To ensure that the loading space of 111b is secured on one side in the longitudinal direction of the second tray 11b, the previously introduced empty magazine 111b can be moved to the other side in the longitudinal direction of the second tray 11b. In addition, the second tray 11b is set to a level that corresponds to the loading space on one side of the second tray 11b (more specifically, the width of the magazine) so that the loading space on one side of the second tray 11b is secured. The empty magazine (111b) can be transferred. In addition, the second clamp unit 112b holds the empty magazine 111b disposed in the loading space on one side of the second tray 11b for loading the return strip 110b, which will be described later, to secure the empty magazine 111b to the second tray 11b. It can be removed from the loading space on one side of the second tray (11b), and in the state where the empty magazine (111b) does not exist in the loading space on one side of the second tray (11b), the second clamp unit (112b) is additionally attached to another empty magazine ( When trying to grasp (secure) 111b), another empty magazine (111b) located on the other side of the loading space on one side of the second tray (11b) quickly moves to the loading space on one side of the second tray (11b) This may be provided to the second clamp unit 112b.

Here, the loading space is a second tray (11b) on which the empty magazine (111b) held by the first clamp unit (112a) can be placed when the first clamp unit (112a) is located in the waiting position of the second tray (11b). ), and in addition, while the first clamp unit 112a is located in the standby position of the second tray 11b, an empty magazine 111b that can be held from the second tray 11b is located. It can mean a space where Additionally, the second tray 11b may include a sensor that determines whether the empty magazine 111b is loaded (placed) in the loading space.

Hereinafter, unloading from the seating portion 1131 of the return strip 110b will be described.

The second clamp unit 112b may hold the empty magazine 111b or the second magazine 111c. When the second clamp unit 112b is not holding the magazine, it can move toward the second tray 11b and hold the empty magazine 111b loaded on the second tray 11b. Additionally, when the return strip 110b is loaded into the empty magazine 111b held by the second clamp unit 112b, the empty magazine 111b may become the second magazine 111c.

The second clamp unit (112b) grips the empty magazine (111b) or the second magazine (111c) partially loaded with the return strip (110b) so that the return strip (110b) from the seating portion (1131) is held by the empty magazine (111c) held by the second clamp unit (112b). 111b) or may be positioned in a ready position to be moved into the second magazine 111c. Specifically, when there is no magazine held, the second clamp unit 112b may move toward the second tray 11b and move to the ready position by holding the empty magazine 111b loaded on the second tray 11b. In addition, when the return strip 110b transferred from the seating part 1131 is loaded into the empty magazine 111b held by the second clamp unit 112b, the empty magazine 111b can become the second magazine 111c. And, the second clamp unit 112b can maintain the state of holding the magazine until it is impossible to load the return strip 110b into the held second magazine 111c.

In addition, when loading the return strip 110b into the held magazine (empty magazine 111b or the second magazine 111c) becomes difficult (in other words, the second clamp unit 112b clamps all of the return strips 110b with the return strip 110b). (filled state, etc.), the second magazine 111c being held can be introduced into the third tray 11c.

Also, for reference, if the second clamp unit 112b is to be moved to the ready position while the first clamp unit 112a is located in the ready position, the first clamp unit 112a must be moved to the lower side of the ready position. You can. The rail unit 115 may be extended lower than the first tray 11a so that the first clamp unit 112a can be positioned below when the second clamp unit 112b is in the ready position. . Accordingly, the first clamp unit 112a and the second clamp unit 112b, which share the same rail unit 115, can be positioned in the ready position when needed without mutual interference.

Additionally, the gripper 132 may push the return strip 110b seated on the seating portion 1131 toward the empty magazine 111b or the second magazine 111c. The return strip 110b seated on the seating portion 1131 by the push of the gripper 132 may be introduced into the empty magazine 111b or the second magazine 111c.

Referring to FIG. 7, the strip inspection module 113 is provided with an inner push unit 135 that further pushes the return strip 110b pushed by the gripper 132 toward the empty magazine 111b or the second magazine 111c. can do. For example, the return strip 110b seated on the seating portion 1131 is introduced into the empty magazine 111b or the second magazine 111c by the push of the gripper 132, and at least a portion of the empty magazine 111b is Alternatively, if the return strip 111c fails to flow into the second magazine 111c, the inner push unit 135 may additionally push the portion of the return strip 110b that has not flowed in, allowing the return strip 110b to completely flow into the magazine.

In summary, when the return strip 110b is seated on the seating portion 1131, the return strip 110b seated on the seating portion 1131 needs to be transferred into the empty magazine 111b or the second magazine 111c. In this case, the second clamp unit 112b is positioned in the ready position by gripping the empty magazine 111b or the second magazine 111c, and the gripper 132 holds the return strip seated on the seating portion 1131 ( 110b) can be pushed into the empty magazine (111b) or the second magazine (111c), and then the remaining portion of the pushed return strip (110b) that has not been pushed into the empty magazine (111b) or the second magazine (111c) is The inner push unit 135 may push additionally to completely insert (transfer) the empty magazine 111b or the second magazine 111c.

Additionally, the second clamp unit 112b can introduce the second magazine 111c into the third tray 11c. For example, when it is difficult to additionally load the return strip 110b onto the held second magazine 111c, the second clamp unit 112b moves the held second magazine 111c toward the third tray 11c. It can be moved. At this time, the second clamp unit 112b applies an external force in the other direction to the second magazine 111c introduced into the third tray 11c, so that the second magazine 111c flows into the third tray 11c, It can be moved to the other side of the third tray 11c.

Meanwhile, the seating portion 1131 may support at least a portion of the edge of the loaded input strip 110a or return strip 110b. For example, the seating portion 1131 may include a pair of supports 1311 and 1312 that are disposed at intervals in the width direction of the semiconductor strip and support each of one edge in the width direction and the other edge in the width direction of the semiconductor strip. there is.

Also, for reference, the pickup unit that transfers the input strip 110a seated on the seating unit 1131 to the cutting module 20 may pick up the input strip 110a loaded on the seating unit while contacting the upper surface of the input strip 110a.

In addition, the strip inspection module 113 is configured to detect the input strip 110a loaded on the seating unit 1131 when the pickup unit (not shown) contacts the upper surface of the input strip 110a loaded on the seating unit 1131. It may include a lift 134 that supports at least a portion of the portion excluding the edge from the lower side. For example, the lift 134 may be provided between a pair of supports 1311 and 1312, and may be arranged so that its upper surface faces at least a portion of the lower surface of the semiconductor strip seated on the seating portion 1131. Additionally, the lift 134 can move up and down and can optionally move upward to support the insertion strip 110a from the lower side. Accordingly, when the pickup unit contacts the upper surface of the semiconductor strip to proceed with the subsequent process, the lift 134 may move upward to contact and support the lower surface of the semiconductor strip. According to this, when the pickup unit contacts the semiconductor strip, each of the lower and upper surfaces of the semiconductor strip can be supported by contacting the lift 134 and the pickup unit, respectively, so that the semiconductor strip can be picked up by the pickup unit without being bent. To move the lift 134 up and down, the strip inspection module 113 may include a vertical moving cylinder structure in the lower part of the seating portion 1131 that moves the lift 134 up and down.

Additionally, the inner push unit 135 may be provided to move up and down and inward and outward for additional pushing as described above. Specifically, the inner push unit 135 may be located at a lower position compared to the strip seated on the seating portion 1131, and the gripper 132 pushes the return strip 110b to perform the primary movement of the return strip 110b. When this is completed, the return strip 110b, which is moved and pushed upward and pushed, may be positioned inside (or behind) the first moved return strip 110b, and the return strip 110b, which is moved and pushed in the outward direction, may be pushed in the outward direction to form the return strip. (110b) can be introduced into the empty magazine (111b) or the second magazine (111c).

Additionally, the inner push unit 135 may be vertically driven by a vertically moving cylinder structure. The inner push unit 135 may move upward in conjunction with the upward movement of the lift 134 to push the return strip 110b. Specifically, the lift 134 and the inner push unit 135 may be connected to the vertically movable cylinder structure, and the lift 134 and the inner push unit 135 may be moved up and down in conjunction with the vertically movable cylinder structure.

In addition, the inner and outer driving of the inner push unit 135 may be performed by the cylinder portion 1351. For example, referring to FIG. 8, the inner push unit 135 is provided on the outer surface of the lift 134. The cylinder portion 1351 may be provided to extend inward from the lower portion of the inner push unit 135 at the lower side of the lift 134, and may be provided to be able to extend (increase) in length in the outward direction. Accordingly, when the cylinder portion 1351 extends in length in the outward direction, the inner push unit 135 connected to the outer portion of the cylinder portion 1351 may be moved in an outward direction relative to the lift 134.

Additionally, referring to FIG. 9 , when the inner push unit 135 is moved outward from the lift 134, the position point (level) of the upper end of the inner push unit 135 may become higher. For example, referring to FIG. 8, the inner push unit 135 may be provided at an angle with respect to the vertical direction so that the upper part is located outside its lower part on the outer surface of the lift 134 (initial state), and the lift ( When the contact with 134 is released, it can be extended in the vertical direction, and when the inner push unit 135 is moved outward from the lift 134, the position point (level) of the upper end of the inner push unit 135 is moved to the lift (134). 134) can be higher than the upper surface (state after movement). Accordingly, the upper end of the inner push unit 135 may be positioned higher than the strip seated on the lift 134 or the initially moved return strip 110b when the inner push unit 135 moves in the outward direction, It contacts the return strip 110b and can be moved outward.

For reference, the lower portion of the inner push unit 135 and the cylinder portion 1351 may be hinged so that the inner push unit 135 can rotate outward by a predetermined amount or more about the connected portion. In addition, the lower part of the inner push unit 135 other than the hinged part and the other part except the hinged part of the cylinder part 1351 may be connected by an elastic body, and the elastic body may be connected to the above-mentioned part of the inner push unit 135. It can act as an elastic force that limits rotation. Accordingly, when a separate external force (for example, an external force greater than the elastic force of the elastic body) does not act on the inner push unit 135, the inner push unit 135 extends straightly (for example, vertically) in the vertical direction. It may have the state after the above-mentioned movement, and the inner push unit 135 is in contact with the outer surface of the lift 134, so that a support force in the outward direction by the lift 134 is applied to the upper part of the inner push unit 135. The inner push unit 135 may have the initial state as described above.

In summary, in the initial state, the upper part of the inner push unit 135 is positioned outside its lower part due to the elastic force in the inner direction acting on the lower part and the supporting force in the outward direction of the lift 134 acting on the upper part. It may be provided at an angle so as to move outward as the length of the cylinder portion 1351 extends, and when the contact with the lift 134 is released and the state after movement is reached, the cylinder portion 1351 is moved up and down by an inward elastic force acting on the lower portion. By being extended and arranged, it can have a higher top height than in the initial state, and using this, it can be moved outward in contact with the strip.

Additionally, referring to Figure 10, the strip recovery unit 11 may be provided with a first sensor unit 155. The first sensor unit 155 can detect whether the return strip 110b pushed by the inner push unit 135 is completely inserted into the empty magazine 111b or the second magazine 111c, and the return strip 110b When it is determined that the empty magazine 111b or the second magazine 111c has been completely inserted, the inner movement of the inner push unit 135 can be controlled to stop.

Additionally, referring to FIG. 5, the strip recovery unit 11 may be provided with a second sensor unit 154. The second sensor unit 154 can detect whether the semiconductor strip is seated on the seating unit 1131. For example, the second sensor unit 154 may be provided on the lower side of the inner portion of the semiconductor strip seated on the seating unit 1131 between a pair of supports 1311 and 1312. Accordingly, the second sensor unit 154 can determine whether the semiconductor strip is seated on the seating unit 1131 by detecting whether there is an inner portion of the semiconductor strip on the upper side.

Additionally, referring to Figure 10, the strip recovery unit 11 may be provided with a third sensor unit 153. The third sensor unit 153 can detect whether the semiconductor strip is seated on the seating unit 1131. For example, the third sensor unit 153 may be provided on the lower side of the outer portion of the semiconductor strip seated on the seating unit 1131 between a pair of supports 1311 and 1312. Accordingly, the third sensor unit 153 can determine whether the semiconductor strip is seated on the seating unit 1131 by detecting whether the outer portion of the semiconductor strip is present on the upper side.

Additionally, referring to Figure 10, the strip recovery unit 11 may be provided with fourth sensor units 151 and 152. The fourth sensor units 151 and 152 can detect whether the semiconductor strip is seated on the seating unit 1131. For example, the fourth sensor units 151 and 152 may include sensor 1 (151) and sensor 2 (152), where sensor 1 (151) is provided on the upper side of the seating unit 1131 and sensor 2 ( 152) is provided on the lower side of the seating unit 1131, and may be provided so that a path 1511 (for example, an optical stream) of mutually transmitted and received signals passes between a pair of supports 1311 and 1312. For example, semiconductor strips may have different specifications depending on the type. If the length of the semiconductor strip is short, the accuracy of detection by the second sensor unit 154 or the third sensor unit 153 may be reduced. In contrast, the strip recovery unit 11 is provided with the fourth sensor units 151 and 152, so that it can accurately detect whether the semiconductor strip is seated, regardless of the standard of the semiconductor strip.

According to the above, the return strip 110b, such as a strip to be recovered, a strip to be transferred to a separate processing device, etc., is an empty magazine or return strip held by the second clamp unit 112b from the strip inspection module 113 ( 110b) can be transferred to the loaded magazine, and if the return strip 110b is received, the second clamp unit 112b transfers the empty magazine held by it or the magazine loaded with the recovered semiconductor strip to the third tray 11c. It can be brought in. Accordingly, the return strip 110b can be automatically recovered and placed separately on the third tray 11c.

In summary, the strip recovery unit 11 of the input module 10 of the present system 1 determines whether the semiconductor strip needs to be recovered, and collects each injected semiconductor strip according to the determination result of whether the semiconductor strip needs to be recovered. Alternatively, it may be operated to insert the semiconductor strip into the cutting module 20.

Meanwhile, according to an embodiment of the present application, the reference insertion position preset for the semiconductor strip takes into account the cutting pattern of the cutting process performed in the cutting module 20 for cutting the semiconductor strip provided from the input module 10. It can be set as follows. For example, the strip adjusting unit 122 considers the cutting direction of the semiconductor strip of the cutting module 20 as shown in A of FIG. 11, so that the longitudinal direction of the held semiconductor strip is moved by the strip adjusting unit 122. The reference input position (hereinafter referred to as preset to be input into the cutting module 20) is adjusted to face a direction perpendicular to the direction of extension of the guide portion 123 (i.e., from 2 o'clock to 8 o'clock in FIG. 11) for guiding. , the length of the semiconductor strip, rotated based on the semiconductor strip (referred to as the first reference direction) or held in consideration of the cutting direction of the semiconductor strip of the cutting module 20 as shown in B of FIG. 11 After the direction is adjusted to face a direction parallel to the extension direction of the guide portion 123, the semiconductor strip is inserted into the cutting module 20 based on a preset reference insertion position (hereinafter referred to as the second reference direction).

The alignment module may be provided separately (in other words, the alignment module shown in A in FIG. 11 and the alignment module shown in B in FIG. 11 are provided independently and driven individually), but is not limited to this. As another example, the smart alignment unit 12 is implemented so that a single alignment module including the direction detection unit 121 and the strip adjustment unit 122 variably rotates the semiconductor strip in response to the first reference direction or the second reference direction. (In other words, a single alignment module may be implemented to variably rotate the semiconductor strip in the direction shown in A of FIG. 11 or the direction shown in B of FIG. 11).

In addition, the cutting module 20 includes a cutting assembly having a blade mounting portion (not shown), and the cutting assembly can cut the package from the semiconductor strip provided from the input module 10 and divide it into a plurality of packages, and can be cleaned.

In other words, the loading unit 41 may have an accommodating state in which packages are loaded, or a dry state in which a dry airflow is formed in an upward direction. Here, the receiving state of the loading unit 41 may mean a state in which a package is loaded on the loading unit 41.

Specifically, the loading unit 41 may be capable of moving up and down while the package is loaded thereon. A plurality of packages loaded on the loading unit 41 may have gone through a cleaning process by the cleaning module 30. In other words, the package moved from the cleaning module 30 through a cleaning process may be loaded in the loading unit 41. Additionally, the package may be loaded on the loading unit 41 so that the upper surface is exposed upward. The loading unit 41 can vacuum-adsorb the package. For example, the package may be seated on the loading unit 41 so that its lower surface is in contact with the upper surface of the loading unit 41. For example, a plurality of packages may be arranged in the loading unit 41 in n rows x m columns.

Additionally, referring to FIGS. 12 and 13 , the drying module 40 may include a flip portion 42. The flip unit 42 moves on the loading unit 41 and forms a dry airflow in the downward direction, providing a drying mode for drying the upper surface of the package loaded on the loading unit 41 and picking up the package loaded on the loading unit 41.

In this regard, the first air knife unit 431 may be referred to as a bottom air knife, and the second air knife unit 432 may be referred to as a top air knife.

In this regard, the dry state of the loading unit 41 may mean that the first air knife unit 431 disposed with respect to the loading unit 41 discharges gas in the upward direction to form a dry airflow. . For example, the upward direction may be an angular range including a direction inclined at a predetermined angle to the left from the vertical direction (approximately 10 o'clock to 11 o'clock direction). Accordingly, the dry airflow formed can be propagated (transmitted) not only in the upward direction but also in various directions within the space.

Specifically, the first air knife unit 431 disposed with respect to the loading unit 41 may form a dry airflow in the upward direction. For example, the first air knife unit 431 can form a dry airflow that propagates in various directions in space by discharging gas in an upward direction. As an example, the first air knife unit 431 may have a slit for discharging gas (dry air flow) formed along the longitudinal direction of the loading unit 41.

For example, the pickup unit 415 may be rotated so that its upper surface faces downward, and the pickup unit 421 may be capable of moving in the forward and backward directions. This pickup unit 421 can pick up the package by adsorbing it. For example, the pickup unit 421 is rotated so that the upper surface on which the package is adsorbed faces downward, and then moves forward to reach the upper side of the loading unit 41. The package moved to and loaded on the loading unit 41 can be picked up by adsorption. Additionally, the pickup unit 421 may perform a pickup mode by moving forward and backward while picking up the package. Additionally, the forward and backward movement of the pickup unit 421 may be linked to the forward and backward movement of the second air knife unit 432. Additionally, the rotation of the pickup unit 421 may be performed independently from the second air knife unit 432. The flip unit 42 can rotate the pickup unit 421 so that the pickup unit 421 and the second air knife unit 432 are driven in this way, and the pickup unit 421 and the second air knife unit 432 ) may include a jig unit 422 capable of moving in the forward and backward directions.

More specifically, the pickup unit 421 may be located at the rear of the loading unit 41 so that its longitudinal direction corresponds to the longitudinal direction of the loading unit 41. Accordingly, the pickup unit 421 can move onto the loading unit 41 and pick up the package loaded on the loading unit 41 just by moving in the front-back direction without moving in the longitudinal direction. In other words, the pickup unit 421 is located at the rear of the loading unit 41 so that its longitudinal direction corresponds to the longitudinal direction of the loading unit 41, so that the movement line and movement moving to pick up the package on the loading unit 41 and The movement line in the forward and backward directions on the loading unit 41 can be simplified.

Additionally, the flip part 42 may include a second air knife part 432. The second air knife unit 432 is provided along the longitudinal direction of the pickup unit 421 between the pickup unit 421 and the loading unit 41 to form a dry airflow in the downward direction. For example, the lower direction may be an angle range including a direction inclined at a predetermined angle to the right from the lower vertical direction (about 5 o'clock). For example, the second air knife unit 432 can form a dry airflow that propagates in various directions in space by discharging gas in a downward direction. As an example, the second air knife part 432 may have a slit for discharging gas (dry air flow) formed along the longitudinal direction of the flip part 42. In addition, the second air knife part 432 has a slit formed along the longitudinal direction of the flip part 42, so that a dry airflow can be formed corresponding to the longitudinal direction of the flip part 42. In addition, according to an embodiment of the present application, the second air knife unit 432 may move up and down or rotate on the side of the flip unit 42 to form a dry airflow in various directions. Additionally, the second air knife unit 432 can move in the forward and backward directions. For example, the second air knife unit 432 may be connected to the pickup unit 421, and accordingly, the second air knife unit 432 is linked to the forward and backward movement of the pickup unit 421, so that it moves back and forth. You can move in any direction.

As such, according to an embodiment of the present application, when the package is loaded on the loading part 41, the second air knife part 432 of the flip part 42 moves on the loading part 41 and flows dry air in the downward direction. By forming, the portion including the upper surface of the package can be dried by an airflow, and is disposed relative to the loading portion 41 when the package is moved on the loading portion 41 in a state picked up by the flip portion 42. The first air knife unit 431 forms a drying airflow in the upward direction, so that the portion including the lower surface of the package can be dried by the airflow. Accordingly, not only the upper surface but also the lower surface of the package can be dried by a dry air stream, so unlike the prior art, which removes moisture from the package by heat, stains remaining on the package can be prevented. In addition, by drying both the upper and lower surfaces of the package, the best dry condition of the package can be maintained and the drying efficiency of the package can be increased.

Meanwhile, according to an embodiment of the present application, the drying module 40 provides distance information (for example, in the front-back direction) between the reference position set for the loading unit 41 and the reference position set for the flip unit 42. The first air knife unit 431 and/or the second air knife unit ( Controlling the first air knife unit 431 and/or the second air knife unit 432 to adjust the dry air flow discharge direction (in other words, the opening direction of the slit) of 432) toward the area where the package is located. An airflow direction adjustment means (not shown) may be provided.

According to the above, the drying module 40 can perform the drying process through the following process.

First, when the package delivered from the cleaning module 30 is loaded, the loading unit 41 and the first air knife unit 431 move downward and move to the pickup unit 421 and the second air knife unit for a first predetermined time. The package can be placed in an accommodating state by loading it at a position lower than 432, and the second air knife unit 432 forms a dry airflow in the downward direction on the loading unit 41 for a first predetermined period of time, back and forth. You can perform dry mode by moving in the direction. Accordingly, a portion including at least a portion of the upper surface of the package can be dried by airflow.

After the first predetermined time, the pickup unit 421 moves onto the loading unit 41 to pick up the package loaded on the loading unit 41, and in the state of picking up the package, the first air is applied for a second predetermined time. Pick-up mode can be performed by moving in the forward and backward directions on the knife unit 431. To this end, the pickup unit 421 may rotate so that its upper surface faces downward before picking up the package to pick up the package on the loading unit 41. According to this, the package can be reciprocated in the front-back direction on the first air knife unit 431 with its lower surface exposed downward. Additionally, the first air knife unit 431 may be in a dry state by forming a dry airflow in the upward direction during the second predetermined time. According to this, the package can be moved back and forth in the forward and backward directions on the dry air stream formed by the first air knife part 431 with the lower surface exposed downward during the second predetermined time, so that the portion including at least a portion of the lower surface of the package It can be dried by an air current.

After the second predetermined time, the pickup unit 421 may reposition (reload) the package it was holding onto the loading unit 41. The package repositioning process is also similar to the package adsorption process, when the pickup unit 421 is located on the loading unit 41, the loading unit 41 is moved upward or the pickup unit 4221 is moved downward. The process of moving to can be accomplished. For reference, the first predetermined time may mean the time during which the portion including at least a portion of the upper surface of the package can be dried by the drying air flow, and more preferably, the time during which the portion including the entire upper surface can be dried. It can be. In addition, the second predetermined time may refer to the time during which the portion including at least a portion of the lower surface of the package can be dried by the drying air flow, and more preferably, the second predetermined time may be the time during which the portion including the entire lower surface of the package can be dried. You can.

When the package is repositioned in the loading unit 41, the pickup unit 421 and the second air knife unit 432 connected to the pickup unit 421 are moved to the initial position, that is, in the loading unit 41 and the first air knife unit 432. It can be moved to the rear of the knife unit 431, and the loading unit 41 and the first air knife unit 431 connected to the loading unit 41 are moved upward to the initial position, that is, the loading unit 41. It can be returned to the same level (height) position as.

In this way, when the drying process for the package is completed, the package can be moved to the table 60 by the first picker module 50 for subsequent processing.

According to the above-mentioned, when the package is loaded on the loading part 41, the flip part 42 moves on the loading part 41 and forms a drying airflow in the downward direction, so that the part including the upper surface of the package is dried by the airflow. It may be that, when the package is moved on the loading unit 41 in a state picked up by the flip unit 42, the loading unit 41 forms a dry airflow in the upward direction, so that the portion including the lower surface of the package is exposed to the airflow. It can be dried by Accordingly, not only the upper surface but also the lower surface of the package can be dried by a dry air stream, thereby preventing stains from remaining on the package.

In addition, according to the above-mentioned, when the package is loaded on the loading part 41, the flip part 42 moves on the loading part 41 and forms a dry airflow in the downward direction, so that the part including the upper surface of the package is affected by the airflow. When the package is moved on the loading unit 41 in a state picked up by the flip unit 42, the loading unit 41 forms a dry airflow in the upward direction, thereby drying both the upper and lower surfaces of the package. By doing so, the optimal drying condition of the package can be maintained and the drying efficiency of the package can be increased.

Additionally, the table 60 will be described below.

For reference, this system (1) includes a cutting process of cutting a semiconductor strip in which a plurality of packages are formed into individual packages, a cleaning process of cleaning the package cut in the cutting process, a drying process of drying the package cleaned in the washing process, and drying. Individual packages that have been inspected are manufactured from semiconductor materials by sequentially performing the package inspection process to check whether the completed package is defective and the off-load process to classify the package that passed the defect inspection and the package that did not pass the inspection result. It can be. As described above, the table 60 according to an embodiment of the present application is a package manufacturing device that performs the work of cutting, washing, drying, inspecting, and sorting packages by package unit, and stably vacuum-adsorbs individually cut packages.

The vacuum generator (not shown) connected to another picker in the state may have a grip release state, or may be neither in the grip state nor in the grip release state.

In addition, the classification module 90 will be described below. First, the package loading method using the reject bin 92 will be described with reference to FIGS. 14 and 15, and the tray 91 will be described with reference to FIGS. 16 and 17. ) will be explained about the package loading method using .

The classification module 90 disclosed herein may be provided with a receiving space in which each of a plurality of packages is accommodated according to the results of the inspection by the inspection module 80. In this regard, the second picker module 80 may transfer each of the plurality of packages held based on the inspection results by the inspection module 80 to the receiving space formed in the classification module 90.

Specifically, the inspection module 80 provides information on the presence or absence of defects that classifies each of the plurality of packages held by the second picker module 80 as a normal package or a defective package, and classification type information on the defect type of the package classified as a defective package. It can be derived as a test result. In other words, the inspection module 80 not only performs an inspection to classify each package as a normal package or a defective package, but also provides a function to determine the defect type of the package classified as a defective package. By way of example, the defect type information may include contamination, dimension (size) defect, ball attachment defect, etc., but is not limited thereto, and may be set to various types according to implementation examples of the present application, and disclosed herein The accommodation space provided in the classification module 90 may include a plurality of accommodation spaces according to defect presence information and classification type information for the detected defect.

14 and 15 are diagrams showing a reject bin of a classification module of a package cutting and sorting system according to an embodiment of the present application.

Meanwhile, according to an embodiment of the present application, each of the plurality of accommodation spaces formed in the reject bin 92 may correspond to each defect type of the defective package, but is not limited thereto, and according to the embodiment of the present application, Of course, a form in which some of the plurality of accommodation spaces of the reject bin 92 are used as spaces for loading normal packages and the remaining accommodation spaces are used as loading spaces corresponding to each defect type can also be applied. . For example, among the four accommodation spaces shown in FIGS. 14 and 15, the fourth accommodation space 92d, which has the largest volume, is a loading space for loading normal packages, and the remaining three accommodation spaces with relatively small volumes ( 92a, 92b, 92c) Each may be operated to accept defective packages corresponding to individual defect types.

As another example, the classification module 90 ensures that normal packages are seated in the receiving space formed in the tray 91, which will be described later, and defective packages are placed in each partitioned receiving space of the reject bin 92 according to classification type information. It may be that they are stored separately.

Meanwhile, referring to FIG. 15, the reject bin 92 includes an individual separation portion 922 provided to selectively separate the housing forming each receiving space and a body collectively separating the housing forming the receiving space as a whole. It may include an entire separation portion 921. For example, the manager or operator of the system 1 empties defective packages loaded in each receiving space or the entire reject bin 92 using the entire separation unit 921 or the individual separation unit 922. Alternatively, a separate reject bin picker module (not shown) may grasp the entire separation unit 921 or the individual separation units 922 and transfer the defective package to a separate space.

Meanwhile, according to an embodiment of the present application, the second picker module 70 obtains defect information and classification type information for each of the plurality of grasped packages from the inspection module 80, and selects the reject bin 92. After moving to the upper area, according to the result of matching the grip position information of each gripped package and the seating position information of each partitioned receiving space forming the reject bin 92, information on the presence or absence of defects specified for the corresponding receiving space and By selectively releasing the gripping state for the package corresponding to the classification type information, each package can be loaded (settled) into a pre-designated receiving space according to the defect presence information and the classification type information.

In addition, according to an embodiment of the present application, the second picker module 70 selects each receiving space provided in the classification module 90 according to the defect information and classification type information determined for each of the plurality of packages held. You can decide the movement order.

For example, normal packages are loaded (seated) on the tray 91, which will be described later, and defective packages are loaded (seated) in each receiving space formed in the reject bin 92 according to the classification type information, so that the classification module ( In a state in which 90) is operated, if the inspection module 80 determines that all of the plurality of packages currently held by the second picker module 70 are normal packages, the second picker module 70 selects the tray 91 ) side only to load (settle) the entire package, and then move to the reject bin 92 side and move to grip the next packages again. As another example, the second picker module 70 preferentially moves to the tray 91 or the reject bin 92 depending on the size relationship between the number of packages classified as normal packages and the number of packages classified as defective. , In a state where a plurality of defective packages corresponding to different classification type information are held, the second picker module 70 is directed toward the accommodation space of the reject bin 92 corresponding to the relatively large number of classification type information held. The loading (seating) order for each package, such as preferential movement, can be varied and applied according to the implementation example of the present application.

Figures 16 and 17 are diagrams for explaining a package loading method using a tray of a classification module of a package cutting and sorting system according to an embodiment of the present application.

In addition, the tray transfer unit 900 is arranged to extend in the Y-axis direction and is disposed on the other side of the first rail 910a in the X-axis direction to prevent the movement of the tray unit (second tray unit) including the second tray 91b. The guiding second rail 910b is extended in the Y-axis direction and is disposed on the other side of the second rail 910b in the X-axis direction to prevent the movement of the tray unit (third tray unit) including the third tray 91c. It may include a third rail 910c for guidance.

On one side of each of the first rails (910a) to the third rails (910c) in the Y-axis direction, there is a loading waiting area where package placing is performed for the trays seated on each of the first trays (91a) to the third trays (91c). An exchange waiting area is formed on the other side of each of the first rails (910a) to the third rails (910c) in the Y-axis direction, where trays for each of the first trays (91a) to the third trays (91c) are supplied and collected. This can be formed. For example, when the first tray 91a is located in the exchange waiting area, a new tray may be supplied (seated) in the first tray 91a, and the first tray 91a supplied with the new tray will be moved to the loading waiting area. Packages that have been moved and judged to be good can be transferred. In addition, when the package placing for the tray of the first tray 91a is finally completed, the first tray 91a can be moved to the exchange waiting area, and the tray on the first tray 91a can be recovered. , a new tray may be supplied to the first tray 91a. Since the driving of the second tray 91b is similar to the driving of the first tray 91a, detailed description is omitted.

Once loading is completed, packages judged to be good quality can begin to be loaded onto other trays, and the tray on which loading was completed first can be moved to the exchange waiting area, collected, and then supplied with a new tray and moved to the loading waiting area. For example, when placing of a package on a tray begins, a package that has been determined to be good may be loaded on the tray of the first tray 91a. At this time, the tray of the first tray 91a is in a full state. Until this happens, the package can be placed on the tray of the first tray 91a (at this time, the tray of the second tray 91b is in a standby state). Thereafter, when the tray of the first tray 91a is in a full state, the first tray 91a is moved to the exchange waiting area and placing of the package on the tray of the second tray 91b may begin, and the first tray 91a When the full tray loaded in the exchange waiting area is retrieved and a new tray is supplied, the tray of the tray 91a moves to the loading waiting area and can wait until the tray of the second tray 91b becomes full. And when the tray of the second tray (91b) is in a full state, the second tray (91b) can be moved to the exchange waiting area, and package placing for a new tray of the first tray (91a) can be started. .
