Description

Technical Field

[0001] The invention belongs to the field of patch technology, and in particular relates to a camera SMT patch device. Background Art

[0002] Chip mounter: Also known as "mounting machine" or "surface mount system" (Surface Mount System). In the production line, it is configured after the dispensing machine or screen printer. It is a device that accurately places surface mount components on the PCB pads by moving the mounting head. The chip mounter moves the mounting head (with multiple vacuum suction nozzles) back and forth between the feeder and the substrate, takes the components out of the feeder, adjusts the position and direction of the components, and then places them on the substrate. Since the mounting head is installed on the arch-type X / Y coordinate moving beam, the arch-type chip mounter adjusts the position and direction of the components.

[0003] The placement head moves to the top of the feeder, takes the component from the component belt on the feeder, and then moves to the top of the substrate for placement. The displacement action time is long and the placement time is short, resulting in the placement time generally being consumed in the displacement and material picking process. The placement machine generally uses 3 suction nozzles that can be changed according to needs, so that the more frequent the reciprocating movement to pick up the material, the longer the time consumed by the placement head displacement.

[0030] Among them, the patch head 1 is used to absorb patch components and apply the components to the PCB substrate. The patch head 1 is a prior art and will not be described in detail here; specifically, the feeding mechanism 3 drives the screw rod to rotate through a motor to move it, so that the components that need to be absorbed in the feeding mechanism 3 move to the bottom of the patch head 1.

[0031] The feeding mechanism 3 includes a slide 31, a positioning power device 32, a displacement power device 33, a fixed plate 34 and a feeding device 4. The slide 31 is slidably connected to the beam 2, and several feeding devices 4 are slidably connected to the fixed plate 34. The fixed plate 34 is fixed on the slide 31. The positioning power device 32 and the displacement power device 33 are installed on the slide 31 and are transmission-connected to the feeding device 4.

[0032] Specifically, the positioning power device 32 is used to drive the feeding device 4 to move horizontally so that one end of the feeding device 4 moves to the bottom of the patch head 1, so that the patch head 1 can adsorb the patch component; after the feeding device 4 moves, the displacement power device 33 contacts the feeding device 4 and provides power to it at the same time, so that the patch component on it moves to switch to the next patch component for adsorption by the patch head 1.

[0033] Furthermore, the present invention also includes a robotic arm and a placement machine suction nozzle arranged on the robotic arm. The robotic arm drives the placement machine suction nozzle to absorb the patch components in the component belt on the feeder, and adsorbs the patch components and places them neatly in the jig box. When the feeding mechanism 3 returns to the origin position to load materials, the robotic arm adsorbs the neatly placed patch components in the jig box and transports them to the feeding mechanism 3. It can be equipped with multiple placement machine suction nozzles to ensure that multiple patch components are transported at one time to complete the loading action.

[0034] In another embodiment of the present invention, the feeding device 4 includes a skateboard 41, an auxiliary wheel 42, a power cut-off device 43, a positioning tooth 45, a conveyor belt 46 and a positioning fixture. The skateboard 41 is provided with a strip displacement slide hole 44 for the fixed plate 34 to pass through. The skateboard 41 is slidably connected to the fixed plate 34. Several auxiliary wheels 42 are installed on the skateboard 41. The power cut-off device 43 is installed on the skateboard 41 and cooperates with the displacement power device 33. The several auxiliary wheels 42 and the power cut-off device 43 are connected through a conveyor belt 46. The positioning teeth 45 are arranged on the skateboard 41 and are transmission-connected to the positioning power device 32; several positioning fixtures are equidistantly arranged on the conveyor belt 46 and are used for conveying and positioning patch components.

[0035] Specifically, a plurality of auxiliary wheels 42 are used to enable the conveyor belt 46 to circulate freely and play the role of pulling the conveyor belt 46. The positioning teeth 45 are driven by the positioning power device 32 to move the slide plate 41, so as to control the conveyor belt 46 to partially move to the bottom of the patch head 1, so as to ensure that the patch head 1 can absorb the patch components in the positioning fixture on the conveyor belt 46.

A displacement hole 421 is opened on the lifting bar 420, and the transmission wheel 412 is rollingly connected in the displacement hole 421.

[0037] Specifically, the regulating cylinder 411 drives the lifting bar 420 to rise and fall, and at the same time, the transmission wheel 412 is limited by the limit rotating plate 413 so that it can only rotate around the driving wheel 414, and the transmission wheel 412 is simultaneously limited to move in the displacement hole 421, so that when the transmission wheel 412 is driven to rise and fall by the lifting bar 420, it can only move around the driving wheel 414 in a short distance in the displacement hole 421, so as to achieve the purpose of completing the transmission connection of the transmission wheel 412 from being disengaged from or contacting with the displacement power device 33, so as to control the single feeding device 4 to transport the patch components; wherein when the driving wheel 414 and the transmission wheel 412 are in a horizontal position, the displacement power device 33 contacts the transmission wheel 412, and when the transmission wheel 412 rises, the displacement power device 33 and the transmission wheel 412 are in a disengaged state.

[0043] Specifically, the positioning motor 37 drives the rotating shaft 38 and a plurality of rotating gear rings 39 thereon to rotate, so that the rotating gear rings 39 drive the positioning teeth 45 of the feeding device 4 meshing therewith, thereby achieving the purpose of controlling the movement of the slide plate 41 .

[0044] In another embodiment of the present invention, the positioning power device 32 includes a displacement motor 35 and a displacement roller 36, the displacement motor 35 is installed on the slide 31 and the power rod is connected to one end of the displacement roller 36, the other end of the displacement roller 36 is movably connected to the slide 31, and the displacement roller 36 is frictionally connected to the friction ring 417 of the transmission wheel 412.
