[0077] An embodiment of the present invention provides a position calibration device, such as Figure 1-Figure 3 As shown, the position calibration device includes a first bracket 1, a second bracket 2, a reference member 3 and a position calibration mechanism 4; the first bracket 1 and the second bracket 2 are arranged opposite to each other and spaced apart; the reference member 3 is installed on the first bracket 1 along a first direction, and the reference member 3 cooperates with the first bracket 1 to form a reference position for limiting the adjacent two side edges of the plate;

[0078] The position calibration mechanism 4 is movably mounted on the second bracket 2 along the second direction and the first direction, and is used to limit the other two adjacent edges of the plate, where the first direction and the second direction intersect.

[0079] As an example, a first bracket 1 and a second bracket 2 are positioned opposite each other to form two mounting datums. One end of a datum member 3 is mounted on the first bracket 1 along a first direction. The datum member 3 is perpendicular to the first bracket 1, so that the datum member 3 and the first bracket 1 cooperate to form a datum position, which is used to position adjacent edges of a sheet material. Specifically, the adjacent edges of the sheet material are controlled to abut against the datum member 3 and the first bracket 1, respectively, so that the datum member 3 and the first bracket 1 can compress the adjacent edges of the sheet material. A position calibration mechanism 4 is mounted on the second bracket 2 movably along a second direction and the first direction. It is used to position the other adjacent edges of the sheet material. Specifically, the position calibration mechanism 4 is controlled to abut against the other adjacent edges of the sheet material so that the position calibration mechanism 4 can compress the other adjacent edges of the sheet material. In this example, the position calibration mechanism 4 can be controlled to move in the second direction based on the length of the sheet material, and / or can be controlled to move in the first direction based on the width of the sheet material, so that the position calibration mechanism 4 compresses the other adjacent edges of the sheet material in both directions. The sheet material here can be a PCB or other sheet material requiring processing. The first direction and the second direction intersect, and the intersection angle between the two can be 90 degrees or other angles.

[0080] In this example, the adjacent two side edges of the plate are first limited based on the reference position formed by the reference part 3 and the first bracket 1; then, according to the length and width of the plate, the position calibration mechanism 4 is moved along the second direction and the first direction, and its position on the second bracket 2 is adjusted, so that the position calibration mechanism 4 can squeeze the other adjacent two side edges of the plate in two directions, so that the position calibration device abuts against the four side edges of the plate, thereby ensuring the accuracy of the position calibration; since the position calibration mechanism 4 can move along the second direction and the first direction, it can limit plates of different sizes, is not limited by the size and position of the plate, and has better applicability; and the overall structure is simple, does not require an additional camera system, and has a low cost.

[0081] In one embodiment, if Figure 1-Figure 3 As shown, the position calibration mechanism 4 includes a moving component 41 and two hitting plate components 42; the moving component 41 is movably mounted on the second bracket 2 along the second direction and the first direction; the two hitting plate components 42 are mounted on the moving component 41, one hitting plate component 42 is arranged opposite to the reference part 3, and the other hitting plate component 42 is arranged opposite to the first bracket 1.

[0082] The plate-beating assembly 42 is a component used to squeeze the plate to achieve position calibration, and the moving assembly 41 is a component used to control the movement of the plate-beating assembly 42 .

[0083] As an example, the position calibration mechanism 4 includes a moving assembly 41 and two striking assemblies 42. The two striking assemblies 42 are mounted on the moving assembly 41 so that the moving assembly 41 can drive the two striking assemblies 42 to move in the second direction and the first direction. The moving assembly 41 is movably mounted on the second bracket 2 in both the second and first directions. Specifically, the moving assembly 41 can be controlled to move in the second direction based on the length of the plate and / or in the first direction based on the width of the plate, thereby adjusting the positions of the two striking assemblies 42 according to the size of the plate. One of the two striking assemblies 42 is positioned opposite the reference member 3. The relative distance between the two striking assemblies 42 is determined by the length of the plate (i.e., the position of the moving assembly 41 in the second direction), allowing the striking assembly 42 to compress the edge of the plate opposite the reference member 3. The other striking assembly 42 is positioned opposite the first bracket 1. The relative distance between the two striking assemblies 42 is determined by the width of the plate (i.e., the position of the moving assembly 41 in the first direction), allowing the striking assembly 42 to compress the edge of the plate opposite the first bracket 1. In this example, the moving component 41 drives the two plate-beating components 42 to move along the second direction and the first direction, so that the two plate-beating components 42 squeeze the other adjacent two side edges of the plate away from the reference position, thereby achieving the limitation of plates of different sizes.

[0098] As an example, the first connecting member 413 includes a first main body portion 4132 arranged along a first direction and two first limiting portions 4133 extending from both ends of the first main body portion 4132 along a third direction. The first main body portion 4132 and the two first limiting portions 4133 cooperate to form a first groove for accommodating the second bracket 2 so that the first connecting member 413 can be movably arranged on the second bracket 2 along the second direction.

[0099] As an example, the second connecting member 414 includes a second main body 4143 arranged along the first direction, two second limiting portions 4144 extending from both ends of the second main body 4143 along the first direction in a third direction, and two third limiting portions 4145 extending from both side edges of the second main body 4143 along the second direction in the third direction. The second limiting portions 4144 and the third limiting portions 4145 extend in opposite directions.

The second main body 4143 and the two third limiting portions 4145 cooperate to form a guide groove 4141 arranged along the first direction. The guide groove 4141 is used to install the first support rod 411 or the second support rod 412, so that the first support rod 411 or the second support rod 412 can move along the guide groove 4141, providing installation guidance for the corresponding support rod.

[0100] In this example, the first connecting member 413 is provided with a first through hole 4131 that cooperates with the fastening component 6, specifically, the first through hole 4131 is provided on the first main body 4132; the second connecting member 414 is provided with a second through hole 4142 that cooperates with the fastening component 6, specifically, the second through hole 4142 is provided on the second main body 4143. The fastening component 6 can be used to fix the support rod, the second connecting member 414, the first connecting member 413 and the second bracket 2.

[0101] In one embodiment, if Figure 3 As shown, the plate-beating assembly 42 includes a telescopic member 421 and a buffer member 422. The telescopic member 421 is installed on the moving assembly 41. The output end of the telescopic member 421 is connected to the buffer member 422. The buffer member 422 is arranged opposite to the reference member 3 or the first bracket 1 and is used to squeeze one side edge of the plate.

[0102] As an example, the plate-beating assembly 42 includes a telescopic member 421, which is mounted on the moving assembly 41, specifically on the first support rod 411, the second support rod 412 or the third support rod, and can move along the second direction and the first direction under the drive of the corresponding support rod. The output end of the telescopic member 421 is connected to the buffer member 422, and the buffer member 422 is arranged opposite to the reference member 3, and is used to squeeze the plate away from one side edge of the reference member 3; or, the buffer member 422 is arranged opposite to the first bracket 1, and is used to squeeze the plate away from one side edge of the first bracket 1. In this example, the output end of the telescopic member 421 can reciprocate along its axial direction to adaptively adjust according to the size of the plate and squeeze one side edge of the plate. In this example, the buffer 422 can be a soft rubber or other elastic structural member. One side of the buffer 422 is connected to the output end of the telescopic member 421, and the other side of the buffer 422 is used to abut against one side edge of the plate, so as to squeeze one side edge of the plate under the drive of the telescopic member 421. The buffer 422 helps to reduce the force of the telescopic member 421 acting on the plate, thereby avoiding damage to the plate during the extrusion process.

[0103] In one embodiment, if Figure 3 As shown, the plate-beating assembly 42 also includes a transition piece 423, which is arranged on the output end of the telescopic piece 421, and there is a buffer gap between the transition piece 423 and the side of the output end of the telescopic piece 421 close to the plate; the buffer piece 422 is arranged on the transition piece 423; the telescopic piece 421 includes a pneumatic cylinder, an electric cylinder or a hydraulic cylinder.

[0104] As an example, the plate-beating assembly 42 also includes a transition piece 423, which is arranged on the output end of the telescopic piece 421. A buffer gap is formed between the transition piece 423 and the side of the output end of the telescopic piece 421 close to the plate. The buffer piece 422 is arranged on the transition piece 423. When the output end of the telescopic piece 421 moves in the axial direction and squeezes one side edge of the plate, the plate will provide a reverse force. Since there is a buffer gap between the transition piece 423 and the output end of the telescopic piece 421, the reverse force can be absorbed by the deformation of the transition piece 423, thereby avoiding damage to the output end of the telescopic piece 421 during the extrusion process.

[0105] As an example, transition piece 423 can be an L-shaped transition piece, comprising a first component and a second component perpendicular to each other. The first component is detachably connected to the output end of telescopic member 421 via bolts, and the second component is positioned opposite the output end of telescopic member 421, closer to the plate, with a buffer gap between them. Buffer member 422 is positioned on the second component. It is understood that transition piece 423 can also be a U-shaped transition piece or other shapes, and its shape can be selected based on actual conditions.

[0106] As an example, the telescopic member 421 may be any one of a pneumatic cylinder, an electric cylinder or a hydraulic cylinder, preferably a pneumatic cylinder, which has lower cost.

[0108] As an example, the first bracket 1 includes a first slot 11 arranged along the second direction; a slider 31 is provided at one end of the reference member 3. The slider 31 is integrally formed with the reference member 3, or the slider 31 and the reference member 3 are fixed to form a one-piece structure by welding or other means. In this example, the slider 31 is provided at one end of the reference member 3 and is movably mounted within the first slot 11. When the slider 31 is adjusted to a suitable position in the first slot 11, a first bolt can be inserted into the threaded hole 32 and tightened to secure the reference member 3 to the first bracket 1.

[0109] In this example, when coding or performing other processing on the plate, it is necessary to ensure that the center position of the plate is aligned with the center of the material table of the processing equipment. At this time, it is necessary to control the reference member 3 to move to a suitable position along the second direction according to the width of the plate, so that the reference position formed by the reference member 3 and the first bracket 1 can limit the adjacent two side edges of the plate.
