[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1-4 As shown, this utility model provides a fully automatic printing machine, which includes a first workbench 1, a second workbench 2, and a third workbench 3, which are independently set. The first workbench 1 and the third workbench 3 are detachably connected to the second workbench 2. The first workbench 1 is equipped with a feeding system 101, the second workbench 2 is equipped with a printing system 201, and the third workbench 3 is equipped with a detection system 301. The detection system 301 includes a machine compartment 302, a CDD vision inspection module 303 located in the machine compartment 302, and two curing devices 304 for curing solder paste on the surface of the circuit board. The inner wall of the machine compartment 302 is also equipped with an electric slide rail 305 connecting the curing devices 304.
[0027] This embodiment consists of three detachable worktables: one for loading, one for printing, and one for inspection. Its main feature is its modular design, allowing for flexible combinations to meet different needs. The detailed design of each worktable also aims to improve accuracy, efficiency, and adaptability.
[0028] During operation, the circuit boards are placed sequentially in their corresponding positions by the feeding system 101. The feeding system 101 is equipped with sensors that automatically detect the length and width of the circuit boards. Based on the detected data, it automatically adjusts the dimensions of the circuit boards using corresponding adjustment mechanisms, making it suitable for circuit boards of different sizes. The circuit boards then pass through the printing system 201 and the inspection system 301 to complete their respective operations. The device on the printing system 201 used to hold the circuit boards is also adjustable. After the solder paste is evenly applied to the surface of the circuit boards by the printing system 201, the circuit boards proceed to the next process. The circuit boards undergo quality inspection by the CDD vision inspection module 303 of the inspection system 301. The CDD vision inspection module 303 is connected to an alarm module installed on the display terminal. When defective products are detected, an alarm signal is sent to the display terminal, allowing operators to detect them promptly and further improving product quality and reliability. After inspection, the circuit boards undergo accelerated curing of the solder paste on their surface by two curing units 304, saving time and improving work efficiency.
[0029] The feeding system 101 includes a first conveyor 102 and a second conveyor 103 that are independently set up. A channel for conveying circuit boards is formed between the first conveyor 102 and the second conveyor 103. A spacing adjustment mechanism is provided between the first conveyor 102 and the second conveyor 103. The first conveyor 102 moves along the direction of the second conveyor 103 through the spacing adjustment mechanism.
[0030] In this embodiment, the first conveyor 102 can move along the direction of the second conveyor 103 via a spacing adjustment mechanism, thereby adjusting the channel width between the two conveyors. The spacing adjustment mechanism consists of an adjusting screw, a threaded sleeve, an adjusting motor, and a controller 105. The adjusting motor drives the threaded sleeve to move along the adjusting screw, thereby adjusting the position of the first conveyor 102. By adjusting the distance between the first and second conveyors 103, circuit boards of different sizes can be accommodated, improving the versatility of the equipment. The motor-driven spacing adjustment reduces manual intervention and improves the automation level of material feeding.
[0031] The printing system 201 includes a first mounting base 202, a second mounting base 204, and a printing arm 205 mounted on the second mounting base 204. The first mounting base 202 is provided with a lifting component 203 for connecting to the second mounting base 204. The second mounting base 204 is provided with a translation component 207 for connecting to the printing arm 205. The second mounting base 204 is also provided with an adjustable clamping mechanism that can be adapted to circuit boards of different sizes.
[0032] In this embodiment, the second mounting base 204 moves vertically along the first mounting base 202 via the lifting assembly 203 (lifting guide rail and slide one) to adjust the height of the printing template. The printing arm 205 moves horizontally along the second mounting base 204 via the translation assembly 207 (translation guide rail and slide two) to adjust the printing position. There are two scraper heads 208, which move vertically downward via the first cylinder assembly 206 to scrape solder paste. The adjustable clamping mechanism consists of a mounting frame 209, first / second clamping arms 212, and a second cylinder assembly 210. The second cylinder assembly 210 drives the mounting frame 209 to move, and the mounting frame 209, equipped with clamping arms, fixes the circuit board. The first clamping arms 211 and the second clamping arms 212 can be adjusted in position via an electrically adjustable guide rail to accommodate circuit boards of different sizes.
[0033] The system is applicable to products of various sizes and features a modular design, allowing for flexible configuration and upgrades, and facilitating maintenance and replacement. The fully automated process reduces manual intervention and improves production efficiency. Quality inspection is performed via the CDD vision inspection module 303 of the inspection system 301. The CDD vision inspection module 303 is connected to an alarm module located on the display terminal. When defective products are detected, an alarm signal is sent to the display terminal, allowing operators to detect them promptly and further improving product quality and reliability. After inspection, the circuit boards undergo accelerated curing of solder paste on their surfaces via two curing units 304, saving time and improving work efficiency.
[0034] Furthermore, a slide rail is provided at the connection between the first conveyor 102 and the first worktable 1, and the second conveyor 103 is fixedly mounted on the first worktable 1. The slide rail allows the first conveyor 102 to move freely within a certain range, with the direction of movement being the direction of the second conveyor 103. The position of the second conveyor 103 is fixed, serving as a reference for adjusting the position of the first conveyor 102 relative to it.
[0035] Furthermore, the spacing adjustment mechanism includes two spacing adjusters 104. Each spacing adjuster 104 includes an adjusting screw and a threaded sleeve fitted onto the adjusting screw. The screw is connected to the first conveyor 102 and the second conveyor 103, respectively. Both the first conveyor 102 and the second conveyor 103 are equipped with a controller 105 and an adjusting motor. Using two spacing adjusters 104 achieves more stable and precise spacing adjustment. Simultaneous adjustment of the two screws prevents the first conveyor 102 and the second conveyor 103 from tilting, ensuring parallelism. This improves the accuracy and stability of the adjustment.
[0036] Furthermore, the adjusting motor is connected to the controller 105, and the threaded sleeve is fixedly mounted on the first conveyor 102. The threaded sleeve moves along the axis of the adjusting screw via the adjusting motor. One end of the adjusting screw is connected to the first conveyor 102, and the other end is connected to the second conveyor 103. In this way, the movement of the threaded sleeve directly drives the movement of the conveyors, thereby changing the distance between them.
[0037] To further explain, the first mounting base 202 is vertically fixed on one side of the second workbench 2, the second mounting base 204 moves along the vertical direction of the first mounting base 202 via the lifting assembly 203, the slide is connected to the translation assembly 207, and the printing arm 205 moves along the horizontal direction of the second mounting base 204 via the translation assembly 207.
[0038] The first mounting base 202 is vertically fixed to one side of the second worktable 2, providing a stable support structure. The second mounting base 204 is mounted on the first mounting base 202 via a lifting assembly 203 and can move along the vertical direction of the first mounting base 202. A slide is connected to a translation assembly 207, allowing the slide to move on a horizontal plane, providing the ability to adjust the horizontal position of the printing arm 205. The slide can move left and right on the second mounting base 204, thereby changing the working position of the printing arm 205. The printing arm 205 is connected to the slide via the translation assembly 207 and can move along the horizontal direction of the second mounting base 204. This allows the printing arm 205 to precisely position the print head to the required position according to different work needs, thereby performing printing or other operations.
[0039] Furthermore, the lifting assembly 203 includes two lifting guide rails mounted on the first mounting base 202 and a first slide connecting the lifting guide rails. The first slide is fixedly connected to the second mounting base 204. The translation assembly 207 includes two translation guide rails mounted on the second mounting base 204 and a second slide for connecting the printing press arm 205. The second slide is connected to the printing press arm 205. The two lifting guide rails are fixed on the first mounting base 202, providing precise guidance for the vertical movement of the second mounting base 204. Their high-precision linear guides ensure smooth and stable movement.
[0040] Furthermore, the printing press arm 205 is provided with a first cylinder assembly 206 and a scraper head 208 connected to the first cylinder assembly 206, and the first cylinder assembly 206 is vertically disposed on the printing press arm 205.
[0041] Furthermore, the adjustable clamping mechanism includes a mounting frame 209 and a first clamping arm 211 and a second clamping arm 212 disposed on the mounting frame 209. The mounting frame 209 is also provided with second cylinder assemblies 210 on both sides. The second cylinder assemblies 210 are disposed on the second mounting base 204. The mounting frame 209 moves along the vertical direction of the second mounting base 204 via the second cylinder assemblies 210.
[0042] Furthermore, there are two of each of the first clamping arms 211 and the second clamping arms 212. The two first clamping arms 211 are symmetrically arranged on the fixed frame, and the two second clamping arms 212 are symmetrically arranged on the fixed frame. Each first clamping arm 211 and the second clamping arm 212 is provided with an electric adjustment guide rail at the connection between it and the frame.
[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
