Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic welding, and specifically relates to a force-sensing eccentric fine-tuning component for ultrasonic welding. Background Technology

[0002] In order to ensure the quality of welding, the ultrasonic bottom mold of the ultrasonic welding device needs to be kept in a horizontal position when welding workpieces.

[0003] However, it is difficult to achieve precision through manual adjustment. Therefore, there is an urgent need for a device that can automatically adjust and correct the level of the ultrasonic bottom mold. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide a force-sensing eccentricity fine-tuning component that can adjust and correct the levelness, thereby improving welding quality when applied to ultrasonic welding devices.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This utility model provides a force-sensing eccentricity fine-tuning component, comprising:

[0007] Force sensor;

[0008] Eccentric adjustment motor;

[0009] A speed reducer connected to the output end of the eccentric adjustment motor;

[0010] An eccentric wheel is connected to the output end of the reducer;

[0011] A roller mounting base, the upper end of which is connected to a force sensor, and the lower end of which has a rolling groove;

[0012] A roller is installed in the rolling groove and is arranged vertically opposite to the eccentric wheel, with the outer circumferential surface of the roller abutting against the outer circumferential surface of the eccentric wheel.

[0013] Furthermore, the outer circumference of the eccentric wheel is an elliptical structure, and the difference between the major and minor axes of the ellipse is 2.0 mm, which enables fine adjustment of the force sensor's height difference of 2.0 mm.

[0014] Furthermore, the center of the roller is connected to the roller mounting base via a bearing pin, allowing the roller to rotate relative to the roller mounting base.

[0015] Furthermore, it also includes a mounting base. The eccentric fine-tuning module also includes a transmission component, a mounting shaft, and a bearing. The mounting shaft is mounted on the mounting base. One end of the transmission component is connected to the output end of the reducer, and the other end is connected to the mounting shaft through the bearing. The eccentric wheel has a ring structure and is sleeved on the transmission component through the ring structure.

[0016] Furthermore, it also includes a sensor and a home-point sensing plate. The home-point sensing plate is mounted on the outer wall of the transmission component, and the sensor is fixed on the mounting base, corresponding to one end of the home-point sensing plate. When the eccentric fine-tuning module is working, the home-point sensing plate rotates together with the transmission component and the eccentric wheel. The sensor takes the starting point of the home-point sensing plate's rotation as the origin, measures the rotation angle of the home-point sensing plate, and then measures the rotation angle of the eccentric wheel. This allows for precise control of the roller's lifting height, achieving accurate adjustment of the levelness of the leveling plate.

[0017] The beneficial effects of this utility model are as follows: Compared with the prior art, this application, through the cooperation of a force sensor, an eccentric adjustment motor, a reducer, an eccentric wheel, and a roller mounting base, can control the eccentric wheel to perform eccentric movement based on force sensing, thereby assisting the ultrasonic bottom mold in achieving level adjustment. When applied to an ultrasonic welding device, it can improve the welding quality. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To achieve the above objectives, the technical solution of this utility model is as follows:

[0028] See Figure 1-7 As shown, this embodiment provides a horizontal correction mechanism, including:

[0029] Support plate 1;

[0030] Leveling adjustment plate 2;

[0031] Four sets of force-sensing eccentricity fine-tuning components 3 are arranged between the support base plate 1 and the level adjustment plate 2, and the four sets of force-sensing eccentricity fine-tuning components 3 are symmetrically arranged with respect to the center of the level adjustment plate 2.

[0032] The force-sensing eccentricity fine-tuning component 3 includes:

[0033] An eccentric fine-tuning module 31 is fixedly installed on the support base plate 1.

[0034] Force sensor 32, which is installed on the bottom surface of the leveling plate 2, is used to detect the force value of the leveling plate 2 that it bears;

[0035] The upper end of the roller 33 is connected to the force sensor 32, and the lower end abuts against the eccentric fine-tuning module 31.

[0036] The working principle of the leveling mechanism of this application is as follows: the force sensor 32 can detect the force value it bears on the leveling adjustment plate 2. When the force values ​​of the force sensors 32 of the four sets of force sensing eccentric fine-tuning components 3 are consistent, it indicates that the leveling adjustment plate 2 is in a horizontal state. When the force values ​​of the force sensors 32 of each set are inconsistent, the control system will set the same preset value for the force values ​​of each set of force sensors 32. Then, the preset value is used to control the action of each set of eccentric fine-tuning modules 31. The eccentric principle is used to control the roller 33 to rise and fall, thereby controlling the rise and fall of the force sensor 32, adjusting the force values ​​of each force sensor 32 so that the force values ​​of each force sensor 32 are consistent. When the force values ​​of each force sensor 32 are consistent, the leveling adjustment plate 2 will be adjusted to a horizontal state, thereby correcting the levelness of the leveling adjustment plate 2.

[0037] When the horizontal correction mechanism of this application is applied to an ultrasonic welding equipment, the support base plate 1 is installed on the frame, and the horizontality adjustment plate 2 is used to install the ultrasonic bottom mold. By adjusting the horizontality of the horizontality adjustment plate 2, the horizontality of the ultrasonic bottom mold can be precisely adjusted to ensure that the ultrasonic bottom mold is in a horizontal state and improve the quality of ultrasonic welding.

[0038] Furthermore, the eccentric fine-tuning module 31 includes an eccentric adjustment motor 311, a reducer 312, and an eccentric wheel 313. The reducer 312 is connected to the output end of the eccentric adjustment motor 311, and the eccentric wheel 313 is connected to the output end of the reducer 312. The roller 33 and the eccentric wheel 313 are arranged vertically opposite each other, and the outer circumferential surface of the roller 33 abuts against the outer circumferential surface of the eccentric wheel 313.

[0039] In this application, since the eccentric wheel 313 is located below the roller 33, it can support the roller 33. When the eccentric adjustment motor 311 drives the eccentric wheel 313 to rotate through the reducer 312, the eccentric wheel 313 can drive the roller 33 to rise and fall through eccentric motion.

[0040] Correspondingly, the force sensor 32 will also rise and fall synchronously. When the force sensor 32 rises, the force value it bears on the level adjustment plate 2 increases, and when it falls, the force value it bears on the level adjustment plate 2 decreases, thereby adjusting the force value of the force sensor 32. When the force value reaches the preset force value, the levelness of the level adjustment plate 2 can be adjusted and corrected.

[0041] Furthermore, the outer circumference of the eccentric wheel 313 is an elliptical structure, and the difference between the major and minor axes of the ellipse is 2.0 mm, which enables fine adjustment of the 2.0 mm height difference of the force sensor 32.

[0042] Furthermore, the force-sensing eccentric fine-tuning component 3 also includes a roller mounting base 34. The upper end of the roller mounting base 34 is connected to the force sensor 32, and the lower end of the roller mounting base 34 has a rolling groove 35. The roller 33 is disposed in the rolling groove 35, and the center of the roller 33 is connected to the roller mounting base 34 through a bearing pin 36, allowing the roller 33 to rotate relative to the roller mounting base 34. This structure allows the roller 33 to rotate within the rolling groove 35, facilitating its cooperation with the eccentric wheel 313 and preventing structural interference with the rotation of the eccentric wheel 313.

[0043] Furthermore, a mounting base 4 is provided on the supporting base plate 1. The eccentric fine-tuning module 31 also includes a transmission component 314, a mounting shaft 315, and a bearing 316. The mounting shaft 315 is mounted on the mounting base 4. One end of the transmission component 314 is connected to the output end of the reducer 312, and the other end is connected to the mounting shaft 315 via the bearing 316. The eccentric wheel 313 has a ring structure and is sleeved on the transmission component 314 via the ring structure. The above structure not only allows the eccentric adjustment module 31 to be mounted on the mounting base 4, but also allows the transmission component 314 to rotate relative to the mounting shaft 315 via the bearing 316, ensuring the smooth rotation of the eccentric wheel 313.

[0044] Furthermore, the eccentric fine-tuning module 31 also includes a sensor 317 and a home-point sensing plate 318. The home-point sensing plate 318 is mounted on the outer wall of the transmission component 314, and the sensor 317 is fixed on the mounting base 4 and corresponds to one end of the home-point sensing plate 318. When the eccentric fine-tuning module 31 is working, the home-point sensing plate 318 rotates together with the transmission component 314 and the eccentric wheel 313. The sensor 317 takes the starting point of the rotation of the home-point sensing plate 318 as the origin and measures the rotation angle of the home-point sensing plate 318 through the sensor 317, thereby measuring the rotation angle of the eccentric wheel 313. This allows for precise control of the lifting height of the roller 33, achieving precise adjustment of the levelness of the leveling plate 2.

[0045] Furthermore, the leveling plate 2 has a rectangular plate structure, and the four sets of force-sensing eccentric fine-tuning components 3 are respectively arranged below the four corners of the leveling plate 2. The supporting base plate 1 is also provided with stop blocks 5, the lower end of which is fixed to the supporting base plate 1. The upper inner side of the stop block 5 is provided with a limiting groove 6. There are four stop blocks 5, and the four corners of the leveling plate 2 are respectively supported on the bottom wall of the limiting groove 6 of the four stop blocks 5. The leveling plate 2 can move up and down within a small range on the limiting groove 6, allowing its levelness to be adjusted.

[0046] Furthermore, the stop block 5 includes a first stop block 51 and a second stop block 52. The lower ends of the first stop block 51 and the second stop block 52 are fixed on the support base plate 1. One side of the first stop block 51 is connected to the second stop block 52 to form an "L" shape. The limiting groove 6 is disposed on the inner side of the "L" shape.

[0047] Furthermore, the leveling mechanism also includes:

[0048] The connecting plate 7 is used to connect the ultrasonic bottom mold, and the connecting plate 7 is fixedly installed in the middle of the level adjustment plate 2;

[0049] The connecting seat 8 is used to connect the frame, and the connecting seat 8 is mounted on the support base plate 1;

[0050] Scrolling central axis 9;

[0051] The upper end of the rolling central shaft 9 is connected to the connecting plate 7, and the lower end is connected to the connecting seat 8.

[0052] Furthermore, a force-bearing shaft support plate 10 is installed at the bottom of the connecting disk 7. A spherical hole 101 is formed at the end of the force-bearing shaft support plate 10 away from the connecting disk 7. A spherical protrusion 91 is located at the upper end of the rolling central shaft 9, and the spherical protrusion 91 is disposed within the spherical hole 101. In this application, the rolling central shaft 9 serves as a central support shaft, supporting the middle of the leveling plate 2. When the force-sensing eccentric fine-tuning assembly 3 fine-tunes the height of the four corners of the leveling plate 2, the spherical protrusion 91 at the upper end of the rolling central shaft 9 can make slight corresponding movements within the spherical hole 101, allowing for smoother leveling adjustment of the leveling plate 2 without structural interference.

[0053] Furthermore, the horizontal correction mechanism also includes an outer cover 20, which wraps around the side of the force-sensing eccentricity fine-tuning component 3 and is fixed to the outer side of the stop block 5.

[0054] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
