[0049] like Figure 8As shown, the distribution control component 7 includes a distribution control gear 701, a distribution controller 702 and a distribution claw component 705.

[0050] The stepper motor drives the timing gear set, the pick-up control component and the distribution control component through the driving gear as follows ( Fig.13 As shown) timing operation:

[0051] In the initial state: the picking claw assembly disclosed in the present invention includes a picking claw and a picking connecting rod, the picking claw is hinged to the picking connecting rod, and the picking connecting rod is hinged to the picking claw connecting flange, so that in the process of forward and reverse rotation of the picking controller, the picking connecting rod can rotate with the picking controller to reach the left limit position, the center limit position and the right limit position, and the picking claw is limited in rotation by the claw outlet, so that it moves along the radial direction of the sleeve under the drive of the picking connecting rod, thereby extending out of the sleeve and retracting into the sleeve (when the connecting rod is at the left and right limit positions, the picking claw retracts into the sleeve, and when the connecting rod is at the center limit position, the picking claw extends out of the sleeve). Similarly, the distribution claw can reach the left limit position, the center limit position and the right limit position as the distribution controller rotates; when the timing gear, the picking control gear and the distribution control gear are in the initial position, the picking control gear is in the initial position. The three picking connecting rods in the assembly and the three dispensing connecting rods in the dispensing control assembly are all in the right extreme position. At this time, the picking claws and dispensing claws controlled by each connecting rod are in a retracted state. The device is moved to the optical disc magazine, and the sleeve is passed through the center holes of multiple optical discs in the optical disc magazine; the driving gear 4 is meshed with the first tooth body 501, and the regular tooth area 5021 of the second tooth body and the said picking regular tooth area 6011 will enter a meshing state to drive the picking control assembly 6 to rotate, and the front arc area 5031 of the third tooth body and the said front locking arc area 7011 of the distribution will enter a matching state. The matching state in each timing of the present application refers to the arc area of ​​the driving gear (the second tooth body and the third tooth body of the timing gear) and the locking arc area of ​​the driven gear (the picking gear and the dispensing gear) are in contact, while the regular tooth areas of each other are not meshed, that is, the driven wheel is not driven. At this time, the picking claw assembly 6 and the dispensing claw assembly 7 are both retracted into the sleeve 2. At this time, the sleeve 2 can be inserted into the center hole of the optical disc to facilitate picking up the optical disc. The sleeve can pick up multiple optical discs at a time, twelve in the figure;

[0052] Optical disc picking process: the driving gear 4 drives the first tooth body 501 to rotate, the second tooth body regular tooth area 5021 meshes with the regular picking tooth area 6011 and drives the picking control assembly 6 to rotate, the front arc area 5031 of the third tooth body cooperates with the front locking arc area 7011 of the distribution, and during the rotation of the picking control assembly 6, the picking claw assembly 605 changes from a state of being retracted into the sleeve to a state of being extended out of the sleeve from the clamping claw outlet 201, and the dispensing claw assembly 705 remains in a state of being retracted into the sleeve, and the picking claw assembly extends out of the sleeve to support the optical disc on the sleeve to achieve the picking of the optical disc;

[0053] Specifically, the process is a process for picking up optical discs. In the process, the rotation of the picking controller causes the picking connecting rod to move from the right extreme position to the middle position between the right extreme position and the center extreme position, and the picking claw changes from the state of being retracted into the sleeve to the state of being half extended out of the sleeve. At this time, the optical disc is held by the picking claw, the dispensing connecting rod maintains the right extreme position, and the dispensing claw maintains the state of being retracted into the sleeve.

[0054] The first stage of optical disc distribution process: the driving gear 4 continues to drive the first tooth body 501 to rotate, the second tooth body regular tooth area 5021 meshes with the pickup regular tooth area 6011 to continue to drive the pickup control component to rotate, the third tooth body front regular tooth area 5032 meshes with the distribution front regular tooth area 7012 to drive the distribution control component 7 to rotate, during this process, the pickup claw assembly 605 remains in a state of extending out of the sleeve, the distribution claw assembly 705 changes from a state of being retracted into the sleeve to a state of extending out of the sleeve from the claw outlet, and the distribution claw assembly is inserted between the two optical discs at the bottom;

[0055] Specifically, in the first stage of the optical disc dispensing process, the picking connecting rod moves from the middle position of the center limit to the center limit position, the picking claws are fully extended to hold the optical disc, the dispensing connecting rod moves from the right limit position to the middle position of the right limit and the center limit, the dispensing claws are half extended out of the sleeve, and the bottom layer and the second bottom layer optical discs are separated;

[0056] The second stage of optical disc distribution process: the driving gear 4 continues to drive the first tooth body 501 to rotate, the second tooth body regular tooth area 5021 meshes with the pickup regular tooth area 6011 to continue to drive the pickup control assembly 6 to rotate, and the third tooth body rear arc area 5033 cooperates with the distribution rear locking arc area 7013. During this process, the pickup claw assembly 605 changes from a state of extending out of the sleeve to a state of retracting from the claw outlet into the sleeve, and the distribution claw assembly 705 remains in a state of extending out of the sleeve. At this time, the optical disc at the bottom loses the support of the pickup claw assembly, and the optical disc at the bottom begins to separate from the sleeve;

[0057] Specifically, in the second stage of the optical disc distribution process, the pick-up connecting rod moves from the center limit position to the left limit position, the pick-up claw retracts into the sleeve, the distribution connecting rod maintains the middle position between the right limit and the center limit, the support portion of the distribution claw extends, and the bottom optical disc loses its support. The bottom optical disc should be distributed by its own weight, but the optical discs may be adhered to each other due to water vapor and other reasons, resulting in the undesirable phenomenon that the bottom optical disc cannot fall. Therefore, the third stage of the optical disc distribution process designed by the present invention;

[0058] The third stage of optical disc dispensing process: the driving gear 4 continues to drive the first tooth body 501 to rotate, the arc area 5022 of the second tooth body cooperates with the pickup locking arc area 6012, and the rear regular tooth area 5034 of the third tooth body meshes with the rear regular tooth area 7014 of the dispensing. During this process, the pickup claw assembly 605 remains retracted into the sleeve, and the dispensing claw assembly 705 remains extended out of the sleeve. At this time, the optical disc at the bottom loses the support of the pickup claw assembly, and the dispensing claw assembly drives the optical disc at the bottom to move downward, and the optical disc at the bottom is separated from the sleeve under the push of the dispensing claw assembly.

[0059] Specifically, in the third stage of the optical disc dispensing process, the pick-up connecting rod maintains the left extreme position, the dispensing connecting rod moves to the center extreme position, the pick-up claw maintains the retracted state, the dispensing claw separation part extends, the dispensing claw separation guide surface drives the bottom optical disc to move downward, and the bottom optical disc is peeled off by the dispensing claw, so as to avoid the undesirable phenomenon that the optical discs may be stuck to each other due to water vapor and the like, and then the bottom optical disc cannot be dropped;

[0060] The fourth stage process of optical disc distribution: the driving gear drives the first tooth body to rotate in the opposite direction to the initial state of the first stage process of optical disc distribution. Specifically, the stepping motor rotates in the opposite direction, and the driving gear drives the first tooth body to rotate in the opposite direction, and the third stage process of optical disc distribution, the second stage process of optical disc distribution and the reverse process of the first stage process of optical disc distribution are performed in sequence, so that the optical disc picking and distributing device returns to the state before the first stage of optical disc distribution, that is, after the optical disc picking process: the picking claw assembly extends out of the sleeve to support the optical disc, and the distributing claw assembly retracts until the sleeve is about to be inserted between the two lowest optical discs, and then the first stage process of optical disc distribution, the second stage process of optical disc distribution, the third stage process of optical disc distribution and the fourth stage process of optical disc distribution are continued in sequence to complete the distribution of new optical discs. When all the optical discs in the sleeve are distributed, the optical disc picking and distributing device disclosed in the present invention returns to the initial state to carry out the next optical disc picking and distribution;

[0061] Specifically, the picking connecting rod returns to the middle position between the right limit and the center limit, the dispensing connecting rod returns to the right limit position, the picking claw returns to the half-extended state, and the dispensing claw returns to the retracted state to facilitate the distribution of the next optical disc.

[0062] Furthermore, if Fig.11 As shown, the dispensing claw 703 includes a supporting portion 7031 and a separating portion 7032;

[0063] The front end of the dispensing claw 703 is a supporting portion 7031, and the rear end is a separating portion 7032, and the rear separating portion is hinged to the dispensing connecting rod 704. The front supporting portion is in the shape of a thin sheet, so that it can be inserted into the gap between two adjacent optical discs; the lower side of the rear separating portion is a separating guide surface 7033, which is a wedge-shaped surface, so that when the dispensing claw extends outward, the optical disc to be separated is pushed downward by the separating guide surface, thereby ensuring the successful distribution of the optical disc.

[0064] Furthermore, each of the picking claw assembly 605 and the dispensing claw assembly 705 has multiple groups, and the multiple groups of the picking claw assemblies 605 are evenly distributed along the circumference of the picking controller; the multiple groups of the dispensing claw assemblies 705 are evenly distributed along the circumference of the dispensing controller. In the present embodiment, each of the picking claw assemblies and the dispensing claw assemblies has three, and the angle between two adjacent picking claws or two adjacent dispensing claws is 120°. Multiple groups of picking claw assemblies and dispensing claw assemblies are provided to ensure uniform force on the optical disc, thereby ensuring the reliability of picking up and dispensing the optical disc and protecting the optical disc from damage.

[0065] Furthermore, a disc insertion guide surface 202 is provided at one end of the sleeve 2 away from the base 1. The disc insertion guide surface can facilitate the insertion of the sleeve into the center hole of the disc.

[0066] The existing optical disc picking and dispensing device technology has a large number of transmission parts, and the complex transmission structure will reduce the working efficiency and reliability of the system. The transmission mechanism in the device of the present invention is composed of only a motor, several gears, several groups of connecting rods and claws and other small parts. Since the entry and exit timing of the picking claw and the dispensing claw is different in each stage of picking up and dispensing the optical disc, the second tooth body and the third tooth body on the timing gear, as well as the tooth shapes of the picking control gear and the dispensing control gear corresponding to them are designed into an intermittent gear pattern according to the timing requirements (the intermittent gear is as follows Fig.12 As shown, that is, the driving wheel A and / or the driven wheel B are partially provided with conventional teeth, and partially provided with conventional teeth, so as to achieve the purpose of intermittent driving), wherein the second and third teeth of the timing gear as the driving wheel are provided with conventional tooth areas and arc areas, and the picking control gear and the distribution control gear as the driven wheel are provided with conventional tooth areas and locking arc areas, so that only one driving motor and one timing gear are needed to simultaneously drive the picking control gear and the distribution control gear in certain stages, and only one of the gears is driven and the other gear does not rotate in certain stages; and the spur gear transmission is adopted, which has a simple and compact structure, high transmission efficiency and transmission accuracy, safe and reliable performance, and long service life; in addition, the manufacturing and installation requirements for the gears are relatively low, which is also conducive to the control of material costs and manufacturing costs.

[0067] Meanwhile, most of the prior art do not have the function of preventing the optical disc from sticking, and the few devices with this function require an additional mechanism for peeling the optical disc. The device of the present invention not only has the function of preventing the optical disc from sticking, but also integrates the mechanism for realizing this function with the optical disc separation mechanism, which has a simple structure, high functional integration and reliable performance.

[0068] 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 according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
