Description

Technical Field

[0001] The present application belongs to the technical field of silicon wafer production, and in particular relates to a stacking pushing mechanism. Background Art

[0002] When the sorting machine detects and sorts silicon wafers, it will classify and stack the silicon wafers with different test results to form multiple groups of stacked wafers with different test results. The stacked wafers also need to be packed into plastic bags and placed in packaging boxes for storage for transportation. In order to save costs, the plastic bags will not be sealed, and the bag mouth is usually folded.

[0003] Since the stack is composed of multiple silicon wafers, it is relatively heavy and the number is often relatively large. In the prior art, the bagged stack is generally pushed into the packaging box by a pushing assembly. When the pushing assembly pushes the bagged stack, it is easy to cause the bag opening to loosen. When the packaging box is subsequently sealed, the bag opening needs to be manually refolded, which results in cumbersome operation and low work efficiency. Utility Model Content

[0004] The purpose of the present application is to provide a stack pushing mechanism to solve the problem in the prior art that the bag opening is easily loosened when the pushing assembly pushes the bagged stack.

[0005] To achieve this goal, this application adopts the following technical solutions:

[0006] A stacking pushing mechanism comprises a base, a bearing platform, a sliding seat, a first driving member, a pushing member, two first supporting plates and a second driving member, wherein:

[0007] A loading platform is mounted on the base, and the loading platform is configured to carry the stacked sheets to be boxed;

[0008] The sliding seat is slidably mounted on the base along a first direction, the pushing member is mounted on one end of the sliding seat close to the bearing platform, and the first driving member is configured to drive the sliding seat to approach the bearing platform along the first direction, so as to push the stacked sheets on the bearing platform into the packaging box through the pushing member;

[0009] Two first support plates are slidably mounted on the sliding seat, the two first support plates are flush with the bearing surface of the bearing platform, and the two first support plates are configured to respectively hold up the portion of the stack protruding from the bearing platform so as to closely attach the bag opening of the stack to the bag body of the stack;

[0010] The second driving member is installed on the sliding seat, and the driving end of the second driving member is connected to the two first pallets. When the pushing member moves toward the packaging box, the second driving member is configured to drive the two first pallets to move in the opposite direction so that the first pallets are stationary relative to the stack.

[0011] The stacking pushing mechanism of the present application is first driven by the first driving member to move the sliding seat close to the bearing platform, and the first support plate and the pusher on the sliding seat will follow the sliding seat to move relative to the stacking on the bearing platform. If the first support plate moves relative to the stacking, the stacking will be driven to move, and the bag mouth is easy to loosen and disengage. Therefore, in order to avoid the first support plate from moving relative to the stacking, while the first driving member is working, the second driving member will drive the first support plate away from the bearing platform, so that the first support plate is stationary relative to the stacking, and only the pusher is close to the stacking on the bearing platform. When the pusher abuts against the stacking and the bag body, the bag mouth of the bag body will be stuck and cannot be loosened. At this time, the second driving member stops working, and the first support plate and the pusher push the stacking into the packaging box under the drive of the first driving member. When one end of the stacking enters the packaging box, the second driving member can continue to work, and finally the pusher protrudes from the first support plate to push the stacking into the packaging box. By adopting the above means, when the stacked sheets are loaded into the packaging box, the bag opening of the stacked sheets will not be loosened, thereby avoiding subsequent manual correction, reducing the burden on personnel and improving work efficiency.

[0012] Optionally, the bearing platform includes two parallel sleepers, the two sleepers point toward the packaging box, and the two sleepers are used to bear the stack, with two sides of the stack protruding from the sleepers.

[0013] Two sleepers are provided to support the laminate, so that both sides of the laminate protrude from the sleepers, so that the two first supporting plates can respectively support the parts of the laminate protruding from the supporting platform.

[0014] Optionally, the stack pushing mechanism also includes a second pallet, which is mounted on the driving end of the second driving member and is located between the two first pallets. The second pallet is flush with the two first pallets, and the second pallet is inserted into the gap between the two sleepers.

[0015] By supporting the portion of the stack between the two first support plates with the second support plate, it is possible to ensure that the middle portion of the bag opening of the stack is tightly attached to the bag body of the stack, further reducing the possibility of the bag opening loosening and detaching; by installing the second support plate on the driving end of the second driving member, it is achieved that while the first driving member is working, the second driving member will drive the second support plate away from the supporting platform, thereby achieving the state where the second support plate is stationary relative to the stack.

[0016] Optionally, the stack pushing mechanism also includes a third driving member, which is installed on the driving end of the second driving member, and the second pallet is installed on the driving end of the third driving member. The third driving member is used to drive the second pallet to move up and down to get closer to or away from the stack on the supporting platform.

[0017] The second support plate is driven to rise and fall by the third driving member, so that the second support plate can be inserted into the gap between the two sleepers, ensuring that the second support plate can smoothly lift the portion of the stack located between the two first support plates.

[0018] Optionally, a double-headed cylinder is also provided on the sliding seat and is located below the supporting platform. A first regularizing plate is provided at a first driving end of the double-headed cylinder, and a second regularizing plate is provided at a second end of the double-headed cylinder. The first regularizing plate and the second regularizing plate are respectively located on both sides of the supporting platform. The double-headed cylinder is used to drive the first regularizing plate and the second regularizing plate to move closer to or away from each other along a second direction to regularize the stacked sheets on the supporting platform. The second direction is perpendicular to the first direction in a horizontal plane.

[0019] Through the cooperation of the double-headed cylinder, the first regularizing plate and the second regularizing plate, the position of the stacked sheets on the supporting platform is regularized to ensure that the stacked sheets can be smoothly pushed into the packaging box.

[0020] Optionally, the stack pushing mechanism also includes a sliding plate, which is slidably installed on the sliding seat along a first direction, and the sliding plate is connected to the driving end of the second driving member. Two fixed blocks are slidably installed on the sliding plate along a second direction, and the two first support plates are respectively fixedly installed on the two fixed blocks. A double-headed cylinder is installed on the sliding plate to drive the two fixed blocks to move closer or away. A third regularizing plate extends upward from the outer edge of each first support plate, and the third regularizing plate is used to regularize the stacks on the supporting platform.

[0021] The sliding plate is driven to slide on the sliding seat along the first direction by the second driving member, and the two first supporting plates are driven by the double-headed cylinder to approach or move away from the stack along both sides of the stack in the first direction, so that the two first supporting plates respectively lift up the parts of the stack protruding from the supporting platform to make the bag opening of the stack close to the bag body of the stack; at the same time, a third regularizing plate is integrated on each first supporting plate, which can regularize the stack while lifting up the part of the stack protruding from the supporting platform, thereby simplifying the overall structure of the stack pushing mechanism and reducing the manufacturing cost.

[0022] Optionally, the stack pushing mechanism also includes a lifting assembly and a lifting seat. The base is mounted on the lifting seat so as to be liftable via a plurality of guide rods. The lifting assembly is mounted on the lifting seat. The lifting end of the lifting assembly is connected to the base. The lifting assembly is used to drive the base to lift and lower. Each time the lifting assembly drives the base to lift and lower a preset height, the stack on the supporting platform is flush with one of the storage spaces in the packaging box, so that the pushing piece can push the stack on the supporting platform into the corresponding storage space.

[0023] Through the cooperation of the lifting assembly and the base, the automatic lifting of the load-bearing platform is realized, and then the pushing piece can push the stacked sheets on the load-bearing platform into empty storage spaces at different heights, thereby improving the pushing efficiency of the stacked sheets.

[0024] Optionally, the stack pushing mechanism also includes a frame and a sliding assembly for carrying a lifting seat, the lifting seat is slidably installed on the frame along the second direction, the sliding assembly is installed on the lifting seat, the sliding assembly is used to drive the lifting seat to slide horizontally in the second direction, and a material receiving station and a material pushing station are provided on the sliding path of the lifting seat; the sliding assembly is configured to drive the lifting seat to move to the material receiving station to receive the stack; the sliding assembly is also configured to drive the lifting seat to move to the material pushing station to align with the packaging box, and push the stack into the packaging box.

[0025] Through the cooperation of the sliding assembly and the lifting seat, the automatic switching of the lifting seat between the material receiving station and the material pushing station is realized, so that the lifting seat can receive the stacked sheets at the material receiving station and push the stacked sheets into the packaging box at the material pushing station, thereby improving the working efficiency of the stack pushing mechanism and meeting the fast-paced operation requirements.

[0026] Optionally, a camera is installed on one side of the lifting seat. When the lifting seat is located at the material receiving station, the camera takes a picture of the packaging box corresponding to the material pushing station.

[0027] By installing a camera on the lifting seat, the camera captures the image of the storage space in the packaging box when the stack pushing mechanism receives the stack. The processor processes the image information obtained by the camera and calculates where the stack should be moved to correspond to the storage space in the packaging box after the lifting seat returns to the pushing station. The processor then adjusts the position of the stack through the sliding assembly and the lifting assembly to ensure the pushing accuracy of the stack pushing mechanism.

[0028] Optionally, there are two sets of stack pushing mechanisms, one set of stack pushing mechanisms receives the stacks while the other set of stack pushing mechanisms pushes the stacks into corresponding packaging boxes.

[0042] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] When the sorting machine detects and sorts silicon wafers, it will classify and stack the silicon wafers with different test results to form multiple groups of stacked wafers with different test results. The stacked wafers also need to be packed into plastic bags and placed in packaging boxes for storage for transportation. In order to save costs, the plastic bags will not be sealed, and the bag mouth is usually folded.

[0044] Since the stack is composed of multiple silicon wafers, it is relatively heavy and the number is often relatively large. In the prior art, the bagged stack is generally pushed into the packaging box by a pushing assembly. When the pushing assembly pushes the bagged stack, it is easy to cause the bag opening to loosen. When the packaging box is subsequently sealed, the bag opening needs to be manually refolded, which results in cumbersome operation and low work efficiency.

[0045] Embodiment 1

[0046] This application proposes a stacking pushing mechanism, please refer to Figures 1 to 3As shown, the stacking pushing mechanism proposed in the first embodiment of the present application includes a base 10, a bearing platform 11, a sliding seat 12, a first driving member 20, a pushing member 30, two first supporting plates 40 and a second driving member 21, wherein: the bearing platform 11 is installed on the base 10, and the bearing platform 11 is configured to carry the stacking 50 to be packed; the sliding seat 12 moves along the first direction ( Figure 2 The first driving member 20 is configured to drive the sliding seat 12 to approach the bearing platform 11 along the first direction, so as to push the stack 50 on the bearing platform 11 into the packaging box 51 through the pushing member 30; the two first pallets 40 are slidably mounted on the sliding seat 12, and the two first pallets 40 are flush with the bearing surface of the bearing platform 11. The two first pallets 40 are configured to respectively lift the parts of the stack 50 protruding from the bearing platform 11, so as to make the bag opening of the stack 50 close to the bag body of the stack; the second driving member 21 is mounted on the sliding seat 12, and the driving end of the second driving member 21 is connected to the two first pallets 40. When the pushing member 30 moves toward the packaging box 51, the second driving member 21 is configured to drive the two first pallets 40 to move in the opposite direction, so that the first pallets 40 are stationary relative to the stack 50.

[0047] The stacking pushing mechanism of the present application first drives the sliding seat 12 to approach the supporting platform 11 by the first driving member 20, and the first pallet 40 and the pushing member 30 on the sliding seat 12 will follow the sliding seat 12 to move relative to the stacking plate 50 on the supporting platform 11. If the first pallet 40 moves relative to the stacking plate 50, the stacking plate 50 will be driven to move, and at the same time, the bag mouth (the bag mouth of the stacking plate 50 is located on the side close to the pushing member 30 and folded to a position that fits the lower surface of the stacking plate 50) is easy to loosen and disengage. Therefore, in order to prevent the first pallet 40 from moving relative to the stacking plate 50, while the first driving member 20 is working, the second driving member 21 will drive the first pallet 40 away from the supporting platform 11, so that the first pallet 40 is stationary relative to the stacking plate 50, and only the pushing member 30 is close to the stacking plate 50 on the supporting platform 11. When the pusher 30 abuts against the stack 50 and the bag body, the bag mouth of the bag body will be stuck and cannot be loosened. At this time, the second driving member 21 stops working, and the first support plate 40 and the pusher 30 push the stack 50 into the packaging box 51 driven by the first driving member 20. After one end of the stack 50 enters the packaging box 51, the second driving member 21 can continue to work, and finally the pusher 30 protrudes from the first support plate 40 to push the stack 50 into the packaging box 51. By adopting the above means, when the stack is loaded into the packaging box, the bag mouth of the stack will not be loosened, avoiding subsequent manual correction, reducing the burden on personnel, and improving work efficiency.

[0048] As an implementation manner, the support platform 11 includes two parallel sleepers 110 , the two sleepers 110 point to the packaging box 51 , and the two sleepers 110 are used to support the stack 50 , and both sides of the stack 50 protrude from the sleepers 110 .

The second pallet 41 is flush with the two first pallets 40, and the second pallet 41 is inserted into the gap between the two sleepers 110.

[0051] By supporting the portion of the stack 50 between the two first support plates 40 with the second support plate 41, it is possible to ensure that the middle portion of the bag opening of the stack 50 is tightly attached to the bag body of the stack 50, further reducing the possibility of the bag opening loosening and detaching; by installing the second support plate 41 on the driving end of the second driving member 21, it is achieved that while the first driving member 20 is working, the second driving member 21 will drive the second support plate 41 away from the supporting platform 11, thereby achieving the second support plate 41 being stationary relative to the stack 50.

[0052] As an embodiment, the stack pushing mechanism also includes a third driving member 22, which is installed on the driving end of the second driving member 21, and the second support plate 41 is installed on the driving end of the third driving member 22.

[0054] Specifically, the second driving member 21 includes a first motor 210, a screw rod 211 and a sliding member 212. The screw rod 211 is rotatably mounted on the sliding seat 12 and extends along the first direction. The fixed end of the first motor 210 is fixed on the sliding seat 12. The driving end of the first motor 210 is connected to the screw rod 211. The first motor 210 drives the screw rod 211 to rotate along its own axis. The sliding member 212 is mounted on the screw rod 211 through a screw nut. The sliding member 212 can be slidably mounted on the sliding seat 12 along the first direction through a sliding pair composed of a guide rail and a slider.

[0056] The second support plate 41 is driven to rise and fall by the third driving member 22 , so that the second support plate 41 can be inserted into the gap between the two sleepers 110 , ensuring that the second support plate 41 can smoothly lift the portion of the laminate 50 between the two first support plates 40 .

[0057] As an embodiment, the sliding seat 12 is further provided with a first double-headed cylinder 13 located below the bearing platform 11, a first driving end of the first double-headed cylinder 13 is provided with a first regularizing plate 14, a second end of the first double-headed cylinder 13 is provided with a second regularizing plate 15, the first regularizing plate 14 and the second regularizing plate 15 are respectively located on both sides of the bearing platform 11, and the first double-headed cylinder 13 is used to drive the first regularizing plate 14 and the second regularizing plate 15 to move along the second direction ( Figure 2 The second direction (in the Y direction) is closer to or farther away from each other to regularize the stack 50 on the carrier 11, and the second direction is perpendicular to the first direction on the horizontal plane.

[0058] Through the cooperation of the first double-headed cylinder 13, the first regularizing plate 14 and the second regularizing plate 15, the position of the stack 50 on the support platform 11 is regularized to ensure that the stack can be smoothly pushed into the packaging box.

[0059] See also Figure 1 and Figure 2 As shown, as an embodiment, the stack pushing mechanism also includes a lifting component 60 and a lifting seat 61. The base 10 is mounted on the lifting seat 61 so as to be liftable through a plurality of guide rods 62. The lifting component 60 is mounted on the lifting seat 61. The lifting end of the lifting component 60 is connected to the base 10. The lifting component 60 is used to drive the base 10 to move up and down. Each time the lifting component 60 drives the base 10 to move up and down to a preset height, the stack 50 on the carrier 11 is flush with one of the storage spaces in the packaging box 51, so that the pushing piece 30 can push the stack 50 on the carrier 11 into the corresponding storage space.

[0060] Specifically, the lifting assembly 60 includes a second electric cylinder 600 , which is vertically arranged, and a driving end of the second electric cylinder 600 is connected to the base 10 .

[0061] Through the cooperation of the lifting assembly 60 and the base 10, the automatic lifting of the support platform 11 is realized, and then the pusher 30 pushes the stack 50 on the support platform 11 into empty storage spaces at different heights, thereby improving the pushing efficiency of the stack.

A material receiving station and a material pushing station are provided on the sliding path of the lifting seat 61; the sliding assembly 64 is configured to drive the lifting seat 61 to move to the material receiving station to receive the stack; the sliding assembly 64 is also configured to drive the lifting seat 61 to move to the material pushing station to align with the packaging box 51, and push the stack 50 into the packaging box 51.

[0063] Specifically, the sliding assembly 64 includes a second motor 640 and a gear rack transmission member 641. The lifting seat 61 is installed on the frame 63 through a sliding pair consisting of a guide rail and a slider. The second motor 640 drives the lifting seat 61 to move alternately to the material receiving station or the material pushing station along the second direction on the frame 63 through the gear rack transmission member 641.

[0064] Through the cooperation of the sliding assembly 64 and the lifting seat 61, the automatic switching of the lifting seat 61 between the material receiving station and the material pushing station is realized, so that the lifting seat 61 can receive the stacked sheets at the material receiving station and push the stacked sheets into the packaging box at the material pushing station, thereby improving the working efficiency of the stack pushing mechanism and meeting the fast-paced operation requirements.

[0065] As an implementation manner, a camera 70 is installed on one side of the lifting seat 61. When the lifting seat 61 is located at the material receiving station, the camera 70 takes a picture of the packaging box corresponding to the material pushing station.

[0066] By installing a camera 70 on the lifting seat 61, the camera captures an image of the storage space in the packaging box when the stack pushing mechanism receives the stack. The processor processes the image information obtained by the camera and calculates where the stack should be moved to correspond to the storage space in the packaging box after the lifting seat 61 returns to the pushing station. Then the processor adjusts the position of the stack through the sliding component 64 and the lifting component 60 to ensure the pushing accuracy of the stack pushing mechanism.

[0067] As an implementation method, there are two sets of stack pushing mechanisms, one set of stack pushing mechanisms receives the stacks while the other set of stack pushing mechanisms pushes the stacks into the corresponding packaging box.

[0068] By setting up two sets of stacking pushing mechanisms, when one set of stacking pushing mechanisms receives stacking sheets, the other set of stacking pushing mechanisms pushes the received stacking sheets into an empty packaging box, so that the stacking operation does not need to wait, and the stacking efficiency is further improved.

[0069] Compared with the prior art, the stacking mechanism proposed in the first embodiment of the present application has the following advantages:

[0072] 3) The pushing piece can push the stacked sheets on the support table into empty storage spaces at different heights, thereby improving the pushing efficiency of the stacked sheets.

[0073] 4) The automatic switching of the lifting seat at the material receiving station and the material pushing station is realized, so that the lifting seat can receive the stacked sheets at the material receiving station and push the stacked sheets into the packaging box at the material pushing station, thereby improving the working efficiency of the stacking pushing mechanism and meeting the fast-paced operation requirements.

[0074] 5) Two sets of stacking pushing mechanisms are provided. When one set of stacking pushing mechanisms receives stacking sheets, the other set of stacking pushing mechanisms pushes the received stacking sheets into an empty packaging box, so that the stacking operation does not need to wait, further improving the stacking efficiency.

[0075] Embodiment 2

[0076] This application proposes a stacking pushing mechanism, please refer to Figure 4 As described above, the main difference between the stacking pushing mechanism proposed in the second embodiment of the present application and the first embodiment is that the design forms of the two first supporting plates 40 and the regular plate are different, and the other structures are the same. Only the parts different from the first embodiment are described in detail here:

[0077] The stacking pushing mechanism of this embodiment includes a sliding plate 213, which moves along a first direction ( Figure 4 The sliding plate 213 is connected to the driving end of the second driving member 21, and the sliding plate 213 is slidably mounted on the sliding seat 12 along the second direction ( Figure 4 Two fixed blocks 214 are slidably installed (in the Y direction), and two first support plates 40 are fixedly installed on the two fixed blocks 214 respectively. A second double-headed cylinder 215 is installed on the sliding plate 213 to drive the two fixed blocks 314 to move closer or farther away. A third regularizing plate 16 extends upward from the outer edge of each first support plate 40, and the third regularizing plate 16 is used to regularize the stacking plate 50 on the supporting platform 11.
