Description

Technical Field

[0001] This invention relates to the field of silicone molding machine technology, specifically to an automatic feeding and positioning system for multi-station silicone molding machines. Background Technology

[0002] A silicone molding machine is a device used to process silicone rubber raw materials, mainly solid high-temperature vulcanized silicone rubber and liquid silicone rubber, into products of specific shapes. Its core principle is to use heating and pressure to vulcanize and shape the silicone rubber in a mold.

[0003] When processing products with a silicone molding machine, operators need to pre-punch or cut the sheet or pre-cut rubber material to match the mold core before hot pressing. This process relies on manual labor or additional equipment, which not only significantly increases the cost and time of secondary processing, but also leads to production interruption and reduced overall efficiency. If the rubber material is placed directly for processing, it is difficult to guarantee the processing accuracy and yield. If the pre-punching step is omitted and the raw material is placed directly in the mold, the uncontrollable flow and displacement of the raw material during mold closing can easily cause the core to bend and be damaged under pressure, or cause defects such as uneven product wall thickness and hole offset, which seriously affect the dimensional accuracy and consistency of the product, and increase the mold maintenance cost and the scrap rate of finished products.

[0004] To address the aforementioned issues, we propose an automatic feeding and positioning system for a multi-station silicone molding machine. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic feeding and positioning system for a multi-station silicone molding machine, comprising an operating base, a rotary worktable on the top surface of the operating base, and N-type connecting frames fixedly installed on the left and right sides of the rotary worktable, respectively; an extrusion hot-melt assembly is installed in the left N-type connecting frame, and a conveying assembly is installed in the right N-type connecting frame; multiple positioning bottom molds are evenly arranged along the circumference of the top surface of the rotary worktable;

[0006] The extrusion hot melt assembly mainly consists of a driving component and an execution component, specifically including an electric telescopic rod and an extrusion hot die, with the extrusion hot die located directly below the electric telescopic rod. The conveying assembly includes a vacuum pump, a first moving mechanism, and a discharge vacuum suction cup. The vacuum pump is fixedly installed inside the N-type connecting frame on the right side and is connected to the discharge vacuum suction cup through a vacuum pipeline. Material conveying belts are provided on both adjacent sides of the operating base, and the height of the material conveying belts is on the same horizontal line as the height of the positioning bottom die.

[0007] The top surface of the operating base is fixedly installed with a support rod between two N-type connecting frames, and a second moving mechanism is installed on one side of the surface of the support rod. A material picking component is installed on the bottom surface of the second moving mechanism.

[0008] Furthermore, the positioning bottom mold includes a mounting base and an extrusion bottom mold, which are fixedly connected from top to bottom to form the core forming station of the device. The mounting base serves as a basic support component, and its bottom surface is fixedly mounted on the top surface of the rotary table by bolts to ensure that the positioning bottom mold can accurately index and rotate with the rotary table. Its top is machined with a flat mounting surface or positioning interface for accurately bearing and fixing the extrusion bottom mold above.

[0009] Furthermore, the electric telescopic rod serves as a power source, with its cylinder fixedly mounted on the N-type connecting frame on the left side. The extrusion hot die serves as a direct acting component, with its base fixedly connected to the output end of the electric telescopic rod, enabling the extrusion hot die to perform precise linear reciprocating motion under the drive of the electric telescopic rod.

[0010] Furthermore, the bottom surface of the first moving mechanism is fixedly installed on the upper side of the inner wall of the right-side N-type connecting frame, and its bottom is fixedly connected to the material feeding vacuum suction cup.

[0011] Furthermore, the material handling assembly includes a fixed base and two supporting vertical plates. The top of the fixed base is used to be fixedly connected to the output end of the second moving mechanism. The two supporting vertical plates are vertically fixedly installed on both sides of the bottom surface of the fixed base. The two supporting vertical plates are rotatably mounted with a power rod on opposite sides, and a material handling vacuum suction cup is fixedly installed on the rod wall of the power rod.

[0012] A shaped toothed block is fixedly installed at one end of the power rod near the support vertical rod. A reinforcing plate is fixedly installed on the side surface of the support vertical rod at the position corresponding to the movement trajectory of the shaped toothed block. Two stops are fixedly installed at the end of the reinforcing plate. On the surface of the reinforcing plate, in the area between the two stops, multiple meshing round rods are arranged in a straight line direction. The arrangement direction of these round rods is perpendicular to the rotation axis of the power rod.

[0013] The top of the irregular tooth block has an upward-convex arc-shaped profile, the left and right sides have slightly outward-convex vertical curve profiles, and the bottom has several evenly distributed rectangular tooth structures. The teeth of the irregular tooth block mesh with the surface of the meshing round rod.

[0014] Two electric heating soldering irons are slidably installed on the top surface of the fixed base near the stop block. Several tension springs are fixedly installed on the ends of the electric heating soldering irons and the surface of the fixed base. An extension block is fixedly installed on the side of the two stops away from the reinforcing plate. An L-shaped connecting block is fixedly installed on the top of the extension block. A locking block is fixedly installed on one end of the L-shaped connecting block. The locking block is engaged with the top surface of the electric heating soldering iron.

[0015] Furthermore, the material-collecting vacuum suction cup is installed between two supporting vertical plates and fixedly mounted on the wall of the power rod, and its posture can be adjusted within a certain angle as the power rod rotates.

[0016] Furthermore, the material-collecting vacuum suction cup is connected to the vacuum pump via a vacuum pipeline to obtain adsorption force.

[0017] Furthermore, both the first and second moving mechanisms adopt the same modular design in terms of structure, mainly consisting of an electric telescopic guide rail and a vertical electric telescopic rod.

[0018] Furthermore, in the conveying assembly, the output end of the vertical electric telescopic rod of the first moving mechanism is fixedly connected to the material discharge vacuum suction cup, while the output end of the vertical electric telescopic rod of the second moving mechanism is fixedly connected to the fixed base.

[0019] Furthermore, the material conveyor belt includes a movable base, a conveyor belt body, and two electric lifting telescopic rods. The movable base forms the overall foundation, the conveyor belt body is used to carry and transport silicone raw materials, and two electric lifting telescopic rods are installed between the movable base and the conveyor belt body to adjust the working height of the conveyor belt body to adapt to the docking requirements of different workstations.

[0020] Several connecting frames are fixedly installed on both sides of the conveyor belt, and an arc-shaped baffle is fastened to each connecting frame by bolts.

[0021] Compared with the prior art, the present invention provides an automatic feeding and positioning system for a multi-station silicone molding machine, which has the following advantages:

[0022] 1. The device integrates hot-melt softening and flipping feeding during the feeding process, which enhances the plasticity and fluidity of the silicone raw material, making it more easily deformable before entering the mold, laying the foundation for subsequent precise molding. The flipping feeding of the device ensures the pre-shaping and alignment of the softened raw material, allowing the pre-opening hole to be located in the mold core for better alignment, fundamentally eliminating the deviation caused by manual placement.

[0023] 2. This device can soften the raw material, ensuring that the raw material can uniformly and obediently wrap the core, greatly reducing the risk of core wear and bending caused by misalignment of hard raw materials during mold closing, ensuring the accuracy of product hole positions and the consistency of wall thickness, and improving mold life and product yield.

[0024] 3. The device automates and continuously completes the processing work, eliminating the need for separate pre-drilling, manual placement, and secondary adjustment processes, shortening the cycle, reducing labor and waste, and achieving dual optimization of efficiency and cost.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 4 The automatic feeding and positioning system of the multi-station silicone molding machine in this embodiment includes an operating base 1. A rotary worktable 2 is provided on the top surface of the operating base 1, and N-type connecting frames 3 are fixedly installed on the left and right sides of the rotary worktable 2 respectively. An extrusion hot melt assembly 4 is provided in the left N-type connecting frame 3, and a conveying assembly 5 is provided in the right N-type connecting frame 3. Multiple positioning bottom molds 6 are evenly arranged on the top surface of the rotary worktable 2 along its circumference.

[0039] The positioning bottom mold 6 includes a mounting base 601 and an extrusion bottom mold 602, which are fixedly connected from top to bottom, forming the core forming station of the device. The mounting base 601 serves as a basic support component, and its bottom surface is fixedly mounted on the top surface of the rotary table 2 by bolts, ensuring that the positioning bottom mold 6 can accurately index and rotate with the rotary table 2. Its top is machined with a flat mounting surface or positioning interface for accurately bearing and fixing the extrusion bottom mold 602 above.

[0040] The extrusion die 602 is a direct molding component. Its bottom surface is fixedly installed with the top mounting surface of the mounting base 601. The top surface of the extrusion die 602 is designed with a cavity or molding surface that matches the shape of the silicone product to be processed. It is used to receive the silicone raw material after the "hot melt softening" and "reverse extrusion" treatment in the previous station, and cooperates with the upper die in the final mold closing stage to complete the precise molding and shaping of the product.

[0041] The extrusion hot melt assembly 4 mainly consists of a driving component and an execution component, specifically including an electric telescopic rod 401 and an extrusion hot die 402, with the extrusion hot die 402 located directly below the electric telescopic rod 401. The conveying assembly 5 includes a vacuum pump 501, a first moving mechanism 502, and a discharge vacuum suction cup 503. The vacuum pump 501 is fixedly installed inside the N-type connecting frame 3 on the right side and is connected to the discharge vacuum suction cup 503 through a vacuum pipeline, providing a stable negative pressure source for the adsorption action. The first moving mechanism 502... The bottom surface is fixedly installed on the upper side of the inner wall of the right-side N-type connecting frame 3, and its bottom is fixedly connected to the discharge vacuum suction cup 503. The first moving mechanism 502 first drives the discharge vacuum suction cup 503 to move to the corresponding positioning bottom mold 6 position on the rotary worktable 2. Then the vacuum pump 501 starts, causing the discharge vacuum suction cup 503 to generate negative pressure, adsorbing the silicone raw material that has been heat-melted and softened. Finally, the first moving mechanism 502 moves again to transfer the raw material smoothly and accurately to the material conveyor belt 7, completing the automatic material picking.

[0042] Material conveyor belts 7 are provided on both adjacent sides of the operating base 1, and the height of the material conveyor belts 7 and the height of the positioning bottom mold 6 are on the same horizontal line. The electric telescopic rod 401 serves as the power source, and its cylinder fixed end is fixedly installed on the N-type connecting frame 3 on the left. The extrusion hot mold 402 serves as the direct action component, and its base is fixedly connected to the output end of the electric telescopic rod 401, so that the extrusion hot mold 402 can perform precise linear reciprocating motion under the drive of the electric telescopic rod 401. This component can drive the extrusion hot mold 402 to move downward through the control of the electric telescopic rod 401, and simultaneously perform a composite pretreatment action of hot melt softening and mechanical extrusion on the silicone raw material below.

[0043] Among them, the top surface of the operating base 1 is fixedly installed with a support rod 8 between two N-type connecting frames 3, and a second moving mechanism 9 is installed on one side of the surface of the support rod 8. The bottom surface of the second moving mechanism 9 is installed with a material picking assembly 10. The material picking assembly 10 includes a fixed seat 1001 and two support vertical plates 1002. The top of the fixed seat 1001 is used to be fixedly connected to the output end of the second moving mechanism 9. The two support vertical plates 1002 are vertically fixedly installed on both sides of the bottom surface of the fixed seat 1001. The two support vertical plates 1002 are rotatably installed with a power rod 1003 on opposite sides, and a material picking vacuum suction cup 1004 is fixedly installed on the rod wall of the power rod 1003. The first moving mechanism 502 and the second moving mechanism 9 adopt the same modular design in structure, mainly composed of an electric telescopic guide rail 901 and a vertical electric telescopic rod 902.

[0044] A shaped toothed block 1005 is fixedly installed at one end of the power rod 1003 near the support vertical rod 8. A reinforcing plate 1006 is fixedly installed on the side surface of the support vertical rod 8 at the position corresponding to the movement trajectory of the shaped toothed block 1005. Two stops 1007 are fixedly installed at the end of the reinforcing plate 1006. On the surface of the reinforcing plate 1006, in the area between the two stops 1007, multiple meshing round rods 1008 are arranged in a straight line. The arrangement direction of these round rods is perpendicular to the rotation axis of the power rod 1003.

[0045] The top of the irregular tooth block 1005 is an upward-convex arc-shaped profile, the left and right sides are slightly outward-convex vertical curve profiles, and the bottom is a number of evenly distributed rectangular convex tooth structures. The convex teeth of the irregular tooth block 1005 are meshed with the surface of the meshing round rod 1008.

[0046] Two electric heating soldering irons 1009 are slidably mounted on the top surface of the fixed base 1001 near the side of the stop block 1007. Several tension springs 1010 are fixedly mounted on the ends of the electric heating soldering irons 1009 and the surface of the fixed base 1001. An extension block 1011 is fixedly mounted on the side of the two stop blocks 1007 away from the reinforcing plate 1006. An L-shaped connecting block 1012 is fixedly mounted on the top of the extension block 1011. A locking block 1013 is fixedly mounted on one end of the L-shaped connecting block 1012. The locking block 1013 is engaged with the top surface of the electric heating soldering iron 1009.

[0047] The end of the electric heating soldering iron 1009 is engaged with the locking block 1013 via an inclined guide surface. The main body of the electric heating soldering iron 1009 consists of two heating columns and a block fixed to its end. This block structure matches and engages with the groove of the locking block 1013. When the second moving mechanism 9 drives the material picking assembly 10 to move downward, causing the material adsorbed on the material picking vacuum suction cup 1004 to contact the positioning bottom mold 6, the end of the electric heating soldering iron 1009 will first engage with the fixed locking block 1013. At this time, under the continuous downward movement of the second moving mechanism 9, the electric heating soldering iron 1009 will engage with the fixed locking block 1013. The hot soldering iron 1009 is constrained by the clamping block 1013 and moves upward. This action will be performed first. Then, the irregular toothed block 1005 engages with the meshing round rod 1008, thereby precisely locking the rotation of the power rod 1003 at a specific angle, namely 180 degrees. This series of continuous actions enables the material picking vacuum suction cup 1004 to complete precise flipping while the electric heating soldering iron 1009 heats and softens the material on it in a non-contact manner. Finally, the softened material is attached to the cavity of the positioning bottom mold 6 in a precisely aligned posture, which is ready for the subsequent extrusion hot pressing molding process.

[0048] The material-retrieving vacuum suction cup 1004 is installed between two supporting vertical plates 1002 and fixedly installed on the wall of the power rod 1003. It can adjust its posture within a certain angle as the power rod 1003 rotates. The material-retrieving vacuum suction cup 1004 is connected to the vacuum pump 501 through a vacuum pipeline to obtain adsorption force. The output end of the vertical electric telescopic rod 902 of the first moving mechanism 502 in the conveying assembly 5 is fixedly connected to the material-discharging vacuum suction cup 503, and the output end of the vertical electric telescopic rod 902 of the second moving mechanism 9 is fixedly connected to the fixed base 1001.

[0049] The material conveyor belt 7 includes a movable base 701, a conveyor belt body 703, and two electric lifting telescopic rods 702. The movable base 701 forms the overall foundation, the conveyor belt body 703 is used to carry and transport silicone raw materials, and the two electric lifting telescopic rods 702 are installed between the movable base 701 and the conveyor belt body 703 to adjust the working height of the conveyor belt body 703 to meet the docking requirements of different workstations.

[0050] Several connecting frames 704 are fixedly installed on both sides of the conveyor belt 703, and an arc-shaped baffle 705 is fastened to each connecting frame 704 by bolts. The opposing arc-shaped baffles 705 can form a progressive guiding channel above the conveyor belt 703, effectively preventing the sheet or block silicone raw material from shifting laterally, slipping, or piling up during the conveying process, and ensuring that the raw material is delivered to the picking station in a stable posture and along a predetermined path.

[0051] The working principle of the above embodiments is as follows:

[0052] When the material conveyor belt 7 starts, the arc baffles 705 on both sides ensure that the sheet or block silicone raw material is conveyed to the designated picking station in a stable posture. Then, the second moving mechanism 9 drives the picking component 10 at its end to move above the conveyor belt. The picking vacuum suction cup 1004 adsorbs the raw material under the negative pressure provided by the vacuum pump 501, and completes the automatic picking.

[0053] The second moving mechanism 9 drives the material picking component 10 to carry the raw material to an empty positioning bottom mold 6 on the rotary worktable 2. During the material picking process, the end of the electric heating soldering iron 1009 will perform a non-contact softening operation with the processing hole position carrying the raw material. When the material picking component 10 starts to move downward, the locking block 1013 on the L-shaped connecting block 1012 forms a locking with the electric heating soldering iron 1009, and the electric heating soldering iron 1009 is constrained and will remain in the same position. In this way, as the material picking component 10 continues to move downward, the electric heating soldering iron 1009 will move away from the raw material and will not affect the subsequent rotation operation.

[0054] The second moving mechanism 9 continues to drive the fixed base 1001 downward, while the clamped electric heating soldering iron 1009 slides upward relative to the fixed base 1001, stretching the tension spring 1010. In this relative movement, the heating column of the electric heating soldering iron 1009 moves away from the silicone raw material adsorbed on the material picking vacuum suction cup 1004. Under the previous softening, the silicone raw material can be softened quickly, enhancing its plasticity.

[0055] As the fixed base 1001 continues to descend, the irregular toothed block 1005 fixed to the end of the power rod 1003 enters the area between the two stops 1007 on the reinforcing plate 1006 and engages with the array of meshing round rods 1008. This meshing action converts the linear downward movement of the power rod 1003 into a precise rotational motion, driving the power rod 1003 to rotate 180 degrees.

[0056] The rotation of the power rod 1003 drives the material-picking vacuum suction cup 1004 on it and the softened silicone material adsorbed thereon to rotate synchronously. After the vacuum is released, the material is flatly attached to the cavity of the positioning bottom mold 6 under precise alignment. In particular, the holes on the material can automatically align with the mold core, completing the precise positioning without pre-drilling.

[0057] After the silicone raw material is attached to the positioning mold 6, the rotary table 2 rotates according to the set rhythm, transferring the workstation carrying the raw material to the extrusion hot melt assembly 4 on the left. The electric telescopic rod 401 drives the extrusion hot mold 402 to descend, and finally heats and pressurizes the silicone raw material that has been initially softened and positioned to pre-form it, so that it can be further shaped and completely fill the cavity, making full preparation for the final molding.

[0058] After pre-compression, the rotary table 2 rotates again, transferring the workstation with the semi-finished product to the right-side conveying component 5. The first moving mechanism 502 drives the unloading vacuum suction cup 503 to descend, pick up the semi-finished product, and then transfer it to the discharge assembly line or the next processing station. At the same time, the empty positioning bottom mold 6 rotates back to the picking station with the rotary table 2, and the system starts the next work cycle. This application highlights the innovative structure and does not elaborate on existing mature technologies. For example, the vacuum suction cup of this application has the effect of intelligent switch control, which will not be elaborated on in this application, as well as the rotary table 2, the electric telescopic guide rail 901, and other structures.

[0059] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
