Description

Technical Field

[0001] The present application relates to the technical field of insulating tape welding, and in particular to an external insulating tape welding machine. Background Art

[0002] External insulating tape is a common production material and is widely used in the field of motor production. The production process of external insulating tape includes welding process, which is a process for converting the external insulating tape from an insulating sheet to an insulating ring.

[0003] In the prior art, in the welding process of the external insulating tape, a welding machine is usually used to weld the workpiece. The welding machine generally includes a feeding mechanism, a shearing mechanism, a flip clamp mechanism and a welding mechanism. In actual operation, the workpiece is fed smoothly under the action of the feeding mechanism. Two flip clamp mechanisms are provided, one of which clamps one end of the insulating sheet. When the length of the workpiece meets the shearing length, the other clamp clamp clamps the pre-sheared end of the insulating sheet. The shearing mechanism shears the workpiece. Subsequently, the two flip clamp mechanisms flip the two ends of the workpiece in turn and place them on the welding platform of the welding mechanism so that the two ends of the workpiece fit together. The welding mechanism then welds the two ends of the workpiece after fitting together. After the welding of the workpieces is completed, the workpieces need to be stacked one by one to facilitate the storage and management of the workpieces. The welding speed of the workpieces is slow, which affects the later material collection and processing of the workpieces, and the production efficiency is low. Summary of the invention

[0004] In order to improve the production efficiency of external insulating tape, the present application provides an external insulating tape welding machine.

[0005] The present application provides an external insulating tape welding machine, which adopts the following technical solution:

[0006] An external insulating tape welding machine comprises a feeding mechanism, a shearing mechanism and a welding mechanism, as well as a guide rail conveying mechanism for guiding a workpiece, wherein the guide rail conveying mechanism is located at the output end of the feeding mechanism, and a clamping mechanism for clamping one end of the workpiece to the welding mechanism is provided at the output end of the guide rail conveying mechanism, the shearing mechanism is located between the feeding mechanism and the guide rail conveying mechanism, and a flipping clamp mechanism is provided at one end of the shearing mechanism away from the feeding mechanism, the flipping clamp mechanism is used to clamp the pre-sheared end of the workpiece and flip and fit the sheared end of the workpiece to one end of the workpiece clamped by the clamping mechanism, and the welding mechanism is used to weld the two ends of the workpiece after bonding.

[0007] By adopting the above technical scheme, when welding operation is required, the feeding mechanism conveys the workpiece to the guide rail conveying mechanism, and the workpiece moves under the guidance of the guide rail conveying mechanism. When one end of the workpiece moves to the welding mechanism, the clamping mechanism is started, and the clamping mechanism clamps the end moved to the welding mechanism. At the same time, during the clamping process of the workpiece, the workpiece is continuously fed. When the length of the workpiece meets the required length, the flipping clamp mechanism clamps the pre-sheared end of the workpiece, the feeding mechanism stops feeding the workpiece, and the shearing mechanism shears the pre-sheared end of the workpiece. After the shearing is completed, the flipping clamp mechanism flips the sheared end of the workpiece so that the sheared end of the workpiece is bonded with the clamping end of the workpiece by the clamping mechanism, and the welding mechanism welds the two ends of the workpiece after bonding. There is no need to wait for the workpiece shearing to be completed and then flip the two ends of the workpiece one by one. Instead, the workpiece is directly moved to the welding mechanism, and then the clamping mechanism is used to clamp the workpiece, thereby reducing the workpiece flipping time, improving the workpiece welding efficiency, and thus improving the production efficiency.

[0008] Optionally, it also includes a workbench, the welding mechanism includes a welding table, a welding plate and a welding assembly, the welding table is fixed to the workbench, the welding plate is installed on the welding table, the welding assembly is used to weld the workpiece attached to the welding plate, the guide rail conveying mechanism includes a guide rail conveying member and a conveying driving member, the conveying driving member is used to convey the guide rail conveying member to be attached to the welding table, the conveying driving member is fixed to the workbench, and a conveying channel for moving the workpiece is formed between the guide rail conveying member and the welding plate.

[0009] By adopting the above technical solution, the workpiece moves in the conveying channel formed by the guide rail conveyor and the welding plate, so that the conveying channel is composed of two plates, which is convenient for the later inspection of the conveying channel, improves the smoothness of the conveying channel, reduces the possibility of the workpiece being stuck in the conveying channel, improves the stability of the workpiece movement, and thus improves the welding efficiency of the workpiece.

[0010] Optionally, the guide rail conveyor is connected to a sliding plate, the sliding plate is rotatably connected to a sliding roller, the workbench is connected to a slide rail, and the sliding roller is in rolling contact with the slide rail.

[0015] By adopting the above technical solution, when the workpiece moves in the conveying channel, the limiting component limits the moving direction of the workpiece, thereby reducing the possibility of deviation of the welding position caused by the deviation of the workpiece in the conveying channel, thereby reducing the possibility of scrapping the workpiece and improving the production efficiency of the workpiece.

[0016] Optionally, the limit assembly includes a limit member, a push member, a push roller and a return spring, the limit member is slidingly connected to the guide rail conveying member, the push member is slidingly connected to the guide rail conveying member, the push member passes through the side of the guide rail conveying member close to the welding table, the push roller is rotatably connected to the push member, the push roller is in rolling contact with the limit member, the push member is fixed to the return spring, and the return spring is fixed to the guide rail conveying member.

[0017] By adopting the above technical solution, when the guide rail conveyor moves to the welding table, the pushing member is in close contact with the welding table. As the guide rail conveyor approaches the welding table, the pushing member causes the limiting member to slide on the guide rail conveyor under the rotation of the pushing roller, thereby limiting the workpiece. After the guide rail conveyor moves away from the welding table, the reset spring resets the pushing member, thereby resetting the limiting member.

[0018] Optionally, along the workpiece conveying direction, the inlet end of the conveying channel is in an eight-shaped convergent shape.

[0019] By adopting the above technical solution, the stability of the workpiece entering the conveying channel is improved, and the feeding speed of the workpiece in the conveying channel is increased.

[0020] Optionally, a push plate is provided on the top of the welding plate, and the push plate slides with the welding table through a sliding drive member. The workbench is provided with a discharge port, and the discharge port is located at the bottom of the welding plate.

[0021] By adopting the above technical solution, before the workpiece is welded, the guide rail conveyor is away from the welding table. After the workpiece is welded, the clamping mechanism and the flip clamp mechanism stop clamping the workpiece, the workpiece is hung on the welding plate, the sliding drive member drives the push plate to move, the workpiece falls from the welding plate, and then is discharged from the discharge port, thereby increasing the discharge speed.

The pushing plate is slidably connected with the material receiving rack. The material gathering member is fixed to the pushing plate. The material gathering member is in a U shape. The opening direction of the material gathering member faces the discharge end of the funnel. The output end of the pushing driving member is fixed to the pushing plate. The pushing driving member is fixed to the material receiving rack.

The material gathering member is in a U shape, keeping the workpieces in a circular shape close to a circle in the material gathering member, facilitating the sleeving of the workpieces on the material receiving rollers and improving the sleeving speed of the workpieces on the material receiving rollers.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. When welding operations need to be performed, the feeding mechanism conveys the workpieces to the guide rail conveying mechanism. The workpieces move under the guidance of the guide rail conveying mechanism. When one end of the workpiece moves to the welding mechanism, the clamping mechanism is started. The clamping mechanism clamps one end that has moved to the welding mechanism. Meanwhile, during the clamping process of the workpiece, the workpiece continues to be fed. When the length of the workpiece meets the required length, the flipping clamp mechanism clamps the pre-shearing end of the workpiece. The feeding mechanism stops feeding the workpiece. The shearing mechanism shears the pre-shearing end of the workpiece. After shearing is completed, the flipping clamp mechanism flips the shearing end of the workpiece, making the shearing end of the workpiece fit with the clamping end of the workpiece clamped by the clamping mechanism. The welding mechanism welds the two ends of the workpiece after fitting, without waiting for the workpiece to be sheared and then flipping the two ends of the workpiece sequentially. Instead, the workpiece directly moves to the welding mechanism, and then the clamping mechanism clamps the workpiece, reducing the flipping time of the workpiece, improving the welding efficiency of the workpiece, and thus improving the production efficiency;

[0028] 2. The workpiece moves in the conveying channel formed by the guide rail conveyor and the welding plate, so that the conveying channel is composed of two plates, which is convenient for later inspection of the conveying channel, improves the smoothness of the conveying channel, reduces the possibility of the workpiece being stuck in the conveying channel, improves the movement stability of the workpiece, and thus improves the welding efficiency of the workpiece;

[0029] 3. When the guide rail conveyor moves to the welding table, the push member is in close contact with the welding table. As the guide rail conveyor approaches the welding table, the push member causes the limit member to slide on the guide rail conveyor under the rotation of the push roller, thereby limiting the workpiece. After the guide rail conveyor moves away from the welding table, the reset spring resets the push member, thereby resetting the limit member. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The embodiment of the present application discloses an external insulating tape welding machine.

[0038] Reference Figure 1 and Figure 2 A welding machine for external insulating tape comprises a workbench 1, a feeding mechanism 2, a shearing mechanism 3, a clamping mechanism 4 and a welding mechanism 5, and also comprises a guide rail conveying mechanism 6 for guiding a workpiece. Along the moving track of the workpiece, the feeding mechanism 2, the guide rail conveying mechanism 6, the clamping mechanism 4 and the welding mechanism 5 are sequentially arranged on the top of the workbench 1, the clamping mechanism 4 is used to convey the workpiece to one end of the welding mechanism 5 for clamping, the shearing mechanism 3 is located between the feeding mechanism 2 and the guide rail conveying mechanism 6, and a flip clamp mechanism 7 is arranged at one end of the shearing mechanism 3 away from the feeding mechanism 2, the flip clamp mechanism 7 is used to clamp the pre-sheared end of the workpiece, and flip and fit the sheared end of the workpiece with one end of the workpiece clamped by the clamping mechanism 4, and the welding mechanism 5 is used to weld the two ends of the workpiece after bonding.

[0039] When welding the workpiece, the workpiece is fed under the action of the feeding mechanism 2, and the feeding mechanism 2 transmits the workpiece to the guide rail conveying mechanism 6. The workpiece moves to the welding mechanism 5 under the guidance of the guide rail conveying mechanism 6, and the clamping mechanism 4 is started. The clamping mechanism 4 clamps the end moved to the welding mechanism 5, and the workpiece is continuously fed. When the length of the workpiece meets the required length, the flipping clamp mechanism 7 clamps the pre-sheared end of the workpiece, and then the shearing mechanism 3 shears the workpiece. After the shearing is completed, the flipping clamp mechanism 7 flips the sheared end of the workpiece so that the sheared end of the workpiece is fitted with the clamping end of the workpiece by the clamping mechanism 4, and then the welding mechanism 5 welds the two ends of the workpiece. There is no need to wait for the workpiece shearing to be completed and then flip the two ends of the workpiece in turn. Instead, the workpiece is directly moved to the welding mechanism 5, and then the clamping mechanism 4 is used to clamp the workpiece, which reduces the workpiece flipping time, improves the workpiece welding efficiency, and thus improves the production efficiency.

[0040] The feeding mechanism 2 includes a feeding frame 21, a feeding driving member 22, a feeding roller 23 and a pressure roller 24. The feeding frame 21 is fixed to the top wall of the workbench 1, the feeding driving member 22 is fixed to the top wall of the workbench 1, the feeding roller 23 is rotatably connected to the feeding frame 21, the feeding driving member 22 is used to drive the feeding roller 23 to roll, and the pressure roller 24 is rotatably arranged on the top of the feeding roller 23. There is a gap between the pressure roller 24 and the feeding frame 21, and the gap is used to flatten the workpiece and feed the workpiece to improve the feeding stability of the workpiece. In this embodiment, the feeding driving member 22 adopts a driving motor.

[0041] In order to improve the practicality of the feeding mechanism 2 and facilitate the feeding operation of workpieces with inconsistent thicknesses, the top of the feeding rack 21 is rotatably connected with an adjusting member 25, and the end of the adjusting member 25 away from the feeding rack 21 is threadedly connected with an adjusting rack 26. The feeding rack 21 is provided with a notch, and the adjusting member 25 is inserted into the notch of the feeding rack 21. The adjusting member 25 is abutted against the groove wall of the notch of the feeding rack 21, and the pressure roller 24 is rotatably connected to the adjusting rack 26.

[0042] The welding mechanism 5 includes a welding table 51, a welding plate 52 and a welding assembly. The welding table 51 is fixed to the top wall of the workbench 1, and the welding plate 52 is installed on the welding table 51. The welding assembly includes a welding frame 53, a lifting frame 54, a lifting drive 55 and a welder 56. The welding frame 53 is fixed to the top wall of the workbench 1, and the lifting frame 54 is slidably connected to the welding frame 53. The lifting drive 55 is installed on the top wall of the welding frame 53. The output end of the lifting drive 55 is fixed to the lifting frame 54, and the lifting frame 54 is fixed to the welder 56. The welder 56 is used to weld the workpiece attached to the welding plate 52. The welding head of the welder 56 faces the welding plate 52, and the welding plate 52 is located at the bottom of the welding frame 53. In this embodiment, the lifting drive 55 adopts a cylinder, and the welder 56 adopts an ultrasonic welding head. The welding plate 52 and the welding head of the welder 56 match.

[0043] When welding the workpiece, the lifting drive 55 is started, and the lifting drive 55 drives the lifting frame 54 to move up and down, so that the welding head of the welder 56 moves toward the workpiece on the welding plate 52, and welds the two ends of the workpiece after bonding.

[0044] In order to facilitate the unloading operation of the workpiece and improve the production efficiency, a discharge port 11 is opened through the top wall of the workbench 1. The discharge port 11 is located at the bottom of the welding plate 52 and is opened in the lifting direction of the welder 56. A pushing plate 521 is arranged on the top of the welding plate 52. The pushing plate 521 slides with the welding table 51 through the sliding driving member 522. The horizontal movement direction of the pushing plate 521 is toward the discharge port 11. The bottom wall of the pushing plate 521 is against the top wall of the welding plate 52. The sliding driving member 522 is fixed to the welding table 51. The guide rail conveying mechanism 6 slides with the workbench 1. The sliding driving member 522 and the guide rail conveying mechanism 6 are respectively located on both sides of the discharge port 11 in the feeding direction of the feeding mechanism 2. In this embodiment, the sliding driving member 522 adopts a cylinder.

[0045] When performing welding operations, the guide rail conveying mechanism 6 conveys it to fit the welding table 51, and the welding plate 52 slides to just below the welding head of the welder 56 under the driving action of the sliding drive member 522. When the workpiece moves onto the welding plate 52, the clamping mechanism 4 clamps the workpiece, and then the guide rail conveying mechanism 6 slides toward the end away from the welding table 51. After the welding of the workpiece is completed, the clamping mechanism 4 stops clamping the workpiece, and the flip clamp mechanism 7 stops clamping the workpiece. The sliding drive member 522 drives the push plate 521 to move toward one end of the discharge port 11, and the push plate 521 pushes the workpiece, and the workpiece falls from the welding plate 52 to the discharge port 11 for discharge.

[0046] The guide rail conveying mechanism 6 includes a guide rail conveying member 61 and a conveying driving member 62. The conveying driving member 62 is used to convey the guide rail conveying member 61 to fit the welding table 51. The conveying driving member 62 is fixed to the workbench 1. A conveying channel for the workpiece to move is formed between the guide rail conveying member 61 and the welding plate 52. When the workpiece is fed under the joint action of the feed roller 23 and the pressure roller 24, the workpiece moves along the conveying channel.

[0047] In order to facilitate the smooth transportation of the guide rail conveyor 61 to fit the welding table 51, the bottom of the guide rail conveyor 61 is fixedly connected to a sliding plate 63, and the bottom of the sliding plate 63 is rotatably connected to a sliding roller. In order to make the moving direction of the guide rail conveyor 61 directional and reduce the possibility of deviation of the conveying channel causing unstable movement of the workpiece and affecting the welding process, a slide rail 64 is fixedly connected to the top of the workbench 1, and the sliding roller is in rolling contact with the slide rail 64.

[0048] The conveying channel is arc-shaped, and the inlet and outlet ends of the conveying channel are tangent to the horizontal plane, which enhances the stability of feeding and discharging of workpieces in the conveying pipeline and improves the feeding speed of the workpieces.

[0049] In order to further enhance the stability of the workpiece entering the conveying channel, the inlet end of the conveying channel is in an eight-shaped gathering shape along the workpiece conveying direction.

[0050] Refer to 2 and Figure 3The guide rail conveying member 61 is slidably connected to the limit assembly, and the limit assembly is located on the side of the guide rail conveying member 61 close to the welding plate 52. The limit assembly includes a limit member 65, a push member 66, a push roller 67 and a return spring 68. The limit member 65 is used to limit the moving direction of the workpiece. The limit member 65 is slidably connected to the guide rail conveying member 61. One end of the limit member 65 is hemispherical. The push member 66 is slidably connected to the guide rail conveying member 61. The guide rail conveying member 61 is provided with a push groove. The push member 66 is inserted in the push groove and slides with the guide rail conveying member 61. The extension direction of the push member 66 is consistent with the sliding direction of the guide rail conveying member 61. The extension direction is perpendicular to the extension direction of the pushing member 66. The end of the pushing member 66 away from the limiting member 65 passes through the side of the guide rail conveying member 61 close to the sliding table. The pushing roller 67 is rotatably connected to the end of the pushing member 66 close to the limiting member 65. The pushing roller 67 is in rolling contact with the hemispherical end of the limiting member 65. The side groove wall of the pushing groove is provided with a limiting groove. The side wall of the pushing member 66 is fixedly connected with a protrusion 69. The protrusion 69 is located in the limiting groove. The bottom wall of the protrusion 69 is against the bottom groove wall of the limiting groove. The protrusion 69 of the pushing member 66 is fixed to the reset spring 68. The end of the reset spring 68 away from the pushing member 66 is fixed to the guide rail conveying member 61.

[0051] When the guide rail conveyor 61 moves to fit against the welding table 51, the push member 66 contacts the welding table 51, and as the guide rail conveyor 61 moves, the push member 66 slides with the guide rail conveyor 61, and the push member 66 moves toward the limit member 65 when sliding, so that the push roller 67 rolls in contact with the limit member 65, and the push roller 67 rolls to drive the limit member 65 to push toward the welding plate 52. At this time, the reset spring 68 is in a compressed state. When the workpiece moves in the conveying channel, the limit member 65 sliding from the guide rail conveyor 61 limits the movement of the workpiece, thereby reducing the possibility of welding dislocation caused by the deviation of the workpiece movement direction, further reducing the possibility of the workpiece being scrapped and needing to be re-produced due to the dislocation of the welding position of the workpiece, and improving the workpiece production efficiency.

[0052] The clamping mechanism 4 includes a clamping drive 41 and a clamping plate 42. The clamping drive 41 is fixed to the top wall of the welding table 51. The output end of the clamping drive 41 is fixed to the clamping plate 42. The clamping plate 42 is located at the top of the welding plate 52, and the clamping plate 42 is located at the outlet end of the conveying channel. The clamping drive 41 is used to drive the clamping plate 42 to clamp the workpiece to the top wall of the welding plate 52. In this embodiment, the clamping drive 41 adopts a cylinder.

[0053] When the workpiece moves out from the outlet end of the conveying channel, the clamping driving member 41 is activated. The clamping driving member 41 drives the clamping plate 42 to clamp the workpiece. At this time, the conveying driving member 62 drives the guide rail conveying member 61 away from the welding table 51, and the workpiece continues to feed under the combined action of the feeding roller 23 and the pressure roller 24 until the length of the workpiece meets the requirements, and then the shearing mechanism 3 shears the workpiece.

[0054] The shearing mechanism 3 includes a shearing base 31, a shearing knife 32, a sliding member 33 and a shearing driving member 34. The shearing base 31 is fixed to the top wall of the workbench 1. The shearing base 31 is located at the end of the conveying direction of the feeding mechanism 2. The shearing knife 32 is rotatably connected to the shearing base 31. A sliding groove is formed at one end of the shearing knife 32 away from the shearing base 31. The sliding member 33 is inserted into the sliding groove, and the sliding member 33 slides in the sliding groove. The extending direction of the sliding groove is consistent with the extending direction of the shearing knife 32. The shearing driving member 34 is fixed to the top wall of the workbench 1, and the output end of the shearing driving member 34 is fixed to the sliding member 33. The output direction of the output end of the shearing driving member 34 is vertically upward. In this embodiment, the shearing driving member 34 is a cylinder.

[0055] When feeding the workpiece, the shearing driving member 34 is activated. The shearing driving member 34 drives the sliding member 33 to rise, and the sliding member 33 slides in the sliding groove, making the shearing knife 32 in an open state. The workpiece passes through between the shearing blade and the shearing base 31 under the combined action of the feeding roller 23 and the pressure roller 24; when feeding the workpiece, the shearing driving member 34 is activated. The shearing driving member 34 drives the sliding member 33 to descend, and the sliding member 33 slides in the sliding groove, making the shearing knife 32 close to the shearing base 31 to shear the workpiece.

[0056] Refer to Figure 1 and Figure 4 As shown in, a discharge hopper 8 is provided at the discharge port 11. The feeding end of the discharge hopper 8 is fixed to the bottom wall of the tabletop of the workbench 1. A funnel 81 is fixedly connected to the bottom of the discharge hopper 8. The discharge hopper 8 is communicated with the funnel 81. A receiving rack 9 is provided at the bottom of the funnel 81. The receiving rack 9 is connected with a plurality of receiving rollers 91 for sleeving the workpiece. The receiving rollers 91 are located at one end of the receiving rack 9 away from the funnel 81. In this embodiment, the number of the receiving rollers 91 is two. The receiving rack 9 is slidably connected with a material gathering assembly for pushing the workpiece to the receiving rollers 91. The material gathering assembly includes a pushing plate 92, a material gathering member 93 and a pushing driving member 94. The pushing plate 92 slides on the receiving rack 9. The material gathering member 93 is fixed to the side of the pushing plate 92 close to the receiving rollers 91. The material gathering member 93 is in a U shape, and the opening direction of the material gathering member 93 faces the discharge end of the funnel 81. The output end of the pushing driving member 94 is fixed to the pushing plate 92, and the pushing driving member 94 is fixed to the receiving rack 9. In this embodiment, the pushing driving member 94 is a cylinder.

[0057] When collecting workpieces, the workpieces fall from the discharge port 11, pass through the discharge hopper 8 and the funnel 81 in sequence, and finally fall into the material collecting member 93. The pushing driving member 94 is started, and the material collecting assembly moves the workpieces to the collecting roller 91, so that the workpieces are sleeved on the collecting roller 91. The material collecting member 93 is in a U shape. The workpieces fall into the material collecting member 93, and the inner peripheral wall of the material collecting member 93 supports the workpieces, keeping the workpieces in an annular shape, facilitating the accurate placement of the workpieces on the collecting roller 91 and improving the workpiece stacking efficiency.

[0058] The material collecting assembly is located at the discharge end of the funnel 81. A stacking assembly is arranged at the top of the collecting roller 91. The stacking assembly is located at one end of the collecting frame 9 away from the material collecting assembly. The stacking assembly includes a stacking driving member 95 and a stacking member 96. The stacking driving member 95 is fixed to the collecting frame 9, and the output end of the stacking driving member 95 is fixed to the stacking member 96. The stacking member 96 is in an inverted trapezoid shape, and the extending direction of the stacking member 96 is consistent with the extending direction of the collecting roller 91. The stacking point of the stacking member 96 is located between adjacent collecting rollers 91. The stacking member 96 is located at the top of the collecting roller 91. The stacking member 96 is used for stacking multiple workpieces. The collecting frame 9 is slidably connected with a pushing assembly. The material collecting moving direction of the material collecting assembly is opposite to the pushing moving direction of the pushing assembly. The pushing assembly includes a pushing plate 97 and a pushing driving member 98. The pushing plate 97 is slidably connected with the collecting roller 91, and the output end of the pushing driving member 98 is fixed to the pushing plate 97. The pushing driving member 98 is fixed to the collecting frame 9. The collecting frame 9 is provided with a collecting port, and the collecting port is located directly below the collecting roller 91. In this embodiment, the stacking driving member 95 uses a cylinder, and the pushing driving member 98 uses a cylinder.

[0059] The stacking driving member 95 is started, and the stacking driving member 95 drives the stacking member 96 to press down a part of the workpieces between adjacent collecting rollers 91, facilitating the sequential stacking of other workpieces on the workpieces already sleeved on the collecting roller 91. When the stacking quantity of the workpieces on the collecting roller 91 meets the requirements, the pushing driving member 98 is started, and the pushing driving member 98 drives the pushing plate 97 to push the workpieces off the collecting roller 91. The workpieces are discharged from the collecting port, facilitating the collection of the workpieces, improving the workpiece stacking efficiency, and further improving the workpiece production efficiency.

[0060] The implementation principle of an external insulating tape welding machine in an embodiment of the present application is as follows: the feed roller 23 and the pressure roller 24 work together to convey the workpiece to the conveying channel formed by the welding table 51 plate and the guide rail conveying member 61, and the workpiece moves along the conveying channel. When the workpiece moves to the welding plate 52, the clamping drive 41 drives the clamping plate 42 to clamp the workpiece, and the conveying drive 62 drives the guide rail conveying member 61 away from the welding table 51. At the same time, the workpiece is continuously fed. When the length of the workpiece meets the requirements, the flipping clamp mechanism 7 clamps the pre-shearing end of the workpiece, and the shearing drive 34 drives the shearing knife 32 to shear the workpiece. Then, the flipping clamp mechanism 7 flips the shearing end of the workpiece so that the clamping end and the shearing end of the workpiece are attached to the welding plate 52, and the welding drive drives the welder 56 to weld the two ends of the workpiece, thereby improving the welding efficiency of the workpiece, thereby improving the production efficiency of the workpiece.

[0061] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and do not limit the protection scope of the present application in turn. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
