Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of PCB board production, in particular to a loading mechanism for a printing machine used in PCB board production. Background Technique
[0002] Generally, many electronic components, such as chips, resistors, capacitors, and inductors, are configured on the printed circuit board (PCB) in electronic products to form a circuit with specific functions. Currently, during the production process of PCB boards, due to the limitation of the production workshop site, after the PCB boards are processed in the previous process, they often need to be manually transferred to the next process. Now, a loading mechanism for a printing machine used in PCB board production is required.
[0003] After the existing loading mechanism is transported to the next process, it often requires manual placement of PCB boards one by one on the conveying device of the PCB board production line, making the process of placing PCB boards very cumbersome and wasting a lot of time. In addition, the existing loading mechanism has some disadvantages to a certain extent. When using the loading mechanism, manual feeding of PCB boards is usually required, and it does not have the function of automatic feeding. This makes it impossible to automatically adjust the position of the loading box when using the loading mechanism, and it cannot automatically feed the material frame, reducing the automation level when using the loading mechanism. In order to make the feeding of PCB boards more accurate, precise feeding of PCB boards is required. The existing loading mechanism cannot accurately push the PCB boards when in use, which makes it impossible to automatically push and feed the PCB boards placed inside the material frame when using the loading mechanism, making the loading mechanism inaccurate when in use and prone to skew when feeding the PCB boards, and not precise enough when processing the surface of the PCB boards. The loading mechanism is prone to jamming when feeding. The existing loading mechanism cannot feed quickly when in use, which makes the feeding of PCB boards not fast enough when using the loading mechanism, easily resulting in jamming of PCB boards when feeding during the use of the loading mechanism, and greatly reducing the working efficiency when using the loading mechanism.

[0009] Preferably, the automatic feeding part is arranged inside the fixing plate and on the surface of the feeding box.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The feeding mechanism for the PCB board production printing machine not only enables the feeding mechanism to automatically adjust the position of the feeding box during use, enables the feeding mechanism to automatically feed the material frame, makes the automation degree of the feeding mechanism higher during use, enables the feeding mechanism to automatically push and feed the PCB board bodies placed inside the material frame during use, makes the feeding mechanism more accurate during use, enables the PCB board bodies not to be skewed during feeding, is more accurate when processing the surface of the PCB board bodies, but also enables the PCB board bodies to be fed more quickly during use of the feeding mechanism, avoids the phenomenon of the PCB board bodies getting stuck during feeding in the process of using the feeding mechanism, and greatly improves the working efficiency of the feeding mechanism during use.
[0014] 1. By setting up an automatic feeding mechanism, the driving motor inside the fixed plate is controlled to work. Under the action of the driving motor, the rotating screw rod rotates inside the fixed plate. When the rotating screw rod rotates, the screw barrel body is driven to move inside the fixed plate under the thread fit between the rotating screw rod and the screw barrel body. At this time, the screw barrel body drives the fixed block to slide inside the fixed slot. Under the combined action of the fixed block and the fixed slot, the screw barrel body is guided. When the screw barrel body moves, the screw barrel body drives the feeding box to move on the surface of the fixed plate to one side of the fixed box, realizing the automatic feeding function of the feeding mechanism. Thus, when the feeding mechanism is used, the position of the feeding box can be automatically adjusted, enabling the feeding mechanism to automatically feed the material frame, making the automation degree of the feeding mechanism higher when in use;
[0015] 2. By setting up a precise material pushing mechanism, the electric push rod inside the fixed cylinder is controlled to work. Under the action of the electric push rod, the material pushing plate is driven to move. When the material pushing plate moves, the material pushing plate slides inside the guiding groove. Under the action of the guiding groove, the material pushing plate is guided, enabling the electric push rod to drive one side of the material pushing plate to move inside the fixed box and the material frame. Subsequently, under the combined action of the electric push rod and the material pushing plate, the PCB board body inside the material frame is pushed, causing the PCB board body to slide inside the material frame and be ejected from the inside of the material frame, making the PCB board body fall onto the surface of the conveyor belt for processing the surface of the PCB board body, realizing the precise material pushing function of the feeding mechanism. Thus, when the feeding mechanism is used, it can automatically perform the material pushing and feeding process on the PCB board body placed inside the material frame, making the feeding mechanism more precise when in use, preventing the PCB board body from skewing during feeding, and being more precise when processing the surface of the PCB board body;
[0016] 3. By setting up a rapid feeding mechanism, when the PCB board body slides inside the material frame, at this time, the user places the mounting frames on the inner walls of the material frame as needed and pushes the mounting frames, causing the mounting frames to drive the mounting fasteners to be clamped to the inner walls of the material frame, thereby installing the mounting frames on the inner walls of the material frame respectively. When the PCB board body slides inside the material frame, at this time, the PCB board body drives the rotating balls to rotate on the surface of the rolling groove. Under the combined action of the rotating balls and the rolling groove, the PCB board body moves more labor - saving and quickly inside the material frame during feeding, making the PCB board body less likely to get stuck during feeding, realizing the rapid feeding function of the feeding mechanism. Thus, when the feeding mechanism is used, the PCB board body is fed more quickly, avoiding the phenomenon that the PCB board body gets stuck during feeding in the process of using the feeding mechanism, and greatly improving the working efficiency of the feeding mechanism when in use.

The adjusting screws 114 are rotatably matched with the inner wall of the fixed box 116. Rotating motors 113 are installed inside the fixed box 116. The model of the rotating motor 113 can be selected from the JO series. The input end of the rotating motor 113 is electrically connected to the output end of the control button 108. The output end of the rotating motor 113 is installed with a rotating shaft through a coupling, and one end of the rotating shaft is fixed to the surface of the adjusting screw 114. An adjusting nut 115 is sleeved on the surface of the adjusting screw 114. The surface of the adjusting nut 115 is fixed to the surface of the lifting frame 103. The lifting frame 103 is slidably matched with the inner wall of the fixed box 116.
[0027] Further, as Figure 3 and Figure 5As shown, a precise feeding mechanism 2 is provided on the surface of the support frame 110 and the PCB board body 112. The inside of the precise feeding mechanism 2 includes a position sensor 21, a pushing plate 22, and a precise feeding part 23. The precise feeding part 23 is arranged on the surface of the support frame 110 and the PCB board body 112. The precise feeding part 23 is composed of an electric push rod 231, a fixed cylinder 232, and a guide groove 233. The position sensor 21 is installed on the surface of the lifting frame 103, the fixed cylinder 232 is installed on the inner wall of the support frame 110, the electric push rod 231 is installed inside the fixed cylinder 232. The model of this electric push rod 231 can be selected from the DG series. The input end of the electric push rod 231 is electrically connected to the output end of the control button 108. Guide grooves 233 are formed on the inner walls of the fixed cylinder 232. The output end of the electric push rod 231 penetrates through the fixed box 116 and extends to one side of the PCB board body 112. The output end of the electric push rod 231 is equipped with a pushing plate 22. The pushing plate 22 is slidably matched with the inner wall of the guide groove 233. The surface of the pushing plate 22 is in contact with the surface of the PCB board body 112.
[0028] During implementation, under the action of the position sensor 21, the height position of the lifting frame 103 is monitored, so that the PCB board body 112 to be loaded can be located above the conveyor belt 106. Subsequently, the user operates the control button 108, so that the control button 108 controls the electric push rod 231 inside the fixed cylinder 232 to work. Under the action of the electric push rod 231, the pushing plate 22 is driven to move. When the pushing plate 22 moves, the pushing plate 22 slides inside the guide groove 233. Under the action of the guide groove 233, the pushing plate 22 is guided, so that the electric push rod 231 drives one side of the pushing plate 22 to move into the fixed box 116 and the material frame 102. Subsequently, under the combined action of the electric push rod 231 and the pushing plate 22, the PCB board body 112 inside the material frame 102 is pushed, so that the PCB board body 112 slides inside the material frame 102, and the PCB board body 112 is pushed out of the inside of the material frame 102, so that the PCB board body 112 falls onto the surface of the conveyor belt 106, and the surface of the PCB board body 112 is processed to realize the function of precise feeding of the feeding mechanism.
[0029] Furthermore, as Figure 3 and Figure 6As shown in the figure, automatic feeding mechanisms 3 are provided on the inside of the fixing plate 101 and the surface of the feeding box 109. The inside of the automatic feeding mechanism 3 includes a driving motor 31, a rotating screw 32, and an automatic feeding part 33. The automatic feeding part 33 is arranged on the inside of the fixing plate 101 and the surface of the feeding box 109. The automatic feeding part 33 is composed of a screw barrel body 331, a fixing groove 332, and a fixing block 333. A driving motor 31 is installed inside the fixing plate 101. The model of the driving motor 31 can be selected from the JO series. The input end of the driving motor 31 is electrically connected to the output end of the control button 108. The output end of the driving motor 31 is installed with a rotating rod through a coupling. A rotating screw 32 is arranged inside the fixing plate 101. The rotating screw 32 is rotatably matched with the inner wall of the fixing plate 101. The surface of the rotating screw 32 is fixed to the surface of the rotating rod. A screw barrel body 331 is sleeved on the surface of the rotating screw 32 in a threaded manner. A fixing block 333 is installed on the surface of the screw barrel body 331. A fixing groove 332 is formed on the inner wall of the fixing plate 101. The surface of the fixing groove 332 is slidably matched with the surface of the fixing block 333. The surface of the screw barrel body 331 is fixed to the surface at the bottom of the feeding box 109.
[0030] During implementation, the driving motor 31 inside the fixing plate 101 is controlled to work. Under the action of the driving motor 31, the rotating screw 32 rotates inside the fixing plate 101. When the rotating screw 32 rotates, under the threaded cooperation of the rotating screw 32 and the screw barrel body 331, the screw barrel body 331 is driven to move inside the fixing plate 101. At this time, the screw barrel body 331 drives the fixing block 333 to slide inside the fixing groove 332. Under the combined action of the fixing block 333 and the fixing groove 332, the screw barrel body 331 is guided. When the screw barrel body 331 moves, the screw barrel body 331 drives the feeding box 109 to move on the surface of the fixing plate 101 to one side of the fixing box 116, so as to realize the automatic feeding function of the feeding mechanism.
[0031] Furthermore, as Figure 4 and Figure 7 shown, quick feeding mechanisms 4 are provided on the inside of the material frame 102 and the surface of the PCB board body 112. The inside of the quick feeding mechanism 4 includes a mounting frame 41, a rolling groove 42, a rotating ball 43, and a mounting clip 44. Mounting frames 41 at equal intervals are provided on the inner walls on both sides of the material frame 102. One end of the mounting frame 41 extends into the inside of the material frame 102. Mounting clips 44 for positioning and installing the mounting frame 41 are installed on the inner walls of the mounting frames 41. The mounting clips 44 are clamped and matched with the inner wall of the material frame 102. Equally spaced rolling grooves 42 are formed on the inner walls of the mounting frames 41. A rotating ball 43 is arranged on the surface of the rolling groove 42. The rotating ball 43 is rotatably matched with the surface of the rolling groove 42. The surface of the rotating ball 43 is in contact with the surface of the PCB board body 112.
[0032] During implementation, when the PCB board body 112 slides inside the material frame 102, at this time, the user places the mounting frames 41 on the inner walls of the material frame 102 as needed. The user pushes the mounting frames 41, causing the mounting frames 41 to drive the mounting clips 44 to latch onto the inner walls of the material frame 102, thereby installing the mounting frames 41 on the inner walls of the material frame 102 respectively. When the PCB board body 112 slides inside the material frame 102, at this time, the PCB board body 112 drives the rotating balls 43 to rotate on the surface of the rolling grooves 42. Under the combined action of the rotating balls 43 and the rolling grooves 42, it is more labor-saving and faster for the PCB board body 112 to move inside the material frame 102, and it is not easy for the PCB board body 112 to get stuck during feeding, so as to realize the function of rapid feeding of the feeding mechanism.
[0033] Working principle: When in use, first place the feeding rack 1 at the specified position. The user places the PCB board bodies 112 into the material frame 102 from top to bottom respectively. Subsequently, the user operates the control button 108, causing the control button 108 to control the driving motor 31 inside the fixed plate 101 to work. Under the action of the driving motor 31, the rotating screw 32 rotates inside the fixed plate 101. When the rotating screw 32 rotates, under the thread fit between the rotating screw 32 and the screw barrel body 331, the screw barrel body 331 moves inside the fixed plate 101. At this time, the screw barrel body 331 drives the fixed block 333 to slide inside the fixed groove 332. Under the combined action of the fixed block 333 and the fixed groove 332, the screw barrel body 331 is guided. When the screw barrel body 331 moves, the screw barrel body 331 drives the feeding box 109 to move on the surface of the fixed plate 101 to one side of the fixed box 116, so as to realize the function of automatic feeding of the feeding mechanism, so that the feeding mechanism can automatically adjust the position of the feeding box 109 during use, enabling the feeding mechanism to automatically feed the material frame 102, and making the automation degree of the feeding mechanism higher when in use.
[0034] Subsequently, the user operates the control button 108, causing the control button 108 to control the rotating motor 113 inside the fixed box 116 to work. Under the action of the rotating motor 113, the adjusting screw 114 rotates inside the fixed box 116. Under the thread fit between the adjusting screw 114 and the adjusting screw barrel 115, the adjusting screw barrel 115 moves inside the fixed box 116, thereby driving the lifting frame 103 to move downward inside the fixed box 116, causing the material frame 102 to move into the fixed box 116. Subsequently, the adjusting screw barrel 115 drives the lifting frame 103 to move upward to the specified position, and conveys the PCB board body 112 under the action of the control button 108.
[0035] Subsequently, under the action of the in-place sensor 21, the height position of the lifting frame 103 is monitored so that the PCB board body 112 to be loaded can be located above the conveyor belt 106. Subsequently, the user operates the control button 108, causing the control button 108 to control the electric push rod 231 inside the fixed cylinder 232 to work. Under the action of the electric push rod 231, the pushing plate 22 is driven to move. When the pushing plate 22 moves, the pushing plate 22 slides inside the guiding groove 233. Under the action of the guiding groove 233, the pushing plate 22 is guided, causing the electric push rod 231 to drive one side of the pushing plate 22 to move inside the fixed box 116 and the material frame 102. Subsequently, under the combined action of the electric push rod 231 and the pushing plate 22, the PCB board body 112 inside the material frame 102 is pushed, causing the PCB board body 112 to slide inside the material frame 102, ejecting the PCB board body 112 from inside the material frame 102, and causing the PCB board body 112 to fall onto the surface of the conveyor belt 106, processing the surface of the PCB board body 112 to achieve the function of precise material pushing of the feeding mechanism. Thus, when the feeding mechanism is used, it can automatically perform material pushing and feeding processing on the PCB board body 112 placed inside the material frame 102, making the feeding mechanism more precise when in use, preventing the PCB board body 112 from skewing during feeding, and being more precise when processing the surface of the PCB board body 112.
[0036] Subsequently, when the PCB board body 112 slides inside the material frame 102, at this time, the user places the mounting frame 41 on the inner wall of the material frame 102 as needed. The user pushes the mounting frame 41, causing the mounting frame 41 to drive the mounting clip 44 to latch onto the inner wall of the material frame 102, thereby installing the mounting frame 41 on the inner wall of the material frame 102 respectively. When the PCB board body 112 slides inside the material frame 102, at this time, the PCB board body 112 drives the rotating ball 43 to rotate on the surface of the rolling groove 42. Under the combined action of the rotating ball 43 and the rolling groove 42, the PCB board body 112 moves more labor-saving and quickly inside the material frame 102, preventing the PCB board body 112 from jamming during feeding, to achieve the function of rapid feeding of the feeding mechanism. Thus, when the feeding mechanism is used, the PCB board body 112 is fed more quickly, avoiding the phenomenon of the PCB board body 112 jamming during feeding in the process of using the feeding mechanism, greatly improving the working efficiency of the feeding mechanism when in use, and finally completing the use of the feeding mechanism.
