Description

Technical Field

[0001] This utility model relates to the field of welding equipment, and more specifically to an ultrasonic automatic welding equipment device. Background Technology

[0002] Ultrasonic welding is a welding method that uses high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other, forming a fusion between molecular layers.

[0003] Currently, ultrasonic welding of workpieces typically requires manual loading and unloading. While the welding process itself is very fast (usually only a fraction of a second to a few seconds), the manual loading and unloading is relatively time-consuming, becoming a bottleneck in the entire production cycle. This severely restricts the full utilization of equipment potential and the improvement of overall production efficiency, making it difficult to meet the demands of high-volume, high-paced production. Furthermore, the precision and stability of manual operation are difficult to guarantee. Even slight deviations in workpiece placement, angle, and force can lead to unstable welding quality (such as incomplete welds, over-welds, or positional misalignments), increasing the product defect rate and affecting the reliability and consistency of the final product.

[0027] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0028] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings, such as... Figure 1 As shown, an ultrasonic automatic welding device includes a workbench 10, a conveyor belt 11 on the workbench 10, a support plate 12 clamped onto the conveyor belt 11, a first support platform 13 fixed to the top of the support plate 12, a second support platform 14 on one side of the conveyor belt 11, an ultrasonic welding mechanism 100 above the second support platform 14, and a clamping and transporting mechanism 200 on the side of the conveyor belt 11 away from the second support platform 14. The clamping and transporting mechanism 200 is used to clamp the workpiece on the first support platform 13 and transport it to the second support platform 14.

[0029] In the working state of this embodiment, the workpiece to be ultrasonically welded is placed on the first support platform 13. When the conveyor belt 11 moves the first support platform 13 to one side of the second support platform 14 through the support plate 12, the first support platform 13 is located between the clamping and transporting mechanism 200 and the second support platform 14. Then, the clamping and transporting mechanism 200 is activated to clamp the workpiece on the first support platform 13 and transport it to the second support platform 14. Then, the ultrasonic welding mechanism 100 is activated to perform ultrasonic welding on the workpiece placed on the second support platform 14.

[0030] Compared with the prior art, this application utilizes a clamping and handling mechanism 200, which can automatically clamp the workpiece located on the conveyor belt 11 from the first support platform 13 and transport it to the second support platform 14 for automatic ultrasonic welding. The entire process, except for placing the workpiece, does not require manual intervention, has a high degree of automation, and can improve enterprise production efficiency while reducing labor costs.

[0031] Furthermore, based on the above embodiments, such as Figure 2 As shown, the ultrasonic welding mechanism 100 includes a first support 110, a first lifting device 120 mounted on the top of the first support 110, and an ultrasonic generator 130 mounted on the bottom of the first lifting device 120. A first connecting rod 140 is provided between the ultrasonic generator 130 and the first lifting device 120. The ultrasonic generator 130 includes a transducer, a focusing device, and a welding head, and can be connected to an external power source. Its working principle is existing technology and will not be described in detail here. When the clamping and transporting mechanism 200 clamps and transports the workpiece on the first support platform 13 to the second support platform 14, the first lifting device 120 is activated. The first connecting rod 140 drives the ultrasonic generator 130 to come into contact with the workpiece, and then the ultrasonic generator 130 is activated to perform ultrasonic welding.

[0032] Furthermore, based on the above embodiments, such as Figure 2As shown, the clamping and conveying mechanism 200 includes a second bracket 210. A first guide rail 220 is mounted on the top of the second bracket 210. The laying direction of the first guide rail 220 is perpendicular to the direction of the conveyor belt 11. A first sliding seat 230 is mounted on the first guide rail 220. A first rotary motor 240 is mounted on one end of the first guide rail 220. The first rotary motor 240 controls the first sliding seat 230 to slide along the first guide rail 220 via a conveyor belt (not shown in the figure). A second lifting device 250 is installed, and a clamping device 260 is installed at the bottom of the second lifting device 250. When the conveyor belt 11 moves the first support platform 13 to one side of the second support platform 14 through the support plate 12, the first rotary motor 240 is started to drive the second lifting device 250 to move above the first support platform 13. Then, the clamping device 260 is driven to descend and clamp the workpiece. Then, the second lifting device 250 is controlled to move above the second support platform 14, and then the workpiece is placed on the second support platform 14 for ultrasonic welding.

[0033] Furthermore, based on the above embodiments, such as Figure 3 As shown, the second lifting device 250 includes a vertically arranged second guide rail 251, a second sliding seat 252 is installed on the second guide rail 251, and a second rotary motor 253 is installed at the top of the second guide rail 251. The drive shaft of the second rotary motor 253 is connected to the second sliding seat 252 by a lead screw. That is, when the second rotary motor 253 drives the drive shaft to rotate, the second sliding seat 252 can move up and down along the second guide rail 251. A second connecting rod 254 is installed on the second sliding seat 252, and the clamping device 260 is installed at the end of the second connecting rod 254.

[0034] Furthermore, based on the above embodiments, such as Figure 3 As shown, the clamping device 260 includes a clamping cylinder 261. One end of the clamping cylinder 261 is fixed to the second connecting rod 254, and the other end is provided with a pair of clamping plates 262. When it is necessary to clamp a workpiece, the clamping cylinder 261 first controls the clamping plates 262 to move away in the opposite direction, and then waits until it moves to the vicinity of the workpiece before controlling the clamping plates 262 to move towards each other, thereby clamping the workpiece.

[0035] Furthermore, based on the above embodiments, such as Figure 1As shown, a positioning sensor 15 is provided between the conveyor belt 11 and the second support platform 14. The positioning sensor 15 is electrically connected to the clamping and transporting mechanism 200. When the conveyor belt 11 moves the first support platform 13 to one side of the second support platform 14 through the support plate 12, the positioning sensor 15 senses the first support platform 13 and sends an electrical signal to the clamping and transporting mechanism 200, thereby using the clamping and transporting mechanism 200 to clamp the workpiece on the first support platform 13 and transport it to the second support platform 14.

[0036] Furthermore, based on the above embodiments, such as Figure 1 As shown, a pre-pressing mechanism 300 is also provided on one side of the clamping and conveying mechanism 200. The pre-pressing mechanism 300 is used to pre-press the workpiece placed on the first support platform 13 from the top. After the pre-pressing is completed, the first support platform 13 is moved to one side of the second support platform 14 by the conveyor belt 11. This allows for a tighter assembly between the workpieces during ultrasonic welding, resulting in better welding performance for plate-shaped workpieces.

[0037] Furthermore, based on the above embodiments, such as Figure 4 As shown, the pre-pressing mechanism 300 includes a third support 310, a top plate 320 is mounted on the third support 310, a lifting cylinder 330 is fixed on the top plate 320, a connecting plate 340 is mounted through the top of the driving end of the lifting cylinder 330, and a pressing component 350 is provided at the bottom of the connecting plate 340. When the conveyor belt 11 moves the first supporting platform 13 to below the pre-pressing mechanism 300 through the supporting plate 12, the lifting cylinder 330 is activated to drive the connecting plate 340 and the pressing component 350 to descend simultaneously, thereby forming a pressing on the workpiece.

[0038] Furthermore, based on the above embodiments, such as Figure 4 As shown, a guide rod 360 is provided between the top plate 320 and the connecting plate 340. When the lifting cylinder 330 drives the connecting plate 340 and the pressing component 350 to descend, the guide rod 360 can guide the direction of descent of the connecting plate 340 and the pressing component 350.

[0039] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
