Description

Technical Field

[0001] This utility model relates to the field of material storage, and in particular to a buffer rack and an automatic buffer device. Background Technology

[0002] In flat wire stator motors, flat wires are processed into U-shapes according to different length requirements and then sequentially inserted into winding fixtures via an automatic wire insertion device. Because the flat wire stator winding has a multi-layer structure, and to ensure production line flexibility, the same forming machine typically needs to produce multiple specifications of hairpin wire. When forming abnormalities occur, the poorly formed hairpin wire needs to be discharged. Simultaneously, because the original sequence is disrupted, to ensure normal production, existing formed hairpin wires need to be retrieved from the hairpin wire buffer rack and added to the forming machine to prevent further disruption of the original sequence.

[0003] In the existing technology, different models of hairpin wires have different sizes, and different buffer racks are required for different models of hairpin wires, which makes it inconvenient to pick up the wires. Utility Model Content

[0004] This application provides a buffer rack and an automatic buffer device, which can achieve the purpose of quickly changing materials and improve production efficiency.

[0005] To this end, the first aspect of this application provides a buffer rack, the buffer rack comprising: a frame; a storage component, the storage component including a mounting plate and a storage rack movably mounted on the mounting plate; a height adjustment component, the height adjustment component being located between the mounting plate and the frame to adjust the height of the storage component; and a drive component, the drive component being located below the mounting plate for driving the storage rack to rise and fall.

[0006] In this solution, due to differences in material size, the convenient retrieval height varies for different materials. By installing a height adjustment component between the mounting plate and the frame, the overall height of the storage component can be dynamically adjusted according to the production line's needs. The height of the storage component can be increased to facilitate material retrieval, or decreased, which shortens the stroke of the drive component, thereby improving material retrieval efficiency and further contributing to energy savings. Through the coordinated action of the height adjustment component and the drive component, the production line's operating efficiency can be significantly improved.

[0007] In one possible design, the height adjustment assembly includes a fixing member and at least one pad, with the at least one pad located between the fixing member and the frame, the fixing member being used for detachably connecting the mounting plate and the pad.

[0008] In this solution, the height adjustment component is modularized, comprising a fixing element and at least one pad. This allows for flexible adjustment of the mounting plate height by replacing pads of different sizes or changing the number of pads, reliably meeting the needs of various working conditions. Furthermore, the fixing element detachably connects the mounting plate and the pad. With the mounting plate reliably secured, the pad can be flexibly detached from the fixing element, further improving the efficiency of pad replacement and installation.

[0009] In one possible design, the fastener includes a first clamping portion and a second clamping portion, the mounting plate is clamped between the first clamping portion and the second clamping portion, and the first clamping portion, the second clamping portion and the mounting plate are connected by a first fastener.

[0010] In this solution, by setting the first clamping part and the second clamping part to clamp the mounting plate together, and connecting the three parts by the first fastener, a rigid fixing structure for the mounting plate can be formed after fastening, which can effectively prevent the mounting plate from displacing or vibrating when subjected to external loads. At the same time, the detachable connection of the first fastener allows for quick release of clamping constraints. When changing the pad to adjust the height, only the first fastener needs to be removed, without adjusting the other components, which can significantly improve maintenance efficiency and maintain the original positioning accuracy of the system.

[0011] In one possible design, at least one of the pads is located below the fixing member, and the first clamping part, the mounting plate, the second clamping part, the pad, and the frame are connected by a second fastener.

[0012] In this solution, by placing at least one pad below the fixing component, and connecting the first clamping part, mounting plate, second clamping part, pad, and frame through a second fastener, the components can be integrated into one unit, effectively preventing relative displacement between parts. Simultaneously, the connection of the first clamping part, mounting plate, second clamping part, pad, and frame through the second fastener also improves the stability of each component under impact. This connection method allows for quick replacement of the entire module simply by releasing the second fastener during disassembly, maintaining the integrity of the buffer rack's main structure and the positioning accuracy during installation.

[0013] In one possible design, the first clamping portion includes a protrusion that extends along the height direction of the buffer rack, and the second clamping portion abuts against the top of the protrusion, so that the first clamping portion and the second clamping portion form a clamping space for clamping the mounting plate.

[0014] In this design, the second clamping part abuts against the top of the protrusion, and the two together form a clamping space to wrap the mounting plate. The surfaces of the protrusion and the second clamping part that abut against each other can form a rigid support reference surface to prevent displacement when the second clamping part is pressed. The wrapping constraint of the clamping space on the mounting plate can effectively improve the torsional resistance of the mounting plate and further improve the stability of the mounting plate when it is fixed.

[0015] In one possible design, the second clamping part has a positioning groove, and the height adjustment assembly further includes a positioning element, which includes a connecting part and a head. The connecting part is detachably connected to the mounting plate, and the head is embedded in the positioning groove.

[0016] In this design, by providing a positioning groove in the second clamping part and detachably connecting the connecting part of the positioning member to the mounting plate, with the head of the positioning member embedded in the positioning groove, the connection reliability between the mounting plate and the fixing member is further improved. Simultaneously, the head embedded in the positioning groove constrains the displacement of the mounting plate, preventing slippage of the second clamping part relative to the mounting plate under vibration. The connecting part of the positioning member is stably connected to the mounting plate. When the mounting plate is connected to the second clamping part, the head cooperates with the positioning groove to achieve accurate positioning. Disassembly is convenient; simply moving the mounting plate along the height direction disengages the head from the positioning groove. Therefore, in this embodiment, by providing the positioning member and positioning groove, the assembly and disassembly efficiency of the mounting plate can be significantly improved while maintaining positioning accuracy.

[0017] In one possible design, the drive assembly includes a cylinder and a guide rail mounted on the frame and extending along a first direction, the cylinder being slidably mounted on the guide rail, a portion of the storage rack being located above the mounting plate and another portion being located below the mounting plate, and the cylinder being connected to the storage rack.

[0018] In this design, the two ends of the storage rack can be located on both sides of the mounting plate, meaning the storage rack can pass through the mounting plate, allowing the mounting plate to support at least part of the storage rack and ensuring the storage rack's position is stable and reliable. The guide rail is set on the frame and extends along the first direction. The cylinder is slidably mounted on the guide rail, allowing the cylinder to move along the guide rail in the first direction. The cylinder can drive the storage rack at different positions along the first direction, improving adaptability under different working conditions.

[0019] In one possible design, a connecting rod and a connecting plate are connected below the storage rack. The mounting plate has a through hole, along which the connecting rod can move. The end of the connecting plate opposite to the connecting rod is used to connect to the cylinder.

[0020] In this solution, a connecting rod and a connecting plate are installed below the storage rack, and the connecting rod moves along the through hole of the mounting plate. At the same time, the end of the connecting plate away from the connecting rod can be connected to a cylinder. The cylinder pushes the connecting plate and the connecting rod to move up and down along the through hole. The connection rod and the through hole can play a guiding role, so that the storage rack can move along a predetermined movement path, preventing the storage rack from tilting during movement, and improving the stability and reliability of the storage rack operation.

[0021] In one possible design, the buffer rack further includes an elastic element that is sleeved onto the connecting rod.

[0022] In this design, the elastic element fitted onto the connecting rod is compressed under the pressure of the connecting plate and the mounting plate when the cylinder drives the connecting rod upward. When the cylinder stops working and resets, the elastic element's rebound force drives the connecting plate to automatically reset the connecting rod, thus automatically resetting the storage rack. Therefore, the storage rack does not require other components to drive its reset, simplifying the structure of the buffer rack. Furthermore, the elastic element also acts as a buffer during the cylinder's movement of the connecting plate towards the mounting plate, reducing the impact during this process. Additionally, when the cylinder drives other storage racks, there is no interference between different racks, preventing interference with the card issuing line retrieval and further improving the stability of the buffer rack operation.

[0023] A second aspect of this application provides an automatic caching device, which includes the caching rack described above.

[0024] Because this buffer rack can improve buffer efficiency, it can improve the efficiency of the automatic buffer device.

[0025] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0029] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0030] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0031] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0032] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0033] In flat wire stator motors, flat wires are processed into U-shapes according to different length requirements and then sequentially inserted into winding fixtures using an automatic wire insertion device. Because the flat wire stator winding has a multi-layered structure, and to ensure production line flexibility, a single forming machine typically needs to produce multiple specifications of hairpin wire. Based on these reasons and the inherent characteristics of the wire forming machine structure, the hairpin wires need to be pre-formed sequentially according to a specific order. If an abnormality occurs during the forming process, the poorly formed hairpin wire needs to be discarded, and the correct hairpin wire needs to be replaced.

[0034] This application provides an automatic buffer device, including a controller, a buffer rack, and a robotic arm. The buffer rack is used to store hairpin threads of various specifications. When a defective hairpin thread is found, the controller controls the robotic arm to retrieve the hairpin thread from the buffer rack and add it to the existing forming sequence. In other embodiments, the automatic buffer device can also be used to store other materials. This application does not specifically limit the application of the automatic buffer device.

[0035] This application provides a buffer rack, such as Figure 1 As shown, the buffer rack includes a frame 4, a storage component 1, a height adjustment component 3, and a drive component. The storage component 1 includes a mounting plate 11 and a storage rack 12 movably mounted on the mounting plate 11. The height adjustment component 3 can be located between the mounting plate 11 and the frame 4 to adjust the height of the storage component 1. The drive component is located below the mounting plate 11 and is used to drive the storage rack 12 to rise and fall. It should be noted that the buffer rack in this embodiment can be used not only to store hair clips but also to store other materials. The following description uses the buffer rack for storing hair clips as an example.

[0036] In this embodiment, by setting a height adjustment component 3 between the mounting plate 11 and the frame 4, the overall height of the storage component 1 can be dynamically adjusted according to the needs of the production line. The height of the storage component 1 can be increased by the height adjustment component 3 to facilitate the retrieval of the card issuing line, and it can also be decreased, thus shortening the stroke of the drive component and improving the efficiency of card issuing line retrieval, further contributing to energy saving. Through the coordinated action of the height adjustment component 3 and the drive component, the working efficiency of the card issuing line production line can be significantly improved.

[0037] In some embodiments, such as Figure 1 As shown, the height adjustment assembly 3 includes a fixing member 31 and at least one pad 32, with the at least one pad 32 located between the fixing member 31 and the frame 4. The fixing member 31 is used for detachably connecting the mounting plate 11 and the pad 32.

[0038] In this embodiment, by modularizing the height adjustment component 3, which includes a fixing member 31 and at least one pad 32, the height of the mounting plate 11 can be flexibly adjusted by replacing pads 32 of different specifications or changing the number of pads 32, thus reliably meeting the needs of joint operation under different working conditions. Simultaneously, the fixing member 31 detachably connects the mounting plate 11 and the pad 32. With the mounting plate 11 reliably fixed, the pad 32 can be flexibly detached and connected to the fixing member 31, further improving the efficiency of pad replacement and installation.

[0039] Specifically, such as Figure 2 As shown, the fastener 31 includes a first clamping part 311 and a second clamping part 312. The mounting plate 11 is clamped between the first clamping part 311 and the second clamping part, and the first clamping part 311, the second clamping part 312 and the mounting plate 11 are connected by a first fastener.

[0040] In this embodiment, by setting the first clamping part 311 and the second clamping part 312 to clamp the mounting plate 11 together, and connecting the three by the first fastener, a rigid fixing structure for the mounting plate 11 can be formed after fastening, which can effectively prevent the mounting plate 11 from displacing or vibrating when receiving external loads. At the same time, the detachable connection of the first fastener allows for quick release of clamping constraints. When changing the pad 32 to adjust the height, only the first fastener needs to be removed, without adjusting the other components, which can significantly improve maintenance efficiency and maintain the original positioning accuracy of the system.

[0041] In some embodiments, the first fastener may be a screw.

[0042] In some embodiments, such as Figure 1 , Figure 2 As shown, at least one pad 32 is located below the fixing member 31, and the first clamping part 311, the mounting plate 11, the second clamping part 312, the pad 32 and the frame 4 are connected by a second fastener.

[0043] In this embodiment, by placing at least one pad 32 below the fixing member 31, and connecting the first clamping part 311, mounting plate 11, second clamping part 312, pad 32, and frame 4 through a second fastener, the components can be integrated into one unit, effectively preventing relative displacement between parts. Simultaneously, the connection of the first clamping part 311, mounting plate 11, second clamping part 312, pad 32, and frame 4 through the second fastener also improves the stability of each component under impact. This connection method allows for quick replacement of the entire module by simply releasing the second fastener during disassembly, maintaining the integrity of the main structure of the buffer rack and the positioning accuracy during installation.

[0044] In some embodiments, such as Figure 1 , Figure 2 As shown, the first clamping part 311 includes a protrusion 3111 that protrudes along the height direction of the buffer rack, and the second clamping part 312 abuts against the top of the protrusion 3111. The first clamping part 311 and the second clamping part 312 form a clamping space for clamping the mounting plate 11.

[0045] In this embodiment, the second clamping part 312 abuts against the top of the protrusion 3111, and the two together form a clamping space to wrap the mounting plate 11. The surfaces of the protrusion 3111 and the second clamping part 312 that abut against each other can form a rigid support reference surface to prevent the second clamping part 312 from shifting when it is pressed. The wrapping constraint of the clamping space on the mounting plate 11 can effectively improve the torsional resistance of the mounting plate 11 and further improve the stability of the mounting plate 11 when it is fixed.

[0046] In some embodiments, such as Figure 2As shown, the second clamping part 312 has a positioning groove 3121, and the height adjustment assembly 3 also includes a positioning member (not shown in the figure). The positioning member includes a connecting part and a head. The connecting part is detachably connected to the mounting plate 11, and the head is embedded in the positioning groove 3121.

[0047] In this embodiment, by providing a positioning groove 3121 in the second clamping part 312 and making the connecting part of the positioning member detachably connected to the mounting plate 11, while the head of the positioning member is embedded in the positioning groove 3121, the connection reliability between the mounting plate 11 and the fixing member 31 is further improved. Simultaneously, the head embedded in the positioning groove 3121 can constrain the displacement of the mounting plate 11, preventing the second clamping part 312 from slipping relative to the mounting plate 11 under vibration conditions. The connecting part of the positioning member can be stably connected to the mounting plate 11. When the mounting plate 11 is connected to the second clamping part 312, the head cooperates with the positioning groove 3121 to achieve accurate positioning. Furthermore, during disassembly, it is only necessary to move the mounting plate 11 along the height direction to disengage the head from the positioning groove 3121, making disassembly convenient. Therefore, in this embodiment, by providing the positioning member and the positioning groove 3121, the disassembly and assembly efficiency of the mounting plate 11 can be significantly improved while maintaining positioning accuracy.

[0048] In such Figure 1 In the embodiment shown, the buffer rack may include two height adjustment components 3, and the two height adjustment components 3 are respectively located at both ends of the frame 4.

[0049] In some embodiments, the drive assembly includes a cylinder and a guide rail (not shown), the guide rail is mounted on the frame 4 and extends along a first direction, the cylinder is slidably mounted on the guide rail, a portion of the storage rack 12 is located above the mounting plate 11 and another portion is located below the mounting plate 11, and the cylinder is connected to the portion of the storage rack 12 located below the mounting plate 11.

[0050] In this embodiment, the two ends of the storage rack 12 can be located on both sides of the mounting plate 11, that is, the storage rack 12 can pass through the mounting plate 11, so that the mounting plate 11 can support at least part of the storage rack 12, ensuring that the storage rack 12 is stable and reliable. The guide rail is set on the frame 4 and extends along the first direction. The cylinder is slidably mounted on the guide rail, so that the cylinder can move along the guide rail in the first direction. The cylinder can drive the storage rack 12 at different positions along the first direction, which can improve the adaptability under different working conditions.

[0051] In some embodiments, such as Figure 1 As shown, a connecting rod and a connecting plate 121 are connected to the lower part of the storage rack 12. The mounting plate 11 has a through hole, and the connecting rod can move along the through hole. The end of the connecting plate 121 facing away from the connecting rod is used to connect with the cylinder.

[0052] In this embodiment, a connecting rod and a connecting plate 121 are provided below the storage rack 12, and the connecting rod moves along the through hole of the mounting plate 11. At the same time, the end of the connecting plate 121 away from the connecting rod can be connected to a cylinder. The cylinder pushes the connecting plate 121 and the connecting rod to move up and down along the through hole. The connection rod and the through hole cooperate to play a guiding role, so that the storage rack 12 can move along a predetermined movement path, preventing the storage rack 12 from tilting during the movement, and improving the stability and reliability of the storage rack 12.

[0053] In some embodiments, such as Figure 1 As shown, the buffer rack may also include an elastic element 2, which is sleeved on the connecting rod. One end of the elastic element 2 is connected to the connecting plate 121, and the other end is connected to the mounting plate 11 or the frame 4.

[0054] In this embodiment, the elastic element 2, sleeved on the connecting rod, is compressed under the pressure of the connecting plate 121 and the mounting plate 11 when the cylinder drives the connecting rod to move upward. When the cylinder stops working and resets, the elastic element 2's rebound force drives the connecting plate 121 to automatically reset the connecting rod, thereby automatically resetting the storage rack 12 under the drive of the connecting rod. Therefore, the storage rack 12 does not need to be driven to reset by other components, simplifying the structure of the buffer rack. Furthermore, during the process of the cylinder driving the connecting plate 121 towards the mounting plate 11, the elastic element 2 also acts as a buffer, reducing the impact during the cylinder's driving of the connecting plate 121. In addition, when the cylinder drives the other storage racks 12, there is no interference between different storage racks 12, affecting the retrieval of the card issuing wire, further improving the stability of the buffer rack's operation.

[0055] The above descriptions are merely specific implementations of the embodiments of this application, but the protection scope of the embodiments of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the embodiments of this application should be covered within the protection scope of the embodiments of this application. Therefore, the protection scope of the embodiments of this application should be determined by the protection scope of the claims.
