Description

Technical Field

[0001] This utility model relates to ultrasonic welding devices, and more particularly to an automatic ultrasonic welding device for electrodialysis partitions. Background Technology

[0002] In an electrodialysis unit, the baffle is a frame device sandwiched between the anion and cation membranes, thus forming either the desalination chamber or the concentrate chamber. The baffle supports and separates the anion and cation membranes, preventing membrane overlap and short circuits. It also forms a water flow channel, ensuring uniform water distribution and generating turbulence for stirring, thereby promoting ion diffusion and improving desalination efficiency while reducing power consumption.

[0003] Electrodialysis partitions need to be welded. Existing ultrasonic welding machines generally use manual feeding, which is not only inefficient, but also often causes the electrodialysis partitions to shift during welding, resulting in misalignment of the welding position. Utility Model Content

[0004] In the existing technology, the electrodialysis partition is prone to displacement during welding, resulting in insufficient welding position. Therefore, this utility model provides an ultrasonic automatic welding device for electrodialysis partitions.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] An ultrasonic automatic welding device for electrodialysis partitions includes a machine base and a welding head movably mounted above the machine base via a movable lifting assembly. A welding area is provided on the machine base surface. Limiting baffles with a spacing equal to the width of the electrodialysis partition are provided on both the front and rear sides of the welding area. A right lifting plate and a left lifting plate are respectively provided on the right and left sides of the welding area, with a spacing equal to the length of the electrodialysis partition. Both the right and left lifting plates are driven by cylinders. An annular boss is provided at the output end of the cylinder, and a compression spring is provided on the annular boss. The top of the compression spring acts on the right and left lifting plates respectively. Each right and left lifting plate has a cavity containing a clamping structure, which includes:

[0007] The first slider is tilted downwards and is installed inside the right and left lifting plates;

[0008] A reset mechanism is disposed within the cavity and applies a reset elastic force to the first slider;

[0009] The second slider is horizontally slidably disposed within the right and left lifting plates, and it is engaged with the top of the first slider through a set of abutting inclined surfaces.

[0010] The third slider is located at the output end of the cylinder and its top end is engaged with the second slider through a set of inclined surfaces.

[0011] In use, the output end of the cylinder rises and the right and left lifting plates rise through the support of the compression spring. When the right and left lifting plates rise to their limit positions, the cylinder continues to rise, causing the third slider to push the second slider to slide. The second slider pushes the first slider to slide diagonally downward and extend to press and fix the electrodialysis partition. After fixing, the electrodialysis partition is limited and fixed in all directions, and welding can be performed at the predetermined position by adjusting the welding head.

[0012] Preferably, the right lifting plate and the left lifting plate are vertically slidably mounted on the platform of the welding area, and both are provided with a limiting platform at their bottom. When raised, the limiting platform abuts against the bottom surface of the platform to form a limit.

[0013] Preferably, the reset mechanism includes a reset platform disposed on the side of the first slider, a reset groove located in the mounting cavity, and a reset spring disposed in the reset groove. The reset spring abuts against the reset platform so that after being pressed, it applies a reset elastic force to the reset platform to reset the first slider.

[0014] Preferably, the machine platform is also equipped with a feeding area, which has an L-shaped slide that matches the size of the electrodialysis partition. There are two pushing cylinders at the inlet and corner of the slide, and each pushing cylinder has a pushing plate at its output end. When feeding, the electrodialysis partition is placed at the inlet and pushed to the corner by the pushing cylinder at the inlet. The pushing cylinder at the corner then pushes the electrodialysis partition into the welding area and abuts against the right lifting plate.

[0015] Preferably, the width from the inlet of the slide to the corner is the same as the length of the electrodialysis baffle, and the width after the corner of the slide is the same as the width of the electrodialysis baffle. This part is opposite to the welding area between the two limiting baffles, so that the electrodialysis baffle can be pushed into the space between the two limiting baffles.

[0016] Preferably, a pressure sensor is provided on the right lifting plate. When the electrodialysis partition is pushed in, the pressure sensor senses the pressure signal and feeds back to control the lifting of the left lifting plate.

[0017] Preferably, the mobile lifting assembly includes a gantry frame slidably mounted on the machine platform, a sliding seat slidably mounted on the gantry frame, and a lifting platform mounted on the sliding seat. Both the gantry frame and the sliding seat are driven by a motor in conjunction with a gear and rack mechanism; the lifting platform is driven to lift via a screw mechanism.

[0018] Compared with the prior art, the advantages of this utility model are as follows: This application sets two limiting baffles and two lifting plates, and sets a pressing structure inside the lifting plates. When driving the lifting plates to rise, a compression spring is used to transmit force so that the lifting plates rise first. When the lifting plates continue to be driven, the pressing structure acts to press the electrodialysis partition. After pressing, the electrodialysis partition is completely positioned and locked. Then, the ultrasonic welding head moves to the preset position for welding, realizing automatic positioning and automatic pressing of the electrodialysis partition to ensure the accuracy of the welding position.

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0027] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures. Example

[0028] This embodiment mainly describes the title of the portable unmanned aerial vehicle (UAV) take-off and landing platform, as follows:

[0029] See attached document Figures 1-5 An ultrasonic automatic welding device for electrodialysis partitions includes a machine base 10 and a welding head 303 movably mounted above the machine base 10 via a movable lifting assembly. A welding area 101 is provided on the machine base 10. Limiting baffles 103 with a spacing equal to the width of the electrodialysis partition are provided on both the front and rear sides of the welding area 101. A right lifting plate 202 and a left lifting plate 201, respectively, are provided on the right and left sides of the welding area 101. The spacing between the right lifting plate 202 and the left lifting plate 201 is equal to the length of the electrodialysis partition. Both the right lifting plate 202 and the left lifting plate 201 are driven by a cylinder 401. An annular boss 4011 is provided at the output end of the cylinder 401. A compression spring 402 is provided on the annular boss 4011, and the top of the compression spring 402 acts on the right lifting plate 202 and the left lifting plate 201, respectively. Both the right lifting plate 202 and the left lifting plate 201 have cavities containing a clamping structure. The clamping structure includes:

[0030] The first slider 405 is inclined and slids downward within the right lifting plate 202 and the left lifting plate 201;

[0031] A reset mechanism is disposed within the cavity and applies a reset elastic force to the first slider 405;

[0032] The second slider 404 is horizontally slidably disposed within the right lifting plate 202 and the left lifting plate 201, and is engaged with the top of the first slider 405 through a set of abutting inclined surfaces.

[0033] The third slider 403 is located at the output end of the cylinder 401 and its top end is engaged with the second slider 404 through a set of abutting inclined surfaces.

[0034] In use, the output end of cylinder 401 rises and supports the right lifting plate 202 and the left lifting plate 201 to rise through the compression spring 402. When the right lifting plate 202 and the left lifting plate 201 rise to their limit positions, cylinder 401 continues to rise, causing the third slider 403 to push the second slider 404 to slide. The second slider 404 pushes the first slider 405 to slide obliquely downward and extend to press and fix the electrodialysis partition. After fixing, the electrodialysis partition is limited and fixed in all directions, and welding can be performed at the predetermined position by adjusting the welding head 303. In this design, cylinder 401 performs a two-stage lifting motion. During the first stage, the lifting plate is raised to its limit position. Then, the compression spring 402 is further compressed, and the third slider 403 continues to slide upward, sequentially pushing the second slider 404 and the first slider 405. This causes the first slider 405 to press the electrodialysis partition tightly. In addition, during feeding, the right lifting plate 202 is in the raised state, and the left lifting plate 201 is in the retracted state. After feeding, the left lifting plate 201 rises, and the cylinders 401 on both sides push out the first slider 405 to press and position the electrodialysis partition tightly. Welding is then performed to ensure the accuracy of the welding position.

[0035] Preferably, the right lifting plate 202 and the left lifting plate 201 are vertically slidably disposed on the table surface of the welding area 101, and both are provided with a limiting platform at their bottom. When raised, the limiting platform abuts against the bottom surface of the table surface to form a limit.

[0036] Preferably, the reset mechanism includes a reset platform 4051 disposed on the side of the first slider 405, a reset groove located in the mounting cavity, and a reset spring 4052 disposed in the reset groove. The reset spring 4052 abuts against the reset platform 4051 so that after being pressed, it applies a reset elastic force to the reset platform 4051 to reset the first slider 405. After the first slider 405 is reset, the lifting plate can be lowered, thereby pushing the partition plate out from the right side to feed the material.

[0037] Preferably, the machine platform 10 is also provided with a feeding area 102. The feeding area 102 is equipped with an L-shaped slide that matches the size of the electrodialysis partition. Two pusher cylinders 104 are provided at the inlet and corner of the slide. The output end of each pusher cylinder 104 is provided with a pusher plate 1041. When feeding, the electrodialysis partition is placed at the inlet and pushed to the corner by the pusher cylinder 104 at the inlet. The pusher cylinder 104 at the corner then pushes the electrodialysis partition into the welding area 101 and abuts against the right lifting plate 202.

[0038] Preferably, the width from the inlet of the slide to the corner is the same as the length of the electrodialysis partition, and the width after the corner of the slide is the same as the width of the electrodialysis partition. This part is opposite to the welding area 101 between the two limiting baffles 103, so that the electrodialysis partition can be pushed into the space between the two limiting baffles 103.

[0039] Preferably, the right lifting plate 202 is equipped with a pressure sensor. When the electrodialysis partition is pushed in, the pressure sensor senses the pressure signal and feeds back to control the lifting of the left lifting plate 201.

[0040] Preferably, the mobile lifting assembly includes a gantry 301 slidably mounted on the machine base 10, a sliding seat 302 slidably mounted on the gantry 301, and a lifting platform mounted on the sliding seat 302. Both the gantry 301 and the sliding seat 302 are driven by a motor in conjunction with a gear and rack mechanism; the lifting platform is driven to lift by a screw mechanism.

[0041] It should be noted that each of the three sliders has a corresponding slide rail—a vertical slide rail, a horizontal slide rail, and an inclined slide rail. The bottom of the lifting plate is provided with a countersunk hole, with the vertical slide rail located at the top of the countersunk hole. In addition, each lifting plate is equipped with two sets of clamping structures and two cylinders 401, and the two cylinders 401 are driven synchronously.

Specific examples have been used to illustrate the principle and implementation of this utility model. The above description of the embodiments is only for the purpose of helping to understand this utility model and its core ideas. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
