[0073] The following will detail a PCB board printing device of the present application through the following embodiments.

[0074] In this embodiment, as Figures 1 to 6 shown, the PCB board printing device includes: a bearing member 1, provided with a plurality of support assemblies 101, the plurality of support assemblies 101 are arranged in the vertical direction, and each support assembly 101 is used to support the PCB board;

The first transfer mechanism 6 is fixed at one end of the first conveying mechanism 4 close to the carrier 1, and the second transfer mechanism 7 is fixed at one end of the second conveying mechanism 5 close to the carrier 1. During use, the first transfer mechanism 6 places the PCB boards conveyed by the first conveying mechanism 4 on each support assembly 101 respectively. Then the lifting mechanism 2 lowers the carrier 1 into the first reaction tank 3 for electroplating for a period of time. Then the lifting mechanism 2 drives the carrier 1 to move up. Finally, the electroplated PCB boards are placed on the second conveying mechanism 5 through the second transfer mechanism 7. During the process of the first transfer mechanism 6 and the second transfer mechanism 7 picking up and placing the PCB boards, the height of the carrier 1 is adaptively adjusted synchronously through the lifting mechanism 2.

[0083] In some technical solutions, the conveying rollers of the first conveying mechanism 4 and the second conveying mechanism 5 are arranged in a form of one thick section and one thin section.

[0084] In other technical solutions, a number of through holes are provided on the front and back sides of the carrier 1, so that the liquid in the first reaction tank 3 can move through the front and back sides of the carrier 1 to between each support assembly 101.

[0085] In this embodiment, the lifting mechanism 2 includes:

[0086] The first lifting mechanism 201, the second lifting mechanism 202, the third lifting mechanism 203, and the fourth lifting mechanism 204 are all connected to the carrier 1;

[0088] The fourth lifting mechanism 204 is symmetrically arranged relative to the second lifting mechanism 202 and the third lifting mechanism 203.

[0089] In this technical solution, the first lifting mechanism 201, the second lifting mechanism 202, the third lifting mechanism 203, and the fourth lifting mechanism 204 all include a driving motor, a winding wheel, and a flexible rope. The driving motor is fixed on the slider of the third conveying mechanism 14, the winding wheel is fixed on the rotating shaft of the driving motor, one end of the flexible rope is wound and fixed on the winding wheel, and the other end is fixed on the top surface of the carrier 1. The first lifting mechanism 201 and the second lifting mechanism 202 are symmetric left and right, the first lifting mechanism 201 is on the left, and the second lifting mechanism 202 is on the right; the first lifting mechanism 201 and the third lifting mechanism 203 are symmetric front and back, the first lifting mechanism 201 is in the front, and the third lifting mechanism 203 is in the back; the third lifting mechanism 203 and the fourth lifting mechanism 204 are symmetric left and right, the third lifting mechanism 203 is on the left, and the fourth lifting mechanism 204 is on the right; the second lifting mechanism 202 and the fourth lifting mechanism 204 are symmetric front and back, the second lifting mechanism 202 is in the front, and the fourth lifting mechanism 204 is in the back.

[0090] By controlling the winding and unwinding differences of the first lifting mechanism 201, the second lifting mechanism 202, the third lifting mechanism 203, and the fourth lifting mechanism 204, the carrier 1 can be tilted forward, to the left, to the right, or backward relative to the first reaction tank 3; by synchronously controlling the first lifting mechanism 201, the second lifting mechanism 202, the third lifting mechanism 203, and the fourth lifting mechanism 204, the carrier 1 can move vertically up and down.

[0091] In this embodiment, it further includes:

[0092] The first limiting mechanism 8 is arranged on the first side of the carrier 1 and is used to adjust the size of the opening on the first side of the carrier 1;

[0093] The second limiting mechanism 9 is arranged on the second side of the carrier 1 and is used to adjust the size of the opening on the second side of the carrier 1.

[0094] In this technical solution, the first limiting mechanism 8 is arranged on the left side of the carrier 1, and the second limiting mechanism 9 is arranged on the right side of the carrier 1. By setting the first limiting mechanism 8 and the second limiting mechanism 9, the passing width in the front-back direction on both the left and right sides of the carrier 1 can be adjusted, so that when the PCB is buoyed by the liquid in the first reaction tank 3, it will not slide outside the carrier 1, and the PCB can be released when the transfer mechanism picks up and places the PCB board.

[0095] In this embodiment, the first limiting mechanism 8 includes:

[0096] A plurality of stoppers 801, the plurality of stoppers 801 are arranged in the vertical direction, each stopper 801 is correspondingly arranged with each support assembly 101, each stopper 801 is hinged to the carrier 1, and each stopper 801 is provided with a guiding hole;

[0099] A guiding member 805, arranged on the carrier 1 and abutted against the winding rope 802.

[0100] In this technical solution, the stopper 801 is rotatably arranged on the left front side of the carrier 1 through a horizontally left-right pin shaft. When the stopper 801 is in the front-back horizontal state, the front end of the stopper 801 extends to the front side of the carrier 1, and the rear end of the stopper 801 extends to the left side surface of the carrier 1. The weight of the front end of the stopper 801 is greater than the weight of the rear end of the stopper 801, so that the stopper 801 has the potential energy of automatically rotating downward at the front end when not affected by the winding rope 802. The winding mechanism 804 includes a motor and a rotating wheel. The rotating wheel is fixed on the motor rotating shaft. The top end of the winding rope 802 is wound and fixed on the rotating wheel of the winding mechanism 804. The guiding member 805 is a guiding wheel arranged on the left front side of the top surface of the carrier 1, and the guiding member 805 makes the part of the winding rope 802 extending downward tend to be vertically arranged. The protrusion 803 is a hard convex block uniformly fixed on the winding rope 802. The front end parts of each stopper 801 are provided with strip-shaped guiding holes penetrating up and down and extending front and back. The winding rope 802 passes through the guiding holes of each stopper 801, and the top surfaces of each protrusion 803 are respectively abutted against the bottom surfaces of each stopper 801.

[0101] The description is made when the stopper 801 is in the front-rear horizontal position. At this time, the left side surface of the carrier 1 is blocked by the rear ends of the respective stoppers 801. At this time, the PCB board is restricted within the carrier 1. By unwinding and winding the winding rope 802 through the winding mechanism 804, the winding rope 802 rotates downward under the action of the gravity at the front ends of the respective stoppers 801, so that the distance that the stopper 801 extends to the left side surface of the carrier 1 becomes shorter, and gaps appear between the connected stoppers 801. At this time, the transfer mechanism can pick up and place the PCB board; after the picking and placing action is completed, the winding mechanism 804 is activated to drive the winding rope 802 to wind a certain length, so that the respective stoppers 801 are horizontal under the action of the respective protrusions 803, and can extend to the left side surface of the carrier 1 again to block the PCB board.

[0102] In some technical solutions, the second limiting mechanism 9 has the same structure as the first limiting mechanism 8 and is arranged symmetrically left and right.

The angles at which the two front and rear symmetric winding ropes 802 enter the winding mechanism 804 are different, so that the winding mechanism 804 can wind or unwind the two front and rear winding ropes 802 synchronously.

[0104] In this embodiment, the first limiting mechanism 8 further includes:

[0105] Springs 806, respectively connected to the winding rope 802 and the carrier 1.

[0106] In this technical solution, the springs 806 are vertically fixed at the bottom of the carrier 1, and the top ends of the springs 806 are fixedly connected to the winding rope 802 or the lowermost protrusion 803. The arrangement of the springs 806 makes the part of the winding rope 802 between the guiding member 805 and the springs 806 in a tensioned state, and can also promote the rotation of the stopper 801.

[0107] In some technical solutions, the springs 806 are replaced with elastic members such as elastic ropes.
