Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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. Specific embodiment 1

[0028] In order to address the shortcomings of the existing technology, such as Figure 1-6 As shown, the utility model provides a patch platform device of a patch machine, comprising a feeding mechanism 1 and a PCB board 3, and a holding mechanism 2 for holding the PCB board 3, wherein the holding mechanism 2 comprises a rotating gear 21, wherein the rotating gear 21 is provided with a rack 22 meshing with each other, wherein the rack 22 is fixedly connected with a connecting rod 23, and a holding block 24 is provided below the connecting rod 23;

[0029] The holding block 24 includes a connecting plate 241, and a rubber pad 242 is connected below the connecting plate 241. The connecting plate 241 and the rubber pad 242 are provided with screw holes 243 for fixed connection. Matching fixing screws 244 are provided inside the screw holes 243. The fixing screws 244 are used for fixed connection between the connecting plate 241 and the rubber pad 242.

[0030] The feeding mechanism 1 includes a main transmission wheel 11 and a driven transmission wheel 12, and a transmission belt 13 is arranged between the main transmission wheel 11 and the driven transmission wheel 12; a support plate 14 is arranged below the transmission belt 13; the support plate 14 can cooperate with the holding block 24 in the holding mechanism 2 to hold the PCB board 3;

[0031] The rotating gear 21 is externally connected to a motor, and when the motor is driven, the rotating gear 21 is driven to rotate, and when the rotating gear 21 rotates, the gear racks 22 meshing with each other are driven to move;

[0032] The main transmission wheel 11 is externally connected to a motor, and when the motor is driven, the main transmission wheel 11 is driven to rotate. When the main transmission wheel 11 rotates, the driven transmission wheel 12 is driven to rotate through the transmission belt 13 .

[0033] In summary, the basic working principle of the utility model is as follows: when the patch machine is working, the main transmission wheel 11 in the feeding mechanism 1 is rotated by an externally connected motor, and when the main transmission wheel 11 rotates, the driven transmission wheel 12 is driven to rotate by the arranged transmission belt 13, thereby transmitting the PCB board 3, and when the PCB board 3 reaches the patch area, the motor connected to the main transmission wheel 11 stops rotating, and the PCB board 3 stops the transmission movement, wherein the motor connected to the rotating gear 21 in the pressing mechanism 2 is started, and at this time the motor drives the rotating gear 21 to rotate, and the rotating gear 21 is rotated. The rotation drives the rack 22 to move downward, and at the same time, the holding block 24 moves downward to cooperate with the support plate 14 to fix and hold the PCB board 3, thereby achieving the effect of fixing the PCB board 3 when the placement machine is performing placement. The PCB board 3 is pressed by the holding mechanism 2. When the placement machine is performing high-speed placement on the PCB board 3, the rubber pad 242 set on the holding block 24 can effectively absorb and reduce the high-frequency vibration caused by the vibration of the PCB board 3 caused by the operation of the placement machine by using its own elasticity and damping characteristics.
