When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0018] Please refer to Figures 1 to 12 , which is a claw - type automatic feeding feeder structure according to an embodiment of the present invention, including a feeder housing 10, a feeding assembly 20 installed on one side inside the feeder housing 10, a first clamping assembly 30 installed at the top on the other side inside the feeder housing 10, a second clamping assembly 40 installed below the first clamping assembly 30, and a scrap collection assembly 50 installed below the second clamping assembly 40. Among them, the first clamping assembly 30 and the second clamping assembly 40 are used to clamp the opposite ends of the sheet material 60 to achieve real - time tension adjustment of the tape 61. Specifically, the sheet material 60 includes a tape 61 designed in a sheet shape and a plurality of materials 62 evenly distributed on the tape 61.

[0019] The feeder housing 10 includes a first side plate 11 and a second side plate 12 arranged at intervals.

[0020] The feeding component 20 includes a lifting plate 21 that is liftably installed on the inner wall of the first side plate 11, a drawing frame 22 that is slidably connected to the inner wall of the second side plate 12, a material placing frame 23 that is detachably installed on the drawing frame 22, a material taking suction cup claw 24 that is slidably installed on the top of the feeder body 10, and a stripping plate 25 that is installed on one side of the top of the feeder body 10 away from the material placing frame 23. Among them, the material placing frame 23 is used for stacking sheet materials 60. Specifically, the lifting plate 21 is used to lift the sheet materials 60 inside the material placing frame 23 to the material taking height, and then the material taking suction cup claw 24 sucks the sheet materials 60 and moves them to the stripping plate 25 for stripping, that is, separating the material tape 61 from the material 62.

[0021] As Figure 2 and Figure 3 shown, the opposite ends of the material taking suction cup claw 24 are respectively connected to the top of the first side plate 11 and the top of the second side plate 12 through a material taking guide rail pair. One side of the material taking suction cup claw 24 is fixedly connected to a material taking belt driving module 26, so that the material taking suction cup claw 24 can move between the top of the material placing frame 23 and the top of the stripping plate 25. Among them, the material taking belt driving module 26 is installed on the outer wall of the second side plate 12.

[0022] In this embodiment, a lifting motor 211 is installed on the bottom surface of the lifting plate 21, and a gear 212 is connected to the rotor of the lifting motor 211; a rack 111 is installed on one side of the first side plate 11 corresponding to the gear 212, and the rack 111 is meshed with the gear 212. By the cooperative action of the rack 111, the gear 212 and the lifting motor 211, the lifting plate 21 can move up and down, thereby lifting the sheet materials 60 inside the material placing frame 23.

[0023] Further, a through groove 250 is provided in the middle of the stripping plate 25 along its length direction; the through groove 250 is located between two material taking guide rail pairs, and the through groove 250 is used for the first clamping component 30 to pass through.

[0024] The first clamping component 30 includes a horizontal moving block 31 that is respectively slidably connected to the inner wall of the first side plate 11 and the inner wall of the second side plate 12, a floating bracket 32 that is slidably connected to the horizontal moving block 31, a first clamping jaw 33 that is installed on the floating bracket 32, and a horizontal belt driving module 34 that is fixedly connected to one horizontal moving block 31; the horizontal belt driving module 34 is installed on the outer wall of the first side plate 11; the first clamping jaw 33 is used for clamping one end of the material tape 61 upward after passing through the through groove 250.

[0025] Specifically, as Figures 9 to 12As shown in the figure, the horizontal moving block 31 is slidably connected to the first side plate 11 and the second side plate 12 through the horizontal guide pair 311 respectively. Among them, a sunken recess 312 is provided at one end of the horizontal guide pair 311 close to the feeding assembly 20. The opposite sides of the floating bracket 32 are slidably connected to the horizontal moving block 31 through the vertical guide pair 321 respectively. The tops of the opposite sides of the floating bracket 32 are respectively provided with rollers 323 through a transfer shaft 322. The rollers 323 are slidably abutted against the guide rails of the horizontal guide pair 311, and the rollers 323 are also used for slidably engaging with the sunken recess 312.

[0026] During use, the horizontal belt drive module 34 drives the horizontal moving block 31, the floating bracket 32 and the first jaw 33 to move towards the feeding assembly 20 until the roller 323 is engaged with the sunken recess 312. At this time, since the horizontal moving block 31 is connected to the horizontal guide pair 311, that is, the height of the horizontal moving block 31 will not change, and the floating bracket 32 is connected to the horizontal moving block 31 through the vertical guide pair 321, the floating bracket 32 and the first jaw 33 sink along the vertical guide pair 321 under their own weights, that is, the height of the first jaw 33 drops to make room for the top space, facilitating the pick-up suction cup jaw 24 to transfer the sheet material 60 from the material placing rack 23 to the stripping plate 25. After the feeding is completed and the pick-up suction cup jaw 24 is reset, the horizontal belt drive module 34 moves in the reverse direction to drive the horizontal moving block 31, the floating bracket 32 and the first jaw 33 to move towards the stripping plate 25. The roller 323 moves out of the sunken recess 312, and the height of the first jaw 33 rises and passes through the through groove 250 and then moves close to the strip 61 and clamps one end of the strip 61.

[0027] The second clamping assembly 40 includes a second jaw 41 slidably installed below the first clamping assembly 30 and an inclined belt drive module 42 fixedly connected to one side of the second jaw 41; the inclined belt drive module 42 is installed on the outer wall of the second side plate 12. Specifically, the second jaw 41 is slidably connected to the first side plate 11 and the second side plate 12 through the inclined guide pair 411; the inclined guide pair 411 is arranged at an acute angle with the horizontal guide pair 311.

[0028] In use, the first clamping jaw 33 and the second clamping jaw 41 are used to clamp the opposite ends of the strip 61. During operation, fine adjustment can be performed respectively through the forward and reverse movements of the horizontal belt drive module 34 and the inclined belt drive module 42 according to the actual situation, and the pulling force on the strip 61, that is, the tension of the strip 61, can be adjusted in real time, so that the strip 61 is stably formed into a reverse fold at the end of the stripping plate 25. During this period, through the forward and reverse movements of the horizontal belt drive module 34 and the inclined belt drive module 42, the tension of the strip 61 is adjusted, and the elastic change of the strip 61 is compensated in real time, effectively reducing the tension fluctuation that is likely to occur during the feeding process, ensuring the feeding accuracy and stability, and further ensuring the efficiency and product quality of the entire mounting process. Then, due to the different material hardnesses of the strip 61 and the material 62, the material 62 is automatically peeled off at the reverse fold of the strip 61. When all the materials 62 on the strip 61 are peeled off, the first clamping jaw 33 releases the strip 61, and then the second clamping jaw 41 continues to pull the empty strip 61 to transport it into the waste collection assembly 50 for concentration.

[0029] The waste collection assembly 50 includes a waste collection hopper 51 located below the second clamping assembly 40 and a blowing nozzle 52 located above the waste collection hopper 51. Among them, the waste collection hopper 51 is located below the inclined guide rail pair 411, and the blowing nozzle 52 is located above the inclined guide rail pair 411. Further, the blowing port of the blowing nozzle 52 generally faces the middle position of the inclined guide rail pair 411, and the air flow generated by the blowing nozzle 52 is used to blow the strip 61 pulled by the second clamping jaw 41, so that the strip 61 can better fall into the waste collection hopper 51.

[0030] The above-mentioned claw-type automatic feeding feeder structure is simple in structure and convenient to use. The first clamping jaw 33 and the second clamping jaw 41 clamp the opposite ends of the strip 61. During operation, fine adjustment can be performed respectively through the forward and reverse movements of the horizontal belt drive module 34 and the inclined belt drive module 42 according to the actual situation, the tension of the strip 61 can be adjusted in real time, and the elastic change of the strip 61 can be compensated in real time, effectively reducing the tension fluctuation that is likely to occur during the feeding process, ensuring the feeding accuracy and stability, and further ensuring the efficiency and product quality of the entire mounting process.

[0031] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0032] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
