Description

Technical Field

[0001] The utility model relates to the field of ultrasonic welding equipment, in particular to a product automatic protective film supporting mechanism. Background Art

[0002] In traditional ultrasonic welding operations, the operator puts the assembled product (base and upper cover) into the ultrasonic welding machine imitation tooling, and then the operator manually puts the Teflon film that protects the product on the product. The film is used to buffer the impact of the ultrasonic generator contacting the high-speed shock wave of the product on the product. After that, the equipment is started, the ultrasonic fixture descends to perform ultrasonic welding, and the product base and the cover are ultrasonically welded together. Finally, the operator manually removes the protective film and then takes out the welded product. The removal and placement of protective films such as films in existing ultrasonic welding requires cumbersome manual operations, which is not conducive to rapid production. In other ultrasonic welding operations, there is an automatic winding output device for the film for output, and a single lifting cylinder is used to control the film to move up and down to fit the product. However, when the single lifting cylinder fails, the film cannot move. During the descent of the ultrasonic fixture, the film will be pulled due to the height difference between the film and the product, causing creases or tears, and the product cannot be protected. Therefore, the work can only be stopped for maintenance and cannot be continued. Utility Model Content

[0018] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0019] Please refer to Figure 1 to Figure 2 A product automatic protective film supporting mechanism comprises a first frame 1, a second frame 4, a release wheel 3, a tightening wheel 6, a first lifting cylinder 2, a second lifting cylinder 5, a film 7 and a height adjustment component; the first frame 1 is connected to the first lifting cylinder 2, and the second frame 4 is connected to the second lifting cylinder 5; the first frame 1 is provided with a release wheel 3, and the second frame 4 is provided with a tightening wheel 6; the film 7 is wound from the release wheel 3 to the tightening wheel 6; the height adjustment component is connected to the first lifting cylinder 2 and the second lifting cylinder 5, and the first lifting cylinder 2 and the second lifting cylinder 5 are movable along the height direction of the height adjustment component.

[0020] From the above description, it can be seen that the beneficial effect of the utility model is that: during the ultrasonic welding process, the first frame 1 and the second frame 4 can be moved down by controlling the action of the first lifting cylinder 2 and the second lifting cylinder 5, and the corresponding film 7 between the release wheel 3 and the tightening wheel 6 is moved down to cover the product to be processed to form a processing protective film; after the ultrasonic welding is completed, the first frame 1 and the second frame 4 are moved up, and the tightening wheel 6 rotates to move the new film 7 between the first frame 1 and the second frame 4 to prepare for the next processing. The above design avoids the cumbersome operation of manual film covering, and at the same time, the arrangement of multiple lifting cylinders, when one of the cylinders fails, can also be moved down by another lifting cylinder to make the film 7 partially contact with the product, and then when the working end of the ultrasonic welding moves down, it is pressed to cover the entire product, and there will be no failure and stop working when the single cylinder control occurs; in addition, the design of the height adjustment component can adjust the height of the first frame 1 and the second frame 4 according to the size of the product, so as to reduce the working stroke of the lifting cylinder, extend its service life, and ensure that the overall device runs more stably.

[0021] Furthermore, the height adjustment assembly includes a first fixed seat 8, a first screw rod 10 and a first adjustment handle 12. The first fixed seat 8 is provided with a rotatable first screw rod 10, the first screw rod 10 is parallel to the height direction of the first frame 1, and the upper end of the first screw rod 10 is connected to the first adjustment handle 12; the first lifting cylinder 2 is connected to the first screw rod 10.

[0022] From the above description, it can be seen that the first screw rod 10 is arranged on the first fixed seat 8. By rotating and adjusting the first adjustment handle 12, the first screw rod 10 is rotated to drive the first lifting cylinder 2 to move in the length direction of the screw rod, thereby adjusting the height of the first frame 1, so that the downward movement distance of the film 7 covering the product is reduced, thereby reducing the working stroke of the first lifting cylinder 2.

[0023] Furthermore, the height adjustment assembly also includes a second fixed seat 9, a second screw rod 11 and a second adjustment handle 13. The second fixed seat 9 is provided with a rotatable second screw rod 11, the second screw rod 11 is parallel to the height direction of the second frame 4, and the upper end of the second screw rod 11 is connected to the second adjustment handle 13; the second lifting cylinder 5 is connected to the second screw rod 11.

[0024] From the above description, it can be seen that the second screw rod 11 is arranged on the second fixed seat 9. By rotating and adjusting the second adjustment handle 13, the second screw rod 11 is rotated to drive the second lifting cylinder 5 to move in the length direction of the screw rod, thereby adjusting the height of the second frame 4, so that the downward movement distance of the film 7 covering the product is reduced, thereby reducing the working stroke of the second lifting cylinder 5.

[0025] Furthermore, the height adjustment assembly also includes a first support seat 14 and a second support seat 15, the first support seat 14 is connected to the first fixed seat 8, and the second support seat 15 is connected to the second fixed seat 9; the first support seat 14 and the second support seat 15 are both L-shaped structures with a connected vertical plate 16 and a horizontal plate 17, and a triangular reinforcement plate 18 is connected between the vertical plate 16 and the horizontal plate 17.

[0026] From the above description, it can be seen that the first fixed seat 8 and the second fixed seat 9 are supported by the first support seat 14 and the second support seat 15; the vertical plates 16 of the first support seat 14 and the second support seat 15 are respectively connected to the corresponding fixed seats, and the horizontal plate 17 is connected to the placement platform; in addition, the triangular reinforcement plate 18 connected between the vertical plate 16 and the horizontal plate 17 is used to improve the strength and supporting performance of the two support seats.

[0027] Furthermore, a plurality of rollers are respectively disposed on the first frame 1 and the second frame 4 , and the rollers can be used for winding the film 7 .

[0028] From the above description, it can be seen that through the design of multiple rollers on the first frame 1 and the second frame 4, when matching films 7 of different lengths and thicknesses, the film 7 can be wound on multiple rollers to ensure that it remains in a taut state, so that its own stress can be released, thereby avoiding creases when the subsequent film 7 is covered, resulting in protection failure.

[0029] Furthermore, the roller includes a height adjustment roller 19 , and the height adjustment roller 19 on the first frame 1 is arranged at the lower side of the release wheel 3 ; the height adjustment roller 19 on the second frame 4 is arranged at the lower side of the tightening wheel 6 .

[0030] From the above description, it can be seen that by arranging the height adjustment roller 19 at the lower side of the release wheel 3 and the tightening wheel 6, when adjusting the working stroke of the lifting cylinder according to the product height, the height of the film 7 can be lowered by winding the film 7 onto the height adjustment roller 19, thereby adapting to the product size without adjusting the height adjustment component or the working stroke of the lifting cylinder.

[0031] Furthermore, the first frame 1 and the second frame 4 are provided with a plurality of reserved holes 20 for roller shaft installation.

[0032] It can be seen from the above description that, through the design of the reserved hole position 20 , additional rollers can be provided when the winding is adjusted according to the length and size of the film 7 in the later stage.

[0033] Furthermore, it also includes a first sensor 21 , which is arranged at one side of the release wheel 3 to detect the remaining amount of the film 7 on the release wheel 3 .

[0034] As can be seen from the above description, the first sensor 21 is used to detect the amount of the material roll on the release wheel 3, so as to timely sense and notify the operator to replenish the material roll when the material is insufficient.

[0035] Furthermore, it also includes a close-position brake 22 , which is connected to the release wheel 3 .

[0036] As can be seen from the above description, the rotation of the release wheel 3 can be directly adjusted by the tight brake 22, so that the arranged film 7 can be further adjusted and tightened to ensure that the film 7 will not have creases and fits tightly to the product.

[0037] Embodiment 1:

[0038] Application scenario: During ultrasonic welding operations, the film 7 is output through an automatic winding output device, and a single lifting cylinder is used to control the film 7 to move up and down to fit the product. When the single lifting cylinder fails, the film 7 cannot move. During the descent of the ultrasonic jig, the film 7 will be pulled due to the height difference between the film 7 and the product, causing creases or tears, making it impossible to protect the product. As a result, the operation can only be stopped for maintenance and cannot be continued.

[0039] like Figure 1 and Figure 2 As shown, the product automatic protection film support mechanism of this embodiment includes a first frame 1, a second frame 4, a release wheel 3, a tightening wheel 6, a first lifting cylinder 2, a second lifting cylinder 5, a film 7, a height adjustment component, a first sensor 21 and a tight brake 22.

[0040] The product's automatic protective film support mechanism is used for ultrasonic welding and is located entirely under the ultrasonic jig.

[0041] The first frame 1 and the second frame 4 are respectively located on the left and right sides of the ultrasonic fixture, the first frame 1 is connected to the first lifting cylinder 2, and the second frame 4 is connected to the second lifting cylinder 5; the first frame 1 is provided with a release wheel 3 and multiple rollers, and one end of the release wheel 3 is connected to an operable tight brake 22. The second frame 4 is provided with a tightening wheel 6 and multiple rollers, and the tightening wheel 6 is connected to a motor.

[0042] The film 7 is wound from the release wheel 3 of the first frame 1 to a plurality of rollers on the same frame, and then wound with a plurality of rollers on the second frame 4 , and finally wound on the take-up wheel 6 .

[0043] The above-mentioned rollers include a height adjustment roller 19 and a tensioning roller. The height adjustment roller 19 of the first frame 1 is arranged at the lower side of the release wheel 3, and the tensioning roller of the first frame 1 is arranged at the left side of the release wheel 3; the height adjustment roller 19 of the second frame 4 is arranged at the lower side of the tensioning wheel 6, and the tensioning roller of the second frame 4 is arranged at the right side of the tensioning wheel 6.

[0044] During use, the winding form of the film 7 can be adjusted according to its length and thickness. By winding multiple tensioning rollers, the stress distribution of the film 7 can be improved to avoid the formation of wrinkles and creases. In addition, the height of the film 7 output can be adjusted by winding the film 7 through the height adjustment roller 19, so that it can be adapted to small-sized products without additionally adjusting the height of the first frame 1 and the second frame 4.

[0045] In addition, a plurality of reserved holes 20 for roller installation are provided on the first frame 1 and the second frame 4, which can be used to install other rollers.

[0046] The height adjustment assembly is connected to the first lifting cylinder 2 and the second lifting cylinder 5, and the first lifting cylinder 2 and the second lifting cylinder 5 are movable along the height direction of the height adjustment assembly. Specifically, the height adjustment assembly includes a first fixed seat 8, a first screw rod 10, a first adjustment handle 12, a second fixed seat 9, a second screw rod 11, a second adjustment handle 13, a first support seat 14 and a second support seat 15.

[0047] The first support seat 14 is connected to the first fixed seat 8, and the second support seat 15 is connected to the second fixed seat 9; the first support seat 14 and the second support seat 15 are both L-shaped structures with a connected vertical plate 16 and a horizontal plate 17, and a triangular reinforcement plate 18 is connected between the vertical plate 16 and the horizontal plate 17.

[0048] The first fixed seat 8 is provided with a rotatable first screw rod 10, the first screw rod 10 is parallel to the height direction of the first frame 1, and the upper end of the first screw rod 10 is connected to a first adjustment handle 12; the first lifting cylinder 2 is connected to the first screw rod 10. The second fixed seat 9 is provided with a rotatable second screw rod 11, the second screw rod 11 is parallel to the height direction of the second frame 4, and the upper end of the second screw rod 11 is connected to a second adjustment handle 13; the second lifting cylinder 5 is connected to the second screw rod 11.

[0049] The first frame 1 is further provided with a first sensor 21 . The first sensor 21 is provided at one side of the release wheel 3 to detect the amount of residual film 7 on the release wheel 3 .

[0050] Working principle: During ultrasonic welding, the product placement platform moves to the lower side of the mechanism. Then the tightening wheel 6 rotates to move the film 7, and the product faces the new film 7. Then, under the action of the first lifting cylinder 2 and the second lifting cylinder 5, the first frame 1 and the second frame 4 move down, and the film 7 moves down to fit closely with the surface of the product, and then the ultrasonic jig moves down to perform welding.

[0051] When the lifting cylinder on one side fails, since the other lifting cylinder still keeps working, the film 7 also moves downward on one side and becomes inclined. The film 7 can fit part of the product, and then under the downward pressure of the ultrasonic jig, the film 7 can also be completely attached to the product. Compared with the case where a single cylinder fails, the downward ultrasonic jig will not pull the film 7 excessively and cause it to deform or tear.

[0052] When adjusting the intrinsic stress caused by the thickness and size of the film 7, the film 7 can be wound on multiple rollers to ensure that it is stretched tight without generating creases.

[0053] The mechanism can also adjust the lifting position of the first frame 1 and the second frame 4 according to the size of the product. By rotating the first adjustment handle 12 and the second adjustment handle 13, the first frame 1 and the first lifting cylinder 2, the second frame 4 and the second lifting cylinder 5 can be adjusted to reduce the lifting position under the action of the first screw rod 10 and the second screw rod 11. In addition, the film 7 can be wound to the height adjustment roller 19 to adapt to small-sized products.

[0054] In summary, the product automatic protective film support mechanism provided by the utility model can control the action of the first lifting cylinder and the second lifting cylinder during the ultrasonic welding process, so that the first frame and the second frame move downward, and the corresponding film between the release wheel and the tightening wheel moves downward to cover the product to be processed to form a processing protective film; after the ultrasonic welding is completed, the first frame and the second frame move upward, and the tightening wheel rotates to move the new film between the first frame and the second frame to prepare for the next processing. The above design avoids the cumbersome operation of manual film covering. At the same time, the arrangement of multiple lifting cylinders can also make the film part contact with the product through the downward movement of another lifting cylinder when one of the cylinders fails, and then press it against the product when the working end of the ultrasonic welding moves downward to cover the entire product, and there will be no failure and stoppage of work when the single cylinder control occurs; in addition, the design of the height adjustment component can adjust the height of the first frame and the second frame according to the size of the product, thereby reducing the working stroke of the lifting cylinder, extending its service life, and ensuring that the overall device operates more stably.
