Description

Technical Field

[0001] This invention relates to the field of charging gun manufacturing technology, specifically an automated assembly device for charging guns of new energy vehicles. Background Technology

[0002] The widespread adoption of new energy vehicles has placed higher demands on their infrastructure, especially charging equipment. As a key component connecting charging stations and vehicles, the quality and reliability of the charging gun are paramount. DC charging guns have complex internal structures, typically including a pressure plate as the core connecting component. This pressure plate has multiple slots for precisely installing conductive terminals of different specifications and functions. To facilitate terminal installation and removal, the slots for installing the terminals are often located on the side of the pressure plate, allowing for installation from the side.

[0003] Currently, the assembly of such pressure plate assemblies is mostly done manually. However, due to the large number, dense layout, and complex shape of the holes and slots on the sides of the pressure plate, the assembly process is significantly difficult, and it is not easy to clamp and position them using tools. Furthermore, because the charging gun needs to install a variety of terminals with varying lengths, diameters, and other dimensions, operators rely entirely on visual observation and touch to align and insert the terminals into the holes and slots, making it difficult to ensure that each terminal is accurately and vertically installed in its designated position. This method, which depends on personal experience and attention, easily leads to misaligned terminals, incomplete insertion, and errors such as incorrect or missing terminals, further affecting the final performance and consistency of the product. Traditional manual assembly methods are not only inefficient and costly, but also fail to guarantee the assembly accuracy and reliability of the product. Summary of the Invention

[0004] The purpose of this invention is to provide an automated assembly device for charging guns of new energy vehicles, so as to solve the problems that traditional manual assembly methods are not only inefficient and costly, but also difficult to guarantee the assembly accuracy and reliability of the products.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An automated assembly device for charging guns of new energy vehicles includes a base, an external support, a vibratory feeder, a robotic arm, a rotating disk, and a feeding conveyor belt mechanism. The external support is fixedly installed on the upper outer side of the base. Multiple sets of vibratory feeders are distributed and fixedly installed on the outside of the base. Multiple sets of robotic arms are installed on the external support, with some robotic arms corresponding to the positions of the vibratory feeders. The rotating disk is rotatably installed on the upper part of the base. One end of the feeding conveyor belt mechanism is close to the side of the rotating disk. The device is characterized in that: multiple workstations are evenly arranged on the upper side of the rotating disk, and each workstation is equipped with a clamping and positioning device. A DC terminal feeding mechanism, a terminal inner push-installation mechanism, a terminal outer push-installation mechanism, and a terminal pressing mechanism or a plug pressing mechanism are provided at the position of the base or external support corresponding to a single workstation.

[0007] The clamping and positioning device includes positioning grooves evenly arranged on a rotating disk. Rotary through-grooves are symmetrically arranged on both sides of the positioning grooves. DC terminal positioning plates are symmetrically arranged on both sides of the upper part of the rotary through-grooves. A fixing plate is fixedly arranged on the lower side of the rotating disk near the rotary through-grooves. The fixing plate is equipped with a double-sided rack that slides up and down. Gears are rotatably arranged on the fixing plate on both sides of the double-sided rack, and the gears mesh with the double-sided rack. A double-sided rack lifting cylinder is provided on the fixing plate to drive the double-sided rack to move up and down. A rotating shaft is fixedly arranged in the middle of one side of the gear. A positioning shaft is fixedly arranged on the rotating shaft. A positioning pressure block is fixedly arranged on one side of the positioning shaft. The positioning pressure blocks located on different positioning shafts are symmetrically arranged about the center line of the double-sided rack. The positioning shaft and the positioning pressure block correspond to the positions of the rotary through-grooves. When the rotating shaft rotates, it drives the positioning shaft and the positioning pressure block to rotate within the rotary through-grooves.

[0008] In a preferred embodiment, the DC terminal unloading mechanism includes an unloading block located above the positioning groove and mounted on a base or external support. The unloading block has two DC terminal unloading slots, which correspond to the rotating through slots on both sides of the positioning groove. An unloading plate is slidably mounted on the lower part of the unloading block. The unloading plate is connected to a cylinder that drives it to slide on the lower side of the unloading block. The back-and-forth sliding of the unloading plate controls the opening and closing of the slots below the DC terminal unloading slots. A DC terminal slide rail is provided between the lower side of the unloading plate and the upper side of the DC terminal positioning plate.

[0009] In a preferred embodiment, the inner side of the positioning block is provided with a stepped positioning groove, and both the inner surface of the positioning block and the inner surface of the stepped positioning groove are arc-shaped surfaces.

[0010] In a preferred embodiment, the inner terminal push-mounting mechanism is located above the rotating disk, and the outer terminal push-mounting mechanism is located outside the rotating disk. Both the inner and outer terminal push-mounting mechanisms include a slotted plate. A terminal push groove is provided on the slotted plate, and a push block is slidably disposed on the upper side of the slotted plate. A push plate is fixedly disposed on one side of the push block, and the push plate slides within the terminal push groove. A pushing cylinder is fixedly connected to one end of the slotted plate, and the output end of the pushing cylinder is connected to the push block. The pushing cylinder, together with the slotted plate, is fixedly disposed on a base or external support via a bracket. The pushing cylinder of the inner terminal push-mounting mechanism pushes the push block from inside the rotating disk to outside the rotating disk, and the pushing cylinder of the outer terminal push-mounting mechanism pushes the push block from outside the rotating disk to inside the rotating disk.

[0011] In a preferred embodiment, one end of the pusher plate extends to the outside of the pusher block.

[0012] In a preferred embodiment, both the terminal pressing mechanism and the plug pressing mechanism include a pressing cylinder fixedly mounted on a base or an external bracket. A pressing block is fixedly mounted on the lower output end of the pressing cylinder. A positioning block fixedly mounted on the base or external bracket is located below the pressing block. The positioning block has a positioning hole groove located below the pressing block. The outer contours of the positioning hole grooves of the terminal pressing mechanism and the plug pressing mechanism are respectively matched with the outer contours of the charging gun terminal and the charging gun plug.

[0013] In a preferred embodiment, a pressure rod is fixedly provided on the lower side of the pressure block of the terminal pressing mechanism, and the pressure rod corresponds to the position of the positioning hole groove of the terminal pressing mechanism.

[0014] In a preferred embodiment, one of the robotic arms is a material unloading robotic arm located near the end of the material unloading conveyor belt mechanism.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. This invention achieves a complete automated process from loading the pressure plate, installing various terminals, pressing plugs, to unloading finished products through the coordinated operation of a vibratory feeder, a robotic arm, a rotating disc, and a feeding conveyor belt, replacing the traditional inefficient manual operation mode that relies on skilled workers.

[0017] 2. The clamping and positioning device of the present invention fixes the pressure plate through the positioning groove, and uses the positioning shaft and positioning pressure block driven by the gear and rack to accurately pre-press the DC terminal into position while clamping the pressure plate. This not only provides a stable reference for subsequent installation, but also solves the problem of difficult clamping and positioning in the multi-hole groove on the side wall of the pressure plate, thus ensuring assembly accuracy.

[0018] 3. This invention employs a rotary multi-station design, enabling parallel operation of each assembly process with a fixed cycle time, significantly shortening the assembly time for a single product. Mechanized operation avoids human fatigue and errors, ensuring a high degree of stability and consistency in the quality of each product.

[0019] 4. This invention incorporates various specialized mechanisms for different terminal positions, including inward pushing, outward pushing, and vertical pressing, with rationally designed actions. In particular, the plug pressing adopts a two-step method of "guiding first and then pressing," utilizing the terminal itself for final alignment, effectively preventing interference and ensuring the reliability of the final assembly.

[0020] 5. The automated device of this invention reduces the skill requirements for operators, reduces the number of workers, thereby reducing long-term labor and management costs, and frees workers from repetitive and meticulous manual labor. Attached Figure Description

Detailed Implementation

[0034] The following embodiments will describe the present invention in detail with reference to the accompanying drawings. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0035] like Figure 1 and Figure 2As shown in the embodiment of the present invention, an automated assembly device for a new energy vehicle charging gun includes a base 1, an external support 2, a vibratory feeder 3, a robotic arm 4, a rotating disk 5, and a feeding conveyor belt mechanism 6. The external support 2 is fixedly installed on the upper outer side of the base 1. Multiple sets of vibratory feeders 3 are distributed and fixedly installed on the outside of the base 1. Multiple sets of robotic arms 4 are installed on the external support 2, with some robotic arms 4 corresponding to the positions of the vibratory feeders 3. The rotating disk 5 is rotatably installed on the upper part of the base 1. One end of the feeding conveyor belt mechanism 6 is close to the side of the rotating disk 5. The device is characterized in that: multiple workstations are evenly arranged on the upper side of the rotating disk 5, and each workstation is provided with a clamping and positioning device 7. A DC terminal feeding mechanism 8, a terminal inner push-installation mechanism 9, a terminal outer push-installation mechanism 10, and a terminal pressing mechanism 11 or a plug pressing mechanism 12 are provided at the position of the base 1 or external support 2 corresponding to a single workstation.

[0036] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, the present invention can automatically install the pressure plate 100, various terminals 300 and plug 400 in the DC charging gun of new energy vehicles. The vibratory plate 3 is used for the automatic feeding of various parts. The robot arm 4 transfers various parts to various workstations. The rotating plate 5 is used to transfer the products to be assembled to different workstations. The unloading conveyor belt mechanism 6 is used to transport the assembled products away. The clamping and positioning device 7 clamps and positions the pressure plate 100, allowing subsequent terminals 300 to be smoothly installed onto the pressure plate 100. After the terminals 300 are installed, the plug pressing mechanism 12 presses the plug 400 onto the outside of the pressure plate 100 with the terminals 300 installed. The DC terminal feeding mechanism 8 feeds the DC terminal 200 onto the clamping and positioning device 7, which clamps and positions the pressure plate 100 and the DC terminal 200. The terminal inner push mounting mechanism 9 installs the terminal 300 located on one side of the pressure plate 100 onto the pressure plate 100 from the inside, and the terminal outer push mounting mechanism 10 installs the terminal located on one side of the pressure plate 100 onto the pressure plate 100 from the outside. The terminal pressing mechanism 11 presses the terminal 300 located in the middle of the pressure plate 100 onto the pressure plate 100 from the top, and the plug pressing mechanism 12 installs the plug 400 onto the pressure plate 100 from the top.

[0037] like Figure 2 , Figure 3 and Figure 4As shown, the clamping and positioning device 7 includes positioning grooves 71 evenly distributed on the rotating disk 5. Rotary through grooves 72 are symmetrically arranged on both sides of the positioning grooves 71. DC terminal positioning plates 73 are symmetrically arranged on both sides of the upper part of the rotary through grooves 72. A fixing plate 74 is fixedly installed on the lower side of the rotating disk 5, near the rotary through grooves 72. The fixing plate 74 is provided with a double-sided rack 75 that slides up and down. Gears 76 are rotatably arranged on the fixing plate 74 on both sides of the double-sided rack 75. The gears 76 mesh with the double-sided rack 75. The fixing plate 74 is provided with... A double-sided rack lifting cylinder 77 drives the double-sided rack 75 to move up and down. A rotating shaft 78 is fixedly installed in the middle of one side of the gear 76. A positioning shaft 79 is fixedly installed on the rotating shaft 78. A positioning block 710 is fixedly installed on one side of the positioning shaft 79. The positioning blocks 710 located on different positioning shafts 79 are symmetrically arranged about the center line of the double-sided rack 75. The positioning shaft 79 and the positioning block 710 correspond to the position of the rotating through groove 72. When the rotating shaft 78 rotates, the rotating shaft 78 drives the positioning shaft 79 and the positioning block 710 to rotate in the rotating through groove 72. The clamping and positioning device 7 functions to clamp and position the pressure plate 100, and can also pre-install the DC terminal 200. Its positioning groove 71 accommodates the pressure plate 100, and the rotating through groove 72 allows the positioning block 710 to rotate. The DC terminal positioning plate 73 positions the DC terminal 200, which slides on its upper side (the DC terminal 200 has a step in the middle, which fits against the upper side of the DC terminal positioning plate 73). The double-sided rack 75 drives the gear 76 to rotate through its up-and-down movement. The double-sided rack lifting cylinder 77 controls the movement of the double-sided rack 75. The gear 76 drives the rotating shaft 78 to rotate, and the rotating shaft 78 connects the positioning shaft 79 and the positioning block 710. The positioning shaft 79 and the positioning block 710 rotate within the rotating through groove 72. The positioning shaft 79 enters the mounting groove corresponding to the DC terminal 200 on the pressure plate 100. At the same time, the positioning block 710 presses the DC terminal 200 on the DC terminal positioning plate 73 from both sides of the pressure plate 100 into the mounting groove corresponding to the DC terminal 200. At this time, the lower half of the mounting groove corresponding to the DC terminal 200 is occupied by the positioning shaft 79, and the upper half is occupied by the DC terminal 200 (at this time, the DC terminal 200 is not yet installed in place because the positioning shaft 79 occupies the lower space of the mounting groove).

[0038] like Figure 3 , Figure 4 and Figure 5As shown, the DC terminal unloading mechanism 8 includes an unloading block 81 located above the positioning groove 71 and mounted on the base 1 or external bracket 2. The unloading block 81 is provided with two DC terminal unloading slots 82, which correspond to the rotating through slots 72 on both sides of the positioning groove 71. An unloading plate 83 is slidably mounted on the lower part of the unloading block 81. The unloading plate 83 is connected to a cylinder (not shown) that drives it to slide on the lower side of the unloading block 81. The back-and-forth sliding of the unloading plate 83 controls the opening and closing of the slots below the DC terminal unloading slots 82. A DC terminal slide rail 84 is provided between the lower side of the unloading plate 83 and the upper side of the DC terminal positioning plate 73. The function of the DC terminal unloading mechanism 8 is to automatically unload the DC terminal onto the clamping and positioning device 7. Its unloading block 81 is provided with a DC terminal unloading groove 82 for guiding the DC terminal 200. The unloading plate 83 controls the opening and closing of the DC terminal unloading groove 82 by sliding. The cylinder drives the unloading plate 83 to move. The DC terminal slide 84 guides the terminal from the unloading plate 83 to the DC terminal positioning plate 73.

[0039] The positioning block 710 has a stepped positioning groove 711 on its inner side. Both the inner surface of the positioning block 710 and the inner surface of the stepped positioning groove 711 are arc-shaped surfaces. The function of the positioning block 710 is to enhance the positioning effect by engaging with the DC terminal 200 through the stepped positioning groove 711. The arc-shaped inner surfaces of the positioning block 710 and the stepped positioning groove 711 are designed to better fit the DC terminal 200, thereby improving clamping accuracy and stability.

[0040] like Figure 6 and Figure 7As shown, the inner terminal push-mount mechanism 9 is located above the rotating disk 5, and the outer terminal push-mount mechanism 10 is located outside the rotating disk 5. Both the inner terminal push-mount mechanism 9 and the outer terminal push-mount mechanism 10 include a slot plate 9101. A terminal push groove 9102 is provided on the slot plate 9101. A push block 9103 is slidably provided on the upper side of the slot plate 9101. A push plate 9104 is fixedly provided on one side of the push block 9103. The push plate 9104 slides in the terminal push groove 9102. One end of 01 is fixedly connected to a push cylinder 9105. The output end of the push cylinder 9105 is connected to the push block 9103. The push cylinder 9105, together with the slot plate 9101, is fixedly mounted on the base 1 or the external bracket 2 through a bracket. The push cylinder 9105 of the terminal inner push mounting mechanism 9 pushes the push block 9103 from the inside of the rotating disk 5 to the outside of the rotating disk 5. The push cylinder 9105 of the terminal outer push mounting mechanism 10 pushes the push block 9103 from the outside of the rotating disk 5 to the inside of the rotating disk 5. The functions of the inner terminal push-mounting mechanism 9 and the outer terminal push-mounting mechanism 10 are to push the terminal 300 located on the side of the pressure plate 100 onto the pressure plate 100 from the inside and outside, respectively. The slot plate 9101 provides a terminal push groove 9102 as a guide. The push block 9103 drives the push plate 9104 to slide, and the cylinder 9105 drives the push block 9103 to move. The terminal 300 located on the side of the pressure plate 100 is first placed in the terminal push groove 9102 by a robotic arm. The movement of the push block 9103 can drive the push plate 9104 to push the terminal located on the side of the pressure plate 100 into the pressure plate 100. The inner terminal push-mounting mechanism 9 exerts force outward from inside the rotating disk 5, while the outer terminal push-mounting mechanism 10 exerts force inward from outside the rotating disk 5. One end of the push plate 9104 extends to the outside of the push block 9103, ensuring that the push plate 9104 can effectively contact and push the terminal 300, improving installation reliability.

[0041] like Figure 8 and Figure 9As shown, both the terminal pressing mechanism 11 and the plug pressing mechanism 12 include a pressing cylinder 11121 fixedly mounted on the base 1 or the external bracket 2. A pressing block 11122 is fixedly mounted on the lower output end of the pressing cylinder 11121. A positioning block 11123 fixedly mounted on the base 1 or the external bracket 2 is provided below the pressing block 11122. The positioning block 11123 is provided with a positioning slot 11124 located below the pressing block 11122. The outer contours of the positioning slots 11124 of the terminal pressing mechanism 11 and the plug pressing mechanism 12 respectively match the outer contours of the terminal 300 and the plug 400 of the charging gun. A pressing rod 11125 is fixedly mounted on the lower side of the pressing block 11122 of the terminal pressing mechanism 11, and the pressing rod 11125 corresponds to the position of the positioning slot 11124 of the terminal pressing mechanism 11. The terminal pressing mechanism 11 and the plug pressing mechanism 12 respectively press the terminal 300 and the plug 400 onto the pressure plate 100. The pressing cylinder 11121 provides the pressing force, the pressing block 11122 directly performs the pressing action, and the positioning block 11123 fixes the position of the terminal 300 or the plug 400 through the positioning hole groove 11124. The pressing rod 11125 of the terminal pressing mechanism 11 is used to accurately press the terminal 300. The shape of the positioning hole groove 11124 matches the shape of the accessory to ensure alignment. The pressing block 11122 of the plug pressing mechanism 12 directly installs the plug 400 onto the pressure plate 100.

[0042] like Figure 2 As shown, one of the robotic arms 4 is a feeding robotic arm 41, located near the end of the feeding conveyor belt mechanism 6. The function of the feeding robotic arm 41 is to remove the assembled products from the turntable 5 and place them onto the feeding conveyor belt mechanism 6, thereby realizing an automated feeding process.

[0043] like Figures 1 to 11 As shown, the product assembly method of the present invention includes the following steps:

[0044] 1. Loading material onto the pressure plate:

[0045] The robotic arm 4 places the pressure plate 100 into the positioning groove 71 of the clamping and positioning device 7 at a certain station on the rotating disk 5. The robotic arm 4 is equipped with an electric gripper, which holds the pressure plate 100 in the two mounting grooves corresponding to the DC terminals 200. Under the guidance of the DC terminal positioning plate 73, the electric gripper can accurately place the pressure plate 100 into the positioning groove 71. The two mounting grooves corresponding to the DC terminals 200 on the pressure plate 100 are exactly aligned with the rotating through grooves 72 on both sides of the positioning groove 71. This ensures that when installing the DC terminals 200 in the next step, the DC terminals 200 can accurately enter the mounting grooves of the pressure plate 100. After the pressure plate 100 is placed, it is rotated to the next station by the rotating disk 5.

[0046] 2. Pressure plate fixing clamping and DC terminal 200 pre-installation:

[0047] (1) The DC terminal unloading mechanism 8 unloads two DC terminals 200 onto the DC terminal positioning plate 73 via the DC terminal unloading groove 82 (the step on the DC terminal 200 is located on the upper side of the DC terminal positioning plate 73).

[0048] (2) The double-sided rack lifting cylinder 77 of the clamping and positioning device 7 is activated, pushing the double-sided rack 75 downward. The double-sided rack 75 drives the two gears 76 to rotate, thereby driving the rotating shaft 78, positioning shaft 79 and positioning block 710 to rotate inward and pass between the rotating through groove 72 and the DC terminal positioning plate 73. The positioning block 710 drives the DC terminal 200 to slide inward along the DC terminal slide rail 84. As the positioning shaft 79 and positioning block 710 gradually rotate to the vertical position (the initial position is horizontal), the DC terminal 200 is pressed into the pressure plate 1 by the positioning block 710. In the mounting slot of DC terminal 200, the positioning shaft 79 also enters the mounting slot for positioning. The positioning block 710 uses its stepped positioning groove 711 to cooperate with the stepped part on the DC terminal 200 to prevent the pressure plate 100 from tilting upwards, thus completing the initial installation of the DC terminal 200 and the clamping and positioning of the pressure plate 100. The DC terminal 200 has a larger diameter than other terminals. Under the action of the positioning shaft 79 and the positioning block 710, the positioning accuracy of the pressure plate 100 is high and the stability is high, which facilitates the subsequent installation of the terminal 300 and the plug 400, and occupies little space on the upper side of the rotating disk 5. When the DC terminal 200 slides inward along the DC terminal slide rail 84, it is necessary to ensure that the lower side of the feed plate 83 is in close contact with the upper end face of the DC terminal 200 to prevent the DC terminal 200 from tilting when it is rotated and pushed by the positioning block 710, so as to ensure that the DC terminal 200 can enter the mounting slot of the pressure plate 100 better. Once completed, the component is rotated to the next workstation via rotary table 5.

[0049] 3. Install the terminal 300 inside the pressure plate 100:

[0050] The robotic arm 4 places the terminal 300 inside the pressure plate 100 into the terminal push groove 9102 of the terminal inner push mounting mechanism 9. The push cylinder 9105 of the terminal inner push mounting mechanism 9 pushes the push plate 9104 outward from the inside of the rotating disk 5, pushing the terminal 300 inside the pressure plate 100 into the pressure plate 100. The completed assembly is then transferred to the next station via the rotating disk 5.

[0051] 4. Install the terminal 300 on the outside of the pressure plate 100:

[0052] The robotic arm 4 places the terminal 300 on the outside of the pressure plate 100 into the terminal push groove 9102 of the terminal outer push mounting mechanism 10. The push cylinder 9105 of the terminal outer push mounting mechanism 10 pushes the push plate 9104 from the outside of the rotating disk 5, pushing the terminal 300 on the outside of the pressure plate 100 into the pressure plate 100. The completed assembly is then transferred to the next station via the rotating disk 5.

[0053] 5. Install the middle terminal 300 of the pressure plate 100:

[0054] After the robotic arm 4 places the terminal 300 in the middle of the pressure plate 100 into the positioning hole slot 11124 of the terminal pressing mechanism 11, the pressing cylinder 11121 drives the pressing block 11122 with the pressing rod 11125 to move downward. The pressing rod 11125 presses the terminal 300 into the pressure plate 100. The completed assembly is then rotated to the next station via the rotating disk 5.

[0055] 6. Install plug 400:

[0056] After the robotic arm 4 inserts the plug 400 into the positioning slot 11124 of the plug pressing mechanism 12 (ensuring that the terminal slots on the plug 400 correspond to each terminal), the pressing cylinder 11121 drives the pressing block 11122 with the pressing rod 11125 to move downwards a distance and stop, ensuring that the previously installed DC terminal 200 and other terminals 300 enter the corresponding empty slots of the plug 400, and that the plug 400 has not yet contacted the pressing plate 100. Then, the clamping and positioning device 7 is released. Returning to the initial state, the positioning block is no longer clamped. After the clamping and positioning device 7 is released, the pressing cylinder 11121 of the plug pressing mechanism 12 is restarted and the pressing block 11122 with the pressing rod 11125 is driven to move downward. Due to the terminal hole slots on the plug 400 and the self-guiding effect of each terminal, the plug 400 and the pressing plate 100 are finally pressed together. At the same time as the plug 400 and the pressing plate 100 are pressed together, the DC terminal 200, which was not installed in place before, is also installed in place, and the assembly is completed.
