[0029] A lateral strip 6 that is horizontally arranged and symmetrically distributed is fixed to both the left and right sides of the carrier plate 3. The rotating shaft of the servo motor 4 horizontally passes through one of the support plates 2 where it is located and is fixed to a lateral strip 6 on the same side.

[0030] Two calibration modules that are symmetrically distributed front and back are also provided between a support plate 2 on the same side and a lateral strip 6. The calibration module includes two guide sleeves 10 respectively embedded in the support plate 2 and the lateral strip 6, and a calibration cylinder 9 fixed to the outer wall of the support plate 2. The telescopic end of the calibration cylinder 9 is horizontally and movably inserted through the two guide sleeves 10.

[0031] A reinforcement module is also provided between the support plate 51 and the pressure plate 52. The reinforcement module includes a reinforcement cylinder 11 fixed to the top of the support plate 51 and on the same side as the slide table cylinder 55, and a pressing block 12 fixed to the telescopic end of the reinforcement cylinder 11. An inclined surface 121 that cooperates with the top edge of the adjacent side of the pressure plate 52 is formed at the lower corner of one side of the pressing block 12 facing the pressure plate 52.

[0032] A plurality of L-shaped pressing blocks 13 are also fixed to the bottom of the pressure plate 52.

[0036] Working principle:

[0037] Drive the telescopic end of the slide cylinder 55 in the clamping unit 5 to extend outwards or contract inwards, so as to drive the rack 56 and the stop block 511 to move to the right by means of the adapter block 59 and the adjusting block 510. Then, drive the clamping shaft 53 to rotate by means of the meshing connection relationship between the rack 56 and the gear 54, so as to drive the side of the pressing plate 52 away from the clamping shaft 53 to turn upwards. Then, place the switch board of the transporter flat on the top of the support plate 51, and make the end of each positioning post 57 insert into the corresponding concave hole located at the bottom of the switch board. Then, drive the telescopic end of the slide cylinder 55 to contract inwards or extend outwards to drive the pressing plate 52 to swing in the reverse direction in the same way until the end of each limit post 58 located at the bottom of the pressing plate 52 presses tightly on the top of the switch board. At this time, the end of each L-shaped pressing block 13 also presses tightly on the top of the switch board, thus completing the positioning and fixing of the switch board. Subsequently, drive the telescopic end of the reinforcement cylinder 11 in the reinforcement module to extend outwards to drive the extrusion block 12 to move towards the pressing plate 52 until the inclined surface 121 on the extrusion block 12 presses tightly on the top edge of the pressing plate 52 on the adjacent side, so as to firmly press down the pressing plate 52 to prevent the pressing plate 52 from bouncing upwards due to failure or accident. Finally, a drilling tool can be used to process the top of the switch board through the slot hole 521, the rectangular cavity hole 522 and the missing cavity 523. During the processing, the telescopic end of the calibration cylinder 9 in each calibration module extends into one of the corresponding guide sleeves 10 located in the side strip 6, so as to lock the two side strips 6 to prevent the carrier plate 3 from shaking during processing.

[0038] After the drilling step at the top of the switch board is completed, the telescopic ends of the calibration cylinders 9 in each calibration module are driven to contract inward so that the telescopic ends of each calibration cylinder 9 leave the guide sleeves 10 in the side bars 6; then the servo motor 4 is started to rotate its rotating shaft, and then the carrier plate 3 is driven to rotate 180 degrees by means of the two side bars 6, so that the switch board is driven to flip 180 degrees by means of the clamping unit 5; subsequently, the telescopic ends of the calibration cylinders 9 in each calibration module are driven to extend outward so that the telescopic ends of each calibration cylinder 9 are inserted into one of the corresponding guide sleeves 10 in the side bars 6, thus locking the two side bars 6 to prevent the carrier plate 3 from shaking during processing; then the drilling tool can be used to process the bottom of the switch board through one of the material-saving holes 31 and the L-shaped cavity hole 5101 below the material-saving hole 31.

[0039] After the processing is completed, the telescopic ends of the calibration cylinders 9 in each calibration module are driven to contract inward so that the telescopic ends of each calibration cylinder 9 leave the guide sleeves 10 in the side bars 6, and then the servo motor 4 is started to rotate its rotating shaft, and then the carrier plate 3 is driven to rotate 180 degrees in the reverse direction to reset in the same way; then, the telescopic end of the reinforcement cylinder 11 is driven to contract inward so that the inclined surface 121 on the extrusion block 12 leaves the pressing plate 52 in the same way, and then the telescopic end of the slide table cylinder 55 is driven to extend or contract outward so that the side of the pressing plate 52 away from the clamping shaft 53 is turned up upward in the same way, and finally the switch board can be taken out.

[0040] The utility model realizes the automatic positioning and pressing of the switch board, thereby improving the processing efficiency and simplifying the operation steps; moreover, it has the function of automatically flipping 180 degrees, so that the two sides of the switch board can be processed in turn without removing the switch board, thus saving the steps of repeatedly manually installing, removing and flipping the switch board, and further improving the processing efficiency to achieve the effect of saving time and effort.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
