Description
Technical Field
[0001] The present invention relates to the field of optical module manufacturing, and in particular to an insulating component pre-pressing molding machine for an optical module wiring seat. Background Art
[0002] Optical transceiver modules, also known as optical modules, are used in switches to convert electrical and optical signals, making them a crucial component in optical communications. These modules feature a terminal block for transmitting electrical signals and conducting electricity. The terminal block consists of end caps, pins, and an insulating glass component. The insulating component is pre-pressed into a semi-finished product and then sintered into a finished product.
[0003] In the existing production process, there are certain flaws in the pre-pressing and forming of insulating parts. The pre-pressing and forming of insulating parts requires the coordinated control of mold opening and closing, uniform material loading, and smooth discharge of the finished product. However, existing forming equipment mostly relies on simple mold stamping or a single drive structure to control mold opening and closing, lacking a systematic linkage design: the finished product discharge process mostly relies on a guide ramp to guide the insulating parts into the collection box. Due to the gap between the end of the guide ramp and the collection box, the insulating parts are prone to bumps and scratches due to impact during the falling process. Therefore, it is necessary to design an insulating part pre-pressing and forming machine for optical module terminal blocks.

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0020] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0021] Reference Figures 1 to 7 As shown, an embodiment of the present invention provides an insulating component pre-pressing molding machine for an optical module terminal block, comprising a processing table 1, a loading assembly 2, a molding assembly 3, a blanking assembly 4, and a stacking assembly 5; The forming assembly 3 includes a chassis 31 fixedly mounted on the processing table 1, and a rotating unit is installed on the chassis 31. The rotating unit includes a central column 301 that passes through the fixed processing table 1 and is located at the center of the chassis 31. The chassis 31 is an annular structure. Three groups of L-shaped fixing parts 33 are evenly distributed on the upper surface of the chassis 31 in the circumferential direction. Each group of fixing parts 33 is connected to the outer edge of the fixing ring 32 by bolts to form a rigid support structure. A through hole (not shown in the figure) larger than the diameter of the central column 301 is opened in the center of the fixing ring 32. The central column 301 coaxially passes through the fixing ring 32. A certain distance is reserved between the inner wall of the through hole and the outer cylindrical surface of the central column 301 to ensure that the central column 301 can rotate freely without getting stuck.
[0022] A central rotating disc 36 is coaxially nested on the outside of the center column 301. The lower surface of the central rotating disc 36 forms a sliding fit with the upper surface of the retaining ring 32, and the contact surface is ground to reduce friction. Multiple groups of mold cavities 361 are evenly distributed along the circumference of the central rotating disc 36. The axis of each group of mold cavities 361 is parallel to the axis of the center column 301, and is used to accommodate the material to be processed and perform the molding operation. At the same time, a lower turntable 34 is fixedly installed on the central column 301 at the lower end of the central turntable 36. The lower turntable 34 has multiple groups of through-type sliding grooves (not marked in the figure) evenly distributed along its circumference. A columnar lower mold base 341 is adapted to be installed in each group of sliding grooves. The central axis of each group of lower mold base 341 is coaxial with the mold cavity 361 at the corresponding position on the central turntable 36. A lower mold body 342 is fixed to the end of the lower mold base 341 facing the mold cavity 361 by bolts. The shape of the lower mold body 342 is adapted to the bottom contour of the mold cavity 361. A lower driving groove 312 is formed on the outer circumference of the central column 301 along its circumference. The lower driving groove 312 is used to drive the lower mold body 342 to move up and down. A lower driving rod 343 is fixedly mounted on the outer end surface of each group of lower mold bodies 342. The outer end of the lower driving rod 343 is designed as a spherical structure. The spherical structure is embedded in the lower driving groove 312 and forms a rolling pair connection therewith. When the lower turntable 34 rotates, it drives the lower die holder 341 in a circular motion around the center column 301. At this point, the spherical end of the lower drive rod 343 slides along the path of the lower drive groove 312, converting the circular motion into linear reciprocating motion within the sliding groove. By designing the lower drive groove 312 as a continuous curve, the lower die body 342 can precisely enter and exit the die cavity 361, completing the pressing of the material.
[0023] To ensure motion accuracy, a clearance fit is adopted between the lower die base 341 and the through-groove, and a self-lubricating, wear-resistant coating is applied to the contact surface. The spherical end of the lower drive rod 343 is inlaid with a bearing steel ball, forming a low-friction pair with the quenched surface of the lower drive groove 312, effectively reducing motion resistance and wear. At the same time, an upper turntable 35 is fixedly mounted on the center column 301 and is located at the upper end of the middle turntable 36. The upper turntable 35 has multiple groups of through-type movable grooves (not marked in the figure) evenly distributed along its circumference. A columnar upper die seat 351 is adapted to be mounted in each group of movable grooves. The central axis of each group of upper die seats 351 is coaxial with the die cavity 361 at the corresponding position on the middle turntable 36. An upper die body 352 is fixed to the end of the upper die seat 351 facing the die cavity 361 by bolts. The shape of the upper die body 352 is adapted to the overall contour of the die cavity 361. An upper driving groove 311 is formed on the outer circumference of the center column 301 along its circumference. The upper driving groove 311 is used to drive the upper mold body 352 to move up and down. An upper driving rod 353 is fixedly mounted on the outer end surface of each set of upper mold bodies 352. The outer end of the upper driving rod 353 is designed as a spherical structure. The spherical structure is embedded in the upper driving groove 311 and forms a rolling pair connection with it. In the technical solution of this application, a drive device is integrated within the processing table 1. This device uses an electric motor as its power source and achieves power transmission and direction conversion by driving a bevel gear set. Specifically, the auxiliary gear is connected to the center column 301 via a bearing sleeve. The auxiliary gear is connected to the bottom surface of the lower turntable 34 using fasteners. The main gear is installed at the output end of the motor. The auxiliary gear meshes with the main gear to ensure that power can be effectively transmitted from the bevel gear set to the lower turntable 34. This design allows the lower turntable 34 to achieve stable rotational motion under the drive device, providing a reliable motion foundation for subsequent processing steps such as glass powder molding. When the drive mechanism rotates the lower turntable 34, the upper turntable 35 rotates synchronously, driving the upper die holder 351 in circular motion around the center post 301. At this point, the spherical end of the upper drive rod 353 slides along the path of the upper drive groove 311, converting the circular motion into linear reciprocating motion within the movable groove. By designing the curve of the upper drive groove 311, the upper die body 352 can enter or exit the die cavity 361 within a specific angular range, effectively collaborating with the lower die holder 341 to compress and release the material.
[0024] A feeding portion is mounted on the fixing ring 32. The feeding portion includes a fan-shaped powder seat 37 fixed to the fixing ring 32 by fasteners. The inner arc surface of the powder seat 37 maintains a uniform gap with the outer circular surface of the center column 301, and the outer arc surface is flush with the outer edge of the fixing ring 32, forming an annular powder cavity 371. The fan-shaped structural design perfectly adapts to the rotation path of the turntable 36, so that the powder seat 37 covers the feeding area of the local mold cavity 361. A scraper 372 is fixedly mounted inside the powder holder 37 and is arranged at an angle. Its lower end is made of an elastic, wear-resistant material and maintains a constant gap with the upper surface of the turntable 36. The scraper 372 is used to scrape off powder. A powder inlet pipe 373 is connected to the powder holder 37 and is adapted to communicate with an external powder feeding device to supply powder into the powder chamber 371. When the powder enters the powder cavity 371 through the powder inlet tube 373 and falls on the upper end surface of the turntable 36, as the turntable 36 rotates, the stationary scraper 372 evenly fills the powder into the mold cavity 361 and scrapes off excess powder to ensure that the powder filling amount in each mold cavity 361 is consistent and the surface is flat.
[0025] The powder inlet pipe 373 is connected to the external powder supply device through a quick-release sealing joint to form a continuous and stable powder supply channel.
[0026] The axial extension length of the upper driving groove 311 is greater than that of the lower driving groove 312. This design enables the upper die base 351 and the lower die base 341 to form a height difference when they move synchronously to the scraping station, thereby achieving smooth demolding and discharge of the material. In order to discharge the pressed material, Figure 2 As shown, the chassis 31 is mounted with an arc-shaped scraper unit. This unit includes an arc-shaped scraper element 310 mounted to the edge of the chassis 31 via fasteners. Its base precisely mates with the upper surface of the turntable 36, forming a smooth scraper interface. A downward-angled guide ramp 39 is fixedly connected to the outer edge of the fixed ring 32. Its inlet end seamlessly connects with the outlet end of the scraper element 310, forming a material conveying channel. When the mold cavity 361 rotates to the discharge station, the upper mold base 351, guided by the upper drive groove 311, drives the upper mold body 352 upward out of the mold cavity 361 and moves it above the scraper 310. Simultaneously, the lower mold base 341, driven by the lower drive groove 312, pushes the pressed and formed insulating member upward, causing its top to protrude above the upper surface of the turntable 36. At this point, the rotating turntable 36 drives the formed insulating member into relative motion with the stationary scraper 310. The curved working surface of the scraper 310 peels the insulating member from the surface of the lower mold body 342 and guides it to slide along the arc of the scraper 310.
[0027] Under the combined effects of centrifugal force and gravity, the scraped insulation enters the material guide ramp 39 and slides naturally along the inclined channel. The inner surface of the scraper 310 is polished to reduce material conveying resistance. The tilt angle of the material guide ramp 39 is optimized based on the physical properties of the insulation, ensuring smooth material flow and preventing accumulation. The entire discharge process, through the precise coordination of the mechanical structure, achieves continuous and automatic unloading of the formed products without manual intervention.
[0028] In order to facilitate the centralized collection of fallen materials, such as Figure 5-Figure 7 As shown, the unloading assembly 4 includes a conveyor 41, on which a collection box 43 is placed for receiving the molding materials sliding down from the material guide inclined plate 39. Limiting plates 42 are fixedly mounted parallel to the two side edges of the conveyor 41. The two sets of limiting plates 42 are parallel to each other and the spacing is adapted to the width of the collection box 43, forming a lateral limit for the collection box 43 to prevent it from deflecting during the conveying process. The upper edge of the limiting plate 42 is provided with an inward folded edge to further enhance the restraining effect on the collection box 43. A material discharge portion is connected and installed between the two groups of limiting plates 42. The material discharge portion includes a support member 44 fixedly installed on the two groups of limiting plates 42. The two groups of support members 44 are rigidly connected by a horizontal connecting rod 45 to form a stable load-bearing frame. A support tray 46 is movably sleeved on the connecting rod 45. The support tray 46 can rotate freely around the axis of the connecting rod 45. Its rotation axis is perpendicular to the conveying direction of the conveyor 41. A pressure sensor (not shown in the figure) is embedded in the support tray 46. The two sides of the support tray 46 are respectively connected to the second cylinder 411 and are movably connected to the piston rod of the second cylinder 411. The other end of the second cylinder 411 is hinged to the outer side of the limiting plate 42 through a fixing rod 49. At the same time, a hopper 47 is placed on the support tray 46. The bottom of the hopper 47 is provided with a vertically arranged long strip discharge trough 471. The width of the discharge trough 471 is greater than the outer diameter of the molded insulating parts, so that they are suitable for being arranged and placed in the discharge trough 471, ensuring that the insulating parts can be neatly arranged in the trough to avoid mutual squeezing or rolling. Limiting sections 48 are also provided at the bottom of support tray 46, near the four corners. These sections utilize a guide post and sleeve structure, with the guide post ends fixedly connected to the bottom of hopper 47, while the guide sleeve ends engage corresponding holes in support tray 46, forming a sliding connection. This design not only limits the horizontal displacement of hopper 47 but also provides free vertical movement, allowing it to maintain close contact with the pressure sensor under the influence of gravity. At the same time, a PLC control system is provided on the processing table 1, and the PLC control system is used to control the operation of the above equipment; The receiving hopper 47 has an outwardly extending expansion portion. When the pressure sensor detects that the receiving hopper 47 has reached a preset weight, the PLC control system triggers the second cylinder 411 to move, pushing the support tray 46 to rotate around the connecting rod 45, so that the collection box 43 is tilted for unloading, so as to facilitate the discharge of the formed insulating parts into the collection box 43. When the support tray 46 is driven by the second cylinder 411 to rotate to the unloading position, the expansion portion end of the receiving hopper 47 is in a close position to the feed port of the collection box 43, and the bottom surface of the expansion portion forms a certain inclination angle with the horizontal plane, ensuring that the insulating parts can slide smoothly along the inner surface of the expansion portion into the collection box 43 under the action of gravity, avoiding material jamming or splashing. A buffer spring is sleeved on the outside of the guide post of the limiting portion 48. One end of the spring abuts the lower surface of the support tray 46, and the other end contacts the bottom of the receiving hopper 47. When the receiving hopper 47 bears the weight of the insulating components, the buffer spring is compressed, providing a certain buffering force, reducing the impact on the receiving hopper 47 and the pressure sensor. At the same time, the preload of the spring ensures that the receiving hopper 47 will not detach from the support tray 46 due to vibration during the unloading process, ensuring the stability and reliability of the structure. The design of the entire receiving hopper 47 enables the orderly collection and directional unloading of insulating components, improving the efficiency and quality of material handling.
[0029] In order to load the powder, the loading assembly 2 includes a mounting frame 21 fixedly mounted on the processing table 1. A vertically arranged support rod 22 is welded to the vertical section of the mounting frame 21. The outer peripheral surface of the support rod 22 is axially spaced and sleeved with two sets of limiting parts. Each set of limiting parts is composed of a connecting frame 23 and a limiting ring 24. The connecting frame 23 is tightly connected to the support rod 22, and the limiting ring 24 is welded to the free end of the connecting frame 23. The two sets of limiting parts are arranged in an upper and lower position. The lower surface of the limiting ring 24 at the lower end is welded with a support ring 25. The outer diameter of the support ring 25 is smaller than that of the limiting ring 24, forming a stepped bearing surface. A powder barrel 26 with a conical structure is sleeved on the limiting part. The powder barrel 26 with a conical structure is sleeved between the two sets of limiting parts. Its large diameter end overlaps the support ring 25, and the small diameter end extends downward as a discharge port. The discharge end of the powder barrel 26 is connected to the powder inlet pipe 373 through a hose 28. The discharge end of powder barrel 26 is connected to one end of hose 28 via a quick-release fitting. The other end of hose 28 is threaded and sealed to powder inlet pipe 373, forming a sealed powder delivery channel. Hose 28 is made of a flexible, wear-resistant material, effectively buffering the impact of powder flow and accommodating minor vibrations during equipment operation. A feed port is located at the top of powder barrel 26, equipped with a sealing cap for easy replenishment and equipment cleaning. A flow regulating valve and a pressure sensor are provided inside the powder inlet pipe 373, which can accurately control the powder supply amount according to production requirements.
[0030] The conical powder barrel 26 is stably supported between the stoppers by a support ring 25. Its larger diameter end faces upward, facilitating the storage of large quantities of powder. The powder naturally falls to the discharge port under the influence of gravity, entering the powder inlet pipe 373 through the hose 28. The flexible design of the hose 28 ensures that the connection between the powder barrel 26 and the stoppers remains sealed despite vibration and thermal expansion and contraction, while also buffering the impact of the powder flow.
[0031] The flow control valve and pressure sensor within powder inlet pipe 373 form a closed-loop control system. The pressure sensor monitors the powder pressure within the pipe in real time and feeds the signal back to the controller. When the pressure falls below a set threshold, the controller opens the control valve wider, increasing the powder supply; otherwise, it closes the valve, achieving dynamic flow balance.
[0032] In order to centrally stack the collection boxes 43 of the stacked insulating parts, as shown in FIG. Figure 5-Figure 7 As shown, the stacking assembly 5 includes a support base 51 fixedly mounted at one end of the conveyor 41. Two sets of concave support side plates 52 are arranged in parallel on the support base 51. The spacing between the two sets of concave support side plates 52 matches the width of the collection box 43, forming a vertical guide channel for the collection box 43 to ensure that the box body is accurately positioned. Inside the two sets of support side plates 52, multiple sets of support parts are symmetrically arranged along the vertical direction to achieve layered support of the collection box 43. The support portion includes a limiting rod 55 fixedly installed in the supporting side plate 52, and a movable rod 56 is installed on a bearing at a side position of the limiting rod 55 in the supporting side plate 52. Two groups of supporting parts 57 are fixedly installed on the movable rod 56. The two groups of supporting parts 57 have a spacing to match the side support requirements of the collection box 43, and a first notch part 58 is provided at the end thereof. The supporting part 57 is installed on the movable rod 56 in an eccentric sleeve manner, and its unique eccentric structure realizes functional zoning design. The larger eccentric area precisely adapts to the size and weight of the collection box 43, providing a stable support for the collection box 43 and ensuring a smooth and reliable material receiving process; the smaller eccentric area is used to contact and cooperate with the limit rod 55. By precisely controlling the eccentricity, the supporting portion 57 can be accurately engaged or separated from the limit rod 55 when moving under the drive of the movable rod 56, thereby achieving precise position limitation and flexible switching. In the initial state, the notch is in contact with the bottom surface of the limit rod 55, and the supporting force of the limit rod 55 is used to keep the supporting portion 57 in a horizontal position, forming a temporary bearing surface for the collection box 43. At the same time, a pushing part is installed on the support base 51 to drive the collection box 43 to complete the vertical lifting. The pushing part includes a first cylinder 53 fixedly installed on the support base 51 and located below the support part. A support plate 54 is fixedly installed at the telescopic end of the first cylinder 53. In the initial state, the support plate 54 is flush with the surface of the conveyor 41, eliminating the material drop and ensuring a smooth transition of the collection box 43. The fully loaded collection box 43 is transported to the stacking station by the conveyor 41 and naturally falls onto the support plate 54. The first cylinder 53 extends, pushing the support plate 54 to vertically rise with the collection box 43 until it reaches the critical position below the uppermost supporting portion 57. The collection box 43 is pushed by the first cylinder 53 and the lower edge of the support portion 57 contacts the supporting portion 57, and pushes the supporting portion 57 to rotate axially around the movable rod 56. The supporting portion 57 deflects synchronously. During the collection box's ascent, the supporting portion 57 in contact with it drives the movable rod 56 to rotate. At this time, the first notch portion 58 swings downward and separates from the limit rod 55, and the supporting portion 57 is lifted. 7 swings upward away from the first notch portion 58 to avoid the collection box, and then the collection box continues to rise and passes over the supporting portion 57 at the corresponding position. At this time, the movable rod 56 is reset, and the first notch portion 58 swings upward until it abuts against the limit rod 55. Then the collection box descends and is supported by the end of the supporting portion 57 at the corresponding position away from the first notch portion 58, releasing the carrying space. The collection box 43 continues to rise with the support plate 54, and after passing the inclined supporting portion 57, the first cylinder 53 pauses briefly; the supporting portion 57 is flattened due to the eccentric installation, and the collection box 43 falls and rests on the upper surface of the supporting portion 57, completing one layer of stacking.
[0033] In this application, an arc-shaped shielding member is positioned near the outlet section of the guide ramp 39. Its shape matches the inner arc of the guide ramp 39 and is hinged to the side wall of the guide ramp 39 via a pivot. The shielding member's pivot extends outside the guide ramp 39 and is rigidly connected to the output shaft of a power driver (such as a rotary cylinder or servo motor), forming a controllable, rotatable blocking mechanism. When the molded insulating members within the receiving hopper 47 reach a specified weight, the shielding member blocks the temporarily collected molded insulating members within the guide ramp 39 until the receiving hopper 47 is reset. Working principle: When the insulating component pre-pressing molding machine is in use, the conical powder barrel 26 of the feeding component 2 stores powder, which is transported to the powder holder 37 by gravity through the hose 28 and the powder inlet pipe 373. The flow regulating valve and the pressure sensor of the powder inlet pipe 373 are closed-loop controlled to ensure a stable supply of powder. When the turntable 36 rotates, the scraper 372 in the powder holder 37 evenly fills the powder into the mold cavity 361 and scrapes off the excess material to ensure filling accuracy.
[0034] When the drive mechanism rotates lower turntable 34, it also drives upper turntable 35 to rotate synchronously. Driven by the drive groove, upper and lower mold bases 351 and 341 perform linear reciprocating motion along the movable / sliding grooves. The upper and lower mold bodies 342 precisely mate with each other, compacting the powder in mold cavity 361 and completing the insulation molding process.
[0035] The upper drive groove 311 is axially longer, creating a height difference between the upper and lower mold bases 341 at the scraping station. When the mold cavity 361 rotates to the discharge position, the upper mold body 352 is ejected, and the lower mold body 342 ejects the molded insulating component. The rotating center turntable 36 drives the insulating component and the stationary scraping element 310 into relative motion. After being stripped, the insulating component slides along the scraping element 310 into the guide ramp 39, where it falls to the discharge assembly 4 under the action of gravity and centrifugal force.
[0036] In the unloading assembly 4, a hopper 47 temporarily stores insulating components. A pressure sensor monitors the weight. When the weight reaches a preset value, a second cylinder 411 drives the support tray 46 to flip, allowing the insulating components to slide along the unfolded portion into the collection box 43. The conveyor 41 delivers the fully loaded collection box 43 to the stacking station. The first cylinder 53 of the stacking assembly 5 pushes the support plate 54 to lift the collection box 43, which then cooperates with the support portion 57 to receive the components in layers, achieving automatic stacking. Each process is coordinated by a PLC control system, achieving continuous and automated production.
