Description

Technical Field

[0001] The utility model relates to the technical field of PCBA coating, in particular to a PCBA coating jig with a dust cleaning function. Background Art

[0002] PCBA coating jigs are specialized tools used to apply conformal coatings (moisture-proof, dust-proof, and anti-corrosion) during the PCBA (Printed Circuit Board Assembly) process. The design of these jigs must consider the PCBA's size, shape, component distribution, and coating process requirements. In the electronics manufacturing process, PCBA coating jigs are essential tools for securing and protecting circuit boards. These jigs are particularly critical when applying protective layers like conformal coatings (moisture-proof, dust-proof, and anti-corrosion), as they ensure even distribution of the coating and protect the circuit boards from contamination.

[0003] For example, a PCBA coating jig disclosed in Chinese patent CN220371350U can effectively fix and shield the product PCBA board during actual use, avoiding the adverse phenomena of glue splashing and overflowing when the product is coated, shortening the working cycle, improving production efficiency, and bringing great convenience to production. This PCBA coating jig can also quickly remove the carrier to which it is transferred after coating the product, effectively ensuring the collection efficiency after the coating process.

[0004] Although this structure can mask areas that do not require coating, after coating one side, the PCBA needs to be removed, flipped over, and clamped again, which is inconvenient. Therefore, we propose a PCBA coating jig with a dust cleaning function that can quickly flip the clamped PCBA to improve coating efficiency. Utility Model Content

[0005] The purpose of the present invention is to provide a PCBA coating jig with a dust cleaning function to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a PCBA coating jig with a dust cleaning function, comprising a processing table, a clamping mechanism provided inside the processing table, a lifting mechanism fixedly installed on the top surface of the processing table, a moving mechanism fixedly installed on one end of the lifting mechanism away from the processing table, a coating mechanism provided inside the moving mechanism, and a processing assembly provided outside the clamping mechanism, the processing assembly including a flipping assembly provided outside the clamping mechanism, and a soot blowing assembly provided outside the flipping assembly.

[0007] Preferably, the flipping assembly includes a rotating column rotatably connected to the inner side of the processing table, a sleeve is fixedly installed on the outer wall of the rotating column, a spring is provided inside the sleeve, a limit plate is fixedly installed on the end of the spring, a clamping block is provided on the side of the limit plate away from the spring, a first limit block is fixedly installed on the inner side of the processing table, a second limit block is fixedly installed above the first limit block, a connecting rod is fixedly installed on the inner side of the moving mechanism, and a hook is fixedly installed on the bottom of the connecting rod.

[0008] Preferably, the sootblowing assembly includes a fixed block fixedly mounted on the outer wall of the connecting rod, a sliding rod fixedly mounted on the bottom of the fixed block, a sealing ring fixedly mounted on the end of the sliding rod away from the fixed block, an air pipe is sleeved on the outer wall of the sealing ring, an air pipe is connected to the end of the air pipe and an air blowing frame is provided, and a support block is fixedly mounted on the outer wall of the air pipe.

[0009] Preferably, the hook is arranged at an inclined surface away from one end of the connecting rod, and the outer wall of the block is arranged at an inclined surface. Under the restriction of the inclined surface, the hook moving upward can drive the block to deflect with the center of the rotating cylinder as the rotation center.

[0010] Preferably, there are eight card blocks, which are distributed around the center of the rotating cylinder. Under the card block restriction, the flipped card blocks can be restricted.

[0011] Preferably, the sealing ring is made of rubber, and the outer wall of the sealing ring is slidably arranged with the inner wall of the trachea. Under the restriction of the sealing ring, the gas inside the trachea can be pushed to clean the dust on the surface of the PCBA board.

[0012] Preferably, the support block is fixedly mounted on the top surface of the processing table. There are two support blocks, which are symmetrically distributed about the center line of the top surface of the processing table. With the support of the support blocks, the slide rod and the air pipe can slide stably.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The PCBA coating jig with dust cleaning function is composed of a flip assembly. When the PCBA board needs to be coated, it is first clamped by the clamping mechanism. At this time, the lifting mechanism is started to drive the moving mechanism and the coating mechanism to move downward to coat the PCBA board. The moving mechanism can drive the coating mechanism to move flexibly and accurately avoid the parts that do not need to be coated. When the coating is completed, the clamped PCBA board needs to be flipped, and the lifting mechanism is started to drive the moving mechanism to move upward. The moving mechanism drives the connecting rod and the hook upward. The hook moves away from its inclined surface and contacts with the side of the card block away from its inclined surface. The hook pulls the card block, causing the card block to drive the sleeve to rotate, and the sleeve drives the rotating column to rotate accordingly. The inclined surface of the other card block contacts and squeezes the inclined surface of the first limit block, driving the clamping mechanism to deflect. The lifting mechanism is then started to drive the hook downward, causing the inclined surface of the hook to squeeze the inclined surface of the card block, causing the card block to slide toward the inside of the sleeve and squeeze the spring. At this time, the side of the other card block away from its inclined surface contacts the side of the second limit block away from its inclined surface to prevent the rotating column from rotating, thereby flipping the clamped PCBA board.

[0015] 2. The PCBA coating jig with dust cleaning function is composed of a soot blowing assembly as one component. When the PCBA board is coated, the dust on its surface needs to be cleaned. At this time, when the lifting mechanism drives the moving mechanism to move downward, the connecting rod fixed on the outer wall of the moving mechanism drives the fixed block downward, and the fixed block drives the sliding rod to move downward. The sliding rod drives the sealing ring to slide inside the air pipe. Since the sealing ring and the air pipe are sealed and sliding, under its restriction, the sealing ring pushes the gas inside the air pipe, and blows through the blowing frame to clean the dust on the surface of the clamped PCBA board.

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described with reference to the accompanying drawings.

[0024] Example 1, a preferred embodiment of a PCBA coating jig with dust cleaning function provided by the present invention is as follows: Figures 1 to 6 Shown: A PCBA coating jig with a dust cleaning function, comprising a processing table 1;

[0025] A clamping mechanism 2 is provided inside the processing table 1;

[0026] A lifting mechanism 3 is fixedly installed on the top surface of the processing table 1;

[0027] A moving mechanism 4 is fixedly installed on one end of the lifting mechanism 3 away from the processing table 1;

[0028] A coating mechanism 5 is provided inside the moving mechanism 4;

[0029] And a processing component 6 is arranged outside the clamping mechanism 2, the processing component 6 includes a flipping component 61 arranged outside the clamping mechanism 2, the flipping component 61 includes a rotating column 611 rotatably connected to the inner side of the processing table 1, a sleeve 612 is fixedly installed on the outer wall of the rotating column 611, a spring 613 is arranged inside the sleeve 612, a limit plate 614 is fixedly installed on the end of the spring 613, a clamping block 615 is provided on the side of the limit plate 614 away from the spring 613, a first limit block 616 is fixedly installed on the inner side of the processing table 1, a second limit block 617 is fixedly installed above the first limit block 616, a connecting rod 618 is fixedly installed on the inner side of the moving mechanism 4, and a hook 619 is fixedly installed on the bottom of the connecting rod 618.

[0030] In this embodiment, when the PCBA board needs to be coated, it is first clamped by the clamping mechanism 2. At this time, the lifting mechanism 3 is started to drive the moving mechanism 4 and the coating mechanism 5 to move downward to coat the PCBA board. The moving mechanism 4 can drive the coating mechanism 5 to move flexibly and accurately avoid the parts that do not need to be coated. When the coating is completed, the clamped PCBA board needs to be flipped over, and the lifting mechanism 3 is started to drive the moving mechanism 4 to move upward. The moving mechanism 4 drives the connecting rod 618 and the hook 619 to move upward. The hook 619 is away from its inclined side and contacts the block 615 away from its inclined side. The hook 61 Pull the block 615, causing it to rotate the sleeve 612, which in turn causes the rotating column 611 to rotate accordingly. The inclined surface of the other block 615 contacts and squeezes the inclined surface of the first limit block 616, causing the clamping mechanism 2 to deflect. Then, the lifting mechanism 3 is activated to drive the hook 619 downward, causing the inclined surface of the hook 619 to press against the inclined surface of the block 615, causing the block 615 to slide into the sleeve 612 and press the spring 613. At this time, the side of the other block 615 away from its inclined surface contacts the side of the second limit block 617 away from its inclined surface, preventing the rotating column 611 from rotating, thereby flipping the clamped PCBA board.

[0031] Furthermore, the hook 619 is arranged at an inclined surface at one end away from the connecting rod 618, and the outer wall of the block 615 is arranged at an inclined surface. Under its restriction, the upward moving hook 619 can drive the block 615 to deflect with the center of the rotating column 611 as the rotation center.

[0032] Furthermore, there are eight clamping blocks 615 , which are distributed around the center of the rotating column 611 . Under the restriction of the clamping blocks 615 , the flipped clamping blocks 615 can be restricted.

[0033] Example 2, based on Example 1, the preferred embodiment of the PCBA coating jig with dust cleaning function provided by the present invention is as follows: Figures 1 to 6 As shown: the sootblowing assembly 62 includes a fixed block 621 fixedly installed on the outer wall of the connecting rod 618, a sliding rod 622 fixedly installed on the bottom of the fixed block 621, a sealing ring 623 fixedly installed on the end of the sliding rod 622 away from the fixed block 621, an air pipe 624 is sleeved on the outer wall of the sealing ring 623, an air blowing frame 625 is connected to the end of the air pipe 624, and a support block 626 is fixedly installed on the outer wall of the air pipe 624.

[0034] In this embodiment, when the PCBA board is coated, it is necessary to clean the dust on its surface. At this time, when the lifting mechanism 3 drives the moving mechanism 4 to move downward, the connecting rod 618 fixedly installed on the outer wall of the moving mechanism 4 drives the fixed block 621 downward, and the fixed block 621 drives the sliding rod 622 to move downward. The sliding rod 622 drives the sealing ring 623 to slide inside the air pipe 624. Since the sealing ring 623 and the air pipe 624 are sealed and sliding, under its restriction, the sealing ring 623 pushes the gas inside the air pipe 624, and blows it through the blowing frame 625 to clean the dust on the surface of the clamped PCBA board.

[0035] Furthermore, the sealing ring 623 is made of rubber, and the outer wall of the sealing ring 623 is slidably arranged with the inner wall of the air pipe 624. Under the restriction of the sealing ring 623, the gas inside the air pipe 624 can be pushed to clean the dust on the surface of the PCBA board.

[0036] In addition, the support block 626 is fixedly installed on the top surface of the processing table 1. There are two support blocks 626, which are symmetrically distributed about the center line of the top surface of the processing table 1. With the support of the support block 626, the slide rod 622 and the air pipe 624 can slide stably.

[0037] The above is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in this field without departing from the concept and principle of the present invention should fall within the scope of protection of the present invention. It should also be noted that the various components of the present invention are not limited to the above-mentioned overall application. The various technical features described in the specification of the present invention can be selected for use alone or in combination according to actual needs. Therefore, the present invention naturally covers other combinations and specific applications related to the utility model points of this case.
