Description

Technical Field

[0001] This application relates to the field of computing device technology, and in particular to a needle straightening device. Background Technology

[0002] Blade servers are servers that can accommodate multiple card-type server units within a standard-height chassis, enabling high availability and high density.

[0003] As a critical component of blade servers, the backplane chassis contains connectors that serve as crucial hubs connecting compute nodes to the chassis. During R&D, production, testing, and maintenance, frequent plugging and unplugging of compute nodes can easily lead to pin reversal. However, because the backplane connectors are located inside the chassis, they are concealed, difficult to replace, and have limited operating space, making it extremely difficult to repair reversible pin reversal, and directly replacing the backplane would be extremely costly.

[0004] Therefore, how to solve the problem of the connector pins on the back panel of the chassis being difficult to repair after being reversed has become an urgent issue to be addressed. Summary of the Invention

[0005] This application provides a pin straightening device that can solve the problem of difficult repair after the connector pins on the back plate of the frame are reversed.

[0006] This application provides a pin straightening device for straightening connector pins inside a machine frame. The pin straightening device includes a fixed platform, an observation device, and a straightening mechanism. The fixed platform supports and fixes the connector pins inside the machine frame. The observation device is disposed on the fixed platform and is used to observe the connector pins. The straightening mechanism includes a connector, a straightening member, and a manipulator. The first end of the connector is movably connected to the fixed platform, and the second end of the connector is movably connected to the straightening member. The straightening member is used to connect to the connector pins. The first end of the manipulator is movably connected to the straightening member, and the second end of the manipulator is used to control the first end of the manipulator to move the straightening member and straighten the connector pins.

[0007] The pin straightening device provided in this application embodiment is used to straighten connector pins inside the machine frame. The pin straightening device includes a fixed platform, an observation device, and a straightening mechanism. By setting the fixed platform for support and fixation inside the machine frame, the stability and reliability of the pin straightening device when it extends into the machine frame to straighten the connector pins can be ensured. By placing the observation device on the fixed platform, the observation device is used to observe the connector pins, which not only facilitates observation of the connector pins through the observation device so that the pin straightening operation can be performed smoothly, but also ensures the stability and reliability of the observation device.

[0008] Meanwhile, by setting up a straightening mechanism including a connector, a straightening component, and an operating component, the first end of the connector is movably connected to the fixed platform, and the second end of the connector is movably connected to the straightening component; the straightening component is used to connect with the connector pins; and the first end of the operating component is movably connected to the straightening component, and the second end of the operating component is used to control the first end of the operating component to drive the straightening component to move and straighten the connector pins. This solves the problem of difficult repair after the connector pins on the back plate of the frame are bent, thus eliminating the need to replace the back plate of the frame and saving costs.

[0009] Optionally, the needle straightening device described above may further include a heating device, which includes a control body and a heating element. The control body is disposed on the fixed platform, and the heating element is disposed close to the straightening element. The control body is electrically connected to the heating element, and the control body is used to control the temperature of the heating element. The heating element is used to heat the straightening element.

[0010] The needle straightening device also includes a heating device, which consists of a control unit and a heating element. By setting the control unit on a fixed platform, it is not only beneficial to ensure the stability and reliability of the heating device installation, but also to ensure the integrity of the needle straightening device, making it convenient for the overall movement and application of the needle straightening device.

[0011] In addition, by placing the heating element close to the straightening element, the control body is electrically connected to the heating element, and the control body is used to control the temperature of the heating element. The heating element is used to heat the straightening element, so that when the straightening element straightens the connector pins, it can heat the connector pins, soften the connector pins and make them easier to straighten, thereby preventing the connector pins from breaking.

[0012] As described above, the needle straightening device may optionally include a connecting part and a sleeve part. The connecting part is disposed at the first end of the sleeve part, and the connecting part, the second end of the connecting part, and the first end of the operating part are rotatably connected. The second end of the sleeve part is used to sleeve the connector pin. The heating element is disposed at the connecting part and is used to heat a preset part of the sleeve part to a preset temperature through the connecting part.

[0013] By setting the straightening component to include a connecting part and a sleeve part, and placing the connecting part at the first end of the sleeve part, it is not only convenient to rotate the second end of the connecting component and the first end of the operating component to the connecting part at the first end of the sleeve part, but also to avoid the second end of the connecting component and the first end of the operating component interfering with the second end of the sleeve part for fitting the connector pins; thereby ensuring that the operation of controlling the second end of the sleeve part to fit and straighten the connector pins through the operating component can be carried out smoothly.

[0014] In addition, by providing a heating element at the connecting part, the heating element can heat a preset part of the sleeve to a preset temperature through the connecting part. When the connector pin is fitted onto the sleeve, the connector pin can be heated, making the connector pin soft and easy to straighten, so as to avoid the connector pin breaking.

[0015] In the needle straightening device described above, optionally, the preset part is located at the second end of the sleeve part, and the length of the preset part extending from the second end of the sleeve part toward the first end of the sleeve part is in the range of 2mm to 4mm; the preset temperature range is 60℃ to 80℃.

[0016] By setting a preset part at the second end of the sleeve, the preset part extends from the second end of the sleeve to the first end of the sleeve for a length of 2mm to 4mm, and the preset temperature ranges from 60℃ to 80℃, so that when the connector pin is fitted onto the second end of the sleeve, the preset part at the second end of the sleeve can better heat the connector pin, making the connector pin soft and easy to straighten, thereby preventing the connector pin from breaking.

[0017] In the above-described needle straightening device, optionally, the control body and the heating element are electrically connected via a flexible wire, the flexible wire extending along the connector and confined to the connector.

[0018] By setting the control body and the heating element to be electrically connected by a flexible wire, the flexible wire extends along the connector and is confined to the connector, which helps to limit the extension direction of the flexible wire. This not only avoids the flexible wire extending messily and interfering with the use of the needle straightening device, or pulling on the components in the machine frame, but also ensures the reliability of the connection between the control body and the heating element.

[0019] Optionally, the needle straightening device described above may further include a lighting device disposed on the fixed platform, the lighting device being used to illuminate the interior of the machine frame.

[0020] The pin straightening device also includes a lighting device, which is set on a fixed platform and used to illuminate the inside of the frame. This not only facilitates the observation of the connector pins so that the pin straightening operation can be carried out smoothly, but also helps to ensure the stability and reliability of the lighting device installation, ensures the integrity of the pin straightening device, and facilitates the overall movement and application of the pin straightening device.

[0021] As described above, the needle straightening device may optionally include a mounting platform and two telescopic mechanisms; the two telescopic mechanisms are arranged at intervals along a first direction and are located on opposite sides of the mounting part, and the ends of the two telescopic mechanisms opposite to the mounting part extend and retract along the first direction, and are used to abut or disengage from the two opposite inner walls inside the machine frame; the observation device is disposed on the mounting part; and the first end of the connector is movably connected to the mounting part.

[0022] By setting two telescopic mechanisms spaced apart along a first direction and positioned on opposite sides of the mounting portion, the ends of both mechanisms facing away from the mounting portion extend and retract along the first direction, allowing them to abut or disengage from the two opposite inner walls of the machine frame. This allows the needle straightening device to be fixed between the two opposite inner walls of the machine frame during the needle straightening operation by raising the telescopic mechanisms; or, after the needle straightening operation is completed, the needle straightening device can be easily removed from the machine frame by lowering the telescopic mechanisms. Furthermore, lowering the telescopic mechanisms reduces the size of the needle straightening device, facilitating its storage.

[0023] Furthermore, by mounting the observation device on the mounting section, the stability and reliability of the observation device are ensured. By movably connecting the first end of the connector to the mounting section, the first end of the connector can move relative to the mounting section, thereby ensuring the flexibility of the connector in driving the straightening member.

[0024] In the needle straightening device described above, the dimension of the fixing platform along the first direction can optionally range from 10mm to 40mm.

[0025] By setting the size range of the fixed platform along the first direction from 10mm to 40mm, the fixed platform can be applied to machine frames of different heights, thereby expanding the applicability of the needle straightening device.

[0026] In the above-described needle straightening device, optionally, the first end of the connector is movably connected to the mounting part via a rotating connector; the rotating connector includes a rotating connecting part and a locking part, the first end of the rotating connecting part is rotatably connected to the first end of the connector, and the second end of the rotating connecting part is rotatably connected to the mounting part; the locking part is disposed on the rotating connecting part, and the locking part is used to lock or release the first end of the connector and the mounting part.

[0027] By setting the first end of the connector to be movably connected to the mounting part through a rotating connector, and by setting the rotating connector to include a rotating connecting part and a locking part, the two ends of the rotating connecting part are respectively rotatably connected to the connector and the mounting part, and the locking part is used to lock or loosen the rotating connecting part to control the connection relationship and relative movement between the connector and the mounting part. This not only facilitates the adjustment of the flexibility of the first end of the connector relative to the mounting part, but also allows the first end of the connector to be locked relative to the mounting part for storage.

[0028] As described above, the pin straightening device may optionally include a support foot on the fixing platform, which is used to abut against the side of the connector pin and the fixing platform.

[0029] By providing support feet on the fixed platform and having the support feet abut against the side where the connector pins are located and between the fixed platform, a limit is formed between the side where the connector pins are located and the fixed platform. This not only prevents the fixed platform from squeezing the connector pins, but also leaves sufficient operating space for the straightening mechanism.

[0030] Optionally, in the above-described needle straightening device, the observation device includes a telescope, one end of the telescope near the objective lens is connected to the fixed platform, and the other end of the telescope near the eyepiece is retractable relative to the fixed platform.

[0031] By setting up an observation device including a telescope, with one end of the telescope near the objective lens connected to a fixed platform, and the other end of the telescope near the eyepiece retractable relative to the fixed platform, on the one hand, when the fixed platform extends deep into the frame, the end of the telescope near the eyepiece can be extended out of the frame so that the connector pins can be observed through the telescope; on the other hand, when the second end of the telescope is retracted, the volume of the pin straightening device can be reduced, making it easier to store.

[0047] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0048] Printed circuit boards (PCBs), also known as circuit boards or printed circuit boards, provide electrical connections for passive electronic devices. With the rapid development of electronic technology, PCBs are widely used in various fields, and almost all electronic devices contain corresponding PCBs. The main advantages of using PCBs are significantly reduced wiring and assembly errors, improved automation levels, and increased production efficiency.

[0049] In related technologies, the solution to the connector pin-down problem on the chassis backplate is primarily preventative, reducing the occurrence of pin-down by fixing the connector to the mounting plate. If pin-down does occur, the chassis needs to be returned to the factory, the backplate removed, and the pin-down repaired and restored. However, this method of repairing connector pin-down on the chassis backplate is not only complex and cumbersome but also extremely costly.

[0050] In view of this, this application provides a pin straightening device for straightening connector pins inside a machine frame. The pin straightening device includes a fixed platform, an observation device, and a straightening mechanism. By providing a fixed platform for support and fixation inside the machine frame, the stability and reliability of the pin straightening device when it extends into the machine frame to straighten the connector pins can be ensured. By placing the observation device on the fixed platform, the observation device is used to observe the connector pins, which not only facilitates observation of the connector pins through the observation device so that the pin straightening operation can be performed smoothly, but also ensures the stability and reliability of the observation device.

[0051] Meanwhile, by setting up a straightening mechanism including a connector, a straightening component, and an operating component, the first end of the connector is movably connected to the fixed platform, and the second end of the connector is movably connected to the straightening component; the straightening component is used to connect with the connector pins; and the first end of the operating component is movably connected to the straightening component, and the second end of the operating component is used to control the first end of the operating component to drive the straightening component to move and straighten the connector pins. This solves the problem of difficult repair after the connector pins on the back plate of the frame are bent, thus eliminating the need to replace the back plate of the frame and saving costs.

[0052] To make the objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions for the computer and computer clusters provided by the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Furthermore, all other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] Figure 1 A schematic diagram of the structure of the needle straightening device 100 provided in an embodiment of this application, which extends into the machine frame 200; Figure 2 for Figure 1 Enlarged diagram of point A in the middle.

[0054] Reference Figure 1 and Figure 2 As shown, the chassis 200 in this embodiment includes, but is not limited to, a blade server chassis 200, and may also be other chassis 200 with a similar structure to the blade server chassis 200. This embodiment uses a blade server chassis 200 as an example for illustration.

[0055] The chassis 200 is typically a cuboid structure with six faces: a front and rear side arranged at intervals along the X direction, a left and right side arranged along the Y direction, and a bottom and top side arranged along the Z direction. The bottom, top, left, right, and rear faces can be solid wall structures; that is, the bottom face has a bottom wall, the top face has a top wall, the left face has a left side wall (not shown), the right face has a right side wall, and the rear face has a rear wall 210, so that the bottom, top, left, right, and rear walls 210 together form the chassis. The front face may not have a solid wall structure, leaving it open as a mounting opening.

[0056] The back panel of the frame 200 can be provided on the side of the rear wall 210 facing the front. For example, the back panel of the frame 200 can be a printed circuit board, which can be fixed to the side of the rear wall 210 facing the front by screws or other fasteners; or, the back panel of the frame 200 can be a cable back panel, which can be fixed to the rear wall 210 by cable ties, cable clips, etc.

[0057] The back panel of the chassis 200 can be provided with connectors 220. For example, when the back panel of the chassis 200 is a printed circuit board, the connectors 220 can be electrically connected to the back panel of the chassis 200 by soldering; or, when the back panel of the chassis 200 is a cable back panel, the connectors 220 can be electrically connected to the cable back panel by soldering or wire crimping.

[0058] The blade server can be inserted into the chassis 200 along the X direction through the mounting port on the front side and connected to the connector 220 on the back panel of the chassis 200; or, the blade server can be removed from the chassis 200 through the mounting port on the front side.

[0059] When the pins of the connector 220 on the back panel of the chassis 200 become misaligned or tilted during repeated insertion and removal of the blade server, the pin straightening device 100 of this embodiment can extend into the chassis 200 along the X direction through the mounting port on the front side in order to straighten the pins of the connector 220 on the back panel of the chassis 200.

[0060] The needle straightening device 100 of this application embodiment may include: a fixed platform 110, an observation device 120, and a straightening mechanism 130.

[0061] The fixing platform 110 is used to support and fix the device inside the machine frame 200. For example, the fixing platform 110 can be configured as a telescopic structure along the Z-direction. Before the needle straightening device 100 extends into the machine frame 200, the fixing platform 110 can retract along the Z-direction to reduce the height of the needle straightening device 100 in the Z-direction, thereby facilitating not only the insertion of the needle straightening device 100 into the machine frame 200 but also its retraction. After the needle straightening device 100 extends into the machine frame 200, the fixing platform 110 can extend along the Z-direction so that both ends of the fixing platform 110 along the Z-direction can respectively abut against the top and bottom walls of the machine frame 200 (see [link]). Figure 1 This allows the needle straightening device 100 to be fixed inside the machine frame 200, ensuring the stability of the needle straightening device 100.

[0062] An observation device 120 is mounted on a fixed platform 110 and is used to observe connector pins 221. The observation device 120 may include a telescope, with one end of the telescope near the objective lens connected to the fixed platform 110, and the other end of the telescope near the eyepiece retractable relative to the fixed platform 110. For example, when the pin alignment device 100 is located inside the frame 200, the end of the telescope near the objective lens can be connected to the side of the fixed platform 110 opposite to the connector 220, and a first clearance hole 1111 may be provided on the fixed platform 110 (see [link to documentation]). Figure 6 The end of the telescope near the objective lens can be aligned with the connector 220 on the back plate of the frame 200 via the first clearance hole 1111. The end of the telescope near the eyepiece can extend through the mounting port on the front side of the frame 200 so as to observe the connector 220 on the back plate of the frame 200 through the end of the telescope near the eyepiece.

[0063] The straightening mechanism 130 includes a connector 131, a straightening member 132, and an operating member 133. The first end of the connector 131 is movably connected to the fixed platform 110; exemplarily, the first end of the connector 131 and the fixed platform 110 can be movably connected via a rotating connector 134. The second end of the connector 131 is movably connected to the straightening member 132; exemplarily, the second end of the connector 131 and the straightening member 132 can be rotatably connected via a rotating shaft connector 135. The straightening member 132 is used to connect to a connector pin 221; exemplarily, the straightening member 132 may have a sleeve portion 1321, which can be sleeved onto the connector pin 221 to achieve the connection between the straightening member 132 and the connector pin 221. The first end of the operating member 133 is movably connected to the straightening member 132; exemplarily, the first end of the operating member 133 and the straightening member 132 can be rotatably connected via a rotating shaft connector 135. The second end of the operating member 133 is used to control the first end of the operating member 133 to drive the straightening member 132 to move and straighten the connector pin 221.

[0064] In application, when the needle straightening device 100 is located inside the frame 200, the second end of the operating member 133 can extend through the mounting port on the front side of the frame 200, so that the operator can hold the second end of the operating member 133 and control the operating member 133. First, the first end of the operating member 133 drives the straightening member 132 to connect with the misaligned or tilted connector pin 221. Then, the first end of the operating member 133 drives the straightening member 132 to straighten the misaligned or tilted connector pin 221. Finally, the first end of the operating member 133 drives the straightening member 132 to disengage from the connector pin 221, so that the needle straightening device 100 can be removed from inside the frame 200.

[0065] In one possible implementation, the needle straightening device 100 may further include an illumination device 140, which is disposed on the fixed platform 110 and is used to illuminate the interior of the machine frame 200. Exemplary examples include, but are not limited to, flashlights and laser lights.

[0066] When the needle alignment device 100 is located inside the frame 200, the lighting device 140 can be positioned on the side of the fixed platform 110 facing the connector 220, so that the lighting device 140 can illuminate the connector 220 on the back plate of the frame 200. Alternatively, the lighting device 140 can be positioned on the side of the fixed platform 110 away from the connector 220. It is understood that the fixed platform 110 is provided with a second clearance hole 1112 (see...). Figure 6The light-emitting end of the lighting device 140 can be positioned opposite the back plate of the frame 200 via the second clearance hole 1112 to illuminate the connector 220 on the back plate of the frame 200. Alternatively, the lighting device 140 can be installed in the fixed platform 110 along the X direction. It is understood that the fixed platform 110 is provided with the second clearance hole 1112 (see...). Figure 6 The lighting device 140 can be inserted and fixed in the second clearance hole 1112, and the light-emitting end of the lighting device 140 is located at the end of the second clearance hole 1112 near the back plate of the frame 200, so as to illuminate the connector 220 on the back plate of the frame 200.

[0067] In one possible implementation, the fixed platform 110 may be provided with support feet (not shown) for abutting against the side where the connector pins 221 are located and the fixed platform 110. For example, when the pin straightening device 100 is located inside the frame 200, the first end of one of the opposite ends of the support foot may be connected to the side of the fixed platform 110 facing the back plate of the frame 200, and the second end of the opposite ends of the support foot may abut against the back plate of the frame 200 or the rear wall 210 of the frame 200, so as to maintain a distance between the fixed platform 110 and the back plate of the frame 200, preventing the fixed platform 110 from getting too close to or pressing against the connector 220 on the back plate of the frame 200, thus affecting the operation of the pin straightening device 100 in straightening the connector pins 221.

[0068] The number of support legs can be three. The first ends of the three support legs can be spaced apart on the fixed platform 110 and arranged to form the three vertices of a triangle. The second ends of the three support legs can abut against the back plate or rear wall 210 of the frame 200 at intervals and arranged to form the three vertices of a triangle, thereby helping to ensure the stability of the support legs between the back plate of the frame 200 and the fixed platform 110. Alternatively, the number of support legs can be four, with the first and second ends of the four support legs spaced apart to form the four vertices of a quadrilateral; or the number of support legs can be one, two, or other numbers, as long as the requirements of this embodiment are met, which will not be elaborated here.

[0069] Figure 3 This is a schematic diagram of the structure of a needle straightening device 100 provided in an embodiment of this application.

[0070] Reference Figure 3 As shown, the needle straightening device 100 of this application embodiment may include a fixed platform 110, an observation device 120 and a straightening mechanism 130.

[0071] The fixing platform 110 is used to support and fix the device inside the frame 200. For example, the fixing platform 110 can be configured along the Z direction (see...). Figure 1The structure is retractable. Before the needle straightening device 100 extends into the machine frame 200, the fixing platform 110 can retract along the Z direction to reduce the height of the needle straightening device 100 in the Z direction, thus facilitating not only the insertion of the needle straightening device 100 into the machine frame 200 but also its storage. After the needle straightening device 100 extends into the machine frame 200, the fixing platform 110 can extend along the Z direction so that both ends of the fixing platform 110 in the Z direction can respectively abut against the top and bottom walls of the machine frame 200 (see...). Figure 1 This allows the needle straightening device 100 to be fixed inside the machine frame 200, ensuring the stability of the needle straightening device 100.

[0072] An observation device 120 is mounted on a fixed platform 110 and is used to observe connector pins 221. The observation device 120 may include a telescope, with one end of the telescope near the objective lens connected to the fixed platform 110, and the other end of the telescope near the eyepiece retractable relative to the fixed platform 110. For example, when the pin alignment device 100 is located inside the frame 200, the end of the telescope near the objective lens can be connected to the side of the fixed platform 110 opposite to the connector 220, and a first clearance hole 1111 may be provided on the fixed platform 110 (see [link to documentation]). Figure 6 The end of the telescope near the objective lens can be aligned with the connector 220 on the back plate of the frame 200 via the first clearance hole 1111. The end of the telescope near the eyepiece can extend through the mounting port on the front side of the frame 200 so as to observe the connector 220 on the back plate of the frame 200 through the end of the telescope near the eyepiece.

[0073] The straightening mechanism 130 includes a connector 131, a straightening member 132, and an operating member 133. The first end of the connector 131 is movably connected to the fixed platform 110; exemplarily, the first end of the connector 131 and the fixed platform 110 can be movably connected via a rotating connector 134. The second end of the connector 131 is movably connected to the straightening member 132; exemplarily, the second end of the connector 131 and the straightening member 132 can be rotatably connected via a rotating shaft connector 135. The straightening member 132 is used to connect to a connector pin 221; exemplarily, the straightening member 132 may have a sleeve portion 1321, which can be sleeved onto the connector pin 221 to achieve the connection between the straightening member 132 and the connector pin 221. The first end of the operating member 133 is movably connected to the straightening member 132; exemplarily, the first end of the operating member 133 and the straightening member 132 can be rotatably connected via a rotating shaft connector 135. The second end of the operating member 133 is used to control the first end of the operating member 133 to drive the straightening member 132 to move so as to straighten the connector pin 221.

[0074] In one possible implementation, the needle straightening device 100 may further include an illumination device 140, which is disposed on the fixed platform 110 and is used to illuminate the interior of the machine frame 200. Exemplary examples include, but are not limited to, flashlights and laser lights.

[0075] When the needle alignment device 100 is located inside the frame 200, the lighting device 140 can be positioned on the side of the fixed platform 110 facing the connector 220, so that the lighting device 140 can illuminate the connector 220 on the back plate of the frame 200. Alternatively, the lighting device 140 can be positioned on the side of the fixed platform 110 away from the connector 220. It is understood that the fixed platform 110 is provided with a second clearance hole 1112 (see...). Figure 6 The light-emitting end of the lighting device 140 can be positioned opposite the back panel of the chassis 200 via the second clearance hole 1112 to illuminate the connector 220 on the back panel of the chassis 200. Alternatively, the lighting device 140 can be positioned along the X direction (see...). Figure 1 It is understood that the fixed platform 110 is provided with a second clearance hole 1112 (see...) Figure 6 The lighting device 140 can be inserted and fixed in the second clearance hole 1112, and the light-emitting end of the lighting device 140 is located at the end of the second clearance hole 1112 near the back plate of the frame 200, so as to illuminate the connector 220 on the back plate of the frame 200.

[0076] In one possible implementation, the needle straightening device 100 may further include a heating device (not shown), which includes a control body and a heating element. The control body is disposed on the fixed platform 110, and exemplaryly, the control body may be mounted on the fixed platform 110 by fasteners such as screws. The heating element is disposed near the straightening member 132, and exemplaryly, the heating element may be disposed on the straightening member 132, or the heating element may be disposed at one end of the connector 131 near the straightening member 132.

[0077] The control unit is electrically connected to the heating element. The control unit controls the temperature of the heating element, which in turn heats the straightening element 132, allowing the straightening element 132 to heat the connector pins 221, softening them and making them easier to straighten. For example, the heating element can be a heating wire. The control unit may include a circuit and a control knob. The heating wire can be connected in series or parallel in the circuit structure. The knob can control the current flowing through the heating wire via the circuit, thereby controlling the temperature of the heating wire.

[0078] In one possible implementation, the control unit and the heating element can be electrically connected via a flexible wire that extends along the connector 131 and is confined to the connector 131. For example, the flexible wire can be wound around the connector 131, or it can be secured to the connector 131 with cable ties or wire clips, thereby preventing the flexible wire from interfering with the operation of the straightening mechanism 130.

[0079] In one possible implementation, the needle straightening device 100 may further include a battery pack (not shown) disposed on the fixed platform 110. The battery pack may be electrically connected to the heating device and the lighting device 140 to supply power to the heating device and the lighting device 140. Exemplarily, the voltage of the battery pack may be from 5V to 12V.

[0080] In one possible implementation, the fixed platform 110 may be provided with support feet (not shown) for abutting against the side where the connector pins 221 are located and the fixed platform 110. For example, when the pin straightening device 100 is located inside the frame 200, the first end of one of the opposite ends of the support foot may be connected to the side of the fixed platform 110 facing the back plate of the frame 200, and the second end of the opposite ends of the support foot may abut against the back plate of the frame 200 or the rear wall 210 of the frame 200, so as to maintain a distance between the fixed platform 110 and the back plate of the frame 200, preventing the fixed platform 110 from getting too close to or pressing against the connector 220 on the back plate of the frame 200, thus affecting the operation of the pin straightening device 100 in straightening the connector pins 221.

[0081] The number of support legs can be three. The first ends of the three support legs can be spaced apart on the fixed platform 110 and arranged to form the three vertices of a triangle. The second ends of the three support legs can abut against the back plate or rear wall 210 of the frame 200 at intervals and arranged to form the three vertices of a triangle, thereby helping to ensure the stability of the support legs between the back plate of the frame 200 and the fixed platform 110. Alternatively, the number of support legs can be four, with the first and second ends of the four support legs spaced apart to form the four vertices of a quadrilateral; or the number of support legs can be one, two, or other numbers, as long as the requirements of this embodiment are met, which will not be elaborated here.

[0082] Figure 4 This is a schematic diagram of the straightening mechanism 130 of the needle straightening device 100 provided in an embodiment of this application;

[0083] Reference Figure 4As shown, the straightening mechanism 130 of this application embodiment includes a connector 131, a straightening member 132, and an operating member 133. The first end of the connector 131 is movably connected to the fixed platform 110. For example, the first end of the connector 131 and the fixed platform 110 can be movably connected via a rotating connector 134. The rotating connector 134 includes a rotating connecting portion 1342 and a locking portion 1341. The first end of the rotating connecting portion 1342 is rotatably connected to the first end of the connector 131, and the second end of the rotating connecting portion 1342 is rotatably connected to the mounting portion 111. The locking portion 1341 is disposed on the rotating connecting portion 1342 and is used to lock or release the first end of the connector 131 and the mounting portion 111.

[0084] For example, a first connecting ball head 1311 may be provided at the first end of the connector 131, and a second connecting ball head 1113 may be provided on the side of the mounting portion 111 (see...). Figure 6 The rotating connection portion 1342 includes two rotating connection sub-parts arranged opposite to each other and spaced apart. A first ball joint 1343 is provided at the first end of each of the two rotating connection sub-parts, and a second ball joint 1344 is provided at the second end of each of the two rotating connection sub-parts. A first connecting ball 1311 is rotatably connected to the first ball joint 1343, and a second connecting ball 1113 is rotatably connected to the second ball joint 1344. A locking portion 1341 is threaded between the first and second ends of the two rotating connection sub-parts. Rotation of the locking portion 1341 can bring the two rotating connection sub-parts closer together and clamp the first connecting ball 1311 and the second connecting ball 1113, or rotation of the locking portion 1341 can move the two rotating connection sub-parts further apart and release the first connecting ball 1311 and the second connecting ball 1113, thereby adjusting the flexibility of movement of the first end of the connector 131 relative to the mounting portion 111.

[0085] The second end of the connector 131 is movably connected to the straightener 132. Exemplarily, the second end of the connector 131 and the straightener 132 can be rotatably connected via a rotating shaft connector 135. The straightener 132 is used to connect to the connector pin 221. Exemplarily, the straightener 132 may have a sleeve portion 1321, which can be sleeved onto the connector pin 221 to achieve the connection between the straightener 132 and the connector pin 221. The first end of the operating member 133 is movably connected to the straightener 132. Exemplarily, the first end of the operating member 133 and the straightener 132 can be rotatably connected via a rotating shaft connector 135. The second end of the operating member 133 is used to control the first end of the operating member 133 to drive the straightener 132 to move and straighten the connector pin 221.

[0086] In one possible implementation, the second end of the connector 131, the first end of the operating member 133, and the straightening member 132 can be rotatably connected via the same pivot connector 135. The second end of the connector 131 can be located between the first end of the operating member 133 and the straightening member 132; or, the first end of the operating member 133 can be located between the second end of the connector 131 and the straightening member 132; or, the straightening member 132 can be located between the first end of the operating member 133 and the second end of the connector 131. The straightening member 132 can rotate 90 degrees left and right relative to the connector 131, totaling 180 degrees, and the operating member 133 can rotate 90 degrees left and right relative to the straightening member 132, totaling 180 degrees. For example, a stop step 1323 can be provided at the end of the straightening member 132 near the connector 131 (see...). Figure 5 So that the limiting and straightening component 132 can rotate 90 degrees to the left and right relative to the connecting component 131, and the limiting and operating component 133 can rotate 90 degrees to the left and right relative to the straightening component 132.

[0087] Figure 5 A schematic diagram of the straightening member 132 of the anti-needle straightening device 100 provided in an embodiment of this application;

[0088] Reference Figure 5 As shown, the straightening member 132 in this embodiment includes a connecting portion 1322 and a sleeve portion 1321. The connecting portion 1322 is disposed at the first end of the sleeve portion 1321. The connecting portion 1322, the second end of the connecting member 131, and the first end of the operating member 133 are rotatably connected. For example, the connecting portion 1322 may be provided with a through hole, the second end of the connecting member 131 may be provided with a through hole, and the first end of the operating member 133 may be provided with a through hole. The three through holes are aligned with each other. The rotating shaft connecting member 135 passes through the three through holes and can rotate in the three through holes. Nuts may be installed at both ends of the rotating connecting shaft, or rivet heads may be provided at both ends of the rotating connecting shaft to prevent the connecting portion 1322, the second end of the connecting member 131, and the first end of the operating member 133 from dislodging from the rotating shaft connecting member 135. The second end of the connector 131 may be located between the first end of the operating member 133 and the connecting portion 1322 of the straightening member 132; or, the first end of the operating member 133 may be located between the second end of the connector 131 and the connecting portion 1322 of the straightening member 132; or, the connecting portion 1322 of the straightening member 132 may be located between the first end of the operating member 133 and the second end of the connector 131.

[0089] The straightening member 132 can rotate 90 degrees left and right relative to the connecting member 131, for a total of 180 degrees. The operating member 133 can rotate 90 degrees left and right relative to the straightening member 132, for a total of 180 degrees. For example, a stop step 1323 can be provided on one side of the connecting portion 1322 of the straightening member 132, and the second end of the connecting member 131 and the first end of the operating member 133 are respectively connected to the stop steps 1323 on both sides of the connecting portion 1322; or, a stop step 1323 can be provided on one side of the connecting portion 1322 of the straightening member 132, and the second end of the connecting member 131 and the first end of the operating member 133 can be stacked and connected to the stop step 1323, so as to limit the straightening member 132 from rotating 90 degrees left and right relative to the connecting member 131 and limit the operating member 133 from rotating 90 degrees left and right relative to the straightening member 132.

[0090] The second end of the sleeve portion 1321 is used to accommodate connector pins 221. The length of the connector pins 221 is typically 30mm to 45mm, and the spacing between two adjacent connector pins 221 is typically 20mm. The outer diameter of the sleeve portion 1321 is typically 8mm to 15mm. For example, the outer diameter of the sleeve portion 1321 can be set to any value between 8mm, 10mm, 12mm, 14mm, 15mm, or 8mm to 15mm, depending on actual needs. The inner diameter of the sleeve portion 1321 is typically 3mm to 8mm. For example, the inner diameter of the sleeve portion 1321 can be set to any value between 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, or 3mm to 8mm, depending on actual needs. It is understood that the outer diameter of the sleeve portion 1321 is larger than the inner diameter of the sleeve portion 1321, and the sidewall thickness of the sleeve portion 1321 can be 1mm or more. The length of the sleeve portion 1321 can be greater than the length of the connector pin 221, or the length of the sleeve portion 1321 can be equal to the length of the connector pin 221.

[0091] When the needle straightening device 100 includes a heating device, the heating element of the heating device can be disposed on the connecting portion 1322 of the straightening member 132. For example, the heating element can be a heating wire wound around the connecting portion 1322 of the straightening member 132, or the heating element can be a heating plate attached to the connecting portion 1322. The heating element is used to heat a predetermined portion of the sleeve portion 1321 to a predetermined temperature via the connecting portion 1322.

[0092] In one possible implementation, the preset portion can be located at the second end of the sleeve portion 1321, and the length of the preset portion extending from the second end of the sleeve portion 1321 towards the first end of the sleeve portion 1321 ranges from 2 mm to 4 mm. The preset temperature ranges from 60°C to 80°C. For example, the length of the preset portion extending from the second end of the sleeve portion 1321 towards the first end of the sleeve portion 1321 can be set to any value between 2 mm, 3 mm, 4 mm, or 2 mm to 4 mm, depending on actual needs. The preset temperature can be set to any value between 60°C, 65°C, 70°C, 75°C, 80°C, or 60°C to 80°C, depending on actual needs.

[0093] The bent portion of connector pin 221 is usually close to the root of connector pin 221. When sleeve portion 1321 is sleeved on connector pin 221, the preset portion of sleeve portion 1321 usually wraps around the bent portion of connector pin 221 so that the preset portion of sleeve portion 1321 can better heat the bent portion of connector pin 221, making connector pin 221 easier to straighten and less prone to breakage.

[0094] Figure 6 This is a schematic diagram of the fixed platform 110 of the needle straightening device 100 provided in an embodiment of this application.

[0095] Reference Figure 6 As shown, the fixed platform 110 of this embodiment includes a mounting portion 111 and two telescopic mechanisms 112. The two telescopic mechanisms 112 are arranged at intervals along a first direction and are respectively disposed on opposite sides of the mounting portion 111. The ends of the two telescopic mechanisms 112 facing away from the mounting portion 111 extend and retract along the first direction, and are used to abut or disengage from the two opposite inner walls inside the frame 200. When the needle straightening device 100 is located inside the frame 200, the first direction is the same as the Z direction, and the ends of the telescopic mechanisms 112 facing away from the mounting portion 111 can extend in a direction away from the mounting portion 111. The ends of the two telescopic mechanisms 112 facing away from the mounting portion 111 can abut against the inner side of the top wall and the inner side of the bottom wall of the frame 200 respectively (see...). Figure 1 For example, only one of the two telescopic mechanisms 112 may have one end of the telescopic mechanism 112 that is away from the mounting portion 111 extending in a direction away from the mounting portion 111; or, both ends of the telescopic mechanisms 112 that are away from the mounting portion 111 may extend in a direction away from the mounting portion 111, and the lengths of the extension of the two telescopic mechanisms 112 may be the same or different.

[0096] For example, the telescopic mechanism 112 may include a mechanism body 1121 and a control unit 1122. The telescopic direction of the mechanism body 1121 is the same as the first direction. The first end of the mechanism body 1121 along the telescopic direction can be connected to the side wall of the mounting part 111 along the first direction by means of welding, screw connection, etc. The second end of the mechanism body 1121 along the telescopic direction can extend and retract. The control unit 1122 may include a screw and a control end connected to one end of the screw. The screw is threadedly connected to the mechanism body 1121, and the control end is exposed outside the mechanism body 1121. Rotating the control end can control the extension and retraction of the mechanism body 1121. When the needle straightening device 100 is located inside the machine frame 200, the control end of the control unit 1122 faces the mounting port of the machine frame 200. A planar abutment 1123 can be provided at the end of the main body 1121 away from the installation part 111. The planar abutment 1123 has a relatively large contact area with the inner wall of the frame 200, and the pressure distribution is relatively uniform, thereby preventing the telescopic mechanism 112 from damaging the frame 200.

[0097] Optionally, the dimension of the fixed platform 110 along the first direction ranges from 10mm to 40mm. For example, when both telescopic mechanisms 112 of the fixed platform 110 are fully retracted, the dimension of the fixed platform 110 along the first direction can be 10mm; when both telescopic mechanisms 112 of the fixed platform 110 are fully extended, the dimension of the fixed platform 110 along the first direction can be 40mm. The dimension of the fixed platform 110 along the first direction can also be adjusted according to the height of the machine frame 200 along the Z direction so as to abut against the top and bottom walls of the machine frame 200 (see [reference]). Figure 1 For example, the dimension of the fixed platform 110 along the first direction can also be adjusted to any value between 15mm, 20mm, 25mm, 30mm, 35mm or 10mm to 40mm. When adjusting the dimension of the fixed platform 110 along the first direction, only one telescopic mechanism 112 can be adjusted, or both telescopic mechanisms 112 can be adjusted. The lengths of the two telescopic mechanisms 112 can be adjusted to be the same or different.

[0098] An observation device 120 is mounted on a mounting portion 111. For example, a first clearance hole 1111 and a second clearance hole 1112 may be provided on the mounting portion 111. The observation device 120 is connected to the first clearance hole 1111 of the mounting portion 111, and an illumination device 140 is connected to the second clearance hole 1112 of the mounting portion 111. This allows the observation device 120 to observe the connector 220 on the back panel of the frame 200 through the first clearance hole 1111, and allows the illumination device 140 to illuminate the connector 220 on the back panel of the frame 200 through the second clearance hole 1112.

[0099] The first end of the connector 131 is movably connected to the mounting portion 111. For example, a second connecting ball head 1113 is provided on the side of the mounting portion 111, which is used to rotatably connect with the second ball head mating portion 1344 of the rotating connector 134.
