Description

Technical Field

[0001] The utility model relates to the technical field of PCB processing, in particular to a material taking device for quickly taking out a protective cover of a PCB board. Background Art

[0002] PCB production usually involves making multiple small-sized PCBs on a large plate at the same time, and then sending them to a panel splitter to be cut into PCBs one by one. When making large PCBs, corresponding electronic components need to be set, and when setting connector plugs or sockets, the connector plugs and sockets will have protective covers. The loading robot absorbs the protective cover to realize automatic loading and welding of the connector plugs or sockets on the PCB.

[0003] The inventor discovered during actual production operations that, during subsequent shipment, the protective cover needs to be removed from the connector plug or socket before the PCB board can be packaged; however, the operator needs to remove the protective cover of the PCB board one by one. This operation method is not only time-consuming and labor-intensive, which seriously affects the packaging efficiency, but also easily causes scratches on the surface of the connector plug or socket.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0037] Please also read Figures 1 to 8Now, a material extraction device for quickly extracting a PCB board protective cover provided in an embodiment of the present application is described. The material extraction device for quickly extracting a PCB board protective cover comprises: a first base 10, a first movable plate 20 and a second movable plate 30.

[0038] The first movable plate 20 and the second movable plate 30 are both installed on the first base 10. The first base 10, the first movable plate 20 and the second movable plate 30 are stacked in sequence from bottom to top. The first movable plate 20 can move up and down relative to the first base 10, and the second movable plate 30 can move left and right relative to the first base 10. The first base 10 is provided with a first cylinder 11 and a first switch 12, and the first switch 12 is connected to the first cylinder 11 by signal. The telescopic rod 111 of the first cylinder 11 is connected to the first movable plate 20, and the first movable plate 20 is provided with a plurality of cover-pulling protrusions 21 for pulling out the protective cover 50. The second movable plate 30 can be installed on the first base 10 to move up and down, and the second movable plate 30 is used to carry the PCB board 40. After the second movable plate 30 is displaced to the left or right, the protective cover 50 enters the position of the cover-pulling protrusion 21 and simultaneously triggers the first switch 12, so that the first movable plate 20 moves down to pull out the protective cover 50.

[0039] Specifically, by causing the second movable plate 30 to move leftward or rightward, the protective cover 50 enters the position of the cover-pulling protrusion 21 and simultaneously triggers the first switch 12, so that the first movable plate 20 moves downward to pull out the protective cover 50, and there is no need to manually pull out the protective cover 50. This not only improves the packaging efficiency of the PCB board 40, but also ensures that the plug or socket of the connector 41 is not scratched when the protective cover 50 is pulled out, thereby reducing the generation of scratches and improving the yield rate of the product.

Therefore, when the first switch 12 is triggered, the telescopic rod 111 of the first cylinder 11 retracts downward to drive the first movable plate 20 to move downward, so that the protective covers 50 of the sockets or plugs of the multiple connectors 41 of the PCB board 40 can be pulled out vertically downward at one time; on the one hand, the efficiency of pulling out the cover can be improved; on the other hand, it can ensure that the housing of the connector 41 will not be scratched when the protective cover 50 is pulled out.

[0041] More specifically, the first movable plate 20 is provided with first guide posts 22 at four corners of the lower surface, and the first base 10 is provided with first guide holes 13 for inserting the first guide posts 22, and the first guide holes 13 penetrate the upper and lower surfaces of the first base 10. Such a structure can improve the reliability of the first movable plate 20 when it moves up and down, and is not prone to shaking left and right, and further ensures that the housing of the connector 41 will not be scratched when the protective cover 50 is removed.

[0042] In other embodiments of the present application, the first base 10 is provided with a first avoidance opening 101 penetrating the upper and lower surfaces thereof, the first movable plate 20 is provided with a second avoidance opening 201 penetrating the upper and lower surfaces thereof, the second movable plate 30 is provided with a third avoidance opening 301 penetrating the upper and lower surfaces thereof, the first avoidance opening 101, the second avoidance opening 201 and the third avoidance opening 301 are coaxially arranged, and the cover extraction protrusion 21 is arranged at the position of the second avoidance opening 201. A collection box is installed below the first base 10, and the extracted protective cover 50 can be dropped from the third avoidance opening 301 through the second avoidance opening 201 and the first avoidance opening 101 in sequence into the collection box to complete the collection of the protective cover 50.

[0043] Specifically, the second avoidance opening 201 is provided with a plurality of first support ridges 202 arranged at intervals from left to right, and every two first support ridges 202 form a group, and each group of support ridges 202 is provided with a plurality of cover-pulling protrusions 21, and the plurality of cover-pulling protrusions 21 are arranged at intervals from front to back. The cover-pulling protrusions 21 include two inverted "L"-shaped protrusions 211 arranged at intervals from front to back, and every two inverted "L"-shaped protrusions 211 arranged at intervals form a cover-pulling area 212 for inserting the protective cover 50.

[0044] In some other embodiments of the present application, the upper surface of the first base 10 is provided with a first guide protrusion 14, and the lower surface of the second movable plate 30 is provided with a first guide groove 31 adapted to be installed with the first guide protrusion 14. A first spring 32 for providing elastic force for the second movable plate 30 is also included, one end of the first spring 32 abuts against the first guide protrusion 14, and the other end of the first spring 32 abuts against the first guide groove 31. A first positioning column 15 for limiting the displacement of the second movable plate 30 is provided on the right side of the first base 10, and the second movable plate 30 can abut against the first positioning column 15 when it moves to the right.

[0045] Preferably, the first switch 12 is installed on the left side of the upper surface of the first base 10, and the first trigger rod 34 is provided on the left side of the lower surface of the second movable plate 30. When the second movable plate 30 does not move to the left, the first switch 12 and the first trigger rod 34 are arranged at a left-right interval; the second movable plate 30 moves to the left into position, the first trigger rod 34 abuts against the first switch 12, and controls the first cylinder 11 to retract downward, so as to drive the first movable plate 20 to move downward, thereby completing the operation of pulling out the protective cover 50.

[0046] Please also read Figures 6 to 8 The working principle of a material extraction device for quickly extracting the protective cover 50 of the PCB board 40 provided by the present application is described in detail as follows:

[0047] First, place the PCB board 40 on the upper surface of the second movable plate 30, preferably with the left side of the PCB board 40 against the two first positioning protrusions 33; at this time, each connector 41 plug or socket of each PCB board 40 faces one side of the third avoidance opening 301, and each connector 41 plug or socket is located on the right side of each cover removal protrusion 21;

[0048] Then, the second movable plate 30 is pushed to move leftward, so that the first trigger rod 34 abuts against the first switch 12, and the first switch 12 then controls the first cylinder 11 to retract downward, so as to drive the first movable plate 20 to move downward and pull out the protective cover 50 of the connector 41 plug or socket vertically downward;

[0049] Furthermore, the force applied to the second movable plate 30 is released, and the first spring 32 provides elastic force to move the second movable plate 30 to the right to complete the reset, and the first cylinder 11 then extends upward to complete the reset;

[0050] At this time, the PCB board 40 can be removed.
