[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Figure 1 , Figure 2 and Figure 3 A hidden circuit board support separation processing mechanism shown in the figure includes a main frame 1 and an electrically controlled support conveying roller 2 installed inside the main frame 1, an electrically controlled flip support rod 3 is movably installed on the bottom side of the electrically controlled support conveying roller 2 inside the main frame 1, an overhead crossbeam 6 is installed above the electrically controlled support conveying roller 2 inside the main frame 1 through a flip bracket 5, an electrically controlled top drive seat 7 is installed at the lower end of the overhead crossbeam 6, electrically controlled transverse guide wheels 9 are installed on the bottom sides of both sides of the electrically controlled top drive seat 7 through elastic extrusion rods 8, and combined material guide reflux hoods 10 are installed on both sides of the electrically controlled transverse guide wheels 9 on the elastic extrusion rods 8.

[0031] The circuit board is conveyed in translation by the electrically-controlled supporting conveying rollers 2, and then after it moves to the specified position, the electrically-controlled flip support rods 3 lift and separate it, and then the electrically-controlled top driving seat 7 applies glue to the specified position on the circuit board through the electrically-controlled horizontal guide wheels 9 at the bottom of the two sides of the elastic squeezing rods 8.

[0032] In order to cooperate with the flipping and telescopic adjustment, a bottom cross beam 11 is fixed inside the main frame 1 at the bottom side of the electrically controlled supporting conveyor roller 2. The electrically controlled flip support rod 3 includes a lateral flip cylinder 31 movably installed on the outside of the bottom cross beam 11 through a transverse axis, an internal telescopic support rod 32 axially fixed inside the lateral flip cylinder 31, a lateral flip support rod 33 movably assembled between the bottom cross beam 11 and the lateral flip cylinder 31, an overhead lifting bracket 34 slidably sleeved on the outside of the lateral flip cylinder 31, and a pressure sensor module 35 installed on the side wall of the overhead lifting bracket 34.

[0033] The lateral flip strut 33 and the internal telescopic strut 32 are both existing technologies. The internal telescopic strut 32 controls the lifting and lowering of the overhead lifting bracket 34 by telescoping, while the lateral flip strut 33 controls the flipping of the lateral flip cylinder 31 by telescoping. In this way, the lateral limiting can be performed on all sides of the circuit board, and then clamped, lifted and separated, and finally the circuit board can be positioned and fixed at a specified height and position, which will not affect the subsequent transportation of the circuit board.

[0034] In order to lock and fix the angle of the flip bracket 5, 9 lateral limit through holes 12 are opened on the outer walls of both sides of the main frame 1 on the contact surface of the flip bracket 5. The flip bracket 5 is fixedly connected to the side wall of the main frame 1 through the inner locking bolts 13 that pass through the lateral limit through holes 12.

[0035] In order to cooperate with the top adjustment, the lower surface of the top crossbeam 6 is fixedly equipped with a top guide rail 61 for installing an electrically controlled top drive seat 7. The electrically controlled top drive seat 7 includes an internal movable seat 71 installed inside the top guide rail 61, bottom electric drive wheels 72 installed on both sides of the lower end of the internal movable seat 71, bottom support wheels 73, top limiting wheels 74 installed on both sides of the upper end of the internal movable seat 71, and a raw material diversion chamber 75 opened inside the internal movable seat 71.

[0036] The bottom electric drive wheel 72 is a prior art, and drives the internal moving seat 71 to translate and adjust inside the top guide rail 61 by rotating.

[0037] In order to facilitate installation and control, the upper end of the elastic extrusion rod 8 is fixedly installed on the bottom of the internal movable seat 71 and is connected to the inside of the raw material guide chamber 75. The two sides of the bottom of the elastic extrusion rod 8 are fixedly assembled with L-shaped lateral mounting brackets 76 by bolts, and the lateral mounting bracket 76 is fixedly assembled with a lateral electric control support rod 77 for controlling the electric-controlled transverse guide wheel 9.

[0038] The lateral electrically controlled support rod 77 is a prior art, which adjusts the distance between the electrically controlled transverse guide wheel 9 and the operating surface by telescoping.

[0039] In order to facilitate assembly, a bottom side frame 78 for installing the electrically controlled transverse guide wheel 9 is fixedly mounted on the bottom telescopic section of the lateral electrically controlled support rod 77 .

[0040] The electrically controlled transverse guide wheel 9 is installed on one side of the bottom side frame 78, and the lateral electrically controlled support rod 77 is adjusted for telescopic movement by driving the bottom side frame 78.

[0041] In order to cooperate with the heating material guide and scraping material return, the combined material guide return cover 10 includes a first lateral air guide cover 101 fixed on one side of the bottom side frame 78, a second lateral air guide cover 102 fixed on the other side of the bottom side frame 78, an arc-shaped scraper plate 103 fixed on the inner side of the first lateral air guide cover 101, a lateral return pipe 104 fixed on the outer side of the first lateral air guide cover 101, an electrically controlled screw conveying rod 105 installed inside the lateral return pipe 104 and an electrically controlled heating module 106 fixed inside the second lateral air guide cover 102.

[0042] An internal reflux port is provided inside the first lateral air guide cover 101 between the arc scraper plate 103 and the lateral reflux pipe 104. When the electrically controlled transverse guide wheel 9 rotates, the curved scraper plate 103 is used to scrape the raw materials after the glue coating to the inside of the internal reflux port, and then the raw materials are returned to the raw material guide chamber 75 through the electrically controlled spiral conveying pipe 105, and then the materials are circulated and guided to avoid hardening of the outer wall of the electrically controlled transverse guide wheel 9 over time. The direction of the electrically controlled transverse guide wheel 9 is fixed, and no matter how the electrically controlled transverse guide wheel 9 is translated, its rotation direction is always consistent, thereby ensuring the stability of material discharging and material returning.

[0043] In order to cooperate with the top diversion, the upper end of the lateral return pipe 104 is equipped with a top diversion pipe 107 which is connected to the inside of the raw material diversion chamber 75.

[0044] In order to monitor the telescopic pressure of the elastic extrusion rod 8 and thus facilitate control, an embedded pressure sensor 81 for monitoring pressure changes is installed at the telescopic end of the elastic extrusion rod 8 .

[0045] When the internal telescopic support rod 32 and the lateral flip support rod 33 are started, the top lifting bracket 34 is driven to squeeze, lift and separate the four sides of the circuit board, so that the circuit board is lifted to a preset position. At this time, the glue-coated surface on the circuit board will squeeze the bottom electric drive wheel 72, thereby squeezing and adjusting the elastic squeezing rod 8.

[0046] In order to monitor the gluing position and control the extension and retraction, infrared monitoring and positioning modules 108 are fixedly mounted on the outer sides of the first lateral air guide cover 101 and the second lateral air guide cover 102 .

[0047] The infrared monitoring and positioning module 108 monitors the bottom distance by emitting infrared rays downward through the infrared emitting port at the bottom. When the feeding end detects the circuit board entering, the internal telescopic support rod 32 and the lateral flip support rod 33 are automatically controlled to start, driving the top lifting bracket 34 to extrude, lift and separate the circuit board around, so that the circuit board is lifted to a preset position. After the lifting correction, the bottom electric drive wheels 72 on both sides of the lower end of the internal moving seat 71 are started, driving the internal moving seat 71 to translate along the top guide rail 61. The elastic extrusion rod 8 can not only drive the bottom electric drive wheel 72 to translate, but also guide the raw material inside the internal raw material diversion chamber 75 to the surface of the bottom electric drive wheel 72 for gluing operation. An extrusion mechanism with the same structural principle as the electric-controlled screw conveying rod 105 is also installed inside the elastic extrusion rod 8, and it also has an electric heating function to ensure the efficiency and stability of raw material extrusion.

The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
