Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic hot melting, and specifically to an ultrasonic hot melting method with uniform heating. Background Art

[0002] Ultrasonic waves are mainly used for the welding of metal materials. However, with the wide application of polymer materials, ultrasonic hot melting technology has gradually been applied to the connection of non-metal materials such as plastics. Early ultrasonic hot melting equipment was relatively simple, and the control of power and frequency was not precise enough, resulting in difficulty in ensuring heating uniformity. With the continuous development of electronic technology and materials science, ultrasonic hot melting equipment has made significant improvements in aspects such as power regulation, frequency stability, and transducer performance, providing a technical basis for realizing ultrasonic hot melting with uniform heating.

[0003] When clamping workpieces, when processing rod-shaped workpieces and rectangular workpieces, different fixtures need to be replaced for different types of workpieces, thus reducing the versatility and application range of the device, and increasing production costs and time costs. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: An ultrasonic hot melting method with uniform heating, including:

[0005] S1: Accurately place the two workpieces to be hot melted in the mold, ensure that their connection surfaces are closely fitted, and maintain good contact with the working surface of the ultrasonic mold;

[0006] S2: Start the ultrasonic hot melting device to make the mold generate high-frequency vibration. The ultrasonic energy is transmitted to the surface of the workpiece to be hot melted through the mold, causing the material molecules to vibrate and rub violently;

[0007] S3: Due to the propagation and action of ultrasonic energy inside the material, heat is generated simultaneously on the surface and inside of the material, achieving uniform heating. The generation of heat is mainly due to the frictional heat generation of material molecules under ultrasonic vibration. This heating method can make the material reach the melting point in a short time, and the temperature distribution is relatively uniform;

[0008] S4: When the material reaches the ideal hot melting state, stop the ultrasonic vibration;

[0009] S5: The hot melted part cools naturally in the mold to solidify the hot melted part. During the cooling process, keep the position of the part fixed to avoid being interfered by external forces to ensure the quality of the hot melt connection;

[0010] S6: After cooling and solidifying, take out the part and check the appearance of the hot melt connection part.

[0011] The ultrasonic hot melting device includes:

[0012] A main body, with an ultrasonic hot melt component fixedly connected to the top of the main body, and a collection component fixedly connected to the middle part inside the main body;

[0013] A clamping component, which is used to clamp and fix a material workpiece, and the bottom of the clamping component is fixedly connected to the middle part of the top of the main body;

[0014] The clamping component includes a base, the bottom of the base is fixedly connected to the middle part of the top of the main body, the top of the base is fixedly connected to a bottom plate, both sides of the top of the bottom plate are rotatably connected with a first lead screw, both sides of the bottom plate are fixedly connected with a motor, and the output end of the motor is fixedly connected to one end of the first lead screw. A limiting mechanism is slidably connected inside the bottom plate;

[0015] Place the workpiece on the bottom plate. By turning on the motor, the output end of the motor drives the first lead screw to rotate inside the bottom plate, so that the two limiting mechanisms move relative to each other, thereby clamping the workpiece placed on the bottom plate;

[0016] The limiting mechanism includes a clamping plate, the bottom of the clamping plate is fixedly connected with a slider, the side of the slider is slidably connected to the inside of the bottom plate, the inside of the slider is threadedly connected to the side of the first lead screw, the inside of the clamping plate is rotatably connected with a second lead screw, an arc plate is slidably connected inside the clamping plate, the inside of the arc plate is threadedly connected to the side of the second lead screw, the top of the clamping plate is rotatably connected with a limiting block, and the bottom of the limiting block is fixedly connected to the top of the second lead screw;

[0017] When clamping a rod-shaped workpiece, by rotating the limiting block on one clamping plate, the limiting block drives the second lead screw to rotate inside the clamping plate, thereby driving the arc plate to move upward. Similarly, reverse-rotate the limiting block on the other clamping plate, so that the arc plate on the other clamping plate moves downward, thereby appropriately adjusting the height of the two arc plates according to the rod workpiece with a diameter matching the arc plate;

[0018] Thus, the rod workpiece can be clamped. By turning on the motor, the output end of the motor drives the first lead screw to rotate inside the bottom plate, so that the two clamping plates move relative to each other on the bottom plate through the sliders, and the clamping plates drive the arc plates to clamp the rod-shaped workpiece;

[0019] When clamping a rectangular workpiece, adjust the arc plate to the highest position, so that the side of the clamping plate clamps the side of the rectangular workpiece;

[0020] Preferably, the collection component includes a collection housing, the side of the collection housing is fixedly connected to the inner side of the main body, a net plate is fixedly connected to the top of the collection housing, a filtering mechanism is fixedly connected to the inner side of the collection housing, a net rack is fixedly connected to the inner side of the collection housing, the net rack is arranged below the net plate, a discharge mechanism is fixedly connected to the side of the collection housing, a blocking mechanism is fixedly connected to the inner side of the collection housing, the blocking mechanism is arranged below the net rack, and a cleaning mechanism is slidably connected to the bottom of the blocking mechanism;

[0021] Ultrasonic hot melting uses the energy of ultrasonic waves to generate heat by the friction of surface molecules of an object, thereby realizing the connection of materials. In this process, the material to be processed is in a high-temperature state, and some substances on its surface will undergo physical changes and be released in gaseous form to form waste gas. When performing hot melting work, by turning on the filtering mechanism, the suction generated during the operation of the filtering mechanism is used to draw the waste gas generated during hot melting work into the collection housing;

[0022] When collecting waste gas, the dust and impurities on the main body will enter the collection housing together with the waste gas. At the same time, after the hot melting work is completed, when cleaning the workbench, the impurities swept can be directly swept into the collection housing;

[0023] The impurities that enter the collection housing following the suction generated by the filtering mechanism are collected by falling on the net rack. At the same time, by arranging a blocking mechanism inside the collection housing, the flocculent dust entering the collection housing can be grabbed, and the cleaning mechanism can clean the blocking mechanism;

[0024] Preferably, the discharge mechanism includes a discharge housing, the side of the discharge housing is fixedly connected to the inner side of the collection housing, a collection cylinder is fixedly connected to the bottom of the discharge housing, an electric hydraulic cylinder is fixedly connected to the side of the discharge housing away from the collection housing, the output end of the electric hydraulic cylinder is fixedly connected to a connecting shaft, and the other end of the connecting shaft is fixedly connected to a discharge rack, and the bottom of the discharge rack is in contact with the top of the net rack;

[0025] When a large amount of impurities accumulate on the net rack, by turning on the electric hydraulic cylinder, the output end of the electric hydraulic cylinder drives the discharge rack to move towards the discharge housing on the net rack through the connecting shaft, so that the discharge rack pushes the impurities accumulated on the net rack off the net rack, and the impurities fall into the collection cylinder for collection, thereby preventing a large amount of impurities from accumulating on the net rack and causing the normal ventilation work of the net rack;

[0026] Preferably, the blocking mechanism includes a connecting plate and a rotating shaft. The connecting plate is fixedly connected to the inner side of the collection housing. Both the upper and lower sides of the rotating shaft are fixedly connected with rotating frames. The bottom of the lower rotating frame is rotatably connected to the top of the connecting plate. Rotating grooves are formed on both sides of the rotating frame, and a grasping rod is rotatably connected to the inner side of the rotating groove. Grasping grooves are formed on both sides of the grasping rod;

[0027] When the filtering mechanism sucks air inside the collection housing, a driving motor is arranged at the bottom of the connecting plate, and the output end of the driving motor is fixedly connected to the bottom of the rotating frame. Thus, when the filtering mechanism works, the rotating frame is driven to rotate by the output end of the driving motor, so that the rotating frame drives the grasping rod to rotate in the rotating groove. At the same time, grasping grooves are formed on both sides of the grasping rod, so as to grasp the flocculent dust that follows the waste gas into the collection housing from the outside;

[0028] Preferably, the cleaning mechanism includes a cleaning frame. Connecting rods are fixedly connected to the top of the cleaning frame. The top of the connecting rods is slidably connected to the bottom of the connecting plate. A connecting spring is sleeved on the connecting rods. The top of the connecting spring is fixedly connected to the bottom of the connecting plate, and the bottom of the connecting spring is fixedly connected to the top of the cleaning frame. Yielding grooves are evenly formed on the side of the cleaning frame. A cleaning rod is fixedly connected to the top of the cleaning frame, and the cleaning rod is concentric with the circular hole on the connecting plate;

[0029] When the suction machine works, the suction force generated causes air to be pumped out inside the connecting pipe, so that the gas passes through the through holes and enters the connecting pipe. Thus, driven by the suction force generated by the suction machine, the cleaning frame moves downward, so that the cleaning frame pulls the connecting spring downward through the connecting rod. At the same time, the cleaning rod is driven to disengage from the circular hole on the connecting plate. When the waste gas filtering work is over, by turning off the filtering mechanism, the cleaning frame moves upward under the pulling force of the connecting spring, so that the cleaning rod dredges the circular hole on the connecting plate, preventing impurities and debris from blocking at the circular hole of the connecting plate and interfering with the normal ventilation effect of the connecting plate;

[0030] Preferably, the filtering mechanism includes a filtering housing. The side of the filtering housing is fixedly connected to the inner side of the collection housing and the inner side of the main body. Filter meshes are fixedly connected to both ends of the filtering housing. An activated carbon box is fixedly connected to the inner side of the filtering housing near the end close to the collection housing. An air suction machine is fixedly connected to the inner side of the filtering housing near the activated carbon box. A connecting pipe is fixedly connected to the end of the filtering housing close to the collection housing. The other end of the connecting pipe is fixedly connected to the inner wall of the collection housing. Through holes are evenly formed on the side of the connecting pipe;

[0031] By turning on the suction machine, the suction force generated by the suction machine is used to draw the waste gas generated during the hot melting operation into the collection housing. Through continuous suction work by the suction machine, the waste gas passes through the filter screen and enters the activated carbon box, thereby filtering and treating the waste gas. The filtered and purified waste gas is discharged from the collection housing by the suction machine.

[0032] The present invention provides an ultrasonic hot melting method with uniform heating. It has the following beneficial effects:

[0033] 1. For the ultrasonic hot melting method with uniform heating, a clamping component is provided. This device can not only clamp the rod-shaped workpiece with a diameter matching the arc plate by adjusting the height of the arc plate, but also adjust the arc plate to the highest position and clamp the rectangular workpiece with the side of the clamping plate, realizing the clamping of workpieces with various shapes, improving the versatility and application range of the device, reducing the trouble of replacing different fixtures for different types of workpieces, and lowering the production cost and time cost.

[0034] 2. For the ultrasonic hot melting method with uniform heating, a limiting mechanism is provided. Whether clamping the rod-shaped workpiece by fitting with the arc plate or clamping the rectangular workpiece with the side of the clamping plate, it can ensure that the workpiece remains stable during the processing, reducing shaking and displacement, which is beneficial to improving the processing accuracy and product quality.

[0035] 3. For the ultrasonic hot melting method with uniform heating, a blocking mechanism is provided. By driving the motor to drive the rotating frame and the grasping rod to rotate, and using the grasping grooves on both sides of the grasping rod, it can effectively grasp the flocculent dust that enters the collection housing along with the waste gas, preventing it from accumulating in the collection housing or being discharged with the purified waste gas, and improving the purification effect of the waste gas.

[0036] 4. For the ultrasonic hot melting method with uniform heating, a cleaning mechanism is provided. The blockage of the round holes will cause poor air flow, affect the distribution of the waste gas in the collection housing, and reduce the filtration efficiency. The cleaning rod dredges the round holes, optimizing the air flow distribution, enabling the waste gas to pass through the filtration mechanism more evenly, making full contact with the filter media such as the filter screen and activated carbon, thereby enhancing the filtration effect and improving the quality of the purified gas.

[0054] S4: When the material reaches the ideal hot-melt state, stop the ultrasonic vibration;

[0055] S5: The hot-melted part cools naturally in the mold to solidify the hot-melted part. During the cooling process, keep the position of the part fixed to avoid being interfered by external forces to ensure the quality of the hot-melt connection;

[0057] Please refer to Figures 1 - 3 , the present invention provides a technical solution: The ultrasonic hot-melting device includes:

[0058] The main body 1, the top of the main body 1 is fixedly connected with an ultrasonic hot-melting component 2, and the middle part inside the main body 1 is fixedly connected with a collecting component 4;

[0059] The clamping component 3, which is used to clamp and fix the material workpiece, and the bottom of the clamping component 3 is fixedly connected with the middle part of the top of the main body 1;

[0060] Please refer to Figures 1 - 4 , the clamping component 3 includes a base 31, the bottom of the base 31 is fixedly connected with the middle part of the top of the main body 1, the top of the base 31 is fixedly connected with a bottom plate 32, both sides of the top of the bottom plate 32 are rotatably connected with a first lead screw 33, both sides of the bottom plate 32 are fixedly connected with a motor 34, the output end of the motor 34 is fixedly connected with one end of the first lead screw 33, and a limiting mechanism 35 is slidably connected inside the bottom plate 32;

[0061] Place the workpiece on the bottom plate 32, by turning on the motor 34, drive the first lead screw 33 to rotate inside the bottom plate 32 through the output end of the motor 34, so that the two limiting mechanisms 35 move relatively, thereby clamping the workpiece placed on the bottom plate 32;

[0062] Please refer to Figures 1 - 5 , the limiting mechanism 35 includes a clamping plate 351. A slider 352 is fixedly connected to the bottom of the clamping plate 351. The side of the slider 352 is slidably connected to the inner side of the bottom plate 32. The inner side of the slider 352 is threadedly connected to the side of the first lead screw 33. A second lead screw 353 is rotatably connected to the inner side of the clamping plate 351. An arc plate 354 is slidably connected to the inner side of the clamping plate 351. The inner side of the arc plate 354 is threadedly connected to the side of the second lead screw 353. A limiting block 355 is rotatably connected to the top of the clamping plate 351. The bottom of the limiting block 355 is fixedly connected to the top of the second lead screw 353. The number of clamping plates 351 is four. The arc surfaces of the arc plates 354 on two symmetrically arranged clamping plates 351 are arranged in opposite directions. One arc plate 354 is arranged upward, and the other arc plate 354 is arranged downward;

[0063] When clamping a rod-shaped workpiece is required, by rotating the limiting block 355 on one clamping plate 351, the second lead screw 353 is driven by the limiting block 355 to rotate inside the clamping plate 351, thereby driving the arc plate 354 to move upward. Similarly, the limiting block 355 on the other clamping plate 351 is rotated in the reverse direction, so that the arc plate 354 on the other clamping plate 351 moves downward, thereby appropriately adjusting the height of the two arc plates 354 according to the rod workpiece that fits the diameter of the arc plate 354;

[0064] Thereby, the rod workpiece can be clamped. By starting the motor 34, the output end of the motor 34 drives the first lead screw 33 to rotate inside the bottom plate 32, so that the two clamping plates 351 move relative to each other on the bottom plate 32 through the sliders 352, and the clamping plates 351 drive the arc plates 354 to clamp the rod-shaped workpiece;

[0065] When clamping a rectangular workpiece, by adjusting the arc plate 354 to the highest position, the side of the clamping plate 351 clamps the side of the rectangular workpiece;

[0066] Whether the rod-shaped workpiece is clamped by fitting with the arc plate 354 or the rectangular workpiece is clamped by the side of the clamping plate 351, it can ensure that the workpiece remains stable during the processing, reduce shaking and displacement, and is beneficial to improving the processing accuracy and product quality;

[0067] Please refer to Figures 1 - 7, the present invention provides a technical solution: The collection component 4 includes a collection housing 41, the side of the collection housing 41 is fixedly connected to the inner side of the main body 1, a mesh plate 43 is fixedly connected to the top of the collection housing 41, a filtering mechanism 42 is fixedly connected to the inner side of the collection housing 41, a grid 44 is fixedly connected to the inner side of the collection housing 41, the grid 44 is arranged below the mesh plate 43, a discharge mechanism 45 is fixedly connected to the side of the collection housing 41, a blocking mechanism 46 is fixedly connected to the inner side of the collection housing 41, the blocking mechanism 46 is arranged below the grid 44, and a cleaning mechanism 47 is slidably connected to the bottom of the blocking mechanism 46;

[0068] Ultrasonic hot melting uses the energy of ultrasonic waves to cause the surface molecules of an object to generate heat by friction, thereby realizing the connection of materials. In this process, the processed material is in a high-temperature state, and some substances on its surface will undergo physical changes and be released in gaseous form to form waste gas. When performing hot melting work, by turning on the filtering mechanism 42, the suction force generated during the operation of the filtering mechanism 42 is used to suck the waste gas generated during the hot melting work into the collection housing 41;

[0069] When collecting waste gas, the dust and impurities on the main body 1 will enter the collection housing 41 together with the waste gas. At the same time, after the hot melting work is completed, when cleaning the workbench, the impurities swept can be directly swept into the collection housing 41;

[0070] The impurities that enter the collection housing 41 following the suction force generated by the filtering mechanism 42 are collected by falling on the grid 44. At the same time, by arranging a blocking mechanism 46 inside the collection housing 41, the flocculent dust entering the collection housing 41 can be grabbed, and the cleaning mechanism 47 can clean the blocking mechanism 46;

[0071] Please refer to Figures 1 - 8 , the discharge mechanism 45 includes a discharge housing 451, the side of the discharge housing 451 is fixedly connected to the inner side of the collection housing 41, a collection cylinder 452 is fixedly connected to the bottom of the discharge housing 451, an electric hydraulic cylinder 453 is fixedly connected to the side of the discharge housing 451 away from the collection housing 41, a connecting shaft 454 is fixedly connected to the output end of the electric hydraulic cylinder 453, the other end of the connecting shaft 454 is fixedly connected to a discharge frame 455, and the bottom of the discharge frame 455 is in contact with the top of the grid 44;

[0072] When a large amount of impurities accumulate on the grid 44, by turning on the electric hydraulic cylinder 453, the output end of the electric hydraulic cylinder 453 drives the discharge frame 455 to move on the grid 44 towards the discharge housing 451 through the connecting shaft 454. As a result, the discharge frame 455 pushes the impurities accumulated on the grid 44 out of the grid 44, causing the impurities to fall into the collection cylinder 452 for collection, thereby preventing a large amount of impurities from accumulating on the grid 44 and causing the normal ventilation work of the grid 44;

[0073] Please refer to Figures 1 - 9 , the blocking mechanism 46 includes a connecting plate 461 and a rotating shaft 463. The connecting plate 461 is fixedly connected to the inner side of the collection housing 41. Rotating frames 462 are fixedly connected to both the upper and lower sides of the rotating shaft 463. The bottom of the lower rotating frame 462 is rotatably connected to the top of the connecting plate 461. Rotating grooves 464 are formed on both sides of the rotating frame 462. A grasping rod 465 is rotatably connected to the inner side of the rotating groove 464. Grasping grooves 466 are formed on both sides of the grasping rod 465;

[0074] When the filtering mechanism 42 sucks air inside the collection housing 41, a driving motor is provided at the bottom of the connecting plate 461, and the output end of the driving motor is fixedly connected to the bottom of the rotating frame 462. Thus, when the filtering mechanism 42 is working, the output end of the driving motor drives the rotating frame 462 to rotate, causing the rotating frame 462 to drive the grasping rod 465 to rotate in the rotating groove 464. At the same time, by forming grasping grooves 466 on both sides of the grasping rod 465, the flocculent dust that follows the exhaust gas into the collection housing 41 from the outside is grasped;

[0075] Please refer to Figures 1 - 10 , the cleaning mechanism 47 includes a cleaning frame 471. Connecting rods 473 are fixedly connected to the top of the cleaning frame 471. The top of the connecting rods 473 is slidably connected to the bottom of the connecting plate 461. A connecting spring 474 is sleeved on the connecting rods 473. The top of the connecting spring 474 is fixedly connected to the bottom of the connecting plate 461, and the bottom of the connecting spring 474 is fixedly connected to the top of the cleaning frame 471. Yielding grooves 472 are evenly formed on the side of the cleaning frame 471. A cleaning rod 475 is fixedly connected to the top of the cleaning frame 471, and the cleaning rod 475 is concentric with the circular hole on the connecting plate 461;

[0076] When the suction machine 423 works, the suction force generated causes the inside of the connecting pipe 425 to be evacuated, so that gas enters the connecting pipe 425 through the through holes 426. Then, driven by the suction force generated by the suction machine 423, the cleaning frame 471 moves downward. Thus, the cleaning frame 471 pulls the connecting spring 474 downward through the connecting rod 473, and at the same time drives the cleaning rod 475 to disengage from the round hole on the connecting plate 461. Also, when the waste gas filtration work is over, by closing the filtration mechanism 42, the cleaning frame 471 is pulled by the tension of the connecting spring 474, so that the cleaning frame 471 drives the cleaning rod 475 to move upward, thereby enabling the cleaning rod 475 to dredge the round hole on the connecting plate 461, preventing impurities and debris from blocking at the round hole of the connecting plate 461, and thus interfering with the normal ventilation effect of the connecting plate 461;

[0077] Please refer to Figures 1 - 11 , the filtration mechanism 42 includes a filtration housing 421. The side of the filtration housing 421 is fixedly connected to the inner side of the collection housing 41 and the inner side of the main body 1. Both ends of the filtration housing 421 are fixedly connected with filter meshes 422. The inner side of the filtration housing 421 near one end of the collection housing 41 is fixedly connected with an activated carbon box 424. On the inner side of the filtration housing 421 near the activated carbon box 424, a suction machine 423 is fixedly connected. One end of the filtration housing 421 near the collection housing 41 is fixedly connected with a connecting pipe 425. The other end of the connecting pipe 425 is fixedly connected to the inner wall of the collection housing 41. The side of the connecting pipe 425 is evenly provided with through holes 426;

[0078] By turning on the suction machine 423, the suction force generated by the suction machine 423 causes the waste gas generated during the hot melting process to enter the collection housing 41. By continuously performing the suction work with the suction machine 423, the waste gas enters the activated carbon box 424 through the filter mesh 422, thereby performing the filtration treatment work on the waste gas. Then, the suction machine 423 discharges the filtered and purified waste gas out of the collection housing 41.

[0079] Specific working process:

[0080] Place the workpiece to be hot melted on the clamping component 3 of the equipment workbench to ensure the accurate position of the workpiece and guarantee the position accuracy of each hot melting;

[0081] According to the material, shape, size and hot melting requirements of the workpiece, adjust the ultrasonic frequency, power, welding time, and pressure holding time parameters of the ultrasonic hot melting component 2;

[0082] The equipment starts to work, and the ultrasonic hot melting component 2 generates a high-frequency electrical signal, which is transmitted to the transducer;

[0083] The transducer converts high-frequency electrical signals into mechanical vibrations, and amplifies and transmits the vibration amplitude to the clamping die through a horn;

[0084] The clamping die transfers the vibration energy to the workpiece, causing the molecules on the surface of the workpiece to undergo intense friction and vibration, thereby generating heat. Under the action of the heat, the connecting part of the workpiece gradually heats up to the melting point, begins to soften and fuse;

[0085] When the hot melt effect meets the requirements, the ultrasonic hot melt component 2 stops outputting electrical signals, the transducer stops vibrating, and the ultrasonic action ends;

[0086] The workpiece cools naturally in the clamping die. During the cooling process, the material at the hot melt part gradually solidifies and takes shape, forming a firm connection;

[0087] After cooling is completed, loosen the positioning fixture and take out the hot-melted workpiece.

[0088] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments in the present invention, other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
