Description

Technical Field

[0001] This article belongs to the technical field of PTC chip sorting machines, specifically involving a highly stable automated PTC chip sorting machine. Background Technology

[0002] The optimal temperature range for lithium-ion batteries is +20°C to +30°C. At low temperatures, lithium-ion batteries experience permanent capacity reduction due to lithium plating at the anode. At high temperatures, the active chemical substances may undergo irreversible reactions, thereby damaging the battery.

[0003] The main impacts are on cycle life, driving range, and charging time. Therefore, PTC assemblies are currently needed to heat lithium-ion batteries. The PTC assembly requires neatly arranged PTC wafers, necessitating a row-by-row arrangement of the wafers.

[0004] However, PTC wafers are typically too small and require extremely high precision, necessitating the use of specialized wafer sorting machines to arrange them sequentially on the electrode sheets. However, most existing wafer sorting machines simply use vacuum suction arms to pick up and arrange the wafers one by one, which easily leads to uneven arrangement and misalignment between PTC wafers. If a sorting mold is used before picking, then a single machine can only be used for one size of electrode sheet and PTC board, resulting in a significant increase in the cost of production equipment. Utility Model Content

[0005] To address the aforementioned issues, this paper proposes a highly stable automated PTC sheet stacking machine. The stacking machine is mounted on the surface of a frame and includes a carrier platform, a whole-row suction assembly, a sheet forming assembly, a single-sheet suction assembly, a hopper, and a vacuum connector frame. The carrier platform, whole-row suction assembly, sheet forming assembly, single-sheet suction assembly, and hopper are all horizontally parallel to each other. The carrier platform is horizontally positioned in the center of the upper surface of the frame. The whole-row suction assembly is horizontally positioned across the left and right sides above the carrier platform. The sheet forming assembly is horizontally positioned behind the whole-row suction assembly. The single-sheet suction assembly is positioned above and behind the sheet forming assembly, and the hopper is positioned below and behind the single-sheet suction assembly. The whole-row suction assembly includes double-row guide rails, a gantry frame, and whole-row suction heads. The sheet forming assembly includes a sheet conveyor belt and a sheet pusher. The single-sheet suction assembly includes a suction head moving frame and a single-sheet suction head assembly. The whole-row suction heads are horizontally aligned with the surface of the carrier platform. The electrode sheets are aligned longitudinally. A material-aligning push rod is provided on the outer side of the upper surface of the conveyor belt. The number of push rods is the same as the number of transverse electrode sheets on the carrier platform. The suction head shifting frame is longitudinally and vertically movable between the sheet material assembly and the hopper. A lifting mechanism is provided below the bottom of the hopper. A vacuum connector frame is provided horizontally above the row suction assembly, sheet material assembly, and single-piece suction assembly. This allows for precise arrangement of PTC elements according to set parameters and arrangement methods. After placement on the electrode sheets, the error should be controlled within ±0.1. A set of PTC elements is arranged in 30 seconds, demonstrating high arrangement efficiency to meet production needs. During long-term operation, it exhibits stable performance, low failure rate, and can work continuously for over 24 hours. After changing the carrier and hopper assembly and adjusting the parameters, it can adapt to the arrangement of PTC elements of different specifications and sizes. It features automatic suction and arrangement functions, reducing manual intervention.

[0006] The frame is a rectangular tabletop frame with protective supports at the four corners of the tabletop. An operation panel is located on the outer front of the protective supports. A recessed platform is horizontally parallel to the rear of the frame, and a material hopper is horizontally located in the center of the surface of the recessed platform. A lifting mechanism is located inside the recessed platform, which passes through the bottom of the material hopper and communicates with the inside of the hopper. By setting the frame with different heights at the front and rear, it is possible to conveniently set up the material hopper at the rear of the frame, making it easy to retrieve material from the top of the hopper.

[0007] The carrier platform is a rectangular groove-type carrier platform. The surface of the carrier platform is provided with several electrode plate positioning grooves arranged in a horizontal array. Electrode plates are placed in the electrode plate positioning grooves. The electrode plate positioning grooves are all parallel to the entire row of suction heads, the material conveyor belt, the single suction head group and the material bin. The electrode plate positioning grooves set on the surface of the carrier platform are all parallel to other mechanisms on the sheet stacking machine, thereby facilitating the subsequent material handling and retrieval operations during the sheet stacking process.

[0008] Double-row guide rails are arranged longitudinally parallel to each other on the left and right sides of the carrier platform. A gantry frame is arranged horizontally above the double-row guide rails. One end of the gantry frame is connected to the double-row guide rails through a gear and rack transmission mechanism, and the other end of the gantry frame is connected to the double-row guide rails through a sliding rail slider. A row of suction heads is arranged below the gantry frame. The row of suction heads is connected to the gantry frame through a vertical displacement cylinder. The double-row gantry frame can stably and accurately pick up and place PTC sheets on the carrier platform, and the gear and rack mechanism can also achieve precise displacement and positioning.

[0009] The material conveyor belt is a limiting-type material transfer conveyor belt. Both the front and rear sides of the upper surface of the material conveyor belt are equipped with side guards. The spacing between the side guards is the same as the width of the PTC sheet. A material pusher is located on the outer front side of the material conveyor belt. The shape of the material pusher is a bent rod with one end horizontally positioned above the upper surface of the material conveyor belt, and the other end is connected to a transverse cylinder. The material conveyor belt allows for the batch assembly of originally dispersed electrode sheets into a single PTC sheet strip of equal length, which is then pushed and limited by the material pusher, facilitating subsequent suction by the entire row of suction heads.

[0010] The suction head shifter is fixedly located at the bottom center of the vacuum connector frame. The suction head shifter is longitudinally connected to the single suction head assembly via a cylinder. The single suction head assembly consists of several single suction heads combined together. Each single suction head assembly is equipped with a vertical displacement cylinder. The position of each single suction head corresponds one-to-one with the position of the PTC sheet on the upper surface of the hopper. By separating the single suction head assemblies, it is convenient to remove the PTC sheets that were originally stacked separately in the hopper together, which facilitates the displacement operation.

[0011] The hopper is a top-discharge type. The upper surface of the hopper has several horizontally spaced picking ports. The interior of the hopper has several PTC sheets stacked vertically. The bottom of the hopper is connected to the lifting mechanism through the surface of the frame. Through the top-discharge hopper and the lifting mechanism, the hopper can be stably and efficiently picked up one by one from the top surface and then ejected.

[0012] The vacuum connector frame is a tube arrangement frame. Both ends of the vacuum connector frame are suspended above the whole row suction assembly, the sheet material assembly, and the single sheet suction assembly via columns. Both sides of the vacuum connector frame are equipped with the same number of suction heads as the whole row suction assembly and the single sheet suction assembly. The vacuum connector frame not only facilitates the arrangement and docking of the vacuum pipes required by the sheet stacking machine, but also facilitates the setting of suction head moving frames, which is convenient for the displacement of the entire single sheet suction assembly.

[0013] Beneficial effects:

[0014] Arrangement accuracy: The PTC elements should be arranged precisely according to the set parameters and arrangement method, and the error should be controlled within ±0.1 after being placed on the electrode sheet.

[0015] Arrangement speed: It takes 30 seconds to arrange a set of PTC wafers (10 heating elements), which has high arrangement efficiency to meet production needs.

[0016] Stability: The system exhibits stable performance and a low failure rate during extended operation, capable of continuous operation for over 24 hours.

[0017] Compatibility: After changing the carrier and hopper components, and adjusting the parameters, it can adapt to PTC element arrangement of different specifications and sizes.

[0018] Automation level: Equipped with automatic pick-up and film arrangement functions, reducing manual intervention; Ease of operation: Features a user-friendly human-machine interface, making operation simple and easy to understand, facilitating parameter setting and adjustment by operators; Ease of cleaning and maintenance: Easy to perform daily cleaning and regular maintenance, reducing maintenance costs and time; Safety: Equipped with comprehensive safety protection devices, such as emergency stop buttons and protective doors, to ensure the safety of operators.

[0019] By setting up frames with different heights at the front and back, it is easy to set up a hopper at the rear of the frame, making it convenient to retrieve materials from the top of the hopper.

[0020] The electrode positioning grooves on the surface of the carrier platform are all parallel to other mechanisms on the sheet stacking machine, which facilitates the material handling and retrieval operations during the subsequent sheet stacking process.

[0021] The double-row gantry frame design allows for stable and accurate placement and loading of PTC wafers onto the platform, while the rack and pinion mechanism enables precise displacement and positioning.

[0022] The material conveyor belt can combine the originally scattered electrode sheets into batches as needed to form a PTC strip with the same length of electrode sheets. Then, the material pusher rod is used to push and limit the strip, which facilitates the subsequent suction of the entire row of suction heads.

[0023] The separate suction head assembly allows for easy removal of PTC tablets that were originally stacked separately in the hopper, facilitating relocation operations.

[0024] The vacuum connector bracket not only facilitates the arrangement and connection of vacuum pipes required by the wafer sorting machine, but also makes it easy to set up a suction head moving bracket, which facilitates the displacement of the entire single-wafer suction assembly.
