Description

Technical Field

[0001] The utility model relates to the field of carrier tape production and processing equipment, in particular to a carrier tape pressing and flattening device. Background Technique

[0002] A carrier tape is a strip-shaped product applied in the field of electronic packaging, usually used for packaging electronic component products such as capacitors and resistors. Grooves for placing electronic components and positioning holes for indexing and positioning are equally spaced in its length direction. At present, during the processing of carrier tapes, the positioning holes are usually processed using punching equipment. During the punching process, if the carrier tape moves, it will affect the punching accuracy and efficiency of the carrier tape, and reduce the qualified rate of carrier tape punching; if the carrier tape is not flat when it is conveyed to the punching equipment, it will also affect the punching accuracy and efficiency of the carrier tape and reduce the qualified rate of carrier tape punching. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a carrier tape pressing and flattening device to ensure the flatness of the carrier tape during transportation before punching and prevent the carrier tape from moving during punching, thereby improving the punching accuracy, efficiency and qualified rate of the carrier tape.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] Provide a carrier tape pressing and flattening device, including a pressing mechanism and rolling and flattening units symmetrically arranged on both sides of the pressing mechanism. The pressing mechanism includes a driving unit and a pressing block unit connected to the driving unit. The pressing block unit is arranged above the moving path of the carrier tape. The driving unit can drive the pressing block unit to move downwards to press both sides of the carrier tape. The rolling and flattening unit is provided with at least one roller. The roller is arranged on the moving path of the carrier tape and is in rolling contact with the surface of the carrier tape.

[0006] The designed carrier tape pressing and flattening device of this scheme is located upstream of the carrier tape punching equipment. The rolling and flattening units are arranged on both sides of the conveying plate. When the carrier tape is conveyed on the conveying plate, the rollers are in rolling contact with both sides of the carrier tape on the conveying plate, so that both sides of the carrier tape are subjected to rolling extrusion by the rollers and then conveyed to the punching equipment, ensuring that both sides of the carrier tape are in a flat state. When the carrier tape is conveyed to the punching equipment, the driving unit drives the pressing block unit to move downwards to press both sides of the carrier tape, ensuring that the carrier tape does not shift during the punching extrusion process. Through the cooperation of the rolling and flattening unit and the pressing mechanism, the flatness of the surface of the carrier tape conveyed to the punching equipment and the stability of the punching process are ensured, thereby avoiding abnormalities during the carrier tape punching process and improving the punching accuracy, efficiency and qualified rate of the carrier tape.

[0007] Further, the pressing block unit includes a pressing arm connected to the output end of the driving unit, a first elastic member, and a pressing block elastically connected to the pressing arm through the first elastic member.

[0008] The pressing block is connected to the pressing arm through the first elastic member, so that the rigid pressure applied by the driving unit is transformed into a gradually changing pressure, avoiding the carrier tape being subjected to a large pressure resulting in indentations on its surface and causing product defects. At the same time, the contact between the pressing block and the carrier tape is a planar pressing contact rather than a spherical pressing contact, dispersing the pressure and further avoiding the carrier tape being subjected to a large pressure resulting in indentations on its surface.

[0009] Further, the number of the pressing blocks is at least two, and the pressing blocks are symmetrically arranged on both sides of the moving path of the carrier tape.

[0010] To ensure the balance of the pressure on both sides when the carrier tape is pressed and avoid the carrier tape being offset during punching due to only one side of the carrier tape being pressed, the number of the pressing blocks is at least two and they are symmetrically arranged on both sides of the moving path of the carrier tape.

[0011] Further, the material of the pressing block is rubber or silica gel.

[0012] The material of the pressing block is hard rubber or silica gel. When it is in pressing contact with the carrier tape, it has a certain elasticity and the four peripheral edges are smoothly transitioned, better protecting the carrier tape from generating indentations when being pressed.

[0013] Further, two rollers are provided, and the two rollers are symmetrically arranged on both sides of the moving path of the carrier tape and are located beside the pressing blocks.

[0014] The rollers are arranged on both sides of the moving path of the carrier tape. The width of the rollers is greater than the width of the two side edges of the carrier tape, which can ensure covering the two side edges of the carrier tape during rolling and squeezing, thereby ensuring the flatness of the carrier tape conveyed to the punching device.

[0015] Further, the rolling and flattening unit further includes mounting posts, second elastic members, a connecting plate elastically connected to the mounting posts through the second elastic members, and connecting rods connected to the connecting plate.

[0016] The rolling and flattening unit is fixed on the brackets on both sides of the conveying plate through the mounting posts. The rollers are installed at one end of the connecting rods, and the other end of the connecting rods is fixed on the connecting plate. The connecting plate is connected to the mounting posts through the second elastic members, and the compression deformation of the second elastic members causes the connecting plate to receive a rebounding force, thereby causing the rollers to press the carrier tape downward.

[0017] Further, the mounting posts are provided with mounting cavities, the second elastic members are placed in the mounting cavities, one end of the second elastic members is connected to the mounting posts, and the other end is connected to the connecting plate.

[0018] The mounting post is provided with a mounting cavity. The connecting plate is placed in the mounting cavity and connected to the mounting post through a second elastic member, and is in sliding contact with the peripheral side walls of the mounting cavity. The side walls of the mounting cavity play a guiding role to ensure that the elastic force received by the connecting plate is vertically downward.

[0019] Further, a bearing is sleeved on one end of the connecting rod away from the connecting plate, and the outer surface of the bearing is in contact with the roller.

[0020] The roller is sleeved on the connecting rod through the bearing so that the roller can roll smoothly. When the roller is forced to press down on the carrier tape and the carrier tape is conveyed, the roller and the carrier tape roll relative to each other instead of sliding, thereby avoiding scratching the surface of the carrier tape and causing defective carrier tape products.

[0021] Compared with the prior art, the beneficial effects of the present utility model are:

[0022] The pressing and flattening device designed in this solution is located upstream of the carrier tape punching device. The flattening unit is erected on both sides of the conveying plate. When the carrier tape is conveyed on the conveying plate, the roller rolls and contacts both sides of the carrier tape on the conveying plate, so that both sides of the carrier tape are rolled and squeezed by the roller and then conveyed to the punching device, ensuring that both sides of the carrier tape are in a flat state. When the carrier tape is conveyed to the punching device, the driving unit drives the pressing block unit to move downward to press both sides of the carrier tape, ensuring that the carrier tape does not shift during the punching and squeezing process. Through the cooperation of the flattening unit and the pressing mechanism, the flatness of the surface of the carrier tape conveyed to the punching device and the stability of the punching process are ensured, thereby avoiding abnormalities during the carrier tape punching process and improving the punching accuracy, efficiency and qualification rate of the carrier tape.

[0027] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present utility model are shown in the drawings. However, the present utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0028] As Figures 1 to 3 shown, a carrier tape pressing and flattening device is provided, which includes a pressing mechanism 1 and flattening units 2 symmetrically arranged on both sides of the pressing mechanism 1. The pressing mechanism 1 includes a driving unit 11 and a pressing block unit 12 connected to the driving unit 11. The pressing block unit 12 is arranged above the moving path of the carrier tape. The driving unit 11 can drive the pressing block unit 12 to move downward to press the two side edges of the carrier tape. The flattening unit 2 is provided with at least one roller 21. The roller 21 is arranged on the moving path of the carrier tape and is in rolling contact with the surface of the carrier tape.

[0029] The carrier tape pressing and flattening device designed in this solution is located upstream of the carrier tape punching device. The flattening units 2 are installed on both sides of the conveying plate. When the carrier tape is conveyed on the conveying plate, the rollers 21 are in rolling contact with the two sides of the carrier tape on the conveying plate, so that the two sides of the carrier tape are subjected to rolling extrusion by the rollers and then conveyed to the punching device, ensuring that the two sides of the carrier tape are in a flat state. When the carrier tape is conveyed to the punching device, the driving unit 11 drives the pressing block unit 12 to move downward to press the two side edges of the carrier tape, ensuring that the carrier tape does not shift during the punching extrusion process. Through the cooperation of the flattening unit 2 and the pressing mechanism 1, the flatness of the surface of the carrier tape conveyed to the punching device and the stability of the punching process are ensured, thereby avoiding abnormalities during the carrier tape punching process and improving the punching accuracy, efficiency and qualified rate of the carrier tape.

[0030] As Figure 1 and Figure 3As shown in the figure, the pressing block unit 12 includes a pressing arm 121 connected to the output end of the driving unit 11, a first elastic member 122, and a pressing block 123 elastically connected to the pressing arm 121 through the first elastic member 122. The number of pressing blocks 123 is at least two, and the pressing blocks 123 are symmetrically arranged on both sides of the moving path of the carrier tape. In this embodiment, four pressing blocks 123 are arranged in an array, and the pressing blocks 123 are made of hard rubber or silica gel. The pressing arm 121 has an I-shaped structure, and connecting columns protrude downward from its four ends. The connecting columns are connected to the pressing blocks 123 through the first elastic member 122, and the first elastic member can be a spring. The pressing block 123 and the pressing arm 121 are connected through the first elastic member 122, so that the rigid pressure applied by the driving unit 11 is transformed into a gradually changing pressure, avoiding the carrier tape being subjected to a large pressure resulting in indentations on its surface and causing product defects. At the same time, the pressing block 123 and the carrier tape are in planar pressing contact, rather than spherical pressing contact, which disperses the pressure and further avoids the carrier tape being subjected to a large pressure resulting in indentations on its surface. In order to ensure the balance of the pressure on both sides when the carrier tape is pressed, and to avoid the carrier tape offsetting during punching due to only one side of the carrier tape being pressed, the number of pressing blocks 123 is at least two and they are symmetrically arranged on both sides of the moving path of the carrier tape. The pressing blocks 123 are made of hard rubber or silica gel, which has a certain elasticity when in pressing contact with the carrier tape, and the four peripheral edges are smoothly transitioned, better protecting the carrier tape from generating indentations when pressed.

[0031] As Figure 1 and Figure 2 shown in the figure, the flattening unit 2 further includes a mounting post 22, a second elastic member 23, a connecting plate 24 elastically connected to the mounting post 22 through the second elastic member 23, and a connecting rod 25 connected to the connecting plate 24. The flattening unit 2 is fixed on the brackets on both sides of the conveying plate through the mounting post 22. The roller 21 is installed at one end of the connecting rod 25, and the other end of the connecting rod 25 is fixed to the connecting plate 24. The connecting plate 24 and the mounting post 22 are connected through the second elastic member 23, and the second elastic member 23 is compressed and deformed so that the connecting plate 24 receives a rebounding force, thereby causing the roller 21 to press the carrier tape downward. The second elastic member 23 can be a spring. The mounting post 22 is provided with a mounting cavity 221, the second elastic member 23 is placed in the mounting cavity 221, one end of the second elastic member 23 is connected to the mounting post 22, and the other end is connected to the connecting plate 24. The connecting plate 24 is placed in the mounting cavity 221 and is connected to the mounting post 22 through the second elastic member 23, and is in sliding contact with the peripheral side walls of the mounting cavity 221. The side walls of the mounting cavity 221 play a guiding role to ensure that the rebounding force received by the connecting plate 24 is all vertically downward.

[0032] As Figure 1As shown in the figure, two rollers 21 are provided. The two rollers 21 are symmetrically arranged on both sides of the moving path of the carrier tape and are located beside the pressing block 123. The width of the roller 21 is greater than the width of both edges of the carrier tape, so that when rolling and squeezing, it can ensure that both edges of the carrier tape are covered, thereby ensuring the flatness of the carrier tape conveyed to the punching device. One end of the connecting rod 25 away from the connecting plate 24 is sleeved with a bearing 251, and the roller 21 is sleeved on the connecting rod 25 through the bearing 251, so that the roller 21 can roll smoothly. When the roller 21 is forced to press the carrier tape downward and the carrier tape is conveyed, the relative movement between the roller 21 and the carrier tape is rolling rather than sliding, thus avoiding scratching the surface of the carrier tape and causing defective carrier tape products. Additionally, the roller 21 can also be in the form of a long cylindrical roller. A long cylindrical roller spanning the conveying plate is provided, and its two ends are respectively connected to the connecting rods 25 on both sides of the conveying plate.
