Description

Technical Field

[0001] This invention relates to the field of printer panel technology, specifically to a 3D printer control panel connection device. Background Technology

[0002] A 3D printer, also known as a three-dimensional printer (3DP), is a type of additive manufacturing technology, or rapid prototyping technology. It uses a digital model file as a basis and employs special waxes, powdered metals, or plastics as adhesive materials to create three-dimensional objects by printing layers of these materials. Currently, 3D printers are used to manufacture products. The control panel of a 3D printer is used to operate the printer, starting and stopping it, and controlling the print head. It is a touch-screen display for operation.

[0003] The panel of a 3D printer is connected to the printer via a power cord. The panel is attached to the printer. Traditional 3D printer panels are usually fixed to the printer and are inconvenient to disassemble. Some panels are detachably connected to the printer via clips. This clip design is prone to damage when the panel is frequently plugged in, making it impossible to fix the panel in place. In addition, the clip design requires a lot of force to disassemble, which affects the operator's ability to hold the panel. Some 3D printers use magnetic attachment for the panel, which is convenient to disassemble. However, when using non-permanent magnets, the magnets are prone to demagnetization, affecting the connection between the panel and the 3D printer. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a 3D printer operation panel connection device.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a 3D printer operation panel connection device, including a printer, the printer including a base, a movable printing platform at the upper end of the base, a movable guide rail on one side of the base and a movable print head on the guide rail, a connection mechanism is installed on one side of the base, the connection mechanism is equipped with an operable panel, and a power cord is connected between the panel and the base.

[0006] The connecting mechanism is equipped with a magnetic mechanism for generating magnetic force, which is connected to a suction mechanism for holding the panel. The connecting mechanism is also equipped with a mounting mechanism for fixing the panel, which is connected to the suction mechanism. The lower end of the connecting mechanism is provided with an exhaust mechanism for internal exhaust and heat dissipation, which is connected to the suction mechanism.

[0007] Specifically, the connecting mechanism includes a connecting shell, which is fixed to one side of the base. A sliding seat is slidably installed on the connecting shell.

An electrode block located to the right of the negative terminal of the power source is horizontally slidably connected to the connecting shell. The electrode block is fixedly connected to the other end of the coil. A first spring is fixed between the electrode block and the connecting shell. A long rod horizontally aligned with the electrode block is fixed to the left end of the sliding seat. A negative electrode plate located on one side of the electrode block is fixed to the negative terminal of the power source.

[0009] Specifically, the suction mechanism includes a metal screw, the left end of which is rotatably connected to the right end of the iron block. A ball bearing sleeve is fixed inside the left side of the sliding seat, and the ball bearing sleeve is threadedly connected to the metal screw. The right end of the metal screw is inserted through the interior of the sliding seat. A fixing sleeve is fixed to the outer wall of the left end of the metal screw, and at least two heat dissipation fan blades are fixed to the outer surface of the fixing sleeve. The right end of the metal screw has a T-shaped cross-section.

[0010] Specifically, the mounting mechanism includes a metal block, which is fixed inside the right side of the sliding seat and flush with the right end of the metal lead screw. The upper right end of the sliding seat has a mounting groove, and the mounting seat is vertically inserted into the mounting groove to support the panel. The right side of the metal block has a slot, and a metal sliding block is horizontally slidably connected to the lower left side of the mounting seat. A second spring is fixed between the metal sliding block and the mounting seat. A locking block flush with the slot is fixed to the left side of the metal sliding block, and the locking block is vertically inserted into the mounting groove. The panel is tilted and positioned at the upper end of the mounting seat.

[0011] Specifically, the exhaust mechanism includes a heat dissipation mesh, a heat dissipation vent is provided through the lower end of the connecting shell, the heat dissipation mesh is fixed at the upper end of the heat dissipation vent and is located directly below the heat dissipation fan blades, a roller located at the lower end of the heat dissipation mesh is rotatably connected inside the heat dissipation vent, four sliding rods are slidably connected to the roller, and a brush that is not in contact with the lower surface of the heat dissipation mesh in the initial state is fixedly connected to the lower end of the sliding rod, the roller is provided with a movable groove, the sliding rod is slidably connected inside the movable groove, and the sliding rod has an I-shaped structure.

[0012] Specifically, the exhaust mechanism also includes a reciprocating lead screw, which is internally threaded to the drum. The reciprocating lead screw is rotatably connected to the heat dissipation port and is arranged laterally. The right end of the reciprocating lead screw passes through the inner wall of the connecting shell. A belt is connected to the outer surface of the fixed sleeve at the right end of the reciprocating lead screw. The distance between the inner surfaces of the belt is greater than the diameter of the long rod.

[0013] The beneficial effects of this invention are:

[0014] (1) The 3D printer operation panel connection device of the present invention drives the magnetic mechanism to generate magnetic force by sliding the connection mechanism, magnetizing the attraction mechanism, attracting the mounting mechanism, and locking the panel, so that the magnetic force is generated only when the panel needs to be fixed, avoiding the waste of power. That is, by sliding the sliding seat to the outside of the connection shell, the panel is moved to the left and adjusted to a suitable position for viewing and operation. At this time, the electrode block is separated from the negative electrode plate, the coil is not energized and no magnetic force is generated. The panel can be moved up to disengage the mounting seat from the sliding seat, and the panel can be disassembled. The panel can be held by hand to operate the printer. By pushing the sliding seat into the connection shell, the long rod is moved to the left until the left end of the long rod contacts the electrode block, pushing the electrode block to the left to compress the first spring until the left end of the electrode block contacts the negative electrode plate. At this time, the power supply, coil, electrode block and negative electrode plate form a closed circuit, energizing the coil and generating magnetic force in the iron block.

[0015] (2) In the 3D printer operation panel connection device of the present invention, after the magnetic mechanism slides out of the connecting mechanism, the magnetic mechanism is automatically de-energized and the magnetism disappears. At this time, the connecting mechanism can be moved to adjust the position of the panel for easy viewing and operation. That is, the panel is supported by inserting the mounting base into the mounting groove of the sliding base. When the sliding base slides into the connecting shell and the long rod moves to push the electrode block to contact the negative electrode plate, the coil is energized, the iron block generates magnetism, and the metal wire rod is magnetized. At this time, the sliding base continues to slide into the connecting shell until the metal block contacts the right end of the metal wire rod. Under the magnetic force of the magnetized metal wire rod, the magnetized metal block is attracted to the metal wire rod. The metal block is held in place and magnetized, causing the sliding seat to adhere to the inside of the connecting shell, thus fixing the panel. Under the magnetic force of the magnetized metal block, the metal sliding block is pulled to the left, stretching the second spring and causing the locking block to slide into the slot, limiting the metal sliding block and the mounting seat, preventing the mounting seat from moving upward, thereby limiting the panel and preventing the panel from loosening. When the operator manually slides the sliding seat out, the long rod is disengaged from the electrode block. At this time, the coil is de-energized, the iron block no longer generates magnetic force, and loses its magnetic effect. The second spring causes the locking block to disengage from the slot, at which point the panel can be moved upward, allowing the mounting seat to disengage from the sliding seat, and the panel can be disassembled and operated by hand.

[0016] (3) The 3D printer operation panel connection device of the present invention drives the heat dissipation fan blades to rotate during the sliding in and out process, so as to dissipate heat inside the connection mechanism, protect the magnetic mechanism and the suction mechanism, so that the magnetic mechanism and the suction mechanism can be used multiple times, and prepare for the fixing and movement of the panel. That is, the heat dissipation fan blades rotate under the action of the metal screw, agitate the airflow inside the connection shell, so that heat flows from the inside of the heat dissipation mesh and exchanges heat with the outside air through the heat dissipation port, so as to cool down the inside of the connection shell. When the sliding seat slides in and out of the connection shell, it drives the metal screw to rotate, drives the fixed sleeve to rotate, and under the action of the belt, the reciprocating screw rotates together, thereby driving the roller and brush to rotate. Under the action of centrifugal force, the slide rod slides out of the roller a certain distance until the brush contacts the lower surface of the heat dissipation mesh. Under the action of the brush, the dust on the lower surface of the heat dissipation mesh is cleaned to ensure the ventilation effect of the heat dissipation mesh. Under the action of the heat dissipation fan blades, the air flows and exchanges heat between the heat dissipation mesh, and during the rotation of the roller and brush, the dust is quickly thrown out of the heat dissipation port.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-7 As shown, the present invention provides an operation panel connection device for a 3D printer, including a printer 1. The printer 1 includes a base 101, a movable printing platform 102 at the upper end of the base 101, a movable guide rail 103 on one side of the base 101, and a movable print head 104 on the guide rail 103. A connection mechanism 2 is installed on one side of the base 101, and an operable panel 3 is installed on the connection mechanism 2. A power cord 301 is connected between the panel 3 and the base 101. The 3D printer 1 is a prior art technology, in which material is sprayed from the print head 104 and received by the printing platform 102 for printing. The printer 1 is operated by the control panel 3.

[0028] The connecting mechanism 2 is equipped with a magnetic mechanism 4 for generating magnetic force. The magnetic mechanism 4 is connected to a suction mechanism 6 for holding the panel 3. The connecting mechanism 2 is also equipped with a mounting mechanism 5 for fixing the panel 3. The mounting mechanism 5 is connected to the suction mechanism 6. The lower end of the connecting mechanism 2 is provided with an exhaust mechanism 7 for internal exhaust and heat dissipation. The exhaust mechanism 7 is connected to the suction mechanism 6. The magnetic force generated by the magnetic mechanism 4 holds the connecting mechanism 2, supports the panel 3, and fixes the panel 3 to one side of the base 101 for connection.

[0029] Specifically, the connecting mechanism 2 includes a connecting shell 21, which is fixed to one side of the base 101. A sliding seat 22 is slidably installed on the connecting shell 21. A mounting seat 302 is slidably inserted into the upper right side of the sliding seat 22. The lower end of the panel 3 is fixedly connected to the upper end of the mounting seat 302. A slider 24 is fixedly connected to the lower end of the sliding seat 22. A limiting groove 25 is opened at the lower right side of the connecting shell 21. The slider 24 is slidably connected inside the limiting groove 25. A baffle 23 is fixed on the upper surface of the connecting shell 21 to limit the movement distance of the panel 3. In use, personnel can slide in and out of the sliding seat 22 to move the panel 3 to the left and adjust its position until it is in a suitable position for personnel to view and operate the panel 3. The slider 24 slides inside the limiting groove 25, limiting the sliding seat 22, so that the sliding seat 22 can slide in and out of the connecting shell 21 to adjust its position.

[0030] Specifically, the magnetic mechanism 4 includes an iron block 42, the left end of which is fixed to the inner wall of the connecting shell 21 and is horizontally positioned. A coil 43 is inserted into the outside of the iron block 42. A power source 41 is fixed to the lower inner wall of the connecting shell 21. The end of the coil 43 is electrically connected to the positive terminal of the power source 41. An electrode block 45 located to the right of the negative terminal of the power source 41 is horizontally slidably connected to the connecting shell 21. The electrode block 45 is fixedly connected to the other end of the coil 43. A first spring 47 is fixed between the electrode block 45 and the connecting shell 21. A long rod 46 aligned horizontally with the electrode block 45 is fixed to the left end of the sliding seat 22. A negative electrode plate 44 located on one side of the electrode block 45 is fixed to the negative terminal of the power source 41. When the sliding seat 22... Sliding into the connecting shell 21, the long rod 46 moves to the left until the left end of the long rod 46 contacts the electrode block 45, pushing the electrode block 45 to the left to compress the first spring 47 until the left end of the electrode block 45 contacts the negative electrode plate 44. At this time, the power supply 41, coil 43, electrode block 45, and negative electrode plate 44 form a closed circuit, energizing the coil 43 and causing the iron block 42 to generate magnetic force, similar to an electromagnet structure. When the sliding seat 22 slides to the left, driving the long rod 46 to the left, under the elastic force of the first spring 47, it pushes the electrode block 45 to the right to disengage from the negative electrode plate 44. At this time, the circuit is broken, the coil 43 is de-energized, and the magnetic force of the iron block 42 disappears, thus controlling the generation and disappearance of the magnetic force of the magnetic mechanism 4.

[0031] Specifically, the suction mechanism 6 includes a metal screw 61, the left end of which is rotatably connected to the right end of the iron block 42. A ball bearing sleeve 63 is fixed inside the left side of the sliding seat 22, and the ball bearing sleeve 63 is threadedly connected to the metal screw 61. The right end of the metal screw 61 is inserted through the interior of the sliding seat 22. A fixing sleeve 64 is fixed to the outer wall of the left end of the metal screw 61, and at least two heat dissipation fan blades 62 are fixed to the outer surface of the fixing sleeve 64. The right end of the metal screw 61 has a T-shaped cross-section. The mechanism works as the sliding seat 22 slides in and out. During the connection process of the housing 21, the ball sleeve 63 is moved. Under the action of the ball sleeve 63, the metal screw 61 is driven to rotate at the right end of the iron block 42, which drives the heat dissipation fan blades 62 on the outer wall of the fixed sleeve 64 to rotate together, stirring the airflow inside the connecting housing 21, accelerating the exchange of heat with the outside air, cooling the inside of the connecting housing 21, protecting the coil 43, the metal screw 61 and other structures. After the coil 43 is energized and the iron block 42 generates magnetic force, the metal screw 61 connected to the iron block 42 is magnetized, and the magnetic force generated by the iron block 42 is large enough.

[0032] Specifically, the mounting mechanism 5 includes a metal block 52, which is fixed inside the right side of the sliding seat 22 and flush with the right end of the metal screw 61. A mounting groove 51 is provided on the upper right side of the sliding seat 22. The mounting seat 302 is vertically inserted into the mounting groove 51 to support the panel 3. A slot 55 is provided on the right side of the metal block 52. A metal sliding block 53 is horizontally slidably connected to the lower left side of the mounting seat 302. A second spring 54 is fixed between the metal sliding block 53 and the mounting seat 302. A locking block 56, flush with the slot 55, is fixed to the left side of the metal sliding block 53. The locking block 56 is vertically inserted into the mounting groove 51. The panel 3 is tilted at the upper end of the mounting seat 302. The mounting seat 302 is inserted into the mounting groove 51 of the sliding seat 22 to support the panel 3. When the sliding seat 22 slides into the connecting shell 21 and the long rod 46 moves, it pushes the electrode block 45 to contact the negative electrode plate 44, energizing the coil 43. The iron block 42 generates magnetic force, and the metal screw 61 is magnetized. At this time, the sliding seat 22 continues to slide into the connecting shell 21 until the metal block 52 contacts the right end of the metal screw 61. Under the magnetic force of the magnetized metal screw 61, the metal block 52 is attracted and magnetized, so that the sliding seat 22 is attracted inside the connecting shell 21, fixing the panel 3. Under the magnetic force of the magnetized metal block 52, the metal sliding block 53 is pulled to the left, stretching the second spring 54, so that the locking block 56 slides into the slot 55, limiting the metal sliding block 53 and the mounting seat 302, preventing the mounting seat 302 from moving upward, thereby limiting the panel 3 and preventing the panel 3 from loosening. When the operator manually slides the sliding seat 22 out, the long rod 46 is separated from the electrode block 45. At this time, the coil 43 is de-energized, the iron block 42 no longer generates magnetic force and loses its magnetic effect. The second spring 54 makes the locking block 56 disengage from the slot 55. At this time, the panel 3 can be moved upward, so that the mounting seat 302 is separated from the sliding seat 22, and the panel 3 can be disassembled. The panel 3 can be operated by hand.

[0033] Specifically, the exhaust mechanism 7 includes a heat dissipation mesh 71, a heat dissipation vent 77 extending through the lower end of the connecting shell 21, the heat dissipation mesh 71 fixed above the heat dissipation vent 77 and located directly below the cooling fan blades 62, a roller 73 rotatably connected inside the heat dissipation vent 77 and located at the lower end of the heat dissipation mesh 71, four sliding rods 74 slidably connected to the roller 73, and a brush 75 initially not in contact with the lower surface of the heat dissipation mesh 71 fixedly connected to the lower end of the sliding rods 74, the roller 73 having a movable groove 78, the sliding rods 74 slidably connected inside the movable groove 78, the sliding rods 74 having an I-shaped structure; the cooling fan blades 62 rotate under the action of the metal screw 61, agitating the airflow inside the connecting shell 21, causing heat to flow from inside the heat dissipation mesh 71 through the heat dissipation vent 77. 7. Heat is exchanged with the outside air, cooling the inside of the connecting shell 21. As the sliding seat 22 slides in and out of the connecting shell 21, it drives the metal screw 61 to rotate, which in turn drives the fixed sleeve 64 to rotate. Under the action of the belt 72, the reciprocating screw 76 rotates together, thereby driving the roller 73 and brush 75 to rotate. Under the action of centrifugal force, the sliding rod 74 slides out of the roller 73 a certain distance until the brush 75 contacts the lower surface of the heat dissipation mesh 71. Under the action of the brush 75, the dust on the lower surface of the heat dissipation mesh 71 is cleaned, ensuring the ventilation effect of the heat dissipation mesh 71. Under the action of the heat dissipation fan blades 62, the air flows and exchanges heat between the heat dissipation mesh 71. During the rotation of the roller 73 and brush 75, the dust is quickly thrown out of the heat dissipation port 77.

[0034] Specifically, the exhaust mechanism 7 also includes a reciprocating screw 76, which is internally threaded to the roller 73. The reciprocating screw 76 is rotatably connected to the heat dissipation port 77 and is arranged laterally. The right end of the reciprocating screw 76 passes through the inner wall of the connecting shell 21. The right end of the reciprocating screw 76 is connected to the outer surface of the fixed sleeve 64 by a belt 72. The distance between the inner surfaces of the belt 72 is greater than the diameter of the long rod 46 in order to realize the rotation of the roller 73.

[0035] When using this invention, firstly, the operator slides the sliding seat 22 to the outside of the connecting shell 21, so that the panel 3 moves to the left and is adjusted to a suitable position for viewing and operation. At this time, the electrode block 45 is separated from the negative electrode plate 44, the coil 43 is not energized and does not generate magnetic force, so the panel 3 can be moved up to make the mounting base 302 disengage from the sliding seat 22. The panel 3 can be disassembled and the printer 1 can be operated by holding the panel 3.

[0036] Then, when the operation is complete, the sliding seat 22 can be pushed into the connecting shell 21, causing the long rod 46 to move to the left until the left end of the long rod 46 contacts the electrode block 45, pushing the electrode block 45 to the left to compress the first spring 47, until the left end of the electrode block 45 contacts the negative electrode plate 44. At this time, the power supply 41, coil 43, electrode block 45, and negative electrode plate 44 form a closed circuit, energizing the coil 43 and causing the iron block 42 to generate magnetic force. During the sliding seat 22 sliding in and out of the connecting shell 21, it drives the ball sleeve 63 to move. Under the action of the ball sleeve 63, the metal screw 61 is driven to rotate at the right end of the iron block 42, causing the heat dissipation fan blades 62 on the outer wall of the fixed sleeve 64 to rotate together, stirring the airflow inside the connecting shell 21. Accelerating heat exchange with the outside air cools the inside of the connecting shell 21, protecting structures such as the coil 43 and the metal screw 61. After the coil 43 is energized, the iron block 42 generates magnetic force, which magnetizes the metal screw 61 connected to the iron block 42, attracting the metal block 52 and magnetizing the metal block 52. This causes the sliding seat 22 to be attracted inside the connecting shell 21, fixing the panel 3. Under the action of the magnetized magnetic force of the metal block 52, the metal sliding block 53 is pulled to the left, stretching the second spring 54 and causing the locking block 56 to slide into the locking groove 55, limiting the metal sliding block 53 and the mounting seat 302, preventing the mounting seat 302 from moving upward, thereby limiting the panel 3 and preventing the panel 3 from loosening. This is used for the connection between the panel and the printer.

[0037] Finally, the cooling fan blades 62 rotate under the action of the metal screw 61, stirring the airflow inside the connecting shell 21, so that heat flows from inside the heat dissipation mesh 71 and exchanges heat with the outside air through the heat dissipation port 77, thus cooling the inside of the connecting shell 21. When the sliding seat 22 slides in and out of the connecting shell 21, it drives the metal screw 61 to rotate, which drives the fixed sleeve 64 to rotate. Under the action of the belt 72, the reciprocating screw 76 rotates together, thereby driving the roller 73 and the brush 75 to rotate. Under the action of centrifugal force, the sliding rod 74 slides out of the roller 73 for a distance until the brush 75 contacts the lower surface of the heat dissipation mesh 71. Under the action of the brush 75, the dust on the lower surface of the heat dissipation mesh 71 is cleaned, ensuring the ventilation effect of the heat dissipation mesh 71.
