Description

Bar code recognition device of sorting machine for electronic component processing

The present invention relates to a barcode recognition device that is applied to a sorting machine that processes electronic components and recognizes barcodes printed or affixed to electronic components.

At present, the information of electronic components is managed in a lot (LOT) unit in a sorting machine.

In most cases, in order to prevent batches with different amounts from being mixed, the sorting machine is run once based on the batch amount. However, large-scale electronic components, such as random access memory (RAM) modules, which are loaded with dozens of electronic components, are specialized for the final production products, so the quantity of a batch is small. Therefore, in order to process a plurality of batches of material, the sorting machine needs to be operated multiple times, which will cause a reduction in the operating rate of the sorting machine.

Therefore, in recent years, the history (production factory or production line, batch information, etc.) and test results of the corresponding electronic component are independently managed by identifying the barcode of the electronic component. To this end, the sorting machine is correspondingly equipped with a barcode recognition machine capable of recognizing barcodes. In this case, the sorting machine is equipped with a bar code recognition machine to be able to recognize a bar code located on a specific side of the electronic component, and in consideration of the efficiency of the operation, the bar code recognition machine is arranged on the moving path of the electronic component.

However, if the electronic component is specialized for the final production product, the situation where the position of the bar code is on the reverse side cannot be ruled out. In this case, you can only use a sorter that can recognize the bar code located on the opposite side. This is a cost burden for consumers of the sorting machine, and it is not preferable in terms of space utilization. In addition, even if this sorter can process the quantity of multiple batches, it is not possible to run the sorter once to process batches whose barcode positions are on different sides from each other, so the operating rate will decrease accordingly.

Therefore, the applicant of the present invention has proposed a bar code through Korean Published Patent 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 the identifier selectively reads all barcodes on both sides of an electronic component.

Usually, in a sorting machine, the movement of electronic components is performed by a pick-up device or by a moving shuttle. The prior art 1 illustrates an example of reading a barcode of an electronic component in a state picked up by a pickup device, and the prior art 2 illustrates an example of reading a barcode of an electronic component loaded on a moving shuttle.

The prior art 1 is equipped with a bar code sorter that is twice as many as the number of electronic components picked up by the pick-up device, so that all the barcodes that may be selectively located on both sides of the electronic components can be read selectively. In this case, the interval between the electronic components picked up by the pickup device must be sufficiently large, and therefore, the interval between the individual pickups constituting the pickup device needs to be sufficiently ensured. Also, due to this, it is necessary to enlarge the overall size of the pickup device or to equip an additional drive unit for adjusting the pitch between individual pickups, and to ensure the space occupation rate of the pickup device in the device. In this case, due to the size of the pick-up device, complicated design aspects for solving the interference problem of its moving path, etc., or due to the enlargement of the device itself, the configuration of the drive unit, and the increase in the number of barcode recognition machines 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 a mirror, it still has limitations in reducing the size of the pickup device, so it still has the same effect as the number of cameras. Increased pressure on rising production costs.

In addition, in the prior art 2, the barcode identification machine is rotated by a predetermined angle to selectively read all the barcodes that may be selectively located on both sides of the electronic component. According to the prior art 2, because the recognition direction of the barcode recognition machine will have an inclination, the reading rate will be reduced, so a high-priced barcode recognition machine is also needed, and in order not to be attached to the barcode (the barcode is attached to the upper side (Or the lower side) can be read all affected areas, it is necessary to fully ensure the spacing between electronic components. Therefore, there are considerable problems similar to those of the prior art 1.

An object of the present invention is to provide a technology related to a bar code identification device that improves the prior art 1 and the prior art 2 more developmentally, thereby minimizing the expansion of equipment or increasing the production cost and increasing the recognition rate thereof.

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

According to a first aspect of the present invention, a bar code identification device for a sorting machine for processing electronic components includes one or more bar code identification machines for identifying bar codes on electronic components moving along a predetermined movement path; and a rotating machine for The bar code identification machine rotates 180 degrees forward and backward so that the bar code identification machine can identify all or selectively identify the bar codes located on one side and the other side of the electronic component, respectively.

The barcode identification device of the sorting machine for processing electronic components further includes: a rotating plate provided with the one or more barcode identifying machines and rotated by the rotating machine; and a base plate provided with the rotating machine. The rotating plate and the base plate are separated from each other.

The base plate is provided with a snap-in end, and the base plate is provided with a stopper, and the snap-in end will be snapped by the stopper when the rotating plate rotates, and the rotation degree of the rotating plate is set accordingly .

The barcode recognition device of the sorting machine for electronic component processing may further include a correction machine, and if the one or more barcode recognition machines are rotated by the rotary machine, correcting the rotation position of the one or more barcode recognition machines. .

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

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

The barcode recognition machine is provided in a plurality, and in a case where the rotary machine rotates a plurality of the barcode recognition machines, a corresponding order of the plurality of barcode recognition machines is changed.

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

According to the present invention, there is an effect that it is possible to minimize the enlargement of equipment or increase in production cost, and to increase the barcode recognition rate.

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

FIG. 1 is a partially exploded perspective view of a bar code identification device 100 (hereinafter referred to simply as a “bar code identification 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 and a setting plate 140, a rotating plate 150, a rotating machine 160, a base plate 170, and a correction machine 180.

The four bar code recognition machines 110 are provided for individually identifying the bar codes of the electronic components D that are moved along the 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 situation. With such a barcode recognition machine 110, it is also possible to confirm whether the electronic component D is inserted in the reverse direction, and if equipped with a camera, it is also possible to confirm whether a foreign object is attached or whether the barcode is defective.

For reference, the barcode 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 device required for sorting or testing the electronic component D It can be used as a reference when controlling.

The height adjustment machine 120 is provided for improving the barcode recognition rate by adjusting the equipped height of the barcode recognition machine 110. In this embodiment, a long slot is formed in the height adjustment machine 120 in the up-down direction, and the height of the barcode recognition machine 110 can be manually adjusted by using the mounting bolt B. However, as long as the structure can lift and lower the barcode recognition machine 110, Any of them can be considered preferably, and it is entirely conceivable to use a motor or the like for automatic adjustment.

The mirror 130 is provided for refracting light by 90 degrees so as to transmit an image of a barcode of the electronic component D to a barcode recognition machine 110 located below the lens barrel MT. That is, if the pick-up device lowers the electronic component D, the portion of the electronic component D picked up by the pick-up device with a barcode will be located at least between the reflectors 130. Based on this, the barcode recognition machine 110 will read through each of the reflectors 130 Like the barcode.

The setting plate 140 is provided for mounting the reflecting mirror 130 and the barcode recognition machine 110 by supporting the lens barrel MT.

The purpose of equipping the rotating plate 150 is to finally set the reflecting mirror 130 and the barcode recognition machine 110 rotatably 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 into a single body by a predetermined height of the pitch maintaining lever GR. Therefore, if the rotating plate 150 rotates, the setting plate 140 will also rotate by the same angle, and the reflector 130 and the barcode recognition machine 110 provided 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 bar code recognition machines 110 can be rotated together by one rotating machine 160 is realized.

In addition, as shown in the extract of FIG. 2, in order to set the rotation degree of the rotating plate 150 to 180 degrees, the rotating plate 150 is provided with two clip ends 151 on both sides, and also has two Correction holes 152a, 152b for correcting the position. In this embodiment, the two snap-on ends 151 are equipped with bearings. The snap-on ends 151 and the correction holes 152a and 152b will be described below.

The rotating machine 160 is provided in order to rotate the rotating plate 150 by 180 degrees. Through such a rotating machine 160, the rotating plate 150 and the bar code recognition machine 110 finally disposed 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. According to this, the bar code recognition machine 110 can It is in a state where all the barcodes on one side and the other side of the electronic component D can be identified or selectively identified. To this end, as shown in the extract of FIG. 3, the rotating machine 160 includes a driving cylinder 161, a rotating belt 162, a coupling block 163, a first pulley 164a, a second pulley 164b, a rotating member 165, a reference member 166, and an adjusting member 167. And setting part 168.

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

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

The coupling block 163 couples the forward and backward lever FB of the driving cylinder 161 to the rotating belt 162. Therefore, if the driving cylinder 161 operates, the rotating belt 162 will rotate with the two pulleys 164a, 164b as the rotation switching points.

The first pulley 164a and the second pulley 164b are provided in order to provide the rotating belt 162. Such a first pulley 164 a and a second pulley 164 b provide a rotation conversion point of the rotation belt 162 and rotate in conjunction with the rotation of the rotation 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 such a rotating member 165, the rotating plate 150 will rotate in conjunction with the rotation of the rotating member 165 . Due to this structure, if the driving cylinder 161 works, the rotating belt 162 will rotate with the two pulleys 164a and 164b as the rotation conversion points. At this time, the rotation member 165 and the second pulley 164b will rotate in conjunction with each other, and the rotating plate will rotate. 150 will also rotate.

The reference member 167 is provided for adjusting the position of the setting member 168 in combination with the base plate 170.

The adjusting member 167 is screwed together and passes through the reference member 166 while the end thereof contacts the setting member 168. Therefore, if the adjustment member 167 is rotated, the adjustment member 167 is moved by tightening or loosening the screws, and in conjunction with this, the position of the adjustment member 168 is adjusted while the setting member 168 is moved.

The setting member 168 is provided for setting the first pulley 164a. As shown in the cut-away view of FIG. 4, such a setting member 168 is movably coupled to the base plate 170. For this reason, the installation member 168 is formed with a long slot LH in the moving direction, and is configured such that the coupling bolt JB is coupled to the base plate 170 through the slot LH. Therefore, the installation member 168 can be moved somewhat. The setting member 168 can be guided and moved by a moving groove MG formed in the base plate 170 by a cutting machine.

As described above, the position of the setting member 168 can be changed in order to maintain the tension of the rotating belt 162. The tension of the rotating belt 162 may change due to the weight of the combined materials or sagging due to use or the temperature of each season. In this case, it is difficult to complete the accurate rotation of the rotating plate 150 through the rotating belt 162. Therefore, in this embodiment, by using the adjustment member 167 to move the setting member 168, the tension of the rotating belt 162 is maintained at an appropriate level, so that the rotating plate 150 is accurately rotated.

For reference, in this embodiment, in order to reduce production costs, the driving cylinder 161 is used to rotate the rotating plate 150. However, depending on the implementation, the rotating plate 150 may be simply implemented by a forward and reverse rotation motor.

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

The purpose of configuring the correction machine 180 is to correct the rotation position of the barcode recognition machine 110 when the barcode recognition machine 110 is rotated. Of course, the rotation amount of the rotary plate 150 and the barcode recognition machine 110 can be controlled more accurately through the already mentioned snap-in ends 151 and the stoppers 171, but in this embodiment, in order to more accurately correct after completing a 180-degree rotation, additional Equipped with correction machine 180. To this end, as shown in an excerpt of FIG. 5, the correction machine 180 includes a correction pin 181 and a correction cylinder 182.

The correction pin 181 is inserted into or detached from the correction holes 152 a and 152 b of the rotation plate 150 to correct the rotation position of the rotation plate 150 or to turn the rotation plate 150.

The correction cylinder 182 raises and lowers the correction pin 181 to insert or remove the correction pin 181 into or from the correction holes 152a and 152b. That is, according to which side of the electronic component the barcode is equipped with, and according to the rotation state of the rotating plate 150, the correction pin 181 is inserted into the correction hole with the symbol 152a, or the correction hole with the symbol 152b. quasi.

Therefore, in this embodiment, the rotation positions of the rotation end 150 and the bar code recognition machine 110 are fixed for the first time by the clip end 151 and the stopper 171, and then accurately fixed for the second time by the corrector 180. ＜ Description of the operation of the bar code recognition device ＞ 1 、 First working example

If a barcode is provided on one side of the electronic component D, the sorting machine is operated with the reflector 130 facing the side of the electronic component D. 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, etc., the rotary machine 160 works to rotate the rotary plate 150 and the barcode recognition machine 110 and the like. 180 degrees, and the position of the rotating plate 150 is accurately corrected by the corrector 180. By such a position correction of the rotary plate 150, the position of the barcode recognition machine 110 is also corrected. Then, the processing for the electronic component D whose barcode is located on the other side is performed in a state where the position correction of the rotary plate 150 is completed. 2. Second working example

This working example is applied to the case where both sides of the electronic component D have barcodes, and two barcodes need to be read. First, the pick-up device faces one side of the electronic component D and the reflecting mirror 130, and then if the identification of the barcode on the one side ends, the electronic component D is raised. Then, when the electronic component D is raised, the barcode recognition machine 110 rotates 180 degrees, and the pick-up device lowers the electronic component so that the reflecting 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 pickup device

Generally, a pickup device has a plurality of pickers in order to move a plurality of electronic components D. Each picker picks up an electronic component D. At this time, as shown in the reference diagram of FIG. 6, if the barcode recognition machine 110 rotates with the central axis 0 as a reference, and changes from the state of (a) in FIG. 6 to the state of (b) in FIG. Bar code C of the electronic component D. Therefore, in order for the barcode identification machine 110 to face each barcode C in the electronic component D, it should be made to the state of (c) of FIG. 6. As a technique capable of appropriately converting the state shown in FIG. 6 (a) into the state shown in FIG. 6 (c), two kinds of techniques can be considered.

First, the first is a technology that can consider rotating the barcode identifying machine 110 off-axis or rotating the rotating machine 160 horizontally.

Secondly, the second is a technology that can consider moving the pickup device PA through programmatic action control using the mobility of the pickup device PA.

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

However, when the bar code recognition machine 110 is rotated off-axis or the rotary machine 160 is moved horizontally, it is not necessary to consider the horizontal movement of the pick-up device PA, but it is additionally necessary to rotate the bar code recognition machine 110 off-axis or to make the bar code recognition machine 110 off-axis. The space where the rotating machine 160 moves horizontally is very complicated in terms of mechanical structure. Therefore, using the basic mobility of the pick-up device PA, the horizontal movement of the pick-up device PA (see arrow "K") is performed along with the program-type action control, and the state is changed from the state shown in FIG. 6 (a). In the state of (c) of FIG. 6, this method can be more preferably recommended. 2. Correspondence between barcode recognition machine and electronic components

In addition, referring to FIGS. 6 (a) and (c), the correspondence relationship between the barcode recognition machine 110 and the electronic component D in the state of FIG. 6 (a) ①-ⓐ, ②-ⓑ, ③- Correspondences, ④-ⓓ, and the barcode identification machine 110 and the electronic component D in the state of FIG. 6 (c) ①-①, ②-ⓒ, ③-ⓑ, ④-ⓐ are different from each other.

That is, the correspondence between the barcode recognition machine 110 and the electronic component D in the first mode as the basic mode without rotation is changed to the barcode recognition machine 110 and the electronic component D in the second mode that completes the rotation of the barcode recognition machine 110. Corresponding relationship between the two, it can be known that the correspondence order between the barcode recognition machine 110 and the electronic component D is opposite to each other in the two modes.

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

The first is as shown in (a) and (b) of FIG. 7, the order is given to the terminals T that are in electrical contact with the barcode recognition machine 110, so that the sequence of the barcode recognition machine 110 can be maintained even if the barcode recognition machine 110 rotates. Technology.

The second is a technique of programmatically changing the order according to the rotation state of the barcode recognition machine 110.

In this matter, in view of the complexity of the realization of the mechanical structure, it is more preferable to recommend a technique for changing the order of the barcode recognition machine 110 in a programmatic manner.

FIG. 8 illustrates a flow when the above-mentioned relationship between the barcode recognition machine 110 and the pick-up device PA or the correspondence relationship with the electronic components is realized by programming.

First, the manager of the sorting machine visually observes the electronic component D loaded on the customer tray, thereby confirming whether the installation 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 operate in the basic mode (ie, the first mode) in which the barcode recognition machine 110 does not rotate. Therefore, the manager selects the input mode of the sorting machine to make it work in the basic mode, that is, the first mode <S811>, and then puts the customer tray loaded with the electronic component D into the loading stacker <S813>, And make it work. Accordingly, the pick-up device PA works to pick up and move the electronic component D located in the customer tray, thereby performing the identification operation <S814> of the barcode C.

In addition, if the equipped position of the barcode C is on the other side, the sorting machine should work in the second mode where the barcode recognition machine 110 is rotated 180 degrees. Therefore, the manager selects the input unit provided in the sorting machine to make it work in the second mode <S821> as a change mode. In this case, the sorting machine rotates the rotating plate 150 to rotate the barcode recognition machine 110 by 180 degrees, and changes the corresponding order of the barcode recognition machine 110 corresponding to the electronic component D <S822>. Then, the manager puts the customer tray on which the electronic component D is loaded into the loading stacker <S823> and makes it work. According to this, the picking device PA works to pick up and move the electronic component D located in the customer tray, and makes the picking device PA move horizontally so that the electronic component D corresponds to the barcode recognition machine 110, respectively, so that the barcode C is identified. <S824>.

Of course, when 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 recognized, the first mode and the second mode need to be performed. Conversion.

As described above, the barcode identification device 100 needs to enable the pickup device PA equipped with multiple pickups to read the barcode C in the program of the mobile electronic component, so the sorting machine needs to be equipped with the barcode identification device 100 and the pickup device PA. If programmatic control is required, the pick-up device D needs to be moved along with the position according to the correspondence order between the electronic component D and the barcode recognition machine 110 or the rotation of the barcode recognition machine 110 by a control section loaded with a dedicated program.

As mentioned above, the specific description of the present invention has been completed by referring to the embodiments of the drawings, but since the above embodiments only illustrate the preferred embodiments of the present invention, the present invention should not be understood as being limited to the above implementations only For example, the scope of rights of the present invention should be understood by the claims and their equivalents.
