Abstract
Description
Technical Field
[0001] This invention belongs to the field of SMT, and in particular relates to an SMT tape splicing and assembly device. Background Technology
[0002] Currently, the factory warehouse uses a "unified recycling and centralized stacking" model for process waste materials generated from the SMT production line (such as unused tape reels, bulk surplus materials, and skipped-count materials), lacking refined classification and labeling based on material code, batch, quantity, and status (can be directly used / requires re-inspection / awaiting scrap). This leads to: Physical aspects: Waste materials are mixed and piled up in a messy manner, with unclear labels and difficulty in finding them; the occupancy rate of storage space is inflated, and the effective storage space utilization rate is insufficient. At the system level: Creating a separate ERP / MES SKU for each roll of leftover material resulted in a large number of low-turnover, non-standard, and long-tail material codes in the system, which severely diluted the quality of master data; From a business perspective: When the production line needs to replenish materials urgently, it requires manual searching and secondary confirmation, with an average response delay of 2.3 hours, which restricts flexible production and rapid line changeover capabilities.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.
[0020] like Figure 1-2 As shown, one embodiment of the present invention is: an SMT tape splicing and assembly device, which is provided with a frame, and a feeding mechanism 1, a receiving mechanism 2 and a receiving mechanism 3 are arranged sequentially from front to back on the upper surface of the frame; the receiving mechanism 2 includes a swaddling receiving device 20 arranged on the left side of the middle part of the frame and a receiving resistance measuring device 21 arranged on the right side of the middle part of the frame. The feeding mechanism 1: transfers the tape inside the magazine to the receiving mechanism 2; The receiving mechanism 2 splices the tail of the received tape with the head of the next tape, measures the resistance value, and cuts the tape at a designated position. The ferry receiving device 20: transmits the tape from the receiving resistance measuring device 21 to the receiving mechanism 3; The receiving mechanism 3 temporarily stores the assembled material strips as an intermediate transition, and finally assembles the temporarily stored intermediate material strips into a complete material tray with a reasonable head-to-tail order.
[0021] It should be noted that the feeding mechanism 1 has the same structure as the feeding device in application number CN202510707723.3, patent name: semi-automatic tray closing mechanism; several individual material trays are set in the material tray frame, and the material strips on the individual material trays are transferred to the receiving mechanism 2.
[0022] Implementation 2: such as Figure 3-9The material receiving and resistance measuring device 21 is equipped with a splicing frame, a transmission track 22, a splicing device 23, a resistance measuring device 24, a heating device 25, and a shearing device 26. A braiding frame is provided on the right side of the middle of the frame, and a transmission track 22 is provided on the left side of the middle of the frame; a splicing device 23 is provided at the front end inside the braiding frame, and a resistance measuring device 24 and a heating device 25 are provided close to the splicing device 23; the shearing device 26 is close to the rear side wall of the braiding frame. The splicing device 23 is equipped with a hot melt adhesive film conveying structure, inclined push blocks 235, and a peeling structure 236. The hot melt adhesive film conveying structure includes an adhesive film disc 231, a recovery roller 233, and guide rollers 232. One end of the adhesive film belt 234 passes sequentially through the adhesive film disc 231 and a corresponding number of guide rollers 232, and is finally recovered by the recovery roller 233. The two inclined push blocks 235 are arranged on both sides of the adhesive film belt 234 where the adhesive film has not been detached. The inclined push blocks 235 are installed at an angle, and the angle is close to the side wall of the adhesive film belt 234. The distance between the inclined ends of the two inclined push blocks 235 is less than the width of the adhesive film belt 234.
[0023] It should be noted that the distance between the two inclined push blocks affects the width of the adhesive film 234, causing the two side walls of the adhesive film 234 to be squeezed towards the middle, thus making it easier for the adhesive film to detach from the adhesive film 234.
[0024] The peeling structure 236 is installed at the bottom of the adhesive film strip 234 after the adhesive film is separated; the peeling structure 236 includes a peeling slide 2361, a wedge block 2362, a swing plate 2363, a front plate 2365, a fixing rod, and a spring seat 2364; one end of the fixing rod is fixed to the braiding frame, and the other end of the fixing rod passes through a pre-set hole in the swing plate 2363, so that the swing plate 2363 is fixed to the braiding frame; the other side of the swing plate 2363 is fixed to one end of the front plate 2365, and the other end of the front plate 2365 extends to the front end of the adhesive film strip 234; The peeling slide 2361 is fixed on the side wall of the transmission track 22, and the bottom of the wedge block 2362 is fixed on the slider of the peeling slide 2361. The opening of the wedge block 2362 faces the side of the swing plate 2363. The spring seat 2364 is disposed on the lower surface of the connection between the swing plate 2363 and the front plate 2365. A spring is installed on the spring seat 2364, and the top of the spring is in contact with the bottom of one side of the swing plate 2363.
[0025] It should be noted that when the adhesive tape 234 is arched, the front plate 2365 is in contact with the lower surface of the adhesive tape 234. At this time, the peeling slide 2361 works, and the slide moves the wedge block 2362 closer to one side of the swing plate 2363. With the fixed rod as the center, one side of the swing plate 2363 is raised, and the other side of the swing plate 2363 is lowered accordingly. The spring of the spring seat 2364 retracts, so that the adhesive tape is attached to the surface of the tape to be spliced. The peeling slide 2361 works again, and the slide moves the wedge plate away from one side of the swing plate 2363. The spring of the spring seat 2364 also simultaneously lifts the other side of the swing plate 2363.
[0026] The peeling structure 236 further includes a lifting structure 237, which is located near the end of the front panel 2365 and on the transmission track 22. The lifting structure 237 includes a lifting plate and a lifting cylinder. The lifting cylinder is installed at the bottom of the transmission track 22, and the output end of the lifting cylinder passes through the transmission track 22 and is fixed to the bottom of the lifting plate.
[0027] It should be noted that in order to place the adhesive film at the splicing point of the tape and ensure that the adhesive film is completely adhered to the splicing point, not only does the front panel 2365 need to place the adhesive film at the splicing point, but the lifting cylinder also needs to work simultaneously to push the top of the lifting plate to press against the splicing point of the tape, so that the adhesive film can adhere more tightly to the splicing point.
[0028] The resistance measuring device 24 includes a resistance measuring cable chain 240, a resistance measuring connecting plate, a resistance measuring lifting cylinder 241, a resistance measuring translation cylinder 242, an L-shaped resistance measuring fixing plate 244, a resistance measuring sliding assembly (shearing needle seat, shearing slider), a first probe 245 and a second probe 246. The resistance-measuring cable chain 240 is fixed to the upper part of the braided frame; one end of the resistance-measuring connecting plate is connected to the movable end of the cable chain, the other end of the resistance-measuring connecting plate is fixed to one side of the resistance-measuring fixing plate 244, the other side of the resistance-measuring fixing plate 244 is fixed to the base of the resistance-measuring lifting cylinder 241, the output end of the resistance-measuring lifting cylinder 241 is fixed to one side of the upper end of the resistance-measuring fixing plate 244, the resistance-measuring translation cylinder 242 is fixed to one side of the lower end of the resistance-measuring fixing plate 244, the movable end of the resistance-measuring translation cylinder 242 drives the resistance-measuring sliding assembly to perform translational movement, the first probe 245 is fixed to the tail of the lower end of the resistance-measuring fixing plate 244, and the second probe 246 is fixed to the resistance-measuring sliding assembly. The resistance measuring sliding assembly is provided with a sliding probe seat 243 and a sliding block; the other side of the resistance measuring fixing plate 244 is provided with a sliding groove, one end of the sliding probe seat 243 is fixed to the movable end of the resistance measuring translation cylinder 242, and the other end of the sliding probe seat 243 is fixed to the sliding block. The sliding block slides in cooperation with the sliding groove, and the second probe 246 is fixed on the surface of the sliding block, so that the first probe 245 and the second probe 246 are on the same horizontal plane.
[0029] It should be noted that when it is necessary to measure the splice of the tape, the drag chain will drive the resistance measuring connecting plate to move forward. The resistance measuring lifting cylinder 241 will work to drive the resistance measuring fixing plate 244 to move down to the designated position. At this time, the gap between the first probe 245 and the second probe 246 is the width of the tape resistance measurement. The resistance measuring translation cylinder 242 will drive the sliding needle seat 243 to move closer to the position of the first probe 245. The sliding needle seat 243 will drive the second probe 246 on the sliding block to move closer to the position of the first probe 245, thereby realizing the measurement of the splice of the tape.
[0030] The heating device 25 includes a heating bracket, a heating linear module, a heating head 255, a first slide rail fixing block 252, a second slide rail fixing block 254, a first limiting block 256, a second limiting block, and a limiting spring 253; The heating bracket is fixed on the braided frame, the heating linear module is fixed on the heating bracket, the first slide rail fixing block 252 slides on the heating linear module; the second slide rail fixing block 254 is fixed on the surface of the heating slider of the heating linear module; one end of the limiting spring 253 is fixed to the lower part of the first slide rail fixing block 252, and the other end of the limiting spring 253 is fixed to the upper part of the second slide rail fixing block 254; the first limiting block 256 is fixed at a preset position on the heating linear module, and the second limiting block is fixed at a set position on the second slide rail fixing block 254; the first limiting block 256 and the second limiting block form a limiting device.
[0031] It should be noted that, in order to make the splice of the tape more secure, after the tape is measured, it needs to be heated to make it more stable and secure; the heating linear module drives the second slide rail fixing block 254 to move downward. When it reaches the preset position, the heating head 255 heats the splice so that the adhesive film can better adhere to the splice. To prevent the heating head 255 from being too close to the surface of the tape or from being too hot, a first limiting block 256 and a second limiting block are respectively installed on the heating linear module and the second slide rail fixing block 254. The two limiting blocks are combined to form a limiting device. When the first limiting block 256 contacts the second limiting block, the second slide rail fixing block 254 stops moving, thereby ensuring the descent distance of the heating block. When the second slide rail fixing block 254 moves upward, the limiting spring 253 is installed between the first slide rail fixing block 252 and the second slide rail fixing block 254, thereby achieving the effect of the upper limit of the second slide rail fixing block 254.
[0032] Shearing device 26 includes a shearing bracket, a shearing cylinder 261, a shearing mounting plate, a compression spring, a first shear fixing plate 263, a second shear fixing plate 264, an upper blade 265, a lower blade 266, a shaft pin 267, and a shear pusher 262. The bottom of the shearing bracket is fixed to the braiding frame. The shearing cylinder 261 is installed at one end of the shearing bracket. The output end of the shearing cylinder 261 is fixed to one end of the shearing pusher 262. The bottom of the first shearing fixing plate 263 is fixed to the slider of the linear guide rail of the shearing bracket. One end of the shaft pin 267 is fixed to the outside of the first shearing fixing plate 263. The other end of the shaft pin 267 passes through the first through hole of the first shearing fixing plate 263, the second through hole of the upper blade 265, the third through hole of the lower blade 266, and the fourth through hole of the second shearing fixing plate 264 in sequence. The upper blade 265 is fixed to the inside of the first shearing fixing plate 263. The bottom end of the lower blade 266 is provided with an arc-shaped notch. The inner side wall of the shearing pusher 262 is provided with a support column 268.
[0033] It should be noted that: In the initial state: the notch of the lower blade 266 is fitted onto the support column 268, and the lower blade 266 is tilted backward. At this time, the lower blade 266 and the upper blade 265 are in an interlocking state and cannot cut. When the shearing cylinder 261 pushes the shear pusher 262 forward, in the final state, the notch of the lower blade 266 rotates on the support column 268, causing the lower blade 266 to tilt forward. At this time, the lower blade 266 and the upper blade 265 are in a non-engaged state. Intermediate state: The process of the lower blade 266 and the upper blade 265 changing from a non-engaged state to an engaged state is the shearing state.
[0034] Example 3: As Figure 10 As shown: the transfer receiving device 20 includes a transfer base 203, a transfer conveyor track 202, a belt drive power assembly 204, and a transfer cable chain module 201; the transfer cable chain module 201 is fixed to one side of the frame, and the moving end of the transfer cable chain module 201 is fixed to the transfer base 203; the bottom of the transfer conveyor track 202 is fixed to the top of the transfer base 203; the belt drive power assembly 204 is set at a preset position on the transfer conveyor track 202; the belt drive power assembly includes a belt conveyor structure set below the transfer conveyor track; the belt conveyor structure includes a belt conveyor motor, a belt conveyor roller, and a belt conveyor gear; the belt conveyor motor is fixed to the side wall of the transfer conveyor track, the output end of the belt conveyor motor is fixed to one end of the belt conveyor roller, and the other end of the belt conveyor roller passes through the preset position of the transfer conveyor track; the belt conveyor gear is sleeved on the outer surface of the belt conveyor roller, and the belt conveyor gear drives the belt to move.
[0035] Receiving mechanism 3: Temporarily stores the assembled material strips as an intermediate step, and finally assembles the temporarily stored material strips into a complete material tray with a reasonable head-to-tail order.
[0036] Material splicing and assembly method: The feeding mechanism transmits the tape to the transmission track 22 in the receiving mechanism (the feeding mechanism has been patented and published, and will not be described here). The braiding head of the first reel of the same specification (such as unused braiding reel, bulk leftover material, skipped material, etc.) is transferred to the transfer receiving device 20 via the transfer track 22. The transfer receiving device 20 then transfers the braiding head to the transfer plate in the receiving mechanism 2. When the tail of the first tray reaches the splicing device, the head of the second tray of the same specification also arrives at the same time, and the tail and head of the tray need to be spliced. Simultaneously, during the transmission process, the hot melt adhesive film is detached from the film tape and then applied above the splicing area. When the braided tape at the splice passes the testing device, the testing device measures the resistance at the splice. After resistance testing, the braided tape is heated at the splicing points using a heating device, making the splicing points more secure. The transfer receiving device continues to transfer the heated tape to the transfer tray; When all the tapes of the same specification have been spliced and transferred to the transition tape, it means that the tapes stored on the transition tape have been combined. If the tapes on the transition tape have reached the set number of rolls, but the tapes of the same specification have not yet been spliced, then the shearing device is needed to cut the tapes. The second transition tape, the third transition tape, and so on, will be used until all the tapes of the same specification have been spliced. Finally, the multiple transition tapes are put into the feeding mechanism for splicing again and transferred to the receiving mechanism to the combining tape (a tape larger than the transition tapes).
[0037] It should be noted that the above-mentioned technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this invention specification; and, for those skilled in the art, improvements or modifications can be made based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
