Description

Technical Field

[0001] This utility model relates to the field of anode plate welding, and in particular to a double anode plate sliding welding mechanism. Background Technology

[0002] In electrostatic precipitators used in the environmental protection industry, the anode plate is the core component. A high-voltage electric field is formed between the cathode wire connected to the high-voltage DC power supply and the grounded anode plate. Due to the corona discharge at the cathode, the gas is ionized. The negatively charged gas ions move towards the anode plate under the action of the electric field. During their movement, they collide with dust particles, causing the dust particles to become negatively charged. The charged dust particles also move towards the anode under the action of the electric field. Upon reaching the anode, they release their negative charge and are deposited on the anode plate. The purified gas is then discharged outside the dust collector.

[0003] Currently, the structure of the anode plate is mainly as follows: Figure 7 The single anode plate shown is relatively thin and has grooves on its surface, a common anode plate structure in the dust removal industry. However, for large dust collectors, to ensure better dust removal efficiency, a single anode plate with a length of up to 15m is required. This longer and thinner single anode plate is prone to shaking and has poor wind resistance in actual use. Therefore, in the dust removal industry, two single anode plates are stacked, i.e., an inverted anode plate is placed on top of a normally upright anode plate. (See [reference]). Figure 8 After stacking the two anode plates, spot weld them along the length near the end where they meet. See [link to spot weld location]. Figure 8 The dotted coil position, after welding, forms a double-windproof trench-type dust-suppressing anode plate. Currently, anode plate welding is mainly done manually, welding one point at a time. Due to the long length of the anode plate, several points need to be welded along the length direction. Therefore, manual welding is extremely inefficient, the welding process is unstable, product quality is difficult to guarantee, the labor intensity of workers is high, and the production cost is high, which can no longer meet the needs of modern mass production. To solve this problem, the applicant proposes a double anode plate sliding welding mechanism that can realize automatic welding of double anode plates, by using a medium-frequency welding machine to perform interval spot welding along the length direction of the anode plate. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a double anode plate sliding welding mechanism, including a welding base frame. A plate support frame for placing the anode plate is arranged on the upper surface of the welding base frame along the length of the anode plate. The width of the plate support frame is smaller than the width of the web of the anode plate. When the anode plate is placed on the plate support frame, the welding areas at both ends of the anode plate extend beyond the plate support frame, leaving welding electrode space on both sides. End positioning devices are respectively provided at the front and rear ends of the plate support frame. Side positioning devices are spaced apart on the left and right sides of the plate support frame along the length of the anode plate. The side positioning devices are installed by lifting and lowering a lifting and avoiding device. Medium-frequency welding machines are respectively provided on the left and right sides of the plate support frame. The medium-frequency welding machines are slidably installed along the length of the anode plate via a longitudinal sliding device. The upper welding electrode of the medium-frequency welding machine extends through the welding electrode space to the end welding area on the upper surface of the forward anode plate, and the lower welding electrode of the medium-frequency welding machine extends through the welding electrode space to the end welding area on the lower surface of the inverted anode plate.

[0005] As a preferred technical solution, the end positioning device includes end positioning cylinders disposed at the front and rear ends of the plate support frame. The end positioning cylinders are horizontally arranged, and the telescopic ends of the end positioning cylinders are arranged facing the front and rear ends of the anode plates. An end positioning plate is fixedly installed on the telescopic ends. The height of the end positioning plate corresponds to the height of the two stacked anode plates, and the width of the end positioning plate corresponds to the middle of the anode plates to avoid the upper welding electrode and the lower welding electrode.

[0006] As a preferred technical solution, the lifting and avoidance device includes a vertically arranged lifting and avoidance cylinder. The cylinder body of the lifting and avoidance cylinder is fixed on the welding base frame, and the side positioning device is fixed to the cylinder rod end of the lifting and avoidance cylinder. The lifting and avoidance cylinder can drive the side positioning device to descend and avoid the moving medium frequency welding machine.

[0007] As a preferred technical solution, the side positioning device includes a side positioning cylinder fixed to the lifting and avoiding cylinder. The side positioning cylinder is horizontally arranged, and the telescopic end of the side positioning cylinder is arranged facing the side end of the two stacked anode plates. A side positioning plate is fixedly installed on the telescopic end, and the height of the side positioning plate is the same as the height of the two stacked anode plates.

[0008] As a preferred technical solution, the welding base is provided with a longitudinal slide rail along the length of the anode plate, the bottom of the base of the medium frequency welding machine is fixed with a longitudinal slide block that is slidably installed along the longitudinal slide rail, the welding base is fixed with a longitudinal gear rail, and the base of the medium frequency welding machine is equipped with a sliding gear and a sliding drive motor that drives the sliding gear to rotate, and the sliding gear meshes with the longitudinal gear rail for transmission.

[0009] As a preferred technical solution, the medium frequency welding machine includes a body, on which an upper cantilever and a lower cantilever are provided. The upper welding electrode is installed at the bottom end of the upper cantilever, and the lower welding electrode is installed at the top end of the lower cantilever. The upper welding electrode and the lower welding electrode are positioned opposite each other vertically, and the distance between them is greater than the thickness between the welding areas at the ends of the stacked double anode plates.

[0010] Due to the adoption of the above technical solution, the beneficial effects of this utility model are: the device also moves along the length of the anode plate to realize automatic interval spot welding of the anode plate, complete the automatic welding of double anode plates, its front-to-back and left-to-right positioning is accurate, the welding quality is stable, the production efficiency is high, it can realize large-scale automatic production, and it is well applicable to the automated processing of long and thin plates, filling the gap in the industry.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0022] like Figure 1 and Figure 2As shown, the double anode plate sliding welding mechanism includes a welding base frame 10. A plate support frame 20 for placing the anode plate is arranged on the upper surface of the welding base frame 10 along the length of the anode plate. The plate support frame 20 is higher than the welding base frame 10, and its width is less than the width of the web of the anode plate. When the anode plate is placed on the plate support frame 20, the welding areas at both ends of the anode plate extend beyond the plate support frame 20, leaving space for welding electrodes on both sides. End positioning devices 30 are respectively provided at the front and rear ends of the plate support frame 20, and on the left and right sides of the plate support frame 20... Side positioning devices 40 are provided at intervals along the length of the anode plate. The side positioning devices 40 are installed by lifting and avoiding devices 50. Medium frequency welding machines 60 are provided on the left and right sides of the plate support frame 20. The medium frequency welding machines 60 are slidably installed along the length of the anode plate by longitudinal sliding devices 70. The upper welding electrode 61 of the medium frequency welding machine 60 extends through the welding electrode space to the end welding area on the upper surface of the positive anode plate. The lower welding electrode 62 of the medium frequency welding machine 60 extends through the welding electrode space to the end welding area on the lower surface of the inverted anode plate. Before welding, the inverted anode plate is first placed on the plate support frame 20, and then the upright anode plate is stacked on top of the inverted anode plate. Next, the end positioning devices 30 at both ends align the front and rear ends of the two anode plates. Simultaneously, the lifting and clearance devices 50 on both sides rise, so that the side positioning devices 40 face the two sides of the two anode plates, and both side positioning devices 40 extend and abut against the two sides of the two anode plates, aligning the left and right sides of the two anode plates. After alignment, the end welding area of ​​the two anode plates extends beyond the plate support frame 20, reserving space for welding. Before welding, the medium-frequency welding machine 60 needs to be adjusted so that the positions of the upper welding electrode 61 and the lower welding electrode 62 correspond to the end welding portion of the anode plate. Then, the longitudinal sliding device 70 moves towards the end of the anode plate, causing the upper welding electrode 61 to move above the upright anode plate. The lower welding electrode 62 is moved to the underside of the inverted anode plate, and the electrode welding distance is adjusted so that the distance between the electrode and the surface of the anode plate meets the welding requirements of 1mm-2mm. During welding, the longitudinal sliding device 70 drives the medium frequency welding machine 60 to move along the length direction of the anode plate. After moving a certain distance, it stops to perform spot welding. When a side positioning device 40 interferes, the corresponding lifting and avoiding device 50 can drive the side positioning device 40 to descend. After the medium frequency welding machine 60 passes, the lifting and avoiding device 50 drives the side positioning device 40 to rise to restore the side positioning. The medium frequency welding machine 60 stops to perform spot welding at regular intervals until it moves to the tail end of the anode plate and stops. After the double anode plate welding is completed, the medium frequency welding machine 60 can return to the starting position to wait for the welding of the next double anode plate.

[0023] This application is applicable to the processing of long double anode plates. The automatic welding process is as follows: First, the inverted anode plate is transported to the plate support frame 20. Then, the next forward anode plate is transported and stacked on the upper surface of the inverted anode plate, with the forward anode plate and the inverted anode plate facing each other vertically. Next, the two anode plates are welded at intervals along the length of the anode plate using this application to form an integral double anode plate. The welded double anode plate is then transported, packaged, and conveyed. This application can realize the automatic welding of anode plates, with stable welding quality, high production efficiency, and the ability to achieve mass automatic production. It is well-suited for the automated processing of long and thin plates, filling a gap in the industry.

[0024] The two end positioning devices 30 described earlier and later have basically the same structure, the main difference being their installation positions. They are symmetrically arranged to simultaneously abut the front and rear ends of the double anode plates for longitudinal positioning. (See also...) Figure 1 The end positioning device 30 includes end positioning cylinders located at the front and rear ends of the plate support frame 20. The end positioning cylinders are horizontally positioned, with their telescopic ends facing the front and rear ends of the anode plates, and end positioning plates are fixedly installed on these ends. The height of the end positioning plates corresponds to the height of the two stacked anode plates, and the width of the end positioning plates corresponds to the middle of the anode plates, allowing for clearance between the upper welding electrode 61 and the lower welding electrode 62. When both end positioning cylinders extend simultaneously, they move the two end positioning plates closer to and against the front and rear ends of the two anode plates, ensuring alignment of the front and rear ends. However, the width of the end positioning cylinders and end positioning plates is significantly smaller than the width of the anode plates, and this clearance affects the smooth passage of the upper welding electrode 61 and the lower welding electrode 62.

[0025] The longitudinal sliding device 70 can meet the sliding requirements of the medium-frequency welding machine 60 along the length of the anode plate. See also Figure 3 The longitudinal sliding device 70 includes a longitudinal slide rail 71 disposed on the welding base 10 along the length of the anode plate. A longitudinal slide block 72, slidably mounted along the longitudinal slide rail 71, is fixed to the bottom end of the base of the medium-frequency welding machine 60. A longitudinal geared rail 73 is fixed on the welding base 10. A sliding gear 74 and a sliding drive motor 75, which drives the sliding gear 74 to rotate, are mounted on the base of the medium-frequency welding machine 60. The sliding gear 74 meshes with the longitudinal geared rail 73 for transmission. When the sliding drive motor 75 runs, it drives the sliding gear 74 to rotate and move along the longitudinal geared rail 73, causing the medium-frequency welding machine 60 to slide along the longitudinal slide rail 71.

[0026] The two medium-frequency welding machines 60 described on the left and right are basically the same in structure, the main difference being their positions; they are arranged symmetrically on the left and right. (See also...) Figures 2 to 4The medium-frequency welding machine 60 includes a body, on which an upper cantilever 63 and a lower cantilever 64 are provided. An upper welding electrode 61 is mounted at the bottom end of the upper cantilever 63, and a lower welding electrode 62 is mounted at the top end of the lower cantilever 64. The upper welding electrode 61 and the lower welding electrode 62 are vertically opposed, and the distance between them is greater than the thickness between the welding areas at the ends of the stacked double anode plates. (See attached diagram for details.) Figure 4 The medium-frequency welding machine 60 mentioned above is existing technology, and its specific working principle will not be elaborated here.

[0027] The lifting and avoidance devices 50 and side positioning devices 40 on the left and right sides are symmetrically arranged and can operate synchronously or independently. The lifting and avoidance devices 50 ensure that the side positioning devices 40 can descend below the lower cantilever 64 of the medium-frequency welding machine 60, avoiding interference with the sliding of the medium-frequency welding machine 60. (See also...) Figure 5 and Figure 6 The lifting and avoidance device 50 includes a vertically arranged lifting and avoidance cylinder 51. The cylinder body of the lifting and avoidance cylinder 51 is fixed on the welding base frame 10. The side positioning device 40 is fixed to the cylinder rod end of the lifting and avoidance cylinder 51. The lifting and avoidance cylinder 51 can drive the side positioning device 40 to descend and avoid the moving medium frequency welding machine 60. The side positioning device 40 includes a side positioning cylinder 41 fixed on the lifting and avoidance cylinder 51. The side positioning cylinder 41 is arranged horizontally. The telescopic end of the side positioning cylinder 41 is arranged facing the side end of the two stacked anode plates, and a side positioning plate 42 is fixedly installed on the telescopic end. The height of the side positioning plate 42 is the same as the height of the two stacked anode plates. The lifting and avoiding cylinder 51 has a fixing plate 1 on its cylinder body, and a guide sleeve on the fixing plate 1. The side positioning cylinder 41 has a fixing plate 2 on its cylinder body, and a guide post 52 on the fixing plate 2. The guide post 52 is slidably disposed within the guide sleeve to ensure the stable installation of the side positioning cylinder 41. When both side positioning cylinders 41 extend simultaneously, the two side positioning plates 42 simultaneously abut against the side ends of the two anode plates, thereby laterally positioning the two anode plates.
