Description

Technical Field

[0001] This utility model relates to an antenna welding device, belonging to the field of communication module assembly technology. Background Technology

[0002] In the production process of NB-IoT (Narrowband Internet of Things) modules, antennas need to be assembled on communication substrates. During installation, antenna modules need to be soldered to ensure circuit connections. Since different soldering positions and angles require different positions, the actual soldering steps and requirements are quite complex. Therefore, traditionally, manual soldering is used to ensure that each solder point is soldered. However, due to the high cost of manual processing, it is difficult to control efficiency and yield. Therefore, there is an urgent need for an automated soldering device to achieve a fast soldering process for antenna modules. Summary of the Invention

[0027] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0030] This utility model provides an antenna welding device for automatically welding antenna modules onto the circuit board of a communication module. It can adapt to welding points at various angles, making the automatic welding process more reliable and optimizing cost and efficiency by replacing manual labor. To achieve the device's structural functions, it includes a base plate 1 and a rotating plate 4. A bearing seat 2 is mounted on the base plate 1, and a connecting shaft 3 is rotatably mounted within the bearing seat 2. The connecting shaft 3 is fixedly mounted to the rotating plate 4, meaning that the base plate 1 and the rotating plate 4 can rotate relative to each other through the connection of the connecting shaft 3. For welding narrowband IoT modules, a positioning mechanism is provided on the rotating plate 4. The positioning mechanism can be a positioning hole or other positioning component, capable of positioning the narrowband IoT module for placing the NB-IoT module to be soldered. To achieve basic soldering functionality, at least a soldering mechanism is required, including a soldering head 8 and a solder wire feed tube. The soldering head 8 and solder wire feed tube can be raised and lowered relative to the substrate 1 to allow the soldering components to move to the designated position for soldering. To avoid poor soldering or misalignment of the solder points with the soldering position, the device also includes a lifting component. Specifically, the lifting component includes a first drive device 6 and a connecting piece 7 rotatably disposed at the output end of the first drive device 6. Figure 1 as well as Figure 2 As shown, the connector 7 is fixedly connected to the rotating plate 4, so that the first driving device 6 can drive the rotating plate 4 to rotate relative to the substrate 1. When the rotating plate 4 rotates, its adaptation angle relative to the welding point of the welding mechanism will change, which is beneficial to place the molten solder point at the root of the antenna module, thereby achieving accurate welding and improving the yield of automated welding, thus realizing efficient welding operations instead of manual labor.

[0031] This utility model provides an antenna welding device. To enable the welding head 8 to provide multi-directional welding solutions, the welding mechanism further includes an adjustment plate 10 and a mounting bracket 9. Figure 9As shown, the solder wire feed tube and the welding head 8 are both fixed on the mounting bracket 9. An arc-shaped groove is provided on the adjusting plate 10, allowing the mounting bracket 9 to rotate within the arc-shaped groove around the welding point. This ensures that the welding angle is adjusted without shifting the position of the welding point. To ensure the stability of the adjusted position, a locking mechanism for positioning the mounting bracket 9 is also provided on the adjusting plate 10. This locking mechanism can be a corresponding angle control drive mechanism. In this case, the adjusting plate 10 functions only as a position guide plate. Figure 1 As shown, the adjusting plate 10 can be inclined at a certain angle to the axis of the connecting shaft 3, or preferably the relative inclination of the adjusting plate 10 can be adjusted, thereby improving the welding compatibility range.

[0032] This utility model provides an antenna welding device, which, in order to stabilize the welding position of a narrowband Internet of Things module, can provide two sets of baffles 11 on both sides of the substrate 1, such as... Figure 9 As shown, the stop block 11 is used to limit the rotation of the rotating plate 4 before it comes into contact with the substrate 1 during rotation, so as to avoid positional deviation between the actual welding point and the ideal welding point caused by unstable position control of the first driving device 6. That is, the contact position can be the welding position or the limit position of the rotation amplitude of the rotating plate 4. As a preferred embodiment, the top surface of the stop block 11 can be provided with an inclined surface that can match the inclination of the rotating plate 4 to ensure good contact effect of the contact surface, and magnetic attraction components are provided on the stop block 11 and the rotating plate 4, so as to maintain the accuracy of the relative position after the first driving device 6 (such as a cylinder or other component) is released (if the contact position is the welding position, the accuracy of the welding position is guaranteed).

[0033] This utility model provides an antenna welding device. Considering that it is most suitable to horizontally position the rotating plate 4 to facilitate the placement of narrowband IoT modules on the rotating plate 4, the device can be further configured to include a fixing plate 12 and a second driving device 5. The base plate 1 and the fixing plate 12 are slidably connected, that is, the fixing plate 12 is fixed in space, and the base plate 1 can actually slide in the horizontal direction through the sliding engagement. The second driving device 5 is used to drive the base plate 1 to move along the sliding direction of the base plate 1. It can be referred to as Figure 1 The connection method involves indirectly driving the connector 7 to move, thereby allowing the substrate 1 to slide in the horizontal direction. Furthermore, a guide post 13 is provided on the substrate 1, and a movable member 14, slidably mounted on the guide post 13, is fixedly provided on the fixed plate 12. Figure 8As shown, a first spring 15 is provided on the guide post 13 to abut against the movable member 14. The first spring 15 is used to move the substrate 1 closer to the fixed plate 12 so that the fixed plate 12 and the rotating plate 4 can be fitted and fixed at a specific angle position in the natural state. At this time, the second driving device 5 is used to drive the fitted state to separate, that is, to drive the substrate 1 to move away from the fixed plate 12. After moving away, it is rotated, so that the rotating plate 4 can be locked and positioned by the fixed plate 12 in the middle position, thereby ensuring the horizontality of the rotating plate 4 and realizing the positioning of the rotating plate 4 on the substrate 1 by the fixed plate 12.

[0034] This utility model provides an antenna welding device. To prevent positional instability of the narrowband IoT module during welding, the device further includes a holding component. Specifically, the holding component includes a guide sleeve 16 fixedly mounted on a rotating plate 4. Figure 4 as well as Figure 8 As shown, a guide rod 18 is slidably disposed inside the guide sleeve 16. A limiting plate 17 is connected to one end of the guide rod 18. Finally, a second spring 19 is also fitted on the guide rod 18 to cause the limiting plate 17 to be pressed against the surface of the rotating plate 4. The second spring 19 is used to provide elastic force to press the limiting plate 17 onto the narrow-band IoT module placed on the rotating plate 4, thereby ensuring the stability of the module during the welding process through elastic force.

[0035] This utility model provides an antenna welding device, such as... Figure 2 As shown, if the position of the limiting plate 17 itself cannot be avoided, the narrowband IoT module cannot be installed through the position of the limiting plate 17. In order to improve the flexibility of the limiting plate 17, the holding component is slidably set on the rotating plate 4. The placement position can be avoided by moving the limiting plate 17. If multiple narrowband IoT modules are to be welded at the same time, multiple sets of holding components can be set. Multiple holding components are connected to each other by connecting strips 20. The position of all limiting plates 17 can be avoided by moving the connecting strips 20 by a robot or manually. It should be noted that the height of the limiting plate 17 and the holding position need to meet the holding conditions.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
