Description

Technical Field

[0001] This invention belongs to the technical field of injection molding, and in particular relates to a protective ring manufacturing device and method. Background Technology

[0002] In the field of drones, especially small multi-rotor drones, protective rings are usually installed around the propeller blades to protect them, improve flight safety, and prevent harm to the surrounding environment or people. To improve the structural strength of the protective rings and resist impact deformation, lightweight, high-strength fiber rods (such as fiberglass rods, carbon fiber rods, etc.) are often used as a support frame and fixed to the inside of the protective rings or to a specific structure.

[0003] Currently, the mainstream process for fixing the fiber rod to the outer ring of the protective ring is manual dispensing. This involves an operator manually applying adhesive (such as epoxy resin or hot melt adhesive) to the predetermined contact points between the fiber rod and the outer ring of the protective ring using a handheld dispensing device. The connection and fixation are achieved after the adhesive cures.

[0004] However, this manual adhesive application method has significant drawbacks:

[0005] (1) Low processing efficiency: The operation process relies on manual dispensing of adhesive one by one. Each connection point needs to be operated separately and the adhesive needs to be allowed to cure. This makes it impossible to achieve continuous and batch production, which seriously restricts the overall production cycle and capacity of the protective ring assembly.

[0006] (2) Unstable yield: It is difficult to guarantee the consistency of manual operation, and problems such as misalignment of dispensing position, too much or too little glue, uneven glue coverage, glue leakage or overflow are very likely to occur. These factors directly lead to insufficient bonding strength, structural eccentricity, poor appearance, or even connection failure, resulting in poor quality stability of the final product, high defect rate, and increased rework and scrap costs.

[0007] Therefore, the manual dispensing method used in the existing technology for fixing the fiber rods of UAV propeller protective rings has become a key bottleneck restricting the improvement of production efficiency and product quality stability. There is an urgent need to develop a new fixing technology and equipment that is efficient, reliable and can ensure consistency. Summary of the Invention

[0066] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are some, but not all, of the embodiments of the present invention.

[0067] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0068] Example 1:

[0069] like Figures 1-7As shown, this embodiment presents a first embodiment of a protective ring manufacturing device, including a loading mechanism 10, a forming mechanism 20, and a transfer mechanism 30. The loading mechanism 10 includes a feeding assembly 110, a transmission assembly 120, a discharge tray 130, and two gripping assemblies. The transmission assembly 120 has the feeding assembly 110 and the discharge tray 130 respectively located at its two ends, and the gripping assemblies are arranged adjacent to both ends. The transmission assembly 120 is equipped with a mold core 40 for accommodating the fiber rod 50. The forming mechanism 20 has a mold groove and an injection cavity, forming a shell around the fiber rod 50 through injection molding. The transfer mechanism 30 includes lateral movement, lifting, and transfer components, responsible for transferring the mold core 40 between the loading and forming mechanisms 20.

[0070] In this embodiment, the mold core 40 refers to a movable carrier with a fiber rod 50 positioning structure, which can be implemented using a metal module with grooves. The shape of the grooves matches the cross-section of the fiber rod 50 to ensure precise positioning. The injection cavity refers to the molding space surrounding the mold core, which can be formed by the closing of upper and lower molds. The shape of this cavity is consistent with the outline of the protective ring shell. The lateral movement assembly refers to the horizontal movement device, which can be implemented using a combination of linear guide rails and servo motors to ensure precise positioning of the mold core between workstations. The lifting assembly refers to the vertical motion mechanism, which can be implemented using a cylinder-driven guide column structure, with sensors used for stroke control.

[0071] Specifically, after the fiber rod 50 is loaded onto the transfer assembly 120, the mold core 40 is gripped and transferred to the molding station by the transfer mechanism 30. The molding mechanism 20 forms a sealed injection cavity by closing the upper and lower molds, and the molten plastic is injected to encapsulate the fiber rod 50 to form an integral structure. The mold core 40 fixes the spatial position of the fiber rod 50 within the groove to ensure that the fiber rod 50 does not shift during the injection molding process. The transfer mechanism 30 realizes the circulation of the mold core between the loading station and the molding station through a combination of lateral and vertical movements. In the loading mechanism 10, the first gripping assembly 140 is responsible for transferring the fiber rod 50 from the feeding position to the mold core 40, and the second gripping assembly 150 transfers the finished product from the mold core 40 to the unloading tray 130.

[0072] Compared with existing technologies, this invention integrates the positioning of the fiber rod 50 and the shell forming process through the coordinated design of the mold core 40 and the injection mold. Traditional processes require separate steps for bonding the fiber rod 50 and forming the shell, while this device eliminates these intermediate steps through integrated molding. Existing technologies rely on manual adjustment of the fiber rod 50 position, while this device achieves automated positioning through the cooperation of the grooves in the mold core 40 and the gripping components. Traditional dispensing processes involve curing time; this solution achieves immediate fixation through injection molding, shortening the production cycle.

[0073] Through the above technical solutions, this invention achieves simultaneous molding of the fiber rod 50 and the protective ring shell, eliminating the manual dispensing process. An automated loading and transfer system ensures precise positioning of the fiber rod 50, avoiding human error. The mating design of the mold core 40 and the injection mold ensures the fiber rod 50 maintains a stable posture during molding. Continuous production significantly improves processing efficiency, while mechanical positioning enhances product consistency.

[0074] In some embodiments, the present invention proposes a feeding assembly 110 including a first support 111, a first cylinder 112, a feeding plate 113, and a first positioning sensor 115. The first support 111 is disposed adjacent to the transmission assembly 120, and the upper end of the first support 111 is disposed on a feeding platform, which is provided with a feeding groove. The first cylinder 112 is disposed at the lower end of the first support 111, and the feeding plate 113 is disposed at the driving end of the first cylinder 112. The upper end of the feeding plate 113 is provided with a plurality of placement slots 114, and the feeding plate 113 is raised and lowered along the feeding groove under the drive of the first cylinder 112. The first positioning sensor 115 detects the positioning of the fiber rod 50 in the placement slot 114 along the top of the stroke of the feeding plate 113.

[0075] In this embodiment, the feeding platform refers to a planar structure used to support the fiber rods 50 to be processed. Specifically, it can be formed from a metal plate or engineering plastic plate, and the feeding groove on its surface is used to guide the orderly arrangement of the fiber rods 50. The placement groove 114 refers to a recessed structure formed on the top of the loading plate 113. Specifically, it can be an equidistantly distributed U-shaped groove or V-shaped groove, used to temporarily fix the position of the fiber rods 50 during lifting. The first positioning sensor 115 refers to a detection device used to detect whether the fiber rods 50 have reached a predetermined height. Specifically, it can be a photoelectric sensor or a contact limit switch, determining whether the material is in place by detecting the position of the top of the fiber rods 50 within the placement groove 114.

[0076] Specifically, fiber rods 50 are placed in batches into the feeding trough of the feeding table, and the first cylinder 112 drives the loading plate 113 to reciprocate vertically. When the loading plate 113 rises to the top of its stroke, the placement trough 114 aligns with the feeding trough, and the fiber rods 50 roll into the placement trough 114 under gravity. Subsequently, the first positioning sensor 115 detects the position of the fiber rods 50 in the placement trough 114. After confirming that they are in position, the first cylinder 112 drives the loading plate 113 to descend to the receiving position of the transmission component 120. This lifting and lowering motion is synchronized with the stepping rhythm of the transmission component 120, realizing the continuous supply of fiber rods 50.

[0077] Compared with existing technologies, traditional manual feeding relies on operators to manually place the fiber bars 50, which suffers from large placement deviations and unstable feeding rhythms. This solution uses a cylinder-driven lifting mechanism in conjunction with a positioning sensor to achieve precise vertical positioning of the fiber bars 50, avoiding material offset or omissions caused by manual operation.

[0078] Through the above technical solution, the present invention achieves automatic alignment and positioning of the fiber rods 50 before transmission, ensuring the consistency of the position of the fiber rods 50 in each storage slot 114. This structure replaces manual handling with mechanized lifting motion, enabling the fiber rods 50 to enter the subsequent gripping process in a fixed posture, providing a precise material basis for subsequent automated assembly.

[0079] In some embodiments, the present invention proposes a transmission assembly 120 including a first slide rail 131 and a first slide block 132 disposed on the first slide rail 131. The upper end of the first slide block is provided with a loading slot 133 and a unloading slot 134 adjacent to each other. The mold core 40 is provided with a first groove 41. The loading slot 133 is provided with a first groove 135 for accommodating the mold core 40, and a support ring 136 is also provided on the periphery of the loading slot 133. The support ring 136 is provided with a support step 138, and the support step 138 is disposed on the same horizontal plane as the first groove 135. The unloading slot 134 is provided with a support step 138 for supporting the protective ring shell.

[0080] In this embodiment, the first slide rail 131 refers to the track structure used to support the first slide block and guide its sliding. Specifically, it can be implemented using a linear guide rail or a roller track. Its function is to provide a stable path for the horizontal movement of the mold core 40 and prevent deviation during transmission. The first slide block refers to the load-bearing component that moves along the first slide rail 131. Specifically, it can be implemented using a moving platform with sliders or rollers. Its function is to transport the mold core 40 from the loading slot 133 to the unloading slot 134 and ensure smooth movement. The loading slot 133 and the unloading slot 134 refer to the fixed positions used to place the unprocessed mold core 40 and the mold core 40 that has been injection molded, respectively. Specifically, they can be implemented using a slotted structure or a positioning fixture. Their function is to provide accurate initial and final positioning for the mold core 40. The support ring 136 refers to the annular structure surrounding the loading groove 133, which can be made of metal or plastic. Its support step 138 is coplanar with the first groove 135, and is used to provide horizontal support when the mold core 40 is placed, preventing the mold core 40 from tilting or sinking due to gravity. The support step 138 of the unloading groove 134 refers to the protruding structure set on the edge of the unloading groove 134, which can be implemented through a stepped design. Its function is to provide support after the protective ring shell is demolded, preventing the shell from deforming or falling off due to gravity.

[0081] Specifically, when the mold core 40 is placed in the first groove 135 of the loading slot 133, the support step 138 of the support ring 136 and the first groove 135 jointly support the mold core 40, ensuring its horizontal stability. The first slide moves along the first slide rail 131, transferring the mold core 40 from the loading slot 133 to the unloading slot 134. During this process, the first groove 41 is used to fix the fiber rod 50, preventing it from shifting during transfer. When the mold core 40 moves to the unloading slot 134, the support step 138 supports the protective ring shell, preventing the injection-molded shell from sagging due to gravity or sticking to the mold core 40. For example, the height of the support step 138 can be set to be flush with the bottom of the protective ring shell, so that separation can be achieved by simply lifting the mold core 40 vertically during demolding.

[0082] Compared with existing technologies, the positioning of the mold core 40 in traditional manual operation relies on manual adjustment by the operator, which is prone to human error, leading to displacement of the fiber rod 50 or insufficient support of the shell. This invention, however, achieves automatic transmission of the mold core 40 through the rigid fit between the first slide rail 131 and the slide block. Combined with the support ring 136 and the support step 138 of the unloading groove 134, it effectively eliminates positional deviations of the mold core 40 during transmission and demolding, while also preventing deformation or damage to the shell due to insufficient support.

[0083] Through the above technical solution, the present invention solves the problems of low positioning accuracy of mold core 40 and unstable shell support in manual operation, realizes reliable fixation of fiber rod 50 during transmission and effective support of protective ring shell during demolding, thereby improving the consistency of injection molding and the qualified rate of finished products.

[0084] In some embodiments, the present invention proposes a first gripping assembly 140 including a second support 141, a first X-axis displacement assembly 142, a first Y-axis displacement assembly, a first Z-axis displacement assembly 144, and at least one clamping assembly 145. The second support 141 is disposed adjacent to the feeding assembly 110. The first X-axis displacement assembly 142 is disposed on the first Y-axis displacement assembly 143, the first Z-axis displacement assembly 144 is disposed on the first Y-axis displacement assembly 143, and the clamping assembly 145 is disposed on the first Z-axis displacement assembly 144. The clamping assembly 145 includes a mounting base 14. 51. A second cylinder 1452, two drive arms 1453, and two clamping arms 1454; a mounting base 1451 is disposed on a first Z-axis displacement assembly 144, a second cylinder 1452 is fixed on a mounting base 1451, drive arms 1453 are connected to the second cylinder 1452, clamping arms 1454 are connected to drive arms 1453, the two clamping arms 1454 are arranged opposite to each other, and one or both clamping arms 1454 are provided with a slot 1455 for clamping fiber rods 50; under the drive of the second cylinder 1452, the two clamping arms 1454 move relative to each other and form a clamping space;

[0085] The structure of the second gripping component is similar to that of the first gripping component. Specifically, the second gripping component 150 includes a third support, a second X-axis displacement component, a second Y-axis displacement component, a second Z-axis displacement component, and a suction cup. The third support is arranged adjacent to the unloading tray 130. The second X-axis displacement component is mounted on the second Y-axis displacement component, the second Z-axis displacement component is mounted on the second Y-axis displacement component, and the suction cup is mounted on the second Z-axis displacement component. One end of the suction cup is connected to an air source, and the other end is connected to the mold core 40 or a protective ring.

[0086] In addition, the feeding tray 130 may include an empty tray pile and a full tray pile, which are arranged adjacent to each other. The protective ring gripped by the second gripping component is placed in the empty tray pile, and after the empty tray is filled, it is transferred to the full tray pile.

[0087] In this embodiment, the first X-axis displacement component 142 refers to a drive unit that moves horizontally, specifically using a ball screw and a servo motor, used to drive the clamping component 145 to adjust its gripping position laterally. The first Y-axis displacement component 143 refers to a drive unit that moves vertically, specifically using a linear guide and a stepper motor, used to control the vertical movement range of the clamping component 145. The first Z-axis displacement component 144 refers to a drive unit that moves vertically, specifically using a cylinder or an electric push rod, used to adjust the lifting height of the clamping component 145. The slot 1455 refers to a groove structure located inside the clamping arm 1454, specifically using a V-shaped or U-shaped cross-section design, used to form a contact surface with the outer contour of the fiber rod 50 to increase clamping stability. The suction cup refers to an actuator that uses negative pressure to adsorb objects, specifically using a rubber vacuum suction cup, with the adsorption and release of the mold core 40 or protective ring controlled by a solenoid valve.

[0088] Specifically, the first gripping component 140, through the coordinated action of the first X-axis displacement component 142, the first Y-axis displacement component 143, and the first Z-axis displacement component 144, enables the clamping component 145 to be precisely positioned at the fiber rod 50 storage location of the feeding component 110. When the second cylinder 1452 drives the two drive arms 1453, the clamping arms 1454 move in opposite directions, clamping the fiber rod 50 through the slots 1455, avoiding uneven clamping force or positional deviation caused by manual operation. The second gripping component 150, through the second X-axis displacement component, the second Y-axis displacement component, and the second Z-axis displacement component, moves the suction cup to the unloading position, using negative pressure adsorption to complete the transfer of the protective ring or mold core 40, avoiding product surface scratches or positioning deviations caused by traditional manual handling. The two sets of gripping components select mechanical clamping and vacuum adsorption methods respectively for the physical characteristics of the fiber rod 50 and the finished protective ring, realizing fully automated operation.

[0089] In addition, the clamping assembly 145 can also be mounted on the upgrade module, which is fixed to the first Z-axis displacement assembly 144, so that the clamping assembly 145 can achieve multi-level upgrade control, making it easier for the clamping assembly 145 to grip the fiber rod 50.

[0090] Compared with existing technologies, traditional manual dispensing processes require operators to manually grasp the fiber rod 50 and position it in the mold, resulting in inconsistent grasping force and placement misalignment. This invention, through the cooperation of a multi-axis displacement component and a dedicated clamp, controls the grasping position error of the fiber rod 50 within the millimeter range. Furthermore, during clamping, the self-adaptive contact between the slot 1455 and the shape of the fiber rod 50 prevents deformation due to excessive clamping force. For the transfer of the finished protective ring, a negative pressure adsorption method replaces the traditional grippers, avoiding surface damage caused by rigid contact and accommodating rapid switching between protective rings of different sizes.

[0091] Through the above technical solutions, this invention solves the technical problems of low efficiency and unstable yield rate of manual operation, and achieves improved positioning accuracy of fiber rod 50 and non-destructive transfer of protective ring. The multi-degree-of-freedom motion of the clamping assembly 145, combined with the structure of the slot 1455, ensures accurate positioning of the fiber rod 50 in the mold core 40, providing a positional reference for subsequent injection molding processes; the negative pressure adsorption method of the suction cup assembly eliminates the mechanical stress on the outer surface of the protective ring by traditional grippers, reducing the defect rate of finished product appearance. The coordinated work of the two sets of gripping assemblies enables the loading, transfer and unloading process of the mold core 40 to form a continuous automated production line, significantly improving the production cycle.

[0092] Example 2:

[0093] Figure 8-15 This paper presents a second embodiment of a protective ring manufacturing apparatus according to the present invention. Based on embodiment 1, this embodiment further describes the molding mechanism 20. The molding mechanism 20 includes an upper mold driving mechanism, an injection molding material mechanism, and a protective ring mold. The protective ring mold includes an upper mold assembly 21, a lower mold assembly 22, and a mold core 40. The upper mold assembly 21 is provided with a first mounting plate 211 and an upper template 212 disposed on the first mounting plate 211. The upper template 212 is provided with an injection port. The lower mold assembly 22 is provided with a second mounting plate 221, a lower template 222, and a plurality of positioning components 223. The lower template 222 and the plurality of positioning components 223 are disposed on the second mounting plate 221, and the positioning components 223 are disposed around the lower template 222. A mold groove is provided in the middle of the lower template 222. The mold core 40 is detachably disposed in the mold groove, and the mold core 40 is provided with a plurality of first grooves 41 for fixing the fiber rod 50. The upper mold driving mechanism is connected to the upper mold assembly 21 of the protective ring mold, and the injection molding material mechanism is connected to the injection port. During mold closing, a protective ring shell is formed by injection molding through the injection port around the fiber rod 50.

[0094] In this embodiment, the upper mold drive mechanism refers to the power device that drives the upper mold assembly 21 to move vertically. Specifically, it can be implemented using a hydraulic cylinder or a servo motor in conjunction with a lead screw structure to achieve precise opening and closing of the upper and lower molds. The injection material mechanism refers to the device that transports molten plastic to the mold cavity. Specifically, it can be implemented using a screw injection molding machine in conjunction with a heated barrel, ensuring uniform material filling by controlling the injection pressure and temperature. The mold core 40 refers to a detachable mold component with a grooved structure. Specifically, it can be made of aluminum alloy or tool steel, and its surface can be coated with an anti-stick coating to facilitate demolding. The mold positioning assembly 223 refers to the auxiliary molding structure arranged around the mold cavity. Specifically, it can be implemented using a split-type slider mechanism to form the complex geometry of the protective ring shell during the injection molding process.

[0095] Specifically, the core component 40 is pre-installed in the mold groove of the lower mold plate 222, and the fiber rod 50 is precisely embedded and fixed in the groove of the core component 40. When the upper mold drive mechanism pushes the upper mold plate 212 and the lower mold plate 222 to close, the positioning component 223 and the upper mold plate 212 together form a sealed injection cavity. The injection molding material mechanism injects molten plastic into the cavity through the injection port, and the plastic evenly wraps around the fiber rod 50 to form a shell. Since the core component 40 adopts a detachable design, after injection molding is completed, it can be removed as a whole with the molded shell by a robot, which facilitates the loading of the fiber rod 50 for the next cycle.

[0096] Compared with existing technologies, traditional manual dispensing processes require the individual positioning and bonding of fiber rods 50. This invention, however, achieves automatic positioning and fixing of the fiber rods 50 through the cooperation of the mold core 40 and the positioning component 223. Simultaneously, it utilizes injection molding to complete the shell molding and fiber rod 50 encapsulation in one step. Existing technologies limit production cycle time due to adhesive curing time; this invention achieves continuous production through cyclic injection molding, and the injection pressure ensures consistent bonding strength between the material and the fiber rods 50.

[0097] Through the above technical solutions, this invention solves the problems of low efficiency and poor product consistency in manual operation. The replaceable design of the mold core 40 adapts to the processing requirements of fiber rods 50 of different specifications. The injection molding process makes the shell and fiber rod 50 form an integral structure, avoiding connection failure caused by insufficient glue curing. The fit between the positioning component 223 and the upper and lower molds ensures the dimensional accuracy of the shell and eliminates the positioning misalignment defects commonly found in manual operation.

[0098] In some embodiments, the present invention proposes that the lower template 222 has a mounting boss 2221 in the middle and a positioning groove 2220 is provided on the outside of the mounting boss 2221, and the mold groove is provided in the middle of the mounting boss 2221; the positioning component 223 has a positioning block 2231, the positioning block 2231 extends into the positioning groove 2220, and the positioning blocks 2231 of multiple positioning components 223 surround the periphery of the mounting boss 2221.

[0099] In this embodiment, the mounting boss 2221 refers to a protruding structure located in the middle of the lower template 222 for positioning the mold core 40. Specifically, it can be implemented using a stepped cylindrical structure, and its outer diameter can form a clearance fit with the inner hole of the mold core 40. The positioning groove 2220 refers to an annular groove formed around the outer side of the mounting boss 2221. Specifically, it can be formed by milling, and its depth can be 1 / 3 to 1 / 2 of the mold groove depth. The mold groove refers to a cavity located in the middle of the mounting boss 2221 for accommodating the mold core 40. Specifically, it can be a rectangular or circular groove structure matching the outer contour of the mold core 40. The positioning block 2231 refers to a forming module located at the end of the positioning assembly 223. Specifically, it can be a split metal block structure, and its inner surface can be machined into a curved surface matching the outer contour of the protective ring.

[0100] Specifically, after the mold core 40 is precisely embedded into the mold groove, the outer peripheral surface of the mounting boss 2221 forms a clearance fit with the inner wall of the mold core 40, ensuring that the mold core 40 does not shift during injection molding. The positioning block 2231 enters the peripheral area of ​​the mounting boss 2221 through the positioning groove 2220, and the encirclement of multiple positioning blocks 2231 forms the complete outer contour of the injection cavity. During mold closing, the positioning blocks 2231 and the upper mold assembly 21 are structurally matched to form a closed injection space. After the molten plastic enters the cavity from the injection port, it is evenly filled along the gap between the positioning blocks 2231 and the mold core 40, and finally forms a protective ring shell of uniform thickness around the fiber rod 50.

[0101] Compared with existing technologies, traditional manual dispensing processes rely on operators manually controlling the glue distribution, making it difficult to ensure the concentricity of the fiber rod 50 and the outer ring of the protective ring. This invention, however, uses the mounting boss 2221 and the mold groove for positioning, combined with a precisely adjustable positioning block 2231 assembly, to ensure that the fiber rod 50 is always in a predetermined position within the mold. The injection-molded protective ring shell and the fiber rod 50 form a mechanical interlocking structure, completely eliminating the positional deviation problem caused by manual operation.

[0102] Through the above technical solution, the present invention achieves precise positioning of the fiber rod 50 within the mold, ensuring that the plastic uniformly wraps around the fiber rod 50 during injection molding and avoiding stress concentration caused by uneven local thickness. The adjustable design of the positioning block 2231 can adapt to the production needs of protective rings of different specifications, significantly reducing mold modification costs while improving product consistency.

[0103] In some embodiments, the present invention proposes that the mounting boss 2221 is further provided with a plurality of first mounting grooves 2223, the first mounting grooves 2223 having a first wire block 2227 inside, and the upper end of the first wire block 2227 being provided with a second wire groove 2228; the positioning block 2231 is provided with a plurality of support platforms 2232; the first wire groove 41, the second wire groove 2228 and the support platforms 2232 are arranged collinearly to accommodate the fiber rod 50.

[0104] In this embodiment, the first mounting groove 2223 refers to a groove structure provided on the mounting boss 2221, which can be implemented as a rectangular or U-shaped groove, used to fix the position of the first wire block 2227. The first wire block 2227 refers to an independent component embedded in the first mounting groove 2223, which can be made of metal or engineering plastic, and its top second wire groove 2228 is used to form a continuous channel with the first wire groove 41 of the mold core 40. The support platform 2232 refers to a platform structure protruding from the surface of the positioning block 2231, which can be implemented as a stepped or flat boss, used to assist in positioning the fiber rod 50 during injection molding. Collinear arrangement means that the central axis of the first wire groove 41, the second wire groove 2228 and the support platform 2232 are aligned, which can be achieved through precision machining or assembly adjustment to ensure that the fiber rod 50 remains in a straight line during injection molding.

[0105] Specifically, multiple first mounting slots 2223 are formed on the mounting boss 2221, and a first wire block 2227 with a second wire groove 2228 is embedded in each slot. Multiple support platforms 2232 are machined on the surface of the positioning block 2231, and the positions of the support platforms 2232 are aligned with the first wire groove 41 and the second wire groove 2228. When the mold core 40 is loaded with the fiber rod 50 and transferred to the mold cavity, one end of the fiber rod 50 is embedded in the first wire groove 41 of the mold core 40, and the other end extends to the surface of the support platform 2232 through the second wire groove 2228. During the mold closing and injection molding process, the fiber rod 50 is constrained by the first wire groove 41, the second wire groove 2228, and the support platform 2232, preventing displacement or deformation due to injection pressure.

[0106] Compared with existing technologies, traditional manual dispensing processes rely on operators manually adjusting the position of the fiber rod 50, which is prone to positioning deviations. This invention, however, achieves fully automatic positioning of the fiber rod 50 through the collinear cooperation of the first groove 41, the second groove 2228, and the support platform 2232, eliminating errors caused by manual intervention. Furthermore, the synergistic effect of the support platform 2232 and the grooves prevents the fiber rod 50 from bending due to uneven pressure during injection molding, whereas in existing technologies, the fiber rod 50 relies solely on the adhesive for fixation, lacking rigid support.

[0107] Through the above technical solution, this invention solves the problem of inaccurate positioning of the fiber rod 50 during injection molding, ensuring that the bonding position of the fiber rod 50 and the protective ring shell is consistent, and avoiding uneven injection molding or structural eccentricity caused by the offset of the fiber rod 50. At the same time, the multi-level positioning structure achieves rigid fixation of the fiber rod 50, reducing manual adjustment steps and improving the degree of automation in production.

[0108] In some embodiments, the present invention proposes that a first mold plate be provided at the end of the positioning block 2231, a second mold plate 2121 be provided on the upper mold plate 212 to cooperate with the first mold plate, the injection cavity be formed by the first mold plate and the second mold plate being molded together, the second mold plate 2121 be provided with a third groove opposite to the support platform 2232, and a plurality of injection ports are uniformly provided on the second mold plate 2121.

[0109] In this embodiment, the first mold plate refers to the disc-shaped structure at the end of the positioning block 2231, which can be made of metal or engineering plastic. Its edge contour forms a complementary shape with the second mold plate 2121, and is used to define the spatial boundary of the injection cavity together with the second mold plate 2121 when the mold is closed. The second mold plate 2121 refers to the mating structure fixed to the upper mold plate 212, which can be installed by bolt connection or inlay. The third groove on its surface corresponds to the position of the support platform 2232, and is used to provide continuous support for the fiber rod 50 during the injection molding process. The injection port refers to the feed channel evenly distributed around the second mold plate 2121, which can be a circular channel with a diameter of 1-3 mm. For example, 24 injection ports are arranged in a ring array at 15-degree intervals to achieve uniform injection of molten material into the cavity.

[0110] Specifically, when the upper mold plate 212 and the lower mold plate 222 are closed, the first mold plate and the second mold plate 2121 interlock to form a closed annular injection cavity. Molten material is simultaneously injected into the cavity from multiple injection ports of the second mold plate 2121. Due to the uniform distribution of the injection ports and the alignment of the third groove and the support platform 2232, the material flows uniformly around the fiber rod 50. During this process, the continuous support structure formed by the third groove and the support platform 2232 prevents the fiber rod 50 from shifting under pressure, while the uniformly distributed injection ports avoid local material accumulation or insufficient filling.

[0111] Compared with existing technologies, traditional manual dispensing processes rely on operators manually controlling the amount and position of adhesive, which easily leads to problems such as uneven adhesive layer thickness and deformation of the fiber rod under stress. This solution achieves automated and uniform control of material encapsulation through a closed injection cavity formed by a mold plate and simultaneous injection through multiple injection ports, eliminating adhesive volume fluctuations and positional deviations caused by manual operation.

[0112] Through the above technical solution, the present invention can ensure that the fiber rod 50 remains stably aligned during injection molding, avoiding bending or displacement of the fiber rod 50 due to uneven local pressure. The uniformly distributed injection ports enable the molten material to form a uniformly thick outer shell coating layer around the fiber rod 50, effectively solving problems such as uneven glue volume and fluctuations in adhesive strength that exist in manual dispensing, and significantly improving the structural consistency and yield of the protective ring shell.

[0113] In some embodiments, the present invention provides a protective ring manufacturing device, wherein the mold core 40 is provided with a first clearance groove 44; a first mold plate is provided with a first column mold 2226, the first column mold 2226 extending from the first mold plate and positioned at the center of the upper mold plate 212; a second mold plate 2121 is provided with a second column mold 2125 that matches the first column mold 2226; during mold closing, the first column mold 2226 and the second column mold 2125 are injection molded to form a support column that connects to the outer shell of the protective ring.

[0114] In this embodiment, the first clearance groove 44 refers to a groove structure formed on the surface of the mold core 40, which can be achieved by milling or stamping. It provides space for the first column mold 2226 and the second column mold 2125 during mold closing, preventing structural interference between the mold core 40 and the column molds. The first column mold 2226 refers to a protrusion structure fixed on the first mold plate, which can be made of metal or hard alloy material. Its extension direction is consistent with the mold closing direction, and it forms the cavity of the supporting column together with the second column mold 2125 during injection molding. The second column mold 2125 refers to a groove or protrusion structure provided on the second mold plate 2121, which can form a complementary shape to the first column mold 2226, such as a columnar groove or annular protrusion. It aligns with the first column mold 2226 during mold closing to form a closed injection channel. The support column refers to a columnar structure formed by curing injection molding material in the gap between the first column mold 2226 and the second column mold 2125. Specifically, it can be integrally molded with the protective ring shell to enhance the connection strength between the shell and the fiber rod 50.

[0115] Specifically, after the mold core 40 is transferred to the mold cavity, the upper mold drive mechanism drives the upper mold plate 212 to move downwards, causing the first column mold 2226 to insert into the corresponding groove or gap of the second column mold 2125. At the same time, the first clearance groove 44 of the mold core 40 provides clearance space for the movement path of the first column mold 2226. After the mold is closed, the injection molding material enters the cavity formed by the first column mold 2226 and the second column mold 2125 through the injection port, and after curing, forms a support column that is integrated with the protective ring shell. This support column directly wraps around the fiber rod 50 or contacts the surface of the fiber rod 50, replacing the traditional manual dispensing bonding method, and realizing the mechanical fixation of the fiber rod 50 to the shell.

[0116] In some specific embodiments, the end of the first column mold 2226 can be designed as tapered or stepped, and the corresponding position of the second column mold 2125 is provided with a matching chamfer structure to ensure precise alignment of the two during mold closing. The diameter of the support column can be 1.2 to 1.5 times the diameter of the fiber rod 50 to balance structural strength and material cost. In addition, the axial length of the support column can be adjusted according to the size of the protective ring, for example, covering 50% to 80% of the total length of the fiber rod 50.

[0117] Compared with existing technologies, which rely on manual dispensing to fix the fiber rods 50, this invention addresses issues such as unstable glue volume control and long curing times. This invention, through the coordinated design of the mold plate and the column mold, directly forms a support column integrated with the outer shell during the injection molding stage. This not only eliminates the dispensing process but also improves connection reliability through mechanical structure. Furthermore, the size and position of the support column are guaranteed by mold precision, avoiding deviations or uneven glue distribution caused by manual operation.

[0118] Through the above technical solution, this invention achieves automated fixing of the fiber rod 50 and the protective ring shell, solving the problems of low efficiency and unstable yield of manual dispensing. The integrated molding design of the support column and the shell enhances the connection strength, avoids the risk of detachment caused by adhesive aging, and reduces waiting time in the production cycle, making it suitable for mass production scenarios.

[0119] In some embodiments, the present invention provides a protective ring manufacturing device, including a molding mechanism 20. The molding mechanism 20 includes a protective ring mold, and the protective ring mold includes an upper mold assembly 21. The upper mold assembly 21 is provided with a first mounting plate 211 and an upper template 212. A pressure plate 2122 and a pressure ring 2124 are provided in the middle of the upper template 212. The pressure ring 2124 is located on the outer periphery of the pressure plate 2122. A plurality of pressing protrusions 2123 are provided at the lower end of the pressure plate 2122. A second groove 2228 is provided with a first slot. When the mold is closed, the pressing protrusions 2123 are pressed onto the fiber rod 50, and the pressure ring 2124 is disposed in the first slot and pressed onto the fiber rod 50.

[0120] In this embodiment, the pressure plate 2122 refers to a metal plate-like structure disposed in the middle of the upper template 212 for applying vertical pressure. It can be made of a high-hardness alloy material, and the pressing protrusion 2123 at its lower end can form partial contact with the surface of the fiber rod 50. The pressure ring 2124 refers to an annular pressing component surrounding the outer periphery of the pressure plate 2122. It can be made of a composite structure of elastic rubber material and a metal skeleton, enabling uniform pressure distribution during mold closing. The first slot refers to a recessed area opened on the surface of the second groove 2228, which can be formed by milling and is used to accommodate the embedded portion of the pressure ring 2124. The pressing protrusion 2123 refers to a protrusion structure distributed at the lower end of the pressure plate 2122, which can be hemispherical or pyramidal in shape and formed by precision stamping.

[0121] Specifically, during the mold closing process, the upper mold assembly 21 drives the pressure plate 2122 and the pressure ring 2124 to move downwards synchronously. The pressing protrusion 2123 first contacts the surface of the fiber rod 50, pressing and fixing the fiber rod 50 into the second groove 2228 through local point pressure; then the pressure ring 2124 is embedded in the first slot, and its annular contact surface applies uniform circumferential pressure to the fiber rod 50. This staged pressure application method not only ensures the precise positioning of the fiber rod 50 before injection molding, but also counteracts the lateral force generated by the flow of molten material during injection molding through annular pressure. The mating structure of the pressure ring 2124 and the first slot forms a physical limit, effectively preventing the fiber rod 50 from axially shifting under the high temperature and high pressure environment 2124.

[0122] Compared to existing technologies, traditional manual dispensing processes rely on operator visual positioning, making it difficult to control application pressure and positional accuracy. This invention achieves fully automated positioning and fixation of the fiber rod 50 through a mechanical pressing structure. The synergistic effect of the pressing protrusion 2123 and the pressure ring 2124 provides multi-directional constraint on the fiber rod 50 in three-dimensional space, completely eliminating positioning deviations caused by manual operation. Compared to traditional methods that rely solely on adhesive curing, mechanical pressing can reliably fix the fiber rod before injection molding, eliminating the need to wait for the adhesive to cure.

[0123] Through the above technical solution, this invention achieves precise positioning and reliable fixation of the fiber rod 50 during the injection molding process. The dual pressing mechanism of the pressing protrusion 2123 and the pressure ring 2124 effectively prevents the fiber rod 50 from shifting under high temperature and high pressure injection molding conditions, ensuring that the bonding position between the protective ring shell and the fiber rod 50 is precise and controllable. This structural design fundamentally solves the problems of uneven glue volume and positioning misalignment in manual dispensing processes, significantly improving product consistency and yield, while shortening the production cycle.

[0124] In some embodiments, the mold core 40 has a guide hole 42 in its center, and a plurality of first limiting grooves 43 are provided on the sidewall of the guide hole 42; the mold groove is provided with a guide post 2224, and a first limiting block 2225 is provided around the guide post 2224; when the mold core 40 moves into the mold groove, the guide hole 42 is inserted along the guide post 2224 and the first limiting block 2225 is engaged with the first limiting groove 43; the mold core 40 is also provided with a first positioning hole 45, and the mold groove is also provided with a first positioning pin; when the mold core 40 moves into the mold groove, the first positioning pin is inserted into the first positioning hole 45. In this embodiment, the present invention enables the mold core 40 to be installed into the mold groove by providing the guide hole 42 and the guide post 2224 in cooperation; and it is fixed by the first limiting block 2225 engaging with the first limiting groove 43. Furthermore, the present invention can further fix the mold core 40 in the mold groove by the cooperation of the first positioning pin and the first positioning hole 45.

[0128] S2, the fiber rod is gripped from the feeding component by the first gripping component, and the fiber rod is placed into the first groove of the mold core in sequence;

[0129] S3, after the core component has completed the loading of fiber rods, the transfer mechanism moves the core component to the middle of the transfer mechanism, and the transfer mechanism grabs the core component and moves it to the mold groove of the molding mechanism.

[0130] S4, the molding mechanism closes the upper mold assembly and the lower mold assembly to injection mold the outer shell of the protective ring in the injection cavity around the fiber rod;

[0131] S5. After the protective ring shell is made, the mold core is moved to the transfer mechanism by the transfer mechanism, and the transfer mechanism transfers the mold core to the unloading tray. The second gripping component grips the protective ring and puts it into the unloading tray.

[0132] Through steps S1-S5, the present invention achieves a continuous production process of automatic loading, injection molding, and finished product unloading of fiber rods through the coordinated action of the loading mechanism, molding mechanism, and transfer mechanism. It has the advantages of improving production efficiency, ensuring product quality stability, and realizing automated production.
