[0002] Workpieces need to be transferred back and forth among various stations in surface treatment processes such as electroplating and oxidation, and the workpieces are cleaned during the transfer process, which can also achieve a moisturizing effect on the surface of the workpieces.
[0003] In the prior art, a water washing transfer vehicle is usually used to transfer workpieces. The water washing transfer vehicle is usually located at the end of a U-shaped electroplating line or an anode oxidation line and is used to transfer workpieces between different process lines while cleaning the workpieces and achieving a moisturizing effect on the surface of the workpieces. The water washing transfer vehicle is mainly composed of a complete water washing tank and a transmission mechanism at the bottom. In some cases where the distance is relatively long (> 20 m), the mass of the water washing tank itself plus the mass of the water solution in the tank is large. If the water washing transfer vehicle moves too fast within a limited cycle time, the buffer time for starting and stopping the water washing transfer vehicle will be greatly increased to offset the influence of the large mass inertia, which will inevitably reduce the work efficiency, prolong the cycle time, and increase the manufacturing cost.

[0023] This utility model provides a long-distance moisturizing rapid transfer device for transferring workpieces. It includes an empty trough, a trough surface transfer vehicle set on the top of the empty trough, and a spray assembly. The empty trough connects the starting point and the ending point of the workpiece transfer. The workpiece is hoisted on the trough surface transfer vehicle and located inside the empty trough. The spray assembly is set inside the empty trough and arranged along the length of the empty trough for spraying and moisturizing the workpiece during the transfer process.
[0024] Example 1
[0025] like Figures 1-3 As shown, this embodiment discloses a long-distance moisturizing rapid transfer device for transferring workpiece 410, including an empty trough 100, a trough surface transfer cart 400 disposed on top of the empty trough 100, and a spray assembly. The empty trough 100 is a trough structure with an open top, and its two ends are respectively connected to the starting point and the ending point of the transfer of workpiece 410 (i.e., Figure 1 (Lines A and B in the diagram), the trough surface transfer vehicle 400 is equipped with a fly bar, and the workpiece 410 is hoisted onto the trough surface transfer vehicle 400 by the fly bar, and the entire workpiece 410 is located inside the empty trough 100. The spray assembly is set inside the empty trough 100 and arranged along the length of the empty trough 100, and is used to spray and moisturize the workpiece 410 and clean the surface of the workpiece 410 during the transfer process.
[0026] In this embodiment, the spray assembly includes a main water supply pipe 200 and multiple spray branch pipe units. The main water supply pipe 200 is located below the empty tank 100 and is used to provide spray water. The multiple spray branch pipe units are independently arranged and are connected to the main water supply pipe 200. The multiple spray branch pipe units are arranged along the length of the empty tank 100, thereby covering various areas along the length of the empty tank 100, thus ensuring that the workpiece 410 is always sprayed with spray water during operation.
[0027] like Figure 1 As shown, the spray branch pipe unit includes a first branch pipe 210 arranged along the height direction of the empty trough 100 and multiple spray pipes 220 arranged along the length direction of the empty trough 100. The bottom end of the first branch pipe 210 is connected to the water supply main pipe 200. The multiple spray pipes 220 are arranged sequentially on the first branch pipe 210 along the height direction of the empty trough 100, and each spray pipe 220 has multiple nozzles 230.
[0028] Furthermore, each spray branch pipe unit includes two first branch pipes 210, which are respectively attached to the side walls on both sides of the empty trough 100. Multiple spray pipes 220 are attached to the side walls on both sides of the empty trough 100, and the opening direction of the nozzles 230 is facing the center of the empty trough 100, so as to ensure that the spray water sprayed by the nozzles 230 can be sprayed onto the workpiece 410.
[0029] In the embodiment, the plurality of spray branch pipe units are sequentially attached along the length direction of the air slot 100, and each spray branch pipe unit is responsible for the spraying of the area where it is located. Each group of spray branch pipe units includes two first branch pipes 210, and each first branch pipe 210 is provided with five parallel spray pipes 220.
[0030] Specifically, the spray branch pipe units are provided with six groups, two of which are located at the start and end points of the workpiece 410 transfer, and the other four are located in the process of workpiece 410 transfer. The difference is that the nozzles 230 on the spray pipes 220 of the spray branch pipe units located at the start and end points of the workpiece 410 transfer are more dense than the nozzles 230 on the spray pipes 220 of the spray branch pipe units located in the process of workpiece 410 transfer. This is because the workpiece 410 is in a stationary state when it is at the start or end point of the transfer, and in order to ensure that the surface of the workpiece 410 can be covered by the sprayed water, more dense nozzles 230, that is, more nozzles 230, are needed. The coverage range of these nozzles 230 can effectively cover all areas of the surface of the workpiece 410 (each circle in the figure represents the coverage range of a nozzle 230).
[0031] Since the workpiece 410 is in a state of motion when it passes through the middle four groups of spray group branch pipe units, the number and coverage range of the nozzles 230 only need to ensure that there is no gap between the coverage ranges of multiple nozzles 230 in the height direction, and the overall range in the height direction is greater than the height of the workpiece 410. The nozzles 230 along the length direction of the air slot 100 can be set a little sparsely.
[0032] As shown in Figure 1 In the embodiment, the long-distance moisturizing and rapid transfer device further includes a control assembly, which includes a controller and a relay. The first branch pipe 210 of each spray branch pipe unit is provided with an electromagnetic valve 211, and the controller is electrically connected with the electromagnetic valve 211 of the first branch pipe 210 of each spray branch pipe unit (the electromagnetic valves 211 of the two first branch pipes 210 on the same spray branch pipe unit are controlled at the same time). The workpiece 410 is moved from the transfer start point to the transfer end point by the slot surface transfer car 400 at a uniform speed. The controller is used to calculate the position of the workpiece according to the time and the movement speed of the slot surface transfer car, so as to control the electromagnetic valve of the first branch pipe of the spray branch pipe unit at the corresponding position to be opened, and the electromagnetic valves 211 on the other first branch pipes 210 are in a closed state. Wherein, the length covered by each spray branch pipe unit along the length direction of the air slot 100 is the same.
[0033] In the embodiment, the controller adopts a PLC controller, and the corresponding electromagnetic valve can be opened at the corresponding time point by setting the movement speed of the groove surface transfer trolley and the length of each spray branch pipe unit, so that when the workpiece is located in the corresponding spray branch pipe unit, the electromagnetic valve of the spray branch pipe unit is opened to spray the workpiece.
[0034] For example, when the groove surface transfer trolley 400 drives the workpiece 410 to move to the second spray branch pipe unit (counted from the right to the left, the second one), at this time, the electromagnetic valve 211 on the second branch pipe of the second spray branch pipe unit is opened to spray the workpiece 410, and the electromagnetic valves 211 of the second branch pipes of other spray branch pipe units are all closed. Figure 1
[0035] In the embodiment, the long-distance moisturizing and rapid transfer device further comprises a collecting groove 330, the collecting groove 330 is arranged directly below the empty groove 100, the bottom of the empty groove 100 is provided with a drain hole, the drain hole is communicated with the collecting groove 330 through the first pipeline 300, and the drain hole is used for draining the spray water deposited in the empty groove 100 into the collecting groove 330.
[0036] Further, the long-distance moisturizing and rapid transfer device further comprises a water treatment assembly, the water treatment assembly comprises a filter 320, the collecting groove 330 is communicated with the water supply main pipe 200 through a second pipeline 310, and the filter 320 is arranged on the second pipeline 310. The water in the collecting groove 330 is pumped into the water supply main pipe 200 after being filtered through the filter 320.
[0037] Specifically, the collecting groove 330 is further provided with a liquid level sensor, the liquid level sensor is electrically connected with the controller, when the liquid level sensor senses that the liquid surface in the collecting groove 330 reaches a set liquid surface height, the liquid level sensor sends a first signal to the controller, the controller is further electrically connected with the filter 320, and is used for controlling the filter 320 to start after receiving the first signal, so that the water in the collecting groove 330 is pumped into the water supply main pipe 200 after being extracted and filtered.
[0038] The working principle of the long-distance moisturizing and rapid transfer device in the utility model is as follows:
[0039] The flybar workpiece 410 is placed on the groove surface transfer trolley 400 at the top of the empty groove 100 by a travelling crane, an electromagnetic valve 211 on a first branch pipe 210 of a spray branch pipe unit corresponding to a workpiece 410 transfer starting point (the workpiece 410 is placed at an initial position at the end of the A line) is opened by a PLC control system to give an electric signal, and the workpiece 410 is started to be sprayed and moisturized.
[0040] When the workpiece 410 moves from the transfer starting point to the transfer ending point (from line A to line B), the PLC control system controls the electromagnetic valve 211 on the corresponding first branch pipe 210 of the spraying branch pipe unit to open according to the time and the speed of the slot surface transfer trolley,
[0041] The spraying starts, and the electromagnetic valve 211 on the first branch pipe 210 of the spraying branch pipe unit corresponding to the position where the workpiece 410 has passed is quickly closed. When long-distance multi-section spraying is needed, the same spraying action continues until the workpiece 410 moves to the transfer ending point (line B);
[0042] After the flybar workpiece 410 is delivered, the slot surface transfer trolley 400 returns from line B to line A. Since it is an empty trolley, the spraying assembly is not started.
[0043] The water accumulated at the bottom of the empty slot 100 flows into the collection tank 330 through the first pipeline 300. When the liquid level in the collection tank 330 reaches a set height, the liquid level sensor in the collection tank 330 sends an electrical signal to the control system, and the control system controls the filter 320 to start and pump the water in the collection tank 330 into the water supply main pipe 200 after filtration.
[0044] In the embodiment, the empty slot 100 of the long-distance moisturizing and quick transfer device does not need to move, and only needs to drive the workpiece 410 to move along the length direction of the empty slot 100 through the slot surface transfer trolley 400 located at the top of the empty slot 100, so that the influence of large mass inertia does not need to be considered, the start and stop of the slot surface transfer trolley 400 almost does not need to be buffered, the tact time is shortened, and the work efficiency is improved. Moreover, the spraying assembly is arranged in the length direction of the empty slot 100, the workpiece 410 in the transfer process can be sprayed and washed, and the surface humidity of the workpiece 410 can be maintained. While meeting the tact time and process requirements, the empty slot 100 does not need to bear the pressure generated by the water solution, and can be made of thinner materials, the reinforcing ribs of the empty slot 100 wall can be made of less materials or even without reinforcing ribs, which saves the manufacturing time and material cost. Reasonably arranging the spraying pipe 220 in the empty slot 100 and selecting appropriate nozzles 230 (reducing the number of nozzles 230 of the spraying branch pipe unit in the middle part), which is beneficial to saving water resources. In the occasion where long-distance transportation is needed, the spraying branch pipe unit can be arranged in sections, and each section is automatically controlled to open and close through the electromagnetic valve 211, so that the workpiece 410 in the section is automatically opened to spray and wash the workpiece 410, and the section without the workpiece 410 is automatically closed. The collection tank 330 at the bottom collects the sprayed water, filters the water through the filter 320, and flows back to the water supply main pipe 200, which achieves the effect of once injection and multiple recycling, greatly saving water resources. Since the slot surface transfer trolley 400 does not need to consider the total mass of the water washing tank and the water solution, the power consumption requirement of the motor is relatively low, and the structure can be simpler.
[0045] In conclusion, the long-distance moisturizing and quick transferring device in the embodiment is suitable for the occasion of long-distance quick transferring of the workpiece 410, has the functions of spraying and washing and moisturizing during transferring, can recycle water resources for multiple times, reduces water resource consumption, has low manufacturing cost, and has high performance-price ratio.
[0046] It can be understood that the above embodiments are only exemplary embodiments for illustrating the principles of the present application, and the present application is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present application, and these modifications and improvements are also considered as the protection scope of the present application.
