A printed adhesive planar assembly

Abstract

This invention discloses a printing and bonding planar assembly, including a printing table, a rejection device disposed on one side of the printing table, and a laser sensor on the other side. The printing table includes an adjustment platform, a first lead screw, and a support platform. A first lead screw sleeve is fitted around the outer side of the first lead screw. The adjustment platform is movably connected to the first lead screw through the first lead screw sleeve. This invention specifically relates to the field of 3D printers. Because of the rejection device, this printing and bonding planar assembly, when the model is printed onto the adjustment platform and the molten printing material passes through the mesh blind holes, accumulates and adheres under gravity, causing non-printed parts below the mesh blind holes to stick together, the rejection device removes the printing material below the adjustment platform by moving the rejection blade along the lead screw axis through the second lead screw sleeve. This releases the adhesion of the printing material below the mesh blind holes, solving the problem of the model being difficult to remove due to adhesion.

Description

Technical Field

[0001] This invention belongs to the field of 3D printers, specifically relating to the printing of adhesive planar components. Background Technology

[0002] Patent CN210062038U discloses a printing and bonding plane assembly for a 3D printer. The beneficial effects of this patent are as follows:

[0003] 1. By setting a mesh blind hole structure on the printing leveling platform, the printing material can enter the mesh blind hole when it is initially molten with the printing leveling platform. When the molten printing material enters the mesh blind hole and cools, it will form an adhesion with the printing adhesive base plate, thereby making the bottom of the printed model fixed to the printing adhesive base plate and facilitating the removal of the printed model after printing.

[0004] 2. Compared with traditional methods, it is more convenient and labor-saving, can be reused, and is easy to clean, offering good economic and social benefits, making it suitable for widespread use. Furthermore, the ball screw mechanism, in conjunction with the printing leveling platform, allows for adjustment of the platform's height, enabling the printing of 3D models of different volumes or sizes.

[0005] However, in actual use, the molten printing material accumulates and sticks together under the influence of gravity after passing through the mesh blind holes. This causes the non-printed parts below the mesh blind holes to stick together, making it impossible to remove the model. At the same time, the molten printing material is also prone to adhering inside the mesh blind holes, which reduces the connection strength between the mesh blind holes and the model, thus damaging the device. Summary of the Invention

[0006] The purpose of this invention is to provide a printed adhesive planar assembly to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a printing and bonding planar assembly, comprising a printing table, a rejection device disposed on one side of the printing table, and a laser sensor on the other side. The printing table includes an adjustment platform, a first lead screw, and a support platform. A first lead screw sleeve is sleeved on the outer side of the first lead screw. The adjustment platform is movably connected to the first lead screw through the first lead screw sleeve. The rejection device includes a base disposed inside the first lead screw sleeve. A second lead screw is connected to one side of the base through a connecting rod. A rejection blade is connected to the outer side of the second lead screw through a second lead screw sleeve.

[0008] Preferably, the device includes a plug-in device disposed on one side of the support platform. The plug-in device includes a socket, a second cylinder disposed on one side of the socket, a lifting cover disposed on the output end of the second cylinder, and a plug-in assembly disposed on one side of the lifting cover. The plug-in assembly is adapted to the adjustment platform.

[0009] Preferably, the insert assembly is provided with an insert rod, the insert rod is engaged with a connecting shaft through a tapered groove, one end of the connecting shaft is connected to a spring through a spring shaft, and the end of the spring shaft away from the connecting shaft is engaged with a screw hole through a screw seat.

[0010] Preferably, the base is hinged to the connecting rod via a third hinge, the connecting rod is hinged to the second lead screw via a first hinge, and the third hinge is hinged to the base via a second hinge.

[0011] Preferably, the base is provided with a first cylinder, and the third hinge is provided with a top groove that is adapted to the output end of the first cylinder.

[0012] Preferably, one end of the insertion rod is provided with an insertion tip.

[0013] Preferably, the socket has a slot inside, and the lifting cover is adapted to the slot.

[0014] Preferably, a first motor is fixedly connected to the bottom of the support platform, and the output end of the first motor is fixedly connected to a first lead screw.

[0015] Preferably, one end of the first hinge is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to a second lead screw.

[0016] Preferably, the blade is configured with a double-edged structure.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] (1) The printing and bonding plane component is equipped with a rejection device. When the printing material in the molten state passes through the mesh blind hole after the model is printed to the adjustment plate, it accumulates and sticks under the action of gravity, causing the non-printing parts below the mesh blind hole to stick together. By first heating the printing table to make the material into a semi-molten state, and then causing the second lead screw sleeve to drive the rejection blade to move along the lead screw axis, the printing material below the adjustment plate can be rejected, the adhesion state of the printing material below the mesh blind hole can be released, and the problem of the model being difficult to remove due to adhesion can be solved.

[0019] (2) The printing and bonding plane component is equipped with a tube assembly. When the molten printing material easily adheres to the inside of the mesh blind hole, causing the mesh blind hole to become blocked, the printing table is heated first to make the material become semi-molten. Then, the second cylinder drives the tube assembly through the adjustment platform to clear the blocked mesh blind hole and solve the problem of reduced connection strength between the mesh blind hole and the model.

[0020] (3) The printing and bonding plane assembly has a spring inside the connecting shaft. When the insert rod moves, the spring can be used to clamp the cone and to dampen the insertion rod. This avoids the problem of vibration when the insert rod clears the mesh blind holes and the vibration is transmitted to the bottom plate, which can damage the device. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-6As shown, the present invention provides the following technical solution: a printing and bonding planar assembly, including a printing table 1, a rejection device 2 disposed on one side of the printing table 1 and a laser sensor 3 disposed on the other side. The printing table 1 includes an adjustment platform 11, a first lead screw 12 and a support platform 14. A first lead screw sleeve 15 is sleeved on the outside of the first lead screw 12. The adjustment platform 11 is movably connected to the first lead screw 12 through the first lead screw sleeve 15. The rejection device 2 includes a base 20 disposed inside the first lead screw sleeve 15. A second lead screw 21 is connected to one side of the base 20 through a connecting rod 28. A rejection blade 23 is connected to the outside of the second lead screw 21 through a second lead screw sleeve 22.

[0030] Example 1:

[0031] Because of the laser sensor 3, when the model is printed to the adjustment plate and the molten printing material passes through the mesh blind holes, it accumulates and sticks under the action of gravity, causing the non-printing parts below the mesh blind holes to stick together. The laser sensor 3 detects the height of the sticking material. If the laser beam of the laser sensor 3 is blocked, the output end of the first cylinder 201 moves into the top groove 271. The third hinge 27 swings after being pushed, moving the connecting rod 28 and the first hinge 25 away from the printing table 1. This causes the second lead screw 21 to rise simultaneously as it moves away from the printing table 1, thus raising the height of the scraper 23. At this time, the second motor 24 drives the second lead screw 21 to rotate, which realizes the purpose of moving the second lead screw sleeve 22 and the scraper 23 along the axial direction of the second lead screw 21, realizing the height adjustment of the scraper 23 and the removal of printing material below the support table 14.

[0032] Furthermore, it includes a tube device 4 disposed on one side of the support platform 14. The tube device 4 includes a socket 42, a second cylinder 45 disposed on one side of the socket 42, a lifting cover 41 disposed on the output end of the second cylinder 45, and a tube assembly 5 disposed on one side of the lifting cover 41. The tube assembly 5 is adapted to the adjustment platform 11.

[0033] Furthermore, the insert assembly 5 is provided with an insert rod 51, which is engaged with a connecting shaft 54 ​​through a tapered groove 53. One end of the connecting shaft 54 ​​is connected to a spring 56 through a spring shaft 55, and the end of the spring shaft 55 away from the connecting shaft 54 ​​is screwed into a screw hole 44 through a screw seat 57.

[0034] Example 2:

[0035] The second cylinder 45 drives the lifting cover 41, which in turn drives the insert assembly 5 to move closer to the support platform 14. At the same time, the first motor 13 drives the first lead screw 12 to move the first lead screw sleeve 15 and the support platform 14 closer to the insert assembly 5, so that the insert tip 52 can pass through the mesh holes to clean the support platform 14. Meanwhile, when the insert assembly 5 acts on the support platform 14, the insert rod 51 can be clamped by the spring 56 when it moves, and the spring 56 can also be used to dampen the vibration of the insert rod 51, so as to avoid the problem of vibration when the insert rod 51 clears the mesh blind holes and the vibration being transmitted to the printing table 1, which could damage the device.

[0036] Furthermore, the base 20 is hinged to the connecting rod 28 via the third hinge 27, the connecting rod 28 is hinged to the second lead screw 21 via the first hinge 25, and the third hinge 27 is hinged to the base 20 via the second hinge 26.

[0037] Furthermore, the base 20 is provided with a first cylinder 201, and the third hinge 27 is provided with a top groove 271 that is adapted to the output end of the first cylinder 201.

[0038] Furthermore, one end of the insertion rod 51 is provided with an insertion tip 52.

[0039] Furthermore, the socket 42 has a slot 43 inside, and the lifting cover 41 is adapted to the slot 43.

[0040] Furthermore, a first motor 13 is fixedly connected to the bottom of the support platform 14, and the output end of the first motor 13 is fixedly connected to the first lead screw 12.

[0041] Furthermore, a second motor 24 is fixedly connected to one end of the first hinge 25, and the output end of the second motor 24 is fixedly connected to the second lead screw 21.

[0042] Furthermore, the blade 23 is configured with a double-edged structure. The double-edged blade 23 can remove the printing material during its reciprocating motion along the second lead screw 21, effectively improving the removal efficiency of the blade 23.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
