[0001] The present application relates to the technical field of automatic board placement equipment, and in particular to a small board placement machine. Background Art

[0002] Small circuit boards are widely used in industrial production, particularly in electronics manufacturing. Efficient handling of circuit boards directly impacts the overall efficiency of the production line. To meet the demands of modern production, various types of circuit board placement machines have emerged. These devices not only increase automation but also significantly reduce the need for manual intervention, increasing production capacity while reducing labor costs, profoundly impacting the manufacturing industry.

[0003] Small panels are small in size and need to be placed and transported one by one. They are easily disturbed by external factors during the placement and transportation process, causing conveying deviation. Therefore, manual assistance is required for panel sorting operations, which greatly reduces the degree of automation and the subsequent panel collection accuracy is poor. This problem needs to be solved urgently. Summary of the Invention

[0004] In order to improve the degree of automation in placing small panels and to improve the accuracy of subsequent small panel collection, the present application provides a small panel placing machine.

[0005] This application provides a small board placement machine, which adopts the following technical solutions: The lifting mechanism comprises a lifting mechanism, a lifting mechanism, a lifting mechanism for lifting the lifting plate, and a lifting mechanism for lifting the lifting plate. The lifting mechanism comprises a lifting mechanism for lifting the lifting plate, a lifting mechanism for lifting the lifting plate, a lifting mechanism for lifting the lifting plate, and a lifting mechanism for lifting the lifting plate. The lifting mechanism is located at one end of the automatic lifting mechanism, the transfer mechanism is located between the automatic lifting mechanism and the pressing and conveying mechanism, and is used to smoothly transfer the small plate on the top layer of the stacked small plates to the head end of the conveying direction of the pressing and conveying mechanism, the collecting mechanism is located at one end side of the pressing and conveying mechanism, the sorting mechanism is located between the pressing and conveying mechanism and the collecting mechanism, and is used to detect small plates and sort good and defective small plates, and the collecting mechanism collects good and defective small plates separately, and the control system is electrically connected to the automatic lifting mechanism, the transfer mechanism, the pressing and conveying mechanism, the sorting mechanism and the collecting mechanism.

[0006] By adopting the above technical scheme, the frame supports the automatic loading mechanism, the transfer mechanism, the pressing and conveying mechanism, the sorting mechanism, the plate receiving mechanism and the control system. When it is necessary to place the small plates, the automatic loading mechanism loads the stacked small plates one by one, and then the transfer mechanism smoothly transfers the small plate on the top layer of the stacked small plates to the pressing and conveying mechanism, and the pressing and conveying mechanism smoothly conveys the small plates. When the small plates are conveyed to the end of the conveying direction of the pressing and conveying mechanism, the sorting mechanism detects good and bad products for the small plates and sorts them into the plate receiving mechanism. During the entire small plate placing process, the control system automatically controls the automatic loading mechanism, the transfer mechanism, the pressing and conveying mechanism, the sorting mechanism and the plate receiving mechanism, and the conveying is stable during the plate placing and conveying process, and it is difficult to be disturbed by external factors and cause conveying deviation, which is beneficial to improve the degree of automation of small plate placing and the subsequent small plate receiving accuracy.

[0007] Preferably, the automatic loading mechanism includes a first conveying component, a lifting component and a support plate. The lifting component is arranged on the frame to drive the first conveying component and the support plate to move vertically up and down. The first conveying component is used to convey and adjust the position of stacked small panels. The support plate is vertically fixed on one side of the conveying direction of the first conveying component. When the stacked small panels are placed on the first conveying component, the side edges of the stacked small panels are against the side walls of the support plate.

[0008] By adopting the above technical solution, when it is necessary to perform a plate placing operation, the jacking assembly first drives the first conveying assembly and the back plate to move vertically downward so that the stacked small plates are placed on the first conveying assembly. When the stacked small plates are placed on the first conveying assembly, the side edges of the stacked small plates are against the side walls of the back plate to position the subsequent transfer and conveying operations of the small plates. The first conveying assembly conveys the stacked small plates to a position convenient for the transfer mechanism to perform the transfer operation, and then the jacking assembly drives the first conveying assembly and the back plate to move vertically upward to drive the stacked small plates close to the transfer mechanism, thereby facilitating the transfer mechanism to perform transfer operations on the topmost small plates one by one, with accurate positioning.

[0009] Preferably, the transfer mechanism includes an adsorption component and a second conveying component. The adsorption component is arranged on the frame and located between the first conveying component and the pressing conveying mechanism for adsorbing small panels. The second conveying component is arranged on the adsorption component for transferring the topmost small panels from the first conveying component to the pressing conveying mechanism.

[0010] By adopting the above technical solution, in the process of transferring the small panels from the first conveying component to the pressing conveying mechanism, the second conveying component provides power to drive the small panels on the top layer. During the transfer of the small panels, the adsorption component adsorbs the small panels, and the small panels are unlikely to shake or be disturbed, which is beneficial to improving the stability of the small panel transfer process.

[0011] Preferably, the second conveying assembly includes a horizontally arranged conveying roller and a first driving member for driving the conveying roller to rotate, and the conveying roller is located directly above the small panels in the automatic loading mechanism. When the small panels on the top layer are lifted to abut against the bottom end of the conveying roller, the small panels on the top layer are horizontally facing the entrance of the pressing conveying mechanism.

[0012] By adopting the above technical solution, when it is necessary to transfer the small panels on the top layer, the small panels on the top layer are lifted to abut against the bottom end of the conveying roller, and the first driving member drives the conveying roller to rotate to drive the small panels on the top layer to move toward the direction close to the pressing and conveying mechanism, thereby realizing the transfer of the small panels on the top layer.

[0013] Preferably, the adsorption assembly includes a vacuum box arranged on a frame, the vacuum box is connected to a vacuum suction system, the bottom of the vacuum box is flush with the bottom of the conveying roller, and a plurality of adsorption ports are evenly spaced at the bottom of the vacuum box.

[0014] By adopting the above technical solution, when the rotation of the conveying roller drives the topmost small panel to be transferred from the first conveying assembly to the pressing conveying mechanism, the vacuum suction system is opened to adsorb the moving small panel through the vacuum box and the adsorption port, thereby helping to improve the stability of the small panel during movement, and the topmost small panel will not fall down when leaving the stacked small panel pile.

[0015] Preferably, the adsorption assembly also includes a plurality of opening and closing parts for opening and closing the adsorption port, and the opening and closing parts correspond to the adsorption port one by one. The opening and closing parts include a fixedly connected opening and closing plate and a shift rod. The opening and closing plate is rotatably connected to the inside of the vacuum box corresponding to the position of the adsorption port, and the shift rod is rotatably connected to the outer wall of the vacuum box.

[0016] By adopting the above technical solution, the staff controls the adsorption force of the adsorption port by opening and closing the opening and closing parts of the adsorption port, thereby facilitating the control of the adsorption effect on small panels of different specifications and sizes. The staff controls the rotation of the opening and closing plate by turning the lever to realize the opening and closing of the adsorption port, which is convenient, fast and easy to control.

[0017] Preferably, the pressing and conveying mechanism includes a third conveying component and a pressing component. The third conveying component is arranged on the frame for receiving and conveying small panels transferred from the automatic loading mechanism. The pressing component is connected to the frame and is located above the third conveying component. A channel is formed between the pressing component and the third conveying component for the passage of clamped small panels.

[0018] By adopting the above technical solution, the third conveying component takes over the conveying of the small panels transferred from the automatic loading mechanism. While the small panels are being conveyed on the third conveying component, the pressing component applies pressing force to the small panels being conveyed to achieve clamping and conveying. The small panels are unlikely to shake or be disturbed during the conveying process on the third conveying component, which is beneficial to improving the stability of the small panels during the conveying process.

[0019] Preferably, the pressing assembly includes a pressing roller and an elastic connecting member, one end of the elastic connecting member is connected to the frame, the pressing roller is rotatably connected to the other end of the elastic connecting member, and the pressing roller is located directly above the conveying position of the third conveying assembly. When the small plate is conveyed on the third conveying assembly, the pressing roller presses against the upper surface of the small plate.

[0020] By adopting the above technical solution, when the small panel is conveyed on the third conveying assembly, the pressing roller applies pressing force to the small panel under the action of the elastic connecting member, so that the pressing roller and the third conveying assembly form a clamping conveying shape, which is beneficial to improving the stability of the conveying process of the small panel on the third conveying assembly. The pressing roller is set to rotate to facilitate the movement process of the small panel.

[0021] Preferably, the pressing components are provided in several groups, and the several groups of pressing components are arranged at intervals along the conveying direction of the third conveying component, and the pressing components are arranged in two rows along the width direction of the third conveying component, and the two rows of pressing components are respectively pressed against the opposite sides of the small plate.

[0022] By adopting the above-mentioned technical solution, several groups of pressing components are arranged at intervals along the conveying direction of the third conveying component, which can ensure the stability of the small panel during the entire conveying process on the third conveying component. The two rows of pressing components are pressed against the opposite sides of the small panel respectively, which is conducive to further improving the stability of the small panel during conveyance on the third conveying component.

[0023] Preferably, the pressing and conveying mechanism also includes an adjusting component for adjusting the interval between the two rows of pressing components. The position of one row of pressing components is stationary, and the adjusting component is arranged on the frame to drive the other row of pressing components to move toward or away from the stationary pressing component.

[0024] By adopting the above technical solution, when the specifications of the small panel change, the adjustment component drives one column of pressing components to move toward or away from another column of pressing components, so that the two columns of pressing components can stably provide pressing force to the two opposite sides of the small panel, which is beneficial to improving the applicability of the two columns of pressing components in providing stabilization.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up an automatic loading mechanism, a transfer mechanism, a pressing and conveying mechanism, a sorting mechanism, a plate receiving mechanism and a control system, when it is necessary to place the small plates, the automatic loading mechanism loads the stacked small plates one by one, and then the transfer mechanism smoothly transfers the small plate on the top layer of the stacked small plates to the pressing and conveying mechanism, and the pressing and conveying mechanism smoothly conveys the small plates. When the small plates are conveyed to the end of the conveying direction of the pressing and conveying mechanism, the sorting mechanism detects good and bad products for the small plates and sorts them into the plate receiving mechanism. During the entire small plate placing process, the control system automatically controls the automatic loading mechanism, the transfer mechanism, the pressing and conveying mechanism, the sorting mechanism and the plate receiving mechanism, and the conveying is stable during the plate placing and conveying process, and it is difficult to be disturbed by external factors and cause conveying deviation, which is beneficial to improving the degree of automation of small plate placing and the subsequent small plate receiving accuracy.

[0026] 2. By setting up an adsorption component and a second conveying component, in the process of transferring the small panel from the first conveying component to the pressing conveying mechanism, the second conveying component provides power to drive the small panel on the top layer. During the transfer of the small panel, the adsorption component adsorbs the small panel, and the small panel is unlikely to shake or be disturbed, which is beneficial to improve the stability of the small panel transfer process.

[0027] 3. By setting up a third conveying component and a pressing component, the third conveying component undertakes the conveying of small panels transferred from the automatic loading mechanism. While the small panels are being conveyed on the third conveying component, the pressing component applies pressing force to the small panels being conveyed to achieve clamping and conveying.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] The embodiment of the present application discloses a small board placing machine, referring to Figure 1 and Figure 2, including a frame 1, on which are provided an automatic loading mechanism 2, a transfer mechanism 3, a pressing and conveying mechanism 4, a sorting mechanism 5, a board receiving mechanism 6 and a control system 7. The frame 1 integrates the automatic loading mechanism 2, the transfer mechanism 3, the pressing and conveying mechanism 4, the sorting mechanism 5, the board receiving mechanism 6 and the control system 7 and plays a supporting role. Specifically, the automatic loading mechanism 2 is arranged at the head end of the frame 1 and is used to automatically load the stacked small panels one by one. The pressing and conveying mechanism 4 is located on one side of the discharging direction of the automatic loading mechanism 2. The transfer mechanism 3 is located between the automatic loading mechanism 2 and the pressing and conveying mechanism 4 and is used to smoothly transfer the topmost small panel in the stacked small panels to the head end of the conveying direction of the pressing and conveying mechanism 4. The collecting mechanism 6 is located on the end side of the pressing and conveying mechanism 4. The sorting mechanism 5 is located between the pressing and conveying mechanism 4 and the collecting mechanism 6 and is used to detect small panels and sort the good and defective small panels. The collecting mechanism 6 collects the good and defective small panels separately. It should be noted that the control system 7 is electrically connected to the automatic loading mechanism 2, the transfer mechanism 3, the pressing and conveying mechanism 4, the sorting mechanism 5 and the collecting mechanism 6. In this embodiment, the control system 7 is controlled by a PLC system. The entire process of placing and conveying small panels is highly stable and is not easily disturbed by external factors, causing conveying deviation. The system also has a high degree of automation, which is beneficial to improving the subsequent collection accuracy of small panels.

[0037] Reference Figure 2 The automatic loading mechanism 2 includes a first conveying assembly 21, a lifting assembly 22, and a support plate 23. The lifting assembly 22 is arranged on the frame 1 to drive the first conveying assembly 21 and the support plate 23 to move vertically up and down. The first conveying assembly 21 is used to convey and adjust the position of the stacked small panels. The support plate 23 is vertically fixed on one side of the conveying direction of the first conveying assembly 21. When the stacked small panels are placed on the first conveying assembly 21, the side edges of the stacked small panels abut against the side walls of the support plate 23 to position the small panels for subsequent conveying. In this embodiment, the first conveying assembly 21 is configured in the form of a conveyor belt. The stacked small panels are placed on the conveyor belt and one side of the small panels abuts against the support plate 23. The conveyor belt adjusts the position of the stacked small panels so that the transfer mechanism 3 can transfer the topmost small panels.

[0038] Reference Figure 2The lifting assembly 22 includes a lifting frame 221 and a lifting drive 222. The first conveying assembly 21 is mounted on the lifting frame 221. The lifting drive 222 is mounted on the frame 1 and is used to drive the lifting frame 221 to move vertically up and down, thereby driving the small panels stacked on the first conveying assembly 21 to move vertically up and down. In this embodiment, the lifting assembly 22 uses a motor screw to drive the lifting frame 221, which will not be described in detail here. It should be noted that the jacking assembly 22 drives the jacking frame 221 to move vertically up and down and has an upper limit position and a lower limit position. The jacking frame 221 descends to the lower limit position to facilitate the staff to place the stacked small panels on the first conveying assembly 21, and then performs intermittent jacking operations under the control of the control system 7 to lift the small panels one by one to the action position of the transfer mechanism 3 for transfer operations. When the jacking frame 221 is lifted to the upper limit position, all the small panels on the first conveying assembly 21 are transferred. At this time, the jacking assembly 22 drives the jacking frame 221 to move vertically downward to the lower limit position to perform the next batch of small panel placement operations.

[0039] Reference Figure 2 and Figure 3 The transfer mechanism 3 includes an adsorption component 31 and a second conveying component 32. The adsorption component 31 is arranged on the frame 1 and is located between the first conveying component 21 and the pressing conveying mechanism 4. It is used to adsorb small panels to prevent small panels from falling during the transfer process and improve the stability of the small panel transfer process. The second conveying component 32 is arranged on the adsorption component 31 to transfer the topmost small panels from the first conveying component 21 to the pressing conveying mechanism 4, thereby realizing the transfer of small panels.

[0040] Reference Figure 2 and Figure 3 The second conveyor assembly 32 includes a horizontally arranged conveyor roller 321 and a first driving member 322 for driving the conveyor roller 321 to rotate. The conveyor roller 321 is located directly above the small panels on the first conveyor assembly 21. When the topmost small panels are lifted to abut against the bottom end of the conveyor roller 321, the topmost small panels are horizontally facing the entrance of the pressing conveyor mechanism 4. The first driving member 322 drives the conveyor roller 321 to rotate, driving the topmost small panels toward the entrance of the pressing conveyor mechanism 4. In this embodiment, the first driving member 322 uses a motor, a wheel set, and a belt structure to drive the conveyor roller 321, which will not be described in detail here.

[0041] Reference Figure 2 and Figure 3The adsorption assembly 31 includes a vacuum box 311 fixedly mounted on the frame 1. The vacuum box 311 is connected to the vacuum suction system. The bottom of the vacuum box 311 is flush with the bottom of the conveying roller 321, and the bottom of the vacuum box 311 is evenly spaced along the length of the conveying roller 321. A number of adsorption ports are provided at intervals. When the conveying roller 321 drives the topmost small plate to move, a negative pressure is formed in the vacuum box 311 and the small plate is adsorbed through the adsorption ports, so that the small plate will not fall during the movement and is conducive to improving the stability of the movement. It is worth mentioning that the number of conveying rollers 321 is set to two, and the two conveying rollers 321 are located on the front and back sides of the vacuum box 311 to further improve the stability of the transfer of small plates.

[0042] Reference Figure 2 and Figure 3 The adsorption assembly 31 also includes a number of opening and closing parts 312 for opening and closing the adsorption port. The number of opening and closing parts 312 is the same as the number of adsorption ports, and the opening and closing parts 312 correspond to the adsorption ports one by one. Specifically, the opening and closing parts 312 include a fixedly connected opening and closing plate (the opening and closing plate is inside the vacuum box 311, not shown in the figure) and a lever 3121. The opening and closing plate is rotatably connected to the inside of the vacuum box 311 at the position corresponding to the adsorption port. One end of the opening and closing plate is a rotating end, and the other end is a movable end. The rotating end of the opening and closing plate is rotatably connected to one side of the adsorption port. The lever 3121 is rotatably connected to the outer wall of the vacuum box 311, and the lever 3121 penetrates into the vacuum box 311 and is fixedly connected to the rotating end of the opening and closing plate, so that the staff can drive the opening and closing plate to rotate by toggling the lever 3121, thereby realizing the opening and closing of the adsorption port. By adjusting the number of adsorption ports opened to adjust the adsorption strength, small plate parts of different specifications and sizes can be adsorbed and conveyed, and the applicability is strong.

[0043] Reference Figure 4 and Figure 5 The pressing and conveying mechanism 4 includes a third conveying component 41 and a pressing component 42. The third conveying component 41 is arranged on the frame 1 for receiving and conveying the small panels transferred from the first conveying component 21. The pressing component 42 is connected to the frame 1 and is located above the third conveying component 41. A passage for clamping the small panels is formed between the pressing component 42 and the third conveying component 41. During the conveying process of the small panels by the third conveying component 41, the pressing component 42 applies a downward pressing force to the small panels being conveyed. The pressing component 42 and the third conveying component 41 achieve a clamping state to improve the stability of the small panels being conveyed in the third conveying component 41. In this embodiment, the third conveying component 41 also uses a conveyor belt to convey the small panels, which will not be described in detail here.

[0044] Reference Figure 4 and Figure 5The pressing assembly 42 includes a pressing roller 421 and an elastic connector 422. One end of the elastic connector 422 is connected to the frame 1, and the pressing roller 421 is rotatably connected to the other end of the elastic connector 422. The pressing roller 421 is located directly above the conveying position of the conveyor belt in the third conveyor assembly 41. When the small plate is conveyed on the conveyor belt of the third conveyor assembly 41, the pressing roller 421 presses against the upper surface of the small plate, and the rotation of the pressing roller 421 facilitates the movement of the small plate. In this embodiment, the elastic connector 422 adopts an integrally formed connecting rod and an annular spring plate structure. The pressing roller 421 is rotatably mounted on the connecting rod, and the annular spring plate is fixed to the frame 1. While ensuring structural strength, it can provide sufficient pressing force.

[0045] Reference Figure 4 and Figure 5 The pressing assemblies 42 are provided in several groups, and the groups of pressing assemblies 42 are arranged at intervals along the conveying direction of the third conveying assembly 41 to ensure the stability of the small panels during the entire conveying process on the third conveying assembly 41. At the same time, the pressing assemblies 42 are arranged in two rows along the width direction of the conveyor belt of the third conveying assembly 41. The two rows of pressing assemblies 42 respectively press on opposite sides of the small panels to further improve the stability of the small panels during conveying on the third conveying assembly 41.

[0046] Reference Figure 4 and Figure 5 The pressing and conveying mechanism 4 also includes an adjustment assembly 43 for adjusting the spacing between the two rows of pressing assemblies 42. One row of pressing assemblies 42 remains stationary, and the adjustment assembly 43 is disposed on the frame 1 and is used to drive the other row of pressing assemblies 42 to move toward or away from the stationary pressing assemblies 42, thereby achieving a pressing and conveying operation for small panels of different widths. In this embodiment, the adjustment assembly 43 uses a cylinder and a connecting plate structure to drive one row of pressing assemblies 42. That is, one row of pressing assemblies 42 is connected to the connecting plate, and the cylinder drives the connecting plate to move toward or away from the other row of pressing assemblies 42 to achieve a change in the spacing between the two rows of pressing assemblies 42. This will not be described in detail here.

[0047] Reference Figure 6The sorting mechanism 5 is arranged at the end of the conveying direction of the third conveying assembly 41. Specifically, the sorting mechanism 5 includes a code reader 51 and a suction cup assembly 52. ​​The code reader 51 and the suction cup assembly 52 are both electrically connected to the control system 7. The code reader 51 is connected to the frame 1 and is located at the end of the conveying direction of the third conveying assembly 41 to detect the small panels conveyed from the third conveying assembly 41, and the detection structure is fed back to the control system 7. The control system 7 then sends an electrical signal to the suction cup assembly 52 to separate the good and defective small panels in the receiving mechanism 6. In this embodiment, the suction cup assembly 52 adopts a structure that drives the suction cup to move along the X, Y, and Z axes to operate, which will not be described in detail here. It should be noted that the receiving mechanism 6 has a good product placement area 8 and a defective product placement area 9. The defective small panels are sucked into the defective product placement area 9 by the suction cup assembly 52 for stacking and placement, and the good small panels continue to be transported backward in the good product placement area 8 for collection.

[0048] The implementation principle of a small panel placing machine in the embodiment of the present application is as follows: when it is necessary to place the small panels, the lifting drive member 222 first drives the first conveyor assembly 21 to descend to the lower limit position through the lifting plate, and the staff places the stacked small panels on the first conveyor assembly 21, and makes one side of the small panels abut against the side wall of the support plate 23, and the first conveyor assembly 21 conveys the stacked small panels so that the small panels on the top layer are aligned with the conveyor roller 321 in the vertical direction, and then the lifting drive member 222 performs intermittent lifting operation so that each small panel on the top layer can abut against the lower end of the conveyor roller 321, and in the process of transferring from the first conveyor assembly 21 to the third conveyor assembly 41, the rotating conveyor roller 321 presses the top small panels. The small plate provides conveying power. At the same time, negative pressure is formed in the vacuum box 311 and the small plate is adsorbed through the adsorption port, so that the small plate will not fall during the movement and it is beneficial to improve the stability of the movement. When the small plate is transferred to the third conveying component 41, the pressing component 42 applies a downward pressing force to the small plate in conveyance, and the pressing component 42 and the third conveying component 41 achieve a clamping state to improve the stability of the small plate in the third conveying component 41. The entire plate placement and conveying process is automatically controlled by the control system 7 without manual intervention, and the small plate is conveyed stably and is difficult to be disturbed by external factors to cause conveying deviation, which is beneficial to improve the degree of automation of small plate placement and the subsequent small plate collection accuracy.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
