Description

Technical Field

[0001] The present invention belongs to the technical field of carrier tape processing, and particularly relates to an ultra-precision flat-type carrier tape forming machine. Background Art

[0002] A carrier tape is a strip-shaped product applied in the field of electronic packaging. It has a specific thickness, and on its length direction, there are evenly distributed part receiving grooves for placing electronic components and positioning holes for indexing and positioning.

[0003] With the development of the electronic market, various electronic components tend to be smaller and more precise, having higher standards for the processing technology and cleanliness of carrier tapes. Even some precision electronic components have clear requirements for the antistatic level of carrier tapes. For the different needs of different customers, different carrier tape raw materials are used, mainly including two categories: plastic carrier tapes and paper carrier tapes. Currently, the main materials of plastic carrier tapes in the market are PC (polycarbonate), PS (polystyrene), and ABS (Acrylonitrile Butadiene Styrene plastic). According to the requirements of different electronic components, corresponding molds are processed and different carrier tape raw materials are used.

[0004] Currently, the carrier tape forming machines on the market are divided into two categories. One is the roller-type carrier tape forming machine. This type of forming machine can produce precision carrier tapes with accurate control of dimensions. However, during the rolling forming process, the overall raw material is heated, which will cause the bending degree of the carrier tape to be too severe. There are also problems such as difficult demolding for some special-shaped or deeper molds, poor forming, too thin bottom, and insufficient strength. The other is the flat-type carrier tape forming machine. This type of forming machine is slower than the roller-type forming machine, but it is very friendly to some parts with too large dimensions. Through local heating for forming, it can better avoid the bending and deformation of the carrier tape. However, the existing problems are that the stroke controls of the existing flat-type carrier tape forming machines are generally achieved through separate pneumatic controls, resulting in weaker precision control of the flat-type carrier tape forming machine than that of the roller-type carrier tape forming machine, and low efficiency, unable to meet the high-precision requirements of customers.

[0024] Advantages and positive effects of the present invention:

[0025] 1. The driving of the heating mechanism, the groove forming mechanism and the punching mechanism of the present invention adopts an up-and-down main shaft synchronous transmission mechanism driven by a single servo. A heating upper cam, a forming upper cam and a punching upper cam are fixed on the upper main shaft. A heating lower cam and a forming lower cam are successively fixed on the lower main shaft from front to back. Through the cooperation of the cam and the cam contact roller at the corresponding position, during the stop period of the carrier tape, local heating of the forming part of the carrier tape can be realized at three consecutive positions, namely the front, middle and rear positions on the carrier tape, by the upper heating die module and the lower heating die module. The part receiving groove is punched on the carrier tape at the previous heating point by the upper forming die module and the lower forming die module, and the indexing positioning hole is punched on one side of the part receiving groove. The small holes at the bottom of the part receiving groove are punched by the upper punching die module and the lower punching die module. Compared with the existing pneumatic driving mode of independent control, this driving mode has high motion precision, greatly improves the quality of forming and punching, is especially suitable for high-speed production, and can greatly improve the production efficiency.

[0026] 2. The present invention uses a single motor to link the heating mechanism, the forming mechanism, and the punching mechanism, ensuring precise coordination among the mechanisms. The heating mechanism heats the forming part of the component receiving groove to be formed on the carrier tape by means of point contact. By comparing with the carrier tape after overall heating, it can be known that the point contact heating can preferably avoid the bending deformation of the carrier tape due to heating, ensuring the flatness of the carrier tape during forming. The flatness of the carrier tape is an important parameter of the carrier tape quality. Only with better flatness can the accurate positioning of electronic devices in the component receiving groove and the complete film covering on the upper surface of the component receiving groove be ensured. The accurate positioning of electronic devices in the component receiving groove can ensure accurate grasping by the manipulator during subsequent production.

[0027] 3. In the existing carrier tape forming machine, the indexing positioning holes are punched after the component receiving grooves are formed. The existing processing method cannot accurately ensure the dimensions between the indexing positioning holes and the component receiving grooves, and can only be controlled within the required range as much as possible. However, in the present invention, the forming of the component receiving grooves and the punching of the indexing positioning holes are designed in one mechanism, realizing the simultaneous processing of the component receiving grooves and the indexing positioning holes, and strictly controlling the dimensional accuracy between the indexing positioning holes and the component receiving grooves through die processing.

[0028] 4. The present invention provides a separate punching mechanism after the groove forming mechanism for punching small holes in the middle of the bottom of the component receiving grooves, aiming to be applicable to the processing of ultra-small component receiving grooves. When punching ultra-small component receiving grooves, since the distance between the component receiving grooves is close, it is difficult to arrange the punching pins in one mechanism. The present invention divides the punching into the groove forming mechanism and the punching mechanism, and generates them simultaneously during processing, which can preferably meet the processing of ultra-small component receiving grooves on the carrier tape.

[0029] 5. The present invention can preferably be applicable to the forming of component receiving grooves of various sizes and structural forms, especially the forming of small-sized component receiving grooves, which can avoid the bottom of the component receiving groove from being too thin and ensure the structural strength of the component receiving groove.

During the process of forming the carrier tape, in the stationary stage of the carrier tape, the upper heating cam for heating drives the upper heating module to move downward, and at the same time, the lower heating cam for heating drives the lower heating module to move upward. The heating bumps of the upper heating module and the heating bumps of the lower heating module come into contact to achieve local point heating of the carrier tape. After heating, with the rotation of the upper heating cam and the lower heating cam for heating, the upper heating module and the lower heating module are quickly separated, avoiding the bending deformation of the carrier tape caused by heating and ensuring the flatness of the carrier tape.

[0063] In addition, in order to achieve the smooth discharge of waste after punching, the punching needle II further adopts a hollow punching needle. An air groove 3.4.10 is arranged at the lower end of the forming upper mold fixing plate corresponding to the position of the multiple rows of punching needles II. An air intake passage connected to the air groove is built into one side of the forming upper mold fixing plate, and the outer port of the air intake passage is connected to the external air supply device through an air pipe. A particle blanking slot hole 3.5.10 is arranged on the forming lower mold base corresponding to the position of the multiple rows of punching holes II, and a particle collecting slot 3.5.11 is arranged at the upper end of the forming lower mold fixing plate corresponding to the particle blanking slot hole.

[0064] During the downward movement of the forming upper die assembly, air is instantaneously supplied into the air groove through the air supply device. The fan is turned on before the equipment operates, and the sealed box is always in a negative pressure state. During the instant of forming when the equipment is operating, the waste materials sheared by punching are sucked into the particle collection groove. Under the action of the negative pressure, the waste materials in the particle collection groove enter the sealed box through the air pipe, realizing the collection of waste materials.

[0065] With the rotation of the upper forming cam and the lower forming cam of the above-mentioned groove forming mechanism, the lower end of the upper forming die group and the upper end of the lower forming die group are fitted and pressed against the carrier tape. At the same time, the limit guiding column on the forming unloading plate contacts the forming lower die fixing plate through the corresponding relief hole on the lower forming die base, restricting the downward movement of the unloading plate; Subsequently, the upper forming die fixing plate, the forming positioning plate, the punching needle II, and the upper forming convex tooth continue to move downward. The punching needle II and the upper forming convex tooth extend from the lower end of the unloading plate and cooperate with the punching hole II and the lower forming concave tooth of the lower forming die group respectively to form a part accommodation groove and an indexing positioning hole on the carrier tape.

[0066] The punching execution mechanism is used to punch through holes at the bottom of the formed part accommodation groove. It mainly includes a lower punching die group 4.4, an upper punching die group 4.3, an upper punching die hoisting assembly 4.2, and a cam contact roller for punching.

[0067] The lower punching die base includes a punching base 4.4.2 and a lower punching die 4.4.1. The punching base is fixed on the forming frame. A waste material collection groove 4.4.3 is arranged on the punching base. An air pipe joint is arranged at the waste material collection groove. An air pipe is connected to the air pipe joint, and the other end of the air pipe is connected to a sealed box arranged under the workbench of the frame. The sealed box is connected with a fan, and the tiny pieces of materials punched off are collected into the sealed box through negative pressure. The lower punching die is fixed at the upper end of the punching base. Multiple rows of punching holes III are arranged in the middle of the lower punching die. The multiple rows of punching holes III communicate with the waste material collection groove located below. Guide holes are arranged near both ends of the lower punching die. Further, guide sleeves are installed in the guide holes for the upper punching die group to achieve up and down guiding cooperation.

[0068] The punching upper die assembly includes a punching upper die fixing plate 4.3.1, a punch needle positioning plate 4.3.2, and a punching discharge plate 4.3.3, which are sequentially arranged up and down. Guide shafts 4.3.4 extending downward are fixedly installed at both ends of the punching upper die fixing plate. The two guide shafts pass through the shaft holes at both ends of the punch needle positioning plate and the shaft holes at both ends of the punching discharge plate, and are aligned with the two guide holes on the punching lower die up and down respectively. The punch needle positioning plate is fixedly connected to the punching upper die fixing plate by screws. Multiple rows of punch needles III extending downward are installed on the punch needle positioning plate, and the multiple rows of punch needles III correspond one by one to the multiple rows of punch holes III on the punching lower die. The punch pin positioning plate and the punching stripper plate are loosely connected by screws (i.e., a gap is left between the lower end of the punch pin positioning plate and the upper end of the punching stripper plate). Multiple spring clearance holes are arranged on the punch pin positioning plate. A compression spring III 4.3.5 is installed in each spring clearance hole. The upper and lower ends of the compression spring III are respectively pressed and contacted with the lower end of the punching upper die fixing plate and the upper end of the punching stripper plate. Multiple rows of punch pin through holes are arranged correspondingly at the positions of the punching stripper plate corresponding to the multiple rows of punch pins III.

[0069] The punching upper die group adopts this structural form. During the downward movement of the punching upper die group, the lower end of the punching discharge plate first contacts the upper surface of the carrier tape to clamp and fix the carrier tape. Then, as the punching upper die group continues to descend, the compression spring III is compressed, and multiple rows of punch needles III extend downward through the punch needle holes on the punching discharge plate, and cooperate with the corresponding punch holes III on the punching lower die to form punch holes at the bottom of the part accommodating groove.

[0070] The punching upper die hoisting assembly is used to realize the hoisting of the punching upper die group, and is mainly composed of a punching hanger 4.2.1 and a punching hanger seat 4.2.2 arranged up and down.

A hanging joint is arranged at the lower end of the punching hanger, and the shape of the hanging joint matches the shape of the inverted T-shaped hanging groove. The hanging joint is embedded in the inverted T-shaped hanging groove to realize the upper and lower fixed connection between the punching hanger and the punching hanger seat. A punching guide rail connecting plate is fixed on the back of the punching hanger, and a punching guide block is installed on the back of the punching guide rail connecting plate. The punching guide block cooperates with the punching guide rail fixed on the forming machine frame, and the punching guide rail and the punching guide block constitute a linear guide pair.

[0071] The punching upper cam contact roller is installed on the upper end of the punching hanger, and a tension spring III4.1 is connected between the punching guide connecting plate and the forming machine frame in the up and down direction to ensure that the punching upper cam contact roller always keeps in contact with the lower part of the punching upper cam.

[0072] Furthermore, reserve a position for a punching die at the rear end of the punching mechanism to produce more precise carrier tapes. For example, when the spacing between the part accommodation grooves is 1 mm, the punching pin III cannot be arranged in a single die due to the too small spacing. In this case, the punching pin III can be installed in two groups of punching dies respectively, and the distance of the tape pulling motor can be adjusted to cooperate with the two groups of punching dies to complete punching.

[0073] The tape pulling mechanism includes a tape pulling pinwheel 5.2 and a tape pulling motor 5.1. The output end of the tape pulling motor is connected to the tape pulling pinwheel. A pressure wheel 5.3 is arranged above the tape pulling pinwheel. Since the carrier tape is produced intermittently and continuously, the tape pulling pins on the tape pulling pinwheel cooperate with the index positioning holes punched and formed on the carrier tape, and the carrier tape can be pulled backward in an intermittent motion manner. Four evenly distributed and protruding metal sheets are arranged at the rear end of the tape pulling pinwheel, and a sensor 5.4 is arranged below the pinwheel. When the pinwheel moves, the metal sheets will pass through the sensor to calculate the quantity.

Several gears mesh with each other and are driven by the same power source, the cutter motor.

[0075] The waste material mechanism is used to cut the waste material separated during production to prevent it from affecting the stable production process. The waste material mechanism is arranged below the waste material guiding wheel set of the slitting mechanism, and mainly includes a waste material mechanism base 7.1, a cutting cylinder 7.5, a waste material cutter 7.4, a cutter guiding plate 7.2, and a waste material guiding plate 7.3.

[0077] Figure 19 and Figure 20 is a comparison diagram of the carrier tapes processed by the carrier tape forming machine of the present invention and the existing carrier tape forming machine. From Figure 19It can be seen that the front of the carrier tape processed by the carrier tape forming machine of the present invention is flat, and there are no indentations on the periphery of the component accommodation groove area. However, there are obvious groove lines on the front of the carrier tape processed by the existing carrier tape forming machine in the peripheral area of the component accommodation groove, and the flatness of its surface is poor. From Figure 20 , it can be seen that there are no deformation marks on the back of the carrier tape processed by the carrier tape forming machine of the present invention. Especially in the area outside the component accommodation groove, the uniformity of the component accommodation groove is good. However, there are thermal deformation marks on the back of the carrier tape processed by the existing carrier tape forming machine in the area outside the component accommodation groove, and the uniformity of the component accommodation groove is poor. By comparing the actual processed products, it can be concluded that the carrier tape forming machine of the present invention is superior to the existing carrier tape forming machines in terms of the flatness of the carrier tape forming, the forming quality of the component accommodation groove, and other aspects.
