As shown in fig. 1 to 8, the in-tank coating film detector 100 of the present invention includes a mounting frame, a water injection column 5 for injecting electrolyte into the tank 30, a detection column 6 for detecting the tank 30, a water suction pipe 7 for extracting the electrolyte from the tank 30, a detection lifting device 8 for moving the mounting frame in a vertical direction, and an electrolyte tank for storing the electrolyte, wherein the water injection column 5, the detection column 6, and the water suction pipe 7 are all fixedly mounted on the mounting frame, and the water injection column 5 and the water suction pipe 7 are respectively communicated with the electrolyte tank. This scheme is through corresponding setting up water injection post 5, detection post 6 and the pipe 7 that absorbs water according to the detection step substep, loads electrolyte and two links of electrolyte are absorb in later stage through increasing earlier stage for this device is automatic, intelligent degree is higher, has also reduced artificial cost. Meanwhile, during detection, the devices in all steps can independently operate, and the efficiency of in-tank coating detection is improved.
The structure of the detecting instrument is completely different compared with the prior detecting instrument, wherein the detecting step is divided into three testing columns, namely a water injection column 5 for applying electrolyte in the first step, a detecting column 6 for applying electricity to detect in the second part and a water suction pipe 7 for finally absorbing the electrolyte. This scheme increases and loads two links of electrolyte in earlier stage and later stage absorption electrolyte (carry the electrolyte and artifical electrolyte of dumping for people's frock before usually) for this device is automatic more, intelligent, has reduced artificial cost. Meanwhile, the two structures and the electrolyte tank form circulation, so that the electrolyte can be recycled for many times, the electrolyte consumption is reduced, and the cost is saved.
More important, this device sets up according to the detection step substep for each step can move simultaneously, is that three posts can correspond three jar of body 30 simultaneously and carry out the work that corresponds promptly, and a jar body 30 only need loop through after the function of three posts, alright obtain accomplishing whole detection flow, has improved detection efficiency. Correspondingly, in this scheme, water injection post 5, detection post 6 and the supporting setting of the 7 three of pipe that absorbs water only need set up a plurality of posts of the same type (the post quantity that every step that corresponds set up should be the same) alright operate a plurality of jar bodies 30 at same step, promotion detection efficiency that can be bigger.
In this embodiment, the water injection column 5 includes a first tank top seat 51, a water injection pipe 52 communicated with the electrolyte tank, a plurality of water level probes 53 for detecting the height of the electrolyte in the tank, and a water level common ground probe 54, wherein the water injection pipe 52 penetrates through the first tank top seat 51, the plurality of water level probes 53 and the water level common ground probe 54 are all fixed on the lower end surface of the first tank top seat 51, the plurality of water level probes 53 have different lengths, and when the water injection column is electrically conductive, the plurality of water level probes 53, the electrolyte and the water level common ground probe 54 form an electric circuit. The height of the electrolyte in the tank is an important factor influencing the detection result, and the electrolyte meeting the height required by detection needs to be injected into the tank, so that the accuracy of the detection result can be ensured. In this embodiment, a plurality of water level probes 53 with different lengths are disposed corresponding to the tanks 30 with different specifications, so as to correspondingly detect the liquid level heights of the electrolytes in the tanks 30 with different specifications. The liquid level height of the tank 30, which is required to meet the detection requirement, is higher corresponding to the tank 30 with the lower height of the tank 30, and at the moment, the electric control box judges the liquid level height only through the water level probe 53 with the shorter length; and to the higher jar body 30 of jar body 30 height, the liquid level height that its jar body 30 needs to satisfy the detection is also lower, and the electric cabinet only judges liquid level height through the longer water level probe 53 of length this moment, and the liquid level probe detection that corresponds different lengths through different jar bodies 30 ensures that the jar interior liquid level of the jar body 30 that awaits measuring can reach appointed demand.
When carrying out the water injection flow, it has had the jar body 30 of waiting to detect to first-selected 5 below of water injection post to confirm through photoelectric switch, later make when detecting elevating gear 8 and driving the mounting bracket downstream, water injection post 5 also moves down thereupon, just stop until the lower terminal surface of first jar footstock 51 contacts the top edge of jar body 30, a plurality of water level probes 53 this moment, water level is altogether probe 54 and water injection pipe 52 all is located the jar body 30 inside that awaits measuring, later the water injection pump between water injection pipe 52 and the electrolyte tank starts, pour into jar body 30 with the electrolyte extraction, detect the liquid level height through the liquid level probe that corresponds jar body 30 specification this moment, when this liquid level probe contacts electrolyte, transmission information gives the electric cabinet, make the water injection pump stall, the water injection is accomplished this moment. Detect elevating gear 8 and drive the mounting bracket rebound, water injection post 5 also rebound until leaving jar body 30, this moment jar body 30 through the conveyer belt conveying circulation can enter into the detection post 6 of below and carry out the circular telegram and detect.
In this embodiment the detection post 6 includes second tank footstock 61, passes second tank footstock 61 and only can be along the regulation liquid level post 62 that second tank footstock 61 vertical direction removed, be used for the drive adjust liquid level post 62 vertical direction upward movement adjust elevation structure 63, be used for contacting the outside last side head subassembly of the jar body 30 that awaits measuring and be used for with jar interior electrolyte direct contact's measuring electrode probe 65, adjust elevation structure 63 set up in adjust liquid level post 62 top and be connected with it screw thread rotation, last side head subassembly with measuring electrode probe 65 all set up in the lower terminal surface of second tank footstock 61, during electrically conductive, last side head subassembly, the jar body 30 that awaits measuring, electrolyte and measuring electrode probe 65 form the electric circuit. The detection post 6 in this embodiment can accomplish the detection to the integrality of coating film in the internal portion of jar body 30, its structural contrast also has great difference to traditional detector in the past, wherein the biggest difference lies in that traditional scheme needs to place jar body 30 on the blade holder mechanism to jar body 30 external contact, and this scheme is through setting up the edge that the upside head subassembly of second jar footstock 61 contacted jar body 30 top to realize the external contact to jar body 30, this kind of mode makes upside head subassembly and measurement electrode probe 65 together remove, can contact or keep away from jar body 30 in the lump along with detecting elevating gear 8 lift, jar body 30 need not to place on the blade holder mechanism, need not the location, can be directly through conveyor transport jar body 30, need not to carry the transportation through the manipulator centre gripping, the cost is reduced and very big improvement work efficiency.
The upper side head assembly in the scheme has various embodiments: the following are two realizable embodiments
The first embodiment is as follows: the upper head assembly includes a support 641 fixed to the second tank top mount 61, a torsion spring, and a contact block 642 rotatably fixed to the support 641 by the torsion spring. Because the second tank top seat 61 is lifted and moved along with the lifting device 8, in the process of detection, if the contact block 642 is directly and rigidly contacted with the tank 30 to be detected, the tank 30 may be directly cracked, for this reason, in this embodiment, the contact block 642 is sleeved on the torsion spring through the design of the torsion spring, when the contact block 642 is contacted with the top edge of the tank 30 to be detected, the contact block 642 can rotate upward so as not to directly crush the tank 30, and meanwhile, the elasticity of the torsion spring can drive the contact block 642 to rotate reversely, so that the contact block 642 is in close contact with the top edge of the tank 30 to be detected. The accuracy of detection is ensured. Meanwhile, the contact block 642 is made of a conductive material, when detection is carried out, the contact block 642, the electrolyte and the measuring electrode probe 65 form an electric loop, and the electric cabinet can judge whether the coating in the tank is complete or not by detecting the resistance value condition at the moment.
Example two: the upper side head assembly comprises a 7-shaped frame 643 fixed on the top end surface of the second tank top seat 61, a knife edge rod 644 penetrating through and capable of sliding along the second tank top seat 61 and the 7-shaped frame 643, and an adjusting spring 645, wherein the shaft of the knife edge rod 644 is provided with a bulge, the spring is sleeved on the knife edge rod 644, one end of the spring is fixed on the 7-shaped frame 643, and the other end of the spring is clamped in the bulge. In order to prevent the tank 30 to be tested from being crushed by the knife-edge rod 644 in this embodiment, the adjusting spring 645 is correspondingly designed, wherein when the upper head assembly is lowered along with the detection lifting device 8, the knife-edge rod 644 directly contacts the top edge of the tank 30 to be tested, at this time, if the upper head assembly is further lowered, the knife-edge rod 644 rises upwards along the second tank top seat 61 to prevent the tank 30 from being crushed directly, and at the same time, the knife-edge rod 644 rises upwards to make the bulge close to the 7-type frame 643, and the adjusting spring 645 between the two is stressed to contract. The self-expanding acting force of the adjusting spring 645 also drives the knife edge rod 644 to be in close contact with the top edge of the tank body 30 to be detected, so that the detection accuracy is ensured. Meanwhile, the knife edge rod 644 is made of a conductive material, when detection is carried out, the knife edge rod 644, electrolyte and the measuring electrode probe 65 form an electric loop, and the electric cabinet can judge whether the in-tank coating is complete or not by detecting the resistance value condition at the moment.
Preferably, the contact block 642 and the knife-edge rod 644 can perform the function of detecting the integrity of the coating film in the can, but when only one contact block 642 or knife-edge rod 644 contacts the can 30 to be tested, the can 30 is easily inclined due to unstable contact, so that a plurality of contact blocks 642 or knife-edge rods 644 can be used in cooperation, and a plurality of contact blocks 642 or knife-edge rods 644 are annularly and alternately arranged at the bottom of the second can top base 61. Wherein this embodiment adopts two relative settings, just can push down the jar body 30 that awaits measuring at both ends, keeps the steady of the jar body 30 when examining, prevents that the slope of the interior electrolyte of jar body 30 from influencing the accuracy of testing result.
This detection post 6 traditional detecting instrument than in the past still has the liquid level control structure that is used for adjusting the interior liquid level height of jar body 30, because the jar body 30 that awaits measuring in this scheme loops through water injection post 5 through conveyor, detection post 6 and suction pipe 7, wherein in the flow of injecting into electrolyte, the risk that jar body 30 electrolyte spills can appear in transportation process if the liquid level of jar body 30 is too high, this kind of condition has not only caused detecting instrument's pollution, the inside electrolyte of jar body 30 spills and the contact has not the problem that detection data is incorrect then can appear in the jar incision edge of coating simultaneously. Therefore, the solution is correspondingly provided with the adjusting liquid level column 62 which can move only along the vertical direction of the second tank top seat 61 and the adjusting lifting structure 63 which is used for driving the adjusting liquid level column 62 to move in the vertical direction. The size of the adjusting liquid level column 62 is smaller than the opening of the tank 30, and the adjusting liquid level column can enter the tank 30, and the measuring electrode probe 65 is arranged on the side edge of the adjusting liquid level column 62. The adjusting liquid level column 62 is provided with a recessed sliding groove, and the corresponding second tank top seat 61 is provided with a protruding sliding block capable of sliding along the sliding groove. Through this setting can make the place ahead pour into the required electrolyte that pours into in the electrolyte flow into and reduce, can not appear the unrestrained problem of jar interior electrolyte in transportation process, the liquid level control structure can make the liquid level height of jar interior electrolyte satisfy the detection needs simultaneously, ensures the accuracy that detects.
Preferably, the adjusting lifting structure 63 in this embodiment is used to drive the adjusting liquid level column 62 to move up and down vertically, and there are various implementation manners, and the following is a practical manner: adjust elevation structure 63 and include lift lead screw 631 and be used for the drive lift lead screw 631 pivoted motor 632, adjust the rotatable setting in of liquid level post 62 in lift lead screw 631, motor 632 drives when lift lead screw 631 rotates, adjust liquid level post 62 and can follow second jar footstock 61 and go up and down to slide.
