DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.
[0027] As Figures 1 to 6 shown, the utility model provides a kind of novel photocuring 3D printer automatic feeding device, specifically, including printer main body 1 and feeding mechanism;Resin tank 2 is provided at the top of the printer main body 1, for holding resin consumables;The feeding mechanism is set to one side of printer main body 1, for automatically adding resin consumables in resin tank 2.
[0028] Specifically, the feeding mechanism comprises a telescopic driving device 3, a telescopic arm 4, a feeding head mounting seat 5 and a feeding head 6; wherein the telescopic driving device 3 adopts an electric telescopic rod, the output end of which is connected with one end of the telescopic arm 4; the other end of the telescopic arm 4 is connected with the feeding head mounting seat 5; further optimization, the feeding head 6 is detachably mounted on the feeding head mounting seat 5.
[0029] Further, the telescopic arm 4 adopts a self-adaptive telescopic design, which can automatically adjust the length according to different positions of the resin tank 2; specifically, as shown in Figure 3 and Figure 4 , the telescopic arm 4 comprises a fixed segment 401, a movable segment 402 and a telescopic adjusting mechanism 403 connecting the fixed segment 401 and the movable segment 402; further, the fixed segment 401 is connected with the output end of the telescopic driving device 3; further, the telescopic adjusting mechanism 403 comprises a spring 4031 and a guide rod 4032 arranged inside the fixed segment 401; the movable segment 402 is slidably connected with the fixed segment 401 through the guide rod 4032; one end of the spring 4031 is connected with the fixed segment 401, and the other end is connected with the movable segment 402; when the position of the resin tank 2 is different, the movable segment 402 can slide along the guide rod 4032 under the action of the spring 4031, thereby adaptively adjusting the length of the feeding arm 4.
[0030] Further, the feeding head mounting seat 5 and the feeding head 6 are connected by magnetic attraction; specifically, as shown in Figure 3 and Figure 4 , the feeding head mounting seat 5 is provided with a magnetic attraction component 501, and the bottom of the feeding head 6 is provided with a magnetic material layer 601 matched with the magnetic attraction component 501; through the adsorption action of the magnetic attraction component 501 and the magnetic material layer 601, the feeding head 6 and the feeding head mounting seat 5 are quickly connected and detached; in addition, the feeding head mounting seat 5 is also provided with a positioning pin 502 and a positioning hole 503, and correspondingly, the bottom of the feeding head 6 is provided with a positioning groove 603 matched with the positioning pin 502; through the cooperation of the positioning pin 502 and the positioning groove 603, the correct position of the feeding head 6 can be ensured during installation.
[0031] Further optimization, in order to control the adding amount and speed of the resin consumables, therefore, a flow regulating valve 602 is arranged on the feeding head 6 for controlling the flow of the resin consumables; during use, the user can adjust the opening of the flow regulating valve 602 according to the actual demand, thereby adjusting the adding speed of the resin consumables.
[0032] Of course, during the working process of the photocuring 3D printer, it is necessary to know the remaining amount of the resin consumables for adding; in order to monitor the remaining amount of the resin consumables in the resin tank 2 in real time, the utility model also arranges a sensor assembly 7 on the telescopic arm 4; specifically, as shown inFigure 4 As shown in the drawings, the sensor assembly 7 includes a distance sensor and a controller arranged on the telescopic arm 4; the distance sensor is used to detect the liquid level of the resin consumable in the resin tank 2 and send a detection signal to the controller; the controller judges the remaining amount of the resin consumable according to the received detection signal and sends an alarm signal when the remaining amount is insufficient, or directly controls the automatic feeding device to automatically feed.
[0033] In order to improve the stability and safety of the device, the utility model also sets up safe locking mechanism 8 on telescopic arm 4, as shown in the drawings, Figure 6 The safe locking mechanism 8 includes locking bolts and locking blocks arranged on the telescopic arm 4; after the telescopic arm 4 is adjusted to the appropriate length, the user can fix the locking blocks with the telescopic arm 4 by tightening the locking bolts, so as to lock the position of the telescopic arm 4.
[0034] Further, the telescopic arm 4 is further optimized; specifically, the utility model improves the structure of the self-adaptive telescopic feeding arm to improve its self-adaptive ability and stability.
[0035] As shown in the drawings, Figure 5 And Figure 6 As shown in the drawings, the improved telescopic arm 4 is also the same as the above structure, including a fixed section 401, a movable section 402 and a telescopic adjusting mechanism 403 connecting the fixed section 401 and the movable section 402; different from the telescopic arm 4 of the above embodiment is that: the telescopic adjusting mechanism 403 includes a spring 4031 and a guide rod 4032, and a limiting block and a buffer pad are additionally provided; the limiting block is arranged at both ends of the guide rod 4032 and is used to limit the sliding range of the movable section 402; the buffer pad is arranged between the movable section 402 and the fixed section 401, and in the improved structure, the addition of the limiting block and the buffer pad further improves the stability and durability of the device.
[0036] Specifically, in the use process, the limiting block, as the physical limit of the sliding of the movable section 402, ensures that the feeding arm will not exceed the predetermined range when adjusting the length, thereby avoiding the structural damage or functional failure caused by excessive telescoping; these limiting blocks are usually made of wear-resistant and high-strength materials to ensure their long-term reliability. Secondly, the buffer pad is arranged on the contact surface between the movable section 402 and the fixed section 401, which plays a role in reducing impact, reducing noise and protecting the telescopic adjusting mechanism; when the movable section 402 slides along the guide rod 4032 under the action of the spring 4031, the buffer pad can absorb part of the kinetic energy, reducing the impact force caused by rapid movement, thereby prolonging the service life of the feeding arm; at the same time, the buffer pad can also effectively reduce the noise generated during telescoping, improving the user's experience.
[0037] In addition to improving the structure of the telescopic arm 4, the utility model also optimizes in other aspects;For example, in order to further improve the accuracy and stability of feeding, the flow regulating valve 602 is designed finely;The flow regulating valve adopts advanced flow control technology, which can realize the accurate adjustment of resin consumable flow;The user only needs to rotate the adjusting knob slightly, and can adjust the adding speed of resin consumables according to the needs, so as to ensure that the resin supply in the printing process is stable and accurate.
[0038] In addition, the utility model also upgrades the sensor assembly 7;The new sensor assembly adopts a more sensitive and accurate distance sensor, which can monitor the liquid level of resin consumables in the resin tank 2 in real time and transmit data to the controller in real time;The controller analyzes and processes the received data, and when the remaining amount of resin consumables is insufficient, an alarm signal is automatically sent, and the automatic feeding device is controlled to automatically add resin consumables;This improvement not only improves the intelligent level of the device, but also greatly reduces the risk of printing interruption caused by the depletion of resin, which will lead to poor product quality and increase the rate of defective products.
[0039] Further, in the safety locking mechanism 8, the utility model also optimizes accordingly;Specifically, the optimized safety locking mechanism adopts a more reliable locking mechanism that is easier to operate, so that the user can easily and quickly lock the position after adjusting the length of the telescopic arm;This improvement not only improves the convenience of the device, but also further enhances its stability and safety.
[0040] The novel photocuring 3D printer automatic feeding device of the utility model has been significantly improved in terms of adaptability, stability, accuracy and intelligent level;These improvements not only improve the performance and user experience of the device, but also lay a solid foundation for its application in a wider field.
