[0033] It should be noted that in the current electronic manufacturing industry, circuit boards are the basic components of electronic devices, and their size is directly related to subsequent assembly, connection, and the performance and reliability of the overall equipment. The existing circuit board size detection method mainly relies on manual operation. Technicians use special measuring tools to measure the size of the circuit board. The detection operation is not only time-consuming and laborious, but also the accuracy of the detection results cannot be guaranteed, which will affect the subsequent production of the circuit board.

[0034] like Figure 1-Figure 4As shown, this embodiment provides a fully automatic center positioning measurement device, in which the lateral push plate 21 pushes the circuit board to move horizontally, and the longitudinal push block 31 pushes the circuit board to move longitudinally. Under the joint action of the lateral push plate 21 and the longitudinal push block 31, it is ensured that the circuit board can be automatically straightened, and high-precision positioning of the circuit board is achieved, thereby accurately measuring the lateral and longitudinal dimensions of the circuit board, and providing accurate data support for subsequent circuit board production.

[0035] Specifically, it includes a frame 10, a transverse distance measuring mechanism 20 and a longitudinal distance measuring mechanism 30. The frame 10 is provided with conveying rollers 11 arranged in an array. The conveying rollers 11 are used to carry and convey the circuit board so that it can move smoothly during the measurement process.

[0036] The transverse distance measuring mechanism 20 is arranged on the frame 10, and the transverse distance measuring mechanism 20 includes a transverse push plate 21 and a transverse driving module 22. The transverse push plate 21 is connected to the transverse driving module 22. The transverse push plate 21 is used to push the circuit board to move transversely on the conveying roller 11, and the transverse driving module 22 is used to drive the transverse push plate 21 to move transversely and measure the distance moved by the transverse push plate 21 at the same time.

[0037] The longitudinal distance measuring mechanism 30 is arranged on the frame 10, and includes a longitudinal push block 31, a lifting mechanism 32 and a longitudinal driving module 33. The longitudinal push block 31 is connected to the lifting mechanism 32, and is used to drive the longitudinal push block 31 to move up and down. Through the adjustment of the lifting mechanism 32, it can be ensured that the longitudinal push block 31 will not prevent the circuit board from being transported to the conveying roller 11 of the frame 10, and it can be ensured that the longitudinal push block 31 can maintain appropriate contact force and position when pushing the circuit board. The longitudinal push block 31 is also connected to the longitudinal driving module 33, and the longitudinal push block 31 is used to push the circuit board to move longitudinally on the conveying roller 11. The longitudinal driving module 33 is used to drive the longitudinal push block 31 to move longitudinally, and at the same time measure the distance moved by the longitudinal push block 31.

[0038] Specifically, the output roller 11 is discontinuous, and a gap is reserved for the clamping plate to clamp the circuit board.

[0039] In one embodiment, the transverse driving module 22 is located below the conveying roller 11, the transverse push plate 21 is located above the conveying roller 11, and the transverse push plate 21 is connected to the transverse driving module 22 through a connecting unit 23, and the connecting unit 23 also moves along the transverse track 12 arranged on the frame 10. The connecting unit 23 not only plays a role in transmitting power, but also enables the transverse push plate 21 to move smoothly along the transverse track 12 arranged on the frame 10. Specifically, the initial position of the transverse push plate 21 is close to the first side of the frame 10. Driven by the transverse driving module 22, the connecting unit 23 moves along the transverse track 12, driving the transverse push plate 21 to move from the first side of the frame 10 to the second side of the frame 10.

[0040] In this embodiment, the lateral drive module 22 includes a lateral servo motor 221 and a lateral adjustment belt 222. The lateral servo motor 221 is connected to the lateral adjustment belt 222, and the lateral adjustment belt 222 is connected to the connecting unit 23, so that the lateral servo motor 221 drives the lateral push plate 21 on the connecting unit 23 to move laterally through the lateral adjustment belt 222.

[0041] Specifically, the output end of the transverse servo motor 221 is connected to the transverse driving wheel 223, and the transverse driving wheel 223 is connected to the transverse driven wheel 224 through the transverse adjustment belt 222, thereby forming a complete transverse drive module 22. When the transverse servo motor 221 is started, it will drive the transverse driving wheel 223 to rotate, and then transmit power to the transverse driven wheel 224 through the transverse adjustment belt 222. In this way, a complete drive chain is formed, which can stably and accurately push the connecting unit 23 and the transverse push plate 21 to move along the transverse track 12.

[0042] In this embodiment, a lateral control module is also included, which is connected to the lateral servo motor 221. The encoder of the lateral servo motor 221 obtains the rotation number information of the lateral servo motor 221 and transmits this rotation number information to the lateral control module for accurately calculating the distance moved by the lateral push plate 21, thereby realizing accurate measurement of the lateral size of the circuit board.

[0043] In one embodiment, the longitudinal distance measuring mechanism 30 is arranged in the middle of the frame 10, and the surface of the longitudinal distance measuring mechanism 30 is lower than the surface of the conveying roller 11. The purpose of the setting is to ensure that the overall setting of the longitudinal distance measuring mechanism 30 will not affect the circuit board being input to the conveying roller 11 of the frame 10.

[0044] The longitudinal distance measuring mechanism 30 includes a longitudinal servo motor 331 and a longitudinal adjustment belt 332 , which are connected so that the longitudinal servo motor 331 drives the longitudinal push block 31 to move along the longitudinal track 13 arranged on the frame 10 through the longitudinal adjustment belt 332 .

[0045] Specifically, the output end of the longitudinal servo motor 331 is connected to the longitudinal driving wheel 333, and the longitudinal driving wheel 333 is connected to the longitudinal driven wheel 334 through the longitudinal adjustment belt 332, thereby forming a complete longitudinal drive module 33. When the longitudinal servo motor 331 is started, it will drive the longitudinal driving wheel 333 to rotate, and then transmit power to the longitudinal driven wheel 334 through the longitudinal adjustment belt 332. In this way, a complete drive chain is formed, which can stably and accurately push the longitudinal push block 31 to move along the longitudinal track 13.

[0046] In this embodiment, the lifting mechanism 32 is a lifting cylinder, the output end of which is connected to the longitudinal push block 31, and the lifting cylinder is connected to the slider 35 on the longitudinal track 13 through the mounting plate 34. By adjusting the lifting cylinder, it can be ensured that the longitudinal push block 31 does not prevent the circuit board from being transported to the conveying roller 11 of the frame 10, and it can be ensured that the longitudinal push block 31 can maintain appropriate contact force and position when pushing the circuit board.

[0047] In this embodiment, a longitudinal control module is also included, and the longitudinal control module is connected to the longitudinal servo motor 331. The encoder of the longitudinal servo motor 331 obtains the rotation number information of the longitudinal servo motor 331, and transmits this rotation number information to the longitudinal control module for accurately calculating the distance moved by the longitudinal push block 31, thereby realizing accurate measurement of the lateral size of the circuit board.

[0052] Specifically, the frame 10 has an opposite head end and a tail end, and the total length of the head end and the tail end minus the thickness of the longitudinal push block 31 is obtained to obtain the longitudinal length c1 of the preset frame 10. The frame 10 also has an opposite first side and a second side, and the total length of the first side and the second side minus the thickness of the transverse push plate 21 is obtained to obtain the transverse length d1 of the preset frame 10.

[0053] The longitudinal driving module 33 drives the longitudinal push block 31 to move the circuit board longitudinally to the rear end of the rack 10, and records the longitudinal motion track length c2 of the longitudinal push block 31.

[0060] The lateral driving module 22 drives the lateral push plate 21 to move lateral from the first side of the frame 10 to the second side of the frame 10 , driving the circuit board to move lateral to contact with the second side of the frame 10 ;

[0061] At the same time, the lifting mechanism 32 drives the longitudinal push block 31 to move upward and extend out of the surface of the conveying roller 11, and the longitudinal driving module 33 drives the longitudinal push block 31 to move longitudinally toward the rear end of the frame 10, pushing the circuit board to move longitudinally until it contacts the rear end of the frame 10;

[0062] The transverse servo motor 221 transmits the rotation number information obtained to the transverse control module, and calculates the motion track length d2 of the transverse push plate 21; the longitudinal servo motor 331 transmits the rotation number information obtained to the longitudinal control module, and obtains the motion track length c2 of the longitudinal push block 31;
