Description

Technical Field

[0001] This utility model relates to the field of heat dissipation pipe processing technology, and in particular to a rubber coating device for bending equipment. Background Technology

[0002] A heat pipe is a heat transfer device specifically designed for efficient heat dissipation. It is typically made of a material with high thermal conductivity and contains tiny channels that allow fluid to flow through and carry away heat. This design makes heat pipes crucial in electronic devices, machinery, and other applications requiring heat dissipation.

[0003] During the bending process of heat dissipation pipes, multiple heat dissipation pipes are usually arranged vertically and fixed on the bending mechanism for simultaneous processing. However, because the front end of the pipe is prone to spreading out, microscopic misalignment occurs at the bending point, leading to increased assembly deviations in the later stages, which in turn increases assembly difficulty and defect rate.

[0004] To address these issues, the current solution involves manually binding the heat sink pipes with cable ties before bending. However, due to the large size of the turntable assembly, workers must lie prone on it to perform the binding work, leading to inconvenience, low efficiency, and significant safety hazards. Furthermore, uneven binding force during manual work can result in inconsistent tightness, affecting bending accuracy and product quality. Utility Model Content

[0005] The technical problem to be solved by this utility model is: in order to solve the problems of low efficiency, inconvenient operation and unstable binding quality of existing manual binding, this utility model provides a rubber coating device for bending equipment, which sets a rubber coating mechanism to replace manual binding, realizes automatic fixing of heat dissipation pipes, improves the stability and consistency of bending processing, reduces labor intensity and improves production efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a rubber coating device for bending equipment, including a machine tool and a rubber coating mechanism. The front end of the machine tool is rotatably mounted with a turntable assembly for supporting heat dissipation pipes. A through movable groove is opened in the center of the turntable assembly. The rubber coating mechanism is movably arranged in the center of the turntable assembly. The coating mechanism includes a glue feeding component and a glue pressing component. The glue feeding component is located in a movable groove and moves horizontally back and forth to pull the tape. The glue pressing component is located in a movable groove and moves vertically back and forth to press the tape tightly onto the outer periphery of the heat sink tube bundle. Thus, precise tape feeding and pressing are achieved through mechanical automation, avoiding the instability of manual operation and significantly improving the uniformity and reliability of the coating, thereby ensuring stability and processing accuracy during the heat sink tube bending process. Simultaneously, the automated coating process greatly shortens operation time, reduces human intervention, effectively lowers safety hazards, and improves overall production efficiency.

[0007] Furthermore, the adhesive feeding assembly includes a clamping cylinder, a gripper located at the output end of the clamping cylinder, and a feeding slide that drives the clamping cylinder to move horizontally; the clamping cylinder clamps the adhesive tape through the gripper, and the feeding slide drives the clamping cylinder to move horizontally to a designated position below the turntable assembly. The adhesive bonding assembly includes a lifting cylinder and a pressure-covering component installed at the piston rod end of the cylinder. The lifting cylinder drives the pressure-covering component to push the adhesive tape upward, so that it fits tightly against the outer periphery of the heat dissipation tube bundle, thus completing the adhesive bonding action.

[0008] Furthermore, the front end of the machine tool is provided with a horizontal support, a vertical support, and an intermediate frame. The vertical support is fixedly sleeved on the front end of the machine tool, the horizontal support is fixed at the bottom of the vertical support, and the lower end of the horizontal support is fixedly connected to the feeding slide. The slide of the feeding slide is connected to the bottom of the clamping cylinder. The rear side of the vertical support is provided with a feeding rack, which is used to place the tape roll and realize continuous feeding. The intermediate frame is fixedly installed on the front end of the machine tool and located below the movable slot. The front side of the intermediate frame is fixedly connected to the cylinder body of the lifting cylinder. Thus, through modular structural design, the components are compactly arranged and work together efficiently, ensuring smooth and stable tape coating operation.

[0009] Furthermore, the turntable assembly includes a chassis and a baffle. The bottom of the chassis is fixedly connected to a vertical support, and a guide and a fixing component are fixedly installed on the top of the chassis. The baffle is fixedly connected to the chassis via a cylinder, and a moving space for clamping cylinder one is formed between the baffle and the chassis. The guide and the fixing component are located between the baffle and the chassis. Thus, the cooperative structure of the baffle and the chassis not only provides stable guidance for the horizontal movement of the clamping cylinder, but also effectively prevents the tape roll from being contaminated by dust during the glue feeding process, ensuring that the tape is clean and dust-free, thereby ensuring the stability of the glue coating quality.

[0010] Furthermore, the guide includes a bracket and a roller. One side of the bracket is fixedly connected to the chassis, and the roller is rotatably mounted on the bracket. The roller is used to guide the direction of the tape during the conveying process. The fixing component includes an L-shaped frame and a clamping cylinder. The horizontal end of the L-shaped frame is fixedly connected to the chassis, and the vertical end is fixedly connected to the cylinder body of the clamping cylinder. The output end of the clamping cylinder is connected to a pressure block. When the tape feeding action is completed, the clamping cylinder drives the pressure block to clamp and fix the tape, fixing the end of the tape to prevent rebound or displacement, and ensuring stable tension during the subsequent tape coating process.

[0011] Furthermore, a guide cylinder is fixedly mounted at the front end of the machine tool. A mounting bracket is fixedly mounted on the piston rod of the guide cylinder, and a shearing assembly is fixedly mounted on one side of the mounting bracket. The shearing assembly moves linearly with the guide cylinder, achieving the tape cutting action. The guide cylinder is located on one side of the guide member, and the shearing assembly is located between the guide cylinder and the guide member, with the shearing blade of the shearing assembly facing the tape conveying path. Thus, the guide cylinder precisely controls the shearing timing and stroke, ensuring accurate tape cutting and avoiding waste and tension imbalance. During the shearing process, the blade quickly closes and immediately resets, with continuous and undelayed action, ensuring the continuity of the tape coating rhythm. The entire system achieves integrated operation of feeding, guiding, clamping, and shearing through precise coordination, with seamless connection between each process, significantly improving the degree of automation and operational reliability.

[0012] Furthermore, the clamping cylinder is linked to the slide of the feeding slide table, and the feeding length of the tape is controlled by the stroke of the slide; the feeding frame is equipped with a tension adjusting roller to maintain constant tension during the unwinding process of the tape and avoid slack or breakage.

[0013] Furthermore, the pressure-covering component is a U-shaped component with its open end facing the turntable assembly and its bottom fixedly connected to the piston rod of the lifting cylinder; buffer pads are symmetrically installed on the inner walls of both sides of the pressure-covering component, and there is a spacing between the buffer pads for placing the heat dissipation pipe; thus, the pressure-covering component moves vertically upward under the drive of the lifting cylinder, so that the buffer pads fit against the outer wall of the heat dissipation pipe, and the force is evenly applied to ensure that the tape tightly wraps the surface of the pipe, while avoiding deformation of the pipe or damage to the tape due to rigid contact; the spacing of the buffer pads is adaptable to heat dissipation pipes of different specifications, improving the versatility of the equipment.

[0014] Furthermore, the inner side of the gripper is provided with inwardly protruding teeth. These teeth maintain the gripping force of the gripper on the tape while reducing the complete adhesion between the tape and the gripper, thus reducing the impact on the tape being moved upward when the subsequent overlay component moves. The teeth are staggered, which enhances the gripping stability, adapts to the conveying requirements of tapes of different thicknesses, and ensures a continuous and reliable overlay process.

[0015] Furthermore, the top of the machine tool is provided with a pipe feeding mechanism for conveying heat dissipation pipes, and the front end of the machine tool is provided with a bending mechanism. The bending mechanism is located at the output end of the pipe feeding mechanism and above the baffle, and is used to bend the heat dissipation pipes.

[0016] Furthermore, the coating mechanism is equipped with a control system, which integrates a PLC controller and a human-machine interface to monitor the operating status of each actuator in real time; it automatically adjusts the clamping force, feeding length and coating stroke through a preset program to adapt to the coating process requirements of various specifications of heat dissipation tubes.

[0017] The beneficial effects of this utility model are as follows: the rubber coating device for bending equipment of this utility model replaces manual binding with a rubber coating process, significantly reducing labor costs and operational errors, and ensuring that the rubber coating position and tension of multiple heat dissipation pipes are highly consistent; its rubber coating process ensures smooth connection of the tape conveying, positioning, cutting and coating processes through the coordinated action of the glue feeding component, the glue pressing component, the shearing component and the covering component; it reduces quality fluctuations caused by human factors and improves product reliability; combined with PLC to precisely control the timing of the actions of each actuator, it achieves seamless connection of processes such as feeding, rubber coating, shearing and bending, and the whole machine operates stably and efficiently.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0027] Example 1: like Figures 1-6 The figure shown is the preferred embodiment of the present invention. A rubber coating device for bending equipment includes a machine tool 1 and a rubber coating mechanism 5. A turntable assembly 4 for supporting heat dissipation pipes is rotatably mounted on the front end of the machine tool 1. A through movable groove 43 is opened in the center of the turntable assembly 4. The rubber coating mechanism 5 is movably arranged in the center of the turntable assembly 4. Reference Figure 2 , Figure 4 , Figure 5 The tape-coating mechanism 5 includes a tape-feeding component and a tape-pressing component 54. The tape-feeding component is located within the movable groove 43 and reciprocates horizontally to pull the tape. The tape-pressing component 54 is located within the movable groove 43 and reciprocates vertically to press the tape tightly onto the outer circumference of the heat sink tube bundle. Thus, through mechanical automation, precise tape delivery and pressing are achieved, avoiding the instability of manual operation and significantly improving the uniformity and reliability of the tape coating, thereby ensuring stability and processing accuracy during the heat sink tube bending process. Simultaneously, the automated tape coating process significantly shortens operation time, reduces human intervention, effectively lowers safety hazards, and improves overall production efficiency.

[0028] in: Reference Figure 2 , Figure 3 The front end of the machine tool 1 is provided with a horizontal support 11, a vertical support 12 and an intermediate frame 13. The vertical support 12 is fixedly sleeved on the front end of the machine tool 1, and the horizontal support 11 is fixed to the bottom of the vertical support 12. The turntable assembly 4 includes a chassis 41 and a baffle 42. The bottom of the chassis 41 is fixedly connected to the vertical support 12, and the top of the chassis 41 is fixedly installed with a guide 551 and a fixing member 552. The baffle 42 is fixedly connected to the chassis 41 through a cylinder, and the guide 551 and the fixing member 552 are located between the baffle 42 and the chassis 41.

[0029] Reference Figures 2-5 The adhesive feeding assembly includes a clamping cylinder 53, a gripper located at the output end of the clamping cylinder, and a feeding slide 52 that drives the clamping cylinder to move horizontally. In this embodiment, the feeding slide 52 adopts conventional technologies such as a screw-driven mechanism or a pneumatic slide, which will not be described in detail here. The lower end of the horizontal support 11 is fixedly connected to the feeding slide 52. The long side of the feeding slide 52 is parallel to the long side of the horizontal support. The slide seat of the feeding slide 52 is connected to the bottom of the clamping cylinder 53. A moving space for the clamping cylinder 53 is formed between the baffle 42 and the chassis 41. The clamping cylinder 53 clamps the tape roll through the gripper. The feeding slide 52 drives the clamping cylinder 53 to move horizontally to a designated position below the turntable assembly 4. A feed rack 51 is provided on the rear side of the vertical support 12. The feed rack 51 is used to place the tape roll and realize continuous feeding. Reference Figure 2 , Figure 6 The adhesive bonding assembly 54 includes a lifting cylinder 541 and a pressing component 542 installed on its piston rod end. The intermediate frame 13 is fixedly installed at the front end of the machine tool 1 and located below the movable groove 43. The front side of the intermediate frame 13 is fixedly connected to the cylinder body of the lifting cylinder 541. The lifting cylinder 541 drives the pressing component 542 to push the adhesive tape upward, so that it is tightly attached to the outer periphery of the heat dissipation tube bundle, thus completing the adhesive bonding action.

[0030] Reference Figure 4 , Figure 5 The guide component 551 includes a bracket and a roller. One side of the bracket is fixedly connected to the chassis 41, and the roller is rotatably mounted on the bracket. The roller is used to guide the direction of the tape during the conveying process. The fixing component 552 includes an L-shaped frame and a clamping cylinder. The horizontal end of the L-shaped frame is fixedly connected to the chassis 41, and the vertical end is fixedly connected to the cylinder body of the clamping cylinder. The output end of the clamping cylinder is connected to a pressure block. When the tape feeding action is completed, the clamping cylinder drives the pressure block to clamp and fix the tape, fix the end of the tape, prevent rebound or displacement, and ensure the tension stability during the subsequent tape wrapping process.

[0031] Reference Figure 5 , Figure 6The front end of machine tool 1 is also fixedly equipped with a guide cylinder 56, similar to the guide cylinders used by Airtac. The piston rod of the guide cylinder 56 is fixedly mounted with a mounting bracket, and a shearing assembly 57 is fixedly mounted on one side of the mounting bracket. This shearing assembly 57 can be implemented using existing pneumatic fingers with blades or pneumatic scissors. Its structure and operation process are conventional technologies and will not be elaborated here. Driven by the guide cylinder 56, the shearing assembly 57 moves linearly to a designated position and then performs the tape cutting action. The guide cylinder 56 is located on one side of the guide member 551, and the shearing assembly 57 is located between the guide cylinder 56 and the guide member 551. The shearing blade of the shearing assembly 57 faces the tape conveying path. Thus, the guide cylinder 56 precisely controls the shearing timing and stroke, ensuring accurate tape cutting and avoiding waste and tension imbalance. During the shearing process, the blade quickly closes and immediately returns to its original position, with continuous and undelayed action, ensuring the continuity of the tape wrapping rhythm. The entire system achieves integrated operation of feeding, guiding, clamping, and shearing through precise coordination, with seamless connection between each process, significantly improving the degree of automation and operational reliability.

[0032] The pressing component 542 is a U-shaped component with its open end facing the turntable assembly 4 and its bottom fixedly connected to the piston rod of the lifting cylinder 541. Thus, the pressing component 542 moves vertically upward under the drive of the lifting cylinder 541, so that the tape adheres to the heat dissipation pipe. Then the heat dissipation pipe enters the interior of the pressing component 542. At this time, the heat dissipation pipe blocks the tape from moving upward, so that the tape is in a U-shaped state, thereby achieving the adhesion of multiple heat dissipation pipes by the tape.

[0033] The aforementioned bending equipment equipped with a coating device further includes: a tube feeding mechanism 2 for conveying heat dissipation tubes is provided at the top of the machine tool 1, and a bending mechanism 3 is provided at the front end of the machine tool 1. The bending mechanism 3 is located at the output end of the tube feeding mechanism 2 and is located above the turntable assembly 4. The turntable assembly also includes a cap-shaped turntable for supporting the aluminum tubes being processed. The turntable is rotatably mounted on the chassis, and the center of the turntable is rotatably mounted with the side of the baffle. A drive gear driven by a guide cylinder is provided at the top of the machine tool, and the drive gear meshes with the side wall of the turntable. Two baffles are provided, and the two baffles are symmetrically arranged to form a circular disc, which is laid flat above the chassis.

[0034] The bending equipment performs multiple bends on the heat dissipation pipe material, forming it into a single piece. The process is as follows: Multiple heat dissipation pipes are simultaneously conveyed by the pipe feeding mechanism 2 through the bending mechanism 3 and enter the station of the turntable assembly 4; when the heat dissipation pipes are conveyed to a certain length, the clamping cylinder 53 controls the gripper to clamp one end of the tape, and the feeding slide 52 drives the clamping cylinder 53 to drive the tape forward through the slide, and the tape feeding length is accurately ensured by the slide stroke of the feeding slide. When the tape reaches the preset position, the clamping cylinder 2 drives the pressure block to press down and fix the end of the tape; the guide cylinder 56 then starts, pushing the shearing assembly 57 to move in a straight line to the designated position, and the shearing blade quickly closes to cut the tape, and then resets. After the heat sink pipes are conveyed to a certain length, the lifting cylinder 541 drives the covering component 542 located below the tape to move upward. The covering component 542 pushes the tape upward, causing the tape to adhere to the heat sink pipes. Subsequently, the heat sink pipes enter the interior of the covering component 542. At this time, the heat sink pipes block the tape from moving upward, causing the tape to be in a U-shape, thereby achieving tape adhesion of multiple heat sink pipes. Then, the lifting cylinder 541 returns, the covering component 542 moves downward and detaches from the heat sink pipes, the bending mechanism 3 is activated, and the heat sink pipes covered with tape are bent. The turntable assembly 4 rotates synchronously. Then the tube feeding mechanism feeds the tube again, sending the next bending section to the bending mechanism. The coating mechanism first coats the tube with glue, and the turntable assembly 4 rotates in the opposite direction, driving the processed tube to rotate, and cooperating with the bending mechanism to perform a reverse bend; thus, the above process is repeated until the heat dissipation tube is formed.

[0035] Example 2: Based on Example 1, the following is added: The inner walls of the two sides of the pressure plate 542 are symmetrically equipped with buffer pads 543, and there is a spacing between the buffer pads 543 for placing the heat dissipation pipe. Thus, the pressure plate 542 is pressed vertically down under the drive of the lifting cylinder 541, so that the buffer pads 543 are in contact with the outer wall of the heat dissipation pipe, and the force is evenly applied to ensure that the tape tightly wraps the surface of the pipe, while avoiding deformation of the pipe or damage to the tape due to rigid contact. The spacing of the buffer pads 543 is adapted to heat dissipation pipes of different specifications, improving the versatility of the equipment.

[0036] Example 3: Based on Example 1, the following addition is made: the inner side of the gripper is provided with inwardly protruding teeth. The teeth maintain the gripping force of the gripper on the tape while reducing damage to the tape surface and preventing the tape edge from wrinkling or breaking. The teeth are staggered to enhance the gripping stability, adapt to the conveying needs of tapes of different thicknesses, and ensure the continuous and reliable coating process.

[0037] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
