[0050] Reference Figure 1 As shown, Figure 1 This is a schematic axial view of the positioning device provided in an embodiment of this application. This embodiment discloses a positioning device including a pneumatic clamp positioning mechanism 1 and a locking mechanism 2. The pneumatic clamp positioning mechanism 1 is used to position a board (which can be a circuit board), and includes a support base 11 and a clamping assembly 12, with the clamping assembly 12 disposed on the support base 11. The locking mechanism 2 is connected to the clamping assembly 12 and is used to lock or release the clamping assembly 12.

[0051] Specifically, the support base 11 has a first end 110 and a second end 111. The clamping assembly 12 includes a first clamping assembly and a second clamping assembly. The first clamping assembly includes a first clamping member 120 and a second clamping member 121. The second clamping assembly includes a third clamping member 122 and a fourth clamping member 123. The first clamping member 120 and the second clamping member 121 are respectively disposed at the first end 110 to form a first clamping portion 124. The third clamping member 122 and the fourth clamping member 123 are respectively disposed at the second end 111 to form a second clamping portion 125. The first clamping portion 124 and the second clamping portion 125 are used to position the plate. The locking mechanism 2 is connected to the first clamping member 120 and is used to lock or release the first clamping member 120.

[0052] In this embodiment, the first clamping member 120 is movably disposed at the first end 110, and the locking mechanism 2 is connected to the first clamping member 120 for locking or releasing the first clamping member 120. It is understood that in other embodiments, the second clamping member 121 may also be movably disposed at the first end 110, and the locking mechanism 2 may be connected to the second clamping member 121 for locking or releasing the second clamping member 121. Alternatively, the first clamping member 120 and the second clamping member 121 may be movably disposed at the first end 110 respectively, and the locking mechanism 2 may be connected to both the first clamping member 120 and the second clamping member 121 for locking or releasing both. In this embodiment, the stability of the clamped plate is ensured by providing two sets of clamping components, the first clamping component and the second clamping component. It is understood that in other embodiments, three or more sets of clamping components may also be provided.

[0053] This embodiment includes a pneumatic clamp positioning mechanism 1 and a locking mechanism 2. The pneumatic clamp positioning mechanism 1 includes a clamping component 12, and the locking mechanism 2 is connected to the clamping component 12. When the pneumatic clamp positioning mechanism 1 positions the plate, the locking mechanism 2 locks the clamping component 12, which increases the secondary locking direction, prevents the clamping component 12 from shifting, improves the stability of the clamping component 12, thereby improving the positioning accuracy of the pneumatic clamp positioning mechanism 1 and ensuring the processing quality of the plate.

[0054] Continue to refer to Figure 1 As shown, the pneumatic clamp positioning mechanism 1 also includes a first positioning element 13 and a second positioning element 17. A first clamping part 124 is used to clamp the first positioning element 13, and a second clamping part 125 is used to clamp the second positioning element 17. The first positioning element 13 is provided with a first positioning hole, and the second positioning element 17 is provided with a second positioning hole. The first positioning hole and the second positioning hole are used to engage with the pins of the sheet metal for positioning. In this embodiment, by providing the first positioning element 13 and the second positioning element 17, drilling positioning holes in the new first positioning element 13 and the second positioning element 17 each time the sheet metal is processed can ensure the relative positional accuracy of the first positioning element 13 and the second positioning element 17 with the processing drill bit, thereby ensuring the positioning accuracy of the sheet metal, improving the processing quality of the sheet metal, and avoiding the problem of needing to recalibrate the position after a period of use of conventional pneumatic clamps.

[0055] In this embodiment, multiple first positioning members 13 and second positioning members 17 are provided, each with a different diameter for the first positioning hole and a different diameter for the second positioning hole, to accommodate pins of different sizes on the plate. The first clamping part 124 is an elongated clamping groove, and the first positioning member 13 can be placed at any position within the first clamping part 124, thereby adjusting the distance between the first positioning member 13 and the second positioning member 17. Specifically, the position of the first positioning member 13 can be set according to the distance between the pins on the plate, improving the applicability of the positioning device.

[0056] In this embodiment, the first positioning element 13 and the second positioning element 17 are respectively made of polyoxymethylene (POM). POM is easy to process and has good wear resistance, which facilitates drilling of the first positioning element 13 and the second positioning element 17, reduces processing difficulty, and improves processing efficiency. It is understood that in other embodiments, the first positioning element 13 and the second positioning element 17 may also be made of other materials, such as glass fiber.

[0057] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, Figure 2 This is a schematic diagram showing the connection between the locking mechanism and the first clamping member of the positioning device provided in the embodiments of this application. Figure 3This is a schematic structural diagram of the locking mechanism of the positioning device provided in the embodiments of this application. Figure 4 This is a bottom view of the locking mechanism of the positioning device provided in an embodiment of this application. Figure 5 This is a schematic diagram showing the connection between the pressing member and the first clamping member of the positioning device provided in this application embodiment. The locking mechanism 2 includes a first driving member 21 and a pressing assembly 22. The pressing assembly 22 is provided in two sets, and the two sets of pressing assemblies 22 are respectively connected to both ends of the first driving member 21, and the two sets of pressing assemblies 22 are respectively connected to both ends of the first clamping member 120 to enhance the stability when locking the first clamping member 120.

[0058] Specifically, each pressing assembly 22 includes a first movable member 220, a fixed part 221, a connecting shaft 222, a second movable member 223, and a pressing member 224. The connecting shaft 222 passes through the fixed part 221. One end of the first movable member 220 is rotatably connected to the first driving member 21, and the other end of the first movable member 220 is rotatably connected to the connecting shaft 222. One end of the second movable member 223 is rotatably connected to the connecting shaft 222, and the other end of the second movable member 223 is connected to the pressing member 224. The first clamping member 120 is provided with a locking hole 120a, and the pressing member 224 passes through the locking hole 120a. The locking hole 120a is provided with a first limiting part 120b, and the pressing member 224 is provided with a first limiting mating part 224a. The first limiting part 120b and the first limiting mating part 224a are mated together.

[0059] After the first clamping member 120 and the second clamping member 121 cooperate to clamp the first positioning member 13, the first driving member 21 drives the first movable member 220 to move in a direction close to the first driving member 21, so as to drive the second movable member 223 to move in a direction close to the first driving member 21. The movement of the second movable member 223 drives the pressing member 224 to move in the locking hole 120a, so as to cooperate with the first limiting part 120b and the first limiting mating part 224a, so that the pressing member 224 abuts against the first clamping member 120 to lock the first clamping member 120.

[0060] In this embodiment, the first limiting part 120b is a first inclined surface, and the first limiting mating part 224a is a second inclined surface. After the first clamping member 120 and the second clamping member 121 cooperate to clamp the first positioning member 13, the first inclined surface and the second inclined surface abut against each other to lock the first clamping member 120 in a direction perpendicular to the first inclined surface. Compared with conventional pneumatic clamps, higher precision positioning and clamping is achieved. It can be understood that in other embodiments, the first limiting part 120b and the first limiting mating part 224a can also be other structures. For example, the first limiting part 120b can be a first step, and the first limiting mating part 224a can be a second step, with the first step and the second step corresponding to each other. Alternatively, the first limiting part 120b can also be a groove, and the first limiting mating part 224a can also be a protrusion, with the groove and the protrusion corresponding to each other.

[0061] Reference Figure 6 , Figure 7 and Figure 8 As shown, Figure 6 This is a schematic diagram showing the connection between the first clamping member and the first movable component of the positioning device provided in this application embodiment. Figure 7 This is a schematic diagram of the structure of the first movable component of the positioning device provided in an embodiment of this application. Figure 8 This is a schematic diagram of the structure of the second movable component of the positioning device provided in an embodiment of this application. The pneumatic clamp positioning mechanism 1 further includes a second driving member 14, a third driving member 18, a first movable component 15, and a second movable component 16. The second driving member 14 is connected to the first clamping member 120 through the first movable component 15 and is used to drive the first clamping member 120 to move, so that the first clamping member 120 cooperates with the second clamping member 121 to clamp or release the first positioning member 13. The third driving member 18 is connected to the third clamping member 122 through the second movable component 16 and is used to drive the third clamping member 122 to move, so that the third clamping member 122 cooperates with the fourth clamping member 123 to clamp or release the second positioning member 17.

[0062] In this embodiment, the second driving member 14 is connected to the first clamping member 120 and is used to drive the first clamping member 120 to move. The third driving member 18 is connected to the third clamping member 122 and is used to drive the third clamping member 122 to move. This embodiment ensures the stability of clamping by driving only one clamping member to move. It can be understood that in other embodiments, the second driving member 14 can also be connected to the first clamping member 120 and the second clamping member 121 at the same time to drive the first clamping member 120 and the second clamping member 121 to move relative to each other. The third driving member 18 can be connected to the third clamping member 122 and the fourth clamping member 123 at the same time to drive the third clamping member 122 and the fourth clamping member 123 to move relative to each other. The locking mechanism 2 is connected to the movable clamping member.

[0063] Specifically, the first movable component 15 includes a first connecting rod 150, a first connecting member 151, a second connecting member 152, a first rotating shaft 153, and a second rotating shaft 154, with the first rotating shaft 153 and the second rotating shaft 154 respectively disposed at the first end 110. The first connecting member 151 is movably connected to the first rotating shaft 153. The second connecting member 152 is movably connected to the second rotating shaft 154. The two ends of the first connecting rod 150 are respectively connected to the first connecting member 151 and the second connecting member 152. The first clamping member 120 is respectively connected to the first connecting member 151 and the second connecting member 152. The second driving member 14 is connected to the first connecting member 151. The second driving member 14 is used to drive the first connecting member 151 to rotate around the first rotating shaft 153, so as to drive the first connecting rod 150 to move. The first connecting rod 150 moves to drive the second connecting member 152 to rotate around the second rotating shaft 154, thereby driving the first clamping member 120 to move, so that the first clamping member 120 and the second clamping member 121 cooperate to clamp or release the first positioning member 13.

[0064] The second movable component 16 includes a second connecting rod 160, a third rotating shaft 161, and a guide member 162, with the third rotating shaft 161 and guide member 162 respectively disposed at the second end 111. One end of the second connecting rod 160 is connected to the third driving member 18, and the other end of the second connecting rod 160 is rotatably connected to the third rotating shaft 161. One end of the third clamping member 122 is connected to the second connecting rod 160, and the other end of the third clamping member 122 passes through the guide member 162. The guide member 162 is used to limit the third clamping member 122 to prevent it from shifting, thereby ensuring the stability of the third clamping member 122 and the fourth clamping member 123 when clamping the second positioning member 17. The third driving member 18 is used to drive the second connecting rod 160 to move, thereby moving the third clamping member 122 so that the third clamping member 122 and the fourth clamping member 123 can cooperate to clamp or release the second positioning member 17.

[0065] In this embodiment, the first clamping member 120 has a serrated structure on the side facing the second clamping member 121, and the second clamping member 121 has a serrated structure on the side facing the first clamping member 120. This improves the anti-slip performance when the first clamping member 120 and the second clamping member 121 clamp the first positioning member 13, thereby ensuring the stability of the first clamping member 120 and the second clamping member 121 when clamping the first positioning member 13.

[0066] In this embodiment, the fourth clamping member 123 has a groove at one end facing the third clamping member 122, and the opening of the groove gradually decreases from the end near the third clamping member 122 toward the end away from the third clamping member 122. Understandably, the groove is designed as a V-shaped groove, and the opening at the end of the groove near the third clamping member 122 is larger, thereby enabling the second positioning members 17 of different sizes to be pressed tightly in the groove, improving the applicability and versatility of the third clamping member 122 and the fourth clamping member 123. Furthermore, the displacement of the second positioning member 17 in the planar direction is restricted by the V-shaped groove and the third clamping member 122, improving the stability when the third clamping member 122 and the fourth clamping member 123 clamp the second positioning member 17. Moreover, the inner wall of the V-shaped groove is designed as a serrated structure, improving the anti-slip performance when the third clamping member 122 and the fourth clamping member 123 clamp the second positioning member 17, thereby further improving the stability when clamping the second positioning member 17. It is understood that in other embodiments, the end of the third clamping member 122 facing the fourth clamping member 123 may also be provided with a V-shaped groove.

Figure 11 This is a schematic diagram of the limiting mechanism of the positioning device provided in the embodiment of this application. The positioning device also includes a limiting mechanism 3, which includes a driving component 31, a first limiting member 32, and a second limiting member 33. The driving component 31 is provided in two sets, which are respectively disposed at the end of the first end 110 and the end of the second end 111. The support base 11 is also provided with a first receiving groove 112 and a second receiving groove 113 for accommodating the first limiting member 32 and the second limiting member 33, respectively. The first receiving groove 112 is correspondingly disposed with the first limiting member 32, and the second receiving groove 113 is correspondingly disposed with the second limiting member 33.

[0068] Specifically, each drive assembly 31 includes a fourth drive member 310, a fixed base 311, a first gripper 312, a second gripper 313, a first slide rail 314, a second slide rail 315, a first slider 316, a second slider 317, and a guide plate 318.

The two ends of a first limiting member 32 are respectively connected to the first slider 316 at the first end 110 and the second slider 317 at the second end 111. The two ends of a second limiting member 33 are respectively connected to the second slider 317 at the first end 110 and the first slider 316 at the second end 111. The first slider 316 has a first protrusion 316a that slidably inserts into a guide groove 318a, and the second slider 317 has a second protrusion 317a that slidably inserts into another guide groove 318a.

[0069] In this embodiment, two guide grooves 318a are symmetrically arranged about the center line of the guide plate 318. Each guide groove 318a includes a first hole and a second hole connecting to the first hole. The included angle between the first hole and the second hole is a preset included angle α, where 90°≤α≤180°, i.e., the preset included angle α is an obtuse angle or a right angle.

[0093] This embodiment also provides a workbench for processing PCB boards. The workbench includes the positioning device of the above embodiments and the positioning method of the above embodiments for positioning the board.

[0094] This embodiment also discloses a PCB board processing equipment, which includes a bed, a frame mounted on the bed, a processing spindle movably mounted on the frame, and a worktable as described above movably mounted on the bed. The worktable is used to position and clamp the PCB board, and the processing spindle is used to process the PCB board on the worktable.

[0095] In specific application scenarios, when positioning the board material, the distance between the pins on the board material is first measured. Then, the first positioning member 13 and the second positioning member 17 are placed into the first clamping part 124 and the second clamping part 125 respectively by the robot arm, so that the distance between the two positioning members is the same as the distance between the pins on the board material. Then, the first clamping member 120 is driven to move by the second driving member 14, so that the first clamping member 120 and the second clamping member 121 cooperate to clamp the first positioning member 13. The third clamping member 122 is driven to move by the third driving member 18, so that the third clamping member 122 and the fourth clamping member 123 cooperate to clamp the second positioning member 17. Then, the pressing member 224 is pressed against the first clamping member 120 by the first driving member 21 to lock the first clamping member 120. Finally, the positioning holes of the first positioning member 13 and the second positioning member 17 are drilled by the spindle.

[0096] When the automatic feeding mechanism is activated, the fourth drive unit 310 drives the first gripper 312 and the second gripper 313 to move in opposite directions. At this time, the first slider 316 and the second slider 317 slide, and the first protrusion 316a and the second protrusion 317a move from the second position C to the first position B, so that the first limiting member 32 leaves the first receiving groove 112 and the second limiting member 33 leaves the second receiving groove 113. After moving into position, a limiting groove 34 is formed between the first limiting member 32 and the second limiting member 33. The position of the pin on the plate is restricted by the limiting groove 34. Then, the fourth drive unit 310 drives the first gripper 312 and the second gripper 313 to move in opposite directions, so that the first limiting member 32 and the second limiting member 33 move in opposite directions, so that the first limiting member 316a moves in opposite directions. 32 returns to the first receiving groove 112, and the second limiting member 33 returns to the second receiving groove 113. Then, the pin on the plate falls into the positioning holes of the first positioning member 13 and the second positioning member 17. Then, the positioning is completed by pressing down through the pressure plate mechanism. After the plate is processed, the fourth driving member 310 drives the first gripper 312 and the second gripper 313 to move in opposite directions, so that the upper surfaces of the first limiting member 32 and the second limiting member 33 are higher than the upper surface of the bearing seat 11. At this time, the plate and the positioning member are lifted up and are higher than the surface of the bearing seat 11. Then, after the plate is output to the next process, the fourth driving member 310 drives the first gripper 312 and the second gripper 313 to move in opposite directions, so that the upper surfaces of the first limiting member 32 and the second limiting member 33 are not higher than the upper surface of the bearing seat 11.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
