[0021] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0022] The following is for reference. Figures 1 to 7 A sheet palletizing device according to an embodiment of the present invention will be described in detail.

[0023] refer to Figures 1 to 3 According to an embodiment of the present invention, a sheet palletizing device includes a frame 100, a palletizing module 200, a feeding module 300, and a jig-picking module 400. The frame 100 is provided with a picking position 110, a palletizing position 120, and a jig placement position 130. The palletizing module 200 is disposed on the frame 100 and includes a palletizing jig 210, a clamping mechanism 220, a guiding mechanism 230, and a driving mechanism 240. The clamping mechanism 220 clamps and fixes the palletizing jig 210, and the guiding mechanism 230 is disposed at the palletizing position 120 and is used to guide the posture of the sheet. The palletizing fixture 210 is used to receive the sheet material, and the driving mechanism 240 is used to drive the clamping mechanism 220 to move between the fixture placement position 130 and the palletizing position 120 so that the sheet material guided by the guiding mechanism 230 can be stacked on the palletizing fixture 210. The feeding module 300 is set on the frame 100 and is used to place the sheet material located at the picking position 110 on the guiding mechanism 230. The jig removal module 400 is set on the frame 100 and is used to pick up and place the palletizing fixture 210 located on the clamping mechanism 220 at the fixture placement position 130.

[0024] During the operation of the sheet palletizing equipment of this application, the feeding module 300 places the sheet material located at the picking position 110 onto the guiding mechanism 230 of the palletizing module 200. After the guiding mechanism 230 guides the sheet material's posture, the sheet material is automatically stacked onto the palletizing fixture 210 located at the palletizing position 120. When the palletizing fixture 210 is full of sheet material, i.e., when the stack is full, the driving mechanism 240 drives the clamping mechanism 220 to move from the palletizing position 120 to the fixture placement position 130, thereby driving the palletizing fixture 210. The material is moved to the fixture placement position 130, and then the palletizing fixture 210 on the clamping mechanism 220 is taken out by the fixture removal module 400. The empty palletizing fixture 210 is placed on the clamping mechanism 220 by the fixture removal module 400. After the palletizing fixture 210 is clamped and fixed by the clamping mechanism 220, the clamping mechanism 220 is driven by the drive mechanism 240 to move to the palletizing position 120, so that the palletizing fixture 210 moves below the guide mechanism 230. At this time, the feeding module 300 can stack the sheet material on the empty palletizing fixture 210. It can be seen from the above working process that this application first guides the posture of the sheet material through the guide mechanism 230, and after the guide mechanism 230 buffers, the sheet material is stacked on the palletizing fixture 210, which can effectively avoid misalignment and crushing caused by direct palletizing, thereby greatly improving the palletizing yield of the sheet material.

[0025] In a further embodiment of the present invention, the sheet palletizing equipment may also be provided with multiple palletizing modules 200 to reduce the time when the palletizing fixture 210 is changed, the feeding module 300 is in a non-working state. By setting up the palletizing module 200, the palletizing efficiency of the sheet can be effectively improved.

[0026] refer to Figure 3 and Figure 4 In some embodiments of the present invention, the clamping mechanism 220 includes a positioning seat 221, a first clamping member 222, a second clamping member 223, a transmission structure 225, and a first driver 224. The positioning seat 221 is provided with a positioning groove 221a, which has an intersecting first groove wall 221b and a second groove wall 221c. The first clamping member 222 cooperates with the first groove wall 221b to clamp the opposite ends of the palletizing fixture 210. The second clamping member 223 cooperates with the second groove wall 221c to clamp the other opposite ends of the palletizing fixture 210. The first driver 224 is connected to the first clamping member 222 and is used to drive the first clamping member 222 to move closer to or away from the positioning groove 221a. The first clamping member 222 is connected to the second clamping member 223 through the transmission structure 225 so that the second clamping member 223 and the first clamping member 222 can move away from the positioning groove 221a synchronously.

[0027] Understandably, when the palletizing fixture 210 is full and moves to the fixture placement position 130, the first driver 224 drives the first clamping member 222 away from the positioning groove 221a. The first clamping member 222, through the transmission structure 225, drives the second clamping member 223 away from the positioning groove 221a. The first clamping member 222 and the second clamping member 223 release the palletizing fixture 210 from the positioning groove 221a, and then the fixture removal module 400 removes the positioning fixture. After the palletizing fixture 210 is placed in the slot 221a, the unloaded palletizing fixture 210 is placed in the positioning slot 221a. The first driver 224 drives the first clamping member 222 to approach the positioning slot 221a. The first clamping member 222 clamps the palletizing fixture 210 with the first slot wall 221b. At the same time, the second clamping member 223 approaches the positioning slot 221a and clamps the palletizing fixture 210 with the second slot wall 221c, thereby achieving the clamping and fixing of the palletizing fixture 210.

[0028] like Figure 3 and Figure 4 As shown, in some embodiments, the transmission structure 225 includes a first abutting member 225a and a second abutting member 225b. The first abutting member 225a is connected to the first clamping member 222, and the second abutting member 225b is connected to the second clamping member 223. The first abutting member 225a is provided with an abutting inclined surface 225c. When the first driver 224 drives the first clamping member 222 away from the first groove wall 221b, the second abutting member 225b abuts against the abutting inclined surface 225c and moves away from the second groove wall 221c along the abutting inclined surface 225c, thereby driving the second clamping member 223 away from the second groove wall 221c. Specifically, the first groove wall 221b and the second groove wall 221c are perpendicular. Understandably, when the palletizing fixture 210 is full and moves to the fixture placement position 130, the first clamping member 222 is driven by the first driver 224 to move away from the first groove wall 221b in the horizontal direction. The first abutting member 225a abuts against the second abutting member 225b, and pushes the second abutting member 225b to move along the abutting slope 225c of the first abutting member 225a and away from the second groove wall 221c. This causes the second clamping member 223 connected to the second abutting member 225b to move away from the second groove wall 221c in the horizontal direction.

[0029] like Figure 3 and Figure 4As shown, in one embodiment, the clamping mechanism 220 further includes an elastic connector 226, which connects the second clamping member 223 and the positioning seat 221 respectively, and is used to provide an elastic force to the second clamping member 223 as it approaches the second groove wall 221c. It is understood that when the first driver 224 drives the first clamping member 222 to move horizontally away from the first groove wall 221b, the first abutment member 225a can overcome the elastic force applied to the second clamping member 223 by the elastic connector 226, thereby pushing the second abutment member 225b to move along the abutting slope 225c of the first abutment member 225a and away from the second groove wall 221c, so that the second clamping member 223 overcomes the elastic force applied by the elastic connector 226 and moves horizontally away from the second groove wall 221c. c. The elastic connector 226 stores elastic potential energy. When the first driver 224 drives the first clamping member 222 to approach the first groove wall 221b in the horizontal direction, the first abutting member 225a moves away from the second abutting member 225b, the elastic connector 226 releases elastic potential energy, and applies an elastic force close to the second groove wall 221c to the second clamping member 223, thereby causing the second clamping member 223 to approach the second groove wall 221c in the horizontal direction and cooperate with the second groove wall 221c to clamp the palletizing fixture 210.

[0030] refer to Figure 3 and Figure 5 In some embodiments of the present invention, the guiding mechanism 230 includes a guiding member 231. The guiding member 231 is provided with a guiding groove 231a adapted to the sheet material. The groove wall of the guiding groove 231a is provided with a guiding inclined surface 231b, which is used to guide the sheet material into the guiding groove 231a. It can be understood that when the feeding module 300 places the sheet material in the guiding groove 231a of the guiding member 231, it can first be guided by the guiding inclined surface 231b of the guiding groove 231a, and then pass through the guiding groove 231a adapted to the sheet material and stack it on the stacking fixture 210. By setting the guiding groove 231a, the accuracy requirements for feeding by the feeding module 300 are reduced, while ensuring the posture of the sheet material when it falls into the stacking fixture 210, thereby effectively preventing poor stacking caused by sheet material misalignment.

[0031] like Figure 3 and Figure 5As shown, in some embodiments, the guiding mechanism 230 further includes a first support member 232, a second support member 233, and a second driver 234. The first support member 232 and the second support member 233 are respectively used to support the opposite ends of the sheet located in the guiding groove 231a, and the second driver 234 is used to drive the first support member 232 and the second support member 233 to move closer to or away from the guiding groove 231a. Understandably, when the feeding module 300 places the sheet material in the guide groove 231a of the guide member 231, the driver drives the first support member 232 and the second support member 233 to move synchronously towards the guide groove 231a in the horizontal direction, so that the sheet material falls smoothly onto the first support member 232 and the second support member 233 along the guide groove 231a, thereby keeping the posture of the sheet material stacked in front of the palletizing fixture 210 consistent. Then, the second driver 234 drives the first support member 232 and the second support member 233 to move synchronously away from the guide groove 231a in the horizontal direction, so that the sheet material can fall smoothly and be stacked on the palletizing fixture 210, thereby effectively preventing the sheet material from not being able to be stacked smoothly on the palletizing fixture 210 due to different weights.

[0032] like Figure 3 and Figure 5 As shown, in some embodiments, the palletizing fixture 210 is provided with a positioning post 211 for passing through positioning holes on the sheet. The guiding mechanism 230 further includes a third driver 235 for driving the guiding member 231 to move vertically, so that the positioning post 211 of the palletizing fixture 210 located at the palletizing position 120 extends into or out of the guiding groove 231a. Specifically, the upper end of the positioning post 211 is provided with a chamfer 211a. Understandably, when the drive mechanism 240 drives the clamping mechanism 220 to move to the palletizing position 120, the palletizing fixture 210 on the clamping mechanism 220 is directly below the guide member 231. Then, the guide member 231 is driven to move downward by the third driver 235 so that the upper end of the positioning post 211 of the palletizing fixture 210 extends into the guide groove 231a. When the sheet falls along the guide groove 231a onto the first support member 232 and the second support member 233, the chamfer 211a of the positioning post 211 passes through the positioning hole of the sheet. Therefore, when the first support member 232 and the second support member 233 move away from the guide groove 231a, the chamfer 211a of the positioning post 211 can guide the sheet to be stably stacked on the palletizing fixture 210 along the positioning post 211, thereby improving the palletizing yield of the sheet.

[0033] Specifically, the first support member 232, the second support member 233, and the second driver 234 are all disposed on the guide member 231.

[0034] In some embodiments of the present invention, the guide member 231 is also provided with a through-beam optical fiber 236 to monitor the posture of the sheet in the guide groove 231a in real time, so as to avoid the sheet from being misaligned and accumulated, thereby causing damage to the sheet.

[0035] refer to Figure 1 , Figure 2 and Figure 6 In some embodiments of the present invention, the sheet palletizing equipment further includes an empty pallet lifting module 500, a full pallet lifting module 600, and a pallet transfer module 700. The frame 100 is also provided with a pallet placement position. The empty pallet lifting module 500 is used to transport the pallet loaded with the empty palletizing fixture 210 to the pallet placement position. The fixture removal module 400 is used to transfer the empty palletizing fixture 210 in the pallet placement position to the clamping mechanism 220 of the fixture placement position 130, and to transfer the full palletizing fixture 210 in the clamping module to the pallet in the pallet placement position. The pallet transfer module 700 is used to unload the full pallet in the pallet placement position to the full pallet lifting module 600.

[0036] Understandably, the empty pallet lifting module 500 transports a pallet containing multiple empty palletizing fixtures 210 to the pallet placement position. Then, the fixture removal module 400 transfers the empty palletizing fixtures 210 to the clamping mechanism 220 located at the fixture placement position 130. The drive mechanism 240 then moves the empty palletizing fixtures 210 to the palletizing position 120 for stacking sheets. When the empty palletizing fixtures 210 are full, the drive mechanism 240... The fully loaded palletizing fixture 210 is moved to the fixture placement position 130 by the drive module 400, and then the fully loaded palletizing fixture 210 is placed in the empty area of ​​the material tray by the fixture picking module 400. The above actions are repeated until the material tray is full of fully loaded palletizing fixture 210. Then the material tray is transferred to the full material tray lifting module 600 by the material tray transfer module 700, and then the material tray full of fully loaded palletizing fixture 210 is placed in the storage area by the full material tray lifting module 600.

[0037] refer to Figure 1 , Figure 2 and Figure 7 In some embodiments of the present invention, the sheet stacking equipment further includes an unwinding roller 800, a rewinding roller 900, a peeling module 1000, and a conveyor belt 1100. The unwinding roller 800 is used to unwind the strip with the sheet attached, the peeling module 1000 is used to peel the sheet off the strip, the conveyor belt 1100 is used to transport the peeled sheet to the picking position 110, and the rewinding roller 900 is used to rewind the strip. It is understood that the strip with the sheet attached is wound in the unwinding roller 800, unwound by the unwinding roller 800, and the reel moves to the peeling module 1000, where the sheet is peeled off the strip. The peeled sheet is then transported to the picking position 110 by the conveyor belt 1100, and the peeled strip is rewound by the rewinding roller 900.

[0038] refer to Figure 1 , Figure 2 and Figure 7 In a specific embodiment of the present invention, the peeling module 1000 includes a peeling platform 1010 and a guide block 1020. The peeling platform 1010 is provided with a vacuum adsorption hole 1011 for adsorbing the material strip. The peeling platform 1010 is provided with a peeling blade 1012. The guide block 1020 is located on the side of the peeling blade 1012 close to the conveyor belt 1100. The guide block 1020 is provided with a plurality of spaced guide grooves 1020a. The plurality of guide grooves 1020a can separate the peeled sheets and effectively prevent the sheets from being misaligned and stacked after peeling.

[0039] In a specific embodiment of the present invention, the feeding module 300 includes a parallel robot and an adsorption structure. The parallel robot picks up the sheet material on the conveyor belt 1100 through the adsorption structure. The jig module 400 includes a robotic arm and a gripper. The robotic arm drives the gripper to hold the positioning post 211 of the palletizing jig 210. The gripper uses a V-groove to grip the positioning post 211 to ensure consistency after gripping.

[0040] refer to Figure 1 and Figure 2 In some embodiments of the present invention, the sheet palletizing equipment further includes a defective product storage module 1200 and a detection module 1300. The detection module 1300 is used to detect whether the sheet is a good product. The feeding module 300 is electrically connected to the detection module 1300 and can transfer good sheets to the palletizing module 200 or defective sheets to the defective product storage module 1200 based on the detection result of the detection module 1300. It can be understood that after the peeling module 1000 peels the sheet from the conveyor belt, before the conveyor belt 1100 transports the sheet to the picking position 110, the detection module 1300, which is set above the conveyor belt 1100, will detect the sheet to determine whether it is a good or defective product. Then, the feeding module 300 places the good products in the palletizing module 200 for palletizing, or transfers the defective products to the defective product storage module 1200.

[0041] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
