Description

Technical Field

[0001] This utility model belongs to the field of welding technology, and in particular relates to a solder paste reheating device for PCB board mounting of automotive LED lights. Background Technology

[0002] Solder paste is a commonly used soldering material in the SMT industry. When using solder paste, it cannot be taken directly from the cooling room and used immediately. Instead, it must be left at room temperature for a period of time (2-4 hours) until the solder paste warms up to 25°C before it can be opened and used. Therefore, users usually place the solder paste on the rack after opening it to allow it to warm up naturally. However, this can cause impurities such as gold dust to fall into the solder paste container, resulting in contamination of the solder paste. A structure that can prevent the solder paste from being contaminated after opening is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a solder paste reheating device for PCB board mounting of automotive LED lights, thus solving the aforementioned problems.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a solder paste reheating device for PCB board mounting of automotive LED lights, including a frame and a protective component for preventing impurities from falling into the solder paste; the protective component includes a slide, shafts, fan blades and a cylinder, the slide is slidably connected in the frame, multiple shafts are rotatably connected in the slide, fan blades are fixedly connected to the multiple shafts respectively, the multiple fan blades are located at the center of the cylinder shaft, and the cylinder is fixedly connected to the frame.

[0005] Beneficial effects

[0006] This invention provides a solder paste reheating device for PCB board mounting of automotive LED lights, which has the following advantages compared with the prior art:

[0007] After opening the solder paste box, the technicians pressed it into the cylinder along the inclined surface of the clamping plate. This caused the clamping plate to slide into the groove of the cylinder, compressing the spring fixed to it. Throughout this process, the spring continuously provided a reaction force to the clamping plate, thus fixing the solder paste box in the cylinder. Simultaneously, the motor was started, causing the transmission gear to drive the guide rod fixedly connected to its shaft to rotate synchronously. This caused the main gear fixedly connected to the guide rod to rotate, which in turn drove the multiple auxiliary gears meshing with it to rotate synchronously. This caused the shaft fixedly connected to the shaft of the auxiliary gears to rotate, which in turn drove the fan fixedly connected to its top to rotate. The blades rotate synchronously, generating negative pressure airflow that is discharged from the top of the cylinder, preventing impurities from falling into the solder paste through the cylinder opening. Simultaneously, it accelerates the airflow within the cylinder, thus speeding up the solder paste's reheating. When the guide rod rotates, the worm gear fixedly connected to it begins to rotate, causing the worm gear to drive the worm wheel meshing with it. This, in turn, causes the worm wheel to drive the shaft fixedly connected to its axis to rotate synchronously, causing the gear fixedly connected to the shaft to rotate. This gear, in conjunction with the rack meshing with it, drives the slide table to move linearly, thereby adjusting the position of the solder paste within the cylinder. Attached Figure Description

[0021] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific main gear 207 described in the above embodiments. For example, the size of the main gear 207 should be larger than the size of the secondary gear 206. The purpose of this setting is to facilitate the adjustment of the transmission ratio through this setting.

[0022] Specifically, a guide rod 208 is fixedly connected to the shaft of the main gear 207, the guide rod 208 is rotatably connected to the slide table 201, and a partition plate 309 is hinged on the frame 101.

[0023] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific partition 309 described in the above embodiments. For example, the partition 309 is provided with a retaining ring, which can fix the partition 309 to the frame 101, so as to close the partition 309 in this way.

[0024] Specifically, a transmission gear 209 is fixedly connected to the guide rod 208, and the transmission gear 209 meshes with a gear fixedly mounted on the output shaft of the motor 301. The motor 301 is fixedly connected to the slide table 201.

[0025] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific motor 301 described in the above embodiments. For example, the motor 301 should be a motor with multiple adjustable speeds. The purpose of this setting is to facilitate the adjustment of the rotation speed of the fan blade 203 through this setting.

[0026] Specifically, a worm gear 302 is fixedly connected to the guide rod 208, the worm gear 302 is meshed with a worm wheel 303, and a rotating shaft 304 is fixedly connected to the axis of the worm wheel 303.

[0027] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific rotating shaft 304 described in the above embodiments. For example, the rotating shaft 304 is provided with bearing rings at both ends. The purpose of this arrangement is to reduce the friction on its rotation, thereby avoiding shaft breakage.

[0028] Specifically, the rotating shaft 304 is rotatably connected to the slide table 201, and a gear 305 is fixedly connected to one end of the rotating shaft 304. The gear 305 is meshed with the rack 306, and the rack 306 is fixedly connected in the frame 101.

[0029] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific frame 101 described in the above embodiments. For example, the bottom of the frame 101 should be provided with casters. The purpose of this arrangement is to facilitate the movement of the device through this arrangement.

[0030] Specifically, multiple clamping plates 307 are slidably connected to the cylinder 204, and a spring 308 is wound around the guide rod on the cylinder 204. One end of the spring 308 is fixedly connected to the cylinder 204, and the other end of the spring 308 is fixedly connected to the clamping plate 307.

[0031] Regarding the above examples, those skilled in the art should understand that the implementation of the above technical solutions is not limited to the specific spring 308 described in the above embodiments. For example, the spring 308 may be selected from other forms of elastic components. The purpose of this arrangement is that springs are prone to deformation after long-term use, and by replacing them with materials that are not easily deformed, the service life can be effectively extended.

[0032] In this embodiment of the utility model, after the solder paste box is opened, the relevant technicians press it into the cylinder 204 along the inclined surface of the clamping plate 307, so that the clamping plate 307 begins to slide into the groove of the cylinder 204 and begins to compress the spring 308 fixedly connected to it. During this process, the spring 308 always provides a reaction force to the clamping plate 307, thereby fixing the solder paste box in the cylinder 204. At the same time, the motor 301 is started, so that the transmission gear 209 drives the guide rod 208 fixedly connected to its shaft to rotate synchronously, so that the main gear 207 fixedly connected to the guide rod 208 begins to rotate, so that the main gear 207 drives the multiple auxiliary gears 206 meshing with it to rotate synchronously, so that the shaft 202 fixedly connected to the shaft of the auxiliary gear 206 begins to rotate, so that the shaft 202 drives its top The fan blades 203, which are fixedly connected to the cylinder 204, rotate synchronously, generating a negative pressure airflow that is discharged from the top of the cylinder 204. This prevents impurities from falling into the solder paste through the opening of the cylinder 204 and accelerates the heat recovery of the solder paste by speeding up the airflow inside the cylinder 204. When the guide rod 208 rotates, the worm gear 302 fixedly connected to it starts to rotate, which in turn drives the worm wheel 303, which in turn drives the rotating shaft 304 fixedly connected to its axis to rotate synchronously. This causes the gear 305 fixedly connected to the rotating shaft 304 to rotate, which in turn drives the slide table 201 to move linearly under the cooperation of the rack 306 meshing with it, thereby adjusting the position of the solder paste inside the cylinder 204.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0035] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0036] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused.
