Description

Transmission equipment

The present invention relates to the technical field of a transmission device, and more particularly to a transmission device.

When a process of producing a component is performed or a designated operation is performed on the produced component, there is a case where the component is transferred by a conveying device. At this point, the parts should be stably held and loaded onto the transfer equipment. Such conveying equipment may be, for example, various equipment including a tray and a processing machine.

Such a transfer device supports a work device to perform a designated operation on a target object. For example, the transfer device is electrically connected to the tester, and the electronic components are moved to the tester side for testing. Then, the transfer device performs a job of unloading the target object that has completed the designated job.

In addition, in order to reduce the number of transfer times of the target object and operate the multiple target objects, the transfer device may load the multiple target objects on a tray. When the target object is loaded into the tray, the tray is horizontal. After completing the pallet loading operation of a plurality of target objects, the transfer device transfers the pallet to the working device. At this time, the position of the tray remains horizontal during the process of transferring the tray. Then, the working device operates the target object to be transferred.

Recently, the number of such operations to be performed on target objects has been increasing. That is, as the number of jobs that need to be performed on the target object increases, the number of work devices that perform the job also increases. For example, in the past, 32 kinds of parameter tests were performed on semiconductor devices, but now the number of tested parameters has increased to 128 kinds of parameter tests. In addition, in response to an increase in the number of jobs, the number of working devices for performing the jobs has also increased.

However, when the position of the tray is maintained only in a horizontal state, the working device should also be set to be able to operate the tray in a horizontal state. In this case, since an excessive number of working devices are installed in the horizontal space in a state of being laid horizontally, there is a problem that an excessively wide operating space is required to arrange the working devices.

In addition, when the position of the tray is maintained only horizontally, the transfer of the tray is also restricted. That is, when the position of the trays is maintained only in a horizontal state, in order to avoid conflicts between the transfer trays, it is necessary to ensure a relatively wide transfer space. For these reasons, there is a problem that the size of the transfer equipment becomes too large.

Therefore, when the transfer device transfers the tray, the position of the tray needs to be changed. Optionally, the position of the pallet needs to be converted from a horizontal position to a position other than the horizontal position, and then from a position other than the horizontal position to the horizontal position.

However, when the transfer device changes the position of the tray, the target object placed on the tray has a risk of falling off the tray. Therefore, it is necessary to prevent the target object from falling off the tray when the transfer device changes the position of the tray.

An embodiment of the present invention provides a transfer device capable of minimizing a space required for a tray operation and a tray transfer to solve the above-mentioned existing technical problems.

In addition, there is provided a transfer device capable of preventing a target object from falling out of the tray when transferring the tray.

1 to 6, a transfer device 1 according to a first embodiment of the present invention is configured to be capable of transferring a target object 2. For example, the loaded target object 2 may be placed on a tray 10 to be described later, and the tray 10 may be placed horizontally in the device area 3. The pallet 10 in the device area 3 is loaded to the conveying device 1 by a loading structure. Such a loading and unloading structure may include a cylinder, a motor, a piston, a gripper, and the like, and may be provided on at least one of the conveying device 1 and the device area 3. The transfer device 1 loaded with the tray 10 may transfer the tray 10 from the device area 3 to the work device 4, and may include a tray transfer device for transferring the tray 10. Such a tray transfer device includes a driving unit such as a motor, and since the implementation manner is obvious to those skilled in the art, it will not be repeated here. In addition, the conveyance device 1 can supply the tray 10 to the working device 4 in a state of standing upright. After the work in the working device 4 is completed, the conveyance device 1 may re-transfer the tray 10 from the working device 4 to the device area 3 and bring the tray 10 in a horizontal state.

In addition, in the drawing according to the present embodiment, the tray 10 is placed in a horizontal posture in the device area 3, and the tray 10 is placed in a vertical posture in the work device 4, but the concept of the present invention is not limited thereto, In addition, the transfer device 1 can also prevent the tray 10 from changing its position during the transfer. In addition, In the drawing according to the present embodiment, the target object 2 is shown as an IC module such as a semiconductor wafer, but this is only an example. In addition, the conveyance device 1 is described above as conveying a tray to perform a job such as a test in the work device 4, but this is only an example, and the concept of the present invention can be applied to all the conveyance devices 1 including the tray 10.

The conveyance device 1 includes a tray 10, a tray carrying portion 20, a fall-off prevention device 30, and a control portion 40.

The tray 10 can store the target object 2. That is, the target object 2 may be loaded on or unloaded from the tray 10. In addition, the tray 10 may be provided with a groove, a slit, or the like capable of accommodating the target object 2.

The tray carrying portion 20 can selectively load the tray 10. Such a tray supporting portion 20 can raise and lower the tray 10 and can rotate the tray 10 according to specific conditions. In addition, the tray carrier 20 can also transfer the tray 10 along a predetermined path.

For example, the tray carrier 20 may load a tray 10 placed in the device area 3. The tray carrying portion 20 may include at least one of a piston, a driving motor, and a cylinder, but is not necessarily limited thereto. The tray carrying portion 20 may include guides, rollers, and the like that guide the tray 10, making it easier to mount the tray.

In addition, when the tray carrying portion 20 is rotated in a state in which the tray 10 is loaded, the posture of the tray 10 may be changed. For example, according to the rotation of the tray carrying portion 20, the posture of the tray 10 may be changed from the horizontal state 10 'to the vertical state 10 ". The tray carrying portion 20 may include a rotor 21 for rotation.

The fall prevention device 30 can selectively prevent the target object 2 from falling out of the tray 10. For example, the fall-off prevention device 30 may be in a state where the target object 2 is prevented from falling out of the tray 10 (fall-off state), or may be in a state where the target object 2 is allowed to fall freely from the tray 10 (released state).

In addition, as shown in the drawing of this embodiment, when the anti-falling device 30 is located at the anti-dropping position, it is in contact with one side of the target object 2, and when the anti-falling device 30 is in the released state, it moves to both sides of the tray 10, but These are examples only and are not necessarily limited to this. In addition, as shown in the drawings of this embodiment, the fall-off preventing device 30 is provided on the tray 10, but it is not necessarily limited to this. For example, the anti-falling device 30 may also be provided on the tray supporting portion 20, and a part of the structure may be provided on the tray 10 and the remaining structure may be provided on the tray supporting portion 20.

The fall prevention device 30 may include a fall prevention member 100 and a moving unit 200.

The fall prevention member 100 may include a fall prevention portion 110 capable of preventing a target object loaded on the tray 10 from falling out, and a lever portion 120 connected to a moving unit 200 to be described later. As shown in the drawings of this embodiment, the fall-off prevention portion 110 includes a bar-shaped elongated member, but it is not necessarily limited to this.

The mobile unit 200 includes a hinge 210, an elastic member 220, and a body 230. The hinge 210 and the elastic member 220 may be supported by the body 230. The fall-off prevention member 100 and the main body 230 are connected by such a hinge 210 and the elastic member 220. Thereby, the fall-off prevention member 100 can be supported by the moving unit 200.

In addition, the hinge 210 and the elastic member 220 of the moving unit 200 can rotate the anti-falling member 100 together with the pressing device 300 to be described later. Moreover, in order to make the rotation of the anti-falling member 100 smoother, the hinge 210 may be disposed between one side 121 of the lever portion 120 and the other side 122 of the lever portion 120. That is, the hinge 210 functions as a rotation center of the lever portion 120. In addition, the hinge 210 may be provided between a position pressed by the elastic member 220 and a position pressed by the pressing device 300. For example, the elastic member 220 applies an elastic force to one side 121 of the lever portion 120, and the lever portion 120 rotates in one direction with the hinge 210 as a center by this elastic force. At this time, the fall-off preventing member 100 is in a fixed state and is supported (fixed state) by a support portion 250 to be described later. In addition, the pressing device 300 applies pressure to the other side 122 of the lever portion 120, and the lever portion 120 rotates in the other direction with the hinge 210 as a center by a force received from the pressing device 300. At this time, the fall-off preventing member 100 is detached from the support portion 250 and is released from the fixing, so that it is in a movable state (movable state).

In addition, the mobile unit 200 may further include a guide 240. The guide 240 can guide the body 230 to move between the drop-off prevention position and the release position. The body 230 is configured to be connected to the guide 240 and to be selectively movable along the guide 240. The guide 240 may be a linearly extended protruding or recessed track.

The body 230 is formed with a hole 231 and a stopper 232. The hole 231 is formed with an opening toward the pressing device 300 into which the pressing device 300 can be inserted. Thereby, the pressing device 300 can apply pressure toward a more accurate position when applying pressure to the fall-off prevention member 100. In addition, in order to make the pressing device 300 easier to insert, a bearing 233 is provided on an inner wall of the hole 231. The stopper 232 may be formed inside the body 230 and may selectively contact the lever portion. Such a brake 232 can prevent excessive rotation of the lever portion 120. For example, when the lever portion 120 is not subjected to the force of the pressing device 300 but is subjected to the elastic force of the elastic member 220, the lever portion 120 is in contact with the brake 232. This can prevent the lever portion 120 from being excessively rotated by the elastic force of the elastic member 220 by the brake 232.

In addition, the moving unit 200 may include a support portion 250 capable of selectively accommodating the fall-off preventing member 100. By accommodating the fall prevention member 100 in the support part 250, the position of the fall prevention member 100 can be fixed more easily. Also, the support portion 250 may include a first support portion 251 and a second support portion 252. The first support portion 251 can accommodate the fall-off prevention member 100 when the fall-off prevention device 30 is in a position capable of preventing the target object 2 from falling off. When the anti-falling device 30 is placed on the target object 2 relative to the tray In a position where loading and unloading are not restricted, the second support portion 252 can accommodate the fall-off preventing member 100. When the fall-off prevention member 100 is accommodated in the support portion 250, the fall-off prevention member 100 can be more effectively prevented from moving in the X direction.

In addition, the moving unit 200 may be provided at both end portions of the drop-out preventing member 100. In this case, the support and movement of the fall-off prevention member 100 can be made smoother.

In addition, as shown in the drawing of this embodiment, the support portion is shown as a semicircular groove, but this is merely an example, and the concept of the present invention is not limited by the shape of the support portion.

The movement of the fall-off preventing member 100 and the moving unit 200 is related to the pressing device 300 and the pressing device driving structure 400. Therefore, the pressing device 300 and the pressing device driving structure 400 will be described below.

The pressing device 300 includes a pressing portion 310 and a pressing device moving structure 320. The pressing portion 310 is configured to be capable of selectively applying pressure to the lever portion 120 of the anti-falling member 100 by a pressing device driving structure 400 to be described later. In order to apply pressure to the lever portion 120, the pressing portion 310 needs to be moved to a position corresponding to the lever portion 120. To this end, the pressing device moving structure 320 moves the pressing portion 310 to a position corresponding to the lever portion 120. For example, the pressing device moving structure 320 may move the pressing portion 310 from the one side 121 of the lever portion 120 to a position separated by a predetermined distance in the Z-axis direction by moving the pressing portion 310.

Such a pressing device moving structure 320 may move the pressing portion 310 in a state where the pressing portion 310 is separated from the lever portion 120, or may move the pressing portion 310 in a state where the pressing portion 310 presses the lever portion 120.

In addition, the pressing device moving structure 320 can move the pressing portion while the pressing portion 310 presses the lever portion 120. Since such a lever portion 120 is included in the anti-falling device 30, the anti-falling device 30 can be moved in accordance with the movement of the pressing portion 310. For example, the pressing device 300 may move along the X-axis in a state where the pressing portion 310 presses the one side 121 of the lever portion 120, and the anti-falling device 30 may move along the X-axis to be between the anti-falling position and the release position mobile. At this time, the pressing portion 310 is inserted into the hole 231 of the body 230, and thus the driving force of the pressing device moving structure 320 can be transmitted to the anti-falling device 30. That is, since the hole 231 and the pressing portion 310 are connected to each other, the fall-off preventing device 30 can be moved by the pressing device 300. In this case, the pressing device 300 moves together with the body 230 of the anti-falling device 30. For example, when the pressing device 300 is driven to move in the + X direction while being coupled to the body 230, the body 230 and the pressing device 300 are moved in the + X direction together.

In addition, it is shown in the drawing according to the present embodiment that the pressing device moving structure 320 moves the pressing portion 310 on the XY plane, but this is merely an example and is not necessarily limited thereto. Also, the pressing device moving structure 320 may include, for example, a driving device such as a guide rail, a roller, and a motor that provides a driving force to the pressing portion of the pressing device configured in parallel with the guide 240, but the concept of the present invention is not necessarily limited thereto. Further, it is shown in the drawings according to the present embodiment that the pressing portion 310 includes a needle shape, but the concept of the present invention is not necessarily limited thereto.

In addition, it is shown in the drawing according to the present embodiment that the pressing device 300 is provided on the tray carrying portion 20, but this is merely an example and is not necessarily limited thereto.

The pressing device driving structure 400 can move the pressing device 300 so that the lever portion 120 is selectively pressurized by the pressing device 300. For example, the pressing device driving structure 400 may move the pressing portion 310 toward the lever portion 120 or move the pressing portion 310 in a direction away from the lever portion 120. That is, the pressing device driving structure 400 can make the pressing portion 310 closely fit with the lever portion 120 by moving the pressing portion 310 in the -Z direction, or make the pressing portion by moving the pressing portion 310 in the + Z direction. 310 is separated from the lever portion 120. The pressing device driving structure 400 may be disposed on the tray supporting portion 20. In addition, the pressing device driving structure 400 may include, for example, at least one of a piston, a motor, a guide, a roller, and a cylinder, but is not limited thereto.

The driving of the transfer device 1 according to the present embodiment can be controlled by the control section 40. For example, the control unit 40 may control the driving of the pressing device moving structure 320 and the pressing device driving structure 400. In addition, the control section 40 may be connected to a sensor (not shown) to know the state of the conveying device 1, for example, the position of the pressing device moving structure 320 and the pressing device driving structure 400 may be known through the sensor, and the tray may be confirmed 10 Whether to load on the tray transfer structure 20. Such a control unit 40 can be realized by a computing device including a microprocessor.

Next, operations and effects of the transmission device 1 having the above-mentioned structure will be described with reference to FIG. 7. FIG. 7 is a view showing an operation procedure of the transfer device of FIG. 1.

The tray 10 can be loaded onto the tray transfer structure 20 by a loading and unloading structure capable of transferring the tray 10. At this time, when the target object 2 is in a position free from the tray 10, it is necessary to change the anti-falling device 30 from the released state to the anti-falling state. Next, a process of changing the fall-off prevention device 30 from the released state to the fall-off prevention state will be described.

Referring to FIG. 7, first, the pressing device driving structure 400 is driven so that the lever portion 120 is pressurized by the pressing portion 310. If the pressing portion 310 has moved out of the position corresponding to the lever portion 120, the pressing device 300 is moved to A position corresponding to the lever portion 120. For example, the pressing device moving structure 320 moves the pressing device 300 in the XY direction, and when the moving pressing portion 310 moves to a position separated from the lever portion 120 in the + Z direction according to the movement of the pressing device 300, the pressing portion 310 and The lever portions 120 can drive the structures 400 closer to each other by the pressing device. At this time, the pressing device driving structure 400 can move the pressing portion 310 to one side 121 of the lever portion 120.

According to the driving of the pressing device driving structure 400, the pressing portion 310 presses the lever portion 120, and one side 121 of the lever portion is pushed in the −Z direction by the pressing portion 310. At this time, the lever portion 120 is rotated with the hinge 210 as the center, and the other side 122 of the lever portion 120 is moved in the + Z direction. In addition, the elastic member 220 connected between the other side 122 of the lever portion 120 and the body 230 of the mobile unit 200 is compressed. Due to the movement of the other side 122 of the lever portion 120, the fall-off prevention device 100 is switched from a fixed state to a movable state. In the case where the moving unit 200 includes the support portion 250, the fall-off prevention member 100 is separated from the support portion 250 by the movement of the other side 122 of the lever portion 120.

At this time, since the pressing device 300 is connected to the moving unit 200, the moving unit 200 moves according to the movement of the pressing device moving structure 320. For example, the pressing device moving structure 320 may move in the X direction together with the moving unit 200. In addition, since the moving unit 200 is connected to the fall-off prevention member 100, the fall-off prevention member 100 also moves together. That is, the anti-falling device 100 moves according to the movement of the pressing device 300. For example, the fall-off prevention member 100 may move in the X direction and be located on the target object 2. At this time, the fall prevention device 30 moves from the released state to the fall prevention state. In this fall-off prevention state, the fall-off prevention member 100 can prevent the target object 2 from falling off the tray 10.

After the anti-falling device 30 is moved to the anti-falling state, the pressing device 300 is moved in a direction separated from the moving unit 200 by the pressing device driving structure 400. Then, the lever portion 120 is no longer pressed by the pressing portion 310, and the other side 122 of the lever portion is pushed in the −Z direction by the elastic member 220. At this time, the lever portion 120 rotates with the hinge 210 as the center, and one side 121 of the lever portion 120 moves in the + Z direction. Due to the movement of the other side 122 of the lever portion 120, the fall-off preventing member 100 is in a state (fixed state) that is no longer moving. In a case where the moving unit 200 includes a supporting portion 250, the fall-off preventing member 100 is supported by the supporting portion 250 due to the movement of the other side 122 of the lever portion 120.

The tray supporting portion 20 moves the tray 10 to the working device 4 while preventing the target object 2 from falling off. At this time, the tray supporting portion 20 can also be rotated while the tray 10 is loaded.

In addition, after the transfer device 1 completes a predetermined job in a state where the tray 10 is loaded, the target object 2 needs to be unloaded from the tray 10. In this case, it is necessary to switch the fall prevention device 30 from the fall prevention state to the released state.

The process of transitioning from the release state to the anti-fall state is the reverse order from the transition from the anti-fall state to the release state. That is, the pressing device 300 can be moved to a position corresponding to the lever portion 120 by the driving of the pressing device moving structure 320, the pressing portion 310 and the lever portion 120 are close to each other by the pressing device driving structure 400, and the lever portion 120 is pressed by the pressing portion 310 pressure. By this pressure, the lever portion 120 rotates around the hinge 210 and the fall-off preventing member 100 is changed from a fixed state to a movable state. Then, the anti-falling member 100 is moved by the moving unit 200 moved according to the pressing device moving structure 320, and the anti-falling device 30 is moved from the anti-falling state to the released state. After the movement is completed, the pressing device 300 is separated from the moving unit 200, and the lever portion 120 is pressed by the elastic member 220. By this pressure, the lever portion 120 is rotated around the hinge 210 and the fall-off prevention device 100 is changed from a movable state to a fixed state.

In addition, the driving of the pressing device moving structure 320 and the pressing device driving structure 400 as described above can be controlled by the control section 40.

In addition, in the embodiment described above, the conveying device is shown as a conveying device for changing the position of the tray, but the concept of the present invention is not limited thereto. That is, the transfer device according to the embodiment of the present invention can also transfer without changing the position of the tray.

According to the embodiments described above, the effect that the target object can be more stably loaded on the tray when the tray is transferred is achieved. Furthermore, even when the tray is rotated or transferred at an extremely fast speed, the target object can be prevented from falling off the tray. In addition, the effect of minimizing the tray operation and the space required for transferring the tray is achieved. In addition, in the above-described embodiment, the pressing device driving structure 400 is described as moving the mobile pressing device 300, but the conveying device 1 according to the second embodiment described below may have the pressing device driving structure 400 for moving the tray 10. Next, a second embodiment will be described with reference to FIG. 8. FIG. 8 is a schematic diagram showing a tray carrying portion of a conveying apparatus according to a second embodiment of the present invention
