Description

Technical Field

[0001] The present invention relates to the technical field of circuit board processing structures, and in particular to a circuit board water jet assembly and a circuit board processing device. Background Art

[0002] In the process of processing circuit boards, multiple processes such as browning and developing are involved. In many processes, the circuit boards are treated by spraying liquid medicine. For example, in the processes such as browning and developing, liquid medicine or deionized water is sprayed on the circuit boards by a water jet structure to meet the requirements of different processes. In actual use, the water jet structure needs to be cleaned regularly to avoid uneven liquid discharge. In this regard, technicians in this field have proposed many improvement schemes for the water jet structure in the field of circuit board processing.

[0003] Taking the "CN217283645U-A special water jet for browning of circuit boards" in the prior art as an example, the improvement scheme it adopts is "providing a filtering device can prevent impurities from clogging the water outlet channel, causing uneven water outlet and affecting the browning effect". For a water jet equipped with a flow channel structure, providing a filtering device can largely solve the problem of impurities in the liquid medicine clogging the flow channel structure. However, for the development process, the sprayed liquid medicine is an alkaline solution (such as sodium carbonate, sodium hydroxide, etc.). During the spraying process, it is easy to precipitate precipitation in the flow channel, which eventually leads to blockage of the flow channel structure, and then leads to poor subsequent processing effects of the circuit board. Since the cause of the blockage is not the impurities in the liquid medicine, but the components of the liquid medicine itself, precipitation will still be precipitated in the flow channel after the filtering device is used, and it is still necessary to regularly dismantle and replace the water jet structure and perform maintenance.

[0004] It can be seen that when the water jet structure in the prior art faces the situation of being blocked by the liquid medicine itself, it is still necessary to dismantle and replace the water jet structure for maintenance, which has the technical problem of low maintenance efficiency.

[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] Embodiment 1:

[0046] The circuit board water jet assembly provided in this embodiment is suitable for the processing scene of the circuit board, and is used to evenly spray or spray liquids such as liquid medicine, cleaning liquid, etc. on the circuit board. For example, it can be used in the development process to spray liquid medicine for development on the circuit board, and can also be used for cleaning liquid medicine in the browning process, or liquid in other processes. This embodiment takes the development process as an example to introduce the circuit board water jet assembly. In this embodiment, by improving the structure of the circuit board water jet assembly, the function of replacing the internal flow channel is realized, thereby reducing the frequency of overall disassembly and replacement of the circuit board water jet assembly, and the overall structure of the circuit board water jet assembly helps the staff to perform overall maintenance, and has the advantage of high maintenance efficiency.

[0047] like Figure 1 and Figure 2 As shown, the circuit board water jet assembly in this embodiment includes a water jet housing 100, one end of the water jet housing 100 is provided with a liquid inlet channel 101, and the other end of the water jet housing 100 is slidably connected with a liquid outlet assembly 200. The liquid inlet channel 101 is used for the entry of liquid medicine, and after the liquid medicine enters the water jet housing 100, it is discharged through the liquid outlet assembly 200. The liquid outlet assembly 200 is slidably connected to the water jet housing 100, which means that the liquid outlet assembly 200 can be independently and quickly replaced, thereby improving maintenance efficiency.

[0048] like Figures 2 to 4 , Figure 7As shown, the liquid outlet component 200 includes a liquid outlet plate 210 that can slide along a first direction, and the liquid outlet plate 210 is provided with a plurality of groups of first main channels 211 and second main channels 212 that are arranged in pairs, and the first main channels 211 and the second main channels 212 are alternately arranged along the first direction; a blocking plate 220 is installed on one side of the liquid outlet plate 210, and the blocking plate 220 is correspondingly provided with piston portions 221 of the same number as the first main channels 211, and the piston portions 221 can move between a first position extending into the main channel and a second position away from the main channel; when the piston portion 221 is located at the first position, the liquid outlet plate 210 is fixed relative to the water knife housing 100; when the piston portion 221 is located at the second position, the liquid outlet plate 210 can slide along the first direction to adjust the position of the above-mentioned main channel. By adjusting the position of the liquid outlet plate 210 , one of the first main channel 211 and the second main channel 212 can be connected to the liquid inlet channel 101 and discharge the liquid medicine, and the other of the first main channel 211 and the second main channel 212 is penetrated by the piston part 221 .

[0049] like Figures 2 to 4 , Figure 6 As shown, the liquid outlet assembly 200 further includes a driving portion 230 for driving the blocking plate 220 to move between the first position and the second position, and the driving portion 230 at least partially extends outside the water jet housing 100. By setting the driving portion 230, the position of the blocking plate 220 can be changed, thereby facilitating the subsequent change of the position of the liquid outlet plate 210.

[0050] Specifically, in the circuit board water jet assembly of the present embodiment, when working, one of the first main channel 211 and the second main channel 212 is extended by the piston part 221, and the other of the first main channel 211 and the second main channel 212 plays the role of liquid discharge, which means that the liquid can enter the water jet housing 100 through the liquid inlet channel 101 and be discharged through the liquid outlet assembly 200; after working for a period of time, the piston part 221 is driven by the driving part 230 to move to the second position, at which time the liquid outlet plate 210 can slide, and by sliding the position of the liquid outlet plate 210, the other of the first main channel 211 and the second main channel 212 is moved to below the piston part 221, and one of the first main channel 211 and the second main channel 212 is moved to below the piston part 221. The first main channel 211 and the second main channel 212 are no longer aligned with the piston part 221, and then the piston part 221 is driven to move to the first position by the driving part 230, the liquid outlet plate 210 is fixed, and the other of the first main channel 211 and the second main channel 212 is extended by the piston part 221, the internal sediment is pushed down, and one of the first main channel 211 and the second main channel 212 is used as a discharge port to discharge the liquid; thus, in the long-term working process, different main channels can be replaced as discharge ports through the reciprocating motion of the liquid outlet plate 210, and the piston part 221 plays the role of partially extending into and conducting the main channel, which can extend the effective working time of the circuit board water jet assembly, reduce the frequency of disassembly and replacement of the circuit board water jet assembly, and thus improve maintenance efficiency.

[0051] As a preferred implementation in this embodiment, along the first direction, a first spacing is left between adjacent first main channels 211 and second main channels 212, and a second spacing is left between adjacent two piston parts 221, and the second spacing is twice the first spacing. This arrangement means that the first main channel 211 and the second main channel 212 can be replaced by moving the liquid outlet plate 210 by the first spacing. As another optional implementation, the main channels are spaced at equal intervals, and the piston parts 221 are spaced at equal intervals, so that at least part of the main channel is extended into by the piston part 221, and at least another part of the main channel serves to discharge the liquid medicine.

[0052] Furthermore, if Figure 4 and Figure 6As shown, the driving part 230 includes a movable plate 231 penetrating the water jet housing 100 along the first direction, and the movable plate 231 is slidably connected to the water jet housing 100 along the first direction; a lifting part 232 is provided on the movable plate 231, and a triggering part 222 is correspondingly provided on one side of the lifting part 232 of the blocking plate 220; when the blocking plate 220 is located at the first position, the triggering part 222 is not in contact with the top surface of the lifting part 232, and when the blocking plate 220 is located at the second position, the triggering part 222 is in contact with the top surface of the lifting part 232. It can be understood that by providing the uneven movable plate 231, when the movable plate 231 is moved along the first direction, the lifting part 232 and the triggering part 222 can lift the blocking plate 220, thereby lifting the blocking plate 220 from the first position to the second position.

[0053] That is to say, in this embodiment, the position of the blocking plate 220 can be changed by changing the position of the movable plate 231 outside the water jet housing 100, which has the advantage of convenient operation. In addition, in this embodiment, the movable plate 231 is driven to move by manual pulling. In other optional embodiments, it can also be pushed and pulled by a linear motor or other forms.

[0054] In this embodiment, the movable plate 231 is provided with a first receiving groove 233 and a second receiving groove 234 arranged in pairs, the first receiving groove 233 and the second receiving groove 234 are arranged at intervals, and the movable plate 231 forms a lifting portion 232 between the first receiving groove 233 and the second receiving groove 234; when the blocking plate 220 is located at the first position, the trigger portion 222 is at least partially embedded in the first receiving groove 233 or the second receiving groove 234; wherein, a trigger portion 222 is provided at both ends of the blocking plate 220, and two pairs of first receiving grooves 233 and second receiving grooves 234 are correspondingly provided on the movable plate 231. Through this arrangement, the blocking plate 220 is lifted at both ends, which can effectively improve the stability of the blocking plate 220 when the position is changed.

[0055] In this embodiment, if Figure 4 , Figures 6 to 8 As shown, a sliding groove 213 is provided on one side of the liquid outlet plate 210 facing the movable plate 231, and the movable plate 231 is slidably connected to the sliding groove 213; along the first direction, the length of the liquid outlet plate 210 is less than the width of the inner cavity 102 of the water jet housing 100, and a movable groove 214 is provided on at least one side edge of the sliding groove 213, and a flange portion 235 is convexly provided on the movable plate 231 corresponding to the movable groove 214, and the flange portion 235 at least partially extends into the movable groove 214; wherein, the length of the flange portion 235 is less than the length of the movable groove 214, and first elastic members (not shown) are respectively provided between the flange portion 235 and the groove walls on both sides of the movable groove 214, and one end of the first elastic member abuts against the movable groove 214, and the other end of the first elastic member abuts against the flange portion 235. The first elastic member may be a compression spring.

[0056] Exemplarily, when the staff periodically changes the position of the main channel, they pull / pull the movable plate 231, and the movable plate 231 overcomes the elastic force of the first elastic member and slides along the sliding groove 213. At this time, the liquid outlet plate 210 does not move, but the lifting portion 232 of the movable plate 231 moves correspondingly to the bottom of the trigger portion 222 (that is, the trigger portion 222 leaves the first receiving groove 233), thereby lifting the blocking plate 220; then, in the process of the lifting portion 232 passing through the trigger portion 222, under the force transmission of the first elastic member, the movable plate 231 moves synchronously with the liquid outlet plate 210, thereby changing the position of the main channel; finally, the end of the liquid outlet plate 210 is supported by the inner cavity 102 of the water jet housing 100, and the movable plate 231 continues to move. The movable plate 231 further overcomes the elastic force of the first elastic member and continues to slide along the sliding groove 213. At this time, the liquid outlet plate 210 does not move, so that the lifting portion 232 is separated from the trigger portion 222 (that is, the trigger portion 222 enters the second receiving groove 234). That is to say, the trigger portion 222 is arranged in an isosceles trapezoid. Through the above arrangement, when the lifting portion 232 moves along the inclined surface of the trigger portion 222, the liquid outlet plate 210 does not move during the up and down movement of the sealing plate 220. When the lifting portion 232 moves along the end surface of the trigger portion 222, the sealing plate 220 maintains in the second position, and the liquid outlet plate 210 can move under the elastic force of the first elastic member, thereby ensuring that the piston portion 221 can smoothly enter the main channel, effectively avoiding the breakage of the piston portion 221, thereby improving the overall life.

[0057] As a supplementary embodiment, the liquid outlet component 200 includes a liquid outlet shell 240 fixedly connected to the inner cavity 102 of the water knife shell 100, the liquid outlet shell 240 is configured with a liquid outlet cavity 241 arranged along the first direction, the liquid outlet plate 210 and the sealing plate 220 are slidably connected in the liquid outlet cavity 241, and the driving part 230 passes through the liquid outlet cavity 241; the cavity wall of the liquid outlet cavity 241 is provided with a slag discharge groove 242 corresponding to each piston part 221, and the cavity wall of the liquid outlet cavity 241 is provided with a liquid outlet hole 243 on one side of the slag discharge groove 242; one of the first main channel 211 and the second main channel 212 is provided corresponding to the slag discharge groove 242, and the other of the first main channel 211 and the second main channel 212 is provided corresponding to the liquid outlet hole 243. In addition, in order to ensure the sealing of the inner cavity 102, a sealing gasket 110 and a mounting plate 120 may be installed at the ends of the water jet housing 100 respectively, and the sealing gasket 110 may be pressed onto the water jet housing 100 by the mounting plate 120 to ensure the sealing.

[0058] Furthermore, a limiting part 300 is embedded in the liquid outlet cavity 241, and the limiting part 300 is provided with a limiting cavity 301, and the blocking plate 220 is slidably installed in the limiting cavity 301 along the second direction; the limiting cavity 301 is provided with a piston hole 302 corresponding to each piston part 221; a second elastic member (not shown in the figure, a compression spring can be selected) is installed in the limiting cavity 301, one end of the second elastic member abuts against the cavity wall of the limiting cavity 301, and the other end of the second elastic member abuts against the blocking plate 220, so that the blocking plate 220 has a tendency to move along the first position. Through the setting of the limiting part 300 and the second elastic member, it can be ensured that the piston part 221 enters the active channel, which plays a role in assisting slag discharge.

[0059] In this embodiment, if Figure 4 and Figure 5 As shown, the limiting part 300 includes a lower limiting plate 310 and an upper limiting plate 320 which are sequentially stacked on the liquid outlet plate 210, and the widths of the lower limiting plate 310 and the upper limiting plate 320 are both smaller than the width of the liquid outlet plate 210; wherein, the liquid outlet cavity 241 includes an upper fixed cavity 2411 and a lower sliding cavity 2412 which are connected, and the width of the upper fixed cavity 2411 is smaller than the width of the lower sliding cavity 2412; the lower limiting plate 310 and the upper limiting plate 320 are embedded in the upper fixed cavity 2411, and the liquid outlet plate 210 is slidably connected to the lower sliding cavity 2412. The limiting part 300 is embedded in the upper fixed cavity 2411, and since the size of the upper fixed cavity 2411 is small, it is helpful to fix and install the limiting part 300.

[0060] Furthermore, positioning plates 250 are respectively installed at the two ends of the movable plate 231 extending outside the liquid outlet shell 240, and the positioning plates 250 are detachably connected to the side wall portion of the liquid outlet shell 240 through fasteners; when one of the positioning plates 250 is connected to the side wall portion, the first main channel 211 connects the liquid inlet channel 101 and the liquid outlet hole 243, and the second main channel 212 is extended by the piston portion 221 and connected to the slag discharge groove 242; when the other positioning plate 250 is connected to the side wall portion, the first main channel 211 is extended by the piston portion 221 and connected to the slag discharge groove 242, and the second main channel 212 connects the liquid inlet channel 101 and the liquid outlet hole 243. In addition, the water jet housing 100 is provided with a slag discharge hole 103, which is convenient for the staff to insert the discharge rod into the slag discharge groove 242 through the slag discharge hole 103. At this time, the discharge rod can pass through the slag discharge groove 242 through the slag discharge hole 103 on one side and discharge the sediment from the slag discharge hole 103 on the other side, thereby realizing slag removal without disassembly, which can effectively improve efficiency.
