Description

Technical Field

[0001] This application belongs to the field of machining equipment technology, and more specifically, relates to a clamping and positioning mechanism and machining equipment. Background Technology

[0002] Currently, PCB board drilling is typically done manually. The boards are loaded onto the drilling machine's worktable, and then holes are drilled manually, with several fixing pins inserted for positioning. However, this process often requires handling boards of different sizes. If drilling and pin insertion are repeated for each size, it consumes significant time and manpower and cannot be integrated with subsequent automated feeding equipment. Therefore, there is an urgent need for a device that can guide, position, and clamp PCB boards of different sizes. Utility Model Content

[0003] The purpose of this application is to provide a clamping and positioning mechanism and processing equipment to guide, position and clamp and fix plates of different sizes in multiple directions.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, this application provides a clamping and positioning mechanism, including a worktable, a pneumatic clamp assembly, and a first clamping assembly. The worktable is used to support a sheet metal. The pneumatic clamp assembly is disposed on the worktable and is used to guide and position the sheet metal in a first direction. The first clamping assembly is disposed on the worktable and clamps the sheet metal in the first direction. The first clamping assembly includes a first clamping component and a second clamping assembly. The first clamping component includes at least two sets of first clamping components arranged parallel to each other in a second direction. The second clamping assembly includes at least two sets of second clamping components spaced apart in the second direction, and the at least two sets of second clamping components are staggered in the first direction, so that the first clamping assembly and the second clamping assembly have at least two clamping ranges in the first direction.

[0005] In this design, the worktable provides an installation and load-bearing reference for each component, ensuring the overall structural stability. The pneumatic clamp assembly is guided and positioned in the first direction to prevent initial offset of the sheet metal, providing a foundation for subsequent clamping. The two sets of first clamping elements and the second clamping assembly work together to clamp the material, forming at least two clamping ranges. The first clamping assembly can adapt to sheet metal of different sizes without replacing parts, improving versatility, reducing adjustment time, and ensuring processing accuracy.

[0006] In one possible design of the first aspect, the first clamping member includes a first slide groove and a first clamping component, and the second clamping member includes a second slide groove and a second clamping component. The first clamping component is slidably connected in the first slide groove, and the second clamping component is slidably connected in the second slide groove. The first slide groove and the second slide groove are offset from each other in a first direction.

[0007] In this design, the first clamping component and the second clamping component are slidably connected to their corresponding slides, allowing for flexible adjustment of the clamping position to accommodate different sized plates. The first slide and the second slide are offset in the first direction to achieve cooperation between the first clamping component and the second clamping component in the first direction.

[0008] In one possible design of the first aspect, the first clamping assembly includes two sets of first clamping members, the second clamping member includes two sets of second clamping members, and the first clamping assembly and the second clamping assembly have two clamping ranges in a first direction.

[0009] In this design, the first clamping assembly has two sets of first clamping members, and the second clamping assembly has two sets of second clamping members. The first and second clamping members can clamp correspondingly, and the two sets of first and second clamping members cooperate to form two clamping ranges for the first and second clamping assemblies. The two sets of clamping members can adapt to different sizes of plates, and the clamping force on both sides is balanced, which helps to prevent plate deformation.

[0010] In one possible design of the first aspect, a set of first clamping elements and a set of second clamping elements are provided on both sides of the air clamp assembly.

[0011] In this design, each set of first and second clamping elements on both sides of the pneumatic clamp assembly provides clamping force independently to the corresponding side. The symmetrical layout ensures that the clamping force is evenly distributed on both sides of the pneumatic clamp assembly. The guiding and positioning of the pneumatic clamp assembly works in conjunction with the clamping elements on both sides to balance the force on the plate, avoiding offset caused by clamping on one side. At the same time, it can expand the clamping coverage area, adapt to plates of different sizes, and improve positioning stability and clamping reliability.

[0012] In one possible design of the first aspect, a second clamping assembly is also included, which is disposed on the worktable and is used to clamp the sheet metal in a second direction.

[0013] In this design, the second clamping assembly clamps in the second direction, supplementing the inadequacy of the first clamping and restricting the displacement of the sheet metal in the second direction. Together with the first clamping assembly, it forms a vertical, bidirectional fixation, restricting the sheet metal's displacement in the plane from multiple directions. This prevents displacement of the sheet metal due to vibration or impact during processing, thus meeting the requirements of high-precision machining.

[0014] In one possible design of the first aspect, the second clamping assembly includes a plurality of third clamping components, which are spaced apart on the worktable along a first direction.

[0015] In this design, multiple third clamping components are spaced apart along the first direction, employing a spaced layout that allows for flexible selection of clamping points based on the length of the sheet material. Multiple clamping points disperse the clamping force, preventing excessive local pressure from damaging the sheet material, while simultaneously enhancing the overall fixing effect, improving clamping stability, and ensuring the sheet material remains flat during processing.

[0016] In one possible design of the first aspect, the third clamping assembly includes two sets of third clamping members arranged parallel to each other in the second direction, and the pneumatic clamping assembly is located between the two sets of third clamping members.

[0017] In this design, two sets of third clamping members are arranged parallel to each other in the second direction, which can form a balanced clamping force on the plate from both sides. The guide positioning works in conjunction with the two-sided third clamping members to ensure that the plate does not shift during clamping and that the force is balanced, simplifying the positioning and clamping process, improving operational efficiency, and ensuring clamping stability in the second direction.

[0018] In one possible design of the first aspect, the air clamp assembly includes two guide rods that form a guide groove to guide the sheet metal.

[0019] In this design, the guide groove formed by two guide rods provides a conveying path for the sheet material, guiding it into the positioning area and reducing offset during conveying. The inlet can be designed as a flared opening to improve the feeding error tolerance. This structure is simple, reliable, and has low maintenance costs. When used in conjunction with the clamping assembly, it reduces the difficulty of subsequent positioning, provides an initial positioning basis for the clamping assembly, and improves overall positioning efficiency.

[0020] In one possible design of the first aspect, the pneumatic clamp assembly further includes a first positioning member and a second positioning member, which are disposed on the worktable and located between two guide rods. The first positioning member and the second positioning member are used to engage with pins on the plate.

[0021] In this design, the first and second positioning components are located between the guide rods and cooperate with the pins on the sheet metal to achieve sheet metal positioning. The positioning components, positioned between the guide rods, allow for rapid positioning of the guided sheet metal. Furthermore, the cooperation between the positioning components and the pins helps reduce positioning errors, thereby ensuring machining accuracy.

[0022] Secondly, this application provides a processing device, including multiple processing spindles, a crossbeam, a base, and a clamping and positioning mechanism provided by the first aspect and any of its design embodiments. The clamping and positioning mechanism is mounted on the base, the crossbeam is mounted on the base, and the multiple processing spindles are mounted on the crossbeam and are used to process the sheet metal when the clamping and positioning mechanism positions the sheet metal.

Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0033] To address the aforementioned technical problems, embodiments of this application provide a clamping and positioning mechanism. (See reference...) Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a clamping and positioning mechanism for conveying materials, provided in an embodiment of this application. Figure 2 This is a schematic diagram of a clamping and positioning mechanism provided in an embodiment of this application.

[0034] like Figure 1 and Figure 2 As shown, this application provides a clamping and positioning mechanism, including a worktable 110, a pneumatic clamp assembly 120, and a first clamping assembly 131. The worktable 110 is used to support a sheet metal 200. The pneumatic clamp assembly 120 is disposed on the worktable 110 and is used to guide and position the sheet metal 200 in a first direction. The first clamping assembly 130 is disposed on the worktable 110 and clamps the sheet metal 200 in the first direction. The first clamping assembly 130 includes a first clamping assembly 131 and a second clamping assembly 132. The first clamping assembly 131 includes at least two sets of first clamping members 1311 arranged parallel to each other in a second direction. The second clamping assembly 132 includes at least two sets of second clamping members 1321 arranged spaced apart in a second direction, and the at least two sets of second clamping members 1321 are staggered in the first direction, so that the first clamping assembly 131 and the second clamping assembly 132 have at least two clamping ranges in the first direction.

[0035] In this embodiment, the workbench 110 serves as the overall load-bearing component, not only supporting the PCB board 200 but also providing a stable mounting platform for the pneumatic clamp assembly 120 and the first clamping assembly 130, ensuring no relative displacement of the components during processing to guarantee structural rigidity. The pneumatic clamp assembly 120 is located in the middle of the workbench 110 and, through cooperation with pins on the board 200, guides and positions the board 200 in a first direction, determining the initial position for subsequent clamping operations.

[0036] The first clamping assembly 130 is disposed on the worktable 110, and includes a first clamping component 131 and a second clamping component 132. The first clamping component 131 includes at least two sets of first clamping members 1311 distributed parallel to each other in the second direction, and the second clamping component 132 includes at least two sets of second clamping members 1321 distributed at intervals and staggered in the second direction. The two sets of clamping components are symmetrically installed on both sides of the pneumatic clamping assembly 120. The first clamping members 1311 and the second clamping members 1321 cooperate to form at least two sets of combinations. The two sets of combinations form different clamping ranges in the first direction to facilitate clamping materials of different sizes.

[0037] In this embodiment, the initial positioning of the pneumatic clamp assembly 120 can prevent the board material 200 from shifting during clamping. The first clamping assembly 131 and the second clamping assembly 132 form at least two clamping ranges due to the positional design of the first clamping member 1311 and the second clamping member 1321. They can be adapted to different specifications of PCB boards 200 without replacing parts, improving the versatility of the mechanism and reducing the specification switching time. At the same time, multiple clamping members work together to enhance the clamping stability of the board material 200 to ensure drilling accuracy.

[0038] It should be noted that the first direction can refer to the width direction of the board 200, and the second direction can refer to the length direction of the board 200; or, the first direction can refer to the length direction of the board 200, and the second direction can refer to the width direction of the board 200. In the embodiments of this application, the first direction and the second direction are referred to as... Figure 1 The direction indicated in the text.

[0039] like Figure 2 As shown, in one embodiment of this application, the first clamping member 1311 includes a first sliding groove 13111 and a first clamping component 13112, and the second clamping member 1321 includes a second sliding groove 13211 and a second clamping component 13212. The first clamping component 13112 is slidably connected in the first sliding groove 13111, and the second clamping component 13212 is slidably connected in the second sliding groove 13211. The first sliding groove 13111 and the second sliding groove 13211 are offset from each other in a first direction.

[0040] In this embodiment, a sliding connection design is adopted. The first clamping component 13112 and the second clamping component 13212 can move flexibly along the corresponding first slide groove 13111 and second slide groove 13211, respectively. The clamping position is adjusted according to the size of the plate 200 to ensure that it fits the edge of the plate 200, avoiding the problem that the fixed position cannot adapt to various specifications. At the same time, the first clamping component 13112 slides in the first slide groove 13111, and the second clamping component 13212 slides in the second slide groove 13211. The fixed sliding trajectory can prevent the first clamping component 13112 and the second clamping component 13212 from shifting, so as to ensure accuracy. The first slide groove 13111 and the second slide groove 13211 are staggered in the first direction, so that the first clamping component 13112 and the second clamping component 13212 can cooperate to form a clamping range to clamp the plate 200 in the first direction.

[0041] In this embodiment of the application, at least two sets of second clamping members 1321 are staggered in the first direction, indicating that at least two second slide grooves 13211 are staggered in the first direction. At least two sets of second clamping members 13212 disposed in the second slide grooves 13211 cooperate with at least two sets of first clamping members 13112 disposed in the first slide grooves 13111, so that the first clamping assembly 131 and the second clamping assembly 132 have at least two clamping ranges in the first direction.

[0042] At least two sets of second clamping members 1321 are staggered in the first direction, determining the difference in clamping range between at least two sets of first clamping members 13112 and at least two sets of second clamping members 13212. Specifically, the clamping range formed by the second clamping member 13212 located further out of the second slide groove 13211 and the first clamping member 13112 is larger, while the clamping range formed by the second clamping member 13212 located further in the second slide groove 13211 and the first clamping member 13112 is smaller. The coordinated action of multiple sets of clamping members achieves both precise adjustment of the clamping position and stable maintenance of differentiated clamping ranges. This allows for the clamping of different 200mm sheet metal sizes without the need for additional component replacement, reducing equipment adjustment costs and ensuring the long-term reliability of the sliding structure.

[0043] like Figure 2 As shown, in one embodiment of this application, the first clamping assembly 131 includes two sets of first clamping members 1311, and the second clamping member 1321 includes two sets of second clamping members 1321. The first clamping assembly 131 and the second clamping assembly 132 have two clamping ranges in a first direction.

[0044] In this embodiment, the number of clamping members in the first clamping assembly 131 and the second clamping assembly 132 is limited. The first clamping assembly 131 includes two sets of first clamping members 1311, which are respectively installed on both sides of the pneumatic clamping assembly 120 and are distributed parallel to each other in the second direction, with consistent sliding strokes. The second clamping assembly 132 includes two sets of second clamping members 1321, which are also installed on both sides of the pneumatic clamping assembly 120 and are spaced apart in the second direction. The two sets of first clamping members 1311 are symmetrically installed on both sides of the pneumatic clamping assembly 120 near the front end, and the two sets of second clamping members 1321 are symmetrically installed on both sides of the pneumatic clamping assembly 120 near the rear end. The first clamping members 1311 and second clamping members 1321 on the same side of the pneumatic clamping assembly 120 cooperate with each other to clamp the plate 200 in the first direction. Furthermore, the first slide groove 13111 and the second slide groove 13211 are offset in the first direction to ensure that the clamping ranges of the two sets of clamping components do not overlap, so as to achieve clamping of plates 200 of different sizes.

[0045] The above structure forms two distinct clamping ranges, eliminating the need for additional clamping modules to reduce the complexity of the mechanism. At the same time, the clamping components distributed on both sides ensure that the plate 200 is subjected to balanced force in the first direction, reducing processing vibration and displacement to ensure drilling accuracy, and adapting to the automated production needs of various PCB plate sizes 200.

[0046] like Figure 2 As shown in one embodiment of this application, a set of first clamping members 1311 and a set of second clamping members 1321 are provided on both sides of the pneumatic clamp assembly 120. The first clamping member 1311 and the second clamping member 1321 on the left side of the pneumatic clamp assembly 120 are respectively installed at the front and rear ends of the left side region of the workbench 110, corresponding to the clamping requirements on the left side of the plate 200. The first clamping member 1311 and the second clamping member 1321 on the right side of the pneumatic clamp assembly 120 are respectively installed at the front and rear ends of the right side region of the workbench 110, corresponding to the clamping requirements on the right side of the plate 200. Each clamping member is connected to the workbench 110 through a corresponding sliding groove to achieve independent sliding adjustment. The guide trajectory of the pneumatic clamping assembly 120 is consistent with the clamping direction of the clamping members on both sides. After the plate 200 is guided and positioned by the pneumatic clamping assembly 120, the corresponding first clamping member 1311 or second clamping member 1321 on both sides can move synchronously towards the plate 200 to achieve clamping, so that the plate 200 is subjected to balanced force on both sides in the first direction, avoiding the plate 200 from shifting or deforming due to clamping on one side. When processing a smaller plate 200, the first clamping member 1311 and the second clamping member 1321 on the left side of the pneumatic clamping assembly 120 clamp. When processing a larger plate 200, the first clamping member 1311 and the second clamping member 1321 on the right side of the pneumatic clamping assembly 120 clamp.

[0047] like Figure 2 As shown, in one embodiment of this application, a second clamping assembly 140 is also included. The second clamping assembly 140 is disposed on the worktable 110 and is used to clamp the plate 200 in a second direction.

[0048] This embodiment also includes a second clamping assembly 140, which is disposed on both sides of the worktable 110, coplanar with the first clamping assembly 130 and without spatial interference. The first clamping assembly 130 extends along a first direction, and the second clamping assembly 140 extends along a second direction. The worktable 110, the pneumatic clamp assembly 120, and the first clamping assembly 130 maintain their original structure and connection relationship. The worktable 110 provides overall load-bearing, the pneumatic clamp assembly 120 completes the first direction guidance and positioning, the first clamping assembly 130 achieves clamping in the first direction, and the second clamping assembly 140 clamps the board 200 in the second direction. Through bidirectional constraint, the degree of freedom of the board 200 in the plane of the worktable 110 is restricted, avoiding the board 200 from shifting due to tool impact or vibration during PCB drilling. At the same time, bidirectional clamping does not require manual assistance for fixing and can be directly connected to automated feeding equipment, solving the problem of time-consuming and labor-intensive manual positioning, thus greatly improving production efficiency and meeting the continuous processing requirements of automated production lines.

[0049] like Figure 2 As shown, in one embodiment of this application, the second clamping assembly 140 includes a plurality of third clamping components 141, which are spaced apart on the worktable 110 along a first direction.

[0050] In this embodiment, the second clamping assembly 140 includes a plurality of third clamping components 141, which are spaced apart along a first direction on both sides of the worktable 110, and each third clamping component 141 can work independently. The plurality of third clamping components 141 are spaced apart along the first direction on the worktable 110, and can be evenly distributed along the first direction. Through this spaced distribution design, the third clamping components 141 can distribute the clamping force in the second direction to multiple points, avoiding excessive pressure at a single clamping point that could cause edge deformation of the PCB board 200, and preventing damage caused by excessive local pressure due to the thinness of the PCB board 200, thus ensuring the flatness of the board 200 after processing.

[0051] like Figure 2 As shown, in one embodiment of this application, the third clamping assembly 141 includes two sets of third clamping members 1411, which are arranged in parallel in the second direction, and the air clamp assembly 120 is located between the two sets of third clamping members 1411.

[0052] This embodiment defines each third clamping assembly 141 as including two sets of third clamping members 1411, which are distributed parallel to each other in the second direction. The pneumatic clamping assembly 120 is located in the middle of all the third clamping assemblies 141. Taking two sets of third clamping assemblies 141 distributed along the first direction as an example, the two sets of third clamping members 1411 in each set of third clamping assemblies 141 are respectively installed on both sides of the workbench 110, symmetrically arranged with the pneumatic clamping assembly 120 as the center. Multiple third clamping assemblies 141 are still spaced apart along the first direction. After the plate 200 is guided and positioned by the pneumatic clamping assembly 120, the two sets of third clamping members 1411 of each set of third clamping assemblies 141 can simultaneously move towards both sides of the plate 200 in the second direction to achieve clamping. The two sets of third clamping members 1411 are symmetrically distributed in parallel along the second direction, ensuring that the plate 200 is subjected to balanced clamping force on both sides. This prevents excessive clamping force on one side from causing the plate 200 to twist, and ensures the fit between the plate 200 and the worktable 110, thereby improving drilling position accuracy. The pneumatic clamp assembly 120 is located in the middle position, shortening the movement distance of the plate 200 from guide positioning to clamping in the second direction, reducing positional deviation. Simultaneously, the parallel third clamping members 1411 can have their spacing adjusted by sliding, allowing them to adapt to plates 200 of different widths without replacing parts, maintaining the mechanism's versatility and reducing operating costs.

[0053] It should be noted that the clamping ends of the first clamping member 1311, the second clamping member 1321, and the second clamping member 1321 in this embodiment can all adopt a mushroom-head structure design. This structure can increase the contact area with the edge of the plate 200, avoiding excessive local pressure that could damage the edge of the plate 200. At the same time, the mushroom head can press the plate 200 firmly, improving clamping stability.

[0054] refer to Figure 3 , Figure 3 This is a schematic diagram of the structure of the pneumatic clamp assembly 120 in a clamping and positioning mechanism provided in an embodiment of this application. Figure 3 As shown, in one embodiment of this application, the air clamp assembly 120 includes two guide rods 121, which form a guide groove to guide the plate 200.

[0055] Two guide rods 121 are arranged in parallel on the upper surface of the worktable 110. The two guide rods 121 can move to form a guide groove. The inlet end of the guide groove can adopt a flared design, that is, the inlet end of the two guide rods 121 is tilted outward at a certain angle to expand the inlet range and improve the feeding error tolerance.

[0056] The guide groove formed by the two guide rods 121 provides a clear movement trajectory for the plate 200, preventing the plate 200 from shifting during transportation, reducing the difficulty of subsequent positioning adjustments, and improving positioning efficiency. Using two guide rods 121 to form the guide groove results in a simple structure, high reliability, and low maintenance costs.

[0057] like Figure 3 As shown, in one embodiment of this application, the air clamp assembly 120 further includes a first positioning member 122 and a second positioning member 123. The first positioning member 122 and the second positioning member 123 are disposed on the workbench 110 and are located between two guide rods 121. The first positioning member 122 and the second positioning member 123 are used to cooperate with the pins on the plate 200.

[0058] The first positioning element 122 and the second positioning element 123 can be fixedly connected to the worktable 110 and are located between the two guide rods 121, arranged back and forth along the first direction. The first positioning element 122 and the second positioning element 123, located between the guide rods 121, can receive the plate 200 conveyed by the guide groove, preventing the plate 200 from needing to move a long distance after being guided to its position, thus reducing positional deviation. The back-and-forth arrangement of the first positioning element 122 and the second positioning element 123 can limit the displacement of the plate 200 in the first direction through two positioning points, preventing the plate 200 from moving along the first direction and achieving initial fixation in the plane.

[0059] The first positioning component 122 and the second positioning component 123 can be equipped with tapered guide holes. The tapered guide holes can guide the pin holes on the plate 200 to quickly fit into the positioning components, reducing positioning time and improving positioning efficiency.

[0060] In actual operation, when the sheet metal 200 is conveyed to the preset area along the guide groove, the pins on the sheet metal 200 are initially aligned with the first positioning member 122 and the second positioning member 123 under the limiting effect of the guide groove. Subsequently, the sheet metal 200 moves downward along the thickness direction (perpendicular to the table surface), and the pins on the sheet metal 200 are inserted into the positioning holes under the action of the tapered guide holes, completing the positioning of the sheet metal 200. At this time, the displacement of the sheet metal 200 in the plane is restricted, providing a basis for the clamping of the clamping assembly and subsequent processing.

[0061] The first positioning component 122 and the second positioning component 123, in conjunction with the pins on the sheet metal 200, form a mechanical positioning structure with high positioning accuracy, which is beneficial for meeting the high-precision drilling requirements of the sheet metal 200. The first positioning component 122 and the second positioning component 123 are located between the guide rods 121, which allows the guided sheet metal 200 to be quickly positioned, reducing the time between processes and improving production efficiency.

[0062] In one embodiment of this application, a processing device is also provided. The device includes multiple processing spindles, a crossbeam, a base, and a clamping and positioning mechanism as described in any of the above embodiments. The clamping and positioning mechanism is mounted on the base, the crossbeam is mounted on the base, and the multiple processing spindles are mounted on the crossbeam and are used to process the plate 200 when the clamping and positioning mechanism positions the plate 200.

[0063] The base serves as the basic frame of the equipment, supporting the clamping and positioning mechanism and the crossbeam. This ensures the rigidity and stability of the overall structure, preventing positioning deviations caused by equipment vibration during processing. It also provides a unified installation benchmark for all components to ensure relative positional accuracy. The crossbeam, mounted on the base and spanning above the clamping and positioning mechanism, supports multiple machining spindles and provides movement guidance, allowing them to slide along a primary direction to cover the entire processing area of ​​the sheet metal 200. Multiple machining spindles are mounted on the crossbeam and spaced along its length. They are used to drill holes in the sheet metal 200 after it has been clamped and positioned by the clamping and positioning mechanism. Multiple spindles can simultaneously process different holes or collaboratively process different areas of the same sheet metal 200 to improve processing efficiency. All components are linked through a control system. After the clamping and positioning mechanism completes the clamping and positioning of the sheet metal 200, it sends a signal to the spindle control system, causing the spindle to start and perform drilling according to a preset program.
