[0027] Example 1: like Figure 1 As shown, this embodiment proposes a copper foil welding and fixing device, including: The accommodating structure 1 includes a base 11 and a welding table 12. The welding table 12 is disposed on the upper end of the base 11 and has a welding groove 121. And the rotating structure 2, including a fixed component and a rotating component, the fixed component is disposed on either side of the base 11, the rotating component is rotatably connected to the fixed component, and the rotating component is provided with a rotating plate 24, the rotating plate 24 is configured to abut against the welding groove 121; The base 11 is provided with a first limiting member, and the welding table 12 is provided with a second limiting member. The welding table 12 is limited on the base 11 by the first limiting member and the second limiting member.

[0028] Specifically, a base 11 and a welding table 12 are provided on the housing structure 1. The base 11 has a position for mounting the welding table 12. The base 11 and the welding table 12 can be integrally set. Preferably, the base 11 and the welding table 12 are detachably fixed to adapt to different structures and sizes of welding tables 12, thereby enabling the fixing device to adapt to copper foil welding of circuit boards of various sizes. The welding table 12 is provided with a welding groove 121, which is used to limit and fix the circuit board and copper foil to be welded, so that manual or automatic welding can be performed after fixing. In order to improve the stability of welding, a rotating plate 24 is usually provided. The rotating plate 24 abuts against or disengages from the welding groove 121 by rotating. By using the rotating structure 2, the abutment and pressing of the circuit board or the disengagement after welding can be achieved. The rotating plate 24 automatically presses against itself by its own weight, which not only makes the fixture simpler and more convenient, but also eliminates the need for alignment and simplifies the operation. Furthermore, the rotation control of the rotating plate 24 can be made more flexible by manual or automatic control.

[0029] Furthermore, the rotating plate 24 not only has the function of pressing, but also prevents solder paste from flowing to the other side of the rotating plate 24 during soldering, thereby reducing the risk of products being unsightly or having their performance affected due to frequent solder overflow or leakage during manual soldering, which may lead to scrap.

[0030] Meanwhile, a first limiting member is provided on the base 11, and a second limiting member is provided on the welding table 12. The welding table 12 and the base 11 can be fixed in the desired position by the two limiting members. The limiting member can be any of the following structures: a combination of screw holes and screws, a clamping structure, a limiting protrusion, magnetic attraction, etc., so as to fix the welding table 12 in the desired position on the base 11.

[0031] The copper foil welding fixing device includes a receiving structure 1, comprising a base 11 and a welding table 12, with the welding table 12 positioned on the upper end of the base 11 and having a welding groove 121; and a rotating structure 2, comprising a fixing component and a rotating component, with the fixing component positioned on either side of the base 11 and the rotating component rotatably connected to the fixing component, and the rotating component having a rotating plate 24 positioned to abut against the welding groove 121; wherein the base 11 is provided with a first limiting member and the welding table 12 is provided with a second limiting member, the welding table 12 being limited on the base 11 by the first and second limiting members. This allows the rotating plate 24 to be rotated and pressed into the welding groove 121, thereby achieving low cost and long lifespan of the device, and the first and second limiting members are used to adapt to the welding of copper foil on circuit boards of various sizes.

[0032] Example 2: Please refer to Figure 1 and combined with, for example Figures 2-4 As shown, this embodiment further explains and optimizes the structure in Embodiment 1, with the following differences: In some embodiments, the first limiting member is configured as at least one first positioning through hole 111, the welding table 12 is provided with a connecting through groove 122, and the second limiting member is configured to pass through the first positioning through hole 111 and the connecting through groove 122 for fixation.

[0033] Specifically, the first limiting member has multiple first positioning through holes 111, which can be configured as two rows of parallel first positioning through holes 111. This allows for the fixation of the welding table 12 and the base 11 through the two rows of first positioning through holes 111, resulting in more stable fixation. The welding table 12 is provided with a connecting through groove 122 to align the first positioning through holes 111 and the connecting through groove 122. A second limiting member, which can be a movable screw, allows the movable screw to extend into the first positioning through hole 111 and the connecting through groove 122 for tight locking and fixation. In some optional embodiments, the connecting through groove 122 can be a connecting through hole, allowing for alignment and fixation through the first positioning through hole 111 and the connecting through hole. The alignment and fixation method of the connecting through groove 122 is more flexible than that of a connecting through hole, and the welding table 12 with the connecting through groove 122 can accommodate a wider variety of sizes and dimensions.

[0034] In some embodiments, the connecting through groove 122 is connected to the welding groove 121, and the bottom of the welding groove 121 is provided with a first positioning through hole 111 so that the second limiting member is set to limit the inside of the welding groove 121.

[0035] Specifically, the connecting through slot 122 is connected to the connecting slot, and the second limiting member can be a movable screw, so that the movable screw can not only fix the welding station 12 and the base 11, but also further fix and limit the circuit board set inside the welding slot 121. For example, when the first positioning through hole 111 is located at the bottom between the connecting through slot 122 and the connecting slot, a certain opening can be provided in the connecting through slot 122 so that the movable screw can pass through the first positioning through hole 111 and be partially set in the connecting through slot 122. This method allows a circuit board smaller than the welding slot 121 to be set in the welding slot 121 for welding and improves the stability of the circuit board in the welding slot 121.

[0036] In some embodiments, the fixing component is provided with a rotating shaft 21 and a support portion 22. The support portion 22 is vertically disposed on the base 11, the rotating shaft 21 is disposed on the upper end of the support portion 22, the first side 241 of the rotating plate 24 is rotatably connected to the fixing component, and the second side 242 of the rotating plate 24 is configured to abut against the welding groove 121.

[0037] Specifically, the fixing component includes a rotating shaft 21 and support parts 22. There can be two support parts 22, allowing the rotating shaft 21 to rotate between them. The support parts 22 are vertically mounted on the base 11, increasing the height of the rotating shaft 21 and further raising the height of the first side surface 241 of the rotating plate 24 connected to the rotating shaft 21. This allows the second side surface 242 of the rotating plate 24 to fall naturally into the welding groove 121 under gravity. The connection between the first side surface 241 and the rotating shaft 21 can be achieved by providing a through groove in the first side surface 241, with the rotating shaft 21 positioned within this groove. The support parts 22 can have connecting holes (not shown) for mounting the rotating shaft 21, with both ends of the rotating shaft 21 mounted on the two support parts 22, allowing it to rotate within the connecting holes. The first side surface 241 and the rotating shaft 21 can be integrally formed or detachable.

[0038] The fixed component can achieve the function of pressing the circuit board through a simple structure, without the need to use a drive structure to drive the rotating plate 24, further simplifying the structure of the device and reducing the cost of the device.

[0039] In some embodiments, the fixing component is provided with a counterweight 23, which is rotatably mounted on the rotating shaft 21, and the first side 241 is connected to the counterweight 23.

[0040] Specifically, the counterweight 23 is mounted on the rotating shaft 21, and the rotating plate 24 is connected to the counterweight 23 via the first side 241, so that the weight of the first side 241 is greater than the weight of the second side 242, which makes the rotation of the rotating plate 24 more stable.

[0041] In some embodiments, the counterweight 23 is provided with a second positioning through hole 231, the rotating plate 24 is provided with a fixing hole 245, and the rotating plate 24 is provided with a third limiting member. The third limiting member passes through the fixing hole 245 and the second positioning through hole 231 and is configured to fix the counterweight 23 and the rotating plate 24.

[0042] Specifically, the counterweight 23 is provided with a second positioning through hole 231, which can be multiple and arranged from top to bottom. The rotating plate 24 is provided with a fixing hole 245, more specifically, a fixing hole 245 is provided on the first side 241. The third limiting member can be a movable screw, which can be fixed by passing through the second positioning through hole 231 and the fixing hole 245. Multiple second positioning through holes 231 allow for selection of different heights for fixing the first side 241. In some preferred embodiments, the second positioning through hole 231 is set as a positioning groove, which allows the second positioning through hole 231 and the fixing hole 245 to be locked by the movable screw after the height of the first side 241 is selected, thereby achieving the fixation and height adjustment of the movable plate and the counterweight 23. In this way, the height of the first side 241 can be adjusted, allowing the rotating plate 24 to be adapted to the use of welding stations 12 of more sizes and dimensions.

[0043] In some embodiments, a gripper 246 is provided on the rotating plate 24, and the gripper 246 is configured to lift the rotating plate 24 out of the welding groove 121.

[0044] Specifically, the grip 246 can be a handle, so that when welding on the welding station 12 is completed, it is convenient to manually rotate the rotating plate 24 from inside the welding groove 121 to outside the welding groove 121.

[0045] In some embodiments, the rotating plate 24 is provided with a first portion 243 and a second portion 244, the first portion 243 being rotatably connected to the fixed component, and the second portion 244 being abutting within the welding groove 121.

[0046] Specifically, the rotating plate 24 is provided with a first part 243 and a second part 244. The first part 243 is rotatably connected to the fixed component to achieve rotation around an axis, and the second part 244 is used to abut against the welding groove 121. The first part 243 and the second part 244 can be integrally set or detachably set, for example, by fixing the two parts by snap-fit, so as to facilitate partial replacement of the rotating plate 24. This structure allows for partial replacement of the rotating plate 24, and at the same time, the second part 244 can be replaced selectively so that the rotating plate 24 can abut against welding stations 12 of different specifications and sizes.

[0047] In some embodiments, the upper and / or lower surfaces of the second portion 244 are provided with arcuate surfaces 247 to reduce the area of ​​the second portion 244 abutting against the welding groove 121.

[0048] Specifically, the upper and / or lower surfaces of the second part 244 are provided with arc surfaces 247 so that the included angle between the upper and lower surfaces of the second part 244 is an acute angle, thereby reducing the area of ​​the second part 244 abutting against the welding groove 121. In this way, the effective contact area between the second part 244 of the rotating plate 24 and the circuit board is smaller, avoiding ineffective contact with the circuit board or copper foil during pressing, and further preventing the rotating plate 24 from scratching the circuit board and copper foil.

[0049] In some embodiments, the welding groove 121 is provided with a notch 1211, and the rotating plate 24 is disposed in the notch 1211 and abuts against the welding groove 121.

[0050] Specifically, the welding groove 121 is provided with a notch 1211 so that when the width of the rotating plate 24 is longer than that of the welding groove 121, the rotating plate 24 can abut against the welding groove 121 instead of being disposed on the welding groove 121.

[0051] The serial numbers of the utility model embodiments are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are only preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
