Description

Technical Field

[0001] The present application relates to the technical field of automatic board collecting equipment, and in particular to a high-precision small board collecting machine. Background Art

[0002] Small boards are widely used in industrial production, especially in the field of electronic manufacturing. The efficient processing of circuit boards directly affects the overall efficiency of the production line. In order to meet the high-paced needs of modern production, various types of board collectors have emerged. These devices not only improve the degree of automation, but also significantly reduce the need for manual intervention, increase production capacity while reducing labor costs, and have a profound impact on the manufacturing industry.

[0003] In the process of automatic stacking and collecting of small panels, it is usually adopted that they are transported from a high position to a low position for stacking and collection, and finally the stacked small panels are transported and collected at a low position. However, when the small panels are dropped from a high position, since the small panels are gradually transported out from a high position, the part of the small panels that first leave the high position will tilt downward under the action of gravity, causing the small panels to fall in an inclined state, thus making the small panels stacked unevenly. In addition, the small size of the small panels may even cause them to scatter. This problem needs to be solved urgently. Summary of the invention

[0004] In order to improve the neatness of small panel stacking and thereby achieve high-precision panel collection, the present application provides a high-precision small panel collection machine.

[0005] The present application provides a high-precision small plate receiving machine, which adopts the following technical solutions: A high-precision small plate collecting machine comprises a frame, on which a high-position conveying mechanism, a horizontal suspension receiving mechanism, a stacking mechanism and a low-position conveying mechanism are arranged, the high-position conveying mechanism is used for high-position conveying of small plates, the horizontal suspension receiving mechanism is located at the end of the conveying direction of the high-position conveying mechanism, horizontally suspends and receives the small plates conveyed from the high-position conveying mechanism and performs blanking operations, the low-position conveying mechanism is located at one side of the end of the high-position conveying mechanism, and the conveying plane of the low-position conveying mechanism is lower than the conveying plane of the high-position conveying mechanism, the stacking mechanism is located between the high-position conveying mechanism and the low-position conveying mechanism, and the stacking mechanism moves between the end of the high-position conveying mechanism and the head end of the low-position conveying mechanism, when the stacking mechanism moves to the end of the high-position conveying mechanism, the stacking mechanism is located directly below the horizontal suspension receiving mechanism, and when the stacking mechanism moves to the head end of the low-position conveying mechanism, the stacking mechanism transfers the stacked small plates to the low-position conveying mechanism.

[0006] By adopting the above technical solution, the frame supports the high-level conveying mechanism, the horizontal suspension receiving mechanism, the stacking mechanism and the low-level conveying mechanism. When it is necessary to stack and collect the small panels, the small panels are first conveyed in the high-level conveying mechanism. When the small panels are conveyed to the end of the high-level conveying mechanism, the horizontal suspension receiving mechanism horizontally suspends and receives the small panels conveyed from the high-level conveying mechanism. At this time, the stacking mechanism moves to the end of the high-level conveying mechanism and is located directly below the horizontal suspension receiving mechanism. Then, the blanking operation of the horizontal suspension receiving mechanism makes the small panels horizontal. When the small panels fall into the stacking mechanism, the dropping operation of multiple small panels realizes the stacking of the small panels in the stacking mechanism. When the stacking operation of the small panels in the stacking mechanism is completed, the stacking mechanism moves to the head end of the low-position conveying mechanism. At this time, the stacking mechanism transfers the stacked small panels to the low-position conveying mechanism for stacking and collecting operations. The small panels maintain a horizontal state during the falling process from a high position to a low position, which is beneficial to improving the neatness of the stacking and collecting of small panels, thereby realizing high-precision collecting. Moreover, each action of the small panels in the stacking and collecting process is clear and accurate, with a high degree of automation, which is beneficial to improving the efficiency of collecting.

[0007] Preferably, the horizontal suspension receiving mechanism includes a vacuum adsorption component, an inverted conveying component and a vacuum breaking component. The inverted conveying component is arranged on the frame and is located at the end of the conveying direction of the high-level conveying mechanism. The conveying plane of the inverted conveying component and the conveying plane of the high-level conveying mechanism are inverted. The vacuum adsorption component is arranged on the frame and is used to horizontally adsorb the small panels conveyed from the high-level conveying mechanism onto the conveying plane of the inverted conveying component. The vacuum breaking component is used to break the vacuum adsorption operation of the vacuum adsorption component.

[0008] By adopting the above technical scheme, when the small panel is conveyed out from the end of the high-position conveying mechanism, the vacuum adsorption component adsorbs the small panel upward, so that the small panel is conveyed tightly on the conveying plane of the inverted conveying component. At this time, the small panel is in a horizontal suspended state and will not fall. Then the vacuum breaking component breaks the vacuum adsorption operation of the vacuum adsorption component, and the small panel falls horizontally into the stacking mechanism for stacking, which is beneficial to improve the neatness of the stacking of the small panel in the stacking mechanism.

[0009] Preferably, the vacuum adsorption assembly includes a vacuum box and a vacuum suction pipe, the vacuum box is located above the end of the conveying direction of the high-level conveying mechanism, one end of the vacuum suction pipe is connected to the vacuum box, and the other end of the vacuum suction pipe is connected to the vacuum suction system, and an adsorption hole is opened at the bottom of the vacuum box.

[0010] By adopting the above technical solution, the vacuum suction system performs vacuum suction operation in the vacuum box through the vacuum suction tube, so that the vacuum box has an upward suction force through the suction hole. When the small panel is transported out from the end of the high-position conveying mechanism, the small panel is located at the bottom of the vacuum box, and the small panel is sucked by the suction force to prevent the small panel from falling downward.

[0011] Preferably, the inverted conveying assembly is vertically arranged around the vacuum box, and the inverted conveying assembly includes an inverted conveying belt, an inverted driving component and a plurality of inverted rollers, the plurality of inverted rollers are rotatably connected to the end corners of the vertical section of the vacuum box, the inverted conveying belt surrounds the plurality of inverted rollers, and the inverted driving component is arranged on the vacuum box to drive the inverted rollers to rotate.

[0012] By adopting the above technical solution, the small panel is sucked by the adsorption force to temporarily prevent it from falling, and the small panel is attached to the inverted conveyor belt to maintain a horizontal suspended state. The inverted driving part drives the inverted roller to rotate to drive the inverted conveyor belt to transmit, so that the entire small panel is in a horizontal state and detached from the end of the high-position conveying mechanism.

[0013] Preferably, the vacuum breaking assembly includes a baffle, a trigger and an opening and closing piece, the baffle is rotatably connected to the frame, and the baffle is located on the side of the vacuum box away from the high-level conveying mechanism, when the baffle is in a natural state, the lowest point of the baffle is lower than the conveying plane at the bottom of the inverted conveying assembly, the trigger is fixedly arranged on the frame, and the trigger is located on the side of the baffle away from the vacuum box, when the baffle rotates, the baffle touches the trigger, the trigger is electrically connected to the opening and closing piece, and the opening and closing piece is arranged inside the vacuum box for opening and closing the vacuum suction tube.

[0014] By adopting the above technical scheme, with the transmission of the inverted conveyor belt and the adsorption effect of the vacuum adsorption component, the small panel moves in a horizontal suspended state in the direction away from the end of the high-position conveying mechanism. When the baffle is in a natural state, its lowest point is lower than the conveying plane at the bottom of the inverted conveying component, so that the small panel can collide with the baffle during the suspended conveying. The baffle rotates after the collision, and the baffle touches the trigger during the rotation process. The trigger sends an electrical signal to the opening and closing part, and the opening and closing part closes the vacuum suction tube, thereby realizing the vacuum breaking operation. At this time, the small panel falls horizontally into the stacking mechanism under the action of gravity. The baffle returns to its natural state without the collision of the small panel and does not touch the trigger. At this time, the opening and closing part reopens the vacuum suction tube to facilitate the horizontal suspension receiving operation of the next small panel.

[0015] Preferably, the opening and closing member includes an opening and closing drive cylinder and a plug plate. The opening and closing drive cylinder is arranged inside the vacuum box and is used to drive the plug plate to move towards or away from the suction vacuum tube. The opening and closing drive cylinder is electrically connected to the trigger.

[0016] By adopting the above technical solution, the opening and closing drive cylinder drives the plug plate to move away from the suction vacuum tube to perform the vacuum suction operation, so that the small plate can be adsorbed and suspended on the inverted conveyor belt for conveying. When the trigger is triggered by the baffle, the trigger sends an electrical signal to the opening and closing drive cylinder, causing the opening and closing drive cylinder to drive the plug plate to move towards the suction vacuum tube and block the suction vacuum tube, thereby achieving the effect of breaking the vacuum. At this time, the small plate falls into the stacking mechanism under the action of gravity.

[0017] Preferably, the stacking mechanism includes a stacking conveyor component, a lifting component, and a transfer component. The transfer component is arranged on the frame and is used to drive the stacking conveyor component and the lifting component to reciprocate between the end of the high-level conveyor mechanism and the head of the low-level conveyor mechanism. The lifting component is arranged on the transfer component and is used to drive the stacking conveyor component to move vertically up and down. When the transfer component drives the stacking conveyor component to move to the end of the high-level conveyor mechanism, the stacking conveyor component is used to stack and receive the small plates falling from the horizontal suspension receiving mechanism. When the transfer component drives the stacking conveyor component to move to the head of the low-level conveyor mechanism, the stacking conveyor component is used to convey the stacked small plates into the low-level conveyor mechanism.

[0018] By adopting the above technical solution, during the falling and stacking process of the small plates, the transfer component first moves the stacking conveyor component and the lifting component to the end of the high-level conveyor mechanism, so that the small plates fall on the stacking conveyor component for stacking operations. At the same time, the lifting component first drives the stacking conveyor component to move vertically upward to reduce the falling height of the small plates, and gradually moves vertically downward as the small plates are stacked, which is beneficial to reducing the collision damage of the small plates during the stacking process. When the small plates are stacked on the stacking conveyor component, the transfer component transfers the stacking conveyor component to the head of the low-level conveyor mechanism, and then the stacking conveyor component conveys the stacked small plates into the low-level conveyor mechanism for the conveying and receiving operation of the small plates.

[0019] Preferably, the transfer component includes a transfer plate and a transfer drive member. The lifting component and the stacking conveyor component are arranged on the transfer plate. The transfer drive member is arranged on the frame and is used to drive the transfer plate to reciprocate between the end of the high-level conveyor mechanism and the head of the low-level conveyor mechanism.

[0020] By adopting the above technical solution, the transfer drive drives the transfer plate to reciprocate between the end of the high-level conveying mechanism and the head end of the low-level conveying mechanism, thereby driving the stacking conveying assembly and the lifting assembly arranged on the transfer plate to reciprocate between the end of the high-level conveying mechanism and the head end of the low-level conveying mechanism, so as to realize the transfer of the small panels after stacking from the end of the high-level conveying mechanism to the head end of the low-level conveying mechanism.

[0021] Preferably, the lifting assembly includes a lifting seat and a lifting drive member, the stacking conveying assembly is arranged on the lifting seat, the lifting drive member is arranged on the transfer plate for driving the lifting seat to move vertically up and down, and the transfer plate is also provided with a limit assembly for limiting the moving range of the lifting seat.

[0022] By adopting the above technical solution, the lifting drive member drives the lifting seat to move vertically up and down, thereby driving the stacking and conveying assembly set on the lifting seat to move vertically up and down. When the falling small panels need to be received and stacked, the lifting drive member first drives the lifting seat to move vertically upward to reduce the falling height of the small panels. As the small panels are continuously stacked on the stacking and conveying assembly, the lifting drive member gradually drives the lifting seat to move vertically downward to keep the falling height of the small panels consistent, and the limit assembly limits the stacking height of the small panels.

[0023] Preferably, the limit assembly includes a guide rod switch, a guide sleeve, an upper limit sensor and a lower limit presser, the guide rod switch is vertically fixedly connected to the lifting seat, the guide sleeve is fixedly connected to the transfer plate, the guide rod switch is movably inserted through the guide sleeve, the upper limit sensor and the lower limit presser are both arranged on the transfer plate, and the upper limit sensor is located above the lower limit presser, and the upper limit sensor and the lower limit presser are both electrically connected to the lifting drive component.

[0024] By adopting the above technical scheme, when the stacking and conveying assembly starts to take over the small panel, the lifting drive member drives the lifting seat to move vertically upward, and the movable sleeve connection of the guide rod switch and the guide sleeve realizes the guiding function. When the upper limit sensor cannot sense the guide rod switch, the upper limit sensor sends a signal to the lifting drive member to stop driving upward. In the process of the stacking and conveying assembly stacking the small panel, the lifting drive member drives the lifting seat to gradually move vertically downward. When the lower limit contactor touches the guide rod switch, the lower limit contactor sends a signal to the lifting drive member to stop driving downward. At this time, it indicates that the stacking operation of the small panel on the stacking and conveying assembly has been completed, and the transfer assembly can transfer the stacked small panel from the end of the high-position conveying mechanism to the head end of the low-position conveying mechanism.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up a high-position conveying mechanism, a horizontal suspension receiving mechanism, a stacking mechanism and a low-position conveying mechanism, when it is necessary to stack and collect small panels, the small panels are first conveyed in the high-position conveying mechanism. When the small panels are conveyed to the end of the high-position conveying mechanism, the horizontal suspension receiving mechanism horizontally suspends and receives the small panels conveyed from the high-position conveying mechanism. At this time, the stacking mechanism moves to the end of the high-position conveying mechanism and is located directly below the horizontal suspension receiving mechanism. Then, the falling operation of the horizontal suspension receiving mechanism causes the small panels to fall horizontally to the stacking mechanism. In the process, the blanking operation of multiple small panels realizes the stacking of small panels in the stacking mechanism. When the stacking operation of small panels in the stacking mechanism is completed, the stacking mechanism moves to the head end of the low-position conveying mechanism. At this time, the stacking mechanism transfers the stacked small panels to the low-position conveying mechanism for stacking and collecting operations. The small panels maintain a horizontal state during the falling process from a high position to a low position, which is beneficial to improving the neatness of the stacking and collecting of small panels, thereby realizing high-precision collecting. Moreover, each action of the small panels in the stacking and collecting process is clear and accurate, with a high degree of automation, which is beneficial to improving the efficiency of collecting.

[0026] 2. By setting up a vacuum adsorption component, an inverted conveying component and a vacuum breaking component, when the small panel is conveyed out from the end of the high-position conveying mechanism, the vacuum adsorption component adsorbs the small panel upward, so that the small panel is conveyed tightly on the conveying plane of the inverted conveying component. At this time, the small panel is in a horizontal suspended state and will not fall. Then the vacuum breaking component breaks the vacuum adsorption operation of the vacuum adsorption component, and the small panel falls horizontally into the stacking mechanism for stacking, which is beneficial to improve the neatness of the stacking of the small panel in the stacking mechanism.

[0027] 3. By setting up a vacuum box and a vacuum suction tube, the vacuum suction system performs a vacuum suction operation in the vacuum box through the vacuum suction tube, so that the vacuum box has an upward suction force through the suction hole. When the small panel is transported out from the end of the high-position conveying mechanism, the small panel is located at the bottom of the vacuum box, and the small panel is sucked by the suction force to prevent the small panel from falling downward.

DETAILED DESCRIPTION

[0038] The following is combined with Figures 1-9 This application is described in further detail.

[0039] The present application embodiment discloses a high-precision small plate receiving machine, referring to Figure 1, including a frame 1, on which a high-level conveying mechanism 2, a horizontal suspension receiving mechanism 3, a stacking mechanism 4 and a low-level conveying mechanism 5 are arranged. The high-level conveying mechanism 2 is used to carry out high-level horizontal conveying of small plates. The horizontal suspension receiving mechanism 3 is located at the end of the conveying direction of the high-level conveying mechanism 2 to horizontally suspend and receive the small plates transported from the high-level conveying mechanism 2 and perform a blanking operation. The low-level conveying mechanism 5 is located at one side of the end of the high-level conveying mechanism 2, and the conveying plane of the low-level conveying mechanism 5 is lower than the conveying plane of the high-level conveying mechanism 2. The stacking mechanism 4 The stacking mechanism 4 is located between the high-position conveying mechanism 2 and the low-position conveying mechanism 5, and the stacking mechanism 4 moves between the end of the high-position conveying mechanism 2 and the head end of the low-position conveying mechanism 5. When the stacking mechanism 4 moves to the end of the high-position conveying mechanism 2, the stacking mechanism 4 is located directly below the horizontal suspension receiving mechanism 3 to carry out the receiving and stacking process of the small panels from the high position to the low position. After the stacking operation of the small panels in the stacking mechanism 4 is completed, the stacking mechanism 4 moves to the head end of the low-position conveying mechanism 5, and the stacking mechanism 4 transfers the stacked small panels to the low-position conveying mechanism 5 for collecting the panels. In the process of stacking and collecting panels, it is beneficial to improve the neatness of the stacking and collecting of small panels, thereby realizing high-precision collecting of panels, and each action of the small panels in the process of stacking and collecting panels is clear and accurate, with a high degree of automation, which is beneficial to improving the efficiency of collecting panels.

[0040] Reference Figure 1 and Figure 2 The high-position conveying mechanism 2 includes a high-position conveying component 21, a deviation correction component 22, a leveling component 23 and an adjusting component 24. The high-position conveying component 21 is used for high-position conveying of small panels. The deviation correction component 22 is used for adjusting the position of small panels during high-position conveying to improve the neatness of subsequent stacking of small panels. The leveling component 23 is used for leveling small panels during high-position conveying to improve the quality of small panels. The adjusting component 24 is used for adjusting the conveying width of the high-position conveying component 21 to adapt to small panels of different specifications and sizes, thereby improving applicability.

[0041] Reference Figure 1 and Figure 2, the high-level conveying assembly 21 includes a high-level conveying frame, high-level conveying rollers 212, a high-level conveyor belt 213, and a high-level conveying driving member 214. The high-level conveying frame is disposed on the frame 1. The number of the high-level conveying rollers 212 is set to be several. Several high-level conveying rollers 212 are rotatably connected to the side wall of the high-level conveying frame, and the two high-level conveying rollers 212 at the head and tail ends of the high-level conveying frame are located on the same horizontal plane. The high-level conveyor belt 213 is wound around several high-level conveying rollers 212. The high-level conveying driving member 214 is disposed on the high-level conveying frame for driving the high-level conveying rollers 212 to rotate. In this embodiment, the high-level conveying driving member 214 adopts a driving motor to rotationally drive the high-level conveying rollers 212. It should be noted that the high-level conveying assemblies 21 are set to be two groups opposite to each other, and the two groups of high-level conveying assemblies 21 jointly support and convey the small plate members.

[0042] Referring to Figure 1 and Figure 2 , the deviation rectifying assembly 22 includes a guiding plate 221 and a deviation rectifying roller 222. The guiding plate 221 is horizontally fixed on the high-level conveying frame and is disposed along the length direction of the high-level conveyor belt 213. It is worth mentioning that the part of the guiding plate 221 at the head end of the high-level conveyor belt 213 is outwardly expanded. The deviation rectifying roller 222 is rotatably connected to the outwardly expanded part of the guiding plate 221 to guide the small plate member into the conveying position between the two groups of high-level conveying assemblies 21 and limit the high-level conveying position of the small plate member at the same time. Further, the wheel surface of the deviation rectifying roller 222 is provided with teeth to increase the friction between the rotating deviation rectifying roller 222 and the small plate member, so as to facilitate the deviation rectifying operation of the small plate member.

[0043] Referring to Figure 1 and Figure 2 , the leveling assembly 23 is disposed at the end of the high-level conveying frame. Specifically, the leveling assembly 23 includes a spring piece 231 and a pressing wheel 232. The spring piece 231 is fixedly disposed at the end of the high-level conveying frame. The pressing wheel 232 is rotatably connected to the spring piece 231, and the pressing wheel 232 is located directly above the high-level conveyor belt 213. There is a gap for the small plate member to pass between the pressing wheel 232 and the high-level conveyor belt 213. It should be noted that the gap between the pressing wheel 232 and the high-level conveyor belt 213 is slightly smaller than the thickness of the small plate member, and the spring piece 231 can elastically deform in the vertical direction to achieve the leveling operation of the surface of the small plate member. In this embodiment, the spring piece 231 is selected as an aluminum hollow spring piece 231, which has stable elasticity while ensuring structural stability.

[0044] Referring to Figure 1 and Figure 2When small panels of different sizes need to be transported, the adjustment component 24 adjusts the distance between the two groups of high-position conveying components 21. Specifically, the adjustment component 24 includes a support plate 241, a guide rod 242, an adjustment roller 243, an adjustment belt 244 and an adjustment drive 245. The support plate 241 is fixed on the frame 1 to support the guide rod 242, the adjustment roller 243, the adjustment belt 244 and the adjustment drive 245. The guide rod 242 is horizontally fixedly connected to the support plate 241, the guide rod 242 is perpendicular to the conveying direction of the high-position conveyor belt 213, and the high-position conveyor frame is movably sleeved on the guide rod 242, the adjustment roller 243 is rotatably connected to the support plate 241, and the adjustment belt 244 is wrapped around the adjustment roller 243, the length direction of the adjustment belt 244 is parallel to the guide rod 242, the high-position conveyor frame is fixed on the adjustment belt 244, and the adjustment drive 245 is fixedly arranged on the support plate 241 for driving the adjustment roller 243 to rotate. In this embodiment, the adjustment drive 245 also adopts a driving motor to drive the rotation of the adjustment roller 243. The adjusting driving member 245 drives the adjusting roller 243 to rotate, the adjusting roller 243 drives the adjusting belt 244 to transmit, and the adjusting belt 244 drives the two high-position conveying frames to move toward or away from each other, thereby realizing the adjustment of the conveying size.

[0045] Reference Figure 3 and Figure 4 When the small plate is transported to the end of the high-position conveying mechanism 2, the horizontal suspension receiving mechanism 3 horizontally receives the small plate and drops the small plate in a horizontal state vertically downward to improve the stability and accuracy of the stacking of the small plate. Specifically, the horizontal suspension receiving mechanism 3 includes a vacuum adsorption component 31, an inverted conveying component 32 and a vacuum breaking component 33. The inverted conveying component 32 is arranged on the frame 1 and is located at the end of the conveying direction of the high-position conveying mechanism 2. The conveying plane of the inverted conveying component 32 is inverted with the conveying plane of the high-position conveying mechanism 2. It should be noted that in the high-position conveying mechanism 2, the small plate is above the conveying plane, and in the inverted conveying component 32, the small plate is below the conveying plane. The vacuum adsorption component 31 is arranged on the frame 1 to horizontally adsorb the small plate transported from the high-position conveying mechanism 2 to the conveying plane of the inverted conveying component 32, and the vacuum breaking component 33 is used to break the vacuum adsorption operation of the vacuum adsorption component 31.

[0046] Reference Figure 3 and Figure 4, the vacuum adsorption assembly 31 includes a vacuum box 311 and a vacuum suction pipe 312. The vacuum box 311 is fixedly arranged on the frame 1 and above the end of the high-position conveying mechanism 2 in the conveying direction. In this embodiment, the vacuum box 311 is arranged in a rectangular closed frame shape. The vacuum suction pipe 312 is located above the vacuum box 311 and one end of the vacuum suction pipe 312 is communicated with the vacuum box 311. The other end of the vacuum suction pipe 312 is connected to the vacuum suction system. At the same time, adsorption holes are opened at the bottom of the vacuum box 311. The vacuum suction system, the vacuum suction pipe 312 and the vacuum box 311 cooperate to generate an upward adsorption force at the position where the adsorption holes are opened at the bottom of the vacuum box 311 to adsorb the small plate parts conveyed from the high-position conveying mechanism 2, so that the small plate parts will not fall immediately after being conveyed out of the high-position conveying mechanism 2.

[0047] Refer to Figure 3 and Figure 4 , in order to enable the vacuum-breaking operation of the vacuum-breaking assembly 33 to make the small plate parts fall immediately, the vacuum adsorption assembly 31 does not directly adsorb the small plate parts on the bottom of the vacuum box 311, but adsorbs the small plate parts in the inverted conveying assembly 32. The inverted conveying assembly 32 is vertically arranged around the vacuum box 311. Specifically, the inverted conveying assembly 32 includes an inverted conveyor belt 321, an inverted driving member 322 and several groups of inverted rollers 323. Several groups of inverted rollers 323 are respectively rotatably connected to the four end corners of the vertical cross-section of the vacuum box 311. The inverted conveyor belt 321 is wound around several groups of inverted rollers 323. The inverted driving member 322 is arranged on the vacuum box 311 to drive the inverted rollers 323 to rotate. In this embodiment, the inverted driving member 322 also adopts a driving motor to drive.

[0048] After the small plate parts are conveyed out from the end of the high-position conveying mechanism 2, under the cooperation of the vacuum adsorption assembly 31 and the inverted conveying assembly 32, the small plate parts are horizontally suspended and conveyed on the inverted conveyor belt 321.

[0049] Refer to Figure 5 and Figure 6, the vacuum-breaking assembly 33 includes a baffle 331, a trigger 332, and an opening / closing member 333. The baffle 331 is rotatably connected to the frame 1, and the baffle 331 is located on the side of the vacuum chamber 311 away from the high-level conveying mechanism 2. When the baffle 331 is in the natural state, the baffle 331 hangs vertically and the lowest point of the baffle 331 is lower than the conveying plane at the bottom of the inverted conveying assembly 32. The trigger 332 is fixedly arranged on the frame 1, and the trigger 332 is located on the side of the baffle 331 away from the vacuum chamber 311. When the baffle 331 rotates towards the trigger 332, the baffle 331 touches the trigger 332. The trigger 332 is electrically connected to the opening / closing member 333. The opening / closing member 333 is arranged inside the vacuum chamber 311 for opening and closing the suction vacuum tube 312. As the small plate is conveyed on the inverted conveyor belt 321, the small plate collides with the baffle 331 to cause the baffle 331 to rotate towards the trigger 332. When the baffle 331 touches the trigger 332, the trigger 332 sends an electrical signal to the opening / closing member 333, and the opening / closing member 333 closes the suction vacuum tube 312, so that no adsorption force is generated at the bottom of the vacuum chamber 311, and the small plate falls downward in a horizontal state under its own gravity.

[0050] Refer to Figure 5 and Figure 6 , the opening / closing member 333 includes an opening / closing driving cylinder 3331 and a plug plate 3332. The opening / closing driving cylinder 3331 is vertically and fixedly arranged inside the vacuum chamber 311 for driving the plug plate 3332 to move towards or away from the suction vacuum tube 312. The opening / closing driving cylinder 3331 is electrically connected to the trigger 332. When the baffle 331 does not touch the trigger 332, the piston rod of the opening / closing driving cylinder 3331 contracts to drive the plug plate 3332 away from the suction vacuum tube 312. At this time, an adsorption force is generated at the position of the adsorption hole at the bottom of the vacuum chamber 311. When the baffle 331 touches the trigger 332, the piston rod of the opening / closing driving cylinder 3331 extends to drive the plug plate 3332 close to the suction vacuum tube 312 and close it. At this time, no adsorption force is generated at the position of the adsorption hole at the bottom of the vacuum chamber 311, so that the small plate drops.

[0051] Refer to Figure 7 and Figure 8When the small plate falls, the stacking mechanism 4 has moved to the falling position of the small plate, and the stacking mechanism 4 receives and stacks the small plate. Specifically, the stacking mechanism 4 includes a stacking conveying assembly 41, a lifting assembly 42 and a transfer assembly 43. The transfer assembly 43 is arranged on the frame 1 to drive the stacking conveying assembly 41 and the lifting assembly 42 to reciprocate between the end of the high-position conveying mechanism 2 and the head end of the low-position conveying mechanism 5. The lifting assembly 42 is arranged on the transfer assembly 43 to drive the stacking conveying assembly 41 to move vertically up and down. When the transfer assembly 43 drives the stacking conveying assembly 41 to move to the end of the high-position conveying mechanism 2, the stacking conveying assembly 41 is used to stack and receive the small plate that falls from the horizontal suspension receiving mechanism 3. When the transfer assembly 43 drives the stacking conveying assembly 41 to move to the head end of the low-position conveying mechanism 5, the stacking conveying assembly 41 is used to transport the stacked small plate to the low-position conveying mechanism 5.

[0052] Reference Figure 7 and Figure 8 The transfer assembly 43 includes a transfer plate 431 and a transfer drive 432. The lifting assembly 42 and the stacking conveying assembly 41 are arranged on the transfer plate 431. The transfer drive 432 is arranged on the frame 1 to drive the transfer plate 431 to reciprocate between the end of the high-position conveying mechanism 2 and the beginning of the low-position conveying mechanism 5, so as to drive the lifting assembly 42 and the stacking conveying assembly 41 to reciprocate between the end of the high-position conveying mechanism 2 and the beginning of the low-position conveying mechanism 5. In this embodiment, the transfer drive 432 is selected as a motor screw structure to drive the transfer plate 431. This is a conventional setting for driving movement and will not be described in detail here. The stacking conveying assembly 41 adopts a conventional conveying structure, which will not be elaborated here. When the stacking conveying assembly 41 is transferred to the end of the high-level conveying mechanism 2, the stacking conveying assembly 41 stops the conveying operation and performs a static receiving operation. When the stacking conveying assembly 41 is transferred to the head end of the low-level conveying mechanism 5, the end of the stacking conveying assembly 41 is docked with the head end of the low-level conveying mechanism 5, and the stacking conveying assembly 41 performs a conveying operation to transfer the stacked small panels to the low-level conveying mechanism 5 for the panel collecting operation. The low-level conveying mechanism 5 also adopts a conventional conveying structure for the conveying operation, so it will not be elaborated here.

[0053] Reference Figure 7 and Figure 8, the lifting component 42 includes a lifting seat 421 and a lifting driving member 422. The stacking and conveying component 41 is arranged on the lifting seat 421, and the lifting driving member 422 is arranged on the transfer plate 431 to drive the lifting seat 421 to move vertically up and down, so as to drive the stacking and conveying component 41 to move vertically up and down. In this embodiment, the lifting driving member 422 is selected as a motor screw structure to drive the lifting seat 421, which is a conventional setting for driving the lifting and will not be elaborated here. In addition, a limiting component 6 for limiting the up and down movement range of the lifting seat 421 is also arranged on the transfer plate 431 to limit the height of the small plate members stacked on the stacking and conveying component 41.

[0054] Referring to Figure 7 and Figure 8 , the limiting component 6 includes a guide rod switch 61, a guide sleeve 62, an upper limit inductor 63 and a lower limit pressure contactor 64. The guide rod switch 61 is vertically and fixedly connected to the bottom of the lifting seat 421, the guide sleeve 62 is fixedly connected to the side wall of the transfer plate 431, and the guide rod switch 61 is vertically movably inserted through the guide sleeve 62. The upper limit inductor 63 and the lower limit pressure contactor 64 are both fixedly arranged on the side wall of the transfer plate 431, and the upper limit inductor 63 is located above the lower limit pressure contactor 64. The upper limit inductor 63 and the lower limit pressure contactor 64 are both electrically connected to the lifting driving member 422. It should be noted that the upper limit inductor 63 is located on one side of the guide rod switch 61 and monitors the guide rod switch 61. As the lifting driving member 422 drives the lifting seat 421 to move vertically upward, when the upper limit inductor 63 does not detect the guide rod switch 61, it indicates that the lifting seat 421 has risen to the apex. This position is the position where the stacking and conveying component 41 initially receives the small plate members. The upper limit inductor 63 sends an electrical signal to the lifting driving member 422, and the lifting driving member 422 stops driving the lifting seat 421 to rise. At the same time, as the small plate members are continuously stacked on the stacking and conveying component 41, the lifting driving member 422 drives the lifting seat 421 to move downward intermittently, and the guide rod switch 61 moves downward synchronously. When the guide rod switch 61 moves downward to touch the lower limit pressure contactor 64, it indicates that the lifting seat 421 has descended to the bottom point. At this position, the conveying plane of the stacking and conveying component 41 is flush with the conveying plane of the low-position conveying mechanism 5. The lower limit pressure contactor 64 sends an electrical signal to the lifting driving member 422, and the lifting driving member 422 stops driving the lifting seat 421 to descend.

[0055] Referring to Figure 8 and Figure 9, there are two low-level conveying mechanisms 5, and the two low-level conveying mechanisms 5 are respectively arranged on the opposite sides of the end of the high-level conveying mechanism 2. The stacking conveying assemblies 41 and the lifting assemblies 42 are set as two groups that cooperate with each other. When a group of stacking conveying assemblies 41 and lifting assemblies 42 perform the operation of receiving and stacking at the end of the high-level conveying mechanism 2, the other group of stacking conveying assemblies 41 and lifting assemblies 42 perform the operation of transferring the stacked small plate members to the low-level conveying mechanism 5 at the head end of a low-level conveying mechanism 5. When the stacking conveying assemblies 41 and lifting assemblies 42 that perform the receiving and stacking operation complete the receiving and stacking operation, they are transferred to the head end of the other low-level conveying mechanism 5 for transfer operation, while the other group of stacking conveying assemblies 41 and lifting assemblies 42 are transferred to the end of the high-level conveying mechanism 2 to continue the operation of receiving and stacking small plate members. This cycle is repeated to improve the plate receiving efficiency.

[0056] The implementation principle of a high-precision small plate member receiving machine according to an embodiment of the present application is as follows: The small plate members are placed in the high-level conveying mechanism 2 for conveying. When the small plate members are conveyed out from the end of the high-level conveying mechanism 2, the vacuum adsorption assembly 31 adsorbs the small plate members on the inverted conveyor belt 321 for horizontal suspended conveying. As the small plate members are conveyed on the inverted conveyor belt 321, the small plate members collide with the baffle 331 to cause the baffle 331 to rotate in the direction close to the trigger 332. When the baffle 331 touches the trigger 332, the trigger 332 sends an electrical signal to the opening and closing driving cylinder 3331, and the piston rod of the opening and closing driving cylinder 3331 stretches to drive the plug plate 3332 to approach and seal the suction vacuum tube 312. At this time, no adsorption force is generated at the position of the adsorption hole at the bottom of the vacuum box 311, so that the small plate members fall horizontally onto the stacking conveying assembly 41. The blanking operations of multiple small plate members realize the stacking of the small plate members in the stacking conveying assembly 41. When the stacking operation of the small plate members in the stacking conveying assembly 41 is completed, the stacking mechanism 4 moves to the head end of the low-level conveying mechanism 5. At this time, the stacking mechanism 4 transfers the stacked small plate members to the low-level conveying mechanism 5 for stacking and receiving plate operation. The small plate members remain in a horizontal state during the falling process from high to low, which is beneficial to improving the neatness of the stacking and receiving of the small plate members, thereby realizing high-precision plate receiving. Moreover, each action of the small plate members during the stacking and receiving plate process is distinct and accurate, and the degree of automation is high, which is beneficial to improving the plate receiving efficiency.

[0057] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
