Description

Technical Field

[0001] The embodiments of this utility model relate to the field of mold processing equipment technology, specifically, to a glass mold processing device. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of small amounts of auxiliary materials. Besides its applications in construction for wind insulation and light transmission, glass is widely used in the production of tableware, such as glass bottles, glass jars, and fish tanks. Most glassware requires the use of molds in its production, and pre-set patterns can be added to the molds to enhance the aesthetic appeal of the tableware's exterior.

[0003] In reality, most glassware has a circular or near-circular cross-section, while a minority has a polygonal or irregular cross-section. The molds used in glassware production are generally square or imitate the shape of the product, and usually consist of a pair of opposing half-molds. The mold can be used to obtain a rough blank through casting, and then the cavity of the rough blank can be rough-machined and fine-machined to obtain an aesthetically pleasing glass mold, which is then used to make glassware.

[0004] Glass molds are mostly made of metal, which is durable. The mold itself is not light. When processing the mold, it is time-consuming, labor-intensive and inefficient to manually move the mold on and off the machine tool. Therefore, it is necessary to use mechanical external force to complete the loading and unloading of the mold blank. At the same time, it is inevitable that debris will remain in the mold cavity during the mold processing. Therefore, it is necessary to clean the debris to avoid affecting subsequent processing. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a glass mold processing device, which solves the problem in the related art that residual debris in the mold cavity during the glass mold processing will affect subsequent processing.

[0006] According to one aspect, at least one embodiment of the present invention provides a glass mold processing apparatus, comprising: The worktable is used to support the workpiece; A machining robotic arm is mounted above a worktable and is used to process workpieces. The transfer arm is located on one side of the worktable. The transfer arm can transfer workpieces onto the worktable or remove workpieces from the worktable. The hanger is rotatably mounted on the transfer arm. The hanger is equipped with two jaws for holding the workpiece. The hanger is configured to drive the workpiece held by the jaws to rotate so that the mold cavity of the workpiece faces the horizontal direction. An air blowing pipe, located on the transfer arm above the hanger, is configured to output airflow to blow the mold cavity of the workpiece that rotates synchronously with the hanger.

[0007] For example, in a glass mold processing device provided in at least one embodiment of this utility model, two grippers are symmetrically distributed on the hanger, and the grippers include: The hoisting section is slidably mounted on the hoisting frame; The transition section is located on the hoisting section. The extension direction of the transition section is set at an angle to the extension direction of the hoisting section. The transition section is configured to abut against the upper end surface of the workpiece. The side pressure section is located at the end of the transition section away from the hoisting section, and is configured to abut against the side of the workpiece.

[0008] For example, in a glass mold processing device provided in at least one embodiment of the present invention, the side pressing section has an inclined surface at one end near the transition section, and the side of the transition section that abuts against the upper end surface of the workpiece forms a clamping angle A with the inclined surface, where 70° < A < 90°.

[0009] For example, in at least one embodiment of the glass mold processing device provided by this utility model, an auxiliary clamping unit is further included, the auxiliary clamping unit comprising: A sliding pin extends through the side pressure section along the direction of the side pressure section and is slidably disposed on the side pressure section; A pressure pin is slidably mounted on a sliding pin. The pressure pin is configured to slide close to and press against the outer peripheral surface of the workpiece.

[0010] For example, in a glass mold processing device provided in at least one embodiment of this utility model, the auxiliary clamping unit further includes: The oscillating head is mounted on the pressure pin and is configured to press against the outer circumferential surface of the workpiece under the sliding action of the pressure pin.

[0011] For example, in a glass mold processing device provided in at least one embodiment of this utility model, the auxiliary clamping unit further includes: The tension elastic element acts on the pressure pin at one end and on the sliding pin at the other end. The tension elastic element is configured to act on the swing head and enable the swing head to approach the outer peripheral surface of the workpiece.

[0012] For example, in a glass mold processing device provided in at least one embodiment of this utility model, the auxiliary clamping unit further includes: A compression elastic element is provided, with one end acting on the overlap of the side pressure section and the transition section, and the other end acting on the sliding pin. The compression elastic element is configured to act on the sliding pin and enable the sliding pin to approach the hanger.

[0013] For example, in at least one embodiment of the glass mold processing apparatus provided by this utility model, a transmission unit is further included, the transmission unit comprising: A two-way threaded rod, with each end threadedly connected to two lifting sections; A guide rod is mounted on the hanger and slidably connected to the two lifting sections. The axis of the guide rod is parallel to the axis of the double-threaded rod. A rotary actuator, mounted on a hanger, is used to provide the driving force for the rotation of a bidirectional threaded rod; The bevel gear pair is connected to a bidirectional threaded rod at one end and to a rotary drive at the other end.

[0014] For example, in a glass mold processing device provided in at least one embodiment of the present invention, the air blowing pipe has a plurality of air outlets that are linearly and spaced apart.

[0015] For example, in a glass mold processing device provided in at least one embodiment of the present invention, the air blowing pipe and the conveying arm are rotatably connected, and the air blowing pipe has a number of exhaust holes distributed along the axis of the air blowing pipe, each group of exhaust holes including a number of exhaust holes distributed around the outer periphery of the air blowing pipe.

[0016] The beneficial effects of the embodiments of this utility model are as follows: In this invention, the worktable provides a stable machining reference surface for the glass mold blank, ensuring the blank's position is fixed during processing and providing a foundation for the precise operation of the machining robot arm. The machining robot arm can automate the machining of the blank, replacing manual operation and improving processing efficiency and accuracy. The transfer arm enables automatic transfer of the blank between the storage area and the worktable, solving the problem of time-consuming and labor-intensive manual mold handling and further improving overall processing efficiency. The cooperation between the hanger and the gripper not only stably holds the blank but also allows for adjustment of the blank's posture by rotation, turning the mold cavity opening to a horizontal direction. In this posture, debris inside the mold cavity is more likely to accumulate at the opening under gravity, facilitating cleaning. The air pipe blows through the mold cavity during the blank's rotation, and the airflow acts comprehensively along the circumference of the mold cavity's inner wall, blowing out residual debris from the horizontal opening, effectively removing debris from the mold cavity and preventing it from scratching the mold surface or affecting dimensional accuracy during subsequent processing. The coordinated operation of the transfer arm, hanger, and air blowing pipe allows the transfer of the preform and the cleaning of the mold cavity to be carried out simultaneously, eliminating the need for additional cleaning procedures, shortening the processing cycle, ensuring the stability of the cleaning effect, ensuring that subsequent processing is not affected by debris, and ultimately improving the processing quality of the glass mold.

[0025] like Figures 1-2 and Figures 6-8As shown, this invention illustrates a glass mold processing apparatus according to one embodiment of the present invention. The apparatus includes a worktable 10, a processing robotic arm 11, a transfer arm 12, a hanger 30, and an air blowing pipe 50. The worktable 10 is horizontally positioned, and its surface is used to place the glass mold blank to be processed. The base (not shown) of the processing robotic arm 11 is fixed to the ground on one side of the worktable 10. The actuator of the robotic arm extends above the worktable 10, and can be equipped with processing tools such as milling cutters and grinding wheels for cutting, grinding, and other processing operations on the blank on the worktable 10. The fixed end of the transfer arm 12 is installed on the side of the worktable 10 away from the base of the processing robotic arm 11. The movable end of the transfer arm 12 can move horizontally and vertically, and its range of movement covers the area above the worktable 10 and the blank storage area.

[0026] The hanger 30 is rotatably connected to the movable end of the transfer arm 12 via a rotating shaft. The axis of the rotating shaft extends horizontally. The main body of the hanger 30 is plate-shaped / rod-shaped. The grippers 40 are installed on the downward-facing side of the hanger 30, and the two grippers 40 are used to grasp and release the blank. One end of the air blowing pipe 50 is installed at the movable end of the transfer arm 12, located above the hanger 30. The air inlet of the air blowing pipe 50 is connected to an external air source through a pipeline.

[0027] During operation, the movable end of the transfer arm 12 moves to the blank storage area, and the gripper 40 on the hanger 30 closes to hold the blank. The transfer arm 12 moves the blank above the worktable 10 and places it on the table, then the transfer arm 12 retracts. The machining arm 11 starts to process the blank on the worktable 10. After processing, the movable end of the transfer arm 12 moves back above the worktable 10, and the gripper 40 re-grips the blank and lifts it off the worktable 10. At this time, the hanger 30 rotates around the pivot, causing the blank to rotate synchronously, so that the opening of the blank's mold cavity 21 gradually turns to the horizontal direction. At the same time, an external air source supplies air to the air blowing pipe 50, and the airflow output from the air blowing pipe 50 blows into the horizontally oriented mold cavity 21. As the hanger 30 continues to rotate, the mold cavity 21 of the blank is aligned with the air outlet direction of the air blowing pipe 50 along the circumference, and the airflow thoroughly blows the inner wall of the mold cavity 21. After purging, the hanger 30 rotates in the opposite direction to restore the billet to its initial position, the transfer arm 12 transfers the billet to the designated storage position, and the gripper 40 opens to release the billet.

[0028] The worktable 10 provides a stable machining reference surface for the glass mold blank, ensuring the blank's position is fixed during processing and providing a foundation for the precise operation of the machining robot arm 11. The machining robot arm 11 can automate the machining of the blank, replacing manual operation and improving machining efficiency and accuracy. The transfer arm 12 enables automatic transfer of the blank between the storage area and the worktable 10, solving the problem of time-consuming and labor-intensive manual mold handling and further improving overall machining efficiency. The cooperation between the hanger 30 and the gripper 40 not only stably holds the blank but also allows the blank's posture to be adjusted by rotation, turning the opening of the mold cavity 21 to a horizontal direction. In this posture, debris inside the mold cavity 21 is more likely to accumulate at the opening under gravity, making it easier to clean. The air pipe 50 blows through the mold cavity 21 during the blank's rotation. The airflow can act circumferentially along the inner wall of the mold cavity 21, blowing out residual debris from the horizontal opening, effectively removing debris from the mold cavity 21 and preventing debris from scratching the mold surface or affecting the machining dimensional accuracy during subsequent processing. The coordinated operation of the transfer arm 12, the hanger 30, and the air blowing pipe 50 allows the transfer of the blank and the cleaning process of the mold cavity 21 to be carried out simultaneously, eliminating the need for additional cleaning procedures, shortening the processing cycle, ensuring the stability of the cleaning effect, ensuring that subsequent processing is not affected by debris, and ultimately improving the processing quality of the glass mold.

[0029] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 1-6 and Figure 8 As shown, the two grippers 40 are symmetrically distributed about the central axis of the hanger 30. The lifting section 41 of the gripper 40 is plate-shaped / rod-shaped and is slidably mounted on the lower end face of the hanger 30 along its length. The sliding direction of the lifting section 41 is parallel to the length extension direction of the hanger 30. The transition section 42 is fixed to the end of the lifting section 41 away from the lower end face of the hanger 30. The extension direction of the transition section 42 forms an angle with the extension direction of the lifting section 41. The side of the transition section 42 away from the hanger 30 is a plane for contacting the upper end face of the workpiece 20.

[0030] The side pressure section 43 is fixed to the end of the transition section 42 away from the hoisting section 41. The extension direction of the side pressure section 43 is set at an angle to the extension direction of the transition section 42. The side of the two side pressure sections 43 that are close to each other is used to contact the side of the workpiece 20.

[0031] When the transfer arm 12 moves the hanger 30 above the workpiece 20, the two lifting sections 41 slide along the hanger 30 in a direction away from each other, so that the distance between the two side pressing sections 43 is greater than the width of the mold. The hanger 30 moves downward, causing the lower surface of the transition section 42 to contact the upper end face of the workpiece 20. Then, the two lifting sections 41 slide along the hanger 30 towards each other, and the side-pressure section 43 gradually approaches and abuts against the two sides of the workpiece 20. The workpiece 20 is fixed by the pressure of the transition section 42 against the upper end face of the workpiece 20 and the clamping of the side sides by the side-pressure section 43. When it is necessary to release the workpiece 20, the two lifting sections 41 slide away from each other, the side-pressure section 43 disengages from the side sides of the workpiece 20, and the hanger 30 moves upward, causing the lower surface of the transition section 42 to disengage from the upper end face of the workpiece 20.

[0032] Two symmetrically distributed grippers 40 work together to clamp the workpiece 20, ensuring balanced force on the workpiece 20 and preventing tilting of the workpiece 20 due to force shift during clamping. The sliding fit between the lifting section 41 and the hanger 30 allows the spacing between the two grippers 40 to be adjusted, accommodating workpieces 20 of different sizes and improving the versatility of the device. The angle between the transition section 42 and the lifting section 41 allows the transition section 42 to naturally conform to the upper surface of the workpiece 20, forming a vertical constraint to ensure the consistency of the workpiece 20's conveying state and prevent the workpiece 20 from deflecting. The connection structure between the side pressure section 43 and the transition section 42 allows the side pressure section 43 to form a lateral constraint on the workpiece 20 from the horizontal direction. Together with the vertical constraint of the transition section 42, this forms a three-dimensional clamping space, ensuring that the workpiece 20 remains stable during rotation and transfer driven by the hanger 30, preventing shaking or falling off. The structural cooperation between the transition section 42 and the side pressure section 43 allows each part to undertake vertical and lateral constraint functions respectively, which facilitates the optimization of the structural parameters of each section according to the shape characteristics of the workpiece 20, enhances the adaptability and reliability of clamping, and provides a basic guarantee for the subsequent precise blowing of the mold cavity 21 by the air blowing pipe 50 and the stable processing of the processing robot arm 11.

[0033] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 2-5 As shown, considering that glass molds are generally modeled after the shape of a product, such as a beer bottle, where the outer wall of the product is arc-shaped, the outer shape of the mold is also generally arc-shaped.

[0034] The side pressing section 43 of the gripper 40 has a slope 44 at one end near the transition section 42. This slope 44 is located on the side where the two side pressing sections 43 are close to each other. The side of the transition section 42 that abuts against the upper end face of the workpiece 20 is a plane. This plane and the slope 44 of the side pressing section 43 form a clamping angle A, where 70° < A < 90°. When the gripper 40 clamps the workpiece 20, the plane of the transition section 42 is in contact with the upper end face of the workpiece 20, the slope 44 of the side pressing section 43 contacts the side edge of the workpiece 20, and the opening of the clamping angle A faces the corner of the workpiece 20 (where the two half molds are joined).

[0035] The inclined surfaces 44 of the two grippers 40 apply clamping forces from both sides of the workpiece 20 toward the center. The clamping force is decomposed along the inclined surface 44 into a component force pointing toward the upper end face of the workpiece 20 and a component force pointing toward the center of the workpiece 20. The component force pointing toward the upper end face of the workpiece 20 makes the transition section 42 fit more tightly against the upper end face of the workpiece 20, and the component force pointing toward the center of the workpiece 20 achieves lateral clamping of the workpiece 20.

[0036] The inclined surface 44 of the side pressure section 43 forms a clamping angle A of 70°~90° with the plane of the transition section 42. This allows the jaws 40 to contact the edges and corners of the workpiece 20 when clamping the workpiece 20. The clamping angle creates a vertical component of the clamping force. This component, combined with the pressure exerted by the transition section 42 on the upper surface of the workpiece 20, enhances the tightness of the fit between the transition section 42 and the upper surface of the workpiece 20, further preventing vertical displacement of the workpiece 20 during transfer or rotation. Simultaneously, the lateral component ensures that the workpiece 20 is stably clamped between the two jaws 40, preventing horizontal swaying. Compared to right-angle or obtuse-angle clamping structures, the clamping angle of 70°~90° allows the inclined surface 44 to better adapt to the contour of the corners of the workpiece 20. Especially for workpieces 20 with chamfers or arc transitions, it can reduce the gap during clamping, improve clamping stability, and provide a reliable clamping foundation for the hanger 30 to drive the workpiece 20 to rotate accurately and for the air pipe 50 to effectively blow the mold cavity 21.

[0037] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 1-3 , Figure 6 and Figure 8 As shown, in the auxiliary clamping unit 60 of the glass mold processing device, the sliding pin 61 is arranged along the extension direction of the side pressure section 43, passing through both ends of the side pressure section 43. The sliding pin 61 is clearance-fitted with the through hole of the side pressure section 43, and can slide relative to the side pressure section 43 along its own axis. The side pressure section 43 can be fixedly connected to the side pressure section 43 by means of fastening pins. The pressure pin 62 is arranged in a direction perpendicular to the sliding pin 61. One end of the pressure pin 62 is slidably connected to the end of the sliding pin 61 away from the transition section 42. The sliding direction is towards or away from the outer peripheral surface of the workpiece 20. The other end of the pressure pin 62 extends to the side of the side pressure section 43 facing the workpiece 20.

[0038] When the two jaws 40 approach each other, the pressure pin 62 first contacts the outer peripheral wall of the side of the workpiece 20 until the side pressing section 43 of the jaw 40 contacts the side of the workpiece 20; when it is necessary to release the workpiece 20, the two jaws 40 slide away from each other (the jaws 40 gradually move away from the workpiece 20), and the pressure pin 62 gradually separates from the outer peripheral wall of the side of the workpiece 20.

[0039] The sliding engagement between the sliding pin 61 and the side pressure section 43 provides a base for the pressure pin 62 to move closer to or further away from the workpiece 20, allowing the pressure pin 62 to adapt to the position of the outer peripheral surface of workpieces 20 of different sizes. During use, after adjusting the position of the sliding pin 61, it is fixed to the side pressure section 43 using fastening pins. The sliding connection between the pressure pin 62 and the sliding pin 61 allows the pressure pin 62 to independently adjust its contact distance with the outer peripheral surface of the workpiece 20, ensuring that, based on the clamping of the side pressure section 43, the pressure pin 62 can tightly press against the outer peripheral surface of the workpiece 20, forming additional radial constraint, enhancing the overall clamping stability, and preventing the workpiece 20 from rotating circumferentially or shifting radially during rotation or transfer driven by the hanger 30. The auxiliary clamping unit 60 complements the clamping function of the side pressure section 43 and the transition section 42. Especially for workpieces 20 with irregular outer peripheral surface shapes, the pressure pin 62 can slide to adapt to its surface contour, ensuring the reliability of clamping and providing further assurance for the precise blowing of the air pipe 50 into the mold cavity 21 and the stable operation of the processing robot arm 11.

[0040] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 2-3 and Figure 6 As shown, in the auxiliary clamping unit 60 of the glass mold processing device, the swing head 63 is oscillatingly connected to the end of the pressure pin 62 near the workpiece 20 via a pin shaft. The swing head 63 can rotate relative to the pressure pin 62 around the pin shaft. The side of the swing head 63 facing the workpiece 20 is a plane, used to contact the outer peripheral surface of the workpiece 20.

[0041] When the pressure pin 62 slides along the sliding pin 61 toward the workpiece 20, the swing head 63 first contacts the outer peripheral surface of the workpiece 20. As the pressure pin 62 continues to move, the swing head 63 rotates around the pin shaft under the reaction force of the outer peripheral surface of the workpiece 20 until the plane of the swing head 63 presses against the outer peripheral surface of the workpiece 20. When the pressure pin 62 slides along the sliding pin 61 away from the workpiece 20, the swing head 63 disengages from the outer peripheral surface of the workpiece 20 with the pressure pin 62 and rotates around the pin shaft to the initial position under its own gravity.

[0042] The oscillating connection between the oscillating head 63 and the pressure pin 62 allows the oscillating head 63 to adaptively adjust its posture according to the tilt angle or curved contour of the outer peripheral surface of the workpiece 20. This ensures that the oscillating head 63 forms a surface contact with the outer peripheral surface of the workpiece 20 rather than a point contact, increasing the contact area, reducing the pressure per unit area, and avoiding indentations or damage to the surface of the workpiece 20. The oscillating function of the oscillating head 63 allows the auxiliary clamping unit 60 to adapt to workpieces 20 with different outer peripheral surface shapes, including glass mold blanks with inclined surfaces 44, curved surfaces, or irregular surfaces, expanding the applicability of the device. At the same time, the formation of surface contact enhances the pressure stability of the oscillating head 63 on the workpiece 20. Combined with the sliding action of the pressure pin 62, this further restricts the displacement of the workpiece 20, ensuring that the workpiece 20 maintains a stable posture during the rotation driven by the hanger 30. This ensures that the air blowing pipe 50 can accurately align with the mold cavity 21 for blowing, improving the debris removal effect and providing a reliable guarantee for subsequent processing.

[0043] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 2-3 , Figure 6 and Figure 8 As shown, in the auxiliary clamping unit 60 of the glass mold processing device, the tension elastic element 64 is a conventional tension / compression spring from the prior art. The tension elastic element 64 is sleeved on the outer periphery of the pressure pin 62, with one end connected to the end of the pressure pin 62 away from the workpiece 20, and the other end connected to the end of the sliding pin 61 near the pressure pin 62. When the pressure pin 62 slides along the sliding pin 61 towards the workpiece 20, the tension elastic element 64 is stretched and generates elastic tension. The tension elastic element 64 is a conventional tension spring from the prior art.

[0044] When the swing head 63 moves towards and contacts the outer peripheral surface of the workpiece 20 along with the pressure pin 62, the tension of the elastic element 64 is transmitted to the swing head 63 through the pressure pin 62, causing the swing head 63 to press tightly against the outer peripheral surface of the workpiece 20. If there are uneven surfaces on the outer peripheral surface of the workpiece 20, when the swing head 63 swings around the pin shaft, the pressure pin 62 slides slightly along the sliding pin 61, and the deformation of the elastic element 64 is adjusted accordingly, always maintaining the elastic force on the swing head 63, ensuring that the swing head 63 and the outer peripheral surface of the workpiece 20 remain in continuous contact. When the workpiece 20 is released, the pressure pin 62 slides away from the workpiece 20 along the sliding pin 61 under the tension of the elastic element 64, causing the swing head 63 to detach from the workpiece 20.

[0045] The elastic force of the tension elastic element 64 provides a continuous and adjustable resistance force for the swing head 63, enabling the swing head 63 to adapt to changes in the shape of the outer circumference of the workpiece 20. Regardless of whether the surface of the workpiece 20 is flat, inclined, or curved, it can maintain stable contact and avoid local stress concentration or contact failure caused by rigid connection. The deformation adjustment capability of the tension elastic element 64 allows the pressure pin 62 and the swing head 63 to produce slight displacement, compensating for the dimensional error of the workpiece 20 or the deviation of the clamping position, and enhancing the fault tolerance of the auxiliary clamping unit 60. At the same time, the tension force ensures that the swing head 63 is always in close contact with the workpiece 20 during the rotation or transfer of the workpiece 20, further limiting the sway of the workpiece 20. Together with the clamping action of the side pressure section 43 and the transition section 42, it forms multiple constraints to ensure the stability of the workpiece 20's posture, providing a reliable guarantee for the precise blowing of the air pipe 50 into the mold cavity 21 and the high-precision operation of the processing robot arm 11.

[0046] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 2-3 As shown, in the auxiliary clamping unit 60 of the glass mold processing device, the compression elastic element 65 is a commonly used tension / compression spring in the prior art. The compression elastic element 65 is sleeved on the end of the sliding pin 61 near the transition section 42. One end of the compression elastic element 65 abuts against the overlap between the side pressure section 43 and the transition section 42, and the other end abuts against the end of the sliding pin 61 away from the pressure pin 62. When the mold size changes, the relative position between the sliding pin 61 and the side pressure section 43 can be adjusted, thereby adjusting the range of the sliding position of the pressure pin 62 against the workpiece 20, while the compression elastic element 65 is in a compressed state.

[0047] The elastic thrust of the compression elastic element 65 provides assistance for the sliding pin 61 on the side pressure section 43, making it easier for the sliding pin 61 to slide upward and adjust its position.

[0048] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figure 2 , Figure 6 and Figure 8As shown, in the transmission unit 70 of the glass mold processing device, a bidirectional threaded rod 71 is arranged along the length of the hanger 30, with both ends rotatably supported on the hanger 30 via bearing seats. The threads at both ends of the bidirectional threaded rod 71 have opposite directions. The ends of the two lifting sections 41 furthest from the transition section 42 are each provided with threaded holes, which are respectively engaged with the threads at both ends of the bidirectional threaded rod 71. A guide rod 72 is arranged parallel to the bidirectional threaded rod 71, with both ends fixed to the hanger 30. Each of the two lifting sections 41 has a through hole through which the guide rod 72 passes and slides in contact with the lifting section 41. A rotary actuator 73 is fixed at the middle position of the hanger 30, and its output shaft extends in a direction perpendicular to the bidirectional threaded rod 71. The rotary actuator 73 is a conventional electrically driven motor. The bevel gear pair 74 includes a driving bevel gear and a driven bevel gear. The driving bevel gear is fixed on the output shaft of the rotary drive 73, and the driven bevel gear is fixed at the middle position of the bidirectional threaded rod 71. The driving bevel gear meshes with the driven bevel gear.

[0049] When the rotary drive 73 is started, its output shaft drives the active bevel gear to rotate. The active bevel gear drives the driven bevel gear to rotate through meshing transmission, which in turn drives the bidirectional threaded rod 71 to rotate around its own axis. Since the threads at both ends of the bidirectional threaded rod 71 have opposite directions of rotation, and the lifting section 41 is restricted from circumferential rotation due to the sliding fit with the guide rod 72, the two lifting sections 41 move towards or away from each other along the guide rod 72 under the action of the threads, realizing the opening and closing action of the gripper 40.

[0050] The threaded engagement between the bidirectional threaded rod 71 and the two lifting sections 41 allows the rotation of a single threaded rod to drive the two lifting sections 41 to move synchronously in opposite directions, ensuring the coordination of the opening and closing actions of the gripper 40, ensuring balanced force on both sides of the workpiece 20, and preventing workpiece 20 from shifting during clamping. The sliding engagement between the guide rod 72 and the lifting section 41 provides guiding constraint for the lifting section 41, preventing it from rotating with the bidirectional threaded rod 71, ensuring stable linear movement, and improving the accuracy of the clamping position. The rotary actuator 73 transmits power to the bidirectional threaded rod 71 through the bevel gear pair 74, achieving a vertical conversion of the transmission direction. This allows the actuator to be installed on the hanger 30 in a reasonable spatial layout, saving installation space and avoiding interference with other components. The transmission structure of the bevel gear pair 74 has high transmission efficiency and stability, ensuring reliable transmission of driving torque, enabling the gripper 40 to stably clamp workpieces 20 of different weights. The entire transmission unit 70 achieves automated control of the opening and closing of the gripper 40 through mechanical linkage, replacing manual operation, improving clamping efficiency and accuracy. In coordination with the transfer arm 12, hanger 30 and other structures, it ensures the stability of blank transfer and clamping during glass mold processing, laying the foundation for subsequent processing and cleaning processes.

[0051] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 1-2 , Figure 6 and Figure 8 As shown, the air blowing pipe 50 of the glass mold processing device is long and rod-shaped, with several air outlets 51 on its side wall along its length. The air outlets 51 are linearly arranged along the axis of the air blowing pipe 50, and the distance between two adjacent air outlets 51 is equal. Each air outlet 51 is a through hole penetrating the wall of the air blowing pipe 50, and the axis of the through hole is perpendicular to the axis of the air blowing pipe 50. All air outlets 51 open in the same direction, facing the mold cavity 21 of the workpiece 20 held by the hanger 30. One end of the air blowing pipe 50 is closed, and the other end is connected to the air supply pipeline of an external air source. The high-pressure gas supplied by the air source is ejected from each air outlet 51 through the internal channel of the air blowing pipe 50, forming multiple parallel airflows.

[0052] When the hanger 30 rotates the workpiece 20 to make the mold cavity 21 face horizontally, the axis of the air blowing pipe 50 is parallel to the axis of the workpiece 20 and the mold cavity 21, and each air outlet 51 corresponds to a different axial position on the inner wall of the mold cavity 21. After the high-pressure gas is ejected from the air outlet 51, it blows along the axis of the mold cavity 21 towards the inner wall. The air outlets 51 located at different positions on the air blowing pipe 50 act on different axial areas of the mold cavity 21, achieving a complete coverage and blowing of the inner wall of the mold cavity 21.

[0053] Several linearly spaced air outlets 51 enable the air blowing pipe 50 to simultaneously output multiple airflows. Each airflow acts on a different axial position on the inner wall of the mold cavity 21, avoiding cleaning dead zones caused by the limited cleaning range of a single airflow and ensuring that debris in all areas of the inner wall of the mold cavity 21 is effectively blown away. The spaced distribution of the air outlets 51 creates a uniform blowing coverage within the mold cavity 21, preventing excessive concentration of local airflow that could damage the inner wall of the mold cavity 21, while ensuring balanced blowing force in each area and improving the thoroughness of debris removal. The multi-outlet structure enhances the adaptability of the air blowing pipe 50 to the mold cavity 21. Regardless of the length / width variation of the mold cavity 21, the distribution of the air outlets 51 can cover its axial range. Combined with the rotation of the workpiece 20 driven by the hanger 30, comprehensive blowing of the circumferential and axial directions of the mold cavity 21 is achieved, effectively removing residual processing debris, avoiding interference with subsequent processing, and further improving the processing quality of the glass mold.

[0054] In some examples, the structure of the glass mold processing device is detailed, for example, such as Figures 1-2 and Figure 8As shown, the air blowing pipe 50 of the glass mold processing device is connected to the movable end of the transfer arm 12 via a rotating shaft. The axis of the rotating shaft extends horizontally and is perpendicular to the axis of the air blowing pipe 50. A bushing is provided at one end of the air blowing pipe 50 near the transfer arm 12. The bushing is fitted around the outer circumference of the rotating shaft and has a clearance fit, allowing the air blowing pipe 50 to rotate relative to the transfer arm 12 around the axis of the rotating shaft. Several sets of exhaust holes 52 are provided on the wall of the air blowing pipe 50, with each set of exhaust holes 52 spaced apart along the axial direction of the air blowing pipe 50. Each set of exhaust holes 52 contains several exhaust holes 52, which are evenly distributed around the outer circumference of the air blowing pipe 50. Each exhaust hole 52 penetrates the wall of the air blowing pipe 50, and its axis forms an angle with the axis of the air blowing pipe 50. One end of the air blowing pipe 50 is connected to an external air source pipeline, while the other end is closed.

[0055] When the hanger 30 drives the workpiece 20 to rotate so that the mold cavity 21 faces the horizontal direction, the air blowing pipe 50 rotates around the rotation axis to a preset angle. With the help of an external driving force, the air blowing pipe 50 is driven to rotate, so that several exhaust holes 52 of the same group on the air blowing pipe 50 take turns blowing the inside of the mold cavity 21 to form a flow blowing. Each group of exhaust holes 52 is distributed along the axis of the air blowing pipe 50 and acts on different axial areas of the mold cavity 21 respectively.

[0056] The rotating connection between the air blowing pipe 50 and the conveying arm 12 ensures that the mold cavity 21 is constantly purged by airflow delivered from different exhaust holes 52, guaranteeing the continuity of the purging operation. Simultaneously, the multi-angle distribution of the exhaust holes 52 allows the airflow to act on the debris from different directions, enhancing the peeling effect on tightly adhered debris and improving the thoroughness of the cleaning. The synergistic effect of the rotating structure and the multi-hole distribution allows the air blowing pipe 50 to adapt to the purging needs of mold cavities 21 of different sizes. While ensuring the cleaning effect, it avoids excessive airflow concentration that could damage the inner wall of the mold cavity 21, providing a clean environment for subsequent processing and ensuring the processing accuracy of the glass mold.
