[0002] In the PCB manufacturing process, the exposure machine is one of the key equipment, and its loading and unloading efficiency has a significant impact on the production efficiency of the PCB. At present, the loading and unloading of the exposure machine mostly uses manual or simple mechanical devices to directly move the PCB boards from the material rack to the exposure machine workbench, or to remove the PCB boards from the exposure machine workbench after exposure and place them on the material rack. This method has many problems. On the one hand, manual loading and unloading is labor-intensive, inefficient, and prone to operational errors, which affect product quality. On the other hand, simple mechanical devices cannot effectively cache the PCB boards. When the exposure machine fails or the production rhythm does not match, it is easy to cause the loading and unloading to be interrupted, which in turn affects the continuity of the entire production line. In addition, the existing exposure machine loading and unloading equipment has difficulty in accurately controlling the conveying order and quantity of the PCB boards, and cannot meet the diverse requirements of different production processes for the loading rhythm of PCB boards.

DETAILED DESCRIPTION

[0018] 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.

[0019] See also Figure 1-18 The present invention provides a technical solution: a PCB clip cache docking exposure machine loading and unloading device, comprising: a clip cache loading mechanism 1, a docking exposure and transfer mechanism 2, and a clip cache unloading mechanism 3. The clip cache loading mechanism 1 and the clip cache unloading mechanism 3 are respectively arranged on the left and right sides of the docking exposure and transfer mechanism 2. A plurality of PCB plates are equidistantly placed in the PCB clip in a pull-out manner. The clip cache loading mechanism 1 loads the PCB plates in the PCB clip one by one to the docking exposure and transfer mechanism 2 for exposure. Then, the clip cache unloading mechanism 3 collects the PCB plates and sends them to an empty PCB clip for unloading.

[0020] The magazine buffer loading mechanism 1 comprises a magazine trolley 11 , which is used to transport the magazine bin 121 ; The magazine buffer feeding mechanism 1 also includes a first magazine feeding conveyor line 12, which is connected to a magazine lifting mechanism 13. An empty basket outflow conveyor line 123 is arranged above the first magazine feeding conveyor line 12 in parallel. One side of the magazine lifting mechanism 13 is connected to a second magazine feeding conveyor line 16. A cache mechanism 15 is arranged across the discharge end of the second magazine feeding conveyor line 16. The second magazine feeding conveyor line 16 is connected to a PCB sheet alignment mechanism 14. The magazine bins 121 are fed one by one onto the first magazine feeding conveyor line 12. The first magazine feeding conveyor line 12 feeds the magazine bins 121 onto the magazine lifting mechanism 13. Then, the second magazine feeding conveyor line 16 starts to output the PCB sheets one by one from the bottom of the magazine bins 121. Each time a PCB sheet is output, the magazine lifting mechanism 13 drives the magazine bins 121 to descend one grid. After the magazine bins 121 are emptied, the magazine lifting mechanism 13 lifts the magazine bins 121 to the empty basket outflow conveyor line 123, and the empty basket outflow conveyor line 123 outputs the PCB sheets. During the output process, the buffer mechanism 15 buffers the PCB boards according to the actual rhythm.

[0021] The first magazine feeding conveyor line 12 and the empty flower basket outflow conveyor line 123 are both automated conveyor lines. The loading and unloading ends of the first magazine feeding conveyor line 12 and the empty flower basket outflow conveyor line 123 are both provided with photoelectric sensors 124 for sensing the position of the magazine bin 121.

[0023] A side push cylinder 132 is provided on the bottom side of the basket lifting loading and unloading structure 133 to push the magazine bin 121 to a specified position.

[0024] Specifically, the basket lifting loading and unloading structure 133 includes a lifting cover 1331, a magazine lifting plate 1333, and a photoelectric sensor group 137. The lifting cover 1331 and the magazine lifting plate 1333 are fixedly connected at the four corners with fixed connecting rods 1336. The magazine lifting plate 1333 is provided with a magazine loading and unloading transport line 1334 and a side push cylinder 132. The photoelectric sensor group 137 includes a height sensor 1371 and a magazine position sensor 1373. 1371 is installed on the lower surface of the magazine lifting plate 1333, and is used to monitor the height of the magazine lifting plate 1333 in real time. The magazine position sensor 1373 is fixedly installed on the lower surface of the lifting cover 1331, and is used to sense the entry and exit of the magazine bin 121. The magazine loading and unloading transport line 1334 cooperates with the first magazine loading conveyor line 12 to receive the fully loaded magazine bin 121 and output the empty magazine bin 121. The side push cylinder 132 is used to return the fully loaded magazine bin 121 to its original position.

[0025] The magazine loading and unloading transport line 1334 includes a first servo motor 1341, a transmission rod 1342 and a conveyor belt 1343.

The first servo motor 1341 drives the connected transmission rod 1342 through the transmission pulley group to realize the servo movement of the conveyor belt 1343, receiving the magazine bin 121 delivered by the first magazine loading conveyor line 12, and after being lifted by the first lifting module 131, the empty magazine bin 121 is output to the empty flower basket outflow conveyor line 123.

[0026] The side push cylinder 132 includes a linear cylinder 1351 and a fixed clamping rod. The linear cylinder 1351 drives the connected positioning push rod 1352. The fixed clamping rod and the positioning push rod 1352 are arranged on both sides above the conveyor belt 1343. When the magazine bin 121 enters the magazine loading and unloading transport line 1334, the positioning push rod 1352 is advanced by the linear cylinder 1351, and cooperates with the fixed clamping rod to clamp and position the magazine bin 121, so that the magazine bin 121 is aligned with the second magazine loading conveyor line 16, and the stability of the magazine bin 121 is maintained during lifting.

[0027] A top downward positioning cylinder 138 is also installed on the lifting cover 1331. When the sheet is output, the top downward positioning cylinder 138 presses the top of the magazine bin 121 to further fix the magazine bin 121.

[0028] A silicon wafer alignment mechanism 17 is provided on the side of the second clip loading conveyor line 16 to align the PCB wafers entering the second clip loading conveyor line 16 .

[0029] The second conveyor line 16 for magazine loading includes a linearly movable tongue plate 1615, which moves and inserts into the bottom of the fully loaded magazine bin 121. A main conveyor belt 1617 is provided on the linearly movable tongue plate 1615, and the sheets in the magazine bin 121 are placed one by one on the main conveyor belt 1617 for output.

[0030] The linear movable tongue plate 1615 is fixedly installed on the movable seat 1618, and the movable seat 1618 is slidably connected to the slide rail 1619. The slide rail 1619 is fixedly installed on the support platform 1611. A linear transfer pulley group 1612 is provided on the support platform 1611. The belt of the linear transfer pulley group 1612 is fixedly connected to the movable seat 1618. A pulley group servo drive motor 1616 is installed at the end of the support platform 1611. The pulley group servo drive motor 1616 drives the linear transfer pulley group 1612, driving the movable seat 1618 to slide linearly along the slide rail 1619, thereby driving the linear movable tongue plate 1615 to enter and exit the magazine bin 121 linearly.

[0031] A pair of first guide wheels 1651 are rotatably mounted on both sides of the front end of the linearly movable tongue plate 1615. A fixed seat 1613 is also mounted on the support platform 1611. A pair of second guide wheels 1631, a pair of fourth guide wheels 1632, and a pair of third guide wheels 1633 are mounted on the fixed seat 1613. Each pair of first guide wheels 1651, second guide wheel 1631, fourth guide wheel 1632, and third guide wheel 1633 are coaxially fixedly connected, wherein the third guide wheel 1633 is connected to the conveyor belt servo drive motor 1614 via a transmission pulley assembly. The second conveyor line 16 for magazine loading also includes a pair of fifth guide wheels 1620 and a pair of sixth guide wheels 1641, wherein the fifth guide wheel 1620 is rotatably set on the support platform 1611, and the fifth guide wheel 1620 is located at one end close to the silicon wafer straightening mechanism 17, and the sixth guide wheel 1641 is rotatably installed on the movable seat 1618. The main conveyor belt 1617 passes through the first guide wheel 1651, the second guide wheel 1631, the third guide wheel 1633, the fourth guide wheel 1632, the fifth guide wheel 1620 and the sixth guide wheel 1641 in sequence, and then returns to the first guide wheel 1651. Since the sixth guide wheel 1641 moves with the movable seat 1618, the main conveyor belt 1617 is still in a tensioned state when the linear movable tongue plate 1615 moves.

[0032] The silicon wafer correcting mechanism 17 is arranged at the loading end of the second conveyor line 16 for magazine loading. The silicon wafer correcting mechanism 17 includes a fixed seat plate 1721, on which a linear slide 1722 and a screw structure are arranged. Two symmetrical movable platforms 1723 are arranged on the linear slide 1722 and the screw structure. A correcting arm 1724 is fixedly installed on the movable platform 1723, and a plurality of correcting wheels 1725 are installed on the correcting arm 1724. The correcting wheels 1725 are located on both sides of the linear movable tongue plate 1615. A second servo motor 1726 is also installed on the fixed seat plate 1721. The second servo motor 1726 drives the connected screw structure. The two movable platforms 1723 are driven by the screw structure to move closer or farther away along the linear slide 1722, thereby driving the correcting arm 1724 to move closer or farther away, thereby correcting the sheet passing above it.

[0033] The cache mechanism 15 includes a second linear servo lifting module 151 and a lifting bracket 152. The second linear servo lifting module 151 drives the lifting bracket 152 to rise and fall.

The cache cam 1532 is inserted into the socket 1531. The cache cam 1532 is located on both sides of the second conveyor line 16 for magazine loading. When it is necessary to cache sheets, the sheets stop after passing through the cache cam 1532. The second linear servo lifting module 151 lifts the cache cam 1532 and lifts the sheet away from the second conveyor line 16 for magazine loading to achieve caching. Conversely, the second linear servo lifting module 151 drives the lifting bracket 152 to descend and places the sheets cached therein onto the second conveyor line 16 for magazine loading to achieve re-loading of the sheets.

[0034] The PCB material correction mechanism 14 includes a base plate 141, on which a first servo drive motor 142 is installed. The first servo drive motor 142 drives a connected streamline transmission line 144. The streamline transmission line 144 is a dual-channel transfer line. A linear servo module 147 is provided at the bottom of the base plate 141 to drive linear movement, which is used to connect the two channels to the second magazine loading conveyor line 16 to receive PCB materials.

[0038] Two sets of variable-distance suction cup structures 221 are installed on the loading and unloading lifting arm 22 and the unloading lifting arm 24. The variable-distance suction cup structures 221 are connected to the vacuum generator 222. The vacuum generator 222 generates suction in the variable-distance suction cup structures 221 through negative pressure to suck the PCB sheets on the flow line transmission line 144. The unloading lifting arm 24 is used to adsorb the PCB sheets for unloading.

[0039] The variable pitch suction cup structure 221 for loading and unloading is driven by a linear servo drive module to change the pitch.

[0040] The docking exposure and transplanting mechanism 2 also includes a docking exposure machine 23, which is located on one side of the transplanting linear module 21.

The flower basket lifting mechanism 33 is connected to the unloading transport line 34. The structure of the magazine cache unloading mechanism 3 is the same as that of the magazine cache loading mechanism 1 , except that the magazine cache unloading mechanism 3 collects the PCB sheets and feeds them into the magazine.

[0043] Working principle: The magazine bin 121 filled with PCB sheets is sent to the magazine cache loading mechanism 1 by the magazine trolley 11. The magazine cache loading mechanism 1 takes out the PCB sheets from the magazine bin 121 one by one and sends them to the docking exposure and transplanting mechanism 2 for exposure. After exposure, the magazine cache unloading mechanism 3 collects them one by one and sends them to the empty magazine bin 121 for storage.
