The PIN pressing device provided by the embodiment of the invention is installed on the rack 600 and is used for performing PIN pressing operation on the processing plate 400, wherein the processing plate 400 comprises a first plate and a second plate covered on the first plate, a positioning part is convexly arranged on one side of the first plate close to the second plate, and the PIN pressing device comprises a PIN pressing component 300. The PIN pressing assembly 300 includes a pressing head 310 and a first driving member 320; the first driving member 320 is installed on the frame 600, and when the processed plate 400 is in a fixed state, the pressing head 310 can move close to the second plate along the thickness direction of the second plate under the driving of the first driving member 320, so that the second plate is pressed onto the first plate on the periphery of the positioning member.

When the PIN pressing device provided by the invention is installed on a PCB drilling machine and performs PIN pressing operation on a circuit board, the processing plate 400 is loaded and fixed through the workbench assembly 100, and when the processing plate 400 is in a fixed state, the first driving piece 320 drives the pressing head 310, so that the pressing head 310 moves close to the second plate along the thickness direction of the second plate, the second plate is pressed on the first plate on the periphery of the positioning piece, and the PIN pressing operation on the processing plate 400 is completed. Because this pressure PIN device is through the motion of first driving piece 320 drive ram 310, and then presses PIN operation to processing panel 400, therefore do not need the mode of artifical beating to press PIN operation to processing panel 400, manual operation's step has been reduced, manual labor intensity has been reduced for whole pressure PIN operation process can become an assembly line, has improved the degree of automation and the production efficiency of PCB drilling machine, the utilization rate of PCB drilling machine is higher, economic benefits is also better. In one embodiment, the first driving member 320 is an air cylinder, but the first driving member 320 may be a motor in other embodiments.

It should be noted that, when the first plate needs to be drilled, a second plate for protection is disposed above the first plate to avoid unnecessary damage to the machined surface of the first plate. However, since the positioning member is protruded from a side of the first plate close to the second plate, a larger gap is formed between the positioning member of the first plate and the second plate. The clearance weakens the protection measure of the first plate by the second plate, and in the drilling processing operation process, cutting chips can easily enter between the first plate and the second plate, so that secondary damage such as scraping and the like is caused to the processing surface of the first plate. Therefore, before the first plate is drilled, the gap between the positioning part of the first plate and the second plate needs to be reduced. The operation of reducing the gap between the positioning member of the first plate and the second plate is referred to as PIN pressing operation of the worked plate 400.

In some embodiments, the processing Board 400 is a Circuit Board, and may specifically be a Printed Circuit Board or a Printed Circuit Board, such as a PCB (Printed Circuit Board) or an FPC (Flexible Printed Circuit Board), and of course, in other embodiments, the processing Board 400 may be other metal Board or ceramic Board, which is not limited in this respect, and may be selected according to the processing requirement.

In one specific embodiment, the processing board 400 is a PCB board to be processed, such that the first board is a copper clad board and the second board is an aluminum board. When the copper-clad plate needs to be drilled, the aluminum plate can cover the upper part of the processing surface of the copper-clad plate and protect the processing surface of the copper-clad plate. Because the positioning piece is convexly arranged on one side of the copper-clad plate close to the aluminum plate, a larger gap is formed between the positioning piece of the copper-clad plate and the aluminum plate. Therefore, PIN pressing operation is carried out on the positioning part of the copper-clad plate and the aluminum plate through the PIN pressing component 300, so that the gap between the positioning part of the copper-clad plate and the aluminum plate is reduced, the copper-clad plate is better in protection effect of the aluminum plate to the aluminum plate in the subsequent drilling operation process, cutting chips can be prevented from entering between the aluminum plate and the copper-clad plate, and secondary damage such as scratching is caused to the processing surface of the copper-clad plate. In one particular embodiment, the locating member is a PIN, also known as a PIN. Of course, in other embodiments, the positioning element may be a screw, a stud, or other positioning elements.

Since the processing plate 400 is provided with at least two positioning members along the length direction thereof, PIN pressing operation is required to be performed on at least two positioning members of the processing plate 400. Referring to fig. 12, the PIN pressing device according to an embodiment of the present invention further includes a workbench assembly 100 and a first moving assembly 510. The worktable assembly 100 is used for being mounted on the frame 600, and the worktable assembly 100 is used for bearing and fixing the processing plate 400; the first moving assembly 510 is installed on the workbench assembly 100, and the first moving assembly 510 is connected with the workbench assembly 100 and can drive the workbench assembly 100 to move along the length direction of the workbench assembly 100; the positioning element can be driven by the workbench assembly 100 to move to a first preset position below the pressing head 310, and the first preset position is a position where the positioning element can be accommodated in the accommodating cavity along the height direction of the positioning element.

It should be noted that, after the processing plate 400 is fixed to the workbench assembly 100 by the pressing assembly 200, the processing plate 400 is not prone to shake relative to the bearing surface of the workbench assembly 100, so that the PIN pressing assembly 300 can perform PIN pressing operation on the processing plate 400 more safely. Of course, in other embodiments, after PIN pressing operation is completed on processed board 400 by PIN pressing assembly 300, pressing operation is performed on processed board 400 by pressing assembly 200, which only needs to ensure that processed board 400 is in a pressed state when drilling operation is needed after PIN pressing operation on processed board 400 is completed.

Referring to fig. 8 and 9, a pressing assembly 200 of a PIN pressing device according to an embodiment of the present invention includes a mushroom head pressing plate 210 and a driving group 220; the driving group 220 is arranged on the workbench assembly 100, the mushroom head pressing plate 210 is connected with the power output end of the driving group 220, and the driving group 220 can drive the mushroom head pressing plate 210 to move close to or away from the workbench assembly 100; when the mushroom head pressing plate 210 moves close to the table assembly 100, the work sheet 400 can be fixed to the table assembly 100 by the mushroom head pressing plate 210.

The driving group 220 drives the mushroom head pressing plate 210 to move close to or away from the workbench assembly 100, so that the processing plate 400 can be fixed on the workbench assembly 100 by the mushroom head pressing plate 210, and the processing method is very simple and convenient. There is no need to secure the work sheet 400 to the table assembly 100 by the bonding action of the disposable masking tape.

In one embodiment, the work table assembly 100 includes a pressure bearing plate 110, the pressure bearing plate 110 is used for bearing the work sheet 400, and the mushroom head pressing plate 210 passes through the pressure bearing plate 110 and can move toward or away from the pressure bearing plate 110, thereby fixing and separating the work sheet 400 with respect to the pressure bearing plate 110. In one specific embodiment, the driving group 220 is a cylinder disposed along the length direction of the mushroom head pressing plate 210, but in other embodiments, the driving group 220 may be a linear motor disposed along the length direction of the mushroom head pressing plate 210.

Referring to fig. 8 and 9, a mushroom head pressing plate 210 of a PIN pressing apparatus according to an embodiment of the present invention includes a mushroom pressing head 211 and a connection cylinder 212 connected to each other. One side of the connecting cylinder 212 departing from the mushroom pressing head 211 is connected with the power output end of the driving group 220, the diameter of the mushroom pressing head 211 is larger than that of the connecting cylinder 212, and the mushroom pressing head 211 can abut against and press one side of the second plate departing from the first plate under the driving of the driving group 220.

By arranging the mushroom head pressing plate 210 to have the mushroom indenter 211 and the connection cylinder 212 connected to each other, and the diameter of the mushroom indenter 211 is larger than that of the connection cylinder 212, the mushroom head pressing plate 210 forms an umbrella-shaped pressing member. The umbrella-shaped pressing member can clamp the work sheet 400 between the mushroom press head 211 and the pressure bearing plate 110. When the driving unit 220 drives the mushroom head pressing plate 210 to move close to the processing plate 400, the connecting column 212 similar to the umbrella handle structure does not contact with the processing plate, so that the friction force between the moving processes is reduced, and the movement is smooth until the mushroom pressing head 211 similar to the umbrella cover structure is abutted against the second plate and presses the second plate onto the first plate.

Referring to fig. 8 and 9, a driving unit 220 of the PIN pressing device according to an embodiment of the present invention includes a second driving member 221, a sliding block 222, a V-shaped rod 223, and a hinge shaft 224. The second driving element 221 is mounted on the workbench assembly 100, the sliding block 222 is slidably connected to the outer wall of the second driving element 221, one end of the V-shaped rod 223 is connected with the power output end of the second driving element 221, the other end of the V-shaped rod 223 is connected with one end of the connecting column 212, which is far away from the mushroom pressing head 211, and the V-shaped rod 223 is rotatably connected with the sliding block 222 through a hinge shaft 224; the second driving member 221 can drive the V-shaped rod 223 to rotate around the rotation axis of the hinge shaft 224, so as to drive the mushroom head pressing plate 210 to move closer to or away from the worktable assembly 100 along the height direction of the worktable assembly 100.

Referring to fig. 9, when it is required to fix the work sheet 400 to the pressure bearing plate 110, the mushroom head pressing plate 210 is required to move closer to the pressure bearing plate 110. At this time, the second driving member 221 drives the V-shaped rod 223 to rotate counterclockwise around the rotation axis of the hinge shaft 224, so that the end of the V-shaped rod 223 connected to the connecting cylinder 212 slightly rotates counterclockwise and moves downward. Since the mushroom head pressing plate 210 performs a circular motion with a radius from the rotational axis of the hinge shaft 224 to the end of the connection cylinder 212 to which the V-shaped bar 223 is connected during the motion, when the end of the V-shaped bar 223 connected to the mushroom head pressing plate 210 moves downward, the slider 222 must slightly move in the horizontal rightward direction of fig. 9 to perform the circular motion. Thus, the approaching movement of the mushroom head pressing plate 210 with respect to the bearing plate 110 is finally achieved by the combination of the counterclockwise rotation of the V-shaped bar 223 and the horizontal rightward movement of the slider 222. When the fixing between the processing plate 400 and the bearing plate 110 needs to be released, the second driving member 221 is needed to drive the V-shaped rod 223 to rotate clockwise around the rotation axis of the hinge shaft 224, and the movement process is opposite to the above, and thus, the description thereof is omitted.

Referring to fig. 9, the V-shaped bar 223 of the PIN pressing device according to an embodiment of the present invention includes a first bar 2231 and a second bar 2232 connected to each other, and the first bar 2231 and the second bar 2232 are disposed at an angle; an end of the first link 2231 away from the second link 2232 is connected to a power output end of the second driver 221, an end of the second link 2232 away from the first link 2231 is connected to the connecting cylinder 212, and a connecting portion between the first link 2231 and the second link 2232 is rotatably connected to the hinge shaft 224.

Since the V-shaped bar 223 includes the first link 2231 and the second link 2232 connected to each other, and the first link 2231 and the second link 2232 are disposed at an angle, the length of the first link 2231 is less than the length of the second link 2232. Therefore, when the power output end of the second driving member 221 drives the first link 2231 to move in the horizontal direction, a smaller moving distance of the first link 2231 in the horizontal direction can drive a larger moving distance of the second link 2232 in the vertical direction away from one end of the first link 2231.

Referring to fig. 8 and 9, in one specific embodiment, the driving set 220 further includes a shaft joint 227, and the first link 2231 is connected to the power output end of the second driving member 221 through the shaft joint 227.

In one specific embodiment, the second moving member 520 is an air cylinder, but in other embodiments, the second moving member 520 can also be a motor.

Referring to fig. 1 to 7, in the PIN pressing apparatus according to an embodiment of the present invention, the number of the pressing members 200 is plural, the plural pressing members 200 are spaced apart in the length direction and the width direction of the processed board 400, and the mushroom press head 211 of each pressing member 200 is provided with a sensor. When every processing panel 400 need be fixed on the bearing plate 110 of workstation subassembly 100, compress tightly the effect through a plurality of joint of compressing tightly subassembly 200 for processing panel 400 is higher on bearing plate 110 fixed stability, and then makes and presses PIN subassembly 300 when pressing PIN operation to processing panel 400, and processing panel 400 is difficult for taking place to remove, and the accuracy of pressing PIN operation is higher.

In one specific embodiment, pressing assembly 200 includes a front pressing assembly 200 and a rear pressing assembly 200, and each work sheet 400 is pressed together by two front pressing assemblies 200 and two rear pressing assemblies 200. The four pressing assemblies 200 press the four corners of the processing board 400 together, so that the processing board 400 is fixed on the bearing plate 110 with high stability.

Specifically, the sliding block 222 of the front pressing assembly 200 slides on the bearing plate 110 along the second sliding groove 112, the sliding block 222 of the rear pressing assembly 200 slides on the bearing plate 110 along the first sliding groove 111, and the length of the first sliding groove 111 is greater than that of the second sliding groove 112. When the processed plate 400 needs to be subjected to plate loading operation from one side of the rear pressing assembly 200 and fixed to the bearing plate 110, at this time, the driving group 220 in the rear pressing assembly 200 drives the rear mushroom head pressing plate 210 to descend, so that the rear mushroom head pressing plate 210 can be level with the height direction of the upper surface of the bearing plate 110 or slightly lower than the upper surface of the bearing plate 110, and the processed plate 400 is convenient to move on the bearing plate 110; the driving group 220 in the front pressing assembly 200 drives the front mushroom head pressing plate 210 to ascend, so that the maximum moving distance of the processed plate 400 is limited conveniently; when the processed plate material 400 is transferred to the predetermined position on the pressure bearing plate 110, the second moving assembly 520 drives the rear pressing assembly 200 to move along the first sliding groove 111 along the side away from the processed plate material 400, so that the rear mushroom head pressing plate 210 can be moved out from the bottom of the processed plate material 400 and can be lifted along the upper surface of the pressure bearing plate 110. At this time, the driving unit 220 drives the front mushroom head pressing plate 210 and the rear mushroom head pressing plate 210 to move closer to the bearing plate 110, so that the front mushroom head pressing plate 210 and the rear mushroom head pressing plate 210 abut against the processing plate 400, thereby fixing the processing plate 400 to the bearing plate 110. When it is necessary to release the fixing of the work sheet 400 with respect to the bearing plate 110, the movement process is reversed, and thus, the description thereof is omitted.

The second moving assembly 520 drives the pressing assembly 200 to move along the length direction of the processed plate 400, and the driving assembly 220 drives the mushroom head pressing plate 210 to move along the thickness direction (height direction) of the processed plate 400, so that the front pressing assembly 200 and the rear pressing assembly 200 can press and fix the processed plate 400 to the preset position of the pressure bearing plate 110 under the cooperation of the two.

In one embodiment, the mushroom press head 211, the connecting cylinder 212, the guide rod 225, the V-shaped rod 223, and the shaft connector 227 are made of a conductive material, such as iron, aluminum, or copper. Since the mushroom indenter 211 is fitted with a sensor. When compressing tightly the second panel through compressing tightly subassembly 200, because the second panel is aluminum plate, therefore can transmit the signal of telecommunication of sensor, the transmission path of the signal of telecommunication of sensor this moment is: mushroom ram 211-connecting cylinder 212-guide rod 225-V-shaped rod 223-pivot joint 227. And the lead wires connected to the controller are connected to the junction of the shaft joint 227 and the second driver 221.

Whether the four mushroom head pressing plates 210 fix the work sheet 400 to the pressure bearing plate 110 is determined by judging the presence or absence of the three loop electric signals. For example, when one of the loop signals is missing and the other two loop signals are normal, it indicates that the mushroom head pressing plate 210 at the missing loop signal position does not fix the processed plate 400 well. When all three loop signals are absent, two possibilities exist, one is that the mushroom head pressing plate 210 connected with the ground wire does not fix the processed plate 400 well; the other is that the mushroom head pressing plates 210 at the other three places do not fix the processed plate 400 well. The fixing condition of the processing plate 400 relative to the bearing plate 110 can be preliminarily judged according to the loop signal condition transmitted by the sensor, and the method is very simple and convenient.

The PIN pressing device provided by the invention transmits the loop electric signal condition of the sensor through the connecting piece made of the conductive material, so that the whole structure does not need to be connected with redundant electric wires, and the PIN pressing device is more compact and safer. Of course, in other embodiments, the transmission may be directly performed through a connecting wire, which is not limited.
