Description

Technical Field

[0001] This application relates to the technical field of intelligent assembly equipment, and in particular to an automatic assembly equipment for terminal blocks. Background Technology

[0002] Wall switches and wall sockets, as terminal interfaces of electrical systems, are widely used in various scenarios such as residential homes, commercial buildings, and public facilities. They are core components for realizing power distribution and control of electrical equipment, and their structural stability and assembly process directly affect electrical safety and user experience. Taking the most widely used typical wall switch as an example, its overall structure consists of three core functional components: first, the base, which serves as the installation foundation and supports all internal electrical components such as the terminal block and conductive plates, ensuring a neat layout of components; second, the contact assembly, which realizes the circuit opening and closing through the contact and separation of the contacts and is the core execution part of the switch function; and third, the front cover, which serves to shield the internal components.

[0003] In related technologies, the base of a wall switch also requires the installation of a terminal block, a conductive plate, and wiring screws. The terminal block has an integrally formed limiting sleeve on its top surface and wiring screw holes on its vertical side for the wiring screws to screw into. The conductive plate has limiting through holes for the limiting sleeve to engage. The assembly process consists of three steps: first, aligning the limiting through holes of the conductive plate with the limiting sleeve of the terminal block and engaging them to complete the initial positioning; then, using a special riveting tool, bending the upper edge of the limiting sleeve outwards to achieve a firm connection between the conductive plate and the terminal block through mechanical deformation; finally, screwing the wiring screws one by one into the wiring screw holes of the terminal block, and finally installing the combined structure of the three components inside the base.

[0004] The aforementioned riveting process (i.e., bending and fixing the limiting sleeve) and the tightening process of the wiring screws generally need to be completed on different dedicated processing tables. Workpiece transfer is required between these two processes: the operator must first complete the riveting of the conductive sheet to the wiring base at the riveting station, then move the semi-finished base to the screw tightening station, and re-clamp and position it before the screw can be screwed in. This process increases the time cost of workpiece handling and, overall, restricts the efficiency of large-scale production of wall switches, indicating room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide an automatic assembly device for terminal blocks, which solves the problem of low assembly efficiency of terminal blocks, conductive plates and terminal screws in the above-mentioned related technologies.

[0006] The automatic assembly equipment for terminal blocks provided in this application adopts the following technical solution: An automatic terminal block assembly device includes a base, with several casters fixed on the bottom surface of the base. A tooling disc is rotatably mounted on the top surface of the base in a horizontal direction, and a drive component for rotating the tooling disc is fixed inside the tooling disc. Several clamping seats are fixed on the outer edge of the top surface of the tooling disc, and clamping slots for terminal blocks to be inserted are formed on the top surface of the clamping seats. A first feeding component for feeding terminal blocks, a second feeding component for feeding conductive sheets, and a third feeding component for feeding terminal screws are fixed around the tooling disc on the top surface of the base. A first clamping component clamps the terminal blocks fed by the first feeding component into the clamping slots, a second clamping component inserts the conductive sheets fed by the second feeding component into the terminal blocks, and a third clamping component screws fed by the third feeding component into the terminal screw holes are fixed on the base. A riveting assembly and a discharging assembly are fixed on the base between the second and third clamping components.

[0007] By adopting the above technical solution, a rotatable tooling tray is set on the base, and the first, second, and third feeding components and corresponding clamping components are integrated around the tooling tray. Simultaneously, riveting and unloading components are configured, realizing the integrated assembly process of the terminal block, conductive sheet, and wiring screw. The rotation of the tooling tray drives the workpiece on the clamping seat to sequentially pass through the terminal block feeding, conductive sheet installation, riveting, screw insertion, and finished product unloading stations, eliminating the traditional process of handling and repeatedly clamping workpieces between different processing tables, significantly reducing process connection time. The unified clamping and positioning method also reduces repeated positioning errors and improves assembly accuracy. The coordinated cooperation of all components forms a continuous automated production process, effectively solving the problem of low efficiency in the original decentralized processes and significantly improving the large-scale production efficiency of the core components of the wall switch.

[0008] Optionally, the discharge assembly includes a discharge slide slidably mounted on the top surface of the base, and a discharge groove inclined downward in the direction away from the tooling plate is formed on the top surface of the discharge slide; a fourth clamping member is fixed on the base to clamp the finished workpiece from the clamping slot into the discharge groove; and a collection bag with an upward opening is installed on the vertical side of the base and located below the lower opening of the discharge groove.

[0009] By adopting the above technical solutions, the inclined discharge chute and the discharge groove on the top surface can guide the finished workpiece to slide down naturally by gravity without the need for additional power. The fourth clamping component can accurately clamp the finished product in the clamping slot to the discharge chute, replacing manual transfer and reducing labor costs and operational errors. The collection bag on the vertical side of the base is located below the opening on the lower side of the chute, which can directly receive the sliding finished product, preventing the workpiece from falling and getting damaged. At the same time, it can achieve centralized storage, which is convenient for subsequent unified sorting. This further improves the automated production closed loop of the equipment and enhances the overall production efficiency.

[0010] Optionally, a support frame is provided on the vertical side of the base, the lower edge of the support frame is rotatably connected to the lower part of the vertical side of the base, and a support frame is vertically fixed on the upper edge of the support frame; the support frame is in a horizontal state when the support frame is in the vertical upward state, a locking member is provided on the bottom surface of the discharge slide to limit the support frame in this state, and a limiting member is provided on the top surface of the support frame to clamp and fix the upper edge of the collection bag.

[0011] By adopting the above technical solution, when the support frame is vertical, the support frame is horizontal and limited by locking components. These components, together with the limiting components, can stably clamp the upper edge of the collection bag, preventing the bag from shifting when the workpiece slips, thus ensuring storage stability. Simultaneously, the support frame can rotate around the base, allowing for subsequent adjustments to its state as needed (such as conversion into a maintenance support), breaking the functional limitations of traditional fixed storage structures. The overall design not only enhances the reliability of the material collection process but also provides a structural foundation for equipment maintenance and other scenarios, improving the flexibility and practicality of the equipment.

[0012] Optionally, the limiting component includes a limiting frame whose side edge is rotatably connected to the upper edge of the support frame, and a torsion spring that drives the limiting frame to rotate toward the support frame.

[0013] By adopting the above technical solution, the torsion spring can continuously apply a rotational force towards the support frame to the limiting frame, ensuring that the limiting frame stably clamps the upper edge of the collection bag under normal conditions without the need for continuous manual force, thus preventing the collection bag from shifting when the workpiece slips. When it is necessary to remove the collection bag, simply apply external force to push the limiting frame away from the support frame to release the fixation. The operation is simple and quick, requiring no additional tools. The overall structure is streamlined and highly automated, which not only improves the reliability of the collection bag fixation but also reduces manual operation costs and adapts to the automated production rhythm of the equipment.

[0014] Optionally, the locking component includes a locking rod fixed to the bottom edge of the discharge slide, and a locking block is fixed on the top surface of the support frame when the support frame is in a vertical state. The locking block has a locking notch. The top surface of the base is provided with a power component that drives the discharge slide to a locked state and an unlocked state. The locking rod slides into the locking notch when the discharge slide is in the locked state and slides out of the locking notch when it is in the unlocked state.

[0015] By adopting the above technical solution, when the power component drives the discharge slide, the locking rod can accurately slide into or out of the locking notch of the locking block, thereby quickly fixing or releasing the support frame in a vertical position without manual operation, improving the efficiency of equipment adjustment. In the locked state, the cooperation between the locking rod and the locking notch can stably restrict the position of the support frame, ensuring the stability of the collection bag after installation. In the unlocked state, it is convenient for the support frame to rotate and switch to other functional states (such as maintenance support). The overall structure achieves reliable locking through mechanical cooperation, and the operation is automated, adapting to the overall automated operation requirements of the equipment.

[0016] Optionally, the base has a receiving cavity on its vertical side facing the support frame, and a cover plate for sealing the opening of the receiving cavity is detachably installed. When the receiving cavity is sealed, the outer side of the cover plate abuts against the inner side of the support frame.

[0017] By adopting the above technical solution, the receiving cavity can be used to store tools, accessories, etc., improving the equipment's storage capacity; the cover plate sealing the receiving cavity can protect the internal items. Furthermore, when the outer side of the cover plate abuts against the inner side of the vertical support frame, the support frame can provide additional restraint for the cover plate, preventing it from loosening. This not only strengthens the cover plate's fixing effect but also makes full use of the existing structure, resulting in a simple and practical design.

[0018] Optionally, the support frame can be rotated to a horizontal position away from the base, at which point the bottom surface of the support frame is flush with the bottom surface of the moving wheels.

[0019] By adopting the above technical solution, when the equipment needs maintenance, the support frame is rotated to a horizontal state away from the base, and the bottom surface of the support frame is flush with the bottom surface of the moving wheel, which can serve as a stable step for maintenance personnel to stand on, without the need for additional auxiliary facilities, thus reducing the difficulty of maintenance operations; while during daily production, the support frame is fixed vertically to be used in conjunction with the collection bag, serving two purposes in one.

[0020] Optionally, two coaxial control rods are slidably mounted on opposite sides of the support frame; the support frame has a support through hole for the control rods to pass through, and limiting baffles are fixed on both ends of the control rods. When the two mutually close limiting baffles slide towards each other as the two control rods slide, they can slide to abut against each other and be detachably fixed.

[0021] By adopting the above technical solution, when the support frame is rotated to a horizontal position to serve as a maintenance step, the two opposing control rods can slide in opposite directions to make the limiting baffles that are close to each other abut against each other. Then, through detachable fixing (such as wing screws), the overall load-bearing capacity and deformation resistance of the support frame can be enhanced, and the step can be prevented from shaking when maintenance personnel stand on it. The sliding design of the control rods through the support through holes ensures that the adjustment process is stable and controllable, and the limiting baffles can prevent the control rods from slipping off.

[0022] Optionally, the base has positioning rods located on both sides of the cover plate that slide vertically along the vertical direction on the vertical side facing the support frame. The base is provided with an elastic pressing member that drives the positioning rods to slide upward. A guide arc surface is fixed at the upper edge of the positioning rod. When the support frame is in a vertically upward state, the two control rods can slide in opposite directions. At this time, the two mutually spaced limiting baffles can press the positioning rods downward along the guide arc surface. At this time, the lower end face of the positioning rod is flush with the bottom surface of the moving wheel.

[0023] By adopting the above technical solution, when the support frame is vertical, the opposing sliding control rods' limit baffles will press the positioning rod downwards along the guide arc surface until the lower end of the positioning rod is flush with the bottom surface of the moving wheel. Together with the moving wheel, they support the base, significantly improving the stability of the equipment during operation and preventing equipment shaking caused by operations such as tooling plate rotation. The elastic pressing component can automatically move the positioning rod upwards when the control rod resets, without affecting the subsequent rotation and switching states of the support frame. The overall design cleverly utilizes existing structural linkages, requiring no additional power, thus enhancing equipment stability without increasing operational complexity.

[0024] Optionally, the elastic compression member includes a spring in a compressed state, a guide block fixed on the base, and a protruding plate fixed on the outer periphery of the positioning rod. The protruding plate is located above the guide block, and the guide block has a guide hole for the positioning rod to pass through. The two ends of the spring are fixedly connected to the protruding plate and the side of the guide block that are close to each other.

[0025] By adopting the above technical solution, the compressed spring continuously applies an upward elastic force to the protruding plate, causing the positioning rod to move upward; the guide block and guide hole cooperate to ensure smooth sliding of the positioning rod. When the control rod is released from compression, the positioning rod can quickly return to its original position without affecting the rotation of the support frame. The structure is simple and reliable, and adaptable to the automation requirements of the equipment.

[0026] In summary, this application includes the following beneficial technical effects: The rotation of the tooling tray can drive the workpiece on the clamping seat to pass through the terminal block loading, conductive sheet installation, riveting and fixing, screw screwing and finished product unloading stations in sequence, eliminating the workpiece handling and repeated clamping links between different processing tables in the traditional process, and greatly reducing the process connection time.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] Example: Reference Figure 1 and Figure 2 An automatic assembly device for terminal blocks includes a base 1, a feeding component 2 and a clamping component 3. Four moving wheels 11 with braking function are fixed on the bottom surface of the base 1. A tooling plate 12 is rotatably mounted on the top surface of the base 1 in the horizontal direction. A driving component 13 for rotating the tooling plate 12 is fixed inside. A plurality of clamping seats 121 are evenly fixed on the outer edge of the top surface of the tooling plate 12. A clamping groove for the terminal block to be inserted is opened on the top surface of the clamping seat 121. The feeding assembly 2 includes a first feeding component 21, a second feeding component 22, and a third feeding component 23 fixedly mounted on the top surface of the base 1 around the tooling tray 12. The first feeding component 21 is used to automatically feed the terminal block, the second feeding component 22 is used to feed the conductive sheet, and the third feeding component 23 is used to feed the wiring screw. The clamping assembly 3 includes a first clamping component 31, a second clamping component 32, and a third clamping component 33 fixedly mounted on the base 1. The base 1 is fixedly provided with a riveting assembly 4 located between the second clamping component 32 and the third clamping component 33, and a discharge assembly 5 located between the first clamping component 31 and the third clamping component 33.

[0031] During equipment operation, the first clamping member 31 first clamps the terminal block fed by the first feeding member 21 into the clamping slot; then the driving member 13 drives the clamping base 121 to the lower moving position, and the second clamping member 32 clamps the conductive sheet onto the top surface of the terminal block, so that the limiting through hole of the conductive sheet is aligned with the limiting sleeve of the terminal block and snapped in place; then the tooling plate 12 continues to rotate, and the riveting assembly 4 bends the upper edge of the limiting sleeve outward; the tooling plate 12 continues to rotate, and the third clamping member 33 screws the wiring screw into the wiring screw hole on the terminal block; finally, the finished workpiece is automatically discharged through the discharge assembly 5.

[0032] Reference Figure 2 The base 1 has a cavity 14 for inserting the drive component 13 on its vertical side facing the support frame 61. A cover plate 15 for sealing the opening of the cavity 14 is rotatably installed. The drive component 13 is a drive motor 131 fixed in the cavity 14 and facing vertically upward. The output shaft of the drive motor 131 passes through the top surface of the base 1 and is coaxially fixedly connected to the bottom surface of the tooling plate 12.

[0033] Reference Figure 2 The first clamping member 31 includes a fixed plate 311 vertically fixed to the top surface of the base 1, an electric gripper 312 located on one side of the fixed plate 311, and a drive source 313 disposed on the fixed plate 311 to drive the electric gripper 312 to move. The drive source 313 is a drive structure composed of a horizontal electric cylinder and a vertical electric cylinder, which can drive the electric gripper 312 to slide up and down and horizontally. The second clamping member 32 is a combined clamping structure similar to the first clamping member 31. Therefore, both the first clamping member 31 and the second clamping member 32 are conventional clamping and feeding structures, and will not be described in detail here. The first feeding member 21, the second feeding member 22, and the third feeding member 23 are all vibratory feeders of different styles, and are all conventional feeding structures, and will not be described in detail here.

[0034] Reference Figure 3A vertically upward support arm 16 is fixed on the top surface of the base 1. The riveting assembly 4 includes a riveting block 41 located on one side of the support arm 16 and a vertical cylinder 42 fixed on the upper part of the support arm 16. The hydraulic cylinder of the vertical cylinder 42 is vertically downward and fixedly connected to the top surface of the riveting block 41. When the riveting block 41 moves down, it can bend and rivet the upper edge of the limiting sleeve outward. The third clamping component 33 is a screw feeder 331. The wiring bolts conveyed by the third feeding component 23 are transmitted to the end of the screw feeder 331, and then the wiring screws can be screwed into the wiring screw holes through the screw feeder 331. The screw feeder 331 is a conventional screw tightening and feeding mechanism, which will not be described in detail here.

[0035] Reference Figure 4 The discharge assembly 5 includes a discharge slide 51 slidably mounted on the top surface of the base 1, wherein the top surface of the discharge slide 51 is provided with a discharge groove 511 inclined downward in the direction away from the tooling plate 12; a fourth clamping member 52 is fixed on the base 1 to clamp the finished workpiece from the clamping slot into the discharge groove 511, wherein the structure of the fourth clamping member 52 is similar to that of the first clamping member 31, and will not be described in detail here; A collection bag 53 with its opening facing upwards and located below the opening on the lower side of the discharge chute 511 is installed on the vertical side of the base 1. After the terminal block, conductive sheet and terminal screw are assembled, the finished workpiece is clamped above the discharge slide using the fourth clamping member 52, so that the finished workpiece slides along the discharge chute 511 into the inside of the collection bag 53, thereby realizing the automatic discharge of the finished workpiece.

[0036] Reference Figure 5 and Figure 6 A support assembly 6 is provided on the vertical side of the base 1. The support assembly 6 includes a support frame 61 located on one side of the base 1. The lower edge of the support frame 61 is rotatably connected to the lower part of the vertical side of the base 1. A support frame 62 is vertically fixed on the upper edge of the support frame 61. When the support frame 61 is in the vertical upward position, the support frame 62 is in the horizontal position. A locking member 7 is provided on the bottom surface of the discharge slide 51 to limit the position of the support frame 62 in this position. A limiting member 63 is provided on the top surface of the support frame 62 at this time. When the equipment is in use, the support frame 61 is pre-adjusted to a vertical upward position and fixed by the locking piece 7. Then, the upper edge of the collection bag 53 is clamped and fixed by the limiting piece 63 to limit the installation of the collection bag 53. When the equipment is stopped for maintenance, the support frame 61 can be rotated to a horizontal position away from the base 1. At this time, the bottom surface of the support frame 62 is flush with the bottom surface of the moving wheel 11. At this time, the support frame 61 and the support block as a whole can serve as a step to raise the height of the maintenance personnel. When the cover plate 15 blocks the receiving cavity 14 and the support frame 61 is in a vertically upward position, the outer side of the cover plate 15 abuts against the inner side of the support frame 61, thereby using the support frame 61 to further limit and lock the cover plate 15.

[0037] Reference Figure 5 The limiting component 63 includes a limiting frame 631 whose one side edge is rotatably connected to the upper edge of the support frame 62, and a torsion spring (not shown in the figure) that drives the limiting frame 631 to rotate toward the support frame 62. The device can use the torsion spring to drive the limiting frame 631 to clamp the upper edge of the collection bag 53, thereby limiting and fixing the collection bag 53 when collecting finished workpieces. When it is necessary to remove the collection bag 53, the operator can apply external force to drive the limiting frame 631 to rotate away from the support frame 62, thereby releasing the limiting frame 631 from limiting the collection bag 53.

[0038] Reference Figure 5 and Figure 6 The locking component 7 includes a locking rod 71 fixed on the bottom edge of the discharge slide 51. The support frame 62 has a locking block 72 fixed on its top surface when the support frame 61 is in a vertical state. The locking block 72 has a locking notch 721. The top surface of the base 1 is provided with a power component 17, which is a power cylinder 171 fixed on the base 1. The power cylinder 171 can drive the discharge slide 51 to slide back and forth to the locked state and the unlocked state. When the discharge slide 51 is in the locked state and the support frame 61 is in the vertical upward state, the locking rod 71 slides into the locking notch 721 to lock the state of the support frame 61; when the discharge slide 51 is in the unlocked state, the locking rod 71 can slide out from the locking notch 721, at which time the restriction on the vertical support frame 61 can be released.

[0039] Reference Figure 7 and Figure 8 Two coaxial control rods 64 are slidably mounted on opposite sides of the support frame 61; the support frame 61 is provided with a support through hole 611 for the control rods 64 to pass through, and a limit baffle 641 is fixed on both ends of the control rods 64. When the support frame 61 is rotated to a horizontal position, the operator can manually control the two control rods 64 to slide towards each other until the two adjacent limit baffles 641 slide to abut against each other. At this point, they can be detached and fixed by wing screws, thereby improving the stability of the support frame 61 and the support frame 62 as a whole when used as a lifting step.

[0040] Reference Figure 9 On the vertical side of the base 1 facing the support frame 61, there are positioning rods 8 on both sides of the cover plate 15 that slide vertically. The base 1 is provided with an elastic extrusion member 9 that drives the positioning rods 8 to slide upward. A guide arc surface 81 is fixed at the upper edge of the positioning rod 8. The elastic extrusion member 9 includes a spring 91 in a compressed state, a guide block 92 fixed on the base 1, and a protruding plate 93 fixed on the outer periphery of the positioning rod 8. The protruding plate 93 is located above the guide block 92. The guide block 92 has a guide hole for the positioning rod 8 to pass through. The two ends of the spring 91 are fixedly connected to the protruding plate 93 and the guide block 92 respectively. When the support frame 61 is in a vertically upward position, the operator can manually control the two control rods 64 to slide in opposite directions. At this time, the two mutually distant limit baffles 641 can press the positioning rod 8 downward along the guide arc surface 81. At this time, the lower end face of the positioning rod 8 is flush with the bottom surface of the moving wheel 11. This is to use the positioning rod 8 to provide auxiliary support for the base 1 and improve the overall installation stability when the equipment is started and used.

[0041] The implementation principle of this application embodiment is as follows: Equipment operation status: The drive unit 13 drives the tooling plate 12 to rotate, and the first clamping member 31 clamps the terminal block into the clamping slot. The tooling plate 12 rotates to the conductive sheet feeding station, and the second clamping member 32 places the conductive sheet onto the terminal block and clamps it in place; the tooling plate 12 rotates to the next riveting station, and the vertical cylinder 42 in the riveting assembly 4 drives the riveting block 41 to bend the upper edge of the limiting sleeve on the terminal block. Then the tooling plate 12 rotates, and the third clamping member 33 screws the wiring screw into the screw hole. Finally, the fourth clamping member 52 clamps the finished product to the discharge slide 51, and the finished product slides along the slide into the collection bag 53.

[0042] When installing the collection bag 53, the support frame 61 is adjusted to a vertical position, and the discharge slide 51 is slid by the power cylinder 171, so that the locking rod 71 is engaged with the notch of the locking block 72 to complete the locking. The torsion spring of the limiting member 63 drives the limiting frame 631 to clamp the edge of the collection bag 53. When the support frame 61 is adjusted to a vertical position, the opposite sliding control rod 64 and the limiting baffle 641 press the positioning rod 8 down along the guide arc surface 81 (the lower end is flush with the moving wheel 11), which, together with the elastic extrusion member 9, assists in supporting the base 1 and improves the stability of the equipment. At the same time, when the cover plate 15 blocks the receiving cavity 14, the vertical support frame 61 can limit its movement.

[0043] Equipment maintenance status: The power cylinder 171 first drives the discharge slide 51 to slide in the opposite direction to release the lock on the vertical support frame 61. Then the support frame 61 rotates to the horizontal (the bottom surface of the support frame 62 is flush with the moving wheel 11) to form a step. The opposing sliding control rod 64 makes the two adjacent limit baffles 641 abut against each other and fix them with wing screws to improve the stability of the overall "step".
