Description

Technical Field

[0001] This application belongs to the field of machining equipment technology, and in particular relates to a wire drawing device for continuously machining multiple machining surfaces on the same workpiece. Background Technology

[0002] With continuous social progress and rapid technological development, the market demand for many products is increasing, and the requirements are also becoming more stringent. Therefore, it is necessary to both ensure product quality and improve production efficiency in order to meet market demands.

[0003] Many metal products require surface brushing after machining or 3D printing to create a brushed effect and improve product quality. Current brushing equipment can only process one surface of the workpiece. When switching the processing area, manual intervention is needed, such as rotating the workpiece to change the processing area. Alternatively, a robotic arm can be used to transfer the workpiece to the next brushing device, rotating it during the extraction, transfer, and placement process to switch the processing area.

[0004] As can be seen, both of the above operation methods require reclamping the workpiece. Each time the workpiece is switched to be processed, multiple steps of disassembly, transfer, rotation, and clamping are required. Since a single workpiece has multiple processing parts, each requiring this series of operations, the entire process of switching processing parts is very cumbersome, affecting processing efficiency. Moreover, after each reclamping, multiple calibration operations are needed to ensure the accuracy of the clamping position, thus ensuring processing precision and resulting in low production efficiency. Summary of the Invention

[0005] The purpose of this application is to provide a wire drawing device to solve the technical problem that the prior art requires transfer and reclamping when adjusting the workpiece to be processed, which affects the processing accuracy.

[0006] To achieve the above objectives, the technical solution adopted in this application is: to provide a wire drawing device, comprising:

[0007] The conveyor belt is provided with multiple loading platforms, which are spaced apart on the conveyor belt; each loading platform has a mounting groove for mounting workpieces, and the mounting groove includes an upper opening and an operating opening for exposing the end of the workpiece, the upper opening being used to expose the part of the workpiece to be processed.

[0008] A wire drawing mechanism includes a pusher, a roller, and an abrasive belt driven by the roller. The pusher is used to push at least a portion of the abrasive belt onto the workpiece for wire drawing. The wire drawing equipment has multiple wire drawing mechanisms on the conveyor belt according to the number of parts to be processed on the workpiece.

[0009] A flipping mechanism is provided between two adjacent wire drawing mechanisms. The flipping mechanism includes a lifting device and a rotating device provided on the lifting device. The rotating device is provided with a first suction cup for picking up the workpiece. The flipping mechanism is used to lift the workpiece from the loading table and rotate it, thereby switching the processed part of the workpiece and placing it back on the loading table.

[0010] The beneficial effects of the wire drawing equipment provided in this application are as follows: Compared with the prior art, the wire drawing equipment of this application has a corresponding number of wire drawing mechanisms according to the number of processed parts on the workpiece, and a flipping mechanism is set between two adjacent wire drawing mechanisms. As the conveyor belt operates, the loading platforms carrying workpieces on the conveyor belt are sequentially transported to each wire drawing mechanism, allowing the wire drawing mechanism to perform wire drawing processing on the processed parts of the workpiece. The flipping mechanism performs a switching operation on the processed parts of the workpiece on the loading platform between two adjacent wire drawing mechanisms, so that the subsequent wire drawing mechanism can process the workpiece with the switched processed parts, thereby realizing the sequential processing of multiple processed parts on the same workpiece. In this way, the workpiece does not need to be disassembled from the wire drawing equipment and transferred to another equipment for re-clamping, and the multiple processed parts on the workpiece can be automatically switched and processed, effectively saving the cumbersome operation of transferring from one equipment to another, thereby improving operating efficiency.

[0011] The structure of the flipping mechanism is improved. The lifting device includes a bracket, a support arm and a first driver mounted on the bracket. The support arm extends to the conveyor belt. The rotating device is mounted on the support arm. The first driver drives the support arm to carry the rotating device and move it up and down on the bracket, thereby realizing automatic lifting and placing of workpieces on the loading platform.

[0012] In one embodiment, the rotating device includes a drive base and a rotating head connected to each other. The rotating head is provided with the first suction cup. The drive base is disposed on the support arm and is provided with a drive motor. The drive motor drives the rotating head to rotate the workpiece, thereby switching the processed part on the workpiece. Under the drive of the above-mentioned lifting device, the workpiece is placed back on the loading table, automatically completing the disassembly of the workpiece, switching of the processed part and re-clamping.

[0013] In one embodiment, the output shaft of the drive motor, the rotating head, the first suction cup, and the mounting slot of the loading table are coaxially aligned. Therefore, after the workpiece rotates to switch the processing area, the lifting device drives the workpiece up and down, accurately placing it back into the mounting slot of the loading table. This effectively ensures the workpiece's positioning and improves the accuracy of workpiece reclamping.

[0014] An improvement is made to the structure of the wire drawing mechanism, which includes a second driver and three rollers. The abrasive belt is mounted on the three rollers, and a pushing device is disposed between the three rollers. One of the three rollers is a movable roller that can move along the height direction, and the movable roller is positioned at a higher height than the other two rollers. At least one of the other two rollers is drivenly connected to the second driver. Thus, the movable roller allows the abrasive belt to remain taut, thereby ensuring a good wire drawing effect on the workpiece.

[0015] In one embodiment, the wire drawing mechanism further includes a locking mechanism for unlocking the movable roller. The locking mechanism includes a support shaft and a support frame arranged vertically. The movable roller is sleeved on the support shaft and rotated by the sanding belt. A connecting rod and an elastic element are provided between the support shaft and the support frame. The connecting rod is connected to the support shaft, and the elastic element has an expansion force that drives the connecting rod to drive the support shaft, expanding the movable roller outward to tighten the sanding belt. The support frame also has a handle connected to the connecting rod's rotating shaft. The handle is used to drive the connecting rod to compress the elastic element, thereby releasing the outward expansion force on the movable roller. On one hand, the expansion force of the elastic element drives the movable roller outward, keeping the sanding belt taut and ensuring the wire drawing effect on the workpiece. On the other hand, operating the handle to compress the elastic element releases the tension of the sanding belt, allowing for belt replacement.

[0016] Another improvement to the wire drawing mechanism is made: the wire drawing mechanism includes a second driver and two rollers, with the abrasive belt mounted on the two rollers, and a pushing device disposed between the two rollers; the two rollers are positioned at the same height, and at least one of the two rollers is drively connected to the second driver. Thus, the wire drawing mechanism can adopt a horizontally arranged two-roller layout, which helps save space in the equipment.

[0017] The structure of the pushing device is improved, comprising a third driver and a pressing head. The third driver drives the pressing head to push at least a portion of the abrasive belt against the workpiece placed on the loading table. Thus, the pushing device effectively ensures that the abrasive belt remains firmly attached to the workpiece on the loading table, guaranteeing a smooth wire-drawing effect on the machined portion of the workpiece.

[0018] The structure of the wire drawing equipment is improved. The wire drawing equipment also includes a feeding conveyor belt and a discharging conveyor belt that are respectively arranged adjacent to both ends of the conveyor belt. The two ends of the conveyor belt are also provided with a loading mechanism and a unloading mechanism. The loading mechanism transfers the workpiece from the feeding conveyor belt to each of the loading platforms of the conveyor belt, and the unloading mechanism transfers the workpiece from each of the loading platforms to the discharging conveyor belt, thereby replacing manual labor to realize automatic loading and unloading of workpieces.

[0019] In one embodiment, the wire drawing equipment further includes a robotic arm disposed between an extension end of the infeed conveyor belt and an extension end of the discharge conveyor belt. Thus, both loading and unloading operations can be performed using a single robotic arm. Attached Figure Description

[0044] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0045] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0046] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] For a workpiece with multiple machining areas, as an example, such as Figure 1 As shown, the workpiece 100 is a rectangular body. One end of the workpiece 100 has an opening N1, and the other end is a flat surface, which can be used as an operating end N2 for being picked up by a suction cup. The outer periphery of the workpiece 100 has four flat surfaces. One of these four surfaces has a pre-machined structure M1, while the other three serve as the machined parts M2, all of which require wire drawing. Therefore, during the machining process, three flat surfaces on the surface of the workpiece 100 need to be machined sequentially.

[0049] The wire drawing equipment provided in this application embodiment can automatically and sequentially complete the wire drawing process of the three planes of the workpiece 100, effectively replacing manual operation. When switching the processing part of the workpiece 100, it can effectively ensure the accuracy of the processing part after the workpiece 100 is reclamped, thereby solving the problem that when adjusting the processing part of the workpiece 100 on traditional wire drawing equipment, it is necessary to transfer and reclamp the workpiece 100, which affects the processing accuracy. It will now be described in detail.

[0050] Please see Figure 2 The wire drawing equipment includes at least a conveyor belt 1, and a plurality of wire drawing mechanisms 2 and a plurality of flipping mechanisms 3 disposed on the conveyor belt 1.

[0051] The conveyor belt 1 is provided with multiple loading platforms 11 for placing workpieces 100 respectively. The multiple loading platforms 11 are arranged at intervals on the conveyor belt 1. As the conveyor belt 1 operates, the multiple loading platforms 11, each carrying a workpiece 100, pass through each wire drawing mechanism 2 and each flipping mechanism 3 in sequence.

[0052] Please see Figure 3 The loading platform 11 has a mounting groove 111 for mounting the workpiece 100. The mounting groove 111 includes at least an upper opening 112 and an operating port 113. The operating end of the workpiece 100 protrudes from the operating port 113, and the upper opening 112 is used to expose the part of the workpiece 100 to be processed. In this embodiment, the workpiece 100 is placed in the mounting groove 111 of the loading platform 11 so that one of the three surfaces of the workpiece 100 to be processed is exposed in the upper opening 112, so that it can be drawn by the wire drawing mechanism 2 when passing under it.

[0053] Please refer to the following: Figure 4 and Figure 5 The wire drawing mechanism 2 includes at least a pushing device 21, a roller 22, and an abrasive belt 23. The abrasive belt 23 is mounted on the roller 22, and the roller 22 drives the abrasive belt 23 to rotate. The pushing device 21 is used to push at least a portion of the abrasive belt 23 onto the workpiece 100 to draw the workpiece 100 exposed on the upper opening 112 of the loading table 11.

[0054] The wire drawing equipment has multiple wire drawing mechanisms 2 arranged on the conveyor belt 1 according to the number of parts to be processed on the workpiece 100. In this embodiment, as mentioned above, the workpiece 100 has three surfaces to be processed. Therefore, the wire drawing equipment of this embodiment has three sets of wire drawing mechanisms 2 according to the number of parts to be processed on the workpiece 100. These three sets of wire drawing mechanisms 2 are arranged in an orderly manner on the conveyor belt 1 along the length direction of the conveyor belt 1 via a back plate. As the conveyor belt 1 operates, each loading platform 11 on the conveyor belt 1 carries the workpiece 100 and passes under the three sets of wire drawing mechanisms 2 in sequence, allowing each wire drawing mechanism 2 to perform wire drawing processing on the parts of the workpiece 100 on each loading platform 11.

[0055] Please refer to the following: Figure 4 , Figure 5 and Figure 6The flipping mechanism 3 is disposed between two adjacent wire drawing mechanisms 2. This can be understood as follows: since there are three planes to be processed on the workpiece 100, at least two flipping operations are required to switch the processed parts. Therefore, in this embodiment, the wire drawing device of this application embodiment is provided with two sets of flipping mechanisms 3, each set of flipping mechanisms 3 being disposed between two adjacent wire drawing mechanisms 2.

[0056] Each flipping mechanism 3 includes a lifting device 31 and a rotating device 32, with the rotating device 32 mounted on the lifting device 31. The rotating device 32 is equipped with a first suction cup 321 for picking up the workpiece 100. Through the structural combination of the lifting device 31 and the rotating device 32, the flipping mechanism 3 lifts the workpiece 100 from the loading table 11 and rotates it, thereby switching the processed part of the workpiece 100 and placing it back on the loading table 11.

[0057] When the flipping mechanism 3 operates on the workpiece 100 via the first suction cup 321, the first suction cup 321 picks up the operating end of the workpiece 100 protruding from the operating port 113 of the loading table 11 and lifts the workpiece 100 from the loading table 11; then, the workpiece 100 is rotated to switch the parts to be processed on the workpiece 100, such as adjusting the plane to be processed on the outer periphery of the workpiece 100; finally, the workpiece 100 is placed back on the mounting slot 111 of the loading table 11. It can be seen that as the conveyor belt 1 operates, the loading table 11 carries the workpiece 100 to the next wire drawing mechanism 2 for wire drawing, and in this way, the wire drawing process on multiple parts of the workpiece 100 is automatically completed.

[0058] Compared with the prior art, the wire drawing equipment provided in this application embodiment has a corresponding number of wire drawing mechanisms 2 according to the number of processed parts on the workpiece 100, and a flipping mechanism 3 is set between two adjacent wire drawing mechanisms 2. As the conveyor belt 1 operates, the loading platforms 11 carrying workpieces 100 on the conveyor belt 1 are sequentially transported to each wire drawing mechanism 2, allowing the wire drawing mechanism 2 to perform wire drawing processing on the processed parts of the workpiece 100. The flipping mechanism 3 performs a switching operation on the processed parts of the workpiece 100 on the loading platform 11 between two adjacent wire drawing mechanisms 2, so that the subsequent wire drawing mechanism 2 can process the workpiece 100 with the switched processed parts, thereby realizing the sequential processing of multiple processed parts on the same workpiece 100.

[0059] In this way, the workpiece 100 does not need to be disassembled from the wire drawing equipment and transferred to another equipment for reclamping. Multiple processing parts on the workpiece 100 can be automatically switched and processed, effectively saving the cumbersome operation of transferring from one equipment to another, thereby improving operating efficiency.

[0060] In the process of switching the workpiece 100's processing parts, the flipping mechanism 3 lifts the workpiece 100 from the loading table 11 using the first suction cup 321 and rotates it to switch the processing parts on the workpiece 100 before placing it back onto the loading table 11. At this time, the workpiece 100 is quickly positioned using the mounting slot 111 on the loading table 11, effectively ensuring the processing accuracy of the processing parts on the workpiece 100 and thus improving the yield rate.

[0061] For the specific structure of the flipping mechanism 3, please refer to one embodiment of this application. Figure 6 In the wire drawing equipment provided in this application embodiment, the lifting device 31 in each flipping mechanism 3 includes a bracket 311, a support arm 312 and a first driver 313 disposed on the bracket 311. The bracket 311 is disposed close to the conveyor belt 1 so that the support arm 312 can extend onto the conveyor belt 1.

[0062] The rotating device 32 is mounted on the support arm 312, so that the first suction cup 321 mounted on the rotating device 32 can be positioned on the conveyor belt 1, and the first suction cup 321 can pick up the workpiece 100 from the loading table 11.

[0063] The first actuator 313 can preferably be a linear cylinder. The first actuator 313 drives the support arm 312, which carries the rotating device 32, to move up and down on the bracket 311, thereby realizing the automatic lifting and placing of the workpiece 100 on the loading platform 11. At the same time, during the lifting action, the support arm 312 can also avoid the loading platform 11, so that each loading platform 11 on the conveyor belt 1 can pass smoothly under the flipping mechanism 3.

[0064] For the specific structure of the rotating device 32, please refer to one embodiment of this application. Figure 6 The rotating device 32 includes a drive base 322 and a rotating head 323 connected to each other, and the rotating head 323 is provided with a first suction cup 321.

[0065] The drive base 322 is mounted on the support arm 312. The drive base 322 contains a drive motor, which can preferably be a stepper motor. The output shaft of the drive motor is connected to the rotating head 323, which drives the rotating head 323 to rotate the first suction cup 321 to rotate the workpiece 100, thereby switching the processing part on the workpiece 100. Under the drive of the lifting device 31, the workpiece 100 is placed back on the loading table 11, automatically completing the disassembly, switching of processing parts and re-clamping of the workpiece 100.

[0066] Preferably, such as Figure 6As shown, the output shaft of the drive motor, the rotating head 323, the first suction cup 321, and the mounting slot 111 of the loading table 11 are coaxially aligned. Therefore, after the workpiece 100 rotates to switch the processing area, the lifting device 31 drives the workpiece 100 up and down, accurately placing it back into the mounting slot 111 of the loading table 11. This effectively ensures the positioning of the workpiece 100 and improves the accuracy of re-clamping it.

[0067] For the structure on the loading platform 11, please refer to one embodiment of this application. Figure 3 and Figure 7 The width H1 of the mounting groove 111 on each loading platform 11 is preferably greater than the width H2 of the workpiece 100, so that the inner wall of the mounting groove 111 and the outer periphery of the workpiece 100 can have a certain margin gap, thereby making it easier for the workpiece 100 to be loaded into the mounting groove 111 of the loading platform 11, thereby improving the operating efficiency.

[0068] In another embodiment of this application (not shown in the figures), each loading platform 11 also has a chamfer around the outer periphery of the upper opening 112, so that a guide slope gradually inclines into the mounting groove 111 is formed on the outer periphery of the upper opening 112. This facilitates the easy loading of the workpiece 100 into the mounting groove 111 of the loading platform 11, further improving the assembly efficiency of the workpiece 100.

[0069] Regarding the structure on conveyor belt 1, please refer to one embodiment of this application. Figure 8 The conveyor belt 1 includes a chain 12 and a roller assembly 13 for driving the chain 12. The aforementioned plurality of loading platforms 11 are spaced apart on the chain 12. At least one roller in the roller assembly 13 is connected to an external drive device (not shown) so that the roller assembly 13 can drive the chain 12.

[0070] Preferably, such as Figure 8 As shown, the chain 12 is provided with a plurality of mounting parts 121 for mounting the material carrier 11. These mounting parts 121 can be mounting bases or other structures such as sockets that allow the material carrier 11 to be detachably fixed thereon, and no specific limitation is made here. These mounting parts 121 are arranged in an orderly manner on the chain 12 along the length direction of the chain 12.

[0071] Each loading platform 11 has a fixing part 114 at its bottom for fixing to the chain 12, and the fixing part 114 is used to selectively install on the mounting part 121 of the chain 12 to achieve quick assembly and disassembly.

[0072] In this way, each loading platform 11 can be selectively installed on each mounting part 121 of the chain 12 according to actual application requirements, which is conducive to adjusting the spacing of each loading platform 11 on the conveyor belt 1, thereby improving the processing adaptability of each processing part on the workpiece 100.

[0073] For the structure of the wire drawing mechanism 2, please refer to one embodiment of this application. Figure 9 and Figure 10 Each wire drawing mechanism 2 in the wire drawing equipment includes a second driver 24 and three rollers 22. The sanding belt 23 is mounted on the three rollers 22, and the pushing device 21 is disposed between the three rollers 22.

[0074] In this embodiment, one of the three rollers 22 is a movable roller 221 that can move along the height direction, and the movable roller 221 is set at a higher height than the other two rollers 22. The other two rollers 22 can preferably be arranged horizontally aligned, so that the three rollers 22 form an equilateral triangle layout, which is beneficial to improving the smoothness of the operation of the sanding belt 23.

[0075] As an example, for the height adjustment of the movable roller 221, a lifting mechanism (not shown in the figure) can be preferably set on the wire drawing mechanism 2. The movable roller 221 is connected to the output end of the lifting mechanism, and under the drive of the lifting mechanism, the movable roller 221 can move up and down, thereby finely adjusting the height position of the movable roller 221.

[0076] Therefore, the tension of the sanding belt 23 can be adjusted by using the movable roller 221, so that the tension of the sanding belt 23 on the roller 22 can be adjusted according to the consumption of the sanding belt 23, effectively improving the utilization rate of the sanding belt 23, and thus ensuring the wire drawing effect on the workpiece 100.

[0077] like Figure 9 As shown, at least one of the remaining two rollers 22 is drive-connected to the second driver 24. Regarding the drive connection structure between the second driver 24 and the rollers 22, in this embodiment, as follows... Figure 1 As shown, the second driver 24 can preferably be a rotary motor, and the output end of the second driver 24 is connected to the roller 22 via a transmission belt 241. In other embodiments (not shown), the output end of the second driver 24 and the roller 22 can also be connected by a gear set to achieve the same transmission effect.

[0078] Preferably, in one embodiment of this application, please refer to Figure 10 The wire drawing mechanism 2 also includes a locking mechanism for unlocking the movable roller 221. The locking mechanism includes a support shaft 25 and a support frame 26 arranged vertically. The support shaft 25 extends laterally between the three rollers 22. The movable roller 221 is sleeved on the support shaft 25 and is driven to rotate by the sanding belt 23.

[0079] A connecting rod 27 and an elastic element 28 are provided between the support shaft 25 and the support frame 26. The connecting rod 27 is connected to the support shaft 25. The elastic element 28 can preferably be a spring so that the elastic element 28 has an elastic outward expansion force, thereby driving the connecting rod 27 to drive the support shaft 25 to expand the movable roller 221 outward, so that the sanding belt 23 can be tightened.

[0080] The support frame 26 is also equipped with a handle 29, which is connected to the connecting rod 27 via a pivot. The handle 29 is used to drive the connecting rod 27 to compress the elastic element 28, thereby releasing the outward expansion force on the movable roller 221 and releasing the tension on the sanding belt 23.

[0081] Thus, on the one hand, the expansion force of the elastic element 28 drives the movable roller 221 to expand outward, thereby keeping the sanding belt 23 taut and ensuring the wire-drawing effect on the workpiece 100. On the other hand, the handle 29 is pulled down to compress the elastic element 28, so that the movable roller 221 releases the tension on the sanding belt 23, making it easier to replace the sanding belt 23.

[0082] In another embodiment of this application (not shown in the figures), each wire drawing mechanism 2 on the wire drawing equipment includes a second driver 24 and two rollers 22, with an abrasive belt 23 mounted on the two rollers 22. The second driver 24 can preferably be a rotary motor, and at least one of the two rollers 22 is drive-connected to the second driver 24. The drive connection between the second driver 24 and the rollers 22 can also be achieved using the aforementioned drive belt 241 or a gear set; no specific limitation is made here.

[0083] In this embodiment, the two rollers 22 are both set at the same height and spaced apart, so that the pushing device 21 can be set between the two rollers 22.

[0084] Therefore, the wire drawing mechanism 2 adopts a layout of two horizontally arranged rollers 22, which helps to save space occupied by the equipment.

[0085] For the specific structure of the pushing device 21, please refer to one embodiment of this application. Figure 10 The pushing device 21 includes a third driver 211 and a pressing head 212. The third driver 211 can preferably be a linear cylinder. The output end of the third driver 211 is connected to the pressing head 212 and drives the pressing head 212 to push at least a portion of the sand belt 23 onto the workpiece 100 placed on the loading table 11.

[0086] In this way, the pushing device 21 pushes the sanding belt 23 to keep it in close contact with the workpiece 100 on the loading table 11, effectively ensuring the wire drawing effect on the processed part of the workpiece 100.
