Description

Technical Field

[0001] The present invention relates to the field of printed circuit boards, and particularly to a circuit board exposure production line. Background Art

[0002] As is well known, in the production and manufacturing process of circuit boards, an exposure machine is required to expose the circuit boards. During the use of the exposure machine, the printed circuit board needs to be placed on the exposure plane of the exposure machine, and after the exposure is completed, the board needs to be taken out and turned over to expose the second side. However, the existing printed circuit board production line has a low degree of automation, and manual labor is required to transfer the board materials in the board frame into the production line. During transportation, the board surface is contacted over a large area, resulting in scratches on the board surface, differences in gloss, and affecting the overall quality of the board. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a circuit board exposure production line that can automatically perform loading, processing, and transportation of board parts.

[0004] According to a first aspect embodiment of the present invention, a circuit board exposure production line includes: a processing track, a loading unit, a transportation unit, an exposure unit, and a unloading unit; the loading unit includes a first material frame, and the loading unit can drive the first material frame to move close to the processing track, or the loading unit can drive the board materials in the first material frame to move close to the processing track; the transportation unit is arranged on the processing track, and the transportation unit can drive the board materials to move along the processing track; the transportation unit can place the board materials at the exposure unit, and the transportation unit can drive the board materials at the exposure unit to move along the processing track; the unloading unit includes a second material frame, the transportation unit can drive the board materials to the unloading unit, the unloading unit can drive the board materials to move into the second material frame, and the unloading unit can drive the second material frame to move away from the processing track.

[0005] According to the circuit board exposure production line of the embodiment of the present invention, it has at least the following beneficial effects: Before processing, an operator can place several board materials in the first material frame. The loading unit drives the first material frame to move close to the processing track so that the transportation unit on the processing track can pick up the board materials. Thus, the board materials are transported to the exposure unit for exposure processing.

If there is a description of first and second, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0039] In the description of the present invention, unless otherwise clearly defined, words such as setting, installing, connecting, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0040] Referring to Figure 1 , a circuit board exposure production line includes: a processing track 200, a loading unit 100, a transportation unit 600, an exposure unit 500, and an unloading unit 400; the loading unit 100 includes a first material frame 810, and the loading unit 100 can drive the first material frame 810 to move closer to the processing track 200, or the loading unit 100 can drive the sheet material in the first material frame 810 to move closer to the processing track 200; the transportation unit 600 is arranged on the processing track 200, and the transportation unit 600 can drive the sheet material to move along the processing track 200; the transportation unit 600 can place the sheet material at the exposure unit 500, and the transportation unit 600 can drive the sheet material at the exposure unit 500 to move along the processing track 200; the unloading unit 400 includes a second material frame 820, the transportation unit 600 can drive the sheet material to the unloading unit 400, the unloading unit 400 can drive the sheet material to move into the second material frame 820, and the unloading unit 400 can drive the second material frame 820 to move away from the processing track 200.

[0041] Before processing, the operator can place several sheet materials in the first material frame 810. The loading unit 100 drives the first material frame 810 to move closer to the processing track 200 so that the transportation unit 600 on the processing track 200 can pick up the sheet materials. Thus, the sheet materials are transported to the exposure unit 500 for exposure processing. After the exposure processing is completed, the transportation unit 600 drives the exposed sheet materials to the unloading unit 400 and stores them in the second material frame 820. When there is a sufficient amount of sheet materials stored in the second material frame 820, finally, the unloading unit 400 drives the material frame to move away from the processing track 200 to complete the unloading operation. By directly using the first material frame 810 to transport the sheet materials, the conversion process of transferring the sheet materials from the traditional sheet frame to the automatic line for temporary storage can be omitted, thus saving time and reducing the labor intensity of the operator. Since the sheet materials are transported by the loading unit 100, the transportation unit 600, and the unloading unit 400 during the processing, external factors such as the operator can be effectively prevented from contacting the surface of the sheet materials, thereby avoiding phenomena such as scratching on the sheet surface. Moreover, the fully automatic transportation and processing can also improve the processing efficiency and reduce the occurrence probability of sheet dropping and jamming.

[0042] In some embodiments, referring to Figure 2 , the loading unit 100 includes a material picking mechanism that can drive a single sheet material in the first material frame 810 to move closer to the processing track 200. The material picking mechanism can pick up parts in the first material frame 810, thereby moving a single sheet material onto the processing track 200 for subsequent processing. The material picking mechanism can drive the sheet materials to enter the processing track 200 in sequence for processing, making the processing process more efficient and orderly.

[0043] Furthermore, the loading unit 100 includes a feeding mechanism 130 and a material frame removing mechanism 120. The feeding mechanism 130 can drive the first material frame 810 to move closer to the material picking mechanism, and the material frame removing mechanism 120 can drive the empty first material frame 810 away.

[0044] Specifically, the feeding mechanism 130 includes a plurality of driving rollers, and the first material frame 810 is arranged on the plurality of driving rollers. When the plurality of driving rollers rotate, the first material frame 810 can be driven to move.

[0045] In some embodiments, referring to Figure 5, the blanking frame mechanism 120 includes a second base 121, on which a lifting seat 123 and an adjustment transmission belt 122 are provided. The lifting seat 123 is connected to the feeding mechanism 130, and the adjustment transmission belt 122 can adjust the relative distance between the two side baffles of the first frame 810, thereby adjusting the width of the first frame 810. The lifting seat 123 is connected to a lifting cylinder 124, which can drive the lifting seat 123 away from the second base 121, so as to facilitate the removal of the empty first frame 810.

[0046] In some embodiments, referring to Figure 3 , the blanking mechanism includes a pushing component 140 and a clamping component 150. The pushing component 140 and the clamping component 150 are respectively located on both sides of the first frame 810. The pushing component 140 can push the sheet material in the first frame 810 so that it moves out of the first frame 810, and the clamping component 150 can clamp the sheet material that has left the first frame 810 and drive it to move closer to the processing track 200. After the pushing component 140 pushes the sheet material out of the first frame 810, the clamping component 150 will clamp the sheet material that has left the first frame 810 and drive it closer to the processing track 200, so as to facilitate the transportation unit 600 to transport the sheet material. Through the cooperative action of the pushing component 140 and the clamping component 150, the sheet material can be moved from the first frame 810 to the processing track 200 alone, so that the processing operation can be carried out more efficiently and orderly.

[0047] In some embodiments, referring to Figure 4 , the pushing component 140 includes a first base 141, on which a first scissor component 143 is provided. The first base 141 and the first frame 810 are respectively located on both sides of the first scissor component 143, and the first scissor component 143 can push the sheet material in the first frame 810. Specifically, the first scissor component 143 is connected to a scissor driving mechanism 142. After the scissor driving mechanism 142 operates, it will push the two ends of the first scissor component 143 closer to each other. During the process of the two ends of the first scissor component 143 approaching each other, the middle part thereof will rise relatively, so as to push a single sheet material in the first frame 810, and thus achieve the effect of pushing the sheet material from the first frame 810 to the clamping component 150.

[0048] Specifically, the first scissor component 143 includes a plurality of connecting bars, the ends of the plurality of connecting bars are sequentially hinged, and the plurality of connecting bars are arranged in a crisscross manner. Among the plurality of connecting bars, at least one connecting bar has one end not hinged to other connecting bars. The scissor driving mechanism 142 is hinged to this end, and the other end of this connecting bar is hinged to the first base 141.

[0049] Specifically, the scissor drive mechanism 142 includes a scissor drive cylinder. The piston rod of the scissor drive cylinder is hinged to the end of the connecting bar. Of course, the scissor drive mechanism 142 can also be composed of other components, and the specific implementation can be adjusted accordingly according to the actual situation, which is not limited herein.

[0050] In some embodiments, referring to Figure 1 , a dust removal device 900 is provided above the feeding mechanism 130. When the first scissor assembly 143 drives the sheet material to move, it will pass through the dust removal device 900. The dust removal device 900 can remove dust and sundries on the sheet material, thereby avoiding the influence of the sundries attached to the sheet material on the processing of the sheet material.

[0051] Specifically, the dust removal device 900 includes an ion bar.

[0052] Specifically, dust removal devices 900 are provided on both sides of the feeding mechanism 130. The two dust removal devices 900 can remove dust from both sides of the sheet material, thereby effectively reducing the external influence on the sheet material during processing.

[0053] In some embodiments, referring to Figure 6 , the clamping assembly 150 includes a first bracket 110. First clamping plates 155 are provided on both sides of the first bracket 110, and one or both of the two first clamping plates 155 are movably arranged on the first bracket 110; a clamping drive mechanism 151 is provided on the first bracket 110, and the clamping drive mechanism 151 can drive the two first clamping plates 155 to approach or move away from each other. After the clamping drive mechanism 151 is started, the two first clamping plates 155 will approach relatively, so that the two first clamping plates 155 clamp a single sheet material relatively. Through the combined action of the clamping drive mechanism 151 and the first clamping plates 155, the sheet material can be effectively clamped and fixed, facilitating the picking unit to pick up the part.

[0054] Specifically, the clamping drive mechanism 151 includes a clamping drive motor, the clamping drive motor is connected with a clamping transmission belt, one of the two first clamping plates 155 is arranged on the clamping transmission belt and is movably connected to the first bracket 110 through a first guide rail pair 153, and the other is fixed on the first bracket 110. Of course, the clamping drive mechanism 151 can also be composed of other components, and the specific implementation can be adjusted accordingly according to the actual situation, which is not limited herein.

[0055] In some embodiments, referring to Figure 6 , a first jaw cylinder 156 is provided on the first clamping plate 155. The first jaw cylinder 156 can further clamp and fix the sheet material between the two first clamping plates 155, thereby preventing the sheet material from falling off between the two first clamping plates 155, and further preventing problems such as the sheet material falling off or being scratched due to sliding during processing.

[0056] In some embodiments, referring to Figure 1 , there are two exposure units 500, and a turning mechanism 300 is arranged between the two exposure units 500. When the circuit board is exposed, both sides of the sheet material need to be exposed. Usually, during the exposure process, after the exposure is completed, the operator needs to manually take out the sheet material and turn it over to expose the second side. This undoubtedly has problems such as high labor intensity, repetitive work, and low efficiency of the operator. The turning mechanism 300 can automatically turn over the sheet material, thereby improving the operation efficiency and reducing the manual burden.

[0057] In some embodiments, referring to Figure 1 , Figure 7 and Figure 8 , the turning mechanism 300 includes a second support 310 arranged between the two exposure units 500. A clamping assembly is arranged on the second support 310, and the clamping assembly can vertically clamp the sheet material; the transportation unit 600 includes a plurality of mounting seats 610 movably arranged on the processing track 200. A jaw seat 640 is rotatably arranged on the mounting seat 610, and a jaw 650 is arranged on the jaw seat 640; the transportation unit 600 is arranged on both sides of the clamping assembly, and the jaw seats 640 located on both sides of the clamping assembly can rotate and press closely against the clamping assembly. After the first exposure of the sheet material is completed, the jaw seat 640 will pick up the first side of the sheet material through the jaw 650 and drive the sheet material to rotate to the clamping assembly for clamping. Subsequently, the jaw seat 640 on the other side of the second support 310 will rotate close to the second support 310 and pick up the second side of the sheet material, thereby driving the sheet material to move to another exposure unit 500. Since the two jaw seats 640 respectively pick up the opposite sides of the sheet material, when the two jaw seats 640 place the sheet material on the exposure unit 500, the orientation of the sheet material will be opposite, thus simply and directly achieving the turning effect. At the same time, in the existing mechanism, the sheet material is usually adsorbed and transported by a suction cup. However, the adsorption and transportation by the suction cup have the problem of insufficient firmness. The jaw 650 can firmly clamp the sheet material, thereby making the transportation process more stable.

[0058] In some embodiments, referring to Figure 9, the clamping assembly includes second clamping plates 350 arranged on both sides of the second bracket 310, and one or both of the two second clamping plates 350 are movably arranged on the second bracket 310; a clamping driving mechanism 390 is arranged on the second bracket 310, and the clamping driving mechanism 390 can drive the two second clamping plates 350 to approach or separate from each other. After the clamping driving mechanism 390 is activated, the two second clamping plates 350 will approach relatively, so that the two second clamping plates 350 clamp a single sheet material relatively. Through the combined action of the clamping driving mechanism 390 and the second clamping plates 350, the sheet material can be effectively clamped and fixed, so as to facilitate the gripper seat 640 to suck the sheet material.

[0059] Specifically, a transport motor 620 is arranged on the mounting seat 610, and a first gear-rack pair 630 is arranged between the mounting seat 610 and the processing track 200. The transport motor 620 drives the mounting seat 610 to move along the processing track 200 through the first gear-rack pair 630.

[0060] Specifically, a connecting seat 660 is arranged between the mounting seat 610 and the gripper seat 640. The connecting seat 660 is connected to the mounting seat 610 in a liftable manner through a third guide rail pair 670 and a second gear-rack pair 680. The gripper seat 640 is rotatably arranged on the connecting seat 660, and a steering driving motor 665 connected to the gripper seat 640 and capable of driving the gripper seat 640 to rotate is arranged on the connecting seat 660.

[0061] Specifically, the clamping driving mechanism 390 includes a clamping driving motor. The clamping driving motor is connected to the clamping driving mechanism 390. One of the two second clamping plates 350 is arranged on the clamping driving mechanism 390 and is movably connected to the second bracket 310 through a second guide rail pair 330, and the other is fixed on the second bracket 310. Of course, the clamping driving mechanism 390 can also be composed of other components, and the specific implementation manner can be adjusted according to the actual situation, which is not limited here.

[0062] Specifically, a second gripper cylinder 360 is arranged on the second clamping plate 350. The second gripper cylinder 360 can further clamp and fix the sheet material between the two second clamping plates 350, so as to prevent the sheet material from falling off between the two second clamping plates 350, and further prevent problems such as the sheet material falling off or being scratched due to sliding during the processing.

[0063] In some embodiments, refer to Figure 10, the blanking unit 400 includes a third support 410. A material clamping mechanism 450 is provided at the upper part of the third support 410. The transportation unit 600 can transport the sheet material to the material clamping mechanism 450. A lifting mechanism 440 and a plurality of discharging mechanisms 430 are provided at the lower part of the third support 410. There are multiple second material frames 820, which are arranged on the discharging mechanisms 430 in a one-to-one correspondence. The lifting mechanism 440 can drive the sheet material on the material clamping mechanism 450 to descend into one of the multiple second material frames 820. The multiple second material frames 820 can classify and store the sheet material according to the situation of the sheet material, making the blanking process of the sheet material more orderly and clear. The material clamping mechanism 450 can, according to the operation of the operator or under the control of the detection component and the electric control component, transport the sheet material into the corresponding second material frame 820 according to its processing situation, so that the sheet material can be automatically classified and stored, thereby improving the processing efficiency and quality.

[0064] Specifically, the lifting assembly includes a third base and a second scissor assembly. One end of the second scissor assembly is hinged to the third base, and the other end is connected to the scissor lifting mechanism 440. The scissor lifting mechanism 440 can drive the two ends of the second scissor assembly to approach or move away from each other. The third base and the second material frame 820 are respectively located on both sides of the second scissor assembly. After the scissor lifting mechanism 440 operates, it will push the two ends of the second scissor assembly to approach each other. During the process of the two ends of the second scissor assembly approaching each other, the middle part thereof will rise relatively, thereby pushing a single sheet material in the second material frame 820, and thus achieving the effect of pushing the sheet material from the second material frame 820 to the clamping assembly 150.

[0065] Specifically, the material clamping mechanism 450 includes third clamping plates arranged on both sides of the third support 410. One or both of the two third clamping plates are movably arranged on the third support 410. A material clamping driving mechanism is provided on the third support 410. The material clamping driving mechanism can drive the two first clamping plates 155 to approach or move away from each other. After the material clamping driving mechanism is started, the two third clamping plates will approach each other relatively, so that the two third clamping plates clamp a single sheet material relatively. Through the combined action of the material clamping driving mechanism and the third clamping plates, the sheet material can be effectively clamped and fixed, which is convenient for the gripper seat 640 to suck the sheet material.

[0066] Specifically, the material clamping driving mechanism includes a material clamping driving motor. The material clamping driving motor is connected with a material clamping transmission belt. One of the two third clamping plates is arranged on the material clamping transmission belt and is movably connected to the third support 410 through a third guide rail pair 670, and the other is fixed on the third support 410. Of course, the material clamping driving mechanism can also be composed of other components, and the specific implementation method can be adjusted according to the actual situation and is not limited here.

[0067] Specifically, a third jaw cylinder is provided on the third clamping plate. The third jaw cylinder can further clamp and fix the sheet material between the two third clamping plates, thereby preventing the sheet material from falling off between the two third clamping plates, and further preventing problems such as the sheet material falling off or being scratched due to sliding during the processing.

[0068] In some embodiments, referring to Figure 10 , a feeding frame mechanism 420 is provided on the third support 410, and the second material frame 820 is arranged on the feeding frame mechanism 420.
