Description

Technical Field

[0001] The utility model belongs to the field of PC boards, relates to spraying technology, and specifically is a surface hardening spraying device for PC boards. Background Technique

[0002] PC board is an engineering plastic board with excellent performance and wide application fields. In order to improve the surface hardness of the PC board, maintain optical properties, broaden application fields, improve processing performance, and extend service life, before use, a hardening coating will be covered on the surface of the PC board by using a spray gun or similar equipment to form a uniform and continuous hardening coating.

[0003] The existing surface hardening of PC boards mainly realizes the coating coverage through soaking, spraying, and roller coating. However, the above methods all have certain limitations. Soaking and roller coating are generally used for flat PC boards. For PC boards with bends, using this method will cause the coating to be thicker in some positions; spraying can be applied to various types of PC boards. Irregular PC boards will be erected on the corresponding hollow molds for spraying. However, after some PC boards are formed, there will be concave or right-angled parts. It is difficult to form a complete coating at this position directly by spraying, which will affect the subsequent use of the PC board. Therefore, the surface hardening of different types of PC boards all has a certain scope of use, and problems such as coating waste or uneven and incomplete coating are likely to occur during use.

[0004] Therefore, the utility model proposes a surface hardening spraying device for PC boards. Content of the Utility Model

This surface hardening spraying device for PC boards solves the problem that the existing methods of hardening coatings on the surface of PC boards used in the prior art all have certain limitations and are difficult to be applicable to products of various scales.

[0006] To achieve the above object, according to an embodiment of the first aspect of the utility model, a surface hardening spraying device for PC boards is proposed, including: a hardening seat, and a spraying mechanism is arranged inside the hardening seat. The spraying mechanism includes:

[0007] A number of support rods, the support rods are all slidably connected to the surface of the hardening seat, one end of the support rods far away from the hardening seat is in contact with the PC board, a support spring is fixedly connected between the support rods and the hardening seat, a number of the support rods are evenly divided into two groups, and the two groups of support rods are symmetrically arranged inside the hardening seat.

A transfer rod is rotatably connected inside both the driving block and the rolling block. A nozzle is fixedly connected to the surface of the transfer rod located inside the driving block, and a roller is detachably connected to the surface of the other transfer rod. Angle conversion components are arranged between the transfer rod and the telescopic tube far from the hardening seat.

[0010] Optionally, the fixing component includes a plurality of fixing blocks, all of which are slidably connected to the hardening seat. Adjacent two fixing blocks are symmetrically arranged. Fixing belts are fixedly connected to the surfaces of the fixing blocks. A plurality of fixing rings are rotatably connected inside the hardening seat.

[0028] As Figures 1-6 shown, the PC board surface hardening spraying device includes a hardening seat 1, and a spraying mechanism is arranged inside the hardening seat 1. The spraying mechanism includes:

[0029] A plurality of support rods 21, the support rods 21 are all slidably connected to the surface of the hardening seat 1, and one end of the support rods 21 far from the hardening seat 1 is attached to the PC board. The plurality of support rods 21 are evenly divided into two groups, and the two groups of support rods 21 are symmetrically arranged inside the hardening seat 1. A plurality of support rods 21 in a single group are arranged in a linear array on one side of the hardening seat 1. A support spring 22 is connected between the support rods 21 and the hardening seat 1 by a fixing block 31; A fixing component is arranged between the support rods 21 and the hardening seat 1;

[0030] It should be noted that the contact surfaces between the support rods 21 are rough, the gaps between the support rods 21 are small, and the width of a single support rod 21 is narrow;

[0031] Four telescopic tubes 23, the telescopic tubes 23 are all fixedly connected to the support rods 21. Two telescopic tubes 23 are fixed on the surface of the same group of support rods 21 and are arranged at intervals along the direction of the support rods 21;

[0032] A driving block 24 and a rolling block 25, the driving block 24 and the rolling block 25 are slidably connected to the support rods 21, the driving block 24 and the rolling block 25 are fixedly connected, and relative to the spraying direction of the PC board, the driving block 24 is fixed in front of the rolling block 25. A driving column 26 is fixedly connected to one side of the driving block 24 close to the telescopic tube 23, and the driving columns 26 are all slidably connected to the telescopic tubes 23 closer to the hardening seat 1;

[0033] It should be noted that the position of the rolling block 25 is not lower than the position of the driving block 24;

[0034] It should be noted that cylinders (not shown in the figure) or other driving structures (not shown in the figure) are arranged on two perpendicular surfaces of the driving block 24 and the rolling block 25, and the moving directions and heights of the driving block 24 and the rolling block 25 can be directly controlled respectively through data, or directly controlled by an existing robot arm (not shown in the figure) for PC board spraying to drive the driving block 24 and the rolling block 25 to change positions;

[0035] A transfer rod 27 is rotatably connected inside both the driving block 24 and the rolling block 25. A spray head 28 is fixedly connected to the surface of the transfer rod 27 located inside the driving block 24, and a roller 29 is detachably connected to the surface of the transfer rod 27 located inside the rolling block 25;

[0036] It should be noted that a relevant paint supply and pressurization structure (not shown in the figure) is provided inside the driving block 24;

[0037] A corner component is provided between the transfer rod 27 and the telescopic tube 23 at a position far from the hardening seat 1;

[0038] In the actual application process of this PC board surface hardening spraying device, the spray head 28 for spraying paint is arranged on the surface of the dense support rod 21. The movement trajectory of the spray head 28 can only be the same as that of the telescopic tube 23 through the telescopic tube 23 and the driving column 26 between them. After the support rod 21 and the PC board are attached, the support rod 21 will move under the pressure of the PC board. Therefore, during spraying, the shape of the support rod 21 is the shape of the PC board to be sprayed. At this time, it is possible to independently adjust whether the spray head 28 and the roller 29 need to rotate according to the shape gap between the two, and fix the spray head 28 and the roller 29. Then, after the spraying on the surface of the PC board is completed, the sprayed paint can be directly rolled evenly by the roller 29 to ensure the flatness of the hardened layer on the surface of the PC board;

[0039] In some specific implementation schemes, the above fixing component includes a plurality of fixing blocks 31. The surfaces of the fixing blocks 31 are all in contact with the surface of the support rod 21. The fixing blocks 31 are all slidably connected to the hardening seat 1. Adjacent two fixing blocks 31 are symmetrically arranged. Fixing belts 32 are fixedly connected to the surfaces of the fixing blocks 31. A plurality of fixing rings 33 are rotatably connected inside the hardening seat 1. Two fixing belts 32 are fixedly connected to a single fixing ring 33, and the fixed positions of the two fixing belts 32 on the surface of the fixing ring 33 are different and the winding directions are different;

[0040] In a further implementation scheme, a plurality of meandering shafts 34 are fixedly connected inside the fixing rings 33. The meandering shafts 34 are fixedly arranged in a circular array inside the fixing rings 33. A plurality of meandering rods 35 are threadedly connected to the hardening seat 1. The meandering rods 35 are adapted to the meandering shafts 34;

[0041] It should be noted that the meandering shafts 34 are arc-shaped inside the fixing rings 33;

[0042] In some specific implementation schemes, a connecting ring 41 is fixedly connected to the surface of the transfer rod 27. The connecting ring 41 is in contact with the roller 29. One end of the connecting ring 41 is rotatably connected to a connecting shaft 42, and a connecting rod 43 is slidably connected inside the connecting ring 41;

[0043] It should be noted that the connecting rod 43 is composed of cylinders of different diameters. A connecting groove (not shown in the figure) with a limited length is formed inside the connecting ring 41, that is, the movable distance of the connecting rod 43 inside the connecting ring 41 is limited.

[0044] A connecting ball 44 is fixedly connected to the surface of the connecting rod 43, and a spiral groove 45 is formed inside the connecting shaft 42. The connecting ball 44 is adapted to the spiral groove 45.

[0045] In some specific embodiments, the above-mentioned corner assembly includes a plurality of corner gears 51 slidably connected to the inside of the telescopic tube 23. The number of the corner gears 51 is the same as that of a single group of support rods 21. Driving gears 52 are fixedly connected to the surfaces of the intermediate rods 27. The driving gears 52 are engaged with the corner gears 51.

[0046] The working principle of the present invention: Place the PC board to be sprayed on the surface of the support rod 21. The support rod 21 is in contact with the surface of the PC board. Even if the plurality of support rods 21 are arranged in a shape, the telescopic tube 23 between the support rods 21 changes its shape, that is, the movement trajectory of the driving block 24 changes. After the shape formed by the plurality of support rods 21 is determined, rotate the winding rod 35 downward, drive the fixing belt 32 to wind through the winding shaft 34, and shorten the distance between the fixing blocks 31, so that the support rods 21 are in contact with each other. If there are surfaces in the PC board that are difficult to reach during vertical spraying, move the corner gears 51 inside the appropriate support rods 21 towards the driving block 24. After the adjustment is completed, start the relevant power to drive the driving block 24 and the rolling block 25 to move. When they move to a certain position, the corner gears 51 and the driving gears 52 come into contact, and the nozzle 28 and the roller 29 will rotate.

[0047] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
