Description

Technical Field

[0001] The present invention relates to the technical field of turning equipment, in particular to a plate-shaped object turning machine and a plate turning method. Background Art

[0002] In many technical fields, after the upper surface of a plate-like object is processed, it needs to be flipped 180° so that the lower surface of the plate faces upward to facilitate processing of the lower surface. In many technical fields, the 180° flipping of plates is still done manually; with the continuous development of science and technology, some automatic flipping equipment has emerged, but this type of equipment often uses a robot to clamp the plate, and then flip the plate through the robot. The structure of this type of equipment is generally very complex and the cost is very high. There are also some devices that weld four flip plates arranged in a cross on the rotating shaft, place the plate on the flip plate, and rotate the rotating shaft to drive the flip plate and the plate on the flip plate to achieve a 180° flip; the area required for the flipping station of this type of equipment is large, resulting in a complex structure and a large equipment size; and when flipping the plate, a height difference will be generated, which is easy to damage some fragile plates. Summary of the invention

[0003] The purpose of the present invention is to propose a plate-like object turning machine and a method for turning a plate, aiming to solve the technical problems in the prior art that the turning device has a relatively complex structure, bulky equipment and high manufacturing cost.

[0004] To achieve the above object, the present invention provides a plate-like object turning machine, comprising:

[0005] A frame, on which a turning station is provided;

[0006] A conveying mechanism, including a loading conveying mechanism and a unloading conveying mechanism, wherein the loading conveying mechanism and the unloading conveying mechanism are both installed on the frame and are respectively located on both sides of the flipping station;

[0007] The turning mechanism comprises a vertical slide rail and a slide plate. The vertical slide rail is mounted on the frame and is perpendicular to the conveying mechanism. The vertical slide rail is located directly below the turning station. The slide plate is slidably mounted on the vertical slide rail. The turning machine has a simple structure, a small volume, a low cost, a high turning efficiency, and can prevent fragile panels from being damaged during the turning process. It is particularly suitable for use on continuous production lines.

[0008] Preferably, the loading conveying mechanism comprises a first conveyor belt, a first roller, a first transverse slide rail and a first driving slide seat;

[0009] The first conveyor belt and the first transverse slide rail are both installed on the frame, and the first transverse slide rail is located between the first conveyor belt and the flipping station;

[0010] The first driving slide can be slidably mounted on the first transverse slide rail, and the first roller is mounted on the first driving slide. First, the first conveyor belt can smoothly transport the plate to the flipping station; second, the first driving slide can drive the first roller to move so as to move the center of gravity of the plate to the side close to the unloading conveying mechanism; third, the first transverse slide rail can provide a sliding track for the first driving slide and the first roller, so that the two can move smoothly and accurately between the first conveyor belt and the flipping station.

[0011] Preferably, the unloading conveying mechanism comprises a second conveyor belt, a second roller, a second transverse slide rail and a second driving slide seat, the second conveyor belt and the second transverse slide rail are both mounted on the frame, and the second transverse slide rail is located between the second conveyor belt and the flipping station, the second driving slide seat is slidably mounted on the second transverse slide rail, and the second roller is mounted on the second driving slide seat. Firstly, the design of the second conveyor belt can smoothly transport the flipped plate to the next station; secondly, the second driving slide seat can support the plate when the plate begins to deviate to one side of the unloading conveying mechanism, avoiding the need for the plate to directly rest on the second conveyor belt, thereby avoiding the large force of the plate hitting the second conveyor belt when flipping, which is easy to cause damage to fragile plates (such as tiles); thirdly, the second transverse slide rail can provide a sliding track for the second slide plate and the second roller, so that both can move smoothly and accurately between the second conveyor belt and the flipping station.

[0012] Preferably, it further comprises a drive control system, wherein the drive control system comprises a general controller, a first drive device, a second drive device and a third drive device;

[0013] The master controller is electrically connected to the first drive device, the second drive device and the third drive device;

[0014] The first driving device is used to drive the first driving slide to move, the second driving device is used to drive the second driving slide to move, and the third driving device is used to drive the sliding plate to move. Not only the automation of flipping the plate is realized, but also the whole flipping process is accurate and efficient through the control of the master controller.

[0015] Preferably, the first roller is covered with a first soft rubber layer, and the second roller is covered with a second soft rubber layer, which can greatly reduce the wear of the first roller and the second roller on the plate, and can also avoid scratching some plates such as tiles.

[0016] Preferably, the sliding plate is provided with a groove with an opening facing upwards. The design of the groove can provide a position for accommodating one end of the plate, and can ensure the stability of the plate during the flipping process of the plate to prevent the plate from falling.

[0017] Preferably, the groove is a V-shaped groove, and the opening angle α of the V-shaped groove is 90 to 120°.

[0018] Preferably, a third soft adhesive layer is attached to the side wall of the groove. The third soft adhesive layer can protect the edges and corners of the plate to prevent the plate from collapsing or bursting due to collision when it is pressed against the groove.

[0019] In another aspect, the present invention provides a method for flipping a plate, using the plate-shaped object flipping machine as described above, comprising the following steps:

[0020] Step 1: The first conveyor belt transports the plate to the flipping station and places one end of the plate on the sliding plate;

[0021] Step 2: The sliding plate receives the plate and moves downward, and at the same time, the first roller abuts against the plate and moves toward the side where the sliding plate is located, until the plate is tilted to the side where the second conveyor belt is located;

[0022] Step 3: The slide plate moves upward and causes the plate to fall onto the second conveyor belt to complete the flipping.

[0023] Preferably, in step 2, the plate is tilted toward the side where the second conveyor belt is located and abuts against the second roller;

[0024] In step 3, when the sliding plate moves upward on the vertical slide rail, the second roller moves toward the second conveyor belt. Not only does the above-mentioned turning machine have the beneficial effects, but the turning of the plate is simpler and faster.

[0025] The plate-like object turning machine and the method for turning a plate of the present invention have at least the following beneficial effects: the plate-like object turning machine transports the plate to the turning station through a loading conveying mechanism, and then the plate is offset to the unloading conveying mechanism through the downward movement of the sliding plate in the turning mechanism and the pushing of the loading conveying mechanism; then the plate is dropped flatly onto the unloading conveying mechanism through the rising of the sliding plate; the turning machine of the present technical solution has a simple structure, a small size, a low cost, and a high turning efficiency, and can also prevent fragile plates from being damaged during the turning process; it is particularly suitable for use on continuous production lines.

[0039] like Figures 1 to 6 As shown, the plate-shaped object turning machine comprises:

[0040] A frame 1, on which a turning station 11 is provided;

[0041] The conveying mechanism 2 includes a loading conveying mechanism 21 and a unloading conveying mechanism 22. The loading conveying mechanism 21 and the unloading conveying mechanism 22 are both installed on the frame 1 and are respectively located on both sides of the flipping station 11;

[0042] The flipping mechanism 3 includes a vertical slide rail 31 and a slide plate 32. The vertical slide rail 31 is installed on the frame 1 and is perpendicular to the conveying mechanism 2. The vertical slide rail 31 is located directly below the flipping station 11. The slide plate 32 is slidably installed on the vertical slide rail 31.

[0043] The frame 1 is used to install the conveying mechanism 2 and the flipping mechanism 3. A flipping station 11 is provided on the frame 1. The flipping station 11 is mainly used to provide an area for the flipping mechanism 3 to flip the plate 5; the conveying mechanism 2 includes a loading conveying mechanism 21 and a unloading conveying mechanism 22, both of which are installed on the frame 1; the loading conveying mechanism 21 is used to transport the plate 5 to the flipping station 11, and the unloading conveying mechanism 22 is used to unload the flipped plate 5 from the flipping station 11 to the next station; therefore, the loading conveying mechanism 21 and the unloading conveying mechanism 22 are respectively located on both sides of the flipping station 11. The flipping mechanism 3 includes a vertical slide rail 31 installed on the frame 1 and a slide plate 32 installed on the vertical slide rail 31. The vertical slide rail 31 is perpendicular to the conveying mechanism 2 (that is, if the conveying mechanism 2 is horizontally installed on the working surface of the frame 1, the vertical slide rail 31 is installed perpendicular to the working surface of the frame 1); the flipping mechanism 3 is used to flip the plate 5, so the flipping mechanism 3 is arranged on the flipping station 11; specifically, the vertical slide rail 31 is installed directly below the flipping station 11, and the slide plate 32 can be installed on the vertical slide rail 31 so as to slide up and down. The loading conveyor mechanism 21 transports the plate 5 to the flipping station 11, and makes one end of the plate 5 rest on the sliding plate 32, and then the sliding plate 32 descends, and at the same time, the loading conveyor mechanism 21 continues to push the plate 5 to the side of the unloading conveyor mechanism 22; when the sliding plate 32 descends to a certain distance, and the loading conveyor mechanism 21 pushes the plate 5 to the side of the unloading mechanism for a certain distance, the plate 5 can be in a vertical state; because the plate 5 has a certain initial speed under the push of the loading mechanism, the loading mechanism does not The plate 5 is pushed again, but the plate 5 will still deviate to the side of the unloading conveying mechanism 22 (that is, the center of gravity of the plate 5 changes from between the slide plate 32 and the loading conveying mechanism 21 to between the slide plate 32 and the unloading conveying mechanism 22); when the plate 5 deviates to the side of the unloading conveying mechanism 22, the plate 5 rests on the unloading conveying structure; then the slide plate 32 moves upward, so that the plate 5 falls on the unloading conveying mechanism 22; finally, the unloading conveying mechanism 22 transports the plate 5 to the next workstation; at this point, the turning mechanism completes the 180° turning of the plate 5.

[0044] In many technical fields, the 180° flipping of plates is still done manually; with the continuous development of science and technology, some automatic flipping equipment has emerged, but this type of equipment often flips the plate 5 180° by using a robot to clamp the plate, and then flips the plate through the robot. The structure of this type of equipment is generally very complex and the cost is very high. There are also some devices that weld four flip plates arranged in a cross on the shaft, place the plate on the flip plate, and rotate the shaft to drive the flip plate and the plate on the flip plate to achieve a 180° flip; the area required for the flip station 11 of this type of equipment is large, resulting in a complex structure and a large equipment size; and when flipping the plate, a height difference will be generated, which is easy to damage some fragile plates. In the present technical solution, the plate 5 is transported to the turning station 11 by the loading conveying mechanism 21, and then the plate 5 is offset to the unloading conveying mechanism 22 by the downward movement of the slide plate 32 in the turning mechanism 3 and the push of the loading conveying mechanism 21; then the plate 5 is dropped flatly onto the unloading conveying mechanism 22 by the rise of the slide plate 32; the turning machine of the present technical solution has a simple structure, a small size, a low cost, and a high turning efficiency, and can also prevent the fragile plate 5 from being damaged during the turning process; it is particularly suitable for use on continuous production lines.

[0045] Furthermore, the loading conveying mechanism 21 includes a first conveying belt 211, a first roller 212, a first transverse slide rail 213 and a first driving slide seat 214;

[0046] The first conveyor belt 211 and the first transverse slide rail 213 are both installed on the frame 1, and the first transverse slide rail 213 is located between the first conveyor belt 211 and the flipping station 11;

[0047] The first driving slide 214 is slidably mounted on the first transverse slide rail 213 , and the first roller 212 is mounted on the first driving slide 214 .

[0048] The first conveyor belt 211 is installed on the frame 1, and the unturned plate 5 is transported from the first conveyor belt 211 to the turning station 11; the first transverse slide rail 213 is installed on the frame 1 and is located between the discharge end of the first conveyor belt 211 and the turning mechanism 3; the first driving slide 214 is installed on the first transverse slide rail 213, and the first driving slide 214 is installed with a first roller 212. The first driving slide 214 can slide on the first transverse slide rail 213 to drive the first roller 212 to move back and forth between the first conveyor belt 211 and the turning station 11. Generally, the height of the top of the first roller 212 is equal to or lower than the height of the top of the first conveyor belt 211. When the plate 5 is transported from the first conveyor belt 211 to the turning station 11 and one end thereof abuts against the slide plate 32, the slide plate 32 descends, and the first driving slider moves toward the slide plate 32 to change the plate 5 from a horizontal state to a vertical state. First, the first conveyor belt 211 can smoothly transport the panel 5 to the flipping station 11; second, the first driving slide 214 can drive the first roller 212 to move so as to move the center of gravity of the panel 5 to the side close to the unloading conveying mechanism 22; third, the first transverse slide rail 213 can provide a sliding track for the first driving slide 214 and the first roller 212, so that the two can move smoothly and accurately between the first conveyor belt 211 and the flipping station 11.

[0049] Furthermore, both ends of the first roller 212 are rotatably mounted on the first driving slide 214 around its central axis via a first bearing seat 215, and the top end of the first roller 212 is at the same horizontal height as the top end of the first conveyor belt 211, or the top end of the first roller 212 is lower than the top end of the first conveyor belt 211.

[0050] The first roller 212 is installed on the first driving slide 214 through the first bearing seat 215, and the first roller 212 can rotate around its central axis; the top of the first roller 212 is at the same horizontal height as the top of the first conveyor belt 211; such an arrangement can enable the first roller 212 to support the plate 5 when the plate 5 moves from the first conveyor belt 211 to the flipping station 11, so that the movement of the plate 5 is smoother; and the first roller 212 can rotate around its central axis during the movement of the plate 5, thereby avoiding the first roller 212 from bringing resistance to the movement of the plate 5 and avoiding the first roller 212 from causing wear on the plate 5.

[0051] Furthermore, the first roller 212 is provided with a first soft rubber layer 2121. The first soft rubber layer 2121 is made of a material with a certain elasticity, such as plastic. The first roller 212 is provided with the first soft rubber layer 2121, that is, the first soft rubber layer 2121 is attached to the outer wall of the first roller 212; such a configuration can greatly reduce the wear of the first roller 212 on the plate 5, and for some plates 5 such as tiles, scratches on the plate 5 can also be avoided.

[0052] Furthermore, the unloading conveying mechanism 22 includes a second conveyor belt 221, a second roller 222, a second transverse slide rail 223 and a second driving slide 224, the second conveyor belt 221 and the second transverse slide rail 223 are both installed on the frame 1, and the second transverse slide rail 223 is located between the second conveyor belt 221 and the flipping station 11, the second driving slide 224 is slidably installed on the second transverse slide rail 223, and the second roller 222 is installed on the second driving slide 224.

[0053] The second conveyor belt 221 is installed on the frame 1, and the turned workpiece is transported from the second conveyor belt 221 to the next station; the second transverse slide rail 223 is installed on the frame 1 and is located between the loading end of the second conveyor belt 221 and the turning machine; the second conveyor belt 221, the second transverse slide rail 223, the first transverse slide rail 213 and the first conveyor belt 211 are in the same straight line; a second driving slide 224 is installed on the second transverse slide rail 223, and a second roller 222 is installed on the second driving slide 224. The second driving slide 224 can slide on the second transverse slide rail 223 to drive the second roller 222 to move back and forth between the turning station 11 and the second conveyor belt 221. When the plate 5 tilts toward the side where the unloading conveyor mechanism 22 is located, the plate 5 rests on the second roller 222, and the second roller 222 is close to the flipping station 11; when the slide plate 32 moves upward, the second roller 222 simultaneously moves from the flipping station 11 to the second conveyor belt 221 to place the plate 5 horizontally on the second conveyor belt 221 and the second roller 222, and then the second conveyor belt 221 drives the plate 5 to move to the next station. First, the design of the second conveyor belt 221 can smoothly transport the flipped panel 5 to the next workstation; secondly, the second driving slide 224 can support the panel 5 when the panel 5 begins to deviate to the side of the unloading conveyor mechanism 22, thereby preventing the panel 5 from directly resting on the second conveyor belt 221, thereby preventing the panel 5 from hitting the second conveyor belt 221 with a large force when flipping, which can easily cause damage to fragile panels 5 (such as tiles); thirdly, the second transverse slide rail 223 can provide a sliding track for the second slide plate 32 and the second roller 222, so that the two can move smoothly and accurately between the second conveyor belt 221 and the flipping station 11.

[0054] Furthermore, both ends of the second roller 222 can be rotatably mounted on the second driving slide 224 around its central axis through a second bearing seat 225, and the top end of the second roller 222 and the top end of the second conveyor belt 221 can be in the same horizontal plane, or the top end of the second roller 222 is lower than the top end of the second conveyor belt 221.

[0055] The second roller 222 is installed on the second driving slide 224 through the second bearing seat 225, and the second roller 222 can rotate around its central axis; the top of the second roller 222 is at the same horizontal height as the top of the second conveyor belt 221; such an arrangement can enable the second roller 222 to support the plate 5 after the plate 5 is flipped over, so that the plate 5 can be more stable when it is completely moved onto the second conveyor belt 221; and the second roller 222 can rotate around its central axis when the slide plate 32 drives the plate 5 to rise, and when the plate 5 is completely moved onto the second conveyor belt 221, thereby avoiding the second roller 222 from bringing resistance to the movement of the plate 5 and avoiding the second roller 222 from causing wear on the plate 5.

[0056] Furthermore, the second roller 222 is provided with a second soft rubber layer 2221. The second soft rubber layer 2221 is made of a material with a certain elasticity, such as plastic. The second roller 222 is provided with a second soft rubber layer 2221, that is, the second soft rubber layer 2221 is attached to the outer wall of the second roller 222; such a configuration can greatly reduce the wear of the second roller 222 on the plate 5, and for some plates 5 such as tiles, scratches on the plate 5 can also be avoided.

[0057] Furthermore, it also includes a drive control system 4, which includes a general controller 41, a first drive device 42, a second drive device 43 and a third drive device 44;

[0058] The master controller 41 is electrically connected to the first driving device 42, the second driving device 43 and the third driving device 44;

[0059] The first driving device 42 is used to drive the first driving slide 214 to move, the second driving device 43 is used to drive the second driving slide 224 to move, and the third driving device 44 is used to drive the sliding plate 32 to move.

[0060] The first drive device 42, the second drive device 43 and the third drive device 44 are controlled by the main controller 41, and then the movement of the first drive slide 214, the second drive slide 224 and the slide plate 32 is controlled; such an arrangement not only realizes the automation of the flipping plate 5, but also makes the entire flipping process accurate and efficient through the control of the main controller 41.

[0061] Furthermore, the slide plate 32 is provided with a first start switch 321 at a side close to the loading conveying mechanism 21 , and the first start switch 321 is electrically connected to the main controller 41 .

[0062] The first start switch 321 can sense the position of the plate 5. When one end of the plate 5 moves onto the sliding plate 32, the first start switch 321 is triggered; the first start switch 321 feeds back the information to the main controller 41, and the main controller 41 controls the first drive device 42 to drive the first drive slide 214 to slide toward the side of the flipping station 11; at the same time, the main controller 41 controls the third drive device 44 to drive the sliding plate 32 to slide downward. The first start switch 321 is set to more accurately understand that the plate 5 has moved to the sliding plate 32, so that the entire control closed loop can operate more accurately. The first start switch 321 can be a gravity-pressed contact switch or a photoelectric switch, etc. Of course, the control closed loop of the entire flipping process can also use the method of measuring the stroke of the plate 5 to control the flipping of the plate 5. This method mainly depends on the design of the control logic and control method of the overall control system, which will not be repeated here.

[0063] Furthermore, a second starting switch 2241 is provided on the second driving slide 224 at a side close to the flipping station 11 , and the second starting switch 2241 is electrically connected to the main controller 41 .

[0064] The second start switch 2241 can sense the position of the plate 5. When the plate 5 deflects to one side of the unloading assembly (i.e., abuts against the second roller 222), the second start switch 2241 is triggered; the second start switch 2241 feeds back the information to the main controller 41; the main controller 41 controls the third drive device 44 to drive the slide plate 32 to move upward; at the same time, the main controller 41 controls the second drive device 43 to drive the second drive slide 224 to move toward the second conveyor belt 221. The second start switch 2241 is provided to more accurately understand that the plate 5 has abutted against the second roller 222, so that the entire control closed loop can operate more accurately. The second start switch 2241 can be a gravity-pressed contact switch or a photoelectric switch, etc.

[0065] Furthermore, the sliding plate 32 is provided with a groove 322 opening upward.

[0066] The design of the groove 322 can provide a position to accommodate one end of the plate 5. When one end of the plate 5 is against the sliding plate 32, one end of the plate 5 is located in the groove 322. Therefore, during the flipping process of the plate 5, the stability of the plate 5 can be ensured to prevent the plate 5 from falling.

[0067] Further, the groove 322 is provided with a pulley or a sliding roller on the side wall near the opening thereof. The pulley and the sliding roller can reduce the resistance of the plate 5 during the turning process and avoid scratching or damaging the plate 5.

[0068] Furthermore, the groove 322 is a V-shaped groove, and the opening angle α of the V-shaped groove is 90 to 120°. The groove 322 is a V-shaped groove, which can prevent the plate 5 from sliding too much in the groove 322, causing the plate 5 to be unstable and easy to fall. The opening angle α of the V-shaped groove is 90 to 120°. If the opening angle α is too small, it is inconvenient for the plate 5 to rest in the groove 322; if the opening angle α is too large, the stability of the plate 5 in the groove 322 is low; therefore, the opening angle α between 90 and 120° can achieve a better effect.

[0069] Furthermore, a third soft adhesive layer 323 is attached to the side wall of the groove 322 .

[0070] The third soft rubber layer 323 can be made of rubber, plastic, polyurethane and other materials. The third soft rubber layer 323 not only has a certain elasticity, but also has a certain wear resistance. Therefore, the third soft rubber layer 323 is attached to the side wall of the groove 322, which can protect the edges and corners of the plate 5 and prevent the plate 5 from collapsing or bursting due to collision when it is against the groove 322.

[0071] On the other hand, a method for flipping a plate, using the plate-shaped object flipping machine as described above, comprises the following steps:

[0072] Step 1: The first conveyor belt 211 transports the plate 5 to the flipping station 11, and places one end of the plate 5 on the sliding plate 32;

[0073] Step 2: The slide plate 32 receives the plate 5 and moves downward, while the first roller 212 presses against the plate 5 and moves toward the side where the slide plate 32 is located, until the plate 5 is tilted to the side where the second conveyor belt 221 is located;

[0074] Step 3, the slide plate 32 moves upward and causes the plate 5 to fall onto the second conveyor belt 221;

[0075] Repeat steps 1 to 3.

[0076] Furthermore, in step 2, the plate 5 is tilted toward the side where the second conveyor belt 221 is located and abuts against the second roller 222;

[0077] In step three, when the slide plate 32 moves upward on the vertical slide rail 31 , the second roller 222 moves toward the second conveyor belt 221 .

[0078] Please refer to Figure 6 , wherein the flipping process sequence follows the process sequence indicated by the arrows in the figure, and the specific method steps for flipping the plate 5 are as follows:

[0079] In step one, the unturned panel 5 is placed on the first conveyor belt 211, and the first conveyor belt 211 transports the unturned panel 5 to the flipping station 11. When one end of the panel 5 moves to the flipping station 11, the end of the panel 5 close to the flipping station 11 rests on the sliding plate 32 (specifically, rests on the groove 322 of the sliding plate 32) due to its own weight.

[0080] Step 2: The slide plate 32 receives one end of the workpiece, and then the slide plate 32 moves downward on the vertical slide rail 31 (specifically, the main controller 41 controls the third driving device 44 to drive the slide plate 32 to move downward); at the same time, the first roller 212 abuts against the plate 5 and moves toward the side where the slide plate 32 is located (specifically, the main controller 41 controls the first driving device 42 to drive the first driving slide 214 to slide on the first transverse slide rail 213 toward the side where the slide plate 32 is located, thereby driving the first roller 212 to slide toward the side where the slide plate 32 is located); The speed at which the slide plate 32 moves downward is equal to the speed at which the second roller 222 moves toward the side where the slide plate 32 is located; when the slide plate 32 descends to a certain position and the first roller 212 moves until the plate 5 is in a vertical state, the slide plate 32 and the first roller 212 stop moving. At this time, due to the action of the first roller 212, the plate 5 has a certain initial speed, so the plate 5 will tilt toward the side where the second conveyor belt 221 is located; at this time, the second roller 222 is close to the flipping station 11, so the plate 5 rests on the second roller 222;

[0081] Step three, the slide plate 32 moves upward on the vertical slide rail 31 (specifically, the main controller 41 controls the third drive device 44 to drive the slide plate 32 to move upward); at the same time, the second roller 222 moves on the second transverse slide rail 223 toward the side where the second conveyor belt 221 is located (specifically, the main controller 41 controls the second drive device 43 to drive the second drive slide 224 to move on the second transverse slide rail 223 toward the side where the second conveyor belt 221 is located); the speed at which the slide plate 32 moves upward is equal to the speed at which the second roller 222 moves toward the second conveyor belt 221; during the movement of the slide plate 32 and the second roller 222, the plate 5 slowly approaches the second conveyor belt 221; when the slide plate 32 rises to a certain position, the plate 5 after 180° flipping falls on the second conveyor; the operation of the second conveyor belt 221 transports the flipped plate 5 to the next workstation; at this point, the 180° flipping of the plate 5 is completed.

[0082] During the entire process of flipping the plate 5, the movement of the first roller 212, the slide 32 and the second roller 222 mainly depends on the specific position of the plate 5, and the specific position of the plate 5 can be obtained in many ways, such as travel switch, photoelectric switch, gravity pressure contact switch, etc.

[0083] The method for flipping a plate provided in the present solution uses the flipping machine as described above, which not only has the above-mentioned beneficial effects, but also makes the flipping of the plate 5 simpler and faster.

[0084] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
