Description

Technical Field

[0001] The utility model belongs to the technical field of lead-based anode plate processing for wet electrolysis, and particularly relates to a bottom plate bidirectional conveying mechanism for an anode plate. Background Art

[0002] Lead-based anode plates used in wet electrolysis are welded together from a conductive beam and a base plate. The conductive beam is composed of lead and copper, while the base plate is made of a lead-silver alloy. The existing method for welding the anode plate base plate and the conductive beam relies on a manually operated suction cup mechanism to pick up the anode plate base plate (which weighs 215 to 245 kg) and place it on the welding platform. Furthermore, due to the porous structure of the base plate, the suction cup mechanism requires special fabrication. Furthermore, after welding, the anode plate must be transported to the next process step using the suction cup mechanism again. However, due to the heavy weight and easy deformation of the anode plate base plate, lifting and transporting are difficult, resulting in low efficiency, unstable product quality, and high labor costs. Therefore, it is necessary to improve the existing anode plate conveying methods and devices. Utility Model Content

[0003] The utility model aims to solve the above problems and provides a two-way conveying mechanism for the bottom plate of the anode plate, which can ensure the flatness of the bottom plate, directly send the bottom plate into and out of the welding station by the conveying mechanism, reduce the damage to the bottom plate during the loading and unloading process, have low labor intensity, high working efficiency, and effectively save labor costs.

[0004] The technical solution adopted by the present utility model is: the bottom plate bidirectional conveying mechanism of the anode plate includes a bidirectional conveying base, which is characterized in that: a transverse conveying frame is provided on the bidirectional conveying base, and a plurality of groups of transverse conveying rollers are rotatably provided on the transverse conveying frame, and the driving ends of the transverse conveying rollers are respectively connected to the output ends of the transverse conveying drive motor through a conveying roller transmission mechanism; a longitudinal conveying frame that can be raised and lowered is provided above the transverse conveying frame, and a plurality of groups of longitudinal conveying chains are provided on the longitudinal conveying frame, and the driving ends of the longitudinal conveying chains are respectively connected to the output ends of the longitudinal conveying drive motor through a transmission chain transmission mechanism; and, each group of longitudinal conveying chains on the longitudinal conveying frame and each group of transverse conveying rollers on the transverse conveying frame are arranged in an interlaced manner.

[0005] The two sides of the longitudinal conveying frame are slidably connected to the longitudinal frame lifting guide rails arranged on the longitudinal frame lifting base through sliding blocks, and a vertically arranged longitudinal frame lifting cylinder is provided between the longitudinal conveying frame and the horizontal plate at the bottom of the longitudinal frame lifting base; the bottom of the longitudinal frame lifting base is also slidably arranged on the lifting base longitudinal displacement guide rail arranged on the upper side of the bidirectional conveying base, and a horizontally longitudinally arranged lifting base longitudinal displacement cylinder is provided between the horizontal plate at the bottom of the longitudinal frame lifting base and the bidirectional conveying base; a plurality of groups of bottom plate conveying chain frames arranged in parallel are provided on the upper side of the longitudinal conveying frame, and longitudinal conveying chains are respectively provided on the bottom plate conveying chain frames, and transverse rollers for arranging transverse conveying rollers are respectively provided with staggered intervals between two adjacent groups of bottom plate conveying chain frames. The longitudinal conveying frame and the longitudinal conveying chain thereon are driven to rise or fall along the longitudinal frame lifting guide rail by the extension and contraction of the longitudinal frame lifting cylinder, and then the anode plate bottom plate is longitudinally conveyed to the welding station by the longitudinal conveying chain whose position is higher than the transverse conveying roller on the transverse conveying frame (the longitudinal conveying frame rises), and the anode plate after assembly welding is dropped onto the transverse conveying roller of the transverse conveying frame by the longitudinal conveying chain whose position is lower than the transverse conveying roller on the transverse conveying frame (the longitudinal conveying chain and the transverse conveying roller are arranged alternately with each other), and then the anode plate after assembly welding is laterally conveyed to the next process; at the same time, the longitudinal position of the longitudinal frame lifting base and the longitudinal conveying frame thereon is adjusted by the extension and contraction of the longitudinal shift cylinder of the lifting base, so as to facilitate the alignment and conveying of the anode plate bottom plate to the welding position correction and flattening device of the welding station.

[0006] Crossbeam conveyor chain racks are also provided on the outside of the bottom plate conveyor chain racks on both sides of the longitudinal conveyor frame. These crossbeam conveyor chain racks are arranged parallel to the bottom plate conveyor chain racks and are also provided with longitudinal conveyor chains. The front ends of these crossbeam conveyor chain racks protrude from the front ends of the bottom plate conveyor chain racks. The protruding crossbeam conveyor chain racks on both sides of the longitudinal conveyor frame and the longitudinal conveyor chains thereon are used to provide auxiliary support and conveyance for the conductive crossbeams of the welded anode plates, thereby improving the stability of the longitudinal conveyance of the welded anode plates.

[0007] The longitudinal conveying drive motor is fixedly mounted on the longitudinal conveying frame, and the conveying chain transmission mechanism includes a longitudinal conveying drive chain connected to the output end of the longitudinal conveying drive motor. The longitudinal conveying drive chain is connected to a drive sprocket at the end of a transversely arranged longitudinal chain transmission shaft. In addition, the drive ends of the longitudinal conveying chains provided on the base plate conveying chain frame and the crossbeam conveying chain frame are also connected to the longitudinal chain transmission shaft via sprockets. The longitudinal conveying drive motor and the longitudinal conveying drive chain drive the longitudinal chain transmission shaft to rotate, thereby driving the longitudinal conveying chains on each group of base plate conveying chain frames and the crossbeam conveying chain frames on both sides to rotate synchronously, thereby conveying the anode plate base plate forward to the welding station. After welding, the welded anode plate is conveyed backward to the base plate bidirectional conveying mechanism.

[0008] A base plate positioning and clamping mechanism is also provided within the staggered arrangement of transverse rollers between the two adjacent sets of base plate conveyor chain frames. The base plate positioning and clamping mechanism comprises a base plate positioning and clamping cylinder fixedly mounted on the longitudinal conveyor frame, and a positioning and clamping swing arm is provided at the driving end of the base plate positioning and clamping cylinder. After the anode plate base plate is conveyed forward to the welding station, the base plate positioning and clamping mechanism utilizes the base plate positioning and clamping cylinder to drive the positioning and clamping swing arm to swing upward, thereby fixing the welding position of the anode plate base plate, thereby facilitating accurate assembly welding of the anode plate base plate and the anode plate conductive beam by the friction stir welding machine.

[0009] The transverse conveyor frame is slidably connected to four transverse conveyor guide rails on four transverse conveyor lifting bases via sliding blocks. The transverse conveyor lifting bases are fixedly mounted on a bidirectional conveyor base at the bottom, and a transverse conveyor lifting cylinder is disposed vertically between the transverse conveyor frame and the bidirectional conveyor base. A plurality of sets of parallel transverse conveyor rollers are disposed on the upper side of the transverse conveyor frame, and longitudinal chains for arranging longitudinal conveyor chains are disposed in staggered intervals between adjacent sets of transverse conveyor rollers. The transverse conveyor frame and the transverse conveyor rollers thereon are driven to rise or fall along the transverse conveyor lifting rails by the extension and contraction of the transverse conveyor lifting cylinders. The transverse conveyor rollers positioned higher than the longitudinal conveyor chains on the longitudinal conveyor frame (when the transverse conveyor frame is raised) are used to transversely convey the welded anode plates to the next process. Furthermore, when the longitudinal conveyor chains on the longitudinal conveyor frame longitudinally convey the anode plate bottom plates to the welding station, the transverse conveyor frame is lowered, thereby ensuring that the staggered transverse conveyor rollers and the longitudinal conveyor chains do not interfere with each other during operation.

[0010] The transverse conveying drive motor is fixedly mounted on the transverse conveying frame, and the conveying roller transmission mechanism includes a transverse conveying drive chain assembly connected to the output end of the transverse conveying drive motor. The transmission chains in the transverse conveying drive chain assembly are respectively connected to the drive sprockets at the ends of the transverse conveying rollers at corresponding positions. The transmission chains in the transverse conveying drive chain assembly are respectively connected to each other via synchronous sprockets. The transverse conveying drive motor and the transverse conveying drive chain assembly are used to synchronously drive the multiple sets of transverse conveying rollers on the transverse conveying frame, thereby transversely conveying the welded anode plates to the next process.

[0011] Several sets of auxiliary crossbeam lifting rollers are rotatably mounted on the side of the transverse conveyor frame facing the welding station. These rollers are arranged parallel to the transverse conveyor rollers. During the process of horizontally conveying the welded anode plates, the auxiliary crossbeam lifting rollers, located on the outside of the transverse conveyor frame, rotate to assist in supporting the conductive crossbeams on the welded anode plates, thereby ensuring smooth transverse transport of the welded anode plates.

[0012] The beneficial effects of the utility model are as follows: since the utility model adopts a bidirectional conveying base provided with a transverse conveying frame, the transverse conveying frame is rotatably provided with several groups of transverse conveying rollers, and the driving ends of the transverse conveying rollers are respectively connected to the output ends of the transverse conveying drive motors through the conveying roller transmission mechanism; a longitudinal conveying frame that can be raised and lowered is provided above the transverse conveying frame, and the longitudinal conveying frame is provided with several groups of longitudinal conveying chains, and the driving ends of the longitudinal conveying chains are respectively connected to the output ends of the longitudinal conveying drive motors through the transmission chain transmission mechanism, and the groups of longitudinal conveying chains on the longitudinal conveying frame and the groups of transverse conveying rollers on the transverse conveying frame are arranged in an alternating manner, so its design is reasonable and the structure is compact, which can ensure the flatness of the bottom plate. After the bottom plate is rolled and punched, it does not need to be removed from the machine, and the conveying mechanism directly sends the bottom plate into and out of the welding station, reducing the damage to the bottom plate during the loading and unloading process, with low labor intensity and high working efficiency, effectively saving labor costs.

DETAILED DESCRIPTION

[0020] according to Figures 1 to 6 The specific structure of the present invention is described in detail. The bottom plate bidirectional conveying mechanism of the anode plate includes a bidirectional conveying base 1, on which a transverse conveying frame 5 is provided. A plurality of groups of parallel transverse conveying rollers 6 are provided on the upper side of the transverse conveying frame 5. Between two adjacent groups of transverse conveying rollers 6, longitudinal chain staggered spacing 23 for arranging longitudinal conveying chains 3 is provided. The driving ends of the transverse conveying rollers 6 are connected to the output end of a transverse conveying drive motor 7 fixed to the transverse conveying frame 5 through a conveying roller transmission mechanism.

[0021] The conveyor roller drive mechanism includes a transverse conveyor drive chain assembly 22 connected to the output end of the transverse conveyor drive motor 7. The drive chains in the transverse conveyor drive chain assembly 22 are respectively connected to the drive sprockets at the ends of the transverse conveyor rollers 6 at corresponding positions. The drive chains in the transverse conveyor drive chain assembly 22 are respectively connected to the drive sprockets at the ends of the transverse conveyor rollers 6 at corresponding positions. The drive chains in the transverse conveyor drive chain assembly 22 are respectively connected to each other via synchronous sprockets. The transverse conveyor drive motor 7 and the transverse conveyor drive chain assembly 22 are used to synchronously drive multiple sets of transverse conveyor rollers 6 on the transverse conveyor frame 5, thereby transversely conveying the welded anode plates to the next process. In addition, on the side of the transverse conveyor frame 5 facing the welding station, there are also several sets of crossbeam auxiliary lifting rollers 24 rotatably arranged. The crossbeam auxiliary lifting rollers 24 are arranged parallel to the transverse conveyor rollers 6. Therefore, when the transverse conveyor rollers 6 transversely convey the welded anode plates, the crossbeam auxiliary lifting rollers 24 arranged on the outside of the transverse conveyor frame 5 rotate to assist in supporting the conductive crossbeams on the welded anode plates, thereby ensuring smooth transverse conveyance of the welded anode plates.

[0022] At the same time, in order to improve the flexibility of the use of the device, the four sides of the transverse conveying frame 5 can be slidably connected to the transverse frame lifting guide rails 20 set on the four groups of transverse frame lifting bases 19 through sliding blocks. The transverse frame lifting base 19 is fixedly set on the two-way conveying base 1 at the bottom, and a vertically arranged transverse frame lifting cylinder 21 is set between the transverse conveying frame 5 and the two-way conveying base 1; then, the transverse frame lifting cylinder 21 is extended and retracted to drive the transverse conveying frame 5 and the transverse conveying roller 6 thereon to rise or fall along the transverse frame lifting guide rail 20, so as to utilize the transverse conveying roller 6 (the transverse conveying frame 5 rises) whose position is higher than the longitudinal conveying chain 3 on the longitudinal conveying frame 2 to smoothly convey the welded anode plate to the next process laterally; and, when the longitudinal conveying chain 3 on the longitudinal conveying frame 2 conveys the anode plate bottom plate longitudinally to the welding station, the transverse conveying frame 5 is lowered, so that the transverse conveying rollers 6 and the longitudinal conveying chain 3, which are arranged at intervals and staggered, do not interfere with each other during work. It is understandable that, according to specific usage requirements, the transverse transport frame 5 can also be designed as a fixed structure that cannot be raised or lowered.

[0023] A longitudinal conveyor frame 2, capable of being raised and lowered, is installed above the transverse conveyor frame 5. The two sides of the longitudinal conveyor frame 2 are slidably connected to longitudinal frame lift guide rails 9 provided on the longitudinal frame lift base 8 via sliding blocks. A vertically arranged longitudinal frame lift cylinder 10 is installed between the longitudinal conveyor frame 2 and the horizontal plate at the bottom of the longitudinal frame lift base 8. Furthermore, the bottom of the longitudinal frame lift base 8 is also slidably installed on a lift base longitudinal shift guide rail 11 arranged on the upper side of the bidirectional conveyor base 1. A horizontally arranged lift base longitudinal shift cylinder 12 is installed between the horizontal plate at the bottom of the longitudinal frame lift base 8 and the bidirectional conveyor base 1. Several groups of bottom plate conveying chain frames 15 arranged in parallel are provided on the upper side of the longitudinal conveying frame 2, and longitudinal conveying chains 3 are respectively provided on the bottom plate conveying chain frames 15; between two adjacent groups of bottom plate conveying chain frames 15, there are also transverse roller staggered arrangement intervals 16 for arranging transverse conveying rollers 6, that is: each group of longitudinal conveying chains 3 on the longitudinal conveying frame 2 and each group of transverse conveying rollers 6 on the transverse conveying frame 5 are arranged in an intermittent staggered manner.

[0024] Furthermore, the longitudinal frame lifting cylinder 10 is extended and retracted to drive the longitudinal conveying frame 2 and the longitudinal conveying chain 3 thereon to rise or fall along the longitudinal frame lifting guide rail 9, so that the longitudinal conveying chain 3, which is positioned higher than the transverse conveying roller 6 on the transverse conveying frame 5 (the longitudinal conveying frame 2 is raised), is used to longitudinally convey the anode plate base plate to the welding station; and the longitudinal conveying chain 3, which is positioned lower than the transverse conveying roller 6 on the transverse conveying frame 5 (the longitudinal conveying frame 2 is lowered), is used to drop the welded anode plate onto the transverse conveying roller 6 of the transverse conveying frame 5 (the longitudinal conveying chain 3 and the transverse conveying roller 6 are arranged alternately with each other), thereby laterally conveying the welded anode plate to the next process. In addition, the longitudinal shift cylinder 12 of the lifting base can be extended and retracted to adjust the longitudinal position of the longitudinal frame lifting base 8 and the longitudinal conveying frame 2 thereon, so as to facilitate the alignment and conveying of the anode plate base plate to the welding position correction and flattening device of the welding station.

[0025] Crossbeam conveying chain frames 17 are respectively provided on the outer sides of the bottom plate conveying chain frames 15 on the left and right sides of the longitudinal conveying frame 2. The crossbeam conveying chain frames 17 are arranged parallel to the bottom plate conveying chain frames 15. The crossbeam conveying chain frames 17 are also respectively provided with longitudinal conveying chains 3, and the front end of the crossbeam conveying chain frames 17 protrudes from the front end of the bottom plate conveying chain frame 15; the protruding crossbeam conveying chain frames 17 on both sides of the longitudinal conveying frame 2 and the longitudinal conveying chains 3 thereon are used to assist in supporting and conveying the conductive beams of the anode plates after assembly welding, thereby improving the longitudinal conveying stability of the anode plates after assembly welding.

[0026] The longitudinal conveyor drive motor 4 is fixedly mounted on the vertically movable longitudinal conveyor frame 2. The output end of the longitudinal conveyor drive motor 4 is connected to the drive end of each set of longitudinal conveyor chains 3 via a conveyor chain transmission mechanism. The conveyor chain transmission mechanism includes a longitudinal conveyor drive chain 13 connected to the output end of the longitudinal conveyor drive motor 4. The longitudinal conveyor drive chain 13 is connected to a drive sprocket at the end of a transversely arranged longitudinal chain transmission shaft 14. Furthermore, the drive ends of the longitudinal conveyor chains 3 installed on each base plate conveyor chain frame 15 and the two side crossbeam conveyor chain frames 17 are respectively connected to the longitudinal chain transmission shaft 14 via sprockets. The longitudinal conveyor drive motor 4 and the longitudinal conveyor drive chain 13 drive the longitudinal chain transmission shaft 14 to rotate, thereby driving the longitudinal conveyor chains 3 on each set of base plate conveyor chain frames 15 and the two side crossbeam conveyor chain frames 17 to rotate synchronously. This transports the anode plate base plate forward to the welding station. After welding, the welded anode plate is then transported back to the base plate bidirectional conveyor mechanism.

[0027] In addition, a bottom plate positioning and clamping mechanism 18 for fixing the welding position of the anode plate bottom plate is provided in the staggered interval 16 of the transverse rollers between the two adjacent groups of bottom plate conveying chain frames 15. The bottom plate positioning and clamping mechanism 18 includes a bottom plate positioning and clamping cylinder fixedly arranged on the longitudinal conveying frame 2, and a positioning and clamping swing arm is provided at the driving end of the bottom plate positioning and clamping cylinder. After the anode plate bottom plate is conveyed forward to the welding station, the bottom plate positioning and clamping cylinder of the bottom plate positioning and clamping mechanism 18 is used to drive the positioning and clamping swing arm to swing upward to fix the welding position of the anode plate bottom plate, so as to facilitate the stir friction welding machine to accurately weld the anode plate bottom plate and the anode plate conductive beam.

[0028] When the bottom plate bidirectional conveying mechanism of the anode plate is used, first, the bottom plate conveying roller conveys the anode plate bottom plate processed in the previous process to the longitudinal conveying frame 2 of the bottom plate bidirectional conveying mechanism, and then the longitudinal frame lifting cylinder 10 is extended to drive the longitudinal conveying frame 2 and the longitudinal conveying chain 3 thereon to rise to the height of the longitudinal transfer. After that, the longitudinal conveying drive motor 4 is used to drive each group of bottom plate conveying chain frames 15 and the longitudinal conveying chains 3 on the crossbeam conveying chain frames 17 on both sides to rotate synchronously. At the same time, the lifting base longitudinal shift cylinder 12 is extended to adjust the longitudinal position of the longitudinal frame lifting base 8 and the longitudinal conveying frame 2 thereon, so as to utilize each group of longitudinal conveying chains 3 whose position is higher than the transverse conveying roller 6 on the transverse conveying frame 5 to convey the anode plate bottom plate forward and in position to the welding station. After the anode plate base plate is conveyed to the welding station, the welding part correction and flattening device corrects and flattens the welding parts of the anode plate base plate and the anode plate conductive beam, and uses the base plate positioning and clamping mechanism 18 to fix the welding position of the anode plate base plate. Subsequently, the stir friction welding machine welds the anode plate base plate and the anode plate conductive beam together.

[0029] After the anode plate bottom plate and the anode plate conductive beam are welded, the lifting base longitudinal shift cylinder 12 is retracted to retract the longitudinal frame lifting base 8, the longitudinal conveying frame 2 thereon, and the welded anode plates onto the bottom plate bidirectional conveying mechanism; then, the longitudinal frame lifting cylinder 10 is retracted to drive the longitudinal conveying frame 2 and the longitudinal conveying chain 3 thereon to descend to the bottom of the transverse conveying frame 5 through the longitudinal chain staggered arrangement interval 23 (the transverse conveying frame 5 can also be appropriately raised upward by the transverse frame lifting cylinder 21), thereby causing the welded anode plates to fall onto the various sets of transverse conveying rollers 6 of the transverse conveying frame 5, which are located higher than the longitudinal conveying frame 2. Afterwards, the transverse conveying drive motor 7 is used to synchronously drive the multiple sets of transverse conveying rollers 6 on the transverse conveying frame 5, thereby transversely conveying the welded anode plates to the next process.
