Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical devices for adjusting position and posture, and in particular relates to a device for regulating the body position and posture of larvae. Background Technology

[0002] Automated machinery often offers better operational consistency and higher production efficiency, and is gradually replacing traditional manual operations in many fields. In the large-scale artificial cultivation of Cordyceps sinensis, active and healthy ghost moth larvae are selected as suitable hosts. After artificial anesthesia, they are injected with *Hepialus sinensis* fungus to obtain ghost moth larvae infected with this fungus. After undergoing larval rigor mortis and other cultivation stages, the final result is an insect body structure with a complex Cordyceps sinensis morphology. During the inoculation and infection process, strict control of the temperature, humidity, light, and ventilation of the inoculation environment is necessary to prevent infection by harmful organisms such as mites.

[0003] Currently, the industry uses manual handling to inoculate ghost moth larvae. In this process, after seeing the larvae on the production line, the operator first adjusts them to a "head-forward, tail-back" position; then, using two fingers to pick up the larvae and support them with the palm of their hand, they twist the larvae so that its abdomen faces the operator; finally, using a syringe needle containing bacterial solution, they inject *Heterozoa sinensis* into the larvae's abdomen, specifically the third to fourth segment from the bottom. These actions require a high level of skill from the operator, and the picking, twisting, and supporting movements need to be coordinated skillfully. Prolonged operation often results in significant mental stress and a sense of intense fatigue for the operator. Chinese patent ZL202422190566.7 discloses an automatic material handling robotic arm based on an injection molding machine, using two sets of clamping components and a telescopic cylinder to clamp and flip materials. However, this design is complex, has high operation and maintenance costs, and struggles to achieve continuous rotational flipping of the clamped parts. Therefore, there is an urgent need to design a new mechanical device that can simultaneously flip the insect's abdomen up and down, adjust the inoculation position forward and backward, and automatically press and fix it during the dyeing process. Summary of the Invention

[0004] In view of the defects and deficiencies in the existing technology, this utility model aims to provide a larval body position and posture adjustment device, which can realize the belly flip of the ghost moth larva facing upward, the front and rear position adjustment of the larva, and automatic pressing and fixing.

[0005] The technical solution adopted in this utility model is: a larval body position and posture adjustment device, which consists of a stepper motor, a base plate, gears, a ratchet, a pushing mechanism, a drop groove, a housing, a synchronization mechanism, a flipping roller, a pressing mechanism, and a control system; when the stepper motor rotates in the forward direction, it can drive the gears, ratchet, pushing mechanism, and synchronization mechanism to push to the left and simultaneously rotate to adjust the anesthetized and dormant larvae between the flipping rollers, or when the stepper motor rotates in the reverse direction, it can reset the pushing mechanism to the initial position; the drop groove can collect larvae that fall from either end of the flipping roller; the stepper motor and the housing are mounted on the base plate.

[0006] Furthermore, the gear is mounted on a pushing mechanism, which includes a double-screw screw, a locking nut, a push plate nut, and a T-shaped push plate fixed on the push plate nut.

[0007] Furthermore, the top of the drop trough is provided with flanges around its perimeter, and the bottom center is provided with a drop outlet.

[0008] Furthermore, the clamping mechanism includes a push-pull magnet, a spring, a clamping bracket, a quick-release pin, a universal joint, a clamping claw, an elastic stop pin, a slide groove, and a corner bracket; the push-pull magnet and the clamping bracket are mounted on the housing; a spring is installed between the push-pull magnet and the clamping bracket; the push-pull magnet is connected to the universal joint and the clamping claw via the quick-release pin.

[0009] Furthermore, the clamping claw includes a clamping palm, a covering layer, a clamping arm, and a stop pin hole; the clamping palm is a palm-shaped three-finger claw, with the claw fingers covered by a covering layer.

[0010] Compared with the prior art, the beneficial effects of the larval body position and posture control device of this utility model after adopting the above technical solution are as follows: This device only requires the forward and reverse rotation of a single stepper motor to realize the belly flipping and the forward and backward movement of the larvae of the ghost moth. It has a compact structure and is easy to use and maintain. After the position and posture of the larvae are determined, the larvae can be clamped by pushing and pulling the magnets. It is efficient and has low stress. The clamping and fixing action is achieved by only a pair of flipping rollers and the covering layer of the pressing mechanism. It can be widely used for circumferential and axial positioning and clamping and fixing of larvae and other slender rod-shaped objects. Attached Figure Description

Detailed Implementation

[0012] The following description, in conjunction with the accompanying drawings and specific embodiments provided by the inventor, further illustrates the larval posture control device of this utility model. Any components not described in detail in this invention, or the connections between components, are based on existing technology.

[0013] Figure 1 This is a schematic diagram of the overall assembly structure of a larval body position and posture control device of this utility model, which consists of a stepper motor 1, a base plate 2, a gear 3, a ratchet 4, a pushing mechanism 5, a drop groove 6, a housing 7, a synchronization mechanism 8, a flipping roller 9, a pressing mechanism 10, and a control system 11. When the stepper motor 1 rotates in the forward direction, it can drive the gear 3, ratchet 4, pushing mechanism 5, and synchronization mechanism 8 to push to the left and simultaneously rotate and adjust the anesthetized and dormant larvae between the flipping rollers 9, or reset the pushing mechanism 5 to its initial position when the stepper motor 1 rotates in the reverse direction. The drop groove 6 can collect larvae that fall from either end of the flipping roller 9. The stepper motor 1 and the housing 7 are mounted on the base plate 2. The pressing mechanism 10 can flip the pressing claw 106 to press and fix the larvae.

[0014] Figure 2 This is a schematic diagram of the pushing mechanism of a larval body position and posture control device according to this utility model. The gear 3 is mounted on the pushing mechanism 5. The pushing mechanism 5 includes a double helical screw 51, a locking nut 52, a push plate nut 53, and a T-shaped push plate 54 fixed on the push plate nut 53. The T-shaped push plate 54 can reciprocate linearly within the sliding grooves of the front and rear side plates of the housing 7.

[0015] Figure 3 This is a schematic diagram of the structure of the drop trough of a larval body position and posture control device of the present invention. The top of the drop trough 6 is provided with flanges 61 around its perimeter, and the bottom center is provided with a drop port 62.

[0016] Figure 4 This is a schematic diagram of the clamping mechanism of a larval body position and posture control device according to the present invention. The clamping mechanism 10 includes a push-pull magnet 101, a spring 102, a clamping bracket 103, a quick-release pin 104, a universal joint 105, a clamping claw 106, an elastic stop pin 107, a slide groove 108, and a corner bracket 109. The push-pull magnet 101 and the clamping bracket 103 are mounted on the housing 7. The spring 102 is installed between the push-pull magnet 101 and the clamping bracket 103. The push-pull magnet 101 is connected to the universal joint 105 and the clamping claw 106 through the quick-release pin 104. The elastic stop pin 107 reciprocates within the trajectory line of the slide groove 108 and guides the universal joint 105 to perform a bending movement in the "vertical-horizontal" direction.

[0017] Figure 5 This is a schematic diagram of the structure of the clamping claw of the larval body position and posture control device of the present invention. The clamping claw 106 includes a clamping palm 1061, a covering layer 1062, a clamping arm 1063 and a stop pin hole 1064; the clamping palm 1061 is a palm-shaped three-finger claw, and the covering layer 1062 is attached to the outer sleeve of the claw fingers.

[0018] The process of using the larval body posture control device of this utility model is as follows:

[0019] S1 The bat moth larva falls between the turning rollers 9. The control system 11 automatically controls the stepper motor 1 to rotate forward according to the current state of the larva. The gear 3 drives the ratchet 4 to rotate, pushing the larva from the right end to the left end of the turning roller 9 and continuously turning it over until the larva's belly is facing up and the third to fourth segments from the bottom of the larva's body are located in the middle of the two T-shaped push plates.

[0020] When the S2 control system 11 is powered on, it drives the push-pull magnet 101 to move upward, compresses the spring 102, and the universal joint 105 to move upward. The elastic stop pin 107 slides along the trajectory line in the slide groove 108, and the clamping claw 106 flips downward. The covering layer 1062 contacts and clamps the larva to fix it.

[0021] After the injection process is completed, the control system 11 cuts off the power to the push-pull magnet 101, the spring 102 relaxes, the universal joint 105 retracts, the elastic stop pin 107 resets along the track line of the slide groove 108, and the clamping claw 106 lifts up to release the inoculated bat moth larvae.

[0022] The S4 control system 11 controls the stepper motor 1 to rotate forward. The inoculated larvae are continuously pushed from the right end to the left end of the turning roller 9 and continuously turned and rolled until they fall into the drop trough 6 and fall out from the discharge port 62.

[0023] The S5 control system 11 controls the stepper motor 1 to flip, and the ratchet 4 will isolate the transmission so that the flipping roller 9 does not rotate, but the T-shaped push plate 54 will move from the left end to the right end until it returns to the initial position.

[0024] S6 Repeat steps S1 to S5 to complete the body position adjustment and compression of the next bat moth larva.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of protection of this utility model.
