Description

Technical Field

[0001] The present invention relates to the technical field of carrier tape forming, and particularly relates to a fully automatic carrier tape forming machine and a production process. Background Art

[0002] A carrier tape is a strip-shaped product applied in the field of electronic packaging. It has a specific thickness, and holes (also known as pockets) for holding electronic components and positioning holes for indexing and positioning are equally distributed in its length direction.

[0003] Generally, after the carrier tape is initially processed by a forming mechanism and a punching mechanism, it is necessary to cool down the formed carrier tape. In the prior art, a cooling fan is usually arranged below the conveyor of the carrier tape to quickly cool down the carrier tape. However, in actual use, when the temperature difference between the external air and the carrier tape is too large, the extremely rapid cooling will cause the carrier tape to shrink too much (such as PET is prone to crystallization and shrinkage), which will make the size fluctuation range of the carrier tape larger and affect the compatibility between the subsequent carrier tape and the mounter. Summary of the Invention

[0004] Technical Problems to be Solved

[0005] In view of the above-mentioned drawbacks of the prior art, the present invention provides a fully automatic carrier tape forming machine and a production process, which can effectively solve the problem that in the prior art, a cooling fan is usually arranged below the conveyor of the carrier tape to quickly cool down the carrier tape. However, in actual use, when the temperature difference between the external air and the carrier tape is too large, the extremely rapid cooling will cause the carrier tape to shrink too much, which will make the size fluctuation range of the carrier tape larger and affect the compatibility between the subsequent carrier tape and the mounter.

[0006] Technical Solutions

[0007] To achieve the above object, the present invention is realized through the following technical solutions:

[0008] The present invention provides a fully automatic carrier tape forming machine and a production process, including a frame. A heating mechanism, a forming mechanism, a punching mechanism, and a feeding mechanism are sequentially arranged on the frame. It further includes:

[0009] A cooling box, fixedly installed on the frame and located between the punching mechanism and the feeding mechanism. The cooling box is used for uniformly cooling and shaping the formed carrier tape body. Through holes for the carrier tape body to enter and exit are arranged at both the front and rear ends of the cooling box.

[0010] The upper end of the cooling box is provided with a heat dissipation opening in the shape of an isosceles triangle. A heat dissipation box is fixedly installed inside the cooling box. A jet groove is arranged above the heat dissipation box. The upper end of the heat dissipation box extends to directly below the carrier tape body. A storage cylinder is arranged below the heat dissipation box, and the storage cylinder is used to generate heat dissipation gas and continuously supply the heat dissipation gas to the heat dissipation box.

[0011] Further, a partition is arranged in the middle of the cooling box. The partition divides the interior of the cooling box into a first heat dissipation space and a second heat dissipation space. Heat dissipation boxes and storage cylinders for supplying heat dissipation gas to the interior of the heat dissipation boxes are arranged in both the first heat dissipation space and the second heat dissipation space.

[0012] Further, a linear guide rail is fixedly installed on the upper end surface of the frame. A linear motor is drivingly installed above the linear guide rail. The feeding mechanism is fixedly installed above the linear motor. When the feeding mechanism is fixedly installed on the carrier tape body, the linear motor drives the feeding mechanism and the carrier tape body to move synchronously.

[0013] Further, a piston rod extends from one end of the storage cylinder. The piston rod is used to squeeze the gas inside the storage cylinder into the heat dissipation box. An elastic member is sleeved outside the piston rod. The elastic member is used to drive the piston rod to extend out of the storage cylinder. A linkage plate for driving the piston rod to squeeze the gas inside the storage cylinder is arranged on the side surface of the cooling box. A limiting plate for driving the linkage plate to move horizontally is arranged on one side of the linear motor.

[0014] Further, a long strip-shaped guiding through hole is arranged on the side surface of the cooling box. One side of the linkage plate passes through the guiding through hole and is slidably connected to the inner wall of the guiding through hole. A pressing plate is arranged on the linkage plate. When the linear motor moves towards the linkage plate, the limiting plate abuts against the pressing plate to compress the gas inside the storage cylinder by the piston rod.

[0015] Further, a delivery pipe and an intake pipe are respectively arranged on the storage cylinder. The other end of the delivery pipe is communicated with the interior of the heat dissipation box. A one-way valve for restricting the one-way inflow of air into the heat dissipation box is arranged on the delivery pipe. The other end of the intake pipe extends out of the cooling box and is communicated with the external air. Another group of one-way valves for restricting the one-way entry of air into the storage cylinder is arranged on the intake pipe.

[0016] Further, multiple groups of jet nozzles are symmetrically arranged on both sides of the heat dissipation box. The multiple groups of jet nozzles are communicated with the interior of the heat dissipation box, and the multiple groups of jet nozzles are used to spray heat dissipation gas between the storage units of the carrier tape body.

[0017] Further, the jet nozzle includes a fixing part for communicating with the inside of the heat dissipation box. On the side of the fixing part away from the heat dissipation box, there is a bending part. An exhaust through hole is arranged on the inner side of the bending part. On the side of the bending part away from the heat dissipation box, there is a contact part. The fixing part, the bending part and the contact part are of an integrally formed structure and are hollow inside. The bending part has elasticity.

[0018] A production process of a carrier tape, and the production process specifically includes the following steps:

[0019] Step 1: First, install the rolled carrier tape sheet on the feeding reel at the front end of the rack, unfold and feed it into the production line, and ensure uniform tension to avoid wrinkles or breaks;

[0020] Step 2: After that, the softened sheet is adsorbed onto the surface of the mold (such as a roller mold or a fixed mold) by vacuum, and carrier tape holes or embossings are formed by air pressure. At the same time, a pneumatic clamping cylinder or an adjustable guide plate is used to reduce the displacement of the carrier tape during the forming process and improve the positioning accuracy;

[0021] Step 3: Then, a punching die punches positioning holes or functional holes in the carrier tape, and some equipment integrates a punching detection device to ensure the punching accuracy on the carrier tape body;

[0022] Step 4: Finally, the formed carrier tape is quickly and evenly cooled at the cooling box to prevent deformation or surface cracks, and the processed and formed carrier tape body is collected by the winding mechanism at the tail of the rack.

[0023] Beneficial effects

[0024] The technical solution provided by the present invention has the following beneficial effects compared with the known public technologies:

[0025] 1. In the present invention, by arranging a cooling box between the punching mechanism and the feeding mechanism and arranging a heat dissipation box inside the cooling box, after the carrier tape body enters the cooling box from the punching mechanism, the jet slots above the heat dissipation box evenly spray heat dissipation gas towards the middle of the carrier tape body, and the heat dissipation gas diffuses from the middle of the carrier tape body to both sides of the carrier tape body, which can quickly and evenly take away the heat on the carrier tape body, and can avoid excessive shrinkage of the carrier tape body during the rapid cooling process, and avoid excessive dimensional error of the carrier tape body.

[0026] 2. In the present invention, by using a partition to divide the inside of the cooling box into a first heat dissipation space and a second heat dissipation space, the heat dissipation and cooling of the carrier tape body can be divided into two steps. The first heat dissipation space is responsible for slowly reducing the temperature of the carrier tape body from a high temperature to reduce the temperature difference between the carrier tape body and the outdoor temperature, and the second heat dissipation space is used to quickly reduce the temperature of the carrier tape body to make the temperature of the carrier tape body close to the outdoor temperature.

[0027] 3. In the present invention, a piston rod is provided at one end of the storage cylinder, and a linkage plate is slidably arranged inside the cooling box. During the reciprocating movement of the linear motor, it can conveniently drive the piston rod to compress the air inside the storage cylinder and enter the heat dissipation box. By using the reciprocating movement of the linear motor, the carrier tape body located inside the cooling box can be evenly cooled, and the reciprocating movement stroke of the linear motor can be fully utilized.

[0028] 4. In the present invention, the middle part of the air jet nozzle is provided with a bent part which is bent and has elasticity. When the contact parts between the outer walls of the storage units on both sides of the middle part of the carrier tape body come into contact with the air jet nozzle, the contact parts can drive the extrusion of the bent part, blocking the exhaust through holes at the bent part, reducing the exhaust volume at the exhaust through holes, enabling more heat dissipation gas to flow through the outer walls of the storage units on both sides of the middle part of the carrier tape body, and more precisely cooling each position of the carrier tape body.

[0045] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] The present invention will be further described below with reference to the embodiments.

[0047] Embodiment: A fully automatic carrier tape forming machine, as Figure 1 - Figure 4 shown, includes a frame 1, on which a heating mechanism 2, a forming mechanism 3, a punching mechanism 4 and a feeding mechanism 6 are arranged in sequence. It further includes:

[0048] A cooling box 5, fixedly installed on the frame 1 and located between the punching mechanism 4 and the feeding mechanism 6. The cooling box 5 is used for uniformly cooling and shaping the formed carrier tape body 7. Through holes for the carrier tape body 7 to enter and exit are provided at both the front and rear ends of the cooling box 5;

[0049] The upper end of the cooling box 5 is provided with a heat dissipation port 501 in the shape of an isosceles triangle. Inside the cooling box 5, a heat dissipation box 55 is fixedly installed. Above the heat dissipation box 55, there is a jet groove 5501. The upper end of the heat dissipation box 55 extends to directly below the carrier tape body 7. Below the heat dissipation box 55, there is a storage cylinder 51, which is used to generate heat dissipation gas and continuously supply the heat dissipation gas to the heat dissipation box 55.

[0050] In the present invention, by arranging the cooling box 5 between the punching mechanism 4 and the feeding mechanism 6, and arranging the heat dissipation box 55 inside the cooling box 5, after the carrier tape body 7 enters the inside of the cooling box 5 from the punching mechanism 4, the jet groove 5501 above the heat dissipation box 55 evenly sprays the heat dissipation gas towards the middle of the carrier tape body 7. The heat dissipation gas diffuses from the middle of the carrier tape body 7 to both sides of the carrier tape body 7, and can quickly and evenly take away the heat on the carrier tape body 7, avoiding excessive shrinkage of the carrier tape body 7 during the rapid cooling process and preventing the dimensional error of the carrier tape body 7 from being too large.

[0051] It should be noted that since the storage cylinder 51 is located inside the cooling box 5, during the air supply stage, the air entering the inside of the storage cylinder 51 can be preliminarily heated. By controlling the size of the heat dissipation port 501, the heating degree of the storage cylinder 51 can be controlled, which is more suitable for the processing scenario where the temperature difference between the external environment temperature and the carrier tape processing temperature is too large. In addition, the heating mechanism 2, the forming mechanism 3, the punching mechanism 4, and the feeding mechanism 6 are all conventional structural designs in the prior art and are conventional technical means in the prior art, which will not be elaborated in this application.

[0052] Furthermore, as Figure 6 shown, a partition 54 is arranged in the middle of the cooling box 5. The partition 54 divides the inside of the cooling box 5 into a first heat dissipation space and a second heat dissipation space. Inside both the first heat dissipation space and the second heat dissipation space, there are heat dissipation boxes 55 and storage cylinders 51 for supplying heat dissipation gas to the inside of the heat dissipation boxes 55.

[0053] Among them, by using the partition 54 to divide the inside of the cooling box 5 into a first heat dissipation space and a second heat dissipation space, the heat dissipation and temperature reduction of the carrier tape body 7 can be divided into two steps. The first heat dissipation space is responsible for slowly reducing the temperature of the carrier tape body 7 from a high temperature and reducing the temperature difference between the carrier tape body 7 and the outdoor temperature. The second heat dissipation space is used to quickly reduce the temperature of the carrier tape body 7 so that the temperature of the carrier tape body 7 approaches the outdoor temperature (achieved by increasing the heat dissipation port 501 above the corresponding second heat dissipation space);

[0054] Furthermore, as Figure 4As shown, a linear guide rail 62 is fixedly installed on the upper end surface of the frame 1. Above the linear guide rail 62, a linear motor 61 is drivingly installed. The feeding mechanism 6 is fixedly installed above the linear motor 61. When the feeding mechanism 6 is fixedly installed on the carrier tape body 7, the linear motor 61 drives the feeding mechanism 6 and the carrier tape body 7 to move synchronously.

[0055] Among them, by slidably installing the linear motor 61 on the frame 1, during use, the linear motor 61 can reciprocally drive the feeding mechanism 6 to convey the carrier tape body 7, which can conveniently control the moving speed of the carrier tape body 7. In addition, the reciprocating stroke of the linear motor 61 is equal to the lengths of the first heat dissipation space and the second heat dissipation space. During one stroke of the linear motor 61, a certain section of the carrier tape body 7 staying inside the first heat dissipation space is brought into the second heat dissipation space, so that each section of the carrier tape body 7 will stay inside the first heat dissipation space and the second heat dissipation space.

[0056] Furthermore, as Figure 5 and Figure 6 shown, a piston rod 511 extends from one end of the storage cylinder 51. The piston rod 511 is used to squeeze the gas inside the storage cylinder 51 into the heat dissipation box 55. An elastic member 52 is sleeved outside the piston rod 511. The elastic member 52 is used to drive the piston rod 511 to extend out of the storage cylinder 51. A linkage plate 53 for driving the piston rod 511 to squeeze the gas inside the storage cylinder 51 is arranged on the side surface of the cooling box 5. A limiting plate 611 for driving the linkage plate 53 to move horizontally is arranged on one side of the linear motor 61.

[0057] Among them, by arranging the piston rod 511 at one end of the storage cylinder 51 and slidably arranging the linkage plate 53 inside the cooling box 5, during the reciprocating movement stroke of the linear motor 61, it can conveniently drive the piston rod 511 to compress the air inside the storage cylinder 51 into the heat dissipation box 55, and use the reciprocating movement of the linear motor 61 to evenly dissipate heat from the carrier tape body 7 located inside the cooling box 5. The reciprocating movement stroke of the linear motor 61 can be fully utilized (when the linear motor 61 moves away from the cooling box 5, it moves the carrier tape body 7, and when the linear motor 61 approaches the cooling box 5, it does not carry a load and can easily drive the linkage plate 53 to compress the air inside the storage cylinder 51). In addition, the storage cylinder 51 is a common piston cylinder in the prior art and will not be elaborated in this application.

[0058] Furthermore, as Figure 4 and 6As shown, a long strip-shaped guiding through hole 502 is provided on the side of the cooling box 5. One side of the linkage plate 53 passes through the guiding through hole 502 and is slidably connected to the inner wall of the guiding through hole 502. A pressing plate 531 is provided on the linkage plate 53. During the movement of the linear motor 61 towards the linkage plate 53, the limiting plate 611 abuts against the pressing plate 531 to compress the gas inside the storage cylinder 51 by the piston rod 511.

[0059] Among them, by providing the guiding through hole 502 on the cooling box 5, the linkage plate 53 passes through the guiding through hole 502 and is slidably connected to the inner wall of the guiding through hole 502. During the sliding process of the linkage plate 53, the guiding through hole 502 can guide and support the linkage plate 53, enabling the linkage plate 53 to slide linearly and stably.

[0060] Furthermore, as Figure 6 and Figure 7 shown, a delivery pipe 512 and an intake pipe 513 are respectively provided on the storage cylinder 51. The other end of the delivery pipe 512 is communicated with the inside of the heat dissipation box 55. A one-way valve for restricting the one-way inflow of air into the inside of the heat dissipation box 55 is provided on the delivery pipe 512. The other end of the intake pipe 513 extends out of the cooling box 5 and is communicated with the external air. Another set of one-way valves for restricting the one-way entry of air into the inside of the storage cylinder 51 is provided on the intake pipe 513.

[0061] Among them, by respectively providing the delivery pipe 512 and the intake pipe 513 on the storage cylinder 51, the gas can be smoothly guided to enter the inside of the storage cylinder 51 from the intake pipe 513. Then, under the action of the piston rod 511, these gases are further squeezed and conveyed along the delivery pipe 512 into the inside of the heat dissipation box 55, sucking in the heat dissipation air from the outside, which can quickly cool down the carrier tape body 7.

[0062] Furthermore, as Figure 9 and Figure 10 shown, multiple groups of jet nozzles 56 are symmetrically provided on both sides of the heat dissipation box 55. The multiple groups of jet nozzles 56 are communicated with the inside of the heat dissipation box 55. The multiple groups of jet nozzles 56 are used to spray heat dissipation gas between the storage units of the carrier tape body 7.

[0063] Among them, by providing the jet nozzles 56 on both sides of the heat dissipation box 55, it is convenient to accurately cool the outside of the storage units on the carrier tape body 7, which can further improve the uniformity of the temperature reduction on the outside of the carrier tape body 7 and avoid excessive local contraction of the carrier tape body 7 caused by local temperature reduction.

[0064] Further, the jet nozzle 56 includes a fixing portion 561 for communicating with the inside of the heat dissipation box 55. On the side of the fixing portion 561 away from the heat dissipation box 55, there is a bending portion 562. On the inner side of the bending portion 562, there is an exhaust through hole 5601. On the side of the bending portion 562 away from the heat dissipation box 55, there is a contact portion 563. The fixing portion 561, the bending portion 562, and the contact portion 563 are integrally formed structures and are hollow inside. The bending portion 562 has elasticity.

[0065] Among them, by setting the middle part of the jet nozzle 56 as the bending portion 562 with a bending shape and making the bending portion 562 have elasticity, when the outer walls of the storage units on both sides of the middle part of the carrier tape body 7 come into contact with the contact portion 563 of the jet nozzle 56, it can drive the contact portion 563 to squeeze the bending portion 562, so that the exhaust through hole 5601 at the bending portion 562 is blocked, the exhaust volume at the exhaust through hole 5601 can be reduced, and more heat dissipation gas can flow through the outer walls of the storage units on both sides of the middle part of the carrier tape body 7 (the area that needs heat dissipation at the position not in contact with the contact portion 563 is larger and more heat dissipation gas is required), and the temperature of each position of the carrier tape body 7 can be reduced more precisely.

[0066] A production process of a carrier tape, and the production process specifically includes the following steps:

[0067] Step 1: First, install the rolled carrier tape sheet on the feeding reel at the front end of the frame 1, unfold and feed it into the production line, and ensure uniform tension to avoid wrinkles or breaks;

[0068] Step 2: Then, the softened sheet is adsorbed onto the surface of the mold (such as a roller mold or a fixed mold) by vacuum, and carrier tape holes or embossings are formed by air pressure. At the same time, a pneumatic clamping cylinder or an adjustable guide plate is used to reduce the displacement of the carrier tape during the forming process and improve the positioning accuracy;

[0069] Step 3: Then, a punching die punches positioning holes or functional holes on the carrier tape, and some equipment integrates a punching detection device to ensure the punching accuracy on the carrier tape body 7;

[0070] Step 4: Finally, the formed carrier tape is quickly and evenly cooled through the cooling box 5 to prevent deformation or surface cracks, and the processed and formed carrier tape body 7 is collected by the winding mechanism at the tail of the frame 1.

[0071] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
