Description

Technical Field

[0001] This invention belongs to the field of terminal block technology, specifically relating to a terminal block assembly machine and its assembly method. Background Technology

[0002] A terminal block assembly machine is a specialized piece of equipment for automating the assembly of terminal blocks. It typically integrates processes such as vibratory feeder feeding, robotic gripping, crimping, and inspection. The assembly method generally involves a vibratory feeder arranging and conveying bulk parts, such as plastic housings and metal terminals, to a designated assembly station. A high-precision pneumatic or servo robotic arm then precisely places these components into a mold, followed by pressing, riveting, or screw fastening. Finally, a vision or sensor system inspects the conductivity and appearance of the finished product. Qualified products are separated by an automatic unloading mechanism, thus replacing traditional manual assembly in a high-speed and stable manner.

[0003] However, traditional devices still have the following problems when in use: Patent application publication number CN118315898B discloses an assembly device and method for terminal blocks. The device uses a connecting piece mounting module to install connecting pieces inside a plastic component, a cap mounting module to install caps on top of the plastic component with connecting pieces, a cap riveting module to rivet the caps toward the plastic component to form a semi-finished product, a semi-finished product transfer module and a terminal pin riveting module to transfer the semi-finished product onto the terminal pins and rivet it to form a finished product, and finally a finished product discharge module to transfer the finished product, thus completing the terminal block assembly. This method avoids the problems of low efficiency and high labor intensity associated with manual assembly.

[0004] In the existing technology, when the feeding tray is working, the terminals are placed directly in the tray cavity in a disordered stacking manner and directional conveying is achieved by vibration drive. This method is prone to uncontrolled collisions between the terminals and aggravates the sliding friction and scratching between them and the inner wall of the tray and the surface of the track. This not only significantly increases the risk of wear, but also affects the appearance quality of the terminals. Therefore, we need a terminal block assembly machine and its assembly method to solve the problem of increased friction during the feeding process of terminal blocks and reduce the friction of terminal blocks. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a terminal block assembly machine and its assembly method, which has the advantage of reducing terminal block friction.

[0012] Preferably, the inner wall of the feeding box is fixedly connected to a first mounting sleeve, the outer wall of the inner side of the first mounting sleeve is fixedly connected to a first baffle, the inner wall of the first baffle is fixedly connected to a second mounting sleeve, and the inner wall of the second mounting sleeve is fixedly connected to a second baffle.

[0013] Preferably, the mounting sleeve 1 has two movable plates slidably connected inside, each located on one side of the mounting sleeve 1. The outer walls of the two movable plates on opposite sides are provided with inclined grooves and recesses. The inner walls of the recesses are fixedly connected with a return spring 2. The mounting sleeve 1 has a threaded rod 1 threadedly connected inside. The outer wall of the bottom of the threaded rod 1 is rotatably connected with an adjusting block. The outer wall of the adjusting block is in movable contact with the outer wall of the inclined groove.

[0014] Preferably, a mounting base is fixedly connected to the inner wall of the bottom of the feeding box, a return spring is fixedly connected to the lower part of the inner wall of the mounting base, a lifting plate is fixedly connected to the outer wall of the top of the return spring, the top of the lifting plate is an inclined surface, and the outer wall of the top of the lifting plate is in movable contact with the wiring terminal body.

[0015] A terminal block assembly method, implemented using a terminal block assembly machine, includes the following steps: S1: Manual loading and width adjustment: The operator loads the terminal block body into the feeding tray and rotates the threaded rod to drive the movable plate to extend. The channel width is adjusted according to the size of the terminal block body to prevent the terminal block body from tilting when moving.

S4: Lifting and automatic sliding in: The pushed terminal block body presses against the lifting plate, causing the original terminal block body to rise one layer, and the top terminal block body automatically slides into the track groove of the rotating shell along the inclined surface at the top of the lifting plate. S5: Intermittent discharge and rhythmic feeding: The rotating shell drives the terminal body in the track groove to rotate. When the track groove is aligned with the discharge port, the terminal body slides out sequentially at fixed time intervals, achieving rhythmic synchronization with subsequent assembly processes.

[0016] Compared with the prior art, the beneficial effects of the present invention are: After the terminal block enters the track groove, it rotates as the rotating shell drives the terminal block to rotate. When the track groove aligns with the discharge port, the terminal block slides out of the discharge port. The partition plate separates the top of the rotating shell into multiple independent track grooves, which physically isolates the terminal block during the conveying process. This avoids scratches on the surface coating or wear on the plastic shell caused by mutual collision, squeezing and friction between the terminal blocks in traditional vibratory feeders or open turntables.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1 to 12 This invention provides a terminal block assembly machine and its assembly method: it includes a feeding tray 1, an outlet 11 on the outer wall of one side of the feeding tray 1, a rotating shell 21 rotatably connected inside the feeding tray 1, a partition plate 2 fixedly connected to the outer wall of the top of the rotating shell 21, a connecting frame 24 fixedly connected to the inner wall of the rotating shell 21, a track groove formed between the two partition plates 2, a motor 22 fixedly connected to the lower part inside the feeding tray 1, a gear 23 fixedly connected to the output end of the motor 22, and the outer wall of the gear 23 meshing with the inner ring wall of the connecting frame 24.

[0021] After the terminal block body 7 enters the track groove, it is driven to rotate by the rotating shell 21. When the track groove is aligned with the discharge port 11, the terminal block body 7 slides out from the discharge port 11. The partition plate 2 divides the top of the rotating shell 21 into multiple independent track grooves, so that the terminal block body 7 is physically isolated during the conveying process. This avoids scratches on the surface coating or wear on the plastic shell caused by mutual collision, squeezing and friction between the terminal blocks 7 in traditional vibratory feeders or open turntables.

[0022] In Example 2, based on Example 1, a second motor 4 is fixedly connected to the lower center of the inside of the feeding tray 1. A rotating shaft 41 is fixedly connected to the output end of the second motor 4. A feeding box 6 is rotatably connected through the top outer wall of the rotating shaft 41. A second gear 43 is fixedly connected to the top outer wall of the rotating shaft 41. A support plate 46 is fixedly connected to the lower part of the inside of the feeding box 6. A threaded rod 45 is rotatably connected inside the support plate 46. A movable push rod 47 is threadedly connected to the outer wall of the threaded rod 45. A limit groove 48 is opened at the lower part of the inner wall of the feeding box 6. A third gear 44 is slidably connected to the outer wall of one end of the threaded rod 45. The outer wall of the movable push rod 47 is meshed with the outer wall of the gear 43. The outer wall of the bottom of the movable push rod 47 is fixedly connected to the slide rod 49. The outer wall of the slide rod 49 is slidably connected to the inside of the limiting groove 48. The outer wall of one side of the movable push rod 47 is fixedly connected to the push plate 42. The inner wall of one side of the push plate 42 is in movable contact with the outer wall of the other end of the threaded rod 45. The inner wall of the bottom of the feeding box 6 is fixedly connected to the mounting base 5. The lower part of the inner wall of the mounting base 5 is fixedly connected to the return spring 52. The outer wall of the top of the return spring 52 is fixedly connected to the lifting plate 51. The top of the lifting plate 51 is an inclined surface. The outer wall of the top of the lifting plate 51 is in movable contact with the terminal body 7.

[0023] When the push plate 42 moves forward, it pushes the terminal block body 7 to move, pushing the terminal block body 7 from the cavity between the first baffle 9 and the second baffle 91 to the cavity between the first baffle 9 and the feeding box 6. By pushing the terminal block body 7 through the push plate 42, the friction of the terminal block body 7 vibrating and shifting inside the feeding tray 1 is reduced, thus ensuring the appearance quality of the product. The top of the lifting plate 51 is inclined outward. When a terminal block 7 is added above the lifting plate 51, the uppermost terminal block 7 is moved out of the cavity and placed above the rotating shell 21. Using the inclined force, the terminal block 7 slides into the track groove, completing the automatic feeding of the terminal block 7. Through the linkage mechanism of pushing the terminal block 7 in and moving the old terminal block 7 upward, the automatic lifting and orderly transfer of the terminal block 7 is realized. There is no need for an independent lifting mechanism. The inclined guide makes the uppermost terminal block 7 automatically slide into the track groove, eliminating the need for a robot or pneumatic device and simplifying the structure.

[0024] In Example 3, based on Example 2, the outer wall of the threaded rod 45 is provided with a sliding groove 81, an insertion hole 82, and an insertion hole 84. The inner wall of the gear 44 is fixedly connected to a limiting plate 8. The outer wall of the limiting plate 8 is slidably connected to the inside of the sliding groove 81. A circular hole is provided on the limiting plate 8. A threaded rod 83 is connected inside the circular hole. The outer wall of the threaded rod 83 is threadedly connected to the inside of the insertion hole 84. The outer wall of the threaded rod 83 is threadedly connected to the inside of the circular hole.

[0025] By changing the number of gears 3 44 involved in the work, the number of terminal block bodies 7 pushed at the same time can be adjusted, thereby affecting the arrangement spacing of the terminal block bodies 7 on the subsequent conveyor belt. When it is necessary to increase the spacing of the terminal block bodies 7 to leave more space for subsequent visual inspection, robotic gripping or manual operation, this can be achieved by reducing the drive of gears 3 44. This adjustable spacing design enhances the equipment's adaptability to different assembly processes.

[0026] In Example 4, based on Example 3, the inner wall of the feeding box 6 is fixedly connected to the mounting sleeve 1 3, the outer wall of the inner side of the mounting sleeve 1 3 is fixedly connected to the baffle 1 9, the outer wall of the inner side of the baffle 1 9 is fixedly connected to the mounting sleeve 2 92, the outer wall of the inner side of the mounting sleeve 2 92 is fixedly connected to the baffle 2 91, the inside of the mounting sleeve 1 3 is slidably connected to the movable plate 31, there are two movable plates 31 located on both sides inside the mounting sleeve 1 3, the outer wall of the opposite side of the two movable plates 31 is provided with an inclined groove 34, the outer wall of the opposite side of the two movable plates 31 is provided with a groove 36, the inner wall of the groove 36 is fixedly connected to the return spring 2 35, the inside of the mounting sleeve 1 3 is threadedly connected to the threaded rod 1 32, the outer wall of the bottom of the threaded rod 1 32 is rotatably connected to the adjusting block 33, the outer wall of the adjusting block 33 is in movable contact with the outer wall of the inclined groove 34.

[0027] The movable plate 31 contacts the terminal block body 7 to prevent the terminal block body 7 from tilting during movement. The movable plate 31 can be adjusted according to the size of the terminal block body 7. The movable plate 31 can effectively prevent the terminal block body 7 from tilting or deflecting to the left or right, ensuring that the terminal block body 7 always moves along the predetermined trajectory in the correct posture. This anti-tilting design improves the stability of feeding.

[0028] Example 5: A terminal block assembly method, implemented based on a terminal block assembly machine from Examples 1 to 4, comprising the following steps: S1: Manual loading and width adjustment: The worker loads the terminal block body 7 into the feeding tray (1) and rotates the threaded rod 32 to drive the movable plate 31 to extend. The width of the channel is adjusted according to the size of the terminal block body 7 to prevent the terminal block body 7 from tilting when it moves. By rotating the threaded rod to drive the movable plate 31 to extend, the width of the channel can be infinitely adjusted, enabling the same equipment to be compatible with various specifications of terminal block bodies 7, enhancing the equipment's versatility and flexible production capabilities. At the same time, the movable plate 31 provides lateral restraint to the terminal block body 7, effectively preventing the terminal block body 7 from tilting or deflecting to the left or right during movement, ensuring that the terminal block body 7 always moves along the predetermined trajectory in the correct posture, providing a precise positional basis for subsequent processes.

[0029] S2: Turntable rotation and track separation: Start motor 22 drives rotating shell 21 to rotate. The partition plate on the top of rotating shell 21 physically isolates multiple terminal bodies 7 in independent track grooves to avoid mutual collision and friction. The top of the rotating shell 21 is divided into multiple independent track slots by the partition plate 2, so that the terminal body 7 is physically isolated during the conveying process. This avoids scratches on the surface coating or wear on the plastic shell caused by mutual collision, squeezing and friction between the terminal bodies 7 in the traditional vibratory feeder, thus ensuring the appearance quality of the product. At the same time, the multi-track design realizes multi-channel parallel conveying and improves the feeding efficiency.

[0030] S3: Pushing and feeding material and lifting the upper layer: Motor 2 4 drives the push plate 42 to reciprocate. While pushing the bottom terminal body 7 forward, the upper surface of the push plate 42 lifts the upper terminal body 7 to prevent it from falling and jamming. While pushing the bottom terminal block 7, the push plate 42 temporarily supports the stacked terminal block 7 on its upper surface. This prevents the upper terminal block 7 from falling freely and crashing into the pushing channel after the bottom terminal block 7 is pushed away, which would cause the moving push rod 47 to fail to reset properly or even become mechanically jammed. The push plate 42 completes both pushing and lifting functions in the same action cycle. No additional sensors, cylinders or control logic are required, which simplifies the control system, reduces the risk of failure, and ensures the continuous and smooth operation of the mechanism.

[0031] S4: Lifting and automatic sliding in: The pushed terminal block body 7 presses against the lifting plate 51, causing the original terminal block body 7 to rise one layer, and the uppermost terminal block body 7 automatically slides into the track groove of the rotating shell 21 along the inclined surface of the top of the lifting plate 51. Through the linkage mechanism of pushing in the new terminal block body 7 and moving the old terminal block body 7 upward, the automatic lifting and orderly transfer of the terminal block body 7 is realized. There is no need for an independent lifting mechanism. The inclined guide at the top of the lifting plate 51 allows the uppermost terminal block body 7 to automatically slide into the track groove, eliminating the need for a robotic gripper or pneumatic blowing device, simplifying the structure and reducing manufacturing costs. At the same time, the terminal block bodies 7 slide and lift gradually, reducing hard collision damage and further ensuring the product's appearance quality.

[0032] S5: Intermittent discharge and rhythmic feeding: The rotating shell 21 drives the terminal body 7 in the track groove to rotate. When the track groove is aligned with the discharge port 11, the terminal body 7 slides out sequentially at fixed time intervals, achieving rhythmic synchronization with subsequent assembly processes.

[0033] By controlling the alignment of the partition plate 2 with the discharge port 11, the terminal body 7 slides out sequentially at fixed time intervals and in fixed quantities, realizing a rhythmic feeding method. This intermittent feeding is synchronized with subsequent assembly processes such as crimping, screw tightening, and testing, avoiding material accumulation due to excessive feeding or equipment idling due to excessive feeding. It achieves precise rhythm matching between upstream and downstream processes, improving the overall operating efficiency and stability of the line.

[0034] The working principle and usage process of this invention are as follows: During operation, firstly, the operator places the terminal block body 7 into the cavity between baffle 1 9 and baffle 2 91. After the feeding tray 1 is filled with the terminal block body 7, the motors 1 22 and 2 4 inside the feeding tray 1 are started simultaneously. The movement of motor 1 22 drives gear 1 23 to rotate. Due to the meshing connection between gear 1 23 and connecting frame 24, the rotation of gear 1 23 causes the connecting frame 24 to drive the rotating shell 21 to rotate. Furthermore, due to the fixed connection between the rotating shell 21 and the partition plate 2, the rotating shell 21 rotates simultaneously... This will cause the partition plate 2 to move accordingly. The partition plate 2 separates the top of the rotating shell 21 into multiple track grooves. After the terminal body 7 enters the track groove, when the rotating shell 21 drives the terminal body 7 to rotate, when the track groove is aligned with the discharge port 11, the terminal body 7 slides out from the discharge port 11. The partition plate 2 separates the top of the rotating shell 21 into multiple independent track grooves, so that the terminal body 7 is physically isolated during the conveying process, avoiding scratches on the surface coating or wear on the plastic shell caused by mutual collision, squeezing and friction between the terminal bodies 7 in traditional vibratory feeders or open turntables.

[0035] This invention ensures that the terminal body 7 slides out only after the partition plate 2 is aligned with the discharge port 11, thus creating a regular, intermittent feeding speed on the terminal body 7. By controlling the alignment timing between the partition plate 2 and the discharge port 11, the terminal body 7 is not continuously ejected, but rather fed out sequentially at fixed time intervals and in fixed quantities. This rhythmic feeding method is synchronized with subsequent assembly processes such as crimping, screw tightening, and inspection, avoiding material accumulation due to excessively fast feeding or equipment idling due to excessively slow feeding, and achieving precise rhythm matching between upstream and downstream processes.

[0036] This invention utilizes the movement of motor 4. Due to the fixed connection between motor 4 and rotating shaft 41, the rotation of rotating shaft 41 causes gear 43 to rotate accordingly. Because of the meshing connection between gear 43 and gear 44, the rotation of gear 43 drives multiple gears 44 to rotate. Since gear 44 is connected to threaded rod 45 via threaded insert 83, the movement of gear 44 causes threaded rod 45 to rotate. Furthermore, through the threaded connection between threaded rod 45 and movable push rod 47, the threaded rod 45 rotates... When in motion, the movable push rod 47 drives the slide rod 49 to move back and forth along the direction of the limiting groove 48. Due to the fixed connection between the movable push rod 47 and the push plate 42, when the movable push rod 47 moves, it pushes the push plate 42 to move accordingly. When the push plate 42 moves forward, it pushes the terminal body 7 to move, pushing the terminal body 7 from the cavity between the first baffle 9 and the second baffle 91 to the cavity between the first baffle 9 and the feeding box 6. By pushing the terminal body 7 with the push plate 42, the friction of the terminal body 7 vibrating and shifting inside the feeding tray 1 is reduced, ensuring the appearance quality of the product.

[0037] It should be noted that the material is fed once every one revolution of the rotating shell 21, which avoids the motor 2 4 from working continuously and accumulating the terminal block body 7 inside the track groove.

[0038] By using the push plate 42, the upper surface of the push plate 42 simultaneously acts as a temporary support platform when pushing the bottom terminal body 7 forward, lifting the terminal body 7 that was originally stacked on top. This prevents the upper terminal body 7 from falling freely and crashing into the push channel after the bottom terminal body 7 is pushed away, which could cause the moving push rod 47 to fail to reset properly or even become mechanically jammed. The lifting function of the push plate 42 ensures that there are no obstructions in the channel when the moving push rod 47 returns, ensuring the continuous and smooth operation of the mechanism. The push plate 42 completes both pushing and lifting functions in the same action cycle, without the need for additional sensors, cylinders, or control logic to control them separately, reducing the complexity and failure risk of the control system.

[0039] In this invention, the side of the lifting plate 51 that contacts the terminal body 7 is inclined. Before the terminal body 7 presses against the lifting plate 51, the terminal body 7 first contacts the bottom of the terminal body 7 above the lifting plate 51. After the terminal body 7 has moved above the lifting plate 51, the original terminal body 7 on the lifting plate 51 can be pushed upwards. Under the pushing action of the pushing plate 42, the terminal body 7 is pressed against the lifting plate 51. The lifting plate 51 is subjected to the pressing force, which presses the return spring 52 into the interior of the mounting base 5, so that the terminal body 7 is completely moved above the lifting plate 51, and the original terminal body 7 on the lifting plate 51 is removed. The terminal block body 7 is pushed upward. Since the top of the lifting plate 51 is inclined outward, when an additional terminal block body 7 is added above the lifting plate 51, the uppermost terminal block body 7 is moved out of the cavity and placed above the rotating shell 21. Using the inclined force, the terminal block body 7 slides into the track groove, completing the automatic feeding of the terminal block body 7. Through the linkage mechanism of pushing the terminal block body 7 in and moving the old terminal block body 7 upward, the automatic lifting and orderly transfer of the terminal block body 7 is realized. There is no need for an independent lifting mechanism. The inclined guide makes the uppermost terminal automatically slide into the track groove, eliminating the need for a robot or pneumatic device and simplifying the structure.

[0040] It should be noted that after the terminal block 7 at the top of the lifting plate 51 enters the track groove, the lifting plate 51 is pushed upward by the reset spring 52 to return to its original position.

[0041] This invention involves an operator rotating the threaded insert 83 to disengage it from the second insertion hole 84, thereby releasing the threaded insert 83 from fixing the limiting plate 8. Then, the third gear 44 is pushed, causing the limiting plate 8 to slide on the sliding groove 81. When the limiting plate 8 contacts the other end of the sliding groove 81, the first insertion hole 82 aligns with the circular hole on the limiting plate 8. The threaded insert 83 is then screwed back into the first insertion hole 82 to fix the limiting plate 8, releasing the meshing connection between the third gear 44 and the second gear 43. At this point, when the second gear 43 rotates again, it cannot drive the third gear 44, which is not meshed with the second gear 43, thus changing the feeding speed of the terminal block body 7. By changing the number of gears 3 44 involved in the work, the number of terminal block bodies 7 pushed at the same time can be adjusted, thereby affecting the arrangement spacing of the terminal block bodies 7 on the subsequent conveyor belt. When it is necessary to increase the spacing of the terminal block bodies 7 to leave more space for subsequent visual inspection, robotic gripping or manual operation, this can be achieved by reducing the drive of gears 3 44. This adjustable spacing design enhances the equipment's adaptability to different assembly processes.

[0042] This invention involves an operator rotating a threaded rod 32. Due to the threaded connection between the threaded rod 32 and the mounting sleeve 3, and the internal rotational connection between the threaded rod 32 and the adjusting block 33, the threaded rod 32 moves upward within the mounting sleeve 3, causing the adjusting block 33 to move upward as well. Because of the movable contact between the adjusting block 33 and the inclined groove 34, the moving block 33 pushes the movable plate 31 out of the mounting sleeve 3, increasing the width of the mounting sleeve 3 and allowing the movable plate 31 to contact the terminal body 7. This prevents the terminal body 7 from tilting during movement. Furthermore, the movable plate 31 can be adjusted according to the size of the terminal body 7. The movable plate 31 effectively prevents the terminal body 7 from tilting left or right or deflecting, ensuring that the terminal body 7 always moves along a predetermined trajectory in the correct posture. This anti-tilting design improves the stability of the feeding process.

[0043] When the adjusting block 33 moves downward, the movable plate 31 is pulled back to its original position by the action of the reset spring 35.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
