Description

Technical Field

[0001] This utility model relates to the field of punching machines, and more specifically, to a plastic carrier tape punching machine. Background Technology

[0002] Plastic carrier tapes are typically used as packaging products for electronic components. During processing, positioning holes for indexing and positioning are machined into the cavities on the surface of the plastic carrier tape to hold the electronic components.

[0003] A search revealed that Chinese Patent Publication No. CN220840531U discloses a "plastic carrier tape punching machine," which includes a worktable. A side plate is connected to the upper end of the worktable, and a base plate is screwed to the lower end. A punching mechanism is installed on the outer side of the side plate. A punching groove and a clamping mechanism are provided at the upper end of the worktable. Compared with existing technologies, this invention is highly practical, facilitating the discharge and collection of waste material after punching. It also allows for automatic up-and-down movement of the punching head, facilitating intermittent punching of the carrier tape and effectively improving the automated punching effect. Furthermore, it allows for quick adjustment of the distance between the two L-shaped plates according to the width of the carrier tape, facilitating rapid clamping of carrier tapes of different sizes. The guide wheels provide movable clamping on both sides of the carrier tape, preventing the need to loosen the clamp after each punching cycle and effectively improving work efficiency. However, it still has the following drawbacks:

[0004] (1) Existing plastic carrier tape punching machines intermittently drive the horizontal plate to move down and open positioning holes with fixed spacing in the transverse carrier tape. However, the rotation frequency of the existing rotary rod is fixed, so the spacing of the positioning holes punched on the carrier tape is fixed, and it is impossible to punch positioning holes with different spacings on the carrier tape, which increases the processing limitations of the punching machine.

[0005] (2) The diameter of the punch head of the existing punching machine is fixed, and the punch head is fixedly installed at the lower end of the lifting structure. Therefore, it can only punch out positioning holes of fixed size on the plastic carrier belt, which reduces the processing range of the punching machine.

[0006] Therefore, we made improvements and proposed a plastic carrier tape punching machine. Utility Model Content

[0007] The purpose of this invention is to address the problems of existing plastic carrier tape punching machines, which intermittently move the horizontal plate downwards with a rotating rod to create positioning holes with fixed spacing inside the horizontally moving carrier tape. However, the rotation frequency of the existing rotating rod is fixed, resulting in a fixed spacing of the positioning holes for punching the carrier tape, making it impossible to punch positioning holes with different spacings. Furthermore, the diameter of the punch head in existing punching machines is fixed, and since the punch head is fixedly installed at the lower end of the lifting structure, it can only punch positioning holes of a fixed size in the plastic carrier tape.

[0008] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0009] A plastic carrier tape punching machine is provided to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] Includes a base, the upper surface of which has a drive groove, a vertical plate is installed on the upper rear side of the base, a drive assembly is installed on the upper part of the vertical plate, and a drilling assembly is provided on the lower front side of the vertical plate.

[0012] The drive assembly includes a rotating rod disposed on the front side of the upper end of the upright plate, a connecting plate disposed on the outer wall of the front end of the rotating rod, a push roller rotatably disposed on the front side of the connecting plate away from the rotating rod, and a first motor connected to the rear end of the push roller through the connecting plate.

[0013] The drilling assembly includes front plates symmetrically installed on the lower front side of the upright plate, and a spring lifting plate slidably installed between the front plates. A slot is provided inside the front side of the spring lifting plate, and an insert plate is detachably inserted into the slot. A drilling rod is provided on the lower outer side of the insert plate.

[0014] As a preferred technical solution of this utility model, the rear end of the rotating rod is connected to a connecting roller, an outer plate is installed on the rear surface of the vertical plate on the upper side of the connecting roller, a sliding groove is opened inside the outer plate, a screw is arranged inside the sliding groove, a locking plate is fitted on the outer wall of the screw, and a second motor is connected to the upper end of the screw.

[0015] As a preferred technical solution of this utility model, the side wall of the slide groove is provided with a limiting groove, and the side wall of the locking plate is provided with a limiting plate that cooperates with the limiting groove.

[0016] As a preferred technical solution of this utility model, the insert plate has an inner groove on both sides, and an inner plate is movably disposed inside the inner groove.

[0017] As a preferred technical solution of this utility model, a card plate is provided on the outer side of the rear end of the inner plate, and card slots that cooperate with the card plate are opened on both sides of the slot.

[0018] As a preferred technical solution of this utility model, a pressure plate is provided on the outer wall of the inner plate away from the card plate, a telescopic rod is provided on the back of the pressure plate, and a spring is fitted on the outer wall of the telescopic rod.

[0019] As a preferred technical solution of this utility model, the grooves on the lower surface of the locking plate and the textures on the surface of the connecting roller cooperate with each other.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] In the solution of this utility model:

[0022] 1. By using a push roller, connecting roller, screw, locking plate, and limiting plate, when different interval punching operations are required, the second motor is controlled to rotate, driving the connected screw to rotate. This engages and drives the locking plate to move upward in the slide groove. Under the limiting plate's limitation in the limiting groove, the locking plate moves upward away from the surface of the connecting roller. The connecting roller is then controlled to rotate, driving the connected rotating rod to rotate. This allows push rollers of different sizes to rotate and approach the elastic lifting plate as needed. The second motor is then controlled to reverse, causing the screw to engage and drive the locking plate to move downward vertically. The locking plate is locked in place by the surface grooves of the connecting roller, ensuring the position of the push roller after rotation. The push roller is driven to rotate. When the long diameter end is vertical, it pushes the elastic lifting plate downward, driving the installed punching rod downward to achieve punching. When the short diameter end of the push roller is vertical, the elastic lifting plate loses its downward thrust and springs upward, causing the punching rod to move upward. During the continuous rotation of the push roller, the punching rod moves up and down reciprocally to achieve punching at the required intervals, improving the processing versatility of the punching machine.

[0023] 2. With the help of the insert plate, inner plate, clamping plate, pressure plate, telescopic rod, and spring, when punching holes of different diameters is required, press the two pressure plates in opposite directions to make them slide into the inner groove. This causes the clamping plate to disengage from the slot and slide into the inner groove. The telescopic rod and spring are squeezed to retract, and the insert plate is pulled forward to disengage from the slot. This allows for quick and easy removal of the punching rod. To replace the punching rod with the required diameter, insert the insert plate backward into the slot. Release the pressure on the pressure plate, and the telescopic rod and spring will push the inner plate outward, causing the clamping plate to insert into the aligned slot. This completes the quick replacement of the punching rod and improves the range of punching sizes. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0032] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] like Figure 1-5 As shown, this embodiment proposes a plastic carrier tape punching machine, including a base 1, a drive groove 2 is provided on the upper surface of the base 1, a vertical plate 3 is installed on the upper rear side of the base 1, a drive assembly is installed on the upper end of the vertical plate 3, and a punching assembly is provided on the front side of the lower end of the vertical plate 3.

[0036] The drive assembly includes a rotating rod 401 disposed on the front side of the upper end of the upright plate 3, a connecting plate 402 disposed on the outer wall of the front end of the rotating rod 401, a push roller 403 rotatably disposed on the front side of the connecting plate 402 away from the rotating rod 401, and a first motor 404 connected to the rear end of the push roller 403 through the connecting plate 402.

[0037] The drilling assembly includes a front plate 501 symmetrically mounted on the front side of the lower end of the upright plate 3. A spring lifting plate 502 is slidably mounted between the front plates 501. A slot 503 is provided inside the front side of the spring lifting plate 502. An insert plate 504 is detachably inserted into the slot 503. A drilling rod 505 is provided on the lower outer side of the insert plate 504.

[0038] like Figure 3 As shown, a connecting roller 405 is connected to the rear end of the rotating rod 401. An outer plate 406 is installed on the rear surface of the vertical plate 3 on the upper side of the connecting roller 405. A sliding groove 407 is opened inside the outer plate 406. A screw 408 is installed inside the sliding groove 407. A locking plate 410 is fitted on the outer wall of the screw 408. A second motor 409 is connected to the upper end of the screw 408. The screw 408 engages and drives the locking plate 410 to move vertically downward. The locking plate 410 is locked by the surface grooves of the connecting roller 405, thus ensuring the position of the pushing roller 403 after rotation.

[0039] like Figure 3 As shown, a limiting groove 411 is provided on the side wall of the slide 407, and a limiting plate 412 that cooperates with the limiting groove 411 is provided on the side wall of the locking plate 410. When the limiting plate 412 is embedded in the limiting groove 411, the locking plate 410 is disengaged from the surface of the connecting roller 405, and the connecting roller 405 is controlled to rotate, thereby driving the rotating rod 401 connected to it to rotate. Thus, different sizes of push rollers 403 can be selected to rotate and approach the elastic lifting plate 502 as needed.

[0040] like Figure 5 As shown, the insert plate 504 has an inner groove 506 on both sides. An inner plate 507 is movably installed inside the inner groove 506. When punching is required for different diameter sizes, the two pressure plates 510 are pressed in opposite directions to slide into the inner groove 506, which drives the clamping plate 508 to disengage from the clamping slot 509 and slide into the inner groove 506.

[0041] like Figure 5 As shown, a retaining plate 508 is provided on the outer rear end of the inner plate 507, and slots 509 that cooperate with the retaining plate 508 are provided on both sides of the slot 503. When the pressure on the pressure plate 510 is released, the telescopic rod 511 pushes the inner plate 507 outward elastically, causing the retaining plate 508 to be inserted into the aligned slots 509, thus completing the quick replacement of the punch rod 505.

[0042] like Figure 5As shown, a pressure plate 510 is provided on the outer wall of the inner plate 507 away from the card plate 508. A telescopic rod 511 is provided on the back of the pressure plate 510. A spring 512 is fitted on the outer wall of the telescopic rod 511. The telescopic rod 511 and the spring 512 are squeezed together to retract them. Pulling the insert plate 504 forward will disengage it from the slot 503, allowing the punching rod 505 to be quickly and individually removed. To replace the punching rod 505 with one of the required diameter, insert the insert plate 504 backward into the slot 503. Releasing the pressure on the pressure plate 510 will cause the telescopic rod 511 to push the inner plate 507 outward, causing the card plate 508 to be inserted into the aligned card slot 509.

[0043] like Figure 2 As shown, the grooves on the lower surface of the locking plate 410 cooperate with the textures on the surface of the connecting roller 405 to control the second motor 409 to reverse, causing the screw 408 to engage and drive the locking plate 410 to move vertically downwards, locking it by the grooves on its surface into the textures on the surface of the connecting roller 405.

[0044] Specifically, when using this punching machine: When punching operations at different intervals are required, the second motor 409 is controlled to rotate, driving the connected screw 408 to rotate. This engages and drives the locking plate 410 to move upward within the slide groove 407. Under the limiting position of the limiting plate 412 embedded in the limiting groove 411, the locking plate 410 is disengaged from the surface of the connecting roller 405. The connecting roller 405 is then controlled to rotate, driving the connected rotating rod 401 to rotate. This allows for the selection of different sized push rollers 403 to rotate as needed. When the elastic lifting plate 502 approaches, it controls the second motor 409 to reverse, causing the screw 408 to engage and drive the locking plate 410 to move downwards and vertically. The locking plates engage with the grooves on the surface of the connecting roller 405, locking it in place and ensuring the position of the rotating push roller 403. The push roller 403 is driven to rotate; when its long diameter end is vertical, it pushes the elastic lifting plate 502 downwards, causing the installed punching rod 505 to move downwards to perform punching. When the short diameter end of the push roller 403 is vertical, the elastic lifting plate 502... Plate 502 loses its downward thrust and springs upward, causing the punching rod 505 to move upward. As the push roller 403 rotates continuously, it drives the punching rod 505 to move up and down reciprocally, achieving the required punching interval and improving the processing versatility of the punching machine. When punching different diameter sizes is required, the two pressure plates 510 are pressed against each other, causing them to slide into the inner groove 506. This causes the clamping plate 508 to disengage from the clamping slot 509 and slide into the inner groove 506, thus affecting the telescopic rod 51. The spring 512 compresses the two, causing them to contract. Pulling the insert plate 504 forward disengages it from the slot 503, allowing for quick and easy removal of the punch rod 505. To replace the punch rod 505 with the required diameter, insert the insert plate 504 backward into the slot 503, release the pressure on the pressure plate 510, and the telescopic rod 511 and elastic spring push the inner plate 507 outward, causing the locking plate 508 to insert into the aligned locking slot 509. This completes the quick replacement of the punch rod 505, improving the range of punching sizes.

[0045] All technical features in this embodiment can be freely combined according to actual needs.

[0046] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
