Description

Technical Field

[0001] This invention relates to the field of solar panel testing technology, and more specifically, to a solar panel testing fixture feeding and automatic plug installation mechanism. Background Technology

[0002] A solar simulator is used to simulate sunlight shining on the battery, and then a digital source meter is used to test the battery's IV characteristics to obtain parameters such as open circuit voltage, short circuit current, fill factor, efficiency, series resistance, and parallel resistance. In existing technologies, the test fixture is placed in a designated position, and repeated testing is achieved by connecting the power supply. Repeated experiments generally require the use of a robotic arm. However, in existing technologies, the robotic arm is prone to damage to the plug and socket due to poor control of the insertion force during the process of picking up the plug and inserting it into the socket, and it is also prone to misalignment.

[0003] Therefore, it is necessary to develop a solar panel testing fixture feeding and automatic plug installation mechanism. Summary of the Invention

[0004] This invention provides a solar panel testing fixture loading and automatic plug installation mechanism to solve the above problems.

[0005] To achieve the above objectives, embodiments of the present invention provide a solar panel testing fixture feeding and automatic plug installation mechanism, comprising: a support frame, a fixture gripper mechanism, a plug gripping mechanism, and a socket limiting mechanism. The fixture gripper mechanism is disposed on one side of the support frame, and the plug gripping mechanism and the socket limiting mechanism are disposed at the bottom of the support frame. A plug pushing mechanism is disposed on the support frame above the plug gripping mechanism, and a plug compensation mechanism is disposed on the support frame above the socket limiting mechanism. The main function of the fixture gripper mechanism is to grip the solar panel testing fixture and place it in a suitable position. The socket limiting mechanism is used to lock onto the socket on the fixture. The plug gripping mechanism is used to insert the plug through the socket limiting mechanism into the socket on the fixture. The plug compensation mechanism is used to compensate for the travel differences caused by plugs of different sizes.

[0006] Furthermore, the plug compensation mechanism includes a first cylinder, which is connected to the socket limiting mechanism.

[0007] Furthermore, the plug pushing mechanism includes a second cylinder, which is connected to the plug gripping mechanism.

[0008] Furthermore, the tooling gripper mechanism includes a gripping cylinder, which is installed on one side of the support frame. Two limiting baffles are provided on one side of the gripping cylinder. The limiting baffles are made of PE material, and a V-shaped groove is opened on one side of the limiting baffle. A silicone pad is embedded in the V-shaped groove.

[0009] Furthermore, the plug gripping mechanism includes a plug clamping cylinder and a socket picking cylinder, both of which are mounted on the support frame.

[0010] Furthermore, the plug clamping cylinder is equipped with plug claws, and the plug claws are made of polytetrafluoroethylene.

[0011] Furthermore, the socket pickup cylinder is equipped with wire clamps, and the wire clamps are made of aluminum.

[0012] Furthermore, the socket limiting mechanism includes a blocking structure, a mounting base is provided at the bottom of the blocking structure, and an elastic protective pad is provided on the support frame on one side of the mounting base. The elastic protective pad is made of silicone.

[0013] Furthermore, a guide block is provided on the side of the mounting base away from the elastic protective pad, and a guide hole is provided on the guide block.

[0014] Furthermore, a flange is provided on the top of the support frame, the flange being adapted to connect with a robotic arm.

[0015] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:

[0016] 1. By setting up a plug compensation mechanism and a plug pushing mechanism, the plug compensation mechanism is used to ensure that the battery panel test plug and two test heads of different sizes can be fully matched alternately, and the plug pushing mechanism is used to adjust different profiles to adapt to different test fixtures and different battery test plugs.

[0017] 2. The installation accuracy of the test fixture is ensured by setting a limit baffle. By setting a V-shaped groove on the limit baffle, the test fixture can be prevented from being thrown out by the rapid rotation of the robot arm.

[0018] 3. By setting up silicone pads, not only can the friction between the test fixture and the fixture be increased, but the soft contact can also prevent wear on the test fixture.

[0019] 4. By setting wire clamps and plug clamps, the test plug leads can be clamped and blocked during the process, while the battery cell test plugs are clamped to avoid being pinched during installation.

[0020] 5. By setting elastic protective pads, the connection between the socket and the plug is buffered and protected against impact, thus solving the problem of short service life of electrical connection tools.

[0021] 6. By setting guide blocks and guide holes, the plug can pass through and connect with the socket that is stuck on the setting seat, avoiding the phenomenon of misalignment and inability to insert, thus solving the problem of low success rate when plugging in the plug.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] Please see Figure 1 ; Figure 1 This is a perspective view of the preferred embodiment of the solar panel testing fixture loading and automatic plug installation mechanism of the present invention. Figure 1As shown, this invention provides a solar panel testing fixture feeding and automatic plug installation mechanism, including: a support frame 100, with a flange 200 on the top of the support frame 100, the flange 200 being suitable for connection to a robotic arm. The robotic arm can control the overall raising and lowering, left and right movement, and angle rotation of the support frame 100. The plug installation mechanism also includes a fixture gripper mechanism 500, a plug gripping mechanism 600, and a socket limiting mechanism 700. It should be further explained that the main function of the fixture gripper mechanism 500 is to grip the solar panel testing fixture and place it in a suitable position. The socket limiting mechanism 700 is used to lock onto the socket on the fixture. The plug gripping mechanism 600 is used to insert the plug through the socket limiting mechanism 700 into the socket on the fixture to achieve the power connection effect. The fixture gripper mechanism 500 is located on one side of the support frame 100, and the plug gripping mechanism 600 and the socket limiting mechanism 700 are located at the bottom of the support frame 100.

[0031] Please continue reading. Figure 1 and combined Figure 2 , Figure 2 This is a front view schematic diagram of the solar panel testing fixture loading and automatic plug installation mechanism of the present invention. Figure 1 and 2 As shown, to address the issue of incomplete insertion caused by differences in the length of male and female plugs, a plug pushing mechanism 400 is installed on the support frame 100 above the plug gripping mechanism 600. The plug pushing mechanism 400 is used to adjust the fit of different profiles to accommodate different testing fixtures and battery test plugs. The plug pushing mechanism 400 includes a second cylinder connected to the plug gripping mechanism 600. A plug compensation mechanism 300 is installed on the support frame 100 above the socket limiting mechanism 700. The plug compensation mechanism 300 includes a first cylinder connected to the socket limiting mechanism 700. The plug compensation mechanism 300 ensures that the battery panel test plug and two test heads of different sizes alternately and completely fit together.

[0032] Please continue reading. Figure 1 and combined Figure 3 , Figure 3 This is a perspective view of the preferred embodiment of the tooling gripper mechanism of the present invention. Figure 1 and 3As shown, the tooling gripper mechanism 500 includes a gripping cylinder 504, which is installed on one side of the support frame 100. Two limit baffles 501 are provided on one side of the gripping cylinder 504. The limit baffles 501 are made of PE material and are used to ensure the installation accuracy of the test tooling. A V-shaped groove 502 is provided on one side of the limit baffle 501. The V-shaped groove 502 is used to prevent the robot arm from quickly rotating and throwing the test tooling out. A silicone pad 503 is embedded in the V-shaped groove 502. The silicone pad 503 is used to increase the contact friction with the tooling and at the same time, the soft contact prevents the test tooling from wearing.

[0033] Please continue reading. Figure 1 and combined Figure 4 , Figure 4 This is a front view schematic diagram of the plug gripping mechanism of the present invention. Figure 1 and 4 As shown, the plug gripping mechanism 600 includes a plug clamping cylinder 601 and a socket picking cylinder 602, both mounted on the support frame 100. The plug clamping cylinder 601 is equipped with plug grippers 604, which grip the battery cell test plug during installation to prevent injury. The plug grippers 604 are made of polytetrafluoroethylene (PTFE). The socket picking cylinder 602 is equipped with wire grippers 603, which grip the test plug lead and act as a barrier during engagement. The wire grippers 603 are made of aluminum.

[0034] Please continue reading. Figure 1 and combined Figure 2 and 5 , Figure 5 For the present invention Figure 1 A magnified structural diagram at point A in the middle. (See diagram below.) Figure 1 , 2As shown in Figure 5, the socket limiting mechanism 700 includes a blocking structure 701. A mounting base 702 is provided at the bottom of the blocking structure 701. It should be further noted that the mounting base 702 has a groove that matches the outer contour of the socket. An elastic protective pad 704 is provided on the support frame 100 on one side of the mounting base 702. The main function of the elastic protective pad 704 is to prevent excessive impact force between the socket and plug during power connection, which could cause the socket to shift backward and hit the elastic protective pad 704. In the prior art, a cylinder is used at the position of the elastic protective pad 704 to perform a limiting function. However, the cost of using a cylinder in this position is high, and its buffering and anti-collision effect is inferior to that of a silicone pad. Therefore, the problem of low service life of the power connection fixture can be solved by using an elastic protective pad 704. The elastic protective pad 704 is made of silicone. A guide block 703 is provided on the side of the setting base 702 away from the elastic protective pad 704. A guide hole 705 is provided on the guide block 703. The guide hole 705 is used to allow the plug to pass through and connect with the socket that is stuck on the setting base 702, so as to avoid the phenomenon of misalignment and inability to insert. Thus, the guide hole 705 solves the problem of low success rate when plugging in the plug.

[0035] The specific workflow of this invention is as follows: The tooling gripper mechanism 500 first places the tooling in a designated position, at which point the position of the socket on the tooling is also determined. Then, the plug gripping mechanism 600 drives the plug gripper 604 to pick up the plug. The plug gripper 604 is designed to be floating. The socket limiting mechanism 700 clamps the tooling and positions it. The setting seat 702 uses a slope designed by a special positioning mechanism to accurately position the socket. The plug pushing mechanism 400 starts and pushes forward. The plug, guided by a guide block 703 of a special material, cooperates with the floating plug gripper 600 to achieve the plug's automatic angle adjustment position and quickly inserts into the socket. When the male plug is inserted, the plug compensation mechanism 300 starts and pushes it forward to a designated position to compensate for the stroke difference caused by the short male plug.

[0036] In summary, the beneficial effects of this invention are as follows: By setting up a plug compensation mechanism 300 and a plug pushing mechanism 400, the plug compensation mechanism 300 ensures that the battery panel test plug and two test heads of different sizes alternately and completely fit together; the plug pushing mechanism 400 adjusts the fit of different profiles to different test fixtures and different battery test plugs; the limit baffle 501 ensures the installation accuracy of the test fixture; the V-shaped groove 502 on the limit baffle 501 prevents the robot arm from quickly swinging the test fixture out; and the silicone pad 503 increases the contact friction with the fixture. It can also prevent wear of the test fixture through soft contact. By setting wire clamps 603 and plug clamps 604, it can clamp the test plug leads and act as a barrier during the engagement. At the same time, it can clamp the battery cell test plug to avoid pinching damage during installation. By setting elastic protective pads 704, it can buffer and prevent collisions during the connection of the socket and plug, solving the problem of short service life of electrical connection fixtures. By setting guide blocks 703 and guide holes 705, the plug can pass through and connect with the socket that is stuck on the setting seat 702, avoiding the phenomenon of misalignment and inability to insert, solving the problem of low success rate when inserting plugs.

The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
