In the practical application scene, current nailing device is when the bolt nail, directly squeezes into the pin hole with the pin, consequently squeezes into the in-process of pin, probably has the crooked condition of pin, influences the insertion accuracy of pin, and then influences the follow-up location effect to the PCB board. In addition, the skew insertion of the pin also causes inconvenience to the pin pulling operation, thereby affecting the pin pulling efficiency in order to solve the above technical problems, and then the inventive concept of the present application will be specifically explained by the following embodiments.

FIG. 2 is a schematic structural view of a nailing device according to an embodiment of the present invention; fig. 3 is a partial schematic view of the nailing device of fig. 2. As shown in fig. 2 and 3, a nailing device according to an embodiment of the present invention includes a holding member 110, a first pressing part 121, and a second pressing part 122; a first stamping part 121 is arranged above the clamping part 110, and the first stamping part 121 is used for inserting the workpiece into the mounting hole of the processing table 300 to a first preset depth; the second stamping part 122 is arranged between the first stamping part 121 and the clamping part 110, the clamping part 110 is opened relative to the workpiece, and the second stamping part 122 is used for inserting the workpiece from a first preset depth to a second preset depth; the first preset depth and the second preset depth are both the lengths of the workpieces inserted into the mounting holes.

In the nailing device, when a workpiece needs to be inserted into the mounting hole in the processing table 300, the workpiece may be a pin, and in an actual application scene, for example, when a pin needs to be inserted into a mounting hole reserved on the processing table, the workpiece is clamped by the clamping part 110 and is positioned above the corresponding mounting hole; next, the first stamping 121 is actuated so that the workpiece is driven into the mounting hole to a first predetermined depth, so that the workpiece can stand in the mounting hole. The clamping member 110 is then opened relative to the workpiece and the second punch 122 is actuated to drive the workpiece into the mounting hole to a second predetermined depth, i.e., the workpiece contacts the bottom wall of the mounting hole. In the action process of the first stamping part 121, the clamping part 110 always provides clamping force for the workpiece, so that the clamping part 110 provides supporting force for two radial sides of the workpiece, the workpiece is prevented from being inclined, and the workpiece is ensured to be vertically inserted into the mounting hole. Meanwhile, in the process of the action of the second stamping part 122, the clamping part 110 is opened relative to the workpiece, so that the interference on the driving operation of the workpiece is avoided, and the workpiece is ensured to be completely driven into the mounting hole. Moreover, because the workpiece is vertically inserted into the mounting hole, the operation difficulty of subsequently pulling the workpiece can be reduced, and the efficiency of pulling and inserting the workpiece is ensured. That is to say, through the degree of automation that improves plug efficiency and plug operation, can make the plug effect more stable, reduce the plug fault rate. For example, when the total length of the workpiece is 10mm, the first preset depth is 3mm, and the second preset depth is 7mm, the length of the workpiece inserted into the mounting hole is 3mm when the first stamping part 121 moves; when the second pressing part 122 is actuated, the length of the workpiece inserted into the mounting hole is 7 mm.

In addition, in the process of the action of the first stamping part, on the premise of meeting the clamping requirement, the clamping part 110 is opened for a certain distance so as to reduce the clamping force of the clamping part 110, so that the friction force between the workpiece and the clamping part 110 is reduced, the acting force required to be overcome when the workpiece is driven into the mounting hole is reduced, the impact force required by driving the workpiece is reduced, and the stamping efficiency is improved.

As shown in fig. 2 or fig. 3, in an embodiment, the first stamping 121 and the second stamping 122 may be configured to include a cylinder and a piston rod, and an end of the piston rod facing away from the clamping member 110 is slidably connected to the cylinder, so that when the piston rod is lowered relative to the clamping member 110, the piston rod can act on the workpiece clamped by the clamping member 110, so as to insert the workpiece into the mounting hole. The first stamping part 121 and the second stamping part 122 may be specifically impact cylinders, and have many characteristics of strong impact force, high speed, small air consumption and the like. The impact function is realized by increasing the cylinder diameter, weighting the impact piston rod, reducing the friction coefficient of the cylinder wall and the like, and the service life of the impact cylinder can be prolonged while the impact force is increased.

In an alternative embodiment, as shown in fig. 2, the clamping member 110 comprises a first clamping driving member 111 and a clamping jaw 113 connected to the first clamping driving member 111, the workpiece has a first clamping position for clamping by the clamping jaw 113, the first clamping position is located between a first predetermined depth and a second predetermined depth, and when the workpiece is inserted into the mounting hole to the first predetermined depth, the first clamping driving member 111 drives the clamping jaw 113 to open for a first predetermined distance. That is, the clamping jaw 113 is clamped on the upper half section of the workpiece, and the first stamping part 121 acts on the workpiece, so that the workpiece moves downwards relative to the clamping jaw 113 and is driven into the mounting hole; after driving to the first predetermined depth, the jaws 113 are opened. When the first clamping driving member 111 is actuated, the plurality of clamping jaws 113 are moved in a direction to approach each other or move away from each other. The first predetermined distance is the maximum travel of the first clamp drive 111 to drive the jaws 113 open. After the jaws 113 are opened a first predetermined distance, the jaws 113 are lowered to enclose the end of the workpiece, and then the jaws 113 are closed to clamp the workpiece. The clamping jaw 113 is controlled to open and close through the first clamping driving piece 111, so that the workpiece can be clamped conveniently, and the clamping is convenient. Furthermore, an elastic piece capable of slowing down the collision between the clamping jaw 113 and the workpiece is arranged between the clamping jaw 113 and the clamping driving piece, so that the service life of the clamping part 110 is prolonged. The opposite sides of the two clamping jaws 113 are provided with clamping pieces to increase the friction force between the clamping jaws 113 and the workpiece, so that the anti-skid effect is achieved, the product clamping is more stable, and the workpiece is prevented from falling off in the clamping process. The first clamp driving member 111 may be embodied as a cylinder.

With continued reference to fig. 2, in another embodiment, the clamping member 110 further includes a second clamping driving member 112 connected to the clamping jaw 113, and the second clamping driving member 112 is used for driving the clamping jaw 113 to open by a second predetermined distance. The second predetermined distance is the maximum distance that the second clamping driving member 112 drives the clamping jaw 113 to open, and the second predetermined distance is different from the first predetermined distance. Thus, the stroke of the clamping jaw 113 can be adjusted according to the size of the workpiece, and the clamping jaw 113 with different sizes does not need to be replaced. For example, the first preset distance is 5mm, and the second preset distance is 10 mm; when the size of the workpiece is larger than 5mm, the second clamping driving piece 112 acts, and the clamping jaw 113 is opened by 10 mm; when the size of the workpiece is less than 5mm, the first clamp driving member 111 is actuated, and the clamp jaws 113 are opened by 5 mm. The opening stroke of the clamping jaw 113 is adjusted to adapt to clamping of workpieces with different sizes, and the workpieces are clamped quickly. In addition, the number of strokes of the jaws 113 can be increased by increasing the number of gripping drives to accommodate the actual gripping requirements.

In one embodiment, as shown in fig. 2, the nailing device further comprises a lifting member 130, and the holding member 110 is connected to the lifting member 130 such that the holding member 110 moves the workpiece closer to and farther from the mounting hole by the lifting member 130. In this manner, when it is necessary to pull out a workpiece from the mounting hole in the processing table 300, the lifting member 130 lowers the gripping member 110 to a certain height so that the gripping member 110 can grip the workpiece; after the clamping member 110 clamps the workpiece, the lifting member 130 drives the clamping member 110 to lift, thereby pulling out the workpiece on the machining table 300 from the mounting hole.

In the above embodiment, since the workpiece and the mounting hole are tightly fitted, when the clamping force or the pulling force for pulling out the workpiece is smaller than the acting force between the workpiece and the mounting hole, the workpiece may not be pulled out from the mounting hole. When the tension is too large, the stability of the connection between the processing table 300 and the frame is affected. Therefore, in order to solve the above problem, a grip sensor may be provided on the grip 113 to detect whether the workpiece is successfully pulled out. The grip sensor will send a signal when the jaws 113 are in the closed position. The clamping sensor is detected before and after the lifting part 130 is lifted, if the clamping sensor is triggered, the clamping jaw 113 is in a closed state, namely the clamping jaw 113 does not clamp the workpiece, and the workpiece is not pulled out from the mounting hole, the lifting part 130 is lowered again to perform the second workpiece pulling operation. If the workpiece is still failed to be pulled out for the second time, the position of the workpiece is recorded, and the workpiece is pulled out through manual operation subsequently.

With continued reference to fig. 2, in yet another embodiment, the nailing device further comprises a pressing plate assembly 150, wherein the pressing plate assembly 150 comprises a second lifting driving member and a pressing plate connected to the second lifting driving member; when the first lifting/lowering driving unit drives the clamping unit 110 to ascend, the second lifting/lowering driving unit drives the platen to descend with respect to the processing table 300, so that the platen is pressed against the processing table 300. Thus, when the lifting member 130 drives the clamping member 110 to move upwards to pull out the workpiece, the second lifting driving member drives the pressing plate to abut against the processing table 300, so that the processing table 300 is pulled and simultaneously receives downward pressure given by the pressing plate, the surface stress balance of the processing table 300 is ensured, the connection stability between the processing table 300 and the rack is further ensured, and the positioning effect of the PCB is ensured. The pressing plate has a larger pressing area, and the pressing force of the pressing plate is ensured. The second lifting driving piece can be a second air cylinder, and the second air cylinder is controlled by an external air pump, so that the vertical movement of the pressing plate is controlled, and compared with an electromechanical structure, the pneumatic control device has the advantages of safety and stability.

In one embodiment, the pressure plate assembly 150 further includes a connecting plate connected to a side of the pressure plate facing the second lift driving member, and an elastic member connected between the connecting plate and the pressure plate. The connecting plate, the elastic piece and the pressing plate are sequentially connected from top to bottom. Through setting up the elastic component, can play the cushioning effect when the clamp plate pushes down, avoid taking place the rigidity collision between clamp plate and the workstation, cause the clamp plate to damage, improve the life of clamp plate. Through setting up the connecting plate, improve the contact stability of second lift driving piece and elastic component. Through connecting plate and the abundant contact of elastic component, when guaranteeing that second lift driving piece descends, the pressure of applying can be through the connecting plate and act on the elastic component, guarantees the stability of elastic buffer.

In another embodiment, the pressing plate assembly 150 further comprises a reset member, one end of the reset member is connected to the elastic member, and the other end of the reset member is connected to the pressing plate; the reset piece is used for applying reset force far away from the machining table 300 to the pressing plate, and the reset force of the reset piece is larger than the elastic force of the elastic piece. The restoring member is in a stretched state when the pressing plate presses down the processing table 300. Through the reset force of the reset piece, after the pressing force is cancelled, the pressing plate can move in the direction far away from the machining table 300 and keeps a certain distance with the machining table, so that the nailing device can move smoothly along with the machining direction and cannot interfere with a workpiece. The reset member may be a reset spring.

In an alternative embodiment, as shown in fig. 2, the nailing device further includes a first bracket 140, and the holding member 110 and the second punch 122 are mounted on both sides of the first bracket 140 in the Z direction; the output end of the elevating member 130 is connected to the first bracket 140. By mounting both the clamping member 110 and the second stamping 122 on the first bracket 140, the assembly space is saved, and the stability of the impact effect of the second stamping 122 on the workpiece is ensured. Under the action of the lifting component 130, the clamping component 110 and the second stamping part 122 are driven to integrally lift or descend, so that the stability of lifting action is ensured, and the reliability of plugging operation is further ensured.

In yet another embodiment, as shown in fig. 2, the nailing device further comprises a second bracket 410, the lifting member 130 being mounted to the second bracket 410; a sliding fit portion 411 is provided between the first bracket 140 and the second bracket 410. Through setting up sliding fit portion 411 to the elevating movement to clamping component 110 leads, guarantees the stability that the work piece goes up and down, and then guarantees the plug effect of work piece. The sliding fitting portion 411 may specifically include a guide rail and a slider slidably coupled to the guide rail. Wherein the guide rail is mounted on the second bracket 410 and the slider is mounted on the first bracket 140.

The tool 430 attached to the spindle 420 can be replaced to mill the circuit board according to actual requirements. In addition, it should be noted that the clamping jaw 113 can clamp the workpiece and also can clamp the tool 430, the tool 430 is taken out of the tool magazine 720 through the clamping jaw 113, the spindle 420 finishes clamping the tool 430 and moves to a position above the machining table 300 to be drilled, and drilling operation on the machining table 300 is finished, so that an additional tool 430 manipulator is not required to be equipped, assembly space of the equipment is saved, and manufacturing cost of the equipment can be reduced.

In addition, the pressing foot 620 can discharge the wood chips generated during drilling.

Fig. 1 is a schematic structural diagram of a processing apparatus 10 according to an embodiment of the present invention. As shown in fig. 1, the present invention further provides a processing apparatus 10, comprising a lifting mechanism 200, a processing table 300 and the nailing device 100 as described above, wherein the nailing device 100 is connected to the lifting mechanism 200, and both are disposed above the processing table 300; the lifting mechanism 200 is used for driving the nailing device 100 to lift relative to the machining table 300. In this way, when the workpiece is pulled out, the lifting member 130 can drive the clamping member 110 to rise, and the lifting mechanism 200 can drive the entire nailing device 100 to rise, thereby driving the workpiece to rise and pulling out the workpiece from the mounting hole. Further, the nailing device 100 and the lifting mechanism 200 are provided in plural, so that the plurality of workpieces can be plugged and unplugged simultaneously by the respective nailing devices, and the plugging and unplugging efficiency is improved.

As shown in fig. 1, the processing apparatus 10 further includes a first moving mechanism 510 connected to the lifting mechanism 200, wherein the first moving mechanism 510 is configured to drive the lifting mechanism 200 to move along the X direction; the processing apparatus 10 further includes a second moving mechanism 520 connected to the processing table 300, and the second moving mechanism 520 is configured to move the processing table 300 in the Y direction. In this manner, the machining table 300 is moved in the Y direction by the nailing device moving in the X direction so that the nailing device is located at different positions above the machining table 300, thereby inserting and extracting workpieces into and from different mounting holes on the machining table 300. The lifting mechanism 200, the first moving mechanism 510, and the second moving mechanism 520 may each be linear drives.

As shown in fig. 1, the machining apparatus 10 further includes a workpiece tray 710, the workpiece tray 710 stores therein workpieces, and the nailing device is used to insert the workpieces in the workpiece tray 710 into the mounting holes of the machining table 300 or extract and convey the workpieces in the mounting holes to the workpiece tray 710. The workpiece tray 710 may be disposed at an edge of the processing table 300, and a plurality of storage spaces spaced apart from each other are provided in the workpiece tray 710, one workpiece being provided in each storage space. When the workpiece is pulled out, the workpiece needs to be pulled out row by row or column by column, and more clearance positions are ensured. Furthermore, the heads of the workpieces with different sizes are subjected to color marking, so that the workpieces are conveniently classified and managed, and the risk of mistakenly taking the workpieces during workpiece insertion is reduced.

In the machining apparatus 10, the main spindle 420 is instructed by the control software to drill a mounting hole into which a workpiece needs to be inserted on the machining table 300. Next, the workpiece tray 710 is moved in the Y direction so that the holding member 110 is positioned above the workpiece tray 710; after the clamping driving part corresponding to the size of the workpiece controls the clamping jaw 113 to be opened, the lifting part 130 acts to enable the clamping part 110 to descend; after the clamp member 110 has clamped the workpiece, the clamp drive is actuated and the jaws 113 are closed to clamp the workpiece. Next, the machining table 300 is operated so that the clamping member 110 is positioned above the corresponding mounting hole; under the action of the lifting mechanism 200 or the lifting member 130, the clamping member 110 drives the workpiece to descend to a distance of about 2mm from the surface of the processing table 300. Then, the jaws 113 are opened by a certain stroke so that the gripping force of the jaws 113 to the workpiece is reduced, but still a gripping action is performed, and the workpiece falls and overlaps the machining table 300. Next, the first punch 121 provides a downward impact force to insert the workpiece into the mounting hole to a depth of 2-3mm, for example, when the total length of the workpiece is 10mm, the length of the workpiece inserted into the mounting hole is 2-3mm, and the workpiece protrudes from the machining table by 7-8mm, so that the workpiece can stand in the mounting hole. Finally, the clamping jaw 113 is fully opened, the second stamping part 122 acts, and the workpiece is driven into the mounting hole until the workpiece is contacted with the bottom wall of the mounting hole, and the length of the workpiece inserted into the mounting hole is 6-7 mm.

Through the degree of automation that improves plug efficiency and plug operation for the plug effect is more stable, reduces the plug fault rate.

When the workpiece needs to be pulled out from the mounting hole in the processing table 300, the lifting member 130 moves the clamping member 110 down to a certain height before the clamping member 110 can clamp the workpiece; after the clamping member 110 clamps the workpiece, the lifting member 130 drives the clamping member 110 to ascend or the lifting mechanism 200 drives the nailing device to ascend as a whole, thereby pulling out the workpiece on the machining table 300 from the mounting hole.

s10: the clamping member 110 clamps the workpiece and moves to the corresponding mounting hole of the machining table 300.

Specifically, whether the first clamp driving member 111 or the second clamp driving member 112 operates is determined according to the size of the workpiece. Taking the first clamping driving member 111 as an example, after the first clamping driving member 111 controls the clamping jaws 113 to open, the lifting member 130 operates to lower the clamping member 110, and after the clamping member 110 can clamp the workpiece, the clamping driving member operates to close the clamping jaws 113 to clamp the workpiece. Next, the machining table 300 is operated so that the clamp member 110 is positioned above the corresponding mounting hole. Under the action of the lifting mechanism 200 or the lifting member 130, the clamping member 110 drives the workpiece to descend to a distance of about 2mm from the surface of the processing table 300.

S20: the clamping members 110 are opened a third predetermined distance to release the workpiece, which falls and overlaps the processing station 300.

Specifically, the third predetermined distance is smaller than the first predetermined distance, so that the clamping jaw 113 is opened by a certain stroke and still performs a clamping function on the workpiece, the clamping force of the clamping jaw 113 on the workpiece is reduced and still performs a clamping function, and the workpiece falls and overlaps with the processing table 300.

S30: a first pressure is applied to the workpiece to insert the workpiece into the mounting hole to a first predetermined depth.

Specifically, the first stamping 121 provides a downward impact force to insert the workpiece into the mounting hole to 2-3mm, for example, 10mm in height, and the workpiece protrudes out of the machining table by 7-8mm, so that the workpiece can stand in the mounting hole.

In addition, after the workpiece is inserted into the mounting hole to the first predetermined depth, the clamping member 110 may be configured to open for the first predetermined distance or the second predetermined distance, so that the clamping jaw 113 is fully opened, and thus the clamping jaw 113 no longer provides a clamping force to the workpiece.

S40: and applying a second pressure to the workpiece to insert the workpiece into the mounting hole to a second predetermined depth. The workpiece is driven into the mounting hole completely by the second punch 122, i.e., the workpiece contacts the bottom wall of the mounting hole and protrudes to a certain extent relative to the surface of the machining table 300.

The method for inserting a workpiece according to the present invention takes the first clamping driving member 111 as an example. First, after the first clamping driving member 111 controls the clamping jaw 113 to open for a first preset distance, the lifting member 130 is operated to lower the clamping member 110, and after the clamping member 110 clamps the workpiece, the first clamping driving member 111 is operated, and the clamping jaw 113 is closed to clamp the workpiece. Next, the clamping member 110 drives the workpiece to descend to a distance of about 2mm from the surface of the processing table 300 by the lifting mechanism 200 or the lifting member 130. Next, the clamping member 110 is opened by a third predetermined distance, so that the jaws 113 are opened by a certain stroke and still clamp the workpiece, the clamping force of the jaws 113 on the workpiece is reduced and still clamp the workpiece, and the workpiece falls and overlaps the machining table 300. The first punch 121 then provides a downward impact force to insert the workpiece into the mounting hole to 2-3mm where the workpiece can stand. Further, the gripping members 110 are opened a first predetermined distance such that the jaws 113 are fully opened such that the jaws 113 no longer provide a clamping force on the workpiece. Finally, the second punch 122 is actuated to drive the workpiece completely into the mounting hole so that the workpiece is inserted into the machining station 300.

In the action process of the first stamping part 121, the clamping part 110 always provides clamping force for the workpiece, so that the clamping part 110 can provide supporting force for two radial sides of the workpiece, the workpiece is prevented from being inclined, and the workpiece is ensured to be vertically inserted into the mounting hole. Meanwhile, in the process of the action of the second stamping part 122, the clamping part 110 is opened relative to the workpiece, so that the interference on the driving operation of the workpiece is avoided, and the workpiece is ensured to be completely driven into the mounting hole. Moreover, because the workpiece is vertically inserted into the mounting hole, the operation difficulty of subsequently pulling the workpiece can be reduced, and the efficiency of pulling and inserting the workpiece is ensured. That is to say, through the degree of automation that improves plug efficiency and plug operation, can make the plug effect more stable, reduce the plug fault rate.
