DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0026] The embodiment of the present application provides a speed sensor PCB board welding equipment, which can solve the problem that the existing PCB board welding table in the related art often has a single function, only has a basic welding function, and lacks a smoke recycling device.

[0027] Please refer to Figures 1-3The application discloses a speed sensor PCB welding device, which comprises a table body 1, two welding stations 2 are oppositely arranged on the table body 1 and used for welding PCBs, a support 3 is arranged above the table body 1, a driving member 4 is arranged on the support 3, a recycling mechanism 5 is arranged on the driving member 4, and the driving member 4 is used for driving the recycling mechanism 5 to move along the width direction of the table body 1.

[0028] It should be noted that the two welding stations 2 are oppositely arranged on the device table body 1, and welding equipment (not shown in the figure) for welding PCBs or manual welding by workers is arranged on the side, away from the support 3, of each welding station 2.

[0029] The welding equipment generally comprises a welding head, a control system, a wire feeding mechanism, an operation interface and necessary adjusting mechanisms, which are prior art and will not be repeated here.

[0030] During the welding process, the PCB is placed on the welding station 2 and welded by the welding equipment; the driving member 4 installed on the support 3 is responsible for driving the recycling mechanism 5 to move along the width direction of the table body 1, so that the suction head 53 can accurately aim at the smoke generated above the welding station 2. The suction part 51 forms a negative pressure area at the suction head 53, and the suction head 53 attracts the smoke generated during the welding process.

[0031] Through the effective operation of the smoke recycling mechanism, the harm of smoke and harmful gas generated during the welding process to the working environment and the health of the operator is significantly reduced. At the same time, the timely recycling of the smoke also avoids the pollution and damage of the smoke to the welding equipment.

[0032] At the same time, the manual intervention and the time for cleaning the smoke are reduced, so that the production efficiency is improved. At the same time, the mobility of the recycling mechanism also facilitates flexible treatment of different welding stations.

[0033] Specifically, the welding station 2 in the embodiment comprises a sliding table 21 arranged on the table body 1, a sliding plate 22 arranged on the sliding table 21, the sliding plate 22 in a U shape, and a material placing plate 23 arranged above the sliding plate 22.

[0034] The table body 1 serves as a support foundation of the whole welding equipment, and is stably installed on the ground to provide reliable support for the welding station 2 and other components.

[0035] The sliding plate 22 can move smoothly along the length of the base 1 on the sliding base 21, so as to facilitate the adjustment of the position of the welding station 2 to adapt to the welding requirements of PCB boards of different sizes and shapes. The feeding plate 23 is arranged above the sliding plate 22 and is used to carry the PCB board to be welded.

[0036] During the welding process, the operator first places the PCB board to be welded on the feeding plate 23 and adjusts it to be aligned with the welding equipment such as a soldering gun or a soldering machine. Then, the operator can adjust the position of the welding station 2 by sliding the sliding plate 22 as needed, so as to perform the welding operation at the optimal angle and position.

[0037] Preferably, as shown in the drawings, Figure 4 In the embodiment, two pressing members 6 are arranged opposite to each other on the welding station 2. The pressing member 6 comprises a support column 61 arranged on the feeding plate 23, a rotating shaft 62 rotatably arranged on the support column 61, a coil spring arranged on the rotating shaft 62, and a pressing rod 63 arranged on the rotating shaft 62 and located outside the coil spring, and the other end of the pressing rod 63 extends obliquely downward.

[0038] The support column 61 serves as the support structure of the pressing member 6 and is arranged at both ends of the feeding plate 23 to ensure that the pressing rod 63 can accurately act on the specified position on the PCB board.

[0039] The rotating shaft 62 is rotatably arranged on the support column 61 and has the coil spring wound thereon. The design of the coil spring enables the pressing rod 63 to maintain a certain tension when not subjected to external force, thereby ensuring that a stable pressure is applied to the PCB board.

[0040] The pressing rod 63 is arranged on the rotating shaft 62 and located outside the coil spring. The other end of the pressing rod 63 extends obliquely downward to better fit the surface of the PCB board. The pressing rod 63 is made of rubber or plastic to ensure that the pressure applied to the PCB board is uniform and will not cause damage.

[0041] In one embodiment, the driving member 4 is a linear slide rail, and the adsorption part 51 is arranged on the sliding block of the linear slide rail.

[0042] The driving member 4 adopts a linear slide rail, which has the advantages of simple structure, easy maintenance, and high-precision linear motion control. The adsorption part 51 is directly arranged on the sliding block of the linear slide rail, and the precise recovery of the smoke above the welding station 2 is realized through the movement of the sliding block.

[0043] The linear slide rail has the advantages of high precision, high rigidity, and long service life, which can ensure the stability and accuracy of the adsorption part 51 during movement. At the same time, the maintenance cost of the linear slide rail is relatively low, and it is easy to realize automatic control.

[0044] In one embodiment, as shown in the drawings, Figure 3As shown, the adsorption unit 51 includes a housing 511 mounted on a slider of a linear slide rail. Inside the housing 511 are a fan 512 located above and a collection tank 513 located below. The air inlet of the fan 512 communicates with the collection tank 513, and the collection tank 513 contains several filters 514. Ventilation holes are provided on the housing 511, and the air outlet of the fan 512 is located at the ventilation holes of the housing 511.

[0045] The blower 512 is located above the housing 511, and its air inlet is connected to the collection tank 513. The negative pressure generated by the blower 512 is the driving force for the smoke and dust to enter the collection tank 513. By precisely controlling the speed and power of the blower, the efficiency of smoke and dust collection can be adjusted and optimized.

[0046] The collection tank is the main container for collecting smoke and dust. Several filters 514 inside effectively capture particulate matter and harmful substances in the smoke and dust, ensuring that the exhaust air meets environmental standards. Ventilation holes are provided on the housing 511, providing necessary exhaust channels for the fan 512.

[0047] When fumes are generated, the fan 512 starts working, creating negative pressure and drawing the fumes into the collection tank 513 through the air inlet. Inside the collection tank 513, the fumes are filtered by the filter screen 514, capturing harmful substances and particulate matter and retaining them inside the tank, while clean air is discharged through the air outlet of the fan 512 and the ventilation holes in the casing 511. As the welding process continues, fumes gradually accumulate in the collection tank. When a certain level is reached, welding work can be stopped, and the collection tank can be removed for cleaning and filter replacement.

[0048] Understandably, in order to facilitate cleaning of the collection tank 513 and replacement of the filter screen 514, both the shell 511 and one side of the collection tank 513 in this embodiment are open, and a cover plate fixed by bolts is provided at the opening, with the filter screen inserted inside the collection tank 513.

[0049] In this embodiment, several filter screens 514 may be one or more of PP filter screens, stainless steel filter screens, resin filter screens, nylon filter screens and polyester filter screens.

[0050] As a preferred embodiment, such as Figure 3 As shown, the connector 52 includes a support rod 521 disposed at the bottom of the housing 511, a support block 522 disposed on the support rod 521, and a slide bar 523 slidably disposed on the outer side of the support block 522. The slide bar 523 is elliptical in shape and bent downward at both ends. The slide bar 523 has sliding holes adapted to the support block 522. The adsorption head 53 is disposed on the slide bar 523.

[0051] The shape and size of the support block 522 are adapted to the sliding hole on the sliding bar 523. The function of the support block 522 is to provide a stable sliding track for the sliding bar 523, so that it can move smoothly along the support block 522.

[0052] The sliding bar 523 is elliptical in shape, with both ends curved downward, so that it has sufficient strength and stability and can also adapt to the needs of smoke dust recovery at different angles and positions.

[0053] During the smoke dust recovery process, the connecting piece 52 is connected to the shell 511 through the support rod 521 and allows the sliding bar 523 to slide and adjust on the support block 522. The operator can flexibly adjust the position and angle of the sliding bar 523 according to the position and diffusion of the smoke dust generated at the welding station 2, so that the adsorption head 53 can accurately aim at the source of smoke dust generation.

[0054] At the same time, the elliptical design and the structure of the two ends curved downward of the sliding bar 523 make it able to adapt to the needs of smoke dust recovery at different angles and positions, further improving the efficiency and accuracy of smoke dust recovery.

[0055] Specifically, the adsorption head 53 includes a flexible hose 531 and an air inlet hopper 532 connected to each other, the air inlet hopper 532 is located above the welding station 2, and the other end of the flexible hose 531 is in communication with the collection tank 513.

[0056] The flexible hose 531 is a flexible connection part of the adsorption head 53, one end of which is connected to the air inlet hopper 532, and the other end is in communication with the collection tank 513. The flexible hose 531 takes into account the characteristics and collection needs of smoke dust, ensuring that it has sufficient flexibility and sealing performance to adapt to the needs of smoke dust recovery at different angles and positions.

[0057] The air inlet hopper 532 is located above the welding station 2 and is the main collection port for smoke dust. The diffusion characteristics and collection efficiency of smoke dust during the welding process ensure that it can capture smoke dust to the maximum extent and guide it into the flexible hose 531. The shape and size of the air inlet hopper can be customized according to the specific situation of the welding station to improve the collection effect of smoke dust.

[0058] During the welding process, when smoke dust is generated, the air inlet hopper 532 will quickly capture these smoke dust and guide them into the flexible hose 531. The flexible hose 531 as a flexible connection part can adapt to the needs of smoke dust recovery at different angles and positions, ensuring that the smoke dust can smoothly enter the collection tank 513.
