Description

Technical Field

[0001] The utility model relates to the field of PCB production, in particular to a coating device for warped plates. Background Art

[0002] With the continuous development of PCB technology, various new PCBs such as mixed-pressure boards, yin-yang copper boards and other asymmetric boards have emerged. However, the special internal structure of these new PCBs often causes warping after lamination, so this type of PCB is also called a warped board. Warped board coating refers to coating ink on the surface of the warped board.

[0003] For example, a Chinese patent with the announcement number CN201862541U discloses a vertical automatic double-sided coating machine for PCB boards, wherein a left and right plate-joining lifting mechanism is arranged above the coating mechanism, and the left and right plate-joining lifting mechanisms include two lifting plate-joining mechanisms, and the sides of the lifting plate-joining mechanisms are provided with slide rails and lifting arms, and the rear end of the lifting arm is slidably connected to the slide rail, and a nut is arranged on the lifting arm, and a manipulator for grabbing the PCB board is arranged at the front end of the lifting arm. The manipulator of one lifting plate-joining mechanism is used to grab the upward movement of the PCB board, and the manipulator of the other lifting plate-joining mechanism is used to grab the two side edges of the PCB board. The above-mentioned coating machine has the following problems: the two side edges of the plate are the most serious positions of the plate warping, and if the manipulator grabs the two side edges of the warped plate, it is difficult to clamp the warped plate, thereby affecting the subsequent coating process. In view of this, the utility model proposes a coating device for warped plates to solve the above-mentioned problems. Utility Model Content

[0004] The utility model overcomes the shortcomings of the above-mentioned technology and provides a coating device for warped plate parts.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A coating device for warped plate members, comprising a coating clamp for clamping the top of the warped plate member, and a lifting mechanism for driving the coating clamp to move up and down; a positioning clamp for clamping the middle of the warped plate member is provided below the coating clamp; the positioning clamp comprises two positioning blocks symmetrically arranged in the front-to-back direction, and a first moving mechanism; the first moving mechanism is used to drive the two positioning blocks to move toward or away from each other; two coating wheels symmetrically arranged in the front-to-back direction are provided between the coating clamp and the positioning clamp; the two coating wheels move toward or away from each other via a second moving mechanism; the two coating wheels are used to clamp the warped plate member and apply oil to the warped plate member by rotating along their center axes.

[0007] Preferably, the coating clamping jaw and the positioning block are not on the same vertical line.

[0008] Preferably, the warped plate coating device comprises at least two positioning jaws on the same horizontal line, and the positioning jaws are symmetrically distributed about the central axis of the warped plate in the vertical direction.

[0009] Preferably, the coating device for the warped plate comprises at least two coating jaws on the same horizontal line, and the coating jaws are symmetrically distributed about the central axis in the vertical direction of the warped plate.

[0010] Preferably, the two coating wheels rotate in opposite directions along their central axes.

[0011] Preferably, the side of the positioning block that is in contact with the warped plate is provided with anti-slip grooves.

[0012] Preferably, the warped plate coating device further comprises a frame, and the first moving mechanism is mounted on the frame.

[0013] Preferably, the frame is provided with a third moving mechanism for driving the lifting mechanism to move in the front-rear direction.

[0014] Preferably, the warped plate coating device further comprises a rotating mechanism for driving the coating wheel to rotate, the second moving mechanism is mounted on the frame, and the second moving mechanism is used to simultaneously drive the rotating mechanism and the coating wheel to move in the forward and backward directions.

[0015] The coating process of the utility model for coating the warped plate is as follows: first, the coating jaws clamp the top of the warped plate, and then the lifting mechanism drives the coating jaws and the warped plate to descend, so that the warped plate descends to be opposite to the positioning block. Then, the two positioning blocks of the positioning jaws move toward each other, thereby clamping the warped plate. After the two positioning blocks clamp the warped plate, the coating jaws release the warped plate, and the lifting mechanism drives the coating jaws to rise to the original position, and the two coating wheels move toward each other to clamp the warped plate. After the two coating wheels clamp the warped plate, the two positioning blocks move away from each other to release the warped plate, and the coating wheel rotates along its central axis to apply oil to the warped plate. At the same time, the rotating coating wheel will push the warped plate upward. When the warped plate rises to the bottom of the coating jaws, the coating jaws clamp the warped plate again, and the coating of the warped plate is completed.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. Compared with the prior art in which the two side edges of the warped plate are clamped by edge-patrolling claws, the utility model uses two positioning blocks, one in front and one behind, to press the middle of the warped plate, avoiding the position where the plate is most severely warped, so that the positioning claws can firmly clamp the warped plate.

[0018] 2. The positioning jaws press the warped plate through two positioning blocks one in front and one behind. The positioning jaws can be applied to warped plates of any thickness, with high applicability. The positioning jaws have a simple structure, low cost, and are easy to use and maintain.

[0019] 3. The utility model includes at least two coating clamps on the same horizontal line and at least two positioning clamps on the same horizontal line. The positioning clamps and the coating clamps are symmetrically distributed on the left and right sides with respect to the central axis in the vertical direction of the warped plate, and can evenly clamp the warped plate and further firmly clamp the warped plate.

[0029] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0030] Reference Figure 1-5 , an embodiment of a warped plate coating device of the utility model is proposed:

[0031] A coating device for warped plate 1 includes a coating clamp 2 for clamping the top of the warped plate 1 and a lifting mechanism (not shown in the drawings) for driving the coating clamp 2 to move up and down. A positioning clamp 3 for clamping the middle of the warped plate 1 is provided below the coating clamp 2. The positioning clamp 3 includes two positioning blocks 31 symmetrically arranged in the front-to-back direction and a first moving mechanism 32 for driving the two positioning blocks 31 to move toward or away from each other. Two coating wheels 4 symmetrically arranged in the front-to-back direction are provided between the coating clamp 2 and the positioning clamp 3. The coating device for warped plate 1 also includes a rotating mechanism (not shown in the drawings) and a second moving mechanism (not shown in the drawings) for driving the rotating mechanism to move in the front-to-back direction. The rotating mechanism is used to drive the coating wheel 4 to rotate about its central axis, and the two coating wheels 4 rotate in opposite directions along their central axes. The two coating wheels 4 move toward or away from each other through the second moving mechanism.

[0032] The process of coating the warped plate 1 of the utility model is as follows: Figure 3 As shown, first, the coating clamp 2 clamps the top of the warped plate 1, and then the lifting mechanism drives the coating clamp 2 and the warped plate 1 to descend, so that the warped plate 1 descends to face the positioning block 31. Figure 4 As shown, the two positioning blocks 31 of the positioning clamp 3 then move toward each other, thereby clamping the warped plate 1. After the two positioning blocks 31 clamp the warped plate 1, the coating clamp 2 releases the warped plate 1, and the lifting mechanism drives the coating clamp 2 to rise to the original position, and the two coating wheels 4 move toward each other to clamp the warped plate 1. Figure 5 As shown, after the two coating wheels 4 clamp the warped plate 1, the two positioning blocks 31 move apart to loosen the warped plate 1, and the coating wheel 4 rotates along its central axis to apply oil to the warped plate 1. At the same time, the rotating coating wheel 4 pushes the warped plate 1 upward. When the warped plate 1 rises to under the coating jaws 2, the coating jaws 2 clamp the warped plate 1 again, and the coating of the warped plate 1 is completed.

[0033] During coating of the warped plate 1, while the coating wheel 4 acts on the warped plate 1, the lifting mechanism drives the coating jaw 2 to reset, and the motion trajectories of the coating jaw 2, the positioning jaw 3, and the coating wheel 4 do not overlap, and the moving line design is reasonable.

[0034] like Figure 6-8As shown, in the prior art, the two side edges of the warped plate 1 are clamped by the edge patrol claws 5. Since the two side edges of the plate are the most severely warped positions of the plate, when the edge patrol claws 5 clamp the warped plate 1, there is a large gap between the edge patrol claws 5 and the warped plate 1, which makes it difficult for the edge patrol claws 5 to clamp the warped plate 1. However, the utility model uses two positioning blocks 31 to press the middle of the warped plate 1 one in front and one behind, avoiding the most severely warped position of the plate. The warping of the middle of the warped plate 1 is not as serious as that of the two side edges. The positioning blocks 31 can better fit the surface of the warped plate 1, so that the positioning claws 3 can firmly clamp the warped plate 1.

[0035] Moreover, the positioning clamp 3 presses the warped plate 1 one after another through two positioning blocks 31, and the positioning clamp 3 can be applied to warped plates 1 of any thickness, and has high applicability. The positioning clamp 3 has a simple structure, low cost, and is easy to use and maintain.

[0036] Specifically, the coating clamp 2 and the positioning block 31 are not on the same vertical line. When the two positioning blocks 31 press the warped plate 1 one after the other, the positioning blocks 31 and the coating clamp 2 will not affect the positioning blocks 31 clamping the warped plate 1.

[0037] The warped plate coating device includes at least two coating clamps 2 on the same horizontal line and at least two positioning clamps 3 on the same horizontal line, and the positioning clamps 3 and the coating clamps 2 are symmetrically distributed left and right about the central axis of the warped plate 1 in the vertical direction, so as to evenly clamp the warped plate 1 and further firmly clamp the warped plate 1.

[0038] In this embodiment, the coating device of the warped plate 1 is provided with two coating jaws 2 and two positioning jaws 3, but in other embodiments, the number of coating jaws 2 and positioning jaws 3 is not limited. The larger the area of ​​the warped plate 1 is, the more the number of coating jaws 2 and positioning jaws 3 can be set.

[0039] like Figure 5 As shown, the side of the positioning block 31 that contacts the warped plate 1 is provided with anti-slip grooves 33 .

[0040] Specifically, the coating device for the warped plate 1 further includes a frame (not shown in the drawings), and the first moving mechanism 32 and the second moving mechanism are mounted on the frame. The frame is also provided with a third moving mechanism for driving the lifting mechanism to move forward and backward, and the lifting mechanism moves forward and backward to obtain the uncoated warped plate 1 or to transport the coated warped plate 1 to other stations.

[0041] Specifically, the lifting mechanism, the first moving mechanism 32, the second moving machine, and the third moving mechanism may be a screw transmission mechanism driven by a motor. The first moving mechanism 32, the second moving machine, and the third moving machine may also be a lifting cylinder, which is not limited in this embodiment.

[0042] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
