Description

Technical Field

[0001] The invention relates to the technical field of PCBA board welding, and in particular to a PCBA board welding device. Background Art

[0002] When workers are soldering components on the PCBA board, they need to use a soldering iron to process the tin wire so that the pins of the components are connected to the PCBA board under the action of the solder.

[0003] However, the soldering process releases a variety of harmful gases and fumes, including carbon dioxide, carbon monoxide, hydrogen, and various metal oxide particles. These pollutants can enter the human body through the respiratory tract, causing respiratory irritation, coughing, headaches and other symptoms. Long-term exposure may even lead to chronic lung diseases. Since the automated welding device can operate in a closed environment during the welding process, a series of filtering devices can be used to handle the harmful gases and fumes generated during welding during the automated welding process, so it will not affect the operator.

[0004] However, during manual welding, operators need to hold a soldering iron to weld the components on the PCBA board, so the PCBA board cannot be processed by operators in a closed environment. Therefore, for the operator's own safety, the simplest way is to wear a mask to prevent inhalation of harmful gases generated by welding.

[0005] However, in actual operation, the workers do not take the harmful gases produced by welding seriously, so the operators generally do not wear masks during welding and do not take any respiratory protection measures. Therefore, a welding device that can treat the harmful gases and smoke produced during manual soldering operations is needed to protect the operators and prevent them from inhaling harmful gases during manual welding. Summary of the invention

[0006] The purpose of the present invention is to provide a PCBA board welding device in order to solve the above problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

At this time, the bent rod and the stop block can be removed, and then the filter element can be taken out and replaced with a new one. The filter element replacement process is relatively convenient and simple, eliminating tedious steps and facilitating the staff to quickly get started and operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-6 , the present invention provides a technical solution:

[0033] PCBA board welding device, including:

[0034] An operating table 1, a fixing block 7 is fixed on the operating table 1, and a channel 8 is opened between the fixing block 7 and the operating table 1, and a suction fan 9 is installed in the channel 8;

[0035] A circular sleeve 10, a ring block 11 is fixed on the side wall of the circular sleeve 10, and the ring block 11 is connected to the channel 8 at one end of the fixed block 7 by a thread, a stopper 12 is fixed in the circular sleeve 10 to abut against the end of the filter element 14, and the other end of the filter element 14 abuts against the groove 16 opened on the side wall of the stopper 15, and a fixing piece for fixing the stopper 15 to the circular sleeve 10 is provided on the operating table 1;

[0036] The side wall of the circular sleeve 10 is provided with a plurality of circumferentially equiangularly distributed caulking grooves 13, and a caulking rod 17 adapted to the caulking grooves 13 is fixed on the annular block 11;

[0037] A through hole 2 is penetrated by a bottom rod 4 fixed at the bottom of the transparent plate 3, and the bottom rod 4 is connected to a screw sleeve 5 by threads to fix the transparent plate 3 to the operating table 1. A blower 6 is installed on the transparent plate 3, and the position of the blower 6 corresponds to that of the suction fan 9;

[0038] The screw rod 21 is rotatably connected to the operating table 1, and the screw rod 21 is connected to the clamp block 23 by a thread. The operating table 1 is provided with a slide groove 25, and a slider 24 slidably connected to the slide groove 25 is fixed on the clamp block 23. The clamp block 23 is provided with a vertical hole 26, and the soldering head of the soldering iron 28 is inserted into the vertical hole 26, and the soldering head abuts against the operating table 1. The part of the clamp block 23 that contacts the PCBA board protrudes with an elastic anti-skid pad. Therefore, the clamp block 23 can clamp and fix the PCBA board more stably.

[0039] The operating table 1 is provided with a corresponding groove 27 that matches the vertical hole 26, and the tip of the soldering iron 28 passes through the vertical hole 26 and extends into the corresponding groove 27, and the soldering iron 28 remains vertical at this time. With the cooperation of the vertical hole 26 and the corresponding groove 27, the soldering iron 28 is restricted, so that the soldering iron 28 can be placed at a specific position on the operating table 1, which is convenient for the staff to pick up.

[0040] The bent portion of the transparent plate 3 is made of a transparent material, and the PCBA board fixed by the two clamping blocks 23 can be directly observed through the bent portion of the transparent plate 3. The transparent plate 3 can protect the operator, so that even if smoke floats upward, it will be affected by the transparent plate 3, and will not float directly to the operator's face, and then be inhaled by the operator.

[0041] Specifically, Figure 1 and Figure 4 As shown, the fixing member includes a connecting block 18 fixed to the side wall of the stop block 15, and a bent rod 19 is fixed on the connecting block 18, a round hole 20 is opened at the end of the bent rod 19, and the bent rod 19 is slidably connected to the operating table 1, the operating table 1 is slidably connected to the round rod 30 on the Z-shaped rod 29, and the round rod 30 passes through the round hole 20, and the Z-shaped rod 29 cooperates with the positioning member to achieve the fixation of the stop block 15 and the round sleeve 10, and the positioning of the screw rod 21.

[0042] Specifically, Figure 5 As shown, the positioning member includes an opening 22 opened at the end of the screw rod 21, and the openings 22 are distributed at equal angles on the circumference of the end of the screw rod 21. A side rod 32 adapted to the opening 22 is fixed on the Z-shaped rod 29, and a spring 31 is sleeved on the round rod 30, and one end of the spring 31 abuts against the side wall of the Z-shaped rod 29, and the other end abuts against the corresponding protruding part of the operating table 1. Under the action of the positioning member, the screw rod 21 and the filter element 14 can be restricted together, so that the PCBA board remains stable after being fixed by the clamp block 23, and the filter element 14 can also play a subsequent effect of filtering solder smoke.

[0043] Specifically, Figure 5As shown, the operating table 1 is connected with a screw rod 33 by threading, and the operating table 1 is also provided with a transverse hole 34 that is slidably connected with the screw rod 33. The end of the screw rod 33 passes through the transverse hole 34 and abuts against the corner of the Z-shaped rod 29, and the side rod 32 at this time extends into the opening 22, and the round rod 30 passes through the corresponding position of the operating table 1 and extends into the round hole 20. Under the action of the screw rod 33, the Z-shaped rod 29 can be restricted, so that the Z-shaped rod 29 cannot be subjected to force and move laterally, and the Z-shaped rod 29 can only maintain its own position. At this time, the screw rod 21 and the filter element 14 can both stably play their respective roles, and there is no need to worry about accidentally touching the Z-shaped rod 29 to affect the screw rod 21 or the filter element 14.

[0044] In summary, when the soldering operation of components on the PCBA board is required in this embodiment, the soldering iron 28 is first pulled out from the corresponding groove 27 and the vertical hole 26, and set aside in a safe position for heating treatment. The screw rod 33 is rotated until the end of the screw rod 33 is retracted into the horizontal hole 34. The Z-shaped rod 29 is pushed to move, and the spring 31 is compressed until the side rod 32 on the Z-shaped rod 29 is separated from the opening 22 at the end of the screw rod 21. At this time, the end of the screw rod 21 can be rotated, so that the screw rod 21 is rotating, causing the clamping block 23 on the operating table 1 to clamp the PCBA board. Then, the thrust on the Z-shaped rod 29 can be released, and under the elastic force of the spring 31, the Z-shaped rod 29 moves until the side rod 32 extends into the corresponding opening 22 at this time, and the position of the screw rod 21 is fixed, and the screw rod 21 cannot be rotated under force. The screw rod 33 is rotated in the reverse direction so that the end of the screw rod 33 extends into the corner of the Z-shaped rod 29, so that the Z-shaped rod 29 cannot move left or right.

[0045] The bottom rod 4 at the bottom of the transparent plate 3 is passed through the through hole 2, and the transparent plate 3 and the operating table 1 are fixed as a whole using the screw sleeve 5. The PCBA board on the operating table 1 is soldered using the tin wire and the soldering iron 28. At this time, the blower 6 on the transparent plate 3 blows the smoke and toxic gas generated by the solder to the suction fan 9, and the suction fan 9 sucks the smoke and toxic gas into the filter element 14 for filtering. The toxic gas is directly discharged into the air after being filtered by the filter element 14. This protects personnel and prevents them from inhaling the toxic gas generated by the solder.

[0046] After soldering is completed, the screw rod 33 is rotated until the screw rod 33 is retracted into the horizontal hole 34. The Z-shaped rod 29 can be pushed to move until the side rod 32 is separated from the hole 22, and the screw rod 21 can be rotated until the clamping of the PCBA board is released.

[0047] When the filter element 14 is replaced regularly, the screw rod 33 is rotated until the screw rod 33 is retracted into the transverse hole 34. The Z-shaped rod 29 can be pushed to move until the side rod 32 is separated from the hole 22. The Z-shaped rod 29 is rotated so that the side rod 32 is not aligned with the end of the screw rod 21, and the lateral movement of the Z-shaped rod 29 is not blocked, and the Z-shaped rod 29 can be pulled to move until the round rod 30 on the Z-shaped rod 29 is separated from the round hole 20 on the bent rod 19. At this time, the bent rod 19 and the stop block 15 can be removed, and then the filter element 14 can be taken out, and then a new filter element 14 can be replaced, and then the filter element 14 can be fixed again at a specific position on the device with reference to the above-mentioned filter element 14 replacement process.

[0048] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
