This method makes it difficult to control the length and position of the glue coating, and the manual semi-automatic control has the problems of unstable efficiency and high labor cost. Therefore, a glue coating machine for PCB board processing is proposed. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown, the utility model provides a technical solution for a glue coating machine for PCB board processing: a glue coating machine for PCB board processing, comprising a plurality of mounting components 2, a glue coating component 3 arranged on the mounting components 2, and a driving component 1 for driving the mounting components 2, the mounting components 2 comprising four symmetrically arranged connecting platforms 21, a slide seat 22 arranged at both ends of each connecting platform 21, and a mounting platform 23 installed on the slide seat 22, the driving component 1 comprising a plurality of components arranged below the connecting platform 21 for driving the connecting platform 21, and the remaining components arranged in the connecting platform 21 for driving the slide seat 22 and the mounting platform 23;

[0021] Specifically, four connecting platforms 21 are arranged in groups of two, and the two groups of connecting platforms 21 are arranged on both sides, wherein several components for driving the connecting platforms 21 include a linear motor 11 respectively connected to each connecting platform 21, and a guide rail 12 respectively guiding each connecting platform 21, and components arranged in the connecting platform 21 include a driving motor 13 and a positive and negative threaded rod 14, the driving motor 13 drives the positive and negative threaded rod 14 to rotate, and the two slide seats 22 on a single connecting platform 21 are symmetrically connected to the two ends of the positive and negative threaded rod 14, and during the rotation of the positive and negative threaded rod 14, the two slide seats 22 on the single connecting platform 21 can be driven to move closer to or farther from each other, so as to adjust the position of the rubber-encapsulated component 3 on the installation component 2;

[0022] Furthermore, the rubber coating component 3 includes a driving device driving cylinder 31 and a servo motor 32, a wheel 33, a guide module 34 and a cutting module 35, wherein a rolled tape is installed on the wheel 33, the tape is guided by the guide module 34, and the tape is cut by the cutting module 35, and then the tape is wrapped on the PCB board;

[0023] The guide module 34 includes two guide wheels 344 arranged in an upper and lower position. Both guide wheels 344 are directly driven by the servo motor 32 through a synchronous belt, that is, the two guide wheels 344 rotate in the same direction. A fixed block 341 is arranged on one side of the guide wheel 344 close to the servo motor 32. A stopper 342 is elastically rotatably connected to the fixed block 341. A gas rod 343 is arranged on the other side of the guide wheel 344. The output end of the gas rod 343 passes through the upper guide wheel 344 and docks with the stopper 342.

[0024] The cutting module 35 includes a movable seat 351 driven by a driving cylinder 31, and two pressing wheels 354 are rotatably mounted on the movable seat 351. The two pressing wheels 354 are mounted up and down, wherein the pressing wheel 354 on the upper side is connected to the movable seat 351 through a rotating arm 353, and a pressing plate 352 is arranged on the movable seat 351 to press the rotating arm 353, and a cutting knife 355 is arranged at the end of the movable seat 351, and the cutting knife 355 is located directly above the stopper 342;

[0025] The stacked plates that have completed the nailing operation are transported to the rubber-wrapped area through the through-type conveying mechanism. There are two installation components 2 at each of the four corners of the stacked plates. At this time, the driving component 1 below works to drive the rubber-wrapped components 3 on each installation component 2 to gradually dock with the stacked plates to complete the rubber-wrapped. In this process, the positive and negative threaded rods 14 are parallel to the conveying direction. The four installation components 2 parallel to the conveying direction first dock with the stacked plates. The height of the stacked plates on the conveying mechanism is just above the guide module 34 and is located between the upper and lower pressure wheels 354. Refer to the following for the docking process. Figure 1The two drive motors 13 on the inner side rotate to drive the corresponding positive and negative screws 14 to rotate, so as to drive the four sets of slide seats 22 on the inner side to move closer to the middle of the stacked plate. After reaching the predetermined position, the servo motor 32 works to drive the upper and lower guide wheels 344 to rotate synchronously. Figure 4 It can be seen that the adhesive surface of the tape is in contact with the two sets of guide wheels 344, that is, the rotation of the guide wheels 344 can pull the tape out from the top of the stopper 342, and the length of the extended part is controlled by the rotation of the servo motor 32. After the extended length reaches the established requirement, the cylinder 31 is driven to work to drive the cutting module 35 to move toward the stacking plate, and the synchronous air rod 343 works, and its output end moves toward the direction of the tape to press the tape against the stopper 342, so that the cutting knife 355 can cut the tape when it moves. When cutting, the cut tape is at the edge of the corner of the stacking plate. With further movement of the cutting module 35, the stacking plate lifts up the rotating arm 353 and inserts it into the gap between the rotating arm 353 and the movable seat 351. During this process, the upper and lower pressing wheels 354 press against the cut tape and adhere the tape to the upper and lower surfaces at the edges of both sides. Then the driving cylinder 31 drives the cutting module 35 to withdraw from the stacking plate. After completing the rubber coating of this step, the driving motor 13 rotates in the opposite direction to control the installation component 2 and the rubber coating component 3 moved in the above steps to reset to the initial state and break away from the stacking plate. Then the remaining installation components 2 and rubber coating components 3 work.

[0026] The linear motor 11 works to control the two groups of connecting platforms 21 on the outside to move inward. Note that the drive motor 13 needs to control the corresponding installation components 2 and rubber-coated components 3 connected thereto to make way for the output of the remaining rubber-coated components 3. After the installation components 2 and rubber-coated components 3 on the outside move to the predetermined positions, the corresponding drive cylinder 31 and servo motor 32 output, which is the same as the output method mentioned above. After the servo motor 32 drives the guide module 34 to pull the tape out to a predetermined length, the drive cylinder 31 pushes the cutting module 35 to cut the tape, and the cut tape is guided by the cutting module 35 to be adhered to the upper and lower surfaces of the other two sides to complete the rubber coating. Then, the conveying mechanism conveys the laminated plate that has completed the rubber coating to the next mechanism.
