Description

Technical Field

[0001] This utility model relates to the technical field of battery production, and in particular to a mechanical device for preventing abnormal drop of a tray. Background Technology

[0002] During battery production, a series of tests are required to ensure battery quality and safety. Currently, the industry commonly uses pallets to support batteries and a conveyor line to transfer the pallets to testing equipment to complete the testing. Specifically, after the pallet is transported to the designated position, a lifting mechanism lifts the pallet to the preset testing height, and then a probe assembly located above the lifting mechanism connects with the battery in the pallet to detect parameters such as electrical performance.

[0003] However, in actual production processes, to improve production efficiency, the conveyor line needs to operate continuously. That is, when a pallet is lifted and in the testing state, the conveyor line below it still needs to continuously transport subsequent pallets to wait for them to enter the testing stage. During this process, the existing equipment lacks a protection mechanism to prevent abnormal falls of pallets in the lifting state, resulting in low safety and potential risks. Since the pallets being lifted for testing usually carry multiple sets of batteries and have a certain weight, if the lifting mechanism malfunctions or fails unexpectedly, the pallet will fall instantly, which could easily lead to a major safety accident. This issue urgently needs to be addressed. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a mechanical device to prevent the abnormal drop of a pallet.

[0005] The above-mentioned inventive objective of this application is achieved through the following technical solutions: A mechanical device for preventing abnormal drop of a battery tray includes a frame, on which a conveying module, a lifting module, a probe detection module and an anti-drop linkage module are provided. The conveying module is used to horizontally convey the battery tray. The lifting module includes a lifting frame and a lifting drive. The lifting frame is used to support the battery tray and is vertically slidably connected to the frame. The lifting drive is provided on the frame and is used to drive the lifting frame to lift. The probe detection module is set on the frame and located above the lifting module. There is a detection position on the sliding path of the lifting frame. When the lifting frame is in the detection position, the probe detection module is used to dock with the battery tray on the lifting frame to perform the battery detection process. There is a locking position on the conveying path of the battery tray. When the lifting frame is in the detection position and the battery tray is in the locking position, the anti-fall linkage module is used to support the lifting frame.

[0006] Preferably, the anti-fall linkage module includes a first linkage link, a second linkage link, a fixed ear, an ear fixing seat, and a horizontal support link. The length direction of the first linkage link is the same as the conveying direction of the battery tray. A follower wheel is rotatably provided on the first linkage link. The follower wheel is located on the conveying path of the battery tray and is used to abut against the bottom of the battery tray. The ear seat fixing base is vertically fixed to the frame, and the fixed ear seat is fixedly installed on the ear seat fixing base. The horizontal support connecting rod is located at the bottom of the lifting frame and is slidably connected to the ear seat fixing base.

The second linkage connecting rod is rotatably connected to the fixed ear seat and an elastic element is provided between the second linkage connecting rod and the ear seat fixing base. The elastic element is used to continuously provide the second linkage connecting rod with a pulling force opposite to the battery tray conveying direction. When the lifting frame is in the detection position and the battery tray is in the locked position, the second linkage is used to support the lifting frame.

[0007] Preferably, the elastic element is a spring, with one end of the spring fixedly connected to the ear seat fixing seat and the other end fixedly connected to the side of the second linkage rod near the first linkage rod.

[0008] Preferably, a limiting ring is provided at the position of the ear seat fixing base corresponding to the horizontal support link, the limiting ring is slidably engaged with the horizontal support link, a limiting slider is provided on the inner side wall of the limiting ring, and a limiting groove is provided on the horizontal support link at the position of the limiting slider, the limiting groove is slidably engaged with the limiting slider.

It employs an integrated mechanical structure combining an anti-fall linkage module and a lifting module. The battery tray presses against a follower wheel, driving the linkage rods, while elastic elements assist in resetting – a purely mechanical linkage that automatically triggers the anti-fall function without an external power source. Multiple follower wheels adapt to various conveying conditions, reducing conveying deviations. Multiple anti-fall linkage modules provide redundant protection, solving the significant safety hazards of existing battery production and testing equipment, preventing accidental tray falls, and significantly improving production safety. Furthermore, the clearance channel of the lifting frame ensures continuous conveying of the next battery tray, improving production efficiency. Attached Figure Description

[0019] The following is a reference appendix. Figure 1 To be continued Figure 3 This application describes a mechanical device for preventing an abnormal drop of a pallet.

[0020] Reference Figures 1 to 3 The mechanical device for preventing abnormal drop of the tray includes a frame 1. The frame 1 is equipped with a conveying module 2, a lifting module, a probe detection module 4 and an anti-drop linkage module 5. The conveying module 2 is used to horizontally convey the battery tray 6. The lifting module includes a lifting frame 3 and a lifting drive (not shown in the figure). The lifting frame 3 is used to support the battery tray 6 and is vertically slidably connected to the frame 1. The lifting drive is set on the frame 1 and is used to drive the lifting frame 3 to rise and fall. The probe detection module 4 is set on the frame 1 and located above the lifting module. There is a detection position on the sliding path of the lifting frame 3. When the lifting frame 3 is in the detection position, the probe detection module 4 is used to dock with the battery tray 6 on the lifting frame 3 to perform the battery detection process. There is a locking position on the conveying path of the battery tray 6. When the lifting frame 3 is in the detection position and the battery tray 6 is in the locking position, the anti-fall linkage module 5 is used to support the lifting frame 3. Specifically, the frame 1 serves as the supporting foundation, the conveying module 2 enables the horizontal conveying of the battery tray 6, and the lifting drive of the lifting module drives the vertically slidingly connected lifting frame 3 to lift the battery tray 6 to the detection position. Then, the probe detection module 4 connects with the battery in the battery tray 6 to complete the detection. When the lifting frame 3 is in the detection position and the battery tray 6 is subsequently conveyed to the locking position, the anti-fall linkage module 5 supports the lifting frame 3 to complete the anti-fall function of the tray 6. Thus, the functions of battery conveying, lifting detection and anti-fall protection are integrated to form a complete and safe operation process.

[0021] It should be noted that the probe detection module 4 uses a conventional probe detection structure available on the market, which will not be elaborated here. The conveying module 2 can use a conventional conveyor line to meet the continuous conveying requirements of the battery tray 6. For example, a roller conveyor line can be used, which drives the rollers to rotate through a motor transmission component to convey the tray 6. The load-bearing capacity is suitable for most specifications of battery trays 6, and the conveying is stable. It is also easy to coordinate with the lifting action of the lifting module. Chain plate conveyor lines, belt conveyor lines, etc. can also be used. Technicians can flexibly choose according to the weight, size and production cycle of the battery tray 6 in actual production. There are no restrictions here. Furthermore, the lifting drive can be a common type of drive available on the market, such as a pneumatic cylinder, hydraulic cylinder, electric cylinder, or ball screw mechanism, to achieve vertical and stable lifting of the lifting frame 3 and accurately lift the battery tray 6 to the detection position. Technicians can flexibly select the appropriate type based on factors such as the weight of the battery tray 6 and the lifting accuracy requirements, without any restrictions.

[0022] Preferably, in this embodiment, the anti-fall linkage module 5 includes a first linkage link 51, a second linkage link 52, a fixed ear seat 53, an ear seat fixing seat 54, and a horizontal support link 55. The length direction of the first linkage link 51 is the same as the conveying direction of the battery tray 6. A follower wheel 56 is rotatably mounted on the first linkage link 51. The follower wheel 56 is located on the conveying path of the battery tray 6 and is used to abut against the bottom of the battery tray 6. The ear seat fixing seat 54 is vertically fixedly installed on the frame 1, and the fixed ear seat 53 is fixedly installed on the ear seat fixing seat 54. The horizontal support link 55 is located on the lifting frame. 3. The bottom is slidably connected to the ear seat fixing seat 54. A sliding column 57 is provided on the side of the horizontal support link 55 near the fixed ear seat 53. One end of the second linkage link 52 is inclined towards the conveying direction of the battery tray 6 and is fixedly connected to the first linkage link 51. The other end of the second linkage link 52 is provided with a linkage sliding hole 58. The sliding column 57 and the linkage sliding hole 58 are slidably engaged. The second linkage link 52 is rotatably connected to the fixed ear seat 53 and an elastic element is provided between it and the ear seat fixing seat 54. The elastic element is used to continuously provide the second linkage link 52 with a pulling force opposite to the conveying direction of the battery tray 6. When the lifting frame 3 is in the detection position and the battery tray 6 is in the locked position, the second linkage 52 is used to support the lifting frame 3.

[0023] Specifically, the mechanical linkage structure of the anti-fall linkage module 5 works as follows: the follower wheel 56 on the first linkage link 51 is located on the conveying path of the battery tray 6. When the battery tray 6 enters the locked position, the bottom of the battery tray 6 abuts against the follower wheel 56 and drives the follower wheel 56 to drive the first linkage link 51 to move. The first linkage link 51 then drives the second linkage link 52 to rotate around the fixed lug 53. During this process, the elastic element is stretched and generates a pulling force opposite to the conveying direction of the tray 6. At the same time, the linkage sliding hole 58 of the second linkage link 52 forms a sliding engagement with the sliding column 57 of the horizontal support link 55, driving the horizontal support link 55 to slide and extend to the bottom of the lifting frame 3. When the lifting frame 3 is in the detection position, the extended horizontal support link 55 supports the lifting frame 3. By setting this purely mechanical linkage structure and cooperating with the conveying action of the battery tray 6 to trigger the anti-fall function, it is possible to achieve an automated response function without an additional power source, simplifying the structure, and with fast response speed and high structural reliability.

[0024] Preferably, the elastic element is a spring 59. One end of the spring 59 is fixedly connected to the ear seat fixing base 54 and the other end is fixedly connected to the side of the second linkage 52 near the first linkage 51. The spring 59 can provide a stable and controllable elastic driving force to the second linkage 52 through its elastic deformation. At the same time, the spring 59 has a simple structure, low cost, and long service life, making it suitable for this working condition.

[0025] Furthermore, a limiting ring 7 is provided on the ear seat fixing base 54 at the position corresponding to the horizontal support link 55. The limiting ring 7 is slidably engaged with the horizontal support link 55. A limiting slider (not shown in the figure) is provided on the inner side wall of the limiting ring 7. A limiting groove (not shown in the figure) is provided on the horizontal support link 55 at the position corresponding to the limiting slider. The limiting groove is slidably engaged with the limiting slider. By setting the limiting groove and the limiting slider, the sliding stroke of the horizontal support link 55 can be limited, avoiding its excessive extension or retraction that could cause it to disengage from the structure, thereby improving the stability of the movement of the horizontal support link 55.

[0026] Preferably, multiple follower wheels 56 are arranged along the first linkage 51, with the spacing between adjacent follower wheels 56 being smaller than the size of the battery tray 6. This ensures that when the battery tray 6 is transported to the locking position, regardless of any slight positional deviation in the transport path, its bottom can cover and press against at least two follower wheels 56. This ensures that the follower wheels 56 can effectively drive the first linkage 51 to move, thereby triggering subsequent anti-fall linkage actions. This expands the trigger coverage of the follower wheels 56 and avoids the problem of the anti-fall linkage module 5 being missed.

[0027] Preferably, multiple second linkage links 52 are provided, and multiple fixed lugs 53, lug fixing seats 54, and horizontal support links 55 are provided corresponding to the number of second linkage links 52. By providing multiple second linkage links 52, fixed lugs 53, lug fixing seats 54, and horizontal support links 55, a multi-position, distributed support structure can be constructed to distribute the weight load of the lifting frame 3 and the battery tray 6, avoid structural damage caused by excessive force on a single point of support, achieve redundant protection of multi-point synchronous support, and significantly improve the reliability of the anti-fall function.

[0028] Preferably, multiple sets of anti-fall linkage modules 5 are arranged. By setting multiple sets of anti-fall linkage modules 5, multiple sets of collaborative anti-fall redundancy structures can be constructed, expanding the coverage of anti-fall protection and further improving the reliability of the anti-fall function.

[0029] Preferably, the lifting frame 3 includes a lifting support frame 31, a vertical lifting rod 32, and a horizontal mounting rod 33. The lifting support frame 31 is used to place the battery tray 6 and is fixedly connected to the horizontal mounting rod 33 through the vertical lifting rod 32. The vertical lifting rod 32 passes vertically through and is slidably connected to the frame 1. The lifting support frame 31 and the horizontal mounting rod 33 are located on the upper and lower sides of the frame 1, respectively. When the lifting frame 3 is in the detection position, a clearance channel is formed between the lifting support frame 31 and the conveying module 2 for the battery tray 6 to pass through; When the lifting frame 3 is in the detection position and the battery tray 6 is in the locked position, the anti-fall linkage module 5 is used to support the horizontal mounting rod 33; Specifically, the lifting support frame 31 is fixedly connected to the horizontal mounting rod 33 via a vertical lifting rod 32. The vertical lifting rod 32 passes vertically through and is slidably connected to the frame 1, so that the lifting support frame 31 and the horizontal mounting rod 33 are located on the upper and lower sides of the frame 1, respectively. When the lifting frame 3 is in the detection position, a clearance channel is formed between the lifting support frame 31 and the conveying module 2, allowing the subsequent pallet 6 below to pass normally. At the same time, the anti-fall linkage module 5 indirectly achieves stable support for the entire lifting frame 3 and the pallet 6 by supporting the horizontal mounting rod 33. Through the structural design of the lifting frame 3, while ensuring that the lifting frame 3 can normally monitor the pallet 6 for detection, the clearance channel ensures the continuity of the conveyor line, and the support stability is improved by supporting the horizontal mounting rod 33. Thus, it meets the dual requirements of anti-fall protection function and continuous pallet 6 conveying function, and improves the space utilization of the equipment.

[0030] The implementation principle of the mechanical device for preventing abnormal drop of a pallet according to the embodiments of this application is as follows: During operation, the conveying module 2 first transports the tray 6 carrying the battery to the lifting area of ​​the lifting module. Then, the lifting drive is activated, driving the lifting frame 3 to move upward until the tray 6 is lifted to the preset detection position. At this time, the probe detection module 4 located above the lifting module connects with the battery in the tray 6, and starts and completes the detection process of battery electrical performance and other parameters. While the tray 6 is in the detection position, the conveying module 2 continues to operate to convey the subsequent battery tray 6. During the conveying of the subsequent tray 6, the bottom of the tray 6 will abut against the follower wheel 56 and press down against the follower wheel 56 with the conveying action, thereby driving the first linkage rod 51 to move synchronously. The movement of the first linkage rod 51 drives the second linkage rod 52 to rotate around the fixed ear seat 53. During this process, the spring 59 between the second linkage rod 52 and the ear seat fixed seat 54 is stretched. At the same time, the linkage sliding hole 58 on the second linkage rod 52 and the sliding column 57 of the horizontal support rod 55 form a sliding fit, pushing the horizontal support rod 55 to extend horizontally along the ear seat fixed seat 54 until the horizontal support rod 55 abuts against the horizontal mounting rod 33 of the lifting frame 3 in the detection position, thereby providing stable support for the lifting frame 3 and preventing it from falling abnormally due to malfunction. After the subsequent tray 6 completely leaves the locked position, the spring 59 releases its elastic potential energy, pulling the second linkage 52 to rotate in the opposite direction and reset, preparing for the next transport of the tray 6 and the anti-fall protection seat.

[0031] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the scope of protection of this application.
