Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0025] Combination Figures 1 to 3 As shown, this utility model discloses an automatic charger assembly machine. This machine can automatically assemble the charger's bottom shell, PCB board, and top cover, and performs optical inspection, electrical testing, and laser engraving on the assembled semi-finished products before finally unloading them. This embodiment mainly describes the automatic assembly process of the bottom shell, PCB board, and top cover. The optical inspection, electrical testing, and laser engraving processes can all be implemented using relatively mature products in the prior art, and their structure and working principle will not be described in detail in this embodiment. Specifically, in conjunction with... Figure 1 , Figure 2 As shown, the automatic charger assembly machine of this utility model includes a PCB material conveying line 10, a bottom shell assembly mechanism 20, a PCB assembly mechanism 30, a top cover assembly mechanism 40, and a fixture circulation line 50. The bottom shell assembly mechanism 20 and the top cover assembly mechanism 40 are arranged side by side, and the fixture circulation line 50 is located on the opposite side of the bottom shell assembly mechanism 20 and the top cover assembly mechanism 40. The bottom shell assembly mechanism 20 is used to transfer the bottom shell to be assembled onto the fixture 501 of the fixture circulation line 50. The fixture circulation line 50 adopts chain drive and has six working positions and a total of 12 fixtures in this embodiment, which can drive the fixtures to rotate. Further, one end of the PCB material conveying line 10 is used to receive the PCB board to be assembled, and the other end extends between the bottom shell assembly mechanism 20 and the fixture circulation line 50. The PCB assembly mechanism 30 is located on one side of the fixture circulation line 50, and the PCB board on the PCB material conveying line 10 is assembled into the bottom shell of the fixture through the PCB assembly mechanism 30. Continue to refer to Figure 2 As shown, the upper cover assembly mechanism 40 is located at the end of the PCB incoming material conveying line 10. The upper cover is assembled at the bottom shell opening of the fixture through the upper cover assembly mechanism 40.

[0026] The automatic charger assembly machine of this utility model, through the above-described structure, can sequentially realize the feeding of the bottom shell, the assembly of the PCB board, and the feeding and assembly of the top cover. The assembly process is as follows: First, the PCB board to be assembled is placed on the PCB feeding conveyor line 10. The bottom shell assembly mechanism 20 transfers the bottom shell to be assembled into the fixture of the fixture circulation line 50. This fixture rotates under the drive of the fixture circulation line 50, and its rotation direction is consistent with the running direction of the PCB feeding conveyor line 10. Then, the PCB assembly mechanism 30 assembles the PCB board from the PCB feeding conveyor line 10 into the bottom shell. Finally, the top cover assembly mechanism 40 places the top cover over the opening of the bottom shell, completing the assembly process. The entire assembly process is fully automated. Therefore, the automatic charger assembly machine of this utility model can realize the automatic assembly of the charger bottom shell, top cover, and PCB board. It has high production efficiency, stable product quality, good product consistency, and low labor intensity for workers, enabling automated mass production of chargers.

[0027] Regarding the bottom shell assembly mechanism 20, refer to... Figure 2 , Figure 3 As shown, the bottom shell assembly mechanism 20 includes a bottom shell tray 201, a bottom shell loading robot 202, a bottom shell flipping device 203, and a bottom shell moving robot 204. The bottom shell tray 201 and the bottom shell flipping device 203 are located on opposite sides of the PCB incoming material conveyor line 10. The bottom shell loading robot 202 is located above the bottom shell tray 201 and transfers the bottom shells to be assembled in the tray to the bottom shell flipping device 203. The bottom shell moving robot 204 is located above the bottom shell flipping device 203 and the fixture circulation line 50. After the bottom shell is flipped by the bottom shell flipping device 203, the bottom shell moving robot 204 transfers the flipped bottom shell into the fixture of the fixture circulation line 50.

[0028] Regarding the PCB assembly mechanism 30, refer to Figure 2 , Figure 3 As shown, the PCB assembly mechanism 30 includes a PCB moving robot 301, a PCB flipping device 302, and a PCB assembly robot 303. The PCB assembly robot 303 and the PCB moving robot 301 are located behind the bottom shell moving robot 204. The PCB flipping device 302 is located between the PCB assembly robot 303 and the PCB moving robot 301. The PCB moving robot 301 transfers the PCB board on the PCB incoming material conveyor line 10 to the PCB flipping device 302. After the PCB board is flipped by the PCB flipping device 302, the PCB assembly robot 303 inserts the PCB board into the bottom shell.

[0029] Furthermore, regarding the aforementioned upper cover assembly mechanism 40, refer to... Figure 2 , Figure 3 As shown, the upper cover assembly mechanism 40 includes an upper cover tray 401, an upper cover loading robot 402, an upper cover positioning fixture 403, and an upper cover moving robot 404. The upper cover loading robot 402 is located above the upper cover tray 401 and transfers the upper cover into the upper cover positioning fixture 403. The upper cover moving robot 404 is located above the upper cover positioning fixture 403 and the fixture circulation line 50 and installs the upper cover in the upper cover positioning fixture 403 into the bottom shell opening.

[0030] Based on the above description, we will now explain the working principle of this utility model in detail: First, PCB boards to be assembled are arranged side by side on the PCB incoming material conveyor line 10. Bottom shells to be assembled are placed in the bottom shell tray 201, and top covers to be assembled are placed in the top cover tray 401. The bottom shell loading robot 202 transfers the bottom shells from the bottom shell tray 201 to the bottom shell flipping device 203. The bottom shell flipping device 203 rotates the bottom shells 90° to a vertical position with their openings facing upwards. Then, the bottom shell moving robot 204 transfers the bottom shells with their openings facing upwards into the fixture of the fixture circulation line 50, which in turn moves the fixture. Further, the PCB moving robot 301 transfers the PCB boards from the PCB incoming material conveyor line 10 to the PCB flipping device 302, rotating them 90° to a vertical position. Then, the PCB assembly robot 303 inserts the vertically positioned PCB boards into the bottom shells through their openings, completing the assembly of the PCB boards. Subsequently, the fixture circulation line 50 continues to rotate, and the top cover loading robot 402 transfers the top cover from the top cover tray 401 to the top cover positioning fixture 403, improving the positioning accuracy of the top cover. The top cover moving robot 404 then transfers the top cover from the positioning fixture to the opening of the bottom shell on the fixture circulation line 50, thus completing the automatic assembly of the top cover. The above process has fully illustrated the automatic assembly process of the bottom shell, PCB board, and top cover.

[0031] It should be noted that in the above embodiments, both the bottom shell loading robot 202 and the top cover loading robot 402 adopt XYZ three-axis motion modules. These XYZ three-axis motion modules utilize existing, mature technologies such as motors, slide rails, and sliders to achieve reciprocating motion. Since the motion principle of this structure is very common in existing technologies, those skilled in the art will not encounter any difficulties in understanding its application; therefore, its structure will not be described in detail in this embodiment. Similarly, the bottom shell moving robot 204, the PCB assembly robot 303, the PCB moving robot 301, and the top cover moving robot 404 all adopt a lead screw module structure, enabling reciprocating translation between the PCB material conveying line 10 and the fixture circulation line 50. A Z-axis lead screw module is also provided in the vertical direction to achieve reciprocating motion in the vertical direction. This type of lead screw module is a very mature technology in existing technologies; therefore, the specific structure of the above-mentioned robots will not be described in detail in this embodiment. The main difference lies in the output structure of the Z-axis module of each robotic arm, which differs slightly to achieve its corresponding function. For example, the bottom shell moving robotic arm 204 has a combination of a rotary motor and a finger cylinder on the output end of its Z-axis module to grip and rotate the bottom shell. The bottom shell is gripped by the finger cylinder, rotated horizontally by 90°, and then placed into the fixture. The top cover moving robotic arm 404 only needs to grip the top cover and achieve translation in the horizontal and vertical directions, so only a finger cylinder is needed on its Z-axis. The structures of the PCB moving robotic arm 301 and the PCB assembly robotic arm 303 are similar, and will not be described in detail in this embodiment.

[0032] In addition, the upper cover assembly mechanism 40 also includes an upper cover pressing device 405, which is located behind the upper cover moving robot 404 to press the upper cover tightly onto the bottom shell opening. The upper cover pressing device 405 is located above the fixture circulation line 50. After the upper cover assembly mechanism 40 completes the assembly of the upper cover, pressure is applied to tighten the upper cover onto the bottom shell opening. In this embodiment, the upper cover pressing device 405 includes a cylinder and a pressing block fixed to the top of the cylinder rod. The cylinder drives the pressing block to achieve the pressing of the upper cover.

[0033] Regarding the bottom shell flipping device 203, refer to Figure 3As shown, this utility model provides a specific embodiment in which the bottom shell flipping device 203 includes a first flipping cylinder 2031, a first fixing plate 2032, a first finger cylinder 2033, a first positioning cylinder 2034, and a first positioning plate 2035. The first finger cylinder 2033 is fixedly mounted on the first fixing plate 2032, and the first fixing plate 2032 is mounted on the motor shaft of the first flipping cylinder 2031. The first flipping cylinder 2031 drives the first finger cylinder to rotate, thereby flipping the horizontal bottom shell 206 to a vertical state to ensure that the opening of the bottom shell faces upward. Further, the first positioning cylinder 2034 is fixedly mounted below the first fixing plate 2032. One end of the first positioning plate 2035 is fixed to the top of the cylinder rod of the first positioning cylinder 2034, and the other end extends to the top of the first fixing plate 2032. A space for positioning the bottom shell is formed between the first positioning plate 2035 and the gripper of the first finger cylinder 2033. Therefore, after the bottom shell 206 is placed in the positioning space, the first positioning cylinder 2034 drives the first positioning plate 2035 to retract, so that the bottom end of the bottom shell is tightly attached to the bottom of the gripper. This ensures that each bottom shell is in the same position before flipping, improving the positioning accuracy and enhancing the precision of the bottom shell moving robot 204 in transferring the bottom shell into the fixture. Subsequently, the first flipping cylinder 2031 drives the first fixing plate 2032 and the first finger cylinder 2033 to flip 90°, so that the bottom shell is in a vertical position with the opening of the bottom shell 206 facing upwards. Then, the moving robot transfers the bottom shell into the fixture.

[0034] Furthermore, regarding the PCB flipping device 302, refer to... Figure 4As shown, this utility model also provides a specific embodiment, wherein the PCB flipping device 302 includes a second flipping cylinder 3021, a second finger cylinder 3022, a positioning fixture 3023, a second positioning cylinder 3024, and a second positioning plate 3025; the second finger cylinder 3022 is fixedly installed on the cylinder rod of the second flipping cylinder 3021, the positioning fixture 3023 is located on one side of the second finger cylinder 3022, and the PCB moving robot 301 transfers the PCB board 304 into the positioning fixture 3023; the second positioning cylinder 3024 is located on the other side of the positioning fixture 3023, and the second positioning plate 3025 is connected to the top of the cylinder rod of the second positioning cylinder 3024, and a space for positioning the PCB board 304 is formed between the second positioning plate 3025 and the gripper of the second finger cylinder 3022. Furthermore, the PCB flipping device 302 also includes a positioning base plate 3026, a positioning slide rail 3027, and a positioning slider 3028; the second positioning cylinder 3024, the positioning slide rail 3027, and the positioning fixture 3023 are all fixed on the positioning base plate 3026, and the positioning slider 3028 is slidably disposed on the positioning slide rail 3027. One end of the positioning slider 3028 is connected to the cylinder rod of the second positioning cylinder 3024, and the other end is fixedly connected to the second positioning plate 3025.

[0035] With this structure, after the PCB moving robot 301 transfers the PCB board into the positioning fixture 3023, the second positioning cylinder 3024 drives the positioning slider 3028 to move along the positioning slide rail 3027, causing the second positioning plate 3025 to move towards the positioning fixture 3023, pushing the bottom end of the PCB board to contact the bottom of the gripper of the second finger cylinder 3022. Thereafter, the gripper of the second finger cylinder 3022 clamps the PCB board. After the second flipping cylinder 3021 drives the second finger cylinder 3022 to flip 90°, the PCB board is brought into a vertical position so that the PCB assembly robot 303 can grip the PCB board to achieve its assembly.

[0036] In the above embodiments, combined with Figure 2 , Figure 6 As shown, the automatic charger assembly machine also includes a semi-finished product transfer device 60, located at the end of the fixture circulation line 50, for unloading the bottom shell assembled with the PCB board and top cover. Specifically, in this embodiment, the semi-finished product transfer device 60 mainly includes a finger cylinder for clamping the bottom shell, a rotary motor for rotating the finger cylinder, and a power module for reciprocating translation of the entire device. Furthermore, the assembled semi-finished product needs to undergo optical and electrical performance testing; therefore, in the above embodiment, combined with… Figure 1 and Figure 6As shown, the automatic charger assembly machine also includes an optical inspection mechanism 70, an electrical testing mechanism 80, a laser engraving sorting mechanism 90 / material conveyor line 100, and an assembly conveyor belt 200. The assembly conveyor belt 200 is located at the top of the machine. The semi-finished product transfer device 60 is slidably mounted on a movable slide rail 601. The optical inspection mechanism 70 is located on one side of the movable slide rail. The semi-finished product transfer device 60 drives the bottom shell, which has been assembled with the PCB board and the top cover, to move below the optical inspection mechanism 70 for inspection. The electrical testing mechanism 80, the laser engraving sorting mechanism 90, and the material conveyor line 100 are sequentially arranged at the end of the movable slide rail to perform electrical performance testing, automatic laser engraving, and sorting and unloading in sequence. This function can utilize mature technologies in the prior art. Therefore, the specific structure of the electrical testing mechanism 80, the laser engraving sorting mechanism 90, and the material conveyor line 100 will not be described in detail in this embodiment.

[0037] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
