To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, but not all embodiments.

[0034] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figure 1 As shown, the multi-station direct conveyor in this embodiment is mainly composed of a storage section 1, a pick-and-place section 2, a sheet handling section 3, and a machine body section 4. The machine body section 4 is used to carry and accommodate the above three sections. The storage section 1 adopts a three-station structure to store and accommodate workpieces 1000. The workpiece 1000 is a round steel sheet structure for motor lamination processing. The pick-and-place section 2 adopts a conventional linear module 21 combined with an adsorption module 22. The linear module 21 can be a lead screw transmission module to drive the adsorption module 22 to make horizontal and vertical linear movements. The adsorption module 22 adsorbs the workpiece 1000 and drives it to move. For example, the workpiece 1000 in the storage section 1 is adsorbed to the sheet handling section 3, and then the workpiece 1000 in the sheet handling section 3 is adsorbed to the processing and stamping equipment 5 at the rear. Here, the sheet handling section 3 not only serves to temporarily store the workpiece 1000, but also to locate its center position.

[0037] like Figures 2-4 As shown, specifically, the storage unit 1 consists of a drive module 11, a connector 12, and three storage modules 13. The drive module 11 drives the connector 12 to rotate, and the three storage modules 13 are arranged in a circular array on the connector 12 to store workpieces 1000.

[0038] The drive module 11 consists of a mounting bracket 111 and a drive motor 112. The drive motor 112 is mounted on the mounting bracket 111. The output end of the drive motor 112 is connected to the connecting body 12 through a coupling. The connecting body 12 can be a disc-shaped structure, that is, the connecting body 12 is a turntable.

[0039] The storage module 13 consists of a support body 131, three positioning rod groups, a rotating disk 132, and a fixed disk 133. The support body 131 adopts an equilateral triangle structure. The three positioning rod groups are arranged in a circular array on the support body 131. Here, the positioning rod group consists of a rod part 134, a slide block 135, and a slide rail 136. The rod part 134 is vertically arranged on the slide block 135. The slide block 135 is arranged on the slide rail 136 and moves along the slide rail 136. The line from the center of the support body 131 to the three vertices is set as the reference line. Then, the three slide rails 136 correspond to and coincide with which reference line respectively.

[0040] Furthermore, the rotating disk 132 is also provided with three arc-shaped guide holes 1321 arranged in a circular array. A single rod part 134 passes through a single guide hole 1321, and the rotating disk 132 is thus fitted onto the rod part 134. When the rotating disk 132 rotates, it can drive the positioning rod assembly to move along the guide hole 1321.

[0041] The fixed disc 133 is also sleeved on the rod part 134 and located above the rotating disc 132. The fixed disc 133 is connected to the support body 131. The fixed disc 133 is provided with three linear limiting holes 1331. A single positioning rod group passes through a single limiting hole 1331 and can move along the limiting hole 1331. Here, the position of the slide rail 136 corresponds to that of the limiting hole 1331, that is, the projections of the two on the support body 131 coincide.

[0042] Meanwhile, an auxiliary rod 1322 protrudes from the rotating disk 132, and an arc-shaped auxiliary hole 1332 is provided on the fixed disk 133. The auxiliary rod 1322 passes through the auxiliary hole 1332. When the rotating disk 132 rotates, the auxiliary rod 1322 can move along the auxiliary hole 1332. When the rotating disk 132 rotates, the auxiliary rod 1322 and the auxiliary hole 1332 cooperate to achieve guidance.

[0043] Therefore, by rotating the rotating disk 132, the positioning rod assembly can move linearly back and forth between a corner position of the support body 131 and the center position of the support body 131, thereby ensuring that the three rod parts 134 are all in contact with the round edge position of the workpiece 1000, and stably positioning and storing the material.

[0044] like Figures 5-6 As shown, the processing unit 3 includes a housing 31 and an adjustment assembly disposed on the housing 31. The adjustment assembly includes an adjustment motor 32, a linkage bevel gear 33, and four lead screw positioning modules. The housing 31 adopts a square box structure, and the four lead screw positioning modules are positioned corresponding to the two diagonals of the square. The adjustment motor 32 is connected to the linkage bevel gear 33. The lead screw positioning modules are arranged in a circular array on the housing and are all engaged with the linkage bevel gear 33. The lead screw positioning modules move with the linkage bevel gear 33 and drive the workpiece 1000 on the housing 31 to move.

[0045] The lead screw positioning module includes a second bevel tooth 34, a lead screw 35, a nut seat 36, and a positioning block 37. The second bevel tooth 34 is located at one end of the lead screw 35 and meshes with the linkage bevel tooth body 33. The nut seat 36 is located on the lead screw 35, and the positioning block 37 is located on the nut seat 36.

[0046] Four positioning holes 311 are provided on the upper end face of the housing 31. The positioning holes 311 correspond to the positions of the lead screw positioning module. Thus, the intersection of the positioning holes 311 corresponds to the center position of the workpiece 1000 in the fixed position. The positioning block 37 passes through the positioning hole 311 and protrudes to the top of the housing 31. A single positioning block 37 can move along a single positioning hole 311.

[0047] Therefore, by adjusting the motor 32, the four positioning blocks 37 are moved simultaneously towards the center position, and then the center position of the internal workpiece 1000 is adjusted from four directions to complete the positioning.

[0048] Meanwhile, below the lead screw positioning module, specifically below the housing 31, a manual adjustment module and a base 30 are provided. The base 30 is connected to the body 4 to support the manual adjustment module. The manual adjustment module includes a transmission rod 38, a handle 39, and a female seat. The handle 39 drives the transmission rod 38 to rotate. The female seat is located on the transmission rod 38 and connected to the lower end face of the housing 31. The transmission rod 38 and the female seat have a conventional lead screw and nut structure. By rotating the handle 39, the entire lead screw positioning module can be moved, thereby adjusting its position. Of course, a linear slide rail structure can also be provided between the housing 31 and the base 30 to ensure the straightness and smoothness of the translation.

[0049] like Figure 7 As shown, the structure in which the output end of the drive motor 112 is linked to the coupling can be replaced by the drive motor 112 directly driving the turntable bearing to rotate the disc-shaped coupling.

[0050] like Figure 8 As shown, when this utility model is in use, the pick-and-place unit 2 works to pick up the workpiece 1000 on the storage unit 1 and put it into the sheet handling unit 3. After the sheet handling unit 3 finishes working, the pick-and-place unit 2 picks up the workpiece 1000 on the sheet handling unit 3 and puts it into the stamping equipment 5 to complete one conveying.

[0051] It should be noted that each of the four bottom corners of the machine body 4 is equipped with an electric lifting support 2000 structure. If a screw lifting mechanism is used, the lifting function of the whole machine can be realized.

[0052] This utility model describes preferred embodiments, including the best mode known to the inventors for carrying out the utility model. Of course, variations of these preferred embodiments will be readily apparent to those skilled in the art. The inventors intend that those skilled in the art may use these variations as appropriate, and the inventors indicate that the utility model can be implemented in other ways than those specifically described herein. Therefore, this utility model includes all improvements encompassed by the spirit and scope of the utility model as defined by the claims. Moreover, unless otherwise stated or there is a clear contradiction in the content, this utility model includes any of the foregoing elements and all possible variations thereof.
