In the specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0036] The utility model provides a kind of feeding and discharging platform device in some embodiments, for conveying workpiece. Wherein, workpiece can be various plate-shaped materials, for example, glass sheet. In the following, workpiece is taken as glass sheet for example to be explained. Feeding and discharging platform device can be docked with coating equipment, edge grinding equipment, cutting equipment etc., so that glass sheet is corrected in position before entering next equipment processing.

[0037] Please refer to Figure 1 And Figure 2 In some embodiments, feeding and discharging platform device 100 includes conveying mechanism 10, jacking mechanism 20 and correction mechanism 30, conveying mechanism 10 is used to support and convey glass sheet in preset direction, jacking mechanism 20 is elevated to the height required for correction when glass sheet reaches correction position, and correction mechanism 30 is clamped and corrected to the glass sheet elevated to the correction height by jacking mechanism 20.

[0038] In actual operation, glass sheet is first placed on conveying mechanism 10, and then conveyed by conveying mechanism 10 in preset direction, such as Figure 1 Conveying mode is from back to front. When glass sheet is conveyed to preset correction position, jacking mechanism 20 starts to work. Jacking mechanism 20 elevates glass sheet to correction height, at this time, glass sheet is completely separated from conveying mechanism 10 and suspended above conveying mechanism 10. After glass sheet reaches correction height, correction mechanism 30 starts to work, and correction mechanism 30 corrects the position of glass sheet by clamping at least two opposite sides of glass sheet. During clamping and correction, relative displacement occurs between glass sheet and support block 231 of jacking mechanism 20. Since the contact part of jacking mechanism 20 with glass sheet is provided with resistance reduction structure 21, the friction force on the surface of glass sheet can be reduced, so that the correction process is more smooth, and the risk of leaving scratches on the surface of glass sheet during correction process can be reduced.

[0039] After correction, jacking mechanism 20 is started again, and glass sheet is lowered with jacking mechanism 20 under the action of its own gravity, so that glass sheet falls back to conveying mechanism 10. Then, conveying mechanism 10 will continue to convey glass sheet to the next process or position, to prepare for the next round of operation.

[0040] wherein the correction position is a fixed value preset according to the position of the lifting mechanism, and the glass sheet should be above the lifting mechanism when the glass sheet is at the correction position. In actual use, whether the glass sheet reaches the correction position can be judged by distance sensing, photographing recognition and the like; the correction position can also be the initial position where the glass sheet is placed on the conveying mechanism 10 by an external device. The correction height is a fixed value preset according to the correction mechanism 30, and the correction mechanism 30 can contact the edge of the glass sheet when the glass sheet is at the correction height.

[0041] The following will specifically describe the components in the feeding and discharging platform device 100.

[0042] Please refer to Figure 1 and Figure 2 , the conveying mechanism 10 can include a rack 11, a second driving member 12 and a plurality of conveying shafts 13. The rack 11 is a support frame of the entire feeding and discharging platform device 100, which provides a stable mounting basis for each mechanism and also provides necessary strength and rigidity. The second driving member 12 is the power source of the conveying mechanism 10, which provides necessary driving force to drive the conveying shafts 13 to rotate. The number of the conveying shafts 13 is plural, and the plurality of conveying shafts 13 are arranged side by side on the rack 11. Specifically, the axis of the conveying shaft 13 is along the left-right direction, and the plurality of conveying shafts 13 are arranged at intervals in the front-rear direction on the rack. The plurality of conveying shafts 13 are simultaneously driven by the second driving member 12 to rotate at a constant speed in the same direction, thereby conveying the glass sheet placed on the conveying shaft 13.

[0043] When the glass sheet is placed on the conveying mechanism 10, at least two conveying shafts 13 will simultaneously support it. This design ensures the basic stability of the glass sheet during conveying and avoids the risk of vibration and sliding caused by single-point support. Of course, the glass sheet can also be simultaneously supported by 3, 4 or even more conveying shafts 13, which is not limited in the present application.

[0044] During the conveying of the glass sheet, the glass sheet will pass through different conveying shafts 13 in turn as the conveying shafts 13 rotate and move. In order to ensure the continuity of transportation, a design of at least three conveying shafts 13 simultaneously supporting the glass sheet at a certain moment can be adopted. That is, during the movement of the glass sheet from one conveying shaft 13 to the next conveying shaft 13, there will always be at least one additional conveying shaft 13 supporting it, ensuring smooth transition of the glass sheet during the movement from one conveying shaft 13 to the next conveying shaft 13, thereby improving the stability and continuity of the glass sheet during the entire conveying process.

[0045] The rack 11 is provided with two opposite support seats 111, and the two ends of the conveying shaft 13 are rotationally connected with the two support seats 111 respectively. In some embodiments, the support seat 111 is provided with a plurality of mounting positions, and a bearing is arranged in each mounting position, and the end of the conveying shaft 13 penetrates through the bearing and is rotationally connected with the support seat 111 through the bearing. In other embodiments, the support seat 111 can also be provided in a split manner, that is, two support seats 111 are provided corresponding to each conveying shaft 13, and each support seat 111 is provided with one mounting position, and the present embodiment does not limit this.

[0046] Each conveying shaft 13 needs to be drivingly connected with the second driving member 12. Specifically, the second driving member 12 can be a motor, and each conveying shaft 13 can be directly driven by the output shaft of the second driving member 12, or can be drivingly connected with the adjacent conveying shaft 13. The transmission mode can adopt chain transmission, belt transmission or gear transmission, and the present embodiment does not limit this.

[0047] In some embodiments, the transmission mode adopts belt transmission. Specifically, the same side end of each conveying shaft 13 is continuously provided with two synchronous wheels in the axial direction, as shown in Figure 1 The conveying direction of the glass sheet is from the rear to the front. In order to better understand the transmission relationship between the conveying shafts 13, the plurality of conveying shafts 13 can be divided into front end conveying shafts 13, rear end conveying shafts 13 and a plurality of intermediate conveying shafts 13 between the front end conveying shafts 13 and the rear end conveying shafts 13. For the two synchronous wheels at the end of any intermediate conveying shaft 13, one of the synchronous wheels is connected with the synchronous wheel on the conveying shaft 13 located on the front side thereof, and the other synchronous wheel is connected with the synchronous wheel on the conveying shaft 13 located on the rear side thereof. As for the front end conveying shaft 13 or the rear end conveying shaft 13, at least one of them is drivingly connected with the output shaft of the second driving member 12 through the synchronous belt. When the second driving member 12 is started, the conveying shaft 13 connected with the synchronous belt can be driven to start rotating, and then the synchronous belt transmission relationship between the conveying shafts 13 is achieved, so that all the conveying shafts 13 are synchronously driven.

[0048] The conveying shaft 13 comprises a shaft body 131 and a plurality of buffer rings 132. The end of the shaft body 131 penetrates through the corresponding bearing and is rotationally connected with the support seat 111 through the bearing. The synchronous wheels are also mounted on the part of the shaft body 131 extending out of the mounting seat. The plurality of buffer rings 132 are sleeved on the part of the shaft body 131 between the two support seats 111 and are arranged in sequence along the axial direction of the shaft body 131. The buffer ring 132 can be a rubber ring, a silica gel ring or the like, which plays a buffering role in the process of conveying the glass sheet, so as to avoid damage to the glass sheet due to vibration and bumping during conveying.

[0049] In an example, the buffer rings 132 on any two adjacent conveying shafts 13 are arranged staggeredly, which can avoid the force of the buffer rings 132 on the glass sheet during the conveying process always being biased to one side, thereby avoiding the problem of the glass sheet being continuously deviated during the conveying process.

[0050] Please refer to Figure 2 and Figure 3 The jacking mechanism 20 comprises a first driving member 22 and a push plate 23, the first driving member 22 provides the driving force required for jacking, one end of the first driving member 22 can be directly connected with the rack 11 or connected with a bottom plate 24 fixed to the rack 11, and the other end of the first driving member 22 is connected with the push plate 23. The top surface of the push plate 23 is provided with a plurality of support blocks 231, and the top surface of each support block 231 is provided with a resistance reduction structure 21, and the first driving member 22 drives the push plate 23 to move in the height direction. By arranging the resistance reduction structure 21 on the support block 231 protruding from the top surface of the push plate 23, a scattered dot-shaped support is formed on the glass sheet, which can reduce the contact surface with the glass sheet during jacking, thereby effectively reducing the frictional resistance.

[0051] The first driving member 22 can be selected from a gas cylinder, a linear motor, a screw nut assembly driven by a motor, a gear and rack assembly, a cam assembly, etc., and the present embodiment is not limited thereto.

[0052] The push plate 23 can be a long strip-shaped plate extending in the left-right direction, and the support blocks 231 on the push plate 23 are arranged at intervals in the left-right direction. Of course, the support blocks 231 can also be arranged in other forms, and the present embodiment is not limited thereto. In order to ensure the stability of the glass sheet in the jacked state, two, three or even more jacking mechanisms 20 can be provided, and the jacking mechanisms 20 can be extended from the gap between adjacent two conveying shafts 13. During the conveying process of the conveying mechanism 10, the push plate 23 and the support blocks 231 and the resistance reduction structures 21 on the push plate 23 are kept below the top edge of the conveying shaft 13. When it is necessary to jack up the glass sheet, the first driving member 22 drives the push plate 23 and the support blocks 231 and the resistance reduction structures 21 on the push plate 23 to rise from the gap between the conveying shafts 13 and jack up the glass sheet.

[0053] The support block 231 is at least partially made of a buffer material, which generally has a lower hardness and a higher elasticity. When in contact with the glass sheet, the buffer material can absorb part of the impact force, avoiding rigid collision with the glass sheet, thereby reducing damage to the glass sheet.

[0054] Common buffer materials include rubber, silicone, polyurethane foam, air cushion, etc. They can deform under pressure, thereby playing a buffering role.

[0055] For example, the top of the support block 231 can be made of rubber, or the entire support block 231 can be made of rubber, and the present embodiment is not limited thereto.

[0056] The resistance-reducing structure 21 can be implemented by using lubricating materials, rolling elements (such as balls or rollers), or other friction-reducing techniques. In practical applications, the resistance-reducing structure 21 can include a resistance-reducing layer, such as flannel, polytetrafluoroethylene (PTFE) film, nylon cloth, or the like, arranged on the top surface of the support block 231. The resistance-reducing layer can be fixed on the top surface of the support block by adhesion or the like.

[0057] Please refer to Figure 2 and Figure 3 When the first driving member 22 is connected to the bottom plate 24, the bottom plate 24 and the push plate 23 are both arranged in the horizontal direction, and the push plate 23 is located on the upper side of the bottom plate 24. The two ends of the bottom plate 24 are fixed to the rack 11, forming a stable support structure and facilitating the maintenance of the same reference with the conveying shaft 13 in the conveying mechanism 10. The first driving member 22 can be a pneumatic cylinder, which is installed between the push plates 23 of the bottom plate 24. The extension and retraction of the pneumatic cylinder directly drives the push plate 23 to rise or fall.

[0058] In order to improve the stability of the push plate 23 during movement, a guide rod structure can be used for guidance. Specifically, the bottom of the push plate 23 is connected with a guide rod 25, and the bottom plate 24 is connected with a linear guide 26, which has a sliding channel or groove matched with the guide rod 25. The guide rod 25 can be slidingly connected in the height direction in the sliding channel or groove. Thus, the shaking of the push plate 23 during lifting is limited, and the push plate 23 maintains a more stable motion trajectory.

[0059] The number of guide rods 25 can be two, each equipped with a linear guide 26, and the guide rod 25 and the corresponding guide are slidingly connected in the height direction. The two guide rods 25 are distributed on both sides of the first driving member 22, forming a stable support structure. This design can significantly reduce the shaking and tilting of the push plate 23 during lifting, thereby improving the stability of the entire jacking mechanism 20. The two guide rods 25 and the corresponding linear guides 26 can also jointly bear lateral forces, preventing the lateral forces from acting directly on the first driving member 22. This reduces the risk of damage to the first driving member 22 caused by lateral forces, improving the reliability and durability of the first driving member 22.

[0060] Please refer to Figure 1 , Figure 2 and Figure 3The correction mechanism 30 comprises a fixed plate 31, a driving assembly 32 and two clamping members 33 arranged oppositely. The fixed plate 31 can be connected with the rack 11 as the base of the correction mechanism 30 to provide a stable support and mounting platform for other components of the correction mechanism 30. The driving assembly 32 is the power source of the correction mechanism 30 for driving the two clamping members 33 to move close to or away from each other to realize the clamping or releasing of the glass sheet. The clamping members 33 are connected with the fixed plate 31 through sliding connection to realize the movement in the left-right direction. When the glass sheet is lifted to the correction height by the lifting mechanism 20, the driving assembly 32 of the correction mechanism 30 is started to drive the two clamping members 33 to move close to each other. The clamping members 33 clamp the glass sheet accurately. During the clamping process, the clamping members 33 can exert a certain pressure or torque on the glass sheet to correct the position or shape of the glass sheet.

[0061] After the correction is completed, the driving assembly 32 drives the two clamping members 33 to move away from each other to release the glass sheet. The lifting mechanism 20 and the conveying mechanism 10 can continue to perform other operations, such as lowering the glass sheet to the conveying mechanism 10 and conveying the glass sheet to the next process.

[0062] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , in order to better show the specific structure of the correction mechanism 30, Figure 4 and Figure 1 are not exactly the same. The driving assembly 32 comprises a third driving member 321, a rotating disc 322 and two connecting rods 323. The third driving member 321 can be a motor. The third driving member 321 is connected with the fixed plate 31. The output end of the third driving member 321 is connected with the rotating disc 322. The third driving member 321 provides power for the entire driving assembly 32. The rotating disc 322 is located on the upper side of the fixed plate 31. The two connecting rods 323 are centrally symmetrically distributed along the rotation axis of the rotating disc 322. The two connecting rods 323 and the two clamping members 33 are arranged one-to-one. One end of the connecting rod 323 is rotationally connected with the corresponding clamping member 33. The other end is rotationally connected with the rotating disc 322 to form a stable transmission path. The third driving member 321 drives the rotating disc 322 to rotate. The rotation of the rotating disc 322 drives the connecting rod 323 to swing and thus drives the clamping member 33 to slide in the left-right direction.

[0063] Since the connecting rods 323 are centrally symmetrically distributed along the rotation axis of the rotating disc 322 and the two connecting rods 323 and the two clamping members 33 are arranged one-to-one, the synchronism and balance of the clamping members 33 during the movement can be improved. Therefore, the above structure can realize the accurate clamping and positioning of the glass sheet.

[0064] Please refer to Figure 4 , Figure 8 and Figure 9Specifically, the rotating disc 322 comprises a disc body 3221 and a connecting base 3222, the outer diameter of the disc body 3221 is larger than that of the connecting base 3222, that is, the disc body 3221 has an outer edge partially exposed to the connecting base 3222 in the radial direction. The exposed part is provided with a mounting hole 3224, and the connecting rod 323 is rotationally connected with the mounting hole 3224 through a rotating shaft or the like. The greater the distance between the mounting hole 3224 and the axis of the disc body 3221, the greater the displacement that can be achieved by the disc body 3221 rotating through the same angle. In the embodiment, the mounting hole 3224 is arranged close to the outer edge of the disc body 3221, thereby expanding the movable range of the clamping plate 331.

[0065] Specifically, the connecting base 3222 is located at the bottom of the disc body 3221, and the connecting base 3222 comprises a connecting portion 3225 and two oppositely arranged clamping arms 3226. The connecting portion 3225 is connected with the bottom of the disc body 3221, and there is a gap between the top surface of the clamping arm 3226 and the bottom surface of the disc body 3221. The two clamping arms 3226 are connected to the same side of the connecting portion 3225, and the two clamping arms 3226 together with the connecting portion 3225 enclose a mounting space 3227, and a gap is formed between the end portions of the two clamping arms 3226. A through hole is formed in one of the clamping arms 3226, and a threaded hole is formed in the other clamping arm 3226. An adjusting bolt can be connected through the through hole and the threaded hole, and the two clamping arms 3226 can be clamped around the output shaft of the third driving member 321 by screwing the adjusting bolt.

[0066] The output shaft of the third driving member 321 and the rotating disc 322 can be connected through a key to achieve torque transmission, and a key groove 3228 penetrates the disc body 3221 and the connecting base 3222. Specifically, the key groove 3228 is located on the connecting portion 3225 and communicates with the mounting space 3227.

[0067] In other embodiments, the rotating disc 322 can be rotationally connected with the fixed plate through a bearing, and only torque transmission is required between the rotating disc 322 and the third driving member 321, without the need to set a complex connecting mechanism. Thus, the structure of the rotating disc 322 can be simplified.

[0068] Please refer to Figure 1 , Figure 2 and Figure 4The clamping piece 33 comprises a clamping plate 331 and a plurality of support columns 332. The clamping plate 331 is in sliding connection with the fixed plate 31, and the clamping plate 331 and the fixed plate 31 are located below the conveying shaft 13. The plurality of support columns 332 of the same clamping piece 33 are arranged in the front-rear direction on the clamping plate 331. Each of the two clamping pieces 33 has a row of support columns 332, and the two rows of support columns 332 are arranged in one-to-one correspondence in the left-right direction and pass through the gap between the adjacent conveying shafts 13. When the third driving piece 321 is not started, the support columns 332 are distributed in two rows as a whole, and the two rows of support columns 332 are arranged close to the left and right side edges of the rack 11, so as to leave a sufficient gap between the two rows of support columns 332 for the glass sheet to pass through. When the third driving piece 321 is started, it can drive the two clamping plates 331 to move towards each other, that is, the two rows of support columns 332 move in the direction close to the left and right edges of the glass sheet, so as to abut against and push the glass sheet to correct the position of the glass sheet.

[0069] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 , the clamping plate 331 can be in sliding connection with the fixed plate 31 through a guide rail and sliding block structure, so as to guide the movement direction of the clamping plate 331. Each clamping plate 331 can correspond to two guide rail and sliding block structures, which are arranged in parallel, so as to reduce the shaking of the clamping plate 331 during movement and avoid the deflection or jamming phenomenon caused by uneven force.

[0070] The clamping plate 331 comprises a first plate body 3311 and a second plate body 3312 arranged in a T shape. The bottom plate 24 of the first plate body 3311 is in sliding connection with the fixed plate 31 through a guide rail and sliding block structure. The first plate body 3311 has a certain width in the front-rear direction, so as to leave sufficient installation space 3227 for the sliding block 342, and the guide rail 341 is installed on the fixed plate 31. The second plate body 3312 extends in the front-rear direction, and the support column 332 is fixed on the second plate body 3312.

[0071] During the correction process, the third driving piece 321 needs to rotate by a certain angle. Please refer to Figure 4 to Figure 7 , an induction sheet 351 can be arranged on the clamping plate 331, and an inductor 352 is arranged on the fixed plate 31. The inductor 352 and the induction sheet 351 can cooperate to correct the third driving piece 321. In order to avoid interference with other structures, the induction sheet 351 can be installed on one side edge of the fixed plate 31. A limiting block 36 can be arranged on the fixed plate 31 to cooperate with the sliding block 342 or the protruding structure on the clamping plate 331 to limit the stroke of the clamping plate 331. In the case of motor setting or induction sheet 351 failure, the limiting block 36 can block the sliding block 342 or the protruding structure to prevent the clamping plate 331 from having too large a stroke and clamping or separating from the glass sheet.

[0072] In other embodiments, the inductor 352 can be installed on the clamping plate 331, and the inductive sheet 351 can be installed on the fixed plate 31, which are not limited in this embodiment.

[0073] The support column 332 includes a column body 3321 and a roller 3322. The column body 3321 is arranged on the clamping plate 331 and extends in the height direction to protrude from the gap between the conveying shafts 13. The roller 3322 is arranged at the top end of the column body 3321. The roller 3322 can be rotatably connected to the column body 3321, allowing the roller 3322 to freely roll when contacting the edge of the glass sheet, thereby reducing the frictional resistance, helping to reduce the wear of the glass sheet, and improving the correction efficiency. The outer side wall of the roller 3322 can be provided with a buffer layer, which is usually made of soft and wear-resistant materials such as rubber, polyurethane, etc. When the roller 3322 contacts the edge of the glass sheet, the buffer layer can absorb part of the impact force, playing a buffering role, thereby avoiding damage to the glass sheet due to direct impact on the roller 3322.

[0074] The outer diameter of the roller 3322 can be greater than the outer diameter of the column body 3321, or the roller 3322 can be rotatably sleeved on the end of the column body 3321, which is not limited in this application.

[0075] Please refer to Figure 1 , Figure 4 and Figure 6 The two ends of the fixed plate 31 can be connected to the rack 11 through the cushion block 37. The cushion block 37 can raise the height of the fixed plate 31 and the structure installed on the fixed plate 31, thereby controlling the length of the support column 332, avoiding the phenomenon that the length of the support column 332 is too long to cause a large moment during clamping and correcting, which is beneficial to maintaining the shape of the support column 332, that is, maintaining the accuracy of the support frame for correcting the glass sheet.

[0076] In other embodiments, the two clamping pieces 33 can also be driven by different third driving pieces 321, respectively. The two clamping pieces 33 are located at the edges of the rack 11 in the left-right direction and above the conveying shafts 13. Since the clamping piece 33 does not interfere with the conveying shaft 13 when moving in the left-right direction, the clamping piece 33 can adopt a plate-shaped structure, and the correction is realized by the continuous surface contacting the edge of the glass sheet. This embodiment is not limited in this regard.

[0077] In other embodiments, the correction mechanism 30 can also drive the four clamping pieces 33 to be centered by the driving assembly 32, and the four corners of the glass sheet are clamped and positioned to correct the glass sheet; the two pairs of clamping pieces 33 can also be driven by the driving assembly 32 to be centered, and one pair of clamping pieces 33 can be in contact with the two edges of the glass sheet in the front-back direction, and the other pair of clamping pieces 33 can be in contact with the two edges of the glass sheet in the left-right direction to achieve clamping correction. This embodiment is not limited.
