Description

Technical Field

[0001] The utility model belongs to the technical field of anode plate processing for hydrometallurgical zinc electrolysis, and particularly relates to a copper bar conveying device. Background Art

[0002] The production of the conductive cross beam of the anode plate includes pickling (removing oxidation) of the copper bar, tin hanging treatment of the copper bar (the purpose is to strengthen the combination of copper and lead), and lead water casting of the copper bar in the shaping cavity. At present, the transportation of copper bars during the processing process mostly adopts the method of manual handling. However, due to the heavy weight of the copper bars, the labor intensity of manual handling is large and the operation safety is poor. In addition, some conventional conveying devices cannot correct the placement position of the copper bars, which affects the grasping of the manipulator and is not conducive to automated production. Moreover, after pickling, some cleaning liquid remains on the surface of the copper bars. When hanging tin in the tin hanging furnace later, it often causes tin water to splash and scald the operator. Therefore, it is necessary to improve the copper bar conveying device in the prior art. Content of the Utility Model

[0003] The utility model aims at the above problems and provides a copper bar conveying device that can correct the placement position of the copper bars, has low labor intensity, good safety, high conveying efficiency, can dry the surface of the pickled copper bars, and improves the working environment.

[0004] The technical solution adopted by the utility model is: the copper bar conveying device includes a conveying rack, and is characterized in that: two groups of conveying chains arranged along the cross beam conveying direction are arranged on the conveying rack. The conveying chains are annularly arranged on the left and right sides of the upper part of the conveying rack. The front ends of the two groups of conveying chains are the feeding ends. The driven sprockets at the rear ends of the two groups of conveying chains are connected by a synchronous rotating shaft, and one of the driven sprockets is connected to the driving sprocket through a transmission chain. The rotating shaft of the driving sprocket is connected to the output end of a conveying motor arranged on the conveying rack; parallel return lifting cylinders arranged vertically are respectively arranged on the left and right sides of the front part of the conveying rack, and a copper bar centering mechanism for correcting the position of the cross beam copper bars is further arranged between the two groups of conveying chains in the middle of the conveying rack.

[0005] The copper bar centering mechanism includes a centering support connecting plate, on which two parallel centering sliding tracks are arranged. A centering sliding seat is arranged on the centering sliding tracks. The lower side of the centering sliding seat is slidably connected to the centering sliding tracks through sliding blocks. The upper side of the centering sliding seat is provided with a vertically arranged centering gripper lifting cylinder, and the upper end of the telescopic rod of the centering gripper lifting cylinder is provided with a lug gripper for correcting the position of the crossbeam copper bar through the crossbeam lug. Moreover, the centering sliding seat is also connected to the pulley at the output end of the centering motor through an annular centering transmission belt. The centering motor is used to drive the annular centering transmission belt to rotate reciprocally, thereby driving the centering sliding seat to move reciprocally on the centering sliding tracks. At the same time, the lifting and lowering of the lug gripper is driven by the telescopic movement of the centering gripper lifting cylinder and is in contact with the crossbeam lug, so as to perform centering adjustment on the position of the crossbeam copper bar that has been parallelly reset on the conveying chain.

[0006] Above the conveying machine frame and within the entire conveying range of the conveying chain, baking lamps are provided for heating the outer surface of the crossbeam copper bar at a high temperature. During the conveying process of the crossbeam copper bar, the baking lamps above the conveying machine frame are used to dry the residual cleaning acid solution on the crossbeam copper bar, effectively avoiding the splashing phenomenon during the subsequent tinning process of the crossbeam copper bar in the tinning furnace.

[0007] Copper bar stop blocks are respectively arranged on the left and right sides at the rear of the conveying machine frame. The copper bar stop blocks arranged at the rear in the conveying direction of the conveying chain are used to position and stop the crossbeam copper bar that has been parallelly reset and corrected in centering, facilitating the grasping by the subsequent operating manipulator.

[0008] In front of the parallel reset lifting cylinder and between the two groups of conveying chains, a photoelectric detection sensor for controlling the lifting cylinder is provided. The photoelectric detection sensor is fixedly connected to the conveying machine frame through a connecting frame. The photoelectric detection sensor located in front of the two parallel reset lifting cylinders is used to sense the crossbeam copper bar conveyed on the conveying chain. Then, according to the moving position of the crossbeam copper bar, the left and right parallel reset lifting cylinders are raised to make the crossbeam copper bar parallelly reset. After the parallel reset is completed, the parallel reset lifting cylinders are retracted and the crossbeam copper bar is continuously conveyed.

[0009] In front of the copper bar centering mechanism and between the two groups of conveying chains, a grating detection sensor for detecting the position of the crossbeam lug is provided. The grating detection sensor is fixedly connected to the conveying machine frame through a connecting frame. The grating detection sensor located in front of the copper bar centering mechanism is used to sense the position of the crossbeam lug on the crossbeam copper bar that has been parallelly reset. Then, according to the deviation of the position of the crossbeam lug, the lug gripper of the copper bar centering mechanism is used to perform centering positioning on the crossbeam copper bar.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] According to Figures 1 to 3 the specific structure of the present utility model will be described in detail. The copper bar conveying device includes a conveying frame 1, and two sets of conveying chains 6 arranged along the conveying direction of the cross beam are arranged on the conveying frame 1. The conveying chains 6 are annularly arranged on the left and right sides of the upper part of the conveying frame 1; the front ends of the two sets of conveying chains 6 are the feeding ends of the cross beam copper bars 13 conveyed thereon. The driven sprockets 5 at the rear ends of the two sets of conveying chains 6 are connected by a synchronous rotating shaft 7, and one of the driven sprockets 5 is connected to the driving sprocket 2 by a transmission chain 4, and the rotating shaft of the driving sprocket 2 is connected to the output end of the conveying motor 3 arranged on the conveying frame 1.

[0016] Above the conveying frame 1 and within the entire conveying range of the conveying chain 6, baking lamps are provided for heating the outer surface of the crossbeam copper strip 13 to a high temperature. Furthermore, during the conveying of the crossbeam copper strip 13, the baking lamps above the conveying frame 1 are used to dry the cleaning acid solution remaining on the crossbeam copper strip 13, effectively avoiding the splashing phenomenon during the tinning process of the crossbeam copper strip 13 in the tinning furnace. Also, copper strip stop blocks 8 are respectively arranged on the left and right sides at the rear of the conveying frame 1; the copper strip stop blocks 8 arranged at the rear of the conveying direction of the conveying chain 6 are used to position and stop the crossbeam copper strip 13 that has been parallelly aligned and corrected, facilitating the grasping by the subsequent operating manipulator.

[0017] On the left and right sides at the front of the conveying frame 1, vertically arranged parallel alignment lifting cylinders 10 are respectively provided. In front of the parallel alignment lifting cylinders 10 and between the two groups of conveying chains 6, a photoelectric detection sensor 9 for controlling the lifting cylinders is provided, and the photoelectric detection sensor 9 is fixedly connected to the conveying frame 1 through a connecting frame. Thus, the photoelectric detection sensor 9 located in front of the two parallel alignment lifting cylinders 10 senses the crossbeam copper strip 13 conveyed on the conveying chain 6, and according to the moving position of the crossbeam copper strip 13, the parallel alignment lifting cylinders 10 on the left and right sides are raised to make the crossbeam copper strip 13 parallelly align. After the parallel alignment is completed, the parallel alignment lifting cylinders 10 are retracted and the crossbeam copper strip 13 is continuously conveyed.

[0018] Moreover, between the two groups of conveying chains 6 in the middle of the conveying frame 1, a copper strip centering mechanism 12 for correcting the position of the crossbeam copper strip 13 by using the crossbeam lug 14 is also provided. In front of the copper strip centering mechanism 12 and between the two groups of conveying chains 6, a grating detection sensor 11 for detecting the position of the crossbeam lug 14 is provided; and the grating detection sensor 11 is fixedly connected to the conveying frame 1 through a connecting frame. Furthermore, the grating detection sensor 11 located in front of the copper strip centering mechanism 12 senses the position of the crossbeam lug 14 on the crossbeam copper strip 13 that has been parallelly aligned; it can be understood that according to specific usage requirements, only one of the lugs can be used for centering. Thus, according to the deviation of the position of the crossbeam lug 14, the crossbeam copper strip 13 is centered and positioned by the lug gripper 21 of the copper strip centering mechanism 12.

[0019] The copper bar centering mechanism 12 includes a centering support connecting plate 15, on which two parallel centering sliding tracks 16 are arranged, and a centering sliding seat 17 is arranged on the centering sliding tracks 16; the lower side of the centering sliding seat 17 is slidably connected to the centering sliding tracks 16 through sliding blocks, and a vertically arranged centering gripper lifting cylinder 20 is arranged on the upper side of the centering sliding seat 17. At the upper end of the telescopic rod of the centering gripper lifting cylinder 20, an ear gripper 21 is arranged for correcting the position of the crossbeam copper bar 13 through the crossbeam ear 14. Moreover, the centering sliding seat 17 is also connected to the pulley at the output end of the centering motor 19 through an annular centering transmission belt 18. Then, the centering motor 19 is used to drive the annular centering transmission belt 18 to rotate reciprocally, so as to drive the centering sliding seat 17 to move reciprocally on the centering sliding tracks 16; at the same time, the telescopic movement of the centering gripper lifting cylinder 20 is used to drive the ear gripper 21 to lift and contact the crossbeam ear 14, so as to perform centering adjustment on the position of the crossbeam copper bar 13 that has been parallelly reset on the conveying chain 6.

[0020] When the copper bar conveying device is in use, first, the crossbeam copper bar 13 after pickling and cleaning is placed at the feeding end in the front of the two groups of conveying chains 6, and then, the conveying motor 3 drives the driving sprocket 2 to rotate, and drives the two groups of conveying chains 6 to rotate synchronously through the transmission chain 4, the driven sprocket 5 and the synchronous rotating shaft 7, so as to move the crossbeam copper bar 13 towards the rear of the conveying device. When the photoelectric detection sensor 9 senses the crossbeam copper bar 13 conveyed on the conveying chain 6, the left and right parallel reset lifting cylinders 10 are raised, and the crossbeam copper bar 13 is parallelly reset by the blocking and stopping action of the two sides' parallel reset lifting cylinders 10. After the parallel reset is completed, the two sides' parallel reset lifting cylinders 10 are retracted, and the crossbeam copper bar 13 is continuously conveyed towards the rear.

[0021] After that, the grating detection sensor 11 is used to sense the position of the crossbeam ear 14 on the crossbeam copper bar 13 that has been parallelly reset, so as to perform centering positioning on the crossbeam copper bar 13 by using the ear gripper 21 of the copper bar centering mechanism 12 according to the deviation of the position of the crossbeam ear 14. Moreover, a copper bar blocking block 8 arranged at the rear in the conveying direction of the conveying chain 6 is used to position and block the crossbeam copper bar 13 that has been parallelly reset and corrected in centering, so as to facilitate the grasping of the subsequent operating manipulator. At the same time, during the whole process of the crossbeam copper bar 13 being conveyed on the conveying device, the baking lamp above the conveying rack 1 is used to dry the residual cleaning acid solution on the crossbeam copper bar 13, so as to avoid the splashing phenomenon during the subsequent tinning process of the crossbeam copper bar 13 in the tinning furnace.
