Description

Technical Field

[0001] This invention relates to the field of automated blade assembly technology, and in particular to a blade insertion device and method. Background Technology

[0002] In the manufacturing process of cutting tools, nitriding heat treatment is a key step to improve the surface hardness and wear resistance of the tools. During nitriding, to ensure that the surface of each tool is in full contact with the nitriding medium and to avoid uneven nitriding caused by tool stacking, multiple tools need to be separated before heat treatment.

[0003] In existing technologies, blades and spacers are typically threaded alternately onto iron wire or wire using a manual method to form a flexible blade string before being fed into the nitriding furnace. Operators first straighten and fix an iron wire, then manually thread spacers and blades one by one, relying on the spacers to separate adjacent blades and ensure that the blade surface can fully contact the nitriding gas during the nitriding process. However, in actual production, due to the low rigidity and high deflection of the iron wire itself, the end of the wire tends to droop and swing during threading, making it difficult to guarantee the coaxiality between the inner hole of the blade and the end of the iron wire. Using the existing direct insertion method, problems such as misalignment, jamming, and even bending and deformation of the iron wire are prone to occur, resulting in a high threading failure rate and poor equipment operational stability, failing to meet the needs of industrial mass production. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a blade-piercing device that can automatically, accurately, and efficiently pierce the blade and sleeve, improve the success rate of piercing and the stability of the equipment, and meet the needs of industrial mass production.

[0005] The present invention also proposes a method for piercing a blade using the piercing device.

[0006] According to a first aspect of the present invention, the blade-piercing device includes: a frame, a first feeding mechanism, a second feeding mechanism, a third feeding mechanism, and a blade-piercing execution mechanism. The first feeding mechanism is disposed on the frame and provides a blade-piercing frame for piercing blades and sleeves. The second feeding mechanism is disposed on the frame and provides the sleeves, which can be fitted onto the blade-piercing frame to allow the blades to be spaced apart on the frame. The third feeding mechanism is disposed on the frame and provides the blades. The blade-piercing execution mechanism is disposed on the frame and located to one side of the first feeding mechanism. The blade-piercing execution mechanism includes an assembly component and an assembly positioning component, which are slidably disposed on the frame. The assembly component can respectively clamp the sleeves and the blades and assemble the sleeves and blades onto the blade-piercing frame. The assembly positioning component supports and positions the blades and the sleeves.

[0007] According to the first aspect of the present invention, the cutting device has at least the following beneficial effects: by setting up a first feeding mechanism, a second feeding mechanism, and a third feeding mechanism, the automatic supply of the cutting frame, sleeve, and blade is realized, replacing the inefficient method of manual feeding one by one, laying the foundation for automated cutting; by setting up a cutting execution mechanism, and enabling the assembly components therein to clamp the sleeve and blade for assembly, the automated execution of the cutting action is realized, avoiding fatigue and errors caused by manual operation; in particular, by setting up an assembly positioning component, the cutting frame, blade, and sleeve are supported and positioned during the assembly process, effectively solving the problem in the prior art that the coaxiality between the inner hole of the blade and the end of the cutting frame is difficult to guarantee due to the low stiffness of the iron wire and the easy swinging and sagging of the end. Through stable positioning support, the deviation of the hole and jamming during the cutting process are prevented, improving the success rate of cutting and the stability of equipment operation, thereby meeting the requirements of efficiency and reliability for industrial mass production.

The lifting module is disposed on the frame and located on one side of the fitting frame. The blade holder is slidably disposed on the output end of the lifting module and can clamp the fitting frame and support the blade and the sleeve. The positioning clamp is disposed on the frame and located directly above the blade holder and can clamp the end of the fitting frame to position the blade and the sleeve.

[0009] According to some embodiments of the present invention, the assembly assembly includes: a first drive module, a first fitting module, and a second fitting module. The first drive module is disposed on the frame; the first fitting module is slidably disposed on the first drive module, and its output end is provided with two first clamping members, which are slidably disposed on the first fitting module. The first clamping members are capable of clamping the sleeve from the second feeding mechanism onto the fitting frame, and the distance between the two first clamping members is the distance between the two cutter shaft holes on the blade; the second fitting module is slidably disposed on the first drive module, and its output end is provided with a second clamping member, which is slidably disposed on the second fitting module. The second clamping member is capable of clamping the blade from the third feeding mechanism onto the fitting frame.

[0010] According to some embodiments of the present invention, the first clamping member is disposed on the output end of the first dressing module via a first variable pitch module.

[0011] According to some embodiments of the present invention, the first feeding mechanism includes a stepping conveyor module, on which a tooling fixture is provided. The tooling fixture is used to install the fitting frame, which is fixed to the stepping conveyor module by the tooling fixture. The fitting frame is movable along the conveying direction of the stepping conveyor module.

[0012] According to some embodiments of the present invention, the second feeding mechanism includes: a material tray, a first feeding component, and a first pushing module. The material tray is disposed on the frame and is used to store the sleeve. The first feeding component is slidably disposed on the frame and is provided with a receiving hole. The receiving hole is connected to the discharge end of the material tray through a feeding pipe. The first pushing module is disposed on the frame and located on one side of the first feeding component. The output end of the first pushing module is connected to the first feeding component, and the first pushing module is used to drive the first feeding component to reciprocate.

[0013] According to some embodiments of the present invention, the third feeding mechanism includes: a magazine assembly, a gripping assembly, and a second feeding assembly. The magazine assembly is disposed on the frame and is used to store the blade; the gripping assembly is disposed on the frame and includes a gripping member and a second drive module, the gripping member being disposed on the output end of the second drive module, the second drive module being used to drive the gripping member to grip the blade; the second feeding assembly is disposed on the frame and includes two material carriers for supporting the blade, the distance between the two material carriers being adjustable; and a second pushing module, the second pushing module being disposed on the frame and located on one side of the second feeding assembly, the second pushing module being used to push the blade to position the blade.

[0014] According to some embodiments of the present invention, the material carrier is slidably mounted on the frame via a second pitch module.

[0015] According to some embodiments of the present invention, the magazine assembly includes: a hopper, a support plate, and a spacing adjustment seat. The hopper includes two side plates arranged opposite each other, and the spacing between the two side plates is adjustable. The blades can be stacked and stored between the side plates. The support plate is disposed on the frame via a third drive module and is used to support the blades. The spacing adjustment seat is slidably disposed on the frame, and the side plates are respectively disposed on the two spacing adjustment seats.

[0016] According to a second aspect of the present invention, a knife-piercing method is applied to the knife-piercing device described in the first aspect of the present invention, the knife-piercing method comprising the following steps: S1. The first feeding mechanism moves the garment frame to below the assembly assembly and to one side of the lifting module, so that both the positioning clamp and the knife clamp can clamp the garment frame. At this time, the positioning fingers of the positioning clamp are in the closed state. S2. The two first clamping members clamp the sleeve from the second feeding mechanism and assemble the sleeve onto the fitting frame through the first fitting module. At this time, the positioning fingers of the positioning clamping member switch from the closed state to the open state so that the sleeve can slide onto the knife clamping member. S3. The positioning fingers of the positioning clamping member are switched from the open state to the closed state so that the positioning fingers of the positioning clamping member clamp the dressing frame. The second clamping member clamps the blade from the third feeding mechanism and assembles the blade onto the dressing frame through the second dressing module so that the blade can slide onto the positioning clamping member. S4. Open the positioning finger clamp of the positioning clamp so that the blade on the positioning clamp slides down to the sleeve below, and then switch the positioning finger of the positioning clamp from the open state to the closed state. S5. Repeat steps S2 to S3, sequentially threading the sleeve in the second feeding mechanism and the blade in the third feeding mechanism onto the threading frame to complete the alternating arrangement of the blade and the sleeve on the threading frame. S6. After the blade and the sleeve are installed, the installation frame is moved out of the installation station by the first feeding mechanism to facilitate the unloading of the installation frame.

[0017] The blade insertion method according to the second aspect of the present invention has at least the following beneficial effects: by moving the insertion frame to a stable positioning station composed of a blade holder and a positioning clamp, a reliable reference is provided for subsequent insertion; by first inserting the sleeve and letting it slide down to be supported by the blade holder, then using the positioning clamp to hold the end of the insertion frame before inserting the blade and letting it slide down to the positioning clamp, and finally releasing the positioning clamp so that the blade accurately falls on the sleeve below, this cyclical operation process utilizes gravity sliding and step-by-step positioning to replace the traditional easily deformable iron wire, ensuring that the sleeve and blade can be inserted in sequence and accurately under the premise that the insertion frame is stably supported and positioned, avoiding the problems of misalignment and jamming caused by the shaking of the end of the insertion frame or misalignment, thereby realizing an efficient, stable and reliable automated insertion process, improving insertion quality and production efficiency.

[0023] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 4According to a first aspect embodiment of the present invention, the piercing device includes: a frame 10, a first feeding mechanism 20, a second feeding mechanism 30, a third feeding mechanism 40, and a piercing execution mechanism 50. The first feeding mechanism 20 is mounted on the frame 10 and is used to provide the mounting frame 3 for mounting the blade 1 and the sleeve 2. The second feeding mechanism 30 is mounted on the frame 10 and is used to provide the sleeve 2, which can be fitted onto the mounting frame 3 to arrange the blade 1 at intervals on the mounting frame 3. The third feeding mechanism 40 is mounted on the frame 10 and is used to provide the blade 1. The mounting execution mechanism 50 is mounted on the frame 10 and located on one side of the first feeding mechanism 20. The mounting execution mechanism 50 includes an assembly component 51 and an assembly positioning component 52, which are slidably mounted on the frame 10. The assembly component 51 can respectively clamp the sleeve 2 and the blade 1 and assemble the sleeve 2 and the blade 1 onto the mounting frame 3. The assembly positioning component 52 is used to support and position the blade 1 and the sleeve 2.

[0025] Specifically, the frame 10, as the basic support structure of the entire equipment, is usually constructed by welding or assembling profiles, providing an installation reference for all other mechanisms. The first feeding mechanism 20, the second feeding mechanism 30, the third feeding mechanism 40, and the loading execution mechanism 50 are all fixedly mounted on their respective worktables on the frame 10 by bolts or other connecting parts.

[0026] The first feeding mechanism 20 is responsible for conveying the mounting frame 3, such as a steel shaft, to the mounting station; the second feeding mechanism 30 is responsible for storing and orderly supplying the sleeves 2, which are metal spacer sleeves; the third feeding mechanism 40 is responsible for storing and orderly supplying the blades 1, such as razor blades, paper cutter blades, etc. The mounting execution mechanism 50 is located above the conveying path of the first feeding mechanism 20, and its assembly component 51 can slide on the frame 10 to reach the picking positions of the second feeding mechanism 30 and the third feeding mechanism 40, as well as the mounting station of the first feeding mechanism 20. The assembly component 51 performs gripping and transferring actions, sequentially mounting the sleeves 2 of the second feeding mechanism 30 and the blades 1 of the third feeding mechanism 40 onto the mounting frame 3. The assembly positioning component 52 is also slidable and moves to the lower end and side of the dressing frame 3 during the dressing process. It provides stable support and clamping positioning for the overhanging end of the dressing frame 3, that is, the upper end of the dressing frame 3, to prevent it from swaying and sagging due to its own weight or force. This ensures that the blade shaft hole of the blade 1 can be accurately aligned with the dressing frame 3, thereby improving the success rate and stability of the dressing.

[0027] Furthermore, referring to Figures 3 to 4In some embodiments of the present invention, the assembly positioning component 52 includes a lifting module 521, a blade holder 522, and a positioning holder 523. The lifting module 521 is disposed on the frame 10 and located on one side of the fitting frame 3; the blade holder 522 is slidably disposed on the output end of the lifting module 521, and the blade holder 522 can clamp the fitting frame 3 and support the blade 1 and the sleeve 2; the positioning holder 523 is disposed on the frame 10 and located directly above the blade holder 522, and the positioning holder 523 can clamp the end of the fitting frame 3 to position the blade 1 and the sleeve 2.

[0028] Specifically, the lifting module 521 can be a linear motor module, cylinder, or lead screw slide, etc., with its base fixed on the frame 10, and its sliding direction parallel to the axis of the insertion frame 3. The knife holder 522 is installed on the slider of the lifting module 521 and can move up and down with the lifting module 521. The knife holder 522 typically has a V-shaped or U-shaped support groove (not shown in the figure) and a gripper. The support groove is used to temporarily support the inserted sleeve 2 and the inserted blade 1 during the insertion process, while the gripper is used to clamp the insertion frame 3 from the side, providing additional lateral positioning.

[0029] The positioning clamp 523 is fixedly mounted on the crossbeam or bracket of the frame 10, precisely aligned with the insertion station, and located directly above the tool holder 522. The positioning clamp 523 is typically a pair of openable pneumatic fingers or electric grippers used to clamp the end of the insertion frame 3 from above and below, providing precise axial and radial positioning. During the insertion cycle, the positioning clamp 523 is fixed to the crossbeam or bracket of the frame 10. When the assembly assembly 51 of the insertion actuator 50 sequentially inserts the sleeve 2 and the blade 1 onto the insertion frame 3, the positioning clamp 523 clamps and fixes the upper end of the insertion frame 3 to facilitate the insertion of the sleeve 2 and the blade 1 by the assembly assembly 51. After the assembly assembly 51 has sequentially inserted the sleeve 2 and the blade 1 onto the insertion frame 3, the positioning clamp 523 opens its openable fingers or grippers, allowing the sleeve 2 and the blade 1 to slide down onto the tool holder under gravity. To assemble the assembly 51, the sleeve 2 and the blade 1 are cyclically threaded onto the threading frame 3. During this process, the blade holder 522 constantly clamps the two steel columns of the threading frame 3 and, driven by the lifting module 521, gradually moves downward as the sleeve 2 and blade 1 are threaded, simultaneously supporting the threaded sleeve 2 and blade 1. Therefore, it can be inferred that the blade holder 522 and the positioning holder 523 work alternately to jointly ensure the stability of the end of the threading frame 3 when the blade 1 and sleeve 2 are threaded.

[0030] Reference Figures 1 to 3In some embodiments of the present invention, the assembly component 51 includes: a first drive module 511, a first fitting module 512, and a second fitting module 513. The first drive module 511 is mounted on the frame 10; the first fitting module 512 is slidably mounted on the first drive module 511, and the output end of the first fitting module 512 is provided with two first clamping members 5121. The two first clamping members 5121 are slidably mounted on the first fitting module 512, and the first clamping members 5121 can clamp the sleeve 2 from the second feeding mechanism 30 to the fitting frame 3. The distance between the two first clamping members 5121 is the distance between the two cutter shaft holes on the blade 1; the second fitting module 513 is slidably mounted on the first drive module 511, and the output end of the second fitting module 513 is provided with a second clamping member 5131. The second clamping member 5131 is slidably mounted on the second fitting module 513, and the second clamping member 5131 can clamp the blade 1 from the third feeding mechanism 40 to the fitting frame 3.

[0031] Specifically, the first drive module 511 is typically a long-stroke linear module, horizontally mounted on the frame 10, with its sliding direction perpendicular to the axis of the insertion frame 3. The first insertion module 512 and the second insertion module 513 are mounted side-by-side on the slider of the first drive module 511 and can be driven by the first drive module 511 to reciprocate between the material handling positions, i.e., the insertion positions corresponding to the second feeding mechanism 30, the third feeding mechanism 40, and the first feeding mechanism 20. The first insertion module 512 itself is also a module with vertical motion capabilities, such as a cylinder or an electric slide, and its slider is equipped with two first clamping members 5121. The first clamping members 5121 can be pneumatic grippers, specifically designed to grip slender sleeves 2. The distance between the two first clamping members 5121 is set to match the distance between the two coaxial cutter shaft holes on the blade 1 to be inserted, thereby enabling the simultaneous insertion of two sleeves 2 in a single action. The second fitting module 513 also has a vertical movement function. A second clamping component 5131 is installed on its slider. The second clamping component 5131 can be a vacuum suction cup, a magnetic gripping finger, or a special gripper, used to pick up or clamp the blade 1. Through the lateral movement of the first drive module 511 and the vertical movement of the two fitting modules, the automatic gripping and precise fitting of the sleeve 2 and the blade 1 are realized.

[0032] It should be noted that the simultaneous insertion of the two first clamping members 5121 into the two sleeves 2 in one operation is designed based on the two steel columns of the insertion frame 3. The two steel columns of the insertion frame 3 can be used to fix the blade 1 and prevent the blade 1 from rotating. Therefore, it should also be noted that in this embodiment of the invention, there is no specific limitation on the number of steel columns of the insertion frame 3 and the number of first clamping members 5121, as long as the number is greater than or equal to 2.

[0033] Furthermore, referring to Figures 1 to 3 In some embodiments of the present invention, the first clamping member 5121 is disposed on the output end of the first inserting module 512 via the first pitch-changing module 5122. The first pitch-changing module 5122 may be a double-guide rail lead screw module, a gear rack mechanism, or a synchronous belt mechanism, etc. The base of the first pitch-changing module 5122 can be fixed on the slider of the first inserting module 512. The two first clamping members 5121 are respectively mounted on the two movable sliders of the first pitch-changing module 5122. By driving the first pitch-changing module 5122, the center distance between the two first clamping members 5121 can be adjusted. This design enables the inserting device to adapt to blades 1 of different models and different blade shaft hole spacings, improving the versatility of the device. When changing products, it is only necessary to adjust the first pitch-changing module 5122 through the control system so that the distance between the two first clamping members 5121 matches the hole spacing of the new blade, without replacing the hardware.

[0034] Reference Figures 1 to 4 In some embodiments of the present invention, the first feeding mechanism 20 includes a stepping conveyor module 21, on which a tooling fixture 22 is provided. The tooling fixture 22 is used to install the mounting frame 3. The mounting frame 3 is fixed on the stepping conveyor module 21 by the tooling fixture 22. The mounting frame 3 can move along the conveying direction of the stepping conveyor module 21.

[0035] Specifically, the stepping conveyor module 21 can be a synchronous belt conveyor, a chain conveyor, or a precision linear module, arranged along the length of the frame 10. Tooling fixtures 22 are fixed at intervals on the conveyor belt or slider of the stepping conveyor module 21. Each tooling fixture 22 has a V-groove or positioning hole for placing and initially positioning the fitting frame 3. The fitting frame 3 can be placed into the tooling fixture 22 manually or automatically. When the equipment starts, the stepping conveyor module 21, according to a preset rhythm, steps the tooling fixture 22 loaded with the fitting frame 3 to the fitting station below the fitting actuator 50. After completing one fitting cycle (fitting a set of sleeves and blades), the stepping conveyor module 21 advances one step, aligning the next section of the fitting frame 3 to be fitted with the fitting actuator 50, until the entire fitting frame 3 is fitted. Finally, the finished product is conveyed to the unloading position.

[0036] Reference Figures 1 to 4 as well as Figure 5In some embodiments of the present invention, the second feeding mechanism 30 includes: a material tray 31, a first feeding component 32, and a first pushing module 33. The material tray 31 is disposed on the frame 10 and is used to store the sleeve 2. The first feeding component 32 is slidably disposed on the frame 10 and is provided with a receiving hole 321. The receiving hole 321 is connected to the discharge end of the material tray 31 through a feeding pipe 322. The first pushing module 33 is disposed on the frame 10 and located on one side of the first feeding component 32. The output end of the first pushing module 33 is connected to the first feeding component 32, and the first pushing module 33 is used to drive the first feeding component 32 to slide back and forth.

[0037] Specifically, the material tray 31 can be a vibratory feeder or a stepped hopper with an internal spiral track for orienting and sorting a large number of bulk sleeves 2, and outputting them one by one from the outlet. The feeding pipe 322 connects the outlet of the material tray 31 to the receiving hole 321 on the first feeding assembly 32, guiding the sorted sleeves 2 to the receiving hole 321. The first feeding assembly 32 is a slider or pusher that can slide linearly within a small range, with its sliding direction perpendicular to the axis of the sleeve 2. The first pushing module 33 can be a small cylinder or electric push rod, with its piston rod or push rod connected to the first feeding assembly 32. During operation, the sleeves 2 fall from the feeding pipe 322 into the receiving hole 321 for temporary storage. When material needs to be picked up, the first pushing module 33 activates, pushing the first feeding component 32, along with the sleeve 2 inside its receiving hole 321, outward to move it to the preset picking position. At this time, one end of the sleeve 2 extends outward, making it easier for the first clamping member 5121 to clamp it. After picking up the material, the first pushing module 33 retracts, driving the first feeding component 32 to reset, ready to receive the next sleeve 2.

[0038] Reference Figures 1 to 4 as well as Figure 6 In some embodiments of the present invention, the third feeding mechanism 40 includes: a magazine assembly 41, a gripping assembly (not shown in the figure), a second feeding assembly 42, and a second pushing module 43. The magazine assembly 41 is disposed on the frame 10 and is used to store the blade 1; the gripping assembly is disposed on the frame 10 and includes a gripping member and a second drive module. The gripping member is disposed on the output end of the second drive module, and the second drive module is used to drive the gripping member to grip the blade 1; the second feeding assembly 42 is disposed on the frame 10 and includes two material carriers 421 for carrying the blade 1, and the distance between the two material carriers 421 is adjustable; the second pushing module 43 is disposed on the frame 10 and located on one side of the second feeding assembly 42, and the second pushing module 43 is used to push the blade 1 to position the blade 1.

[0039] Specifically, the magazine assembly 41 is used for batch storage of blades 1, with a large capacity that reduces the frequency of manual refilling. The gripping assembly is responsible for removing the blades 1 from the magazine assembly 41 and transferring them to the second feeding assembly 42. The gripping device can be a vacuum suction cup, a permanent magnet gripping pneumatic finger, or a chuck, driven by a second drive module, typically a multi-axis robot or an XY module, to complete the pick-and-place action from the magazine to the loading seat 421. The second feeding assembly 42 is the positioning and delivery platform for the blades 1. Two loading seats 421 are arranged opposite each other, and each loading seat 421 has a positioning groove that matches the length of the blade 1. The blade 1 is placed between the two loading seats 421, and the blade shaft holes at both ends are initially positioned by the positioning plates at the ends of the two loading seats 421. The second pushing module 43 can be a linear actuator with a push block mounted at the front end of its push rod. After the blade 1 is placed on the carrier 421, the second pushing module 43 is activated, pushing the blade 1 from the side, so that the blade 1 moves in the positioning groove of the carrier 421 until the side of the blade 1 is in contact with the positioning plate on the carrier 421, thereby eliminating the gap and achieving precise positioning of the blade 1, which is ready for the subsequent gripping of the second clamping member 5131.

[0040] Furthermore, as can be seen from the foregoing embodiments, in some embodiments of the present invention, reference is made to... Figure 6 The material carrier 421 is slidably mounted on the frame 10 via the second pitch-changing module 422. Similar to the first pitch-changing module 5122, the second pitch-changing module 422 has a similar structure and can be a lead screw and nut pair or a synchronous belt drive mechanism. The two material carriers 421 are respectively mounted on the two sliders of the second pitch-changing module 422. By driving the second pitch-changing module 422, the center distance between the two material carriers 421 can be adjusted synchronously. This design allows the second feeding assembly 42 to adapt to blades 1 of different widths and different blade shaft hole spacings. When the equipment switches product models, the second pitch-changing module 422 and the first pitch-changing module 5122 need to be adjusted in conjunction to ensure that the positioning distance of the material carriers 421 is consistent with the material picking distance of the first clamping member 5121, thereby ensuring that the correspondence between the blade 1 and the sleeve 2 on the mounting frame 3 is always accurate.

[0041] Reference Figure 6 In some embodiments of the present invention, the magazine assembly 41 includes: a magazine 411, a support plate 412, and a spacing adjustment seat 414. The magazine 411 includes two side plates 4111 arranged opposite to each other, and the spacing between the two side plates 4111 is adjustable. The blades 1 can be stacked and stored between the side plates 4111. The support plate 412 is arranged on the frame 10 through a third drive module 413 and is used to support the blades 1. The spacing adjustment seat 414 is slidably arranged on the frame 10, and the side plates 4111 are respectively arranged on the two spacing adjustment seats 414.

[0042] The main body of the hopper 411 consists of two parallel side plates 4111, forming an adjustable-width storage channel. The inner lower edge of the side plates 4111 may have a guide ramp to facilitate the stacking of the blades 1. The two side plates 4111 are respectively fixed to two independent spacing adjustment seats 414, which are mounted on the frame 10 via guide rails and adjusted in position by a manual screw or motor drive, thereby changing the width between the two side plates 4111 to accommodate blades 1 of different sizes. A support plate 412 is located at the bottom of the hopper 411, and its top surface supports the weight of all the blades 1. The third drive module 413, which can be a cylinder or an electric lifting mechanism, is installed below the frame 10. As the topmost blade 1 is removed, the third drive module 413 periodically drives the support plate 412 to rise one step, lifting all the blades 1 upwards, ensuring that the topmost blade 1 is always at a height easily grasped by the gripping component, thus achieving automatic replenishment.

[0043] A knife-piercing method according to some embodiments of a second aspect of the present invention, the method being applied to a knife-piercing device according to a first aspect embodiment.

[0044] The cutting method includes the following steps: S1, the cutting frame is moved to the bottom of the assembly component and located on one side of the lifting module by the first feeding mechanism so that the positioning clamp and the knife holder can clamp the cutting frame. At this time, the positioning fingers of the positioning clamp are in the closed state. S2. The two first clamping members clamp the sleeve from the second feeding mechanism and assemble the sleeve onto the insertion frame through the first insertion module. At this time, the positioning fingers of the positioning clamping member switch from the closed state to the open state so that the sleeve can slide onto the knife clamping member. S3. The positioning fingers of the positioning clamping member switch from the open state to the closed state so that the positioning fingers of the positioning clamping member clamp the mounting frame. The second clamping member picks up the blade from the third feeding mechanism and assembles the blade onto the mounting frame through the second mounting module so that the blade can slide onto the positioning clamping member. S4. Open the positioning finger clamp of the positioning clamp so that the blade on the positioning clamp slides down to the lower sleeve, and then switch the positioning finger of the positioning clamp from the open state to the closed state. S5. Repeat steps S2 to S3 to sequentially thread the sleeves in the second feeding mechanism and the blades in the third feeding mechanism onto the threading frame in a cyclical manner, so as to complete the alternating arrangement of the blades and sleeves on the threading frame. S6. After the blade and sleeve are installed, the first feeding mechanism moves the installation frame out of the installation station to facilitate the unloading of the installation frame.

[0045] Specifically, in step S1, the stepping conveying module 21 of the first feeding mechanism 20 starts according to a preset program, precisely moving the tooling fixture 22 loaded with the fitting frame 3 along the conveying direction to the fitting station below the fitting execution mechanism 50. At this time, the section to be fitted (usually the end) of the fitting frame 3 is exactly below the movement trajectory of the assembly component 51 and to the side of the lifting module 521. The assembly positioning component 52 simultaneously starts a preparatory action: the lifting module 521 drives the knife holder 522 to rise to a preset support height, so that its V-shaped or U-shaped support groove is aligned with the lower surface of the overhanging end of the fitting frame 3; the positioning holder 523 moves from the initial position to directly above the end of the fitting frame 3. In the initial state, the positioning fingers (i.e. grippers) of the positioning clamp 523 are in the closed state, which means that when the garment frame 3 moves to the garment station, the two fingers of the positioning clamp 523 and the tool holder clamp 522 are together to clamp the end of the garment frame 3, preparing for garmenting.

[0046] In step S2, assembly component 51 begins the insertion of sleeves 2. First drive module 511 first drives first insertion module 512 to the picking position of second feeding mechanism 30. First push module 33 of second feeding mechanism 30 has already pushed sleeves 2 to the picking position. First insertion module 512 descends, and its two first clamping members 5121 at the output end simultaneously clamp one sleeve 2 each. Then, first insertion module 512 rises, and first drive module 511 drives it back above the insertion station. At this time, first insertion module 512 descends again, aligning the two sleeves 2 with the ends of insertion frame 3. During the insertion process, the control system of positioning clamping member 523 issues a command to switch its positioning fingers from the closed state to the open state (i.e., the two fingers separate and spread). The timing of this state transition is precisely controlled to ensure that after the sleeve 2 passes through the end of the insertion frame 3, the fingers of the positioning clamp 523 are open and no longer constrain the end of the insertion frame 3. Under the action of gravity, the sleeve 2 can smoothly slide down the insertion frame 3. Finally, the sleeve 2 slides into the support groove of the knife holder 522, which is already in place below, and is temporarily supported and positioned by the knife holder 522.

[0047] In step S3, after the sleeve 2 successfully slides onto the tool holder 522, the positioning holder 523 immediately actuates, and its positioning fingers switch from the open state to the closed state. This closing action performs the clamping function: the two fingers close and clamp the end of the inserting frame 3. This clamping action provides a precise and stable reference point for inserting the blade 1, eliminating any slight wobbling that may exist at the end of the inserting frame 3, and ensuring absolute coaxiality between the tool shaft hole and the inserting frame 3. At the same time, another part of the assembly assembly 51 begins to perform the inserting operation of the blade 1. Driven by the first drive module 511, the second inserting module 513 moves to the picking position of the third feeding mechanism 40. The second feeding component 42 of the third feeding mechanism 40 has precisely positioned the blade 1 on the carrier 421. The second inserting module 513 descends, and the second clamping member 5131 at its output end picks up or clamps the blade 1. Then the second inserting module 513 rises and returns to above the inserting station. Since the positioning clamp 523 has firmly clamped the end of the fitting frame 3, the two blade shaft holes of the blade 1 can be aligned with the fitting frame 3. The second fitting module 513 descends and inserts the blade 1 into the fitting frame 3. After the blade 1 is inserted, it slides down the fitting frame 3 under the action of gravity. However, since the fingers of the positioning clamp 523 are in a closed clamping state, the blade 1 will be blocked by the upper surface of the fingers of the positioning clamp 523 after sliding down, and thus stay on the positioning clamp 523.

[0048] In step S4, after the blade 1 rests on the positioning clamp 523, the control system instructs the positioning fingers of the positioning clamp 523 to switch from the closed state to the open state again. With the fingers open, the blade 1 is no longer obstructed and slides freely downwards under gravity. Since the two sleeves 2 inserted in step S2 are already supported on the lower tool holder 522, and the positions of the sleeves 2 correspond vertically to the positions of the blade shaft holes of the blade 1, the falling blade 1 will land precisely on the two sleeves 2. The weight of the blade 1 presses down on the sleeves 2 below, completing the stacked assembly of the blade 1 and the sleeves 2. Immediately after the blade 1 slides down, the positioning fingers of the positioning clamp 523 immediately switch from the open state back to the closed state, preparing to switch to the open state in the next cycle's step S2 (sleeve insertion).

[0049] In step S5, the execution is cyclical to achieve continuous automated production. After completing the assembly of the first "sleeve and blade" unit, the equipment automatically enters the next cycle. Step S2 is repeated: with the positioning clamp 523 fingers closed, the first clamp 5121 picks up the sleeve 2 and inserts it. At this time, the positioning clamp 523 fingers open, allowing the sleeve 2 to slide onto the insertion frame 3 section already equipped with the blade 1 (i.e., onto the previous blade 1). Then, step S3 is repeated: the positioning clamp 523 fingers close, clamping the insertion frame 3, and the second clamp 5131 picks up the blade 1 and inserts it, allowing the blade 1 to slide onto the positioning clamp 523. Step S4 is then repeated: the positioning clamp 523 fingers open, and the blade 1 slides onto the newly inserted sleeve 2. This cycle continues. After each cycle is completed, the lifting module 521 of the assembly positioning component 52 will make a small step movement, so that through multiple cycles, the fitting frame 3 will eventually form a closely arranged string structure with alternating blades 1 and sleeves 2 on the entire fitting frame 3, which is ready for the subsequent nitriding heat treatment.

[0050] In step S6, when the control system detects that the preset number of blades 1 and sleeves 2 have been fully installed (e.g., the mounting frame 3 is full), or the preset number of blades has been reached, the cycle stops. The assembly positioning component 52 is reset: the fingers of the positioning clamp 523 open and move to a safe position, and the lifting module 521 drives the blade holder 522 to descend and release its support of the mounting frame 3. Then, the stepping conveyor module 21 of the first loading mechanism 20 starts, moving the mounting frame 3 (along with its tooling fixture 22) fully loaded with blades 1 and sleeves 2 from the mounting station along the conveying direction to the downstream unloading station or buffer area. At the unloading station, the installed blade string can be removed from the tooling fixture 22 manually or automatically and transferred to the subsequent heat treatment process. Simultaneously, the empty tooling fixture 22 can be reloaded with a new mounting frame 3, preparing for the next production cycle.

[0051] By moving the mounting frame 3 to a stable positioning station composed of the knife holder 522 and the positioning clamp 523, a reliable benchmark is provided for subsequent mounting. The process involves first inserting the sleeve 2 and letting it slide down to be supported by the knife holder 522, then using the positioning clamp 523 to hold the end of the mounting frame 3 before inserting the blade 1 and letting it slide down to the positioning clamp 523, and finally releasing the positioning clamp 523 so that the blade falls precisely onto the sleeve 2 below. This cyclical operation process utilizes gravity sliding and step-by-step positioning to replace the traditional easily deformable iron wire. It ensures that, under the premise that the mounting frame 3 is stably supported and positioned, the sleeve 2 and the blade 1 can be inserted in sequence and accurately. This avoids problems such as misalignment or jamming caused by the shaking of the end of the mounting frame 3 or inaccurate alignment. Thus, an efficient, stable, and reliable automated mounting process is achieved, improving mounting quality and production efficiency.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
