Description

The positioning plate is used to place the PCB, and both the positioning element and the clamping element are connected to the positioning plate. The clamping element can move closer to or away from the positioning element. When the clamping element approaches the positioning element, it can push the PCB located between the two closer to the positioning element, and eventually make the PCB abut against the positioning element, thereby achieving coarse positioning of the PCB.

This chip suction device has a chip suction hood, and during drilling, the pressure foot of the hood presses against the PCB. Additionally, the pressure foot surrounds the outside of the drill bit.

[0005] However, in real-world scenarios, the presser foot presses against the positioning and clamping components, causing the presser foot to tilt at a large angle, making the drill bit prone to colliding with the presser foot and thus damaging the drill bit. Utility Model Content

[0034] In order to make the technical problems, technical solutions and beneficial effects solved by the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0035] In the description of the present application, it should be pointed out that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting" and "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0036] As shown in Figure 1 and Figure 2 In an embodiment, the positioning device 10 comprises a positioning plate 1, a positioning member 2 and a clamping member 3; the positioning member 2 and the clamping member 3 are arranged at intervals on the positioning plate 1; the clamping member 3 is slidingly connected to the positioning plate 1, and the clamping member 3 is used to push the material close to the positioning member 2; at least one of the positioning member 2 and the clamping member 3 can move in the vertical direction to adjust the height relative to the positioning plate 1.

[0037] The arrangement direction of the positioning member 2 and the clamping member 3 is perpendicular to the vertical direction. Figure 1 and Figure 2 In the example shown, the vertical direction is parallel to the Z axis, and the arrangement direction of the positioning member 2 and the clamping member 3 is parallel to the X axis and / or the Y axis. In actual scenarios, the vertical direction can be the up-down direction, and the arrangement direction of the positioning member 2 and the clamping member 3 can be the horizontal direction.

[0038] In this embodiment, when the clamping member 3 is driven to move close to the positioning member 2 along the arrangement direction of the positioning member 2 and the clamping member 3, the material 20 located between the clamping member 3 and the positioning member 2 can be pushed to move close to the positioning member 2, and finally the material 20 can be brought into contact with the positioning member 2, so that the material 20 can be positioned.

[0039] Since at least one of the positioning member 2 and the clamping member 3 can move in the vertical direction to adjust the height thereof relative to the positioning plate, in the subsequent drilling process of the material 20, the height of the at least one of the positioning member 2 and the clamping member 3 that can move in the vertical direction can be adjusted to be equivalent to the height of the positioning plate, so that when the pressure foot 30 of the dust cover is pressed thereon, the inclination angle of the pressure foot 30 can be reduced, and the collision of the drill with the pressure foot 30 can be effectively avoided.

[0040] As shown in Figure 2 In an embodiment, in the vertical direction, the positioning plate 1 has a bearing surface 11 and a bottom surface 12 arranged opposite to each other, and the material 20 placed on the positioning plate 1 is actually placed on the bearing surface 11. In actual scenarios, the bearing surface 11 is the upper surface of the positioning plate 1, and the bottom surface 12 is the lower surface of the positioning plate 1.

[0041] In addition, after assembly, the positioning member 2 and the clamping member 3 both protrude from the bearing surface 11 in the direction from the bottom surface 12 to the bearing surface 11, so that the material placed on the positioning plate 1 can be clamped by the positioning member 2 and the clamping member 3, and the material placed on the positioning plate 1 can be positioned.

[0042] In addition, when drilling the material 20 on the positioning plate 1, the pressure foot 30 presses the material 20 in the direction from the bearing surface 11 to the bottom surface 12 (i.e., from top to bottom). When the pressure foot 30 is pressed on the positioning member 2, it is pressed on the positioning member 2 in the direction from the bearing surface 11 to the bottom surface 12; when the pressure foot 30 is pressed on the clamping member 3, it is pressed on the clamping member 3 in the direction from the bearing surface 11 to the bottom surface 12.

[0043] As shown in Figure 2As shown, in an embodiment, the positioning plate 1 is provided with a mounting hole 13, and the positioning member 2 comprises an elastic member 21 and a pin 22; the elastic member 21 is arranged in the mounting hole 13; one end of the pin 22 is located in the mounting hole 13; the elastic member 21 is located between the positioning plate 1 and the pin 22 and can be elastically deformed and reset in the vertical direction to change the length of the pin 22 extending out of the mounting hole 13, thereby realizing the movement of the positioning member 2 in the vertical direction.

[0044] In this case, the mounting hole 13 can be arranged on the bearing surface 11 and form a first opening on the bearing surface 11, and in this case, the pin 22 extending out of the mounting hole 13 means that the pin 22 extends out of the mounting hole 13 from the first opening.

[0045] In the initial state, the other end of the pin 22 is located outside the mounting hole 13, and when the clamping member 3 pushes the material 20 against the positioning member 2, the material 20 is actually against the pin 22.

[0046] When the presser foot 30 presses the pin 22 in the direction from the bearing surface 11 to the bottom surface 12, the pin 22 will move into the mounting hole 13. In this case, under the action of the pressing force, the pin 22 can be completely inserted into the mounting hole 13; or under the action of the pressing force, the pin 22 can only be partially retracted into the mounting hole 13.

[0047] In this case, the elastic member 21 can be a spiral spring or the like.

[0048] In addition, the pin 22 is limited by the hole wall of the mounting hole 13 to avoid movement in the radial direction of the mounting hole 13. In this case, the diameter of the mounting hole 13 matches the diameter of the pin 22, and the two can be clearance fit, and the tolerance of the fit can be set according to actual needs.

[0049] In an embodiment, the positioning plate 1 is provided with a first limiting structure, and the pin 22 is provided with a second limiting structure, and when the pin 22 moves in the direction from the bottom surface 12 to the bearing surface 11, the first limiting structure can abut against the second limiting structure to limit the pin 22 in the mounting hole 13, thereby avoiding the pin 22 from falling off the positioning plate 1.

[0050] In this case, the first limiting structure can be a press ring, which is embedded in the mounting hole 13 and is sleeved on the outside of the pin 22, and the press ring and the mounting hole 13 can be interference fit, and the press ring and the pin 22 can be clearance fit. The second limiting structure can be a protruding structure arranged on the side surface of the pin 22, and the protruding structure is located between the press ring and the bottom surface 12 of the mounting hole 13.

[0051] In the initial state, the protruding structure is spaced apart from the bottom surface 12 of the mounting hole 13. In addition, the protruding structure can also be an annular structure which is arranged around the pin 22 along the axis of the pin 22, and the outer diameter of the protruding structure is greater than the inner diameter of the compression ring, and the outer diameter of the protruding structure is less than the diameter of the mounting hole 13.

[0052] In addition, in this embodiment, one end of the elastic member 21 can be abutted against the bottom surface 12 of the mounting hole 13, and the other end of the elastic member 21 can be abutted against the protruding structure.

[0053] It should be noted that the mounting hole 13 can also be a through hole, and the positioning plate 1 further has other structures capable of abutting against the elastic member 21 to prevent the elastic member 21 from falling off from the opening formed by the mounting hole 13 on the bottom surface 12, for example, the inner surface of the mounting hole 13 is provided with an abutting structure, and one end of the elastic member 21 is abutted against the abutting structure, and the other end of the elastic member 21 can be abutted against the protruding structure (or other positions of the pin 22).

[0054] As shown in FIG. 1, Figure 2 In an embodiment, the positioning device 10 further includes a clamping driving module 4, the clamping member 3 is connected to the positioning plate 1 through the clamping driving module 4, and the clamping driving module 4 is used to drive the clamping member 3 to reciprocate in the arrangement direction of the positioning member 2 and the clamping member 3, so that the material is close to the positioning member 2.

[0055] In an embodiment, the clamping driving module 4 can be a pneumatic cylinder, wherein the cylinder body of the pneumatic cylinder is connected to the positioning plate 1, and the piston rod of the pneumatic cylinder is connected to the clamping member 3. In other embodiments, the clamping driving module 4 can also be a rotary motor and a gear rack mechanism, wherein the housing of the rotary motor can be connected to the positioning plate 1, the main shaft of the rotary motor is connected to the gear of the gear rack mechanism, the rack of the gear rack mechanism is connected to the clamping member 3, and the rack extends along the arrangement direction of the positioning member 2 and the clamping member 3. When the main shaft of the rotary motor rotates, the clamping member 3 can be driven to move linearly along the arrangement direction of the positioning member 2 and the clamping member 3. Of course, the gear rack mechanism can also be replaced by a screw transmission mechanism, a chain transmission mechanism or a belt transmission mechanism, etc.

[0056] As shown in FIG. 1, Figure 1 In an embodiment, the bearing surface 11 is provided with an avoiding groove 14 which extends along the arrangement direction of the positioning member 2 and the clamping member 3, and the avoiding groove 14 penetrates through the positioning plate 1; the clamping member 3 is arranged in the avoiding groove 14 and can move in the avoiding groove 14 along the arrangement direction of the positioning member 2 and the clamping member 3.

[0057] In one embodiment, the clamping drive module 4 is connected to the bottom surface 12; this can effectively prevent the clamping drive module 4 from interfering with the material 20 placed on the bearing surface 11, and can also effectively prevent the clamping drive module 4 from colliding with external objects.

[0058] One end of the clamping member 3 may extend out of the clearance groove 14 along the direction from the bearing surface 11 to the bottom surface 12 to connect to the clamping drive module 4; the other end of the clamping member 3 may extend out of the clearance groove 14 along the direction from the bottom surface 12 to the bearing surface 11 to push the material 20.

[0059] In addition, in the arrangement direction of the positioning member 2 and the clamping member 3, the clearance groove 14 can also penetrate the positioning plate 1 along the direction from the positioning member 2 to the clamping member 3.

[0060] like Figure 2 As shown, in one embodiment, the positioning device 10 further includes a clamping drive module 5; the clamping member 3 is connected to the clamping drive module 4 via the clamping drive module 5, or the clamping drive module 4 is connected to the positioning plate 1 via the clamping drive module 5; the clamping drive module 5 is used to drive the clamping member 3 to reciprocate in the vertical direction, so that the clamping member 3 can press the material 20 on the positioning plate 1. This is more conducive to keeping the material 20 in the corresponding position on the positioning plate 1 and improving the positioning effect of the material 20. Moreover, the driving action of the clamping drive module 5 can realize the movement of the clamping member 3 in the vertical direction to adjust the height of the clamping member 3 relative to the positioning plate 1. During the drilling process of the material 20 on the positioning plate 1, the clamping member 3 can be driven by the clamping drive module 5 to move along the direction from the bearing surface 11 to the bottom surface 12, thereby reducing its height relative to the positioning plate 1. In this way, when the press foot 30 presses on it, the tilt angle of the press foot 30 can be reduced, effectively avoiding the drill bit from colliding with the press foot 30.

[0061] When the clamping member 3 is connected to the clamping drive module 4 through the pressing drive module 5, the clamping drive module 4 can drive the clamping member 3 and the pressing drive module 5 to move synchronously along the arrangement direction of the positioning member 2 and the clamping member 3.

[0062] When the clamping drive module 4 is connected to the positioning plate 1 through the pressing drive module 5, the pressing drive module 5 can drive the clamping member 3 and the clamping drive module 4 to move synchronously in the vertical direction.

[0063] In addition, the structure of the clamping drive module 5 can be the same as that of the clamping drive module 4, which will not be described in detail in this embodiment.

[0064] like Figure 3As shown, in an embodiment, the clamping member 3 comprises a connecting column 31 and a pressing plate 32; the connecting column 31 is connected with the pressing driving module 5 and the pressing plate 32 respectively; the pressing plate 32 has a pressing portion 321 protruding from a side of the connecting column 31 close to the positioning member 2 in the arrangement direction of the positioning member 2 and the clamping member 3; when the clamping driving module 4 drives the connecting column 31 to be close to the positioning member 2, the connecting column 31 can push the material 20 to be close to the positioning member 2; when the pressing driving module 5 drives the pressing portion 321 to be close to the positioning plate 1 in the vertical direction, the pressing portion 321 can press the material 20 on the bearing surface 11.

[0065] In use, the clamping member 3 is first driven to be close to the positioning member 2 in the arrangement direction of the positioning member 2 and the clamping member 3, so as to push the material 20 to be close to the positioning member 2 by the connecting column 31; subsequently, the clamping member 3 can be directly driven to make the pressing portion 321 close to the positioning plate 1 in the vertical direction, so that the pressing plate 32 can press the material 20 on the positioning plate 1, thereby improving the production efficiency.

[0066] It should be understood that after assembly, the connecting column 31 protrudes from the bearing surface 11 in the direction from the bottom surface 12 to the bearing surface 11. Moreover, in the vertical direction, the bearing surface 11 is located between the bottom surface 12 and the pressing portion 321, and the pressing portion 321 close to the positioning plate 1 actually means that it moves in the direction from the bearing surface 11 to the bottom surface 12.

[0067] In an embodiment, the connecting column 31 can be a cylindrical structure, and of course, in other embodiments, the connecting column 31 can also be a prism such as a cuboid.

[0068] As shown in the example, Figure 3 in an embodiment, the pressing portion 321 is of a ring structure and is arranged around the connecting column 31. In this way, the pressing portion 321 can have greater strength, and in actual production, through the arrangement of this embodiment, the thickness of the pressing portion 321 can be reduced while the strength of the pressing portion 321 meets the needs. In the subsequent drilling process of the material 20, when the pressing foot 30 is pressed to the clamping member 3 (mainly on the pressing portion 321) in the direction from the bearing surface 11 to the bottom surface 12, the inclination angle of the pressing foot 30 can be reduced, effectively avoiding the collision of the drill with the pressing foot 30.

[0069] Here, the thickness of the pressing portion 321 can refer to the size of the pressing portion 321 in the vertical direction.

[0070] In Figure 3 the example shown, the pressing portion 321 is of a circular ring structure, wherein the pressing portion 321 and the connecting column 31 can be coaxially arranged.

[0071] As shown in the example, Figure 3As shown, in one embodiment, the pressure plate 32 further includes a connecting portion 322, which is connected to the connecting post 31, and a pressing portion 321 is connected to the connecting portion 322. In the vertical direction, the thickness of the connecting portion 322 is greater than the thickness of the pressing portion 321. Along the vertical direction, the connecting portion 322 protrudes from the side of the pressing portion 321 away from the positioning plate 1, that is, along the direction from the bottom surface 12 to the bearing surface 11, the connecting portion 322 protrudes from the pressing portion 321.

[0072] The strength of the pressing part 321 can be further improved by the connection part 322, so that the thickness of the pressing part 321 can be made thinner.

[0073] In one embodiment, the connecting part 322 may be a frustum structure, with the cross-sectional radius of the frustum gradually decreasing along the direction from the bottom surface 12 to the bearing surface 11.

[0074] like Figure 1 As shown, in one embodiment, there are two positioning members 2, namely a first positioning member 2a and a second positioning member 2b; there are two clamping members 3, namely a first clamping member 3a and a second clamping member 3b; the first positioning member 2a and the first clamping member 3a are spaced apart along a first direction, and the first clamping member 3a is used to push the material closer to the first positioning member 2a along the first direction; the second positioning member 2b and the second clamping member 3b are spaced apart along a second direction, and the second clamping member 3b is used to push the material closer to the second positioning member 2b along the second direction; the first direction, the second direction, and the vertical direction are perpendicular to each other. Figure 1 In the example shown, the first direction is parallel to the X-axis, and the second direction is parallel to the Y-axis.

[0075] With the settings of this embodiment, material positioning can be achieved in both the first and second directions, improving the positioning effect of the material.

[0076] In this embodiment, the "arrangement direction of positioning member 2 and clamping member 3" includes: the arrangement direction of the first positioning member 2a and the first clamping member 3a, and the arrangement direction of the second positioning member 2b and the second clamping member 3b. For the first positioning member 2a and the first clamping member 3a, the "arrangement direction of positioning member 2 and clamping member 3" is the first direction; for the second positioning member 2b and the second clamping member 3b, the "arrangement direction of positioning member 2 and clamping member 3" is the second direction.

[0077] In one embodiment, two clamping drive modules 4 are provided, one of which corresponds to one clamping member 3. The clamping drive module 4 is used to drive the corresponding clamping member 3 to move along the arrangement direction of the positioning member 2 and the clamping member 3.

[0078] Similarly, there are two clamping drive modules 5, one of which corresponds to one clamping member 3. The clamping drive module 5 is used to drive the corresponding clamping member 3 to move in the vertical direction.

[0079] In one embodiment, a clearance groove 14 corresponds to a clamping member 3. The clamping member 3 passes through the clearance groove 14 corresponding to it and can move within the clearance groove 14 along the arrangement direction of the positioning member 2 and the clamping member 3.

[0080] In practical scenarios, the positioning component 2 and clamping component 3 are mainly used to perform coarse positioning of the material on the positioning plate 1. Before drilling the material, the material that has been coarsely positioned will also be precisely positioned.

[0081] like Figure 1 As shown, in the first embodiment, the positioning device 10 further includes a first PIN module 6, which is used for precise positioning of the material 20. The first PIN module 6 includes a first PIN driving assembly and a first PIN pin. The first PIN driving assembly connects the positioning plate 1 and the first PIN pin, and is used to drive the first PIN pin to reciprocate along the vertical direction. When the first PIN pin moves along the direction from the bottom surface 12 to the bearing surface 11, it can be inserted into the first positioning hole of the material 20 that is being coarsely positioned, thereby achieving precise positioning of the material 20 in the first direction.

[0082] The first set of PIN driving components can be connected to the bottom surface 12. When the first PIN moves along the direction from the bearing surface 11 to the bottom surface 12, it can move to the bottom of the bearing surface 11 or move to the top of the first PIN and be flush with the bearing surface 11.

[0083] Furthermore, when the first PIN is inserted into the first positioning hole, the material 20 can be pushed to move a certain distance along the direction from the positioning member 2 to the clamping member 3 in the arrangement direction of the positioning member and the clamping member, so that the material 20 is disengaged from the positioning member 2. Specifically, when the first PIN is inserted into the first positioning hole, the material 20 can be pushed to move a certain distance along the direction from the first positioning member to the first clamping member 3a in the first direction. During the process of driving the first PIN to insert into the first positioning hole, the clamping member 3 does not press the material 20, and the clamping drive module 4 does not provide a force towards the positioning member 2 to the clamping member 3.

[0084] In one embodiment, the bearing surface 11 is provided with a first clearance hole, which extends vertically to the bottom surface 12, and the first PIN pin is inserted into the first clearance hole.

[0085] Figure 1As shown, in the second embodiment, the positioning device 10 further comprises a second set of PIN modules 7, which are used for fine positioning of the material 20. The second set of PIN modules 7 comprises a second set of PIN driving assemblies and second PIN needles, the second set of PIN driving assemblies are connected to the positioning plate 1 and the second PIN needles, and are used for driving the second PIN needles to reciprocate along the vertical direction. When the second PIN needles move along the direction from the bottom surface 12 to the bearing surface 11, they can be inserted into the second positioning holes of the coarsely positioned material 20, thereby achieving fine positioning of the material 20 in the second direction.

[0086] The second set of PIN driving assemblies can be connected to the bottom surface 12, and when the second PIN needles move along the direction from the bearing surface 11 to the bottom surface 12, they can be moved below the bearing surface 11 or the top ends of the second PIN needles are flush with the bearing surface 11.

[0087] In addition, when the second PIN needles are inserted into the second positioning holes, the material 20 can be pushed to move a certain distance in the second direction from the second positioning member to the second clamping member 3b, so as to make the material 20 out of contact with the second positioning member. In the process of driving the second PIN needles to be inserted into the second positioning holes, the second clamping member 3b does not press the material 20, and the second clamping driving assembly can not provide a force to the second clamping member 3b towards the second positioning member.

[0088] In an embodiment, the bearing surface 11 is provided with a second avoiding hole, which penetrates to the bottom surface 12 along the vertical direction, and the second PIN needles are arranged in the second avoiding hole.

[0089] The embodiment of the utility model further provides a processing equipment, the structural equipment includes processing device and the positioning device 10 described in any one of the above embodiments, wherein the processing device can process the material 20 positioned by the positioning device 10.
