Description

Technical Field

[0002] In the SMT industry, the packaging process of using high temperature tape to fix PCB flexible boards has significant advantages, including cost-effectiveness, easy operation, strength and reliability; these advantages make high temperature tape an indispensable material in the packaging and fixation of PCB flexible boards, and it is widely used in various industries and fields.

[0003] The existing high-temperature tape cutting mechanism only has the function of cutting the tape to a fixed length, and does not have the function of pressing the high-temperature tape before cutting or picking up the high-temperature tape after cutting. There are insufficient functions, resulting in poor use effect. As a result, the tape is easily caused to slip during the cutting process, affecting the cutting accuracy. At the same time, due to the lack of corresponding picking components, the tape is directly sucked up by suction claws after cutting. This method of directly using suction claws to suck up the tape may cause the tape to deform during the suction process, especially for thinner tapes. The deformation will affect subsequent packaging or use.

[0004] Therefore, a tape fixed-length cutting mechanism is urgently needed to solve the above problems.

[0025] Please refer to Figure 1 , Figure 3In one embodiment, the present application provides a tape fixed-length cutting mechanism, including a support plate 1, one side of the support plate 1 is rotatably connected to a placement disk 2, one side of the placement disk 2 is provided with a rotating shaft 3, one end of the rotating shaft 3 passes through the support plate 1 and is connected to a rotating component 5, a rotating block 4 is provided on the rotating shaft 3, the rotating block 4 is a regular polygon, a film picking component 6 is provided on the top of the rotating block 4, a clamping component 7 is provided on the bottom of the rotating block 4, a cutting component 8 is provided on the side of the rotating block 4 away from the placement disk 2, and a plurality of air avoidance grooves for avoiding the cutting component 8 are opened on the rotating block 4.

[0026] It can be understood that the present application provides a fixed-length cutting mechanism for tape, which places the tape on a placing plate 2, and uses the rotating component 5, the rotating block 4 and the cutting component 8 to cut the tape to a fixed length. The tape is pressed before cutting, which effectively prevents the tape from slipping during the cutting process, thereby affecting the cutting accuracy of the tape. Subsequently, the film picking component 6 is used to pick up the cut tape. Compared with directly using the suction claw to suck up the tape, it can play a transitional role, effectively reducing or avoiding deformation of the tape during the suction process and affecting the use of the tape.

[0027] For details, please refer to Figure 1 On the basis of the above embodiment, it also includes a guide component 9, which includes a fixed shaft and a guide wheel. At least one fixed shaft is arranged on the support plate 1 between the rotating shaft 3 and the placement disk 2, and a guide wheel is arranged on the fixed shaft. A guide groove is provided on the guide wheel. It can be understood that by setting the guide wheel, a guiding effect can be provided for the tape during the transmission process.

[0028] For details, please refer to Figure 1 On the basis of the above embodiment, a detection component 10 includes a mounting block and a sensor. The support plate 1 is provided with a mounting block on one side of the guide component 9, and the mounting block is provided with a sensor. It can be understood that the sensor is a photoelectric sensor. The photoelectric sensor determines whether the tape exists by emitting a light beam and detecting reflected light or transmitted light. When the tape exists, the light beam will be blocked or reflected by the tape, and the sensor will detect the signal change. Through the above settings, the tape can be monitored and replenished in time.

[0029] For details, please refer to Figure 4 On the basis of the above embodiment, the rotating assembly 5 includes a motor 501, a first transmission wheel, a second transmission wheel 502 and a belt 503. The motor 501 and the second transmission wheel 502 are arranged on the other side of the support plate 1. The output shaft of the motor 501 is connected to the first transmission wheel, and the first transmission wheel and the second transmission wheel 502 are connected by a belt 503. It can be understood that a servo motor is used to realize the precise rotation of the rotating block 4.

[0030] For details, please refer toFigure 1 , Figure 5 , on the basis of the above embodiments, the film picking assembly 6 includes a mounting plate 601, a first cylinder 602, a second cylinder 603 and a film picking tongue 604. The other side of the support plate 1 is provided with the mounting plate 601. The mounting plate 601 is provided with the first cylinder 602. The output end of the first cylinder 602 is connected with the second cylinder 603 through an adapter block. The output end of the second cylinder 603 is connected with the film picking tongue 604. It can be understood that the first cylinder 602 is a cylinder extending in the vertical direction, and the second cylinder 603 is a cylinder extending in the horizontal direction. By the mutual cooperation of the first cylinder 602 and the second cylinder 603, and with the film picking tongue 604, the cut tape can be picked up.

[0031] Specifically, please refer to Figure 1 , Figure 2 , on the basis of the above embodiments, the pressing assembly 7 includes a third cylinder 701 and a pressing block 702. The support plate 1 is provided with the third cylinder 701. The output end of the third cylinder 701 is provided with the pressing block 702. By providing the third cylinder 701 and the pressing block 702, the tape during the cutting process can be pressed to ensure that the tape can be firmly adhered to the rotating block 4.

[0032] Specifically, please refer to Figure 1 , Figure 2 , on the basis of the above embodiments, the cutting assembly 8 includes a fourth cylinder 801, a mounting seat 802 and a blade 803. The fourth cylinder 801 is inclinedly arranged on the support plate 1. The output end of the fourth cylinder 801 is provided with the mounting seat 802. The mounting seat 802 is provided with the blade 803. It can be understood that during the cutting process, the blade 803 enters the clearance groove to cut the tape, and at the same time avoids direct contact with the rotating block 4 to cause damage to the blade 803.

[0033] In summary, when a tape fixed-length cutting mechanism is in use, the tape is placed on the placing disk 2. The tape is pulled out, passed through the guiding groove, and then pasted on the rotating block 4, that is, the adhesive surface of the tape faces downward and winds around the rotating block 4. In this embodiment, the rotating block 4 is a regular octagon rotating block 4. The regular octagon rotating block 4 rotates clockwise by 45° each time. The third cylinder 701 extends to drive the pressing block 702 to press the tape. Subsequently, the fourth cylinder 801 extends to drive the blade 803 to cut the tape. When the completely cut tape rotates to a position close to the film picking tongue piece 604, the second cylinder 603 extends to drive the film picking tongue piece 604 to extend. Subsequently, the film picking tongue piece 604 is lifted by the first cylinder 602. Then, the tape is sucked away through the corresponding folding component (suction nozzle, suction claw). Through the above cyclic actions, the fixed-length cutting of the tape is realized. Compared with the traditional tape fixed-length cutting equipment, the tape fixed-length cutting mechanism provided by the present application fixes the tape before cutting by using the pressing component 7, effectively avoiding the slippage of the tape during the cutting process and affecting the cutting accuracy. At the same time, after cutting, the tape is lifted by the film picking component 6, playing a certain transitional role. Compared with directly sucking the cut tape by the suction claw, it can effectively reduce or avoid the deformation of the tape and improve the cutting quality.

[0034] It should be noted that in this article, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, device, article or method including a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, device, article or method.
