Referring to fig. 1-6, an automatic on-line weighing system for a honeycomb coating applied to an automobile exhaust system comprises a workbench 2 for bearing a honeycomb carrier 1, a weighing component 3 for weighing the carrier 1 before and after coating is arranged in the center of the workbench 2, a coating supply mechanism 4 is arranged right below the workbench 2, a fixing mechanism 5 for fixing the carrier 1 and a vacuum pumping mechanism 6 for pumping coating are arranged above the workbench 2, and the coating is pumped from the coating supply mechanism 4 to the carrier 1 fixed by the fixing mechanism 5 by the vacuum pumping mechanism 6 under negative pressure to complete coating; the weighing component 3 adjusts the negative pressure of the vacuum material pumping mechanism 6 during pumping according to the weight difference of the carrier 1 before and after coating;
the vacuum pumping mechanism 6 comprises a vacuum cover 61 arranged right above the fixing mechanism 5, the vacuum cover 61 is connected with a driving cylinder 53 fixed on the rack, and the driving cylinder 53 drives the vacuum cover to vertically move; a negative pressure plate 62 is vertically and slidably mounted on the inner wall of the vacuum cover 61, the lower part of the vacuum cover 61 is a sealing section, and the negative pressure plate 62 vertically slides in the sealing section; the negative pressure plate 62 is fixedly provided with a fixing rod 63, the fixing rod 63 is provided with a driving unit, and the driving unit drives the negative pressure plate 62 to vertically move through the fixing rod 63 to form negative pressure absorbing paint.
The motor vehicle with the tail gas reaching the standard needs an exhaust system with excellent performance indexes to support, namely needs an excellent three-way catalyst to treat the waste gas discharged by the automobile, wherein the honeycomb coating is a core component in the automobile tail gas catalyst, and whether the honeycomb coating is uniformly and completely coated or not finally influences the performance and the service life of the catalyst, so whether the honeycomb coating is uniformly and completely coated or not needs to be detected when the honeycomb carrier 1 is coated and produced at present. As shown in figure 1, the invention provides an automatic on-line weighing system of a honeycomb coating applied to an automobile exhaust system, which can automatically weigh a honeycomb carrier 1 before and after coating the carrier 1 respectively, and judge whether the coating is uniformly and completely coated according to the weight of the carrier 1 before and after coating.
As shown in figure 1, in the invention, in operation, an uncoated carrier 1 is firstly moved to a weighing component at the center of a workbench 2, and the weighing component is used for weighing for the first time and recording data; then the fixing mechanism 5 clamps and fixes the carrier 1 on the workbench 2, thereby avoiding the influence on coating caused by the displacement of the carrier 1 in the subsequent coating process. Then the vacuum material pumping mechanism 6 starts to work, and as shown in fig. 1 and fig. 2, the driving cylinder 53 drives the vacuum cover 61 to move down to completely cover the upper end of the carrier 1, at this time, the negative pressure plate 62 is located at the lower position of the vacuum cover 61, and the connection between the vacuum cover 61 and the carrier 1 is sealed, so as to avoid air leakage in the vacuum cover 61 when the subsequent negative pressure sucks the coating material, so that negative pressure cannot be formed, and the coating material of the carrier 1 by the vacuum material pumping mechanism 6 is influenced. Then the negative pressure plate 62 moves upwards under the driving of the driving unit, because the negative pressure plate 62 slides on the sealing section at the lower part of the vacuum cover 61, and the joint of the vacuum cover 61 and the carrier 1 is sealed, the negative pressure is generated at the part of the negative pressure plate 62 and the upper end of the carrier 1 along with the upward movement of the negative pressure plate 62, the external air pressure can press the paint in the paint supply mechanism 4 at the bottom of the carrier 1 due to the pressure difference, and the paint in the paint supply mechanism 4 is pressed upwards into the carrier 1 for coating, so as to form a coating. After the coating is completed, the driving unit returns to the low position of the negative pressure plate 62, the negative pressure disappears, and the liquid pressed by the air pressure difference falls into the coating material supply mechanism 4 again due to the self gravity. Finally, the driving air cylinder 53 drives the vacuum ring to be separated from the carrier 1, and meanwhile, the fixing mechanism 5 is unlocked, so that the vacuum cover 61 and the fixing mechanism 5 are prevented from acting on the carrier 1 to influence the second weighing of the carrier 1. At the moment, the weighing component 3 carries out second weighing on the coated carrier 1, records data and compares the data with the data during first weighing, and the negative pressure of the vacuum material pumping mechanism 6 during pumping is adjusted according to the weight difference of the coated carrier 1 before and after coating. The invention can respectively and automatically weigh the carrier 1 before and after coating the honeycomb carrier 1, judge whether the coating is uniformly and completely coated according to the weight of the carrier 1 before and after coating, and adjust the coating amount of the coating according to the weight difference of the carrier 1 before and after coating, thereby avoiding the influence of the undersize coating amount on the tail gas treatment efficiency of the catalyst; and avoids the waste of the coating caused by the overlarge coating amount of the coating, increases the cost, and even blocks the honeycomb-shaped channel on the carrier 1 to influence the tail gas treatment efficiency of the catalyst.
As a further aspect of the present invention, the fixing mechanism 5 includes a fixing ring 51 vertically slidably mounted on the worktable 2, and an inflatable assembly for clamping the carrier 1 is disposed in the fixing ring 51, and is used for inflating and clamping the carrier 1 during the coating process; the upper end of the fixing ring 51 is fixedly connected with the lower end of the vacuum cover 61 in a sealing way; after the driving cylinder 53 drives the fixing ring 51 to move to the periphery of the carrier 1, the expansion assembly 52 inflates to clamp the carrier 1, and after the expansion assembly 52 inflates, the expansion assembly expands between the inner side of the fixing ring 51 and the periphery of the carrier 1 to form a seal.
As shown in fig. 3 and 4, the fixing mechanism 5 is provided as a fixing ring 51, the fixing ring 51 moves to the outer side of the carrier 1 and covers the carrier 1 during operation, and then the expansion assembly 52 on the inner wall of the fixing ring 51 starts to inflate for fixing. In the actual material pumping process, the lower end of the vacuum cover 61 of the invention needs to be sealed and separated from the upper end of the carrier 1, and the common connection mode is difficult to ensure the sealing property, so the invention fixedly connects the upper end of the fixing ring 51 and the lower end of the vacuum cover 61 in a sealing way, then the carrier 1 is sleeved in the fixing ring 51, after the expansion component 52 is inflated and expands between the inner side of the fixing ring 51 and the periphery of the carrier 1 to form a seal, the lower end of the vacuum cover 61 and the upper end of the carrier 1 can also be sealed, thus the air leakage can not occur when the vacuum material pumping mechanism 6 pumps materials, and the stability of the negative pressure can be ensured. The expansion assembly 52 is adopted for clamping in the invention because the mode is simple to clamp and is convenient for sealing the space between the inner side of the fixing ring 51 and the periphery of the carrier 1, and the mode can be suitable for carriers 1 with different sizes and has wide applicability. In addition, the fixing ring 51 is fixedly and hermetically connected with the vacuum cover 61, so that the fixing ring 51 can be simultaneously driven to be separated from the carrier 1 when the vacuum cover 61 is reset, and the phenomenon that the fixing ring 51 and the vacuum cover 61 act on the carrier 1 to influence the secondary weighing of the carrier 1 is avoided.

The present invention provides an embodiment of a driving unit, as shown in fig. 3, when the present invention works, an external power source drives a driving gear 64 to rotate, the driving gear 64 drives a threaded sleeve 66 to rotate, the threaded sleeve 66 is in threaded connection with a threaded section 65 on a fixing rod 63, so that the threaded sleeve 66 drives the fixing rod 63 to move upwards, and a negative pressure plate 62 fixedly connected with the fixing rod 63 also slides vertically upwards in a vacuum housing 61. This driving method can apply a large force to the negative pressure plate 62, and it is ensured that the negative pressure plate 62 is not reset by a pressure difference.
As a further scheme of the invention, the driving unit comprises an external driving source and a driving gear 64 which is rotatably arranged on the inner top surface of the vacuum cover 61, a supporting rod 67 is further arranged between the driving gear 64 and the negative pressure plate 62, and one end of the supporting rod 67 is in ball joint with the lower tooth surface of the driving gear 64, and the other end of the supporting rod 67 is in ball joint with the upper end surface of the negative pressure plate 62.

The driving mode enables the stress of the negative pressure plate 62 to be uniform, and the supporting rods 67 are arranged on the negative pressure plate 62 at intervals around the circumference of the fixing rod 63, so that the negative pressure plate 62 can move upwards smoothly.
As a further aspect of the present invention, there is further included an agitation mechanism 7 for agitating the coating material in the coating material supply mechanism 4 before coating; the stirring mechanism 7 comprises an inner gear ring 71, a planetary gear 73 and a driving gear 72 externally connected with a power supply; the inner gear ring 71 is fixedly connected with the driving cylinder 53, the vacuum cover 61 is fixedly arranged on the inner gear ring 71, and the fixing ring 51 is connected with the driving cylinder 53 through the vacuum cover 61 and the inner gear ring 71; a driving gear 72 is coaxially and rotatably mounted in the middle of the inner gear ring 71, planetary gears 73 are arranged on the periphery of the driving gear 72 at intervals, the planetary gears 73 are meshed with the driving gear 72 and the inner gear ring 71, a stirring rod 74 is coaxially arranged on the planetary gears 73, one end of the stirring rod 74 is connected with the planetary gears 73 in a key mode, and the other end of the stirring rod 74 is inserted into the paint supply mechanism 4 to stir paint; the fixed ring 51 is vertically slidably mounted on the stirring rod 74.
In order to ensure that the coating material in the coating material supply mechanism 4 does not deteriorate in fluidity due to standing for a long time, the present invention is provided with an agitation mechanism 7. As shown in fig. 4, before the driving cylinder 53 drives the vacuum hood 61 and the fixed ring 51 to move down, the driving gear 72 starts to rotate under the driving of the external power source, at this time, because the ring gear 71 is fixed to the driving cylinder 53, the ring gear 71 does not rotate, the planetary gear 73 revolves while rotating, the planetary gear 73 drives the stirring rod 74 to rotate while revolving around the carrier 1, and the paint in the paint supplying mechanism 4 is stirred to avoid the reduction of fluidity. After the stirring is finished, the driving gear 72 stops moving, the driving cylinder 53 drives the vacuum cover 61 and the fixing ring 51 to move downwards, and the stirring rod 74 is limited by the vacuum cover 61 to move, so that the influence on the material pumping of the subsequent vacuum material pumping mechanism 6 due to the fluctuation of the coating in the coating supply mechanism 4 caused by the stirring is avoided.
As a further proposal of the invention, the device also comprises a control mechanism 8 for adjusting the negative pressure during the coating of the vacuum material pumping mechanism 6 by changing the movement amount of the negative pressure plate 62; the drive gear 64 passes through control mechanism 8 and is connected with external drive source, control mechanism 8 includes the metering gear 81 with drive gear 64 meshing, metering gear 81 is incomplete gear, control mechanism 8 accepts the signal that the subassembly 3 transmitted of weighing, and the deviation degree drive metering gear 81 of the weight difference of carrier 1 and the predetermined standard value is just, the counter rotation around according to weighing twice.
The invention drives the metering gear 81 to rotate forwards and backwards according to the deviation degree of the weight difference value of the carrier 1 before and after weighing twice and the preset standard value, so as to adjust the initial position of the negative pressure plate 62 and further control the negative pressure of the vacuum material pumping mechanism 6 during paint pumping. The metering gear 81 is provided as an incomplete gear in the present invention in order to avoid accidental errors, and the position of the suction plate 62 is adjusted only when the same type of coating is incomplete several times. Under the condition that the moving distance of the negative pressure plate 62 is fixed, when the weight difference value is smaller than a preset standard value, which indicates that the coating is incomplete, the initial position of the negative pressure plate 62 needs to be adjusted downwards, and the negative pressure of the vacuum material pumping mechanism 6 during the paint pumping is increased; when the weight difference value is larger than the preset standard value, which indicates that the coating is excessive, the initial position of the negative pressure plate 62 needs to be adjusted upwards, and the negative pressure of the vacuum material pumping mechanism 6 during paint pumping is reduced. Compared with the method of controlling the negative pressure of the vacuum material pumping mechanism 6 during paint pumping by adjusting the moving distance of the negative pressure plate 62, the moving distance of the negative pressure plate 62 is constant, so that error superposition caused by repeated adjustment and displacement of the negative pressure plate 62 is avoided.
