Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and in particular to a clamping component and a suspension frame. Background Technology

[0002] In the chemical treatment process of circuit boards, the circuit boards are usually mounted on a suspension frame and transported by the suspension frame to immerse them in the chemical solution to complete the surface treatment.

[0003] The existing suspension frame uses clamping components to hold circuit boards, but these components cannot fully extend to 90°, preventing the circuit boards from moving horizontally in and out during loading and unloading. In actual operation, multiple clamping components must be opened one by one for step-by-step clamping, severely restricting production line efficiency. Moreover, prolonged contact with liquid chemicals in the clamping components can easily leave residues, but the clamping surfaces are difficult to clean thoroughly when closed. Maintenance requires manually opening each clamping component, significantly increasing downtime for cleaning and affecting the overall utilization rate of the equipment. Utility Model Content

[0004] The purpose of this invention is to propose a clamping component and a suspension frame to improve the clamping efficiency of circuit boards and the overall utilization rate of equipment.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0007] The fastener has a first fixing surface and a second fixing surface arranged adjacent to each other. The first fixing surface is provided with a first clamping fixing position and a first holding position, and the second fixing surface is provided with a first opening clamping fixing position. The first clamping fixing position is located between the first holding position and the first opening clamping fixing position.

[0008] A movable clamp is rotatably connected to the first fixed surface via a rotating shaft. One end of the movable clamp is provided with a second clamping position corresponding to the first clamping position, and a second clamping fixing position located between the rotating shaft and the second clamping position; the other end is provided with a second clamping fixing position.

[0009] The movable clamp has a closed state and an open state. In the closed state, the second clamping fixing position is fixedly connected to the first clamping fixing position, so that the first clamping position and the second clamping position are closed to clamp the clamped part.

[0010] In the open state, the second clamping fixing position is fixedly connected to the first clamping fixing position, so that the first clamping position and the second clamping position are opened at a set angle, the set angle being greater than or equal to 90°.

[0011] As an optional embodiment of the clamping assembly, the fixed connection between the first clamping fixing position and the second clamping fixing position, as well as the fixed connection between the first opening clamping fixing position and the second opening clamping fixing position, are all magnetic connections.

[0012] As an optional embodiment of the clamping assembly, the first clamping fixing position, the first opening clamping fixing position, the second clamping fixing position, and the second opening clamping fixing position are all provided with mounting grooves, and magnets are provided in the mounting grooves.

[0013] As an optional embodiment of the clamping assembly, the first clamping fixing position, the first opening clamping fixing position, the second clamping fixing position, and the second opening clamping fixing position are further provided with a magnet cover, which is connected to the mounting groove to cover the magnet; and the top surface of the magnet cover is flush with the surface of the fixing position.

[0014] As an optional embodiment of the clamping assembly, the movable clamp includes an inclined connecting portion, with both ends of the connecting portion extending parallel to form a clamping fixing end and an opening clamping fixing end. The clamping fixing end is provided with a second clamping position and a second clamping fixing position, and the opening clamping fixing end is provided with a second opening clamping fixing position. The rotating shaft passes through the connecting portion.

[0015] As an alternative to the clamping assembly, two connecting lugs are spaced apart on the first fixing surface, the connecting part is located between the two connecting lugs, and the two ends of the rotating shaft are respectively connected to the two connecting lugs.

[0016] As an optional solution for the clamping assembly, the movable clamps are provided in multiple ways, and multiple sets of the first clamping fixing position, the first clamping position and the first opening clamping fixing position are provided at intervals along the extension direction of the fixing member corresponding to the multiple movable clamps.

[0017] As an alternative to the clamping assembly, both the fixing member and the movable clamp are made of plastic.

[0018] A suspension frame includes a support assembly and a clamping assembly as described in any of the above embodiments. Two sets of clamping assemblies are arranged opposite each other. The support assembly includes a support top plate and a support bottom plate. The top ends of the two sets of clamping assemblies are connected through the support top plate, and the bottom ends are connected through the support bottom plate.

[0019] As an alternative to the suspension frame, the support base plate is provided with a plurality of positioning grooves at intervals, and the bottom of the clamped part is placed in the plurality of positioning grooves.

[0020] The beneficial effects of this utility model are:

[0021] The clamping assembly provided by this utility model includes a fixing member and a movable clamp. The fixing member has a first fixing surface and a second fixing surface arranged adjacent to each other. The first fixing surface has a first clamping fixing position and a first holding position, and the second fixing surface has a first opening clamping fixing position. The movable clamp is rotatably connected to the first fixing surface via a rotating shaft. One end of the movable clamp has a second holding position and a second clamping fixing position, and the other end has a second opening clamping fixing position. By rotating the movable clamp, it switches between a closed state and an open state. When the movable clamp is in the closed state, the second clamping fixing position is fixedly connected to the first clamping fixing position, so that the first holding position and the second clamping position are closed to clamp the clamped object. When the movable clamp is in the open state, the second clamping fixed position and the first clamping fixed position are fixedly connected, allowing the first clamping position and the second clamping position to open at a set angle greater than or equal to 90°. This achieves a fixed unfolding angle greater than or equal to 90° between the first clamping position and the second clamping position when the movable clamp is open. The clamped part can be directly moved horizontally to the first clamping position, avoiding the inefficient operation of traditional clamping components that require one-to-one alignment. Moreover, when the movable clamp is unfolded, the clamping surface and internal structure are fully exposed, facilitating thorough cleaning of residual cleaning fluid, reducing downtime for maintenance, and improving the clamping efficiency of the clamped part and the cleaning efficiency of the clamping components.

[0022] The suspension frame provided by this utility model includes a support component and two sets of clamping components arranged opposite to each other. A clamping space is formed between the support top plate, the two sets of clamping components and the support bottom plate. When all the movable clamps on the two sets of clamping components are fully opened, the clamped part can be moved horizontally into the clamping space. The movable clamps are unfolded at a set angle of greater than or equal to 90°, which facilitates the thorough cleaning of drug residues, improves the clamping efficiency of the clamped part and the cleaning efficiency of the clamping components, and ensures the production line cycle time and the overall utilization rate of the equipment.

[0045] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0047] Example 1:

[0048] like Figure 1 , Figure 2 and Figure 10 As shown, this embodiment provides a clamping assembly 100. When opened, the clamping assembly 100 can form a fixed unfolding angle. When clamping the clamped part 300, there is no need to manually control the unfolding angle of the clamping assembly 100, which makes it easy for the clamped part 300 to be translated horizontally to the clamping assembly 100. Moreover, when cleaning the clamping assembly 100, the clamping surface and internal structure can be fully exposed, which improves the convenience of cleaning.

[0049] The clamping assembly 100 includes a fixing member 1 and a movable clamp 2. The fixing member 1 has a first fixing surface 11 and a second fixing surface 12 arranged adjacent to each other. The first fixing surface 11 is provided with a first clamping fixing position 111 and a first clamping position 112. The second fixing surface 12 is provided with a first opening clamping fixing position 121. The first clamping fixing position 111 is located between the first clamping position 112 and the first opening clamping fixing position 121. The movable clamp 2 is rotatably connected to the first fixing surface 11 via a rotating shaft 3. One end of the movable clamp 2 is provided with a second clamping position 212 corresponding to the first clamping position 112, and a second clamping fixing position 211 located between the rotating shaft 3 and the second clamping position 212; the other end is provided with a second opening clamping fixing position 221. The movable clamp 2 has a closed state and an open state. In the closed state, the second clamping fixing position 211 is fixedly connected to the first clamping fixing position 111, so that the first clamping position 112 and the second clamping position 212 are closed to clamp the clamped part 300. In the open state, the second clamping fixing position 221 is fixedly connected to the first clamping fixing position 121, so that the first clamping position 112 and the second clamping position 212 are opened at a set angle, which is greater than or equal to 90°.

[0050] When the movable clamp 2 is in the open state, the second clamping fixing position 221 and the first clamping fixing position 121 are fixedly connected, so that the first clamping position 112 and the second clamping position 212 open at a set angle greater than or equal to 90°. This achieves a fixed unfolding angle between the first clamping position 112 and the second clamping position 212 when the movable clamp 2 is in the open state. The clamped part 300 can be directly moved horizontally to the first clamping position 112, avoiding the inefficient operation of traditional clamping components 100 which require one-to-one alignment. Moreover, when the movable clamp 2 is in the unfolded state, the clamping surface and internal structure are fully exposed, which facilitates the thorough cleaning of residual medicine, reduces downtime for maintenance, and improves the clamping efficiency of the clamped part 300 and the cleaning efficiency of the clamping component 100.

[0051] Specifically, the fixing member 1 is rectangular, and the first fixing surface 11 and the second fixing surface 12 are adjacent sides of the rectangular fixing member 1 and are perpendicular to each other. When the movable clamp 2 is in the open state, the first clamping position 112 and the second clamping position 212 are opened at 90°. In order to enable the movable clamp 2 to rotate 90°, one side of the rectangular fixing member 1 is recessed, and the second fixing surface 12 is located on the bottom surface of the recessed cavity, so that the angle can be fixed at 90° when the movable clamp 2 is rotated to the open state.

[0052] Of course, in other embodiments, the included angle between the first fixing surface 11 and the second fixing surface 12 can be set to an acute angle, so that when the movable clamp 2 is in the open state, the first clamping position 112 and the second clamping position 212 can be opened at an angle greater than 90°.

[0053] In one embodiment, both the fixing member 1 and the movable clamp 2 are made of plastic. Compared to metal parts, plastic parts have better corrosion resistance and longer durability.

[0054] In one embodiment, the fixed connection between the first clamping fixing position 111 and the second clamping fixing position 211, as well as the fixed connection between the first opening clamping fixing position 121 and the second opening clamping fixing position 221, are all magnetic connections. This magnetic connection improves the opening and closing efficiency of the movable clamp 2, further enhancing the clamping efficiency of the clamped component 300.

[0055] Of course, in other embodiments, the fixed connection can also be a snap-fit ​​or plug-in connection.

[0056] Specifically, such as Figures 3-5 As shown, the first clamping fixing position 111, the first opening clamping fixing position 121, the second clamping fixing position 211, and the second opening clamping fixing position 221 are all provided with mounting grooves 6, and magnets 4 are provided in the mounting grooves 6. When the magnets 4 are placed in the mounting grooves 6, and the first clamping fixing position 111 and the second clamping fixing position 211 are fixedly connected, and the first opening clamping fixing position 121 and the second opening clamping fixing position 221 are fixedly connected, the magnets 4 attract each other to achieve a magnetic connection, resulting in higher connection stability.

[0057] In other embodiments, metal blocks may be provided in the mounting grooves 6 of the first clamping fixing position 111 and the first opening clamping fixing position 121, and magnets 4 may be provided in the mounting grooves 6 of the second clamping fixing position 211 and the second clamping fixing position 211, with the magnets 4 magnetically connected to the metal blocks.

[0058] In one embodiment, the first clamping fixing position 111, the first opening clamping fixing position 121, the second clamping fixing position 211, and the second opening clamping fixing position 221 are further provided with a magnet cover 5. The magnet cover 5 is connected to the mounting groove 6 to cover the magnet 4; and the top surface of the magnet cover 5 is flush with the surface of the fixing position. By covering the magnet 4 with the magnet cover 5, the magnet 4 is protected, preventing the magnet 4 from being affected by corrosion and extending its service life.

[0059] Specifically, both the mounting groove 6 and the magnet 4 are cylindrical, with the outer diameter of the magnet 4 being smaller than the inner diameter of the mounting groove 6. The outer diameter of the magnet cover 5 is matched with the inner diameter of the mounting groove 6, resulting in an interference fit between the magnet cover 5 and the mounting groove 6. The magnet cover 5 is made of plastic, offering superior corrosion resistance, and the magnetic force of the magnet 4 allows it to magnetically connect with another magnet 4 or a metal block through the magnet cover 5.

[0060] In one embodiment, the movable clamp 2 includes an inclined connecting portion 23. The two ends of the connecting portion 23 extend parallel to form a clamping fixing end 21 and an opening clamping fixing end 22. The clamping fixing end 21 has a second clamping position 212 and a second clamping fixing position 211, and the opening clamping fixing end 22 has a second opening clamping fixing position 221. A rotating shaft 3 passes through the connecting portion 23. The inclined connecting portion 23 of the movable clamp 2, together with the parallel extending clamping fixing end 21 and the opening clamping fixing end 22, forms a lever structure, achieving torque balance through the fulcrum of the rotating shaft 3. When the inclined connecting portion 23 rotates, the clamping fixing end 21 and the opening clamping fixing end 22 move in opposite directions, using the lever principle to reduce the resistance of the opening and closing operation and ensure precise locking of the 90° opening angle. The parallel extending fixing ends ensure that the clamping force is evenly distributed along the axial direction of the connecting portion 23, avoiding local stress concentration and improving the durability of the clamping assembly 100. Furthermore, when the movable clamp 2 is in the open state, the inclined connecting portion 23 completely exposes the clamping surface, facilitating the thorough removal of residual drug crystals from the clamping surface.

[0061] Specifically, two connecting lugs 13 are spaced apart on the first fixed surface 11, and the connecting part 23 is located between the two connecting lugs 13. The two ends of the rotating shaft 3 are respectively connected to the two connecting lugs 13. The connecting part 23 is provided with a through hole 231, and each of the two connecting lugs 13 is provided with a connecting hole 131. One end of the rotating shaft 3 is provided with a limit head 31, and the other end is provided with a slot. After the other end of the rotating shaft 3 passes through one connecting hole 131, the through hole 231 and the other connecting hole 131 in sequence, the retaining spring 7 is engaged in the slot, so that the rotating shaft 3 can be fixed to the two connecting lugs 13, and the movable clamp 2 can rotate relative to the rotating shaft 3.

[0062] In one embodiment, multiple movable clamps 2 are provided, and multiple sets of first clamping fixing positions 111, first holding positions 112 and first opening clamping fixing positions 121 are provided at intervals along the extension direction of the fixing member 1 corresponding to the multiple movable clamps 2. This arrangement enables the clamping assembly 100 to clamp multiple points of the clamped member 300, ensuring the stability of the clamped member 300.

[0063] Example 2:

[0064] like Figures 6-13 As shown, this embodiment provides a suspension frame applied in a pharmaceutical liquid treatment device. The clamped component 300 is a circuit board. The circuit board is suspended on the suspension frame, and the circuit board is transferred by the suspension frame to immerse it in the pharmaceutical liquid to complete the surface treatment.

[0065] The suspension frame includes a support assembly and a clamping assembly 100 provided in Embodiment 1. Two sets of clamping assemblies 100 are arranged opposite each other. The support assembly includes a top support plate 201 and a bottom support plate 202. The top ends of the two sets of clamping assemblies 100 are connected through the top support plate 201, and the bottom ends are connected through the bottom support plate 202.

[0066] Specifically, the two ends of the top support plate 201 are fixedly connected to the top ends of the two sets of clamping assemblies 100 by screws, and the two ends of the bottom support plate 202 are fixedly connected to the bottom ends of the two sets of clamping assemblies 100 by snap-fit ​​or screws.

[0067] In this embodiment, by setting two sets of clamping components 100, the opposite sides of the circuit board can be clamped and fixed. A clamping space is formed between the supporting top plate 201, the two sets of clamping components 100, and the supporting bottom plate 202. When all the movable clamps 2 on the two sets of clamping components 100 are fully opened, the circuit board can be moved horizontally into the clamping space, and the movable clamps 2 are unfolded at a fixed angle, which facilitates the thorough cleaning of residual medicine, improves the clamping efficiency of the circuit board and the cleaning efficiency of the clamping components 100, and ensures the production line cycle time and the overall utilization rate of the equipment.

[0068] In one embodiment, a plurality of positioning grooves 2021 are provided at intervals on the support base plate 202, and the bottom of the clamped member 300 is placed in the plurality of positioning grooves 2021. When installing the circuit board, the circuit board is moved to abut against the first fixed surface 11 of the two clamping components 100, the bottom of the circuit board is placed in the plurality of positioning grooves 2021, and then the plurality of movable clamps 2 are rotated in sequence to the closed state, so that the circuit board can be installed on the suspension frame.

[0069] Specifically, three positioning blocks are spaced apart on the support base plate 202. The bottom of the positioning blocks is engaged with the support base plate 202, and the top is provided with a positioning groove 2021. The positioning groove 2021 is a V-shaped groove, which can clamp the opposite side walls of the circuit board to ensure the stability of positioning.

[0070] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
