[0030] The present invention provides the following description with reference to the accompanying drawings to assist in a comprehensive understanding of various embodiments of the present invention as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be considered as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present invention.

[0031] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0033] An embodiment of the present invention provides a circuit board processing device with a spray device, such as Figure 1-5 As shown, it includes a conveying device 100, a spraying device 200 and a swinging device 300. The conveying device 100 includes a plurality of conveying rollers 110 arranged along the conveying direction, and the circuit board is used to be placed on the conveying rollers 110. As the conveying rollers 110 rotate, the circuit board moves along the conveying direction. The spraying device 200 includes a plurality of upper spraying pipes 210 located above the conveying rollers 110 and a plurality of lower spraying pipes 220 located below the conveying rollers 110. When performing a spraying operation, the upper spraying pipes 210 are located above the circuit board, and the lower spraying pipes 220 are located below the circuit board. The upper spraying pipes 210 and the lower spraying pipes 220 are both fixed with nozzles 230 for spraying liquid medicine onto the circuit board, wherein the nozzles 230 on the upper spraying pipes 210 are used to spray liquid medicine downward, and the nozzles 230 on the lower spraying pipes 220 are used to spray liquid medicine upward. The upper spray pipe 210 and the lower spray pipe 220 are both connected to the swing device 300, and the swing device 300 is used to drive the upper spray pipe 210 and the lower spray pipe 220 to reciprocate along the axial direction of the conveying roller 110. The axial direction of the conveying roller 110 is perpendicular to the conveying direction. As the upper spray pipe 210 and the lower spray pipe 220 reciprocate, the nozzles 230 on the upper spray pipe 210 and the lower spray pipe 220 will correspondingly change the position of spraying the solution onto the circuit board, so that the solution can be sprayed more evenly, so that the chemical reaction on the circuit board is relatively uniform, thereby improving the quality of the circuit board.

[0034] In this embodiment, two groups of swing devices 300 can be provided to drive the upper spray pipe 210 and the lower spray pipe 220 to reciprocate along the axial direction of the conveying roller 110, so that the upper spray pipe 210 and the lower spray pipe 220 can move asynchronously. Of course, one group of swing devices 300 can also be provided to drive the upper spray pipe 210 and the lower spray pipe 220 to move synchronously.

[0035] In this embodiment, the axial direction of the upper spray pipe 210 and the axial direction of the lower spray pipe 220 can be parallel to the conveying direction, form an acute angle or be perpendicular to it. Considering the convenience of the overall structural arrangement, the axial direction of the upper spray pipe 210 and the axial direction of the lower spray pipe 220 are preferably set to be perpendicular to the conveying direction. Accordingly, the nozzles 230 on the upper spray pipe 210 are distributed along its axial direction, and the nozzles 230 on the lower spray pipe 220 are also distributed along its axial direction. The spacing between two adjacent nozzles 230 can be equal to the distance that the swing device 300 drives the upper spray pipe 210 and the lower spray pipe 220 to move along the axial direction of the conveying roller 110, so as to overcome the problem of uneven spraying of the liquid medicine caused by the spacing between the two adjacent nozzles 230, thereby further improving the uniformity of liquid medicine spraying.

[0036] In some embodiments, Figure 1-5 As shown, the spray device 200 also includes an upper connecting pipe 240 and a lower connecting pipe 250 extending along the conveying direction, the upper connecting pipe 240 is connected to the upper spray pipe 210 and is used to convey medicine to the upper spray pipe 210, the lower connecting pipe 250 is connected to the lower spray pipe 220 and is used to convey medicine to the lower spray pipe 220, the upper connecting pipe 240 and the lower connecting pipe 250 are both connected to the swing device 300, and the swing device 300 is used to drive the upper connecting pipe 240 and the lower connecting pipe 250 to reciprocate along the axial direction of the conveying roller 110, thereby driving the upper spray pipe 210 and the lower spray pipe 220 to reciprocate along the axial direction of the conveying roller 110.

[0037] The upper spray pipe 210 and the lower spray pipe 220 both need to be supplied with liquid medicine from an external pipeline to ensure continuous liquid medicine spraying. The upper connecting pipe 240 and the lower connecting pipe 250 of this embodiment not only serve as liquid medicine delivery pipes, but also respectively connect the swing device 300 and the corresponding spray pipe to transmit the driving force of the swing device 300, which simplifies the overall structure and facilitates the configuration of the liquid medicine supply pipeline.

[0038] Furthermore, the swing device 300 includes a connection seat 310 and a swing drive assembly 320, wherein the connection seat 310 is connected to the upper connection pipe 240 and the lower connection pipe 250 respectively, and the swing drive assembly 320 is connected to the connection seat 310 and is used to drive the connection seat 310 to reciprocate along the axial direction of the conveying roller 110. The connection seat 310 of this embodiment connects the upper connection pipe 240 and the lower connection pipe 250 as a whole, so that the upper connection pipe 240 and the lower connection pipe 250 are linked, and accordingly, the upper spray pipe 210 and the lower spray pipe 220 can move synchronously along the axial direction of the conveying roller 110, so as to better control the spraying position of the liquid medicine, and the driving force is provided by the same swing drive assembly 320, which can simplify the structural configuration.

[0039] The connection seat 310 may be located in the middle of the upper connection tube 240 and the lower connection tube 250. Considering that the upper connection tube 240 and the lower connection tube 250 are both relatively long, two sets of connection seats 310 and swing drive components 320 may be provided. The two connection seats 310 are respectively located at the two ends of the upper connection tube 240 and the lower connection tube 250 to respectively connect the two ends of the upper connection tube 240 and the lower connection tube 250. The two swing drive components 320 will respectively drive the two connection seats 310 to synchronously reciprocate along the axial direction of the conveying roller 110. On the one hand, this can provide a greater driving force to be sufficient to drive the entire mechanism to move along the axial direction of the conveying roller 110. On the other hand, this prevents the upper connection tube 240 and the lower connection tube 250 from being deflected in position during the movement, thereby ensuring that the upper connection tube 240 and the lower connection tube 250 can stably reciprocate along the axial direction of the conveying roller 110.

[0040] Furthermore, Figure 5 , Figure 6 and Figure 7 As shown, the connection seat 310 is provided with a liquid inlet channel 311, one end of the liquid inlet channel 311 is used to connect to the external liquid inlet pipe 270, and the other end can be communicated with the upper connecting pipe 240, or communicated with the lower connecting pipe 250, or communicated with both the upper connecting pipe 240 and the lower connecting pipe 250. The liquid inlet pipe 270 is used to transport liquid medicine to the connection seat 310, and the liquid medicine enters the corresponding upper connecting pipe 240 and / or lower connecting pipe 250 through the liquid inlet channel 311 to realize the transportation of the liquid medicine.

[0041] In this embodiment, both ends of the liquid inlet channel 311 form openings on the connecting seat 310, and the liquid inlet pipe 270, the upper connecting pipe 240 and the lower connecting pipe 250 can be inserted into the openings, which not only realizes the fixed connection with each other, but also realizes the connection of the medicine delivery pipeline.

[0042] In some embodiments, Figure 2-6 As shown, the swing device also includes a guide rail 330 extending along the axial direction of the conveying roller 110, and the connecting seat 310 is slidably matched with the guide rail 330, which can guide the connecting seat 310 to stably move along the axial direction of the conveying roller 110. At the same time, more options are provided for the specific structure of the swing drive component 320, and the driving force of the swing drive component 320 in other directions will not cause the movement of the connecting seat 310 to be positionally deviated.

[0043] In this embodiment, a slider 312 extending along the axial direction of the conveying roller 110 may be provided on the connecting seat 310 , and a guide rail groove matching the slider 312 may be provided on the guide rail 330 . The slider 312 is disposed in the guide rail groove and slides along the guide rail groove.

[0044] In some embodiments, Figure 2-5As shown, the swing drive assembly 320 includes a drive mechanism 321, a rotating rod 322, an eccentric wheel 323 and a swing shaft 324. The drive mechanism 321 is connected to the rotating rod 322 and is used to drive the rotating rod 322 to rotate. The eccentric wheel 323 is fixed to the end of the rotating rod 322. When the rotating rod 322 rotates, the eccentric wheel 323 rotates eccentrically relative to the rotating rod 322. In a default state, the swing shaft 324 extends along the axial direction of the conveying roller 110, and the two ends of the swing shaft 324 are rotatably connected to the eccentric wheel 323 and the connecting seat 310 respectively. The rotation axis of the eccentric wheel 323, the rotation axis of the swing shaft 324 relative to the eccentric wheel 323, and the rotation axis of the swing shaft 324 relative to the connecting seat 310 are parallel to each other, and the rotation axis of the eccentric wheel 323 is perpendicular to the axial direction of the conveying roller 110. Therefore, the eccentric wheel 323 and the swing shaft 324 rotate on the same or parallel planes. This rotation exerts a force on the swing shaft 324. Since the connecting seat 310 and the guide rail 330 slide together, the swing shaft 324 can push or pull the connecting seat 310 to reciprocate along the axial direction of the conveying roller 110, forming an effect similar to that of an engine piston rod.

[0045] Compared with directly driving the connecting seat 310 to reciprocate along the axial direction of the conveying roller 110 through a driving mechanism, the driving structure of this embodiment has a shorter width in the axial direction of the conveying roller 110, thereby reducing space occupancy and allowing more space to be used to configure the conveying device and the spraying device.

[0046] In this embodiment, the driving mechanism 321 may include a motor, which drives the rotating rod 322 to rotate, and the rotating rod 322 may extend along the conveying direction. A collar may be provided at the end of the swing shaft 324, which is sleeved on the eccentric wheel 323 and can rotate relative to the eccentric wheel 323 to achieve a rotational connection between the swing shaft 324 and the eccentric wheel 323.

[0047] Further, such as Figure 1-5 As shown, the circuit board processing equipment with a spray device also includes a shell 10, and the conveying device 100, the spray device 200 and the connecting seat 310 are all arranged in the shell 10, which plays a role in dust protection for the conveying device 100, the spray device 200 and the connecting seat 310, and can also reduce the splashing of the medicine.

[0048] The driving mechanism 321, the rotating rod 322 and the eccentric wheel 323 are all arranged on the outside of the shell 10. On the one hand, this can reduce the occupation of the internal space of the shell 10, so that the space inside the shell 10 can accommodate a larger circuit board. On the other hand, it prevents the medicine from splashing onto the driving mechanism 321, thereby ensuring the stable operation of the driving mechanism 321.

[0049] Accordingly, the housing 10 is provided with a perforation, and the swing shaft 324 is provided in the perforation, so that the two ends of the swing shaft 324 can be rotatably connected to the eccentric wheel 323 and the connecting seat 310 respectively. At the same time, the swing shaft 324 is also provided with a water blocking mechanism 340 for limiting the outflow of the medicine from the perforation, so that the medicine will not flow out of the housing 10 through the perforation, thereby reducing the loss of the medicine.

[0050] Furthermore, the water retaining mechanism 340 includes a water retaining plate 341 and a telescopic sleeve 342. The swing shaft 324 passes through the water retaining plate 341 and is connected to the water retaining plate 341. The telescopic sleeve 342 is sleeved on the outside of the swing shaft 324. One end of the telescopic sleeve 342 is connected to the water retaining plate 341, and the other end is connected to the inner wall of the housing 10 and covers the perforation. The water retaining plate 341 and the telescopic sleeve 342 cover the perforation, so that the liquid medicine cannot flow out of the housing 10 through the perforation. At the same time, since the telescopic sleeve 342 can be elastically retracted, it does not affect the movement of the swing shaft 324, and the swing shaft 324 can still drive the connecting seat 310 to reciprocate along the axial direction of the conveying roller 110.

[0051] In this embodiment, the swing shaft 324 and the water baffle 341 can be connected as one piece, which is convenient for overall manufacturing and molding, and also strengthens the connection strength between the swing shaft 324 and the water baffle 341. At the same time, there is no gap between the swing shaft 324 and the water baffle 341 to prevent the medicine from entering the telescopic sleeve 342.

[0052] In some embodiments, Figure 4-7 As shown, the connection base 310 may include a base 3111 and a side plate 3112, and the base 3111 and the side plate 3112 may be enclosed to form a receiving cavity 315, and a portion of the receiving cavity 315 forms a liquid inlet channel 311. The connection base 310 of this embodiment adopts a split structure, which is convenient for arranging the liquid inlet channel 311, and can reduce the material used for the connection base 310, thereby reducing the manufacturing cost.

[0053] The connecting seat 310 can be provided with a through groove 313 that passes through the connecting seat 310 along the axial direction of the conveying roller 110, and a rotating hole 314 can be provided on the inner wall of the through groove 313. A support rod is passed through the rotating hole 314. The end of the swing shaft 324 can be provided with a through opening, and the support rod is passed through the opening and can rotate in the opening to realize the rotational connection between the connecting seat 310 and the swing shaft 324.

[0054] The rotating hole 314 can be connected to the accommodating chamber 315, and a drainage hole 316 connected to the accommodating chamber 315 can be set at the bottom of the connecting seat 310. When the medicine enters the accommodating chamber 315 along the support rod, the medicine can be discharged through the drainage hole 316 to avoid the medicine accumulating in the accommodating chamber 315.

[0055] In some embodiments, Figure 1 , Figure 2and Figure 8 As shown, the swing device 300 is located at one end of the upper spray pipe 210 and the lower spray pipe 220, which can prevent the swing device 300 from interfering with the conveying circuit board of the conveying device 100. The other ends of the upper spray pipe 210 and the lower spray pipe 220 are both provided with a bracket 260, and the upper spray pipe 210 and the lower spray pipe 220 are both placed on the bracket 260. When the swing device 300 drives the upper spray pipe 210 and the lower spray pipe 220 to reciprocate along the axial direction of the conveying roller 110, the ends of the upper spray pipe 210 and the lower spray pipe 220 close to the bracket 260 will move accordingly on the bracket 260, and the bracket 260 supports the upper spray pipe 210 and the lower spray pipe 220 to keep the upper spray pipe 210 and the lower spray pipe 220 stable, and at the same time, does not limit the upper spray pipe 210 and the lower spray pipe 220 to reciprocate along the axial direction of the conveying roller 110.

[0056] Furthermore, a limiting mechanism for limiting the movement of the upper spray pipe 210 and the lower spray pipe 220 along the conveying direction is also provided on the bracket 260 , so that the upper spray pipe 210 and the lower spray pipe 220 can keep moving along the axial direction of the conveying roller 110 .

[0057] Furthermore, the support 260 may include a support rod 261 and a limiting wheel 262 sleeved on the support rod 261, and the ends of the upper spray pipe 210 and the lower spray pipe 220 close to the support 260 are placed on the limiting wheel 262. The support rod 261 extends along the conveying direction, and the limiting mechanism is a limiting groove 263 provided on the circumference of the limiting wheel 262, and a part of the upper spray pipe 210 and the lower spray pipe 220 is embedded in the limiting groove 263, so as to limit the movement of the upper spray pipe 210 and the lower spray pipe 220 along the conveying direction.

[0058] In other embodiments, the ends of the upper spray pipe 210 and the lower spray pipe 220 close to the bracket 260 can be slidably connected with the bracket 260 along the axial direction of the conveying roller 110, which has a better guiding and limiting effect on the upper spray pipe 210 and the lower spray pipe 220. Furthermore, the bracket 260 can also be provided with a limiting mechanism for limiting the movement of the upper spray pipe 210 and the lower spray pipe 220 along the conveying direction, so that the upper spray pipe 210 and the lower spray pipe 220 can keep moving along the axial direction of the conveying roller 110.

[0059] In some embodiments, Figure 1-3 As shown, the conveying rollers 110 can be arranged in two groups, upper and lower, and the circuit board is arranged between the upper and lower groups of conveying rollers 110. The conveying rollers 110 located at the lower side support the circuit board from the bottom of the circuit board, and the conveying rollers 110 located at the upper side abut against the top surface of the circuit board, thereby limiting the circuit board from tilting up or jumping upward from the top, so that the circuit board can move stably along the conveying direction.

[0060] In some embodiments, Figure 1-3As shown, a conveying wheel may be sleeved on the conveying roller 110, and the conveying wheel rotates with the conveying roller 110. During the process of conveying the circuit board, the conveying wheel contacts the circuit board, thereby reducing the contact area with the circuit board, allowing more areas on the circuit board to contact the solution, thereby ensuring a chemical reaction between the circuit board and the solution.

[0061] It should be noted that Figure 2 and Figure 3 The triangular structure connected to the nozzle 230 is a schematic diagram of the liquid medicine 231 sprayed by the nozzle 230.

Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the present invention is provided only for illustration, and not for limiting the present invention as defined by the attached claims and their equivalents.
