[0026] In order to describe the present invention in detail, a loading and unloading turning mechanism and loading and unloading equipment of the present invention are specifically described below:

[0027] Please combine Figure 1 、 Figure 2 and Figure 3As shown, the utility model provides a loading and unloading flipping mechanism, including a lifting module 1 and an extraction module 3, the lifting module 1 includes a mounting seat 103 and a slider 102 movably arranged on the mounting seat 103, the slider 102 has an extended position and a ready position, the slider 102 reciprocates between the extended position and the ready position on the mounting seat 103, and the fixture pick-up position is located on the extension line of the line connecting the extended position and the ready position; the extraction module 3 is rotatably arranged on the slider 102, the extraction module 3 has a first rotation position and a second rotation position, and the extraction module 3 reciprocates between the first rotation position and the second rotation position around the rotation axis of the extraction module 3 The extraction module 3 includes a first pick-and-place component and a second pick-and-place component for picking up and placing the fixtures respectively; when the extraction module 3 is in the first rotation position and the slider 102 of the lifting module 1 is in the extended position, the first pick-and-place component is located at the fixture pick-and-place position to extract the processed fixture on the placement table; when the extraction module 3 is in the second rotation position and the slider 102 of the lifting module 1 is in the extended position, the second pick-and-place component is located at the fixture pick-and-place position to place the fixture to be processed on the placement table; when the slider 102 of the lifting module 1 is in the ready position, the processed fixture on the first pick-and-place component is transferred, and the fixture to be processed is placed on the second pick-and-place component. By setting up a lifting module 1, the extraction module 3 can be driven to reciprocate along the extension direction of the line connecting the extended position and the preparation position. When the slider 102 is in the preparation position, the processed jig on the extraction module 3 can be transferred and the jig to be processed can be placed. The extraction module 3 can reciprocate between the first rotation position and the second rotation position around the rotation axis of the extraction module 3. When the slider 102 is in the extended position, the first pick-up and placement component can extract the processed jig from the placement table, or the second pick-up and placement component can place the jig to be processed on the placement table. In this way, the loading and unloading work can be achieved simultaneously only through the loading and unloading flipping mechanism, and the loading and unloading equipment can be integrated into one, reducing the production and manufacturing costs of the loading and unloading equipment. When the slider 102 is in the preparation position, the work of removing the processed jig and placing the jig to be processed can be carried out, thereby improving the efficiency of jig loading and unloading and having better economic benefits. The jig to be processed on the second pick-up and placement component and the processed jig in the first pick-up and placement interval can be moved and placed manually or by a robot.

[0028] In this embodiment, the jig is a notebook shell 202, which needs to be punched before assembly. It should be noted that the unprocessed jig mentioned in this application is the notebook shell 202 that has not been punched, and the processed jig is the notebook shell 202 that has been punched.

[0029] The mounting base 103 of the lifting module 1 is provided with a limiting protrusion extending in a first direction. The slider 102 has a limiting recess extending in the first direction corresponding to the limiting protrusion. The limiting protrusion is at least partially accommodated in the limiting recess. The first direction is the direction of the line connecting the extended position and the standby position. The provision of the limiting protrusion and limiting recess limits the movement direction of the slider 102, resulting in a good limiting effect, a simple structure, and easy production and assembly.

[0030] In this embodiment, the lifting module 1 includes a second power member 101, a screw and a ball nut seat, and a slider 102 connected to the ball nut seat. The second power member 101 is connected to the screw and drives the screw to rotate around the screw's axis. When the screw rotates in the forward or reverse direction, it can drive the ball nut seat to move in the forward or reverse direction along the first direction, thereby achieving reciprocating motion of the slider 102 between the extended position and the ready position. In conjunction with the limiting protrusion and the limiting recess, the movement direction of the slider 102 can be limited. At the same time, the screw and ball nut seat are used to control the movement position of the slider 102, converting the rotary motion of the screw into linear motion. The lifting module has the characteristics of low friction coefficient, high transmission efficiency, low required transmission torque, high sensitivity, smooth transmission, high tracking accuracy and high positioning accuracy. In this way, when the first pick-and-place assembly and the second pick-and-place assembly pick and place the fixture on the placement table, the situation of squeezing the fixture due to low displacement accuracy is avoided, thereby improving the overall stability of the loading and unloading flipping mechanism during operation. The second power component 101 may be a servo motor, and the type of the second power component 101 may be adjusted according to actual needs.

[0031] Among them, the first pick-and-place assembly and the second pick-and-place assembly both include a base plate 302 and a pick-and-place member 301 arranged on the base plate 302. The pick-and-place member 301 is arranged on the side of the base plate 302 away from the slider 102, and the other side of the base plate 302 is rotatably connected to the slider 102. The extension surfaces of the two base plates 302 intersect at ninety degrees, and the rotation angle of the extraction module 3 between the first rotation position and the second rotation position around the rotation axis of the extraction module 3 is ninety degrees. The extension surfaces of the two base plates 302 are set to ninety degrees, and the rotation angle between the first rotation position and the second rotation position is matched. When the extraction module 3 is in the first rotation position and the slider 102 is in the preparation position, the fixture pick-and-place position is located on the moving track of the first pick-and-place assembly. At this time, it is convenient to place the jig to be processed on the second pick-and-place assembly, so that when the extraction module 3 rotates around the rotation axis of the extraction module 3 to the second rotation position, the fixture pick-and-place position is on the moving track of the second pick-and-place assembly. The above structure is simple and regular, and easy to operate.

[0032] Specifically, the pick-and-place component 301 is a suction cup. In this embodiment, four suction cups are provided on each base plate 302, and the connection line of the four suction cups is a square, which can better suck the jig firmly and prevent the jig from falling during movement. Each suction cup is connected to a vacuum generator. When the jig needs to be sucked, the vacuum generator sucks away the air in the suction cup, and the atmospheric pressure will press the jig and the suction cup tightly together, so that the suction cup can achieve the function of sucking the jig. When the suction cup needs to put down the jig, the vacuum generator introduces air into the suction cup to make the atmospheric pressure inside and outside the suction cup the same, so that the jig falls off the suction cup. Using a suction cup to suck the jig can avoid damaging the jig when taking and placing the jig, and reduce the collision rate of the jig during the production process. In some embodiments, the pick-and-place component 301 can be a clamp, which cooperates with the clamp to grab the jig. The type of the pick-and-place component 301 can be adjusted according to actual needs.

[0033] Specifically, the first pick-and-place assembly and the second pick-and-place assembly further include sensors disposed on the base plate 302. In this embodiment, the sensors are distance sensors. The sensors disposed on the base plate 302 can monitor in real time whether a fixture has been removed or placed when the first or second pick-and-place assembly is picking up or placing the fixture. During operation, they can also detect whether the loading and unloading flipping mechanism is operating in the correct mode, thereby improving its operational stability.

[0034] Specifically, the base plate 302 is provided with a weight-reducing structure, which is a weight-reducing hole 303. Multiple weight-reducing holes 303 are provided on the base plate 302. By providing the weight-reducing holes 303 on the base plate 302, the base plate 302 can be made lightweight, reducing the gravity acting on the lifting module 1 and facilitating the rotation of the extraction module 3. In some embodiments, the weight-reducing structure is a weight-reducing slot. The type of weight-reducing structure can be adjusted based on actual needs.

[0035] like Figure 1 、 Figure 2 and Figure 4As shown, the loading and unloading flipping mechanism also includes a rotating module 2, and the extraction module 3 is connected to the slider 102 through the rotating module 2. The rotating module 2 includes a first power member 201, an annular transmission belt 204, a first rotating wheel 203 and a second rotating wheel 205. The first power member 201 is arranged on the slider 102, and the first rotating wheel 203 is connected to the first power member 201. The first power member 201 is used to drive the first rotating wheel 203 to rotate. The first rotating wheel 203 and the second rotating wheel 205 are both arranged on the inner side of the annular transmission belt 204 and the annular transmission belt 204 is tensioned. When the first rotating wheel 203 rotates, the first rotating wheel 203 and the annular transmission belt 204 drive the second rotating wheel 205 to move and rotate. The second rotating wheel 205 is connected to the extraction module 3 and drives the extraction module 3 to rotate between the first rotation position and the second rotation position. By providing the first rotating wheel 203, the second rotating wheel 205, and the endless transmission belt 204, the first power member 201 can be positioned on the slider 102 near an extension of the slider 102's movement trajectory. This facilitates the rational arrangement of the spatial structure between the rotating module 2 and the lifting module, facilitates wiring, and achieves a neat and aesthetically pleasing appearance. The extraction module 3 can be directly connected to a rotating motor, which drives the extraction module 3 to rotate. The manner in which the extraction module 3 is rotatably positioned on the lifting module 1 can be adjusted based on actual needs. In this embodiment, the first power member 201 is a servo motor. The type of the first power member 201 can be adjusted based on actual usage requirements. In this embodiment, the rotating module 2 also includes a housing 202, which is used to accommodate the endless transmission belt 204, the first rotating wheel 203, and the second rotating wheel 205, preventing the external environment from affecting the transmission of the first rotating wheel 203, the second rotating wheel 205, and the endless transmission belt 204, thereby protecting the first rotating wheel 203, the second rotating wheel 205, and the endless transmission belt 204.

[0036] In this embodiment, the second rotating wheel 205 is connected to the rotating shaft. The second rotating wheel 205 drives the rotating shaft to rotate around its axial direction. The two bottom plates 302 are respectively connected to the rotating shaft through connecting rods 304.

[0037] Specifically, the first rotating wheel 203 and the second rotating wheel 205 are both gears, and the annular transmission belt 204 is a toothed belt, the teeth of the toothed belt meshing with the teeth of the gears. The gears and the toothed bar cooperate to increase the positioning accuracy of the gears during rotation, thereby improving the accuracy and stability of the loading and unloading flipping mechanism. In this embodiment, the radius of the first rotating wheel 203 is smaller than the radius of the second rotating wheel 205. By adjusting the radius of the first rotating wheel 203 and the second rotating wheel 205, the rotation speed and torque of the extraction module 3 can be adjusted. The radius of the second rotating wheel 205 is larger than the radius of the first rotating wheel 203, and the torque of the second rotating wheel 205 is greater than that of the first rotating wheel 203. The rotation speed of the second rotating wheel 205 is slower than that of the first rotating wheel 203. Increasing the torque of the second rotating wheel 205 facilitates the extraction module 3 in removing and placing the fixture, preventing the extraction module 3 from damaging the first power member 201 when removing and placing the fixture.

[0038] The present invention further provides a loading and unloading device, comprising a gantry and at least two loading and unloading flipping mechanisms as described above. The loading and unloading flipping mechanisms are sequentially arranged on the gantry along the extension direction of the gantry, and the loading and unloading flipping mechanisms are connected to the gantry via mounting bases 103 for the loading and unloading flipping mechanisms. By providing at least two loading and unloading flipping mechanisms on the gantry, loading and unloading efficiency can be improved while reducing the cost of installing support components.

[0039] In summary, by setting up the lifting module 1, the extraction module 3 can be driven to reciprocate along the extension direction of the line connecting the extended position and the preparation position. When the slider 102 is in the preparation position, the processed jig on the extraction module 3 can be transferred and the jig to be processed can be placed. The extraction module 3 can reciprocate between the first rotation position and the second rotation position around the rotation axis of the extraction module 3. When the slider 102 is in the extended position, the first pick-up and placement component can extract the processed jig on the placement table, or the second pick-up and placement component can place the jig to be processed on the placement table. In this way, the loading and unloading work can be achieved simultaneously only through the loading and unloading flipping mechanism, and the loading and unloading equipment are integrated into one, reducing the production and manufacturing costs of the loading and unloading equipment. When the slider 102 is in the preparation position, the work of removing the processed jig and placing the jig to be processed can be carried out, thereby improving the efficiency of jig loading and unloading, and having better economic benefits.
