[0001] The utility model belongs to the technical field of temperature detection, and particularly relates to a printer temperature detection device. Background Art

[0002] With the continuous development of technology, 3D printing technology has become increasingly mature and has been widely used and developed. From ordinary consumer goods to aerospace, and then to human life, 3D printing can do almost everything.

[0003] The print head of a 3D printer is a key part of the 3D printer. During the printing process, if the temperature of the print head is too high, it is easily damaged, affecting the service life of the printer. Most of the existing temperature detections can only detect the body temperature. The temperature of the print head is much higher than the body temperature, so the problem of the print head cannot be accurately detected, and the print head is easily damaged at high temperature. Since the print head needs to move three-dimensionally, it is impossible to effectively detect the temperature of the print head.

[0004] Therefore, a printer temperature detection device is proposed. Content of the Utility Model

Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0024] An embodiment of the present utility model provides a printer temperature detection device, as Figures 1-5As shown in the figure, it includes a printer cabin 1. Inside the printer cabin 1, there is a print head 2. And on one side inner wall of the printer cabin 1, there is a fixed platform 3 fixedly connected by bolts. On the outer wall of one side of the fixed platform 3, there is a controller fixedly connected by screws. At the central position on the top of the fixed platform 3, there is a first servo motor 4 fixedly connected by bolts. The first servo motor 4 is fixedly connected with a ball screw 5 through the output end on its one side. On the outer wall of one side of the fixed platform 3, near the side of the ball screw 5, there is a through groove. The nut seat on the ball screw 5 is fixedly connected with a lifting cover 6 by screws. The lifting cover 6 is a hollow cuboid structure with one side open. On the top of the lifting cover 6, there is a cross plate 7 fixedly connected by bolts. On the outer wall of one side of the cross plate 7, there is an infrared receiver 8 embedded. On the outer wall of one side of the lifting cover 6, there is a second servo motor 9 fixedly connected by bolts. The second servo motor 9 is fixedly connected with a wire reel 10 through the output end on its one side. On the outer wall of the wire reel 10, there is a wire harness 11 wound around. One end of the wire harness 11 is provided with a detection head 12. On the outer wall of one side of the detection head 12, near the side of the print head 2, there is a temperature sensor 13 embedded. On the outer wall of the other side of the detection head 12, there is an infrared emitter 14 embedded. On the inner wall of one side of the lifting cover 6, near the upper side of the wire reel 10, there is a support plate 15 fixedly connected by bolts. On the top of the support plate 15, there is a sleeve 16 fixedly connected by bolts. At the bottom inside the sleeve 16, there is a pressure sensor 17. On the top of the pressure sensor 17, there is a spring 18. At the top of the spring 18, there is a support rod 19. The top of the support rod 19 is fixedly connected with a detection wheel bracket 20 by bolts. On the inner side wall of the detection wheel bracket 20, there is a detection wheel 21 rotatably connected. The cross sections of the wire reel 10 and the detection wheel 21 are both "I" - shaped structures.

[0025] It should be noted that since most of the existing temperature detections of 3D printers can only detect the body temperature, and the temperature of the print head is much higher than the body temperature, thus the problem that the print head cannot be accurately detected easily occurs, and the print head is likely to be damaged at high temperatures. Because the print head needs three - dimensional movement, it is impossible to effectively detect the temperature of the print head. In this embodiment, the temperature sensor 13 can perform real - time temperature detection on the print head 2, avoiding the problem that the print head cannot be detected when it is in a three - dimensional movement state. And the detection wheel 21 is used to detect the pressure change brought by the wire harness 11 and control the tension or relaxation state of the wire harness 11, so as to ensure that the wire harness 11 is in a straight state, and further avoid the problem that the wire harness 11 is slack and contacts the workpiece to cause damage.

[0026] Specifically, in this embodiment, the solution mainly includes an infrared receiver 8, a wire take-up reel 10, a temperature sensor 13, an infrared emitter 14, and a detection wheel 21. During use, the detection head 12 is adhesively fixed to the outer wall of the print head 2 through a high-temperature resistant adhesive. The temperature sensor 13 is closely attached to the outer wall of the print head 2. The first servo motor 4 is controlled to drive the ball screw 5 to rotate through the output end on one side thereof. The lifting cover 6 on the ball screw 5 moves up and down on the fixed platform 3, and the infrared receiver 8 and the infrared emitter 14 are adjusted to the same horizontal plane. The second servo motor 9 is controlled to drive the wire take-up reel 10 to rotate through the output end on one side thereof. The wire take-up reel 10 winds up the wire harness 11 and keeps the wire harness 11 in a tensioned state. At this time, the wire harness 11 presses down on the detection wheel 21. After being pressed, the detection wheel 21 drives the support rod 19 and the detection wheel bracket 20 to move downward. The support rod 19 presses the spring 18, and the spring 18 is compressed under force. The pressure sensor 17 detects the resilience of the spring 18. After the installation and adjustment of the temperature detection device are completed, the temperature sensor 13 detects the temperature of the print head 2 in real time. When the print head 2 performs three-dimensional mobile printing, the detection wheel 21 is used to detect the pressure change brought by the wire harness 11 to control the tensioned or relaxed state of the wire harness 11, so as to ensure that the wire harness 11 is in a straight state, and further avoid the problem that the wire harness 11 is slack and contacts the workpiece and causes damage. Specifically, when the print head 2 moves up and down, the print head 2 drives the wire harness 11 to move in the vertical direction, and the pressing force of the wire harness 11 on the detection wheel 21 becomes larger or smaller. When the pressure detected by the pressure sensor 17 becomes smaller, the controller controls the first servo motor 4 to work, and the lifting cover 6 on the ball screw 5 moves upward. The infrared receiver 8 and the infrared emitter 14 are used to receive infrared rays to determine the height of the temperature sensor 13, so that the wire harness 11 is always in a taut state.

[0027] In a further preferred embodiment of the present utility model, as Figure 1 shown, the print head 2 and the detection head 12 are adhesively fixed through an adhesive, and the temperature sensor 13 is closely attached to the outer wall of the print head 2.

[0028] In this embodiment, the connection between the detection head 12 and the print head 2 is realized through an adhesive, and then the temperature of the print head 2 is detected by using the temperature sensor 13.

[0029] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 5 shown, a plurality of infrared receivers 8 are provided, and the plurality of infrared receivers 8 are equidistantly arranged on the outer wall of one side of the cross plate 7. The infrared receiver 8 and the infrared emitter 14 are on the same horizontal plane.

[0030] In this embodiment, the infrared receiver 8 and the infrared emitter 14 on the same horizontal plane can set the initial position state, providing initial information for subsequent automatic adjustment, and several infrared receivers 8 can fully receive the infrared ray information emitted by the infrared emitter 14.
