Description

Technical Field

[0001] The present invention relates to the technical field of chip resistor manufacturing, and particularly relates to an automatic assembly and taping tin dipping device for chip resistors. Background Art

[0002] Chip components (SMC and SMD) are new types of tiny components without leads or short leads, and are widely used in contemporary electronic products. They are suitable for installation on printed circuit boards without through holes and are special components for SMT. SMT is the abbreviation of surface mount technology. Compared with ordinary components, chip components can be directly installed on the printed circuit board, and all solder joints are on one plane.

[0003] Chip components not only have different installation methods on the circuit board, but also have completely different manufacturing processes from ordinary components. For example, a chip resistor generally consists of the following materials: a substrate (ceramic substrate), resistor paste (R paste), back conduction material, front conduction material, and side conduction material (Ag paste), primary protection glass G1, secondary protection glass G2, and Mark marking material. A chip resistor sheet is formed through the above materials; usually, chip components are directly installed on the printed circuit board in a surface mount manner and cannot be installed on a perforated printed circuit board; or some high-power chip components are directly installed on the printed circuit board, which is not conducive to achieving mutual isolation between components and between components and the circuit, and is prone to mutual interference. Therefore, it is necessary to develop some chip components with the characteristics of chip components but that can be installed vertically, such as chip resistors with terminals. The process of a chip resistor with terminals is as follows: First, print electrodes, perform primary sintering, print resistor lines, perform secondary sintering, and print a protective glass film on a pre-scored ceramic substrate in sequence, and then split the sheet to obtain a resistor sheet; then shape the terminals, combine the terminals with the resistor sheet manufactured by the chip component process, and snap the resistor sheet into the open end of the above-shaped terminals to form an assembly, so that the horizontally extending parts on both sides of the terminals are attached to the upper and lower surfaces of the resistor sheet, and weld the terminals and the resistor sheet to weld the terminals to the upper and lower surfaces of the resistor sheet to form a bonded body; then perform processes such as insulation encapsulation, curing the insulating layer, plastic shell molding, electrical testing, marking, and trimming the leads to obtain qualified surface mount resistor products.

[0004] During production and manufacturing, the terminals can be automatically mass-produced by stamping, blanking, etc., and the resistor sheets have also achieved automatic printing production and splitting. Then, the terminals and the electrodes on the resistor sheets are assembled and welded together. Currently, usually, the resistor sheets are clamped manually on a specific fixture, the terminals are inserted and assembled at the electrode positions of the resistor sheets, and then a soldering machine is used to solder the electrode positions; since the soldering machine uses a soldering gun for spot welding, it is easy to have poor welding and slow spot welding operations. Therefore, the current quality of the assembly and welding of terminals and resistor sheets is poor and the efficiency is not high. Summary of the Invention

[0099] Optionally, a waste discharging hole 14101 communicating with the punching kit 146 is provided on the punching support 141.

[0100] As Figures 15 - 17 shown, a tape synchronous driving mechanism 100 is provided in the main frame 11. The tape synchronous driving mechanism 100 includes a driving motor 1010, a driving main shaft 101, and a rotation induction component 1012. The driving main shaft 101 drives the active tape pulling mechanism 150 through a tape pulling transmission group 103. A tape sticking cam 104, a punching cam 106, and a tape twisting-out cam 108 are provided on the driving main shaft 101. The tape sticking mechanism 130, the tape punching mechanism 140, and the synchronous tape pulling mechanism 180 are synchronously driven as the driving main shaft 101 rotates.

[0101] Specifically, the tape synchronization driving mechanism 100 includes a driving main shaft 101 installed under the table board 12 through a plurality of main shaft seats 102. The driving motor 1010 is connected to the driving main shaft 101 through a main shaft transmission group 1011.

The punching cam 106 of the driving main shaft 101 is connected to and drives the punching connecting rod 1413 of the tape punching mechanism 140 through a punching rocker arm 107. The tape pulling transmission group 103 of the driving main shaft 101 is connected to the tape pulling divider 152 of the active tape pulling mechanism 150. The tape twisting cam 108 of the driving main shaft 101 is connected to and drives the tape twisting swing arm connecting rod 1814 of the synchronous tape pulling mechanism 180 through a tape twisting rocker arm 109.

[0102] As Figures 4 - 7 shown, the feeding and granule separating mechanism 20 includes a feeding support 21, a conveying seat plate 22 arranged on the feeding support 21, and a feeding motor 27. A conveyor belt assembly 26 is arranged on the conveying seat plate 22. The feeding motor 27 is connected to and drives the conveyor belt assembly 26 through a feeding transmission group 28. Along the conveying direction of the conveyor belt assembly 26, a granule separating connection seat 29 is arranged at the end of the conveying seat plate 22, and a granule separating swing block 210 is installed in the granule separating connection seat 29 through a swing shaft 212. A swing seat plate 211 is connected below the granule separating swing block 210, and a granule separating movable block 213 is arranged on the swing seat plate 211. A limiting and pressing groove 291 is arranged on the granule separating connection seat 29, a granule separating working position groove 2101 communicated with and corresponding to the limiting and pressing groove 291 is arranged on the granule separating swing block 210, an active pressing block 214 is arranged on the granule separating movable block 213 corresponding to the granule separating working position groove 2101, and a granule separating return spring (not shown) is arranged between the granule separating movable block 213 and the granule separating connection seat 29. The active pressing block 214 is combined with or separated from the granule separating working position groove 2101 by a push block cylinder 215. The ceramic substrate 400 enters the limiting and pressing groove 291 from the conveyor belt assembly 26 and reaches the granule separating working position groove 2101. The ceramic substrate 400 is fixed in the limiting and pressing groove 291 by a granule separating pressing rocker arm 222. The swing seat plate 211 drives the granule separating swing block 210 to swing downward by hitting with a swing cylinder 217, and the ceramic substrate 400 cracks along the scratch part to form a resistor chip 201.

[0103] Optionally, along the conveying direction of the conveyor belt assembly 26, a chute support plate 228 is connected and provided at the front end of the conveying seat plate 22. A push block guide groove 2281 is provided in the chute support plate 228 corresponding to the conveyor belt assembly 26. A push piece 231 is arranged in the push block guide groove 2281. A base sheet chute 227 is provided above the push block guide groove 2281. The ceramic base sheets 400 are stacked and placed in the base sheet chute 227. A push piece rodless cylinder 229 is provided below the chute support plate 228 through a push piece mounting plate 232. The push piece rodless cylinder 229 drives the push piece 231 through a push piece connecting block 230 to push the ceramic base sheets 400 falling into the push block guide groove 2281 onto the conveyor belt assembly 26.

[0104] Optionally, a push piece protective cover 233 covering the push piece 231 is further provided at the front side of the base sheet chute 227.

[0105] Optionally, conveying limit baffles 25 are arranged on both sides of the conveyor belt assembly 26 along the conveying seat plate 22. A loading inductor 23 and a loading pressure roller 24 are arranged on the conveying limit baffles 25.

[0106] During use, as Figure 4 、 5 shown, the ceramic base sheets 400 pre-printed with a resistance film, a protective film, and electrodes are processed with a scratch portion according to the resistor sheet specifications. The ceramic base sheets 400 enter the limit pressing groove 291 of the degranulation connection seat 29 through the conveyor belt assembly 26. The front end of the ceramic base sheets 400 reaches the degranulation station groove 2101 on the degranulation swing block 210. The ceramic base sheets 400 are pressed tightly in the limit pressing groove 291. As the degranulation swing block 210 swings downward, the ceramic base sheets 400 are split along the scratch portion to form individual resistor sheets, similar to the action of breaking a thin sheet. The action amplitude is small and the structure is compact.

[0107] Specifically, the limit pressing groove 291 is provided on the upper side of the degranulation connection seat 29. Degranulation limit blocks 218 are respectively arranged on both sides of the limit pressing groove 291. A swing mounting station groove 292 is provided below the limit pressing groove 291. The degranulation swing block 210 is installed in the swing mounting station groove 292 through the swing shaft 212.

[0108] Specifically, along the conveying direction of the ceramic base sheets 400, one side of the degranulation station groove 2101 of the degranulation swing block 210 corresponds to the limit pressing groove 291, and a degranulation stop block 2102 is arranged on the other side. A chip removal groove opening 2105 is formed between the degranulation stop blocks 2102. The chip removal groove opening 2105 is located at the front end of the ceramic base sheets 400. As the conveying action progresses, the chips generated by degranulation fall from the chip removal groove opening 2105 below the mechanism.

[0109] Optionally, swing relief blocks 2104 are respectively provided at two ends of the granule removal swing block 210 perpendicular to the conveying direction of the ceramic substrate 400. The swing relief blocks 2104 are used to avoid interference with the granule removal connection base 29 when the granule removal swing block 210 swings downward.

[0110] As Figure 4 , 7 shown, an active mounting groove 2103 is provided between the granule removal swing block 210 and the swing seat plate 211. The spring accommodation active part 2131 of the granule removal active block 213 cooperates with the active mounting groove 2103. A granule removal return spring station 216 is provided in the spring accommodation active part 2131 for mounting the granule removal return spring (not shown).

[0111] As Figure 4 , 5 shown, a push block cylinder 215 is provided at the rear end of the swing seat plate 211 through a cylinder mounting block. The push block cylinder 215 extends to push the granule removal active block 213 to combine with the granule removal swing block 210. After the push block cylinder 215 contracts, the granule removal return spring separates the granule removal active block 213 from the granule removal swing block 210.

[0112] Specifically, a granule removal positioning table part 2132 is provided on the granule removal active block 213 corresponding to the granule removal station groove 2101. The active pressing block 214 is arranged above the granule removal positioning table part 2132. When the granule removal active block 213 combines with the granule removal swing block 210, the active pressing block 214 covers the front end of the scratched part of the ceramic substrate 400 and restricts it in the granule removal station groove 2101.

[0113] Optionally, granule removal in-place sensors 220 are respectively provided on the granule removal positioning table part 2132 corresponding to the granule removal station groove 2101. The granule removal in-place sensors 220 are proximity switches or sensing optical fibers.

[0114] As Figures 4 - 7 shown, along the conveying direction of the ceramic substrate 400, there is an extension between the granule removal station groove 2101 and the side of the granule removal stop block 2102. When the granule removal active block 213 combines with the granule removal swing block 210, the active pressing block 214 covers the front end of the first scratched part of the ceramic substrate 400 and restricts it in the granule removal station groove 2101. A gap is formed between the front end of the ceramic substrate 400 and the granule removal stop block 2102.

[0115] As Figure 4 , 5As shown, the swing cylinder 217 is fixed to the lower side of the grain separation connection seat 29 through a cylinder mounting seat. A swing acting arm 2111 is extended and provided on the lower side of the swing seat plate 211. The swing cylinder 217 strikes the swing acting arm 2111, driving the grain separation swing block 210 to swing, so that the grain separation working slot 2101 of the grain separation swing block 210 swings downward to separate from the limit pressing slot 291 of the grain separation connection seat 29 and causes the ceramic substrate 400 to crack along the scratch part at the grain separation position.

[0116] During use, the swing cylinder 217 strikes the swing acting arm 2111 to drive the grain separation swing block 210 to swing, and at the same time squeezes the grain separation return spring. After the swing cylinder 217 contracts, the grain separation return spring causes the grain separation working slot 2101 of the grain separation swing block 210 to communicate and combine with the limit pressing slot 291 of the grain separation connection seat 29 again.

[0117] Optionally, a swing adjusting screw 219 is provided in the swing mounting working slot 292 of the grain separation connection seat 29 corresponding to the grain separation swing block 210 or the swing seat plate 211 for adjusting the swing amplitude.

[0118] As Figures 4 - 7 shown, one end of the grain separation pressing swing arm 222 is hinged to the swing arm mounting block 223. The swing arm mounting block 223 is fixed to the pressing support seat 221. A pressing cylinder 224 is provided corresponding to the upper side of the grain separation pressing swing arm 222. The pressing cylinder 224 is fixed to the pressing support seat 221 through a pressing cylinder mounting block 225. A pressing return spring working position 226 is provided between the pressing cylinder mounting block 225 and the grain separation pressing swing arm 222 for installing a pressing return spring (not shown).

[0119] Initially, under the action of the pressing return spring, the grain separation pressing swing arm 222 is away from the limit pressing slot 291 of the grain separation connection seat 29. During grain separation, the pressing cylinder 224 drives the grain separation pressing swing arm 222 to swing downward and presses and fixes the ceramic substrate 400 in the limit pressing slot 291. The pressing support seat 221 can be fixed to the table board, the grain separation connection seat or the end of the conveying seat plate.

[0120] As Figure 8 、 9 shown, the rotary sheet feeding mechanism 30 includes a sleeve seat 31, a sheet feeding rotating shaft 32 arranged in the sleeve seat 31. A material taking cylinder 34 is provided at the upper end of the sheet feeding rotating shaft 32. A material taking suction nozzle 35 is provided at the working end of the material taking cylinder 34. The lower end of the sheet feeding rotating shaft 32 is connected to a rotary cylinder 37 through a rotary connecting block 36; a rotary limit ring 33 is provided at the upper end of the sleeve seat 31. A rotary limit stop block 331 is provided on the rotary limit ring 33, so that the material taking suction nozzle 35 moves between the grain separation working slot and the assembly working position.

[0121] Optionally, a rotary cylinder plate 38 is mounted on the rotary cylinder 37, and a rotary sheet feeding stop lever 39 is arranged on the lower side of the table board 12 corresponding to the rotary cylinder plate 38.

[0122] Initially, the ceramic substrate reaches the grain detachment connecting seat under the conveyance of the conveyor belt assembly. Under the action of the grain detachment return spring, the grain detachment working station groove of the grain detachment swing block communicates and combines with the limit pressing groove of the grain detachment connecting seat. The push block cylinder is in a contracted state. Under the action of the grain detachment return spring, the grain detachment movable block and the grain detachment swing block are in a separated state. The movable pressing block deviates from the grain detachment working station groove, exposing directly above the grain detachment working station groove.

[0123] First, the push block cylinder extends and compresses the grain detachment return spring. The grain detachment movable block combines with the grain detachment swing block, and the movable pressing block covers directly above the grain detachment working station groove.

[0124] Second, when the ceramic substrate reaches inside the grain detachment working station groove, the movable pressing block blocks the front end of the ceramic substrate. The front end of the ceramic substrate is restricted inside the grain detachment working station groove. A gap is formed between the front end of the ceramic substrate and the grain detachment stopper. After sensing that the front end of the ceramic substrate is in place, the pressing cylinder drives the grain detachment pressing swing arm to fix the ceramic substrate in the limit pressing groove, triggering the swinging action arm of the swinging cylinder to strike the swinging seat plate, so that the swinging seat plate, the grain detachment swing block, and the grain detachment movable block swing downward along the swinging shaft simultaneously. The ceramic substrate splits along the scratch part at the connection position of the grain detachment working station groove and the limit pressing groove, forming a resistor chip.

[0125] Then, under the action of the grain detachment return spring, the grain detachment working station groove of the grain detachment swing block and the limit pressing groove of the grain detachment connecting seat resume communication. The push block cylinder contracts. Under the action of the grain detachment return spring again, the grain detachment movable block and the grain detachment swing block separate. The movable pressing block deviates from the grain detachment working station groove, exposing the resistor chip on the grain detachment working station groove. After the push block cylinder contracts, the rotary cylinder operates to make the material taking suction nozzle reach above the grain detachment working station groove. The material taking cylinder contracts to make the suction nozzle move downward to suck and transfer the resistor chip;

[0126] Finally, after sensing that the resistor chip on the grain detachment working station groove has been transferred, the pressing cylinder resets to perform the next splitting and grain detachment action. Since a gap is formed between the front end of the ceramic substrate and the grain detachment stopper, the split resistor chip will not be clamped tightly in the grain detachment working station groove, and the chip discharging slot is conducive to the falling of debris.

[0127] Such as Figure 1 、 2As shown in FIGS. 10-12, the tape feeding mechanism 50 includes a tape feeding support 51 and a tape feeding adjusting plate 52 provided on the tape feeding support 51.

The terminal punching mechanism 60 is arranged on the belt feeding support 51 of one of the belt feeding mechanisms 50. The terminal punching mechanism 60 includes a punching base plate 61 arranged on the belt feeding support 51. A punching slide 63 and a punching slide rod 64 are arranged on the punching base plate 61. The punching slide rod 64 is driven by a punching cylinder 62 to move vertically in the punching slide 63.

The lower end of the punching upper die 67 corresponds to the punching notch 681 of the pressure material ejecting block 68. The punching notches 681 respectively correspond to the punching stations.

[0134] As Figure 2 , 14 shown, the assembly positioning mechanism 80 is arranged on the front side of the punching station, and the terminal transfer mechanism 70 is arranged on the rear side. The terminal transfer mechanism 70 includes a transfer and insertion slide 71 and a transfer and insertion cylinder 73 arranged on the table top plate 12. The transfer and insertion cylinder 73 drives a transfer and insertion slider 72 to reciprocate in the transfer and insertion slide 71. A terminal clamping slide 75 is arranged on the transfer and insertion slider 72 through a transfer and insertion support 74. A terminal clamping gear 79 and a group of clamping rack slide rods 78 are arranged in the terminal clamping slide 75. The upper ends of the clamping rack slide rods 78 are respectively provided with a transfer and insertion lower clamp 710 and a transfer and insertion upper clamp 711. One of the clamping rack slide rods 78 is driven by a terminal clamping cylinder 76. The transfer and insertion lower clamp 710 and the transfer and insertion upper clamp 711 clamp the middle positions of the terminals on both sides at the punching stations in the vertical direction. After two terminals are cut off from the terminal strip 500, they are inserted into the resistor chip electrode positions at the assembly station through the transfer and insertion slider 72.

[0135] Optionally, an insertion vertical adjustment screw 77 is arranged on the transfer and insertion slide 71 for adjusting the opening and closing center of the transfer and insertion lower clamp 710 and the transfer and insertion upper clamp 711 and the center insertion position of the resistor chip.

[0136] Optionally, V-shaped clamping grooves 7101 are provided on both sides of the transfer and insertion lower clamp 710 for positioning the clamping positions of the terminals; an insertion clamp movable block 712 is provided on the transfer and insertion upper clamp 711, and the insertion clamp movable block 712 rotates in the horizontal direction.
