[0002] Industrial robots are automated, programmable, and multifunctional mechanical devices used in manufacturing. They can perform tasks such as handling, assembly, welding, painting, grinding, and packaging. They are typically controlled by pre-programmed procedures or artificial intelligence technology to improve production efficiency, precision, and safety.

[0003] Existing industrial robot processing devices typically use specialized molds to clamp and position workpieces during operations such as stamping or drilling, before proceeding with further processing. This process often involves significant time intervals, reducing the processing efficiency of some workpieces by the industrial robot. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to provide an industrial robot processing device with adjustable function, which can complete the loading and unloading of workpieces by utilizing the time required for workpiece processing operations, thereby improving the processing efficiency of some workpieces of the industrial robot.

[0006] A support cylinder is located on the bottom side of the turntable. The interior of the support cylinder is connected to the interior of the corresponding circular hole and the interior of the corresponding piston groove through an air inlet and a connecting hole, respectively.

[0007] The drive mechanism, located inside the support cylinder, is used to drive the turntable to rotate and extract gas from the support cylinder.

[0008] Preferably, the support cylinder includes a cylinder body located below the turntable. A semi-circular sealing gasket is fixedly installed on the top side of the cylinder body, and the top side of the sealing gasket contacts the bottom side of the turntable. The air inlet and the connection hole are both located on the sealing gasket.

[0009] Preferably, the end of the piston rod furthest from the drive member is spherically shaped and inserted into a corresponding circular hole, and a pressure relief valve is fixedly installed through the outer peripheral wall of the cylinder.

[0011] Preferably, the connector includes a limiting groove located at the center of the bottom side of the turntable, and the driving end of the motor is fixedly equipped with a limiting block, wherein the outer edge of the top side of the limiting block is arc-shaped and inserted into the limiting groove.

[0012] Preferably, the bottom side of the turntable has an annular groove, which is fitted around the outer periphery of several circular holes. Several balls are rotatably mounted at equal intervals on the top side of the cylinder corresponding to the position of the annular groove, and the top of each ball is inserted into the annular groove and in contact with the inner wall of the annular groove.

[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] See also Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, an industrial robot processing device with an adjustable function is provided, including: a turntable 1, on the top side of which a plurality of circular holes 2 are equally spaced, and a plurality of piston grooves 3 are equally spaced on the inner wall of the circular holes 2, and a piston rod 4 is slidably mounted in the piston grooves 3.

[0029] The support cylinder 5 is located on the bottom side of the turntable 1. The interior of the support cylinder 5 is connected to the interior of the corresponding circular hole 2 and the interior of the corresponding piston groove 3 through the air inlet 7 and the connecting hole 8, respectively.

[0030] The drive mechanism 6, which is located inside the support cylinder 5, is used to drive the turntable 1 to rotate and extract gas from the support cylinder 5.

[0031] In this embodiment, when the improved industrial robot processing device is used, (please refer to...) Figure 1 As shown, a control host is installed on the outer wall of the support cylinder 5 (for the operation of the control device), please refer to... Figure 1 , Figure 2 and Figure 5 As shown, the drive mechanism 6 first starts to continuously extract gas from the support cylinder 5 so that a stable negative pressure chamber is formed inside the support cylinder 5.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3As shown, the operator then places the workpieces into the circular hole 2 in sequence. (The workpieces can be shells or outer shells, etc., with a flat bottom side. A soft pad can be placed on the inner bottom wall of the circular hole 2 to seal the gap between the bottom side of the workpiece and the inner bottom wall of the circular hole 2. The circular hole 2 has a T-shaped design when viewed from the front.) After the workpieces are placed, the drive mechanism 6 drives the intermittent turntable 1 to rotate. First, the workpiece will move to the position of the connecting hole 8. At this time, the piston groove 3 at this position is connected to the negative pressure chamber inside the support cylinder 5 through the connecting hole 8. Some of the gas in the piston groove 3 flows into the support cylinder 5 through the connecting hole 8. Inside the negative pressure chamber, a negative pressure chamber is simultaneously formed in the piston groove 3. (A guide hole communicating with the inside of the piston groove 3 is opened at the position corresponding to the connection hole 8 on the top side of the turntable 1 to introduce outside air into the piston groove 3, so as to avoid the formation of a negative pressure chamber in the piston groove 3 when the piston rod 4 slides out of the piston groove 3, thus applying a pulling force towards the outside of the piston groove 3 to the piston rod 4, so that part of the piston rod 4 extends out of the piston groove 3, thereby moving the workpiece to the center position of the circular hole 2 through the contact between the piston rod 4 and the workpiece in different directions.

[0033] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, after the workpiece position adjustment is completed, the workpiece is then moved to the position of the air inlet 7. At this time, the inside of the circular hole 2 is connected to the negative pressure chamber inside the support cylinder 5, so that part of the gas in the bottom opening of the circular hole 2 flows into the support cylinder 5 through the air inlet 7, thereby forming a corresponding negative pressure chamber in the bottom opening of the circular hole 2, which in turn applies a downward suction force to the workpiece, so that the bottom side plane of the workpiece is in close contact with the inner wall of the circular groove, thereby generating a frictional force of corresponding strength between the workpiece and the inner wall of the circular hole 2, thereby adsorbing and fixing the workpiece at the center position inside the circular hole 2.

[0034] As the turntable 1 rotates, when the workpiece moves between the air inlet 7 and the connecting hole 8, the external gas can flow directly into the bottom opening of the round hole 2 and into the piston groove 3 through the connecting hole 8, so as to automatically release the workpiece from the adsorption and clamping state. At this time, the processed workpiece can be directly taken out from the round hole 2. (It should be noted that a spring can also be installed in the piston hole to apply a thrust towards the piston groove 3 to the piston rod 4, so that when the external gas flows into the piston groove 3, it will automatically push the piston rod 4 into the piston groove 3.)

[0035] In summary, during the processing of workpieces by the industrial robot, the rotation of the turntable 1 adjusts the position of the workpiece within the circular hole 2, followed by the adsorption and fixation of the workpiece. Through workpiece clamping and adsorption fixation, the workpiece is stably constrained to the corresponding position on the support cylinder 5 for processing. Finally, after the workpiece is processed, as the turntable 1 continues to rotate, the adsorption and clamping fixation of the workpiece can be automatically released. The operator can use the time required for workpiece processing to complete the loading and unloading of the workpiece, thereby improving the processing efficiency of some workpieces by the industrial robot.

[0036] This improved industrial robot processing device does not require the operator to precisely place the workpiece in a specific position during use. It can automatically adjust the position of the workpiece, and the distance between the workpiece loading position and the processing tool is large, resulting in high safety.

[0037] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 4 and Figure 5 As shown, the support cylinder 5 includes a cylinder body 51, which is located below the turntable 1. A semi-circular sealing gasket 52 is fixedly installed on the top side of the cylinder body 51, and the air inlet 7 and the connecting hole 8 are both located on the sealing gasket 52 at the junction of the top side of the sealing gasket 52 and the bottom side of the turntable 1.

[0038] In this embodiment, please refer to Figure 1 , Figure 4 and Figure 5 As shown, during the rotation of turntable 1, since the air inlet 7 and the connecting hole 8 are located on the sealing gasket 52, when the round hole 2 moves to the position of the air inlet 7 or the connecting hole 8, (please refer to...) Figure 2 , Figure 3 and Figure 4 As shown, the connection hole 8 is divided into two parts. The top connection hole 8 is located on the turntable 1, and the bottom connection hole 8 is located on the sealing gasket 52 and the cylinder 51. The sealing gasket 52 seals the gap between the turntable 1 and the top side of the cylinder 51, so that outside air will not flow into the cylinder 51, piston groove 3 or bottom opening of round hole 2 through the connection hole 8 or air inlet 7, which would affect the formation of negative pressure chamber in piston groove 3 or bottom opening of round hole 2, thus affecting the use of the device.

[0039] When the round hole 2 is moved away from the position of the air inlet 7, due to the spacing of the sealing gasket 52, there is a gap of corresponding size between the bottom side of the turntable 1 and the top side of the cylinder 51. At this time, the outside air flows into the bottom opening of the round hole 2 or the top connecting hole 8 through the gap between the turntable 1 and the cylinder 51, so as to automatically release the negative pressure state in the bottom opening of the round hole 2 or the piston groove 3.

[0040] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the end of the piston rod 4 furthest from the drive component is spherically shaped and inserted into the corresponding circular hole 2. A pressure relief valve 11 is fixedly installed through the outer peripheral wall of the cylinder 51.

[0041] In this embodiment, please refer to Figure 2 As shown, when the gas is extracted from the support cylinder 5, a negative pressure chamber with gradually increasing strength is formed in the cylinder 51 as the gas is lost, and the pressure difference across the pressure relief valve 11 gradually increases. When the pressure difference across the pressure relief valve 11 reaches the threshold, outside air flows into the cylinder 51 through the pressure relief valve 11 to replenish the gas lost in the cylinder 51, so that the negative pressure intensity in the cylinder 51 is always maintained at the corresponding state.

[0042] After the workpiece is processed, the drive mechanism 6 stops extracting gas from the cylinder 51 and continues to drive the turntable 1 to rotate. At this time, the workpiece is no longer placed in the round hole 2. When the round hole 2 moves to the position of the air inlet 7, the outside gas flows into the cylinder 51 through the corresponding round hole 2 and air inlet 7, which can relieve the negative pressure state in the cylinder 51. Finally, the operation of the drive mechanism 6 is stopped.

[0043] Please refer to Figure 2 and Figure 3 As shown, the hemispherical end of the piston rod 4 can prevent the sharp outer edge of the piston rod 4 from colliding with the workpiece and causing damage to the workpiece surface. (A soft block can also be fixedly installed at the end of the piston rod 4 for clamping and fixing the workpiece.)

[0044] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 4 and Figure 5 As shown, the drive mechanism 6 includes a motor 61, which is located in the inner hole of the cylinder 51 and is fixedly connected to the turntable 1 through a connector 63. An air pump 62 is located below the motor 61, and the air pump 62 is fixedly inserted into the cylinder 51. Both the motor 61 and the air pump 62 are fixedly connected to the inner wall of the cylinder 51 through a connecting rod.

[0045] In this embodiment, please refer to Figure 2 , Figure 4 and Figure 5 As shown, during operation, the control unit drives the turntable 1 to rotate intermittently by controlling the start and stop of motor 61 (motor 61 is a servo motor 61). Simultaneously, the operating air pump 62 continuously extracts gas from the cylinder 51. (Please refer to...) Figure 1 and Figure 5As shown, several support legs are fixedly installed on the bottom side of the cylinder 51 to facilitate the connection and fixation between the cylinder 51 and the platform by bolts, and to form a gap of corresponding size between the bottom side of the cylinder 51 and the platform, so that the gas discharged by the air pump 62 can be discharged through the gap between the bottom side of the cylinder 51 and the platform.

[0046] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 5 As shown, the connector 63 includes a limiting groove 631, which is opened at the center of the bottom side of the turntable 1. The driving end of the motor 61 is fixedly equipped with a limiting block 632, and the outer edge of the top side of the limiting block 632 is arc-shaped and inserted into the limiting groove 631.

[0047] In this embodiment, please refer to Figure 2 and Figure 5 As shown, when the motor 61 starts, due to the mutual abutment between the limiting block 632 and the inner wall of the limiting groove 631 (the limiting block 632 can be a quadrangular rod or a hexagonal rod or other multi-faceted rod, and the limiting groove 631 can be a multi-faceted groove set in the shape of a quadrangular rod or a hexagonal rod);

[0048] The operator can move the turntable 1 upwards, which will allow the limit block 632 to slide out of the limit groove 631, thereby allowing the turntable 1 to be removed directly from the support cylinder 5, so as to facilitate the replacement of the damaged turntable 1 or the damaged sealing gasket 52.

[0049] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, an annular groove 9 is provided on the bottom side of the turntable 1, and the annular groove 9 is fitted on the outer periphery of several circular holes 2. Several balls 10 are rotatably installed on the top side of the cylinder 51 at equal intervals corresponding to the position of the annular groove 9, and the top of each ball 10 is inserted into the annular groove 9 and connected to the inner wall of the annular groove 9.

[0050] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 As shown, when the turntable 1 rotates, the balls 10 roll synchronously within the annular groove 9, thereby applying a constraint limit to the turntable 1 through the contact between the balls 10 and the inner wall of the annular groove 9, and providing stable support to the turntable 1 while almost increasing the resistance encountered when the turntable 1 rotates, so that the turntable 1 can be stably kept in a straight position and rotated at the corresponding position on the top side of the support cylinder 5, avoiding positional or angular displacement of the turntable 1 that would affect the use of the device;

[0051] When the turntable 1 is removed from the support cylinder 5, (the bottom third of the ball bearing 10 is inserted into the top wall of the cylinder 51 and rotates and connects with the cylinder 51), the ball bearing 10 can be directly removed from the cylinder 51, which facilitates the replacement of worn ball bearing 10.

[0052] Working principle: When this improved industrial robot processing device is in use, the rotation of the turntable 1 moves the workpiece in the circular hole 2 sequentially to the connecting hole 8, the air inlet 7, and between the connecting hole 8 and the air inlet 7. When the workpiece moves to the position of the connecting hole 8, the piston rod 4 completes the clamping limit and position adjustment of the workpiece from multiple angles on the outside of the workpiece. When the workpiece moves to the position of the air inlet 7, the adsorption limit of the workpiece is completed. When the workpiece moves between the connecting hole 8 and the air inlet 7, the clamping limit and adsorption fixation of the processed workpiece are released, so that the operator can complete the loading and unloading operations of the workpiece during the processing time, which greatly improves the processing efficiency of some workpieces of the industrial robot.

[0053] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0054] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
