[0002] In insert molding or in-mold assembly processes, it is often necessary to precisely position a flexible material strip (such as a carrier tape with terminals) fed by a robot or automated equipment into a specific location in the mold cavity. During this process, the material strip's own flexibility, elastic deformation, or friction and interference with the mold surface may cause the material strip to not fully reach the predetermined position, resulting in positioning deviation, injection molding defects (such as incomplete encapsulation and overflow), stamping errors, and even mold damage.

[0031] The fixed roller 433 includes a fixed disk 4331, a support plate 4332, and a T-shaped plate 4333. The fixed disk 4331 is fixedly mounted on the rotating shaft 432. A plurality of support plates 4332 are fixedly mounted on both sides of the fixed disk 4331 in a circumferentially symmetrical manner. A sliding groove is provided between two adjacent support plates 4332. A plurality of T-shaped plates 4333 are fixedly mounted evenly on the fixed disk 4331 in a circumferential manner. The two ends of the T-shaped plates 4333 are respectively located at the output ends of the two support plates 4332.

[0032] The sliding roller 434 includes a sliding plate 4341, a connecting plate 4342, a T-shaped block 4343 and a second T-shaped plate 4344, wherein the sliding plate 4341 is slidably arranged on the rotating shaft 432, a plurality of connecting plates 4342 are fixedly arranged in a circumferential manner on the side of the sliding plate 4341 close to the fixed roller 433, and the connecting plates 4342 are slidably arranged along the sliding groove, a plurality of T-shaped blocks 4343 are fixedly arranged in a circumferentially symmetrical manner on both ends of the sliding plate 4341, and a second V-shaped T-shaped plate 4344 is fixedly arranged between two T-shaped blocks 4343 located at the same horizontal position;

[0033] The pressing mechanism 44 includes a fixed wheel 441, a lower pressure wheel 442, a sleeve 1 443, a sleeve 2 444, a slider 445 and a connecting shaft 446, wherein the sliders 445 are configured with two, the two sliders 445 are slidably set on the two vertical plates 42 and are driven by a hydraulic telescopic rod, a connecting shaft 446 is fixedly set between the two sliders 445, a fixed wheel 441 is fixedly set on the connecting shaft 446, and lower pressure wheels 442 are slidably set at both ends of the fixed wheel 441, the lower pressure wheel 442 is fixedly set with a sleeve 1 443, and a sleeve 2 444 is fixedly set on the slider 445, the sleeve 1 443 is sealingly and slidably connected to the sleeve 2 444, and a sliding cavity for the sealed sliding of the sleeve 1 443 is opened on the sleeve 2 444.

[0034] In particular, the lower pressure wheel 442 is made of flexible material, and the edge of the lower pressure wheel 442 is provided with an inclined surface with the same inclination as the T-shaped plate 4344, so that when the lower pressure wheel 442 is pressed down on the elastic sleeve 436 to clamp the material strip, the lower pressure wheel 442 will not cause damage to the material strip. In addition, the rotation of the connecting shaft 446 and the rotating shaft 432 and the rotation of the screw are all driven by an external drive motor.

[0035] During implementation, the thrust assembly 4 is used to push the material belt, thereby ensuring that the material belt is accurately positioned. First, the sliding roller 434 is adjusted to slide according to the width of the material belt, so that the T-plate 2 4344 slides along the T-slot 4361 and lifts the elastic sleeve 436, so that two limiting rings can be formed on the elastic sleeve 436, so that the material belt is always located between the two limiting rings during transportation to prevent the material belt from deviating. At the same time, according to the thickness of the material belt, the downward pressing mechanism 44 is adjusted to slide so that the elastic sleeve 436 and the lower pressing wheel 442 are respectively attached to the lower surface and upper surface of the material belt, and at this time the lower pressing wheel 442 does not completely cover the material belt. Subsequently, a detection device, such as a monitoring camera and a positioning sensor, can be set in the stamping die 2 to detect the conveying position of the material belt. When the conveying position of the material belt deviates, this The lower pressing wheel 442 is continuously driven to press down, so that the lower pressing wheel 442 and the elastic sleeve 436 completely clamp the material belt, and at the same time, the driving of the lower pressing wheel 442 and the elastic sleeve 436 to rotate is stopped, and the lead screw is driven to rotate, so that the vertical plate 42 drives the supporting mechanism 43 and the lower pressing mechanism 44 to slide, and at the same time pulls or pushes the material belt to slide, repositions the material belt to ensure its accurate position. During this process, the contact between the elastic sleeve 436 and the lower pressing wheel 442 and the material belt is always flexible contact, and the formation of the upper limit ring of the elastic sleeve 436 is to lift the elastic sleeve 436 itself, so the elastic sleeve 436 for limiting the material belt is also flexible, so it will not cause damage to the material belt, and it can achieve limiting and positioning functions for material belts of different thicknesses and widths, thereby ensuring that the conveying position of the material belt is completely accurate.

[0036] In this embodiment, Figure 6 and Figure 7 The T-shaped plate 1 4333 is provided with three connecting grooves 4334 , and the three connecting grooves 4334 are respectively located at three ends of the T-shaped plate 1 4333 ;

[0037] Three connecting rods 4345 are fixedly provided on the T-shaped block 4343 near the fixed roller 433 , and the three connecting rods 4345 are respectively slidably provided along the three connecting grooves 4334 ;

[0038] The adjusting roller 435 includes an adjusting seat 4351 and a third T-shaped plate 4352 , wherein the adjusting seat 4351 is fixedly disposed on the rotating disk 431 , and a plurality of third T-shaped plates 4352 are fixedly disposed on the adjusting seat 4351 in a circumferential manner;

[0039] The elastic sleeve 436 is provided with a plurality of T-slots 4361 in a circumferential pattern. The T-plate 1 4333 , the T-plate 2 4344 , the T-block 4343 and the T-plate 3 4352 can all be inserted into the T-slots 4361 , and the T-plate 2 4344 and the T-block 4343 can slide along the T-slots 4361 .

[0040] The adjusting seat 4351 is provided with a plurality of hydraulic chambers 4353 in a circumferential manner. The rotating disk 431 is provided with an annular chamber 437. The plurality of hydraulic chambers 4353 are in communication with the annular chamber 437. The vertical plate 42 is provided with an annular space for the annular chamber 437 to rotate in a sealed manner. The annular chamber 437 is connected to an external hydraulic drive mechanism via a hydraulic pipe. That is, when the rotating disk 431 rotates, the annular chamber 437 also rotates in a sealed manner along the annular space. Therefore, the rotation of the rotating disk 431 will not affect the hydraulic pressure provided by the annular chamber 437 to the hydraulic chamber 4353. In other words, the sliding of the sliding roller 434 is not affected by the rotation of the rotating disk 431 and the entire supporting mechanism 43.

[0041] A plurality of hydraulic rods 4346 are fixedly provided in a circle on one end of the sliding plate 4341 close to the adjustment seat 4351 . The hydraulic rods 4346 are sealed and slidably provided along the hydraulic cavity 4353 .

[0042] During implementation, the hydraulic pressure is used to drive the hydraulic rod 4346 to slide along the hydraulic chamber 4353, thereby driving the sliding roller 434 to slide along the fixed roller 433. During this process, the connecting plate 4342 will slide along the sliding groove, and the connecting rod 4345 will slide along the connecting groove 4334. Since the three connecting rods 4345 are located at the three ends of the T-shaped plate 4333, the three connecting rods 4345 will be stuck in the three ends of the connecting groove 4334 when sliding, thereby limiting the elastic sleeve 436 when the sliding roller 434 is separated from the fixed roller 433. That is, the connecting rod 4345 can be regarded as the internal rib of the elastic sleeve 436, and the connecting plate 4342 will support the inside of the elastic sleeve 436, thereby ensuring that no matter how the sliding roller 434 is curved, the elastic sleeve 436 can be The bearing capacity of roller 434 is not affected by the action of roller 434, that is, it always carries the material strip. At the same time, when the sliding roller 434 slides, the T-plate 2 4344 will slide along the T-slot 4361, and the T-plate 2 4344 will be V-shaped, and then during the sliding process, the T-plate 2 4344 will drive the elastic sleeve 436 to undergo elastic deformation, thereby forming two limiting rings on the elastic sleeve 436, and the elastic sleeve 436 that is not within the range of T-plate 2 4344 will not be deformed under the action of connecting rod 4345 and T-plate 1 4333, that is, only the elastic sleeve 436 within the range of T-plate 2 4344 will form a limiting ring, and the rest of the place will always remain flat, and at this time the elastic sleeve 436 is a whole, so there will be no limiting gap, that is, the material strip will not be stuck, ensuring the limitation while ensuring that the material strip is not damaged, and it is suitable for limiting material strips of various widths.

[0043] To sum up, when the present invention is implemented, the thrust assembly 4 is set to limit and push the material belt, ensuring that the position of the material belt is completely accurate during transportation, avoiding injection molding defects or stamping errors, and by setting a fixed roller 433 and a sliding roller 434 inside the elastic sleeve 436, the sliding of the sliding roller 434 enables the elastic sleeve 436 to form a limiting ring under the action of the T-plate 4344, and the elastic sleeve 436 is always a whole when the limiting ring is formed, thereby ensuring that the elastic sleeve 436 will not damage the material belt when limiting the material belt, and at the same time, for material belts of different thicknesses and widths, they can be limited and pushed by the sliding of the sliding roller 434 and the sliding of the pressing mechanism 44, so that the thrust assembly 4 has a wider range of application, and effectively improves the processing efficiency while ensuring the processing quality.

[0044] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
