Description

Technical Field

[0001] This utility model relates to the field of PCIE assembly equipment technology, and in particular to a PCIE grounding plate installation and feeding device. Background Technology

[0002] PCIe slots consist of a plastic base, pins, and a grounding tab. Since the grounding tab is a continuous strip, cutting and pressing it into the plastic base presents a challenge. Current cutting and pressing methods involve two separate cutting machines for the left and right grounding tabs. The operator presses a start button on one side of the grounding tab with their right hand, holds the product in their left hand, and inserts the cut grounding tab into the plastic slot with their right hand. The same process is repeated for the other side of the grounding tab, which is then placed in a transfer tray. This method is inefficient.

[0003] Patent No. CN201720200729.2 discloses an automatic cutting and pressing mechanism for grounding sheets, including a feeding unit, a cutting unit, a pre-pressing unit, a conveying unit, and a pressing unit. The feeding unit includes a material rack for placing rolled grounding sheets and a feeding cylinder for feeding the grounding sheets to the cutting unit. The cutting unit includes a base and a cutting cylinder. The cutting cylinder is connected to a cutting blade. The cutting cylinder drives the cutting blade to press down and cut the rolled grounding sheets. The cutting blade is equipped with a negative pressure device that can pick up the grounding sheets. The cutting cylinder moves the cut grounding sheets to a plastic seat on the flow channel and pre-presses them. The flow channel is equipped with a conveying unit that sends the plastic seat containing the grounding sheets to the pressing unit. The pressing unit includes a pressing cylinder. The method of adsorbing the grounding sheet by setting a negative pressure device on the cutting blade requires an additional vacuum generator and pipeline, which results in high equipment cost and high failure rate. Therefore, this utility model proposes a PCIE grounding sheet installation and feeding device. Utility Model Content

[0019] The present invention will be further described in detail below with reference to specific embodiments.

[0020] Example:

[0021] like Figures 1 to 5As shown, a PCIE grounding strip installation feeding device of this utility model includes a base and a pushing mechanism disposed on the base. The pushing mechanism includes a cylinder 1 and a first slide plate 2. A cutting mechanism is provided at the front end of the first slide plate 2. A grounding strip feeding mechanism for feeding material to the cutting mechanism is provided above the cutting mechanism. The cutting mechanism includes a first cutter 3 disposed at the lower end of the feeding mechanism and a second cutter 4 disposed at the front end of the first slide plate 2. The second cutter 4 is slidably connected to the first slide plate 2 along the width direction of the first slide plate 2. A clamping plate 5 is provided on the left side of the front end of the first slide plate 2 facing the second cutter 4. A linkage mechanism for driving the second cutter 4 to slide left and right is provided on the first slide plate 2. The cylinder 1 is connected to the linkage mechanism. The feeding mechanism feeds the grounding sheet material downwards until the bottom of the material reaches between the second cutter 4 and the clamping plate 5. The push rod of the cylinder 1 pushes forward, driving the second cutter 4 to slide to the left through the book-searching linkage mechanism. The side of the second cutter 4 cooperates with the clamping plate 5 to hold the grounding sheet. The second cutter 4 cooperates with the first cutter 3 to cut the grounding sheet. The cylinder 1 continues to advance, thereby pushing the first slide plate 2 to slide forward, thus pushing the cut grounding sheet to the designated work position. The push rod of the cylinder 1 retracts, and the linkage mechanism drives the second cutter 4 to slide to the right to release the grounding sheet. The cylinder 1 continues to retract, driving the first slide plate 2 to move the second cutter 4 back to its original position. This application can automatically realize the feeding, cutting and conveying of grounding sheet material. The second cutter 4 cooperates with the clamping plate 5 to clamp the grounding sheet, which replaces the existing equipment that uses a negative pressure device to suck up the grounding sheet, saving equipment costs and reducing equipment failure rate. When the cylinder 1 extends, the second cutter 4 is first driven to slide to the left by the linkage mechanism to cut off and clamp the grounding sheet. The cylinder 1 continues to extend and then sends the cut grounding sheet to the designated station. The cutting, clamping and conveying of the grounding sheet can be realized by a single cylinder 1, saving equipment costs.

[0022] The linkage mechanism includes a T-shaped slider 6. The first slide plate 2 has a first groove along its width direction. The horizontal portion of the T-shaped slider 6 is slidably connected within the first groove. The front end face of the first slide plate 2 has an opening for the vertical portion of the T-shaped slider 6 to extend out. The vertical portion of the T-shaped slider 6 extends through the opening and is connected to the second cutter 4. The upper end face of the first slide plate 2 has a second groove 8 along its length direction. A second slide plate 9 is slidably connected within the second groove 8. The cylinder 1 is connected to the second slide plate 9. The second slide plate 9 has an inclined first guide groove 10, which is inclined to the right. A first guide groove 10 is located at the middle of the upper end face of the horizontal portion of the T-shaped slider 6. A roller 11 is rotatably connected to a first guide groove 10. A second guide groove 12 and a third guide groove 13 are symmetrically provided on the second slide plate 9. Both the second guide groove 12 and the third guide groove 13 include a vertical portion along the length of the second slide plate 9. The opposite ends of the two vertical portions each have a right-leaning inclined portion. A third slide groove 14 and a fourth slide groove 15 are provided on the second slide plate 9 along its width. A second slider 16 and a third slider 17 are slidably connected within the third slide groove 14 and the fourth slide groove 15, respectively. A second roller 18 and a third roller 19 are respectively connected to the upper end faces of the second slider 16 and the third slider 17. The second roller 18 and the third roller 19 roll... The first slide plate 2 is movably connected within the second guide groove 12 and the third guide groove 13. A horizontally floating limiting block 20 is provided on the left side of the first slide plate 2. In the initial state, one end of the third slider 17 abuts against the rear side of the floating limiting block 20, and one end of the second slider 16 faces the right side of the floating limiting block 20. The second roller 18 is located at the end of the inclined portion of the second guide groove 12, and the third roller 19 is located at the end of the vertical portion of the third guide groove 13. The first roller 11 is located at the front end of the first guide groove 10. When the feeding mechanism feeds the grounding strip material between the second cutter 4 and the clamping plate 5, the cylinder 1 pushes the second slide plate 9 forward, and the third slider 17 is subjected to... With the floating limit block 20 blocking, the first slide plate 2 is temporarily fixed. When the second slide plate 9 moves forward, it drives the T-shaped block to slide to the left through the first guide groove 10 and the first roller 11, thereby causing the second cutter 4 to slide to the left. The side of the second cutter 4 cooperates with the clamping plate 5 to hold the grounding piece. The second cutter 4 cooperates with the first cutter 3 to cut the grounding piece off the material strip. During this process, the second roller 18 enters the vertical part from the cutting angle of the second guide groove 12. The second roller 18 cooperates with the inclined part of the second guide groove 12 to drive the second slider 16 to slide to the left a certain distance, thereby causing the second slider 16 to press the floating limit block 20 to the left a certain distance.The third roller 19 enters the inclined portion from the vertical portion of the third guide groove 13. The third roller 19 cooperates with the inclined portion of the third guide groove 13 to make the third slider 17 slide to the right. When the third roller 19 rolls to the end of the inclined portion of the third guide groove 13, the left end of the third slider 17 no longer abuts against the floating limit block 20. At this time, the grounding piece is just cut off. The cylinder 1 continues to push the second slide plate 9. The second slide plate 9 drives the first guard plate to slide forward, thereby pushing the cut-off grounding piece forward. The left end of the second slider 16 slides out of the side of the floating limit block 20. The floating limit block 20 is no longer pressed by the second slider 16 and resets. The left end of the second slider 16 extends to the front of the floating limit block 20. At this time, the grounding piece is sent to the designated work position. The cylinder 1 pulls back. When the second slide plate 9 is moved, the second slider 16 is blocked by the floating limit block 20, and the first slide plate 2 is temporarily fixed. When the second slide plate 9 slides backward, it drives the T-shaped block to slide to the right through the first guide groove 10 and the first roller 11, thereby causing the second cutter 4 to slide to the right, thus releasing the grounding piece. During this process, the third roller 19 and the inclined part of the third guide groove 13 cooperate to drive the third slider 17 to slide to the left and press the floating pressure block. The second roller 18 and the inclined part of the second guide groove 12 cooperate to drive the second slider 16 to slide to the right. The second slider 16 is no longer blocked by the floating pressure block. The second slide plate 9 is pulled backward, thereby causing the first slide plate 2 to slide backward, thus resetting the first slide plate 2 for subsequent work.

[0023] The feeding mechanism includes a reel with a grounding strip wound on it. The grounding strip has a positioning hole 21. A connecting block 22 is vertically positioned below the reel. A fourth guide groove 23 is vertically positioned on one side of the connecting block 22. A baffle 24 is positioned on one side of the fourth guide groove 23, forming a material guiding channel with the baffle 24. A ratchet 25 is positioned on the other side of the connecting block 22. Multiple teeth 26 are evenly distributed on the circumference of the ratchet 25. An opening communicating with the fourth guide groove 23 is provided on the side of the connecting block 22. The ratchet 25 extends into the fourth guide groove 23 through the opening and is driven by a servo motor. The grounding strip enters the fourth guide groove 23 from both above and below the reel. The teeth 26 on the ratchet 25 extend into the positioning hole 21 on the grounding strip. The servo motor drives the ratchet 25 to rotate, thereby driving the grounding strip downwards along the fourth guide groove 23.

[0024] The second cutter 4 has a positioning post 27 on its side, and the clamping plate 5 has a clearance hole that matches the positioning post 27. When the second cutter 4 clamps and cuts the grounding piece, the positioning post 27 passes through the positioning hole 21 on the grounding piece to position the grounding piece and ensure processing accuracy.

[0025] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
