Description

[0001] The invention relates to the technical field of SMT patch technology, in particular to a single-track high-speed SMT patch line. Background Art

[0002] SMT patch refers to the abbreviation of a series of process flows based on PCB, and is the most popular technology and process in the electronic assembly industry. When assembling electrical components on a circuit board, it is necessary to adsorb and grab various electrical components to be assembled, and improve the efficiency of SMT patch through mechanical automation technology.

[0003] The existing Chinese patent with authorization announcement number CN115279061B discloses an SMT placement machine, including an actuator and a displacement device, wherein the actuator is provided with multiple groups and all are connected to the displacement device, and the actuator includes a mechanical clamping component: and also includes: a pneumatic clamping component connected to the mechanical clamping component; the pneumatic clamping component includes a Z-shaped connecting plate, a hydraulic cylinder is provided on one side of the Z-shaped connecting plate, the output shaft of the hydraulic cylinder is fixedly connected to the top of the Z-shaped connecting plate, and a sealing head is fixedly installed on the bottom of the other side of the Z-shaped connecting plate; the invention, by arranging the pneumatic clamping component and the mechanical clamping component to cooperate with each other, when clamping small electronic component patches, a gas adsorption method is simply used to clamp the electronic components, when clamping medium-sized electronic component patches, a mechanical clamping method is simply used to clamp the electronic components, and when clamping large electronic component patches, a gas and mechanical hybrid clamping method is used to clamp the electronic components, so as to solve the problem of low placement efficiency of existing SMT placement machines.

[0004] However, the SMT patch machine has the following defects when used:

[0005] 1. When existing SMT patch machines assemble various electrical components on the top of the circuit board, they need to adsorb and assemble various electrical components of various sizes. When operating, the traditional solution is generally equipped with two structures for adsorbing and assembling electrical components, which adsorb and fix smaller and larger electrical components respectively. However, when the above solution assembles smaller or larger electrical components, other electrical components adsorbed and fixed on the side will interfere with the normal patch assembly operation, making it inconvenient to perform patch assembly operations of various electrical components in the narrow space of the circuit board;

[0006] 2. When the existing SMT patch machine completes the patch assembly of the electrical components on the top of the circuit board, it needs to move the completed patch-assembled circuit board to the next step for curing and testing by means of mechanical arm grabbing and transportation or belt conveyor.

[0047] Compared with the prior art, one or more of the above technical solutions have the following beneficial effects:

[0048] 1. In a single-track high-speed SMT patch line, when adsorbing and fixing electrical components of different sizes, pneumatic suction cups can be used to fix smaller electrical components, and grab blocks can be used to fix larger electrical components, depending on the size of the electrical components. At the same time, when patching large or small electrical components, the third gear at the output end and the conveyor belt can be driven by a DC motor to operate. When patching larger electrical components, smaller electrical components can be automatically moved above them; when patching smaller electrical components, larger electrical components can be automatically moved above them, ensuring that electrical components can be patched in the narrow space of the circuit board during patch assembly. At the same time, when the above-mentioned patch operation is in progress, it will not cause collision or interference to the partial electrical components that have been patched, further ensuring the quality of the circuit board after the patch assembly is completed;

[0049] 2. In a single-track high-speed SMT patch line, when performing patch assembly operations on a circuit board for electrical components, it is necessary to drive the adsorbed and gripped fixed electrical components to move. At this time, start the drive motor to operate, driving the reciprocating screw and the horizontal sliding seat connected to its output end through the second transmission belt to operate, and drive the adsorbed and fixed electrical components to move horizontally, close to the position to be patched on the circuit board. When the reciprocating screw rotates to patch the electrical components, it can simultaneously drive the first gear, the second gear, the movable shaft, the second transmission belt and the cooling fan blades installed on its outside to operate, and automatically cool and shape the circuit board after the patch assembly, to ensure that the electrical components on the circuit board will not be offset or even fall off due to the vibration force generated by the transportation of the circuit board during the subsequent curing or testing of the circuit board after the patch is completed;

[0050] 3. In a single-track high-speed SMT patch line, when various electrical components are patched and assembled on a circuit board, the positions of the patch assembly of various electrical components are inconsistent. At this time, through the rotation of the reciprocating screw, the lifting and sliding of the vertical sliding seat on the side of the vertical slide rail, and the horizontal movement of the longitudinal sliding block driven by the threaded rod, the various electrical components that are adsorbed and fixed are driven to move in three-axis directions, ensuring that various electrical components can be close to the circuit board and moved to the corresponding patch assembly position of the circuit board, realizing automated electrical component patch assembly operations and improving the efficiency of circuit board patch assembly;

[0051] 4. In the single-track high-speed SMT patch line, the grabbing and patch assembly of different electrical components, and the cooling and shaping of the circuit board after the patch are all achieved through gear meshing connection. At this time, the design of gear meshing connection can improve the service life and stability of patch assembly and cooling and shaping, and improve the accuracy of electrical component patch assembly on the circuit board.

When the next group of circuit boards are to be patched and assembled with various electrical components, the horizontal sliding assembly 40 and the longitudinal sliding assembly 70 need to operate to move the adsorbed and fixed electrical components to the corresponding positions of the circuit boards. At this time, when the horizontal sliding assembly 40 is in operation, it will drive the cooling and shaping assembly 50 connected thereto to operate, and automatically perform cooling and shaping operations on the circuit boards that have completed the patch assembly, to ensure that when the circuit boards are subsequently cured and tested, the vibration force generated by the transportation of the circuit boards will not cause the assembled electrical components to shift or even fall off, thereby ensuring the quality of the circuit boards after the patching is completed.

[0090] Specific reference Fig.12The mechanical grabbing assembly 90 includes a metal shell 901, which is installed on the inner side of the mounting fixture 8064, and a driving motor 902 is installed on the outer side, and the output end of the driving motor 902 is connected to a transmission gear 903, wherein two groups of transmission gears 903 are provided, and the two groups of transmission gears 903 are meshed and connected, and the two groups of transmission gears 903 are rotatably connected to the inside of the metal shell 901; a connecting arm 904, which is installed at the bottom of the transmission gear 903, and a grabbing block 905 is rotatably connected on the outer side, and the grabbing block 905 is movably connected to the bottom of the metal shell 901, and electrical components are fixed to the side for grabbing.

[0091] In this embodiment, the inner side of the grab block 905 is rotatably connected with an oblique connecting rod 9051, which is arranged below the connecting arm 904 and extends to the outside of the grab block 905, wherein the bottom of the oblique connecting rod 9051 is rotatably connected with a protruding block 9052, which is installed on the side of the metal shell 901 and is arranged below the transmission gear 903. The rotatably connected oblique connecting rod 9051 can ensure that the movement of the grab block 905 is supported and guided when the grab block 905 is in operation, so that the grab block 905 can grab and fix electrical components.

[0092] In the single-track high-speed SMT patch line of the present invention, when patching a relatively large electrical component, the drive motor 902 is started to operate, so that a group of transmission gears 903 connected to its output end rotate, and another group of transmission gears 903 meshed and connected to the side of the transmission gear 903 can rotate (rotation direction is opposite). At this time, when the transmission gear 903 rotates, it will drive the connecting arm 904 installed at the bottom to operate, so that the grab block 905 rotatably connected to the bottom of the connecting arm 904 can move, and the electrical component can be grabbed and fixed.

[0093] Without limitation, any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent substitutions or changes according to the technical solution and inventive concept of the present invention, should be covered by the protection scope of the present invention.
