DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0030] See also Figure 1-8 ;

[0032] like Figure 2 and Figure 3 As shown, a feeding support seat 13 is provided below the feeding platform 11, and the feeding support seat 13 is used to support the feeding platform 11 and the feeding drive unit 12. A feeding track 14 is provided on the feeding platform 11 for the material belt to pass through, and the feeding drive unit 12 includes a horizontal feeding cylinder 15, a vertical feeding cylinder 16 and a feeding needle 17, wherein the horizontal feeding cylinder 15 is fixed on the feeding support seat 13 below the feeding platform 11, the vertical feeding cylinder 16 is drivingly connected to the horizontal feeding cylinder 15, and the feeding needle 17 is drivingly connected to the vertical feeding cylinder 16. It should be noted that when the material belt is located in the feeding track 14 and above the feeding needle 17 and the material belt needs to be moved, the vertical feeding cylinder 15 is used to drive the material belt to move. The cylinder 16 drives the feeding needle 17 to move upward and insert it into the material belt hole on the side of the material belt. The horizontal feeding cylinder 15 is started to drive the vertical feeding cylinder 16, the feeding needle 17 and the material belt inserted by the feeding needle 17 to move toward the adjusting device 2 until they move to the specified position. The vertical feeding cylinder 16 is then started to drive the feeding needle 17 to move downward and away from the material belt hole to release the material belt. Finally, the horizontal feeding cylinder 15 is started to drive the vertical feeding cylinder 16 and the feeding needle 17 to move and reset in the direction away from the adjusting device 2. During the whole process, the feeding device 1 realizes the feeding action of the material belt, and the feeding drive unit 12 continuously moves the material belt to the adjusting device 2.

[0033] For example Figure 4 and Figure 5 As shown, a rod support seat 23 is provided under the lever 21, one end of the lever 21 is rotatably connected to the rod support seat 23, and a first cross support rod 24, a second cross support rod 25, a first rotating wheel 26 and a second rotating wheel 27 are provided at both ends of the lever 21, the first rotating wheel 26 passes through the first cross support rod 24 and is rotatably connected to the lever 21, the second rotating wheel 27 passes through the second cross support rod 25 and is rotatably connected to the lever 21, the material belt comes out from the feeding device 1, passes over the first rotating wheel 26 and goes around under the second rotating wheel 27, and finally passes through the feeding table 31, the lever 21 takes the first cross support rod 24 as the rotation axis, and rotates clockwise or counterclockwise relative to the first cross support rod through the second rotating wheel 27 to adjust the length of the material belt located in the adjusting device 2, so as to adjust the tightness of the material belt located between the feeding device 1 and the feeding device 3.

[0034] Specifically, the sensor is fixedly arranged on the rod support seat 23, and the sensing part 22 includes an upper sensor 28 and a lower sensor 29. The upper sensor 28 is arranged in the upper area of ​​the lever 21, and the lower sensor 29 is arranged in the lower area of ​​the lever 21. When the material belt between the first rotating wheel 26 and the second rotating wheel 27 is longer, the material belt gradually loosens. At this time, one end of the lever 21 with the second rotating wheel 27 moves downward under the action of gravity until it moves to the sensing area of ​​the lower sensor 29 and is sensed. At this time, the lower sensor 29 will signal that the material belt is too long at the adjusting device 2. The information is transmitted to the equipment control area, the equipment control area receives the signal and sends a feeding signal to the feeding device 3, so that the feeding device 3 works; when the material belt between the first rotating wheel 26 and the second rotating wheel 27 is shorter, the material belt gradually becomes tense. At this time, one end of the lever 21 with the second rotating wheel 27 is lifted and moved upward until it moves to the sensing area of ​​the upper sensor 28 and is sensed. At this time, the upper sensor 28 transmits the information that the material belt is too short at the adjusting device 2 to the equipment control area, the equipment control area receives the signal and sends a feeding signal to the feeding device 1, so that the feeding device 1 works to move the material belt to the adjusting device 2.

[0035] like Figure 6 and Figure 7 As shown, a feed support seat 33 is provided below the feed platform 31, and the feed support seat 33 is used to support the feed platform 31 and the feed drive unit 32. A feed track 34 is provided on the feed platform 31 for the material belt to pass through, and the feed drive unit 32 includes a horizontal feed cylinder 35, a connecting plate 36, a slide rail 37, a vertical feed cylinder 38 and a feed needle 39, wherein the horizontal feed cylinder 35 is arranged on the feed platform 31, and the connecting plate 36 is arranged on the slide rail 37 and is connected to the feed needle 39. The horizontal feed cylinder 35 is telescopically connected, and the horizontal feed cylinder 35 is fixedly connected to the connecting plate 36. Starting the horizontal feed cylinder 35 can drive the connecting plate 36 and the vertical feed cylinder 38 to reciprocate along the slide rail 37. The feed needle 39 is telescopically connected to the vertical feed cylinder 38. Starting the vertical feed cylinder 38 makes the feed needle 39 move downward and insert into the material belt hole on the side of the material belt, or makes the feed needle 39 move upward and leave the material belt hole on the side of the material belt, thereby realizing the feeding action.

[0036] like Figure 7 and Figure 8As shown, a downward pressing cylinder 41, a downward pressing fixed block 42 and a downward pressing movable block 43 are provided on one side of the vertical feeding cylinder 38. The downward pressing fixed block 42 is fixedly arranged on the feeding platform 31, the downward pressing cylinder 41 is fixedly connected to the downward pressing fixed block 42, the downward pressing movable block 43 is telescopically connected to the downward pressing cylinder 41, and the lower end surface of the downward pressing movable block 43 is provided with two pressure strips 44 corresponding to the side position of the material belt. By starting the downward pressing cylinder 41, the downward pressing movable block 43 is driven to move downward so that the two pressure strips 44 press the side of the material belt, preventing the material belt located at the feeding device 3 from retreating toward the direction of the adjusting device 2, and avoiding the failure of the material belt in other steps at the next workstation of the feeding device 3 due to retreat, thereby effectively improving the feeding effect of the material belt and ensuring the normal operation of each workstation of the equipment.

[0037] Here’s how it works:

[0038] First, the continuous material belt is located between the feeding device 1, the adjusting device 2 and the feeding device 3 at the same time. At this time, the feeding device 1, the adjusting device 2 and the feeding device 3 feed and feed normally, and the length of the continuous material belt is neither too tight nor too loose.

[0039] When the continuous material belt is too tight, the lever 21 rotates upward counterclockwise and moves to the sensing area of ​​the upper sensor 28. The upper sensor 28 will sense the information transmission device control area. The control area controls the feeding device 1 to speed up the feeding speed, starts the vertical feeding cylinder 16, and the feeding needle 17 moves downward and inserts into the material belt hole. The horizontal feeding cylinder 15 starts, driving the vertical feeding cylinder 16, the feeding needle 17 and the material belt to move toward the adjusting device 2. By accelerating the feeding action of the material belt, the lever 21 rotates downward clockwise and away from the sensing area of ​​the upper sensor 28. The upper sensor 28 will not sense the information transmission device control area of ​​the lever 21, and the equipment control area will restore the feeding device 1 to a normal feeding speed.

[0040] When the continuous material belt is too loose, the lever 21 rotates downward clockwise to the sensing area of ​​the lower sensor 29. The lower sensor 29 will sense the information transmission device control area of ​​the lever 21. The control area controls the feeding device 1 to suspend feeding. At this time, the feeding device 3 feeds normally until the material belt at the adjusting device 2 gradually shortens. At this time, the lever 21 rotates upward counterclockwise away from the sensing area of ​​the lower sensor 29. The lower sensor 29 will not sense the information transmission device control area of ​​the lever 21. The control area controls the feeding device 1 to feed normally.

[0041] The utility model sets the induction of the feeding device 1 and the adjusting device 2 so that the swing setting of the lever 21 and the conveying rate of the feeding device 3 are coordinated, so that the material belt maintains a specific tension state, reduces the material belt conveying error, thereby improving the production efficiency of the chip inductor and reducing the production cost.
