Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing, and particularly relates to a tape hot pressing device for flexible printed circuit boards. Background Art

[0002] A flexible printed circuit board is a circuit board made of a flexible substrate, having good flexibility and bendability. It is widely used in electronic products such as mobile phones, tablet computers, wearable devices, etc. One of the advantages of a flexible printed circuit board is its flexibility, which meets the conditions for shaping it. To shape a product, conditions for fixing the shape after shaping are required. Applying tape is one of the commonly used methods for fixing the shape. Usually, multiple tapes need to be attached to the flexible printed circuit board. To activate the stickiness of the tape by heating the tape (when hot pressing the tape, the pressing head descends to the PI film to heat the tape to activate the stickiness of the tape, where the PI film refers to the stable film in this application). After the tape is attached, in order to ensure its stability on the flexible printed circuit board, it needs to be pressed at a certain pressure and a certain temperature.

[0003] The current pressing methods have at least the following problems:

[0004] 1. Most of the existing pressing methods are single-piece pressing, which will undoubtedly waste a lot of time and result in the inability to guarantee production efficiency.

[0005] 2. The single-piece pressing method can often only perform hot pressing operations on a single type of tape, that is, after the hot pressing operation of the previous tape is completed, the hot pressing of the next tape can be carried out. This makes the overall hot pressing efficiency very low.

[0006] Therefore, how to solve the deficiencies of the above-mentioned existing technologies has become the research topic of the present utility model. Summary of the Utility Model

[0007] The present utility model provides a tape hot pressing device for flexible printed circuit boards, aiming to solve the technical problems raised in the above background art.

[0008] To achieve the above object, the technical solution adopted by the present utility model is: a tape hot pressing device for flexible printed circuit boards, the tape hot pressing device includes a carrier, a hot pressing head module, a stable film module, a streamline, and a lifting mechanism;

[0009] The streamline is arranged on the upper surface of the workbench. There is a pressing station on the streamline. The carrier is transferred by the streamline to the pressing station. The carrier is provided with a plurality of carrying positions for carrying the same type or different types of products and a tape attaching position for attaching tapes to the surface of each product;

[0010] The stable film module includes a fixed bracket and a film limiting bracket. The fixed bracket is positioned and installed on the upper surface of the working cabinet. The film limiting bracket is arranged on the fixed bracket. The film limiting bracket is provided with a plurality of stable films. Each stable film is configured to correspond to each carrying position respectively. The stable film has a horizontally arranged horizontal section. When the carrier is positioned at the pressing station, the horizontal section is located directly above the carrying position.

[0011] The lifting mechanism is positioned and connected to the upper surface of the working cabinet and is arranged at the pressing station. The movable end of the lifting mechanism is used to push the carrier to rise until each product fits against the horizontal section of each stable film.

[0012] The hot pressing head module includes a plurality of up-and-down movement modules. Each up-and-down movement module is located above the pressing station. The lower end of each up-and-down movement module serves as a movable end, and the movable end of each up-and-down movement module has a pressing head. When the carrier is positioned at the pressing station, each pressing head is configured to correspond to each gluing position respectively. The up-and-down movement module is used to push the pressing head to apply a set range of pressure and temperature to the surface of the horizontal section that is in contact with the tape.

[0013] In the above technical solution, with the upper surface of the working cabinet as a reference, the streamline is on the upper surface of the working cabinet, the carrier is at the pressing station on the streamline. At this time, the stable film module is arranged above the pressing station, the hot pressing head module is above the stable film module, and the lifting mechanism is below the carrier, and they are arranged in sequence from bottom to top in this way.

[0014] In the above technical solution, when the product fits against the horizontal section of the stable film, it means that the tape attached to each product will also fit against this horizontal section.

[0015] A further technical solution is that the pressing head includes a mounting block connected to the movable end of the up-and-down movement module and a pressing head facing the tape. The pressing head is used to heat the surface of the horizontal section in contact with the tape. The mounting block is provided with a detachably connected weight block. The pressing head passes through the mounting block, and the passing end of the pressing head is connected to the weight block.

[0016] When the pressing head cooperates with the weight block to apply pressure to the surface of the horizontal section in contact with the tape, different weights of weight blocks are replaced to change the pressure applied to the corresponding tape.

[0017] With the above design, the pressing head can apply different pressures and temperatures (applying temperature is for heating) to the tapes attached to different types of products. And this way can make the overall volume of the pressing head small. The hot pressing temperature of the pressing head can be controlled by an industrial control computer to control the heating rod to achieve the hot pressing temperature control of different tapes.

[0018] Further technical solution: The hot pressing head module further includes two gantry frames and a cross beam frame;

[0019] Each gantry frame is positioned and connected to the upper surface of the working cabinet through supporting parts arranged at both ends. The cross beam frame is connected to the same side of the two gantry frames and is located above the pressing station. All the up-and-down movement modules are arranged on the cross beam frame and are located between the two gantry frames.

[0020] With the above design, the position of the up-and-down movement module is restricted, and at the same time, preliminary positioning operation can be realized to prevent the up-and-down movement module from running out of the edge of the pressing station.

[0021] It should be noted that: The up-and-down movement module can select mechanisms such as cylinders, lead screw and sliding sleeve mechanisms, or electric push rods that can drive the pressing head to move up and down.

[0022] Further technical solution: The fixed bracket includes two limiting frames located between the two gantry frames and arranged parallel to each gantry frame. The limiting frames are positioned and installed on the upper surface of the working cabinet, and an installation interval is formed between the two limiting frames;

[0023] The film limiting frame is arranged in this installation interval;

[0024] The stabilizing film is arranged parallel to the two limiting frames.

[0025] With the above design, the position of the film limiting frame is further limited, so that the multiple stabilizing films arranged on the film limiting frame will not deviate from the installation interval.

[0026] Further technical solution: The film limiting frame includes a take-up rod and a pay-off rod. The take-up rod and the pay-off rod are respectively located at both ends of this installation interval; A plurality of take-up wheels are arranged on the take-up rod, and a plurality of pay-off wheels are arranged on the pay-off rod. Each take-up wheel and each pay-off wheel are correspondingly arranged and combined to form a plurality of take-up and pay-off structures;

[0027] Each take-up and pay-off structure is correspondingly arranged with each stabilizing film for winding and unwinding the stabilizing film.

[0028] With the above design, the stabilizing film can be freely wound and unwound, so that the product to be hot-pressed and the tape are always attached to the newly released stabilizing film.

[0029] Further technical solution: The film limiting frame further includes a plurality of limiting rods arranged in a linear array between the take-up rod and the pay-off rod. The limiting rods are arranged parallel to the take-up rod. Anti-deviation wheel groups are arranged on all the limiting rods along the length direction of the horizontal section. The anti-deviation wheel groups are used to limit the inclination of the position of the horizontal section.

[0030] Since the stabilizing film will contract when heated, with the above design, the position of the stabilizing film is restricted, and even if it contracts, it will not deviate from the original linear motion direction.

[0031] In a further technical solution, the anti-deviation wheel set is a pair of coaxial wheels arranged on the limiting rod.

[0032] With the above design, by clamping the two sides of the stabilizing film with a pair of coaxial wheels, the position limitation of the stabilizing film can be achieved.

[0033] In a further technical solution, the movable end of the lifting mechanism is configured to act on the middle area or both sides of the lower surface of the carrier.

[0034] That is, the installation position of the lifting mechanism is not fixed. When encountering a wider carrier, it is easy for the carrier to shake when being pushed up from the bottom of the carrier. Therefore, with the above design, the movable end of the lifting mechanism can be set on both sides or the middle area of the lower surface of the carrier according to the size of the carrier width.

[0035] In a further technical solution, the flow lines are two linear guide rails arranged on the upper surface of the work cabinet.

[0036] With the above design, the phenomenon that the position of the carrier does not deviate during the transmission by the linear guide rails can be avoided.

[0037] In a further technical solution, an adjustment guide rail connected to the upper surface of the work cabinet is provided at the bottom of the flow lines for adjusting the width between the linear guide rails.

[0038] With the above design, the width between the two linear guide rails can be adjusted, which is convenient for corresponding designs for carriers of different widths.

[0044] The working principle and advantages of this utility model are as follows:

[0045] In this utility model, through multiple bearing positions on the carrier and the cooperation with multiple up-and-down movement modules and multiple stabilizing films, the following can be achieved: 1. The coordinated cooperation of multiple bearing positions can simultaneously carry multiple products and perform pressing operations, saving working hours compared with single-piece pressing in the prior art; 2. The corresponding setting of multiple bearing positions with multiple up-and-down movement modules can press products of the same type or different types, and has a high hot pressing efficiency compared with single-type pressing in the prior art.

[0046] Specifically, products of the same type or different types are selected according to the number of bearing positions. Then, the carrier loaded with products is placed on the production line. Subsequently, the carrier is transferred by the production line to the pressing station. After that, the carrier stops moving. Then, the movable end of the lifting mechanism will push the carrier to rise until each tape attached to the product fits with the horizontal section of each stabilizing film. Then, each up-and-down movement module will push the pressing head thereon to apply a set range of pressure and temperature to the surface of the horizontal section that fits with the tape.

Specific embodiments

[0060] The present utility model will be further described below in conjunction with the drawings and embodiments:

[0061] Embodiment: The present case will be clearly described below with diagrams and detailed descriptions. After any person skilled in the art understands the embodiments of the present case, the techniques taught by the present case can be changed and modified without departing from the spirit and scope of the present case.

[0062] The terms used in this article are only for describing specific embodiments and are not intended to limit the present case. Singular forms such as "a", "this", "this", "the present", and "the" also include plural forms as used herein.

[0063] Refer to the attached Figures 1 - 12 As shown, a tape hot pressing device for flexible circuit boards, the tape hot pressing device includes a carrier 2, a hot pressing head module 3, a stable film module 4, a streamline 5, and a jacking mechanism 6;

[0064] The streamline 5 is arranged on the upper surface of the working cabinet 1. There is a pressing station on the streamline 5. The carrier 2 is transferred by the streamline 5 to the pressing station. Multiple loading positions 29 for loading products of the same type or different types and a tape pasting position 30 for pasting tapes on the surface of each product are provided on the carrier 2.

[0065] The stable film module 4 includes a fixed bracket 7 and a film limiting frame 8. The fixed bracket 7 is positioned and installed on the upper surface of the working cabinet 1. The film limiting frame 8 is arranged on the fixed bracket 7. Multiple stable films 18 are provided on the film limiting frame 8. Each stable film 18 is configured to correspond to each loading position 29 respectively. A horizontal section 9 is horizontally arranged on the stable film 18. When the carrier 2 is positioned at the pressing station, the horizontal section 9 is located directly above the loading position 29.

[0066] The jacking mechanism 6 is positioned and connected to the upper surface of the working cabinet 1 and is arranged at the pressing station. The movable end of the jacking mechanism 6 is used to push the carrier 2 to rise until each product fits against the horizontal section 9 of each stable film 18.

[0067] The hot pressing head module 3 includes a plurality of up-and-down movement modules 11. Each up-and-down movement module 11 is located above the pressing station. The lower end of each up-and-down movement module 11 serves as the movable end, and a pressing head 12 is provided at the movable end of each up-and-down movement module 11. When the carrier 2 is positioned at the pressing station, each pressing head 12 is configured to correspond to each tape pasting position 30 respectively. The up-and-down movement module 11 is used to push the pressing head 12 to apply a set range of pressure and temperature to the surface of the horizontal section 9 in contact with the tape.

[0068] In the present utility model, through the multiple loading positions 29 on the carrier 2 and the cooperation with the multiple up-and-down movement modules 11 and the multiple stable films 18, the following can be achieved: 1. The coordinated cooperation of the multiple loading positions 29 can simultaneously load multiple products and perform pressing operations, saving working hours compared with single-piece pressing in the prior art; 2. The corresponding arrangement of the multiple loading positions 29 and the multiple up-and-down movement modules 11 can press products of the same type or different types, and the hot pressing efficiency is high compared with single-type pressing in the prior art.

[0069] Specifically, products of the same type or different types are selected according to the number of the loading positions 29. Then, the carrier 2 loaded with products is placed on the streamline 5. Subsequently, the carrier 2 is transferred by the streamline 5 to the pressing station. After that, the carrier 2 stops moving. Then, the movable end of the jacking mechanism 6 will push the carrier 2 to rise until each product fits against the horizontal section 9 of each stable film 18. Then, each up-and-down movement module 11 pushes the pressing head 12 thereon to apply a set range of pressure and temperature to the surface of the horizontal section 9 in contact with the tape.

[0070] It should be noted that: as pointed out in the background art, the indenter descends onto the PI film to heat the tape to activate the tape's adhesiveness. From this, it can be seen that the PI film (i.e., the stable film 18 in the present application) only serves to separate the indenter head 12 from the tape attached to the product surface. Figure 12 The position of the horizontal section 9 is indicated by the dashed line in the figure.

[0071] In some specific embodiments, the indenter head 12 includes a mounting block 13 connected to the movable end of the up-and-down movement module 11 and a pressing head 14 disposed opposite to the tape. The pressing head 14 is used to heat the surface of the horizontal section 9 that is in contact with the tape. A counterweight block 15 is detachably connected to the mounting block 13. The pressing head 14 is passed through the mounting block 13, and the passing end of the pressing head 14 is connected to the counterweight block 15;

[0072] When the pressing head 14, in cooperation with the counterweight block 15, applies pressure to the surface of the horizontal section 9 that is in contact with the tape, the pressure applied to the corresponding tape is changed by replacing the counterweight block 15 with different weights.

[0073] Refer to Figures 1 - 12 As shown in the figure, the following example is given with two carrying positions 29, two up-and-down movement modules 11, and two stable films 18:

[0074] Since the indenter head 12 needs to apply both pressure and temperature to the tape, for this purpose, the following embodiments are provided:

[0075] It should be noted that: the hot pressing temperature of the pressing head 14 can be controlled by an industrial control computer to control the heating rod to achieve the hot pressing temperature control of different tapes. The lifting mechanism 6 can be selected from a cylinder, an electric push rod, or a lead screw and nut mechanism. Both of the two up-and-down movement modules 11 can be selected as cylinders.

[0076] Specifically, when the movable end of the lifting mechanism 6 pushes the carrier 2 up to make each product fit with the horizontal section 9 of each stable film 18 (the tape on the product also fits with the horizontal section 9), the movable ends of the two up-and-down movement modules 11 will simultaneously descend and respectively push the corresponding mounting blocks 13 down. Then, the two mounting blocks 13 will drive the corresponding pressing heads 14 to respectively press on the surfaces of the two horizontal sections 9 that are in contact with the tape. At this time, each pressing head 14 itself will apply a certain temperature to the surface of the horizontal section 9, and at the same time, each pressing head 14 will also receive the pressure from the corresponding counterweight block 15, so that the surface of the horizontal section 9 will also be subjected to pressure, thus achieving the purpose of hot pressing the product (specifically, completing the hot pressing of the tape).

[0077] Due to the different types of products, the pressure applied to the corresponding tape can be changed by replacing the counterweight block 15 with different weights.

[0078] In order to ensure that the heights of the two up-and-down movement modules 11 are sufficient, the following embodiments of installation and fixation are provided:

[0079] The hot pressing head module 3 further includes two gantry frames 10 and a cross beam frame 16;

[0080] Each gantry frame 10 is positioned and connected to the upper surface of the working cabinet 1 through the supporting parts 17 provided at both ends. The cross beam frame 16 is connected to the same side of the two gantry frames 10 and is located above the pressing station. All the up-and-down movement modules 11 are arranged on the cross beam frame 16 and are located between the two gantry frames 10.

[0081] First, place the two gantry frames 10 on the upper surface of the working cabinet 1, and make the two gantry frames 10 and the streamline 5 present a vertical and horizontal intersection form in the top view projection (two horizontal and two vertical lines form a structure similar to a well shape).

[0082] Then, through mechanisms such as screws, positionally connect the supporting parts 17 to the upper surface of the working cabinet 1. Subsequently, arrange the cross beam frame 16 on the same side of the two gantry frames 10 and above the pressing station. Finally, arrange the two up-and-down movement modules 11 on the cross beam frame 16 and between the two gantry frames 10.

[0083] An embodiment for the stable film module 4 is provided:

[0084] The fixing bracket 7 includes two limiting frames 19 located between the two gantry frames 10 and arranged in parallel with each gantry frame 10. The limiting frames 19 are positionally installed on the upper surface of the working cabinet 1, and an installation interval is formed between the two limiting frames 19;

[0085] The film limiting frame 8 is arranged within this installation interval;

[0086] The stable film 18 is arranged in parallel with the two limiting frames 19.

[0087] When fixing the fixing bracket 7, first place the two limiting frames 19 between the two gantry frames 10 and make the two limiting frames 19 arranged in parallel with each gantry frame 10.

[0088] After that, through structures such as screws or pins, fix the limiting frames 19 to the working cabinet 1 or the gantry frames 10. In this application, it can be selected to be fixed to the working cabinet 1 to make its stability high.

[0089] When the limiting frames 19 are fixed, an installation interval is formed between the two limiting frames 19; the film limiting frame 8 is arranged within this installation interval; the stable film 18 is arranged in parallel with the two limiting frames 19, so that the horizontal section 9 in the stable film 18 is longer, and the phenomenon that the two ends of the horizontal section 9 are greatly pulled when heated and shrunk will not occur.

[0090] An embodiment for stably fixing the film 18 is provided for the film limiting frame 8. The film limiting frame 8 includes a take-up rod 20 and a pay-off rod 21, and the take-up rod 20 and the pay-off rod 21 are respectively located at both ends of this installation interval; a plurality of take-up wheels 28 are provided on the take-up rod 20, and a plurality of pay-off wheels 22 are provided on the pay-off rod 21. Each take-up wheel 28 and each pay-off wheel 22 are correspondingly arranged and combined to form a plurality of take-up and pay-off structures;

[0091] Each take-up and pay-off structure is correspondingly arranged with each stable film 18 respectively for winding and unwinding the stable film 18.

[0092] Specifically, the take-up rod 20 and the pay-off rod 21 are positioned and installed at both ends of the installation interval, and the two ends of the stable film 18 are respectively wound around the take-up rod 20 and the pay-off rod 21, and the horizontal section 9 is formed between the take-up rod 20 and the pay-off rod 21. Since two stable films 18 are provided, two take-up rods 20 and two pay-off rods 21 are respectively provided, and the take-up rod 20 and the pay-off rod 21 move together to ensure the stability of the stable film 18 during winding and unwinding.

[0093] In some specific embodiments, the film limiting frame 8 further includes a plurality of limiting rods 23 arranged in a linear array between the take-up rod 20 and the pay-off rod 21. The limiting rods 23 are arranged parallel to the take-up rod 20, and anti-deviation wheel groups 24 are arranged on all the limiting rods 23 along the length direction of the horizontal section 9. The anti-deviation wheel groups 24 are used to limit the inclination of the position of the horizontal section 9.

[0094] In some specific embodiments, the anti-deviation wheel group 24 is a pair of coaxial wheels 25 arranged on the limiting rod 23.

[0095] Due to the shrinkage and other conditions of the horizontal section 9 after heating and the influence of the pressing and disengaging actions of the pressing head 12, the horizontal section 9 is prone to deviation. Therefore, when the horizontal section 9 is performing winding and unwinding operations, the anti-deviation wheel group 24 will play a limiting role to limit the inclination of the position of the horizontal section 9.

[0096] And the anti-deviation wheel group 24 is a pair of coaxial wheels 25 arranged on the limiting rod 23, that is, the position limitation is realized by two coaxial wheels 25 respectively located on both sides of the horizontal section 9.

[0097] In some specific embodiments, the movable end of the lifting mechanism 6 is configured to act on the middle area or both sides of the lower surface of the carrier 2.

[0098] The lifting mechanism 6 can be arranged in the middle area of the lower surface of the carrier 2. For details, reference can be made to Figure 2 and Figure 9 , in this case, it is suitable for a smaller carrier 2.

[0099] When the vehicle 2 is large in size, that is, large in length and width, it is easy for the vehicle 2 to shake when being pushed up from the bottom of the vehicle 2. Therefore, the movable end of the lifting mechanism 6 can be arranged on both sides of the lower surface of the vehicle 2.

[0100] Specifically, both sides of the vehicle 2 exceed both sides in the length direction of the streamline 5, that is, the movable ends of the lifting mechanism 6 are arranged on both sides in the length direction of the streamline 5. When the vehicle 2 is lifted from both sides by the movable ends of the lifting mechanism 6, the surface of the streamline 5 can still convey the vehicle 2. That is, to ensure that the streamline 5 is unobstructed and does not accumulate during hot pressing, a cylinder is arranged on both sides of the pressing station. When the streamline 5 conveys the vehicle 2 to the pressing station, the movable end of the cylinder contacts the lower surface of the product, and then the product is lifted to a suitable position. Subsequently, the streamline 5 conveys the remaining vehicles 2 to the next station.

[0101] In some specific embodiments, the streamline 5 is two linear guide rails 26 arranged on the upper surface of the workbench 1.

[0102] Since the linear guide rail 26 conveys the vehicle 2 in a straight line, it can prevent the vehicle 2 from shifting during the conveyance by the linear guide rail 26.

[0103] In some specific embodiments, an adjusting guide rail 27 connected to the upper surface of the workbench 1 is provided at the bottom of the streamline 5 for adjusting the width between the linear guide rails 26.

[0104] Refer to Figure 7 and Figure 8 , one of the two linear guide rails 26 is fixedly arranged, and the other is arranged on the adjusting guide rail 27. When the vehicle 2 encountered is relatively wide, the movable linear guide rail 26 is adjusted through the adjusting guide rail 27 so that the width between the two linear guide rails 26 is adjusted to a suitable position.

[0105] Working principle: Refer to Figures 1 - 12 As shown below, two loading positions 29, two up-and-down movement modules 11 and two stabilizing films 18 are taken as examples for illustration:

[0106] Select products of the same type or different types to be carried according to the number of the loading positions 29. Then, place the vehicle 2 loaded with the products on the streamline 5. Subsequently, the vehicle 2 is transferred by the streamline 5 to the pressing station. After that, the vehicle 2 stops moving. Then, the movable end of the lifting mechanism 6 will push the vehicle 2 to rise until each product fits against the horizontal section 9 of each stabilizing film 18. Then, each up-and-down movement module 11 will push the pressing head 12 thereon to apply a set range of pressure and temperature to the surface of the horizontal section 9 in contact with the tape.

[0107] When the movable end of the lifting mechanism 6 pushes the carrier 2 to rise until each product fits against the horizontal section 9 of each stabilizing film 18, the movable ends of the two up-and-down movement modules 11 will simultaneously descend and respectively push the corresponding mounting blocks 13 downward. After that, the two mounting blocks 13 will drive the corresponding pressing heads 14 to respectively press on the surfaces of the two horizontal sections 9 that are adhered to the tape. At this time, each pressing head 14 will apply a certain temperature to the surface of the horizontal section 9 by itself, and at the same time, each pressing head 14 will also receive the pressure from the corresponding counterweight 15, so that the surface of the horizontal section 9 will also be under pressure. In this way, the purpose of hot pressing the product is completed.
