Description

Technical Field

[0001] This utility model belongs to the technical field, and specifically relates to a solder resist printing machine. Background Technology

[0002] Solder resist ink, often green in color, is commonly known as green ink. During PCB manufacturing, green ink needs to be printed on both the front and back of the PCB. While existing solder resist printing machines can meet the basic requirement of printing green ink on both sides of the PCB, and the conveyor structure can accommodate back-side printing through suspension support, the PCB is placed directly on the conveyor structure. After printing the front side, back-side printing requires flipping and adjusting the PCB. This involves removing the PCB from the conveyor structure, flipping it, and repositioning it. After printing both sides, the PCB must be removed from the conveyor structure again. These flipping and unloading processes are easily affected by the ink, causing significant inconvenience and failing to fully meet user needs. Utility Model Content

[0003] In view of this, this utility model addresses the shortcomings of the prior art by providing a solder resist printing machine that not only meets the basic requirement of printing ink on the front and back of PCB boards separately, but also allows workers to easily flip and unload the PCB boards after ink printing without being constrained by the installation structure, thereby more fully meeting people's usage needs.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a solder resist printing machine, including a frame, a processing table on the frame, a support on the processing table, a printing mechanism on the support, and a conveying module on the processing table. The conveying module includes a placement groove that slides back and forth on the processing table, and a mounting frame is engaged in the placement groove. Both the upper and lower ends of the mounting frame can be engaged with the placement groove. A support ring plate is provided on the inner side wall of the mounting frame for supporting the periphery of the PCB board. A locking bolt is provided on the middle side of the mounting frame, which can abut against the side of the PCB board to fix the connection between the PCB board and the mounting frame. The locking bolt is a hand-tightening bolt, which can be easily tightened and adjusted by hand by the worker. After the PCB board is placed into the mounting frame and supported by the support ring plate, the locking bolt can be tightened to flexibly fix the PCB board and the mounting frame together.

[0005] As a further improvement of this utility model, a linear slide is provided on the top left side of the processing table along the front-back direction, and a support groove is provided on the top right side of the processing table along the front-back direction. A first connecting plate connected to the slide block of the linear slide is provided on the left side of the placement groove, and a support slider slidably connected to the support groove is provided on the right side of the placement groove via a second connecting plate. The vertical cross-section of both the support groove and the support slider is T-shaped. Through the cooperation of the linear slide, the support groove, the first connecting plate, the second connecting plate, and the support slider, the placement groove can be slidably driven in the front-back direction.

[0006] As a further improvement of this utility model, the first connecting plate is provided with a first connecting slot for connecting to the slide of the linear slide table. The first connecting slot is provided with a first connecting bolt for screwing the slide of the linear slide table, and the slide of the linear slide table has a first threaded connection hole for screwing to the first connecting bolt. Through the cooperation of the first connecting slot, the first connecting bolt, and the first threaded connection hole, the first connecting plate and the slide of the linear slide table can be easily and flexibly fixed.

[0007] As a further improvement of this utility model, the second connecting plate is provided with a second connecting slot that engages and fixes with the upper end of the support slider. The second connecting slot is provided with a second connecting bolt for screwing the support slider, and the support slider is provided with a second threaded connection hole for screwing with the second connecting bolt. Through the cooperation of the second connecting slot, the second connecting bolt, and the second threaded connection hole, the second connecting plate and the support slider can be easily and flexibly fixed.

[0008] As a further improvement of this utility model, a handle is also provided at the middle side end of the mounting frame. The mounting frame can be moved by the handle; because the handle is located at the middle side end of the mounting frame, it will not be interfered with by the placement slot, and the mounting frame can be moved conveniently before and after flipping.

[0009] As a further improvement of this utility model, an anti-slip sleeve is also provided on the handle. The anti-slip sleeve makes it easier to operate the handle.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, the placement slot allows the mounting frame and PCB board to switch between the loading / unloading position and the processing position. After the front side is painted, the mounting frame and PCB board can be flipped and adjusted together. After the front and back sides are painted, the mounting frame and PCB board can be unloaded together. Therefore, it can effectively avoid the influence of the printed green ink on the flipping and unloading operations.

[0012] Secondly, the frame allows for convenient placement and subsequent processing of the unloaded PCB board, effectively preventing the green solder mask from being scratched or smeared. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 1 , 2As shown in Figure 3, a solder resist printing machine includes a frame 101, a processing table 102 mounted on the frame 101, a support 103 mounted on the processing table 102, a printing mechanism 104 mounted on the support 103, and a conveying module 200 mounted on the processing table 102. The conveying module 200 includes a placement groove 201 that slides back and forth on the processing table 102. A mounting frame 202 is engaged in the placement groove 201. Both the upper and lower ends of the mounting frame 202 can be engaged with the placement groove 201. A support ring plate 203 is provided on the inner side wall of the mounting frame 202 for supporting the periphery of a PCB board 209. A locking bolt 204 is provided at the middle side end of the mounting frame, which can abut against the side end of the PCB board 209 to fix the connection between the PCB board 209 and the mounting frame 202. The locking bolt 204 is a hand-tightening bolt, which can be easily tightened and adjusted by hand by the worker. After placing the PCB board 209 into the mounting frame 202 and supporting it with the support ring plate 203, tighten the locking bolts 204 to flexibly fix the PCB board 209 to the mounting frame 202.

[0022] Place the PCB board 209 into the mounting frame 202, and use the support ring plate 203 to support the periphery and back of the PCB board 209. Tighten the locking bolt 204 so that the inner end of the locking bolt 204 abuts against the side end of the PCB board 209, and fix the PCB board 209 in the mounting frame 202 to ensure that it will not shift during the printing process and will not tilt or fall off during the flipping and adjustment process.

[0023] Start the linear slide 205 and drive the slide block of the linear slide 205 to move from front to back. With the sliding cooperation between the support slider 208 and the support groove 206, drive the placement groove 201, the mounting frame 202 and the PCB board 209 from the loading and unloading station on the front side to the painting station on the rear side. Then, use the printing structure to print green oil on the front side of the PCB board 209.

[0024] After the front printing is completed, the drive placement slot 201, mounting frame 202 and PCB board 209 are moved from the painting station on the rear side to the loading and unloading station on the front side through the linear slide 205, support slide 206 and support slider 208. Then the mounting frame 202 and PCB board 209 are taken out from the placement slot 201 together and flipped over as a whole, with the back of the flipped PCB board 209 facing up. Then the flipped mounting frame 202 is re-clamped into the placement slot 201, ready for back printing. Because the PCB board 209 is fixed together with the mounting frame 202, the flipping process will not affect the already printed green solder mask on the front side.

[0025] Subsequently, the placement slot 201, mounting frame 202, and PCB board 209 are moved back to the painting work position, and the printing mechanism 104 is driven to print green ink on the back of the PCB board 209. After printing, the placement slot 201 is moved from the processing position to the unloading position through the cooperation of the linear slide 205, the support slide 206, and the support slider 208. The mounting frame 202 and PCB board 209 are then removed from the placement slot 201 for unloading.

[0026] The mounting frame 202 facilitates the placement and subsequent processing of the unloaded PCB board 209, effectively preventing the solder mask from being scratched or damaged. Using the mounting frame 202 for temporary placement or transport of the unloaded PCB board 209 further reduces the risk of solder mask damage.

[0027] According to another embodiment of the present invention, such as Figure 2 , 3 As shown, a linear slide 205 is provided on the top left side of the processing table 102 along the front-back direction, and a support slide 206 is provided on the top right side of the processing table 102 along the front-back direction. A first connecting plate 207 connected to the slide block of the linear slide 205 is provided on the left side of the placement slot 201, and a support slider 208 slidably connected to the support slide 206 is provided on the right side of the placement slot 201 via a second connecting plate 210. The vertical cross-section of both the support slide 206 and the support slider 208 is T-shaped. Through the cooperation of the linear slide 205, the support slide 206, the first connecting plate 207, the second connecting plate 210, and the support slider 208, the placement slot 201 can be slidably driven in the front-back direction.

[0028] According to another embodiment of the present invention, such as Figure 4 As shown, the first connecting plate 207 is provided with a first connecting slot 301 for connecting to the slide of the linear slide 205. The first connecting slot 301 is provided with a first connecting bolt 302 for screwing the slide of the linear slide 205. The slide of the linear slide 205 is provided with a first threaded connection hole for screwing the first connecting bolt 302. By simply engaging the slide of the linear slide 205 with the first connecting slot 301 and then passing the first connecting bolt 302 through the side wall of the first connecting slot 301 and screwing it into the first threaded connection hole, the slide of the linear slide 205 can be flexibly fixed to the first connecting plate 207 and the placement slot 201.

[0029] According to another embodiment of the present invention, such as Figure 3 , 4As shown, the second connecting plate 210 is provided with a second connecting slot 303 that engages and fixes with the upper end of the support slider 208. The second connecting slot 303 is provided with a second connecting bolt 304 for screwing the support slider 208. The support slider 208 has a second threaded connection hole for screwing the second connecting bolt 304. By simply engaging the support slider 208 with the second connecting slot 303 and then passing the second connecting bolt 304 through the side wall of the second connecting slot 303 and screwing it into the second threaded connection hole, the second connecting plate 210 and the support slider 208 can be flexibly fixed.

[0030] According to another embodiment of the present invention, such as Figure 3 , 5 As shown, a handle 305 is also provided at the middle side end of the mounting frame 202. The handle 305 is U-shaped. The mounting frame 202 can be moved by the handle 305. Because the handle 305 is located at the middle side end of the mounting frame 202, it will not be interfered with by the placement slot 201, and the mounting frame 202 can be moved conveniently before and after flipping.

[0031] According to another embodiment of the present invention, a non-slip sleeve (not shown in the figure) is also provided on the handle 305. The non-slip sleeve makes it easy to operate the handle 305.

[0032] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
