Description

Technical Field

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

[0002] Terminal blocks are used to facilitate the connection of wires. For example, if two wires need to be connected at one time and disconnected at another, a terminal block can be used to connect them and disconnect them at any time without having to solder or twist them together, making operation quick and convenient. Specifically, in the industry, they are classified as connectors.

[0003] As the degree of industrial automation becomes higher and higher and the requirements for industrial control become more stringent and precise, the use of terminal blocks has gradually increased. With the development of the electronics industry, the scope of use of terminal blocks has become wider and wider, and the types have also increased.

[0004] As is known, terminal blocks are composed of metal sheets, metal nails, and a terminal box. When assembling the terminal blocks, existing assembly equipment uses a motor as a power source, transports the terminal box via a belt, and then manually inserts the metal sheets into the terminal box to complete the assembly of the terminal blocks. This assembly equipment consumes a lot of manpower, especially when manually squeezing the metal nails into the terminal box.

[0005] To improve work efficiency, related patents have been proposed in the prior art, such as the Chinese patent with authorization publication number CN222088484U, entitled "A Terminal Block Assembly Device." This patent discloses a terminal block assembly device comprising a box body, a clamping box fixedly connected to the bottom of the box body, a clamping device disposed within the clamping box, and an adjustment device disposed above the box body. Advantages of this invention include a more stable fixed installation of the terminal box and an adjustable mechanism based on the size of the terminal box, ensuring a more stable clamping of the terminal box during installation.

[0006] Another example is the Chinese patent with the authorization announcement number CN222884069U, entitled "An automatic assembly device for terminal blocks". The above patent discloses an automatic assembly device for terminal blocks, which solves the problem of poor performance of existing assembly devices. The device includes a support table, the top of which is fixedly provided with a first vibration disk, a second vibration disk, an assembly mechanism and a controller. The assembly mechanism is connected to the first vibration disk and the second vibration disk. The first vibration disk, the second vibration disk and the assembly mechanism are all electrically connected to the controller. The assembly mechanism consists of a first feeding frame, a first pushing assembly, a second feeding frame, a second pushing assembly and an extrusion docking assembly. The first feeding frame, the second feeding frame and the extrusion docking assembly are all fixedly connected to the top of the support table. The first pushing assembly is fixedly connected to one side of the first feeding frame, and the second pushing assembly is fixedly connected to one side of the second feeding frame. Through the automatic assembly device in the above patent, the terminal blocks can be automatically assembled, thereby improving assembly efficiency.

[0007] The existing technologies such as the above-mentioned patents can meet the assembly needs of fasteners to a certain extent. It is known that in order to facilitate the later use of fasteners, the metal nail and the terminal box are generally threaded, so a threaded hole that is compatible with the metal nail is opened on the terminal box. A plug rod is provided at the end of the metal nail, and a socket that is compatible with the plug rod is opened on the metal sheet. During the assembly process, the plug rod at the end of the metal nail needs to be inserted into the socket on the metal sheet, and then a piercing component is used to drive the metal sheet to deform so that the metal sheet is connected to the plug rod to meet the subsequent working needs of the fastener. In 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 plug rod is clamped into the socket on the metal sheet. After that, after driving the terminal box to rotate to the next station, a piercing component is used to drive the metal sheet to deform, and then a clamping blanking mechanism is used for blanking.

[0008] During the above operation, the metal nail needs to be threaded into the inside of the terminal box, and the extrusion operation can only be performed by using a driving source to drive the terminal box to rotate to the next workstation, which increases the workload. At the same time, due to the use of multiple driving sources, CNC technology is also required to make the extrusion mechanism accurately adapt to the multiple driving sources. The addition of CNC technology will not only lead to an increase in the overall equipment cost in the assembly and processing of fasteners, but also lead to an increase in the overall failure rate of the equipment, which has certain shortcomings.

[0009] It can be seen that how to realize the connection between the metal nail thread and the terminal box inside through the driving source on a device and then passively connect the metal nail to the metal sheet is a technical problem that needs to be solved urgently. 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 objectives, 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 multiple feeding mechanisms, the feeding mechanisms being located on one side of the workbench, a rotating disk being rotatably connected to the workbench, multiple sets of fastening parts being installed on the rotating disk, and the rotating disk sequentially loads terminal boxes, metal sheets and metal nails 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 provided on the workbench; a pier pressing part is vertically connected to the support frame, and the pier pressing part and the servo cylinder are connected in transmission via a buffer linkage mechanism; the servo cylinder drives the motor to install the metal nail into the terminal box, and then continues to drive the pier pressing part to connect the metal sheet and the metal nail through 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 connected by a gear transmission member; the motor is slidably connected to the workbench through a sliding plate, and a buffer part is provided between the power frame and the sliding plate.

[0013] Furthermore, the buffer portion 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 provided between the sliding rod and the bearing cylinder.

[0014] Furthermore, the rotating disk and the power frame are connected through 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, and a one-way transmission part is provided between the transmission rod and the rotating rod; a gear power part is 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 provided on the rotating rod, and an abutment spring is provided 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] Furthermore, the workbench is slidably connected to a plurality of groups of support parts, and each support part is 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 plate, the plurality of support plates are fixedly connected by connecting plates, and a reset part is also provided between the connecting plate and the workbench; a guide lifting part is also provided between the support part and the workbench, and when the rotating disk rotates, the support part drives the assembled terminal box to move upward through the guide lifting part to break away from the restriction of the fastening part.

[0017] Furthermore, the guide lifting member includes a guide rod fixedly connected to the connecting plate, and the guide rod is slidably connected to the rotating disk; a rotating groove is provided on the workbench, and the guide rod is rotatably connected to the rotating groove, and a stabilizing groove is also provided on the workbench, and the stabilizing groove and the rotating groove are connected through the guide groove.

[0018] Furthermore, a positioning frame is fixedly connected to the support frame, and a blanking portion for driving the terminal box to be blanked after assembly is slidably connected inside the positioning frame, and the blanking portion is transmission-connected to the first rack.

[0019] Furthermore, the unloading part includes a unloading push block slidably connected to the inside of the positioning frame, a threaded rod is rotatably connected to the positioning frame, and the unloading 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 engaged with the first rack, and the support rod and the threaded rod are connected through a synchronous member.

[0020] Furthermore, a positioning portion is slidably connected in the fastening portion, and the positioning portion includes a positioning block slidably connected to the rotating disk through an adapting groove, and a positioning spring is provided between the positioning block and the rotating disk.

[0021] Compared with the prior art, the beneficial effect of the present invention is that: during use, the automated fastener assembly equipment can load the terminal box, metal sheet and metal nail in sequence by rotating the disk in conjunction with the loading mechanism, and adjust the metal nail to the same horizontal line as the threaded hole on the terminal box. Then, the servo cylinder drives the motor to move horizontally on the workbench so that the motor output shaft is engaged with the metal nail. At the same time as the motor starts, the servo cylinder drives the motor to slide horizontally on the workbench to install the metal nail inside the terminal box, and then the motor automatically shuts down. During the horizontal sliding stroke of the servo cylinder driving the motor on the workbench, the buffer linkage drives the pier pressing part to move downward. 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 and continues to drive the pier pressing part downward, causing the metal sheet to deform so that the clamping rod of the metal nail is engaged with the clamping groove on the metal sheet, so that the clamping rod and the clamping groove are engaged, meeting the normal use of the subsequent fasteners. When the pressing part contacts the metal sheet, the motor stops sliding due to the buffer linkage mechanism, preventing motion interference. This stops the motor from sliding, transferring the thrust of the servo cylinder to the pressing part for compression. This effectively overlaps or seamlessly connects the previously sequential processes of "screwing" and "pressing."

[0022] Previously, it was necessary to first thread a metal nail into the terminal box before rotating the terminal box to the next station for the extrusion process. Now, a servo cylinder drives the motor to install the metal nail, and the pier pressing process is completed directly through the buffer linkage mechanism. There is no need to wait for the terminal box to rotate to switch stations. This greatly shortens the time between process changes, 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 rod is determined during the screwing process. That is, the rod is already inserted into the slot. Rotating to the next station will inevitably introduce slight positioning errors (mechanical clearance, vibration, etc.), which may cause the rod and socket to be misaligned during pier pressing. Completing all operations in the same position completely eliminates this secondary positioning error, ensuring optimal alignment of the rod and socket during pier pressing, and improving the consistency and reliability of the connection.

[0024] The existing technical process involves multiple drive sources, which are used to drive the motor, rotate the terminal box, and perform subsequent extrusion operations. The improved design uses a servo cylinder as the core drive, combined with a buffer linkage mechanism, to integrate some drive functions, reducing the number of required drive sources and directly reducing the equipment's drive system procurement costs. Since the complex CNC technology is no longer required to precisely coordinate multiple drive sources, the corresponding CNC system and related components are eliminated, the overall structure of the equipment is simplified, and the manufacturing difficulty is reduced. This also helps to reduce the initial purchase cost of the equipment and subsequent maintenance costs, improving the equipment's cost-effectiveness. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] See also Figures 1-16 The 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 feeding mechanisms, the feeding mechanisms being located on one side of the workbench 1, and a rotating disk 2 being rotatably connected to the workbench 1, and multiple groups of fastening parts 5 being installed on the rotating disk 2, and the rotating disk 2 sequentially loads terminal boxes 6, metal sheets 8 and metal nails 7 through the feeding mechanism, a motor 10 being slidably connected to the workbench 1, and the output shaft of the motor 10 being clamped with the metal nail 7; a servo cylinder 11 for driving the motor 10 to slide is provided 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 through the buffer linkage mechanism 14 to connect the metal sheet 8 with the metal nail 7.

[0045] Specifically, the automated fastener assembly equipment includes a workbench 1 and a support frame 3 mounted on the workbench 1. A controller 4 is also provided on the workbench 1 for controlling the operation of the entire equipment. Specifically, multiple sets of support members are provided on the bottom of the workbench 1 to improve the stability of the entire assembly equipment during operation. The equipment also includes multiple loading mechanisms, located on one side of the workbench 1, for loading the various components of the fasteners. A rotating disk 2 is rotatably connected to the workbench 1, and multiple sets of fastening portions 5 are mounted on the rotating disk 2 for restraining the terminal box 6. The rotating disk 2 sequentially loads the terminal box 6, metal sheet 8, and metal nail 7 onto the loading mechanism. Specifically, there can be three loading mechanisms, each located on the side of the workbench 1, for loading the terminal box 6, metal sheet 8, and metal nail 7, respectively. Specifically, the workbench 1 is provided with four workstations: a first station, a second station, a third station, and a fourth station. During this working process, the first loading mechanism is first used (that is, the first work station, used for loading the terminal box 6) to load the terminal box 6 into the fastening part 5, and the fastening part 5 restricts the terminal box 6; then the rotating disk 2 rotates to a certain stroke, and the second loading mechanism loads the metal sheet 8 into the terminal box 6 (at this moment, it is working at the second work station, and the metal sheet 8 is installed into the terminal box 6); then the rotating disk 2 continues to rotate, and after rotating to a certain stroke, the third loading mechanism is used (at this moment, it is working at the third work station, and is used to install the metal nail 7 into the terminal box 6) to load the metal nail 7 to a 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 needs of the fasteners; after the assembly is completed, a discharge trough 20 is opened on the workbench 1, that is, the discharge trough 20 is the fourth work station, which is convenient for the discharge of fasteners after the assembly is completed. After that, the rotating disk 2 will rotate inside the workbench 1, from the first station to the second station, the third station, the fourth station, and then from the fourth station back to the first station in a reciprocating cycle. The loading mechanism can be a vibrating loading disk in conjunction with a robotic arm for loading. The structure and working principle of the vibrating loading disk and the robotic arm are all existing technologies and will not be described in detail here.

[0046] More specifically, a threaded hole is provided on the terminal box 6, and the metal nail 7 is threadedly connected to the terminal box 6 through the threaded hole. 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 to the inside of 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. At this moment, 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 the distance between the metal sheet 8 and the terminal box 6 needs to be adjusted according to work needs in the later stage, at this time, it is only necessary to drive the metal nail 7 to rotate, which will drive the metal sheet 8 to slide in the terminal box 6 to meet work needs.

[0047] A motor 10 is slidably connected to the workbench 1, and the output shaft of the motor 10 engages with the metal nail 7. The motor 10 output shaft is provided with a snap-fitting portion. Specifically, the end of the metal nail 7 has a cross-shaped groove, and the snap-fitting portion on the motor 10 output shaft engages with the cross-shaped groove. When the snap-fitting portion is engaged within the cross-shaped groove, rotation of the motor 10 output shaft drives the metal nail 7 through the cross-shaped groove, thereby achieving the desired installation of the metal nail 7 within the terminal box 6 and improving the working effect.

[0048] The workbench 1 is provided with a servo cylinder 11 for driving the motor 10 to slide, which provides power for the sliding of the motor 10, 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 a solid metal material with a relatively 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 and the servo cylinder 11 are connected by a buffer linkage mechanism 14, that is, the movement of the pier pressing part 13 is also driven by the servo cylinder 11, which has a better effect. 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, metal sheet 8, and metal nail 7 are loaded sequentially by rotating the disk 2 in coordination with the loading mechanism, and the metal nail 7 is adjusted to be flush with the threaded hole in the terminal box 6. The servo cylinder 11 then drives the motor 10 to move horizontally on the workbench 1, so that the output shaft of the motor 10 engages with the metal nail 7. As the motor 10 starts, the servo cylinder 11 drives the motor 10 to slide horizontally on the workbench 1, installing the metal nail 7 inside the terminal box 6. The motor 10 then automatically shuts down. The servo cylinder 11 drives the motor 10 to slide horizontally on the workbench 1, driving the pressing portion 13 downward through the buffer linkage. At this moment, when the metal nail 7 is installed inside the terminal box 6, the servo cylinder 11 drives the pressing portion 13 into contact with the metal sheet 8 through the buffer linkage mechanism 14, and continues to drive the pressing portion 13 downward. The metal sheet 8 deforms, so that the clamping rod 71 of the metal nail 7 is engaged with the clamping groove 81 on the metal sheet 8. The clamping rod 71 and the clamping groove 81 engage, meeting the normal use of the subsequent fastener. And when the pressing portion 13 contacts the metal sheet 8, the motor 10 stops sliding due to the action of the buffer linkage mechanism 14, and no motion interference occurs. At this moment, when the motor 10 stops sliding, it transmits the thrust of the servo cylinder 11 to the pressing portion 13 for squeezing. This is equivalent to partially overlapping or closely connecting the two originally serial processes of "screwing" and "pressing".

[0049] Previously, 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 the extrusion operation. 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. This greatly shortens the time between process changes, making the entire assembly process more compact and coherent, and significantly improving production efficiency.

[0050] After the metal nail 7 is screwed into place, the relative position of the metal sheet 8 and the rod is already determined during the screwing process. That is, the rod is already inserted into the slot 81. Rotating to the next station will inevitably introduce slight positioning errors (mechanical play, vibration, etc.), which may cause the rod and socket to be misaligned during the pier pressing. The new solution completes all operations in the same position, completely eliminating this secondary positioning error, ensuring optimal alignment of the rod and socket during pier pressing, and improving the consistency and reliability of the connection.

[0051] The existing technology involves multiple drive sources, which are used to drive the motor 10, the terminal box 6 to rotate, and the subsequent extrusion operations. The improved design uses 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 equipment's purchase cost in terms of the drive system. Since there is no longer a need for complex numerical control technology to adapt to the precise coordination of multiple drive sources, 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 also helps to reduce the initial purchase cost of the equipment and subsequent maintenance costs, thereby improving the cost-effectiveness of the equipment.

[0052] After the equipment structure is simplified, the number of parts is reduced. The workload of maintenance personnel during daily inspections, troubleshooting, and parts replacement is significantly reduced. Problems can be located and solved more quickly, which improves the maintenance efficiency of the equipment and ensures the normal production operation of the equipment.

[0053] 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. The pier pressing part 13 and the first rack 141 are connected via a gear transmission member. The servo cylinder 11 is connected to the power frame 145 and is used 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 multiple sets of limiting telescopic rods are provided 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. The 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 drives the long gear 142 to rotate, transferring force to the second rack 143. The second rack 143 drives the mounting plate 131 downward, facilitating the subsequent pier pressing operation and meeting work needs. The motor 10 is slidably connected to the workbench 1 through the sliding plate 9. Preferably, multiple sets of limiting parts 12 are provided between the sliding plate 9 and the workbench 1 to improve the stability of the sliding plate 9 when sliding, thereby achieving a better use effect. At the same time, the limiting part includes a limiting block fixedly connected to the bottom of the sliding plate 9. 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. The position and length of the limiting groove can be set according to work needs. A buffer portion 144 is provided between the power frame 145 and the sliding plate 9. The buffer portion 144 includes a supporting tube 1441 fixedly connected to the power frame 145, and a sliding rod 1443 fixedly connected to the sliding plate 9 and slidably connected to the supporting tube 1441. A buffer spring 1442 is provided between the sliding rod 1443 and the supporting tube 1441. Specifically, the elastic force of the buffer spring 1442 drives the sliding rod 1443 and the supporting tube 1441 away from each other. That is, during use, when the servo cylinder 11 drives the power frame 145 to slide, 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. During this process, the servo cylinder 11 continuously drives the power frame 145 to slide. At this point, the sliding plate 9 stops sliding due to the restriction of the limiter 12. At this point, as the power frame 145 moves on the workbench 1, it drives the slide rod 1443 to slide inside the carrier cylinder 1441, thereby squeezing the buffer spring 1442 to offset the force driving the motor 10 forward. As the power frame 145 continues to slide, it drives the first rack 141 to slide on the support frame 3. As the first rack 141 slides, it drives the long gear 142 to rotate, transmitting force to the second rack 143. This, in turn, drives the mounting plate 131 downward, performing a piercing operation on the metal sheet 8 to meet work requirements.The servo cylinder 11 moves accurately and quickly, and can complete the driving of the motor 10 and the operation of 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.

[0054] In the embodiment provided herein, the rotating disk 2 is connected to the power frame 145 via a one-way transmission mechanism 17. Specifically, when the servo cylinder 11 is required to drive the motor 10 to assemble the metal nail 7 and the pressing unit 13 to press the metal sheet 8, the rotating disk 2 stops rotating. Once the metal nail 7 is installed within the terminal box 6 and the pressing unit 13 has completed the pressing operation, the servo cylinder 11 is used to reset the motor 10 and the pressing unit 13. During the reset process of the motor 10 and the pressing unit 13, the one-way transmission mechanism 17 drives the rotating disk 2 to rotate, meeting the required operation. The reset action of the servo cylinder 11 after the processing is completed is typically a necessary action that does not directly generate processing value. By providing a one-way transmission element, the energy released during the cylinder reset is effectively "captured" by the one-way transmission mechanism 17 and converted into power to drive the rotating disk 2, thus avoiding the waste of this energy and achieving a better effect.

[0055] 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. The workbench 1 is also rotatably connected to a transmission rod 172. A one-way transmission unit 176 is provided between the transmission rod 172 and the rotating rod 171. A gear power unit is provided between the power frame 145 and the transmission rod 172. Specifically, the gear power unit includes a transmission gear 173 mounted on the transmission rod 172. A transmission rack 174 is fixedly connected to the power frame 145, and the transmission gear 173 meshes with the transmission rack 174. The one-way transmission portion 176 includes a wedge-shaped rod 1761, which is slidably connected to the transmission rod 172 via a sliding groove. The rotating rod 171 is provided with a slot 1762 that matches the wedge-shaped rod 1761. An abutment spring 1763 is provided between the wedge-shaped rod 1761 and the slot. The elastic force of the abutment spring 1763 drives the wedge-shaped rod 1761 to engage with the slot 1762. In other words, during use, when the metal nail 7 is assembled into the terminal box 6 and the metal sheet 8 needs to be pressed, the power frame 145 drives the transmission rack 174 to slide, which drives the transmission gear 173 to rotate, thereby driving the transmission rod 172 to rotate. At this time, the rotation of the transmission rod 172 causes the wedge surface of the wedge-shaped rod 1761 to abut against the inclined surface of the slot 1762, and the rotating rod 171 cannot be driven to rotate. Conversely, when the transmission rack 174 slides in the opposite direction, it drives the transmission rod 172 to rotate through the cooperation of the transmission gear 173. At this time, the straight surface of the wedge-shaped insert 1761 contacts the slot 1762, which drives the rotation rod 171 to rotate through the slot 1762, and thus drives the rotation of the rotating disk 2. Furthermore, the transmission ratio between the transmission rack 174 and the transmission gear 173 is designed according to the working requirements. It can be guaranteed that the cooperation between the transmission rack 174 and the transmission gear 173 ensures that the rotating disk 2 can rotate 90 degrees, that is, the fastener is transported to the next work station. More specifically, the transmission rack 174 is further provided with a toothless portion 175. Therefore, when the servo cylinder 11 drives the motor 10 to reset, the toothless portion 175 will first contact the transmission gear 173, so the transmission gear 173 cannot rotate until the engaging portion on the output shaft of the motor 10 is completely separated from the metal nail 7. At this time, the transmission teeth on the transmission rack 174 begin to engage with the transmission gear 173, and the rotating disk 2 is driven to rotate through the transmission gear 173, which has a better use effect.

[0056] In the embodiment provided by the present invention, a plurality of groups of support parts 15 are slidably connected to the workbench 1, and each support 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, the size of which is consistent with the size of the terminal box 6. The support 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 lifted 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 unloading. The plurality of support plates 151 are fixedly connected by a connecting plate 152, which makes it more convenient to drive the plurality of support plates 151 to move synchronously. A reset member is also 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 plate 151 so that the support plate 151 is always located inside the rotating disk 2. Only when unloading is required, the support part 15 moves upward to overcome the restriction of the reset member to meet work needs.

[0057] A guide lift 16 is provided between the support portion 15 and the workbench 1. When the rotating disk 2 rotates, the support portion 15, through the guide lift 16, drives the assembled terminal box 6 upward, freeing it from the restraints of the fastening portion 5. The lifting action of the support portion 15 relies entirely on the power of the rotating disk 2's rotation, which in turn is generated by the reset of the servo cylinder 11 (via a one-way transmission mechanism 17). This means that the lifting action does not require additional drive sources such as cylinders, motors 10, hydraulic cylinders, or electromagnets. Furthermore, because the terminal box 6 is secured within the fastening portion 5, a force driving the terminal box 6 upward is necessary during unloading, and the lifting action is inevitable. The upward movement of the support portion 15 occurs during the rotation of the rotating disk 2 (i.e., when processing is completed and the cylinder is reset). When the rotating disk reaches the predetermined angle (i.e., the unloading position), the support portion 15 is precisely lifted to its highest point, eliminating the risk of timing errors and providing excellent performance.

[0058] In the embodiment provided by the present invention, the guide lifting member 16 includes a guide rod 161 fixedly connected to the connecting plate 152. The guide rod 161 is slidably connected to the rotating disk 2 via an avoidance groove to prevent motion interference. The workbench 1 is provided with a rotating groove 162, and the guide rod 161 is rotatably connected to the rotating groove 162. The workbench 1 is also provided with a stabilizing groove 163, and the stabilizing groove 163 and the rotating groove 162 are connected via a guide groove 164. More specifically, there are two guide grooves 164, one on each side of the stabilizing groove 163, and each is connected to the rotating groove 162. At the same time, the guide grooves 164 are inclined. More specifically, the stabilizing groove 163 is provided on one side of the feed chute 20. Therefore, during use, when multiple loading mechanisms are used to respectively install the terminal box 6, the metal sheet 8, and the metal nail 7, the support portion 15 is always located inside the workbench 1, that is, the guide rod 161 is always rotating inside the rotating groove 162. After the metal nail 7 is completely installed inside the terminal box 6, the servo cylinder 11 drives the motor 10 and the pier pressing portion 13 to reset, and the one-way transmission mechanism 17 drives the rotating disk 2 to rotate. At this time, during the rotating disk 2's rotation, the guide rod 161 is driven to move from the rotating groove 162 toward the stabilizing groove 163 (the rotating disk is now rotating from the third station to the fourth station). Specifically, when the guide rod 161 passes through the guide groove 164 and moves toward the stabilizing groove 163, it drives the multiple support plates 151 upward through the connecting plate 152, freeing the terminal box 6 from the fastening portion 5, facilitating subsequent unloading, and achieving excellent results. That is, when the rotating disk 2 rotates from the third station to the fourth station, the support portion 15 is driven by the guide lifting member 16, causing the support portion 15 to move upward with the terminal box 6, thereby freeing the terminal box 6 from the fastening portion 5, achieving even better results.

[0059] In the embodiment provided by the present invention, more specifically, a positioning frame 18 is fixedly connected to the support frame 3. A discharge portion 19 is slidably connected within the positioning frame 18 for driving the discharge of the assembled terminal box 6. The discharge portion 19 is in transmission connection with the first rack 141. More specifically, when the assembled fastener moves to the discharge chute 20 through the rotation of the rotating disk 2, the discharge portion 19 can be used to drive the fastener to be discharged from the support portion 15. Moreover, when the assembled fastener moves to the discharge chute 20, as the rotating disk 2 rotates, the terminal box 6 located on the previous metal sheet 8 is synchronously moved to the next station (i.e., from the third station to the fourth station). During this process, the support portion 15 is restricted by the guide lifting member 16 and driven to move upward, so that the assembled fastener is located above the fastening portion 5, facilitating the discharge of the fastener. At this point, all that is needed is to continue working at the third station, using the servo cylinder 11 to drive the power rack 145 to repeat the above-mentioned actions. As the metal nail 7 is installed inside the terminal box 6 and the pressing unit 13 performs the pressing operation on the metal sheet 8, the buffer linkage mechanism 14 drives the pressing unit 13 downward to press the metal sheet 8 at the third station. The fasteners assembled at the fourth station are then unloaded via the unloading unit 19. This maximizes the compression of production cycles, simplifies the equipment structure, reduces manufacturing costs and maintenance complexity, and significantly improves system reliability and synchronization accuracy, making it a model for efficient automated assembly line design. Its core advantage lies in the highly coupled timing and power source of key actions, resulting in better results.

[0060] In the embodiment provided by the present invention, the unloading portion 19 includes a unloading push block 191 that is slidably connected to the interior of the positioning frame 18. A threaded rod 192 is rotatably connected to the positioning frame 18. The unloading push block 191 is threadedly connected to the threaded rod 192 through a threaded hole. When the threaded rod 192 rotates, it drives the unloading push block 191 to slide inside the positioning frame 18. When the unloading push block 191 contacts the terminal box 6, it drives the terminal box 6 to unload. Specifically, a support rod 194 is rotatably connected to the positioning frame 18. A power gear 195 is installed on the support rod 194. The power gear 195 is meshed with the first rack 141, and the support rod 194 and the threaded rod 192 are connected by a synchronous member 193. The synchronous member 193 is a prior art, and its structure and working principle are not described in detail 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 engages with the power gear 195, it will drive the power gear 195 to rotate, and then it can drive the threaded rod 192 to rotate through the cooperation of the support rod 194 and the synchronous member 193. When the threaded rod 192 rotates, it will drive the unloading push block 191 to slide inside the positioning frame 18. When the unloading push block 191 contacts the terminal box 6, it will drive the terminal box 6 to unload, thereby greatly improving the unloading efficiency of the workpiece.

[0061] Two time-consuming actions that would otherwise need to be performed sequentially are now completely overlapped in time. A single stroke of servo cylinder 11 simultaneously drives both critical actions. This eliminates the time it takes to wait for the unloading mechanism to operate after the ram is completed, and also eliminates the time it takes to wait for the next ram to begin after unloading. The "window period" between these two actions is completely eliminated. The cylinder's effective working stroke (driving the ram downward) is fully utilized to simultaneously drive the other critical process (unloading), maximizing cylinder energy utilization.

[0062] More specifically, the start and execution speed of the unloading action are strictly synchronized with the pier pressing action, ensured by the rigid connection of the rack drive and the common power source. This eliminates the risk of timing mismatch that can occur with independent control (such as unloading starting too early before the pier pressing is complete, or unloading being delayed).

[0063] In the embodiment provided by the present invention, a positioning portion is slidably connected within the fastening portion 5. The positioning portion includes a positioning block 21 that is slidably connected to the rotating disk 2 via an adapter groove, and a positioning spring 22 is provided 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 a predetermined position. At this time, 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, thereby limiting the state of the metal sheet 8 and preventing the metal sheet 8 from tipping over. When the metal nail 7 needs to be installed inside the terminal box 6, the clamping rod 71 on the metal nail 7 will be clamped into the clamping groove 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 and abut against the positioning block 21, then slide toward the other side of the terminal box 6, thereby squeezing the positioning spring 22. When the positioning block 21 contacts the inner wall of the terminal box 6, the metal sheet 8 can be pressed, meeting the working requirements.

[0064] Preferably, an inspection unit 23 is also provided on the workbench 1, located between the third and fourth workstations, for inspecting assembled fasteners. Specifically, the inspection unit 23 is a CCD camera. In security systems, images are currently primarily generated from CCD cameras. CCD, short for charge-coupled device, converts light into electrical charge, stores and transfers it, and can also extract stored charge to change voltage. Therefore, CCD cameras are ideal components for CCD cameras. CCD cameras constructed with CCDs are widely used due to their small size, light weight, immunity to magnetic fields, and resistance to vibration and impact.

[0065] It should be noted that the electrical equipment involved in this application can be powered by batteries or external power supply.
