[0004] However, the technical solution provided by the above-mentioned patent lacks the fixation of the lower mold, and the upper mold rotates to one side when the mold is opened, which can easily cause horizontal misalignment of the mold mating surface, causing the carbon fiber badminton racket to be subjected to asymmetrical shear force at the mold mating line position, thus creating a risk of tearing. Utility Model Content

[0005] Therefore, it is necessary to provide a mold opening unit for a carbon fiber badminton racket production line to address the risk of carbon fiber layer tearing caused by mold misalignment during the above-mentioned mold opening process.

[0006] This application provides a mold-opening unit for a carbon fiber badminton racket production line, including a frame, a fixing component, and a clamping component. The fixing component is connected to the frame. When the conveying unit of the production line drives the mold to the mold-opening station, the fixing component fixes the lower mold, and the clamping component clamps the upper mold and drives the upper mold away from the lower mold. The fixing component includes a top module disposed opposite to the lower mold and a first electric cylinder that drives the top module. Under the drive of the first electric cylinder, the top module abuts against the slot between the upper mold and the lower mold to fix the lower mold.

[0007] Optionally, it also includes a lifting assembly, which includes a base, a lifting cylinder, a lifting plate, and a support plate. The lifting cylinder is disposed on the base and connected to the lifting plate. A guide shaft is provided between the lifting plate and the base, and the lifting plate is slidably connected through the guide shaft. The support plate is disposed on the lifting plate for mounting the fixing assembly. There is a gap between the support plates to accommodate the conveying unit.

[0008] Optionally, the top modules are respectively disposed on both sides of the handle of the mold and at the head of the mold, forming a triangular structure. The top module disposed at the head of the mold and the top modules disposed on both sides of the handle face each other. A guide post is also provided between the top module and the first electric cylinder. One end of the guide post is fixedly connected to the top module, and the other end is slidably connected to the guide hole disposed on the side wall of the first electric cylinder.

[0009] Optionally, the fixing assembly further includes a fixing block disposed on one side of the pallet, the fixing block being adapted to the side shape of the lower mold, and the mold moving toward the fixing block under the drive of a first electric cylinder disposed on the other side of the pallet until the lower mold abuts against the fixing block.

[0010] Optionally, the top module has a wedge-shaped structure, and the thickness of one end of the top module facing the slot between the upper and lower molds is less than the thickness of the other end. Driven by the first electric cylinder, the top module is inserted into the slot between the upper and lower molds and drives the upper and lower molds to move away from each other.

[0011] Optionally, the gripping assembly includes a robotic arm, a clamping plate, and a second electric cylinder. The clamping plate is connected to the second electric cylinder and is mounted on the robotic arm. The clamping plate has protrusions that are adapted to the openings on the side of the upper mold. Under the drive of the second electric cylinder, a pair of clamping plates abut against the upper mold, and the protrusions engage with the openings on the side of the upper mold. The robotic arm is used to move the upper mold away from the lower mold.

[0012] Optionally, it also includes a positioning component for engaging the sliding base carrying the mold when the sliding base moves to the mold opening station. The positioning component includes a snap-fit ​​member disposed on the side of the conveying unit and a drive motor disposed on the bottom surface of the conveying unit base. The sliding base is provided with a snap-fit ​​groove adapted to the snap-fit ​​member. Under the drive of the drive motor, the snap-fit ​​member rotates to move closer to or away from the snap-fit ​​groove.

[0013] Optionally, the positioning assembly further includes a fixing member disposed on the side of the conveying unit, the fixing member having a through hole, the snap-fit ​​member passing through the through hole and rotating along the axis of the through hole.

[0014] Optionally, the snap-fit ​​component includes a rotating shaft passing through the through hole and snap fasteners disposed at both ends of the rotating shaft, wherein the spacing between the snap fasteners is equal to the spacing between adjacent sliding bases.

[0015] This application also provides a carbon fiber badminton racket production line assembly equipment, including a conveying unit and the aforementioned carbon fiber badminton racket production line mold opening unit.

[0016] Compared with the prior art, the technical solution provided in this application has the following advantages:

[0017] In the aforementioned carbon fiber badminton racket production line's mold-opening unit, the top module, driven by the first electric cylinder, inserts into the mold slot before mold opening. Through structural limiting, it firmly positions the lower mold on the worktable, providing strong support during the clamping of the upper mold and preventing displacement during opening. Simultaneously, the clamping assembly clamps and lifts the upper mold, ensuring it moves vertically during separation from the lower mold. This ensures the mating surfaces of the upper and lower molds remain aligned and flat during mold opening, effectively avoiding shearing forces caused by misalignment. This collaborative mechanism of "lower mold structural limiting + upper mold vertical lifting" not only solves the problem of mold misalignment caused by the lack of a fixed lower mold and the rotational opening of the upper mold, but also fundamentally eliminates the risk of shearing and tearing at the mold parting line in carbon fiber products by fixing the lower mold before separating the upper mold.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0034] See Figure 1An embodiment of this utility model provides a mold opening unit for a carbon fiber badminton racket production line, including a frame 100, a fixing component 200, and a clamping component 300. The fixing component 200 is connected to the frame 100. When the conveying unit 700 of the production line drives the mold to the mold opening station, the fixing component 200 fixes the lower mold, and the clamping component 300 clamps the upper mold and drives the upper mold away from the lower mold. The fixing component 200 includes a top module 210 arranged opposite to each other, and a first electric cylinder 220 that drives the top module 210. Under the drive of the first electric cylinder 220, the top module 210 abuts against the slot between the upper mold and the lower mold to fix the lower mold.

[0035] In this embodiment, the top module 210, driven by the first electric cylinder 220, is inserted into the slotted part of the mold before mold opening. Through structural limiting, the lower mold is firmly positioned on the worktable of the frame 100, providing strong support during the clamping of the upper mold and preventing displacement of the lower mold during opening. Simultaneously, the clamping assembly 300 clamps and lifts the upper mold, ensuring that the upper mold maintains vertical movement during separation from the lower mold. This ensures that the mating surfaces of the upper and lower molds remain aligned and flat during mold opening, effectively avoiding shearing forces caused by misalignment of the mating surfaces.

[0036] In summary, this embodiment, through the collaborative mechanism of "lower mold structure limiting + upper mold vertical lifting", not only solves the problem of mold misalignment caused by the lack of fixation of the lower mold and the rotation and opening of the upper mold, but also fundamentally eliminates the risk of shearing and tearing of carbon fiber products at the parting line by fixing the lower mold first and then separating the upper mold in a step-by-step operation mode.

[0037] See Figure 2 and Figure 3 In some embodiments, a lifting assembly 400 is also included. The lifting assembly 400 includes a base 410, a lifting cylinder 420, a lifting plate 430, and a support plate 440. The lifting cylinder 420 is disposed on the base 410 and connected to the lifting plate 430. A guide shaft 450 is provided between the lifting plate 430 and the base 410, and the two are slidably connected through the guide shaft 450. The support plate 440 is disposed on the lifting plate 430 and is used to install the fixing assembly 200. There is a gap between the support plates 440 to accommodate the conveying unit 700.

[0038] In this embodiment, the base 410, as the supporting main body, integrates a lifting cylinder 420 and a guide shaft 450 system. When the lifting cylinder 420 is activated, the lifting plate 430 smoothly rises and falls along the vertical direction defined by the guide shaft 450, eliminating horizontal displacement deviation. The support plate 440 is fixed to the upper surface of the lifting plate 430, and its spacing design always reserves passage space for the sliding base 600 of the annular conveying unit 700 during vertical lifting, ensuring that the mold conveying process is not interfered with by the lifting action. When the mold enters the mold opening station, the lifting plate 430 carries the support plate 440 to a preset height, so that the fixing component 200 installed on the support plate 440 forms reliable contact with the bottom surface of the lower mold and performs clamping. The rigid sliding cooperation between the guide shaft 450 and the lifting plate 430 ensures that the fixing component 200 carried by the support plate 440 always maintains a vertical alignment with the lower mold during the lifting process, avoiding local stress concentration caused by tilting. Through the coordinated design of mechanical transmission and space avoidance, the lifting mechanism achieves interference-free operation of the lower mold fixing action and the conveying path within a limited workstation space, enhancing the reliability of the mold opening process and the compactness of the equipment layout.

[0039] Furthermore, in this embodiment, the lifting cylinder 420 is positioned at the center of the base 410, i.e., on the central axis, while four guide shafts 450 are symmetrically distributed at the four corners of the lifting plate 430. Placing the lifting cylinder 420 on the central axis ensures that the lifting driving force acts directly on the center of gravity area of ​​the lifting plate 430, guaranteeing uniform transmission of the driving force and avoiding tilting or uneven force distribution of the lifting plate that may be caused by eccentric loading, thus promoting initial balance and smooth start-up during the lifting process. Simultaneously, positioning the guide shafts 450 at the four corners of the lifting plate 430 forms a guide support base with the maximum range. This layout greatly enhances the anti-overturning and anti-torsion capabilities of the lifting system. Even when the fixed component 200 applies a fixing force to the lower mold or there is slight dynamic disturbance, the four corner guides can strongly constrain the lifting plate 430, ensuring that it rises and falls precisely and stably according to the predetermined vertical trajectory. This further strengthens the elimination effect of horizontal displacement deviation and guarantees the absolute horizontal and vertical alignment accuracy of the pallet 440 and its fixed component 200. Therefore, the combination of the central setting of the lifting cylinder and the four-corner layout of the guide shaft not only optimizes the transmission and balance of force, but also greatly improves the smoothness, accuracy and reliability of the lifting assembly 400 by maximizing the guiding stability, providing a solid motion foundation for the stable and accurate fixing of the lower mold by the fixing assembly 200.

[0040] See Figures 2 to 4In some embodiments, the top module 210 is respectively disposed on both sides of the handle of the mold and at the head of the mold, forming a triangular structure. The top module 210 disposed at the head of the mold and the top modules 210 disposed on both sides of the handle face each other. A guide post 230 is also provided between the top module 210 and the first electric cylinder 220. One end of the guide post 230 is fixedly connected to the top module 210, and the other end is slidably connected to the guide hole disposed on the side wall of the first electric cylinder 220.

[0041] In this embodiment, the top modules 210 are respectively positioned on both sides of the handle and the head of the mold, forming a stable triangular structure. This effectively prevents any form of wobbling or rotation of the lower mold during the fixing process, providing more comprehensive and robust support and positioning compared to two-point or other linear layouts. Furthermore, this distribution takes into account the irregular shape of the badminton racket mold itself, ensuring effective fixing force is applied to the critical handle and head areas, resulting in a more uniform distribution of fixing force and reducing localized stress.

[0042] Secondly, the top module 210 set at the racket head and the top modules 210 set on both sides of the racket handle face each other, so that when the top modules 210 are driven, they can form a mechanical structure similar to clamps or braces, which can more effectively act on the characteristic parts such as the slots between the molds, generate stronger locking force or support force, and ensure that the lower mold is fixed very firmly and cannot be easily moved in the horizontal or vertical direction.

[0043] Finally, a guide post 230 is added between the top module 210 and the first electric cylinder 220. One end of the guide post 230 is fixedly connected to the top module 210, and the other end is slidably connected to a guide hole opened on the side wall of the first electric cylinder 220. This provides precise guidance for the movement of each top module 210, ensuring that the top module 210 moves strictly along a predetermined linear trajectory (perpendicular to the mold parting surface or parallel to the electric cylinder axis) under the drive of the first electric cylinder 220. This eliminates lateral sway or rotation during the movement, ensuring that the top module 210 can accurately and smoothly enter or abut the target slot position on the mold, avoiding jamming or misalignment. At the same time, the guide post 230 also shares the lateral force that the top module 210 may encounter, improving the rigidity and durability of the entire fixing assembly.

[0044] In this embodiment, when the lifting assembly 400 lifts the fixing assembly 200 to a preset height at the bottom of the lower mold, the first electric cylinder 220 drives a pair of top modules 210 to move towards each other in the horizontal direction, so that their front wedge-shaped structures are precisely engaged with the preset slots on the sidewall of the mold. The contact surface of the top module 210 forms a surface contact with the inner wall of the slot, locking the lateral displacement freedom of the lower mold through the dual action of friction and geometric constraints. This symmetrical clamping strategy ensures that the lower mold is subjected to balanced forces, avoiding mold deflection that may be caused by unilateral pressure.

[0045] See Figures 2 to 4 In some embodiments, the fixing component 200 further includes a fixing block 240 disposed on a support plate 440 on one side, the fixing block 240 being adapted to the side shape of the lower mold, and driven by a first electric cylinder 220 disposed on the support plate 440 on the other side, the mold moves toward the fixing block 240 until the lower mold abuts against the fixing block 240.

[0046] In this embodiment, when the lifting assembly 400 raises the support plate 440 to the bottom of the lower mold, the fixing block 240 mounted on one side of the support plate 440 forms a pre-positioning reference surface due to its shape adaptation to the side of the lower mold. The first electric cylinder 220 on the other side of the support plate 440 drives the lower mold to move horizontally toward the fixing block 240 until the side of the lower mold is completely in contact with the fixing block 240. This action achieves active alignment of the mold in the horizontal plane through motor drive, and eliminates the assembly gap between the mold and the fixing assembly 200 by utilizing the contoured contact surface of the fixing block 240. The fixing block 240 and the thrust of the motor drive side form a spatial constraint, effectively restricting the two degrees of freedom of the lower mold in the horizontal direction.

[0047] See Figures 2 to 4 In some embodiments, the top module 210 has a wedge-shaped structure, and the thickness of one end of the top module 210 facing the slot between the upper mold and the lower mold is less than the thickness of the other end. Under the drive of the first electric cylinder 220, the top module 210 is inserted into the slot between the upper mold and the lower mold and drives the upper mold and the lower mold to move away from each other.

[0048] In this embodiment, when the first electric cylinder 220 drives the wedge-shaped top module 210 to be horizontally inserted into the slot between the upper and lower molds, the thinner part of the front end of the top module 210 enters the slot gap first. As the top module 210 continues to advance, its gradually thickening wedge-shaped surface contacts the inner wall of the slot, converting the horizontal driving force into a vertical separation force. This mechanical conversion mechanism causes the upper and lower molds to produce a gradual displacement along the mold opening direction, avoiding the impact load caused by instantaneous separation.

[0049] See Figure 5 In some embodiments, the gripping assembly 300 includes a robotic arm 310, a clamping plate 320, and a second electric cylinder 330. The clamping plate 320 is connected to the second electric cylinder 330 and is mounted on the robotic arm 310. The clamping plate 320 has protrusions that are adapted to the openings on the side of the upper mold. Under the drive of the second electric cylinder 330, a pair of clamping plates 320 abut against the upper mold, and the protrusions engage with the openings on the side of the upper mold. The robotic arm 310 is used to move the upper mold away from the lower mold.

[0050] In this embodiment, when the second electric cylinder 330 drives a pair of clamping plates 320 to move centripetally, the protrusions on the surface of the clamping plates 320 form a geometric fit with the openings on the side of the upper mold. While clamping the mold, the protrusion-opening mating relationship achieves horizontal self-positioning. After the clamping plates 320 are locked, the robotic arm 310 smoothly lifts the upper and lower molds vertically, ensuring strict control over the separation path. The matching design of the protrusions and openings eliminates the positioning deviation caused by sliding of the contact surface in traditional planar clamping, effectively avoiding the risk of carbon fiber layer tearing due to mold misalignment in traditional synchronous mold opening.

[0051] See Figure 6 and Figure 7 In some embodiments, a positioning component 500 is also included, which is used to engage the sliding base 600 carrying the mold when the sliding base 600 moves to the mold opening station. The positioning component 500 includes a snap-fit ​​member 510 disposed on the side of the conveying unit 700 and a drive motor 520 disposed on the bottom surface of the base of the conveying unit 700. The sliding base 600 is provided with a snap-fit ​​groove adapted to the snap-fit ​​member 510. Under the drive of the drive motor 520, the snap-fit ​​member 510 rotates to move closer to or away from the snap-fit ​​groove.

[0052] In some embodiments, the positioning component 500 further includes a fixing member 530 disposed on the side of the conveying unit 700. The fixing member 530 has a through hole, and the snap-fit ​​member 510 passes through the through hole and rotates along the axis of the through hole.

[0053] In some embodiments, the snap-fit ​​member 510 includes a rotating shaft 511 with a through hole and snap fasteners 512 disposed at both ends of the rotating shaft 511, the spacing between the snap fasteners 512 being equal to the spacing between adjacent sliding bases 600.

[0054] Specifically, in this embodiment, the positioning component 500 of the conveying unit 700 achieves precise positioning of the sliding base 600 through a mechanical linkage design. When the sliding base 600, carrying the mold, moves along the annular slide rail to the mold closing or opening position, the drive motor 520 drives the rotating shaft 511 to rotate, causing the latch 512 to rotate around the through hole axis. At this time, the end of the latch 512 cuts into the locking groove on the side of the sliding base 600 at a preset angle, forming a mechanical lock, effectively suppressing the lateral movement of the sliding base 600 during the mold closing or opening stage. The through hole structure of the fixing member 530 provides a stable rotation fulcrum for the rotating shaft 511, and the matching design of the spacing between the latches 512 and the spacing between adjacent sliding bases 600 allows a single locking member 510 to simultaneously constrain the positioning state of multiple sliding bases 600.

[0055] The matching design of the spacing between the latches 512 of the positioning component 500 and the spacing between adjacent sliding bases 600 achieves synchronous locking at two workstations. When the sliding base 600 moves along the annular slide rail to the mold closing or opening station, the rotating shaft 511 of the latching component 510 rotates under the drive of the drive motor 520, causing the latches 512 on both sides to rotate synchronously. Since the spacing between the latches 512 is precisely equal to the interval between two adjacent sliding bases 600, the rotation of a single latching component 510 allows the latches 512 on both sides to be inserted into the latching grooves of the adjacent sliding bases 600, thereby simultaneously forming a lateral constraint on both sliding bases 600. This linkage locking mechanism achieves synchronous positioning at two workstations through a single drive element (drive motor 520), which reduces the number of drive units and ensures the timing consistency of the positioning actions of adjacent sliding bases 600 through mechanical linkage.

[0056] Furthermore, in this embodiment, the two side latches 512 of the positioning component 500 are simultaneously embedded into the locking grooves of the adjacent sliding base 600. The three-point mechanical constraint limits the lateral displacement of the sliding base 600 to within ±0.05mm, ensuring that the cavity axis remains strictly aligned when the upper and lower molds separate. This eliminates the asymmetrical separation force caused by mold misalignment in traditional equipment, allowing the carbon fiber layer to bear uniform peel stress during demolding and avoiding interlayer shear failure caused by stress concentration in local areas. At the same time, the wedge-shaped self-locking characteristics of the latches 512 and locking grooves can effectively counteract the interference of lateral force on mold positioning when the mold opening mechanism applies vertical separation force, maintaining the linearity of the mold separation trajectory and further ensuring smooth separation of the carbon fiber reinforcement layer from the mold surface. Compared with the gradual offset that is easily generated by traditional single-point positioning, this dual-station synchronous locking forces adjacent molds to maintain a preset distance and alignment relationship through mechanical linkage, ensuring that the initial alignment of the mold opening action is always within a controllable range, avoiding the risk of carbon fiber layer tearing caused by mold misalignment in traditional synchronous mold opening.

[0057] See Figure 7 and Figure 8 An embodiment of this utility model also provides a carbon fiber badminton racket production line assembly equipment, including a conveying unit 700 and the aforementioned carbon fiber badminton racket production line mold opening unit.

[0058] The technical features of the above embodiments can be combined in any way.
