Description

Technical Field

[0001] This utility model relates to the field of soldering equipment technology, and in particular to an automated intelligent spraying device for the pre-soldering process that can spray flux onto the surface of a product where soldering is required. Background Technology

[0002] Selective soldering machines are indispensable key equipment in modern high-density, high-reliability electronic assembly. Through precise positioning and parameter control, they enable high-quality soldering only where incoming materials such as circuit boards require it, effectively overcoming many limitations of wave soldering and manual soldering. They are particularly suitable for double-sided mixed-assembly boards, production scenarios containing heat-sensitive components, and small-batch, multi-variety production scenarios, significantly improving soldering quality, production efficiency, and flexibility, while reducing overall costs.

[0003] "Selectivity" is its core feature. The equipment can precisely control the soldering position, solder amount, and soldering time, and only operate on the solder joints that need to be soldered (such as through-hole component leads, connectors, heat sinks, etc.), avoiding thermal damage or solder contamination to surrounding surface mount components or other sensitive areas.

[0004] Selective soldering machines replace the limitations of manual soldering and wave soldering, solving the challenges faced by traditional wave soldering when soldering double-sided mixed-assembly boards (SMT on side A, THT on side B) (requiring complex fixtures to mask SMT components), as well as the problems of low efficiency and poor consistency of manual soldering.

[0005] For existing selective soldering equipment, the pre-soldering process usually requires spraying flux onto the product surface to improve the soldering strength in the subsequent process. However, traditional soldering equipment is mostly semi-automatic, requiring manual spraying of flux onto the product surface. This results in low flux spraying efficiency, and manual operation is prone to errors such as missed spraying and inaccurate spraying positions. Furthermore, it is impossible to monitor in real time whether the flux has been sprayed to the required soldering positions on the product surface, leading to low operational reliability.

[0006] In response, the inventor of this patent, drawing on experience, deeply considered the problems encountered in his work, reviewed a large amount of scientific research data and literature, and gradually conceived and designed this application through a novelty search to solve the relevant technical problems.

[0034] The beneficial effects of this utility model are:

[0035] Firstly, the automated intelligent spraying equipment provided in this application, in its specific implementation, during the process of the PCB board material being slowly conveyed from left to right, uses a two-dimensional moving mechanism controlled by a pre-set program to move the flux sprayer left and right and back and forth, thereby spraying flux onto a preset position on the bottom surface of the PCB board material. This facilitates subsequent soldering at the preset position on the bottom surface of the PCB board material in subsequent processes. This process is fully automated, resulting in high flux spraying efficiency and reducing the likelihood of missed spraying or inaccurate spraying positions, thus ensuring the high reliability of this application.

[0036] Secondly, by setting up the CCD camera, this application can monitor in real time whether the flux has been sprayed into place at the location to be soldered on the bottom surface of the incoming PCB board during actual use, thus enhancing the overall reliability of this application. Furthermore, by setting up the forward and backward moving component B, the CCD camera can be moved back and forth, resulting in a wider shooting range. This allows for better inspection of whether the preset location on the bottom surface of the incoming PCB board has been sprayed with flux, further improving the overall reliability of this application.

[0037] Thirdly, the PCB board clamping and conveying device described in this application, when including the front clamping and conveying member having the front support, front transmission gear, front transmission chain, front drive rotating component and multiple front lifting members for lifting the incoming PCB board, and the rear clamping and conveying member having the rear support, rear transmission gear, rear transmission chain, rear drive rotating component and multiple rear lifting members for lifting the incoming PCB board, can make it stable and reliable in use, and the PCB board material being conveyed from left to right is not easily slipped or dropped.

[0038] Fourthly, in actual use of this application, the front and rear dimensions of PCBs that require flux spraying at the preset position on the bottom surface may vary. Therefore, the front and rear moving component C can be used to control the back and front movement of the rear support according to the front and rear dimensions of the PCBs that require flux spraying at the preset position on the bottom surface. This allows the distance between the rear clamping conveyor and the front clamping conveyor to be adjusted so that they can just fit together and support the PCBs that require flux spraying at the preset position on the bottom surface, whose front and rear dimensions match the distance between them. This makes the application more flexible and adaptable to use.

[0039] Fifthly, by setting up the exhaust gas collection hood, even if the exhaust gas generated when the flux is sprayed from bottom to top is collected through the hood opening A, the collected exhaust gas can be discharged through the exhaust pipe connected to the exhaust port, making it less likely to pollute the air environment of the workshop where this application is placed. By setting up the filter hood, even if the exhaust gas generated when the flux is sprayed from bottom to top is collected through the hood opening B, the dust particles and water stains contained in the collected exhaust gas can be retained in the filter hood and intercepted, so that the exhaust gas discharged into the exhaust channel through the exhaust micropores does not contain a large amount of dust particles and water stains, so that when it is subsequently discharged through the exhaust pipe connected to the exhaust port, it is not easy to clog the connected exhaust pipe, thus extending the service life of the connected exhaust pipe.

[0091] The automated intelligent spraying device 1000 of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0092] Reference Figures 1 to 6 As shown;

[0093] The automated intelligent spraying device 1000 provided according to the embodiment of the present utility model includes a housing 10, a PCB board clamping and conveying device 20, a two-dimensional moving mechanism 30 and a flux sprayer 40.

[0094] The housing 10 has a PCB board inlet 101 at the center of its left end face and a PCB board outlet 102 at the center of its right end face, directly opposite the PCB board inlet 101. The PCB board clamping and conveying device 20 is fixed inside the housing 10 in the left-right direction, with its left and right ends extending out of the PCB board inlet 101 and the PCB board outlet 102, or correspondingly connected to the PCB board inlet 101 and the PCB board outlet 102. The two-dimensional moving mechanism 30 is fixed inside the lower part of the housing 10. The flux sprayer 40 is fixed upward on the two-dimensional moving mechanism 30 and located below the PCB board clamping and conveying device 20, so that it can move left and right and back and forth under the control of the two-dimensional moving mechanism 30.

[0095] Based on the above, it is clear that this application is mainly used as an automated intelligent spraying device 1000 in specific implementation.

[0096] Specifically, when applying this application, the application is assembled according to the structure described above, and the PCB board material that needs to be sprayed with flux at a preset position on its bottom surface is inserted into the housing 10 through the PCB board inlet 101. After being clamped at its right end by the PCB board clamping and conveying device 20, the PCB board material can be slowly conveyed from left to right under the conveying of the PCB board clamping and conveying device 20, and finally sent out from the PCB board outlet 102. During this conveying process, the flux sprayer 40 can move left and right and back and forth under the control of the two-dimensional moving mechanism 30 to spray flux at the preset welding position on the bottom surface of the PCB board material. In this way, this application can be used easily.

[0097] Clearly, the application of this application will have the following technical effects:

[0098] As the PCB board is slowly conveyed from left to right, the flux sprayer 40 is controlled by the two-dimensional moving mechanism 30 to move left and right and back and forth through the pre-set program. This allows the flux to be sprayed onto the preset soldering positions on the bottom surface of the PCB board, so that subsequent processes can solder the PCB board at the preset positions on the bottom surface. This process is fully automated, which makes the flux spraying efficiency high and reduces the likelihood of missed spraying or inaccurate spraying positions, thus making this application highly reliable.

[0099] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0100] Furthermore, in specific implementation, in accordance with... Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, the two-dimensional moving mechanism 30 includes a left-right moving component A301 and a front-back moving component A302;

[0101] The left-right moving component A301 is fixedly disposed in the lower part of the housing 10 in the left-right direction; the front-back moving component A302 is fixedly disposed on the left-right moving component A301 in the front-back direction, so that it can move left and right under the control of the left-right moving component A301; the flux sprayer 40 is fixedly disposed on the front-back moving component A302, so that it can move back and forth under the control of the front-back moving component A302.

[0102] Therefore, under the combined action of the left-right moving component A301 and the front-back moving component A302, the flux sprayer 40 can be driven to move left and right and back and forth to spray flux onto the preset soldering position on the bottom surface of the PCB board. In this way, the flux sprayer 40 of this application can be used flexibly, and after its movement trajectory is set in advance by the software program, its spraying position can be made accurate.

[0103] Furthermore, in the specific implementation, we will continue to refer to... Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, this application also includes a CCD camera 50 for capturing and detecting the location where flux needs to be sprayed on the bottom surface of the PCB board material output from the PCB board outlet 102.

[0104] The CCD camera 50 is fixed upward on the right end face of the housing 10 and located below the PCB board outlet 102.

[0105] Therefore, when the CCD camera 50 is activated, the bottom surface of the PCB board can be photographed and detected by the CCD camera 50 when the PCB board is slowly conveyed out from the PCB board outlet 102, so as to check whether flux has been sprayed at the preset position on the bottom surface of the PCB board.

[0106] Furthermore, by setting up the CCD camera 50, this application can monitor in real time whether the flux has been sprayed into place at the position to be soldered on the bottom surface of the incoming PCB board during actual use, thus making the overall reliability of this application stronger.

[0107] Furthermore, in this technical solution, it is still in comparison with... Figure 1 and Figure 2 As shown, according to one embodiment of the present invention, this application also includes a forward and backward moving member B60;

[0108] The forward and backward moving component B60 is fixedly mounted on the right end face of the housing 10 in the forward and backward direction and is located directly below the PCB board outlet 102; the CCD camera 50 is fixedly mounted on the forward and backward moving component B60 so that it can move forward and backward under the control of the forward and backward moving component B60.

[0109] Therefore, by setting the forward and backward moving component B60, the CCD camera 50 can be driven to move forward and backward, so that its shooting range is wider, so that it can better check whether the preset position on the bottom surface of the incoming PCB board has been sprayed with flux, making the overall reliability of this application better.

[0110] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0111] Furthermore, in specific implementation, according to one embodiment of this utility model, comparing... Figures 3 to 6 As shown, the PCB board clamping and conveying device 20 includes a front clamping and conveying member 201 and a rear clamping and conveying member 202 arranged in the left-right direction.

[0112] The front clamping conveyor 201 and the rear clamping conveyor 202 define a clamping gap for the incoming PCB board. Under the joint clamping of the front clamping conveyor 201 and the rear clamping conveyor 202, the incoming PCB board is conveyed from left to right.

[0113] Therefore, by setting the front clamping conveyor 201 and the rear clamping conveyor 202, the PCB board material can be clamped and slowly conveyed from left to right under their joint clamping and conveying, so that the PCB board material is not easy to slip and fall when it is clamped and conveyed from left to right, thus making the conveying stable and reliable.

[0114] Furthermore, in this technical solution, we continue to compare... Figures 3 to 6 As shown, according to one embodiment of the present utility model, the front clamping and conveying member 201 includes a front support 2011, a front transmission gear 2012, a front transmission chain 2013, a front drive rotating member 2014, and a plurality of front lifting members 2015 for lifting the incoming PCB board.

[0115] The front bracket 2011 is arranged in a left-right direction, with a front rotating bearing 2016 vertically arranged at each of its left and right ends; a front drive gear 2012 is respectively fitted onto the upper end of each of the two front rotating bearings 2016; a front drive chain 2013 is rotatably fitted onto the two front drive gears 2012; the front drive rotating component 2014 is used to control at least one of the front rotating bearings 2016 to actively rotate, thereby driving the two front drive gears 2012 and the front drive chain 2013 fitted onto them to rotate. Specifically... The front drive rotating component 2014 can be a front drive rotating motor, so that its rotating shaft is coaxially connected or meshed with one of the front rotating bearings 2016, so as to drive one of the front rotating bearings 2016 to rotate actively, thereby driving the two front transmission gears 2012 and the front transmission chain 2013 sleeved on them to rotate; the plurality of front lifting components 2015 are preferably evenly fixed on the side of the front transmission chain 2013, and PCB board receiving front lifting buckles 20151 are respectively provided on the side opposite to the front transmission chain 2013.

[0116] Furthermore, in specific implementation, it is still necessary to refer to... Figures 3 to 6As shown, according to one embodiment of the present invention, the rear clamping and conveying component 202 includes a rear support 2021, a rear transmission gear 2022, a rear transmission chain 2023, a rear drive rotating component 2024, and a plurality of rear lifting components 2025 for lifting the incoming PCB board.

[0117] The rear support 2021 is arranged in a left-right direction, with a rear rotating bearing 2026 vertically arranged at each of its left and right ends; a rear drive gear 2022 is respectively fitted onto the upper end of each of the two rear rotating bearings 2026; a rear drive chain 2023 is rotatably fitted onto the two rear drive gears 2022; the rear drive rotating component 2024 is used to control at least one of the rear rotating bearings 2026 to actively rotate, thereby driving the two rear drive gears 2022 and the rear drive chain 2023 fitted onto them to rotate. Specifically... The rear drive rotating component 2024 can be a rear drive rotating motor, so that its rotating shaft is coaxially connected or meshed with one of the rear rotating bearings 2026, so as to drive one of the rear rotating bearings 2026 to rotate actively, thereby driving the two rear transmission gears 2022 and the rear transmission chain 2023 sleeved on them to rotate; the plurality of rear lifting components 2025 are preferably evenly fixed on the side of the rear transmission chain 2023, and PCB board receiving lifting buckles 20251 are respectively provided on the side opposite to the rear transmission chain 2023.

[0118] Furthermore, the rotation direction of the front drive chain 2013 is opposite to that of the rear drive chain 2023, and their opposite sides are synchronously driven from left to right.

[0119] Therefore, it is clear that under the joint drive of the front drive rotating component 2014 and the rear drive rotating component 2024, the rotation direction of the front drive chain 2013 is opposite to that of the rear drive chain 2023, and the rotation frequency is the same, so that their opposite sides are synchronously driven from left to right. At this time, the multiple front lifting components 2015 and multiple rear lifting components 2025 that are opposite to each other can be driven synchronously from left to right. In this way, the multiple PCB board material front lifting buckles 20151 and multiple PCB board material rear lifting buckles 20251 that are opposite to each other can be used to jointly fasten and lift the PCB board material that needs to be sprayed with flux at the preset welding position on its bottom surface, and drive it to be transported from left to right.

[0120] This is understandable:

[0121] On the one hand, when multiple front-mounted PCB board lifting buckles 20151 and multiple rear-mounted PCB board lifting buckles 20251, which are positioned opposite each other, jointly hold and lift the PCB board material that needs to be sprayed with flux at the preset soldering position on its bottom surface, the held and lifted PCB board material is indeed not easy to slip off and fall. This is because the PCB board material is generally square in structure, and its front and rear edges are parallel so that its front and rear dimensions remain unchanged. The front and rear distance between the multiple front-mounted PCB board lifting buckles 20151 and multiple rear-mounted PCB board lifting buckles 20251 is also fixed. In this way, the multiple front-mounted PCB board lifting buckles 20151 and multiple rear-mounted PCB board lifting buckles 20251 can indeed firmly hold and lift the PCB board material and prevent it from slipping off and falling.

[0122] On the other hand, when the multiple front lifting members 2015 and the multiple rear lifting members 2025 that are opposite each other are driven synchronously from left to right, the multiple front lifting buckles 20151 and the multiple rear lifting buckles 20251 that are opposite each other can lift the PCB board material and drive the lifted PCB board material to be transported from left to right, so as to realize the spraying of flux on the preset welding position on the bottom surface from right to left.

[0123] Therefore, it can be clearly understood that the PCB board clamping and conveying device 20 described in this application, when including the front clamping and conveying member 201 having the front support 2011, front transmission gear 2012, front transmission chain 2013, front drive rotating member 2014 and multiple front lifting members 2015 for lifting incoming PCB boards, and the rear clamping and conveying member 202 having the rear support 2021, rear transmission gear 2022, rear transmission chain 2023, rear drive rotating member 2024 and multiple rear lifting members 2025 for lifting incoming PCB boards, can be used stably and reliably.

[0124] Preferably, in this technical solution, compared with Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, the PCB board clamping and conveying device 20 further includes a front-to-back moving component C203;

[0125] The front-to-back moving component C203 is fixedly installed in the upper part of the housing 10; the rear support 2021 is installed at the bottom of the front-to-back moving component C203 so that it can move back and forth under the control of the front-to-back moving component C203, so that the distance between the rear clamping and conveying component 202 and the front clamping and conveying component 201 is adjustable.

[0126] Therefore, it can be clearly understood that in actual use of this application, the front and rear dimensions of PCB boards that require flux spraying at the preset position on the bottom surface will have different specifications. Thus, the front and rear moving component C203 can be used to control the front and rear movement of the rear support 2021 according to the front and rear dimensions of the PCB board that requires flux spraying at the preset position on the bottom surface. This allows the distance between the rear clamping conveyor 202 and the front clamping conveyor 201 to be adjusted so that it can just fit and support the PCB board that requires flux spraying at the preset position on the bottom surface, whose front and rear dimensions are adapted to the distance between them. This makes the application more flexible to use and more adaptable.

[0127] Furthermore, preferably, in this technical solution, the comparison continues. Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, this application also includes an exhaust gas collection hood 70 for collecting spray exhaust gas;

[0128] The exhaust gas collection hood 70 is fixed inside the upper part of the housing 10 and covers the upper part of the PCB board clamping and conveying device 20. Its bottom is formed as a hood opening A and its top is provided with an exhaust port 701.

[0129] Thus, by setting up the exhaust gas collection hood 70, even if the exhaust gas generated when the flux is sprayed from bottom to top is collected through the hood opening A, the collected exhaust gas can be discharged through the exhaust pipe connected to the exhaust port 701, so that it is not easy to pollute the air environment of the workshop where this application is placed.

[0130] Meanwhile, based on the above embodiments, the following is still in comparison. Figure 3 and Figure 5 As shown, according to one embodiment of the present invention, this application also includes a filter cover 80 for filtering dust particles and water stains in the spray exhaust gas;

[0131] The filter cover 80 is fixed inside the exhaust gas collection cover 70 and has a certain gap with the exhaust gas collection cover 70 to form an exhaust flow channel; the outer wall of the filter cover 80 is provided with an exhaust micro hole 801 that extends through the exhaust flow channel, and the bottom of the filter cover 80 is formed into a cover opening B that covers the upper part of the PCB board clamping and conveying device 20.

[0132] Thus, by setting the filter cover 80, even if the exhaust gas generated when the flux is sprayed from bottom to top is collected through the cover opening B, the dust particles and water stains contained in the collected exhaust gas can be retained in the filter cover 80 and intercepted. This makes the exhaust gas discharged into the exhaust channel through the exhaust micro-hole 801 basically free of a large amount of dust particles and water stains. As a result, when the exhaust gas is discharged through the exhaust pipe connected to the exhaust port 701, it is not easy to clog the connected exhaust pipe, thus making the connected exhaust pipe have a long service life.

[0133] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be further improved.

[0134] It should be added that, in specific implementation, according to the automated intelligent spraying device 1000 provided in the embodiment of this utility model, the left and right moving component A301, the front and back moving component A302, the front and back moving component B60 and the front and back moving component C203 are all preferably screw drive linear modules, chain drive linear modules, belt drive linear modules or cylinder drive linear modules, etc., which are common in the prior art, so their details are not described here.

[0135] Furthermore, in specific implementation, it is still necessary to refer to... Figure 3 and Figure 5 As shown, in order to improve the stability of the rear support 2021 moving back and forth, two front and rear moving components C203 are provided along the front and rear direction. The left and right ends of the rear support 2021 are respectively installed at the bottom of the two front and rear moving components C203, so that when the two front and rear moving components C203 work synchronously, the rear support 2021 can be driven to move back and forth stably, so that the distance between the rear clamping conveyor 202 and the front clamping conveyor 201 is adjustable.

[0136] Furthermore, it is necessary to add that, in specific implementation, comparison should be made with... Figure 1 and Figure 2 As shown, according to the embodiment of the present utility model, the automated intelligent spraying device 1000 is provided with height-adjustable feet 103 at the four corners of the bottom of the housing 10, so as to control the stability of the device when placed on the ground by adjusting the height of the multiple height-adjustable feet 103. The top of the housing 10 is provided with an opening 104 to accommodate an external exhaust pipe that is plugged into it or passes through it and is inserted into the exhaust port 701.

[0137] Other embodiments, etc., will not be described here.

[0138] In summary, the automated intelligent spraying device 1000 provided in this application, in its specific implementation, allows the flux sprayer 40 to move left and right and back and forth via the two-dimensional moving mechanism 30 during the slow conveying of the PCB board material from left to right, through a pre-set program. This enables the spraying of flux onto the preset soldering positions on the bottom surface of the PCB board material, facilitating subsequent soldering operations at these positions. This fully automated process results in high flux spraying efficiency and minimizes the risk of missed spraying or inaccurate spraying positions, thus ensuring the high reliability of this application.

[0139] Furthermore, by setting up the CCD camera 50, this application can monitor in real time whether the flux has been sprayed into place at the location to be soldered on the bottom surface of the incoming PCB board during actual use, thus enhancing the overall reliability of this application. By setting up the forward and backward moving component B60, the CCD camera 50 can be moved back and forth, resulting in a wider shooting range. This allows for better inspection of whether the preset location on the bottom surface of the incoming PCB board has been sprayed with flux, further improving the overall reliability of this application.

[0140] Furthermore, the PCB board clamping and conveying device 20 described in this application, when including the front clamping and conveying member 201 having the front support 2011, front drive gear 2012, front drive chain 2013, front drive rotating member 2014 and multiple front lifting members 2015 for lifting incoming PCB boards, and the rear clamping and conveying member 202 having the rear support 2021, rear drive gear 2022, rear drive chain 2023, rear drive rotating member 2024 and multiple rear lifting members 2025 for lifting incoming PCB boards, makes it stable and reliable in use, and the PCB board material being conveyed from left to right is not easily slipped or dropped.

[0141] Furthermore, in actual use of this application, the front and rear dimensions of PCBs that require flux spraying at the preset position on the bottom surface may vary. Therefore, the front and rear dimensions of the PCBs that require flux spraying at the preset position on the bottom surface can be adapted to the front and rear dimensions of the PCBs that require flux spraying at the preset position on the bottom surface. This allows the front and rear movement of the rear support 2021 to be controlled by the front and rear moving component C203, so that the distance between the rear clamping conveyor 202 and the front clamping conveyor 201 can be adjusted to fit and support the PCBs that require flux spraying at the preset position on the bottom surface, whose front and rear dimensions are adapted to the distance between them. This makes the application more flexible and adaptable to use.

[0142] Furthermore, by setting up the exhaust gas collection hood 70, even if the exhaust gas generated when the flux is sprayed from bottom to top is collected through the hood opening A, the collected exhaust gas can be discharged through the exhaust pipe connected to the exhaust port 701, making it less likely to pollute the air environment of the workshop where this application is placed. By setting up the filter hood 80, even if the exhaust gas generated when the flux is sprayed from bottom to top is collected through the hood opening B, the dust particles and water stains contained in the collected exhaust gas can be retained in the filter hood 80 and intercepted, so that the exhaust gas discharged into the exhaust channel through the exhaust micropores 801 does not contain a large amount of dust particles and water stains, so that when it is subsequently discharged through the exhaust pipe connected to the exhaust port 701, it is less likely to clog the connected exhaust pipe, thus extending the service life of the connected exhaust pipe.

[0143] Furthermore, the automated intelligent spraying device 1000 provided in this application is indeed highly practical and has excellent performance, which makes this application inherently valuable for market promotion and will certainly be very popular and effectively popularized.
