Description

Technical Field

[0001] This invention relates to the field of silicone sealant filling technology, and in particular to an automatic silicone sealant filling and packaging equipment and process. Background Technology

[0002] Silicone sealant is an ointment-like material that hardens into a tough, rubber-like solid upon contact with moisture in the air. It is mainly classified into acetic acid-free, alcohol-free, ammonia-free, and propylene-free types. Because silicone sealant is commonly used for bonding and sealing glass, it is commonly known as glass sealant. While silicone sealant has low flowability, it solidifies very easily upon contact with air. Therefore, the efficiency of filling silicone sealant directly affects its quality. For already manufactured silicone sealant, the faster it is sealed and filled, the better its quality can be guaranteed.

[0003] The technical content disclosed in the Chinese patent document (Publication No.: CN217868076U, Patent Name: Quantifiable Silicone Glue Filling Device) is as follows: The purpose of this utility model is to provide a quantitative silicone glue filling device. The material enters the storage silo through the feeding device, and then the silicone glue is stirred by the rotation of the drive motor. Then, the silicone glue is filled through the flow valve, the conveying hose, the solenoid valve, and the filling pipe. The flow valve detects the filling volume, and when the specified value is reached, the solenoid valve closes. The device is controlled by the telescopic cylinder. The distance between the filling tube and the bottle mouth ensures that the filling process will not spill. The rotation of the first drive motor drives the main drive pulley, which in turn drives the driven pulley, which in turn drives the conveyor belt. The guide plate limits the filling bottle, thus realizing the conveying and precise filling of the filling bottle. The magnetic force generated by the electromagnet after being energized attracts the clamping gripper, thus clamping the bottle cap. The rotation of the second drive motor tightens the bottle cap, thus sealing the filling bottle. Finally, the filling machine achieves quantitative filling of silicone sealant.

[0004] As can be seen from the above implementation scheme, this scheme uses a belt to transport the filling bottles, and then automatically fills the bottles with silicone sealant and tightens the caps, thereby realizing automatic filling of silicone sealant. As can be seen from the view of this scheme, this scheme can only position and fill one filling bottle at a time, so the work efficiency is low. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies by incorporating a cylinder feeding component, a cylinder positioning component, and a cylinder picking component. This allows for the simultaneous and neat removal of multiple cylinders, followed by simultaneous filling and automatic capping. Compared to the traditional method of filling and capping a single cylinder, this significantly improves efficiency and silicone sealant packaging. It also reduces the waiting time between silicone sealant production and filling, ensuring timely encapsulation and guaranteeing the quality of the silicone sealant.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0007] An automatic silicone sealant filling and packaging equipment includes a cylinder feeding component, which can store and output individual cylinders. The lower end of the cylinder feeding component is connected to a cylinder positioning component, which can sequentially intercept individual cylinders. Below the cylinder positioning component is a cylinder picking component, which can simultaneously pick up several neatly arranged cylinders. A silicone sealant injection component is provided on one side of the cylinder picking component, and the silicone sealant injection component is connected to a silicone sealant mixing component.

[0008] An injection gripping component is provided above the cylinder assembly. The injection gripping component can simultaneously grip and place several cylinders filled with silicone sealant at the cylinder cover unloading component.

[0009] A finished product gripping component is provided on one side of the feeding component, which can simultaneously grip and place several finished products onto the conveying component.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The system is equipped with a cylinder feeding component, a cylinder positioning component, and a cylinder picking component, which can simultaneously and neatly pick up multiple cylinders. The silicone sealant mixing component mixes the silicone sealant to be packaged and then outputs it to the silicone sealant injection component. The silicone sealant injection component is equipped with multiple injection heads, which can simultaneously inject silicone sealant into the cylinder. The cylinder cap feeding component automatically seals the cylinder filled with silicone sealant. Compared with the traditional method of filling and capping a single cylinder, the efficiency is improved, the silicone sealant packaging efficiency is improved, and the waiting time from silicone sealant production to filling is further reduced, so that the silicone sealant can be sealed in a timely manner, ensuring the quality of the silicone sealant.

[0033] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0034] like Figures 1 to 19 As shown, an automatic silicone sealant filling and packaging device includes a cylinder feeding assembly 1, which can store and output individual cylinders 10. The lower end of the cylinder feeding assembly 1 is connected to a cylinder positioning assembly 2, which can sequentially intercept individual cylinders 10. Below the cylinder positioning assembly 2 is a cylinder picking assembly 3, which can simultaneously pick up several neatly arranged cylinders 10. A silicone sealant injection assembly 5 is located on one side of the cylinder picking assembly 3, connected to a silicone sealant mixing assembly 4. Above the cylinder picking assembly 3 is an injection gripping assembly 7, which can simultaneously dispense several cylinders 10 filled with silicone sealant. The finished product is gripped and placed at the cap feeding assembly 6. A finished product gripping assembly 8 is provided on one side of the feeding assembly 6. The finished product gripping assembly 8 can grip and place several finished products at the conveying assembly 9 at the same time. Compared with the traditional silicone sealant filling production line, the silicone sealant filling and packaging equipment of the present invention can position multiple cylinders 10 at the same time. Therefore, multiple cylinders 10 can be filled at the same time during filling, which greatly improves production efficiency. The improvement of filling efficiency also reduces the waiting time of silicone sealant from production to packaging. Shortening the waiting time of silicone sealant can effectively prevent silicone sealant from solidifying due to contact with air, and ensure the quality of silicone sealant in the filled cylinders 10.

[0035] The cylinder unloading assembly 1 includes an unloading frame 101, which includes a cylinder slide 1011. The cylinder slide 1011 is inclined, so when the cylinder 1 falls onto the cylinder slide 1011, it will automatically slide down from a high position without the need for other power drive mechanisms. A cylinder storage box 102 is provided at the upper end of the cylinder slide 1011, and a first outlet 1021 is provided at the lower end of the cylinder storage box 102. The first outlet 1021 allows only one cylinder 10 to pass through at a time. The front of the cylinder storage box 102 is a combination of a rectangle and an inverted triangle. The rectangular part can store more cylinders 10, and the inverted triangle part makes the cylinders 10 closer to the first outlet 1021 fewer. Therefore, it is ensured that the cylinders 10 will not jam when they are output from the first outlet 1021, thus ensuring the orderly output of the cylinders 10.

[0036] A discharge shaft 103 is provided at the lower end of the cylindrical storage box 102. The discharge shaft 103 has several discharge slots 1031, each capable of holding only one cylindrical body 10 at a time. One end of the discharge shaft 103 is connected to a discharge shaft drive motor 104. The discharge shaft drive motor 104 drives the discharge shaft 103 to rotate, sequentially aligning the empty discharge slots 1031 on the discharge shaft 103 with the area below the first outlet channel 1021. When an empty discharge slot 1031 is aligned with the area below the first outlet channel 1021, a cylindrical body 10 will fall from the first outlet channel 1021 into the empty discharge slot 1031. Once the empty discharge slot 1031 is filled, the cylindrical body 10 will no longer exit. The first discharge channel 1021 falls, and only when the discharge shaft 103 continues to rotate and the next empty discharge trough 1031 is rotated to be aligned with the first discharge channel 1021 will the second cylinder 10 fall into the empty discharge trough 1031. By repeating the above steps, one cylinder 10 can be taken out from the cylinder storage box 102 each time. The taken-out cylinder 10 rotates with the discharge shaft 103, which rotates in the direction of the cylinder slide 1011. When the discharge trough 1031 containing the cylinder 10 rotates to be above the cylinder slide 1011, the cylinder 10 will fall onto the cylinder slide 1011 and finally roll towards the cylinder drop hole 1012.

[0037] The lower end of the cylinder slide 1011 is provided with several cylinder drop holes 1012. Limiting holes 1013 are provided on the sides of the cylinder drop holes 1012, and limiting tracks 101A are provided on both sides of the limiting holes 1013. The cylinder positioning assembly 2 includes a limiting mechanism 201 and an insert plate mechanism 202. The limiting mechanism 201 is located above the cylinder drop holes 1012 and includes a limiting mounting base 20A. A limiting track is provided on the limiting mounting base 20A. A fence lifting cylinder 20B is included. The output end of the limiting fence 20B is connected to a limiting fence 20C. The limiting fence 20C is staggered with the cylinder's drop hole 1012. The insert plate mechanism 202 includes an insert plate cylinder 20D, which is connected to an insert plate 20E. The insert plate 20E is movably inserted into the limiting insertion hole 1013. Insert plate slide rails 20F are provided on both sides of the insert plate 20E, and the insert plate slide rails 20F are slidably inserted into the limiting rail 101A. Figure 8As shown, firstly, all the limiting barriers 20C rise, and all the insert plates 20E are inserted into the cylinder drop holes 1012. At this time, except for the cylinder drop hole 1012 furthest from the cylinder slide track 1011, the other cylinder drop holes 1012 are all blocked. When the first cylinder 10 rolls down from the cylinder slide track 1011, due to inertia, after passing over the blocked cylinder drop holes 1012, it will fall when it rolls onto the cylinder drop hole 1012 furthest from the cylinder slide track 1011. Then, the limiting barriers 20C furthest from the cylinder slide track 1011 will fall. As the cylinder descends, the second cylinder drop hole 1012, which is furthest from the cylinder slide 1011, is opened. When the second cylinder 10 rolls down from the cylinder slide 1011, due to inertia, after passing over several sealed cylinder drop holes 1012, the cylinder 10 hits the limiting fence 20C furthest from the cylinder slide 1011 and stops. Then the second cylinder 10 falls from the second cylinder drop hole 1012 furthest from the cylinder slide 1011. This process continues until cylinder 10s have fallen from all the provided cylinder drop holes 1012, thus completing one round of cylinder 10 retrieval.

[0038] The cylinder assembly 3 includes a sliding drive component 301. In this embodiment, the sliding drive component 301 is a cylinder. Sliding guide rails 302 are provided on both sides of the sliding drive component 301. The sliding drive component 301 is connected to the picking seat 303. The picking seat 303 is provided with several picking slots 3031. Each picking slot 3031 can only hold one cylinder 10 at a time. The sliding drive component 301 causes the picking seat 303 to move between the cylinder drop hole 1012 and the silicone injection assembly 5. The picking seat 303 first stops below the cylinder drop hole 1012, waiting for each cylinder 10 to fall from the cylinder drop hole 1012 into the picking slot 3031 in sequence. When the picking slots 3031 of the picking seat 303 are all filled, the picking seat 303 will move to the side of the silicone injection assembly 5 to wait for the cylinder 10 to be injected with silicone.

[0039] The silicone sealant mixing assembly 4 includes a mixing tank mounting base 401, on which a mixing tank 402 is mounted. The bottom of the mixing tank 402 has several silicone sealant outlets 4021. Mixing tank lid lifting components 403 are located on both sides of the mixing tank 402. In this embodiment, the mixing tank lid lifting component 403 is a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. The bottom end of the mixing tank lid lifting component 403 is connected to the mixing tank mounting base 401, and the output end of the mixing tank lid lifting component 403 is connected to the mixing tank lid 404. The mixing tank lid 404 has a sealant inlet 40. 41. A stirring motor 405 is installed on the mixing tank cover 404. The stirring motor 405 is connected to the stirring component 406. After the silicone sealant is produced, it is fed into the mixing tank 402 through the injection port 4041. Before the silicone sealant is output to the silicone sealant injection component 5, the stirring component 406 will continuously stir the silicone sealant to prevent it from solidifying. This stirring is only to make the silicone sealant move rather than to mix the silicone sealant ingredients evenly. Therefore, the impact force between the silicone sealant and the inner tank should not be too great during stirring, so that air bubbles are formed between the silicone sealant particles.

[0040] The stirring component 406 includes a stirring main shaft 4061, with support rings 4062 at both the upper and lower ends of the stirring main shaft 4061. The stirring main shaft 4061 and the support rings 4062 are connected by support connecting rods 4063. A spiral strip 4065 is arranged between the upper and lower support rings 4062, and a support vertical rod 4064 is arranged between the support connecting rods 4063 at both ends. The width of the spiral strip 4065 is less than 5 cm, and the diameter of the support vertical rod 4064 is between 3 and 5 cm. When the mixing component 406 rotates, the contact area between the spiral strip 4065 and the supporting vertical rod 4064 and the silicone sealant is small, and the force required to agitate the silicone sealant is small. Therefore, it can be controlled to ensure that the silicone sealant only flows and does not rotate rapidly and impact the barrel wall. The spiral strip 4065 is arranged in a spiral pattern from top to bottom. When agitated, the silicone sealant can be agitated along the spiral strip 4065 from top to bottom, so that the flow of the silicone sealant is comprehensive and uniform, ensuring that the silicone sealant in every position in the barrel is agitated and does not solidify.

[0041] The silicone sealant injection assembly 5 includes an injection base 501, an injection stage 503 slidably connected to the injection base 501, and an injection pusher 5024 slidably inserted into the injection stage 503. One end of the injection base 501 is connected to an injection stage drive motor 5012, which is connected to an injection stage drive screw 5013. First injection slide rails 5011 are also provided on both sides inside the injection base 501. The injection stage 503 is slidably connected to the first injection slide rails 5011. The injection stage 503 is threadedly connected to the injection stage drive screw 5013; the injection stage 503 includes a silicone sealant receiving stage 5032, a plurality of receiving stage inlets 503A are provided above the silicone sealant receiving stage 5032, a plurality of pushing chambers 503B are provided inside the silicone sealant receiving stage 5032, the plurality of pushing chambers 503B are not interconnected, an injection head 503C is provided at one end of the silicone sealant receiving stage 5032, and the pushing chambers 503B are connected to the injection head 503C.

[0042] The silicone sealant receiving platform 5032 is connected to the injection structure 502. The injection structure 502 includes an injection motor 5021, which is connected to an injection screw 5022. The injection screw 5022 is threadedly connected to the injection platform 5023. Second injection slide rails 5031 are provided on both sides of the silicone sealant receiving platform 5032, and the second injection slide rails 5031 are slidably connected to the injection platform 5023. An injection rod 5024 is connected to the injection platform 5023 near the silicone sealant receiving platform 5023. On one side of 032, the silicone sealant outlet 4021 is connected to the inlet 503A of the receiving platform via a flow control valve. The flow control valve can control the amount of silicone sealant input into the silicone sealant receiving platform 5032 from the silicone sealant stirring assembly 4, so that the silicone sealant receiving platform 5032 can maintain a certain amount of silicone sealant before each injection. Then, the push rod 5024 pushes the silicone sealant from the push chamber 503B to the injection head 503C, and finally injects it into the inside of the cylinder 10 from the injection head 503C.

[0043] In the process of injecting silicone sealant into the cylinder 10 by injection head 503C, firstly, under the drive of injection stage drive motor 5012, injection stage 503 inserts injection head 503C into the innermost part of cylinder 10. Then, as injection head 503C injects silicone sealant into cylinder 10, injection stage 503 gradually moves away from cylinder 10. In this way, injection head 503C injects silicone sealant into cylinder 10 while withdrawing, thus ensuring that the inside of cylinder 10 is completely filled with silicone sealant. This also prevents the injected silicone sealant from overflowing due to the pressure of cylinder 10 and injection head 503C. This injection method also prevents air from being mixed into the silicone sealant during the injection process. Because silicone sealant is a viscous colloid, it will not flow on its own unless disturbed. Therefore, silicone sealant can be injected using the horizontal injection method shown in the figure.

[0044] The injection gripping assembly 7 includes a gripping moving module 701, gripping moving slide rails 702 on both sides of the gripping moving module 701, a gripping moving base 703 connected to the gripping moving module 701, a first lifting cylinder 704 connected to the gripping moving base 703, an injection top block 705 connected to the output end of the first lifting cylinder 704, a second lifting cylinder 706 connected to the gripping moving base 703, a clamping cylinder 707 connected to the output end of the second lifting cylinder 706, and a clamping block 708 connected to the output end of the clamping cylinder 707. The injection top block 705 is provided with a cylindrical body middle section 7051 and a cylindrical body end section 7052. The clamping block 708 is provided with a clamping plate 7081. After the cylindrical body 10 is brought to the side of the silicone injection assembly 5 by the material take-up seat 303, the injection top block 705 descends and presses against the top of the cylindrical body 10. The cylindrical body end section 7052 matches the shape and size of the end of the cylindrical body 10 away from the silicone inlet. Therefore, when the injection head 503C injects silicone into the cylindrical body 10, the cylindrical body 10 is clamped vertically by the material take-up seat 303 and the injection top block 705. One end is held in place by the end fitting section 7052 of the cylinder body and will not be pushed. After the injection is completed, the injection head 503C is withdrawn, the clamping block 708 descends, and then the clamping block 708 moves towards the injection top block 705. The clamping plate 7081 also holds the end of the cylinder body 10 away from the injection top block 705. Then the clamping block 708 and the injection top block 705 clamp the cylinder body 10 and then bring the cylinder body 10 to the finished product pressure cap placement groove 6011 of the cylinder cover unloading base 601 and put it down. Then the clamping block 708 and the injection top block 705 release the cylinder body 10 and move away from the top of the cylinder body 10.

[0045] The cap feeding assembly 6 includes a cap feeding base 601, on which a plurality of finished cap placement slots 6011 are provided. Corresponding to the finished cap placement slots 6011, a cap storage box 602 is provided. The cap storage box 602 has the same cross-sectional area as the cylinder storage box 102. The difference is that, since the cap 11 is thinner, the inner cavity of the cap storage box 602 is narrower than the inner cavity of the cylinder storage box 102.

[0046] The lower end of the cap storage box 602 is provided with a second outlet 6021, which can only allow one cap 11 to pass through at a time. The lower end of the second outlet 6021 is connected to a cap ejection channel 6022, the shape of which matches the cap 11, and the cross-sectional space of which can only accommodate one cap 11. The cap ejection channel 6022 is coaxially arranged with the finished cap placement groove 6011. A pushing cylinder 603 is provided at the end of the cap ejection channel 6022 away from the finished cap placement groove 6011. The output end of the pushing cylinder 603 is connected to a pushing column 604, the cross-section of which is the same size and shape as the cap 11. The pushing column 604 is movably inserted into the cap ejection channel 6022. When the pushing column 604 is pulled back by the pushing cylinder 603, it pushes... The end face of the column 604 away from the push cylinder 603 is pulled to the side of the lower end of the second outlet 6021 near the push cylinder 603. At this time, a cap 11 falls off, and then the push column 604 pushes out, pushing the cap 11 towards the opening of the cylinder 10 filled with silicone sealant. The other end of the cylinder 10 is held in place by the finished product top block 802. Therefore, under the pressure of the push column 604 and the finished product top block 802, the cap 11 and the cylinder 10 are fitted together. Thus, the silicone sealant is sealed between the cylinder 10 and the cap 11. Since the cross-section of the push column 604 is the same size and shape as the cap 11, the push column 604 will block the lower end of the second outlet 6021 during the movement. In this case, the cap 11 will not fall from the second outlet 6021 to the cap ejection channel 6022.

[0047] The finished product gripping component 8 includes a finished product transfer component 801. In this embodiment, the finished product transfer component 801 is a cylinder, an electric cylinder, or a hydraulic cylinder. The finished product transfer component 801 is connected to the finished product top block 802. The bottom of the finished product top block 802 is provided with a finished product middle section 8022 and a finished product end section 8023. After the cylinder 10 is placed into the finished product cap placement groove 6011, the finished product top block 802 moves to the upper end of the cylinder 10 under the drive of the finished product transfer component 801. The finished product end section 8023 has the same shape as the end of the cylinder 10 away from the cylinder cap storage box 602.

[0048] A suction cup cylinder mounting base 8021 is provided on the upper part of the finished product top block 802. The suction cup cylinder mounting base 8021 is connected to the suction cup lifting cylinder 803. The output end of the suction cup lifting cylinder 803 is connected to the suction cup mounting plate 804. Several suction cups 805 are provided on the suction cup mounting plate 804. The suction cups 805 are movably inserted into the middle forming section 8022 of the finished product. After the cylinder 10 and the cylinder cover 11 are pressed together to form the finished product, the suction cups 805 are driven by the suction cup lifting cylinder 803 to descend and suck up the finished product. Therefore, when the finished product top block 802 moves above the conveying component 9, the finished product is also brought to the upper end of the conveying component 9. Then the suction cups 805 release the finished product, and the finished product falls to the conveying component 9 and is sent to the next process.

[0049] An automated process for filling silicone sealant, characterized by comprising the following steps:

[0050] A. Silicone sealant is fed into the mixing tank 402 through the injection port 4041. The stirring motor 405 drives the stirring component 406 to stir the silicone sealant to prevent it from solidifying.

[0051] B. The lower end of the mixing tank 402 is provided with several silicone sealant outlets 4021. The several silicone sealant outlets 4021 can simultaneously supply silicone sealant to several receiving inlets 503A of the injection stage 503. The silicone sealant outlets 4021 and the receiving inlets 503A are connected by a flow control valve.

[0052] C. The injection stage 503 is slidably connected to the injection base 501. When the injection stage 503 injects silicone sealant into the cylinder 10, the injection head 503C is first inserted deep into the cylinder 10. As the injected silicone sealant fills the inside of the cylinder 10, the injection head 503C gradually withdraws from the cylinder 10.

[0053] D. The cylinder feeding assembly 1 has an inclined cylinder sliding channel 1011. A cylinder storage box 102 is provided at the upper end of the cylinder sliding channel 1011. A discharge shaft 103 is provided below the cylinder storage box 102. A discharge groove 103 is distributed in a ring on the discharge shaft 103, which can only accommodate one cylinder 10 at a time. Only one cylinder 10 can pass through the first discharge channel 1021 of the cylinder storage box 102 at a time. As the discharge shaft 103 rotates, when it rotates to the point where the empty discharge groove 1031 is directly opposite the first discharge channel 1021, a cylinder 10 falls into the discharge groove 1031. Then the discharge shaft 103 rotates with the cylinder 10 towards the cylinder sliding channel 1011 until the cylinder 10 falls onto the cylinder sliding channel 1011.

[0054] E. The fallen cylinder 10 rolls along the cylinder slide 1011 toward the cylinder drop hole 1012;

[0055] F. The cylinder positioning assembly 2 is provided with a limiting mechanism 201 and an insert plate mechanism 202. The limiting mechanism 201 is provided with several limiting fences 20C. The limiting fences 20C and several cylinder drop holes 1012 are staggered. Before the first cylinder 10 falls, all the limiting fences 20C are in a raised state. Except for the cylinder drop hole 1012 that is farthest from the cylinder slide track 1011, all other cylinder drop holes 1012 are blocked by the insert plate 20E. At this time, the first cylinder 10 slides down from the cylinder slide track 1011. Due to inertia, the cylinder 10 will slide all the way to the cylinder drop hole 1012 that is farthest from the cylinder slide track 1011 and fall onto the material picker 303 of the cylinder picker assembly 3.

[0056] G. Before the second cylinder 10 falls, the limiting fence 20C furthest from the cylinder slide 1011 is lowered, and the insert plate 20E furthest from the cylinder slide 1011 is removed. At this time, the cylinder drop hole 1012 furthest from the cylinder slide 1011 is opened. Due to inertia, the second cylinder 10 will slide all the way to the cylinder drop hole 1012 furthest from the cylinder slide 1011. Because it is blocked by the limiting fence 20C furthest from the cylinder slide 1011, it will fall from the cylinder drop hole 1012 furthest from the cylinder slide 1011 and land on the picking seat 303 of the picking cylinder assembly 3.

[0057] H. Repeat step G until the material trough 3031 of the cylinder assembly 3 is completely filled.

[0058] 1. The cylinder assembly 3 pushes several cylinders 10 picked up from the material picker 303 to the front end of the injection head 503C of the silicone injection assembly 5. The grasping moving base 703 moves to directly above the material picker 303. The injection top block 705 descends and presses down on the cylinder 10. Since the cylinder end fitting section 7052 matches the end of the cylinder 10, the cylinder 10 will not be displaced when the injection head 503C injects silicone into the cylinder 10.

[0059] J. After the silicone sealant is injected, the injection head 503C exits the cylinder 10, the clamping block 708 descends and moves towards the injection top block 705. The clamping block 708 and the injection top block 705 simultaneously clamp several cylinders 10 and place them on the cylinder cover unloading base 601.

[0060] K. After the clamping block 708 and the injection top block 705 are removed, the finished product top block 802 moves to the cylinder cover unloading base 601. The finished product end fitting section 8023 of the finished product top block 802 holds one end of the cylinder body 10. The cylinder cover 11 falls from the cylinder cover storage box 602 to the cylinder cover ejection channel 6022. The pushing column 604 pushes the cylinder cover 11 out of the cylinder cover ejection channel 6022 until the cylinder cover 11 is pressed to one end of the opening of the cylinder body 10. At this point, the silicone sealant is sealed in the space formed by the cylinder body 10 and the cylinder cover 11.

[0061] L. Driven by the suction cup lifting cylinder 803, the suction cup 805 picks up the finished product on the cylinder cover unloading base 601. Then, driven by the finished product transfer component 801, the finished product top block 802 moves above the conveying component 9. The suction cup 805 releases the finished product, and the finished product falls onto the conveying component 9, which then sends the finished product to the next process.

[0062] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

8. A process for automatically filling silicone sealant using the automatic silicone sealant filling and packaging equipment described in claim 7, characterized in that, Includes the following steps, A. Silicone sealant is fed into the mixing tank (402) through the injection port (4041). The stirring motor (405) drives the stirring component (406) to stir the silicone sealant to prevent it from solidifying. B. The mixing tank (402) is provided with several silicone sealant outlets (4021) at the lower end. The several silicone sealant outlets (4021) can simultaneously supply silicone sealant to several container inlets (503A) of the injection stage (503). The silicone sealant outlets (4021) and the container inlets (503A) are connected by a flow control valve. C. The injection stage (503) is slidably connected to the injection base (501). When the injection stage (503) injects silicone sealant into the cylinder (10), the injection head (503C) is first inserted deep into the cylinder (10). As the injected silicone sealant fills the inside of the cylinder (10), the injection head (503C) gradually withdraws from the cylinder (10). D. The cylinder feeding assembly (1) has an inclined cylinder sliding channel (1011). A cylinder storage box (102) is provided at the upper end of the cylinder sliding channel (1011). A discharge shaft (103) is provided below the cylinder storage box (102). A discharge trough (1031) that can only accommodate one cylinder (10) at a time is distributed in a ring on the discharge shaft (103). Only one cylinder (10) can pass through the first discharge channel (1021) of the cylinder storage box (102) at a time. As the discharge shaft (103) rotates, when the empty discharge trough (1031) is facing the first discharge channel (1021), a cylinder (10) falls into the discharge trough (1031). Then the discharge shaft (103) rotates with the cylinder (10) towards the cylinder sliding channel (1011) until the cylinder (10) falls onto the cylinder sliding channel (1011). E. The fallen cylinder (10) rolls along the cylinder slide (1011) toward the cylinder drop hole (1012); F. The cylinder positioning assembly (2) is equipped with a limiting mechanism (201) and an insert plate mechanism (202). The limiting mechanism (201) is equipped with several limiting fences (20C). The limiting fences (20C) and several cylinder drop holes (1012) are staggered. Before the first cylinder (10) falls, all the limiting fences (20C) are in a raised state. Except for the cylinder drop hole (1012) that is furthest from the cylinder slide (1011), the other cylinder drop holes (1012) are blocked by the insert plate (20E). At this time, the first cylinder (10) slides down from the cylinder slide (1011). Due to inertia, the cylinder (10) will slide all the way to the cylinder drop hole (1012) that is furthest from the cylinder slide (1011) and fall down onto the picking seat (303) of the cylinder picking assembly (3). G. Before the second cylinder (10) falls, the limiting fence (20C) furthest from the cylinder slide (1011) is lowered, and the insert plate (20E) furthest from the cylinder slide (1011) is removed. At this time, the cylinder drop hole (1012) furthest from the cylinder slide (1011) is opened. Due to inertia, the second cylinder (10) will slide all the way to the cylinder drop hole (1012) furthest from the cylinder slide (1011). Because it is blocked by the limiting fence (20C) furthest from the cylinder slide (1011), it will fall from the cylinder drop hole (1012) furthest from the cylinder slide (1011) and land on the picking seat (303) of the picking cylinder assembly (3). H. Repeat step G in sequence until the material trough (3031) of the cylinder assembly (3) is filled; I. The cylinder assembly (3) pushes several cylinders (10) picked up from the pick-up seat (303) to the front end of the injection head (503C) of the silicone sealant injection assembly (5). The grasping moving base (703) moves to the top of the pick-up seat (303), and the injection top block (705) descends and presses on the top of the cylinder (10). Since the end fitting section (7052) of the cylinder matches the end of the cylinder (10), the cylinder (10) will not be displaced when the injection head (503C) injects silicone sealant into the cylinder (10). J. After the silicone sealant is injected, the injection head (503C) exits the cylinder (10), the clamping block (708) descends and moves towards the injection top block (705), the clamping block (708) and the injection top block (705) simultaneously clamp several cylinders (10) and place them on the cylinder cover unloading base (601). K. After the clamping block (708) and the injection top block (705) are removed, the finished top block (802) moves to the cylinder cover unloading base (601). The finished end fitting section (8023) of the finished top block (802) holds one end of the cylinder body (10). The cylinder cover (11) falls from the cylinder cover storage box (602) into the cylinder cover ejection channel (6022). The pushing column (604) pushes the cylinder cover (11) out of the cylinder cover ejection channel (6022) until the cylinder cover (11) is pressed against one end of the opening of the cylinder body (10). At this point, the silicone sealant is sealed in the space formed by the cylinder body (10) and the cylinder cover (11). L. The suction cup (805) is driven by the suction cup lifting cylinder (803) to pick up the finished product on the cylinder cover unloading base (601). Then, driven by the finished product transfer component (801), the finished product top block (802) moves above the conveying component (9). The suction cup (805) releases the finished product, and the finished product falls onto the conveying component (9). The conveying component (9) then sends the finished product to the next process.
