[0002] In the field of circuit board processing, traditional molding machines have many problems during the processing. First, in terms of positioning, the positioning accuracy of previous molding machines is insufficient, and it is difficult to ensure the precise placement of auxiliary boards and PCB boards during processing, resulting in low processing accuracy and uneven product quality. For example, due to positioning deviation, the lines on the circuit board may be slightly offset, affecting the performance of electronic products.

Detailed implementation manners

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0022] As Figures 1 to 3 shown, a molding machine 1 provided by the present application includes: A machine table 10, the machine table 10 includes a table board 11 and a top plate assembly 13, the table board 11 is provided with at least two guide post holes 111, at least two of the guide post holes 111 are arranged at intervals, the table board 11 is provided with at least two guiding holes 113, at least two of the guiding holes 113 are arranged at intervals, the top plate assembly 13 includes a lifting plate 131 and a driving member 133, the driving member 133 is drivingly connected to a side of the lifting plate 131 facing away from the table board 11, and at least two lifting members 1311 are provided on the lifting plate 131; Auxiliary plate 30, at least two guide posts 31 protrude from the auxiliary plate 30, at least two of the guide posts 31 are spaced apart, one of the guide posts 31 is correspondingly arranged with one of the guide post holes 111, the auxiliary plate 30 is provided with at least two receiving holes 33, at least two of the receiving holes 33 are spaced apart, one of the guiding holes 113 corresponds to one of the receiving holes 33, and one of the lifting members 1311 is docked with one of the guiding holes 113 and one of the receiving holes 33; Robot 50, a clamping assembly 51 is connected to the end of the robot 50, and the clamping assembly 51 is used for clamping and transporting the auxiliary plate 30.

[0023] Machine table 10, the machine table 10 includes a table top plate 11, at least two guide post holes 111 are formed in the table top plate 11, at least two of the guide post holes 111 are spaced apart, and one of the guide post holes 111 corresponds to one of the guide posts 31; the guide post holes 111 on the table top plate 11 of the machine table 10 are designed to cooperate with the guide posts 31 on the auxiliary plate 30, and their precise positions and sizes ensure that the auxiliary plate 30 can be stably installed on the machine table 10.

[0024] Optionally, at least two fixing components can be provided, at least two of the fixing components are both arranged on the machine table 10 and are spaced apart, and one of the fixing components corresponds to one of the guide post holes 111; the function of these fixing components is to fix the guide posts 31 on the auxiliary plate 30 in the guide post holes 111 of the machine table 10 to prevent them from shifting during operation, thereby ensuring the stability of the entire device and the accuracy of operation. The fixing components can be the cooperation of a clamping jaw and a cylinder, or the cooperation of a motor and a clamping jaw, or the cooperation of a cylinder and a pressing block. Two relatively arranged pressing blocks are used to press against each other to realize the holding and clamping of the guide post 31 and limit the position and displacement of the guide post 31.

[0025] When one of the guide posts 31 is correspondingly inserted through one of the guide post holes 111 and one of the fixing components correspondingly clamps one of the guide posts 31, a stable connection is formed, enabling the auxiliary plate 30 to be accurately positioned on the machine table 10 and providing a reliable reference for subsequent operations.

[0026] The auxiliary plate 30 is provided with at least two receiving holes 33 spaced apart, the table top plate 11 of the machine table 10 is correspondingly provided with at least two guiding holes 113 which are also spaced apart and correspond one by one, the lifting plate 131 of the top plate assembly 13 is provided with at least two lifting members 1311, and each of the lifting members 1311 can accurately correspond to the guiding holes 113 and the receiving holes 33. This one-to-one structural design enables the lifting force to be evenly distributed during the lifting process, effectively avoiding problems such as tilting and jamming of the auxiliary plate 30 due to uneven force, ensuring that the auxiliary plate 30 can move smoothly and vertically upward, and greatly improving the stability and accuracy of the lifting operation.

[0027] The provision of at least two lifting members 1311, receiving holes 33 and guiding holes 113 enables the device to be flexibly adjusted according to auxiliary plates 30 of different sizes, shapes and weights. By reasonably arranging the positions of the lifting points, various types of auxiliary plates 30 can be adapted, meeting diverse production and processing scenarios, enhancing the versatility and adaptability of the device, and reducing the cost for enterprises to frequently replace equipment due to changes in the specifications of the auxiliary plates 30.

[0028] When the driving member 133 drives the lifting plate 131, multiple lifting members 1311 act synchronously, simultaneously passing through the guiding holes 113 and docking with the receiving holes 33, and working together to drive the auxiliary plate 30 to move upward. Compared with the traditional design with a single lifting point or fewer lifting points, this multi-lifting-point method can quickly separate the auxiliary plate 30 from the machine table 10 in a short time, significantly improving the separation efficiency, reducing the time for the equipment to wait for the disassembly of the auxiliary plate 30, and increasing the overall production rhythm.

[0029] When actually installing this auxiliary device on the machine tool, first accurately fix the auxiliary plate 30 at a preset position above the machine tool table, ensuring that the receiving holes 33 of the lifting members 1311 are concentric with the reserved perforations on the machine tool table. The cylinders of the lifting members 1311 are installed on the corresponding brackets below the machine tool table, connected to the air source through air pipes, and the air path pressure is adjusted so that they can stably drive the lifting members 1311 to move up and down.

[0030] After placing the workpiece to be processed, the control system starts the driving member 133 according to the preset program or the information fed back by the sensors. The driving member 133 extends step by step according to the thickness requirement of the workpiece. During the upward movement of the lifting members 1311, they first pass through the guiding holes 113 and then abut against the receiving holes 33, ensuring uniform distribution of the supporting force. During the processing, the lifting members 1311 continuously provide stable support to prevent the workpiece from deforming. After the processing is completed, the cylinders of the lifting members 1311 retract, and the lifting members 1311 return to the initial position, waiting for the next processing operation.

[0031] The robot 50 is a key device for realizing automatic loading and unloading, and a clamping component 51 is connected to its end. The clamping component 51 is specially designed according to the shape and size of the auxiliary plate 30. Common types include pneumatic gripper type, electric gripper type, and vacuum adsorption type, etc. In this embodiment, the pneumatic gripper type clamping component 51 is adopted, and the gripper is driven to open and close by compressed air to achieve stable clamping and transportation of the auxiliary plate 30. The clamping component 51 has a high-precision positioning function, and can accurately place the auxiliary plate 30 and the PCB board on the table board 11 of the machine table 10 in sequence, and after the processing is completed, take out the auxiliary plate 30 and the PCB board to the processed temporary storage position.

[0032] The guide pin holes 111 on the panel 11 of the 10 machines 10 correspond to the guide pins 31 of the auxiliary plate 30 one by one. With the high-precision positioning of the robot 50 and the possible positioning assistance devices, the precise positioning of the auxiliary plate 30 on the machine 10 can be achieved, thereby accurately determining the processing position of the PCB board, reducing product quality problems caused by positioning deviation, and improving the yield rate of products. Through actual tests, using the positioning method of the present invention, the positioning accuracy of the product has been improved by more than 50% compared with the traditional method, and the yield rate has been increased to more than 98%.

[0033] By setting the robot 50 and the clamping component 51 at the end, the automatic grasping and transportation of the auxiliary plate 30 and the PCB board are realized. The robot 50 has a fast moving speed and high positioning accuracy. Compared with manual operation, the speed and efficiency of loading and unloading are greatly improved. It is estimated that using the robot 50 for loading and unloading, the single loading and unloading cycle is shortened from the original 30 seconds of manual operation to within 10 seconds, and the production efficiency is increased by more than 3 times. At the same time, the manual participation is reduced, the labor cost is lowered, and the production problems caused by manual operation errors are avoided.

[0034] The top plate assembly 13 of the machine 10 is provided with a lifting plate 131 and a driving member 133. The lifting member 1311 on the lifting plate 131 is docked with the guiding hole 113 of the table panel 11 and the receiving hole 33 of the auxiliary plate 30. After processing is completed, the driving member 133 drives the lifting plate 131 to rise, and the lifting member 1311 ejects the auxiliary plate 30 and the PCB board from the table panel 11, facilitating the robot 50 to take them out to the processed temporary storage position. This design simplifies the discharging process after processing is completed and shortens the single processing cycle. For example, in the actual application of a certain circuit board processing enterprise, using the discharging method of the present invention, the single processing cycle is shortened from the original 60 seconds to 40 seconds, and the overall production efficiency is increased by more than 33%, significantly improving the production capacity of the molding machine.

[0035] Furthermore, the molding machine further includes a movable ground rail mechanism 60. The movable ground rail mechanism 60 includes a rail 61 and a slider 63. The rail 61 is provided on one side of the machine 10, and the extending direction of the rail 61 is parallel to the extending direction of the machine 10. The slider 63 is slidably connected to the rail, and the robot 50 is installed on the slider 63.

[0036] Specifically, the movable ground rail mechanism 60 enables the robot 50 to move within a certain range, expanding the working area of the robot 50. The robot 50 can slide on the rail 61 to more flexibly grasp and place the auxiliary plate 30 and the PCB board, improving the operation convenience and production efficiency of the equipment.

[0037] Optionally, the rail 61 of the movable rail mechanism 60 can be selected as a heavy-duty linear guide rail, which features high rigidity, high precision, and low friction. It can bear the weight of the robot 50 and the load, ensuring the smooth movement of the robot 50. High-precision rolling bearings or sliding bushings can be installed between the slider 63 and the rail 61. Rolling bearings are suitable for high-speed motion scenarios, while sliding bushings have better seismic resistance and wear resistance, and can be selected according to the actual working environment. The robot 50 can be installed on the slider 63 by bolt connection or welding. Bolt connection is convenient for installation and disassembly, while welding can improve the firmness and stability of the connection.

[0038] Furthermore, the molding machine further includes a temporary storage mechanism 70. The temporary storage mechanism 70 is disposed on one side of the robot 50. The temporary storage mechanism 70 includes multiple layers of material placement racks, and the material placement racks are used to store the processed auxiliary plates 30 and PCB boards.

[0039] Specifically, the setting of the temporary storage mechanism 70 facilitates the temporary storage of the processed auxiliary plates 30 and PCB boards, avoiding the random placement of the processed materials, which is beneficial to the management of the production site and the material flow. The multiple layers of material placement racks can make full use of the space and improve the storage efficiency. It improves the material handling process of the molding machine and enhances the overall practicality of the equipment.

[0040] Optionally, the multiple layers of material placement racks of the temporary storage mechanism 70 can be designed as an adjustable structure, and the height of each layer can be adjusted by a screw-nut mechanism or a hydraulic lifting mechanism to adapt to auxiliary plates 30 and PCB boards of different thicknesses. The material of the placement rack can be selected as stainless steel or aluminum alloy. Stainless steel has good corrosion resistance, while aluminum alloy is light in weight and high in strength. The placement rack can also be equipped with a material identification system, such as a barcode scanner or an RFID reader / writer, to facilitate the rapid identification and management of materials.

[0041] The structural forms of the material placement racks can be divided into open shelves, drawer-type shelves, and rotary shelves. Open shelves are convenient for taking and placing materials. Drawer-type shelves can effectively protect the materials from the external environment. Rotary shelves can improve the space utilization rate and facilitate the rapid finding of the required materials. The barcode scanner of the material identification system can be selected as handheld or fixed. The RFID reader / writer can be divided into low-frequency, high-frequency, and ultra-high-frequency according to the working frequency, and the appropriate type can be selected according to the actual application scenario.

[0042] Further, the clamping assembly 51 includes a fixed clamping arm 511, a movable clamping arm 513, and a clamping member 515. The fixed clamping arm 511 is fixed to the end of the robot 50. The movable clamping arm 513 is connected to the fixed clamping arm 511 through an electric push rod. The electric push rod drives the movable clamping arm 513 to approach or move away from the fixed clamping arm 511. The clamping member 515 is movably connected to the movable clamping arm 513, and the clamping member 515 moves to clamp or release the auxiliary plate 30.

[0043] Specifically, in the design of the clamping assembly 51, by controlling the movement of the movable clamping arm 513 through the electric push rod, stable clamping and releasing operations of the auxiliary plate 30 can be achieved. The movable connection mode of the clamping member 515 can better adapt to the shape and size of the auxiliary plate 30, improving the reliability of clamping.

[0044] Optionally, the fixed clamping arm 511 and the movable clamping arm 513 of the clamping assembly 51 can be made of high-strength carbon fiber composite materials. This material has the characteristics of light weight, high strength, and good rigidity, which can improve the response speed and grasping accuracy of the clamping assembly 51. The electric push rod can be selected as a servo electric push rod with a position feedback sensor, which can accurately control the position and clamping force of the movable clamping arm 513. The clamping member 515 can be designed in various shapes and sizes, such as V-shaped chucks, flat chucks, or arc chucks, to adapt to auxiliary plates 30 of different shapes.

[0045] Optionally, in addition to the electric push rod, the driving mode of the clamping assembly 51 can also adopt pneumatic springs, hydraulic cylinders, or motor-driven link mechanisms. Pneumatic springs have a fast response speed, hydraulic cylinders have a large output force, and motor-driven link mechanisms have the advantages of simple structure and high reliability. The surface of the clamping member 515 can be treated with anti-slip measures, such as pasting rubber pads or knurling, to increase friction and improve the stability of clamping.

[0046] Further, the machine table 10 further includes a fixing assembly 115. The fixing assembly 115 is provided on the machine table 10. The fixing assembly 115 is arranged corresponding to the holes of the guide posts 31. The fixing assembly 115 includes a cylinder 151 and a clamping jaw 153. The cylinder 151 is drivingly connected to the clamping jaw 153 to drive the clamping jaw 153 to clamp or release.

[0047] Specifically, the fixing assembly 115 drives the clamping jaw 153 to clamp the guide post 31 through the cylinder 151, which can further fix the position of the auxiliary plate 30 on the machine table 10, prevent the auxiliary plate 30 from shifting during the processing, and improve the processing accuracy and stability.

[0048] Optionally, the cylinder 151 of the fixing component 115 of the machine tool 10 can be a compact cylinder 151 or a thin cylinder 151. The compact cylinder 151 occupies less space, while the thin cylinder 151 is suitable for occasions with higher requirements for installation space. The gripper 153 can be a parallel gripper, a three-point gripper or a swing gripper. The parallel gripper is suitable for gripping square or rectangular guide posts 31, the three-point gripper can provide a more stable gripping force, and the swing gripper is suitable for gripping guide posts 31 with irregular shapes. The fixing component 115 can also be equipped with a pressure sensor to monitor the gripping force of the gripper 153 in real time and ensure that the gripping force is within an appropriate range.

[0049] Further, the number of the guide posts 31 provided on the auxiliary plate 30 is four, and the four guide posts 31 are distributed at the four corners of the auxiliary plate 30 in a rectangular shape. The number of the guide post holes 111 opened on the table top plate 11 is four, and the four guide post holes 111 are distributed at the four corners of the table top plate 11 in a rectangular shape.

[0050] In the present invention, the auxiliary plate 30 is designed to be equipped with four guide posts 31. These guide posts 31 are evenly distributed at the four corners of the auxiliary plate 30, forming a rectangular layout. At the same time, four guide post holes 111 are correspondingly opened on the table top plate 11. These guide post holes 111 are also distributed at the four corners of the rectangle, corresponding to the positions of the guide posts 31 on the auxiliary plate 30 one by one. In addition, to ensure the stability and reliability of the structure, the number of the fixing components is also set to four. These fixing components are also distributed at the corresponding positions of the machine tool 10 at the four corners of the rectangle, matching the layout of the guide posts 31 and the guide post holes 111, thus ensuring the stability and precise alignment of the entire structure.

[0051] In practical applications, each fixing component includes a cylinder and a chuck. The cylinder realizes the telescopic movement of the chuck through pneumatic control. The chuck is designed to be able to closely fit the outer diameter of the guide post 31 to ensure that the auxiliary plate 30 does not displace in any way during the gripping state. In addition, to adapt to auxiliary plates 30 of different sizes, the gripping part of the chuck is designed to be adjustable, and can adapt to guide posts 31 of different diameters through simple mechanical adjustment. The control system adopts advanced sensor technology to monitor the gripping state and pressure data in real time to ensure the stability of the auxiliary plate 30 during the molding process. When the positioning of the auxiliary plate 30 is completed, the control system will automatically record the current gripping pressure value and continuously monitor it during the subsequent production process. Once an abnormal pressure value is detected, the system will immediately issue an alarm and stop the operation of the molding machine to prevent production defects caused by the displacement of the auxiliary plate 30.

[0052] The control system adopts advanced sensor technology to monitor the clamping state and pressure data in real time, ensuring the stability of the auxiliary plate 30 during the forming process. After the positioning of the auxiliary plate 30 is completed, the control system will automatically record the current clamping pressure value and continuously monitor it during the subsequent production process. Once an abnormal pressure value is detected, the system will immediately issue an alarm and stop the operation of the forming machine to prevent production defects caused by the displacement of the auxiliary plate 30.

[0053] Furthermore, the end of the guide post 31 is hemispherical.

[0054] Specifically, the end of the guide post 31 is hemispherical, which is convenient for preliminary guiding when inserting into the guide post hole 111, reducing collisions and scratches during the insertion process. In addition, the hemispherical end design of the guide post 31 also helps to provide a certain self-aligning function during the positioning of the auxiliary plate 30, enabling the auxiliary plate 30 to be more accurately aligned with the center line of the forming machine during the clamping process. This design not only improves the positioning accuracy of the auxiliary plate 30 but also reduces the risk of damage to the auxiliary plate 30 caused by inaccurate positioning. In actual operation, this self-aligning function greatly simplifies the installation process of the auxiliary plate 30 and improves production efficiency.

[0055] In order to further improve the performance of the positioning device of the auxiliary plate 30, the present embodiment also designs a positioning assistance system for the auxiliary plate 30. This system includes a set of precision guiding devices that work together with the guide post 31 and the chuck to ensure the accuracy of the auxiliary plate 30 during the insertion and positioning processes. The guiding devices are made of highly wear-resistant materials and can withstand long-term use without losing their accuracy. During the insertion of the auxiliary plate 30, the guiding devices can guide the auxiliary plate 30 to move along a predetermined path, thus avoiding damage to the auxiliary plate 30 or positioning deviation caused by improper operation. Specifically, the guiding devices can consist of guide rails fixed on the machine table and sliders installed on the auxiliary plate. The guide rails have high-precision straightness, and the sliders are precisely matched with the guide rails and can slide smoothly on the guide rails. When the auxiliary plate is inserted, the slider moves along the guide rail, restricting the auxiliary plate to move only in a predetermined straight direction, thereby ensuring that the auxiliary plate is accurately inserted into the corresponding position on the machine table, improving the positioning accuracy, and avoiding offsets caused by improper operation. In another embodiment, a guide sleeve is installed at the position corresponding to the guide post hole of the auxiliary plate on the machine table. The inner diameter of the guide sleeve has a precise fit tolerance with the outer diameter of the guide post. When the guide post of the auxiliary plate is inserted, the guide sleeve provides precise guidance for the guide post, enabling it to be accurately inserted into the guide post hole.

[0056] In addition, to accommodate auxiliary plates 30 of different thicknesses, the device is also designed with an adjustable clamping force control system. This system can automatically adjust the clamping force according to the thickness of the auxiliary plate 30 to ensure uniform and stable clamping on auxiliary plates 30 of different thicknesses. The adjustment of the clamping force is achieved through a precise hydraulic system, which can accurately control the pressure of the hydraulic cylinder to achieve fine adjustment of the clamping force.

[0057] Further, the lifting member 1311 includes a cylinder body and a buffer head located at the top of the cylinder body, and the shape of the buffer head is hemispherical.

[0058] Specifically, the hemispherical design of the buffer head helps to disperse the pressure during the lifting process, reduce the local stress on the workpiece, and thus protect the surface of the workpiece from damage. In addition, the buffer head is usually made of an elastic material to absorb the impact force during the lifting process, further ensuring the stability and machining accuracy of the workpiece. In practical applications, buffer head materials of different hardnesses can be selected according to the material and processing requirements of the workpiece to achieve the best lifting effect.

[0059] Further, the material of the buffer head is rubber or silica gel.

[0060] Specifically, the buffer head made of rubber or silica gel can provide good elasticity and durability, ensuring that the buffer head can effectively absorb the impact force during the lifting process while reducing the wear on the surface of the workpiece. When the rubber or silica gel buffer head contacts the workpiece, it can adapt to workpieces of different shapes and sizes, providing a uniform pressure distribution to avoid scratches or depressions on the surface of the workpiece. In addition, these materials also have good heat resistance and chemical stability, can maintain their performance in various working environments, and ensure the long-term stable operation of the lifting member 1311.

[0061] Further, an annular groove is provided on the outer side wall of the cylinder body, and the lifting member 1311 further includes a sealing ring, and the sealing ring is installed in the annular groove.

[0062] Specifically, the function of the sealing ring is to prevent leakage of liquid or gas during the lifting process, ensuring the cleanliness and safety of the working environment. The design of the annular groove enables the sealing ring to closely fit the outer side wall of the cylinder body, thus forming an effective sealing effect. In practical applications, the sealing ring is usually made of materials with good oil resistance, heat resistance, and aging resistance to adapt to different working conditions and extend the service life. In addition, the installation position and method of the sealing ring are also carefully designed to ensure that it will not shift or fall off during the lifting process, thus ensuring the stability and reliability of the entire lifting system.

[0063] After the lifting member 1311 is inserted into the receiving hole 33 of the lifting member 1311, the sealing ring is tightly pressed against the inner wall of the receiving hole 33 to form a reliable sealed connection. This can prevent impurities such as coolant and debris during the processing from entering the mating gap between the two, avoiding increased wear, and can also increase the frictional force between the lifting member 1311 and the receiving hole 33 to further stabilize the connection.

[0064] Further, the material of the column is alloy steel.

[0065] Specifically, the selection of alloy steel material is based on its excellent mechanical properties and corrosion resistance. Alloy steel has high strength and hardness, can withstand heavy loads and impact forces during the lifting process, and at the same time maintains the stability and durability of the structure. In addition, the corrosion resistance of alloy steel ensures the long-term use of the device in harsh environments, reducing maintenance costs and replacement frequencies. During the design, the heat treatment process of alloy steel is also considered to further improve its surface hardness and wear resistance, thereby extending the service life of the lifting member 1311 and ensuring the reliability of the ejection device during continuous operation.

[0066] Further, the inner wall of the receiving hole 33 is coated with a wear-resistant coating.

[0067] Specifically, the wear-resistant coating can effectively resist the wear generated by the frequent movement of the lifting member 1311, thereby extending the service life of the receiving hole 33. The selection of the coating takes into account its compatibility with alloy steel to ensure that the coating will not peel off or be damaged during the reciprocating movement of the lifting member 1311. In addition, the surface treatment of the wear-resistant coating can also reduce the friction coefficient, reduce the resistance during the movement of the lifting member 1311, and improve the working efficiency of the entire ejection device. In practical applications, this design significantly improves the performance of the ejection device and ensures the smoothness of the processing process and the quality of the product.

[0068] Preferably, the wear-resistant coating is a titanium nitride coating, which reduces the wear caused by the frequent entry and exit of the lifting member 1311, extends the service life of the auxiliary plate 30, and reduces the equipment maintenance cost.

[0069] Further, the auxiliary plate 30 is provided with an annular reinforcing rib at the edge of the receiving hole 33.

[0070] Specifically, the design of the annular reinforcing rib is aimed at enhancing the structural strength of the auxiliary plate 30 and preventing deformation caused by uneven stress during the ejection process. By arranging the annular reinforcing rib at the edge of the auxiliary plate 30, the stress generated during the movement of the ejecting member 1311 can be effectively dispersed, thereby improving the stability and reliability of the entire ejection device. In addition, the shape and size of the reinforcing rib are carefully designed to ensure the fitting accuracy with the receiving hole 33, avoiding unnecessary gaps during the ejection process and ensuring the accuracy and repeatability of the ejection action. In actual production, this structural design helps to reduce the failure rate of the equipment, improve production efficiency, and at the same time reduce the maintenance cost.

[0071] Preferably, the reinforcing rib is made of aluminum alloy and is integrally formed with the auxiliary plate 30 through a casting process. The annular reinforcing rib can significantly enhance the structural strength of the area around the receiving hole 33 of the ejecting member 1311, avoiding damage phenomena such as cracking and deformation of the auxiliary plate 30 at this part due to the frequent entry and exit of the ejecting member 1311 and the workpiece pressure.

[0073] Processing method of the molding machine: 1. Grasp the materials: The robot 50 drives the clamping assembly 51 to grasp the auxiliary plate 30 and the PCB board. During the grasping process, the robot 50 accurately locates the positions of the auxiliary plate 30 and the PCB board through the built-in vision recognition system to ensure that the clamping assembly 51 accurately grasps. The vision recognition system adopts a high-definition camera and an advanced image recognition algorithm, which can quickly identify the shape, position and posture information of the target object and transmit the data to the control system of the robot 50. The robot 50 adjusts its own posture and the position of the clamping assembly 51 according to these data to achieve accurate grasping.

[0074] 2. Loading and positioning: The robot 50 sequentially places the auxiliary plate 30 and the PCB board on the table board 11 of the machine table 10. The auxiliary plate 30 is placed in alignment with the guide post holes 111 of the table board 11 through the guide posts 31. During the placement process, the movement accuracy of the robot 50 is controlled within ±0.05 mm to ensure that the guide posts 31 of the auxiliary plate 30 can accurately insert into the guide post holes 111 to achieve accurate positioning. At the same time, a positioning auxiliary device, such as an optoelectronic sensor, can be set on the machine table 10. When the auxiliary plate 30 approaches the table board 11, the sensor detects the signal and feeds it back to the control system of the robot 50, and the robot 50 finely adjusts the position to further improve the positioning accuracy.

[0075] 3. Forming and processing: Start the operation of the forming machine. The machine table 10 processes the PCB board according to the preset processing parameters. During the processing, the processing environment is precisely controlled through a temperature control system, a pressure control system, etc. The temperature control system uses a cooling circulating water device to ensure that the temperature of the machine table 10 is stable within a certain range during the processing, avoiding affecting the processing accuracy and equipment life due to excessive temperature; the pressure control system adjusts the processing pressure in real time according to the processing technology requirements to ensure the processing quality.

[0076] 4. Ejecting materials: After the processing is completed, the jacking assembly drives the jacking plate 131 to rise, ejecting the auxiliary plate 30 and the PCB board from the table top plate 11. During the jacking process, the driving member 133 acts according to the preset speed and stroke, and the jacking member 1311 rises synchronously and inserts into the receiving hole 33 of the auxiliary plate 30 to evenly jack up the auxiliary plate 30 and the PCB board. The jacking speed is controlled at 5 - 10 mm per second to ensure a smooth ejection process and avoid shaking or damage to the auxiliary plate 30 and the PCB board due to too fast jacking speed.

[0077] 5. Unloading and temporary storage: The robot 50 takes out the auxiliary plate 30 and the PCB board to the processed temporary storage position. The robot 50 quickly and accurately transports the processed auxiliary plate 30 and PCB board to the processed temporary storage position according to the preset path planning. The temporary storage position is provided with a material placement rack, and the material placement rack adopts an adjustable design, which can adapt to the storage requirements of auxiliary plates 30 and PCB boards of different sizes, facilitating subsequent transfer and processing.
