[0019] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0020] See also Figure 1 , Figure 2 , Figure 7 As shown, the purpose of this embodiment is to provide an integrated suction and push loading machine, including a transfer component 1 and a segmentation component 2 arranged at one end of the transfer component 1, the transfer component 1 includes a combined frame 11 and an adsorption component 12 and an air control component 13 arranged on the combined frame 11, the combined frame 11 is transmission-connected with the adsorption component 12 to control the adsorption component 12 to adsorb the PCB board and lift it, and the air control component 13 is connected with the adsorption component 12 to control the adsorption of the adsorption component 12.

[0021] The slice assembly 2 includes a turnover frame 21 and a lifting member 22 and a horizontal push member 23 arranged on the turnover frame 21. The turnover frame 21 is located on one side of the combined frame 11 and is used to accommodate the PCB board. The combined frame 11 is connected to the lifting member 22 and the horizontal push member 23 in a transmission manner. The lifting member 22 is used to lift the PCB board. The horizontal push member 23 is used to push the bottom PCB board into the combined frame 11. The horizontal push member 23 is in contact with the air control 13. The turnover frame 21 equipped with multiple PCB boards is stuck on one side of the combined frame 11, or multiple PCBs are directly placed in the turnover frame 21. The lifting member 22 and the horizontal push member 23 are connected to the combined frame 11 in a transmission manner. After that, when the combined frame 11 drives the lifting piece 22 to lift the second layer and above PCB boards upward, the combined frame 11 drives the horizontal pushing piece 23 to push the bottom layer of PCB boards into the combined frame 11. In this process, the combined frame 11 will drive the adsorption piece 12 to adsorb and lift the PCB boards previously placed in the combined frame 11. When the adsorption piece 12 drives the PCB board to move to the top end and the horizontal pushing piece 23 pushes the PCB board into the combined frame 11, the horizontal pushing piece 23 contacts the air control piece 13, and the air control piece 13 controls the adsorption piece 12 to stop adsorbing the PCB, so that the PCB board can be transported.

[0022] The above structure is disclosed as follows: like Figure 2 , Figure 7 As shown, a part slot 211 for accommodating a PCB board is provided on the side of the turnover frame 21 away from the combined frame 11, a buckle 111 for clamping the bottom of the turnover frame 21 to prevent the turnover frame 21 from moving is provided at the bottom of the combined frame 11, and a third drive shaft 212 and a fourth drive shaft 213 are provided at the top of the turnover frame 21. The third drive shaft 212 is meshed with the fourth drive shaft 213, and one end of the fourth drive shaft 213 is plugged with a snap sleeve 214, and one end of the snap sleeve 214 is snap-fitted with the first drive shaft 114 of the motor set at the top of the combined frame 11. The third drive shaft 212 is connected to the lifting member 22 and the horizontal push member 23 for transmission, and the PCB board loaded is The turnover frame 21 is placed on one side of the combined frame 11, so that the buckle 111 clamps the bottom of the turnover frame 21 to avoid the movement of the turnover frame 21 when the PCB is put on, and the part slot 211 is exposed and the PCB board can be directly placed in the part slot 211. Through plug-in and snap-fit, after the turnover frame 21 is clamped on one side of the combined frame 11, the snap-fit ​​sleeve 214 is moved on the fourth drive shaft 213, so that one end of the snap-fit ​​sleeve 214 is clamped into the first drive shaft 114, so that the motor can drive the lifting member 22 and the horizontal push member 23 to perform the action through the meshing fourth drive shaft 213 and the third drive shaft 212.

[0023] like Figure 7 , Figure 8 , Figure 9As shown in the figure, when there are multiple PCB boards in the part slot 211, it is necessary to slice the stacked PCB boards to ensure that the PCB boards can enter the combination frame 11 one by one. A movable bracket 215 is slidably connected up and down at the top of the turnover rack 21. The bottom end of the third drive shaft 212 passes through the movable bracket 215 and is reciprocally threadedly connected to the movable bracket 215. An outer edge plate 216 is provided on the outer wall of the turnover rack 21. The outer edge plate 216 is a plate with a lifting slot opened on the side wall. The lifting slot is a parallelogram groove. The lifting member 22 includes a lifting plate 221 located in the part slot 211. One end of the lifting plate 221 is provided with an outer edge block 223 passing through the outer wall of the turnover rack 21. Both ends of the outer edge block 223 are located in the lifting slot and are slidably connected to the outer edge plate 216. A card slot 224 penetrating its upper and lower surfaces is opened in the middle of the outer edge block 223. The bottom ends of both ends of the movable bracket 215 pass through the card slot 224 and are horizontally slidably connected to the card slot 224. The end of the lifting plate 221 away from the outer edge block 223 is inserted and fitted with a friction block 222. The friction block 222 is connected to the inner wall of the lifting plate 221 through a first spring arranged. The horizontal pushing member 23 includes a horizontal pushing frame 231 slidably connected to the inner bottom of the part slot 211 and the inner bottom of the part slot 211. End plates 232 are symmetrically arranged at both ends of the horizontal pushing frame 231. A bottom plate 217 is arranged at the bottom end of the movable bracket 215. The end plates 232 pass through the outer wall of the turnover rack 21. The end plates 232 are slidably connected to the inclined slots arranged on the bottom plate 217 through cylindrical protrusions arranged on the surface. The motor drives the movable bracket 215 to make reciprocating up and down movements through the third drive shaft 212. The movable bracket 215 drives the outer edge block 223 to slide along the lifting slot of the outer edge plate 216, so that the lifting plate 221 contacts and drives the PCB boards on the second layer and above in the part slot 211 to move upward. Furthermore, the bottom plate 217 at the bottom end of the movable bracket 215 can drive the horizontal pushing frame 231 to slide along the inclined slot, and horizontally push the bottommost PCB board in the part slot 211 into the combination frame 11, thereby realizing the slicing process of the stacked PCB boards, which can reduce the manual labor intensity. Among them, the setting of the friction block 222 and the connection method through the first spring can not only ensure that the lifting plate 221 can drive multiple PCB boards to move upward, but also avoid the problem of PCB board deformation caused by excessive pressure on the PCB board.

[0024] After the horizontal pushing frame 231 pushes the bottommost PCB board into the combination frame 11, as the movable bracket 215 continues to drive the lifting plate 221 and the horizontal pushing frame 231 to move, the horizontal pushing frame 231 moves back to its original position into the part slot 211. And after the outer edge block 223 is driven by the movable bracket 215 to move to the high vertex position of the parallelogram groove structure of the lifting slot, it slides down along the lifting slot, so that the lifting plate 221 moves downward away from the PCB board. After multiple PCB boards fall to the bottom end of the part slot 211, the above process is continued to perform the slicing and pushing process of the PCB boards. In this process, it is necessary to perform the operation of loading the PCB board into the combination frame 11.

[0025] As Figure 2 , Figure 6 shown, when the PCB board is pushed into the bottom of the combined frame 11, it is necessary to adjust the angle of the PCB board to avoid jamming at the entrance of the conveying track 113 after the PCB board is loaded. Inner grooves 117 are provided at both ends of the bottom of the combined frame 11, and deviation-correcting plates 118 are inserted and fitted in the inner grooves 117. The deviation-correcting plates 118 are connected to the inner walls of the inner grooves 117 through the second springs provided. When the cross-pushing frame 231 pushes the PCB board into the bottom of the combined frame 11, the two ends of the cross-pushing frame 231 contact the inclined surfaces of the deviation-correcting plates 118, push the deviation-correcting plates 118 into the inner grooves 117, and then the cross-pushing frame 231 returns to the part groove 211. Under the elastic force of the second spring, the deviation-correcting plates 118 contact and correct the angle of the PCB board.

[0026] As Figure 2 , Figure 3 , Figure 4 shown, first, the PCB board pushed into the combined frame 11 is adsorbed and driven to move upward. The combined frame 11 is provided with a displacement frame 112 for guiding the movement of the suction attachment 12. A conveying track 113 for transporting the PCB board is provided at one end of the combined frame 11 away from the turnover frame 21. A second driving shaft 115 is rotatably connected to the combined frame 11. The top end of the second driving shaft 115 meshes with the first driving shaft 114. The suction attachment 12 includes a cover plate 121 and displacement shafts 122 symmetrically arranged at both ends of the cover plate 121. The displacement shafts 122 are located in the displacement frame 112 and are slidably connected to the displacement frame 112. A threaded connection end 123 is inserted and fitted on the side wall of the cover plate 121. The second driving shaft 115 passes through the threaded connection end 123 and is reciprocally threadedly connected to the threaded connection end 123. A suction cup 124 is provided at the bottom of the cover plate 121. An air outlet 125 and an air inlet 126 are provided at the top of the cover plate 121. A one-way air valve for controlling the unidirectional outflow of gas from the inside of the cover plate 121 is provided in the air outlet 125. The air inlet 126 is communicated with the air control member 13. The top of the suction cup 124 is communicated with the air outlet 125 and the air inlet 126. The second driving shaft 115 meshed with the first driving shaft 114 is driven by a motor to rotate, so that the second driving shaft 115 drives the cover plate 121 to move along the displacement frame 112 through the threaded connection end 123 that is reciprocally threadedly connected to it. When the cover plate 121 moves downward along the displacement frame 112, the suction cup 124 contacts the surface of the PCB board located at the bottom of the combined frame 11, and the cover plate 121 continues to move downward to squeeze the suction cup 124, and the air in the suction cup 124 is squeezed out through the air outlet 125. The gas flow direction is as Figure 4As shown by the solid arrow, the second drive shaft 115 then drives the cover plate 121 to move upward. Since the air in the suction cup 124 is exhausted, under the action of atmospheric pressure, the PCB board is adsorbed to the bottom of the suction cup 124, and the PCB board moves with the suction cup 124 to a position close to the transfer track 113.

[0027] When the PCB board is brought to the entrance position of the transfer track 113, it is necessary to release the adsorption and fixation between the suction cup 124 and the PCB board so that the PCB board can be transported through the transfer track 113. As Figure 5 、 Figure 9 shown, the air control device 13 includes an air control plate 131 provided at one end of the combined frame 11 and a hose 132 communicating with the top of the air control plate 131. The air control plate 131 is communicated with the air inlet 126 through the hose 132. An air passage for gas to pass through is provided in the air control plate 131. A baffle 133 for closing the air passage is provided at the bottom opening of the air passage. The baffle 133 is connected to the inner wall of the air passage through a third spring provided. A plate convex 233 is correspondingly provided at one end of the end plate 232 close to the combined frame 11. When the cover plate 121 drives the PCB to reach the entrance position of the transfer track 113, the horizontal push frame 231 just enters the inner bottom of the combined frame 11 along the inclined groove of the bottom plate 217, and the plate convex 233 contacts and pushes the baffle 133 to move into the air passage against the elastic force of the third spring, as Figure 10 shown, the external air flow can enter the air control plate 131 from the bottom opening of the air passage, and then enter the suction cup 124 through the air inlet 126. The gas flow direction is as Figure 4 shown by the dotted arrow in the figure, so that the suction cup 124 cannot adsorb the PCB board, and the PCB board can be transported through the transfer track 113.

[0028] It should be noted that the thickness of the PCB board has specifications such as 0.6mm, 1.0mm, 1.6mm, 2.0mm, 2.4mm, etc. After the PCB board is loaded onto the board, in order to facilitate PCB boards of different specifications to enter the transfer track 113, as Figure 2 shown, the transfer track 113 is slidably connected to the combined frame 11 up and down. One end of the combined frame 11 is rotatably connected with a screw rod 116. The bottom of the screw rod 116 passes through the transfer track 113 and is threadedly connected to the transfer track 113. By rotating the transfer track 113, the transfer track 113 can be driven to slide up and down, changing the relative height between the transfer track 113 and the top end of the displacement frame 112, so as to facilitate PCB boards of different specifications to fall into the entrance end of the transfer track 113.

[0029] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, which are not used to limit the present invention.
