Description

Technical Field

[0001] This invention relates to the field of skylight foaming technology, and more specifically, to an auxiliary device for skylight foaming injection and its working method. Background Technology

[0002] Automotive sunroof foaming is a technology that uses materials such as polyurethane, mixed with catalysts, foaming agents and other additives, and then foamed and expanded under certain temperature and pressure to produce sunroof-related components. After the components are made, they are used to manufacture sunroof sun visors, seals and surrounding buffer components, achieving advantages such as lightweighting, heat insulation, sound insulation and noise reduction, sealing and vibration reduction, and improving the driving comfort and performance of automobiles.

[0003] Currently, in order to meet the needs of dynamic transmission in the production process, foam boxes are set on conveyor trolleys. The conveyor trolleys can be connected to the automated control system of the production line to realize intelligent scheduling of the foam box transportation process, match the rhythm of the assembly line operation, improve the overall production efficiency, and maintain the stability of the foam boxes during transportation to prevent changes in the state of the foam material or damage to the products due to bumps, thus ensuring the continuity of the production process and product quality.

[0004] However, existing transfer trolleys are usually pushed directly to the processing position and then directly injected for foaming. However, in this case, the foaming liquid is directly injected into the foaming box, resulting in uneven coverage of the foaming liquid in the foaming box. Due to the uneven distribution of the foaming liquid, the foaming effect will be affected, and ultimately the use of subsequent materials will be affected. Now, an auxiliary device for skylight foaming injection and its working method are proposed to improve the existing problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an auxiliary device for skylight foaming injection and its working method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for foaming and injecting material for a sunroof, comprising a transfer component, an injection component disposed on one side of the transfer component, a limiting component disposed in the middle of the transfer component, a foaming component disposed above the limiting component, and an auxiliary component disposed above the foaming component.

[0007] The injection assembly includes an injection mechanism and a transfer electric slide rail disposed at the bottom of the injection mechanism.

[0008] The foaming assembly includes a foaming box, and two sets of telescopic cylinders are symmetrically arranged below the foaming box.

[0009] The limiting component includes a mounting platform, and two sets of guide rails are symmetrically arranged on the top of the mounting platform.

[0010] The auxiliary component includes a connecting plate, a pressure plate is provided below the connecting plate, and two sets of limiting structures are symmetrically provided on the top of the pressure plate. A set of locking mechanisms is provided above each of the two sets of limiting structures, and the limiting structures are adapted to the locking mechanisms.

[0011] By adopting the above technical solution, when the foaming component is pushed to the position of the limiting component, the four sets of guide wheels of the foaming component move along the two sets of guide rails. The guide rails limit the movement trajectory of the guide wheels, ensuring that the foaming component maintains a straight line during the pushing process, reducing the possibility of collision or misalignment with surrounding equipment due to deviation. At the same time, since the foaming component moves in a straight line, it is easier to determine the position of the foaming component, which is beneficial to the cooperation between the auxiliary component and the foaming component. In addition, a chamfer is provided at the end of the mounting platform, and a chamfer is provided at the position that contacts the guide wheels. By setting the chamfer, the right-angle collision and jamming between the guide wheels and the mounting platform can be reduced.

[0012] The present invention is further configured such that: the transfer assembly includes a support frame, a first electric slide rail is provided on the top of the support frame, a bracket is provided on the top of the first electric slide rail, a second electric slide rail is provided on one side of the bracket, a third electric slide rail is provided on the side of the second electric slide rail away from the bracket, a connecting frame is provided on the side of the third electric slide rail away from the second electric slide rail, and the auxiliary assembly is provided at the bottom of the connecting frame.

[0013] The present invention is further configured such that: the foaming component also includes a mounting frame, and a set of guide wheels are respectively provided at the four bottom corners of the mounting frame, and two sets of telescopic cylinders are symmetrically arranged at the top of the mounting frame.

[0014] The present invention is further configured such that: two sets of connecting columns are symmetrically arranged on the top of the mounting frame, a mounting base is arranged above the two sets of connecting columns, and a set of connecting members is arranged on both sides of the mounting base; the two sets of connecting members are arranged opposite to the two sets of connecting columns, and the two sets of connecting columns are respectively hinged to the two sets of connecting members.

[0015] The invention is further configured such that: the foaming box is disposed on the top of the mounting base, and two sets of connecting members are symmetrically disposed on the bottom of the mounting base; the two sets of connecting members are respectively hinged to the two sets of telescopic cylinders; and the ends of the two sets of telescopic cylinders away from the two sets of connecting members are respectively hinged to the mounting frame.

[0016] The present invention is further configured such that: two sets of adjusting cylinders are symmetrically arranged on the top of the connecting plate, the two sets of adjusting cylinders are arranged diagonally, and two sets of connecting seats are symmetrically arranged below the connecting plate, the output ends of the two sets of adjusting cylinders pass through the connecting plate and are respectively connected to the two sets of connecting seats.

[0017] The present invention is further configured such that: a telescopic rod is provided at the middle position of the two sets of connecting seats, a first hinge post is provided at one end of the telescopic rod, one end of the first hinge post is hinged to the telescopic rod, the other end of the first hinge post is fixedly connected to the connecting plate, a second hinge post is provided at the other end of the telescopic rod, one end of the second hinge post is hinged to the telescopic rod, and the other end of the second hinge post is fixedly connected to the pressure plate.

[0018] The present invention is further configured such that: the clamping mechanism includes a clamping cylinder, and the output end of the clamping cylinder is respectively provided with two sets of clamping claws, and the shape of the clamping claws is configured as an L-shaped structure.

[0019] The present invention is further configured such that: the limiting structure includes a buckle, a buckle groove is provided at the bottom center of the buckle, two sets of uprights are symmetrically arranged at the bottom of the buckle, one end of the uprights is connected to the buckle, and the other end of the uprights is connected to the pressure plate.

[0020] By adopting the above technical solution, the opening and closing of the gripper is controlled by a pneumatic clamping cylinder, and the up and down movement of the adjusting cylinder is coordinated to achieve engagement or disengagement with the limiting structure. When the clamping cylinder opens the gripper, and the adjusting cylinder drives the engagement mechanism to move upward, the gripper engages with the slot of the limiting structure, making the pressure plate and the connecting plate rigidly connected. When the adjusting cylinder drives the engagement mechanism to move downward, the gripper moves away from the slot and tightens, and the engagement mechanism disengages from the limiting structure, forming a gap. The engagement is locked by the cooperation of the slot and the gripper. At the same time, after the engagement mechanism moves downward and disengages, the gap between the two provides space for the pressure plate to swing. The buckle serves as a positioning reference to ensure that the gripper maintains a safe distance from the limiting structure when it is tightened, reducing interference. This allows the pressure plate to swing freely within the gap range, meeting the dynamic adjustment requirements.

[0021] A method for operating an auxiliary device for skylight foaming injection, using the auxiliary device for skylight foaming injection as described above, includes the following steps: S1. First, place the foaming component in the position of the limiting component and adjust the foaming component to be in an inclined state.

[0022] S2. Next, after the position of the foaming component is determined, foaming liquid is injected into the interior of the foaming component through the injection component. Following the injection of the injection component, the foaming component is gradually adjusted to a tilted state. When the foaming liquid injection is completed, the foaming component is adjusted to a flat state.

[0023] S3. Then, once the foaming component is in a flat state, immediately adjust the position of the auxiliary component using the transfer component so that the auxiliary component is opposite to the foaming component and covers the top of the foaming component with the auxiliary component.

[0024] S4. After the auxiliary component is placed on top of the foaming component, immediately shake the foaming component and the auxiliary component quickly and gently again. After shaking is complete, the foaming liquid begins to foam. After foaming is complete, start the transfer component to detach the auxiliary component from the foaming component.

[0025] In summary, this application includes at least one of the following beneficial technical effects: (1) By utilizing the hinged relationship between two sets of telescopic cylinders and the mounting base, connectors, and connecting columns, the tilt angle of the mounting base is changed by the extension and retraction of the cylinders, thereby causing the foaming box to tilt. During the injection, the tilted foaming box allows the foaming liquid to flow and diffuse naturally along the inclined surface under the action of gravity. As the injection proceeds, the telescopic cylinders gradually extend, and the foaming box is restored to a horizontal position when the injection is completed. This design effectively promotes the uniform distribution of foaming liquid, reduces local accumulation, and improves the foaming quality through the tilted injection method. At the same time, the box is reset to a horizontal position after injection, providing a stable foundation for subsequent foaming and molding, reducing manual intervention, and improving production efficiency and process stability.

[0026] (2) After the pressure plate is closed, the foaming box and the pressure plate as a whole are shaken quickly and gently. The immediate shaking can cause large bubbles to break into small bubbles or cause bubbles to escape from the liquid surface, reducing the risk of voids and cracks in the foam.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0039] Please see Figure 1-9 The present invention provides the following technical solutions: In the existing process of foaming automotive sunroofs, the foaming liquid is directly injected into the housing for foaming. However, the foaming liquid may not cover the housing evenly, which affects the foaming effect.

[0040] See Figure 1 To solve the above problems, an auxiliary device for skylight foaming injection is set up to reduce the uneven distribution of foaming liquid. The auxiliary device for skylight foaming injection includes a transfer component 1, an injection component 2 is set on one side of the transfer component 1, a limiting component 4 is set in the middle of the transfer component 1, a foaming component 3 is set above the limiting component 4, and an auxiliary component 5 is set above the foaming component 3.

[0041] The transfer component 1 is mainly used to assist in adjusting the position of the auxiliary component 5 so that the auxiliary component 5 can cooperate with the foaming component 3 to achieve subsequent foaming.

[0042] By setting auxiliary component 5, the foaming pressure inside foaming component 3 is controlled. Auxiliary component 5 and foaming component 3 form a closed environment. In the closed environment, when the foaming material expands, it will form a stable pressure in the mold. This pressure will cause the material to fill the mold. If auxiliary component 5 is not set, the pressure will leak out, resulting in the material not being able to fully fill the mold, and the finished product will have defects such as missing material and uneven surface.

[0043] The specific structure of the transfer component 1 is as follows: See Figure 2 and Figure 3 The transfer assembly 1 includes a support frame 11, a first electric slide rail 12 is provided on the top of the support frame 11, a bracket 13 is provided on the top of the first electric slide rail 12, a second electric slide rail 14 is provided on one side of the bracket 13, a third electric slide rail 15 is provided on the side of the second electric slide rail 14 away from the bracket 13, a connecting frame is provided on the side of the third electric slide rail 15 away from the second electric slide rail 14, and an auxiliary assembly 5 is provided at the bottom of the connecting frame.

[0044] By setting a connecting frame, the auxiliary component 5 can be connected to the transfer component 1, which makes it easier for the transfer component 1 to control the movement of the auxiliary component 5.

[0045] The motion flow of transfer component 1 is as follows: First, the first electric slide rail 12 is activated, which drives the bracket 13, the second electric slide rail 14, the third electric slide rail 15, and the auxiliary component 5 to move horizontally in the front and back directions. Next, the second electric slide rail 14 is activated, which drives the third electric slide rail 15 and the auxiliary component 5 to move horizontally in the left and right directions. Finally, the third electric slide rail 15 is activated, which drives the auxiliary component 5 to move vertically in the up and down directions.

[0046] Driven by the first electric slide rail 12, the second electric slide rail 14, and the third electric slide rail 15, the auxiliary component 5 can be adjusted in the front, back, left, right, up, and down positions, which facilitates the subsequent cooperation between the auxiliary component 5 and the foaming component 3.

[0047] Injection assembly 2 is used to inject foaming liquid into foaming assembly 3. The specific structure of injection assembly 2 is as follows: See Figure 2 and Figure 3 The injection assembly 2 includes an injection mechanism 21 and a transfer electric slide rail 22 disposed at the bottom of the injection mechanism 21.

[0048] The injection mechanism 21 includes a robotic arm and an injection head. The robotic arm is used to adjust the position of the injection head to facilitate the injection of foaming liquid. The injection head is connected to an external liquid supply device, which provides foaming liquid to the injection mechanism 21, specifically through a delivery pump.

[0049] The electric transfer slide rail 22 is used to adjust the overall position of the injection mechanism 21. In actual operation, when the electric transfer slide rail 22 is started, the electric transfer slide rail 22 can drive the injection mechanism 21 to move back and forth, reducing the possibility of collision between the injection mechanism 21 and the auxiliary component 5.

[0050] Foaming component 3 is used to provide the corresponding reaction environment for foaming. The specific structure of foaming component 3 is as follows: See Figure 4 and Figure 5 The foaming component 3 includes a foaming box 38, and two sets of telescopic cylinders 33 are symmetrically arranged below the foaming box 38.

[0051] The foaming chamber 38 provides a suitable reaction environment for foaming, facilitating the normal operation of the foaming process.

[0052] See Figure 4 and Figure 5 The foaming component 3 also includes a mounting bracket 31, with a set of guide wheels 32 at each of the four bottom corners of the mounting bracket 31, and two sets of telescopic cylinders 33 symmetrically arranged on the top of the mounting bracket 31.

[0053] By setting four sets of guide wheels 32, the foaming component 3 can be moved as a whole. In practical applications, it can meet the needs of dynamic transmission in the production process. It can be connected to the automated control system of the production line to realize intelligent scheduling of the transportation process of the foaming component 3, match the rhythm of the assembly line operation, improve the overall production efficiency, and maintain the stability of the foaming component 3 during transportation to prevent changes in the state of the foaming material or damage to the product due to bumps, thus ensuring the continuity of the production process and product quality.

[0054] See Figure 9 The guide wheel 32 is a self-locking caster. Its structure is usually based on an ordinary caster with the addition of a braking device. It can quickly switch between walking and locking states through foot operation. This type of caster generally consists of a wheel, a mounting bracket and a self-locking mechanism. When it is necessary to fix the equipment, stepping on the brake pedal will lock the wheel rotation through the brake pads to prevent the equipment from sliding or shifting.

[0055] See Figure 4 and Figure 5 The top of the mounting bracket 31 is symmetrically provided with two sets of connecting columns 35. Above the two sets of connecting columns 35, there is a mounting base 37. On both sides of the mounting base 37, there is a set of connecting parts 36. The two sets of connecting parts 36 are arranged opposite to the two sets of connecting columns 35, and the two sets of connecting columns 35 and the two sets of connecting parts 36 are respectively hinged.

[0056] See Figure 4 and Figure 5The foaming box 38 is located on the top of the mounting base 37. Two sets of connectors 34 are symmetrically arranged at the bottom of the mounting base 37. The two sets of connectors 34 are respectively hinged to two sets of telescopic cylinders 33. The ends of the two sets of telescopic cylinders 33 away from the two sets of connectors 34 are respectively hinged to the mounting frame 31.

[0057] The foaming box 38 is connected to the mounting base 37 by bolts, which facilitates the disassembly of the foaming box 38 and the subsequent cleaning or replacement of the foaming box 38.

[0058] The working process of foaming component 3 is as follows: First, the two sets of telescopic cylinders 33 are activated. Since the two sets of telescopic cylinders 33 are hinged to the mounting base 37 and the two sets of connecting parts 36 are hinged to the two sets of connecting columns 35, the mounting base 37 is tilted under the action of the two sets of telescopic cylinders 33. At the same time, the foaming box 38 connected to the mounting base 37 is also tilted. At this time, the two sets of telescopic cylinders 33 are in a retracted state. Second, the transfer electric slide rail 22 is activated. The transfer electric slide rail 22 drives the injection mechanism 21 to move horizontally to the position of the foaming box 38. The manipulator of the injection mechanism 21 controls the injection head to penetrate into the foaming box 38. The injection head begins to inject foaming liquid. Since the foaming box 38 is tilted, the foaming liquid can flow from one side of the foaming box 38 along the slope to the other side, realizing the flow and diffusion of the foaming liquid. As the foaming liquid is injected, the two sets of telescopic cylinders 33 gradually extend. When the foaming liquid injection is completed, the two sets of telescopic cylinders 33 drive the foaming box 38 to a horizontal position.

[0059] By utilizing the hinged relationship between two sets of telescopic cylinders 33 and the mounting base 37, connector 36, and connecting column 35, the tilt angle of the mounting base 37 is changed by the extension and retraction of the cylinders, thereby causing the foaming box 38 to tilt. During injection, the tilted foaming box 38 allows the foaming liquid to flow and diffuse naturally along the inclined surface under the action of gravity. As injection proceeds, the telescopic cylinders 33 gradually extend, and the foaming box 38 is restored to a horizontal position when injection is completed. This design effectively promotes the uniform distribution of foaming liquid, reduces local accumulation, and improves foaming quality through tilted injection. At the same time, the return to a horizontal position after injection provides a stable foundation for subsequent foaming and molding, reduces manual intervention, and improves production efficiency and process stability.

[0060] Since the foaming component 3 is controlled to move by four sets of guide wheels 32, it is easy to cause positional deviation when the foaming component 3 is placed in the position of the auxiliary component 5. Therefore, the position of the foaming component 3 is limited by the setting of the limiting component 4, so that the foaming component 3 can be more easily adapted to the auxiliary component 5.

[0061] The specific structure of the limiting component 4 is as follows: See Figure 2 The limiting component 4 includes a mounting platform 41, and two sets of guide rails 42 are symmetrically arranged on the top of the mounting platform 41.

[0062] When the foaming component 3 is pushed to the position of the limiting component 4, the four sets of guide wheels of the foaming component 3 move along the two sets of guide rails 42. The guide rails 42 limit the movement trajectory of the guide wheels 32, ensuring that the foaming component 3 maintains a straight line during the pushing process, reducing collisions or misalignments with surrounding equipment caused by deviation. At the same time, since the foaming component 3 moves in a straight line, it is easier to determine the position of the foaming component 3, which is conducive to the cooperation between the auxiliary component 5 and the foaming component 3.

[0063] In addition, a chamfer is provided at the end of the mounting platform 41, and a chamfer is provided at the position where it contacts the guide wheel 32. By providing the chamfer, the right-angle collision and jamming between the guide wheel 32 and the mounting platform 41 can be reduced.

[0064] If the edge of the mounting platform 41 is a right angle, the guide wheel 32 of the foaming component 3 is prone to resistance or even jamming when it approaches or contacts the edge due to the obstruction of the sharp corner; the chamfered design transforms the right angle into an inclined transition surface, and the guide wheel 32 can smoothly cut into the mounting platform 41 along the chamfer, reducing frictional resistance and making the pushing process smoother.

[0065] Once the position of the foaming component 3 is determined, the structure of the auxiliary component 5 needs to be designed to make the auxiliary component 5 compatible with the foaming component 3.

[0066] The specific structure of auxiliary component 5 is as follows: See Figure 6 and Figure 7 The auxiliary component 5 includes a connecting plate 51, a pressure plate 52 is provided below the connecting plate 51, two sets of limiting structures 55 are symmetrically provided on the top of the pressure plate 52, and a set of snap-fit ​​mechanisms 54 are provided above the two sets of limiting structures 55 respectively. The limiting structures 55 and the snap-fit ​​mechanisms 54 are adapted to each other.

[0067] See Figure 6 and Figure 7 Two sets of adjusting cylinders 53 are symmetrically arranged on the top of the connecting plate 51. The two sets of adjusting cylinders 53 are arranged diagonally. Two sets of connecting seats 56 are symmetrically arranged below the connecting plate 51. The output ends of the two sets of adjusting cylinders 53 pass through the connecting plate 51 and are connected to the two sets of connecting seats 56 respectively.

[0068] A tripod is provided on one side of the connecting seat 56, and the locking mechanism 54 is located inside the tripod. The connecting plate 51 and the pressure plate 52 can be connected together by adjusting the cylinder 53, the connecting seat 56, the locking mechanism 54, and the limiting structure 55. Therefore, when the connecting plate 51 moves, the pressure plate 52 can follow the connecting plate 51 to move due to the limitation of the above structure.

[0069] When the pressure plate 52 moves to the top of the foaming box 38 and covers the foaming box 38, the pressure plate 52 and the foaming box 38 cooperate to form a closed space. In the closed environment, when the foaming material expands, it will form a stable pressure in the mold. This pressure will cause the material to fill the mold.

[0070] The foaming box 38 has a groove around its top, and the pressure plate 52 has a flange around its edge. The flange of the pressure plate 52 is adapted to the groove on the top of the foaming box 38. At the same time, a silicone sealing ring is provided inside the groove to achieve a seal. The flange is angled to facilitate quick insertion and removal. In practical applications, when the pressure plate 52 moves to the top of the foaming box 38, the transfer component 1 continues to move the pressure plate 52 downward. At this time, the flange is inserted into the groove to achieve a seal. After foaming is completed, the transfer component 1 can lift the pressure plate 52. At this time, the flange disengages from the groove, realizing the separation of the pressure plate 52 from the foaming box 38.

[0071] However, during the foaming process, the material will generate expansion pressure, which will put pressure on the pressure plate 52. Therefore, the pressure plate 52 needs to be designed accordingly.

[0072] By setting crisscrossing reinforcing ribs on the surface of the pressure plate 52, the ability of the pressure plate 52 to resist expansion pressure is enhanced. The crisscrossing ribs divide the surface of the pressure plate 52 into multiple small area units, so that the pressure is evenly distributed to the connection between the ribs and the substrate, reducing local stress and dispersing the pressure load of the pressure plate 52 during foaming.

[0073] In Example 2, foaming can be performed using the above structure. However, during the process of covering the top of the foaming box 38 with the pressure plate 52, air may be drawn into the foaming box 38. The air forms new large bubbles on the surface or inside the liquid. At this time, after covering with the pressure plate 52, it is necessary to shake the foaming box 38 and the pressure plate 52 as a whole immediately. Immediate shaking can cause the large bubbles to break into small bubbles or allow the bubbles to escape from the liquid surface, reducing the risk of voids and cracks in the foam.

[0074] In order to achieve the above-mentioned purpose of shaking the pressure plate 52 and the foaming box 38, the pressure plate 52 needs to be designed so that the pressure plate 52 and the foaming box 38 can shake simultaneously.

[0075] The shaking of the pressure plate 52 and the foaming box 38 is mainly caused by the shaking of the foaming box 38, which in turn drives the pressure plate 52 to shake. The shaking of the foaming box 38 is caused by the telescopic cylinder 33.

[0076] The pressure plate 52 moves along with the foaming box 38 as it shakes. Since the pressure plate 52 needs to be adjusted in position by the connecting plate 51, the middle position between the pressure plate 52 and the connecting plate 51 needs to be designed.

[0077] By adding a connecting component between the pressure plate 52 and the connecting plate 51, it can be connected to the connecting plate 51 while the auxiliary pressure plate 52 is swaying.

[0078] The specific structure is as follows: See Figure 6 and Figure 7 A telescopic rod 58 is provided at the middle position of the two sets of connecting seats 56. A first hinge post 57 is provided at one end of the telescopic rod 58. One end of the first hinge post 57 is hinged to the telescopic rod 58, and the other end of the first hinge post 57 is fixedly connected to the connecting plate 51. A second hinge post 59 is provided at the other end of the telescopic rod 58. One end of the second hinge post 59 is hinged to the telescopic rod 58, and the other end of the second hinge post 59 is fixedly connected to the pressure plate 52.

[0079] The telescopic rod 58 is a tool that achieves free telescopic function through a nested tubular structure design. The main body of the telescopic rod 58 is composed of multiple nested hollow tubes with positioning holes in the tube body. The telescopic length is locked by a pin, ensuring that an adjustable hinge linkage structure is formed between the connecting plate 51 and the pressure plate 52. It can adapt to the distance change requirements when moving by changing the distance between the two connection points through telescopic extension, and can also adapt to the movement requirements of different angles by rotating the hinge columns at both ends.

[0080] The process of shaking immediately after the pressure plate 52 is covered is as follows: By utilizing the hinged relationship between the two sets of telescopic cylinders 33 and the mounting base 37, the connecting piece 36, and the connecting column 35, the extension and retraction of the cylinders can cause the mounting base 37 to shake, thereby causing the foaming box 38 to shake. Then, by utilizing the hinged relationship between the second hinge column 59, the telescopic rod 58, and the first hinge column 57, as well as the connection relationship between the first hinge column 57 and the connecting plate 51, and between the second hinge column 59 and the pressure plate 52, the pressure plate 52 can shake along with the foaming box 38 under the shaking. The pressure plate 52 can produce the same movement as the foaming box 38, so as to achieve the purpose of shaking after the pressure plate 52 covers the foaming box 38.

[0081] During the above process, the shaking of the foaming box 38 and the pressure plate 52 is rapid and gentle. If the shaking amplitude is large, it will affect the sealing relationship between the foaming box 38 and the pressure plate 52.

[0082] In addition, since the pressure plate 52 and the connecting plate 51 are connected by the adjusting cylinder 53, the connecting seat 56, the locking mechanism 54, and the limiting structure 55, the locking mechanism 54 and the limiting structure 55 need to be designed in detail so that they can meet the needs of the pressure plate 52 to shake.

[0083] By rapidly shaking the foaming box 38 and the pressure plate 52, the generation of large bubbles can be reduced. At the same time, the shaking can ensure that the components of the foaming liquid come into full contact, ensuring that the chemical reaction proceeds synchronously throughout the whole process and reducing local over-reaction or incomplete reaction.

[0084] The specific structure of the card-connecting mechanism 54 is as follows: See Figure 8 The clamping mechanism 54 includes a clamping cylinder 541, and the output end of the clamping cylinder 541 is provided with two sets of grippers 542, and the grippers 542 are L-shaped.

[0085] The specific structure of the limiting structure 55 is as follows: See Figure 8 The limiting structure 55 includes a buckle 551. A buckle groove 552 is provided at the middle of the bottom of the buckle 551. Two sets of uprights 553 are symmetrically arranged at the bottom of the buckle 551. One end of the uprights 553 is connected to the buckle 551, and the other end of the uprights 553 is connected to the pressure plate 52.

[0086] Among them, the L-shaped gripper 542 is adapted to the slot 552. When the gripping cylinder 541 is activated, the gripping cylinder 541 can drive the two sets of grippers 542 to tighten and loosen.

[0087] When the pneumatic clamping cylinder 541 opens the two sets of grippers 542, the adjusting cylinder 53 is activated. The adjusting cylinder 53 drives the snap-fit ​​mechanism 54 to move upward through the connecting seat 56. At this time, the two sets of grippers 542 are in a snap-fit ​​state with the two sets of slots 552, that is, the pressure plate 52 and the connecting plate 51 are in a connected state.

[0088] By activating the adjusting cylinder 53, the connecting seat 56 is moved downward. The connecting seat 56 further moves the locking mechanism 54 downward. At this time, the two sets of grippers 542 move away from the two sets of slots 552. Then, by activating the clamping cylinder 541, the two sets of grippers 542 are in a tightened state. At this time, the two sets of grippers 542 move away from the two sets of latches 551. That is, the locking mechanism 54 moves away from the limiting structure 55. The limiting structure 55 and the locking mechanism 54 do not contact each other and there is a gap between them. By setting this gap, the movement space of the pressure plate 52 is provided to meet the shaking requirements of the pressure plate 52.

[0089] The opening and closing of the gripper 542 is controlled by the pneumatic clamping cylinder 541, and the up and down movement of the adjusting cylinder 53 is coordinated to achieve engagement or disengagement with the limiting structure 55. When the clamping cylinder 541 opens the gripper 542, and the adjusting cylinder 53 drives the engagement mechanism 54 to move upward, the gripper 542 engages with the slot 552 of the limiting structure 55, making the pressure plate 52 and the connecting plate 51 rigidly connected. When the adjusting cylinder 53 drives the engagement mechanism 54 to move downward, and the gripper 542 moves away from the slot 552 and tightens, the engagement mechanism 54 disengages from the limiting structure 55, forming a gap.

[0090] The locking mechanism is achieved by the cooperation of the slot 552 and the gripper 542. After the locking mechanism 54 moves down and disengages, the gap between the two provides space for the pressure plate 52 to swing. The buckle 551 serves as a positioning reference to ensure that the gripper 542 maintains a safe distance from the limiting structure 55 when it is tightened. This allows the pressure plate 52 to swing freely within the gap range, meeting the dynamic adjustment requirements.

[0091] Example 3: A method for operating an auxiliary device for skylight foaming injection, using any one of the auxiliary devices for skylight foaming injection, includes the following steps: S1. First, place the foaming component 3 at the position of the limiting component 4 and adjust the foaming component 3 to be in an inclined state.

[0092] S11. When the foaming component 3 is pushed to the position of the limiting component 4, the four sets of guide wheels of the foaming component 3 move along the two sets of guide rails 42. After moving to the processing position, the brake pedal of the guide wheel 32 is pressed, and the wheel is locked by the brake pad to determine the position of the foaming component 3.

[0093] S12. After the initial position of the foaming component 3 is determined, the two sets of telescopic cylinders 33 are activated. Under the drive of the two sets of telescopic cylinders 33, the mounting base 37 is in an inclined state, and the foaming box 38 connected to the mounting base 37 is also in an inclined state. That is, the foaming component 3 is in an inclined state, and the two sets of telescopic cylinders 33 are in a retracted state.

[0094] S2. Next, after the position of the foaming component 3 is determined, foaming liquid is injected into the interior of the foaming component 3 through the injection component 2. Following the injection of the injection component 2, the foaming component 3 gradually adjusts its tilted state. When the foaming liquid injection is completed, the foaming component 3 is adjusted to a flat state.

[0095] S21. Next, after the position of the foaming component 3 is determined, the transfer electric slide rail 22 is started. The transfer electric slide rail 22 drives the injection mechanism 21 to move horizontally to the position of the foaming box 38. The robotic arm of the injection mechanism 21 controls the injection head to penetrate into the foaming box 38, and the injection head begins to inject foaming liquid.

[0096] S22. Since the foaming box 38 is in an inclined state, the foaming liquid can flow from one side of the foaming box 38 along the inclined surface to the other side, realizing the flow and diffusion of the foaming liquid. As the foaming liquid is injected, the two sets of telescopic cylinders 33 gradually extend. When the foaming liquid is injected, the two sets of telescopic cylinders 33 drive the foaming box 38 to be placed in a horizontal position.

[0097] S3. Then, after the foaming component 3 is in a flat state, the position of the auxiliary component 5 is immediately adjusted by the transfer component 1 so that the auxiliary component 5 is opposite to the foaming component 3 and the auxiliary component 5 is placed on top of the foaming component 3.

[0098] S31. Then, after the foaming component 3 is in a flat state, the first electric slide rail 12 is immediately activated. The first electric slide rail 12 drives the bracket 13, the second electric slide rail 14, the third electric slide rail 15 and the auxiliary component 5 to move horizontally in the front and back directions. Further, the second electric slide rail 14 is activated. The second electric slide rail 14 drives the third electric slide rail 15 and the auxiliary component 5 to move horizontally in the left and right directions. Finally, the third electric slide rail 15 is activated. The third electric slide rail 15 drives the auxiliary component 5 to move vertically in the up and down directions, thereby adjusting the position of the auxiliary component 5 to correspond with the position of the foaming component 3.

[0099] 32. During the overall position adjustment of auxiliary component 5, the connecting plate 51 included in auxiliary component 5 and the pressure plate 52 connected to the connecting plate 51 follow the position adjustment, and finally realize the correspondence between the pressure plate 52 and the position of the foaming box 38.

[0100] S33. When the pressure plate 52 moves to the top of the foaming box 38, the pressure plate 52 continues to move down through the transfer assembly 1. At this time, the flange is inserted into the groove to achieve a seal.

[0101] S4. After the auxiliary component 5 is placed on top of the foaming component 3, immediately shake the foaming component 3 and the auxiliary component 5 quickly and gently again. After shaking is complete, the foaming liquid begins to foam. After foaming is complete, start the transfer component 1 to drive the auxiliary component 5 to detach from the foaming component 3.

[0102] S41. After the pressure plate 52 is placed on the foaming box 38, immediately adjust the cylinder 53 to drive the snap-fit ​​mechanism 54 to move down. When the gripper 542 moves away from the slot 552 and tightens, the snap-fit ​​mechanism 54 and the limiting structure 55 disengage, forming a gap.

[0103] S42. Immediately start the two sets of telescopic cylinders 33 to drive the foaming box 38 to achieve rapid and gentle shaking. Since the pressure plate 52 and the foaming box 38 are connected at this time, and the pressure plate 52 and the connecting plate 51 are only connected by a hinge mechanism, the pressure plate 52 can shake with the foaming box 38 without affecting the seal.

[0104] S43. After shaking is complete, the foaming liquid begins to foam. After the foaming is completed, the pressure plate 52 can be lifted by the transfer component 1. At this time, the flange disengages from the groove, realizing the separation of the pressure plate 52 from the foaming box 38.

[0105] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
