[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

The feeder base 1 is used to support the feeder 12. The feeder base 1 is used to support the feeder 12.

[0030] The adjusting mechanism includes a fixed plate 2, a screw rod 21, a height limiting plate 22 and a transmission assembly; the two fixed plates 2 are respectively fixed to the outside of the No. 1 side plate 13 and the No. 2 side plate 15; the screw rod 21 is rotatably connected to the inner wall of the fixed plate 2, and the screw rod 21 is rotatably connected to the inner wall of the shelf plate 16; the height limiting plate 22 is slidably connected to the inner wall of the shelf plate 16, and the height limiting plate 22 is threadedly engaged with the screw rod 21; the transmission assembly is arranged at the top end of the No. 1 side plate 13 and the No. 2 side plate 15, and the transmission assembly is used to adjust the gap between the height limiting plate 22 and the shelf plate 16 for placing the PCB board; when PCB boards of different thicknesses are placed and loaded, the two fixed plates 2 respectively rotate the two screw rods 21 installed on the outside of the No. 1 side plate 13 and the No. 2 side plate 15, and use the No. 1 electric slide The block 14 drives the second side plate 15 to slide close to the first side plate 13. The transmission assembly drives multiple screw rods 21 to rotate synchronously during the sliding process of the second side plate 15. The screw rods 21 cooperate with the height limiting plate 22 to rotate with the thread. The height limiting plate 22 slides down on the outside of the screw rod 21, and the shelf plate 16 remains in place. The rotation shrinks the gap between the height limiting plate 22 and the shelf plate 16, which is suitable for placing thinner PCB boards. When the No. 1 electric slider 14 drives the No. 2 side plate 15 to slide away from the No. 1 side plate 13, the transmission assembly drives multiple screw rods 21 to rotate in the opposite direction, so that the height limiting plate 22 can be moved away from the shelf plate 16, and the gap between the height limiting plate 22 and the shelf plate 16 is expanded, which is suitable for placing thicker PCB boards, and plays a role in placing and loading PCB boards of different thicknesses.

[0031] like Figures 1 to 4 As shown, the transmission assembly includes a No. 1 gear plate frame 3, a No. 1 gear 31, a No. 2 gear plate frame 32 and a No. 2 gear 33; the No. 1 gear plate frame 3 is fixed to the top of the No. 1 side plate 13; the No. 1 gear 31 is fixed to the top of the screw rod 21 outside the No. 2 side plate 15, and the No. 1 gear 31 is meshed with the teeth on the No. 1 gear plate frame 3; the No. 2 gear plate frame 32 is fixed to the top of the No. 2 side plate 15; the No. 2 gear 33 is fixed to the top of the screw rod 21 outside the No. 1 side plate 13, and the No. 2 gear 33 is meshed with the teeth on the No. 2 gear plate frame 32; when the No. 2 side plate 15 slides close to the No. 1 side plate 13, the teeth on the No. 2 gear plate frame 32 and the No. 2 gear are meshed. The No. 1 gear 33 meshes and rotates, thereby driving the screw rod 21 installed on the outside of the No. 1 side plate 13 to rotate forward, and the No. 1 gear 31 on the screw rod 21 outside the No. 2 side plate 15 moves synchronously with the No. 2 side plate 15, and the No. 1 gear 31 meshes and rotates with the teeth on the No. 1 gear plate frame 3, thereby driving the screw rod 21 installed on the outside of the No. 2 side plate 15 to rotate forward, thereby achieving the contraction of the gap between the multiple height limiting plates 22 and the shelf plates 16. If the No. 2 side plate 15 slides in the opposite direction, it drives the multiple screw rods 21 to rotate in the opposite direction, thereby achieving the expansion of the gap between the multiple height limiting plates 22 and the shelf plates 16, thereby playing the role of adjusting the gap between the multiple height limiting plates 22 and the shelf plates 16.

[0032] like Figure 1 and Figure 2 As shown, the pushing assembly includes a pushing rack 4, an electric cylinder No. 1 41 and a pushing block 42; the two pushing racks 4 are fixedly connected to the top of the loading base 1; the electric cylinder No. 1 41 is fixedly connected to the top of the pushing rack 4; the pushing block 42 is fixedly connected to the output end of the electric cylinder No. 1 41; when pushing the PCB board temporarily placed on the shelf 16, the pushing rack 4 is used to support the electric cylinder No. 1 41 to be flush with the position of the top shelf 16, and the output end of the electric cylinder No. 1 41 is extended, driving the pushing block 42 to contact the PCB board on the top shelf 16 and push the PCB board to the feeding assembly for loading and processing, and then the electric cylinder No. 1 41 drives the pushing block 42 to retract and reset, and the hydraulic cylinder drives the placement rack 12 to rise to a height, which is the gap height between the two high and low shelf plates 16, thereby repeating the steps to push the PCB board for loading, thereby playing the role of pushing and loading the PCB board.

[0033] like Figures 1 to 6 As shown, the outside of the pushing block 42 is fixed with an extrusion plate 5; the top of the shelf plate 16 outside the No. 1 side plate 13 is slidably connected to the limit block 51, and there are two limit blocks 51; the inside of the shelf plate 16 is slidably connected to a sliding plate 52 near the limit block 51, and an elastic member is connected between the sliding plate 52 and the shelf plate 16; the top of the sliding plate 52 is provided with a groove 53, and the groove 53 corresponds to the bottom end of the limit block 51; when the PCB board is temporarily stored on the shelf plate 16, due to the operation of the equipment and the process of the placement rack 12 rising, it is easy to shake, causing the PCB board temporarily stored on the shelf plate 16 to be skewed and affect the pushing, The two limit blocks 51 are used to limit the PCB boards temporarily stored on the shelf plate 16, thereby reducing the situation where the PCB boards are temporarily stored on the shelf plate 16 due to equipment shaking and skewing. During the pushing process, the extrusion plate 5 is fixed to the outside of the pushing block 42, and the extrusion plate 5 corresponds to the sliding plate 52 installed on the shelf plate 16. As the pushing block 42 drives the extrusion plate 5 to slide forward to push the PCB board, the extrusion plate 5 will first squeeze the sliding plate 52 and squeeze the sliding plate 52 into the interior of the shelf plate 16. The elastic part contracts and is stressed, and the limit block 51 falls into the interior of the groove 53, contacting the two limit blocks 51 to limit the PCB boards on the shelf plate 16, and the sliding plate 52 can push the PCB board to be loaded.

[0034] like Figure 1 and Figure 2As shown, the feeding assembly includes a conveyor frame 6 and a conveyor 61; the two conveyor frames 6 are fixedly connected to the top of the loading base 1, and the conveyor frame 6 is arranged opposite to the pushing frame 4; the conveyor 61 is installed on the top of the conveyor frame 6; when feeding the PCB board, the conveyor frame 6 supports the conveyor 61 and is installed on the opposite side of the pushing block 42 at the top of the loading base 1, and the conveyor belt of the conveyor 61 is level with the shelf plate 16, and the pushing block 42 is used to push the PCB board on the shelf plate 16 to the conveyor belt of the conveyor 61, thereby playing the role of feeding and processing the PCB board.

[0035] A detector 7 is installed at the top of the conveyor 61; the detector 7 is used to detect the quality of PCB boards. When multiple PCB boards are fed on the conveyor belt of the conveyor 61, the detector 7 is fixed to the front end of the conveyor 61, and the push block 42 pushes the PCB boards onto the conveyor belt of the conveyor 61 for feeding. Every PCB board passing the bottom end of the detector 7 will be inspected. The detector 7 detects scratches, impurities, damage and other problems on the PCB boards. If a quality problem is detected in the PCB board, the PCB board with the quality problem will be marked immediately, thereby playing a role in PCB board quality inspection.

[0036] The detector 7 is fixedly connected to the outside of the placement rack 12 with a support frame 8; the outside of the support frame 8 is slidably connected to a No. 2 electric slider 81; the bottom end of the No. 2 electric cylinder 82 is fixedly connected to the No. 2 electric cylinder 82; the bottom end of the No. 2 electric cylinder 82 is installed with an adsorber 83; when the PCB board is conveyed on the conveyor 61, the detector 7 detects that the PCB board has quality problems. As the conveyor 61 continues to convey the PCB board, the PCB board is sent to the bottom end of the adsorber 83. The adsorber 83 is an adsorption device similar to a vacuum adsorption pump. The output end of the No. 2 electric cylinder 82 drives the adsorber 83 to adsorb the PCB board with quality problems. Then the No. 2 electric cylinder 82 adsorbs and sorts the PCB board out. The No. 2 electric slider 81 drives the adsorbed PCB board away from the conveyor 61, thereby sorting the PCB boards with quality problems.

[0037] like Figure 1 and Figure 2 As shown, a temporary storage box 9 is fixedly connected to the outside of the conveyor 61; an anti-drop component is provided inside the temporary storage box 9, which is used to store the PCB boards stably; after the PCB boards with quality problems are sorted out, the temporary storage box 9 is installed on the side of the conveyor 61, and the No. 2 electric cylinder 82 cooperates with the adsorber 83 to suck out the PCB boards with quality problems, and the No. 2 electric slide 81 drives the PCB boards with quality problems to slide to the top of the temporary storage box 9, and then the adsorber 83 releases the PCB boards, and the PCB boards fall into the interior of the temporary storage box 9, and the anti-drop component prevents the PCBs from falling, thereby playing the role of collecting and temporarily storing the PCB boards with quality problems.

[0038] The anti-fall component includes a support slide 91 and a spring; the support slide 91 is slidably connected to the inner wall of the temporary storage box 9; a plurality of the springs are fixed between the temporary storage box 9 and the support slide 91; when temporarily storing PCB boards with quality problems, the No. 2 electric cylinder 82 drives the PCB board adsorbed by the absorber 83 to extend close to the support slide 91, and the absorber 83 releases the PCB board so that it falls into the temporary storage box 9. The PCB board with quality problems will fall directly on the top of the support slide 91. Due to the weight of the PCB board itself, every time a PCB board is stacked on the support slide 91, the support slide 91 will press down the spring under gravity to contract. The spring is not shown in the figure. The spring is installed between the support slide 91 and the temporary storage box 9. The support of the spring can shorten the telescopic distance of the No. 2 electric cylinder 82, accelerate the reset speed of the absorber 83, and the spring can play a buffering role when the PCB board is lowered.

[0039] Working process: When processing and loading PCB boards, since multiple types of PCB boards will be prepared in the factory, different types of PCB boards need to be loaded. The loading base 1 is the main support of the entire loading equipment. A plurality of No. 1 side panels 13 and No. 2 side panels 15 are installed on the placement rack 12. First, the No. 1 electric slider 14 is used to drive the No. 2 side panel 15 to slide closer to the No. 1 side panel 13, which can adjust the placement width of the PCB board, and cooperate with the adjustment mechanism to adjust the storage thickness gap of the PCB board, and cooperate with the shelf plate 16 to temporarily store multiple PCB boards of different types, and then the placement rack 12 is moved to the corresponding clamping block 11 on the top of the hydraulic cylinder, and pushed. The feeding assembly pushes the PCB boards stored on the two top shelf plates 16, and the PCB boards are pushed onto the feeding assembly. Then the output end of the hydraulic cylinder drives the placement rack 12 to slide up as a whole, and the pushing assembly pushes the PCB boards sliding up below in turn, thereby realizing the function of loading PCB boards of different models; when PCB boards of different thicknesses are placed and loaded, the two fixed plates 2 rotate the two screw rods 21 to be installed on the outside of the No. 1 side plate 13 and the No. 2 side plate 15 respectively, and the No. 1 electric slider 14 is used to drive the No. 2 side plate 15 to slide close to the No. 1 side plate 13. The transmission assembly drives multiple screw rods 21 to rotate synchronously during the sliding process of the No. 2 side plate 15, and the screw rods 21 and the limit The high plate 22 cooperates with the thread to rotate, and the height limiting plate 22 slides down on the outside of the screw rod 21, while the shelf plate 16 remains in place. The rotation shrinks the gap between the height limiting plate 22 and the shelf plate 16, which is suitable for placing thinner PCB boards. When the No. 1 electric slider 14 drives the No. 2 side plate 15 to slide away from the No. 1 side plate 13, the transmission assembly drives the multiple screw rods 21 to rotate in the opposite direction, thereby enabling the height limiting plate 22 to move away from the shelf plate 16, and the gap between the height limiting plate 22 and the shelf plate 16 is expanded, which is suitable for placing thicker PCB boards and plays a role in placing and loading PCB boards of different thicknesses; when the No. 2 side plate 15 slides close to the No. 1 side plate 13, the No. 2 gear plate frame 3 The teeth on the gear 2 mesh with the second gear 33 and rotate, thereby driving the screw rod 21 installed on the outside of the No. 1 side plate 13 to rotate forward, and the No. 1 gear 31 on the screw rod 21 outside the No. 2 side plate 15 moves synchronously with the No. 2 side plate 15, and the No. 1 gear 31 meshes with the teeth on the No. 1 gear plate frame 3 and rotates, thereby driving the screw rod 21 installed on the outside of the No. 2 side plate 15 to rotate forward, thereby shrinking the gap between the multiple height limiting plates 22 and the shelf plate 16. If the No. 2 side plate 15 slides in the opposite direction, it drives the multiple screw rods 21 to rotate in the opposite direction, thereby expanding the gap between the multiple height limiting plates 22 and the shelf plate 16, thereby adjusting the gap between the multiple height limiting plates 22 and the shelf plate 16;

[0040] When pushing the PCB board temporarily placed on the shelf 16, the pushing frame 4 is used to support the No. 1 electric cylinder 41 to be flush with the position of the top shelf 16, and the output end of the No. 1 electric cylinder 41 extends, driving the pushing block 42 to contact the PCB board on the top shelf 16 and push it, pushing the PCB board to the feeding assembly for loading and processing, and then the No. 1 electric cylinder 41 drives the pushing block 42 to retract and reset, and the hydraulic cylinder drives the placement frame 12 to rise a height, which is the height of the gap between the two high and low shelf boards 16, thereby repeating the steps to push the PCB board into the feed, playing the role of pushing and loading the PCB board; when the PCB board is temporarily stored on the shelf 16, due to the operation of the equipment and the process of the placement frame 12 rising, it is easy to jitter, leading to The PCB boards temporarily stored on the shelf plate 16 are easily skewed and affected in pushing. The two limit blocks 51 are used to limit the PCB boards temporarily stored on the shelf plate 16, thereby reducing the skew of the PCB boards on the shelf plate 16 due to the shaking of the equipment. During the pushing process, the extrusion plate 5 is fixed to the outside of the pushing block 42, and the extrusion plate 5 corresponds to the sliding plate 52 installed on the shelf plate 16. As the pushing block 42 drives the extrusion plate 5 to slide forward to push the PCB board, the extrusion plate 5 will first squeeze the sliding plate 52, and squeeze the sliding plate 52 into the inside of the shelf plate 16. The elastic member contracts and is stressed, and the limit block 51 falls into the inside of the groove 53, contacts the limit of the PCB boards on the shelf plate 16 by the two limit blocks 51, and the sliding plate 52 can push the PCB board to be fed.

[0041] When feeding PCB boards, the conveyor frame 6 supports the conveyor 61 and is installed on the opposite side of the pushing block 42 at the top of the loading base 1, and the conveyor belt of the conveyor 61 is level with the shelf 16, and the pushing block 42 is used to push the PCB boards on the shelf 16 to the conveyor belt of the conveyor 61, thereby playing the role of feeding and processing the PCB boards; when multiple PCB boards are fed on the conveyor belt of the conveyor 61, the detector 7 is fixed on the front end of the conveyor 61, and the pushing block 42 pushes the PCB boards to the conveyor belt of the conveyor 61 for feeding. Every PCB board passing the bottom end of the detector 7 will be detected, and the detection The detector 7 detects scratches, impurities and damage on the PCB board. If a quality problem is detected on the PCB board, the PCB board with the quality problem will be marked immediately, which plays a role in quality inspection of the PCB board. When the PCB board is conveyed on the conveyor 61, the detector 7 detects that there is a quality problem on the PCB board. As the conveyor 61 continues to convey the PCB board, the PCB board is sent to the bottom end of the adsorber 83. The adsorber 83 is an adsorption device similar to a vacuum adsorption pump. The output end of the No. 2 electric cylinder 82 drives the adsorber 83 to adsorb the PCB board with the quality problem. Then the No. 2 electric cylinder 82 pushes the PCB board to the bottom end. The B board is adsorbed and sorted out, and the No. 2 electric slider 81 drives the adsorbed PCB board away from the conveyor 61, which plays a role in sorting out the PCB boards with quality problems; after the PCB boards with quality problems are sorted out, the temporary storage box 9 is installed on the side of the conveyor 61, and the No. 2 electric cylinder 82 cooperates with the absorber 83 to suck out the PCB boards with quality problems, and the No. 2 electric slider 81 drives the PCB boards with quality problems to slide to the top of the temporary storage box 9, and then the absorber 83 releases the PCB board, and the PCB board falls into the interior of the temporary storage box 9, and the anti-drop component prevents the PCB from falling, which plays a role in collecting the PCB boards with quality problems. The function of temporary storage: when temporarily storing PCB boards with quality problems, the No. 2 electric cylinder 82 drives the PCB board adsorbed by the absorber 83 to extend to the support slide 91 and close to it. The absorber 83 releases the PCB board and makes it fall into the temporary storage box 9. The PCB board with quality problems will fall directly on the top of the support slide 91. Due to the weight of the PCB board, every time a PCB board is stacked on the support slide 91, the support slide 91 will press down the spring under gravity to contract. The support of the spring can shorten the telescopic distance of the No. 2 electric cylinder 82, accelerate the reset speed of the absorber 83, and the spring can play a buffering role when the PCB board is lowered.
