Description

Technical Field

[0001] This utility model relates to the field of welding processing technology, and specifically to a welding assembly structure for a filter cylinder. Background Technology

[0002] The carbon canister assembly is a key component in automotive evaporative emission control. It adsorbs and temporarily stores gasoline vapors from the fuel tank. Under specific operating conditions, the vehicle's electronic control unit (ECU) controls the carbon canister desorption solenoid valve to open. The negative pressure in the intake manifold causes fresh air from the outside to flow through the carbon canister, desorbing the gasoline vapors adsorbed on the activated carbon and sending them to the engine for combustion. In existing technology, the non-woven fabric inside is simply attached to the inner wall of the carbon canister without any fixation. This makes the non-woven fabric prone to "edge collapse," and its relative position is easily altered, causing significant inconvenience for subsequent carbon powder filling processes and affecting assembly efficiency.

[0003] Traditionally, welding carbon canisters is a manual operation. The canister is placed in a fixture, and then an ultrasonic welding machine is used to weld the non-woven fabric to the inner side of the canister. Because ultrasonic welding requires reaching inside the canister, the canister often shifts position, resulting in poor welding accuracy, low welding efficiency, high scrap rate, and high labor intensity for workers. This does not meet the requirements of mass production for enterprises. Utility Model Content

However, the embodiments described are not intended to limit the present invention.

[0028] Reference Figure 1-4 As shown, a filter cylinder welding assembly structure includes:

[0029] The positioning mechanism includes a positioning frame, on which a positioning fixture 7 is provided, and on which a positioning groove 71 matching the cylinder 8 is provided;

[0030] A lifting mechanism is provided below the positioning fixture 7. The lifting mechanism includes a lifting frame 53, which is drivenly connected to the driving component 5. A lifting fixture 4 that matches the bottom of the cylinder 8 is provided on the lifting frame 53. The driving component 5 is used to drive the lifting fixture 4 on the lifting frame 53 to lift and position the cylinder 8 on the positioning fixture 7.

[0031] Welding mechanism 1 is disposed above the positioning fixture 7. Welding mechanism 1 includes welding frame 13, ultrasonic welder 14 is disposed on welding frame 13, welding head 15 is disposed on ultrasonic welder 14, welding frame 13 is drivenly connected to lifting assembly, lifting assembly is used to drive the welding head 15 of ultrasonic welder 14 to extend into the cylinder 8 after lifting and positioning for ultrasonic welding.

[0032] The welding frame 13 is equipped with a pressing component 3, which is used to press and position the cylinder 8 on the positioning fixture 7 and the lifting fixture 4.

[0033] This invention uses the positioning groove 71 on the positioning fixture 7 to position the upper part of the cylinder 8. The driving component 5 drives the lifting fixture 4 on the lifting frame 53 to lift and position the cylinder 8 on the positioning fixture 7. The lifting component drives the welding head 15 of the ultrasonic welder 14 to extend into the lifted and positioned cylinder 8 to perform ultrasonic welding. This effectively ensures that the dimensions are accurate and meet the assembly requirements during ultrasonic welding. At the same time, the lifting component drives the welding head 15 into the cylinder 8, and the pressing component 3 presses and positions the cylinder 8 on the positioning fixture 7 and the lifting fixture 4. This achieves comprehensive positioning of the cylinder 8, ensures the stability of the cylinder 8 during the lifting process, avoids shaking that affects the subsequent ultrasonic welding accuracy, and improves the welding quality of the product.

[0034] In one embodiment of the present invention, the lifting assembly includes a lifting frame 11, a lifting guide rail 12 is provided on the lifting frame 11, the welding frame 13 is slidably mounted on the lifting guide rail 12, and a lifting cylinder 16 is provided on the lifting frame 11. The lifting cylinder 16 is drivenly connected to the welding frame 13, and the lifting cylinder 16 drives the welding frame 13 to move up and down reciprocally along the lifting guide rail 12.

[0035] Specifically, the lifting cylinder 16 drives the welding frame 13 to move downward along the lifting guide rail 12, which in turn drives the welding head 15 of the ultrasonic welder 14 on it to extend into the cylinder 8 after it has been lifted and positioned, and performs ultrasonic welding on the non-woven fabric parts inside the cylinder 8 and the inner wall of the cylinder 8. This process is efficient and improves the accuracy of ultrasonic welding.

[0036] In one embodiment of this utility model, a material blocking component 2 is provided on the lifting frame 11. The material blocking component 2 includes a material blocking frame 21, and a material blocking cylinder 22 is provided on the material blocking frame 21. The material blocking cylinder 22 is drivenly connected to the material blocking rod 23. The material blocking cylinder 22 is used to drive the material blocking rod 23 to pass through the moving path of the welding frame 13. A detection sensor 24 for detecting the position of the welding frame 13 is provided on the lifting frame 11.

[0037] Specifically, after ultrasonic welding is completed, the lifting cylinder 16 drives the welding frame 13 to move upward along the lifting guide rail 12. After the detection sensor 24 on the lifting frame 11 detects the position of the welding frame 13, the baffle cylinder 22 drives the baffle rod 23 to pass through the moving path of the welding frame 13. The lifting cylinder 16 drives the welding frame 13 to abut and support the baffle rod 23, preventing the welding frame 13 from falling and causing equipment damage. At the same time, it effectively extends the service life of the drive cylinder 52 and reduces production costs.

[0038] In one embodiment of the present invention, the pressing assembly 3 includes a pressing frame 31, which is mounted on a welding frame 13. A pressing rod 32 is mounted on the pressing frame 31, and a buffer spring 34 is sleeved on the pressing rod 32. A pressing block 33 is mounted on the free end of the pressing rod 32.

[0039] Specifically, one end of the buffer spring 34 abuts against the pressure block 33, and the other end abuts against the pressure frame 31. When the lifting assembly drives the welding head 15 of the ultrasonic welder 14 on the welding frame 13 to extend into the cylinder 8, the pressure rod 32 on the pressure block 33 moves upward and compresses the buffer spring 34, thereby pressing the top of the cylinder 8, so that the cylinder is more stably positioned on the lifting fixture 4. During the rising process, the bottom of the cylinder is supported and positioned by the lifting fixture 4, and the top of the cylinder 8 does not leave the positioning groove 71 and is positioned by the positioning fixture 7, ensuring the positioning accuracy of the cylinder 8 after it rises and improving the subsequent welding accuracy.

[0041] Specifically, the drive cylinder 52 drives the lifting frame 53 to move upward. The guide rod 54 passes through the guide sleeve of the drive frame 51. The lifting frame 53 is guided by the guide rod 54 to ensure the lifting accuracy of the cylinder 8 and avoid shaking that would affect the subsequent ultrasonic welding accuracy.

[0042] In one embodiment of the present invention, a support component 6 is provided at the bottom of the lifting frame 53. The support component 6 includes a support frame 62. A support cylinder 61 is provided on the drive frame 51. The support cylinder 61 is driven to connect with the support block 63. The support cylinder 61 drives the support block 63 to move so as to support the support frame 62 by lifting the material.

[0043] Specifically, when the support frame 62 on the lifting frame 53 rises a certain distance, the support cylinder 61 drives the support block 63 to move below the support frame 62, and at the same time, the drive cylinder 52 drives the lifting frame 53 to move downward, so that the support frame 62 falls onto the support block 63, thereby providing top support for the lifting fixture 4 and the cylinder 8, providing bottom support force for subsequent ultrasonic welding, avoiding problems such as deformation of the cylinder 8, and improving product processing quality.

[0044] In one embodiment of the present invention, guide plates 64 are provided on both sides of the drive frame 51, and guide grooves are provided on the guide plates 64. Guide strips 65 matching the guide grooves are provided on both sides of the support block 63, and the guide strips 65 pass through the guide grooves.

[0045] Specifically, the support block 63 is provided with guide bars 65 on both sides that match the guide groove. The guide bars 65 pass through the guide groove so that they can guide the movement direction of the support block 63, improve the movement accuracy of the support block 63, and enable it to effectively support the support frame 62.

[0046] In one embodiment of the present invention, the lifting fixture 4 includes a fixture plate 41, a reference block 42 is provided on the fixture plate 41, a positioning hole 43 on the reference block 42 that matches the bottom of the cylinder 8, and positioning blocks 44 are provided around the reference block 42, with positioning inclined surfaces provided on the positioning blocks 44.

[0047] Specifically, the bottom of the cylinder 8 is provided with a positioning groove 71 and is positioned opposite to the lifting fixture 4. The positioning hole 43 on the reference block 42 matches the protrusion at the bottom of the cylinder 8, so that the protrusion on the cylinder 8 is positioned by the positioning hole 43. Multiple positioning blocks 44 are provided around the reference block 42. The positioning bevels on the positioning blocks 44 support and position the bottom of the cylinder 8, effectively preventing the cylinder 8 from shaking during the lifting process.

[0048] In one embodiment of this utility model, the welding frame 13 includes a support plate 131, guide plates 132 are provided on both sides of the support plate 131, guide grooves 133 are provided on the guide plates 132, a sliding frame 134 is slidably arranged between the two guide grooves 133, an adjusting bolt 135 is rotatably provided on one side of the guide plate 132, the adjusting bolt 135 is connected to the sliding frame 134, a limit pin 136 is provided on the other side of the guide plate 132, the sliding frame 134 is locked on the limit pin 136, and a test sensor 137 for detecting the position of the sliding frame 134 is provided at the edge of the guide plate 132.

[0049] Specifically, the support plate 131 is provided with multiple holes for installing limit pins 136. The position of the limit pins 136 can be changed according to the specifications of different sliding frames 134 and processing requirements. The sliding frame 134 is brought close to the limit pins 136. Multiple test sensors 137 detect the position of the sliding frame 134. At the same time, the adjusting bolts 135 are rotated to adjust the relative position of the sliding frame 134 and the support plate 131, so that the ultrasonic welder 14 on the sliding frame 134 always maintains a vertical state. The ultrasonic welder 14 can be finely adjusted in position, which is convenient and improves the processing accuracy.

[0050] In one embodiment of the present invention, the positioning groove 71 is provided with a guide arc surface 72 at its edge, the guide arc surface 72 is in the shape of a flared mouth, and the positioning fixture 7 is provided with openings 73 on both sides, the openings 73 being connected to the positioning groove 71.

[0051] Specifically, the positioning groove 71 is provided with a guide arc surface 72 on its edge. The guide arc surface 72 has a flared structure, which can easily guide the cylinder 8 to be placed in the positioning groove 71 to ensure feeding efficiency. The positioning fixture 7 has openings 73 on both sides to facilitate the loading and unloading of the cylinder 8. It is easy to use and effectively avoids deformation of the cylinder 8 when loading and unloading materials.

[0052] Usage process

[0053] The cylinder 8 is placed on the positioning fixture 7. The bottom of the cylinder 8 has a positioning groove 71 that passes through it and is positioned opposite the lifting fixture 4. The positioning hole 43 on the reference block 42 matches the protrusion on the bottom of the cylinder 8, allowing the protrusion on the cylinder 8 to be positioned by passing through the positioning hole 43. Multiple positioning blocks 44 are arranged around the reference block 42. The positioning bevels on the positioning blocks 44 support and position the bottom of the cylinder 8, effectively preventing the cylinder 8 from swaying during the lifting process. During the ascent, its bottom is supported and positioned by the lifting fixture 4. The top of cylinder 8 remains in the positioning groove 71 and is positioned by the positioning fixture 7 to ensure the positioning accuracy of cylinder 8 after it rises, thus improving the subsequent welding accuracy. The drive cylinder 52 drives the lifting frame 53 to move upward. The guide rod 54 passes through the guide sleeve of the drive frame 51 and guides the lifting of the lifting frame 53 to ensure the lifting accuracy of cylinder 8 and avoid swaying that could affect the subsequent ultrasonic welding accuracy. When the support frame 62 on the lifting frame 53 rises a certain distance, the support cylinder 61 drives the support block 63 to move to the support position. Below the support frame 62, the drive cylinder 52 simultaneously moves the lifting frame 53 downwards, causing the support frame 62 to fall onto the support block 63, thus providing support for the lifting fixture 4 and the cylinder 8. This provides bottom support for subsequent ultrasonic welding, preventing deformation of the cylinder 8 and improving product processing quality. The lifting cylinder 16 moves the welding frame 13 downwards along the lifting guide rail 12, causing the welding head 15 of the ultrasonic welder 14 on it to extend into the lifted and positioned cylinder 8, and to weld the non-woven fabric parts inside the cylinder 8. The component is ultrasonically welded to the inner wall of the cylinder 8. After ultrasonic welding is completed, the lifting cylinder 16 drives the welding frame 13 to move upward along the lifting guide rail 12. After the detection sensor 24 on the lifting frame 11 detects the position of the welding frame 13, the baffle cylinder 22 drives the baffle rod 23 to pass through the moving path of the welding frame 13. The lifting cylinder 16 drives the welding frame 13 to abut against the baffle rod 23 for support, preventing the welding frame 13 from falling and causing equipment damage. At the same time, it effectively extends the service life of the drive cylinder 52 and reduces production costs.
