Description

Technical Field

[0001] This invention relates to the field of mobile phone mid-plate stamping production line equipment technology, specifically to a mobile phone mid-plate stamping and conveying production line based on AI vision. Background Technology

[0002] As a core supporting equipment in the precision stamping production of mobile phone mid-plates, the stamping conveyor production line mainly undertakes key tasks such as workpiece transfer, loading and unloading of stamping stations, and process connection. The degree of automation, positioning accuracy, operational stability, and process linkage capability of the equipment directly determine the production efficiency, finished product yield, and operational safety of the entire stamping production line. At present, a large number of technical solutions for conveying and loading / unloading equipment applied to the stamping process of mobile phone mid-plates have been disclosed, such as those with publication numbers CN213445095U, CN121244753A, and CN216104790U. The aforementioned publicly disclosed patents and similar conventional stamping and conveying equipment in the industry are mainly divided into three types of operation modes: manual assistance, pure mechanical linkage, and traditional electrical control automation. Manual material handling and loading / unloading is labor-intensive, has poor positioning accuracy, and low operating efficiency. Pure mechanical structures have fixed operating modes, making it impossible to achieve synchronous material handling and unloading, thus limiting the production cycle. Traditional electrical control equipment has independent functional units, poor process linkage, high overall failure rate, and easy accumulation of errors, further restricting production efficiency. In summary, existing mobile phone mid-plate stamping conveyor equipment suffers from drawbacks such as high reliance on manual labor, slow production cycle, and insufficient operational stability, making it unable to meet the demands of modern stamping production with high volume, high efficiency, and high stability. Therefore, an AI vision-based mobile phone mid-plate stamping conveyor production line is proposed to effectively improve overall production efficiency, ensure workpiece processing accuracy and product quality, and enhance equipment operation stability and safety.

[0014] The beneficial effects of this invention are: (1) The mobile phone midplate stamping and conveying production line based on AI vision of the present invention has the pressing component and the stamping device in linkage during mold closing and mold opening. During the stamping process, it automatically provides power to the first telescopic component and the second telescopic component. Each functional unit is driven by the reciprocating process of the stamping action, eliminating multiple independent driving components and eliminating the need for additional independent electrical control and power systems.

[0016] (3) The mobile phone mid-plate stamping conveyor production line based on AI vision of the present invention has an oil storage cylinder and an atomizing nozzle connected to one end of the first cylinder. When the first sealing plate extends after the mold is opened, it automatically squeezes the stamping lubricant and atomizes and sprays it onto the workpiece to be processed. The moving plate is equipped with a sealed air chamber and an air jet plate. During the transfer of the workpiece, the compressed gas introduced by the exhaust valve pushes the air jet plate to extend and dynamically sprays airflow to clean the mold and workpiece surface, effectively removing dust and impurities, improving stamping quality and reducing the frequency of manual cleaning.

[0017] (4) The mobile phone mid-plate stamping conveyor production line based on AI vision of the present invention controls the piston plate and sliding rod movement by the change of negative pressure in the horizontal plate through the exhaust structure. The exhaust valve is triggered only when the workpiece is adsorbed and moved upward, so that the second telescopic component is depressurized and reset. The air path is kept sealed when not in operation. At the same time, when the stamping mold is closed, the pressure supply component drives the first telescopic component to retreat, so that the suction cup device is completely removed from the mold closing area, avoiding collision with the stamping structure, and realizing automatic protection between processes.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] To effectively improve overall production efficiency, ensure workpiece processing accuracy and product quality, and enhance equipment operation stability and safety, as an embodiment of the present invention, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9As shown, the mobile phone mid-plate stamping and conveying production line based on AI vision of the present invention includes a stamping device, with an electric feeding conveyor belt 1 and an electric unloading conveyor belt 2 respectively provided on both sides of the stamping device; the electric feeding conveyor belt 1 and the electric unloading conveyor belt 2 are connected to a horizontal track 3 by a bracket, and a slide block 4 is slidably installed on the track 3; a movable plate 5 is provided on one side of the slide block 4, and a first telescopic component that contracts by pressure is connected between the movable plate 5 and the slide block 4; a set of telescopic suction cup devices with AI vision detection are installed on each of the left and right sides of the movable plate 5, and the two sets of telescopic suction cup devices initially correspond to the mold closing area and the unloading area of ​​the stamping device respectively; a second telescopic component is provided between the slide block 4 and the track 3; The stamping device is equipped with a pressure supply component that supplies air when the mold is closed. The pressure supply component pipeline is connected to the first telescopic component. The first telescopic component is connected to the second telescopic component via the pressure relief valve 6. An exhaust structure for controlling the exhaust of the second telescopic component is installed on the side of the telescopic suction cup device.

[0022] In the initial state of use, the two sets of telescopic suction cup devices with AI vision detection correspond to the mold closing area and the material unloading area of ​​the stamping device, respectively, and the whole machine is in standby mode. When the stamping device performs the mold closing action and stamps the mobile phone middle plate, the stamping device synchronously drives the pressure supply component to operate. The pressure supply component outputs pressure to drive the first telescopic component to move. The first telescopic component drives the moving plate 5 and the two sets of telescopic suction cup devices mounted on the moving plate 5 to retract together, so that the telescopic suction cup devices are completely removed from the working area of ​​the stamping device, avoiding hard collision between the stamping structure and the telescopic suction cup devices during the mold closing process, and improving the safety of equipment operation. When the first telescopic component moves the moving plate 5 to its limit position, the pressure supply component continues to output pressure. The pressure medium inside the first telescopic component is delivered to the second telescopic component through the pressure relief valve 6. Under the action of pressure, the second telescopic component pushes the slide 4 to slide along the track 3. While the slide 4 moves, it simultaneously drives the moving plate 5 and the two sets of telescopic suction cups to move as a whole, so that the two sets of telescopic suction cups move to the feeding area and the stamping device mold closing area respectively, completing the pre-switching of the workstation. After the stamping process is completed, the stamping device performs the mold opening action. At this time, the pressure supply component outputs pressure in the opposite direction, driving the first telescopic component to extend forward, and once again driving the moving plate 5 and the two sets of telescopic suction cup devices to move synchronously. After the displacement is in place, the AI ​​vision detection on one side of the slide 4 identifies the current workstation position, and the AI ​​vision detection module 35 issues an instruction to control the two sets of telescopic suction cup devices to move synchronously. One set of telescopic suction cup devices adsorbs the mobile phone middle plate to be processed in the feeding area, and the other set of telescopic suction cup devices adsorbs the stamped mobile phone middle plate, and the material picking operation is completed synchronously. After the material is picked up, the exhaust structure controls the second telescopic component to release pressure and gradually reset. During the reset process of the second telescopic component, the slide 4, the moving plate 5, and the two sets of telescopic suction cups are pulled to move again, transferring the mobile phone middle plate to be processed from the loading area to the die closing area of ​​the stamping device, and at the same time transferring the stamped mobile phone middle plate to the unloading area. Then the telescopic suction cups release the suction, and the workpiece unloading and workpiece loading operations are completed respectively, realizing the simultaneous picking and unloading, which greatly improves the production cycle and overall conveying efficiency. After all the material feeding actions are completed, each mechanism returns to its initial standby position in sequence. The entire set of equipment repeats the above process with the next round of mold closing action of the stamping device, realizing fully automated cyclic operation of mobile phone middle plate stamping and loading and unloading. Each functional unit operates in conjunction with the stamping action, eliminating the need for multiple independent power and control units, simplifying the equipment structure and reducing the failure rate.

[0023] To facilitate the movement of the movable board 5, for example, such as Figure 4 , Figure 8 , Figure 9 As shown, the present invention further includes a first telescopic assembly comprising a connecting plate 7 fixed on a slide block 4, a first cylinder 8 horizontally mounted on the side of the connecting plate 7, a first sealing plate 9 slidably assembled inside the first cylinder 8, a first drive rod 10 fixed on one side of the first sealing plate 9, the outer end of the first drive rod 10 extending out of the first cylinder 8 and fixedly connected to a moving plate 5; a first one-way intake valve 11 and a pressure relief valve 6 are connected at the end of the first cylinder 8 facing the moving plate 5, the first one-way intake valve 11 is connected to a pressure supply assembly through a pipeline, and the pressure relief valve 6 is connected to a second telescopic assembly through a pipeline; a connecting joint 12 is provided at the end of the first cylinder 8 away from the moving plate 5, and the connecting joint 12 is connected to the pressure supply assembly.

[0024] In use, when the stamping device performs the mold closing operation, the pressurized gas output by the pressure supply component is delivered to the first one-way air inlet valve 11 through the pipeline, and then enters the first cylinder 8 through the first one-way air inlet valve 11; the air pressure entering the first cylinder 8 pushes the first sealing plate 9 to move, and the first sealing plate 9 simultaneously drives the first drive rod 10 to retract, and the first drive rod 10 then pulls the moving plate 5 and the telescopic suction cup device to move backward as a whole, so that the telescopic suction cup device completely exits the mold closing area of ​​the stamping device; When the first drive rod 10 retracts to the specified limit position, the pressure relief valve 6 opens, and the pressure gas continuously output by the pressure supply component continues to flow through the pressure relief valve 6 and is delivered to the inside of the second telescopic component. The second telescopic component is driven by air pressure to complete the switching action of the whole machine station, realize pressure diversion and step-by-step action, without the need for an additional electrical control switching mechanism, simplifying the control logic and reducing the equipment failure rate. After the stamping device completes the stamping process and performs the mold opening action, the pressurized gas is injected into the end of the first cylinder 8 away from the moving plate 5 through the connecting joint 12; the gas pressure on this side pushes the first sealing plate 9 to move in the opposite direction. During the reverse movement of the first sealing plate 9, the upper space of the first cylinder 8 is squeezed again. The gas in the cylinder can be transported to the inside of the second telescopic component through the pressure relief valve 6, so that the inside of the second telescopic component continuously stores high-pressure gas. The first sealing plate 9 drives the first drive rod 10 to extend outward. The first drive rod 10 simultaneously pushes the moving plate 5 and the telescopic suction cup device forward as a whole, so that the two sets of telescopic suction cup devices correspond to the stamping device mold closing area and the electric feeding conveyor belt 1 area respectively, completing the station reset, preparing for subsequent workpiece adsorption and transfer operations, ensuring smooth connection of loading and unloading processes, and improving overall production continuity.

[0025] To facilitate the driving of the telescopic suction cup device to complete the workstation change, for example, such as Figure 4 , Figure 5 As shown, the present invention also includes a second telescopic assembly comprising a telescopic cylinder 13. The cylinder end of the telescopic cylinder 13 is connected to the side of the track 3 via a fixing plate 14. The piston rod end of the telescopic cylinder 13 is fixed to the side of the slide block 4 via a plate 15. The telescopic cylinder 13 is provided with a second one-way inlet valve 16 and an outlet valve 17. The second one-way inlet valve 16 is connected to a pressure relief valve 6 via a pipeline, and the outlet valve 17 is connected to an exhaust structure via a pipeline.

[0026] During use, during the mold closing process of the stamping device, after the first drive rod 10 in the first cylinder 8 retracts to the limit position, the pressurized gas is delivered to the second one-way air inlet valve 16 through the pressure relief valve 6 and pipeline. The second one-way air inlet valve 16 enables the gas to enter the telescopic cylinder 13 in one direction, and the air pressure pushes the piston rod of the telescopic cylinder 13 to extend outward. The piston rod drives the slide block 4 to slide along the track 3 through the plate 15, and the entire machine station switching is completed synchronously. When the two sets of telescopic suction cups are aligned with the electric feeding conveyor belt 1 and the stamping device mold closing area respectively, and the corresponding workpieces are adsorbed, the exhaust structure is triggered, thereby opening the exhaust valve 17 on the telescopic cylinder 13; the pressurized gas inside the telescopic cylinder 13 is quickly discharged through the exhaust valve 17, and the telescopic cylinder 13 automatically retracts, causing the piston rod to automatically reset with the release of air pressure; during the piston rod reset process, the slide block 4 is pulled in the opposite direction by the plate 15, and the slide block 4 synchronously drives the moving plate 5 and the two sets of telescopic suction cups to complete the workstation conversion again, transferring the workpiece to be processed in the feeding area to the stamping mold closing area, and at the same time transferring the stamped workpiece to the electric unloading conveyor belt 2 area. The exhaust is triggered by mechanical linkage, without the need for additional electrical control components, simplifying the control process, and realizing the simultaneous completion of material picking and unloading, effectively improving the overall operating efficiency of the production line.

[0027] For example, such as Figure 1, Figure 2 , Figure 3 As shown, the present invention also includes a stamping device comprising a cabinet 18, on which a bottom mold 19 for supporting the mobile phone midplate workpiece is provided; a support frame 20 is fixedly connected to the upper end of the cabinet 18, an electric hydraulic cylinder 21 is vertically mounted on the top of the support frame 20, a stamping plate 22 is fixedly connected to the lower end of the electric hydraulic cylinder 21, and an upper mold stamping structure 23 is detachably installed on the bottom of the stamping plate 22.

[0028] During operation, the mobile phone mid-plate workpiece to be processed is placed on the bottom mold 19. The electric hydraulic cylinder 21 is activated, which drives the stamping plate 22 to move vertically downward. The stamping plate 22 simultaneously drives the upper mold stamping structure 23 to move downward together, so that the upper mold stamping structure 23 and the bottom mold 19 close together, completing the stamping process of the mobile phone mid-plate. The upper mold stamping structure 23 adopts a detachable design, which is convenient for replacement according to different specifications of workpieces. After the stamping operation is completed, the electric hydraulic cylinder 21 drives the stamping plate 22 and the upper mold stamping structure 23 to move upward and reset, leaving working space for the next round of loading, unloading and stamping operations, ensuring the continuous operation of the entire production line.

[0029] To facilitate providing working pressure to the first telescopic component, for example, such as Figure 4 , Figure 5 , Figure 7 As shown, the present invention also includes a pressure supply assembly comprising a vertically arranged second cylinder 24, a second sealing plate 54 being slidably fitted inside the second cylinder 24, a second drive rod 25 being fixedly connected to the second sealing plate 54, and the upper end of the second drive rod 25 being fixedly connected to the stamping plate 22; a first connecting valve 26 and a second connecting valve 27 are respectively provided at the upper and lower ends of the second cylinder 24, the second connecting valve 27 being connected to a first one-way air intake valve 11 through a pipeline, the first connecting valve 26 being connected to a connecting joint 12 on the first cylinder 8 through a pipeline, and an upper air intake valve 28 and a lower air intake valve 29 being respectively connected at the upper and lower ends of the second cylinder 24.

[0030] In use, when the stamping device performs the mold closing action, the electric hydraulic cylinder 21 drives the stamping plate 22 to move downward. The stamping plate 22 simultaneously pulls the second drive rod 25 downward. The second drive rod 25 pushes the second sealing plate 54 inside the second cylinder 24 to slide downward. The second sealing plate 54 squeezes the pressurized gas in the lower cavity of the second cylinder 24. The pressurized gas is successively transported through the second connecting valve 27 and the connecting pipeline to the first one-way air inlet valve 11, and finally sent into the first cylinder 8 to provide working pressure for the first telescopic component. The pressure output is directly completed by relying on the downward stamping action, realizing the mechanical linkage between the stamping process and the conveying process, saving additional power equipment, reducing energy consumption and failure probability. At the same time, during the downward movement of the second sealing plate 54, a negative pressure environment is formed in the upper cavity of the second cylinder 24. External gas is drawn into the upper cavity of the second cylinder 24 through the upper air inlet valve 28 to complete the air replenishment, ensuring stable air pressure circulation inside the cylinder, reserving air source for subsequent mold opening operations, and ensuring that the entire set of operations is continuous and smooth. When the stamping operation is completed, the stamping device performs the mold opening action. The electric hydraulic cylinder 21 drives the stamping plate 22 and the second drive rod 25 to reset upwards together. The second sealing plate 54 moves upwards accordingly. At this time, the outside gas enters the lower cavity of the second cylinder 24 through the lower air inlet valve 29 to complete the air replenishment. The second sealing plate 54 simultaneously squeezes the gas in the upper cavity of the second cylinder 24. The pressurized gas is transported to the connecting joint 12 of the first cylinder 8 through the first connecting valve 26 and pipeline. The pressure medium is introduced from the other end of the first cylinder 8, pushing the first sealing plate 9 and the first drive rod 10 to extend outwards in the opposite direction. This drives the moving plate 5 and the telescopic suction cup device to move to the area of ​​the electric feeding conveyor belt 1 and the mold closing area of ​​the stamping device. Through the partitioned air supply of the upper and lower cavities of the cylinder, the reciprocating drive of the first telescopic component is realized, ensuring accurate alignment of the loading and unloading stations and improving the workpiece transfer accuracy and production cycle.

[0031] For example, such as Figure 4 , Figure 5 , Figure 6 As shown, the present invention also includes a telescopic suction cup device comprising a support plate 30 fixedly installed on one side of the movable plate 5, an electric telescopic cylinder 31 installed on the top surface of the support plate 30, the piston rod end of the electric telescopic cylinder 31 extending downward through the support plate 30 and fixedly connected to a horizontal plate 32; the horizontal plate 32 has a cavity inside, and multiple sets of suction cups 33 are assembled on the bottom surface of the horizontal plate 32, all of which are connected to the cavity; a pipe joint 34 for connecting to an external negative pressure air source is provided on the outside of the horizontal plate 32. An AI vision detection module 35 is fixedly connected to one side of the slide 4. After the AI ​​vision detection module 35 identifies the workstation position, it controls the electric telescopic cylinder 31 to drive the horizontal plate 32 to rise and fall, and switches the negative pressure air source on and off according to the loading and unloading conditions to complete the adsorption and release of the workpiece; the exhaust structure is linked with the negative pressure air source to control the second telescopic component to depressurize and reset.

[0032] When in use, after the mold is opened, the first drive rod 10 extends outward, pushing the moving plate 5 and the two sets of telescopic suction cups to move, so that the two sets of telescopic suction cups correspond to the electric feeding conveyor belt 1 area and the stamping device mold closing area respectively. At this time, the AI ​​vision detection module 35 on one side of the slide 4 identifies the station position in real time and determines that the feeding station has completed the feeding of the workpiece. Relying on AI vision positioning to replace manual judgment, the station recognition accuracy is greatly improved and the problem of workpiece adsorption misalignment is avoided. After the AI ​​vision inspection module 35 accurately identifies the workpiece in place, it issues a control command to drive the electric telescopic cylinder 31 on the support plate 30 to extend downwards, causing the horizontal plate 32 to move downwards as a whole. The suction cup 33 on the bottom surface of the horizontal plate 32 approaches the workpiece, and the pipe joint 34 on the outside of the horizontal plate 32 is connected to an external negative pressure air source. The internal cavity of the horizontal plate 32 forms a negative pressure. The two sets of suction cups 33 respectively adsorb the mobile phone middle plate to be processed on the electric feeding conveyor belt 1 and the mobile phone middle plate that has been processed in the mold closing area of ​​the stamping device. The workpiece is fixed by negative pressure adsorption, which is stable and will not damage the surface of the workpiece, and is suitable for the precision processing requirements of mobile phone middle plates. After the workpiece is adsorbed, the electric telescopic cylinder 31 drives the horizontal plate 32 to reset upward. During the upward movement of the horizontal plate 32, the exhaust structure is activated and the air passage of the second telescopic component is opened, so that the gas inside the telescopic cylinder 13 is discharged and gradually reset. During the reset process of the telescopic cylinder 13, the slide 4, the moving plate 5 and the two sets of telescopic suction cup devices are moved as a whole, and the adsorbed workpiece to be processed is transferred to the mold closing area of ​​the stamping device, and the processed workpiece is transferred to the area of ​​the electric unloading conveyor belt 2. After the two sets of telescopic suction cup devices arrive at the unloading station, the AI ​​vision detection module 35 completes the station recognition and drives the electric telescopic cylinder 31 to move the horizontal plate 32 downward. At the same time, the system cuts off the negative pressure air source, the negative pressure in the cavity disappears, the suction cup 33 releases the adsorption of the workpiece, the workpiece to be processed falls into the mold closing area, and the processed workpiece falls into the unloading conveyor belt. The loading and unloading operations are completed simultaneously, the process is connected smoothly, and the production cycle of the entire production line is effectively improved. After the material feeding operation is completed, the electric telescopic cylinder 31 drives the horizontal plate 32 to return to its original position. At this time, the negative pressure air source is disconnected, the cavity of the horizontal plate 32 returns to normal pressure, and the exhaust structure closes automatically. The air passage of the second telescopic component remains sealed, realizing the linkage and self-locking between the negative pressure on / off and the exhaust structure. The exhaust action is triggered only when the device moves upward with negative pressure. In the non-working state, the air passage is sealed and leak-proof, ensuring the stable operation of the entire pneumatic system, reducing the failure rate, and the equipment enters the standby state, waiting for the next cycle of operation.

[0033] To facilitate control of the opening and closing of the exhaust valve 41, for example, such as Figure 5 , Figure 6 , Figure 10As shown, the present invention also includes an exhaust structure comprising a fixed cylinder 36 horizontally fixed to one side of a horizontal plate 32, the interior of the fixed cylinder 36 being connected to the cavity of the horizontal plate 32; a piston plate 37 is sealed and slidably assembled inside the fixed cylinder 36, a sliding rod 38 is fixedly connected to the side of the piston plate 37 away from the horizontal plate 32, a return spring 39 is fixedly connected between the piston plate 37 and the inner wall of the fixed cylinder 36, the sliding rod 38 extends out of the fixed cylinder 36, a positioning hole 40 is provided on the sliding rod 38, an exhaust valve 41 is installed at the lower part of the support plate 30, in the initial state the valve stem 42 of the exhaust valve 41 is located in the positioning hole 40 on the sliding rod 38, and the exhaust valve 41 is connected to the exhaust valve 17 of the telescopic cylinder 13 through a pipeline.

[0034] When in use, when the two sets of telescopic suction cup devices are located in the feeding area and the mold closing area respectively, the AI ​​vision detection module 35 drives the electric telescopic cylinder 31 to move the horizontal plate 32 downward. The cavity inside the horizontal plate 32 is connected to the negative pressure air source, and a negative pressure is formed inside the fixed cylinder 36. Under the action of negative pressure suction, the piston plate 37 slides towards the horizontal plate 32, and the return spring 39 is stretched synchronously to complete the energy storage. The piston plate 37 drives the sliding rod 38 to move together. The positioning hole 40 on the sliding rod 38 is misaligned with the valve stem 42 of the exhaust valve 41. The exhaust valve 41 remains closed, and the air passage of the second telescopic component is in a sealed and pressure-maintaining state. After the workpiece is adsorbed, the electric telescopic cylinder 31 drives the horizontal plate 32 to rise. When the horizontal plate 32 moves to the designated position, the sliding rod 38 and the valve stem 42 of the exhaust valve 41 squeeze each other, and the exhaust valve 41 is triggered to open. The gas inside the telescopic cylinder 13 is discharged outward through the exhaust valve 17 and the pipeline. The telescopic cylinder 13 gradually resets, driving the slide 4 and the moving plate 5 to complete the station switching and transfer the workpiece to the mold closing area and the unloading area. After the equipment reaches the unloading station, the system cuts off the negative pressure air source, and the internal pressure of the horizontal plate 32 and the fixed cylinder 36 returns to normal. The return spring 39 is released elastically, pushing the piston plate 37 and the sliding rod 38 back to their initial positions. The positioning hole 40 on the sliding rod 38 is re-aligned with the valve stem 42 of the exhaust valve 41. When the electric telescopic cylinder 31 drives the horizontal plate 32 to reset upwards, the valve stem 42 of the exhaust valve 41 can smoothly extend into the positioning hole 40 without being squeezed and triggered. The exhaust valve 41 remains closed, and the air circuit of the second telescopic component remains sealed, improving the operational reliability of the entire pneumatic system and reducing the probability of equipment failure.

[0035] To facilitate the application of stamping lubricant to the mobile phone mid-plate to be processed, for example, such as... Figure 5 , Figure 8 , Figure 9As shown, the present invention also includes an oil storage cylinder 43 fixedly installed at one end of the first cylinder body 8, a push plate 44 sealed and slidably assembled inside the oil storage cylinder 43, a transmission push rod 45 fixed on one side of the push plate 44, and the end of the transmission push rod 45 penetrating into the first cylinder body 8; a compression spring 46 is installed between the push plate 44 and the inner wall of the oil storage cylinder 43, and the side of the push plate 44 away from the transmission push rod 45 and the inner wall of the oil storage cylinder 43 are filled with stamping lubricating fluid, and an atomizing nozzle 47 is assembled only on the lower surface of the horizontal plate 32 corresponding to the feeding area; a one-way liquid inlet valve and a one-way liquid outlet valve are connected to the oil storage cylinder 43, the one-way liquid inlet valve is connected to the liquid storage tank through a pipeline, and the one-way liquid outlet valve is connected to the atomizing nozzle 47 through a pipeline.

[0036] During use, after the stamping process is completed and the equipment performs the mold opening action, the pressure supply component delivers pressure medium to the side of the corresponding connecting joint 12 of the first cylinder 8, pushing the first sealing plate 9 to move inside the first cylinder 8. The first sealing plate 9 simultaneously drives the first drive rod 10 to extend outward. When the first sealing plate 9 moves to the specified stroke position, it will press against the transmission push rod 45. The transmission push rod 45 then pushes the push plate 44 inside the oil storage cylinder 43 to move. The push plate 44 compresses the internal space of the oil storage cylinder 43, squeezing the stamping lubricant stored inside. The pressurized lubricant is delivered to the atomizing nozzle 47 through the one-way outlet valve and the delivery pipeline. The atomizing nozzle 47 performs atomized spraying on the mobile phone middle plate to be processed in the loading area, specifically completing the pre-lubrication of the workpiece to meet the stamping process requirements. When the stamping device performs the mold closing action, the first sealing plate 9 in the first cylinder 8 retracts in the reverse direction and no longer squeezes the transmission push rod 45. At this time, the compression spring 46 in the oil reservoir 43 releases its elastic potential energy, pushing the push plate 44 and the transmission push rod 45 to reset, and a negative pressure is formed inside the oil reservoir 43. Under the action of negative pressure, the external stamping lubricating fluid is drawn into the oil reservoir 43 from the external storage tank through the one-way inlet valve to complete the replenishment, ensuring that the oil reservoir 43 has a continuous oil supply capacity, realizing the spraying and replenishment cycle, eliminating the need for frequent manual addition of lubricating fluid, and improving the automation level of the equipment.

[0037] To achieve simultaneous moving and air-jet cleaning operations, and to remove dust and impurities adhering to the mold surface and workpiece surface, for example, such as Figure 4 , Figure 11 , Figure 12 As shown, the present invention also includes a sealed air chamber 48 inside the movable plate 5, and a sealed sliding assembly jet plate 49 embedded in the upper and lower surfaces of the movable plate 5. Multiple sets of jet holes 50 are opened on the surface of the jet plate 49, and the jet holes 50 are all connected to the sealed air chamber 48. An installation plate 51 is fixed inside the sealed air chamber 48, and several sets of return springs 52 are connected between the installation plate 51 and the jet plate 49. Under normal conditions, the return springs 52 cause the jet plate 49 to fit against the surface of the movable plate 5. The sealed air chamber 48 is connected to the exhaust valve 41 through a pipeline.

[0038] During use, after the equipment completes the workpiece adsorption operation, the exhaust valve 41 is triggered to open, and the high-pressure compressed gas pre-stored inside the second telescopic component can be quickly discharged outward and the gas supply is completed. The discharged compressed gas is transported to the sealed air chamber 48 through the exhaust valve 17 and pipeline. The gas generates thrust, pushing the upper and lower jet plates 49 to slide outward respectively. The jet plates 49 simultaneously stretch the return spring 52 to store energy. After the jet plates 49 extend outward, the overall structure is closer to the upper mold stamping structure 23 and the lower bottom mold 19, effectively shortening the distance between the jet nozzle and the mold and workpiece, and improving the airflow impact effect and cleaning ability. At the same time, during the process of the moving plate 5 driving the workpiece to move horizontally from the loading area to the mold closing area and unloading area, dynamic cleaning operation is realized while moving and jetting. The airflow spray range covers the entire area and can remove dust and impurities attached to the mold surface and workpiece surface. The cleaning quality is far superior to the traditional fixed jet structure, and no manual cleaning is required. When the second telescopic component is fully reset, it stops supplying compressed gas to the sealed air chamber 48. The air pressure in the air chamber gradually decreases, and the stretched reset spring 52 releases its elastic tension, pulling the upper and lower sets of jet plates 49 inward to re-adhere to the surface of the moving plate 5. The jetting operation then stops. This mechanism starts and stops in conjunction with the workpiece transfer process, without the need for separate drive and control components. The cleaning process is completed without occupying additional production time, effectively improving the automation level and operational stability of the entire production line.

[0039] For example, such as Figure 4 As shown, the present invention also includes a positioning telescopic rod 53 fixedly installed between the connecting plate 7 and the support plate 30.

[0040] When in use, the positioning telescopic rod 53 can provide lateral limiting and auxiliary support for the support plate 30, effectively restraining the swaying and offset of the support plate 30, reducing the wear rate of parts, and extending the service life of the equipment.

[0041] When the present invention is in use, when the stamping device performs the mold closing action and stamps the middle plate of the mobile phone, the stamping plate 22 synchronously drives the second drive rod 25 of the pressure supply component to move downward, pushing the second sealing plate 54 to squeeze the lower cavity of the second cylinder 24. The pressurized gas is sent into the first cylinder 8 through the second connecting valve 27 and the first one-way air inlet valve 11. The air pressure pushes the first sealing plate 9 to drive the first drive rod 10 to retract, pulling the moving plate 5 and the two sets of telescopic suction cup devices backward together, so that the telescopic suction cup devices are completely removed from the working area of ​​the stamping device. This avoids a hard impact between the upper mold stamping structure 23 and the telescopic suction cup device during the mold closing process, improves the safety of equipment operation, and reduces component wear. During the mold closing process, the first sealing plate 9 retracts in the opposite direction and no longer squeezes the transmission push rod 45. The compression spring 46 in the oil storage cylinder 43 releases its elastic potential energy, pushing the push plate 44 and the transmission push rod 45 to reset. A negative pressure is formed inside the oil storage cylinder 43. Externally pressurized lubricating fluid is drawn into the oil storage cylinder 43 through the one-way inlet valve from the external storage tank to complete the replenishment. There is no need for frequent manual addition of lubricating fluid. Simultaneously, during the downward movement of the second sealing plate 54, a negative pressure environment is formed in the upper cavity of the second cylinder 24. External gas is drawn into the upper cavity of the second cylinder 24 through the upper air inlet valve 28 to complete the air replenishment, ensuring stable air pressure circulation inside the cylinder and reserving air source for subsequent mold opening operations. When the first drive rod 10 retracts to the designated limit position, the pressure relief valve 6 opens, and the pressurized gas continuously output by the pressure supply component continues to flow through the pressure relief valve 6 and is transported unidirectionally to the telescopic cylinder 13 of the second telescopic component via the second one-way air inlet valve 16. The air pressure inside the telescopic cylinder 13 continues to rise, pushing the piston rod to extend outward. Through the plate 15, the slide 4 slides along the track 3. The slide 4 simultaneously drives the moving plate 5 and the two sets of telescopic suction cup devices to move as a whole, so that the two sets of telescopic suction cup devices move to the area of ​​the electric feeding conveyor belt 1 and the mold closing area of ​​the stamping device, respectively, completing the pre-switching of the workstation. This does not occupy extra production time, effectively compresses the single process cycle, and improves the overall production efficiency. After the stamping process is completed, the stamping device performs the mold opening action. The electric hydraulic cylinder 21 drives the stamping plate 22 and the second drive rod 25 to reset upwards. The second sealing plate 54 moves upwards accordingly, squeezing the gas in the upper cavity of the second cylinder 24. The pressurized gas is transported to the connecting joint 12 of the first cylinder 8 through the first connecting valve 26 and pipeline. The pressure medium is introduced from the other end of the first cylinder 8, pushing the first sealing plate 9 and the first drive rod 10 outwards in the opposite direction, driving the moving plate 5 and the two sets of telescopic suction cup devices to move forward and reset synchronously. During the reverse movement of the first sealing plate 9, the corresponding space of the first cylinder 8 is squeezed again. The gas in the cylinder can be replenished to the second telescopic component through the pressure relief valve 6 to maintain the high pressure holding state of the second telescopic component. At the same time, when the first sealing plate 9 moves to the designated stroke position, the pressure transmission push rod 45 pushes the push plate 44 in the oil storage cylinder 43 to move, squeezing the stamping lubricating fluid and delivering it to the atomizing nozzle 47 through the one-way liquid outlet valve to perform atomized spraying on the mobile phone middle plate to be processed in the loading area. The pre-lubrication of the workpiece is completed at the same time as the mold opening and reset, which is compatible with the stamping process requirements. There is no need to set up a separate lubrication station, which further improves the integration and automation level of the production line. After the displacement is in place, the AI ​​vision detection module 35 on one side of the slide 4 identifies the station position in real time, determines the coordinates of the loading station and the stamping station, and sends a control command after confirming that the workpiece is in place. This drives the electric telescopic cylinders 31 of the two sets of telescopic suction cup devices to extend downwards in sync, causing the horizontal plate 32 to move down as a whole. The pipe joint 34 on the outside of the horizontal plate 32 is connected to an external negative pressure air source, and a negative pressure is formed in the cavity inside the horizontal plate 32. The two sets of suction cups 33 respectively adsorb the mobile phone middle plate to be processed on the electric loading conveyor belt 1 and the mobile phone middle plate that has been processed in the mold closing area of ​​the stamping device, and simultaneously complete the material picking operation. At the same time, the dual stations pick up materials simultaneously, which greatly shortens the material picking process time. After the workpiece is adsorbed, the electric telescopic cylinder 31 drives the horizontal plate 32 to return to its original position. The cavity inside the horizontal plate 32 maintains a negative pressure, and the fixed cylinder 36 connected to the cavity simultaneously forms a negative pressure. The piston plate 37 slides towards the horizontal plate 32, simultaneously stretching the return spring 39 to complete energy storage. The piston plate 37 drives the sliding rod 38 to move together, causing the positioning hole 40 on the sliding rod 38 to be misaligned with the valve stem 42 of the exhaust valve 41. When the horizontal plate 32 moves to the designated position, the sliding rod 38 and the valve stem 42 of the exhaust valve 41 are pressed against each other, triggering the exhaust valve 41 to open. After the exhaust valve 41 is opened, the high-pressure compressed gas stored in the telescopic cylinder 13 is quickly discharged outward. The piston rod automatically resets as the air pressure is released. The slide block 4 is pulled in the opposite direction by the plate 15, which simultaneously drives the moving plate 5 and the two sets of telescopic suction cup devices to move again, so as to move the workpiece to be processed from the loading area to the mold closing area and move the stamped workpiece to the unloading area. The discharged compressed gas is simultaneously transported through pipelines to the sealed air chamber 48 of the moving plate 5. The high-pressure gas pushes the upper and lower jet plates 49 to slide outwards, simultaneously stretching the return spring 52 to store energy. After the jet plates 49 extend outwards, they are close to the upper die stamping structure 23 and the lower die 19. The high-pressure airflow is ejected at high speed from the jet holes 50, realizing dynamic cleaning operation of moving and jetting during the entire process of horizontal workpiece transfer. After the jet plates 49 extend, the distance between the jet nozzle and the die and workpiece is shortened, and the airflow impact effect is stronger. It can remove dust and impurities attached to the surface of the die and workpiece, and the cleaning quality is far superior to the traditional fixed jet structure. Moreover, the cleaning process is completed simultaneously with the workpiece transfer, without occupying additional production time and without the need for manual cleaning. After the two sets of telescopic suction cup devices arrive at the unloading station, the AI ​​vision detection module 35 completes the station recognition again, drives the electric telescopic cylinder 31 to move the horizontal plate 32 downward, and at the same time the system cuts off the negative pressure air source, the negative pressure in the cavity of the horizontal plate 32 disappears, and the suction cup 33 releases its adsorption on the workpiece; the workpiece to be processed falls accurately into the stamping mold closing area, and the processed workpiece falls accurately into the electric unloading conveyor belt 2, completing the loading and unloading operations simultaneously; realizing the simultaneous picking and unloading of materials, greatly improving the production cycle and overall conveying efficiency; After the material feeding operation is completed, the electric telescopic cylinder 31 drives the horizontal plate 32 to return to its original position. After the negative pressure air source is disconnected, the horizontal plate 32 and the inside of the fixed cylinder 36 return to normal pressure. The return spring 39 is released elastically, pushing the piston plate 37 and the sliding rod 38 back to their initial positions. The positioning hole 40 on the sliding rod 38 is aligned again with the valve stem 42 of the exhaust valve 41. The exhaust valve 41 remains closed, and the air circuit of the second telescopic component returns to a sealed and pressure-maintaining state. At the same time, the air pressure in the sealed air chamber 48 gradually decreases, the stretched return spring 52 releases its elastic tension, and pulls the upper and lower sets of jet plates 49 to retract inward and re-attach to the surface of the moving plate 5, and the jetting operation stops immediately; each mechanism returns to its initial standby position in turn, and the entire set of equipment repeats the above process with the next round of mold closing action of the stamping device, realizing fully automated cyclic operation of mobile phone middle plate stamping and loading and unloading, without the need for separate configuration of multiple independent power and control units, simplifying the equipment structure and reducing the failure rate; greatly reducing manual intervention, reducing the intensity of manual labor, and improving the overall automation level of the production line.
