That is, the corresponding electronic components are placed on a universal substrate according to a predetermined design by welding and other methods, and the electrical connections between the electronic components are made through copper lines. As an important component in electronic engineering, it improves the quality and reliability of electronic equipment. In the process of PCB board processing, sealing is an indispensable step. Through the sealing and dispensing operation, a reliable protective layer is formed to increase the mechanical strength of the PCB board, effectively prevent the solder joints from loosening, and play a role in moisture-proof, corrosion-resistant and insulating the PCB board and its electronic components.

[0003] After searching for the invention patent with patent number CN109847994B, an automatic dispensing device for PCB boards of electronic devices is disclosed. The driving motor drives the output shaft to rotate, thereby driving the driven shaft to rotate.

When the square frame frame 16 is completely engaged in the frame cavity of the assembly frame 11, the elastic deformation of the third spring 18 is used to reset, drive the second positioning pin 17 to reset and slide on the frame wall of the assembly frame 11, and the hemispherical nail head of the second positioning pin 17 is engaged and connected with the frame body of the square frame frame 16, and the square frame frame 16 is limited and locked, so that the adjustable clamping assembly 4 is fixedly placed on the assembly frame 11; When the PCB board dispensing device is used, the self-turning intermittent transport mechanism 3 is placed in a horizontal state, and can perform intermittent transport at 90 degrees, transport the adjustable clamping component 4 to the front, and perform the dispensing operation on one side of the PCB board through the dispensing device body 1. When the self-turning intermittent transport mechanism 3 continues to intermittently transport, the adjustable clamping component 4 is transported to the left, and the automatic face-changing of the adjustable clamping component 4 is completed, and the dispensing operation on the other side of the PCB board is performed through the dispensing device body 1; Specifically, according to the attached Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the self-turning intermittent transport mechanism 3 is fixedly mounted on the column frame 2. After the column frame 2 is mounted, it is fixedly connected to the upper side of the cabinet of the glue dispenser body 1 by bolts, and is arranged in a vertically upward state. Since the motor assembly 9 is composed of a servo motor body and a motor frame, in which the servo motor body is fixedly mounted on the motor frame by bolts, and is arranged in a vertically upward state, after the motor assembly 9 is mounted, the motor frame is sleeved and fixedly connected to the lower section of the column frame 2 by bolts. Since the driving gear 8 is sleeved and fixedly connected to the output end of the servo motor body in the motor assembly 9 by bolts after being mounted, the intermittent operation of the motor assembly 9 is started, and the driving gear 8 is driven to rotate intermittently; Since an integrated pipe frame portion is provided directly below the ring disc frame 6, the driven gear ring 7 is placed and sleeved and fixedly connected to the outside of the pipe frame portion in the ring disc frame 6 by bolts, and it and the ring disc frame 6 form a synchronous rotation structure. Since the right side of the driven gear ring 7 is meshed and connected with the driving gear 8, when the driving gear 8 is driven to rotate intermittently, the driven gear ring 7 is driven to rotate intermittently through the meshing action between the driven gear ring 7 and the driving gear 8, and the ring disc frame 6 is driven to move intermittently; Since the center of the tube frame part of the ring-disc frame 6 and its center are on the same vertical central axis, and bearings are installed at the upper and lower ends of the tube openings of the tube frame part, and since the tube frame part and the bearings are movably sleeved on the middle section of the column frame 2 after the ring-disc frame 6 is installed, the tube frame part of the ring-disc frame 6 is driven to rotate on the column frame 2 with the assistance of the bearings, thus completing the intermittent rotation of the self-turning intermittent transport mechanism 3 on the column frame 2; When the intermittent transfer mechanism 3 is intermittently transferred, the adjustable clamping assembly 4 is transported to the front. At this time, the pin portion in the push block 14 is still placed in the first arc groove 1001, that is, the assembly frame 11 is not driven and does not perform the flipping operation. Since the glue dispenser body 1 is an existing three-axis glue dispenser (which is a prior art and is not described in detail in the drawings of the specification), the three axial movements of the X-axis, Y-axis and Z-axis are controlled to perform precise glue dispensing operations. Since the frame cavity width of the square frame frame 16 is equal to the frame cavity width of the assembly frame 11, the glue dispensing operation on one side of the PCB board is completed through the glue dispenser body 1; Since the linkage disk 10 is in a horizontal state after being placed, it is sleeved and fixedly connected to the upper end of the pedestal frame 2 by bolts, and is placed in the annular cavity of the ring disk frame 6, and its center coincides with the center of the ring disk frame 6. Since the first arc groove 1001 is opened on the right side of the disk body of the linkage disk 10, its arc center coincides with the center of the linkage disk 10, and the second arc groove 1002 is opened on the left side of the disk body of the linkage disk 10, its arc center coincides with the center of the linkage disk 10, and the first and tail ends of the first arc groove 1001 are respectively coincident with the second arc groove 1002. The tail and head ends of the arc groove 1002 are connected to form an annular groove. Since the end of the narrow portion of the push block 14 is threadedly fixed with a vertical pin, the first arc groove 1001 and the second arc groove 1002 are connected to the pin in the push block 14 in a sliding manner. When the self-turning intermittent transport mechanism 3 is intermittently transported, the adjustable clamping assembly 4 is transported to the left. At this time, the pin in the push block 14 slides into the second arc groove 1002 through the first arc groove 1001; Since the radius of the first arc groove 1001 is smaller than the radius of the second arc groove 1002, the distance difference between the radius of the first arc groove 1001 and the radius of the second arc groove 1002 is equal to the maximum sliding dimension of the push block 14. When the pin portion of the push block 14 slides into the second arc groove 1002, the push block 14 is pushed. Since the cross section of the push block 14 is in a "convex" shape, the longitudinal sections of the wide part and the narrow part are both in a square structure, and since the push block 14 is movably clamped in the groove wall of the ring disc frame 6 after being placed, the narrow part movably penetrates the groove wall of the ring disc frame 6 and extends into the ring cavity thereof, and is positioned on the ring disc frame 6 in an active state, the push block 14 slides and contracts on the ring disc frame 6 after being pushed; Since the assembly frame 11 is arranged in a "U"-shaped structure, the middle part of the horizontal frame is fixedly connected with a cylindrical part in a vertical state by bolts, and since the wide part of the push block 14 is movably sleeved on the cylindrical part of the assembly frame 11 after being arranged, a second spring 15 is installed at the connection between the push block 14 and the cylindrical part of the assembly frame 11, and the second spring 15 is movably inserted into the groove cavity of the cylindrical part of the assembly frame 11 after being arranged, one end of the second spring 15 is pressed against the groove cavity wall of the cylindrical part of the assembly frame 11, and the other end of the second spring 15 is pressed against the groove wall of the push block 14, and after being pushed, the push block 14 slides on the cylindrical part of the assembly frame 11, and the second spring 15 is squeezed and elastically deformed; Since the first spiral groove 1101 is provided on the cylindrical portion of the assembly frame 11, two of them are arranged in a circular array with the center of the cylindrical portion of the assembly frame 11 as the center of the circle, and the spiral angle is 180 degrees, and since the first pin 1401 is threadedly fixed to the wide portion of the push block 14, it is symmetrically arranged about the horizontal center axis of the push block 14, and the first pin 1401 is arranged in a vertical state after being arranged, and is inserted in the first spiral groove 1101 in an active state, after the push block 14 slides, the first pin 1401 slides in the first spiral groove 1101, and the cylindrical portion of the assembly frame 11 is driven to move through the cooperation between the first pin 1401 and the first spiral groove 1101; Since the disk body of the ring disk frame 6 is provided with four empty grooves in a circular array with its center as the center, the cylindrical part in the assembly frame 11 is combined with its frame body to form an integrated structure, wherein bearings are installed at both ends of the cylindrical part, and after being placed, the cylindrical part is movably clamped in the hollow groove of the ring disk frame 6, wherein the cylindrical part together with the bearing is movably inserted on the groove wall of the hollow groove of the ring disk frame 6, and after the cylindrical part in the assembly frame 11 is driven, the assembly frame 11 is turned over in the hollow groove of the ring disk frame 6 with the assistance of the bearing, that is, the assembly frame 11 drives the adjustable clamping assembly 4 to perform a turning operation; Since a first positioning pin 12 for limiting is arranged at the connection between the cylindrical part of the assembly frame 11 and the empty groove wall of the ring disc frame 6, the first positioning pin 12 is arranged in a pin-shaped structure, wherein the nail head part is a hemispherical structure, and it is symmetrically arranged about the horizontal center axis of the assembly frame 11, and the first positioning pin 12 is movably clamped in the groove wall of the ring disc frame 6 after being installed, and since a first spring 13 is installed at the connection between the first positioning pin 12 and the ring disc frame 6, the first spring 13 is movably inserted in the groove wall of the ring disc frame 6 after being installed, and one end of the first spring 13 presses on the nail tail of the first positioning pin 12, and the other end of the first spring 13 presses on the nail tail of the first positioning pin 12, and the other end of the first spring 13 presses on the nail tail of the first positioning pin 12. One end is pressed against the end cover (the end cover is threadedly fixed on the groove wall of the ring disc frame 6). When the assembly frame 11 is turned over, the cylindrical part and the hemispherical end nail head of the first positioning pin 12 lose the engagement connection, so that the first positioning pin 12 is pushed on the groove wall of the ring disc frame 6 to slide and shrink, and the first spring 13 is squeezed and elastically deformed. When the assembly frame 11 is turned over and the face is changed, the elastic deformation of the first spring 13 is used to reset, so that the hemispherical end nail head of the first positioning pin 12 is engaged and connected with the cylindrical part of the assembly frame 11, and the assembly frame 11 after the face is turned over is limited and locked; When the PCB board dispensing device is used, a self-pick-and-place conveying mechanism 5 is arranged directly behind the self-turning intermittent transfer mechanism 3. The self-pick-and-place conveying mechanism 5 located directly behind is used for the automatic picking and unloading operation of the adjustable clamping assembly 4. Specifically, according to the above, the adjustable clamping assembly 4 is arranged in a detachable structural state on the self-turning intermittent transfer mechanism 3. The movable frame 29 is moved to the corresponding adjustable clamping assembly 4 through the extension operation of the electric push rod 30, and the corresponding adjustable clamping assembly 4 is clamped and locked by two electromagnetic clamps 31. Then, the electric push rod 30 is retracted and operated to make the movable frame 29 drive the corresponding adjustable clamping assembly 4 to detach from the assembly frame 11, and move to the conveyor belt 28 to complete the delivery; In order to better demonstrate the specific working process of the PCB board dispensing device, a PCB board dispensing device and a dispensing method thereof are provided in the present embodiment, and the dispensing method comprises the following steps: first, the PCB board is placed in the adjustable clamping assembly 4 to form a standard part, and then the adjustable clamping assembly 4 is conveyed to the self-flipping intermittent transfer mechanism 3 through the self-pick-and-place conveying mechanism 5 directly to the right of the self-flipping intermittent transfer mechanism 3 for loading, and then the adjustable clamping assembly 4 is transported to the front through the intermittent rotation of the self-flipping intermittent transfer mechanism 3, and the dispensing operation on one side of the PCB board is performed through the dispensing device body 1, and then the adjustable clamping assembly 4 is transported to the left through the intermittent rotation of the self-flipping intermittent transfer mechanism 3, after the face change of the adjustable clamping assembly 4 is completed, and the dispensing operation on the other side of the PCB board is performed through the dispensing device body 1, and finally the adjustable clamping assembly 4 is withdrawn to the self-flipping intermittent transfer mechanism 3 through the self-pick-and-place conveying mechanism 5 directly behind the self-flipping intermittent transfer mechanism 3 for unloading; This is the entire working process of the PCB board dispensing device and the dispensing method thereof.
