Description

Technical Field

[0001] This utility model relates to a wire mesh cleaning device. Background Technology

[0002] The components of the vacuum membrane self-adsorption box include a base plate, a mesh plate stacked on the base plate, and a thin film covering the mesh plate. The vacuum membrane self-adsorption box can be used to place small wafers and filters to avoid mutual friction damage during transportation, thereby preventing losses.

[0003] However, in the production process of vacuum membrane self-adsorption boxes, the raw material for the mesh plate is wire mesh. Before use, the wire mesh needs to be cleaned to prevent stains on the wire mesh from affecting the performance of the vacuum membrane self-adsorption box. The existing cleaning method is as follows: place the wire mesh on a relevant fixture, then place the fixture containing the wire mesh into a frame with perforations, and then place the frame with perforations into an ultrasonic cleaning tank for ultrasonic cleaning. During ultrasonic cleaning, it is necessary to pause the ultrasonic cleaning multiple times so that the frame can be manually shaken up and down to further remove the stains from the wire mesh. However, interrupting the ultrasonic cleaning multiple times for manual shaking is not only cumbersome and time-consuming, but also leads to a decrease in overall production efficiency.

After washing, the wire mesh rack containing the wire mesh is placed on the slow pulling support. The slow pulling mechanism drives the slow pulling support to rise at a certain speed until the wire mesh rack containing the wire mesh is removed from the clean water in the slow pulling tank. Finally, the wire mesh rack containing the wire mesh is placed on the fixed support in the drying tank for drying.

[0021] In this embodiment, to achieve washing, the washing tank includes at least two cleaning tanks 14. The first cleaning tank from left to right contains washing water 15 with washing liquid, while the other cleaning tanks contain clean water 16. That is, the first washing water is used to clean stains, and the subsequent clean water is used for further cleaning or to remove the washing water from the surface of the wire mesh after the first cleaning. An existing ultrasonic generator 17 is installed on the bottom of the outer side of the washing tank. The ultrasonic generator inputs ultrasonic waves into the cleaning tank through a transducer, and the wire mesh rack containing the wire mesh is cleaned by ultrasonic waves. The washing support includes washing support plates corresponding to the cleaning tanks, that is, each... Each washing tank is equipped with a corresponding washing support plate 18. The washing support plate has a frame structure, and several crossbars 19 for supporting the wire mesh placement rack are arranged at intervals within the frame structure. Washing limit baffles 20 are provided around the washing support plate. The washing limit baffles can also be frame structures to facilitate the flow of clean water or cleaning solution during washing. Washing support rods 21 are symmetrically arranged on the left and right sides of the rear side of the washing support plate. A washing fixing rod 22 is horizontally placed between the upper ends of the washing support rods. In use, the washing driving mechanism drives the washing fixing rod to move up and down, thereby driving the entire washing support to move up and down, making the washing more thorough.

[0022] In this embodiment, to enable the washing drive mechanism to drive the washing fixed rod to move up and down, the specific structure of the washing drive mechanism is as follows: The washing drive mechanism includes a horizontal lifting plate 23 that is slidably connected to the rear side of the washing workbench. The horizontal lifting plate has several guide holes, and the washing workbench is provided with guide posts 24 corresponding to the guide holes. The guide posts and guide holes cooperate to provide the lifting foundation for the horizontal lifting plate. A connecting rod 25 that moves synchronously with the horizontal lifting plate is connected to the front side of the horizontal lifting plate. The connecting rod and the horizontal lifting plate are connected by several horizontal connecting posts 26. The washing fixed rod is screwed onto the connecting rod. That is, the washing fixed rods on the washing support plates in each washing tank are all fixed to the connecting rods to realize the synchronous movement of the washing tanks. At the same time, a cover plate 27 can be provided on the washing tank. The cover plate is provided with a clearance opening corresponding to the washing support rod.

The lower end of the electric push rod is fixed to the cleaning worktable, and the telescopic end of the electric push rod is fixed to the bottom of the horizontal lifting plate. The horizontal lifting plate is raised and lowered by extending and retracting the telescopic end of the electric push rod. A washing roller 31 is rotatably connected to the washing support rod. The washing roller is rolled and connected to the wall of the cleaning tank to facilitate the smooth movement of the washing support rod during raising and lowering.

[0024] In this embodiment, the handle has the following structure: the handle includes a horizontally arranged lifting rod 32, with both ends of the lifting rod bent downwards to form a bent rod 33. The ends of the two bent rods are respectively fixed to the front and rear ends of the side of the cube frame. In order to fix the wire mesh placement rack on the washing bracket and prevent the wire mesh placement rack from detaching due to the up and down movement of the washing bracket, a handle locking mechanism 34 is provided on the washing support rod. The handle locking mechanism includes a cantilever rod 35. The rear end of the cantilever rod is fixed to the washing support rod, and a locking block 36 is installed on the front end of the cantilever rod. A locking groove is provided on the upper surface of the locking block corresponding to the handle. A spring pin 37 is provided in the locking groove to lock the handle in the locking groove. In use, the wire mesh placement rack is placed on the washing bracket, and the lifting rod of the handle is locked into the locking groove. The spring pin prevents the lifting rod from detaching. At this time, due to the presence of the washing support plate, the washing limit baffle, and the spring pin of the locking groove, the wire mesh placement rack is fixed.

[0025] In this embodiment, to achieve slow-pull dehydration of the wire mesh after washing, the slow-pull support includes a slow-pull support plate 38, the structure of which is similar to that of the washing support plate. Slow-pull limiting baffles 39 are provided around the slow-pull support plate, the structure of which is similar to that of the washing limiting baffle. Slow-pull support rods 40 are symmetrically arranged on the left and right sides of the rear side of the slow-pull support plate. A slow-pull fixing rod 41 is horizontally placed between the upper ends of the washing support rods. During slow-pull dehydration, the slow-pull mechanism slowly and uniformly lifts the wire mesh placement rack containing the wire mesh after washing by slowly and uniformly lifting the slow-pull fixing rod. This effectively removes large water droplets or bubbles from the surface of the workpiece, preventing residual water spots or bubbles during subsequent drying and packaging, and improving the cleaning effect. Since the slow-pull dehydration is performed slowly and uniformly, there is no need to set up an additional handle locking mechanism. Of course, it is also possible to set up a handle locking mechanism.

[0026] In this embodiment, to achieve the slow-pull mechanism lifting the slow-pull fixing rod, the slow-pull mechanism includes a vertically arranged lifting screw 42 driven to rotate by a motor. The lifting screw is rotatably connected to the rear side of the cleaning workbench. A lifting frame 43 is mounted on the lifting screw and rises and falls with the rotation of the lifting screw. Specifically, a screw nut is provided on the lifting screw and rises and falls with the rotation of the lifting screw. The screw nut is fixed to the lifting frame. Guide rails 44 are installed on the left and right sides of the lifting frame on the rear side of the cleaning workbench, slidingly engaging with the sides of the lifting frame. The slow-pull fixing rod is fixed to the front side of the lifting frame. A slow-pull roller 45 is rotatably connected to the slow-pull support rod. The rollers abut against the wall of the slow-pull trough. A cover 46 is provided on the rear side of the cleaning workbench corresponding to the slow-pull mechanism. The guide rails are vertically arranged on the left and right sides inside the cover. The lifting frame is provided with guide grooves that cooperate with the guide rails. Through the cooperation of the guide grooves and the guide rails, the lifting frame can achieve a smooth movement. At the same time, the front side of the lifting frame is connected to a slow-pull lifting drive rod 48 via at least two horizontal rods 47. The slow-pull lifting drive rod is located outside the cover. The cover is provided with a clearance 49 corresponding to the horizontal rods. The slow-pull fixing rod is fixed to the slow-pull lifting drive rod. The lifting screw is driven by a motor to rotate, which drives the lifting frame to rise and fall, and then drives the slow-pull fixing rod to rise and fall, so as to realize the slow-pull mechanism lifting the slow-pull fixing rod.
