Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding, specifically to an ultrasonic welding machine with a conveyor belt. Background Technology

[0002] Ultrasonic welding is a highly efficient and environmentally friendly solid-state welding technology that uses high-frequency vibration energy to join materials. Its core principle is to use the frictional heat generated by mechanical vibration to locally melt or plastically deform the contact surface, thereby achieving a strong bond.

[0003] Currently, ultrasonic welding typically requires workers to place the workpiece under the welding head, posing certain safety risks and resulting in low efficiency. Therefore, some ultrasonic welding machines with conveyor belts have been introduced to the market. However, these conveyor belts are fixed in position and can only be used for one type of workpiece, limiting their application range and making them unsuitable for widespread use. Utility Model Content

[0004] The purpose of this invention is to provide an ultrasonic welding machine with a conveyor belt to solve the problems of low working efficiency and limited application range of existing ultrasonic welding machines.

[0005] To achieve the above objectives, this utility model provides an ultrasonic welding machine with a conveyor belt, including a welding module and a frame. The welding module is mounted on the frame and includes a welding head. The frame includes a work platform, and the welding module is mounted on the work platform. The work platform also includes a conveyor module, which includes a conveyor belt extending along a first direction. The conveyor belt is racetrack-shaped and has several workpiece placement plates. The welding head can move to a second direction on at least one workpiece placement plate. The conveyor module also includes a baffle and a first mounting block. The conveyor belt is located inside the baffle, and at least one first mounting block is located on the outer periphery of the baffle. The conveyor module is fixed to the work platform by the first mounting block. The work platform has a first fixing hole, and the first mounting block has a first movable hole. The length of the first movable hole in the first direction is greater than the length of the first fixing hole in the first direction. The length of the first fixing hole in a third direction matches the length of the first movable hole in the third direction. The frame and the conveyor module are fixed by screws to the first fixing hole and the first movable hole. The first direction, the second direction, and the third direction are all perpendicular to each other.

[0006] As can be seen from the above scheme, the ultrasonic welding machine of this utility model includes a conveyor belt with several workpiece placement plates on it. The workpiece placement plates are used to place workpieces. The conveyor belt is a racetrack-shaped conveyor belt that can circulate along a first direction. The operator only needs to stand on one side of the conveyor belt and place the workpiece on the workpiece placement plate. The workpiece will move with the conveyor belt until it corresponds directly to the welding head, resulting in higher safety and improved work efficiency. Furthermore, the conveyor module is fixed to the work platform by a first mounting block. The area of ​​the first movable hole is larger than the first fixed hole, allowing the fixed position of the conveyor belt on the work platform to be adjusted and changed. Specifically, the fixed position in the first direction can be changed. Therefore, when the conveyor module transports workpieces of different sizes, the fixed position of the conveyor module can be adjusted to ensure that the workpiece to be welded is directly aligned with the welding head, guaranteeing the welding effect. This allows the ultrasonic welding machine to be applied to workpieces of different sizes, broadening its application range and increasing its practicality.

[0007] A further proposed solution is to make the first fixing hole a circular through hole and the first movable hole a long strip through hole.

[0008] As can be seen from the above scheme, the first fixed hole adopts a circular through hole while the first movable hole adopts an elongated through hole design. The circular through hole serves as a fixed reference, and its geometric symmetry ensures the concentricity when the screw is inserted, creating a stable constraint between the conveying module and the working platform in the third direction, effectively resisting the risk of displacement caused by welding vibration. The long axis of the elongated through hole extends along the first direction, and its short axis matches the diameter of the circular through hole. This structure gives the conveying module a degree of freedom for fine adjustment in the first direction. When it is necessary to adapt to workpieces of different sizes or adjust the welding position, it is only necessary to loosen the screw and slide the conveying module along the long axis of the elongated through hole to achieve precise displacement without disassembling or repositioning the entire structure. At the same time, the dimensional consistency of the elongated through hole and the circular through hole in the third direction ensures a tight fit between the two in the vertical direction after the screw is tightened, avoiding assembly gaps caused by differences in hole shape.

[0009] A further embodiment includes a drive unit, a first gear, a second gear, a drive belt, and two connecting shafts. The two connecting shafts are respectively connected and fixed to the conveyor belt. One of the connecting shafts is coaxially connected to the second gear. The drive unit is connected to the first gear, and the drive unit drives the first gear to rotate. The first gear and the second gear are connected through the drive belt.

[0010] As can be seen from the above scheme, the drive unit is a motor. The motor drives the first gear to rotate, which in turn drives the second gear to rotate through the drive belt, thereby causing the connecting shaft to drive the conveyor belt to rotate. The structure is simple and has a long service life.

[0011] A further design involves placing a photoelectric sensor on the side of the second gear furthest from the conveyor belt. The photoelectric sensor is coaxially mounted with the second gear. A sensor is mounted on one side of the second gear and fixed to a baffle plate. The photoelectric sensor can rotate through the sensor.

[0012] As can be seen from the above scheme, by setting up photoelectric sensors and photoelectric sensors, the number of rotations of the connecting shaft can be clearly known, thereby controlling the conveyor belt's transmission distance and facilitating monitoring.

[0013] A further embodiment is that one end of another connecting shaft not connected to the second gear is connected to a second mounting block. The second mounting block is provided with a second movable hole, and the baffle is provided with a second fixed hole. The length of the second movable hole in the first direction is greater than the length of the second fixed hole in the first direction, and the length of the second fixed hole in the second direction matches the length of the second movable hole in the second direction. The conveyor belt is fixed to the baffle by connecting the second fixed hole and the second movable hole with screws.

[0014] A further proposed solution is to make the second fixing hole a circular through hole and the second movable hole a long strip through hole.

[0015] As can be seen from the above scheme, the above arrangement allows the tension of the conveyor belt to be adjusted to accommodate the welding of different workpieces.

[0016] A further option is to provide an auxiliary fixing block on one side of the second mounting block. The auxiliary fixing block is fixed to the baffle, and the auxiliary fixing block is connected to the second mounting block by a connecting rod.

[0017] As can be seen from the above scheme, the setting of auxiliary fixing blocks further improves the stability of the connection between the conveyor belt and the baffle.

[0018] A further solution is that the ultrasonic welding machine is equipped with a welding position, the welding head can be moved to the welding position, a pressure plate is set at the welding position, the pressure plate is fixedly connected to the baffle, the second direction is the vertical direction, and the pressure plate is located in the middle between the upper and lower conveyor belts of the racetrack-shaped conveyor belt.

[0019] As can be seen from the above scheme, the pressure plate provides support force when the welding head is welded downwards, ensuring the stability of the welding.

[0020] A further option is to install at least one drive cylinder on the baffle at the welding position. The drive cylinder is connected to a pressure block, which can move up and down under the drive of the drive cylinder, and the pressure block is always located above the conveyor belt.

[0021] As can be seen from the above scheme, the pressure block presses the workpiece placement position to fit with the pressure plate, ensuring the accuracy of welding head welding.

[0022] A further solution is to install a protective cover at the welding position, located above the conveyor belt, so that the welding head can extend into the protective cover.

[0023] As can be seen from the above scheme, the protective cover plays a protective role and avoids the safety hazards caused by welding.

[0024] A further design is to include a discharge port on the frame, located on one side of the work platform, close to the conveyor belt.

[0025] As can be seen from the above scheme, the discharge port can receive the material bucket externally. The workpieces that have been welded continue to be transported to the discharge port by the conveyor belt. During the conveyor belt transport process, they fall out of the discharge port to complete the material collection. The structure is simple and the efficiency is high. Attached Figure Description

[0035] See Figure 1 and Figure 8 The ultrasonic welding machine with conveyor belt provided in this embodiment includes a welding module 3, a frame 1, and a conveyor module 2, with the welding module 3 and the conveyor module 2 mounted on the frame 1. The welding module 3 includes a welding head 31.

[0036] The frame 1 includes a working platform 11, wheels 12, and a receiving cavity 13. The working platform 11 has a first fixing hole 111, a welding module fixing hole 112, and a discharge port 113. The first fixing hole 111 is used to install and fix the conveying module 2 onto the working platform 11, and the welding module fixing hole 112 is used to install and fix the welding module 3 onto the working platform 11. The discharge port 113 is located on one side of the edge of the working platform 11. The receiving cavity 13 is located below the working platform 11, and it houses the control structure for operating the welding module 3 and the structure for connecting to an external power source. Several wheels 12 are provided at the bottom of the frame 1 to facilitate the movement of the ultrasonic welding machine.

[0037] The welding module 3 includes a welding head 31, a mounting base 33, and a placement cavity 34. The mounting base 33 is mounted on the work platform 11, and the placement cavity 34 is disposed on the mounting base 33. The welding head 31 is connected to the placement cavity 34, and the welding head 31 faces the conveying module 2. A drive motor (not shown in the figure) is disposed in the placement cavity 34 to drive the welding head 31 to move closer to or away from the conveying module 2.

[0038] The conveying module 2 includes a conveyor belt 23 extending along a first direction, a baffle 21, and a first mounting block 22. The baffle 21 includes a first baffle 211 extending along the first direction and a second baffle 212 extending along a third direction, and the two first baffles 211 and the two second baffles 212 are joined together to form the baffle 21. The first direction, the second direction, and the third direction are perpendicular to each other.

[0039] The conveyor belt 23 is disposed within the baffle 21, and at least one first mounting block 22 is disposed on the outer periphery of the baffle 21. The conveying module 2 is fixed to the working platform 11 through the first mounting block 22. The first mounting block 22 is provided with a first movable hole 221. The length of the first movable hole 221 in the first direction is greater than the length of the first fixed hole 111 in the first direction. The length of the first fixed hole 111 in the third direction matches the length of the first movable hole 221 in the third direction. The frame 1 and the conveying module 2 are fixed by screws to the first fixed hole 111 and the first movable hole 221. In this embodiment, the first fixed hole 111 is a circular through hole, and the first movable hole 221 is an elongated through hole. The first fixed hole 111 adopts a circular through hole design, while the first movable hole 221 adopts an elongated through hole design. The circular through hole serves as a fixed reference, and its geometric symmetry ensures the concentricity when the screw is inserted, creating a stable constraint between the conveying module 2 and the working platform 11 in the third direction, effectively resisting the risk of displacement caused by welding vibration. The long axis of the elongated through hole extends along the first direction, and its short axis matches the diameter of the circular through hole. This structure gives the conveying module a degree of freedom for fine adjustment in the first direction. When it is necessary to adapt to workpieces of different sizes or adjust the welding position, it is only necessary to loosen the screw and slide the conveying module along the long axis of the elongated through hole to achieve precise displacement without disassembling or repositioning the entire structure. At the same time, the dimensional consistency of the elongated through hole and the circular through hole in the third direction ensures a tight fit between the two in the vertical direction after the screw is tightened, avoiding assembly gaps caused by differences in hole shape.

[0040] The conveyor belt 23 is a racetrack-shaped conveyor belt, with the discharge port 113 located near the downstream side of the conveyor belt 23. Several workpiece placement plates 24 are evenly distributed on the conveyor belt 23. In this embodiment, the welding head 31 is located on the second direction of the conveyor belt 23 (the second direction is vertical), directly above the conveyor belt 23. The welding head 31 can move up and down to move closer to or away from the conveyor module 2. The conveyor module 2 also includes a drive unit 231, a first gear 232, a second gear 233, a drive belt 234, and two connecting shafts 237. The two connecting shafts 237 are respectively connected and fixed to the conveyor belt 23, forming a racetrack-shaped conveyor belt with an upper and lower conveyor belt. One of the connecting shafts 237 is coaxially connected to the second gear 233. The drive unit 231 is connected to the first gear 232, driving the first gear 232 to rotate. The first gear 232 and the second gear 233 are connected via the drive belt 234. In this embodiment, the drive unit 231 is a motor. The motor drives the first gear 232 to rotate, which in turn drives the second gear 233 to rotate via the drive belt 234, thereby causing the connecting shaft 237 to rotate the conveyor belt 23. A photoelectric sensor 236 is provided on the side of the second gear 233 away from the conveyor belt 23. The photoelectric sensor 236 is coaxially arranged with the second gear 233. A sensor 235 is provided on one side of the second gear 233 and is fixed to the baffle 21. The photoelectric sensor 236 can rotate through the sensor 235. By setting the photoelectric sensor 236 and the sensor 235, the number of rotations of the connecting shaft 237 can be clearly determined, thereby controlling the conveying distance of the conveyor belt 23 and facilitating monitoring.

[0041] One end of another connecting shaft 237, which is not connected to the second gear 233, is connected to a second mounting block 238. The second mounting block 238 has a second movable hole 2381, and the baffle 21 has a second fixed hole. The length of the second movable hole 2381 in its first direction is greater than the length of the second fixed hole in its first direction, and the length of the second fixed hole in its second direction matches the length of the second movable hole 2381 in its second direction. The conveyor belt 23 is fixed to the baffle 21 by screws connecting the second fixed hole and the second movable hole 2381. In this embodiment, the second fixed hole is a circular through hole, and the second movable hole 2381 is an elongated through hole.

[0042] Furthermore, an auxiliary fixing block 239 is provided on one side of the second mounting block 238. The auxiliary fixing block 239 is fixed on the baffle 21, and the auxiliary fixing block 239 is connected to the second mounting block 238 by a connecting rod 230.

[0043] The ultrasonic welding machine is equipped with a welding position. In this embodiment, the welding head 31 is positioned above the welding position and can move downwards to the welding position. A pressure plate 25 is provided at the welding position, and the pressure plate 25 is fixedly connected to the baffle 21. The pressure plate 25 is located between the upper and lower conveyor belts of the racetrack-shaped conveyor belt 23. The pressure plate 25 is fixedly connected to two first baffles 211. Support bars 26 are provided on the portions of the two first baffles 211 that are not connected to the pressure plate 25. The support bars 26 are respectively located on the side of the two first baffles 211 facing the conveyor belt 23. Each support bar 26 on the side facing the pressure plate 25 and each end of the pressure plate 25 facing each support bar 26 are provided with rounded corners to facilitate the transport of the workpiece placement plate 24 fixed on the conveyor belt 23.

[0044] At least one drive cylinder 251 is provided on the baffle 21 at the welding position. In this embodiment, there are two drive cylinders 251, which are respectively set on the two first baffles 211 and are arranged opposite to each other. Each drive cylinder 251 is connected to a pressure block 252. The pressure block 252 can move up and down under the drive of the drive cylinder 251. The pressure block 252 is always located above the conveyor belt 23, thereby realizing the relaxation and pressing of the workpiece placement plate 24. The pressure block 252 presses the workpiece placement position 24 into contact with the pressure plate 25 to ensure the accuracy of welding head welding.

[0045] A protective cover 32 is provided at the welding position. The protective cover 32 is located above the conveyor belt 23, and the cross-section of the protective cover 32 is not smaller than the cross-section of the workpiece placement plate 24. The welding head 31 can extend into the protective cover 23 to perform welding. The protective cover 32 is provided with several notches 321, which are used to allow the workpiece placement plate 24 to pass through and the pressure block 252 to move.

[0046] A control panel 27 is also provided on one side of the baffle 21. The control panel 27 is electrically connected to the control system, which is used to control the working status of the conveying module 2 and the welding module 3.

[0047] The ultrasonic welding machine of this embodiment includes a conveyor belt 23 with several workpiece placement plates 24. The workpiece placement plates 24 are used to place workpieces. The conveyor belt 23 is a racetrack-shaped conveyor belt that can circulate and transport workpieces in a first direction. The operator only needs to be on one side of the upstream of the conveyor belt 23 and place the workpiece on the workpiece placement plate 24. The workpiece will move with the conveyor belt until it corresponds to the welding head 31, thereby performing welding. During welding, a protective cover 32 is provided on the outside for protection, which improves safety and work efficiency. The discharge port 113 can receive a material bucket. After welding, the workpiece continues to be transported to the discharge port 113 via the conveyor belt 23. During the conveying process of the conveyor belt 23, the workpiece falls out of the discharge port 113, completing the material collection. The structure is simple and highly efficient.

[0048] Furthermore, the conveying module 2 is fixed to the working platform 11 via the first mounting block 22. The area of ​​the first movable hole 221 is larger than that of the first fixed hole 111, which allows the fixed position of the conveyor belt 23 on the working platform 11 to be adjusted and changed. Specifically, the fixed position in the first direction can be changed to a certain extent. Thus, when the conveying module 2 transports workpieces of different sizes, the fixed position of the conveying module 2 can be adjusted so that the part of the workpiece to be welded is aligned with the welding head 31, ensuring the welding effect. This allows the ultrasonic welding machine to be applied to workpieces of different sizes, making its application range wider and its practicality stronger.

[0049] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
