Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a welding device for pin soldering. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. Currently, batteries have a wide range of applications across many fields. The battery manufacturing process involves welding various structural components, such as the battery cover assembly and casing, the cover body and explosion-proof valve, and the terminals, all requiring corresponding welding equipment. While some welding is automated and performed directly on the production line, others, particularly in narrow areas or during the initial welding of certain parts, may require manual welding, resulting in lower welding efficiency.

[0003] For the pin welding of battery cover components, manual welding is often used. Operators place the pins into the corresponding welding fixtures and then operate the welding equipment to weld them. This method results in inconsistent welding quality, low welding efficiency, complex operation, and high cost. Moreover, the pins have unconventional and varied shapes, therefore, the welding equipment must meet multiple specification requirements.

[0004] In summary, there is an urgent need for a soldering device for pin soldering to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0039] This embodiment provides a welding device for pin soldering, which is used for rapid and precise soldering of pins to improve welding efficiency.

[0040] It should be noted that the component to be soldered 200 in this embodiment is a pin.

[0041] Please refer to Figures 1 to 4Specifically, the welding equipment for lead soldering includes a worktable 10, a welding turntable 20, and at least one welding device. The worktable 10 has at least one loading station for loading the workpiece 200, at least one unloading station for unloading the workpiece 200, and at least one welding station for welding the workpiece 200. The welding turntable 20 is rotatably connected to the worktable 10 and has multiple support sections 21 along its circumference, which support the workpiece 200. The welding turntable 20 can rotate to drive the multiple support sections 21 to circulate to the loading station, welding station, and unloading station for operation. The welding device is movably disposed at the welding station and is used to weld the workpiece 200 that has been transferred to the welding station.

[0042] The welding equipment for lead soldering in this embodiment, by setting a welding turntable 20 and rotating the welding turntable 20, allows each bearing part 21 to circulate between the loading station, the welding station, and the unloading station, thereby realizing the loading, welding, and unloading of leads without the need for manual welding, freeing up labor and improving welding efficiency. Furthermore, the movable setting of the welding device facilitates the welding of leads of various specifications, so that even if the welding position is different, the welding position can be adjusted by adjusting the position of the welding device, which has high adaptability.

[0043] Optionally, the number of bearing units 21 is not less than the number of workstations, so that each workstation can perform operations after the welding turntable 20 rotates to a position each time.

[0044] Preferably, the number of bearing sections 21 is greater than the number of workstations, so that multiple workpieces 200 to be welded can be loaded or unloaded at the same time, thereby further improving welding efficiency.

[0045] For example, in this embodiment, there are four support parts 21 and three workstations, which can improve welding efficiency.

[0046] Please refer to Figure 5 Furthermore, the workbench 10 is equipped with a position sensor 40, which is located at any of the multiple workstations. The position sensor 40 can detect the bearing part 21 that arrives at the workstation, so that each workstation can be sensed by the position sensor 40 during the operation, so that each workstation stops at the designated position with high accuracy, thereby realizing precise control of the rotation of the welding turntable 20.

[0047] Optionally, each support portion 21 is provided with a sensor 22 on its outer periphery. The sensor 22 can contact the position sensor 40, so that the position sensor 40 detects the sensor 22 and transmits a relevant signal to the control unit. The corresponding support portion 21 reaches the designated position to stop the rotation of the welding turntable 20.

[0048] Please refer to Figures 1 to 4 In this embodiment, each support portion 21 is detachably connected to a welding fixture 23, which has a mounting portion on which the workpiece 200 to be welded is mounted. The detachable connection between the welding fixture 23 and the support portion 21 allows the welding fixture 23 to be replaced with a matching welding fixture 23 after the specifications of the corresponding pins change, and the operation is convenient, thereby improving the adaptability of the welding equipment for pin welding.

[0049] Specifically, the mounting section has a mounting slot, and the pins are installed in the mounting slot with the soldering position facing upwards to enable the installation and soldering of the pins.

[0050] Furthermore, the welding turntable 20 is connected to a drive structure, which drives the welding turntable 20 to rotate, thereby realizing the rotation of the welding turntable 20.

[0051] Optionally, the worktable 10 is also provided with a fixing part, which is connected to the welding turntable 20 by a rotary bearing, thereby realizing the rotational connection between the welding turntable 20 and the worktable 10.

[0052] In this embodiment, the welding apparatus includes a fixed base 31 and a welding machine. The fixed base 31 is movably disposed at the welding station, and the welding machine is disposed on the fixed base 31. The position of the welding machine can be moved by means of the fixed base 31, thereby adjusting the welding position of the welding machine. This arrangement also enables position adjustment for both movable and immovable welding machines, thereby achieving adjustment of the welding position.

[0053] Specifically, the fixing seat 31 has multiple oblong holes 311 extending in a second direction along a first direction, with the second direction perpendicular to the first direction. The welding station has multiple threaded holes 11 along the first direction. Bolts pass through the oblong holes 311 and are threaded into the threaded holes 11 to fix the fixing seat 31 to the welding station. When position adjustment is required, the bolts are loosened, and the fixing seat 31 moves along the extension direction of the oblong holes 311 to achieve position adjustment of the welding device in the second direction.

[0054] Optionally, the number of threaded holes 11 is greater than the number of slotted holes 311, so that the position of the fixing seat 31 is adjustable along the first direction, thereby making the positions of the welding device in two mutually perpendicular horizontal directions adjustable. Through the automatic adjustment of the vertical direction by the welding machine, the position of the welding device in each direction is adjustable, thereby improving the adaptability of the welding equipment for lead welding.

[0055] Please refer to Figures 3 to 6In this embodiment, the welding equipment for pin welding also includes at least one positioning component 50. The positioning component 50 is set one-to-one with the welding station. The positioning component 50 can move in the vertical direction to press, position and release the workpiece 200 that has been transferred to the welding station, thereby realizing the positioning of the pin. This prevents the pin from moving during the welding process, improves the accuracy of pin welding, and thus improves the welding quality.

[0056] Specifically, the positioning component 50 includes a drive member 51 and a positioning fixture 52. The positioning fixture 52 is disposed at the output end of the drive member 51. The drive member 51 is used to drive the positioning fixture 52 to move in the vertical direction so that the positioning fixture 52 presses against or releases the workpiece 200 to be welded. This enables the positioning component 50 to press, position, and release the workpiece 200 to be welded, thereby facilitating the welding operation of the workpiece 200.

[0057] More specifically, the positioning fixture 52 is provided with welding holes 521, which are corresponding to the welding positions of the workpiece 200 to be welded, so that the welding positions of the workpiece 200 are exposed after the workpiece 200 is pressed, thereby enabling the welding device to weld the welding positions of the workpiece 200.

[0058] Furthermore, the positioning component 50 also includes a fixing structure 53, which is fixed to the welding device or the worktable 10. The driving component 51 is disposed on the fixing structure 53. The fixing structure 53 can fix the entire positioning component 50.

[0059] Furthermore, the positioning assembly 50 also includes a slider 54 and a guide rail 55. One of the positioning fixture 52 and the fixing structure 53 is provided with a guide rail 55, and the other is provided with a slider 54. The slider 54 is slidably connected to the guide rail 55, which can guide and restrict the movement direction of the positioning fixture 52. Specifically, the fixing structure 53 is provided with a guide rail 55, and the positioning fixture 52 is provided with a slider 54 to guide the movement of the positioning fixture 52.

[0060] Furthermore, the positioning component 50 also includes two limiting members 56, which are respectively disposed at the top and bottom of the positioning fixture 52 to limit and adjust the positioning fixture 52 in the vertical direction, thereby realizing the adjustment of the positioning position of the positioning fixture 52 on the workpiece 200 to be welded, thereby improving the adaptability of the welding equipment for pin welding.

[0061] Optionally, the limiting member 56 located at the bottom of the positioning fixture 52 can also serve as the sensing element 22 of the position sensor 40 to reduce the number of parts.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
