Carrier tape walking device and electronic component handling device

The present invention relates to a tape running technique that can be used interchangeably for the purpose of accommodating an electronic component in a carrier tape and for removing the electronic component from the carrier tape.

Electronic components are classified as good or defective after various inspections in the manufacturing process, and are shipped after being bundled. If the inspection standard is severe, the misjudgment rate of classifying the electronic components that are good products into the containment body of the defective product will increase, and the production efficiency will be lowered. If the inspection standard is loose, the electronic components belonging to the defective product are shipped as good products, resulting in different quality, which leads to a decrease in the reliability of the inspection. In an electronic component of an integrated circuit such as an IC or a LSI having a high unit price, a high false positive rate and a different quality are serious problems.

Therefore, in the steps of inspection and classification, it is sometimes necessary to include whether a defective product is included in the good product group, or whether the defective product group contains a good product, or change the inspection item, inspection method, or inspection accuracy. Check, then reflect the re-inspection results, reclassify the good product group or the defective product group, and then bundle the product and ship it.

An electronic component conveying device that inspects, sorts, re-inspects, and reclassifies an electronic component is configured as a system including a plurality of tape wrapping devices and one tape stripping device. This electronic component conveying device is a plurality of wrapping devices prepared by placing electronic components on a conveyance path for inspection and classifying the electronic components to a level corresponding to the quality. When the classification of the electronic component is completed, the reel after the level of the re-inspection is transferred from the tape wrapping device to the tape stripping device, and the electronic component is placed on the conveyance path again for re-inspection, and the electronic components are classified into A plurality of strap devices prepared in response to the quality level.

The wrapping device is a device that causes the carrier tape to travel intermittently toward the reel for winding the carrier tape (for example, refer to Patent Document 1). In the carrier tape, the bag portion is embossed along the length direction. The robot or the like sends the electronic component into the pocket while the strap device stops the carrier tape. In the carrier tape device, the sealing tape is superposed and pressure-bonded to the carrier tape, thereby sealing the electronic components housed in the bag portion.

The stripping device is a device that intermittently travels while pulling the carrier tape out of the reel (see, for example, Patent Document 2). The robot or the like takes out the electronic component from the pocket portion while the tape stripping device stops the carrier tape. The stripping device inserts a claw between the carrier tape and the sealing tape to peel the sealing tape from the carrier tape and expose the electronic component.

In addition, the carrier tape running device 1 is a tape stripping device, and the sealing portion 2 is retracted from the traveling path of the carrier tape 100, and the carrier tape 100 is pulled out from the reel 200 side to perform reverse travel, and the sealing tape 102 is caused to be reversed. The sealing tape reel 3 is wound around the carrier tape reel 3 and peeled off from the carrier tape 100.

The carrier tape running device 1 includes two sprocket wheels 41 and 42. The two sprocket wheels 41 and 42 are discs having the same diameter as the projections 43 projecting along the circumferential surface. The sprockets 41 and 42 are connected to the output shafts of the corresponding motors 51 and 52 through the timing belts 51a and 52a, respectively, and intermittently rotate in the same circumferential direction, the same amount of rotation, and the same timing.

The carrier tape 100 is wound around the two sprockets 41, 42. The carrier tape 100 is provided with sprocket holes at equal intervals along the longitudinal direction on the tape side. The projections 43 of the two sprockets 41, 42 are engaged with the sprocket holes. The sprockets 41 and 42 are such that the projections 43 are engaged with the sprocket holes for rotation, and the carrier tape 100 is moved in the longitudinal direction. The projections 43 have a circular shape and are processed into an involute shape. The diameter of the protrusion 43 is slightly smaller than that of the carrier tape 100 Sprocket hole.

The two sprockets 41, 42 are arranged on the same vertical plane, and their axes of rotation are parallel and the height is the same. Therefore, the carrier tape 100 travels toward the reel 200 side or away from the reel 200 while maintaining the extending direction horizontal.

The rotational pitch of the motors 51, 52 corresponds to the arrangement interval of the pockets 101. The carrier tape 100 has the embossed bag portion 101 at equal intervals in the longitudinal direction. That is, the motors 51, 52 stop the bag portion 100 at a common stop position. One of the common stop positions is set at the delivery position 6 of the electronic component 104.

The holding means 311 of the adsorption nozzle or the like is present vertically above the delivery position 6. In the carrier tape running device 1, the bag portion 101 is sequentially placed at the delivery position 6 as a wrapping device, and the electronic component 104 of the detachment holding means 311 is housed in the carrier tape 100 or as a tape stripping device. The electronic component 104 in 101 is taken out by the holding means 311.

The motor driver 7 may be provided in the carrier tape running device 1 or may be provided on the control device side for integrally controlling the holding means 311 and the like.

The sealing portion 2 is provided with a heater as shown in Fig. 1 Block 21 and base block 22. The heater block 21 and the base block 22 are opposed to each other via the traveling path of the carrier tape 100. The heater block 21 presses the carrier tape 100 from above the traveling path of the carrier tape 100, and the base block 22 presses the carrier tape 100 from below the traveling path of the carrier tape 100. As shown in Figs. 1 and 2, the heater block 21 is movable in contact with or away from the traveling path of the carrier tape 100.

In the sealing portion 2, the sealing tape 102 is superposed on the carrier tape 100 and supplied. The heater block 21 and the base block 22 are crimped by the carrier tape 100 by the clamping, and the heater block 21 further supplies heat to the sealing tape 102 and the carrier tape 100. surface.

When the tape reel 3 is used as a tape wrapping device, the sealing tape 102 is pulled toward the carrier tape 100. When the tape is taken as a tape stripping device, the sealing tape 102 is wound in a direction away from the carrier tape 100. The sealing tape reel 3 is provided with a motor 31 and a pressure roller 32 which are positioned above the traveling path of the carrier tape 100.

The motor 31 rotates the seal reel 3 through the timing belt, and the seal reel 3 can be rotated forward and reversed, for example, a servo motor having an H-bridge circuit. The pressure roller 32 is positioned near the travel path of the carrier tape 100 for guiding the sealing tape 102 to the carrier tape 100.

As shown in Figs. 1 and 2, the pressure roller 32 is movable toward or away from the traveling path of the carrier tape 100. When the carrier tape running device 1 functions as a tape wrapping device, as shown in Fig. 1, the traveling path of the carrier tape 100 is approached, and the sealing tape 102 is pressed against the carrier tape 100. When the carrier tape running device 1 functions as a stripping tape, as shown in Fig. 2 Generally, it leaves the walking route of the carrier tape 100. By separating the pressure roller 32 from the traveling path of the carrier tape 100, the angle θ formed between the carrier tape 100 and the sealing tape 102 at the peeling base point 9 of the carrier tape 100 and the sealing tape 102 is gentle.

Further, as shown in FIG. 1, the carrier tape running device 1 that causes the carrier tape 100 to travel in two directions is provided with a suction portion 8 below the traveling path of the carrier tape 100. The carrier tape 100 has a hole portion on the bottom surface of each pocket portion 101. The suction portion 8 sucks the electronic component 104 inside the pocket portion 101 through the hole portion and bonds it to the bottom surface of the pocket portion 101.

As shown in FIG. 3, the suction portion 8 is provided with a container 81 having a suction groove 82 on the side of the traveling path of the carrier tape 100, and a plurality of suction holes 83 are formed in the bottom of the container 81. The suction groove 82 is opened along the traveling route directly below the traveling path of the carrier tape 100. The groove width of the suction groove 82 is equal to or larger than the diameter of the hole portion of the bag portion 101 opened in the carrier tape 100, and is smaller than the bandwidth of the carrier tape 100. The suction hole 83 communicates with an air pressure circuit of a vacuum generating device such as a vacuum pump.

The suction portion 8 decompresses the inside of the container 81 by the suction hole 83, and the electronic component 104 in the pocket portion 101 is attached to the bag by the suction groove 82 and the hole portion formed in the pocket portion 101 of the carrier tape 100. The bottom surface of the portion 101.

(action)

The entrainment operation of the carrier tape running device 1 is as follows. The carrier tape running device 1 is such that the timing belts 51a, 52a are rotated by the forward rotation of the motors 51, 52. Walking, the sprocket 41, 42 is rotated forward. The sprockets 41, 42 are such that the projections 43 are caught in the sprocket holes, and the carrier tape 100 is moved toward the reel 200 side.

In the carrier tape running device 1, the carrier tapes 100 are intermittently rotated to the reel 200 side by intermittently rotating the motors 51 and 52, and the empty bag portions 101 are sequentially placed at the delivery position 6. Each of the holding means 311 stops the electronic component 104 one by one and sequentially stops at the delivery position 6, and accommodates the electronic component 104 in the pocket portion 101 which is present at the delivery position 6.

The sealing tape reel 3 pulls the sealing tape 102 toward the carrier tape 100 side by the forward rotation of the motor 31. The pressure roller 32 guides the sealing tape 102 pulled out from the sealing tape reel 3 to the surface of the carrier tape 100 so that the sealing tape 102 overlaps the surface of the carrier tape 100 on which the bag portion 101 is opened.

In the sealing portion 2, the heater block 21 is brought into contact with the traveling path of the carrier tape 100 in advance. In the sealing portion 2, the sealing tape 102 is superposed on the carrier tape 100 and supplied. In the sealing portion 2, the carrier tape 100 and the sealing tape 102 are sandwiched between the heater block 21 and the base block 22, and the sealing tape 102 is bonded to the carrier tape 100 by pressurization and heating. Thereby, the electronic component 104 in the pocket part 101 is sealed by the sealing tape 102 and the inner wall of the pocket part 104.

The carrier tape 100 is guided to the reel 200 by further intermittent walking after being sealed by the sealing tape 102, and wound around the reel 200.

The stripping operation of the tape running device 1 is as follows. In the carrier tape running device 1, the timing belts 51a and 52a are moved by the intermittent reversal of the motors 51 and 52, and the sprockets 41 and 42 are reversed. The sprocket 41, 42 causes the protrusion 43 to be caught in the sprocket hole, and the carrier tape 100 is taken from the reel 200 is pulled out intermittently.

Here, the projections 43 are rounded and have an involute shape. The involute shape is generally made to facilitate the rotation of the gear by bringing the teeth of the gear into contact with each other at a certain angle and a certain area and forming an appropriate clearance. When the involute shape is applied to the projections 43, the vibration accompanying the travel of the carrier tape 100 is suppressed, and the stability of walking is increased.

Further, the transmission mechanism between the motors 51, 52 and the sprocket wheels 41, 42 is changed from the normal ratchet to the timing belts 51a, 52a on the stripping device, so that the vibration accompanying the travel of the carrier tape 100 is suppressed. And increase the stability of walking.

On the other hand, the sealing tape reel 3 winds the sealing tape 102 at the same speed, the same amount, and the same timing as the reverse travel of the carrier tape 100. The carrier tape 100 is reversely traveling horizontally, and the sealing tape 102 is wound above the traveling path of the carrier tape 100. Therefore, the carrier tape 100 and the sealing tape 102 are branched in different directions to peel the sealing tape 102 from the carrier tape 100.

At this time, in the stripping operation, the sealing portion 2 retracts the heater block 21 upward, and forms a space in which the carrier tape 100 is separated from the sealing tape 102 from a position close to the reel 200. Further, the sealing tape reel 3 moves the pressure roller 32 upward during the stripping operation. Thereby, the carrier tape 100 and the sealing tape 102 are peeled off at a gentle angle θ.

Since the adhesion area between the carrier tape 100 and the sealing tape 102 in the opening region of the pocket portion 101 is small, the force required for peeling off in this region is higher. Small, if a certain amount of force is applied during peeling, it can be peeled off in this area in one go. Further, if the opening area of the bag portion 101 is exceeded, a relatively large force is required at the time of peeling, and the progress of peeling is reduced. Therefore, in the carrier tape 100, a large vibration is generated in the stripping operation.

However, in the carrier tape running device 1, since the carrier tape 100 and the sealing tape 102 are peeled off at a gentle angle θ, the progress of peeling in the opening region of the bag portion 101 is moderated, and the tape carrier during the stripping operation is carried out. The vibration of 100 is weakened, and the reverse travel of the carrier tape 100 is stabilized.

Further, the carrier tape running device 1 drives the suction portion 8 during the stripping operation. The suction portion 8 decompresses the container 81 through the suction hole 83, and sucks the electronic component 104 in the pocket portion 101 by the suction groove 82 and the hole of the pocket portion 101. Therefore, in the intermittent reverse running of the carrier tape 100, the electronic component 104 is adsorbed to the carrier tape 100 and integrated, and the rocking in the pocket portion 101 of the electronic component 104 is suppressed, and the travel of the carrier tape 100 is stabilized. Further, the suction portion 8 acts to adsorb the carrier tape 100, and the vibration generated on the carrier tape 100 is relieved when the sealing tape 102 is peeled off.

Next, the bag portion 101 exposed by the peeling of the sealing tape 102 from the carrier tape 100 is sequentially placed at the delivery position 6 by the intermittent reversal of the motors 51 and 52. The empty holding means 311 are sequentially stopped at the delivery position 6, and the electronic component 104 existing at the delivery position 6 is taken out.

The wafer ring holder 320 moves the wafer ring 103 in parallel so that the electronic components 104 are sequentially moved toward the pickup position, and are pushed up toward the pickup device 330 by the ejector pins 321. The pickup device 330 picks up the electronic component 104 at the pickup position by the arm 331 and delivers it to the holding means 311 of the transfer table 310. Wafer ring holder 320 and pick-up device 330, The movement toward the pickup position of the electronic component 104, the pickup of the electronic component 104 at the pickup position, and the transfer to the holding means 311 are repeated.

The conveyance table 310 is intermittently rotated by the direct drive motor 312, and the holding means 311 moves on the conveyance path 301 while holding the electronic component 104. When the holding means 311 passes through each of the observation devices 340, each of the observation devices 340 performs observation processing of the electronic component 104. For example, when the observation device 340 is provided with a position correction device, a camera, and an electrical characteristic measurement device, the electronic component is subjected to position correction for inspection by the position correction device, and is performed by a camera and an electrical characteristic measurement device.

In the carrier tape running device 1 for the good product, the electronic component 104 is housed in the bag portion 101 of the carrier tape 100 while the carrier tape 100 is traveling in the direction of the reel 200, and is sealed by the sealing tape 102. The reel 200 is wound by a carrier tape 100 sealed by a sealing tape 102.

If the electronic component 104 classified into a grade other than the good product arrives at the carrier tape running device 1 other than the good product, the electronic component is being held. The holding means 311 of 104 disengages the electronic component 104.

The carrier tape running device 1 for use outside the good product is attached to the sealing portion 2 and functions as a tape wrapping device. In the carrier tape running device 1 for the good product, the electronic component 104 is housed in the bag portion 101 of the carrier tape 100 at the delivery position 6 while the carrier tape 100 is traveling in the direction of the reel 200, and is sealed by the sealing tape 102. The reel 200 is wound by a carrier tape 100 sealed by a sealing tape 102.

When the electronic components 104 of the wafer ring 103 are classified into good products or good products and the packaging for the carrier tape 100 is completed, the electronic components 104 classified as good products are re-examined. During the re-inspection, the operator confirms the data obtained by the observation device 340, and re-determines the electronic component 104 classified as a good product as a good product or a good product.

After the determination, the carrier tape running device 1 for use outside the good product removes the sealing portion 2 and attaches the peeling portion 3 to become a tape stripping device. Next, the electronic component conveying device 300 is a re-sorting mode, and the carrier tape running device 1 other than the good product is used as a tape stripping device, and the carrier tape 100 is withdrawn from the reel 200, and the sealing tape 102 is peeled off from the carrier tape 100.

The holding means 311 releases the electronic component 104 by exposure to the atmosphere or breaks the vacuum, and the electronic component 104 is transferred to the wafer ring 103.

The holding means 311 for holding the electronic component 104 which is determined to be a good product is intermittently rotated by the transfer table 310 to reach the carrier running device 1 for the good product in which the sealing portion 2 is still attached, by exposure to the atmosphere or destruction. The vacuum is applied to release the adsorption of the electronic component 104, and the electronic component 104 is detached from the pocket portion 101 of the delivery position 6.

In the carrier tape running device 1 for good use, the electronic component 104 is housed in the bag portion 101 of the carrier tape 100 at the delivery position 6, and is sealed by the sealing tape 102. The reel 200 is wound by a carrier tape 100 sealed by a sealing tape 102.

Thereby, the electronic component 104 is sorted from the wafer ring 103 to the carrier tape running device 1 for good products and the carrier tape running device 1 other than the good product. Then, the electronic component 104 that has been classified as the carrier tape 100 other than the good product is re-determined, and the carrier tape running device 1 that is the tape wrapping device and the electronic component 104 other than the good product is stored as a tape stripping device. The supply is then further classified into a tape carrier device 1 for use as a good product for the tape wrapping device and a wafer ring holder 320 for use outside the product.

In the carrier tape running device 1, the sealing tape 102 is pulled out from the sealing tape reel 3 by the forward rotation of the motors 51 and 52, and the pair of blocks 21 and 22 are brought close to each other, thereby sealing the carrier tape 100. The belt 102 is sealed with a tape wrapping device. Further, by reversing the motors 51 and 52, the sealing tape 102 is pulled toward the sealing tape reel 3, and the pair of blocks 21 and 22 are separated to become a stripping device for peeling the sealing tape 102 from the carrier tape 100. .

Thereby, the carrier tape running device 1 can be used as both a tape wrapping device and a tape stripping device. Therefore, it is not necessary to separately prepare the strapping device and the stripping device, and the cost of the device can be reduced. For example, it is not necessary to provide a dedicated stripping device for the electronic component handling device 300. Further, the area occupied by the electronic component conveying device 300 is reduced by the portion where the stripping device is not provided, and the production efficiency of the electronic component per unit area is improved.

As the electronic component conveying device 300, a container holding means, an observation device 340, and a plurality of carrier tape running devices 1 are provided around the transfer table 310 for forming the conveyance path 301. The holding means is for holding the housing of the electronic component 104; the viewing device 340 is for viewing the electronic component 104 in the transport path 301. The container holding means is, for example, a wafer ring holder 320 which is a wafer ring 103.
