Description

Technical Field

[0001] This utility model relates to the field of electronic processing technology, and in particular to a high-speed soldering tool for precision circuit board surface mount technology. Background Technology

[0002] PCB surface mount soldering is a widely used technology in the electronics manufacturing industry. PCBs are the basic carriers of electronic devices. Surface mount technology involves accurately placing various tiny electronic components, such as chips, resistors, and capacitors, onto specific positions on the PCB. Soldering uses soldering materials, such as solder paste, and heat to firmly connect the leads of these surface mount components to the pads on the PCB, forming an electrical path.

[0003] A search revealed that the document with publication number "CN222547706U" mentions "this utility model discloses a flexible circuit board welding auxiliary tool, relating to the field of flexible circuit board processing, including a processing table, a shell fixedly connected to the top of the processing table, a motor fixedly connected to the outer wall of the shell, a rotating rod fixedly connected to the output shaft of the motor via a coupling, a gear fixedly connected to the outer wall of the rotating rod, a toothed plate movably connected inside the shell, a receiving plate fixedly connected to one side of the toothed plate, and a clamping plate fixedly connected inside the shell." In use, starting the motor causes the rotating rod to rotate, driving the gear to rotate. Through the meshing connection between the gear and the toothed plate, the toothed plate slides along the clamping plate, moving the receiving plate and causing the pressure plate to move above the flexible circuit board. Rotating the bolt causes the bolt to press against the pressure plate, causing the sleeve rod to slide along the L-shaped plate, thus pressing the pressure plate against the flexible circuit board and achieving the effect of pressing and limiting flexible circuit boards of different thicknesses.

[0004] However, in the existing electronics manufacturing industry, soldering is a critical step, especially in the production of precision circuit boards. Traditional soldering methods usually rely on manual operation or semi-automatic soldering machines. Such methods are prone to problems of unstable soldering accuracy and low efficiency when dealing with different types of circuit boards.

[0005] Therefore, we provide high-speed soldering tools for precision circuit board surface mount technology (SMT) to solve the above problems. Utility Model Content

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model utilizes a high-speed welding assembly. When needed, the exhaust gas extractor draws in the exhaust gas generated during the soldering process through the suction port, reducing the diffusion of soldering exhaust gas in the working environment. The longitudinal electric screw drives the longitudinal slide bar to move longitudinally, while the other end of the longitudinal slide bar is supported by a driven support rod.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a high-speed welding tool for precision circuit board surface mount, including a welding base 1, a high-speed welding assembly 2 on the outer side of the welding base 1, the high-speed welding assembly 2 including an exhaust gas suction machine 201 installed on the upper side of the welding base 1, side supports 202 welded on both the left and right sides of the welding base 1, guide frames 203 welded to the top of each side support 202, a longitudinal electric screw 204 installed on the inner side of the left guide frame 203, a driven support rod 205 welded on the inner side of the right guide frame 203, a longitudinal slide rod 206 connected between the longitudinal electric screw 204 and the driven support rod 205, a transverse bracket 207 welded to the lower side of the longitudinal slide rod 206, a transverse electric screw 208 installed on the lower side of the transverse bracket 207, and a transverse slider 209 passing through the middle of the transverse electric screw 208.

[0033] Furthermore, the exhaust gas extractor 201 is welded to the welding base 1. The exhaust gas extractor 201 is distributed in a C-shape on the upper periphery of the welding base 1. The suction port of the exhaust gas extractor 201 is tilted at 45 degrees. When needed, the exhaust gas extractor 201 will draw in the exhaust gas generated during the soldering process through the suction port to reduce the diffusion of soldering exhaust gas in the working environment.

[0034] Furthermore, the longitudinal electric lead screw 204 and the driven support rod 205 are parallel to each other. The longitudinal electric lead screw 204 and the driven support rod 205, together with the longitudinal slide rod 206, form a longitudinal sliding structure. When needed, the longitudinal electric lead screw 204 drives the longitudinal slide rod 206 to move longitudinally, while the other end of the longitudinal slide rod 206 is supported by the driven support rod 205. This allows for better control of the longitudinal movement position of the longitudinal slide rod 206 and improves accuracy.

[0035] Furthermore, the transverse electric lead screw 208 and the transverse slider 209 are connected by a thread, and the top of the transverse slider 209 is connected to the transverse support 207 by a slot. The transverse electric lead screw 208 and the transverse support 207, together with the transverse slider 209, form a transverse sliding structure. When needed, the transverse electric lead screw 208 drives the transverse slider 209 to move laterally, while the transverse slider 209 remains stable with the transverse support 207 through the slot, ensuring the stability and accuracy of the welding process. This reduces the error caused by transverse movement when welding within a small range, thus improving the welding quality.

[0036] Furthermore, an electro-hydraulic rod 210 is welded to the lower side of the transverse slider 209, and a temperature controller 211 is welded to the end of the electro-hydraulic rod 210. A welding needle 212 is connected to the lower side of the temperature controller 211. When needed, the electro-hydraulic rod 210 drives the temperature controller 211 and the welding needle 212 to rise and fall. This allows the welding height to be automatically adjusted by an external computer, achieving precise temperature control and accurate positioning of the welding point, ensuring the efficiency and quality of the welding process.

[0037] Furthermore, a laser pointer 213 is welded to the outside of the temperature controller 211, and a high-definition optical camera 214 is installed on the upper side of the laser pointer 213. The laser pointer 213 and the high-definition optical camera 214 are electrically connected. The endpoint of the laser pointer 213 indicates the welding point of the welding needle 212. When needed, the laser pointer 213 always points to the welding point of the welding needle 212. In this way, the high-definition optical camera 214 can more easily and accurately capture the welding process and welding position, ensuring welding quality.

[0038] Furthermore, the inner slot of the welding base 1 is connected to the circuit board mounting plate 3, and the inner slot of the circuit board mounting plate 3 is connected to the circuit board body 4. When it is needed, since the sizes of different models of circuit boards are not the same, the corresponding circuit board mounting plate 3 is selected according to the size of the circuit board body 4, and then the circuit board mounting plate 3 is inserted into the welding base 1. This can avoid welding defects caused by inaccurate installation position of the circuit board body 4.

[0039] Working principle: When needed, first place the welding base 1 in the required position, then place the circuit board mounting tray 3 containing the circuit board body 4 into the welding base 1. After placement, transmit the corresponding circuit data to the external computer device. At this time, the external computer device will control the longitudinal electric screw 204 in the guide frame 203 at the top of the side support 202 to rotate, thereby driving the longitudinal slide rod 206 to rotate along the direction of the longitudinal electric screw 204 and the driven support rod 205, thus controlling the longitudinal movement of the welding equipment as a whole. After reaching the longitudinal coordinate position, the external computer device... Next, the horizontal electric lead screw 208 under the horizontal support 207 is rotated, driving the horizontal slider 209 to the designated position. Then, the electro-hydraulic rod 210 is controlled to drive the welding needle 212 under the temperature controller 211 to perform welding. During this process, the laser positioner 213 always aims at the welding position of the welding needle 212, so as to facilitate the position capture and positioning of the high-definition optical camera 214 and realize real-time monitoring of the welding process. Finally, the fumes generated during the welding process are extracted by the exhaust gas extractor 201 to avoid air pollution. This completes the use of the precision circuit board surface mount high-speed welding tool.
