Description

TECHNICAL FIELD

[0001] The present application relates to the field of glass bead polishing, and particularly discloses a rapid grinding and polishing device for highway tunnel reflective glass beads. BACKGROUND

[0002] The reflective glass beads for highway tunnels are the core components of traffic safety facilities, and the surface quality thereof directly determines the reflective performance. The glass beads need to refract and reflect light through the surface layer to achieve the night reflective effect. Therefore, the surface smoothness, sphericity and reflective performance of the reflective glass beads for highway tunnels are required to be extremely high. Therefore, the surface of the glass beads needs to be ground and polished during the manufacturing process of the glass beads.

[0003] In the prior art, a single-layer flat polishing system is generally used to rapidly polish the glass beads. However, this polishing system still has some deficiencies in daily use. During the polishing operation, the glass beads are only subjected to surface treatment by the friction coefficient generated by the rotation of a single polishing disc, which leads to a negative correlation between the polishing efficiency and the surface uniformity. When the rotation speed is increased to a critical value, the centrifugal aggregation phenomenon occurs. Moreover, under the action of the single polishing disc, the glass beads only make spiral motion along the tangent direction, which leads to over-polishing of the specific area of the bead surface (such as the bottom of the contact polishing disc) and insufficient polishing of other areas, thereby affecting the consistency of the glass beads during grinding and polishing and reducing the grinding and polishing precision of the glass beads. SUMMARY

[0004] The present application aims to provide a rapid grinding and polishing device for highway tunnel reflective glass beads to solve the above technical problems in the prior art.

[0005] Specifically, the present application is implemented by the following technical solutions.

[0006] A rapid grinding and polishing device for highway tunnel reflective glass beads comprises a polishing bin, a polishing group disc is embedded in the inside lower part of the polishing bin, and the polishing group disc comprises a first polishing disc and a second annular polishing disc which are coaxially sleeved in sequence from the inside to the outside, the upper polishing surface of the second annular polishing disc is inclined upward in a direction gradually away from the first polishing disc, and a collecting disc is rotationally connected between the first polishing disc and the second annular polishing disc.

[0007] A driving device is arranged at the bottom of the polishing bin to drive the first polishing disc and the second annular polishing disc to rotate in opposite directions, so as to perform multi-stage reverse polishing on the glass beads in the polishing bin through the reverse rotation of the first polishing disc and the second annular polishing disc.

[0008] It should be noted that, in order to solve the technical problem of inconsistent polishing efficiency and surface treatment uniformity of glass beads with a single polishing surface in the prior art, this technical solution sets a first polishing disc and a second annular polishing disc rotating in opposite directions, and makes the upper polishing surface of the second annular polishing disc tilt upward in the direction away from the first sub-disc, thereby constructing a dynamic composite polishing field for the glass beads in the polishing chamber. Specifically, when polishing, the first polishing disc and the second annular polishing disc rotate in opposite directions to polish each other, so as to force the glass beads and the polishing material to be periodically subjected to the influence of the first polishing disc and the second polishing disc when moving in the polishing chamber. The reverse shear force of the two annular polishing discs allows the glass beads to be polished quickly. At the same time, under the action of the reverse shear force, the glass beads can produce a rotation in the opposite direction of the initial spin. Combined with the inclined polishing surface on the upper part of the second annular polishing disc, the glass beads present a three-dimensional disordered rolling during the overall movement. This is different from the unidirectional tangential friction of traditional single-layer polishing discs. The contact angle and frequency of each area of ​​the glass bead surface with the polishing surface and polishing material gradually tend to be uniform, thereby achieving isotropic polishing of the sphere surface, ensuring the consistency of the glass bead surface grinding and polishing, and improving the grinding and polishing accuracy of the glass beads;

[0009] Furthermore, the inclined polishing surface design of the second annular polishing disc allows the glass beads to gradually swing outward during polishing and grinding through the coupling effect of centrifugal force and the inclined surface force, thereby avoiding the "centrifugal clustering" phenomenon during high-speed polishing, and the collecting disc located between the two polishing sub-disks can realize the dynamic transition of glass beads between different polishing areas (such as the first polishing disc and the second annular polishing disc) through rotation cooperation (that is, the collecting disc will not rotate with the first polishing disc and the second annular polishing disc, and it is always in a stationary state), so as to form a transition buffer zone, reduce the probability of glass beads colliding with each other, weaken the collision force between glass beads, and reduce the collision and breakage of glass beads.

[0010] Preferably, an array of friction bevel grooves is provided on the upper polishing surfaces of both the first polishing disc and the second annular polishing disc. The friction bevel groove design further enhances the polishing friction between the first and second annular polishing discs and the glass beads, forcing the glass beads to grind and polish more quickly. The friction bevel groove design also accelerates the circulation of the polishing material. Specifically, the flow channels created by the friction bevel grooves accelerate the circulation of the polishing material at the contact point between the polishing surface and the glass beads, achieving dynamic renewal of the polishing material and further improving the uniformity and consistency of the glass bead polishing.

[0011] Further, the driving device comprises a motor and a gear set, the motor is installed on the top of the polishing bin at the lower part of the polishing bin, the gear set comprises a driving gear sleeved on the output end of the motor, four transmission gears are installed around the driving gear and engaged with the driving gear, a gear ring is sleeved around the transmission gears and engaged with the transmission gears, and the gear ring is connected with the second annular polishing disc.

[0012] The motor and the gear set are provided, high-precision reverse speed control of the first polishing disc and the second annular polishing disc is realized, specifically, the driving gear is directly connected with the motor to drive the first polishing disc to rotate clockwise, the four circumferentially distributed transmission gears split the power to the gear ring and reverse the torque direction, so that the second annular polishing disc can rotate counterclockwise.

[0013] Specifically, the surface of the collecting disc is provided with a plurality of discharge openings, and the periphery of each discharge opening is respectively inclined and transitioned to the first polishing disc and the second polishing disc, and a discharge electronic valve is further arranged in the discharge opening.

[0014] The discharge opening provided on the surface of the collecting disc and the edge inclined and transitioned to the double discs are designed, and the discharge electronic valve inside is matched, when the glass beads move to the collecting disc area after being polished by the first polishing disc and the second annular polishing disc, the glass beads are quickly and unobstructively slid into the discharge opening through the flow guiding effect of the inclined edge.

[0015] Further preferably, the bottom of the plurality of discharge openings is connected with the spiral discharge cavity in the bin, the inner diameter of the spiral discharge cavity is larger than the outer diameter of the glass beads, a friction polishing pad is attached to the inner wall of the spiral discharge cavity along the length direction of the spiral discharge cavity, grooves are staggered arranged on the inner wall of the spiral discharge cavity, and pulse nozzles are installed in the grooves, the nozzle end of the pulse nozzles faces the spiral discharge cavity and is used for spraying pulse airflow.

[0016] The spiral discharge cavity and the pulse nozzle are cooperatively designed, secondary polishing defect elimination and surface cleaning are realized during the falling process of the glass beads, compared with the prior art, the above-mentioned scheme design is realized, the glass beads complete the composite treatment of "friction polishing-posture adjustment-impurity cleaning" during the spiral falling process, and the use effect of the device is further improved.

[0017] Furthermore, a collection cavity for communicating with the spiral blanking cavity is provided at the lower interior of the machine warehouse. A quality inspection area with a gradually smooth transition is provided at the bottom end of the spiral blanking cavity near the collection cavity. Several visual sensors are installed in the quality inspection area. The visual sensors are signal-connected to the quality inspection terminal installed outside the machine warehouse. The visual sensors are used to dynamically collect external visual information of the glass beads rolling into the quality inspection area, and transmit it to the quality inspection terminal in real time. The quality inspection terminal obtains quality data after calculating and processing the external visual information of the glass beads, and stores and displays it.

[0018] In the above scheme, after the glass beads are further polished and cleaned by the spiral blanking cavity, they will continue to roll and eventually enter the aggregate cavity. The present scheme cleverly provides a quality inspection area with a gradually smooth transition at the bottom end of the spiral blanking cavity near the aggregate cavity, and installs several visual sensors in this area to dynamically collect the external visual information of the glass beads rolling in through the visual sensors, and transmit it to the quality inspection terminal in real time. The quality inspection terminal processes this information based on a preset algorithm model to obtain the quality data of the glass beads, and generates a quality inspection report for storage and display, so that the operator can intuitively understand the quality status of the polished and ground glass beads, thereby realizing real-time, dynamic detection and data traceability of the glass beads quality.

[0019] More preferably, a buffer rubber pad is attached to the inner wall of the collecting cavity, and the collecting cavity is connected to the outside through a discharge pipe.

[0020] The setting of the buffer rubber pad can effectively absorb the impact energy of the falling beads through elastic buffering when the glass beads roll into the aggregate cavity through the quality inspection area, avoiding surface scratches or bumps caused by hard contact, and ensuring that the surface quality of the polished glass beads is not damaged again;

[0021] At the same time, the aggregate cavity is connected to the outside world through the discharge pipe, forming a smooth material discharge channel, supporting the glass beads to enter the subsequent process by free fall or low-speed transportation, so as to avoid material accumulation in the aggregate cavity affecting process continuity.

[0022] Specifically, a feeding pipe connected to the polishing chamber is provided on the upper part of the polishing chamber, and the feeding pipe is used for feeding glass beads and polishing materials.

[0023] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0024] 1. The present invention provides a first polishing disc and a second annular polishing disc rotating in opposite directions, and makes the upper polishing surface of the second annular polishing disc tilt upward in a direction away from the first sub-disc, thereby constructing a dynamic composite polishing field for glass beads in the polishing chamber. Specifically, the first polishing disc and the second annular polishing disc rotate in opposite directions to each other during polishing, so that the glass beads and the polishing material are periodically subjected to reverse shearing forces from the first polishing disc and the second annular polishing disc when moving in the polishing chamber, thereby quickly polishing the glass beads. At the same time, under the action of the reverse shearing force, the glass beads can generate a rotation opposite to the initial spin direction, and combined with the inclined polishing surface of the second annular polishing disc, the glass beads present three-dimensional disordered rolling during the overall movement, thereby distinguishing it from the unidirectional tangential friction of the traditional single-layer polishing disc, making the contact angles and frequencies of various regions of the glass bead surface with the polishing surface and the polishing material gradually uniform, thereby achieving isotropic polishing of the sphere surface, ensuring the consistency of the grinding and polishing of the glass bead surface, and improving the grinding and polishing accuracy of the glass beads;

[0025] 2. The present invention further features an inclined polishing surface on the second annular polishing disc. This allows the glass beads to gradually swing outward during polishing through the coupling of centrifugal force and the inclined surface force component, thereby avoiding the "centrifugal bunching" phenomenon during high-speed polishing. Furthermore, the collecting disc located between the two polishing discs rotates (i.e., the collecting disc does not rotate with the first and second annular polishing discs and remains stationary), enabling dynamic transition of the glass beads between different polishing areas (e.g., the first and second annular polishing discs) to form a transition buffer zone, thereby reducing the probability of collision between the glass beads and weakening the collision force between the glass beads, thereby minimizing collision and breakage of the glass beads.

[0026] 3. The present invention provides friction bevel grooves on the upper polishing surfaces of the first and second annular polishing discs, thereby further enhancing the polishing friction between the first and second annular polishing discs and the glass beads, forcing the glass beads to grind and polish more quickly. Simultaneously, the design of the friction bevel grooves accelerates the circulation of the polishing material. Specifically, the guide channels created by the friction bevel grooves accelerate the circulation of the polishing material at the contact point between the polishing surface and the glass beads, achieving dynamic renewal of the polishing material and further improving the uniformity and consistency of the glass bead polishing.

[0027] 4. The present invention further realizes the dual coordinated optimization of secondary polishing defect elimination and surface cleaning during the falling process of the glass beads through the coordinated design of the spiral blanking cavity and the pulse nozzle, and realizes the composite treatment of "friction polishing-posture adjustment-impurity cleaning" of the glass beads during the spiral falling process, further improving the use effect of the device.

[0034] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the examples and accompanying drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0035] Example

[0036] See also Figure 1 As shown, this embodiment discloses a device for rapid grinding and polishing of reflective glass beads and quality inspection in highway tunnels, comprising a polishing chamber 1 having a hollow interior, with a polishing disc assembly embedded in the lower portion of the polishing chamber 1. The polishing disc assembly comprises a first polishing disc 11 and a second annular polishing disc 12 coaxially sleeved from the inside out. The upper polishing surface of the second annular polishing disc 12 is inclined upwardly and gradually away from the first polishing disc 11. A collecting disc 13 is rotatably disposed between the first polishing disc 11 and the second annular polishing disc 12.

[0037] The bottom of the polishing bin 1 is provided with a driving device for driving the first polishing disc 11 and the second annular polishing disc 12 to rotate reversely, so that the glass beads in the polishing bin 1 are subjected to multi-stage reverse polishing through the reverse rotation of the first polishing disc 11 and the second annular polishing disc 12.

[0038] It should be noted that, in order to solve the technical problem of the inconsistency of polishing efficiency and surface treatment uniformity of glass beads by a single polishing surface in the prior art, the present technical solution sets the first polishing disc 11 and the second annular polishing disc 12 to rotate reversely, and makes the upper polishing surface of the second annular polishing disc 12 tilt upward in the direction away from the first sub-disc, thereby constructing a dynamic composite polishing field for glass beads in the polishing bin 1. Specifically, when the first polishing disc 11 and the second annular polishing disc 12 are polishing, they rotate reversely to each other, so that the glass beads and the polishing material are periodically subjected to reverse shearing force from the first polishing disc 11 and the second annular polishing disc 12 when moving in the polishing bin 1, thereby rapidly polishing the glass beads. At the same time, the glass beads generate a rotation in the opposite direction of the initial self-rotation under the action of the reverse shearing force, and the tilt polishing surface of the second annular polishing disc 12 makes the glass beads present a three-dimensional disordered rolling in the overall movement process. In this way, it is different from the one-way tangent friction of the traditional single-layer polishing disc, so that the contact angle and frequency of each region of the glass bead surface with the polishing surface and the polishing material gradually tend to be uniform, thereby realizing isotropic polishing of the surface of the sphere, ensuring the consistency of the surface grinding and polishing of the glass beads, and improving the grinding and polishing precision of the glass beads.

[0039] Meanwhile, it is further shown in Figure 1 that the tilt polishing surface of the second annular polishing disc 12 is designed to guide the glass beads to gradually present an outward swinging during polishing and grinding through the coupling effect of centrifugal force and slope component force, thereby avoiding the "centrifugal aggregation" phenomenon during high-speed polishing. The collecting disc 13 located between the two polishing sub-discs can realize the dynamic transition of the glass beads between different polishing regions (such as the first polishing disc 11 and the second annular polishing disc 12) through rotation cooperation (that is, the collecting disc 13 does not rotate with the first polishing disc 11 and the second annular polishing disc 12, and it is always in a stationary state), so as to form a transition buffer zone, reduce the probability of collision between glass beads and weaken the collision force between glass beads, and reduce the breakage of glass beads due to collision.

[0040] Exemplarily, when the driving device is started, it drives the first polishing disc 11 to rotate clockwise, and the second annular polishing disc 12 to rotate counterclockwise, so that the glass beads on the first polishing disc 11 in the polishing bin 1 are first subjected to the centrifugal force to diffuse outward, and gradually move to the second annular polishing disc 12 through the collecting disc 13. Due to the reverse rotation of the second annular polishing disc 12, a reverse shear force is suddenly applied to the glass beads, forcing the glass beads to spin reversely. At the same time, due to the inclination of the upper polishing surface of the second annular polishing disc 12, a radial velocity gradient field is formed on the glass beads, so that the glass beads produce complex three-dimensional random rolling on the second polishing disc, and the contact probability of each point on the surface of the glass beads with the polishing surface tends to be balanced, thereby achieving uniform polishing of the surface of the glass beads.

[0041] Preferably, referring to Figure 2 , friction inclined grooves 17 are arranged on the upper polishing surfaces of the first polishing disc 11 and the second annular polishing disc 12.

[0042] Through the design of the friction inclined grooves 17, the polishing friction between the first polishing disc 11 and the second annular polishing disc 12 and the glass beads can be further improved, forcing the glass beads to grind and polish more quickly. At the same time, through the design of the friction inclined grooves 17, the circulation of the polishing material is accelerated, that is, the circulation process of the polishing material at the contact part between the polishing surface and the glass beads is accelerated by the flow guide channel generated by the friction inclined grooves 17, the dynamic updating of the polishing material is realized, and the uniformity and consistency of the glass bead polishing are further improved.

[0043] Further, as shown in Figure 2 , the inclined directions of the friction inclined grooves 17 on the first polishing disc 11 and the second annular polishing disc 12 are opposite, so that the grinding and polishing force received by the glass beads during grinding and polishing is more complex and variable, and the contact point change frequency between the glass bead surface and the polishing surface is higher compared with the plane polishing, thereby accelerating the rapid grinding and falling of burrs and protrusions on the surface of the glass beads.

[0044] Further, as shown in Figure 3 , the driving device includes a motor 14 and a gear set. The motor 14 is installed on the top of the bin 2 at the lower part of the polishing bin 1. The gear set includes a driving gear 151 sleeved on the output end of the motor 14. A transmission gear 152 is installed around the driving gear 151 and engaged with the driving gear 151. The transmission gear 152 is connected with the collecting disc 13 and the bin 2 through the rotationally arranged gear rods. A gear ring 153 is sleeved around the transmission gear 152 and engaged with the transmission gear 152. The gear ring 153 is connected with the second annular polishing disc 12.

[0045] This solution achieves high-precision reverse speed control of the first polishing plate 11 and the second annular polishing plate 12 through the setting of the motor 14 and the gear set. Specifically, the driving gear 151 is directly connected to the motor 14 to drive the first polishing plate 11 to rotate clockwise, and the four circumferentially evenly distributed transmission gears 152 divert power to the ring gear 153 and reverse the torque direction, so that the second annular polishing plate 12 can rotate counterclockwise.

[0046] Specifically, a plurality of drop openings 131 are provided on the surface of the collecting plate 13 , and the edges of each drop opening 131 are inclined to transition with the first polishing plate 11 and the second polishing plate, respectively. An electronic drop valve 132 is also provided inside the drop opening 131 .

[0047] This solution uses a blanking port 131 opened on the surface of the collecting tray 13 and an edge design that transitions obliquely with the double trays, in conjunction with an internal blanking electronic valve 132. When the glass beads move to the collecting tray 13 area after reverse polishing by the first polishing disk 11 and the second annular polishing disk 12, the blanking electronic valve 132 is opened, and the guiding effect of the inclined edge facilitates the glass beads to slide quickly and unhindered into the blanking port 131.

[0048] More preferably, Figure 1 As shown in the figure, the bottoms of the multiple blanking ports 131 are connected to the spiral blanking cavity 21 in the machine chamber 2, and the inner diameter of the spiral blanking cavity 21 is larger than the outer diameter of the glass beads. The inner wall of the spiral blanking cavity 21 is provided with a friction polishing pad along its length direction, and grooves 22 are staggered on the inner wall of the spiral blanking cavity 21. A pulse nozzle 23 is installed in the groove 22, and the nozzle end of the pulse nozzle 23 faces the spiral blanking cavity 21 for ejecting pulse airflow.

[0049] It should be understood that the pulse nozzle 23 is connected to the external air source through a pipeline passing through the machine chamber 2, and the friction polishing pad is attached with an adsorption layer. The adsorption layer is mainly used to capture fine impurities suspended in the spiral blanking cavity 21 through physical adsorption or electrostatic adsorption effects after the pulse nozzle 23 blows air to remove dust particles on the surface of the glass beads. The adsorption layer is not shown in the figure.

[0050] This embodiment realizes the dual coordinated optimization of secondary polishing defect elimination and surface cleaning during the falling process of the glass beads through the coordinated design of the spiral blanking cavity 21 and the pulse nozzle 23. Compared with the existing technology, it further realizes the composite processing of "friction polishing-posture adjustment-impurity cleaning" of the glass beads during the spiral falling process through the above-mentioned design scheme, further improving the use effect of the device.

[0051] Specifically, when the glass beads enter the spiral blanking cavity 21 through the blanking port 131 on the collecting tray 13, since the inner diameter of the cavity is larger than the outer diameter of the beads, it is convenient for the glass beads to roll smoothly in the spiral blanking cavity 21. At the same time, the pulse nozzle 23 in the groove 22 on the inner wall of the cavity is connected to the external air source (such as an air compressor, an air storage tank or a nitrogen cylinder group, which can be selected according to actual needs) through a pipeline, and sprays high-speed air flow into the cavity in an interval pulse manner, thereby periodically impacting the glass beads laterally through the air flow, so that the glass beads are axially turned under the action of the lateral component force. The glass beads rotate and collide with the inner wall of the spiral blanking channel 21, thereby slowing down the moving speed of the glass beads in the spiral blanking channel 21, and then each area of ​​the glass bead surface contacts the polishing pad evenly, so as to further remove the polishing defects on the surface of the glass beads and improve the polishing accuracy. At the same time, the high-speed airflow impacts and strips and blows away the polishing material particles and dust remaining on the surface. The polishing material particles and dust after blowing away can adhere to the adsorption layer, so as to achieve efficient removal of residual abrasives after polishing and precise control of surface cleanliness, and solve the problems of impurity residue and uneven polishing in the traditional blanking process.

[0052] As a preference, see Figure 4 In the above embodiment, the pulse nozzle 23 is movably installed in the groove 22. Further, as shown in the figure, a ball joint 24 connected to the pulse nozzle 23 is provided inside the groove 22, that is, the pulse nozzle 23 and the groove 22 are spherically connected. Therefore, when the pulse nozzle 23 ejects airflow, the dynamic angle change is achieved through the back-impact of the airflow, so that the airflow can cover the surface of the glass beads in all directions, generating airflow impact forces in different directions on the glass beads, thereby enhancing the tumbling effect of the glass beads in the spiral blanking cavity 21, and effectively removing residual polishing material particles and dust from every corner of the glass bead surface. Compared with the pulse nozzle 23 with a fixed angle, it can further improve the cleaning effect and improve the quality of surface polishing.

[0053] In order to prevent the glass beads from damaging the pulse nozzle 23 when rolling and falling in the spiral blanking cavity 21 and to prevent the pulse nozzle 23 from being blocked, this embodiment further provides a filter screen flush with the spiral blanking cavity 21 at the opening of the groove 22.

[0054] Furthermore, a collecting cavity 27 for communicating with the spiral blanking cavity 21 is provided at the lower part of the interior of the machine chamber 2. A quality inspection area 25 with a gradually smooth transition is provided at the bottom end of the spiral blanking cavity 21 near the collecting cavity 27. Several visual sensors 26 are installed in the quality inspection area 25. The visual sensors 26 are signal-connected to the quality inspection terminal installed outside the machine chamber 2. The visual sensors 26 are used to dynamically collect external visual information of the glass beads rolling into the quality inspection area 25, and transmit it to the quality inspection terminal in real time. The quality inspection terminal obtains quality data after calculating and processing the external visual information of the glass beads, and stores and displays it.

[0055] During implementation, after the glass beads are further polished and cleaned by the spiral blanking channel 21, they will continue to roll and eventually enter the aggregate cavity 27. This solution cleverly provides a gradually transitioning quality inspection area 25 at the bottom end of the spiral blanking channel 21 near the aggregate cavity 27, and installs a number of visual sensors 26 in this area to dynamically collect external visual information of the glass beads rolling in through the visual sensors 26, and transmit it to the quality inspection terminal in real time. The quality inspection terminal processes this information based on a preset algorithm model to obtain the quality data of the glass beads, and generates a quality inspection report for storage and display, so that the operator can intuitively understand the quality status of the polished and ground glass beads, thereby realizing real-time, dynamic detection and data traceability of the glass beads quality.

[0056] Exemplarily, the quality inspection area 25 utilizes the conversion of gravitational potential energy to naturally decay the rolling speed of the glass beads from high speed to low speed to eliminate motion blur. At the same time, five groups of high-speed visual sensors 26 with different shooting angles are spaced along the length of the inspection area to capture the RGB image data of the glass beads through the high-speed visual sensors 26, and transmit it to the quality inspection terminal in real time through the communication port or Bluetooth module. The quality inspection terminal is an industrial control processing computer, which uses a preset algorithm model to calculate and process the RGB image data to generate surface quality inspection data of the glass beads, including the surface smoothness, sphericity and crack characteristics of the beads, and displays it through the display panel and stores it in the storage device, thereby facilitating subsequent data traceability.

[0057] It should be further supplemented that the quality detection module of the technical solution focuses on online yield rate statistics and process feedback. Its essence is to realize dynamic quality detection of the glass beads during the rolling process through the structural design of the quality detection area 25. The visual sensor 26, the detection terminal, and the preset algorithm and related model are all existing public technologies, and the person skilled in the art can learn from relevant public channels (for example, the visual sensor 26 can adopt a high-precision industrial camera, which has the characteristics of high resolution and high frame rate, and can quickly and clearly capture the external visual information of the glass beads. The detection terminal can adopt an industrial tablet computer, and the preset algorithm model can adopt a convolutional neural network algorithm). Therefore, the present application does not make specific description and further limitation here, and it is not within the protection scope of the present application.

[0058] Further preferably, in the embodiment, the inner wall of the aggregate cavity 27 is attached with a buffer rubber pad (not shown in the figure), and the aggregate cavity 27 is connected with the outside through the discharge pipe 28.

[0059] In the embodiment, through the setting of the buffer rubber pad, when the glass beads roll into the aggregate cavity 27 through the quality detection area 25, the impact energy of the falling beads can be effectively absorbed through the elastic buffering effect, so as to avoid surface scratches or bump damage caused by hard contact, and ensure that the surface quality of the polished qualified glass beads is not damaged again.

[0060] At the same time, the aggregate cavity 27 is connected with the outside through the discharge pipe 28, forming a smooth material discharge channel, supporting the glass beads to enter the subsequent process (such as packaging, sorting) in the form of free fall or low-speed conveying (such as cooperating with a negative pressure adsorption device), so as to avoid the accumulation of materials in the aggregate cavity 27 affecting the process continuity.

[0061] Specifically, as shown in Figure 1 The polishing bin 1 further comprises a feeding pipe 16 connected with the polishing bin 1 at the upper part, and the feeding pipe 16 is used for feeding glass beads and polishing material.
