Description

Technical Field

[0001] This utility model relates to ceramic dielectric production equipment, and in particular to a large green sheet slab arrangement mechanism. Background Technology

[0002] After processing, ceramic substrate green pieces need to be collected in batches and placed in saggers before being sent to a sintering furnace for sintering. The diameters of the ceramic substrate green pieces vary. Larger diameter green pieces are usually placed flat in the saggers. Currently, the common method is to manually place each large green piece flat into the sagger. However, this manual method is cumbersome, as each step takes time, especially when processing large quantities of green pieces, resulting in long processing times and low efficiency. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a large green sheet stacking mechanism, which can continuously sort and transport large green sheets sent out after being pressed and formed by a tablet press, effectively improving stacking efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A large green sheet stacking mechanism, characterized in that it includes a frame, a discharge slide, a feeding platform, a stacking plate, at least two suction cups, and a robot arm capable of driving each suction cup to lift, move, and translate. The discharge slide, feeding platform, and stacking plate are sequentially arranged on the frame. The discharge slide gradually slopes downward from front to back. The feeding platform has at least two feeding guide channels that gradually slope downward from front to back. The stacking plate has at least two sheet receiving slots, which are arranged in a row from left to right. The number of sheet receiving slots, feeding guide channels, and suction cups are the same and correspond one-to-one. The feeding end of the discharge slide corresponds to the discharge port of the tablet press, the discharge end of the discharge slide corresponds to the feeding end of each feeding guide channel, and the discharge end of each feeding guide channel corresponds to the corresponding sheet receiving slot. The robot arm is mounted on the frame, and each suction cup is mounted on the power output end of the robot arm, with each suction cup corresponding to a corresponding sheet receiving slot.

[0006] The above definitions of "front" and "back" are based on the conveying direction of the large green billet. The side where the large green billet arrives first is called "front," and the side where the large green billet arrives later is called "back."

[0007] Typically, the width of the aforementioned feeding guide channel is matched with the diameter of the large green billet (the width of the feeding guide channel is slightly larger than the diameter of the large green billet), which allows the large green billets to be neatly arranged in the feeding guide channel from front to back.

[0008] During operation, the tablets are first compressed into large batches of green tablets by a tablet press. These large green tablets fall from the tablet press's outlet into the discharge chute, where they slide down from front to back into their respective feeding guide channels under gravity. Then, the large green tablets in the feeding guide channels slide down from front to back into their respective tablet receiving slots under gravity, aligning them horizontally in their respective slots. Next, a robotic arm lowers the suction cups, aligning each suction cup with a corresponding green tablet in its slot. The suction cups then pick up the corresponding green tablets using vacuum suction. Subsequently, the robotic arm lifts the suction cups and the picked-up green tablets to a position directly above the sagger. The suction cups then release the green tablets, placing them into the sagger. Finally, the robotic arm resets the suction cups, preparing for the next round of green tablet picking.

[0009] In a preferred embodiment, the large green billet stacking mechanism further includes a vibrator mounted on the frame, with the bottom of the discharge chute connected to the power output end of the vibrator. The vibration of the vibrator causes the large green billets in the discharge chute to vibrate and be conveyed, allowing them to slide downwards more effectively into their respective feeding guide channels.

[0010] In a preferred embodiment, the wafer feeding platform is provided with at least three strip-shaped wall panels. Each strip-shaped wall panel is equally spaced on the wafer feeding platform and perpendicular to it. Two adjacent strip-shaped wall panels and the wafer feeding platform form the wafer feeding guide channel. The two sides of the wafer feeding guide channel are limited by the two adjacent strip-shaped wall panels to ensure that the large green wafers maintain a horizontal posture in the wafer feeding guide channel and move along a predetermined path to the corresponding wafer receiving slot.

[0011] In the preferred embodiment, the wall of the wafer receiving groove gradually slopes inward from top to bottom. When the large green wafers in the wafer feeding guide channel slide down to the front edge of the wafer stacking plate, each large green wafer slides down into the wafer receiving groove from top to bottom along the groove wall of its corresponding wafer receiving groove, thus providing better guidance.

[0012] In a preferred embodiment, a vertically arranged baffle is provided on the rear edge of the sheet-laying plate. This baffle increases the rear height of each sheet-receiving slot, preventing large green sheets from falling out of the slots.

[0013] In a preferred embodiment, the large green sheet stacking mechanism further includes a sagger conveyor belt, located behind the stacking plate. The sagger cavity can typically hold multiple rows of large green sheets. Generally, the conveying direction of the sagger conveyor belt is the same as the conveying direction of the large green sheets. The frame is equipped with a first mark and a second mark that limit the position of the saggers placed on the sagger conveyor belt. The first mark is located in front of the second mark, and both the first and second marks correspond to the feed end of the sagger conveyor belt. During stacking, the sagger is placed on the sagger conveyor belt, with the front edge of the sagger corresponding to the first mark and the rear edge of the sagger corresponding to the second mark. After the sagger has stacked one row of large green sheets, the sagger conveyor belt moves one step forward, causing the sagger to move one step, so that the space in the sagger for the next row of large green sheets is positioned to accommodate them.

[0014] The specific structure of the aforementioned robotic arm generally adopts existing technology. For example, in one specific embodiment, the robotic arm includes a translation base and a suction cup frame. Each suction cup is mounted on the suction cup frame. The frame is equipped with a translation mechanism capable of driving the translation base to move forward and backward, and the translation base is equipped with a lifting mechanism capable of driving the suction cup frame to rise and fall. The translation mechanism can drive the translation base, lifting mechanism, suction cup frame, and each suction cup to move forward or backward a certain distance together. The lifting mechanism can drive the suction cup frame and each suction cup to rise or fall a certain height together. The aforementioned translation mechanism may include a translation motor. The power output shaft of the translation motor drives the translation base and its lifting mechanism, suction cup frame, and each suction cup to move forward or backward a certain distance together through a linkage mechanism, cam mechanism, or threaded transmission mechanism (the threaded transmission mechanism consists of meshing screws and nuts), etc. The aforementioned lifting mechanism may include a lifting motor. The power output shaft of the lifting motor drives the suction cup frame and each suction cup to rise or fall to a certain height together through a linkage mechanism, cam mechanism, or threaded transmission mechanism (the threaded transmission mechanism consists of meshing screws and nuts).

[0015] In another specific embodiment, the robotic arm includes a lifting frame, a translation base, and a suction cup frame. Each suction cup is mounted on the suction cup frame, which is connected to the translation base. The frame is equipped with a lifting mechanism capable of driving the lifting frame to move up and down, and the lifting frame is equipped with a translation mechanism capable of driving the translation base to move forward and backward. The lifting mechanism can cause the lifting frame, translation mechanism, translation base, suction cup frame, and each suction cup to rise or fall together to a certain height. The translation mechanism can cause the translation base, suction cup frame, and each suction cup to move forward or backward together to move a certain distance. Compared with the prior art, this utility model has the following advantages:

[0016] This large green sheet stacking mechanism utilizes gravity to automatically slide and transport the large green sheets downwards, requiring no additional power and reducing energy consumption. It can continuously sort, transport, and stack the large green sheets sent out after being pressed by the tablet press, effectively improving stacking efficiency, and the large green sheets in the sagger are arranged more neatly.

[0017] Figure 1 This is a structural schematic diagram of a specific embodiment of the present utility model.

[0018] Figure 2 yes Figure 1 Top view. Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-2 As shown, the large green sheet stacking mechanism in this embodiment includes a frame 1, a discharge slide 2, a sheet feeding platform 3, a sheet stacking plate 4, at least two suction cups 5, and a robotic arm 6 capable of driving each suction cup 5 to move up and down and translate. The discharge slide 2, the sheet feeding platform 3, and the sheet stacking plate 4 are sequentially arranged on the frame 1. The discharge slide 2 gradually slopes downward from front to back. The sheet feeding platform 3 is provided with four sheet feeding guide channels 31 that gradually slope downward from front to back. The sheet stacking plate 4 is provided with four sheet receiving slots 41, each sheet receiving slot 41 from left to right. Arranged in a row, the number of tablet receiving slots 41, tablet feeding guide slots, and suction cups 5 are the same and correspond one-to-one; the feeding end of the discharge slide 2 corresponds to the discharge port of the tablet press 7, the discharge end of the discharge slide 2 corresponds to the feeding end of each tablet feeding guide channel 31, and the discharge end of each tablet feeding guide channel 31 corresponds to the corresponding tablet receiving slot 41; the robot arm 6 is mounted on the frame 1, and each suction cup 5 is mounted on the power output end of the robot arm 6, with each suction cup 5 corresponding to the corresponding tablet receiving slot 41.

[0021] The definitions of "front" and "back" above are as follows: taking the conveying direction of the large green billet 8 as the reference, the side where the large green billet 8 arrives first is the front, and the side where the large green billet 8 arrives later is the back.

[0022] Typically, the width of the aforementioned feeding guide channel 31 is matched with the diameter of the large green blank 8 (the width of the feeding guide channel 31 is slightly larger than the diameter of the large green blank 8), which allows the large green blank 8 to be neatly arranged in the feeding guide channel 31 from front to back.

[0023] During operation, the tablets are first compressed into large batches of green tablets 8 by the tablet press 7. These green tablets 8 fall from the outlet of the tablet press 7 into the discharge chute 2. Under gravity, the large green tablets 8 gradually slide down the discharge chute 2 from front to back into the corresponding tablet feeding guide channel 31. Then, under gravity, the large green tablets 8 in the tablet feeding guide channel 31 gradually slide down the tablet feeding guide channel 31 from front to back into the corresponding tablet receiving slots 41, so that the large green tablets 8 are arranged in rows and placed flat in their respective receiving slots. Next... The robotic arm 6 lowers the suction cups 5, aligning each suction cup 5 with the corresponding large green blank 8 in the corresponding slot 41. Each suction cup 5 then picks up the corresponding large green blank 8 through vacuum adsorption. Subsequently, the robotic arm 6 raises the suction cups 5 and the large green blank 8 they have picked up, moving them directly above the sagger. Then, each suction cup 5 releases the large green blank 8 and places it into the sagger. Afterward, the robotic arm 6 resets each suction cup 5, preparing for the next operation of picking up the large green blank 8.

[0024] This large green sheet stacking mechanism also includes a vibrator 9, which is mounted on the frame 1. The bottom of the discharge chute 2 is connected to the power output end of the vibrator 9. The vibration of the vibrator 9 drives the large green sheets in the discharge chute 2 to vibrate and be conveyed, so that the large green sheets can slide down into the corresponding feeding guide channel 31 more effectively.

[0025] The feeding table 3 is equipped with five strip-shaped wall panels 32. Each strip-shaped wall panel 32 is equally spaced on the feeding table 3 and perpendicular to the feeding table 3. Two adjacent strip-shaped wall panels 32 and the feeding table 3 form the feeding guide channel 31. The two sides of the feeding guide channel 31 are limited by the two adjacent strip-shaped wall panels 32 to ensure that the large green wafers maintain a horizontal posture in the feeding guide channel 31 and move along a predetermined path to the corresponding wafer receiving slot 41.

[0026] The wall of the sheet receiving groove 41 gradually slopes inward from top to bottom. When the large green sheet in the sheet feeding guide channel 31 slides down to the front edge of the sheet dispensing plate 4, the large green sheets slide down into the sheet receiving groove 41 from top to bottom along the wall of the corresponding sheet receiving groove 41, which plays a better guiding role.

[0027] A vertically arranged baffle 42 is provided on the rear edge of the sheet-laying plate 4. The baffle 42 increases the rear height of each sheet-receiving groove 41, preventing large green blanks from falling out of the sheet-receiving groove 41.

[0028] This large green sheet stacking mechanism also includes a sagger conveyor belt 11, which is located behind the stacking plate 4. Four rows of large green sheets are placed in the cavity of the sagger 10. Typically, the conveying direction of the sagger conveyor belt 11 is the same as the conveying direction of the large green sheets. The frame 1 is equipped with a first mark 12 and a second mark 13 that limit the position of the sagger 10 placed on the sagger conveyor belt 11. The first mark 12 is located in front of the second mark 13, and both the first mark 12 and the second mark 13 correspond to the feed end of the sagger conveyor belt 11. When laying out the green blanks, the sagger 10 is placed on the sagger conveyor belt 11, so that the front edge of the sagger 10 corresponds to the first mark 12 and the rear edge of the sagger 10 corresponds to the second mark 13. After the sagger 10 has laid out a row of large green blanks, the sagger conveyor belt 11 moves one step and drives the sagger 10 to move one step, so that the space for the next row of large green blanks in the sagger 10 is in a position that can accommodate the large green blanks.
