Description

Technical Field

[0001] This utility model relates to the field of product testing technology, specifically to a battery tray testing component and tooling. Background Technology

[0002] Currently, phased array testing equipment includes an open container. The product to be tested is typically placed inside the open container, and a coupling agent is injected until it covers the weld seam to be tested. Finally, a robotic arm moves the ultrasonic probe to the designated location on the weld seam for subsequent testing. Deionized water is typically used as the coupling agent; therefore, after testing, the water can be drained simply by opening the drain port at the bottom of the container.

[0003] However, the aforementioned testing equipment is only applicable to products with smooth surfaces and no concave structures. These products, due to their smooth surface, will not carry water out during removal from the container. For other products with concave structures, such as battery trays (typically used in electric vehicle battery modules), which have complex structures and concave areas on their surfaces, coupling agent tends to accumulate in these areas during testing. After testing, traditional phased array testing equipment cannot effectively remove this accumulated coupling agent, resulting in a large amount of coupling agent being carried out with the product when the battery tray is removed. This not only wastes resources but may also pollute the working environment. Furthermore, the carried-out coupling agent may affect the accuracy of subsequent tests and even damage the equipment. Therefore, the aforementioned testing equipment is not suitable for products with concave structures.

[0004] Based on this, we propose a battery tray detection component to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a battery tray detection component. This detection component can change the position of the pipe relative to the battery tray through a motion mechanism, so that the pipe with water spraying and water suction functions can move freely in the battery tray and can perform water spraying or water suction work according to the actual scenario.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A battery tray testing assembly includes an ultrasonic probe, a worktable, and a coupling agent actuating component disposed on the worktable. The coupling agent actuating component includes a pipe located above the worktable and a motion mechanism for driving the pipe to perform two-dimensional movements. The pipe is configured as multiple pipes and is divided into a water spray pipe and a water suction pipe, and the water spray pipe and the water suction pipe can be selectively operated. When the battery tray to be tested is placed on the worktable, the openings of the water spray pipe and the water suction pipe can be moved into the battery tray by the motion mechanism to sequentially realize the water spraying and water suction operations inside the battery tray.

[0008] As a further embodiment of this utility model: both the spray pipe and the suction pipe are arranged vertically, and the openings of each pipe facing the battery tray are flush, so that when each pipe moves into the battery tray, the opening of each pipe is in contact with the bottom wall of the battery tray.

[0009] As a further embodiment of this utility model: the motion mechanism is configured as a two-dimensional motion mechanism for driving the pipe to perform horizontal and vertical movements. The two-dimensional motion mechanism includes a first drive source on the workbench and a second drive source on the execution end of the first drive source. The working direction of the execution end of the first drive source is perpendicular to the working direction of the execution end of the second drive source. A long strip for pipe installation is fixedly provided on the execution end of the second drive source.

[0010] As a further aspect of this invention, the detection assembly also includes a clamp disposed on the workbench for holding the battery tray.

[0011] As a further embodiment of this utility model: the fixture includes multiple clamping members arranged in a surrounding manner on the worktable, the execution ends on the multiple clamping members form an adjustable limiting area, the coupling agent action member is located outside the limiting area, the fixture also includes multiple pressing members provided on the worktable, the multiple pressing members are used to apply a force toward the worktable to the battery tray on the limiting area.

[0012] As a further embodiment of this utility model: a drain plate is provided on the top of the workbench, and multiple pads for supporting the battery tray are provided on the area of ​​the drain plate within the limiting zone.

[0013] As a further embodiment of this utility model: the detection component also includes a feeding robot located next to the workbench. The end effector of the feeding robot is equipped with a dual-head drive source. Both execution ends of the dual-head drive source are fixedly equipped with clamping plates, and an adjustable clamping area is formed between the two clamping plates.

[0014] As a further embodiment of this invention, the detection assembly also includes a detection robot arm located beside the workbench, with the ultrasonic probe fixedly mounted on the end effector of the detection robot arm.

[0015] This utility model also proposes a tooling for using the above-mentioned battery tray detection component, including a water pumping component. The water pumping component includes a third drive source on the workbench and a bracket on the execution end of the third drive source. A water pumping pipe is rotatably arranged on the bracket. The end of the water pumping pipe facing the limiting area is bent so that the water pumping pipe is arranged in an L-shape. A fourth drive source is provided on the bracket for driving the water pumping pipe to rotate along its axial direction. When the bent end of the water pumping pipe is driven into the cavity of the battery tray by the third drive source, the fourth drive source can drive the water pumping pipe to rotate until the bent end of the water pumping pipe fits against the bottom wall of the cavity of the battery tray.

[0016] As a further embodiment of this utility model: the fourth drive source is hinged on the bracket and arranged perpendicularly to the third drive source. The execution end of the fourth drive source is provided with a transition block, and a connecting piece that is fixedly connected to the water pumping pipe is movably hinged on the transition block.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This detection component is designed with a coupling agent action element that has both water spraying and water absorption functions. The water spraying pipe and water absorption pipe in the coupling agent action element work alternately, which can not only realize the delivery of coupling agent into the battery tray, but also effectively remove water from the battery tray, thereby improving detection accuracy and efficiency.

[0019] 2. By further optimizing the arrangement of the spray pipe and the suction pipe, the spray pipe will not splash when delivering water to the battery tray because its nozzle is in contact with the bottom of the battery tray. At the same time, the suction pipe can completely remove the water from the battery tray because its nozzle is in contact with the battery tray.

[0020] 3. The addition of clamps allows the battery tray to be stably held during the testing process, avoiding testing errors caused by shaking or displacement, and improving the accuracy and reliability of the testing.

[0021] 4. The design of the fixture fully considers the diversity of battery trays. Through the combination of adjustable limiting areas and clamping parts, it achieves stable clamping of battery trays of different sizes, while ensuring the smooth progress of the testing process.

[0022] 5. The pad not only provides extra support for the battery tray during the testing process, but also achieves dry and wet separation between the battery tray and the drain board, so that the battery tray can still be in a relatively dry state after testing, which facilitates the subsequent processing and production of the battery tray.

[0023] 5. The designed water extraction component is suitable for battery tray products with relatively complex concave structures. It can effectively extract residual moisture in the cavity of the battery tray, further improving the dryness of the battery tray after inspection.

[0024] 6. The water extraction pipe is designed with an L-shaped structure, which allows its curved end to rotate flexibly and fit tightly against the bottom wall of the battery tray cavity, ensuring thorough and uniform water extraction and further improving the practicality of the tooling.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] It should be noted that the present invention aims to solve the problem of coupling agent accumulation in products with concave structures during the testing process. The present invention takes a battery tray as the product and water as the coupling agent as an example. When the product to be tested is a battery tray, the part to be tested is the weld seam on the inner side of the bottom of the battery tray. Therefore, it is only necessary to deliver the coupling agent into the battery tray until it covers the weld seam before testing can be performed.

[0035] Example 1:

[0036] like Figures 1-6 As shown, a battery tray inspection assembly includes a workbench 3 and an inspection robot 13 located beside the workbench 3. An ultrasonic probe 1 is mounted on the end effector of the inspection robot 13. After the battery tray a is placed in a designated position on the workbench 3, the inspection robot 13 can drive the ultrasonic probe 1 to the weld seam inside the battery tray a for inspection. A drain plate 2 (with multiple drainage holes evenly distributed on it) is provided on the top of the workbench 3 to prevent coupling agent residue from remaining on the top of the workbench 3. Multiple pads 9 for supporting the battery tray a are evenly distributed on the drain plate 2. During operation, the battery tray a can be directly placed on the multiple pads 9. A coupling agent actuating element 4 is provided on the drain plate 2. The coupling agent actuating element 4 has the function of delivering coupling agent into the battery tray a to be inspected, and also has the function of sucking out the coupling agent from the battery tray a after inspection. During use, the two functions are used selectively and not simultaneously. Based on the combined arrangement of the drain plate 2, the pad 9, and the coupling agent 4, the drain plate 2 can always remain dry thanks to the drainage holes on it. The pad 9 will lift the battery tray a away from the drain plate 2 to achieve dry and wet separation. In subsequent testing, the coupling agent 4 can absorb the coupling agent in the battery tray a, so that the battery tray a can still be relatively dry after testing, which is convenient for the subsequent processing and production of the battery tray a.

[0037] like Figures 1-4As shown, the coupling agent 4 mentioned above includes a pipe 5 located above the drain plate 2, and a motion mechanism 6 for driving the pipe 5 to perform horizontal and vertical movements, so that the pipe 5 can enter the battery tray a to perform water spraying and water absorption. The motion mechanism 6 can be any conventional technology in the prior art, such as a three-dimensional motion mechanism or a two-dimensional motion mechanism. This paper preferentially selects a two-dimensional motion mechanism. The two-dimensional motion mechanism includes a first drive source 601 set on the drain plate 2 and a second drive source 602 set on the execution end of the first drive source 601. The working direction of the execution end of the first drive source 601 is perpendicular to the working direction of the execution end of the second drive source 602. A long strip 603 for mounting the pipe 5 is fixedly set on the execution end of the second drive source 602. When the battery tray a is placed on multiple pads 9, the first drive source 601 and the second drive source 602 can be driven to work, so that the pipe 5 enters the battery tray a and performs water spraying. After the water volume exceeds the weld, the pipe 5 stops spraying water and returns to the initial position. After subsequent testing is completed, the first drive source 601 and the second drive source 602 can be used again to drive the pipe 5 into the battery tray a to perform water suction.

[0038] like Figures 1-2 and Figure 4 As shown, to better achieve the water spraying and suction work of pipe 5 on battery tray a, this application sets multiple pipes 5, divided into water spray pipes and water suction pipes. The water spray pipes and water suction pipes are arranged in parallel on the carrying strip 603, and one of the water spray pipes and water suction pipes can be used at a time. The figure shows the case where the total number of water spray pipes and water suction pipes is three. In actual application, this number is not limited to three. Under the premise that the total number of water spray pipes and water suction pipes is three, one water spray pipe and two water suction pipes can be set, or two water spray pipes and one water suction pipe can be set. When the battery tray a to be tested is placed on the drain plate 2, the nozzles of the water spray pipes and water suction pipes can be moved into the battery tray a by the motion mechanism 6, so as to realize the water spraying and water suction work in the battery tray a in sequence.

[0039] like Figure 4As shown, to prevent splashing during the spraying of water into battery tray a, and to ensure the suction pipe can completely remove water from battery tray a, this application arranges both the spraying and suction pipes vertically, with the pipe openings facing battery tray a flush, so that when each pipe moves into battery tray a, its opening is in close contact with the bottom wall of battery tray a. This contact is achieved by leaving a slight gap. This ensures that splashing does not occur when the spraying pipe delivers water to battery tray a because its opening is close to the bottom of battery tray a, and that the suction pipe can completely remove water from battery tray a because its opening is close to the bottom of battery tray a.

[0040] like Figures 1-3 As shown, in order to ensure that the battery tray a can be stably placed on the drain plate 2, this application also includes a clamp disposed on the drain plate 2 for holding the battery tray a. Specifically, the clamp includes multiple clamping members 7 arranged in a surrounding manner on the drain plate 2, and multiple pressing members 8 disposed on the drain plate 2. The actuating ends of the multiple clamping members 7 form an adjustable limiting zone. The battery tray a can be placed within the limiting zone to be clamped and limited by the limiting zone. The multiple pressing members 8 are used to apply a force toward the drain plate 2 to the battery tray a in the limiting zone. Therefore, under the clamping action of the clamping members 7 and the pressing action of the pressing members 8, the battery tray a can be stably limited to a designated position on the drain plate 2. With the existence of the limiting zone, the coupling agent actuating member 4 needs to be located outside the limiting zone, and the pipe 5 on the coupling agent actuating member 4 can be driven into the battery tray a in the limiting zone.

[0041] For example Figures 1-3 As shown, in order to improve the detection efficiency and the automation level of this application, this application also includes a feeding robot 10 located next to the workbench 3. The end effector of the feeding robot 10 is equipped with a dual-head drive source 11. Both execution ends of the dual-head drive source 11 are fixedly equipped with clamping plates 12, and an adjustable clamping area is formed between the two clamping plates 12. This clamping area can clamp the battery tray a in the storage area and transfer it to the limiting area through the feeding robot 10. After the battery tray a is subsequently detected, the clamping area can be used again to clamp the battery tray a and transfer it to the finished product area through the feeding robot 10.

[0042] Example 2:

[0043] In some products with concave structures, there may also be cavities with openings, such as the battery tray a in this application. The battery tray a is composed of a frame on all four sides, with a cavity inside the frame. A waist-shaped hole b, communicating with the cavity, is also provided on the frame. With this product structure design, when water is injected into the battery tray a until it covers the weld seam, if the waist-shaped hole b on the frame is below the liquid surface, a certain amount of water will enter the cavity. Therefore, even if the water in the battery tray a is subsequently sucked away using a suction pipe, the water below the waist-shaped hole b will still be isolated within the cavity.

[0044] like Figure 1 and Figures 5-6 As shown, based on the above situation, we propose a tooling for using the aforementioned battery tray detection assembly. This tooling includes a water-pumping component 14, which includes a third drive source 1401 mounted on the drain plate 2 and a bracket 1402 mounted on the execution end of the third drive source 1401. The bracket 1402 is located above the third drive source 1401, and a water-pumping pipe 1403 is rotatably mounted on the bracket 1402. The water-pumping pipe 1403 is bent towards the limiting area, so that the water-pumping pipe 1403 is arranged in an L-shape. The bracket 1402 is provided with a fourth drive source 1404 for driving the water-pumping pipe 1403 to rotate along its axial direction. When the battery tray a is placed on the limiting area, the arrangement between the water-pumping pipe 1403 and the battery tray a can be adjusted by... Figure 6 To illustrate, at this point, the bent end of the water suction pipe 1403 will be aligned with the position of the oblong hole b on the battery tray a. When the battery tray a is inspected and water needs to be pumped out of the cavity, the third drive source 1401 can first drive the bent end of the water suction pipe 1403 into the cavity of the battery tray a, and then the fourth drive source 1404 drives the water suction pipe 1403 to rotate. Figure 6 When the initial state of the bent end of the water suction pipe 1403 is horizontal, the rotation angle of the water suction pipe 1403 can be ninety degrees until the bent end of the water suction pipe 1403 is in contact with the bottom wall of the cavity of the battery tray a. Then, the water suction function of the water suction pipe 1403 can be activated to remove the water temporarily stored in the cavity. The contact state described here is the same as the contact state described above.

[0045] For example Figures 5-6As shown, specifically, the design for the fourth drive source 1404 to drive the water pipe 1403 to rotate can be set using conventional techniques in the prior art, such as the meshing transmission between the gear clamped on the outside of the water pipe 1403 and the rack set on the execution end of the fourth drive source 1404, or conventional hinge transmission. This article takes hinge transmission as an example: the fourth drive source 1404 is hinged on the bracket 1402 and arranged perpendicularly to the third drive source 1401. The execution end of the fourth drive source 1404 is provided with a transition block 1405. A connecting piece 1406 fixedly connected to the water pipe 1403 is movably hinged on the transition block 1405. The operation of the execution end of the fourth drive source 1404 can rely on its own movement and the movement of the transition block 1405 to drive the rotation of the connecting piece 1406, thereby realizing the rotation of the water pipe 1403.

[0046] It should be noted that the spray pipe, suction pipe, and pumping pipe 1403 can all be connected to corresponding devices via flexible hoses to achieve their functions. For example, the spray pipe can be connected to a water pump via a flexible hose, and both the suction pipe and pumping pipe 1403 can be connected to a negative pressure device via flexible hoses. Furthermore, the various drive sources in this application can all be configured as cylinders or hydraulic cylinders with guiding functions; this document does not limit the type of drive source selected.

[0047] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
