[0017] In order to make the object, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not to limit the present application.

[0018] The present application provides a line board pressing needle and rubbing plate device.

[0019] Referring to Figures 1 to 7 , including line board 1, operation platform 11, sliding seat 12, first mold base 13, X-axis conveying module 14, receiving plate 15, Y-axis conveying module 16, second mold base 17, positioning plate 21, pressing cover plate 22, sliding seat 12 is fixedly connected on operation platform 11, first mold base 13 is connected on sliding seat 12 through sliding, first mold base 13 has a notch with the same shape as line board 1, which is used for embedding line board 1 in the notch, in addition, first mold base 13 has two long slot notches, which are used for better placing line board 1 by user, the long slot notches can also be used for limiting the bottom of pin needle, which is used for positioning line board 1.

[0020] The X-axis conveying module 14 is arranged in the long side direction of the slide 12, and the X-axis conveying module 14 comprises a receiving plate 15, and the pressing plate module is connected to the receiving plate 15, and the receiving plate 15 moves along with the linear motor on the X-axis conveying module 14, so as to compensate the sliding stroke of the pressing plate module, press the pins on the circuit board 1 on the first mold base 13, and move the circuit board 1, so that the circuit board 1 is automatically transferred after being pressed. The pressing plate module comprises a positioning plate 21 and a pressing cover plate 22 which slide relative to each other, the positioning plate 21 is fixedly connected to the receiving plate 15, and the pressing cover plate 22 is raised and lowered based on the positioning plate 21. Through the relative movement of the two, the circuit board 1 on the first mold base 13 is extruded, so that the pin on the circuit board 1 is fixed on the circuit board 1.

[0021] The Y-axis conveying module 16 is the same as the X-axis conveying module 14, and is driven by a linear motor, so as to control the movement of the wiping plate module. The Y-axis conveying module 16 is arranged in the wide side direction of the slide 12, and the wiping plate module is connected to the Y-axis conveying module 16, so as to automatically wipe the surface of the circuit board 1 after being pressed. The second mold base 17 is fixedly connected to the operation platform 11, and the second mold base 17 is arranged on one side of the wiping plate module. The second mold base 17 is used for placing the circuit board 1 after being pressed, so as to prevent the circuit board 1 from sliding randomly. Preferably, a plurality of long slot openings are formed on the surface of the second mold base 17. Through the slot openings, the pin tail on the back of the circuit board 1 can be clamped in the slot openings, so that when the wiping plate module wipes the circuit board 1, the circuit board 1 can remain stable and slide relative to the wiping plate module, thereby ensuring the wiping effect of the wiping plate module.

[0022] The wiping plate module not only significantly improves the automation level of the production line, but also optimizes the production process comprehensively. By ensuring efficient cooperation between each link, the wiping plate module can achieve precise control and fast operation, thereby improving production efficiency and effectively ensuring safety during the production process. The design of the X-axis conveying module 14 further expands the sliding stroke of the wiping plate module, enabling it to flexibly handle line boards 1 of different lengths, providing higher flexibility and adaptability. Not only does it improve the overall applicability of the production line, but it also ensures efficient operation of the equipment under various product specifications. At the same time, the cooperation between the wiping plate module and the Y-axis conveying module 16 enables the surface of the line board 1 to be precisely and automatically wiped. This automated process avoids the uncertainty of manual operation, improving the production efficiency and surface quality of the line board 1, ensuring the reliability and stability of the product. Each operation step is completed by program control, completely eliminating errors that may be caused by human factors, ensuring the smooth operation of the pressing needle and wiping plate. This high degree of automation and precise control not only ensures the improvement of production efficiency, but also positively affects the subsequent line board welding process. By ensuring standardization and high-precision execution of each processing link, the stability of line board welding quality is improved. This means that every link in the entire production process is finely controlled, providing more reliable protection for the quality of the final product, ensuring efficient and stable production line operation.

[0023] Referring to Figures 1 to 3 , the unloading module 18 is arranged on the operation platform 11 and is used for automatically unloading the wiped line board 1. The unloading module 18 comprises a conveying table 41, an unloading bin 42 and a lifting table 43. The conveying table 41 is arranged along the conveying direction of the sliding seat 12. The unloading bin 42 is slidably connected to the conveying table 41. The lifting table 43 is fixedly connected to the Y-axis conveying module 16. The lifting table 43 is connected to a lifting plate 44. The second suction disc 45 is fixedly connected to the lower side of the lifting plate 44. The addition of the unloading module 18 enables the processed line board 1 to be stably collected and transferred without returning through the X-axis conveying module 14 and the pressing plate assembly, so that the subsequent line board 1 can be quickly fed, thereby improving the production efficiency of the production line.

[0024] Referring to Figures 1 to 3 , the storage plate 46 is slidably connected to the unloading bin 42. The dial 461 is abutted to the lower side of the storage plate 46. The dial 461 is rotatably connected to the unloading bin 42. The outer wall of the unloading bin 42 is fixedly connected to the motor 47. The driving shaft of the motor 47 is coaxially fixedly connected to the dial 461. In order to improve the transportation cost of the finished product circuit board 1, that is, to reduce the moving frequency of the discharge bin 42, so that the discharge bin 42 can collect more circuit boards 1 in the same period of time, at this time, either enlarge the volume of the discharge bin 42, or increase the depth of the discharge bin 42, and the circuit board 1 is a product that needs to be carefully protected, so when it is transported into the discharge bin 42 by the discharge module 18, it needs to be adjusted according to the storage depth of the discharge bin 42, so that the circuit board 1 can be stably placed in the discharge bin 42, which increases the working pressure of the discharge module 18, so that the placing plate 46 on which the circuit board 1 is placed can be stably lifted according to the production line processing efficiency by rotating the dial 461 driven by the motor 47, thereby reducing the working pressure of the discharge module 18 and improving the production efficiency of the production line.

[0025] Referring to Figures 1 to 3 , the discharge plate 48 is elastically connected to the placing plate 46, and a spring with damping is arranged between the placing plate 46 and the discharge plate 48, so that the two are elastically connected, and then a weight detection module is added, and the weight detection module is arranged between the placing plate 46 and the discharge plate 48, for real-time detection of the weight of the material; The weight detection module arranged between the placing plate 46 and the discharge plate 48 detects the circuit board 1 placed on the discharge plate 48 in real time, and then adjusts the relative position of the placing plate 46 in the discharge bin 42 according to the weight, so that the user can adjust the efficiency of other processes without affecting the lifting speed and lifting frequency of the placing plate 46, thereby improving the automation of the entire production line.

[0026] Referring to Figures 4 to 7 On the basis of the above, the pressing plate module further comprises a first air cylinder 23, a first suction cup 24 and a second air cylinder 25, the first air cylinder 23 is fixedly connected to the receiving plate 15, the telescopic shaft of the first air cylinder 23 is slidingly connected with the pressing cover plate 22, the relative sliding of the pressing cover plate 22 and the positioning plate 21 is controlled by the first air cylinder 23, and the sliding distance is accurately controlled, so that the circuit board 1 with different pressing needle requirements can be pressed. The first suction cup 24 is elastically arranged on the pressing cover plate 22, and when the pressing cover plate 22 is pressed and reset upward, the first suction cup 24 adsorbs the circuit board 1 on the first mold base 13, the second air cylinder 25 is fixedly connected to the positioning plate 21, the telescopic shaft of the second air cylinder 25 is fixedly connected with the telescopic column 26, the telescopic column 26 enables the pressing cover plate 22 and the positioning plate 21 to stably operate when they slide relative to each other, and the other end of the telescopic column 26 is fixedly connected with the first suction cup 24; The pressing plate template is driven by the first cylinder 23 to drive the pressing plate 22 to slide up and down under the reference of the positioning plate 21. When the circuit board 1 arranged on the first mold base 13 moves to the lower side of the pressing plate 22, the pressing force applied by the pressing plate 22 can ensure that the pins on the circuit board 1 are fixed to the circuit board 1, thereby completing the pin pressing operation. Subsequently, the first cylinder 23 drives the pressing plate 22 to move upwards, and the elastically arranged first suction cup 24 protrudes from the lower side of the pressing plate 22 to quickly adsorb the circuit board 1, thereby completing the grasping of the circuit board 1 after the pin pressing. Then, with the driving of the second cylinder 25, the suction cup moves the circuit board 1, which has completed the pin pressing operation, to the direction of the second mold base 17, and finally stably arranges the circuit board 1 on the second mold base 17. In this process, the first suction cup 24 stops adsorbing, and the circuit board 1 stably falls into the second mold base 17 by gravity, thereby realizing accurate positioning and smooth transfer. Through the cooperation of the pin pressing operation of the pressing plate module and the suction cup transfer, the pressing plate module not only can automatically perform the pin pressing operation of the circuit board 1, but also can automatically grasp and transfer the circuit board 1 after the operation is completed, thereby greatly improving the processing efficiency. This automatic process reduces the need for manual intervention and improves the work efficiency of the production line. It is worth mentioning that between the sliding seat 12 and the second mold base 17, a transportation line perpendicular to the long side of the sliding seat 12 is designed. This transportation line is used to move the circuit board 1 processed by the pressing plate module to another station through the conveying system, and further into other pressing plate modules for processing. It is worth mentioning that the pressing plate modules on these stations are controlled by a Y-axis conveying module 16, which ensures accurate conveying and cooperation. In this way, the X-axis conveying module 14 can be used with multiple pressing plate modules, greatly improving the flexibility and expandability of the production line, reducing production costs, and further improving the production efficiency of the production line. Overall, the pressing plate module not only improves the automation level of the production line, but also optimizes the production process, ensures efficient cooperation at each link, realizes accurate control and rapid operation, and thus improves the production efficiency and ensures the production safety.

[0027] With reference to Figures 4 to 5 The pressing plate module includes a limiting block 31 fixedly connected with the Y-axis conveying module 16, the limiting block 31 is in sliding connection with a positioning block 32, a plurality of brush discs 33 are fixedly connected to the lower side of the positioning block 32, the brush disc 33 is in a cylindrical shape, and a plurality of soft fiber bristles are arranged thereon. When the brush disc 33 is used for scrubbing the surface of the circuit board 1, the soft fiber bristles can remove the waste and will not cause abrasion to the surface of the circuit board 1. In addition, the brush disc 33 can be rotatably arranged on the lower side of the positioning block 32, so that the brush disc 33 is in a rotating state during the scrubbing process. When the bristles on the brush disc 33 are entangled with the surface of the circuit board 1, the rotation of the brush disc 33 can buffer and guide the pulling force, thereby reducing the direct force of the bristles on the surface of the circuit board 1. The limiting block 31 is fixedly connected with a third cylinder 34, and the telescopic shaft of the third cylinder 34 is fixedly connected with the positioning block 32. The several brush plates 33 in the cleaning plate module reciprocate along with the Y-axis conveying module 16, and then under the accurate control of the third cylinder 34, the distance between the brush plate 33 and the upper surface of the circuit board 1 is kept at a set value, and thus the pressure of the brush plate 33 on the circuit board 1 is accurately controlled, which not only ensures that the brush plate 33 can automatically clean the surface of the circuit board 1 after the pressing plate, improves the automation of the production line, improves the production efficiency of the product, and reduces the labor intensity of the workers.

[0028] Referring to Figures 1 to 3 Both the clamping plates 51 are slidably connected to the upper side of the sliding seat 12, the limiting plate 52 is fixedly connected between the two clamping plates 51, and is used for limiting the distance between the two clamping plates 51, the clamping groove 53 is arranged on the clamping plate 51, the transmission plate 54 driven by the cylinder is slidably connected to the lower side of the sliding seat 12, the bending part on the lower side of the transmission plate 54 abuts against the inner wall of each clamping groove 53, and the two side edges of the transmission plate 54 are bent upward, and the transmission plate 54 is embedded in the clamping plate 51 through the bending part, so that the movement of the transmission plate 54 drives the movement of the clamping plate 51. Here, only one preferred measure for the movement of the transmission plate 54 is described, and other measures, such as the cooperation of a motor and a lead screw, or a cylinder drive, can also accurately control the movement of the transmission plate 54.

[0029] Compared with driving the pressing plate assembly to press and cover and adsorb the circuit board 1 on the first mold base 13 at a fixed position through the X-axis conveying module 14, the transmission plate 54 driven by the cylinder is used to drive the clamping plate 51 to move through the abutting relationship between the bending part and the inner wall of the clamping groove 53, so that the first mold base 13 clamped between the two clamping plates 51 moves, and the pressing action of the pressing plate assembly on the circuit board 1 moves away from the feeding position, so that the worker can normally observe the circuit board 1, and the worker is prevented from being injured by the pressing plate assembly due to accidental touch or other bad behaviors, and the safety of the worker is ensured.
