Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and particularly relates to a lock cover device. Background Art

[0002] The circuit board is the core component of electronic products. Quality problems of the circuit board may lead to a decline in the performance of the entire electronic product or even a malfunction. In order to enclose the internal space of the circuit board to prevent dust, foreign objects, etc. from entering the inside of the circuit board, screws are usually used to install a cover on the circuit board to ensure that the circuit board can operate normally for a long time. On the other hand, the cover can also provide protection for the circuit board to ensure that the circuit board is not directly affected by external impact forces.

[0003] In the prior art, threaded holes with different apertures are provided on the circuit board, and through holes with different apertures are provided on the cover. First, the operator aligns and places the cover on the circuit board so that the through holes with different apertures on the cover respectively align with the corresponding threaded holes. Then the operator puts screws of different specifications into the through holes with corresponding apertures on the cover, and finally uses electric bits of different models to tighten the screws of different specifications respectively to complete the locking installation of the cover. This method that requires the operator to constantly change the electric bit to lock the cover is relatively slow and is not conducive to improving the locking efficiency of the cover of the circuit board.

[0047] It can be understood that when the cover needs to be locked onto the circuit board, the operator can first place the circuit board on the slide plate 110, and then activate the clamping and positioning device 200. The clamping and positioning device 200 can clamp the circuit board and the cover, so that the first through hole, the second through hole and the third through hole on the cover can respectively align with the first threaded hole, the second threaded hole and the third threaded hole on the circuit board. After the circuit board and the cover are fixed, the slide plate 110 moves forward to the first station, and drives the clamping and positioning device 200, the circuit board and the cover to move to the first station together. After the circuit board and the cover move to the first station, the first screw tightening device 300 puts the first screw into the first through hole on the cover and the first threaded hole on the circuit board, and then the first screw tightening device 300 tightens the first screw, so that the first screw is threadedly connected with the inner wall of the first threaded hole on the circuit board, and the first screw is tightened. After the first screw is tightened, the slide plate 110 continues to move forward to the second station, and drives the clamping and positioning device 200, the circuit board and the cover to move to the second station together. Then the second screw tightening device 400 puts the second screw into the second through hole on the cover and the second threaded hole on the circuit board, and then the second screw tightening device 400 tightens the second screw, so that the second screw is threadedly connected with the inner wall of the second threaded hole on the circuit board, and the second screw is tightened.

[0048] After the second screw is tightened, the slide plate 110 continues to move forward to the third station, and drives the clamping and positioning device 200, the circuit board and the cover to move to the third station together. Then the third screw tightening device 500 puts the third screw into the third through hole on the cover and the third threaded hole on the circuit board, and then the third screw tightening device 500 tightens the third screw, so that the third screw is threadedly connected with the inner wall of the third threaded hole on the circuit board, and the third screw is tightened. Finally, the cover is locked onto the circuit board by the first screw, the second screw and the third screw to complete the installation of locking the cover of the circuit board. After the cover is locked, the clamping and positioning device 200 releases the circuit board and the cover, and the operator removes the circuit board from the slide plate 110. This cover locking device can tighten the first screw, the second screw and the third screw in sequence, so that the cover can be quickly locked and installed on the circuit board, which is beneficial to improving the efficiency of locking the cover of the circuit board.

[0049] This cover locking device can avoid the operator from changing different types of electric bit heads back and forth, which is beneficial to improving the efficiency of locking the cover of the circuit board.

[0050] It should be noted that for the convenience of explanation, after the clamping and positioning device 200 clamps the potentiometer board and the cover, the front side of the potentiometer board and the cover facing forward is defined as the front side, the top side of the potentiometer board and the cover facing upward is defined as the top side, and the rear side of the potentiometer board and the cover facing backward is defined as the rear side. Figure 2The shaded part in [the figure] is the cover. In the present utility model, a plurality of first threaded holes, a plurality of second threaded holes, and a plurality of third threaded holes are provided on the front side, rear side, and top surface of the potential plate, and a plurality of first through holes, a plurality of second through holes, and a plurality of third through holes are provided on the front side, rear side, and top surface of the cover. After the clamping and positioning device 200 clamps the circuit board and the cover, the plurality of first threaded holes on the front side of the potential plate respectively correspond to the plurality of first through holes on the front side of the cover one by one; the plurality of second threaded holes on the rear side of the potential plate respectively correspond to the plurality of second through holes on the rear side of the cover one by one; the plurality of third threaded holes on the top surface of the potential plate respectively correspond to the plurality of third through holes on the top surface of the cover one by one.

[0051] Reference Figures 4 to 6 , the cover locking device further includes a support 120 and a rotation driving member 270. The support 120 is rotatably provided on the slide plate 110. The clamping and positioning device 200 is provided on the support 120. The rotation driving member 270 is provided on the slide plate 110. The rotation driving member 270 is used to drive the support 120 to rotate so that the top surface or side surface of the circuit board and the cover clamped by the clamping and positioning device 200 can face upward. It can be understood that the side surfaces of the circuit board and the cover are the front side and the rear side. When the slide plate 110 moves to the first working position, the slide plate 110, the clamping and positioning device 200, the circuit board, and the cover move to the first working position together. At this time, the support 120 is in the initial state, the top surfaces of the circuit board and the cover face upward, the first screw tightening device 300 puts the first screw into the first through hole on the top surface of the cover and the first threaded hole on the top surface of the circuit board, and then the first screw tightening device 300 tightens the first screw at the top surface of the circuit board and the cover. After the first screw at the top surface of the circuit board and the cover is tightened, the rotation driving member 270 drives the support 120 to rotate, so that the rear side surface of the circuit board and the cover clamped by the clamping and positioning device 200 faces upward. The first screw tightening device 300 puts the first screw into the first through hole on the rear side surface of the cover and the first threaded hole on the rear side surface of the circuit board, and then the first screw tightening device 300 tightens the first screw at the rear side surface of the circuit board and the cover. After the first screw at the rear side surface of the circuit board and the cover is tightened, the rotation driving member 270 drives the support 120 to rotate, so that the front side surface of the circuit board and the cover clamped by the clamping and positioning device 200 faces upward. The first screw tightening device 300 puts the first screw into the first through hole on the front side surface of the cover and the first threaded hole on the front side surface of the circuit board, and then the first screw tightening device 300 tightens the first screw at the front side surface of the circuit board and the cover. At this time, the cover is locked and installed on the circuit board by the first screw. Then the rotation driving member 270 drives the support 120 to rotate, so that the top surface of the circuit board and the cover clamped by the clamping and positioning device 200 faces upward again.

[0052] The skateboard 110 moves forward to the second working station and the third working station in sequence. Similar to the above process, the rotary driving member 270 can drive the support 120 to rotate, so that the rear side, front side and top surface of the circuit board and the cover clamped by the clamping and positioning device 200 face upward in sequence. Furthermore, the second screw tightening device 400 can screw the second screws on the top surface, front side and rear side of the circuit board and the cover, and the third screw tightening device 500 can screw the third screws on the top surface, front side and rear side of the circuit board and the cover to complete the locking installation of the cover of the circuit board.

[0053] Reference Figures 4 to 6 , the clamping and positioning device 200 includes a first baffle 210, a first push plate 220 and a first linear driving member 250. The first baffle 210 and the first linear driving member 250 are both arranged on the support 120. The output end of the first linear driving member 250 is connected to the first push plate 220. The area between the first push plate 220 and the first baffle 210 is used to accommodate the circuit board and the cover. The first linear driving member 250 is used to drive the first push plate 220 to approach the first baffle 210, so that the first push plate 220 and the first baffle 210 can clamp the circuit board and the cover. The clamping and positioning device 200 includes a second baffle 230, a second push plate 240 and a second linear driving member 260. The second baffle 230 and the second linear driving member 260 are both arranged on the support 120. The output end of the second linear driving member 260 is connected to the second push plate 240. The area formed by enclosing the second push plate 240, the second baffle 230, the first push plate 220 and the first baffle 210 is used to accommodate the circuit board and the cover. The second linear driving member 260 is used to drive the second push plate 240 to approach the second baffle 230, so that the second push plate 240 and the second baffle 230 can clamp the circuit board and the cover.

[0054] It can be understood that when the locking installation of the cover needs to be carried out, the operator can put the circuit board and the cover together into the area formed by enclosing the second push plate 240, the second baffle 230, the first push plate 220 and the first baffle 210. Then the first linear driving member 250 and the second linear driving member 260 are started. The first linear driving member 250 drives the first push plate 220 to move towards the first baffle 210, so that the first push plate 220 and the first baffle 210 clamp the circuit board and the cover. The second linear driving member 260 drives the second push plate 240 to move towards the second baffle 230, so that the second push plate 240 and the second baffle 230 clamp the circuit board and the cover. Furthermore, the circuit board and the cover are completely clamped and fixed on the support 120. Specifically, the first baffle 210 and the first push plate 220 are respectively arranged on the front and rear sides of the support 120, and the second baffle 230 and the second push plate 240 are respectively arranged on the left and right sides of the support 120.

Both the first avoidance hole 211 and the second avoidance hole 221 are used for the tightening ends of the first screw tightening device 300, the second screw tightening device 400, and the third screw tightening device 500 to pass through. Before placing the circuit board and the cover on the support 120, the operator will first perform a preliminary installation of the circuit board and the cover, so that the circuit board is placed and aligned with the cover, and then they are placed together into the area surrounded by the second push plate 240, the second baffle 230, the first push plate 220, and the first baffle 210.

[0056] Reference Figure 3 and Figure 4 , the cover locking device further includes a conveying device 130. The conveying device 130 is arranged on the machine table 100 and is used to convey the circuit board from the back to the front. Specifically, in the embodiment of the present utility model, the rear end of the conveying device 130 corresponds to the loading manipulator, and the front end of the conveying device 130 is correspondingly arranged with the unloading manipulator. After the circuit board is processed in the upstream device, the circuit board can be placed on the conveying device 130 by the loading manipulator. Then the operator can place the circuit board and the cover on the conveying device 130 together into the area surrounded by the second push plate 240, the second baffle 230, the first push plate 220, and the first baffle 210 to complete the locking and installation of the cover of the circuit board. After the locking and installation of the cover of the circuit board is completed, the first push plate 220 and the second push plate 240 release the circuit board and the cover, and then the operator can remove the circuit board with the locked cover from the support 120 and place it on the conveying device 130, so that the conveying device 130 can convey the circuit board to the unloading manipulator, and the unloading manipulator can carry the circuit board to the downstream processing device.

[0057] Specifically, the conveying device 130 includes two brackets 131 and two conveyor belts 132. Both the two brackets 131 and the two conveyor belts 132 are parallel to the front-rear direction. The two conveyor belts 132 are respectively rotatably connected to the brackets 131, and the two conveyor belts 132 are respectively used to support the circuit board so that the circuit board can move along the front-rear direction. The two conveyor belts 132 are respectively abutted against the left and right sides of the circuit board, and the two conveyor belts 132 rotate, so that the two conveyor belts 132 drive the circuit board to move forward. The conveying device 130 further includes two support plates, which are respectively arranged on the two brackets 131, and are respectively arranged in the area surrounded by the two conveyor belts 132, and the two support plates respectively support the circuit board through the two conveyor belts 132.

[0058] Reference Figure 7, the first screw tightening device 300 includes a first screw feeding assembly 310, a first moving assembly 320, and a first adsorption bit assembly 330. The first screw feeding assembly 310 is used to supply first screws. The output end of the first moving assembly 320 is connected to the first adsorption bit assembly 330. The first adsorption bit assembly 330 is disposed above the clamping and positioning device 200. The first moving assembly 320 is used to drive the first adsorption bit assembly 330 to move in the up and down direction, left and right direction, and front and back direction, so that the first adsorption bit assembly 330 can adsorb the first screws at the first screw feeding assembly 310 and thread the first screws with the inner wall of the first threaded holes.

[0059] It can be understood that the first moving assembly 320 can drive the first adsorption bit assembly 330 to move in the up and down direction, left and right direction, and front and back direction, so that the first adsorption bit assembly 330 can move to the position of the first screw feeding assembly 310, and the first adsorption bit assembly 330 adsorbs the first screws on the first screw feeding assembly 310. Then the first moving assembly 320 drives the first adsorption bit assembly 330 to move above the clamping and positioning device 200, so that the first screws adsorbed by the first adsorption bit assembly 330 can be aligned with the first through holes on the cover. Then the first moving assembly 320 drives the first adsorption bit assembly 330 to descend, and the first adsorption bit assembly 330 drives the first screws to rotate, so that the first screws pass through the first through holes on the cover and the first threaded holes on the circuit board, and thread the first screws with the inner wall of the first threaded holes to complete the tightening of the first screws. The first adsorption bit assembly 330 includes a first electric bit and a first suction nozzle. The first suction nozzle uses the adsorption force generated by compressed air to pick up a single first screw, and then runs to the circuit board and the cover. The first electric bit descends and rotates the first screw to complete the tightening of the first screw.

[0060] In the present invention, the structures and working principles of the second screw tightening device 400 and the third screw tightening device 500 are completely the same as those of the first screw tightening device 300. The difference is that the second screw tightening device 400 supplies second screws and tightens second screws, and the third screw tightening device 500 supplies third screws and tightens third screws.

[0061] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0062] Certainly, the present utility model is not limited to the above-mentioned embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present utility model, and these equivalent deformations or substitutions are all included within the scope defined by the claims of this application.
