[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] Reference Figure 1-Figure 6 A 3D printing device capable of continuous production includes a body 1 and a substrate 2 used in conjunction with a suction machine. A transition cabin 3, a substrate inlet and outlet 4 and a molding chamber 5 are sequentially arranged on the upper end of the body 1. It should be noted that the transition cabin 3 has an independent door, and the door is located at the top of the door. The transition cabin 3 is mainly used to store the substrate 2. The substrate inlet and outlet 4 is arranged on a side of the transition cabin 3 close to the body 1, and is U-shaped. Its height is lower than the height of the substrate in a vertically placed state, and the width of the substrate inlet and outlet 4 is greater than the width of the substrate.

[0032] The machine body 1 is fixedly provided with electric slide rails 6 located in the transition chamber 3, the substrate inlet and outlet 4 and the molding chamber 5. The electric slide rails 6 are arranged at the inner side of the substrate inlet and outlet 4, and the electric slide rails 6 are arranged in two groups.

[0033] It should be added that: the electric slide rail 6 is a prior art and is not the focus of protection of this application document. In some embodiments, the electric slide rail 6 includes two parts: a slide rail and a power source. Preferably, the slide rail is made of metal material and has good strength and straightness. The shape of the track can be linear. The power source is a motor, specifically. Common types of motors are stepper motors and DC motors. The advantage of a stepper motor is that it can accurately control the angle of rotation, thereby achieving high-precision displacement control; the DC motor is relatively low in cost and is widely used in some scenarios where the precision requirements are not extremely high. The transmission methods mainly include belt drive, screw drive and gear drive. Belt drive is relatively quiet and stable, and can achieve long-distance transmission, but the precision is relatively low; screw drive has high precision and can carry large loads, but the speed is relatively slow; gear drive has high efficiency and good precision, but may produce certain noise.

[0034] Based on the setting of the electric slide rail 6, in order to transport the substrate 2 in the transition cabin 3 from the cabin door of the transition cabin 3 and the substrate inlet and outlet 4 to the body 1 through the electric slide rail 6, a limiting part 7 is provided on the electric slide rail 6 for resisting and limiting the substrate 2 and cooperating with the substrate inlet and outlet 4 to flip the substrate 2.

[0035] In a further embodiment, the limiting part 7 includes a wedge block 701 mounted on the electric slide rail 6, and the upper surface of the wedge block 701 is inclined. The inclination direction can refer to Figure 1-Figure 3 .

[0036] The wedge block 701 in this embodiment is the driven part on the electric slide rail 6. The wedge block 701 contacts the slide rail, so that the slider can slide smoothly on the rail and slide on the slide rail after being driven by the power source.

[0037] A contact plate 702 that movably contacts the base plate 2 is slidably mounted on the wedge block 701. The contact plate 702 is composed of two longitudinal plates and a transverse plate. The two longitudinal plates are diagonally arranged at both ends of the transverse plate.

[0038] A return spring 703 is fixedly connected between the inner side of one end of the contact plate 702 away from the substrate 2 and the wedge block 701. The return spring 703 is arranged in multiple groups. The elastic force of the return spring 703 enables the contact plate 702 to be returned when not squeezed.

[0039] A support slider 704 is fixedly disposed on the outer side of the end of the abutment plate 702 away from the substrate 2. Figure 3The support slider 704 is fixed to the corner of the end of the contact plate 702 away from the body 1. The support slider 704 is equipped with a support rod 705. The support rod 705 is tilted, and the tilt direction of the support rod 705 is opposite to the tilt direction of the upper surface of the wedge block 701. The tilt direction can be referred to Figure 2 The two sides of the substrate 2 are linearly clamped by the support rod 705 and the abutment plate 702 to ensure the horizontal movement of the substrate 2 in a vertical state.

[0040] The support rod 705 is provided with a support slot 706 for slidingly fitting the support slider 704, and a support spring 707 is fixedly connected between the support slider 704 and the support slot 706. Through the elastic force of the support spring 707, the support rod 705 is reset when not squeezed.

[0041] Based on the setting of the machine body 1, in order to realize the rapid disassembly and assembly and automatic leveling of the substrate 2 and thereby achieve the purpose of reducing manual intervention, a disassembly and assembly portion 8 for rapid disassembly and assembly and leveling of the substrate 2 in the machine body 1 is provided in the machine body 1.

[0042] A further implementation method is as follows: the disassembly and assembly part 8 includes a mounting plate 801 fixedly mounted on the inner wall of the body 1, a telescopic cylinder 802 fixedly mounted on the mounting plate 801, a bottom plate 803 fixedly connected to the output end of the telescopic cylinder 802, fixing holes 804 are provided on the bottom plate 803 and the base plate 2, a motor 805 fixedly mounted on the inner wall of the body 1, a rotating shaft 806 fixedly connected to the output end of the motor 805, and a fixing plate 807 fixedly sleeved on the rotating shaft 806 for movably interfering with the base plate 2.

[0043] When the rotating shaft 806 is located in the fixing hole 804, the output end of the telescopic cylinder 802 moves upward, so that the fixing plate 807 and the substrate 2 are movably opposed to each other. The abutment and limiting of the fixing plate 807 at the four corresponding corners of the substrate 2 helps to ensure the horizontality of the substrate 2 and helps to reduce the time for manual adjustment of the substrate 2.

[0044] The fixing hole 804 is composed of a circular hole and a rectangular hole intersecting each other. The fixing plate 807 is arranged corresponding to the rectangular hole, and the fixing plate 807 is rotated by the motor 805 so that the fixing plate 807 and the rectangular hole are in a cross-intersecting state. At this time, the substrate 2 cannot be detached from the top, and the bottom end of the substrate 2 is limited by the bottom plate 803 to ensure that the substrate 2 cannot be detached from the bottom. The output end of the telescopic cylinder 802 is extended, and the height position of the fixing plate 807 remains unchanged. The telescopic cylinder 802 drives the substrate 2 to move upward through the bottom plate 803, so that the fixing plate 807 is closely fitted with the substrate 2, which helps to improve the stability of the substrate 2.

[0045] A contact plate 808 is fixedly mounted on the rotating shaft 806 and is in active contact with the bottom plate 803 . It should be noted that the distance between the top surface of the contact plate 808 and the bottom surface of the fixed plate 807 is greater than the sum of the thicknesses of the bottom plate 803 and the base plate 2 .

[0046] It should be noted that the specific models and specifications of the telescopic cylinder 802 and the motor 805 need to be selected and determined according to the actual specifications of the equipment, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0047] The functional principle of the utility model can be explained through the following operation modes:

[0048] The automatic loading process of substrate 2 is as follows:

[0049] Stage 1, feeding stage: the electric slide rail 6 drives the substrate 2 in the transition chamber 3 to move horizontally into the molding chamber 5 through the limiting part 7, that is, the substrate 2 clamped between the support rod 705 and one end of the contact plate 702 moves horizontally under the drive of the electric slide rail 6; when the outer wall of the substrate 2 initially contacts the outer wall of the substrate inlet and outlet 4, the substrate 2 deflects downward under the influence of the top contact of the substrate inlet and outlet 4, and the substrate 2 pulls the contact plate 702 to move toward the machine body 1 and squeezes the reset spring 703; at the same time, the contact plate 702 drives the support rod 705 to move away from the machine body 1, the substrate 2 deflects downward and squeezes the support rod 705 to move downward, so that the support slider 704 stretches the support spring 707. In this process, the substrate 2 is arranged in an inclined manner, but it remains stable under the action of the support rod 705 and the contact plate 702 and will not leave the clamping and positioning state;

[0050] Stage 2, unloading stage: First, after the substrate 2 passes through the substrate inlet and outlet 4, the support rod 705 and the contact plate 702 are reset under the elastic force of the reset spring 703 and the support spring 707, and the substrate 2 is reset under the pushing force generated by the reset of the support rod 705 and the contact plate 702. Secondly, the electric slide rail 6 drives the substrate 2 located in the molding bin 5 to move horizontally in the direction of the transition chamber 3 through the limiter 7, and the other side of the substrate 2 is against the other side of the substrate inlet and outlet 4. Since the inclination direction of the substrate 2 is the same as the inclination direction of the support rod 705 at this stage, the substrate 2 loses the clamping force of the support rod 705, causing the substrate 2 to break away from the clamping of the support rod 705 and the contact plate 702, and then enter the machine body 1 under the action of gravity.

[0051] The process of quick disassembly and leveling of base plate 2 is as follows:

[0052] After the loading of substrate 2 is completed, the rapid installation and leveling process of substrate 2 is as follows: after the unloading stage based on stage 2, substrate 2 falls onto the bottom plate 803. At this time, the telescopic cylinder 802 drives the bottom plate 803 to move vertically downward, and the rotating shaft 806 and the fixed plate 807 enter the fixed hole 804; then, the motor 805 drives the rotating shaft 806 to rotate 90°, and the rotating shaft 806 drives the fixed plate 807 to rotate 90°, so that the fixed plate 807 and the rectangular hole in the fixed hole 804 are in a cross state; finally, the telescopic cylinder 802 drives the bottom plate 803 to move vertically upward, and the bottom plate 803 supports the substrate 2 to move vertically upward. At this time, the upper surface of the substrate 2 and the fixed plate 807 are movably against each other, and the lower surface of the substrate 2 and the top surface of the bottom plate 803 are against each other, thereby ensuring the horizontality and installation process of the substrate 2.

[0053] The quick disassembly process of the substrate 2 is as follows: when the substrate 2 located in the body 1 needs to be disassembled, the motor 805 drives the rotating shaft 806 to rotate 90°, and the rotating shaft 806 drives the fixed plate 807 to rotate 90°, so that the fixed plate 807 and the rectangular hole in the fixing hole 804 are arranged correspondingly up and down, and the telescopic cylinder 802 drives the bottom plate 803 to move vertically upward, and the bottom plate 803 supports the substrate 2 to move vertically upward. At this time, the fixed plate 807 and the rotating shaft 806 are separated from the fixing hole 804, which is convenient for the operator to take out the substrate 2.

[0054] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
