Description

Technical Field

[0001] This utility model relates to the field of conformal coating technology for new energy PCBA boards, specifically a new energy product conformal coating automatic spraying and flipping bracket. Background Technology

[0002] In the field of new energy, PCB (printed circuit board) is an important carrier of electronic components. After assembly, it usually needs to be coated with conformal coating to enhance its moisture resistance, salt spray resistance, mildew resistance and other properties, and improve the durability and reliability of the whole board in complex environments.

[0003] Currently, the main methods for applying conformal coating to new energy PCBs are placing the PCB directly on a machine track for positioning and spraying, or using a universal bracket for fixation. These methods have several drawbacks. For example, because the PCB itself is thin and has poor load-bearing capacity, it is prone to bending and deformation under its own weight without effective support, leading to uneven spraying and affecting the protective effect of the conformal coating. Simultaneously, the nozzle positioning is prone to deviation, resulting in spraying area offset or repeated spraying, and in severe cases, even damage to the PCB. Furthermore, universal brackets often cannot precisely match different product models, requiring frequent manual adjustments of the track width and spraying position during operation, increasing debugging difficulty and reducing production efficiency. Therefore, there is an urgent need for an automatic conformal coating flipping bracket for new energy products to solve these technical defects. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic spraying and flipping bracket for conformal coating of new energy products, so as to solve the problem of PCB board deformation mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic spraying and flipping bracket for conformal coating of new energy products, comprising a positioning mother frame and self-locking buckles. The positioning mother frame is equipped with a product sub-frame. Multiple sets of self-locking buckles are arranged at both ends of the positioning mother frame. Each self-locking buckle includes a base fixed to the surface of the positioning mother frame. An operating handle is hinged to the top of the base. A connecting rod is hinged to one side of the operating handle. The connecting rod is also hinged to the base. A screw is threadedly connected inside the connecting rod. A locking nut is installed between the top of the screw and the connecting rod. A pressure block is fixedly connected to the bottom of the screw.

[0006] As a further technical solution of this utility model, four sets of self-locking buckles are provided on one side of the positioning mother frame, and three sets are provided on the other side of the positioning mother frame.

[0007] As a further technical solution of this utility model, the base is provided with a mounting hole for connection with the positioning mother frame, and screws are driven into the mounting hole to assemble the base with the positioning mother frame.

[0008] As a further technical solution of this utility model, the product sub-frame has steps protruding from its surface at both ends, and anti-foolproof grooves are processed at one set of steps. An anti-foolproof plate is fixedly connected to the top rear end of the positioning mother frame, and the anti-foolproof plate and the anti-foolproof groove are fitted and matched.

[0009] As a further technical solution of this utility model, an indicator arrow is provided inside the product sub-frame, which is used to indicate the installation direction of the product sub-frame inside the positioning mother frame.

[0010] As a further technical solution of this utility model, the two ends of the positioning mother frame are fixed with flip positioning holes, and each set of flip positioning holes has three equally spaced through holes.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the automatic coating and flipping bracket for three-proof paint of new energy products not only realizes that the width of the equipment track can be fixed to reduce the difficulty of operation and adjustment, effectively prevent PCB board deformation, realize batch processing of PCB boards of the same batch, and is simple and fast to operate, but also realizes that the forward and reverse painting operations do not need to be flipped and adjusted.

[0012] (1) By setting up a self-locking buckle, operating handle, base, connecting rod, locking nut, screw and pressure block, the product sub-frame is assembled in the positioning mother frame, which can fix the width of the equipment track and reduce the difficulty of the operator's debugging. The operator only needs to align the product sub-frame with the positioning mother frame and put it in. After the PCB board is placed on the product sub-frame, the self-locking buckle is operated to press the PCB board tightly. By using the prefabricated special positioning mother frame and different product sub-frames together, the deformation of the PCB board can be effectively prevented, ensuring the consistency of spraying and the quality of the product.

[0013] (2) By setting up product sub-frames, steps, indicator arrows, and anti-fooling grooves, the entire product sub-frame is placed in the positioning mother frame. The placement direction is determined by the pressure block, and a screw is set to indicate the placement direction of the PCB board. The steps are used to position the product sub-frames. During operation, the same batch of PCB boards can be processed in batches. The operation is simple and fast, and the learning curve is low.

[0014] (3) By setting up flip positioning holes, flip positioning holes are left on both sides of the positioning mother frame for use by external 180-degree flipping machines. Forward and reverse painting operations do not require flipping and adjusting, which can achieve better paint coverage effect, avoid the problem of incomplete paint coverage due to improper operation, and improve painting efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides an embodiment of an automatic spraying and flipping bracket for three-proof paint of new energy products, including a positioning mother frame 1 and self-locking buckles 2. The positioning mother frame 1 is equipped with a product sub-frame 5. Multiple sets of self-locking buckles 2 are arranged at both ends of the positioning mother frame 1. The self-locking buckles 2 include a base 202 fixed to the surface of the positioning mother frame 1. An operating handle 201 is hinged to the top of the base 202. A connecting rod 203 is hinged to one side of the operating handle 201. The connecting rod 203 is also hinged to the base 202. A screw 205 is threadedly connected inside the connecting rod 203. A locking nut 204 is installed between the top of the screw 205 and the connecting rod 203. A pressure block 206 is fixedly connected to the bottom of the screw 205. Four sets of self-locking buckles 2 are arranged on one side of the positioning mother frame 1 and three sets are arranged on the other side of the positioning mother frame 1. The base 202 is reserved with a mounting hole for connection with the positioning mother frame 1. Screws are driven into the mounting hole to assemble the base 202 with the positioning mother frame 1.

[0022] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, after the PCB board is placed on the product sub-frame 5, the operating handle 201 is manually turned. Under the linkage of the operating handle 201, the connecting rod 203 is lifted. After releasing the handle, the operating handle 201 returns to its original position, and the connecting rod 203 falls back down. The pressure block 206 can then press the PCB board firmly. The pressing force of the pressure block 206 is adjusted by the screw 205. Loosening the locking nut 204 allows the bottom height of the screw 205 to be adjusted, thereby adjusting the pressing force of the pressure block 206 to avoid unstable positioning due to excessive pressure or deformation of the PCB board due to excessive pressure.

[0023] The product sub-frame 5 has steps 501 protruding from its surface at both ends. One set of steps 501 has anti-misbehavior grooves 503. Anti-misbehavior plate 3 is fixedly connected to the top rear end of the positioning mother frame 1. Anti-misbehavior plate 3 fits and matches with anti-misbehavior groove 503. An indicator arrow 502 is provided inside the product sub-frame 5. The indicator arrow 502 is used to indicate the installation direction of the product sub-frame 5 inside the positioning mother frame 1.

[0024] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the entire product sub-frame 5 is placed inside the positioning mother frame 1. The placement direction is determined by the pressure block 206, and a screw 205 is provided to indicate the placement direction of the PCB board. The step 501 is used to position the product sub-frame 5. During operation, it is only necessary to replace the product sub-frame 5 with one that is compatible with the size of the PCB board to process the same batch of PCB boards in batches.

[0025] The positioning mother frame 1 has flip positioning holes 4 fixed at both ends, and each set of flip positioning holes 4 has three equally spaced through holes.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the positioning mother frame 1 has flip positioning holes 4 at both ends for use by an external 180-degree flipping machine. The forward and reverse painting operations do not require flipping and adjusting, which can achieve a better paint coverage effect.

[0027] Working principle: The entire product sub-frame 5 is placed inside the positioning mother frame 1. The placement direction is determined by the pressure block 206, and a screw 205 indicates the placement direction of the PCB board. The step 501 is used to position the product sub-frame 5. During operation, the operating handle 201 is manually turned. Under the linkage of the operating handle 201, the connecting rod 203 is lifted. After releasing the handle, the operating handle 201 returns to its original position, and the connecting rod 203 falls back down. The pressure block 206 can then press the PCB board firmly. The pressing force of the pressure block 206 is adjusted by the screw 205. The height of the bottom of the adjusting screw 205 can be adjusted by loosening the locking nut 204, thereby adjusting the clamping force of the pressure block 206 to avoid unstable positioning due to excessive pressure or deformation of the PCB board due to excessive pressure. The operator only needs to align the product sub-frame 5 with the positioning mother frame 1 and place it in. After the PCB board is placed on the product sub-frame 5, the self-locking buckle 2 is used to press the PCB board tightly. The positioning mother frame 1 has flip positioning holes 4 on both sides for use by the external 180-degree flipping machine. There is no need to flip and adjust the position for forward and reverse painting operations.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
