Description

Technical Field

[0001] This application relates to the field of semiconductor manufacturing equipment technology, specifically a buffer device and a conveyor line. Background Technology

[0002] Because semiconductor devices are small in size, numerous in number, and easily damaged, they need to be placed in batches on trays during the production process. The semiconductor devices are moved between different workstations by moving the trays between them, thus achieving batch transportation of semiconductor devices.

[0003] In actual production, it often occurs at a certain point on the production line that the pallets being conveyed need to be buffered, that is, a certain number of pallets need to be paused from being conveyed downstream. In existing technology, pallets that need to be buffered are often manually transferred from the conveyor line to the buffering device; when buffering is no longer needed, the pallets on the buffering device are then manually transferred back to the conveyor line, resulting in low automation and increased labor costs. Utility Model Content

[0004] Therefore, it is necessary to provide a buffering device and conveyor line that can automatically buffer the material trays, improve the degree of automation, and reduce labor costs to address the above problems.

[0005] A caching device, comprising:

[0006] A material blocking mechanism that can controllably block the material being conveyed on the conveying device;

[0007] A lifting mechanism includes a drive assembly and a lifting plate mounted on the drive end of the drive assembly, the drive assembly being used to drive the lifting plate to lift material blocked by the stop mechanism; and

[0008] The buffer mechanism includes a first mounting frame and a receiving assembly. The receiving assembly includes a receiving drive mounted on the first mounting frame and a receiving plate mounted on the drive end of the receiving drive. The receiving drive is used to drive the receiving plate to move to support the material lifted by the lifting plate.

[0009] In some embodiments, the receiving assemblies are configured as at least two, each of the receiving assemblies being arranged around a material interval lifted by the lifting plate.

[0010] In some embodiments, the buffer mechanism further includes a plurality of baffles, each mounted on the first mounting frame, with each baffle located above the lifting mechanism and together forming a storage bin for accommodating materials.

[0011] The drive assembly is used to drive the lifting plate to lift the material blocked by the material blocking mechanism into the stacking bin.

[0012] In some embodiments, the lifting plate has weight-reducing holes and / or weight-reducing grooves.

[0013] In some embodiments, the material blocking mechanism includes a fixed base, a material blocking drive, and a material blocking component. The material blocking drive is mounted on the fixed base, and the material blocking component is mounted on the drive end of the material blocking drive. The material blocking drive is used to drive the material blocking component to a blocking position that blocks the material on the conveying device or an obstacle position that allows the material on the conveying device to pass through.

[0014] In some embodiments, the lifting mechanism includes a second mounting frame, which includes a first fixed seat, a second fixed seat, a first guide rod, a movable seat, and a second guide rod;

[0015] The second fixed seat is located above the first fixed seat. The first guide rod is connected between the first fixed seat and the second fixed seat. The movable seat is located between the first fixed seat and the second fixed seat and has a first guide hole for the first guide rod to pass through. The second fixed seat has a second guide hole. The second guide rod passes through the second guide hole. One end of the second guide rod is connected to the movable seat. The lifting plate is installed at the other end of the second guide rod.

[0016] The drive assembly is mounted on the first fixed seat and / or the second fixed seat, and is drively connected to the movable seat.

[0017] In some embodiments, the lifting mechanism further includes a linear bearing sleeved in the second guide hole, and the second guide rod passing through the linear bearing.

[0018] In some embodiments, the drive assembly includes a lead screw, a lifting drive component, and a lead screw nut. The lead screw is rotatably connected between the first fixed seat and the second fixed seat. The lifting drive component is mounted on the first fixed seat and is drivenly connected to the lead screw. The lead screw nut is threaded onto the lead screw and is connected to the movable seat.

[0019] In some embodiments, the lifting drive is a stepper motor.

[0020] A conveyor line includes a conveying device and a buffer device as described in any of the above embodiments.

[0021] In actual use, the aforementioned buffer device and conveyor line transport trays upstream and downstream on the conveyor, passing through buffer stations one by one. When a tray passing through a buffer station needs to be buffered, firstly, the blocking mechanism is controlled to block the tray, causing it to stop at the buffer station. At this time, the tray stopped at the buffer station is supported on the conveyor and located above the lifting plate. Then, the drive assembly drives the lifting plate to move upward, thereby lifting the tray stopped at the buffer station. After the tray is lifted to a certain height, the receiving drive unit drives the receiving plate to move towards the tray until part of the receiving plate is below the tray. Then, the drive assembly drives the lifting plate to move downward and reset, ensuring that the lifted tray is supported on the receiving plate, thus achieving buffering; and also allowing the conveyor to transport other trays smoothly through the buffer station without being blocked by the lifting plate.

[0022] In this way, through the cooperation of the material blocking mechanism, the lifting mechanism and the buffering mechanism, the material trays that need to be buffered are automatically buffered above the conveying device, eliminating the need for manual handling of the material trays, greatly improving the degree of automation and reducing labor costs.

[0035] Please see Figure 1 and Figure 2 This application provides a conveyor line, including a conveying device 1 and a buffer device 2. The conveying device 1 is used to convey materials downstream, and the materials on the conveying device 1 can pass through a buffer station when conveying downstream. The buffer device 2 is arranged at the buffer station and can controllably block the materials reaching the buffer station from continuing to be conveyed downstream. It can also lift the blocked materials upward, so that the materials are separated from the conveying device 1, and can also support the lifted materials, so that the materials are buffered above the conveying device 1.

[0036] When it is not necessary to buffer the material passing through the buffer station, the buffer device 2 is controlled not to block the material, so that the material can pass through the buffer station under the conveying action of the conveying device 1 and continue to be conveyed downstream.

[0037] It should be noted that in some embodiments, the conveying device 1 may be a belt conveyor. Of course, in other embodiments, other types of conveyors, such as roller conveyors, may also be used, and this is not limited here.

[0038] It should also be noted that the material conveyed by the conveying device 1 can be a material tray A, or other components, which are not limited here. For ease of understanding, this article will use material tray A as an example.

[0039] In embodiments of this application, the buffer device 2 includes a blocking mechanism 10, a lifting mechanism 20, and a buffer mechanism 30. The blocking mechanism 10 can controllably block the material tray A being conveyed on the conveying device 1, causing the blocked material tray A to stop being conveyed downstream and remain at the buffer station. The lifting mechanism 20 includes a drive assembly 21 (see...). Figure 3 ) and lifting plate 23 (see Figure 3The lifting plate 23 is mounted on the drive end of the drive assembly 21. The drive assembly 21 is used to drive the lifting plate 23 to lift the tray A blocked by the blocking mechanism 10, so that the tray A is separated from the conveying device 1. The buffer mechanism 30 includes a first mounting frame 31 and a receiving assembly 32. The receiving assembly 32 includes a receiving drive 321 and a receiving plate 323. The receiving drive 321 is mounted on the first mounting frame 31, and the receiving plate 323 is mounted on the drive end of the receiving drive 321. The receiving drive 321 is used to drive the receiving plate 323 to move at least partially to below the tray A lifted by the lifting plate 23, so that after the lifting plate 23 descends, the tray A is supported on the receiving plate 323, preventing the tray A from descending with the lifting plate 23.

[0040] In actual use, the aforementioned buffer device 2 transports tray A upstream and downstream on the conveying device 1, passing through buffer stations one by one. When tray A needs to be buffered at a buffer station, firstly, the blocking mechanism 10 is controlled to block tray A, causing it to stop at the buffer station. At this time, tray A at the buffer station is supported on the conveying device 1 and located above the lifting plate 23. Then, the drive assembly 21 drives the lifting plate 23 to move upward, thereby lifting tray A at the buffer station. After tray A is lifted to a certain height, the receiving drive 321 drives the receiving plate 323 to move towards tray A until part of the receiving plate 323 is below tray A. Then, the drive assembly 21 drives the lifting plate 23 to move downward and reset, which on the one hand allows the lifted material tray A to be supported on the receiving plate 323, thus achieving buffering; on the other hand, it allows the conveying device 1 to transport other material trays A smoothly through the buffering station without being blocked by the lifting plate 23.

[0041] In this way, through the cooperation of the material blocking mechanism 10, the lifting mechanism 20 and the buffer mechanism 30, the material tray A that needs to be buffered is automatically buffered above the conveying device 1, eliminating the need for manual handling of the material tray A, greatly improving the degree of automation and reducing labor costs.

[0042] In the embodiments of this application, the material blocking mechanism 10 includes a fixed base 11, a material blocking drive 13, and a material blocking component 15. The material blocking drive 13 is mounted on the fixed base 11, and the material blocking component 15 is mounted on the drive end of the material blocking drive 13. The material blocking drive 13 is used to drive the material blocking component 15 to move to the material blocking position or to the clearance position. It should be noted that the movement of the material blocking component 15 between the material blocking position and the clearance position can be a translational movement, a rotational movement, or other movement methods, which are not limited here. In this embodiment, when the material blocking drive 13 drives the material blocking component 15 to move upward to the material blocking position, the material blocking component 15 can block the material tray A on the conveying device 1, causing the material tray A to stop being conveyed downstream and stop at the buffer station. When the material blocking drive 13 drives the material blocking component 15 to move downward to the clearance position, the material blocking component 15 cannot block the material tray A on the conveying device 1, allowing the material tray A on the conveying device 1 to pass through the buffer station and continue to be conveyed downstream. Alternatively, the stop drive 13 can be a cylinder.

[0043] In a specific embodiment, the material blocking mechanism 10 further includes a first sensor 17 disposed on the conveying device 1 (see...). Figure 2 The first sensor 17 is used to detect whether the tray A conveyed by the conveying device 1 has reached the buffer station. Thus, when the first sensor 17 detects tray A, it indicates that tray A has been conveyed to the buffer station by the conveying device 1. At this time, the blocking drive 13 drives the blocking member 15 from the avoidance position to the blocking position, thereby blocking the tray A that has reached the buffer station.

[0044] Please see Figure 3 and Figure 4 In the embodiments of this application, the lifting mechanism 20 includes a second mounting frame 211, and a lifting plate 23 is vertically and flexibly connected to the second mounting frame 211. A drive assembly 21 is mounted on the second mounting frame 211 and is drively connected to the lifting plate 23, so that the drive assembly 21 can drive the lifting plate 23 to extend or descend relative to the second mounting frame 211, so that the lifting plate 23 can lift the material tray A that is stationed at the buffer station.

[0045] In some embodiments, the second mounting bracket 211 includes a first fixed base 2111, a second fixed base 2112, a first guide rod 2113, a movable base 2114, and a second guide rod 2115. The second fixed base 2112 is located above the first fixed base 2111, and the first guide rod 2113 is fixedly connected between the first fixed base 2111 and the second fixed base 2112, so that the first fixed base 2111, the first guide rod 2113, and the second fixed base 2112 are fixedly connected as a whole. The movable base 2114 is located between the first fixed base 2111 and the second fixed base 2112, and has a first guide hole through which the first guide rod 2113 passes, so that the movable base 2114 can move up and down between the first fixed base 2111 and the second fixed base 2112. The first guide rod 2113 can guide the up and down movement of the movable base 2114.

[0046] A second guide hole is provided on the second fixed seat 2112, and a second guide rod 2115 passes through the second guide hole. The bottom end of the second guide rod 2115 is fixedly connected to the movable seat 2114, and the top end of the second guide rod 2115 is fixedly connected to the lifting plate 23. This allows the movable seat 2114 to drive the lifting plate 23 to move up and down through the second guide rod 2115. The second guide rod 2115 can guide the up and down movement of the lifting plate 23, greatly improving the positional accuracy of the lifting plate 23 and ensuring accurate lifting of the material tray A. The drive assembly 21 is installed on the first fixed seat 2111 and / or the second fixed seat 2112 and is connected to the movable seat 2114. This allows the drive assembly 21 to drive the movable seat 2114 to move up and down between the first fixed seat 2111 and the second fixed seat 2112. The movable seat 2114 then drives the lifting plate 23 to move up and down through the second guide rod 2115.

[0047] Furthermore, the lifting mechanism 20 also includes a linear bearing 2116, which is fitted inside the second guide hole, and a second guide rod 2115 passes through the linear bearing 2116. In this way, the lifting plate 23 is guided by the second guide rod 2115 and the linear bearing 2116, which further improves the positional accuracy of the lifting plate 23 and ensures that the material tray A can be accurately lifted.

[0048] In a specific embodiment, the drive assembly 21 includes a lead screw 2131, a lifting drive component 2132, and a lead screw nut 2133. The lead screw 2131 is rotatably connected between a first fixed seat 2111 and a second fixed seat 2112. Specifically, both ends of the lead screw 2131 are respectively mounted on the first fixed seat 2111 and the second fixed seat 2112 via bearings, allowing the lead screw 2131 to rotate relative to the first fixed seat 2111 and the second fixed seat 2112 about its own axis. The lifting drive component 2132 is mounted on the first fixed seat 2111 and is drively connected to the lead screw 2131, enabling the lifting drive component 2132 to drive the lead screw 2131 to rotate about its own axis. The lead screw nut 2133 is threaded onto the lead screw 2131 and fixedly connected to the movable seat 2114. This allows the lead screw nut 2133 to move along the axial direction (i.e., vertical direction) of the lead screw 2131 when the lead screw 2131 rotates. The lead screw nut 2133 then drives the movable seat 2114 to move up and down. The movable seat 2114 then drives the lifting plate 23 to move up and down through the second guide rod 2115.

[0049] Optionally, the lifting drive 2132 can be a stepper motor. Compared with using a servo motor, using a stepper motor for the lifting drive 2132 can significantly reduce equipment costs.

[0050] Furthermore, the drive assembly 21 also includes a drive wheel 2134, a driven wheel 2135, and a transmission belt 2136. The drive wheel 2134 is mounted on the output shaft of the lifting drive member 2132, enabling the lifting drive member 2132 to drive the drive wheel 2134 to rotate. The driven wheel 2135 is connected to the lead screw 2131, enabling the driven wheel 2135 to drive the lead screw 2131 to rotate together. The transmission belt 2136 is sleeved between the drive wheel 2134 and the driven wheel 2135, thereby enabling the drive wheel 2134 to drive the driven wheel 2135 to rotate via the transmission belt 2136. Thus, when it is necessary to drive the lifting plate 23 to move up and down, the lifting drive component 2132 drives the drive wheel 2134 to rotate. The drive wheel 2134 drives the driven wheel 2135 to rotate through the transmission belt 2136. The driven wheel 2135 drives the lead screw 2131 to rotate. The lead screw 2131 drives the lead screw nut 2133 to move up and down. The lead screw nut 2133 drives the movable seat 2114 to move up and down together. The movable seat 2114 drives the lifting plate 23 to move up and down together through the second guide rod 2115.

[0051] In a specific embodiment, the lifting plate 23 is provided with positioning pins 231, and the tray A has positioning holes. When the driving assembly 21 drives the lifting plate 23 to lift the tray A, the positioning pins 231 on the lifting plate 23 are inserted into the positioning holes on the tray A, thereby positioning the tray A and further improving the positional accuracy of the tray A. Optionally, the number of positioning pins 231 on the lifting plate 23 can be two or more, and the number of positioning holes on the tray A is the same as the number of positioning pins 231, so that each positioning pin 231 can be inserted into its corresponding positioning hole, thereby achieving the positioning of the tray A.

[0052] Specifically, in this embodiment, the lifting plate 23 has weight-reducing holes 235 and / or weight-reducing grooves. Thus, by creating weight-reducing holes 235 and / or weight-reducing grooves on the lifting plate 23, the weight of the lifting plate 23 is reduced, which helps to reduce the load on the lifting drive component 2132 and improve the positional accuracy of the lifting plate 23 during rising and falling. It is understood that the positions of the weight-reducing holes 235 and / or weight-reducing grooves need to avoid the second guide rod 2115; that is, the area on the lifting plate 23 that connects to the second guide rod 2115 cannot have weight-reducing holes 235 and / or weight-reducing grooves.

[0053] In the embodiments of this application, the receiving components 32 are configured as multiple (i.e., at least two). All receiving components 32 are arranged at intervals around the stacking bin B, such that when the material tray A is lifted into the stacking bin B by the lifting plate 23, all receiving components 32 are arranged at intervals around the material tray A, thereby the receiving drive component 321 of each receiving component 32 drives the receiving plate 323 to move until all receiving plates 323 jointly support the material tray A.

[0054] Specifically Figure 1 and Figure 5 In the illustrated embodiment, two receiving components 32 are provided, arranged opposite each other and spaced apart. Two receiving drive members 321 are used to drive the two receiving plates 323 to move closer to or further away from each other. Thus, when the two receiving drive members 321 drive the two receiving plates 323 to move further away from each other to a clearance state, the distance between the two receiving plates 323 is greater than the width of the tray A, allowing the lifting plate 23 to lift the tray A through the space between the two receiving plates 323, i.e., the two receiving plates 323 clear the lifted tray A. When the two receiving drive members 321 drive the two receiving plates 323 to move closer to each other to a receiving state, the distance between the two receiving plates 323 is less than the width of the tray A, so that after the lifting plate 23 descends, the tray A lifted by the lifting plate 23 is supported on the two receiving plates 323, i.e., the two receiving plates 323 jointly support the buffered tray A. Optionally, the receiving drive member 321 can be a cylinder.

[0055] Furthermore, a guide rail 311 is provided on the first mounting frame 31, and a slider 3231 is provided on the receiving plate 323. The slider 3231 is slidably mounted on the guide rail 311, thereby guiding the movement of the receiving plate 323 relative to the first mounting frame 31 by the movement of the slider 3231 along the guide rail 311, ensuring high movement accuracy of the receiving plate 323 and stable and reliable support for the material tray A.

[0056] Please see Figure 5 and Figure 6 In a specific embodiment, the buffer mechanism 30 further includes multiple baffles 34, all mounted on the first mounting frame 31. Each baffle 34 is located above the lifting mechanism 20 and together forms a storage bin B for accommodating the tray A. Thus, the lifting plate 23 lifts the tray A to be buffered into the storage bin B, thereby supporting the tray A using the receiving plate 323 and positioning the tray A using the baffles 34, preventing the tray A from shifting or even falling.

[0057] It should be noted that multiple material trays A can be stacked inside the material storage bin B, thereby achieving simultaneous buffering of multiple material trays A. The multiple material trays A, which are lifted into the material storage bin B by the lifting plate 23, are supported on two receiving plates 323, and the multi-layer material trays A are positioned by various baffles 34 to prevent the multi-layer material trays A from shifting or even falling.

[0058] Optionally, each baffle 34 extends longitudinally in the vertical direction. It is understood that the longer each baffle 34 is, the more material trays A can be stacked within the storage bin B. The length of each baffle 34 is not limited here, as long as the number of stackable material trays A meets the actual requirements.

[0059] Furthermore, the buffer mechanism 30 also includes a second sensor 37 mounted on the baffle 34. This second sensor 37 is used to detect the position of the pallet A (i.e., the bottom pallet A in the stacking silo B) that has been lifted by the lifting plate 23 into the stacking silo B. When the second sensor 37 detects that the bottom pallet A in the stacking silo B has reached a preset height, the lifting drive 2132 stops driving the lifting plate 23 to lift. At this time, the receiving drive 321 drives the receiving plate 323 to move into the stacking silo B, ensuring that the receiving plate 323 supports each pallet A in the stacking silo B.

[0060] It is understood that the number of second sensors 37 can be one or more, and this is not limited here. When there is only one second sensor 37, it is mounted on a baffle 34. When there are multiple second sensors 37, they can be mounted on multiple baffles 34 respectively.

[0061] The following describes the process of buffering multiple material trays A within the material storage silo B:

[0062] One or more pallets A are already buffered in the storage bin B, supported by two receiving plates 323. If more pallets A need to be buffered (i.e., the first sensor 17 detects that a pallet A needs to be buffered has reached the buffering position), firstly, the blocking mechanism 10 blocks the pallet A from reaching the buffering position; then, driven by the lifting drive 2132, the lifting plate 23 rises until it lifts the pallet A to contact the bottom of the pallets A in the storage bin B; then, the two receiving drives 321 drive the two receiving plates 323 to move away from each other until they are in a clearance state; at this point, all pallets A in the storage bin B are supported by the lifting plate 23; then, the lifting plate 23 continues... The material trays A within the storage bin B are continuously lifted until the second sensor 37 detects that the bottommost tray A within the storage bin B has reached a preset height. At this point, the height of each tray A within the storage bin B is higher than the height of the two receiving plates 323. Then, the two receiving drive units 321 drive the two receiving plates 323 to move closer to each other until the two receiving plates 323 are in a supported state. At this point, parts of the two receiving plates 323 are located at the bottom of each tray A within the storage bin B. Under the driving action of the lifting drive unit 2132, the lifting plate 23 moves downward and resets. At this time, each tray A within the storage bin B is supported on the two receiving plates 323, thus achieving the buffering of multiple trays A within the storage bin B.

[0063] In a specific embodiment, the baffle 34 is provided with a clearance groove 341 for the receiving plate 323 to enter or exit the stacking bin B, so as to ensure that the receiving plate 323 can enter the stacking bin B through the clearance groove 341, thereby supporting the material tray A in the stacking bin B.

[0064] Furthermore, baffle 34 comprises four, two of which are first baffles (i.e. Figure 5 The two baffles on the left side (34) are the middle two, and the other two are the second baffles (i.e. Figure 5 Two baffles 34 are located on the right side of the silo. Two receiving plates 323 are arranged at intervals along a predetermined direction. The two first baffles and the two second baffles are arranged opposite each other along the predetermined direction. The two first baffles have the aforementioned clearance grooves 341 on the side opposite to the two second baffles, so that the corresponding receiving plates 323 can enter or exit the stockpiling silo B through the clearance grooves 341. The two second baffles also have the aforementioned clearance grooves 341 on the side opposite to the two first baffles, so that the corresponding receiving plates 323 can enter or exit the stockpiling silo B through the clearance grooves 341.

[0065] Of course, the number of baffles 34 is not limited to four; it can be less than four (e.g., two) or more than four (e.g., six). No limitation is made here.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
