Description

Technical Field

[0001] This invention belongs to the field of automated equipment, and in particular relates to a processing equipment for a circular frame of a welding wire shaft. Background Technology

[0002] After the welding wire is processed, workers will wind the welding wire around the outside of the welding wire spool according to actual needs, so as to facilitate the packaging and transportation of the welding wire. Under normal circumstances, there should be a circular frame at both ends of the welding wire spool. When the welding wire is wound around the outside of the welding wire spool, the circular frame can axially limit the welding wire to prevent the wound welding wire from separating from the welding wire spool.

[0003] To reduce the overall weight of the welding wire spool, the circular frame of existing welding wire spools generally adopts a design such as... Figure 1 The structure shown is as follows. During processing, workers first need to evenly weld multiple strips onto the outer wall of the inner ring. Then, the inner ring with the welded strips is transferred to the inside of the outer ring, and the other end of the strips is welded to the inner wall of the outer ring to complete the production of a circular frame.

[0004] However, as welding wire production gradually increases, the amount of welding wire spools used also gradually increases, and correspondingly, the demand for circular frames will also rise significantly. Currently, there is a lack of specialized equipment for manufacturing circular frames, so workers can only perform the welding of the banners and inner and outer rings by hand, resulting in low processing efficiency and failing to meet the needs of large-scale welding wire production. Summary of the Invention

[0005] In view of this, the present invention aims to provide a circular frame processing device for welding wire spools, so as to improve the processing efficiency of circular frame welding wire spools.

[0006] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0007] A circular frame processing device for welding wire spools includes: a pickup unit, an inner ring feeding unit, a strip processing unit, and an outer ring processing unit, and a first station, a second station, and a third station arranged in a ring around the pickup unit.

[0008] The pickup unit includes a frame, a drive assembly, and a pickup assembly. The frame is vertically and flexibly mounted on the rotation shaft of the drive assembly, and the pickup assembly is mounted on the frame. The pickup assembly has a first working state and a second working state. When the pickup assembly is in the first working state, it remains relatively stationary with respect to the frame. When the pickup assembly is in the second working state, it can rotate relative to the frame. The rotation of the frame allows the pickup assembly to sequentially pass through a first workstation, a second workstation, and a third workstation. When the pickup assembly is aligned with any workstation, the lifting and lowering of the frame allows the pickup assembly to switch between the first and second working states.

[0009] The inner ring feeding unit is located inside the first station. The inner ring feeding unit includes a support plate and an inner ring feeding assembly. A pickup slot is provided on the support plate. The inner ring feeding assembly is used to feed inner ring material into the pickup slot.

[0010] The banner processing unit is located inside the second station. The banner processing unit includes a banner feeding assembly and a banner welding assembly. The banner welding assembly is provided with a storage tank. The banner feeding assembly is used to feed banner material into the storage tank. The banner welding assembly enables the banner material inside the storage tank to be welded with the inner ring material entering the second station to form a semi-finished product.

[0011] The outer ring processing unit is located inside the third station. The outer ring processing unit includes an outer ring feeding component, an indexing plate, and an outer ring welding component. The outer ring feeding component is used to feed the outer ring material to the indexing plate, and the outer ring welding component enables the outer ring material on the indexing plate to be welded to the semi-finished material entering the third station.

[0012] Furthermore, the picking component includes: a picking body, an elastic constraint ring, and multiple clamping claws. The elastic constraint ring is sleeved on the outside of the picking body, and the multiple clamping claws are arranged in a ring around the periphery of the picking body, with the clamping claws positioned between the elastic constraint ring and the picking body. The top of each clamping claw is provided with a connecting ball head, which is located above the elastic constraint ring, and a connecting groove for accommodating the connecting ball head is provided on the side wall of the picking body. A clamping head is also provided at the bottom of the clamping claw, which is located below the picking body. Multiple clamping heads form a clamping gap for picking up the inner ring material, and a limiting groove for accommodating the inner ring material is provided on the side wall of each clamping head.

[0013] Furthermore, the inner wall of the pickup slot is provided with a clearance groove.

[0014] Furthermore, the inner ring feeding assembly includes: an inner ring storage cylinder, an inner ring pusher plate, and an inner ring pusher cylinder. A first discharge port communicating with the pickup slot is provided at the bottom of the inner ring storage cylinder. The inner ring pusher plate is slidably disposed inside the first discharge port. An inner ring receiving slot is provided at the end of the inner ring pusher plate near the pickup slot, and the end of the inner ring pusher plate away from the pickup slot is connected to the piston rod of the inner ring pusher cylinder.

[0015] Furthermore, the strip welding assembly includes: a rotating electrode, a support base, a slide table, and a swing electrode. The rotating electrode is disposed on the side of the strip feeding assembly near the pickup unit. The support base is vertically and flexibly disposed between the rotating electrode and the strip feeding assembly. The slide table is slidably disposed on the support base. The storage tank is disposed on the top surface of the slide table. A clamping cylinder is provided on the slide table. The swing electrode is rotatably disposed on the slide table, and the bottom end of the swing electrode is hinged to the piston rod of the clamping cylinder.

[0016] Furthermore, the banner feeding assembly includes a banner storage box and a banner pushing cylinder. A second discharge port connected to the storage trough is provided at the bottom of the banner storage box, and the piston rod of the banner pushing cylinder is placed inside the second discharge port.

[0017] Furthermore, the inside of the strip storage box is provided with two guide bars, forming a Y-shaped guide channel between the two guide bars for accommodating strip materials, and the bottom end of the Y-shaped guide channel is connected to the second discharge port.

[0018] Furthermore, the outer ring feeding assembly includes: an outer ring storage cylinder, an outer ring pusher plate, and an outer ring pusher cylinder. A third discharge port is provided at the bottom of the outer ring storage cylinder. The outer ring pusher plate is slidably disposed inside the third discharge port. An outer ring receiving groove is provided at the end of the outer ring pusher plate near the indexing plate, and the end of the outer ring pusher plate away from the indexing plate is connected to the piston rod of the outer ring pusher cylinder.

[0019] Furthermore, the outer ring welding assembly includes an upper electrode and a lower electrode. The upper electrode is vertically and vertically mounted above the indexing plate, and the lower electrode is slidably mounted between the indexing plate and the outer ring feeding assembly.

[0020] Furthermore, the pickup unit is also provided with a discharge station on its periphery. The discharge station and the second station are respectively located on both sides of the pickup unit, and the discharge station is located between the third station and the first station.

[0021] Compared with existing technologies, the circular frame processing equipment for welding wire spools described in this invention has the following advantages:

[0022] (1) The circular frame processing equipment for welding wire shafts described in this invention can pick up the inner ring material in the first station through the picking component, and can make the inner ring material pass through the second and third stations in sequence through the action of the picking unit, thereby completing the welding of the strip and the outer ring. Compared with the prior art, this processing equipment can improve the automation level of the circular frame processing of welding wire shafts, and make the processing efficiency of the circular frame meet the actual use requirements. Secondly, this processing equipment can switch the working state of the picking component through the lifting and lowering of the frame, and the picking component can rotate freely relative to the frame in the second working state. Since the strip needs to be welded radially between the inner and outer rings, the rotational freedom of the picking component in the second working state can facilitate the rotation of the workpiece during the welding process, thereby improving the processing convenience. In addition, since the picking component can remain stationary relative to the frame in the first working state, when the picking component moves between stations, the picking component in the first working state can prevent the workpiece from rotating abnormally due to the action of the picking unit, thereby facilitating the processing of the next station.

[0023] (2) The circular frame processing equipment for welding wire shafts described in this invention has multiple clamping claws on the periphery of the pickup body, and these claws are elastically constrained by an elastic constraint ring. When it is necessary to clamp the inner ring material, the elastic constraint ring will undergo elastic deformation, thereby providing sufficient clamping force to the clamping claws. In addition, the equipment also has a limiting groove on the side wall of the clamping head, which can axially limit the inner ring material inside the clamping gap, thereby preventing the inner ring material from separating from the pickup component.

[0024] (3) The circular frame processing equipment for welding wire shaft described in this invention includes a swing electrode in its strip welding assembly. During the welding of the strip and the inner ring, the swing electrode can rotate under the action of the clamping cylinder, thereby fixing the strip material in conjunction with the slide table and ensuring a good contact effect between the strip and the inner ring.

[0025] (4) The circular frame processing equipment for welding wire shafts described in this invention can drive the pickup component in the second working state to rotate through a rotating electrode and an indexing plate. The operator can set the rotation stroke of the rotating electrode and the indexing plate according to the number of strips to be welded, thereby adapting to the processing needs of circular frames of different specifications.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] A circular frame processing device for welding wire spools, used for automated processing. Figure 1 The image shows a common circular frame for welding wire spools. (Example:) Figure 1 As shown, a common circular frame for welding wire spools includes an inner ring 51 and an outer ring 53 arranged concentrically, and multiple radially arranged strips 52 are provided between the inner ring 51 and the outer ring 53.

[0042] Figures 2-8This is a schematic diagram of a circular frame processing device for welding wire spools. In this embodiment, the device includes a pickup unit, an inner ring feeding unit, a strip processing unit, and an outer ring processing unit. A first station, a second station, and a third station are arranged in a ring around the pickup unit. The inner ring feeding unit, strip processing unit, and outer ring processing unit are correspondingly located inside the first, second, and third stations. During operation, the pickup unit picks up the material to be processed and transfers the material between the stations. The inner ring feeding unit provides inner ring material to the first station for pickup. The strip processing unit provides strip material to the second station and welds it to the outside of the inner ring material on the pickup unit, forming a semi-finished product. The outer ring processing unit provides outer ring material to the third station and welds it to the outside of the semi-finished product, forming the circular frame of the welding wire spool.

[0043] Specifically, the pickup unit includes a frame 11, a drive assembly 12, and a pickup assembly. The frame 11 is vertically and flexibly mounted on the rotation shaft of the drive assembly 12, and the pickup assembly is mounted on the frame 11. It should be noted that the pickup assembly in this embodiment will operate in two different states (i.e., a first working state and a second working state) depending on its relative position to the frame 11. When the pickup assembly is at its lower limit position relative to the frame 11, it is in the first working state, where it remains relatively stationary with respect to the frame 11. When the pickup assembly is at its upper limit position relative to the frame 11, it is in the second working state, where it can rotate freely relative to the frame 11.

[0044] During operation, the frame 11 rotates and moves vertically under the drive of the drive assembly 12. The rotation of the frame 11 allows the pickup assembly to sequentially pass through the first, second, and third workstations to pick up the inner ring material, weld the banner to the inner ring material, and weld the outer ring to the banner. When the pickup assembly is aligned with any workstation, the frame 11 uses vertical movement to switch the pickup assembly between a first and second working state. This ensures that the pickup assembly enters the second working state before the work at the current workstation begins and enters the first working state after the work at the current workstation ends.

[0045] As an example and not a limitation, to achieve the switching of the working state of the pickup component, this embodiment may have a mounting hole on the frame 11 for accommodating the pickup component. A positioning groove should be provided on the inner sidewall of the mounting hole, and a positioning strip that mates with the positioning groove should be provided on the outer sidewall of the pickup component. When the pickup component rises to its limit position relative to the frame 11, the positioning strip will separate from the positioning groove, allowing the pickup component to rotate freely within the mounting hole. When the pickup component descends to its limit position relative to the frame 11, the positioning strip will enter the positioning groove, thereby circumferentially limiting the pickup component through the cooperation of the positioning strip and the positioning groove.

[0046] The above example is only one of the available structures for switching the working state of the picking component. Those skilled in the art can also choose other structures in the prior art to replace the above structure according to actual needs in order to achieve switching the working state of the picking component.

[0047] Figure 5 The exploded view of the pickup assembly in this embodiment shows that the pickup assembly may include a pickup body 131, an elastic constraint ring 133, and multiple clamping claws 132. Each clamping claw 132 has a connecting ball head 134 at its top and a clamping head 136 at its bottom. A connecting groove 135 for accommodating the connecting ball head 134 is provided on the side wall of the pickup body 131. During assembly, the elastic constraint ring 133 should be fitted over the pickup body 131. The multiple clamping claws 132 are arranged in a ring around the pickup body 131, with the claws positioned between the elastic constraint ring 133 and the pickup body 131. The connecting ball head 134 should be located above the elastic constraint ring 133 and rotatably disposed inside the connecting groove 135. The clamping head 136 should be located below the pickup body 131, and the multiple clamping heads 136 will form a clamping gap for picking up material from the inner ring.

[0048] When the pickup assembly comes into contact with the inner ring material, the inner ring material will enter the clamping gap, causing the clamping claw 132 to rotate around the connecting ball head 134 as the rotation center. At this time, the elastic constraint ring 133 sleeved on the outside of the pickup body 131 will undergo elastic deformation due to the rotation of the clamping claw 132, thereby providing clamping force to the clamping claw 132 and ensuring that the pickup assembly reliably picks up and fixes the inner ring material.

[0049] Optionally, to improve the fixing effect of the inner ring material inside the clamping gap, a limiting groove 137 for accommodating the inner ring material can also be provided on the side wall of the clamping head 136. When the inner ring material enters the clamping gap, the edge of the inner ring material will enter the limiting groove 137. At this time, the limiting groove 137 can axially limit the inner ring material to prevent the inner ring material from leaving the clamping gap.

[0050] Figure 6 The diagram shows the inner ring feeding unit, which includes a support plate 21 and an inner ring feeding assembly. The support plate 21 has a pick-up slot 22, and the inner ring feeding assembly contains multiple stacked inner ring materials. During operation, the inner ring feeding assembly pushes the stacked inner ring materials one by one into the pick-up slot 22, so that the pick-up assembly at the first workstation can pick them up.

[0051] Optionally, the inner ring feeding assembly described in this embodiment may include: an inner ring storage cylinder 24, an inner ring pusher plate 25, and an inner ring pusher cylinder 26. The bottom of the inner ring storage cylinder 24 is provided with a first discharge port communicating with the pickup groove 22. The inner ring pusher plate 25 is slidably disposed inside the first discharge port. An inner ring receiving groove is provided at the end of the inner ring pusher plate 25 near the pickup groove 22, and the end of the inner ring pusher plate 25 away from the pickup groove 22 is connected to the piston rod of the inner ring pusher cylinder 26. During operation, the inner ring pusher cylinder 26 drives the inner ring pusher plate 25 to reciprocate inside the first discharge port according to the rotation frequency of the pickup unit, thereby pushing the inner ring material at the bottom of the inner ring storage cylinder 24 into the pickup groove 22 before the pickup assembly moves to the first working position.

[0052] In addition, since the gripper 132 rotates when picking up the inner ring material, in order to avoid interference between the gripper 132 and the picking groove 22, a clearance groove 23 can be provided on the inner side wall of the picking groove 22, thereby providing space for the movement of the gripper 132 by means of the clearance groove 23.

[0053] Figure 7 This is a schematic diagram of the banner processing unit. As shown in the figure, in this embodiment, the banner processing unit includes a banner feeding assembly and a banner welding assembly. The banner feeding assembly contains multiple stacked banner materials, and the banner welding assembly is provided with a storage tank 36. During operation, the banner feeding assembly pushes the stacked banner materials one by one into the storage tank 36. Subsequently, the banner welding assembly welds the banner materials in the storage tank 36 with the inner ring materials entering the second station, thereby forming a semi-finished product.

[0054] Optionally, the banner feeding assembly may include a banner storage bin 31 and a banner pushing cylinder 32. The bottom of the banner storage bin 31 is provided with a second discharge port that communicates with the storage trough 36. The piston rod of the banner pushing cylinder 32 is placed inside the second discharge port. During operation, the banner pushing cylinder 32 drives the piston rod to reciprocate inside the second discharge port according to the rotation frequency of the pickup unit, thereby pushing the banner material at the bottom of the banner storage bin 31 into the storage trough 36 one by one.

[0055] To facilitate the arrangement of the banner materials in the banner storage bin 31 and ensure that the banner materials enter the storage trough 36 one by one under the action of the banner pushing cylinder 32, two guide bars 311 can be provided inside the banner storage bin 31. Specifically, a Y-shaped guide channel for accommodating the banner materials should be formed between the two guide bars 311, and the bottom end of the Y-shaped guide channel should be connected to the second discharge port. During use, the operator can adjust the spacing between the two guide bars 311 according to the diameter of the banner materials so that the inner diameter of the bottom end of the Y-shaped guide channel matches the diameter of the banner materials, thereby allowing multiple banner materials stacked inside the banner storage bin 31 to enter the second discharge port one by one.

[0056] Optionally, to achieve welding between the banner material and the inner ring material, the banner welding assembly described in this embodiment may include: a rotating electrode 33, a support 34, a slide 35, and a swing electrode 37. The rotating electrode 33 is disposed on the side of the banner storage box 31 near the pickup unit. The support 34 is vertically and vertically disposed between the rotating electrode and the banner storage box 31. The slide 35 is slidably disposed on the support 34. The storage trough 36 is disposed on the top surface of the slide 35. The swing electrode 37 is rotatably disposed on the slide 35, and the bottom end of the swing electrode 37 is hinged to the piston rod of the clamping cylinder 38.

[0057] After the pickup assembly transfers the inner ring material to the second station, the frame 11 descends, bringing the inner ring material into contact with the top surface of the rotary motor 33. Next, a lifting cylinder (not shown) drives the support 34 upward, so that the storage tank 36 on the slide 35 is at the same height as the inner ring material. A clamping cylinder 38 then drives the oscillating electrode 37 to rotate, clamping the strip material inside the storage tank 36. Subsequently, a pushing cylinder 39 pushes the slide 35 towards the pickup assembly, causing the end of the strip material to abut against the outer wall of the inner ring material. Therefore, when the rotary electrode 33 and the oscillating motor 37 are energized, the strip material is welded onto the inner ring material.

[0058] Furthermore, since the contact between the inner ring material and the top surface of the rotating electrode 33 enables the pickup component, which has entered the second working state, to rotate synchronously with the rotating electrode 33, after the welding of a strip material is completed, the rotating electrode 33 will drive the pickup component to rotate so that multiple strip materials are radially welded to the outside of the same inner ring material.

[0059] Figure 8The diagram shows the outer ring processing unit. In this embodiment, the outer ring processing unit includes an outer ring feeding assembly, an indexing plate 42, and an outer ring welding assembly. Multiple outer ring materials are stacked inside the outer ring feeding assembly. During operation, the outer ring feeding assembly pushes the stacked outer ring materials one by one onto the indexing plate 42. Subsequently, the outer ring welding assembly welds the outer ring materials above the indexing plate 42 with the semi-finished materials entering the third station to form the circular frame of the welding wire shaft.

[0060] Optionally, the outer ring pushing assembly may include: an outer ring storage cylinder 41, an outer ring pushing plate 43, and an outer ring pushing cylinder. The outer ring storage cylinder 41 has a third discharge port at its bottom. The outer ring pushing plate 43 is slidably disposed inside the third discharge port. An outer ring receiving groove is provided at the end of the outer ring pushing plate 43 near the indexing plate 42, and the end of the outer ring pushing plate 43 away from the indexing plate 42 is connected to the piston rod of the outer ring pushing cylinder. During operation, the outer ring pushing cylinder drives the outer ring pushing plate 43 to reciprocate inside the third discharge port according to the rotation frequency of the pickup unit. This moves the lowest outer ring material in the outer ring storage cylinder 41 onto the indexing plate 42 before the pickup assembly moves to the third station.

[0061] It should be noted that the indexing plate 42 described in this embodiment is a load-bearing component with a rotating function. A positioning protrusion for positioning the picking component should be provided at the center of the indexing plate 42, and multiple auxiliary limiting grooves for accommodating the strips of semi-finished material should be provided around the periphery of the positioning protrusion. When the picking component carrying the semi-finished material moves to the third working position, the descent of the frame 11 allows the picking component to contact the indexing plate 42, and the picking component, now in the second working state, rotates with the indexing plate 42.

[0062] To achieve the welding of the semi-finished material and the outer ring material, the outer ring welding assembly may include an upper electrode 44 and a lower electrode 45. Specifically, the upper electrode 44 should be vertically and vertically positioned above the indexing plate 42, and the lower electrode 45 should be slidably positioned between the indexing plate 42 and the outer ring feeding assembly. When the semi-finished material moves above the indexing plate 42, the lower electrode 45 will slide towards the indexing plate 42 and contact the outer ring material on the indexing plate 42. The upper electrode 44 will then descend and contact the strip on the semi-finished material, thus connecting the strip to the outer ring material. When the upper electrode 44 and the lower electrode 45 are energized, the strip on the semi-finished material will be welded to the outer ring material.

[0063] Furthermore, since the picking component can rotate synchronously with the indexing plate 42, after the welding of a strip material and the outer ring material is completed, the indexing plate 42 will drive the picking component to rotate so that multiple strip materials on the semi-finished material are welded to the same outer ring material.

[0064] As an optional implementation of this embodiment, the operator can add a rotation indexing controller to the rotating electrode 33 and the indexing disk 42 according to actual needs, thereby controlling the stroke of the rotating electrode 33 and the indexing disk 42 in each rotation. For example, when eight strips need to be set inside the circular frame of the welding wire shaft, the rotating electrode 33 and the indexing disk 42 should continuously rotate eight times in equal increments during the same working process, so that the eight strips are evenly set between the inner and outer rings.

[0065] As another optional implementation of this embodiment, to further improve the production efficiency of the circular frame of the welding wire spool, a discharge station can also be provided around the periphery of the pickup unit. Specifically, the discharge station and the second station should be respectively located on both sides of the pickup unit, and the discharge station should be located between the third station and the first station, so that the operator can easily remove the processed circular frame of the welding wire spool at the fourth station. Correspondingly, the pickup unit should also include four pickup components, so that all four stations have processing capabilities at the same time.

[0066] The effects of the above solution are explained below:

[0067] This embodiment provides a circular frame processing device for welding wire spools. It can transfer workpieces between various workstations via the action of the pick-up unit, and can supply inner ring material through an inner ring feeding unit, weld the strip to the inner ring through a strip processing unit, and weld the outer ring to the semi-finished material through an outer ring processing unit. Therefore, it can significantly improve the processing efficiency of the circular frame of the welding wire spool. Secondly, this device can grip the inner ring material through the pick-up component, and the working state of the pick-up component can be switched by raising and lowering the frame, thus facilitating operation. Furthermore, this device can clamp the strip through a swing electrode and position the outer ring and semi-finished material through an indexing plate, thereby improving the welding effect.

[0068] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
