Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical module manufacturing, in particular to a manufacturing device of an optical module terminal seat and a production process thereof. BACKGROUND

[0002] An optical transceiver module, referred to as an optical module, can be used in a switch to complete the conversion between an electrical signal and an optical signal, and is an important component in optical communication. The optical module has a terminal seat for transmitting an electrical signal and conducting electricity, which is composed of an end cap, a pin and an insulating part. The insulating part is insulating glass, and the end cap is usually made of steel plate and is formed by a stretching stamping process. Its role is to provide physical protection for the internal structure and participate in the construction of electrical connection. The pin is usually made of a special wire material and is processed by a plate mold, which bears the key responsibility of current conduction and requires good electrical conductivity and mechanical strength. The glass bead is prepared by pre-pressing and pre-sintering of glass powder, which plays a dual role of electrical insulation and sealing in the terminal seat, and its quality directly affects the running stability of the terminal seat in complex environments such as high pressure and humidity.

[0003] In the current production of end caps, stamping equipment usually uses mechanical presses or hydraulic presses. Mechanical presses can provide stable and large stamping force due to their high rigidity body structure. Common open or closed mechanical presses have stamping forces ranging from tens of tons to hundreds of tons, which can meet the stamping needs of end caps of different specifications.

[0004] The end cap stamping die is a core element that determines the quality of the product. The die is usually composed of an upper die seat, a lower die seat, a male die, a female die, and a guide device. The design of the male die and the female die is based on the specific shape and size of the end cap, and precise numerical control processing equipment is used for manufacturing to ensure the accuracy of the die surface.

[0005] However, in the end cap stamping process, the traditional equipment is limited by the design defects of automation. After the upper die completes the stamping and the slider moves up, the lower die fixed on the workbench relies heavily on manual operation during the unloading process. Workers need to use tools to take out the end caps from the female die cavity one by one. This manual unloading method not only consumes time and effort, but also is affected by the operation proficiency and fatigue, and is prone to unloading delays or improper placement of end caps, which may cause end caps to be left in the die and cause subsequent stacking stamping, or cause end cap deformation and surface damage during the unloading process due to uneven force. Therefore, it is necessary to design a manufacturing device of an optical module terminal seat and a production process thereof.

[0006] It should be noted that the above information disclosed in the background section of the present application is only used to understand the background of the present application, and therefore, it can contain information that does not constitute prior art. SUMMARY

[0041] The punch assembly 1 comprises a workbench one 11, and a unwinding unit is installed on the workbench one 11, the unwinding unit comprises a support frame 12 fixedly installed on the workbench one 11, and a horizontal unwinding roller 13 is bearingly installed on the support frame 12, and a steel plate roll is wound on the unwinding roller 13;

[0042] Meanwhile, the straightening unit is arranged on one side of the unwinding unit on the workbench 11, the straightening unit comprises two groups of side frames 14 fixedly installed on the workbench 11, a supporting roller 15 is bearing installed between the two groups of side frames 14, the supporting roller 15 is used for supporting the steel plate, a cylinder 17 is fixedly installed at the top end of the side frame 14, the lower end of the telescopic rod of the cylinder 17 is connected with a bearing sleeve 18 through a flange, a compression roller 16 is bearing connected between the two bearing sleeves 18, the surface of the compression roller 16 is polished to reduce the frictional resistance with the steel plate, the axis of the compression roller 16 is parallel to the supporting roller 15 and perpendicular to the conveying direction of the steel plate, the compression roller 16 is driven to move close to or away from the supporting roller 15 through the telescopic action of the cylinder 17, the elastic compression and dynamic straightening adjustment of the steel plate with different thicknesses are realized, and it is ensured that the steel plate enters the subsequent processing station in a flat state.

[0043] And a stamping unit is installed on the workbench 11, the stamping unit comprises a support 19 fixedly installed on the workbench 11, a supporting seat 110 is fixedly installed below the support 19 on the workbench 11, a fixed part 111 is fixedly installed on the supporting seat 110, the fixed part 111 is composed of two groups of side plates and a fixed rod, the fixed rod is bearing installed between the two groups of side plates, a lower die 112 is fixedly connected with the fixed rod through two groups of sleeve connecting parts 113, the lower die 112 is provided with a mold cavity 114.

[0044] And a hydraulic cylinder 115 is fixedly installed at the top end of the support 19, an upper die 116 is fixedly installed at the telescopic end of the hydraulic cylinder 115, the upper die 116 is driven to close or separate from the lower die 112 through the linear reciprocating motion of the hydraulic cylinder 115, the continuous stamping forming of the steel plate is realized, and two groups of guide rods 117 are fixedly installed on the upper die 116, the guide rods 117 are arranged through the support 19, and the guide rods 117 are used for guiding the moving direction of the lower die 112.

[0045] The two ends of the fixed rod respectively pass through the side plates at the two ends, a gear 118 is key connected and installed at one end of the fixed rod, a rack 119 suitable for engaging with the gear 118 is fixedly installed at the bottom of the upper die 116, the rack 119 is composed of a smooth section and a tooth block section, in the initial state, the smooth section of the rack 119 keeps in contact with the gear 118, at this time, the lower die 112 is rigidly connected with the fixed rod through the sleeve connecting part 113, and is turned outwards to the limit position (turned outwards by 130 degrees) around the axis of the fixed rod.

[0046] When the hydraulic cylinder 115 drives the upper mold 116 to move downward, the toothed segment of the rack 119 meshes with the gear 118, driving the fixed rod to rotate counterclockwise, thereby causing the lower mold 112 to flip inward and reset to the vertical stamping position. When the toothed segment on the rack 119 passes the gear 118, the lower mold 112 is in a horizontal state. As the upper mold 116 continues to move downward, the upper mold 116 gradually approaches the lower mold 112 and completes the stamping action.

[0047] After stamping is completed, when the upper die 116 returns, the smooth section of the rack 119 first contacts the gear 118. At this time, the upper die 116 first moves away from the lower die 112, and as the upper die 116 continues to drive the rack 119 to move upward, the tooth block section of the rack 119 contacts the gear 118, and then drives the gear 118 in the opposite direction, so that the lower die 112 flips outward again to the initial position, so as to facilitate the gravity unloading of the workpiece.

[0048] To facilitate the receiving / unloading of the end caps stamped in the lower die 112, such as Figures 4-5 As shown, a rectangular fixing frame 126 is embedded at one end of the workbench 11. A collection box 127 is slidably inserted into the side of the fixing frame 126. A buffer pad is provided in the inner cavity of the collection box 127 to reduce the impact damage of the end cap. A striking unit is symmetrically installed on the left and right sides of the bracket 19. The two sets of striking units are located on both sides of the lower mold 112. The striking unit includes a motor 120 fixedly installed on the bracket 19. The output end of the motor 120 is keyed to a disc cam 121. The cam 121 is adapted to rotate with the output end of the motor 120.

[0049] A support rod 122 is fixedly installed on the fixed frame 126. A movable rod 123 passes through the support rod 122, and a spring 124 is sleeved on the movable rod 123. An anti-detachment part is fixedly installed at one end of the support rod 122. The two ends of the spring 124 abut against the stepped surface of the anti-detachment part and the end face of the support rod 122, respectively. The anti-detachment part is adapted to maintain contact with the contour of the cam 121 under the action of the spring 124. The left end of the movable rod 123 is threadedly connected to a striking part 1. 25. The striking part 125 is made of polyurethane elastomer material. When the lower mold 112 is flipped outward, the arc groove of the striking part 125 is precisely fitted with the outer side wall of the lower mold 112. When the motor 120 drives the cam 121 to rotate, the preload of the spring 124 causes the movable rod 123 to produce reciprocating linear motion, thereby driving the striking part 125 to periodically strike the lower mold 112. The auxiliary end cap falls out of the mold cavity 114 and falls into the collection box 127.

[0050] The release roller 13 rotates to release the steel plate roll, and the steel plate then enters the straightening unit, is supported by the support roller 15 supported by the side frame 14, and the air cylinder 1 17 drives the bearing sleeve 18 connected to the pressure roller 16 to move up and down, and the dynamic straightening of the steel plate is achieved through elastic pressure adjustment;

[0051] The straightened steel plate enters the stamping station, the hydraulic cylinder 115 at the top end of the support 19 drives the upper die 116 to move up and down along the guide rod 117, and the lower die 112 connected to the fixed part 111 on the support seat 110 is closed for stamping. The gear 1 18 at both ends of the fixed rod is engaged with the rack 119 at the bottom of the upper die 116 to form a linkage: when the upper die 116 descends, the rack 119 tooth block segment is engaged with the gear 1 18 to drive the fixed rod to rotate counterclockwise, and the lower die 112 is flipped from the initial position of 130 degrees outward to the inside to the vertical stamping station; when the rack 119 tooth block segment passes the gear 1 18, the lower die 112 is in a horizontal state, and the upper die 116 continues to descend to complete the stamping. After stamping, the upper die 116 returns, the smooth segment of the rack 119 first contacts the gear 1 18 to move away from the upper die 116, and then the tooth block segment drives the gear 1 18 in the opposite direction, and the lower die 112 is flipped outward again, facilitating the gravity of the end cap to unload;

[0052] In the end cap loading / unloading link, the collection box 127 is slidably inserted into the fixed frame 126 embedded in one end of the workbench 1 1, and the inner cavity cushion pad reduces the impact of the end cap. The motor 1 20 on both sides of the support 19 drives the cam 121 to rotate, and the profile of the cam 121 pushes the movable rod 123 through the pre-tightening force of the spring 124, so that the knocking part 125 periodically knocks the outer side wall of the flipped lower die 112. When the lower die 112 is flipped outward to the horizontal unloading position, the knocking part 125 is attached to the lower die 112, which helps the end cap to fall off from the mold cavity 114 and fall into the collection box 127 through gravity, realizing automatic loading / unloading.

[0056] When the motor 26 is started, the output shaft drives the belt pulley 27 to rotate, and the power is transmitted to the belt pulley 210 on the roller shaft through the belt body, so as to drive the roller shaft to rotate. The gear 29 fixedly arranged on the roller shaft rotates, and is engaged with the gear 211, so as to convert the rotating motion and transmit the torque.

[0057] When the gear 211 rotates, the connecting arm 212 hingedly arranged on the eccentric position of the gear 211 rotates along the circumference. One end of the connecting arm 212 is movably connected with the lower plate 214, and the lower plate 214 is driven by the gear 211 to move along the guide rail on the limiting plate 213 in a straight line. In this process, the lower plate 214 and the upper plate 23 arranged in an inclined manner form a periodic relative motion, and the small gap between the two can rub and extrude the wire processed by the wire leading part 24 and the straightening part 25. When the wire passes through the gap between the upper plate 23 and the lower plate 214, the wire is gradually processed into the pin shape according to the specification under the action of the tooth structure, and finally is discharged from the discharging port 215 of the processing box 22, so as to realize the automatic wire rubbing processing.

The bottom rack 119 is engaged with the gear one 118 at both ends of the fixed rod, which drives the lower die 112 to flip inward from the initial position of 130 degrees outward to the vertical station. When the rack 119 tooth block segment passes through the gear one 118, the lower die 112 is in a horizontal state, and the upper die 116 continues to descend to complete the stamping. During the return stroke, the smooth section of the rack 119 first contacts the gear one 118 to move the upper die 116 away, and then the tooth block segment drives the gear one 118 in the reverse direction, and the lower die 112 flips outward to the unloading position. The knocking unit on both sides of the support 19 drives the cam 121 through the motor one 120, and the spring 124 linkage knocking part 125 periodically knocks the lower die 112, which helps the end cap to fall off from the mold cavity 114 and fall into the collection box 127, realizing the integration of stamping and unloading.

[0068] The pretreated wire is introduced into the wire drawing assembly 2 through the lead-in part 24. The two groups of extrusion wheels of the front end straightening part 25 rotate synchronously and reversely to eliminate the bending deformation of the wire and send it into the processing box 22. The motor two 26 drives the roller shaft to rotate through the belt pulley one 27, the belt pulley two 210, the gear two 29, and the gear three 211. The gear two 29 is engaged with the gear three 211 to drive the eccentrically connected connecting arm 212 to swing, so that the lower rubbing plate 214 moves linearly along the guide rail of the limiting plate 213. The fixed inclined upper rubbing plate 23 and the reciprocating lower rubbing plate 214 form a small gap, which is processed into the required pin shape by relative rubbing and extrusion of the tooth surface, and finally discharged from the discharge port 215, realizing high-precision wire drawing forming.

[0069] The lower die seat 36 of the forming assembly 3 is intermittently rotated under the drive of a driving member such as a stepping motor, and the annular protruding portion at the circumferential edge thereof prevents overflow of the powder. In the feeding unit, the cylinder 311 drives the slide table 310 to align the discharge pipe 316 of the powder cylinder 314 with the die hole, the PLC controls the opening of the pneumatic butterfly valve, and the glass powder stirred by the stirring unit 315 falls into the die hole; when the lower die seat 36 rotates, the scraper outside the discharge pipe 316 scrapes the overflowed powder flat to ensure uniform filling. When the die hole rotates to the pressing station, the lifting rod 33 drives the upper die seat 34 to descend along the guide 37, and the die hole of the lower die seat 36 is closed to complete the pre-pressing; after continuing to rotate to the demolding station, the semi-finished glass ball is demolded by the ejection mechanism. The whole process realizes the full-automatic circulation from powder filling to forming and demolding by coordinating the action timing of the driving member, the cylinder, the lifting rod 33 and the stirring unit 315 through the PLC system.

[0070] Embodiment two: the production process of the above optical module terminal is as follows:

[0071] Step one: after the steel plate is unwound and straightened, the end cap is punched at the punching station, and is collected with the aid of the knocking unit;

[0072] Step two: after the wire is straightened, the pin is formed by rubbing and is led out;

[0073] Step three: after the glass powder is blanked and scraped flat, the semi-finished glass ball is pre-pressed and demolded;

[0074] Step four: the punched end cap, the rubbed pin and the pre-pressed glass ball are assembled, and are sintered in a sintering furnace;

[0075] Step five: the sintered assembly is subjected to chemical plating, silicon oil treatment, and finally completes the sealing test.

[0076] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above disclosed technical content to obtain equivalent embodiments with equivalent changes, without departing from the technical solution of the present application.
