Description

Bar code recognition device for sorting machine for electronic parts processing

The present invention relates to a barcode recognition device applied to a sorting machine for processing electronic components to recognize barcodes printed or attached to electronic components.

Currently, information on electronic components is managed in the sorter in Lot (LOT) units.

In most cases, in order to prevent batches of different quantities from being mixed, the sorter is run once based on the quantity of a batch. However, large-scale electronic components such as random access memory (RAM) modules loaded with dozens of electronic components are specially manufactured for the final production product, so the quantity of one batch is small. Therefore, in order to process the quantity of a plurality of batches, the sorter needs to be operated many times, which reduces the operation rate of the sorter.

Therefore, recently, the history (production plant or production line, lot information, etc.) and test results of the corresponding electronic components tend to be independently managed by recognizing the barcodes of the electronic components. To this end, the sorting machine is correspondingly equipped with a barcode recognition machine that can recognize barcodes. In this case, the sorting machine is equipped with a barcode recognition machine to be able to recognize the barcode located on a specific side of the electronic part, and the barcode recognition machine is arranged on the moving path of the electronic part in consideration of the efficiency of the operation.

However, in the case of an electronic component that is specialized for the final production product, it cannot be ruled out that the position of the barcode is on the reverse side. In this case, only additional sorting machines capable of recognizing barcodes located on the reverse side can be used. This is a cost burden for the customer of the sorter, and it is not preferable in terms of space utilization. Also, even if such a sorter can handle the quantity of a plurality of batches, batches whose barcode positions are located on different faces cannot be processed by running the sorter once, so the operation rate will decrease accordingly.

Therefore, the applicant of the present invention has proposed a bar code by Korean Laid-Open Patent Publication No. 10-2017-0108703 (hereinafter referred to as "Prior Art 1") and Korean Application No. 10-2017-0040270 (hereinafter referred to as "Prior Art 2"). A technology in which barcodes on both sides of an electronic component can be selectively read by an identification machine.

Typically, within the sorter, the movement of the electronic components is done by means of a pick-up device or moved by means of a mobile shuttle. The prior art 1 shows an example of reading the barcode of an electronic component in a state picked up by a pickup device, and the prior art 2 shows an example of reading the barcode of an electronic component mounted on a moving shuttle.

In the prior art 1, the number of barcode sorting machines twice as many as the number of electronic components picked up by the pickup device is provided, so that all barcodes that may be selectively located on both sides of the electronic components can be selectively read. In this case, the spacing between the electronic components picked up by the pickup device must be sufficiently large, and therefore it is necessary to sufficiently secure the spacing between the individual pickups constituting the pickup device. Also, due to this, it is necessary to enlarge the overall size of the pickup device, or to provide an additional drive unit for adjusting the spacing between the individual pickups, and to ensure the space occupancy rate of the pickup device in the equipment. In this case, due to the size of the pickup device, the design is complicated to solve the interference problem of the moving path, etc., or the enlargement of the device itself, the installation of the drive unit, and the increase in the number of barcode readers. rising production costs. Of course, although the prior art 1 also proposes an example in which the distance between independent pickups can be minimized by using mirrors, it still has limitations in reducing the size of the pickup device, so it still has the problem of increasing the number of cameras. increased pressure on production costs.

In addition, in the prior art 2, by rotating the barcode reader by a predetermined angle, it is possible to selectively read all barcodes which may be selectively located on both sides of the electronic component. According to the prior art 2, since the recognition direction of the barcode reader has an inclination, the reading rate will be reduced, so an expensive barcode reader is also required, and in order to avoid the sticking position of the barcode (the barcode is attached to the upper side) or lower side) to be able to read all of the impact ground, it is necessary to ensure sufficient spacing between electronic components. Therefore, there are quite a few problems as in the prior art 1.

An object of the present invention is to provide a technology related to a barcode recognition device that can improve the recognition rate by further improving the prior art 1 and the prior art 2 so as to minimize the expansion of equipment and the increase in production cost.

Furthermore, the object of the present invention is to provide a technology that can identify the barcodes regardless of which side the barcode is attached to (whether on the left, right or both sides) and even if the heights of the barcodes are different.

According to the first aspect of the present invention, a barcode recognition device for a sorting machine for processing electronic parts includes: one or more barcode recognition machines for recognizing barcodes on electronic parts moving along a predetermined moving path; and a rotating machine for making The barcode recognition machine is rotated 180 degrees in forward and reverse directions, so that the barcode recognition machine can recognize all or selectively the barcodes located on one side and the other side of the electronic component respectively.

The barcode recognition device of the sorting machine for processing electronic components further comprises: a rotary plate provided with the one or more barcode recognition machines and rotated by the rotary machines; and a base plate provided with the rotary machines, so that the The rotating plate and the base plate are spaced apart from each other.

The base plate is equipped with a clamping end, and the base plate is equipped with a stopper. When the rotating plate rotates, the clamping end will be clamped by the stopper, and the rotation degree of the rotating plate is set accordingly. .

The barcode recognition device of the sorting machine for processing electronic components may further include a correction machine for correcting the rotational positions of the one or more barcode recognition machines if the one or more barcode recognition machines are rotated by the rotating machine .

The barcode recognition device of the sorting machine for processing electronic components may further include: a height adjustment machine for adjusting the height of the one or more barcode recognition machines.

When the rotating machine rotates the one or more barcode readers, the position of the pickup device for moving the electronic components is moved so that the electronic components and the barcode readers correspond to each other.

A plurality of the barcode recognition machines are provided, and when the rotating machine rotates the plurality of the barcode recognition machines, the corresponding order of the plurality of the barcode recognition machines is changed.

When the rotary machine rotates the one or more barcode readers, the rotary machine may be rotated off-axis or moved horizontally so that the electronic components and the barcode readers correspond to each other.

According to the present invention, the enlargement of equipment and the increase in production cost can be minimized, and the barcode recognition rate can be improved.

Hereinafter, the preferred embodiments according to the present invention will be described with reference to the accompanying drawings, and for the sake of brevity of the description, the description of the repeated or substantially identical structures will be omitted or simplified as much as possible. < Description of the structure of the barcode recognition device >

1 is a partially exploded perspective view of a barcode recognition device 100 (hereinafter referred to as a “barcode recognition device”) of a sorting machine for processing electronic components according to the present invention.

The barcode recognition device 100 of FIG. 1 includes four barcode recognition machines 110 , a height adjustment machine 120 , a mirror 130 , a setting plate 140 , a rotating plate 150 , a rotating machine 160 , a base plate 170 and a correcting machine 180 .

The four barcode recognition machines 110 are equipped for respectively recognizing barcodes of the electronic components D that are moved along a predetermined movement path by the pickup device. Although the barcode recognition machine 110 is considered as a camera in this embodiment, it can also be equipped with a general barcode reader according to the implementation. With the barcode reader 110, it can be confirmed whether the electronic component D is inserted in the reverse direction, and if it is equipped with a camera, it can also confirm whether foreign matter is attached or whether the barcode is defective.

For reference, the bar code can contain various information such as production history, test history, etc. This information can be transmitted to the computer (PC) of the testing machine or sorting machine, so that the equipment required for sorting or testing electronic components D It can be used as a reference when controlling.

The height adjustment machine 120 is equipped for improving the barcode recognition rate by adjusting the equipped height of the barcode recognition machine 110 . In this embodiment, a long long hole is formed in the height adjustment machine 120 along the up-down direction, and the height of the barcode identification machine 110 can be adjusted manually by using the mounting bolt B, but as long as the structure can make the barcode identification machine 110 rise and fall, the Either can be preferably considered, and the use of a motor or the like for automatic adjustment can also be fully considered.

The mirror 130 is equipped for refracting light by 90 degrees to transmit the image of the barcode of the electronic component D to the barcode recognition machine 110 located under the lens barrel MT. That is, if the electronic component D is lowered by the pickup device, the portion with the barcode of the electronic component D picked up by the pickup device will be located at least between the mirrors 130 , and accordingly, the barcode reader 110 will read through the respective mirrors 130 . image of the barcode.

The purpose of providing the setting plate 140 is to mount the mirror 130 and the barcode reader 110 by supporting the lens barrel MT.

The purpose of providing the rotating plate 150 is to finally rotatably install the mirror 130 and the barcode reader 110 by supporting the setting plate 140 and the lens barrel MT. To this end, the setting plate 140 and the rotating plate 150 are integrated by being spaced apart by a predetermined height from the space maintaining rod GR. Therefore, if the rotating plate 150 rotates, the setting plate 140 will also rotate by the same angle, and the mirror 130 and the barcode reader 110 installed on the setting plate 140 will also rotate based on the rotation center point of the rotating plate 150 . By applying such a rotating plate 150, a structure in which a plurality of barcode readers 110 can be rotated together by one rotating machine 160 is realized.

Furthermore, as shown in the extracted view of FIG. 2 , in order to enable the rotation degree of the rotating plate 150 to be set to a rotation amount of 180 degrees, the rotating plate 150 is provided with two engaging ends 151 on both sides, and also has two Correction holes 152a, 152b for correcting the position. In this embodiment, the two snap ends 151 are provided by bearings, and the snap ends 151 and the alignment holes 152a and 152b will be described below.

The rotating machine 160 is provided to rotate the rotating plate 150 by 180 degrees. With the rotating machine 160, the rotating plate 150 and the barcode identification machine 110 finally installed on the rotating plate 150 can be rotated 180 degrees in the forward and reverse directions based on the rotation center point of the rotating plate 150. Accordingly, the barcode identification machine 110 can All the barcodes located on one side surface and the other side surface of the electronic component D can be recognized or selectively recognized. For this purpose, the rotary machine 160 includes a driving cylinder 161 , a rotary belt 162 , a coupling block 163 , a first pulley 164 a , a second pulley 164 b , a rotating member 165 , a reference member 166 , and an adjusting member 167 , as shown in the extracted view of FIG. 3 . and setting part 168 .

The driving cylinder 161 provides the driving force required to rotate the rotary plate 150 .

The rotating belt 162 transmits the linear driving force of the driving cylinder 161 as the rotational force of the first pulley 164a and the second pulley 164b.

The coupling block 163 couples the advancing and retracting rod FB of the driving cylinder 161 to the rotating belt 162 . Therefore, if the driving cylinder 161 is operated, the rotating belt 162 will rotate with the two pulleys 164a, 164b as rotation transition points.

The first pulley 164a and the second pulley 164b are provided in order to provide the rotating belt 162 . Such a first pulley 164a and a second pulley 164b provide a rotation transition point of the rotating belt 162 and rotate in conjunction with the rotation of the rotating belt 162 .

The rotating member 165 is coupled to the second pulley 164b so as to rotate together with the rotation of the second pulley 164b. Since the rotating plate 150 is coupled to the rotating member 165, the rotating plate 150 rotates in conjunction with the rotation of the rotating member 165. . Due to this structure, if the driving cylinder 161 operates, the rotating belt 162 will rotate with the two pulleys 164a and 164b as the rotation transition points, and at this time, the rotating member 165 will rotate in conjunction with the rotation of the second pulley 164b, and the rotating plate will also rotate. 150 will also spin along with it.

The purpose of providing the reference member 167 is to adjust the position of the setting member 168 in conjunction with the base plate 170 .

The adjustment part 167 is screwed together and passes through the reference part 166 with its distal end contacting the setting part 168 . Therefore, when the adjusting member 167 is rotated, the adjusting member 167 is moved by screwing or loosening the screw, and the position of the adjusting member 168 is adjusted while the setting member 168 is moved in conjunction with this.

The setting member 168 is provided for setting the first pulley 164a. Such a setting member 168 is movably coupled to the base plate 170 as in the excerpt of FIG. 4 . For this reason, the setting member 168 is formed with a long long hole LH in the moving direction, and the connecting bolt JB is coupled to the base plate 170 through the long hole LH, so that the setting member 168 can move somewhat. Furthermore, the setting member 168 can be guided and moved by the moving groove MG formed in the base plate 170 by the cutting machine.

As previously described, enabling the position of the setting member 168 to be changed is to maintain the tension of the rotating belt 162 . The tension of the rotating belt 162 may vary due to the weight of the bonded substance or sag due to use or the temperature of each season, etc. In this case, it is difficult to complete the precise rotation of the rotating plate 150 by rotating the belt 162 . Therefore, in the present embodiment, the tension of the rotating belt 162 is maintained at an appropriate level by moving the setting member 168 with the adjusting member 167, so that the rotating plate 150 can be rotated accurately.

For reference, in this embodiment, in order to reduce the production cost, the rotary plate 150 is rotated by the driving cylinder 161, but it may be simply realized by a forward and reverse rotation motor according to the implementation.

In addition, the rotary machine 160 is provided on the base plate 170 . Such a base plate 170 is provided with a stopper 171 capable of engaging with the engaging end 151 as described with reference to FIG. 2 . Therefore, when the rotating plate 150 rotates, the engaging end 151 provided by the bearing is engaged with the stopper 171 as if it were mounted on the stopper 171 , so that the rotation degree of the rotating plate 150 can be set to only about 180 degrees. Furthermore, since the base plate 170 and the rotating plate 150 are spaced apart by the predetermined distance G, the rotating plate 150 can be smoothly rotated.

The purpose of configuring the calibration machine 180 is to correct the rotation position of the barcode identification machine 110 when the barcode identification machine 110 rotates. Of course, the above-mentioned snap-on end 151 and stopper 171 can control the rotation amount of the rotating plate 150 and the barcode reader 110 more accurately, but in this embodiment, in order to correct more accurately after completing the 180-degree rotation, additional Equipped with correction machine 180. To this end, the calibration machine 180 includes a calibration pin 181 and a calibration cylinder 182, as shown in the extract of FIG. 5 .

The correction pins 181 are inserted into and removed from the correction holes 152 a and 152 b of the rotary plate 150 to correct the rotational position of the rotary plate 150 or to bring the rotary plate 150 into a rotatable state.

The correction cylinder 182 moves the correction pin 181 up and down to insert or remove the correction pin 181 from the correction holes 152a and 152b. That is, depending on which side of the electronic component the barcode is mounted on, and depending on the rotation state of the rotary plate 150, the calibration pin 181 is inserted into the calibration hole indicated by 152a or into the alignment hole indicated by the symbol 152b. allow.

Therefore, in this embodiment, through the clamping end 151 and the stopper 171 , the rotation position of the rotating plate 150 and the barcode identification machine 110 is fixed for the first time, and then the correcting machine 180 is used for the second precise fixation. < Description of the operation of the barcode recognition device > 1. First example of operation

If one side surface of the electronic component D has a barcode, the sorting machine is operated with the mirror 130 facing the side surface of the electronic component D. As shown in FIG. In this case, if there is a barcode on the other side of the electronic component D due to a change in the type of the electronic component D to be processed or the like, the rotating machine 160 operates to rotate the rotating plate 150 and the barcode reader 110 and the like 180 degrees, and the position of the rotating plate 150 is accurately corrected by the straightening machine 180 . By this correction of the position of the rotary plate 150, the position of the barcode reader 110 is also corrected. Then, in a state in which the position correction of the rotary plate 150 is completed, the processing for the electronic component D whose barcode is located on the other side is performed. 2. The second working example

This working example is applied to the case where there are barcodes on both sides of the electronic component D, and two barcodes need to be read. First, the pickup device makes one side surface of the electronic component D face the mirror 130 , and then lifts the electronic component D when the barcode on the one side surface is recognized. Then, the barcode reader 110 rotates 180 degrees with the electronic component D raised, the pickup device lowers the electronic component so that the mirror 130 faces the other side of the electronic component D, and then recognizes the barcode on the other side . < Additional considerations > 1. Relationship with pick-up device

Generally, a pickup device has a plurality of pickups in order to move a plurality of electronic components D. As shown in FIG. Each picker picks up one electronic component D, respectively. At this time, as shown in the reference diagram of FIG. 6 , if the barcode reader 110 rotates with the central axis 0 as a reference and changes from the state of (a) of FIG. 6 to the state of (b) of FIG. The barcode C of the electronic component D. Therefore, in order to make the barcode reader 110 face each barcode C in the electronic component D, it should be made into the state of (c) of FIG. Two techniques can be considered as a technique capable of appropriately converting the state of (a) of FIG. 6 to the state of (c) of FIG. 6 .

First of all, the first one is a technique of rotating the barcode reader 110 off-axis or moving the rotating machine 160 horizontally.

Secondly, the second is a technique that can be considered to move the pickup device PA through programmed motion control by taking advantage of the mobility basically possessed by the pickup device PA.

Depending on the designer, either the first technique or the second technique can be selectively used.

However, in the case where the barcode reader 110 is rotated off-axis or the rotary machine 160 is moved horizontally, it is not necessary to consider the horizontal movement of the pickup device PA, but it is additionally required for off-axis rotation of the barcode reader 110 or for The rotating machine 160 has a space for horizontal movement and is very complicated in mechanical structure. Therefore, taking advantage of the mobility basically possessed by the pickup device PA, the horizontal movement of the pickup device PA (refer to the arrow "K") is simultaneously performed by the general program action control, and the state transitions from FIG. 6( a ) accordingly. For the state of (c) of Fig. 6, this method can be recommended more preferably. 2. Correspondence between barcode recognition machine and electronic components

6(a) and (c), the correspondence between the barcode reader 110 and the electronic component D in the state of FIG. 6(a) is ①-ⓐ, ②-ⓑ, ③- ⓒ, ④-ⓓ, and correspondences ①-ⓓ, ②-ⓒ, ③-ⓑ, ④-ⓐ between the barcode reader 110 and the electronic component D in the state of (c) of FIG. 6 are different from each other.

That is, the correspondence between the barcode reader 110 and the electronic component D in the first mode, which is the basic mode without rotation, is changed to the barcode reader 110 and the electronic component D in the second mode in which the rotation of the barcode reader 110 is completed. It can be seen that the corresponding sequences between the barcode reader 110 and the electronic component D in the two modes are opposite to each other.

Therefore, it is necessary to correct the change in the order of the barcode reader 110 in the second mode, and accordingly, the electronic components of ①, ②, ③, ④ are in the order of ⓓ, ⓒ, ⓑ, ⓐ of the barcode reader 110 make changes. In this way, two techniques can be considered as a technique for changing the order.

The first is to assign an order to the terminal T electrically contacted to the barcode reader 110 as shown in (a) and (b) of FIG. 7 , so that the order of the barcode reader 110 can be maintained even if the barcode reader 110 is rotated Technology.

The second is a technique of changing the sequence according to the rotation state of the barcode reader 110 through programming.

In this matter, a technique of changing the sequence of the barcode reader 110 by programming is more preferably recommended in consideration of the complexity of mechanical structure implementation.

FIG. 8 illustrates the flow when the above-described relationship between the barcode reader 110 and the pickup device PA or the correspondence between the electronic components is realized through programming.

First, the manager of the sorter visually observes the electronic components D mounted on the customer tray, and confirms whether the placement position of the barcode C is on one side or the other side <S800>. If the equipped position of the barcode C is on one side, the sorting machine should work in the basic mode (ie, the first mode) in which the barcode reader 110 does not rotate. Therefore, the administrator selects the basic mode, namely the first mode <S811>, through the input unit provided in the sorter, and then puts the customer tray loaded with the electronic components D into the loading stacker <S813>, and make it work. According to this, the pickup apparatus PA operates to pick up and move the electronic component D located in the customer tray, and to perform the identification operation of the barcode C <S814>.

In addition, if the equipped position of the barcode C is on the other side, the sorting machine should work in the second mode in which the barcode reader 110 is rotated by 180 degrees. Therefore, the manager operates the second mode <S821> which is the change mode by selecting the input unit provided in the sorter. In this case, the sorting machine rotates the rotary plate 150 to rotate the barcode reader 110 by 180 degrees, and changes the order of correspondence of the barcode reader 110 corresponding to the electronic component D <S822>. Then, the manager puts the customer tray on which the electronic components D are loaded into the loading stacker <S823>, and makes it work. Accordingly, the pickup device PA works to pick up and move the electronic components D located in the customer tray, and the pickup device PA is moved horizontally so that the electronic components D correspond to the barcode recognition machines 110, respectively, so as to perform the barcode recognition operation of the barcode C. <S824>.

Of course, in the case where the barcode C is attached to both sides of the electronic component D, and the barcode C on both sides needs to be read, each time the barcode C is identified, the first mode and the second mode need to be performed. convert.

As described above, the barcode recognition device 100 needs to enable the pick-up device PA equipped with a plurality of pickers to realize the reading of the barcode C in the program of moving the electronic component, so the sorting machine needs to be equipped with the barcode recognition device 100 and the pick-up device PA. If programmatic control is required, the pick-up device D needs to be moved according to the corresponding order of the electronic component D and the barcode reader 110 or the rotation of the barcode reader 110 by the control unit loaded with the dedicated program.

As mentioned above, the specific description of the present invention is completed by referring to the embodiments of the accompanying drawings, but since the above-mentioned embodiments are only examples of the preferred embodiments of the present invention, the present invention should not be construed as being limited to the above-mentioned embodiments. For example, the right scope of the present invention should be understood by the claims and their equivalents.
