Description

Technical Field

[0001] This utility model belongs to the field of flat plate welding technology, and specifically relates to a flat plate welding device. Background Technology

[0002] Tablet computers, also known as portable computers, are small, portable personal computers that use a touchscreen as their primary input device. Manual assembly of tablet computers requires the use of a soldering iron for certain soldering tasks, such as soldering speaker wires and microphone wires.

[0003] There are various types of soldering iron tips on the market, the most common being round and flat tips. Because tablet computer circuit boards are relatively small, the weld seams between electronic components are also relatively small. Furthermore, since existing soldering irons can only be equipped with a single tip at a time, when a tablet computer requires soldering with different tips, multiple soldering irons with different tips must be used to complete the task. This increases the cost of purchasing soldering irons for manufacturers, and consequently, the assembly cost of the tablet computer.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a flat plate welding device.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a flat plate welding device that can solve the problem that an electric soldering iron can only be equipped with a single welding head and cannot meet the welding requirements.

[0007] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0008] A flat plate welding device includes: a handle and a rotating welding head mechanism;

[0009] The handle is fitted with a housing;

[0010] The rotary welding head mechanism is slidably disposed within the housing. The rotary welding head mechanism includes a mounting rod with a U-shaped groove. A rotating rod is rotatably connected within the U-shaped groove. Both ends of the rotating rod are threadedly connected to threaded seats, and a welding head is fixedly connected to the threaded seats. A pulling and fastening mechanism is connected to the side wall of the mounting rod, and the pulling and fastening mechanism corresponds to the rotating rod.

[0011] In one or more embodiments of this utility model, the side wall of the outer shell is provided with a fastening groove, and the pull fastening mechanism is movably disposed in the fastening groove. When the base slides in the fastening groove, the knob will be squeezed against the side wall of the outer shell under the action of the elastic rope, thereby fixing the rotating welding head mechanism inside the outer shell so as to use the welding head for welding.

[0012] In one or more embodiments of this utility model, the mounting rod, rotating rod, and threaded seat are all made of heat-conducting materials. When the rotating welding head mechanism is fixed inside the housing, the heat conductivity of the mounting rod, rotating rod, and threaded seat can be used to heat up the welding head so that welding can be performed using the welding head.

[0013] In one or more embodiments of this utility model, the pair of soldering heads are soldering heads of different shapes, such as flat soldering heads, conical soldering heads, or pointed heads, which makes it convenient for workers to use according to soldering needs. This not only enables the soldering iron to solder the joints between various compact electronic components and meet the different needs of tablet computer assembly soldering, but also reduces the purchase cost of the soldering iron and achieves the purpose of reducing assembly costs.

[0014] In one or more embodiments of this utility model, one end of the mounting rod located inside the housing is connected to a limiting post. The diameter of the limiting post is larger than the diameter of the mounting rod. The limiting post is used to limit the mounting rod, making it difficult for the mounting rod to completely slide out of the housing.

[0015] In one or more embodiments of this utility model, the pull-fastening mechanism includes a connecting seat, which is fixedly connected to the rotating rod and rotatably connected to the mounting rod. When the connecting seat rotates, it can drive the rotating rod to rotate.

[0016] In one or more embodiments of this utility model, an insertion post is slidably connected to one end of the connecting seat away from the rotating rod, and an insertion groove matching the insertion post is provided inside the connecting seat.

[0017] In one or more embodiments of this utility model, the depth of the insertion groove is greater than the length of the insertion post, the insertion post is a polygonal post, the insertion post can slide in the fastening groove, when the insertion post is inserted into the insertion groove, if the insertion post is rotated, the insertion post can drive the connecting seat to rotate, and then drive the rotating rod to rotate, so as to realize the switching of different welding heads.

[0018] In one or more embodiments of this utility model, a base is fixedly connected to the end of the insertion post away from the rotating rod, and the base is slidably disposed in the fastening groove. The base is used to connect the insertion post and the knob.

[0019] A knob is fixedly connected to the base, which not only makes it convenient for staff to rotate and insert the column, but also allows the rotating welding head mechanism to be fixed inside the housing by contacting the knob with the side wall of the housing, so that the welding head can be used to weld the tablet computer.

[0020] In one or more embodiments of this utility model, an elastic rope is connected to the inner wall of the insertion slot, and the other end of the elastic rope is connected to the insertion post. When the base slides into the fastening slot, the elastic rope is pulled and stretched, and exerts force on the insertion post and the knob, so that the elastic rope can be tightly attached to the side wall of the outer shell, thereby fixing the rotating welding head mechanism inside the outer shell, which facilitates subsequent welding work using the welding head.

[0021] Compared with the prior art, the flat plate welding device of this utility model can realize the switching of different welding heads. It can not only enable the soldering iron to weld the joints between various compact electronic components and meet the different needs of the assembly and welding of tablet computers, but also reduce the purchase cost of the soldering iron and achieve the purpose of reducing assembly costs.

[0030] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0031] like Figures 1 to 5 As shown, a flat plate welding device in one embodiment of the present invention includes a handle 1 and a rotating welding head mechanism 2.

[0032] The handle 1 has a control circuit inside, a cable connected to the handle 1 and electrically connected to the control circuit, a housing 101 installed on the handle 1, a soldering iron core connected to the control circuit inside the handle 1 installed inside the housing 101, and the end of the mounting rod 201 is in direct contact with the soldering iron core. The soldering head 204 heats up through heat conduction.

[0033] Additionally, the side wall of the outer casing 101 is provided with a fastening groove 102, and the pull-fastening mechanism is movably disposed within the fastening groove 102. When the base 208 slides along the fastening groove 102, the tension of the elastic rope 210 causes the knob 209 to come into close contact with the side wall of the outer casing 101, thereby fixing the rotating welding head mechanism 2 within the outer casing 101. When the control circuit is powered on, the soldering iron core heats the mounting rod 201, the rotating rod 202, and the threaded seat 203, causing the welding head 204 to heat up, allowing welding to be performed using the welding head 204.

[0034] like Figures 1 to 5 As shown, the rotary welding head mechanism 2 is slidably disposed inside the outer casing 101. A pair of welding heads 204 are installed on the rotary welding head mechanism 2, which is convenient for staff to use according to the welding requirements of the tablet computer, so as to meet the different needs of the tablet computer assembly welding, and at the same time reduce the purchase cost of the soldering iron, thereby achieving the purpose of reducing assembly costs.

[0035] The rotating welding head mechanism 2 includes a mounting rod 201 with a U-shaped groove, and a rotating rod 202 is rotatably connected within the U-shaped groove. The rotating rod 202 is used to mount a pair of welding heads 204, and can rotate 360° within the U-shaped groove to switch between the pair of welding heads 204.

[0036] In addition, both ends of the rotating rod 202 are threadedly connected to threaded seats 203, which are used to connect the welding head 204. At the same time, the welding head 204 can be replaced by connecting the threaded seats 203 to the rotating rod 202.

[0037] Preferably, the mounting rod 201, the rotating rod 202, and the threaded seat 203 are all made of heat-conducting materials. When the rotating welding head mechanism 2 is fixed inside the housing 101, the heat conductivity of the mounting rod 201, the rotating rod 202, and the threaded seat 203 can be used to heat up the welding head 204 so that welding can be performed using the welding head 204.

[0038] Specifically, a welding head 204 is fixedly connected to the threaded seat 203. The pair of welding heads 204 are welding heads of different shapes, such as flat welding heads, conical welding heads, or pointed heads, which makes it convenient for staff to use according to welding needs. This not only enables the soldering iron to weld the joints between various compact electronic components and meet the different needs of tablet computer assembly welding, but also reduces the purchase cost of the soldering iron and achieves the purpose of reducing assembly costs.

[0039] Meanwhile, since both welding heads 204 are mounted on the rotating rod 202, the preheating time of the welding heads 204 can be reduced when switching between them, which can improve work efficiency and reduce energy consumption to a certain extent.

[0040] like Figures 1 to 5 As shown, one end of the mounting rod 201 located inside the housing 101 is connected to a limiting post 205. The diameter of the limiting post 205 is larger than the diameter of the mounting rod 201. The limiting post 205 is used to limit the mounting rod 201, making it difficult for the mounting rod 201 to completely slide out of the housing 101.

[0041] like Figures 1 to 5 As shown, a pull-fastening mechanism is connected to the side wall of the mounting rod 201, which corresponds to the rotating rod 202. This mechanism is used to fix the rotating welding head mechanism 2 inside the housing 101 so that the welding head 204 can stably weld the tablet computer.

[0042] The tensioning and fastening mechanism includes a connecting seat 206, which is fixedly connected to the rotating rod 202 and rotatably connected to the mounting rod 201. When the connecting seat 206 rotates, it can drive the rotating rod 202 to rotate.

[0043] Additionally, an insertion post 207 is slidably connected to the end of the connecting seat 206 away from the rotating rod 202. The connecting seat 206 has an insertion groove that matches the insertion post 207. The depth of the insertion groove is greater than the length of the insertion post 207. The insertion post 207 is a polygonal post and can slidably reside within the fastening groove 102. When the insertion post 207 is inserted into the insertion groove, if the insertion post 207 rotates, it can drive the connecting seat 206 to rotate, which in turn can drive the rotating rod 202 to rotate, thereby enabling the switching of different welding heads 204.

[0044] Specifically, a base 208 is fixedly connected to the end of the insertion post 207 away from the rotating rod 202. The base 208 is slidably disposed in the fastening groove 102 and is used to connect the insertion post 207 and the knob 209.

[0045] like Figures 1 to 5 As shown, a knob 209 is fixedly connected to the base 208, which not only makes it convenient for the staff to rotate the insertion column 207, but also allows the rotating welding head mechanism 2 to be fixed inside the housing 101 by the contact between the knob 209 and the side wall of the housing 101, so that the welding head 204 can be used to weld the tablet computer.

[0046] An elastic rope 210 is connected to the inner wall of the insertion slot, and the other end of the elastic rope 210 is connected to the insertion post 207. When the base 208 slides into the fastening slot 102, the elastic rope 210 is pulled and stretched, exerting force on the insertion post 207 and the knob 209, so that the elastic rope 210 can be tightly attached to the side wall of the outer shell 101, thereby fixing the rotating welding head mechanism 2 inside the outer shell 101, which facilitates subsequent welding work using the welding head 204.

[0047] Preferably, the connector 206, the insertion post 207, the base 208, the knob 209, and the elastic rope 210 are all made of heat-insulating material, so that workers are less likely to be burned when rotating the knob 209.

[0048] In practical use, when switching between different welding heads 204, first disconnect the power, then pull the knob 209 to disengage it from the side wall of the housing 101. Use pliers or other tools to remove the mounting rod 201 from the housing 101. Release the knob 209, and the base 208 will contact the connecting seat 206 under the action of the elastic rope 210. When the rotating rod 202 is fully exposed from the housing 101, rotate the knob 209. The knob 209, through the base 208, the insertion post 207, and the connecting seat 206, will drive the rotating rod 202 to rotate within the U-shaped groove. Figure 4 The state shown.

[0049] After the rotating rod 202 has rotated 180°, the mounting rod 201 is reinserted into the housing 101. During the insertion of the mounting rod 201, the knob 209 is pulled to stretch the elastic rope 210. When the base 208 re-enters the fastening groove 102, the knob 209 is released. Under the action of the stretched elastic rope 210, the knob 209 makes tight contact with the side wall of the housing 101, thereby fixing the rotating welding head mechanism 2 inside the housing 101. The cable is then reconnected to power, and welding can be performed using the other welding head 204.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
