Description

Technical Field

[0001] This application relates to the field of polishing machines, and particularly to a double-sided planar polishing machine with automatic blanking. Background Art

[0002] A double-sided polishing machine is a high-precision and high-efficiency polishing processing equipment for the double-sided polishing of semiconductor silicon wafers, magnetic materials, sapphires, optical glass, metal materials and other hard and brittle materials. The processing accuracy of the double-sided polishing machine affects the performance of the processed materials.

[0003] Traditional double-sided polishing machines often use two grinding disks, upper and lower, with a planetary gear train in the middle for carrying the glass slide. The upper grinding disk is generally driven by a hydraulic cylinder. The hydraulic cylinder drives the upper grinding disk to press down on the glass slide and polish the polishing material. When the polishing of the glass slide is completed, since the glass slide is thin, it is not easy for the operator to remove the glass slide from the planetary gear train, which is not convenient for the blanking of the glass slide. Summary of the Invention

[0004] In order to improve the problem of difficult blanking of glass slides, this application provides a double-sided planar polishing machine with automatic blanking.

[0005] The double-sided planar polishing machine with automatic blanking provided by this application adopts the following technical solutions:

[0006] A double-sided planar polishing machine with automatic blanking includes a support cylinder, a lower grinding disk, a planetary gear for placing a glass slide, and a driving motor for driving the planetary gear to rotate. The lower grinding disk is arranged at the end of the support cylinder. A rack meshing with the planetary gear is provided at the edge of the lower grinding disk. A rotating cylinder is coaxially arranged on the output shaft of the driving motor. The rotating cylinder passes through the lower grinding disk and is rotatably arranged with the lower grinding disk. A first gear is coaxially arranged at one end of the rotating cylinder passing through the lower grinding disk. The first gear meshes with the planetary gear. A transport cylinder is rotatably arranged in the rotating cylinder. A rotating motor for driving the transport cylinder to rotate is arranged in the support cylinder. The angular velocity of the planetary gear around the axis of the transport cylinder is the same as the angular velocity of the transport cylinder. A grasping assembly for adsorbing and moving the glass slide is rotatably arranged in the transport cylinder. A grasping hole is provided on the transport cylinder. A laser sensor for positioning the glass slide and controlling the on-off of the rotating motor and the driving motor is provided on the transport cylinder. A blanking conveying assembly for receiving and transporting the glass slide is arranged in the transport cylinder.

[0007] By adopting the above technical solution, after the polishing of the glass slide is completed, while the planetary gear is driven by the driving motor to rotate on the lower grinding disc, the planetary gear rotates itself, and the rotating motor drives the transport cylinder to rotate together with the planetary gear. When the glass slide on the planetary gear moves to the grasping hole position, the laser sensor controls the rotating motor and the driving motor to cut off the power supply, the planetary gear stops rotating, the grasping component extends out of the grasping hole to grasp the glass slide, and then the grasping component contracts into the transport cylinder and is placed on the blanking conveying component, and then the glass slide is transported out of the transport cylinder through the blanking conveying component, so as to realize taking the glass slide off the planetary gear and improve the convenience of blanking the glass slide.

[0008] In a specific feasible embodiment, the grasping component includes a hydraulic cylinder, a grasping rod and a suction attachment. The grasping rod is rotatably arranged in the transport cylinder. The cylinder body of the hydraulic cylinder is rotatably arranged with the transport cylinder. The piston rod end of the hydraulic cylinder is rotatably arranged with the grasping rod. One end of the grasping rod is bent to form a grasping head, and the suction attachment is located on the grasping head. The hydraulic cylinder drives the grasping rod to make the suction attachment rotate onto the glass slide.

[0009] By adopting the above technical solution, when grasping the glass slide, the hydraulic cylinder extends, the hydraulic cylinder pushes the grasping rod to rotate, so that the grasping rod extends out of the grasping hole. As the grasping rod continuously extends, finally the suction attachment of the grasping head is placed on the glass slide, and then the suction attachment adsorbs the glass slide. Then the hydraulic cylinder contracts and retracts into the transport cylinder through the grasping rod, so as to realize taking the glass slide off the planetary gear.

[0010] In a specific feasible embodiment, the suction attachment includes a suction cup, a vacuum generator and a hose. The suction cup is located on the grasping head. The vacuum generator is located on the transport cylinder. The vacuum generator is communicated with the suction cup through the hose.

[0011] By adopting the above technical solution, when adsorbing the glass slide, the suction cup falls onto the glass slide along with the grasping head, and then the vacuum generator is driven. The vacuum generator drives the suction cup to be in negative pressure through the hose, so that the suction cup adsorbs the glass slide.

[0012] In a specific feasible embodiment, the grasping head is connected by two connecting rods. A connecting cylinder is arranged on one of the connecting rods, and a limiting block is arranged on the other connecting rod. The connecting rod together with the other connecting rod is inserted into the connecting cylinder and is slidably arranged with the connecting cylinder. A limiting ring for restricting the limiting block from sliding out is arranged on the connecting cylinder, and a buffer spring for being squeezed by the other connecting rod is arranged in the connecting cylinder.

[0013] By adopting the above technical solution, when the gripping head drives the suction cup to move to the glass slide, relative sliding occurs between the two connecting rods through the support spring, and the connecting rod slides in the connecting cylinder through the limiting block and the limiting ring, effectively preventing the glass slide from being crushed due to excessive pressure of the gripping head.

[0014] In a specific feasible implementation, the blanking and conveying assembly includes a conveyor belt, a driven wheel and a driving wheel. Both the driving wheel and the driven wheel are rotatably arranged in the transportation cylinder through a rotating shaft. The driving wheel and the driven wheel are connected by the conveyor belt. The conveyor belt is provided with a placement box for placing the glass slide, and the gripping rod drives the driving wheel to rotate through a connecting member.

[0015] By adopting the above technical solution, when the gripping rod drives the glass slide to move into the transportation cylinder, the gripping rod drives the driving wheel to rotate through the connecting member, and the driving wheel drives the placement box to move through the conveyor belt. When the gripping rod completely retracts into the transportation cylinder, the placement box moves to the lower side of the glass slide, and then the vacuum generator is powered off, and the glass slide falls from the suction cup into the placement box, thus realizing the transfer of the glass slide between gripping and transportation.

[0016] In a specific feasible implementation, the transportation cylinder is provided with a microswitch for the gripping rod to press. The microswitch is used to control the on-off of the vacuum generator. The gripping rod pulls the glass slide to move above the placement box and presses the microswitch, causing the microswitch to power off.

[0017] By adopting the above technical solution, when the gripping rod completely retracts into the transportation cylinder, the gripping rod presses the microswitch, and the microswitch controls the power-off of the vacuum generator, thus making the rotation of the gripping rod and the dropping of the glass slide more synchronous.

[0018] In a specific feasible implementation, the connecting member includes a connecting rod and a driving rod. The rotating shaft passes through the driving rod and is rotatably arranged with the driving rod. One end of the connecting rod is rotatably arranged with the gripping rod, and the other end of the connecting rod is rotatably arranged with the driving rod. Several slots are provided at one end of the driving wheel close to the driving rod, and the slots are evenly arranged along the circumferential direction of the driving wheel. The driving rod is provided with insertion blocks for inserting into the slots.

[0019] By adopting the above technical solution, when the gripping rod retracts into the transportation cylinder, the gripping rod drives the driving rod to rotate around the rotating shaft through the connecting rod. The driving rod drives the driving wheel to rotate through the cooperation of the insertion block and the slot, and the driving wheel drives the placement box to move through the conveyor belt, so that the gripping rod drives the placement box to move, and at the same time improves the synchronization of the cooperation between the gripping and transportation of the glass slide.

[0020] In a specific feasible implementation, the distance from the insertion block to the drive shaft is equal to the distance from the slot to the rotation shaft. The central angle between two adjacent slots is less than the swing amplitude of the drive rod. The insertion block and the drive rod are connected by a drive spring. A drive surface for the insertion block to slide out is provided on the side wall of the slot. The drive rod drives the driving wheel to rotate by pressing the drive surface through the insertion block.

[0021] By adopting the above technical solution, when grasping another glass slide, the hydraulic cylinder extends and drives the grasping rod to extend out of the grasping hole. At this time, the grasping rod drives the drive rod to rotate through the connecting rod. The drive rod drives the insertion block to slide along the drive surface. At this time, the insertion block presses the drive spring and moves in the direction of the drive rod, causing the insertion block to slide out of the slot and slide along the end face of the driving wheel. At this time, relative sliding occurs between the drive rod and the driving wheel. When the grasping rod is about to contract after grasping the glass slide, the insertion block slides into another slot on the driving wheel and is inserted into the slot under the push of the drive spring. At this time, as the grasping rod contracts into the transport cylinder, the grasping rod drives the driving wheel to rotate through the drive rod, and the driving wheel drives the placement box to move through the conveyor belt, thereby realizing continuous grasping and continuous transportation of the glass slide.

[0022] In a specific feasible implementation, a number of placement through-holes are provided on the planetary gear. The number of placement through-holes is evenly arranged along the circumferential direction of the planetary gear. Elastic rings for clamping the glass slide are evenly provided on the side walls of each placement through-hole.

[0023] By adopting the above technical solution, when placing the glass slide into the placement through-hole in the planetary gear, the glass slide is clamped by the elastic ring, improving the stability of the glass slide during polishing and reducing the collision with the planetary gear.

[0024] In a specific feasible implementation, the placement box includes a box body, a baffle and a slide rail. The box body is provided with a discharge port for the glass slide to slide out. The baffle is used to block the discharge port. The slide rail is arranged at the bottom of the box body. The baffle is slidably arranged along the slide rail. A support spring for pulling the baffle to block the discharge port is provided on the slide rail. A feeding plate is provided on the transport cylinder. A guiding surface is provided on the feeding plate. A feeding block is provided on the baffle. The feeding block slides onto the feeding plate along the guiding surface, and the feeding block slides along the feeding plate to open the discharge port.

[0025] By adopting the above technical solution, when the glass slide drops into the placement box, as the grasping rod continuously grasps the glass slide and enters the placement box, the conveyor belt continuously drives the placement box to move downward. When the placement box moves to the feeding plate, the feeding block slides along the guiding surface. As the feeding block continuously slides along the guiding surface, the baffle moves and the discharge port opens. At this time, the supporting spring stretches, and the glass slide falls from the box body into the collection box, so that the glass slide is separated from the transportation cylinder, realizing the collection of the glass slide.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. After the polishing of the glass slide is completed, the driving motor drives the first gear to drive the planetary gear to rotate. The planetary gear rotates while rotating around the first gear, and the transportation cylinder rotates together with the planetary gear. Then, when the glass slide moves to the position pointed by the laser sensor, the planetary gear and the transportation cylinder stop rotating. The grasping component extends out of the grasping hole to grasp the glass slide, and then retracts into the transportation cylinder. Then, the glass slide is transported out through the blanking conveying component in the transportation cylinder, thus realizing the removal of the glass slide and improving the convenience of the glass slide blanking.

[0028] 2. When grasping the glass slide, the grasping rod drives the suction cup to move onto the glass slide, and then the vacuum generator makes the suction cup in a negative pressure state through the hose, so that the suction cup sucks the glass slide, thus realizing the grasping of the glass slide and improving the stability of grasping the glass slide.

[0029] 3. When the grasping rod retracts into the transportation cylinder, the grasping rod drives the driving rod to rotate around the rotation axis through the connecting rod. The driving rod drives the driving wheel to rotate through the cooperation of the slot and the plug. The driving wheel drives the placement box to move through the conveyor belt. When the grasping rod completely retracts into the transportation cylinder, the conveyor belt drives the placement box to move below the glass slide. When the grasping rod extends out of the transportation cylinder, the grasping rod drives the driving rod to rotate in the reverse direction through the connecting rod. The driving rod drives the plug to slide out of the slot along the driving surface, causing relative sliding between the driving rod and the driving wheel. When the grasping rod drives the suction cup to suck the glass slide, the driving rod drives the plug to move to another slot and insert. When the grasping rod retracts into the transportation cylinder, the grasping rod drives the driving wheel to rotate through the connecting rod and the driving rod, thus realizing that the grasping rod drives the conveyor belt to rotate and improving the coordination of the two movements.

Detailed implementation manners

[0043] The following will further elaborate on this application in conjunction with the attached Figure 1-12 drawings for a more detailed description.

[0044] An embodiment of this application discloses a double-sided planar polishing machine with automatic blanking.

[0045] Referring to Figure 1 、 Figure 2 and Figure 3 , a double-sided planar polishing machine with automatic blanking includes a support cylinder 11, an upper grinding disc 12, a lower grinding disc 13, planetary gears 14, and a driving motor 15. The lower grinding disc 13 is fixedly arranged on the top of the support cylinder 11. There is a support frame on the ground, and a hydraulic lifting system 16 is arranged on the support frame. The upper grinding disc 12 is arranged on the hydraulic lifting system 16. A ring of racks 131 is arranged at the edge of the lower grinding disc 13. A rotating cylinder 17 and a transport cylinder 18 are arranged inside the support cylinder 11. The transport cylinder 18 is inserted into the rotating cylinder 17 and is rotatably arranged with the rotating cylinder 17. The top of the rotating cylinder 17 extends out of the lower grinding disc 13 and is rotatably arranged with the lower grinding disc 13. A first gear 111 is coaxially fixedly arranged at one end of the rotating cylinder 17 extending out of the lower grinding disc 13. The number of planetary gears 14 is three. The three planetary gears 14 are all located between the first gear 111 and the racks 131. The three planetary gears 14 are evenly arranged along the circumferential direction of the first gear 111. Each planetary gear 14 meshes with the racks 131 and the first gear 111. Six placement through-holes 141 are arranged on each planetary gear 14. The six placement through-holes 141 are all evenly arranged along the circumferential direction of the planetary gear 14. An elastic ring 142 for clamping is arranged on the side wall of each placement through-hole 141. The elastic ring 142 is a rubber ring and can also be a ring made of other elastic materials.

[0046] Referring to Figure 1 、 Figure 2 and Figure 3, a support cylinder 11 is provided with a first support plate 112 and a second support plate 113. The axes of the first support plate 112, the second support plate 113 and the support cylinder 11 are collinear. The rotating cylinder 17 extends downward to the first support plate 112 and is slidably arranged with the first support plate 112. The driving motor 15 is fixedly arranged on the first support plate 112. A second gear 171 is coaxially and fixedly arranged on the rotating cylinder 17. The output shaft end of the driving motor 15 is coaxially and fixedly provided with a third gear 151 meshing with the second gear 171. The transport cylinder 18 sequentially penetrates through the first support plate 112 and the second support plate 113. The transport cylinder 18 is rotatably arranged with the first support plate 112 and the second support plate 113 through tapered roller bearings. A fourth gear 181 is coaxially and fixedly arranged on the transport cylinder 18. A rotating motor 114 is fixedly arranged on the second support plate 113. The output shaft end of the rotating motor 114 is coaxially provided with a fifth gear 115 meshing with the fourth gear 181. The top of the transport cylinder 18 extends out of the rotating cylinder 17. Three grasping holes 182 are arranged at the end of the transport cylinder 18 extending out of the rotating cylinder 17. The grasping holes 182 correspond to the planet gears 14 one by one. A grasping assembly 2 for grasping and moving the slide 7 is arranged in the transport cylinder 18. A laser sensor 19 for controlling the on-off power supply of the rotating motor 114 and the driving motor 15 is arranged on the transport cylinder 18. The laser sensor 19 controls the rotating motor 114 and the driving motor 15 through a PLC control circuit. A blanking and conveying assembly 3 for receiving and transporting the slide 7 is arranged in the transport cylinder 18. The grasping assembly 2, the laser sensor 19 and the blanking and conveying assembly 3 all correspond to the planet gears 14 one by one. A collection box 6 for collecting the slides 7 is arranged at the bottom of the transport cylinder 18. Three partition bars 116 are fixedly arranged in the transport cylinder 18. The three partition bars 116 are evenly arranged along the axial direction of the transport cylinder 18. The opposite sides of two adjacent partition bars 116 are parallel. The three grasping holes 182 are respectively located between two adjacent partition bars 116.

[0047] When polishing the slide 7, first place the slides 7 one by one into the placement through holes 141 on the planet gears 14, then use the elastic ring 142 to clamp the slides 7, and then drive the hydraulic cylinder 21 to descend. The hydraulic cylinder 21 drives the upper grinding disc 12 to descend and abut against the slide 7, and at the same time makes the slide 7 abut against the lower grinding disc 13. Then the driving motor 15 drives the rotating cylinder 17 to rotate. The rotating cylinder 17 drives the planet gear 14 to rotate around the first gear 111 and at the same time generates self-rotation, so as to realize the polishing of the upper and lower surfaces of the slide 7. Polishing liquid needs to be sprayed during polishing.

[0048] After the polishing is completed, the hydraulic cylinder 21 drives the upper grinding disc 12 to rise. Then, the laser sensor 19 is turned on, and the drive motor 15 continues to drive the planetary gear 14 to rotate. Then, the drive rotation motor 114 drives the transport cylinder 18 to rotate at the same angular velocity as the planetary gear 14. In this way, the axis of rotation of the planetary gear 14 and the transport cylinder 18 remain relatively stationary. Then, the planetary gear 14 rotates on its own. When the laser sensor 19 detects that the glass slide 7 has moved to the grasping hole 182 position, at this time, the rotation motor 114 and the drive motor 15 stop rotating. Then, the grasping assembly 2 extends out of the transport cylinder 18 through the grasping hole 182, and then grasps the glass slide 7 on the planetary gear 14. Then, the grasping assembly 2 returns to the transport cylinder 18, and then the glass slide 7 grasped on the grasping assembly 2 is transported out through the blanking conveying assembly 3, so as to realize removing the glass slide 7 from the planetary gear 14 and improve the convenience of blanking the glass slide 7. When blanking the glass slide 7, then the drive motor 15 and the rotation motor 114 continue to rotate to grasp the next glass slide 7 on the planetary gear 14.

[0049] Refer to Figure 4 、 Figure 5 , the blanking conveying assembly 3 includes a driving wheel 31, a driven wheel 32 and a conveyor belt 33. Both ends of the driving wheel 31 and the driven wheel 32 are rotatably arranged through a rotating shaft 34 with a partition strip 116. The conveyor belt 33 bypasses the driving wheel 31 and the driven wheel 32 respectively. A plurality of placement boxes 35 are arranged on the conveyor belt 33. A rubber layer is coated on the inner surface of the placement box 35. There is a gap between the conveyor belt 33, the driving wheel 31 and the partition strip 116.

[0050] Refer to Figure 5 、 Figure 6 and Figure 7, the grasping assembly 2 includes a hydraulic cylinder 21, grasping rods 22 and suction accessories 23. The number of grasping rods 22 is two, and the two grasping rods 22 are respectively located on the oppositely arranged side walls of the two partition bars 116. The grasping rods 22 are rotatably arranged with the partition bars 116 through rotating shafts. Each grasping rod 22 is bent at one end away from the rotating shaft to form a grasping head 24. An intermediate connecting rod 25 is fixedly arranged between the two grasping heads 24. The suction accessory 23 includes a suction cup 231, a hose 232 and a vacuum generator 233. The suction cup 231 is fixedly arranged at the center of the intermediate connecting rod 25. The vacuum generator 233 is arranged on the side wall of the transport cylinder 18. The vacuum generator 233 is communicated with the suction cup 231 through the hose 232. The hydraulic cylinder 21 is located on the side wall of the transport cylinder 18. The cylinder body of the hydraulic cylinder 21 is rotatably arranged with the transport cylinder 18 through a rotating shaft. The piston rod of the hydraulic cylinder 21 is hinged with the grasping rod 22. Each grasping head 24 includes two connecting rods 241. One end of a connecting rod 241 is fixedly provided with a connecting cylinder 234, and the other connecting rod 241 is inserted into the connecting cylinder 234 and is slidably arranged with the connecting cylinder 234. A limiting block 236 is fixedly arranged on the connecting rod 241 inserted into the connecting cylinder 234. A limiting ring 237 for restricting the limiting block 236 from sliding out of the connecting cylinder 234 is arranged on the connecting cylinder 234. A buffer spring 235 is fixedly arranged in the connecting cylinder 234. The other end of the buffer spring 235 is fixedly arranged with the connecting rod 241. The limiting ring 237 and the connecting cylinder 234 are integrally manufactured. A microswitch 26 is arranged on the partition bar 116. The microswitch 26 is electrically connected with the vacuum generator 233. The microswitch 26 controls the on-off of the vacuum generator 233.

[0051] When grasping the glass slide 7, the hydraulic cylinder 21 is driven to extend. The hydraulic cylinder 21 pushes the grasping rod 22 to rotate out of the grasping hole 182. The grasping rod 22 drives the suction cup 231 to rotate. As the hydraulic cylinder 21 continuously extends, the grasping rod 22 drives the suction cup 231 to rotate onto the glass slide 7. Then the vacuum generator 233 is started. The vacuum generator 233 sucks the glass slide 7 through the hose 232 by the suction cup 231. Then the hydraulic cylinder 21 contracts, and the hydraulic cylinder 21 drives the grasping rod 22 to contract into the transport cylinder 18, thereby realizing the grasping of the glass slide 7.

[0052] When the grasping rod 22 drives the suction cup 231 to rotate onto the glass slide 7, the grasping head 24 pushes the suction cup 231 to press the glass slide 7 by squeezing the buffer spring 235. At this time, the connecting rod 241 slides in the connecting cylinder 234. Through the buffering action of the buffer spring 235, it effectively avoids crushing the glass slide 7 when the suction cup 231 rotates onto the glass slide 7.

[0053] Refer to Figure 8 、 Figure 9, the driving wheel 31 is connected to each grasping rod 22 through a connecting member 4. The connecting member 4 includes a connecting rod 41 and a driving rod 42. The driving rod 42 is rotatably arranged on the rotating shaft 34. One end of the driving rod 42 extends downward. The connecting rod 41 is hinged to the downward extending end of the driving rod 42. The end of the connecting rod 41 away from the driving rod 42 is hinged to the grasping rod 22. Several slots 43 are provided on the end face of the driving wheel 31. Preferably, the number of slots 43 is four, and the four slots 43 are evenly arranged along the axis of the driving wheel 31. An insertion block 44 for inserting into the slot 43 is provided on the driving rod 42. A driving spring 45 is arranged between the insertion block 44 and the driving rod 42. One end of the driving spring 45 is fixedly arranged with the insertion block 44, and the other end of the driving spring 45 is fixedly arranged with the driving rod 42. A driving surface 46 for the insertion block 44 to slide out is provided in each slot 43. The driving surface 46 inclines from the end wall of the driving wheel 31 towards the bottom wall of the slot 43. The radian of the driving surface 46 is adapted to the movement track of the insertion block 44. The swinging angle of the driving rod 42 is greater than the central angle between two adjacent slots 43. When the hydraulic cylinder 21 pushes the grasping rod 22 to extend out of the transportation cylinder 18, the insertion block 44 slides out of the slot 43 along the driving surface 46 and slides along the end face of the driving wheel 31 towards the next slot 43. At this time, the driving wheel 31 remains stationary due to the frictional force between the rotating shaft 34 and the partition strip 116. When the grasping rod 22 drives the suction cup 231 to move to the glass slide 7, the insertion block 44 slides to the position of the next slot 43. The distance between two adjacent placement boxes 35 is less than the distance that the conveyor belt 33 moves each time. When the grasping rod 22 completely retracts into the transportation cylinder 18, the suction cup 231 adsorbs the glass slide 7 in front of two placement boxes 35.

[0054] When the hydraulic cylinder 21 drives the grasping rod 22 to extend out of the transportation cylinder 18, the grasping rod 22 drives the driving rod 42 to rotate towards the grasping hole 182 through the connecting rod 41. The insertion block 44 on the driving rod 42 slides along the driving surface 46. At this time, the driving spring 45 contracts, and the insertion block 44 moves towards the driving rod 42. Then, with the rotation of the grasping rod 22, the insertion block 44 slides out of the slot 43 and slides along the end face of the driving wheel 31. When the grasping rod 22 drives the suction cup 231 to move to the glass slide 7, the insertion block 44 slides along the driving wheel 31 to the position of the next slot 43, and then is inserted into the slot 43 under the push of the driving spring 45. Then, when the hydraulic cylinder 21 drives the grasping rod 22 to contract, the grasping rod 22 drives the driving rod 42 to rotate away from the grasping hole 182. The driving rod 42 drives the driving wheel 31 to rotate through the cooperation of the insertion block 44 and the slot 43. The driving wheel 31 drives the conveyor belt 33 to rotate, and the conveyor belt 33 moves the placement box 35 downward. When the grasping rod 22 rotates to the limit position, the glass slide 7 is located above the placement box 35. Then, the grasping rod 22 presses the microswitch 26, and the microswitch 26 controls the vacuum generator 233 to cut off the power. At this time, the glass slide 7 falls into the placement box 35, thereby realizing the grasping and transportation of the glass slide 7.

[0055] Refer to Figure 10 、 Figure 11 and Figure 12 , the placement box 35 is composed of a box body 351, a baffle 352, and slide rails 353. There is a discharge port 354 below the box body 351. The number of slide rails 353 is two, and both of the two slide rails 353 are located at the bottom of the box body 351. The discharge port 354 is located between the two slide rails 353. One end of each slide rail 353 bends towards the box body 351 and is fixedly connected to the box body 351. The baffle 352 is slidably arranged on the two slide rails 353. A support spring 355 is fixedly provided at the bent portion of each slide rail 353, and the other end of the support spring 355 is fixedly arranged with the baffle 352. A material placing block 356 is provided on the baffle 352. A material placing plate 5 is provided on the transport cylinder 18. The material placing plate 5 is arranged in the vertical direction. A guiding surface 51 is provided at the top end of the material placing plate 5. The guiding surface 51 slopes from the side of the material placing plate 5 away from the conveyor belt 33 towards the side close to the material placing plate 5. The material placing block 356 slides onto the material placing plate 5 along the guiding surface 51, causing the discharge port 354 to open. An elastic buffer pad is provided in the collection box 6. The elastic buffer pad can be a down pad. Each time the slide glass 7 falls into the collection box 6, the inside of the collection box 6 is cleaned once.

[0056] When transporting the slide glass 7, as the slide glass 7 falls into the placement box 35, then the grasping rod 22 makes the next grasp. With the continuous reciprocating rotation of the grasping rod 22, the placement box 35 moves downward along with the conveyor belt 33. When the placement box 35 moves to the position of the material placing plate 5, the material placing block 356 slides along the guiding surface 51. At this time, the material placing block 356 pulls the baffle 352 to slide towards the material placing plate 5, and the discharge port 354 begins to open. When the material placing block 356 completely slides onto the material placing plate 5, the discharge port 354 is opened, and the support spring 355 extends. The slide glass 7 falls into the collection box 6, and then the slide glass 7 is cleaned, thereby realizing the removal and collection of the slide glass 7, improving the convenience of removing the slide glass 7. Then, as the placement box 35 slides, the material placing block 356 disengages from the material placing plate 5, and the baffle 352 blocks the discharge port 354 under the pull of the support spring 355.

[0057] The implementation principle of a double-sided planar polishing machine with automatic blanking in an embodiment of this application is as follows: When removing the glass slide 7, first rotate the driving motor 15 and the rotating motor 114. The rotating motor 114 drives the transport cylinder 18 and the planetary gear 14 to rotate synchronously. When the laser sensor 19 detects that the glass slide 7 rotates to the grasping hole 182, the laser sensor 19 controls the rotating motor 114 and the driving motor 15 to cut off the power. Then, the hydraulic cylinder 21 extends, and the hydraulic cylinder 21 pushes the grasping rod 22 to extend out of the grasping hole 182. At this time, the grasping rod 22 drives the driving rod 42 to rotate through the connecting rod 41, and the driving rod 42 drives the insertion block 44 to slide along the driving wheel 31. When the grasping rod 22 drives the suction cup 231 to rotate onto the glass slide 7, the suction cup 231 adsorbs the glass slide 7. At this time, the insertion block 44 slides to the position of the next slot 43, and the insertion block 44 is inserted into the slot 43 under the push of the driving spring 45. When the hydraulic cylinder 21 pulls the grasping rod 22 to contract into the transport cylinder 18, the grasping rod 22 drives the driving rod 42 to rotate in the reverse direction through the connecting rod 41, and the driving rod 42 drives the driving wheel 31 to rotate through the insertion block 44. The driving wheel 31 drives the placement box 35 to move downward through the conveyor belt 33. When the suction cup 231 drives the glass slide 7 to rotate to the position of the conveyor belt 33, the placement box 35 moves to the lower side of the glass slide 7. At this time, the grasping rod 22 presses the microswitch 26, and the microswitch 26 controls the vacuum generator 233 to cut off the power, and the glass slide 7 detaches from the suction cup 231 and falls into the placement box 35. Then, as the grasping rod 22 continuously grasps the glass slide 7, the driving wheel 31 continuously drives the glass slide 7 to move downward through the conveyor belt 33. When the placement box 35 moves downward to the discharging plate 5, the discharging block 356 slides onto the discharging plate 5 along the guiding surface 51. At this time, the discharging block 356 drives the baffle 352 to slide to open the discharging port, and the glass slide 7 falls from the placement box 35 into the collection box 6, thereby realizing the removal and transportation of the glass slide 7 and improving the convenience of blanking the glass slide 7.

[0058] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
