[0002] O-rings, also known as "fluoropolymer O-rings," are special high-temperature resistant fluoroplastics such as FEP or PFA. They are sealed products made by compounding an elastomer (fluoropolymer / silicone) inside using a special process. They combine the advantages of Teflon and rubber, and are both corrosion resistant and elastic.

[0003] Manual welding of O-rings is time-consuming and labor-intensive. When the welding machine is held by hand, it is difficult to fix the shape and the weld point is easy to move. The welding machine is very inefficient and the quality is difficult to guarantee. Summary of the Invention

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] First, let's describe the material clamping and rotating device. The material here is generally an O-ring, also known as a "fluorine-coated O-ring", or a similar soft material.

[0023] like Figure 1 As shown, the welding machine includes a base 100, a frame 200, a welding device 300, a rotating mechanism 400, and a clamping and placing mechanism 500.

[0024] like Figure 2 As shown, the base 100 includes a base plate 11, on which a rectangular through hole 12 is provided.

[0025] The frame 200 includes a column 201, a slide rail plate 202 mounted on the column 201, the slide rail plate 202 having a slide groove, and fixing plates 216 respectively provided above and below the column 201, the fixing plates 216 being used to install cylinders.

[0026] The first cylinder includes a cylinder body 204, a telescopic rod 206, and an adapter 208 connected to the free end of the telescopic rod 206. The second cylinder includes a cylinder body 205, a telescopic rod 207, and an adapter 208 connected to the telescopic rod 207. The cylinder body 204 of the second cylinder passes through the through hole 12 and is fixed below the base plate 11. The first and second cylinders are respectively mounted on the fixed plate 216, arranged vertically opposite each other. The slide plate includes two pieces, each comprising a slider 203, a fixed block 209, and an adapter plate 211. The adapter 208 of the cylinder is connected to the fixed block 209. The upper and lower sliders can move on the slide rail. The first and second cylinders drive the slide plates to move vertically relative to each other, thereby changing the distance between the two slide plates.

[0027] There are four heating rods 215, two on the top and two on the bottom, which are respectively installed on the mounting plate 213. The mounting plate is provided with a clamping plate 214 for fixing the heating rods 215. The mounting plate 213 is fixed on the workpiece 211, and the workpiece 211 is connected to the adapter plate 212.

[0028] As shown in the figure, the base includes a first base plate 42, which is connected to four pillars (44, 45, 46, 47). The first base plate has a through hole 401 in the middle. A cylinder 43 is provided below the through hole of the first base plate 42. The external dimensions of the cylinder 43 are larger than those of the first base plate 42 and it is fixed to the first base plate by bolts. An adapter plate 41 is provided on the cylinder 43 and passes through the through hole 401. A rotating plate 40 is provided on the adapter plate, and clamping devices are fixed at both ends of the rotating plate 40.

[0029] like Figure 3 As shown, the rotating mechanism 400 includes a base 42 with a through hole 401. The base is fixed to the base plate 11 by support columns (44, 45, 46, 47). A third cylinder is installed under the base 42 and fixed by bolts. The output shaft of the cylinder 43 is connected to the adapter plate 42, which can drive the adapter plate 42 to rotate 360 ​​degrees. A rotating plate 40 is installed on the adapter plate 42, so the cylinder 43 can drive the rotating plate 40 to rotate 180 degrees, thus changing the position of the two clamping devices 500.

[0030] like Figure 4 As shown, the clamping and placing mechanism 500 includes a connecting plate 50, which is fixedly connected to the rotating plate through a groove at the bottom. One end of the connecting plate 50 is provided with two fixing plates 57. One end of the first movable plate 58 and the second movable plate 52 are provided with fixing grooves 59, and the fixing plates are inserted into the fixing grooves 59. The first movable plate 58 is provided with a stepped platform 51, and the second movable plate is also provided with a stepped platform 52. The third movable plate 56 is provided on the stepped platform 51. The stepped platform 52 is provided with a through hole 55, which is preferably elliptical. The third movable plate 56 is provided with the through hole 56. The third movable plate is fixed to the first movable plate 58 by bolts passing through the through hole 55 and the through hole 56. Similarly, the fourth movable plate 54 is fixed on the third movable plate.

[0031] Among them, the through hole 55 is elliptical, so that the distance of the bolts can be adjusted to accommodate materials of different sizes.

[0032] The third movable plate 56 and the fourth movable plate 54 are driven by a cylinder to adjust the relative distance between them. The cylinder is not shown in the accompanying drawings of this invention.

[0033] like Figure 5 As shown, the third movable plate 56 and the fourth movable plate 54 have corresponding recessed cavities 501. These recessed cavities 501 are open, stepped, and the two corresponding cavities form a material placement cavity. This cavity can be elliptical, circular, or other shapes, used to place materials. The third movable plate 56 and the fourth movable plate 54 can be closed or have a certain gap. The gap can be adjusted by a cylinder (not shown in the figure). When placing or removing materials, the two movable plates separate; when processing the materials, the distance between the two movable plates decreases, clamping the materials. This better fixes the materials if they are elastic or soft, maintaining their shape. However, when handled manually, deformation is more likely, and it is difficult to fix the materials.

[0034] Two clamping and placing mechanisms 500 are provided, located at both ends of the rotating plate 40 respectively.

[0035] Of course, although the attached drawings only show two clamping and placement mechanisms 500, if more than two are provided, such as three or four clamping devices, the rotating plate only needs to be changed to have four or three ends. This is still a direct variation of the present invention and is still within the scope of the present invention.

[0036] The welding process will now be described.

[0037] like Figure 6As shown, the material to be welded in this invention is a package of fluoropolymer O-rings. Because O-rings are made of a soft material, their shape was difficult to maintain during manual processing, resulting in high welding difficulty, very low processing efficiency, and high labor costs.

[0038] First, the third movable plate 56 and the fourth movable plate 54 are in the open state, and the material is placed into the recess 501. Then, the cylinder drives the two movable plates to clamp the material, and the third cylinder drives the rotating plate 40 to rotate 180 degrees.

[0039] The first and second cylinders drive the sliding plates to move towards each other, reducing the distance between them. At this point, the four heating rods 215 are aligned with the material. The heating rods begin to operate, and after heating is complete, the first and second cylinders drive the sliding plates to open vertically. Then, the third cylinder drives the rotating plate 40 to rotate 180 degrees. At this time, the second material is also placed in the mirrored second clamping and placing cavity. The above steps are repeated to begin heating the second material. Since the heated material needs to be cooled, a cooling device, such as a cold air nozzle, can be installed on the base plate 11 to cool the heated material. After the other material has finished heating, and the first material has finished cooling, the third movable plate 56 and the fourth movable plate 54 are released, the recess 501 expands, and the first material is manually removed and the new material is placed in. The second round of processing then begins.

[0040] Compared to manual labor, the processing efficiency is several times higher, greatly reducing labor costs, while ensuring processing quality.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
