Description

Technical Field

[0001] The utility model belongs to the technical field of PCB positioning, and particularly relates to a blanking plate positioning device and a PCB processing device. Background Art

[0002] Before laser processing of a PCB, a manipulator grabs the stacked semi-finished PCBs in a magazine to a main machine platform. Regardless of the size of the PCB, the center point is used as the positioning origin, and multiple PCBs are stacked and centered in the magazine.

[0003] However, the current PCB processing device cannot achieve the center positioning of the PCB on the main machine platform. Before placing the semi-finished PCB on the main machine platform, it is necessary to perform positioning on a positioning device to align the PCB to the lower left corner, so as to facilitate the CCD to find the target holes within a predetermined coordinate range for precise positioning.

[0004] The positioning process of the existing positioning device is as follows: The manipulator places the PCB on a moving plate surface, and drives the moving plate surface to move towards the lower left corner through an inclined cylinder. After the positioning cylinder completes the positioning, the manipulator takes away the PCB. Due to the limited movement stroke of the inclined cylinder, especially for small-sized PCBs, multiple positioning processes are required to meet the positioning requirements. After each positioning is completed, the manipulator grabs the PCB. After the inclined cylinder and the positioning cylinder are reset, the PCB is placed again. At this time, the PCB has left the center position, and then the positioning process is repeated multiple times to gradually align the PCB to the lower left corner. The positioning process is cumbersome and the positioning efficiency is low. Summary of the Utility Model

[0043] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0044] As Figures 1 to 4 shown, a material plate positioning device provided by an embodiment of the present utility model includes a carrier plate 1, a driving unit and a plurality of rolling components 4. The plurality of rolling components 4 are arranged at intervals in sequence along the first direction a, and both ends of the plurality of rolling components 4 are respectively rotatably connected to opposite sides of the carrier plate 1.

[0045] The carrier plate 1 has a first position and a second position. The driving unit can drive the plurality of rolling components 4 to rotate, so as to drive the material plate placed on the rolling components 4 to move along the first direction a to the first position and move from the first position to the second position along the second direction b, realizing the positioning of the material plate on the positioning device.

[0046] Wherein, the first direction a and the second direction b are not parallel and do not coincide.

[0047] In this embodiment, the driving unit can drive all the rolling components 4 to rotate. After the material plate is placed on the rolling components 4, the material plate can move along with the rotation of the rolling components 4. The material plate has two strokes. The first stroke is that the rolling components 4 drive the material plate to move from its starting position to the first position. After moving to the first position, the material plate and the carrier plate 1 remain relatively stationary in the first direction. Then the rolling components 4 drive the material plate to move from the first position to the second position along the second direction, completing the second stroke and realizing the positioning of the material plate on the carrier plate 1.

[0048] During the positioning process of the material board, the material board can achieve positioning at any position on the carrier board 1 through two strokes in the first direction a and the second direction b. The positioning process is simple, and the material board is driven by the rolling component 4, eliminating the need for repeated processes of moving and grasping the material board, and also eliminating the need for a manipulator to cooperate in picking up and putting down. This can improve the positioning efficiency and achieve rapid positioning of material boards of various widths.

[0049] In one embodiment, as Figure 1 shown, the material board is a PCB, the first direction a and the second direction b are perpendicular, the first direction is the Y direction, and the second direction is the X direction. The manipulator places the PCB at the center position of the carrier board 1. By driving the rolling component 4 to rotate through the driving unit, the PCB can move from the center position of the carrier board 1 along the Y direction to the first position of the carrier board 1, and then move from the first position to the second position to achieve the positioning of the PCB. Among them, the second position is the lower left corner of the carrier board 1. The manipulator grabs the PCB at the lower left corner and transfers the PCB to the PCB processing equipment.

[0050] In one embodiment, the driving unit includes a driving component 2 and an annular transmission member 3. The driving component 2 is installed on the carrier board 1. The driving component 2 is connected to one end of a rolling component 4 to drive the rolling component 4 to rotate. The annular transmission member 3 is in transmission connection with the other ends of multiple rolling components 4. When the rolling component 4 connected to the driving component 2 rotates, it can drive the remaining rolling components 4 to rotate through the annular transmission member 3, so that multiple rolling components 4 rotate synchronously, realizing the moving and positioning of the rolling components 4 for the material board.

[0051] In one embodiment, as Figure 1 、 Figure 2 shown, the driving component 2 includes a motor 21 and a synchronous belt assembly 22. The synchronous belt assembly 22 includes a driving pulley 221, a driven pulley 222, and a synchronous belt 223. The driving pulley 221 is connected to the output end of the motor 21. The driven pulley 222 is installed at one end of a rolling component 4. The synchronous belt 223 is wound around the driving pulley 221 and the driven pulley 222. The motor 21 can drive a rolling component 4 connected to the driven pulley 222 to rotate through the synchronous belt assembly 22.

[0052] Since all the rolling components 4 are linked through the annular transmission member 3, when the output end of the driving component 2 is connected to any rolling component 4, the rotation of all the rolling components 4 can be achieved.

[0053] In one embodiment, as Figure 2 、 Figure 3As shown, a sprocket wheel 47 is provided on the rolling component 4. The annular conveyor 3 is a chain. The sprocket wheels 47 of multiple rolling components 4 are respectively engaged with the chain. When the driving component 2 drives the rolling component 4 connected thereto to rotate, the sprocket wheel 47 on this rolling component 4 rotates accordingly. Under the meshing action of the chain, the sprocket wheels 47 on the remaining rolling components 4 are driven by the chain to rotate, so that all the rolling components 4 rotate synchronously, and then the material plate is conveyed.

[0054] In an alternative embodiment, a pulley is provided on the rolling component 4. The annular conveyor 3 is a belt. The pulleys of multiple rolling components 4 are respectively connected to the belt in a transmission manner. Motion and power are transmitted between the belt and the pulley through friction. When the driving component 2 drives the rolling component 4 connected thereto to rotate, the pulley on this rolling component 4 rotates accordingly. Under the friction between the belt and the pulley, the pulleys on the remaining rolling components 4 are driven to rotate, so that all the rolling components 4 rotate synchronously, and then the material plate is conveyed.

[0055] In an alternative embodiment, a gear is provided on the rolling component 4. The annular conveyor 3 is an annular rack. The gears of multiple rolling components 4 are respectively engaged with the annular rack. When the driving component 2 drives the rolling component 4 connected thereto to rotate, the gear on this rolling component 4 rotates accordingly. Under the meshing action of the annular rack, the gears on the remaining rolling components 4 are driven by the annular rack to rotate, so that all the rolling components 4 rotate synchronously, and then the material plate is conveyed.

[0056] In one embodiment, as Figure 2 shown, the carrier plate 1 includes a bottom plate 11, a first side plate 12, a second side plate 13, a third side plate 14 and a fourth side plate 15. The first side plate 12, the second side plate 13, the third side plate 14 and the fourth side plate 15 are sequentially connected and arranged around the outer edge of the bottom plate 11. The first side plate 12 and the third side plate 14 are oppositely arranged in the first direction. The second side plate 13 and the fourth side plate 15 are oppositely arranged in the second direction. The first position is located at the first side plate 12, and the second position is located at the second side plate 13. The lower left corner of the carrier plate 1 is the junction of the first side plate 12 and the second side plate 13.

[0057] When the material plate moves along the first direction to the first side plate 12, it reaches the first position. When the material plate moves from the first position along the second direction to the second position, it reaches the second position.

[0058] Among them, multiple rolling components 4 are sequentially and evenly spaced along the first direction. Multiple rolling components 4 all extend along the second direction. The two ends of the rolling component 4 are respectively rotatably connected between the second side plate 13 and the fourth side plate 15, so that when the rolling component 4 rotates, it can drive the material plate to move along the first direction to the first position.

[0059] In one embodiment, as Figure 2 , Figure 3 shown, the rolling component 4 includes a connecting shaft 41 and a plurality of conveying wheels 42. The plurality of conveying wheels 42 are arranged at intervals on the connecting shaft 41. The connecting shafts 41 of the plurality of rolling components 4 are parallel to each other along the first direction a. The conveying wheels 42 and the connecting shaft 41 are relatively fixed. The driven wheel 222 is installed on the connecting shaft 41 of one rolling component 4. The motor 21 is connected to the connecting shaft 41 of one of the rolling components 4 through the synchronous belt assembly 22. Driven by the motor 21, when the connecting shaft 41 rotates, the conveying wheels 42 rotate following the connecting shaft 41, so as to drive the material plate to move along the first direction under the frictional force between the conveying wheels 42 and the material plate. The other ends of the remaining rolling components 4 are installed with sprockets 47, gears or belt pulleys to achieve the transmission connection with the annular conveyor 3.

[0060] Among them, the conveying wheel 42 is a Mecanum wheel. After reaching the first position, the position of the material plate in the first direction no longer changes. The Mecanum wheel can generate a leftward frictional force component applied to the material plate, so that the material plate moves from the first position to the second position along the second direction, realizing the movement of the material plate to the lower left corner for positioning.

[0061] Conventionally, the Mecanum wheels are divided into leftward wheels and rightward wheels. In this embodiment, the Mecanum wheel is a leftward wheel, which can position the material plate to the lower left corner of the carrier plate 1. In some alternative embodiments, a rightward wheel can be selected when the material plate needs to be positioned to the lower right corner.

[0062] In one embodiment, as Figure 2 shown, the second side plate 13 and the fourth side plate 15 are oppositely arranged in the second direction. The first embedded bearing 131 is arranged on the second side plate 13, and the second embedded bearing 151 is arranged on the fourth side plate 15. One end of the connecting shaft 41 is connected to the first embedded bearing 131, and the other end of the connecting shaft 41 passes through the second embedded bearing 151 and then is connected to the annular conveyor 3. The rotational connection of the connecting shaft 41 on the carrier plate 1 is realized through the first embedded bearing 131 and the second embedded bearing 151. The driving component 2 can drive the connecting shaft 41 connected thereto to rotate, and under the meshing action of the chain, the synchronous rotation of all the connecting shafts 41 is realized, so that the material plate is conveyed under the drive of the plurality of rolling components 4.

[0063] In one embodiment, as Figure 4 shown, the conveying wheel 42 includes a hub 421 and a plurality of rollers 422. The hub 421 is installed on the connecting shaft 41, and the plurality of rollers 422 are arranged around the outer peripheral surface of the hub 421. The central axis of the roller 422 is arranged at an angle of 45° with the central axis of the hub 421.

[0064] When the material plate moves along the first direction a to the first position, the hub 421 and the roller 422 are relatively stationary. Driven by the driving assembly 2, the connecting shaft 41 rotates, and the hub 421 and the roller 422 rotate together with the connecting shaft 41. The conveying wheel 42 has a frictional force along the first direction on the material plate, thereby pushing the material plate to move along the first direction towards the first position.

[0065] When the material plate moves from the first position to the second position along the second direction b, since the material plate and the carrier plate 1 remain relatively stationary in the first direction, with the continuous rotation of the connecting shaft 41, there is relative sliding between the material plate and the conveying wheel 42, causing the roller 422 to rotate relative to the hub 421, thereby generating a leftward frictional force component exerted by the roller 422 on the lower surface of the material plate, causing the material plate to move leftward until it reaches the second position.

[0066] In this embodiment, by setting the hub 421 and the roller 422, frictional forces in different directions can be generated on the material plate, thereby realizing the movement of the material plate towards the lower left corner.

[0067] In one embodiment, as Figure 4 shown, the conveying wheel 42 further includes a first conveying wheel frame 43 and a second conveying wheel frame 44. The first conveying wheel frame 43 and the second conveying wheel frame 44 are arranged on the opposite sides of the hub 421 in the axial direction. The roller 422 is rotatably connected between the first conveying wheel frame 43 and the second conveying wheel frame 44, so that when the material plate remains stationary in the first direction, the roller 422 can rotate relative to the hub 421. At this time, the roller 422 rotates towards the upper left direction, generating a frictional force towards the upper left direction on the material plate, and this frictional force has a leftward component force, thereby driving the material plate to move to the left.

[0068] In one embodiment, as Figure 3 、 Figure 4 shown, the rolling assembly 4 further includes a flat key 45 and a setscrew 46. The conveying wheel 42 is provided with a first keyway 4211 and a setscrew hole 4212. The first keyway 4211 extends along the axial direction of the conveying wheel 42 and communicates with the setscrew hole 4212. The connecting shaft 41 is provided with a second keyway 411 extending along its axial direction. The flat key 45 is arranged in the first keyway 4211 and the second keyway 411, so that the conveying wheel 42 is key-connected to the connecting shaft 41, and there is no relative circumferential rotation between the conveying wheel 42 and the connecting shaft 41. A plurality of second keyways 411 are arranged at intervals on each connecting shaft 41, so that a plurality of conveying wheels 42 can be installed at intervals on each connecting shaft 41.

[0069] The setscrew 46 is installed in the setscrew hole 4212 and abuts against the flat key 45. By means of the setscrew 46, the flat key 45 can be tightened, realizing the relative fixation of the conveying wheel 42 and the connecting shaft 41 in the axial direction, preventing relative axial sliding between the conveying wheel 42 and the connecting shaft 41, and further preventing the conveying wheel 42 from slipping off the connecting shaft 41.

[0070] Among them, the first keyway 4211 and the setscrew hole 4212 are arranged on the hub 421. The setscrew hole 4212 extends along the radial direction of the hub 421, and the first keyway 4211 penetrates the conveying wheel 42 axially, facilitating the sleeving of the conveying wheel 42 outside the connecting shaft 41.

[0071] In one embodiment, as Figure 4 shown, a first connecting groove 431 is provided on the first conveying wheel bracket 43, and a second connecting groove 441 is provided on the second conveying wheel bracket 44. When the first conveying wheel bracket 43 and the second conveying wheel bracket 44 are installed at the axial two ends of the hub 421, the first keyway 4211 can communicate the first connecting groove 431 and the second connecting groove 441. When installing the conveying wheel 42 on the connecting shaft 41, the flat key 45 can be avoided through the first connecting groove 431 and the second connecting groove 441, facilitating the disassembly and installation of the conveying wheel 42.

[0072] Specifically, when installing the conveying wheel 42 and the connecting shaft 41, first place the flat key 45 in the second keyway 411 of the connecting shaft 41. The flat key 45 can protrude from the outer peripheral surface of the connecting shaft 41. Then, align the first keyway 4211 on the conveying wheel 42 with the second keyway 411 and push the conveying wheel 42 to move relative to the connecting shaft 41. The first connecting groove 431 and the second connecting groove 441 can avoid the flat key 45. After pushing in place, the flat key 45 enters the first keyway 4211 and the second keyway 411. Finally, install the setscrew 46 in the setscrew hole 4212 so that the setscrew 46 abuts tightly against the flat key 45, realizing the relative fixation of the conveying wheel 42 and the connecting shaft 41.

[0073] In some alternative embodiments, at the axial two ends of the conveying wheel 42, an annular clamping groove is provided on the connecting shaft 41, and a snap ring is clamped in the clamping groove, which can also realize the relative fixation of the conveying wheel 42 and the connecting shaft 41 in the axial direction.

[0074] In one embodiment, as Figure 1 、 Figure 2 shown, the sheet positioning device further includes a first roller set 5. The first roller set 5 is arranged at the first position. The first roller set 5 is used to stop the sheet when the sheet moves along the first direction a and to guide the movement of the sheet along the second direction b. The first direction a is perpendicular to the second direction b.

[0075] The motor 21 drives the connecting shaft 41 to rotate through the synchronous belt assembly 22. The material plate moves along the first direction until it stops moving further along the first direction when it is blocked by the first roller group 5, which can limit the position of the material plate in the first direction and prevent the material plate from falling off the carrier plate 1.

[0076] After the material plate is blocked in the first direction, the conveying wheel 42 still rotates under the drive of the connecting shaft 41. At this time, relative sliding occurs between the conveying wheel 42 and the material plate, and the roller 422 rotates relative to the material plate and applies a frictional component force to the left to the material plate, causing the material plate to start moving along the second direction. The first roller group 5 guides the material plate to move to the lower left corner of the carrier plate 1 along the second direction.

[0077] In one embodiment, as Figure 2 shown, the first roller group 5 includes a first mounting plate 51 and a plurality of first rollers 52. The plurality of first rollers 52 are arranged at intervals on the first mounting plate 51. The material plate has a first edge, and the first edge is the edge on the side of the material plate close to the first mounting plate 51 in the first direction. The first edge is located at the front end of the material plate. The first roller 52 is used to abut against the first edge of the material plate on the side close to the first mounting plate 51. By providing a plurality of first rollers 52, the friction between the material plate and the first roller group 5 can be reduced when the material plate moves along the second direction, thereby reducing the friction damage of the material plate.

[0078] In one embodiment, as Figure 2 shown, the first roller group 5 further includes a first driving member 53 and a first sensor 54. The first driving member 53 is mounted on the carrier plate 1, and the output end of the first driving member 53 is connected to the first mounting plate 51. The first driving member 53 can drive the first mounting plate 51 to move along the first direction. Preferably, the first driving member 53 is a cylinder.

[0079] The first sensor 54 is mounted on the first mounting plate 51. The first sensor 54 is used to sense the first edge of the material plate. The position of the material plate can be determined through the first sensor 54. When the first sensor 54 senses the first edge, it indicates that the material plate has been blocked by the first roller 52. Then, the first driving member 53 drives the first mounting plate 51 to move along the first direction away from the carrier plate 1, so that the first sensor 54 is separated from the first edge of the material plate, facilitating that the material plate and the first sensor 54 do not interfere when the manipulator grabs the material plate. Among them, the first sensor 54 is a groove-type photoelectric sensor.

[0080] During the positioning process of the material plate, the output end of the first driving member 53 can maintain an extended state or a contracted state.

[0081] When the output end of the first driving member 53 is in the extended state, there is a gap between the first mounting plate 51 and the outer edge of the carrier plate 1. When the material plate moves to the first edge and senses the first sensor 54, the material plate stops moving. At this time, the first edge protrudes beyond the outer edge of the carrier plate 1, and the material plate extends a small distance beyond the first position. Then, the first driving member 53 drives the first mounting plate 51 to approach the carrier plate 1 in the first direction. The first roller 52 moves along with the first mounting plate 51 and pushes the material plate to move, eliminating this small distance so that the material plate reaches the first position, and the first edge of the material plate does not protrude beyond the outer edge of the carrier plate 1. When the manipulator needs to grasp the material plate, the first driving member 53 drives the first mounting plate 51 to move away from the carrier plate 1 in the first direction, so that the first sensor 54 is separated from the first edge of the material plate, avoiding interference between the material plate and the first sensor 54.

[0082] When the output end of the first driving member 53 is in the contracted state, the first mounting plate 51 is next to the outer edge of the carrier plate 1. When the first edge of the material plate senses the first sensor 54, the material plate stops moving. At this time, the material plate directly reaches the first position. Then, when the manipulator needs to grasp the material plate, the first driving member 53 drives the first mounting plate 51 to move away from the carrier plate 1 in the first direction, so that the first sensor 54 is separated from the first edge of the material plate, avoiding interference between the material plate and the first sensor 54.

[0083] In one embodiment, as Figure 1 、 Figure 2 shown, the material plate positioning device further includes a second roller group 6. The second roller group 6 is arranged at the second position. The second roller group 6 is used to stop the material plate when the material plate moves in the second direction b. When the material plate moves in the second direction, it is stopped by the second roller group 6, which can limit the position of the material plate in the second direction and prevent the material plate from falling off the carrier plate 1.

[0084] In one embodiment, as Figure 2 shown, the second roller group 6 includes a second mounting plate 61 and a plurality of second rollers 62. The plurality of second rollers 62 are arranged at intervals on the second mounting plate 61. The material plate has a second edge. The second edge is the edge of the material plate on the side close to the second mounting plate 61 in the second direction. The second edge is located at the left end of the material plate, and the first edge and the second edge are adjacent on the material plate. The second roller 62 is used to abut against the second edge of the material plate on the side close to the second mounting plate 61 and adjacent to the first edge. By arranging a plurality of second rollers 62, the contact area between the second edge of the material plate and the second roller group 6 can be reduced, thereby reducing the frictional force on the material plate and reducing frictional damage.

[0085] In one embodiment, as Figure 2As shown in the figure, the second roller group 6 further includes a second driving member 63 and a second sensor 64. The second driving member 63 is installed on the carrier plate 1. The output end of the second driving member 63 is connected to the second mounting plate 61, and the second driving member 63 can drive the second mounting plate 61 to move in the second direction. Preferably, the second driving member 63 is a cylinder.

[0086] The second sensor 64 is installed on the second mounting plate 61. The second sensor 64 is used to sense the second edge of the material plate. The position of the material plate can be determined through the second sensor 64. When the second sensor 64 senses the second edge, it indicates that the material plate has been blocked by the second roller 62. Then, the second driving member 63 drives the second mounting plate 61 to move away from the carrier plate 1 in the second direction, so that the second sensor 64 is separated from the second edge of the material plate, which is convenient for the manipulator to grasp the material plate without interference between the material plate and the second sensor 64. Among them, the second sensor 64 is a groove-type photoelectric sensor.

[0087] During the positioning process of the material plate, the output end of the second driving member 63 can maintain an extended state or a contracted state.

[0088] When the output end of the second driving member 63 is in the extended state, there is a gap between the second mounting plate 61 and the outer edge of the carrier plate 1. When the second edge of the material plate moves to the position where it senses the second sensor 64, the material plate stops moving. At this time, the second edge of the material plate protrudes from the outer edge of the carrier plate 1, and the material plate extends a small distance beyond the second position in the second direction. Then, the second driving member 63 drives the second mounting plate 61 to move closer to the carrier plate 1 in the second direction. The second roller 62 moves along with the second mounting plate 61 and pushes the material plate to move, eliminating this distance, so that the material plate reaches the second position, and the second edge of the material plate does not protrude from the outer edge of the carrier plate 1. When the manipulator needs to grasp the material plate, the second driving member 63 drives the second mounting plate 61 to move away from the carrier plate 1 in the second direction, so that the second sensor 64 is separated from the second edge of the material plate, avoiding interference between the material plate and the second sensor 64.

[0089] When the output end of the second driving member 63 is in the contracted state, the second mounting plate 61 is next to the outer edge of the carrier plate 1. When the second edge of the material plate senses the second sensor 64, the material plate stops moving. At this time, the material plate reaches the second position. Then, when the manipulator needs to grasp the material plate, the second driving member 63 drives the second mounting plate 61 to move away from the carrier plate 1 in the second direction, so that the second sensor 64 is separated from the second edge of the material plate, avoiding interference between the material plate and the second sensor 64.

[0090] As an example, such as Figure 2As shown, the sheet positioning device includes a first roller set 5 and a second roller set 6. The first roller set 5 includes a first driving member 53, a first sensor 54, a first mounting plate 51, and a plurality of first rollers 52. The second roller set 6 includes a second driving member 63, a second sensor 64, a second mounting plate 61, and a plurality of second rollers 62. The first driving member 53 and the second driving member 63 are cylinders, and the initial states of the first driving member 53 and the second driving member 63 are both extended states or contracted states.

[0091] When the initial states of both the first driving member 53 and the second driving member 63 are extended states, and the first driving member 53 and the second driving member 63 move synchronously, the sheet moves in the first direction until it abuts against the first rollers 52. Under the action of the rollers 422 of the conveying wheel 42, the sheet moves in the second direction until it abuts against the second rollers 62. At this time, the first sensor 54 is triggered by the first edge, and the second sensor 64 is triggered by the second edge. After both sensors are in the triggered state, the first driving member 53 drives the first mounting plate 51 to approach the carrier plate 1 in the first direction, and the first rollers 52 push the first edge to move. At the same time, the second driving member 63 drives the second mounting plate 61 to approach the carrier plate 1 in the second direction, and the second rollers 62 push the second edge to move, thereby correcting the position of the sheet so that the sheet moves to the second position. When the manipulator needs to grasp the sheet at the second position, the first driving member 53 drives the first mounting plate 51 to move away from the carrier plate 1 in the first direction, and at the same time, the second driving member 63 drives the second mounting plate 61 to move away from the carrier plate 1 in the second direction, to avoid interference between the sheet and the first sensor 54 and to avoid interference between the sheet and the second sensor 64.

[0092] When the initial states of both the first driving member 53 and the second driving member 63 are extended states, the first driving member 53 and the second driving member 63 can move independently of each other. When the sheet moves in the first direction until it abuts against the first rollers 52 and the first edge triggers the first sensor 54, the first driving member 53 drives the first mounting plate 51 to approach the carrier plate 1 in the first direction to correct the position of the sheet so that it is in the first position. Then, the sheet moves in the second direction until it abuts against the second rollers 62, and after the second edge triggers the second sensor 64, the second driving member 63 drives the second mounting plate 61 to approach the carrier plate 1 in the second direction to correct the position of the sheet so that it is in the second position. When it is necessary to grasp the sheet, the first driving member 53 drives the first mounting plate 51 to move away from the carrier plate 1 in the first direction, and the second driving member 63 drives the second mounting plate 61 to move away from the carrier plate 1 in the second direction, to avoid interference between the sheet and the first sensor 54 and to avoid interference between the sheet and the second sensor 64.

[0093] When the initial states of the first driving member 53 and the second driving member 63 are both in the contracted state, and when the first driving member 53 and the second driving member 63 move synchronously, when the material plate is abutted by the first roller 52, the first sensor 54 is triggered by the first edge, and the material plate reaches the first position. When the material plate is abutted by the second roller 62, the second sensor 64 is triggered by the second edge, and the material plate reaches the second position. After both sensors are in the triggered state, the first driving member 53 drives the first mounting plate 51 to move away from the carrier plate 1 in the first direction, and at the same time, the second driving member 63 drives the second mounting plate 61 to move away from the carrier plate 1 in the second direction, so as to avoid interference between the material plate and the first sensor 54 and avoid interference between the material plate and the second sensor 64.

[0094] On the other hand, an embodiment of the present invention provides a PCB processing device, including a machine table, a processing host, a loading manipulator, an unloading manipulator, and the material plate positioning device of the above embodiment. The loading manipulator is used to clamp the material plate when the material plate reaches the second position and transfer the material plate to the machine table. The processing host processes the material plate. The unloading manipulator unloads the material plate after the processing host finishes processing the material plate and moves the material plate out of the machine table.

[0095] Among them, the PCB processing device can be a drilling machine or a drilling and routing integrated machine.

[0096] In an embodiment, the PCB processing device is a laser drilling machine. The loading manipulator transfers the material plate to the machine table. The processing host is provided with a galvanometer scanner.
