DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1, as Figure 1 As shown, an automatic loading and unloading device for circuit board printing includes a conveying seat 1, and positioning components 2 are symmetrically arranged on the left and right sides of the conveying seat 1, which can accurately adjust the circuit board to the middle position of the conveying seat 1 during the loading process to ensure that the circuit board does not deviate from the original track during the processing and avoid processing errors. A cleaning component 3 is arranged on the upper end of the conveying seat 1, and the cleaning component 3 can remove impurities brought by dust or dirt that may exist on the surface of the circuit board to avoid affecting the subsequent printing quality and the adhesion of the components. A printing component 4 is arranged on the front side of the cleaning component 3, and pushing components 5 are symmetrically arranged on the left and right ends of the front side of the conveying seat 1, which can intermittently and quickly push the circuit board from the front end of the conveying seat 1 to the next step to ensure that the circuit board enters the specified position. A lifting component 6 is arranged on the front side of the pushing component 5, which can automatically adjust the height according to the arrival of the circuit board to avoid manual intervention and ensure that each circuit board can accurately reach the specified position. A plurality of material trays 7 are arranged on the upper end of the conveying seat 1, and the circuit board is placed on the surface of the material tray 7.

[0034] Therefore, this solution uses the coordination of the conveying seat 1, the positioning component 2, the cleaning component 3 and the printing component 4 to accurately calibrate the position of the circuit board during the loading process, avoiding processing errors caused by inaccurate positioning, and simultaneously cleaning it to ensure the cleanliness of the circuit board surface, providing a good foundation for subsequent printing. Then, by utilizing the coordination between the conveying seat 1, the pushing component 5 and the lifting component 6, the printed circuit boards can be intermittently sent to the designated location for storage during the unloading process, which is convenient for quick storage and retrieval later, avoiding manual intervention while optimizing the entire loading and unloading process, ensuring the efficient and stable operation of the production line.

[0035] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve the effect of synchronously calibrating and cleaning the circuit board during the loading process.

[0036] See also Figure 1-5 A motor 11 is fixedly installed on the left side of the conveying base 1, and a transmission shaft 12 is fixedly connected to the output end of the motor 11. A transmission shaft 12 is rotatably connected to the end of the conveying base 1 away from the transmission shaft 12. The outer surface of the transmission shaft 12 is rotatably connected to the inner surface of the conveying base 1. A rotating shaft 13 is fixedly connected to the lower end of the conveying base 1, and the inner surface of the rotating shaft 13 is rotatably connected to a fixed base 14.

[0037] Specifically, the starting motor 11 drives the transmission shaft 12 and the transmission shaft 2 15 to rotate. When the transmission shaft 12 and the transmission shaft 2 15 rotate, the conveyor belt in the conveying seat 1 can be driven through the winding connection to slowly transport several material trays 7 from the rear end to the front end, so as to stably load and unload the circuit board.

[0038] See also Figure 2 and Figure 3 The positioning assembly 2 includes a transmission mechanism 21 fixedly connected to the transmission shaft 12, and the side of the transmission mechanism 21 away from the transmission shaft 12 is fixedly connected to the fixed seat 14. The upper side of the right end of the rotating shaft 13 is rotatably connected to the rotating shaft 25, and the outer surface of the rotating shaft 25 and the outer surface of the fixed seat 14 are jointly fixedly connected with a bevel gear transmission group 24.

[0039] Furthermore, the transmission mechanism 21 is composed of two pulleys and a belt, and the diameter of the pulley fixedly connected to the transmission shaft 12 is larger than the diameter of the pulley fixedly connected to the fixed seat 14, and the diameter ratio is three to one. The bevel gear transmission group 24 is composed of two mutually meshing bevel gears, which can change the rotation direction so that when the fixed seat 14 rotates, the rotating shaft 25 rotates with it.

[0040] Furthermore, when the conveying seat 1 drives the material tray 7 to be transported forward, the transmission shaft 12 will drive the transmission mechanism 1 21 to rotate, thereby driving the fixed seat 14 and the bevel gear transmission group 24 to rotate, so that the rotating shaft 2 25 rotates.

[0041] See also Figure 3 The upper end of the rotating shaft 25 is fixedly connected to a rotating seat 26, one side of the upper end of the rotating seat 26 is fixedly connected to a protrusion 27, the outer surface of the protrusion 27 is slidably connected to a limiting ring 28, the left side of the limiting ring 28 is fixedly connected to a telescopic rod 29, the end of the telescopic rod 29 away from the limiting ring 28 is fixedly connected to the conveying seat 1, the upper end of the limiting ring 28 is fixedly connected to a fixing frame 210, the left end of the fixing frame 210 is fixedly connected to a connecting rod 211, and the left end of the connecting rod 211 is fixedly connected to a clamping block 212.

[0042] Furthermore, the telescopic rod 29 can limit the limit ring 28. When the rotating seat 26 and the protrusion 27 rotate, the limit ring 28 can only slide left and right and will not rotate with the protrusion 27, thereby driving the fixed frame 210, the connecting rod 211 and the clamping block 212 to move back and forth left and right, calibrating the position of the material tray 7 on the surface of the conveying seat 1, ensuring that the circuit board is located in the middle position and does not deviate from the original track during the processing, thereby avoiding processing errors.

[0043] Furthermore, when the rotating shaft 25 rotates, it will drive the rotating seat 26 and the protrusion 27 to rotate together, so that the limit ring 28 continuously moves left and right under the rotation of the protrusion 27, driving the fixed frame 210, the connecting rod 211 and the clamping block 212 to calibrate the position of the moving material tray 7, so that it remains in the middle position of the conveying seat 1.

[0044] See also Figure 4 The cleaning assembly 3 includes four support columns 31 fixedly connected to the upper end of the conveying base 1, the upper ends of the support columns 31 are commonly fixedly connected to a fixed block 32, the upper end of the fixed frame 210 is fixedly connected to a rack 33, the outer surface of the rack 33 is slidably connected to the fixed block 32, the outer surface of the rack 33 is meshingly connected to a gear 34, the inner surface of the gear 34 is fixedly connected to a rotating shaft 35, the outer surface of the rotating shaft 35 is rotatably connected to the fixed block 32, and the lower end of the rotating shaft 35 is fixedly connected to a cleaning brush 36.

[0045] Furthermore, during the conveying process of the conveying base 1, the rack 33 moves left and right along with the fixed frame 210. The meshing of the rack 33 and the gear 34 can drive the gear 34 and the rotating shaft 35 to continuously perform reciprocating rotational motion, so that the circuit board inside the material tray 7 being calibrated can be cleaned and the circuit board can be kept clean to ensure that the quality of subsequent processes is not affected by impurities or dust.

[0046] See also Figure 5The printing assembly 4 includes a second fixing seat 41 fixedly connected to the upper end of the conveying seat 1 , a hydraulic device 42 is fixedly installed at the lower end of the second fixing seat 41 , and a printing device 43 is fixedly installed at the lower end of the hydraulic device 42 .

[0047] Furthermore, the printing device 43 belongs to transfer printing in the prior art, which is only briefly described in this solution. Its main working principle is as follows:

[0048] The pre-treated circuit board is placed under the printing device 43, and the circuit board is aligned with the pattern on the transfer film. Then the printing device 43 applies a certain pressure and temperature to the circuit board through a specific pressure device and a heating device, so that the pattern on the transfer film can be firmly adhered to the circuit board. Under the action of the applied pressure and temperature, the pattern on the transfer film will gradually transfer to the circuit board. In this process, the ink or metal layer on the transfer film will chemically react or physically adhere to the surface of the circuit board to form the desired circuit pattern. After the pattern transfer is completed, the transfer film is peeled off from the circuit board to complete the printing.

[0049] Furthermore, when the conveyor base 1 drives the material tray 7 to slowly move to the designated printing position, the conveyor base 1 needs to stop moving, start the hydraulic device 42 and the printing device 43, and print the circuit board. After the processing is completed, the conveyor base 1 continues to operate.

[0050] Therefore, this solution can synchronously calibrate and clean the position of the circuit board during the loading process through the cooperation between the conveying seat 1 and the positioning component 2, the cleaning component 3, and the printing component 4, ensuring that the circuit board is always in the predetermined position during transportation, reducing manual operation, avoiding processing errors, and using the cleaning brush 36 to quickly remove surface debris before formal printing, ensuring that the circuit board is not affected by impurities or dust and affecting the quality of subsequent processes, thereby improving work efficiency.

[0051] Embodiment 3: Based on Embodiments 1 and 2, this embodiment is to achieve the effect of storing processed circuit boards intermittently one by one.

[0052] See also Figure 1 , Figure 6-10 The pushing assembly 5 includes an intermittent transmission group 1 52 fixedly connected to the right end of the transmission shaft 2 15. The intermittent transmission group 1 52 is composed of two bevel gears with different radii. The inner surface of the intermittent transmission group 1 52 is fixedly connected to a rotating shaft 4 53, and the lower end of the rotating shaft 4 53 is rotatably connected to a base 16.

[0053] The upper end of the rotating shaft 4 53 is fixedly connected to the transmission mechanism 2 55, and the end of the transmission mechanism 2 55 away from the rotating shaft 4 53 is fixedly connected to the rotating shaft 5 56. The lower end of the rotating shaft 5 56 is rotatably connected to the conveying seat 1, and the outer surface of the rotating shaft 5 56 is fixedly connected to the toggle block 57.

[0054] Specifically, the two bevel gears in the intermittent transmission group 1 52 have different rotation speeds. When the two are meshed, the bevel gear fixedly connected to the rotating shaft 4 53 rotates faster, and only half of the bevel gear tooth surface is fixedly connected to the transmission shaft 2 15, and the other half is a smooth surface. Its main function is to allow the rotating shaft 4 53 to rotate intermittently. The transmission mechanism 2 55 is composed of two pulleys and a belt, which can drive the toggle block 57 to rotate together with the rotating shaft 4 53.

[0055] Furthermore, when the printing of the material tray 7 is completed, they will move one by one to the front of the conveying base 1. During the rotation process, the transmission shaft 2 15 will drive the intermittent transmission group 1 52 and the rotating shaft 4 53 to rotate intermittently, and the rotation speed of the rotating shaft 4 53 is faster than that of the transmission shaft 2 15. When the intermittent transmission group 1 52 itself is engaged, the rotating shaft 4 53 will drive the transmission mechanism 2 55, the rotating shaft 56 and the toggle block 57 to rotate rapidly, thereby causing the toggle block 57 to rotate clockwise, quickly toggling the material tray 7 at the front end, so that the material tray 7 moves forward a distance.

[0056] See also Figure 6-10 The lifting assembly 6 includes a transmission mechanism three 61 fixedly connected to the left and right ends of the transmission shaft two 15, the ends of the two transmission mechanisms three 61 away from the transmission shaft two 15 are fixedly connected to the rotating shaft six 62, the sides of the two rotating shafts six 62 away from each other are rotatably connected to the support block 63, the ends of the two rotating shafts six 62 away from the support block 63 are fixedly connected to the intermittent transmission group two 64, and the inner surfaces of the two intermittent transmission groups two 64 are fixedly connected to the bidirectional lead screw 65.

[0057] See also Fig. 9 and Fig.10 The lower ends of the two bidirectional lead screws 65 are rotatably connected to a base 66, and the outer surfaces of the two bidirectional lead screws 65 are threadedly connected to a lifting seat 67. A storage box 68 is provided at the upper end of the lifting seat 67, and a plurality of partition plates 69 are fixedly connected to the interior of the storage box 68.

[0058] Furthermore, the transmission mechanism 3 61 is composed of two pulleys and a belt, so that the rotating shaft 62 and the transmission shaft 2 15 rotate synchronously, and the intermittent transmission group 2 64 is composed of two mutually meshing bevel gears, and only half of the bevel gear tooth surface is fixedly connected to the rotating shaft 62, and the other half is a smooth surface. Its main function is to allow the bidirectional lead screw 65 to rotate intermittently, and the bidirectional lead screw 65 can drive the lifting seat 67 to move up and down when rotating. The storage box 68 and the partition plate 69 can store the circuit board, which protects the integrity of the circuit board and is also convenient for quick storage and retrieval later;

[0059] By setting the threaded groove on the surface of the bidirectional lead screw 65, the distance between the two material trays 7 is equal to the distance of one grid of the partition plate 69. Then, when one material tray 7 enters the partition plate 69, when the material tray 7 on the surface of the next conveying seat 1 moves forward, the storage box 68 will rise or fall one grid, so that the next material tray 7 can smoothly enter the next grid of the partition plate 69. The storage box 68 and the partition plate 69 can stay in the correct position without tilting or misalignment, and the partition plate 69 is tilted toward the inside of the storage box 68, so that the material tray 7 can slide in quickly.

[0060] When the material tray 7 is moved forward for a while, the two bevel gears in the intermittent transmission group 1 52 are in meshing state, and the two bevel gears in the intermittent transmission group 2 64 are in a non-meshing state, so the storage box 68 is in a stagnant state, and the material tray 7 can slide smoothly into the partition plate 69 without getting stuck. When the conveying seat 1 conveys the next material tray 7 forward again, the intermittent transmission group 1 52 is not meshed yet and the toggle block 57 has not yet toggled the material tray 7, the transmission shaft 2 15 will drive the rotating shaft 6 62 to rotate, so that the intermittent transmission group 2 64 is meshed with each other, thereby driving the two-way lead screw 65 to rotate, so that the lifting seat 67 drives the storage box 68 to drop the distance of the partition plate 69 as a whole, so that the next material tray 7 can enter smoothly, and then the storage of the material tray 7 is repeated in this way. When the lifting seat 67 drives the storage box 68 to drop until the partition plate 69 is full, the storage box 68 can be taken away and a new storage box 68 can be put on, and then the previous process is repeated, but at this time the lifting seat 67 drives the storage box 68 to be in an ascending state;

[0061] The material trays 7 to be transported on the conveying seat 1 are just enough to fill two storage boxes 68. After the two storage boxes 68 are full, the printing work comes to an end. There are no material trays 7 to be transported on the surface of the conveying seat 1. At this time, the conveying seat 1 is controlled to operate so that the lifting seat 67 returns to the bottom;

[0062] When a new job starts, the first material tray 7 is placed at the very beginning of the conveying seat 1. After passing through the positioning component 2, the cleaning component 3, the printing component 4 and the pushing component 5, when it reaches the front end of the conveying seat 1, the storage box 68 just rises from the top to the highest point and is in a descending state. The first material tray 7 can now smoothly enter the lowest partition plate 69, and then the subsequent work is circulated.

[0063] Therefore, in this solution, through the structural coordination between the conveying seat 1, the printing component 4 and the pushing component 5, during the material unloading process, the toggle block 57 can intermittently toggle the material tray 7 at the front end of the conveying seat 1, and quickly send the material tray 7 to the storage box 68, and then use the intermittent transmission group 2 64 to make the bidirectional screw 65 intermittently rotate, ensuring that the storage box 68 and the partition plate 69 stay in the correct position to allow the circuit board to enter smoothly without tilting or misalignment, thereby maximizing the use of storage space, avoiding the scattered stacking of circuit boards and occupying too much space, and facilitating quick access in the later stage, and also ensuring the smoothness of the overall material unloading.

[0064] It should be noted that the specific installation method of the conveying base 1, the motor 11 and the printing device 43 used in the present invention, the circuit connection method and the control method are all conventional designs and will not be elaborated in detail in the present invention.

[0065] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
