Specific embodiments

[0033] In order to facilitate the understanding of the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below in conjunction with specific embodiments.

[0034] As Figure 1 shown, a three-axis loading machine includes: a base 1, a stock table 2, a feeding assembly 3 and a picking and placing assembly 4; the base 1 is provided with mounting holes for installing the stock table 2, the feeding assembly 3 and the picking and placing assembly 4, and also provided with a groove for installing the stock table 2 and the feeding assembly 3.

[0035] As Figure 2 shown, the stock table 2 includes a support column 21 and a platform 22. The support column 21 is two rectangular prisms, and mounting holes are provided on both the upper and lower surfaces of the rectangular prisms. The platform 22 is a square thick plate, and a countersunk through hole is provided on the side away from the support column 21.

[0036] As Figure 3 shown, the feeding assembly 3 includes a vibrating bowl 31 and a pushing device 32. The vibrating bowl 31 and the pushing device 32 are both detachably fixed on the base 1. An inclined downward material transporting track 311 is provided at the outlet end of the vibrating bowl 31, and the other end of the material transporting track 311 away from the vibrating bowl 31 abuts against the pushing device 32.

[0037] Specifically, the material pushing device 32 includes a linear guide rail 321, a material receiving block 322, a guide rail base 326, a mounting block 323, a driving element 324, and a buffer 325. The guide rail base 326 is press-fitted into the corresponding groove on the base 1 and is detachably fixed on the surface of the base 1. The linear guide rail 321 is detachably fixed on the other surface of the guide rail base 326 away from the base 1. The material receiving block 322 is provided with a countersunk through hole, and a screw penetrates through the countersunk through hole to fix the material receiving block 322 on the surface of the slider of the linear guide rail 321 away from the guide rail. The surface of the material receiving block 322 away from the linear guide rail 321 is also provided with a groove for receiving the annular injection molded part conveyed from the material conveying track 311 of the vibrating disk 31.

[0038] As Figure 6 shown, it should be noted that the shape of the groove matches that of the annular injection molded part, the groove depth is less than the height of the annular injection molded part, and the groove is chamfered at the entrance of the annular injection molded part to facilitate the entry of the annular injection molded part from the material conveying track 311 into the groove.

[0039] Specifically, the number of mounting blocks 323 is two. One is fixed on the end surface of the guide rail base 326 perpendicular to the movement direction of the slider by threaded connection, and the other is fixed on the other end surface of the guide rail base 326 perpendicular to the movement direction of the slider by threaded connection. The driving element 324 and the buffer 325 are fixed on the end surface of the mounting block 323 perpendicular to the movement of the linear guide rail 321. One end of the driving element 324 is fixed on the end surface of the material receiving block 322 perpendicular to the movement direction of the linear guide rail 321.

[0040] It should be noted that the driving element 324 adopts a single-rod double-acting cylinder, and the buffer 325 adopts an oil buffer and the number is two, which is used for buffering when the material receiving block 322 on the linear guide rail 321 makes a reciprocating linear motion along the guide rail.

[0041] As Figure 4 shown, the picking and placing component 4 includes a three-axis linear module 41 and a clamping device 42; the three-axis linear module 41 is assembled on the base 1 and is controlled by an external PLC, and the clamping device 42 is assembled on the three-axis linear module 41.

[0042] Specifically, an angle plate is fixed on the material conveying track 311. The short side of the angle plate covers the upper surface of the material conveying track 311 of the vibrating disk 31 and the width of the short side is less than the width of the track. The long side of the angle plate is provided with a slot hole and is fixed on the side surface of the material conveying track 311 of the vibrating disk 31.

[0043] Specifically, the three-axis linear module 41 includes an X-axis linear module 411, a Y-axis linear module 412, and a Z-axis linear module 413.

[0044] As shown Figure 5 in FIG. 42, the clamping device 42 includes pneumatic fingers 421 and finger attachments 422. The number of finger attachments 422 is two, which are symmetrically fixed on the fingers of the pneumatic fingers 421. A groove matching the outer shape of the ring-shaped injection molded part is provided at one end of the finger attachment 422 away from the pneumatic fingers 421.

[0045] It should be noted that the X-axis linear module 411, the Y-axis linear module 412, and the Z-axis linear module 413 are prior arts, and the pneumatic fingers 421 of the clamping device 42 are prior arts. They are controlled by an external PLC, which are all conventional means and belong to the common general knowledge in the field. The present utility model only uses them without improving them. Moreover, the present utility model mainly aims to protect mechanical devices, so the control method and circuit connection will not be explained in detail in the present utility model.

[0046] The implementation principle of the present utility model is as follows:

[0047] The ring-shaped injection molded part is sequentially conveyed from the feeding track 311 of the vibrating bowl 31 to the groove of the receiving block 322 of the pushing device 32. The cylinder piston rod extends, and the receiving block 322 and the slider fixed on the linear guide 321 are pushed out together along the track direction. When reaching the end of the stroke, it stops after being buffered and decelerated by the oil buffer. The PLC controls the three-axis linear module 41 to drive the clamping device 42 to move to the ring-shaped injection molded part of the receiving block 322. The pneumatic fingers 421 contract towards the center, and the finger attachments 422 clamp the part of the ring-shaped injection molded part that protrudes above the groove of the receiving block 322 as the fingers contract, taking out the ring-shaped injection molded part from the groove. The cylinder piston rod contracts, and the receiving block 322 and the slider return to the initial position along the track direction, and at the same time, they stop after being buffered and decelerated by the oil buffer, enabling the next ring-shaped injection molded part to enter the groove of the receiving block 322. The receiving block 322 is pushed out again, and at the same time, the PLC continues to control the three-axis linear module 41 to move above the storage table 2 and put down the ring-shaped injection molded part, allowing the storage column 221 to penetrate the ring-shaped injection molded part and waiting for the subsequent interlocking machine to take it away at one time. Then the PLC controls the three-axis linear module 41 to continue to clamp the ring-shaped injection molded part from the receiving block 322. This process is repeated, eliminating the manual feeding process, thus solving the problems of low efficiency, high error rate, and high cost of manual feeding.

[0048] In a possible implementation manner, the mounting block 323 is a thick angle plate. A chamfer for guiding the linear movement of the slider is provided on one side of the thick angle plate close to the feeding track 311. A groove for supporting the feeding track 311 is also provided on the plate surface of the thick angle plate parallel to the movement direction of the linear guide 321. The mounting holes provided on the mounting surface of the thick angle plate are slot holes for adjusting the gap between the slider and the plate surface parallel to the movement direction of the linear guide 321.

[0049] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and without departing from the spirit and scope of the present utility model, there will be various changes and improvements to the present utility model, and these changes and improvements all fall within the scope claimed by the present utility model. The scope claimed by the present utility model is defined by the appended claims and their equivalents.
