Description

Technical Field

[0001] This utility model relates to the field of industrial processing equipment, and in particular to a workpiece loading rack for a closable workpiece processing machine and a closable workpiece processing machine. Background Technology

[0002] For example, enclosed machining equipment integrating processing robots and equipped with external enclosures is increasingly used as an automated processing system due to its high efficiency, safety, and environmental friendliness. Currently, when loading and unloading workpieces into such equipment, operators typically use trolleys to transport the workpieces and manually load them into the processing station inside the equipment. After processing, the workpieces are manually unloaded from the processing station and transported away. Loading and unloading small workpieces is not a problem. However, when processing large workpieces, such as those exceeding 100kg, even with multiple operators working together, loading and unloading is time-consuming and labor-intensive.

[0003] Therefore, a suitable workpiece loading device is needed to assist in loading and unloading various workpieces onto and from the processing equipment. Utility Model Content

[0004] The purpose of this invention is to provide a workpiece loading rack for a closable workpiece processing machine and a closable workpiece processing machine using the workpiece loading rack, so as to at least partially solve the problems existing in the prior art.

[0005] According to a first aspect of the present invention, a workpiece loading rack for a closable workpiece processing machine is provided, the workpiece loading rack comprising at least:

[0006] A support base is fixedly installed inside the enclosed workpiece processing machine;

[0007] A rotary telescopic arm assembly, rotatably mounted on the support base and adapted to perform swinging and telescopic movements within the encloseable workpiece processing machine; and

[0008] An execution component is configured to load, unload, and lift workpieces at the working end of the rotary telescopic arm assembly.

[0009] According to the first aspect of this utility model, a workpiece loading rack for a closable workpiece processing machine can assist in transporting workpieces from the workpiece loading position to the workpiece loading position by means of the swinging and telescopic movements of the rotating telescopic arm assembly of the workpiece loading rack installed in the closable workpiece processing machine, as well as the loading, unloading, and lifting of workpieces by the actuating components. This saves labor costs and space, and at the same time, it easily avoids interference between the workpiece or workpiece loading rack and other devices or components in the closable workpiece processing machine during loading, unloading, and transportation.

[0010] According to an optional embodiment of the present invention, the rotary telescopic arm assembly includes a rotary support portion and a telescopic arm. The rotary support portion is rotatably mounted on the support base and is adapted to drive the telescopic arm to perform a horizontal swinging motion by rotation. The telescopic arm is configured to perform a horizontal telescopic motion between a retracted position and an extended position. With this embodiment, multiple spatial positions can be reached by means of the easily achievable and controllable horizontal swinging and telescopic motion of the telescopic arm.

[0011] According to an optional embodiment of the present invention, the telescopic arm is configured to swing within an angular range at least between the workpiece loading position and the workpiece loading position for processing the workpiece within the encloseable workpiece processing machine. With this embodiment, the workpiece can be transported within the workpiece processing machine by means of the telescopic arm swinging within the angular range.

[0012] According to an optional embodiment of the present invention, the rotary telescopic arm assembly further includes a telescopic drive device for driving the telescopic arm to perform telescopic movements and a rotary drive device for driving the rotary support portion to rotate. This embodiment enables the telescopic arm to perform swinging and telescopic movements.

[0013] According to an optional embodiment of the present invention, the telescopic arm's telescopic distance between the retracted position and the extended position is greater than or equal to the larger of a first horizontal distance and a second horizontal distance. The first horizontal distance is the horizontal distance between the working end of the telescopic arm in the retracted position and the workpiece loading position when the telescopic arm is facing the workpiece loading position of the encloseable workpiece processing machine. The second horizontal distance is the horizontal distance between the working end of the telescopic arm in the retracted position and the workpiece loading position when the telescopic arm is facing the workpiece loading position within the encloseable workpiece processing machine. This embodiment ensures that the working end of the telescopic arm can reach at least the farther position between the workpiece loading position and the workpiece loading position, thus ensuring the completion of the workpiece loading operation.

[0014] According to an optional embodiment of this utility model, the workpiece loading position is located outside the encloseable workpiece processing machine. With this embodiment, the working end of the telescopic arm can reach the workpiece loading position outside the workpiece processing machine, allowing operators to load the workpiece onto the workpiece loading rack outside the workpiece processing machine, further saving manpower.

[0015] According to an optional embodiment of this utility model, the telescopic arm is a scissor-type telescopic arm, comprising a plurality of scissor units hinged sequentially. Each scissor unit includes two hinged arms, which are hinged to each other at their respective midpoints via a rotation axis. Both ends of each hinged arm are hinged ends, and adjacent scissor units are hinged to each other via two adjacent pairs of hinged ends. Through this embodiment, by utilizing the characteristics of the scissor structure, a telescopic arm with a large telescopic range and a small footprint can be achieved.

[0016] According to an optional embodiment of the present invention, the rotary support portion forms a telescopic arm mounting plate, and the telescopic arm mounting plate forms a hinge structure and a slide rail structure. One of the two hinge ends of the mounting end opposite to the working end of the scissor-type telescopic arm is hinged to the hinge structure, and the other hinge end is slidably mounted within the slide rail structure, adapted to extend or retract the scissor-type telescopic arm by changing its position within the slide rail structure. With this embodiment, the telescopic movement of the scissor-type telescopic arm can be realized.

[0017] According to an optional embodiment of the present invention, the working end of the scissor-type telescopic boom is provided with a slide rail and a slide arm. One end of the slide rail is hinged to one hinged end of an adjacent scissor unit, and one end of the slide arm is hinged to the other hinged end of an adjacent scissor unit. The other end of the slide arm is slidably mounted in a groove in the slide rail. The slide rail and the slide arm are configured such that the slide rail remains horizontal from the retracted position to the extended position. This embodiment achieves a stable working end for the telescopic boom.

[0018] According to an optional embodiment of the present invention, the telescopic arm is a sliding telescopic arm, which includes at least two telescopic arm segments that are slidably nested. This embodiment enables the realization of a telescopic arm with a simple structure.

[0019] According to an optional embodiment of the present invention, the actuating component includes a drive source, a transmission component, and an end effector. The end effector is configured to load and unload workpieces, and the drive source is configured to drive the end effector to perform lifting and lowering movements via the transmission component. The drive source and the transmission component are mounted on the rotary support portion or working end of the rotary telescopic arm assembly. This embodiment enables the loading, unloading, and lifting operations of workpieces using the actuating component, and the drive source and transmission component can be installed in appropriate positions according to actual configuration needs.

[0020] According to an optional embodiment of the present invention, the support base is a column-type support base installed in the base or on the ground inside the enclosed workpiece processing machine. This embodiment, compared to a structure where the workpiece loading rack is installed on the wall of the workpiece processing machine, eliminates the need to reinforce the load-bearing capacity of the workpiece processing machine wall, saving costs and providing more stable support.

[0021] According to an optional embodiment of the present invention, the support base is installed at a corner within the encloseable workpiece processing machine. This embodiment further avoids interference between the workpiece loading rack and other devices or components within the workpiece processing machine, and also allows the telescopic arm of the workpiece loading rack to easily reach more positions through simple movements.

[0022] According to a second aspect of the present invention, a closable workpiece processing machine is provided, the closable workpiece processing machine including at least the workpiece loading rack for the closable workpiece processing machine as described in the first aspect of the present invention.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the scope of protection of the present utility model.

[0053] Figure 1 A top view of an encloseable workpiece processing machine 200 with a workpiece loading rack 100 for an encloseable workpiece processing machine 200 is shown schematically according to an exemplary embodiment of the present invention. Figure 2 The swing motion of a workpiece loading rack 100 for a closable workpiece processing machine 200 according to an exemplary embodiment of the present invention is schematically shown. Figure 3 The diagram schematically illustrates the extended position of the workpiece loading rack 100 for a closable workpiece processing machine 200 according to an exemplary embodiment of the present invention. Figure 4 The diagram schematically illustrates the retracted position of a workpiece loading rack 100 for a closable workpiece processing machine 200 according to an exemplary embodiment of the present invention. Figure 5 The diagram schematically illustrates the state in which the working end of the workpiece loading rack 100 for a closable workpiece processing machine 200 is in the workpiece loading position 201, according to an exemplary embodiment of the present invention. Figure 6 The diagram schematically illustrates a workpiece loading rack 100 for a closable workpiece processing machine 200 in an exemplary embodiment of the present invention, with the working end in the workpiece loading position 202. Figure 7 The diagram schematically illustrates a workpiece loading rack 100 for a closable workpiece processing machine 200 according to an exemplary embodiment of the present invention in a standby state.

[0054] like Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, an exemplary embodiment of the present invention discloses a closable workpiece processing machine 200 having a closable processing chamber and a processing operation device 210, such as a welding robot, located within the processing chamber. The processing operation device 210 has a certain operating space 203, which is the space range that the processing operation device 210 may occupy during the processing process. The workpiece processing station, i.e., the loading position 202 of the workpiece to be processed within the processing chamber of the workpiece processing machine 200, is located within the operating space 203, and the processing operation device 210 performs processing operations on the workpiece within the workpiece loading position 202. Furthermore, to facilitate the operator's loading operation from outside the workpiece processing machine 200 to the workpiece loading rack 100, the workpiece loading position 201 of the workpiece to be processed is located outside the processing chamber of the workpiece processing machine 200, preferably outside the door of the processing chamber, particularly as shown in the example below. Figure 5 As shown.

[0055] like Figure 3 and Figure 4 As shown, a workpiece loading rack 100 for a closable workpiece processing machine 200 according to an exemplary embodiment of the present invention includes at least: a support base 1, which is fixedly installed inside the closable workpiece processing machine 200; and a rotary telescopic arm assembly 2, which is rotatably installed on the support base 1 and adapted to perform swinging motion (e.g., within the closable workpiece processing machine 200) Figure 2 (Exemplary example shown) and telescopic movement; and an execution component 3, which is configured to load, unload, and lift workpieces at the working end of the rotary telescopic arm assembly 2. Thus, through the swinging and telescopic movements of the rotary telescopic arm assembly 2, in conjunction with the lifting movement of the execution component 3, the workpiece loading rack 100 can transport workpieces to various positions in space, easily achieving automatic loading of workpieces to the workpiece processing machine 200. Furthermore, compared to the construction of a fixed-length lifting arm, the rotary telescopic arm assembly 2, capable of telescopic movement, can avoid other equipment and components within the workpiece processing machine 200 during operation, particularly avoiding the processing operation equipment 210, thereby preventing equipment damage or impact on processing performance.

[0056] According to a preferred exemplary embodiment, the rotary telescopic arm assembly 2 includes a rotary support portion 21 and a telescopic arm. The rotary support portion 21 is rotatably mounted on the support base 1 and is adapted to drive the telescopic arm to perform a horizontal swinging motion by rotation. The telescopic arm is configured to perform a horizontal telescopic motion between a retracted position and an extended position.

[0057] According to a preferred exemplary embodiment, the telescopic arm is configured to swing within an angular range between the workpiece loading position 201 of the enclosed workpiece processing machine 200 and the workpiece loading position 202 for processing the workpiece within the enclosed workpiece processing machine 200.

[0058] According to a preferred exemplary embodiment, the rotary telescopic arm assembly 2 further includes a telescopic drive device for driving the telescopic arm to perform telescopic movements and a rotary drive device for driving the rotary support portion 21 to rotate.

[0059] According to a preferred exemplary embodiment, the telescopic arm's telescopic distance between its retracted and extended positions is greater than or equal to the larger of a first horizontal distance and a second horizontal distance. The first horizontal distance is the horizontal distance between the working end of the telescopic arm in its retracted position and the workpiece loading position 201 when the telescopic arm is facing the workpiece loading position 201 of the encloseable workpiece processing machine 200. The second horizontal distance is the horizontal distance between the working end of the telescopic arm in its retracted position and the workpiece loading position 202 when the telescopic arm is facing the workpiece loading position 202 within the encloseable workpiece processing machine 200. This ensures that the working end of the telescopic arm can reach vertically above the workpiece loading position 201 and the workpiece loading position 202 through swinging and telescopic extension, thereby achieving workpiece transport and loading.

[0060] According to a preferred exemplary embodiment, such as Figure 3 and Figure 4 As shown, the telescopic boom is a scissor-type telescopic boom 22, which includes multiple scissor units that are hinged in sequence. Each scissor unit includes two hinged arms 221 and 222. The two hinged arms 221 and 222 are hinged to each other at their respective middle parts by a rotating shaft, and both ends of each hinged arm are hinged ends. Adjacent scissor units are hinged to each other through two adjacent pairs of hinged ends.

[0061] According to a preferred exemplary embodiment, the rotary support portion 21 is formed with a telescopic arm mounting plate 211, on which a hinge structure 212 and a slide rail structure 213 are formed. One of a pair of hinge ends of the mounting end opposite to the working end of the scissor telescopic arm 22 is hinged to the hinge structure 212, and the other hinge end is slidably mounted in the slide rail structure 213 to be adapted to extend or retract the scissor telescopic arm 22 by changing its position in the slide rail structure 213.

[0062] According to a preferred exemplary embodiment, the working end of the scissor telescopic boom 22 is provided with a slide rail 223 and a slide arm 224. One end of the slide rail 223 is hinged to one hinged end of an adjacent scissor unit, and one end of the slide arm 224 is hinged to the other hinged end of an adjacent scissor unit. The other end of the slide arm 224 is slidably mounted in a groove in the slide rail 223. The slide rail 223 and the slide arm 224 are configured such that the slide rail 223 remains in a horizontal position from the retracted position to the extended position.

[0063] According to another preferred exemplary embodiment, the telescopic arm is a sliding telescopic arm, which includes at least two telescopic arm segments that are slidably nested.

[0064] According to a preferred exemplary embodiment, the execution component 3 includes a drive source 31, a transmission component 32, and an end working mechanism 33. The end working mechanism 33 is configured to load and unload workpieces to be processed. The drive source 31 is configured to drive the end working mechanism 33 to perform lifting and lowering movements by means of the transmission component 32. The drive source 31 and the transmission component 32 are mounted on the rotary support portion 21 or the working end of the rotary telescopic arm assembly 2.

[0065] According to a preferred exemplary embodiment, the support base 1 is a column-type support base installed in the base or ground of the enclosed workpiece processing machine 200.

[0066] According to a preferred exemplary embodiment, the support base 1 is installed at a corner within the enclosed workpiece processing machine 200.

[0067] Using the workpiece loading rack 100 according to an embodiment of the present invention, such as Figures 5 to 7 As shown, when loading a workpiece to be processed into the workpiece loading position 202 inside the enclosed workpiece processing machine 200, the operator first transports the workpiece to the workpiece loading position 201 outside the enclosed workpiece processing machine 200. Then, the operator manipulates the workpiece loading frame 100, causing the working end of the telescopic arm of its rotating telescopic arm assembly 2 to reach above the workpiece loading position 201 by swinging and extending. Figure 5 As shown, the end working mechanism 33 of the execution component 3 is lowered to load the workpiece to be processed onto it. Then, the workpiece loading frame 100 is continued to be manipulated so that the working end of the telescopic arm of the rotating telescopic arm assembly 2 reaches above the workpiece loading position 202 within the enclosed workpiece processing machine 200 through appropriate swinging and extension, as shown. Figure 6 As shown. Before or during this process, if necessary, the end effector 33 of the actuator 3 can be raised to prevent itself or the workpiece to be processed from colliding with other equipment or components within the encloseable workpiece processing machine 200. Next, the end effector 33 of the actuator 3 can be appropriately raised or lowered, and the end effector 33 can release the workpiece to be processed into the workpiece loading position 202. Then, other relevant components within the encloseable workpiece processing machine 200 can be manipulated to complete the clamping of the workpiece in the workpiece loading position 202. Then, before the processing operation begins, the workpiece loading rack 100 is manipulated to return the telescopic arm of its rotating telescopic arm assembly 2 to the retracted position and place it outside the operating space 203 of the processing operation equipment 210, as shown. Figure 7As shown, this is to avoid interference with the machining equipment 210 during operation, which could damage the equipment or affect the machining quality. After machining is completed, the workpiece can be unloaded from the enclosed workpiece machining machine 200 by following the reverse steps of the above operation.

[0068] Although specific embodiments of the present invention are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of the present invention. Various substitutions, alterations, and modifications may be conceived without departing from the spirit and scope of the present invention.
