Description

Technical Field

[0001] This utility model relates to the field of glass microsphere technology, and in particular to a polishing machine for prefabricated infrared chalcogenide glass microspheres. Background Technology

[0002] Infrared chalcogenide glass lenses are mainly used in automotive and surveillance products. These lenses are primarily produced using two methods: precision molding or single-point diamond turning of infrared chalcogenide glass raw materials. Precision molding involves processing the raw material into pre-formed small spheres before molding.

[0003] The production process of infrared chalcogenide glass preforms is as follows: the outer circle cutting machine cuts the long strip of optical glass into short strips, the inner circle cutting machine cuts the short strips into square particles, and the square particles are then processed by a series of processes such as chamfering, rounding, fine grinding, polishing and cleaning to obtain infrared chalcogenide glass preforms.

[0004] Existing polishing machines (such as the polishing device for processing optical glass spheres disclosed in application number 202120096743.9) can only polish a single pre-made sphere at a time, resulting in low efficiency when polishing pre-made spheres in batches. Utility Model Content

[0005] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an infrared chalcogenide glass pre-made small ball polishing machine to solve the technical problem of low efficiency of existing polishing machines when performing batch polishing of pre-made small balls.

[0009] Multiple positioning mechanisms are connected one-to-one with each of the collars to position each of the collars;

[0010] A drive mechanism, which is connected to the polishing disk, is used to drive the polishing disk to rotate about its axis.

[0011] Furthermore, each of the loading mechanisms also includes multiple carrier trays, each carrier tray is laid flat in the loading area and abuts against the collar, and multiple placement slots are provided on the carrier trays, each placement slot being used to place a pre-made small ball.

The rotating shaft is vertically disposed above the spline shaft and coaxially and fixedly connected to the spline shaft. The output end of the rotation driving component is coaxially and fixedly connected to the rotating shaft, and is used to drive the rotating shaft to rotate around its axis.

[0015] Furthermore, the infrared chalcogenide glass pre-formed microsphere polishing machine also includes a lifting mechanism. The lifting mechanism is connected to each of the positioning elements in each of the positioning mechanisms and is used to drive each of the positioning elements in each of the positioning mechanisms to move up and down synchronously, so that each of the positioning elements in each of the positioning mechanisms abuts or separates from the corresponding collar. The lifting mechanism is also connected to the driving mechanism and is used to drive the driving mechanism to move up and down, so that the driving mechanism docks or separates from the polishing disc. When the driving mechanism docks with the polishing disc, each of the positioning elements in each of the positioning mechanisms abuts against the corresponding collar.

[0016] Furthermore, the lifting mechanism includes a guide rod, a lead screw, a guide seat, and a mounting bracket. The guide rod and the lead screw are both vertically arranged. The guide seat has a through hole and a screw hole, and is slidably sleeved on the guide rod through the through hole and threadedly sleeved on the lead screw through the screw hole. One end of the mounting bracket is fixedly connected to the guide seat, and the other end of the mounting bracket is rotatably connected to the upper end of each positioning component in each positioning mechanism. The other end of the mounting bracket is also fixedly connected to the fixed end of the rotation drive component.

[0017] Furthermore, the other end of the mounting bracket is rotatably connected to the upper end of each of the positioning shafts in each of the positioning mechanisms, so that the positioning shaft can rotate about its axis.

[0018] Furthermore, the infrared chalcogenide glass pre-formed microsphere polishing machine also includes a transmission mechanism, which is connected to the upper end of the rotating shaft and any one of the positioning shafts in each positioning mechanism, for converting the rotation of the rotating shaft into the synchronous rotation of any one of the positioning shafts in each positioning mechanism, so that each of the collars rotates synchronously.

[0019] The transmission mechanism includes a driving gear and multiple driven gears. The driving gear is coaxially fixedly sleeved on the rotating shaft, and each driven gear is coaxially fixedly sleeved on each positioning shaft. Each driven gear meshes with the driving gear.

Then, each pre-made ball is laid flat in each loading zone, and each pressure plate is set in each loading zone to press the pre-made balls in each loading zone. Each collar is positioned by a positioning mechanism, and the driving mechanism drives the polishing disc to rotate around its axis to polish the pre-made balls in each loading zone. This polishing machine can polish multiple pre-made balls at a time, and has high efficiency when polishing pre-made balls in batches. Attached Figure Description

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0027] This utility model provides an infrared chalcogenide glass pre-formed microsphere polishing machine, the structure of which is as follows: Figure 1 - Figure 4 As shown, the device includes a polishing mechanism 100, multiple loading mechanisms 200, multiple positioning mechanisms 300, and a driving mechanism 400. The polishing mechanism 100 includes a polishing disc 110, which is horizontally arranged. Each loading mechanism 200 includes a collar 210 and a pressure plate. The collar 210 is placed on the polishing disc 110 to enclose a loading area on the polishing disc 110. The loading area is used to lay multiple pre-made small balls flat. The pressure plate is set in the loading area and is used to press the pre-made small balls. Each positioning mechanism 300 is connected to each collar 210 in a one-to-one correspondence to position each collar 210. The driving mechanism 400 is connected to the polishing disc 110 and is used to drive the polishing disc 110 to rotate around its axis.

[0028] In use, each of the collars 210 is placed sequentially on the polishing disc 110, thereby forming multiple loading zones on the polishing disc 110. Then, each pre-made ball is laid flat within each loading zone, and each pressure plate is sequentially placed within each loading zone to press the pre-made balls within each loading zone. Each of the positioning mechanisms 300 positions the collars 210. By manipulating the drive mechanism 400, the polishing disc 110 can rotate around its axis, thus polishing the pre-made balls within each loading zone. This polishing machine can polish multiple pre-made balls at a time, making it highly efficient for batch polishing of pre-made balls.

[0029] As a preferred embodiment, please refer to Figure 4 The collar 210 has multiple grooves 211 circumferentially opened on the end wall that abuts against the polishing disc 110. During the polishing process of the pre-made small ball, polishing powder needs to be sprayed onto the polishing disc 110 and a small amount of water needs to be sprayed onto the polishing disc 110 to improve the polishing effect of the polishing disc 110 on the pre-made small ball. The mixture of polishing powder and water can be discharged along each of the grooves 211.

[0030] As a preferred embodiment, please refer to Figure 1 The polishing mechanism 100 also includes a water tank 120, and the polishing disc 110 is disposed in the water tank 120 and rotatably connected to the water tank 120 via a bearing, so as to collect water.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 4 Each loading mechanism 200 also includes multiple carrier trays 220, each carrier tray 220 is laid flat in the loading area and abuts against the collar 210. Multiple placement slots 221 are provided on the carrier tray 220, and each placement slot 221 is used to place a pre-made ball. The placement slots 221 on the carrier tray 220 can separate the pre-made balls in the loading area, avoid the pre-made balls from rubbing against each other due to contact, and improve the polishing effect of multiple pre-made balls.

[0032] As a preferred embodiment, please refer to Figure 4 The thickness of the carrier plate 220 is less than the diameter of the pre-made small balls, so that the pressure plate can press the pre-made small balls located in each of the placement slots 221.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 3 Each positioning mechanism 300 includes at least three positioning elements 310. Each positioning element 310 is distributed circumferentially above the polishing disk 110 to enclose a positioning area on the polishing disk 110. The positioning area is used to place the collar 210. Each positioning element 310 abuts against the collar 210. The positioning area enclosed by the positioning elements 310 can limit the collar 210, so that the collar 210 will not rotate with the polishing disk 110 during rotation. This allows the polishing disk 110 to move relative to each pre-made ball in the loading area, thereby polishing the pre-made balls.

[0034] As a preferred embodiment, please refer to Figure 2 and Figure 3 The positioning component 310 includes a positioning shaft 311 and a bushing 312. The positioning shaft 311 is vertically arranged, and the bushing 312 is fixedly sleeved on the positioning shaft 311. The bushing 312 abuts against the collar 210. The bushing 312 can abut against the collar 210 to limit the position of the collar 210. The positioning shaft 311 plays a supporting role.

[0035] In a preferred embodiment, the bushing 312 is made of a material with a high coefficient of friction, which can improve the friction between the bushing 312 and the collar 210.

[0036] As a preferred embodiment, please refer to Figure 2 and Figure 3 The drive mechanism 400 is disposed above the polishing disk 110 and includes a spline sleeve 410, a spline shaft 420, a rotating shaft 430, and a rotation drive component 440. The spline sleeve 410 is coaxially and fixedly connected to the polishing disk 110. The spline shaft 420 is disposed above the spline sleeve 410 and engages with it. The rotating shaft 430 is vertically disposed above the spline shaft 420 and coaxially and fixedly connected to it. The output end of the rotation drive component 440 is coaxially and fixedly connected to the rotating shaft 430, and is used to drive the rotating shaft 430 around its axis. The polishing disc 110 and the rotating shaft 430 are detachably connected via the spline sleeve 410 and the spline shaft 420. When the spline shaft 420 is engaged with the spline sleeve 410, the output end of the rotation drive 440 is rotated by operating the rotation drive 440, which drives the rotating shaft 430 to rotate, and in turn drives the spline shaft 420 to rotate. Since the spline shaft 420 is engaged with the spline sleeve 410, the spline sleeve 410 is coaxially and fixedly connected to the polishing disc 110. When the spline shaft 420 rotates, the polishing disc 110 can rotate.

[0037] As a preferred embodiment, please refer to Figure 1 and Figure 2The infrared chalcogenide glass pre-formed microsphere polishing machine further includes a lifting mechanism 500. The lifting mechanism 500 is connected to each of the positioning elements 310 in each of the positioning mechanisms 300, and is used to drive each of the positioning elements 310 in each of the positioning mechanisms 300 to move synchronously up and down, so that each of the positioning elements 310 in each of the positioning mechanisms 300 abuts against or separates from the corresponding collar 210. The lifting mechanism 500 is also connected to the driving mechanism 400, and is used to drive the driving mechanism 400 to move up and down, so that the driving mechanism 400 abuts against or separates from the corresponding collar 210. The polishing disc 110 can be docked or separated. When the driving mechanism 400 is separated from the polishing disc 110, each positioning element 310 in each positioning mechanism 300 is separated from the corresponding collar 210, thereby facilitating the sequential loading and unloading of each collar 210, each carrier plate 220, and each pre-made ball onto the polishing disc 110. When the driving mechanism 400 is docked with the polishing disc 110, each positioning element 310 in each positioning mechanism 300 abuts against the corresponding collar 210, thereby facilitating the polishing of the pre-made ball.

[0038] As a preferred embodiment, please refer to Figure 2 and Figure 3The lifting mechanism 500 includes a guide rod 510, a lead screw 520, a guide seat 530, and a mounting bracket 540. The guide rod 510 and the lead screw 520 are both vertically arranged. The guide seat 530 has a through hole and a threaded hole, and is slidably fitted onto the guide rod 510 through the through hole and threadedly fitted onto the lead screw 520 through the threaded hole. One end of the mounting bracket 540 is fixedly connected to the guide seat 530, and the other end of the mounting bracket 540 is rotatably connected to the upper end of each positioning member 310 in each positioning mechanism 300. The other end of the mounting bracket 540 is also fixedly connected to the fixed end of the rotation drive member 440. When the lead screw 520 is manually rotated forward, the guide seat 530 and the guide rod 520... The lead screw 520 is threaded, and the guide seat 530 is restricted by the guide rod 510. When the lead screw 520 rotates in the forward direction, the guide seat 530 moves upward, driving the mounting bracket 540 to move upward, which in turn drives each of the positioning members 310 and the rotation drive member 440 to move upward until each of the positioning members 310 rises to a preset height. At this time, there is a sufficient gap between the lower end of each of the positioning members 310 and the polishing disk 110. The spline shaft 420 is separated from the spline sleeve 410, and each of the collars 210 is placed on the polishing disk 110 in sequence, with each of the collars 210 located directly below each of the positioning intervals. The positioning intervals can be accessed via each of the collars 210. Multiple loading zones are enclosed on the polishing disc 110. Each of the carrier discs 220 is then laid flat within its respective loading zone, and each pre-made ball is placed sequentially into its corresponding placement groove 221. Each of the pressure plates is then sequentially positioned within its respective loading zone, pressing the pre-made balls within each loading zone. When the lead screw 520 is manually rotated in the reverse direction, the guide seat 530, being threadedly connected to the lead screw 520 and constrained by the guide rod 510, moves downwards. This movement causes the mounting bracket 540 to move downwards, thereby driving the positioning components 310 and the rotation drive... The component 440 moves downward until each of the positioning components 310 descends to a preset height. At this time, the lower end of each positioning component 310 in each positioning mechanism 300 abuts against the corresponding collar 210, and the spline shaft 420 is engaged with the spline sleeve 410. Then, by controlling the rotation drive component 440, the output end of the rotation drive component 440 rotates, driving the rotating shaft 430 to rotate, which in turn drives the spline shaft 420 to rotate. Since the spline shaft 420 is engaged with the spline sleeve 410, and the spline sleeve 410 is coaxially and fixedly connected to the polishing disk 110, when the spline shaft 420 rotates, the polishing disk 110 can rotate, thereby polishing the pre-made small balls in each loading interval.

[0039] As a preferred embodiment, please refer to Figure 2 and Figure 3 The other end of the mounting bracket 540 is rotatably connected to the upper end of each of the positioning shafts 311 in each of the positioning mechanisms 300, so that the positioning shafts 311 can rotate about their axes, thereby allowing the bushings 312 to rotate.

[0040] As a preferred embodiment, please refer to Figure 1 and Figure 2 The infrared chalcogenide glass pre-formed microsphere polishing machine further includes a transmission mechanism 600. The transmission mechanism 600 is connected to the upper end of the rotating shaft 430 and any one of the positioning shafts 311 in each of the positioning mechanisms 300. It is used to convert the rotation of the rotating shaft 430 into the synchronous rotation of any one of the positioning shafts 311 in each of the positioning mechanisms 300, so that each of the collars 210 rotates synchronously. Since the collars 210 abut against each of the carrier disks 220, there is friction between the collars 210 and each of the carrier disks 220. When the collars 210 rotate, they will drive each of the carrier disks 220 to rotate, thereby driving each pre-formed microsphere to rotate, which can further improve the polishing efficiency and polishing effect of the polishing disk 110 on the pre-formed microsphere.

[0041] As a preferred embodiment, please refer to Figure 1 and Figure 2 The transmission mechanism 600 includes a drive gear 610 and multiple driven gears 620. The drive gear 610 is coaxially fixedly sleeved on the rotating shaft 430, and each driven gear 620 is coaxially fixedly sleeved on each positioning shaft 311. Each driven gear 620 meshes with the drive gear 610. When the rotating shaft 430 rotates, it drives the drive gear 610 to rotate. According to the gear meshing transmission principle, each driven gear 620 will rotate synchronously in opposite directions, thereby driving the corresponding positioning shaft 311 to rotate. Since there is friction between the bushing 312 and the corresponding collar 210, when the bushing 312 rotates, it drives the collar 210 to rotate. Since there is friction between the collar 210 and each of the carrier disks 220 inside it, it drives each carrier disk 220 to rotate within the loading area, thereby driving each pre-made ball to rotate, which can further improve the polishing efficiency and polishing effect of the polishing disc 110 on the pre-made balls.

[0042] As a preferred embodiment, the infrared chalcogenide glass pre-formed ball polishing machine further includes a water spraying mechanism, which is used to spray clean water onto the polishing disc 110.

[0043] In a preferred embodiment, the water spraying mechanism may be composed of a water pipe, with one end of the water pipe connected to a water source and the other end of the water pipe used to spray water onto the polishing disc 110.

[0044] As a preferred embodiment, please refer to Figure 1 The infrared chalcogenide glass pre-made small ball polishing machine further includes a housing 700, the water tank 120 is fixedly connected to the housing 700, the lower end of the guide rod 510 is fixedly connected to the housing 700, and the lower end of the lead screw 520 is rotatably connected to the housing 700.

[0045] To better understand this utility model, the following is combined with... Figure 1 - Figure 4 The working principle of the technical solution of this utility model will be described in detail below:

[0046] In use, the lead screw 520 is manually rotated forward. Since the guide seat 530 is threadedly connected to the lead screw 520 and is constrained by the guide rod 510, when the lead screw 520 rotates forward, the guide seat 530 moves upward, causing the mounting bracket 540 to move upward, which in turn causes each positioning member 310 and the rotation drive member 440 to move upward until each positioning member 310 rises to a preset height. At this point, there is sufficient distance between the lower end of each positioning member 310 and the polishing disc 110. The spline shaft 420 separates from the spline sleeve 410, and each collar 210 is placed sequentially on the polishing disc 110, with each collar 210 positioned at its respective position. Directly below the positioning area, multiple loading areas can be formed on the polishing disc 110 via the collars 210. The carrier discs 220 are then laid flat within each loading area, and the pre-made balls are placed sequentially into their corresponding placement slots 221. The pressure plates are then sequentially positioned within each loading area, pressing down on the pre-made balls within each loading area. Manually rotating the lead screw 520 in the reverse direction causes the guide seat 530 to move downwards, driven by the guide rod 510, as the lead screw 520 is threadedly connected to the lead screw 520. This causes each of the positioning elements 310 and the rotation drive element 440 to move downwards until each of the positioning elements 310 descends to a preset height. At this point, the lower end of each positioning element 310 in each positioning mechanism 300 abuts against the corresponding collar 210, and the spline shaft 420 engages with the spline sleeve 410. Then, by manipulating the rotation drive element 440, the output end of the rotation drive element 440 rotates, causing the rotating shaft 430 to rotate, which in turn causes the spline shaft 420 to rotate. Since the spline shaft 420 is engaged with the spline sleeve 410, and the spline sleeve 410 is coaxially and fixedly connected to the polishing disc 110, when the spline shaft 420 rotates, the polishing disc 110 can rotate, thus achieving… For polishing the pre-formed balls within each loading zone, when the rotating shaft 430 rotates, it drives the driving gear 610 to rotate. According to the gear meshing transmission principle, each driven gear 620 will rotate synchronously in opposite directions, thereby driving the corresponding positioning member 310 to rotate. Since there is friction between the positioning member 310 and the corresponding collar 210, when the positioning member 310 rotates, it drives the collar 210 to rotate. Since there is friction between the collar 210 and each of the carrier discs 220 inside it, it drives each carrier disc 220 to rotate within the loading zone, thereby driving each pre-formed ball to rotate. This further improves the polishing efficiency and polishing effect of the polishing disc 110 on the pre-formed balls.This polishing machine can polish multiple pre-made balls at a time, making it highly efficient for batch polishing of pre-made balls.

[0047] The infrared chalcogenide glass pre-formed microsphere polishing machine provided by this utility model has the following beneficial effects:

[0048] (1) When the spline shaft 420 in the drive mechanism 400 is separated from the spline sleeve 410, each of the positioning elements 310 in each positioning mechanism 300 is separated from the corresponding collar 210, thereby facilitating the sequential loading and unloading of each collar 210, each of the carrier disks 220 and each of the pre-made small balls onto the polishing disk 110. When the spline shaft 420 in the drive mechanism 400 is engaged with the spline sleeve 410, each of the positioning elements 310 in each positioning mechanism 300 abuts against the corresponding collar 210, thereby facilitating the polishing of the pre-made small balls.

[0049] (2) When the rotating shaft 430 rotates, it will drive the driving gear 610 to rotate. According to the gear meshing transmission principle, each driven gear 620 will rotate synchronously in opposite directions, thereby driving the corresponding positioning member 310 to rotate. Since there is friction between the positioning member 310 and the corresponding collar 210, when the positioning member 310 rotates, it will drive the collar 210 to rotate. Since there is friction between the collar 210 and each of the carriers 220 inside it, it will drive each of the carriers 220 to rotate in the loading area, thereby driving each of the pre-made small balls to rotate, thereby further improving the polishing efficiency and polishing effect of the polishing disc 110 on the pre-made small balls.

[0050] (3) This polishing machine can polish multiple pre-made balls at a time, and has high efficiency when polishing pre-made balls in batches.
