Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to a welding fixture base. Background Art

[0002] With the continuous advancement of science and technology, people use mobile phones and other technological products more and more frequently. Among them, mobile phones and computer products are the most important tools. The above products need to use different connection interfaces and connection cables for wired connection; the connection cables are provided with connection interfaces at both ends, and different PCB boards are provided on the connection interfaces. The PCB board, whose Chinese name is printed circuit board, is also called printed circuit board. It is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. Because it is made by electronic printing, it is called a "printed" circuit board.

[0003] The PCB board needs to be welded together with the connecting cable for data transmission. During the operation, when the operator welds the cable to the PCB board, the operator usually directly places the PCB board and the cable on the operating table and welds them. This not only easily causes the PCB board to shift and affects the welding accuracy and welding efficiency, but also easily causes the cable to become tangled because it is directly placed on the welding operating table.

[0004] For example, a cable and PCB board welding jig disclosed in Chinese patent CN219536444U positions the PCB board by setting a PCB board placement groove. Of course, the size of the PCB board placement groove can be adjusted and set to different sizes to accommodate PCB boards of different specifications. During welding, the cable is fixed by a cable turnover jig, and the cable turnover jig and the cable fixed on the cable turnover jig are accurately positioned and fixed by setting a cable turnover jig placement groove, so that the cable corresponds to the soldering pad of the PCB board one by one, thereby improving the welding accuracy, efficiency and qualified rate.

[0005] However, there is no structure for treating the fume on the welding fixture, so that the harmful fume generated during the welding process cannot be treated, which will cause harm to nearby workers.

[0006] For this reason, we urgently need to provide a welding fixture base that can process smoke. Utility Model Content

[0007] The purpose of the utility model is to provide a welding jig base to solve the problem that the welding jig proposed in the above background technology has no structure for treating the fume, so that the harmful fume generated during the welding process cannot be treated, thereby causing harm to nearby workers.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a welding jig base, comprising a base and a fixed base, the fixed base being fixedly connected to the middle position of the inner bottom end of the base, the upper end of the base being connected to a welding mechanism, the welding mechanism comprising a purification unit and a fixed unit, the purification unit being arranged at the upper end of the base, and the fixed unit being arranged at the upper end of the base.

[0009] The purification unit includes a fan, a filter box, a connecting pipe, a blower, an air pipe, an air suction scoop, a first threaded rod, a cylinder, a fixing frame, a fixing plate, an activated carbon filter and a HEPA filter. The fan is fixedly connected to the right side of the upper rear end of the base, the filter box is arranged at the rear left end of the base, the connecting pipe is fixedly connected to the lower right end inside the filter box, the blower is fixedly connected to the right end of the connecting pipe, the air pipe is fixedly connected to the right end of the blower, the air suction scoop is fixedly connected to the right end of the air pipe, the first threaded rod is fixedly connected to the front side of the filter box, the cylinder is connected to the outside of the first threaded rod, the fixing frame is connected to the upper and lower ends inside the filter box, the fixing plate is fixedly connected to the front side of the fixing frame, the activated carbon filter is fixedly connected to the inner side of the fixing frame at the upper end inside the filter box, and the HEPA filter is fixedly connected to the inner side of the fixing frame at the lower end inside the filter box.

[0010] A further improvement is that mounting grooves are provided at the upper and lower ends of the front of the filter box, a circular hole is provided at the middle position of the left and right ends of the fixing plate, an internal thread is provided on the inner side of the cylinder, the first threaded rod is fixed to the front side of the filter box at the left and right ends of the mounting groove, the outer side of the first threaded rod is slidably connected to the inner side of the circular hole, the inner side of the cylinder is threadedly connected to the outer side of the first threaded rod, and the rear side of the cylinder is in contact with the left and right ends of the front side of the fixing plate. Thus, after the fixing plate is placed on the front side of the filter box and the circular hole passes through the first threaded rod, the cylinder is threadedly connected to the outer side of the first threaded rod until the rear side of the cylinder contacts the left and right ends of the front side of the fixing plate, so that the fixing plate can be fixed to the front side of the filter box.

[0011] A further improvement is that the outer side of the fixing frame is slidably connected to the inner side of the mounting groove, and the outer side of the fixing frame abuts against the inner side of the filter box. Thus, after the fixing plate is fixed to the front side of the filter box, the fixing frame will be fixed to the inner side of the filter box, so that the smoke entering the filter box will be filtered by the activated carbon filter and the HEPA filter before being discharged, thereby filtering and removing harmful substances in the smoke.

[0012] A further improvement is that the fixing unit includes a second threaded rod, a bearing, a clamping plate, a first handle, a support frame, a third threaded rod and a third handle, the second threaded rod is connected to the left and right ends of the inner rear of the base, the bearing is fixedly connected to the outer side of the second threaded rod at one end located in the base, the clamping plate is fixedly connected to the outer side of the bearing, the first handle is fixedly connected to the end of the second threaded rod away from the bearing, the support frame is fixedly connected to the upper side of the base above the fixed seat, the third threaded rod is connected to the inner upper end of the support frame, and the third handle is fixedly connected to the upper end of the third threaded rod.

[0013] A further improvement is that first threaded holes are provided at the left and right ends of the rear interior of the base, the outer side of the second threaded rod is threadedly connected to the inner side of the first threaded hole, and the lower side of the clamping plate is slidably connected to the rear interior bottom side of the base. Thus, when the first handle is rotated to drive the second threaded rod in the first threaded hole to rotate, the second threaded rod can be moved and the clamping plate can be driven to slide along the bottom side of the base.

[0014] A further improvement is that second threaded holes are opened at equal distances on the upper end of the inner part of the support frame, arc-shaped grooves are opened at equal distances on the upper end of the fixing seat, the outer side of the third threaded rod is threadedly connected to the inner side of the second threaded hole, the lower end of the third threaded rod abuts against the outer upper end of the cable, and the inner side of the arc-shaped groove abuts against the outer lower end of the cable.

[0015] A further improvement is that a rubber pad is fixedly connected to the outer side of the fixing frame, so that after the fixing frame is fixed to the inner side of the filter box, the rubber pad on the outer side of the fixing frame contacts the inner side of the filter box, thereby preventing the smoke entering the filter box from leaking out from the gap at the contact between the fixing frame and the inner side of the filter box without being filtered by the activated carbon filter and the HEPA filter.

[0016] In summary, the present application discloses a welding jig base.

[0017] According to the technical solution, during the welding process, by starting the fan and the blower, the smoke generated during welding can be blown to the left end by the fan, then sucked into the air pipe from the suction hopper, and then enters the filter box through the blower and the connecting pipe, and then filtered and purified by the activated carbon filter and the HEPA filter before being discharged, which plays a protective role for nearby workers.

[0018] Furthermore, when welding the PCB board and the cable, the PCB board is first placed between the clamping plates on the inner side of the base, and then the first handle is rotated to drive the second threaded rod to rotate while driving the clamping plates to move to the left and right ends of the PCB board to fix the PCB board. Then the cable is arranged in the arc groove, and then the third handle is rotated to drive the third threaded rod to rotate while moving down to the outer upper end of the contact cable to fix the cable. In this way, the PCB board and the cable can be fixed to the upper end of the base, ensuring the fixation of the PCB board and the cable during the welding process, thereby ensuring the accuracy of welding.
