Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Example 1: Refer to Figure 1 - Figure 4 A simple bidirectional positioning mechanism includes a tray base plate 001, which is used to place a food tray 005. A base plate 100 is provided on the back of the tray base plate 001 for mounting transmission and clamping components. A miniature electric push rod 101 is provided on one side of the base plate 100 as a power source. A nylon anti-loosening nut 102 and a first locking screw 103 are provided on one side of the miniature electric push rod 101. A push rod adapter 104 is fixedly installed between the nylon anti-loosening nut 102 and the first locking screw 103. The miniature electric push rod 101 pushes the push rod adapter 104 to move back and forth. A slider adapter plate 107 is fixedly installed on one side of the push rod adapter 104 for mounting a slider 114. A Y-axis positioning plate 002 is mated to one side of the slider adapter plate 107 to achieve a clamping effect in the Y-axis direction. The Y-axis positioning plate 002, the push rod adapter 104, and the slider adapter plate 107 are screwed together with slider adapter plate fixing screws 105 to achieve a fixed connection. Countersunk screws 106 are provided around the slider adapter plate 107 to secure it.
[0023] The surface of the substrate 100 is arrayed with copper pillars 108, which are structures that define the rotation range of the disk connecting rod 109.
[0024] A circular connecting rod 109 is provided on the side of the slider adapter plate 107. Second locking screws 110 are provided at both ends of the circular connecting rod 109. A circular disc 113 is rotatably mounted on the other side of the circular connecting rod 109. The circular connecting rod 109 rotates and converges or expands on the surface of the circular disc 113. A circular pressure plate 111 and a circular pressure plate fixing screw 112 are provided in the middle of the disc 113, serving as a limiting structure for the disc 113.
[0025] The slider adapter plate 107 has a slider 114 slidably mounted inside. A guide rail 115 is provided on one side of the slider 114. The slider 114 slides back and forth on the surface of the guide rail 115, thereby driving the Y-axis positioning plate 002 or the X-axis positioning plate 004 to slide back and forth, thus achieving the effect of clamping or gathering. A guide rail fixing screw 116 is provided on the side of the guide rail 115 for fixing the guide rail 115.
[0026] The aforementioned transmission structure is mounted on the back of the substrate 100 in a four-sided array, and the clamping or releasing of the clamping plate is achieved by clockwise convergence or counterclockwise expansion.
[0027] The surfaces of the slider adapter plates 107 on both sides are respectively fixed with Y-axis positioning plate 002 and X-axis positioning plate 004, which serve as positioning and clamping components on both sides. The Y-axis positioning plate 002 and X-axis positioning plate 004 are fixed to the slider adapter plate 107 by slider adapter plate fixing screws 105.
[0028] A simple bidirectional positioning mechanism is provided, in which a tray fixing screw 003 is installed between the tray base plate 001 and the base plate 100 to achieve the connection and fixation between the two. A food tray 005 is provided in the middle part of the tray base plate 001, which is the basis for 3D printing.
[0029] A simple bidirectional positioning mechanism is provided, wherein a bearing 117 is provided in the middle part of the disc 113, and a disc shaft 118 is installed in the middle part of the bearing 117. The bearing 117 and the disc shaft 118 are used to realize the rotation of the disc 113. A retaining spring 119 is provided on one side of the disc shaft 118. The function of the retaining spring 119 is to realize the disc 113 to rebound and reverse when the angle is at its maximum value. A push rod fixing screw 120 is fixedly installed on one side of the miniature electric push rod 101 for fixing the miniature electric push rod 101.
[0030] Working principle:
[0031] Brief action process:
[0032] 1) The food tray 005 is placed on the tray base plate 001 manually or automatically, and then placed inside the two X-axis positioning plates 004 and the two Y-axis positioning plates 002.
[0033] 2) The printer control board controls the movement of the mini electric push rod 101. The push rod of the mini electric push rod 101 drives the push rod adapter 104 and the connected parts to it, which ultimately drives the two X-axis positioning plates 004 and the two Y-axis positioning plates 002 to move inward.
[0034] 3) When the two X-axis positioning plates 004 and the two Y-axis positioning plates 002 finally stop, the distance between them is equal to or slightly less than the outer dimensions of the food tray. Therefore, when they stop, they restrict the position of the food tray 005, thus playing a positioning role.
