Description

Technical Field

[0001] The present invention relates to the technical field of circuit board welding equipment, and in particular to a safe pressure welding process of a pressure welding protection mechanism. Background Art

[0002] With the development of society, people are using technological products more and more frequently. Electronics and computers are the primary tools used in these products. These products are all constructed from various types of circuit boards. Circuit boards primarily consist of pads, vias, mounting holes, wires, components, connectors, fillets, and electrical boundaries. Soldering a circuit board primarily involves connecting wires, components, and connector pins to corresponding metal vias using methods such as soldering to connect them to the circuit.

[0003] Currently, the technology for soldering wires to circuit boards usually uses a manual handheld or other heating device to heat the wire to melt the solder inside the wire, thereby soldering the wire and the board. These welding methods have many shortcomings. The temperature of heating devices such as soldering irons is not easy to control, which can easily damage the flexible cable or parts on the board.

[0004] Based on this, Chinese patent CN110508890A discloses a typical welding device, which includes a base, a top of the base is fixedly connected with a sliding plate, the top of the sliding plate is slidably connected with a sliding sleeve, the top of the sliding sleeve is installed with a fixed structure, the side of the top of the base is fixedly connected with two pillars, and the tops of the two pillars are fixedly connected by a cross bar. When in use, one end of the circuit board is inserted into the slot on the inner side of the fixed frame, and then the hand crank is rotated to fix the circuit board to prevent the circuit board from causing a cold solder joint at one end during welding. After welding on one side of the circuit board is completed, the crank is pulled to the right, and then the crank is rotated, and then the crank is released. At this time, the side of the circuit board that has been welded is suspended to avoid desoldering, which makes it convenient to weld the other side of the circuit board. This welding device can prevent the circuit board from having defects such as cold solder joints or desoldering, and is conducive to improving welding quality.

[0005] In addition, Chinese patent CN113333890A also discloses a PCB circuit board pre-soldering device, which includes a first base, a tin wire feeding assembly, a circuit board feeding assembly, a second base, a circuit board feed rail, a circuit board pushing assembly, a lifting seat assembly, a traction assembly, a wire pressing assembly and a welding assembly. The tin wire feeding assembly and the circuit board feeding assembly are both installed on the first base, the second base is arranged on the side of the first base, the circuit board feed rail is fixedly arranged on the second base, the circuit board feed rail is connected to the side of the circuit board feeding assembly, the lifting seat assembly is connected to the circuit board feed rail, the wire pressing assembly corresponds to the top of the circuit board feed rail, the traction assembly is installed on the second base, the traction assembly corresponds to the wire pressing assembly from the side, the circuit board pushing assembly connects the circuit board feeding assembly and the circuit board feed rail, the welding assembly is installed on the second base, and the welding assembly corresponds to the lifting seat assembly from top to bottom; this pre-soldering device has the advantages of simultaneous material loading and high welding efficiency.

[0006] However, in actual use, existing welding equipment often requires manual placement of materials into a pre-set loading fixture. This fixture then securely clamps and secures the materials before the welding mechanism begins welding. During this process, workers must manually adjust the placement of materials, and because the heating structure of the welding mechanism is often at high temperatures, workers are prone to burns during this process. Summary of the Invention

[0007] Based on this, it is necessary to provide a pressure welding protection mechanism to address the technical problem that safety accidents such as burns are prone to occur when placing materials during the welding process.

[0028] Please also refer to Figures 1 to 3 The present invention provides a pressure welding protection mechanism comprising: a base 1, a first actuating mechanism 2, a reversing track 3, and a second actuating mechanism 4. The first actuating mechanism 2 is disposed on the base 1 and comprises a first guide rail 201, a first movable portion 202, and a driving cylinder 203. The first guide rail 201 is fixedly connected to the base 1; the first movable portion 202 is movably connected along the first guide rail 201; and the driving cylinder 203 is in power connection with the first movable portion 202. The reversing track 3 is arranged above the first action mechanism 2; the reversing track 3 has a reversing connecting seat 301 and a reversing track part 302; the reversing connecting seat 301 passes through the first moving part 202 and is connected to the base 1; the reversing track part 302 is connected to the reversing connecting seat 301; the reversing track part 302 has a guide rail 302a, a deviation rail 302b and a return rail 302c; the guide rail 302a is arranged along the movement direction of the first moving part 202; the deviated rail 302b is respectively connected to the guide rail 302a and the return rail 302c; the deviated rail 302b is arranged along the direction of deviation from the first moving part 202; the guide directions of the return rail 302c and the guide rail 302a are parallel to each other. The second action mechanism 4 is respectively connected to the first action mechanism 2 and the reversing track 3; the second action mechanism 4 has a second guide rail 401 and a reversing moving part 402; the second guide rail 401 is arranged on the first moving part 202; the reversing moving part 402 has a reversing moving plate 402a, a pulley 402b and a welding tool 402c; the reversing moving plate 402a is movably connected along the second guide rail 401; the pulley 402b is arranged on the reversing moving plate 402a, and the pulley 402b is limited along the guide rail 302a, the deviated track 302b and the return track 302c; the welding tool 402c is connected to the reversing moving plate 402a.

[0029] Specifically, when a pressure welding protection mechanism of the present invention is in the working process, the material to be welded is placed on the welding fixture 402c; thereafter, the driving cylinder 203 drives the first moving part 202 to move forward along the guide of the first guide rail 201. At this time, the pulley 402b is limited to move within the guide rail 401; so that the reversing moving plate 402a moves following the movement of the first moving part 202; at this time, the welding fixture 402c connected thereto also moves following the movement of the first moving part 202. When the first moving part 202 moves to the welding processing area, the pulley 402b also simultaneously enters the deviated track 302b from the guide track 302a; that is, the deviated track 302b is a structure preset according to the actual welding process requirements. Synchronously, when the pulley 402b enters the deviated track 302b, it drives the reversing movable plate 402a and causes it to move along the guidance of the second guide rail 401. At the same time, the welding fixture 402c follows the movement of the reversing movable plate 402a. If the first action mechanism 2 is in a lateral movement state at this time, the welding fixture 402c can be adjusted to a longitudinal movement state at this time. After the pulley 402b reaches the farthest end of the deviated track 302b, the external welding mechanism presses and positions the material placed on the welding fixture 402c and welds it. Then, the driving cylinder 203 continues to drive the first moving part 202 forward. At this time, the pulley 402b enters the return track 302c from the deviated track 302b, driving the reversing movable plate 402a to return to the direction of movement of the first moving part 202. In the above-mentioned processing process, the area requiring manual participation is the design range of the guide rail 302a and the return rail 302c; when processes such as pressing or high-temperature welding that are prone to safety problems are required, it is divided into the action range of the deviation rail 302b; thereby, safety accidents of operators can be effectively avoided and the protective safety performance of the welding process can be improved.

[0030] Furthermore, the first movable portion 202 is provided with a plurality of first movable sliders 202a; the plurality of first movable sliders 202a are distributed below the first movable portion 202; each first movable slider 202a is movably connected to the first guide rail 201. Specifically, the first movable sliders 202a provided below the first movable portion 202 facilitate the movement of the first motion mechanism 2.

[0031] Furthermore, the driving cylinder 203 is provided with a push rod 203a and a push block 203b; the push rod 203a is in power connection with the driving cylinder 203; the push block 203b is respectively connected to the push rod 203a and the first moving part 202. Specifically, the driving cylinder 203 drives the push block 203b through the push rod 203a, thereby driving the first moving part 202 to move.

[0032] Furthermore, the first movable portion 202 is further provided with a relief groove 202b; the reversing connection seat 301 is movably sleeved in the relief groove 202b. Specifically, the relief groove 202b facilitates the reversing track 3 to be stacked above the first movable portion 202, thereby making the action mechanism more compact.

[0033] Furthermore, the second motion mechanism 4 is further provided with a drag chain structure 403; the drag chain structure 403 is connected to the welding tool 402c on the side of the first guide rail 201. Specifically, in the case of reciprocating motion, the drag chain structure can provide traction and protection for the components of the first motion mechanism 2 and the second motion mechanism 4. Moreover, each section of the drag chain structure can be opened, facilitating installation and maintenance.

[0034] In summary, the present invention provides a pressure welding protection mechanism that is respectively provided with a base 1, a first action mechanism 2, a reversing track 3 and a second action mechanism 4; various mechanism components are respectively arranged on the base 1; the first action mechanism 2 transmits materials in a preset direction under the drive of a power mechanism; and the reversing track 3 connects the first action mechanism 2 and the second action mechanism 4 respectively; and the reversing track 3 can synchronously make the second action mechanism 4 follow the action of the first action mechanism 2 when the first action mechanism 2 performs an action, or make the second action mechanism 4 act in a direction different from the first action mechanism 2; and place the material to be processed on the second action mechanism 4; so that the workstations that are prone to safety failures are effectively isolated by the second action mechanism 4 according to different action areas. Therefore, the present invention provides a pressure welding protection mechanism that solves the technical problem of the prior art that safety accidents such as burns are prone to occur when placing materials during welding.
