined amount according to a preset reverse feed amount. The preset reverse feed amount is determined in consideration of the amount by which the front end 60a of the supply tape 60 (the tape length up to the front of the cutting mechanism of the main body 1 can be taken out) can be taken out.
Since the front end portion 60a of the supply tape 60 moves in the reverse direction to the position where it is disengaged from the second sprocket 43 (upstream direction of the second sprocket 43), the worker at this point moves the supply tape 60 forward (upstream direction). To remove the supply tape 60 from the feeder 2.

  When the supply cassette control unit 37 detects that at least one button of the operation panel 48 is pressed during the operation of moving the supply tape 60 in the reverse direction, the supply cassette 60 moves the supply tape 60 in the reverse direction. The unloading operation to move to is forcibly interrupted.

12A to 12C are diagrams showing details of the digital display unit 101 in FIG. 10A.
The display on the digital display unit 101 is 7-segment display during the unloading operation. The display continues for the predetermined time (for example, for 0.5 sec), and is repeated in the order of FIG. 12A → FIG. 12B → FIG. 12C → FIG. 12A →.
If the dots 213, 223, and 233 are displayed, the first lane is selected, and if the dots 214, 224, and 234 are displayed, the second lane is selected.

In Example 2 of the above-described unloading operation, the cover tape was processed by the cover tape processing method (Russell process). However, in this embodiment, any exposure mechanism that cuts the cover tape can be unloaded.
Further, in the above-described second embodiment, the two-drive system is used in which three sprockets are driven by two drive motors. However, this embodiment may be a three-drive system in which three sprockets are driven by three drive motors.

  As described above, according to the embodiment of FIGS. 1 to 7A, FIG. 11, FIG. 12A, FIG. 12B, and FIG. 12C, when the supply tape is newly inserted into the feeder, the feeder 2 has already been loaded. The in-process supply tape 60 can be quickly and easily removed in the upstream direction. As a result, it is possible to greatly reduce the parts replacement time at the time of setup change and the parts replenishment time at the time of shortage.

  In the first and second embodiments, the operator operates the operation panel to start the loading operation. However, the electronic component mounting apparatus 1 may automatically start the loading operation.

The third embodiment of the present invention will be described below. Also in the third embodiment, the electronic component mounting apparatus 1 described in FIG. 1, the feeder cart 50 described in FIG. 2, the supply tape 60 described in FIG. 3, the feeder 2 illustrated in FIG. 4, FIGS. The third sprocket shown in FIG. 7A and the second sprocket shown in FIGS. 6B to 6C and 7B are used.
In this loading operation, the next supply tape 60 ′ is set in addition to the supply tape 60 of the feeder 2 that has already been loaded with the electronic component 4 and is used for component mounting, and the supply tape 60 currently in use disappears. Then, the next supply tape 60 ′ is automatically loaded.

14A to 14D are diagrams for explaining an embodiment of the loading operation in the feeder of the present invention. 14A to 14D, the supply tape 60 is already set in the feeder, and the electronic component mounting apparatus 1 (see FIG. 1) is continuing the component mounting operation.
As shown in FIG. 14A, the worker first removes the suppressor 38, lifts the supply tape 60 currently in use, and passes over the suppressor 38. Next, the tip 60a ′ of the supply tape 60 ′ to be used next is inserted on the tape chute 2S, and the suppressor 38 is attached from above so that the teeth 32h0 of the third sprocket 32 and the sprocket hole 64 are fitted. .
Note that the control device 80 of the electronic component mounting apparatus 1 determines whether or not it matches the feeder information to be set based on the received barcode information. If the barcode information and the feeder information match, the control device 80 operates to continue the operation as it is. If they do not match, the control device 80 outputs an alarm, alerts the worker, and reserves the supply tape 60 ′. Is not recognized as being set in the feeder 2.

When the end portion 60 "of the supply tape 60 in use enters the feeder 2 and passes through the tape insertion detection sensor 31, the tape insertion detection sensor 31 detects the supply tape 60" none "and controls each time the detection is made. The control device 80 determines that the end portion 60 "of the supply tape 60 has passed when the supply tape 60" no "state continues for a predetermined feed amount.
Next, when the unloaded part of the electronic tape 4 of the supply tape 60 in use reaches the outlet 44, the control device 80 recognizes the occurrence of a continuous suction abnormality due to no parts. For example, the control device 80 recognizes that there is no electronic component when the suction abnormality continues three times (detected by recognition of a sensor mounted on the mounting head 6 (not shown) or the component recognition camera 19).
The control device 80 performs standard abnormality processing when the tape insertion detection sensor 31 does not detect the passage of the end portion 60 ″ and recognizes the occurrence of continuous suction abnormality due to the absence of components.
However, when the tape insertion detection sensor 31 detects the passage of the end portion 60 ″ and recognizes the occurrence of a continuous suction abnormality due to no parts, the control device 80 detects the electronic parts of the supply tape 60 in use. It is determined that it has been used up, the subsequent operation is performed, and the component mounting operation is continued.
(1) Forced feeding operation of the supply tape 60 in use (2) Automatic loading operation of the next supply tape 60 ′

First, (1) the operation of forcibly feeding the supply tape 60 in use will be described with reference to FIG. FIG. 15 is a view for explaining an embodiment of the forced delivery operation in the feeder of the present invention.
As described above, when it is determined that the electronic parts of the supply tape 60 in use are used up, the control device 80 forcibly sends out the supply tape 60 in use in the forward direction.
For example, the control device 80 controls the supply cassette control unit 37 of the feeder 2 to continuously rotate the sprocket drive motor 47 in the forward direction (arrow A direction) at a high speed and discharge the supply tape 60 at a stretch. The supply tape 60 cannot be driven if the teeth 41h of the first sprocket 41 are disengaged. However, the supply tape 60 is discharged in the direction of arrow A due to the inertia due to the high-speed continuous rotation and the pressing force of the next supply tape 60 ′ that is fed later. .

Next, (2) the automatic loading operation of the next supply tape 60 ′ is started.
However, the supply cassette control unit 37 executes the preloading operation according to a command from the control device 80, not when the loading SW 105 is turned on. That is, the supply cassette control unit 37 receives the activation of the automatic loading operation from the control device 80, rotates the sprocket activation motor 33, checks the tape insertion detection sensor 31 after a predetermined time, and detects the supply tape 60. If it is, the loading operation is continued continuously as it is, and the loading operation is executed. The supply cassette control unit 37 checks the tape insertion detection sensor 31 after a predetermined time has elapsed, and if the supply tape 60 is not detected, does not start the loading operation, outputs an alarm, and performs the loading operation. Discontinue.
As for the automatic loading operation, the operations (see FIG. 9) of the state <i> to the state <iv> described in the first embodiment of the present specification are executed, and the process proceeds to step S1. The subsequent operation is as described with reference to FIG.
During the forced delivery operation, “tr” indicating that the forced delivery operation is being performed is displayed on the digital display unit 101 of the operation panel 48 as shown in FIG. 16A or 16B. 16A to 16C are diagrams showing an embodiment of the digital display unit on the operation panel surface of the operation panel of the feeder according to the present invention.
Further, when the worker presses any button on the operation panel 48 during the forced delivery operation or the automatic loading operation, the operation is interrupted in the middle.

  Next, this embodiment will be described with reference to the flowchart of one embodiment of the automatic loading operation in the electronic component mounting apparatus of the present invention shown in FIG. 13 is executed by the control device 80 by controlling each device of the main body 1, the supply cassette control unit 37 of the feeder 2, and other devices.

In step S801, it is determined whether a continuous suction abnormality (no component) has occurred. If not, the process proceeds to step S888, and normal processing is executed. If it occurs, the process proceeds to step S802.
In step S802, it is determined whether or not the tape insertion detection sensor 31 has detected the end portion 60 ". If not, the process proceeds to step S888 to execute normal processing. The end portion 60" is detected. If so, the process proceeds to step S803.
In step S802, the control device 80 outputs a forced feed command ((1) forced feed command of the used supply tape 60) to the supply cassette control unit 37 of the corresponding feeder 2, and starts a forced feed operation.
In step S804, it is monitored whether the forced sending command is cleared. If cleared, the process proceeds to step S805. If not, the process proceeds to step S888, and normal processing is executed. Occurs when any button on the operation panel 48 is pressed by the operator. Also, for example, clearing of the forced delivery command occurs when there is an abnormality in the feeder 2 during the forced delivery operation.

In step S805, it is checked whether the feeder 2 has an abnormality.
In step S806, if there is an abnormality, the process proceeds to step S888, and the abnormality process is executed. If not, the process proceeds to step S807.
In step S807, the detection information of the tape insertion detection sensor 31 is confirmed.
In step S808, if the tape insertion detection sensor 31 detects that the supply tape is present, the process proceeds to step S809. If there is no supply tape (no detection), the process proceeds to step S888. Execute the process.

In step S809, the control device 80 outputs a loading command (command) ((2) automatic loading operation of the next supply tape 60 ′) to the supply cassette control unit 37 of the corresponding feeder 2, and starts the automatic loading operation. .
In step S810, it is monitored whether or not the automatic loading command is cleared. If cleared, the process proceeds to step S811, and if not, the process proceeds to step S888, and normal processing is executed. Occurs when any button on the operation panel 48 is pressed by the operator. For example, clearing of the automatic loading command occurs when there is an abnormality in the feeder 2 during the loading operation.

In step S811, it is checked whether the feeder 2 has an abnormality.
In step S812, if there is an abnormality, the process proceeds to step S888, and the abnormality process is executed. If not, the process proceeds to step S813.
In step S813, the state transits to a suckable state, and suction of the electronic component 4 is started.

  According to the third embodiment described above, the worker does not need to wait for the next supply tape to be set after the current tape is exhausted, and at any time before the supply tape 60 is exhausted, the next time it is convenient. Since the supply tape 60 'can be set efficiently, the work can be efficiently performed and the loading is automatically executed, so that the part replacement time during the setup change can be greatly shortened.

  The tape loading suppressor mechanism of the feeder of the electronic component mounting apparatus of the present invention will be described with reference to FIGS. Details of the suppressor used in the first to third embodiments will be described as a fourth embodiment of the present invention.

FIG. 17 is a three-view diagram (a front view, a plan view, and a side view) for explaining the configuration of a tape loading suppressor (tape holding plate) used in the first to third embodiments. FIG. 18 is a three-view drawing (front view, plan view, side view) showing an embodiment of the presser member. FIG. 19 is a three-view drawing (front view, plan view, side view) showing an embodiment of the lever portion. 17 to 18, the left direction on the paper is the forward direction A, and the right direction on the paper is the reverse direction B.
The suppressor 90 has a function of pressing the supply tape 60 inserted from the insertion port C, for example, similarly to the suppressor 38 shown in FIG. That is, the suppressor 90 is configured to be detachable from the tape chute 2 so as to be pressed from above on the tape chute 2S (see FIG. 5A or 6A) so that the sprocket hole 64 is not detached from the teeth 32h.
As shown in FIG. 17, the suppressor 90 includes a lever member 91, a pressing member 95, and a spring 93.

  The lever member 91 includes a lever portion having a fulcrum, a force point, and an action point, a lever joint 902 attached to the force point side of the lever portion, and a lever movable portion 91-1 (the lever member 901 and the horizontal plate 906). . The lever portion includes a rotating shaft 905 attached to the fulcrum, a fixing portion 909 for attaching one end of the spring 93 to the force point, and a bearing 904 attached to the operating point.

As shown in FIGS. 17 and 18, the pressing member 95 is provided with a substantially box-shaped plate housing 955 on the lower side, and two side plates 952 extending upward are provided on one side surface of the plate housing 955. It has been. In the plate housing 955, the lever portion of the lever member described above is mounted. A plate bent in an L shape when viewed from the front is provided at the upper end of one side of the plate side plate 952. The L-shaped plate includes a vertical side plate 951 in the vertical direction and a horizontal plate 956 in the horizontal direction.
The bottom plate 955-1 on the lower surface of the plate housing 955 functions as a lid for pressing the supply tape supplied to the tape chute 2S from above. Further, the bottom plate 955-1 is provided with an opening 962 (see FIG. 18) through which the bearing 904 can be taken in and out, and a fixing portion 959 to which the other end of the spring 93 is attached. The space between the tape chute 2S and the bottom plate 955-1 functioning as a lid has a space where the supply tape 60 or 60 ′ can be sufficiently moved by the rotational drive of the first to third sprockets.

  The side plate 955-2 of the plate housing 955 has pins 967 and 968 protruding on both side surfaces in order to fix the presser member 95 to the feeder body by being fitted in a groove provided on a corresponding side surface of the feeder body. Provided in pairs. Further, a rotation shaft 905 for rotating the lever portion 91 by a predetermined angle with respect to the plate housing 955 fixed to the feeder body is attached to the hole 958 provided in a pair on the side plate 955-2.

A spring 93 is attached to the spring fixing portion 959 on the lower surface portion of the plate housing 955 and the spring fixing portion 909 of the lever member 91. The spring 93 pushes down the bearing 904 of the lever member 91 downward to lower the supply tape 60 downward from the opening 962, and pushes the supply tape 60 directly below the teeth 32h0 of the third sprocket 32 and the sprocket hole 64 of the supply tape 60. Are always fitted (during loading operation). For this reason, the spring 93 is a compression spring (see FIG. 5B).
Note that FIG. 17 shows a state in which the bearing 904 of the lever portion 91 is lifted upward and the supply tape 60 directly below it is not pressed in a state where the spring 93 is compressed, not during the above-described loading operation.

  A rotation shaft 961 is attached between the upper end of the plate side plate 952 and the plate housing 955, and a roller 953 is provided on the rotation shaft 961. The roller 953 is provided on the shaft 961 so as to freely rotate in the direction of the arrow 969 (both directions). A flange 954 is attached to the roller 953, and the supply tape 60 'is sandwiched between the plate side plate 953. For this reason, the supply tape 60 placed on the supply tape guide roller 953 does not shift in the lateral direction (does not come off).

The vertical vertical side plate 951 at the top of the plate side plate 952 is used as a handle when an operator removes the suppressor 90 from the feeder body. FIG. 24 is a view for explaining an embodiment of a system stop structure with the feeder body of the suppressor of the present invention.
In FIG. 24, when an operator pulls the vertical side plate 951 in the reverse direction (right direction in the drawing), the pins 967 and 968 are inclined along the grooves 295 of the main body side plate 29 extending on both side surfaces of the feeder main body described above. The suppressor 90 can be removed by moving upward and passing through the upper opening of the groove 295. Also, contrary to when the suppressor 90 is removed, the operator inserts pins 967 and 968 from the upper opening of the groove 295 of the main body side plate 29, moves obliquely downward (to the left in the drawing) using the groove 295 as a guide, The suppressor can be attached by moving to the left end of the groove 295 of the side plate 29. Thus, the suppressor of the present invention is detachably provided.

18, the worker holds the vertical plate 951 and the lever portion 901 with two fingers (for example, the thumb and the index finger) to bring the horizontal plates 906 and 956 into contact with each other, and the suppressor 90 is described later. It is used when changing from the state of FIG. 20 to the state of FIG. The lever portion 901 has a shape in which a flat plate is folded back in an inverted U shape so that an operator can easily operate and is not injured.
For example, the lever portion 901 and the horizontal plate 906 are referred to as a lever movable portion 91-1, and the lever movable portion 91-1 is formed by folding a single plate. Similarly, the vertical side plate 951 and the horizontal plate 956 are referred to as a lever fixing portion 95-1, and the lever fixing portion 95-1 is formed by folding a single plate.
As a result of the operator operating the lever portion 901 and the vertical side plate 951, the bearing 904 of the lever member 91 is lifted upward in a state where the spring 93 is compressed, and the supply tape 60 directly below it is not pressed. As a result, the engagement between the teeth 32h0 of the third sprocket 32 of the feeder 2 and the sprocket holes 64 of the supply tape 60 is released. When the operator removes his / her finger from the lever portion 901, the spring 93 is activated when the worker disappears from the spring force point. As a result, the force applied to the force point from the spring 93 pushes down the bearing 904 of the lever member 91 downward, and the supply tape 60 directly below the tooth 32h0 of the third sprocket 32 and the sprocket hole 64 of the supply tape 60 is always ( Returns to the mating state (during loading operation).
Further, an operator sandwiches the vertical side plate 951 and the lever portion 901 with two fingers, and closes the interval to a predetermined distance, and at the same time, the interval becomes zero, and at the same time, the upper surface of the horizontal plate 956 of the presser member 95 It is provided so that the lower surface of the horizontal plate 906 contacts.

Next, the tape loading suppressor mechanism of the feeder of the electronic component mounting apparatus of the present invention will be further described with reference to FIGS. This tape loading suppressor mechanism is a mechanism for releasing the engagement between the teeth 32 h of the third sprocket 32 and the supply tape 60 by the vertical movement of the bearing 904 of the tape loading suppressor (tape holding plate) of the feeder 2.
FIG. 20 is a view for explaining the state (see FIG. 4) during the loading operation of the suppressor 90 attached on the feeder. FIG. 21 is a view for explaining a state (see FIG. 11) during the unloading operation of the suppressor 90 mounted on the feeder. Furthermore, FIG. 22 is a diagram for explaining a state during another loading operation of the suppressor 90 attached on the feeder (see FIGS. 14A, 14B, and 14C).

In the normal state, as shown in FIG. 20, the spring 93 pushes the lever member 91 upward. For this reason, the bearing 904 of the lever member 91 is pushed downward with the rotating shaft 905 of the lever member 91 attached to the hole 958 of the presser member 95 as a fulcrum, and protrudes downward from the opening 962 of the presser member 95. That is, the spring 93 pushes up the force point of the lever member 91 and pushes down the bearing 904 at the action point of the lever member 91 with the rotating shaft 905 as a fulcrum.
The bearing 904 protruding downward pushes the supply tape 60 on the tape chute 2S downward. Then, the sprocket hole 64 of the supply tape 60 pushed downward is engaged with the tooth 32 h 0 of the third sprocket 32. The supply tape 60 is always kept downward by the force protruding downward from the bearing 904. Therefore, even if the third sprocket 32 rotates in the forward direction, the sprocket hole 64 and the teeth 32h0 are always meshed, and the sprocket hole 64 is in teeth. It will not deviate from 32h0. This is the same even if the third sprocket rotates in the reverse direction. The forward direction is the downstream direction and is the direction in which the supply tape 60 moves in the direction of arrow A, and the reverse direction is the upstream direction and the direction in which the supply tape 60 moves in the direction of arrow B.
Since the spring 93 always applies an upward force as a force point, the bearing 904 always protrudes downward when the suppressor 90 is attached to the feeder 2, and the sprocket hole 64 of the supply tape 60 and the third sprocket are provided. The 32 teeth 32h0 are always fitted.

Further, as shown in FIG. 21, it is assumed that the spring 93 is pushed by applying some force to the lever member 91 of the suppressor 90. FIG. 21 shows a state where the spring 93 is pushed and the bearing 904 is pushed upward and is housed in the presser member 95. That is, the meshing between the teeth 32h of the third sprocket 32 and the supply tape 60 is released.
FIG. 21 shows that when the lower surface of the horizontal plate 906 of the lever member 91 and the upper surface of the horizontal plate 956 of the pressing member 95 are in contact with each other, the bearing 904 is pushed up to the uppermost position and stored in the pressing member 95. ing. Of course, the state in which the bearing 904 is pushed upward and the sprocket hole 64 is disengaged from the teeth 32h0 is established when the lower surface of the horizontal plate 906 and the upper surface of the horizontal plate 956 approach each other by a predetermined distance.

Next, the operation of the feeder 2 due to the difference in the state of the suppressor 90 will be described with reference to FIG.
The operation described here is an operation of setting a new supply tape 60 ′ in advance at an arbitrary timing after the supply tape 60 is set in the feeder 2. This operation is performed by the operator operating the feeder 2.

  The state of the suppressor 90 in FIGS. 22A and 22B is the state described with reference to FIG. 20 (that is, the teeth 32h of the third sprocket 32 and the supply tape 60 are in mesh). 22A is the same as the embodiment in which the suppressor 90 is used instead of the suppressor 38 of the feeder 2 described in FIG. 4, FIG. 8A, FIG. 8B, or FIG. Even in this case, the operation of FIG. 22A is not different from the operation of the feeder 2 described in the first to third embodiments with reference to FIG. 4, FIG. 8A, FIG. 8B, or FIG.

Next, in FIG. 22A, the operator holds the lever portion 901 and the vertical side plate 951 with two fingers, and the horizontal plates 906 and 956 are brought into contact with each other to obtain the state shown in FIG. That is, since the vertical side plate 951 is fixed, the lever portion 901 rotates in the direction of the arrow H around the rotation shaft 905. In order to maintain the state shown in FIG. 21, it is necessary for an operator to keep the horizontal plates 906 and 956 in contact with each other, for example, by sandwiching the lever portion 901 and the vertical side plate 951 with two fingers.
In this state, when the operator lifts the suppressor 90 obliquely upward, the pins 967 and 968 move along the groove 295, the suppressor 90 is removed from the chute 2S, that is, the feeder body, and the supply tape 60 is lifted in this state. Then, the suppressor 90 is attached again. The suppressor 90 can be removed without holding the lever portion 901 and the vertical side plate 951 with two fingers and bringing the horizontal plates 906 and 956 into contact with each other.

FIG. 22B shows the case where the operator removes the finger from the lever portion 901 and the vertical side plate 951 after taking out the supply tape 60. As a result, the force of the spring 93 works, and the bearing 904 is lowered below the plate housing 955 of the pressing member 95.
The worker sets the middle portion of the raised supply tape 60 on the roller 953 of the suppressor 90. The roller 953 is for smoothly feeding the set supply tape 60 in the forward direction or the reverse direction without resistance. As a result, even when the electronic component mounting apparatus 1 is mounting a component, the tape 95 can be smoothly fed without resistance by the action of the roller 953.

Next, the operator prepares a new supply tape 60 ′, and inserts the tip end portion 60 a from the tape insertion opening C onto the third sprocket 32 to a position where the sprocket hole 64 and the sprocket teeth 32 h 0 are fitted. FIG. 22D shows this state.
The operator inserts the tip 60a to a position where the sprocket hole 64 and the sprocket tooth 32h0 are fitted. When inserting the tape, the operator rotates the lever part 901 by holding the vertical side plate 951 and the lever part 901 with two fingers to move the bearing 904 away from the third sprocket 32, and the tooth 32h of the third sprocket 32 This is performed while releasing the engagement with the supply tape 60.
In this state, the parts supply operation of the feeder 2 is finished.
Since the lever portion 901 is located above the supply tape 60 placed on the roller 953, the tape 60 can be operated without obstructing the worker, and the bearing 904 is separated from the third sprocket 32. Can do. Note that the height of the supply tape 60 is slightly lower than the portion in contact with the roller 953 at a position directly below the lever portion 901.
The lever joint 902 is thin in the direction perpendicular to the tape running direction and swings at a position that does not interfere with the running of the tape 60 aligned with the plate side plate 952.

Thereafter, when it is detected that the electronic component mounting apparatus 1 continues to operate and there are no more electronic components stored in the supply tape 60 that has run out, the following operations (1) and (2) are performed. To continue the component mounting operation. That is, when the tape insertion detection sensor 31 detects the passage of the end portion 60 ″ of the supply tape 60 and recognizes the occurrence of a continuous suction abnormality due to no parts, the control device 80 supplies the supply tape 60 in use. It is determined that all the electronic parts have been used up, and the subsequent operations are performed.
(1) Forced feeding operation of supply tape 60 in use (2) Automatic loading operation of next supply tape 60 ′ The operation of FIG. 22 (d) is performed using FIG. 14A, FIG. 14B, FIG. 14C, or FIG. The operation of the feeder 2 described in the third embodiment is not different at all.

In the suppressor 90 described in the fourth embodiment, the vertical side plate 951 and the lever portion 901 are provided at a position higher than the supply tape 60 set on the roller 953, as shown in FIG. 22B or 22C. .
The reason for this is that when a new tape 60 ′ is inserted, if there is a vertical side plate 951 and a lever portion 901 below the supply tape 60, the supply tape 60 gets in the way and the operator's two fingers do not enter and cannot be operated. It is. Also, as shown in FIGS. 1 and 2, a plurality of feeders are set adjacent to each other in a feeder cart 50. For this reason, even if it tries to operate the suppressor of the target feeder from the side or the diagonal direction, it cannot be operated.
Therefore, the suppressor 90 according to the fourth embodiment is provided at a position higher than the supply tape 60 set (mounted) on the roller 953.
Note that the number of rollers need not be one, and a plurality of rollers may be provided.
Further, the suppressor 90 is made of SUS material except that the roller 953 is made of hard plastic, but may be other materials or a composite of these materials.

  In the above-described fourth embodiment, the operation lever fixing portion 95-1 and the lever movable portion 91-1 are provided at a position higher than the roller 953 where the electronic component 4 guides the first supply tape 60. As a result, according to the fourth embodiment, the second supply tape to be added to the feeder by the operator operating the lever fixing portion and the lever movable portion can be easily, quickly and safely inserted with high reliability. Can do. Therefore, in addition to the effects of the first to third embodiments, since the operation of the suppressor is simplified, the worker can perform the tape supply operation safely, quickly, and easily.

Hereinafter, Example 4 of the present invention will be described with reference to FIG. FIG. 23 is a view for explaining another embodiment of the lever portion of the suppressor.
FIG. 23A illustrates the pressing member 91 of the suppressor 90 described in the fourth embodiment. As already described, the lever portion 901 has a shape in which a flat plate is folded back in an inverted U shape as shown in a broken-line circle 910 in FIG. However, the shape may be any shape that allows the operator to perform the operation of sandwiching the vertical side plate 951 and the lever portion in the direction of the arrow H. For example, as shown in FIGS. 23B to 23D, (b) a vertical plate shape, (c) a vertical inverted U shape, (d) a shape in which the lever 901 is vertical, and the like are free. Further, instead of the pinching operation, the horizontal plate 906 of the lever member 91 may be pushed from above by the worker as shown in FIG. 23 (e) or (f) (arrow V direction). Furthermore, as shown in FIG. 23 (g), both a sandwiching structure and a pushing structure may be provided so that an operator can select an operation method. 23 (f) and 23 (g) may be pushed, and in the case of FIGS. 23 (a) to 23 (e), the horizontal plate 906 may be simply pushed.

  According to the fifth embodiment, the same effects as those of the fourth embodiment can be obtained, and design diversity and design freedom are increased.

According to the first to fifth embodiments, the supply tape for subsequent replenishment is not physically connected. That is, no splicing tape for connection is required.
In addition, the next supply tape can be set in the replenishment unit at any time regardless of whether or not the remaining supply tape is in use.
In addition, it is not necessary to monitor the replenishment timing severely, and it is possible to reduce the worker's restraint time.
In addition, since the splicing tape as a consumable is not necessary, the running cost can be reduced. That is, material costs can be reduced.
In addition, parts can be replenished to the lane where the parts have run out (set of supply tape) without loading the feeder.
In addition, the effect of splicing passage rate (occurrence of choke stop (fluctuation of device operation rate) due to clogging), which has been affected by the skill of the worker, is eliminated, and the reliability is improved by the automatic loading operation.
In addition, by carrying out the cutting position of the tape tip at a predetermined position, even with a supply tape with a different feed pitch, it is possible to automatically cue the pocket position to a predetermined suction position. There is no need to check the feed position after loading the tape.
Furthermore, since the electronic component mounting apparatus is compatible with ACV, an automatic loading operation can be prohibited for a component that has not been verified. The subsequent supply parts can be collated and the automatic loading operation can be prohibited, as in the conventional splicing subsequent tape.
