In this embodiment, a plurality of universal wheels are installed at the bottom of the box body 1 to facilitate the movement of the box body 1. The oven main body is installed inside the box body 1 for chip mounting and glue filling. The oven main body includes a pressure barrel body 9 and a box door assembly 8 which is openably arranged at the open end of the barrel body 9. The box door assembly 8 is rotatably installed along its own circumference at the moving end of the axial moving module 6, and a rotating driving member 7 for driving the box door assembly 8 to rotate is connected between the box door assembly 8 and the axial moving module 6. The fixed end of the axial moving module 6 is fixedly installed on the radial moving module 5, and the radial moving module 5 is installed on the box body 1 for controlling the axial moving module 6 to make a linear motion.

[0025] Specifically, Figure 3 , Figure 4 and Figure 5 As shown, the radial movement module 5 includes a driving cylinder 151 and a mounting frame 53. The axis of the driving cylinder 151 is arranged along the radial direction of the barrel body 9, and the mounting frame 53 is fixedly installed on the telescopic end of the driving cylinder 151. When the driving cylinder 151 is extended and retracted, the mounting frame 53 is driven to move synchronously along the radial direction of the barrel body 9. In this embodiment, the driving cylinder 151 is fixedly installed on the mounting plate 11 of the box body 1. The driving cylinder 151 has two, which are arranged on the upper and lower sides of the barrel body 9 and are parallel to each other. The mounting frame 53 adopts a frame structure. A slider 531 is fixedly provided on the side of the mounting frame 53 close to the box body 1. A slide rail 52 matching the above-mentioned slider 531 is fixedly provided on the box body 1. The axis of the slide rail 52 is parallel to the axis of the driving cylinder 151. The mounting frame 53 is slidably connected to the slide rail 52 through the slider 531. The axial movement module 6 is installed on the mounting frame 53.

[0026] The axial moving module 6 includes a driving cylinder 61, a moving plate 62 and a mounting plate 63. The axis of the driving cylinder 61 is parallel to the axis of the barrel body 9. One end of the driving cylinder 61 is fixedly connected to the mounting frame 53, and the other end of the driving cylinder 61 is connected to the moving plate 62. The mounting plate 63 is fixedly connected to the moving plate 62. When the driving cylinder 61 is extended or retracted, it can drive the moving plate 62 to move along the axial direction of the barrel body 9.

[0027] The door assembly 8 is rotatably mounted on the mounting plate 63. Specifically, a connecting column 83 extending in the axial direction is fixedly provided at the center of the door assembly 8, and a through hole matching the connecting column 83 is provided on the mounting plate 63. The connecting column 83 is rotatably mounted in the through hole of the mounting plate 63, and a locking bolt 10 is installed at the end of the connecting column 83. The threaded rod of the locking bolt 10 is threadedly fixedly connected to the connecting column 83, and the head of the locking bolt 10 is abutted against the end surface of the mounting plate 63. With this structural design, the locking bolt 10 is locked between the door assembly 8 and the mounting plate 63, which can prevent the door assembly 8 from being separated from the mounting plate 63, and can also ensure that the relative rotation between the door assembly 8 and the mounting plate 63 is normal. The door assembly 8 includes an inner door 81, and the outer edge of the inner door 81 is provided with a plurality of protrusions 811 at intervals along the circumferential direction. In this embodiment, the plurality of protrusions 811 are evenly distributed on the outer edge of the inner door 81. A receiving groove 93 is concavely provided on the inner wall of the open end of the barrel body 9. A plurality of recesses 92 connected to the receiving groove 93 are provided on the end surface of the open end of the barrel body 9. The portion between each two adjacent recesses 92 on the barrel body 9 forms a protrusion 91. The protrusion 811 can enter the receiving groove 93 through the recess 92 and align with the protrusion 91 after the inner door 81 rotates. When the protrusion 811 is aligned with the protrusion 91, the inner door 81 cannot move to the outside of the barrel body 9 in the axial direction, that is, the door assembly 8 is prevented from opening by mistake. In order to improve the sealing performance between the inner door 81 and the barrel body 9, a sealing ring 8111 for sealing is provided between the inner door 81 and the barrel body 9 in this embodiment.

[0028] Meanwhile, the door assembly 8 in this embodiment further includes an outer door 82, which is fixedly mounted on the outer side of the inner door 81 and spaced apart from the inner door 81, and the spacing between the inner door 81 and the outer door 82 is greater than the thickness of the second protrusion 91. When the first protrusion 811 of the inner door 81 enters the receiving groove 93, the outer door 82 is located on the outer side of the receiving groove 93.

[0029] In this embodiment, the rotary drive member 7 is a cylinder, one end of which is hingedly mounted on the moving plate 62 or the mounting plate 63 of the axial moving module 6, and the other end of which is hingedly mounted on the outer door 82. The hinged structure is the structure in the prior art. When the cylinder is extended or retracted, it can drive the door assembly 8 to rotate relative to the mounting plate 63.

[0030] A feeding module 3 for feeding is provided on one side of the box body 1 near the box door, and a feeding manipulator 4 for automatically grabbing the material on the feeding module 3 and placing it inside the pressure barrel body 9, and a filtering module 2 for filtering is also provided on the upper part of the box body 1. During operation, the feeding module 3 is responsible for transporting the material to be baked. After the box door assembly 8 of the oven body is opened, the feeding manipulator 4 grabs the material on the feeding module 3 and places it inside the pressure barrel body 9, and then the box door assembly 8 is closed, and the baking operation can be performed. In this embodiment, the specific structure and working principle of the filtering module 2, the feeding module 3 and the feeding manipulator 4 all adopt the structure of the existing technology, and will not be repeated here.

[0031] During the automatic door closing operation, the driving cylinder 1 51 is started, and the driving mounting frame 53 is driven to move radially along the barrel body 9, thereby driving the axial moving module 6 and the box door assembly 8 installed on the axial moving module 6 to move synchronously until the box door assembly 8 is aligned with the opening end of the barrel body 9; then the driving cylinder 1 51 is stopped, the driving cylinder 2 61 is started, and the driving moving plate 62 is driven to move along the axial direction of the barrel body 9 toward the barrel body 9, thereby driving the mounting plate 63 and the box door assembly 8 rotatably mounted on the outer side of the mounting plate 63 to move synchronously until the protrusion 1 811 of the inner box door 81 enters the receiving groove 93 through the recessed portion 92 of the barrel body 9, then the driving cylinder 2 61 is stopped, and the rotating driving member 7 is started, driving the box door assembly 8 to rotate with its own central axis as the rotation center until the protrusion 1 811 is aligned with the protrusion 2 91; at this time, the automatic door closing operation is completed. During the automatic door opening operation, the above operation steps can be reversed.

[0032] The utility model discloses a positive and negative pressure oven with fully automatic door opening, which realizes fully automatic door opening and closing operations through ingenious structural design, can effectively reduce the contact between operators and materials, prevent materials from being contaminated, and improve the degree of automation of the equipment; and after the box door assembly 8 is opened, it moves horizontally to one side of the barrel body 9, fully presenting the open end of the barrel body 9, which is more convenient for automatic loading and unloading; effectively ensures work efficiency and improves operational safety.
