Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning tables and their accessories, and in particular relates to a device for measuring the height of sandpaper surface on a cleaning table using a force meter. Background Technology

[0002] A probe cleaning station is a device used to clean and maintain probes. Probes are one of the most important inspection components in the production of circuit board chips. To ensure the integrity and accuracy of the inspection results, a probe cleaning station is needed to clean the probes and ensure their cleanliness. The probe cleaning station mainly consists of a table, sandpaper, clamping parts, and a power unit. The clamping parts and the power unit are installed on the table. The sandpaper is placed on the upper surface of the table. The probe is clamped by the clamping parts, and then the power unit drives the clamping parts to move so that they are in contact with the sandpaper on the table to achieve the effect of friction cleaning.

[0003] Chinese patent application CN216066845U discloses a large-table cleaning table, including a cleaning table base. The base has first connecting grooves at both ends, and a connecting groove is installed on the base between these grooves. A cleaning table surface is snapped onto the base, and cleaning sandpaper is applied to the surface of the cleaning table surface. A slot is provided at the bottom of the cleaning table surface, and a second connecting groove is provided inside the slot. The second connecting groove and the first connecting groove are connected by a locking block. Strong magnets are provided at both ends of the second connecting groove corresponding to the connecting groove. This invention effectively facilitates the connection and disassembly of the cleaning table surface and the cleaning table base, making it easier to replace the cleaning table surface and improve the usability of the cleaning device.

[0004] The aforementioned large-table cleaning station has a cleaning table surface attached to its base. The surface of the cleaning table is covered with cleaning sandpaper, which is laid flat on the cleaning table. However, the sandpaper is a consumable part; its surface wears down with increasing contact time and pressure with the probes. There is no structure on the table to detect the wear, forcing manual judgment of its usability, which introduces significant errors and creates major cleaning drawbacks for subsequent probe cleaning. Furthermore, the sandpaper is glued to the cleaning table surface, requiring peeling and re-attaching for replacement. The adhesive backing increases the gap between the sandpaper and the cleaning table surface, and decreases the gap between the sandpaper and the probe, easily leading to over-cleaning. The excessive adhesion also makes it extremely difficult to remove when replacement is needed. To address these problems, we provide a force gauge-based device for measuring the height of the sandpaper surface on the cleaning table, thus solving the aforementioned issues. Utility Model Content

[0005] The purpose of this invention is to provide a device for measuring the height of sandpaper on a cleaning table using a force meter. The device uses a lifting component to push the sandpaper body to be flush with the upper surface of the cleaning table, and then uses a detection component to detect the thickness of the sandpaper body. With the cooperation of the unloading component and the heating plate, the sandpaper body can be easily peeled off from the cleaning table and replaced, thus solving the problems of the aforementioned large-table cleaning table.

The lifting components include fixing sleeves fixed to the bottom side wall of the table panel and electric push rods installed on the cleaning table surface. The table panel is connected to the fixed sleeve. Detection components are installed on the bottom sidewalls of the left and right ends of the table panel. Each detection component includes a hanging ring fixed to the bottom sidewall of the left end of the table panel, and a hook is attached to the hanging ring. The hook is fixedly installed on the detection end of the tension gauge, and the other end of the tension gauge is connected to the needle cleaning table. A material ejection component is also provided on the right end of the needle cleaning table. The material ejection component includes a material ejection plate embedded in the needle cleaning table, and a pneumatic push rod is fixedly installed on the bottom sidewall of the material ejection plate.

[0007] The present invention is further configured such that side grooves are provided at the left and right ends of the countertop groove, and bottom grooves are provided on the bottom sidewalls of the side grooves; side blocks are installed at the left and right ends of the countertop panel, and the side blocks slide in cooperation with the side grooves.

[0008] The present invention is further configured such that the detection component includes a second fixing frame fixed in the bottom groove, and the second fixing frame is also fixedly installed on the bottom side wall of the tension gauge. A bottom hole is also provided on the bottom side wall of the side block, and the lifting ring is fixedly installed in the bottom hole.

[0009] The present invention is further configured such that mounting holes are provided at the four corners of the bottom sidewall of the tabletop groove, and a total of four lifting components are provided, each of which is correspondingly installed in the mounting holes.

[0010] The present invention is further configured such that the lifting assembly includes a fixing bracket fixedly installed in the mounting hole, and the fixing bracket is fixedly installed on the bottom side wall of the electric push rod. The telescopic end of the electric push rod is fixedly installed with a connecting column, and the electric push rod is connected to the fixing sleeve through the connecting column.

[0011] The present invention is further configured such that an installation groove is provided at the edge of the upper side wall of the table panel, and the heating plate is embedded in the installation groove; a plate groove is provided on the inner side of the installation groove and at the right end of the table panel.

[0012] The present invention is further configured such that the ejector plate is embedded in the plate groove, and the upper surface of the ejector plate is flush with the upper surface of the table panel, and a connecting groove is also provided on the bottom side wall of the ejector plate.

[0013] The present invention is further configured such that the ejector plate is connected to the telescopic end of the pneumatic push rod through a connecting groove, and a fixing frame three is also installed on the bottom side wall of the pneumatic push rod, and the pneumatic push rod is connected to the bottom inner wall of the table groove through the fixing frame three.

[0014] This utility model has the following beneficial effects: 1. This utility model includes a table panel, a lifting assembly, and a detection assembly. The table panel has lifting assemblies at each of its four corners on the bottom sidewall. Each lifting assembly includes a fixing sleeve fixed to the bottom sidewall of the table panel and a fixing frame one set within the table surface groove of the cleaning table. An electric push rod is fixedly mounted on the fixing frame one, and the end of the electric push rod has a connecting post connected to the fixing sleeve. Side blocks that slidably connect to the table surface groove are also provided on the left and right sides of the table panel. The detection assembly includes a lifting ring fixed to the bottom sidewall of the side block and a fixing frame two fixed to the cleaning table. A tension gauge is fixedly mounted on the fixing frame two, and the end of the tension gauge has a hook for connecting to the lifting ring. In use, the electric push rod operates, causing the table panel to move up and down, making the upper sidewall of the sandpaper body adhered to its upper end flush with the upper surface of the cleaning table. Meanwhile, since the table panel is connected to the tension gauge via hooks and rings, when the upper sidewall of the sandpaper body is flush with the upper surface of the cleaning table, this operation can be calibrated using, for example, an infrared rangefinder built into the cleaning table. The tension gauge count is then zeroed. At this point, the upper surface of the sandpaper body is flush with the upper surface of the cleaning table, meaning the height of the sandpaper body is fixed. The tension value measured by the tension gauge reflects the total weight of the table panel and the sandpaper body at this time. As the sandpaper body is continuously worn by the probe, its mass and thickness decrease simultaneously. Therefore, in each test, to achieve the same reference height, the reading of the tension gauge will also decrease accordingly due to the reduction in the mass of the sandpaper body. By monitoring the change in the tension gauge reading, the thickness loss of the sandpaper body can be indirectly and quantitatively assessed.

[0015] 2. This utility model, by setting up a heating plate and a material ejection assembly, has a heating plate embedded around the upper surface of the table panel, and a groove on the right end of the table panel. The material ejection assembly includes a material ejection plate embedded in the groove, and a pneumatic push rod installed on the bottom side wall of the material ejection plate. A fixing frame three is fixedly installed on the bottom side wall of the pneumatic push rod, and the fixing frame three is fixedly installed on the cleaning table. When in use, the heating plate works and generates heat, which in turn heats the table panel. The sandpaper body is adhered to the table panel. After the table panel is heated, the adhesion between the sandpaper body and the table panel will decrease. Then, the pneumatic push rod in the material ejection assembly will work, extend, and drive the material ejection plate on the shaft end to move upward and pass through the groove of the table panel. At this time, one end of the sandpaper body with extremely low adhesion is pushed out of the table panel, thereby easily peeling off the sandpaper body that is stuck to the table panel.

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1 Please see Figure 1-3 This utility model is a measuring device for measuring the height of sandpaper on a cleaning table using a force meter. It includes a cleaning table 1, a table panel 2, a lifting component 4, and a detection component 5. The lifting component 4 can lift the table panel 2 and the sandpaper body 3 on it, and then the detection component 5 can pull it down and detect the traction force in real time.

[0024] Specifically, the upper surface of the cleaning table 1 is provided with a table groove 101, and the two sides of the table groove 101 are provided with side grooves 102, and the bottom side wall of the side groove 102 is provided with a bottom groove 102a. The bottom side wall of the four corners of the table groove 101 is provided with mounting holes 103. The cleaning table 1 is slidably engaged with the table panel 2 through the table groove 101. The left and right ends of the table panel 2 are integrally provided with side blocks 201, which are slidably engaged with the side grooves 102. The upper surface of the table panel 2 is also bonded with a sandpaper body 3.

[0025] Furthermore, the lifting assembly 4 includes a first fixing bracket 402 fixed in the mounting hole 103, and an electric push rod 401 is also installed in the first fixing bracket 402. A connecting column 403 is fixedly installed on the upper end face of the electric push rod 401, and the connecting column 403 is connected to the bottom side wall of the platform 2 through a fixing sleeve 404. The detection assembly 5 includes a second fixing bracket 502 fixed in the bottom groove 102a, and a tension gauge 501 is installed in the second fixing bracket 502. A hook 503 is fixedly installed on the detection end of the tension gauge 501, and a bottom hole 203 is opened on the bottom side wall of the side block 201 corresponding to the hook 503. A lifting ring 504 is installed in the bottom hole 203, and the lifting ring 504 is hooked to the hook 503.

[0026] The operation process of this embodiment is as follows: During use, the electric push rod 401 operates, driving the table panel 2 to move up and down, so that the upper side wall of the sandpaper body 3 bonded to its upper end is flush with the upper surface of the cleaning table 1. At the same time, since the table panel 2 is connected to the tension gauge 501 through the hook 503 and the lifting ring 504, when the upper side wall of the sandpaper body 3 is flush with the upper surface of the cleaning table 1, this operation can be calibrated by, for example, an infrared rangefinder built into the cleaning table. This infrared rangefinder is a standard configuration on the cleaning table. When the pressure gauge 501 counts to zero, the upper surface of the sandpaper body 3 is flush with the upper surface of the cleaning table 1, meaning the height of the sandpaper body 3 is fixed. The tensile force measured by the pressure gauge 501 reflects the total weight of the table 2 and the sandpaper body 3 at this time. As the sandpaper body 3 is continuously worn by the probe, its mass and thickness decrease synchronously. Therefore, in each test, in order to achieve the same reference height, the reading of the pressure gauge 501 will also decrease accordingly due to the reduction in the mass of the sandpaper body 3. By monitoring the change in the reading of the pressure gauge 501, the thickness loss of the sandpaper body 3 can be indirectly and quantitatively assessed.

[0027] Example 2 Please see Figure 3-4 Based on embodiment 1, an electric heating plate 202 and a material ejection component 6 are also provided. The electric heating plate 202 can heat the adhesive surface at the bottom of the sandpaper body 3. After being heated, the adhesive surface and the table panel 2 become less sticky. Then, the material ejection component 6 can easily push the sandpaper body 3 off the table panel 2.

[0028] Specifically, an installation groove 205 is provided at the edge of the upper side wall of the tabletop 2, and an electric heating plate 202 is embedded in the installation groove 205, and a plate groove 204 is provided at the right end of the tabletop 2.

[0029] Furthermore, the ejector assembly 6 includes an ejector plate 603 embedded in the plate groove 204, and the upper end face of the ejector plate 603 is flush with the upper end face of the table panel 2. A connecting groove 603a is provided on the bottom side wall of the ejector plate 603, and the ejector plate 603 is fixedly connected to the upper end of the pneumatic push rod 601 through the connecting groove 603a. A fixing bracket 602 is also fixedly installed on the bottom side wall of the pneumatic push rod 601, and the fixing bracket 602 is connected to the inner wall of the table groove 101 on the needle cleaning table 1.

[0030] The operation process of this embodiment is as follows: When in use, the heating plate 202 works and generates heat, which in turn heats the table panel 2. The sandpaper body 3 is adhered to the table panel 2. After the table panel 2 is heated, the adhesion between the sandpaper body 3 and the table panel 2 will decrease. Then, the pneumatic push rod 601 in the ejector assembly 6 works and extends, driving the ejector plate 603 on the shaft end to move upward and pass through the plate groove 204 of the table panel 2. At this time, one end of the sandpaper body 3 with extremely low adhesion is pushed out of the table panel 2, thereby easily peeling off the sandpaper body 3 that is stuck to the table panel 2.
