[0037] Referring to Figures 1 to 4 , the oiling device of the present utility model includes:

[0038] A machine table 100, on which an oiling station is provided;

[0039] A conveying device 200, which is arranged on the machine table 100 and is used to convey multiple circuit boards from back to front, so that the multiple circuit boards can be sequentially moved to the oiling station;

[0040] A first lifting driving member 110, a top plate 120 and multiple positioning columns 140. The first lifting driving member 110 is arranged at the position corresponding to the oiling station on the machine table 100. The top plate 120 is connected to the output end of the first lifting driving member 110. The multiple positioning columns 140 are all arranged on the top plate 120. The first lifting driving member 110 can drive the top plate 120 to rise, so that the multiple positioning columns 140 respectively pass through the through holes on the circuit board at the oiling station, and the top plate 120 presses and fixes the circuit board on the conveying device 200;

[0041] A moving driving device 300 and an oiling head 310. The output end of the moving driving device 300 is connected to the oiling head 310. The moving driving device 300 is used to drive the oiling head 310 to move in the up-down direction, left-right direction and front-back direction, so that the oiling head 310 can coat the protective oil on the circuit board at the oiling station.

[0042] It can be understood that the conveying device 200 can convey multiple circuit boards to be oiled from the back to the front, so that the multiple circuit boards can move to the oiling station in sequence. When the circuit board moves to the oiling station, the conveying device 200 stops conveying the circuit board, and then the first lifting driving member 110 drives the top plate 120 to rise. A plurality of positioning posts 140 are provided on the top plate 120, and the plurality of positioning posts 140 can rise together with the top plate 120, so that the plurality of positioning posts 140 penetrate into a plurality of through holes on the circuit board. The plurality of positioning posts 140 can respectively abut against the hole walls of the plurality of through holes, so that the plurality of positioning posts 140 play a positioning role for the circuit board, so that the circuit board can accurately stay at the oiling station. As the top plate 120 continues to rise, the top plate 120 can abut against the circuit board, so that the circuit board can be tightly fixed on the conveying device 200 by the top plate 120. Then the moving driving device 300 is started, and the moving driving device 300 can drive the oiling head 310 to move in the up and down direction, left and right direction, and front and back direction, so that the oiling head 310 can apply a layer of white oil on the circuit board at the oiling station. After the circuit board at the oiling station is oiled, the first lifting driving member 110 drives the top plate 120 to descend, so that the top plate 120 releases the circuit board, and the conveying device 200 continues to drive the plurality of circuit boards to move forward, so that the next circuit board moves to the oiling station, and the above process is repeated, so that the oiling head 310 can apply a layer of protective oil on the plurality of circuit boards. This oiling device can quickly apply a layer of protective oil on multiple circuit boards, improving the oiling speed, and thus being beneficial to improving the oiling efficiency of the circuit boards.

[0043] Reference Figure 1 and Figure 7 , the oiling device further includes a mounting plate 320. The number of oiling heads 310 is two. The mounting plate 320 is connected to the output end of the moving driving device 300, and the two oiling heads 310 are both provided on the mounting plate 320. It can be understood that the moving driving device 300 can drive the mounting plate 320 and the two oiling heads 310 on the mounting plate 320 to move in the up and down direction, left and right direction, and front and back direction, so that the two oiling heads 310 can oil the circuit board simultaneously, further improving the oiling efficiency of the circuit board. On the other hand, as an embodiment of the present invention, two oiling stations are provided on the machine table 100, and the two oiling stations are distributed in the front and back direction. The first lifting driving members 110 and the top plates 120 are both two, and the two first lifting driving members 110 are respectively provided at the two oiling stations. The output ends of the two first lifting driving members 110 are respectively connected to the two top plates 120, and a plurality of positioning posts 140 are provided on both of the two top plates 120, that is, the potential plates at the two oiling stations can be tightly clamped simultaneously. The two oiling heads 310 on the mounting plate 320 can respectively oil the circuit boards at the two oiling stations simultaneously, further improving the oiling efficiency of the circuit boards.

[0044] Reference Figure 3 and Figure 4 Figure 4 , a guide frustum 141 is provided at the upper end of the positioning post 140. The guide frustum 141 gradually contracts from bottom to top. The guide frustum 141 can pass through the through hole on the circuit board, so that the positioning post 140 is inserted into the through hole on the circuit board. It can be understood that the guide frustum 141 gradually contracts from bottom to top, and the guide frustum 141 plays a guiding role, enabling the positioning post 140 to be smoothly inserted into the through hole on the circuit board.

[0045] Reference Figure 3 and Figure 4 Figure 4 , the oiling device further includes a plurality of support blocks 130. The plurality of support blocks 130 are all arranged on the top plate 120. The lower ends of the plurality of positioning posts 140 are respectively connected to the plurality of support blocks 130. The plurality of support blocks 130 are all used to abut against the lower surface of the circuit board. A soft pad is provided on the support block 130, and the support block 130 abuts against the lower surface of the circuit board through the soft pad. It can be understood that the first lifting driving member 110 drives the top plate 120 to rise, so that the top plate 120, the plurality of support blocks 130 and the plurality of positioning posts 140 on the top plate 120 approach the circuit board. The guide frustum 141 on the upper end of the positioning post 140 first passes through the through hole on the circuit board, so that the positioning post 140 is inserted into the through hole on the circuit board. As the top plate 120 continues to rise, the plurality of support plates 230 abut against the circuit board, and the circuit board is tightly fixed on the conveying device 200 under the action of the plurality of support blocks 130. A soft pad is provided on the support block 130, and the support block 130 abuts against the circuit board through the soft pad, avoiding scratching the circuit board caused by the support block 130 directly abutting against the circuit board. On the other hand, the soft pad can increase the friction between the support block 130 and the circuit board, which is beneficial to improving the effect of tightly clamping the circuit board.

[0046] Reference Figure 3, the oiling device further includes a second lifting drive member 150 and a baffle 160. The second lifting drive member 150 is provided on the top plate 120, and the output end of the second lifting drive member 150 is connected to the baffle 160. The second lifting drive member 150 can drive the baffle 160 to rise so that the baffle 160 abuts against the rear end of the circuit board at the oiling station. It can be understood that the first lifting drive member 110 drives the top plate 120 to rise, so that the second lifting drive member 150 and the baffle 160 can rise together with the top plate 120. Then the second lifting drive member 150 drives the baffle 160 to rise so that the baffle 160 can abut against the rear end of the circuit board at the oiling station. The baffle 160 plays a limiting role, preventing the circuit board from shaking during the oiling process, enabling the oiling head 310 to accurately apply the protective oil on the circuit board, and being beneficial to improving the oiling accuracy of the oiling head 310. As an embodiment of the present invention, after the baffle 160 rises, it can be located behind the rear end of the circuit board at the oiling station. Then the conveying device 200 drives the circuit board to move backward a small distance so that the circuit board abuts against the baffle 160. The baffle 160 plays a positioning role, enabling the circuit board to be accurately positioned in the front-rear direction at the oiling station. As an embodiment of the present invention, it further includes a third linear drive member and a push plate. The third linear drive member is connected to the top plate 120, and the push plate is connected to the output end of the third linear drive member. The third linear drive member and the push plate can rise together with the top plate 120, enabling the push plate to move to the front of the circuit board. Then the third linear drive member drives the push plate to move backward so that the push plate and the baffle 160 clamp the circuit board, enabling the circuit board to be accurately positioned in the front-rear direction at the oiling station.

[0047] Reference Figure 5 and Figure 6, the conveying device 200 includes two brackets 210 and two conveyor belts 220. The two brackets 210 are both parallel to the front-rear direction. The two conveyor belts 220 are respectively rotatably connected to the two brackets 210.

It can be understood that the two conveyor belts 220 are respectively rotatably connected to the two brackets 210, and the two conveyor belts 220 respectively abut against the left and right ends of the circuit board. When the two conveyor belts 220 rotate, they can drive multiple circuit boards to move from the front to the rear. In the present utility model, the conveying device 200 further includes two support plates 230. The two support plates 230 are respectively arranged on the two brackets 210. The two support plates 230 are respectively arranged in the area surrounded by the two conveyor belts 220. The two support plates 230 respectively support the left and right ends of the circuit board through the two conveyor belts 220. It can be understood that the two support plates 230 both support the left and right ends of the circuit board through the two conveyor belts 220, that is, the two support blocks 130 play a supporting role for the circuit board, ensuring the stability of the circuit board during the movement and oiling processes.

[0048] Reference Figure 2 and Figure 5 , the conveying device 200 further includes two fixing plates 240. The two fixing plates 240 are respectively arranged on the two brackets 210. The first lifting driving member 110 and the top plate 120 are both arranged below the space between the two fixing plates 240.

Specifically, the two fixing plates 240 are respectively arranged above the two conveyor belts 220. It can be understood that when the circuit board moves to the oiling station, the first lifting driving member 110 drives the top plate 120 to rise. A plurality of positioning columns 140 are arranged on the top plate 120. The plurality of positioning columns 140 can rise together with the top plate 120, so that the plurality of positioning columns 140 pass through a plurality of through holes on the circuit board. As the top plate 120 continues to rise, the top plate 120 abuts against the circuit board through a plurality of support blocks 130. Under the action of the plurality of support blocks 130, the circuit board rises, so that the upper surface of the circuit board abuts against the two fixing plates 240. Under the action of the first lifting driving member 110, the top plate 120 and the two fixing plates 240 can clamp the circuit board, that is, the two fixing plates 240 and the plurality of support blocks 130 clamp the circuit board, so that the circuit board is fixed at the oiling station, ensuring that the circuit board does not shake during the oiling process, which is beneficial to improving the accuracy of oiling by the oiling head 310.
