DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figures 1 to 6 In an embodiment of the present invention, a fixed mold for processing an integrated circuit board includes a fixed frame 1, a positioning tray 3, a carrier mold 4, a steering mechanism 6 and a screw linear module 7, characterized in that: a first servo motor 2 and a control unit 9 are fixed in the fixed frame 1, a rotating connecting plate 22 is fixed at the output end of the first servo motor 2, two positioning trays 3 are fixedly arranged on the top of the rotating connecting plate 22 in a mirror-symmetrical manner, the screw linear module 7 is fixed to the bottom of the positioning tray 3, the steering mechanism 6 is connected to the output end of the screw linear module 7, the steering mechanism 6 includes a second servo motor 62, the output end of the second servo motor 62 is fixedly provided with a lifting cylinder 64 through a cylinder connecting seat 63, the output end of the lifting cylinder 64 is fixedly provided with a steering connecting plate 61, the top of the positioning tray 3 is provided with an open groove 31 matching the outer contour of the steering connecting plate 61, and the carrier mold 4 is fixed to the top of the steering connecting plate 61.

[0023] Among them, the control unit 9 is a circuit board with a single-chip microcomputer as the core. The control unit 9 is electrically connected to the PLC control box of the circuit board processing equipment through wires. The first servo motor 2, the screw linear module 7, the second servo motor 62 and the control electromagnetic valve of the lifting cylinder 64 are all electrically connected to the control unit 9 through wires, which is convenient for the PLC control box of the circuit board processing equipment to jointly or directly control the control unit 9, so that the circuit board processing equipment and the various electrical units of the fixed mold for integrated circuit board processing can work in coordination; when the lifting cylinder 64 is in a retracted state, the lower end surface of the carrier mold 4 coincides with the top surface of the positioning tray 3, and the pressure of the contraction of the lifting cylinder 64 is utilized. The force makes the carrier mold 4 fit with the top surface of the positioning tray 3, so that the carrier mold 4 is not easily displaced or shaken during use, thereby improving the processing accuracy. A number of positioning grooves that match the outer contour of the circuit board 5 are evenly spaced on the top of the carrier mold 4, and the circuit board 5 is fixed in the positioning groove by the positioning column; the fixed frame 1 is fixed to the bottom of the operating platform of the circuit board processing equipment by screws, and a bearing seat 21 is provided between the output end of the first servo motor 2 and the operating platform of the circuit board processing equipment. The addition of the bearing seat 21 makes the output power output of the output shaft of the first servo motor 2 more stable and not easy to shake, reduces friction resistance, and improves the fit between the equipment.

[0024] The screw linear module 7 includes a screw 73, one end of which is connected to a third servo motor 74, and a nut seat 71 matching it is provided on the screw 73. The second servo motor 62 is fixedly connected to one side of the nut seat 71 through the connecting plate 8. The screw linear module 7 also includes a displacement sensor 72 for detecting the displacement distance of the nut seat 71. The third servo motor 74 and the displacement sensor 72 are both electrically connected to the control unit 9 through wires. The displacement sensor 72 can monitor the displacement of the carrier mold 4 along the screw 73 in real time, so as to facilitate the feedback of data to the control unit 9 for real-time adjustment. The output end of the lifting cylinder 64 is fixedly provided with a limit connection block 67 The limiting connecting block 67 is provided with two symmetrically arranged limiting guide rods 65 on the side opposite to the lifting cylinder 64. The cylinder body of the lifting cylinder 64 is provided with a sliding sleeve matching the limiting guide rod 65. The limiting connecting block 67 is fixedly connected to the steering connecting plate 61 by screws. The setting of the limiting guide rod 65 can effectively prevent the output shaft of the lifting cylinder 64 from rotating, further avoiding the shaking of the carrier mold 4 connected to the lifting cylinder 64, thereby improving the processing accuracy; the positioning tray 3 is a semicircular tray structure, and balancing weights 32 for balancing centrifugal force are fixed on both sides of the bottom of the positioning tray 3. The setting of the balancing weights 32 improves the stability of the positioning tray 3 during rotation.

[0025] The working principle of the present invention is as follows: through the positioning tray 3 on the two symmetrically arranged rotating connecting plates 22, and the board carrier mold 4 connected to the bottom of the positioning tray 3 by the screw linear module 7 and the steering mechanism 6, during operation, the positioning tray 3 on one side can be used as the processing area, and the positioning tray 3 on the other side can be used as the loading / unloading area. When the positioning tray 3 in the processing area completes the circuit board processing, the first servo motor 2 drives the positioning tray 3 to rotate 180 degrees. At this time, the positioning tray 3 in the processing area rotates to the loading / unloading area to perform the unloading and reloading operations, thereby realizing a reciprocating cycle operation, thereby improving the processing efficiency of the circuit board. At the same time, combined with the screw linear module 7 and the steering mechanism 6, the positioning tray 3 on one side can be used as the processing area, and the positioning tray 3 on the other side can be used as the loading / unloading area. The joint drive of the module 7 and the steering mechanism 6 can realize the translation and upward rotation of the carrier mold 4, and assist the micro-angle adjustment of the first servo motor 2. In actual use, it can cooperate with the circuit board processing equipment to realize multi-angle processing operations of electrical components. For example, in the welding operation of electrical components, the welding gun of the circuit board processing equipment can be kept fixed, and the solder joint welding process can be realized by the joint drive of the lead screw linear module 7 and the steering mechanism 6, or the carrier mold 4 can be rotated 180° relative to the positioning tray 3 to realize the steering operation of the circuit board 5. The blind angle of welding and other processing operations is small, which can effectively improve the processing quality of the circuit board. It has market prospects and is suitable for promotion.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
