[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] When implementing: Figure 1-5 As shown, a circuit board production welding machine that is easy to clean comprises: a processing box 1, a welding processing device 2 is fixedly connected to the inner wall of the processing box 1, a filter box 4 is fixedly connected to the upper end of the processing box 1, an exhaust pipe 3 is fixedly connected to one end of the filter box 4, one end of the exhaust pipe 3 is fixedly penetrated through the upper inner wall of the processing box 1 and extends into the processing box 1, a sealing cover 7 is slidably connected to the surface of the filter box 4, an air pump 5 is fixedly connected to the side end of the processing box 1, and the air pump 5 is connected to the inner wall of the filter box 4; a filtering mechanism 6 is used to increase the filtering effect in the filter box 4, and at the same time, the filtering mechanism 6 in the filter box 4 is conveniently replaced and cleaned, and is arranged in the filter box 4; a quick-installing mechanism 8, a quick-installing mechanism 8 for installing the sealing cover 7 is arranged on the upper side of the processing box 1; wherein the quick-installing mechanism 8 is provided with two groups, each group of the quick-installing mechanism 8 includes a connecting component 801 arranged on the upper side of the processing box 1, and a locking component 802 is arranged on one side of the connecting component 801. When the processing gas in the processing box 1 is filtered and discharged through the device When the air in the filter box 4 needs to be cleaned, the air pump 5 can be turned off. When the filter box 4 needs to be cleaned, the locking assembly 802 can be unlocked. The sealing cover 7 can be directly pulled to open the filter box 4. The filter box 4 can be cleaned at this time. When the cleaning and replacement are completed, the sealing cover 7 is reset and inserted back. The insertion of the sealing cover 7 will drive the connecting assembly 801 to rotate. When the sealing cover 7 is installed, the locking assembly 802 is manually locked to the connecting assembly 801. At this time, the sealing cover 7 completes the installation of the filter box 4 and seals it. At this time, the circuit board to be processed is placed on the surface of the welding processing device 2, and the welding processing device 2 is started to process the workpiece in the processing box 1 through the welding processing device 2. The welding processing device 2 includes a welding mechanism and a lifting mechanism. The structure of the welding processing device 2 and the air pump 5 is the same as the corresponding structure in the comparative document, so no further elaboration is given here.

[0025] like Figure 5As shown, the filtering mechanism 6 includes a connecting pipe 605 fixedly connected to the inner wall of one side of the filter box 4, the connecting pipe 605 is communicated with the exhaust pipe 3, the surface of the connecting pipe 605 is slidably connected with the filter cartridge 601, the inner wall of the sealing cover 7 is fixedly connected with a sealing plug 603, the sealing plug 603 is slidably connected to the inner wall of the filter cartridge 601, and a vent hole 604 is opened on the circumferential surface of the sealing plug 603. When the air pump 5 absorbs air, the air enters the filter box 4 through negative pressure. At this time, the air enters the inner wall of the filter cartridge 601. Because the other end of the filter cartridge 601 is blocked by the sealing plug 603, the air passes through the inner wall of the filter cartridge 601 to the surface of the filter cartridge 601 through negative pressure, and fully contacts the filter cartridge 601 for cleaning. After adsorption and filtration, it enters the air pump 5 through the air vent 604 and is discharged, which increases the filtering effect. When the sealing cover 7 is removed, the sealing plug 603 is separated from the filter cartridge 601, and the filter cartridge 601 is exposed. The filter cartridge 601 can be directly taken out for replacement, which is more convenient. The filter cartridge 601 has an inner and outer layer, respectively, of activated carbon and an adsorption layer, which can filter and adsorb harmful substances in the flowing air. The circumferential surface of the sealing plug 603 is fixedly connected with an extrusion plate 602, and the side end of the extrusion plate 602 is in contact with the filter cartridge 601. The extrusion plate 602 can be used to push the filter cartridge 601 to fit the inner wall of the filter box 4 for positioning, thereby preventing the filter cartridge 601 from shaking at will and separating from the connecting pipe 605.

[0026] like Figure 2 and Figure 3As shown, the connecting assembly 801 includes a first mounting block 8012 fixedly connected to the upper end of the processing box 1, the upper end of the first mounting block 8012 is rotatably connected to a gear 8014, the side end of the sealing cover 7 is fixedly connected to a rack 8011, the rack 8011 is meshed with the gear 8014, the side end of the rack 8011 away from the gear 8014 is slidably fitted with the surface of the filter box 4, when the sealing cover 7 is installed and inserted, it will drive the rack 8011 to move, and the rack 8011 drives the gear 8014 to rotate, the upper end of the processing box 1 is fixedly connected to a slide rail 8016, the lower end of the rack 8011 is fixedly connected to a slider 8017, the slide rail 8016 and the slider 8017 are slidably matched, and the side end of the first mounting block 8012 is fixedly connected to a guide frame 8015, the rack 8011 is slidably connected to the inner wall of the guide frame 8015. When the rack 8011 moves, it is easy to shake and tilt, and it is difficult to stably mesh with the gear 8014. At this time, when the rack 8011 slides, it drives the slider 8017 to slide on the inner wall of the slide rail 8016, so that the rack 8011 is more stable when sliding and is not easy to tilt. The guide frame 8015 can guide and position the sliding of the rack 8011, which is convenient for installation and alignment when the rack 8011 slides. The locking assembly 802 includes a hexagonal block 8021 fixedly connected to the surface of the rotating shaft 8013, and the side end of the first mounting block 8012 is fixedly connected to the second mounting block 8024, and the side end of the second mounting block 8024 is fixedly connected to the spring 8 023, one end of the spring 8023 is fixedly connected with a locking seat 8022, and the locking seat 8022 fits the surface of the hexagonal block 8021. When the sealing cover 7 is installed, the locking seat 8022 is pushed by the spring 8023 to fit the surface of the hexagonal block 8021. At this time, the hexagonal block 8021 will not rotate, the gear 8014 is not easy to rotate, and the sealing cover 7 cannot be pulled out. The inner wall of the second installation block 8024 is slidably connected with a "T"-shaped pull rod 8025, and the spring 8023 is sleeved on the circumferential surface of the "T"-shaped pull rod 8025. The locking seat 8022 can be easily pulled out of the hexagonal block 8021 and unlocked through the "T"-shaped pull rod 8025. At the same time, the spring 8023 pushes the locking seat 8022 and the hexagonal block 8021 to fix. When the spring 8023 is regularly moved, it is easy for the spring 8023 to be damaged due to lateral elastic deformation. At this time, the spring 8023 is supported by the "T"-shaped pull rod 8025, so that the spring 8023 is not easy to be lateral elastically deformed. The side end of the second mounting block 8024 is fixedly connected with a connecting block 8027, and the inner wall of the connecting block 8027 is slidably connected with a blocking fork 8026. When the sealing cover 7 is pulled to be disassembled, it is necessary to continuously pull the "T"-shaped pull rod 8025 to separate the locking seat 8022 from the hexagonal block 8021, which is rather troublesome. At this time, after the "T"-shaped pull rod 8025 is pulled, the blocking fork 8026 is slid to one side of the "T"-shaped pull rod 8025 to prevent the "T"-shaped pull rod 8025 from retreating. At this time, the sealing cover 7 can be directly pulled to unlock, which is more convenient.

[0027] When the utility model is in use, when the processing gas in the processing box 1 is filtered and discharged through the device, the air can be extracted through the air pump 5, and then the air in the processing box 1 is extracted through negative pressure, and the air enters the filter box 4 for filtering and discharge. When the operation is stopped, the air pump 5 is turned off. When it is necessary to clean the filter box 4, the "T"-shaped pull rod 8025 can be pulled. The "T"-shaped pull rod 8025 pulls the locking seat 8022 to disengage and unlock the hexagonal block 8021, and the blocking fork 8026 is slid to one side of the "T"-shaped pull rod 8025 to prevent the "T"-shaped pull rod 8025 from retreating. At this time, the sealing cover 7 is pulled, and the inner wall of the filter box 4 is exposed. At this time, the filter cartridge 601 is taken out. The filter box 4 can be cleaned. When the cleaning and replacement are completed, the filter cartridge 601 is inserted and the sealing cover 7 is reset and inserted back. The insertion of the sealing cover 7 will drive the rack 8011 to move, and the rack 8011 drives the gear 8014 to rotate, and then pull the blocking fork 8026, so that the spring 8023 pushes the locking seat 8022 to fit the surface of the hexagonal block 8021. At this time, the hexagonal block 8021 will not rotate, and the gear 8014 is not easy to rotate, and the sealing cover 7 cannot be pulled off. At this time, the sealing cover 7 completes the installation of the filter box 4 and seals it. At this time, the circuit board to be processed is placed on the surface of the welding processing device 2, and the welding processing device 2 is started to process the workpiece in the processing box 1 through the welding processing device 2.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
