[0048] The conveying end of the conveying device 3 sequentially passes through the distributing device 1 and the supplementary coating device 2, for sequentially conveying the wood board to the distributing device 1 and the supplementary coating device 2.

[0049] The distributing device 1 is provided with a distributor 11 for applying wood auxiliary agent to the surface of the wood board.

[0050] The supplementary coating device 2 comprises a rotating arm 21, a supplementary coating clamp 22, a stacking platform 23, a supplementary coating platform 24 and a rotating driving mechanism 25.

[0051] The rotating arm 21 is angularly rotatably installed on the conveying device 3, the supplementary coating clamp 22 is installed on the rotating arm 21 for clamping the wood board, the stacking platform 23 is located within the rotation range of the rotating arm 21, and the supplementary coating platform 24 is arranged between the conveying device 3 and the stacking platform 23.

[0053] The scheme provides a wood board coating processing line, which outputs the wood board into the supplementary coating device 2 through the conveying device 3, first uses the distributor 11 to output wood additives to the surface of the wood board, and then outputs the wood board to the supplementary coating device 2.

[0054] Specifically, the conveying device 3 is provided with a conveying end, and can output the wood board to the distributing device 1 and the supplementary coating device 2 in sequence, as long as the wood board is continuously placed on the conveying device; when the wood board is conveyed to the distributing device 1, the distributing device 1 is provided with a distributor 11, which applies wood additives to the surface of the wood board, so that the wood additives are attached to the wood board; the wood additives can be conventional in the wood industry, such as wood glue, wood preservatives, wood mothproof agents and the like. When the wood board passes through the distributing device 1, there may be a problem of uneven distribution on the surface of the wood board; for this, the wood board is continuously output to the work station of the supplementary coating device 2; in the initial state, the rotating arm 21 is located at the position of the conveying end of the conveying device 3, and the supplementary coating clamp 22 is arranged on the rotating arm 21; at this time, the supplementary coating clamp 22 can be started, the supplementary coating clamp 22 clamps the wood board, and then the rotating drive mechanism 25 is started; the rotating drive mechanism 25 drives the rotating arm 21 to rotate, which can drive the rotating arm 21 to rotate from the conveying end of the conveying device 3 to the stacking table 23, so as to drive the wood board of the rotating arm 21 to rotate to the stacking table 23 for stacking; and the rotating arm 21 can pause the rotating drive mechanism 25 between the conveying end of the conveying device 3 and the stacking table 23, so as to make the rotating arm 21 stay in the inclined state between the conveying end of the conveying device 3 and the stacking table 23, so as to make the wood board be placed in the inclined state before stacking; since the supplementary coating platform 24 is arranged between the side of the conveying device 3 and the stacking table 23, the worker on the supplementary coating platform 24 can visually inspect the wood board and repair the defects on the wood board, and can also spray wood additives to the missed areas; thereafter, the rotating drive mechanism 25 can be continuously started, the rotating drive mechanism 25 drives the rotating arm 21 to rotate, so that the wood board rotates to the stacking table 23, so that the wood board is finally stacked on the stacking table 23. When a plurality of wood boards are stacked on the stacking table 23, the discharging process is automatically performed, and the wood boards on the stacking table 23 can be directly transferred.

[0055] The conveying device 3 is a mechanism with a moving function, such as a conveying belt device, a conveying roller device, a moving trolley, a mechanical hand, etc., which can be a single mechanism or multiple mechanisms connected in sequence, as long as the wood board can be conveyed; the rotating driving mechanism 25 is a mechanism with a rotating function, such as a motor, a combination of a motor and a speed reducer, a gear, a gear chain and a motor, etc., as long as the rotating arm 21 can be flipped.

[0056] The rotating arm 21 is provided with a wood board supporting plane 211, the rotating arm 21 is rotated to make the wood board supporting plane 211 below the conveying end of the conveying device 3, the wood board is supported by the wood board supporting plane 211; the fixed end of the rotating arm 21 is connected to the rotating driving mechanism 25; the rotating end of the rotating arm 21 is provided with the supplementary coating clamp 22; the clamping end of the supplementary coating clamp 22 is close to or away from the fixed end of the rotating arm 21, so that the clamping end clamps or releases the wood board.

[0057] The rotating arm 21 of the present scheme not only needs to make the wood board inclined to the outside, but also needs to flip the wood board 180° to the stacking table 23, and more needs to facilitate clamping the wood board by the supplementary coating clamp 22 before and after flipping; for this, the rotating arm 21 of the present scheme is provided with a wood board supporting plane 211, in the initial state, the wood board supporting plane 211 is below the conveying end of the conveying device 3, at this time, the conveying end of the conveying device 3 can normally convey the wood board; when the wood board is conveyed to the work position of the supplementary coating device 2, the rotating driving mechanism 25 can be started, at this time, the bottom surface of the wood board is above the wood board supporting plane 211; at this time, the supplementary coating clamp 22 at the rotating end of the rotating arm 21 can be started, the clamping end of the supplementary coating clamp 22 is moved to the fixed end of the rotating arm 21, so as to be clamped on the side of the wood board away from the rotating driving mechanism 25; the rotating driving mechanism 25 is started, the wood board is lifted and flipped by the wood board supporting plane 211; when the wood board is about to be stacked on the stacking table 23, the wood board is flipped close to 180° (actually slightly less than 180°), when the wood board reaches the stacking table 23, the wood board supporting plane 211 is above the wood board; at this time, only needs to make the clamping end of the supplementary coating clamp 22 away from the fixed end of the rotating arm 21, so as to place the wood board on the stacking table 23 under the action of gravity; thus, this embodiment can realize the wood board unobstructed feeding.

[0058] The supplementary coating clamp 22 includes a clamp driving device 221 and an L-shaped clamping plate 222.

[0059] The clamp driver 221 is installed on the rotating arm 21; the output end of the clamp driver 221 is connected to the L-shaped clamping plate 222, which is used to drive the L-shaped clamping plate 222 to move along the length direction of the rotating arm 21; the L-shaped clamping plate 222 and the supporting plate plane 211 form a U-shaped clamping groove 271, and the opening of the U-shaped clamping groove 271 faces the fixed end of the rotating arm 21; the U-shaped clamping groove 271 is close to or away from the fixed end of the rotating arm 21, which is used to clamp or release the wood board.

[0060] The clamp driver 221 is used to drive the L-shaped clamping plate 222 to move along the length direction of the rotating arm 21; the position of the L-shaped clamping plate 222 on the rotating arm 21 and the supporting plate plane 211 form a U-shaped clamping groove 271, which can be used to clamp the wood board through the opening, so as to make full use of the space position of the supporting plate plane 211; at the same time, the opening of the U-shaped clamping groove 271 faces the fixed end of the rotating arm 21, and the moving distance required for clamping or releasing the wood board is short, so that the wood board can be quickly clamped or released; further, the U-shaped clamping groove 271 only needs to move a small distance away from the fixed end of the rotating arm 21 to quickly release the wood board, which is very suitable for the scene that the wood board is about to be stacked on the stacking table 23, that is, the waiting time before the wood board is lowered is short, the wood board can be quickly stacked on the stacking table 23, and the wood board is stacked more regularly.

[0061] Optimally, the supplementary coating clamp 22 further comprises a longitudinal positioning seat 223.

[0062] The longitudinal positioning seat 223 is installed on the supporting plate plane 211 and close to the fixed end of the rotating arm 21.

[0063] The L-shaped clamping plate 222 of the scheme can move to the fixed end of the rotating arm 21, and when the L-shaped clamping plate 222 is about to clamp the side of the wood board, the L-shaped clamping plate 222 can also move to the longitudinal positioning seat 223, so as to push the wood board to the longitudinal positioning seat 223 and make the wood board abut against the longitudinal positioning seat 223, thereby positioning the wood board on the rotating arm 21. The rotating arm 21 accurately turns the wood board by 180° and stacks the wood board on the stacking table 23.

[0064] Optimally, the supplementary coating device 2 further comprises a transverse positioning arm 26, a transverse positioning driver 27 and a transverse positioning pushing piece 28.

[0065] A pair of transverse positioning arms 26 are arranged on the same side of the conveying device 3, and the rotating arm 21 rotates to pass through the area between the two transverse positioning arms 26.

[0066] The lateral positioning driver 27 is installed on the lateral positioning arm 26, and the output end of the lateral positioning driver 27 is connected to the lateral positioning pusher 28, which is used to drive the lateral positioning pusher 28 to move towards the other lateral positioning arm 26, and to push the wood board on the rotating arm to move.

[0067] The longitudinal positioning seat 223 is used to position the wood board in the longitudinal direction (specifically, perpendicular to the wood board conveying direction) on the rotating arm 21, and the lateral positioning pusher 28 is used to position the wood board in the lateral direction (specifically, perpendicular to the direction of the rotating arm 21); the rotating arm 21 stays at an inclined angle within the rotating range, which can be parallel to the two lateral positioning arms 26; at this time, the lateral positioning driver 27 can be started to drive the lateral positioning pusher 28 to move towards the other lateral positioning arm 26, so as to push the wood board against the lateral positioning pusher 28 of the other lateral positioning arm 26, and the wood board can be adjusted between the two lateral positioning pushers 28 as needed, so as to position the wood board in the lateral direction on the rotating arm 21.

[0068] Optimally, the rotating driving mechanism 25 comprises a rotating base 251, a synchronous rotating shaft 252 and a rotating driver 253.

[0069] The synchronous rotating shaft 252 is rotatably installed on the rotating base 251; the fixed ends of the pair of rotating arms 21 are installed on the synchronous rotating shaft 252, and the output end of the rotating driver 253 is connected to the synchronous rotating shaft 252, which is used to drive the synchronous rotating shaft 252 to rotate, thereby driving the synchronous rotating shaft 252 to rotate synchronously.

[0070] A single synchronous rotating shaft 252 can simultaneously install two rotating arms 21; when it is needed to drive the rotating arm 21 to rotate, only the rotating driver 253 needs to be started to drive the synchronous rotating shaft 252 to rotate, thereby driving the two rotating arms 21 on the synchronous rotating shaft 252 to rotate, and the rotating arm 21 rotates between the conveying end of the conveying device 3 and the stacking table 23.

[0071] As Figure 1 The rotating driver 253 comprises a motor, a gear and a toothed chain; the gear is installed on the motor and the synchronous rotating shaft 252 respectively, and the toothed chain connects the two gears; the motor directly drives the gear to rotate, thereby driving the synchronous rotating shaft 252 to rotate, and thereby driving the rotating arm 2 to rotate by any angle.

[0072] Optimally, the wood board conveying device 3 further comprises a feeding device 4.

[0073] The feeding device 4 comprises a wood board placing rack 41 and a first feeding mechanical arm 42.

[0074] The board placing rack 41 is used for placing the wood board, and the first feeding manipulator 42 is used for transferring the wood board of the board placing rack 41 to the conveying end of the conveying device 3.

[0075] The feeding device 4 is used for continuously inputting the wood board to the conveying end of the conveying device 3, and can realize the function of automatic feeding. Specifically, the first feeding manipulator 42 which can move at any angle is used for grabbing the wood board from the board placing rack 41, placing the wood board on the conveying end of the conveying device 3 after moving adjustment, and transferring the wood board to the distribution device 1 and the coating device 2 by the conveying end of the conveying device 3.

[0078] The scheme can select the travel of the wood board according to whether the wood board needs to be distributed with the wood material aid. When the wood board needs to be distributed with the wood material aid, the feeding device 4, the distribution device 1, the coating platform 24 and the stacking platform 23 can be selected. When the wood board does not need to be distributed with the wood material aid, the wood board can be directly grabbed by the second feeding manipulator 43 and stacked on the stacking platform 23. Specifically, the conveying end of the feeding moving device 44 can move between the board placing rack 41 and the stacking platform 23, and can drive the second feeding manipulator 43 to move. The second feeding manipulator 43 which can move at any angle can grab the wood board and place the wood board on the stacking platform 23 after moving. Further, the scheme can also assemble the wood board distributed with the wood material aid and the wood board not distributed with the wood material aid.

The roller surface of the distribution roller 13 contacts the surface of the wood board. The distributor 11 is installed in the distribution machine box 12 and is used for outputting the wood material aid to the roller surface of the distribution roller 13.

[0081] The wood material assisting agent is mainly applied on the distributing machine box 12, and the conveying end of the conveying device 3 passes through the distributing machine box 12; when the wood board passes through the distributing machine box 12, the distributing roller 13 can contact the surface of the wood board, the distributor 11 continuously outputs the wood material assisting agent to the roller surface of the distributing roller 13, so that the surface of the distributing roller 13 is attached with the wood material assisting agent, and finally the wood material assisting agent is attached to the surface of the wood board under the rotation of the distributing roller 13, so that the wood material assisting agent is uniformly applied on the surface of the wood board.
