Description

Technical Field

[0001] This utility model relates to the field of material cart components, specifically an aging test component. Background Technology

[0002] Aging test equipment generally consists of three parts: a trolley, a material cart, and a test chamber. The aging test fixture with the PCBA board is placed on the material cart, and the material cart is sent to the front of the test chamber by the trolley. Then the material cart is moved into the test chamber to simulate the aging environment and complete the test.

[0003] Currently, when the testing equipment is in use, it requires two employees to push the cart to the front of the testing chamber. One employee holds the cart in place, and the other employee pushes the cart into the testing chamber, which increases labor costs.

[0004] Meanwhile, during aging tests, the contact connectors on the material cart must be interlocked with the contact interfaces in the test chamber. When the material cart enters the test chamber, misalignment can easily occur, preventing the contact connectors from interlocking with the contact interfaces and causing damage. Utility Model Content

[0005] Purpose of the utility model: To provide an aging test component to solve the above-mentioned problems existing in the prior art.

[0006] Technical solution: An aging test component, comprising:

[0007] A trolley, a material cart mounted on the trolley, and a test chamber for placing the material cart;

[0008] The trolley and the test chamber are equipped with a first track and a second track that are aligned with each other.

[0009] The material cart is equipped with wheels at the bottom that are compatible with the first and second tracks, and has a primary positioning post and a floating joint on its side. The floating joint includes:

[0010] A floating frame, wherein the floating frame is equipped with secondary positioning posts and connector pins;

[0011] A floating component is provided at both ends of the floating frame, including a connecting shaft connected to the material cart, two sets of floating discs sleeved on the connecting shaft, and through holes at both ends of the floating frame. A protrusion is provided in the through hole and the protrusion is located between the two sets of floating discs.

[0012] The test chamber is equipped with docking holes that are compatible with the primary positioning post and the secondary positioning post. The diameter of the docking holes gradually decreases from the side closest to the primary positioning post and the secondary positioning post to the other side.

[0013] This invention uses a first and second track to initially limit the movement of the material cart to the test chamber. Then, a first-level positioning post cooperates with the docking hole to complete the second positioning. After two positioning operations, the position of the material cart is roughly positioned. Even if there is a slight misalignment, the second-level positioning post can be used with the docking hole to drive the floating part to perform adaptive movement, so that the connector pin can be finely adjusted and can be inserted with the contact point. The diameter of the docking hole gradually decreases, so that the connector pin gradually aligns with the contact point, and finally the insertion work is completed.

[0014] A fixing buckle was designed to work with the buckle frame. When the trolley moves to the side of the test chamber, the fixing buckle and the buckle groove are used with the casters to fix the trolley. Thus, only one employee is needed to fix the trolley and push the trolley in, saving labor costs.

[0015] In a further embodiment, the test chamber is provided with contacts adapted to the stylus.

[0016] In a further embodiment, the trolley includes a frame and a fixing buckle disposed on the side of the frame, the fixing buckle having a chamfer, and casters provided at the bottom of the frame;

[0017] The first track is mounted on the vehicle frame.

[0018] In a further embodiment, the test chamber is provided with a buckle frame, and the buckle frame has a buckle groove that is adapted to the fixing buckle.

[0019] In a further embodiment, the material cart includes a frame and a multi-layer placement rack mounted on the frame for placing an aging test fixture with a PCBA board. The aging test fixture is connected to a contact pin via a cable to supply power to the aging test fixture. Power is supplied to the contact pin through contact with a contact point, and the contact point is connected to an external power source. The primary positioning column and connecting shaft are connected to the frame.

[0020] Beneficial effects: This utility model discloses an aging test component. This utility model uses a first track and a second track to initially limit the movement of the material cart to the test chamber. Then, the first-level positioning post cooperates with the docking hole to complete the second positioning. After the two positionings, the position of the material cart is roughly positioned. Even if there is a slight misalignment, the second-level positioning post can be used in conjunction with the docking hole to drive the floating part to perform adaptive movement, so that the connector pin can be finely adjusted and can be inserted with the contact. The diameter of the docking hole decreases from large to small, so that the connector pin gradually aligns with the contact and finally completes the insertion.

[0021] A fixing buckle was designed to work with the buckle frame. When the trolley moves to the side of the test chamber, the fixing buckle and the buckle groove are used with the casters to fix the trolley. Thus, only one employee is needed to fix the trolley and push the trolley in, saving labor costs. Attached Figure Description

[0031] This application relates to an aging test component, which will be explained in detail below through specific embodiments.

[0032] An aging test component, comprising:

[0033] A trolley 1, a material cart 2 mounted on the trolley 1, and a test chamber 3 for placing the material cart 2;

[0034] The trolley 1 and the test chamber 3 are equipped with a first track 13 and a second track that are aligned with each other.

[0035] The material cart 2 is equipped with wheels at the bottom that are compatible with the first track 13 and the second track, and has a primary positioning post 22 and a floating joint 23 on its side. The floating joint 23 includes:

[0036] A floating frame 231 is provided with a secondary positioning post 233 and a connector pin 232.

[0037] The floating component 234 is disposed at both ends of the floating frame 231, including a connecting shaft 234A connected to the material cart 2, two sets of floating disks 234B sleeved on the connecting shaft 234A, and through holes 231A opened at both ends of the floating frame 231. A protrusion 231B is provided in the through hole 231A, and the protrusion 231B is located between the two sets of floating disks 234B.

[0038] There is a gap between the two sets of floating disks 234B and the through hole 231A, and there is a gap between the protrusion 231B and the connecting shaft 234A;

[0039] The test chamber 3 is provided with a docking hole that is adapted to the primary positioning post 22 and the secondary positioning post 233. The diameter of the docking hole gradually decreases from the side closer to the primary positioning post 22 and the secondary positioning post 233 to the other side.

[0040] This utility model uses a first track 13 and a second track to initially limit the movement of the material cart 2 to the position inside the test chamber 3. Then, the first-level positioning post 22 cooperates with the docking hole to complete the second positioning. After two positionings, the position of the material cart 2 is roughly positioned. Even if there is a slight misalignment, the second-level positioning post 233 can be used in conjunction with the docking hole to drive the floating part 234 to perform adaptive movement, so that the connector pin 232 can be finely adjusted and can be inserted with the contact point. The diameter of the docking hole decreases from large to small, so that the connector pin 232 gradually aligns with the contact point and finally completes the insertion work.

[0041] Meanwhile, a fixing buckle 12 was designed to work with the buckle frame 31. When the trolley 1 moves to the side of the test chamber 3, the trolley 1 is fixed by the fixing buckle 12 and the buckle groove with the caster. Thus, only one employee is needed to complete the fixing of the trolley 1 and the pushing of the material cart 2, saving labor costs.

[0042] The test chamber 3 is equipped with contacts that are compatible with the stylus.

[0043] The trolley 1 includes a frame 11 and a fixing buckle 12 disposed on the side of the frame 11. The fixing buckle 12 has a chamfer, and the bottom of the frame 11 is provided with casters.

[0044] The design of the trolley 1 allows the material cart 2 to be flush with the test chamber 3, thereby reducing bumps and tilting when the material cart 2 enters the test chamber 3;

[0045] The first track is mounted on the frame 11.

[0046] The test chamber 3 is provided with a buckle 31, and the buckle 31 has a buckle groove that is adapted to the fixing buckle 12.

[0047] The material cart 2 includes a frame 21 and a multi-layer placement rack on the frame 21 for placing an aging test fixture with a PCBA board. The aging test fixture is connected to a contact pin via a cable to power the aging test fixture. Power is supplied to the contact pin through contact with the contact point. The contact point is connected to an external power source.

[0048] The primary positioning column 22 and the connecting shaft 234A are connected to the frame 21.

[0049] Working principle description: During operation, the material cart 2 is placed on the trolley 1, and the aging test fixture with PCBA board is placed on the material cart 2. The operator pushes the trolley 1 so that the fixing buckle 12 engages with the buckle groove on the buckle frame 31, and with the help of casters, the trolley 1 is fixed. After fixing, the operator pushes the material cart 2. Through the design of the first track 13 and the second track, the material cart 2 can smoothly enter the test chamber 3 and initially position the material cart 2. The operator continues to push the material cart 2, and the first positioning post 22 cooperates with the docking hole to complete the second positioning. After the two positioning, the position of the material cart 2 is roughly positioned. Even if there is a slight misalignment, the second positioning post 233 can be used in conjunction with the docking hole to drive the floating part 234 to perform adaptive movement, so that the connector pin 232 can be finely adjusted and can be inserted with the contact. The diameter of the docking hole decreases from large to small, so that the connector pin 232 gradually aligns with the contact, and finally the insertion work is completed.

[0050] When the floating component 234 adapts, it gradually connects with the docking hole whose diameter decreases through the secondary positioning column 233. The secondary positioning column 233 will drive the floating frame 231 to move adaptively along the connecting shaft 234A.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
