[0002] After through-hole components are inserted into the PCB, a certain percentage of these components exhibit defects such as poor insertion or floating. These defects need to be inspected and properly aligned before wave soldering. Currently, most component pressing is done manually, which is inefficient and prone to errors, leading to defective products during subsequent wave soldering of the PCB. Utility Model Content
[0003] The main purpose of this invention is to provide a pressing component and AOI inspection equipment to ensure the quality of PCB board pressing components and facilitate subsequent soldering and fixing of the PCB board.
[0004] To achieve the above objectives, the present invention provides a pressing component and AOI inspection equipment, comprising:
[0005] A conveying device, the conveying device being used to transport PCB boards of components to be pressed after insertion;
[0006] A testing device, wherein the testing device is used to perform component insertion testing on the PCB board on the conveying device; and
[0007] A pressing device is electrically connected to the detection device. The pressing device includes a pressing operation component and a pressing drive component that drives the pressing operation component. The pressing drive component is used to drive the pressing operation component to move to a position opposite to the PCB board when the detection device detects that the PCB board is inserted correctly, and to drive the pressing operation component to move toward the surface of the PCB board to press the PCB board.
[0008] In one embodiment, the pressing operation assembly includes a mounting frame and a plurality of pressing heads disposed on the mounting frame. The plurality of pressing heads are used to press the plugs of the PCB board along the Z-axis direction to press the PCB board.
[0009] In one embodiment, a plurality of the pressing heads are elastically connected to the mounting frame, and each pressing head can elastically float relative to the mounting frame along the Z-axis direction.
[0010] In one embodiment, the output end of the pressing component drive assembly is provided with a mounting component, and the pressing component operation assembly further includes a mounting mating component, wherein the mounting component and the mounting mating component are detachably connected.
[0011] In one embodiment, the pressing and AOI inspection equipment further includes a quick-change placement rack, which is disposed adjacent to the pressing device and is used to place the pressing operation components.
[0012] In one embodiment, the conveying device has a first conveying section and a second conveying section connected along the conveying direction, and the pressing and AOI inspection equipment further includes an information identification device, which is disposed opposite to the first conveying section and the inspection device is disposed opposite to the second conveying section;
[0013] The information identification device is electrically connected to the pressing device. The information identification device is used to identify the PCB board on the first conveying section. The detection device is used to detect the plug-in components on the PCB board on the second conveying section. The pressing device is used to match the corresponding pressing operation component according to the identification information of the information identification device.
[0014] In one embodiment, the pressing device further includes a base, and the pressing drive assembly includes a first drive member, a first swing arm, a second swing arm, a second drive member, and a third drive member. The first drive member is disposed on the base and is driven to connect to the first swing arm to drive the first swing arm to rotate around the Z-axis. The second drive member is disposed at the end of the first swing arm away from the first drive member and is driven to connect to the second swing arm to drive the second swing arm to rotate around the Z-axis. The third drive member is disposed at the end of the second swing arm away from the second drive member and is driven to connect to the pressing operation assembly for driving the pressing operation assembly to move up and down along the Z-axis.
[0015] In one embodiment, the detection device includes a light source and an imaging component. The light source is used to provide supplemental lighting for the PCB board of the component to be pressed, and the imaging component is used to acquire image information of the PCB board of the component to be pressed.
[0016] In one embodiment, the pressing and AOI inspection equipment further includes a screening device, which includes a waste storage component. The conveying device is electrically connected to the inspection device and is used to transport the PCB board with the incorrect insertion position to the waste storage component when the inspection device detects an error in the PCB board insertion.
[0017] In one embodiment, the screening device further includes a conveying component and a switching drive component. The waste storage component has a receiving station that docks with the conveying component and a storage station located away from the receiving station. The switching drive component is used to drive the waste storage component to reciprocate between the receiving station and the storage station. The conveying component is used to receive the PCB board conveyed by the conveying device and convey the PCB board to the waste storage component located at the receiving station.
[0018] In one embodiment, the pressing and AOI inspection equipment further includes a chassis, in which the conveying device, the pressing device, and the inspection device are disposed. The screening device is disposed on one side of the chassis. The chassis has an input port and an output port, the input port corresponding to the input end of the conveying device, and the output port corresponding to the output end of the conveying device.
[0019] The technical solution of this utility model uses a conveying device to transport the PCB board after insertion, and a detection device to detect the insertion of the PCB board. If the PCB board is found to have correct insertion, the pressing device drives the pressing operation component to press the PCB board. This avoids pressing the PCB board if there are incorrect insertion positions, insertion angle deviations, misinsertion, or omissions, which could lead to the scrapping of the PCB board. At the same time, pressing the PCB board with correct insertions prevents insufficient insertion depth and insertion floating, thus ensuring that the PCB board insertion meets the requirements, ensuring the quality of PCB board pressing, and facilitating subsequent soldering and fixing of the PCB board. Furthermore, since the pressing device and the detection device are integrated on the same equipment, and with the cooperation of the conveying device, the overall structure of the equipment can be improved, and the pressing operation can be performed immediately after the PCB board is detected, resulting in a faster overall operation cycle.

[0032] After through-hole component insertion on the PCB, a certain percentage of these components exhibit defects such as poor insertion or floating. These defects need to be inspected and properly aligned before wave soldering. Currently, most component pressing is done manually, with pre-reflow AOI (Automated Optical Inspection) typically used to check for errors. However, prolonged manual operation leads to fatigue, errors, and uncontrollable quality. Furthermore, defects detected by pre-reflow AOI require immediate line stoppage and manual intervention, impacting efficiency.
[0033] This utility model proposes a pressing component and AOI inspection equipment 100.
[0034] Please see Figures 1 to 5 In one embodiment of this utility model, the pressing and AOI inspection equipment 100 includes a conveying device 10, an inspection device 20, and a pressing device 30. The conveying device 10 is used to convey the PCB board to be pressed after insertion. The inspection device 20 is used to perform insertion inspection on the PCB board on the conveying device 10. The pressing device 30 is electrically connected to the inspection device 20. The pressing device 30 includes a pressing operation component 31 and a pressing drive component 32 that drives the pressing operation component 31. When the inspection device 20 detects that the PCB board insertion is correct, the pressing drive component 32 drives the pressing operation component 31 to move to a position opposite to the PCB board and drives the pressing operation component 31 to move toward the surface of the PCB board to press the PCB board.
[0035] The correct PCB board insertion includes the correct placement of components on the PCB board, and each component being in its designated position after insertion. The pressing and AOI inspection equipment 100 of this invention also includes a control device, with the pressing device 30 electrically connected to the inspection device 20 via the control device. The pressing operation component 31 may be equipped with multiple pressing heads 312, the arrangement of which can correspond to the arrangement of components on the PCB board. The pressing drive component 32 can drive the insertion operation component to move in multiple directions to adjust the relative position of the pressing drive operation component 31 and the surface of the PCB board to be pressed. The detection device 20 may include a vision detection component, which can visually scan the PCB board to obtain image information of the PCB board surface after the components are inserted. The control device compares the obtained image information with the pre-stored information in the database. When the components on the PCB board are correct and each component is in the designated position after insertion, and there is no insertion angle deviation, misinsertion, or omission of components, the PCB board is detected as correctly inserted. In this case, the control device controls the pressing drive component 32 of the pressing device 30 to work. The pressing drive component 32 drives the pressing operation component 31 to move relative to the PCB board surface. Specifically, when multiple pressing heads 312 are relative to multiple components on the PCB board surface, the pressing drive component 32 drives the pressing operation component 31 to move toward the PCB board surface. The multiple pressing heads 312 press the components simultaneously to ensure that the components are inserted in place, avoiding the situation where the correct components are not fully inserted and the components on the PCB board are floating. When the vision inspection component detects that there are incorrect plug-in positions, incorrect plug-in angles, incorrect insertions, or missing plug-ins on the PCB board, the control device controls the pressing device 30 not to press the PCB board, and directly controls the conveying device 10 to pass the PCB board with incorrect plug-ins out of the pressing and AOI inspection equipment 100, so as to avoid the pressing device 30 blindly pressing the plug-ins and causing the PCB board to be scrapped.
[0036] The technical solution of this utility model uses a conveying device 10 to transport the PCB board after insertion, and a detection device 20 to detect the insertion on the PCB board. If the PCB board insertion is correct, the pressing device 30 uses a pressing drive assembly 32 to drive a pressing operation assembly 31 to press the PCB board. This avoids pressing the PCB board if there are incorrect insertion positions, insertion angle deviations, misinsertion, or omissions, which could lead to PCB board scrap. At the same time, pressing the PCB board with correct insertions by the pressing device 30 avoids insufficient insertion depth and insertion floating, thus ensuring that the PCB board insertion meets the requirements and the quality of the PCB board insertion. This facilitates subsequent soldering and fixing of the PCB board and the insertions. Furthermore, since the pressing device 30 and the detection device 20 are integrated on the same equipment, and with the cooperation of the conveying device 10, the overall structure of the equipment can be improved, and the pressing operation can be performed immediately after the PCB board is detected, resulting in a faster overall operation cycle.
[0037] like Figure 2 , Figure 3 , Figure 4 As shown, the pressing operation assembly 31 includes a mounting frame 311 and a plurality of pressing heads 312 disposed on the mounting frame 311. The plurality of pressing heads 312 are used to press the plug of the PCB board along the Z-axis direction to press the PCB board.
[0038] The Z-axis can extend vertically, and the conveying device 10 can transport the PCB board horizontally along the X-axis. The mounting frame 311 is used to mount multiple pressing heads 312. These pressing heads 312 are arranged according to the layout of the components on the PCB board, and their lengths protrude beyond the mounting frame 311. This arrangement corresponds to the length of each component protruding from the PCB board after insertion. With this configuration, when the pressing heads 312 press against the components on the PCB board along the Z-axis, each pressing head 312 presses against each component, ensuring that each component is pressed into place. This simultaneous pressing of multiple components by the pressing heads 312 improves the pressing efficiency of the pressing and AOI inspection equipment 100.
[0039] To avoid rigid collision between the pressing head 312 and the plug during pressing, optionally, multiple pressing heads 312 are elastically connected to the mounting frame 311, and each pressing head 312 can elastically float relative to the mounting frame 311 along the Z-axis direction.
[0040] The pressing head 312 and the mounting frame 311 are elastically connected by a spring and extendably connected along the Z-axis by a telescopic rod, allowing the pressing head 312 to float elastically relative to the mounting frame 311 along the Z-axis. This design avoids rigid collisions between the pressing head 312 and the mounting frame 311 when pressing the insert, thus preventing damage to the insert. Furthermore, by elastically connecting the pressing head 312 and the mounting frame 311 along the Z-axis, the length matching requirements between multiple pressing heads 312 and multiple inserts are reduced, allowing for a certain length matching tolerance between multiple pressing heads 312 and multiple inserts, thereby reducing the assembly cost of the pressing head 312.
[0041] like Figure 3 , Figure 4 As shown, the output end of the pressing drive assembly 32 is provided with a mounting component 34, and the pressing operation assembly 31 further includes a mounting mating component 313. The mounting component 34 and the mounting mating component 313 are detachably connected. This configuration facilitates the replacement of the pressing operation assembly 31 by the pressing device 30. When the pressing and AOI inspection equipment 100 performs pressing operations on other types of PCB boards, the detachable operation of the mounting component 34 and the mounting mating component 313 allows the pressing operation assembly 31 to be replaced with another pressing operation assembly 31. This enables the multiple pressing heads 312 of the pressing operation assembly 31 to match with multiple plug-ins on the PCB board of that type, thereby facilitating the pressing and AOI inspection equipment 100 to perform pressing operations on different types of PCB boards. The mounting component 34 and the mounting mating component 313 can be configured as two mutually mating flanges, which can be connected by bolts and nuts.
[0042] In addition, a quick-change drive structure and a quick-change movable structure can be configured on the mounting component. When the mounting component 34 is connected to the mounting mating component 313, the quick-change drive structure can drive the quick-change movable structure to be inserted into the snap-fit slot of the mounting mating component 313, so that the mounting mating component 313 and the mounting component 34 are connected. When the pressure component drive assembly 32 is replaced with a different pressure component operation assembly 31, the quick-change drive structure can drive the quick-change movable component to separate from the snap-fit slot, so that the mounting component 34 and the mounting mating component 313 are separated, and the pressure component drive assembly 32 can be separated from the pressure component operation assembly 31 to replace the pressure component operation assembly 31 with a different signal.
[0043] like Figure 2 , Figure 3 , Figure 4 As shown, in one embodiment, the pressing and AOI inspection equipment 100 further includes a quick-change placement rack 40, which is disposed adjacent to the pressing device 30 and is used to place the pressing operation assembly 31.
[0044] The quick-change placement rack 40 can be equipped with multiple placement stations, which can be used to place multiple different types of pressing operation components 31. The multiple placement stations can be arranged around the periphery of the pressing device 30. This arrangement makes it easy for the pressing drive component 32 to obtain different types of pressing operation components 31 from different placement stations for installation, and facilitates the pressing device 30 to perform pressing operations on different types of PCB boards.
[0045] The following describes how the pressing and AOI inspection equipment 100 presses different types of PCB boards, such as... Figure 2 As shown, the conveying device 10 has a first conveying section 11 and a second conveying section 12 connected along the conveying direction. The pressing and AOI inspection equipment also includes an information identification device 70, which is arranged opposite to the first conveying section 11, and the inspection device 20 is arranged opposite to the second conveying section 12.
[0046] The information identification device 70 is electrically connected to the pressing device 30. The information identification device is used to identify the PCB board on the first conveying section 11. The detection device 20 is used to detect the plug-in on the PCB board on the second conveying section 20. The pressing device is used to match the corresponding pressing operation component according to the identification information of the information identification device.
[0047] The information identification device 70 can be configured as a barcode scanner, which can be electrically connected to the control device of the pressing and AOI inspection equipment 100. The scanner scans the pre-stored barcode or QR code information on the PCB board and transmits it to the control device. The control device compares the acquired barcode or QR code information with pre-stored information in the database to obtain the PCB board model of the component to be pressed, and transmits this information to the pressing device 30. The pressing device 30, based on the PCB board model, replaces the corresponding pressing operation component 31 from the quick-change placement rack 40. This facilitates the pressing device 30 in pressing different PCB board models. The pressing device 30 can replace the pressing operation component by manually connecting the mounting part 34 to the mounting fitting part 313 of the pressing operation component 31 on the quick-change placement rack 40, allowing for automatic replacement of the corresponding pressing operation component 31. Provided that the mounting component 34 is equipped with a quick-change drive structure, the mounting component 34 can also be connected to the mounting mating component 313 via the quick-change drive structure to automatically change the corresponding model of the pressure component operation assembly 31. No limitation is made here.
[0048] Alternatively, by configuring the conveyor 10 into a first conveyor segment 11 and a second conveyor segment 12, the first conveyor segment 11 and the second conveyor segment 12 can operate independently. When the information identification device 70 is configured corresponding to the first conveyor segment 11 and the detection device 20 is configured corresponding to the second conveyor segment 12, the information identification device 70 can identify the PCB board model in the first conveyor segment 11, and the detection device 20 can detect the insertion status of the PCB board and press the PCB board in the second conveyor segment 12. Thus, the information identification of the PCB board, as well as the pressing detection and pressing operation of the PCB board, can be carried out independently. The PCB board loading and preparation, identification, and PCB board detection and pressing can operate independently without interference, which can improve the working rhythm of the pressing and AOI inspection equipment 100.
[0049] When the first conveyor section 11 and the second conveyor section 12 are set to run independently, independent driving components can be configured for the first conveyor section 11 and the second conveyor section 12. After the first conveyor section 11 is loaded and scanned, the second conveyor section 12 can still perform unloading operations, thereby realizing that the loading and preparation of PCB boards, identification and detection of PCB boards, and pressing of components can run independently without interference.
[0050] The structure of the pressure component drive assembly 32 is described below, such as... Figure 2 , Figure 3 As shown, in one embodiment, the pressing device 30 further includes a base 33, and the pressing drive assembly 32 includes a first drive member 321, a first swing arm 322, a second swing arm 323, a second drive member, and a third drive member. The first drive member 321 is disposed on the base 33 and is driven to connect to the first swing arm 322 to drive the first swing arm 322 to rotate around the Z-axis. The second drive member is disposed at the end of the first swing arm 322 away from the first drive member and is driven to connect to the second swing arm 323 to drive the second swing arm 323 to rotate around the Z-axis. The third drive member is disposed at the end of the second swing arm 323 away from the second drive member and is driven to connect to the pressing operation assembly 31 to drive the pressing operation assembly 31 to move up and down along the Z-axis.
[0051] Understandably, when the pressing device 30 includes a base 33, a first swing arm 322, and a second swing arm 323, the first swing arm 322 can rotate around the Z-axis with the first drive member 321 on the base 33 as the axis, and the second swing arm 323 can rotate around the Z-axis with the end of the first swing arm 322 away from the first drive member 321 as the axis. This allows the pressing operation component 31 located on the second swing arm 323 to have a large range of movement in the horizontal plane with the rotation axis of the first swing arm 322 as the center. This facilitates moving the mounting component 34 directly above the quick-change placement frame 40, and facilitates the third drive member to drive the mounting frame 34 to mate with the mounting mating part 313 of the pressing operation component 31 on the quick-change placement frame 40. This facilitates the pressing device 30 to replace different models of the pressing operation component 31. At the same time, it facilitates moving the pressing operation component 31 directly above the PCB board to be pressed, so that the pressing operation component 31 can be pressed when the third drive member drives it to move up and down along the Z-axis.
[0052] The first driving component 321 can be configured as a motor and a first reducer. The motor is located on the base 33 and is connected to one end of the first swing arm 322 via the first reducer. The second driving component 321 can also be configured as a motor and a second reducer. The motor is located at the other end of the first swing arm 322 and is connected to one end of the second swing arm 323 via the second reducer, allowing both the first and second swing arms 322 and 323 to rotate around the Z-axis. The third driving component can be a cylinder. The output end of the cylinder is connected to a mounting component 34 located at the other end of the second swing arm 323. The cylinder can drive the mounting component 34 to move up and down along the Z-axis, thereby driving the pressing component operating assembly 31 to move up and down along the Z-axis.
[0053] Optionally, the detection device 20 includes a light source and an imaging component. The light source is used to provide supplemental lighting for the PCB board of the component to be pressed, and the imaging component is used to acquire image information of the PCB board of the component to be pressed.
[0054] The shooting component can be configured as a camera and a lens. The shooting end of the camera can face the second conveying section 12, and the lens can be set at the shooting end of the camera. Two shooting components can be set up to cover the front half and the rear half of the second conveying section 12 respectively. Each shooting component can be equipped with a light source. The light source can emit a surface light source to supplement the PCB board, so that the shooting component can accurately obtain the image information of the PCB board to be pressed.
[0055] like Figure 1 , Figure 2 , Figure 5As shown, in one embodiment, the pressing and AOI inspection equipment 100 further includes a screening device 50, which includes a waste storage component 51. The conveying device 10 is electrically connected to the inspection device 20. The conveying device 10 is used to transport the PCB board with the incorrect insertion position to the waste storage component 51 when the inspection device 20 detects that the PCB board insertion is incorrect.
[0056] With this setup, if there is an error in the PCB board insertion, such as incorrect insertion position, incorrect insertion angle, misinsertion, or omission, which prevents the subsequent pressing device 30 from pressing the PCB board, the PCB board with the incorrect insertion can be moved to the waste storage component 51 of the screening device 50 for temporary storage. This prevents the PCB board with the incorrect insertion from occupying the second conveyor section 12, which would prevent the subsequent PCB boards to be pressed from being detected and pressed.
[0057] The structure of the screening device 50 will be further described below, such as... Figure 5 As shown, in one embodiment, the screening device 50 further includes a conveying component 52 and a switching drive component 53. The waste storage component 51 has a receiving station that docks with the conveying component 52 and a storage station away from the receiving station. The switching drive component 53 is used to drive the waste storage component 51 to reciprocate between the receiving station and the storage station. The conveying component 52 is used to receive the PCB board conveyed by the conveying device 10 and convey the PCB board to the waste storage component 51 at the receiving station.
[0058] The conveying assembly 52 may include a conveying roller drive and two rows of conveying rollers arranged opposite each other along the Y-axis. Each conveying roller group may include multiple conveying rollers spaced apart along the X-axis. The conveying roller drive drives the multiple conveying rollers to rotate, so that the conveying assembly 52 can receive PCB boards from the conveying device 10. The waste storage assembly 51 may be provided with multiple support protrusions spaced apart along the X-axis. Each support protrusion may be located between two adjacent conveying rollers. The switching drive assembly 53 may be a cylinder. The multiple support protrusions may be located on two support plates arranged opposite each other along the Y-axis. The cylinder may drive the two support plates to move and lift along the Z-axis, thereby moving and lifting the multiple support protrusions along the Z-axis. When the upper surface of the support protrusion is flush with the conveying surface formed by the tangent of the top of the multiple conveying rollers, the waste storage assembly 51 is in the receiving position, and the multiple conveying rollers can move the material to the multiple support protrusions. When the multiple support protrusions move below the multiple conveying rollers, the waste storage assembly 51 is in the storage position. The component can also be provided with multiple sets of support protrusions along the Z-axis, each set including multiple support protrusions, so that the waste storage component 51 is provided with multiple support parts along the Z-axis, and each support part is used to place a PCB board with defective plug-in, so that the waste storage component 51 can store multiple PCB boards with defective plug-in.
[0059] When the waste storage component 51 is in the storage position, multiple conveyor rollers can continue to convey PCB boards, so that the conveyor component 52 can be used to convey the pressed PCB boards to the next processing position, so that the PCB boards with unqualified plug-in do not affect the pressing and unloading operations of the PCB boards.
[0060] Furthermore, the output end of the conveying device 10 located inside the chassis 60 is connected to the conveying component 52 of the screening device 50. When manual inspection of the plug-in quality and manual pressing are used, the conveying device 10 and the screening device 50 can play a direct role in conveying the PCB board.
[0061] The overall structure of the pressing component and AOI inspection equipment 100 is described below. For example... Figure 1 As shown, in one embodiment, the pressing and AOI inspection equipment 100 further includes a chassis 60, the conveying device 10, the pressing device 30 and the inspection device 20 are disposed inside the chassis 60, the screening device 50 is disposed on one side of the chassis 60, the chassis 60 has an input port 101 and an output port 102, the input port 101 corresponds to the input end of the conveying device 10, and the output port 102 corresponds to the output end of the conveying device 10.
[0062] This configuration allows the conveyor 10, pressing device 30, and inspection device 20 to be integrated into a single chassis 60. This enables the pressing and AOI inspection equipment 100 to perform component quality inspection and pressing operations during operation, eliminating the need for additional pre-furnace AOI inspection settings for component quality inspection before pressing, thereby saving floor space in the PCB board processing production line.
