Description

Technical Field

[0001] The utility model relates to the field of grinding equipment, in particular to a pallet feeding and discharging system of a robot grinding equipment. Background Art

[0002] During the processing of existing workpieces, grinding is usually required for polishing, deburring and other treatments. And some existing grinding equipment will be linked with components such as manipulators, and the manipulators are used for loading and unloading the workpieces to improve the efficiency during the grinding process of the workpieces.

[0003] However, there are certain problems in the linkage system between the existing grinding equipment and the manipulator: ① Since the manipulator requires a large operating space, in order to avoid interference between the manipulator and the storage system, the interval space in the storage system needs to be set larger to ensure that the manipulator can stably enter the storage space for loading and unloading, resulting in the occupation of the storage volume of the storage space; ② When the existing manipulator is used for loading and unloading, it is usually used to transfer the workpieces between the storage system and the grinding equipment, which makes the storage system and the grinding equipment unable to be spaced far apart, resulting in their mutual binding and being unfavorable for the space allocation of the factory. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a pallet feeding and discharging system of a robot grinding equipment, which improves the convenience of feeding and discharging of workpiece grinding and increases the storage space of the workpieces.

[0005] To solve the above technical problems, the utility model provides a pallet feeding and discharging system of a robot grinding equipment, which includes a conveying component and a storage component. The storage component includes two relatively arranged storage assemblies. The storage assembly includes a plurality of first pallets arranged at intervals in the height direction, a plurality of second pallets arranged at intervals in the height direction, and storage slots opened on the first pallets and the second pallets. The plurality of first pallets and the plurality of second pallets are arranged in a staggered manner. And a first driving hole and a first guiding hole are opened on the side of the first pallet, a second driving hole and a second guiding hole are opened on the side of the second pallet. A first driving shaft passes through the first driving hole and the second guiding hole in sequence, and a second driving shaft passes through the second driving hole and the first guiding hole in sequence, so that when the first driving shaft rotates, the plurality of first pallets are lifted and lowered, and when the second driving shaft rotates, the plurality of second pallets are lifted and lowered.

[0006] Further, the first driving hole and the first driving shaft are in threaded fit, and the second driving hole and the second driving shaft are in threaded fit.

[0007] Further, a first guiding ring is rotatably arranged in the first guiding hole, a second guiding ring is rotatably arranged in the second guiding hole, and the first guiding ring is in moving fit with the second driving shaft, and the second guiding ring is in moving fit with the first driving shaft.

[0008] Furthermore, both ends of the first drive shaft and the second drive shaft are rotatably connected to the adjustment disc, and the adjustment disc is rotatably mounted on the base. When the adjustment disc rotates relative to the base, adjacent storage components can be switched for use.

[0009] Furthermore, the conveying component includes a lifting track and a horizontal track. One side of the horizontal track is movably engaged with the lifting track through a moving block. The storage rack is movably mounted on the horizontal track, and a storage groove is provided on the storage rack.

[0010] Furthermore, a plurality of negative pressure holes are provided at the bottom of the storage groove, and the plurality of negative pressure holes are all communicated to the negative pressure cavity.

[0011] Furthermore, one side of the negative pressure cavity has an opening.

[0012] Furthermore, a clamping plate is detachably provided at the opening, and the end of the clamping plate extends to the inside of the negative pressure cavity to block the plurality of negative pressure holes with the clamping plate.

[0013] The beneficial effects of the present utility model are as follows: When loading and unloading workpieces during grinding, the manipulator conveys the workpieces in the storage component to the conveying component, and the conveying component conveys the workpieces to the grinding equipment. Similarly, the workpieces at the grinding equipment are conveyed to the storage component for storage. In this process, there is no need to closely connect the storage component and the grinding equipment, which improves the convenience of the factory's block division of various equipment. At the same time, when storing workpieces, the workpieces can be stored in the storage grooves of the first tray or the second tray. When the manipulator moves to the storage groove to load and unload workpieces, first, the first drive shaft or the second drive shaft rotates to drive the first tray or the second tray to lift. When a plurality of first trays synchronously descend, the distance between the first tray and the upper second tray increases, thereby increasing the insertion space of the manipulator and ensuring that the manipulator can stably load and unload workpieces. After the manipulator is used, a plurality of first trays synchronously rise, so that the distance between the first tray and the second tray is reset. At this time, the storage space can be utilized to the maximum extent to improve the storage limit of workpieces. Similarly, the second tray can be synchronously lifted and lowered through the second drive shaft. Description of the Drawings

[0021] Such as Figures 1 - 3As described above, the present utility model provides a tray loading and unloading system for a robot grinding device, which includes a conveying component and a storage component. The storage component includes two relatively arranged storage assemblies. The storage assembly includes a plurality of first trays 1 arranged at intervals in the height direction, a plurality of second trays 2 arranged at intervals in the height direction, and storage slots 3 opened on the first trays 1 and the second trays 2. The plurality of first trays 1 and the plurality of second trays 2 are arranged in an alternating manner. A first driving hole 4 and a first guiding hole 5 are opened on the side of the first tray 1, and a second driving hole 6 and a second guiding hole 7 are opened on the side of the second tray 2. A first driving shaft 8 sequentially passes through the first driving hole 4 and the second guiding hole 7, and a second driving shaft 9 sequentially passes through the second driving hole 6 and the first guiding hole 5. When the first driving shaft 8 rotates, the plurality of first trays 1 are lifted and lowered. When the second driving shaft 9 rotates, the plurality of second trays 2 are lifted and lowered.

[0022] When loading and unloading workpieces during grinding, the manipulator transports the workpieces in the storage component to the conveying component, and the conveying component transports the workpieces to the grinding device. Similarly, the workpieces at the grinding device are transported to the storage component for storage. In this process, there is no need to closely connect the storage component with the grinding device, which improves the convenience of the factory's block division of various devices. At the same time, when storing workpieces, the workpieces can be stored in the storage slots 3 of the first trays 1 or the second trays 2. When the manipulator moves to the storage slots 3 to load and unload workpieces, first, the first driving shaft 8 or the second driving shaft 9 rotates to drive the first tray 1 or the second tray 2 to lift and lower. When the plurality of first trays 1 synchronously descend, the distance between the first tray 1 and the upper-layer second tray 2 increases, thereby increasing the insertion space of the manipulator and ensuring that the manipulator can stably load and unload workpieces. After the manipulator is used, the plurality of first trays 1 synchronously rise, so that the distance between the first tray 1 and the second tray 2 is reset. At this time, the storage space can be utilized to the maximum extent to improve the storage limit of workpieces. Similarly, the second tray 2 can be synchronously lifted and lowered through the second driving shaft 9.

[0023] In an embodiment of this solution, both the first driving shaft 8 and the second driving shaft 9 are controlled to rotate by a servo motor.

[0024] Preferably, the first driving hole 4 and the first driving shaft 8 are in threaded fit, and the second driving hole 6 and the second driving shaft 9 are in threaded fit.

[0025] Specifically, through the threaded fit method, the first driving shaft 8 can drive the position of the first driving hole 4 to lift and lower through the thread, and the second driving shaft 9 can drive the position of the second driving hole 6 to lift and lower through the thread, so as to ensure the stable lifting and lowering of the first tray 1 and the second tray 2.

[0026] Preferably, a first guiding ring 10 is rotatably arranged in the first guiding hole 5, and a second guiding ring 11 is rotatably arranged in the second guiding hole 7. The first guiding ring 10 is in movable cooperation with the second driving shaft 9, and the second guiding ring 11 is in movable cooperation with the first driving shaft 8.

[0027] Specifically, when the first driving shaft 8 drives the first tray 1 to move up and down, through the movable cooperation between the first guiding ring 10 and the second driving shaft 9, the position of the first guiding ring 10 can move up and down along the second driving shaft 9, so that the second driving shaft 9 plays a role in guiding and limiting the first tray 1. When the second driving shaft 9 drives the second tray 2 to move up and down, due to the rotational cooperation between the first guiding ring 10 and the first guiding hole 5, the second driving shaft 9 will not affect the first tray 1. Similarly, the second tray 2 can also be guided for lifting through the cooperation between the second guiding ring 11 and the first driving shaft 8.

[0028] In an embodiment of this solution, chutes are axially formed on the outer sides of the first driving shaft 8 and the second driving shaft 9, and sliders corresponding to the chutes are provided on the inner sides of the first guiding ring 10 and the second guiding ring 11, so that the sliders can move relative to the chutes to ensure the guiding effect of the first guiding ring 10 and the second guiding ring 11.

[0029] Preferably, the ends of the first driving shaft 8 and the second driving shaft 9 are both rotatably connected to an adjusting disc 12, and the adjusting disc 12 is rotatably installed on the base 13. When the adjusting disc 12 rotates relative to the base 13, adjacent storage components are switched for use.

[0030] Specifically, by rotating the adjusting disc 12 relative to the base 13, the adjusting disc 12 drives a plurality of storage components thereon to rotate, thereby adjusting the relative positions of different storage components and the conveying components, and ensuring that each storage component can perform loading and unloading operations.

[0031] In an embodiment of this solution, a motor is built in the base 13, and the motor controls the adjusting disc 12 to rotate.

[0032] Preferably, the conveying component includes a lifting track 14 and a horizontal track 15. One side of the horizontal track 15 is in movable cooperation with the lifting track 14 through a moving block 16. A storage rack 17 is movably installed on the horizontal track 15, and a storage slot 18 is formed on the storage rack 17.

[0033] Specifically, the lifting of the storage rack 17 is controlled by the lifting track 14, and the horizontal movement of the storage rack 17 is controlled by the horizontal track 15. Then, under the synchronous action of the lifting track 14 and the horizontal track 15, the storage rack 17 can be moved to any position on the plane level to ensure the convenience of loading and unloading on the storage rack 17. During the process of conveying the workpiece through the conveying component, the workpiece is placed in the storage groove 18 to ensure that the workpiece can be moved to any position along with the storage rack 17.

[0034] Among them, both the lifting track 14 and the horizontal track 15 are controlled by using electric tracks or the form of a motor cooperating with a lead screw drive.

[0035] Preferably, a plurality of negative pressure holes 19 are opened at the bottom of the storage groove 18, and the plurality of negative pressure holes 19 are all communicated to the negative pressure chamber 20.

[0036] Specifically, when the workpiece is placed in the storage groove 18, the negative pressure chamber 20 generates negative pressure suction, so that negative pressure suction forces are generated at the positions of the respective negative pressure holes 19 at the bottom of the storage groove 18, and then each workpiece is adsorbed at the negative pressure holes 19 to improve the stability of the workpiece during the conveying process along with the storage rack 17.

[0037] Preferably, an opening 21 is provided on one side of the negative pressure chamber 20.

[0038] Specifically, an external negative pressure device is connected to the opening 21, so that the negative pressure device can provide negative pressure suction to the negative pressure chamber 20 to ensure that the negative pressure suction force at the negative pressure holes 19 is stable enough.

[0039] Preferably, a clamping plate 22 is detachably arranged at the opening 21, and the end of the clamping plate 22 extends to the inside of the negative pressure chamber 20, so that the clamping plate 22 blocks the plurality of negative pressure holes 19.

[0040] Specifically, when the negative pressure holes 19 are not in use or the workpiece is easily sucked into the inside of the negative pressure holes 19, the clamping plate 22 is inserted into the negative pressure chamber 20, so that the clamping plate 22 blocks each negative pressure hole 19. At the same time, the clamping plate 22 can be disassembled from the negative pressure chamber 20 subsequently to facilitate the reuse of the negative pressure holes 19.

[0041] The present utility model is not limited to the above-mentioned best implementation manner. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to the present application, it falls within the protection scope of the present utility model.
