Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material transportation tooling, in particular to a workpiece transfer device and a transfer method. BACKGROUND

[0002] For general machine processing equipment, the processing stations of the equipment exist independently. Taking a polishing processing station as an example, a polishing table is fixedly arranged at the processing station and can rotate around its own axis. A workpiece is fixed on the polishing table. A polishing robot is arranged beside the polishing table. The polishing table rotates and cooperates with the polishing robot to polish the workpiece. Since the installation positions of the polishing table and the polishing robot are fixed, the relative position accuracy of the two can be ensured, which can improve the processing accuracy of the workpiece. Compared with the way that the polishing robot surrounds the workpiece for 360° polishing, the equipment cost of the device provided with the rotatable polishing table is lower.

[0003] Before the workpiece is processed, the workpiece needs to be transferred from a feeding position to a processing station. At present, most of the workpiece transfer methods are manual transfer or single mechanical equipment transfer. When the workpiece is too heavy, the worker needs to use a lifting tool to transfer it. This method has low transfer efficiency and is complicated to operate. Moreover, there is a risk that the workpiece will fall or collide with the equipment during lifting, causing damage to the equipment. Therefore, it is a trend to transfer the workpiece by mechanical equipment, which has higher transfer efficiency and safety performance.

[0004] However, when a single mechanical equipment is used to transfer the workpiece, the transfer equipment needs to wait for manual feeding first. Then, the transfer equipment transfers the workpiece to the processing equipment for processing. During the processing, the workpiece is fixed by the mechanism of the processing station. After the processing is completed, the transfer equipment is reset, and the finished workpiece is unloaded. The next workpiece to be processed is installed on the transfer equipment. During the unloading of the finished workpiece and the installation of the next workpiece to be processed, the processing equipment needs to wait for feeding, which makes the waiting time for feeding longer and reduces the production efficiency.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0064] Referring to Figures 1 to 3 The present application provides a workpiece transfer device, which comprises a slide rail 1, a first sliding table 2 and a second sliding table 3 arranged on the slide rail 1, a rotary table machining module 4, a pair of tooling plates 6 and a pair of lifting mechanisms 5; the first sliding table 2 and the second sliding table 3 are arranged on the two sides of the rotary table machining module 4 correspondingly, and are connected with the slide rail 1 in transverse sliding mode; the pair of tooling plates 6 are arranged on the first sliding table 2 and the second sliding table 3 correspondingly, and the first sliding table 2, the second sliding table 3, the rotary table machining module 4 and the lifting mechanisms 5 are connected with the tooling plates 6 in vertical detachable mode; the pair of lifting mechanisms 5 are arranged on the two sides of the rotary table machining module 4 correspondingly in longitudinal mode; the lifting mechanisms 5 can be lifted in vertical mode; wherein the first sliding table 2 and the second sliding table 3 can be moved to the upper side of the rotary table machining module 4; the longitudinal size of the first sliding table 2 and the second sliding table 3 is not greater than the longitudinal distance of the pair of lifting mechanisms 5 after lifting, so that the lifting mechanisms 5 can lift the tooling plates 6 to separate from the first sliding table 2 or the second sliding table 3.

[0065] Figure 1 The mark X in the above formula is transverse, and the mark Z is vertical. Figure 2The mark Y in the figure is the longitudinal direction. The transverse direction is the sliding direction of the slide rail 1; the longitudinal direction is the direction perpendicular to the transverse direction in the horizontal plane; and the vertical direction is the height direction, which is also the lifting direction of the lifting mechanism 5. The lifting mechanism 5 can be driven by an electric push rod, a pneumatic cylinder or a hydraulic cylinder. The first sliding table 2 or the second sliding table 3 transports the workpiece to the rotary table machining module 4 for machining, and transports the machined workpiece to the original position for unloading, and then installs the next workpiece to be machined. The rotary table machining module 4 fixes the workpiece and cooperates with the external machining equipment to machine the workpiece.

[0066] The first sliding table 2 and the second sliding table 3 are used for feeding and unloading the workpiece. The first sliding table 2 feeds the first workpiece, and after the feeding is completed, the first sliding table 2 moves horizontally to above the rotary table machining module 4 with the first workpiece; the lifting mechanism 5 lifts the first workpiece to separate the first workpiece from the first sliding table 2, and the first sliding table 2 immediately moves away from above the rotary table machining module 4 in the reset direction to wait for the first workpiece to complete machining; the lifting mechanism 5 resets to directly place the first workpiece on the rotary table machining module 4, and the rotary table machining module 4 cooperates with the external machining mechanism (such as a polishing mechanism) to machine the first workpiece; during the above period, the second sliding table 3 feeds the second workpiece and moves to the right side of the rotary table machining module 4 to wait; after the first workpiece completes machining, the lifting mechanism 5 lifts the first workpiece to separate the first workpiece from the rotary table machining module 4, and the first sliding table 2 moves to above the rotary table machining module 4 and below the lifted first workpiece again, the lifting mechanism 5 resets, the first workpiece is alternately placed on the first sliding table 2, and the first sliding table 2 resets and unloads the first workpiece; during the resetting process of the first sliding table 2 with the machined first workpiece, the second sliding table 3, the rotary table machining module 4 and the pair of lifting mechanisms 5 cooperate to alternately place the second workpiece on the rotary table machining module 4 for machining. The feeding, machining and unloading processes of the second workpiece are consistent with those of the first workpiece, and will not be described again. The subsequent workpieces are processed according to the above steps in a cycle.

[0067] The workpiece transfer device uses double sliding tables to transfer the workpiece, and the feeding and machining are performed simultaneously. While the first workpiece is being machined, the second workpiece can be fed and moved to the right side of the rotary table machining module 4 to wait for machining at the same time. By using the staggered arrangement in space, the feeding time and the machining time are basically coincided, which greatly reduces the waiting time of the rotary table machining module 4, i.e. the machining equipment, for feeding, improves the overall machining rhythm and the utilization rate of the equipment.

[0068] A pair of lifting mechanisms 5 are correspondingly arranged on the two sides of the rotary table machining module 4 in a one-to-one correspondence in the longitudinal direction, and the longitudinal dimensions of the first sliding table 2 and the second sliding table 3 are both not greater than the longitudinal distance after the lifting of the pair of lifting mechanisms 5, so that the pair of lifting mechanisms 5 can lift the material after the first sliding table 2 or the second sliding table 3 moves above the rotary table machining module 4. Similarly, the material can also be taken from the rotary table machining module 4 and unloaded to the first sliding table 2 or the second sliding table 3. Finally, the alternating loading and unloading between the tooling plate 6, the sliding table, the lifting mechanism 5 and the rotary table machining module 4 is realized, and the tooling plate 6 on the first sliding table 2 can be immediately loaded after unloading, without waiting for the next feeding of the first sliding table 2, greatly shortening the waiting time of the rotary table machining module 4 for loading, and improving the production efficiency.

[0069] In the embodiment, the tooling plate 6 is used to fix the workpiece, and the tooling plate 6 and the workpiece are transported as a whole, and the workpiece does not directly contact the workpiece transporting device, thereby effectively protecting the workpiece. The longitudinal dimension of the tooling plate 6 is greater than the longitudinal dimension of the first sliding table 2, so that the lifting mechanism 5 can abut the part of the tooling plate 6 extending out of the first sliding table 2 in the longitudinal direction, thereby avoiding the first sliding table 2, the second sliding table 3 and the rotary table machining module 4, and realizing the separation of the tooling plate 6 and the sliding table (or the rotary table machining module 4).

[0070] Further, the top of the first sliding table 2, the second sliding table 3 and the lifting mechanism 5 is provided with a soft connecting piece, and the bottom of the tooling plate 6 abuts against the soft connecting piece. Specifically, the bottom of the tooling plate 6 can abut against the soft connecting piece of the first sliding table 2, the second sliding table 3 or the lifting mechanism 5, and the tooling plate 6 can obtain frictional resistance in the transverse and longitudinal directions through its own gravity, so that the corresponding mechanism can drive the tooling plate 6 to move, and the abutting connection mode facilitates the taking and placing of the workpiece, and improves the transportation efficiency of the tooling plate 6 between the corresponding mechanisms. The soft connecting piece is an elastic member capable of bearing a certain deformation, which can buffer the collision force between the tooling plate 6 and the corresponding mechanism, and on the other hand, can improve the frictional resistance of the workpiece and the stability of the workpiece transportation process.

[0071] Referring to Figure 4The soft connecting piece comprises a first supporting wheel 21 and a second supporting wheel 22 arranged in a group; the first supporting wheel 21 and the second supporting wheel 22 are arranged on the first sliding table 2, the second sliding table 3 or the lifting mechanism 5 correspondingly; the axis of the first supporting wheel 21 is perpendicular to the transverse direction; and the axis of the second supporting wheel 22 is perpendicular to the longitudinal direction. Specifically, a plurality of groups of supporting wheels can be arranged on the first sliding table 2, the second sliding table 3 or the lifting mechanism 5, and the supporting wheels can provide a supporting surface for the tool plate 6 after elastic deformation, thereby meeting the supporting function and being easy to separate from the workpiece. The axial perpendicular arrangement of the first supporting wheel 21 and the second supporting wheel 22 enables the first supporting wheel 21 and the second supporting wheel 22 to combine to form a horizontal limiting system, thereby avoiding the tool plate 6 from moving on the sliding table and improving the stability of the tool plate 6 during transfer. For some tool plates 6 (or workpieces) with a groove or a stand designed at the bottom, the soft connecting piece is designed as a wheel body structure, so that the supporting wheels can be clamped in the groove, thereby further improving the horizontal limiting strength of the tool plate 6. Secondly, since the wheel body is sleeved on the rotating shaft and has an inner supporting structure, the supporting nodes formed by the plurality of supporting wheels can stably support the tool plate 6, so that the top surface of the tool plate 6 is parallel to the horizontal surface, thereby ensuring the positioning accuracy of the workpiece.

[0072] Referring to Figure 5 , the lifting mechanism 5 comprises a lifting table 51, a lifting driver 52 and a guide rail 53; the lifting driver 52 and the guide rail 53 are installed on the side plates of the sliding rail 1 correspondingly; the lifting table 51 is connected with the push rod of the lifting driver 52; and the lifting table 51 is slidingly connected with the guide rail 53 in the vertical direction. The lifting driver 52 can be selected from an electric push rod, an air cylinder or a hydraulic cylinder. A group of supporting wheels is arranged on both sides of the top end of the lifting table 51, thereby realizing stable support of the tool plate 6.

[0073] As shown in Figure 6 , the soft connecting piece is a protruding piece 23; the top of the first sliding table 2 and the top of the second sliding table 3 are both provided with the protruding piece 23; and the protruding piece 23 is in surface abutment with the bottom surface of the tool plate 6. The protruding piece 23 and the supporting wheel can be independently arranged or combined. In this embodiment, the protruding piece 23 is an elastic protruding block, which can be a rubber protruding block, and has a buffering function and a large friction coefficient, thereby further improving the limiting strength of the soft connecting piece to the workpiece. Figure 7 and Figure 8 , the first supporting wheel 21, the second supporting wheel 22 and the protruding piece 23 are in abutment with the bottom of the tool plate 6 correspondingly, and utilize frictional resistance to realize horizontal limiting and are easy to separate in the vertical direction; when the first supporting wheel 21, the second supporting wheel 22 and the protruding piece 23 are used in combination, the supporting wheel improves the supporting strength, and the protruding piece 23 improves the frictional resistance. Through the support and limiting of the workpiece by the soft connecting piece, the relative independence between the tool plate 6 and the first sliding table 2, the second sliding table 3 and the lifting mechanism 5 is ensured, thereby facilitating the transfer of the tool plate 6 between the mechanisms.

[0074] Further, the bottom of the first sliding table 2 and the second sliding table 3 is provided with a plurality of walking wheels 24; the walking wheels 24 are movably connected with the slide rail 1 in the transverse direction. The first sliding table 2 and the second sliding table 3 are configured as a vehicle body, which reduces the frictional resistance between the sliding table and the slide rail 1, the sliding table slides more smoothly, and the reliability of the soft connecting piece is improved. As shown in Figure 8 The profile of the walking wheel 24 is recessed inwardly and is fitted with the slide rail 1, so that the slide rail 1 can limit the walking wheel 24 in the longitudinal direction, effectively avoiding the sliding table from coming out of the slide rail 1.

[0075] Referring to Figure 9 , the rotary table machining module 4 includes a rotary table 41 and a clamping mechanism 42 and a support column 43 arranged on the rotary table 41; the rotary table 41 is arranged on the inner side of the slide rail 1; the rotary table 41 can rotate around the vertical direction; the clamping mechanism 42 is arranged on the rotary table 41 and can be connected with the bottom of the tooling plate 6 to limit the tooling plate 6 in the transverse and longitudinal directions; the support column 43 can be connected with the bottom of the tooling plate 6. Specifically, the support column 43 is inserted into or clamped with the positioning hole or clamping groove arranged on the bottom of the tooling plate 6, and then the tooling plate 6 is horizontally limited by the clamping mechanism 42, effectively avoiding the tooling plate 6 from moving due to external forces during machining, and ensuring the machining accuracy. The rotary table 41 can rotate 360° around the vertical direction, thereby driving the tooling plate 6 to rotate, cooperating with the external machining equipment to machine the workpiece on the tooling plate 6, and the 360° rotation can ensure the completion of the machining of the workpiece.

[0076] Optionally, a pair of clamping mechanisms 42 are arranged on the two sides of the rotary table 41 correspondingly. The combination of the pair of clamping mechanisms 42 can improve the stability of the workpiece during machining and avoid the tooling plate 6 from moving on the rotary table 41. The specific number of the clamping mechanisms 42 is determined according to the required limiting strength during actual machining.

[0077] As shown in Figures 10 to 12 , the bottom of the tooling plate 6 is provided with an L-shaped limiting block 61; the clamping mechanism 42 includes a corner oil cylinder 421 and a clamping plate 422; the corner oil cylinder 421 is arranged on the rotary table 41; the rotating shaft of the corner oil cylinder 421 is connected with the clamping plate 422 and can drive the clamping plate 422 to ascend and descend in the vertical direction and rotate in the horizontal plane, so that the clamping plate 422 is clamped with the L-shaped limiting block 61. Specifically, the corner oil cylinder 421 is an existing corner oil cylinder, which can not only drive the rotating shaft to extend and retract, but also drive the rotating shaft to rotate, thereby ensuring that the tooling plate 6 does not collide with the clamping plate 422 during the process of lowering the tooling plate 6 onto the rotary table 41, and can clamp the L-shaped limiting block 61 after the tooling plate 6 is lowered onto the rotary table 41. The clamping plate 422 is clamped on the inner side of the corner of the L-shaped limiting block 61, thereby limiting the tooling plate 6. Optionally, a pair of clamping mechanisms 42 are mirror arranged on the rotary table 41, which can be combined to clamp the tooling plate 6.

[0078] Further, the tooling plate 6 further comprises a plate body 64, and a first block 62 and a second block 63 arranged on the bottom of the plate body 64; the second block 63 is arranged between the first block 62 and the L-shaped limiting block 61; the first block 62 can abut against the lifting mechanism 5; and the second block 63 can abut against the first sliding table 2 or the second sliding table 3. Specifically, the number and size of the first block 62 and the second block 63 are matched with the number and size of the corresponding soft connecting pieces, and the first block 62 and the second block 63 can be selected as rubber blocks to improve the frictional resistance with the soft connecting pieces. By reasonably arranging the mounting positions of the first block 62, the second block 63 and the L-shaped limiting block 61 on the bottom of the plate body 64, the tooling plate 6 can adapt to the transfer operation of the sliding table, the lifting mechanism 5 and the clamping mechanism 42, and realize the automatic feeding and discharging of the tooling plate 6.

[0079] In addition, the first sliding table 2 and the second sliding table 3 are both provided with a hook hand 25; the top end of the hook hand 25 is connected with the first sliding table 2 or the second sliding table 3, and the bottom end abuts against the bottom of the slide rail 1; and the hook hand 25 can vertically limit the first sliding table 2 or the second sliding table 3. Specifically, the bottom end of the hook hand 25 is provided with a roller, which abuts against the bottom of the slide rail 1 and can move in the transverse direction. The hook hand 25 can limit the sliding table in the vertical direction, effectively avoiding the sliding table from being separated from the slide rail 1, and improving the reliability of the vehicle body in transferring the workpiece on the slide rail 1.

[0080] In addition, the present application also provides a transfer method of the workpiece transfer device, which is based on the above-mentioned workpiece transfer device and comprises the following steps:

[0081] A pair of tooling plates 6 are placed on the first sliding table 2 and the second sliding table 3 correspondingly; and a first workpiece and a second workpiece are placed and fixed on the tooling plates 6 of the first sliding table 2 and the second sliding table 3 correspondingly;

[0082] The first sliding table 2 moves on the slide rail 1 in the transverse direction to transport the tooling plate 6 to the top of the rotary table machining module 4; a pair of lifting mechanisms 5 correspondingly lift the two sides of the bottom of the tooling plate 6, that is, the first block 62, so that the tooling plate 6 is separated from the first sliding table 2; the first sliding table 2 moves to the first material waiting station or returns to the original position; the lifting mechanism 5 returns to the original position, so that the tooling plate 6 moves to the rotary table machining module 4, and the bottom end of the tooling plate 6 is inserted into the plurality of support columns 43; and the clamping mechanism 42 clamps the tooling plate 6;

[0083] The rotary table 41 cooperates with the external processing equipment to process the first workpiece; after the processing of the first workpiece is completed, the pair of lifting mechanisms 5 correspondingly lifts the tooling plate 6 one by one, so that the tooling plate 6 is separated from the rotary table processing module 4; the first sliding table 2 moves from the first standby position or the first original position (the original position is the reset position) to the upper side of the rotary table processing module 4, and the lifting mechanism 5 is reset, so that the tooling plate 6 is moved to the first sliding table 2;

[0084] The first sliding table 2 is reset and the first workpiece is unloaded; at the same time, the second sliding table 3 located in the second standby position or the second original position moves to the upper side of the rotary table processing module 4 to perform loading, and the processing and unloading of the second workpiece and subsequent workpieces are completed according to the above steps.

[0085] The workpiece transfer device adopts double stations to work, and the workpiece is transferred through the pair of lifting mechanisms 5, so that the workpiece is alternated on the rotary table processing module 4 and the sliding table, and the limitation on the processing side sliding table is ingeniously eliminated, that is, the processing side sliding table does not need to wait in the standby position beside the rotary table processing module 4 (wait for the workpiece processed on the rotary table processing module 4 to be carried), and can move to the loading position to load the next workpiece while the workpiece is being processed, thereby improving the flexibility of the processing side sliding table. While one side of the workpiece transfer device is being processed, the other side is loaded at the same time, which reduces the loading and unloading time of the workpiece and the waiting time of the rotary table processing module 4 for loading, thereby improving the production efficiency.

[0086] In the actual processing process, the first standby position is arranged between the rotary table processing module 4 and the first sliding table 2, and the second standby position is arranged between the rotary table processing module 4 and the second sliding table 3. When the first workpiece is processed, the first sliding table 2 waits in the first standby position, and the second sliding table 3 waits in the second standby position. The horizontal moving path of the standby position to the rotary table processing module 4 is relatively short, which further reduces the waiting time of the rotary table processing module 4 for loading.
