Description

Technical Field

[0001] This utility model relates to a lead ingot processing and surface treatment device, and particularly to a lead ingot surface burr removal device. Background Technology

[0002] In the production process of lead-acid batteries, companies can recycle and dismantle waste lead-acid batteries, extract lead from the electrode plates, and melt and cast them into lead ingots to provide raw materials for the production of new electrode plates. However, after the lead ingots are cast and demolded, burrs often remain on the surface. These burrs not only affect the appearance quality of the lead ingots but may also cause problems in subsequent processing, such as causing jamming or damage to processing equipment, affecting the continuity of production. During the use of lead ingots, the burrs on the surface of the lead ingots will also reduce the precision and reliability of processing and assembly, leading to poor fit. Operators need to clean the burrs on the surface of the lead ingots before processing lead-acid batteries.

[0003] In the existing process of deburring the surface of lead ingots, manual cleaning is usually carried out using cleaning tools such as scrapers to manually remove the burrs on the top surface of the lead ingots. Manual cleaning is labor-intensive, has low cleaning efficiency, and is prone to incomplete cleaning, which affects the production efficiency of lead-acid battery electrode plates. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a lead ingot surface burr cleaning device. After the infrared sensor senses the lead ingot being transported on the top roller conveyor chain, the limiting device limits the position of the lead ingot, the lifting device controls the scraper to descend to the top surface of one end of the lead ingot, the displacement device controls the scraper to scrape across the top surface of the lead ingot, the positioning component provides buffering and adaptive height and angle adjustment during the movement of the scraper, the baffle connected to the side of the scraper and the scraper itself collect the scraped burrs and other materials during the cleaning process, after the scraper moves past the other end of the top surface of the lead ingot, the scraped excess lead material falls into the recycling position for recycling, effectively improving the quality and efficiency of lead ingot surface cleaning and the recycling efficiency of waste materials, improving production efficiency and reducing production costs.

[0005] This utility model is achieved through the following technical solution:

[0006] A burr removal device for lead ingot surfaces includes a frame, a conveyor chain, and a drive unit. The conveyor chain is connected to the top surfaces of both sides of the frame, and the drive unit is connected to the inner bottom surface of the frame. The rotation shaft of the drive unit is connected to the input shaft of the conveyor chain. A limit device is connected to the inner bottom surface of the frame next to the drive unit. An infrared sensor is connected between the limit device and the top of the frame between the starting end of the conveyor chain and the limit device via a connecting rod. A bracket is connected to the top surface of the frame above the limit device. A second lifting device is connected to one side of the bracket. A displacement device is connected to the top surface of the output end of the second lifting device. A positioning element perpendicular to the top surface of the frame is connected to the output end of the displacement device. A scraper is connected to the end of the positioning element. A recovery position is connected to the top surface of the frame next to the conveyor chain below the tail end of the displacement device.

[0007] Furthermore, the conveyor chain is a top-mounted roller conveyor chain, the distance between the inner sides of the two conveyor chains is equal to the maximum side length of the lower half of the lead ingot, and the distance between the outer sides of the two conveyor chains is equal to the length of the top surface of the lead ingot.

[0008] Furthermore, the drive device is a motor, the rotating shaft of the drive device and the input shaft of the conveyor chain are parallel to each other and connected by sprockets in opposite positions, and the rotating shaft of the drive device and the input shaft of the conveyor chain are hinged to the sprockets through a transmission chain.

[0009] Furthermore, the limiting device includes a lifting device and a baffle. The lifting device is a cylinder. The telescopic rod of the lifting device is perpendicular to the top surface of the frame. The baffle is connected to the end of the telescopic rod of the lifting device. The top of the baffle is connected to a roller whose circumferential side is parallel to the inner side of the frame. When the telescopic rod of the lifting device extends to its maximum distance, the top of the roller is on the same horizontal plane as the top surface of the frame.

[0010] Furthermore, the support frame is an inverted U-shaped structure perpendicular to the conveyor chain, and the second lifting device is a slide cylinder. The second lifting device is connected to the side of the support frame opposite to the output end of the limiting device.

[0011] Furthermore, the displacement device is an electric lead screw slide module. The lead screw of the displacement device is parallel to both ends of the frame and is directly opposite the conveyor chain in the vertical direction. The length of the lead screw is greater than the length of the top surface of the lead ingot and less than the width of the top surface of the frame.

[0012] Furthermore, the positioning component includes a pair of buffer components and a rotating block. The buffer components are connected to the top surface of the output end of the displacement device. The buffer components are perpendicular to the top surface of the frame in the vertical direction, and the lower half of the buffer components is connected to a spring buffer structure. The rotating block has an L-shaped structure. The connection node of the two rods of the rotating block is rotatably connected to the bottom end of the buffer component. The ends of the two rods of the rotating block are respectively rotatably connected to two wheels, a front wheel and a rear wheel. The rear wheel is a wheel that is closer to the screw power input end of the displacement device in the horizontal direction.

[0013] Furthermore, the scraper has an inverted U-shaped structure and is connected to the bottom of the rotating block between the front and rear wheels. The scraper is deflected ten degrees relative to the vertical direction towards the rear wheel with its bottom edge as the axis. The inner side of the scraper is the cutting edge. The bottom inner cutting edge of the scraper is parallel to the conveyor chain and its length is equal to the width of the top surface of the lead ingot. The bottom inner cutting edge of the scraper is on the same horizontal plane as the bottom ends of the front and rear wheels. When the slider of the displacement device is at the starting end of the lead screw, the cutting edge of the scraper is vertically facing the outer side of the conveyor chain. When the slider of the displacement device is at the end of the lead screw, the bottom end of the rear wheel is vertically facing the outer side of the conveyor chain at the other end.

[0014] Furthermore, an L-shaped baffle is vertically connected to the bottom corners of the two ends of the bottom side of the scraper facing the tail end of the displacement device. The horizontal length of the baffle is equal to the length of the bottom edge of the scraper at both ends, and the vertical length of the baffle is greater than the length of the inner side of the scraper relative to the cutting edge and less than the side length of the scraper.

[0015] Furthermore, the horizontal center line of the recovery position coincides with that of the scraper in the vertical direction, the top surface height of the recovery position is equal to the top surface height of the conveyor chain, and the length of the side of the inner top surface of the recovery position that is close to the conveyor chain is equal to the length of the scraper.

[0016] Compared with the prior art, this utility model has the following obvious advantages:

[0017] I. In this utility model, the conveyor chain is a top-mounted roller conveyor chain. The distance between the inner sides of the conveyor chain connected to the top of the two side frames is equal to the maximum side length of the lower half of the lead ingot. During the transmission process, the position of the lead ingot in the horizontal direction perpendicular to the direction of the conveyor chain can be limited. An infrared sensor is connected between the top of the frame and the starting end of the conveyor chain. After the infrared sensor detects the lead ingot, the PLC system used with the device controls the lifting device of the limiting device to extend the telescopic rod. The baffle connected to the end of the telescopic rod limits the position of the lead ingot in the transmission direction, accurately limiting the lead ingot that is about to pass through the support.

[0018] Second, this utility model has a lifting device 2 connected to one side of the support, with the output end perpendicular to the top surface of the frame. The output end of the lifting device 2 is connected to a displacement device with a lead screw parallel to both ends of the frame. After the lead ingot is limited, the PLC system used with the device can control the position of the lifting device 2 and the displacement device to move the output end, thereby controlling the scraper to scrape on the top surface of the lead ingot. This optimizes manual operation and improves the automation level of scraping burrs off lead ingots.

[0019] Third, this utility model has a positioning key connected to the slider of the displacement device. The positioning key is connected to a spring buffer structure and a rotatable wheel assembly. The scraper is connected to the end of the positioning key between the rollers. When the scraper descends to the top surface of the lead ingot and moves horizontally, the positioning component can achieve adaptive adjustment of the scraper height and angle through the spring buffer and the rotation of the wheel assembly, ensuring complete cleaning of the burrs on the top surface and four sides of the top surface of the lead ingot, and improving the quality of deburring the lead ingot.

[0020] IV. In this utility model, baffles are vertically connected to both ends of the bottom side of the scraper facing the tail end of the displacement device. When the scraper scrapes over the top surface of the lead ingot, the scraped-off burrs and other lead materials accumulate and collect on the scraper and baffles on the top surface. After the scraper finishes scraping the top surface of the lead ingot, it leaves the top surface of the lead ingot during the displacement process. The spring buffer structure connected to the positioning component pushes the rotating block connected to the scraper to rotate. The burrs and other lead materials collected on the scraper are poured into the recycling position connected to the top surface of the frame on one side of the conveyor chain, thereby improving the recovery rate of scraped-off lead materials and reducing production costs.

The buffer component 901 is perpendicular to the top surface of the frame 1 and connected to the top surface of the output end of the displacement device 8. The lower half of the buffer component 901 is connected to a spring buffer structure in the vertical direction. The rotating block 902 has an L-shaped structure. The connection node of the two rods of the rotating block 902 is rotatably connected to the bottom end of the buffer component 901. The ends of the two rods of the rotating block 902 are respectively rotatably connected to wheels with sides parallel to both ends of the frame 1. The wheel closer to the screw power input end of the displacement device 8 in the horizontal direction is the rear wheel 903, and the wheel closer to the tail end of the displacement device 8 is the front wheel 904.

[0030] The scraper 10 is an inverted U-shaped structure at the bottom of the rotating block 902 connected between the front wheel 904 and the rear wheel 903. The scraper 10 is vertically oriented towards the rear wheel 903, deflected by ten degrees around its bottom edge. The inner side of the scraper 10 is the cutting edge.

The bottom inner cutting edge of the scraper 10 is on the same horizontal plane as the bottom ends of the front wheel 904 and the rear wheel 903. When the slider of the displacement device 8 is at the starting position of the lead screw, the bottom inner cutting edge of the scraper 10 is vertically facing the outer side of the conveyor chain 2. When the slider of the displacement device 8 moves to the end position of the lead screw, the bottom end of the rear wheel 903 is vertically facing the other... On the outer side of one end of the conveyor chain 2, the scraper 10 has an L-shaped baffle vertically connected to the bottom corners of the two ends of the side facing the tail end of the displacement device 8. The horizontal length of the baffle is equal to the length of the bottom edge of the scraper 10 at both ends. The vertical length of the baffle is greater than the length of the inner side of the scraper 10 relative to the cutting edge and less than the side length of the scraper 10. The recovery position 11 is connected to the top surface of the frame 1 next to the side of the conveyor chain 2 below the tail end of the displacement device 8. The horizontal center line of the recovery position 11 coincides with the horizontal center line of the scraper 10 in the vertical direction. The top surface of the recovery position 11 is on the same horizontal plane as the top surface of the conveyor chain 2. The length of the side of the inner top surface of the recovery position 11 close to the conveyor chain 2 is equal to the length of the scraper 10.

[0031] The working principle of this utility model is as follows:

[0032] This utility model is used in conjunction with a PLC controller.

[0033] When using this utility model, the operator turns on the PLC controller and the various devices connected to the device, drives the rotating shaft of the drive device 3 to rotate, drives the input shaft of the conveyor chain 2 which is hinged through the transmission chain to rotate, and the conveyor chain 2 starts to transport. The lead ingot 12 after casting and demolding enters the conveyor chain 2 of the burr cleaning device from the conveyor chain of the previous process. The bottom two ends of the lead ingot 12 are limited by the conveyor chain 2. When the lead ingot 12 is transported to a position close to the lower part of the displacement device 8, it is sensed by the infrared sensor 4 connected to the inner side of the top of the frame 1. After the PLC controller receives the signal that the lead ingot 12 has passed, it controls the lifting device 501 to drive the telescopic rod to extend to the maximum distance. When the lead ingot 12 is transported to a position in front of the lifting device 501, it is blocked by the baffle 502, thus completing the limitation of the horizontal position of the lead ingot 12.

[0034] After the position of lead ingot 12 is defined, the PLC controller controls the lifting device 2 7 to drive the output end to descend. The displacement device 8 connected to the output end of the lifting device 2 7 also descends accordingly. The descent distance is equal to the vertical distance from the inner bottom edge of the scraper 10 to the center point of the top surface of the lead ingot 12 in the initial state. After the descent is completed, the spring connected to the buffer 901 is in a compressed state, and the cutting edge of the scraper 10 is in close contact with one end of the top surface of the lead ingot 12 and the two sides parallel to both ends of the frame 1. The PLC controller controls the displacement device. 8 drives the slider to move, and the front wheel 904 and the rear wheel 903 support and limit the scraper 10 to scrape over the top surface of the lead ingot 12. During the movement of the scraper 10, the positioning member 9 is buffered by the spring of the buffer member 901 and the rotating block 902 rotates the wheel assembly to support the scraper 10 to adaptively adjust the height and angle on the top surface of the lead ingot 12, so as to ensure that the burrs on the top surface of the lead ingot with different top surface structures are completely cleaned. The scraped burrs and other lead materials accumulate on one side of the scraper 10 and the baffle connected to the scraper 10, and are carried and pushed by the scraper 10 together.

[0035] As the scraper 10 moves from one end of the top surface of the lead ingot 12 to the other, the slider of the displacement device 8 moves to the tail end of the displacement device 8. The front wheel 904 and the scraper 10 slide out of the top surface of the lead ingot 12, and the rear wheel 903 presses against the top surface of the lead ingot 12 near the side. The rotating block 902 rotates towards the power input end of the lead screw of the displacement device 8 under the push of the spring buffer structure connected to the buffer 901. The scraper 10 rotates with the rotating block 902. The scraped burrs and other lead materials fall into the recycling position 11 connected to the top of the frame 1 on the side of the conveyor chain 2 during the process of the scraper 10 sliding out of the top surface of the lead ingot 12 and rotating. After the burr cleaning is completed, the PLC controller controls the lifting device 2 7, the displacement device 8 and the limit device 5 to reset in sequence. The lead ingot 12 with the burr cleaned continues to be transported to the next process.

They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
