[0021] Example 1: Please refer to Figure 1-Figure 6A PCB gong device shown in the figure includes a fixed plate 1 fixedly installed on the gong machine control mechanism, and also includes a top plate 2 and a bottom plate 3 fixedly installed on the side of the fixed plate 1 away from the control mechanism, and the top plate 2 is located on the upper side of the bottom plate 3, and a plurality of connecting columns 4 distributed at equal distances are fixedly installed between the top plate 2 and the bottom plate 3; a gong mechanism is used to process the PCB board, and the number of gong mechanisms is two groups, and two gong mechanisms are installed on the outside of the top plate 2 and the bottom plate 3; a driving mechanism is used to drive the two gong mechanisms to rotate, and the driving mechanism is installed on the bottom plate 3; a lifting mechanism is used to adjust the height of the gong mechanism, and the lifting mechanism is installed on the outside of the gong mechanism.

[0022] The driving mechanism includes a driving motor 5 fixedly installed at the center of the upper end of the base plate 3, the lower end of the driving shaft of the driving motor 5 is fixedly connected to a disc 6, two symmetrically distributed connecting seats 7 are fixedly installed on the outer side of the disc 6, and the concentric angle between the two connecting seats 7 is 90°, and the gong plate mechanism includes a driving seat 8, and the outer side of the driving seat 8 is fixedly provided with a plurality of convex ribs 9 distributed equidistantly around the circumference, and the edges of the plurality of convex ribs 9 are all arc-shaped.

[0023] A positioning seat 10 is movably sleeved on the outer side of the driving seat 8 and the convex rib 9 near the lower end of the driving seat 8, and the connection between the positioning seat 10 and the connecting seat 7 is a fixed connection. A plug-in seat 11 is rotatably installed at the lower end of the driving seat 8, and a pin 12 is embedded in the center of the lower end of the plug-in seat 11. The connection between the pin 12 and the plug-in seat 11 is a plug-in connection. The cross-section of the pin 12 is rectangular and chamfered. A tool 13 is fixedly embedded in the center of the lower end of the pin 12.

[0024] A method for using a PCB gong board device: S1: Processing stage, the control mechanism on the gong machine drives the fixed plate 1 and the gong mechanism to move forward and backward, left and right, up and down to process the PCB board; S2: Tool changing stage, when the temperature of the tool 13 increases after processing the PCB board for a period of time, the driving motor 5 drives the two gong plate mechanisms to rotate, and the tool 13 is replaced, so that the two gong plate mechanisms are used alternately; S3: Ascending stage, during the replacement of the tool 13, the ball 24 at the lower end of the push rod 23 outside the replaced gong plate mechanism moves along the slope 1 of the arc stopper 1 25 to the highest point of the arc stopper 1 25, and the height of the replaced tool 13 moves upwards in the process; S4: During the tool 13 replacement stage, as the gong plate mechanism moves upward, multiple pins 14 will also move upward, and ball 18 moves upward to disengage from the positioning tube 19. At this time, a little force can be applied to disengage the hemispherical portion of the pin 14 from the hemispherical slot 17, making it easy to disassemble and assemble the pin column 12 and the socket 11, so that the tool 13 can be replaced.

[0025] Working principle: During the gong process of the PCB board, the control mechanism of the gong machine drives the fixed plate 1 and the two gong mechanisms to move forward and backward, left and right, and up and down, and the driving seat 8 on the processing station drives the tool 13 to rotate to process the PCB board. During the processing of the PCB board, due to the self-locking performance of the driving motor 5, the two gong mechanisms cannot rotate; after the tool 13 at the processing station processes the PCB board for a period of time, the driving motor 5 drives it to rotate in the corresponding direction according to the position of the gong mechanism on the processing station. At this time, the gong mechanism on the cooling station will be rotated to the processing station by the driving motor 5 to continue processing the PCB board, which is beneficial for the two gong mechanisms to alternately process the PCB board, thereby facilitating the alternate cooling of the tool 13, and effectively avoiding damage to the PCB board caused by overheating of the tool 13.

[0026] Example 2: Please refer to Figure 2-Figure 5 The present embodiment further explains the first embodiment, the lifting mechanism includes a sleeve seat 21 fixedly sleeved on the driving seat 8 and the outer side of the convex rib 9, and the sleeve seat 21 is located on the upper side of the positioning seat 10, a push rod 23 is installed directly behind the sleeve seat 21, and the push rod 23 is fixedly connected to the sleeve seat 21 through a fixed seat 22, and both ends of the push rod 23 are movably embedded with ball bearings 24, and the ball bearings 24 can reduce the movement resistance of the push rod 23, and two symmetrically distributed arc stoppers 25 are fixedly installed on the upper end of the bottom plate 3.

[0027] The two arc stops 25 are close to the edge of the bottom plate 3, and a slope 1 is provided at one end of the two arc stops 25 close to each other, and the ball 24 located at the lower end of the push rod 23 rolls with the arc stop 25 through the slope 1. A connecting column 4 located in the front is fixedly installed with an arc stop 26 on one side close to the gong plate mechanism, and slopes 2 are provided at both ends of the arc stop 26, and the ball 24 located at the upper end of the push rod 23 rolls with the arc stop 26 through the slope 2. The slope 2 can prevent the push rod 23 from being stuck by the arc stop 26.

[0028] The upper end of the socket 21 is fixedly connected with a spring 27, and the spring 27 is movably sleeved on the outer side of the driving seat 8. The spring 27 can drive the tool 13 to move downward. The upper end of the spring 27 is fixedly connected with a washer 28, and the washer 28 is movably sleeved on the outer side of the driving seat 8. The upper end of the washer 28 is installed with an arc stopper 29, and the arc stopper 29 is fixedly installed on the outer side of the top plate 2. The connection between the washer 28 and the top plate 2 and the arc stopper 29 is a sliding contact.

[0029] In this embodiment: when the driving motor 5 drives the gong plate mechanism on the processing station to rotate to the cooling station, the driving seat 8 will drive the ejector rod 23 to rotate together through the sleeve seat 21. During the rotation process, the ejector rod 23 rolls along the slope 1 of the arc stopper 1 25 through the ball 24 to the highest point of the arc stopper 1 25. During this process, the tool 13 in the gong plate mechanism will also rise to a certain height, which can effectively prevent the tool 13 on the processing station from affecting the movement of the tool 13 on the cooling station when the tool 13 on the processing station is processing the PCB board; When the gong plate mechanism on the processing station rotates to the cooling station, the gong plate mechanism on the cooling station will also rotate to the processing station. During the process of the gong plate mechanism on the cooling station rotating to the processing station, driven by the compression force of spring 27, the push rod 23 and the tool 13 will move down through the slope of the arc stopper 25. During the rotation of the push rod 23, the ball 24 at its upper end will roll and contact with it through the slope 2 of the arc stopper 26, so that the gong plate mechanism is completely moved down and reset. During the process of the gong plate mechanism processing the PCB board, the arc stopper 26 blocks the push rod 23 to prevent the gong plate mechanism from moving up.

[0030] Example 3: Please refer to Figure 6-Figure 8 This embodiment further explains Example 1. The outer side of the pin 12 is located inside the socket 11 and a plurality of connection components are installed in a circumferentially equidistant manner. The connection components include a pin rod 14 that can move inside the socket 11. The cross-sectional shape of the pin rod 14 is circular. A hemispherical portion is provided at one end of the pin rod 14 close to the pin 12. A washer 15 is fixedly sleeved on the outer side of the pin rod 14, and a spring 16 is movably sleeved on the outer side of the pin rod 14.

[0031] The two ends of the spring 16 are respectively in contact with the socket 11 and the washer 15, and the outer side of the pin 12 is provided with hemispherical slots 17, the number of which is equal to the connecting components, and the hemispherical part of the pin rod 14 is movably connected with the pin column 12 through the hemispherical slots 17, and a ball 18 is movably embedded at one end of the pin rod 14 away from the pin column 12, and the ball 18 can reduce the rotational resistance of the pin rod 14.

[0032] The outer side of the ball 18 is movably abutted against a positioning tube 19, and the positioning tube 19 is movably sleeved on the outer side of the socket 11. The connection between the ball 18 and the positioning tube 19 is rolling contact. The center of the positioning tube 19 coincides with the center of the socket 11. Two symmetrically distributed bent connecting rods 20 are fixedly installed on the outer side of the positioning tube 19, and the end of the bent connecting rod 20 away from the positioning tube 19 is fixedly connected to the positioning seat 10.

[0033] In this embodiment, during the upward movement of the gong plate mechanism, the plurality of positioning components move upward accordingly. After the ball 18 in the positioning component moves upward and disengages from the positioning tube 19, the pin 14 can move inside the socket 11. At this time, a little force can be applied to disengage the hemispherical portion of the pin 14 from the hemispherical slot 17, thereby facilitating the disassembly and assembly between the pin 12 and the socket 11. When the gong mechanism moves down and resets, during the process of the tool 13 rotating to process the PCB board, multiple ball bearings 18 roll against the inner wall of the positioning tube 19, and the positioning tube 19 can block the pin rod 14 from moving inside the socket 11 through the ball bearings 18, so that during the process of the tool 13 processing the PCB board, the pin column 12 and the socket 11 are firmly connected, and the tool 13 will not fall.
