Description

Technical Field

[0001] This application belongs to the field of semiconductor manufacturing technology, and in particular relates to an automatic feeding device. Background Technology

[0002] In semiconductor manufacturing processes, labels need to be affixed to cards on the surfaces of milky boxes, crystal boxes, and crystal boats. Current semiconductor production lines typically require significant manual intervention. Before robots can pick up, transfer, and affix labels, workers must sort the labels and transport them to the robot's gripping area so the robot can accurately grasp them and perform subsequent actions. However, this method suffers from a mismatch between the human and robot's rhythm. Humans may not be able to deliver labels to the robot's gripping area in a timely and accurate manner, disrupting the overall production rhythm. Furthermore, the interaction between humans and robots increases the risk of accidents and injuries to operators. Utility Model Content

[0003] This application provides an automatic feeding device that enables automatic label feeding, achieves automated interaction with robots, and ensures overall production rhythm and safety.

[0004] This application provides an automatic feeding device, comprising a material carrier, including a housing, a lifting drive mechanism, and a lifting platform. The lifting drive mechanism is disposed within the housing, and the lifting platform is disposed on one side of the housing along the height direction and passes through the housing to connect with the lifting drive mechanism. The lifting drive mechanism can drive the lifting platform to move up and down relative to the housing along the height direction. A limiting mechanism includes an inlet, a storage space, and a feeding port that are sequentially distributed and interconnected along the height direction. The lifting platform can reciprocate along the height direction at least within the storage space between the inlet and the feeding port. A detection mechanism is disposed around the limiting mechanism corresponding to the feeding port and can detect the arrival status of the material at the feeding port. An auxiliary distributing mechanism is disposed at the feeding port and is at least partially overlapping the feeding port, and can separate the adhering material at the feeding port.

[0005] In the above automatic feeding device, the detection mechanism and the feeding port are at the same height in the vertical direction.

[0006] In the above-mentioned automatic feeding device, the lifting platform located at the feeding port and the detection mechanism are spaced apart in the horizontal direction perpendicular to the height direction and have a minimum interval distance D1, 6mm≤D1≤14mm.

[0007] In the above-mentioned automatic feeding device, the lifting platform has a detection slot, which is positioned opposite to the detection mechanism so that the detection mechanism can detect that the lifting platform is in a state of no material through the detection slot.

[0008] In the above automatic feeding device, in the horizontal direction, there is a detection distance D2 between the bottom of the detection trough and the detection mechanism, where 14mm < D2 ≤ 20mm.

[0009] The automatic feeding device described above includes a limiting mechanism comprising two storage plates, which are spaced apart in the horizontal direction to form a storage space, and each storage plate is provided with an auxiliary material distribution mechanism at the end of the feeding port.

[0010] The automatic feeding device described above includes an auxiliary material distribution mechanism comprising a fixedly connected mounting part and a material distribution part. The mounting part is connected to the storage plate, and the material distribution part is positioned facing the feeding port and is made of a soft material.

[0011] The automatic feeding device described above includes a lifting drive mechanism comprising a drive component and a transmission assembly arranged in a horizontal direction. The drive component is located outside the housing, and the transmission assembly is located inside the housing and extends in the height direction. The two ends of the transmission assembly are respectively connected to the drive component and the lifting platform.

[0012] The automatic feeding device described above includes a transmission assembly comprising a transmission screw, a transmission platform, and a transmission guide rod. Both the transmission screw and the transmission guide rod extend along the height direction. The transmission screw is connected to the driving component. The transmission platform is sleeved on the outer circumference of the transmission screw and is connected to the transmission screw. The two ends of the transmission guide rod are fixedly connected to the transmission platform and the lifting platform, respectively, and the transmission guide rod is slidably inserted through the top wall of the housing.

[0013] In the above-mentioned automatic feeding device, the material platform also has a transmission detection component located in the box. The transmission detection component includes an origin detection component and a lower limit detection component spaced apart in the height direction. The origin detection component is positioned higher than the lower limit detection component. The transmission component has a positioning component positioned opposite to the transmission detection component for positioning in cooperation with the transmission detection component.

[0014] The automatic feeding device of this application embodiment includes a material carrier, a limiting mechanism, a detection mechanism, and an auxiliary material distribution mechanism. The lifting drive mechanism of the material carrier, located inside the box, can pass through the box to drive the lifting platform in the storage space, so that the lifting platform can move the stacked materials between the inlet and the outlet, so as to move the materials to the outlet, where an external robot structure picks up and transfers the materials, thus eliminating the need for manual operation and ensuring the safety of the feeding action.

[0015] The detection mechanism located at the feeding port can detect whether there is material at the feeding port. When there is no material at the feeding port, the lifting platform raises the material to keep the feeding port always filled with material, so that the robot can pick up material from the feeding port at any time, ensuring the overall production rhythm. Furthermore, the auxiliary material distribution mechanism is located at the feeding port and at least partially overlaps with it. When the robot picks up material and removes it from the feeding port, adjacent materials may stick together, causing the robot to pick up too much material. In this case, the auxiliary material distribution mechanism can rub against the edge of the material, thereby sweeping the sticky material back to the top of the stacked material, thus avoiding disruption to the production rhythm and further ensuring the stability of the production rhythm.

[0016] Therefore, the automatic feeding device of this application can realize the automatic feeding operation of label materials and realize automated interaction with the robot, thereby ensuring the overall production rhythm and safety. Attached Figure Description

[0020] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0021] In semiconductor manufacturing processes, labels need to be affixed to cards on the surfaces of milky boxes, crystal boxes, and crystal boats. Current semiconductor production lines typically require significant manual intervention. Before robots can pick up, transfer, and affix labels, workers must sort the labels and transport them to the robot's gripping area so the robot can accurately grasp them and perform subsequent actions. However, this method suffers from a mismatch between the human and robot's rhythm. Humans may not be able to deliver labels to the robot's gripping area in a timely and accurate manner, disrupting the overall production rhythm. Furthermore, the interaction between humans and robots increases the risk of accidents and injuries to operators.

[0022] To address the aforementioned technical problems, this application provides an automatic feeding device capable of automatically feeding labels, enabling automated interaction with robots, and ensuring overall production rhythm and safety. The following is combined with... Figures 1 to 7 The automatic feeding device according to an embodiment of this application will be described below. Figure 1 and Figure 5 The storage space 2b of the automatic feeding device is full. To demonstrate the structure, only the material 5 in the feeding port 2c and the material 5 on the surface of the lifting platform 13 are shown; the material 5 in the middle is not displayed. Figure 2The middle section specifically shows the material 5 stacked in the storage space 2b.

[0023] like Figures 1 to 7 As shown, this application embodiment provides an automatic feeding device, which includes a material carrier 1, comprising a housing 11, a lifting drive mechanism 12, and a lifting platform 13. The lifting drive mechanism 12 is disposed inside the housing 11, and the lifting platform 13 is disposed on one side of the housing 11 along the height direction, and passes through the housing 11 to be connected to the lifting drive mechanism 12. The lifting drive mechanism 12 can drive the lifting platform 13 to move up and down relative to the housing 11 along the height direction. A limiting mechanism 2 includes sequentially distributed and interconnected components along the height direction. The lifting platform 13 is capable of reciprocating along the height direction within the storage space 2b between the inlet 2a and the feeding port 2c, and is located at the feed port 2c. The detection mechanism 3 is set on the periphery of the limiting mechanism 2 corresponding to the feeding port 2c and is capable of detecting the arrival status of the material 5 at the feeding port 2c. The auxiliary material distribution mechanism 4 is set at the feeding port 2c and is at least partially overlapped with the feeding port 2c. It is capable of separating the material 5 adhering to the feeding port 2c.

[0024] It should be noted that in the embodiments of this application, the height direction is the direction of gravity when the device is placed on a plane, while the horizontal direction is any direction perpendicular to the height direction.

[0025] In specific implementation, the automatic feeding device of this application embodiment includes a material platform 1, a limiting mechanism 2, a detection mechanism 3, and an auxiliary material distribution mechanism 4. The lifting drive mechanism 12 of the material platform 1, located in the box 11, can pass through the box 11 to drive the lifting platform 13 located in the storage space 2b, so that the lifting platform 13 can move the stacked material 5 between the inlet 2a and the feed inlet 2c, so as to move the material 5 to the feed inlet 2c, where the external robot structure picks up and transfers the material, thus eliminating the need for manual operation and ensuring the safety of the feeding action.

[0026] The detection mechanism 3, located at the feeding port 2c, can detect whether there is material at the feeding port 2c. When there is no material at the feeding port 2c, the lifting platform 13 raises the material, ensuring that the feeding port 2c always has material, so that the robot can pick up material from the feeding port 2c at any time, thus ensuring the overall production rhythm. Furthermore, the auxiliary material distribution mechanism 4 is located at the feeding port 2c and at least partially overlaps with it. When the robot picks up material 5 and removes it from the feeding port 2c, adjacent materials 5 may stick together, causing the robot to pick up more material than necessary. In this case, the auxiliary material distribution mechanism 4 can rub against the edge of the material 5, thereby sweeping the sticky material 5 back to the top of the stacked material 5, thus avoiding disruption of the production rhythm and further ensuring the stability of the production rhythm.

[0027] Therefore, the automatic feeding device of this application can realize the automatic feeding operation of label materials and realize automated interaction with the robot, thereby ensuring the overall production rhythm and safety.

[0028] like Figure 1 As shown in this embodiment, the inlet 2a, storage space 2b, and feed port 2c of the limiting mechanism 2 are distributed sequentially along the height direction, with the feed port 2c located at the top and the inlet 2a at the bottom. This arrangement facilitates the placement of stacked label materials within the storage space 2b. When the labels are stacked on the lifting platform 13 within the storage space 2b, the lifting platform 13 can control the topmost label in the stack to be positioned at the feed port 2c, thereby facilitating the robot's positioning and transfer operations at the feed port 2c. This eliminates the need for other devices or mechanisms to position and fix a large number of label materials, reducing the complexity and production cost of the automatic feeding device.

[0029] In this embodiment, the material carrier 1 is located on one side of the inlet 2a of the limiting mechanism 2, that is, the housing 11 and the lifting drive mechanism 12 inside the housing 11 are located below the inlet 2a in the height direction. This arrangement facilitates the connection between the lifting drive mechanism 12 and the lifting platform 13 through the top wall of the housing 11 and the inlet 2a, thereby enabling the lifting platform 13 to be lifted from bottom to top. This avoids interference between the lifting drive mechanism 12 and the feeding port 2c, which could affect the robot's material handling action, thus ensuring the overall production rhythm and the safety of automated production.

[0030] like Figure 1 As shown in the embodiment of this application, the automatic feeding device has the detection mechanism 3 and the feeding port 2c at the same height in the height direction.

[0031] In practice, the detection mechanism 3 and the feeding port 2c are positioned at the same height, which enables the detection mechanism 3 to perform real-time detection on the labels inside the feeding port 2c, that is, to detect the labels at the top of the stacked labels, thus ensuring the real-time and accuracy of material detection at the feeding port 2c.

[0032] Furthermore, when the detection mechanism 3 and the feeding port 2c are at the same height, it can be installed on the side of the limiting mechanism 2 in the horizontal direction, which not only ensures the installation stability of the detection mechanism 3, but also reduces the overall height of the automatic feeding device, thereby reducing the overall space occupied by the automatic feeding device.

[0033] In this embodiment, the detection mechanism 3 uses photoelectric detection to detect the material. When the material 5 is missing in the feed port 2c, the detection mechanism 3 cannot receive the photoelectric detection signal, thus detecting no material detection information. When the material 5 is present in the feed port 2c, the material 5 can reflect the photoelectric signal back to the detection mechanism 3 and be received by the detection mechanism 3, thus detecting present material detection information.

[0034] In some optional embodiments, the detection mechanism 3 may employ a visual inspection device, which may be installed above the limiting mechanism 2 to directly visually inspect the material 5 in the feed port 2c, thereby detecting the presence or absence of material.

[0035] like Figure 4 As shown in the embodiment of the present application, in the automatic feeding device, in the horizontal direction perpendicular to the height direction, the lifting platform 13 located at the feeding port 2c is spaced apart from the detection mechanism 3 and has a minimum interval distance D1, 6mm≤D1≤14mm.

[0036] In practical implementation, in the horizontal direction, there is a minimum interval distance D1 between the lifting platform 13 and the detection mechanism 3. This means that D1 is the distance between the nearest edge of the lifting platform 13 and the detection mechanism 3. When stacked labels are placed on the lifting platform 13, the distance between the label and the detection mechanism 3 is D1. Setting the minimum interval distance D1 between 6mm and 14mm ensures that the detection mechanism 3 will not fail to receive the detection signal due to a detection distance exceeding 14mm, nor will it cause inaccurate detection information due to a detection distance below 6mm. Therefore, within this distance range, the detection mechanism 3 can accurately detect the label loading status, further ensuring the overall production rhythm.

[0037] like Figure 1 and Figure 4 As shown in the embodiment of this application, the automatic feeding device has a lifting platform 13 with a detection groove 131. The detection groove 131 is positioned opposite to the detection mechanism 3 so that the detection mechanism 3 can detect that the lifting platform 13 is in a no-material state through the detection groove 131.

[0038] In practical implementation, when there is no material on the lifting platform 13, the lifting platform 13 can be raised to be within the feeding port 2c. The photoelectric signal emitted by the detection mechanism 3 is emitted into the detection groove 131. Because the detection groove 131 is recessed, its bottom is far from the detection mechanism 3, so the detection mechanism 3 cannot receive the returned detection signal, thus obtaining a detection structure in which the lifting platform 13 is in a material-free state. The setting structure of the detection groove 131 of the lifting platform 13 is simple, eliminating the need to add structures to the lifting platform 13 for detection or upgrade the detection mechanism 3, thereby reducing the complexity and production cost of the automatic feeding device.

[0039] like Figure 4 As shown in the embodiment of the present application, the automatic feeding device has a detection distance D2 between the bottom of the detection groove 131 and the detection mechanism 3 in the horizontal direction, where 14mm < D2 ≤ 20mm.

[0040] In practice, the minimum detection distance D2 is set to 14mm, so that the photoelectric signal emitted by the detection mechanism 3 cannot be reflected, thereby ensuring the stability of the materialless detection and avoiding erroneous detection signals; the maximum detection distance D2 is set to 20mm, so that the plate structure of the lifting platform 13 has sufficient support area, avoiding the detection slot 131 from having too large a slot area, which would result in the inability to stably support the label.

[0041] It should be noted that the detection mechanism 3, the interval distance, and the detection distance in this embodiment are all specifically set according to the size of the label in the semiconductor device. When detecting other materials 5, the detection mechanism 3 and the detection distance can also be adjusted accordingly based on the specific size of the material 5. Therefore, the minimum interval distance D1 and the detection distance D2 are not limited to the distance range set for the label in this embodiment.

[0042] like Figure 1 , Figure 2 and Figure 5 As shown in the embodiment of this application, the automatic feeding device includes a limiting mechanism 2 comprising two storage plates 21, which are spaced apart in the horizontal direction to form a storage space 2b, and each storage plate 21 is provided with an auxiliary distributing mechanism 4 at the end of the feeding port 2c.

[0043] In practice, two storage plates 21 are spaced apart horizontally, with the space between them forming the storage space 2b. The overall structure of the two storage plates 21 is relatively simple, facilitating their fixed connection to the top of the housing 11. Furthermore, the limiting mechanism 2 formed by the two storage plates 21 has open sides. When the detection mechanism 3 is located on the open side of the limiting mechanism 2, it can directly detect the material inside through the opening, improving the convenience of detection.

[0044] Each storage plate 21 is equipped with an auxiliary material distribution mechanism 4 at the end of the feeding port 2c. When the external robot drives the label in the feeding port 2c to leave the feeding port 2c, the two auxiliary material distribution mechanisms 4 on the two storage plates 21 can sweep the label on both sides of the label respectively, and separate the multiple labels stuck together at the edges on both sides, thereby ensuring that the excess labels stuck together can be completely removed from the labels picked up by the robot, and further improving the stability of the material distribution operation.

[0045] In some optional embodiments, the limiting mechanism 2 can be configured as a box structure with an opening at the top, and the feeding port 2c is located at the opening of the box. The box structure configuration facilitates auxiliary support for the stacked labels inside, preventing the labels from falling off from the sides.

[0046] like Figure 1 and Figure 4 As shown in the embodiment of the present application, the automatic feeding device includes an auxiliary material distribution mechanism 4, which includes a mounting part 41 and a material distribution part 42 that are fixedly connected. The mounting part 41 is connected to the storage plate 21, and the material distribution part 42 is disposed facing the feeding port 2c and is made of soft material.

[0047] In practice, the material distribution section 42 is connected to the top of the storage plate 21 via the mounting section 41 and is positioned facing the feeding port 2c. When the external robot transfers labels from the feeding port 2c, the labels being picked up rub against the soft material of the material distribution section 42, thereby achieving the effect of separating and separating the adhesive labels. By making the material distribution section 42 a soft structure, it is possible to avoid damaging the labels when sweeping the edges of the labels, thus affecting the final product quality.

[0048] Specifically, the material distribution section 42 is a brush structure. The brush structure is suitable for applications that sweep the edges of paper labels, making it easy to separate paper labels that are stuck together.

[0049] like Figure 3 , Figure 6 and Figure 7 As shown in the embodiment of the present application, the automatic feeding device includes a lifting drive mechanism 12 comprising a drive member 121 and a transmission assembly 122 arranged in the horizontal direction. The drive member 121 is located outside the housing 11, and the transmission assembly 122 is located inside the housing 11 and extends in the height direction. The two ends of the transmission assembly 122 are respectively connected to the drive member 121 and the lifting platform 13.

[0050] In practice, the driving component 121 and the transmission assembly 122 of the lifting drive mechanism 12 are arranged in the horizontal direction, rather than the driving component 121 being directly connected to the bottom of the transmission assembly 122. This avoids the situation where the height of the automatic feeding device as a whole is too large in the vertical direction, and makes the overall space occupied by the automatic feeding device smaller.

[0051] like Figure 3 , Figure 6 and Figure 7As shown in the embodiment of this application, the transmission component 122 is disposed inside the housing 11 and extends along the height direction, so that the bottom of the transmission component 122 can be connected to the drive component 121 and the top can be connected to the lifting platform 13, thereby realizing the transmission effect from the drive component 121 to the lifting platform 13, so that the drive component 121 can drive the lifting platform 13 on the top of the housing 11 to move up and down through the transmission component 122, and finally realize the transmission effect of changing the action mode and action direction.

[0052] The automatic feeding device of this application embodiment includes a transmission assembly 122 comprising a transmission screw 1221, a transmission platform 1222, and a transmission guide rod 1223. Both the transmission screw 1221 and the transmission guide rod 1223 extend along the height direction. The transmission screw 1221 is connected to the driving member 121 in a transmission manner. The transmission platform 1222 is sleeved on the outer peripheral surface of the transmission screw 1221 and is connected to the transmission screw 1221 in a transmission manner. The two ends of the transmission guide rod 1223 are respectively fixedly connected to the transmission platform 1222 and the lifting platform 13, and the transmission guide rod 1223 is slidably inserted through the top wall of the housing 11.

[0053] In specific implementation, the driving component 121 is connected to the transmission screw 1221 and can drive the transmission screw 1221 to rotate. The rotation of the transmission screw 1221 can drive the transmission platform 1222 sleeved on its outer circumference to move along the height direction. Since the transmission platform 1222 is connected to the lifting platform 13 through the transmission guide rod 1223, the transmission platform 1222 can drive the lifting platform 13 to move along the height direction, thereby realizing the lifting control of the material 5.

[0054] The transmission guide rod 1223 is slidably inserted through the top wall of the housing 11, so that the transmission platform 1222 can move along the extension direction of the transmission guide rod 1223 during the movement of the transmission platform 1222 in the height direction, thereby achieving the guiding effect of the transmission platform 1222 and avoiding the transmission platform 1222 from deviating during the lifting and lowering process.

[0055] In this embodiment of the application, the lifting drive mechanism 12 further includes a reversing component 123, which includes a pulley and a transmission belt. The bottom transmission ends of the drive member 121 and the transmission screw 1221 are both connected to the pulley for transmission. The transmission belt is sleeved on the outer circumferential surface of the two pulleys to transmit the rotation of the pulleys, thereby realizing the transmission of the rotational action from the drive member 121 to the transmission screw 1221.

[0056] Optionally, the reversing assembly 123 may also be composed of multiple meshing gears, with the gears at both ends respectively connected to the drive member 121 and the transmission screw 1221, thereby enabling the transmission of rotational motion from the drive member 121 to the transmission screw 1221.

[0057] like Figure 3 , Figure 6 and Figure 7 As shown in the embodiment of the present application, the automatic feeding device includes a material platform 1 with a transmission detection component 14 disposed on the box 11. The transmission detection component 14 includes an origin detection component 141 and a lower limit detection component 142 disposed at intervals in the height direction. The origin detection component 141 is disposed at a higher position than the lower limit detection component 142. The transmission component 122 has a positioning component 1224 disposed opposite to the position of the transmission detection component 14 for cooperating with the transmission detection component 14 for positioning.

[0058] In specific implementation, the transmission detection component 14 can detect the positioning component 1224 of the transmission component 122 through photoelectric detection, thereby detecting the specific height position of the transmission component 122. Specifically, when the origin detection component 141 detects the positioning component 1224, it indicates that the transmission component 122 is at the origin position in the height direction. At this time, the lifting platform 13 is at the inlet 2a, and the external device can feed materials onto the lifting platform 13. When the lower limit detection component 142 detects the positioning component 1224, it indicates that the transmission component 122 is at the lower limit position in the height direction. The detection of the lower limit position provides a lower limit warning effect for the overall position of the transmission component 122 and the lifting platform 13, preventing the transmission component 122 and the lifting platform 13 from continuing to move downward and causing damage to other components.

[0059] Specifically, the positioning element 1224 is connected to the outer periphery of the transmission platform 1222 and protrudes towards the transmission detection assembly 14. This positioning avoids interference between the positioning element 1224 and the transmission screw 1221, ensuring the stability and accuracy of transmission and limiting.

[0060] In some optional embodiments, a limiting member may be provided below the lower limit detection member 142 to limit the positioning member 1224 downward and prevent the positioning member 1224 and the transmission platform 1222 connected to the positioning member 1224 from continuing to move downward.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
