Description

Technical Field

[0001] The present invention relates to the technical field of assembly equipment, and specifically to an automated fastener assembly equipment. Background Art

[0002] Terminal blocks are applied to facilitate the connection of wires. For example, for two wires, sometimes they need to be connected and sometimes disconnected. In this case, terminal blocks can be used to connect them, and they can be disconnected at any time without having to weld or wind them together, which is convenient and fast to operate. Specifically, in the industry, it is classified into the category of connectors.

[0003] With the increasing level of industrial automation and the increasingly strict and precise requirements for industrial control, the usage of terminal blocks has gradually increased. With the development of the electronics industry, the application scope of terminal blocks is becoming wider and wider, and the types are also increasing.

[0004] As is well known, a terminal block is composed of structures such as metal sheets, metal nails, and a terminal block box. When assembling a terminal block, the existing assembly device uses a motor as the power source, transports the terminal block box with a conveyor belt, and then manually adds metal sheets into the terminal block box to achieve the assembly of the terminal block. This kind of assembly equipment consumes too much manpower, especially when manually pressing the metal nails into the terminal block box, it is very laborious.

[0005] In order to improve work efficiency, relevant patents have been proposed in the prior art. For example, a Chinese patent with the authorization announcement number CN222088484U and the name of an assembly equipment for terminal blocks discloses an assembly equipment for terminal blocks, including a box body. A clamping box is fixedly connected to the bottom of the box body, a clamping device is arranged inside the clamping box, and an adjusting device is arranged above the box body. Advantages of the present invention: The junction box can be more stably fixed and installed, and can be adjusted according to the size of the junction box to make the clamping of the junction box more stable during installation.

[0006] For another example, there is a Chinese patent with the authorization announcement number CN222884069 and the name of an automatic assembly device for wiring terminals. The above patent discloses an automatic assembly device for wiring terminals, which solves the problem of poor use effect of the existing assembly devices. It includes a support table, and a first vibrating plate, a second vibrating plate, an assembly mechanism and a controller are fixedly arranged at the top of the support table. The assembly mechanism is connected to the first vibrating plate and the second vibrating plate, and the first vibrating plate, the second vibrating plate and the assembly mechanism are all electrically connected to the controller. The assembly mechanism is composed of a first feeding frame, a first pushing component, a second feeding frame, a second pushing component and an extrusion docking component. The first feeding frame, the second feeding frame and the extrusion docking component are all fixedly connected to the top of the support table, the first pushing component is fixedly connected to one side of the first feeding frame, and the second pushing component is fixedly connected to one side of the second feeding frame. Through the above automatic assembly device in the patent, automatic assembly of the wiring terminals can be realized, and the assembly efficiency can be improved.

[0007] In the prior art such as the above patent, the assembly needs of fasteners can be met to a certain extent. As is well known, in order to facilitate the later use of fasteners, the metal nail and the terminal box are generally threadedly connected, so threaded holes adapted to the metal nail are provided on the terminal box. An insertion rod is provided at the end of the metal nail, and insertion holes adapted to the insertion rod are provided on the metal sheet. During the assembly process, the insertion rod at the end of the metal nail needs to be inserted into the insertion hole on the metal sheet, and then a pressing component is used to drive the metal sheet to deform so that the metal sheet is connected to the insertion rod to meet the working needs of the subsequent fasteners. During the above operation process, it is necessary to first adjust the metal nail to the same horizontal line as the threaded hole on the terminal box, and then use a motor to drive the metal nail to rotate while driving the motor to slide horizontally through a driving source, so that the metal nail is threadedly connected to the inside of the terminal box and the insertion rod is clamped into the insertion hole on the metal sheet. After that, the terminal box is driven to rotate to the next station, and a pressing component is used to drive the metal sheet to deform, and then a clamping and blanking mechanism is used for blanking.

[0008] During the above operation process, after the metal nail is threadedly connected to the inside of the terminal box, only the driving source can be used to drive the terminal box to rotate to the next station to perform the extrusion operation, which increases the work burden. At the same time, due to the use of multiple driving sources, numerical control technology is also required to accurately match the extrusion mechanism with multiple driving sources. The increase in numerical control technology not only causes an increase in the overall cost of the equipment in the assembly and processing of fasteners, but also increases the overall failure rate of the equipment, which has certain deficiencies.

[0009] Therefore, it can be seen that how to realize the threaded connection of the metal nail to the inside of the terminal box through a driving source on one device and then passively connect the metal nail to the metal sheet is a technical problem that urgently needs to be solved. Summary of the Invention

[0010] The object of the present invention is to provide an automated fastener assembly device to solve the problems raised in the above background technology.

[0011] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automated fastener assembly device, comprising a workbench and a support frame installed on the workbench, and also comprising a plurality of feeding mechanisms, the feeding mechanisms being located on one side of the workbench, a rotating disk being rotatably connected to the workbench, a plurality of fastening parts being installed on the rotating disk, and a terminal box, a metal sheet and a metal nail being sequentially loaded on the rotating disk through the feeding mechanism, a motor being slidably connected to the workbench, and the motor output shaft being clamped with the metal nail; a servo cylinder for driving the motor to slide is arranged on the workbench; a pier pressing part is vertically connected to the support frame, and the pier pressing part and the servo cylinder are transmission-connected via a buffer linkage mechanism; after the servo cylinder drives the motor to install the metal nail into the terminal box, it continues to drive the pier pressing part to connect the metal sheet with the metal nail via the buffer linkage mechanism.

[0012] Furthermore, the buffer linkage mechanism includes a power frame slidably connected to the workbench, and a first rack is fixedly connected to the power frame, and the pier pressing part and the first rack are transmission connected via a gear transmission member; the motor is slidably connected to the workbench via a sliding plate, and a buffer part is arranged between the power frame and the sliding plate.

[0013] Furthermore, the buffer part includes a bearing cylinder fixedly connected to the power frame, and a sliding rod slidably connected to the bearing cylinder is fixedly connected to the sliding plate, and a buffer spring is arranged between the sliding rod and the bearing cylinder.

[0014] Furthermore, the rotating disk and the power frame are connected via a one-way transmission mechanism; the one-way transmission mechanism includes a rotating rod fixedly connected to the rotating disk, the rotating rod is rotatably connected to the workbench, and the workbench is also rotatably connected to a transmission rod, a one-way transmission part is arranged between the transmission rod and the rotating rod; and a gear power part is arranged between the power frame and the transmission rod.

[0015] Furthermore, the one-way transmission part includes a wedge-shaped rod, which is slidably connected to the transmission rod through a sliding groove, and a slot adapted to the wedge-shaped rod is opened on the rotating rod, and an abutment spring is arranged between the wedge-shaped rod and the sliding groove, and the elastic force of the abutment spring drives the wedge-shaped rod to be clamped into the slot.

[0016] Further, a plurality of support parts are slidably connected to the workbench, and each support part is respectively located below the fastening part; the support part includes a plurality of support plates slidably connected to the workbench, the terminal box is located above the support plates, the plurality of support plates are fixedly connected by a connecting plate, and a reset part is further arranged between the connecting plate and the workbench; a guiding and lifting part is further arranged between the support part and the workbench. When the rotating disc rotates, the support part drives the assembled terminal box to move upward through the guiding and lifting part to get out of the restriction of the fastening part.

[0017] Further, the guiding and lifting part includes a guiding rod fixedly connected to the connecting plate, and the guiding rod is slidably connected to the rotating disc; a rotating groove is formed in the workbench, the guiding rod is rotatably connected to the rotating groove, and a stabilizing groove is further formed in the workbench, and the stabilizing groove is communicated with the rotating groove through a guiding groove.

[0018] Further, a positioning frame is further fixedly connected to the support frame, and a blanking part for driving the assembled terminal box to be blanked is slidably connected inside the positioning frame, and the blanking part is in transmission connection with the first rack.

[0019] Further, the blanking part includes a blanking push block slidably connected inside the positioning frame, a threaded rod is rotatably connected to the positioning frame, and the blanking push block is threadedly connected to the threaded rod through a threaded hole; a support rod is rotatably connected to the positioning frame, a power gear is installed on the support rod, the power gear is meshed with the first rack, and the support rod and the threaded rod are in transmission connection through a synchronizing part.

[0020] Further, a positioning part is slidably connected inside the fastening part, and the positioning part includes a positioning block slidably connected to the rotating disc through an adaptation groove, and a positioning spring is arranged between the positioning block and the rotating disc.

[0021] Compared with the prior art, the beneficial effect of the present invention is that: during use, the automatic fastener assembly equipment can load the terminal box, the metal sheet and the metal nail in sequence by rotating the disk in coordination with the loading mechanism, and adjust the metal nail to the same horizontal line as the threaded hole on the terminal box. Then, the motor is driven by the servo cylinder to move horizontally on the workbench so that the motor output shaft is engaged with the metal nail. When the motor is started, the metal nail is installed inside the terminal box as the servo cylinder drives the motor to slide horizontally on the workbench, and then the motor is automatically turned off. During the horizontal sliding stroke of the motor on the workbench driven by the servo cylinder, the pier pressing part is driven to move downward through the buffer linkage. When the metal nail is installed inside the terminal box, the servo cylinder drives the pier pressing part to contact the metal sheet through the buffer linkage mechanism at this moment, and continues to drive the pier pressing part to move downward, and the metal sheet is deformed so that the clamping rod of the metal nail is clamped in the clamping groove on the metal sheet, so that the clamping rod is engaged with the clamping groove, which satisfies the normal use of subsequent fasteners. And when the pressing part contacts the metal sheet, the motor stops sliding due to the action of the buffer linkage mechanism, and no motion interference occurs. At this moment, when the motor stops sliding, the thrust of the servo cylinder is transmitted to the pressing part for extrusion. This is equivalent to partially overlapping or closely connecting the two originally serial processes of "screwing in" and "pressing".

[0022] Originally, it was necessary to first thread the metal nail into the terminal box, and then drive the terminal box to rotate to the next station for extrusion. Now, after the servo cylinder drives the motor to install the metal nail, the pier pressing operation can be completed directly through the buffer linkage mechanism, without waiting for the terminal box to rotate and switch stations, which greatly shortens the time for switching between processes, making the entire assembly process more compact and coherent, and significantly improving production efficiency.

[0023] After the metal nail is screwed into place, the relative position of the metal sheet and the plug rod has been determined during the screwing process, that is, the plug rod has been inserted into the slot. If it is rotated to the next station, it will inevitably introduce a slight positioning error (mechanical clearance, vibration, etc.), which may cause the plug rod and the socket to be misaligned during pier pressing. However, completing all operations at the same position completely eliminates this secondary positioning error, ensures the best alignment of the plug rod and the socket during pier pressing, and improves the consistency and reliability of the connection.

[0024] The existing technical process involves multiple drive sources, which are respectively used to drive the motor, rotate the terminal box, and perform subsequent extrusion operations. The improved design takes the servo cylinder as the core drive, cooperates with the buffer linkage mechanism, integrates some drive functions, reduces the number of required drive sources, and directly reduces the procurement cost of the equipment in the drive system. Since there is no longer a need to complexly adapt the precise cooperation of multiple drive sources through numerical control technology, the corresponding numerical control system and the investment in related components are saved, the overall structure of the equipment is simplified, and the manufacturing difficulty is reduced. This is also beneficial to reducing the initial purchase cost and subsequent maintenance cost of the equipment, and improving the cost performance of the equipment. Brief Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1 - 16The present invention provides a technical solution: an automated fastener assembly device, comprising a workbench 1 and a support frame 3 installed on the workbench 1, and also comprising multiple groups of feeding mechanisms, the feeding mechanisms are located on one side of the workbench 1, a rotating disk 2 is rotatably connected to the workbench 1, multiple groups of fastening parts 5 are installed on the rotating disk 2, and the rotating disk 2 is sequentially loaded with terminal boxes 6, metal sheets 8 and metal nails 7 through the feeding mechanism, a motor 10 is slidably connected to the workbench 1, and the output shaft of the motor 10 is clamped with the metal nail 7; a servo cylinder 11 for driving the motor 10 to slide is arranged on the workbench 1; a pier pressing part 13 is vertically connected to the support frame 3, and the pier pressing part 13 is transmission-connected to the servo cylinder 11 through a buffer linkage mechanism 14; the servo cylinder 11 drives the motor 10 to install the metal nail 7 into the terminal box 6, and then continues to drive the pier pressing part 13 to connect the metal sheet 8 with the metal nail 7 through the buffer linkage mechanism 14.

[0030] Specifically, the automated fastener assembly device includes a workbench 1 and a support frame 3 installed on the workbench 1. At the same time, a controller 4 is provided on the workbench 1 to control the operation of the entire device. Specifically, multiple sets of support members are provided at the bottom of the workbench 1 to improve the stability of the entire assembly device during operation. It also includes multiple sets of feeding mechanisms. The feeding mechanisms are located on one side of the workbench 1 and are used to feed the various components of the fastener. A rotating disk 2 is rotatably connected to the workbench 1, and multiple sets of fastening parts 5 are installed on the rotating disk 2 to restrict the terminal box 6. The terminal box 6, metal sheet 8, and metal nail 7 are sequentially fed onto the rotating disk 2 through the feeding mechanism. Specifically, the number of feeding mechanisms can be three, which are respectively arranged on the periphery of the workbench 1 and are used for feeding the terminal box 6, metal sheet 8, and metal nail 7. Specifically, four working stations are provided on the workbench 1, namely the first station, the second station, the third station, and the fourth station. During this working process, first, use the first feeding mechanism (i.e., at the first station, for feeding the terminal box 6) to feed the terminal box 6 into the interior of the fastening part 5, and the fastening part 5 restricts the terminal box 6; then the rotating disk 2 rotates a certain distance, and the second feeding mechanism feeds the metal sheet 8 into the terminal box 6 (at this moment, operating at the second station, installing the metal sheet 8 into the terminal box 6); then the rotating disk 2 continues to rotate. After rotating a certain distance, use the third feeding mechanism (at this moment, operating at the third station, for installing the metal nail 7 into the terminal box 6) to feed the metal nail 7 to the predetermined position and adjust the metal nail 7 to the same horizontal line as the threaded hole on the terminal box 6 to meet the subsequent assembly requirements of the fastener; after the assembly is completed, a discharge slot 20 is provided on the workbench 1, that is, this discharge slot 20 is the fourth station, which is convenient for discharging the assembled fastener. After that, the rotating disk 2 will rotate inside the workbench 1, from the first station - the second station - the third station - the fourth station, and then back from the fourth station to the first station in a cycle. The feeding mechanism can be composed of a vibrating feeding tray and a robotic arm for feeding. The structures and working principles of the vibrating feeding tray and the robotic arm are all prior arts and will not be elaborated here.

[0031] More specifically, threaded holes are provided on the terminal box 6, and the metal nails 7 are threadedly connected to the terminal box 6 through the threaded holes. At the same time, a clamping rod 71 is fixedly connected to the metal nail 7, and a clamping groove 81 adapted to the metal sheet 8 is provided on the metal sheet 8, wherein the clamping rod 71 is slidably connected to the clamping groove 81. When the metal nail 7 is threadedly connected inside the terminal box 6, the clamping rod 71 at this moment will be installed in the clamping groove 81 on the metal sheet 8. If the metal sheet 8 is deformed, the clamping groove 81 on the metal sheet 8 will also be deformed, and the deformed clamping groove 81 will be clamped with the clamping rod 71. Preferably, the clamping rod 71 is rotatably connected to the clamping groove 81, that is, if it is necessary to adjust the distance between the metal sheet 8 and the terminal box 6 according to the working needs later, at this time, only need to drive the metal nail 7 to rotate, which will drive the metal sheet 8 to slide inside the terminal box 6 to meet the working needs.

[0032] A motor 10 is slidably connected to the workbench 1, and the output shaft of the motor 10 is clamped with the metal nail 7. A clamping portion is provided on the output shaft of the motor 10. Specifically, a "cross" groove is provided at the end of the metal nail 7, and the clamping portion on the output shaft of the motor 10 is clamped and matched with the "cross" groove. When the clamping portion is clamped inside the "cross" groove, when the output shaft of the motor 10 rotates, it will drive the metal nail 7 to rotate through the "cross" groove to achieve the working requirement of installing the metal nail 7 inside the terminal box 6, and the use effect is better.

[0033] The workbench 1 is provided with a servo cylinder 11 for driving the motor 10 to slide, which provides power for the motor 10 to slide, so that the metal nail 7 can be better installed inside the terminal box 6 to meet the work needs. The support frame 3 is vertically connected with a pier pressing part 13, wherein the pier pressing part 13 is the existing technology, preferably made of solid metal material, with a hard texture. After contacting with the metal sheet 8, when the metal sheet 8 continues to be squeezed, the metal sheet 8 will be deformed. Specifically, the pier pressing part 13 is connected to the servo cylinder 11 through a buffer linkage mechanism 14, that is, the movement of the pier pressing part 13 is also driven by the servo cylinder 11, and the effect is better. After the servo cylinder 11 drives the motor 10 to install the metal nail 7 inside the terminal box 6, it continues to drive the pier pressing part 13 through the buffer linkage mechanism 14 to connect the metal sheet 8 with the metal nail 7. Specifically, during use, the terminal box 6, the metal sheet 8 and the metal nail 7 can be loaded in sequence by rotating the disk 2 in coordination with the loading mechanism, and the metal nail 7 is adjusted to be on the same horizontal line as the threaded hole on the terminal box 6. Then, the motor 10 is driven by the servo cylinder 11 to move horizontally on the workbench 1, so that the output shaft of the motor 10 is engaged with the metal nail 7. When the motor 10 is started, the servo cylinder 11 drives the motor 10 to slide horizontally on the workbench 1, and the metal nail 7 is installed inside the terminal box 6, and then the motor 10 is automatically turned off. The servo cylinder 11 drives the motor 10 to move downward through the buffer linkage during the horizontal sliding stroke on the workbench 1. At this moment, when the metal nail 7 is installed inside the terminal box 6, the servo cylinder 11 drives the pier pressing part 13 to contact the metal sheet 8 through the buffer linkage mechanism 14, and continues to drive the pier pressing part 13 to move downward, and the metal sheet 8 is deformed, so that the clamping rod 71 of the metal nail 7 is clamped in the clamping groove 81 on the metal sheet 8, and the clamping rod 71 is engaged with the clamping groove 81, which meets the normal use of the subsequent fasteners. And when the pier pressing part 13 contacts the metal sheet 8, at this moment, due to the action of the buffer linkage mechanism 14, the motor 10 stops sliding and does not cause motion interference. At this moment, when the motor 10 stops sliding, the thrust of the servo cylinder 11 will be transmitted to the pier pressing part 13 for extrusion. This is equivalent to partially overlapping or closely connecting the two originally serial processes of "screwing in" and "pier pressing".

[0034] Originally, it was necessary to first thread the metal nail 7 into the terminal box 6, and then drive the terminal box 6 to rotate to the next station for extrusion. Now, after the servo cylinder 11 drives the motor 10 to install the metal nail 7, the pier pressing operation can be completed directly through the buffer linkage mechanism 14, without waiting for the terminal box 6 to rotate to switch stations, which greatly shortens the time for switching between processes, making the entire assembly process more compact and coherent, and significantly improving production efficiency.

[0035] And after the metal nail 7 is screwed into place, the relative positions of the metal sheet 8 and the insertion rod have been determined during the screwing process, that is, the insertion rod has been inserted into the card slot 81. If it is rotated to the next working station, it will inevitably introduce tiny positioning errors (mechanical clearances, vibrations, etc.), which may cause the misalignment of the insertion rod and the insertion hole during caulking. The new solution completes all operations at the same position, completely eliminating this secondary positioning error, ensuring the best alignment of the insertion rod and the insertion hole during caulking, and improving the consistency and reliability of the connection.

[0036] In the prior art, multiple drive sources are involved, which are respectively used to drive the rotation of the motor 10, the terminal box 6 and subsequent extrusion operations. The improved design takes the servo cylinder 11 as the core drive, and cooperates with the buffer linkage mechanism 14 to integrate some drive functions, reduce the number of required drive sources, and directly reduce the procurement cost of the equipment in the drive system. Since there is no longer a need to complexly adapt the precise cooperation of multiple drive sources through numerical control technology, the corresponding numerical control system and related components are eliminated, the overall structure of the equipment is simplified, and the manufacturing difficulty is reduced. This is also beneficial to reducing the initial purchase cost and subsequent maintenance cost of the equipment, and improving the cost performance of the equipment.

[0037] After the equipment structure is simplified, the number of components is reduced. When maintenance personnel perform daily inspections, fault troubleshooting, and component replacement, the workload is significantly reduced, and problems can be located and solved more quickly, improving the maintenance efficiency of the equipment and ensuring the normal production operation of the equipment.

[0038] In the embodiment provided by the present invention, the buffer linkage mechanism 14 includes a power frame 145 slidably connected to the workbench 1, and a first rack 141 is fixedly connected to the power frame 145, and the pier pressing part 13 is connected to the first rack 141 through a gear transmission member. The servo cylinder 11 is connected to the power frame 145 to drive the power frame 145 to slide horizontally. Specifically, the gear transmission member includes a long gear 142 rotatably connected to the support frame 3, and a mounting plate 131 is fixedly connected to the pier pressing part 13, the mounting plate 131 is slidably connected to the support frame 3, and a plurality of groups of limiting telescopic rods are arranged between the mounting plate 131 and the support frame 3 to improve the stability of the mounting plate 131 when sliding vertically, and to improve the quality of subsequent pier pressing, wherein a second rack 143 is fixedly connected to the mounting plate 131, the second rack 143 is meshed with the long gear 142, and the first rack 141 is also meshed with the long gear 142. When the first rack 141 slides, it will drive the long gear 142 to rotate, and transmit the force to the second rack 143, and drive the mounting plate 131 to move downward through the second rack 143, which is convenient for the later pier pressing operation and meets the work needs. The motor 10 is slidably connected to the workbench 1 through the sliding plate 9. Preferably, a plurality of sets of limiting parts 12 are arranged between the sliding plate 9 and the workbench 1 to improve the stability of the sliding plate 9 when sliding, and the use effect is better. At the same time, the limiting part includes a limiting block fixedly connected to the bottom of the sliding plate 9, and a limiting groove adapted to the limiting block is provided on the workbench 1, and the limiting block is slidably connected to the limiting groove. And the position and length of the limiting groove can be set according to the work needs. A buffer portion 144 is provided between the power frame 145 and the sliding plate 9, and the buffer portion 144 includes a bearing tube 1441 fixedly connected to the power frame 145, and a sliding rod 1443 slidably connected to the bearing tube 1441 is fixedly connected to the sliding plate 9, and a buffer spring 1442 is provided between the sliding rod 1443 and the bearing tube 1441. Specifically, the elastic force of the buffer spring 1442 drives the sliding rod 1443 and the bearing tube 1441 to move away from each other. That is, during use, when the servo cylinder 11 drives the power frame 145 to slide, at this moment, the motor 10 is driven to slide on the workbench 1 through the buffer portion 144 and the sliding plate 9, and the metal nail 7 is installed inside the terminal box 6, and then the motor 10 is automatically turned off. In this process, the servo cylinder 11 continuously drives the power frame 145 to slide. At this moment, the sliding plate 9 stops sliding due to the restriction of the limit part 12. At this moment, when the power frame 145 moves on the workbench 1, it will drive the slide bar 1443 to slide inside the bearing cylinder 1441, thereby squeezing the buffer spring 1442 to offset the force driving the motor 10 to move forward. When the power frame 145 continues to slide, it drives the first rack 141 to slide on the support frame 3. When the first rack 141 slides, it drives the long gear 142 to rotate, and transmits the force to the second rack 143. The second rack 143 drives the mounting plate 131 to move downward, and the metal sheet 8 is pressed to meet the work needs.The servo cylinder 11 moves accurately and quickly, and can drive the motor 10 and operate the subsequent buffer linkage mechanism 14 in a relatively short time, so that the installation of the metal nail 7 and the extrusion connection of the metal sheet 8 are closely coordinated. The output of the equipment per unit time is increased, which helps the company to manufacture more products within the same production cycle and meet market demand.

[0039] In the embodiment provided by the present invention, the rotating disk 2 is connected to the power frame 145 through a one-way transmission mechanism 17, that is, when the servo cylinder 11 is needed to drive the motor 10 to assemble the metal nail 7 and the pier pressing part 13 to perform the pier pressing operation on the metal sheet 8, the rotating disk 2 at this moment stops rotating. When the metal nail 7 is installed inside the terminal box 6 and the metal sheet 8 has completed the pier pressing operation, the servo cylinder 11 will be used to drive the motor 10 and the pier pressing part 13 to reset. At this moment, the rotating disk 2 is driven to rotate by the one-way transmission mechanism 17 during the reset stroke of the motor 10 and the pier pressing part 13 to meet the work needs. The reset action of the servo cylinder 11 after the processing is completed is usually an action that must be performed but does not directly generate processing value. By setting a one-way transmission member, the energy released when the cylinder is reset is effectively "captured" and converted into power to drive the rotating disk 2 to rotate through the one-way transmission mechanism 17, thereby avoiding the waste of this part of energy and achieving better results.

[0040] Specifically, the one-way transmission mechanism 17 includes a rotating rod 171 fixedly connected to the rotating disk 2. The rotating rod 171 is rotatably connected to the workbench 1, and a transmission rod 172 is also rotatably connected to the workbench 1. A one-way transmission part 176 is provided between the transmission rod 172 and the rotating rod 171; a gear power part is provided between the power frame 145 and the transmission rod 172. Specifically, the gear power part includes a transmission gear 173 installed on the transmission rod 172, and a transmission rack 174 is fixedly connected to the power frame 145. The transmission gear 173 meshes with the transmission rack 174. The one-way transmission part 176 includes a wedge-shaped inserting rod 1761. The wedge-shaped inserting rod 1761 is slidably connected to the transmission rod 172 through a chute, and a slot 1762 adapted to the wedge-shaped inserting rod 1761 is provided on the rotating rod 171. A contact spring 1763 is provided between the wedge-shaped inserting rod 1761 and the chute. The elastic force of the contact spring 1763 drives the wedge-shaped inserting rod 1761 to be clamped into the slot 1762. That is, during the use process, when driving the metal nail 7 to be assembled into the terminal box 6 and needing to perform a caulking operation on the metal sheet 8, at this moment, the power frame 145 drives the transmission rack 174 to slide, drives the transmission gear 173 to rotate through the transmission rack 174, drives the transmission rod 172 to rotate. At this moment, when the transmission rod 172 rotates, the wedge-shaped surface on the wedge-shaped inserting rod 1761 abuts against the inclined surface of the slot 1762, and at this moment, the rotating rod 171 cannot be driven to rotate. On the contrary, when the transmission rack 174 slides in the reverse direction, it will drive the transmission rod 172 to rotate through the cooperation of the transmission gear 173. At this moment, the straight surface of the wedge-shaped inserting rod 1761 abuts against the slot 1762, and the rotating rod 171 will be driven to rotate through the slot 1762, and then the rotating disk 2 can be driven to rotate. Further, the transmission ratio between the transmission rack 174 and the transmission gear 173 is designed according to the work needs. It can be ensured that the cooperation between the transmission rack 174 and the transmission gear 173 ensures that the rotating disk 2 can rotate 90°, that is, the fastener is conveyed to the next working station. More specifically, a toothless part 175 is also provided on the transmission rack 174. Therefore, when the servo cylinder 11 drives the motor 10 to reset, at this moment, the toothless part 175 will first contact the transmission gear 173, so the transmission gear 173 cannot rotate until the engaging part on the output shaft of the motor 10 is completely separated from the metal nail 7. At this moment, the transmission teeth on the transmission rack 174 begin to mesh with the transmission gear 173, and the rotating disk 2 is driven to rotate through the transmission gear 173, and the use effect is better.

[0041] In the embodiments provided by the present invention, multiple sets of supporting parts 15 are slidably connected to the workbench 1, and each supporting part 15 is respectively located below the fastening part 5. Preferably, the fastening part 5 includes four positioning blocks 21, and the four positioning blocks 21 form a positioning space, and the size of the positioning space is the same as the size of the terminal box 6. The supporting part 15 includes a plurality of support plates 151 slidably connected to the workbench 1, and the terminal box 6 is located above the support plates 151. At this moment, when the support plates 151 slide upward, the terminal box 6 will be jacked up. More specifically, the upward movement of the support plates 151 releases the restriction of the terminal box 6 from the fastening part 5 to facilitate subsequent blanking. The plurality of support plates 151 are fixedly connected by a connecting plate 152, which is more convenient to drive the plurality of support plates 151 to move synchronously. A reset member is further provided between the connecting plate 152 and the workbench 1. The reset member is preferably a reset spring, which can limit the state of the support plates 151, so that the support plates 151 are always located inside the rotating disk 2. Only when blanking is required, the supporting part 15 moves upward against the restriction of the reset member to meet the working needs.

[0042] A guiding and lifting member 16 is further provided between the supporting part 15 and the workbench 1. When the rotating disk 2 rotates, the supporting part 15 drives the assembled terminal box 6 to move upward through the guiding and lifting member 16 to release the restriction of the fastening part 5. The lifting action of the supporting part 15 completely depends on the power of the rotation of the rotating disk 2, and this power comes from the reset of the servo cylinder 11 (through the one-way transmission mechanism 17). This means that no additional driving sources such as cylinders, motors 10, hydraulic cylinders or electromagnets are required for the jacking action. And since the terminal box 6 is clamped inside the fastening part 5, there must be a force to drive the terminal box 6 to move upward during blanking. At this moment, the jacking action will definitely occur. At this moment, the supporting part 15 moves upward during the rotation of the rotating disk 2 (i.e., after processing is completed and the cylinder is reset). When the turntable rotates to a predetermined angle (i.e., the blanking station), the supporting part 15 is exactly lifted to the highest point, without the risk of timing disorder, and the use effect is excellent.

[0043] In the embodiments provided by the present invention, the guiding and lifting member 16 includes a guiding rod 161 fixedly connected to the connecting plate 152. The guiding rod 161 is slidably connected to the rotating disk 2 through an avoidance groove to avoid movement interference. A rotating groove 162 is formed in the workbench 1, and the guiding rod 161 is rotatably connected to the rotating groove 162. A stabilizing groove 163 is also formed in the workbench 1, and the stabilizing groove 163 is communicated with the rotating groove 162 through a guiding groove 164. More specifically, there are two guiding grooves 164, which are respectively arranged on both sides of the stabilizing groove 163 and are respectively communicated with the rotating groove 162. At the same time, the guiding groove 164 is in an inclined state. More specifically, the stabilizing groove 163 is formed on one side of the blanking groove 20. Therefore, during use, when multiple feeding mechanisms are used to respectively install the terminal box 6, the metal sheet 8, and the metal nail 7, the supporting portion 15 is always located inside the workbench 1 at this moment, that is, the guiding rod 161 is always rotating inside the rotating groove 162 at this time. After the metal nail 7 is installed into the terminal box 6, during the stroke of the servo cylinder 11 driving the motor 10 and the stamping portion 13 to reset, the rotating disk 2 is driven to rotate through the one-way transmission mechanism 17. During the stroke of the rotating disk 2 rotating at this moment, the guiding rod 161 will be driven to move from the rotating groove 162 to the side of the stabilizing groove 163 (the rotating disk rotates from the third working position to the fourth working position at this time). Specifically, when the guiding rod 161 moves through the guiding groove 164 to the stabilizing groove 163, the guiding rod 161 will drive a plurality of support plates 151 to move upward through the connecting plate 152, releasing the restriction on the terminal box 6 from the fastening portion 5, which is extremely convenient for subsequent blanking and has excellent use effects. That is, when the rotating disk 2 rotates from the third working position to the fourth working position, at this moment, the supporting portion 15 will be driven by the guiding and lifting member 16 to drive the terminal box 6 to move upward, so that the terminal box 6 is released from the restriction of the fastening portion 5, and the effect is better.

[0044] In the embodiment provided by the present invention, more specifically, a positioning frame 18 is fixedly connected to the support frame 3, and a blanking part 19 for driving the blanking of the assembled terminal box 6 is slidably connected inside the positioning frame 18. The blanking part 19 is in transmission connection with the first rack 141. More specifically, at this moment, when the fastener moves to the blanking groove 20 after the rotation of the rotating disk 2 when the assembly is completed, the blanking part 19 can be used to drive the fastener to be unloaded from the support part 15. Moreover, when the fastener moves to the position of the blanking groove 20 after the assembly is completed, with the rotation of the rotating disk 2, the terminal box 6 with the metal sheet 8 already installed in the previous one synchronously moves to the next station (i.e., from the third station to the fourth station), and during this process, the support part 15 is driven to move upward under the restriction of the guiding and lifting part 16, so that the assembled fastener is located above the fastening part 5, facilitating the blanking of the fastener. At this moment, only need to continue in the working process of the third station, drive the power frame 145 to repeat the above actions through the servo cylinder 11. When the metal nail 7 is installed inside the terminal box 6 and the stamping part 13 performs the stamping operation on the metal sheet 8, during the stroke when the buffer linkage mechanism 14 drives the stamping part 13 to move downward to stamp the metal sheet 8 at the third station, the assembled fastener at the fourth station is unloaded through the blanking part 19. This maximally compresses the production beat, simplifies the equipment structure, reduces the manufacturing cost and maintenance complexity, and significantly improves the reliability and synchronization accuracy of the system, which is a model of efficient automated assembly line design. Its core advantage lies in the highly coupled key actions in terms of time and power source, with better effects.

[0045] In the embodiment provided by the present invention, the blanking part 19 includes a blanking push block 191 slidably connected inside the positioning frame 18. A threaded rod 192 is rotatably connected to the positioning frame 18. The blanking push block 191 is threadedly connected to the threaded rod 192 through a threaded hole. When the threaded rod 192 rotates, it will drive the blanking push block 191 to slide inside the positioning frame 18. When the blanking push block 191 contacts the terminal box 6, it will drive the terminal box 6 to be unloaded. Specifically, a support rod 194 is rotatably connected to the positioning frame 18, and a power gear 195 is installed on the support rod 194. The power gear 195 meshes with the first rack 141, and the support rod 194 and the threaded rod 192 are in transmission connection through a synchronizing member 193. The synchronizing member 193 is a prior art, and its structure and working principle will not be elaborated here. At this moment, when the power frame 145 slides, it will drive the first rack 141 to slide on the support frame 3. When the first rack 141 meshes with the power gear 195, it drives the power gear 195 to rotate, and then through the cooperation of the support rod 194 and the synchronizing member 193, the threaded rod 192 can be driven to rotate. When the threaded rod 192 rotates, it will drive the blanking push block 191 to slide inside the positioning frame 18. When the blanking push block 191 contacts the terminal box 6, it will drive the terminal box 6 to be unloaded, thus greatly improving the blanking efficiency of the workpiece.

[0046] Two time-consuming actions that originally needed to be executed sequentially are completely overlapped in time. One movement stroke of the servo cylinder 11 drives two key actions simultaneously. The time for waiting for the blanking mechanism to act after the punching is completed is saved, and the time for waiting for the next punching action to start after the blanking is completed is also saved. The "idle period" of these two actions is completely eliminated. The effective working stroke of the cylinder (driving the punching head to descend) is fully utilized to drive another key process (blanking) simultaneously, and the energy utilization rate of the cylinder reaches the highest.

[0047] More specifically, the start and execution speeds of the blanking action are strictly synchronized with the punching action, which is ensured by the rigid connection of the rack drive and the same power source. The risk of timing mismatch that may occur under independent control is eliminated (such as the blanking starting too early before the punching is completed, or the blanking being delayed).

[0048] In the embodiment provided by the present invention, a positioning part is slidably connected inside the fastening part 5. The positioning part includes a positioning block 21 slidably connected to the rotating disk 2 through an adaptation slot, and a positioning spring 22 is arranged between the positioning block 21 and the rotating disk 2. Specifically, during use, the elastic force of the positioning spring 22 drives the positioning block 21 to be in a predetermined position. At this moment, when the metal sheet 8 is installed inside the terminal box 6, the elastic force of the positioning spring 22 drives the metal sheet 8 to abut against the inner wall of the terminal box 6, so as to be able to limit the state of the metal sheet 8 and prevent the metal sheet 8 from tipping over. When it is necessary to install the metal nail 7 inside the terminal box 6, at this moment, the clamping rod 71 on the metal nail 7 will be clamped into the clamping slot 81 on the metal sheet 8. At this time, when the metal nail 7 slides inside the terminal box 6, it will squeeze the metal sheet 8 to slide against the positioning block 21 and then slide to the other side of the terminal box 6, and then will squeeze the positioning spring 22. When the positioning block 21 contacts the inner wall of the terminal box 6, the punching operation on the metal sheet 8 can be realized to meet the working requirements.

[0049] Preferably, a detection part 23 is also cooperated on the workbench 1. The detection part 23 is located between the third station and the fourth station and is used for detecting the assembled fasteners. Specifically, the detection part 23 is a CCD camera. In the security prevention system, the generation of images mainly comes from CCD cameras at present. CCD is the abbreviation of charge coupled device. It can change light into charges, store and transfer the charges, and can also take out the stored charges to change the voltage. Therefore, it is an ideal CCD camera component. The CCD camera composed of it is widely used because of its small size, light weight, not affected by magnetic fields, and characteristics of anti-vibration and impact.
