The storage tank 41 is divided into two sections, namely a front end clamping area 412 and a rear end clamping area 411. The clamp 16 is initially placed vertically in the rear end clamping area 411 of the storage tank 41. Since there are too many clamps 16 stacked in the rear end clamping area 411, the rear end push plate 43 cannot completely push them, so the clamps 16 in the rear end clamping area 411 need to be pushed in batches to the front end clamping area 412, and the front end push plate 50 plays this role.

[0042] As shown in Figure 4 , the cutting and clamping mechanism mainly comprises a cutting and clamping cylinder 44, a sliding block 46 and a cutting plate 47, wherein the bottom of the sliding block 46 is slidably connected with a guide rail arranged on the frame 2, the cutting and clamping cylinder 44 is horizontally installed and fixed on the frame 2, and the output end of the cutting and clamping cylinder 44 is connected with the sliding block 46 through a connecting piece 45, the cutting plate 47 is vertically installed on the side surface of the sliding block 46, the moving direction of the cutting plate 47 is perpendicular to the moving direction of the clamps 16 in the storage tank 41, the sliding block 46 is controlled to move through the cutting and clamping cylinder 44, the cutting plate 47 is driven to cut into the front end of the storage tank 41, the clamp 16 closest to the clamping device 5 at the front end of the storage tank 41 is pushed into the clamping device 5, at this time, the feeding of the clamp 16 is completed, a dust cover 15 is arranged at the tail end of the cutting and clamping cylinder 44, used for protecting the transmission rod of the cylinder and playing a dustproof role.

[0043] It should be noted that a gap is left between the storage tank 41 and the clamping device 5, the size of the gap is matched with the thickness of the cutting plate 47, and the thickness of the cutting plate 47 does not exceed the thickness of the clamp 16, so that the cutting plate 47 can cut into the gap and just push the clamp 16 at the outermost side of the front end of the storage tank 41, without pushing other clamps 16.

[0044] As shown in Figure 5 and Figure 6As shown, the feeding device 3 is mainly composed of a pressing mechanism 31 and a magazine 32. A flat plate 7 is arranged on the frame 2, the pressing mechanism 31 is fixed on the flat plate 7, a plurality of vertical supporting rods 8 are arranged on the flat plate 7 away from the pressing mechanism 31, a supporting plate 9 is fixed on the top of the supporting rods 8, and the right end of the supporting plate 9 is close to the clamping device 5. A fixing seat 33 is arranged on the supporting plate 9 close to the pressing mechanism 31, a positioning cylinder 10 is installed on the side of the fixing seat 33, the output end of the positioning cylinder 10 is connected with a supporting plate 34, the two ends of the supporting plate 34 are provided with guide rods, one end of the guide rods is connected with the fixing seat 33 through a linear bearing and slides, a positioning pin 11 is arranged on the end of the guide rod, and the two ends of the two guide rods away from the positioning pin 11 are connected through a plate. When the magazine 32 is placed on the supporting plate 9, the two positioning pins 11 connected with the guide rods are inserted into the positioning holes in the front end of the magazine 32 through the positioning cylinder 10 to position and fix the magazine 32.

[0045] Reference Figure 5 The pressing mechanism 31 is mainly composed of a moving module 311, a sliding plate 312 and a plurality of push rods 313. The sliding plate 312 is drivingly connected with the moving module 311, the push rods 313 are horizontally fixed on the sliding plate 312, the length of the push rods 313 is greater than the length of the magazine 32, one end of the push rods 313 is connected with the fixing seat 33 through a linear bearing and slides, and penetrates into the magazine 32 through the fixing seat 33. A plurality of mobile phone frames 14 are vertically arranged in the magazine 32, a plurality of rod members are horizontally fixed in the magazine 32, the plurality of mobile phone frames 14 are arranged between the plurality of rod members, and the rod members play a role of limiting and guiding. The push rods 313 penetrate into the magazine 32 and abut against the mobile phone frames 14, the moving module 311 controls the movement of the push rods 313 to sequentially push out the mobile phone frames 14 in the magazine 32.

[0046] Reference Figure 8 A discharge plate 321 is arranged at the discharge end of the magazine 32 (i.e. the end close to the clamping device 5), a fourth limiting hole 3211 with a shape matching that of the mobile phone frame 14 is arranged on the discharge plate 321, and a plurality of round holes are arranged at several key positions of the fourth limiting hole 3211 so that the last mobile phone frame 14 is completely pushed out of the magazine 32 when the push rod 313 pushes it.

[0047] Reference Figure 7 A spring pressing sleeve 12 is further arranged on the sliding plate 312, a buffer spring 13 is arranged in the spring pressing sleeve 12, and the end of the push rod 313 is connected with the buffer spring 13. During the movement of the sliding plate 312 driving the push rod 313, the buffer spring 13 can play a role of buffering when the push rod 313 contacts with the mobile phone frames 14 in the magazine 32, so as to prevent the mobile phone frames 14 from being damaged due to too rapid movement of the push rod 313.

[0048] As Figure 9 and Figure 10 shown, the clamping device 5 is mainly composed of an inlet guide plate 51, a receiving plate 62, a positioning plate 54, a limiting plate 60, a cutting mechanism, a positioning mechanism 56, a material supporting mechanism 55, a pushing mechanism 63, etc. The inlet guide plate 51 is vertically fixed on the frame 2. The receiving plate 62 is arranged on the side of the inlet guide plate 51 close to the feeding device 3. The positioning plate 54 is arranged on the side of the inlet guide plate 51 close to the upper clamping device 4. Triangle plates 17 are arranged on both sides of the inlet guide plate 51 to strengthen the support of the inlet guide plate 51.

[0049] Referring to Figure 14 , a first limiting hole 621 is also arranged on the upper side of the receiving plate 62. The shape of the first limiting hole 621 is matched with the shape of the mobile phone frame 14. The fourth limiting hole 3211 on the discharge plate 321 of the magazine 32 is in connection with the first limiting hole 621 on the receiving plate 62. Two diagonal positioning pins 11 are arranged on the receiving plate 62. Two diagonal positioning holes are arranged on the discharge plate 321. The discharge plate 321 and the receiving plate 62 are accurately connected through the cooperation of the positioning pins 11 and the positioning holes. The front end of the magazine 32 is also positioned by the positioning pins 11 to ensure that the pushing direction of the inner frame 14 of the magazine 32 is on the same axis with the first limiting hole 621 on the receiving plate 62, so that the frame 14 can be smoothly pushed from the magazine 32 to the first limiting hole 621 on the receiving plate 62 by the push rod 313 one by one.

[0050] Referring to Figure 9 and Figure 13An inclined guide hole 511 is provided on the feed guide plate 51. The cutting mechanism consists of a cutting plate 61 and a cutting cylinder 53. A cylinder assembly plate 52 is provided on the side of the feed guide plate 51. The two ends of the cylinder assembly plate 52 are connected to the feed guide plate 51 through plates. The cutting cylinder 53 is inclinedly installed on the inner side of the cylinder assembly plate 52 (i.e., between the cylinder assembly plate 52 and the feed guide plate 51). The inclination of the cutting cylinder 53 is consistent with the inclination of the guide hole 511 on the feed guide plate 51. The cutting plate 61 is located in the guide hole 511 and is connected to the output end of the cutting cylinder 53. The cutting cylinder 53 controls the cutting plate 61 to move along the guide hole. 511 moves downward at an angle, wherein the bottom shape of the cutting plate 61 is adapted to the upper half of the third limiting hole on the clamp 16, and the lower side shape of the guide hole 511 on the feed guide plate 51 is adapted to the lower half of the third limiting hole on the clamp 16. When the cutting plate 61 moves downward to the lower side of the guide hole 511, the lower side of the cutting plate 61 and the lower side of the guide hole 511 will cooperate to form a complete limiting hole. The mobile phone frame 14 in the magazine 32 will be pushed to the lower side of the cutting plate 61 (i.e., into the guide hole 511 on the feed guide plate 51) by the push rod 313. After the frame 14 enters the guide hole 511, it will be lifted by the material support mechanism 55.

[0051] like Figure 11 As shown, the material support mechanism 55 is located below the cutting cylinder 53. It consists of a fixed bracket 551, a cylinder fixing component 552, a material support cylinder 553, and a material support component 554. The fixed bracket 551 protrudes outward in the middle to form a convex structure, so that the output end of the cutting cylinder 53 will not interfere with it when it moves. The cylinder fixing component 552 is fixed at an angle on the convex structure in the middle of the fixed bracket 551. The angle of inclination of the cylinder fixing component 552 is consistent with the angle of inclination of the cutting cylinder 53. The material support cylinder 553 is installed and fixed at the bottom of the cylinder fixing component 552. Thus, the material support cylinder 553 is also set at an angle. The material support component 554 is connected to the output end of the material support cylinder 553.

[0052] refer to Figure 15 The positioning plate 54 has a rectangular opening on its upper side to allow the output end of the cutting cylinder 53 to move. It also facilitates the material support cylinder 553 to control the material support component 554 to insert into the guide hole 511 on the feeding guide plate 51, thus supporting the mobile phone frame 14 that enters from the first limiting hole 621 on the receiving plate 62. When the frame 14 reaches the support component, the cutting cylinder 53 controls the cutting plate 61 to move down and contact the frame 14. At this time, the material support cylinder 553 controls the material support component 554 to retract, and the frame 14 will fall to the lower side of the guide hole 511. The cutting plate 61 moves down to position the mobile phone frame 14, which will be in the gap between the receiving plate 62 and the positioning plate 54.

[0053] like Figure 12As shown in the drawings, the positioning mechanism 56 is arranged on the lower side of the limiting plate 60, and is composed of a cylinder fixing plate 561, a positioning cylinder 10, a connecting plate 562, a first positioning piece 563 and a second positioning piece 564. The cylinder fixing plate 561 is vertically fixed on the top of the frame 2, and two triangular plates 17 are arranged on the side of the cylinder fixing plate 561 for strengthening support. The positioning cylinder 10 is horizontally fixed on the side of the cylinder fixing plate 561, and the output end of the positioning cylinder 10 is connected with the connecting plate 562 through the cylinder fixing plate 561. The two ends of the connecting plate 562 are slidably connected with the two ends of the cylinder fixing plate 561 through guide rods. The first positioning piece 563 is horizontally fixed on the middle of the connecting plate 562 for positioning the middle of the frame 14. Two second positioning pieces 564 are horizontally fixed on the two ends of the connecting plate 562 for positioning the corners of the two ends of the frame 14.

[0054] Referring to Figure 12 The first positioning piece 563 has two clamping pieces, and the middle part of the frame 14 is clamped between the two clamping pieces during positioning. The second positioning piece 564 has an opening similar to a right angle, and the corners of the two ends of the frame 14 are also similar to right angles. The corners of the two ends of the frame 14 are clamped in the opening of the second positioning piece 564 during positioning. The positioning cylinder 10 controls the first positioning piece 563 and the second positioning piece 564 to pass through the second limiting hole 541 of the positioning plate 54 and the limiting hole formed by the cutting plate 61 and the lower side of the guide hole 511 in sequence during positioning, and then the positioning is completed.

[0055] Referring to Figure 12 The material blocking mechanism is arranged on one side of the positioning mechanism 56 for blocking and positioning the clamp 16. The material blocking mechanism is composed of a mounting plate 57, a material blocking cylinder 58 and a material blocking piece 59. The mounting plate 57 is vertically fixed on one side of the cylinder fixing plate 561 and is perpendicular to the cylinder fixing plate 561. The material blocking cylinder 58 is horizontally fixed on the side of the mounting plate 57. The material blocking piece 59 is connected with the output end of the material blocking cylinder 58. The material blocking piece 59 has two protrusions on the side close to the limiting plate 60. The material blocking cylinder 58 controls the material blocking piece 59 to move forward, and the two protrusions on the material blocking piece 59 are inserted into the clamp cutting position between the positioning plate 54 and the limiting plate 60 to position the clamp 16. When the clamp 16 is pushed into the clamp cutting position by the cutting plate 47, the clamp 16 touches the two protrusions on the material blocking piece 59 and stops moving. At this time, the third limiting hole on the clamp 16 is just opposite to the second limiting hole 541 on the positioning plate 54, and waits for the frame 14 to be pushed into the third limiting hole on the clamp 16 by the material pushing mechanism 63.

[0056] Referring to Figure 12The pushing mechanism 63 is located below the support plate 9, which is composed of a bottom plate 631, a pushing cylinder 632, a pushing plate 633 and top rods 634. The bottom plate 631 is connected with the receiving plate 62 through a connecting rod. The pushing cylinder 632 is horizontally fixed on the bottom plate 631. The output end of the pushing cylinder 632 is connected with the pushing plate 633. The top rods 634 are horizontally fixed on the side of the pushing plate 633. The top rods 634 correspond to the two ends of the frame 14. The pushing cylinder 632 controls the movement of the top rods 634. The top rods 634 pass through the receiving plate 62 and abut against the frame 14 between the cutting plate 61 and the lower side of the guide hole 511. The frame 14 is pushed out of the guide hole 511 and passes through the second limiting hole 541 on the positioning plate 54 in turn and finally reaches the third limiting hole on the clamp 16 in the clamp cutting position. When the pushing cylinder 632 works, the positioning cylinder 10 also controls the first positioning member 563 and the second positioning member 564 to retreat. The two are matched to finally complete the clamping operation of the frame 14 and the clamp 16.

[0057] After the clamping is completed, the blocking cylinder 58 controls the blocking member 59 to retreat. At this time, the cutting plate 47 continues to push the clamp 16 carrying the frame 14 backward until the clamp 16 is pushed into the DDG processing device 1 from the inlet of the DDG processing device 1. The frame 14 on the clamp 16 is ground by the DDG processing device 1. After the grinding is completed, the clamp 16 is conveyed from the discharge port of the DDG processing device 1 to the unloading conveying line 6.

[0058] The above technical scheme only embodies the preferred technical scheme of the present application. Some changes made by the person skilled in the art to some parts of the present application also embody the principle of the present application and are within the protection scope of the present application.
