Description

Technical Field

[0001] This utility model belongs to the technical field of automated processing equipment, specifically relating to a device for removing paint from end buttons and nuts. Background Technology

[0002] Terminal plugs are common electrical connection components widely used in battery packs, power equipment, and other fields. During their manufacturing or repair, nuts are usually installed on the threaded parts of the terminal plug for purposes such as testing, transportation, anti-loosening, or marking, and paint is usually applied to the surface of the terminal plug for marking.

[0003] When end buttons need to proceed to the next process (such as welding or assembly) or undergo rework, the original nuts and paint markings must be removed first. Currently, the industry generally adopts a step-by-step approach to removing nuts and paint from end button workpieces: first, the nuts are unscrewed or ejected from the end button manually or with special fixtures; then, the workpiece is transferred to another station, where the paint layer in the designated area is removed using grinding, scraping, or milling equipment.

[0004] This segmented processing mode has obvious drawbacks: on the one hand, the workpiece needs to be repositioned and transported between two independent processes, which not only increases labor costs but also easily causes positioning deviations and affects processing consistency; on the other hand, the waiting and transfer between processes significantly prolong the overall production cycle and reduce the level of automation and production efficiency of the production line. Utility Model Content

[0005] This invention addresses the aforementioned problems in the existing technology by proposing a device that can complete the removal of paint from the end knob and the removal of the nut in one process.

[0006] This utility model can be achieved through the following technical solutions:

[0007] A device for removing paint from end caps and nuts, comprising:

[0008] The frame is equipped with a lifting platform;

[0018] As a further improvement of this utility model, the drive unit is configured as a drive motor and is disposed on the side of the assembly plate. The drive motor is connected to each of the power heads via a synchronous belt.

[0019] As a further improvement of this utility model, the bottom of the product placement plate is provided with a base, which consists of a base plate and supports located on both sides of the base plate, and a cavity is formed between the base plate and the two supports.

[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0037] like Figures 1-3 As shown, this utility model provides a device for removing paint from end buttons and nuts, comprising:

[0038] The frame is equipped with a lifting platform 100.

[0039] The product placement plate 200 is located at the bottom of the lifting plate 100, and the product placement plate 200 has several product mounting slots 210.

[0040] Mounting plate 300 is connected to the bottom of lifting plate 100 and located on top of product placement plate 200. Mounting plate 300 moves synchronously with the movement of lifting plate 100.

[0041] Push rod 310, which is set at the bottom of mounting plate 300 and used to push the nut on workpiece 500 downward;

[0042] The milling cutter assembly is located at the bottom of the mounting plate 300. The milling cutter assembly includes a drive unit and a milling cutter 320 that is driven to rotate by the drive unit. The milling cutter 320 is used to remove paint from the surface of the workpiece 500.

[0043] In use, multiple end button workpieces 500 to be processed are respectively placed into the product mounting slots 210 on the product placement plate 200 for positioning. Then, the frame drives the lifting plate 100 to descend, which drives the mounting plate 300, the push rod 310 and the milling cutter assembly to descend synchronously.

[0044] During the descent, the push rod 310 abuts against the nut on the workpiece 500 and pushes it downward to achieve unloading. At the same time, the milling cutter 320 first contacts the surface of the workpiece 500 and rotates at high speed to mill and remove the paint layer in the designated area. The entire process completes the two processes of paint removal and nut removal in one lifting action, without the need for intermediate transfer or reclamping.

[0045] Compared with the prior art, the device provided in this embodiment has at least the following advantages:

[0046] 1. Integrated operation: The paint removal and nut removal processes are integrated into the same device and station, avoiding the secondary handling and repositioning caused by the step-by-step operation in the traditional process, and significantly improving the processing efficiency;

[0047] 2. High consistency and precision: Since the two processes are completed simultaneously, the workpiece 500 does not need to be disassembled and re-clamped, which effectively ensures the consistency of the processing position and improves the stability of product quality;

[0048] 3. Suitable for batch processing: The product placement plate 200 is equipped with multiple mounting slots 210, which, together with the corresponding push rods 310 and milling cutters 320, can realize the simultaneous processing of multiple workpieces 500, meeting the needs of batch production.

[0049] Preferably, a vertically arranged cylinder 110 is installed on the top of the frame, and the lifting plate 100 is connected to the cylinder shaft of the cylinder 110. The lifting plate 100 is driven to rise and fall by the cylinder 110, which in turn drives the mounting plate 300 to rise and fall synchronously, thereby realizing the position adjustment of the push rod 310 and the milling cutter 320.

[0050] This pneumatic drive system is simple in structure, responds quickly, and is reliable in control. It can precisely control the lifting stroke and force, ensuring that the push rod 310 applies appropriate thrust when pushing out the nut, while the milling cutter 320 makes smooth contact with the surface of the workpiece 500 to remove paint, avoiding damage to the workpiece 500 due to excessive impact or incomplete paint removal due to insufficient pressure.

[0051] Preferably, the product mounting slots 210 are arranged in at least one row on the product placement plate 200, with each push rod 310 and milling cutter 320 corresponding to each product mounting slot 210. This layout ensures that each station is equipped with an independent ejection and paint removal mechanism, so that in one lifting action, all the end button workpieces 500 in the product mounting slots 210 can simultaneously complete the nut ejection and surface paint removal operations without having to process or adjust their positions one by one.

[0052] The multi-station parallel processing design significantly improves the processing efficiency of a single operation, making it suitable for batch production scenarios. At the same time, the one-to-one correspondence structure ensures consistent processing conditions at each station, improving the uniformity of product processing and yield.

[0053] Preferably, the milling cutter assembly further includes:

[0054] The assembly plate 330 is connected to the mounting plate 300;

[0055] The power head 321 is vertically mounted on the assembly plate 330, and the milling cutter 320 is mounted on the power head 321;

[0056] The drive unit is configured as a drive motor 331, which is located on the side of the assembly plate 330. The drive motor 331 is connected to each power head 321 via a synchronous belt 332.

[0057] This structure achieves synchronous rotation of multiple milling cutters 320 by centrally mounting multiple power heads 321 on a main assembly plate 330 and uniformly driving them via a synchronous belt 332 from a single drive motor 331. The synchronous belt 332 drive has the advantages of smooth transmission, low noise, simple maintenance, and can effectively ensure that the rotation speed of each milling cutter 320 is consistent, avoiding the problem of uneven paint removal effect caused by the difference in rotation speed.

[0058] The layout of a single motor with a synchronous belt 332 driving multiple power heads 321 not only simplifies the drive system structure and reduces equipment cost and space occupation, but also ensures the high synchronization and stability of milling actions at each station, improves the consistency of paint removal quality, and facilitates installation, commissioning and subsequent maintenance, which is conducive to the efficient and reliable operation of the equipment in mass production.

[0059] Preferably, the bottom of the product placement plate 200 is provided with a base 400, which consists of a base plate and supports located on both sides of the base plate, forming a cavity between the base plate and the two supports.

[0060] Furthermore, the product mounting slot 210 has a first clearance slot 211, and the bottom plate has a second clearance slot 410. The first clearance slot 211 and the second clearance slot 410 are arranged vertically and connected, and the second clearance slot 410 is connected to the cavity. Thus, the nut pushed downward from the end button by the push rod 310 can automatically fall into the cavity from the first clearance slot 211 and the second clearance slot 410 for collection.

[0061] In other words, by setting the first clearance groove 211 and the second clearance groove 410 that run vertically through the product mounting groove 210 and the base plate respectively, a smooth nut falling channel is formed, so that the ejected nuts can automatically fall into the cavity and be collected in a concentrated manner, avoiding the nuts from being scattered on the surface of the equipment or stuck in the work station. This not only simplifies the cleaning process and prevents foreign objects from interfering with subsequent processing, but also improves the safety of equipment operation and continuous operation capability, while providing structural support for realizing unmanned and automated production.

[0062] Preferably, the bottom of the base plate is provided with a guide plate 420, which is inclined toward the opening end of the cavity. The guide plate 420 is located at the end of the nut's falling path. Its inclined structure can guide the nut falling from the second clearance groove 410, so that it can slide more smoothly into the cavity and concentrate toward the opening end.

[0063] By setting an inclined guide plate 420, the nuts are effectively prevented from accumulating, getting stuck, or rebounding in the cavity, ensuring that the detached nuts are quickly and orderly collected in the designated area for easy subsequent unified cleaning or automatic discharge; at the same time, the reliability and automation level of the device during continuous operation are further improved, the frequency of manual intervention is reduced, and the overall work efficiency is improved.

[0064] Preferably, the first clearance groove 211 is opened along the length direction of the product mounting groove 210, and the second clearance groove 410 is perpendicular to the direction of the first clearance groove 211. Thus, at the bottom of a row of product mounting grooves 210, only one horizontally penetrating second clearance groove 410 needs to be opened to connect with all the corresponding first clearance grooves 211.

[0065] By setting the first clearance groove 211 laterally along the product mounting groove 210 and making the second clearance groove 410 longitudinally run through the entire row of workstations, the structural design and processing technology of the base plate are significantly simplified, avoiding the complexity of opening an independent drop channel for each workstation. At the same time, this layout effectively reduces the number of grooves and material weakening while ensuring that the nuts fall smoothly, improving the structural strength and manufacturing efficiency of the base 400, which is conducive to the mass production and long-term stable operation of the device.
