Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example

[0043] See attached Figure 2 , 3 As shown, a clip-type feeding device includes a base plate 1, a contoured clip 2 in which products 8 can be stacked, a clip positioning mechanism 3 in which the contoured clip 2 can be placed and fixed, a blowing device 4 that can blow air into the contoured clip 2, a blocking mechanism 5 that can block the product 1 from rising, a material box moving mechanism 6, and a control module that controls the above-mentioned mechanisms.

[0044] See attached Figure 6 , 7As shown in FIGS. 8 and 9, the profiling clip 2 is provided with a profiling cavity 21 with an upper end opening along its length direction, and a profiling slide block 22 is slidably penetrated in the profiling cavity 21. Specifically, in order to facilitate the processing and installation of the profiling clip 2, in this embodiment, the profiling clip 2 is a split structure, that is, the profiling clip 2 includes a clip middle plate 23 and clip side plates 24 fixedly connected to the clip middle plate 23 by bolts on both sides, and profiling grooves 241 are provided on the two clip side plates 24. The two clip side plates 24 are respectively enclosed with the clip middle plate 23 to form two profiling cavities 21 matching the shape of the product 1, and the product 1 can be stacked and slid in the profiling cavity 21.

[0045] Furthermore, the middle plate 23 of the magazine is a bending structure similar to a “Z” shape, and the two side plates 24 of the magazine are respectively surrounded by the end surfaces of the middle plate 23 of the magazine opposite thereto to form a contoured cavity 21 .

[0046] In order to prevent the profiling slide block 22 from sliding out of the profiling cavity 21 from the lower end of the profiling cavity 21, a limiting rod 25 is fixedly penetrated at the lower part of the two magazine side plates 24 and the magazine middle plate 23, and the profiling slide block 22 is arranged in the profiling cavity 21 above the limiting rod 25.

[0047] In order to make the profiling slide block 22 slide smoothly in the profiling cavity 21, a ball screw 26 is fixedly provided in the profiling slide block 22. The steel column of the ball screw 26 abuts against the magazine middle plate 23 and the magazine side plate 24, and the profiling slide block 22 can slide down due to gravity.

[0048] In order to inflate the contour cavity 21, ventilation holes 27 are respectively provided at the lower parts of the clip middle plate 23 and the clip side plate 24, and the ventilation holes 27 are respectively connected to the corresponding contour cavity 21, and the blowing port of the blowing device 4 is connected to the ventilation holes 27. The blowing device 4 is used to blow air into the contour cavity 21 to drive the contour slider 22 to rise, and the blowing device 4 can be selected from existing equipment, such as an air pump, an air tank, etc.

[0049] Furthermore, in order to facilitate taking and placing the contoured magazine 2, a handle 28 is fixedly connected to the upper part of the contoured magazine 2 by bolts.

[0050] See also Figure 5As shown, the clip positioning mechanism 3 includes a clip positioning plate fixedly connected to the base plate 1 and provided with a clip positioning cavity 31, and a clip fixing cylinder 32 arranged on the clip positioning plate and used to fix the profiling clip 2 in the clip positioning cavity 31. Specifically, the clip positioning plate includes a positioning vertical plate 33 and two positioning side plates 34 which are respectively vertically fixedly connected to the base plate 1 by bolts and enclose the clip positioning cavity 31, and a fixing plate 35 is fixedly connected to the lower end of the two positioning side plates 34 opposite to the positioning vertical plate 33 by bolts, and the clip fixing cylinder 32 is fixedly connected to the fixing plate 35 by bolts, and the guide rod of the clip fixing cylinder 32 can be slidably penetrated in the clip positioning cavity 31. The shape and structure of the clip positioning cavity 31 match the profiling clip 2, so as to facilitate the profiling clip 2 to be placed in the clip positioning cavity 31. When the guide rod of the clip fixing cylinder 32 is extended, it can press against the profiling clip 2, thereby fixing the profiling clip 2.

[0051] In addition, after the contoured clip 2 is placed in the clip positioning cavity 31, the contoured clip 2 is preliminarily positioned and fixed. In the present embodiment, obliquely arranged slots 341 are respectively provided on the upper end surfaces of the two positioning side plates 34 and the positioning vertical plate 33, and the positioning rod 36 is detachably mounted in the slot 341. The contoured clip 2 is arranged in the clip positioning cavity 31 on the inner side of the positioning rod 36.

[0052] See also Figure 4 As shown, in order to improve the overall feeding efficiency of the utility model, two groups of magazine positioning mechanisms 3 are provided on the bottom plate 2, and two groups of contoured magazines 2, blowing devices 4, and blocking mechanisms 5 are also provided correspondingly.

[0053] The blocking mechanism 5 includes three mounting plates 51, namely, left, middle and right, which are horizontally fixedly connected to the upper end surfaces of the two sets of positioning side plates 34 by bolts, blocking cylinders 52 which are fixedly installed on the three mounting plates 51 by bolts in pairs, and blocking blocks 53 which are fixedly connected to the guide rods of the blocking cylinders 52 by bolts. When the guide rods of the blocking cylinders 52 are extended, the blocking blocks 53 move to the top of the corresponding products 1, thereby preventing the products 1 from being separated from the contoured cavity 21.

[0054] Furthermore, the material sensing optical fiber 54 is fixedly installed on the upper end of the positioning vertical plate 33 in the direction in which the product 1 is ejected. When all the products 1 in the contour cavity 21 are ejected, the material sensing optical fiber 54 can generate an alarm through the control module when it cannot sense the presence of the product 1.

[0055] See also Fig.10As shown, further, the present clip-type feeding device also includes a material box moving mechanism 6, which includes a material box moving cylinder 61 that is laterally fixedly connected to the positioning vertical plate 33 by bolts, a connecting block 62 that is fixedly connected to the guide rod of the material box moving cylinder 61 by bolts, and a material box 63 that is fixedly installed on the connecting block 62 by bolts. Two chambers are arranged in the material box 63, one chamber is used to place qualified products after processing, and the other chamber is used to place unqualified products after processing. In addition, after the material box 63 is moved above the product 1, it can also prevent cutting fluid and the like from entering the contoured clip 2.

[0056] The control module includes a manual valve 7 disposed on the bottom plate 1 , and the manual valve 7 can be operated to control the actions of the clip fixing cylinder 32 , the blowing device 4 , the blocking cylinder 52 , and the material box moving cylinder 61 .

[0057] The working process of the embodiment of the utility model is as follows:

[0058] In the initial state, the guide rod of the magazine moving cylinder 61 extends to move the magazine 63 to the side of the magazine positioning mechanism 3, the guide rod of the blocking cylinder 52 retracts to move the blocking block 53 to the outside of the contour cavity 21, and the guide rod of the magazine fixing cylinder 32 retracts;

[0059] The products 1 are manually put into the profiling cavity 21 of the profiling clip 2 in batches, and the profiling clip 2 carrying the products 1 is put into the clip positioning cavity 31 of the clip positioning mechanism 3 by means of the handle 28, and the positioning rod 36 is clamped in the clamping groove 341. At this time, the positioning rod 36 abuts against the profiling clip 2 to position and preliminarily fix the profiling clip 2. Then, the manual valve 7 can be operated (or other automatic control methods such as control buttons can be used) to extend the guide rod of the clip fixing cylinder 32 so that the guide rod is pressed against the profiling clip 2 to position and fix the profiling clip 2, and the guide rod of the blocking cylinder 52 is extended so that the blocking block 53 moves to the top of the profiling cavity 21, and the inflation device 4 is controlled to pass a certain amount of gas into the profiling cavity 21, so as to push the profiling slide block 22 up a certain distance, so that the top product 1 stacked on the profiling slide block 22 is ejected from the profiling cavity 21 and blocked by the blocking block 53, and the gripper installed on the CNC spindle grabs the profiling slide block 22. After taking the product 1, the guide rod of the blocking cylinder 52 is retracted so that the gripper can move the product 1 to the CNC clamping fixture; before the CNC spindle processes the product 1, the manual valve 7 is operated to retract the guide rod of the material box moving cylinder 61 to drive the material box 63 to move above the clip positioning mechanism 3, thereby preventing the cutting fluid and the like from entering the contour clip 2; after the product 1 is processed, the manual valve 7 is operated to move the material box 63 back to the side of the clip positioning mechanism 3, and the processed product 1 can be manually placed in the cavity of the material box 63 according to whether it is qualified; it should be noted that the above process can also be automatically controlled by the corresponding control module without setting the manual valve 7, as long as the above working process can be satisfied; after the product in the contour cavity 21 is ejected, the material sensing optical fiber 54 cannot sense the existence of the product 1, and an alarm is issued through the control module to remind the operator to place the product 1 in the contour cavity 21 again.

[0060] It should be noted that the connection method and control principle between the control module and the manual valve 7, the clip fixing cylinder 32, the blowing device 4, the blocking cylinder 52, the material sensing optical fiber 54, the material box moving cylinder 61, etc. are existing technologies and will not be repeated here. They are set up to improve the level of automation as long as they can meet the above-mentioned working process.

[0061] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
