DETAILED DESCRIPTION

[0020] The following Figures 1-4 The application is further described in detail.

[0021] The embodiment of the application discloses a surface treatment equipment of a needle type backboard. Referring to Figure 1 and Figure 2 , the surface treatment equipment of the needle type backboard comprises a machine body 1 and a conveying belt 2 mounted on the machine body 1, a spraying area 3 is formed in the machine body 1, and the conveying belt 2 passes through the spraying area 3 on the machine body 1, so that the needle type backboard is conveyed to the spraying area 3 by the conveying belt 2 for spraying treatment.

[0022] Referring to Figure 1 and Figure 2 , a plurality of mounting plates 15 are arranged on the top wall of the spraying area 3, the mounting plates 15 are in one-to-one correspondence with the connecting columns in one row on the surface of the needle type backboard, the plurality of mounting plates 15 are located above the conveying belt 2, the arrangement direction of the plurality of mounting plates 15 is perpendicular to the conveying direction of the conveying belt 2, and each mounting plate 15 is rotationally arranged in a vertical direction and is provided with a mounting ring 4, so that the mounting ring 4 is in one-to-one correspondence with the mounting plate 15, and the mounting ring 4 is located above the conveying belt 2.

[0023] Referring to Figure 2 and Figure 3, specifically, the upper surface of the mounting ring 4 is relatively fixed with two hangers 18, and the two hangers 18 are slidingly connected with the lower surface of the mounting plate 15 along the center of the mounting ring 4, realizing the rotating connection between the mounting ring 4 and the corresponding mounting plate 15, so that the mounting ring 4 and the corresponding mounting plate 15 will not fall off. Each mounting ring 4 is slidingly provided with a mounting block 5, and the sliding direction of the mounting block 5 is perpendicular to the rotating axis of the mounting ring 4. The mounting block 5 is fixed with a guide rod 16, and the length direction of the guide rod 16 is parallel to the sliding direction of the mounting block 5. The guide rod 16 is slidingly arranged on the corresponding mounting ring 4, and the sliding cooperation of the guide rod 16 and the mounting ring 4 helps to guide the sliding of the mounting block 5. The mounting block 5 is ball-jointed with a mounting ball 6, and specifically the mounting ball 6 is rollingly arranged on the mounting block 5, and the opposite ends of the mounting ball 6 are located outside the mounting block 5. The mounting ball 6 is fixedly provided with a spray gun 7, and the spray gun 7 is communicated with an external paint source through a hose 19. The spraying area 3 is provided with a rotating member for driving the mounting ring 4 to rotate. The mounting ring 4 is provided with a moving member for driving the mounting block 5 to slide towards the center of the corresponding mounting ring 4. The mounting block 5 is provided with an adjusting assembly for adjusting the angle of the spray gun 7.

[0024] In use, the pin back plate is placed on the conveying belt 2, so that the connecting columns in the same row on the pin back plate are aligned with the plurality of mounting rings 4 one by one. The pin back plate is conveyed to the lower side of the spray gun 7 by the conveying belt 2. At this time, the mounting block 5 is located at the center of the corresponding mounting ring 4, and the spray gun 7 is in a vertical state. The pin back plate gradually passes under the plurality of spray guns 7 to be sprayed with paint. When the connecting column of the pin back plate moves to the center of the mounting ring 4 at the corresponding position, the conveying belt 2 stops conveying. The mounting block 5 drives the spray gun 7 to move to the required position by moving away from the center of the corresponding mounting ring 4 through the moving member. The outlet of the spray gun 7 is adjusted to tilt towards the center of the mounting ring 4 through the adjusting assembly, so that the spray gun 7 is tilted and aligned around the connecting column at the corresponding position. Then the mounting ring 4 drives the mounting block 5 to rotate along the center of the mounting ring 4 through the rotating member. The spray gun 7 tilts and sprays along the circumference of the connecting column, thereby helping to cover the surface around the connecting column, improving the spraying effect around the connecting column of the pin back plate, and to some extent ensuring the quality of the surface treatment of the pin back plate.

[0025] Then the conveying belt 2 continues to convey, the mounting block 5 drives the spray gun 7 to move to the center position by moving towards the center of the corresponding mounting ring 4 through the moving member. The outlet of the spray gun 7 is adjusted to tilt away from the center of the mounting ring 4 through the adjusting assembly, so that the spray gun 7 remains in a vertical state. The above steps are repeated until the pin back plate is moved out of the spraying area 3 by the conveying belt 2.

[0026] Referring to Figure 2, for the case that the adjacent connection columns in the same row on the pin backboard are close, the spacing between the adjacent installation plates 15 is set as small as possible to ensure that the spraying range of the adjacent spray guns 7 can completely cover the surface of the pin backboard between the adjacent connection columns. For the case that the adjacent connection columns in the same row on the pin backboard are far apart, a spray gun 7 arranged vertically between the adjacent installation plates 15 can be added to ensure that the spraying range of the spray gun 7 can completely cover the surface of the pin backboard between the adjacent connection columns.

[0027] With reference to Figure 2 and Figure 3 In order to facilitate the movement of the installation block 5 towards the direction close to or away from the center of the corresponding installation ring 4, the moving part includes an electric push rod 11, which is in one-to-one correspondence with the installation ring 4, is fixedly installed on the corresponding installation ring 4, and has an extension direction parallel to the sliding direction of the corresponding installation block 5. The electric push rod 11 is located on the side of the corresponding installation block 5 away from the guide rod 16, and the installation block 5 is connected with the moving end of the corresponding electric push rod 11. By starting the electric push rod 11, the electric push rod 11 can drive the installation block 5 to move with the spray gun 7, so as to adjust the position of the spray gun 7 and facilitate the spraying of the area around the connection column on the pin backboard.

[0028] With reference to Figure 3 and Figure 4 In order to facilitate the adjustment of the angle of the spray gun 7 on the installation block 5, the adjusting assembly includes a circular-arc elastic sheet 8 and a pushing part. The circular-arc elastic sheet 8 is located above the installation block 5, one end of the circular-arc elastic sheet 8 is fixedly arranged on the installation block 5, and the other end is fixedly arranged on the installation ball 6. The circular-arc elastic sheet 8 is convex towards the connecting part between the installation ball 6 and the installation block 5. When the circular-arc elastic sheet 8 is in a natural state, the spray gun 7 is in a vertical state. In other embodiments, the circular-arc elastic sheet 8 can be replaced by a spring, which is sleeved on the upper end of the installation ball 6. One end of the spring is fixed on the installation block 5, and the other end is fixed on the installation ball 6. By the spring, the installation ball 6 can also be kept in an initial state and can be reset after rotation.

[0029] With reference to Figure 3 and Figure 4 The pushing part is arranged on the installation ring 4 and is used to tilt the outlet of the spray gun 7 towards the center of the installation ring 4 when the installation block 5 moves towards the direction away from the center of the corresponding installation ring 4. Specifically, the pushing part includes an abutting rod 9 arranged on the installation ring 4. The length direction of the abutting rod 9 is parallel to the sliding direction of the corresponding installation block 5. The abutting rod 9 is located on the side of the installation block 5 close to the corresponding electric push rod 11 and is located below the installation block 5.

When the installation block 5 moves towards the direction away from the center of the installation ring 4, the installation block 5 is close to the corresponding abutting rod 9.

[0030] When the mounting block 5 moves towards the direction away from the mounting ring 4, the spray gun 7 gradually approaches the corresponding abutting rod 9, and with the continuous movement of the mounting block 5, the abutting rod 9 abuts against the corresponding spray gun 7, then the mounting block 5 continues to move, the abutting rod 9 pushes the spray gun 7 to drive the mounting ball 6 to rotate in the mounting block 5 by a certain angle, drives the deformation of the circular-arc elastic sheet 8, and makes the outlet of the spray gun 7 deviate towards the center of the corresponding mounting ring 4 until the spray gun 7 deviates to the required angle and is aligned with the surrounding of the connecting column at the corresponding position on the needle backboard, thereby helping to adjust the angle and spray the connecting column position, helping to improve the spraying effect and ensure the spraying quality of the needle backboard.

[0031] With reference to Figure 3 and Figure 4 , one end of the abutting rod 9 close to the spray gun 7 is fixed with a circular-arc abutting plate 10, the circular-arc abutting plate 10 is convex towards the side away from the corresponding spray gun 7, and the circular-arc abutting plate 10 is used for abutting against the spray gun 7. By abutting the circular-arc abutting plate 10 against the spray gun 7, the spray gun 7 is not easy to be impacted and separated from the abutting rod 9 during spraying, and the circular-arc abutting plate 10 can better abut against the spray gun 7, so that the spray gun 7 does not shake too much during the spraying process.

[0032] With reference to Figure 3 and Figure 4 , the abutting rod 9 is slidably arranged on the mounting ring 4, and the sliding direction of the abutting rod 9 is parallel to the sliding direction of the mounting block 5. The mounting ring 4 is provided with a fixing member for relatively fixing the abutting rod 9 and the mounting ring 4. Specifically, the fixing member includes a bolt threaded through the bottom wall of the mounting ring 4, and the bolt is used for abutting cooperation with the abutting rod 9. In other embodiments, the bolt can be replaced by a screw, a rivet or the like.

[0033] By rotating the bolt, the bolt is separated from the abutting rod 9, the abutting rod 9 can be slid towards or away from the center of the corresponding mounting ring 4 as needed, so as to adjust the deviation angle of the spray gun 7 on the mounting block 5; by rotating the bolt, the bolt abuts against the abutting rod 9, so that the abutting rod 9 is relatively fixed with the mounting ring 4.

[0034] With reference to Figure 2 and Figure 3To facilitate the rotation of the mounting ring 4, the rotating member includes a belt wheel 12, a transmission wheel 13 and a driving source 14, the belt wheel 12 is fixedly sleeved on the mounting ring 4, the transmission wheel 13 is rotationally arranged on the top wall of the spraying area 3, the transmission wheel 13 is located on the same straight line as the plurality of belt wheels 12, the transmission belt 17 is wound between the transmission wheel 13 and the plurality of belt wheels 12, the transmission wheel 13 and the plurality of belt wheels 12 are drivingly connected through the transmission belt 17, and the driving source 14 is arranged in the spraying area 3. The driving source 14 is used to drive the transmission wheel 13 to rotate. Specifically, the driving source 14 adopts a servo motor, the servo motor is installed on the top wall of the spraying area 3, the transmission wheel 13 is coaxially connected with the output shaft of the servo motor, and in other embodiments, the driving source 14 can also adopt a stepping motor, a driving motor and the like.

[0035] When it is necessary to drive the mounting ring 4 to rotate, the driving source 14 is started, the driving source 14 drives the transmission wheel 13 to rotate, the transmission wheel 13 drives the plurality of belt wheels 12 to rotate through the transmission belt 17, so as to realize that the belt wheel 12 drives the mounting ring 4 to rotate, so as to facilitate the mounting ring 4 to drive the spray gun 7 to rotate to spray around the connecting column. In order to avoid the hose 19 from being wound, the mounting ring 4 rotates one circle each time, and then reversely rotates one circle next time.

[0036] With reference to Figure 2 , the mounting plate 15 is detachably arranged on the top wall of the spraying area 3 by means of bolts, screws, rivets and the like, so that the number of spray guns 7 can be increased or reduced and the position of the mounting ring 4 can be adjusted according to needs, so as to spray the needle type backboard of different sizes, and the application range is expanded.

[0037] With reference to Figure 1 , Figure 2 and Figure 3 , in order to realize intelligent processing, the controller can be installed on the machine body 1, and the transmission belt 2, the electric push rod 11 and the driving source 14 are all wirelessly connected with the controller.
