[0027] like Figure 1-Figure 8 As shown, an embodiment of the utility model is: a material carrying platform 40, mainly composed of a crank rocker safety lock 41, a material placement platform 401, a positioning pin 402, a positioning rib 403, an RFID reader 404, a material arrival detection switch 405, a material presence detection switch 406, a shock-absorbing bracket 407, a storage position electrical interface B408, a mounting surface 409, an auxiliary mounting pin 4010, an unlocking tool guide tube 4014, and an unlocking tool insertion hole 4015.

[0028] Among them, the crank rocker safety lock 41 is composed of a drive motor 4101, a coupling 4102, a mounting frame 4103, a crank output shaft 4104, a rocker 4105, a C-type lock 4106, a limit pin 4107, an unlocking sensor 4108, a locking sensor 4109, a roller 4110, a manual unlocking slot 4111, a hinge point A4112, a hinge point B4113, and a hinge point C4114.

[0029] The position relationship of each component is as follows Figure 1-Figure 6As shown, the material carrying platform 40 is flat in shape, and its upper surface is a material placement platform 401 with a planar structure. The material placement platform 401 is provided with at least two positioning pins 402 for material positioning, which are in the shape of a cone with a small top and a large bottom, and their positions correspond to the bottom positioning grooves of the material A4011; at least three positioning retaining edges 403 are also provided, which have an oblique angle, and the normal direction of the oblique angle points to the center of the material placement platform, surrounding the material located in the middle of the platform; at least two groups of material in-place detection switches 405 are also provided for detecting whether the material is in place, and the principle is to press and trigger, and only when all the material in-place detection switches 405 are triggered at the same time, it means that the material is in place; there is also an RFID reader 404, which is located at the material placement platform 40 1, facing the RFID chip at the bottom of the material A4011, which can identify the identity information of the material; a set of material detection switches 406 are also provided, located in the center of the material placement platform 401, for detecting whether there are materials or other objects on the platform; a set of crank rocker safety locks 41 are also provided, located in the center of the material placement platform, and their function is to lock the material A4011 placed on the material placement platform 401 in a programmable manner to prevent the material from falling and being taken away abnormally by personnel. It has a self-locking function. Once locked, it must be unlocked by program control or opened by special tools in a special way, which ensures the safety of the material and ensures that the material can be taken away in an emergency when the equipment stops abnormally.

[0030] On the side of the material carrying platform 40, there is a flat mounting surface 409 perpendicular to the material placement platform 401, which serves as an interface for connecting the material carrying platform 40 with other devices; a pair of auxiliary mounting pins 4010 are arranged on the mounting surface 409, which are in the shape of a large head and a small rod, with the large head facing outward, and can be inserted into the V-shaped groove structure to position and suspend the entire material carrying platform 40, bringing convenience to assembly; a storage position electrical interface B408 is arranged below the mounting surface 409, and the quick plug structure can realize the rapid plugging of the material carrying platform 40 and the installed device to complete the electrical communication connection. This design allows the material carrying platform 40 to be easily installed on a fixed shelf or a mobile AGV platform.

[0031] In order to achieve shock absorption of the material placement platform 401, a number of shock-absorbing brackets 407 are arranged underneath it, one end of which is connected to the material placement platform 401, and the other end is connected to the frame of the material carrying platform 40. The vibration filtering characteristic of the shock-absorbing brackets 407 can greatly reduce or eliminate the vibration transmitted from the frame of the material carrying platform 40 to the material placement platform 401.

[0032] The main structure of the crank rocker safety lock 41 is located below the material placement platform 401. Along the axis direction of the drive motor 4101, there are the coupling 4102 and the crank output shaft 4104. The crank output shaft 4104 is connected to the output shaft of the drive motor 4101 through the coupling 4102. The drive motor 4101 is installed at one end of the mounting frame 4103, and the crank output shaft 4104 is installed at the other end. The other two sides of the mounting frame 4103, i.e., the two sides of the coupling 4102, are installed with an unlocking sensor 4108 and a locking sensor 4109. , these two sensors can detect the rotation position of the coupling 4102, that is, the rotation position of the crank output shaft 4104; the end face of the crank output shaft 4104 is provided with an eccentric hinge point B4113 and an eccentric limit pin 4107; the rocker 4105 is in the shape of a long strip with holes at both ends, which can be respectively hinged to the hinge point B4113 on the crank output shaft 4104 and the hinge point A4112 on the C-type lock buckle 4106; the C-type lock buckle 4106 is in the shape of the letter C, with a hinge point C4114 at the center, and hinge points A4112 and rollers 4110 at both ends.

[0033] The working principle of the crank rocker safety lock: the output torque of the driving motor 4101 is transmitted to the crank output shaft 4104 through the coupling 4102. The rotation of the crank output shaft 4104 drives the rocker 4105 to move through the eccentric hinge point B4113. The movement of the rocker 4105 drives the C-type lock 4106 to rotate around the hinge point C4114 through the hinge point C4114, thereby changing the position of the roller 4110. When the roller 4110 is in the low position, the material A4011 is in the unlocked state. Figure 3 , Figure 7 As shown; when the roller 4110 is in the high position, the material A4011 is in a locked state, such as Figure 4 , Figure 8 The states of the roller 4110 being in the low position and the high position correspond to the states of the unlocking sensor 4108 and the locking sensor 4109 being triggered, respectively, so it can be determined whether the material A4011 is in the unlocked or locked state at this time.

[0034] like Figure 7As shown, when the roller 4110 is in the low position, the drive motor 4101 rotates counterclockwise, the crank output shaft 4104 also rotates counterclockwise, and the rocker 4105 moves to the right under the pull of the hinge point B4113, driving the C-type lock 4106 to rotate counterclockwise around the hinge point C4114, so that the roller 4110 moves from the low position to the high position. The roller 4110 is in rolling contact with the material A 4011 to avoid dust generated by friction. At this time, the roller 4110 presses the limiting structure of the material A4011 so that the material A4011 cannot move upward. At the same time, the positioning pin 402 and the positioning retaining edge 403 restrict the material A4011 in several other directions. The six degrees of freedom of the material A4011 are all restricted. At this time, the material A4011 is firmly positioned on the material placement platform 401. On the contrary, Figure 8 As shown, in the locked state, the drive motor 4101 rotates clockwise to unlock the material.

[0035] Due to the presence of the limit pin 4107, the movement of the rocker 4105 is limited so that the rotation of the crank output shaft 4104 is also limited within a certain angle range. Figure 8 As shown, when the blocking pin 4107 contacts the rocker 4105, the center line of the hinge point A4112 and the hinge point B4113 is above the rotation center of the crank rocker 4104. At this time, if an upward force is applied to the roller 4110, the rocker 4105 will tend to move to the left, and the crank output shaft 4104 will tend to move counterclockwise, but the limit pin 4107 limits the movement of the crank output shaft 4104, so that it cannot rotate counterclockwise but can only rotate clockwise, and clockwise rotation will cause the roller 4110 to tend to move downward, that is, the roller 4110 exerts a greater pressure on the material A4011. These mechanisms enable the crank rocker safety lock 41 to still have a locking function when the drive motor 4101 is powered off, that is, self-locking ability.

[0036] There is a long and flat groove, namely the manual unlocking groove 4111, in the center of the crank output shaft 4104. A tool such as a flat screwdriver can be inserted into the groove. When emergency unlocking is performed, the tool can be inserted from the unlocking tool insertion hole 4015 through the unlocking tool guide tube 4014 and then inserted into the manual unlocking groove 4111. Applying a clockwise rotation force on the tool can unlock the material A4011.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
