[0002] During the PCB processing, the to-be-processed PCB in the magazine is grabbed by the loading manipulator and placed on the processing platform for drilling. The positioning of the main machine processing of the PCB processing device relies on the CCD to identify the target holes at the four corners of the PCB. When the loading manipulator places the PCB on the processing platform, the geometric error of the PCB does not exceed 6 mm, otherwise the target holes cannot completely appear within the CCD field of view and cannot be processed. Based on this, a positioning device is set in the loading machine system, and the to-be-processed PCB needs to be placed on the positioning device for positioning before being grabbed from the magazine and sent to the processing platform.

[0044] In order to make the technical problems, technical solutions and beneficial effects solved by the present utility model clearer and more understandable, 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.

[0045] As Figures 1 to 5 shown, a whole plate mechanism provided by an embodiment of the present utility model includes a carrier plate 1, a plurality of rolling components 2 and at least one pusher component 3. The plurality of rolling components 2 are arranged in parallel in sequence along the first direction a. The rolling components 2 are rotatably connected to the carrier plate 1. The material plate is placed on the rolling components 2. The plurality of rolling components 2 are used to drive the material plate placed on the rolling components 2 along the first direction a towards a preset position. Among them, "a plurality" means greater than or equal to two, and the meaning of "a plurality" is the same in each embodiment and will not be repeated hereinafter.

[0046] The pusher component 3 is installed on the carrier plate 1 and is arranged close to the preset position. During the process of the material plate moving towards the preset position, the pusher component 3 can be in contact with the material plate, and the pusher component 3 can drive the material plate to move along the second direction b towards the preset position, so that the material plate can be quickly moved to the preset position. Among them, the included angle between the second direction b and the first direction a is 0-90°.

[0047] In this embodiment, when positioning the material plate, after the material plate is placed on the rolling components 2, the material plate can move along with the rotation of the rolling components 2, so that the material plate moves along the first direction a. During the movement of the material plate, the material plate can be in contact with the pusher component 3, and the pusher component 3 gives a thrust to the material plate from the second direction b to adjust the position of the material plate. At this time, the plurality of rolling components 2 keep rotating, so that the material plate gradually approaches the preset position under the drive of the plurality of rolling components 2 and the drive of the pusher component 3, so that the material plate can be transported in place at one time, avoiding the situation of reducing the positioning efficiency caused by repeatedly opening and contracting the cylinder to perform whole plate, and can improve the positioning efficiency of the material plate.

[0048] The material board is a PCB. The preset position of the PCB is at the lower left corner of the carrier board 1. The PCB needs to move from the center of the carrier board 1 to the lower left corner. Taking the lower left corner of the carrier board 1 as the origin, a rectangular coordinate system is defined to determine the X-axis and Y-axis. For a PCB with a relatively large aspect ratio, when multiple rolling components 2 drive the PCB to move from the center position towards the lower left corner, due to the large difference in the component displacements of the PCB in the X / Y directions, the PCB cannot directly move to the lower left corner position during the conveying process. When the rolling components 2 convey the PCB to contact the pusher component 3, there is still a certain deviation between the position of the PCB and the preset position. The pusher component 3 deflects the material. At this time, the rolling components 2 convey the material board in the first direction, and the pusher component 3 conveys the material board in the second direction. Under the combined action of the frictional force of the rolling components 2 and the frictional force of the pusher component 3, the material board is pushed to continue approaching the lower left corner, eliminating the deviation in position. For any PCB with any aspect ratio, the PCB can be sent to the preset position at one time, without the need to drive the claw to deflect the material repeatedly through a cylinder, improving the positioning efficiency of the material board.

[0049] In a preferred embodiment, as Figure 2 shown, the first direction a is inclined with respect to the X / Y direction, and the second direction b is the X direction or the Y direction. Preferably, the first direction a is set along the 45-degree direction, that is, the first direction a intersects the X-axis and the Y-axis, and the included angle is 45 degrees, so that the PCB can quickly approach the lower left corner under the drive of the rolling components 2.

[0050] In an embodiment, as Figure 3 、 Figure 4 shown, the pusher component 3 includes a substrate 31, a first driving member 32, a driving wheel 33, a driven wheel 34, and a connecting belt 35. The substrate 31 is installed on the carrier board 1, and the first driving member 32, the driving wheel 33, and the driven wheel 34 are all installed on the substrate 31. The output end of the first driving member 32 is connected to the driving wheel 33. The first driving member 32 can drive the driving wheel 33 to rotate. The connecting belt 35 is wound around the driving wheel 33 and the driven wheel 34. Under the combined action of the driving wheel 33 and the connecting belt 35, the first driving member 32 drives the connecting belt 35 to move through the driving wheel 33. When the first driving member 32 drives the connecting belt 35 to move, under the frictional force between the connecting belt 35 and the material board, the material board in contact with the connecting belt 35 can be driven to move, thereby realizing deflecting the material of the material board and making the material board move towards the preset position.

[0051] Wherein, a connecting frame 311 is fixed on the substrate 31, and the first driving member 32 is installed on the substrate 31 through the connecting frame 311. A first connecting shaft 312 is installed on the substrate 31. The end of the first connecting shaft 312 far from the substrate 31 is rotatably connected to the driven wheel 34, so that when the first driving member 32 drives the driving wheel 33 to rotate, the driven wheel 34 cooperates with the connecting belt 35 to realize power transmission.

[0052] In one embodiment, the first driving member 32 is a stepper motor.

[0053] In one embodiment, as Figure 3 , Figure 4 shown, a plurality of ridges 351 are provided on the connecting belt 35. The plurality of ridges 351 are arranged at intervals along the circumferential direction of the connecting belt 35. The connecting belt 35 surrounds the driving wheel 33 and the driven wheel 34 to form an annular structure. The inner surface of the connecting belt 35 abuts against the driving wheel 33 and the driven wheel 34. The ridges 351 are provided on the outer surface of the connecting belt 35. The ridges 351 can abut against the material plate. When the first driving member 32 drives the driving wheel 33 to rotate and drives the connecting belt 35 to move, the connecting belt 35 can drive the material plate to move through the ridges 351. When the connecting belt 35 contacts the material plate, the ridges 351 can increase the friction between the connecting belt 35 and the material plate, ensuring that the material plate can be toggled to move when the connecting belt 35 moves.

[0054] Preferably, the connecting belt 35 is a crawler belt, the driving wheel 33 and the driven wheel 34 are gears with teeth, and the first driving member 32 can drive the connecting belt 35 to move through the driving wheel 33 and the driven wheel 34.

[0055] In an alternative embodiment, the connecting belt 35 is a timing belt, the driving wheel 33 and the driven wheel 34 are timing pulleys. When the first driving member 32 drives the timing belt to move, the timing belt can toggle the material plate to move and approach a preset position.

[0056] In one embodiment, as Figure 3 , Figure 4 shown, ribs 352 are provided on the inner surface of the connecting belt 35. The ribs 352 extend along the circumferential direction of the connecting belt 35. A first rib groove 331 is provided on the driving wheel 33, and a second rib groove 341 is provided on the driven wheel 34. The ribs 352 are embedded in the first rib groove 331 and the second rib groove 341. During the movement of the connecting belt 35, the ribs 352 remain in the first rib groove 331 and the second rib groove 341, and can prevent the connecting belt 35 from axially disengaging from the driving wheel 33 and the driven wheel 34 during the movement process, avoiding affecting the material toggling of the connecting belt 35 on the material plate. At the same time, it plays a limiting role in the cooperation between the connecting belt 35 and the driving wheel 33 and the cooperation between the connecting belt 35 and the driven wheel 34, reducing the transmission error caused by position deviation, helping to improve the transmission accuracy and stability, and ensuring the normal operation of the connecting belt 35.

[0057] Among them, the ribs 352 are annular, the first rib groove 331 and the second rib groove 341 are annular grooves. The first rib groove 331 is located at the middle position of the driving wheel 33 in the axial direction of the driving wheel 33, and the second rib groove 341 is located at the middle position of the driven wheel 34 on the bearing of the driven wheel 34, further ensuring the stability of the connecting belt 35 during the transmission process.

[0058] In one embodiment, as Figure 3 、 Figure 4 shown, the pusher assembly 3 further includes at least one idler pulley 36. The idler pulley 36 is installed on the base plate 31. The idler pulley 36 is arranged between the driving pulley 33 and the driven pulley 34, and plays a transitional role through the idler pulley 36, which can increase the transmission distance of the connecting belt 35. The number of idler pulleys 36 is set according to the requirement of the transmission distance of the connecting belt 35. The number of idler pulleys 36 can be one, two or more. When the number of idler pulleys 36 is two or more, all the idler pulleys 36 are arranged at intervals between the driving pulley 33 and the driven pulley 34.

[0059] A third rib groove 361 is provided on the idler pulley 36, and the rib 352 is embedded in the third rib groove 361, which can prevent the connecting belt 35 from disengaging from the idler pulley 36 along the axial direction of the idler pulley 36 during movement, avoiding affecting the material pushing of the connecting belt 35 on the material plate. At the same time, it plays a limiting role in the cooperation between the connecting belt 35 and the idler pulley 36, reduces the transmission error caused by the position deviation, helps to improve the transmission accuracy and stability, and ensures the normal operation of the connecting belt 35.

[0060] Among them, the third rib groove 361 is an annular groove, and the third rib groove 361 is located at the middle position of the idler pulley 36 in the axial direction of the idler pulley 36, further ensuring the stability of the connecting belt 35 during transmission.

[0061] In one embodiment, as Figure 3 、 Figure 4 shown, the pusher assembly 3 further includes a first bevel gear 37 and a second bevel gear 38. The first bevel gear 37 is installed on the output end of the first driving member 32. The second bevel gear 38 and the driving pulley 33 are coaxially arranged. The first bevel gear 37 and the second bevel gear 38 are meshed. When the first driving member 32 drives the first bevel gear 37 to rotate, under the meshing action of the first bevel gear 37 and the second bevel gear 38, the second bevel gear 38 rotates, and then the driving pulley 33 coaxial with the second bevel gear 38 can rotate, realizing the movement of the connecting belt 35. In this embodiment, the transmission connection between the first driving member 32 and the driving pulley 33 is realized through the first bevel gear 37 and the second bevel gear 38, so that the driving pulley 33 can rotate under the drive of the first driving member 32.

[0062] Among them, the first bevel gear 37 and the second bevel gear 38 are 45° bevel gears, which can change the transmission direction of the output end of the first driving member 32 while meshing.

[0063] In one embodiment, as Figure 4As shown, the second bevel gear 38 and the driving wheel 33 are connected by a second connecting shaft 39. The second connecting shaft 39 penetrates through the substrate 31. One end of the second connecting shaft 39 is connected to the second bevel gear 38, and the other end of the second connecting shaft 39 is connected to the driving wheel 33. In this way, when the first driving member 32 drives the second bevel gear 38 to rotate through the first bevel gear 37, the driving wheel 33 and the second bevel gear 38 rotate together, thereby realizing the movement of the connecting belt 35.

[0064] In one embodiment, as Figure 1 , Figure 2 shown, at least one pushing component 3 includes a first pushing component 3a and a second pushing component 3b. The first pushing component 3a is installed on one side of the carrier plate 1 in the second direction b, and the second pushing component 3b is installed on one side of the carrier plate 1 in the third direction c. The second direction b and the third direction c are neither parallel nor coincident. The first pushing component 3a can drive the material plate to move along the third direction c towards a preset position, and the second pushing component 3b can drive the material plate to move along the second direction b towards a preset position. When the material plate abuts against the first pushing component 3a, the first pushing component 3a can apply a thrust to the material plate in the third direction c to adjust the position of the material plate, so that the material plate gradually approaches the preset position along the third direction c. When the material plate abuts against the second pushing component 3b, the second pushing component 3b can apply a thrust to the material plate in the second direction b to adjust the position of the material plate, so that the material plate gradually approaches the preset position along the second direction b.

[0065] During the process of the plurality of rolling components 2 driving the material plate towards the preset position, regardless of the aspect ratio of the material plate, when the rolling components 2 transport the material plate to contact any one of the first pushing component 3a and the second pushing component 3b, the material plate will continue to move towards the preset position under the combined action of the frictional force of the rolling components 2 and the frictional force of the pushing component 3. Or when the rolling components 2 transport the material plate to contact both the first pushing component 3a and the second pushing component 3b simultaneously, the material plate will continue to move towards the preset position under the combined action of the frictional force of the rolling components 2, the frictional force of the first pushing component 3a, and the frictional force of the second pushing component 3b.

[0066] Among them, as Figure 2 shown, the second direction b and the third direction c are perpendicular, the second direction b is the X direction, the third direction c is the Y direction, the first direction a is the 45° direction, the first pushing component 3a is located on the left side of the carrier plate 1 as Figure 2 shown, and the second pushing component 3b is located on the lower side of the carrier plate 1 as Figure 2 shown.

[0067] In one embodiment, the first pushing component 3a and the second pushing component 3b have the same structure. The first pushing component 3a and the second pushing component 3b both include a substrate 31, a first driving member 32, a driving wheel 33, a driven wheel 34 and a connecting belt 35. The connecting belt 35 of the first pushing component 3a can drive the material plate to gradually approach a preset position along a third direction, and the connecting belt 35 of the second pushing component 3b can drive the material plate to gradually approach the preset position along a second direction.

[0068] In one embodiment, as Figure 1 , Figure 5 shown, the whole plate mechanism further includes a first sensor 41 and a second sensor 42. The first sensor 41 and the first pushing component 3a are arranged on the same side of the carrier plate 1. The first sensor 41 is closer to the lower left corner of the carrier plate 1 than the first pushing component 3a. The first sensor 41 is used to sense one side edge of the material plate in the second direction. The second sensor 42 and the second pushing component 3b are arranged on the same side of the carrier plate 1. The second sensor 42 is closer to the lower left corner of the carrier plate 1 than the second pushing component 3b. The second sensor 42 is used to sense one side edge of the material plate in the third direction. When the first sensor 41 and the second sensor 42 are triggered simultaneously, it indicates that the material plate has reached the preset position. The first sensor 41 and the second sensor 42 can send out a signal that the material plate has reached the preset position, which is convenient for the manipulator to grasp the positioned material plate.

[0069] During the process that the plurality of rolling components 2 drive the material plate to move towards the preset position, when the material plate first contacts the first pushing component 3a, the first driving member 32 of the first pushing component 3a drives the material plate towards the preset position through the connecting belt 35. The material plate moves towards the preset position under the drive of the rolling components 2 and the first pushing component 3a. When the material plate moves towards the preset position along the third direction, the material plate can trigger the first sensor 41. At the same time, the material plate can approach the second pushing component 3b in the third direction. Under the drive of the second pushing component 3b, the material plate approaches the preset position along the second direction until the material plate triggers the second sensor 42. At this time, the first sensor 41 and the second sensor 42 are triggered simultaneously, indicating that the material plate has reached the preset position, and the rolling components 2, the first pushing component 3a and the second pushing component 3b stop moving.

[0070] In one embodiment, the first sensor 41 and the second sensor 42 are groove type photoelectric sensors, which can sense the edge of the material plate.

[0071] In one embodiment, as Figure 5As shown, the whole board mechanism further includes a second driving member 43 and a connecting bracket 44. The first sensor 41 and the second sensor 42 are installed on the connecting bracket 44, and the second driving member 43 is installed on the carrier plate 1. The output end of the second driving member 43 is connected to the connecting bracket 44. By means of the second driving member 43, the first sensor 41 and the second sensor 42 can be driven to move, so that after the material plate is in place, the second driving member 43 can drive the first sensor 41 and the second sensor 42 to disengage from the edge of the material plate, so that when the manipulator grabs the material plate, there will be no interference between the material plate and the first sensor 41, and there will be no interference between the material plate and the second sensor 42.

[0072] Among them, the second driving member 43 is a cylinder.

[0073] Further, the connecting bracket 44 includes a first plate member 441, a second plate member 442 and a third plate member 443. The first sensor 41 is installed on the first plate member 441, the second sensor 42 is installed on the second plate member 442, and the first plate member 441 and the second plate member 442 are connected to opposite ends of the third plate member 443. The second driving member 43 drives the first sensor 41 and the second sensor 42 to move together through the connecting bracket 44.

[0074] In one embodiment, as Figure 1 、 Figure 2 shown, the whole board mechanism further includes a third driving member 6 and a plurality of synchronizing components 5. The third driving member 6 is installed on the carrier plate 1. The output end of the third driving member 6 is connected to any one of the rolling components 2. Any two adjacent rolling components 2 are connected by a synchronizing component 5 to realize the linkage of the plurality of rolling components 2. The third driving member 6 can drive the rolling component 2 connected thereto to rotate, and drive other rolling components 2 to rotate through the synchronizing component 5, so as to be able to move the material plate placed on the rolling component 2 towards a preset position along the first direction a. After the material plate moves to the preset position, it is grabbed by the manipulator and sent to the PCB processing equipment.

[0075] In this embodiment, when positioning the PCB board, all the rolling components 2 can be connected in series through a plurality of synchronizing components 5. The third driving member 6 drives the rolling component 2 connected to it to rotate, and this rolling component 2 drives the two adjacent rolling components 2 to rotate through the synchronizing component 5, transmitting power in sequence, so that all the rolling components 2 rotate. After the PCB is placed on the rolling component 2, the PCB can move as the rolling component 2 rotates, so that the PCB moves along the first direction. After the PCB contacts the first pusher component 3a and / or the second pusher component 3b, the PCB approaches the preset position under the combined action of the rolling component 2 and the pusher component 3.

[0076] In one embodiment, as Figure 1As shown in the figure, the third driving member 6 includes a motor 61 and a synchronous belt assembly 62. The synchronous belt assembly 62 includes a first synchronous pulley 621, a second synchronous pulley 622, and a second synchronous belt 623. The second synchronous belt 623 is wound around the first synchronous pulley 621 and the second synchronous pulley 622. The first synchronous pulley 621 is connected to the output end of the motor 61, and the second synchronous pulley 622 is arranged on a rolling assembly 2. Under the drive of the synchronous belt assembly 62, the motor 61 can drive the rolling assembly 2 to rotate.

[0077] Among them, since all the rolling assemblies 2 are linked through a synchronous assembly 5, when the output end of the motor 61 is connected to any one of the rolling assemblies 2, the rotation of all the rolling assemblies 2 can be realized. Preferably, among the multiple rolling assemblies 2 arranged in parallel, the output end of the motor 61 is connected to the rolling assembly 2 at the middle position, which can reduce the hysteresis of the rolling assembly 2 farther away from the motor 61. The motor 61 drives the rolling assembly 2 at the middle position to rotate, and this rolling assembly 2 drives the two adjacent rolling assemblies 2 to rotate through the synchronous assembly 5. Then, the transmission is carried out step by step to both sides in turn to realize the rotation of all the rolling assemblies 2, so as to transport the material plate.

[0078] In one embodiment, as Figure 1 shown, the rolling assembly 2 includes a roller shaft 21 and a plurality of rollers 22. The plurality of rollers 22 are arranged in parallel at intervals along the first direction. The motor 61 is connected to a roller shaft 21 through the synchronous belt assembly 62, and the roller shaft 21 and the rollers 22 rotate synchronously. All the roller shafts 21 are arranged in parallel along the first direction, and the PCB is placed on the rollers 22. By the motor 61, all the roller shafts 21 can be driven to rotate, and the rollers 22 roll along with the roller shaft 21, so as to drive the PCB to move obliquely on the carrier plate 1.

[0079] As Figure 2 shown, the synchronous assembly 5 includes a first connecting pulley 52, a second connecting pulley 53, and a first synchronous belt 51. The first connecting pulley 52 and the second connecting pulley 53 are respectively arranged on any two adjacent roller shafts 21, that is, the first connecting pulley 52 is arranged on one of any two adjacent roller shafts 21, and the second connecting pulley is arranged on the other of any two adjacent roller shafts 21. The first synchronous belt 51 is wound around the first connecting pulley 52 and the second connecting pulley 53. When the driving member drives one of any two adjacent roller shafts 21 to rotate, through the first synchronous belt 51, the first connecting pulley 52 and the second connecting pulley 53 can be driven to rotate, so that the other roller shaft 21 rotates in the same direction, and the two adjacent roller shafts 21 rotate synchronously, thereby driving the material plate to be transmitted.

[0080] Among them, as Figure 2As shown, in the first direction, a plurality of rollers 21 arranged in parallel are sequentially sorted as 1, 2... n in the direction of the lower left corner. To enable the rotation of all the rollers 21, except for the outermost first roller 21 and the nth roller 21, a first connecting wheel 52 and a second connecting wheel 53 are provided on each of the remaining rollers 21. One of the first roller 21 and the nth roller 21 is provided with a first connecting wheel 52, and the other is provided with a second connecting wheel 53. For example, the second roller 21 is located between the first roller 21 and the third roller 21 in the first direction. The first connecting wheel 52 on the second roller 21 is connected to the second connecting wheel 53 on the first roller 21 through a first synchronous belt 51, and the second connecting wheel 53 on the second roller 21 is connected to the first connecting wheel 52 on the third roller 21 through a first synchronous belt 51. Arranged in this way successively, all the roller 21 assemblies are connected, and as long as one roller 21 rotates, the rotation of all the rollers 21 can be achieved, thereby realizing the conveying of the material plate.

[0081] In one embodiment, as Figure 1 shown, the carrier plate 1 further includes a plate edge support member 11. The plate edge support member 11 is provided on one side of the carrier plate 1 in the second direction and on one side of the carrier plate 1 in the third direction, that is, the plate edge support member 11 is provided on the left edge of the carrier plate 1 as shown in Figure 2 and on the lower edge of the carrier plate 1 as shown in Figure 2 . When the PCB moves to the lower left corner, by providing the plate edge support member 11 on the left side and the lower side of the carrier plate 1, the carrier plate 1 can be prevented from scratching the PCB board. Among them, the plate edge support member 11 is made of a non-metallic material.

[0082] On the other hand, an embodiment of the present invention provides a PCB processing device, including a machine table, a processing host, a loading and unloading mechanism, and the whole plate mechanism of the above embodiment. The processing host is arranged on the machine table. The processing host is used for processing the material plate. The whole plate mechanism is arranged on the loading and unloading mechanism. A loading manipulator and an unloading manipulator are installed on the loading and unloading mechanism. Before the material plate is sent into the machine table, the position of the material plate is positioned by the whole plate mechanism. The loading manipulator is used to clamp the material plate and transfer the material plate to the machine table when the material plate reaches the preset position. The unloading manipulator is used to unload the material plate processed by the processing host.

[0083] Among them, the PCB processing device can be a drilling machine or a drilling and routing integrated machine.

[0084] In one embodiment, the PCB processing device is a laser drilling machine. The loading manipulator transfers the material plate to the machine table. The processing host has a galvanometer. After the laser beam reaches the galvanometer, an accurate laser beam is emitted by the galvanometer, so that the material plate can be drilled. After processing, it is unloaded by the unloading manipulator.

[0085] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
