When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

It should be noted that, in this embodiment, terms of left, right, up, down, etc. are merely relative concepts or references to normal use states of the product, and should not be construed as limiting.

As shown in fig. 1, a schematic perspective view of a processing system 100 according to an embodiment of the invention is shown, where the processing system 100 includes a blanking device 101. Fig. 2 to fig. 4 are schematic diagrams related to a blanking device 101 according to an embodiment of the present invention, where the blanking device 101 includes a blanking mechanism 10 and a blocking assembly 20.

The blanking mechanism 10 comprises a blanking frame 11 and a blanking platform 12 for bearing a to-be-blanked plate, the blanking platform 12 is rotationally connected with the blanking frame 11, the blanking platform 12 is provided with a first preset position (see fig. 3) which is horizontal relative to the ground and a second preset position (see fig. 4) which is rotated by a certain angle relative to the first preset position, and when the blanking platform 12 is positioned at the second preset position, the to-be-blanked plate P on the blanking platform 12 can slide off the blanking platform 12 due to dead weight; the material blocking assembly 20 comprises a blocking plate 21 which can move relative to the blanking platform 12, and the blocking plate 21 has a blocking state and a unblocking state; in the stop state, the stop plate 21 can stop the blanking plate P to be blanked from sliding down from the blanking platform 12 in the process that the blanking platform 12 rotates from the first preset position to the second preset position, and in the unblock state, the stop plate 21 can unblock the blanking plate P to be blanked after the blanking platform 12 reaches the second preset position.

With further reference to fig. 5, fig. 5 shows a schematic view of the blanking device 101 of the processing system 100 during blanking. The blanking plate P can be a leftover plate and a base plate, wherein the leftover plate is left after machining and is arranged below the leftover plate, for example, the blanking plate is a PCB, the leftover plate is a PCB leftover material generated in the machining process of drilling the PCB, and the like, the base plate is usually a paperboard, can play a role in machining, buffering, supporting and collecting the leftover plate, and can be reused; if the finished product material plate obtained after the processing is transferred from the blanking platform 12 through a picking mechanism such as a manipulator, the material plate P to be blanked on the blanking platform 12 is the leftover material plate and the backing plate which are remained after the processing, and at this time, the blanking object of the blanking mechanism 10 is the leftover material plate and the backing plate. When the blanking platform 12 is positioned at the first preset position, the blanking plate P to be blanked on the blanking platform 12 is in a horizontal state, and when the blanking platform 12 rotates from the first preset position to the second preset position, the blanking platform 12 starts to incline relative to the ground (namely, the horizontal position) and the inclination angle is gradually increased, and the blanking plate P to be blanked also starts to incline gradually relative to the ground; in the process that the blanking platform 12 rotates from the first preset position to the second preset position gradually, the stop plate 21 of the material blocking assembly 20 is always in a stop state to stop the material plate P to be blanked, so that the material plate P to be blanked is prevented from falling and tilting and moving, after the blanking platform 12 reaches the second preset position, the stop plate 21 is switched to a stopping state, the blocking of the material plate P to be blanked is relieved, the material plate P to be blanked automatically slides off the blanking platform 12 due to dead weight, and therefore the material plate P to be blanked does not need to be manually taken down from the blanking platform 12, the blanking efficiency and the production efficiency can be improved, the probability of shutdown caused by untimely blanking is greatly reduced, and the utilization rate of equipment is improved. It should be noted that, in the present embodiment, the inclination angle of the second preset position may be preset and adjusted according to the actual conditions of the height of the blanking platform 12 relative to the ground, the size of the material plate, etc., and the present invention is not limited to the inclination angle of the second preset position relative to the ground, and when the size of the material plate to be processed is different, the inclination angle of the second preset position of the blanking platform 12 relative to the ground may also be different.

In other embodiments, the plate P to be blanked may be a finished plate and/or a pad plate at the bottom of the finished plate, for example, when the plate P to be blanked is a finished plate and pad plate obtained after finishing processing, that is, the blanking mechanism 10 finishes blanking the finished plate and pad plate, that is, the leftover plate may be first turned away by a manipulator or the like, and the rest of the finished plate and pad plate is blanked by the blanking mechanism 10.

In the present embodiment, in one discharging device 101, the number of the discharging mechanisms 10 to be provided is not limited. When a plurality of discharging mechanisms 10 are provided, the plurality of discharging mechanisms 10 may be arranged side by side, as shown in fig. 2 and 3, and the number of the material blocking assemblies 20 corresponds to the number of the discharging mechanisms 10, that is, each discharging mechanism 10 is at least provided with one material blocking assembly 20.

In some embodiments, the stop plate 21 is disposed on one side of the blanking platform 12, and the stop assembly 20 further includes a stop driving member 22, where the stop driving member 22 is connected to the stop plate 21 and can drive the stop plate 21 to switch between a stop state and an unblocking state.

The blanking platform 12 comprises a base 121 and supporting bars 122, the supporting bars 122 are arranged on the edge of the base 121, the base 121 is rotatably connected with one side of the blanking frame 11, the supporting bars 122 are used for placing a material plate to be blanked, and particularly when the size of the material plate is large, the supporting bars 122 arranged on the edge of the base 121 can play a role in supporting the edge of the material plate in order to prevent the edge of the material plate from sagging. The cross section of the baffle plate 21 is L-shaped, the baffle plate 21 can ascend and descend relative to the base 121, when the baffle plate 21 ascends, the side plates of the baffle plate 21 protrude out of the base 121 and the top ends of all parts on the base 121, so that when the blanking platform 12 rotates from a first preset position which is horizontal to the ground to a second preset position which has a certain included angle with the ground, the side plates of the baffle plate 21 can block the material plate to prevent the material plate from not reaching the second preset position, and the material plate P to be blanked can slide from the blanking platform 12, so that the material plate P to be blanked can slide at the preset position to enable the blanking of the material plate P to be blanked to be in a controllable state, and the blanking position can be conveniently adjusted according to the size of the material plate and the like. The stop driving member 22 is used for driving the stop plate 21 to move up and down, in this embodiment, the stop driving member 22 is a cylinder, however, other driving structures such as an oil cylinder, a motor, a ball screw pair, etc. can be used for the stop driving member 22.

As shown in fig. 6, the blanking platform 12 has a third preset position in addition to the first preset position and the second preset position, when the blanking platform 12 is in the third preset position, the blanking platform 12 is in a vertical or substantially vertical state with respect to the ground, that is, the blanking platform 12 rotates by about 90 degrees from the first preset position to the third preset position, and when the blanking platform 12 is in the first preset position, the blanking platform 12 is in a horizontal state, and the blanking platform 12 is disposed on one side of the blanking frame 11, so that the blanking platform 12 occupies relatively a relatively large space in a horizontal direction, particularly, when a plurality of blanking platforms 12 are side by side, the space occupied in a production workshop is larger, therefore, if the blanking platform 12 is rotated to a position vertical to the ground, that is, the blanking platform 12 is in a folded state with respect to the blanking frame 11, the space occupied in the horizontal direction by the blanking platform 12 can be greatly reduced, and more gaps can be reserved between the blanking mechanism 10 and other mechanisms, thereby facilitating the maintenance of the blanking mechanism 10 by a small car.

In some embodiments, referring to fig. 3 and 4, the blanking platform 12 is rotatably connected with the blanking frame 11 through a bearing; the blanking mechanism 10 further comprises a rotary driving assembly 23 connected with the blanking platform 12, wherein the rotary driving assembly 23 comprises a rotary driving cylinder 231, one end of the rotary driving cylinder 231 is fixedly connected with the blanking frame 11, and the output end of the rotary driving cylinder 231 is hinged with the bottom of the base 121 of the blanking platform 12.

The rotation connection between the blanking platform 12 and the blanking frame 11 can be realized through a bearing, of course, the rotation connection can also be realized through a universal ball head and other conventional structures with rotation functions, and through the joint cooperation of the tail end of the output end (namely the piston rod 2311) of the rotary driving cylinder 231 and the bottom of the blanking platform 12, the blanking platform 12 can not only rotate from a first preset position to a second preset position and a third preset position, but also can enable the blanking platform 12 to be kept and stay at the current preset position so as to facilitate related operation.

In some embodiments, the blanking device 101 further includes a rim charge conveying line 90 that is disposed at an interval with the blanking mechanism 10 and is used for transferring the rim charge plate p1 and the backing plate p2, the rim charge conveying line 90 is disposed adjacent to the baffle assembly 20, the rim charge conveying line 90 includes a rim charge conveying belt 91, and after the blanking platform 12 reaches the second preset position, the rim charge plate p1 and the backing plate p2 carried on the blanking platform 12 can fall onto the rim charge conveying belt 91 after sliding from the blanking platform 12.

The height of the rim charge conveying belt 91 relative to the ground is lower than the height of the blanking platform 12 relative to the ground, so that the rim charge plate p1 and the backing plate p2 sliding on the blanking platform 12 can slide onto the rim charge conveying belt 91, after the blanking platform 12 reaches the second preset position, the stop plate 21 of the material blocking assembly 20 is retracted under the driving of the stop driving piece 22, the stop plate 21 does not block the rim charge plate p1 and the backing plate p2 on the blanking platform 12 any more, the rim charge plate p1 and the backing plate p2 can slide onto the rim charge conveying belt 91, and it is worth noting that the process of sliding the rim charge plate p1 and the backing plate p2 on the blanking platform 12 onto the rim charge conveying belt 91 is gradual, as the blanking platform 12 continues to rotate from the second preset position, the rim charge plate p1 and the backing plate p2 rest on the rim charge conveying belt 91 from one side and the other side until the rim charge plate p1 and the backing plate p2 are all placed on the rim charge conveying belt 91, and then the rim charge plate p1 and the backing plate p2 are moved to a station by the step of the step plate p1 and the blanking platform 2.

The processing module 30 is used for processing the to-be-processed board, in one processing system 100, the process of processing the to-be-processed board by the processing module 30 may be considered as a pre-process of blanking the to-be-processed board P by the blanking mechanism 10, that is, after the to-be-processed board completes the processing process on the processing module 30, the finished board b and the leftover board P1 are formed, and then the finished board b and the leftover board P1 and the backing board P2 at the bottom of the finished board b and the leftover board P1 are all transferred onto the blanking platform 12 by the clamping assembly 50 to be ready for blanking. The nip assembly 50 may be disposed on the blanking platform 12. The processing module 30 includes, in addition to the material bearing plate 31 and the material ejecting device 32, a spindle assembly (not shown in the figure) for processing the material plate to be processed, where the spindle assembly may include a drill for performing drilling and cutting processing, so as to perform corresponding processing on the material plate to be processed. In order to stably position the material plate to be processed in the processing process, positioning pins 33 can be further arranged on the material bearing plate 31 to position the material plate to be processed.

The ejector pin assembly 321 is used for ejecting the processed material plate away from the material bearing plate 31, so that the material plate is separated from the material bearing plate 31 and the positioning pins 33 on the material bearing plate 31, thereby being convenient for preparing for the next transfer. The ejector driving component 322 drives the ejector pin component 321 to act, so that the ejector pin component 321 can resist against the processed material plate, and the ejector driving component 322 can drive the ejector pin component 321 to ascend and descend.
