Description

Technical Field

[0001] This invention relates to the field of carrier tape processing equipment technology, and in particular to a precision punching device for carrier tape. Background Technology

[0002] Carrier tape is a widely used strip-shaped packaging material in the electronics manufacturing industry, primarily used in the electronic component placement industry. The carrier tape has a specific thickness and features evenly distributed holes along its length for holding electronic components and positioning holes for indexing. The holes hold the electronic components, while the positioning holes ensure precise positioning by automated placement equipment. The carrier tape is used in conjunction with a cover tape; sealing the cover tape over the carrier tape creates a closed package, protecting the electronic components from contamination and damage during transportation.

[0003] To ensure accurate mounting of electronic components, the holes and positioning holes on the carrier tape must have high dimensional accuracy. Ordinary electronic punching equipment will experience significant increases in dimensional error over long-term production, leading to a gradual increase in the defect rate and seriously affecting production efficiency and costs; while high-precision punching equipment is expensive, which will significantly increase production costs.

[0029] like Figure 1-7 As shown, a precision punching device for a carrier belt includes a worktable 1. A spindle 2, a punching mechanism 3, and a pulling plate mechanism 4 are connected to the worktable 1. A first disc cam 5, a second disc cam 6, and an end face cam 7 are connected to the spindle 2. The punching mechanism 3 includes a first drive rod 3.1 and a first positioning shaft 3.2. The first positioning shaft 3.2 rotatably passes through the middle of the first drive rod 3.1. One end of the first drive rod 3.1 abuts against the side of the second disc cam 6, and the other end of the first drive rod 3.1 is a drive end 3.1.1. The pulling plate mechanism 4 includes a reciprocating shaft 4.1 movably connected to the worktable 1, and a connecting rod on the reciprocating shaft 4.1. The pull plate 4.2 and the second drive rod 4.3 are rotatably connected to the worktable 1. The second drive rod 4.3 has a second positioning shaft 1.1 rotatably passing through its middle part. The second positioning shaft 1.1 is set on the worktable 1. One end of the second drive rod 4.3 abuts against the end face of the end face cam 7. The other end of the second drive rod 4.3 is connected to the reciprocating shaft 4.1. The reciprocating shaft 4.1 passes through the middle part of the pull plate 4.2. One side of the pull plate 4.2 is connected to an abutment 8. The other side of the pull plate 4.2 is a gripping part 4.2.1. The abutment 8 is rotatably connected to the worktable 1 and abuts against the side of the first disc cam 5.

[0030] This invention achieves this by having one end of the first drive rod 3.1 abut against the side of the second disc cam 6, causing the first drive rod 3.1 to reciprocate with the rotation of the second disc cam 6; by having the pull plate 4.2 connected to the abutment 8, which abuts against the side of the first disc cam 5, causing the pull plate 4.2 to reciprocate with the rotation of the first disc cam 5; and by having one end of the second drive rod 4.3 abut against the end face of the end face cam 7, causing the second drive rod 4.3 to reciprocate with the rotation of the end face cam 7. The direction is perpendicular to the abutment 8, thereby driving the reciprocating shaft 4.1 and the pull plate 4.2 to reciprocate in another direction. The present invention drives the first drive rod 3.1 and the pull plate 4.2 to reciprocate by setting the first disc cam 5, the second disc cam 6 and the end face cam 7. The movement range of the first drive rod 3.1 and the pull plate 4.2 is determined by the external dimensions of the first disc cam 5, the second disc cam 6 and the end face cam 7, which is not easily changed in long-term use, thereby ensuring that the present invention can maintain accuracy and stability in long-term operation.

[0031] Preferably, the abutment 8 includes a floating platform 8.1 rotatably connected to the worktable 1. The floating platform 8.1 is disposed below the first disc cam 5. A first abutment bearing 8.2 is rotatably connected to the upper side of the floating platform 8.1, and the first abutment bearing 8.2 abuts against the side of the first disc cam 5. A floating platform spring 8.3 is connected to the lower side of the floating platform 8.1. One end of the floating platform spring 8.3 abuts against the floating platform 8.1, and the other end abuts against the worktable 1. By setting the floating platform spring 8.3 to push the floating platform 8.1, the first abutment bearing 8.2 on the floating platform 8.1 can always be in close contact with the side of the first disc cam 5. By setting the first abutment bearing 8.2 to abut against the side of the first disc cam 5, the frictional force when the abutment 8 and the first disc cam 5 are engaged is reduced, preventing wear of the first disc cam 5 that would lead to a decrease in the production accuracy of the present invention.

[0032] Preferably, a connecting shaft 8.4 is connected to the floating platform 8.1, and the connecting shaft 8.4 is movably inserted into a connecting hole 4.2.2 at one end of the pull plate 4.2. When the floating platform 8.1 moves, it drives the connecting shaft 8.4 to move, and the moving connecting shaft 8.4 drives the pull plate 4.2 to rotate up and down.

[0033] Preferably, the connecting shaft 8.4 includes an end 8.4.1 with a slot, a fixed rod 8.4.2 coaxially connected to the end 8.4.1, and a support rod 8.4.3 eccentrically connected to the fixed rod 8.4.2. The end 8.4.1, the fixed rod 8.4.2, and the support rod 8.4.3 are connected in sequence, and the support rod 8.4.3 is movably inserted into the connecting hole 4.2.2. The end cap 8.4.1 allows the user to easily rotate the connecting shaft 8.4. The fixed rod 8.4.2 connects the floating platform 8.1 and the support rod 8.4.3. When the user rotates the end cap 8.4.1, it causes the fixed rod 8.4.2 and the support rod 8.4.3 to rotate together. Because the fixed rod 8.4.2 and the support rod 8.4.3 are eccentrically connected, the position of the support rod 8.4.3 will shift, thereby moving the pull plate 4.2 and changing its working path. This design allows the user to easily adjust the movement path of the pull plate 4.2 according to production needs.

[0034] Preferably, the floating platform 8.1 is provided with two clamping plates 8.1.1, and the fixing rod 8.4.2 is engaged between the two clamping plates 8.1.1. Each clamping plate 8.1.1 has a locking groove 8.1.2 for the fixing rod 8.4.2 to engage. The fixing rod 8.4.2 is secured by the clamping plates 8.1.1, allowing the user to adjust the clamping tightness of the clamping plates 8.1.1 to change the fixation strength of the fixing rod 8.4.2. Preferably, the two clamping plates 8.1.1 are connected by bolts to facilitate user adjustment of the clamping tightness of the clamping plates 8.1.1.

[0035] Preferably, one end of the second drive rod 4.3 is rotatably connected to a second abutment bearing 4.3.1, which abuts against the end face of the end face cam 7. By setting the second abutment bearing 4.3.1 to abut against the end face of the end face cam 7, the frictional force when the second drive rod 4.3 and the end face cam 7 are engaged is reduced, preventing wear of the end face cam 7 from causing a decrease in the production accuracy of the present invention. Preferably, the other end of the second drive rod 4.3 is connected to a tension spring that drives the second abutment bearing 4.3.1 to press against the end face cam 7. One end of the tension spring connected to the second drive rod 4.3 is connected to the end of the second drive rod 4.3 away from the end face cam 7, and the other end of the tension spring connected to the second drive rod 4.3 is connected to the worktable 1.

[0036] Preferably, one end of the first drive rod 3.1 is rotatably connected to a third abutment bearing 3.1.2, which abuts against the end face of the second disc cam 6. By setting the third abutment bearing 3.1.2 to abut against the end face of the second disc cam 6, the frictional force when the first drive rod 3.1 and the second disc cam 6 are engaged is reduced, preventing wear of the second disc cam 6 from causing a decrease in the production accuracy of the present invention. Preferably, the first drive rod 3.1 is positioned above the second disc cam 6. Preferably, the other end of the first drive rod 3.1 is connected to a spring that drives the third abutment bearing 3.1.2 to press against the second disc cam 6. One end of the spring connected to the first drive rod 3.1 abuts against the end of the first drive rod 3.1 near the second disc cam 6, and the other end of the spring connected to the first drive rod 3.1 abuts against the worktable 1.

[0037] Preferably, the worktable 1 is provided with two first positioning plates 1.2. The reciprocating shaft 4.1 is rotatably and slidably inserted through the first positioning plates 1.2. The two ends of the first positioning shaft 3.2 are respectively rotatably connected to one of the first positioning plates 1.2, thereby realizing the rotation and sliding function of the reciprocating shaft 4.1, so that the pull plate 4.2 connected to the reciprocating shaft 4.1 can rotate and slide back and forth, and at the same time, the first positioning shaft 3.2 can rotate.

[0038] Preferably, the worktable 1 is provided with two second positioning plates 1.3, and the two ends of the spindle 2 are respectively rotatably connected to one of the second positioning plates 1.3, thereby realizing the positioning and rotation of the spindle 2.

[0039] Preferably, the worktable 1 is connected to a drive motor 9, the output end of which is connected to a first synchronous pulley 9.1, and the main shaft 2 is connected to a second synchronous pulley 2.1. The first synchronous pulley 9.1 and the second synchronous pulley 2.1 are connected by a synchronous belt 10. The synchronous belt connection has an accurate transmission ratio and high transmission efficiency, ensuring stable operation of the invention. Simultaneously, the synchronous belt 10 also has a certain shock absorption capacity, and since the carrier belt product is relatively light and easily affected by vibration, using the synchronous belt 10 can reduce the impact of vibration on production and processing.

[0040] Preferably, the driving end 3.1.1 of the first driving rod 3.1 is connected to a punching head through a crank-slider mechanism, so as to convert the rotation of the first driving rod 3.1 into the up-and-down sliding of the punching head.

[0041] The working process of this invention is as follows: After the drive motor 9 is started, the first synchronous pulley 9.1 drives the second synchronous pulley 2.1 to rotate through the synchronous belt 10, thereby driving the main shaft 2 to rotate; the first disc cam 5, the second disc cam 6, and the end face cam 7 connected to the main shaft 2 rotate with the main shaft 2; the second disc cam 6 drives the first drive rod 3.1 to reciprocate; by connecting a punching head to the drive end 3.1.1 of the first drive rod 3.1, the punching head can be made to move back and forth accurately at a fixed rhythm to achieve punching. The hole function is as follows: The first disc cam 5 rotates to drive the abutment 8 to reciprocate, thereby driving the pull plate 4.2 to reciprocate, so that the gripping part 4.2.1 on the pull plate 4.2 flips back and forth to repeatedly press and release the carrier belt; The end face cam 7 rotates to drive the second drive rod 4.3 to reciprocate, the second drive rod 4.3 drives the reciprocating shaft 4.1 to move back and forth, the reciprocating shaft 4.1 drives the pull plate 4.2 to move back and forth, so that the gripping part 4.2.1 can move the carrier belt when pressing the carrier belt and reset when releasing the carrier belt.

[0042] In this invention, the drive end 3.1.1 and the gripping part 4.2.1 work synchronously and in conjunction. The movement trajectory of the drive end 3.1.1 and the gripping part 4.2.1 is determined by the mechanical structure of the first disc cam 5, the second disc cam 6 and the end face cam 7, and is not affected by the drive motor 9, so as to ensure that the present invention can accurately punch the carrier belt in a long-term and stable manner.

[0043] Preferably, the bottom surface of the gripping part 4.2.1 is provided with a claw, which is used to insert into the holes or positioning holes on the carrier tape, so that the gripping part 4.2.1 can move the carrier tape accurately and stably.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
