Description

Technical Field

[0001] This invention relates to the field of cemented carbide production equipment technology, specifically to a cemented carbide product rod threading device. Background Technology

[0002] In the production of cemented carbide products (such as cemented carbide cutting tools, including drills, end mills, turning tools, reamers, etc.), surface coating is a key process to improve the wear resistance and extend the service life of the products. This coating process typically requires multiple cemented carbide products (with holes) to be sequentially threaded onto a dedicated feed rod carrier, and then fed as a whole into coating equipment for vacuum coating or chemical vapor deposition. Under certain product models and specific process requirements, to prevent adjacent products from contacting and sticking together or to avoid uneven coating during the coating process, springs or spacer beads are also required between adjacent products on the same feed rod carrier to ensure that the products maintain a preset distance and are separated from each other.

[0003] Traditionally, the insertion of cemented carbide products onto poles has relied primarily on manual labor, resulting in high labor intensity, low efficiency, and high production costs. Existing automated pole-insertion equipment typically uses a fixing device to secure the lower end of a pole carrier. A robotic arm then transfers the cemented carbide product to the top of the pole carrier, aligns it with the upper end, and releases the product, allowing it to fall directly onto the pole carrier under gravity. However, this method has several problems: First, the product falls directly from the release point onto the bottom of the carrier or onto an already inserted product, resulting in a significant drop and increasing the risk of damage from impact. Second, to insert the product along the full length of the pole carrier, only the lower end is usually fixed. Because the pole carrier is slender and flexible, fixing only the lower end allows the upper part to wobble, making accurate alignment with the product held by the robotic arm difficult, thus affecting the precision and stability of the insertion operation. These problems are particularly pronounced when the pole carrier is long. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a cemented carbide product pole-threading device that is not prone to collision damage and has high accuracy and stability in pole-threading operations.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cemented carbide product threading device includes one or more threading units. Each threading unit includes a lower fixing component for fixing the lower part of a material rod carrier and keeping the material rod carrier in an up-and-down extended state, and a transfer module for transferring the workpiece to the top of the material rod carrier and releasing it so that the workpiece is threaded onto the material rod carrier. The threading unit also includes a support component for supporting the workpiece that has been threaded onto the material rod carrier, and a lifting drive component for driving the support component to move up and down.

[0006] As a further improvement to the above technical solution: The holding component is configured to switch between a holding state that holds the workpiece and a non-holding state that does not hold the workpiece.

[0007] The holding assembly includes a holding member and a position switching assembly for driving the holding member to switch between a holding state and a non-holding state. The holding member has two holding portions, and a U-shaped groove is formed between the two holding portions. When the holding member is in the holding state, the material rod carrier is located in the U-shaped groove. When the holding member is in the non-holding state, the material rod carrier exits the U-shaped groove.

[0008] The position conversion component includes a translation drive component disposed at the drive end of the lifting drive component. The support member is connected to the drive end of the translation drive component. The translation drive component drives the support member to reciprocate linearly so that the material rod carrier enters the U-shaped groove or exits the U-shaped groove.

[0009] Both the lifting drive component and the translation drive component are linear modules or telescopic cylinders.

[0010] The rod-through unit is also provided with an upper fixing assembly for fixing the upper part of the rod carrier. The upper fixing assembly includes two clamping mechanisms that can clamp and release the rod carrier. When clamping the rod carrier, the clamping mechanism can support the workpiece passing through the rod carrier. When releasing the rod carrier, the clamping mechanism allows the workpiece passing through the rod carrier to pass through. The two clamping mechanisms are arranged vertically and horizontally to form a space that can accommodate at least one workpiece.

[0011] The two clamping mechanisms operate in a cyclical sequence according to the following preset steps: S1: Both the upper and lower clamping mechanisms are in the state of releasing the material rod carrier; S2: The upper clamping mechanism switches to the state of clamping the material bar carrier, while the lower clamping mechanism remains in the state of releasing the material bar carrier; S3: Both the upper and lower clamping mechanisms are switched to the state of clamping the material bar carrier; S4: The upper clamping mechanism switches to the state of releasing the material bar carrier, while the lower clamping mechanism remains in the state of clamping the material bar carrier.

[0012] The clamping mechanism includes a sliding block and two clamping fingers. The two clamping fingers are arranged in a reciprocating linear sliding manner and can clamp the material rod carrier by sliding towards each other or moving away from each other to release the material rod carrier. The sliding block is arranged in a reciprocating linear sliding manner, and each clamping finger is connected to the sliding block by a connecting rod. When the sliding block reciprocates linearly, it drives the two clamping fingers to move towards each other or away from each other through the connecting rod. The clamping mechanism also includes an elastic element that elastically forces the two clamping fingers to move towards each other and a driving mechanism for driving the sliding block to slide to overcome the effect of the elastic element and make the two clamping fingers move away from each other.

[0013] The drive mechanism includes a roller and a cam driven to rotate by a drive member. The roller is mounted on the sliding block. The cam has a cam surface that abuts against the roller and, when the cam rotates, cooperates with an elastic member to drive two gripper fingers to clamp and release the material rod carrier.

[0014] The cams of the two clamping mechanisms are mounted on the same rotating shaft and driven to rotate synchronously by the same drive unit connected to the rotating shaft. The cam surfaces of the cams of the two clamping mechanisms are configured to cause the two clamping mechanisms to cycle in sequence according to the preset steps.

[0015] The transfer module includes a first gripper mechanism for clamping and placing workpieces and a robotic arm for driving the first gripper mechanism.

[0016] The transfer module also includes a flipping component, which is used to receive the workpiece sent by the first gripper mechanism, flip the workpiece 180° and transfer it to the top of the bar carrier and release it so that the workpiece can be passed onto the bar carrier.

[0017] The flipping assembly includes a second gripper mechanism for clamping and holding a workpiece, a flipping seat rotatably mounted around a preset axis, and a flipping drive mechanism for driving the flipping seat to flip around the preset axis. The second gripper mechanism is mounted on the flipping seat and can be flipped 180° by the flipping seat.

[0018] The cemented carbide product rod insertion device has two rod insertion units, and the two rod insertion units share a transfer module. The transfer module includes two first gripper mechanisms driven by the same robot arm, and two second gripper mechanisms are installed on the flipping seat of the flipping component of the transfer module.

[0019] The lower fixing assembly includes a support seat for supporting the lower end of the material rod carrier and a clamping mechanism for clamping and fixing the lower part of the material rod carrier.

[0020] Compared with the prior art, the advantages of the present invention are as follows: The carbide product threading device of the present invention, by adding a supporting component and a lifting drive component, allows the supporting component to support the workpiece already threaded on the material rod carrier from below when the transfer module releases a new workpiece. The supporting component moves downward synchronously with the lifting drive component, significantly shortening the falling distance between the new workpiece and the supported workpiece below, even approaching zero. This solves the problem of "large direct drop distance and easy collision damage" in traditional equipment. Simultaneously, after supporting the workpiece, the supporting component provides intermediate dynamic support for the material rod carrier, suppressing the swaying of the material rod carrier during the threading process to a certain extent, thus improving the accuracy and stability of the threading operation.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 4 As shown, the cemented carbide product rod insertion device of this embodiment includes one or more rod insertion units. The rod insertion unit includes a lower fixing component 1 for fixing the lower part of the rod carrier 100 and keeping the rod carrier 100 in an up-and-down extended state, and a transfer module 2 for transferring the workpiece 200 to the top of the rod carrier 100 and releasing it so that the workpiece 200 is inserted into the rod carrier 100. The rod insertion unit also includes a support component 3 for supporting the workpiece 200 that has been inserted into the rod carrier 100, and a lifting drive component 4 for driving the support component 3 to move up and down.

[0033] This cemented carbide product threading device, by adding a supporting component 3 and a lifting drive component 4, allows the supporting component 3 to support the workpiece 200 already threaded onto the material rod carrier 100 from below when the transfer module 2 releases a new workpiece 200. Simultaneously, the supporting component 3 moves downwards in sync with the lifting drive component 4, significantly shortening the falling distance between the new workpiece 200 and the supported workpiece 200 below, even approaching zero. This solves the problem of "large direct drop distance and easy collision damage" in traditional equipment. Simultaneously, after supporting the workpiece 200, the supporting component 3 provides intermediate dynamic support for the material rod carrier 100, suppressing the swaying of the material rod carrier 100 during the threading process and improving the accuracy and stability of the threading operation.

[0034] In this embodiment, the holding component 3 is configured to switch between a holding state for the workpiece 200 and a non-holding state for not holding the workpiece 200. Thus, the holding component 3 can flexibly switch between a working state and a standby state. When a new workpiece 200 needs to be received, it switches to the holding state to ensure a buffer for receiving the workpiece; when the rod insertion operation is completed or the material rod carrier 100 needs to be removed, it switches to the non-holding state, avoiding interference with the normal loading and unloading of the material rod carrier 100, thereby improving the operational flexibility and automation level of the equipment.

[0035] In this embodiment, as Figure 5 As shown, the support assembly 3 includes a support member 31 and a position switching assembly 32 for driving the support member 31 to switch between a support state and a non-support state. The support member 31 has two support portions 311, and a U-shaped groove 312 is formed between the two support portions 311. When the support member 31 is in the support state, the material rod carrier 100 is located in the U-shaped groove 312. When the support member 31 is in the non-support state, the material rod carrier 100 is removed from the U-shaped groove 312. The support member 31 adopts a U-shaped structure, which has the advantages of simple structure and reliable positioning. In the holding state, the material rod carrier 100 is housed in the U-shaped groove 312, and the two holding parts 311 support the lower end face of the workpiece 200 from both sides, which can stably support the workpiece 200 and prevent the workpiece 200 from tilting or falling off during the lifting process. In the non-holding state, the holding state can be quickly released by simply driving the holding part 31 to move it so that the material rod carrier 100 can exit from the U-shaped opening side, achieving a smooth and fast switch without impacting the material rod carrier 100.

[0036] In this embodiment, the position conversion component 32 includes a translation drive component 321 disposed at the drive end of the lifting drive component 4. The supporting member 31 is connected to the drive end of the translation drive component 321. The translation drive component 321 drives the supporting member 31 to reciprocate linearly, so that the material rod carrier 100 enters or exits the U-shaped groove 312. This composite drive structure of "lifting + translation" allows the supporting member 31 to move up and down with the lifting drive component 4 to adjust the supporting height, and it can also move horizontally independently to cut into and out of the material rod carrier 100. The two motion dimensions are independent of each other and do not interfere with each other. The control logic is simple and clear, and it can accurately control the position and timing of the supporting member 31, ensuring the accuracy and reliability of the rod threading process.

[0037] In this embodiment, both the lifting drive assembly 4 and the translation drive assembly 321 are double-rod cylinders, which have the advantages of high standardization, convenient control, and simple maintenance. This helps to reduce the manufacturing and maintenance costs of the equipment and improve its reliability and service life. In other embodiments, the lifting drive assembly 4 and the translation drive assembly 321 may also adopt linear modules or other existing technologies that can realize linear reciprocating drive, such as telescopic cylinders, electric push rods, or combinations of motors and lead screw mechanisms.

[0038] In this embodiment, as Figures 2 to 4 , Figures 6 to 8As shown, the rod-through unit is also provided with an upper fixing component 5 for fixing the upper part of the rod carrier 100. The upper fixing component 5 includes two clamping mechanisms 51 that can clamp and release the rod carrier 100. When clamping the rod carrier 100, the clamping mechanism 51 can support the workpiece 200 passing through the rod carrier 100. When releasing the rod carrier 100, the clamping mechanism 51 allows the workpiece 200 passing through the rod carrier 100 to pass through. The two clamping mechanisms 51 are arranged vertically and horizontally to form a space that can accommodate at least one workpiece 200. The two clamping mechanisms 51 of the upper fixing component 5 can alternately operate to control the lowering of the workpiece 200, ensuring that there is always one clamping mechanism 51 clamping and fixing the upper part of the material rod carrier 100 during the rod insertion process. This ensures that the material rod carrier 100 is effectively supported at both the upper and lower ends, thereby significantly improving the overall rigidity and stability of the material rod carrier 100. It also ensures that the upper part of the material rod carrier 100 is always in a precise predetermined position, thus ensuring that the transfer module 2 can accurately align with the material rod carrier 100 to release the rod insertion, effectively solving the problem of "the upper part of the material rod shaking, causing it to be unable to be aligned".

[0039] In this embodiment, the two clamping mechanisms 51 operate in a cyclical sequence according to the following preset steps: S1: Both the upper clamping mechanism 51 and the lower clamping mechanism 51 are in the state of releasing the bar carrier 100; in this state, the bar carrier 100 can freely enter or exit the two clamping mechanisms 51, which is convenient for loading a new bar carrier 100 or unloading the bar carrier 100 with the workpiece 200 inserted.

[0040] S2: The upper clamping mechanism 51 switches to the state of clamping the material rod carrier 100, while the lower clamping mechanism 51 remains in the state of releasing the material rod carrier 100. In this state, the material rod carrier 100 is clamped by the upper clamping mechanism 51, which can release the workpiece 200 for rod insertion, and the workpiece 200 is supported by the upper clamping mechanism 51.

[0041] S3: Both the upper clamping mechanism 51 and the lower clamping mechanism 51 are switched to the state of clamping the material rod carrier 100; in this state, the material rod carrier 100 is clamped by the two clamping mechanisms 51 at the same time, in preparation for the upper clamping mechanism 51 to release the material rod carrier 100.

[0042] S4: The upper clamping mechanism 51 switches to the state of releasing the material rod carrier 100, while the lower clamping mechanism 51 remains in the state of clamping the material rod carrier 100. In this state, the material rod carrier 100 is held in place by the lower clamping mechanism 51, and the workpiece 200, which was originally held by the upper clamping mechanism 51, falls onto the lower clamping mechanism 51.

[0043] After returning to step S1 from step S4, the workpiece 200 held by the lower clamping mechanism 51 falls onto the support assembly 3; then, in step S2, the material rod carrier 100 is clamped again by the upper clamping mechanism 51. This cycle repeats, ensuring that there is always a clamping mechanism 51 clamping and fixing the upper part of the material rod carrier 100 during the process of each workpiece 200 being threaded through the rod.

[0044] The above-mentioned cyclic action steps ensure that there is always a clamping mechanism 51 clamping and fixing the upper part of the material rod carrier 100 during the rod insertion process, which significantly improves the overall rigidity and stability of the material rod carrier 100 during the rod insertion process; at the same time, it also takes into account the convenience of loading and unloading the material rod carrier 100, and its action process is simple and easy to control.

[0045] In this embodiment, the clamping mechanism 51 includes a sliding block 512 and two clamping fingers 511. The two clamping fingers 511 are arranged in a reciprocating linear sliding manner and can clamp the material rod carrier 100 by sliding towards each other or by moving away from each other. The sliding block 512 is arranged in a reciprocating linear sliding manner. Each clamping finger 511 is connected to the sliding block 512 by a connecting rod 513. The two ends of the connecting rod 513 are respectively hinged to the sliding block 512 and the clamping fingers 511. When the sliding block 512 reciprocates linearly, it drives the two clamping fingers 511 to move towards each other or away from each other through the connecting rod 513. The clamping mechanism 51 also includes an elastic element (not shown in the figure) that elastically forces the two clamping fingers 511 to move towards each other and a driving mechanism for driving the sliding block 512 to slide to overcome the action of the elastic element and make the two clamping fingers 511 move away from each other. The clamping mechanism 51 adopts a mechanical structure of "connecting rod 513 + sliding block 512 + elastic reset" to achieve the synchronous opening and closing of the clamping fingers 511. The elastic element provides a normally closed clamping force to ensure that the clamping fingers 511 can maintain a clamped state when there is no power input, and has a fail-safe protection function (it can still clamp when the power is off to prevent the workpiece 200 from falling accidentally). When the drive mechanism pushes the sliding block 512, the clamping fingers 511 are opened through the connecting rod 513, releasing the material rod carrier 100. This purely mechanical transmission method has a compact structure, reliable operation, and rapid response. Compared with pneumatic grippers and other solutions, it has the advantages of low cost, long service life, and no impact from air pressure fluctuations, and is particularly suitable for long-term operation in environments with high stability requirements, such as around coating equipment. The above-mentioned elastic element is a telescopic spring, connected between the connecting rod 513 connecting the two clamping fingers 511. In other embodiments, the telescopic spring can also be connected between the two clamping fingers 511, or directly connected to the sliding block 512.

[0046] In this embodiment, the driving mechanism includes a roller 515 and a cam 516 driven to rotate by a driving member. The roller 515 is mounted on a sliding block 512. The cam 516 has a cam surface 5161, which abuts against the roller 515 and, when the cam 516 rotates, cooperates with an elastic element to drive the two gripper fingers 511 to clamp and release the material rod carrier 100. The "cam 516 + roller 515" driving method converts rotational motion into linear reciprocating motion of the sliding block 512. The cam mechanism has the advantage of designable motion laws; by designing the cam profile curve, the opening and closing timing, speed, and holding time of the gripper fingers 511 can be precisely controlled. The roller 515 can convert sliding friction into rolling friction, significantly reducing transmission resistance and wear, and improving the smoothness and service life of the mechanism. The cam 516 and the elastic element form a "force-closed" system, ensuring that the roller 515 is always in contact with the cam surface 5161, ensuring accurate transmission without backlash, and making the clamping action more precise and reliable.

[0047] In this embodiment, the cams 516 of the two clamping mechanisms 51 are mounted on the same rotating shaft and driven synchronously by the same drive unit connected to the shaft. The cam surfaces 5161 of the cams 516 of the two clamping mechanisms 51 are configured to cause the two clamping mechanisms 51 to cycle and operate in a preset sequence. By driving the two cams 516 simultaneously with a single drive unit, the timing coordination of the two clamping mechanisms 51 is achieved using the different profile curves (phase difference) of the two cams 516. This allows for automatic completion of the relay action without the need for a complex electronic control system and multiple independent drive sources. This purely mechanical timing control method greatly simplifies the complexity of the control system, reduces manufacturing costs, and improves the synchronization and reliability of the actions, avoiding signal delays or program errors that may occur in electronic control. The combination of the drive unit motor and the pulley transmission mechanism is described above, with the motor connected to the rotating shaft of the cam 516 via the pulley transmission mechanism.

[0048] In other embodiments, the clamping mechanism 51 may also adopt other existing structural forms, such as two pneumatic or electric grippers, whose actions and timing are controlled by a control program.

[0049] In this embodiment, as Figure 1 As shown, the transfer module 2 includes a first gripper mechanism 21 for clamping and placing the workpiece 200 and a robotic arm 22 for driving the first gripper mechanism 21. The combination of the first gripper mechanism 21 and the robotic arm 22 can flexibly grasp the workpiece 200 and complete the rod-passing action, featuring flexible movement and precise positioning. The first gripper mechanism 21 can be a commercially available electric or pneumatic three-finger gripper, or other existing gripper mechanisms capable of clamping and releasing the workpiece 200; the robotic arm 22 can be an XYZ three-axis linear slide module capable of linear motion in three-dimensional space, or other existing multi-degree-of-freedom robotic arms.

[0050] In this embodiment, as Figures 2 to 4 , Figure 9 As shown, the transfer module 2 also includes a flipping component 23, which receives the workpiece 200 fed by the first gripper mechanism 21, flips the workpiece 200 180°, transfers it above the material bar carrier 100, and releases it so that the workpiece 200 passes onto the material bar carrier 100. The flipping component 23 in the receiving state can be seen in [reference needed]. Figure 2 and Figure 4 When the flipping component 23 is in the rod-through state, please refer to Figure 3 The addition of the flipping component 23 solves the process challenges of directional requirements for certain products. Some cemented carbide products (such as cutting tools and drill bits) may have a distinct front and back, or require a specific orientation when inserted into the feed bar according to coating process requirements. The flipping component 23 can flip the workpiece 200 delivered by the first gripper mechanism 21 by 180°, ensuring that the workpiece 200 is inserted into the feed bar carrier 100 in the correct orientation, avoiding the hassle of manual intervention to adjust the orientation. This design expands the applicability of the equipment, enabling it to adapt to feed bar operations for more types of products with more complex process requirements, and improving the equipment's versatility and automation level.

[0051] In this embodiment, the flipping assembly 23 includes a second gripper mechanism 231 for holding the workpiece 200, a flipping seat 232 rotatably mounted around a preset axis, and a flipping drive mechanism 233 for driving the flipping seat 232 to flip around the preset axis. The second gripper mechanism 231 is mounted on the flipping seat 232 and can be flipped 180° by the flipping seat 232. This flipping assembly 23 has a simple structure, reliable operation, and is easy to control. After the second gripper mechanism 231 receives the workpiece 200, it clamps it. The flipping drive mechanism 233 drives the flipping seat 232 to rotate the second gripper mechanism 231 as a whole by 180°, completing the posture adjustment of the workpiece 200. The flipping action is performed around the preset axis, ensuring the positional accuracy of the workpiece 200 after flipping, which facilitates the subsequent release of the alignment rod carrier 100. The second gripper mechanism 231 can be a commercially available electric or pneumatic three-finger gripper, or other existing gripper mechanisms capable of clamping and releasing the workpiece 200; the flipping drive mechanism 233 can be a motor.

[0052] In this embodiment, the cemented carbide product rod threading device has two rod threading units, and the two rod threading units share a transfer module 2. The transfer module 2 includes two first gripper mechanisms 21 driven by the same robot arm 22, and two second gripper mechanisms 231 are installed on the flipping seat 232 of the flipping component 23 of the transfer module 2. This solution realizes parallel operation of two stations, with the two rod threading units sharing a transfer module 2, doubling the production capacity within a limited equipment space. The two first gripper mechanisms 21 driven by the same robot arm 22, and the two second gripper mechanisms 231 integrated on the flipping seat 232, form a highly integrated dual-station collaborative operation system. This layout can significantly increase the number of rods threaded per unit time while ensuring rod threading accuracy, thus improving rod threading efficiency. It is especially suitable for mass production scenarios and has significant cost reduction and efficiency improvement effects. In other embodiments, the number of rod threading units in the cemented carbide product rod threading device can also be one or more, which can be reasonably selected and set according to needs. When there are two or more rod threading units, the transfer module 2 of each rod threading unit can also be set separately.

[0053] In this embodiment, the lower fixing component 1 includes a support seat for supporting the lower end of the material rod carrier 100 and a clamping mechanism 11 for clamping and fixing the lower part of the material rod carrier 100. The lower fixing component 1 adopts a dual fixing method of "support + clamping", providing a stable and reliable bottom fixation for the material rod carrier 100. The support seat bears the entire weight of the material rod carrier 100 and the inserted workpiece 200, preventing the lower end of the material rod from being suspended in the air; the clamping mechanism 11 radially clamps the lower part of the material rod carrier 100 to prevent the material rod carrier 100 from swinging or displacing when subjected to external forces. The structure of the support seat is not particularly limited, as long as it can support the material rod carrier 100. For example, it can be an automatic feeding device used in the rod insertion equipment for cemented carbide products (e.g., a linear conveyor mechanism, a rotary conveyor mechanism, etc.). The clamping mechanism 11 can be a commercially available electric or pneumatic two-finger gripper, or other existing clamping mechanisms capable of clamping and releasing the workpiece 200. In other embodiments, the lower fixing component 1 can also be in any structural form, as long as it has the function of fixing and releasing the material rod carrier 100.

[0054] The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the inventive concept should also be considered within the scope of protection of the present invention.
