Description

Technical Field

[0001] This application relates to the field of 3D printing technology, specifically to a printing filament extrusion welding device. Background Technology

[0002] With the increasing application of FDM (Fused Deposition Modeling) 3D printing technology, there are also situations where it is necessary to weld and splice the printing filaments. Related patent literature has provided some solutions. For example, the patent application No. 2022221023624, entitled "A 3D Printing Filament Joining Device," uses a method of directly welding the filament joint with a heated blade. However, this method is prone to leaving saucer-shaped molten residue at the joint, resulting in poor performance.

[0003] For example, the "Consumable Welding Device" with application number 2024201908268 uses Teflon tubing as the heat transfer medium for the wire joint. After the wire is welded, the Teflon tubing needs to be cut, which is inconvenient. In addition, since the wire is welded by hand, the first and second caps used will obstruct the user's view of the wire welding process, which may also have a negative impact on the unstable welding effect.

[0004] Therefore, there is a need for a device that provides good splicing effect, is portable, and can achieve semi-automatic clamping, conveying, extrusion, and welding of wires. Summary of the Invention

[0005] The embodiments of this application aim to provide a device that has good splicing effect, is portable, and can realize semi-automatic clamping, conveying, extrusion and welding of wires.

[0006] This application provides a printing wire extrusion welding device, comprising: a housing, a welding assembly, a clamping and pushing assembly, a pressure rod, and a release rod; the upper part of one side of the housing is provided with an installation port and at least two sliding holes; the clamping and pushing assembly is disposed inside the housing; the pressure rod and the release rod slide in the sliding holes.

[0007] The welding assembly includes two sets of separable heat-conducting sheets, each set of which has a wire groove. The wire grooves are joined together to form a through cavity for embedding two wire sections. An electric heating element is attached and fixed to the heat-conducting sheet. The electric heating element is energized and heated to conduct heat to the heat-conducting sheet for thermal welding of the wire joint.

[0008] The clamping and pushing assembly includes a sliding shell, a driving block, a sliding bottom assembly, a wire clamping assembly, a trigger block, and a horizontal push spring. The sliding bottom assembly includes a base and a deflection base plate. One end of the deflection base plate is provided with a protruding tooth. The sliding shell has a force-receiving driving part on its left outer wall in the X-axis direction. A horizontal push spring is provided between the right outer wall of the sliding shell in the X-axis direction and the inner wall of the outer shell. The wire clamping assembly includes a lever wire clamp and a lever latch. The lever wire clamp and the lever latch are disposed on the sliding shell. The upper end of the lever wire clamp is provided with a movable clamp. The movable clamp protrudes from the mounting port and is used to clamp the wire.

[0009] Pressing the lever along the Z-axis drives the drive block, which in turn drives the lever clamp to deflect and open the movable clamp. The lever latch locks the lever clamp in place. The drive block also drives the force-receiving drive unit, which converts the downward pressure into a lateral thrust, causing the sliding shell to slide outward along the X-axis on the base and compress the lateral push spring. When the sliding shell reaches its endpoint along the X-axis, the protruding teeth stop and fix the sliding shell.

[0010] Pressing the release lever along the Z-axis drives the actuating block; the actuating block drives the lever latch to release the lever clamp, thereby closing the movable clamp to hold the wire; the actuating block also drives the deflection base plate to deflect and disengage the convex tooth from the sliding shell; the horizontal push spring pushes the sliding shell and the wire clamping assembly along the X-axis to slide towards the connector, so that the wire held on the movable clamp is conveyed and squeezed towards the connector.

[0011] Furthermore, the upper part of the sliding shell is provided with a groove; the movable clamp is provided with a wire pressing groove; the lower end of the lever wire pressing clamp is provided with a pressing platform; the lever wire pressing clamp is provided with a spring in the Y-axis direction and a locking groove in the X-axis direction; the lever locking groove is provided with a spring in the Z-axis direction and a locking tooth in the X-axis direction; one end of the lever locking groove is connected to the spring, and the other end is provided with a pressing platform, and the pressing platform can drive the pressing platform to press down together; the lever wire pressing clamp and the lever locking groove are each connected to the sliding shell by the X-axis.

[0012] Pressing the pressing platform along the Z-axis causes the pressing platform to move downwards as a lever, and the locking teeth engage with the locking groove; the lever locking, with the help of the spring force, keeps the locking teeth locked against the locking groove, and keeps the movable clamp open.

[0013] Pressing the touch platform downwards along the Z-axis creates a lever motion, causing the locking teeth to disengage from the locking groove. The lever-operated wire clamp, aided by the spring force, unlocks the locking teeth from the locking groove, while simultaneously pressing the movable clamp and wire clamping groove against the inner wall of the groove to hold the wire.

[0014] The aforementioned printing wire extrusion welding device has a driving inclined surface at the lower part of the driving block; the driving inclined surface and the force-receiving driving part form a kinematic pair.

[0017] The aforementioned printing wire extrusion welding device includes an actuating block comprising a spring positioning rod, a contact platform, a contact rod, and a spring; a spring positioning rod is provided at the lower part of the actuating block, and the spring is disposed on the spring positioning rod; a contact platform of a first length and a contact rod of a second length are also provided at the lower part of the actuating block; the upper part of the actuating block is connected to the release rod; generally, the first length is less than the second length.

[0018] Pressing the release lever along the Z-axis drives the actuating block to move downward. The contact plate first contacts and presses the contact platform to make a downward lever movement, so that the locking teeth unlock the locking groove. At the same time, the movable clamp and the wire pressing groove are pressed against the inner wall of the groove to hold the wire.

[0019] Pressing the release lever along the Z-axis direction continues to drive the actuating block downwards. The actuating lever then contacts and presses the deflection base plate to deflect downwards around the Y-axis, causing the convex teeth to release the obstruction of the bottom of the sliding shell. The horizontal push spring acts on the sliding shell, causing the sliding shell and the wire clamping assembly to slide in the limiting area along the X-axis towards the connector, so that the wire clamped on the movable clamp is conveyed and squeezed towards the connector.

[0020] The aforementioned printing wire extrusion and welding device further includes a sliding assembly and an elastic fastening module; wherein, the sliding assembly includes: a first slider, a second slider, a slide rail, a flip hinge block, and rollers; the elastic fastening module includes a movable block, a support spring, and a spring seat; the flip hinge block is provided with rollers; the spring seat is fixed to the outer shell; the movable block is connected to the spring seat through the support spring.

[0071] In the figure, the wire clamping assembly 34 includes a lever wire clamp 341 and a lever latch 342; a movable clamp 3411 is disposed at the upper end of the lever wire clamp 341, and a pressing platform 3414 is disposed at the other end of the lever wire clamp 341; a wire clamping groove 3412 is disposed on the movable clamp 3411; a spring 101 in the Y-axis direction and a latching groove 3413 in the X-axis direction are disposed on the lever wire clamp 341; a spring 102 in the Z-axis direction and a latching tooth 3421 in the X-axis direction are disposed on the lever latch 342; one end of the lever latch 342 is connected to the spring 102, and the other end is provided with a pressing platform 3422, and the pressing platform 3414 can drive the pressing platform 3422 to press down together.

[0072] In the figure, the sliding bottom assembly 33 includes a base 331, a deflection base plate 332, and a spring 105; a limit area 3311 is provided on the base 331; the deflection base plate 332 is connected to the base 331 via a Y-axis; the deflection base plate 332 deflects around the Y-axis, and the spring 105 is used for resetting; specifically, in this embodiment, the spring 105 is a torsion spring; one end of the deflection base plate 332 is provided with a tooth 3321.

[0073] Pressing the lever 320 along the Z-axis direction pushes the drive block 32, which in turn drives the touch platform 3422 to move downwards as a lever. The locking teeth 3421 engage with the locking groove 3413. With the help of the spring force of the spring 102, the lever locking teeth 3421 are locked to the locking groove 3413, keeping the movable clamp 3411 open.

[0074] While pressing the lever 320 along the Z-axis, the drive block 32 is driven downward to provide downward driving force. The drive block 32 also drives the roller 313 through the drive inclined surface 321, converting the downward pressure into a lateral pushing force, causing the sliding shell 31 to slide outward along the X-axis in the limiting area 3311 and compress the transverse push spring 36. When the sliding shell 31 slides outward along the X-axis to the end point, the convex tooth 3321 blocks and fixes the sliding shell 31, and keeps the transverse push spring 36 compressed. The specific blocking contact point is located below the force-driven part 310 in this figure.

[0075] Specifically, when the sliding housing 31 slides outward along the X-axis, in order to prevent the protruding teeth 3321 from hooking onto the bottom of the sliding housing assembly 31, reference is made to... Figure 9 A small inclined surface 312 is provided at the bottom of the sliding shell 31, which makes the sliding action of the protruding tooth 3321 smoother; preferably, an inclined surface structure is also provided on the protruding tooth 3321 in this figure, which can cooperate with the small inclined surface 312 to achieve smooth sliding.

[0076] The user can insert the two wires 200 on the left and right into the aforementioned wire groove 23 to form a through cavity. The wire connectors 201 need to be in contact with each other. Then, place the wire 200 on the right side into the wire crimping groove 3412 and keep it in the ready position.

[0077] Pressing the release lever 350 along the Z-axis direction drives the actuating block 35 to move downwards, in conjunction with... Figure 9 The shorter contact plate 352 first contacts and presses the contact platform 3422 to make a downward lever movement, so that the locking tooth 3421 disengages from the locking groove 3413; then, under the action of the spring 101, the movable clamp 3411 and the wire pressing groove 3412 are pressed against the inner wall of the groove 311, so that the wire 200 placed on the right side can be clamped and fixed.

[0078] Continue pressing the release lever 350 downwards along the Z-axis direction, further driving the actuating block 35 to move downwards, in conjunction with... Figure 9 The longer contact rod 353 then contacts and presses the deflection base plate 332 to deflect downward about the Y-axis, thereby releasing the obstruction of the tooth 3321 to the bottom of the sliding shell 31.

[0079] The push spring 36 acts on the sliding shell 31, causing the sliding shell 31 and the wire clamping assembly 34 to slide in the limiting area 3311 along the X-axis towards the joint direction. This allows the wire 200, which is clamped and fixed on the wire pressing groove 3412 and the groove 311, to be conveyed and compressed towards the joint direction. In particular, during the melting process of the wire joint 201, the push spring 36 provides a continuous force, which can subject the molten wire to continuous compression, thus making the wire welding more complete and robust. It should also be noted that the force provided by the push spring 36 is greater than the frictional force of the wire groove 23 on the right side of the wire, thus ensuring that the right side of the wire slides in the wire groove 23. At the same time, the frictional force provided by the wire groove 23 on the left side of the wire ensures that the left side of the wire does not slide, thereby achieving compression at the wire joint 201.

[0080] Specifically, in combination Figure 8It can be seen that the contact rod 353 can contact and press the deflection base plate 332 to deflect downward; the spring 105 is used to provide the reset power after deflection and to keep the convex tooth 3321 blocking the bottom of the sliding shell 31. In this figure, the deflection base plate 332 is provided with a window 3312 to allow the convex tooth 3321 to protrude upward for easy blocking.

Any modifications and improvements made by those skilled in the art to the technical solutions of this application without departing from the spirit of this application should fall within the protection scope defined by the claims of this application.
