Description

TECHNICAL FIELD

[0001] The utility model relates to LED production technical field, concretely relates to a kind of assembly machine of PCB board and spraying fixture. BACKGROUND

[0002] In current LED production process, the surface treatment of PCB board is a crucial link. In order to improve the performance of PCB board, such as waterproofness, corrosion resistance and oxidation resistance, etc., it is usually necessary to carry out corresponding spraying treatment on the surface of PCB board to form a protective film on the surface of PCB board. Before using the spraying equipment to spray the PCB board, the PCB board needs to be accurately assembled on the spraying fixture. As a bridge connecting the PCB board and the spraying equipment, the main function of the spraying fixture is to fix the PCB board to ensure that the PCB board can remain stable during spraying and will not be misaligned due to movement or overturning, thereby ensuring the accuracy and consistency of spraying.

[0003] Currently, although the spraying equipment has achieved high automation and intelligence, it can complete large-area, high-precision spraying operation in a short time, but most LED production enterprises still rely on manual operation in the step of assembling the PCB board on the spraying fixture.

[0004] Therefore, it is a technical problem to be solved in current LED production process to develop an assembly machine of PCB board and spraying fixture to replace manual assembly method. UTILITY MODEL CONTENTS

[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0042] The present application provides an assembly machine for PCB board and spraying jig, which is used to improve the assembly efficiency of the PCB board 100 and the spraying jig 200.

[0043] Referring to Figure 1 As shown in the figure, Figure 1 For the perspective view of the assembly machine for PCB board and spraying jig in the embodiment, the assembly machine for PCB board and spraying jig comprises a rack 1, a PCB board feeding device 2, a jig feeding device 3 and an assembly device 4.

[0044] The rack 1 is provided with a feeding station 11 and an assembly station 12.

[0045] The PCB board loading device 2 is installed on the frame 1 , and the PCB board loading device 2 is used to transport the PCB board 100 to the loading station 11 .

[0046] The jig loading device 3 is installed on the frame 1 , and the jig loading device 3 is used to transport the spray jig 200 to the assembly station 12 .

[0047] The assembly device 4 is installed on the frame 1 , and is used to grab the PCB board 100 on the loading station 11 and transfer it to the spraying fixture 200 of the assembly station 12 .

[0048] When the PCB board and spray jig assembly machine of the above technical solution is in use, first, the PCB board loading device 2 transports the PCB board 100 to the loading station 11, while the jig loading device 3 transports the spray jig 200 to the assembly station 12. Then, the assembly device 4 grabs the PCB board 100 on the loading station 11 and transfers it to the spray jig 200 at the assembly station 12, thereby completing the assembly of the PCB board 100 and the spray jig 200. It can be seen that the PCB board and spray jig assembly machine, through the cooperation of the PCB board loading device 2, the jig loading device 3, and the assembly device 4, can automatically assemble the PCB board 100 and the spray jig 200, replacing manual assembly and effectively improving the assembly efficiency of the PCB board 100 and the spray jig 200.

[0049] See Figure 4 As shown, Figure 4 It is a structural schematic diagram of the jig loading device, assembly device and assembly visual inspection device in the embodiment. The above-mentioned assembly device 4 can use an existing gripping mechanism 41 such as a clamp or vacuum suction cup and a manipulator 42. The manipulator 42 is arranged on the frame 1 by screwing or welding. The output end of the manipulator 42 is connected to the gripping mechanism 41 by screwing or welding. In this way, the gripping mechanism 41 can grip or release the PCB board 100, and the manipulator 42 can transfer the PCB board 100. The two can cooperate to realize the transfer of the PCB board 100 on the loading station 11 to the spray jig 200 of the assembly station 12.

[0050] See Figure 1As shown, the assembly machine of the PCB board and the spraying jig further comprises a visual positioning device 5. The visual positioning device 5 is installed on the rack 1 and located at one side of the assembly station 12. When the PCB board 100 and the spraying jig 200 are assembled, the assembly device 4 is used to grab the PCB board 100 on the feeding station 11 and transfer the PCB board 100 to the visual positioning device 5 and the assembly station 12 in sequence. The visual positioning device 5 is used to detect whether the assembly device 4 grabs the PCB board 100 and the position of the grabbed PCB board 100. As can be seen, after the visual positioning of the PCB board 100 by the visual positioning device 5, the PCB board 100 is assembled to the spraying jig 200. Compared with the way that the assembly device 4 directly assembles the PCB board 100 to the spraying jig 200, the above-mentioned way can effectively avoid the situation that the assembly device 4 misses the material, and can ensure that the assembly device 4 accurately assembles the PCB board 100 to the spraying jig 200, thereby effectively improving the assembly precision and assembly quality of the PCB board 100 and the spraying jig 200.

[0051] The above-mentioned visual positioning device 5 can use an existing CCD camera and can visually position the PCB board 100.

[0052] Referring to Figure 1 and Figure 3 As shown, in one embodiment of the PCB board feeding device 2, the PCB board feeding device 2 comprises a first conveying belt 21, a suction cup 22 and a turnover mechanism 23. The first conveying belt 21 is installed on the rack 1 and located at one side of the feeding station 11. The first conveying belt 21 is used to convey the PCB board 100 to the position opposite to the feeding station 11. The suction cup 22 is used to adsorb or release the PCB board 100. The turnover mechanism 23 is arranged on the rack 1 by screwing or welding, and the output end of the turnover mechanism 23 is connected to the suction cup 22 by screwing or welding. The turnover mechanism 23 is used to drive the suction cup 22 to turn over, so as to turn over the PCB board 100 on the first conveying belt 21 to the feeding station 11. In this way, when the PCB board 100 to be sprayed is fed, first, the first conveying belt 21 is used to convey the PCB board 100 to the position opposite to the feeding station 11. At this time, the original position of the suction cup 22 is located at the feeding station 11. Then, the turnover mechanism 23 drives the suction cup 22 to turn over towards the first conveying belt 21, so that the suction cup 22 contacts the PCB board 100 and adsorbs the PCB board 100. Finally, the turnover mechanism 23 drives the suction cup 22 to turn over towards the feeding station 11 and returns to the original position, so as to turn over the PCB board 100 to the feeding station 11 and make the back of the PCB board 100 face upwards, thereby facilitating the assembly device 4 to grab the PCB board 100 and assemble the PCB board 100 to the spraying jig 200.

[0053] The suction cup 22 can use an existing vacuum suction cup to adsorb and grab the PCB 100 by negative pressure, or the suction cup 22 can use other grabbing mechanisms such as a clamping jaw instead. The first conveying belt 21 can use an existing motor-belt driven conveying, or the first conveying belt 21 can use conveying chains or transplanting mechanisms instead. The turnover mechanism 23 can use an existing rotary motor or rotary cylinder as a rotary driving mechanism.

[0054] Referring to Figure 1 The first to-position detection member 211 is installed below the input end of the first conveying belt 21, and the second to-position detection member 212 is installed below the first conveying belt 21 and opposite the loading station 11. The first to-position detection member 211 is used to detect whether the PCB 100 is input to the first conveying belt 21, and the second to-position detection member 212 is used to detect whether the PCB 100 is conveyed to be opposite the loading station 11. In this way, when the PCB 100 is input to the first conveying belt 21, the first to-position detection member 211 can detect the PCB 100 at the input end of the first conveying belt 21. At this time, if the second to-position detection member 212 cannot detect the PCB 100, the first conveying belt 21 will convey the PCB 100 to be opposite the loading station 11. If the second to-position detection member 212 can detect the PCB 100, the first conveying belt 21 will stop conveying, so that the PCB 100 detected by the second to-position detection member 212 is limited to be opposite the loading station 11, so that the turnover mechanism 23 can transfer the PCB 100 opposite the loading station 11 to the loading station 11. It can be seen that the cooperation of the first to-position detection member 211 and the second to-position detection member 212 can facilitate accurate control of the position of the PCB 100 on the first conveying belt 21, thereby improving the assembly precision and quality of the PCB 100 and the spraying jig 200.

[0055] The first to-position detection member 211 and the second to-position detection member 212 can both use to-position sensors or infrared sensors.

[0056] Referring to Figure 1 and Figure 3As shown, on the basis of the above embodiment, the output end of the turnover mechanism 23 is provided with a third position detection member 231 and a fourth position detection member 232. The third position detection member 231 is located at one side of the suction cup 22 and is used to detect whether the suction cup 22 contacts the PCB board 100. The fourth position detection member 232 is used to detect the turnover position of the output end of the turnover mechanism 23 to determine whether the turnover mechanism 23 turns the suction cup 22 to the feeding station 11. In this way, when the first conveying belt 21 is used to convey the PCB board 100 to the position opposite to the feeding station 11, the second position detection member 212 detects the PCB board 100, the first conveying belt 21 stops conveying, and at the same time, the turnover mechanism 23 drives the suction cup 22 to turn towards the first conveying belt 21, so that the suction cup 22 contacts the PCB board 100 on the first conveying belt 21; then, the third position detection member 231 detects the PCB board 100, and the suction cup 22 adsorbs the PCB board 100; finally, the turnover mechanism 23 drives the suction cup 22 to turn towards the feeding station 11, so as to turn the PCB board 100 to the feeding station 11, at this time, the fourth position detection member 232 detects that the output end of the turnover mechanism 23 turns back to the original position. It can be seen that the cooperation of the first position detection member 211, the second position detection member 212, the third position detection member 231 and the fourth position detection member 232 can conveniently and accurately control the conveying of the PCB board 100 to the feeding station 11, so that the subsequent assembling device 4 can grasp the PCB board 100 on the feeding station 11, thereby improving the assembling precision and quality of the PCB board 100 and the spraying jig 200.

[0057] The third position detection member 231 can be a position sensor or an infrared sensor, and the fourth position detection member 232 can be a position sensor or a position switch.

[0058] Referring to Figure 1 and Figure 4As shown, in an embodiment of the jig loading device 3, the jig loading device 3 comprises a lifting frame 31, a lifting driving mechanism 32 and a second conveying belt 33. The lifting driving mechanism 32 is arranged on the rack 1 by screwing or welding and is in driving connection with the lifting frame 31. The lifting driving mechanism 32 is used to drive the lifting frame 31 to move up or down to move into or out of the assembly station 12. The second conveying belt 33 is installed on the lifting frame 31 and is used to convey the spray jig 200 to the position opposite to the assembly station 12 and output the spray jig 200 from the lifting frame 31. In this way, when the empty spray jig 200 is loaded, first, the spray jig 200 is input into the second conveying belt 33, and the second conveying belt 33 conveys the spray jig 200 to the position opposite to the assembly station 12. Then, the lifting driving mechanism 32 drives the lifting frame 31 to move up towards the assembly station 12 to move the spray jig 200 into the assembly station 12. After the PCB board 100 and the spray jig 200 are assembled, the lifting driving mechanism 32 drives the lifting frame 31 to move down to return to the original position or to move down to a set output height. Finally, the second conveying belt 33 is reversely conveyed to output the spray jig 200 and the PCB board 100 on the spray jig 200 from the assembly machine. If the lifting frame 31 is at the set output height, the lifting driving mechanism 32 drives the lifting frame 31 to return to the original position for the next time to load the empty spray jig 200. As can be seen, the assembly machine of the PCB board and the spray jig can not only automatically load the empty spray jig 200 through the jig loading device 3, but also automatically unload the spray jig 200 loaded with the PCB board 100, that is, the loading and unloading of the spray jig 200 share the same device and operation space, which greatly saves the equipment cost and operation space.

[0059] The lifting driving mechanism 32 described above can use a linear displacement driving mechanism such as a ball screw linear module or a linear motor linear module. The output end thereof is connected with the lifting frame 31 by screwing or welding. The second conveying belt 33 described above can use a motor-belt driving conveying or a conveying chain or a transplanting mechanism instead.

[0060] The first conveying belt 21 described above can be connected with the conveying mechanism of the previous process of the assembly machine, and the second conveying belt 33 can be connected with the conveying mechanism of the spray equipment. In this way, the first conveying belt 21 can directly input the PCB board 100 completed in the upstream into the assembly machine to be assembled with the spray jig 200. After the assembly, the second conveying belt 33 can output the spray jig 200 and the PCB board 100 on the spray jig 200 from the assembly machine to the spray equipment for spraying. In this way, the whole process is fully automated, which greatly improves the automation degree of the LED production line and improves the production efficiency of the LED product.

[0061] Referring to Figure 4As shown, on the basis of the above embodiment, a fifth position detection member 331 is installed below the input end of the second conveying belt 33, and a sixth position detection member 332 is also installed below the second conveying belt 33, and the sixth position detection member 332 is opposite to the position of the assembly station 12. The fifth position detection member 331 is used to detect whether the spraying jig 200 is input or output from the second conveying belt 33, and the sixth position detection member 332 is used to detect whether the spraying jig 200 is conveyed to be opposite to the position of the assembly station 12. In this way, when the spraying jig 200 is input to the second conveying belt 33, the fifth position detection member 331 can detect the spraying jig 200 at the input end of the second conveying belt 33, at this time, if the sixth position detection member 332 cannot detect the spraying jig 200, the second conveying belt 33 will convey the spraying jig 200 to be opposite to the position of the assembly station 12, if the sixth position detection member 332 detects the spraying jig 200, the second conveying belt 33 will stop conveying, so as to limit the spraying jig 200 detected by the sixth position detection member 332 to be opposite to the position of the assembly station 12, so that the subsequent lifting driving mechanism 32 can lift the spraying jig 200 opposite to the position of the assembly station 12 to the feeding station 11. It can be seen that the cooperation of the fifth position detection member 331 and the sixth position detection member 332 can conveniently and accurately control the position of the spraying jig 200 on the second conveying belt 33, so as to further improve the assembly precision and assembly quality of the PCB board 100 and the spraying jig 200.

[0062] The fifth position detection member 331 and the sixth position detection member 332 can both use a position sensor or an infrared sensor, etc.

[0063] Referring to Figure 2 and Figure 4As shown, on the basis of the above embodiment, the jig loading device 3 further comprises a top rod 6 and a top rod driving mechanism 7. The top rod 6 is slidably arranged on the lifting frame 31. The top rod driving mechanism 7 is arranged on the lifting frame 31 by screwing or welding, and is in driving connection with the top rod 6. The top rod driving mechanism 7 is used to drive the top rod 6 to move towards or away from the second conveying belt 33, so as to tightly abut or release the spraying jig 200 on the second conveying belt 33. In this way, since the second conveying belt 33 stops conveying when the spraying jig 200 is conveyed to the position opposite to the assembly station 12, although the spraying jig 200 can be limited at the position opposite to the assembly station 12, the spraying jig 200 may be bumped during the process of transferring the PCB board 100 to the spraying jig 200 by the assembly device 4, which causes the spraying jig 200 to move and offset, thereby affecting the assembly of the PCB board 100 and the spraying jig 200. Therefore, when the spraying jig 200 is conveyed to the position opposite to the assembly station 12 by the second conveying belt 33, the top rod driving mechanism 7 drives the top rod 6 to move towards the second conveying belt 33, so as to tightly abut the spraying jig 200 on the second conveying belt 33, thereby realizing the positioning of the spraying jig 200, effectively avoiding the movement of the spraying jig 200 during the assembly process, and further improving the assembly precision and quality of the PCB board 100 and the spraying jig 200. After the assembly of the PCB board 100 and the spraying jig 200, the top rod driving mechanism 7 drives the top rod 6 to move away from the second conveying belt 33, so as to release the spraying jig 200, so that the subsequent second conveying belt 33 can output the spraying jig 200 and the PCB board 100 thereon from the assembly machine.

[0064] The above-mentioned top rod driving mechanism 7 can use a linear displacement driving mechanism such as a telescopic air rod or a telescopic electric rod. The output end of the linear displacement driving mechanism is connected with the top rod 6 by welding or integral connection.

[0065] Referring to Figure 1 and Figure 4As shown, the assembling machine of the PCB board and the spraying jig further comprises an assembling visual detection device 8, which is installed on the rack 1 and located above the assembling station 12, and is used to detect the mounting position of the PCB board 100 on the spraying jig 200. In this way, after the PCB board 100 and the spraying jig 200 are assembled, whether the mounting position of the PCB board 100 on the spraying jig 200 is accurate and qualified can be detected by the assembling visual detection device 8. If the assembly is qualified, the lifting driving mechanism 32 and the second conveying belt 33 can cooperate with each other to output the spraying jig 200 and the PCB board 100 thereon from the assembling machine. Otherwise, the staff can be warned in time for processing, so as to prevent the un-assembled PCB board 100 and the spraying jig 200 from flowing into the next process, or the assembling visual detection device 8 can also visually position the PCB board 100, cooperate with the assembling device 4 to re-assemble the PCB board 100 and the spraying jig 200, and then the lifting driving mechanism 32 and the second conveying belt 33 cooperate to flow the PCB board 100 and the spraying jig 200 into the next process until the assembly is qualified.

[0066] The assembling visual detection device 8 described above can use an existing CCD camera, which can visually detect the mounting position of the PCB board 100 on the spraying jig 200, and also can visually position the PCB board 100.

[0067] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
