Description

A fully automatic screw fastening machine for copper parts of a slanted five-hole socket. Technical Field

[0001] This invention belongs to the field of copper socket processing technology, and specifically relates to a fully automatic screw fastening machine for copper sockets with slanted five holes. Background Technology

[0002] A socket, also known as a power outlet or switch socket, is a receptacle for inserting one or more electrical wires. This allows for easy connection to other circuits. The connection and disconnection of the circuit is achieved through the connection and disconnection of the wires and copper components. With the widespread use of sockets, competition in the socket market has intensified. Consumers are increasingly dissatisfied with traditional five-hole sockets; angled five-hole sockets, which significantly reduce interference between two-prong and three-prong plugs, have become popular. Meanwhile, fully automatic screw fastening machines, also known as fully automatic screw fastening machines, automatic screw feeders, automatic screw fastening systems, etc., are machines used to replace traditional manual screw tightening.

[0003] Currently, Chinese patent publication number CN214797886U, published on November 19, 2021, discloses a split-type angled five-hole socket, including a back seat, a panel, and an angled five-hole socket copper sheet structure mounted on the back seat. The back seat includes a support plate and a back cover, which are snap-fitted together. The front of the support plate is connected to the panel, and the back of the support plate has a socket mounting position. The back of the support plate has several left-side male buckles, several right-side male buckles, and several support plate female buckles. The back cover has several left-side female buckles that correspond to and are locked with the left-side male buckles, several right-side female buckles that correspond to and are locked with the right-side male buckles, and several back cover male buckles that correspond to and are locked with the support plate female buckles. The angled five-hole socket copper sheet structure includes angled N-pole copper sheets, angled L-pole copper sheets, and E-pole copper sheets.

[0004] When manufacturers mass-produce copper components for sockets, they need to use fully automatic screw-fastening machines to assemble L-shaped copper sheets, terminals, and bolts, and then sell the assembled copper components in bulk.

[0005] Meanwhile, Chinese patent publication number CN205629909U, published on October 12, 2016, discloses an automatic screw fastening machine for copper sheet terminals, including a machine base, a terminal feeding vibratory feeder, a screw feeding vibratory feeder, a station rotary table, and a screw fastening mechanism. The station rotary table is set on the machine base, and multiple evenly spaced mold seats are set on the circumferential edge of the station rotary table. The mold seats are provided with terminal fixing grooves. The screw fastening mechanism includes a base slidably set on the machine base. The base is driven by a first cylinder fixed to the machine base and can slide back and forth on the machine base. A mounting frame is fixed on the base. A linear module is set on the mounting frame along the left and right direction of the machine base. A second cylinder is fixed on the slider of the linear module. The second cylinder drives an electric screwdriver to move up and down. The screw feeding vibratory feeder is set on the machine base adjacent to the screw fastening mechanism.

[0006] The vibratory feeder can be used to feed materials one by one to the rotating turntable at the workstation, which makes it convenient to assemble L-shaped copper sheets, terminals and bolts on the rotating turntable at the workstation. However, when the amount of material in the vibratory feeder is limited, the operator needs to frequently observe the plastic of the material in the vibratory feeder and add material when the material in the vibratory feeder is low. This makes adding material to the vibratory feeder quite time-consuming and laborious. Summary of the Invention

[0007] The purpose of this invention is to provide a fully automatic screw fastening machine for copper parts of a slanted five-hole socket, which can promptly feed materials into the vibratory feeder.

[0008] The above-mentioned technical objective of this invention is achieved through the following technical solution: a fully automatic screw-locking machine for copper parts of a slanted five-hole socket, comprising a machine body, a turntable located at the center of the machine body, multiple assembly seats arranged on the turntable, a vibratory feeder arranged on the outside of the machine body, and an assembly mechanical manual station arranged on the machine body for assembling materials transmitted from the vibratory feeder into the assembly seats. The assembly mechanical manual station includes a first station for threading bolts onto terminals, a second station for inserting terminals with bolts into copper plates, a third station for further tightening the bolts on the terminals after insertion so that the bolts abut against the copper plates, and a fourth station for removing the assembled workpieces from the assembly seats. It also includes a support frame disposed on the lower side of the vibratory feeder, a support platform disposed on the support frame, a first bracket disposed on the upper side of the support platform, baffles disposed on both sides of the first bracket, an active roller rotatably connected to the end of the two baffles away from the vibratory feeder, a driven roller rotatably connected to the end of the two baffles near the vibratory feeder, a transmission belt disposed between the active roller and the driven roller, a servo motor with an output shaft connected to the active roller disposed on the baffles, a material bin disposed above the transmission belt disposed on the upper side of the two baffles near the active roller, and a discharge pipe extending vertically downward with a discharge gap between the lower end and the transmission belt disposed at the lower end of the material bin.

[0009] By adopting the above technical solution, materials are stored in the material silo. When the material in the vibratory feeder is insufficient, the servo motor is started. The servo motor drives the transmission belt through the active roller and the driven roller. Since the discharge pipe extends vertically downward and there is a discharge gap between the lower end and the transmission belt, the material in the discharge gap can be transported out by the transmission belt. After the material falls from the transmission belt, it falls into the vibratory feeder. At the same time, the space in the discharge gap can be filled by the material in the discharge pipe. Finally, the material in the vibratory feeder can be added in a timely manner.

[0010] A further provision of the present invention is that: a connecting arm extending above the vibratory disk is provided at one end of the baffle near the vibratory disk, a distance sensor for detecting the condition of the bottom wall of the vibratory disk is provided at one end of the connecting arm away from the first support, and a controller electrically connected to the distance sensor and used to control the servo motor is provided on the servo motor.

[0011] By adopting the above technical solution, the distance sensor can detect the distance between itself and the material at the bottom wall of the vibratory plate. When the distance sensor detects that the distance between itself and the material at the bottom wall of the vibratory plate is equal to the distance between itself and the bottom wall of the vibratory plate, it means that the material at the bottom wall of the vibratory plate has been consumed and needs to be added. Then the distance sensor can transmit the signal to the controller, which can then control the servo motor to start. The servo motor can then drive the conveyor belt through the active roller and the driven roller. Since the discharge pipe extends vertically downward and there is a discharge gap between its lower end and the conveyor belt, the material in the discharge gap can be transported out by the conveyor belt. After the material falls from the conveyor belt, it falls into the vibratory plate, and finally the material in the vibratory plate can be added in a timely manner.

[0012] A further feature of the present invention is that the orthographic projection of the distance sensor on the bottom wall of the vibratory feeder is located near the bottom periphery of the vibratory feeder, and a guide plate is provided on the inner wall of the baffle located near the distance sensor.

[0013] By adopting the above technical solution, the orthographic projection of the distance sensor on the bottom wall of the vibratory feeder is located near the bottom periphery of the vibratory feeder. A guide plate is provided on the inner wall of the baffle located near the distance sensor. The guide plate can guide the material conveyed by the conveyor belt, so that the falling material avoids the position of the distance sensor, and ultimately avoids the situation where the falling material damages the distance sensor.

[0014] A further setting of the present invention is as follows: A connecting shaft is provided on the first bracket. A shaft sleeve sleeved on the connecting shaft is provided between the lower sides of the two baffles. A fixed arm extending towards the material bin is provided on the baffle. A shaft hole is opened at the upper end of the fixed arm. A rotating shaft passing through the shaft hole is provided on the side wall of the material bin. A driving member for driving the baffle to swing up and down around the connecting shaft is provided on the first bracket.

[0015] By adopting the above technical solution, when the copper parts of the inclined five-hole socket are assembled, the remaining materials in the material bin need to be released. At this time, the driving member is used to drive the baffle to swing downward around the connecting shaft. The material bin is rotatably connected to the fixed arm by the rotating shaft passing through the shaft hole on the fixed arm. As the baffle swings downward, the material bin can be inclined relative to the conveyor belt, and then the remaining materials in the material bin can slide out along the conveyor belt, thus completing the release of the remaining materials in the material bin.

[0016] A further setting of the present invention is as follows: The driving member includes a connecting rod provided at one end of the baffle close to the driving roller, an arc-shaped rack provided at the end of the connecting rod far from the baffle and with its center of the circle on the central axis of the connecting shaft, a stepping motor provided on the first bracket, and a driving gear provided on the output shaft of the stepping motor and meshing with the arc-shaped rack.

[0017] By adopting the above technical solution, the stepping motor is used to drive the driving gear to rotate. Since the driving gear meshes with the arc-shaped rack, the driving gear can drive the arc-shaped rack to rotate around the connecting shaft, and finally drive the baffle to swing up and down around the connecting shaft.

[0018] A further setting of the present invention is as follows: A connecting pipe with a rectangular cross-section is integrally provided at the lower end of the discharge pipe. Guide plates are provided on both sides of the lower end of the connecting pipe. A blocking block for blocking the lower end surface of the connecting pipe is provided at the lower end of the connecting pipe. A clamping groove with a "convex" cross-section for the lower end of the connecting pipe and the guide plates on both sides to be embedded is opened on the blocking block; when the material bin is above the conveyor belt, the lower surface of the blocking block abuts against the upper surface of the conveyor belt; A guiding member for ensuring that the material bin is always in a vertical position when the material bin swings up and down is also provided on the support platform.

[0019] By adopting the above technical solution, when materials need to be added to the material bin, the stepping motor is used to drive the driving gear to rotate to make the baffle swing downward around the connecting shaft, and at the same time, the guiding member is used to ensure that the material bin is always in a vertical position. When the baffle rotates downward to the vertical position, the material bin is at a low position, and at this time, it is convenient for the operator to put the materials into the material bin, without having to carry the materials to the high-position material bin for material addition, which is beneficial to the convenient feeding of the operator;

[0020] When adding materials to the material hopper, the slots of the sealing block allow the lower end of the connecting pipe and the guide plates on both sides to be inserted. At this time, the sealing block can seal the lower end of the connecting pipe, thereby preventing the added materials from leaking from the connecting pipe. Subsequently, the stepper motor drives the drive gear to rotate in the opposite direction, causing the baffle to swing upward around the connecting axis. At the same time, the guide component ensures that the material hopper is always in a vertical position, preventing the material hopper from deflecting when moving upward and causing the materials to pour out from the upper end of the material hopper.

[0021] Simultaneously, as the baffle swings upward around the connecting axis, the conveyor belt gradually presses against the lower surface of the sealing block. When the material bin is above the conveyor belt, the lower surface of the sealing block can completely contact the upper surface of the conveyor belt. When it is necessary to convey material into the vibratory feeder, with the start of the servo motor, the conveyor belt will drive and push the sealing block away from the connecting pipe. Then the connecting pipe and guide plate can be disengaged from the slot. Finally, the sealing block and the connecting pipe can be automatically separated during the conveyor belt's transmission process, so as to cancel the sealing block's blockage of the lower end of the connecting pipe.

[0022] A further configuration of the present invention is that the end of the sealing block near the vibratory feeder has a closed slot, and the end of the sealing block away from the vibratory feeder has an open slot.

[0023] By adopting the above technical solution, the end of the slot of the sealing block near the vibratory feeder is closed, while the end of the slot of the sealing block away from the vibratory feeder is open. This facilitates the stable sealing of the lower end of the connecting pipe by the sealing block, preventing the sealing block from automatically falling off the lower end of the connecting pipe as the material hopper moves upward.

[0024] A further embodiment of the present invention includes: the guide member comprising two connecting ears disposed on the upper side of the material bin, connecting holes formed on the connecting ears, a guide shaft extending horizontally through the connecting holes, a second bracket disposed on the support platform, a long strip plate disposed at the center of the second bracket and extending vertically, mounting arms disposed on both sides of the long strip plate and connected to the second bracket, a long strip hole formed on the long strip plate for the guide shaft to pass through, and a limiting plate disposed on the guide shaft and located on both sides of the long strip plate.

[0025] By adopting the above technical solution, the guide shaft passes through the long hole in the long plate, allowing it to move up and down vertically. Simultaneously, the guide shaft has limiting plates located on both sides of the long plate, which position the guide shaft, ensuring it remains horizontal during vertical movement. Furthermore, by passing the guide shaft through the connecting hole on the connecting lug, the guide shaft moves up and down with the material hopper, ensuring the hopper remains vertical throughout this movement.

[0026] A further feature of the present invention is that: a positioning cylinder is provided on the mounting arm, a first positioning hole is provided at the upper end of the long strip for the piston rod of the positioning cylinder to pass through, and a second positioning hole is provided on the guide shaft for the piston rod of the positioning cylinder to be embedded in.

[0027] By adopting the above technical solution, when the material hopper moves up to the upper limit position, the piston rod of the positioning cylinder passes through the first positioning hole and is embedded in the second positioning hole. In this way, the positioning cylinder provides positioning support for the upper limit position of the material hopper after it moves up, reducing the load on the drive gear and ensuring that there is a discharge gap between the lower end of the connecting pipe and the transmission belt.

[0028] A further feature of the present invention is that: a connecting frame is provided at the upper end of the second bracket, and a piston rod end is provided at the center of the connecting frame for extending and retracting downward to abut against the end of the guide shaft of the support cylinder.

[0029] By adopting the above technical solution, since the material silo at the upper limit position contains a large amount of material, the material silo at the upper limit position has a large gravity. At this time, the guide bearing will be subjected to a large gravity. By using the support cylinder to abut against the end of the guide shaft, the guide shaft can be supported, thereby improving the structural stability of the guide shaft.

[0030] The beneficial effects of this invention are as follows: Materials are stored in the material silo, and a distance sensor can detect the distance between the material and the material at the bottom wall of the vibrating plate. When the distance sensor detects that the distance between the material and the bottom wall of the vibrating plate is equal to the distance between the material and the bottom wall of the vibrating plate, it indicates that the material at the bottom wall of the vibrating plate has been consumed and needs to be added. The distance sensor then transmits a signal to the controller, which in turn controls the servo motor to start. The servo motor then drives the transmission belt via the active roller and the driven roller. Since the discharge pipe extends vertically downwards and has a discharge gap between its lower end and the transmission belt, the material in the discharge gap can be transported out by the transmission belt. After falling from the transmission belt, the material falls into the vibrating plate, and the empty space in the discharge gap can be filled by the material in the discharge pipe. Finally, the material in the vibrating plate can be added in a timely manner.

[0031] Once the copper components of the angled five-hole socket are assembled, the remaining material in the material bin needs to be released. At this time, a stepper motor drives the drive gear to rotate. Since the drive gear meshes with the arc-shaped rack, it can drive the arc-shaped rack to rotate around the connecting shaft, which in turn drives the baffle to swing downward around the connecting shaft. The material bin is connected to the fixed arm by a rotating shaft passing through the shaft hole. As the baffle swings downward, the material bin tilts relative to the conveyor belt, and the remaining material in the material bin slides out along the conveyor belt, thus releasing the remaining material in the material bin.

[0032] Meanwhile, when materials need to be added to the material bin, the stepper motor drives the drive gear to rotate, causing the baffle to swing downward around the connecting shaft. When the baffle rotates downward to the vertical position, the material bin is in the lower position, which makes it convenient for operators to put materials into the material bin without having to carry the materials to the upper material bin for material addition, thus facilitating convenient material addition for operators.

[0033] When adding materials into the material hopper, the slots of the sealing block allow the lower end of the connecting pipe and the guide plates on both sides to be inserted. At this time, the sealing block can seal the lower end of the connecting pipe, thereby preventing the added materials from leaking out of the connecting pipe. Subsequently, the stepper motor drives the drive gear to rotate in the opposite direction, causing the baffle to swing upward around the connecting shaft. At the same time, the guide shaft passes through the connecting hole on the connecting ear to ensure that the material hopper always remains in a vertical position during the up and down movement, preventing the material hopper from deflecting when moving upward and causing the materials to pour out from the upper end of the material hopper.

[0034] Simultaneously, as the baffle swings upward around the connecting axis, the conveyor belt gradually presses against the lower surface of the sealing block. When the material bin is above the conveyor belt, the lower surface of the sealing block can completely contact the upper surface of the conveyor belt. When material needs to be conveyed into the vibratory feeder, with the start of the servo motor, the conveyor belt drives the sealing block to move away from the connecting pipe. Subsequently, the connecting pipe and guide plate can be disengaged from the slot. Finally, the sealing block and the connecting pipe can be automatically separated during the conveyor belt's transmission process, so as to cancel the sealing block's blockage of the lower end of the connecting pipe. When the material bin moves to the upper limit position, the piston rod of the positioning cylinder passes through the first positioning hole and embeds into the second positioning hole, thereby positioning the upper limit position of the material bin after it moves upward, ensuring that there is a discharge gap between the lower end of the connecting pipe and the conveyor belt.

[0050] Referring to FIGS. 2, 3, and 5, a connecting pipe 511 with a rectangular cross-section is integrally provided at the lower end of the discharging pipe 51. There is a discharging gap between the lower end of the connecting pipe 511 and the conveyor belt 413. Guide plates 512 are integrally provided on both sides of the lower end of the connecting pipe 511. A blocking block 7 is provided at the lower end of the connecting pipe 511 to block the lower end surface of the connecting pipe 511. A groove 71 with a "convex" cross-section for the lower end of the connecting pipe 511 and the guide plates 512 on both sides to be embedded is formed on the blocking block 7. The end of the groove 71 near the vibrating disk 2 is closed, and the end of the groove 71 far from the vibrating disk 2 is open; when the material bin 5 is located above the conveyor belt 413, the lower surface of the blocking block 7 abuts against the upper surface of the conveyor belt 413; since the conveyor belt 413 is made of a flexible material, when the conveyor belt 413 gradually abuts against the blocking block 7 after rotation, the conveyor belt 413 can adapt to the movement track of the blocking block 7 after undergoing a concave deformation.

[0051] Referring to FIGS. 2, 3, and 6, a guiding member 8 is further provided on the support platform 31 to ensure that the material bin 5 is always in a vertical position when the material bin 5 swings up and down. The guiding member 8 includes connecting ears 81, connecting holes 82, guiding shafts 83, a second bracket 84, a long strip plate 85, mounting arms 86, long strip holes 87, and limiting plates 88. Two connecting ears 81 are provided and integrally arranged on both sides of the upper side of the material bin 5. The connecting holes 82 are formed in the connecting ears 81. The guiding shafts 83 pass through the connecting holes 82 in the two connecting ears 81. The second bracket 84 is fixed to the support platform 31 by bolts. The long strip plate 85 is located at the center of the second bracket 84 and extends in the vertical direction. One end of the mounting arm 86 is welded to the long strip plate 85 and the other end is welded to the second bracket 84. The long strip hole 87 is formed in the long strip plate 85 for the guiding shaft 83 to pass through. The limiting plates 88 are integrally arranged on the guiding shafts 83 and located on both sides of the long strip plate 85. The limiting plates 88 are circular and the outer diameter is larger than the width of the long strip hole 87; a positioning cylinder 861 is fixed to the mounting arm 86 by bolts. A first positioning hole 851 for the piston rod of the positioning cylinder 861 to pass through is formed at the upper end of the long strip plate 85. A second positioning hole 831 for the piston rod of the positioning cylinder 861 to be embedded is formed in the guiding shaft 83; a connecting frame 841 in a "U" shape is welded to the upper end of the second bracket 84. A support cylinder 842 is fixed to the center of the connecting frame 841 by bolts. The end of the piston rod of the support cylinder 842 is used to extend and retract downward to abut against the end of the guiding shaft 83.

[0052] Principle: Material is stored in the material bin 5. The distance sensor 416 can detect the distance between the material and the bottom wall of the vibrating plate 2. When the distance sensor 416 detects that the distance between the material and the bottom wall of the vibrating plate 2 is equal to the distance between the material and the bottom wall of the vibrating plate 2, it means that the material at the bottom wall of the vibrating plate 2 has been consumed and needs to be added. Then the distance sensor 416 can transmit the signal to the controller 417, and the controller 417 can control the servo motor 414 to start. Then the servo motor 414 can drive the transmission belt 413 through the active roller 411 and the driven roller 412. Since the discharge pipe 51 extends vertically downward and there is a discharge gap between the lower end and the transmission belt 413, the material in the discharge gap can be transported out by the transmission belt 413. After the material falls from the transmission belt 413, it falls into the vibrating plate 2. At the same time, the space in the discharge gap can be filled by the material in the discharge pipe 51. Finally, the material in the vibrating plate 2 can be added in time.

[0053] After the copper parts of the slanted five-hole socket are assembled, the remaining material in the material bin 5 needs to be released. At this time, the piston rod of the positioning cylinder 861 is first moved out of the second positioning hole 831. Then, the stepper motor 63 drives the drive gear 64 to rotate. Since the drive gear 64 is meshed on the arc rack 62, the drive gear 64 can drive the arc rack 62 to rotate around the connecting shaft 42. Finally, it can drive the baffle 41 to swing downward around the connecting shaft 42. The material bin 5 is rotatably connected to the fixed arm 420 by the shaft 52 passing through the shaft hole 4201 on the fixed arm 420. As the baffle 41 swings downward, the material bin 5 can tilt relative to the conveyor belt 413. Then, the remaining material in the material bin 5 can slide out along the conveyor belt 413, thereby completing the release of the remaining material in the material bin 5.

[0054] Meanwhile, when materials need to be added to the material bin 5, the piston rod of the positioning cylinder 861 is first moved out of the second positioning hole 831. The stepper motor 63 drives the drive gear 64 to rotate, causing the baffle 41 to swing downward around the connecting shaft 42. When the baffle 41 rotates downward to the vertical position, the material bin 5 will be in the low position. At this time, it is convenient for the operator to put the materials into the material bin 5 without having to carry the materials to the high material bin 5 for material addition, which is conducive to the operator's convenient material addition.

[0055] When materials are added to the material bin 5, the slot 71 of the sealing block 7 allows the lower end of the connecting pipe 511 and the guide plates 512 on both sides to be inserted. At this time, the sealing block 7 can seal the lower end of the connecting pipe 511, thereby preventing the added materials from leaking from the connecting pipe 511. Subsequently, the stepper motor 63 drives the drive gear 64 to rotate in the opposite direction, causing the baffle 41 to swing upward around the connecting shaft 42. At the same time, the guide shaft 83 passes through the connecting hole 82 on the connecting ear 81 to ensure that the material bin 5 always remains in a vertical position during the up and down movement, preventing the material bin 5 from deflecting when moving upward and causing the materials to pour out from the upper end of the material bin 5.

[0056] Simultaneously, as the baffle 41 swings upward around the connecting shaft 42, the conveyor belt 413 gradually presses against the lower surface of the sealing block 7. When the material bin 5 is above the conveyor belt 413, the lower surface of the sealing block 7 can completely contact the upper surface of the conveyor belt 413. When it is necessary to convey material into the vibratory feeder 2, with the start of the servo motor 414, the conveyor belt 413 will drive and push the sealing block 7 to move away from the connecting pipe 511. Then, the connecting pipe 511 and the guide plate 512 can exit from the slot 71. The sealing block 7 and the connecting pipe 511 can be automatically separated during the transmission process of the conveyor belt 413, so as to remove the sealing block 7 from the lower end of the connecting pipe 511; when the material bin 5 moves up to the upper limit position, the piston rod of the positioning cylinder 861 passes through the first positioning hole 851 and is embedded in the second positioning hole 831, thereby positioning the upper limit position of the material bin 5 after it moves up through the positioning cylinder 861, ensuring that there is a discharge gap between the lower end of the connecting pipe 511 and the conveyor belt 413.
