Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] Example 1 like Figures 1 to 7 As shown, a welding clamping mechanism is provided. This clamping mechanism is installed on a welding operation platform to temporarily limit and fix the circuit board to be welded, preventing the circuit board from moving during welding and thus affecting the welding quality. The added clamping mechanism includes a circuit board welding clamping base 1 for installation on the welding operation platform. A welding support column 2 is bolted to the top center of the circuit board welding clamping base 1, which is used to support the circuit board to be welded. A first horizontal gripper 3 is movably disposed on one side of the welding support column 2, and the first horizontal gripper 3 is connected to one side of the circuit board welding clamping base 1 through a first movable mechanism. A vertical welding limiting plate 4 is disposed on the other side of the welding support column 2. The bottom end of the vertical welding limiting plate 4 is connected to the side of the circuit board welding clamping base 1 away from the first horizontal gripper 3. A first vertical limiting gripper 5 is movably disposed on one side of the vertical welding limiting plate 4, and a second vertical limiting gripper 6 is movably disposed on the other side of the vertical welding limiting plate 4.

[0013] In this embodiment, when it is necessary to solder the "horizontal surface" of the circuit board (equivalent to when the horizontal surface is convenient for soldering operation), the circuit board is placed "horizontally" on the top surface of the soldering support column 2, and then the first horizontal gripper 3 is "moved" by controlling and adjusting it to contact the top surface of the circuit board, thus limiting the circuit board on the top surface of the soldering support column 2. Then, the soldering operation is performed on the "horizontal surface" of the circuit board by the soldering equipment. When it is necessary to solder the "vertical surface" of the circuit board (equivalent to when the vertical surface is convenient for soldering operations), the circuit board is placed "vertically" on the side of the vertical soldering limiting plate 4. Then, by controlling and adjusting the "movement" of the first vertical limiting jaw 5 and the second vertical limiting jaw 6, the two ends of the circuit board are brought into contact, and the circuit board is limited on the side of the vertical soldering limiting plate 4. Then, the soldering operation is performed on the "vertical surface" of the circuit board by the soldering equipment.

[0014] Example 2 Based on Embodiment 1, the first movable mechanism of this configuration includes a first movable cylinder 31; the cylinder body of the first movable cylinder 31 is connected and fixed to the top end of the circuit board welding clamping base 1 through a fixed seat 32, and the output end rod of the first movable cylinder 31 is hinged to one end of the first horizontal gripper 3 through a hinge seat; the middle part of the first horizontal gripper 3 is connected to a connecting block through a hinge seat, and the connecting block is connected and fixed to the top end of the fixed seat 32 by bolts.

[0015] In this embodiment, by controlling the extension and retraction of the first movable cylinder 31, the first horizontal gripper 3 is driven to move under the hinge limit action of the hinge seat in the middle, so that the other end of the first horizontal gripper 3 "moves downward" and contacts one end of the top surface of the circuit board, thereby limiting and stabilizing the circuit board on the top surface of the welding support column 2.

[0016] Furthermore, a limiting structure is provided on one side of the welding support column 2 (relative to one side of the first horizontal gripper 3); the limiting structure includes a limiting baffle 71, which is movably configured. Movable connecting shafts 72 are connected to both sides of the end of the limiting baffle 71 away from the welding support column 2. The other ends of the movable connecting shafts 72 movably pass through the positioning plate 7 and are respectively connected to the connecting plate. The bottom end of the positioning plate 7 is fixed to the circuit board welding clamping base 1 by bolts. The bottom of the connecting plate is used to connect to the output rod of the electric push rod 73. The cylinder of the electric push rod 73 is fixed to the positioning plate 7 by bolts, and the electric push rod 73 drives the connecting plate to move relative to the positioning plate 7.

[0017] In this embodiment, by controlling the electric push rod 73 to move the connecting plate relative to the positioning plate 7, the connecting plate, through the movable connecting shaft 72 and under the "moving guidance" of the positioning plate 7, drives the limiting baffle 71 connected to the other end of the movable connecting shaft 72 to move. By controlling the limiting baffle 71 to move to a suitable distance from the top of one side of the circuit board, it can play a "limiting" role on the circuit board and prevent the side of the circuit board from moving (moving up and down, causing movement or displacement) during soldering.

[0018] Example 3 Furthermore, the end of the first vertical limiting gripper 5 away from the vertical welding limiting plate 4 is connected to the output rod of the first vertical movable cylinder 51 via a hinge seat. The cylinder body of the first vertical movable cylinder 51 is connected to the first vertical connecting seat 52 via bolts. The bottom end of the first vertical connecting seat 52 is connected to the circuit board welding clamping base 1 via bolts. The middle part of the first vertical limiting gripper 5 is connected to the first vertical connecting block via a hinge seat. The first vertical connecting block is connected and fixed to the side wall of the first vertical connecting seat 52 via bolts.

[0019] Meanwhile, the end of the second vertical limiting gripper 6 away from the first vertical limiting gripper 5 is connected to the output rod of the second vertical movable cylinder 61 via a hinge seat. The cylinder body of the second vertical movable cylinder 61 is connected to the second vertical connecting seat 62 via bolts. The bottom end of the second vertical connecting seat 62 is connected to the circuit board welding clamping base 1 via bolts. The middle part of the second vertical limiting gripper 6 is connected to the second vertical connecting block via a hinge seat. The second vertical connecting block is connected and fixed to the side wall of the second vertical connecting seat 62 via bolts.

[0020] In this embodiment, when the "vertical" direction is convenient for circuit board soldering, the circuit board to be soldered is placed "vertically" so that the other end of the circuit board contacts the side end of the vertical soldering limiting plate 4; then, by controlling the extension and retraction of the first vertical movable cylinder 51, the first vertical limiting gripper 5 is driven to move under the hinged limiting action of the hinge seat in the middle, so that the other end of the first vertical limiting gripper 5 "moves toward one end of the circuit board" and contacts one end of the circuit board, thus limiting the circuit board to one side of the soldering vertical soldering limiting plate 4; Then, by controlling the extension and retraction of the second vertical movable cylinder 61, the second vertical limiting gripper 6 is driven to move under the hinged limiting action of the hinge seat in the middle, so that the other end of the second vertical limiting gripper 6 "moves toward the other end face of the circuit board" and contacts the other end face of the circuit board, limiting the circuit board to the other side of the welding vertical welding limiting plate 4; thus, by controlling the "movement" of the first vertical limiting gripper 5 and the second vertical limiting gripper 6, the circuit board is limited to the side end face of the welding vertical welding limiting plate 4, preventing the circuit board from shifting during welding.
