Description

Technical Field

[0001] The utility model relates to the technical field of power bank processing, in particular to a part welding device for power bank assembly. Background Art

[0002] Today, with the increasing popularity of portable electronic devices, the power bank, as an important mobile power product, has become a necessity in people's daily lives. To ensure the durability and safety of the power bank, its outer shell is usually made of plastic material and sealed and fixed through ultrasonic welding technology. This welding method can not only provide good waterproof and dustproof performance but also ensure the safety of internal components.

[0003] Traditionally, during the power bank assembly process, when using ultrasonic welding to connect the upper and lower plastic outer shells, a specially designed mold system is adopted. This system usually includes two main components: a fixed mold (usually the lower mold) for precisely positioning the power bank, and another movable mold (usually the upper mold) that can move up and down to apply pressure. After the power bank is placed in the fixed mold, the movable mold presses down on the upper outer shell of the power bank, and then the ultrasonic welding process is started. By using high-frequency vibration, frictional heat is generated between plastic molecules, causing them to melt and bond together, thus completing the firm connection of the outer shell.

[0004] However, the existing ultrasonic welding devices have certain limitations. Specifically, to ensure the stable position of the power bank during the welding process, the fixed mold often has positioning structures in the front, back, left, and right directions to limit the movement of the power bank. Although such a design helps to improve the welding accuracy, it also brings a problem - that is, it becomes relatively difficult to take out the finished product from the mold after welding. Because these additional limiting measures require the operator to spend more time and effort to adjust the angle or use tools to smoothly take out the welded power bank, which not only reduces the production efficiency but also may increase the risk of manual damage. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides a part welding device for power bank assembly, which has a simple structure, improves the structure of the lower mold, makes the blanking convenient, and improves the welding efficiency.

[0006] The part welding device for power bank assembly of the utility model includes a base. A placement table is arranged on the top of the base. The interior of the placement table is hollow and two through holes are communicated with the top. A positioning plate is slidably connected at each through hole. The two positioning plates are symmetrically arranged. The device also includes a driving mechanism one for driving the two positioning plates to move up and down; a push plate is slidably connected to the side of the placement table, and the device also includes a driving mechanism two for driving the push plate to slide;

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the "embodiment" mentioned here refers to specific features, structures or characteristics that can be included in at least one implementation mode of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0025] Embodiment

[0026] Referring to Figures 1 - 3 , this embodiment provides a part welding device for power bank assembly, including a base 1. A placing table 2 is arranged on the top of the base 1. The inside of the placing table 2 is hollow and two through holes are communicated with the top. The through holes are arranged in the vertical direction. A positioning plate 3 is slidably connected at each through hole. In order to improve stability, one end of a telescopic rod 21 is fixed to both sides of the bottom of the positioning plate 3, and the other end of the telescopic rod 21 is fixedly connected to the inner bottom of the placing table 2. The two positioning plates 3 are symmetrically arranged, and a first driving mechanism for driving the two positioning plates 3 to move up and down is further included; a pushing plate 4 is slidably connected to the side of the placing table 2, and a second driving mechanism for driving the pushing plate 4 to slide is further included; a lifting mechanism 5 is arranged on the top of the base 1, and the output end of the lifting mechanism 5 is an upper mold 6;

[0027] In this embodiment, during use, through the first driving mechanism, the positioning plate 3 protrudes from the top surface of the placing table 2. Then, the preliminarily formed power bank is placed on the placing table 2 and is located between the two positioning plates 3. Then, the lifting mechanism 5 is operated to lower the upper mold 6. The upper mold 6 will apply uniform pressure to the power bank and at the same time transmit ultrasonic energy to melt the plastic and achieve connection. After welding is completed, the lifting mechanism 5 is operated to move the upper mold 6 upward. The power bank is on the placing table 2. Then, the first driving mechanism is operated to lower the positioning plate 3 until the positioning plate 3 does not protrude from the top of the placing table 2 and then stop. During this process, under the action of the second driving mechanism, the pushing plate 4 starts to act when the positioning plate 3 does not protrude from the top of the placing table 2, so that the power bank is separated from the placing table 2. Compared with the prior art, after welding is completed, the positioning plate 3 automatically descends, and at the same time the pushing plate 4 smoothly pushes out the power bank, making it more convenient to take out.

[0028] As a preferred solution of the present utility model, the first driving mechanism includes a power mechanism 7 fixed inside the placing table 2. The output end of the power mechanism 7 is a moving block 8. A pushing shaft 9 is fixed to the moving block 8. The two positioning plates 3 are fixedly connected with a fixing plate 10, and an inclined hole 11 is opened on the fixing plate 10. The pushing shaft 9 passes through the inclined hole 11;

[0029] In this embodiment, the power mechanism 7 adopts a cylinder, an oil cylinder or an electric push rod, and the purpose is to make the moving block 8 and the pushing shaft 9 have a linear displacement, such as Figure 3As shown, there is an angle between the inclined hole 11 and the movement track of the push shaft 9. When it is necessary to lower the positioning plate 3, the power mechanism 7 is operated to move the push shaft 9 to the left. Under the push of the push shaft 9, the positioning plate 3 and the fixed plate 10 are lowered. Similarly, when the push shaft 9 moves in the reverse direction, the positioning plate 3 and the like move upward.

[0030] As a preferred embodiment of the present invention, the fixed plate 10 is in a gate shape, the moving block 8 is in the middle of the gate-shaped plate, there are two push shafts 9, and two inclined holes 11 are provided, as Figure 3 shown, to improve the operating stability of the power mechanism 7.

[0031] As a preferred embodiment of the present invention, the second driving mechanism includes a fixed shaft 12 fixedly connected to the positioning plate 3. The push plate 4 is fixedly connected with a connecting plate 13. The connecting plate 13 is provided with a guiding hole, and the guiding hole includes a connected vertical section 14 and an inclined section 15. The fixed shaft 12 passes through the guiding hole, as Figure 3 shown. When the positioning plate 3 protrudes from the placing table 2, the fixed shaft 12 passes through the vertical section 14 of the guiding hole, and the end of the inclined section 15 away from the vertical section 14 inclines downward. When the positioning plate 3 descends, the fixed shaft 12 first passes through the vertical section 14. At this time, the movement track of the fixed shaft 12 coincides with that at the vertical section 14, and it will not affect the positions such as the connecting plate 13. Then it passes through the inclined section 15. There is an angle between the inclined section 15 and the movement track of the fixed shaft 12, so that the connecting plate 13 and the push plate 4 slide to push the power bank away.

[0032] As a preferred embodiment of the present invention, the placing table 2 is fixedly connected with a track 16. The bottom of the push plate 4 is fixed with a slider 17, and the slider 17 is slidably connected with the track 16, as Figure 2 shown. The slider 17 is fixed at the middle position of the bottom of the push plate 4, and the connecting plate 13 is on both sides of the push plate 4, improving the stability of the push plate 4 when sliding.

[0033] As a preferred embodiment of the present invention, a feeding member 18 is arranged on the top of the base 1. The feeding member 18 and the push plate 4 are respectively on both sides of the placing table 2, as Figure 1 shown. The feeding member 18 includes an inclined part and a horizontal part. The power bank can slide when it is on the inclined part and stop at the horizontal part. The feeding member 18 can also be set as a conveyor belt, and the push plate 4 pushes the power bank onto the conveyor belt.

[0034] As a preferred embodiment of the present invention, the top of the positioning plate 3 is chamfered. The chamfer design makes it easier for the power bank to be placed between the two positioning plates 3.

[0035] As a preferred embodiment of the present utility model, the positioning plate 3 is in a gate shape, and the gate-shaped structure can fix the power bank simultaneously from both sides and the front and back directions, ensuring that the position of the power bank is more stable during the welding process and is not prone to displacement.

[0036] As a preferred embodiment of the present utility model, two openings 19 are provided on the side of the placement table 2, and the connecting plate 13 extends into the interior of the placement table 2 along the openings 19, which can reduce the space occupation.

[0037] As a preferred embodiment of the present utility model, a reinforcing plate 20 is provided between the connecting plate 13 and the push plate 4 to improve the stability between the connecting plate 13 and the push plate 4.

[0038] It should be understood that in the development process of any actual implementation, such as in any engineering or design project, a large number of specific implementation decisions can be made. Such development efforts may be complex and time-consuming, but for those ordinary technical personnel who benefit from this disclosure, without excessive experimentation, the development efforts will be a routine task of design, manufacturing, and production.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
