Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to an automatic spraying device for plate parts. Background Art

[0002] Panels are a common structural component with a wide range of applications in modern industrial development. Among them, circuit boards, also known as printed circuit boards (PCBs), are one of the most common components in the electronics field. They are a key component in modern electronic devices, primarily providing structural support and connecting various electronic components through pre-designed pathways. Therefore, they are widely used in consumer electronics, home appliances, industrial control, communications equipment, medical equipment, automobiles, and other fields. For example, in the field of home appliances, air conditioners are equipped with multiple circuit boards with different functions, such as the main control board, power board, display board, and driver board, which are primarily used to control and coordinate the various functions of the air conditioning system.

[0003] In the current circuit board production, it is generally necessary to insert electronic components first, and then solder them firmly after the insertion is completed. However, due to various environmental factors, electronic components are often not firmly soldered and oxidation reactions occur at the soldering points, seriously affecting the quality of the circuit board. Therefore, in the actual production process, it is generally necessary to spray flux on the soldering points of the circuit board in advance (flux is a common chemical substance in the welding process that can help and promote the welding process, and at the same time has a protective effect and can prevent oxidation reactions).

[0004] In the existing technology, the production process of spraying flux on circuit boards is all done manually. This manual operation method not only has low production efficiency and affects the production rhythm, but also often causes phenomena such as partial coating and missing coating, which affects production quality.

[0038] The present utility model provides an automatic spraying device for panels, which can be used for automatic spraying of panels 1, such as automatic spraying of flux on circuit boards. Of course, it can also be used in the automatic spraying of other similar products or similar sprays. There is no limitation here. The following description will be made using the automatic spraying of flux on circuit boards as an example.

[0039] like Figure 1 、 Figure 2 、 Figure 3As shown, the automatic panel spraying device includes a loading mechanism 2, a positioning mechanism 3 and a spraying mechanism 4; wherein, the loading mechanism 2 is a conveyor belt assembly that can transport circuit boards, such as a common flat conveyor belt, a double-sided rack conveyor belt, etc., which can be used to realize the loading and transportation of the circuit boards, and a spraying station is provided on the conveyor belt assembly. When the circuit board is transported to the spraying station, the device will start the flux spraying action at this position; the positioning mechanism 3 includes an entrance block 31 and an in-place block 32. Specifically, the entrance block 31 is arranged in front of the entrance of the spraying station (the entrance front referred to here refers to the left side of the conveyor belt spraying station in the figure, the position that has not entered the spraying station), the entrance block 31 can block the circuit board from entering the spraying station; and the in-place block 32 is arranged at the exit of the spraying station At the entrance (i.e., the rightmost side of the conveyor belt spraying station in the figure), the in-place block 32 can block the conveying movement of the circuit board; the blocking action of the entrance block 31 and the in-place block 32 can be specifically by sucking or clamping the circuit board to prevent it from continuing to move forward, or by blocking the forward direction of the circuit board to prevent it from continuing to move forward, etc., or even by stopping the conveyor belt assembly to prevent the circuit board from continuing to move forward, etc., which is not limited here; the spraying mechanism 4 is arranged at the spraying station, and when the circuit board is conveyed to the spraying station, the spraying mechanism 4 can spray flux onto the circuit board to complete the automatic spraying of flux on the circuit board; when the flux spraying is completed, the in-place block 32 stops the blocking action, and the circuit board continues to be conveyed for unloading.

[0040] The automatic panel spraying device adopting the above structure can realize automatic loading, automatic spraying and automatic unloading during the circuit board flux spraying process through the mutual cooperation of the feeding mechanism 2, the positioning mechanism 3 and the spraying mechanism 4, realize the fully automated operation of flux spraying, realize continuous production, and improve production efficiency; at the same time, it can avoid the occurrence of partial coating, missing coating and other phenomena caused by manual application of flux, and can improve production quality; in addition, by arranging the entrance block 31 and the in-place block 32 before and after the spraying station, it can be ensured that there is only one circuit board in the spraying station area, which can improve the reliability of the automatic panel spraying device and further improve the spraying quality.

[0041] In some embodiments, the entrance block 31 and / or the in-place block 32 are retractable components, which can block the forward direction of the circuit board when extended, thereby preventing the circuit board from moving on the conveyor belt assembly; specifically, only the entrance block 31 can be a retractable component, or only the in-place block 32 can be a retractable component, or as shown in this embodiment, both the entrance block 31 and the in-place block 32 can be retractable components; the retractable components can be arranged above, below, on the left or right side of the circuit board, etc., as long as they can block the forward direction of the circuit board and prevent the circuit board from moving on the conveyor belt assembly when extended, and there is no limitation here.

It not only has a simple structure and is convenient for maintenance and replacement, but also has a better blocking effect and more accurate blocking positioning, which helps to further improve the spraying quality.

[0043] In some embodiments, a first photoelectric sensor 33 is also provided at the entrance block 31, and the first photoelectric sensor 33 can detect the transmission status of the circuit board on the conveyor belt; when the first photoelectric sensor 33 detects that the circuit board has passed and has completed passing through the entrance block 31, the first photoelectric sensor 33 transmits a signal, and the automatic panel spraying device controls the entrance block 31 and the in-place block 32 to extend quickly, and the in-place block 32 positions the circuit board on the spraying station for spraying, and at the same time, the entrance block 31 blocks the next circuit board from entering the spraying station in advance; after the spraying mechanism 4 completes the spraying action, the automatic panel spraying device controls the in-place block 32 to retract, and the circuit board that has completed the flux spraying continues to be conveyed and unloaded.

[0044] The automatic panel spraying device adopting the above structure can more accurately control the blocking action of the entrance block 31 and the in-place block 32 by setting a first photoelectric sensor 33 at the entrance block 31, thereby improving the reliability of the automatic panel spraying device, thereby improving production efficiency and improving production quality.

[0045] In some embodiments, a second photoelectric sensor 34 is further provided at the in-place block 32, and the second photoelectric sensor 34 can detect the conveying status of the circuit board on the conveyor belt; when the second photoelectric sensor 34 detects that a circuit board that has completed flux spraying has passed and has completed passing through the in-place block 32, the second photoelectric sensor 34 transmits a signal, and the automatic panel spraying device controls the entrance block 31 to retract, and the next circuit board to be sprayed is conveyed and moved into the spraying station for spraying.

[0046] The automatic panel spraying device adopting the above structure can more accurately control the blocking action of the entrance block 31 by setting a second photoelectric sensor 34 at the in-place block 32, thereby improving the reliability of the automatic panel spraying device, thereby improving production efficiency and improving production quality.

[0047] In some embodiments, the loading mechanism 2 is a double-sided rack conveyor belt 21 adapted to the circuit board. Specifically, in this embodiment, the double-sided rack conveyor belt 21 has a hollow structure in the middle, and racks are embedded on both sides of the hollow structure. The width of the racks on both sides is adapted to the circuit board, and the racks are engaged with a driving device (such as a gear or sprocket) to achieve precise transmission movement.

[0048] The automatic panel spraying device adopts the above structure and adopts a double-sided rack conveyor belt 21 adapted to the circuit board as the loading mechanism 2. The circuit board is placed on the racks on both sides of the double-sided rack conveyor belt 21, which can achieve precise positioning of the circuit board during the loading and conveying process, reduce the occurrence of deviation and slipping, and improve the stability and reliability of the automatic panel spraying device; at the same time, the hollow structure is not prone to problems such as stains on the conveyor belt surface and dirt on the circuit board during spraying, which is cleaner and tidier, and can improve production quality.

[0049] In some embodiments, as Figure 4 、 Figure 5 As shown, the spraying mechanism 4 includes a spray head 41 and a first driving component 42; Figure 6 As shown, the nozzle 41 is regularly provided with a number of small nozzles, which can evenly spray the flux onto the circuit board in the form of a spray, and the spraying effect is better; the first driving component 42 can control the nozzle 41 to move laterally in the spraying station (i.e., forward and backward or left and right, left and right in this embodiment), thereby gradually completing the spraying action of the circuit board.

[0050] The automatic panel spraying device with the above structure can achieve uniform spraying of the flux through the cooperation of the nozzle 41 and the first driving component 42, with good spraying effect, simple structure, and easy maintenance and replacement.

[0051] In some embodiments, the spraying mechanism 4 further includes a second driving component 43 , which can control the longitudinal movement of the spray head 41 to move closer to or away from the circuit board in the vertical direction.

[0052] In the automatic panel spraying device adopting the above structure, when there is no need to perform spraying, the second driving component 43 controls the nozzle 41 to move upward, away from the circuit board; when spraying is required, the second driving component 43 controls the nozzle 41 to move downward, close to the circuit board, thereby further improving the operating convenience and reliability of the automatic panel spraying device.

[0053] In some embodiments, as Figure 5 As shown, the spraying mechanism 4 also includes a spraying template 44, which is arranged between the nozzle 41 and the circuit board, and the spraying template 44 is also provided with a hollow pattern 441 adapted to the spraying position of the circuit board. When the nozzle 41 passes over the spraying template 44 and sprays, the flux passes through the hollow pattern 441, thereby achieving flux spraying at a specific position on the circuit board; preferably, the spraying template 44 is made of corrosion-resistant material.

[0054] The automatic panel spraying device with the above structure can accurately control the spraying position on the circuit board through the setting of the spraying template 44, thereby improving production quality.

[0055] In some embodiments, the spray template 44 is made of stainless steel. Stainless steel has good strength, corrosion resistance and a long service life, and is a more preferred choice after comprehensive consideration of use effect and cost.

[0056] In some embodiments, as Figure 7 、 Figure 8 As shown, the position on the spray template 44 that does not require spraying is a concave spray recovery platform 442, which can be used to collect excess flux, and the spray template 44 is also provided with at least one spray recovery port 443 connected to the spray recovery platform 442 and capable of flowing out the flux. In this embodiment, there is one in the front and one in the back.

[0057] The automatic panel spraying device using the above structure can recover excess flux during the spraying process for secondary use through the provision of the spray recovery station 442 and the spray recovery port 443, thereby avoiding material waste and reducing production costs.

[0058] In some embodiments, the spraying mechanism 4 also includes a detection mechanism 45 arranged above the spraying station, and the detection mechanism 45 can be used to detect whether the circuit board is sprayed qualified; in this embodiment, the detection mechanism 45 is an industrial camera, which captures the image of the circuit board and compares it with the template to detect whether the spraying is qualified. If it is unqualified, an alarm will be triggered, and the employee will need to confirm the reset before continuing to work. If it is qualified, the circuit board will continue to be transported and unloaded.

[0059] The automatic panel spraying device with the above structure can detect the spraying effect of the circuit board through the setting of the detection mechanism 45, thereby improving production quality.

[0060] In some embodiments, as Figure 2 、 Figure 3 、 Figure 4 As shown, the spraying station is covered with a transparent protective cover 5. For example, in this embodiment, the transparent protective cover 5 is made of a transparent acrylic plate.

[0061] The automatic panel spraying device with the above structure can achieve physical isolation of the spraying station and prevent the spray from splashing through the provision of the transparent protective cover 5, and can also achieve visualization of the spraying station at the same time.

[0062] In some embodiments, as Figure 1 、 Figure 2 、 Figure 3 As shown, the automatic panel spraying device also includes a PLC touch screen controller 6, which is electrically connected to the feeding mechanism 2, the positioning mechanism 3 and the spraying mechanism 4, and can receive signals from the feeding mechanism 2, the positioning mechanism 3 and the spraying mechanism 4, and give control signals to control the corresponding actions of the feeding mechanism 2, the positioning mechanism 3 and the spraying mechanism 4.

[0063] The automatic panel spraying device using the above structure can realize the switch control of the device, statistical display of production status, etc. by setting a PLC touch screen controller 6 electrically connected to the feeding mechanism 2, positioning mechanism 3 and spraying mechanism 4, human-computer interaction, higher convenience of operation, and can improve production efficiency.
