Description

Technical Field

[0001] This invention relates to the field of curtain wall conveying technology, and in particular to a conveying device for a curtain wall adhesive injection production line. Background Technology

[0002] In curtain wall production, the glue injection process is a key step in ensuring the airtightness, watertightness, and structural safety of the curtain wall panels. The accuracy and efficiency of the conveying device directly affect the glue injection quality and production cycle.

[0003] Currently, commonly used conveying devices in curtain wall adhesive injection production lines include fixed roller conveyors and belt conveyors. Fixed roller conveyors consist of several parallel conveyor rollers, relying on the sliding friction between the rollers and the bottom of the curtain wall panels to move the workpiece. They have a simple structure and high load-bearing capacity, but are usually arranged in a straight line, and the workpiece is in direct contact with the rollers, making it difficult to achieve the cyclical use of independent carriers. Belt conveyors, on the other hand, carry the workpiece using a circular belt. The return section of the belt is generally located directly below the conveyor line, not occupying additional floor space. However, the belt itself is a continuous unit, making it difficult to flexibly adapt to curtain wall panels of different sizes or achieve modular reconstruction.

[0004] With the increasing demands for flexibility and compactness in industrialized construction, some high-end curtain wall production lines have begun to use a method of sequentially assembling multiple independent load-bearing units (carriers) to transport curtain wall panels, and returning empty carriers to the starting point for reuse after unloading. In this cyclical transport mode, the working channel is used to carry curtain wall panels from the starting point to the ending point, while empty carriers need to return via another channel (return channel). In existing technologies, the return channel usually needs to maintain the same width as the working channel to meet the passage requirements of the carriers in their folded state, resulting in a large footprint for the entire production line and making it difficult to flexibly adjust the layout to high-density forms such as U-shapes or serpentine patterns. In addition, the space occupied by the carriers during the empty return trip cannot be reduced, further limiting the compact design of the production line.

[0005] Therefore, there is an urgent need to develop a curtain wall adhesive delivery device that can reduce the width of the unloaded return passage and improve the layout flexibility, so as to meet the needs of high-end equipment manufacturing for intensive and flexible production lines. Summary of the Invention

[0006] In order to overcome the problems mentioned in the background art, the present invention provides a conveying device for a curtain wall adhesive injection production line.

[0007] The technical implementation of this invention is: a conveying device for a curtain wall adhesive injection production line, comprising: A support frame is installed on the ground. The support frame has two symmetrically distributed first guide grooves and two symmetrically distributed baffles are fixed to the support frame. Multiple support rods are placed on the support frame. Each support rod is rotatably equipped with two symmetrically distributed rotating frames. Each rotating frame is rotatably equipped with multiple rotating wheels, which are located within the first guide groove. A guide frame is installed on the ground. The guide frame has a second guide groove, which is divided into two horizontal grooves and one inclined groove.

[0008] Preferably, an elastic pad is provided on the side of the support rod away from the rotating frame.

[0009] Preferably, elastic blocks are installed at both ends of the support rod.

[0010] Preferably, the support rod is slidably provided with a first sliding frame, and a spring is fixedly connected between the first sliding frame and the support rod. The first sliding frame is provided with a handle.

[0011] Preferably, a first transmission belt is wound around the two rotating frames on the same support rod via a transmission wheel, for the two rotating frames to rotate synchronously.

[0012] Preferably, the first sliding frame is fixedly connected to a rack, and the rotating frame near the rack is fixedly connected to a one-way gear, with the rack meshing with the one-way gear.

[0013] Preferably, the support rod is fixedly connected to a fixing block, the fixing block is slidably provided with a second sliding frame, the second sliding frame is fixedly connected to the fixing block with a spring, the rotating frame near the second sliding frame is fixedly connected to a support block, the second sliding frame is used to press the support block, and the side wall of the support block is rectangular.

[0014] Preferably, the system further includes multiple positioning units, each positioned on a corresponding rotating frame. Each positioning unit connects two adjacent rotating frames on two adjacent support rods. Each positioning unit includes: A magnetic block is embedded in one side of the rotating frame; A magnetic driven rod is slidably disposed on the other side of the rotating frame. A tension spring is fixed between the magnetic driven rod and the rotating frame. The magnetic block is used to attract the corresponding magnetic driven rod to move, so that the magnetic driven rod spans across the contact point of the corresponding two rotating frames in two adjacent support rods.

[0015] Preferably, the rotating frame has the inclined groove, which is used to correspond to the vertical movement of the magnetic driven rod.

[0016] Preferably, the system further includes multiple speed control units, each of which is respectively disposed on a corresponding rotating frame. Each speed control unit includes: A rotating component is rotatably mounted on the rotating frame. The rotating component and the adjacent rotating wheel are connected by a second transmission belt wound around a transmission wheel for synchronous rotation. Multiple sliding blocks, equidistant from each other in the circumferential direction, are slidably disposed within the rotating component, and a tension spring is fixedly connected between the sliding blocks and the rotating component; A fixed ring is fixed to the rotating frame. The central axis of the fixed ring coincides with the central axis of the rotating component. The sliding block is used to contact the inner surface of the fixed ring, and the inner surface of the fixed ring is provided with a rough structure to increase friction.

[0017] The present invention has the following advantages: 1. Compact structure and high space utilization: Multiple support rods are used to splice and support the curtain wall panels for continuous transport. A rotating and folding mechanism between the support rods and the rotating frame allows the transport vehicle to fold into a compact state parallel to the rods during the unloaded return trip, significantly reducing the width requirement of the return passage. This design overcomes the limitations of traditional conveyor lines where the working and return sections occupy space in parallel, allowing the entire glue-dispensing production line to be flexibly arranged in a U-shape or high-density configuration. This significantly improves the effective output per unit area of ​​the factory floor, meeting the stringent requirements of the high-end equipment manufacturing industry for intensive and flexible production line layouts.

[0018] 2. Stable connection and high conveying accuracy: When adjacent support rods are attached, magnetic blocks are used to attract magnetic driven rods to form a mechanical locking structure across the attachment surface, so that adjacent support rods can move synchronously with a rigid connection, effectively avoiding disengagement or misalignment caused by uneven push and pull forces during the conveying process; at the same time, the lateral limiting effect of the magnetic driven rods can significantly suppress the left and right swaying of adjacent support rods in the width direction, greatly improving the stability and positioning accuracy of the curtain wall panels during continuous conveying.

[0019] 3. Automatic speed control and excellent glue injection quality: Through the centrifugal friction damping mechanism of the sliding block inside the rotating part and the linkage with the rotating wheel, when the moving speed is too fast, the sliding block presses against the rough inner wall of the fixed ring to generate friction and limit the rotation speed. This allows the support rod to automatically adjust to a uniform and stable state when passing through the glue injection station, regardless of whether it is subjected to thrust fluctuations or gravity. This effectively avoids uneven glue layer thickness, glue leakage or glue accumulation caused by sudden speed changes, and significantly improves the uniformity and appearance quality of the glue coating.

Detailed Implementation

[0022] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example 1

[0023] A conveying device for a curtain wall adhesive injection production line is suitable for precision conveying and flexible layout of building curtain wall production lines in the field of high-end equipment manufacturing.

[0024] like Figures 1-7 As shown, the device includes a support frame 2, which is fixedly installed on the working ground. Two first guide grooves 3 are provided on its upper surface along the length direction, and upward protruding baffles 4 are fixedly connected to the two side edges of the support frame 2, which are used to limit and guide the conveying components laterally.

[0025] Multiple support rods 5 are arranged horizontally on the support frame 2 to form a modular load-bearing unit. An elastic pad is laid on the upward-facing surface of each support rod 5 to ensure seamless contact and shock absorption of the high-end curtain wall panels during transport. Elastic blocks 501 are also installed at both ends of each support rod 5 to provide end cushioning during return, reducing production line noise and extending equipment lifespan. A rotating frame 6 is rotatably connected to each support rod 5 near both ends. The rotating frame 6 can be angled relative to the support rod 5 to switch between folded states. Two rotating wheels 7 are rotatably installed within each rotating frame 6. The rims of the wheels 7 are embedded in the corresponding first guide groove 3 and can roll smoothly within the groove, providing a low-resistance motion pair for the precise transfer of curtain wall panels between the adhesive injection stations.

[0026] The guide frame 8 is also fixed to the ground and located on one side of the support frame 2, used to construct a compact spatial return channel for the transport vehicle. The guide frame 8 is machined with a second guide groove 9. The trajectory of the second guide groove 9 is formed by connecting two horizontally oriented groove segments at the front and rear and an inclined groove 19 with a height difference in the middle, so as to guide the support rod 5 to complete the vertical attitude change and spatial avoidance.

[0027] A first sliding frame 10 is slidably mounted on each support rod 5. A return spring in a compressed state is provided between the first sliding frame 10 and the support rod 5. The first sliding frame 10 also has an integrally formed or fixed handle for easy gripping by the operator, to meet the needs of rapid operation in a human-machine collaborative environment. A transmission wheel is provided on each of the two rotating frames 6 at both ends of the same support rod 5. The two transmission wheels are connected by a first transmission belt 11, so that the two rotating frames 6 can rotate synchronously, thereby ensuring the consistency and reliability of the vehicle's attitude changes. A rack 12 is fixedly connected to the first sliding frame 10, and a one-way gear 13 is coaxially fixed to the rotating frame 6 adjacent to the rack 12. The rack 12 and the one-way gear 13 mesh and drive each other, forming a purely mechanical gravity-driven folding mechanism. State switching can be completed without additional electrical power, which aligns with the green energy-saving and cost-reduction technology orientation in high-end equipment manufacturing.

[0028] A fixing block 14 is also fixedly installed on the support rod 5. A second sliding frame 15 is slidably installed in the fixing block 14 along the horizontal direction. A thrust spring abuts between the second sliding frame 15 and the fixing block 14. A support block 16 is fixedly connected to the rotating frame 6 corresponding to the position of the second sliding frame 15. The end of the second sliding frame 15 is pressed against the side wall of the support block 16 under the action of the spring. The circumferential side wall of the support block 16 is rectangular, which is used to cooperate with the second sliding frame 15 to form a stable positioning and holding of the rotating frame 6 at the folding or unfolding angle, ensuring that the conveyor has high repeatability positioning accuracy in different work positions.

[0029] Specific working principle: When using this device for curtain wall adhesive injection production, in the initial state, all support rods 5 are placed horizontally on the support frame 2, and the rotating wheel 7 is positioned in the first guide groove 3 opened on the support frame 2, with adjacent support rods 5 in contact. Then, the operator places the curtain wall panel to be injected with adhesive on top of all support rods 5. When the support rods 5 are pushed, the rotating wheel 7 rolls along the first guide groove 3 to achieve horizontal conveying of the curtain wall panel. When the curtain wall panel passes through the adhesive injection station, the adhesive injection unit 1 sprays adhesive evenly onto the surface of the curtain wall panel. The adhesive injection stops after the curtain wall panel has completely passed through, and stops after the support rods 5 move to the conveying limit position, at which point the curtain wall panel can be transferred to the subsequent processing stage.

[0030] After the curtain wall panels are glued and unloaded, the operator holds the handle of the first sliding frame 10 on the last support rod 5 and lifts it up. Under the gravity of the support rod 5, the first sliding frame 10 slides downward relative to the support rod 5 and compresses the spring between them. During this relative movement, the rack 12 fixed to the first sliding frame 10 drives the one-way gear 13 meshing with it to rotate. The one-way gear 13 drives the adjacent rotating frame 6 to rotate 90°. At the same time, under the transmission action of the first transmission belt 11, the two rotating frames 6 at both ends of the same support rod 5 rotate synchronously to a folded state parallel to the support rod 5.

[0031] During the rotation of the rotating frame 6 with the support block 16 installed, the support block 16 first overcomes the spring force to push the second sliding frame 15 away. After rotating 90° to the position, the second sliding frame 15 resets under the elastic force of the spring it is connected to and presses against the rectangular side wall of the support block 16 again, thereby locking the rotating frame 6 in a folded posture parallel to the support rod 5. Then the support rod 5 is transferred and placed on the guide frame 8, so that the rotating wheel 7 falls into the second guide groove 9. At this time, the operator releases the first sliding frame 10. Under the action of the spring reset force, the first sliding frame 10 drives the rack 12 to return. During this process, the one-way gear 13 is in a slipping state relative to the rack 12 and cannot drive the rotating frame 6 to reverse. Then the support rod 5 is pushed forward along the guide frame 8. The spatial return from the end of the conveying to the front of the conveying is achieved by using the guide of the inclined section of the second guide groove 9 (of course, the return movement of the support rod 5 on the guide frame 8 can also be assisted by the push rod motor or chain drive mechanism installed on the side of the guide frame 8 to reduce manual intervention).

[0032] When the return stroke is completed, the elastic block 501 impacts the front end of the support frame 2 or the corresponding limiting structure to provide buffer protection. Then, the operator holds the first sliding frame 10 again to lift the support rod 5 and repeats the above lifting action to make the rotating frame 6 rotate 90° again to return to the working state perpendicular to the support rod 5. Then, it is placed back into the first guide groove 3 of the support frame 2 to complete one complete cycle of conveying operation.

[0033] In the above-mentioned curtain wall adhesive injection process, the continuous conveying of curtain wall panels is achieved by splicing multiple support rods 5, resulting in a compact structure. At the same time, the rotation and folding mechanism between the support rods 5 and the rotating frame 6 significantly reduces the space occupied by the conveying vehicle during the return trip, thereby achieving efficient recycling of the conveying equipment within a small space. Example 2

[0034] Based on Example 1, such as Figure 7 and Figure 8 As shown, this device also includes multiple positioning units, each corresponding to the side of each rotating frame 6, used to achieve a detachable connection between the corresponding rotating frames 6 on two adjacent support rods 5. Specifically, each positioning unit includes: a magnetic block 17, embedded and fixed within one end face of the rotating frame 6; and a magnetic driven rod 18, slidably inserted into the side wall of another adjacent rotating frame 6, with a tension spring connecting the magnetic driven rod 18 to the housing of the rotating frame 6 to provide a reset force. When the end faces of two adjacent rotating frames 6 are in contact, the magnetic attraction force generated by the magnetic block 17 overcomes the tension spring and pulls the magnetic driven rod 18 out from one side, causing the rod of the magnetic driven rod 18 to laterally cross the joint between the two rotating frames 6, thus forming a mechanical barrier and a rigid connection. Correspondingly, the rotating frame 6 is also provided with an inclined groove 19. When the magnetic driven rod 18 tilts with the support rod 5, it can generate a vertical displacement in the inclined groove 19 to help disengage the magnetic connection, reduce the difficulty of manual unlocking, and meet the requirements of fast cycle time in continuous production.

[0035] Specific working principle: When the two rotating frames 6 corresponding to the two adjacent support rods 5 are in contact with each other, the magnetic block 17 on one side of the rotating frame 6 attracts the magnetic driven rod 18 that is slidably disposed in the other side of the rotating frame 6 under the magnetic attraction. The magnetic driven rod 18 overcomes the tension of the connected tension spring and generates lateral displacement, and finally spans across the contact surface of the two adjacent rotating frames 6 to form a reliable mechanical locking structure. Under the attraction and holding effect of the magnetic block 17 and the magnetic driven rod 18, the adjacent support rods 5 are rigidly connected so that they can move synchronously back and forth, effectively avoiding the phenomenon of adjacent support rods 5 being disengaged or misaligned due to uneven push and pull forces during the conveying process. At the same time, the lateral limiting effect of the magnetic driven rod 18 can significantly suppress the left and right movement and swaying between the two adjacent support rods 5 in the width direction, greatly improving the stability and positioning accuracy of the curtain wall panel during continuous conveying.

[0036] After the conveying stroke is completed, the operator holds the handle of the first sliding frame 10 and moves the support rod 5 to tilt it to a certain extent. At this time, the magnetic driven rod 18 swings under the guidance of the tilting groove 19, thereby helping to overcome the magnetic attraction of the magnetic block 17 and easily separate the two, reducing the difficulty and labor intensity of manual unlocking. Then, repeat the above operation to smoothly transfer the support rod 5 to the guide frame 8 for subsequent return cycle. Example 3

[0037] Based on Example 2, such as Figure 4 , Figure 8 and Figure 9 As shown, the device also includes multiple speed control units, which are integrated on the side of each rotating frame 6 to form a passive adaptive speed regulation system. The speed control unit includes: a rotating component 20, which is rotatably supported on the housing of the rotating frame 6 by bearings. The axle of the rotating component 20 is connected to the axle of the adjacent rotating wheel 7 by a transmission wheel and a second transmission belt 21, so that the rotating component 20 can rotate synchronously with the rotating wheel 7; a plurality of sliding blocks 22, which are circumferentially spaced and equidistantly installed in the internal cavity of the rotating component 20 along the radial direction. Each sliding block 22 is connected to the rotating component 20 by a tension spring to provide a preload for centripetal contraction; and a fixed ring 23, which is fixedly installed on the rotating frame 6 and arranged coaxially with the rotating component 20. The outer end face of the sliding block 22 can extend outward under the action of centrifugal force and fit against the inner ring surface of the fixed ring 23. The inner ring surface of the fixed ring 23 is roughened to increase the coefficient of friction, for example, by knurling, spraying a tungsten carbide wear-resistant coating or forming a non-smooth surface by creating fine grooves. This purely mechanical centrifugal friction structure can adjust the damping torque in real time according to the changes in conveying speed, ensuring that the curtain wall panels pass through the glue injection station at a constant speed, providing a stable motion base for the automated glue coating system, thereby meeting the stringent requirements of high-end equipment manufacturing for the consistency and yield of precision coating processes.

[0038] Specific working principle: During the conveying process, when the rotating wheel 7 rolls, it drives the rotating component 20 to rotate synchronously through the second transmission belt 21 that is wound between it and the transmission wheel of the rotating component 20. Multiple sliding blocks 22 evenly distributed in the inner circumference of the rotating component 20 are thrown outward under the action of centrifugal force to overcome the tension of the connected tension spring. When the support rod 5 is pushed by an external force and moves too fast, the rotation speed of the rotating wheel 7 increases sharply. At this time, the centrifugal force on the sliding block 22 increases significantly, making it press more tightly against the rough inner surface of the fixed ring 23 fixed to the rotating frame 6, and a continuous and stable sliding friction force is generated between the two.

[0039] Under the action of this rotational damping, the rotational speed of the rotating part 20 is effectively suppressed, and then the rolling speed of the wheel 7 is restricted in the opposite direction through the second transmission belt 21. This follow-up damping mechanism enables the support rod 5 to automatically adjust to a uniform and stable motion state when passing through the glue injection station, regardless of whether it is subjected to thrust fluctuations or is in a downward trend due to gravity.

[0040] Thanks to this, the curtain wall panels move at a uniform speed without any jerking when passing through the glue injection unit 1, which effectively avoids uneven glue thickness, glue leakage or glue piling caused by sudden changes in speed. This significantly improves the uniformity and appearance quality of the glue coating, while reducing mechanical impact and noise during the transportation process and extending the service life of the roller 7 and the first guide groove 3.
