Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts processing, and in particular to a welding device for faceplate decorative parts. Background Technology

[0002] In modern automobile manufacturing, the aesthetics and assembly precision of interior components are crucial factors in enhancing overall vehicle quality and user experience. As one of the components frequently touched by the driver, the gearshift cover receives particular attention for its design and assembly quality. For example... Figure 1 As shown, the end cap includes a square ring body one and a square ring body two, which are staggered, with the bottom ring body one having a larger outer diameter. To enhance the aesthetics and durability of the end cap, a faceplate needs to be welded to the outer wall of the ring body two to ensure that the faceplate can perfectly cover the end cap.

[0003] Traditional welding processes for the end cap and sleeve rely primarily on manual operation. The process involves the operator holding the end cap and sleeve, manually ensuring the sleeve fits snugly against the outer wall of the ring body, and then placing the assembly directly beneath the ultrasonic welding machine. The machine is activated via a foot switch, causing the ultrasonic welding head to descend and perform single-point welding. This method has the following drawbacks: because only one point can be welded at a time, the entire process requires constantly flipping the end cap and sleeve, repeating positioning and welding, resulting in low production efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a welding device for decorative face coverings. It has a simple structure and can weld all four sides of the end cap in one operation without flipping the end cap, which greatly improves the convenience of use.

[0005] This utility model discloses a welding device for a face mask decorative component, comprising:

[0006] The base plate has two moving mechanisms on its top; the two moving mechanisms are vertically arranged.

[0007] Each moving mechanism has two output ends, which can move in opposite directions; each output end is equipped with an ultrasonic welding mechanism.

[0008] The mold is located at the center of the four welding mechanisms.

[0009] As a preferred embodiment of this utility model, the moving mechanism includes:

[0010] A support plate is fixedly connected to the base plate; the support plate is located below the mold, and both ends of the support plate protrude from the mold.

[0011] A lead screw is rotatably mounted on the support plate along the length of the support plate; the lead screw has a positive thread and a negative thread on each side;

[0012] Two sliding plates are slidably mounted on the support plate along the axis of the lead screw; each sliding plate is fixed with a threaded sleeve; the ultrasonic welding mechanism is mounted on the sliding plate;

[0013] The two threaded sleeves are threaded to the forward thread and the reverse thread, respectively;

[0014] The power mechanism is used to drive the lead screw to rotate.

[0019] The sliding plate is threaded with a locking bolt that passes through a slotted hole.

[0020] As a preferred embodiment of this utility model, the mold includes: a main body and a base fixed to the bottom of the main body;

[0021] When in the welding position, the outer wall of the main body fits against the inner wall of the end cap, and the top wall of the base supports the bottom wall of the end cap.

[0022] As a preferred embodiment of this utility model, the mold further includes:

[0023] Four sleeves, one end of which is connected to the base plate, and the other end of which has a groove;

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0040] Example

[0041] Reference Figure 2 , Figure 4 and Figure 6 This embodiment provides a welding device for face mask decorative parts, including:

[0042] Base plate 1, with two moving mechanisms 2 mounted on its top; the two moving mechanisms 2 are vertically arranged; as shown... Figure 6 As shown, in order to prevent the two moving mechanisms 2 from interfering with each other, the two moving mechanisms 2 are staggered in the height direction. Only some parts of the moving mechanism 2 need to be adjusted. Since most of the parts of the two moving mechanisms 2 are the same, they are not discussed separately.

[0043] Each of the moving mechanisms 2 has two output ends, which can move in opposite directions; each output end is equipped with an ultrasonic welding mechanism 3; the two moving mechanisms 2 are arranged vertically, so that the four ultrasonic welding mechanisms 3 correspond to the four sides of the end cap respectively, and the end cap can be welded at multiple points at one time.

[0044] Mold 4 is located at the center of the four welding mechanisms;

[0045] The specific usage process of this device is as follows: First, place the end cap on the mold 4. Then, manually tighten the faceplate and cover the ring 6 of the end cap. First, operate one of the moving mechanisms 2 to move the two ultrasonic welding mechanisms 3 closer to the ring 6 of the end cap. The faceplate is welded to the ring 6 through the ultrasonic welding mechanism 3. Then, operate the other moving mechanism 2 to move the two ultrasonic welding mechanisms 3 closer to the ring 6 of the end cap and weld the faceplate to the ring 6 through the ultrasonic welding mechanism 3. After welding is completed, operate the two moving mechanisms 2 to move the ultrasonic welding mechanism 3 outward to detach from the end cap. Then, manually separate the end cap from the mold 4. Compared with the existing technology, this device does not require frequent flipping of the end cap. The end cap is only positioned once, which greatly reduces the time of repeated positioning and flipping. At the same time, it can automatically weld the outer surface of the end cap, which greatly improves the welding efficiency.

[0046] If each ultrasonic welding mechanism 3 is driven by a single power source, it would increase costs, and it would be inconvenient to control the synchronized movements of each power source. Therefore, as a preferred embodiment of this invention, [referring to...] Figure 7 The mobile mechanism 2 includes:

[0047] The support plate 21 is fixedly connected to the base plate 1; the support plate 21 is located below the mold 4, and both ends of the support plate 21 protrude from the mold 4.

[0048] The lead screw 22 is rotatably mounted on the support plate 21 along the length of the support plate 21; the lead screw 22 has a positive thread and a negative thread on both sides respectively, and the positive thread and the negative thread are symmetrical.

[0049] Two sliding plates 23 are slidably mounted on the support plate 21 along the axis of the lead screw 22; each sliding plate 23 is fixed with a screw sleeve 24; the ultrasonic welding mechanism 3 is mounted on the sliding plate 23;

[0050] Among them, the two screw sleeves 24 are threadedly connected to the forward thread and the reverse thread respectively;

[0051] The power mechanism 25 is used to drive the lead screw 22 to rotate. The power mechanism 25 is a servo motor.

[0052] The specific usage process of the moving mechanism 2 is as follows: When welding is required, the power mechanism 25 is started, which drives the lead screw 22 to rotate. Since the lead screw 22 has a forward thread and a reverse thread on both sides respectively, and the two sliding plates 23 are slidably installed on the support plate 21 along the axis of the lead screw 22, when the lead screw 22 rotates, it will drive the two threaded sleeves 24 and the sliding plates 23 to make linear movements in opposite directions. When the two sliding plates 23 approach each other, the two ultrasonic welding mechanisms 3 will synchronously approach the ring body 6 of the end cover and perform multi-point synchronous welding on the sleeve.

[0053] As a preferred embodiment of this utility model, refer to Figure 7 The ultrasonic welding mechanism 3 includes:

[0054] An ultrasonic generator 31 is fixed on a sliding plate 23;

[0055] Welding head 32 is installed at the output end of ultrasonic generator 31;

[0056] The specific working process of the ultrasonic welding mechanism 3 is as follows: the ultrasonic generator 31 is responsible for generating high-frequency vibration energy, which converts electrical energy into mechanical vibration and transmits it to the welding head 32 through the output end; the welding head 32 is installed at the output end of the ultrasonic generator 31 and is the part that directly acts on the welding material. The welding head 32 can be set as an intermittent type or an integral type as needed.

[0057] If the ultrasonic generator 31 is directly fixed to the sliding plate 23, it may cause a positional deviation between the welding head 32 and the ring body 6, making it impossible to adjust the welding position. As a preferred embodiment of this utility model, see [reference]. Figure 8 Both sides of the ultrasonic generator 31 are fixed with side plates 33, and the side plates 33 have strip holes 34 perpendicular to the moving direction of the sliding plate 23.

[0058] The sliding plate 23 is threaded with a locking bolt 35 that passes through the strip hole 34;

[0059] The design of the slot 34 allows for adjustment of the position of the ultrasonic generator 31 within a certain range, so that even if there are slight positional errors during installation or use, these errors can be corrected by loosening the locking bolt 35 and fine-tuning the ultrasonic generator 31. This flexibility is very important when dealing with workpieces of different sizes.

[0060] As a preferred embodiment of this utility model, refer to Figures 3-5 The mold 4 includes: a main body 41 and a base 42 fixed to the bottom of the main body 41;

[0061] When in the welding position, the outer wall of the main body 41 is in contact with the inner wall of the end cap, and the top wall of the base 42 supports the bottom wall of the end cap.

[0062] After the end cap is fitted onto the mold 4, the outer wall of the main body 41 fits tightly against the inner wall of the end cap, while the top wall of the base 42 supports the bottom wall of the ring 5, providing a stable platform for the entire welding process. Since the mold 4 itself has positioning and support functions, the operator only needs to place the end cap on the mold 4 to achieve quick and accurate assembly. This method greatly simplifies the preparation work, shortens the production cycle, and reduces the possibility of human error.

[0063] If mold 4 is fixedly connected to base plate 1, then mold 4 is not easy to disassemble, which will be very inconvenient when mold 4 needs maintenance. (Refer to...) Figure 2 and Figure 3 As a preferred embodiment of this utility model, mold 4 further includes:

[0064] Four sleeves 43, one end of which is connected to the base plate 1, and the other end of which has a groove;

[0065] Four fixing rods 44 are provided. One end of each fixing rod 44 is connected to the base 42, and the other end slides into the groove. In order to improve the stability of the base 42, the four fixing rods 44 are connected to the four corners of the base 42 respectively. At the same time, this installation method will not interfere with the moving mechanism 2.

[0066] If mold 4 needs to be replaced or maintained, simply hold mold 4 and lift it up to pull the fixing rod 44 out of sleeve 43 to easily disassemble mold 4, simplifying the operation process.

[0067] Without a fixing device, the position of the fixing rod 44 inside the sleeve 43 cannot be effectively fixed, and it is prone to movement due to external force or vibration. This will cause the base 42 to be unstable throughout the welding process. As a preferred solution of this utility model, refer to Figure 3 and Figure 5 The sleeve 43 is provided with a locking element 45 for locking the position of the fixing rod 44;

[0068] The locking element 45 can be a bolt handle, spring locking pin or other device. The locking element 45 can firmly fix the fixing rod 44 in the sleeve 43 to prevent it from moving due to external force or vibration during the welding process. This ensures that the base 42 remains stable throughout the welding operation, thereby improving the quality and accuracy of the welding.

[0069] As a preferred embodiment of this utility model, refer to Figure 5 The top of the groove is flared, which makes it easier for the fixing rod 44 to slide into the sleeve 43. It can be inserted smoothly without precise alignment, which greatly simplifies the installation process of the base 42 and improves the operating efficiency.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
