Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to an oiling device for a pure copper plug for an electric vehicle charging plug. Background Technology

[0002] The pure copper plug for charging plugs is the interface connecting electric vehicles and charging equipment. It needs to meet requirements such as high power transmission, safety, reliability, and durability. Pure copper has good electrical conductivity, thermal conductivity, and mechanical properties, making it an ideal material for manufacturing pure copper plugs for charging plugs. Currently, the manufacturing process for pure copper plugs for charging plugs involves using a Swiss-type lathe to process pure copper rods into the finished structure in one go, and then electroplating the surface to obtain the finished product. Pure copper plugs for charging plugs have similar shapes and various structural types. The charging port needs to be frequently plugged and unplugged during use. In order to ensure the stability of the electrical appliance and protect the charging port from oxidation, corrosion, water, and sealing, it is necessary to apply oil to its interior.

[0003] Currently, the pure copper plugs in charging plugs are mainly coated with oil manually or by robots using contact brushes. However, due to the complex structure and small size of the plugs, manual oiling is difficult to accurately cover the dead corners of the cavity, resulting in low efficiency and poor consistency. Although robotic oiling improves efficiency, the contact brushes are prone to breakage and residue, which contaminates the inside of the pure copper plugs in the charging plugs and affects the reliability of conductivity. The above oiling methods cannot simultaneously meet the requirements of penetration into narrow gaps and no residue, resulting in the pure copper plugs in the charging plugs failing to meet the standards for anti-oxidation and sealing performance.

[0004] Therefore, it is of great importance to design an oiling device for the pure copper plug of electric vehicle charging plugs to solve the above-mentioned defects. Utility Model Content

The multiple sets of contoured acupoints allow for the simultaneous completion of positioning and oiling operations for multiple charging plug products when the placement turntable rotates and switches positions. Starting the turntable motor causes the placement turntable to rotate, using a small... A pneumatic press drives a pressure tank to dispense oil into the dispensing valve. Under pressure, the dispensing valve dispenses an appropriate amount of oil. During oiling, the linear module drives the lifting frame to descend, pausing the oiling needle at the oiling position on the charging plug. The dispensing valve opens to supply oil and simultaneously starts the oiling motor, which drives the oiling needle to rotate via a synchronous pulley set. The oiling needle is used to apply oil to the inside of the charging plug.

In this utility model, through the design of the material handling mechanism, after the charging plug product is coated with oil and rotated to the position of the material handling mechanism, the first cylinder is activated to extend, and the linkage rod pushes the rotating shaft to drive the second cylinder to rotate. Then, the second cylinder drives the gripper cylinder to move down to the material handling position, and the gripper cylinder is activated to use the material handling clamp to close and grab the charging plug product. The clamping force is precisely controlled by the pneumatic system. Then, the first cylinder retracts, and the linkage rod pulls the rotating shaft to rotate in the opposite direction, lifting the clamped material to the transfer height. The rotating shaft continues to rotate, causing the gripper cylinder to move the charging plug product horizontally to the top of the discharge rack. The second cylinder resets, the gripper cylinder releases, and the charging plug product accurately falls into the discharge rack. Only a storage container needs to be placed at the bottom of the discharge rack or the production line needs to be connected to automatically complete the material handling operation. The fully automated material handling system not only improves production efficiency, but also solves the contradiction between cleanliness and anti-oxidation performance in traditional processes.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0027] An oiling device for pure copper plugs of electric vehicle charging plugs includes a base 1, a turntable motor 2 fixedly installed at the front end of the top of the base 1, a placement turntable 3 fixedly installed on the drive end of the turntable motor 2, multiple sets of charging plug products 4 placed at equal intervals on the top of the placement turntable 3, an oiling mechanism 5 fixedly installed at the rear end of the top of the base 1, a pressure tank 6 placed on the right side of the base 1, and a material picking mechanism 7 fixedly installed at the front end of the right side of the base 1.

[0028] First, in this embodiment, the specific structure of the oiling mechanism 5 is as follows:

[0029] The oiling mechanism 5 includes a support frame 501 fixedly installed at the rear end of the top of the base 1. A linear module 502 is fixedly installed at the top of the support frame 501. A lifting frame 503 is fixedly installed on the front of the linear module 502. An oiling motor 504 is fixedly installed on the left end of the front of the lifting frame 503. A dispensing valve 505 is fixedly installed on the right end of the front of the lifting frame 503. A connecting pipe 506 is rotatably connected to the bottom end of the dispensing valve 505. The outer side of the connecting pipe 506 is connected to the output end of the oiling motor 504 via a synchronous pulley set 507. An oiling needle 508 is fixedly connected to the bottom end of the connecting pipe 506. The top of the dispensing valve 505 is fixedly connected to the top of the pressure tank 6 via an oil delivery hose 509. The bottom of the oiling motor 504 is fixedly connected to the lifting frame 503 via a mounting plate 510. After the operator positions the charging plug product 4 inside the placement turntable 3, the turntable motor 2 is started to move the placement turntable. 3. Rotation: A small pneumatic press drives the pressure tank 6 to dispense oil into the dispensing valve 505. Under pressure, the dispensing valve 505 dispenses an appropriate amount of oil. During oiling, the linear module 502 drives the lifting frame 503 to descend, causing the oiling needle 508 to pause at the oiling position of the charging plug product 4. The dispensing valve 505 opens to supply oil and simultaneously starts the oiling motor 504, which drives the oiling needle 508 to rotate via the synchronous pulley group 507. The oiling needle 508 is used to apply oil to the inside of the charging plug product 4. Finally, it moves to the material picking mechanism 7 to automatically remove the charging plug product 4. By rotating the oiling, the required amount and uniformity of oil are achieved. By using conventional air pressure in conjunction with rotating oiling, not only can the charging plug product 4 be evenly oiled, but the defects of slow and uneven manual oiling and the problem of oil residue in robot oiling are also effectively solved, ensuring the high precision requirements of the charging plug product 4.

[0030] Furthermore, a collection trough 101 is provided on the top of the base 1 and below the placement turntable 3. An outlet 102 is provided on the front of the base 1 and at the bottom of the collection trough 101. A placement platform 103 is fixedly connected to the front of the base 1 and below the outlet 102. A first collection box 104 is inserted into the placement platform 103. The collection trough 101 is used to collect residual oil or debris dripping during the oiling process. The outlet 102 guides the waste to the outside by gravity. The placement platform 103 and the pluggable first collection box 104 facilitate maintenance personnel to regularly dispose of the waste.

[0031] Then, contoured acupoints 301 are provided inside the turntable 3 at positions corresponding to the multiple sets of charging plug products 4, and the interior of the multiple sets of contoured acupoints 301 are all in contact with the charging plug products 4. The contoured acupoints 301 and the charging plug products 4 are physically in contact, eliminating the risk of positional displacement during the oiling process and ensuring the stability of the relative position of the oiling needle 508 and the charging plug products 4. The layout of multiple sets of contoured acupoints 301 supports the simultaneous completion of the positioning and oiling operations of multiple charging plug products 4 when the turntable 3 rotates and switches work positions.

[0032] Furthermore, the material handling mechanism 7 includes a mounting bracket 701 fixedly installed on the front right side of the base 1. A first cylinder 702 is fixedly installed on the top of the mounting bracket 701, and a rotating shaft 703 is rotatably connected to the front end of the top of the mounting bracket 701. A linkage rod 704 is installed between the output end of the first cylinder 702 and the rotating shaft 703. A second cylinder 705 is fixedly installed at the bottom end of the rotating shaft 703. A gripper cylinder 706 is fixedly installed on the drive end of the second cylinder 705. Material handling blocks 707 are fixedly installed on both sets of grippers of the gripper cylinder 706. A discharge rack 708 is fixedly installed on the right side of the front of the base 1. When the charging plug product 4 is oiled and rotated to the position of the material handling mechanism 7, the first cylinder 702 is activated to extend, pushing the rotating shaft 703 through the linkage rod 704. The second cylinder 705 is driven to rotate, and then the second cylinder 705 drives the gripper cylinder 706 to move down to the material picking position. The gripper cylinder 706 is activated to use the material picking block 707 to close and grab the charging plug product 4. The gripping force is precisely controlled by the pneumatic system. Then the first cylinder 702 retracts, and the linkage rod 704 pulls the rotating shaft 703 to rotate in the opposite direction, lifting the gripped material to the transfer height. The rotating shaft 703 continues to rotate, causing the gripper cylinder 706 to move the charging plug product 4 horizontally to directly above the discharge rack 708. The second cylinder 705 resets, the gripper cylinder 706 releases, and the charging plug product 4 accurately falls into the discharge rack 708. Only a storage container or connection to the production line needs to be placed at the bottom of the discharge rack 708 to automatically complete the material picking operation, further improving production efficiency.

[0033] Secondly, the outer side of the first cylinder 702 is fixedly connected to the top of the mounting bracket 701 via two sets of fixing frames 709. The front end of the linkage rod 704 is fixedly connected to the rotating shaft 703, and the rear end of the linkage rod 704 is rotatably connected to the output end of the first cylinder 702 via the connecting shaft 710. The outer side of the rotating shaft 703 is rotatably connected to the mounting bracket 701 via the bearing 711. A fixing seat 712 is fixedly connected to the bottom end of the rotating shaft 703. A mounting post 713 is fixedly installed on the back of the second cylinder 705, and the mounting post 713 is clamped inside the fixing seat 712. A connecting seat 714 is fixedly installed on the back of the gripper cylinder 706, and the connecting seat 714 is fixedly connected to the drive end of the second cylinder 705. Next, each of the two sets of material-grabbing clamps 707 has a material-grabbing slot 715 on one side opposite to the other. The first cylinder 702 is fixed by the fixing frame 709. The rear end of the linkage rod 704 rotates between the output end of the first cylinder 702 and the connecting shaft 710. The fixing seat 712 and the mounting column 713 are used to assemble the second cylinder 705 and the rotating shaft 703. The connecting seat 714 is used to assemble the second cylinder 705 and the gripper cylinder 706. This modular assembly facilitates maintenance. When the material-grabbing clamps 707 are used to grip the charging plug product 4, the material-grabbing slot 715 can increase the contact surface with the charging plug product 4, thereby ensuring the gripping firmness.

[0034] Finally, the rear end of the discharge rack 708 is fixedly connected to the front of the base 1 via the fixing bracket 716. A filter screen 717 is fixedly installed at the bottom of the discharge rack 708. A collection frame 718 is fixedly installed at the bottom of the discharge rack 708 and below the filter screen 717. A second collection box 719 is inserted into the bottom of the collection frame 718. The discharge rack 708 is fixed to the base 1 via the fixing bracket 716 for easy disassembly and maintenance. The bottom filter screen 717 achieves solid-liquid separation. When the charging plug product 4 rolls inside the discharge rack 708, it can filter out excess oil residue and collect it using the second collection box 719 inside the collection frame 718. The pluggable second collection box 719 makes it easy for maintenance personnel to regularly dispose of waste, further improving the convenience of device maintenance.

[0035] In this embodiment, the specific implementation scenario is as follows: After the operator positions the charging plug product 4 inside the placement turntable 3, the contoured acupoints 301 are physically attached to the charging plug product 4, eliminating the risk of positional displacement during the oiling process and ensuring the stability of the relative position between the oiling needle 508 and the charging plug product 4. The layout of multiple sets of contoured acupoints 301 supports the simultaneous completion of positioning and oiling operations for multiple charging plug products 4 when the placement turntable 3 rotates and switches positions. The turntable motor 2 is started to rotate the placement turntable 3, and the pressure tank 6 is driven by a small pneumatic compressor to dispense oil into the turntable. Under pressure, the dispensing valve 505 dispenses an appropriate amount of oil. During oil application, the linear module 502 drives the lifting frame 503 to descend, causing the oiling needle 508 to pause at the oiling position of the charging plug product 4. The dispensing valve 505 opens to supply oil and simultaneously starts the oiling motor 504, which drives the oiling needle 508 to rotate via the synchronous pulley group 507. The oiling needle 508 is used to apply oil to the inside of the charging plug product 4. After the charging plug product 4 has finished oiling and rotated to the position of the material picking mechanism 7, the first cylinder 702 is activated to extend, pushing through the linkage rod 704. The rotating shaft 703 drives the second cylinder 705 to rotate, and then the second cylinder 705 drives the gripper cylinder 706 to move down to the material picking position. The gripper cylinder 706 is activated to use the material picking clamp 707 to close and grab the charging plug product 4. The gripping force is precisely controlled by the pneumatic system. Then the first cylinder 702 retracts, and the linkage rod 704 pulls the rotating shaft 703 to rotate in the opposite direction, lifting the gripped material to the transfer height. The rotating shaft 703 continues to rotate, causing the gripper cylinder 706 to move the charging plug product 4 horizontally to directly above the discharge rack 708. The second cylinder 705 resets, and the gripper... When cylinder 706 is released, the charging plug product 4 accurately falls into the material rack 708. Simply place a storage container or connect the production line to the bottom of the material rack 708 to automatically complete the material handling operation. The entire operation process is simple and convenient. This utility model effectively solves the defects of slow and uneven manual oiling of the charging plug product 4 by using non-contact rotary oiling technology and precise positioning of contoured acupoints 301. At the same time, it eliminates the risk of contamination caused by brush contact. The fully automated material handling system not only improves production efficiency, but also solves the contradiction between cleanliness and anti-oxidation performance in traditional processes.
