[0027] The following is a detailed description of a preferred embodiment of the present utility model in conjunction with the accompanying drawings.

[0028] Referring to Figures 1 to 5 , the reflector cup and PCB board assembly device provided by the present utility model includes a workbench 1, a placing table 2 provided on the workbench 1, a limiting groove 21 for placing the reflector cup 3 provided on the placing table 2, and a flap 4, a top plate 5, and an anti-fooling cylinder 6 are further provided on the workbench 1.

[0029] One side of the flap 4 is hinged to the workbench 1 so that the flap 4 can be turned over and closed on the placing table 2. Specifically, two supports 8 are arranged at intervals along the length direction of the workbench 1 beside the placing table 2, and hinge shafts 42 rotatably connected to the supports 8 are respectively arranged at both ends of one side of the flap 4. In addition, two stoppers 10 for limiting the opening angle of the flap 4 are arranged between the two supports 8. The two stoppers 10 are arranged at intervals, and a support inclined surface 101 is arranged at the upper end of the side of the stopper 10 facing the placing table 2. Thus, the flap 4 has a unified opening angle, and at the same time, the support contact surface between the stopper 10 and the flap 4 is increased by the arranged support inclined surface 101, so that the flap 4 is stably supported.

[0030] The top plate 5 is movably arranged on the side of the flap 4 away from the placing table 2, and a pressing block 51 is arranged on the side of the top plate 5 facing the flap 4. A through slot hole 41 adapted to the pressing block 51 is arranged on the flap 4. A plurality of vacuum suction cups 52 are arranged on the pressing block 51, and the vacuum suction cups 52 can adsorb the PCB board 7 and place it in the through slot hole 41. In addition, a plurality of springs 12 and guide shafts 13 are arranged between the flap 4 and the top plate 5. The plurality of guide shafts 13 are arranged close to the outer peripheral wall of the flap 4. One end of the guide shaft 13 is fixed on the top plate 5, and the other end is slidably connected to the flap 4 through a linear bearing 131. Specifically, when the flap 4 is in the open state, the vacuum suction cups 52 are ventilated to adsorb the PCB board 7 thereon. Thus, when the flap 4 is turned over and closed on the placing table 2, the PCB board 7 is driven to turn downward synchronously. The top plate 5 presses downward to drive the PCB board 7 to vertically press on the reflector cup 3 on the placing table 2, so as to realize the assembly of the reflector cup 3 and the PCB board 7. In addition, since the vacuum suction cups 52 are horn-shaped structures made of rubber materials, during the downward pressing process of the top plate 5, the vacuum suction cups 52 form a certain buffer, thereby preventing the vacuum suction cups 52 from damaging the product. Moreover, through the guide shafts 13 and springs 12 between the top plate 5 and the flap 4, the top plate 5 can press downward vertically to ensure the unity of the position of the PCB board and guarantee the assembly quality.

[0031] In addition, a plurality of probes 53 are further arranged on the side of the pressing block 51 facing the vacuum suction cups 52. The probes 53 are fixedly arranged on the pressing block 51 through probe fixing seats 54, and the plurality of probes 53 are respectively arranged close to the edge of the pressing block 51. The probes 53 are used to detect whether there is a reflector cup 3 on the placing table 2 and at the same time detect whether the reflector cup is placed in place. That is, when the flap 4 is closed on the placing table 2, if the probes 53 detect that there is no reflector cup 3 placed in the placing table 2, or there is a deviation between the distances detected by the probes 53, a signal is transmitted to the control unit in the control box body. Then, at this time, the top plate 5 will not press downward; so as to avoid damaging the reflector cup 3 or the PCB board.

[0032] Further, the anti-fooling air cylinder 6 is arranged on one side close to the hinged end of the flap 4. When the flap 4 covers the placement table 2, the piston rod 61 of the anti-fooling air cylinder 6 extends vertically upward to the upper surface of the top plate 5. That is, when the device is in the assembled state (i.e., when the top plate is in the working state of pressing down), the piston rod 61 of the anti-fooling air cylinder 6 extends, and the side wall of the top plate 4 close to the piston rod 61 abuts against the outer peripheral surface of the piston rod 61, thereby restricting the flipping and opening of the flap 4; when in the completed assembled state (i.e., when the top plate is reset), the piston rod 61 of the anti-fooling air cylinder 6 retracts, so that the flap 4 can be opened. The flap 4 is provided with an avoidance groove 43 on the side facing the anti-fooling air cylinder 6, so that when the flap 4 is fully opened, the anti-fooling air cylinder 6 will not interfere with the flap 4. The setting of the anti-fooling air cylinder ensures the effectiveness of the top plate's movement, avoiding the flap from being accidentally opened due to insufficient pressing distance of the top plate, which affects the assembly quality.

[0033] Further, a program box body 15, a solenoid valve 16 and a leg 17 are provided at the bottom of the workbench 1. The program box body 15 and the leg 17 are respectively arranged at both ends of the bottom of the workbench 1; the program box body 15 is provided with a power access terminal 151 and a pneumatic switch 152. It can be understood that the solenoid valve 16 is used to adjust parameters such as air pressure; arranging a control program for controlling the action relationship between various components in the control box body 15 belongs to the conventional technology in the art and will not be elaborated here.

[0034] A pressure display meter 18 is provided at one end of the workbench 1 close to the program box body 15. That is, when the pressure of the top plate 5 reaches the set value, the vacuum suction cup air source is closed, and at this time, the assembly operation is completed. In addition, a second microswitch 14 for detecting the pressing state of the top plate 5 is also provided on the workbench 1. The top plate 5 is provided with a pressing block 55 on the side facing the second microswitch 14. The driving plate of the second microswitch 14 is touched by the pressing block 55 to feed back a signal to the control unit, so as to ensure that when the flap completely covers the placement table, the top plate starts to press down, and it also further ensures that the pressing block is directly above the placement table, ensuring the effectiveness and unity of each action and ensuring the assembly quality.

[0035] In addition, a first microswitch 11 for detecting that the flap 4 is fully opened is provided at one end of a stop block 10 close to its support inclined surface 101.

[0036] In summary, for the reflecting cup and PCB board assembling device provided by the present utility model, the reflecting cup is positioned on the placing table, and the PCB board is adsorbed and positioned on the through slot holes of the turning plate by the vacuum suction cups on the top plate. The turning plate is turned over and covered on the placing table to realize the assembly of the reflecting cup and the PCB board. The anti-fooling cylinder is provided to ensure effective assembly. The structure is simple, and the positioning of the product is unified, thereby improving the assembly consistency and assembly efficiency. By arranging a guiding shaft between the top plate and the turning plate, the top plate can be vertically pressed down, so that the PCB board is vertically pressed on the reflecting cup, ensuring the assembly stability and the position accuracy, and improving the assembly quality. By arranging control components such as a first micro switch, a second micro switch and a solenoid valve, the reliability of the device during operation is ensured.
