The embodiment of the utility model provides a processing equipment can realize taking, transporting and the location to the automation of work piece. The workpiece includes, but is not limited to, a circuit board, and the processing of the workpiece is not limited to punching. For example, the workpiece is a circuit board, and both sides of the board surface (surface with the normal line in the thickness direction) of the circuit board may be pre-fitted with positioning portions (not limited to the shapes of pins, posts, blocks, bars, etc.) for positioning the circuit board (described in detail below). After the machining is completed, the positioning portion may be removed. Of course, the workpiece may be another workpiece having a shape similar to that of the circuit board.

As shown in fig. 1-3, in one embodiment, the processing apparatus 10 may include a carrier frame 13, a support frame 12, a positioning platform 11, a transport cart 14, and a robotic arm 15.

The supporting frame 12 may be a frame constructed by a plurality of beams or rods, and is used for mounting the loading frame 13 and supporting the transport vehicle 14. Preferably, the support frame 12 may include a first support frame 122 and a second support frame 121 which are connected together. The first support frame 122 supports the transport cart 14 (and the robot arm 15) thereon, and the transport cart 14 may be placed on top of the first support frame 122. To ensure smooth travel of the transport vehicle 14, the first support frame 122 may be laid with the first tie plates 16, and the transport vehicle 14 may rest on the first tie plates 16 in the initial position and may travel over the first tie plates 16. The second support frame 121 is provided with a carrier frame 13, and the carrier frame 13 can be embedded in the frame of the first support frame 122. The material loading frame 13 may also be a frame body built by a plurality of beams or rods, and is used for loading workpieces. In other embodiments, the structures of the supporting frame 12 and the carrier frame 13 are not limited to this, and any structure may be used as long as it has a load-bearing capacity.

The positioning platform 11 is located on one side of the material loading frame 13. The positioning platform 11 is used for receiving the workpiece from the material loading frame 13, positioning the workpiece and facilitating processing of the workpiece. The positioning platform 11 may position the workpiece in any suitable manner, such as forming a positive fit (e.g., retaining, clamping, passing through a locating pin, etc.). In the present embodiment, the structure and positioning principle of the positioning stage 11 are not limited.

The transport vehicle 14 is movably supported on the support frame 12, and the transport vehicle 14 is movable on the support frame 12 and the carrier 13 along a predetermined path. Preferably, the transportation cart 14 may include a driving device 141 and wheels 142, and the driving device 141 drives the wheels 142 to roll. The driving device 141 includes, but is not limited to, a motor, a gear transmission mechanism, and the like, and any device capable of providing power may be used as the driving device 141. The number of the wheels 142 may be four, and four wheels 142 are grouped in pairs, and each group of the wheels 142 is connected through a wheel axle to realize synchronous rotation. Of course, the number of wheels 142 is not limited thereto. The transport cart 14 has a gripping position (position when the gripper arms 15 grip the workpiece) and a release position (position when the gripper arms 15 release the workpiece). The gripping position may be on the support shelf 12 near the carrier 13 (outside the carrier 13, e.g., on the first support shelf 122), or may be on the carrier 13 (when the transport vehicle 14 travels onto the carrier 13); the release position may be on the carrier 13 (i.e., the workpiece is released by the mechanical gripper arms 15 when the carriage 14 is on the carrier 13), or may be on the support frame 12 near the positioning platform 11 (outside the carrier 13), or may be on the positioning platform 11. The carriage 14 can be moved from the holding frame 12 to the loading or positioning platform 11 during the movement from the gripping position to the release position. In this embodiment, the driving device 141 may assign a preset path to the wheel 142, i.e., the preset path is determined by the driving device 141; in other embodiments, the driving device 141 is only used for driving the wheel 142, and the preset path may be implemented by other guiding structures (including but not limited to a guide rail and a guide groove); and/or, the transporter 14 may also be free of wheels 142 and slide directly on the deck.

The mechanical gripper arms 15 are mounted on the transport carriage 14 and are movable with the transport carriage 14. The mechanical clamping arm 15 is used for clamping the workpiece from the loading rack 13 and releasing the workpiece to the positioning platform 11. When the transport vehicle 14 is located at the clamping position, the mechanical clamping arm 15 can clamp the workpiece on the loading rack 13 and carry the workpiece to travel to the positioning platform 11 along with the transport vehicle 14; when the transport carriage 14 reaches the release position, the gripper arms 15 can release the workpiece onto the positioning table 11.

In this embodiment, the operations of the transport vehicle 14, the mechanical arm 15, and the positioning table 11 can be controlled by corresponding logics. For example, the processing apparatus 10 may include a controller and a signal transmitter, and a signal receiver may be disposed on the transport cart 14 and/or the mechanical clamping arm 15, and the positioning platform, and the controller sends a signal to the signal receiver through the signal transmitter to control the transport cart 14 to travel, the mechanical clamping arm 15 to clamp and release the workpiece, and the positioning platform to position the workpiece.

In this embodiment, a carrier 13 capable of carrying a workpiece and a transport vehicle 14 capable of traveling along a preset path are installed in the support frame 12, a mechanical arm 15 capable of clamping and releasing the workpiece is installed on the transport vehicle 14, a positioning platform 11 is installed on one side of the carrier 13, the transport vehicle 14 drives the mechanical arm 15 to convey the clamped workpiece to the positioning platform 11, and the positioning platform 11 positions the workpiece so as to process the workpiece. Therefore, the machining equipment 10 can realize mechanical and automatic taking, transporting and positioning of workpieces, not only improves machining efficiency, but also can guarantee machining precision.

In one embodiment, as shown in fig. 1, the carrier 14 may be located on the support frame 12 and on opposite sides of the carrier frame 13 from the positioning platform 11 when the carrier 14 is in the gripping position. When the gripper arms 15 pick up the workpiece, the trolley 14 will start to travel from the support frame 12 to the loading bay 13 and approach the positioning platform 11 to finally reach the release position. It will be appreciated that the carriage 14 will not impact the workpiece as it moves, since the workpiece is already gripped. In this embodiment, the clamping position of the carrier vehicle 14 is arranged outside the material loading frame 13, so that the workpiece placing space of the material loading frame 13 is ensured to be unoccupied, and the collision between the carrier vehicle 14 and the workpiece on the material loading frame 13 is avoided. In other embodiments, the carrier 14 can be located on the carrier 13 when the carrier 14 is in the gripping position, in which case the workpiece is smaller in size and the workpiece and the carrier 14 can be carried on the carrier 13 at the same time. The utility model discloses an in the scheme, can press from both sides the concrete coordinate of getting the position according to the size determination of work piece.

In one embodiment, as shown in fig. 1, the positioning platform 11 is preferably connected to the supporting frame 12 and located at one side of the carrier frame 13. In the release position, the carriage 14 may rest partially on the carrier 13 and partially travel to the region of the support frame 12 between the positioning platform 11 and the carrier 13. For example, the second support frame 121 may have a second skid plate 17 laid thereon, the second skid plate 17 being connected between the positioning platform 11 and the carrier frame 13, and a portion of the transport vehicle 14 may run onto the second skid plate 17. In other embodiments, the transporter 14 may be located entirely on the carrier 13, or partially or entirely on the positioning platform 11 when the transporter 14 is in the release position. The utility model discloses an in the scheme, can confirm the specific coordinate of release position according to the size of work piece.

In one embodiment, the processing device 10 may further include a processing device 10, and the processing device 10 is adjacent to the positioning platform 11 and is used for processing the workpiece positioned on the positioning platform 11. Preferably, the processing device 10 may be a punching device for punching holes in a workpiece. After the machining device 10 finishes machining, the mechanical clamping arm 15 may clamp the workpiece from the positioning platform 11 to carry the workpiece along with the transport vehicle 14 to return to the clamping position, and release the workpiece onto the material carrying plate 132. Preferably, the carriage 14 returns the original path to the gripping position after releasing the workpiece onto the positioning table 11. After the workpiece is processed, the carriage 14 will move from the gripping position to the release position again to wait for the workpiece to be carried back. In this process, the positioning table 11 can release the positioning of the workpiece, so that the gripper arms 15 can grip the workpiece from the positioning table 11. Then, the transport cart 14 drives the gripper arms 15 to return from the release position to the gripping position, and the gripper arms 15 place the workpiece again on the carrier 13. In other embodiments, after releasing the workpiece onto the positioning platform 11, the transport vehicle 14 may remain stationary, and the operation of transporting the workpiece back is repeated after the machining is completed.

As shown in fig. 2, in one embodiment, the loading rack 13 may include a loading frame 131, and the loading frame 131 is installed in the supporting frame 12. The number of the material loading frames 131 may be any number (for example, 2). The loading frames 131 may be connected as a whole or designed separately. Correspondingly, the number of the transport carts 14 and the gripper arms 15 can be matched with the number of the loading frames 131, one loading frame 131 corresponds to one transport cart 14 and one gripper arm 15, and one gripper arm 15 only grips a workpiece in one loading frame 131. At least two material carrying plates 132 (for example, 10 layers) are installed in the material carrying frame 131, the at least two material carrying plates 132 are stacked at intervals, and each material carrying plate 132 can carry a workpiece. The material loading frame 131 can slide on the supporting frame 12 to drive any material loading plate 132 to move to a position corresponding to the mechanical clamping arm 15, so that the mechanical clamping arm 15 can clamp the workpiece on the material loading plate 132 corresponding thereto, or release the workpiece onto the corresponding material loading plate 132. After the workpiece on the previous material loading plate 132 is transferred, the material loading frame 131 can slide for a set distance, so that the next material loading plate 132 moves to correspond to the mechanical clamping arm 15, and the mechanical clamping arm 15 continues to clamp the workpiece on the material loading plate 132 or release the workpiece onto the material loading plate 132. The material carrying frame 131 capable of carrying multiple layers of workpieces is designed, the material carrying frame 131 can slide, the fixed mechanical clamping arm 15 can clamp the workpieces on different layers, and large-batch workpiece transfer is achieved. In other embodiments, such a design is not required.

As shown in fig. 4 and 5, in one embodiment, the support frame 12 may be provided with a screw mechanism and a slide rail 20. The screw 18 of the screw mechanism is parallel to the slide rail 20. The carriage 131 is connected to the nut 19 of the screw mechanism to move along the screw 18 following the nut 19. The loading frame 131 may further include a sliding block 133, and the sliding block 133 may be slidably disposed on the sliding rail 20 to slide along the sliding rail 20 along with the movement of the loading frame 131. In order to make the loading frame 131 slide smoothly, sliders 133 may be installed at each corner of the loading frame 131. The movement of the material loading frame 131 can be simply and reliably realized by using a screw mechanism; the arrangement of the sliding blocks 133 in cooperation with the sliding rails 20 can enhance the motion stability of the material loading frame 131. In other embodiments, other driving mechanisms/devices may be used to achieve the movement of the loading frame 131.

As shown in fig. 6, in one embodiment, the surface of the carrier plate 132 for carrying the workpiece may form a guide groove 132 a. The guide groove 132a may be integrally formed with the rest of the carrier plate 132, i.e., the guide groove 132a is formed in the carrier plate 132 through a grooving process; alternatively, as shown in fig. 7, the carrier plate 132 ' may include a first sub-plate 1321 ', a groove member 1322 ' and a second sub-plate 1323 ', the groove member 1322 ' being connected between the first sub-plate 1321 ' and the second sub-plate 1323 ', the groove member 1322 ' having the guide groove 132a, the cross section of the groove member 1322 ' having a groove shape. Accordingly, when the transport cart 14 moves on the carrier 13, a portion of the mechanical arm 15 may extend into the guide groove 132 a. The guide groove 132a guides the transport vehicle 14 by limiting the mechanical arm 15. The motion guide of the transport vehicle 14 is realized by the cooperation of the mechanical arm 15 and the guide groove 132a, the drive control of the transport vehicle 14 can be simplified by using a simple guide structure, and the design, manufacture and debugging costs are reduced. Further, when the first and second tie plates 16 and 17 are present, guide grooves may be provided in the first and/or second tie plates 16 and 17, and the guide grooves may be abutted against the guide grooves 132a of the material carrying plate 132, so that the mechanical arm 15 may extend into the guide grooves at the gripping and releasing positions, thereby guiding the transport vehicle 14 through the guide grooves over the entire predetermined path. It should be understood that the design of the guide groove in the present embodiment is not related to whether the material loading frame 131 is slidable, and therefore, the design of the guide groove is applicable to both the scheme in which the material loading frame 131 is slidable and the scheme in which the material loading frame 131 is fixed. In other embodiments, the design of the guide groove is not necessary.

As shown in fig. 3, in the above embodiments, the gripper arm 15 may include a first gripper arm 151 and a second gripper arm 152 which are spaced and opposite to each other, and the first gripper arm 151 may rotate relative to the second gripper arm 152 to close the gripper arm 15 for gripping a workpiece, or to open the gripper arm 15 for releasing a workpiece. Preferably, the first clamp arm 151 may be rotated while the second clamp arm 152 is fixed, to reduce the complexity of the driving design and improve the movement accuracy. When the transport vehicle 14 reaches the clamping position, the mechanical clamping arms 15 are closed to clamp the materials; when the transport carriage 14 reaches the release position, the gripper arms 15 are opened to release the material to the positioning platform 11. Accordingly, as shown in fig. 6 or fig. 7, when the transport cart 14 moves on the material loading rack 13 (e.g., on the material loading plate 132), the second clamping arm 152 can extend into the guiding slot 132a, and the guiding slot 132a can limit the second clamping arm 152 to guide the transport cart 14.

As shown in fig. 8 and 9, in the above embodiments, the positioning platform 11 may include a first clamping member 1141, a second clamping member 1142, a guiding member 113, a limiting member 111, and an abutting member 112.

The first clamping member 1141 and the second clamping member 1142 are adjacent to the carrier 13 (for example, the first clamping member 1141 and the second clamping member 1142 are both connected to the supporting frame 12 and located at one side of the carrier 13), the first clamping member 1141 and the second clamping member 1142 are arranged side by side at an interval, and a first gap 114a is formed between the first clamping member 1141 and the second clamping member 1142. The first clip 1141 can move away from or close to the second clip 1142 to change the width of the first gap 114 a. As the first gap 114a becomes narrower, the first clamping member 1141 and the second clamping member 1142 can clamp one positioning portion 102 on the workpiece (described further below). The movement pattern of the first clamping member 1141 may be translation. The second clip 1142 may be fixed. The first and second clamping members 1141 and 1142 may have a plate shape, and a surface size of the plate shape is determined to stably support the workpiece 100. Only the first clamping member 1141 can move to simplify the motion control and improve the motion precision, thereby being beneficial to the positioning precision. In other embodiments, first clip 1141 and second clip 1142 may each move toward or away from each other.

The guide 113 is located at an end of the first clamping member 1141 and the second clamping member 1142 facing away from the carrier frame 13. The guide member 113 is provided with a second slit 113a, and the second slit 113a is abutted with the second slit 113 a. The second slit 113a of the guide 113 may be used to guide another positioning portion 101 on the workpiece (to be described later). In the present embodiment, the guide 113 may be an integral member or a split member, and when the split member is used, the second slit 113a is a gap between different portions of the guide 113.

The limiting member 111 is disposed at an end of the second slit 113a away from the first slit 114a, and the limiting member 111 is used for limiting the workpiece 100. Specifically, the positioning portion 101 of the workpiece 100 located in the second gap 113a may abut against the limiting member 111, and the limiting member 111 limits the workpiece 100 through the abutting action of the positioning portion 101 (which will be described later). In this embodiment, the limiting member 111 may be substantially in a square shape, the limiting member 111 may be spliced with the guiding member 113, and a surface of the limiting member 111 may be opposite to an opening of one end of the second slit 113a far from the first slit 114 a. Preferably, the limiting member 111 may be embedded in the guide member 113, that is, an installation groove is formed in the guide member 113, the installation groove is communicated with the second gap 113a, and the limiting member 111 is installed in the installation groove. Of course, the structure and position design of the stopper 111 are not limited thereto.

The abutting member 112 is adjacent to the limiting member 111 and the second gap 113a, and is used for pressing the positioning portion 101 on the workpiece 100, which is located in the second gap 113a, so that the positioning portion abuts against the surface of the limiting member 111, and the workpiece 100 is limited. Specifically, the abutting member 112 can move into the second slot 113a and approach the limiting member 111. At this time, the abutting member 112 may contact the positioning portion 101 of the workpiece 100 in the second gap 113a and push the positioning portion to the limiting member 111 (meanwhile, the workpiece 100 also moves toward the limiting member 111). When the abutting member 112 reaches the predetermined position, the abutting member 112 presses the positioning portion 101 against the limiting member 111, so that the positioning portion 101 is stably clamped between the limiting member 111 and the abutting member 112 (facilitating the processing of the workpiece 100). Of course, the abutting member 112 may also move reversely to gradually exit the second gap 113a and move away from the limiting member 111, so as to release the positioning portion 101, and facilitate the retrieving of the workpiece 100.

In this embodiment, when the transport cart 14 reaches the release position, the mechanical arm 15 can release the workpiece onto the positioning platform 11, so that the workpiece is supported on the first clamping member 1141, the second clamping member 1142 and the guide member 113, and the two positioning portions 102 and 101 respectively extend into the first gap 114a and the second gap 113 a. At this time, the abutting member 112 moves into the second gap 113a and approaches the limiting member 111, so as to clamp one of the positioning portions 101 between the limiting member 111 and the abutting member 112; the first clamping member 1141 moves closer to the second clamping member 1142 to narrow the first gap 114a to clamp the other positioning portion 102. Since both the positioning portions 102, 101 are restricted, the workpiece is positioned on the positioning table 11. In this embodiment, the action of the abutting member 112 approaching the limiting member 111 and clamping one positioning portion 101 together with the limiting member 111 and the action of the first clamping member 1141 approaching the second clamping member 1142 and clamping the other positioning portion 102 may start and end at substantially the same time. In this embodiment, the workpiece 100 can be ensured to accurately reach the processing position by the matching design of the abutting member 112 and the limiting member 111; because the workpiece 100 is limited by two points, the workpiece 100 does not shake, and therefore the workpiece 100 can be stably loaded on the first clamping member 1141, the second clamping member 1142 and the guide member 113, and the workpiece 100 can be reliably positioned, thereby ensuring the machining precision.

As shown in fig. 10, in one embodiment, the width of the portion of the first slit 114a adjacent to the second slit 113a is greater than the width of the remaining portion of the first slit 114 a; and/or the width of the portion of the second slit 113a adjacent to the first slit 114a is greater than the width of the remaining portion of the second slit 113 a. That is, at the intersection of the first slit 114a and the second slit 113a, the slit widths of both are larger, and the slit widths of the remaining positions are smaller. Preferably, the slit width may be gradually changed in a wider area of the first slit 114a and the second slit 113 a. The variable slit width design of the first slit 114a and the second slit 113a facilitates the positioning portion 101 on the workpiece 100 to enter the second slit 113a from the first slit 114a or retreat from the second slit 113a into the first slit 114a more easily and without obstruction. In other embodiments, the slot width of the first slot 114a and/or the second slot 113a may be constant.
