Description

Technical Field

[0001] The present invention relates to an automated production device, and particularly to an automated production device for in-mold stamping and chip mounting in a composite mold. Background Art

[0002] With the increase in labor costs, enterprises introduce automated production equipment into the production manufacturing process to replace labor-intensive manual operations. The economic benefits brought by automated production equipment have become one of the keys to creating enterprise value and enhancing industrial competitiveness. For example, automated production equipment is applied to integrate the stamping manufacturing process and assembly in the production line, and for the cumbersome processing procedures, high-efficiency control is carried out through process integration.

[0003] For example, in a general stamping process, a complete stamping product must be completed by combining multiple sets of molds or multiple engineering conversions. After the thin-sheet-shaped coil material is stamped into a semi-finished product, it must go through multiple line changes and transfers in order to be moved to other workstation equipment for subsequent processing operations, such as attaching insulating sheets to each semi-finished product. Thus, if all rely on manual management of each stage of the manufacturing process, the waiting period for line changes and in-transit inventory will lead to a reduction in operating efficiency, increase material costs, and extend the delivery period. Summary of the Invention

[0004] An object of the present invention is to provide an automated production device for in-mold stamping and chip mounting in a composite mold to improve production efficiency and solve the difficulties mentioned in the above prior art.

[0005] An embodiment of the present invention provides an automated production device for in-mold stamping and chip mounting, which includes a punch strip feeding device, a continuous stamping die set, a punch strip feeding device, and an insulating sheet feeding device. The punch strip feeding device is used to continuously feed a stamping strip in a first direction. The continuous stamping die set includes a stamping lower die base and a stamping upper die base. The stamping lower die base includes a lower template and a strip feeding area. The strip feeding area is connected to the lower template and has a gap with the lower template to allow the stamping strip to be fed into it. The stamping upper die base includes an upper template and a plurality of punches. The upper template is vertically movable on the lower template. These punches are located on the stripper plate of the upper template facing the lower template, and are used to synchronously punch out a plurality of semi-finished products arranged in sequence on the stamping strip when the upper template closes the lower template. The insulating sheet feeding device is connected to the lower template and is used to continuously feed an insulating sheet strip in a second direction to the continuous stamping die set. The insulating sheet strip includes a main strip and a plurality of insulating sheet groups. The main strip passes through between the lower template and the stamping strip, and these insulating sheet groups are detachably located on the main strip and are respectively sticky. When the upper template and the lower template close, and one of the semi-finished products overlaps one of the insulating sheet groups, the stamping strip is pressed down by the upper template to the insulating sheet strip, so that the overlapping insulating sheet group and the semi-finished product are pasted to each other. When the upper template and the lower template open, the stamping lower die base tears the stamping strip away from the insulating sheet strip, so that the insulating sheet group pasted to the semi-finished product is torn away from the main strip.

[0006] Thus, through the above-described architectures of the various embodiments, the present invention does not need to specifically move the semi-finished products to other workstations for chip mounting, and can synchronously complete the chip mounting manufacturing process during the stamping manufacturing process. Therefore, not only can the operation efficiency be improved, but also the operation cost can be reduced and the delivery period can be shortened.

[0007] The above is only used to elaborate on the problems to be solved by the present invention, the technical means for solving the problems, and the effects produced thereby. The specific details of the present invention will be introduced in detail in the following embodiments and related drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0086] The following will disclose multiple embodiments of the present invention with the accompanying drawings. For the sake of clear illustration, many practical details will be described together in the following narration. However, it should be understood that these practical details are not used to limit the present invention. That is to say, in the embodiments of the present invention, these practical details are non-essential. In addition, for the purpose of simplifying the drawings, some conventional existing structures and elements will be shown in a simple schematic manner in the drawings.

[0087] Figure 1A perspective view of an automated production apparatus 10 for in-mold stamping and chip mounting according to an embodiment of the present invention in an open mold state. Figure 2 Shows Figure 1 A perspective view of the automated production apparatus 10 in a closed mold state. Figure 3 Shows Figure 1 An exploded view of the upper / lower dies of the progressive stamping die set 100. As Figure 1 And Figure 2 Shown, in this embodiment, the automated production apparatus 10 includes a progressive stamping die set 100, a punch strip feeding device 400, an insulating sheet feeding device 500, and a programmable logic controller system (hereinafter referred to as the PLC system) 700. The punch strip feeding device 400 continuously feeds a thin plate-shaped stamping strip 440 in a first direction D1 and drives the stamping strip 440 to advance by a first step unit each time.

[0088] The progressive stamping die set 100 includes a stamping upper die base 200 and a stamping lower die base 300 that can be opened / closed with each other. That is, a press provides power to drive the stamping upper die base 200 and the stamping lower die base 300 to repeatedly perform closing and opening actions along a stamping stroke direction H, so that the two perform closing and opening with each other under the guidance of a guide pillar 390. The stamping lower die base 300 includes a lower template 310 and a strip feeding area 320 ( Figure 3 ). The strip feeding area 320 is connected to the lower template 310 and maintains a gap with the die surface 311 of the lower template 310. The strip feeding area 320 extends in the first direction D1 to serve as a feeding and advancing path for the stamping strip 440. The stamping upper die base 200 includes an upper template 210 and a plurality of punches 220 ( Figure 3)。The upper template 210 is vertically movable and located on the die surface 311 of the lower template 310. These punches 220 are arranged on the stripper plate 211 of the upper template 210 facing the lower template 310, and are arranged in sequence along the first direction D1. Each time the upper template 210 and the lower template 310 are closed, these punches 220 can perform a single punching step along the stamping stroke direction H to synchronously punch out a plurality of semi-finished products 441 with different completion progress at different positions of the stamping strip 440, and these semi-finished products 441 with different completion progress are arranged in a single column in sequence along the first direction D1. Among these semi-finished products 441 that have completed different processes, the last semi-finished product 441 is the component to be pasted 442. In this embodiment, each semi-finished product 441 is designed to be sequentially formed on the stamping strip 440 by multiple stamping processes. For example, the above-mentioned component to be pasted 442 is a CPU bracket, and is sequentially completed by multiple stamping processes including punching, contour stamping, and bracket separation. It should be understood that each time the stamping strip 440 advances by a first pitch unit, the stamping strip 440 advances by the distance of one semi-finished product 441 each time within the strip feeding area 320.

[0089] The insulating sheet feeding device 500 is connected to the lower template 310, and is used to continuously feed an insulating sheet strip 600 along a second direction D2 to the continuous stamping die set 100, and drive the insulating sheet strip 600 to advance by a second pitch unit each time. In a specific embodiment, the second direction D2 intersects with the first direction D1, for example, they are orthogonal to each other. More specifically, the insulating sheet strip 600 is a multi-layer structure, including a main strip 610 and a plurality of insulating sheet groups 630. The main strip 610 passes through between the lower template 310 and the stamping strip 440. These insulating sheet groups 630 are arranged in a single column in sequence on the main strip 610.

[0090] It should be understood that each time the insulating sheet strip 600 advances by the second pitch unit, the insulating sheet advances one insulating sheet group 630 each time into the area where the stamping strip 440 and the insulating sheet strip 600 overlap each other.

[0091] The operation of the PLC system 700 includes monitoring, controlling the machine and the electrical system, running the process, controlling the working speed, and integrally electrically connecting to the automated production equipment 10, the continuous stamping die set 100, the punch strip feeding device 400, and the insulating sheet feeding device 500. The punch strip feeding device 400 and the insulating sheet feeding device 500 work in cooperation with each other at the correct timing.

[0092] Figure 4 Shown Figure 1 is a longitudinal partial cross-sectional view of the insulating sheet strip 600. As Figure 4As shown, the insulating sheet tape 600 further includes a release paper tape 620. One side of each insulating sheet group 630 is adhesive. These insulating sheet groups 630 are separably stacked between the main material tape 610 and the release paper tape 620, and these insulating sheet groups 630 are arranged at intervals in a single row along the second direction D2. These insulating sheet groups 630 are independently tearable from the main material tape 610. Each insulating sheet group 630 includes a Mylar sheet 632, an upper adhesive layer 631, a lower adhesive layer 633, and a Mylar release paper 634. The upper adhesive layer 631 is sandwiched between the Mylar sheet 632 and the release paper tape 620, and the release paper tape 620 can be torn off from these insulating sheet groups 630 by an external force. The lower adhesive layer 633 is directly located on the side of the Mylar sheet 632 facing away from the release paper tape 620, and the Mylar release paper 634 can be torn off from the lower adhesive layer 633 by an external force. The Mylar release paper 634 is sandwiched between the lower adhesive layer 633 and the main material tape 610. The Mylar release paper 634 is attached to the main material tape 610 through a weak adhesive layer 635.

[0093] It should be understood that the main material tape 610 carries the insulating sheet groups 630 by means of adhesive. However, the present invention is not limited thereto. In other embodiments, the main material tape 610 may not require adhesive, but may carry the insulating sheet groups 630 by means of static electricity.

[0094] Thus, please refer to Figure 2 、 Figure 7 and Figure 8 simultaneously. The die surface 311 of the stamping lower die base 300 has a female die 381. Whenever the stamping tape 440 and the insulating sheet tape 600 run in the female die 381 respectively, one insulating sheet group 630 and the to-be-pasted piece 442 overlap each other, and when the second optical sensors 370 ( Figure 7 ) of each of the two groups overlap and align with the first feature sensing point 640 ( Figure 8 ) and then send out signals, the PLC system 700 receives the signals and sends a die-closing signal to the automatic production equipment 10. When the upper template 210 and the lower template 310 are closed along the stamping stroke direction H, the corresponding insulating sheet group 630 on the insulating sheet tape 600 can be pasted on the to-be-pasted piece 442 through the upper adhesive layer 631 to form a finished product 445 ( Figure 1 ).

[0095] On the contrary, as Figure 2As shown, whenever the stamping upper die base 200 rises relative to the stamping lower die base 300 to its original position, that is, when the upper template 210 and the lower template 310 are opened, the stamping lower die base 300 pushes the stamping strip 440 away from the insulating sheet strip 600. Since the adhesive force of the upper adhesive layer 631 is greater than the adhesive force of the weak adhesive layer 635 of the Mylar release paper 634, the insulating sheet group 630 pasted to the to-be-pasted piece 442 can be independently torn off from the main material strip 610. Therefore, the punch strip feeding device 400 and the insulating sheet feeding device 500 can continue to feed the corresponding stamping strip 440.

[0096] More specifically, as Figure 1 shown, the punch strip feeding device 400 includes a stamping strip winding and placing bracket 410, a flattening machine 420 and two feeding rollers 430. The flattening machine 420 is located between the stamping strip winding and placing bracket 410 and the feeding rollers 430. The stamping strip 440 is wound around the stamping strip winding and placing bracket 410 to feed the stamping strip 440 into the continuous stamping die set 100. These two feeding rollers 430 are located between the stamping strip winding and placing bracket 410 and the continuous stamping die set 100, and are used to clamp the stamping strip 440 between these feeding rollers 430 and make the stamping strip 440 continuously advance in the first direction D1. In this embodiment, these two feeding rollers 430 are driven by a power device (not shown in the figure), so that these feeding rollers 430 rotate in opposite directions to each other to continuously push the stamping strip 440 in the first direction D1, and these feeding rollers 430 push the stamping strip 440 forward by a first step unit at equal steps at each time interval (for example, 0.5 to 0.7 seconds). However, the present invention is not limited thereto.

[0097] In addition, the stamping lower die base 300 further includes a plurality of stamping strip lifting and guiding pins, hereinafter referred to as the first lifting and guiding pins 321 and the second lifting and guiding pins 322 ( Figure 3 ). These first lifting and guiding pins 321 are respectively arranged on the die surface 311 of the lower template 310 and are arranged at intervals in a single row along the first direction D1. Each first lifting and guiding pin 321 is pivotally arranged on the lower template 310. These second lifting and guiding pins 322 are respectively arranged on the die surface 311 of the lower template 310 and are arranged at intervals in a single row along the first direction D1. Each second lifting and guiding pin 322 is pivotally located on the lower template 310. Since these stamping strip lifting and guiding pins (that is, these second lifting and guiding pins 322 and the first lifting and guiding pins 321) are arranged at intervals opposite to each other along the first direction D1, the second lifting and guiding pins 322 and the first lifting and guiding pins 321 together define the above-mentioned strip running area 320. The first lifting and guiding pins 321 and the second lifting and guiding pins 322 respectively contact two opposite sides of the stamping strip 440, so that the stamping strip 440 can be suspended between the second lifting and guiding pins 322 and the first lifting and guiding pins 321 and stably advance in the first direction D1.

[0098] Figure 5A Partial transverse sectional view of the lifter guide pin assembly of the continuous stamping die set 100. Figures 5B to 5D It is Figure 5A Schematic diagram of the continuous operation of closing the die to opening the die for the area M of. As Figure 3 And Figure 5A shown, the stamping upper die base 200 further includes a plurality of first relief holes 230 and a plurality of second relief holes 240. These first relief holes 230 are respectively arranged on the stripper plate 211 of the upper template 210 and are spaced along the first direction D1. These second relief holes 240 are respectively arranged on the stripper plate 211 of the upper template 210 and are spaced along the first direction D1. These first lifter guide pins 321 are respectively arranged corresponding to these first relief holes 230, these second lifter guide pins 322 are respectively arranged corresponding to the second relief holes 240, and each first lifter guide pin 321 is composed of one lifter spring 323 and a set screw 324 in cooperation, and each second lifter guide pin 322 is composed of one lifter spring 323 and a set screw 324 in cooperation. The function of the lifter spring 323 is to maintain the elastic space for the first / second lifter guide pins 321 / 322 to rise and fall, and after positioning the stamping strip 440, continue to press down to close the die surface 311, and press the chip to be pasted 442 of the stamping strip 440 onto the insulation sheet group 630 ( Figure 5C ).

[0099] As Figures 5B to 5C shown, when the stamping machine closes the upper template 210 downward, each first lifter guide pin 321 just extends into the corresponding first relief hole 230, and each second lifter guide pin 322 just extends into the corresponding second relief hole 240. At the same time, the insulation sheet group 630 is adhered to the chip to be pasted 442.

[0100] On the contrary, as Figures 5C to 5D shown, when the stamping machine opens the upper template 210 upward, each first lifter guide pin 321 disengages from the corresponding first relief hole 230, and each second lifter guide pin 322 disengages from the corresponding second relief hole 240. Due to the elastic restoring force of the lifter spring 323, the corresponding first / second lifter guide pins 321 / 322 are pushed upward, so that the stamping strip 440 is pushed up and floated along with the first / second lifter guide pins 321 / 322. At this time, the insulation sheet group 630 that has been adhered to the chip to be pasted 442 is torn off from the main strip 610, and thus adheres to the chip to be pasted 442 of the stamping strip 440 ( Figure 5D ).

[0101] Figure 6 Shows Figure 1 Side view of the insulation sheet feeding device 500 of. As Figure 1 And Figure 6As shown, the insulating sheet feeding device 500 includes a feeding main body 510, an insulating sheet strip unwinding wheel 520, a main strip winding wheel 530, and a release paper winding wheel 540. The feeding main body 510 includes a housing 511 and a control unit 512. The housing 511 of the feeding main body 510 is located on one side of the stamping lower die base 300. The insulating sheet strip unwinding wheel 520 is pivotally connected to the housing 511 of the feeding main body 510 for gradually rotating the insulating sheet strip 600 presented as a first coil 521, so as to continuously feed the insulating sheet strip 600 onto the die surface 311 of the lower template 310. The insulating sheet strip unwinding wheel 520 feeds out the insulating sheet strip 600 according to a first rotation speed. The main strip winding wheel 530 is pivotally connected to the housing 511 of the feeding main body 510. The main strip winding wheel 530 cooperates with the first rotation speed of the insulating sheet strip unwinding wheel 520 to gradually recover and wind the part of the main strip 610 passing between the lower template 310 and the stamping strip 440 into a second coil 531. The main strip winding wheel 530 winds up the main strip 610 according to a second rotation speed. The release paper winding wheel 540 is pivotally connected to the feeding main body 510 to gradually recover and wind the release paper tape 620 into a third coil 541.

[0102] In addition, the insulating sheet feeding device 500 includes a first tension sensing roller 550, a second tension sensing roller 560, and a third tension sensing roller 570. The first tension sensing roller 550 is pivotally connected to the housing 511 of the feeding main body 510 for guiding the moving direction of the insulating sheet strip 600 and sensing the current first tension of the insulating sheet strip 600. The second tension sensing roller 560 is pivotally connected to the feeding main body 510 for guiding the part of the main strip 610 passing between the lower template 310 and the stamping strip 440 and sensing the current second tension of the main strip 610. The third tension sensing roller 570 is pivotally connected to the feeding main body 510 for guiding the moving direction of the release paper tape 620 and sensing the current third tension of the release paper tape 620. The control unit 512 of the feeding main body 510 is electrically connected to the first tension sensing roller 550, the second tension sensing roller 560, and the third tension sensing roller 570 for adjusting the first rotation speed of the main strip winding wheel 530 according to the first tension, adjusting the second rotation speed of the insulating sheet strip unwinding wheel 520 according to the second tension, and adjusting the third rotation speed of the release paper winding wheel 540 according to the third tension.

[0103] The stamping lower die base 300 includes an insulating strip holder 330 and a release paper separating plate 340. The insulating strip holder 330 is connected to the die surface 311 of the lower template 310. The main material strip winding wheel 530 and the insulating strip feeding wheel 520 are both located on the same side of the stamping lower die base 300, and are used to carry the main material strip 610 and these insulating strip groups 630. The release paper separating plate 340 is located on the insulating strip holder 330. The release paper separating plate 340 has a guiding inclined surface, and the guiding inclined surface is used to guide the release paper tape 620 to be sent to the release paper winding wheel 540.

[0104] In this way, when the insulating strip feeding wheel 520 outputs an insulating strip 600, the advancing tension of the insulating strip 600 is adjusted by the first tension sensing roller 550, and the insulating strip 600 is flattened by the flattening roller 551, so that the insulating strip 600 can advance smoothly and quickly on the insulating strip holder 330. After the main material strip 610 carrying the insulating strip group 630 advances between the female die 381 and the stamping strip 440, it is rotated 180 degrees by a rotating roller 590 to change the advancing direction of the main material strip 610, and then passes under the stamping lower template 310. Then, through the mutual response of the first tension sensing roller 550 and a pair of traction rollers 580, after adjusting the tension of the main material strip 610, it is finally collected on the main material strip winding wheel 530. In addition, before the insulating strip 600 enters between the insulating strip holder 330 and the stamping strip 440, the release paper tape 620 is separated by the release paper separating plate 340, and under the traction of the release paper winding wheel 540 and the mutual response of the first tension sensing roller 550, the release paper tape 620 is gradually torn off to expose the main material strip 610 and these insulating strip groups 630 thereon, and they are recycled.

[0105] When the insulating strip 600 is unwound and wound, the coil diameter of the coil will continuously change, and the tension of the coil will continuously change with the change of the coil diameter. In addition, in the state where the insulating strip 600 is advancing in a rolling motion, the change of the tension can cause the strip to be in a stretched or tightened state, and there may be a situation of tape jamming or material extrusion. Therefore, relying solely on the synchronous transmission of the unwinding and winding wheels cannot keep the tension of the above-mentioned strip always stable and consistent, and it is necessary to control the tension of the coil of the strip.

[0106] In this way, in order to avoid wrinkles, slack, unsmooth rolling, and even breakage of the above-mentioned first coil 521 and second coil 531 caused by the time difference between the insulating strip feeding wheel 520 and the main material strip winding wheel 530, the control unit 512 of the feeding main machine 510 further adjusts the first rotation speed and the first tension of the main material strip winding wheel 530 according to the change of the coil diameter of the first coil 521, and adjusts the second rotation speed and the second tension of the insulating strip feeding wheel 520 according to the change of the coil diameter of the second coil 531.

[0107] In addition, the automated production equipment 10 further includes an image sensor 800. The image sensor 800 captures an image of the insulating strip 600 and detects the insulating strip 600 through image comparison.

[0108] Figure 7 Shown Figure 3 The front view of the female die of the lower template 310. Figure 8 For the insulating sheet attachment process, shown Figure 3 The partial enlarged view of the lower template 310 viewed directly in the direct viewing direction S. As Figure 7 And Figure 8 As shown, the insulating strip 600 has a plurality of first feature sensing points 640. These first feature sensing points 640 are periodically arranged at intervals along the second direction D2 in sequence, and each first feature sensing point 640 is located on the main strip 610, between any two adjacent insulating sheet groups 630. In this embodiment, the first feature sensing point 640 is a sensing point on the main strip 610. However, the present invention is not limited thereto. In other embodiments, the first feature sensing point 640 may also be a light-shielding pattern.

[0109] The stamping strip 440 has a plurality of identification feature groups 443, and these identification feature groups 443 are arranged equidistantly in sequence along the first direction D1 on the stamping strip 440. Each identification feature group 443 includes two second feature sensing points 444, and the patch 442 to be attached is located between these two second feature sensing points 444 of the same identification feature group 443. In this embodiment, the second feature sensing point 444 is a sensing point of the stamping strip 440 (such as a through hole or a printed pattern). However, the present invention is not limited thereto. In other embodiments, the second feature sensing point 444 may also be a light-shielding pattern.

[0110] The stamping lower die base 300 further includes a first light sensor 360 and two second light sensors 370 ( Figure 7 ). The first light sensor 360 is located in the female die 381 of the lower template 310, between the strip feeding area 320 and the insulating strip support 330. These second light sensors 370 are arranged at intervals on the die surface 311 of the lower template 310 and are located in the overlapping area of the stamping strip 440 and the insulating strip 600. In this embodiment, the first light sensor 360 and the two second light sensors 370 are respectively fiber optic sensors. However, the present invention is not limited to the type of light sensors.

[0111] In this way, when the insulating strip 600 advances toward the female die 381 of the lower template 310 and the first light sensor 360 senses and aligns with the sensing point on the main strip 610, the first light sensor 360 sends a feedback signal to the PLC system 700. Therefore, the PLC system 700 controls the stamping machine to drive the upper template 210 and the lower template 310 to perform die opening according to this feedback signal.

[0112] Furthermore, when the stamping strip 440 advances within the strip feeding area 320 of the strip, and these two second optical sensors 370 respectively sense and align with the second feature sensing points 444 of the stamping strip 440 through the main strip 610, since the component to be pasted 442 overlaps one of the insulating sheet groups 630, thus, the PLC system 700 accordingly makes the stamping machine drive the upper template 210 and the lower template 310 to perform mold closing.

[0113] Back Figure 1 And Figure 2 As shown, the stamping lower die base 300 further includes an ejecting device 380. The ejecting device 380 is extendably located on the die surface 311 of the lower template 310 and within the strip feeding area 320 of the strip. Thus, when the upper template 210 and the lower template 310 are in mold opening, the PLC system 700 controls the ejecting device 380 to respectively extend from the die surface 311 of the lower template 310, so that the ejecting device 380 ejects the finished product 445 located on the die surface 311 of the lower template 310.

[0114] As Figure 1 shown, the stamping lower die base 300 further includes a discharging guiding portion 312 (such as an inclined surface). The discharging guiding portion 312 of the stamping lower die base 300 is located at one end of the die surface 311 of the lower template 310 away from the strip feeding device 400 of the punching machine. The stamping upper die base 200 further includes a plurality of cutting punches 250. These cutting punches 250 are located on the stripping plate 211 of the upper template 210. Thus, when the upper template 210 and the lower template 310 are in mold closing, the cutting punches 250 immediately completely punch off the component to be pasted 442 with the insulating sheet group 630 pasted thereon from the stamping strip 440, and then let the cut component to be pasted 442 fall into a good product collection area through the discharging guiding portion 312.

[0115] Thus, through the architectures of the above embodiments, the present invention does not need to specially transfer the semi-finished product to other workstations for pasting, and can synchronously complete the pasting manufacturing process during the stamping manufacturing process. Therefore, not only can the operation efficiency be improved, but also the operation cost can be reduced and the delivery period can be shortened.

[0116] Finally, in the above-disclosed embodiments, they are not used to limit the present invention. Any person familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention, and all can be protected by the present invention. Therefore, the protection scope of the present invention should be defined by the appended claims.
